[0028] This embodiment relates to a liquid outlet comb, such as... Figure 1 - Figure 7 As shown, the device includes a housing 1, a comb tooth module 2, a liquid reservoir 3, and a plug structure 4. The housing 1 has a first housing 10 and a second housing 11 connected to each other. The comb tooth module 2 is disposed on the first housing 10, and the liquid reservoir 3 is disposed inside the housing 1. The first housing 10 and the second housing 11 cooperate to form a mounting cavity for protecting the liquid reservoir 3. The liquid reservoir 3 is used to supply liquid to the comb tooth module 2, enabling the liquid comb to provide liquid care during hair combing. The liquid reservoir 3 has an inlet 30 that penetrates the second housing 11 to communicate with the outside, allowing the user to add or replenish medicine or essential oil to the liquid reservoir 3 through the inlet 30. The plug structure 4 includes an elastic sealing element 41 and a cover 42, which is detachably mounted on the first housing 1. The first housing 10 and the cover 42 form a receiving space, and the second housing 11 is hidden in the receiving space, which improves the appearance of the liquid comb. The elastic sealing member 41 is connected to the inner wall of the cover 42. The elastic sealing member 41 is movably installed on the liquid inlet 30 to block or open the liquid inlet 30. The sealing member is made of elastic material to ensure a tight seal between the elastic sealing member 41 and the liquid inlet 30, reducing liquid leakage. At the same time, the elastic sealing member 41 and the second housing 11 are both located inside the cover 42. The elastic sealing member 41 and the liquid inlet 30 are not exposed to the external environment. The cover 42 can protect the elastic sealing member 41 and the liquid inlet 30, reducing the entry of dust, hair and other small impurities into the gap between the elastic sealing member 41 and the liquid inlet 30. As the cover 42 is removed from the second housing 11, the elastic sealing element 41 opens the liquid inlet 30, or as the cover 42 is placed on the second housing 11, the sealing element simultaneously blocks the liquid inlet 30, making the operation convenient.

[0029] Optional, such as Figure 3 - Figure 7As shown, the elastic sealing element 41 can be made of elastic plastic, such as elastic silicone or elastic rubber. Specifically, to ensure a sealed connection between the elastic sealing element 41 and the inlet 30, a sealing ring 412 can also be provided on the outer surface of the elastic sealing element 41. Multiple sealing rings 412 are provided, spaced apart along the axial direction of the elastic sealing element 41 on its outer surface. The sealing rings 412 can be integrally formed or fitted onto the outer surface of the elastic sealing element 41.

[0030] In some embodiments, such as Figure 1 - Figure 6 As shown, the first housing 10 includes a bottom wall 101 and a first circumferential side wall 102 connected to each other. The comb module 2 is disposed on the bottom wall 101, and the first circumferential side wall 102 extends from the edge of the bottom wall 101 in a direction close to the first housing 10. The cover 42 includes a top wall 421 and a second circumferential side wall 422 connected to each other. The second circumferential side wall 422 extends from the edge of the top wall 421 in a direction close to the first housing 10. Specifically, the liquid inlet 30 penetrates through the top of the second housing 11, which allows more medicine or essential oil to be contained when the comb is placed in the axial direction. At the same time, during the combing process, since the liquid inlet 30 faces upward, the risk of medicine leakage from the liquid inlet 30 during the combing process is further reduced. The first circumferential sidewall 102 is offset from the second housing 11, forming a placement space between the outer wall of the second housing 11 and the first circumferential sidewall 102. The second circumferential sidewall 422 is located in the placement space, and the first circumferential sidewall 102 and the second circumferential sidewall 422 are arranged opposite each other along the axial direction of the first housing 10. In this embodiment, the side of the second circumferential sidewall 422 away from the top wall 421 abuts against the second circumferential sidewall 422, thereby completely concealing the second housing 11 and the liquid inlet 30. This makes the appearance of the liquid outlet comb more aesthetically pleasing and reduces the risk of dust entering the interior of the liquid outlet comb from the gap between the elastic sealing member 41 and the liquid storage tank 3, thus contaminating the liquid.

[0031] Optionally, to achieve the assembly of housing 1, such as Figure 4 - Figure 6 As shown, the second housing 11 is partially inserted into the first housing 10, with the remaining portion exposed on the outer surface of the first housing 10. The outer surface of the first housing 10 is provided with a plurality of first latching portions spaced circumferentially. The inner side of the first circumferential sidewall 102 is provided with a plurality of second latching portions spaced circumferentially, each engaging with one of the first latching portions. One of the first and second latching portions is a wedge-shaped protrusion, and the other is a latching hole or latching groove. In other embodiments, the first housing 10 and the second housing 11 are fixed together by screws.

[0032] In some embodiments, to achieve synchronous movement between the cover and the resilient sealing element, the cover and the resilient sealing element are fixed by bonding, thermoforming, or integral molding. In other embodiments, the cover can be connected to the resilient sealing element via a detachable connection structure such as screws or snap-fit ​​structures.

[0033] In some embodiments, such as Figure 1 , Figure 3 As shown, in order to make the outer surface of the liquid dispensing comb more coherent and aesthetically pleasing, the outer surface of the first circumferential sidewall 102 is flush with the outer surface of the second circumferential sidewall 422, so that the outer surface of the liquid dispensing comb is coplanar, reducing the step-like feeling when holding the liquid dispensing comb, thereby improving the user's comfort.

[0034] In some embodiments, such as Figure 1 , Figure 3 As shown, in order to make the outer surface of the liquid dispensing comb more coherent and aesthetically pleasing, the curvature of the first circumferential sidewall 102 and the second circumferential sidewall 422 are the same along the axial direction of the first housing 10, which improves the smooth transition of the outer surface of the liquid dispensing comb and thus enhances the user's comfort.

[0035] In some embodiments, such as Figure 1 , Figure 3 As shown, in order to make the outer surface of the liquid dispensing comb more coherent and aesthetically pleasing, the curvature of the first circumferential sidewall 102 and the second circumferential sidewall 422 are the same along the circumferential direction of the first housing 10, thereby improving the user's comfort.

[0036] In some embodiments, the cover 42 further includes at least two ears 423 disposed on the outer surface of the cover 42. A gap is formed between adjacent ears 423 for inserting fingers, providing a fulcrum for gripping. Users can insert fingers, gripping one ear 423 between two fingers while simultaneously pulling the cover 42 upwards to disassemble it. This operation is effortless and reduces slippage when opening the inlet 30 by hand. In other embodiments, the top of the cover 42 also has a ring-shaped handle providing gripping force. Users can insert fingers into the round hole of the handle, hook upwards, and pull to disassemble the cover 42, also requiring less effort.

[0037] In some embodiments, such as Figure 1 , Figure 2 , Figure 4 , Figure 9 As shown, to increase the fun of the cover 42, two ears 423 are spaced apart. The ears 423 are triangular, and the gap between the two ears 423 is V-shaped or U-shaped. The two ears 423 spaced apart make the shape of the liquid comb look like a cat's head, thereby increasing the fun of the liquid comb and making the liquid comb usable as a decorative item.

[0038] In some embodiments, such as Figure 3 - Figure 6 As shown, to achieve linkage between the cover 42 and the elastic sealing member 41, and to facilitate the fixed connection of the cover 42 and the elastic sealing member 41, which are made of different materials, the elastic sealing member 41 has a fixing groove 410 extending along the axial direction of the liquid inlet 30. The inner side wall of the fixing groove 410 is provided with a first engaging part 411. A fixing part 4211 protrudes from the top wall 421 towards the liquid inlet 30. The fixing part 4211 is inserted into the fixing groove 410. The outer side wall of the fixing part 4211 is provided with a second engaging part 4212 that engages with the first engaging part 411. One of the first engaging part 411 and the second engaging part 4212 is a protrusion, and the other is a groove that engages with the protrusion. Optionally, the second snap-fit ​​portion 4212 is integrally disposed at the end of the fixing portion 4211. Along the axial direction of the fixing portion 4211, the outer diameter of the second snap-fit ​​portion 4212 is larger than the outer diameter of the fixing portion 4211. The second snap-fit ​​portion 4212 is annular or has multiple protrusions spaced apart. The first snap-fit ​​portion 411 is a groove adapted to the second snap-fit ​​portion 4212. The first snap-fit ​​portion 411 is annular and its outer diameter is larger than the outer diameter of the fixing groove 410.

[0039] In some embodiments, such as Figure 6 , Figure 9 As shown, to achieve the function of dispensing liquid through the comb, the comb module 2 includes liquid-guiding comb teeth 20, with multiple liquid-guiding comb teeth 20 spaced apart. One end of each liquid-guiding comb tooth 20 is mounted on the liquid storage chamber 3, and the other end is exposed in the first housing 10. The liquid-guiding comb teeth 20 have an outlet channel connecting the outside to the liquid storage chamber 3. In other embodiments, the bottom wall 101 of the second housing 11 has an outlet channel connecting the liquid storage chamber 3 to the outside. An atomizer (not shown in the figure) is installed in the liquid storage channel to atomize the liquid in the liquid storage chamber 3 and spray it out through the outlet channel. This atomizer can be an ultrasonic atomizer.

[0040] In some embodiments, such as Figure 6As shown, the liquid-guiding comb teeth 20 are made of rigid materials, such as stainless steel or silver alloy. The comb teeth 20 are fixed to the liquid storage tank 3 with adhesive or hot melt adhesive. A ball bearing 201 and a spring 202 with one end abutting against the ball bearing 201 are installed in the liquid outlet channel. The ball bearing 201 is movably mounted in the liquid outlet channel at the end away from the liquid storage tank 3. The ball bearing 201 can block the liquid outlet channel under the restoring force of the spring 202. When the comb is not in contact with the user's scalp, the ball bearing 201 automatically closes the liquid outlet channel under the pre-tension force of the spring 202, reducing liquid leakage and waste. When combing hair, the user's skin presses the ball bearing 201 to compress the spring 202, opening the liquid outlet channel and allowing the liquid to be applied to the roots of the hair, thus preventing liquid waste. In other embodiments, the comb teeth 20 can also be fixed to the liquid storage tank 3 by screws and clamping devices.

[0041] In some embodiments, such as Figure 9 As shown, the liquid-guiding comb teeth 20 are made of flexible material and can be fixed to the liquid storage tank 3 by hot injection molding or hot melt adhesive. A valve component 203 is provided at the end of the liquid-guiding comb teeth 20 away from the liquid storage tank 3, which can open or close the liquid outlet channel. The liquid-guiding comb teeth can be made of soft plastics such as rubber or silicone. Soft plastic materials have good flexibility, and elastic silicone is preferred. This avoids scratching the scalp or pulling hair during combing. During the combing process, when the comb teeth contact the scalp and are under pressure, the liquid outlet automatically opens. When there is no pressure, the liquid-guiding comb teeth 20 and the valve component 203 reset under their own elasticity to close the flow channel. The valve component 203 can be made of soft silicone or soft rubber.

[0042] In some embodiments, such as Figure 3 , Figure 6 As shown, the comb module 2 also includes spaced-apart soft comb teeth 21. Multiple soft comb teeth 21 are located on the side of the first housing 10 away from the second housing 11. The end of the soft comb teeth 21 away from the second housing 11 is flush with the end of the liquid-guiding comb teeth 20 away from the second housing 11. The soft comb teeth 21 are made of soft silicone or soft rubber, preferably soft silicone. The arrangement of the soft comb teeth 21 can buffer the force during the hair combing process, reducing the irritation caused by the rigid liquid-guiding comb teeth 20 directly contacting the scalp. The flush arrangement of the soft comb teeth 21 and the liquid-guiding comb teeth 20 ensures their synergistic effect; the soft comb teeth 21 can disperse the hair while guiding the liquid to adhere evenly to the hair surface or hair roots.

[0043] In some embodiments, such as Figure 3 - Figure 5As shown, the comb module 2 also includes a fixing disk covering the bottom wall 101 of the first housing 10. The fixing disk has a plurality of soft comb teeth 21 distributed circumferentially. Liquid-guiding comb teeth 20 penetrate the fixing disk, with one end flush with the end of each soft comb tooth 21, and the liquid-guiding comb teeth 20 are press-fitted with the fixing disk. In this embodiment, the fixing disk and the soft comb teeth 21 are integrally formed, both made of rubber or silicone.

[0044] In some embodiments, such as Figure 4 - Figure 6 As shown, the first housing 10 has a light-transmitting area 103 on the side near the comb module 2. The liquid-discharging comb also includes a phototherapy component 5 disposed in the first housing 10. The phototherapy component 5 is disposed adjacent to the light-transmitting area 103 and can emit light toward the light-transmitting area 103.

[0045] In some embodiments, such as Figure 4 - Figure 6 As shown, the comb module 2 includes multiple soft comb teeth 21 spaced apart on the light-transmitting area 103. The fixing plate forms the light-transmitting area 103. The soft comb teeth 21 are made of light-transmitting material. Multiple through holes 104 are provided on the bottom wall 101 of the first housing 10, which are arranged one-to-one with the soft comb teeth 21. The phototherapy component 5 includes a first circuit board 51 and multiple light emitters 52. The first circuit board 51 is disposed inside the first housing 10 and adjacent to the bottom wall 101. The multiple light emitters 52 are spaced apart on the first circuit board 51, and each of the multiple light emitters 52 is inserted into the multiple through holes 104. The light emitted by the light emitters 52 can be irradiated outward through the soft comb teeth 21. Optionally, the fixing plate is fixed to the outer shell 1 by hot injection molding and a snap-fit ​​structure. Optionally, the light emitters 52 can emit red light with a wavelength of 630nm-670nm or near-infrared light with a wavelength of 800nm-850nm. The light source 52 can be selected from LED beads, semiconductor laser diodes, helium-neon lasers or halogen beads.

[0046] It should be noted that, in order to achieve the therapeutic function of the fluid-discharging comb, such as Figure 4 - Figure 6 As shown, the housing 1 also contains a main control board 53 and a battery 54. The main control board 53 is connected to the first circuit board 51 and the battery 54. The first housing 10 also contains a control switch 55 and a charging structure 56 that are electrically connected to the main control board 53. The control switch 55 can be a touch switch, a push switch or a toggle switch. The charging structure 56 can be a charging electrode, a wireless charging coil, a USB-A interface, a USB-C interface, a Lightning interface or a Micro-USB interface.

[0047] In some embodiments, the comb module 2 further includes at least two metal comb teeth (not shown in the figure) and other stimulation elements disposed on the bottom wall 101. The at least two metal comb teeth form two sets of microcurrent electrodes electrically connected to the main control board 53, so as to realize the triple physiotherapy functions of electrotherapy, fluid discharge and phototherapy of the liquid discharge comb, thereby increasing the functionality of the liquid discharge comb.

[0048] In some embodiments, to further enhance the therapeutic function of the drainage comb, the stimulation element also includes a vibrator (not shown) embedded in the first housing 10 and electrically connected to the main control board 53. An ultrasonic vibrator may be used, giving the drainage comb a vibration massage function. In some embodiments, such as Figure 8 As shown, in order to support and protect the comb tooth module 2, the liquid dispensing comb also includes a dust cover 6. The dust cover 6 has a placement cavity for placing the comb tooth module 2. The comb tooth module 2 of the liquid dispensing comb is inserted into the placement cavity and the first housing 10 is limited to being exposed outside the first housing 10.
