DETAILED DESCRIPTION
To make the object, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be described below in a clearer and more complete way with reference to the figures of the embodiments of the present invention. Apparently, the embodiments described are only part, rather than all of the embodiments of the present invention. Based on the embodiments of the present invention described, all the other embodiments obtained by a person of ordinary skills in the art without paying inventive work fall into the scope of protection of the present invention.
As illustrated in FIGS. 1, 2 and 4, the spray head provided by the embodiments of the present invention comprises: a spray head body 1 comprising a panel provided with spray holes 5, the panel being provided with a plurality of brush rods 2, a chamber 4 being formed in the spray head body 1, the chamber being in communication with the spray holes 5. Each brush rod 2 has a spheroid 3 at its end portion that faces away from the spray head body 1, and the spheroid 3 is made of an elastic material.
During use of the above spray head, the brush rods 2 provided on the spray head body 1 can penetrate through a user's hair and the spheroid 3 formed at the end portion of each brush rod 2 can contact the user's scalp, and clean and massage the user's scalp. In addition, the brush rod 2 can serve as a comb such that the water sprayed from the spray holes 5 easily enters the hair to fully contact the hair and the scalp, thereby thoroughly cleaning the hair, scalp, and the bottom portion of the hair near the scalp.
Therefore, the above spray head, in the course of its use, can penetrate through hair to thoroughly clean the hair, the scalp, and the bottom portion of the hair near the scalp.
In addition, as the brush rod 2 passes through the hair, the spheroid 3 formed at the end of each brush rod 2 can contact a user's scalp and the spheroid 3 made of the elastic material can be deformed to ease the interaction between the scalp and the spray head. Meanwhile, the spheroid 3 can increase the force bearing surface of the scalp so as to alleviate the pressure generated on the scalp and result in a massaging effect on the scalp.
As illustrated in FIG. 1, in one particular embodiment, a plurality of brush rods 2 is distributed uniformly at the edge of the panel, wherein spray holes 5 are provided in the spray head body 1.
As illustrated in FIG. 2, on the basis of the above embodiments, in one particular embodiment, each of the brush rods 2 has a length of 1 cm.
The brush rods 2 with a length of 1 cm can prevent the spray head body 1 from directly contacting the scalp to pressurize the user's scalp as the brush rods 2 penetrate through the hair.
As illustrated in FIG. 2, on the basis of the above embodiments, in a preferred embodiment, the separation distance between each two adjacent brush rods 2 is 0.5 cm; in another preferred embodiment, the separation distance between each two adjacent brush rods is 1 cm and the diameter of the spheroids 3 is 0.5 cm.
On the basis of the above embodiments, in one particular embodiment, the brush rods 2 and the spheroids 3 formed at their end portions are made of the same material, i.e. an elastic material; more preferably, the brush rods 2 and the spheroids formed at their end portions are prepared by a one-piece fabrication process. As illustrated in FIG. 3 and FIG. 5, as the brush rods 2 penetrate through the user's hair and the spheroids 3 at their end portions contact the scalp, the brush rods 2 will be deformed to ease the interaction between the scalp and the spray head, thereby alleviating the pressure produced on user's scalp.
On the basis of each of the above-described embodiments, in one particular embodiment, the elastic material may be a silicone material.
In a preferred embodiment, the silicone material is a phenylene silicone rubber.
Phenylene silicone rubber is a class of silicone rubber formed by introduction of phenylene groups to the polysiloxane backbone. Phenylene silicone rubber exhibits excellent resistance to high temperature and resistance to radiation, capable of resisting a high temperature of up to 250 to 300° C., and has good characteristics such as dielectric properties, moisture resistance, mildew resistance and steam resistance. In the raw rubber composition of the phenylene silicone rubber, it is appropriate when the phenylene content is 60%, the phenyl content is 30%, and the methyl content is 10% (the vinyl content is 0.6%). In this case, the vulcanized rubber exhibits excellent overall performance.
In another preferred embodiment, the silicone material is a phenylene ether silicone rubber.
Phenylene ether silicone rubber is a polysiloxane to whose molecular main chain phenyl ether groups and phenylene groups are introduced. Phenyl ether silicone rubber has good mechanical properties, with its tensile strength generally up to 150 to 180 kg/cm2, i.e. 14.7 to 17.7 Mpa, which is far greater than the strength of vinyl silicone rubber, and an excellent resistance to radiation which is better than that of phenylene silicone rubber. Phenyl ether silicone rubber can be resistant to hot air aging at 250° C. over a long period of time and has high strength even after ageing. Phenylene ether silicone rubber has low temperature performance far superior to phenylene silicone rubber, and has good processing performance useful for manufacturing model articles and extruded products under specific requirements.
As illustrated in FIG. 4 and FIG. 5, on the basis of each of the above-described embodiments, in a specific embodiment, at least part of the brush rods in the plurality of brush rods 2 has a water passage 6; the water inlet of the water passage 6 is in communication with the chamber formed in the spray head body 1 and the water outlet of the water passage 6 is located on the surface of the spheroid 3. Such a design can reduce water sputtering, and without hair barrier, the water flows from the water passage and directly arrives at the scalp surface for cleaning. In a specific embodiment, the water outlet of the water passage is located on the surface of the spheroid in an extension line of the water passage. When the water outlet is located on the surface of the spheroid in the extension line of the water passage, the brush rod will be slightly inclined during use of the spray head, and the water outlet is located near the portion of the spheroid that contacts the scalp, the water flowed from the spheroid can effectively and timely clean the scalp and the bottom portion of the hair near the scalp.
The embodiments of the present invention further provide a body cleaning device, comprising a spray head provided by any of the above technical solutions.
As illustrated in FIG. 6, the above body cleaning device comprises a urine cup 7 connected to a sewage tank 8 provided with a separator 9 thereabove, the separator 9 being connected to the input terminal of a suction motor 10 whose output terminal is connected to a filter 11, one outlet of the filter 11 being connected to the urine cup 7; the other outlet of the filter 11 is connected to one inlet of a manifold and the other inlet of the manifold is connected to the outlet of a hot water system 12; the outlet of the manifold is connected to the urine cup 7. However, the above spray head is connected to the interface part of the water inlet of the urine cup 7.
