[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Reference Figure 1 , Figure 4 - Figure 7 The utility model provides an embodiment: a fan controller that is easy to assemble, including a lower cover 1, the inner wall of the lower cover 1 is provided with a quick installation mechanism, the quick installation mechanism includes a fixing member 6, the inner wall of the fixing member 6 is elastically connected with a column 9 through a spiral spring 8, and the column 9 is kept rotating outward without being affected by external forces by the elastic force of the spiral spring 8. The outer wall of the column 9 is rotatably connected to the inner wall of the fixing member 6, so that the column 9 can rotate along the inner wall of the fixing member 6, and the outer wall of the column 9 is fixedly connected with a clamping rod 7, so that the column 9 can drive the clamping rod when rotating. 7 always keeps rotating outward and keeps the fixing member 6 in a vertical state. The outer wall of the clamping rod 7 is rotatably connected to the inner wall of the fixing member 6, so that the clamping rod 7 can rotate along the inner wall of the fixing member 6. The outer wall of the clamping rod 7 is clamped with the circuit board 2, so that the circuit board 2 can be fixed to the inner wall of the lower cover 1 by clamping with the clamping rod 7. The inner wall of the lower cover 1 is provided with a sliding groove 5, so that the fixing member 6 can move laterally on the inner wall of the lower cover 1. The inner wall of the sliding groove 5 is slidably connected to the bottom end of the fixing member 6, so that the fixing member 6 can always move laterally along the inner wall of the sliding groove 5.

[0035] Reference Figure 1 - Figure 2 The top of the lower cover 1 is fixedly connected to the plastic shell 3, so that the plastic shell 3 can be fixed to the top of the lower cover 1. The outer wall of the plastic shell 3 is clamped with a buckle 10, so that the buckle 10 can be fixed to the outer wall of the plastic shell 3 by clamping. The top of the buckle 10 is fixedly connected to the upper cover 4, so that when the buckle 10 is clamped with the outer wall of the plastic shell 3, the upper cover 4 can be fixed to the top of the plastic shell 3. The inner wall of the upper cover 4 is plugged into the top of the plastic shell 3, so that the upper cover 4 can be fixed to the top of the plastic shell 3.

[0036] Reference Figure 1 - Figure 3 The outer wall of the plastic shell 3 is fixedly connected with a fixing plate 11, and the outer wall of the plastic shell 3 provides a fixed support for the fixing plate 11. The inner wall of the fixing plate 11 is penetrated and slidably connected with bolts, so that the fixing plate 11 can be fixed to the wall or other fixed surface by bolts, and at the same time, the whole device is fixed to the wall or fixed surface.

[0037] Reference Figure 5 , Figure 7 One end of the spiral spring 8 is fixedly connected to the inner wall of the fixing piece 6, and the other end of the spiral spring 8 is fixedly connected to the outer wall of the column 9, so that when the circuit board 2 is plugged into the clamping rod 7, the clamping rod 7 shrinks inward due to the compression of the inclined surface. When it is plugged into the specified position, the clamping rod 7 will be immediately reset due to the elastic force of the spiral spring 8, and at the same time, the clamping rod 7 clamps the circuit board 2, so that the circuit board 2 can be fixed to the inner wall of the lower cover 1.

There are four groups of buckles 10, so that the connection between the upper cover 4 and the plastic shell 3 can be more stable.

[0039] Working principle: When installing the device, first move the four groups of fixing parts 6 horizontally along the slide groove 5 to the appropriate position, then align the plug-in hole of the circuit board 2 with the top of the fixing part 6 and press down, then the clamping rod 7 will shrink inward due to the squeezing of the inclined surface, and when plugged into the specified position, the clamping rod 7 will immediately reset due to the elastic force of the spiral spring 8, and at the same time make the clamping rod 7 clamp the circuit board 2, so that the circuit board 2 can be fixed on the inner wall of the lower cover 1, and then fix the plastic shell 3 to the top of the lower cover 1, and then fix the upper cover 4 to the top of the plastic shell 3 through the four groups of buckles 10, and then pass the bolts through the fixing plate 11, and fix the bottom end of the bolts to the wall or the fixed surface, so that the entire device is fixed on the wall or the fixed surface.
