As shown in fig. 1, a household fresh air system includes an outer unit 31 installed outside a glass or wall, a cover 32 installed inside the glass or wall, and a pipeline 33 connecting the cover and the outer unit 31, the glass or wall is provided with a through hole 34 for the pipeline 33 to pass through, the cover 32 covers the through hole 34 and one end of the pipeline 33 and is provided with a vent 35 on the surface, a turbo fan 36 and a filter element 37 are installed inside the outer unit 31, an air inlet is formed on the surface of the turbo fan 36, and the air inlet is communicated with the turbo fan 36 through the filter element 37.

As shown in fig. 2, the filter element 37 is in a semicircular disc-shaped structure, one side of the filter element 37 is provided with a first channel port which is butted with the air inlet, the other side of the filter element 37 is provided with a second channel port which is connected with the turbo fan 36, air enters the filter element 37 through the first channel port and the air inlet, and the air passing through the filter element 37 is discharged to the turbo fan 36 through the second channel port. The above structure restricts the airflow formed by the outdoor air to firstly enter the filter element 37 of the outer unit 31, and then enter the air inlet of the turbo fan 36 after being filtered by the filter element 37. The filter element 37 is arranged to filter air entering from the external environment first to remove particles and dust in the air.

In the preferred structure of the present invention, the filter element 37 is provided with a filter net along its inner wall surface, and the filter net is repeatedly bent. The filter screen that folds repeatedly is piled up in filter core 37, can effectively increase the area of the filter screen that the air current passes through to realize good filter effect.

The turbo fan is shown in fig. 3: the turbine blade 2 comprises an outer shell 1, a turbine blade 2 and a guide support 3, wherein the turbine blade 2 comprises an inner cylinder 21 and a plurality of blades 22 distributed on the outer peripheral surface of the inner cylinder 21. Preferably, eight helical blades 22 are distributed on the outer peripheral surface of the inner cylinder 21. The inner cylinder 21 is of an inverted cone-barrel structure, and the peripheral surface of the inner cylinder is an inwards concave arc-shaped surface, so that the airflow entering the turbine fan blade 2 is guided in an arc shape.

As shown in fig. 4, the vane 22 is formed by spirally bending a quadrangular sheet member. The bottom surface of the lower end of the vane 22 is positioned at the bottom of the inner cylinder 21, and an included angle I is formed between the inclined surface of the bottom surface of the lower end of the vane 22 and the bottom surface of the inner cylinder 21, and the included angle I is smaller than 15 degrees. That is, the bottom surfaces of the lower ends of the vanes 22 and the bottom surface of the inner cylinder 21 are located approximately on the same plane. The bottom surface of the lower cylinder part 1b and the bottom surface of the turbine fan blade 2 form an air inlet 7, and the blades 22 are arranged at the air inlet 7 to divide the entering air flow into a plurality of small air flows. The turbine fan blade 2 rotates to drive a plurality of small air flows to rapidly generate vortex.

As shown in fig. 5, the casing 1 is formed by connecting an upper inverted circular truncated cone-shaped cylinder and a lower inverted circular truncated cone-shaped cylinder, the casing 1 is sleeved on the periphery of the turbine blade 2, a lower cylinder 1b of the invention is matched with the turbine blade 2 in structure, and a gap is formed between the inner wall surface of the lower cylinder 1b and the turbine blade 2. The air flow moving to the lower cylinder 1b is subjected to centrifugal force and moves toward the inner periphery of the lower cylinder 1b, where it enters the annular cavity of the casing 1 and then returns to the turbine blades 2 again, again circulating in the same manner from the beginning of the blades 22. The gap at this point of the invention is relatively small, enabling the gas stream to be rapidly compressed, creating a vortex.

Then, the diameter of the bottom surface of the upper cylinder 1a is larger than that of the top surface of the lower cylinder 1b, that is, the distance between the turbine fan blade 2 and the inner wall of the upper cylinder 1a is larger than that of the lower cylinder 1 b. The invention relates to a two-stage gas compression housing 1. Airflow enters from the bottom of the whole shell 1, and in the lower cylinder part 1b, the turbine fan blades 2 drive the airflow to rotate to generate vortex, and the compressed airflow generates wind pressure. When the gas is guided into the upper cylinder part 1a by the turbine blade 2, the space between the upper cylinder part 1a and the turbine blade 2 is increased, the vortex gas flow expands outwards on the upper cylinder part 1a, and larger and faster vortex is generated. Since the air flow is accelerated again, the air is blown out in the form of a spiral line by the circulating air flow generated when the turbine blade 2 rotates, so that the air leaves the air outlet with extremely high energy.

As shown in fig. 3 and 4, the top surface of the upper end of the vane 22 is located below the top surface of the cylinder, and an included angle two is formed between the top surface of the upper end and the top surface where the inner cylinder 21 is located, and the included angle two is greater than 60 degrees and smaller than 90 degrees. The top surface of the upper cylinder part 1a and the top surface of the turbine blade 2 form an air outlet. The top surface structure of the upper end of the blade 22 is arranged, so that the space at the air outlet is not separated by the blade 22, and the air flow has larger space to pass through the air outlet. And the air current in the shell 1 will converge at the air outlet to form an integral air current.

In addition, as shown in fig. 3, the guide bracket 3 of the present invention is engaged with the housing 1 and provided with a guide ring 5, and the air flow enters the housing 1 from below the housing 1 and is discharged after passing through the guide ring 5. I.e. the air flow coming out of the outlet will be acted upon again by the guide ring 5. The guide ring 5 is arranged on the periphery of the upper part of the guide support 3, the guide ring 5 comprises an inner ring, an outer ring and a guide sheet 6 for connecting the inner ring and the outer ring, the guide sheet 6 divides the guide ring 5 into a plurality of areas, and the guide sheet 6 is obliquely arranged. The angle of the guide vane 6 of the invention is in accordance with the circulation direction of the vortex air flow reaching the air outlet, the guide vane 6 enables the air flow to be continuously led out along the rotation direction, and the vortex flow state of the air flow is kept, so that the invention has high flow speed.

As shown in fig. 3, the inner cylinder 21 is connected to the brushless motor 4, the brushless motor 4 operates to drive the turbine blade 2 to rotate, and the brushless motor 4 is installed through the guide bracket 3. The invention carries out the following optimization design on the structure of the guide bracket 3, the lower part of the guide bracket 3 is in a cone-barrel-shaped structure and is lined in the inner barrel 21, and the brushless motor 4 is arranged on the guide bracket 3 and is partially positioned in the inner barrel 21. The contact surface between the guide support 3 and the turbine fan blade 2 is large, the matching degree is high, and the stability is high after installation. And through the design of the embedded guide bracket 3, the invention further reasonably and compactly connects all the parts in a matching way. The structure volume of the invention is effectively reduced.

As shown in fig. 3, in addition, the present invention also has a sterilization and purification function, the bottom of the housing 1 extends downward to form a mounting frame, at least one sterilization LED lamp 8 is mounted at the mounting frame, and the sterilization LED lamp 8 irradiates the air flow introduced into the air inlet 7. At least one ultraviolet LED lamp 9 is installed on the guide support 3, and the ultraviolet LED lamp 9 irradiates airflow guided out by the air outlet. The air flow entering the air purifier is irradiated, disinfected and purified by the sterilizing LED lamp 8 and the ultraviolet LED lamp 9, so that the air purification of the space environment where the air purifier is located is realized.

The outer periphery of the housing 1 is provided with a vibration damping mount 10. The invention is installed through the damping support, and reduces the noise caused by the work of the brushless motor 4 and the turbine fan blade 2.

The periphery of the bottom of the shell 1 is sleeved with the filter screen cylinder 11, and in the design process, designed air enters the filter screen cylinder after being filtered by the first layer of the filter screen cylinder 11 from the periphery of the filter screen cylinder 11 and then reaches the lower part of the shell 1 and can pass through the air inlet hole. The invention firstly filters the impurity, such as dust, from the sucked air through the structure of the filter screen cylinder 11.
