[0027] The beneficial effects of the present application are as follows:

[0028] 1) The present application includes a smearing assembly, a connecting member, an operable member, a discharging assembly and a container assembly. The discharging assembly includes a discharging rod, a transmission member, a compression member and a bottle shoulder. The operable member is installed on the side wall of the connecting member. When applying makeup, the user presses the operable member, so that the material in the container assembly flows through the discharging assembly and into the smearing assembly for the user to use. Therefore, the user can operate the operable member with one hand to complete the replenishment of the smearing assembly, and the use is very convenient;

[0029] 2) In the present application, a discharge assembly is used to connect the container assembly and the smear assembly, and the opening and closing of the discharge port between the smear assembly and the discharge assembly is controlled by the first valve body, and the opening and closing of the discharge port between the container assembly and the discharge assembly is controlled by the second valve body. Therefore, the cosmetic pen has a good sealing function and does not leak materials. Moreover, the first valve body and the second valve body are both one-way valves, so the material or gas in the smear assembly will not flow back into the discharge assembly, and the material or gas in the discharge assembly will not flow back into the container assembly, thereby ensuring the quality of the material and extending the service life of the material.

[0030] 3) The container component and the discharging component in the present application are detachably connected and are equipped with a replacement component. When the material in the bottle body is used up, the old bottle body is replaced with a new bottle body in the replacement component. Therefore, the smearing component and the pressing component in the present application can be reused, reducing the waste of resources;

[0031] 4) In the present application, a compression member is provided. When the compression member is elastic, the compression member is subjected to uniform pressure from the transmission member in the axial direction. When subjected to force, the compression member is compressed and shortened as a whole in its axial direction. When the external force disappears, the compression member stretches and recovers to a relaxed state under the action of its own elastic force. Therefore, the compression member is subjected to uniform force, thereby extending its service life. When the compression member is not elastic, the transmission member directly extends into the accommodating bin of the compression member, and the discharging operation is completed by compressing the volume of the accommodating bin. The compression member and the transmission member are reset by the action of the elastic member. Therefore, the compression member itself will not be deformed, and the service life of the entire cosmetic brush is long. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0042] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

It should be understood that such data can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily need to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0045] Embodiment 1: As Figures 1-5 shown, a side-operated cosmetic pen includes an application assembly 10, a coupling member 30, an operating member 40, a material discharging assembly, and a container assembly 80. The material discharging assembly includes a transmission member 50 and a compression member 60 connected to each other. The compression member 60 has elasticity. The first end of the coupling member 30 is connected to the application assembly 10, and the second end of the coupling member 30 is detachably connected to the container assembly 80. The transmission member 50 and the compression member 60 are installed in the coupling member 30. The operating member 40 is installed on the side wall of the coupling member 30. A first valve body 33 is provided between the first end of the material discharging assembly and the application assembly 10, and a second valve body 34 is provided between the second end of the material discharging assembly and the container assembly 80. In response to the displacement of the operating member 40 due to the applied force, the transmission member 50 acts on the compression member 60 to make the compression member 60 in a compressed state, and the material in the material discharging assembly pushes open the first valve body 33. When the external force applied to the operating member 40 disappears, the compression member 60 returns to the diastolic state and drives the operating member 40 and the transmission member 50 to reset, and the material in the container assembly pushes open the second valve body 34; wherein the operating member 40 can be displaced inwardly of the cosmetic pen, or displaced forward or backward along the cosmetic pen, or slide circumferentially along the cosmetic pen, etc. The way the operating member is displaced by the applied force is not limited as long as the compression member can be made in a compressed state.

[0046] The first end of the connecting member 30 is fixedly connected to the applying assembly 10. The container assembly 80 is detachably mounted on the second end of the connecting member 30. Optionally, the container assembly 80 is screwed or snap-fitted to the second end of the connecting member 30. The container assembly 80 is used to store cosmetic materials. The discharging assembly is used to introduce the materials in the container assembly 80 into the applying assembly 10. The applying assembly 10 is used for makeup application. The discharging assembly is installed in the connecting member 30. Optionally, the applying assembly 10, the discharging assembly, the connecting member 30 and the container assembly 80 are coaxially arranged. The operating member 40 is movably mounted on the side wall of the connecting member 30 and abuts against the transmission member 50. An installation groove 31 is formed on the side wall of the connecting member 30. The operating member 40 is placed in the installation groove 31. The operating member 40 can be a button, a key, a bump, etc. When not in use, as Figure 1 , Figure 4 and Figure 5 shown, the operating member 40 protrudes outside the connecting member 30. The first valve body 33 and the second valve body 34 are in a closed state, that is, the discharging assembly is not connected to the applying assembly 10 and the discharging assembly is not connected to the container assembly 80. When in use, as Figure 3 shown, when the user presses the operating member 40 downward, the operating member 40 pushes the transmission member 50 to the right and compresses the elastic compression member 60. The materials in the compression member 60 are extruded and flow towards the first valve body 33 and push the first valve body 33 open. The materials flow through the gap between the first valve body 33 and the discharging assembly and flow into the applying assembly 10. When the user releases the operating member 40, the compression member 60 returns to the diastolic state and drives the transmission member 50 and the operating member 40 to reset. Since the pressure in the discharging assembly is less than the pressure in the container assembly 80, the materials in the container assembly 80 push the second valve body 34 open and flow into the discharging assembly until the pressures in the discharging assembly and the container assembly 80 reach equilibrium. The first valve body 33 and the second valve body 34 are in a closed state again. At this time, the applying assembly 10 is filled with materials for the user to use. In this cosmetic pen, the operating member is arranged on the side wall of the pen body, so the user can complete the replenishment of the applying assembly with one hand, which is very convenient to use.

[0047] As Figures 1-2 shown, a first inclined surface 41 is provided on the operating member 40, and a second inclined surface 51 matching the first inclined surface 41 is provided on the transmission member 50. The operating member 40 can drive the transmission member 50 to move along the axial direction of the connecting member 30 and compress the compression member 60. The compression member 60 is subjected to a uniform pressure along the axial direction by the transmission member 50. When stressed, the compression member 60 is integrally compressed and shortened along its axial direction. When the external force disappears, the compression member elongates and returns to the diastolic state under the action of its own elastic force. Therefore, the compression member is uniformly stressed, which prolongs its service life; if the compression member is subjected to a force along its radial direction, only a partial area of the compression member is deformed, which easily causes the compression member to fatigue and lose its elasticity.

[0048] The transmission member 50 is internally provided with a material passage, and the compression member 60 is internally provided with a receiving bin. The material passage and the receiving bin communicate with each other. The axial direction of the transmission member 50 and the connecting member 30 is defined by a guide rail and a guide groove. As Figure 1 and Figure 5 shown, the first inclined surface 41 and the second inclined surface 51 are mutually attached. When the operable member 40 is pressed down, by the action of the inclined surface, the operable member 40 gives a component force in the axial direction to the transmission member 50, causing the transmission member to slide to the right to compress the compression member 60, and the material in the receiving bin is extruded and flows to the coating assembly 10. Optionally, as Figure 2 shown, the transmission member 50 is provided with a guide rail in the axial direction, and the connecting member 30 is provided with a guide groove in the axial direction, or the transmission member 50 is provided with a guide groove in the axial direction, and the connecting member 30 is provided with a guide rail in the axial direction. The guide rail is snapped into the guide groove, thus defining the sliding of the transmission member along the axial direction of the connecting member; the compression member 60 can be made of an elastomer or rubber material, that is, a telescopic elastic bladder. For example, the compression member 60 can be a rubber bladder, and the outer shape of the compression member is not limited. Optionally, the outer shape of the compression member is a parallel corrugated shape, an inclined corrugated shape, etc.

[0049] An elastic member 32 is provided between the transmission member 50 and the compression member 60. The first end of the elastic member 32 abuts against the transmission member 50, and the second end of the elastic member 32 abuts against the compression member 60. The elastic member 32 is sleeved outside the compression member 60. When the compression member 60 is compressed, the elastic member 32 is simultaneously compressed. In this way, when the user releases the operable member, the operable member can quickly reset under the restoring force of the elastic member 32, improving the user's operation pleasure and at the same time reducing the burden on the compression member. The elastic member 32 can be a plastic spring, so that all components in the cosmetic pen can be made of plastic materials, which is convenient for recycling and meets the environmental protection requirements.

[0050] In a possible way, the first valve body 33 is provided between the coating assembly 10 and the transmission member 50, and the second valve body 34 is provided between the container assembly 80 and the compression member 60. As Figures 1-2 shown, the transmission member 50 is located on the left side of the compression member 60, and the operable member 20 drives the transmission member 50 to slide to the right to squeeze the compression member 60.

[0051] In another possible way, the first valve body 33 is provided between the coating assembly 10 and the compression member 60, and the second valve body 34 is provided between the container assembly 80 and the transmission member 50. The transmission member is located on the right side of the compression member 60, and the operable member 20 drives the transmission member 50 to slide to the left to squeeze the compression member 60. This embodiment is not shown in the figure.

[0052] The discharging assembly further includes a discharging rod 20 and a bottle shoulder 70. The discharging rod 20 is fixedly installed inside the first end of the connecting member 30, and the discharging rod 20 is fixedly sleeved on the coating assembly 10. The bottle shoulder 70 is fixedly installed inside the second end of the connecting member 30. The first valve body 33 is installed on the discharging rod 20 in an openable and closable manner, and the second valve body 34 is installed on the bottle shoulder 70 in an openable and closable manner.

[0053] As Figure 1 and Figure 3 shown, in the first implementation mode of Embodiment 1, a first discharge port 21 is provided inside the discharging rod 2O. The first end of the transmission member 50 is movably sleeved on the tail of the discharging rod 20. The first valve body 33 is installed in the first discharge port 21. A second discharge port 71 is provided inside the bottle shoulder 70. The first end of the compression member 60 is fixedly installed at the second end of the transmission member 50. The second end of the compression member 60 is fixedly installed inside the bottle shoulder 70. The second valve body 34 is installed in the second discharge port 71. The discharging assembly includes a discharging rod 20, a transmission member 50, a compression member 60, and a bottle shoulder 70 that are arranged in sequence inside the connecting member 30. The discharging rod 20 is fixedly inserted into the coating assembly 10. The first end of the transmission member 50 is movably sleeved on the discharging rod 20, and the transmission member 50 will not be separated from the discharging rod 20 during operation. The first valve body 33 is placed at the first discharge port of the discharging rod 20. When the first valve body fits against the discharging rod, the first discharge port is closed, and the material in the discharging assembly will not flow into the coating assembly. When the first valve body is pushed open, the first discharge port is opened, and the material in the discharging assembly flows into the coating assembly 10 through the first discharge port 21. The second end of the transmission member 50 is fixedly connected to the first end of the compression member 60. The second end of the compression member 60 is fixedly connected to the bottle shoulder 70. As Figure 3 shown, when the transmission member 50 moves to the right, the compression member 60 is compressed and the material inside it flows out. The bottle shoulder 70 is fixedly installed inside the connecting member 30. The container assembly 80 is screwed or snapped onto the bottle shoulder 70. The second valve body 34 is placed at the second discharge port of the bottle shoulder 70. When the second valve body fits against the bottle shoulder, the second discharge port 71 is closed, and the material in the container assembly 80 will not flow into the discharging assembly. When the second valve body 34 is pushed open, the second discharge port 71 is opened, and the material in the container assembly 80 flows into the discharging assembly; in the second implementation mode of Embodiment 1, the only difference from the first implementation mode is that the first end of the transmission member 50 is movably placed inside the bottle shoulder 70, and the second end of the compression member 60 is fixedly connected to the tail of the discharging rod 20.

[0054] Both the first valve body 33 and the second valve body 34 are one-way valves. The opening direction of the first valve body 33 is from the discharging assembly to the applying assembly 10, and the opening direction of the second valve body 34 is from the container assembly 80 to the discharging assembly. In this application, the discharging assembly is used to connect the container assembly and the applying assembly. The opening and closing of the discharging port between the applying assembly and the discharging assembly is controlled by the first valve body, and the opening and closing of the discharging port between the container assembly and the discharging assembly is controlled by the second valve body. Therefore, the makeup pen has good sealing performance and no material leakage will occur. Moreover, since both the first valve body and the second valve body are one-way valves, the materials or gases in the applying assembly will not flow back into the discharging assembly, and the materials or gases in the discharging assembly will not flow back into the container assembly either, thus ensuring the quality of the materials and extending the service life of the materials.

[0055] As Figure 1 , Figure 3 and Figure 5 shown, the makeup pen further includes an outer cap 14. The outer cap 14 covers the applying assembly 10. The applying assembly 10 includes an applying head 11, a pen tip 12 and an applying head seat 13. The applying head 11 is fixedly installed on the applying head seat 13 and the applying head 11 is in communication with the liquid channel in the applying head seat 13. The pen tip 12 is fixedly sleeved outside the applying head 11 and the applying head seat 13. The applying head 11 extends out of the pen tip 12, and the applying head seat 13 is inserted into the applying head 11. The first end of the connecting piece 30 is fixedly installed between the pen tip 12 and the applying head seat 13. The outer cap 14 covers the pen tip 12 to enclose the applying head 11. The materials in the discharging assembly flow into the applying head 11 through the liquid channel in the applying head seat 13 for the user to use.

[0056] As Figure 1 , Figure 3 and Figure 5 shown, the container assembly 80 includes a bottle body 81, a piston 82 and a tail plug 83. The tail plug 83 is tightly plugged at the tail end of the bottle body 81. The piston 82 is hermetically installed in the bottle body 81 inside the tail plug 83. The tail plug 83 is provided with a ventilation hole communicating with the outside. The head of the bottle body 81 is screwed into the bottle shoulder 70, and the tail has the tail plug 83. The bottle body 81 and the tail plug 83 can be of a split structure or an integral structure. When the materials in the bottle body 81 are sucked into the discharging assembly, the outside air enters the bottle body through the ventilation hole, so as to keep the pressure inside and outside the bottle body consistent. The piston is used to push the materials, so that the materials will not remain inside the bottle body, improving the utilization rate of the materials and reducing waste.

[0057] As Figure 6 and Figure 7As shown, the cosmetic pen further includes a replacement component 90, and the replacement component 90 includes a container component 80 and a replacement cap 91. The replacement cap 91 is capped on the container component. In this application, there is also provided a replacement component 90. After the material in the bottle body 81 is used up, the replacement cap is unscrewed and the new bottle body in the replacement component replaces the old bottle body. Therefore, the smearing component and the pressing component in this application can be reused, reducing waste of resources.

[0058] Embodiment 2: As Figure 8 and Figure 9 shown, the difference between this embodiment and Embodiment 1 is that there is no elastic member in this embodiment, and the reset of the operable member is driven by the restoring force of the compression member 60.

[0059] Embodiment 3: A side-operated cosmetic pen includes a smearing component 10, a connecting member 30, an operable member 40, a discharging component, and a container component 80. The discharging component includes a transmission member 50 and a compression member 60 that are connected to each other. An elastic member 32 is provided between the transmission member 50 and the compression member 60. The first end of the connecting member 30 is connected to the smearing component 10, and the second end of the connecting member 30 is detachably connected to the container component 80. The transmission member 50 and the compression member 60 are installed in the connecting member 30. The operable member 40 is installed on the side wall of the connecting member 30. A first valve body 33 is provided between the first end of the discharging component and the smearing component 10, and a second valve body 34 is provided between the second end of the discharging component and the container component 80. In response to the displacement of the operable member 40 under force, the transmission member 50 slides towards the inside of the compression member 60, and the material in the discharging component pushes open the first valve body 33. At this time, the elastic member 32 is in a compressed state. When the external force on the operable member 40 disappears, the elastic member 32 turns to a relaxed state and drives the transmission member 50 and the operable member 40 to reset, and the material in the container component 80 pushes open the second valve body 34; the difference between this embodiment and Embodiment 1 is that: in this embodiment, the transmission member 50 and the compression member 60 are slidably connected, and the transmission member 50 is slidably inserted into the accommodation bin of the compression member 60. The compression member 60 does not have elasticity, that is, the transmission member 50 directly extrudes the material in the accommodation bin, and the compression member itself does not deform, and an elastic member 32 is provided between the transmission member and the compression member. The first end of the elastic member abuts against the transmission member, and the second end of the elastic member abuts against the compression member. The elastic member 32 is used for the reset of the transmission member 50 and the operable member 40.

[0060] The operable member 40 is provided with a first inclined surface 41, and the transmission member 50 is provided with a second inclined surface 51 that cooperates with the first inclined surface 41. The operable member 40 can drive the transmission member 50 to move in the axial direction of the connecting member 30 to compress the compression member 60.

[0068] The operation process of the present application: Taking Embodiment 1 as an example, it includes the following steps:

[0069] Step 1: When not in use, as Figure 1As shown, the operating part 40 protrudes outside the connecting part 30, and the first valve body 33 and the second valve body 34 are in the closed state, that is, the discharging assembly is not connected to the smearing assembly 10 and the discharging assembly is not connected to the container assembly 80;

[0070] Step 2: During use, as Figure 2 shown, when the user presses down the operating part 40, the operating part 40 pushes the transmission part 50 to the right to compress the compression part 60. At the same time, the elastic part 32 is compressed, and the material in the compression part 60 is extruded and flows towards the first valve body 33 to push open the first valve body 33, and the material flows through the first discharge port of the discharge rod to the smearing assembly 10;

[0071] Step 3: When the user releases the operating part 40, the operating part 40 resets under the action of the elastic part 32, and at the same time the compression part 60 recovers. At this time, since the pressure in the discharging assembly is less than the pressure in the container assembly 80, the material in the bottle body 81 pushes open the second valve body 34 and flows towards the compression part 60 until the pressures in the discharging assembly and the container assembly 80 reach equilibrium, and the first valve body 33 and the second valve body 34 are in the closed state again. At this time, the smearing assembly 10 is filled with material for the user to use.

[0072] It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
