Description

Technical Field

[0001] This application relates to the field of foam pump technology, and more specifically, to a foam pump pusher locking mechanism and a foam pump. Background Technology

[0002] As we all know, with social progress, more and more convenient daily necessities are now widely used in people's lives. People are increasingly concerned about their health and hygiene, and to maintain cleanliness, they often use cleaning liquids when washing their hands, face, or showering. To meet this need, a large number of facial cleansers, hand soaps, and shower gels are available on the market. For ease of use, these liquids are usually packaged in bottles, allowing users to pour out a measured amount for cleaning. Previously, users had to manually tilt the container to allow the liquid to flow out, but this was inconvenient and often resulted in waste. To overcome this, modern containers typically have a foam pump attached to the top. Users can press the pump to dispense a measured amount of liquid for convenient use.

[0003] However, when products containing the aforementioned liquids are shipped from the factory, the push-button in its pop-up state is usually locked by a snap on the cap to prevent it from moving. However, the push-button takes up a lot of space when it is popped up, increasing packaging space. Moreover, the cap locking method makes it difficult for the cap to rotate freely. When labeling, the cap and push-button need to maintain a specific posture to achieve labeling, which means that the posture of the cap needs to be adjusted to achieve labeling. This locking method also increases the difficulty of labeling and affects the production efficiency of the product. Utility Model Content

[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0046] The technical solutions of this utility model and their effects are described below through several exemplary embodiments. It should be noted that the following embodiments can be referenced, borrowed from, or combined with each other. Identical terms, similar features, and similar implementation steps in different embodiments will not be repeated.

[0047] The foam pump push-lock mechanism and foam pump provided in this application are intended to solve at least one technical problem existing in the prior art.

[0048] Optionally, a foam pump head locking mechanism is provided in the foam pump. This locking mechanism fixes the head 1 at the factory to prevent the head 1 from popping up and to reduce the space occupied by the head 1.

[0049] This application provides a foam pump pusher locking mechanism, such as... Figures 1-4 As shown, the device includes a pusher head 1 and a locking cover 3. The locking cover 3 is hollow, forming a tubular cavity, and the inner wall of the tubular cavity is provided with a first thread. The pusher head 1 includes a first tubular component 101 disposed at the lower part of the pusher head 1. The bottom of the first tubular component 101 is inserted into the tubular cavity, and the top of the outer side of the first tubular component 101 is provided with a second thread that matches the first thread. The first thread can be located at the top of the tubular cavity. By utilizing the positions of the first and second threads, the height of the pusher head 1 can be minimized, reducing the space occupied in the packaging.

[0050] Optionally, the first thread can be an internal thread, and the second thread can be an external thread. The first and second threads enable the threaded connection between the pusher 1 and the locking cover 3.

[0051] In one embodiment, the top of the push head 1 may be provided with characters or markings indicating the direction of rotation. Specifically, these characters or markings can instruct the user to rotate the push head 1 counterclockwise in the locked state, thereby popping the push head 1 up. When the push head 1 pops up, pressing it down causes the first thread to contact the second thread, and then rotating the push head 1 clockwise causes it to engage with the threads of the locking cover 2 to lock the push head 1.

[0052] Optionally, the top of the pusher 1 may be provided with a liquid outlet, which is connected to the first pipe 101. When the foam pump is installed on the container, the liquid to be sprayed is sprayed out along the path formed by the first pipe 101 and the liquid outlet.

[0053] Optionally, the pusher 1 further includes a second tube 102, with the first tube 101 disposed inside the second tube 102, and the inner diameter of the second tube 102 being larger than the outer diameter of the locking cap 3. The locking cap 3 has a first annular groove on the side near the pusher 1 to accommodate the bottom of the second tube 102, and the shape of the first annular groove matches the shape of the bottom of the second tube. The first annular groove has an air hole for balancing the internal and external air pressure. When the pusher 1 is pressed, the space inside the bottle can reach the outside of the bottle through the air hole, and when the pusher 1 is released, the air outside the bottle can reach the inside of the bottle through the air hole.

[0054] In one embodiment, the length of the second pipe 102 is less than the length of the first pipe 101, and the bottom of the second pipe 102 near the first pipe 101 can extend toward the lock cover 3 to form an annular protrusion.

[0055] Optionally, the lock cover 3 includes a third tube and an annular member 31. The third tube is hollow to form a tube cavity. The bottom of the first tube 101 is connected to the annular member 31. The annular member 31 surrounds the third tube. The bottom of the inner wall of the annular member 31 is connected to the third tube. The inner wall of the annular member 31 and the bottom of the third tube form a first annular groove to accommodate the bottom of the second tube 102. The top of the inner wall of the annular member 31 is inclined away from the third tube.

[0056] Optionally, the side of the first annular groove away from the third pipe can form an annular platform that matches the annular protrusion. When the pusher 1 is in the locked state, the annular protrusion on the first pipe 101 can cooperate with the annular platform in the first annular groove, thereby improving the sealing effect of the product.

[0057] In one embodiment, when the pusher 1 is in the locked state, the bottom of the second tube 102 is inserted into the first annular groove and fits against the first annular groove, thereby sealing the air hole in the first annular groove. This prevents the internal liquid from flowing out of the bottle through the air hole due to shaking or other reasons during transportation, or prevents external liquid or impurities from entering the bottle through the air hole. Furthermore, the air hole is not connected to the pump core of the foam pump, effectively avoiding the problem of liquid, air or impurities entering the pump core and effectively preventing the performance of the pump core from being affected.

[0058] Optionally, the locking cover 3 may further include a fourth tube 32, the outer diameter of which is smaller than the inner diameter of the second tube 102. The fourth tube 32 surrounds the third tube, and its bottom is connected to the outer wall of the third tube. The top height of the fourth tube 32 may be the same as the top height of the third tube. When the locking pusher 1 is engaged, the fourth tube 32 and the third tube are located within the gap between the first tube 101 and the second tube 102.

[0059] Optionally, it also includes a toothed cap 8, the top of which is located on the side of the annular member 31 away from the pusher head 1. The top of the toothed cap 8 has a through hole, the diameter of which is smaller than the outer diameter of the annular member 31. The inner side of the toothed cap 8 has a third thread 81 for screwing and fixing to the bottle neck. The toothed cap 8 is not fixedly connected to the locking cap 3, thereby ensuring that the toothed cap 8 can be freely rotated when the pusher head is locked. This facilitates quick adjustment of the posture of the toothed cap 8 during labeling, allowing the toothed cap 8 and the pusher head 1 to maintain a specific posture for labeling operations.

[0060] In one embodiment, the diameter of the through hole at the top of the tooth cap 8 is greater than the outer diameter of the fourth tube 32.

[0061] The foam pump pusher locking mechanism provided in this embodiment includes a pusher 1 and a locking cover 3. The locking cover 3 is hollow, forming a tubular cavity, and the inner wall of the tubular cavity is provided with a first thread. The pusher 1 includes a first tubular component 101 disposed at the lower part of the pusher 1. The bottom of the first tubular component 101 is inserted into the tubular cavity, and the top of the outer side of the first tubular component 101 is provided with a second thread that matches the first thread. This embodiment utilizes the threaded connection between the locking cover 3 and the pusher 1 to lock the pusher 1, which can effectively reduce the space occupied by the pusher 1 in the locked state, reduce packaging space, and ensure the free movement of the toothed cap 8, facilitating rapid labeling and effectively improving production efficiency.

[0062] Based on the same inventive concept, this application also provides a foam pump, such as Figures 1-13 As shown, the foam pump of this application includes a pump core and a foam pump pusher locking mechanism as described in the above embodiment, wherein the pump core is interference-connected with the lock cover 3.

[0063] Optionally, the pump core and the locking cover 3 can be relatively fixed by an interference connection between the pump core and the locking cover 3.

[0064] Optionally, the pump core includes a suction mechanism comprising a cylinder 12, a large lever 4, a small lever 6, a piston seat 14, and a piston 13. The cylinder 12 and the toothed cover 8 are connected without interference. The cylinder 12 is hollow to form a communicating cavity, and the communicating cavity extends through the end of the cylinder 12 facing the locking cover 3 to form a communicating opening. The top side of the communicating opening is embedded in the locking cover 3. The top of the large lever 4 is inserted into the tube cavity, and the outer side of the bottom of the large lever 4 is attached to the inner wall of the communicating cavity. The top of the small lever 6 is connected to the large lever 4, and the top of the piston seat 14 is connected to the bottom of the small lever 6. The piston 13 is sleeved on the piston seat 14, and the outer side of the piston 13 abuts against the inner wall of the communicating cavity.

[0065] Optionally, the annular part 31 is recessed on the side facing the cylinder 12 to form a second annular groove, the top of the communication port can be embedded in the second annular groove, and the air hole can communicate with the second annular groove.

[0066] Optionally, the nut 12 further includes an annular support platform 121, which surrounds and is fixed to the outer wall of the nut 12. The annular support platform 121 is located below the annular member 31, and the top side of the tooth cover 8 is located between the annular support platform 121 and the annular member 31.

[0067] Optionally, a gasket 7 may be provided on the side of the annular support platform 121 away from the annular component 31. The gasket 7 surrounds the cylinder 12, and when the foam pump is fixed to the bottle mouth by the cap 8, the gasket 7 improves the sealing effect. One or more openings communicating between the inside and outside of the cylinder 12 may also be provided on the side wall of the cylinder 12. These openings may be located at the position where the annular support platform 121 is located. When the pusher 1 is pressed down or released, the opening, the second annular groove, the air hole, and the first annular groove form an airflow channel, through which the air pressure inside and outside the bottle is balanced.

[0068] In one embodiment, there can be two openings, which can be symmetrically arranged on the side wall of the cylinder and located on the side of the gasket 7 near the cylinder 12.

[0069] Optionally, it also includes a blade 5, which is arranged around the thin plate 6 and the bottom of the blade 5 extends away from the thin plate 6. The large plate 4 has a plurality of small holes in the area corresponding to the blade 5.

[0070] In one embodiment, the smaller paddle 6 includes a paddle shaft 62 and a supporting platform 61. One end of the paddle shaft 62 passes through the supporting platform 61 and contacts the larger paddle 4. A blade 5 is fixed to the side of the supporting platform 61 near the larger paddle 4. The paddle shaft 62 is hollow, and its internal space communicates with the internal space of the first pipe fitting 101 through the larger paddle 4. The blade 5 is disposed on the side of the supporting platform 61 near the larger paddle 4, and the supporting platform 61 has multiple protrusions that can be arranged circumferentially along the paddle shaft 62.

[0071] Optionally, the pump core also includes a mesh 2. The top of the large lever 4 is recessed to form a first receiving groove, and the bottom of the first receiving groove is connected to the communicating cavity. The mesh 2 is disposed in the first receiving groove, and the outer side of the mesh 2 is attached to the inner wall of the first receiving groove. The outer diameter of the first receiving groove is smaller than the inner diameter of the first pipe fitting 101. The liquid generated after pressing the pusher 1 passes through the mesh 2 and forms foam.

[0072] Optionally, the bottom of the first receiving groove may be provided with a hole, which is opposite to the racket shaft 62 on one side of the racket 4.

[0073] Optionally, the pump core also includes a seat 11 and a spring 10. The communicating cavity includes a first cavity and a second cavity. A piston 13 and a piston seat 14 are disposed in the second cavity. The top of the second cavity is connected to the bottom of the first cavity. The side shape of the piston seat 14 matches the inner wall shape of the bottom of the second cavity to close the bottom of the second cavity when the locking head is engaged. The bottom of the first cavity protrudes to form a second receiving groove. The bottom of the second receiving groove is connected to the second cavity. The seat 11 is disposed in the second receiving groove. The spring 10 is sleeved on the thin plate 6 and the bottom of the spring 10 abuts against the seat 11.

[0074] In one embodiment, such as Figure 7As shown, when the pusher head 1 is in the locked state, the first thread and the second thread engage to seal the liquid transmission channel inside the pusher head 1. At this time, the side wall of the piston seat 14 is attached to the inner wall of the bottom of the second cavity to seal the bottom of the second cavity, thereby preventing the liquid inside the product from flowing out when the foam pump is installed.

[0075] Optionally, the inner diameter of the second cavity is smaller than the inner diameter of the first cavity. The base 11 can be an annular structure, with a hole in the center for the racket shaft 62 to pass through. The shape of this hole can be circular, square, or other shapes. The specific shape of the hole can be determined based on the shape of the racket shaft 62.

[0076] Optionally, the top of the piston seat 14 can be inserted into and fixed inside the racket shaft 62. The top of the piston rod 13 can be provided with an annular fixing groove, and the inside of the racket shaft 62 can be provided with an annular protrusion. The relative fixation of the racket shaft 62 and the piston seat 14 is achieved through the engagement of the annular protrusion with the fixing groove.

[0077] In one embodiment, the outer diameter of the piston seat 14 is smaller than the inner diameter of the second cavity. The piston seat 14 includes a first seat body 141 and a second seat body 142. The top of the first seat body 141 is inserted into the lever 62. The first seat body 141 can be a hollow structure, and the bottom of the first seat body 141 can have a through hole penetrating the first seat body 141. The bottom of the first seat body 141 is connected to the second seat body 142. The second seat body 142 may include a first annular groove and a second annular groove. The bottom of the first annular groove is connected to the bottom of the second annular groove. The bottom of the first seat body 141 is fixed in the first annular groove, and the inner diameter of the second annular groove is larger than the inner diameter of the first annular groove.

[0078] Optionally, the inner side of the piston 13 may surround and fit against the first seat 141, thereby forming a sealing structure through the piston 13, the first seat 141 and the second cavity.

[0079] Optionally, the pump core also includes a valve 15 and a suction tube 16. The suction tube 16 is connected to the end of the second cavity away from the first cavity, and the valve 15 is fixed in the second cavity and located at the end of the second cavity away from the first cavity.

[0080] In one embodiment, valve 15 can be a glass bead, which forms a one-way passage so that the liquid in straw 16 flows into the second chamber through the glass bead, rather than flowing out of the second chamber through the glass bead, thus preventing backflow of liquid and gas.

[0081] Optionally, the pump core may also include a pull rod 9, which is disposed inside the flap 62. The top of the pull rod 9 protrudes from the thin flap 6 and contacts the large flap 4. A movable gap is provided between the pull rod 9 and the inside of the flap 62. This movable gap allows the thin flap 6 to move relative to the pull rod 9 in the axial direction of the thin flap 6, that is, the thin flap 6 can move relative to the pull rod 9.

[0082] In one embodiment, the opening at the top of the tap 6 gradually increases in the direction away from the piston 13, and the top of the pull rod 9 is provided with an enlarged portion corresponding to the opening, the outer diameter of which corresponds to the inner diameter of the opening.

[0083] The following section will further explain the foam pump through its specific working process.

[0084] In one embodiment, the large hammer 4, the blade 5, and the small hammer 6 are connected together, and the intake and exhaust are accomplished by the axial reciprocating motion of the three components and the cylinder 12. A spring 10 is fitted onto the small hammer 6, with its lower end supported by a seat 11, and its upper end abutting against the bottom of the support platform 61 of the small hammer 6. The lower end of the small hammer 6 is connected to a piston seat 14, and a piston 13 is fitted onto the piston seat 14. The piston 13 can slide axially up and down relative to the piston seat 14 and the small hammer 6. Under external force, the pusher head 1 moves towards the large hammer 4 and the small hammer 6. During this movement, the small hammer 6 and the large hammer 4 follow suit. The small hammer 6 causes the piston seat 14 to move downwards a certain distance relative to the corresponding piston 13. This downward movement is sufficient to disengage the piston seat 14 from the sealed connection with the piston 13. After the external force is removed, the rebound force of the spring 10 drives the thin plate 6, the large plate 4, and the pressing head 1 to move upward. During the movement, the piston seat 14 moves upward a certain distance first, enough for the piston seat 14 to move towards the piston 13 until the piston seat 14 and the piston 13 are in a sealed connection. A valve 15 for controlling the passage of air is provided in the inner cavity at the lower end of the cylinder 12. The cylinder 12 located below the valve 15 is connected to the suction tube 16, through which external liquid is drawn.
