[0002] In fields such as industrial dust removal, pneumatic control, and automated production lines, pulse solenoid valve controllers are the core devices that drive solenoid valves to achieve precise opening and closing. The stability and maintainability of their control motherboard directly affect the system's operating efficiency. Currently, most pulse solenoid valve controllers on the market use a housing-encapsulated form to install the control motherboard. While this design provides basic protection, in actual operation and maintenance scenarios, the inconvenience caused by the limited internal space of the housing is becoming increasingly prominent.

[0003] The existing pulse solenoid valve controller's main control board is installed inside a housing. However, the limited space inside the housing makes it difficult for personnel to repair the main control board, and maintenance personnel need tools to remove the housing cover, which is inconvenient. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a pulse solenoid valve controller that is easy to maintain. This solves the technical problem that the control motherboard of the current pulse solenoid valve controller is installed inside the housing, which has a small internal space, making it inconvenient for personnel to repair the control motherboard inside the housing. Furthermore, maintenance personnel need tools to remove the housing cover, which is quite inconvenient.

[0005] To achieve the objective of this utility model, the technical solution adopted is as follows: A pulse solenoid valve controller that is easy to maintain is designed, comprising:

[0006] The housing has a U-shaped structure and a control motherboard is installed inside its cavity;

[0007] Two side plates are symmetrically hinged to the open ends of the shell on both sides by hinges. The side plates can rotate about the hinge axis to realize the opening and closing of the sides of the shell.

[0008] A cover, detachably mounted between the tops of the two side panels, is used to close the top opening of the housing;

[0009] A quick-release connection mechanism is located at the joint between the cover and the side panel to enable a detachable connection between the cover and the side panel, facilitating convenient maintenance of the control board.

[0011] Wedge-shaped blocks are fixedly connected to the four corners of one end of the cap;

[0012] Wedge-shaped grooves are provided on both sides of the two side plates near the end of the cover, and the wedge-shaped blocks correspond to and are adapted to the wedge-shaped grooves;

[0013] The anti-slip pad is fixedly attached to the outside of the wedge block to increase the friction between the wedge block and the wedge groove.

[0014] Preferably, the inner cavity of the housing is fixedly connected to four support columns, the control main board is disposed on the top of the four support columns, a fixing bolt passes through the control main board, and the fixing bolt is threadedly connected to the surface of the support column.

[0015] Preferably, baffles are fixedly connected to the inner walls of the openings at both ends of the housing, and the distance between two baffles on the same side is less than the length of the side plate.

[0016] Preferably, the housing has an air inlet and an exhaust port at its two ends away from the side plate, and a fan is fixedly installed in the air inlet.

[0017] Preferably, the inner walls of both the air inlet and the exhaust outlet are fixedly connected with filter screens, and the filter screen in the air inlet does not contact the fan.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0031] Example 1: A pulse solenoid valve controller that is easy to maintain, see [link to example]. Figures 1 to 6 ,include:

[0032] The housing 1 has a U-shaped structure and a control main board 4 is provided in its inner cavity;

[0033] Two side plates 11 are symmetrically hinged to the open ends of the housing 1 on both sides by hinges. The side plates 11 can rotate around the hinge axis to realize the opening and closing of the side of the housing 1.

[0034] The cover 2 is detachably disposed between the tops of the two side plates 11 to close the top opening of the housing 1;

[0035] A quick-release connection mechanism is provided at the joint between the cover 2 and the side plate 11 to enable the detachable connection between the cover 2 and the side plate 11, so as to facilitate the maintenance of the control board 4.

[0036] During operation, the housing 1, cover 2, quick-release connection mechanism, and hinged side plates 11 are configured such that after the cover 2 is opened, the two side plates 11 can rotate freely around the hinges to open and close, effectively solving the problem of inconvenient maintenance operations caused by the small internal space of the housing 1 in existing controllers. With the quick-release connection mechanism between the top cover 2 and the side plates 11, the traditional fastening methods such as screws and clips that require tools are eliminated. The cover 2 can be quickly installed and removed by manual operation, which greatly shortens the maintenance preparation time and significantly improves the convenience and efficiency of equipment maintenance. It effectively avoids the problems of high maintenance costs and long downtime caused by the cumbersome disassembly of traditional controllers.

[0037] For details, see Figure 3 and Figure 6 The quick-release connection mechanism includes: wedge blocks 22, fixedly connected to the four corners of one end of the cover 2; wedge grooves 24, located on both sides of the two side plates 11 near the end of the cover 2, with the wedge blocks 22 and wedge grooves 24 corresponding and compatible; and anti-slip pads 23, fixedly connected to the outside of the wedge blocks 22, used to increase the friction between the wedge blocks 22 and the wedge grooves 24. During operation, the wedge blocks 22 at the four corners of the cover 2 and the wedge grooves 24 of the side plates 11 achieve precise docking and locking through the inclined plane guiding principle. During installation, it can automatically align and position itself, and during disassembly, it can be separated by applying vertical force, completely eliminating the dependence on tools such as screwdrivers and wrenches, and thoroughly solving the drawbacks of traditional controllers that "tools are required to remove the cover and the operation steps are cumbersome". The anti-slip pads 23 on the outside of the wedge blocks 22 increase the contact friction, preventing the cover 2 from accidentally loosening due to vibration or collision during equipment operation, and ensuring the sealing and protection of the control motherboard 4 inside the housing 1.

[0038] Further, see Figure 5The inner cavity of the housing 1 is fixedly connected to four support columns 42. The control main board 4 is located on top of the four support columns 42. A fixing bolt 41 passes through the control main board 4, and the fixing bolt 41 is threadedly connected to the surface of the support column 42. Air inlet 33 and exhaust 32 are respectively opened at the two ends of the housing 1 away from the side plate 11. A fan 31 is fixedly installed in the air inlet 33. The control main board 4 is raised to the middle space of the housing 1 by the support columns 42. This not only avoids the problem of bottom cable obstruction caused by traditional flat installation, but also, together with the fan 31, allows air to enter from the air inlet 33 and flow through the control main board. After board 4, the air is discharged through exhaust port 32, forming a complete heat dissipation channel of "intake port 33 → bottom and surrounding three-dimensional space of control motherboard 4 → exhaust port 32". Fan 31 drives air to be drawn in from the bottom air intake port 33 of the housing 1. After being lifted, the air flows evenly across the surface of the circuit board in the overhead area below the control motherboard 4, which fully removes the heat generated by the components during operation. The air is then discharged outside the housing 1 through the top or side exhaust port 32. This three-dimensional heat dissipation channel design greatly increases the contact area and flow efficiency between the air and the control motherboard 4, significantly reduces the accumulation of heat inside the housing 1, and thus improves the heat dissipation effect of the control motherboard 4.

[0039] It is worth noting that, see Figure 5 The inner walls of the openings at both ends of the housing 1 are fixedly connected with baffles 13. The distance between the two baffles 13 on the same side is less than the length of the side plate 11. By setting the baffles 13, the rotation and closing angle of the side plate 11 can be controlled, avoiding hinge fatigue or deformation of the side plate 11 caused by excessive closing. At the same time, it provides stable support for the side plate 11 and improves the stability of the side plate 11 closing.

[0040] It is worth noting that, see Figure 1 , Figure 2 and Figure 5 The inner walls of the air inlet 33 and the exhaust 32 are both fixedly connected with filter screens 3. The filter screen 3 in the air inlet 33 does not contact the fan 31. The filter screen 3 can effectively intercept dust, particles and other impurities in the air, preventing them from entering the housing 1 and adhering to the control motherboard 4 or the surface of electronic components. This avoids the risk of short circuits or reduced heat dissipation efficiency caused by dust accumulation in traditional controllers. The design of maintaining a distance between the filter screen 3 in the air inlet 33 and the fan 31 ensures smooth airflow and provides operating space for disassembling and cleaning the filter screen 3. This improves the dustproof performance of the equipment, takes into account the convenience of maintenance, and extends the service life of internal components.

[0041] It is worth mentioning that, see Figure 5The end of the baffle 13 near the side plate 11 and the end of the cover 2 near the baffle 13 are both fixedly connected with a sealing gasket 14. The sealing gasket 14 is elastic. When the side plate 11 is closed, the sealing gasket 14 is squeezed and deformed to fill the gap between the side plate 11 and the baffle 13, as well as the gap between the cover and the side plate 11 and the housing 1, thereby effectively preventing external dust from entering the interior of the housing 1.

[0042] It is worth mentioning that, see Figure 1 The housing 1 has wire holes 12 on both sides near the air inlet 33. The inner wall of the wire hole 12 is fixedly connected with an elastic rubber ring. The wire hole 12 and the elastic deformation of the rubber ring allow the cable to be flexibly inserted, while tightly wrapping the cable sheath. This avoids the cable wear problem caused by the rigid edge of the traditional wire hole 12, and effectively prevents external dust from entering the housing 1 through the wire hole 12.

[0043] It is worth mentioning that, see Figure 2 The cover 2 has finger grooves 21 at both ends, and the finger grooves 21 are symmetrically distributed at both ends of the cover 2. The finger grooves 21 facilitate the insertion of fingers by personnel, thereby facilitating the application of a force perpendicular to the cover 2 to disassemble the cover 2.

[0044] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

[0045] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
