DETAILED DESCRIPTION

[0035] The following will be combined with the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described in this application are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0036] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the following drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the objects used in this way can be interchanged where appropriate so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0037] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0038] Example: Figures 1 to 14 As shown, a push-type pump core assembly includes a housing 110, a valve stem 120, an elastic member 130, a bushing 140, a piston 150 and a piston seat 160. The bushing 140 and the piston seat 160 are fixedly installed in the housing 110. The valve stem 120 is fixedly connected to the piston 150. The piston 150 is installed in the piston seat 160. An elastic member 130 is provided between the valve stem 120 and the bushing 140. A first stopper 121 is provided on the valve stem 120, and a second stopper 121 is provided on the bushing 140. The moving part 141, the valve stem 120 can drive the piston 150 to move axially along the piston seat 160 to complete the material suction operation. Before the valve stem 120 moves, the first stop part 121 and the second stop part 141 are disengaged from each other. When the valve stem 120 moves to the maximum stroke, the first stop part 121 abuts against the second stop part 141, that is, the first stop part 121 can abut against the second stop part 141 to limit the maximum stroke of the valve stem 120. The elastic member 130 is used to reset the valve stem 120.

[0039] like Figure 1As shown, bushing 140 is fixedly mounted to the upper open end of housing 110. Optionally, bushing 140 and housing 110 are secured by means of a snap fit, interference fit, fasteners, or the like. Piston seat 160 is interference-fitted to the inner sidewall of housing 110, and piston seat 160 forms an airtight contact with the inner sidewall of housing 110. During use, pump core assembly 100 is installed within outer sleeve assembly 200, forming a complete cosmetic container. A discharge channel is provided inside the valve stem 120 and the piston 150. Initially, the elastic member 130 is in a natural state, and the piston 150 and the piston seat 160 are in an airtight fit. When the user presses the valve stem 120 downward, the valve stem 120 and the piston 150 move synchronously downward along the axial direction of the piston seat 160 until the first stop portion 121 on the valve stem 120 presses against the second stop portion 141 on the bushing 140. At this time, the elastic member 130 is compressed, and the airtight state between the piston 150 and the piston seat 160 is released to suck the cosmetic material into the discharge channel to complete the suction operation.

[0040] In the present application, the first stop portion 121 is provided on the valve stem 120, and the second stop portion 141 is provided on the bushing 140. The first stop portion 121 and the second stop portion 141 are used to limit the maximum stroke of the valve stem 120, thereby controlling the discharge amount of the pump core assembly 100 each time, ensuring the quantitative discharge of the pump core assembly 100, and facilitating user use; in the present application, the first stop portion 121 and the second stop portion 141 are designed inside the pump core assembly 100, thereby simplifying the structure of the cosmetic container and facilitating large-scale processing and production of cosmetic containers.

[0041] In one possible implementation, Figure 9 and Figure 10 As shown, the outer side wall of the valve stem 120 extends radially outward to form a first stopper 121, that is, the first stopper 121 protrudes from the valve stem 120 in the radial direction of the valve stem 120. Figure 11 and Figure 12 As shown, the upper surface of the bushing 140 extends axially upward to form a second stop portion 141. The valve stem 120 is inserted into the bushing 140, and the valve stem 120 moves downward. When the first stop portion 121 moves to the second stop portion 141, the second stop portion 141 blocks the first stop portion 121 to prevent the valve stem 120 from further descending.

[0042] In another possible embodiment, the outer sidewall of the valve stem 120 extends radially outward to form the first stop portion 121, and the inner sidewall of the bushing 140 extends radially inward to form the second stop portion 141. That is, the second stop portion 141 is formed by extending inward along the inner sidewall of the bushing 140 and can also serve to limit the first stop portion 121.

[0043] In this application, the first stop portion 121 is arranged on the valve stem 120, and the second stop portion 141 is arranged on the sleeve 140. The first stop portion 121 and the second stop portion 141 are used to limit the maximum stroke of the valve stem 120, thereby controlling the discharge amount of the pump core assembly 100 each time, ensuring the quantitative discharge of the pump core assembly 100, and facilitating user use.

[0044] like Figure 2 As shown, the width of the first stopper 121 is H1, and the distance between the uppermost end of the second stopper 141 and the valve stem 120 is H2, where H1>H2. This ensures that when the valve stem 120 moves downward, the first stopper 121 can be blocked by the second stopper 141, thereby preventing the valve stem 120 from moving further downward.

[0045] like Figure 9 and Figure 11 As shown, in the first embodiment, a circle of first stop portions 121 is provided on the valve stem 120, and a circle of second stop portions 141 is provided on the bushing 140, that is, a full circle of first stop portions 121 is provided in the circumferential direction of the valve stem 120, and a full circle of second stop portions 141 is provided in the circumferential direction of the bushing 140. This ensures that when the first stop portion 121 runs to the position of the second stop portion 141, the two can interfere with each other.

[0046] In the second embodiment, a circle of first stop portions 121 is provided on the valve stem 120, and second stop portions 141 arranged at intervals from each other are provided on the bushing 140, that is, a full circle of first stop portions 121 is provided in the circumferential direction of the valve stem 120, and a plurality of second stop portions 141 arranged at intervals from each other are provided in the circumferential direction of the bushing 140, which can also achieve the purpose of mutual interference between the first stop portion 121 and the second stop portion 141.

[0047] In the third embodiment, the valve stem 120 is provided with first stoppers 121 spaced apart from one another, and the bushing 140 is provided with a circle of second stoppers 141. Alternatively, the valve stem 120 may be provided with a plurality of first stoppers 121 spaced apart from one another in the circumferential direction, and the bushing 140 may be provided with a complete circle of second stoppers 141 in the circumferential direction.

[0048] like Figure 1 、 Figure 11 and Figure 12As shown, a portion of the lower inner side wall of the second stopper 141 is in contact with the outer side wall of the valve stem 120, and an escape groove 144 is provided on the inner side wall of the bushing 140. The valve stem 120 and the second stopper 141 are arranged in contact with each other to guide the valve stem 120 when it moves downward, ensuring that the valve stem 120 does not shake or rotate; the escape groove 144 is provided on the inner side wall of the bushing 140, and the escape groove 144 is located below the second stopper 141, so that a certain gap is formed between the valve stem 120 and the bushing 140. After the pump core assembly is pressed multiple times, the valve stem may deform. This gap provides a buffer space for the deformation of the valve stem 120, ensuring that the discharge effect of the pressing is not affected by the deformed valve stem 120.

[0049] like Figure 7 and Figure 8 As shown, the elastic member 130 is made of plastic material, and the outer surface of the elastic member 130 is a spiral structure. Figure 1 and Figure 3 As shown, the first end of the elastic member 130 abuts against the valve stem 120, and the second end of the elastic member 130 abuts against the bushing 140. By making the elastic member 130 from plastic, the entire pump core assembly is made of plastic, reducing production costs and facilitating product recycling and sorting. The helical structure of the elastic member 130, similar to a bellows, reduces the risk of unusual noise when pressed, ensuring smooth discharge and enhancing user comfort.

[0050] like Figure 9 and Figure 10 As shown, the first end of the valve stem 120 extends radially outward to form a circle of convex edges 123, and the convex edges 123 extend downward to form side walls. The side walls and the first stopper 121 form a groove 124, as shown in FIG. Figure 1 As shown, the first end of the elastic member 130 is inserted into the groove 124 and abuts against the convex edge 123. Figure 10 As shown, the inner side wall of the valve stem 120 is provided with a rib 122. Figure 13 As shown, the outer wall of the piston 150 is provided with a circle of grooves 152 . When the piston 150 is inserted into the valve stem 120 , the ribs 122 are engaged with the grooves 152 to securely mount the valve stem 120 and the piston 150 .

[0051] like Figure 1 、 Figure 11 and Figure 12As shown, the first end of the housing 110 is fixedly mounted with a bushing 140, and the second end of the housing 110 is fixedly mounted with an intake valve 170. An outer ring 142 is fixedly provided on the outside of the bushing 140, and a mounting groove 143 is formed between the outer ring 142 and the bushing 140. The first end of the housing 110 is inserted into the mounting groove 143, and the housing 110 and the outer ring 142 are engaged and fixed, thereby fixing the bushing 140 to the housing 110. The second end of the housing 110 is internally mounted with an intake valve 170, which draws external cosmetic material into the interior of the pump core assembly through the intake valve 170.

[0052] like Figure 13 and Figure 14 As shown, the piston 150 is provided with a feed hole 151. When the elastic member 130 is in a natural state, that is, the pump core assembly is in an initial state, as shown in FIG. Figure 15 and Figure 16 As shown, the first stopper 121 is located above the second stopper 141, the piston 150 is airtightly attached to the piston seat 160, and the piston seat 160 seals the feed hole 151. Figure 17 As shown, when the user presses the valve stem 120, the valve stem 120 drives the piston 150 to move axially along the piston seat 160, the elastic member 130 is in a compressed state, and a gap is formed between the piston 150 and the piston seat 160 to complete the material suction operation. That is, after the piston 150 moves downward, the airtight state between the piston 150 and the piston seat 160 is released and a gap is formed. The material enters the piston through the gap and the feed hole 151 to complete the material suction operation. Figure 18 As shown, the first stopper 121 abuts against the second stopper 141, and the valve stem 120 completes the movement of the maximum stroke. When the user releases the valve stem 120, the elastic member 130 recovers and returns the valve stem 120 and the piston 150 to the initial state.

[0053] like Figure 15-18 As shown, a cosmetic container includes a pump core assembly 100 and an outer sleeve assembly 200, the outer sleeve assembly 200 includes a bottle body 210, an inner ring member 220, a pressing member 230 and an outer cover 240, the pump core assembly 100 is installed in the bottle body 210, the inner ring member 220 is screwed to the bottle body 210 to fix the pump core assembly 100 on the bottle body 210, the pressing member 230 is connected to the valve stem 120, and the pressing member 230 can drive the valve stem 120 to move axially along the shell 10, and the outer cover 240 covers the inner ring member 220.

[0054] like Figure 16As shown, the housing 110 is mounted on the open end of the bottle body 210, and a gasket 180 is provided between the housing 110 and the bottle body 210. A fixing rod 231 is fixed to the pressing member 230, and a discharge channel 232 is provided on the pressing member 230. The fixing rod 231 is inserted into the open end of the valve stem 120 and the fixing rod 231 is fixedly engaged with the valve stem 120. Cosmetic material is placed in the bottle body 210. When the user presses the pressing member 230, the pressing member 230 drives the valve stem 120 and the piston 150 to move downward until the first stop portion 121 abuts against the second stop portion 141. Figure 18 As shown, at this time, the elastic member 130 is compressed, the airtight state between the piston 150 and the piston seat 160 is released and a gap is formed, and the cosmetic material in the bottle body 210 flows out of the container through the suction valve 170, the gap, the feed hole 151 and the discharge channel 232 for use by the user.

[0055] When the user releases the pressing member 230, the elastic member 130 returns to its original position, returning the pressing member 230, the valve stem 120, and the piston 150 to their original positions. In this application, the first stopper 121 and the second stopper 141 are designed into the pump core assembly, thereby reducing the difficulty of manufacturing the various components of the cosmetic container and facilitating product precision control. The interaction between the first stopper 121 and the second stopper 141 can control the amount of cosmetic material discharged each time, making it easier for consumers to use.

[0056] like Figure 15 As shown, the bottle body 210 includes an outer bottle 211 and an inner bottle 212 fixedly installed in the outer bottle 211. In a possible embodiment, a scraper plug 250 is provided in the inner bottle 212, and the scraper plug 250 is airtightly attached to the inner wall of the inner bottle 212. The scraper plug 250 moves upward to squeeze the cosmetic material in the bottle into the pump core assembly, thereby improving the utilization rate of the cosmetic material and reducing the waste of resources. However, the sealing requirements for the pump core assembly are relatively high, and it is suitable for high-value cosmetic materials.

[0057] In another possible embodiment, a straw is provided within the inner bottle 212 and is sleeved onto the free end of the housing 110. The upper end of the straw is fixedly mounted to the free end of the housing 110, while the lower end of the straw is located within the body of the inner bottle 212. The straw is used to draw cosmetic materials from the bottle, resulting in a simple structure and ease of use.

[0058] The beneficial effects of this application include:

[0059] (1) In the present application, the first stop portion is provided on the valve stem, and the second stop portion is provided on the bushing. The first stop portion and the second stop portion are used to limit the maximum stroke of the valve stem, thereby controlling the discharge amount of the pump core assembly each time, ensuring quantitative discharge of the pump core assembly, and facilitating user use; in the present application, the first stop portion and the second stop portion are designed inside the pump core assembly, thereby simplifying the structure of the cosmetic container and facilitating large-scale processing and production of the cosmetic container.

[0060] (2) In the present application, the valve stem and the second stop portion are arranged to fit together, which can guide the valve stem when it moves downward, ensuring that the valve stem does not shake or rotate; an avoidance groove is opened on the inner wall of the bushing to form a certain gap between the valve stem and the bushing. After the pump core assembly is pressed multiple times, the valve stem may be deformed. The gap provides a buffer space for the deformation of the valve stem, ensuring that the discharge effect of the pressing will not be affected by the deformed valve stem.

[0061] (3) In the present application, the elastic member is made of plastic material, so that the entire pump core assembly is made of plastic material, which extends the service life of the product, reduces the production cost of the product, and facilitates the recycling and classification of the product; the elastic member is made into a spiral structure, which is similar to the shape of a bellows, and is not easy to produce abnormal noise when pressed, thereby ensuring smooth discharge and improving user comfort.

[0062] It should be noted that those skilled in the art may make a number of modifications and improvements without departing from the concept of this application, and these modifications and improvements are all within the scope of protection of this application. Therefore, the scope of protection of this patent application shall be based on the appended claims.
