[0041] Example 1

[0042] This embodiment provides an air purification device. In one embodiment, Figures 1 to 4 As shown, the air purification device includes a base 1, an air inlet panel 2, a filter 7, a top cover 3, a sealing partition 4, and a fan, wherein the fan is not shown in the figure.

[0043] Among them, the air inlet panel 2 is arranged on the base 1, and the air inlet panel 2 includes an air inlet part 21, and the air inlet part 21 is provided with an air inlet hole 22; the filter 7 is arranged on the inner side of the air inlet panel 2; the top cover 3 is arranged above the air inlet panel 2 in a liftable manner, and when the top cover 3 rises, an air outlet is formed between the top cover 3 and the air inlet panel 2; the sealing baffle 4 is arranged on one side of the air inlet part 21 in a liftable manner, and the sealing baffle 4 has an initial position and a working position. When the sealing baffle 4 is in the initial position, the sealing baffle 4 blocks the air from passing through the air inlet hole 22 and entering the interior of the air purification device.

[0044] The air purification device provided in this embodiment is provided with a sealing baffle 4 on one side of the air inlet part 21. When the air purification device is not working, the sealing baffle 4 is located on one side of the air inlet part 21, and the top cover 3 is provided above the air inlet panel 2. The sealing baffle 4 blocks the air from entering the air purification device through the air inlet hole 22 on the air inlet part 21. The top cover 3 can also block the air from entering, thereby preventing the filter 7 from getting moldy. When the air purification device is working, the sealing baffle 4 is switched to the working position, and the top cover 3 rises. Under the action of the fan, the air enters the air purification device through the air inlet hole 22, and is blown out from the air outlet after being filtered by the filter 7.

[0045] On the basis of the above-mentioned embodiments, in a preferred embodiment, the sealing baffle 4 is fixedly connected to the top cover 3, and when the sealing baffle 4 is in the initial position, the top cover 3 is covered on the air inlet panel 2. This arrangement allows the top cover 3 to rise when the sealing baffle 4 rises, and to fall when the sealing baffle 4 falls. When the sealing baffle 4 returns to its initial position, the top cover 3 is also covered on the air inlet panel 2, ensuring that air does not enter the interior of the air purification device. The structure is simple and compact, and easy to operate. In an alternative embodiment, the sealing baffle 4 and the top cover 3 are not connected. When the air purification device is working, the sealing baffle 4 and the top cover 3 are raised respectively. When the air purification device is not working, the sealing baffle 4 and the top cover 3 are lowered respectively, so that the sealing baffle 4 falls to the initial position, and the top cover 3 falls to cover the air inlet panel 2.

[0046] Based on the above embodiment, in one embodiment, the sealing baffle 4 is connected to the top cover 3 via a plurality of top rods 5. This arrangement allows the top rods 5 to occupy less space when the top cover 3 rises with the sealing baffle 4, and the gaps between the top rods 5 are larger, which does not affect the air outlet. In an alternative embodiment, the sealing baffle 4 and the top cover 3 may be connected via a plate-like member.

[0047] On the basis of the above-mentioned embodiment, in a preferred embodiment, the air inlet panel 2 includes a main body, and the main body is located on the upper side of the air inlet portion 21, such as Figure 3 and Figure 4 As shown, the main body includes an inner wall 23 and an outer wall 24, and an annular cavity 25 is formed between the inner wall 23 and the outer wall 24. When the sealing baffle 4 is in the working position, the sealing baffle 4 is located in the annular cavity 25, and when the sealing baffle 4 is in the initial position, the push rod 5 is located in the annular cavity 25. This arrangement allows the sealing baffle 4 to be hidden in the annular cavity 25 when the air purification device is working, and the push rod 5 to be hidden in the annular cavity 25 when the air purification device is not working, which is more beautiful in appearance. In an alternative embodiment, the main body includes only one layer of wall, the main body and the air inlet 21 are an integrated structure, and the sealing baffle 4 and the push rod 5 are simultaneously arranged on the outside or inside of the air inlet panel 2. When the sealing baffle 4 is not connected to the push rod 5, one of the sealing baffle 4 and the push rod 5 can be arranged on the outside of the air inlet panel 2, and the other can be arranged on the inside of the air inlet panel 2.

[0048] On the basis of the above embodiment, in one embodiment, the air inlet portion 21 is the lower half of the air inlet panel 2. This arrangement allows the sealing baffle 4 to be supported on the base 1 when the sealing baffle 4 is in the initial position, and the structure is relatively compact. In an alternative embodiment, the air inlet portion 21 may be the middle part of the air inlet panel 2. The working position of the sealing baffle 4 may be a lowered position, which is lowered to expose all the air inlet holes 22.

[0049] On the basis of the above embodiment, in a preferred embodiment, when the sealing baffle 4 is in the initial position, the sealing baffle 4 is located outside the air inlet 21. This arrangement can effectively block air from entering the interior of the air purification device without occupying the internal space of the air purification device. In an alternative embodiment, the sealing baffle 4 can be arranged on the inner side of the air inlet 21.

[0050] On the basis of the above embodiment, in a preferred embodiment, the air purification device further comprises a driving device for driving the sealing baffle 4 to move up and down. The driving device is used to drive the sealing baffle 4 to move up and down, which is convenient for manual control operation. In an alternative embodiment, the driving device may not be provided, and the position of the sealing baffle 4 may be adjusted manually.

[0051] In one embodiment, the driving device includes an electric push rod 6, which is arranged on the base 1, and the end of the electric push rod 6 is connected to the sealing partition 4. The structure of the driving device is relatively simple. In an alternative embodiment, the driving device can be a gear rack mechanism, and the rack is connected to the sealing partition 4 to drive the sealing partition 4 to move up and down.

[0052] like Figure 1 As shown, two electric push rods 6 are provided and distributed at the diagonal positions of the sealing partition 4. This arrangement can stably support the sealing partition 4 and save costs. In an alternative embodiment, four electric push rods 6 can be provided and distributed at the four corners of the sealing partition 4.

[0053] like Figure 1 As shown, the air inlet 21 is in a square cylindrical shape, and the air inlet holes 22 are arranged on the four side walls of the air inlet 21. The air purification device can take in air from all sides and discharge air from the top, and the air volume is relatively large.

[0054] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
