Description

Technical Field

[0001] The utility model relates to a pneumatic liquid pushing device, a medicine applicator and a comb. Background Art

[0002] Hair care is an indispensable part of modern people's daily beauty and health care. With the improvement of people's hair care needs, various hair care products such as essential oils, hair conditioners and care liquids emerge in an endless stream in the market. These products can not only nourish the hair, but also repair damaged hair quality and improve hair health. However, how to efficiently and evenly apply these care products to the hair has become a major problem.

[0003] The traditional hair care method is usually to pour the care liquid or essential oil into the palm and then apply it to the hair by hand. This method not only easily causes waste of the care liquid, 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, applying the care liquid by hand may also cause the hands to be greasy and the use experience is not good. Content of the Utility Model

[0004] The first object of the utility model is to provide a pneumatic liquid pushing device with precise control and even application.

[0005] The second object of the utility model is to provide a medicine applicator with even application.

[0006] The third object of the utility model is to provide a comb with even application.

[0007] The first object of the utility model is realized as follows:

[0008] A pneumatic liquid pushing device includes a liquid guiding module, an air pump, a liquid storage module and a controller. The liquid storage module is provided with a liquid storage space, the liquid storage space is provided with a liquid discharge port and an exhaust port, and the height of the exhaust port is higher than that of the liquid discharge port;

[0009] The exhaust opening of the air pump is communicated with the exhaust port;

[0010] The liquid guiding module is provided with a liquid guiding inlet and a liquid guiding outlet. The liquid guiding inlet is communicated with the liquid discharge port, and the liquid guiding outlet is communicated with the liquid guiding inlet;

[0011] The controller is electrically connected to the air pump. The controller controls the operation of the air pump. When the air pump is started, the air pump extracts external gas and then enters the liquid storage space through the exhaust port, increasing the pressure in the liquid storage space, so that the gas pushes the liquid in the liquid storage space through the liquid discharge port, the liquid guiding inlet into the liquid guiding module, and finally discharges through the liquid guiding outlet.

[0012] The external gas is pumped by an air pump and introduced into the liquid storage space, increasing the air pressure in the liquid storage space, so that the liquid is evenly pushed to the liquid guiding module under the action of the gas pressure, effectively solving the problem of uneven liquid coating in traditional manual operation and improving the accuracy and stability of liquid output.

[0013] Since the liquid is pushed under the action of air pressure, the liquid in the liquid storage space can be discharged more thoroughly, avoiding the liquid remaining at the bottom of the liquid storage bottle, thereby reducing waste and improving the resource utilization efficiency.

[0014] The start and stop of the air pump are controlled by a controller, and the operation is simple. Users can easily achieve precise control of the liquid, avoiding the greasiness and inconvenience in manual operation and improving the overall user experience.

[0015] The device adopts the air pressure liquid pushing method, and even relatively viscous liquids can be smoothly pushed, increasing the applicability of the device and meeting the requirements of different usage scenarios.

[0016] By reasonably designing the height difference between the liquid discharge port and the exhaust port, it is ensured that when the air pump works, the gas preferentially enters the upper part of the liquid storage space, and the liquid is stably output from the liquid discharge port under the action of air pressure, avoiding the phenomenon of gas-liquid mixing and improving the stability and continuity of the liquid discharge process.

[0017] The first object of the present utility model can also be solved by the following technical measures:

[0018] Further, a nozzle connection cavity is provided at the position corresponding to the liquid storage space of the liquid storage module, and the nozzle connection cavity is communicated with the liquid storage space.

[0019] By providing the nozzle connection cavity, the liquid storage bottle can be quickly connected or detached from the device, facilitating the replacement of different types or different volumes of liquids, improving the usage flexibility and meeting the diverse nursing needs.

[0020] The design of the nozzle connection cavity ensures the tight connection between the liquid storage bottle and the device, avoiding the problem of liquid leakage caused by poor connection, and at the same time ensuring the safe storage of the liquid and preventing it from being contaminated by the outside during the use process.

[0021] Users only need to insert the nozzle of the liquid storage bottle into the connection cavity to complete the loading of the liquid, simplifying the operation steps, lowering the usage threshold and enhancing the user experience.

[0022] The nozzle connection cavity is directly communicated with the liquid storage space, so that the air pressure generated by the air pump can directly act on the liquid storage space, effectively pushing the liquid to quickly flow to the liquid guiding module, improving the liquid discharge efficiency and reducing the waiting time.

[0023] This design is suitable for liquid storage bottles of various specifications, which improves the compatibility of the device. At the same time, its stable structural design also ensures consistent liquid pushing effects during long-term use. It is suitable for use in various scenarios such as home care and beauty salons.

[0024] Furthermore, the liquid storage module includes a bottle mouth connecting seat and a liquid storage bottle, the bottle mouth connecting seat is provided with a bottle mouth connecting cavity, the bottle mouth connecting cavity is provided with the liquid discharge port and the air exhaust port, the bottle mouth of the liquid storage bottle clamps the bottle mouth connecting cavity, and the inner cavity of the liquid storage bottle forms the liquid storage space.

[0025] The design of the bottle mouth connection seat and the bottle mouth connection cavity ensures that the liquid storage bottle can be firmly connected to avoid liquid leakage caused by looseness or mismatch, thereby improving the safety and service life of the device.

[0026] The mouth of the liquid storage bottle cooperates with the bottle mouth connecting cavity by clamping. The user only needs simple operation to complete the installation or disassembly, which greatly facilitates the replacement of the liquid storage bottle. It is especially suitable for the scene that needs to frequently change different liquids.

[0027] Through the clamping design of the bottle mouth, the liquid storage bottle and the bottle mouth connecting cavity can fit tightly, which enhances the sealing of the system, prevents outside air from entering the liquid storage space, ensures that the liquid can be discharged smoothly, and improves the use efficiency.

[0028] The bottle mouth connection cavity can be designed and adjusted according to different liquid storage bottles. It has good adaptability and is compatible with liquid storage bottles of different specifications and capacities to meet a variety of application requirements.

[0029] Furthermore, the liquid discharge port is provided at the lowest point of the liquid storage space.

[0030] Further, the bottle mouth connecting seat includes a base, the base is provided with the bottle mouth connecting cavity, the bottom of the bottle mouth connecting cavity is provided with the discharge port and the exhaust pipe, one end of the exhaust pipe extends toward the outside of the base to form an exhaust inlet, the other end of the exhaust pipe extends toward the bottle mouth connecting cavity to form an exhaust outlet, the exhaust inlet and the exhaust outlet are connected to form the exhaust port, and the exhaust opening of the air pump is connected to the exhaust inlet.

[0031] By setting up an exhaust pipe and connecting the exhaust opening of the air pump with the exhaust port in the liquid storage bottle, the gas can smoothly enter the liquid storage bottle through the exhaust pipe. This design not only effectively improves the efficiency of gas entering the liquid storage space, but also ensures that the air pressure in the liquid storage space can quickly reach an ideal state, thereby more efficiently promoting the flow of the care solution and ensuring the stable output of the care solution during spraying and coating.

[0032] The setting of the exhaust pipe realizes the separation of the liquid discharge port and the exhaust port, avoiding the mixing of gas and liquid during the flow process and preventing the liquid from flowing back to block the exhaust passage. This design further improves the operation stability of the device and reduces the failures and maintenance problems that may be caused by the mixing of gas and liquid.

[0033] The exhaust inlet and the exhaust outlet of the exhaust pipe extend in different directions respectively, which can better guide the air flow into a specific position of the liquid storage bottle, avoiding the ineffective diffusion of the air flow. This design enables the air pump to more efficiently control the air flow path during operation, ensuring the stability of the air pressure, and thus accurately adjusting the output volume and spraying effect of the nursing liquid.

[0034] The nozzle connection seat adopts a base structure, integrating a nozzle connection cavity, a liquid discharge port and an exhaust pipe. The overall design is compact and easy to assemble and disassemble.

[0035] Furthermore, the nozzle connection seat further includes an elastic pad, which is placed in the nozzle connection cavity, and the elastic pad located on the side wall of the nozzle connection cavity is provided with a threaded inner wall;

[0036] The elastic pad located on the bottom wall of the nozzle connection cavity is provided with a diversion port corresponding to the position of the liquid discharge port, and the diversion port is communicated with the liquid discharge port;

[0037] The elastic pad located on the bottom wall of the nozzle connection cavity is provided with a socket corresponding to the position of the exhaust pipe, and the exhaust pipe passes through the socket of the elastic pad and extends into the nozzle connection cavity.

[0038] The elastic pad arranged in the nozzle connection seat is tightly matched with the nozzle through the threaded inner wall, effectively improving the sealing performance between the nozzle and the connection cavity and preventing the nursing liquid from leaking during use. At the same time, the softness of the elastic pad makes the connection between the nozzle and the connection seat more firm, and it can still maintain a good sealing effect even under long-term use or external force.

[0039] The elastic pad adopts a threaded structure design and has elasticity, which can adapt to the nozzles of different sizes of liquid storage bottles, enabling the medicine applicator to have wide applicability and being able to flexibly match various specifications of liquid storage bottles on the market.

[0040] The threads of the liquid storage bottle nozzle and the threads of the elastic pad are engaged with each other, ensuring that the nozzle is tightly locked in the nozzle connection cavity, thereby improving the sealing effect, preventing liquid leakage, and ensuring the safety and stability during use.

[0041] The elastic pad adopts a threaded structure design and is made of elastic material, which simplifies the production process, reduces the manufacturing cost, and can also ensure efficient sealing and fixing effects.

[0042] The threaded structure design enables the liquid storage bottle to be easily screwed into or out of the nozzle connection cavity, making it more convenient for users to replace the liquid storage bottle and greatly improving the use experience.

[0043] The bottle mouth is threadedly engaged with the elastic pad, further locking the position of the liquid storage bottle, preventing loosening caused by vibration or extrusion during use, and ensuring the structural stability and service life of the device.

[0044] Furthermore, a one-way valve for preventing liquid from entering the air pump through the exhaust port is provided between the exhaust opening and the exhaust port of the air pump.

[0045] The setting of the one-way valve effectively prevents the nursing liquid from flowing back into the air pump through the exhaust port under conditions such as air pressure fluctuations or device tilting. Once the air pump is filled with liquid, it may cause damage or performance degradation. The one-way valve can avoid this situation, thereby extending the service life of the air pump and improving the overall reliability of the device.

[0046] The one-way valve can ensure that gas only flows into the liquid storage bottle unidirectionally, thereby avoiding unstable liquid supply caused by air pressure drop or fluctuations when the air pump stops working. This design makes the air pressure in the liquid storage bottle more stable, and the nursing liquid can be output more evenly and continuously, improving the smearing effect and user experience.

[0047] The entry of liquid into the air pump may cause short circuits, motor damage or other failures, especially more significantly after long-term use or multiple uses. The addition of the one-way valve improves the safety of the device, prevents device failures caused by liquid backflow, and reduces maintenance costs and usage risks.

[0048] During use, users do not need to worry about the problems of air pump damage and liquid supply interruption caused by liquid backflow, which improves the stability of the product and the user's trust in the device. The good anti-backflow design enables users to perform hair care more easily and freely, enhancing the overall use experience.

[0049] The second object of the present utility model is achieved as follows:

[0050] An applicator using a pneumatic liquid pushing device further includes a hollow top cover, a housing that is vertically penetrated, and a battery. The air pump, the liquid storage module, the controller, and the battery are disposed in the housing, and the battery supplies power to the controller and the air pump;

[0051] The hollow top cover is detachably disposed on the top of the housing, and a liquid storage bottle accommodating cavity is formed in the inner cavity of the hollow top cover;

[0052] The liquid guiding module is detachably disposed at the bottom of the housing.

[0053] Both the hollow top cover and the liquid guiding module adopt a detachable design, which is convenient for users to replace the liquid storage bottle.

[0054] By compactly arranging the air pump, liquid storage module, controller and battery in the shell, the overall structure becomes more concise and orderly, which effectively improves the utilization rate of the internal space, reduces the size of the device, and facilitates carrying and use.

[0055] The hollow top cover accommodates the liquid storage bottle, which is reasonably designed and easy to replace. Users only need simple operations to complete the replenishment of the liquid medicine, which reduces the operation steps and improves the convenience and efficiency of use.

[0056] Batteries are used to power the air pump and controller, freeing the device from the constraints of power cords. This makes the device suitable for mobile use in different scenarios and meets the needs of medication in various environments.

[0057] The third purpose of the utility model is achieved in this way:

[0058] A comb using a pneumatic liquid pushing device also includes a comb body, the comb body includes a handle portion and a comb tooth portion, the air pump, a liquid storage module, a controller and a battery are placed in the comb body, the battery supplies power to the controller and the air pump, the comb tooth portion is provided with a liquid guide module installation cavity, the liquid guide module is detachably arranged in the liquid guide module installation cavity, and the liquid guide inlet of the liquid guide module is connected to the liquid discharge port.

[0059] The air pump, liquid storage module, controller and battery are integrated into the comb body, so that the comb has the function of pushing liquid. Users can evenly apply liquid (such as nutrient solution, medicine solution) while combing their hair, which improves the convenience of use and is suitable for hair care or treatment scenarios. The liquid guide module adopts a detachable design, which can be easily disassembled by users for cleaning, replacement or maintenance, ensuring the hygiene of the comb and extending the service life of the device.

[0060] Multiple functional components are compactly arranged inside the comb body, and the structural design is reasonable. While ensuring full functionality, the comb remains portable, making it suitable for daily carrying and use.

[0061] The liquid guide module is installed on the comb teeth, and the liquid is accurately guided out through the liquid guide port to ensure that the liquid is evenly distributed between the comb teeth, achieving an efficient application effect and avoiding liquid waste or uneven application.

[0062] The battery-powered design allows the comb to be used flexibly in different environments without the restriction of a power cord, which increases the mobility and convenience of the device and is particularly suitable for use outside.

[0063] The beneficial effects of the utility model are as follows:

[0064] In this utility model, an external gas is extracted by an air pump and introduced into the liquid storage space, increasing the air pressure in the liquid storage space. As a result, the liquid is evenly pushed to the liquid guiding module under the action of the gas pressure, effectively solving the problem of uneven liquid application in traditional manual operations and improving the accuracy and stability of liquid output.

[0065] In this utility model, since the liquid is pushed under the action of air pressure, the liquid in the liquid storage space can be discharged more thoroughly, avoiding the liquid remaining at the bottom of the liquid storage bottle, thus reducing waste and improving the resource utilization efficiency.

[0066] In this utility model, the nozzle of the liquid storage bottle is connected to the nozzle connection cavity by a clamping method, and the user can complete the installation or disassembly with simple operations, greatly facilitating the replacement of the liquid storage bottle, especially suitable for scenarios where different liquids need to be frequently replaced.

[0067] In this utility model, the elastic pad provided in the nozzle connection seat is in close fit with the nozzle through the inner wall of the thread, effectively improving the sealing performance between the nozzle and the connection cavity and preventing the nursing liquid from leaking during use. At the same time, the softness of the elastic pad makes the connection of the nozzle more firm, and even under long-term use or external force, it can still maintain a good sealing effect.

[0068] In this utility model, the setting of the one-way valve effectively prevents the nursing liquid from flowing back into the air pump through the exhaust port under conditions such as air pressure fluctuations or equipment tilting. Once the air pump admits liquid, it may cause damage or performance degradation. The one-way valve can avoid this situation, thereby extending the service life of the air pump and improving the overall reliability of the equipment.

[0069] In this utility model, the air pump, liquid storage module, controller, and battery are integrated into the comb body, enabling the comb to have a liquid pushing function. When the user combs their hair, they can simultaneously apply the liquid (such as nutrient solution, medicinal liquid) evenly, improving the convenience of use and being applicable to hair care or treatment scenarios.

[0108] How the user replaces the liquid storage bottle 41

[0109] Remove the hollow top cover 6: First, the user removes the hollow top cover 6 from the top of the housing 1.

[0110] Take out the old liquid storage bottle 41: After removing the hollow top cover 6, the liquid storage bottle 41 will be exposed, and the user can easily take out the old liquid storage bottle 41 from the decorative cover.

[0111] Replace with a new liquid storage bottle 41: Connect the nozzle of the new liquid storage bottle 41 to the nozzle connection cavity 51 mouth-to-mouth. The nozzle is threadedly connected, and the user can tighten the liquid storage bottle 41 to ensure a seal.

[0112] Install the hollow top cover 6: Reinstall the hollow top cover 6 on the top of the housing 1 to complete the replacement.

[0113] The process by which the user starts the air pump 3 to drain the liquid can be achieved through the following steps:

[0114] Install the liquid storage bottle 41: First, install the liquid storage bottle 41 filled with the nursing solution in the pneumatic medicator, ensure that the nozzle is tightly clamped within the nozzle connection cavity 51, and make the nozzle sealing film be pierced by the piercing portion 55 of the exhaust pipe 53 to ensure that the liquid can flow smoothly into the liquid discharge port 511.

[0115] Turn on the device: The user presses the power switch 82 on the outside of the housing 1 to connect the power supply of the air pump 3.

[0116] Start the air pump 3: After the power is turned on, when the user touches the scalp with the liquid guiding module 2, the liquid guiding module 2 drives the elastic plug socket 7 to act to touch or move away from the function switch 81 to control the start and stop of the air pump 3.

[0117] The air pump 3 operates to generate air pressure: After the air pump 3 is started, it draws air from the outside, and the air flow enters the liquid storage space within the liquid storage bottle 41 through the exhaust pipe 53. As the air pressure within the liquid storage space increases, the liquid is pressurized and flows into the liquid guiding module 2 via the liquid discharge port 511.

[0118] The liquid is discharged and applied: The nursing solution is discharged through the liquid discharge outlet 22 of the liquid guiding module 2, and the user can adjust the operating speed or start / stop of the air pump 3 according to requirements, thereby controlling the amount of sprayed liquid and the spraying range to achieve the effect of evenly applying the nursing solution.

[0119] Turn off the device: After use, the user presses the power switch 82 to turn off the entire device.

[0120] When the air pump 3 is started, the working principle of liquid discharge

[0121] The air pump 3 operates: The air pump 3 extracts air from the outside to generate an air current. The air current passes through the exhaust opening of the air pump 3 and enters the liquid storage space of the liquid storage bottle 41 via the exhaust pipeline 53.

[0122] Increase the air pressure in the liquid storage space: As the air pump 3 continuously injects gas into the liquid storage bottle 41, the air pressure in the liquid storage space gradually increases. This process forms a pressure difference higher than the outside in the liquid storage space.

[0123] The liquid is pushed to flow: As the air pressure in the liquid storage space increases, the gas exerts pressure on the nursing liquid in the liquid storage bottle 41. Since the liquid discharge port 511 is located at the bottom of the bottle mouth connection cavity 51, the liquid is pushed downward under the action of the pressure, flows through the liquid discharge port 511, and enters the liquid guide inlet 21 of the liquid guide module 2.

[0124] The liquid guide module 2 distributes the liquid: After the nursing liquid enters the liquid guide module 2, it first flows into the liquid distribution cavity 23. The design of the liquid distribution cavity 23 can effectively distribute the liquid so that it evenly flows to multiple liquid guide openings 231 in the liquid guide module 2.

[0125] The liquid is ejected: The nursing liquid is discharged through the hollow liquid guide column 24 and the liquid guide outlet 22 to achieve uniform spraying. At this time, the user can control the amount and intensity of the sprayed liquid by adjusting the start-stop or speed of the air pump 3.

[0126] Anti-backflow protection: To prevent the liquid from flowing back into the air pump 3, a one-way valve is provided between the exhaust port 512 and the exhaust opening of the air pump 3 to ensure that the liquid can only flow in one direction and avoid damage to the air pump 3 caused by liquid backflow.

[0127] Liquid discharge working principle

[0128] After the nursing liquid enters the liquid guide module 2, it first passes through the liquid distribution cavity 23. The bottom wall of the liquid distribution cavity 23 is provided with multiple liquid guide openings 231 where the liquid is distributed.
