The buzzer sounds when the fault indicator light is on, providing a more intuitive reminder to the operator of current overload or voltage abnormality, resulting in a better user experience.

[0011] In the aforementioned air compressor status display structure, a protrusion is formed on the inner side of the lower end of the top wall. The lower end of the top wall of the circuit board presses against the protrusion, and the two are fixedly connected by screws. A support portion is provided inside the housing to support the upper part of the circuit board upwards. This design offers advantages such as simple structure, convenient installation, and robustness.

[0012] In the above-mentioned air compressor status display structure, the limiting part is a support block formed on the inner wall of the cover part, and the upper end of the circuit board presses against the top wall of the support block.

[0013] In the aforementioned air compressor status display structure, the inner wall of the housing is also provided with a notch that matches the circuit board. There are two notches, which are respectively located on both sides of the support block, and the upper sides of the circuit board are respectively inserted into the two notches to enhance the positioning strength and stability of the circuit board.

[0014] Compared with existing technologies, the status display structure of this air compressor has the following advantages:

[0015] 1. By integrating multiple fault indicator lights into the housing and setting the housing at an angle, the operator can clearly see different abnormal states during the operation of the air compressor, so that the operator can make timely adjustments to ensure the normal operation of the air compressor.

[0016] 2. A buzzer is also installed on the circuit board, and the buzzer sounds when the current overload indicator light is on, so as to more intuitively remind the operator of the current overload and provide a better user experience. Attached Figure Description

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] like Figure 1 and Figure 2 As shown, the status display structure of this air compressor is set on the controller of the air compressor. The structure of the controller is basically the existing one. For details, please refer to the switch assembly described in the air compressor disclosed in the Chinese Patent Database (application number: 202420928788.1). The main modification of this application is to add a display structure for displaying the operating status of the air compressor on the controller.

[0024] Specifically

[0025] The controller includes a cover 1 and a main circuit board. In actual use, the cover 1 is set horizontally. The status display structure includes a circuit board 2 and multiple fault indicator lights 3 installed on the circuit board 2. The circuit board 2 is electrically connected to the main circuit board through wires.

[0026] Specifically

[0027] The fault indicator 3 includes at least one current overload indicator a and one voltage abnormality indicator b. The number of current overload indicator a is 1, and the number of voltage abnormality indicator b is 2, namely, a voltage overvoltage indicator and a voltage undervoltage indicator.

[0028] like Figures 2 to 4 As shown, the cover 1 is a one-piece structure, with one end being a protruding housing portion 1a, preferably elongated. The housing portion 1a is inclined, and the inner cavities of the housing portion 1a and the cover 1 are connected. The housing portion 1a includes a top wall 1b, and the circuit board 2 is inclinedly fixed inside the housing portion 1a, with the fault indicator light 3 located between the circuit board 2 and the top wall 1b. A vertically penetrating indicator hole 1c allows light emitted from the fault indicator light 3 to pass through the top wall 1b; the number of indicator holes 1c and the fault indicator light 3 are the same, and their positions are directly opposite each other.

[0029] During use, the operator can check whether the fault indicator light 3 is lit through the indicator hole 1c to determine the operating status of the air compressor.

[0030] By integrating multiple fault indicator lights 3 at the housing 1a and setting the housing at an angle, the operator can clearly see different abnormal states during the operation of the air compressor, so that the operator can make timely adjustments to ensure the normal operation of the air compressor.

[0031] Preferably, the end of the cover portion 1a near the middle of the cover 1 is positioned higher than the other end of the cover portion 1a, so that the cover as a whole becomes more compact and reduces space occupation; the tilt direction of the circuit board 2 is consistent with the tilt direction of the cover portion 1a.

[0032] To further explain, a buzzer 4 is also installed on the circuit board 2, and a sound outlet 1d is provided on the top wall 1b, which is directly opposite the buzzer 4. The buzzer 4 sounds when the fault indicator light 3 is lit, so as to more intuitively remind the operator of current overload or voltage abnormality, and the experience is better.

[0033] In this embodiment,

[0034] like Figure 3 and Figure 4 As shown, the positioning method of the circuit board 2 is as follows: a protrusion 1e is formed on the inner side of the lower end of the top wall 1b, the lower end of the top wall of the circuit board 2 presses against the protrusion 1e and the two are fixed together by screws 6, and a support part 1f is provided inside the cover part 1a for supporting the upper end of the circuit board 2 upward. The above design has the advantages of simple structure, convenient installation and reliable performance.

[0035] in,

[0036] The screw 6 is installed as follows: the protrusion 1e has a threaded hole, and the circuit board 2 has a corresponding through hole. The screw 6 rod passes through the through hole and is screwed into the threaded hole. The head of the screw 6 is pressed against the side of the circuit board 2 that is away from the protrusion 1e.

[0037] The limiting part is a support block formed on the inner wall of the cover part 1a, and the upper end of the circuit board 2 presses against the top wall 1b of the support block. To further explain, the inner wall of the cover part 1a is also provided with notches 1g that match the circuit board 2. There are two notches 1g, which are respectively provided on both sides of the support block, and the upper ends of the circuit board 2 are respectively inserted into the two notches 1g to enhance the positioning strength and stability of the circuit board 2.

[0038] In the actual product, a power indicator light 5 is also installed on the circuit board 2, and a clearance hole is provided through the cover 1 to face the power indicator light 5.

[0039] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
