Description

Technical Field

[0001] This utility model relates to bathroom products, and more particularly to toilets. Background Technology

[0002] Current common technologies for cleaning ceramic toilets involve adding citric acid and surfactants to the toilet cleaning water. In contrast, ozone has the advantages of broad-spectrum sterilization, no consumables, and no residue, making it environmentally friendly.

[0003] However, ozone decomposes very easily. The advantages and disadvantages of existing solutions for using ozone water to sterilize and clean toilet ceramics are as follows:

[0004] 1) The electrolysis module is directly placed in water to continuously electrolyze and generate ozone. Advantages: Simple structure. Disadvantages: Only forms a supersaturated solution in a localized area, providing only localized sterilization and failing to diffuse into the overall system.

[0005] 2) Add an electrolysis module directly to the flushing pipeline to generate ozone during the flushing process; Advantages: Simple structure. Disadvantages: The water flow rate in the pipeline is usually >10L / min during the flushing process, and the flushing time is short, leaving no water in the pipeline after flushing; Using the electrolysis method requires electrolyzing the water in the pipeline to generate ozone in a very short time, and to achieve a concentration with bactericidal effect, the cost is extremely high, making it impractical.

[0006] 3) The existing solution uses external circulation electrolysis to produce ozone water. Advantages: It can increase the ozone water concentration to a certain extent. However, it requires an electrolysis module to be installed outside the water tank, occupying additional space. Furthermore, the generated ozone needs to pass through pipes into the water tank, only forming a supersaturated solution at the interface and providing only localized sterilization. It lacks overall diffusion capacity due to the lack of disturbance and does not completely sterilize the water inside the tank. Utility Model Content

[0007] The main technical problem to be solved by this utility model is to provide a sterilization device that saves space and can improve the solubility of ozone in water, thereby increasing the sterilization effect.

[0008] To solve the above-mentioned technical problems, this utility model provides a sterilization device, which is placed in a water tank and includes: an outer shell, an ozone generating component and a circulating stirring component placed inside the outer shell;

[0009] The outer shell is provided with a water inlet and a water outlet. The ozone generating component and the stirring and circulating component are arranged between the water inlet and the water outlet along the water flow direction. The circulating stirring component is used to draw water from the water tank into the outer shell through the water inlet, and after the ozone is generated by the ozone generating component, it is stirred and mixed with the water before flowing out through the water outlet.

[0010] In a preferred embodiment: the ozone generating component includes: a cathode conductive sheet, a proton exchange membrane, a catalytic electrode, and an anode conductive sheet; or, the ozone generating component includes: a cathode conductive sheet, a proton exchange membrane, and a catalytic anode conductive sheet.

[0011] In a preferred embodiment: the housing has a gas-liquid mixing chamber between the circulating stirring assembly and the ozone generating assembly.

[0012] In a preferred embodiment: the water inlet is provided at the bottom of the housing, the ozone generating component is disposed inside the housing at a position corresponding to the water inlet, and a flow channel is formed between the ozone generating component and the inner wall of the housing.

[0013] In a preferred embodiment: the circulating stirring assembly includes an impeller and a drive component for driving the impeller to rotate, the air inlet surface of the impeller faces the ozone generating assembly, and the side of the impeller is connected to the water outlet.

[0014] In a preferred embodiment, the drive element includes a magnet fixedly connected to the shaft of the impeller and a coil disposed within the housing.

[0018] In a preferred embodiment, the flushing pipeline is a dual-hole valve-cut system, a dual-hole interconnection system, or a single-hole rotary flushing system.

[0019] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0020] This invention provides a sterilization device that can be placed directly in a water tank without generating additional volume, thus saving space to the greatest extent.

[0021] This invention provides a sterilization device that, when placed in a water tank, achieves both ozone generation and ozone dissolution in the water within the device itself. Compared to transporting generated ozone to the water tank via pipelines, this significantly improves the mixing efficiency of ozone and water. Furthermore, ozone transported via pipelines is bulky, resulting in a relatively low dissolution rate even with impeller pump agitation. Placing the sterilization device in the water tank allows the generated ozone to directly mix with the water before being agitated by the impeller, greatly enhancing dissolution efficiency.

[0022] This invention provides a sterilization device. Placing the sterilization device in a water tank allows the water flowing out of the sterilization device to agitate the water in the tank, thus preventing the ozone mixed in the water from dissipating and ensuring it is fully dissolved in the water tank.

[0034] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0035] Example 1

[0036] refer to Figures 1-6 This embodiment provides a toilet, including a toilet bowl 1, a water tank 2, and a flushing assembly. The flushing assembly includes an inlet valve 3, a flushing pump 4, and a flushing pipe 5. The inlet end of the inlet valve 3 is connected to the municipal water supply network, and the outlet end is connected to the water tank 2. The inlet end of the flushing pump 4 is connected to the water tank 2, and the outlet end is connected to the toilet bowl 1 through the flushing pipe 5. Water can be added to the water tank 2 through the inlet valve 3, and the flushing pump 4 is used to pump water from the water tank 2 and flush it into the toilet bowl 1 through the flushing pipe 5. In this embodiment, the flushing pipe 5 adopts a dual-hole valve switching system, that is, the flushing flush and the main flush are separated, and a mechanical switching valve 6 is set on the flushing system to allow the water pumped by the flushing pump 4 to enter the main flush or the flushing flush.

[0037] In this embodiment, to achieve the function of disinfecting and sterilizing the toilet bowl 1 during flushing, a sterilization device 7 is installed in the toilet tank 2. The function of the sterilization device 7 is to generate ozone and dissolve the ozone in the water in the tank 2, so that ozone water with a sterilizing effect is formed in the tank 2. Since the water in the tank 2 remains in a relatively stable state when not in use, the environment for generating and dissolving ozone is relatively stable and long-term, which can increase the concentration of ozone water in the tank 2 and achieve a very good sterilization effect. However, existing technologies often place the ozone-generating electrolysis module in the flushing pipe 5. However, the flushing pipe 5 only has water during flushing, which is a very short time with a huge flow rate. This results in insufficient time for electrolysis to generate and dissolve a sufficient concentration of ozone, leading to an unsatisfactory sterilization effect.

[0038] In this embodiment, the sterilization device 7 includes: a shell 71, an ozone generating component 72 placed inside the shell 71, and a circulating stirring component 73. The shell 71 is provided with an inlet 711 and an outlet 712. The ozone generating component 72 and the circulating stirring component are arranged between the inlet 711 and the outlet 712 along the water flow direction. The circulating stirring component 73 is used to draw water from the water tank 2 into the shell 71 through the inlet 711, and after passing through the ozone generating component 72 to generate ozone, it is mixed with the water and then flows out through the outlet 712. It can be seen that after the ozone generating component 72 generates ozone, it is directly mixed with the water flowing through the shell 71. Then, it is drawn into the circulating stirring component 73 and thoroughly mixed and cut, which can greatly improve the ozone dissolution efficiency.

[0039] To achieve ozone production via electrolysis, the ozone generating assembly 72 includes: a cathode conductive plate 721, a proton exchange membrane 722, a catalytic electrode 723, and an anode conductive plate 724 arranged sequentially along the water flow direction. The principle of ozone production is that a low-voltage DC current is applied to the anode conductive plate 724 and the cathode conductive plate 721. Water is separated into hydrogen and oxygen molecules through proton exchange at the proton exchange membrane 722. Hydrogen is directly emitted from the cathode conductive plate 721, while oxygen molecules gain energy through electron excitation generated by a high-density current at the anode conductive plate 724 and polymerize into ozone. As a simple alternative to this embodiment, the cathode conductive plate 721, proton exchange membrane 722, catalytic electrode 723, and anode conductive plate 724 can also be arranged sequentially against the water flow direction or at a certain angle to the water flow direction (e.g., perpendicular). Alternatively, the catalytic electrode 723 and the anode conductive plate 724 can be integrated into a single catalytic anode conductive plate.

[0040] Furthermore, the bottom of the outer casing 71 is provided with the water inlet 711, and the ozone generating component 72 is disposed inside the outer casing 71 at a position corresponding to the water inlet 711, and a flow channel is formed between the ozone generating component 72 and the inner wall of the outer casing 71. In this way, the water flowing into the water inlet 711 is divided into two parts: one part passes through the ozone generating component 72 to generate ozone, and the other part flows directly into the flow channel.

[0041] The outer casing 71 contains a gas-liquid mixing chamber 74 between the circulating stirring assembly 73 and the ozone generating assembly 72. When the circulating stirring assembly 73 draws water and ozone generated by the ozone generating assembly 72, the water and ozone mix in the gas-liquid mixing chamber 74 and are then drawn in by the circulating stirring assembly 73 for further mixing. Specifically, the circulating stirring assembly 73 includes an impeller 731 and a drive component that drives the impeller 731 to rotate. The suction side of the impeller 731 faces the ozone generating assembly 72, and the side of the impeller 731 is connected to the water outlet 712. When the impeller 731 rotates, its air inlet surface can draw water from the water tank 2 into the water inlet 711. Part of the water passes through the ozone generating assembly 72 to generate ozone, while the other part of the water directly enters the gas-liquid mixing chamber 74. In the gas-liquid mixing chamber 74, the ozone and water mix and are further mixed by the impeller 731 before being discharged into the water tank 2 from the water outlet 712. The ozone-containing water discharged into water tank 2 will agitate the original water in water tank 2, so that the water in water tank 2 and the ozone-containing water are fully mixed, reducing the rate at which ozone gas rises and overflows, increasing the time for ozone to remain in the water, dissolve and sterilize, and repeatedly circulating in water tank 2 to kill bacteria and produce ozone water with sterilization effect.

[0042] To drive the impeller 731 to rotate, the driving component includes a magnet 732 fixedly connected to the shaft of the impeller 731 and a coil placed inside the housing 71. When energized, the coil generates a magnetic field, which drives the magnet 732 to rotate, thereby driving the impeller 731 to rotate. The method of using an energized coil to drive the magnet 732 is widely used in existing motors; therefore, this embodiment only describes its principle, and the specific structure will not be elaborated upon further.

[0043] In this embodiment, after the toilet finishes flushing, the inlet valve 3 opens to replenish water to the water tank 2. After the water tank 2 is replenished, the toilet's main control outputs a control signal to the electrolysis control board to control the sterilization device 7. The positive and negative terminals of the power drive circuit on the electrolysis control board are connected to the anode conductive plate 724 and the cathode conductive plate 721, respectively, and are also connected to the coil. During operation, the power drive circuit on the electrolysis control board is turned on, energizing the anode conductive plate 724 and the cathode conductive plate 721, and the coil also generates a magnetic field, causing the ozone generating component 72 and the circulating stirring component 73 to start working. After the predetermined time has elapsed, the toilet's main control stops the sterilization device 7. At this point, the sterilization device 7 has completed the disinfection of the water tank 2 and prepared the tap water in the water tank 2 into ozone water with sterilization effect.

[0044] Example 2

[0045] refer to Figure 7 and Figure 8The difference between this embodiment and embodiment 1 is that a liquid level sensor is installed in the water tank 2. The liquid level sensor is connected to the electrolysis control board, which controls the sterilization device 7.

[0046] This ensures that the sterilization device 7 will only be activated when the liquid level in water tank 2 meets the height set by the liquid level sensor. This is because the electrolysis control board receives the signal from the liquid level sensor and then sends a control signal to activate the sterilization device 7. This guarantees that the sterilization device 7 will only be activated when there is water in water tank 2. This is primarily to prevent situations where, during a water outage, the water in water tank 2 is drained, but the sterilization device 7 is still activated, potentially leading to electrode burn-out and damage.

[0047] Example 3

[0048] refer to Figure 9 The difference between this embodiment and embodiment 1 is that the mechanical switching valve 6 in embodiment 1 is replaced with an electronic switching valve 8. The purpose of both is to allow the water pumped by the flushing pump 4 to enter the main flush or the ring flush.

[0049] Example 4

[0050] refer to Figure 10 The difference between this embodiment and Embodiment 1 is that the mechanical switching valve 6 in Embodiment 1 is replaced with a three-way valve 9. In this way, the water pumped by the flushing pump 4 enters both the main flush and the ring flush simultaneously, that is, the main flush and the ring flush exit water at the same time, realizing a dual-hole interconnected system.

[0051] Example 5

[0052] refer to Figure 11 The difference between this embodiment and embodiment 1 is that the mechanical switching valve 6 and the main punch in embodiment 1 are removed, and only the ring punch is retained to form a single-hole rotary punching system.

[0053] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
