Description

Technical Field

[0001] This utility model relates to the field of high-voltage AC brushless angle grinder technology, specifically to an angle grinder with an electronic side switch. Background Technology

[0002] An angle grinder is a handheld power tool widely used for grinding, cutting, and polishing metals and wood. It is usually driven by a motor and uses a grinding wheel or cutting disc mounted on the motor shaft to perform surface treatments on various materials. Due to its ease of operation, high efficiency, and wide applicability, the angle grinder has become an indispensable tool in industrial and household maintenance. The side switch of a traditional angle grinder is a mechanical lever type, which is used on AC brushless angle grinders. It has obvious disadvantages: first, the reliability of the lever type or mechanical structure is poor; second, the service life is short; and third, it is easy to fall off during startup and disconnect the power supply.

[0003] The existing technology has the following problems:

[0004] Pull-rod or side switches are used in AC brushless tools. Press-button switches on the controller are prone to failure. Customers of AC brushless angle grinders require warranty periods, which pull-rod type angle grinders cannot provide. Traditional pull-rod switches are bulky and inconvenient to hold. Utility Model Content

[0005] This invention provides an angle grinder with an electronic side switch to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] An angle grinder with an electronic side switch includes an angle grinder body. A start button is provided on the right side of the front surface of the outer surface of the angle grinder body, and a working indicator light is provided on the rear side of the outer surface of the start button. A stop button is provided on the left side of the front surface of the outer surface of the angle grinder body, and a stop indicator light is provided on the rear side of the outer surface of the stop button.

[0008] A further improvement of this utility model is that both the start button and the stop button are momentary electronic switches.

[0009] A further improvement of this utility model is that the working indicator light is a green indicator light.

[0010] A further improvement of this utility model is that the stop indicator light is a yellow indicator light.

[0011] A further improvement of this utility model is that a timing device is provided around the stop indicator light, and the stop indicator light changes from yellow to red when the warranty expires.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0013] 1. This utility model provides an angle grinder with an electronic side switch. The mechanical switch is a pull rod type, which generally has a lifespan of 50,000 cycles. The lifespan can be increased to more than 250,000 cycles by using a momentary electronic switch.

[0014] 2. This utility model provides an angle grinder with an electronic side switch. It adopts a momentary electronic switch and has a timing function around it. The timing LED is provided next to the button, which makes it clear to the customer at a glance. There is no dispute when the product's warranty period expires.

[0015] 3. This utility model provides an angle grinder with an electronic side switch. It adopts a momentary electronic switch, which is small in size, ergonomic, and increases the comfort of the user. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the angle grinder of this utility model.

[0017] In the diagram: 1. Angle grinder body; 2. Start button; 21. Working indicator light; 3. Stop button; 31. Stop indicator light. Detailed Implementation

[0018] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0019] like Figure 1 As shown, this utility model provides an angle grinder with an electronic side switch, including an angle grinder body 1. A start button 2 is provided on the right side of the front surface of the angle grinder body 1. A working timer indicator light 21 is provided on the rear side of the outer surface of the start button 2. A stop button 3 is provided on the left side of the front surface of the angle grinder body 1. A stop indicator light 31 is provided on the rear side of the outer surface of the stop button 3. Both the start button 2 and the stop button 3 are momentary electronic switches. The working timer indicator light 21 is a green indicator light, and the stop indicator light 31 is a yellow indicator light. A timing device is provided around the stop indicator light 31. When the stop indicator light 31 changes from yellow to red, it means the warranty has expired.

[0020] The working principle of this type of angle grinder with an electronic side switch will be explained in detail below.

[0021] like Figure 1As shown, when using the angle grinder, press the start button 2 twice to start the grinder. The green light on the work timer indicator 21 will illuminate, and the yellow light on the stop indicator 31 will turn off. Press the stop button 3 once to turn off the green light on the work timer indicator 21 and illuminate the yellow light on the stop indicator 31, thus stopping the grinder. When the stop indicator 31 changes from yellow to red, it indicates that the warranty has expired. This is clear to the customer and ensures that there are no disputes about the expiration of the product's warranty period.

[0022] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
