The transmission gear set is provided with an input end gear and an output end gear, and the output end gear drives the pressing roller to rotate. And one end of the conduit is a liquid inlet, and the other end is a liquid outlet. And when the compression roller rotates, the outer surface of the compression roller is periodically pressed against the guide pipe, so that the liquid is conveyed from the liquid inlet to the liquid outlet and flows out from the liquid outlet.

Description

Technical Field

[0001] This application belongs to the technical field of massage combs, and more specifically, relates to a liquid discharging structure and a massage comb. Background Art

[0002] Traditional massage combs stimulate scalp acupoints through the mechanical movement of the comb teeth to promote local blood circulation, and the integrated liquid discharging function further transports active ingredients such as nursing liquids or essential oils to the hair follicle area, thus achieving multiple effects in terms of cleaning, nourishing or treating.

[0003] In the prior art, there are mainly two typical implementation schemes for the liquid delivery mechanism: one relies on passive liquid discharge by gravity, and a rolling steel ball is provided at the top of the liquid guide column. When the liquid guide column contacts the scalp during use, the steel ball is displaced under the action of pressure, so that the liquid stored inside the comb body slowly seeps out through the liquid guide channel. Although this scheme has a simple structure, the liquid discharge uniformity is significantly affected by the force application angle and strength of the user, and accurate flow control cannot be achieved. Especially in the non-vertical use state, liquid breakage or excessive overflow is likely to occur. The other relies on at least two motors to respectively control the vibration of the comb teeth and the active pumping of the liquid. Although it can improve the controllability of liquid discharge, multiple power sources lead to an increase in the product volume and energy consumption. At the same time, the complex mechanical structure raises the manufacturing cost and the risk of failure. Summary of the Invention

[0010] A one-way bearing is provided between the input end gear and the output end gear; when the input end gear rotates forward, the one-way bearing drives the input end gear to rotate to drive the pressure roller to rotate; when the input end gear rotates reversely, the one-way bearing stops driving the input end gear to rotate.

[0018] The present application also provides a massage comb, comprising:

[0019] case;

[0020] A transmission member is rotatably connected to the housing, and the transmission member has a first meshing portion, a second meshing portion and a track groove;

[0021] A driving member, mounted on the housing, drivingly connected to the first meshing portion to drive the transmission member to rotate forward or reverse;

[0022] The comb tooth assembly includes a comb tooth base and a comb tooth group. The comb tooth base is connected to the housing, and an opening is further provided on the comb tooth base. The comb tooth group is movably connected to the comb tooth base. One end of the comb tooth group extends into the track groove and is slidably connected to the track groove. When the transmission member rotates, the other end of the comb tooth group swings alternately in a direction close to or away from the axis of the opening.

[0023] The above-mentioned liquid outlet structure is connected to the housing and extends out through the opening of the comb tooth base 141. The input gear of the liquid outlet structure is drivingly connected to the second engagement portion.

[0024] When the driving member drives the transmission member to rotate forward, the comb tooth group swings on the comb tooth base, and the liquid outlet of the liquid outlet structure discharges liquid.

The light-emitting member is provided between the light-transmitting cover and the liquid outlet housing. The light-transmitting cover has a light-emitting surface, and the light-emitting member is arranged facing the light-emitting surface.

[0029] The beneficial effects of a liquid outlet structure and a massage comb provided by this application are as follows:

[0030] The liquid outlet structure provided by this application includes a transmission gear set, a pressure roller, a conduit, and a one-way bearing. The transmission gear set has an input-end gear and an output-end gear, where the input-end gear is used to receive external power input, and the output-end gear is used to drive the pressure roller to rotate. One end of the conduit is the liquid inlet, and the other end is the liquid outlet. When the pressure roller rotates, its outer surface periodically presses against the conduit, that is, each needle roller presses against the conduit in turn as the bracket rotates. Through the extrusion effect, a peristaltic effect is generated in the liquid in the conduit, so as to convey the liquid from the liquid inlet to the liquid outlet direction and flow out from the liquid outlet. The one-way bearing is arranged on the transmission path of the input-end gear and the output-end gear to control the power transmission direction of the transmission gear set. When the driving member of the massage comb drives the input-end gear to rotate forward, the one-way bearing enters the meshing state, transmits the power to the output-end gear, and drives the pressure roller to rotate synchronously. The needle rollers of the pressure roller sequentially squeeze the conduit wall during rotation, generating a continuous peristaltic pump effect, forcing the liquid in the tube to move directionally from the liquid inlet to the liquid outlet. At the same time, the driving member synchronously drives the comb tooth assembly to perform a massage action through the transmission mechanism, realizing the coordinated work of massage and liquid outlet. When the driving member of the massage comb drives the input-end gear to rotate reversely, the one-way bearing automatically disengages from the meshing state, interrupts the power transmission path, and keeps the output-end gear and the pressure roller in a static state. At this time, the liquid conveying process in the conduit terminates, while the comb tooth assembly still works normally, thus realizing a single massage function.

[0031] Without the need to be equipped with two power sources, the liquid outlet structure of this application can still realize at least two working modes and the switching between working modes, which not only simplifies the driving structure of the massage comb, but also improves the flexibility of function selection and improves the user experience.

[0032] The massage comb provided by this application includes the above liquid outlet structure, so it also has the advantages of the above liquid outlet structure. Description of the Drawings

[0046] The present invention will be further described in detail below in conjunction with the specific embodiments and the accompanying drawings.

[0047] In order to simplify the drive structure of the massage comb and be able to achieve multiple working modes, as Figure 1 shown, the present application provides a liquid outlet structure, which includes a transmission gear set 1, a pressure roller 2, a conduit 3 and a one-way bearing 4. The transmission gear set 1 has an input end gear 101 and an output end gear 102, wherein the input end gear 101 is used to receive external power input, and the output end gear 102 is used to drive the pressure roller 2 to rotate. The pressure roller 2 specifically includes a bracket and a plurality of rolling needles, and the rolling needles are evenly distributed at a certain interval around the axial direction of the bracket to ensure that the pressure roller 2 applies a uniform extrusion force to the conduit 3 during rotation. The pressure roller 2 and the output end gear 102 are coaxially arranged, so that the pressure roller 2 can rotate synchronously with the rotation of the output end gear 102, thereby realizing efficient power transmission. One end of the conduit 3 is a liquid inlet, and the other end is a liquid outlet. When the pressure roller 2 rotates, its outer surface periodically presses against the conduit 3, that is, each rolling needle presses against the conduit 3 in turn as the bracket rotates. Through the extrusion effect, the liquid in the conduit 3 generates a peristaltic effect, so as to convey the liquid from the liquid inlet to the liquid outlet direction and flow out from the liquid outlet. The one-way bearing 4 is arranged on the transmission path of the input end gear 101 and the output end gear 102 and is used to control the power transmission direction of the transmission gear set 1.

[0048] When the driving member 13 of the massage comb drives the input end gear 101 to rotate forward, the one-way bearing 4 enters the meshing state, transmits the power to the output end gear 102, and drives the pressure roller 2 to rotate synchronously. The needle rollers of the pressure roller 2 sequentially squeeze the pipe wall of the conduit 3 during rotation, generating a continuous peristaltic pump effect, forcing the liquid in the pipe to move directionally from the liquid inlet to the liquid outlet. At the same time, the driving member 13 synchronously drives the comb tooth assembly 14 to perform a massage action through the transmission mechanism, realizing the coordinated operation of massage and liquid discharge.

[0049] When the driving member 13 of the massage comb drives the input end gear 101 to rotate reversely, the one-way bearing 4 automatically disengages from the meshing state, interrupting the power transmission path, keeping the output end gear 102 and the pressure roller 2 in a stationary state. At this time, the liquid transportation process in the conduit 3 terminates, while the comb tooth assembly 14 still operates normally, thus realizing a single massage function.

[0050] The liquid discharge structure of the present application can still achieve at least two working modes and the switching between working modes without the need to be equipped with two power sources, which not only simplifies the driving structure of the massage comb but also improves the flexibility of function selection and the user experience.

[0051] As Figure 1 and Figure 2 shown, in a specific embodiment of the present application, the liquid discharge structure further includes a liquid distribution tray 5, which has liquid guiding holes 52 and liquid guiding grooves 51. Among them, the liquid guiding holes 52 are communicated with the liquid outlet of the conduit 3, and each liquid guiding groove 51 is uniformly arranged radially outward with the liquid guiding hole 52 as the center. This design of the radially distributed liquid guiding grooves 51 can ensure that the liquid flowing out of the liquid outlet can be evenly dispersed to each area of the liquid distribution tray 5, thereby improving the liquid distribution efficiency and use effect.

[0052] As Figure 1 and Figure 2 shown, in a specific embodiment of the present application, the liquid discharge structure further includes a liquid discharge housing 6, and the liquid distribution tray 5 is specifically arranged inside the liquid discharge housing 6. The liquid discharge housing 6 is provided with a plurality of liquid discharge convex columns 61, and the inlet ends of each liquid discharge convex column 61 are respectively communicated with the corresponding liquid guiding grooves 51 on the liquid distribution tray 5, thus forming a continuous channel for the liquid to flow from the liquid guiding grooves 51 to the liquid discharge convex columns 61. The outlet ends of the liquid discharge convex columns 61 are in contact with the scalp to apply the liquid to the scalp.

[0053] As Figure 1As shown, in a specific embodiment of the present application, the transmission gear set 1 further includes a first-stage reduction gear 103 and a second-stage reduction gear 104 to achieve multi-stage adjustment of the rotational speed. The input-end gear 101 is in meshing transmission connection with the first-stage reduction gear 103, thereby transmitting the power input by the driving member 13 from the input-end gear 101 to the first-stage reduction gear 103. The first-stage reduction gear 103 and the second-stage reduction gear 104 are coaxially arranged. The outer ring of the one-way bearing 4 is in transmission connection with one of the first-stage reduction gear 103 and the second-stage reduction gear 104, and the inner ring of the one-way bearing 4 is in transmission connection with the other of the first-stage reduction gear 103 and the second-stage reduction gear 104.

[0054] It should be noted that the transmission connection between the one-way bearing 4 and the first-stage reduction gear 103 and the second-stage reduction gear 104 includes, but is not limited to, direct contact connection, and also includes indirect connection achieved through a transmission shaft or other means. The specific setting form is as follows:

[0055] When both the outer ring and the inner ring of the one-way bearing 4 are straight cylindrical collars and the inner ring is arranged in the inner ring of the outer ring, the outer ring of the one-way bearing 4 can be directly connected to the first-stage reduction gear 103, and the inner ring of the one-way bearing 4 is connected to the transmission shaft. The torque is transmitted to the second-stage reduction gear 104 through the transmission shaft; when the first-stage reduction gear 103 rotates in the specified direction, the outer ring and the inner ring of the one-way bearing 4 are coupled, thereby driving the transmission shaft and the second-stage reduction gear 104 to rotate. When the rotation direction of the first-stage reduction gear 103 is opposite, the outer ring and the inner ring of the one-way bearing 4 slide, so that the torque cannot be transmitted to the transmission shaft and the second-stage reduction gear 104.

[0056] Alternatively, the transmission shaft is both connected to the first-stage reduction gear 103 and the inner ring of the one-way bearing 4; the outer ring of the one-way bearing 4 is connected to the second-stage reduction gear 104; when the first-stage reduction gear 103 and the transmission shaft rotate in the specified direction, the outer ring and the inner ring of the one-way bearing 4 are coupled, thereby driving the second-stage reduction gear 104 to rotate. When the rotation directions of the first-stage reduction gear 103 and the transmission shaft are opposite, the outer ring and the inner ring of the one-way bearing 4 slide, so that the torque cannot be transmitted to the second-stage reduction gear 104.

[0057] In addition, there is also a setting form of the one-way bearing 4, that is, the inner ring of the one-way bearing 4 includes a mating portion that mates with the outer ring, and the outer diameter of the meshing portion mates with the inner diameter of the outer ring; the inner ring of the one-way bearing 4 further includes an extension portion that extends axially out of the outer ring. The two gears are respectively connected to the outer ring of the one-way bearing 4 and the extension portion of the inner ring, so as to not only realize the staggered arrangement of the two gears, but also realize the one-way transmission between the two gears, and at the same time, the transmission can be realized without the need for external parts such as a transmission shaft.

[0058] The one-way bearing 4 is used to control the direction of power transmission. That is, when the first-stage reduction gear 103 rotates forward, the one-way bearing 4 is in the meshed state, driving the second-stage reduction gear 104 to rotate together; when the first-stage reduction gear 103 rotates reversely, the one-way bearing 4 automatically disengages from the meshed state, stopping the power transmission and causing the second-stage reduction gear 104 to stop rotating. The second-stage reduction gear 104 is connected to the output-end gear 102 through meshing transmission, thereby transmitting the power after two-stage reduction to the output-end gear 102. Through the two-stage reduction effect of two pairs of transmission gears, the transmission gear set 1 can gradually reduce the relatively high input speed at the driving member 13 to a speed range suitable for the operation of the pressure roller 2, not only effectively reducing the speed of the output-end gear 102, but also improving the torque output during the transmission process, thereby ensuring that the extrusion effect of the pressure roller 2 on the conduit 3 is more stable and reliable.

[0059] It should be noted that the forward rotation direction of the first-stage reduction gear 103 refers to the rotation direction that can transmit torque through the one-way bearing 4, and the reverse rotation direction of the first-stage reduction gear 103 refers to the rotation direction that cannot transmit torque through the one-way bearing 4. The forward / reverse rotation direction of the first-stage reduction gear 103 does not refer to the clockwise or counterclockwise rotation working direction controlled by the power driving component.

[0060] As Figure 1 shown, in a specific embodiment of the present application, the liquid outlet structure further includes an upper cover 7, a middle cover 8, and a lower cover 9 that are connected in sequence. The three are fixedly connected by fasteners to form a complete housing structure. The upper cover 7 and the middle cover 8 enclose a first accommodation cavity for accommodating the input-end gear 101 and the first-stage reduction gear 103. The upper cover 7, the middle cover 8, and the lower cover 9 also enclose a second accommodation cavity for accommodating the second-stage reduction gear 104, the output-end gear 102, the pressure roller 2, and at least a part of the flexible conduit 3. This cavity-dividing structure can not only achieve a reasonable layout of each component, but also effectively isolate different functional areas, avoiding mutual interference between components, thereby improving the stability of the structure and the reliability of operation.

[0061] The liquid distribution disk 5 and the lower cover 9 enclose a liquid outlet cavity, and the liquid outlet end of the conduit 3 is communicated with the liquid outlet cavity, so that the liquid can be transported through the conduit 3 into the liquid outlet cavity and evenly distributed and output through the liquid guide grooves 51 and the liquid outlet convex columns 61 on the liquid distribution disk 5.

[0062] As Figure 1 shown, in a specific embodiment of the present application, the liquid outlet structure further includes a liquid storage member 10 connected to the upper cover 7. The liquid storage member 10 has a liquid supply port, an openable and closable liquid replenishment port, and a liquid storage cavity. Among them, the liquid supply port is communicated with the liquid inlet port of the conduit 3. The liquid replenishment port can be equipped with a sealing rubber plug or a screw cap, etc., to achieve sealed storage and convenient replenishment of the liquid.

[0063] In use, the user injects a required amount of nursing solution into the liquid storage cavity through the liquid replenishing port. When the driving member 13 of the massage comb is activated, the liquid in the liquid storage cavity naturally flows into the conduit 3 through the liquid supply port under the action of gravity, and then forms a directional flow under the periodic squeezing action of the pressure roller 2.

[0064] As Figure 2 and Figure 3 shown, the present application also provides a massage comb, which includes a housing 11, a transmission member 12, a driving member 13, a comb tooth assembly 14, and the liquid outlet structure in the above embodiment.

[0065] The housing 11 serves as the main frame of the massage comb and is used to accommodate and support each functional component. The transmission member 12 is rotatably connected to the housing 11 and has a first engagement portion 121, a second engagement portion 122, and an orbital groove 123. The first engagement portion 121 is used to connect with the driving member 13, the second engagement portion 122 is used to connect with the input gear 101 of the liquid outlet structure, and the orbital groove 123 is used to guide the movement of the comb tooth assembly 14. The driving member 13 (such as a motor) is fixedly installed on the housing 11, and its output end is drivingly connected to the first engagement portion 121 of the transmission member 12, and drives the transmission member 12 to rotate by forward or reverse rotation.

[0066] The comb tooth assembly 14 includes a comb tooth base 141 and a comb tooth group 142. The comb tooth base 141 is fixedly connected to the housing 11, and an opening is provided thereon for the liquid outlet structure to pass through the comb tooth base 141. The comb tooth group 142 is movably connected to the comb tooth base 141. One end of the comb tooth group 142 extends into the orbital groove 123 of the transmission member 12 and is slidably connected to the orbital groove 123, and the other end extends toward the outside of the comb tooth base 141. When the transmission member 12 rotates, the other end of the comb tooth group 142 swings alternately in a direction approaching or departing from the axis of the opening, thereby realizing the massage function. The comb tooth group 142 includes an integrally formed connecting base and a plurality of spaced-apart comb teeth, and the connecting base is movably connected to the comb tooth base 141.

[0067] In the above embodiments, the input gear 101 of the liquid outlet structure is drivingly connected to the second engagement portion 122 of the transmission member 12 to achieve unidirectional liquid delivery. When the driving member 13 of the massage comb drives the input gear 101 to rotate forward, the one-way bearing 4 enters the engaged state, transmits the power to the output gear 102, and drives the pressure roller 2 to rotate synchronously. The rolling pins of the pressure roller 2 sequentially squeeze the pipe wall of the conduit 3 during rotation, generating a continuous peristaltic pump effect, forcing the liquid in the pipe to move directionally from the liquid inlet to the liquid outlet. At the same time, the driving member 13 synchronously drives the comb tooth assembly 14 to perform a massage action through the transmission mechanism, realizing the coordinated operation of massage and liquid outlet. When the driving member 13 of the massage comb drives the input gear 101 to rotate reversely, the one-way bearing 4 automatically disengages from the engaged state, interrupting the power transmission path, keeping the output gear 102 and the pressure roller 2 stationary. At this time, the liquid delivery process in the conduit 3 terminates, while the comb tooth assembly 14 still operates normally, thus realizing a single massage function.

[0068] Without the need to be equipped with two power sources, the massage comb of the present application can still achieve at least two working modes and the switching between the working modes, which not only simplifies the driving structure of the massage comb, but also improves the flexibility of function selection and enhances the user experience.

[0069] As Figure 2 and Figure 3 shown, in a specific embodiment of the present application, the transmission member 12 is specifically an annular transmission disk, and its structure includes an outer ring surface, an inner ring surface, and an end surface. The first engagement portion 121 is arranged on the outer ring surface of the annular transmission disk, specifically an external engagement gear ring, for meshing and connecting with the output end of the driving member 13. The second engagement portion 122 is arranged on the inner ring surface of the annular transmission disk, specifically an internal engagement gear ring, for meshing and connecting with the input gear 101 of the liquid outlet structure to drive the operation of the liquid outlet structure. The track groove 123 is arranged on the end surface of the annular transmission disk, and its track shape is specifically wavy. This wavy track can guide one end of the comb tooth group 142 to slide in the track groove 123, so that the other end of the comb tooth group 142 can swing alternately in a direction approaching or departing from the axis of the opening. The distribution of the wave crests and wave troughs of the wavy track is reasonably optimized to ensure that the swing amplitude and frequency of the comb tooth group 142 can meet the requirements of the massage function.

[0070] As Figure 2 and Figure 3 shown, in another specific embodiment of the present application, the number of the comb tooth groups 142 is multiple, and each comb tooth group 142 is evenly spaced along the circumference of the opening of the comb tooth seat 141. This arrangement can ensure that the comb tooth groups 142 cover a larger scalp area when swinging, thereby improving the massage effect and using comfort.

[0071] As Figure 2 and Figure 3As shown, in a specific embodiment of the present application, the massage comb further includes a light-emitting member 15 and a light-transmitting cover 16. The light-transmitting cover 16 is disposed on the liquid outlet housing 6, and the light-emitting member 15 is adhesively bonded to the liquid outlet housing 6 with a back adhesive and is located between the light-transmitting cover 16 and the liquid outlet housing 6.
