Description

Technical Field

[0001] The utility model relates to the field of air purifiers, in particular to an air purifier with a large-area fluid inlet. Background Art

[0002] Air purifier, also known as "air cleaner", air refresher, or purifier, is a product that can adsorb, decompose or transform various air pollutants and effectively improve the cleanliness of the air.

[0003] However, the fluid inlet of existing air purifiers is generally small, so the fluid filtration between it and the space will also be reduced. Especially for some pet households, there are many floating objects (such as hair) in the air, which affects the efficiency of air filtration.

[0004] Although there are air purifiers that use large-area fluid inlets, in actual use, there is a problem of flow pressure difference between the setting of the flow channel and the coordination with the fan, such as Chinese patent CN202322414093.X. Therefore, it is easy to generate noise and foreign matter cannot be stably adsorbed on the filter net. The main factor is that the length of the flow channel is too short. Utility Model Content

[0005] The main purpose of the utility model is to propose an air purifier with a large-area fluid inlet, aiming to improve the structure of the air purifier, and to improve the efficiency of air filtration by improving the design of the flow channel and the fan, while reducing noise.

[0006] To achieve the above objectives, the present invention provides an air purifier with a large-area fluid inlet, comprising:

[0007] A housing, wherein the housing has an inner cavity, an outer wall of the housing has a first opening, a positioning portion is provided in the inner cavity near the first opening, and the positioning portion has a positioning groove extending therethrough;

[0008] The top wall of the housing is provided with a second opening, the first opening being a fluid inlet, and the second opening being a fluid outlet;

[0009] a turbofan, wherein the side wall of the turbofan is provided with an air inlet opposite to the positioning groove, the top of the turbofan is provided with an air outlet, the inner cavity is away from the positioning portion to form a fluid channel, and the upper end of the fluid channel is connected to the second opening;

[0010] The positioning groove is provided with a first filtering device.

[0011] In the actual design, negative pressure is formed in the center of the turbofan, which causes the fluid to be transported upward from the first opening through the first filter device, so that particulate matter can be stably attached to the first filter device. At the same time, wind pressure is generated at the periphery of the turbofan, which causes the fluid to move upward and cooperates with the fluid channel to effectively increase the flow length of the fluid, thereby reducing noise.

[0030] The turbofan 2 has an air inlet 21 on its sidewall opposite to the positioning groove 12, and an air outlet 22 at its top. The inner cavity 10, away from the positioning portion 11, forms a fluid passage 23, and the upper end of the fluid passage 23 is connected to the second opening 1b.

[0031] The positioning groove 12 is provided with a first filtering device 3. Of course, a second filtering device may also be provided between the fluid channel 23 and the second opening 1b.

[0032] In the actual design, negative pressure is formed at the center of the turbofan 2, so that the fluid is transported upward from the first opening 1a through the first filter device 3, so that the particulate matter can be stably attached to the first filter device 3. At the same time, wind pressure is generated at the periphery of the turbofan 2, so that the fluid moves upward, and cooperates with the fluid channel 23 to effectively increase the flow length of the fluid, thereby reducing noise and improving the purification efficiency and stability of the air purifier.

[0033] Specifically, the shell 1 is in a long and flat shape, and the first opening 1a is provided at a longer side wall of the shell 1, thereby providing a larger fluid inlet area at a thinner thickness, thereby facilitating the storage and use of the machine.
