[0003] However, the above-mentioned atomizer nozzle has certain defects. For example, the invention patent with publication number CN1921949A discloses a clamping device for a jet component, in which a dead volume (liquid buffer chamber) for accommodating liquid is provided at the liquid inlet end of the jet component. When the spray is started, the liquid in the dead volume is sprayed out, the pressure is reduced, and the side of the jet component close to the dead volume is adsorbed, so that the jet component is away from the injection port. At this time, the edge of the expanded elastic molded part (elastomer) is squeezed into the gap between the jet component and the component where the injection port is located, and the edge of the elastic molded part blocks the injection port, affecting the spray effect.

[0054] In order to thoroughly understand the present application, detailed steps and detailed structures will be presented in the following description to illustrate the technical solution of the present application. The preferred embodiments of the present application are described in detail below, but in addition to these detailed descriptions, the present application may also have other implementation methods.

[0055] Example 1

[0056] This embodiment provides an atomizer nozzle, such as Figure 1-Figure 3 As shown, it comprises: a nozzle body 1, a jet component 2, an elastomer 3 and an extruded part 4.

[0057] The nozzle body 1 is the main part of the atomizer nozzle, and is used for other parts to be installed and connected based on it. The nozzle body 1 has a receiving cavity 11, and the receiving cavity 11 is used to receive other parts.

[0058] The jet component 2 is located in the accommodating chamber 11. Fig. 9 As shown, it has a liquid inlet end 21 for liquid to enter and a liquid outlet end 23 for liquid to be ejected. The characteristic of the jet component 2 is that it can convert the liquid at the liquid inlet end 21 into an atomized state and then eject it from the liquid outlet of the liquid outlet end 23. The jet component 2 is an existing product.

[0059] The elastomer 3 is filled between the inner wall 111 of the accommodating chamber 11 and the jet component 2. The elastomer 3 is a component made of a material that can be deformed by extrusion. Its specific shape is designed accordingly according to the space to be filled. The characteristic of the elastomer 3 is that one side of it will be concave after being squeezed, but the other side will expand outward or have a tendency to expand outward. If the elastomer 3 is filled in a closed space, the elastomer 3 will exert a force on the inner wall of the space when it is squeezed.

[0060] The extrusion member 4 has an injection port 421 for spraying the spray, and the injection port 421 is aligned with the liquid outlet of the jet component 2 so that the atomized liquid sprayed by the jet component 2 can pass through; the extrusion member 4 squeezes the elastic body 3 to compress the elastic body 3, and the elastic body 3 can apply an extrusion force to the jet component 2 when it is compressed, and the first component of the extrusion force is toward the injection port 421, so that the jet component 2 has a tendency to move toward the injection port 421. In this embodiment, the extrusion force is decomposed into a first component and a second component, wherein the first component of the force on the jet component 2 is toward the injection port 421, and the second component of the force on the jet component 2 is perpendicular to the first component and is from the outside of the jet component 2 to the inside. Generally, the jet component 2 and the injection port 421 are arranged along the axial direction of the atomizer nozzle. Therefore, the first component force can also be considered to be along the axial direction of the atomizer nozzle and along the direction of the jet component 2 toward the injection port 421, that is, the injection direction of the jet component 2. The second component force can also be considered to be perpendicular to the axial direction of the atomizer nozzle and from the outside of the jet component 2 toward the inside thereof.

[0061] The atomizer nozzle provided in this embodiment has an elastomer 3 filled between the inner wall 111 of the accommodating cavity 11 and the jet component 2, and the extrusion piece 4 squeezes the elastomer 3 to compress the elastomer 3. When the elastomer 3 is compressed, it can apply a thrust toward the injection port 421 of the atomizer nozzle to the jet component 2. Therefore, the jet component 2 is not easy to move away from the injection port 421, and the edge of the deformed elastomer 3 will not squeeze in between the extrusion piece 4 and the jet component 2, so the injection port 421 is not easily blocked, reducing the probability of the spray effect being affected.

[0062] The atomizer nozzle provided in this embodiment has the following working principle: when the spray is started, the pressure at the liquid inlet end 21 of the jet component 2 decreases, and the side of the jet component 2 close to the liquid inlet end 21 is adsorbed. However, since the elastomer 3 of this embodiment can apply a thrust toward the injection port 421 of the atomizer nozzle to the jet component 2 when compressed, the jet component 2 is not likely to move away from the injection port 421, and the edge of the expanded elastomer 3 will not squeeze into the gap between the jet component 2 and the extrusion member 4, and the spray effect is not easily affected.

[0063] In an optional embodiment, if Figure 2As shown, the inner diameter of the accommodating chamber 11 gradually increases along the spray direction of the jet component 2. Its working principle is: the inner wall 111 of the accommodating chamber 11 is inclined relative to the axial direction of the atomizer nozzle, and the end of the inner wall 111 close to the jet port 421 is inclined outward so that the first component of the extrusion force is directed toward the jet port 421. In this embodiment, through the inclined design of the inner wall 111, the direction of the extrusion force on the jet component 2 when the elastic body 3 is compressed is biased toward the direction close to the jet port 421, so that the first component of the extrusion force is directed toward the jet port 421. It can be understood that in addition to the above-mentioned inner wall 111 inclination method, there are other embodiments of the scheme for making the first component of the extrusion force toward the jet port 421, including but not limited to: the inner wall 111 is partially inclined, the inner wall 111 is partially protruding, and the inner wall 111 is partially concave. The setting method of the inclined inner wall 111 provided in this embodiment is simple in structure and can simply adjust the direction of the extrusion force on the jet component 2.

[0064] In an optional embodiment, if Figure 2 , Figure 3 As shown, the extrusion member 4 includes: a movable body 41 and a pressure plate 42. The movable body 41 is connected to the nozzle body 1 through a matching structure, and the movable body 41 can move relative to the nozzle body 1 by adjusting the matching structure; the pressure plate 42 is connected to the movable body 41, and the pressure plate 42 can squeeze the elastic body 3 under the drive of the movable body 41 to lock the jet component 2 and the elastic body 3 in the accommodating chamber 11. Among them, the movable body 41 is a movable part installed on the nozzle body 1, and its function is to change the degree of compression of the elastic body 3 by the pressure plate 42. Among them, the matching structure is a connection structure between the movable body 41 and the nozzle body 1, so as to realize that the movable body 41 can move relative to the nozzle body 1. For example, the matching structure can be an external thread provided on the nozzle body 1 and an internal thread provided on the movable body 41; or, it can be a card slot provided on the nozzle body 1 and a buckle provided on the movable body 41.

[0065] In an optional embodiment, if Figure 2 As shown, the pressing plate 42 includes: a pressing plate body and a convex block 43 protruding from the pressing plate body, the pressing plate body abuts against the end face 10 of the nozzle body 1, and the convex block 43 is located in the accommodating cavity 11. The setting of the convex block 43 can facilitate the extrusion member 4 to extrude the elastic body 3, the extrusion position is more concentrated, and it is easier to control the stretching direction of the elastic body 3 when it is deformed, that is, it is easy to control the extrusion force direction of the jet component 2. It can be understood that in other embodiments, when the extrusion member 4 is an integral structure, the extrusion body of the extrusion member 4 serves as the above-mentioned pressing plate body.

[0066] In an optional embodiment, if Figure 2As shown, the protrusion 43 is located on the side of the accommodating chamber 11 away from the jet component 2, and the protrusion 43 can squeeze the side of the elastomer 3 away from the jet component 2 to increase the second component of the squeezing force, and the second component is perpendicular to the first component along the outer side of the jet component 2 toward the inner side. In this embodiment, the position of the protrusion 43 is designed to be on the side away from the jet component 2, so that the squeezed elastomer 3 is more likely to have a tendency to expand toward the jet component 2, and the clamping force of the jet component 2 is greater, which is conducive to better stabilizing the jet component 2. In other embodiments, the position of the protrusion 43 may not be limited to being located on the side of the accommodating chamber 11 away from the jet component 2, and the position of the protrusion 43 may be spaced from the outer side wall 22 of the jet component 2, so that the squeezed elastomer 3 is more likely to have a tendency to expand toward the jet component 2.

[0067] In an optional embodiment, if Figure 2 As shown, the atomizer nozzle also includes a gasket 6, which is located between the jet component 2 and the extrusion component 4. The gasket 6 has a through hole aligned with the injection port 421, and the through hole is provided to avoid shielding the injection port 421. The function of the gasket 6 is to prevent the end of the jet component 2 from colliding and rubbing with the extrusion component 4 during long-term use and causing wear. Generally, the jet component 2 of the atomizer nozzle is made of silicon dioxide, and the part where the injection port 421 is located is made of metal. When the jet component 2 is in direct contact with the part where the injection port 421 is located, collision and friction during long-term use may cause the jet component 2 to break; the gasket 6 of this embodiment can protect the end of the jet component 2 to prevent it from breaking.

[0068] In an optional embodiment, the gasket 6 can be composed of a single layer of plastic material or a multi-layer plastic material, preferably PEEK (polyetheretherketone). One side of the gasket 6 can be coated with glue, and the gasket 6 can be fixed to one side of the extrusion 4 by bonding, welding, etc., so as to achieve the fixation of the gasket 6 and prevent the gasket 6 from moving during the assembly process, resulting in a decrease in assembly accuracy. It is understandable that the gasket 6 can also be provided with a glue layer on both sides, so that the extrusion 4, the gasket 6 and the jet component 2 can be combined into a tight whole.

[0069] In an optional embodiment, if Figure 2As shown, when the elastic body 3 is not squeezed, a vacant area is formed between the elastic body 3 and the extrusion piece 4, and the elastic body 3 stretches into the vacant area after being squeezed. In this embodiment, by setting the vacant area, a stretching space can be provided to a part of the compressed elastic body 3, so as to prevent the elastic body 3 from being squeezed into the gap of other parts due to too small stretching space. The vacant area is enclosed by the elastic body 3 and the extrusion piece 4, or the vacant area is enclosed by the elastic body 3, the extrusion piece 4, and one of the jet component 2 and the inner wall 111, or the vacant area is enclosed by the elastic body 3, the extrusion piece 4, the jet component 2 and the inner wall 111.

[0070] In an optional embodiment, if Figure 2 As shown, the inner edge of the elastic body 3 has a chamfered structure 31, and the chamfered structure 31 and the extrusion piece 4 and the jet component 2 form the vacant area. In this embodiment, the chamfered structure 31 can be used as a guide angle on the one hand, so that the jet component 2 can be inserted and installed from the end of the elastic body 3 with the chamfered structure 31. On the other hand, the gap formed between the chamfered structure 31 and the extrusion piece 4 and the jet component 2 is used as the vacant area for the elastic body 3 to stretch when it is compressed. Its processing method is simple and the effect is good. Among them, the chamfered structure 31 can be a rounded corner (R angle) or a bevel angle (C angle).

[0071] In an optional embodiment, if Figure 2 As shown, the nozzle body 1 also has a liquid buffer chamber 12, which is located at the liquid inlet end 21 of the jet component 2 and is connected to the liquid inlet port 211 of the jet component 2 for liquid storage; the vacant area is located outside the liquid outlet end 23 of the jet component 2. In this embodiment, the position of the vacant area is staggered from the position of the liquid buffer chamber 12 to avoid the elastic body 3 from affecting the liquid buffer chamber 12 when it stretches. It can be understood that in other embodiments, the vacant area is not adjacent to the liquid buffer chamber 12 and is not likely to affect it.

[0072] In an optional embodiment, the compression amount of the elastic body 3 along the axial height of the atomizer nozzle after assembly is 5% to 60%, preferably 10% to 40%, more preferably 20% to 40%, and the volume compression ratio of the elastic body 3 after assembly is 3% to 70%, preferably 10% to 50%, more preferably 15% to 40%. The hardness of the elastic body 3 is 30 to 80 Shore A, preferably 50 to 75 Shore A.

[0073] In an optional embodiment, if Fig. 9 As shown, the jet component 2 can be installed in the elastomer 3, and the inner peripheral wall 32 of the elastomer 3 squeezes the outer peripheral wall 22 of the jet component 2 from the outside to the inside, thereby providing the squeezing force so that the liquid outlet end 23 of the jet component 2 fits the extrusion piece 4.

[0074] This embodiment also provides a sprayer, including the above-mentioned atomizer nozzle, which reduces the probability of the spray effect being affected.

[0075] Example 2

[0076] This embodiment provides an atomizer nozzle, such as Figure 4 As shown, the difference from Example 1 is that:

[0077] When the extrusion piece 4 is not installed, the height of the elastic body 3 along the axial direction of the atomizer nozzle is greater than the depth of the accommodating cavity 11;

[0078] When the extrusion member 4 is completely installed, the extrusion member 4 presses the elastic body 3 .

[0079] In an optional embodiment, if Figure 4 As shown, one side of the extrusion piece 4 used to extrude the elastic body 3 is a plane, and when the extrusion piece 4 is installed, the plane abuts against the end face 10 of the nozzle body 1. In this embodiment, the pressing plate 42 is designed with one side being a plane, and the structure is simple and easy to manufacture. The elastic body 3 is designed to have a height greater than or equal to the depth of the accommodating cavity 11, so that the pressing plate 42 can extrude it.

[0080] In an optional embodiment, if Figure 4 As shown, in this embodiment, the extrusion member 4 is an integral structure, and the pressure plate 42 is integrally connected with the movable body 41. The solution of this embodiment can simplify the structure of the extrusion member 4, reduce the manufacturing difficulty, and reduce the mold cost. It can be understood that in other embodiments, the pressure plate 42 and the movable body 41 can be a split structure, independent of each other, to improve the flexibility of part matching.

[0081] Example 3

[0082] This embodiment provides an atomizer nozzle, such as Figure 5 As shown, the difference from Example 1 is that the height of the elastic body 3 along the axial direction of the atomizer nozzle is h1, the depth of the accommodating cavity 11 along the axial direction of the atomizer nozzle is h2, and the height of the protrusion 43 along the axial direction of the atomizer nozzle is h3; h1<h2,h1+h3> h2, when the pressing plate body abuts against the end face 10 of the nozzle body 1, the protrusion 43 squeezes the elastic body 3. Under this size design, on the one hand, the structure that the elastic body 3 does not completely fill the accommodating cavity 11 is adopted, so that the elastic body 3 has enough expansion space after deformation, and is therefore less likely to be squeezed into between the extrusion piece 4 and the jet component 2; on the other hand, in order to compensate for the inconvenience of squeezing the elastic body 3 under this design, the provided protrusion 43 can facilitate squeezing the elastic body to compress it.

[0083] In an optional embodiment, if Figure 5As shown, the nozzle body 1 includes a mounting body 14 and a support body 13, the mounting body 14 is connected to the extrusion member 4 through a matching structure, the support body 13 is connected to the mounting body 14, and the accommodating cavity 11 is formed in the support body 13. In this embodiment, the nozzle body 1 adopts a split design, and the support body 13 has strong flexibility in assembly and disassembly.

[0084] In an optional embodiment, the nozzle body 1 further includes a filter element 16 , which is connected to the liquid inlet end 21 of the jet component 2 and is located between the mounting body 14 and the support body 13 .

[0085] like Figure 5 As shown, the liquid inlet end 21 of the jet component 2 needs to be installed with a filter element 16. In order to facilitate the installation of the filter element 16, the installation position of the filter element 16 can be designed at the junction of the support body 13 and the installation body 14. Under this structure, the detachable structure of the support body 13 can facilitate the installation of the filter element 16. Figure 5 As shown, in order to ensure the sealing performance between the support body 13 and the installation body 14, a sealing ring 15 may be provided between the two.

[0086] Example 4

[0087] This embodiment provides an atomizer nozzle, such as Figure 6 As shown, the difference from Example 1 is that the atomizer nozzle further includes an internal pressure block 5, which is located on the inner wall 111 and can squeeze the elastic body 3 to increase the squeezing force. The arrangement of the internal pressure block 5 can facilitate squeezing the elastic body 3, the squeezing position is more concentrated, and it is easier to control the stretching direction of the elastic body 3 when it is deformed, that is, it is easy to control the squeezing force direction of the jet component 2.

[0088] In an optional embodiment, if Figure 6 As shown, the internal pressure block 5 is fixed to the inner wall 111 of the accommodating chamber 11 on the side away from the jet component 2. The internal pressure block 5 can squeeze the side of the elastic body 3 away from the jet component 2 to increase the second component of the squeezing force, which is directed from the outside of the jet component 2 toward the inside. The internal pressure block 5 is designed to be located on the side away from the jet component 2, so that the squeezed elastic body 3 is more likely to expand toward the jet component 2, and the clamping force on the jet component 2 is greater, which is conducive to better stabilizing the jet component 2.

[0089] like Figure 6 As shown, in this embodiment, the extrusion piece 4 does not have the protrusion 43 , but in other embodiments, the protrusion 43 and the inner pressure block 5 may be provided at the same time.
