Description
Technical Field
[0001] The utility model relates to the technical field of fresh air deodorization for mobile toilets, in particular to a fresh air deodorization and sterilization machine for mobile toilets. Background Art
[0002] Mobile toilets are named for their mobility. They are the opposite of traditional fixed toilets. Compared with traditional toilets, they have obvious advantages. Mobile toilets are not restricted by any working environment, have a light structure, and reasonable color matching. During the use of mobile toilets, fresh air deodorization and sterilization machines are required to deodorize and sterilize them.
[0003] The fresh air deodorizing and sterilizing machines in the prior art usually require manual operation of the machine working mode parameters, are not intelligent enough, and have certain defects in the design of the air duct outlet. For example, if there is no check valve at the outlet, the odor will flow back into the space, which is not good for health; secondly, the air inlets of many equipment have certain restrictions on the physical dust removal and sterilization methods of the air. One air inlet is equipped with one air outlet. The number of air inlets directly affects the efficiency of the equipment. One air inlet can only deal with the air quality problems in this area, and cannot meet the deodorizing and sterilizing functions in multiple areas. The use efficiency is not high, and there are certain cumbersomeness and limitations in the convenience of maintenance. For example, when some machines open the cover of the machine to replace or clean the filter, components, the operation is more complicated, and there are shortcomings in the convenience of maintenance or maintenance. Therefore, we propose a fresh air deodorizing and sterilizing machine for mobile toilets. Utility Model Content

[0033] It can be understood that the utility model can apply negative pressure at one end of the machine to realize air convection circulation through the setting of the fan module 11, which can deodorize, sterilize and purify the toilet air to improve the air cleanliness rate. The primary filter 5, the medium-efficiency filter 6, and the plasma catalytic network 7 are all placed inside the outer door panel 4. You only need to open the buckle on the outer door panel 4 and turn the outer door panel 4 upward to easily clean and replace the filter. The high-energy ion box 15 is directly behind the inner firmware 9. Use a screwdriver to unscrew the screws of the inner firmware 9 and slide out the high-energy ion box 15. The high-energy ion tube 8 inside the high-energy ion box 15 is stuck in the middle under the action of the pre-tightening force of the spring 13. Press the spring 13 to one side with force to remove the high-energy ion tube 8 for cleaning, which is convenient and efficient.
[0034] Furthermore, the number of the air inlets 1 is three, the number of the air outlet 2 is one, and a check valve is provided inside the air outlet 2.
[0035] It can be understood that the utility model facilitates air convection circulation by setting the air inlet 1 and the air outlet 2, and the backflow of exhaust gas in the pipeline can be prevented by setting the check valve.
[0036] Furthermore, the outer side of the housing 10 is symmetrically fixedly connected with a lifting lug 3 .
[0037] It can be understood that the utility model facilitates the installation of the device through the provision of the lifting lug 3 .
[0038] Furthermore, the number of the primary filter screens 5 and the number of the secondary filter screens 6 are both one, and the number of the plasma catalytic screens 7 is three.
[0039] It can be understood that the utility model facilitates the deodorization and sterilization of air by disposing the primary filter 5, the medium filter 6 and the plasma catalytic network 7.
[0040] Furthermore, the fan module 11 includes a fan fixing plate 21 , the fan fixing plate 21 is fixedly connected to the inner wall of the housing 10 , and the fan 20 is installed on the outer side of the fan fixing plate 21 .
[0041] It is understandable that the utility model facilitates the application of negative pressure through the provision of the fan 20 to achieve air convection circulation, thereby deodorizing, sterilizing and purifying the toilet air.
[0042] Furthermore, the inner wall of the shell 10 is provided with PU cotton.
[0043] It is understandable that the utility model can protect the high-energy ion box 15 by providing the PU cotton.
[0044] Specifically, when in use, the whole machine has a rectangular structure, and the direction of wind flow from left to right are three air inlets 1 and air outlets 2, which can act on multiple spaces. Organized exhaust is designed in the space to keep the toilet in a state of slight negative pressure to prevent the air in the toilet from entering the space outside the toilet. Different air volumes are used according to different toilet usage conditions to achieve the effect of rapid deodorization and energy saving. It has an RS-485 communication interface, which can be linked with the mobile toilet intelligent control system to realize intelligent adjustment of air volume. It also has a dry contact I / O interface to connect various sensors of the mobile toilet to realize intelligent adjustment of air volume. When no one goes to the toilet for a long time, it runs at a low air volume, mainly to keep all toilets in standby state for slow ventilation and deodorization, as well as the leakage of odor from fermented sewage in the sewage collection box; when someone goes to the toilet, rapid ventilation is required, and it runs at a medium air volume; when the toilet is finished, the toilet will enter a rapid ventilation state, at which time it works at a high air volume, and the turbid air passes through the primary filter 5. The medium-efficiency filter 6 comes to the high-energy ion box 15. Under the action of the high-energy ion tube 8, odor molecules such as methyl mercaptan, ammonia, and hydrogen sulfide in the air undergo chemical reactions to produce water and other non-toxic and odorless molecules. The toxic volatile organic matter opens its chemical bonds through high-energy ions and becomes stable and harmless small molecules such as carbon dioxide and water after a series of reactions, thereby degrading the organic matter. In addition, the high-energy ion tube 8 ionizes the air to produce ozone. When the ozone passes through the three-layer plasma catalytic net 7, it becomes oxygen and oxygen ions under the action of the catalyst. These oxygen atoms have extremely strong oxidizing properties and can react with organic matter to form non-toxic small molecules such as carbon dioxide and water. At the same time, the organic free radicals generated in the reaction can continue to participate in the chain reaction, further undergo redox reactions, and accelerate the degradation of organic matter. The cell membranes of microorganisms such as bacteria, fungi, viruses, and molds are destroyed under the oxidation of oxygen ions, thereby losing their activity and reproductive ability. Finally, clean air comes out from the air outlet 2, which is convenient to use.
[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
