[0027] The present invention is further described below in conjunction with specific embodiments:

[0028] A control box with a heat dissipation structure, such as Figure 1-5 As shown, it includes a box body 1, and an installation cavity 14 is formed in the box body 1, and the installation cavity 14 is used to install a control component for controlling the operation of the cleaning machine; an exhaust port 2 is provided at the bottom of the box body 1, and an exhaust component 6 is installed on the exhaust port 2; a plurality of air inlets are provided above the box body 1, and the exhaust component 6 is used to suck external air into the box body 1 from the air inlets, and pass through the control component located in the installation cavity 14, and then discharge it from the exhaust port 2.

[0029] refer to Figure 1 , 5 As shown, the box body 1 is square. In this embodiment, the box body 1 includes a basket-shaped front shell 11 and a cover fixed on the rear side of the front shell 11. Figure 5 The front shell 11 is formed with the installation cavity 14, and a snap structure 12 is provided on the outer edge of the front shell 11. The cover can be snapped into the front shell 11 through the snap structure 12 to realize the assembly of the box body 1. The control component is used to be installed in the installation cavity 14 of the front shell 11, which is specifically a circuit board. The circuit board is connected with wires, and the wires pass downward through the wire holes 13 located at the bottom of the box body 1 to connect to the power supply of the cleaning machine; the circuit board is integrated with a control circuit, and a plurality of buttons are arranged on the circuit board. A plurality of button components 4 are provided on the box body 1. The user can drive the buttons on the circuit board by pressing the button components 4 on the box body 1 to control the control circuit in the circuit board to realize the control of the cleaning machine.

[0030] The exhaust port 2 is arranged on the bottom of the box body 1. The exhaust component is specifically a fan fixed on the bottom of the box body 1. The fan is connected to the power supply in the cleaning machine. When the control box in this patent is powered, the fan is powered accordingly. The air inlet is arranged above the box body 1. In this embodiment, the air inlet includes a positive air inlet 31 arranged on the outer edge of the button component 4, such as Figure 1 , 2 As shown, the positive air inlet 31 is specifically a plurality of square openings arranged around the outer edge of the button assembly 4. When the exhaust assembly is working, the exhaust assembly exhausts the outside air from the positive air inlet 31 into the box body 1, and then discharges it outward from the exhaust port 2, and passes through the control assembly installed at the button assembly 4 to achieve heat dissipation and cooling. By placing the positive air inlet 31 opposite to the front of the control assembly, the heat dissipation effect on the control assembly is increased.

[0031] Furthermore, the button assembly 4 in the present invention includes a button port 41, a button block 42 and a button connecting strip 43, such as Figure 2 ,4 As shown, the button port 41 is opened on the front of the box body 1, and the button port 41 is square in shape as a whole. The button block 42 is round in shape as a whole and is placed in the button port 41. The button port 41 and the button block 42 are connected by a button connecting strip 43. The button connecting strip 43 is generally made of plastic material. The button block 42 can be pressed to move the button block 42, and the button block 42 can be moved to drive the buttons on the control component in the box body 1. At the same time, a through hole is formed between the button connecting strip 43 and the button port 41, which can be used to further dissipate heat of the control component.

[0032] Furthermore, a plurality of side air inlets 32 are provided on the side walls of the box body 1, and a waterproof structure is provided outside the side air inlets 32 to prevent liquid from entering the box body 1 through the side air inlets 32. Figure 2 , 3 As shown, the waterproof structure described in this patent includes a plurality of grooves 51 opened on the two side walls of the box body 1. The grooves 51 are square and are opened on the side walls of the box body 1 in sequence. The side air inlet 32 ​​is opened on the upper inner end surface of the groove 51. Figure 3 As shown, since the side air inlet 32 ​​is arranged upward, the side air inlet 32 ​​will be blocked by the raised structure on one side of the groove 51, thereby achieving waterproofing; at the same time, the side air inlet 32 ​​is connected to the outside world, and further heat dissipation can be carried out through the side air inlet 32. Generally, hot air will move upward, and cold air will move downward. Setting the side air inlet 32 ​​upward will help to discharge the hot air as soon as possible to facilitate heat dissipation.

[0033] In addition, since the side air inlet 32 ​​in the present patent is arranged higher than the control component, when the exhaust component 6 works to suck air, an upward and downward flowing gas will be formed, and the gas will flow through the control component and fully contact it, thereby better dissipating the heat of the control component.

[0034] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
