Description

A high-efficiency all-plastic perfume pump Technical Field

[0001] The present invention relates to the technical field of perfume pumps, and in particular to a high-efficiency all-plastic perfume pump. Background Art

[0002] Currently, there are numerous micro-sprayers on the market. These sprayers atomize and spray the liquid in a container by pressing a lever or cap. Their operating principle is as follows: a piston moves within a pump body, causing gas to flow and reduce pressure inside the pump body, while maintaining pressure outside the pump body. This creates a pressure differential between the inside and outside of the pump body, which directs the liquid out of the pump body. When the liquid encounters the high-speed airflow, it instantly atomizes. This utilizes Bernoulli's principle: for the same fluid, high flow rate results in low pressure, while low flow rate results in high pressure. These sprayers are widely used in fields such as gardening, hair salons, and beauty salons. Some micro-sprayers with push-button caps are primarily used in the beauty industry for perfume spraying, or as perfume pumps.

[0003] In order to prevent the metal spring in the pump body from chemically reacting with the liquid perfume, thereby affecting the effect of the perfume and the spring, some perfume pumps adopt an external spring structure. However, for foreign markets, especially the European and American markets, it is difficult to meet the environmental protection control standards in these places; and a perfume pump contains plastic, metal and glass parts at the same time, which need to be disassembled and sorted for recycling during recycling, which is not conducive to product recycling.

[0028] The above and other technical features and advantages of the present invention are described in more detail below with reference to the accompanying drawings.

[0029] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0030] It should be noted that, in the description of the present invention, terms such as "up", "down", "left", "right", "inside", and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0031] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0032] As shown in Figures 1-9, a high-efficiency all-plastic perfume pump includes a pump chamber 1, a liquid inlet 2 is provided at the lower end of the pump chamber 1, a one-way valve 3 capable of closing the liquid inlet 2 is provided in the lower part of the pump chamber 1, a lower pump rod 4 is provided in the pump chamber 1, a feed port 5 capable of connecting the internal flow channel of the lower pump rod 4 with the inner cavity of the pump chamber 1 is provided on the lower outer wall of the lower pump rod 4, an upper pump rod 6 is inserted into the lower pump rod 4, a piston 7 is sleeved on the outer wall of the lower pump rod 4, an elastomer 8 is sleeved on the outer wall of the lower pump rod 4 between the piston 7 and the upper pump rod 6, a tapered portion 9 is provided on the upper outer wall of the upper pump rod 6, a tapered plastic block 10 capable of resetting the upper pump rod 6 is sleeved on the upper pump rod 6 at the upper end of the pump chamber 1, and a spray head 11 is connected to the upper pump rod 6.

[0033] The present invention uses the elastic body 8 disposed between the piston 7 and the upper pump rod 6, and the tapered portion 9 and tapered plastic block 10 on the outer wall of the upper pump rod to cooperate with each other, so that the upper pump rod 6, the lower pump rod 4, and the piston 7 can automatically reset, effectively increasing the explosive force and making the whole body sprayable. It is easy to use and efficient.

[0034] The conical plastic block 10 of the present invention includes a conical body 101, and a notch 102 is provided on one side of the conical body 101 to facilitate the deformation of the conical body 101. In the present invention, the conical portion 9 gradually shrinks from top to bottom, and the conical plastic block 10 it controls gradually expands from top to bottom. When the nozzle 11 is pressed down by an external force, the upper pump rod 6 moves downward, and the conical plastic block 10 is squeezed open. On the contrary, when the nozzle 11 exerts an external force, the conical plastic block 10 uses its own contractility to achieve the effect of a spring. The structure is simple and ingenious, and it can delay the service life while ensuring elastic force. In the present invention, a limiting convex ring 62 is provided on the outer wall of the upper end of the upper pump rod 6. The limiting convex ring 62 of the present invention effectively prevents the conical plastic block 10 from detaching from the upper pump rod 6 from above.

[0035] The present invention provides an integrated bayonet lock cover 12 at the upper end of the pump chamber 1, and a snap ring 13 is provided on the outer wall of the upper end of the pump chamber 1.

A connecting platform 126 is provided on the inner side of the junction of the extension pipe 124 and the connecting pipe 122, and a central plug-in tube 127 is provided on the inner side of the connecting platform 126. An accommodating ring groove 129 is provided between the central plug-in tube 127 and the extension pipe 124. The snap ring 13 is clamped in the accommodating ring groove 129, and an elastic snap-fit ​​portion 128 that cooperates with the bottle mouth 14 of the perfume bottle is provided on the outer periphery of the cover body 121. The elastic snap-fit ​​portion 128 includes a sleeve 1281 integrally formed with the cover 121. A snap-fitting protrusion 1282 is provided on the inner wall of the lower end of the sleeve 1281.

A plastic sleeve 15 is provided over the sleeve 1281, which presses the snap-fitting protrusion 1282 into the connecting groove 141. A sealing protrusion 142 is provided at the upper end of the perfume bottle mouth 14, and a sealing gasket 16 is provided on the outer wall of the connecting tube 122. The lower end of the sealing gasket 16 presses against the perfume bottle mouth 14, while the upper end of the sealing gasket 16 presses against the cover 121.

[0036] The annular snap-fit ​​portion 123 of the integrated bayonet lock cover 12 of the present invention is snap-fitted onto the upper end of the pump chamber 1. At this time, the snap-fit ​​ring 13 is snap-fitted into the accommodating ring groove 129. To further enhance the connection stability between the integrated bayonet lock cover 12 and the pump chamber 1, a positioning snap ring is provided on the side of the central plug-in tube 127 facing the inner wall of the pump chamber 1. A positioning ring groove is provided at a position corresponding to the positioning snap ring in the pump chamber 1. The positioning snap ring is snap-fitted into the positioning ring groove. After the integrated bayonet lock cover 12 and the pump chamber 1 are assembled, a sealing gasket 16 is provided within the cover body 1. To prevent the sealing gasket 16 from detaching from the connecting tube 122, an outer protrusion is provided on the upper portion of the connecting tube 122. The sealing gasket 16 is snap-fitted between the outer protrusion and the lower end surface of the cover body 1. Insert the assembled integrated bayonet lock cover 12 and the pump chamber 1 into the bottle mouth 14 of the perfume bottle, and then insert the middle sleeve 15 from top to bottom. After assembly, the snap-fit ​​convex ring 1282 is pressed tightly into the connecting ring groove 141, and the connection is firm, safe and reliable.

The bowl-shaped elastic portion 82 of the present invention can be a continuous bowl shape, or it can be composed of multiple arc-shaped bowl-shaped elastic portions.

[0038] The pump chamber 1 of the present invention includes a pump body 1001, a limiting step 1002 being provided on the lower inner wall of the pump body 1001, a liquid inlet pipe 1003 being provided in the middle of the lower end of the pump body 1001, a liquid inlet port 2 being provided on the inner wall of the pump body 1001 above the liquid inlet pipe 1003, a valve port 1004 being provided in the pump body 1001 above the liquid inlet port 2, and a one-way valve 31 being provided to seal the valve port 1004. The outer periphery of the sealing portion 31 is connected to a limiting ring 33 via a connecting portion 32, a liquid guide port 34 being provided on the connecting portion 32, and a dynamic seal being formed between the outer wall of the limiting ring 33 and the inner wall of the lower end of the pump body 1001. In the present invention, a liquid guide pipe 1005 is inserted into the liquid inlet pipe 1003. The one-way valve 3 of the present invention does not need to be distinguished by direction, making it easy to use.

[0039] The function of the limiting step 1002 in the present invention is to separate the pump rod 4 under the piston 7, thereby opening the feed port 5. In the present invention, a limiting convex portion is provided in the lower part of the pump body 1001 to prevent the limiting ring 33 from separating from the lower part of the pump body 1001.

[0040] The present invention provides an air exchange hole 17 on the outer wall of the middle portion of the pump chamber 1. Referring to Figures 7-8, during the movement of the upper pump rod and the lower pump rod, the direction of the air inside the pump chamber 1 is shown by the arrows.

[0041] In the present invention, a feeding rubber cap 18 is provided on the outer cover of the nozzle 11 .

[0042] In the present invention, a connecting ring 41 is provided at the lower end of the lower pump rod 4. An annular groove 42 is provided on the upper end surface of the connecting ring 41. The lower pump rod 4 gradually tapers from bottom to top, forming a certain taper. The piston 7 of the present invention includes a center seat 71 with a tapered hole disposed therein. When the lower end of the center seat 71 is inserted into the annular groove 42, the feed port 5 is sealed. The center seat 71 is sleeved onto the outer wall of the lower pump rod 4. An elastic piston portion 73 is provided on the outer wall of the center seat 71 via the annular connecting ring 72. The elastic piston portion 73 dynamically seals against the inner wall of the pump body 1001.

[0043] In the present invention, a buckle position 63 is provided in the upper pump rod 6 , and a buckle groove 43 is provided at a position of the lower pump rod 4 corresponding to the buckle position, and the buckle position 63 is locked in the buckle groove 43 .

[0044] The present invention provides a V-shaped extrusion block on the upper outer wall of the upper pump rod 6 that can squeeze open the conical plastic block 10. The V-shaped extrusion block is movably disposed within the notch 102. The present invention utilizes the conical portion of the upper pump rod and the V-shaped extrusion block to squeeze open the conical plastic block 10. The conical plastic block 10 then contracts by utilizing its own strength and contractility to achieve a spring effect. In addition, the V-shaped extrusion block cooperates with the notch 102 on the conical plastic block 10 to provide a good guiding effect.

[0045] The working principle of the present invention is as follows: In the initial state, the one-way valve 3 closes the liquid inlet 2, and the nozzle 11 is in the highest position. When the nozzle 11 is subjected to a downward external force, the nozzle 11 drives the upper pump rod 6, the lower pump rod 4, the elastic body 8, and the piston 7 to move downward synchronously. At the same time, the tapered upper pump rod 6 squeezes the conical plastic block 10, causing the conical plastic block 10 to expand and store energy. When the lower end of the piston 7 presses against the limit step 1002, the piston 7 stops moving downward and separates from the lower pump rod 4, opening the feed port 5. At the same time, the elastic body 8 is compressed and stored energy, and the air in the pump chamber 1 below the piston 7 is discharged along the feed port 5, the lower pump rod 4, the upper pump rod 6, and the nozzle 11. Under the action of the ventilation hole 17, the air in the pump chamber 1 above the piston 7 is connected to the outside of the pump chamber 1, thereby ensuring the smooth movement of the piston 7. When the nozzle 11 is subjected to external force, the upper pump rod 6, the lower pump rod 4, and the piston 7 are driven to move upward rapidly under the resetting action of the conical plastic block 10 and the elastic body 8. At this time, negative pressure is formed in the pump chamber below the piston 7, the one-way valve 3 is opened, and the liquid enters the pump chamber from the liquid inlet 2. When the nozzle 11 is pressed again, the one-way valve 3 is closed and the liquid in the pump chamber is compressed, thereby being sprayed out along the lower pump rod 4, the upper pump rod 6 and the nozzle 11.
