Description

Technical Field

[0001] This utility model relates to the field of daily chemical product packaging technology, and in particular to a valve needle and a perfume pump with the valve needle. Background Technology

[0002] A spray pump draws liquids or solutions under pressure, directing them into a nozzle. The atomized liquid is then sprayed out through the nozzle's fine orifices, serving various purposes such as spraying, atomizing, rinsing, and cleaning. It is widely used in personal care, healthcare, home life, and industrial and agricultural fields. Perfume pumps are a common type of spray pump. The valve needle is a crucial component of a spray pump, typically used to open and close the pump's passageway. For example... Figure 1 As shown, during the assembly and disassembly of existing spray pumps, forcibly inserting or pulling out the valve needle causes deformation and damage at point A where the valve needle and valve stem are joined, resulting in insufficient valve needle pull-out force and a short service life of the spray pump. Utility Model Content

[0003] The technical problem this invention aims to solve is to provide a valve needle and a perfume pump with the valve needle. This valve needle and the perfume pump with the valve needle can reduce or even avoid damage during the installation and disassembly of the valve needle, and extend its service life. To achieve the above-mentioned objectives, this utility model adopts the following technical solution: A valve needle, including a clearance groove.

[0004] Furthermore, the clearance groove is formed on the side of the valve needle.

[0005] Furthermore, the clearance groove is a through hole.

[0006] Another improvement is that the clearance groove is a blind hole.

[0007] Furthermore, a latch is provided on the valve needle, the latch being used to engage with the valve stem, and the clearance groove is provided at the latch.

[0008] Furthermore, the cross-section of the clearance groove is one of elliptical, circular, rectangular, rhomboid, or polygonal.

[0009] A perfume pump, including the aforementioned valve needle.

[0010] Furthermore, the perfume pump also includes a large ring for mounting the pump body onto the bottle body. The large ring can be made of an alumina bayonet, a threaded large ring, or a plastic bayonet.

[0011] This utility model discloses a valve needle and a perfume pump with the same valve needle. Because the valve needle has a relief groove, during assembly or disassembly, the valve needle is deformed by pressure at the relief groove, concentrating and eliminating the deformation caused by the force, allowing the valve needle to smoothly engage with the valve stem. After the valve needle engages with the valve stem, due to the elasticity of the plastic product, the relief groove of the valve needle returns to its original shape after deformation. With this utility model, the valve needle can smoothly engage with the valve stem, and the valve needle engagement point will not be damaged, extending the service life of both the valve needle and the perfume pump.

Detailed Implementation

[0013] The following detailed description, in conjunction with the accompanying drawings, provides a valve needle and a perfume pump incorporating the present invention. In this description, it should be understood that terms such as "left side," "right side," "upper part," "lower part," and "bottom," indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are used only for ease of description and simplification. They do not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Terms such as "first" and "second" do not indicate the importance of components and therefore should not be construed as limitations on the present invention. The specific dimensions used in this embodiment are merely illustrative and do not limit the scope of protection of the present invention.

[0014] like Figure 2 As shown, this utility model discloses a valve needle and a perfume pump with the valve needle, wherein the valve needle includes a relief groove 43. Generally, the relief groove 43 is formed on the side of the valve needle, and can be a through hole or a blind hole. Both through holes and blind holes can reduce damage to the valve needle when it deforms.

[0015] The clearance groove 43 is located on the upper part of the valve needle. Specifically, the valve needle is provided with a latch 41 for engaging with the valve stem, and the clearance groove 43 is located at the latch 41. The cross-sectional shape of the clearance groove 43 should be such that it is not easily damaged and can alleviate the deformation of the valve needle body, such as elliptical, circular, rectangular, rhomboid, or polygonal.

[0016] like Figure 3 As shown, a perfume pump includes a straw 1, a pump body 2, a glass bulb 3, a valve needle 4, a piston 5, a large ring 6, a spring 7, a gasket 8, an inner plug 9, a valve stem 10, a cap 11, a spray nozzle 12, and a push-button cap 13. A retaining ring 101 is provided inside the valve stem 10; as shown... Figure 2 As shown, a groove 42 is formed below the valve needle buckle 41; the groove 42 engages with the buckle 101 to install the valve needle 4 into the valve stem 10. During installation, because the outer diameter of the buckle 41 is larger than the inner diameter of the buckle 101, the valve needle 4 deforms. The clearance groove 43 helps to alleviate the deformation and protect the valve needle. Moreover, because the deformation is easier, the valve needle 4 is easier to engage with the valve stem 10.

[0017] In this embodiment, the large ring 6 of the perfume pump adopts the following design: Figure 4 The alumina bayonet shown. Large ring 6 can also use... Figure 5 and 6 The large threaded ring shown has internal threads, and a threaded connection is used when connecting it to the bottle body. For example... Figure 7 and 8 As shown, the large ring 6 can also use a plastic bayonet, with a bayonet protrusion 61 and a bayonet gap 62 at the bottom of the plastic bayonet.

[0018] Other components are installed as follows: The suction tube 1 is inserted into the inlet of the pump body 2, and the glass bulb is located at the bottom of the pump body 2, above the suction tube 1. The large ring 6 is installed at the top opening of the pump body 2, and the valve stem 10 extends into the pump chamber of the pump body 2 through the large ring 6. The valve needle 4 fixes the piston 5 to the bottom of the valve stem 10. An inner plug 9 is provided between the upper part of the large ring 6 and the valve stem 10, and a spring 7 is installed between the inner plug 9 and the piston 5; a gasket 8 is also provided inside the large ring 6. The spray nozzle 12 is installed on the side of the head cap 11, and the push cap is installed on the top of the head cap 11, which is inserted into the top of the valve stem 10.

[0019] Based on the description of the preferred embodiments of the present invention, it should be clear that the present invention as defined by the appended claims is not limited to the specific details set forth in the above description, and many obvious changes to the present invention without departing from the spirit or scope of the present invention may also achieve the purpose of the present invention.
