Description

Technical Field

[0001] This utility model relates to the field of medicine application equipment technology, and in particular to a quantitative medicine applicator and its quantitative application device. Background Technology

[0002] In critical industries such as pharmaceuticals, cosmetics, and food processing, precise application of liquids is a fundamental and ubiquitous procedure that plays a vital role in ensuring product quality and performance. The uniformity of the product and its intended effect largely depend on the accuracy of this procedure.

[0003] Existing quantitative application devices, such as the one described in application number CN202121623602.4 (titled "A Quantitative Application Applicator"), draw liquid from a reservoir into a graduated medication chamber by pressing a pump. Since the pump needs to generate sufficient pressure to draw liquid upwards from the bottom of the chamber, the volume of the medication chamber usually needs to be larger than the amount of medication to be applied. This ensures that a sufficient amount of medication is drawn out when the pump is pressed. Users typically operate the device by pumping and observing simultaneously. However, if the user continues to pump after a certain amount of liquid has been pumped into the chamber, it can lead to an overfill of medication and increased pressure, causing liquid to overflow from the dispensing nozzle, wasting medication and potentially contaminating the user's hands, clothing, or the treatment environment. Therefore, there is still room for improvement in this technology. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a quantitative medicine applicator and its quantitative application device, which can ensure that the liquid volume in the temporary storage chamber does not exceed the rated liquid volume, and at the same time balance the pressure in the temporary storage chamber during the liquid addition process.

[0005] To solve the above technical problems, the present invention adopts the following technical solution:

[0006] A quantitative application device includes a body, which is provided with a liquid extraction component for extracting liquid, a temporary storage chamber for quantitatively storing liquid, a reflux component for returning the liquid in the temporary storage chamber, and at least one liquid outlet tooth.

The reflux tube has at least one reflux port, the temporary storage chamber has a reflux orifice, the reflux tube is inserted into the reflux orifice, the reflux orifice seal is used to seal the gap between the reflux orifice and the reflux tube, and the plug is located at the top of the reflux tube. When the body movement control liquid extraction assembly extracts liquid, the reflux orifice seal moves with the body to connect the reflux port with the temporary storage chamber.

[0008] In the quantitative application device, the reflux port is located on the side of one end of the reflux tube, and the other end of the reflux tube has a drain hole.

[0009] In the quantitative application device, the reflux hole seal has a reflux chamber with a conical bottom and a mushroom-shaped plug that is larger at the top and smaller at the bottom, the size of which is adapted to the size of the reflux chamber.

[0010] In the quantitative application device, the liquid extraction component includes a liquid extraction pump and a liquid outlet. The liquid outlet abuts against the liquid outlet end of the liquid extraction pump. The liquid outlet is integrally formed with the machine body, and a liquid outlet is provided on one side of the liquid outlet.

[0011] In the quantitative application device, the reflux hole seal has an ear that is fitted onto the liquid outlet.

[0012] In the quantitative application device, the machine body also has a positioning part for fixing the reflux hole seal.

[0013] The quantitative application device further includes an EMS control board, a vibration motor, and a plurality of EMS massage teeth.

[0014] The quantitative application device also includes a bottle mouth connector and a bottle mouth seal for connecting the liquid storage bottle. The bottle mouth connector is slidably connected to the bottom of the machine body, and the bottle mouth seal is disposed on the bottle mouth connector. The other end of the return tube passes through the bottle mouth seal and is exposed outside the bottle mouth connector.

[0015] A quantitative drug delivery device includes a storage bottle and a quantitative application device as described in any of the above claims, wherein the storage bottle and the quantitative application device are detachably connected.

[0016] Compared to existing technologies, the quantitative drug applicator and its quantitative application device provided by this utility model, wherein the quantitative application device draws liquid into the temporary storage chamber through the liquid extraction component, while the reflux component simultaneously refluxes excess liquid (such as refluxing it into the storage bottle below), ensuring that the liquid volume and pressure in the temporary storage chamber are always constant, achieving precise quantitative control, avoiding the phenomenon of excessive liquid in the temporary storage chamber causing excessive pressure and resulting in liquid spraying or leakage from the dispensing teeth, and also avoiding the impact of insufficient pumped liquid on the treatment or nursing effect, thus improving the accuracy and consistency of the liquid application effect.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The quantitative application device provided by this utility model is mainly used for applying hair care liquid or medicine. It can adapt to liquids of different viscousities. The excess liquid in the temporary storage chamber is returned to the bottle through the reflux component, so that the temporary storage chamber maintains a fixed amount of liquid and maintains the pressure balance of the temporary storage chamber, thereby achieving the purpose of quantitative application.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The quantitative application device 100 provided by this utility model includes a body 1, on which a liquid extraction component 2 for extracting liquid, a temporary storage chamber 3 for quantitatively storing liquid, a return component 4 for returning the liquid in the temporary storage chamber 3, and at least one liquid outlet tooth 5 are provided. The liquid outlet end of the liquid extraction component 2 and the liquid outlet tooth 5 are connected to the temporary storage chamber 3. When the liquid extraction component 2 extracts liquid into the temporary storage chamber 3, the return component 4 can return excess liquid (e.g., return it to the storage bottle 200) to maintain a predetermined amount of liquid in the temporary storage chamber 3, avoiding the phenomenon of excessive liquid in the temporary storage chamber 3 causing excessive pressure and resulting in liquid spraying or leakage from the liquid outlet tooth 5. This utility model can also avoid the phenomenon of poor treatment or nursing effect caused by insufficient liquid in the temporary storage chamber 3 by storing a quantitative amount of liquid (such as minoxidil liquid) in the temporary storage chamber 3.

[0027] In practical use, when the liquid extraction component 2 draws liquid into the temporary storage chamber 3, if the liquid volume in the temporary storage chamber 3 exceeds the predetermined amount, the return component 4 promptly guides the excess liquid back to the storage bottle 200 below the temporary storage chamber 3. This ensures that the liquid volume and pressure in the temporary storage chamber 3 remain constant, achieving precise quantitative control, preventing leakage due to excessive pressure, and improving the accuracy and consistency of liquid application. During operation, the user can pump excess liquid without needing to constantly monitor the pumped volume, bringing convenience to the operation.

[0028] In the quantitative application device 100 of this invention, the reflux assembly 4 plays a crucial role in ensuring that the liquid volume in the temporary storage chamber 3 is maintained at a predetermined level. The reflux assembly 4 mainly includes a reflux pipe 41, a reflux orifice seal 42, and a plug 43. The reflux pipe 41 has at least one reflux port 411, and the temporary storage chamber 3 has a reflux orifice 31. The reflux pipe 41 is inserted into the reflux orifice 31. The reflux orifice seal 42 seals the gap between the reflux orifice 31 and the reflux pipe 41, preventing liquid leakage from the temporary storage chamber 3. The plug 43 is located at the top of the reflux pipe 41 and seals the top of the reflux pipe 41, as well as the gap between the reflux orifice seal 42 and the reflux pipe 41 when no liquid is being drawn (e.g., ...). Figure 3 As shown in the diagram, when the body 1 moves (in this invention, the liquid extraction component can be controlled to extract liquid by pressing the body 1 to move the body downwards), and the liquid extraction component 2 is controlled to extract liquid, the return hole seal 42 moves downwards with the body 1, while the return pipe 41 remains stationary. During the movement, the plug 43 separates from the return hole seal 42, exposing the return port 411 and connecting it with the temporary storage chamber 3. At this time, the return port 411 is exposed (as shown in the diagram). Figure 4(As shown in the diagram). Therefore, each time the liquid extraction component 2 extracts liquid, the return port 411 opens once. When the amount of liquid extracted by the liquid extraction component 2 exceeds the height of the return port 411, during the extraction process, the return port 411 allows the liquid exceeding the height to flow back into the storage bottle 200, and the pressure in the temporary storage chamber 3 will not become excessive due to excessive liquid. Through this design, the return component 4 can not only prevent leakage caused by excessive liquid and excessive pressure in the temporary storage chamber 3, but also ensure the accuracy and consistency of liquid application, improve the functionality and reliability of the entire quantitative application device 100, and enhance the convenience of the liquid extraction operation.

[0029] Please continue reading. Figures 1 to 4 The return port 411 is located on the side of one end of the return pipe 41, and the other end of the return pipe 41 is located on the bottle mouth connector 7 on the lower side of the machine body, and has a drain hole 412. When liquid enters the return pipe 41 from the return port 411, it is discharged through the drain hole 412, ensuring the smooth flow of liquid back and avoiding blockage during the backflow process. The number of return ports 411 can be 2 to 3, which ensures the structural strength of the return pipe 41 and also ensures that the liquid backflow speed at the return port 411 is greater than or equal to the liquid extraction speed of the extraction component 2, thereby preventing excessive liquid in the temporary storage chamber 3.

[0030] The reflux orifice seal 42 has a reflux chamber 421 with a conical bottom to facilitate the smooth flow of excess liquid. The plug 43 is a silicone plug with a mushroom shape, wider at the top and narrower at the bottom. The size of the plug 43 is adapted to the size of the reflux chamber 421. Each time the control body 1 moves downward to control the liquid extraction component 2 to extract liquid, the reflux port 411 opens. After the control body 1 is released, the reflux orifice seal 42 synchronously resets and seals the reflux port 411. The liquid in the reflux chamber 421 can be squeezed into the reflux port 411 through the plug 43. After the control body 1 moves downward to extract liquid multiple times, excess liquid may be pumped into the temporary storage chamber 3. However, each time the liquid extraction component 2 works, the reflux port 411 will open in time to allow the excess liquid to flow back to the storage bottle 200, thereby achieving the function of quantitative liquid extraction. When the liquid has a high viscosity, the liquid return speed in the return chamber 421 may be less than the liquid extraction speed. The plug 43 can squeeze the liquid in the return chamber 421 into the return port 411 and discharge it. This can prevent the liquid in the return chamber 421 from flowing into the temporary storage chamber 3 when the metering applicator 100 is turned upside down for applicating, and ensure that the liquid volume in the temporary storage chamber 3 remains constant. Through the cooperation between the plug 43 and the return chamber 421, this invention can adapt to liquids in various states and ensure adaptability and accuracy when using liquids of different viscosities.

[0031] like Figures 2 to 5As shown, the liquid extraction assembly 2 includes a liquid extraction pump 21 and a liquid outlet 22. The liquid outlet 22 abuts against the liquid outlet end of the liquid extraction pump 21. The liquid outlet 22 is integrally set with the body 1, which simplifies the structure, reduces assembly steps, and improves the overall stability and reliability.

[0032] The liquid outlet 22 is provided with a liquid outlet 221 (i.e. the liquid outlet end of the liquid extraction component 2) on one side. The liquid outlet 221 is located in the temporary storage chamber 3 and is connected to the temporary storage chamber 3. The liquid extracted by the liquid extraction pump 21 flows out through the liquid outlet 221, so that the liquid is drawn from the liquid storage bottle 200 into the temporary storage chamber 3.

[0033] Specifically, the outlet 221 is positioned away from the return hole seal 42. This ingenious layout reduces interference with the liquid level at the return hole seal 42 during the pumping process. When the pump 21 is operating, the outlet 221 guides the liquid smoothly into the temporary storage chamber 3, avoiding liquid level fluctuations, ensuring a steady rise in the liquid level, and preventing liquid from flowing back from the return hole seal 42 if the liquid level in the temporary storage chamber 3 has not reached the predetermined amount, thereby achieving precise control of the liquid level in the temporary storage chamber 3.

[0034] The liquid outlet 22 extends into the temporary storage chamber 3 to ensure smooth liquid delivery to the temporary storage chamber 3. The return hole seal 42 has an ear 422 fitted onto the liquid outlet 22, which not only seals the gap between the return hole 31 and the return pipe 41 to prevent liquid leakage from the return hole 31, but also seals the connection between the liquid outlet 22 and the body 1 through its ear 422, effectively preventing leakage at the liquid outlet 22. This dual sealing function of the return hole seal 42 makes the structure of the entire device more compact, reduces additional sealing components, and simplifies the installation steps.

[0035] During installation, the tight fit between the temporary storage chamber 3 and the body 1 can compress the reflux hole seal 42, ensuring a more stable installation and preventing the reflux hole seal 42 from shifting or flipping during rising and falling, thus ensuring reliability during long-term use.

[0036] The body 1 also has a positioning part 11 for fixing the reflux hole seal 42, ensuring the stability and sealing performance of the reflux hole seal 42 during operation. By clamping the reflux hole seal 42 with the positioning part 11, deformation or displacement during movement can be prevented, ensuring good sealing and preventing liquid leakage from the reflux chamber 421 along the outer wall of the reflux pipe 41. Specifically, the inner wall of the reflux hole seal 42 is also provided with at least two flanges (not labeled in the figure), enabling the reflux hole seal 42 to both prevent liquid leakage along the outer wall of the reflux pipe 41 and ensure that the reflux hole seal 42 rises or falls smoothly with the body, while the reflux pipe 41 remains stationary.

[0037] In the quantitative application device 100 of this utility model, in addition to a precise liquid delivery and reflux control mechanism, advanced EMS technology is integrated to enhance the application effect and provides an additional massage function, thereby improving the overall user experience. Specifically, the quantitative application device 100 also includes an EMS control board 6, a vibration motor 61, and several EMS massage teeth 60. The EMS control board 6 and the vibration motor 61 are mounted on the body 1 and electrically connected to the EMS massage teeth 60, enabling the EMS massage teeth 60 to control signals to execute the massage function. The quantitative application device 100 also has a built-in battery 62 to provide the necessary power to the EMS control board 6 and the vibration motor 61. The quantitative application device 100 also has a control button 63, which allows the user to control the working status of the EMS massage teeth 60, enabling the massage function to be started, stopped, or otherwise adjusted. The battery 62 and control button 63 mentioned above are prior art and will not be described in detail further.

[0038] The quantitative application device 100 also includes a toothed plate 50, which is detachably connected to the temporary storage chamber 3 for easy cleaning and replacement, preventing residual liquid in the temporary storage chamber 3 from crystallizing and clogging it. The dispensing teeth 5 are disposed on the toothed plate 50, allowing liquid in the temporary storage chamber 3 to be discharged and evenly applied. During cleaning, the toothed plate 50 is removed, at which point the reflux hole seal 42 is in its initial state, sealing the reflux hole 31, preventing contamination of the remaining liquid in the storage bottle 200 during cleaning.

[0039] The EMS massage teeth 60 are arranged around the liquid dispensing teeth 5, allowing the EMS massage teeth 60 to effectively massage and stimulate the target area while the liquid dispensing teeth 5 are applying the liquid, thereby improving the treatment or care effect. This invention not only provides precise liquid control but also enhances the user experience through the EMS massage function. This multi-functional integrated design enables the device to promote liquid absorption and penetration while providing the application effect, offering users a more comfortable and efficient user experience, suitable for various care and treatment occasions.

[0040] The quantitative application device 100 also includes a bottle mouth connector 7 and a bottle mouth seal 8 for connecting the liquid storage bottle 200. The bottle mouth connector 7 is slidably connected to the bottom of the machine body 1. The bottle mouth seal 8 is disposed on the bottle mouth connector 7 and located at the connection between the bottle mouth connector 7 and the liquid storage bottle 200. The lower end (i.e., the other end) of the return pipe 41 passes through the bottle mouth seal 8 and protrudes from the bottle mouth connector, located at the bottle mouth of the liquid storage bottle 200, so that the liquid storage bottle 200 is in a sealed state, preventing the remaining liquid in the liquid storage bottle 200 from being contaminated, and also preventing the liquid in the liquid storage bottle 200 from leaking when the quantitative application device 100 is tilted. When drawing liquid, the machine body 1 moves up and down, while the bottle mouth connector 7 and the return pipe 41 do not move, allowing the liquid in the return pipe 41 to flow smoothly back into the liquid storage bottle 200. Through the connection between the bottle mouth connector 7 and the liquid storage bottle 200, the user can easily replace the liquid storage bottle 200, making the operation simple.

[0041] The quantitative application device 100 also includes a protective cover 9, a bottom cover 70, and a decorative piece 71. The protective cover 9 is placed over the outside of the temporary storage chamber 3 to protect the dispensing teeth 5 and the EMS massage teeth 60, preventing damage or contamination to them. A decorative piece 91 is also provided on the top of the protective cover 9. This decorative piece 91 can be used to display nameplates, patterns, etc., enhancing the product's visual appeal and brand promotion effect.

[0042] The bottom cover 70 is located at the bottom of the bottle neck connector 7, concealing the connection between the bottle neck connector 7 and the liquid storage bottle 200, making the overall appearance of the device after connection with the liquid storage bottle 200 neater and more aesthetically pleasing. The decorative piece 71 is located at the inner bottom of the bottom cover 70, cleverly concealing the screws connecting the bottom cover 70 and the bottle connector, preventing them from being exposed and further enhancing the device's refined appearance. Through these design considerations, the quantitative application device 100 not only functionally meets the need for precise control of liquid application, but also presents a refined and professional appearance, enhancing the product's market competitiveness.

[0043] Based on the aforementioned quantitative application device 100, this utility model also provides a quantitative medicine applicator, including a storage bottle 200 and a quantitative application device 100. The storage bottle 200 and the quantitative application device 100 are detachably connected, allowing users to easily replace the storage bottle 200 or clean the quantitative application device 100 without complicated operations, thus improving ease of use. Since the structure and function of the quantitative application device 100 have already been described in detail above, they will not be repeated here to avoid redundancy.

[0044] In summary, the quantitative medicine applicator and its quantitative application device provided by this utility model, wherein when the quantitative application device draws liquid into the temporary storage chamber through the liquid extraction component, the reflux component can simultaneously return excess liquid to the lower storage bottle, ensuring that the temporary storage chamber maintains a predetermined amount of liquid, thereby ensuring that the temporary storage chamber always maintains a constant liquid volume and pressure, achieving precise quantitative control, and avoiding the phenomenon of excessive liquid in the temporary storage chamber causing excessive pressure in the temporary storage chamber, resulting in liquid spraying or leakage from the dispensing teeth.

[0045] In addition, this utility model has the advantages of simple structure, easy operation, and users can quickly master the use method. It is convenient to use in various environments. Moreover, due to its simple structure, the cleaning and maintenance of the device are also easy, which helps to maintain the long-term use of the equipment.
