Description

Technical Field

[0001] At least one embodiment of the utility model relates to the technical field of sanitary ware, and in particular to a deodorizing device suitable for toilets and a toilet. Background Art

[0002] Toilets are commonly used sanitary ware. When users use the toilet, odorous gases are generated. Currently, the treatment of such odorous gases is generally carried out through windows and exhaust equipment arranged in the toilet.

[0003] However, since the windows and exhaust equipment are located far away from the location where the odorous gas is generated, even in the toilet seat of the device, a long diffusion process of the odorous gas is required when the odorous gas is discharged, which causes the odor mixed in the odorous gas to be diffused into the entire bathroom and remains difficult to dissipate for a long time.

[0004] In view of this, the prior art often adopts two methods to deal with odor. One is to increase the number and / or power of exhaust equipment to speed up the diffusion and discharge of odorous gases, but due to the requirements of comfort such as noise, this method is not effective; the second is to install ultraviolet lamps in the bathroom to remove odors, but due to the long-term exposure to ultraviolet rays, it is easy to cause damage to the human body (such as skin, eyes, etc.), so it is greatly restricted in terms of use process and time.

[0056] Figure 1 It is a structural schematic diagram of a deodorizing device according to an illustrative embodiment of the utility model.

[0057] According to the deodorizing device suitable for toilet provided by the utility model, Figure 1 As shown, it includes a deodorizing mechanism 1 and an exhaust mechanism 2. The deodorizing mechanism 1 is suitable for generating and storing a hydrogen peroxide solution. The exhaust mechanism 2, the air inlet of which is arranged in the toilet seat 33 of the toilet 3 and communicated with the deodorizing mechanism 1, is suitable for extracting at least a part of the odorous gas in the toilet seat 33 into the deodorizing mechanism 1 and mixing it with the hydrogen peroxide solution to remove at least a part of the odor in the odorous gas.

[0058] When users use the toilet, the main components that produce odor (such as bad smell) are sulfides (such as hydrogen sulfide, methyl mercaptan, ethyl mercaptan, etc.), nitrogen-containing substances (such as amino acids, urea, ammonia, creatine, creatinine, etc.), volatile fatty acids (such as acetic acid, propionic acid, butyric acid, etc.) and protein decomposition products (such as indole, skatole, ammonia substances, etc.).

[0059] In this embodiment, at least a portion of the odorous gas volatilized from the toilet seat can be extracted into the hydrogen peroxide (i.e., H2O2) solution of the deodorizing mechanism 1 by the air extraction mechanism 2 disposed in the toilet seat. In this way, the distance between the air inlet and the location where the odorous gas is generated is shortened, and the amount and concentration of the odorous gas diffused from the toilet seat to the outside are reduced, thereby achieving the purpose of deodorization. The hydrogen peroxide generated and stored in the deodorizing mechanism 1 has a good treatment effect on the above-mentioned substances. For example, indole and skatole in the above-mentioned substances are soluble in water, and at least a portion of sulfides (such as hydrogen sulfide), nitrogen-containing substances (such as amino acids and urea) and volatile straight acid (such as acetic acid, propionic acid and butyric acid) can be oxidized under the strong oxidizing property of hydrogen peroxide. Moreover, under the strong oxidizing property of hydrogen peroxide, the biological structure of a portion of bacteria and viruses can also be destroyed, thereby achieving the purpose of further deodorization and disinfection.

[0060] According to the embodiments of the present utility model, Figure 1 As shown, the deodorizing mechanism 1 includes a housing 13, an air intake assembly and an electrode assembly. The housing 13 defines a liquid storage chamber for storing water. The air intake assembly is connected to the liquid storage chamber and is suitable for supplying air to the liquid storage chamber.

[0061] According to the embodiments of the present utility model, Figure 1 As shown, the housing 13 is provided with an exhaust port 11 suitable for exhausting the purified odorous gas.

[0063] In a preferred embodiment, an exhaust port 11 is provided at the top of the shell 13. Furthermore, a liquid injection port 17 suitable for adding water is also provided on the inner wall of one side of the shell 13. Among them, a grille suitable for preventing external foreign matter from entering can be provided in the exhaust port 11, and a detachable cover can be installed on the liquid injection port 17 to seal or open the liquid injection port 17, and water or hydrogen peroxide solution can be injected in the open state to maintain the liquid level of the solution in the liquid storage chamber higher than the upper ends of the cathode 16 and the anode 15, so that the cathode 16 and the anode 15 are preferably immersed in the solution. Preferably, the liquid level of the solution in the liquid storage chamber should also be maintained below the liquid injection port 17 to prevent the solution from overflowing from the liquid injection port.

[0064] According to the embodiments of the present utility model, Figure 1 As shown, the air intake assembly includes a first pump 14, and the exhaust end of the first pump 14 is connected to the first air intake at the bottom of the liquid storage chamber.

[0065] According to the embodiments of the present utility model, Figure 1 As shown, the electrode assembly includes a cathode 16 and an anode 15 which are arranged in parallel and spaced apart. The cathode 16 and the anode 15 are both arranged above the first air inlet.

[0066] In an illustrative embodiment, Figure 1 As shown, the first pump 14 is disposed outside the housing 13 and is adapted to draw air outside the housing into the liquid storage chamber. Specifically, the first pump 14 includes but is not limited to an air pump. It should be understood that the embodiments of the present utility model are not limited thereto.

[0067] For example, the first pump 14 may be disposed in a cavity below the partition 19 , with only the air inlet end of the first pump 14 disposed on the housing 13 and / or exposed to the outside of the housing 13 .

[0068] In an exemplary embodiment, the electrode assembly includes a cathode 16 and at least one anode 15. In a preferred embodiment, Figure 1 As shown, the electrode assembly includes a cathode 16 and two anodes 15 symmetrically arranged on both sides of the cathode. In detail, the cathode 16 and the anode 15 are arranged along the extension direction of the shell 13 (such as Figure 1The cathode 16 and the anode 15 are connected to the electric control assembly 12 and electrically connected so that current passes through the solution in the liquid storage chamber. When the current passes through, a reduction reaction of oxygen occurs on the cathode 16 to generate hydrogen peroxide.

[0069] In an illustrative embodiment, Figure 1 As shown, the cathode 16 is coated with an air barrier net 18 so that the air pumped in by the first pump 14 is maintained near the cathode 16 (such as between the cathode 16 and the anode 15) for a long time. Further, the anode 15 is coated with a cellulose mesh film, which is suitable for inhibiting the oxidative decomposition of hydrogen peroxide by the anode 15. The mesh size of the air barrier net 18 includes but is not limited to being configured to be 0.8 to 2.5 mm.

[0070] In an illustrative embodiment, the anode 15 includes but is not limited to metal plates and meshes that have been surface metal activated. Specifically, it includes but is not limited to one or a combination of titanium, ruthenium, iridium, platinum, stainless steel, and manganese plates or meshes. Among them, the activation method includes but is not limited to one or a combination of chemical oxidation and reduction, electrical oxidation and reduction, and high-temperature oxidation or reduction.

[0071] In an illustrative embodiment, the cathode 16 and the anode 15 can be inverted to reactivate the cathode 15, that is, the used carbon-based material is used as the anode 15, and the used metal material is used as the cathode 16. The carbon-based material is reoxidized, wherein the oxidation time is 200-250 minutes and the oxidation current is 30-80 mA, so that the electrode assembly can achieve a higher hydrogen peroxide production while extending the service life of the device.

[0072] In an illustrative embodiment, the cathode 16 includes, but is not limited to, a carbon-based material co-doped with nitrogen and oxygen, a carbon-based material doped with oxygen, a carbon-based material doped with nitrogen, a carbon-based material doped with boron, or a carbon-based material doped with phosphorus. The carbon-based material includes one or a combination of carbon black, biochar, activated carbon, graphite felt, carbon felt, carbon paper, and carbon cloth.

[0073] In such an embodiment, the electrode assembly is provided with a cathode 16 and multiple anodes 15, which is conducive to increasing the production of hydrogen peroxide. For example, in an actual use scenario, the air extracted by the first pump 14 quickly floats up through the hydrogen peroxide solution under the action of the air isolation net 18. At the same time, the second pump 23 is suitable for extracting the odorous gas in the toilet seat to the bottom of the liquid storage chamber, so that the bubbles pass through the area between the cathode 16 and the anode 15 in sequence during the floating process, so that the injected air, odorous gas and hydrogen peroxide solution are fully contacted, thereby more effectively removing part of the bacteria, viruses and odor molecules in the odorous gas to achieve the effect of deodorization and disinfection. On this basis, the oxidation effect on the surface of the anode 15 also helps to decompose the odor molecules.

[0074] According to the embodiments of the present utility model, Figure 1 As shown, the air extraction mechanism 2 includes a second pump 23, an air inlet pipe 22 and an air outlet pipe 24. The air inlet pipe 22 is provided with a plurality of air inlets, which are arranged at intervals on the toilet seat 33 to extract a portion of the odorous gas in the toilet seat 33. The air outlet pipe 24 is provided between the exhaust end of the second pump 23 and the liquid storage chamber.

[0075] According to the embodiments of the present utility model, Figure 1 As shown, the gas outlet 25 formed by the gas outlet pipe 24 is arranged at the bottom of the shell 13 and is located below the electrode assembly.

[0076] According to the embodiments of the present utility model, Figure 1 As shown, the second pump 23 includes a bidirectional pump having a first state for extracting odorous gas into the liquid storage chamber, and a second state for extracting a portion of the hydrogen peroxide solution in the liquid storage chamber into the toilet seat 33 .

[0077] In an illustrative embodiment, Figure 1 As shown, the end of the air inlet end 22 forms a terminal 21. In detail, the terminal 21 includes but is not limited to a ring-shaped structure configured to fit the shape of a toilet (for example, a roughly elliptical structure that fits the inner edge of a toilet seat; or, for example, a runway-shaped structure that fits the inner edge of a squat toilet). Further, the terminal 21 is provided with a plurality of air inlets spaced apart according to the extension direction of the terminal 21, and when the terminal 21 is arranged on the toilet, at least a portion of the air inlets are arranged facing the interior of the toilet.

[0078] In an illustrative embodiment, Figure 1As shown, one end of the air outlet pipe 24 is connected to the exhaust end of the second pump 23 and extends to the top of the partition of the housing 13. In detail, the air outlet of the air outlet pipe 24 protrudes from the upper end surface of the partition 19, and the air outlet 25 is configured as an aeration mechanism with micropores. Further, the air outlet is preferably arranged below the area between the cathode 16 and the anode 15 so that the odorous gas passing through the area can be fully mixed with the hydrogen peroxide. Among them, the air outlet 25 provided on the air outlet pipe 24 can be arranged to be one or more, for example, it can be arranged as follows Figure 1 It should be understood that the embodiments of the present invention are not limited thereto.

[0079] For example, the number of the gas outlets 25 can also be set to three, four, five or any other number, so as to evenly mix the odorous gas extracted from the toilet seat 33 with the hydrogen peroxide solution.

[0080] In such an embodiment, the air outlet 25 of the air outlet pipe 24 is constructed as an aeration mechanism with micropores. Under the extraction action of the second pump 23, the odorous gas extracted from the toilet seat can be blown into the liquid storage chamber in the form of microbubbles, so that the odorous gas and the hydrogen peroxide solution can be mixed more evenly, so that the bacteria, viruses and other substances carried in the odorous gas can be fully purified by the hydrogen peroxide solution.

[0081] Figure 2 It is a structural schematic diagram of a deodorizing device according to another exemplary embodiment of the utility model, showing a stirring mechanism.

[0082] In an illustrative embodiment, Figure 2 As shown, the deodorizing device further comprises a stirring mechanism 5.

In this way, when the stirring paddle 54 rotates with the stirring shaft 53, a vortex can be formed around the stirring paddle 54 to further enhance the gas-liquid mixing effect of the odorous gas and / or air with the hydrogen peroxide solution. In an exemplary embodiment, as shown in FIG. Figure 1 As shown, the second pump 23 includes but is not limited to a bidirectional pump. Figure 1 The second pump 23 (in the schematic direction of the hollow arrow shown in FIG. 1 ) is suitable for sucking the odorous gas in the toilet seat 33 into the deodorizing mechanism 1; Figure 1 The second pump 23 (in the schematic direction of the solid arrow shown) is suitable for extracting a portion of the hydrogen peroxide solution into the toilet seat 33. In the second state, the air inlet provided on the end head 21 is used as a discharge port for discharging the hydrogen peroxide solution into the toilet seat 33, so that the hydrogen peroxide solution is evenly discharged along the cylindrical wall of the toilet seat 33.

[0085] In an illustrative embodiment, Figure 1 As shown, the deodorizing device suitable for a toilet can be configured as an external structure independent of the toilet.

[0086] For example, the deodorizing mechanism 1 of the deodorizing device can be arranged in the bathroom, and the air inlet pipe 22 (including the end 21) in the air extraction mechanism 2 of the deodorizing device can be arranged in the toilet seat of the toilet.

Further, the end 21 of the air inlet pipe 22 includes but is not limited to being detachably connected to the toilet seat by bonding, snap-fitting, slotting or any other means.

[0088] In another exemplary embodiment, Figure 3 As shown, the deodorizing device suitable for a toilet can be integrated on the toilet. This part is described in detail in the following embodiment of the toilet.

[0089] Figure 3 It is a structural schematic diagram of a toilet according to an illustrative embodiment of the utility model.

[0090] According to the toilet provided by the utility model, Figure 3As shown, it includes a toilet seat 33, a water tank 31 and a deodorizing device. The water tank 31 is connected to the toilet seat 33. The deodorizing mechanism 1 of the deodorizing device is arranged in the water tank 31, and the air inlet of the air extraction mechanism 2 of the deodorizing device is formed on the inner wall of the toilet seat 33 at a position higher than the liquid surface.

[0091] According to the embodiments of the present utility model, Figure 3 As shown, the deodorizing mechanism 1 is isolated from the water tank 31 and is unidirectionally connected to the water tank 31 through the third pump 4 . The third pump 4 is suitable for pumping a portion of the hydrogen peroxide solution into the water tank 31 .

[0092] In an illustrative embodiment, Figure 3 As shown, the toilet includes but is not limited to a toilet, which includes a toilet seat 33, a water tank 31 and a seat ring 32. In detail, a downpipe 37 connected to an external downpipe system is provided at the bottom of the toilet seat 33, and the water tank 31 is provided at one end of the toilet seat 33 (such as Figure 3 Further, the seat ring 32 is installed on the toilet seat 33 in an openable and closable manner.

[0093] In an illustrative embodiment, a water inlet pipe connected to an external water supply system is provided in the water tank 31. In detail, a float 34 is provided at the end of the water inlet pipe, and the float 34 is configured to open or close the water inlet pipe under the buoyancy of the water injected into the water tank 31, so as to inject water into the water tank or seal the water in the water tank 31. Furthermore, a flushing pipe 36 and a drain valve 35 for sealing the flushing pipe 36 are also provided in the water tank 31, wherein the drain valve 35 includes but is not limited to a solenoid valve.

[0094] In an illustrative embodiment, Figure 3 As shown, the end 21 of the air extraction mechanism 2 of the deodorizing device is integrated on the inner wall of the toilet seat 33 of the toilet. In detail, the inner wall of the toilet seat 33 may be formed with an air inlet connected to the air extraction mechanism 2. Further, the deodorizing mechanism 1 of the deodorizing device is installed in the water tank 31 and isolated from the water-filled environment inside the water tank 31.

[0095] In an illustrative embodiment, Figure 3As shown, the deodorizing mechanism 1 is connected to the back plate of the water tank 31. In detail, the electric control component 12 of the deodorizing mechanism 1 is exposed to the outside of the water tank 31 to access the external circuit (such as the wall plug set in the toilet) and is isolated from the toilet 3, and is insulated from the water environment in the water tank 31 of the toilet 3. Further, the liquid storage chamber defined in the shell 13 of the deodorizing mechanism 1 is unidirectionally connected to the water tank 31 through the third pump 4 to allow a part of the hydrogen peroxide solution in the liquid storage chamber to enter the water environment of the water tank 31. In this way, a certain amount of hydrogen peroxide solution can be added to the water in the water tank 31 suitable for flushing the toilet seat 33, so as to flush and disinfect the toilet seat 33 by using the strong oxidizing property of the hydrogen peroxide solution. Among them, the third pump 4 includes but is not limited to using a peristaltic pump to supply sodium hydroxide solution to the water tank 31 in a time-sequential and quantitative manner.

[0096] In a preferred embodiment, the toilet includes but is not limited to a smart toilet. In detail, the electronic control component of the deodorizing device is integrated into the control circuit of the smart toilet. Furthermore, a sensor (such as a pressure sensor and / or an infrared sensor) is provided on the seat ring 32 of the smart toilet, and the sensor is triggered in response to the user's sitting action to identify that someone is using the toilet. Furthermore, the electronic control component 12 is configured to control the deodorizing device to start in response to the trigger signal (such as an electrical signal) of the sensor to perform the deodorizing action, for example, to make the exhaust mechanism 2 extract odorous gas, to make the deodorizing mechanism 1 produce hydrogen peroxide, and to make the third pump 4 supply hydrogen peroxide solution into the water tank 31.

[0097] In an illustrative embodiment, the electronic control component 12 can control at least one of the second pump, the third pump and the electrode assembly based on the timing and / or delay of the signal output by the sensor and / or the smart toilet.

[0098] For example, the working time can be preset, including but not limited to 10 minutes, 20 minutes, 30 minutes, 40 minutes, 50 minutes and any other working time after being triggered, and the working time can be set according to the experience value or calculated. In this way, the odorous gas can be purified and deodorized more completely.

[0099] For example, when there is no user trigger for a long time, it can be turned on at a fixed time, such as 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, 7 hours, 8 hours, 9 hours, 10 hours or other arbitrary time. In this way, it is helpful to prevent the hydrogen peroxide content in the solution from decreasing.

[0100] For example, it can be set to open periodically and run at a fixed time, such as 2 to 4 times in 12 hours, 24 hours or other arbitrary time periods. This is helpful to prevent bacteria from growing in the toilet.

[0101] It should be noted that the main structure of the smart toilet, the control circuit and the sensor provided on the seat 32 of the smart toilet are not the key points of protection of the present invention, and any toilet in the art that can be used to power the deodorizing device and control the deodorizing device can be selected and applied. It should be understood that the embodiments of the present invention are not limited thereto.

[0102] For example, the deodorizing device is also applicable to toilets equipped with a negative pressure mechanism.

[0103] Since the toilet based on the negative pressure mechanism does not use siphoning to flush excrement, a water tank as in the above embodiment is not provided. On this basis, the deodorizing device should be provided outside the toilet, and only the air inlet of the air inlet pipe 22 of the air extraction mechanism 2 of the deodorizing device is integrated into the toilet seat of the toilet.
