Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0021] The embodiments of this application will be further described in detail below with reference to the accompanying drawings.
[0022] This application provides an all-plastic push-button pump with a plastic bayonet bottle design. The bottle lock and the addition of a middle sleeve can achieve simultaneous filling, effectively improving production efficiency.
[0023] The embodiments of this application will be further described in detail below with reference to the accompanying drawings.
[0024] See Figures 1-25 As shown, this application embodiment provides an all-plastic push-button pump, which includes a plastic clip 7, an upper pump rod 4, a piston 9, and a bottle 14. The plastic clip 7 includes: First cylindrical structure 70; A second cylindrical structure 71 is spaced out and sleeved around the first cylindrical structure 70; A third cylindrical structure 72 is spaced around the second cylindrical structure 71; Multiple arc-shaped plate structures 73 are symmetrically arranged at the bottom end of the third cylindrical structure 72, and the inner wall of the arc-shaped plate structure 73 is provided with claw buckles 730. The top end of the first cylindrical structure 70 is connected to the top end of the second cylindrical structure 71 by a first annular connector 74; The top end of the second cylindrical structure 71 is provided with a first limiting cylindrical structure 75, and the top end of the first limiting cylindrical structure 75 is higher than the top end of the first cylindrical structure 70 and the top surface of the first annular connector 74. The bottom end of the second cylindrical structure 71 is connected to the top end of the third cylindrical structure 72 by a second annular connector 76; The top end of the third cylindrical structure 72 is provided with a second limiting cylindrical structure 77, the top end of the second limiting cylindrical structure 77 being higher than the top end of the third cylindrical structure 72 and the top surface of the second annular connector 76; wherein, The center of the first cylindrical structure 70 forms a first channel 78 for the snap-fit component to allow the upper pump rod 4 and piston 9 to move; The plurality of said arc-shaped plate structures 73 form a first snap-fit space 79 for snap-fitting the top opening of the bottle 14.
[0025] It should be noted that the plastic bayonet 7 is integrated with the locking cover used in the existing technology, so that the plastic bayonet 7 can directly cooperate with the pump chamber 11, which can reduce one part and greatly save costs. Furthermore, the outer edge of the plastic buckle 7 is provided with a middle sleeve guide slope structure 770, which acts to fit tightly with the middle sleeve and prevent pre-installation from loosening.
[0026] In this embodiment, a plastic bayonet bottle design is adopted, and the bottle lock with a middle sleeve can achieve simultaneous filling, effectively improving production efficiency.
[0027] Furthermore, the integrated design of the upper pump rod and piston spring, along with the integrated design of the plastic buckle and locking cover, greatly reduces the space occupied and makes the product look simpler and more beautiful.
[0028] The embodiments of this application adopt a metal-free glass design, and all components, including springs, are made of plastic. The structure is simpler and there are fewer parts, which can effectively solve the problem of difficult metal-plastic sorting during product recycling, making the product more environmentally friendly.
[0029] Furthermore, the first cylindrical structure 70, the second cylindrical structure 71, the third cylindrical structure 72, the arc-shaped plate structure 73, the claw buckle 730, the first annular connector 74, the first limiting cylindrical structure 75, the second annular connector 76, and the second limiting cylindrical structure 77 are integrally formed.
[0030] Furthermore, the top of the outer wall of the second limiting cylindrical structure 77 is provided with a middle sleeve guide slope structure 770.
[0031] Furthermore, the gripper buckle 730 is a trapezoidal buckle; The number of the arc-shaped plate structure 73 is 8; The number of gripper clips 730 is 2.
[0032] The gripper buckle 730 fits the bottle lip shape better when acting on the bottle mouth; two gripper buckles 730 are distributed on each of the arc-shaped plate structures 73. The gripper buckle 730 is trapezoidal and acts with a reaction force to fasten the bottle mouth, making it difficult for the plastic locking piece 7 to slip out; its gripper feature is that during filling assembly, the plastic locking piece 7 can be pre-assembled with the bottle 14, and the gripper locks the bottle 14, so that the plastic locking piece 7 remains vertical during the operation and shaking of the production assembly line, which is convenient for locking the bottle.
[0033] Furthermore, a plastic spring 5 is fitted onto the upper pump rod 4; The spring 5 is provided with a first limiting plate 50, a second limiting plate 51 and a third limiting plate 52 from top to bottom; The first limiting plate 50, the second limiting plate 51 and the third limiting plate 52 are all provided with limiting plate through holes for the upper pump rod 4 to pass through; A first spring assembly 53 is provided between the first limiting plate 50 and the second limiting plate 51; A second spring assembly 54 is provided between the second limiting plate 51 and the third limiting plate 52; The first limiting plate 50, the second limiting plate 51, the third limiting plate 52, the first spring assembly 53, and the second spring assembly 54 are integrally formed; The top sidewall of the upper pump rod 4 is surrounded by an upper pump rod annular limiting plate 40, and the bottom edge of the upper pump rod annular limiting plate 40 is surrounded by an upper pump rod cylindrical limiting member 41. The bottom end of the upper pump rod 4 passes through the center of the limiting plate through hole, the first spring assembly 53 and the second spring assembly 54; The first limiting plate 50 is restricted by the upper pump rod cylindrical limiting member 41 to the bottom surface of the upper pump rod annular limiting plate 40; The third limiting plate 52 is restricted by the first limiting cylindrical structure 75 to the top surface of the first annular connector 74.
[0034] Furthermore, both the first spring assembly 53 and the second spring assembly 54 include two arc-shaped support bars 55 arranged in opposite directions; The two arc-shaped support bars 55 of the first spring assembly 53 are mirror images of the two arc-shaped support bars 55 of the second spring assembly 54.
[0035] Specifically, spring 5 uses plastic instead of traditional metal, making it more environmentally friendly.
[0036] Furthermore, the two arc-shaped support bars 55 of the first spring assembly 53 and the two arc-shaped support bars 55 of the second spring assembly 54 are distributed in a mirror image. This structure allows it to bend in an arc during compression, preventing it from folding and losing its function. The bending arc caused by compression, combined with the reaction force generated by the material's toughness, allows it to stretch and return to its original position, achieving the characteristic of being able to be repeatedly pressed like a conventional metal spring.
[0037] Furthermore, the all-plastic push-button pump also includes a lower pump rod 10: A piston spring 42 is fitted at the bottom of the upper pump rod 4; The piston spring 42 is provided with a first piston spring plate 420, a second piston spring plate 421 and a third piston spring plate 422 from top to bottom; The first piston spring plate 420, the second piston spring plate 421 and the third piston spring plate 422 are all provided with piston spring plate through holes for the lower pump rod 10 to pass through; A first piston spring assembly 423 is provided between the first piston spring plate 420 and the second piston spring plate 421; A second piston spring assembly 424 is provided between the second piston spring plate 421 and the third piston spring plate 422; Both the first piston spring assembly 423 and the second piston spring assembly 424 include two piston spring arc-shaped support bars 425 arranged in opposite directions; The two piston spring arc-shaped support bars 425 of the first piston spring assembly 423 are mirror images of the two piston spring arc-shaped support bars 425 of the second piston spring assembly 424; The top of the first piston spring plate 420 abuts against the bottom surface of the third limiting plate 52; The bottom of the third piston spring plate 422 abuts against the top of the piston 9.
[0038] Furthermore, the two piston spring arc-shaped support bars 425 of the first piston spring assembly 423 and the two piston spring arc-shaped support bars 425 of the second piston spring assembly 424 are mirror images of each other. This structure allows the spring to bend in an arc during compression, preventing it from folding and losing its function. The bending arc caused by compression and the reaction force generated by the material's toughness allow it to stretch and return to its original position, achieving the characteristic of being able to be repeatedly pressed like a conventional metal spring.
[0039] It should be noted that the spring 5 and piston spring 42 are integrated into a single design using PP material, eliminating the metal material used in the previous piston short spring, which facilitates material recycling.
[0040] Furthermore, the all-plastic push pump also includes a push cap 1, a misting point 2, a push nozzle 3, a middle sleeve 6, a lower pump rod 10, a pump chamber 11, a one-way valve 12, and a liquid inlet tube 13; The mist droplet 2 is fitted at the opening of the spray channel 30 of the nozzle 3, the mist droplet 2 and the nozzle 3 are disposed inside the cap 1, and the mist droplet 2 is locked inside the spray opening 15 of the cap 1; The top of the upper pump rod 4 is connected to the bottom of the nozzle 3; The lower pump rod 10 passes through the interior of the upper pump rod 4 from the bottom end of the upper pump rod 4 and is engaged with the bottom of the nozzle 3; The piston 9 is engaged between the upper pump rod 4 and the lower pump rod 10. The middle sleeve 6 is fitted onto the outer wall of the cap 1 and the third cylindrical structure 72, forming a protective space. The one-way valve 12 is located at the opening at the bottom end of the pump chamber 11 and is connected to the liquid inlet pipe 13.
[0041] Furthermore, the spraying end of the mist dot 2 is smoothly connected to the area on the cap 1 located around the spray opening 15.
[0042] Furthermore, an annular gasket 8 is fitted on the top side wall of the pump chamber 11, and the top surface of the gasket 8 abuts against the bottom surface of the second annular connector 76.
[0043] In specific implementation, the technical solution based on the embodiments of this application is as follows: The all-plastic press pump consists of a press cap 1, a misting point 2, a press nozzle 3, an upper pump rod 4, a spring 5, a middle sleeve 6, a plastic buckle 7, a gasket 8, a piston 9, a lower pump rod 10, a pump chamber 11, a one-way valve 12, and a liquid inlet tube 13, and is mounted on a bottle 14.
[0044] The cap 1 is made of plastic and, when used with the nozzle 3, can solve the problem of uneven appearance of the nozzle.
[0045] The nozzle 3 channel fits tightly with the conical surface A of the mist dot 2 to form a seal, and after assembly, it is flush with the spray hole B of the cap 1, making it more aesthetically pleasing.
[0046] The nozzle 3 is equipped with a sealing ring E that fits tightly with the sealing ring of the upper pump rod 4 to form a seal.
[0047] The upper pump rod 4 cooperates with the spring 5, and the limiting structure D can fix the spring 5 to prevent it from sliding during operation, thereby keeping it vertical and making the force more uniform. The lower end G of the upper pump rod 4 is a spring design, which is combined with the piston spring 42, making it simpler and reducing assembly difficulty.
[0048] The lower pump rod 10 is fitted with an inverted buckle at position F to ensure a tight and secure engagement between the upper and lower pump rods.
[0049] The plastic buckle 7 and the locking cover are integrated into one piece, which saves on parts and assembly space; After being assembled into a valve needle, it is assembled with the pump chamber 11 to form a pump body, making assembly simpler and easier. The plastic fastener 7 is provided with an inverted H at the pump chamber 11 position, which allows the plastic fastener 7 to fit tightly with the pump chamber 11. Furthermore, the inner diameter of the plastic fastener 7 is interference-fitted with the outer diameter of the pump chamber 11 to form a seal.
[0050] The plastic clip 7 is equipped with a claw clip I for fixing the bottle 14, which is convenient for high-filling applications. At the same time, a gasket 8 is provided at the sealing point between the plastic clip 7 and the bottle 14, which makes the seal more stable and more compatible with various bottle openings.
[0051] The pump chamber 11 is matched with the one-way valve 12. The stepped plane of the pump chamber 11 is matched with the central column plane of the one-way valve 12 to form a seal, which replaces the conventional pump ball seal. The one-way valve matching seal is more stable and timely, avoiding back leakage.
[0052] The user can brake the nozzle 3 assembly, causing the valve needle to move downwards to the limit step K of the pump chamber 11. The piston 9 stops moving, and the valve needle continues to move downwards, opening the channel. The internal pressure gas is released to the outside of the pump head through the exhaust groove along the nozzle 3. When returning upwards, the piston is pushed by the force of the upper pump rod 4 spring to close the exhaust groove channel first. The valve needle returns to its original position due to the force of the spring 5. The space of the storage chamber J increases and the internal pressure decreases, creating a pressure difference that allows the contents to flow from the liquid inlet tube 13 to the storage chamber J. When the same action is repeated, the contents in the storage chamber J forcibly open the channel, leading to the cyclone groove of the nozzle and all the way to the mist hole. Under the action of centrifugal force, the contents are atomized.
