[0028] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation, structure, features and effects of the air outlet and mist generating device and the disinfection machine proposed by the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures or characteristics in one or more embodiments may be combined in any suitable form.

[0029] The present invention provides a wind and mist device, as shown in the attached Figure 1 To Attachment Figure 8 As shown, it comprises a misting pool 3, which can form a liquid, such as a disinfectant, into a spray.

[0030] The air outlet and mist generating device comprises a fan (not shown in the drawings), and the mist generated by the mist generating pool 3 is blown into the space to be disinfected and sterilized by the airflow driven by the fan.

[0031] In a specific embodiment of the present invention, the air outlet mist generating device includes an outer tube 1, and the mist generating pool 3 is connected to the bottom of the outer tube 1; the mist generating pool 3 and the bottom of the outer tube 2 are preferably connected by an adhesive to make their interface sealed.

[0032] In a specific embodiment of the present invention, the wind and mist generating device comprises an inner tube 2; the inner tube 2 is sheathed together with the outer tube 1. The outer diameter of the inner tube 2 matches the inner diameter of the outer tube 1 so that the two can form a sandwich space 7 after being assembled; the sandwich space 7 is connected to the tube cavity 8 of the inner tube.

[0033] In a specific embodiment of the present invention, the radial cross-sections of the outer tube 1 and the inner tube 2 are circular.

[0034] In a specific embodiment of the present invention, the areas of the interlayer space 7 and the lumen 8 of the inner tube in the radial cross section of the inner tube are substantially equivalent so that the air flow velocity therein is stable and uniform.

[0035] The air outlet and mist generating device includes an air inlet 4 and an air outlet 5. The air inlet 4 is arranged at the top of the outer tube 1 and the inner tube 2, and is connected with the tube cavity 8 of the inner tube after penetrating the tube walls of the two; the tube cavity of the inner tube is generally also referred to as the first air duct. The air outlet 5 is arranged at the top of the air outlet and mist generating device and is connected with the interlayer space 7; the interlayer space is generally also referred to as the second air duct. Under the action of the fan, the air enters the first air duct 8 from the air inlet 4 and blows downward. When reaching the bottom of the first air duct, the airflow diffuses to the periphery, and the dry mist carrying the mist generating pool 3 rotates and rises along the second air duct 7 clockwise or counterclockwise, and finally blows the dry mist out from the top through the air outlet 5.

[0036] The air outlet and mist generating device comprises a cyclone blade 6; the cyclone blade 6 is arranged at the bottom of the interlayer space 7 and connected to the wall of the inner tube 2 or the outer tube 1. The spray formed by the mist generating pool 3 is carried by the airflow and passes through the cyclone blade 6 for particle size screening. The spray with small particle size, i.e. dry mist, is carried by the airflow and blown out from the air outlet; the droplets with large particle size are thrown to the wall of the interlayer space 7 and flow back to the mist generating pool 3.

[0037] The fan sucks in air, and forms an airflow in the air outlet mist generating device that flows through the air inlet 4, the inner tube cavity 8, the interlayer space 7 and the air outlet 5 in sequence; the airflow blows the spray formed in the mist generating pool 3 out of the air outlet 5. Under the action of the fan, a folded airflow from air ① to the spray ② blown out of the air outlet can be formed in the air outlet mist generating device; the air enters the air outlet mist generating device from the air inlet 4, passes through the tube cavity 8 of the inner tube 2, the cyclone blades 6, and the interlayer space 7 formed by the inner tube and the outer tube to the air outlet 5 and then blows out.

[0038] 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.

[0039] Preferably, the distance between the air inlet and the mist generating pool is ≥130mm; meanwhile, the height of the air outlet mist generating device is 170mm-210mm. The present invention ensures that the distance between the air inlet and the mist generating pool, that is, the length of the first air duct is ≥130mm, through the design of the folded air path. The spray is then blown out through the second air duct after cyclone screening, thereby achieving the design of the overall height of the air outlet mist generating device being 170mm-210mm, thereby being able to manufacture an air outlet mist generating device with a compact overall size.

[0040] The air outlet and mist generating device comprises a top plate 9. The top plate 9 is arranged at the top end of the inner tube 2. The top end of the inner tube 2 is closed by the top plate 9. The top plate 9 covers the inner tube 2 and protrudes from the inner tube 2.

[0041] Preferably, the top plate 9 is of square design. Positioning holes are provided at the four corners of the top plate 9 for connecting and fixing the top plate 9 with the housing of the sterilizer.

[0042] Preferably, an air outlet 5 is provided on the top plate 9 protruding from the outer periphery of the inner tube 2. The air outlet 5 is connected to the interlayer space 7 through a channel. The channel 10 through which the air outlet 5 is connected to the interlayer space 7 is provided at the top end of the outer side surface of the inner tube 2.

[0043] In order to make the blown air evenly distributed, the air outlets are generally arranged in multiple and evenly spaced positions; however, too many air outlets will affect the arrangement of the channel 10. Preferably, the number of the air outlets is 6 to 10; each air outlet has the same shape and size and is spaced at equal intervals. It is further preferred that the number of the air outlets is 8.

[0044] Preferably, the cross-section of the air outlet is fan-shaped.

[0045] The area of ​​the air outlet can be calculated by the height (radial length) of the fan and the arc angle corresponding to the fan. The area of ​​the air outlet will affect the wind speed of the air outlet misting device, so in actual application, the arc angle and height corresponding to each air outlet can be calculated according to the target wind speed.

[0046] Preferably, the angle formed by the channel connecting the air outlet and the interlayer space and the axis of the inner tube is 45° to 60°.

[0047] The wind in the interlayer space rises in a spiral clockwise or counterclockwise direction, so the channel is also set at a certain angle. At the same time, considering the number of channels, the present invention preferably sets the channel connected to the air outlet to be tilted up by 45 to 60 degrees, that is, the angle formed by the axis of the channel and the axis of the inner tube is 45 to 60 degrees, which is represented by β in the attached figure.

[0048] Preferably, the cyclone blades 6 are evenly arranged along the bottom end of the outer side surface of the inner tube 2; and the arc angle spacing between each cyclone blade is 30° to 60°.

[0049] The cyclone blades 6 are fixedly arranged on the outer surface of the inner tube 2 at the bottom of the interlayer space 7; the cyclone blades 6 are evenly arranged so as to cover the bottom periphery of the outer tube wall of the inner tube. The cyclone blades 6 are preferably arranged in 6 to 12 pieces, and the interval between each piece is 30° to 60°. 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 cross section of the inner tube. When the wind outlet and mist generating device is in operation, the cyclone blades 6 are fixed and do not rotate, but the wind rotates and rises along the gaps between the cyclone blades 6. The wind passes through the gaps between the cyclone blades to perform particle size screening, and the dry mist is carried by the wind and blown out from the air outlet, while the large particle droplets flow back into the mist generating pool through the gaps between the cyclone blades.

[0050] Preferably, the angle between the cyclone blade and the radial cross section of the inner tube is 30° to 45°.

[0051] 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 cross section of the inner tube refers to the angle formed by the tangent direction of the cyclone blade and its projection in the radial cross section of the inner tube, which is represented by α in the attached figure. 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 spirally rise 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 tube wall surface of the interlayer space and flow back to the mist generating pool from the gaps between the cyclone blades.

[0052] 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 +y 2 ) 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.

[0053] The present invention further provides a disinfection machine, which comprises a shell, in which the above-mentioned air outlet and mist generating device is arranged.

[0054] 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.

[0055] 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.

[0056] The structure and technical effects thereof are explained below through more specific embodiments.

[0057] The air outlet mist device described in this embodiment, wherein the mist pool adopts the company's existing products (available on the market), and the liquid used for misting adopts pure water. The outer tube is a cylindrical tube body with a height of 144mm; the inner tube is also a cylindrical tube body, one end of which is a top plate and the other end is open; the total height from the top plate to the bottom opening is 150mm; 12 cyclone blades are fixedly arranged on the outer side wall of the inner tube opening end, and the 12 cyclone blades are equally spaced, and the angle between them and the radial cross section of the inner tube is 30°; the inner tube and the outer tube are sheathed together to form a sandwich space; the outer diameter of the inner tube is 45mm, and the inner diameter of the outer tube is 65mm; eight fan-shaped air outlets on the top plate are connected to the sandwich space, and the air outlet spacing is uniform; the channel angle connecting the sandwich space is 45°; eight air inlets are arranged at the top of the outer tube and the inner tube to enter the inner tube cavity; the air inlet and the air outlet are staggered; the mist pool is bonded to the bottom of the outer tube; the height from the top plate to the bottom of the mist pool is 206.5mm.

[0058] The above-mentioned air outlet mist device was subjected to a spray test, and the test method was carried out using the conventional test method in the art. The evaporation amount and particle size of the air outlet mist device at different air volumes were detected by adjusting the air volume, and the results are shown in Table 1 below. The evaporation amount and particle size values ​​recorded in the table are the average values ​​of multiple tests.
