In this way, the purpose of conveniently carrying and moving the air purifier 100 can be achieved, and at the same time, it can also save manpower and material resources during the moving process.

The above filter assembly 2 is arranged on the base 1 .

As shown in FIG. 2 , in a preferred embodiment, the filter assembly 2 includes a high-efficiency filter 23 , a medium-efficiency filter 24 and a primary-efficiency filter 25 , which are sheathed in sequence from the inside to the outside. Among them, the high-efficiency filter 23 is mainly used to trap particles below 0.5um (micrometer), dust, various suspended solids, and harmful gases.

In a specific embodiment, the high-efficiency filter 23 can be a high-efficiency filter net, which can use ultra-fine glass fiber paper as the filter material, and use materials such as offset paper or aluminum film as the partition board, and then use aluminum alloy glue to glue it on Just on the wooden frame.

The medium-efficiency filter 24 is mainly used to trap 1-55 μm (micron) particle dust and various suspended matter. The medium-efficiency filter 24 can be a medium-efficiency filter, which can be made of special non-woven fabric or glass fiber, so that the medium-efficiency filter can be cleaned repeatedly.

The primary filter 25 is mainly used to filter dust particles above 55 μm (micrometer). It can be non-woven fabric, nylon mesh, iron mesh or aluminum mesh, etc.

It can be seen that through the arrangement of the primary filter 25 , the medium filter 24 and the high efficiency filter 23 , the external air can be filtered layer by layer, thereby achieving the purpose of cleaning the external air.

It can be seen that the arrangement of the above-mentioned air inlets can facilitate the external air to enter the inside of the filter assembly 2 through the above-mentioned air inlets. In this way, under the above-mentioned situation that the wind can be taken in from all sides, the bottom case 1 can also be taken in by the wind. That is, on the basis of the original volume of air entering the filter assembly 2 per unit time, the volume of air entering the filter assembly 2 per unit time is further increased. It can be seen that, if the bottom case 1 is also designed as the air inlet surface 21, the output ratio of clean air is greatly improved, thereby satisfying the needs of users well.

Since the function of the above-mentioned bottom filter 26 is the same as that of the above-mentioned high-efficiency filter 23, in order to avoid redundant description, it will not be described in detail here.

In one embodiment, the high-efficiency filter 23 can be constructed as a stretchable and foldable filter net by a plurality of blades sequentially connected to each other. It can be seen that adopting a foldable and retractable filter screen greatly increases the filtering area of the high-efficiency filter 23, thereby increasing the dust collection and dust holding capacity. Further, the filtering performance of the high efficiency filter 23 is greatly improved.

As shown in Figures 2 and 3, in a preferred embodiment, the air cleaner 100 also includes a filter positioning frame 4, and an annular groove is configured on the end face of the filter positioning frame 4 facing the bottom shell 1 41. Specifically, the open end of the annular groove 41 faces the bottom case 1 .

In a preferred embodiment, the upper ends of the primary filter 25 , the medium filter 24 and the high efficiency filter 23 are all embedded in the annular installation groove 41 . It can be seen that the setting of the filter positioning frame 4 can play the role of fixing the above-mentioned primary effect filter 25, medium effect filter 24 and high efficiency filter 23, avoiding the effect of the primary effect filter 25, medium effect filter 24 and high efficiency filter. The upper end of the high-efficiency filter 23 is deformed horizontally or vertically in the same horizontal plane.

As shown in FIG. 4 , in a preferred embodiment, the fan assembly 3 includes a first air intake grill 421 arranged on the upper end surface 42 of the filter positioning frame 4 , and on the first air intake grill 421 A plurality of through holes 422 are configured, and each through hole 422 communicates with the air inlet channel 231 . Specifically, by making each through hole 422 communicate with the air inlet channel 231 , the clean air purified by the filter assembly 2 can be transported into the fan assembly 3 through the air inlet channel 231 . Thus, preparations are made for delivering the clean air to the outside of the air cleaner 100 .

In a preferred embodiment, the fan assembly 3 also includes an outer cover 5 arranged on the first air inlet grille 421, and a centrifugal fan 32 is arranged inside the outer cover 5 and above the air inlet passage 231, and the centrifugal fan 32 The outer side of the fan 32 is provided with a plurality of centrifugal impellers 33 staggered from each other. The outer cover 5 can be arranged on the first air inlet grill 421 through a detachable connection, and its outer dimension is exactly the same as that of the primary filter 25 .

The centrifugal fan 32 is arranged above the air inlet channel 231, and all the clean air filtered by the filter assembly 2 can be effectively delivered to the outside of the air cleaner 100, so as to achieve the purpose of purifying the indoor air.

The above-mentioned centrifugal impeller 33 can be fixed on the outside of the centrifugal fan 32 by welding, and mainly plays the role of transporting the clean air to the outside.

In the embodiment of the present application, the centrifugal fan 32 has the advantages of high wind pressure and strong suction, so it can deliver a larger volume of clean air per unit time, thereby greatly improving the delivery efficiency of clean air.

As shown in Figure 3 and Figure 4, in a preferred embodiment, the fan assembly 3 also includes an air outlet net 52 arranged at the upper port 51 of the outer cover 5, and the above-mentioned air outlet is configured on the air outlet net 52 521. However, the specific number of the air outlets 521 can be adjusted according to the actual needs of users. It can be seen that the setting of the air outlet net 52 can make the clean air evenly delivered to the outside of the air purifier 100, avoiding that the clean air is only blown out in one place, causing a certain place with a strong wind force and reducing the user's air flow during use. The disadvantages of comfort.

As shown in Figure 4, in a preferred embodiment, an annular plate 6 is provided on the first inlet grille 421, and the annular plate 6 wraps the centrifugal fan 32 and each centrifugal impeller 33 respectively. The wind net 52 and the first air inlet grille 421 are configured as an air outlet channel 7 , and the air outlet channel 7 communicates with the air inlet channel 231 . In this way, the external air can be converted into clean air after being filtered by the filter assembly 2 , and enter into the fan assembly 3 from the air inlet channel 231 . Then, under the joint action of the centrifugal fan 32 and the centrifugal impeller 33, the clean air will be transported to the outside along the air outlet channel 7 through the air outlet 521, so as to achieve the purpose of purifying the indoor air.

In the embodiment of the present application, a control panel 200 is installed on the area where the outer cover 5 and the primary filter 25 are connected. The setting of the control panel 200 can set corresponding functions such as the wind speed of the air outlet, the volume of the clean air delivered, and whether to continuously output the clean air according to the actual needs of the user. It can be seen that the setting of the control panel 200 greatly improves the intelligence of the air purifier 100 and at the same time brings convenience to the user.

To sum up, the air purifier 100 has the advantages of high purification efficiency, good purification effect, simple structure, easy installation and disassembly, flexible movement, and more clean air output per unit time and unit area.

While the invention has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for parts thereof without departing from the scope of the invention. In particular, as long as there is no structural conflict, the technical features mentioned in the various embodiments can be combined in any manner.
