[0037] The air outlet and mist generating device comprises a cyclone blade 5 ; the cyclone blade is arranged at the bottom of the interlayer space 13 and connected to the side wall of the first inner tube 3 or the second inner tube 4 .

[0038] The shell 1, the air inlet 2, the first inner tube 3, the second inner tube 4, the cyclone blades 5 and the air outlet 6 together constitute an upper tube; the air inlet 1 and the air outlet 6 are respectively located at opposite ends of the upper tube; the bottom of the upper tube is connected to the mist generating pool 7; the upper tube and the mist generating pool together constitute the air outlet and mist generating device.

[0039] The space between the shell 1 and the second inner tube 4 is also called the first air duct 11; under the action of the fan, the air ① entering the shell 1 from the air inlet 2 flows upward in the first air duct 11.

The interlayer space 13 is also called the third air duct; the airflow from the second air duct 12 carries the spray from the mist generating pool 7, and after the particle size is screened by the cyclone blades 5, the dry mist enters the third air duct 13 and flows upward. After reaching the air outlet 6, the airflow blows the dry mist ② blown out by the airflow to the target space, and the droplets with larger particle sizes flow back into the mist generating pool. That is, under the action of the fan, the air forms a three-fold airflow in the air outlet and mist generating device, the air ① enters the first air duct 11 from the air inlet 2 and blows toward the top, and enters the second air duct 12 along the top and blows downward, and diffuses toward the periphery when it reaches the bottom of the second air duct, and after the dry mist in the mist generating pool is screened by the cyclone blades, it rotates and rises along the third air duct 13, and finally blows the dry mist ② out from the side through the air outlet 6. In the third air duct, the airflow spirals upward in a clockwise or counterclockwise direction.

[0040] In a specific embodiment of the present invention, the radial cross-sections of the first inner cylinder 3 and the second inner cylinder 4 are circular.

[0041] In a specific embodiment of the present invention, the shell 1 also includes a top cover 8; a first splash-proof ring 81 is arranged on the inner side of the top cover 8; the first splash-proof ring 81 has the same shape as the top opening of the first inner tube 3, and the centers coincide with each other; the size of the first splash-proof ring 81 is larger than the size of the top opening of the first inner tube 3.

[0042] In a specific embodiment of the present invention, the top cover 8 is detachably connected to the shell 1. The top cover 8 is square in design, and upper positioning holes are provided at its four corners; lower positioning holes are also provided at the four corners of the shell 1; the top cover 8 and the shell 1 can be connected by screws. A first splash-proof ring 81 is provided on the inner side of the top cover 8; the first splash-proof ring 81 is provided in the middle part of the top cover 8, and its diameter is larger than the size of the top opening of the first inner tube; after the top cover 8 and the shell 1 are installed, the ring body of the first splash-proof ring 81 should be located at the outer periphery of the top opening of the first inner tube to prevent the liquid in the wind-discharging and mist-generating device from splashing from the top opening of the first inner tube and causing overflow.

[0043] In a specific embodiment of the present invention, the top of the second inner tube 4 is connected to the top of the first inner tube 3 via a connecting plate 31; a second splash-proof ring 32 is provided on the connecting plate 31; the second splash-proof ring 32 has the same shape as the first splash-proof ring 81, and the center coincides; the size of the second splash-proof ring 32 is larger than the size of the first splash-proof ring 81. The size of the second splash-proof ring 32 matches that of the first splash-proof ring 81, and can jointly avoid the problem of liquid splashing in the wind-out mist-generating device, and effectively prevent the liquid in the wind-out mist-generating device from splashing from the top opening of the first inner tube and causing overflow.

[0044] In a specific embodiment of the present invention, the first inner cylinder 3, the second inner cylinder 4, the connecting plate 31 and the second anti-splash ring 32 are integrally formed.

[0045] In a specific embodiment of the present invention, the first inner cylinder 3, the second inner cylinder 4, the connecting plate 31, the second anti-splash ring 32 and the cyclone blades 5 are integrally formed.

[0046] In a specific embodiment of the present invention, the gap between the first splash-proof ring 81 and the connecting plate 31, the gap between the first splash-proof ring 81 and the second splash-proof ring 32, and the gap between the second splash-proof ring 32 and the top cover 8 are matched in size or are of comparable size. The purpose of controlling the sizes of the above three gaps to match or be comparable in size is to control the wind speed through the narrow gap formed by the gaps to stabilize the airflow speed. Preferably, the gap is 1.5 to 5 mm. Preferably, the gap is 2 to 3 mm. The airflow of the first air duct sequentially passes through the gap between the second splash-proof ring and the top cover, the gap between the first splash-proof ring and the second splash-proof ring, and the gap between the first splash-proof ring and the connecting plate to enter the second air duct.

[0047] In a specific embodiment of the present invention, the gap between the first splash-proof ring 81 and the connecting plate 31, the gap between the first splash-proof ring 81 and the second splash-proof ring 32, and the gap between the second splash-proof ring 32 and the top cover 8 are equal in size.

[0048] In a specific embodiment of the present invention, the sum of the height of the first anti-splash ring 81 and the height of the second anti-splash ring 32 is greater than the distance between the top cover 8 and the connecting plate 31. The first anti-splash ring and the second anti-splash ring cooperate with each other through the height of the ring body to effectively prevent liquid from splashing out.

[0049] In a specific embodiment of the present invention, the first inner cylinder is a tapered cylinder with a size gradually decreasing from top to bottom; the height of the first inner cylinder is ≥85mm. The inner cavity of the first inner cylinder is a tapered cylinder, the inner diameter of the top opening is larger than the inner diameter of the bottom opening; the inner cavity wall is a smooth surface with a continuously changing size. One purpose of setting the inner cavity to a cone in the present invention is to increase the volume of the fog zone so that it can be fully atomized within a limited height range; the second purpose is to reduce the rotating wind speed; the third purpose is to facilitate the backflow of droplets generated when the spray impacts.

[0050] According to the above technical solution, the air outlet mist generating device proposed in the present invention can fold the airflow to save its height space. On the one hand, the folded airflow can satisfy the requirement that a sufficient distance must be maintained between the air inlet and the mist generating pool to reduce the spray formed in the mist generating pool from being disturbed by the airflow and thus reducing the energy and efficiency of the spray. On the other hand, it can also provide enough space to blow the dry mist formed in the mist generating pool through cyclone particle size screening from the air outlet, thereby ensuring the steam volume and spray efficiency of the air outlet mist generating device.

[0051] Preferably, the height of the first inner cylinder and the second inner cylinder is ≥85mm; meanwhile, the height of the air outlet and mist generating device is 130mm-180mm. The present invention ensures that the distance between the top opening of the first inner cylinder and the mist generating pool, that is, the length of the second air duct is ≥85mm, through the design of the folded air path, so that the spray is sieved by the cyclone and then blown out through the third air duct, thereby realizing the design of the overall height of the air outlet and mist generating device being 130mm-180mm, thereby being able to manufacture an air outlet and mist generating device with a compact overall size.

[0052] In a specific embodiment of the present invention, one end of the air outlet connected to the second inner tube is an oblique insertion port, and the other end is a flat end port; the inner diameter of the air outlet gradually decreases from the oblique insertion port to the flat end port.

[0053] In a specific embodiment of the present invention, the air outlet is a square tube with a rectangular cross section including four sides, one end of which is a flat end and the other end is an oblique plug; among the four sides constituting the oblique plug, one side of a group of opposite sides is longer than the other side; the other group of opposite sides are all arc-shaped edges, and the arc-shaped edges connect the longer side with the shorter side to form a smooth oblique plug. One end of the air outlet connected to the second inner tube is set as an oblique plug, the purpose of which is to control the angle of connection between the two so that the air outlet of the third air duct is smooth. The inner diameter of the air outlet gradually decreases from the oblique plug to the flat end, and this gradually shrinking design is intended to gradually increase the wind speed at the outlet.

[0054] In a specific embodiment of the present invention, the air outlet and mist generating device comprises a cyclone blade 5; the cyclone blade 5 is arranged at the bottom of the interlayer space 13 and connected to the wall of the first inner tube 3 or the second inner tube 4. The spray formed by the mist generating pool 7 is carried by the airflow and passes through the cyclone blade 5 for particle size screening. The spray with a small particle size, i.e., dry mist, is carried by the airflow and blown out from the air outlet; the droplets with a large particle size are thrown onto the wall of the interlayer space 13 and flow back into the mist generating pool 7.

[0055] Preferably, the cyclone blades 5 are evenly arranged along the bottom end of the outer side surface of the first inner cylinder 3; and the arc angle spacing between each cyclone blade is 30° to 60°.

[0056] The cyclone blades 5 are fixedly arranged on the outer side of the first inner tube 3 at the bottom of the interlayer space 13; the cyclone blades 5 are evenly arranged so as to cover the bottom periphery of the outer side wall of the first inner tube 3. Alternatively, the cyclone blades 5 are fixedly arranged on the inner side of the second inner tube 4 at the bottom of the interlayer space 13; the cyclone blades 5 are evenly arranged so as to cover the bottom periphery of the inner side wall of the second inner tube 4.

[0057] The cyclone blades 5 are preferably arranged in 6 to 12 pieces, with an arc angle of 30° to 60° between each piece. The arc angle is measured by the central angle formed by the projections of the same position of two adjacent cyclone blades in the radial section of the inner cylinder. When the wind-discharging and mist-generating device is in operation, the cyclone blades 5 are fixed and do not rotate, but the wind rotates and rises along the gaps between the cyclone blades 5. The wind passes through the cyclone blades to screen the particle size, and the dry mist is blown out of the air outlet by the wind, while the large particle droplets flow back into the mist-generating pool through the gaps between the cyclone blades.

[0058] Preferably, the angle between the cyclone blade and the radial cross section of the inner cylinder (not shown in the figure) is 30° to 45°.

[0059] The setting angle of the cyclone blade is related to the air volume requirement of the air outlet and mist generating device, and can be adjusted within the range of 30° to 45° according to actual conditions. The angle between the cyclone blade and the radial section of the inner cylinder refers to the angle formed by the tangent direction of the cyclone blade and its projection in the radial section of the inner cylinder. The upward angle of the cyclone blade mainly serves to guide the wind. The design range of this angle can make the dry mist in the spray carried by the airflow spiral up along the interlayer space until it is blown out after the air outlet, while droplets with slightly larger particle sizes will be screened and thrown to the wall surface of the interlayer space and flow back to the mist generating pool from the gaps between the cyclone blades.

[0060] Preferably, the cyclone blade comprises an upper surface; at least one-half of the truncation lines of the upper surface have a curve shape as follows: (x 2 +y2 ) 2 -2x(x 2 +y 2 )+ny 2 =0, where x and y are the horizontal and vertical coordinates in the xy coordinate system, n is 8 to 10, x is 0.8 to 1.1, and y is a positive number. The truncation line described here represents the curve corresponding to the upper surface of the cyclone blade after the longitudinal section. The purpose of designing the upper surface of the cyclone blade into this shape is to use the streamline of the surface to reduce the resistance of the airflow when it flows through the gap, so that the spray can pass better, improve its particle size screening effect, and increase the steam volume.

[0061] The present invention further provides a disinfection machine, which comprises a shell, in which the aforementioned air outlet and mist generating device is arranged.

[0062] Preferably, according to the use space and area of ​​the sterilizer, a plurality of the above-mentioned air outlet and mist generating devices can be arranged in the sterilizer in an array.

[0063] Preferably, the array form of the air outlet mist generating devices is arranged in two rows, with 2 in each row; or the array form of the air outlet mist generating devices is arranged in two rows, with 3 in each row; or the array form of the air outlet mist generating devices is arranged in two rows, with 4 in each row; or the array form of the air outlet mist generating devices is arranged in three rows, with 3 in each row.

[0064] The structure and technical effects thereof are explained below through more specific embodiments.
