Detailed Description

Referring to fig. 1 to 5, which show the specific structure of the preferred embodiment of the present invention, a bladeless air purifying and separating fan includes a base 10 and a post flow back spray flow expanding nozzle 20, wherein a drawer-type filtering structure is disposed on the base 10.

The base 10 is simple and small, and includes a housing 11, a turbine core 12, and an air filter 13. From the arrangement, the housing 11 is hollow with sealed periphery, the bottom of the housing 11 is an air inlet 111, and the top is an air outlet 112. The turbine core 12 and the air filter 13 are installed in the housing 11, the turbine core 12 sucks air from the air inlet 111 and blows out from the air outlet 112, and the air filter 13 is located below the turbine core 12.

More specifically, the bottom of the housing 11 has a bottom plate 113, a filter installation cavity 114 is formed in the bottom plate 113, and the air filter 13 is mounted at the filter installation cavity 114 to isolate the air duct 115 between the air inlet 111 and the turbine core 12. Different from the traditional side air intake, the air intake 111 of the present design is located at the bottom of the housing 11, and the intake air is blown out from the air outlet 112 after passing through the air filter 13 at the bottom, so that the base 10 has the following advantages: firstly, the structure is simple, the base 10 only comprises a shell 11, a turbine core machine 12 and an air filter 13, the assembly is easy, and during the assembly, the turbine core machine 12 only needs to be assembled into the shell 11 from the bottom upwards, and then the air filter 13 is inserted from the position of an air inlet 111.

As shown in fig. 5, in this embodiment, the bottom plate 113 of the housing 11 is a square structure, and the corresponding drawer 131 is a square body. Alternatively, the structure may be circular. The air filter 13 is a side-drawer quick-change structure, and the air filter 13 is slidably and slidably fitted in the filter mounting cavity 114 of the chassis 113. The air filter 13 is more convenient to replace and clean due to the structural design, the air filter 13 is connected with the shell 11 without screws, and the air filter can be drawn out slightly and is convenient to use.

The air filter 13 includes a drawer 131 and a filter cartridge 132. The cartridge 132 is mounted in the cartridge receiving chamber 1313 of the drawer 131. More specifically, as shown in fig. 5, the drawer 131 has four side plates 1311 and a bottom plate 1312, a filter element accommodating chamber 1313 is defined between the four side plates 1311 and the bottom plate 1312, an air inlet 111 is formed in one side plate 1311, and the air inlet 111 is located below the filter element 132.

In order to realize uniform air inlet, a baffle 1314 is arranged on the bottom plate 1312 along the air inlet direction to divide the inlet air into uniform multiple channels, and the filter element 132 is supported on the baffle 1314. This design may allow for more uniform intake air and take full advantage of the filtering capabilities of the filter element 132 at each location.

And sliding chutes 14 are arranged on two sides of the filter mounting cavity 114, and are matched with two side walls of the drawing box 131 to form a sliding connection. Of course, the matching structure of the sliding rail and the pulley can also be designed.

The utility model discloses a product theory of operation and use as follows:

referring to fig. 3 and 4, air enters from an air inlet 111 at the bottom of the base 10, is filtered by the air filter 13, is drawn into the turbine core 12, and is sprayed into the columnar flow back-spraying flow-expanding nozzle 20 from an air outlet 112 at the top of the base 10, and is pressurized by the columnar flow back-spraying flow-expanding nozzle 20 to form a rapid air flow, and is sprayed out from the back jet orifice and/or the front jet orifice to form outlet air. After the head shaking function is started, the base 10 is not moved, the whole columnar flow back spraying flow expanding nozzle 20 can rotate and shake head relative to the base 10360 degrees, a three-dimensional 360-degree air outlet effect is formed, and the defect that the current common fan can only shake head within a small angle range is overcome.

After the service life of the air filter 13 of the present product is reached, only the drawing box 131 needs to be drawn out slightly, and the filter element 132 needs to be replaced. The air can be fresher by re-pushing into the filter mounting chamber 114. This air filter 13 is of drawer design and has the advantage of being quickly drawn out and pushed in, and easy to clean and replace. Secondly, air cleaner 13 no longer is traditional cylinder tubbiness, the utility model discloses the lid is flat-plate, and at first this kind of flat-plate filter is changeed in production/purchase to the cost is reduced, and the wind channel 115 between air intake 111 and the turbine core machine 12 is kept apart to flat-plate air cleaner 13 of on the other hand, and the air gets into from the bottom behind air cleaner 13, directly leads to turbine core machine 12, makes whole wind channel 115 more directly relatively speaking, turns round less, thereby increases the intake.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
