Description

Technical Field

[0001] This invention relates to the field of perfume pump technology, specifically to an all-plastic perfume pump and its bottle. Background Technology

[0002] Perfume is a product made by dissolving fragrances in ethanol, sometimes with the addition of trace amounts of pigments, antioxidants, bactericides, glycerin, surfactants, and other additives as needed. It has a rich and fragrant aroma and is primarily used by spraying it onto clothing, handkerchiefs, and hair to emit a pleasant scent; it is an important cosmetic product.

[0003] When using perfume, it is usually stored in a perfume bottle and sprayed out by squeezing the cap of the perfume pump. Currently, the spring in the perfume pump is made of metal. During recycling, the metal spring is separated from the pump body first and then recycled separately, resulting in high recycling costs. Some perfume pumps use plastic springs, but due to the influence of the material itself, the rebound force is insufficient, and even leakage may occur. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an all-plastic perfume pump, including a pump body, in which plastic beads are disposed, the pump body is installed in a large ring, a piston is disposed inside the pump body, a valve needle is inserted into the piston, a valve stem is connected to the upper end of the valve needle, a connecting cover is snapped into the top opening of the pump body, a spring is disposed at the upper end of the connecting cover, the spring is sleeved on the valve stem, and the valve stem and the valve needle are used to support and limit the spring.

[0005] Preferably, both the spring and the plastic bead are made of plastic.

[0006] Preferably, the bottom of the pump body is provided with a receiving cavity for placing plastic beads, and the inner wall of the pump cavity of the pump body is provided with an inner groove for locking the connecting cover.

[0007] Preferably, the valve needle is integrally formed, and includes a needle body and a sealing ring. The upper end face of the sealing ring is conical. The valve needle is inserted into the piston, and then the piston is installed in the pump body. The bottom of the piston and the pump body form a cavity structure.

[0008] Preferably, the connecting cover has an inner sleeve in the middle, which is used to fit around the valve stem. The outer wall of the middle part of the connecting cover has a first outer flange, which is used to connect the large ring. The upper end of the connecting cover has an upper support groove, which is used to support the spring piece. The lower end of the connecting cover has a lower support groove, which is used to fit around the opening of the pump body.

[0009] Preferably, the valve stem includes a stem body and a boss, the diameter of the boss being larger than the diameter of the stem body. The inner wall of the stem body is provided with an inner convex rib. The valve needle is inserted into the stem body, and the inner convex rib is embedded in the annular groove to fix the valve needle to the valve stem.

[0010] Preferably, the spring sheet has a hollow columnar structure, with an upper support portion at the upper end for insertion into a limiting groove, and a lower support portion at the lower end for insertion into the upper support groove.

[0011] Preferably, the spring sheet has a protrusion in the middle, the protrusion is an arc surface, and a first inclined surface is provided at the connection between the protrusion and the upper support. The first inclined surface is a conical surface, and the diameter of the spring sheet gradually decreases as it extends axially from the protrusion to the upper support.

[0012] Preferably, a second inclined surface is provided at the connection between the protrusion and the lower support. The second inclined surface is an inverted conical surface, and the diameter of the spring sheet gradually decreases as it extends axially from the protrusion to the lower support.

[0013] The present invention provides a bottle body with an external thread at the opening and a large ring connected to the bottle body for storing contents.

[0014] The technical effects and advantages of this invention are as follows:

[0015] 1. In this invention, the spring and plastic bead are made of plastic. The plastic spring replaces the metal spring, which facilitates the overall recycling of the perfume pump, meets environmental protection requirements, and reduces recycling costs.

[0016] 2. In this invention, the perfume pump can be used on different bottle bodies. When the contents are used up, the large ring can be unscrewed to replenish the contents and reuse them again.

[0017] 3. In this invention, the diameter of the spring piece at the protrusion is larger than the diameter of the first inclined surface and the second inclined surface. The protrusion has relatively greater flexibility, while the first and second inclined surfaces have greater hardness than the protrusion. The protrusion facilitates the compression of the spring piece, and the first and second inclined surfaces facilitate the reset of the spring piece from the compressed state, thus providing greater elasticity, better sealing, and preventing leakage.

[0018] 4. In this invention, the plastic beads are lighter than glass beads of the same volume, which allows the plastic beads to separate from the bottom interface of the pump body under a smaller internal pressure, making it convenient to feed. Attached Figure Description

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0037] Please see Figure 1-3 This embodiment provides an all-plastic perfume pump, including a pump body 1, with plastic beads 2 inside the pump body 1. The pump body 1 is installed inside a large ring 10, and a gasket 11 is provided inside the large ring 10. The gasket 11 is sleeved on the outside of the pump body 1. A suction tube 12 is connected to the bottom interface of the pump body 1. A piston 4 is provided inside the pump body 1, and a valve needle 3 is inserted into the piston 4. The upper end of the valve needle 3 is connected to a valve stem 6. A connecting cover 5 is snapped into the top opening of the pump body 1. A spring piece 7 is provided on the upper end of the connecting cover 5. The spring piece 7 is sleeved on the valve stem 6. The valve stem 6 is connected to the valve needle 3 to limit the spring piece 7. The valve stem 6 is connected to a button cap 9. A spray plate 8 is provided at the liquid outlet of the button cap 9. The spring piece 7 is limited by the valve stem 6 and the valve needle 3. The spring piece 7 and the plastic beads 2 are both made of plastic, which can be continuously recycled and is easy to recycle, meeting environmental protection requirements. This perfume pump can be used for different bottle bodies. When the contents are used up, the contents can be replenished by unscrewing the large ring 10, and it can be recycled again.

[0038] In this embodiment, refer to Figure 4As shown, the bottom of the pump body 1 is provided with a receiving cavity 101 for placing plastic beads 2. The inner wall of the receiving cavity 101 is provided with oblique protruding ribs to limit the plastic beads 2 and prevent the plastic beads 2 from falling out of the receiving cavity 101. The inner wall of the pump cavity of the pump body 1 is provided with an inner groove 102, which is used to clamp the connecting cover 5. The connecting cover 5 plays a sealing role for the pump body 1.

[0039] In this embodiment, refer to Figure 5-6 As shown, the valve needle 3 includes a needle body 301 and a sealing ring 305. The upper end face of the sealing ring 305 is conical. The valve needle 3 is integrally formed. The needle body 301 has an outlet hole 303 inside and an inlet 302 at the bottom, so that liquid can enter from the inlet 302 and flow out from the outlet hole 303. The upper outer wall of the needle body 301 is provided with an annular groove 304 for fixing the needle body 301 to the valve stem 6. The valve needle 3 is inserted into the piston 4, and then the piston 4 is installed in the pump body 1. The piston 4 and the bottom of the pump body 1 form a cavity structure, which is used to accommodate the contents.

[0040] In this embodiment, refer to Figure 7-8 As shown, the piston 4 has an insertion hole 401 in the middle, which is used to insert the valve needle 3. The piston 4 has a sealing cone surface 402 on the inner wall at the bottom of the insertion hole 401. When discharging, the sealing cone surface 402 separates from the upper end face of the sealing ring 305 and the material enters the valve needle 3. When discharging, the sealing cone surface 402 fits against the upper end face of the sealing ring 305 and can play a sealing role.

[0041] See Figure 9-10 As shown, the connecting cover 5 has an inner sleeve 501 in the middle, which is used to fit around the valve stem 6. The outer wall of the middle part of the connecting cover 5 has a first outer flange 502, which is used to connect the large ring 10. The upper end of the connecting cover 5 has an upper support groove 503, which is used to support the spring piece 7. The lower end of the connecting cover 5 has a lower support groove 504, which is used to fit around the opening of the pump body 1. The lower end of the connecting cover 5 has a second outer flange 505, which is inserted into the pump body 1 and cooperates with the inner groove 102 to snap the connecting cover 5 onto the pump body 1. The bottom of the connecting cover 5 is used to limit the piston 4.

[0042] See Figure 11-12As shown, the valve stem 6 includes a stem body 601 and a boss 602. The diameter of the boss 602 is larger than the diameter of the stem body 601. After the valve stem 6 is connected to the push cap 9, the upper end face of the boss 602 contacts the push cap 9. The lower end face of the boss 602 is provided with a limiting groove 603. The limiting groove 603 is annular and is used to limit the upper end of the spring piece 7. The upper inner wall of the stem body 601 is provided with a fixing groove 604. After the stem body 601 is connected to the push cap 9, the valve stem 6 is fixed to the push cap 9 by cooperating with the push cap 9 through the fixing groove 604. The inner wall of the stem body 601 is provided with an inner convex rib 605. The valve needle 3 is inserted into the stem body 601, and the inner convex rib 605 is embedded in the annular groove 304 to fix the valve needle 3 to the valve stem 6.

[0043] See Figure 13-14 As shown, the spring piece 7 has a hollow columnar structure. An upper support portion 702 is provided at the upper end of the spring piece 7, which is used to insert into the limiting groove 603. A lower support portion 703 is provided at the lower end of the spring piece 7, which is used to insert into the upper support groove 503. The connecting cover 5 and the valve stem 6 limit the movement of the spring piece 7. When the pressing cap 9 drives the valve stem 6 to move upward, the limiting groove 603 and the upper support groove 503 support and limit the upper support portion 702 and the lower support portion 703 of the spring piece 7. This prevents the spring piece from being pushed upward. The misalignment of the upper and lower ends of the spring 7 causes it to lose its supporting elasticity. On the other hand, the air inside the hollow cylindrical spring 7 is not easy to flow out, and the air pressure increases. When used with the spring 7, it has greater elasticity. When pressed, it is conducive to the ejection of the contents. When the button 9 is released, the spring 7 itself and the air pressure are used to facilitate the reset of the spring 7, which in turn facilitates the reset of the button 9 and the entry of the contents into the piston 4 and the bottom of the pump body 1 to form a cavity structure with greater elasticity and better sealing, so as not to produce leakage.

[0044] Furthermore, a protrusion 701 is provided in the middle of the spring piece 7. The protrusion 701 is an arc surface. A first inclined surface 704 is provided at the connection between the protrusion 701 and the upper support 702. The first inclined surface 704 is a conical surface. The diameter of the spring piece 7 gradually decreases as it extends axially from the protrusion 701 to the upper support 702. A second inclined surface 705 is provided at the connection between the protrusion 701 and the lower support 703. The second inclined surface 705 is an inverted conical surface. The diameter of the spring piece 7 gradually decreases as it extends axially from the protrusion 701 to the lower support 703. When the button cap 9 is pressed down, the valve stem 6 moves downward, squeezing the upper support 702. The first inclined surface 704 squeezes the protrusion 701 downward. The portion 701 expands outward, thereby compressing the spring 7. Because the diameter of the spring 7 at the protrusion 701 is larger than the diameter at the first inclined surface 704 and the second inclined surface 705, the flexibility at the protrusion 701 is relatively greater. The first inclined surface 704 and the second inclined surface 705 are relatively harder than the protrusion 701. The protrusion 701 facilitates the compression of the spring 7, and the first inclined surface 704 and the second inclined surface 705 facilitate the reset of the spring 7 from the compressed state. When the button 9 is released, the spring 7 resets, pushing the valve stem 6 upward and resetting. By using a plastic spring 7 instead of a metal spring, the perfume pump can be recycled and reused, and the requirements of environmental protection and energy saving can be met.

[0045] See Figure 15-16 As shown, a sleeve 1001 is provided inside the large ring 10, and a support ring 1002 is provided inside the sleeve 1001. The support ring 1002 is used to support the connecting cap 5. A groove 1005 is provided on the inner wall of the sleeve 1001. The connecting cap 5 is inserted into the sleeve 1001, and the first outer flange 502 is embedded in the groove 1005, connecting the connecting cap 5 to the large ring 10. An annular groove 1003 is provided between the sleeve 1001 and the inner wall of the large ring 10. The annular groove 1003 is used to limit the horizontal movement of the button cap 9 and reduce the shaking caused when the button cap 9 is pressed. An internal thread is provided at the lower opening of the sleeve 1001 for connecting the bottle body.

[0046] In another embodiment, a bottle body is provided, the opening of which is provided with external threads, the bottle body is connected to an all-plastic perfume pump and its bottle body, and is used to store perfume.

[0047] The working principle of this invention is:

[0048] When using this perfume pump, connect the large ring 10 to the bottle body. The gasket 11 is located at the opening of the bottle body to seal it. Press down on the cap 9 to drive the valve stem 6 to move downward, which in turn drives the valve needle 3 and piston 4 to move downward. The valve stem 6 and the connecting cover 5 squeeze the spring 7, which squeezes the contents of the cavity structure formed by the piston 4 and the bottom of the pump body 1. At this time, the plastic bead 2 is subjected to downward pressure, which blocks the bottom of the pump body 1. The cavity structure increases, and the contents push the piston 4 upward. The valve needle 3 continues to move downward under external pressure. The space of the cavity structure gradually decreases, so that the sealing cone surface 402 separates from the sealing ring 305 and exposes the liquid inlet 302. The contents of the cavity structure enter the liquid outlet 303 from the liquid inlet 302, and then are sprayed out in a mist from the spray plate 8 through the valve stem 6 and the cap 9. After the bottom surface of the cap 9 contacts the bottom surface of the annular groove 1003, the cap 9 stops moving upward, completing one spraying cycle.

[0049] When the cap 9 is released, the spring 7 extends, pushing the valve stem 6 upward and causing the valve needle 3 to move upward. The space of the cavity structure gradually increases, and a negative pressure is generated inside the cavity structure. Under the action of atmospheric pressure, the contents inside the bottle enter the cavity structure along the suction tube 12 and pushes open the plastic bead 2. Because the plastic bead 2 is lighter than the glass bead for the same volume, the plastic bead 2 can separate from the bottom interface of the pump body 1 under a small pressure of the contents, thus realizing feeding. When the pressure inside the cavity structure and the pressure inside the bottle are balanced, the sealing ring 305 of the valve needle 3 is attached to the sealing cone surface 402 of the piston 4, and the contents will not flow back into the bottle. At this time, the cavity structure is used to temporarily store the contents for the next spray.
