Description

Technical Field

[0001] The utility model belongs to the field of electric tools and relates to a heat dissipation structure of a marble machine. Background Art

[0002] Marble machine refers to a stone cutting machine, which can be used to cut stone, tile, wood, metal, etc. Different materials require corresponding cutting blades.

[0003] According to the material of the marble machine cutting material, a high-speed motor is required to achieve a safe and effective cutting effect. Whether it is a brushed motor or a brushless motor, it is very easy to overheat under high-power operation in a small space, and the brushed motor is more serious. The internal structure of existing marble machine products is often very compact, and many components, especially motors and circuits, are arranged together without a reasonable arrangement. This makes it difficult to dissipate the internal heat in time during operation, and even if active heat dissipation such as air cooling is applied, the airflow cannot effectively remove the heat due to the disordered gaps in the internal structure. Utility Model Content

[0007] Furthermore, the motor assembly is disposed in the second chamber, and the motor assembly includes a motor and a fan blade, and the fan blade is disposed at the air outlet. When the motor is working, it drives the fan blade to rotate to generate suction in the second chamber.

[0008] Furthermore, the air inlet is arranged at an end of the first chamber away from the connecting port, and the air outlet is arranged at an end of the second chamber away from the connecting port.

[0009] Furthermore, the circuit component is disposed in the first chamber.

[0022] The utility model provides a heat dissipation structure of a marble machine, referring to Figure 1 and Figure 2 , including a casing 1 constituting the exterior of the marble machine, and a motor component 4 and a circuit component 3 arranged inside the casing 1. The motor component 4 and the circuit component 3 are both heat-generating components, and high-efficiency heat dissipation is achieved through the heat dissipation structure.

[0023] Specifically, refer to Figure 3 A partition 2 is provided inside the casing 1, and the partition 2 divides the internal space of the casing 1 into two parts, including a first chamber 11 and a second chamber 12, wherein a connecting port 13 is provided on one side of the partition 2 near the inner wall of the casing 1, connecting the first chamber 11 and the second chamber 12 to form a U-shaped cavity structure.

[0024] The casing 1 is provided with an air inlet 111, and the air inlet 111 is connected to the first chamber 11. The end of the second chamber 12 away from the connecting port 13 is set as an air outlet 121. The motor component 4 is located in the second chamber 12, including a motor and a fan blade 41 arranged at the front end of the motor. The fan blade 41 is located at the position of the air outlet 121. When the motor is working, it will drive the fan blade 41 to rotate, generate suction in the second chamber 12, and then form an airflow direction in the casing 1, that is, the outside air enters the first chamber 11 from the air inlet 111, flows through the second chamber 12 through the connecting port 13, and finally flows back to the outside from the fan blade 41, so that the active heat dissipation effect is achieved for the circuit component 3 and the motor component 4 in the casing 1 through this airflow.

[0025] The air inlet 111 is arranged at a side away from the connecting port 13, and the air outlet 121 and the fan blade 41 are also arranged at an end of the motor away from the connecting port 13, so that the airflow passing through the housing 1 also presents a U-shaped direction.

The circuit component 3 can be fixed on the partition 2. The circuit component 3 includes a circuit board, and the circuit board can be provided with heat-conducting fins 31. The direction of the heat-conducting fins 31 is set along the airflow direction, so that the airflow can fully pass through the gaps between the fins, increase the contact area, and enhance the heat dissipation effect.

[0027] Furthermore, the cutter disc of the marble machine is arranged on one side of the housing 1 close to the air outlet 121, and the airflow blown out from the air outlet 121 directly hits the cutter disc to blow away the cutting chips and cool the cutter disc to a certain extent.
