Description

Technical Field

[0001] This application relates to the field of home health, specifically to an electrolysis system, a smart toilet seat cover, and a smart toilet. Background Technology

[0002] In situations requiring surface disinfection of living or closely contacted environments (such as the ceramic walls and seats of smart toilets), atomization disinfection technology demonstrates its advantages due to its comprehensive coverage and ease of use. Among these technologies, electrolyzing saline solution to generate hypochlorous acid on-site and then atomizing it is a highly efficient and environmentally friendly approach.

[0003] Hypochlorous acid atomization technology is a common disinfection technology. The disinfection technology itself is relatively simple. An electrolytic plate electrolyzes salt water to generate hypochlorite ions, and the atomizer vibrates to produce a mist containing hypochlorous acid. However, this technology is rarely used in the field of smart toilets. The main reason is that the chlorine content of the mist produced by the atomizer is not easy to control. Too high a chlorine content will irritate the user's skin, while too low a chlorine content will not have a bactericidal effect. Existing technologies usually focus on electrolysis efficiency or atomization effect itself, and lack systematic control of the concentration throughout the entire cycle. Summary of the Invention

Detailed Implementation

[0019] refer to Figures 1-5 The present invention relates to an electrolysis system, including a liquid supply assembly 100, an electrolysis assembly 200, and a control device (not shown in the figure). The liquid supply assembly 100 includes a first container 110, which may include a bottom box 160 and a top cover 170. The bottom box 160 is provided with a partition plate 180 to divide the interior of the first container into a first cavity 111 and a second cavity 112. The bottom of the partition plate 180 is provided with an opening 190, and the first cavity 111 and the second cavity 112 are connected through the opening 190. The first cavity 111 is used to store sodium chloride. The second cavity 112 is provided with a first liquid inlet channel 130 and a first liquid outlet 140. The first liquid inlet channel 130 is connected to a water source through a water inlet assembly to supply water to the second cavity 112. The electrolysis system further includes a second container 500, which is hollow to form a third cavity 510. The electrolysis component 200 is disposed inside the second container 500. The second container 500 is provided with a second inlet and a second outlet. The first outlet 140 is connected to the second inlet to deliver sodium chloride solution into the second container 500. The second outlet is used to output the sodium hypochlorite solution generated by electrolysis to the outside. The water inlet assembly includes a distribution valve 700, which is connected to the control device. The control device is used to control the opening degree of the distribution valve 700 so that the flow rate of water entering the second cavity 112 is a preset flow rate. The control device is also used to control the electrolysis device 200 to stop electrolysis when the single electrolysis time of the electrolysis device 200 reaches the preset time.

[0020] In this application, sodium chloride is stored in the first cavity 111, and the second cavity 112 and the first cavity 111 are connected through the opening 190. This allows water from the second cavity 112 to enter the first cavity 111, carrying away the salt in the first cavity 111 and flowing back into the second cavity 112, then into the second container 500 through the first outlet 140. This process is a controlled flow dynamic mass transfer process. The greater the water flow rate, the greater the mass of salt dissolved from the salt surface, and the higher the concentration of the sodium chloride solution. Therefore, the water flow rate becomes the determining factor for the concentration of sodium chloride solution delivered to the second container 500 each time. Controlling the water flow rate within a preset range also controls the concentration of the sodium chloride solution within a preset range, which lays the foundation for achieving an effective chlorine concentration within the preset range in the final reaction. Therefore, in this application, a distribution valve 700 is provided in the water inlet assembly. By controlling the opening and closing degree of the distribution valve 700, the water flow rate can be controlled within the preset range.

[0021] Regarding the specific water flow rate setting, it can be derived based on the required effective chlorine concentration and the water level in the second container 500. For example, according to Article 3.5 of my country's "Technical Specification for Hygienic Quality of Sodium Hypochlorite Disinfectant", the permissible effective chlorine content for sterilization on general object surfaces is 100mg / L to 150mg / L. This embodiment uses the lowest effective chlorine content of 100mg / L as the target value for specific explanation. It should be noted that the effective chlorine concentration mentioned in this application is expressed as the equivalent concentration of Cl2.

[0022] To achieve an available chlorine content of 100 mg / L, the solution needs to contain 100 mg of available chlorine per liter. Assuming the solution volume is 1 L, the required mass of available chlorine is 100 mg / L × 1 L = 100 mg = 0.1 g. The reaction for electrolyzing brine to produce sodium hypochlorite (available chlorine) is: NaCl + H₂O → NaClO + H₂O 2，To generate 1 mol Cl₂, 1 mol NaCl is required. The molar mass of Cl₂ is 71 g / mol, and the molar mass of NaCl is 58.5 g / mol. Therefore, the required NaCl mass = 0.1 * (58.5 / 71) = 0.0824 g. 0.0824 g of NaCl dissolved in 1 L of water has a mass concentration of approximately 82.4 mg / L, or a mass fraction of 0.00824%. However, this concentration is a theoretical value. In practical applications, the electrolysis process relies on ion migration to conduct current. An 82.4 mg / L solution has insufficient conductivity, leading to increased voltage and energy consumption in the electrolytic cell, and potentially even preventing the maintenance of a stable electrolytic reaction. Furthermore, not all electrical energy is used to generate available chlorine during electrolysis; some current may be used for side reactions, such as chlorine disproportionation to form chlorate, oxygen evolution, or chlorine loss. Additionally, the NaCl conversion rate is not 100%, and the concentration of NaCl gradually decreases as it is continuously consumed during electrolysis. Finally, based on industry experience, for most electrolytic cell designs, NaCl... The concentration usually needs to be maintained above 0.1 mol / L to obtain sufficient conductivity. Therefore, in order to maintain conductivity and electrolysis stability, the theoretical value above needs to be multiplied by a coefficient. In this embodiment, this coefficient is set to 72, so that the actual concentration is greater than 0.1 mol / L. That is to say, to produce an effective chlorine concentration of 100 mg / L, the actual NaCl concentration in the solution must reach at least 0.00824%*72=0.6%.

[0023] Regarding the determination of the concentration of sodium chloride solution obtained by dissolving salt at a certain water flow rate, the method in this embodiment is to measure the volume of sodium chloride solution loaded in the second container 500 in a single electrolysis, determine this volume and the mass of salt to be dissolved at a given concentration, and estimate the mass of salt dissolved in a single electrolysis by measuring how many electrolysis cycles a certain amount of sodium chloride is consumed. Then, compare this mass with the mass of salt to be dissolved to determine whether the concentration of sodium chloride solution obtained at a certain flow rate meets the requirements. Specifically, in this embodiment, the second container 500 is filled with 75 ml of brine for electrolysis each time. Thus, in order to achieve a brine concentration of 0.6%, approximately 0.5 g of salt needs to be dissolved. In order to ensure that the amount of salt carried away each time liquid is added to the second container 500 is controlled to be 0.5 g, it has been experimentally determined that the inlet water flow rate needs to be controlled at 700 ml / min. The specific determination method involves placing 40g of salt in the first chamber 111 and calculating how many times the second container 500 needs to be injected to consume the 40g of salt under different flow rates. This allows for the estimation of the amount of salt consumed in each injection. Experiments showed that when the water flow rate was 700ml / min, the 40g of salt was consumed in 80 injections, meeting the preset standard. When the required effective chlorine content or the amount of salt water in the second container 500 for each reaction is different, the above approach can be used to estimate the amount of salt to be dissolved and removed in each injection, and the required water flow rate can be measured. The water flow rate is controlled by adjusting the opening and closing of the distribution valve 700, thereby precisely controlling the amount of salt dissolved and removed in each injection, ultimately ensuring that the concentration of the sodium chloride solution participating in the reaction is within the preset range. After obtaining a sodium chloride solution with a concentration within a preset range, the effective chlorine production rate of the electrolysis reaction under a specific concentration of sodium chloride solution and electrolysis current is measured. The electrolysis time of the electrolysis device is controlled according to the formula: Electrolysis time = Total effective chlorine required / Effective chlorine production rate, to obtain the required total chlorine production, thereby obtaining a sodium hypochlorite solution of the desired concentration. In this embodiment, the operating current of the electrolysis device 200 is 700 mA, and the measured effective chlorine production rate is 7.5 mg / min. During the electrolysis reaction, the loss of solution volume is minimal, and the solution volume can be considered constant. With 75 ml of solution, to achieve an effective chlorine content of 100 mg / L, the required total effective chlorine is 7.5 mg. Therefore, the reaction time is controlled to be 1 minute. The reaction time of 1 minute is written into the control program. When the reaction time is reached, the control device controls the electrolysis device 200 to stop electrolysis. When the dependent variables affecting the chlorine production rate, such as the sodium chloride solution and the operating current, change, the chlorine production rate can be re-measured, and the required reaction time can be calculated according to the above formula. Similarly, when the required total chlorine production is different, the required reaction time can be written into the control device according to the formula.Once the electrolysis time reaches the preset time, the electrolysis device 200 stops electrolysis, and the concentration of the sodium hypochlorite solution produced reaches the preset concentration requirement. At this time, the sodium hypochlorite solution can be transported to the object that needs to be disinfected to disinfect the object. Specifically, it can be transported through a pipeline or sprayed after atomization. This embodiment does not limit the specific method.

[0024] In some embodiments, the second container is provided with a water level detection device, which is connected to the control device. When the liquid level in the second container 500 reaches the water level detection device, the control device controls the water inlet assembly to stop water intake.

[0025] A water level detection device is installed in the second container 500. When the liquid level in the second container 500 reaches the position of the water level detection device, the water inlet component is controlled to stop water intake. The water in the first container 100 flows in and out immediately, that is, after entering the first container 100 to flush and dissolve the salt, it flows into the second container 500. The first container 100 is equivalent to a water pipe and does not store water. Therefore, after the water inlet component stops water intake, the liquid level in the second container 500 is fixed. Even if there is residual water in the first container 100, it is very small and its impact on the liquid level in the second container 500 is negligible. In this embodiment, by setting up a water level detection device, the amount of liquid entering the second container 500 is precisely controlled, and the automatic stopping of liquid intake is achieved.

[0026] In some embodiments, the water level detection device includes a first water level probe 810 and a second water level probe 820, which are installed at the same height within the second container 500.

[0027] In some embodiments, a filter 120 is installed at the opening.

[0028] In this embodiment, a filter screen 120 is installed at the opening to ensure that the sodium chloride in the first cavity 111 can only enter the second cavity 112 after it is dissolved and forms a sodium chloride solution. This allows the first cavity 111 and the second cavity 112 to exchange salt water of a set concentration, resulting in a more stable concentration of sodium hypochlorite.

[0029] In some embodiments, the second cavity 112 is provided with an air inlet 150, which is connected to the outside atmosphere, or an air pump is installed at the air inlet 150.

[0030] In this embodiment, an air inlet 150 is provided in the second cavity 112, which is connected to the outside atmosphere. Alternatively, an air pump can be installed at the air inlet 150 to use atmospheric pressure or the air pump to send air into the second cavity 112, so as to drain the sodium chloride solution in the second cavity 112 through the water outlet 140, thereby preventing sodium chloride solution from remaining in the second cavity 112 and evaporating and crystallizing, which would affect the concentration of sodium chloride solution during subsequent liquid intake.

[0031] In some embodiments, the electrolysis system further includes an atomizing component 300, which is disposed in the second container 500 and connected to the control device. The atomizing component 300 is used to atomize the sodium hypochlorite solution. The atomized sodium hypochlorite solution is sprayed out through a second outlet. After the control device controls the electrolysis device 200 to stop electrolysis, it controls the atomizing device 300 to start.

[0032] In this embodiment, an atomizing component 300 is set in the electrolysis system to atomize the sodium hypochlorite solution before spraying it out, which can sterilize and disinfect the surface of the object more widely and evenly.

[0033] In some embodiments, the second container is provided with a drain port 520, and the electrolysis system further includes a liquid pump 600, which is used to pump out the solution in the second container 500 and discharge it through the drain port 520. Before the control device starts to pump water into the water inlet assembly, it controls the liquid pump 600 to empty the solution in the second container 500.

[0034] In this embodiment, a liquid pump 600 is provided and connected to a control device. Before the water inlet assembly starts to fill with water, the control device controls the liquid pump 600 to empty the solution in the second container 500. This prevents the solution remaining in the second container 500 from mixing with the newly added sodium chloride solution, which would increase the concentration of the saline solution and cause the resulting sodium hypochlorite solution to have an excessively high concentration, potentially causing irritation to the human body.

[0035] One embodiment of this application provides an intelligent toilet seat cover, including a spray gun and an electrolysis system as described in any of the above embodiments, wherein the spray gun is connected to the drain port, and a liquid pump is disposed between the spray gun and the drain port to pump the solution of the second container to the spray gun.

[0036] In this embodiment, excess sodium hypochlorite solution is transported to the spray gun through the drain port, which can sterilize and disinfect the spray gun and improve the utilization rate of sodium hypochlorite solution.

[0037] In some embodiments, the smart toilet seat also includes a seat ring, a flip cover, and a detection switch. The flip cover is rotatably connected to the seat ring, and the detection switch is installed between the seat ring and the flip cover. The detection switch is electrically connected to the control device. When the detection switch detects that the flip cover is flipped open relative to the seat ring, the control device controls the sterilization system to be disabled.

[0038] In this embodiment, the sterilization system can only be activated when the lid is closed to sterilize and disinfect the toilet. When the lid is flipped open relative to the seat ring, the sterilization system is prohibited from being activated to prevent sodium hypochlorite vapor from drifting outside and being inhaled by the user.

[0039] One embodiment of this application provides a smart toilet, the smart toilet including a smart toilet seat as described in any of the above embodiments.
