When the medicine in the medicine bottle 200 is used up, the medicine bottle 200 can be replaced and used again for quantitative liquid dispensing, which is green and environmentally friendly, and the user purchase cost is low.

[0036] Please also read Figures 3 to 9 The liquid outlet and storage part 20 is provided with a medicine chamber 21, and the liquid outlet and storage part 20 is provided with a medicine applying part 30 for applying liquid. The medicine chamber 21 temporarily stores the liquid flowing out of the medicine bottle 200, and then applies it to the skin through the medicine applying part 30.

[0037] Among them, the liquid outlet and storage part 20 is a transparent or translucent liquid outlet and storage part, so that the amount of liquid in the medicine chamber 21 can be clearly seen, so that the user can clearly know the amount of liquid injected when adding liquid, and the remaining liquid in the medicine chamber 21 when in use.

[0038] Of course, the liquid outlet storage member 20 may also be an opaque liquid outlet storage member, and an observation window (not shown in the figure) is provided on the liquid outlet storage member 20, and a scale is provided at the observation window, so that the user can intuitively see the outflow of liquid and the remaining amount used, thereby achieving the function of quantitative application, and can be used for the care of different types of liquids, such as essential oils, hair growth liquid, skin care lotion, hair care liquid, etc.

[0039] Optionally, the medicine applying piece 30 is flat, and may adopt a bristle brush head, a silicone brush head, a sponge brush head, a breathable membrane, a mesh cloth and / or liquid outlet teeth, etc. In this embodiment, a bristle brush head is preferred, which has a good feel when applying medicine, and can be well used for applying medicine on local skin (such as hairline, hairline, etc.). When applying medicine, it is only necessary to brush the medicine liquid on the scalp at the hairline, which is easy to operate and clean, and prevents crystallization and dust accumulation of the medicine applying piece 30 after use.

[0040] Please continue reading Figures 1 to 3 One end of the liquid outlet and storage component 20 is provided with a blind groove 22 for mounting the upper medicine component 30, and the blind groove 22 for mounting the upper medicine component 30 is provided with at least one liquid outlet (not shown in the figure) for connecting the blind groove 22 for mounting the upper medicine component 30 with the medicine chamber 21, so that the medicine liquid in the medicine chamber 21 can infiltrate the upper medicine component 30.

[0041] Furthermore, there are two liquid outlets, which can be located at both ends of the blind groove 22 for installing the upper medicine piece 30, so that the medicine liquid in the medicine chamber 21 can quickly infiltrate the upper medicine piece 30 without causing the medicine liquid to drip.

[0042] Optionally, the sum of the lengths of the liquid outlets is smaller than the width of the blind groove 22 for installing the upper medicine piece 30, so that the liquid outlet speed during application meets the application requirements, and when the upper medicine piece 30 leaves the application site, liquid will not drip and cause waste.

[0043] Please continue reading Figures 1 to 6 The smearable medicine applicator 100 of the utility model also includes a bottle mouth seal 40. The main function of the bottle mouth seal 40 is to cooperate with the liquid outlet and storage component 20 as a liquid outlet switch, so that the liquid in the medicine bottle 200 can flow into the medicine chamber 21.

[0044] Optionally, the bottle mouth seal 40 is provided with a liquid outlet 41, and the liquid outlet storage component 20 is connected to the bottle mouth seal 40, so that the liquid outlet storage component 20 and the bottle mouth seal 40 are a whole and can rotate relative to the bottle mouth connector 10 at the same time, and determine whether to open the liquid outlet channel 11 by rotating a certain angle.

[0045] In the initial state, the bottle mouth connector 10 blocks the liquid outlet 41, so that the medicine chamber 21 is isolated from the bottle mouth connection hole 12. Fig. 9 and 10When the liquid outlet and storage member 20 rotates relative to the bottle mouth connector 10 at a preset angle, the liquid outlet hole 41 of the bottle mouth sealing member 40 communicates with the liquid outlet channel 11 of the bottle mouth connector 10. Figure 7 and 8 state, so that the medicine chamber 21 is connected with the bottle mouth connecting hole 12, and the liquid in the medicine bottle 200 can flow into the medicine chamber 21.

[0046] In this embodiment, the medicine upper part 30 is located at one end of the liquid outlet and storage part 20 and is connected to the liquid outlet of the medicine chamber 21, so that the liquid in the medicine chamber 21 flows out from the liquid outlet to infiltrate the medicine upper part 30, and is applied to the part that needs care through the medicine upper part 30.

[0047] Please continue reading Figures 1 to 10 The liquid outlet and storage component 20 is connected to the bottle mouth sealing component 40 by a screw 50. When rotating, the liquid outlet and storage component 20 and the bottle mouth sealing component 40 are relatively fixed, that is, the two rotate together.

[0048] Furthermore, a groove 24 is provided at the other end of the liquid outlet and storage component 20, and a sealing ring 25 is provided in the groove 24 to seal the liquid outlet and storage component 20 and the bottle mouth connector 10 to prevent liquid from leaking from the gap between the liquid outlet and storage component 20 and the bottle mouth connector 10 when liquid is discharged.

[0049] Please also read Figures 1 to 10 In the smearable medicine applicator 100 of the utility model, the bottle mouth seal 40 is provided with a limiter 42 for controlling the rotation angle of the liquid outlet storage member 20, and the bottle mouth connector 10 is provided with a liquid outlet shielding member 13, the gap between which and the side wall of the bottle mouth seal 40 is less than 0.3 mm, and the gap sealing principle can be used to prevent leakage. Gap sealing is a sealing form that uses the tiny gap between the liquid outlet shielding member 13 and the bottle mouth seal 40 to achieve sealing, which mainly relies on the fluid resistance effect in the sealing gap and achieves the purpose of preventing leakage through the viscous friction of the fluid.

[0050] Specifically, the liquid outlet shielding member 13 has a notch 131 for accommodating and avoiding the limiting member 42 , and the width of the limiting member 42 is smaller than the width of the notch 131 , so that the bottle mouth connector 10 can rotate freely within a preset angle.

[0051] Optionally, a blocking portion 132 cooperating with the limiting member 42 is provided on the liquid outlet shielding member 13 at one side of the notch 131, and the blocking portion 132 is provided to limit the range of a preset angle. For example, a blocking portion 132 is provided at one end of a liquid outlet shielding member 13, and a blocking portion 132 is provided at the other end of the other liquid outlet shielding member 13, so that the liquid outlet storage member 20 stops rotating when the limiting member 42 abuts against the blocking portion 132.

[0052] In this embodiment, the preset angle is 10 degrees to 350 degrees, that is, the liquid in the medicine bottle 200 can flow out from the liquid outlet channel 11 when the liquid outlet and storage member 20 rotates 10 degrees to 350 degrees.

[0053] In an application embodiment of the present utility model, there are two liquid outlet shielding members 13, which are arranged opposite to each other, and the gap between the two liquid outlet shielding members 13 forms the liquid outlet channel 11. In this embodiment, the liquid outlet shielding members 13 can be arranged in an arc shape and spaced apart from each other, so that the liquid outlet shielding members 13 have a certain gap for liquid to flow out. Optionally, the blocking portions 132 on the two liquid outlet shielding members 13 can be arranged opposite to each other, and the limiting member 42 has two limiting portions 421, which respectively cooperate with the two blocking portions 132 to control the rotation angle.

[0054] Preferably, the preset angle is 60 degrees to 120 degrees, so that the user can rotate the liquid outlet and storage member 20 in a small range to discharge the liquid, and seal the liquid outlet channel 11, which is convenient for user operation.

[0055] The bottle connector 10 is provided with an identification for indicating the opening state of the liquid outlet channel 11, which includes an opening identification ON of the liquid outlet channel 11, a channel closing identification OFF and an indication identification 28 (such as a dot, a triangular dot, a vertical line, etc.) on the liquid outlet storage component 20, etc., to prevent the user from turning the liquid outlet channel 11 too much, to prevent damage to the blocking portion 132, and to reduce the strength requirement of the liquid outlet shielding component 13.

[0056] In other embodiments, there are more than three liquid outlet shielding members 13, each of which is arranged around the bottle mouth seal 40, and the gaps between adjacent liquid outlet shielding members 13 form the liquid outlet channel 11, that is, there are more than three liquid outlet channels 11, which can be specifically arranged according to needs, and the utility model does not impose any restrictions on this.

[0057] Please continue reading Figures 1 to 10 In a further embodiment, at least one air hole 26 is provided on the liquid outlet and storage component 20, and the air hole 26 is used to balance the air pressure of the medicine chamber 21 with the ambient air pressure to avoid the positive pressure or trapped air in the medicine chamber 21 causing insufficient liquid addition, that is, the liquid addition amount does not reach the rated quantity, and the air hole 26 takes in air during use to avoid the negative pressure in the medicine chamber 21 causing poor liquid discharge from the upper medicine component 30, so that the liquid in the medicine chamber 21 can smoothly infiltrate the upper medicine component 30.

[0058] Optionally, the inner diameter of the pore 26 is 0.2-0.5 mm, and the gap sealing principle and the adhesion of the liquid can also be used to make the liquid seal the pore 26, thereby preventing the liquid from flowing out of the pore 26.

[0059] The air hole 26 is located in the groove 24 to prevent the air hole 26 from affecting the appearance of the smear-type medicine applicator 100 . The sealing ring 25 is an O-ring to facilitate smooth exhaust of the air hole 26 .

[0060] Preferably, the air hole 26 is in a frustum (truncated cone, prism, etc.) or columnar shape, that is, the inner diameter of the end of the air hole 26 close to the inner wall of the medicine chamber 21 is smaller, and the inner diameter of the end of the air hole 26 close to the outer wall of the medicine chamber 21 is larger, so as to facilitate exhaust and gap sealing. Moreover, the frustum-shaped and prism-shaped structure makes it difficult for the mold to break when the mold is opened, thereby reducing the mold cost.

[0061] Furthermore, the smear-type drug applicator 100 of the present invention also includes a protective cover (not shown in the figure), which is arranged on the liquid outlet and storage part 20 to play the role of the smear-type drug applicator 100 to prevent dirt from contaminating the one-way valve and the liquid outlet comb teeth.

[0062] Based on the above-mentioned smear-type drug applicator 100, the present invention also provides a smear-type drug applicator (such as Figures 1 to 10 As shown), it includes a medicine bottle 200 and a smear-type medicine applicator 100, and the smear-type medicine applicator 100 is connected to the medicine bottle 200 with a pattern.

[0063] The liquid outlet and storage member 20 is connected to the bottle mouth sealing member 40 by screws 50 so that the two do not move relative to each other. In the initial state, the indicator mark 28 indicates at the mark OFF, and the bottle mouth connector 10 covers the liquid outlet 41. Figure 8 In the state shown, the bottle mouth connector 10 and the bottle mouth seal 40 are sealed using the gap sealing principle, so that the medicine chamber 21 is isolated from the bottle mouth connecting hole 12, that is, the medicine chamber 21 is isolated from the medicine bottle 200.

[0064] When it is necessary to inject liquid into the medicine chamber 21, the smear-type medicine applicator is turned upside down, and the liquid storage member 20 is rotated to the bottom, so that the indicator mark 28 indicates the mark ON. At this time, the liquid outlet channel 11 and the liquid outlet hole 41 overlap (can also be understood as facing each other), as shown in FIG. Fig.10 In the state shown, the opening degree of the liquid outlet channel 11 reaches the maximum. During the rotation process, the liquid in the medicine bottle 200 can flow into the medicine chamber 21. When the medicine chamber 21 is filled with liquid, or when the set scale is reached, the quantitative injection is achieved. Then, the liquid outlet storage component 20 is rotated in the opposite direction so that the indicator mark 28 indicates at the mark OFF. At this time, the liquid outlet channel 11 and the liquid outlet hole 41 are misaligned. At this time, the liquid outlet channel 11 of the bottle mouth connector 10 is completely blocked by the side wall of the bottle mouth seal 40, and the bottle mouth connector 10 and the bottle mouth seal 40 are sealed by a gap.

[0065] In addition, since the blocking portion 132 is provided at each end of the two liquid-discharging shielding members 13, a stop position can be provided during forward and reverse rotation to prevent excessive rotation. As the smear-type drug-applying head 100 has been described in detail above, it will not be repeated here.

[0066] To summarize, the utility model controls the liquid outlet hole of the bottle mouth sealing member to communicate with the liquid outlet channel of the bottle mouth connector by rotating the liquid outlet storage member, so that the medicine chamber is connected to the bottle mouth connecting hole, and the medicine liquid can be allowed to flow into the medicine chamber by inverting or tilting the medicine applicator downward. When the liquid in the medicine chamber reaches the required capacity, it is only necessary to rotate the liquid outlet storage member in the opposite direction to isolate the medicine chamber from the bottle mouth connecting hole and stop the liquid discharge. At this time, the medicine liquid in the medicine chamber can be applied to the skin where medicine is needed, such as the hairline, hairline, local affected areas of the skin, etc., through the medicine applicator, thereby realizing the function of quantitative medicine application. The liquid can be discharged by screwing the liquid outlet storage member. The operation is simple, and the entire bottle mouth connector only uses a few parts, which reduces the material cost, is simple to assemble and has fewer processes, greatly reduces the overall cost, and has high market competitiveness.

[0067] The utility model can prevent the user from turning the bottle mouth connector too much by providing a mark for indicating the opening state of the liquid outlet channel on the bottle mouth connector, thereby preventing the blocking part from being damaged and reducing the strength requirement of the liquid outlet shielding member.

[0068] In addition, by providing air holes on the liquid outlet and storage part, the air pressure of the medicine chamber can be balanced with the ambient air pressure, avoiding the positive pressure or trapped air in the medicine chamber causing insufficient liquid addition, that is, the amount of liquid added does not reach the rated quantity, and the air holes are air-intaken during use, avoiding the negative pressure in the medicine chamber causing poor liquid discharge from the upper medicine part, so that the liquid in the medicine chamber can smoothly infiltrate the upper medicine part. In addition, the air holes are in the shape of a cone, which is convenient for exhaust and gap sealing. Moreover, the truncated cone and prism-shaped structure makes it difficult for the mold to break the needle when the mold is opened, thereby reducing the mold cost.

[0069] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and utility model concept of the utility model, and all these changes or substitutions should fall within the protection scope of the claims attached to the utility model.
