[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] like Figures 1-2 As shown, this utility model provides an air duct structure for handling dust at the switch push button of an angle grinder, including a dust inlet 2 connected to the inner cavity of the angle grinder housing 1, an air guide channel 3 located in the inner cavity of the angle grinder housing 1, and a dust outlet 4 communicating with the inner cavity of the angle grinder housing 1. The dust inlet 2 is located on the fastening surface between the push button 5 and the housing 1, and is located on one end of the push button 5. The dust outlet 4 is located at the heat dissipation exhaust of the angle grinder. The heat dissipation component provided in the inner cavity of the housing 1 is used to discharge dust through the cooperation of the air guide channel 3 and the dust outlet 4.

[0026] The heat dissipation component includes a rotating shaft 8 connected to the output end of the motor 7 inside the housing 1 and a fan blade 9 connected to the rotating shaft 8. The housing 1 is composed of a flow guiding component consisting of the motor 7, the rotating shaft 8, and the fan blade 9. Since the heat dissipation component plays a key role in the normal operation of the angle grinder, this technology is a structure already present in conventional angle grinders and will not be elaborated on in this article. It should be noted that when the motor 7 inside the housing 1 drives the rotating shaft 8 to rotate, the rotating shaft 8 can drive the fan blade 9 to rotate synchronously. As the fan blade 9 rotates, it will form an airflow in the housing 1. The airflow flows in from a specific area of ​​the housing 1, passes through the motor 7, and is discharged through the dust outlet 4 (i.e., the air outlet) provided on the head shell 6. In this process, the cooperation of the rotating shaft 8 and the fan blade 9 can guide the airflow to flow evenly and efficiently, which not only ensures effective heat dissipation for the motor 7 and other internal components and ensures the stable operation of the angle grinder for a long time, but also some of the airflow can assist the air duct structure to help the dust to be discharged.

[0027] As further, the air duct structure for processing dust at the switch push button of the angle grinder further comprises a power supply assembly 12 arranged at the end of the casing 1 away from the push button 5, wherein the power supply assembly 12 is used for supplying power to the motor 7 to ensure that the motor 7 drives the fan blade 9 to rotate via the rotating shaft 8, so as to accelerate the flow speed of the dust in the air guide channel 3 when the air guide assembly rotates, and facilitate the rapid discharge of the dust.

[0028] In combination Figure 2 As further shown, the air guide channel 3 is arranged from the dust inlet 2 to the dust outlet 4 (3-1, 3-2, 3-3, 3-4), and it is worth noting that the red arrows in the figure are used to identify the channels (3-1, 3-2, 3-3, 3-4), mainly indicating a flow direction of the dust after entering the inner cavity of the casing 1.

[0029] As further, one end of the casing 1 is connected with a head shell 6, and the dust outlet 4 is arranged on the head shell 6. The inner wall of the dust outlet 4 is provided with a smooth coating. The design of arranging the smooth coating on the dust outlet 4 can effectively reduce the friction of the dust flow, improve the discharge efficiency of the dust, and further accelerate the flow speed of the dust in the air duct, thereby enhancing the dust discharge effect.

[0030] In combination Figure 2 As further shown, the dust inlet 2 is located at the front end side of the push button 5, and the push button 5 has a first working position and a second working position. When the push button 5 is in the first working position, the front bottom of the push button 5 is arranged on the buckling surface. When the push button 5 is in the second working position, the front bottom of the push button 5 is arranged in the dust inlet 2, and an interval for the dust to enter is arranged between the front end of the push button 5 and the dust inlet 2. The existence of the interval makes the dust generated by the operation of the angle grinder enter the dust inlet 2 through the interval when the push button 5 pushes to open the angle grinder, so as to facilitate the dust to flow outwards along the air guide channel 3 after entering the inner cavity of the casing 1.

[0031] In combination Figure 2 As further shown, the dust inlet 2 is located at the front end side of the push button 5, and the push button 5 has a first working position and a second working position. When the push button 5 is in the first working position, the front bottom of the push button 5 is arranged on the buckling surface. When the push button 5 is in the second working position, the front bottom of the push button 5 is arranged in the dust inlet 2, and an interval for the dust to enter is arranged between the front end of the push button 5 and the dust inlet 2. The existence of the interval makes the dust generated by the operation of the angle grinder enter the dust inlet 2 through the interval when the push button 5 pushes to open the angle grinder, so as to facilitate the dust to flow outwards along the air guide channel 3 after entering the inner cavity of the casing 1.

[0032] Further, when the user pushes the push button 5, the push button 5 can drive the switch sliding plate 10 to displace, and then the switch sliding plate 10 can trigger the switch 11 after displacement, thereby starting the angle grinder. The inner wall of the dust inlet 2 is arranged to be inclined, which can ensure the stability of the push button 5 when pushing to open the angle grinder.

[0033] The working principle and use process of the utility model: the utility model discloses the push button 5 and the buckling area of the shell 1 are opened and worn, and then the operator can manually push the push button 5 and drive the switch sliding plate 10 to produce displacement when operating the angle grinder, the switch sliding plate 10 can trigger the switch 11 after displacement, and then the angle grinder is started, at the same time, the motor 7 can drive the fan blade 9 to rotate, the dust entering from the gap of the push button 5 buckling surface can enter the inner cavity of the shell 1 during the rotation of the fan blade 9, and is blown out from the dust outlet 4 along the air guide channel 3, therefore, the utility model discloses the ingenious design of blowing dust by using the air duct, and the problem that the push button 5 position of the angle grinder is accumulated dust and affects the flexibility of the whole machine and the push button 5 blockage leads to failure is solved, the use experience of the consumer is improved, and the service life of the machine is prolonged.
