[0002] With the development of smart homes, kitchen and bathroom equipment will be equipped with automatic disinfection functions to prevent the growth of bacteria and ensure the cleanliness and safety of kitchen and bathroom equipment.

[0003] In the related art, the method for generating electrolyzed water by the disinfection component in kitchen and bathroom equipment is as follows: using the chloride ions in tap water to perform electrolysis to generate hypochlorous acid and other oxides (specifically ozone, etc.) to form disinfectant water to disinfect the parts of kitchen and bathroom products that need to be disinfected.

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0035] In the related art, the method for generating electrolyzed water by the disinfection component in kitchen and bathroom equipment is as follows: using the chloride ions in tap water to perform electrolysis to generate hypochlorous acid and other oxides (specifically ozone, etc.) to form disinfectant water to disinfect the parts of kitchen and bathroom products that need to be disinfected.

[0036] However, the chloride ion content in water from different regions varies greatly, and the chloride ion concentration in tap water in most areas is often low, which brings limitations to the electrolysis of tap water, resulting in unsatisfactory bactericidal effect of the produced disinfectant. To solve the above problems, salt needs to be added artificially, but this will cause the chloride ion concentration to be very high, and the concentration of the disinfectant after electrolysis is too high. Excessive concentration of sodium hypochlorite poses a high safety risk to the human body.

[0037] In order to solve the above problems, the present application provides a liquid slow-release device and kitchen and bathroom equipment to solve or improve the problem of excessively high chloride ion concentration in electrolyzed water.

[0038] Combine the following Figure 1 to Figure 2 , describing an embodiment of the present application.

[0039] According to an embodiment of the present application, on the one hand, a liquid slow-release device is provided, such as Figure 1As shown, it includes a primary water tank 1, a secondary water tank 2 and a slow-release rod 3. The primary water tank 1 is used to store concentrated brine; the secondary water tank 2 is used to store brine for electrolysis; the slow-release rod 3 connects the primary water tank 1 and the secondary water tank 2. The slow-release rod 3 is a rod body with a connected porous structure, which can make the concentrated brine in the primary water tank 1 diffuse into the secondary water tank 2.

[0040] Specifically, the primary water tank 1 and the secondary water tank 2 are both liquid storage containers, and their materials are plastic; their shapes can be any shapes such as a cuboid, a cylinder, a trapezoid, etc., and their shapes can be adjusted according to the needs and the requirements of the design space.

[0041] It should be noted that the above-mentioned “the slow-release rod 3 is a rod body with an interconnected porous structure, which can make the concentrated brine in the primary water tank 1 diffuse into the secondary water tank 2”, that is, the interior of the slow-release rod 3 is provided with an interconnected porous structure, and the epidermis can be a closed epidermis or an epidermis with multiple holes. Preferably, the epidermis is an epidermis with multiple holes; the slow-release rod 3 can be any one of a porous cotton fiber rod, a porous ceramic rod and a porous polyurethane sponge. Preferably, the slow-release rod 3 is a porous cotton fiber rod, which is cheap and has good water absorption.

[0042] It should also be noted that the "concentrated brine" in "the primary water tank 1 is used to store concentrated brine" refers to saturated concentrated brine, or nearly saturated concentrated brine, or brine with a chloride ion concentration higher than the chloride ion concentration in electrolyzed water that meets disinfection requirements.

[0043] It should be noted that the increase speed of chloride ion concentration in the secondary water tank 2 can be adjusted by adjusting the diameter of the slow-release rod 3; the water molecules in the secondary water tank 2 can also be replenished to the primary water tank 1 through the slow-release rod 3.

[0044] In this embodiment, if Figure 1 As shown, by connecting the primary water tank 1 and the secondary water tank 2 through a slow-release rod 3 with a porous structure, the concentrated brine in the primary water tank 1 and the brine in the secondary water tank 2 are slowly diffused and mixed through the slow-release rod 3, so as to slowly increase the concentration of chloride ions in the electrolyzed water in the secondary water tank 2, which not only avoids the problem of low chloride ion concentration in the electrolyzed water and improves the disinfection effect of the electrolyzed water; but also avoids making the ion concentration in the brine used for electrolysis in the secondary water tank 2 too high, thereby ensuring that the concentration of sodium hypochlorite in the water after electrolysis is within a safe range to avoid damage to the human body.

[0045] In one embodiment, Figure 1As shown, the liquid slow-release device also includes a control module, a through hole 21 is provided on the secondary water tank 2, an isolation column 22 is provided in the secondary water tank 2, one end of the isolation column 22 is connected to the through hole 21, and the other end of the isolation column 22 extends along the height direction of the secondary water tank 2, a slow-release rod 3 passes through the isolation column 22, one end of the slow-release rod 3 located in the secondary water tank 2 is higher than the isolation column 22, and the other end of the slow-release rod 3 is located in the primary water tank 1, and at least a part of the space between the slow-release rod 3 and the inner wall of the isolation column 22 is sealed and blocked by a sealing component 23;

[0046] A drainage part 24 is provided on the secondary water tank 2. The water inlet of the drainage part 24 is lower than the top of the isolation pipe column 22, which is used to lower the liquid level in the secondary water tank 2. The drainage part 24 is connected to the control module, and the control module can control the drainage action of the drainage part 24.

[0047] It should be noted that the through hole 21 can be set on the side of the secondary water tank 2 (not shown in the figure). In this case, the isolation column 22 is bent, first extending one end in the horizontal direction and then bending upward to extend; of course, preferably, Figure 1 As described above, the through hole 21 is arranged at the bottom of the secondary water tank 2. At this time, the isolation pipe column 22 is a pipe body extending vertically toward each other.

[0048] It should be noted that in the present embodiment, "at least a portion of the space between the slow-release rod 3 and the inner wall of the isolation column 22 is sealed by the sealing component 23", that is, the sealing component 23 can seal all the space between the slow-release rod 3 and the isolation column 22, or only a small section of the space between the slow-release rod 3 and the isolation column 22, or any end of the isolation column 22, the main purpose of which is to prevent water leakage.

[0049] Specifically, the isolation column 22 can be a blow-molded product that is integrated with the secondary water tank 2, or the isolation column 22 can be connected to the secondary water tank 2 by welding or by a sealing connection with a connector.

[0050] In this embodiment, if Figure 1 As shown, by setting an isolation column 22 in the secondary water tank 2, one end of the isolation column 22 is connected to the through hole 21 on the secondary water tank 2, and the other end of the isolation column 22 extends along the height direction of the secondary water tank 2, and the slow-release rod 3 passes through the isolation column 22, one end of the slow-release rod 3 is higher than the top of the isolation column 22, and the other end of the slow-release rod 3 is located in the primary water tank 1, so that, as shown in FIG. Figure 2 As shown, after a certain amount of brine in the secondary water tank 2 is consumed, water is replenished into the secondary water tank 2, and the replenished water level is made to exceed the top of the isolation column 22, so that the concentrated brine in the primary water tank 1 diffuses into the secondary water tank 2 through the slow-release rod 3, thereby slowly increasing the concentration of chloride ions in the secondary water tank 2.

[0051] After the set conditions are met (such as timing from the start of water replenishment into the secondary water tank 2, continuing the set time, etc.), the control module controls the drainage part 24 to perform drainage. Since the liquid inlet of the drainage part 24 is lower than the top of the isolation column 22, the liquid level in the secondary water tank 2 can be lowered to below the top of the isolation column 22, thereby achieving the disconnection between the primary water tank 1 and the secondary water tank 2, preventing the concentrated brine in the primary water tank 1 from continuing to diffuse into the secondary water tank 2, and continuously increasing the concentration of chloride ions in the secondary water tank 2, thereby completely avoiding the problem of excessive chloride ions in the secondary water tank 2, and further reducing the risk of damage to the human body.

[0052] In one embodiment, Figure 1 As shown, the liquid dilution device also includes a concentration sensor 4, which is arranged in the secondary water tank 2 and is used to measure the concentration of chloride ions. The concentration sensor 4 and the drainage part 24 are both connected to the control module. The control module can control the drainage part 24 to drain water according to the concentration standard signal input by the concentration sensor 4.

[0053] Specifically, the concentration sensor 4 is a TDS sensor, where TDS stands for Total Dissolved Solids, a sensor used to detect the total dissolved solids content in water. It can be purchased on the market, and the specific model can be selected according to actual needs; of course, the concentration sensor 4 can also be other types of sensors, as long as the sensor can reflect the change in chloride ion concentration in the solution.

[0054] In this embodiment, if Figure 2 As shown, the concentration sensor 4 can directly detect the concentration of chloride ions in the secondary water tank 2. When the concentration of chloride ions in the secondary water tank 2 reaches the set requirements, the control module determines whether it meets the standards based on the concentration signal transmitted by the concentration sensor 4 in real time. When the information transmitted by the concentration sensor 4 is determined to be a standard-reaching signal, the control module sends a drainage action to the drainage part 24 to lower the liquid level in the secondary water tank 2, cut off the concentrated brine in the primary water tank 1 from continuing to diffuse into the secondary water tank 2, and increase the chloride ion concentration in the secondary water tank 2. The setting of the concentration sensor 4 can more accurately control the accuracy of the concentration of chloride ions in the secondary water tank 2, and eliminate the influence of various factors such as discharge temperature and water pressure on the accuracy of the chloride ion content in the secondary water tank 2.

[0055] In one embodiment, Figure 1As shown, a water inlet pipe 25 is provided on the secondary water tank 2, and a first liquid level sensor 26 and a second liquid level sensor 27 are provided in the secondary water tank 2. The first liquid level sensor 26 is located higher than the top of the isolation column 22, and the second liquid level sensor 27 is located lower than the water inlet of the drainage part 24. The first liquid level sensor 26 and the second liquid level sensor 27 are both connected to the control module;

[0056] Among them, when the liquid level in the secondary water tank 2 drops to the second liquid level sensor 27, the control module controls the water inlet pipe 25 to open; when the liquid level in the secondary water tank 2 rises to the first liquid level sensor 26, the control module controls the water inlet pipe 25 to close.

[0057] Specifically, the first liquid level sensor 26 and the second liquid level sensor 27 are both existing products and can be purchased on the market; more specifically, the first liquid level sensor 26 and the second liquid level sensor 27 can be fixed to the inner wall surface of the secondary water tank 2 by gluing or welding.

[0058] In this embodiment, if Figure 2 As shown, by the position of the first liquid level sensor 26 being higher than the top of the isolation column 22, when the secondary water tank 2 is replenished with water through the water replenishing pipe, it is possible to ensure that the liquid level of the replenished water is higher than the isolation column 22, thereby achieving connectivity between the primary water tank 1 and the secondary water tank 2, so that the concentrated brine in the primary water tank 1 can diffuse into the secondary water tank 2, thereby increasing the concentration of chloride ions in the secondary water tank 2; at the same time, the position of the second liquid level sensor 27 is lower than the position of the water inlet of the drainage portion 24, thereby ensuring that when the liquid level in the secondary water tank 2 is lower than the second liquid level sensor 27, the secondary water tank 2 is replenished with water in time, thereby avoiding water shortage in the secondary water tank 2, thereby realizing automatic control of the liquid slow-release device.

[0059] In one embodiment, Figure 1 As shown, the isolation column 22 is located on one side of the sealing component 23 and is connected to the space inside the secondary water tank 2, and is connected to the water inlet pipe portion 25. Specifically, the water inlet pipe portion 25 can be an integrally formed structure with the isolation column 22, and the water inlet pipe portion 25 and the isolation column 22 are connected to the secondary water tank 2 together by bonding. Of course, the water inlet pipe portion 25, the isolation column 22 and the secondary water tank 2 can be integrally formed by a blow molding process.

[0060] In this example, if Figure 1 As shown, the isolation column 22 is located on one side of the sealing component 23 and is connected to the space inside the secondary water tank 2, which is connected to the water inlet pipe part 25, so that the isolation column 22 can replenish water into the secondary water tank 2. At the same time, the water in the isolation column 22 can increase the speed of replenishing the primary water tank 1 through the slow-release rod 3 under the pressure of the water inlet pipe part 25 when replenishing water, thereby ensuring the liquid level of concentrated brine in the primary water tank 1.

[0061] In one embodiment, Figure 1 As shown, the secondary water tank 2 is located on the top of the primary water tank 1, which can facilitate the arrangement of the slow-release rod 3 and simplify the structure.

[0062] In one embodiment, Figure 1 As shown, the drainage part 24 is a siphon, and a first valve 241 is arranged at the water outlet of the siphon; preferably, the highest part of the siphon is lower than the first liquid level sensor 26, and specifically, the siphon is an inverted U-shaped tube; the first valve 241 is a solenoid valve; in this example, the drainage part 24 is a siphon, which has a simple structure, and the first valve 241 is arranged at the water outlet of the siphon, so as to control the opening and closing of the siphon drainage.

[0063] In some embodiments not shown, the drainage portion 24 may also be a pipeline provided with a liquid pump; the liquid pump is connected to the control module, and the liquid is drained by controlling the start of the liquid pump.

[0064] and / or, if Figure 1 As shown, a one-way valve 251 and a second valve 252 are provided in the water inlet pipe 25, and the second valve 252 is connected to the control module; specifically, the one-way valve 251 is an existing product and can be purchased on the market. The setting of the one-way valve 251 can prevent the liquid in the isolation column 22 from flowing back; the second valve 252 is specifically a solenoid valve to realize automatic water replenishment.

[0065] and / or, if Figure 1 As shown, the sealing component 23 includes a sealing male head 231 and a sealing female head 232. The sealing female head 232 is connected to the outer surface of the secondary water tank 2. The sealing female head 232 is annular and is coaxially arranged with the through hole 21. The sealing male head 231 is in a stepped annular shape. The sealing male head 231 is sealed and sleeved on the slow-release rod 3 by means of interference fit or by applying glue. The end face of the large-diameter section of the sealing male head 231 is connected to the outer surface of the primary water tank 1, and the small-diameter section of the sealing male head 231 is sealed and plugged with the sealing female head 232. Specifically, the sealing male head 231 and the sealing female head 232 can be made of rubber. This sealing structure is simple and low in cost.

[0066] In some embodiments not shown, not shown in the drawings, the sealing component 23 includes a sealing male head 231, and there is no need to set a sealing female head 232. The sealing male head 231 is in a stepped ring shape, and the sealing male head 231 is sealed and sleeved on the slow-release rod 3 by interference fit or by applying glue. The end face of the large diameter section of the sealing male head 231 is connected to the outer surface of the first-level water tank 1, and the small diameter section of the sealing male head 231 is directly sealed and plugged with the through hole 21.

[0067] and / or, if Figure 1As shown, the liquid slow-release device also includes a tertiary water tank 5, which is connected to the secondary water tank 2 through a first float valve 6. Preferably, the height of the first float valve 6 is between the water inlet of the drainage part 24 and the second liquid level sensor 27. Specifically, the tertiary water tank 5 is a plastic box, and the first float valve 6 is an existing product that can be purchased on the market.

[0068] In this embodiment, if Figure 1 and Figure 2 As shown, by setting up a three-stage water tank 5, the liquid discharged from the drainage part 24 can be recovered, and when the liquid level in the secondary water tank 2 drops below the first float valve 6, the liquid in the three-stage water tank 5 can flow back to the secondary water tank 2 for continued use, avoiding waste of water resources.

[0069] In one embodiment, Figure 1 As shown, a third liquid level sensor 501 is provided in the third-level water tank 5 , and the third liquid level sensor 501 is connected to the control module. The control module can close the first valve 241 according to the signal of the third liquid level sensor 501 .

[0070] In this example, if Figure 1 and Figure 2 As shown, when the drainage part 24 completes the drainage into the tertiary water tank 5, the first valve 241 is in an open state. When a certain amount of liquid in the secondary water tank 2 is consumed, the water inlet pipe part 25 replenishes the secondary water tank 2. When the liquid level in the secondary water tank 2 exceeds the highest part of the siphon, a certain amount of liquid is discharged into the tertiary water tank 5 through the siphon. When the third sensor detects the liquid level, the controller controls the first valve 241 to close according to the signal of the third sensor. The third sensor is mainly provided to realize automatic control of the closing of the first valve 241.

[0071] In one embodiment, Figure 1 As shown, a partition 11 is provided in the primary water tank 1 to form a salt storage chamber 12 and a brine chamber 13. The salt storage chamber 12 is used to store salt, and the brine chamber 13 is used to store brine. One end of the slow-release rod 3 located outside the secondary water tank 2 is located in the brine chamber 13. A water-permeable hole 111 is provided on the partition 11, and the water-permeable hole 111 connects the salt storage chamber 12 and the brine chamber 13; a second float valve 14 is provided on the top of the brine chamber 13, and a vent hole 28 is provided on the top of the secondary water tank 2, and the second float valve 14 is connected to the vent hole 28;

[0072] Specifically, the salt storage chamber 12 and the brine chamber 13 can be arranged in a stacked manner along the height direction of the primary water tank 1 ( Figure 1), or they can be arranged side by side along the left and right directions of the primary water tank 1. It can be selected and set according to the needs; the diameter of the vent hole 28 is between 0.5mm and 2mm, preferably 1mm, which can be used to prevent the salt block from entering the brine chamber 13.

[0073] In this embodiment, if Figure 1 As shown, by setting up the salt storage chamber 12, the concentration of the concentrated brine in the primary water tank 1 can be guaranteed, so as to ensure the uniformity of the diffusion speed of the concentrated brine in the primary water tank 1 to the secondary water tank 2, thereby ensuring the consistency of the disinfection effect of the disinfectant formed by electrolyzed water; at the same time, the setting of the partition 11 can avoid the occurrence of salt bridges and prevent salt blocks from clogging the isolation column 22, the slow-release rod 3 and other pipelines.

[0074] The overall solution of the present application is fully described below with an embodiment.

The setting of the one-way valve 251 can prevent the liquid in the isolation column 22 from flowing back; the second valve 252 is specifically a solenoid valve to realize automatic water replenishment.

[0087] Specifically, Figure 1 As shown, the sealing component 23 includes a sealing male head 231 and a sealing female head 232.

The sealing male head 231 is in a stepped annular shape. The sealing male head 231 is sealed and sleeved on the slow-release rod 3 by means of interference fit or by applying glue. The end face of the large-diameter section of the sealing male head 231 is connected to the outer surface of the primary water tank 1, and the small-diameter section of the sealing male head 231 is sealed and plugged with the sealing female head 232. Specifically, the sealing male head 231 and the sealing female head 232 can be made of rubber. This sealing structure is simple and low in cost.

Preferably, the height of the first float valve 6 is between the water inlet of the drainage part 24 and the second liquid level sensor 27. Specifically, the tertiary water tank 5 is a plastic box, and the first float valve 6 is an existing product that can be purchased on the market.

[0089] More specifically, Figure 1 As shown, a third liquid level sensor 501 is provided in the third-level water tank 5 , and the third liquid level sensor 501 is connected to the control module. The control module can close the first valve 241 according to the signal of the third liquid level sensor 501 .

[0090] Specifically, Figure 1 As shown, a partition 11 is provided in the primary water tank 1 to form a salt storage chamber 12 and a brine chamber 13. The salt storage chamber 12 is used to store salt, and the brine chamber 13 is used to store brine. One end of the slow-release rod 3 located outside the secondary water tank 2 is located in the brine chamber 13. A water-permeable hole 111 is provided on the partition 11, and the water-permeable hole 111 connects the salt storage chamber 12 and the brine chamber 13; a second float valve 14 is provided on the top of the brine chamber 13, and a vent hole 28 is provided on the top of the secondary water tank 2, and the second float valve 14 is connected to the vent hole 28;

[0092] Specifically, Figure 1 As shown, the secondary water tank 2 is located on the top of the primary water tank 1, which can facilitate the arrangement of the slow-release rod 3 and simplify the structure.

[0093] In the specific use process, such as Figure 2 As shown, when the liquid level in the secondary water tank 2 is lower than the second sensor, the second valve 252 on the water inlet pipe portion 25 is opened to replenish liquid into the isolation column 22.

[0094] Liquid is replenished into the secondary water tank 2 through the top opening of the isolation column 22. When the liquid level in the secondary water tank 2 is higher than the first float valve 6, the first float valve 6 is closed; when the liquid level rises above the isolation column 22, the primary water tank 1 and the secondary water tank 2 are connected, and the concentrated brine in the primary water tank 1 begins to diffuse into the primary water tank 1; when the liquid level continues to rise and is higher than the top of the siphon, the liquid in the secondary water tank 2 enters the tertiary water tank 5 through the siphon, and when the third liquid level sensor 501 detects the liquid level, the first valve 241 is closed; the liquid level in the secondary water tank 2 continues to rise, and when the first liquid level sensor detects the liquid level, the second valve 252 on the water inlet pipe 25 is closed.

[0095] When the water inlet pipe 25 replenishes water into the secondary water tank 2 through the isolation column 22, the water in the isolation column 22 replenishes water into the primary water tank 1 through the slow-release rod 3. When the liquid in the primary water tank 1 is full, the second float valve 14 is closed.

[0096] When the concentration sensor 4 detects that the chloride ion concentration in the secondary water tank 2 reaches the set value, the first valve 241 opens, and the liquid in the secondary water tank 2 is discharged into the tertiary water tank 5 through the siphon, cutting off the liquid connection between the primary water tank 1 and the secondary water tank 2.

[0097] When the liquid consumption in the secondary water tank 2 drops below the outlet of the first float valve 6 , the first float valve 6 opens, and the liquid in the tertiary water tank 5 is replenished into the secondary water tank 2 .

[0098] When the liquid in the secondary water tank 2 is lower than the second liquid level sensor 27, the second valve 252 on the water inlet pipe 25 is reopened to enter the next liquid replenishment cycle.
