Description

Technical Field

[0001] This application relates to the technical field of foam combs, and in particular to a foam guiding structure and a detachable foam comb. Background Technology

[0002] Foam combs can transform shampoo into foam inside the comb body, which is then delivered directly to the scalp and hair through the hollow comb teeth. This increases the contact area between the shampoo and the scalp and hair. Combined with combing, it allows for application to affected areas of the head. Compared to traditional combs and washing methods, foam combs, with their innovative design, bring users an efficient and convenient treatment experience.

[0003] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: In the prior art, most foam combs are manually pressed to dispense foam, which is not only inconvenient to press to dispense foam during application, but also results in different amounts of foam dispensed due to varying pressing pressure, leading to uneven application of the medication, poor treatment effect, and increased treatment duration. Utility Model Content

[0004] To avoid uneven foam output from the foam comb, this application provides a foam guiding structure and a detachable foam comb.

[0005] This application provides a foam guiding structure and a detachable foam comb, which adopts the following technical solution: it includes a handle, the top of the handle is fixedly installed with the body, the left side of the body is fixedly installed with a screw plug, the inner wall of the body is fixedly installed with a connecting cylinder, and the outer wall of the connecting cylinder is snapped with a protective cover; The handle has several slots on its front.

[0012] In summary, this application includes the following beneficial technical effects: 1. This utility model is equipped with a forward button, a backward button, a piston, and other components. By pressing the backward button, the piston moves, drawing the liquid medicine into the water tank. At this time, the user can hold the handle and place the dispensing brush head on the scalp. Then, pressing the forward button causes the piston to move the piston cover at a constant speed. The piston cover pushes the liquid medicine in the water tank to spray out from the dispensing brush head and turn into foam to contact the scalp. This avoids uneven application of the liquid medicine due to uneven foaming during application, thus preventing the prolongation of the treatment course.

[0013] 2. This utility model, by incorporating components such as a tail cap, a slot, and a locking block, allows for easy replenishment of the medicine by rotating the tail cap counterclockwise until it reaches its maximum position. At this point, the locking block will be positioned at the maximum opening of the slot. Pulling the tail cap back will then release the foam bottle connected to the nozzle's silicone sleeve, allowing for replenishment of the medicine in the foam bottle. After replenishment, the foam bottle can be reinserted into the nozzle's silicone sleeve. The slot on the tail cap can then be aligned with the locking block, and the device can be rotated clockwise to reset it. This allows for quick disassembly and convenient replenishment of the medicine, enhancing the device's usability. Attached Figure Description

[0022] Please see Figure 2 As shown, a power button 2 is slidably connected to the inner wall of the slot in the middle. An assembly hole is provided on the front of the handle 1 near the back button 211. A light-transmitting column 212 is fixedly connected to the inner wall of the assembly hole. The light-transmitting column 212 allows the user to easily observe whether the device is in the state of suction or discharge of medicine. A main control PCBA 22 is fixedly connected to the inner wall of the handle 1. A battery 221 is fixedly connected to the back of the main control PCBA 22. A motor 222 is fixedly connected to the top of the battery 221.

[0023] Please see Figure 2 , Figure 3As shown, a motor gear 23 is fixedly connected to the output end of the motor 222 via a coupling. A transmission gear 231 is meshed with the top of the motor gear 23. A gear cylinder 24 is meshed with the top of the transmission gear 231 on the side away from the motor gear 23. A threaded hole is opened on the inner wall of the gear cylinder 24. A threaded moving post 241 is threadedly connected to the inner wall of the threaded hole. A limit groove is opened on the front of the threaded moving post 241. The inner wall of the limit groove contacts the limit post 242. The setting of the limit post 242 and the limit groove can limit the threaded moving post 241 and prevent it from moving beyond the specified range. The limit post 242 is fixedly connected to the inner wall of the connecting cylinder 12. A gear bracket 25 is fixedly connected to the front of the inner wall of the machine body 11.

[0024] Please see Figure 3 As shown, a nozzle silicone sleeve 251 is fixedly connected to the back of the gear bracket 25. The nozzle silicone sleeve 251 can be tightly connected to the foam bottle 3 for easy and quick disassembly. The front of the gear bracket 25 is rotatably connected to the back of the transmission gear 231 via a rotating shaft. A movable elbow 252 is rotatably connected to the front of the gear bracket 25.

An O-ring 26 contacts the inner wall of the fixing groove.

[0025] The implementation principle of the foam guiding structure and detachable foam comb in this application embodiment is as follows: By pressing the power button 2, the device is started. Then, by pressing the back button 211, the main control PCBA 22 starts the motor 222, causing the motor gear 23 to rotate counterclockwise. The counterclockwise rotating motor gear 23 drives the transmission gear 231 to rotate clockwise. The clockwise rotating transmission gear 231 drives the threaded moving column 241 to move backward through the gear cylinder 24 with a threaded hole. At this time, piston 27 will move backward under the movement of threaded moving column 241. At this time, the check valve on the dispensing brush head 291 will close, and a negative pressure will be formed inside the water tank 28, causing the water tank sleeve 253 to draw the medicine from the foam bottle 3 into the water tank 28. When the water tank 28 is full of medicine, the user can press the forward button 21 to make the motor gear 23 rotate clockwise. At this time, the threaded moving column 241 will drive piston 27 and piston cover 271 to move forward. At this time, the dispensing brush head... The check valve on piston 291 is open, while the check valve on piston 27 is closed. The piston cap 271, moving at a constant speed, sprays the medication through the dispensing brush head 291, turning it into foam. This ensures the foam is evenly distributed and contacts the user's scalp, preventing uneven application and prolonged treatment due to uneven foaming during application. To replenish the medication, rotate the tail cap 31 counter-clockwise until it reaches its maximum position. At this point, the locking block 32 will be at the maximum opening of the slot 311. Pull the tail cap 31 out, then remove the foam bottle 3 connected to the nozzle silicone sleeve 251 to replenish the medication. After replenishment, reinsert the foam bottle 3 into the nozzle silicone sleeve 251. Then, align the slot 311 on the tail cap 31 with the locking block 32 and rotate it clockwise to reset it. This allows for quick disassembly and easy medication replenishment, enhancing the device's convenience.
