Description

Technical Field

[0001] The present invention relates to the technical field of massagers, and particularly to a liquid discharging structure and a massage comb. Background Art

[0002] Hair combing is an integral part of grooming, and a comb as an auxiliary tool makes it more convenient for users to comb their hair. Traditional combs only have the function of ordinary hair combing and cannot meet the needs of users to apply care solutions to their hair or scalp for hair care. Along with the large market demand, many merchants have launched massage combs. During the process of combing hair, users can control the massage comb to push the care solution inside it out through its self - contained liquid discharging structure and apply it to the user's hair or scalp.

[0003] For the liquid discharging structure of common massage combs, one type is that a spring is arranged inside the liquid discharging comb teeth, a ball is arranged at the end of the liquid discharging comb teeth, the upper end of the spring abuts against other components, and the lower end of the spring abuts against the ball. When the ball is squeezed, the spring is forced to retract, and the ball retracts into the liquid discharging comb teeth. At this time, the care solution flows out along the end of the liquid discharging comb teeth. Its disadvantages are that, on the one hand, the care solution cannot be effectively controlled, and it is difficult to discharge liquid quantitatively. Different squeezing forces and angles may lead to uneven liquid discharge. On the other hand, for viscous care solutions or after long - term use of the massage comb, the ball is easily blocked at the liquid outlet, affecting the user experience; another type is to use a peristaltic pump as the power. One end of the pump tube is communicated with the liquid storage bin, and the other end of the pump tube is communicated with the liquid discharging comb teeth. The peristaltic pump works to suck the liquid and discharge it from the liquid discharging comb teeth. Its disadvantages are that the peristaltic pump conveys the care solution by periodically squeezing the pump tube, resulting in unstable liquid discharge and difficult to achieve uniform liquid discharge. In addition, when the massage comb is used obliquely, the liquid storage bin of the liquid discharging structure will be tilted, and the suction port of the pump tube may not be able to contact the care solution, thus affecting the normal operation of the liquid discharging structure.

[0004] Therefore, the prior art still needs to be improved and enhanced. Summary of the Invention

[0005] In view of the above - mentioned deficiencies of the prior art, the purpose of the present invention is to provide a liquid discharging structure and a massage comb, aiming to solve at least one problem of the poor use effect of the liquid discharging structure in the background art.

[0010] A power member, the power member drives the moving assembly to act, and the moving assembly adjusts the relative volumes of the first chamber and the second chamber, so that the liquid in the first chamber is discharged from the liquid outlet comb teeth.

[0011] The liquid outlet structure further includes an upper cover arranged at the other end of the housing. The power member is located inside the upper cover. The power member outputs a medium to the second chamber, and the moving assembly squeezes the first chamber, so that the liquid in the first chamber is discharged from the liquid outlet comb teeth.

[0013] The moving assembly further includes a moving member and an elastic member. The triggering unit is axially movably arranged on the moving member. The moving member and the triggering unit define a channel communicating the first chamber and the second chamber. The housing is sleeved on the outer periphery of the moving member. The elastic member is sleeved on the triggering unit and is located between the triggering end of the triggering unit and the moving member. When the triggering unit is pressed, the elastic member is compressed and the triggering unit acts, and the channel is opened. When the elastic member resets, the channel is closed.

[0014] An installation portion is axially arranged in the middle of the moving member, and a supporting portion is arranged on the inner wall of the installation portion to limit the triggering unit on the moving member. The channel includes a guiding port located on the supporting portion.

[0017] A guiding portion adapted to the communication port is arranged on the pressing member.

[0018] A diversion component is arranged inside the bottom cover. One end of the diversion component communicates with the first chamber, and the other end of the diversion component communicates with the roots of the liquid outlet comb teeth.

[0019] The diversion component includes a diversion plate and a flow splitting unit. The flow splitting unit is arranged on the bottom cover. The diversion plate is installed inside the bottom cover and is located above the flow splitting unit. The diversion plate is provided with diversion holes to guide the liquid in the first chamber to enter the liquid outlet comb teeth through the flow splitting unit and be discharged.

Detailed implementation manners

[0035] To make the objectives, technical solutions and effects of the present invention clearer and more definite, the following further elaborates the present invention with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] It should be noted that when a component is referred to as being "mounted on", "fixed to" or "disposed on" another component, it can be directly on the other component or there may be an intermediate component at the same time. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or there may be an intermediate component at the same time.

[0037] It should also be noted that the terms of orientation such as left, right, up, and down in the embodiments of the present invention are only relative concepts to each other or are referenced based on the normal use state of the product, and should not be considered restrictive.

[0038] Hair combing is an integral part of grooming, and a comb, as an auxiliary tool, makes it more convenient for users to comb their hair. Traditional combs only have the function of ordinary hair combing and cannot meet the needs of users to apply hair care liquid to their hair or scalp for hair care. Along with the large market demand, many merchants have launched massage combs. During the process of combing hair, users can control the massage comb to push the hair care liquid inside it to flow out through the built-in liquid outlet structure and apply it to the user's hair or scalp.

[0039] For the liquid outlet structure of common massage combs, one is to set a spring inside the liquid outlet comb teeth, with a ball at the end of the liquid outlet comb teeth. The upper end of the spring abuts against other components, and the lower end of the spring abuts against the ball. When the ball is squeezed, the spring is forced to retract, and the ball retracts into the liquid outlet comb teeth. At this time, the hair care liquid flows out along the end of the liquid outlet comb teeth. Its disadvantages are that, on the one hand, the hair care liquid cannot be effectively controlled, and it is difficult to quantitatively discharge the liquid. Different squeezing forces and angles may lead to uneven liquid discharge. On the other hand, for viscous hair care liquid or after long-term use of the massage comb, the ball is prone to block the liquid outlet, affecting the user experience; the other is to use a peristaltic pump as the power. One end of the pump tube is connected to the liquid storage chamber, and the other end of the pump tube is connected to the liquid outlet comb teeth. The peristaltic pump works to suck the liquid in the pump tube and discharge it from the liquid outlet comb teeth. Its disadvantages are that the peristaltic pump transports the hair care liquid by periodically squeezing the pump tube, resulting in unstable liquid discharge and difficulty in achieving uniform liquid discharge. In addition, when the massage comb is used obliquely, the liquid storage chamber of the liquid outlet structure will be tilted, and the suction port of the pump tube may not be able to contact the hair care liquid, thus affecting the normal operation of the liquid outlet structure.

[0040] Based on the deficiencies of the existing technology, the present invention provides a liquid outlet structure. Please refer to Figures 1-9 , including:

[0041] A housing 1, having an accommodation cavity, and a moving component 11 is arranged inside the housing 1 to divide the accommodation cavity into a first chamber and a second chamber;

[0042] A bottom cover 2, the bottom cover 2 is arranged at one end of the housing 1, and a plurality of liquid outlet comb teeth 21 are arranged on the bottom cover 2;

[0043] Power component 31, the power component 31 drives the movement of the moving component 11, and the moving component 11 adjusts the relative volume of the first chamber and the second chamber, so that the liquid in the first chamber is discharged from the liquid outlet comb teeth 21. In the liquid outlet structure 10 of the present application, the liquid is located in the first chamber. By driving the moving component 11 to act through the power component 31 and adjusting the relative volume of the first chamber and the second chamber, the liquid in the first chamber is pushed out from the liquid outlet comb teeth 21, and the liquid outlet volume can be controlled more precisely. At the same time, the moving component 11 pushes the liquid to be discharged from a plurality of liquid outlet comb teeth 21, so that the liquid is more uniform when discharged from different liquid outlet comb teeth 21, improving the quality and stability of the liquid discharge.

[0044] In the present application, the power component 31 drives the moving component 5 to act, that is, the power component 31 needs to drive the moving component 11 to move axially along the inner wall of the housing 1 to push the liquid in the first chamber out. During this process, the moving path of the moving component 11 is a straight line. Based on this moving path, the power component 31 can select a hydraulic drive mechanism, a pneumatic drive mechanism, a linear motor mechanism, a combination mechanism of a motor and a linear transmission unit, etc. It should be noted that the power component 31 in the present application does not only refer to power units such as motors, air pumps, and hydraulic pumps, but refers to a mechanism that can drive the moving component 11 to move axially in the housing 1.

[0045] In the embodiment of the present application, the moving component 11 is sleeved on the inner side of the housing 1, and the moving component 11 can move axially along the inner wall of the housing 1. When the power component 11 drives the moving component 11 to act, the moving component 11 squeezes the liquid in the first chamber. In order to prevent the liquid in the first chamber from seeping into the second chamber through the gap between the moving component 11 and the housing 1 and to improve the smoothness of the movement of the moving component 11, at least one first sealing ring 12 is sleeved on the periphery of the moving component 11. In the embodiment of the present application, three first sealing rings 12 are sleeved on the periphery of the moving component 11. Of course, other numbers of sealing rings can also be set, which are foreseeable adjustments and are not limited in the present application. Alternatively, when the moving component 11 is sleeved on the inner side of the housing 1 in the present application, the periphery of the moving component 11 can also be in direct contact with the inner wall of the housing 1. The outer periphery of the moving component 11 can adopt rubber or other flexible materials to contact the inner wall of the housing 1, so as to avoid gaps between the moving component 11 and the housing 1.

[0046] Further, in the embodiment of the present application, an external thread is provided on the peripheral side of the bottom cover 2, and an internal thread is provided on the inner wall of the first chamber of the housing 1. The bottom cover 2 is installed at the lower end of the housing 1 by means of rotational fit. At this time, the moving assembly 11 and the bottom cover 2 respectively limit the liquid within the housing 1 from both ends of the first chamber; the bottom cover 2 is connected to the housing 1 by means of threaded rotational fit, with a simple structure and convenient disassembly and assembly. Alternatively, the bottom cover 2 can also be installed at the lower end of the housing 1 by means of plug-in fit. Specifically, the upper end portion of the bottom cover 2 is inserted into the housing 1 and the peripheral side of the inserted portion is closely attached to the inner wall of the housing 1. A step is provided on the peripheral side of the bottom cover 2 to define the depth of the plug-in fit between the two. In order to prevent the liquid in the first chamber from leaking out from the connection between the bottom cover 2 and the housing 1, a ring-shaped step is provided at the end of the housing 1 for installing the second sealing ring 22; when the bottom cover 2 is rotatably installed with the housing 1, the second sealing ring 22 will be squeezed, improving the sealing performance at the connection between the bottom cover 2 and the housing 1 and preventing the liquid from leaking out from the connection.

[0047] Further, the liquid outlet structure 10 further includes an upper cover 3 provided at the other end of the housing 1. The power member 31 is located within the upper cover 3. The power member 31 outputs a medium to the second chamber, and the moving assembly 11 squeezes the first chamber so that the liquid in the first chamber is discharged from the liquid outlet comb teeth 21. In the present application, the bottom cover 2 is located at the lower end of the housing 1, and the upper cover 3 is located at the upper end of the housing 1. The vertical position relationships of other components in the present application are all referenced based on this. In addition, moving along the axial direction refers to moving in the up and down direction with reference to the positions of the bottom cover 2 and the upper cover 3.

[0048] In this application, a one-way valve 32 is provided on the upper cover 3. The medium output by the power component 31 is gas. After the gas output by the power component 31 enters the second chamber through the one-way valve 32, the continuous gas input will drive the moving component 11 to move, so as to squeeze the liquid in the first chamber and make the liquid discharged through the liquid outlet comb teeth 21. The advantage of using pneumatic drive to push the moving part 5 to act is that by adjusting the pressure and flow rate of the pneumatic system, the movement speed and formation of the cylinder can be accurately controlled, and then the position change of the moving component 11 in the liquid outlet structure 10 can be accurately controlled, so as to accurately adjust the relative volume of the first chamber and the second chamber, and thus accurately control the liquid output; the pneumatic mechanism can provide a relatively stable linear motion, so that the moving component 11 acts evenly when adjusting the chamber volume, avoiding the situation of uneven liquid output caused by unstable movement, ensuring that the liquid discharged from the liquid outlet comb teeth 21 is uniform and stable, and improving the user experience when using the massage comb; the pneumatic mechanism has the characteristics of fast response. When liquid output is required, it can quickly drive the moving component 11 to act to achieve rapid liquid output; when liquid output is not required, it can quickly stop, meeting the user's demand for instant control of liquid output, especially suitable for the situation where the user frequently starts and stops liquid output according to needs; the pneumatic mechanism structure is relatively simple and compact, easy to install in the limited space of the liquid outlet structure 10, without increasing too much volume and weight, which is beneficial to maintaining the overall lightness of the massage comb; the pneumatic mechanism has less wear on components and has a long service life, which can ensure that the liquid outlet structure 10 of the massage comb works stably and reliably during long-term use, reducing the maintenance and replacement costs caused by mechanism failures and improving the user experience. For the hydraulic mechanism, it needs to transmit power through hydraulic medium, there is a risk of leakage, increasing the weight of the liquid outlet structure 10, and the overall structure is also relatively complex, with poor response speed; for the motor mechanism, the overall structure is relatively complex, and it occupies a large space, and the motor is prone to generate noise during operation.

[0049] Further, the moving component 11 includes a trigger unit 4. The trigger end of the trigger unit 4 faces the first chamber side. When the trigger unit 4 is triggered, the second chamber communicates with the first chamber, and the moving component 11 moves toward the second chamber side to adjust the relative volume of the first chamber and the second chamber.

[0050] In the foregoing embodiment, the pneumatic mechanism is used to drive the movement of the moving component 11. After the liquid in the first chamber is completely drained through the liquid outlet comb teeth 21 by the moving component 11, the volume of the second chamber is the largest relative to that of the first chamber at this time, and the second chamber is filled with gas. In order to reuse the liquid outlet structure 10, that is, to discharge the gas in the second chamber and replenish the liquid in the first chamber, it is necessary to drive the moving component 11 to move toward the second chamber side so that there is enough volume in the first chamber to accommodate the liquid. At this time, the relative rotating bottom cover 2 and the housing 1 are disassembled, the trigger end of the trigger unit 4 is pressed to communicate the first chamber and the second chamber. At the same time, the moving component 11 moves toward the second chamber side, and the gas in the second chamber can be discharged to the outside through the opening of the first chamber and the housing 1. The trigger unit 4 is equivalent to a pressure relief device, that is, pressing the trigger unit 4 can discharge the pressure generated by the gas in the second chamber through the first chamber and the housing 1 to ensure that the moving component 11 can move smoothly toward the second chamber. When the trigger end of the trigger unit 4 is not pressed, the moving component 11 separates the first chamber and the second chamber, and the two chambers are not connected.

[0051] Further, the moving component 11 further includes a moving member 5 and an elastic member 6. The trigger unit 4 is axially movably disposed on the moving member 5. The moving member 5 and the trigger unit 4 define a channel communicating the first chamber and the second chamber. The housing 1 is sleeved on the outer periphery of the moving member 5. The elastic member 6 is sleeved on the trigger unit 4 and is located between the trigger end of the trigger unit 4 and the moving member 5. When the trigger unit 4 is pressed, the elastic member 6 is compressed and the trigger unit 4 is actuated, and the channel is opened. When the elastic member 6 is reset, the channel is closed.

[0052] In the embodiment of the present application, a groove is provided on the outer periphery of the moving member 5 for installing the first sealing ring 12. The first sealing ring 12 contacts the inner wall of the housing 1. Under the extrusion of the moving member 5 and the housing 1, the first sealing ring 12 deforms to separate the first chamber and the second chamber, thereby preventing the liquid in the first chamber from seeping into the second chamber when the triggering unit 4 is not pressed. The triggering unit 4 is generally in an I-shaped structure. The upper end of the triggering unit 4 is used to open or close the channel connecting the first chamber and the second chamber. The lower end of the triggering unit 4 is for the user to press, so as to drive the triggering unit 4 to move axially on the moving member 5; the elastic member 6 is sleeved on the triggering unit 4 axially, and the upper end of the elastic member 6 abuts against the moving member 5, and the lower end of the elastic member 6 abuts against the upper end of the triggering unit 4. When the user presses the lower end of the triggering unit 4, the triggering unit 4 compresses the elastic member 6, and the triggering unit 4 moves axially under the guidance of the moving member 5. During this movement process, the upper end of the triggering unit 4 moves upward to open the channel, so that the first chamber and the second chamber are communicated; after the user releases the triggering unit 4, under the elastic force of the elastic member 6, the triggering unit 4 returns to its initial state to close the channel connecting the first chamber and the second chamber. At this time, the first chamber and the second chamber are relatively independent under the separation of the moving assembly 11, that is, gas cannot flow between the two. The setting of the elastic member 6 enables the triggering unit 4 to automatically return to its position after the user releases the triggering unit 4, and the upper end of the triggering unit 4 closes the channel connecting the first chamber and the second chamber, with a delicate structure, simple control and low cost.

[0053] Further, an installation portion 51 is axially provided in the middle of the moving member 5, and a supporting portion 52 is provided on the inner wall of the installation portion 51 to limit the triggering unit 4 on the moving member 5; the channel includes a guiding port 521 located on the supporting portion 52.

[0054] In the embodiment of the present application, a cylindrical structure with both ends open, that is, the installation portion 51, is axially provided in the middle of the moving member 5 for accommodating a part of the triggering unit 4 to extend into and for installing the triggering unit 4; the supporting portion 52 is approximately in a ring shape and is formed by extending from the inner wall of the installation portion 51 towards the middle. The supporting portion 52 divides the space in the installation portion 51 into upper and lower parts. The upper end of the elastic member 6 extends into the lower space of the installation portion 51, and the upper end of the elastic member 6 abuts against the lower end surface of the supporting portion 52. The lower end of the elastic member 6 is located outside the lower space of the installation portion 51 and abuts against the lower end of the triggering unit 4. The upper space of the installation portion 51 is used to accommodate the upper part of the triggering unit 4, and guides the axial movement of the triggering unit 4 when pressing the lower end of the triggering unit 4 to ensure the stability of the movement of the triggering unit 4.

[0055] Further, the triggering unit 4 includes a trigger member 41, a pressing member 42, and a sealing member 43. The fixed end of the trigger member 41 passes through the through hole of the supporting portion 52 and is fixedly connected to the pressing member 42. The sealing member 43 is sleeved on the pressing member 42, and the sealing member 43 contacts the inner wall of the mounting portion 51.

[0056] In the embodiment of the present application, the trigger member 41 is generally in a T-shaped structure and is disposed in an inverted manner on the moving member 5. The fixed end (i.e., the vertical portion) of the trigger member 41 extends into the upper space of the mounting portion 51 through the through hole of the annular supporting portion 52 and is screwed and fixed to the pressing member 42. Under the action of the elastic member 6, the annular supporting portion 52 abuts against the pressing member 42 to dynamically limit the triggering unit 4 on the moving member 5. A limiting portion 44 is provided at the lower end of the trigger member 41. When the lower end of the trigger member 41 is pressed, the limiting portion 44 will abut against the lower end of the moving member 5. On the one hand, it is to protect the elastic member 6 and prevent the elastic member 6 from being over-compressed, which affects the service life of the elastic member 6. On the other hand, it limits the axial movement distance of the triggering unit 4 when opening the channel, which is beneficial to improving the efficiency of opening and closing the channel. Further, an abutting portion 411 extends from the circumferential side of the limiting portion 44 toward the moving member 5. An abutting groove 53 adapted to the abutting portion 411 is provided on the lower end surface of the moving member 5 to prevent the trigger member 41 from swinging left and right when pressed in place, thereby improving the user experience; both the abutting portion 411 and the abutting groove 53 are annular.

[0057] In an embodiment of the present application, since the sealing member 43 sleeved on the outer periphery of the pressing member 42 contacts the inner wall of the mounting portion 51 to close the channel when the trigger member 41 is not pressed, in order to open the channel, it is necessary to press the trigger member 41 to make the pressing member 42 and the sealing member 43 move axially. When the circumferential side of the sealing member 43 does not contact the inner wall of the mounting portion 51, the channel is opened at this time. Specifically, by pressing the trigger member 41, the position of the sealing member 43 can be higher than the upper end surface height of the mounting portion 51. At this time, the gas in the second chamber can enter the first chamber through the guiding port 521 and be discharged to the outside.

[0058] In addition, to ensure that when the position of the seal 43 is higher than the upper end face of the mounting portion 51, the peripheral side of the pressing member 42 contacts the inner wall of the mounting portion 51, or the gap between the peripheral side of the pressing member 42 and the inner wall of the mounting portion 51 is too small, affecting the gas passing efficiency, a chamfered surface 421 can be provided on the peripheral side of the lower end portion of the pressing member 42. When the chamfered surface 421 approaches the upper end face of the mounting portion 51, the chamfered surface 421 creates a relatively large gap between the peripheral side of the pressing member 42 and the end portion of the mounting portion 51, making the gas flow more smoothly from the second chamber into the first chamber through the guiding port 521. In addition, if the pressing member 42 is pushed to a position higher than the upper end face of the mounting portion 51, the chamfered surface 421 also plays a guiding role during the reset process of the pressing member 42, facilitating the pressing member 42 to re-enter the mounting portion 51 and ensuring the smooth reset of the pressing member 42.

[0059] Further, a communication port 54 is provided on the mounting portion 51; when the trigger member 41 of the trigger unit 4 is pressed, the elastic member 6 is compressed and the trigger unit 4 is actuated, and the communication port 54 communicates the second chamber with the first chamber through the guiding port 521.

[0060] Based on the fact that the chamfered surface 421 is provided on the peripheral side of the lower end portion of the pressing member 42 in the foregoing embodiment, in another embodiment of the present application, a guiding curved surface 55 adapted to the chamfered surface 421 can be provided on the inner wall of the upper opening of the mounting portion 51, and the guiding curved surface 55 is provided along the inner wall of the mounting portion 51. The guiding curved surface 55 is in a circular opening shape and the opening gradually becomes larger from bottom to top; further, a communication port 54 is provided on the upper peripheral side wall of the mounting portion 51. When the seal 43 on the pressing member 42 moves axially to the height where the guiding curved surface 55 is located, the guiding curved surface 55 causes a gap between the seal 43 and the inner wall of the mounting portion 51 at the height of the guiding curved surface 55. At this time, the gas in the second chamber can first enter the first chamber through the communication port 54 and then through the guiding port 521; the chamfered surface 421 and the guiding curved surface 55 make the gas flow more smoothly from the second chamber into the first chamber through the guiding port 521, and at the same time, the cooperation between the two also plays a guiding role during the reset process of the pressing member 42; in this embodiment, it is not necessary to push the position of the seal 43 higher than the upper end face of the mounting portion 51, and only making the seal 43 located at the height where the guiding curved surface 55 is located is beneficial to improving the working efficiency of the trigger unit 4 and minimizing the faults during the operation of the trigger unit 4 as much as possible.

[0061] Further, a guiding portion 422 adapted to the communication port 54 is provided on the pressing member 42. In the embodiment of the present application, the guiding portion 422 is provided on the circumferential side of the chamfered surface 421. The guiding portion 422 is a concave surface provided on the chamfered surface 421. Its purpose is to further improve the gas flow efficiency when the second chamber and the first chamber are communicated, so that the gas in the second chamber quickly enters the first chamber through the guiding port 521 and is discharged to the outside, realizing rapid pressure relief. It should be noted that when the gas in the second chamber of the present application enters the first chamber through the guiding port 521 and is discharged to the outside, the lower end of the housing 1 is not assembled with the bottom cover 2, that is, the bottom cover 2 needs to be rotated and removed from the housing 1 first, and the gas entering the first chamber needs to be discharged to the outside through the opening at the lower end of the housing 1.

[0062] Further, a flow guiding assembly 7 is provided in the bottom cover 2. One end of the flow guiding assembly 7 communicates with the first chamber, and the other end of the flow guiding assembly 7 communicates with the tooth roots of the liquid outlet comb teeth 21; the flow guiding assembly 7 includes a flow guiding plate 71 and a flow dividing unit 72. The flow dividing unit 72 is provided on the bottom cover 2. The flow guiding plate 71 is installed in the bottom cover 2 and is located above the flow dividing unit 72. Flow guiding holes 711 are provided on the flow guiding plate 71 to guide the liquid in the first chamber to enter the tooth roots of the liquid outlet comb teeth 21 through the flow dividing unit; the flow dividing unit 72 includes a flow dividing portion 721, a converging portion 722 and a flow channel 23. The converging portion 722 is circumferentially arranged around the flow dividing portion 721. The flow dividing portion 721 and the center of the flow guiding hole 711 are arranged along the same axis. The converging portion 722 and the flow dividing portion 721 define a space communicating with one end of the flow channel 23, and the other end of the flow channel 23 communicates with the tooth roots of the liquid outlet comb teeth 21.

[0063] Further, a sealing gasket 8 is provided below the flow guiding plate 71. A step is provided on the lower end surface of the flow guiding plate 71. When the sealing gasket 8 and the flow guiding plate 71 are installed on the bottom cover 2, the upper end of the flow dividing unit 72 extends into the step through the round hole in the center of the sealing gasket 8 to prevent the liquid from seeping out around between the flow guiding plate 71 and the bottom cover 2; when the sealing gasket 8 is installed on the bottom cover 2, the sealing gasket 8 covers the upper end of the flow channel 23 and cooperates with the flow channel 23 to guide the liquid.

[0064] In the embodiment of the present application, the diversion hole 711 is located in the middle of the diversion plate 71. An arc-shaped curved surface in a funnel shape is provided at the opening of the diversion hole 711 to better guide the liquid to enter. The diversion part 721 is approximately in the shape of a triangular pyramid, and the diversion part 721 is located directly below the diversion hole 711. After the liquid passes through the diversion hole 711, under the diversion effect of the diversion part 721, it flows to three flow channels 23 respectively, and then flows along the set direction of the flow channels 23 to the root of the teeth of the liquid outlet comb teeth 21 until it flows out from the end of the liquid outlet comb teeth 21. In order to ensure that the liquid can enter the flow channels 23 evenly and smoothly after being diverted by the diversion part 721, a confluence part 722 is arranged around the diversion part 721. The confluence part 722 cooperates with the diversion part to define a space, which plays a role in converging and guiding the liquid, so that the liquid can smoothly enter one end of the flow channels 23. The setting of the diversion unit 72 makes the amount of liquid entering the three liquid outlet comb teeth 21 as the same as possible, thereby ensuring that the three liquid outlet comb teeth 21 discharge liquid evenly and improving the user experience.

[0065] The present invention also provides a massage comb. Please refer to Figures 1-11 , including a massage comb main body 20 and the liquid outlet structure 10 arranged on the massage comb main body 20.

[0066] In the embodiment of the present application, an installation cavity 200 is arranged on the massage comb main body 20 for installing the liquid outlet structure 10. Both ends of the installation cavity 200 are open. The lower end of the liquid outlet structure 10, that is, the end where the liquid outlet comb teeth 21 are located, extends into the installation cavity 200 from the back of the massage comb main body 20, and then the two are rotated relative to each other to achieve buckling and fixation. Specifically, a buckling part 102 is arranged on the shell 1 of the liquid outlet structure 10, a step part 201 is arranged in the installation cavity 200, an installation groove 202 adapted to the buckling part 102 is arranged on the circumferential side of the step part 201. The installation groove 202 is in an L shape, and the open end of the installation groove 202 faces the side of the liquid outlet structure 10 for the buckling part 102 to be placed in the installation groove 202. After the liquid outlet structure 10 and the massage main body are rotated relative to each other, the buckling part 102 will abut against the closed end of the installation groove 202, and the assembly of the liquid outlet structure 10 and the massage comb main body 20 can be realized. Further, a probe 203 is arranged on the end face of the step part 201, and a trigger part 101 adapted to the probe 203 is arranged on the shell 1.
