Description

Technical Field

[0001] This application relates to the field of outdoor temporary toilet technology, and in particular to a temporary toilet with built-in deodorization and sterilization functions. Background Technology

[0002] With the rapid development of cultural tourism, temporary large-scale events are becoming increasingly frequent, such as music festivals and marathons. These events typically attract large crowds and are characterized by their temporary and concentrated nature. This gathering of people also leads to increased physiological needs. Existing public restrooms cannot meet the surge in participants, but building a fully equipped, permanent, large-scale restroom is not cost-effective. Therefore, temporary portable toilets have emerged as a solution.

[0003] Temporary toilets offer advantages such as high mobility, low cost, short service life, and rapid installation and dismantling, allowing for flexible deployment according to event needs. However, due to their simple construction, temporary toilets often lack certain functions, such as limited internal space, low water capacity, darkness, and poor ventilation. In particular, poor ventilation and the concentrated arrangement of temporary toilets can lead to high odor concentrations on-site, often noticeable even from outside the toilet area.

[0004] The following are common deodorizing and sterilizing devices used in toilets in the prior art, and their limitations:

[0005] 1. Physical methods can be broadly divided into two types. The first type is dilution and diffusion, which involves using ventilation and exhaust methods to extract indoor air and release it into the atmosphere, thereby reducing the concentration of indoor odors.

[0006] The second method is adsorption, which uses adsorption materials such as activated carbon to adsorb odor components in the exhaust gas.

[0007] However, the basic principle of physical methods is odor transfer, where the odor spreads from indoors to outdoors. The higher odor intensity outdoors causes a localized accumulation of odor. Adsorbents are easily saturated, and if they are not replaced in time, they will lose their deodorizing effect, or the replaced adsorbents will be difficult to dispose of.

[0008] 2. The chemical method is a chemical reaction method, which involves spraying chemical components that can react with odor molecules or pathogens into the odor, such as sodium hypochlorite.

[0009] Although this method has some oxidizing properties, it is ineffective for components that are poorly water-soluble, and the chemical reagent residue can easily generate toxic components such as chlorine gas. If the concentration used is too high or the residue is not dissipated in time, it will affect the next use.

[0010] 3. The biological method is the microbial degradation method, which uses microorganisms to degrade odor molecules.

[0011] The disadvantages are that the environmental conditions for microorganisms to live in are harsh, requiring specific temperature, humidity and pH values, and the microorganisms have a narrow range of applicability to odor components, slow metabolism, and insignificant deodorization effect.

[0012] Other methods include using stronger fragrances to mask odors, but this method does not actually eliminate odor molecules and only achieves the masking effect; and using ultraviolet lamps for disinfection, but in actual use, ultraviolet lamps are prone to damage, increasing maintenance costs, etc. Utility Model Content

[0013] The purpose of this application is to overcome the problem of high odor concentration inside and around temporary toilets in the prior art, and to provide a temporary toilet with deodorization and sterilization functions.

[0014] Specifically, the temporary toilet with built-in deodorization and sterilization function includes a first box with a door, a first cavity and a second cavity reserved in the first box, toilet furniture in the first cavity, and a fan and a pulse discharge device in the second cavity. The air inlet of the pulse discharge device is connected to the first cavity, and the air outlet of the pulse discharge device is connected to the fan.

[0015] In some possible implementations, an electrical control box is also included, which houses a controller and a human-machine interface device. The fan, pulse discharge device, and human-machine interface device are all electrically connected to the controller. A gas sensor for detecting hydrogen sulfide and / or ammonia is installed at the outlet of the fan, enabling the fan and pulse discharge device to operate intelligently and automatically. Based on the composition and content of the outlet gas detected by the gas sensor, the output power is automatically adjusted to ensure the odor treatment effect.

[0016] In some possible implementations, the controller is also electrically connected to a power interface, enabling the temporary toilet of this application to be powered by an external power source.

[0017] In some possible implementations, the controller is also electrically connected to a rechargeable power source, enabling the temporary toilet of this application to be powered by its own rechargeable power source.

[0018] In some possible implementations, a third cavity is reserved inside the first chamber, located between the first and second cavities. A first air pipe is installed in the third cavity, and a first air collection port is installed at one end of the first cavity. The air inlet of the pulse discharge device is connected to the first cavity through the first air pipe and the first air collection port, allowing the temporary toilet of this application to connect to multiple toilets. One temporary toilet with a second cavity, a fan, and a pulse discharge device can be used as the main unit for deodorization. Existing toilets without deodorization devices only need to have an air outlet added to connect to the pulse discharge device of the main unit through the first air pipe to achieve joint deodorization and sterilization. This is suitable not only for the manufacture of new toilets but also for the renovation of old toilets. Only one toilet in a group needs to be connected to an external power source to act as the main unit.

[0019] In some possible implementations, the first air tube is open at both ends and connected to the first air collection port in the middle. A removable sealing plug is installed at the end of the first air tube away from the pulse discharge device. When it is not necessary to connect to other toilets, the sealing plug can be used to seal one end of the first air tube, so that the fan and pulse discharge device can treat the odor in the first cavity more efficiently. When it is necessary to connect to other toilets that do not have active deodorization capabilities, the sealing plug can be removed and connected to other toilets that do not have active deodorization capabilities.

[0020] In some possible implementations, a second enclosure with a door is also included. The second enclosure has a fourth chamber and a fifth chamber. The fourth chamber contains a toilet, and the fifth chamber contains a second air pipe. A second air collection port is installed at one end of the fourth chamber. The second air pipe is connected to the second air collection port, and one end of the second air pipe is connected to the first air pipe. With the first enclosure as the main unit and the second enclosure as the auxiliary unit, multiple auxiliary units can be connected to one main unit to achieve deodorization. Only one main unit with a fan and a pulse discharge device is required.

[0021] In some possible implementations, the door is fitted with an air intake grille, which allows fresh air to be continuously replenished inside the temporary toilet, preventing oxygen deficiency.

[0022] This application has the following beneficial effects: The temporary toilet of this application has a wide range of applications and a high degree of integration. It can achieve deodorization of the toilet itself, and has good deodorization and disinfection effects without secondary pollution. It adopts a pulsed electric deodorization device, which does not produce waste such as activated carbon, does not require the preparation of chemical deodorizing agents, and only uses clean energy electricity, without secondary pollution.

[0034] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0035] Please see Figures 1-3 In a preferred embodiment of this application, a temporary toilet with built-in deodorization and sterilization functions includes a first box 1 with a door 2. The first box 1 is a prefabricated structure and can be made of materials such as plastic, metal, or reinforced concrete. To avoid electric shock, the first box 1 is preferably made of a non-conductive material. If the first box 1 is made of a conductive material, the outer wall is sprayed with insulating paint to prevent accidental leakage of electrical equipment such as the fan 6 and the pulse discharge device 7 from injuring the user. The first box 1 has a first cavity 3 and a second cavity 4. The first cavity 3 is equipped with toilet fixtures 5, including a toilet seat or squat toilet, a flushing device, and a sludge collection box. The second cavity 4 is equipped with a fan 6 and a pulse discharge device 7. The air inlet of the pulse discharge device 7 is connected to the first cavity 3, and the air outlet of the pulse discharge device 7 is connected to the fan 6. The fan 6 is responsible for providing the power to extract odor. The odor is purified by electrode pulse discharge in the pulse discharge device 7.

[0036] To adapt to more application scenarios, such as in areas without municipal sewage pipes, more water-saving vacuum collection devices can be used to collect feces and sewage, reducing the frequency of cleaning due to a full collection tank. Unrestricted by terrain or drainage facilities, they can be quickly set up and put into use, solving the problem of difficult sewage discharge.

[0037] To achieve automated control of the temporary toilets, an electrical control box 8 is also included, such as... Figure 4 As shown, the electrical control box 8 contains a controller 9 and a human-machine interface device 10. The human-machine interface device 10 can be a button, a display screen, or a touch screen, etc. Figure 7As shown, the fan 6, pulse discharge device 7, and human-machine interface device 10 are all electrically connected to the controller 9. The outlet of the fan 6 is equipped with a gas sensor 11 for detecting hydrogen sulfide and / or ammonia. It should be noted that the gas sensor 11 can be one, two, or more, such as Figaro (TGS 825), Membrapor (H2S / S-100), Membrapor (NH3 / S-100), etc., so that the fan 6 and pulse discharge device 7 can operate intelligently and automatically. According to the composition and content of the outlet gas detected by the gas sensor 11, the output power is automatically adjusted to ensure the treatment effect of odor. If the concentration of hydrogen sulfide or ammonia at the outlet is too high, the power of the deodorization device is increased to enhance the electric field strength and eliminate odor.

[0038] In order to provide power to the temporary toilet, the controller 9 is also electrically connected to the power interface 12, so that the temporary toilet of this application can be powered by an external power source using the power interface 12.

[0039] To adapt to outdoor environments without mains power, the controller 9 is also electrically connected to a rechargeable power supply 13, enabling the temporary toilet of this application to be powered by its own rechargeable power supply 13.

[0040] like Figure 2 As shown, a third chamber 14 is reserved inside the first housing 1. The third chamber 14 is located between the first chamber 3 and the second chamber 4. A first air pipe 15 is installed inside the third chamber 14. A first air collection port 16 is installed at one end of the first chamber 3. The air inlet of the pulse discharge device 7 is connected to the first chamber 3 through the first air pipe 15 and the first air collection port 16, so that the temporary toilet of this application can connect to multiple toilets. One temporary toilet with a second chamber 4, a fan 6 and a pulse discharge device 7 can be used as the main unit for deodorization. Existing toilets without deodorization devices only need to add an air outlet, which can be connected to the pulse discharge device 7 of the main unit through the first air pipe 15 to achieve joint deodorization and sterilization. It is not only suitable for the manufacture of new toilets, but also for the renovation of old toilets. Only one toilet in a group needs to be connected to an external power source as the main unit.

[0041] To facilitate connection to other toilets without deodorization functions, the first air pipe 15 is open at both ends and connected to the first air collection port 16 in the middle. A removable sealing plug 17 is installed at the end of the first air pipe 15 away from the pulse discharge device 7. When it is not necessary to connect to other toilets, the sealing plug 17 can be used to seal one end of the first air pipe 15, so that the fan 6 and the pulse discharge device 7 can treat the odor in the first cavity 3 more efficiently. When it is necessary to connect to other toilets without active deodorization capabilities, the sealing plug 17 can be removed and the first air pipe 15 can be used to connect to other toilets without active deodorization capabilities. A fan 6 can then draw the odor from this temporary toilet and other toilets connected to the first air pipe 15 into the pulse discharge device 7 for purification and deodorization.

[0042] like Figure 5 and Figure 6 As shown, it also includes a second box 18 with a door 2. The second box 18 has a fourth cavity 19 and a fifth cavity 20 reserved inside. The fourth cavity 19 is equipped with a toilet 5, which is the same as the toilet 5 in the first box 1. The toilet 5 includes a toilet or squat toilet, a flushing device, and a sludge collection tank, etc. The fifth cavity 20 is equipped with a second air pipe 21. A second air collection port 22 is installed at one end of the fourth cavity 19. The second air pipe 21 is connected to the second air collection port 22. One end of the second air pipe 21 is connected to the first air pipe. Similarly, the second air pipe 21 is also open at both ends and has a removable sealing plug 17 at both ends. The sealing plug 17 can be removed as needed. With the first box 1 as the main unit and the second box 18 as the auxiliary unit, multiple auxiliary units can be connected to one main unit to achieve deodorization. Only one main unit with a fan 6 and a pulse discharge device 7 is required. All the odor in the main unit and auxiliary units is collected and transmitted through the first air pipe 15 and the second air pipe 21.

[0043] Specifically, the odor from multiple toilets, drawn by the fan 6, enters the pulse discharge device 7. As the odor passes through the high-energy electric field inside the pulse discharge device 7, the odor molecules undergo inelastic collisions with high-energy electrons, achieving bond breaking and recombination of the odor molecules, thus deodorizing in a short time.

[0044] The airflow of fan 6 can be adjusted according to deodorization needs and the number of toilets connected. The airflow of fan 6 is adjustable, ranging from 50 to 500 m³ / h. 3 / h. Two buttons are set on the electrical control box 8 as part of the human-machine interaction device 10, which are divided into low wind and high wind. The toilet maintenance personnel can select different air volume according to the actual situation. The larger the air volume, the higher the air exchange rate and the better the deodorization ability.

[0045] The pulse discharge device 7 is equipped with a pulse power supply and an electric field. When an external power source is connected, the pulse power supply discharges the electric field to achieve deodorization.

[0046] The outlet of the blower 6 is equipped with a gas sensor 11 as an online detector to detect the concentration of hydrogen sulfide and ammonia. The detection signal is transmitted to the controller 9 in the electrical control box 8 in real time. If one of the components exceeds the limit, the controller 9 issues a command to increase the output power of the pulse power supply in the pulse discharge device 7, increase the electric field strength, and enhance the deodorization efficiency to achieve intelligent automatic operation.

[0047] To filter large particles and live small animals, removable filters are installed in both the first air collection port 16 and the second air collection port 22. These filters remove large particles and live small animals from the odorous air, preventing them from entering and clogging pipes or damaging equipment. A removable filter is also installed at the air outlet of the fan 6, which can be removed and cleaned if clogged.

[0048] To ensure air intake in the toilet, the door 2 is equipped with an air intake grille 23, which allows fresh air to be continuously replenished inside the temporary toilet, preventing oxygen deficiency. At the same time, the air intake is decentralized, with no noticeable wind, reducing user discomfort.

[0049] This embodiment of the temporary toilet has a wide range of applications and a high degree of integration. It can deodorize the toilet itself or connect multiple toilets to use a single main unit for deodorization. Existing toilets without deodorization devices only need to have an air outlet added to connect to the main unit for joint deodorization and sterilization. It is suitable not only for the manufacture of new toilets but also for the renovation of old toilets. Only one unit in a set of devices needs to be connected to an external power source, and it has good deodorization and disinfection effects without secondary pollution. It adopts a pulsed electric deodorization device, which does not produce waste such as activated carbon, does not require the preparation of chemical deodorizing agents, and only uses clean energy electricity, resulting in no secondary pollution.

[0050] The above are merely preferred embodiments of this application; however, the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and its improved concept, should be covered within the scope of protection of this application.
