Description

Technical Field

[0001] This invention relates to the field of emulsion pump technology, and more specifically, to an emulsion pump with a large spray volume and a left-right locking anti-opening design. Background Technology

[0002] Emulsion pumps are typically installed at the opening of a container and are used by the user to manually pump liquids such as emulsions out of the container for use. Although users can adjust the spray volume by pressing down to different degrees as needed, in practice, users usually press all the way down, resulting in excessive emulsion being sprayed out and wasted.

[0003] Therefore, it is necessary to provide a high-volume, left-right locking emulsion pump to solve the above problems.

[0004] new content

[0005] Based on the aforementioned problems in the existing technology, the purpose of this application is to provide a high-volume, left-right locking anti-opening emulsion pump to achieve the effect of controlling the spray volume.

[0006] The technical solution adopted by this application to solve its technical problem is: a high-volume, left-right locking anti-opening emulsion pump, including a storage tube, a suction tube fixedly installed at the lower end of the storage tube, a pump tube movably arranged inside the storage tube, a pump cover installed at the upper end of the pump tube extending out of the storage tube, a limit plate fixed to the inner wall of the storage tube, the limit plate dividing the inside of the storage tube into upper and lower layers, wherein the lower layer is a storage layer and the upper layer is a movable layer, the upper end of the storage layer is connected to the lower end of the storage layer, and the pump tube... It consists of three layers: a lower tube located within the storage layer, a middle tube located within the movable layer, and an upper tube extending beyond the storage tube. A reset plate is provided on the outer wall of the middle tube, and a reset elastic element is provided between the reset plate and the bottom of the movable layer. A movable plug is threaded onto the lower tube, and the outer wall of the movable plug is adapted to the inner wall of the storage layer. A discharge pipe is fixed to one side of the pump cover, and a sleeve is fixed to the lower end of the pump cover. The upper end of the upper tube is sleeved on the sleeve, and the upper end of the sleeve is connected to the discharge pipe.

[0007] Furthermore, a suction port is provided at the lower end of the storage layer, a suction baffle is fixed to the inner wall of the suction port, a suction rod is fixed to the upper end of the suction port, a suction blocking ball is provided between the suction baffle and the suction rod, and the upper end of the suction pipe is connected to the lower end of the suction port.

[0008] Furthermore, a limiting tube is fixed to the inner wall of the lower end of the lower tube, and several discharge baffles are fixed to the inner wall of the lower tube. The discharge baffles are located on the upper side of the limiting tube, and a discharge blocking ball is provided between the discharge baffles and the limiting tube.

[0009] Furthermore, a fixing cap is fixed to the upper edge of the active layer.

[0010] Furthermore, an elastic block is fixed to the lower end of the limiting tube after it extends out of the lower tube.

[0011] Furthermore, the cross-section of the storage layer is rectangular, the central tube is cylindrical, the reset plate is sleeved on the central tube, and a fixing plate is fixed to the upper end of the central tube.

[0012] Furthermore, the upper tube has a rectangular cross-section, and a chuck is fitted onto the upper tube, which is rotatably connected to the upper end of the storage tube.

[0013] Furthermore, the bottom edge of the chuck is circumferentially distributed with several slots, and the upper end of the storage tube is distributed with several block slots corresponding to the slots. Each block slot is provided with a block, and the bottom of each block is fixed with a block elastic element.

[0014] Furthermore, one end of the slot extends to the outside of the chuck, a chuck sleeve is movably fitted on the chuck, a movable groove is provided at the bottom of the side wall of the chuck, a number of external teeth are evenly distributed at the bottom of the movable groove, the height of the external teeth is lower than the height of the slot, a number of internal teeth are evenly distributed at the bottom of the inner side of the chuck sleeve, the internal teeth are located in the movable groove, and the distance between the bottom of the external teeth and the bottom of the movable groove is greater than the height of the internal teeth.

[0015] Furthermore, a threaded tube is fixed at the center of the top of the chuck sleeve, the upper tube is located inside the threaded tube, the outer wall of the threaded tube is provided with external threads, the inner side of the pump cover is provided with internal threads corresponding to the external threads, and a top block is provided at the center of the bottom of the pump cover.

[0016] The beneficial effects of this invention are:

[0017] When the pump tube and the movable plug rotate relative to each other, the movable plug will move up and down relative to the lower tube. The limiting plate blocks the movable plug, so when the reset elastic element drives the pump tube to move upward, the movable plug is ultimately limited by the limiting plate. That is, after each reset, the position of the movable plug is the same. After the movable plug and the upper tube move, the distance from the bottom of the lower tube to the storage layer decreases after the reset. As a result, when the user presses the pump cover, the descent distance of the pump tube and the movable plug also changes.

[0018] When the movable stopper moves upward relative to the lower tube, the length of the lower tube below the movable stopper increases. When the user presses the pump cap, the descent distance between the pump tube and the movable stopper shortens, resulting in a decrease in the amount of emulsion squeezed out. Conversely, when the movable stopper moves downward relative to the lower tube, the length of the lower tube below the movable stopper shortens. When the user presses the pump cap, the descent distance between the pump tube and the movable stopper increases, resulting in an increase in the amount of emulsion squeezed out. In summary, this achieves the effect of controlling the amount of emulsion squeezed out with each press of the emulsion pump. Attached Figure Description

[0037] Example 1:

[0038] This embodiment illustrates the structure and working principle of an emulsion pump, specifically:

[0039] like Figure 1-6 As shown, this application provides a high-volume, left-right locking anti-opening emulsion pump, including a storage pipe 1, a suction pipe 2 fixedly installed at the lower end of the storage pipe 1, a fixed cover 3 fixedly installed at the upper edge of the storage pipe 1, a pump pipe 4 movably arranged inside the storage pipe 1, and a pump cover 5 installed at the upper end of the pump pipe 4 after it extends out of the storage pipe 1.

[0040] A limiting plate 11 is fixed to the inner wall of the storage tube 1. The limiting plate 11 divides the interior of the storage tube 1 into upper and lower layers, with the lower layer being the storage layer 12 and the upper layer being the movable layer 13. The upper end of the storage layer 12 is connected to the lower end of the storage layer 13.

[0041] A suction port 121 is provided at the lower end of the storage layer 12. An inclined suction baffle 122 is fixed to the inner wall of the suction port 121. A suction baffle 123 is fixed to the upper end of the suction port 121. A suction blocking ball 124 is provided between the suction baffle 122 and the suction baffle 123. The upper end of the suction pipe 2 is connected to the lower end of the suction port 121.

[0042] The pump pipe 4 is divided into three layers: the lower pipe 41 is located in the storage layer 12, the middle pipe 42 is located in the active layer 13, and the upper pipe 43 extends out of the storage pipe 1.

[0043] A movable plug 6 is installed on the outer wall of the lower pipe 41, and the outer wall of the movable plug 6 is adapted to the inner wall of the storage layer 12.

[0044] A limiting tube 411 is fixed to the inner wall of the lower end of the lower tube 41, and several discharge baffles 412 are fixed to the inner wall of the lower tube 41. The discharge baffles 412 are located on the upper side of the limiting tube 411, and a discharge blocking ball 413 is provided between the discharge baffles 412 and the limiting tube 411.

[0045] A reset plate 421 is provided on the outer wall of the middle tube 42, and a reset elastic element 422 is provided between the reset plate 421 and the bottom of the movable layer 13. In this embodiment, the reset elastic element 422 is a spring.

[0046] A discharge pipe 51 is fixed on one side of the pump cover 5, and a sleeve 52 is fixed at the lower end of the pump cover 5. The upper end of the upper pipe 43 is sleeved on the sleeve 52, and the upper end of the sleeve 52 is connected to the discharge pipe 51.

[0047] In this embodiment, when the emulsion moves upward at the suction port 121, it pushes open the suction plug 124, allowing the emulsion to move upward within the suction port 121. When the emulsion moves upward at the suction port 121, it pushes the suction plug 124 downward, causing the suction plug 124 to work with the suction baffle 122 to block the suction port 121, thus preventing the emulsion from moving downward within the suction port 121. In summary, this achieves the effect of allowing the emulsion to move upward only within the suction port 121. Similarly, the discharge plug 413 allows the emulsion to move upward only within the pump pipe 4.

[0048] The suction baffle 123 and the discharge baffle 412 are used to prevent the suction ball 124 and the discharge ball 413 from being pushed too far away by the emulsion, making it difficult to block the suction port 121 and the pump pipe 4.

[0049] The reset elastic element 422 pushes the reset plate 421 through its own elasticity, causing the reset plate 421 to move the pump pipe 4 upward, thereby keeping the upper pipe 43 extended out of the storage pipe 1.

[0050] Understandably, the retaining cap 3 is used to secure the bottle opening of the external lotion bottle (not shown).

[0051] During use, the user needs the pump cover 5. The pump cover 5 will drive the movable plug 6 to move downward in the storage layer 12 through the pump pipe 4, thereby generating positive pressure in the storage layer 12. At this time, the suction port 121 is blocked by the suction plug ball 124, while the discharge pipe 4 is opened by the discharge plug ball 413. This positive pressure will push the emulsion under the movable plug 6 into the pump pipe 4, and then into the sleeve 52 along the pump pipe 4, and spray it out from the discharge pipe 51.

[0052] After the user releases the pump cover 5, the reset elastic element 422, through the reset plate 421, drives the pump tube 4 to reset. During this process, the movable plug 6 moves upward within the storage layer 12, thereby generating negative pressure in the storage layer 12. At this time, the suction port 121 is opened by the suction plug ball 124, while the pump outlet 4 is blocked by the discharge plug ball 413, so that the negative pressure will draw the emulsion in the emulsion bottle into the storage layer 12 through the suction port 121 and the suction tube 2.

[0053] The lower end of the limiting tube 411 extends out of the lower tube 41 and is fixed with an elastic block 414. The elastic block 414 is used to mitigate the impact when the lower end of the lower tube 41 and the lower end of the storage layer 12 collide, so as to avoid damage to the lower tube 41 or the storage layer 12.

[0054] Since the upper end of the upper pipe 43 is sleeved on the sleeve 52, the user can change the orientation of the discharge pipe 51 by rotating the pump cover 5.

[0055] Example 2:

[0056] This embodiment includes all the structures in Embodiment 1, and adds the following structures to Embodiment 1:

[0057] The storage layer 12 has a rectangular cross-section, and the lower tube 41 is threadedly connected to the movable plug 6. When the pump tube 4 and the movable plug 6 rotate relative to each other, the movable plug 6 will move up and down relative to the lower tube 41. The limiting plate 11 blocks the movable plug 6, so that when the reset elastic element 422 drives the pump tube 4 to move upward, the movable plug 6 is ultimately limited by the limiting plate 11, that is, after each reset, the position of the movable plug 6 is the same. After the movable plug 6 and the upper tube 43 move, the distance from the bottom end of the lower tube 41 to the storage layer 12 decreases after reset, thus changing the descent distance of the pump tube 4 and the movable plug 6 when the user presses the pump cover 5.

[0058] When the movable plug 6 moves upward relative to the lower tube 41, the length of the lower tube 41 below the movable plug 6 increases. When the user presses the pump cover 5, the descent distance between the pump tube 4 and the movable plug 6 shortens, resulting in a decrease in the amount of emulsion squeezed out. Conversely, when the movable plug 6 moves downward relative to the lower tube 41, the length of the lower tube 41 below the movable plug 6 shortens. When the user presses the pump cover 5, the descent distance between the pump tube 4 and the movable plug 6 increases, resulting in an increase in the amount of emulsion squeezed out. In summary, this achieves the effect of controlling the amount of emulsion squeezed out with each press of the emulsion pump.

[0059] The central tube 42 is cylindrical, and a reset plate 421 is fitted onto the central tube 42. A fixing plate 423 is fixed to the upper end of the central tube 42. By fitting the reset plate 421 onto the central tube 42, relative rotation between the reset plate 421 and the pump tube 4 is possible. This prevents the pump tube 4 from rotating and causing the reset plate 421 to rotate the reset elastic element 422, thus avoiding torsional damage to the reset elastic element 422. When the reset elastic element 422 pushes the reset plate 421, the reset plate 421 can push the fixing plate 423, thereby resetting the pump tube 4.

[0060] The upper tube 43 has a rectangular cross-section, and a chuck 431 is fitted onto the upper tube 43. The chuck 431 is rotatably connected to the upper end of the storage tube 1. Since the upper tube 43 has a rectangular cross-section, the user can rotate the pump tube 4 by rotating the chuck 431, thereby adjusting the positional relationship between the pump tube 4 and the movable plug 6, and thus adjusting the spray volume of the emulsion pump.

[0061] The bottom edge of the chuck 431 has several slots 432 distributed circumferentially. The upper end of the storage tube 1 has several block slots 131 corresponding to the positions of the slots 432. Each block slot 131 contains a block 132, and the bottom of each block 132 is fixed with a block elastic element 133. In this embodiment, the block elastic element 133 is a spring. Due to the elasticity of the block elastic element 133, the top of the block 132 is pushed out of the block slot 131 and engaged in the slot 432, causing the block 132 to engage with the chuck 431 through the slot 432, thereby preventing the chuck 431 and pump tube 4 from rotating and avoiding accidental rotation of the pump tube 4 that could cause a change in spray volume.

[0062] One end of the slot 432 extends outward from the chuck 431, and a chuck sleeve 7 is movably fitted onto the chuck 431. A movable groove 433 is provided at the bottom of the side wall of the chuck 431, and several external teeth 434 are evenly distributed at the bottom of the movable groove 433. The height of the external teeth 434 is lower than the height of the slot 432. Several internal teeth 71 are evenly distributed at the bottom of the inner side of the chuck sleeve 7, and the internal teeth 71 are located within the movable groove 433. The distance between the bottom of the external teeth 434 and the bottom of the movable groove 433 is greater than the height of the internal teeth 71.

[0063] Under normal circumstances, when the elastic element 133 of the chuck block lifts the chuck block 132, it will also lift the chuck sleeve 7. Since the height of the outer tooth 434 is lower than the height of the chuck groove 432, and the distance between the bottom of the outer tooth 434 and the bottom of the movable groove 433 is greater than the height of the inner tooth 71, the outer tooth 434 and the inner tooth 71 are separated at this time, allowing the chuck sleeve 7 to rotate freely, and even if the chuck sleeve 7 rotates, it will not cause the chuck 431 to rotate.

[0064] like Figure 5As shown, when the user needs to adjust the spray volume, the chuck sleeve 7 must first be pressed down, allowing the chuck sleeve 7 to press the locking block 132 into the locking block groove 131. At this time, the chuck 431 is no longer restricted from rotating by the locking block 132, and the inner tooth 71 engages with the outer tooth 434. When the user rotates the chuck sleeve 7 while it is pressed down, the chuck sleeve 7 can drive the chuck 431 to rotate through the inner tooth 71 and the outer tooth 434. The chuck 431 then drives the pump pipe 4 to rotate, thereby adjusting the spray volume.

[0065] The top of the movable groove 433 can restrict the chuck sleeve 7 through the internal teeth 71, preventing the chuck sleeve 7 from separating from the chuck 431.

[0066] A threaded tube 72 is fixed at the center of the top of the chuck sleeve 7. An upper tube 43 is located inside the threaded tube 72. External threads 73 are provided on the inner and outer walls of the threaded tube 72. An internal thread 53 corresponding to the external threads 73 is provided on the inner side of the pump cover 5. A top block 54 is provided at the center of the bottom of the pump cover 5. During production, the operator can press down and then rotate the pump cover 5 to thread it onto the chuck sleeve 7 using the external threads 73 and the internal threads 53. Figure 6 As shown, during the tightening process between the pump cover 5 and the chuck sleeve 7, the overall size of the emulsion pump is reduced, making it easier to transport. At the same time, the top block 54 passes through the inside of the threaded tube 72 and presses against the upper side of the chuck 431. With the threaded fixation between the pump cover 5 and the chuck sleeve 7, the chuck sleeve 7 can be prevented from being pressed down, keeping the chuck 431 in the state of being held by the locking block 132. This prevents the pump tube 4 from being rotated, thus avoiding the pump tube 4 from being rotated during transportation. This also prevents the movable plug 6 from being displaced downwards during transportation, which would cause the emulsion to be squeezed out and wasted.
