Description

Technical Field

[0001] This utility model relates to the technical field of kitchen and bathroom sewage equipment, and in particular to a kitchen and bathroom sewage device that prevents backflow of odors. Background Technology

[0002] One reason for unpleasant odors in kitchens and bathrooms is backflow from sewage pipes. Existing sewage systems typically address this by using one-way drain valves to prevent backflow. However, the real cause of the backflow is the growth of bacteria on the inner walls of the sewage pipes, and existing sewage systems cannot truly solve this problem. Utility Model Content

[0003] The purpose of this utility model is to provide a kitchen and bathroom sewage discharge device that prevents backflow of odors, so as to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] First, this utility model provides a kitchen and bathroom sewage discharge device to prevent backflow of odors, comprising:

[0006] A sewage pipe having an inlet and an outlet, the inlet being connected to a water tank and the outlet being connected to a sewer, and a first installation port being provided on the side wall of the sewage pipe;

[0007] A sterilization module is sealed to the first mounting port, and the sterilization module is partially located in the sewage pipe.

[0008] By installing a sterilization module on the side wall of the sewage pipe, the module is partially located within the pipe, enabling it to sterilize the inner wall and address the root cause of bacterial adhesion and growth. The sewage pipe has a first installation port through which the sterilization module connects, facilitating module replacement and maintenance.

[0009] As an extension of the above solution, the sterilization module includes a housing and an ultraviolet germicidal lamp. A portion of the housing is placed within the first mounting port, and the ultraviolet germicidal lamp is connected to the housing. The side of the housing connected to the first mounting port is translucent. This arrangement prevents the ultraviolet germicidal lamp from being corroded by wastewater, and because the side of the housing connected to the first mounting port is translucent, the ultraviolet light generated by the ultraviolet germicidal lamp can still pass through the housing.

[0010] As an extension of the above solution, the outer casing is provided with a first slot, and the ultraviolet germicidal lamp is slidably connected to the first slot. This arrangement facilitates the assembly and disassembly of the ultraviolet germicidal lamp from the outer casing.

[0011] As an extension of the above solution, the first slot is located on the side away from the first mounting opening. Specifically, the installed ultraviolet germicidal lamp is located outside the housing, and the first slot is recessed towards the first mounting opening. This arrangement facilitates the installation and removal of the ultraviolet germicidal lamp.

[0012] As an extension of the above solution, the outer casing is made of quartz glass. Using a quartz glass casing allows the ultraviolet light generated by the ultraviolet lamp module to enter the sewage pipe from the outside, simultaneously disinfecting both the inside of the sewage pipe and the outside of the kitchen and bathroom drain.

[0013] As an extension of the above solution, the distance L1 between the first mounting port and the water inlet is less than the distance L2 between the first mounting port and the water outlet. This distance is the distance from the center of the first mounting port to the end of the water inlet or the end of the water outlet. The closer the ultraviolet light module is to the water inlet, the better the sterilization effect on the vicinity of the water inlet, and the better it can prevent backflow of odors.

[0014] As an extension of the above solution, an atomizing tube extending into the sewage pipe is provided on the side of the outer shell connected to the sewage pipe. An atomizer is installed inside the outer shell, connected to an atomizing liquid, and the atomizer is connected to the atomizing tube. By installing an atomizer inside the outer shell and setting the atomizing liquid to a preparation with bactericidal and oil-removing effects, the bactericidal and oil-removing liquid atomized by the atomizer spreads into the sewage pipe through the atomizing tube, achieving better bactericidal effects and a certain degree of oil removal. The atomized bactericidal and oil-removing liquid becomes ultrafine particles that adhere to the pipe wall of the sewage pipe, better dissolving oil stains. The water flowing into the inlet can remove the dissolved oil stains. Furthermore, when sewage flows into the inlet, the bactericidal and oil-removing liquid produced by the atomizer mixes more evenly with the sewage, reacting better with the grease in the sewage.

[0015] More importantly, the ultraviolet light generated by the ultraviolet germicidal lamp will be scattered when it encounters the atomized ultra-fine sterilizing and degreasing liquid particles, resulting in a larger sterilization range inside the sewage pipe.

[0016] As an extension of the above solution, the atomizing tube has a first port connected to the housing and a second port for discharging the atomized liquid, the second port being located opposite to the first port. This arrangement makes it difficult for wastewater to come into contact with the surface of the atomizer, thus extending the service life of the atomizer.

[0017] As an extension of the above solution, the atomizer is an ultrasonic atomizer. Since ultrasonic atomizers are now quite mature, using them can reduce production costs and provide a longer service life.

[0018] As an extension of the above solution, a controller is also included. The ultraviolet lamp module is electrically connected to the controller, which is connected to the outer wall of the sewage pipe. By installing the controller on the outer wall of the sewage pipe and electrically connecting it to the ultraviolet germicidal lamp, it is convenient to control the switching of the ultraviolet germicidal lamp via the controller. In particular, a controller with Internet of Things (IoT) functionality can be selected, allowing users to operate it through a program on a smart device. Furthermore, by placing the controller on the outer wall of the sewage pipe, the space under the sink can be effectively utilized, reducing the number of cable connections.

[0019] The anti-odor kitchen and bathroom drainage device provided by this utility model can sterilize and degrease the drain pipes of kitchen and bathroom sinks, effectively preventing bacterial growth and preventing odors from backing up into the kitchen and bathroom drains. This anti-odor kitchen and bathroom drainage device belongs to the technical field of kitchen and bathroom equipment and is applied to kitchen and bathroom drainage. Attached Figure Description

[0028] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0029] Reference Figures 1 to 3 The following are several embodiments of a kitchen and bathroom sewage discharge device for preventing backflow of odors according to this utility model.

[0030] like Figures 1 to 3 As shown, a kitchen and bathroom wastewater drainage device for preventing backflow of odors includes:

[0031] The sewage pipe 100 has an inlet 101 and an outlet 102. The inlet 101 is connected to a water tank, and the outlet 102 is connected to a sewer. The side wall of the sewage pipe 100 is provided with a first installation port 103.

[0032] A sterilization module 300 is sealed to the first mounting port 103, and the sterilization module 300 is partially located in the sewage pipe 100.

[0033] By installing a sterilization module 300 on the side wall of the sewage pipe 100, the sterilization module 300 is partially located within the sewage pipe 100, enabling sterilization of the inner wall of the sewage pipe 100 and fundamentally solving the problem of bacterial adhesion and growth. The sewage pipe 100 is provided with a first installation port 103, through which the sterilization module 300 is connected. This arrangement facilitates the replacement or maintenance of the sterilization module 300.

[0034] The distance L1 between the first mounting port 103 and the water inlet 101 is less than the distance L2 between the first mounting port 103 and the water outlet 102. This distance is measured from the center of the first mounting port 103 to either the end of the water inlet 101 or the end of the water outlet 102. The closer the sterilization module 300 is to the water inlet 101, the better the sterilization effect on the vicinity of the water inlet 101, and the better it prevents backflow of odors.

[0035] Furthermore, the sterilization module 300 includes a housing 301 and an ultraviolet germicidal lamp 302. The housing 301 is partially placed in the first mounting port 103, and the ultraviolet germicidal lamp 302 is connected to the housing 301. The side of the housing 301 connected to the first mounting port 103 is translucent. This arrangement prevents the ultraviolet germicidal lamp 302 from being corroded by wastewater. Because the side of the housing connected to the first mounting port 103 is translucent, the ultraviolet light generated by the ultraviolet germicidal lamp 302 can still pass through the housing. Using the ultraviolet germicidal lamp 302 reduces production costs.

[0036] Preferably, the ultraviolet light generated by the ultraviolet germicidal lamp 302 can directly radiate to the water inlet 101 and the water outlet 102.

[0037] Furthermore, the anti-odor kitchen and bathroom sewage discharge device in this embodiment also includes a controller 200. The ultraviolet germicidal lamp 302 is electrically connected to the controller 200, and the controller 200 is connected to the outer wall of the sewage pipe 100. By installing the controller 200 on the sewage pipe 100 and connecting it to the ultraviolet germicidal lamp 302, it is convenient to control the switching of the ultraviolet germicidal lamp 302 through the controller 200. In particular, a controller 200 with Internet of Things (IoT) functionality can be selected, allowing users to operate it through software on a smart device. In addition, by placing the controller 200 on the outer wall of the sewage pipe 100, the space under the sink can be effectively utilized, reducing the number of cable connections.

[0038] In some embodiments, in order to facilitate the assembly and disassembly of the ultraviolet germicidal lamp 302 and the housing 301, the housing 301 is provided with a first slot 3011, and the ultraviolet germicidal lamp 302 is slidably connected to the first slot 3011.

[0039] In this embodiment, the first slot 3011 is located on the side away from the first mounting port 103. Specifically, after installation, the ultraviolet germicidal lamp 302 is located outside the housing 301, and the first slot 3011 is recessed towards the first mounting port 103. This arrangement facilitates the installation and removal of the ultraviolet germicidal lamp 302.

[0040] Preferably, the outer casing is made of 301 quartz glass. Using a quartz glass outer casing 301 allows the ultraviolet light generated by the ultraviolet germicidal lamp 302 to penetrate the interior of the sewage pipe 100 from the outside, and also disinfects the exterior of the sewage pipe 100.

[0041] In some embodiments, the side of the outer casing 301 connected to the drain pipe 100 is provided with an atomizing tube 104 extending into the drain pipe 100. An atomizer 400 is provided inside the outer casing 301, connected to an atomizing liquid, and the atomizer 400 communicates with the atomizing tube 104. By providing the atomizer 400 inside the outer casing 301 and setting the atomizing liquid to a chemical agent with bactericidal and oil-removing effects, the bactericidal and oil-removing liquid atomized by the atomizer 400 spreads into the interior of the drain pipe 100 through the atomizing tube 104, achieving better bactericidal effects and a certain degree of oil removal. The atomized bactericidal and oil-removing liquid becomes ultrafine particles, adhering to the inner wall of the drain pipe 100, which can better dissolve oil stains. The water flowing into the inlet 101 can remove the dissolved oil stains. In addition, when sewage flows in from the inlet 101, the bactericidal and oil-removing liquid generated by the atomizer 400 can mix more evenly with the sewage and react better with the grease in the sewage.

[0042] More importantly, the ultraviolet light generated by the ultraviolet germicidal lamp will be scattered when it encounters the atomized ultra-fine sterilizing and degreasing liquid particles, so that the ultraviolet light has a larger sterilization range inside the sewage pipe 100.

[0043] In this embodiment, the atomizing tube 104 has a first port 1041 connected to the housing 301 and a second port 1042 for discharging the atomized liquid, with the second port 1042 located below the first port 1041. This arrangement makes it difficult for wastewater to come into contact with the surface of the atomizer 400, thus extending the service life of the atomizer 400.

[0044] The atomizer 400 is an ultrasonic atomizer. Since ultrasonic atomizers are now quite mature, using them reduces production costs and provides a longer service life.

[0045] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
