Description

Technical Field

[0001] This utility model specifically relates to a steam styling comb. Background Technology

[0002] With the continuous development of personal care appliances, hairbrushes with steam functions are gaining popularity among consumers because they can gently care for hair while combing, improve frizz, and enhance smoothness. Existing steam styling brushes typically include components such as the brush body, built-in boiler, water tank, water pump, and control system. By heating water to generate steam, which is then sprayed out from the brush area, it achieves deep moisturization and styling of the hair.

[0003] However, traditional steam combs still have many shortcomings in their structural design. First, most products use top-filling or fully enclosed water tanks, making water filling inconvenient. Furthermore, the water tanks are either non-removable or complex to assemble and disassemble, affecting the daily user experience. Some detachable water tank structures lack reliable sealing mechanisms, making them prone to leakage during insertion and removal, contaminating the internal circuitry of the main unit and posing safety hazards. Second, the connection between the water tank and the main unit often relies on simple plugs or clips, resulting in poor locking reliability. During use, they are prone to loosening due to vibration or tilting, affecting the continuity of water supply. In addition, to generate steam, multiple functional components such as water pumps, boilers, and control modules are required. If the layout is unreasonable, the comb body can easily become bulky and unbalanced, affecting hand comfort and aesthetics.

[0004] More importantly, in existing products, functional modules are often clustered inside the comb body, lacking proper space planning. This results in a loose structure, difficult assembly, and hinders miniaturization and lightweight design. Furthermore, the proximity of high-temperature components such as the boiler to the water system and electrical control system leads to poor thermal management, causing water in the tank to evaporate due to heat or components to age, reducing the overall lifespan of the machine. In addition, the fixed water inlet makes it prone to cavitation when the tank is tilted, causing the water pump to run dry and be damaged. Complex air intake structures or poor sealing also frequently lead to air blockage or leakage problems.

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

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a steam styling comb that is compact in structure, easy to operate, and improves stability and safety.

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

[0008] This utility model provides a steam styling comb, including a comb body, an upper shell, a mounting bracket connected to the lower part of the upper shell, and a comb cover connected to the lower part of the mounting bracket. The comb cover has protruding comb teeth. The mounting bracket has a boiler assembly for generating steam. The boiler assembly has an outlet end that penetrates the comb cover and is used to output steam. A water tank is detachably connected to the comb body. The upper shell includes a comb cover, a connecting post connected to the comb cover, and a handle connected to the top of the connecting post. A water pump is installed in the connecting post. The water pump inlet is connected to the water tank, and the water outlet is connected to the water inlet of the boiler assembly. The handle has a control module electrically connected to the water pump to control the operation of the water pump, and a button module electrically connected to the control module for user operation.

[0009] As described above, the steam shaping comb has a first recessed cavity at the bottom of the mounting frame for installing boiler components and a second recessed cavity on the side for installing a water tank. The comb body cover is installed above the mounting frame from top to bottom, and the side of the comb body cover has an opening for the water tank to enter the second recessed cavity.

[0010] As described above, the steam styling comb has a connecting pipe for connecting a water tank in the second concave cavity. The water tank has a socket with a socket channel. When the water tank is inserted into the second concave cavity, the connecting pipe 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.

[0011] As described above, the steam styling comb has a water tank equipped with a water suction hose. One end of the water suction hose is connected to the connecting channel, and the other end is connected to a counterweight ball. The counterweight ball has a water suction channel that is connected to the water suction hose.

[0012] As described above, the steam molding comb has a socket assembly that opens when the insert pipe is inserted into the socket channel and closes when the insert pipe is pulled out.

[0013] As described above, in the steam shaping comb, a rubber sleeve is fitted on the steam outlet end of the boiler assembly, and the comb cover has a channel through which the rubber sleeve passes.

[0014] As described above, in a steam styling comb, the comb teeth are arranged around the air outlet end.

[0015] As described above, the steam-shaped comb has teeth consisting of a root section and an end section, both of which are tapered and gradually decrease in size from the proximal end to the distal end.

[0016] As described above, the bottom of the water tank is provided with an inlet and outlet hole that communicates with the inner cavity. The bottom of the water tank is connected to a sealing pad that covers the inlet and outlet hole. The sealing pad is provided with a sealing boss that can block the inlet and outlet hole. The sealing boss has a self-sealing gap hole to allow external air to enter the water tank to balance the pressure when the water pump is working.

[0017] As described above, in the steam-shaped comb, after the water tank is inserted into the second concave cavity, its exposed part smoothly transitions with the outer contour of the comb body cover, together forming a continuous curved contour.

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

[0019] 1. Highly integrated components and compact layout effectively reduce overall size: By embedding the water pump inside the connecting column, installing the boiler assembly in the first recess at the bottom of the mounting bracket, and horizontally inserting the water tank into the second recess on the side, a three-dimensional modular layout that coordinates vertical and horizontal movement is formed. This fully utilizes the internal space of the comb body, avoids the volume expansion caused by the stacking of functional components, significantly improves structural compactness, and enables the product to have a smaller and lighter appearance while ensuring functional integrity, making it easy to handle and store.

[0020] 2. The combination of side-mounted water tank and self-sealing structure achieves a compact and quick-release design: The water tank is inserted and installed along the side of the comb body. With the plug-in pipe and self-sealing valve assembly, the plug-and-play connection method eliminates the need for a top opening or complex pipeline docking, simplifying the fluid connection path and achieving reliable water supply and leak-proof sealing in a limited space. This side-mounted quick-release structure saves vertical space, eliminating the need for a pre-reserved water filling opening on the upper shell, further supporting the overall miniaturization and integrated appearance design.

[0021] 3. Functional modules are arranged in separate zones, and thermal management and ergonomics are coordinated and optimized: The boiler components are located in an independent bottom cavity, physically isolated from the upper water tank and handle area, reducing heat conduction to the grip area; the control module and buttons are centrally located in the handle, with short electrical wiring and fast signal response; the locking mechanism is integrated into the mounting base, with a closed structure and small footprint. The whole unit achieves separation and close linkage of four zones: "heat zone, water zone, electrical control zone, and operation zone," ensuring safe and stable operation while maximizing space utilization, making the product structure more compact and the operation more efficient.

[0031] The utility model will be further described below with reference to the accompanying drawings:

[0032] 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.

[0033] This embodiment introduces a steam styling comb, such as Figures 1 to 7As shown, the invention includes a comb body 100, which includes an upper shell 1, a mounting bracket 2 connected below the upper shell 1, and a comb cover 3 connected below the mounting bracket 2. The comb cover 3 has protruding comb teeth 31. The mounting bracket 2 has a boiler assembly 4 for generating steam. The boiler assembly 4 has an outlet end 41 that penetrates the comb cover 3 and is used to output steam. The invention can refer to the patent structure of the invention previously filed with patent number CN202420276517.2 entitled "A Small Boiler Heating Chamber Structure". The heating structure can heat water to produce steam and spray it out from the outlet end 41. A water tank 5 is detachably connected to the comb body 100. The upper shell 1 includes a comb cover 11, a connecting post 12 connected to the comb cover 11, and a handle 13 connected to the top of the connecting post 12. A water pump 6 is installed inside the connecting post 12. The water pump 6 has its inlet end connected to the water tank 5 and its outlet end connected to the inlet end of the boiler assembly 4. The handle 13 has a control module 7 electrically connected to the water pump 6 to control its operation and a button module 8 electrically connected to the control module 7 for user operation. This structure allows for a more compact arrangement of electrical components and functional parts, and the water tank is detachable, making it more convenient to use. This steam styling comb adopts a fluid dynamic path of "water tank → water pump → boiler → steam output". After receiving user instructions, the control module 7 drives the water pump 6 to draw water from the water tank 5 and deliver it to the boiler assembly 4 for instantaneous heating and vaporization, generating high-temperature steam which is then introduced into the comb tooth area through the steam outlet 41, achieving the function of combing and steam conditioning simultaneously. The entire system is integrated within the comb body 100. Its modular design achieves clear functional zoning and a rational layout. In particular, the water pump 6 is placed within the connecting column 12, fully utilizing vertical space and avoiding lateral expansion that would increase size, significantly improving handheld comfort and structural compactness. The control module 7 integrates a microcontroller, power management unit, and safety protection circuits (such as overheat protection and water shortage detection) to ensure stable and reliable operation. This structure achieves a rapid "instant steam" response; users can obtain continuous and stable steam output with a single button press using the button module 8. The detachable water tank 5 facilitates water addition, cleaning, and replacement, greatly improving the convenience and hygiene of daily use. The overall layout physically isolates the high-heat-generating components (boiler assembly 4) from the operating area (handle 13), effectively preventing heat conduction to the grip area and enhancing safety.

[0034] As a preferred option, such as Figure 3 and Figure 4As shown, the mounting frame 2 has a first recess 21 at the bottom for mounting the boiler assembly 4 and a second recess 22 on the side for mounting the water tank 5. The comb cover 11 covers the mounting frame 2 from top to bottom, and the side of the comb cover 11 has a clearance opening 111 for the water tank 5 to enter the second recess 22. The first recess 21 provides a precise positioning and thermal isolation space for the boiler assembly 4, and its inner wall can be provided with heat insulation material or air gaps to reduce heat transfer to the outer shell. The second recess 22 is arranged laterally on the side of the mounting frame 2, forming an independent water tank receiving area, separated from the boiler area, to avoid the high temperature affecting the stability of the water quality in the water tank. The clearance opening 111 allows the water tank 5 to be inserted horizontally from the side, which conforms to ergonomic operating habits and facilitates installation and removal with one hand. The side-plugged water tank structure avoids sealing problems and structural strength reduction caused by top openings; the dual-chamber partition design separates the "hot zone" and "cold zone", improving thermal management efficiency and overall machine safety; the comb cover 11 overall cover structure enhances the integrated appearance, while providing mechanical protection and dustproof function.

[0035] As a preferred option, such as Figures 5 to 7As shown, the second recess 22 is provided with a connector 23 for connecting the water tank 5. The water tank 5 is provided with a socket 51, which has a socket channel 510. When the water tank 5 is inserted into the second recess 22, the connector 23 can be inserted into the socket channel 510. A locking mechanism 9 for locking or unlocking the water tank 5 is provided between the comb body 100 and the water tank 5. In detail, the bottom of the water tank 5 is provided with a snap-fit ​​part 57. The comb body 100 is provided with a locking hole 24 in the second recess 22 corresponding to the snap-fit ​​part 57. The locking mechanism 9 includes a locking mounting base 91 connected to the comb body 100, a button 92 slidably connected to the locking mounting base 91, a pusher 93 connected to the button 92, and a locking member 94 slidably connected to the locking mounting base 91. The locking member 94 is provided with a feature that extends out of the locking hole 24 and connects with the locking hole 24 when it moves upward. The locking part 57 engages with the locking teeth 941. A first elastic element 95, which pushes the locking member 94 upwards, connects the locking member 94 to the locking mounting base 91. The pushing member 93 has a first guide slope 930, and the locking member 94 has a second guide slope 940 that cooperates with the first guide slope 930, causing the locking member 94 to move upwards when the pushing member 93 moves laterally. A second elastic element 96, which pushes the button member 92 to move laterally, connects the button member 92 to the locking mounting base 91. When the water tank 5 is inserted into the second recess 22, the locking teeth 941 pass through the locking hole 24 and engage with the locking part 57 to lock the water tank 5. When the water tank 5 needs to be disassembled, pressing the button member 92 causes the locking teeth 941 to retract from the locking hole 24 through the linkage between the pushing member 93 and the locking member 94, thus unlocking the water tank. This locking mechanism adopts a "slope drive + vertical latch" linkage principle. In the initial state, the first elastic element 95 (such as a compression spring) pushes the locking element 94 upward, causing the locking teeth 941 to extend out of the locking hole 24. When the water tank is inserted into place, the locking part 57 is exactly above the locking teeth and is immediately locked. When the button 92 is pressed, it drives the pushing element 93 to move laterally. The first guide slope 930 and the second guide slope 940 press against each other, forcing the locking element 94 to move downward against the elastic force of the first elastic element 95, thereby disengaging the locking teeth 941 from the locking part 57, at which point the water tank can be easily pulled out. After the button is released, the second elastic element 96 resets the button 92, preparing for the next locking. This structure has clear action and clear 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 91, with a compact structure and high space utilization.

[0036] As a preferred option, such as Figure 2 and Figure 8 As shown, the water tank 5 is equipped with a water suction hose 52. One end of the water suction hose 52 is connected to the connecting channel 510, and the other end is connected to a counterweight ball 53. The counterweight ball 53 has a water suction channel 530 that communicates with the water suction hose 52. During use, the weight of the counterweight ball 53 ensures that the water inlet is always located at the bottom of the water tank cavity. The counterweight ball 53 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.

[0037] As a preferred option, such as Figure 2 and Figure 8 As shown, the socket 51 is equipped with a self-sealing valve assembly 54 that opens when the connector 23 is inserted into the socket channel 510 and closes when the connector 23 is pulled out. Specifically, the self-sealing valve assembly 54 includes a sealing cylinder 541, a sealing ring 542, a sealing ball 543, and a third elastic element 544. The sealing ring 542 covers the sealing cylinder 541 and allows the connector 23 to extend into it. The third elastic element 544 is located between the sealing ball 543 and the sealing cylinder 541 and pushes the sealing ball 543 against the sealing ring 542. The self-sealing valve assembly 54 is a normally closed one-way shut-off valve. When not connected, the third elastic element 544 (such as a small spring) pushes the sealing ball 543 tightly against the inner end face of the sealing ring 542, forming an effective seal to prevent liquid leakage from the water tank. When the connector 23 is inserted, its front end pushes open the sealing ball 543, compresses the third elastic element 544, opens the flow channel, and allows water flow. When pulled out, the elastic restoring force causes the sealing ball to press against the sealing ring again, cutting off the passage. This achieves true "plug and play, plug and seal," 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 plugging and unplugging applications. This self-sealing valve assembly 54 uses a mechanical passive opening mechanism, requiring no external energy drive, resulting in rapid response and a low failure rate. The pre-pressure of the third elastic element 544 needs to be precisely designed to ensure sealing reliability without causing excessive insertion resistance. The sealing ball 543 can be made of elastic rubber or silicone to improve the sealing surface fit; the inner hole of the sealing ring 542 can have a tapered guide structure to facilitate smooth insertion of the connector and guide the displacement of the sealing ball.

[0038] As a preferred option, such as Figure 5As shown, a rubber sleeve 42 is fitted onto the air outlet end 41 of the boiler assembly 4, and a channel is provided on the comb cover 3 for the rubber sleeve 42 to pass through. The comb teeth 31 are arranged around this channel. The rubber sleeve 42 can insulate against heat and prevent the high temperature of the boiler assembly 4 from contacting the human body. The rubber sleeve 42 not only serves as heat insulation but also has a buffering and sealing function, preventing high-temperature steam from leaking out along the gap between the air outlet end 41 and the comb cover 3, thus improving thermal efficiency and safety. The rubber material is preferably high-temperature resistant silicone (resistant to temperatures above 150℃), which has good elasticity and long-term stability. This design achieves physical isolation between high-temperature components and the external environment, meeting the safety standards for personal care appliances.

[0039] As a preferred option, such as Figure 1 and Figure 2 As shown, the comb teeth 31 consist of a root section 311 and a tip section 312, both of which are tapered, gradually decreasing in size from proximal to distal. This tapered design makes it easier for the comb teeth to penetrate the hair strands during combing, reducing pulling and breakage. The thicker root section 311 provides sufficient structural strength to prevent bending; the slender, rounded tip section 312 enhances comfort and prevents scalp abrasion. The overall design is ergonomic and suitable for various hair types, providing a particularly good combing experience for fine, soft, or easily tangled hair.

[0040] As a preferred option, for ease of water addition and drainage, such as Figure 8 As shown, the bottom of the water tank 5 is provided with an inlet / outlet hole 55 communicating with the inner cavity. Preferably, as... Figure 9As shown, the bottom of the water tank 5 is connected to a sealing gasket 56 that covers the inlet / outlet hole 55. The sealing gasket 56 has a sealing boss 561 that can block the inlet / outlet hole 55. The sealing boss 561 has a self-sealing slit hole 562 for gas to enter the water tank 5. The sealing gasket 56 is made of materials such as rubber and silicone, so the self-sealing slit hole 562 is a small slit, which is self-sealed by water pressure when the water tank 5 stores water. When the water tank 5 is inserted, air intake and pressure stabilization are achieved through the self-sealing slit hole 562. In order to cooperate with the air intake, the comb body 1 has a notch 220 at the edge of the second cavity 22 for gas to enter. The inlet / outlet hole 55 and the sealing gasket 56 form a simple but efficient two-way opening and closing structure. When adding water, the user can press the sealing gasket 56 lightly with his / her finger to deform it, and the sealing boss 561 will disengage from the inlet / outlet hole 55, so that clean water can be injected; the same operation is used to drain the water. The self-sealing slit hole 562 closes due to material rebound when stationary, 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 220 and the self-sealing slit hole 562, 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 venting. The notch 220 and the slit hole work together to form a stable air intake path, avoiding air resistance that could affect pumping efficiency.

[0041] Preferably, after the water tank 5 is inserted into the second recess 22, its exposed portion smoothly transitions with the outer contour of the comb cover 11, forming a continuous curved contour. 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 92 also avoids the risk of accidental activation, enhancing overall safety and durability. This integrated curved design utilizes a one-piece molding process, and the surface can be matte or anti-slip treated to improve texture and anti-slip performance. The high degree of contour matching between the water tank and the main unit creates a visually seamless effect, enhancing the premium feel. The concealed button design prevents accidental activation of the device during placement or storage, extending battery life and improving safety.
