Description

Technical Field

[0001] The utility model relates to a modular component of a medicine applicator. Background Art

[0002] Hair care is an essential part of modern daily beauty and health care. With the increasing demand for hair styling, various hair care products such as essential oils, hair conditioners, care liquids, and hair care medicaments are emerging in the market. These products can not only nourish the hair but also repair damaged hair quality and improve hair health. However, how to apply these care products to the hair efficiently and evenly has become a major problem.

[0003] Traditional hair care methods usually involve pouring the care liquid / medicament or essential oil into the palm and then applying it to the hair manually. This method not only easily causes waste of the care liquid / medicament but also is difficult to apply evenly. Especially when applying to the hair roots and scalp, it is difficult to achieve precise control. In addition, manually applying the care liquid / medicament may also cause the hands to become greasy, resulting in a poor user experience.

[0004] In existing scalp care devices, there is no assembly relationship among parts such as the liquid pumping pump, battery, and controller. Parts such as the liquid pumping pump, battery, and controller need to be separately arranged in the housing of the scalp care device, with complex assembly and high costs.

[0008] The seat body module is provided with a nozzle connection cavity for connecting a liquid storage bottle and a liquid discharge port for discharging liquid, and the liquid discharge port is communicated with the nozzle connection cavity;

[0009] The seat body module is fixedly arranged in the seat body module installation area;

[0010] The liquid pumping pump is fixedly arranged in the liquid pumping pump installation area, and the inlet of the liquid pumping pump is communicated with the liquid discharge port;

[0011] The controller is fixedly arranged in the controller installation area;

[0012] The battery is fixedly arranged in the battery installation area;

[0013] The plugging device is provided with an upper plug interface and a lower plug interface for connecting a liquid guiding module or draining liquid. The upper plug interface and the lower plug interface are communicated. The plugging device is arranged on the bracket and located below the controller;

[0014] The outlet of the liquid pumping pump is communicated with the upper plug interface;

[0015] The battery, the controller and the liquid pumping pump are electrically connected. The battery supplies power to the controller and the liquid pumping pump. The controller controls the start / stop and / or speed regulation of the liquid pumping pump.

[0016] This design integrates the liquid pumping pump, the seat body module, the battery, the controller and the bracket into a modular component. Each functional module is reasonably distributed in different areas of the bracket, which is convenient for assembly, disassembly and replacement, and reduces the production and maintenance costs.

[0017] By fixing the battery, the liquid pumping pump, the controller and the plugging device in different areas, the internal space is fully utilized, making the whole modular component structure compact and improving the stability and reliability of the equipment.

[0018] The plugging device is provided with an upper plug interface and a lower plug interface, which supports flexible connection with the liquid guiding module or the liquid draining device, simplifies the operation process and improves the use experience.

[0019] Through the integration of the controller, the battery supplies power to the liquid pumping pump and the controller. The controller can accurately control the start / stop and speed regulation of the liquid pumping pump to ensure the convenience and smoothness of the operation.

[0020] The modular design provides a greater space for the function expansion and performance upgrade of subsequent products. Only by replacing or upgrading a single module can the product be updated, without major modification to the whole machine.

[0021] The controller can control the working mode of the liquid pumping pump in various ways, with better user experience. At the same time, this design also helps to improve the operation accuracy and nursing effect.

[0022] The object of the utility model can also be solved by the following technical measures:

[0023] Further, the bracket includes an upper bracket and a lower bracket. The battery installation area is arranged on the left side of the upper bracket, the liquid pumping pump installation area is arranged on the right side of the upper bracket, the seat body module installation area is arranged on the top of the upper bracket, and the controller installation area is arranged on the bottom of the upper bracket;

[0024] The upper bracket is provided with an upper connecting column, and the upper connecting column extends upward to connect the seat body module;

[0025] The lower bracket is provided with a lower connecting column, and the lower connecting column passes through the controller to connect the upper bracket.

[0026] The layered design of the upper and lower brackets allows the orderly distribution of functional areas such as the battery, liquid pump, controller, and seat module, which simplifies the installation and maintenance process and improves the stability of the components and the ease of operation.

[0027] Through the design of the upper connecting column and the lower connecting column, the upper bracket and the lower bracket can be firmly connected to ensure the firmness of the overall structure of the modular component and effectively avoid the problem of looseness caused by vibration or use.

[0028] The reasonable layering and connection design of the upper and lower brackets maximizes the internal space utilization, makes the component layout more compact, and effectively controls the overall equipment size to adapt to a wider range of application scenarios.

[0029] Through the partition connection of the upper and lower brackets, when the user replaces or maintains a specific module, there is no need to disassemble the entire device, but only to operate a certain part, which improves the maintainability and scalability of the product.

[0030] The lower connecting column passes through the controller and connects to the upper bracket to form an integral and stable support, further enhancing the strength and durability of the modular components and ensuring stable performance during long-term use.

[0031] Furthermore, the plug-in device comprises an elastic plug-in seat and a locking hoop, the elastic plug-in seat is provided with the upper plug-in interface and the lower plug-in interface, and the upper plug-in interface and the lower plug-in interface are connected;

[0032] The liquid pump is also provided with a hollow upper plug-in terminal connected to the outlet;

[0033] The liquid guide module is provided with a hollow lower plug-in terminal, and the hollow lower plug-in terminal is provided with the liquid guide inlet;

[0034] The hollow upper plug-in terminal is inserted into the upper plug-in interface, the locking hoop is sleeved on the elastic plug-in seat, and the locking hoop and the hollow upper plug-in terminal clamp the elastic plug-in seat together;

[0035] The hollow lower plug-in terminal is inserted into the lower plug-in interface.

[0036] The locking hoop design effectively solves the problem that the hollow upper plug-in terminal may be separated from the elastic plug-in seat due to vibration or improper operation during the liquid guiding process. The locking hoop firmly fixes the hollow upper plug-in terminal through the tightening action to ensure the stability of the connection, thereby avoiding the leakage of the care solution / medicine solution or the interruption of the liquid supply due to loosening.

[0037] During the liquid conduction process, continuous liquid flow needs to be maintained inside the device. The locking hoop prevents loosening or detachment at the connection, thus ensuring a firm connection between the liquid conduction module and the liquid extraction pump, ensuring that the nursing liquid / medicine liquid can smoothly pass through the entire system, and improving the reliability of overall use.

[0038] The clamping effect of the locking hoop further enhances the sealing performance of the plugging device, avoiding liquid leakage caused by unstable connection. Especially during long-term use or under pressure fluctuations, the tightness of the liquid path system can also be maintained.

[0039] Through the design of the elastic plugging seat, the plugging device has a certain elastic buffering effect, which can effectively absorb vibration and impact, avoiding problems such as interface loosening or liquid leakage caused by external forces during use, and ensuring a smooth and stable flow path for the nursing liquid / medicine liquid.

[0040] Under the modular design, users can easily replace different liquid conduction modules. They can complete the replacement of components by simply operating the plugging device, which improves the flexibility and adaptability of the device and meets different nursing needs.

[0041] Furthermore, the elastic plugging seat is a silicone elastic plugging seat.

[0042] The elastic plugging seat made of silicone material has excellent elasticity and durability. It can maintain good elastic deformation during repeated use, reduce wear or damage caused by frequent plugging and unplugging, and thus extend the service life of the equipment.

[0043] Silicone material has good flexibility and sealing performance. When cooperating with other components, it can effectively seal the gap, further improving the waterproof effect of the equipment and preventing liquid from leaking into key electronic components.

[0044] The flexible characteristics of the silicone elastic plugging seat enable it to adapt to plugging ends of different sizes, enhancing the versatility and compatibility of the plugging device, and ensuring a smooth and stable plugging process.

[0045] Compared with other high-strength materials, silicone material has a lower cost and is easy to process and form, which helps to control production costs and improve the market competitiveness of products.

[0046] Silicone material has a soft touch. Users can obtain a more comfortable touch feeling during operation. Especially during the process of the liquid conduction module contacting the scalp, it can provide a more gentle nursing experience.

[0047] Furthermore, the modular component further includes a pressing plate. The lower bracket is provided with a lower opening whose diameter is larger than the lower end of the elastic plugging seat. The elastic plugging seat is seated on the lower bracket. The pressing plate is fixed on the lower bracket. The pressing plate and the lower bracket jointly clamp the elastic plugging seat, and the lower end of the elastic plugging seat passes through the lower opening and extends outwards.

[0048] The lower bracket is provided with a lower opening whose diameter is larger than the lower end of the elastic socket, leaving sufficient space. The freely swinging space designed for the elastic socket enables it to adapt and adjust according to different head shapes, ensuring a more fitting contact between the liquid guiding module and the scalp, and enhancing the comfort during the nursing process. This design not only enhances the user experience but also avoids the waste of nursing solution / medicine or poor effects caused by uneven contact.

[0049] Furthermore, the controller is a control circuit board, and the control circuit board is provided with a function switch. The function switch faces the elastic socket, and the elastic socket moves to touch or move away from the function switch, thereby controlling the start / stop and / or speed regulation of the liquid pumping pump.

[0050] The movement of the elastic socket directly touches or moves away from the function switch, which can realize the automatic start / stop or speed regulation of the liquid pumping pump, improving the intelligent level of the device and making the operation simpler and more convenient.

[0051] During use, the user does not need to frequently manually control the switch. When the liquid guiding module contacts the scalp, the elastic socket automatically starts the device, bringing a smoother and more comfortable nursing experience.

[0052] Furthermore, the controller is a control circuit board, and the control circuit board is provided with a power switch and a charging socket.

[0053] Integrating the power switch and the charging socket on the control circuit board makes the control module more compact, reduces external connections and complex wiring, and improves the simplicity and reliability of the overall structure.

[0054] The user can conveniently control the power supply / turn-off of the device directly through the power switch. At the same time, when the battery power is insufficient, the charging socket can be directly used to charge the device. The operation is simple and convenient, improving the user experience.

[0055] The integrated design makes it simpler to maintain and replace components in case of faults, facilitating quick repair and reducing the maintenance cost.

[0056] Furthermore, it further includes a housing. The modular component is placed in the inner cavity of the housing. The housing is provided with a button corresponding to the position of the power switch, and the housing has an opening corresponding to the position of the charging socket. A detachable waterproof seal is provided at the opening.

[0057] The detachable waterproof seal is provided at the opening of the housing, effectively preventing liquid or moisture from entering the device, protecting the circuit and electronic components, ensuring the normal operation of the device in a humid environment, and improving the waterproof level of the device.

[0058] The button design on the housing corresponds to the power switch, allowing users to easily control the device's power on / off through the external button without directly contacting the internal components, making the operation more intuitive and convenient.

[0059] • The opening on the housing provides an external channel for the charging socket. During charging, simply remove the waterproof seal plug to perform the charging operation, enhancing the user experience. After charging is completed, the seal plug can be quickly reset to ensure that the device continues to maintain good waterproof performance.

[0060] The housing provides good physical protection, safely placing the modular components in the inner cavity, effectively isolating dust, moisture, and other harmful substances in the external environment, extending the service life of the device. Moreover, the detachable waterproof seal plug design ensures the waterproof effect.

[0061] The beneficial effects of the present utility model are as follows:

[0062] In the present utility model, the liquid pumping pump, the seat body module, the battery, the controller, and the bracket are integrated into a modular component. Each functional module is reasonably distributed in different areas of the bracket, facilitating assembly, disassembly, and replacement, and reducing production and maintenance costs.

[0063] In the present utility model, by fixing the battery, the liquid pumping pump, the controller, and the plugging device in different areas, the internal space is fully utilized, making the entire modular component structure compact, and improving the stability and reliability of the device.

[0064] In the present utility model, the lock hoop design effectively solves the problem that the hollow upper plugging end may be detached from the elastic plugging seat during the liquid guiding process due to vibration or improper operation. Through the fastening effect, the lock hoop firmly fixes the hollow upper plugging end, ensuring the stability of the connection, thereby avoiding the leakage of the nursing liquid / medicine liquid or the interruption of liquid supply caused by loosening.

[0065] In the present utility model, the lower bracket is provided with a lower opening with a diameter larger than the lower end of the elastic plugging seat, leaving sufficient space. The freely swinging space designed by the elastic plugging seat enables it to adapt and adjust according to different head shapes, ensuring a more fitting contact between the liquid guiding module and the scalp, and enhancing the comfort during the nursing process. This design not only enhances the user experience but also avoids the waste of the nursing liquid / medicine liquid or poor effect caused by uneven contact. Description of the Drawings

The bottle mouth is connected to the thread 331, and the user can tighten the liquid storage bottle 400 to ensure sealing.

[0120] Install the hollow top cover 5: Reinstall the hollow top cover 5 on the top of the housing 1, align the positions of the card block 52 and the card slot 302, and gently press and rotate until a locking sound is heard to complete the replacement.

[0121] The operation steps for the user to start the medicator

[0122] Turn on the power switch 42: Press the button 12 on the housing 1 to turn on the power switch 42 of the medicator. At this time, the battery 100 starts to supply power to the controller 4 and the liquid extraction pump 7, and the device enters the standby state.

[0123] Contact the liquid conduction module 2 to the scalp: Place the medicament applicator on the scalp, ensuring that the hollow liquid conduction column 25 of the liquid conduction module 2 contacts the scalp.

[0124] The liquid conduction module 2 moves upward to activate the liquid pumping pump 7: When the liquid conduction module 2 contacts the scalp, the liquid conduction module 2 will move slightly upward. At this time, the elastic socket 61 moves and touches the function switch 41, and the controller 4 then activates the liquid pumping pump 7. The liquid pumping pump 7 pumps out the nursing liquid in the liquid storage bottle 400 and evenly releases it onto the scalp through the liquid conduction module 2.

[0125] Liquid drainage working principle

[0126] After the liquid pumping pump 7 is activated, through the connected liquid conduction tube 202, the nursing liquid in the liquid storage bottle 400 is extracted from the bottle mouth connection cavity 31 and transported to the hollow lower socket end 23 of the liquid conduction module 2.

[0127] After the nursing liquid enters the liquid conduction module 2, it first passes through the liquid distribution cavity 24. The bottom wall of the liquid distribution cavity 24 is provided with a plurality of liquid conduction openings 13, and the liquid is distributed here.

[0128] The conical part 26 and the first liquid flow channel 27 and the second liquid flow channel 28 therein in the liquid distribution cavity 24 can control the flow rate and flow direction of the liquid to ensure the uniform distribution of the nursing liquid.

[0129] The nursing liquid is finally evenly discharged through the liquid conduction outlet 22 of the hollow liquid conduction column 25 to achieve the effect of nursing the scalp.

[0130] Waterproof principle of the medicament applicator

[0131] Sealed design of the housing 1: The modular components 200 inside the housing 1 are sealed by the sealing ring 201. Especially at the connection gap between the housing 1 and the modular components 200, the sealing ring 201 is used to prevent liquid from seeping in.

[0132] Waterproof sealing plug 131: A detachable waterproof sealing plug 131 is provided at the charging socket 43 of the housing 1. When the user does not use the charging socket 43, cover the sealing plug to prevent moisture from entering the internal circuit.

[0133] The above multiple waterproof measures ensure that the medicament applicator has good waterproof performance during use and can work properly even in a humid environment.
