[0001] The invention relates to the technical field of air purification equipment, in particular to an air purifier wind guide structure and an air purifier. Background Art

[0002] In recent years, outdoor air pollution has become increasingly serious, especially with the rampant spread of the new coronavirus, and people spend most of their time indoors. However, indoor air has poor mobility and is easily polluted. As people's health awareness increases, more and more people are installing air purifiers indoors to purify indoor air and improve indoor air cleanliness.

[0003] The structure of the air purifier of the prior art generally includes a housing and a volute fan arranged in the housing, etc., the housing is provided with an air inlet and an air outlet, an air purification component is arranged between the air inlet and the volute fan, and an air duct is formed between the air outlet end of the volute fan and the air outlet. The indoor air enters the air purification component through the air inlet, is compressed by the volute fan, and blown out from the air outlet through the air duct. The air purification component can also be arranged in the air duct, and the air purification component generally refers to an air filter, a negative ion generator, an ultraviolet component, etc. The air purifier of the prior art is generally a single fan and a single air outlet. In order to improve the indoor air purification efficiency, two air outlets are arranged, and the two air outlets are located on the same side of the housing. The air volume, wind speed and wind pressure of the air blown out of the two air outlets are equal, so that the wind blown out of the two air outlets will not interfere with each other in the area close to the air outlet, so that the air outlet range of the air purifier is small, and the circulation effect of the indoor air is poor, and the purification efficiency is low. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned prior art and provide an air guide structure for an air purifier with a large air outlet range and good indoor air circulation effect.

[0005] The technical solution of the present invention is to provide an air purifier air guide structure having the following structure: it comprises a housing having an air inlet and two air outlets;

[0006] The fan is arranged in the housing, and the air inlet end of the fan is connected to the air inlet, the air outlet end of the fan is connected to the two air outlets, and an air duct for air outlet is formed between the air outlet end of the fan and the two air outlets;

[0007] The air distribution member is movably arranged in the air duct and is used to adjust the air volume of the two air outlets so that the air volume of the two air outlets is different.

[0008] After adopting the above structure, the air guide structure of the air purifier of the present invention has the following advantages compared with the prior art: the air guide structure of the air purifier is provided with a movable air divider in the air duct, and the air divider can adjust the air outlet volume of the two air outlets so that the air outlet volume of the two air outlets is different, that is, the air outlet volume of one air outlet is large, and the air outlet volume of the other air outlet is small; in this way, the wind pressure of the wind blown out from the two air outlets is different, and there is a pressure difference between the two. The wind blown out from the two air outlets generates air circulation in the area close to the two air outlet accessories, forming a microcirculation in the local space to generate an air flow vortex, thereby increasing the range of the wind blown out from the air outlet, so that the indoor air circulation effect is good and the air purification efficiency is high.

[0009] Preferably, the housing is rotatably connected to an adjustment plate, and the air distributor is connected to the adjustment plate and is used to rotate synchronously with the adjustment plate. This arrangement makes it easier to adjust the adjustment plate. When the air distributor rotates with the adjustment plate toward an air outlet, the air volume of the air outlet decreases, and vice versa. Of course, the air distributor can also move in parallel.

[0010] Preferably, one end of the adjustment plate extends out and is arranged outside the housing, so that it is convenient to manually rotate the adjustment plate, thereby making it more convenient to adjust the position of the air distribution member.

[0011] Preferably, a limiting protrusion is provided on the outer wall of one end of the adjusting plate extending out of the shell, and the limiting protrusion always abuts against the outer wall of the shell when the adjusting plate rotates. The setting of the limiting protrusion on the adjusting plate makes the adjusting plate rotate more steadily and smoothly when the adjusting plate rotates.

[0012] Preferably, the air distributor is arranged in an arc shape, and the center line of the air distributor coincides with the center line of the fan. In this way, the rotation center of the air distributor coincides with the rotation center of the fan, so that when the wind blown out of the fan outlet meets the air distributor, no large wind noise is generated, thereby making the air purifier low in noise and providing a good user experience.

[0013] Preferably, both ends of the air distribution member are folded outward to form an air guide portion. The arrangement of the air guide portion further reduces wind resistance and wind noise, thereby making the air purifier low in noise.

[0014] Preferably, the fan includes a motor and an impeller, the adjustment plate is provided with a groove for installing the motor, the outer wall of the groove forms a mounting portion for installing the impeller, the motor is connected in the groove and the motor shaft is drivingly connected to the impeller. This arrangement makes the air purifier compact and simple, and also reduces the overall volume, saving installation space.

[0015] Preferably, an arc-shaped convex wall is provided on the inner wall of the shell at the outer edge of the fan, and the two ends of the arc-shaped convex wall form the two air outlets, and the air duct is formed between the air outlet end of the fan and the inner wall of the arc-shaped convex wall, and the air distribution member is arranged in the air duct between the two air outlets. This arrangement makes the layout of the fan, the air duct and the air distribution member more reasonable, and makes the adjustment of the air volume more convenient.

[0016] Another technical solution of the present invention is to provide an air purifier having the following structure: it includes a filter assembly and a control unit, the filter assembly is arranged in the shell and located at the air inlet, and it also includes an air purifier air guide structure as described in any of the above technical solutions.

[0017] After adopting the above structure, the air purifier of the present invention has the following advantages compared with the prior art: the air purifier can adjust the air volume of the two air outlets to make the air volume of the two air outlets different; in this way, the wind pressure of the wind blown out from the two air outlets is different, and there is a pressure difference between the two. The wind blown out from the two air outlets generates air circulation in the area close to the two air outlet accessories, forming a microcirculation in the local space to generate an air flow vortex, thereby increasing the range of the wind blown out from the air outlet, so that the indoor air circulation effect is good and the air purification efficiency is high.

[0018] Preferably, the filter assembly includes a left filter and a right filter, and the two side walls of the housing are provided with sockets for plugging the left filter and the right filter, respectively, and the left filter and the right filter are detachably connected to the sockets on the two side walls of the housing. This arrangement not only facilitates the disassembly, assembly and replacement of the left filter and the right filter, but also makes full use of the space in the housing.

[0019] Preferably, a pull-out bracket is movably inserted into the sockets on the two side walls of the housing, and the left filter and the right filter are movably connected to the bracket. This arrangement makes it more convenient to disassemble, assemble and replace the left filter and the right filter.

[0020] Preferably, the housing is provided with a hanging hole, and a hanging rack is hung on the hanging hole. The setting of the hanging rack allows users to store items on the desktop, thereby improving the item storage capacity of the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] See also Figure 1 to Figure 5As shown, the present invention is an air guide structure of an air purifier, which includes a shell 1, which has an air inlet 100 and two air outlets 102; the air inlet 100 is connected to an air inlet grille 101, and the two air outlets 102 are located on the same side of the shell 1 and are arranged close to the user, and there is a gap between the two air outlets 102; a fan 2 is arranged in the shell 1, and the fan 2 is an axial flow fan 2, and the air inlet end of the fan 2 is connected to the air inlet 100, the air outlet end of the fan 2 is connected to the two air outlets 102, and an air duct 103 for air outlet is formed between the air outlet end of the fan 2 and the two air outlets 102; the structure of the fan 2 generally includes a motor 200 and an impeller 201, the end of the impeller 201 close to the air inlet 100 is the air inlet end, and the circumferential side wall of the impeller 201 is the air outlet end. The air guiding structure of the air purifier also includes an air dividing member 3 arranged in the air duct 103, and the air dividing member 3 is movably arranged in the air duct 103. The air dividing member 3 moves in the air duct 103 between the two air outlets 102, and is used to adjust the air outlet volume of the two air outlets 102 so that the air outlet volume of the two air outlets 102 is different; that is, the air outlet volume of one air outlet 102 is large, and the air outlet volume of the other air outlet 102 is small; in this way, the wind pressure of the wind blown out from the two air outlets 102 is different, and there is a pressure difference between the two. The wind blown out from the two air outlets 102 generates air circulation in the area near the two air outlets 102, forming a microcirculation in the local space to generate an air flow vortex, thereby increasing the range of the wind blown out from the air outlet 102, so that the indoor air circulation effect is good and the air purification efficiency is high.

[0032] See also Figure 1 , Figure 2 and Figure 5 As shown, as an embodiment of the present invention; an adjustment plate 4 is rotatably connected to the housing 1, and the air distribution member 3 is connected to the adjustment plate 4 and is used to rotate synchronously with the adjustment plate 4. This makes the adjustment of the adjustment plate 4 more convenient. When the air distribution member 3 rotates with the adjustment plate 4 toward an air outlet 102, the air outlet of the air outlet 102 decreases, and vice versa. The air outlet of the air outlet 102 increases; of course, the movement mode of the air distribution member 3 can also be parallel movement, that is, a slidable air distribution member 3 is provided in the air duct 103 between the two air outlets 102, and the air distribution member 3 can slide toward the two air outlets 102 to block the air volume flowing into the air outlet 102. The movement of the air distribution member 3 can be manually driven or electrically driven. In this embodiment, manual drive is adopted. Specifically, one end of the adjustment plate 4 is extended and arranged on the outside of the housing 1 for manual movement of the adjustment plate 4. In order to make the adjustment plate 4 rotate more smoothly, a limiting protrusion 400 is provided on the outer wall of the end of the adjustment plate 4 extending out of the shell 1 . The limiting protrusion 400 always abuts against the outer wall of the shell 1 when the adjustment plate 4 rotates.

[0033] See also Figure 1 and Figure 3As shown, as an embodiment of the present invention, the air splitter 3 is arranged in an arc shape, and the center line of the air splitter 3 coincides with the center line of the fan 2. The rotation center of the air splitter 3 coincides with the rotation center of the fan 2, so that the wind blown out of the air outlet of the fan 2 will not generate a large wind noise when it meets the air splitter 3, so that the air purifier has low noise and good user experience. In order to reduce the resistance when the airflow at the air outlet of the fan 2 meets the air splitter 3 and to facilitate the airflow at the air outlet of the fan 2 to enter the air outlet 102 more smoothly, both ends of the air splitter 3 are folded outward to form an air guide 300.
