[0021] The present invention will be further described in detail below with reference to the accompanying drawings.
[0022] Reference Figure 1 , Figure 2 A fan temperature control and speed regulation module includes a controller housing 1. The controller housing 1 contains electrical components (not shown in the figure). The electrical components include a temperature sensor, a wind speed sensor, an actuator, an integrated circuit, a resistor, a capacitor, a time base oscillator, a diode, a transistor, and other components. It can realize fan temperature control and speed regulation. This is existing technology and will not be described in detail here.
[0023] Reference Figure 2 , Figure 3 The controller housing 1 has multiple heat dissipation vents 2 extending through it. Each heat dissipation vent 2 has a support ring 4 fixedly connected to it, and the support ring 4 is arranged circumferentially along the corresponding heat dissipation vent 2. Each heat dissipation vent 2 has a filter screen 3, and each support ring 4 has a stepped groove 5. The multiple filter screens 3 are respectively inserted into the corresponding stepped grooves 5, and the surface of the filter screen 3 is flush with the surface of the controller housing 1. At the same time, the multiple filter screens 3 are detachably connected to the corresponding support rings 4.
[0024] By incorporating a removable filter screen 3, operators can easily disassemble and clean it, facilitating cleaning and improving cleaning efficiency to ensure effective heat dissipation of the control module. Simultaneously, the support ring 4 features a stepped groove 5 for the filter screen 3 to engage, limiting its position and enhancing the stability of the connection between the filter screen 3 and the controller housing.
[0025] Reference Figure 2 , Figure 3 Four positioning posts 6 are vertically fixed to the bottom of the stepped groove 5, and the four positioning posts 6 are located at the four corners of the stepped groove 5. Positioning holes 7 are respectively provided through the four corners of the filter screen 3. The four positioning posts 6 are set one-to-one with the four positioning holes 7, and the positioning posts 6 can be inserted into the corresponding positioning holes 7, thereby limiting the installation position of the filter screen 3 and improving the limiting effect of the filter screen 3.
[0026] Reference Figure 2 , Figure 3The length of the positioning post 6 is the same as the depth of the positioning hole 7. Each of the four positioning holes 7 has a movably inserted fastening screw 8. Each of the four positioning posts 6 has a fastening groove 9, and the screw shank of the fastening screw 8 can be threaded into the fastening groove 9. When the fastening screw 8 is tightened, the nut of the fastening screw 8 can press the filter screen 3 firmly against the bottom of the stepped groove 5. This design allows the positioning post 6 to both define the installation position of the filter screen 3 and also serve as a connection point for the fastening screw 8, thus increasing its functionality.
[0027] Reference Figure 2 , Figure 3 An elastic shock-absorbing pad 10 is movably fitted onto the screw shank of the fastening screw 8. When the fastening screw 8 is tightened, the nut of the fastening screw 8 presses the shock-absorbing pad 10 firmly onto the filter screen 3. This design achieves isolation between the nut of the fastening screw 8 and the filter screen 3, reducing the risk of scratching the nut of the fastening screw 8 and damaging the filter screen 3.
[0028] Reference Figure 2 , Figure 3 An elastic sealing ring 11 is fixedly connected to the edge of the filter screen 3, and an annular sealing groove 12 is provided on the inner side wall of the stepped groove 5. The sealing ring 11 can be inserted into the sealing groove 12, thereby improving the sealing effect between the filter screen 3 and the controller housing 1 and reducing the risk of dust or debris entering the controller housing 1.
[0029] In this embodiment, the shock-absorbing pad 10 and the sealing ring 11 are made of rubber or latex material, respectively. Of course, in other embodiments, other elastic materials can also be used, which will not be listed in detail here.
[0030] Reference Figure 1 The filter screen 3 has a fluorocarbon layer on both sides to improve its self-cleaning effect, reduce the risk of dust or impurities sticking to the surface of the filter screen 3, and facilitate the cleaning of the filter screen 3 by the staff.
