[0027] This application is based on the findings and understanding of the following facts and issues:

[0028] In the color sorter of related technologies, the spray valve is driven by an electromagnetic drive to move the valve plate to open and close the air passage. During the repeated movement of the valve plate, it will collide and rub against the drive. After long-term use, the drive and the valve plate will wear down, affecting the accuracy of the valve plate's movement and sealing, resulting in a reduction in the service life of the spray valve.

[0029] In the color sorter spray valve of the related technology, a pad is set in the valve body to restrict the movement of the valve plate when the valve plate is opened, thereby reducing the movement range of the valve plate and thus reducing the wear rate of the valve plate. However, wear will also occur between the valve plate and the pad. As the usage time increases, the limiting effect of the pad gradually decreases, causing the valve plate to still collide and rub against the driving component, resulting in wear between the valve plate and the driving component and affecting the service life of the spray valve.

[0033] The spray valve 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0034] like Figures 1-6 As shown, the spray valve 1 according to an embodiment of the present invention includes a valve body 10, a valve plate 20, a drive member 30, and an elastic body 40.

[0035] The valve body 10 has an air passage 11. A valve plate 20 is movably disposed within the valve body 10 between an open position (open air passage 11) and a closed position (closed air passage 11). A drive member 30 is disposed within the valve body 10 and located above the valve plate 20 (the vertical direction is shown by the arrow in the figure and is for illustrative purposes only, not a limitation on the actual installation direction). The drive member 30 is adapted to drive the valve plate 20 from the closed position to the open position. An elastic body 40 is disposed on the end face of the drive member 30 facing the valve plate 20; in other words, the elastic body 40 is disposed on the lower end face of the drive member 30, and the valve plate 20 abuts against the elastic body 40 in the open position.

[0036] Specifically, Figure 1 The valve plate 20 is in the closed position. Figure 2 The middle valve plate 20 is located between the open position and the closed position.

[0037] Air passage 11 is located below valve plate 20.

[0038] The driving component 30 can be an electromagnetic driving component, and the valve plate 20 is a ferromagnetic material component. When the driving component 30 is energized, it generates a magnetic force to attract the valve plate 20, causing the valve plate 20 to move from the closed position to the open position.

[0039] In the related technology, when the valve plate reaches the open position, it collides and rubs with the driving component, causing wear on the driving component and the valve plate, affecting the movement and sealing effect of the valve plate, and affecting the service life of the spray valve.

[0040] According to the present invention, the spray valve 1 has an elastic body 40 provided on the end face of the driving member 30 facing the valve plate 20. When the valve plate 20 moves from the closed position to the open position, it comes into contact with the elastic body 40. The elastic body 40 is compressed and buffers the movement of the valve plate 20. Compared with the spray valve in the related art, this not only avoids the valve plate 20 from directly contacting the driving member 30 and avoiding wear of the driving member 30, but also, because the elastic body 40 is elastic, the wear between the valve plate 20 and the elastic body 40 can be reduced by the buffering effect of the elastic body 40 on the valve plate 20. This reduces the wear rate of the valve plate 20, the driving member 30 and the elastic body 40, and extends the service life of the spray valve 1.

[0041] Therefore, the spray valve 1 according to the present invention has advantages such as being less prone to wear and having a long service life.

[0042] The spray valve 1 according to a specific embodiment of the present invention is described below with reference to the accompanying drawings.

[0043] In some specific embodiments of this utility model, such as Figures 1-6 As shown, the spray valve 1 according to an embodiment of the present invention includes a valve body 10, a valve plate 20, a drive member 30, and an elastic body 40.

[0044] Specifically, such as Figures 1-3 As shown, the end face of the drive member 30 is provided with a positioning groove, and the elastic body 40 fits in the positioning groove and protrudes from the end face of the drive member 30. In other words, the lower end face of the drive member 30 is provided with a positioning groove, and the elastic body 40 fits in the positioning groove and protrudes downward from the lower end face of the drive member 30. This facilitates the installation of the elastic body 40, facilitates the positioning of the elastic body 40, prevents the elastic body 40 from shifting, and guides the compression direction of the elastic body 40, reducing the relative displacement between the elastic body 40 and the valve plate 20 in the length direction of the valve plate 20, thereby reducing the wear between the elastic body 40 and the valve plate 20.

[0045] Advantageously, such as Figure 1 and Figure 2As shown, the end face of the elastomer 40 facing the valve plate 20 is an arc-shaped surface that bulges outward from the center to the edge. In other words, the lower end face of the elastomer 40 is an arc-shaped surface that bulges downward from the center to the edge. This reduces the contact area between the elastomer 40 and the valve plate 20, further reducing wear between them.

[0046] Optionally, such as Figures 1-6 As shown, the elastic body 40 is located at the center of the lower end face of the drive member 30. This allows the elastic body 40 to be subjected to more uniform force, avoids relative displacement between the elastic body 40 and the valve plate 20 in the length direction of the valve plate 20, and thus reduces wear on the elastic body 40 and the valve plate 20.

[0047] In some embodiments, the elastomer 40 is a single piece. In other words, the elastomer 40 is entirely made of elastic material. This allows for elastic deformation of the elastomer 40 and reduces the number of parts.

[0048] In other embodiments, the elastomer 40 includes an elastic element and a positioning element. The elastic element is housed within the positioning groove and is adapted to undergo elastic deformation. The positioning element is connected to the elastic element and is adapted to move axially within the positioning groove, protruding from the positioning groove. Specifically, the positioning element can be either a rigid or flexible element. This allows the overall elastic deformation of the elastomer 40 to be achieved through the elastic deformation of the elastic element.

[0049] Figures 1-6 The spray valve 1 according to some examples of the present invention is shown. For example... Figures 1-3 As shown, the spray valve 1 also includes a pad 50, which is disposed inside the valve body 10 and on the same side as the drive member 30 in the thickness direction of the valve plate 20. In other words, the pad 50 is located above the valve plate 20, and the valve plate 20 abuts against the pad 50 when it is in the open position. This not only allows the pad 50 to limit the movement range of the valve plate 20, but also allows the pad 50 to share the force when the valve plate 20 moves to the open position, thereby reducing the wear of the valve plate 20.

[0050] Specifically, such as Figure 1 and Figure 2 As shown, when the valve plate 20 is in the open position, the pad 50 abuts against the end of the valve plate 20, and the elastic body 40 abuts against the middle of the valve plate 20. This allows the force on the valve plate 20 when it moves to the open position to be distributed along the length of the valve plate 20, thereby reducing wear at each contact point.

[0051] Advantageously, such as Figure 1As shown, when the valve plate 20 is in the closed position, the distance between the valve plate 20 and the elastic body 40 is less than the distance between the valve plate 20 and the pad 50. Specifically, during the process of the valve plate 20 moving from the closed position to the open position, it first contacts the elastic body 40, which cushions the valve plate 20. Then, as the valve plate 20 continues to move towards the open position, the elastic body 40 is further compressed until the valve plate 20 abuts against the pad 50. This allows the valve plate 20 to contact the elastic body 40 before contacting the pad 50, and after being cushioned by the elastic body 40, it abuts against the pad 50, thereby reducing wear between the valve plate 20 and the pad 50.

[0052] More specifically, such as Figures 1-5 As shown, the spray valve 1 also includes a spring-loaded member 60, which is disposed within the valve body 10 and adapted to drive the valve plate 20 from the open position to the closed position. Specifically, when the valve plate 20 needs to be opened, the drive member 30 is energized to drive the valve plate 20 to overcome the spring force of the spring-loaded member 60 and move from the closed position to the open position. When the valve plate 20 needs to be closed, the drive member 30 is de-energized so that the valve plate 20 moves from the open position to the closed position under the spring force of the spring-loaded member 60. In this way, the spring-loaded member 60 can be used to drive the valve plate 20 from the open position to the closed position, facilitating the valve plate 20 to spring back and reset.

[0053] Furthermore, such as Figure 1 and Figure 2 As shown, the valve body 10 has a fulcrum portion 12. The fulcrum portion 12 and the driving member 30 are located on the same side of the valve plate 20 in the thickness direction. The valve plate 20 abuts against the fulcrum portion 12 and is positioned between the spring member 60 and the fulcrum portion 12. The contact position between the spring member 60 and the valve plate 20 is on the side away from the driving member 30 from the contact position between the fulcrum portion 12 and the valve plate 20. When the valve plate 20 is in the open position, the spring member 60 is compressed and can pop out to drive the valve plate 20 to switch to the closed position. In other words, the fulcrum portion 12 is located above the valve plate 20, and the spring member 60 is located below the valve plate 20 and abuts against the lower surface of the valve plate 20. In this way, the fulcrum portion 12 can be used as a fulcrum to make the valve plate 20 form a lever movement. The spring member 60 acts on one side of the fulcrum portion 12 on the valve plate 20, causing the other side of the fulcrum portion 12 on the valve plate 20 to move, thereby realizing the opening and closing of the valve plate 20.

[0054] Specifically, such as Figures 3-6 As shown, the air passage 11, valve plate 20, drive member 30, and elastic body 40 are multiple and are spaced apart along the circumference of the valve body 10, and the rebound member 60 is annular and extends along the circumference of the valve body 10.
