[0033] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0034] Next, the gas valve and the color sorter according to the embodiments of the present application are described.

[0035] refer to Figures 1-6 It is understood that the gas valve implemented according to the present application includes a valve body 100 , a baffle 200 and a gasket 300 .

[0036] The valve body 100 defines a chamber 110 and an air passage 120 that are selectively connected, so that the functions of air injection or air inhalation are achieved by opening and closing the chamber 110 and the air passage 120. The baffle 200 is connected to the valve body 100 and is adapted to switch between a first position and a second position to open or close the air passage 120 to connect to one end of the chamber 110. When the baffle 200 is switched to the first position, the baffle 200 opens the air passage 120 to connect the air passage 120 with the chamber 110. When the baffle 200 is switched to the second position, the baffle 200 closes the air passage 120 to isolate the air passage 120 from the chamber 110. The gasket 300 is connected to the valve body 100 and is adapted to push against the baffle 200 at its end when the baffle 200 is in the first position.

[0037] The first position and the second position of the baffle 200 can be combined Figure 1-2 The exemplary situation shown is understood.

[0038] In this example, the baffle 200 and the spacer 300 are both disposed in the chamber 110 and the baffle 200 moves in the chamber 110 , wherein: Figure 1 The baffle 200 is in the first position. Figure 2 The baffle 200 is in the second position, and the baffle 200 switches from the second position to the first position to open the airway 120. For ease of description, the direction of movement of the baffle 200 from the second position to the first position is defined as the opening direction, and the end of the airway 120 connected to the chamber 110 is defined as the first opening.

[0039] Specifically, refer to Figure 1 In the illustrated embodiment, the baffle 200 is in the first position, where the side of the baffle 200 facing the air passage 120 is separated from the first opening to enable the air passage 120 to communicate with the chamber 110. Figure 2 In the illustrated situation, the baffle 200 is in the second position. At this time, the baffle 200 is pushed toward the first opening on the side of the airway 120 to form a seal for the first opening, thereby isolating the airway 120 from the chamber 110 .

[0040] In combination with the description of the first position and the second position, the pushing effect of the pad 300 on the baffle 200 is further explained. The pad 300 can be set in the opening direction of the baffle 200. The baffle 200 switches to the first position to form an opening and pushes against the pad 300. Therefore, the baffle 200 moves toward the pad 300 located in its opening direction and stops after being pushed by the pad 300. The pad 300 forms a limit for the baffle 200.

[0041] For a better explanation, we can continue to combine Figure 1-2 The example continues to understand.

[0042] When the baffle 200 is Figure 2 The second position shown switches to Figure 1 After reaching the first position shown, the pad 300 pushes against the right end of the baffle 200, thereby pushing against the baffle 200 and limiting the opening direction of the baffle 200. After the pad 300 pushes against the end of the baffle 200, the pad 300 is limited, preventing the baffle 200 from moving further in the opening direction, thereby limiting the range of movement of the baffle 200 when opening.

[0043] Therefore, the pad 300 is suitable for avoiding or reducing the situation where the baffle 200 is damaged due to the baffle 200 colliding with other components in the chamber 110 due to the excessive movement of the baffle 200; of course, the pad 300 is also suitable for avoiding or reducing the situation where the baffle 200 is fatigue damaged due to repeated large-scale movement of the baffle 200 itself.

[0044] According to the air valve of the embodiment of the present application, it includes a baffle 200 that switches between a first position and a second position, and when the baffle 200 switches to the first position, it is pushed by the pad 300. The pad 300 pushes the baffle 200 to provide a limiting effect for the baffle 200 to prevent the baffle 200 from over-opening and damaging the baffle 200, thereby improving the working conditions of the baffle 200 and extending the service life of the baffle 200 and even the air valve.

[0045] According to a further embodiment of the present application, the air valve also includes a driving member 400, which is arranged in the valve body 100. The driving member 400 at least drives the baffle 200 to switch from the second position to the first position, and the driving member 400 and the gasket 300 are located on the same side of the baffle 200, and the gasket 300 pushes and limits the movement of the baffle 200 toward the driving member 400.

[0046] In some cases, the driver 400 is adapted to drive the baffle 200 from the second position to the first position. For example, the driver 400 is configured as an electromagnet and the baffle 200 is configured as a magnetic metal. When the electromagnet is energized, the baffle 200 is attracted to switch from the second position to the first position. In other cases, the driver 400 is adapted to switch the baffle 200 from the second position to the first position and can also switch the baffle 200 from the first position to the second position. For example, the driver 400 is configured as an electromagnet and the baffle 200 is configured as a permanent magnetic material. By switching the magnetic pole direction of the electromagnet, the baffle 200 is driven in different directions. The specific process is not described in detail. Of course, the driver 400 can also be configured as a spring or other structure.

[0047] In some examples, the driving member 400 and the cushion block 300 are constructed on the same side. When the baffle 200 moves toward the driving member 400, the pushing action of the cushion block 300 can form a limiting effect on the movement of the baffle 200 toward the driving member 400, thereby reducing the impact between the driving member 400 and the baffle 200.

[0048] Next, how to reduce the collision between the driving member 400 and the blocking piece 200 will be described in detail.

[0049] Continue to combine Figure 1-Figure 2 In the example shown, when the baffle 200 moves in the opening direction and opens the first opening (i.e., when the baffle 200 switches from the second position to the first position), without the retaining structure of the spacer 300, the baffle 200 will collide with the driver 400. At this time, the driver 400 pushes against the baffle 200 after the collision and limits the baffle 200. As the baffle 200 repeatedly opens and closes within the chamber 110, it will repeatedly collide with the driver 400. Specifically, when the baffle 200 is opened, area C of the baffle 200 will repeatedly collide with the driver 400, causing damage to the baffle 200. This working environment and conditions can easily damage the baffle 200, shortening its service life.

[0050] Therefore, the driving member 400 and the pad 300 are both constructed in the opening direction of the baffle 200. The pad 300 arranged on the same side of the driving member 400 is suitable for pushing the baffle 200 and forming a limit for the baffle 200, preventing the baffle 200 from moving excessively in the opening direction to limit the movement range of the baffle 200, thereby avoiding or slowing down the collision between the baffle 200 and the driving member 400.

[0051] It can be understood that by providing the pad 300, the pushing effect formed by the baffle 200 and the pad 300 can share or assume the limitation of the baffle 200, thereby reducing or avoiding the wear of the baffle 200 during repeated opening and closing, thereby effectively improving the working environment and working conditions of the baffle 200, thereby extending the service life of the baffle 200 and extending the service life of the air valve.

[0052] In some embodiments, when the baffle 200 is in the first position, the distance between the baffle 200 and the cushion block 300 is a first distance, and the distance between the driving member 400 and the baffle 200 is a second distance. The second distance must be greater than or equal to the first distance to ensure that after the baffle 200 moves to the first position, the baffle 200 can form a pushing relationship with the cushion block 300.

[0053] Specifically, when the second distance is greater than the first distance, the pad 300 pushes against the baffle 200 and can assume the limiting function of the baffle 200; when the second distance is equal to the first distance, the pad 300 pushes against the baffle 200 and can share the limiting function of the baffle 200 in the opening direction.

[0054] Next, the above two situations are described in detail.

[0055] In some cases, when the blocking piece 200 is in the first position, the second distance is greater than the first distance, and the pad 300 pushes against the blocking piece 200 .

[0056] Because the distance between the driving member 400 and the blocking piece 200 exceeds the distance between the cushion block 300 and the blocking piece 200, the blocking piece 200 does not contact the driving member 400 when in the first position and is only pushed by the cushion block 300. Since the driving member 400 does not contact the blocking piece 200, the cushion block 300 actually assumes the role of pushing and limiting the blocking piece 200. In other words, when the blocking piece 200 moves in the opening direction, the cushion block 300 bears the impact caused by limiting the blocking piece 200.

[0057] In this case, the pad 300 can be made of a soft material, such as rubber, so that the pad 300 can absorb the impact and reduce the intensity of the impact, thereby reducing the damage to the baffle 200 during repeated opening and closing.

[0058] It can be understood that the pad 300 bears the impact caused by the movement of the baffle 200, thereby avoiding collision between the driving member 400 and the baffle 200, playing a role in protecting the driving member 400 and reducing the impact caused by the pad 300 limiting the baffle 200 by improving the structure or material of the pad 300, thereby extending the service life of the baffle 200.

[0059] In other cases, you can refer to Figure 1 As shown, the second distance is equal to the first distance, and the cushion block 300 and the driving member 400 are both pushed against the blocking piece 200 .

[0060] When the baffle 200 switches to the first position, since the distance between the pad 300 and the baffle 200 is equal to the distance between the driving member 400 and the baffle 200, the pad 300 and the driving member 400 push against the baffle 200 at the same time. At this time, the pad 300 actually shares the pushing and limiting effect of the baffle 200 with the driving member 400 and jointly bears the impact generated when the baffle 200 is limited.

[0061] Exemplary, reference Figure 1As shown, after the baffle 200 switches to the first position, the C region of the baffle 200 pushes against the driving member 400, and the baffle 200 also pushes against the cushion block 300. The C region and the cushion block 300 simultaneously form a limiting surface for the baffle 200, which increases the pressing area for limiting compared to the case where only the C region or only the cushion block is limiting.

[0062] It can be understood that by increasing the pushing area for limiting, the impact area generated when the baffle 200 switches to the first position for stopping can be increased, thereby evenly distributing the impact on the baffle 200 to various parts of the baffle 200, so that the stress generated by the impact is evenly distributed to avoid stress concentration, which can effectively reduce the degree of damage to the baffle 200 during opening and closing, thereby extending the service life of the baffle 200.

[0063] Next, the specific arrangement of the baffle 200 and the valve body 100 in some embodiments will be described.

[0064] In some embodiments, reference Figure 1-2 As shown, the side of the baffle 200 away from the airway 120 is the first wall 210, and the side facing the airway 120 is the second wall 220; a support portion 130 and a rebound portion 140 are also provided in the chamber 110; the support portion 130 pushes against the first wall 210, and the rebound portion 140 pushes against the second wall 220, and the rebound portion 140 and the support portion 130 are staggered along the length or width direction of the baffle 200.

[0065] For example, the driving member 400 is an electromagnet and the blocking piece 200 is a magnetic metal. The driving member 400 is adapted to drive the blocking piece 200 to switch from the second position to the first position, and the rebound portion 140 is adapted to rebound the blocking piece 200 from the first position to the second position. For example, the rebound portion 140 can be configured as any elastic component such as rubber or a spring.

[0066] Specifically, the rebound portion 140 pushes against one end of the baffle 200, while the other end of the baffle 200 is adapted to open and close the airway 120. The support portion 130 pushes between the two ends of the baffle 200, wherein the baffle 200 rotates along the support portion 130 to open and close the airway 120. In other words, because the rebound portion 140 and the support portion 130 are offset along the length or width of the baffle 200, the support portion 130 and the baffle 200 form a lever structure. The baffle 200 rotates along the support portion 130 to switch between the first and second positions. During this rotation, the support portion 130 serves as the rotational support point for the baffle 200 and is in continuous contact with the baffle 200, causing wear.

[0067] Therefore, when the baffle 200 is in the first position, the pad 300 pushes against the baffle 200 and forms a limit for the baffle 200, which can reduce the movement amplitude of the baffle 200 during the opening and closing process, thereby reducing the relative friction between the baffle 200 and the support portion 130 and thus reducing the wear of the baffle 200 during the opening process. Figure 1-Figure 2 The structure formed by the blocking piece 200 and the supporting portion 130 is described in detail with reference to an example.

[0068] The driving member 400 is provided on one side of the first wall 210 and is adapted to attract the baffle 200 to move toward the driving member 400 to switch from the second position to the first position. The baffle 200 rotates with the support portion 130 as the rotation center and is attracted by the driving member 400. Figure 2 The second position shown is rotated to Figure 1 First position shown.

[0069] The rebound portion 140 is provided on one side of the second wall 220, and the rebound portion 140 and the driving member 400 are respectively provided on both sides of the support portion 130. When the driving member 400 stops attracting the blocking piece 200, the rebound portion 140 pushes the blocking piece 200 in the opening direction, and the portion of the blocking piece 200 at the other end of the support portion 130 moves in the opposite direction relative to the push to the rebound portion 140 (i.e., moves from the first position to the second position), and the blocking piece 200 rotates with the support portion 130 as the rotation center and moves from Figure 1 The first position shown is rotated to Figure 2 The second position shown completes the switch from the first position to the second position.

[0070] It is understood that limiting the baffle 200 by the spacer 300 can shorten the swing stroke of the baffle 200 relative to the support portion 130, thereby reducing the relative friction between the support portion 130 and the baffle 200, thereby reducing wear of the baffle 200 in the support portion 130 area and extending the service life of the baffle 200. Furthermore, limiting the swing stroke of the baffle 200 can limit the overshoot vibration and tilting movement of the baffle 200 generated at the moment of being attracted by the electromagnet, thereby reducing the degree of damage to the baffle 200.

[0071] In addition, continue to refer to Figure 1-Figure 2 And further combine Figure 4 It is understood that in some embodiments, the end of the baffle 200 adjacent to the airway 120 is provided with a protrusion 230 extending toward the airway 120 . When the baffle 200 is in the second position, the protrusion 230 blocks the airway 120 from connecting to the end of the chamber 110 .

[0072] It can be understood that the protrusion 230 can cooperate with the first opening and form a blockage for the first opening, and due to errors during manufacturing and other reasons, the baffle 200 may deviate from the preset position when switching to the second position, resulting in insufficient travel of the baffle 200 to the first opening. At this time, the protrusion 230 can make up for the travel to complete the blocking function.

[0073] Specifically, the protrusion 230 is configured with a mating surface 231 facing the airway 120. The mating surface 231 is adapted to mate with the area of ​​the inner wall of the chamber 110 that is connected to the airway 120 to form a blockage on the opening. Specifically, when the baffle 200 is switched to the second position, the mating surface 231 is adapted to mate with the first opening to form a blockage.

[0074] Exemplary, reference Figures 1-4 As shown, the mating surface 231 is constructed as a bevel. Since the switching of the baffle 200 between the first position and the second position is a rotational movement centered on the support portion 130, when the baffle 200 rotates to the second position, a certain inclination angle is formed with the plane structure near the first opening. Constructing the mating surface 231 as a bevel is suitable for forming a blockage by cooperating with the first opening through the bevel when the baffle 200 switches to the second position.

[0075] Of course, in other examples, the mating surface 231 can be set according to the specific structure of the first opening, which will not be described here.

[0076] It can be understood that by cooperating with the mating surface 231 and the area where the first opening is located or directly with the first opening, the baffle 200 forms a good seal on the first opening, so that when the baffle 200 is in the second position, the baffle 200 can close the airway 120 and connect to one end of the chamber 110 (the first opening), thereby completing the sealing effect between the chamber 110 and the airway 120.

[0077] Next, combine Figure 3-Figure 6 The example shown is for Figure 1-Figure 2 The simplified structure shown is further explained.

[0078] First, combine Figure 3-Figure 4 The structure of the gas valve is described in detail.

[0079] The valve body 100 includes a first valve body 150 and a second valve body 160 that are spliced ​​together. The first valve body 150 and the second valve body 160 are spliced ​​together to define a chamber 110. The first valve body 150 is provided with an air inlet pipe 151, which is connected to the chamber 110. The second valve body 160 is provided with an air duct 120 that is connected to the chamber 110, and the second valve body 160 is also provided with a drainage groove 161 that is connected to the outside through an air outlet. Each air duct 120 is connected to a drainage groove 161, and the air outlets of the drainage grooves 161 are arranged regularly along a straight line.

[0080] The part of the airway 120 connected to the chamber 110 is the first opening. A baffle 200 is provided at the first opening to block the airway 120. The baffle 200 is a plate structure. The side of the baffle 200 away from the airway 120 is the first wall 210, and the side facing the airway 120 is the second wall 220.

[0081] The driving member 400 arranged in the chamber 110 is: an electromagnet formed into a columnar structure, which is referred to as a magnetic column for the sake of convenience. The block is constructed of magnetic metal. When power is turned on, the magnetic column produces an electromagnetic adsorption effect on the block, so that the block switches from the second position to the first position and then opens the first opening. Air can enter the corresponding air duct 120 from the gap between the block and the first opening, thereby controlling the air outlet work (or air intake work) of the air duct 120, and then accurately controlling the blowing position of the spray valve.

[0082] Furthermore, a support portion 130 and a rebound portion 140 are provided in the chamber 110 . The support portion 130 is pushed against the first wall 210 , and the rebound portion 140 is pushed against the second wall 220 .

[0083] Combine Figure 4 As shown, when the magnetic column attracts the blocking piece 200, the blocking piece 200 moves toward the magnetic column and simultaneously pushes against the pad 300 and the magnetic column. At this time, the blocking piece 200 switches from the second position to the first position, and the blocking piece 200 separates from the first opening to open the first opening.

[0084] When the magnetic column releases the blocking piece 200, the blocking piece 200 generates a lever action through the support portion 130 provided between the rebound portion 140 and the magnetic column, so that the rebound portion 140 presses against the second wall 220 so that the blocking piece 200 is pressed tightly against the first opening. Specifically, the rebound portion 140 presses against one end of the blocking piece 200, and the other end rotates and presses against the first opening.

[0085] Next, combine Figure 5-6 The matching relationship between the blocking piece 200 and the cushion block 300 is described in detail.

[0086] In this example, there are 10 air ducts 120, and each air duct 120 is provided with a set of baffles 200 and pads 300, so the corresponding structure has 10 sets of baffles 200 and pads 300, and the position of the pads 300 is adaptively arranged according to the setting position of the air duct 120 and the baffles.

[0087] Specifically, the first valve body 150 and the second valve body 160 are assembled and fixed by bolts 170. The first valve body 150 defines a portion of the chamber 110 and is in the shape of a rectangular parallelepiped. A number of magnets are constructed in the portion of the chamber 110 defined by the first valve body 150. The magnets are arranged around the inner wall of the chamber 110.
