Description

Technical Field

[0001] This utility model belongs to the field of coating devices, and specifically relates to a liquid coating head and coating device. Background Technology

[0002] Currently, liquids are often applied using fingers, but this method can soil the fingers, requiring handwashing afterward, which is inconvenient. Furthermore, applying liquids with uncleaned fingers can easily contaminate the liquid being applied.

[0003] To address the aforementioned problems, a prior patent disclosed a topical medication application device (application number 201721695436.2), belonging to the field of medical device technology. This invention aims to solve the problem that existing medication application methods easily cause secondary contamination of the medication, and that medication coming into contact with the affected area after infection is detrimental to patient treatment. This invention includes a medication delivery tube, an application device, and a cleaning cover. The medication delivery tube includes a tube body and a medication outlet located at the upper end of the tube body. The outer wall of the medication outlet has a threaded structure. The application device includes a threaded opening, an application rod, and an application head. The threaded opening is connected to the application rod and the application head. The application device is screwed onto the medication outlet of the medication delivery tube via the threaded opening. The cleaning cover is placed over the application device. With this medication applicator, patients can apply medication evenly to the affected area without using their hands, making it convenient and effective. However, during application, the spherical application head of this device does not easily spread the liquid evenly, affecting the application effect. Utility Model Content

[0004] The purpose of this invention is to provide a liquid application head that allows for convenient application of liquids and enables more even application of the liquid.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows.

[0006] A liquid applicator, characterized in that the applicator includes a cover and multiple bristles, one side of the cover is provided with a connection position for connecting to an external container, and the other side of the cover is provided with a liquid outlet hole extending through to the connection position; the multiple bristles are provided on the other side of the cover and correspond to the liquid outlet hole.

[0007] In this applicator head, by mounting the cap onto an outer container, the liquid contained in the outer container can flow out from the cap through the liquid outlet hole, and the liquid flowing out from the liquid outlet hole can be applied by the brush bristles; this method of applying the liquid with the brush bristles can make the liquid more evenly applied.

[0008] Furthermore, there is only one liquid outlet, located at the center of the cover. When a thinner liquid needs to be applied, having only one outlet at the center of the cover helps prevent excessive liquid overflow while ensuring that any overflowing liquid can be smoothly applied through the brush bristles.

[0009] Furthermore, there are multiple liquid outlet holes, with at least one outlet hole located at the center of the cap. When a thicker liquid needs to be applied, having multiple outlet holes, with at least one located at the center of the cap, can prevent insufficient liquid overflow during application.

[0010] Furthermore, the diameter of the bristles decreases from one end near the cover to the other end away from the cover, and the end of the bristles away from the cover has a bristle tip. This bristle structure design allows for more even application of liquid through the bristle tips.

[0011] Furthermore, the end of the brush bristles furthest from the cover is curved. This curved design ensures more even application of the liquid.

[0012] Furthermore, the curvature of at least two of the bristles at the ends furthest from the cover is different.

[0013] Furthermore, multiple bristles are detachably mounted on the cover. This detachable bristle configuration allows for the replacement of different bristles as needed.

[0014] Furthermore, the multiple bristles are divided into multiple groups, and each group of bristles is fixedly provided with a disassembly part. The other side of the cover is provided with multiple disassembly grooves that are adapted to the multiple disassembly parts respectively, and the multiple disassembly parts are detachably installed in the multiple disassembly grooves respectively.

[0015] Furthermore, the multiple bristles are divided into multiple groups, and each group of bristles is fixedly provided with a disassembly and assembly part. The cover body has multiple disassembly and assembly slots that are adapted to the multiple disassembly and assembly parts respectively, and the cover body also has multiple bristle holes that pass through the other side of the cover body. The multiple disassembly and assembly parts are detachably installed in the multiple disassembly and assembly slots respectively, and the multiple bristles extend from the bristle holes to the other side of the cover body respectively.

[0016] Furthermore, there is a disassembly / reassembly part that is arc-shaped or strip-shaped.

[0017] Furthermore, at least one side of the disassembly / assembly part is provided with an anti-detachment groove to improve the connection stability between the disassembly / assembly part and the disassembly / assembly groove; the disassembly / assembly groove is provided with an anti-detachment protrusion adapted to the anti-detachment groove. The cooperation between the anti-detachment protrusion and the anti-detachment groove increases the contact area between the disassembly / assembly part and the disassembly / assembly groove, which can make the connection between the disassembly / assembly part and the disassembly / assembly groove more stable.

[0018] Furthermore, the number of anti-detachment grooves on the disassembly / assembly part is one or more.

[0019] An applicator is characterized in that it includes a bottle body and an applicator head, the bottle body has a receiving cavity for containing liquid, one end of the bottle body has a connecting port extending into the receiving cavity, and the connecting part of the applicator head is installed at the connecting port.

[0020] Furthermore, the connection point is a connection groove located on one side of the applicator head, and the connection groove is detachably fitted onto the connection port. This detachable connection of the applicator head allows for easy replacement of the liquid inside the bottle.

[0021] Furthermore, a disassembly protrusion is fixed around the outside of the connection port, and a disassembly groove is provided around the side of the connection slot. The connection slot is sleeved at the connection port, and the disassembly protrusion is detachably snapped into the disassembly groove.

[0022] Furthermore, the bottle body has a compression section on at least one side, and the thickness of the compression section is less than the thickness of other parts of the bottle body. This thickness of the compression section allows for easy compression, thereby extruding liquid through deformation.

[0023] Furthermore, a compression protrusion is provided at the center of the compression section. The compression protrusion makes it more convenient to extrude liquid.

[0024] Furthermore, both sides of the bottle are provided with squeezing parts adapted to the size of a user's finger, and the ratio of the length or width of the squeezing part to the length or width of the bottle is less than two. This design makes the overall size of the application device smaller, making it convenient to carry and use.

[0025] The beneficial effect of this invention is that, in the applicator head, by installing the cover on the outer container, the liquid contained in the outer container can flow out from the cover through the liquid outlet hole, and the liquid flowing out from the liquid outlet hole can be applied by the brush bristles; this method of applying liquid with the brush bristles can make the liquid application more even.
