Patent Description:
With the improvement of people's living standard and the pursuit of hairdressing art, hairdressing devices are increasingly widely used. For example, for a hair straightener, in order to reduce damage to hair during hair straightening, a steam hair straightener emerges on the market which is connected with a water delivery mechanism and evaporates water into steam during hair straightening so as to moisten the hair. However, an existing water delivery mechanism needs to be additionally provided with a hose as a water delivery pipe to deliver water. As a result, there are too many components and the structure is complex. A hairdressing device with such a water delivery mechanism is known e.g. from patent application document <CIT>.

The patent <CIT> discloses a pump for conveying a liquid, having at least one pump housing comprising at least one inlet and at least one outlet, and comprising an inner circumferential surface and a geometric axis, wherein an eccentric is arranged within the pump housing and the eccentric is moveable eccentrically relative to the pump housing around the geometric axis. A deformable element is arranged in a pump gap between the inner circumferential surface of the pump housing and an outer surface of the eccentric, wherein a conveying channel from the at least one inlet to the at least one outlet is formed by the deformable element and the inner circumferential surface of the pump housing and wherein, in addition, the deformable element is pressed against the pump housing by the outer surface of the eccentric along at least one section of the conveying channel in such a way that at least one displaceable seal of the conveying channel and at least one closed pump volume are formed in the conveying channel and which are displaceable by an eccentric movement of the eccentric for conveying the fluid along the conveying channel from the inlet to the outlet, wherein the outer surface of the eccentric has a structured surface area.

In order to solve the problem that the water delivery mechanism of the existing hairdressing device has too many components and a complex structure, the present invention provides a hairdressing device.

For solving the above technical problem the present invention provides a hairdressing device as defined in the independent claim <NUM>.

Preferably, the liquid storage device comprises a tank, a water guide pipe, and a first water suction member, wherein the water guide pipe has one end passing through the water tank and to be communicated with the outside, and an opposite end connected to the first water suction member; and the first water suction member has one end disposed on the water guide pipe and an opposite end extending in the tank.

Compared with the prior art, the hairdressing device according to the present invention have the benefits as follows.

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention instead of limiting the present invention.

With reference to <FIG>, a first embodiment of the present invention provides a water pumping device <NUM> for being connected with a liquid storage device so as to deliver a liquid in the liquid storage device. The water pumping device <NUM> comprises a chamber p for containing the liquid and a squeezing device <NUM>.

Specifically, the chamber p is defined by a hard wall surface and a deformable wall surface. In some embodiments, the chamber p may be entirely defined by the deformable wall surface.

With reference to <FIG>, the water pumping device <NUM> comprises a flexible pump core <NUM>, an outer bracket <NUM> and a baffle <NUM>, the outer bracket <NUM> sleeving the flexible pump core <NUM>, and the baffle <NUM> being disposed between the flexible pump core <NUM> and the outer bracket <NUM>, extending from one of the flexible pump core <NUM> and the outer bracket <NUM> and being positioned on the other of the flexible pump core <NUM> and the outer bracket <NUM>. <FIG> shows a schematic sectional view of the chamber p. The flexible pump core <NUM> is made of the deformable material.

Specifically, with reference to <FIG>, <FIG> and <FIG>, the flexible pump core <NUM> is ring-shaped (as shown in <FIG>). The outer bracket <NUM> takes the shape of a ring with a notch <NUM> (as shown in <FIG>). The baffle <NUM> is fixed to the flexible pump core <NUM>, and the end of the baffle <NUM> away from the flexible pump core <NUM> is clamped into the notch <NUM> of the outer bracket <NUM>. In some embodiments, the baffle <NUM> may be fixed to the outer bracket <NUM>, and the end of the baffle <NUM> away from the outer bracket <NUM> is tightly attached to the flexible pump core <NUM> as long as the baffle <NUM> is disposed between the flexible pump core <NUM> and the outer bracket <NUM> and separates a first water delivery channel <NUM> and a second water delivery channel <NUM>.

Specifically, the baffle <NUM> is made of the deformable material. The thickness of the side of the baffle <NUM> close to the flexible pump core <NUM> is less than that of the side thereof away from the flexible pump core <NUM>. When the squeezing device <NUM> squeezes a position of the flexible pump core <NUM> corresponding to the baffle <NUM>, the side of the baffle <NUM> close to the flexible pump core <NUM> moves to the side away from the flexible pump core <NUM> to make way for the squeezing device <NUM> and thus the squeezing device <NUM> continues to move.

Specifically, the chamber p takes the shape of a ring with an opening. The baffle <NUM> is located at the opening of the chamber p. The squeezing device <NUM> is an eccentric wheel <NUM>. In some embodiments, the squeezing device <NUM> may be a circular roller or others. The chamber p may take other shapes, such as a fan shape, an elliptic shape with an opening, and a linear shape as long as two opposite ends of the chamber p are communicated with the first water delivery channel <NUM> and the second water delivery channel <NUM> respectively. The squeezing device <NUM> periodically squeezes the deformable material from one end of the chamber p to the other end thereof to make the first water delivery channel <NUM> pump water and the second water delivery channel <NUM> deliver water.

Optionally, the flexible pump core <NUM> may be entirely made of the deformable material. By changing the thickness of the deformable material, the flexible pump core <NUM> may be partially supported. For example, the flexible pump core <NUM> has thicker upper and lower surfaces, which may support the flexible pump core <NUM> and thus the flexible pump core <NUM> has certain shape. The flexible pump core <NUM> has a relatively thin middle portion which may be subjected to certain deformation by squeezing and may basically return to its original shape when the squeezing force is removed. Preferably, the flexible pump core <NUM> is made of rubber. As such, the flexible pump core <NUM> is subjected to certain deformation when being squeezed and the chamber p has a good sealing property to prevent water leakage. In some embodiments, the flexible pump core <NUM> may also be made of other deformable materials, such as silica gel, as long as the flexible pump core <NUM> may be subjected to certain deformation when being squeezed and the chamber p has good sealing property.

It may be understood that the interior of the flexible pump core <NUM> may be partially made of the deformable material and deformed by squeezing or entirely made of the deformable material and deformed by squeezing as long as a portion, in contact with the squeezing device <NUM>, of the flexible pump core <NUM> is made of the deformable material, and may be deformed by squeezing.

Optionally, the outer bracket <NUM> may be entirely made of a hard material, partially made of a hard material and partially made of a deformable material, or entirely made of a deformable material with a low deformation degree as long as the outer bracket <NUM> plays a role of supporting when sleeving the flexible pump core <NUM>, and defines, together with the flexible pump core <NUM>, the chamber p.

With continued reference to <FIG> and <FIG>, the first water delivery channel <NUM> and the second water delivery channel <NUM> are disposed on the outer bracket <NUM>, and the two opposites ends of the chamber p are communicated with the first water delivery channel <NUM> and the second water delivery channel <NUM> respectively. The first water delivery channel <NUM> is connected with the liquid storage device. A wall surface of the chamber p is at least partially made of the deformable material. The squeezing device <NUM> periodically squeezes the deformable material from one end of the chamber p to the other end thereof to make the first water delivery channel <NUM> pump water and the second water delivery channel <NUM> deliver water.

With reference to <FIG>, <FIG>, the water pumping device <NUM> further comprises an inner bracket <NUM> (as shown in <FIG>). The inner bracket <NUM> is fixed inside the flexible pump core <NUM> (as shown in <FIG>) and is made of a hard material. The squeezing device <NUM> drives the inner bracket <NUM> to periodically squeeze the flexible pump core <NUM> from one end of the chamber p to the other end thereof to make the first water delivery channel <NUM> pump water and the second water delivery channel <NUM> deliver water. During moving, the squeezing device <NUM> is not in direct contact with the flexible pump core <NUM>, but it squeezes the flexible pump core <NUM> by driving the inner bracket <NUM>, so that the wear of the flexible pump core <NUM> can be reduced. In addition, as the flexible pump core <NUM> is squeezed by the inner bracket <NUM>, the squeezing contact surface is increased. As such, the efficiency of squeezing the flexible pump core by the squeezing device <NUM> can be improved, the load can be reduced, and thus the liquid is delivered more uniformly.

With reference to <FIG>, the arrow indicates a movement direction of the squeezing device <NUM>. When the water pumping device <NUM> is in a working state, the squeezing device <NUM> drives the inner bracket <NUM> to squeeze the flexible pump core <NUM> from one end of the chamber p to the other end thereof so as to divide the chamber p into a water inlet chamber p1 and a water outlet chamber p2. The water inlet chamber p1 is located on a back side in the movement direction of the squeezing device <NUM> and the water outlet chamber p2 is located on a front side in the movement direction of the squeezing device <NUM>. It may be understood that when the squeezing device <NUM> continues to move from the state shown in <FIG>, the water inlet chamber p1 will generate negative pressure and the liquid is pumped into the water inlet chamber p1 from the first water delivery channel <NUM>. At the same time, the water outlet chamber p2 will generate positive pressure and the liquid in the water outlet chamber p2 is discharged from the second water delivery channel <NUM>. When the squeezing device <NUM> moves to the state shown in <FIG>, the liquid in the water outlet chamber p2 is discharged. There is no hose structure between the first water delivery channel <NUM> and the second water delivery channel <NUM>. Since the chamber does not need to be additionally provided with a hose to contain the liquid, the number of components is reduced and the overall structure is simplified. Thus, the water pumping device <NUM> is simpler in structure.

With reference to <FIG>, <FIG>, the water pumping device <NUM> further comprises an upper cover <NUM> with a first convex member <NUM> (as shown in <FIG>) and a lower cover <NUM> with a second convex member <NUM> (as shown in <FIG>). The flexible pump core <NUM> is provided with a first concave member <NUM> and a second concave member <NUM> (as shown in <FIG>). The first convex member <NUM> matches the first concave member <NUM> in structure and the second convex member <NUM> matches the second concave member <NUM> in structure. When the upper cover <NUM> is connected with the outer bracket <NUM>, the first convex member <NUM> squeezes the first concave member <NUM>, so that the first concave member <NUM> is tightly attached to the outer bracket <NUM>. When the lower cover <NUM> is connected with the outer bracket <NUM>, the second convex member <NUM> squeezes the second concave member <NUM>, so that the second concave member <NUM> is tightly attached to the outer bracket <NUM>. As such, the chamber p has good sealing property to prevent liquid leakage.

With reference to <FIG>, a first water delivery pipe <NUM> is disposed on the upper cover <NUM> and a second water delivery pipe <NUM> is disposed on the lower cover <NUM>. The flexible pump core <NUM> is provided with water delivery holes <NUM> in positions corresponding to the first water delivery channel <NUM> and the second water delivery channel <NUM>.

A first groove <NUM> and a first boss <NUM> that match each other are disposed on surfaces, facing each other, of the outer bracket <NUM> and the upper cover <NUM> respectively (as shown in <FIG>). When the first boss <NUM> is inserted into the first groove <NUM>, the first water delivery pipe <NUM> is correspondingly communicated with the first water delivery channel <NUM> through the water delivery hole <NUM>. A second groove <NUM> and a second boss <NUM> that match each other are disposed on surfaces, facing each other, of the outer bracket <NUM> and the lower cover <NUM> respectively (as shown in <FIG>). When the second boss <NUM> is inserted into the second groove <NUM>, the second water delivery pipe <NUM> is correspondingly communicated with the second water delivery channel <NUM> through the water delivery hole <NUM>.

Optionally, one of the first groove <NUM> and the first boss <NUM> is disposed on the outer bracket <NUM> and the other is disposed on the upper cover <NUM>. One of the second groove <NUM> and the second boss <NUM> is disposed on the outer bracket <NUM> and the other is disposed on the lower cover <NUM>.

It may be understood that by butting the first water delivery pipe <NUM> and the first water delivery channel <NUM>, and butting the second water delivery pipe <NUM> and the second water delivery channel <NUM>, an outlet and an inlet of the liquid are exposed. Therefore, the device may be used by directly connecting water pipes with the first water delivery pipe <NUM> and the second water delivery pipe <NUM> and it is convenient to pump water into the water pumping device <NUM> from the liquid storage device and introduce the liquid into other devices after the liquid is delivered out of the water pumping device <NUM>. In addition, as the first groove <NUM> and the first boss <NUM> as well as the second groove <NUM> and the second boss <NUM> are disposed, when the outer bracket <NUM> is connected with the upper cover <NUM> and the lower cover <NUM>, it is convenient to accurately butt the first water delivery pipe <NUM> and the first water delivery channel <NUM> and butt the second water delivery pipe <NUM> and the second water delivery channel <NUM>, thereby preventing water leakage caused by inaccurate butting. In addition, the rigidity of the outer bracket <NUM> can be limited, and shaking due to a squeezing force of the squeezing device <NUM> and the outer bracket <NUM> is avoided during working, thereby improving the stability of delivering the liquid. The fixing of the outer bracket <NUM> ensures the forming of the flexible pump core <NUM>, thereby improving the liquid delivery effect.

With reference to <FIG> and <FIG>, the squeezing device <NUM> comprises an eccentric wheel <NUM>, a swing bearing <NUM>, a motor <NUM> and a reduction gear assembly <NUM>. The motor <NUM> and the eccentric wheel <NUM> are connected through the reduction gear assembly <NUM>. When rotating, the motor <NUM> decelerates through the reduction gear assembly <NUM>, so that the movement speed of the eccentric wheel <NUM> matches the optimal water outlet frequency. The swing bearing <NUM> is disposed on the eccentric wheel <NUM>, and is tightly attached to the deformable material. The motor <NUM> rotates to drive, through the reduction gear assembly <NUM>, the eccentric wheel <NUM> to move, and thus drive the swing bearing <NUM> to periodically squeeze the deformable material from one end of the chamber p to the other end thereof to make the first water delivery channel <NUM> pump water and the second water delivery channel <NUM> deliver water. Since the swing bearing <NUM> is tightly attached to the deformable material, the swing bearing <NUM> is driven through the eccentric wheel <NUM> during squeezing and there is less friction between the swing bearing <NUM> and the deformable material, which can reduce the wear of the deformable material and prolongs the service life of the water pumping device <NUM>.

With continued reference to <FIG>, the squeezing device <NUM> further comprises a driving shaft <NUM>, a driven shaft <NUM> and a sealing member <NUM>. The driving shaft <NUM> is connected with the reduction gear assembly <NUM>, the driven shaft <NUM> is connected with the driving shaft <NUM> and the eccentric wheel <NUM>, and the sealing member <NUM> is disposed between the driving shaft <NUM> and the driven shaft <NUM>. As a result, the eccentric wheel <NUM> may be separated from the reduction gear assembly <NUM> without affecting the movement of the eccentric wheel <NUM> to achieve the effect of water and electricity separation and improve the use safety of the water pumping device <NUM>.

With reference to <FIG>, an accommodating groove q is formed in the lower cover <NUM> and the motor <NUM> is accommodated in this accommodating groove q. As such, a fixing effect is achieved when the motor rotates <NUM>, and thus the liquid return caused by shaking of the motor <NUM> is avoided.

As a modified embodiment, the first water delivery channel <NUM> and the second water delivery channel <NUM> may be disposed on the flexible pump core <NUM>, or one of the first water delivery channel <NUM> and the second water delivery channel <NUM> is disposed on the flexible pump core <NUM> and the other is disposed on the outer bracket <NUM> as long as the first water delivery channel <NUM> is connected with the liquid storage device and the two opposite ends of the chamber p are communicated with the first water delivery channel <NUM> and the second water delivery channel <NUM> respectively.

In some modified embodiments, the flexible pump core <NUM> may be provided with no water delivery hole <NUM>. The first water delivery pipe <NUM> directly corresponds to the first water delivery channel <NUM> and the second water delivery pipe <NUM> directly corresponds to the second water delivery channel <NUM> as long as the first water delivery pipe <NUM> is correspondingly communicated with the first water delivery channel <NUM> when the first boss <NUM> is inserted into the first groove <NUM>, and the second water delivery pipe <NUM> is correspondingly communicated with the second water delivery channel <NUM> when the second boss <NUM> is inserted into the second groove <NUM>.

In some modified embodiments, the first boss <NUM> may also be disposed on an edge of the surface, facing the outer bracket <NUM>, of the upper cover <NUM>, and at the same time, the first groove <NUM> is formed in a corresponding position of the surface, facing the upper cover <NUM>, of the outer bracket <NUM>, so that when the upper cover <NUM> is connected with the outer bracket <NUM>, the first boss <NUM> is just inserted into the first groove <NUM>; or the first groove <NUM> is formed in a corresponding position of the periphery of the outer bracket <NUM>, so that when the upper cover <NUM> is connected with the outer bracket <NUM>, the first boss <NUM> is just clamped in the first groove <NUM>. By the same reason, the second boss <NUM> may also be disposed on an edge of the surface, facing the outer bracket <NUM>, of the lower cover <NUM>, and at the same time, the second groove <NUM> is formed in a corresponding position of the surface, facing the lower cover <NUM>, of the outer bracket <NUM>, so that when the lower cover <NUM> is connected with the outer bracket <NUM>, the second boss <NUM> is just inserted into the second groove <NUM>; or the second groove <NUM> is formed in a corresponding position of the periphery of the outer bracket <NUM>, so that when the lower cover <NUM> is connected with the outer bracket <NUM>, the second boss <NUM> is just clamped in the second groove <NUM>.

Optionally, the outer bracket <NUM> is connected with the upper cover <NUM> and the lower cover <NUM> by any of magnetic attraction, clamping and threaded connection. The connection mode of the outer bracket <NUM> with the upper cover <NUM> and the lower cover <NUM> is not limited as long as the outer bracket <NUM> may be tightly connected with the upper cover <NUM> and the lower cover <NUM> and the disassembly is convenient for facilitating cleaning and maintenance of the internal structure of the water pumping device <NUM>.

With reference to <FIG>, a first example of liquid storage device <NUM> for supplying a liquid to an external device (such as a hairdressing device, a humidifier, and a face-cleaning device). The liquid storage device <NUM> comprises a tank <NUM>, a water guide pipe <NUM>, and a first water suction member <NUM>. A portion of the water guide pipe <NUM> and the first water suction member <NUM> are embedded into the tank <NUM>, and the first water suction member <NUM> is communicated with the water guide pipe <NUM>. As an embodiment, a communication mode of the first water suction member <NUM> and the water guide pipe <NUM> is specifically that one end of the first water suction member <NUM> is placed in the water guide pipe <NUM> and an opposite end of the first water suction member <NUM> extends to a wall surface, away from the water guide pipe <NUM>, in the tank <NUM>. The water guide pipe <NUM> runs through the tank <NUM> and is partially exposed to the tank <NUM>. The water guide pipe <NUM> is configured to output the liquid to the external device, the tank <NUM> is configured to store the liquid, and the first water suction member <NUM> is configured to suck the liquid in the tank <NUM> and output the liquid to the outside through the water guide pipe <NUM>.

It may be understood that the water guide pipe <NUM> may be connected with a water pump, through which the liquid in the tank <NUM> is discharged. For example, in a steam hair-straightening device, the liquid in the tank <NUM> is pumped out through a peristaltic pump.

It may be understood that the water guide pipe <NUM> is in interference fit with the first water suction member <NUM>, so that a connection position of the water guide pipe <NUM> and the first water suction member <NUM> is sealed, thereby avoiding the failure of pumping water due to loose connection and improving the stability of pumping water.

Specifically, the tank <NUM> comprises a first housing <NUM> and a second housing <NUM>. The first housing <NUM> is buckled on the second housing <NUM>. There is an accommodating space between the first housing <NUM> and the second housing <NUM>. The first water suction member <NUM> and a portion of the water guide pipe <NUM> are disposed in this accommodating space. This accommodating space is configured to store the liquid. A water outlet <NUM> is formed in the second housing <NUM>. The water guide pipe <NUM> runs through the second housing <NUM> through the water outlet <NUM> so as to output the liquid in the tank <NUM> to the external device. Particularly, after the first water suction member <NUM> sucks the liquid, an end, away from the water guide pipe <NUM>, of the first water suction member <NUM> has an increased weight due to liquid suction and may move in the tank <NUM>. When there is little liquid in the tank <NUM>, the end, away from the water guide pipe <NUM>, of the first water suction member <NUM> may move to a liquid position to suck the liquid and then output the liquid to the water guide pipe <NUM>.

It may be understood that the water guide pipe <NUM> and the first water suction member <NUM> are disposed in the accommodating space of the tank <NUM>, the first water suction member <NUM> is in contact with the liquid in the tank <NUM>, and the liquid in the tank <NUM> may enter the external device through the water guide pipe <NUM>. The first water suction member <NUM> sucks the liquid in the tank <NUM> and the external device draws the liquid from the liquid storage device <NUM>. As the air pressure outside the tank <NUM> is less than the air pressure inside the tank, the first water suction member <NUM> delivers the liquid in the tank <NUM> to the external device through the water guide pipe <NUM> by means of a wicking effect.

Optionally, a load block <NUM> is disposed at the end, away from the water guide pipe <NUM>, of the first water suction member <NUM>, so that when the tank <NUM> is in a holding state, the end of the first water suction member <NUM> with the load block <NUM> may move in the tank <NUM> to the position where the liquid is located in the tank <NUM>. Thus, it is ensured that the first water suction member <NUM> may output liquid.

With continued reference to <FIG>, at least one first through hole <NUM> is formed in the water guide pipe <NUM> at a position corresponding to the first water suction member <NUM>, and a position, corresponding to the first through hole <NUM>, of the first water suction member <NUM> is exposed to the first through hole <NUM>. It may be understood that by forming the first through hole <NUM> in the water guide pipe <NUM>, the liquid at the position, where the water guide pipe <NUM> is located, in the tank <NUM> may be in contact with the first water suction member <NUM>. When there is ;little liquid stored in the tank <NUM>, the liquid may be accumulated at the position where the water guide pipe is located by reversing the tank <NUM> and then is sucked by the first water suction member <NUM> at the through hole <NUM>, thereby improving the utilization rate of the liquid of the liquid storage device <NUM>. Further, the position, corresponding to the first through hole <NUM>, of the first water suction member <NUM> is exposed to be in contact with the liquid, a contact surface between the first water suction member <NUM> and the liquid is increased and the water suction area of the first water suction member <NUM> is increased. Thus, the suction and utilization rate of the liquid of the liquid storage device <NUM> is increased.

Optionally, the water guide pipe <NUM> is made of a flexible material, so that the water guide pipe <NUM> may be elastically deformed at the position of the first through hole <NUM>, that is, the first through hole <NUM> may be deformed to increase the movement range of the first water suction member <NUM>. The end, away from the water guide pipe <NUM>, of the water suction member <NUM> may move to more positions in the tank <NUM> to suck the liquid, thereby increasing the utilization rate of the liquid in the tank <NUM>.

Optionally, the first through hole <NUM> is in interference fit with the first water suction member <NUM> to maintain the sealing therebetween and thus prevent the failure of water suction due to air leakage by the first through hole <NUM>.

With continued reference to <FIG>, the first housing <NUM> comprises a water injection hole <NUM>, a cover <NUM>, a barrier <NUM>, and a vent hole <NUM>. The water injection hole <NUM> and the vent hole <NUM> run through the first housing <NUM>. The cover <NUM> matches the water injection hole <NUM> and covers the water injection hole <NUM>. The barrier <NUM> runs through the first housing <NUM>. The cover <NUM> is configured to block the water injection hole <NUM> during use. The water injection hole <NUM> is configured for injection of the liquid into the tank <NUM>. The vent hole <NUM> is configured to keep the air pressure in the tank <NUM> balanced. The barrier <NUM> is configured to block the vent hole <NUM>.

Specifically, a user may inject the liquid into the tank <NUM> through the water injection hole <NUM> and the cover <NUM> may seal the water injection hole <NUM>, so that the tank <NUM> filled with the liquid keeps a sealed state. The vent hole <NUM> may keep the air pressure inside and outside the tank <NUM> balanced. The barrier <NUM> may block the vent hole <NUM> to prevent the liquid from leaking from the vent hole <NUM>.

With reference to <FIG> and <FIG>, an auxiliary water suction assembly <NUM> is disposed on a side, close to the water outlet <NUM>, of the water guide pipe <NUM>. The auxiliary water suction assembly <NUM> extends in a direction away from the water guide pipe <NUM> and is configured to suck the liquid, close to the water outlet <NUM>, in the tank <NUM>.

Specifically, the auxiliary water suction assembly <NUM> is disposed at a position, close to the water outlet <NUM>, of the tank <NUM> so as to suck the liquid at the water outlet <NUM> in the tank <NUM>. It may be understood that when there is little liquid in the tank <NUM>, the auxiliary water suction assembly <NUM> may normally provide the liquid while the first water suction member <NUM> of the liquid storage device <NUM> provides little liquid, thereby increasing the liquid utilization rate of the liquid storage device <NUM>.

With continued reference to <FIG> and <FIG>, the auxiliary water suction assembly <NUM> comprises an auxiliary water suction pipe <NUM> and a second water suction member <NUM>. The auxiliary water suction pipe <NUM> is disposed on the side, close to the water outlet <NUM>, of the water guide pipe <NUM>, extends towards the direction away from the water guide pipe <NUM> and is communicated with the water guide pipe <NUM>. At least one second through hole <NUM> is formed in the auxiliary water suction pipe <NUM>. The auxiliary water suction pipe <NUM> is configured to deliver liquid sucked by the second water suction member <NUM>. The second water suction member <NUM> is configured to suck the liquid close to the water outlet <NUM> in the tank <NUM>. The second through hole <NUM> is configured to increase the contact surface between the second water suction member <NUM> and the liquid.

Specifically, the second water suction pipe <NUM> is embedded into the auxiliary water suction pipe <NUM> and has a length greater than that of the auxiliary water suction pipe <NUM>, so that one end of the second water suction member <NUM> is exposed to the auxiliary water suction pipe <NUM>. The auxiliary water suction pipe <NUM> has one end connected with a pipe body of the water guide pipe <NUM> and an opposite end thereof extending towards the inner surface of the tank <NUM>. The end, away from the water guide pipe <NUM>, of the second water suction member <NUM> sucks the liquid and delivers the liquid to the water guide pipe <NUM>, so that the liquid at the position where the second water suction member <NUM> is away from the water outlet <NUM>, in the tank is used. By forming the second through hole <NUM> in the auxiliary water suction pipe <NUM>, the contact area of the second water suction member <NUM> and the liquid is increased and the liquid, at the position of the auxiliary water suction pipe <NUM>, in the tank <NUM> is sucked by the second water suction member <NUM>. Thus, the utilization rate of the liquid in the tank <NUM> is increased. Of course, the second water suction member <NUM> may have a length less than or equal to that of the auxiliary water suction pipe <NUM> as long as the second water suction member <NUM> may be placed in the auxiliary water suction pipe <NUM> and sucks water.

Optionally, the first water suction member <NUM> and the second water suction member <NUM> may be a cotton stick or other materials having a wicking effect.

Optionally, there may be one, two, three or more than three second through holes <NUM> as long as the second water suction member <NUM> may pass through the second through hole <NUM> to contact the liquid. In this embodiment, the number of the second through hole <NUM> is one, but is not limited in this embodiment.

Optionally, the auxiliary water suction pipe <NUM> extends to the inner surface of the tank <NUM> to increase the utilization rate of the liquid in the tank <NUM>.

Optionally, the water guile pipe <NUM> adopts the structure of a T-shaped three-way pipe. It may be understood that the auxiliary water suction pipe <NUM> and the water guide pipe <NUM> are vertically disposed.

Optionally, the auxiliary water suction pipe <NUM> and the wall surface of the end, close to the water outlet <NUM>, the tank <NUM> have the same size, which can increase the utilization rate of the liquid at a lower water level.

With reference to <FIG> and <FIG>, a second example of liquid storage device <NUM>' which differs from the first example in that an auxiliary water suction assembly <NUM>' comprises a water suction block <NUM>' and a drainage member <NUM>'. The water suction block <NUM>' is disposed on a side, close to the inner surface of a tank <NUM>', of the drainage member <NUM>'. The drainage member <NUM>' is communicated with a water guide pipe <NUM>'. The drainage member <NUM>' comprises at least one drainage port <NUM>' communicated with the water guide pipe <NUM>'. The water suction block <NUM>' is disposed on the drainage port <NUM>'. The water suction block <NUM>' is configured to suck the liquid in the tank <NUM>' and discharge the liquid through the drainage member <NUM>'. The drainage member <NUM>' is configured to discharge the liquid close to a water outlet <NUM>' in the tank <NUM>'.

Specifically, the drainage member <NUM>' is provided with a drainage port <NUM>' on the side close to the surface of the tank <NUM>'. The water suction block <NUM>' is in contact with the inner surface of the tank <NUM>' and is in interference connection with the drainage port <NUM>'. The water suction block <NUM>' sucks liquid close to the water outlet <NUM>', in the tank <NUM>' and discharges the liquid through the drainage member <NUM>', so that the liquid close to the water outlet <NUM>' in the tank <NUM>' is sucked by the water suction block <NUM>', thereby increasing the utilization rate of the liquid in the tank <NUM>'. Preferably, the water suction block <NUM>' may be any of water suction materials such as a cotton stick and sponge.

Optionally, the water guide pipe <NUM>' comprises a compression portion <NUM>' and a connection portion <NUM>'. The connection portion <NUM>' is connected with one end of the first water suction member <NUM>' and the compression portion <NUM>' is compressible. The first water suction member <NUM>' approaches the water guide pipe <NUM>' by compressing the compression portion <NUM>', so that the liquid, close to the water guide pipe <NUM>', in the tank <NUM>' is sucked by the first water suction member <NUM>' and is delivered to the external device. Further, the first water suction member <NUM>' compresses the compression portion <NUM>' to move in the tank <NUM>', thereby increasing the movement range of the first water suction member <NUM>'.

Optionally, there may be one, two, three or more than three drainage ports <NUM>' as long as the water suction block <NUM>' may pass through the drainage port <NUM>' to contact the liquid. In this embodiment, the number of the drainage port <NUM>' is one, but is not limited in this embodiment.

It may be understood that the water suction block <NUM>' is in interference fit with the drainage member <NUM>', so that a connection position of the water suction block <NUM>' and the drainage member <NUM>' is sealed, thereby avoiding the failure of pumping water due to loose connection and improving the stability of pumping water.

With reference to <FIG> and <FIG>, a third example of liquid storage device <NUM>" which differs from the first example in that: an auxiliary water suction assembly <NUM>" comprises a water flow pipe <NUM>", a fixed pipe <NUM>" and a second water suction member <NUM>". The water flow pipe <NUM>" is positioned on a pipe body of the fixed pipe <NUM>", and a water guide pipe <NUM>", the water flow pipe <NUM>" and the fixed pipe <NUM>" are sequentially disposed and communicated to form a structure of an H-shaped four-way pipe. The second water suction member <NUM>" is embedded into the fixed pipe <NUM>". At least one second through hole <NUM>" is formed in the fixed pipe <NUM>". Preferably, the second through hole <NUM>" is formed in the side, away from the water flow pipe <NUM>", of the fixed pipe <NUM>".

Specifically, two ends the fixed pipe <NUM>" are open. The second water suction member <NUM>" is embedded into the fixed pipe <NUM>" and may be in contact with liquid through two ends exposed to the fixed pipe <NUM>". As such, the liquid at the position of the fixed pipe <NUM>" is further utilized. At the same time, the user may tilt the liquid in a tank <NUM>" towards this position, so that the second water suction member <NUM>" may suck the liquid. Furthermore, the second through hole <NUM>" is formed in the fixed pipe <NUM>" to increase the contact area between the second water suction member <NUM>" and the liquid, thereby increasing the utilization rate of the liquid.

It may be understood that the second water suction member <NUM>" may have a length less than, greater than or equal to the length of the fixed pipe <NUM>" as long as the second water suction member <NUM>" is fixed in the fixed pipe <NUM>" and sucks water.

Optionally, there may be one, two, three or more than three second through holes <NUM>" as long as the second water suction member <NUM>" may pass through the second through hole <NUM> to contact the liquid. In this embodiment, the number of the through hole <NUM>" is one, but is not limited in this embodiment.

It may be understood that the fixed pipe <NUM>" is in interference fit with the second water suction member <NUM>", so that a connection position of the fixed pipe <NUM>" and the second water suction member <NUM>" is sealed, thereby avoiding the failure of pumping water due to loose connection and improving the stability of pumping water. The second through hole <NUM>" is in interference fit with the second water suction member <NUM>" to maintain the sealing therebetween and prevent the failure of water suction due to air leakage by the second through hole <NUM>".

With reference to <FIG>, an embodiment of the present invention provides a hairdressing device <NUM>. The hairdressing device <NUM> may comprise the water pumping device <NUM> and the liquid storage device <NUM> according to the present invention. The liquid storage device <NUM> is connected with the water pumping device <NUM>. The hairdressing device <NUM> may be configured to straighten hair, curl hair, dye hair and nourish hair, which is not specifically limited in the embodiment of the present invention. Specifically, the chamber p has a volume of <NUM>-<NUM>, the squeezing device has a squeezing speed of <NUM>-<NUM> r/min to the chamber and the water pumping device <NUM> works at this volume and the squeezing speed, which can make the amount of liquid delivered from the water pumping device <NUM> and the liquid delivery frequency suitable for the hairdressing device <NUM>, without negatively affecting hairdressing of the hairdressing device <NUM> due to too little or too much liquid delivered.

It may be understood that when being used, the hairdressing device <NUM> usually needs to be held and used at many angles (for example, a portable steam hair straightener needs to be lifted to meet the requirements of straightening hair at various angles). As a result, the liquid storage device <NUM> in the device also needs to subject to angle change, and the liquid in the liquid storage device <NUM> will move to different positions. When the liquid moves close to the water outlet, the liquid may be continued to be sucked through the liquid storage device <NUM>. Thus, the utilization rate of the liquid is increased and the failure of water suction due to liquid inversion is avoided.

As an embodiment, with reference to <FIG> which shows a steam hair straightener <NUM> deformed from the hairdressing device <NUM>. The steam hair straightener <NUM> comprises an atomization device <NUM>. Liquid delivered from the second water delivery pipe of the water pumping device <NUM> passes through the atomization device <NUM> to form steam.
