Description

Technical Field

[0001] The utility model relates to a pneumatic medicine applicator. Background Art

[0002] Hair care is an indispensable part of modern daily beauty and health care. With the improvement of people's hair care needs, various hair care products such as essential oils, hair conditioners, care liquids, and hair care medicated 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] Traditional hair care methods usually pour the care liquid / medicated 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 / medicated 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 / medicated liquid by hand may also cause the hands to become greasy, resulting in a poor use experience. Content of the Utility Model

[0004] The purpose of the utility model is to provide a pneumatic medicine applicator with precise control and even application.

[0005] The purpose of the utility model is achieved as follows:

[0006] A pneumatic medicine applicator includes a housing, a liquid guiding module, an air pump, a liquid storage module, and a controller. The liquid storage module includes a nozzle connection seat. The nozzle connection seat is placed in the inner cavity of the housing. The nozzle connection seat is provided with a nozzle connection cavity. The nozzle connection cavity is provided with a liquid discharge port and an exhaust port. The height of the exhaust port is higher than that of the liquid discharge port. The nozzle connection cavity is exposed outside the housing.

[0007] The air pump is placed in the housing, and the exhaust opening of the air pump communicates with the exhaust port.

[0008] The liquid guiding module is provided with a liquid guiding inlet and a liquid guiding outlet. The liquid guiding inlet communicates with the liquid discharge port. The liquid guiding outlet communicates with the liquid guiding inlet. The liquid guiding outlet and the liquid guiding inlet are in communication.

[0009] The controller is placed in the housing. The controller is electrically connected to the air pump, and the controller controls the operation of the air pump.

[0010] Through the design of the air pump, the spraying amount of the care liquid can be precisely controlled, and the care products can be evenly applied to the hair through the liquid guiding module. Especially for the hair roots and scalp, a more precise care effect can be achieved, avoiding the unevenness and difficulty in coverage of traditional manual application.

[0011] Compared with manual application, the pneumatic medicine applicator can utilize the nursing solution / medicine more efficiently, reducing waste caused by uneven application and hand residue. At the same time, the user can adjust the usage amount of the nursing solution more flexibly to achieve the best nursing effect.

[0012] This design avoids the problem of greasy hands during the traditional manual application process. The user does not need to directly contact the nursing solution during operation, providing a cleaner and more convenient usage experience. At the same time, the operation is simple and convenient, suitable for daily use by different groups of people.

[0013] The pneumatic medicine applicator integrates an air pump, a liquid guiding module, a liquid storage module, and a controller in a housing. The overall design is compact and lightweight, making it easy to carry. Whether at home or traveling, it can be used conveniently to meet daily nursing needs.

[0014] Through the intelligent control of the controller, the user can adjust the spraying time and intensity according to needs to achieve personalized nursing. At the same time, the automated design reduces human operation errors, making the nursing process more stable and reliable.

[0015] The object of the present utility model can also be solved by the following technical measures:

[0016] Further, the liquid storage module further includes a liquid storage bottle. The nozzle of the liquid storage bottle is clamped to the nozzle connection cavity, and the inner cavity of the liquid storage bottle forms a liquid storage space;

[0017] When the air pump is started, the air pump extracts external gas and 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 to enter the liquid guiding module through the liquid discharge port and the liquid guiding inlet, and finally discharges through the liquid guiding outlet.

[0018] By introducing external gas into the liquid storage space of the liquid storage bottle through the air pump, the pressure in the liquid storage space is increased, thereby pushing the liquid to flow out of the liquid storage space. This design avoids the unstable flow rate caused by gravity or manual extrusion, ensuring that the nursing solution can be evenly and continuously delivered to the liquid guiding module, achieving a smooth spraying and application effect.

[0019] The operation of the air pump can be precisely adjusted by the controller, thereby flexibly controlling the air pressure change in the liquid storage space, and then precisely adjusting the output amount of the nursing solution. Whether for the scalp or hair, the spraying intensity and coverage can be adjusted according to needs to ensure that the nursing solution is evenly distributed and achieve the best nursing effect.

[0020] This design uses air pressure to push the nursing solution to flow, avoiding the situation of liquid retention or deposition in the bottle. Especially for viscous or difficult-to-flow liquids, it effectively reduces the possible blockage problems in the liquid guiding module and ensures the long-term stable use of the device.

[0021] The design of the liquid storage bottle adopts a bottle mouth clamping connection, which is convenient for replacement and cleaning. Users can choose different types or brands of nursing solutions according to their needs, flexibly replace the liquid storage bottle, improve the convenience and flexibility of use, and meet diverse nursing needs.

[0022] Through the design of the air pump and the liquid storage module, it is ensured that the liquid storage bottle can maintain good airtightness in the non-use state, avoiding the volatilization or pollution of the nursing solution. At the same time, the independent liquid storage space formed in the inner cavity of the liquid storage bottle also helps to extend the shelf life of the liquid and maintain its active ingredients.

[0023] Further, the bottle mouth connection seat includes a base, the base is provided with the bottle mouth connection cavity, the bottom of the bottle mouth connection cavity is provided with the liquid discharge port and the exhaust pipeline, one end of the exhaust pipeline extends outward toward the outside of the base to form an exhaust inlet, and the other end of the exhaust pipeline extends toward the bottle mouth connection cavity to form an exhaust outlet, the exhaust inlet and the exhaust outlet communicate to form the exhaust port, and the exhaust opening of the air pump communicates with the exhaust inlet.

[0024] By providing the exhaust pipeline, connecting the exhaust opening of the air pump with the exhaust port in the liquid storage bottle, the gas can smoothly enter the interior of the liquid storage bottle through the exhaust pipeline. Such a design not only effectively improves the efficiency of the gas entering the liquid storage space, but also ensures that the air pressure in the liquid storage space can quickly reach the ideal state, thereby more efficiently promoting the flow of the nursing solution and ensuring the stable output of the nursing solution during the spraying and smearing processes.

[0025] The setting of the exhaust pipeline 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 channel. This design further improves the operation stability of the equipment and reduces the failures and maintenance problems that may be caused by the mixing of gas and liquid.

[0026] The exhaust inlet and the exhaust outlet of the exhaust pipeline extend in different directions respectively, which can better guide the air flow into a specific position in 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, ensure the stability of the air pressure, and thus accurately adjust the output volume and spraying effect of the nursing solution.

[0027] The bottle mouth connection seat adopts a base structure, integrating the bottle mouth connection cavity, the liquid discharge port and the exhaust pipeline. The overall design is compact and easy to assemble and disassemble.

[0028] Further, the bottle mouth connection seat further includes an elastic pad, the elastic pad is placed in the bottle mouth connection cavity, and the elastic pad on the side wall of the bottle mouth connection cavity is provided with a threaded inner wall;

[0029] The elastic pad on the bottom wall of the bottle mouth connection cavity is provided with a diversion port corresponding to the position of the liquid discharge port, and the diversion port communicates with the liquid discharge port;

[0030] An elastic pad located at the bottom wall of the nozzle connection cavity has 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.

[0031] The elastic pad provided inside the nozzle connection seat is closely fitted 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 leakage of the nursing solution during use. At the same time, the softness of the elastic pad makes the connection of the nozzle more firm, and it can still maintain a good sealing effect even under long-term use or external force.

[0032] The elastic pad is designed with a thread structure 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.

[0033] The thread of the liquid storage bottle nozzle and the thread 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.

[0034] The elastic pad is designed with a thread structure and made of an elastic material, which simplifies the production process, reduces the manufacturing cost, and can also ensure efficient sealing and fixing effects.

[0035] The thread 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 user experience.

[0036] The nozzle is engaged with the elastic pad thread to further lock the position of the liquid storage bottle, avoiding loosening caused by vibration or extrusion during use, and ensuring the structural stability and service life of the device.

[0037] Furthermore, a one-way valve for preventing liquid from entering the air pump through the exhaust port is also provided between the exhaust opening and the exhaust port of the air pump.

[0038] The setting of the one-way valve effectively prevents the nursing solution 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 gets 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.

[0039] 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 fluctuation when the air pump stops working. This design makes the air pressure in the liquid storage bottle more stable, and the nursing solution can be output more evenly and continuously, improving the coating effect and user experience.

[0040] Liquid entering the air pump may cause short circuits, motor damage or other failures, especially after long-term or multiple uses. The addition of a check valve improves the safety of the device, prevents equipment failures caused by liquid backflow, and reduces maintenance costs and usage risks.

[0041] During use, users do not need to worry about air pump damage and liquid supply interruption caused by liquid backflow, which improves the stability of the product and user trust in the device. The good anti-backflow design enables users to perform hair care more easily and enhances the overall user experience.

[0042] Furthermore, it also includes a hollow top cover. The head of the nozzle connection seat exposes the top of the housing. The head of the nozzle connection seat is provided with the nozzle connection cavity. The hollow top cover is detachably arranged on the top of the housing, and the inner cavity of the hollow top cover forms a liquid storage bottle accommodating cavity.

[0043] The hollow top cover design allows the liquid storage bottle to be easily placed in the inner cavity of the housing and quickly replaced in a detachable manner. Users only need to open the top cover to replace or replenish the care liquid / medicine liquid, and the operation is simple, improving the convenience of use.

[0044] After the hollow top cover is combined with the housing, it not only protects the liquid storage bottle from external environmental pollution, but also enhances the overall sealing performance of the device, prevents the care liquid / medicine liquid from leaking, and ensures safety and hygiene during use.

[0045] The inner cavity of the top cover forms a liquid storage bottle accommodating cavity. Through reasonable space design, the volume of the overall device is saved, making the device more compact and portable, suitable for daily use and carrying.

[0046] The detachable top cover design is convenient for cleaning and maintenance. After long-term use, users can easily clean the liquid storage bottle accommodating cavity, reduce pollution problems caused by residual care liquid / medicine liquid, and thus extend the service life of the device.

[0047] Furthermore, it also includes a plugging device. The plugging device is arranged in the housing. The plugging device includes an elastic plugging seat. The elastic plugging seat is provided with an upper plugging interface and a lower plugging interface. The upper plugging interface and the lower plugging interface are connected. The upper plugging interface is connected to the liquid discharge port. The liquid guiding inlet of the liquid guiding module is connected to the lower plugging interface.

[0048] The design of the elastic plugging seat enables the liquid guiding module to be quickly inserted and connected through the lower plugging interface. The plugging operation is simple and fast. Users can easily install and replace components, improving the practicality of the device.

[0049] The high elasticity design of the elastic socket enables the liquid guide module to swing elastically with the operating force when the care liquid is discharged, thereby achieving a gentle massage of the scalp, increasing comfort, helping to promote blood circulation, and enhancing the care effect.

[0050] During the working process, the medicine applicator has the functions of care and massage at the same time, which brings dual effects to users, improves the user experience and increases the market appeal of the product.

[0051] Furthermore, the controller is provided with a function switch, and 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 and stop and / or speed regulation of the air pump.

[0052] The controller is linked to the elastic socket through the function switch. The movement of the elastic socket can trigger the function switch to realize automatic start and stop and speed regulation of the air pump, making the equipment more intelligent, easy to operate and providing a good user experience.

[0053] Furthermore, the liquid guiding module is built with a liquid separation cavity, the top of the liquid guiding module is provided with the liquid guiding inlet, the bottom of the liquid guiding module is spaced apart with a hollow liquid guiding column, the hollow liquid guiding column is provided with the liquid guiding outlet, and the liquid guiding inlet, the liquid separation cavity and the hollow liquid guiding column are connected;

[0054] The bottom wall of the liquid separation cavity is separated by a liquid guide opening connected to the hollow liquid guide column, and a tapered portion is provided on the bottom wall of the liquid separation cavity between the liquid guide openings, the tip of the tapered portion faces the liquid guide inlet, and a first liquid flow channel is separated by a side wall of the tapered portion, and a second liquid flow channel is provided between the liquid guide opening and the tapered portion, one end of the second liquid flow channel is connected to the liquid guide opening, and the other end of the second liquid flow channel is connected to the first liquid flow channel.

[0055] The conical part and liquid flow channel arranged in the liquid separation cavity make the liquid evenly distributed before being discharged. Through the combined action of the first liquid flow channel and the second liquid flow channel, the liquid flows to multiple liquid outlets to achieve even distribution, avoid the problem of liquid concentration in a certain position or uneven discharge, ensure the even application of liquid during each care process, and improve the care effect.

[0056] The design of the conical part naturally guides the liquid to the liquid guide opening at the bottom of the liquid separation chamber, reducing the possibility of liquid accumulation or retention in the chamber. At the same time, the setting of multiple liquid flow channels provides multiple flow paths for the liquid, ensuring smooth liquid discharge even when some channels are blocked, reducing the risk of blockage during the liquid guide process.

[0057] The tip of the tapered portion faces the liquid guide inlet, and combined with the first liquid flow channel on the side wall and the second liquid flow channel between the liquid guide opening, the liquid is reasonably diverted and guided during the flow process, which reduces the resistance to liquid flow, improves the liquid guide efficiency, and achieves fast and smooth liquid output.

[0058] Through the structural design within the liquid separation cavity, the liquid guiding module can precisely control the amount of liquid output at each liquid guiding outlet, avoiding the situation of excessive or insufficient liquid. This precise control ensures the appropriate release of liquid during the nursing process, enhances the user experience, and avoids unnecessary liquid waste.

[0059] The design of the conical part and the flow channel enables the liquid guiding module to handle liquids with different viscosities. Whether it is relatively thin hair care liquid or relatively viscous essential oil, through reasonable distribution and derivation, good liquid guiding effect can be achieved. This design enhances the applicability and versatility of the device.

[0060] The flow channel design inside the liquid guiding module avoids the long-term stagnation of liquid in the cavity, reduces the corrosion and loss of the device interior caused by liquid residue, and extends the service life of the device. At the same time, the reasonable flow channel layout and distribution structure also reduce the maintenance frequency of the device, enhancing the durability and reliability of the device.

[0061] Furthermore, it further includes a battery. The controller is a control circuit board, and the control circuit board is provided with a charging socket and a power switch for supplying power to and cutting off power from the air pump;

[0062] The housing is open at the position corresponding to the charging socket, and a detachable waterproof sealing plug is provided at the opening;

[0063] The housing is provided with a button at the position corresponding to the power switch;

[0064] The battery is arranged inside the housing and supplies power to the controller and the air pump. The detachable waterproof sealing plug can tightly seal the opening of the charging socket when the charging function is not in use, effectively preventing moisture and impurities from entering the interior of the housing, ensuring that the device can still work normally in a humid environment, and extending the device life.

[0065] When charging is required, the waterproof sealing plug can be easily disassembled to expose the charging socket, with simple operation and enhanced user experience; after charging is completed, the sealing plug can be easily installed again to restore the waterproof state of the device.

[0066] The sealing plug is made of waterproof material, with good corrosion resistance and weather resistance, and can maintain a long-term stable sealing effect in various complex environments, thereby protecting the internal circuit and controller and reducing the risk of device failure caused by water ingress.

[0067] Designing the charging socket and the sealing plug inside the housing results in a compact overall structure, which neither affects the appearance of the device nor compromises the functionality and portability of the device, making the product more competitive in the market.

[0068] The beneficial effects of the present utility model are as follows:

[0069] The utility model pressurizes through an air pump, enabling the liquid in the liquid storage bottle to be discharged evenly and stably, avoiding the problems of liquid waste and unevenness in the traditional manual smearing process, and improving the nursing effect and usage efficiency.

[0070] In the utility model, the start, stop and speed regulation of the air pump are controlled by a controller, achieving precise adjustment of the liquid output volume, enabling users to freely adjust the spraying volume of the nursing liquid according to needs, and being particularly more convenient when smearing the scalp and root areas.

[0071] In the utility model, a one-way valve is arranged between the air outlet of the air pump and the exhaust pipe, effectively preventing the liquid from flowing back into the air pump, avoiding the risk of damage to the air pump caused by liquid backflow, and extending the service life of the equipment.

[0072] In the utility model, the bottle nozzle connection seat is provided with an elastic pad, a threaded inner wall and a piercing design, making the installation of the liquid storage bottle more convenient and having good sealing performance, ensuring that the liquid will not leak, and being faster and safer when replacing the liquid storage bottle.

[0073] In the utility model, the liquid distribution cavity and the diversion structure in the liquid guiding module enable the liquid to be evenly distributed at multiple points, ensuring uniform liquid spraying during use and enhancing the nursing effect. Description of the Drawings

[0123] Turn off the device: After use, the user presses the power switch 82 to turn off the entire device.

[0124] When the air pump 3 is started, the working principle of liquid drainage is achieved

[0125] The air pump 3 operates: The air pump 3 extracts air from the outside to generate an air flow. The air flow passes through the exhaust opening of the air pump 3 and enters the liquid storage space of the liquid storage bottle 41 through the exhaust pipe 53.

[0126] 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.

[0127] 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.

[0128] 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 a plurality of liquid guide openings 231 in the liquid guide module 2.

[0129] 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.

[0130] Anti-backflow protection: In order 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.

[0131] Liquid discharge working principle

[0132] After the nursing liquid enters the liquid guide module 2, it first passes through the liquid distribution cavity 23. A plurality of liquid guide openings 231 are provided on the bottom wall of the liquid distribution cavity 23, and the liquid is distributed here.

[0133] The conical part 232 and the first liquid flow channel 233 and the second liquid flow channel 234 therein in the liquid distribution cavity 23 can control the flow rate and flow direction of the liquid to ensure uniform distribution of the nursing liquid.

[0134] The nursing liquid is finally uniformly discharged through the liquid guide outlet 22 of the hollow liquid guide column 24 to achieve the effect of nursing the scalp.

[0135] In other embodiments, the liquid storage module 4 is provided with a liquid storage space, the liquid storage space is provided with a liquid discharge port 511 and an exhaust port 512, and the height of the exhaust port 512 is higher than the height of the liquid discharge port 511. In this solution, there is no need for the liquid storage bottle 41, and the user needs to add the nursing liquid to the liquid storage space by himself.

[0136] In other embodiments, the liquid storage module 4 is provided with a liquid storage space, the liquid storage space is provided with a liquid discharge port 511 and an exhaust port 512, the height of the exhaust port 512 is higher than the height of the liquid discharge port 511, and the liquid storage module 4 is provided with a bottle mouth connection cavity 51 corresponding to the position of the liquid storage space, and the bottle mouth connection cavity 51 is communicated with the liquid storage space. In this solution, the user can either add the nursing liquid to the liquid storage space by himself or use the method of clamping the liquid storage bottle 41 to the bottle mouth connection cavity 51 to quickly replace the nursing liquid.

[0137] In other embodiments, a comb using a pneumatic liquid pushing device further includes a comb body, which includes a handle portion and a comb tooth portion. The air pump 3, the liquid storage module 4, the controller 8 and the battery 9 are disposed within the comb body. The battery 9 supplies power to the controller 8 and the air pump 3.
