The inner wall of the positioning cylinder provides a guide for the sliding of the positioning column, so that the filter screen cartridge is not easily offset when sliding in the water storage chamber, thereby improving the sliding stability of the filter screen cartridge in the water storage chamber.

[0010] By adopting the above technical solution, the pump body drives the water in the water tank to pass through the water inlet pipe and the water outlet pipe in turn and spray it from the nozzle onto the inner cavity of the filter screen cylinder.

The elastic force of the elastic member drives the positioning column to slide in the direction away from the positioning cylinder, and the cam wheel surface tends to press against the top surface of the filter screen cylinder. The cam has a large end and a small end. When the large end of the cam abuts against the top surface of the filter screen cylinder, the filter screen cylinder is driven away from the positioning cylinder. When the small end of the cam abuts against the filter screen cylinder, the filter screen cylinder approaches the positioning cylinder, thereby realizing the up and down sliding of the filter screen cylinder in the water storage chamber.

[0013] Optionally, the transmission assembly also includes an impeller 1, and the end of the cam rotating shaft passes through the outer wall of the water outlet pipe and is coaxially connected to the impeller 1, and the water in the water outlet pipe impacts the blades of the impeller 1 and drives the impeller 1 to rotate.

The impeller is coaxially connected to the cam rotating shaft, driving the cam to rotate on the surface of the water outlet pipe. There is no need for an external power device to drive the cam to rotate, which reduces energy loss and embodies the concept of energy saving.

[0015] Optionally, the cleaning device also includes a solenoid valve, a drainage channel is opened on the bottom wall of the water storage chamber, the drainage channel runs through the outer wall of the cleaning barrel, the solenoid valve is connected to the inner wall of the drainage channel, and the solenoid valve can control the on-off of the drainage channel and the water storage chamber.

[0019] Optionally, a heater is connected to the inner wall of the water storage chamber, and the heater can heat the air discharged from the intake air duct.

[0020] By adopting the above technical solution, the heater is connected to the inner wall of the water storage chamber and heats the air discharged from the intake air duct, so that the pins in the filter screen cylinder are fully in contact with the heated air and heat exchange is performed, thereby improving the drying efficiency of the pins.

[0021] Optionally, a drainage pipe is connected to the surface of the cleaning barrel, and the inner cavity of the drainage pipe is connected to the drainage channel.

The drainage pipe is connected to the drainage channel, and the water in the drainage channel is discharged through the drainage pipe, thereby realizing the discharge of water in the water storage chamber; when the air pump supplies air to the water storage chamber, the air is heated by the heater and fully contacts with the pins in the filter screen cylinder and performs heat exchange, thereby accelerating the drying efficiency of the pins in the filter screen cylinder. At the same time, the air pressure in the water storage chamber increases, and the air in the water storage chamber enters the drainage channel. The buoyancy of the float caused by the water disappears, and the float slides toward the drainage pipe.

[0024] By adopting the above technical solution, when water or air in the water storage chamber enters the drainage channel, the water or air impacts the second blade of the impeller, driving the second impeller to rotate, and the synchronous belt is tightened to connect the two synchronous wheels, so that the cam keeps rotating when there is no water flowing out of the water outlet pipe. The pins in the filter screen cylinder are fully in contact with the air and heat exchange is carried out, thereby improving the drying efficiency of the pins. At the same time, there is no need for an external power device to keep the cam in a rotating state, thereby embodying the concept of energy saving.

The inner cavity of the filter screen cartridge 62 is connected to the water storage chamber 611 through the sieve holes on the filter screen cartridge 62. The inner cavity of the filter screen cartridge 62 is used to store pins. When the filter screen cartridge 62 slides up and down in the water storage chamber 611, the water in the water storage chamber 611 is driven to impact the pins in the filter screen cartridge 62 through the sieve holes, so that the water fully contacts and cleans the surface of the pins, thereby cleaning the electroplating liquid residue on the surface of the pins, making the surface of the pins less susceptible to corrosion, thereby extending the service life of the board-to-board connector with ultra-small spacing.
