Description

A water filter and air purification device suitable for household use

technical field

The invention relates to a water filter and air purification device suitable for household use, which belongs to the category of air purification equipment.

Background technique

With the rapid development of large-scale industrial production, environmental protection problems are becoming more and more serious, more and more hazy weather, and frequent P2.5 storms in various places are specific manifestations of increasingly harsh environmental conditions. processing becomes very necessary and important. In the prior art, the air dust removal and purification process basically adopts the filtering method. The principle is: the air is

Driven by the fan, it passes through the filter material, and the solid particles and adsorbable substances (or soluble substances) in the air are adhered by the filter material and stay in the filter material, while the purified air passes through.

According to the dry and wet state of the filter material, the filtration methods of air dust removal and purification can also be divided into dry filtration and wet filtration. The ideal filter material should be: 1. High gas-solid separation efficiency; 2. Small pressure loss; 3. Long cleaning life; 4. Easy to clean; 5. No secondary pollution; 6. High cost performance.

Comparing various dry filtration and wet filtration filter materials, the water filtration in wet filtration uses water as the filter material, which is the most ideal in principle. However, most of the existing water filtration devices are industrial application products, including complex pumping systems and water-air separation systems, which consume a lot of power and are not suitable for home and office use. Obviously, there is a need for further improvement of the existing technology.

Contents of the invention

The purpose of the present invention is to provide a water filtration and air purification device suitable for household use, so as to overcome the problems in the prior art.

A water filtration and air purification device suitable for household use according to the present invention includes a guide fan, an exhaust fan and a water tank, and is characterized in that the water tank includes a lower box and an upper box, and the lower box and the upper box The body is detachably sealed and connected, the lower box contains liquid water for filtering, the air guide fan and the exhaust fan are respectively arranged on the upper positions of the two opposite sides of the upper box, and also include metal materials The air guide pipe is made, the air guide pipe is in the shape of a tapered tube, the large end of the upper end is connected with the exhaust end of the air guide fan, the small end and the small end are inserted into the liquid water in the lower box, and the air intake end of the exhaust fan is It communicates with the upper box space.

As a further improvement, an inverted conical isolation plate is interposed between the lower box space and the upper box space, and the lower edge of the inverted conical isolation plate is connected to the position below the periphery of the upper box, leaving There is a slot through the water tank, and a converging air guide hole is opened at the top of the cone of the inverted cone-shaped isolation plate.

Preferably, the converging air guide hole is located at the lower position of the tapered tubular air duct.

As a further preference, a water injection hole with a cover is opened on the upper box body, so that the upper box body and the lower box body do not need to be disassembled, and the liquid water can be replenished only by opening the cover and passing through the water injection hole.

This water filtering and air purification device suitable for household use of the present invention, when in use, the air introduced by the air guide fan is guided and compressed by the cone-shaped air guide pipe and injected into the liquid water, and the dust in the air remains in the liquid water after being filtered by water. The air bubbles out and enters the space defined by the liquid water and the inverted cone-shaped partition. Under the action of the exhaust fan, the space defined by the inverted-cone partition and the upper box forms a negative pressure. The air in the space defined by the inverted cone partition enters the space defined by the inverted cone partition and the upper box through the convergent air guide hole, and finally is discharged into the home space through the exhaust fan. After a period of use, the liquid in the lower box If the water is polluted, just take off the upper box body, pour out the sewage in the lower box body, and replace it with new liquid water. In the process of water filtration, since the liquid water is stirred by the incoming air, it will inevitably evaporate to form water vapor. When the space defined by the isolation plate and the upper box is densely compressed due to the effect of the inverted cone-shaped isolation plate, the result of intensive compression is that the chance of water vapor colliding with each other increases, and it is easier to gather to form larger individuals and become water droplets, especially Under the preferred scheme, the air and water vapor derived from the convergent air guide hole are directly blown to the metal material to make a conical air guide pipe, and the inside of the tapered tubular air guide pipe is continuously passed by the air flow under the action of the air guide fan. For this reason, its temperature is relatively low. After the water vapor exchanges with it, the temperature is further reduced, and more water vapor is condensed into water, which lands on the inverted cone-shaped separation plate, and flows back to the lower box through the slot of the water tank. Obviously, the present invention Can reduce the humidity of exhaust fan discharge air preferably, this water filter air purification device of the present invention, because its structure is simple, manufacturing cost is low and use cost is all lower, is suitable for this reason for the popularization of popular household use, sums up Described, obviously the object of the present invention is achieved.
