In this way, from the outside, only the shell 100 and the outer cover 210 can be seen, but the control module inside the shell 100 and the control module inside the outer cover 210 cannot be seen. The appearance of the shell 100 and the outer cover 210 can be set as needed to achieve a more beautiful effect.

[0026] In some embodiments, the control module includes a first circuit board on which a control circuit is disposed. The control circuit is respectively connected to the controlled device and the indication module to achieve control and protection of the controlled device and control of the indication module.

[0027] In some embodiments, the indication module includes a second circuit board, on which an indication circuit and an indication element are provided. The second circuit board is fixedly connected to the outer cover 210, the indication circuit is electrically connected to the indication element, and the control circuit is electrically connected to the indication circuit. In this way, the control circuit can control the indication element through the indication circuit so that the indication element sends an indication signal.

[0028] In some embodiments, the indicating element may be a light source, a sound device, or any other suitable combination of one or more of the controlled devices. When the indicating element is a light source, the indicating device is a light indicating device, and when the indicating element is a sound device, the indicating device is a sound indicating device. When the indicating element is a light source, the outer cover 210 may be a light-transmitting device, so that the light signal emitted by the indicating element can be emitted outward through the outer cover 210, so that the user can observe it.

[0029] In some embodiments, at least one fixing member 220 is provided on the inner side of the outer cover 210, and a first slot 221 is provided on the fixing member 220. One side of the second circuit board can be inserted into the first slot 221 to be fixed on the fixing member 220. In this way, the second circuit board can be fixed in the second inner cavity 211 to prevent the second circuit board from shaking.

[0030] The number of the fixing members 220 can be set as needed, preferably two, so that the two sides of the second circuit board can be respectively inserted into the first slots 221 on the two fixing members 220, so that the second circuit board can be more firmly fixed on the outer cover 210.

[0031] In some embodiments, the fixing member 220 includes a first fixing portion 222 and a second fixing portion 223, the second fixing portion 223 is fixed to the inner side of the outer cover 210, the first fixing portion 222 is fixed to the second fixing portion 223, and the outer side of the housing 100 may be provided with a second card slot 110 that matches the second fixing portion 223 of the fixing member 220, and the second fixing portion 223 may be inserted into the second card slot 110 to achieve positioning and pre-fixation of the outer cover 210 and the housing 100. Exemplarily, the second card slot 110 may be formed between protrusions provided on the outer side of the housing 100, and when the second fixing portion 223 is inserted into the second card slot 110, the two protrusions may limit the second fixing portion 223.

The shape of the protrusion 120 is the same as the opening of the outer cover 210, and its size is slightly smaller than the opening of the shell 100. In this way, the protrusion 120 can be inserted into the second inner cavity 211 of the outer cover 210 and limit the outer cover 210, thereby preliminarily positioning the outer cover 210.

[0033] In some embodiments, the fixing member 220 can also be fixed to the housing 100 by screws, so that the outer cover 210 is fastened to the housing 100 to prevent it from falling off. Specifically, the screw can pass through the housing 100 from the inner side of the housing 100 and be screwed into the first fixing portion 222 of the fixing member 220 to fasten the fixing member 220 to the housing 100.

[0034] In some embodiments, the control module and the indication module may be electrically connected via a wire. Specifically, the housing 100 may be provided with a through hole 130, one end of the wire is connected to the control module, and the other end passes through the through hole 130 and enters the second inner cavity 211 to connect to the indication module.

[0035] In some embodiments, the fixing member 220 may be formed as a part of the outer cover 210 , for example, the two may be integrally formed by injection molding.

[0036] In some embodiments, a sealing ring (not shown in the figure) may be provided between the protrusion 120 of the shell 100 and the inner wall of the outer cover 210, so that after the outer cover 210 is put on the outside of the protrusion 120, the gap between the outer cover 210 and the protrusion 120 can be sealed by the sealing ring to prevent water or water vapor from entering the interior of the shell 100 and the outer cover 210 and corroding the internal circuit.

[0037] When the indicator element includes a light source, the control module can be configured to make the light source emit a first color (e.g., green) when the controlled device is detected to be in a normal state, and emit a second color (e.g., red) when the controlled device is detected to be in an abnormal state. In this way, the user can determine whether the controlled device is in an abnormal state by observing the light signal emitted by the indicator module. When it is known that the controlled device is in an abnormal state, timely processing can be carried out to avoid damage to the controlled device.

[0038] When the indicator element includes a sound device, the control module can be configured to make the sound device silent when the controlled device is detected to be in a normal state, and to make the sound device emit an alarm sound when the controlled device is detected to be in an abnormal state. In this way, the user can judge whether the controlled device is in an abnormal state by whether the indicator module emits a sound. When the user hears the alarm sound emitted by the indicator module, the user can judge that the controlled device is in an abnormal state, so that timely processing can be carried out to avoid damage to the controlled device.

[0039] The controller of the embodiment of the utility model is provided with an indicating device 200 on the outer side of the shell 100. The indicating device 200 can send an indicating signal for indicating the operating status of the controlled device, so that the user can judge the operating status of the controlled device according to the indicating signal, and timely handle the controlled device when it is in an abnormal situation, so as to avoid damage to the controlled device; after the outer cover 210 of the indicating device 200 is fixed on the shell 100, the shell 100 can cover the opening of the outer cover 210, so that the control module and the indicating module are hidden in the shell 100 and the outer cover 210 respectively, so that only the shell 100 and the outer cover 210 can be seen from the outside, making the appearance of the controller more beautiful; the second circuit board can be fixed in the outer cover 210 by the fixing member 220 to prevent it from shaking; at the same time, the outer cover 210 and the shell 100 can be fastened by the fixing member 220, so that the two look like one body from the outside, ensuring the aesthetics.
