[0038] To solve the above problems, such as Figures 1-3 As shown, an exemplary embodiment of this disclosure provides a wireless solenoid valve housing assembly, which may include: a first housing 10 and a second housing 20.

[0039] The first housing 10 may have a first mounting portion 121 formed inside for mounting the receiving coil. The first housing 10 may be a hollow housing for mounting the receiving coil. The first housing 10 may be made of plastic or a potting material such as epoxy resin to encapsulate the receiving coil inside the first housing 10. The first mounting portion 121 may be a cavity that matches the size and shape of the receiving coil, and the receiving coil may be disposed in the first mounting portion 121. The first housing 10 and the second housing 20 may be mated and detachably connected. The first housing 10 may have a positioning structure on its outer surface to facilitate positioning with the second housing 20; the first housing 10 may also have a fixing structure on its outer surface to facilitate fixing the first housing 10 and the second housing 20.

[0040] The second housing 20 has a second mounting portion 201 inside for mounting the transmitting coil. The second housing 20 is detachably connected to the first housing 10, and the second mounting portion 201 corresponds to the first mounting portion 121, allowing the receiving coil to receive the induced magnetic field emitted by the transmitting coil and generate an induced current. The second housing 20 can be a hollow housing for mounting the transmitting coil. The second housing 20 can be made of plastic or a potting material such as epoxy resin, which can encapsulate the transmitting coil inside the second housing 20. The second mounting portion 201 can be a cavity that matches the size and shape of the transmitting coil, and the transmitting coil can be disposed in the second mounting portion 201. The second housing 20 is detachably connected to the first housing 10. The wireless solenoid valve can include a transmitting circuit board and a receiving circuit board. The transmitting circuit board is connected to the transmitting coil and can be used to supply power to the transmitting coil so that the transmitting coil can generate an induced magnetic field. Therefore, the interior of the second housing 20 can also be used to install the transmitter circuit board. Since the transmitter coil and the transmitter circuit board are electrically connected, a connecting cavity can be provided within the second housing 20 between the transmitter coil and the transmitter circuit board for wiring. The interior of the first housing 10 can also be used to install the receiver circuit board. Since the receiver coil and the receiver circuit board are electrically connected, a connecting cavity can be provided within the first housing 10 between the receiver coil and the receiver circuit board for wiring. The second housing 20 can be provided with a positioning structure for mounting and positioning with the first housing 10. The second housing 20 can also be provided with a fixing structure to facilitate the fixed connection between the first housing 10 and the second housing 20. When the first housing 10 and the second housing 20 are fixedly connected, the first mounting part 121 of the first housing 10 and the second mounting part 201 of the second housing 20 can be correspondingly arranged so that the positions of the first mounting part 121 and the second mounting part 201 are aligned, so as to ensure that the receiving coil provided in the first mounting part 121 and the transmitting coil provided in the second mounting part 201 can be correspondingly arranged, so that the receiving coil can receive the induced magnetic field emitted by the transmitting coil and generate an induced current.

[0041] In this embodiment, the wireless solenoid valve housing assembly, through the first housing 10 and the second housing 20, separately sets up the receiver and transmitter of the wireless solenoid valve, facilitating the installation of the wireless solenoid valve. The mating connection between the first housing 10 and the second housing 20 aligns the first mounting portion 121 and the second mounting portion 201, ensuring that the receiver coil and the transmitter coil are aligned. This allows the receiver coil to receive the induced magnetic field emitted by the transmitter coil and generate an induced current, thereby ensuring the operational stability of the wireless solenoid valve.

[0042] In some embodiments, such as Figure 4 As shown, the first housing 10 may include: a main body 11 and an extension 12.

[0043] The main body 11 has a receiver circuit board mounting section 111 inside for mounting the receiver circuit board. The main body 11 may be a hollow cuboid shape. The receiver circuit board mounting section 111 can be formed inside the main body 11 for mounting the receiver circuit board. The receiver circuit board mounting section 111 can communicate with the first mounting section 121 to facilitate the interconnection between the receiver circuit board and the receiver coil. The receiver circuit board can control the opening and closing of the valve module of the wireless solenoid valve according to the induced current generated by the receiver coil. Therefore, the bottom end of the main body 11 can be used to connect with the valve module of the wireless solenoid valve.

[0044] The extension 12 has a first mounting portion 121 internally formed. The extension 12 is internally connected to the main body 11. A receiving end mating surface 122 is formed on one side of the extension 12 corresponding to the position of the first mounting portion 121. The extension 12 can be integrally formed with the main body 11. The extension 12 can be a shell structure formed by extending laterally from the main body 11. The first mounting portion 121 can be formed internally in the extension 12 for mounting the receiving coil. The extension 12 can be internally connected to the main body 11, allowing the first mounting portion 121 inside the extension 12 to connect with the receiving circuit board mounting portion 111 inside the main body 11, facilitating the connection between the receiving coil and the receiving circuit board. The receiving end mating surface 122 can be formed on one side of the extension 12 corresponding to the position of the first mounting portion 121, and can be used for alignment of the receiving coil and the transmitting coil. The thickness of the extension 12 can be less than the thickness of the main body 11. A stepped surface can be formed between the main body 11 and the extension 12 on the side where the extension 12 is located.

[0045] like Figure 5As shown, the outer side of the second housing 20 corresponding to the position of the second mounting portion 201 is formed as a transmitter mating surface 202, which is disposed opposite to the receiver mating surface 122. The second housing 20 may have a transmitter circuit board mounting portion 207 for mounting the transmitter circuit board inside. The second housing 20 may also include an extension portion, inside which a second mounting portion 201 may be formed. The second mounting portion 201 can communicate with the transmitter circuit board mounting portion 207, facilitating the connection between the transmitter coil and the transmitter circuit board. The thickness of the extension of the second housing 20 can be less than the thickness of the main body 11. The outer side of the second housing 20 corresponding to the position of the second mounting part 201 can be formed as a transmitter mating surface 202. The transmitter mating surface 202 can be used for the alignment of the receiver coil and the transmitter coil. The transmitter mating surface 202 can be arranged opposite to the receiver mating surface 122. The surface shape and area of ​​the transmitter mating surface 202 and the receiver mating surface 122 can be the same, thereby facilitating the installation of the transmitter mating surface 202 and the receiver mating surface 122, thereby aligning the receiver coil and the transmitter coil of the wireless solenoid valve and improving the operating stability of the wireless solenoid valve.

[0046] In some embodiments, such as Figures 4 to 7 As shown, the extension 12 can be located above the main body 11, in the middle of one side, or at the lower part of one side. Figure 6 As shown in (a), the main body 11 can extend in the vertical direction to form an extension 12. Figure 5 , Figure 6 As shown in (b), the second outer shell can mate with the extension 12 above the main body 11, thereby mates with and is fixedly connected to the first outer shell, so that the receiving end mating surface 122 and the transmitting end mating surface 202 are opposite to each other and abut against each other, and the top end of the second outer shell abuts against the upper end of the main body 11, thereby mates with the first outer shell. The upper part of the main body 11 can also extend outward in a horizontal direction along one side of the main body 11 to form an extension 12 (not shown in the figure), and the extension 12 can be fixedly connected to the side of the upper part of the main body 11.

[0047] like Figure 7As shown in (a), the extension 12 can be disposed in the middle of one side of the main body 11. The middle of the main body 11 can extend outward in a horizontal direction along one side of the main body 11 to form the extension 12. The extension 12 can be fixedly connected to the side of the main body 11 in the middle of the main body 11, and the upper part of the extension 12 can be partially connected to the main body 11. The second housing can cooperate with the extension 12 on the side of the middle of the main body 11, so that the second housing cooperates with and is fixedly connected to the first housing, so that the receiving end mating surface 122 and the transmitting end mating surface 202 are opposite to each other and abut against each other. The left end face of the second housing can abut against the end face of the main body 11 facing the extension 12. When the upper part of the extension 12 can be partially connected to the main body 11, the part of the main body 11 connected to the upper part of the extension 12 can abut against the upper end face of the second housing, so that the second housing cooperates with the first housing.

[0048] like Figure 7 As shown in (b), the extension 12 can be provided on the lower part of one side of the main body 11. The lower part of the main body 11 can extend outward in a horizontal direction along one side of the main body 11 to form the extension 12. The second housing can cooperate with the extension 12 on the lower side of the main body 11, so that the second housing cooperates with the first housing and is fixedly connected, so that the receiving end mating surface 122 and the transmitting end mating surface 202 are opposite to each other, and the top of the second housing abuts against the end face of the main body 11 facing the extension 12, so that the second housing cooperates with the first housing.

[0049] The extension 12 of the wireless solenoid valve provided in this disclosure can be installed in different positions to suit various scenarios. In some scenarios, a more compact installation structure is required, and wireless solenoid valves with different structures can be used according to different space requirements. On the other hand, wireless solenoid valve structures that are easy to install and disassemble can be selected according to different installation locations. This improves the applicability of the product.

[0050] Furthermore, the extension 12 of the wireless solenoid valve provided in this disclosure can be disposed in multiple locations, thereby allowing the receiving coil of the wireless solenoid valve to be disposed in different locations. Correspondingly, the positions of the transmitting coil and the receiving coil are also located in different locations. Multiple wireless solenoid valves with the extension 12 located in different locations can be arranged side by side to form a wireless solenoid valve group, ensuring that adjacent wireless solenoid valves do not interfere with each other. Specifically, since the induced magnetic field generated by the transmitting coil can radiate outward in space, if multiple wireless solenoid valves are arranged side by side and adjacent to each other, and the transmitting coil of one wireless solenoid valve is in the same position as the receiving coil of another adjacent wireless solenoid valve, it may cause the receiving coil of the other adjacent wireless solenoid valve to generate an induced current, resulting in the valve body opening incorrectly. In the embodiments of this disclosure, the extension 12 of the first housing 10 of the wireless solenoid valve can be located in different positions. When multiple wireless solenoid valves need to be arranged side by side, the wireless solenoid valves with extensions 12 located in different positions can be staggered, so that the receiving coils of adjacent wireless solenoid valves are misaligned, thereby greatly reducing the intensity of the induced magnetic field received by the transmitting coil of other wireless solenoid valves and avoiding excessively high induced current due to the induced magnetic field of other wireless solenoid valves.

[0051] In some embodiments, such as Figure 4 , Figure 5 As shown, the end face of the extension 12 away from the main body 11 may be provided with a first screw hole 123; the second housing 20 is provided with a second screw hole 203 corresponding to the first screw hole 123, for fixed connection with the extension 12 by screws. In this embodiment, the second housing 20 is aligned with the extension 12 of the first housing 10 and is detachably connected for easy replacement and installation. In practical applications, the extension 12 can be located in a relatively easily accessible position relative to the main body 11 to facilitate the installation and removal of the second housing 20. The first screw hole 123 is provided on the end face of the extension 12 away from the main body 11, and correspondingly, the second housing 20 is provided with a second screw hole 203, so that the screw connection can be easily removed and installed, and the installation position of the screw is convenient for operation, and it is also more convenient to screw it in or out in the direction away from the main body 11. Especially when multiple wireless solenoid valves are arranged side by side, there is sufficient space in the direction away from the main body 11.

[0052] In some embodiments, such as Figure 8As shown, the end face of the extension 12 away from the main body 11 may be provided with a boss 124 protruding in the direction away from the main body 11, and a first screw hole 123 is provided on the end face of the boss 124; a groove 204 is provided on the side of the second housing 20 facing the end face to accommodate the boss 124. In this embodiment, the extension 12 may have a boss 124 formed in the direction away from the main body 11, and the second housing 20 may have a groove 204 that mates with it, forming a positioning installation. The boss 124 can limit the second housing 20 in the longitudinal direction, thereby ensuring the alignment of the transmitting coil installed in the second housing 20 and the receiving coil installed in the extension 12, ensuring the stability and reliability of wireless power supply.

[0053] In some embodiments, such as Figure 9 As shown, the receiving end mating surface 122 of the extension 12 can be formed with a first groove 125; the transmitting end mating surface 202 of the second housing 20 is formed with a first protrusion 205, and the first protrusion 205 slides in conjunction with the first groove 125. In this embodiment, the receiving end mating surface 122 of the extension 12 can be formed with a first groove 125 in a direction away from the main body 11. The first groove 125 can be a recess formed by the receiving end mating surface 122, or it can be a groove formed between multiple ribs. Correspondingly, the second housing 20 is formed with a first protrusion 205, which can slide along the first groove 125, thereby allowing the second housing 20 to slide relative to the extension 12 in the extending direction of the first groove 125. When installing the second housing 20, the first protrusion 205 can be placed into the first groove 125, and the second housing 20 can be pushed to approach the main body 11. The second housing 20 abuts against the main body 11, reaching the installation position. When disassembling the second housing 20, it can be pulled outward. By setting the first sliding groove 125 and the first protrusion 205, installation and disassembly are more convenient and the movement is stable. It also ensures that the position of the transmitting coil can be aligned with the position of the receiving coil when the second housing 20 is moved into the final installation position.

[0054] In some embodiments, such as Figure 10 of (a), Figure 10As shown in (b), in some embodiments, the main body 11 is provided with a second groove 127, the extension direction of which is parallel to the receiving end mating surface 122; a second protrusion 208 is formed on the top of the second housing 20, and the second protrusion 208 is slidably engaged with the second groove 127. The main body 11 may have a second groove 127 on one side located at the top of the extension 12. Since the thickness of the extension 12 is half that of the main body 11, the second groove 127 may be located on the connecting surface between the main body 11 and the extension 12. On the side facing the receiving end mating surface 112, the top of the second housing 20 may have a second protrusion 208, which is slidably engaged with the second groove 127. In this embodiment, a second groove 127 may be formed at the portion of the extension 12 connected to the main body 11, and the second groove 127 may be parallel to the receiving end mating surface 122 and extend in a direction away from the main body 11. The longitudinal section of the second groove 127 can be trapezoidal, wider at the top and narrower at the bottom. The second groove 127 can be a recess formed by the main body 11, or a groove formed between multiple ribs. The second housing 20 can have a second protrusion 208 corresponding to the second groove 127. The second protrusion 208 can slide along the second groove 127, allowing the second housing 20 to slide relative to the main body 11 in the extending direction of the second groove 127. When installing the second housing 20, the second protrusion 208 can be inserted into the second groove 127, and the second housing 20 can be pushed to abut against the main body 11, so that the transmitting end mating surface of the second housing 20 is opposite to and correspondingly fitted with the receiving end mating surface of the first housing, aligning the receiving coil with the transmitting coil. When disassembling the second housing 20, it can be pulled outwards. By using the second slide groove 127 provided on the main body 11, the installation stability of the first housing and the second housing 20 can be ensured in the horizontal direction. The trapezoidal second slide groove 127, which is wider at the top and narrower at the bottom, and the second protrusion 208 provided on the second housing 20 that is paired with it, can ensure that the second housing 20 is engaged with the first housing. The second slide groove 127, which is wider at the top and narrower at the bottom, can fix the second protrusion 208. In the vertical direction, the first housing 10 and the second housing 20 are engaged and fixed, preventing the second housing 20 from falling vertically, thus ensuring the installation stability in the vertical direction. This ensures the relative fixation between the first housing and the second housing 20, thereby ensuring that the position of the transmitting coil can be aligned with the position of the receiving coil, with a moderate and relatively fixed distance.

[0055] In some embodiments, such as Figure 11 of (a), Figure 11As shown in (b), a stop 112 may be provided in the extension direction of the main body 11 towards the extension 12. The stop 112 is opposite to and spaced apart from the receiving end mating surface 122. The second housing 20 is at least partially disposed between the receiving end mating surface 122 and the receiving end mating surface 122. In this embodiment of the present disclosure, the main body 11 may have a protruding stop 112. The inner side of the stop 112 is opposite to the extension 12, which allows the second housing 20 to be better positioned when moved to the installation position. This restricts the movement of the inner end of the second housing 20 (i.e., the end closer to the main body 11) away from the receiving end of the extension 12, ensuring that the second housing 20 is close enough to or fits the extension 12, and preventing the second housing 20 from falling off during use, thereby improving installation reliability.

[0056] In some embodiments, such as Figure 12 of (a), Figure 12 As shown in (b), the lower part of the stop 112 may be provided with a first protrusion 113 protruding toward the receiving end mating surface 122; the second housing 20 is formed with a second protrusion 206 that mates with the first protrusion 113, and the bottom surface of the second protrusion 206 is disposed opposite to the top surface of the first protrusion 113. In this embodiment of the present disclosure, the stop 112 may also be formed with a first protrusion 113 that abuts against the second protrusion 206 of the second housing 20, thereby restricting longitudinal movement at the inner end of the second housing 20 (i.e., the end near the main body 11), enabling better positioning and installation, and ensuring that the receiving end coil and the transmitting end coil are aligned.

[0057] In some embodiments, such as Figure 13As shown, the first housing 10 may include a positioning part 13, disposed on one or both sides of the main body 11, located at the upper, middle, or lower part of the main body 11. The positioning part 13 can be used to position and install the wireless solenoid valve on the valve plate, improving the reliability of the installation position. On the other hand, by setting the positioning part 13 at different positions, it can be applied to more scenarios. In practical applications, multiple wireless solenoid valves can be arranged side by side and installed on the valve plate to facilitate fixing the wireless solenoid valves and installing the wireless solenoid valve assembly in the pipeline system. The first housing 10 of the multiple wireless solenoid valves may have an outwardly protruding positioning part 13 formed in a direction perpendicular to the outer surface of the first housing 10. The positioning part 13 can be used to position and install the first housing 10 on the valve plate, thereby fixing the wireless solenoid valves and preventing relative movement of the wireless solenoid valves in the wireless solenoid valve assembly. The positioning part 13 may have a threaded hole, and screws can be passed through the threaded hole of the positioning part 13 to install it on the valve plate. The positioning part 13 can be located at the upper part of the outer surface of the first housing 10. The positioning part 13 can protrude outward along the outer surface of the first housing 10 and extend to both sides in a strip shape. The wireless solenoid valve can be positioned and installed on the valve plate through the positioning part 13. The positioning part 13 can be provided with threaded holes for mounting screws to fix it to the valve plate. The threaded holes can be provided along the extension direction of the positioning part 13. When fixing the wireless solenoid valve to the valve plate through the positioning part 13, the positioning part 13 can be perpendicular to the valve plate. The wireless solenoid valve is fixedly installed on the valve plate surface by passing screws through the threaded holes of the positioning part 13 and the holes provided on the valve plate. The positioning part 13 can also be located in the middle of the outer surface of the first housing 10, protruding outward from the middle of the outer surface of the first housing 10. The protruding positioning part 13 can extend to both sides in a strip shape and can be provided with threaded holes provided along the extension direction of the positioning part 13 for mounting screws to fix the wireless solenoid valve to the valve plate. The positioning part 13 can also be located at the lower part of the outer surface of the first housing 10. The positioning part 13 can be provided on one side of the outer surface of the first housing 10, or it can be provided on both sides of the outer surface of the first housing 10. The first positioning part and the second positioning part respectively provided on both sides of the outer surface of the first housing 10 can be provided at the upper, middle or lower part of the outer surface of the first housing 10. This allows the wireless solenoid valve to have different positioning part positions according to the different positions of the receiving coil. This means that wireless solenoid valves with different receiving coil positions that are adjacent to each other will have different positioning part positions. When installing the wireless solenoid valve on the valve plate, the different wireless solenoid valves can be distinguished by the position of the positioning part, avoiding installation errors.

[0058] In some embodiments, such as Figure 1 , Figure 4 , Figure 7As shown, the wireless solenoid valve housing assembly may further include a valve housing 30, disposed below the main body 11, for mounting the valve body. In this embodiment, the connection between the wireless solenoid valve and the fluid circuit can be controlled by opening and closing the valve body, thereby enabling the wireless solenoid valve to control the opening and closing of the fluid circuit and the flow direction. The valve body can be electrically connected to the receiving circuit board. An induced current is generated by the receiving coil based on the induced magnetic field, and the valve body is energized and energized through the receiving circuit board to control the opening and closing of the valve body. The valve housing 30 can be installed below the main body 11, and its interior is connected to the main body 11 for electrical connection between the receiving circuit board and the valve body. The valve housing 30 may also have one or more through holes for the inlet and outlet of the fluid pipeline. For example, the valve housing 30 may have two through holes, one for an inlet pipe connected to the valve body, and the other for an outlet pipe connected to the valve body. The inlet pipe is connected to an air source for supplying air. The outlet pipe can be connected to a nozzle of a sorting device, and the opening of the valve body enables the nozzle to spray air to sort materials.

[0059] In some embodiments, such as Figure 4 , Figure 14As shown, the valve housing 30 may include a valve mounting portion 31, which is located on one or both sides of the outer surface of the valve housing 30, at the upper, middle, or lower part of the outer surface of the valve housing 30. Since the wireless solenoid valve assembly consists of multiple wireless solenoid valves arranged in parallel, in practical applications, multiple wireless solenoid valves can be arranged side-by-side and mounted on a valve plate to facilitate fixing the wireless solenoid valves and installing the wireless solenoid valve assembly in a piping system. The valve housing 30 of the multiple wireless solenoid valves may have an outwardly protruding valve mounting portion 31 formed in a direction perpendicular to the outer surface of the housing. The valve mounting portion 31 can be used to position and mount the receiving module on the valve plate, thereby fixing the wireless solenoid valves and preventing relative movement of the wireless solenoid valves in the wireless solenoid valve assembly. The valve mounting portion 31 may have a threaded hole, allowing screws to pass through the threaded hole and be mounted on the valve plate. The valve mounting portion 31 may be located at the upper, middle, or lower part of the outer surface of the valve housing 30. The valve mounting part 31 can be located on one side of the outer surface of the valve housing 30, or on both sides of the outer surface of the valve housing 30. The first valve mounting part 31121 and the second valve mounting part 31201 located on both sides of the outer surface of the valve housing 30 can be located on the upper, middle, or lower part of the outer surface of the valve module housing, respectively. The valve mounting part 31 on one side of the wireless solenoid valve is located on the lower part of the outer surface of the valve housing 30, and the valve mounting part 31 on the other side of the outer surface of the valve housing 30 can be located on the upper part of the valve module. The valve mounting part 31 can be positioned differently depending on the location of the receiver coil of the wireless solenoid valve. This means that adjacent wireless solenoid valves with different receiver coil positions will have different positions for their valve mounting parts 31. For the first type of solenoid valve, the valve mounting part 31 is located on the lower part of the left side and the upper part of the right side of the valve module, while for the second type of solenoid valve, the valve mounting part 31 is located on the upper part of the left side and the lower part of the right side of the valve module. When installing the wireless solenoid valve on the valve plate, the different wireless solenoid valves can be distinguished by the position of the valve mounting part 31, thus avoiding installation errors.

[0060] Based on the same inventive concept, this disclosure also provides a wireless solenoid valve 100, which may include: a wireless solenoid valve 100 housing assembly as described in any of the above embodiments; a transmitting coil disposed in a second mounting portion 201; and a receiving coil disposed in a first mounting portion 121, for receiving the induced magnetic field emitted by the transmitting coil and generating an induced current. The first housing 10 and the second housing 20 allow for convenient installation and disassembly, and ensure that the transmitting coil and the receiving coil are aligned, thereby improving the reliability and stability of wireless power supply.

[0061] Based on the same inventive concept, such as Figure 15As shown, this disclosure also provides a wireless solenoid valve assembly, including: a plurality of wireless solenoid valves 100 arranged side by side as in any of the above embodiments. In this disclosure, the plurality of wireless solenoid valves 100 can be arranged side by side to form a wireless solenoid valve assembly. Furthermore, by staggering the wireless solenoid valves 100 at different positions of the extension 12, interference problems between adjacent wireless solenoid valves 100 can be avoided.

[0062] For example, the wireless solenoid valve 100 can be used in a material sorting machine. The sorting machine can be used to sort various materials and may include a conveying device, an identification device, and a sorting device. The conveying device transports the materials to be sorted to the identification device, which detects and identifies the materials to be sorted, determining their classification. The sorting device then sorts the materials according to their classification. The sorting device may include a blowing assembly and a pushing assembly. The blowing assembly blows airflow onto the materials to be rejected, removing them from the collection. The pushing assembly pushes the materials to be rejected using a pusher plate, removing them from the collection. The blowing assembly may include multiple nozzles arranged side-by-side. Since the sorting machine can sort smaller particles, the nozzles are spaced close together to ensure high sorting accuracy for smaller particles. The blowing assembly can be controlled by a wireless solenoid valve group. The gas flow path of each nozzle can be controlled by a corresponding wireless solenoid valve 100. Since the spacing between the multiple nozzles arranged side by side is small, the wireless solenoid valves 100 used to control the blowing function of each nozzle are arranged side by side according to the position of the nozzle, and each wireless solenoid valve 100 is close to each other. In the wireless solenoid valve group, the spacing between each wireless solenoid valve 100 is small and the arrangement is dense.

[0063] The embodiments of this disclosure can include at least a row of multiple wireless solenoid valves 100 arranged side by side. These multiple wireless solenoid valves 100 can be arranged closely together. This disclosure can reduce the leakage of the induced magnetic field at the transmitting end or reduce the degree to which the receiving end is affected by other induced magnetic fields, thus ensuring that the closely arranged wireless solenoid valves 100 do not interfere with each other. The distance between adjacent wireless solenoid valves 100 can be less than or equal to 60mm, or less than 30mm, or even placed very close together. This allows for application in scenarios such as the aforementioned sorting machines, facilitating installation and replacement and reducing costs. For example, by controlling the spray assembly of a sorting machine through a wireless solenoid valve group, the wireless solenoid valves 100 can be arranged side by side according to the position of the nozzle. Multiple parallel wireless solenoid valves 100 can be connected one-to-one with a nozzle, and each wireless solenoid valve 100 can be close to each other. However, the receiving coil of any wireless solenoid valve 100 is not affected by the induced magnetic field generated by the transmitting coil of other wireless solenoid valves 100 when opening or closing the valve body. The wireless solenoid valves 100 are closely spaced and densely arranged, with the spacing between adjacent wireless solenoid valves 100 being less than 60mm. In some cases, the spacing between adjacent wireless solenoid valves 100 can be less than 30mm. With such a small spacing, each wireless solenoid valve 100 in the wireless solenoid valve group has high anti-interference capability. The receiving coil of any one wireless solenoid valve 100 is not affected by the induced magnetic field generated by the transmitting coil of other wireless solenoid valves 100 when opening or closing the valve body.

[0064] The receiving coils of the wireless solenoid valve 100 can be arranged alternately, and two types of wireless solenoid valves 100 can be selected with their receiving coils located in different positions. The two types of wireless solenoid valves 100 can be arranged alternately. For example, a first solenoid valve with its receiving coil located at the top of the receiving module and a second solenoid valve with its receiving coil located at the bottom of the receiving module can be selected. Alternating between the first and second solenoid valves can reduce interference between the wireless solenoid valves 100. In addition, only two types of wireless solenoid valves are selected to form a wireless solenoid valve group, which facilitates the installation of the wireless solenoid valves 100 and reduces costs. Alternatively, the three types of wireless solenoid valves 100 can be alternately arranged. For example, a first solenoid valve with its receiving coil located at the top of the receiving module, a second solenoid valve with its receiving coil located at the bottom of the receiving module, and a third solenoid valve with its receiving coil located in the middle of the receiving module can be selected. The wireless solenoid valves 100 are installed on the valve plate in the order of the first solenoid valve, the second solenoid valve, and the third solenoid valve to form a wireless solenoid valve group. Since the wireless solenoid valves 100 with their receiving coils located in the same position can be spaced two different wireless solenoid valves 100 apart, the distance between the wireless solenoid valves 100 with their receiving coils located in the same position is greater, which can more significantly reduce the electromagnetic interference between every two wireless solenoid valves 100 with their receiving coils located in the same position, and effectively reduce the electromagnetic interference inside the wireless solenoid valve group.

[0065] By setting multiple wireless solenoid valves 100 with different receiving coil positions, the receiving coils of adjacent wireless solenoid valves 100 are staggered vertically, which can reduce electromagnetic interference between adjacent wireless solenoid valves 100 when controlling strong electromagnetic field changes, ensure the independent operation of each solenoid valve in the wireless solenoid valve group, improve the anti-interference ability of each wireless solenoid valve 100 in the wireless solenoid valve group, and improve the reliability and stability of the wireless solenoid valve group.

[0066] Based on the same inventive concept, embodiments of this disclosure also provide a sorting device, which may include: a plurality of nozzles arranged side by side; and a wireless solenoid valve assembly as in any of the above embodiments, wherein each wireless solenoid valve 100 is connected to a nozzle for controlling the start and stop of the nozzle. The wireless solenoid valve assembly of embodiments of this disclosure can save space, reduce costs, and improve the reliability of nozzle blowing in the sorting device.
