Detailed implementation manners

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model will be further described below with reference to the embodiments.

[0022] Embodiment: Refer to Figures 1 to 3 , a malodorous gas deodorizing device, including a box body 1, an intake pipe 11 is communicated with one side of the box body 1, an outlet pipe 12 is communicated with the other side of the box body 1, a mounting groove 13 is opened on one side of the box body 1, and a plurality of filtering components are closely arranged inside the mounting groove 13;

[0023] It further includes two irregularly shaped cavities 2 symmetrically opened on one inner wall of the mounting groove 13 with respect to the filtering components. Two first springs 21 are fixedly installed on one inner wall of the cavity 2. The other ends of the two first springs 21 are jointly fixedly installed with a rack 22. The other end of the rack 22 is fixedly installed with a push plate 23. The rack 22 and the push plate 23 are both slidably connected to the cavity 2. A rotating shaft 24 is rotatably connected inside the box body 1 and below the rack 22. A half gear 25 meshing with the rack 22 is fixedly installed at a corresponding position outside the rotating shaft 24. During the use of this device, since the malodorous gas enters the inside of the box body 1 through the intake pipe 11, the filtering components close to the intake pipe 11 first adsorb the organic substances in the malodorous gas and have the largest adsorption content. The adsorption content of the remaining filtering components gradually decreases from the intake pipe 11 towards the outlet pipe 12. Therefore, after using for a period of time, the adsorption capacity of the filtering components close to the intake pipe 11 will saturate first. At this time, it is necessary to disassemble and replace them with new filtering components;

[0024] After the filter assembly is disassembled, the staff rotates the rotating shaft 24 clockwise to drive the two outer half gears 25 to rotate simultaneously, and the half gear 25 meshes with the rack 22 during the rotation, so that the push plate 23 at one end of the rack 22 pushes multiple filter assemblies to move in the direction of the air inlet pipe 11, thereby changing the position of the remaining filter assemblies so that they gradually increase from the air outlet pipe 12 to the air inlet pipe 11. At the same time, due to the incomplete teeth on the outer side of the half gear 25, when the half gear 25 is no longer meshed with the rack 22, the rack 22 is reset by the pulling force of the two springs 21, so that the push plate 23 at one end is retracted into the cavity 2 again. At this time, the new filter assembly can be directly inserted into the mounting groove 13. Only the filter assembly close to the air inlet pipe 11 needs to be replaced each time, thereby improving the use effect of the equipment.

[0025] The filter assembly includes an activated carbon filter 3, and rubber plates 31 are fixedly installed on both sides of the activated carbon filter 3. The rubber plates 31 are in contact with the opposite side of the mounting groove 13. A handle 32 is fixedly installed on one side of the rubber plate 31 located on the outside. When the gas passes through the activated carbon filter 3, organic matter is adsorbed and stays on the surface of the activated carbon, thereby reducing the concentration of the malodorous gas. At the same time, the rubber plates 31 can prevent gas leakage and improve the sealing performance of the equipment.

[0026] Two grooves 4 are symmetrically provided on one side of the rubber plate 31 about the handle 32, and a spring 2 41 is fixedly installed on the opposite side of the two grooves 4, and a limit block 42 is fixedly installed on the other end of the spring 2 41, and the limit block 42 is slidably connected to the groove 4, and a slide groove 43 slidably connected to the limit block 42 is provided on the inner wall of the installation groove 13 and at the corresponding position of the limit block 42. When the activated carbon filter 3 needs to be replaced, the staff can move the two limit blocks 42 relative to each other so that they are no longer engaged with the slide groove 43, and then pull the handle 32 outward to remove the activated carbon filter 3. When installing the activated carbon filter 3, the rebound force of the spring 2 41 pushes the two limit blocks 42 to move away from each other, and the limit block 42 is inserted into the slide groove 43, so that the limit block 42 can be limited and fixed.

[0027] Two limiting rods 5 are symmetrically fixedly installed on one side of the push plate 23, and a limiting groove 51 slidably connected to the limiting rod 5 is opened on the inner wall of one side of the cavity 2 at a corresponding position of the limiting rod 5 to limit the position of the push plate 23 and ensure that the push plate 23 maintains horizontal movement.

[0028] One end of the air inlet pipe 11 is connected to a gas distributor 6, and one end of the air outlet pipe 12 is connected to a gas collecting hood 61. The malodorous gas is dispersed into the interior of the box body 1 through the gas distributor 6, thereby improving the filtering effect of the malodorous gas.

[0029] A plurality of ultraviolet lamps 7 are fixedly mounted on the inner wall of the gas collecting hood 61, and a controller 71 for controlling the switch of the ultraviolet lamp 7 is fixedly mounted on the outer side of the box body 1. The controller 71 controls the operation of the ultraviolet lamp 7 so that the filtered gas is irradiated by the controller 71, thereby producing ozone and other active oxygen species, which have strong oxidizing properties and can decompose and remove organic compounds in the gas.

[0030] The working principle of the utility model is as follows: when the device is in use, since the malodorous gas enters the interior of the box body 1 through the air inlet pipe 11, the filter component close to the air inlet pipe 11 first adsorbs the organic matter in the malodorous gas, and the adsorption content is the largest, and the adsorption content of the organic matter of the remaining filter components gradually decreases from the air inlet pipe 11 toward the air outlet pipe 12. Therefore, after a period of use, the adsorption capacity of the filter component close to the air inlet pipe 11 will be saturated first, and it needs to be disassembled and replaced with a new filter component at this time;

[0031] When the two stop blocks 42 are no longer engaged with the slide groove 43, the staff member pushes the two limit blocks 42 to move relative to each other, so that they are no longer engaged with the slide groove 43, and then pulls the handle 32 outward to remove the activated carbon filter 3. Then the staff member rotates the rotating shaft 24 clockwise to drive the two outer half gears 25 to rotate simultaneously, and the half gear 25 meshes with the rack 22 during the rotation process, so that the push plate 23 at one end of the rack 22 pushes the remaining filter components to move toward the direction of the intake pipe 11, thereby changing the position of the remaining filter components, so that it increases step by step from the outlet pipe 12 to the direction of the intake pipe 11, and because the teeth on the outer side of the half gear 25 are incomplete, when the half gear 25 is no longer engaged with the rack 22, the rack 22 is reset by the pulling force of the two springs 1 21, so that the push plate 23 at one end retracts into the interior of the cavity 2 again, and the new filter component can be directly inserted into the installation groove 13 at this time. Only the filter component close to the intake pipe 11 needs to be replaced each time, which prevents the staff from misremembering the position of the filter component to be replaced and improves the use effect of the equipment.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
