[0033] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0034] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are orientations or positional relationships based on the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0036] The terms "first", "second" and "third" (if any) in the specification and claims of this application and the above drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0037] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or display comprising a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or display.

[0038] In the prior art, domestic waste is generally discharged into the sewage pipe by water flushing, and then flows to the septic tank for decomposition. However, the above method consumes a lot of water resources, and it is inconvenient to treat domestic waste in places or areas where water supply is difficult. If the domestic waste is not treated, it will pollute the environment.

[0039] After repeated thinking and verification, the inventors found that if biodegradation technology is used to decompose domestic waste in a centralized manner, reliable treatment of domestic waste can be achieved, environmental pollution caused by domestic waste can be avoided, and water resources can be saved at the same time. By setting up a domestic waste treatment device, domestic waste can fully react with the auxiliary material package (including reaction medium and complex enzyme) in the treatment device, and the water generated by the reaction of domestic waste can be discharged from the treatment device after forming water vapor, thus achieving clean and environmental protection.

[0040] In view of this, the inventor has designed a domestic waste treatment device, which contains domestic waste and auxiliary material bags through a reaction chamber, fully mixes domestic waste and auxiliary material bags through a stirring component, provides a suitable temperature for the reaction of domestic waste and auxiliary material bags through a heating component, and at the same time, the heating component can also make the water generated by the reaction form water vapor, and exhaust the water vapor inside the reaction chamber through an exhaust component. In this way, reliable treatment of domestic waste can be achieved in places or areas where water supply is difficult, avoiding domestic waste from polluting the environment.

[0041] The technical solution of the domestic waste treatment device provided in the embodiment of the present application is described in detail below in conjunction with the accompanying drawings.

[0042] Reference Figure 1-Figure 4 The domestic waste treatment device provided in the embodiment of the present application includes a reaction chamber 100, a stirring assembly 200, a heating assembly 300 and an exhaust assembly 400. The reaction chamber 100 is provided with a containing chamber 110, and the containing chamber 110 is configured to contain domestic waste and an auxiliary material bag 600. The top of the reaction chamber 100 is provided with an opening 120 connected to the containing chamber 110. The stirring assembly 200 is installed on the reaction chamber 100, and the stirring assembly 200 is configured to stir the internal substances of the reaction chamber 100. The heating assembly 300 is installed on the reaction chamber 100, and the heating assembly 300 is configured to heat the internal substances of the reaction chamber 100. The exhaust assembly 400 is installed on the reaction chamber 100, and the exhaust assembly 400 is configured to exhaust the internal gas of the reaction chamber 100.

[0043] Exemplarily, the reaction chamber 100 may be a semi-enclosed barrel structure, which serves as the core of the domestic waste treatment device, and the domestic waste and the added auxiliary material package 600 may react inside the reaction chamber 100. The domestic waste and the auxiliary material package 600 may enter the containing chamber 110 from the opening 120 at the top of the reaction chamber 100. The shape of the reaction chamber 100 in this embodiment is only exemplary, and those skilled in the art may set the shape of the reaction chamber 100 according to the use scenario of the domestic waste treatment device to improve the practicality of the domestic waste treatment device, and no sole limitation is made here.

[0044] It is worth mentioning that the auxiliary material package 600 is a granular material, which provides a reaction carrier. The auxiliary material package 600 includes a reaction medium and a complex enzyme involved in biodegradation. The reaction medium can be a mixture of coconut bran or rice husk and poplar wood chips. During the operation of the domestic waste treatment device, the auxiliary material package 600 is added to the reaction chamber 100, and the auxiliary material package 600 provides a reaction space for biodegradation.

[0045] Figure 1-Figure 4It is shown that the stirring assembly 200 is installed at the lower part of the reaction bin 100 to ensure that the stirring assembly 200 can fully stir the substances inside the reaction bin 100, namely, the domestic waste and the auxiliary material bag 600. The heating assembly 300 can be installed at the bottom of the reaction bin 100 to provide heat for the reaction bin 100, thereby providing a suitable temperature for biodegradation. Among them, the auxiliary material bag 600 can decompose the domestic waste into salts and water, and the heat provided by the heating assembly 300 can evaporate the water formed after the decomposition of the domestic waste into water vapor. The user only needs to clean the containing chamber 110 of the reaction bin 100 regularly to remove the salts formed after the decomposition of the domestic waste.

[0046] In one possible implementation, the exhaust assembly 400 can be installed at the upper rear of the reaction chamber 100. The exhaust assembly 400 can exhaust the water vapor inside the reaction chamber 100 to the outdoors to prevent the odor of the water vapor inside the reaction chamber 100 from affecting the user.

[0047] Exemplarily, the domestic waste treatment device is provided with a switch to control the operation of the stirring component 200, the heating component 300 and the exhaust component 400. The domestic waste treatment device can be installed in places such as RVs and civil toilets according to actual use scenarios. When the domestic waste treatment device is used, the auxiliary material package 600 is added to the reaction chamber 100, the power is turned on, and the switch is turned on to control the degradation of domestic waste within a period of time.

[0048] The domestic waste treatment device provided in this embodiment has the functions of automatic stirring, heating and exhausting. Domestic waste can enter the containing chamber 110 from the opening 120 of the reaction chamber 100. The user can add the auxiliary material package 600 into the containing chamber 110 through the opening 120. The auxiliary material package 600 and the domestic waste are fully mixed under the stirring of the stirring component 200. The heating component 300 heats the reaction chamber 100 to provide a suitable temperature for the domestic waste and the auxiliary material package 600 in the containing chamber 110, so that the reaction medium and the complex enzyme in the auxiliary material package 600 can fully react with the domestic waste. Through biodegradation technology, the domestic waste is decomposed into water and salts. The water formed after the degradation of the domestic waste evaporates into water vapor under the action of the heating component 300 and is discharged to the outdoors through the exhaust component 400, which is clean and environmentally friendly. In this way, domestic sewage can be reliably treated in places and areas where water supply is difficult, avoiding domestic sewage from polluting the environment. At the same time, water resources can be saved, solving the problems of difficulty in discharging domestic sewage and wasting water resources, and avoiding the tedious work of deep burying domestic sewage.

[0049] In addition, the domestic waste treatment device provided in this embodiment has the characteristics of small size, low noise, low energy consumption, no odor, low emission and easy placement, and is suitable for RVs, daily life, patient care or other places and areas where water supply is difficult. The domestic waste treatment device can be connected to an energy storage device such as a battery or a new energy power generation device such as a solar power generation device or a wind power generation device, and the energy storage device or the new energy power generation device supplies power to the domestic waste treatment device, which is suitable for places and areas where power supply is difficult. Compared with water flush toilets, it is more environmentally friendly, more energy-saving, and easier to promote and use.

[0050] In one embodiment, Figure 1 , Figure 2 and Figure 4 As shown, the domestic waste treatment device further includes an electric control unit 500, which is installed on the reaction chamber 100, and the electric control unit 500 is electrically connected to the stirring component 200, the heating component 300 and the exhaust component 400 respectively.

[0051] Schematically, the electronic control unit 500 includes a control circuit board and a processor installed on the control circuit board. The control circuit board can be installed on the outer wall of the reaction chamber 100, and the control circuit board can be electrically connected to the stirring component 200, the heating component 300 and the exhaust component 400 through wires, respectively, so that the controller on the control circuit board can control the operation of the stirring component 200, the heating component 300 and the exhaust component 400.

[0052] With this structure, the user can control the operation of the stirring assembly 200, the heating assembly 300 and the exhaust assembly 400 by controlling the electronic control unit 500, which is convenient for the user to operate.

[0053] In a specific embodiment, Figure 1-Figure 4 As shown, the stirring assembly 200 includes a stirring shaft 210 and a motor 220. The stirring shaft 210 is rotatably mounted on the reaction chamber 100. The body of the motor 220 is mounted on the reaction chamber 100. The output shaft of the motor 220 is transmission-connected to the stirring shaft 210. The motor 220 is electrically connected to the electronic control unit 500.

[0054] Optionally, both ends of the stirring shaft 210 are rotatably connected to two opposite side walls of the reaction bin 100, and a stirring blade is provided on the portion of the stirring shaft 210 located in the receiving chamber 110. When the motor 220 drives the stirring shaft 210 to rotate relative to the reaction bin 100, the stirring blade on the stirring shaft 210 can fully stir the domestic waste and the auxiliary material bag 600 in the receiving chamber 110. This embodiment does not limit the specific structure of the stirring blade, and those skilled in the art can set a suitable stirring blade as needed, which is not limited here.

[0055] Exemplarily, the body of the motor 220 can be fixedly mounted on the reaction chamber 100 by fasteners, a mounting hole can be provided at one end of the stirring shaft 210 facing the motor 220, and the output shaft of the motor 220 can extend into the mounting hole on the stirring shaft 210 to drive the stirring shaft 210 to rotate relative to the reaction chamber 100. Optionally, a wire can be used to electrically connect the body of the motor 220 to the electronic control unit 500.

[0056] With this structure, the user can control the motor 220 through the electronic control unit 500 to drive the stirring shaft 210 to rotate, so as to fully stir the domestic waste and the auxiliary material package 600 in the containing chamber 110, so that the auxiliary material package 600 is in full contact with the domestic waste, and then the complex enzyme in the auxiliary material package 600 can fully degrade the domestic waste.

[0057] In a more specific embodiment, Figure 2 As shown, a bearing seat 230 is installed on the side wall of the reaction chamber 100 facing the motor 220, and one end of the stirring shaft 210 is connected to the bearing seat 230 through a bearing.

[0058] Exemplarily, the bearing seat 230 can be mounted on the reaction chamber 100 by fasteners. It can be understood that a bearing is installed in the bearing seat 230, the outer ring of the bearing is fixedly connected to the bearing seat 230, and the end of the stirring shaft 210 facing the motor 220 is arranged through the inner ring of the bearing, and the stirring shaft 210 is fixedly connected to the inner ring of the bearing. In a possible implementation, the body of the motor 220 can be installed on the side of the bearing seat 230 away from the reaction chamber 100. The bearing in the bearing seat 230 allows the stirring shaft 210 to rotate relatively smoothly relative to the reaction chamber 100. In addition, the bearing can also withstand radial loads, which is conducive to improving the bearing capacity of the stirring assembly 200.

[0059] In a more specific embodiment, Figure 1 and Figure 2 As shown, a cover 240 is installed on the side wall of the reaction chamber 100 away from the motor 220. The cover 240 is provided with a blind hole, and one end of the stirring shaft 210 away from the motor 220 extends into the blind hole and is rotatably connected to the blind hole.

[0060] Schematically, a through hole is provided on the side wall of the reaction chamber 100 away from the motor 220, and the cover 240 blocks the through hole on the reaction chamber 100 to prevent the life waste and the auxiliary material package 600 in the receiving chamber 110 from leaking from the through hole. Exemplarily, the cover 240 can be a plastic part, which can be installed on the reaction chamber 100 by fasteners. A shaft body is provided at one end of the stirring shaft 210 away from the motor 220, and the shaft body extends from the through hole of the reaction chamber 100 and then extends into the blind hole on the cover 240.

[0061] In this embodiment, the end of the stirring shaft 210 away from the motor 220 can be limited by the cover body 240. At the same time, the cost of the cover body 240 is lower than that of the bearing, which is conducive to reducing the cost of the domestic waste treatment device.

[0062] like Figure 1-Figure 4 As shown, there are multiple stirring assemblies 200, and the multiple stirring assemblies 200 are arranged side by side.

[0063] There is a gap between the stirring shafts 210 of two adjacent stirring components 200 to avoid interference between the two adjacent stirring shafts 210. The arrangement direction of the plurality of stirring components 200 is perpendicular to the axial direction of the stirring shaft 210. For example, Figure 4 As shown, when the axis of the stirring shaft 210 extends along the length direction of the reaction chamber 100, multiple stirring assemblies 200 can be arranged side by side along the width direction of the reaction chamber 100. This embodiment does not limit the specific number of stirring assemblies 200, such as two, three or four, etc., which is not limited here.

[0064] With this structure, the user can control the multiple stirring components 200 to stir the domestic waste and the auxiliary material package 600 in the containing chamber 110, so that the domestic waste and the auxiliary material package 600 are mixed more fully, so that the complex enzyme in the auxiliary material package 600 can fully degrade the domestic waste.

[0065] like Figure 1 and Figure 3 As shown, in a possible implementation, the heating assembly 300 includes a heating plate 310. The heating plate 310 covers the bottom of the reaction chamber 100, and the heating plate 310 is electrically connected to the electric control unit 500.

[0066] The heating plate 310 can be attached to the bottom of the reaction chamber 100, and can fit tightly with the reaction chamber 100. It can be understood that the heating plate 310 can convert electrical energy into thermal energy when powered on, and its heating power is related to the input current, and its own heating limit can be set according to the use needs. Those skilled in the art can select a heating plate 310 of suitable material and size according to the value of the required heating temperature. For example, Figure 1 and Figure 3 As shown, the heating plate 310 can cover a portion of the bottom wall of the reaction chamber 100 and a portion of the side wall of the reaction chamber 100 close to the bottom.

[0067] In this structure, the electronic control unit 500 can control the heating plate 310 to generate heat, and the heating plate 310 evenly heats the reaction chamber 100, so that the temperature inside the containing chamber 110 is more suitable for the reaction between the domestic waste and the auxiliary material package 600. At the same time, the heating component 300 can reliably heat the water formed after the degradation of the domestic waste to evaporate it into water vapor.

[0068] In a specific embodiment, Figure 3 As shown, the heating assembly 300 further includes a temperature control switch 320 . The temperature control switch 320 is installed on the reaction chamber 100 , and the temperature control switch 320 is electrically connected to the heating plate 310 .

[0069] The temperature control switch 320 can detect the internal temperature of the accommodating chamber 110. When the internal temperature of the accommodating chamber 110 is lower than the first set temperature, the temperature control switch 320 controls the heating plate 310 to heat; when the internal temperature of the accommodating chamber 110 is higher than the second set temperature, the temperature control switch 320 controls the heating plate 310 to stop heating. This embodiment does not limit the specific structure of the temperature control switch 320, and those skilled in the art can select a suitable temperature control switch 320 as needed. Optionally, a wiring terminal can be set on the temperature control switch 320, and a wire can be connected through the wiring terminal, so that the temperature control switch 320 can be electrically connected to the heating plate 310 and the electric control unit 500 respectively.

[0070] In one embodiment, Figure 1-Figure 5 As shown, the exhaust assembly 400 includes an exhaust fan 410 and a mounting base 420. The mounting base 420 is connected to the exhaust fan 410 and the reaction chamber 100 respectively, and the air inlet of the exhaust fan 410 is connected to the containing chamber 110. The mounting base 420 is provided with an interface 421 connected to the air outlet of the exhaust fan 410.

[0071] The mounting base 420 can be fixedly connected to the exhaust fan 410 and the reaction chamber 100 through fasteners. The interface 421 on the mounting base 420 is arranged opposite to the air outlet of the exhaust fan 410, and the exhaust pipe can be connected through the interface 421 on the mounting base 420. During operation, the exhaust fan 410 can discharge water vapor and other gases in the receiving chamber 110 through the interface 421 and the exhaust pipe to prevent the odor brought by the water vapor and other gases in the receiving chamber 110 from entering the room and affecting the user's experience.

[0072] In a specific embodiment, Figure 5 As shown, the reaction chamber 100 is provided with a hole 130 communicating with the air inlet of the exhaust fan 410 , and the mounting seat 420 is provided with a grille 422 covering the hole 130 .

[0073] Exemplarily, the air inlet of the exhaust fan 410 is arranged opposite to the grille 422 of the mounting seat 420 and the hole 130 of the reaction chamber 100, and the air inlet of the exhaust fan 410, the grille 422 and the hole 130 are of the same shape and size. Schematically, the grille 422 of the mounting seat 420 is located between the air inlet of the exhaust fan 410 and the hole 130. The grille 422 of the mounting seat 420 allows the gas in the receiving chamber 110 to be discharged through the exhaust fan 410, and the grille 422 can also prevent large particles in the receiving chamber 110 from entering the exhaust fan 410, thereby ensuring the service life of the exhaust fan 410.

[0074] With this structure, the grille 422 of the mounting base 420 can ensure the service life of the exhaust fan 410, so that the domestic waste treatment device can operate reliably.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application 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 or all of the technical features therein with equivalents.
