Various modifications and changes can be made by those skilled in the art to which the present application pertains without departing from the scope of the present application. Like reference numerals in the drawings denote like elements, and thus, repetitive descriptions on them will be omitted.

[0038] The words expressing position and direction described in the present application are described by taking the drawings as an example, but changes can also be made as needed, and the changes made are included in the protection scope of the present application.

[0039] Referring to Figures 1 to 7 , the present application provides a disinfection equipment 100, comprising: a shell 1 and a flow resistance device 2, the flow resistance device 2 is arranged in the shell 1.

[0040] Specifically, the shell 1 is in the shape of a cylinder as a whole, and of course, it can also be in other shapes. The shell 1 has a first end 11 and a second end 12 opposite in the axial direction of the shell 1, and the inside of the shell 1 has a containing cavity 13, which has a top 131 and a bottom 132 opposite in the direction perpendicular to the axis of the shell 1 and two opposite sides 133, for example, the front side and the back side of the containing cavity 13, and the shell 1 is provided with a water inlet 14 and a water outlet 15 communicating with the top 131 of the containing cavity 13, the water inlet 14 is arranged close to the first end 11 of the shell 1, and the water outlet 15 is arranged close to the second end 12 of the shell 1. The water flow enters the containing space through the water inlet 14 and then leaves the containing space through the water outlet 15.

[0041] The flow resistance device 2 is used to change the direction and flow rate of the water flow, and the flow resistance device 2 comprises a plurality of flow resistance plates which are arranged in the containing cavity 13 of the shell 1 in the axial direction. As a preferred mode, the plurality of flow resistance plates are arranged between the water inlet 14 and the water outlet 15.

[0042] When the water flow enters the containing space through the water inlet 14, the water flow impacts on the flow resistance device 2, and the plurality of spaced flow resistance plates can change the direction and reduce the flow rate of the water flow multiple times, which can more effectively change the direction and reduce the flow rate of the water flow, change the torrent into turbulent flow, make the water flow rate more uniform, prolong the time of the water flow in the containing cavity 13, ensure that the water flow receives a sufficient radiation dose, the radiation dose received by the water flow is more uniform, improve the disinfection and sterilization effect, compared with only one flow resistance plate, each flow resistance plate in the plurality of flow resistance plates can be smaller, which can reduce the cross-sectional area occupied in the containing cavity 13, improve the effective cross-sectional area of the containing cavity, ensure the flow of the water flow, improve the working efficiency of the disinfection equipment 100, also can reduce the impact force of the water flow impacting on the flow resistance device 2, avoid the disinfection equipment 100 generating vibration, ensure the disinfection equipment 100 running smoothly, prolong the service life of the disinfection equipment 100, and at the same time, also reduce the material cost of the flow resistance device 2.

[0043] In a specific embodiment, the plurality of flow resistance plates comprise a first flow resistance plate 21, a second flow resistance plate 22 and a third flow resistance plate 23 which are arranged in sequence and are spaced. The first flow resistance plate 21 is arranged close to the water inlet 14, and the third flow resistance plate 23 is arranged close to the water outlet 15. Through the three layers of flow resistance plates, the flow resistance device 2 can change the direction and reduce the flow rate of the water flow three times, which can change the torrent into turbulent flow, ensure that the water flow receives a sufficient radiation dose, the radiation dose received by the water flow is more uniform, improve the disinfection and sterilization effect. The material of the first flow resistance plate 21, the second flow resistance plate 22 and the third flow resistance plate 23 is preferably a rigid material, for example, stainless steel, etc., so as to avoid the first flow resistance plate 21, the second flow resistance plate 22 and the third flow resistance plate 23 from deforming when working, and ensure the disinfection equipment 100 running stably.

[0044] As a preferred mode, the first flow resistance plate 21 is arranged close to the bottom 132 of the containing cavity 13, for example, the bottom center of the first flow resistance plate 21 is close to the center of the bottom 132 of the containing cavity 13, the second flow resistance plate 22 is arranged close to the side 133 of the containing cavity 13, for example, the second flow resistance plate 22 is close to the center of the side 133 of the containing cavity 13, and the third flow resistance plate 23 is arranged close to the top 131 of the containing cavity 13, for example, the third flow resistance plate 23 is close to the center of the top 131 of the containing cavity 13. Since the water flow enters from the water inlet 14 of the top 131 of the containing cavity 13 and then flows out from the water outlet 15 of the top 131 of the containing cavity 13, the current will first concentrate on the bottom 132 of the containing cavity 13 close to the water inlet 14, then concentrate on the side 133 of the containing cavity 13, and finally concentrate on the top 131 of the containing cavity 13 close to the water outlet 15. The first flow resistance plate 21 arranged close to the bottom 132 of the containing cavity 13 can adjust the direction and flow rate of the current concentrated on the bottom 132 of the containing cavity 13 close to the water inlet 14. The second flow resistance plate 22 arranged close to the side 133 of the containing cavity 13 can adjust the direction and flow rate of the current concentrated on the side 133 of the containing cavity 13. The third flow resistance plate 23 arranged close to the top 131 of the containing cavity 13 can adjust the direction and flow rate of the current concentrated on the top 131 of the containing cavity 13 close to the water outlet 15. By arranging the flow resistance device 2 at the position where the current concentrates, the direction of the water flow can be changed more effectively and the flow rate of the water flow can be reduced, the irradiation time of the water flow is prolonged, the radiation dose received by the water flow is ensured to be sufficient, the radiation dose received by the water flow is more uniform, and the disinfection and sterilization effect is improved.

[0045] In a specific embodiment, the first flow resistance plate 21, the second flow resistance plate 22, and the third flow resistance plate 23 are all circular arc-shaped parallel to the radial cross section of the containing cavity 13, and the circular arc opening can coincide with the central axis of the containing cavity 13. The shape of the current formed by the water flow in the cylindrical shell 1 is more similar to the circular arc shape, and arranging the first flow resistance plate 21, the second flow resistance plate 22, and the third flow resistance plate 23 as circular arc-shaped can improve the effect of the flow resistance device 2 on changing the direction of the water flow and reducing the flow rate of the water flow.

[0046] The outer diameter of the first flow resistance plate 21, the outer diameter of the second flow resistance plate 22 and the outer diameter of the third flow resistance plate 23 are preferably equal to the inner diameter of the shell 1. That is, the outer edge of the first flow resistance plate 21, the outer edge of the second flow resistance plate 22 and the outer edge of the third flow resistance plate 23 match the inner wall of the shell 1, on the one hand, the outer edge of the first flow resistance plate 21, the outer edge of the second flow resistance plate 22 and the outer edge of the third flow resistance plate 23 can be tightly connected with the inner wall of the shell 1, which can better regulate the rapid flow close to the inner wall of the shell 1, on the other hand, it improves the bonding force between the outer edge of the first flow resistance plate 21, the outer edge of the second flow resistance plate 22 and the outer edge of the third flow resistance plate 23 and the inner wall of the shell 1, prolongs the service life of the flow resistance device 2, and also facilitates the installation of the first flow resistance plate 21, the second flow resistance plate 22 and the third flow resistance plate 23 on the shell 1. The first flow resistance plate 21, the second flow resistance plate 22 and the third flow resistance plate 23 are preferably arranged with the same center as the shell 1.

[0047] The width of the second flow resistance plate 22 and the width of the third flow resistance plate 23 are preferably greater than the width of the first flow resistance plate 21. In this embodiment, the width of the second flow resistance plate 22 and the width of the third flow resistance plate 23 are twice the width of the first flow resistance plate 21. When the water flow enters the containing cavity 13, the water flow first impacts the first flow resistance plate 21, reducing the width of the first flow resistance plate 21, which can reduce the impact force of the water flow impacting the first flow resistance plate 21, avoiding vibration of the disinfection equipment 100, ensuring smooth operation of the disinfection equipment 100, and prolonging the service life of the disinfection equipment 100. After the water flow is slowed down by the first flow resistance plate 21, the impact force of the water flow impacting the second flow resistance plate 22 and the third flow resistance plate 23 is greatly reduced, and the water flow impacting the second flow resistance plate 22 and the third flow resistance plate 23 will not produce vibration. Increasing the width of the second flow resistance plate 22 and the width of the third flow resistance plate 23 can improve the effect of the second flow resistance plate 22 and the third flow resistance plate 23 on changing the direction of the water flow and reducing the flow rate of the water flow, thereby improving the disinfection and sterilization effect of the disinfection equipment 100.

[0048] As a priority, the central angle of the first flow resistance plate 21 is 120°±20°, the central angle of the second flow resistance plate 22 is 60°±20°, the central angle of the third flow resistance plate 23 is 210°±20°, the number of the second flow resistance plate 22 is two, and the two second flow resistance plates 22 are symmetrically arranged on the two side portions 133 of the containing cavity. In the direction perpendicular to the axis of the shell 1, the cross-sectional area of the first flow resistance plate 21, the cross-sectional area of the second flow resistance plate 22 and the cross-sectional area of the third flow resistance plate 23 gradually increase. In this way, the vibration generated by the water flow impacting the flow resistance device 2 can be effectively reduced, and the effect of the flow resistance device 2 on changing the direction of the water flow and reducing the flow rate of the water flow can be improved, thereby improving the disinfection and sterilization effect of the disinfection equipment 100.

[0049] The second flow resistance plate 22 is provided with one or more through holes 221.

[0050] The plurality of sterilization lamps 3, for example, ultraviolet sterilization lamps, are arranged in the accommodating cavity 13 of the shell 1, and the two ends of the sterilization lamps 3 are connected with the first end 11 and the second end 12 of the shell 1, respectively. In the embodiment, the number of the sterilization lamps 3 is eight, and the eight sterilization lamps 3 are uniformly distributed in the accommodating cavity 13, so that the radiation amount of the water flow is more uniform.

[0051] With reference to Figures 8 to 15 , the technical effect of the present application is shown by testing the water flow speed and the torrential flow speed of the sterilization equipment 100 of Comparative Example 1 and Examples 1-3. The only difference between the sterilization equipment 100 of Comparative Example 1 and Examples 1-3 is the flow resistance device 2. Comparative Example 1 does not have a flow resistance plate, Example 1 only has the first flow resistance plate 21, Example 2 has the first flow resistance plate 21 and the second flow resistance plate 22, and Example 3 has the first flow resistance plate 21, the second flow resistance plate 22, and the third flow resistance plate 23. Comparative Example 1 and Examples 1-3 are tested under the same test conditions.

[0058] The diameter of the through hole 221 is 1.5 mm;

[0059] The diameter of the sterilization lamp 3 is 2.3 mm, and the number of the sterilization lamp 3 is eight.

[0063] The cross-sectional area of the two second flow resistance plates 22 is 73.0mm 2 ;

[0064] The cross-sectional area of the third flow resistance plate 23 is 133.6mm 2 .

[0065] In summary, we can know that:

[0066] The ratio of the first flow resistance plate 21 to the cross-section of the containing cavity 13 is 7.33%;

[0067] The ratio of the first flow resistance plate 21 to the cross-section of the containing cavity 13 is 13.22%;

[0068] The ratio of the first flow resistance plate 21 to the cross-section of the containing cavity 13 is 24.20%.

Figures 10 to 15 It can be seen that the water flow rate in the disinfection device 100 of Comparative Example 1 is relatively fast as a whole, and the torrent flow rate is also relatively fast.

[0070] Through the above test results, it is shown that the flow resistance device 2 can effectively reduce the water flow rate and the torrent flow rate in the disinfection device 100, and when the flow resistance device 2 is provided with the first flow resistance plate 21, the second flow resistance plate 22 and the third flow resistance plate 23, the flow resistance device 2 has the best effect of reducing the water flow rate and the torrent flow rate.
