BACKGROUND

Skin care has become a part of people's daily life. Beauty and makeup include many things, such as hair extensions, eyelash grafting, etc., which all require adhesives. Many adhesives cannot be used in one time. In order to avoid invalidation or partial solidification, the remaining adhesive needs to be dried as soon as possible to facilitate the subsequent storage and prolong the service life of the adhesive. However, since there will be a certain amount of moisture in air, after a long period of storage, the adhesive will inevitably regain moisture, which will seriously affect the use of the adhesive and even damage the adhesive. Therefore, such items need to be stored in vacuum drying equipment after use.

In addition to application in the field of beauty, the above vacuum drying equipment is often used in daily life, such, as storing snacks that need to be stored in a dried state. At this time, food need to be dried before storage, but the vacuum drying devices on the market generally have the technical problems of “large volume, inconvenience in carrying, and low drying efficiency”, so a small-volume drying device is urgently required to solve the above-mentioned technical problems.

It should be noted that non-conflicting embodiments in the disclosure and the features in the embodiments may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a full understanding of the disclosure. The disclosure may be practiced otherwise than as described herein. The following specific embodiments are not to limit the scope of the disclosure.

Unless defined otherwise, all technical and scientific terms herein have the same meaning as used in the field of the art as generally understood. The terms used, in the disclosure are to describe particular embodiments and are not intended to limit the disclosure.

As shown inFIG.1toFIG.5, the present disclosure discloses a vacuum drying tank, including a shell1and a pumping device2. The shell1includes a first shell, part11, a second shell part12, and a third shell part13; the second shell part12is internally hollowed; the second shell part12has an opening in the top and is provided with a bottom end surface at the bottom; a hollow cavity inside the second shell part12and the bottom end surface form an accommodating cavity120used for storing an object; and an air pumping hole121is formed in the bottom end surface of the accommodating cavity120. As a preference, the first shell part11is hemispherical and has a certain space inside. When the first shell part11is hermetically buckled to the second shell part12, the internal space of the first shell part11and the accommodating cavity120form a larger storage space122so as to further enlarge a storage space for the object. The third shell part13is arranged below the second shell part12. The pumping device2is arranged in the third shell part13and is communicated with the air pumping hole121. The pumping device2is used for pumping out air in the storage space122through the air pumping hole121, so that the storage space122is in a vacuum state. Specifically, in this embodiment, the vacuum drying tank is further provided with an air guide pipe21. One end of the air guide pipe21is communicated to the pumping device2, and the other end is communicated to the air pumping hole121.

During use of the equipment, the first shell part11is first opened. An object is stored in the accommodating cavity120through the opening in the top of the second shell part12. The first shell part11is covered at the top of the second shell part12. The first shell part11and the second shell part12can be fastened through a thread, a fastener, or in a nested manner so as to ensure sealing. After the above steps are completed, the pumping device2is turned on to generate a pumping force. Under the action of the pumping device2, the air in the storage space122is pumped out via the air pumping hole121and the air guide pipe21so as to form a vacuum state, thus bringing away water marks on a product and water vapor in the air to achieve a vacuum drying state. Therefore, by means of the above structural setting, in the present disclosure, a tank body can be set, according to a market requirement, to be smaller so as to facilitate carrying. Compared with drying equipment which has a large volume and a large drying space, the vacuum tank of the present disclosure has higher drying efficiency due to the smaller storage space122, is helpful to save energy, is more environmentally-friendly, and is easy to operate and convenient to use.

When the object needs to be taken out of the tank body of the vacuum tank after use, it is difficult to separate the first shell part11from the second shell part12due to a negative pressure state in the storage space122. In order to solve this technical problem, as shown inFIG.4andFIG.5the present disclosure further includes a button3. The button3is transversely slidably arranged between the second shell part12and the third-shell part13and slides between a first position and a second position. The bottom end surface of the accommodating cavity120is provided with a through hole123and a sealing member124; and the through hole123penetrates through the bottom end surface of the accommodating cavity120so as to communicate the storage space122with external air. Specifically, the through hole123is communicated to the outside through a gap at a joint of the second shell part12and the third shell part13.

When the button3is located at the first position, the sealing member124is clung to the through hole123to close the through hole123; when the button3is pressed to move to the second position, the button3applies a transverse force to the sealing member124, so that the sealing member124is extruded by the button3to deform to open the through hole123, so as to communicate the storage space122to the external air.

By the above structural setting, when an object is stored in the vacuum tank, the button3is located at the first position. At this time, the through hole123is closed by the sealing member124so as to maintain a sealed state of the storage space122. When the vacuum tank needs to be opened, only a transverse acting force is applied to the button3to enable the button to move from the first position to the second position. At this time, the sealing member124is extruded by the button3to deform to open the through hole123, so that the storage space122is communicated to the external air, thus relieving the vacuum state in the storage space122.

As shown inFIG.5toFIG.12, the sealing member124includes a first large-diameter part1241, a second large-diameter part1242, and a small-diameter part1243; the small-diameter part1243is arranged between the first large-diameter part1241and the second large-diameter part1242; a diameter length of the first large-diameter part1241and a diameter length of the second large-diameter part1242are both greater than that of the small-diameter part1243; and the diameter length of the second large-diameter part1242is greater than that of the first large-diameter part1241.

The bottom end surface of the accommodating cavity120is further provided with a mounting opening125. The mounting opening125penetrates through the bottom end surface of the accommodating cavity120. The sealing member124is snapped in the mounting opening125.

The first large-diameter part1241is arranged above the bottom end surface of the accommodating cavity120. The first large-diameter part1241does not shield the through hole123. The second large-diameter part1242is arranged below the bottom end surface of the accommodating cavity120so as to fix the sealing member124on the bottom, end surface of the accommodating cavity120. The second large-diameter part1242is clung to the bottom of the bottom end surface of the accommodating cavity120, thus shielding the through hole123to close the through hole123.

In order to ensure that the second large-diameter part1242is clung to the through hole123, the present disclosure further includes a first elastic member4. One end of the first elastic member4is connected to the shell1, and the other end is pressed against the second large-diameter part1242to apply an acting force that faces the through hole123to the second large-diameter part1242so as to enable the second, large-diameter part1242to be clung to the through hole123.

The first elastic member4of the present disclosure is a torsional spring; one end of the torsional spring is fixed below the bottom end surface of the accommodating cavity120, and the other end has a circling part41; the circling part41is of a spiral structure, an outer diameter of which gradually increases from bottom to top; and the top of the circling part41is pressed against the second large-diameter part1242.

By the above structure, the circling part41always applies an acting force that faces the bottom end surface of the accommodating, cavity120to the second large-diameter part1242to further ensure that the second large-diameter part1242is clung to the through hole123. In addition, the circling part41is of the spiral structure, the outer diameter of which gradually increases from bottom to top, so that the outer diameter of its top end is the largest. The top end resists against the second large-diameter part1242, which enlarges a contact area between the circling part41and the second large-diameter part1242, thus further enhancing the closing effect.

In this embodiment, the first elastic member4may also be other elastic member having the above function. For example, the first elastic member4may also be a clip. One end of the clip is fixed to the shell1, and the other end of the clip has an arc convex surface. The arc convex surface is pressed against the second large-diameter part1242.

After the vacuum state of the storage space122is relieved, the button3is required to be reset from the second position back to the first position so as to recover the leakproofness of the storage space122for next use. Therefore, an acting force for resilience is required to be applied to the button3.

In order to solve the above technical problems, as shown inFIG.7,FIG.8,FIG.10,FIG.11, andFIG.12, the vacuum drying tank of the present disclosure further includes a second elastic member5.

A front end of the sliding part31is further provided with an extrusion sharp end33; the extrusion sharp end33is an inverted triangle with a narrow front part and a rear wide part; and when the button3is located at the second position, the extrusion sharp end33extrudes the second large-diameter part1242so as to open the through hole123.

By the above structural setting, when the button3is located at the first position, the second elastic member5is fixed between the first positioning column61and the second positioning column62, and at this time, the second elastic member5is in the natural non-stressed state; and when the button3is slightly pushed with a finger to move to the second position under a force, the sliding part31slides in the first sliding slot321, so as to drive the second positioning column62to be away from the first positioning column61, thus driving the second elastic member5to extend. At this time, the extrusion sharp end33extrudes the second large-diameter part1242to open the through hole123. After the finger leaves the button, the extended second elastic member5rebounds, thus driving the sliding part31to return to the first position.
