Automatic liquid discharging massage comb

Abstract

The application provides an automatic liquid discharging massage comb, which comprises a massage comb shell, a driving member and a liquid discharging structure. The driving member is installed on the massage comb shell, and the liquid discharging structure comprises a gear set, a compression roller and a flexible conduit. The gear set has an input gear and an output gear. The driving member is in driving connection with the input gear, so that power is transmitted to the gear set; the output gear is in driving connection with the compression roller, so that the compression roller can move synchronously with the rotation of the gear set. One end of the flexible conduit is a liquid inlet, and the other end is a liquid outlet. The flexible conduit is used for forming a liquid conveying channel. When the driving member is started, the motor power is transmitted to the compression roller through the input gear and the output gear in sequence, so as to drive the roller to make circular motion. The roller periodically extrudes the wall of the flexible conduit during rotation, so as to generate a continuous peristaltic pump effect, force the liquid in the tube to move from the liquid inlet to the liquid outlet in a directional manner, and finally uniformly seep out through the liquid guide holes of the comb teeth.

Description

Technical Field

[0001] This application belongs to the field of massage comb technology, and more specifically, relates to an automatic liquid dispensing massage comb. Background Technology

[0002] Traditional massage combs stimulate acupoints on the scalp with mechanical comb teeth to promote local blood circulation, while integrated liquid dispensing functions further deliver active ingredients such as care lotion or essential oils to the hair follicle area, thereby achieving multiple effects in terms of cleansing, nourishing, or treatment.

[0003] In existing technologies, the liquid dispensing of massage combs primarily relies on a rolling steel ball at the tip of the liquid guide column. When the column contacts the scalp, the steel ball is displaced under pressure, causing the liquid stored inside the comb to slowly seep out through the liquid guide channel. Because the dispensing process depends entirely on the user's applied angle and force, it's difficult to guarantee uniform liquid distribution. Especially when used non-vertically, uneven contact pressure between the steel ball and the liquid guide channel can easily cause liquid interruption or excessive overflow. This not only affects the user experience but may also reduce the therapeutic effect due to uneven liquid distribution. Utility Model Content

[0004] The purpose of this application is to provide an automatic liquid dispensing massage comb to solve the technical problem of poor liquid dispensing effect of massage combs in the prior art.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

The driving component is driven to the input gear, and the pressure roller is driven to the output gear. One end of the flexible conduit is a liquid inlet, and the other end is a liquid outlet. When the pressure roller rotates, it periodically presses against the flexible conduit to squeeze the liquid inside the flexible conduit to move from the liquid inlet to the liquid outlet and flow out from the liquid outlet.

[0011] Optionally, the liquid outlet structure further includes a liquid distribution plate, which has a liquid guiding hole and a liquid guiding groove. The liquid guiding hole is connected to the liquid outlet, and each of the liquid guiding grooves is arranged radially outward from the liquid guiding hole.

[0012] Optionally, the liquid outlet structure further includes a liquid outlet shell, and the liquid distribution plate is disposed inside the liquid outlet shell; the liquid outlet shell has a plurality of liquid guiding columns, the inlet end of each liquid guiding column is connected to the corresponding liquid guiding groove, and the outlet end of each liquid guiding column is used to discharge liquid to the external working surface.

[0013] Optionally, the gear set further includes a first reduction gear and a second reduction gear, the input gear meshes with the first reduction gear, the first reduction gear and the second reduction gear are coaxially arranged, and the second reduction gear meshes with the output gear.

[0014] Optionally, the gear set further includes a one-way bearing, the outer ring of which is connected to one of the first reduction gear and the second reduction gear, and the inner ring of which is connected to the other of the first reduction gear and the second reduction gear.

[0015] When the first reduction gear rotates forward, the one-way bearing drives the second reduction gear to rotate; when the first reduction gear rotates in reverse, the one-way bearing stops driving the second reduction gear to rotate.

[0016] Optionally, the liquid outlet structure further includes an upper cover, a middle cover, and a lower cover connected in sequence. The upper cover and the middle cover enclose a first receiving cavity, and the upper cover, the middle cover, and the lower cover also enclose a second receiving cavity. The input end gear and the first reduction gear are disposed in the first receiving cavity, and the second reduction gear, the output end gear, the pressure roller, and at least part of the flexible conduit are disposed in the second receiving cavity.

[0017] The liquid distribution plate and the lower cover enclose a liquid outlet cavity, and the flexible conduit is connected to the liquid outlet cavity.

[0018] Optionally, it also includes a transmission component rotatably connected to the massage comb housing, the transmission component having a first engagement portion and a second engagement portion, the first engagement portion being drivenly connected to a drive component, and the second engagement portion being drivenly connected to the input end gear.

[0019] Optionally, it also includes a comb assembly, which includes a comb base and comb teeth. The comb base is connected to the massage comb housing, and the comb base has an opening through which the liquid outlet extends. The comb teeth are movably connected to the comb base.

[0020] The transmission component is also provided with a track groove, one end of the comb teeth extends into the track groove and is slidably connected to the track groove; when the transmission component rotates, the other end of the comb teeth alternately swings towards or away from the axis of the opening.

[0021] Optionally, the number of comb teeth is multiple, and each comb tooth is arranged at intervals from each other along the circumference of the opening.

[0022] Optionally, the liquid outlet structure further includes a liquid storage component with a liquid storage chamber, the liquid storage component being connected to the upper cover, the liquid storage chamber having a liquid supply port and an openable / closable liquid replenishment port, the liquid supply port being connected to the liquid inlet of the flexible conduit.

[0023] The beneficial effects of the massage comb provided in this application are as follows:

[0024] The automatic liquid-dispensing massage comb provided in this application includes a massage comb housing, a drive unit, and a liquid dispensing structure. The drive unit is mounted on the massage comb housing and provides power output. The liquid dispensing structure includes a gear set, a pressure roller, and a flexible conduit. The gear set has an input gear and an output gear. The drive unit is driven by the input gear, transmitting power to the gear set; the output gear is driven by the pressure roller, allowing the pressure roller to move synchronously with the rotation of the gear set. The pressure roller specifically includes a support and multiple needle rollers, each needle roller being evenly distributed at a certain interval around the axial direction of the support to ensure that the pressure roller applies uniform pressure to the flexible conduit during rotation. The pressure roller and the output gear are coaxially arranged, allowing the pressure roller to rotate synchronously with the rotation of the output gear, thereby achieving efficient power transmission. One end of the flexible conduit is a liquid inlet, and the other end is a liquid outlet; the flexible conduit forms a liquid delivery channel. When the drive unit is activated, the motor power is transmitted sequentially to the pressure roller through the input gear and the output gear, driving the needle rollers to perform circular motion. During rotation, the needle roller periodically squeezes the wall of the flexible conduit, generating a continuous peristaltic pump effect. This forces the liquid inside the tube to move directionally from the inlet to the outlet, and finally seeps out evenly through the guide holes in the comb section. By adjusting the rotation speed of the drive component, the rotation frequency of the pressure roller can be precisely controlled, thereby achieving linear regulation of the liquid flow rate.

[0025] The automatic liquid dispensing massage comb of this application not only overcomes the dependence of traditional steel ball-type liquid dispensing devices on the angle of force application, but also ensures that it can maintain constant liquid dispensing stability under different usage postures, thereby improving the practicality and reliability of the massage comb.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0040] To address the issues of uneven liquid dispensing and poor liquid dispensing effect in existing massage combs, such as... Figures 1 to 3 As shown, this application provides an automatic liquid dispensing massage comb, which includes a massage comb housing 1, a drive component 2, and a liquid dispensing structure 3.

[0041] The massage comb housing 1 serves as the main support structure of the overall structure, used to accommodate and fix other functional components; the drive unit 2 is installed on the massage comb housing 1 to provide power output, specifically using a motor as the drive source to achieve a stable and controllable power supply.

[0042] The liquid outlet structure 3 includes a gear set 31, a pressure roller 32, and a flexible conduit 33. The gear set 31 has an input gear 311 and an output gear 312. The driving component 2 is driven by the input gear 311, transmitting power to the gear set 31. The output gear 312 is driven by the pressure roller 32, allowing the pressure roller 32 to move synchronously with the rotation of the gear set 31. The pressure roller 32 specifically includes a support and multiple needle rollers, which are evenly distributed at certain intervals around the axial direction of the support to ensure that the pressure roller 32 applies uniform pressure to the flexible conduit 33 during rotation. The pressure roller 32 and the output gear 312 are coaxially arranged, allowing the pressure roller 32 to rotate synchronously with the output gear 312, thereby achieving efficient power transmission. One end of the flexible conduit 33 is a liquid inlet, and the other end is a liquid outlet; the flexible conduit 33 forms a liquid delivery channel.

[0043] When the drive unit 2 is started, the motor power is transmitted to the pressure roller 32 sequentially through the input gear 311 and the output gear 312, driving the needle roller to perform a circular motion. During the rotation, the needle roller periodically squeezes the wall of the flexible conduit 33, generating a continuous peristaltic pump effect, forcing the liquid inside the tube to move directionally from the inlet to the outlet, and finally seeping out evenly through the outlet end of the guide column 351. By adjusting the speed of the drive unit 2, the rotation frequency of the pressure roller 32 can be precisely controlled, thereby achieving linear regulation of the liquid flow rate.

[0044] The automatic liquid dispensing massage comb of this application not only overcomes the dependence of traditional steel ball-type liquid dispensing devices on the angle of force application, but also ensures that it can maintain constant liquid dispensing stability under different usage postures, thereby improving the practicality and reliability of the massage comb.

[0045] like Figure 3 As shown, in a specific embodiment of this application, the liquid outlet structure 3 further includes a liquid distribution plate 34, which has liquid guiding holes 343 and liquid guiding grooves 341. The liquid guiding holes 343 are connected to the liquid outlet of the flexible conduit 33, and each liquid guiding groove 341 is arranged radially and uniformly outward from the liquid guiding hole 343 to ensure that the liquid flowing from the outlet can be evenly distributed to various areas of the liquid distribution plate 34, thereby improving the liquid distribution efficiency and usage effect.

[0046] like Figure 3 As shown, in a specific embodiment of this application, the liquid dispensing structure 3 further includes a liquid dispensing shell 35, and a liquid distribution plate 34 is specifically disposed within the liquid dispensing shell 35. The liquid dispensing shell 35 is provided with multiple liquid guiding columns 351, the inlet end of each liquid guiding column 351 being connected to a corresponding liquid guiding groove 341 on the liquid distribution plate 34, thereby forming a continuous channel for liquid to flow from the liquid guiding groove 341 to the liquid guiding column 351. The outlet end of each liquid guiding column 351 is used to contact the user's scalp to apply the liquid to the scalp.

[0047] like Figure 3 As shown, in a specific embodiment of this application, a sealing ring 342 is also connected to the side wall of the liquid dispensing tray 34. When the liquid dispensing tray 34 is installed inside the liquid outlet shell 35, the sealing ring 342 forms a sealing contact with the inner wall of the liquid outlet shell 35, thereby preventing leakage between the liquid dispensing tray 34 and the liquid outlet shell 35.

[0048] like Figure 2 As shown, in a specific embodiment of this application, the gear set 31 further includes a first reduction gear 313 and a second reduction gear 314. The input gear 311 is meshed with the first reduction gear 313, thereby transmitting the power input from the drive member 2 from the input gear 311 to the first reduction gear 313. The first reduction gear 313 and the second reduction gear 314 are coaxially arranged, and the first reduction gear 313 drives the second reduction gear 314 to rotate while rotating. The second reduction gear 314 is meshed with the output gear 312, thereby transmitting the power after two stages of reduction to the output gear 312. Through the two-stage reduction action of the two pairs of transmission gears, the gear set 31 can gradually reduce the high input speed of the drive member 2 to a speed range suitable for the operation of the pressure roller 32, which not only effectively reduces the speed of the output gear 312, but also improves the torque output during the transmission process, thereby ensuring that the squeezing action of the pressure roller 32 on the flexible guide tube 33 is more stable and reliable.

[0049] like Figure 2 As shown, in one specific embodiment of this application, the gear set 31 further includes a one-way bearing 36 for controlling the direction of power transmission. Specifically, the outer ring of the one-way bearing 36 is connected to one of the first reduction gear 313 and the second reduction gear 314, and the inner ring of the one-way bearing 36 is connected to the other of the first reduction gear 313 and the second reduction gear 314.

[0050] It should be noted that the transmission connection between the one-way bearing 36 and the first reduction gear 313 and the second reduction gear 314 includes, but is not limited to, direct contact connection, as well as indirect connection via a drive shaft or other means. The specific configuration is as follows:

[0051] When both the outer and inner rings of the one-way bearing 36 are cylindrical collars, with the inner ring positioned inside the outer ring, the outer ring of the one-way bearing 36 can be directly connected to the first reduction gear 313, and the inner ring of the one-way bearing 36 is connected to the drive shaft, transmitting torque to the second reduction gear 314 via the drive shaft. When the first reduction gear 313 rotates in a specified direction, the outer and inner rings of the one-way bearing 36 couple, thereby driving the drive shaft and the second reduction gear 314 to rotate. When the rotation direction of the first reduction gear 313 is opposite, the outer and inner rings of the one-way bearing 36 slide together, thus preventing the transmission of torque to the drive shaft and the second reduction gear 314.

[0052] Alternatively, the drive shaft is connected to both the first reduction gear 313 and the inner ring of the one-way bearing 36; the outer ring of the one-way bearing 36 is connected to the second reduction gear 314; when the first reduction gear 313 and the drive shaft rotate in a specified direction, the outer and inner rings of the one-way bearing 36 couple, thereby driving the second reduction gear 314 to rotate; when the rotation directions of the first reduction gear 313 and the drive shaft are opposite, the outer and inner rings of the one-way bearing 36 slide, thus preventing the torque from being transmitted to the second reduction gear 314.

[0053] Another configuration of the one-way bearing 36 includes an inner ring that mates with the outer ring, the outer diameter of which matches the inner diameter of the outer ring. The inner ring also includes an extension that extends axially outward from the outer ring. Two gears are connected to the outer ring and the inner ring extension of the one-way bearing 36, respectively, thus achieving both staggered arrangement of the two gears and unidirectional transmission between them, without the need for external parts such as a drive shaft.

[0054] When the first reduction gear 313 rotates forward, the one-way bearing 36 is engaged, driving the second reduction gear 314 to rotate as well. Since the second reduction gear 314 meshes with the output gear 312, and the output gear 312 is connected to the pressure roller 32, the second reduction gear 314, when rotating, drives the pressure roller 32 to rotate as well, thereby driving the liquid in the flexible conduit 33 to move from the inlet to the outlet, thus achieving automatic liquid delivery. When the first reduction gear 313 rotates in reverse, the one-way bearing 36 automatically disengages, stopping power transmission, causing the second reduction gear 314 to stop rotating. Similarly, this stops the automatic liquid delivery. It should be noted that the forward rotation direction of the first reduction gear 313 refers to the direction in which torque can be transmitted through the one-way bearing 36, and the reverse rotation direction refers to the direction in which torque cannot be transmitted through the one-way bearing 36. The forward / reverse rotation direction of the first reduction gear 313 does not refer to the clockwise or counterclockwise rotation direction controlled by the drive component 2.

[0055] like Figure 2As shown, in a specific embodiment of this application, the liquid outlet structure 3 further includes an upper cover 37, a middle cover 38, and a lower cover 39 connected in sequence. These three are fixedly connected by fasteners to form a complete shell structure. The upper cover 37 and the middle cover 38 enclose a first accommodating cavity for accommodating the input gear 311 and the first reduction gear 313. The upper cover 37, the middle cover 38, and the lower cover 39 also enclose a second accommodating cavity for accommodating the second reduction gear 314, the output gear 312, the pressure roller 32, and at least a portion of the flexible conduit 33. This compartmentalized structure not only enables a reasonable layout of the components but also effectively isolates different functional areas, avoiding mutual interference between components, thereby improving the stability of the structure and the reliability of operation.

[0056] The liquid distribution plate 34 and the lower cover 39 enclose a liquid outlet cavity. The flexible conduit 33 is connected to the liquid outlet cavity, so that the liquid can be transported to the liquid outlet cavity through the flexible conduit 33, and the liquid is evenly distributed and output through the liquid guide groove 341 on the liquid distribution plate 34 and the liquid guide column 351 on the liquid outlet shell 35.

[0057] like Figure 2 As shown, in one specific embodiment of this application, the liquid outlet structure 3 further includes a liquid storage component 310 with a liquid storage chamber. The liquid storage component is connected to the upper cover 37. The top of the liquid storage chamber is provided with a liquid replenishment port, which is equipped with a sealing rubber stopper or screw cap to achieve sealed storage and convenient replenishment of the liquid. The bottom of the liquid storage chamber is provided with a liquid supply port, which is connected to the liquid inlet of the flexible conduit 33 to ensure smooth flow of the liquid.

[0058] In actual operation, the user can first open the sealing cap of the replenishment port, inject the required amount of nursing solution into the storage chamber through the replenishment port, and then close the replenishment port to prevent liquid leakage. When the drive unit 2 is started, the liquid in the storage chamber flows naturally into the flexible conduit 33 through the supply port under the action of gravity, and then forms a directional flow under the periodic squeezing action of the pressure roller 32.

[0059] like Figure 1 and Figure 3 As shown, in one specific embodiment of this application, the automatic liquid-dispensing massage comb further includes a transmission component 4 rotatably connected to the massage comb housing 1. The transmission component 4 is specifically annular, having a first engaging portion 41 and a second engaging portion 42. The first engaging portion 41 is specifically located on the outer ring wall of the annulus and is driven by the driving component 2. The second engaging portion 42 is specifically located on the inner ring wall of the annulus and is driven by the input gear 311. The driving component 2 controls the forward or reverse rotation of the transmission component 4.

[0060] like Figure 1As shown, in one specific embodiment of this application, the automatic liquid dispensing massage comb further includes a comb tooth assembly 5. The comb tooth assembly 5 includes a comb tooth base 51 and a comb tooth group 52. The comb tooth base 51 is connected to the massage comb housing 1, and the comb tooth base 51 has an opening for the liquid dispensing structure 3 to pass through the comb tooth base 51. The comb tooth group 52 is movably connected to the comb tooth base 51.

[0061] The transmission component 4 is also provided with a track groove 43. One end of the comb tooth assembly 52 extends into the track groove 43 and is slidably connected to the track groove 43; the track groove 43 is used to guide the movement of the comb tooth assembly 52. ​​The other end of the comb tooth assembly 52 extends outward toward the comb tooth seat 51. When the transmission component 4 rotates, the other end of the comb tooth assembly 52 alternately swings toward the axis closer to or away from the opening to achieve a massage effect. The comb tooth assembly 52 includes an integrally formed connecting base and multiple spaced comb teeth, and the connecting base is movably connected to the comb tooth seat 51.

[0062] like Figure 1 As shown, in another specific embodiment of this application, there are multiple comb tooth groups 52, and each comb tooth group 52 is evenly spaced around the opening of the comb tooth seat 51 to ensure that the comb tooth group 52 covers a larger scalp area when it swings, thereby improving the massage effect and the comfort of use.

[0063] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
