Description

Technical Field

[0001] This utility model relates to the field of massager technology, and in particular to a liquid dispensing structure and a massage comb. Background Technology

[0002] Hair combing is an integral part of grooming, and combs, as auxiliary tools, make hair combing more convenient. Traditional combs only have the function of ordinary hair combing and cannot meet the needs of users to apply conditioning lotion to their hair or scalp to care for their hair quality. With the large market demand, many manufacturers have launched massage combs. During the hair combing process, users can control the massage comb to push out the conditioning lotion inside through its built-in liquid dispensing mechanism and apply it to their hair or scalp.

[0003] One common liquid dispensing mechanism in massage combs involves a spring inside the comb teeth, with a ball bearing at the end of each tooth. The upper end of the spring abuts against other components, while the lower end abuts against the ball bearing. When the ball bearing is compressed, the spring retracts, causing the ball bearing to retract into the comb teeth, allowing the liquid to flow out. However, this method has drawbacks. Firstly, it's difficult to effectively control the liquid dispensing, making it hard to dispense a precise amount. Different compression forces and angles can lead to uneven dispensing. Secondly, it can be problematic with viscous liquids or after prolonged use of the massage comb. Ball bearings can easily clog the liquid outlet, affecting the user experience. Another method uses a peristaltic pump as the power source. One end of the pump tube is connected to the liquid storage tank, and the other end is connected to the liquid dispensing comb teeth. The peristaltic pump works by drawing liquid from the pump tube and dispensing it from the liquid dispensing comb teeth. However, the peristaltic pump delivers the care solution by periodically squeezing the pump tube, resulting in uneven liquid dispensing and difficulty in achieving uniform dispensing. In addition, when the massage comb is used at an angle, it will cause the liquid storage tank of the liquid dispensing structure to tilt, and the pump tube suction port may not be able to contact the care solution, thus affecting the normal operation of the liquid dispensing structure.

[0004] Therefore, existing technologies still need to be improved and enhanced. Utility Model Content

[0010] A power component drives the moving assembly to adjust the relative volume of the first chamber and the second chamber so that liquid in the first chamber is discharged from the liquid outlet comb.

[0011] The liquid outlet structure also includes an upper cover disposed at the other end of the housing, the power unit is located inside the upper cover, the power unit outputs the medium to the second chamber, and the moving component squeezes the first chamber so that the liquid in the first chamber is discharged from the liquid outlet comb.

[0012] The moving component includes a triggering unit, the triggering end of which faces the first chamber.

The sealing element is sleeved on the pressing element and contacts the inner wall of the mounting portion.

[0016] The mounting part is provided with a communication port; pressing the trigger element of the trigger unit, compressing the elastic element and causing the trigger unit to move, the communication port connects the second chamber and the first chamber through the guide port.

[0017] The pressing component is provided with a guide portion that is adapted to the communication port.

[0018] A flow guiding component is provided inside the bottom cover. One end of the flow guiding component is connected to the first chamber, and the other end of the flow guiding component is connected to the root of the liquid outlet comb teeth.

In the liquid dispensing structure of this application, the liquid is located in the first chamber. By driving the moving component to adjust the relative volume of the first chamber and the second chamber, the liquid in the first chamber is pushed out from the liquid dispensing comb teeth, which enables more precise control of the liquid dispensing volume. At the same time, the moving component pushes the liquid out from multiple liquid dispensing comb teeth, making the liquid discharged from different liquid dispensing comb teeth more uniform, thus improving the quality and stability of the liquid dispensing.

[0036] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0037] It should be noted that when a component is referred to as being "mounted on," "fixed to," or "set on" another component, it can be directly on the other component or may have an intervening component present. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or may have an intervening component present.

[0038] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of this utility model are only relative concepts or are based on the normal use state of the product, and should not be considered as restrictive.

[0039] Hair combing is an integral part of grooming, and combs, as auxiliary tools, make hair combing more convenient. Traditional combs only have the function of ordinary hair combing and cannot meet the needs of users to apply conditioning lotion to their hair or scalp to care for their hair quality. With the large market demand, many manufacturers have launched massage combs.

[0040] One common liquid dispensing mechanism in massage combs involves a spring inside the comb teeth, with a ball bearing at the end of each tooth. The upper end of the spring abuts against other components, while the lower end abuts against the ball bearing. When the ball bearing is compressed, the spring retracts, causing the ball bearing to retract into the comb teeth, allowing the liquid to flow out. However, this method has drawbacks. Firstly, it's difficult to effectively control the liquid dispensing, making it hard to dispense a precise amount. Different compression forces and angles can lead to uneven dispensing.

[0041] To address the shortcomings of existing technologies, this invention provides a liquid outlet structure. Please refer to [link / reference]. Figures 1-9 ,include:

[0042] The housing 1 has a receiving cavity, and a movable component 11 is provided inside the housing 1 to divide the receiving cavity into a first chamber and a second chamber;

[0043] Bottom cover 2, which is disposed at one end of the housing 1, and is provided with a plurality of liquid outlet comb teeth 21;

[0044] A power component 31 drives the moving assembly 11 to adjust 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 21. In the liquid outlet structure 10 of this application, the liquid is located in the first chamber. By driving the moving assembly 11 through the power component 31, the relative volume of the first chamber and the second chamber is adjusted to push the liquid in the first chamber out of the liquid outlet comb 21, which can more accurately control the liquid outlet volume. At the same time, the moving assembly 11 pushes the liquid out of multiple liquid outlet combs 21, making the liquid more evenly discharged from different liquid outlet combs 21, thus improving the quality and stability of the liquid outlet.

[0045] In this application, the power component 31 drives the moving component 5 to move, that is, the power component 31 needs to drive the moving assembly 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 assembly 11 is a straight line. Based on this moving path, the power component 31 can be selected from hydraulic drive mechanism, pneumatic drive mechanism, linear motor mechanism, combination mechanism of motor and linear transmission unit, etc. It should be noted that in this application, the power component 31 does not only refer to power units such as motors, air pumps, and hydraulic pumps, but refers to the mechanism that can drive the moving assembly 11 to move axially within the housing 1.

[0046] In this embodiment, the movable component 11 is fitted inside the housing 1, and the movable component 11 can move axially along the inner wall of the housing 1. When the power component 11 drives the movable component 11 to move, the movable component 11 squeezes the liquid in the first chamber. To prevent the liquid in the first chamber from seeping into the second chamber through the gap between the movable component 11 and the housing 1, and to improve the smoothness of the movement of the movable component 11, at least one first sealing ring 12 is fitted around the periphery of the movable component 11. In this embodiment, three first sealing rings 12 are fitted around the periphery of the movable component 11. Of course, other numbers of sealing rings can also be provided, which is a foreseeable adjustment and is not limited here. Alternatively, when the movable component 11 is fitted inside the housing 1, the periphery of the movable component 11 can also be in direct contact with the inner wall of the housing 1. The outer periphery of the movable component 11 can be made of rubber or other flexible materials to achieve contact with the inner wall of the housing 1, thereby avoiding a gap between the movable component 11 and the housing 1.

[0047] Furthermore, in this embodiment, the bottom cover 2 has external threads on its periphery, and the housing 1 has internal threads on the inner wall of the first chamber. The bottom cover 2 is installed at the lower end of the housing 1 by rotational engagement. In this case, the moving component 11 and the bottom cover 2 respectively confine the liquid within the housing 1 from both ends of the first chamber. The bottom cover 2 is connected to the housing 1 by a threaded rotational engagement, which is simple in structure and easy to assemble and disassemble. Alternatively, the bottom cover 2 can also be installed at the lower end of the housing 1 by a plug-in engagement. Specifically, the upper part of the bottom cover 2 is inserted into the housing 1 and the periphery of the inserted part is tightly fitted against the inner wall of the housing 1. A step is provided on the periphery of the bottom cover 2 to limit the depth of the plug-in engagement. To prevent the liquid in the first chamber from leaking out from the connection between the bottom cover 2 and the housing 1, an annular step is provided at the end of the housing 1 for installing the second sealing ring 22. When the bottom cover 2 and the housing 1 are rotated together, 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 liquid from leaking out from the connection.

[0048] Furthermore, the liquid outlet structure 10 also includes an upper cover 3 disposed at the other end of the housing 1. The power component 31 is located inside the upper cover 3. The power component 31 outputs the medium to the second chamber. The moving component 11 squeezes the first chamber so that the liquid in the first chamber is discharged from the liquid outlet comb 21. In this 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 positional relationship of other components in this application is with reference to this. In addition, axial movement refers to movement in the vertical direction with reference to the positions of the bottom cover 2 and the upper cover 3.

[0049] 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 drives the moving component 11 to move, thereby squeezing the liquid in the first chamber and causing the liquid to be discharged through the liquid outlet comb teeth 21. The advantage of using a pneumatic drive to move the moving component 5 is that by adjusting the pressure and flow of the pneumatic system, the movement speed and stroke of the cylinder can be precisely controlled, thereby accurately controlling the position change of the moving component 11 in the liquid outlet structure 10, realizing precise adjustment of the relative volume of the first and second chambers, and thus accurately controlling the liquid output. The pneumatic mechanism can provide relatively stable linear motion, so that the moving component 11 moves evenly when adjusting the chamber volume, avoiding the situation of fluctuating liquid output due to unstable movement, ensuring that the liquid discharged from the liquid outlet comb teeth 21 is uniform and stable, and improving the user's experience when using the massage comb. The pneumatic mechanism has the characteristics of rapid response. The pneumatic mechanism, when needed, can quickly drive the moving component 11 to dispensing liquid, achieving rapid dispensing; when dispensing is not needed, it can quickly stop, meeting the user's need for timely control of dispensing, especially suitable for situations where users frequently start and stop dispensing liquid as needed. The pneumatic mechanism has a relatively simple and compact structure, making it easy to install in the limited space of the dispensing structure 10 without adding excessive volume and weight, thus maintaining the overall portability of the massage comb. The pneumatic mechanism causes less wear on components and has a longer service life, ensuring that the massage comb's dispensing structure 10 works stably and reliably during long-term use, reducing maintenance and replacement costs due to mechanism failure, and improving the user experience. In contrast, the hydraulic mechanism requires power to be transmitted through hydraulic medium, posing a risk of leakage, increasing the weight of the dispensing structure 10, and having a more complex overall structure with poor response speed; the motor mechanism has a more complex overall structure, occupies more space, and is prone to generating noise during motor operation.

[0050] Furthermore, the moving component 11 includes a triggering unit 4, the triggering end of the triggering unit 4 facing the first chamber. When the triggering unit 4 is triggered, the second chamber communicates with the first chamber, and the moving component 11 moves toward the side where the second chamber is located, so as to adjust the relative volume of the first chamber and the second chamber.

[0051] Based on the aforementioned embodiments, a pneumatic mechanism drives the moving component 11. After the moving component 11 drains the liquid in the first chamber through the liquid outlet comb 21, the volume of the second chamber is at its maximum relative to the first chamber, and the second chamber is filled with gas. In order to reuse the liquid outlet structure 10, i.e., to drain 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 towards the second chamber, so that the first chamber has sufficient volume to accommodate the liquid. At this time, the bottom cover 2 and the housing 1 are rotated relative to each other to disassemble them. The trigger end of the trigger unit 4 is pressed to connect the first chamber and the second chamber. At the same time, the moving component 11 moves towards the second chamber, and the gas in the second chamber can be discharged to the outside through the openings of the first chamber and the housing 1. The trigger unit 4 is equivalent to a pressure relief device, i.e., 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, ensuring that the moving component 11 can move smoothly towards 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.

[0052] Furthermore, the moving component 11 also includes a moving part 5 and an elastic part 6. The trigger unit 4 is axially movable on the moving part 5. The moving part 5 and the trigger unit 4 define a channel connecting the first chamber and the second chamber. The housing 1 is sleeved on the outer periphery of the moving part 5. The elastic part 6 is sleeved on the trigger unit 4 and located between the trigger end of the trigger unit 4 and the moving part 5. When the trigger unit 4 is pressed and the elastic part 6 is compressed, the trigger unit 4 is activated, and the channel is opened. When the elastic part 6 is reset, the channel is closed.

[0053] In this embodiment, a groove is provided on the outer periphery of the movable member 5 for installing the first sealing ring 12. The first sealing ring 12 contacts the inner wall of the housing 1. Under the compression of the movable member 5 and the housing 1, the first sealing ring 12 deforms to separate the first chamber and the second chamber, thereby preventing liquid in the first chamber from seeping into the second chamber when the trigger unit 4 is not pressed. The trigger unit 4 has an overall approximately I-shaped structure. The upper end of the trigger unit 4 is used to open or close the channel connecting the first chamber and the second chamber, and the lower end of the trigger unit 4 is pressed by the user to drive the trigger unit 4 to move axially on the movable member 5. The elastic member 6 is sleeved on the trigger unit 4 axially, and the upper end of the elastic member 6 abuts against the movable member 5, and the lower end of the elastic member 6 abuts against the upper end of the trigger unit 4. When the user presses the lower end of the trigger unit 4, the trigger unit 4 compresses the elastic element 6, and the trigger unit 4 moves axially under the guidance of the moving element 5. During this movement, the upper end of the trigger unit 4 moves upward, opening the channel and connecting the first chamber and the second chamber. After the user releases the trigger unit 4, under the elastic force of the elastic element 6, the trigger unit 4 returns to its initial state, closing 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 component 11, meaning that gas cannot flow between them. The elastic element 6 ensures that after the user releases the trigger unit 4, the trigger unit 4 automatically returns to its original position, and the upper end of the trigger unit 4 closes the channel connecting the first chamber and the second chamber. The structure is ingenious, the control is simple, and the cost is low.

[0054] Furthermore, the moving part 5 has a mounting part 51 arranged along the axial direction in the middle of the moving part 5, and a support part 52 is provided on the inner wall of the mounting part 51 to limit the trigger unit 4 on the moving part 5; the channel includes a guide port 521 located on the support part 52.

[0055] In this embodiment, the moving part 5 has a cylindrical structure with openings at both ends along the axial direction in the middle, namely the mounting part 51, for accommodating the partial extension of the trigger unit 4 and for mounting the trigger unit 4; the support part 52 is approximately an annular structure and is formed by extending from the inner wall of the mounting part 51 towards the middle. The support part 52 divides the space inside the mounting part 51 into upper and lower parts. The upper end of the elastic member 6 extends into the lower space of the mounting part 51, and the upper end of the elastic member 6 abuts against the lower end face of the support part 52. The lower end of the elastic member 6 is located outside the lower space of the mounting part 51 and abuts against the lower end of the trigger unit 4. The upper space of the mounting part 51 is used to accommodate the upper part of the trigger unit 4 and guides the trigger unit 4 to move axially when the lower end of the trigger unit 4 is pressed, ensuring the stability of the movement of the trigger unit 4.

[0056] Furthermore, the triggering unit 4 includes a triggering element 41, a pressing element 42, and a sealing element 43. The fixed end of the triggering element 41 passes through the through hole of the support part 52 and is fixedly connected to the pressing element 42. The sealing element 43 is sleeved on the pressing element 42 and contacts the inner wall of the mounting part 51.

[0057] In this embodiment, the trigger 41 is approximately T-shaped and is disposed upside down on the moving part 5. The fixed end (i.e., the vertical part) of the trigger 41 extends into the upper space of the mounting part 51 through the through hole of the annular support part 52 and is screwed and fixed to the pressing part 42. Under the action of the elastic member 6, the annular support part 52 abuts against the pressing part 42 to dynamically limit the trigger unit 4 to the moving part 5. A limiting part 44 is provided at the lower end of the trigger 41. When the lower end of the trigger 41 is pressed, the limiting part 44 abuts against the lower end of the moving part 5. On the one hand, this protects the elastic member 6 and prevents it from being over-compressed, which would affect its service life. On the other hand, it limits the distance the trigger unit 4 moves axially when opening the channel, which helps to improve the efficiency of opening and closing the channel. Furthermore, the periphery of the limiting part 44 extends toward the moving part 5 with an abutting part 411, and the lower end surface of the moving part 5 is provided with an abutting groove 53 that is adapted to the abutting part 411, so as to avoid left and right swinging when the trigger 41 is pressed into place, thereby improving the user experience; both the abutting part 411 and the abutting groove 53 are annular.

[0058] In one embodiment of this application, when the trigger 41 is not pressed, the sealing member 43, which is sleeved on the outer periphery of the pressing member 42, will contact the inner wall of the mounting part 51 to close the channel. In order to open the channel, the pressing member 42 and the sealing member 43 need to be moved axially by pressing the trigger 41. When the periphery of the sealing member 43 is no longer in contact with the inner wall of the mounting part 51, the channel is opened. Specifically, the sealing member 43 can be positioned higher than the upper end face of the mounting part 51 by pressing the trigger 41. At this time, the gas in the second chamber can enter the first chamber through the guide port 521 and then be discharged to the outside.

[0059] Furthermore, to ensure that when the seal 43 is positioned higher than the upper end face of the mounting portion 51, the periphery of the pressing member 42 contacts the inner wall of the mounting portion 51, or that the gap between the periphery of the pressing member 42 and the inner wall of the mounting portion 51 is too small, affecting the efficiency of gas passage, a chamfered surface 421 can be provided on the lower periphery of the pressing member 42. When the chamfered surface 421 is close to the upper end face of the mounting portion 51, the chamfered surface 421 creates a larger gap between the periphery of the pressing member 42 and the end face of the mounting portion 51, allowing gas to flow more smoothly from the second chamber into the first chamber through the guide port 521. Additionally, 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 serves as a guide during the repositioning process of the pressing member 42, facilitating the re-entry of the pressing member 42 into the mounting portion 51 and ensuring smooth repositioning of the pressing member 42.

[0060] Furthermore, the mounting part 51 is provided with a communication port 54; pressing the trigger member 41 of the trigger unit 4 compresses the elastic member 6 and causes the trigger unit 4 to move, the communication port 54 connects the second chamber and the first chamber through the guide port 521.

[0061] Based on the chamfered surface 421 provided on the lower end periphery of the pressing member 42 in the aforementioned embodiments, in another embodiment of this application, a guide surface 55 adapted to the chamfered surface 421 can be provided on the inner wall of the upper opening of the mounting part 51, and the guide surface 55 is provided along the inner wall of the mounting part 51, the guide surface 55 is circumferentially open and the opening gradually increases from bottom to top; furthermore, a connecting port 54 is provided on the upper periphery of the mounting part 51, when the sealing member 43 on the pressing member 42 moves axially to the height of the guide surface 55, the presence of the guide surface 55 makes the sealing member 43 and the inner wall of the mounting part 51 meet at the guide surface 55. There is a gap at height 5. At this time, the gas in the second chamber can first enter the first chamber through the connecting port 54 and then through the guide port 521. The setting of the chamfered surface 421 and the guide curved surface 55 makes it smoother for the gas to enter the first chamber from the second chamber through the guide port 521. At the same time, the cooperation of the two also plays a guiding role in the resetting process of the pressing part 42. In this embodiment, it is not necessary to push the position of the sealing part 43 to be higher than the upper end surface of the mounting part 51. It is sufficient to make the sealing part 43 at the height of the guide curved surface 55. This is beneficial to improve the working efficiency of the triggering unit 4 and minimize the failure of the triggering unit 4 during operation.

[0062] Furthermore, the pressing member 42 is provided with a guide portion 422 adapted to the communication port 54. In this embodiment, the guide portion 422 is provided on the periphery of the chamfered surface 421. The guide portion 422 is a recessed surface provided on the chamfered surface 421. Its purpose is to further improve the efficiency of gas flow when the second chamber and the first chamber are connected, so that the gas in the second chamber can quickly enter the first chamber through the guide port 521 and be discharged to the outside, thereby achieving rapid pressure relief.
