Description

Technical Field

[0001] This utility model specifically relates to a detachable connection structure for a steam comb water tank. Background Technology

[0002] With the continuous development of personal care appliances, steam combs, as a hair styling tool that integrates combing and styling functions, are gradually gaining popularity among consumers. They generate steam by heating water in the tank and directing it to the comb teeth, allowing the hair to be moisturized and styled while combing, effectively reducing frizz and improving hairstyle texture. They are especially suitable for various styling needs, such as straight and curly hair.

[0003] Existing steam combs typically integrate the water tank inside the comb body or allow for detachable connection, but this still presents several problems in practical use. On the one hand, some products use top-filling or fixed water tank designs, making it inconvenient to add water and difficult to completely drain and clean, which can easily lead to bacterial growth. On the other hand, while detachable water tanks are convenient for refilling, they generally suffer from complex connection structures, poor sealing of the plug-in joints, and a tendency to leak, affecting safety and user experience.

[0004] Furthermore, the lack of a reliable locking mechanism during the water tank connection process makes it prone to loosening due to vibration or accidental contact, posing a risk to its use. Additionally, traditional structures often neglect the effective extraction of residual water and the balancing of internal air pressure, leading to issues such as pump cavitation and unstable steam output.

[0005] This utility model was developed precisely because of the aforementioned shortcomings. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a detachable connection structure for a steam comb water tank that is easy to operate and has good stability.

[0007] This utility model is achieved through the following technical solution:

[0008] This utility model provides a detachable connection structure for a steam comb and water tank, including a comb body and a water tank for storing liquid. The comb body is provided with an installation groove for the water tank to be inserted laterally. A connector is provided in the installation groove. The water tank is provided with a socket and a socket channel. When the water tank is inserted into the installation groove, the connector can be inserted into the socket channel. A locking mechanism for locking or unlocking the water tank is provided between the comb body and the water tank.

[0009] As described above, the steam comb water tank has a detachable connection structure. The bottom of the water tank is provided with a snap-fit ​​part. The comb body has a locking hole in the mounting cavity corresponding to the snap-fit ​​part. The locking mechanism includes a locking mounting base connected to the comb body, a button piece slidably connected to the locking mounting base, a pusher piece connected to the button piece, and a locking piece slidably connected to the locking mounting base. The locking piece has snap-fit ​​teeth that extend from the locking hole and snap-fit ​​with the snap-fit ​​part when it moves upward. A first elastic member that pushes the locking piece to return to its original position is connected between the locking piece and the locking mounting base. The pusher piece has a first guide slope. The locking piece has a second guide slope that cooperates with the first guide slope, thereby pushing the locking piece to move upward when the pusher piece moves laterally. A second elastic member that pushes the button piece to return to its original position is provided between the button piece and the locking mounting base.

[0010] As described above, the steam comb water tank has a detachable connection structure. The water tank is equipped with a water suction hose. One end of the water suction hose is connected to the sleeve channel, and the other end is connected to a counterweight ball. The counterweight ball is equipped with a water suction channel that is connected to the water suction hose.

[0011] As described above, the detachable connection structure of the steam comb tank includes a socket with a self-sealing valve assembly that opens when the insertion tube is inserted into the socket channel and closes when the insertion tube is pulled out.

[0012] As described above, the detachable connection structure of the steam comb tank includes a self-sealing valve assembly comprising a sealing cylinder, a sealing ring, a sealing ball, and a third elastic element. The sealing ring covers the sealing cylinder and allows the insertion pipe to extend into it. The third elastic element is located between the sealing ball and the sealing cylinder and pushes the sealing ball against the sealing ring.

[0013] As described above, the steam comb water tank has a detachable connection structure, and the bottom of the water tank is provided with an inlet / outlet hole that communicates with the inner cavity.

[0014] As described above, the steam comb water tank has a detachable connection structure, and the bottom of the water tank is connected to a sealing gasket that covers the inlet and outlet holes. The sealing gasket is provided with a sealing boss that can block the inlet and outlet holes.

[0015] As described above, the detachable connection structure of the steam comb water tank has a self-sealing slit hole on the closed boss for gas to enter the interior of the water tank.

[0016] As described above, the steam comb tank has a detachable connection structure, and the comb body has a notch at the edge of the mounting cavity for gas to enter.

[0017] As described above, in the detachable connection structure of the steam comb water tank, after the water tank is inserted into the mounting slot, its exposed part smoothly transitions with the outer contour of the comb body to form a continuous smooth surface; the exposed part of the button smoothly transitions with the outer contours of the water tank and the comb body to form a continuous smooth surface.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. Achieving both quick disassembly and reliable sealing of the water tank: Through the horizontal insertion structure combined with the docking of the insertion pipe and the sleeve channel, along with the design of the self-sealing valve assembly and sealing spring seat, the water tank can be easily replaced. At the same time, the fluid passage is automatically opened and closed and sealed during the insertion and removal process, which effectively prevents water leakage and improves the safety and convenience of use.

[0020] 2. The locking mechanism is stable and reliable, and easy to operate: It adopts a sloped linkage locking mechanism, which can unlock the water tank by pressing the button. The structure is compact and the operation is smooth. The vertical locking method of the locking teeth and the locking part has strong anti-vibration ability, ensuring that the water tank is stable and will not fall off during use. It also supports one-handed operation, providing a good user experience.

[0021] 3. Optimized water storage and pressure balance design: The built-in counterweight ball guides the water suction hose to always be located at the bottom of the water tank, maximizing the extraction of residual water; the bottom inlet and outlet holes, combined with a soft pad structure with self-sealing gap holes, achieve efficient air intake and pressure stabilization while preventing leakage, taking into account multiple functions such as water addition, drainage, leak prevention and pressure balance, improving water resource utilization and system operation stability.

[0030] The utility model will be further described below with reference to the accompanying drawings:

[0031] The orientations described in this utility model specification, such as "up," "down," "left," "right," "front," and "back," are based on the orientations in the accompanying drawings and are intended to facilitate the description of the relationships between the various components. They do not indicate the unique or absolute positional relationships between the various components, but are merely one embodiment of the utility model and are not a limitation on its implementation.

[0032] This embodiment describes a detachable connection structure for a steam comb and water tank, including a comb body 1 and a water tank 2 for storing liquid, such as... Figure 2 As shown, the bottom of the comb body 1 is equipped with a comb tooth cover 14, which has comb teeth for combing hair. The comb body 1 generally contains a water pump 15 for drawing water. The inlet of the water pump 15 is connected to a water tank 2, and the outlet of the water pump 15 is connected to a boiler 16. The boiler 16 heats the water to produce steam, which is then output to the end face of the comb tooth cover 14, thereby achieving hair bending and styling through steam. Figures 2 to 6 As shown, the comb body 1 has an installation groove 10 for the horizontal insertion of the water tank 2. An insertion tube 11 is located within the installation groove 10. The water tank 2 has a socket 21 with a socket channel 210. When the water tank 2 is inserted into the installation groove 10, the insertion tube 11 can be inserted into the socket channel 210. A locking mechanism 3 for locking or unlocking the water tank 2 is provided between the comb body 1 and the water tank 2. This allows for convenient installation and disassembly of the water tank and facilitates water filling. This connection structure adopts a "lateral sliding in + mechanical locking" design concept. The user only needs to push the water tank horizontally into the installation groove to automatically complete the connection and mechanical fixation of the fluid passage. The insertion tube 11, as a fixed end interface, is located inside the comb body. Correspondingly, the socket 21 on the water tank has an axial centering guide function, guiding the insertion tube accurately into the socket channel 210 during insertion, ensuring reliable sealing. The locking mechanism 3 locks and releases the latching part 22 via a button operation. The entire process can be completed without tools and with one hand, significantly improving ease of use. This design is particularly suitable for small personal care appliances that require frequent water replenishment, balancing safety and user experience.

[0033] As a preferred option, such as Figures 4 to 6As shown, the bottom of the water tank 2 is provided with a snap-fit ​​part 22, and the comb body 1 is provided with a locking hole 12 corresponding to the snap-fit ​​part 22 at the mounting groove 10. The locking mechanism 3 includes a locking mounting base 31 connected to the comb body 1, a button 32 slidably connected to the locking mounting base 31, a pusher 33 connected to the button 32, and a locking member 34 slidably connected to the locking mounting base 31. The locking member 34 is provided with a part that extends out of the locking hole 12 and engages with the snap-fit ​​part when it moves upward. The locking mechanism includes a locking tooth 341 for engaging the locking part 22. A first elastic element 35, which pushes the locking part 34 upwards, connects the locking member 34 to the locking mounting base 31. A first guide slope 330 is provided on the pushing member 33. A second guide slope 340, which cooperates with the first guide slope 330, pushes the locking member 34 upwards when the pushing member 33 moves laterally. A second elastic element 36, which pushes the button member 32 to its lateral reset position, connects the button member 32 to the locking mounting base 31. When the water tank 2 is inserted into the mounting cavity 10, the locking tooth 341 passes through the locking hole 12 and engages the locking part 22, thus locking the water tank 2. When the water tank 2 needs to be disassembled, pressing the button member 32 causes the locking tooth 341 to retract from the locking hole 12, unlocking the water tank. This locking mechanism uses a "slope drive + vertical latch" linkage principle. In the initial state, the first elastic element 35 (such as a compression spring) pushes the locking element 34 upward, causing the locking teeth 341 to extend out of the locking hole 12. When the water tank is inserted into place, the locking part 22 is positioned just above the locking teeth and is immediately locked. When the button 32 is pressed, it drives the pushing element 33 to move laterally. The first guide slope 330 and the second guide slope 340 press against each other, forcing the locking element 34 to move downward against the elastic force of the first elastic element 35, thereby disengaging the locking teeth 341 from the locking part 22, allowing the water tank to be easily pulled out. After the button is released, the second elastic element 36 resets the button 32, preparing for the next locking. This structure has clear action and definite feedback, and the parts are all conventional injection molded or stamped parts, which is conducive to mass production. It achieves "one-click unlocking", making operation labor-saving and efficient; the inclined transmission ratio is adjustable, and the pressing force can be optimized according to the feel requirements; the vertical locking method has high tensile strength and can effectively resist vibration and impact during use; all moving parts are integrated into the locking mounting base 31, with a compact structure and high space utilization.

[0034] As a preferred option, such as Figure 2 and Figure 7As shown, the water tank 2 is equipped with a water suction hose 23. One end of the water suction hose 23 is connected to the connecting channel 210, and the other end is connected to a counterweight ball 24. The counterweight ball 24 has a water suction channel 240 that communicates with the water suction hose 23. During use, the weight of the counterweight ball 24 ensures that the water inlet is always located at the bottom of the water tank cavity. The counterweight ball 24 is made of a metal material with a density greater than water (such as stainless steel) and always faces the bottom of the water tank due to its own weight. Regardless of the tilt angle of the water tank, the counterweight ball at the end of the water suction hose will sink synchronously with the drop in liquid level, ensuring that the water inlet is always submerged in water, maximizing the extraction of remaining water and reducing waste. This improves water utilization and avoids air suction caused by tilting; it requires no additional sensors or complex structures, is low in cost, and highly reliable; it is particularly suitable for scenarios where the product is used at different angles on the human body.

[0035] As a preferred option, such as Figure 2 and Figure 7 As shown, to improve the sealing performance of the water tank 2, the socket 21 is equipped with a self-sealing valve assembly 25 that opens when the connector 11 is inserted into the socket channel 210 and closes when the connector 11 is pulled out, thus maintaining a seal when the water tank is inserted or removed. Specifically, the self-sealing valve assembly 25 includes a sealing cylinder 251, a sealing ring 252, a sealing ball 253, and a third elastic element 254. The sealing ring 252 covers the sealing cylinder 251 and allows the connector 11 to extend into it. The third elastic element 254 is located between the sealing ball 253 and the sealing cylinder 251 and pushes the sealing ball 253 against the sealing ring 252. The self-sealing valve assembly 25 is a normally closed one-way shut-off valve. When not connected, the third elastic element 254 (such as a small spring) pushes the sealing ball 253 tightly against the inner end face of the sealing ring 252, forming an effective seal and preventing liquid leakage from the water tank. When the connector 11 is inserted, its front end pushes open the sealing ball 253, compresses the third elastic element 254, opens the flow channel, and allows water to flow. When pulled out, the elastic restoring force causes the sealing ball to press the sealing ring again, cutting off the passage. This achieves true "plug and play, pull and seal" functionality, eliminating leakage problems when replacing the water tank. The mating surfaces of the sealing ball and sealing ring can use a combination of soft and hard materials (such as a rubber ball + metal ring) for better sealing performance. The structure is simple, has a long service life, and is suitable for repeated insertion and removal applications.

[0036] As a further preferred option, such as Figure 2As shown, the insertion tube 11 is fitted with a sealing spring seat 111, which is connected to a fourth elastic element 112. The fourth elastic element 112 pushes the sealing spring seat 111 against the socket 21, further improving the fit stability and sealing performance. The sealing spring seat 111 is typically a floating sleeve structure with a lip seal ring. The fourth elastic element 112 (such as a coil spring) applies a preload to press it against the end face of the socket 21, forming a secondary dynamic seal. Even with assembly tolerances or slight wear, the elastic compensation mechanism can still maintain a good sealing state. The multi-seal design enhances the waterproof rating and adapts to high-temperature and high-humidity working environments; the elastic compression seal reduces hard contact damage and extends service life; it improves the insertion and removal feel, provides moderate damping, and enhances the quality of operation.

[0037] For ease of adding and draining water, such as Figure 7 As shown, the bottom of the water tank 2 is provided with an inlet / outlet hole 26 communicating with the inner cavity. Preferably, as... Figure 8 As shown, the bottom of the water tank 2 is connected to a sealing gasket 27 that covers the inlet / outlet hole 26. The sealing gasket 27 has a sealing boss 271 that can block the inlet / outlet hole 26. The sealing boss 271 has a self-sealing slit hole 272 for gas to enter the water tank 2. The sealing gasket 27 is made of materials such as rubber and silicone, so the self-sealing slit hole 272 is a small slit, which is self-sealed by water pressure when the water tank 2 stores water. When the water tank 2 is inserted, air intake and pressure stabilization are achieved through the self-sealing slit hole 272. In order to cooperate with air intake, the comb body 1 has a notch 101 at the edge of the mounting cavity 10 for gas to enter. The inlet / outlet hole 26 and the sealing gasket 27 form a simple but efficient two-way opening and closing structure. When adding water, the user can press the sealing gasket 27 lightly with his / her finger to deform it, and the sealing boss 271 will disengage from the inlet / outlet hole 26, so that clean water can be injected; the same operation is used to drain the water. The self-sealing slit hole 272 closes due to material rebound in a static state, preventing leakage. When negative pressure is generated inside the water tank (such as when a water pump draws water), external air enters the water tank through the notch 101 and the self-sealing slit hole 272, balancing the internal and external air pressure and ensuring continuous water supply. The bottom inlet and outlet design facilitates thorough cleaning and drainage, preventing bacterial growth. The self-sealing slit hole eliminates the need for an additional valve structure, reducing costs while achieving automatic ventilation. The notch 101 and the slit hole work together to form a stable air intake path, avoiding air resistance that could affect pumping efficiency.

[0038] As a preferred embodiment, after the water tank 2 is inserted into the mounting cavity 10, its exposed portion smoothly transitions with the outer contour of the comb body 1, forming a continuous, smooth surface; similarly, the exposed portion of the button 32 smoothly transitions with the outer contours of both the water tank 2 and the comb body 1, forming a continuous, smooth surface. This integrated design not only enhances the product's industrial aesthetics but, more importantly, eliminates sharp edges and gaps that are prone to dust accumulation and difficult to clean, meeting the high hygiene requirements of personal care products. Simultaneously, the smooth curved transition contributes to comfortable grip and reduces hand fatigue from prolonged use. The concealed layout of the button 32 also avoids the risk of accidental activation, enhancing overall safety and durability.
