The fan draws air into the air guide cover from the air inlet, and the air flows along the upper air guide cover and the lower air guide cover. When it passes through the heat dissipation aluminum seat, it is heated up, and the Brownian motion intensifies, and then the heated air flows downward from the annular air inlet. Flowing into the above-mentioned filter space, part of the particles are adhered to the water droplets and taken away and fall into the water storage bucket.

The filtered air flows upward from the air outlet hood and along the air outlet, and passes through the cooling aluminum seat of the cooling fin assembly. The water vapor carried by the air passing through the water curtain is condensed into liquid water and returned to the water storage bucket.

The deflector makes the air more in contact with the cooling aluminum seat to ensure that the water vapor is fully condensed.

Because the water is filtered by the filter before spraying from the water spray column, the dirt in the water will not enter the water spray column and cause blockage to the water spray port, so the width of the water spray port can be designed to be smaller, which can increase the air and water flow. The contact area of the curtain can enhance the purification effect of the air.

The present invention not only utilizes the semiconducting refrigerating sheet to dehumidify the filtered air, but also utilizes the heat generated by the semiconducting refrigerating sheet to heat the unfiltered air, aggravating the Brownian motion of the air, so that when the air passes through the water curtain, the contact with the water curtain More, enhanced air purification effect.

Since the filter is only used to filter out particulate impurities in the water, the filter requirements for drinking water are much lower than that of drinking water, so the ceramic filter element has a larger pore size than the ceramic filter element of the drinking water filter, and the filtration flow rate is larger. The load of the water pump saves energy.

Every once in a while, the control circuit board controls the water pump to stop working, and at the same time, the first electromagnetic valve is closed and the second electromagnetic valve is opened. At this time, the filter performs the sewage discharge process.

Specifically, the water spray port of the filter is connected with the water inlet and outlet ports. When the water outlet port is out of water, the water flow pumped into the filter by the water pump is ejected from the water spray port to drive the water wheel to rotate, and finally drives the ceramic filter element assembly to rotate in the cylinder. , and between the cylinder body and the ceramic filter element assembly, bristles for removing dirt from the ceramic filter element are fixedly arranged, that is, brushing of the ceramic filter element assembly is realized while the filter is filtering water.

The water inlet and outlet interfaces are connected to the water pump, and the water outlet interface is connected to the water spray joint. When the water pump is in the open state, the piston on the upper part of the barrel moves upwards under the action of water pressure, and the spring connected to the piston contracts; when the second solenoid valve is opened At this time, the pressure in the waste water pipe is reduced. At this time, the spring stretches, the piston moves downward, and the water with dirt in the cylinder and outside the ceramic filter element flows into the waste water pipe through the water inlet and outlet interface, and is discharged into the waste water barrel.

When the present invention works, the control circuit board controls the water pump and the fan to work at the same time, the water pump pumps the water in the water storage barrel into the filter, and the filtered pure water is sprayed out from the water spray hole on the water spray column to form a filter space.

The fan draws air into the air guide cover from the air inlet, and the air flows along the upper air guide cover and the lower air guide cover. When it passes through the heat dissipation aluminum seat, it is heated up, and the Brownian motion intensifies, and then the heated air flows downward from the annular air inlet. Flowing into the above-mentioned filter space, part of the particles are adhered to the water droplets and taken away and fall into the water storage bucket.

The filtered air flows upward from the air outlet hood and along the air outlet, and passes through the cooling aluminum seat of the cooling fin assembly. The water vapor carried by the air passing through the water curtain is condensed into liquid water and returned to the water storage bucket.

The deflector makes the air more in contact with the cooling aluminum seat to ensure that the water vapor is fully condensed.

Because the water is filtered through the filter before spraying from the water spray column, the dirt in the water will not enter the water spray column and cause blockage to the water spray port, so the width of the water spray port can be designed to be smaller, and the water spray bar hole The density can be set higher, which can increase the contact area between the air and the water curtain, and enhance the purification effect of the air.

The present invention not only utilizes the semiconducting refrigerating sheet to dehumidify the filtered air, but also utilizes the heat generated by the semiconducting refrigerating sheet to heat the unfiltered air, aggravating the Brownian motion of the air, so that when the air passes through the water curtain, the contact with the water curtain More, enhanced air purification effect.

Since the filter is only used to filter out particulate impurities in the water, the filter requirements for drinking water are much lower than that of drinking water, so the ceramic filter element has a larger pore size than the ceramic filter element of the drinking water filter, and the filtration flow rate is larger. The load of the water pump saves energy.

Every once in a while, the control circuit board controls the water pump to stop working, and at the same time, the first electromagnetic valve is closed and the second electromagnetic valve is opened. At this time, the filter performs the sewage discharge process.

Specifically, the water spray port of the filter is connected with the water inlet and outlet ports. When the water outlet port is out of water, the water flow pumped into the filter by the water pump is ejected from the water spray port to drive the water wheel to rotate, and finally drives the ceramic filter element assembly to rotate in the cylinder. , and between the cylinder body and the ceramic filter element assembly, bristles for removing dirt from the ceramic filter element are fixedly arranged, that is, brushing of the ceramic filter element assembly is realized while the filter is filtering water.

The water inlet and outlet interfaces are connected to the water pump, and the water outlet interface is connected to the water spray joint. When the water pump is in the open state, the piston on the upper part of the barrel moves upwards under the action of water pressure, and the spring connected to the piston contracts; when the second solenoid valve is opened At this time, the pressure in the waste water pipe is reduced. At this time, the spring stretches, the piston moves downward, and the water with dirt in the cylinder and outside the ceramic filter element flows into the waste water pipe through the water inlet and outlet interface, and is discharged into the waste water bucket.

Example 3

This embodiment also has the following improvements on the basis of Embodiment 2. The raw material components of the ceramic filter element include: 80% diatomite, 6% calcium carbonate, 4% kaolin, 10% activated carbon, the above-mentioned The raw materials are crushed to 160-180 meshes and then mixed. After mixing evenly, water is added to make mud, and gypsum molds are used to make mud billets, which are sintered to form finished products. The ceramic filter element is in the shape of a circular tube, the thickness of the ceramic filter element is 5-15 mm, and the pore diameter of the micropores on the ceramic filter element is 0.4-0.8 μm.

Since the filter is only used to filter out particulate impurities in the water, the filter requirements for drinking water are much lower than that of drinking water, so the ceramic filter element has a larger pore size than the ceramic filter element of the drinking water filter, and the filtration flow rate is larger. The load of the water pump saves energy.
