[0001] The utility model relates to smearing device technical field, specifically a kind of hydrogel smearing device. BACKGROUND

[0002] As a kind of material with high water absorption and biocompatibility, hydrogel is widely used in medical, cosmetics and food fields. Its excellent physical and chemical properties make it perform well in skin care, wound healing and drug delivery. However, the current market mostly uses manual smearing method to apply hydrogel, which not only is inefficient, but also easily causes waste and uneven smearing of hydrogel.

[0003] The disclosure of the above background art content is only used to assist in understanding the concept and technical solution of the utility model, and it does not necessarily belong to the prior art of the present patent application. In the absence of explicit evidence that the above content has been disclosed on the filing date of the present patent application, the above background art should not be used to evaluate the novelty and inventiveness of the present application. UTILITY MODEL CONTENT

[0004] The present application provides a kind of hydrogel smearing device, which can reduce the waste of hydrogel and increase the uniformity of hydrogel smearing.

[0005] To achieve the above purpose, the present application adopts the following technical solutions:

[0006] A kind of hydrogel smearing device, comprising a hydrogel container and a smearing assembly, the hydrogel container is used to hold hydrogel, and a glue outlet is provided on the hydrogel; the smearing assembly comprises a support plate, an elastic member, a connecting block and a ball, the support plate is arranged inside the hydrogel container, and the support plate is fixedly connected with the inner wall surface of the hydrogel container, a through hole is provided on the support plate, one end of the elastic member is fixedly connected with the support plate, the other end of the elastic member is fixedly connected with the connecting block, the center axis of the through hole and the extension direction of the elastic member are both parallel to the center axis of the glue outlet, a ball running cavity is provided on the surface of the connecting block away from the elastic member, the radius of the ball is greater than the radius of the glue outlet, part of the ball is movably arranged in the ball running cavity, and part of the ball is located outside the glue outlet.

[0007] In the present application embodiment, the user can gently abut the ball at the skin where hydrogel needs to be smeared, so that the connecting block pushes the spring to compress, thereby moving the ball to the inside of the hydrogel smearing device, and then forming a gap between the ball and the glue outlet for the outflow of hydrogel. When the user releases the pressure, the elastic member will rebound due to its own elasticity, and the connecting block and the ball will also return to the initial state, thereby blocking the glue outlet. In addition, when pressing, the ball can move uniformly in the smearing area, thereby forming a uniform coating when contacting the skin surface.

[0008] In this way, automatic and uniform hydrogel coating is achieved, avoiding waste and unevenness in manual coating, improving use efficiency, and enabling users to easily and efficiently coat hydrogel. In addition, the outflow amount of hydrogel is adjusted by applying different pressures, thereby achieving precise control of the coating amount.

[0009] In some possible embodiments, the through hole is provided with a conical expansion hole away from the opening of the glue outlet. In this way, the hydrogel can flow more smoothly when passing through the through hole.

[0010] In some possible embodiments, the connecting block is semispherical. In this way, the friction when applying pressure can be reduced to some extent, thereby improving the outflow performance of the hydrogel.

[0011] In some possible embodiments, the hydrogel container is cylindrical, and the hydrogel coating device further comprises a propelling assembly, the propelling assembly comprising a blind hole sleeve, a propelling rod, and a propelling disc, the outer surface of the hydrogel container being provided with external threads; the inner surface of the blind hole sleeve is provided with internal threads, the internal threads and the external threads being matched with each other; the surface of the hydrogel container away from the glue outlet is provided with a through hole, the propelling rod is arranged in the through hole, one end of the propelling rod is fixedly connected with the bottom plate of the blind hole sleeve, and the other end of the propelling rod is fixedly connected with the propelling disc, the propelling disc being located in the hydrogel container. In this way, when the hydrogel in the hydrogel container is not enough, the propelling rod can be moved towards the glue outlet by rotating the blind hole sleeve, so that the propelling disc pushes the hydrogel to the glue outlet. In this way, on the one hand, the coating efficiency is improved; on the other hand, the waste of hydrogel is reduced.

[0012] In some possible embodiments, the outer wall surface of the hydrogel container is provided with a non-slip pad. In this way, the gripping stability of the user during operation is improved.

[0013] In some possible embodiments, the elastic member is a spring.

[0014] In some possible embodiments, the hydrogel container is transparent, and the outer wall surface of the hydrogel container is provided with a scale line. In this way, the user can easily observe the remaining amount of hydrogel. BRIEF DESCRIPTION OF DRAWINGS

[0025] A through hole 211 is arranged on the support plate 21, and one end of the elastic element 22 is fixedly connected with the support plate 21. Specifically, the elastic element 22 can be a spring. Of course, the present application is not limited to this. In other embodiments, the elastic element 22 can also be an elastic glue column. Exemplarily, the elastic element 22 and the support plate 21 can be fixedly connected in a manner of screw connection, clamping, bonding or the like. Specifically, the elastic element 22 can be directly fixedly connected with the support plate 21, or indirectly fixedly connected with the support plate 21 through a connecting plate or the like structure. It can be understood that the connection modes between subsequent various components can be designed in reference to the connection mode between the elastic element 22 and the support plate 21, and details are not described herein again. The other end of the elastic element 22 is fixedly connected with the connecting block 23, the center axis of the through hole 211 and the extension direction of the elastic element 22 are parallel to the center axis of the glue outlet 11, a ball running cavity 231 is arranged on the surface of the connecting block 23 away from the elastic element 22, the radius of the ball 24 is greater than the radius of the glue outlet 11, part of the ball 24 is movably arranged in the ball running cavity 231, and part of the ball 24 is located outside the glue outlet 11.

[0026] In this way, the user can lightly abut the ball 24 on the skin where the hydrogel needs to be smeared, so that the connecting block 23 pushes the spring to compress, thereby moving the ball 24 to the interior of the hydrogel smearing device, and then forming a gap between the ball 24 and the glue outlet 11 for the hydrogel to flow out. When the user removes the pressure, the elastic element 22 will rebound due to its elasticity, and the connecting block 23 and the ball 24 will also return to the initial state, thereby blocking the glue outlet 11.

In this way, when the hydrogel in the hydrogel container 1 is insufficient, the blind hole sleeve 31 can be screwed to drive the propelling rod 32 to move towards the glue outlet 11, so that the propelling disc 33 pushes the hydrogel to the glue outlet 11. In this way, on the one hand, the smearing efficiency can be improved, and on the other hand, the waste of hydrogel can be reduced.
