[0002] The existing negative pressure ozone generator has a negative pressure fan in its body, and a vent corresponding to the negative pressure fan is provided on the body, so that air is introduced into the body through the vent. After long-term operation, the isolation net of the vent is easy to be stained with a lot of dust, which will affect the operation of the equipment if it is not cleaned in time. However, the existing technology generally uses disassembly to clean the isolation net, which is very inconvenient. Summary of the invention

[0004] The utility model includes a shell, which is provided with an air inlet, and an isolation net is installed on the air inlet. Longitudinal strips are respectively fixed on both sides of the isolation net, and opposite longitudinal long grooves are arranged on the two strips. Both ends of a transversely arranged cleaning plate cooperate with the longitudinal long grooves. A groove along the length direction of the cleaning plate is arranged on the side of the isolation net, and a group of springs are arranged in the groove. A brush plate with a brush is installed between the spring and the isolation net, and the brush can contact the isolation net; the two ends of the spring are respectively fixedly connected with the brush plate and the cleaning plate.

[0005] Furthermore, two guide shafts perpendicular to the cleaning plate are fixed on the surface of the brush plate adjacent to the cleaning plate. The guide shafts pass outward through the guide holes on the cleaning plate, and the outer ends of the guide shafts have retaining rings larger than the diameter of the guide holes.

[0006] Furthermore, the upper and lower parts of the surface of the brush plate facing the isolation net are inclined surfaces.

[0007] Furthermore, a handle is provided on the cleaning plate.

[0008] Furthermore, a cylinder is fixed on the outer shell above the cleaning plate, a piston rod of the cylinder is connected to the middle part of the U-shaped rod, and two side rods of the U-shaped rod are respectively connected to the left and right parts of the cleaning plate.

[0009] The cleaning plate arranged at the front end of the air inlet of the utility model can disturb and clean the isolation net through the action force of the brush and the spring, so as to quickly remove the dust attached to the isolation net, and the cleaning operation is simple and convenient.

[0017] by Figure 1 The up, down, left, right, front and back directions of the illustrated embodiment are defined. Embodiment 1:

[0018] As shown in the figure, this embodiment includes a housing 1, and an air inlet 2 is provided at the front end of the housing 1, and the air inlet 2 is used to ventilate and dissipate heat inside the housing 1. An isolation net 3 is provided at the front end of the air inlet 2, which can block dust in the air during the air intake process and play a certain dust-proof role.

[0019] The isolation net 3 is symmetrically provided with strips 4 on the left and right sides, and the strips 4 are placed longitudinally and fixedly connected to the housing 1. The two strips 4 are longitudinally provided with opposite long grooves, and a cleaning plate 5 is provided between the two strips 4. The left and right ends of the cleaning plate 5 are connected with the long grooves of the strips 4 and can slide up and down along the long grooves. The cleaning plate is provided with a groove on the side facing the isolation net, and a group of springs 6 are provided in the groove. In this embodiment, the spring 6 is composed of three springs uniformly distributed along the groove. A brush plate 7 is fixedly connected to the rear end of the spring 6, and a brush 8 is provided at the rear end of the brush plate 7. The brush 8 can contact the isolation net 3 to clean dust. During the cleaning process, the brush 8 will continuously squeeze the spring 6 through the brush plate 7, and the dust attached to the isolation net 3 is disturbed and cleaned through the reaction force of the spring 6, thereby improving the cleaning effect of the brush 8. Guide shafts 9 are provided on the left and right sides of the front end of the brush plate 7, and guide holes are provided at the corresponding positions of the cleaning plate 5. The guide shaft 9 is slidably connected to the cleaning plate 5 through the guide holes. The rear end of the guide shaft 9 is fixedly connected to the brush plate 7, and the front end is provided with a retaining ring with a diameter larger than the diameter of the guide hole to prevent the guide shaft 9 from coming out. During the cleaning process, the guide shaft 9 can guide and limit the forward and backward sliding of the brush plate 7, thereby improving the stability of the brush plate 7.

[0020] In this embodiment, the upper and lower rear sides of the brush plate 7 are inclined, which can flexibly contact the isolation net 3 during the up and down sliding of the brush plate 7 to prevent damage caused by collision.

[0021] The upper end of the cleaning plate 7 is provided with a cylinder 10, which is fixedly connected to the housing 1. The lower end of the piston rod of the cylinder 10 is provided with a U-shaped rod 11, which is fixedly connected to the middle position of the piston rod and the U-shaped rod 11, and the lower end of the U-shaped rod 11 is fixedly connected to the cleaning plate 5, and the two side rods are respectively connected to the left and right parts of the cleaning plate 5, which can ensure that the cleaning plate 5 is evenly stressed on the left and right sides. When in use, the cylinder 10 can be controlled to push the cleaning plate 5 through the U-shaped rod 11, so that the cleaning plate 5 moves up and down.

[0022] When the utility model is in use, the cylinder 10 is first started, and the cleaning plate 5 is pushed down along the strip plate 4 by the U-shaped rod 11. After the brush 8 contacts the isolation net 3, the spring 6 is squeezed by force, and the isolation net 3 is disturbed and cleaned by the reaction force of the spring 6. The brush plate 7 ensures its own stability through the guide shaft 7 before and after being subjected to the force. After the isolation net is cleaned, the control cylinder resets the cleaning plate to complete the cleaning work. Embodiment 2:

[0023] As shown in the figure, this embodiment includes a housing 1, an air inlet 2 is provided at the front end of the housing 1, and an isolation net 3 is provided at the front end of the air inlet 2. Strips 4 are symmetrically provided on the left and right sides of the isolation net 3, and the strips 4 are placed longitudinally and fixedly connected to the housing 1. The two strips 4 are provided with long grooves on the side facing the isolation net, and a cleaning plate 5 is provided between the two strips 4. The structure of the brush plate part provided on the rear side of the cleaning plate 5 is the same as that of the embodiment 1, and will not be repeated here.

[0024] Different from the first embodiment, the present embodiment does not have a cylinder structure, but a handle 12 is provided on the upper end of the cleaning plate 5. When in use, the isolation net 3 is cleaned by manually pulling the handle 12 upwards, and the cleaning plate 5 is lowered and reset after the cleaning is completed.

[0025] When the utility model is in use, a negative pressure ozone generator that needs to clean more dust can adopt the technical solution of embodiment 1, and a negative pressure ozone generator that needs to clean less dust can adopt the technical solution of embodiment 2.
