Description

Technical Field

[0001] The utility model relates to a nozzle connecting seat structure of a pneumatic liquid pushing device. 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 be greasy, resulting in a poor use experience.

[0004] In existing scalp care devices, usually the user needs to add the care liquid to the liquid storage cavity by himself / herself, the operation is complex, and it is easy to leak liquid when filling the care liquid, resulting in greasy hands or the device. Content of the Utility Model

[0005] The purpose of the utility model is to provide a nozzle connecting seat structure of a pneumatic liquid pushing device that ensures the nozzle is tightly locked in the nozzle connecting cavity and has a low cost.

[0006] The purpose of the utility model is realized as follows:

[0007] A nozzle connecting seat structure of a pneumatic liquid pushing device includes a nozzle connecting seat. The nozzle connecting seat includes a base. The base is provided with a nozzle connecting cavity for connecting a liquid storage bottle. A liquid discharge port and an exhaust pipeline are arranged at the bottom of the nozzle connecting cavity;

[0008] One port of the exhaust pipeline extends towards the outside of the base to form an exhaust inlet, and the other port of the exhaust pipeline extends towards the direction of the nozzle connecting cavity to form an exhaust outlet;

[0009] The height of the liquid discharge port is lower than the height of the exhaust outlet.

[0010] By designing the height of the liquid discharge port to be lower than the height of the exhaust outlet, it is ensured that the gas first enters the inside of the liquid storage bottle, forms air pressure in the bottle, and thus pushes the liquid to be discharged smoothly through the liquid discharge port, avoiding the liquid from flowing back into the exhaust pipeline. This design improves the liquid pushing efficiency and ensures the stability and uniformity of the liquid discharge.

[0011] The exhaust port is located at a higher position, ensuring that the gas generated by the air pump first forms pressure in the liquid storage bottle, enabling the liquid to be smoothly discharged through the liquid discharge port, thereby avoiding uneven liquid pushing or interruption caused by unstable air pressure.

[0012] Since the liquid discharge port is arranged at the bottom of the bottle mouth connection cavity, that is, near the lowest point in the liquid storage bottle, even when the liquid is less, the remaining liquid can be fully utilized, reducing waste.

[0013] The reasonable layout of the liquid discharge port and the exhaust port makes the overall structure compact, and the production and installation of the connection seat are simpler and easier to operate, which helps to improve production efficiency and reduce manufacturing costs.

[0014] The height difference between the liquid discharge port and the exhaust pipe, combined with the sealing design of the bottle mouth connection cavity, can better prevent gas and liquid leakage, ensure good sealing performance of the equipment during operation, and improve the use safety.

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

[0016] 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 located on the side wall of the bottle mouth connection cavity is provided with a threaded inner wall;

[0017] The elastic pad located 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 is communicated with the liquid discharge port;

[0018] The elastic pad located on the bottom wall of the bottle mouth 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 bottle mouth connection cavity.

[0019] The elastic pad arranged in the bottle mouth connection seat is tightly fitted with the bottle mouth through the threaded inner wall, effectively improving the sealing performance between the bottle mouth 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 bottle mouth more firm, and even under long-term use or external force, it can still maintain a good sealing effect.

[0020] The elastic pad is designed with a threaded structure and has elasticity, which can adapt to the bottle mouths of different sizes of liquid storage bottles, making the medicine applicator have wide applicability and being able to flexibly match various specifications of liquid storage bottles on the market.

[0021] The threads of the liquid storage bottle mouth and the threads of the elastic pad are engaged with each other, ensuring that the bottle mouth is tightly locked in the bottle mouth connection cavity, thereby improving the sealing effect, preventing liquid leakage, and ensuring the safety and stability during use.

[0022] The elastic pad is designed with a threaded structure and is made of elastic material, which simplifies the production process, reduces the manufacturing cost, and can also ensure high-efficiency sealing and fixing effects.

[0023] 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 enhancing the user experience.

[0024] The nozzle is in threaded engagement with the elastic pad, further locking the position of the liquid storage bottle and preventing loosening caused by vibration or extrusion during use, ensuring the structural stability and service life of the device.

[0025] Furthermore, the end of the exhaust pipe extending into the nozzle connection cavity is provided with a piercing portion for piercing the nozzle sealing film of the liquid storage bottle.

[0026] In traditional designs, users usually need to manually remove the sealing film of the liquid storage bottle nozzle. This design simplifies the usage process and enhances the user experience by automatically piercing the sealing film with the piercing portion when the liquid storage bottle is installed in place.

[0027] The automatic piercing design avoids potential contamination or leakage caused by users manually removing the sealing film, and reduces the risk of liquid leakage due to improper installation after the sealing film is removed, thereby improving the sealing performance and safety of the device.

[0028] The piercing portion is directly connected to the exhaust pipe. After piercing the sealing film, gas can quickly enter the interior of the liquid storage bottle, forming a stable air pressure to push the liquid out, ensuring the efficient operation of the pneumatic liquid pushing device.

[0029] The piercing portion is designed as part of the exhaust pipe, reducing the use of additional mechanical structures, thereby reducing the probability of component wear and extending the service life of the device.

[0030] Integrating the piercing function into the end of the exhaust pipe eliminates the need for an additional dedicated piercing device, simplifies the product structure design, reduces production costs, and improves manufacturing efficiency.

[0031] Furthermore, the end face of the exhaust pipe extending into the nozzle connection cavity is an inclined plane, and the end of the inclined plane forms the piercing portion. Further, a diversion port is provided at the lowest point of the elastic pad located on the bottom wall of the nozzle connection cavity, and the elastic pad located on the bottom wall of the nozzle connection cavity is provided with an inclined plane inclined towards the diversion port.

[0032] The inclined design of the elastic pad enables the liquid in the liquid storage bottle to naturally flow towards the diversion port, reducing the liquid residue at the bottom of the bottle, improving the utilization rate of the liquid, and ensuring that the liquid can be fully discharged.

[0033] Through the coordinated design of the inclined plane and the diversion port, the liquid can flow smoothly into the diversion port. Even when the liquid volume in the liquid storage bottle is small, it can be discharged concentratedly, reducing the waste of the remaining liquid and improving the resource utilization efficiency.

[0034] The inclined plane design can guide the liquid flow, avoid the accumulation and irregular flow of the liquid at the bottom of the connection cavity, ensure the stability and uniformity of the liquid discharge, and improve the use effect of the device.

[0035] In addition to guiding the liquid, the elastic pad also has good sealing and buffering functions. It can provide a better sealing effect when connecting the liquid storage bottle, prevent liquid leakage, and at the same time reduce the impact of the bottle body on the connection cavity, extending the service life of the device.

[0036] Due to the guiding effect of the inclined plane, even relatively viscous liquids can be smoothly introduced into the diversion port, avoiding blockage, improving the applicability of the device, and enabling it to handle liquids with various viscosities.

[0037] The beneficial effects of the present utility model are as follows:

[0038] In the present utility model, by designing the height of the liquid discharge port to be lower than the height of the exhaust outlet, it is ensured that the gas first enters the interior of the liquid storage bottle, forms air pressure inside the bottle, and thus pushes the liquid to be discharged smoothly through the liquid discharge port, avoiding the liquid from flowing back into the exhaust pipeline. This design improves the liquid pushing efficiency and ensures the stability and uniformity of the liquid discharge.

[0039] In the present utility model, the exhaust port is located at a higher position, ensuring that the gas generated by the air pump first forms pressure inside the liquid storage bottle, enabling the liquid to be discharged smoothly through the liquid discharge port, and thus avoiding the uneven liquid pushing or interruption phenomenon caused by unstable air pressure.

[0040] In the present utility model, since the liquid discharge port is arranged at the bottom of the bottle mouth connection cavity, that is, near the lowest point inside the liquid storage bottle, even when the liquid is less, the remaining liquid can be fully utilized, reducing waste.

[0041] In the present utility model, the elastic pad arranged inside the bottle mouth connection seat is tightly fitted with the bottle mouth through the inner wall of the thread, effectively improving the sealing performance between the bottle mouth and the connection cavity, preventing the leakage of the nursing liquid during use. At the same time, the softness of the elastic pad makes the connection of the bottle mouth more firm, and it can still maintain a good sealing effect even under long-term use or external force.

[0042] In the present utility model, through the automatic piercing design, it avoids the possible contamination or leakage caused by the user manually removing the sealing film, and at the same time reduces the risk of liquid leakage caused by incorrect installation after the sealing film is removed, thus improving the sealing performance and safety of the device.

[0043] In this utility model, the inclined design of the elastic pad enables the liquid in the liquid storage bottle to flow naturally towards the diversion port, reducing the residue of the liquid at the bottom of the bottle, improving the utilization rate of the liquid, and ensuring that the liquid can be fully discharged.

[0082] How the user replaces the liquid storage bottle 41

[0083] Remove the hollow top cover 6: First, the user removes the hollow top cover 6 from the top of the housing 1.

[0084] 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.

[0085] 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 sealing.

[0086] Install the hollow top cover 6: Reinstall the hollow top cover 6 on the top of the housing 1 to complete the replacement.

[0087] The process of the user starting the air pump 3 for liquid discharge can be achieved through the following steps:

[0088] Install the liquid storage bottle 41: First, install the liquid storage bottle 41 filled with the nursing liquid in the pneumatic medicine applicator, ensure that the nozzle is tightly clamped in the nozzle connection cavity 51, and make the sealing film of the nozzle be pierced by the piercing portion 55 of the exhaust pipeline 53 to ensure that the liquid can flow smoothly into the liquid discharge port 511.

[0089] Turn on the device: The user presses the power switch 82 outside the housing 1 to connect the power supply of the air pump 3.

[0090] 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 socket 7 to touch or move away from the function switch 81, controlling the start and stop of the air pump 3.

[0091] The air pump 3 works to generate air pressure: After the air pump 3 is started, it extracts air from the outside, and the air flow enters the liquid storage space in the liquid storage bottle 41 through the exhaust pipe 53. As the air pressure in the liquid storage space increases, the liquid is pressed and flows into the liquid guiding module 2 through the liquid discharge port 511.

[0092] The liquid is discharged and applied: The nursing liquid is discharged through the liquid discharge outlet 22 of the liquid guiding module 2. The user can adjust the working speed or start / stop of the air pump 3 according to needs, thereby controlling the amount of sprayed liquid and the spraying range, and achieving the effect of evenly applying the nursing liquid.

[0093] Turn off the device: After use, the user presses the power switch 82 to turn off the entire device.

[0094] When the air pump 3 is started, the working principle of liquid discharge is realized

[0095] The air pump 3 works: 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.

[0096] 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 will form a pressure difference higher than the outside in the liquid storage space.

[0097] 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 nozzle 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 inlet 21 of the liquid guiding module 2.

[0098] The liquid guiding module 2 distributes the liquid: After the nursing liquid enters the liquid guiding 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 discharge openings 231 in the liquid guiding module 2.

[0099] The liquid is ejected: The nursing liquid is discharged through the hollow liquid guiding column 24 and the liquid discharge 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.

[0100] Anti-backflow protection: In order to prevent the liquid from flowing back into the air pump 3, a one-way valve is set 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.

[0101] Liquid discharge working principle

[0102] After the nursing liquid enters the liquid guiding module 2, it first passes through the liquid distribution cavity 23. A plurality of liquid guiding openings 231 are provided on the bottom wall of the liquid distribution cavity 23, and the liquid is distributed here.

[0103] The conical part 232 in the liquid distribution cavity 23, the first liquid flow channel 233 and the second liquid flow channel 234 therebetween can control the flow rate and flow direction of the liquid, ensuring uniform distribution of the nursing liquid.

[0104] Finally, the nursing liquid is evenly discharged through the liquid guiding outlet 22 of the hollow liquid guiding column 24, achieving the effect of nursing the scalp.

[0105] 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 that of the liquid discharge port 511. In this solution, there is no need for a liquid storage bottle 41, and the user needs to add the nursing liquid to the liquid storage space by himself.

[0106] 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 that of the liquid discharge port 511. A nozzle connection cavity 51 is provided corresponding to the position of the liquid storage space of the liquid storage module 4, and the nozzle 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 insert the liquid storage bottle 41 into the nozzle connection cavity 51 to quickly replace the nursing liquid.

[0107] In other embodiments, a comb with a pneumatic liquid pushing device further includes a comb body, the comb body includes a handle part and a comb tooth part, the air pump 3, the liquid storage module 4, the controller 8 and the battery 9 are arranged in the comb body, the battery 9 supplies power to the controller 8 and the air pump 3, a liquid guiding module 2 installation cavity is formed in the comb tooth part, the liquid guiding module 2 is detachably arranged in the liquid guiding module 2 installation cavity, and the liquid guiding inlet 21 of the liquid guiding module 2 is communicated with the liquid discharge port 511.
