DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] A fan controller with a long service life, such as Figure 1-Figure 5 As shown, it includes a shell 1, a speed regulator 2, a heat sink 3, a dust screen 4, a handle 41 and a synchronous moving mechanism 5. Four threaded holes are opened on the rear side of the shell 1. The shell 1 is installed on the wall through the threaded holes on the rear side of the shell 1. The shell 1 is fixedly connected with a speed regulator 2 for controlling the fan speed. The speed regulator 2 passes through the front side of the shell 1. The speed regulator 2 is electrically connected to the fan through the interface thereafter. Through holes are opened on the top and bottom of the shell 1. The heat sink 3 and the dust screen 4 are slidably connected in the through holes. The heat sink 3 has heat dissipation holes, and the dust screen 4 is located On the side close to the speed regulator 2, the dustproof nets 4 are aligned with the heat sink 3, and the corresponding heat sink 3 and dustproof nets 4 are tightly attached to each other, so that dust entering from the heat dissipation holes of the heat sink 3 can be directly blocked by the dustproof nets 4, preventing dust from entering the speed regulator 2 and affecting the heat dissipation effect of the fan controller. The front side of the dustproof nets 4 is fixedly connected with a handle 41, and the handle 41 can facilitate the movement of the dustproof nets 4. Two synchronous moving mechanisms 5 are connected inside the outer shell 1, and the two synchronous moving mechanisms 5 are symmetrically arranged on the left and right, and the upper and lower dustproof nets 4 are connected by the synchronous moving mechanism 5.

[0020] When the dustproof net 4 needs to be cleaned, move the upper and lower heat sinks 3 away from the outer shell 1. After removing the heat sink 3, move the dustproof net 4 through the handle 41 to keep the dustproof net 4 away from the outer shell 1. The synchronous moving mechanism 5 can be used to synchronously move the dustproof net 4 on one side while moving the dustproof net 4 on the other side. After cleaning, the two dustproof nets 4 are reset through the synchronous moving mechanism 5, and then the heat sink 3 is reset. When the speed regulator 2 is running, the heat can be dissipated through the heat dissipation holes on the heat sink 3. The speed regulator 2 has zero-point detection and shifting, and does not ignite, so it is not easy to damage the capacitor and protect the entire switch, preventing the speed regulator 2 from overheating and damaging electronic components. The dustproof net 4 can block dust from entering the outer shell 1 from the heat dissipation holes, thereby extending the service life of the fan controller.

[0021] like Figure 2-Figure 4As shown, the synchronous moving mechanism 5 includes a rotating plate 51, a first connecting rod 52, a second connecting rod 53 and a mounting block 54. The rotating plates 51 are rotatably connected on both sides of the outer shell 1. The first connecting rod 52 and the second connecting rod 53 are hinged on the sides where the left and right rotating plates 51 are close to each other. The first connecting rod 52 and the second connecting rod 53 are hinged on the sides away from the rotating plate 51. The mounting block 54 is connected to the dustproof net 4. The first connecting rod 52 is connected to the upper dustproof net 4 through the upper mounting block 54, and the second connecting rod 53 is connected to the lower dustproof net 4 through the lower mounting block 54. When picking up the upper dustproof net 4, the upper dustproof net 4 drives the first connecting rod 52 to move upward through the mounting block 54 thereon, and the upward movement of the first connecting rod 52 causes the rotating plate 51 to rotate, and the rotation of the rotating plate 51 drives the second connecting rod 53 to move downward, and the second connecting rod 53 drives the lower dustproof net 4 to move downward through the lower mounting block 54, and the same is true when the lower dustproof net 4 is pulled downward, so that when one side of the dustproof net 4 is pulled, the other side of the dustproof net 4 can be driven to move, so that the two dustproof nets 4 are simultaneously away from the outer casing 1, thereby facilitating the cleaning of the two dustproof nets 4 and ensuring the dustproof efficiency of the dustproof nets 4.

[0022] like Figure 2-Figure 4 As shown, the mounting block 54 is detachably connected to the dustproof net 4. When cleaning the dustproof net 4, the two dustproof nets 4 are simultaneously moved away from the housing 1 by the synchronous moving mechanism 5, and then the dustproof net 4 is removed from the mounting block 54, and the removed dustproof net 4 is cleaned, and then installed on the mounting block 54 after cleaning, thereby being able to clean the dustproof net 4 more carefully, avoiding stubborn impurities on the dustproof net 4 from affecting the dustproof efficiency of the dustproof net 4, and also facilitating the replacement of damaged dustproof nets 4.

[0023] like Figure 1 and Figure 4 As shown, a baffle 6 is also included. The bottom of the housing 1 is slidably connected with the baffle 6 for fixing the lower heat sink 3. The middle part of the baffle 6 is slender, so as not to affect the heat dissipation efficiency of the lower heat sink 3. When the lower heat sink 3 needs to be moved, the baffle 6 is slid away from the lower heat sink 3, and then the lower heat sink 3 is moved. When the lower heat sink 3 is slidably connected to the bottom of the housing 1, the baffle 6 is moved to contact the lower heat sink 3, so that the lower heat sink 3 can be fixed, and the housing 1 is prevented from being hit and causing the lower heat sink 3 to move downward and fall out of the housing 1.

[0024] like Figure 1 As shown, the fan controller also includes a display screen 7, and two display screens 7 are fixedly connected to the front side of the housing 1, and the display screen 7 is electrically connected to the speed regulator 2. When adjusting the speed of the fan, the corresponding gear information will be displayed on the display screen, so that the fan can be adjusted to a suitable gear. A temperature and humidity detector can also be installed in the fan controller, and then the temperature and humidity detector is electrically connected to the display screen 7, so that the temperature and humidity of the surrounding environment can be displayed on the display screen 7.

[0025] like Figure 1 , Figure 2 and Figure 5 As shown, it also includes a fixed block 8, a fixed rod 9, a slider 10 and an elastic member 11. The top of the housing 1 is fixedly connected to the fixed block 8, and a slide groove is opened on the rear side of the fixed block 8. The fixed rod 9 is fixedly connected in the slide groove. The slider 10 is slidably connected to the fixed rod 9. The elastic member 11 is fixedly connected between the slider 10 and the fixed block 8. The elastic member 11 is set as a spiral spring. Initially, the slider 10 is located above the heat sink 3. When it is necessary to clean the dust net 4, the slider 10 is moved forward to keep it away from the heat sink 3. The elastic member 11 is compressed. After removing the heat sink 3, the upper dust net 4 is moved upward, and the slider 10 is released. The elastic member 11 returns to its original state, so that the slider 10 moves backward to contact the bottom of the handle 41, thereby fixing the dust net 4, which is convenient for scraping off the dust on the dust net 4. After the dust net 4 is cleaned, the slider 10 is moved forward to reset the dust net 4 and the heat sink 3.

[0026] The technical principles of the embodiments of the present utility model are described above in combination with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present utility model, and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present utility model. Based on the explanations here, technicians in this field can think of other specific implementation methods of the embodiments of the present utility model without creative work, and these methods will fall within the protection scope of the embodiments of the present utility model.
