Description

Technical Field

[0001] The present invention relates to the technical field of lotion pumps, and in particular to a lotion pump with a function of locking and charging liquid. Background Art

[0002] In the field of cosmetics and personal care products, the purity and freshness of liquids are key factors in ensuring product efficacy and user experience. However, during long-term storage, traditional lotion pumps often have difficulty effectively isolating the impact of the external environment on the liquid, causing the liquid to deteriorate, oxidize or inactivate, especially for light-sensitive liquids (such as ascorbic acid, astaxanthin, etc.).

[0003] For example, a Chinese patent with patent application number CN202320697394.5 discloses a reverse suction external spring lotion pump, including a five-in-one component, a screw thread and a body, the five-in-one component includes a spring, a locking cover, a main column, a secondary column and a piston, the bottom end of the main column passes through the locking cover and is fixedly connected to the secondary column, the locking cover and the main column pass through the connecting spring, the main column and the secondary column are fixedly connected and pass through the piston, the locking cover is clamped and fixed to the upper end of the body inner cavity, the piston includes an inner upper end, an outer upper and lower ends and a lower end face 2, the inner upper end and the inner lower end opened at the bottom of the main column always maintain an active sealing state, the body includes a meson edge, a claw, a buckle rib and an inner wall, the outer upper and lower ends and the inner wall always maintain an active sealing state, and the lower end face 2 forms a locked sealing state with the lower end face 1 set at the bottom of the secondary column. However, like most existing lotion pumps, this anti-suction external spring lotion pump does not have the function of locking the liquid. For light-sensitive liquids, it is difficult to effectively isolate the light-sensitive liquids from the external environment and lacks the protection of light-proof separation, which makes the light-sensitive liquids easily deteriorate, oxidize or inactivate. In addition, for liquids that need to be separated and packaged before use, it is impossible to separate and process them, so that the liquids are mixed in the bottle in advance, which leads to poor product use effect and reduces the user experience of using the product. For example, the visual colors of the two liquids before separation are different from the visual colors of the mixed liquids. Summary of the invention

DETAILED DESCRIPTION

[0041] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0042] like Figures 1 to 8As shown, a lotion pump with a function of locking and loading liquid comprises a pump body 1, and a screw thread 2, a locking cover 3, a push head 4, a main column 5, a secondary column 6, a piston 7, a spring 8 and a buckle 9 assembled on the pump body 1; these structures and installation methods are the same as those of existing lotion pumps, and the lotion pump with a function of locking and loading liquid also comprises a one-way ball valve assembly 10, a liquid filling cylinder 20 and a card cover assembly 30. The one-way ball valve assembly 10 can be movably sealed and connected in the lower end of the pump body 1 and can move in the up and down direction of the pump body 1; when the lotion pump is not operated, the one-way ball valve assembly 10 is automatically closed, effectively preventing the liquid from flowing back and the outside air from entering, and ensuring the long-term freshness and purity of the liquid. The pump body 1 is embedded in the liquid filling cylinder 20; the upper end of the liquid filling cylinder 20 is sealed and connected to the upper end of the pump body 1; it is used to contain and store the liquid. The upper end of the pump body 1 is provided with a first vent hole 11 connecting the outside world with its inner cavity; the lower end of the liquid-filling cylinder 20 is provided with a liquid-filling cavity 201 and a liquid outlet 202 connected to the liquid-filling cavity 201; the card cover assembly 30 is connected to the one-way ball valve assembly 10, and a detachable card sleeve is on the lower end of the liquid-filling cylinder 20 to seal and close the liquid outlet 202. The design of the card cover assembly 30 provides additional sealing separation protection before the liquid is used, effectively isolating the environment of the bottle body. When the secondary column 6 moves downward along the pump body 1, the secondary column 6 presses the one-way ball valve assembly 10 and moves along the bottom of the pump body 1 to push the card cover assembly 30 downward to disengage and open the liquid outlet 202, thereby opening the seal and allowing the liquid to flow out. This process not only ensures the convenience of use, but also maintains a high degree of sealing when not in use.

[0043] On the basis of the pump body 1, the screw thread 2, the lock cover 3, the pressing head 4, the main column 5, the auxiliary column 6, the piston 7 and the spring 8, the one-way ball valve assembly 10 is improved, and a liquid cylinder 20 and a card cover assembly 30 are added for use in combination with the one-way ball valve assembly 10, the liquid to be isolated and stored is stored in the liquid filling cavity 201 of the liquid cylinder 20, and the one-way ball valve assembly 10 and the card cover assembly 30 are used to seal and store the liquid cylinder 20. When in use, by pressing the pressing head 4, the main column 5, the auxiliary column 6, and the piston 7 move downward along the bottom of the pump body 1 synchronously, and the auxiliary column 6 presses the one-way ball valve assembly 10 to move along the bottom of the pump body 1 to push the card cover assembly 30 downward to disengage and open the liquid outlet 202, that is, the auxiliary column 6 moves to press the one-way ball valve assembly 10 The liquid outlet 202 is opened by means of the card cover assembly 30, so that the liquid in the liquid filling cylinder 20 flows into the bottle body correspondingly assembled with the lotion pump. With this design, the lotion pump with the function of locking the liquid has the function of separating the liquid. The locked liquid is in the liquid filling cylinder 20, and the sealed storage effect is good. The light-sensitive liquid can be protected from light. The liquid filling cylinder 20 and the card cover assembly 30 are used as a sealed light-proof structure to extend the shelf life of the product. The liquid that needs to be separated before use can also be separated. When in use, it can be used alone or mixed with the liquid in the bottle body. This not only improves the practicality and durability of the product, but also brings new inspiration to the packaging field of cosmetics and personal care products, and has an excellent user experience.

[0044] In this embodiment, the one-way ball valve assembly 10 includes an inlet pipe 101 and a one-way ball valve body 102; the one-way ball valve body 102 is arranged in the inlet pipe 101; the lower end of the inlet pipe 101 is connected with the card cover assembly 30; an upper ring sleeve 40 is provided on the inner wall of the lower end of the pump body 1; the upper ring sleeve 40 has a through pipe hole 401 for the lower end of the inlet pipe 101 to movably pass through; the outer wall diameter of the upper end of the inlet pipe 101 is smaller than the caliber of the through pipe hole 401; a lower ring sleeve 50 is provided on the outer wall of the inlet pipe 101, which is compatible with the upper ring sleeve 40 and is located below the upper ring sleeve 40; the outer wall of the lower ring sleeve 50 is movably sealed and matched with the inner wall of the pump body 1; after the secondary column 6 completely pushes the inlet pipe 101 to move downward, the lower ring sleeve 50 is located in the pump body 1. The one-way ball valve assembly 10 is formed by setting the liquid inlet pipe 101 and the one-way ball valve body 102. When the lotion pump is not operated, that is, when the head 4 is not pressed, the one-way ball valve body 102 is automatically closed, effectively preventing the liquid from flowing back and the outside air from entering the bottle body, ensuring the long-term freshness and purity of the liquid, and preventing the liquid from being contaminated. At the same time, the upper ring sleeve 40 and the lower ring sleeve 50 that match each other are respectively set on the inner wall of the lower end of the pump body 1 and the outer wall of the liquid inlet pipe 101. The upper ring sleeve 40 and the lower ring sleeve 50 form a good sealing structure, so that the one-way ball valve assembly 10 and the pump body 1 have a good sealing effect, which can prevent the liquid in the liquid cylinder 20 from entering the pump body 1, so that the liquid cylinder 20 can achieve the effect of sealing and storing the liquid. At the same time, it also avoids the inner cavity of the pump body 1 from being connected with the inner cavity of the bottle body, preventing the liquid from being contaminated.

[0045] In order to further strengthen the movable sealing connection effect between the one-way ball valve assembly 10 and the pump body 1, a first sealing ring 60 is sleeved in the upper ring sleeve 40. By adding the first sealing ring 60 on the basis of the sealing between the upper ring sleeve 40 and the lower ring sleeve 50, the sealing effect between the one-way ball valve assembly 10 and the pump body 1 can be further strengthened, and the liquid in the liquid cylinder 20 can be better prevented from entering the pump body 1, so that the liquid cylinder 20 can achieve the effect of sealing and storing the liquid. Specifically, in the present embodiment, the lower ring sleeve 50 is a ring sleeve structure formed by wrapping around the outer wall of the liquid pipe 101 with an L-shaped cross-section; the upper ring sleeve 40 is a T-shaped ring sleeve structure, and the first sealing ring 60 is adapted to fit in the groove formed by the upper ring sleeve 40 and the lower end inner wall of the pump body 1, and the lower end of the upper ring sleeve 40 is adapted to fit into the card sleeve

[0046] The combination of the three forms a tighter sealing structure, so that the liquid-filling cylinder 20 can achieve the effect of sealing and storing the liquid.

[0047] In order to better push the liquid inlet pipe 101 so as to open the liquid outlet 202, the lower end of the sub-column 6 has a pushing embedded part 61 that can be movably embedded in the liquid inlet pipe 101 and can be removed from the upper end opening of the liquid inlet pipe 101. The pushing embedded part 61 can be a T-shaped structure. In addition, a liquid outlet hole 1011 is provided on the outer wall of the upper end of the liquid inlet pipe 101. When in use, and in the process of the pushing embedded part 61 being embedded in and removed from the upper end opening of the liquid inlet pipe 101, the design of the liquid outlet hole 1011 can speed up the liquid feed to enter the pump body 1, and the liquid outlet effect is better. The liquid outlet hole 1011 can be 1, 2 or more than 2, which can be reasonably designed according to the needs. The liquid outlet hole 1011 can be a round hole, a square hole, and a hole of regular or irregular shape.

[0048] In this embodiment, the card cover assembly 30 includes a tube section 301 and a card cover body 302; the tube section 301 is connected to the lower end of the one-way ball valve assembly 10; the card cover body 302 is connected to the outer wall of the tube section 301 and is detachably inserted into the lower end of the liquid-filling cylinder 20 to seal and close the liquid outlet 202. By arranging the tube section 301 and the card cover body 302 to form the card cover assembly 30, the connection with the liquid inlet pipe 101 can be achieved, and the card cover body 302 can seal and close the liquid outlet 202, so that the liquid-filling cylinder 20 can achieve a good effect of storing liquid, the structure is simple, and the card assembly is convenient. In addition, when in use, it is convenient to open the liquid outlet 202, which is conducive to the liquid flowing out of the liquid outlet 202 and entering the bottle body. It can be used alone or mixed with the liquid in the bottle body, which not only improves the practicality and durability of the product, but also brings new inspiration to the packaging field of cosmetics and personal care products, and has an excellent user experience.

[0049] Preferably, the lower end of the liquid-filling cylinder 20 has a snap-fitting edge 205; the position corresponding to the snap-fitting edge 205 on the snap-fitting cover 302 is provided with a snap-fitting groove 3021 along the edge connected with a snap-fitting sleeve of the snap-fitting edge 205. By inserting the snap-fitting sleeve of the snap-fitting edge 205 into the snap-fitting groove 3021 along the edge, a detachable sealed connection between the snap-fitting cover 302 and the lower end of the liquid-filling cylinder 20 is achieved, and the liquid outlet 202 can be sealed and closed, so that the liquid-filling cylinder 20 can achieve a good effect of storing liquid and has better sealing performance.

[0050] In order to further enhance the connection stability and sealing performance between the embedded edge 205 and the edge embedded groove 3021, a convex structure 3022 is provided on the groove wall of the edge embedded groove 3021. The convex structure 3022 can be an annular convex edge structure or a convex grain structure.

[0051] In order to strengthen the connection stability between the card cover assembly 30 and the liquid cylinder 20, improve the sealing performance and prevent liquid leakage, the card cover assembly 30 also includes a support contact block 303; a plurality of the support contact blocks 303 are evenly arranged on the top of the card cover body 302 around the tube section 301 and are adapted to contact and connect with the inner wall of the liquid cylinder 20. After the liquid flows out from the liquid outlet 202, it flows out from the space formed between the two adjacent support contact blocks 303 and the top surface of the card cover body 302. By arranging the support contact block 303 on the card cover body 302, the contact area with the inner wall of the liquid cylinder 20 is increased, the connection stability between the card cover assembly 30 and the liquid cylinder 20 is strengthened, the sealing performance is better, and liquid leakage is prevented. In the present embodiment, the support contact block 303 is in the shape of a triangle, and of course it can also be in the shape of an arc cylinder, as well as other structural shapes, which can be reasonably designed according to the needs.

[0052] In this embodiment, the upper end of the liquid-filling cylinder 20 has a ventilation cavity 203 connected to the first ventilation hole 11; the upper end of the liquid-filling cylinder 20 also has a second ventilation hole 204 connected to the ventilation cavity 203. By providing the ventilation cavity 203 and the second ventilation hole 204 at the upper end of the liquid-filling cylinder 20, the external environment is connected to the first ventilation hole 11, the air pressure inside and outside the bottle is balanced, and the liquid is conveniently discharged for use when in use.

[0053] In this embodiment, the inner wall of the upper end of the liquid filling cylinder 20 has a first supporting ring edge 70 for the outer wall of the pump body 1 to fit through; the ventilation cavity 203 and the liquid filling cavity 201 are respectively located above and below the first supporting ring edge 70; the ventilation cavity 203 and the liquid filling cavity 201 are connected through the ring opening of the first supporting ring edge 70; the upper outer wall of the pump body 1 is provided with a second supporting ring edge 80 located above the first supporting ring edge 70; after the outer wall of the pump body 1 fits through the first supporting ring edge 70, the upper inner wall of the liquid filling cylinder 20 is connected to the upper outer wall of the pump body 1, and the second supporting ring edge 80 is pressed and sealed on the first supporting ring edge 70 by a second sealing ring 90 mounted on the pump body 1. By providing the first supporting ring edge 70, the second supporting ring edge 80 and the second sealing ring 90, the sealing performance of the liquid filling cavity 201 is enhanced, and the liquid can be better stored, so that the lotion pump with the function of locking the liquid filling has a good function of separating the liquid filling, and the liquid filling is locked in the liquid filling cylinder 20, and the sealing storage effect is good. At the same time, the ventilation cavity 203 and the liquid filling cavity 201 are sealed and separated to avoid affecting the use of each of them.

[0054] In order to better ensure that the liquid in the upper end of the liquid-filling cylinder 20 can flow out smoothly, the second vent hole 204 is designed so that the lower edge of the second vent hole 204 is lower than the upper end surface of the second supporting ring 80 .

[0055] Preferably, the upper inner wall of the liquid-filling cylinder 20 is threadedly connected to the upper outer wall of the pump body 1, which has a simple structure, is easy to disassemble and assemble, and achieves a good sealing effect between the two. Of course, the connection relationship between the upper inner wall of the liquid-filling cylinder 20 and the upper outer wall of the pump body 1 can also be reasonably designed according to demand to achieve a good sealing effect, such as a sleeve connection, a buckle 9 connection, etc. In order to enhance the sealing of the upper end of the liquid-filling cylinder 20, a third sealing ring 100 is sleeved on the upper outer wall of the liquid-filling cylinder 20. The third sealing ring 100 is provided, and the third sealing ring 100 is located in the screw thread 2. The lotion pump is embedded in the bottle body as a whole, and the screw thread 2 is threadedly connected to the bottle mouth of the bottle body. The design of the third sealing ring 100 can enhance the sealing of the upper end of the liquid-filling cylinder 20 and prevent the liquid from flowing in or out from the third sealing ring 100.
