[0054] To address the problem that current hair care combs on the market are relatively large in overall structure, making them inconvenient for users to carry when traveling or on business, the inventors have provided a detachable hair care comb and liquid storage device, which are convenient for users to use and carry. This will now be described with reference to specific embodiments.

[0055] Example 1

[0056] Referring to Figures 1 to 10 , this embodiment provides a hair care comb 100 comprising a detachable main body 20 and a liquid storage device 10. The liquid storage device 10 is detachably connected to the main body 20 and can be used independently, functioning identically to the entire hair care comb 100, making it extremely convenient for travel.

[0057] Please refer to FIG. 3 and FIG. 5 . In this embodiment, the main body 20 includes a handle 21 and a second comb tooth seat 22 disposed at one end of the handle 21 .

[0058] The second comb holder 22 has a plurality of raised second comb teeth 224 formed on its end surface. A mounting cavity 221 is provided within the second comb holder 22 for mounting the liquid storage device 10. A power supply unit 211 is provided within the handle 21. Once the liquid storage device 10 is mounted in the mounting cavity 221, the power supply unit 211 provides power to the liquid storage device 10.

[0059] Specifically, referring to FIG. 3 , the main body 20 of this embodiment is formed by assembling a front shell 201 and a rear shell 202 . The detachable front shell 201 and rear shell 202 can facilitate the installation and replacement of internal parts of the main body 20 .

[0060] The interior space of the handle 21, formed by the front shell 201 and the rear shell 202, houses a power supply unit 211 and a main control board 212 connected to the power supply unit 211. In this embodiment, the power supply unit 211 is a built-in power supply. A charging port 213 is located at the bottom of the main control board 212, extending from the bottom surface of the handle 21. This port is a Type-C connector that can be connected to an external charging cable, allowing an external charging device to charge the power supply unit 211 through the charging port 213.

[0061] Please refer to FIG. 3 . In this embodiment, a button 214 is further provided on the handle 21 . The button 214 is electrically connected to the main control board 212 . The opening and closing of the hair care comb 100 or the function switching can be controlled by pressing the button 214 .

[0062] 3 and 5 , in this embodiment, the mounting cavity 221 in the second comb tooth seat 22 extends along its axial direction. A power supply contact 23 is provided on a side wall of the mounting cavity 221 , and the power supply contact 23 is electrically connected to the power supply unit 211 .

[0063] The liquid storage device 10 is provided with a power supply unit for supplying power. In this embodiment, the power supply unit includes power distribution contacts 14 disposed on the exterior surface of the liquid storage device 10. When the liquid storage device 10 is installed in the mounting cavity 221, the power supply contacts 23 contact the power distribution contacts 14, enabling the power supply unit 211 of the main body 20 to supply power to the liquid storage device 10.

[0064] Specifically, please refer to Figure 5. The power supply contact 23 on the installation cavity 221 of the main body 20 is electrically connected to the power supply unit 211 through the main control board 212. The current generated by the power supply unit 211 is transmitted to the liquid storage device 10 through the main control board 212 and then through the power supply contact 23, so that the button 214 connected to the main control board 212 can control the opening and closing of the liquid storage device 10.

[0065] Referring to FIG. 3 , in some examples of this embodiment, the power supply contact 23 on the main body 20 is a contact pin-type spring having a raised contact pin, the top of which slightly protrudes from the inner wall of the mounting cavity 221. The power distribution contact 14 on the outer surface of the liquid storage device 10 is a metal rectangular spring, which is arranged on the outer surface of the liquid storage device 10.

[0066] When the liquid storage device 10 is installed in the installation cavity 221 of the main body 20, the top contact pin of the power supply contact 23 on the main body 20 can fully contact the distribution contact 14 in the liquid storage device 10, so that the power supply unit 211 in the main body 20 supplies power to the liquid storage device 10.

[0067] 1 to 4 , the second comb tooth holder 22 of this embodiment is annular in shape, and the plurality of raised second comb teeth 224 on its end surface can increase the number of comb teeth of the hair care comb 100 as a whole, allowing the user to quickly comb the hair care liquid into the hair, thereby improving the use efficiency.

[0068] Please refer to Figure 4. In this embodiment, the second comb tooth seat 22 has a second LED lamp 24 and / or a second electrode 25 provided on the end surface of the comb teeth. The second LED lamp 24 and / or the second electrode 25 are respectively electrically connected to the power supply unit 211 in the handle 21.

[0069] Specifically, the second LED lamp 24 and the second electrode 25 are arranged in a circular pattern on the working end surface of the second comb teeth 224. The second LED lamp 24 is annular and has multiple spaced-apart light sources. It can emit one or more wavelengths of beauty light to care for the user's scalp. The second electrode 25 can generate pulsed current to massage acupuncture points on the user's head, allowing the hair care comb 100 to simultaneously massage the user's head while caring for the hair.

[0070] Furthermore, the second LED lamp 24 and the second electrode 25 are electrically connected to the power supply unit 211 via the main control board 212, allowing the user to control the second LED lamp 24 and the second electrode 25 on and off, or switch the modes of the second LED lamp 24 and the second electrode 25, by using the button 214 on the handle 21. For example, the second LED lamp 24 can emit light of different wavelengths, or the second electrode 25 can emit currents of different pulse intensities to provide a massage to the user.

[0071] It should be understood that the second LED lamp 24 and the second electrode 25 can be configured according to the actual use of the hair care comb 100.

[0072] In some embodiments, the second comb teeth 224 can be made of metal. When a power source is connected to the metal second comb teeth 224, the second comb teeth 224 form electrodes that can massage the scalp. Of course, the second comb teeth 224 can also be made of plastic, and a separate second electrode 25 is provided on the second comb tooth base 22 to massage the user.

[0073] Please refer to FIG. 3 . In this embodiment, a detachable connection method between the liquid storage device 10 and the main body 20 is also provided.

[0074] Specifically, a plurality of engaging blocks 222 are provided at intervals on the inner side wall of the mounting cavity 221 of the second comb tooth seat 22 , and a plurality of engaging grooves 117 corresponding one-to-one with the engaging blocks 222 are provided at intervals on the outer side surface of the shell 11 of the liquid storage device 10 .

[0075] When the liquid storage device 10 is installed in the mounting cavity 221 of the main body 20, the engaging block 222 on the second comb tooth seat 22 is accommodated in the engaging groove 117 in the liquid storage device 10, thereby securing the liquid storage device 10 in the mounting cavity 221 of the main body 20. To remove the liquid storage device 10, first rotate the liquid storage device 10 in the opposite direction to release the lock, then move the liquid storage device 10 backward along the axis of the liquid storage device 10 to remove the liquid storage device 10 from the main body 20.

[0076] The detachable connection between the liquid storage device 10 and the main body 20 is achieved by matching the clamping block 222 and the clamping groove 117, which can quickly install and remove the liquid storage device 10, making it convenient for users to use. In other embodiments, the liquid storage device 10 and the main body 20 can also be connected by threads.

[0077] Please refer to FIG. 3 and FIG. 9 . In this embodiment, the liquid storage device 10 includes a housing 11 , a first comb tooth seat 12 and a driving unit 13 .

[0078] The power supply unit of the liquid storage device 10 of this embodiment also includes a power supply interface 111 that cooperates with the power adapter 30. The power supply interface 111 is arranged on the outer surface of the housing 11, and the end of the power adapter 30 is electrically connected to the power supply interface 111. The power adapter 30 can be directly plugged into an outlet to power the liquid storage device 10.

[0079] In some other embodiments, the power supply unit may further include an external mobile power bank, which is connected to the power supply interface 111 via a power cord to supply power to the liquid storage device 10 .

[0080] The housing 11 includes a liquid storage chamber 112 and a compression chamber 113 connected to the liquid storage chamber 112. A first comb tooth holder 12 is disposed on the housing 11 and includes a plurality of comb teeth protruding away from the housing 11. The ends of the comb teeth away from the housing 11 form a liquid outlet that communicates with the liquid storage chamber 112.

[0081] The driving unit 13 includes a moving member 131 and a driving member 132. The moving member 131 is disposed in the compression chamber 113 and is movable along the axis of the compression chamber 113 to change the pressure in the liquid storage chamber 112 connected to the compression chamber 113.

[0082] The driving member 132 is disposed within the housing 11 and electrically connected to the power supply interface 111. The output end of the driving member 132 is connected to the moving member 131. When the driving member 132 is connected to a power source via the power supply interface 111, the driving member 132 can drive the moving member 131 to reciprocate within the compression chamber 113, thereby squeezing the liquid in the liquid storage chamber 112 out of the liquid outlet.

[0083] The liquid storage device 10 in this embodiment can be used independently. Simply connect the power supply port 111 on the liquid storage device 10 to the mains electricity supply via the power adapter 30. The internal drive motor then squeezes the hair care or hair growth solution, such as liquid, from the liquid storage chamber 112 out the ends of the first comb teeth 121 to condition the hair. Its functionality is similar to that of the integrated hair care comb 100, but its compact size makes it convenient for travel, significantly improving the user experience. In this embodiment, the liquid storage device 10 does not contain a battery, facilitating travel security checks.

[0084] Referring to Figure 9 , in some examples of this embodiment, a liquid storage chamber 112, a compression chamber 113, and a storage chamber 119 are formed within the housing 11. The liquid storage chamber 112 is used to store liquids such as hair-building and hair-growing liquids. The compression chamber 113 is used to accommodate a moving member 131, which moves within the compression chamber 113 to compress air. The storage chamber 119 is used to accommodate devices such as the drive unit 13. Of course, in other embodiments, conventional components may be directly disposed within the liquid storage chamber 112 or the compression chamber 113.

[0085] Please refer to FIG. 9 in conjunction with FIG. 3 , the driving unit 13 includes a moving member 131 , a driving member 132 , a spur gear 133 and a crown gear 134 .

[0086] The driving member 132 can be a driving motor, the output end of which is connected to a vertical spur gear 133. The spur gear 133 is engaged with a parallel crown tooth 134. A positioning rod is provided on the upper end surface of the crown tooth 134. The driving motor can drive the positioning rod on the crown tooth 134 to rotate circumferentially.

[0087] Moving member 131 is a piston-connecting rod mechanism. The piston is positioned within compression chamber 113 and is completely in contact with the inner wall of compression chamber 113. The connecting rod on the piston is fixedly connected to the positioning rod on crown gear 134. When the driving motor drives the positioning rod on crown gear 134 to rotate circumferentially, it drives the piston to reciprocate within compression chamber 113 to compress air.

[0088] It is conceivable that the driving member 132 may also be a hydraulic device, which drives the moving member 131 in the compression chamber 113 to reciprocate through the telescopic hydraulic device.

[0089] Please refer to Figures 3 and 9. In this embodiment, an air inlet hole 1121 is further provided on the side wall of the liquid storage chamber 112. A one-way air inlet valve (not shown in the figure) is provided in the air inlet hole 1121 to allow air to enter the liquid storage chamber 112 from the outside to balance the air pressure in the liquid storage chamber 112.

[0090] Specifically, when the moving member 131 moves toward the liquid storage chamber 112, the pressure in the liquid storage chamber 112 increases, and the liquid in the liquid storage chamber 112 is pressurized, causing it to flow out of the liquid outlet of the first comb teeth 121. When the moving member 131 moves away from the liquid storage chamber 112, the pressure in the liquid storage chamber 112 decreases, and air in the receiving chamber 119 enters the liquid storage chamber 112 through the one-way air inlet valve in the air inlet, thereby balancing the air pressure in the liquid storage chamber 112. This allows the moving member 131 to continue to pressurize the liquid storage chamber 112 the next time it moves toward the liquid storage chamber 112, squeezing out the liquid in the liquid storage chamber 112.

[0091] It should be understood that the air inlet 1121 and the one-way air inlet valve in the air inlet 1121 may also be located on the outer side of the shell 11 , as long as one-way air intake to the liquid storage chamber 112 can be achieved.

[0092] Referring to Figures 9 and 10 , the power supply interface 111 in this embodiment is a Type-C interface. This standard interface facilitates compatibility with the power adapter 30. Furthermore, a sub-control board 116 is provided at the power supply interface 111 in this embodiment. The sub-control board 116 is electrically connected to the power supply interface 111 and the driver 132 to control the movement of the driver 132.

[0093] It is contemplated that in other embodiments, the power supply interface 111 and the power distribution contacts 14 may be the same power supply unit. That is, when the liquid storage device 10 is installed with the main body 20, it is electrically connected to the main body 20 via the same power supply unit. When the liquid storage device 10 is used alone, the power supply unit may also be connected to an external power adapter 30 or a power cord, thereby simplifying the structure of the housing 11.

[0094] Please refer to FIG. 8 and FIG. 9 . In some examples of this embodiment, the housing 11 and the first comb tooth seat 12 are an integrated structure, which has high structural strength and the liquid storage device 10 is not easily damaged.

[0095] Referring to FIG. 9 , in some examples of this embodiment, the first comb tooth holder 12 has a first LED lamp 15 and / or a first electrode (not shown) on the end surface of the comb teeth. The first comb tooth holder 12 and the outer surface of the housing 11 are provided with interconnected power distribution contacts 14 for electrically connecting the first LED lamp 15 and / or the first electrode to the power supply interface 111 on the housing 11.

[0096] In some embodiments, the first comb teeth 121 may be made of metal. When a power source is connected to the metal first comb teeth 121, the first comb teeth 121 form electrodes that can massage the user's scalp. Of course, the first comb teeth 121 can also be made of plastic, and a separate first electrode is provided on the first comb tooth base 12 to massage the user.

[0097] It should be understood that the first LED light 15 and first electrode on the first comb tooth holder 12 and the second LED light 24 and second electrode 25 on the second comb tooth holder 22 have the same structure and function, and both can provide a health massage for the user's head. Furthermore, the ends of the second electrode 25, the first electrode, the second comb teeth 224, and the first comb teeth 121 are aligned. That is, the first electrode, the second comb teeth 224, and the first comb teeth 121 are of the same length, and their ends are in the same plane, allowing the second electrode 25 and the first electrode to contact the user's scalp for massage.

[0098] Referring to Figures 3 and 9 , in this embodiment, the housing 11 and first comb tooth holder 12 are integrally formed, and the power distribution contacts 14, disposed on the outer surfaces of the first comb tooth holder 12 and the housing 11, are also integrally formed. One end of the integral power distribution contact 14 is disposed on the end surface of the first comb tooth holder 12 and electrically connected to the first LED lamp 15 and / or the first electrode; the other end is disposed in the receiving cavity 119 and electrically connected to the auxiliary control board 116, enabling the power supply interface 111 to supply power to the first LED lamp 15 and / or the first electrode via the auxiliary control board 116.

[0099] The power distribution contact 14 is disposed on the outer surface of the liquid storage device 10 so as to completely contact the power supply contact 23 of the main body 20 , so that the power supply unit 211 of the main body 20 can supply power to the first LED lamp 15 , the first electrode, and the driving member 132 .

[0100] Referring to Figures 3, 8, and 9, in this embodiment, the outer surface of the housing 11 is provided with a liquid filling port 114 that communicates with the liquid storage chamber 112. A sealing plug 115 is provided on the liquid filling port 114 to seal it. When the user removes the sealing plug 115, they can add hair-nourishing liquid to the liquid storage chamber 112, making the liquid storage device 10 reusable and improving its economic value.

[0101] Referring to Figure 8 , in some examples of this embodiment, the housing 11 has a grip portion 110 on the outer side of the first end away from the first comb tooth holder 12. The grip portion 110 includes a plurality of anti-slip grooves extending axially along the housing 11, and the plurality of anti-slip grooves are evenly distributed along the circumference of the housing 11. The grip portion 110 is located at the end away from the first comb tooth holder 12, making it easy for the user to grip and facilitate standalone use of the liquid storage device 10.

[0102] Referring to Figure 9 , in some examples of the present invention, a ball 122 is disposed within the first comb teeth 121. The ball 122 is rotatably positioned at the liquid outlet of the first comb teeth 121, for rolling contact with the skin. When liquid within the liquid storage chamber 112 enters the ball 122 at the liquid outlet at the end of the first comb teeth 121, it is drawn out onto the skin through contact with the ball 122. This liquid discharge through the ball 122 ensures more uniform liquid discharge and more even mixing of the liquid with the hair.

[0103] In summary, the liquid storage device 10 of this embodiment is detachably connected to the hair care comb 100 and can be used independently. Its functionality is similar to that of the entire hair care comb 100, but its compact size makes it convenient for use while traveling, significantly improving the user experience. During assembly and use, the liquid storage device 10 is mounted on the main body 20 of the hair care comb 100. The handle 21 on the main body 20 facilitates gripping by the user. The power supply unit 211 within the handle 21 supplies power to the liquid storage device 10, freeing it from the constraints of the power adapter 30. The second comb tooth holder 22 on the main body 20 also provides a larger working area, improving hair care efficiency.

[0104] Example 2

[0105] Referring to Figures 11 to 14 , the main difference between the hair care comb 100 of this embodiment and the first embodiment is that the liquid storage device 10 of this embodiment is a split structure, with the housing 11 and the first comb tooth holder 12 detachably connected. Based on this split structure, an alternative connection structure between the liquid storage device 10 and the main body 20 of the hair care comb 100, as well as a power supply and distribution structure, is provided. These structures, which are identical to those of the first embodiment, will not be repeated in this embodiment.

[0106] 13 and 14 , in this embodiment, a first connecting portion 118 is provided on the end surface of the housing 11 of the liquid storage device 10 facing the first comb tooth seat 12 , and a liquid outlet communicating with the liquid storage chamber 112 is defined in the first connecting portion 118 .

[0107] A second connecting portion 123 is provided on the end of the first comb tooth holder 12 facing the housing 11. A liquid inlet is defined within the second connecting portion 123 and communicates with the liquid outlet of the first comb teeth 121. The second connecting portion 123 is detachably connected to the first connecting portion 118, connecting the liquid outlet on the housing 11 with the liquid inlet on the first comb tooth holder 12.

[0108] Specifically, the first connecting portion 118 is a protruding column with external threads on its outer surface, while the second connecting portion 123 is a recessed groove with internal threads on its inner wall. The first connecting portion 118 is received within the second connecting portion 123 and is fixedly connected via threads, thereby securing the housing 11 and the first comb tooth holder 12. Furthermore, the liquid outlet on the first connecting portion 118 mates with the liquid inlet on the second connecting portion 123, allowing liquid in the liquid storage chamber 112 to flow out smoothly.

[0109] It is conceivable that the first connection portion 118 and the second connection portion 123 can also be connected by snap-fitting or mortise and tenon jointing, as long as the shell 11 and the first comb tooth seat 12 can be detachably connected and the liquid inlet is connected to the liquid outlet.

[0110] Referring to Figures 12 and 13 , in some examples of this embodiment, a thin film is provided on the first connection portion 118 of the housing 11 to seal the liquid outlet. A pin 124 is provided within the second connection portion 123 of the first comb holder 12. The pin 124 protrudes toward the housing 11 and is used to puncture the thin film.

[0111] When the housing 11 leaves the factory, the liquid chamber 112 is already filled with hair-nourishing liquid. The liquid outlet at the first connecting portion 118 is sealed with a thin membrane to protect the liquid in the chamber 112 from oxidation by air. To use the housing 11, simply dock the first comb holder 12 with the housing 11 and puncture the membrane. After use, the housing 11 can be replaced with a new one containing hair-nourishing liquid, or refilled through the liquid filling port 114 on the housing 11 for reuse.

[0112] 11 and 12 , based on the split structure of the housing 11 and the first comb teeth 121 , this embodiment further provides another connection method of the liquid storage device 10 and the main body 20 of the hair care comb 100 .

[0113] A partition 223 is provided within the mounting cavity 221 of the second comb tooth holder 22, and a through hole is formed in the partition 223. The first connecting portion 118 on the housing 11 passes through the through hole and is threadedly connected to the second connecting portion 123 of the first comb tooth holder 12 on the other side of the partition 223. The housing 11 and the first comb tooth holder 12 are respectively disposed on either side of the partition 223, and the partition 223 is clamped together to secure the liquid storage device 10 to the second comb tooth holder 22 of the main body 20.

[0114] The liquid storage device 10 is fixed by clamping the partition 223 through the shell 11 and the first comb tooth seat 12, which not only realizes the detachable connection between the liquid storage devices 10, but also improves the connection stability of the liquid storage device 10, so that the liquid storage device 10 and the main body 20 will not be easily separated.

[0115] 11 to 13 , based on the split structure of the housing 11 and the first comb teeth 121 , the distribution contact 14 of this embodiment also consists of two parts, including a metal spring 141 and a contact pin spring 142 that cooperate with each other.

[0116] One end of the stylus shrapnel 142 is disposed on the outer surface of the first comb tooth seat 12 and is electrically connected to the first LED lamp 15 and / or the first electrode on the first comb tooth seat 12, while the stylus portion of the stylus shrapnel 142 is protruding from the end surface of the first comb tooth seat 12 facing the housing 11 and is configured to abut against the metal shrapnel 141 on the housing 11. When the first comb tooth seat 12 is connected to the housing 11, the metal shrapnel 141 and the stylus shrapnel 142 abut against each other, thereby electrically connecting the first LED lamp 15 and / or the first electrode on the first comb tooth seat 12 to the power supply interface 111.

[0117] In addition, referring to Figures 11 and 12, in this embodiment, two groups of power supply contacts 23 are provided on the main body 20. Both groups of power supply contacts 23 are contact pin-type springs, which can be electrically connected to the contact pin spring 142 on the first comb tooth seat 12 and the metal spring 141 on the shell 11 respectively, so as to enable the main control board 212 in the handle 21 to control the first LED lamp 15 on the first comb tooth seat 12 and the driving member 132 in the shell 11 respectively.

[0118] It should be understood that the power supply contacts 23 and the distribution contacts 14 in this embodiment may also be of other structural shapes, as long as they can achieve conduction when the liquid storage device 10 is connected to the main body 20 and the first comb tooth seat 12 is connected to the shell 11.

[0119] In summary, by setting the liquid storage device 10 as a split structure, the first comb tooth seat 12 and the shell 11 are detachably connected, which facilitates the replacement of the first comb tooth seat 12 and the shell 11 of the liquid storage device 10. The user can replace the shell 11 with different hair care liquids or the first comb tooth seat 12 with different functions at any time during use, further improving the convenience of use and enhancing the user experience.

[0120] Example 3

[0121] Please refer to Figures 15 to 20. The main difference between this embodiment and the hair care comb 100 in Example 1 is that the power supply part in the liquid storage device 10 is a battery 16, which supplies power to the driving unit 13 and other components through the battery 16 set in the liquid storage device 10, making it more convenient to use the liquid storage device 10 alone.

[0122] Please refer to FIG. 16 and FIG. 17 . In this embodiment, the battery 16 is electrically connected to the driver 132 and the first LED lamp 15 through the auxiliary control board 116 , and supplies power to the driver 132 and the first LED lamp 15 .

[0123] In this embodiment, a control key 17 is further provided on the housing 11 . The control key 17 is electrically connected to the auxiliary control board 116 to control the switching of the driving member 132 and the first LED lamp 15 .

[0124] In some examples of this embodiment, the power supply interface 111 on the liquid storage device 10 can directly power the driving member 132 and charge the battery 16 in the housing 11 .

[0125] It is conceivable that the power supply interface 111 may not be provided on the liquid storage device 10. It is only necessary to provide a detachable battery back cover at the position of the shell 11 corresponding to the battery 16, and the depleted battery 16 can be replaced through the detachable battery back cover.

[0126] In this embodiment, by disposing a battery 16 in the liquid storage device 10, the liquid storage device 10 can be used independently without being restricted by the power adapter 30 or the power supply, thereby further improving its convenience.

[0127] Example 4

[0128] 21 to 24 , the main difference between the hair care comb 100 of this embodiment and the second embodiment is that the driving unit 13 is not provided in the liquid storage device 10 of this embodiment.

[0129] As shown in Figures 23 and 24, the liquid storage device 10 also includes a shell 11 and a first comb tooth seat 12 that are detachable from each other. The first comb tooth seat 12 is located in the installation cavity 221 of the main body 20, and the end surface of the first comb tooth seat 12 is structured to form a plurality of protruding first comb teeth 121, and the ends of the first comb teeth 121 form a liquid outlet. A liquid storage chamber 112 is provided in the shell 11 for storing liquid. The shell 11 is provided with a liquid storage chamber 112, and the shell 11 is detachably connected to the first comb tooth seat 12, and the liquid storage chamber 112 is connected to the liquid outlet, so that the liquid in the liquid storage chamber 112 can be discharged from the liquid outlet.

[0130] The connection method between the housing 11 and the first comb tooth seat 12 is the same as that in the second embodiment, and the installation method of the liquid storage device on the main body 20 is also the same as that in the second embodiment, which will not be repeated here.

[0131] In this embodiment, when the hair care comb 100 is in use, the first comb teeth 121 are vertically downward most of the time. Therefore, the liquid in the housing 11 can be discharged from the liquid outlet of the first comb teeth 121 under the influence of gravity.

[0132] In this embodiment, since the drive unit 13 is not provided within the liquid storage device 10, no moving parts, drive parts, or power supply are required within the housing 11. This results in a simple structure and low manufacturing costs. When the hair care liquid or hair growth liquid in the housing 11 is used up, the user only needs to purchase a new housing 11 pre-packaged with the hair care liquid or hair growth liquid and replace the old housing 11 with the new housing 11 on the first comb tooth holder 12. This eliminates the need for the user to reuse the same housing 11, eliminates the need to clean the housing 11, and eliminates the need for the user to refill the housing 11, further facilitating user use and making it more convenient for the user. The absence of the drive unit 13 within the housing 11 reduces the overall volume of the liquid storage device 10, making it more portable. This also effectively reduces the production cost of the housing 11, thereby reducing the user's cost of replacing the housing 11.

[0133] While the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are intended to be illustrative and exemplary rather than restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope of the appended claims. All changes and modifications that fall within the scope of the claims or their equivalents are intended to be covered by the appended claims.
