[0025] 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.

[0026] It should be noted that when a component is referred to as being "mounted on," "fixed to," or "set on" another component, it can be directly on the other component or may have an intervening component present. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or may have an intervening component present.

[0027] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of this utility model are only relative concepts or are based on the normal use state of the product, and should not be considered as restrictive.

[0028] The medication application device provided by this utility model can be used to apply medication to affected areas such as skin and hair. It is mainly used to complete the care of small areas of medication application, such as local skin care or medication application on the body, and medication application for hair growth care in local areas of the scalp.

[0029] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The present invention provides a medicine application device, including a cover 1 connected to a medicine storage bottle 200 and a medicine storage chamber 2 for storing medicine during application. The cover 1 has a medicine outlet 11, and the medicine storage chamber 2 is provided with a medicine outlet 3. One end of the cover 1 has an internal thread for screwing into the medicine storage bottle 200. After the medicine in the medicine storage bottle 200 is used up, the medicine storage bottle 200 can be replaced for reuse. It is green and environmentally friendly, and the user purchase cost is low.

[0030] The application device also includes a piston assembly 4 for controlling the on / off state of the dispensing hole 11 and the storage chamber 2. The piston assembly 4 is placed inside the chamber cover 1 and connected to the storage chamber 2. A part of the chamber cover 1 (such as the front end) is located in the storage chamber and can move along the storage chamber 2. For example, the outer wall of the front end of the chamber cover 1 is slidably connected to the inner wall of the storage chamber 2, so that it can slide back and forth along the inner wall of the storage chamber 2.

[0031] When an external force (such as a thrust that moves the cover 1 towards the storage compartment 2) causes the cover 1 to move along the storage compartment 2, the dispensing hole 11 separates from the piston assembly 4, allowing the dispensing hole 11 to communicate with the storage compartment 2 (e.g., Figure 4 (As shown), thus allowing the medicine in the medicine storage bottle 200 to flow through the medicine outlet 11 into the medicine storage chamber 2. When the external force disappears, the piston assembly 4 drives the chamber cover 1 to reset and seal the medicine outlet 11 (as shown). Figure 3 As shown in the diagram, this invention prevents the medicine in the medicine storage bottle 200 from flowing out. The piston assembly 4 connects the cover 1 and the medicine storage chamber 2, preventing excessive separation of the cover 1 and the medicine storage chamber. It also controls the opening and closing of the dispensing hole 11 when the cover 1 moves under pressure or resets under pressure, making operation simple. After the medicine (not limited to medicine, but also including care solutions, skin lotions, or skin creams, etc.) is placed in the medicine storage chamber 2, it is then applied to the area requiring care via the dispensing component 3. This invention eliminates the need for a pump when dispensing medicine and features a simple structure for easy installation, convenient operation, and portability.

[0032] In this embodiment, the medicine storage chamber 2 can be a quantitative medicine storage chamber to ensure that the amount applied each time is consistent. Alternatively, a viewing window can be provided at the medicine storage chamber 2, with scales set at the viewing window to help users control the amount applied more accurately.

[0033] In one specific embodiment, during the liquid dispensing operation, the application device can be inverted, and then pressing the medicine storage bottle 200 will cause the cover 1 to move along the medicine storage chamber 2, separating the dispensing hole 11 from the piston assembly 4, thereby connecting the dispensing hole 11 with the medicine storage chamber 4. At this time, the liquid dispensing channel is opened, and the liquid in the medicine storage bottle 200 can flow out by gravity. This operation is more convenient compared to existing dispensing methods such as pumping, lifting the medicine storage chamber, and twisting the medicine storage chamber. Moreover, the inverted dispensing method helps to completely drain the liquid in the medicine storage bottle 200, avoiding waste of medicine.

[0034] Preferably, the medication application device is also used to puncture the sealing film 201 (the sealing film 201 that comes with the medication bottle 200) on the medication bottle 200 with a puncture cap 5. The puncture cap 5 is disposed in the compartment cover 1 and is close to the connecting end of the compartment cover 1. When the medication bottle 200 is connected to the compartment cover 1, the puncture cap 5 can puncture the sealing film 201 on the medication bottle 200 during the connection process (such as screw connection). As the screwing angle of the medication bottle 200 increases, the puncture hole on the sealing film 201 also increases, allowing the medicine in the medication bottle 200 to flow out smoothly. This utility model facilitates user use through the puncture cap 5, eliminating the need for users to find additional tools to tear open the sealing film 201. Users can directly connect the medication bottle 200 to the compartment cover 1, achieving both connection and puncturing the sealing film 201. The operation is simple and quick, improving ease of use and accelerating the preparation and use of medicines.

[0035] Moreover, placing the puncture cap 5 inside the compartment cover 1 can prevent the puncture cap 5 from being exposed and accidentally injuring the user, and it is also easier to puncture the sealing film 201 (there is no need to align the puncture cap 5 with the sealing film 201; the sealing film 201 can be punctured and torn open during the screwing process between the medicine bottle 200 and the compartment cover 1).

[0036] The puncture cap 5 is provided with a sealing element 6 for sealing the gap between the mouth of the medicine storage bottle 200 and the puncture cap 5, so as to prevent the medicine from leaking from the mouth of the medicine storage bottle 200.

[0037] Please continue reading. Figures 1 to 4 The piston assembly 4 includes a piston body 41 and a spring 42. The piston body 41 is fixedly connected to the drug storage chamber 2 by a flat-head screw 43. The two ends of the spring 42 abut against the piston body 41 and the puncture cap 5, respectively. Specifically, both the piston body 41 and the puncture cap 5 have a positioning part 51 for the positioning spring 42, so that the spring 42 will not deform or shift laterally when compressed, thus ensuring the spring 42's restoring ability and extending its service life.

[0038] In the initial state (e.g.) Figure 3 As shown), spring 42 abuts against piston body 41 and puncture cap 5. Since cap 1 and puncture cap 5 are connected, and medicine bottle 200 is screwed to cap 1, when the application device is inverted, pressing medicine bottle 200 will cause cap 1 to move down synchronously, thereby separating medicine outlet 11 from piston body 41 (piston fixed), so that medicine bottle 200 is connected to medicine storage chamber 2, allowing medicine in medicine bottle 200 to flow into medicine storage chamber 2 (e.g., ...). Figure 4 (As shown). Once the amount of medicine in the medicine storage compartment 2 has been reached, release the medicine storage bottle 200. The spring 42 will reset, causing the compartment cover 1 and the medicine storage bottle 200 to reset synchronously, making the operation convenient.

[0039] Please refer to the following: Figure 5 The opening of the medicine outlet 11 is conical, and one end of the piston body 41 has a conical part that matches the opening of the medicine outlet 11. Through the cooperation of the conical shape and the conical part, the piston body 41 can be smoothly inserted into the medicine outlet 11 during the resetting process of the cover 1, so as to achieve a sealing effect and prevent leakage.

[0040] Furthermore, at least three limiting protrusions 12 are provided at the drug outlet 11 to prevent the cover 1 from swinging during the reset process, and to more accurately insert the piston body 41 into the drug outlet 11.

[0041] The outer wall of the cover 1 has at least one guide protrusion 13. The inner wall of the medicine storage chamber 2 and the groove 21 of the guide protrusion 13 are connected. The guide protrusion 13 moves within the groove 21, which assists in the lifting and lowering of the cover 1, preventing the cover 1 from jamming or swaying during lifting and lowering. This improves the stability and smoothness of the lifting and lowering of the cover 1, making the medicine application device more reliable in actual use. Furthermore, the length of the groove 21 can be set to limit the movement position of the cover 1, thereby achieving the rated capacity of the medicine storage chamber 2.

[0042] A sealing ring 14 is provided on one end of the cover 1 inside the medicine storage chamber 2. The sealing ring 14 is used to seal the gap between one end of the cover 1 and the medicine storage chamber 2 to prevent leakage from the cover 1 between the medicine storage chamber 2.

[0043] Please refer to the following: Figure 6 The drug storage chamber 2 has a mounting post 22 for connecting the piston body 41. The piston body 41 is fixed to the mounting post 22 by a flat-head screw 43 to ensure the position and stability of the piston body 41 in the drug storage chamber 2.

[0044] Furthermore, the medicine storage chamber 2 is equipped with a venting column 23, which is located below the medicine dispensing part 3 of the medicine storage chamber 2. The main function of the venting column 23 is to balance the air pressure inside the medicine storage chamber 2, ensuring that the medicine can flow smoothly into the medicine storage chamber 2, avoiding poor medicine flow caused by air pressure imbalance, thereby reducing medicine waste.

[0045] Preferably, the vent column 23 extends into the medicine storage chamber 2, and its height is lower than that of the mounting column 22, to prevent the chamber cover 1 from being unable to move down (i.e., move towards the medicine storage chamber 2) if the height of the vent column 23 is higher than that of the mounting column 22. Specifically, the height of the vent column 23 can serve as a limiting element for the quantitative medicine storage chamber 2. When the chamber cover 1 is pressed against the vent column 23, the distance between the bottom of the chamber cover 1 and the bottom of the medicine storage chamber 2 is the rated capacity of the medicine storage chamber 2. This allows the user to visually observe whether the medicine storage chamber 2 is full when adding medicine, which helps the user to add medicine accurately and avoid overfilling or underfilling. In addition, the vent column 23 can also protect the spring 42, preventing excessive pressure from affecting its return ability, thereby extending the service life of the spring 42.

[0046] In this embodiment, the dispensing component 3 is a dispensing tooth, a dispensing brush, etc., to facilitate the application of medicine to the scalp. When used for applying medicine to affected skin areas, the dispensing component 3 can be a dispensing brush, a dispensing nozzle, etc., to facilitate the application of medicine to the affected skin area. The structure of the dispensing component 3 is not limited here.

[0047] Please continue reading. Figures 1 to 4 The application device also includes a cylindrical body 7 for easy control of the movement of the lid 1 toward the storage chamber 2. The cylindrical body 7 is connected to the storage chamber 2 and fitted onto the lid 1. During installation, after the storage bottle 200 is connected to the lid 1, the cylindrical body 7 is placed over the storage bottle 200 and the lid 1 and connected to the storage chamber 2. The cylindrical body 7 prevents swaying when pressing the storage bottle 200, reduces the effort required to press the storage bottle 200, improves the aesthetic appearance of the application device, and helps protect the overall integrity of the device and the ease of operation.

[0048] Specifically, the cylindrical body 7 is tubular, and its bottom has a notch 71 for easy hand pressure on the medicine bottle 200, exposing the bottom portion of the medicine bottle 200. The user can press the medicine bottle 200 through the notch 71, similar to using a syringe, making it convenient. Furthermore, the bottom end of the cylindrical body 7 is located on the outer side of the bottom end of the medicine bottle 200. This design prevents accidental pressing of the medicine bottle 200 during storage or transport, thus preventing misoperation. The cylindrical body 7 also has a perforated window 72 for easy observation of the remaining medicine level in the medicine bottle 200.

[0049] The application device also includes a protective cover 8, which covers the outside of the drug storage chamber 2 and serves to protect the drug dispensing component 3 from dust.

[0050] When using the application device, place it upright and screw the medicine storage bottle 200 onto it. After the connection is complete, invert the application device. At this point, simply press the medicine storage bottle 200 to open the dispensing channel, allowing the medicine in the bottle 200 to flow into the storage chamber 2. When pressing the medicine storage bottle 200, the bottle 200, the chamber cover 1, and the puncture cover 5 move downwards simultaneously, while the storage chamber 2, the piston body 41, and the cylinder body 7 remain stationary. When the chamber cover 1 moves downwards, the dispensing hole 11 separates from the piston body 41, thus connecting the medicine storage bottle 200 and the storage chamber 2, allowing the medicine in the bottle 200 to flow into the storage chamber 2. Figure 4 The state shown, Figure 4 The arrows indicate the liquid flow pattern. Once the required volume of medicine is reached in the storage chamber 1, the medicine bottle 200 is released, and the spring 42 resets the bottle, causing the piston body 41 to seal the dispensing port 11. Figure 3 Once the condition is as shown, simply apply the medicine dispenser 3 to the affected area; the operation is very simple.

[0051] In summary, the medication application device provided by this utility model, when in use, involves inverting the device and simply pressing down on the medicine storage bottle to move it downwards. This causes the lid to move along the medicine storage chamber, separating the dispensing hole from the piston assembly, thus connecting the dispensing hole to the medicine storage chamber. This allows the medicine in the storage bottle to flow into the storage chamber through the dispensing hole. When the medicine in the storage chamber reaches the required volume, releasing the storage bottle removes the pressing force, causing the piston assembly to reset and seal the dispensing hole, preventing the medicine in the storage bottle from flowing out. The medicine is then applied to the affected area via the dispensing component. Its operation is extremely simple.

[0052] The aforementioned medication application device also includes a puncture cap for breaking the sealing film on the medication bottle. This puncture cap is located within the storage lid, near the connection end. When the medication bottle is connected to the lid, the puncture cap breaks the sealing film, allowing the medication to flow out smoothly. This puncture cap facilitates user operation, eliminating the need for additional tools to tear open the sealing film. Users can directly connect the medication bottle to the lid, achieving both connection and simultaneous puncture and tearing of the sealing film. This simplifies operation, improves convenience, and accelerates the preparation and use of medications.

[0053] In addition, the application device of this utility model has a simple and compact structure, which greatly reduces its cost and occupies little space. It can be assembled with minoxidil bottles and carried with you, so that users can perform care while on business trips.

[0054] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of the appended claims of this utility model.
