Electrolytic salting device, disinfection equipment and electrolytic salting control method

Abstract

The present invention belongs to the technical field of electrolytic disinfection, and discloses an electrolytic salting device, disinfection equipment and electrolytic salting control method. The salting device includes a liquid storage container, a salt warehouse and at least one water-absorbing slow-release component. The water-absorbing slow-release component has a first end and a second end. The first end extends into the salt warehouse and contacts the salt particles in the salt warehouse, and the second end extends into the liquid storage container and contacts the liquid in the liquid storage container. After the second end contacts the liquid, the liquid moves toward the first end under capillary action, and the soaked first end dissolves the salt particles around it. Based on the principle that the high-concentration area spontaneously diffuses to the low-concentration area, the high-concentration salt solution at the first end spontaneously diffuses to the second end, and gradually releases the salt into the liquid storage container. Since the salt can be gradually released from the salt warehouse to the liquid storage container only through the water-absorbing slow-release component, it is helpful to reduce the volume, save space and cost, improve the utilization rate of salt, eliminate the defect of salt blocking the pipeline, and reduce the risk of excessive chloride ion concentration in the liquid.

Description

Technical Field

[0001] The present invention relates to the technical field of electrolytic disinfection, and in particular to an electrolytic salt adding device, disinfection equipment and an electrolytic salt adding control method. Background Art

[0002] Disinfection equipment that uses electrolytic water disinfection technology relies on the electrolysis of chloride ions in water to produce a solution with a disinfecting effect. However, there are significant differences in the chloride ion content of tap water in different regions, and the chloride ion concentration in most regions is relatively low. If tap water is directly used to prepare disinfectant through electrolysis, it is difficult to meet the expected standards. Some existing disinfection equipment is equipped with a salt warehouse, which stores salt particles. By actively replenishing water to dissolve some of the salt particles, a saturated sodium chloride solution is formed, which is then pumped into the water tank by a water pump to increase the chloride ion concentration in the water tank. The electrolysis module uses electrodes to electrolyze the sodium chloride solution in the water tank to produce hypochlorous acid disinfectant.

[0003] The prior art has the following defects: in the scheme of pumping sodium chloride solution into the water tank by a water pump, the disinfection equipment needs to reserve the installation position of the water pump and other components, which takes up a large space and increases the overall cost. Moreover, there may be a large amount of undissolved salt in the sodium chloride solution to be extracted by the water pump. On the one hand, the undissolved salt increases the risk of pipeline blockage, and on the other hand, it also causes the waste of salt, reduces the utilization rate of the sodium chloride solution, and causes unnecessary waste. In addition, the method of pumping sodium chloride solution may cause the chloride ion concentration in the water tank and the hypochlorous acid solution concentration after electrolysis to be too high, which has certain hazards to the human body and the equipment itself.

[0004] Therefore, there is an urgent need for an electrolytic salt adding device, a disinfection device and an electrolytic salt adding control method to solve the above-mentioned problems existing in the prior art. Summary of the invention

[0035] Beneficial effects of the present invention:

[0036] The present invention provides an electrolytic salting device and a disinfection device including the electrolytic salting device. A water-absorbing slow-release component is provided. When the second end of the water-absorbing slow-release component contacts the liquid in a liquid storage container, the liquid gradually moves toward the first end along the water-absorbing slow-release component under capillary action, so that the first end of the water-absorbing slow-release component is soaked. Since the first end extends into the interior of the salt bin and contacts the salt particles in the salt bin, the soaked first end will dissolve the salt particles around it, so that the liquid absorbed by the first end becomes a high-concentration salt solution, while the liquid in the liquid storage container is a low-concentration solution, that is, the first end is a high-concentration area, and the second end is a low-concentration area. Based on the principle that the high-concentration area will spontaneously diffuse to the low-concentration area, the high-concentration salt solution at the first end will spontaneously diffuse to the second end gradually, so as to gradually release the salt into the liquid storage container, so that the chloride ion concentration in the liquid in the liquid storage container increases, so that the electrolysis module can electrolyze the liquid into a disinfectant of suitable concentration. The salt adding device can realize the gradual release of salt from the salt bin into the liquid storage container only by setting a water-absorbing slow-release component, without adding components such as pumps, which helps to reduce the volume of the device, thereby saving the occupied space of the entire disinfection equipment, and reducing the number of components to reduce production costs. Moreover, the salt particles can gradually diffuse from the first end of the water-absorbing slow-release component to the second end only after they are dissolved, without the risk of clogging structures such as pipelines, and can also reduce the waste of salt particles and improve the utilization rate of salt particles in the salt bin. In addition, by gradually releasing salt through the water-absorbing slow-release component, it is possible to avoid adding too much salt into the liquid storage container in a short period of time, and to avoid the excessive concentration of the disinfectant generated after electrolysis causing harm to the human body or equipment.

[0037] The present invention also provides an electrolysis salt addition control method, the obtained electrolysis parameters can reflect the chloride ion concentration in the liquid in the liquid storage container, and the electrolysis time is determined according to the obtained electrolysis parameters, so as to prepare a disinfectant of appropriate concentration, so as to avoid the electrolysis time being too long resulting in too high a concentration of the disinfectant or the electrolysis time being too short resulting in the concentration of the disinfectant failing to meet the standard. At the same time, if the concentration of chloride ions in the liquid in the liquid storage container is too low, it can be known through the obtained electrolysis parameters, and then a prompt signal indicating the lack of salt in the salt bin is issued, so as to promptly remind the user to add salt particles to the salt bin, and ensure that the disinfectant meeting the concentration requirements can be continuously and uninterruptedly prepared.

[0062] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0063] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0064] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0065] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0066] In this embodiment, the term "and / or" is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in the present invention generally indicates that the associated objects before and after are in an "or" relationship.

[0067] In the embodiments of the present invention, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments.

[0068] The embodiment of the present application provides an electrolytic salt-adding device 100, which can reduce the occupied space, save costs, improve the utilization rate of salt, eliminate the defect of pipeline blockage caused by a large number of undissolved salt particles, and to a certain extent avoid the prepared disinfectant concentration exceeding the standard and endangering the human body or the component materials in contact with the disinfectant.

[0069] like Figure 1 and Figure 2 As shown, the electrolysis salting device 100 provided in the embodiment of the present application includes a liquid storage container 1, a salt bin 2, and a water-absorbing slow-release component 3. The liquid storage container 1 is used to store liquid, the salt bin 2 is used to store salt particles, and the water-absorbing slow-release component 3 is used to introduce the salt in the salt bin 2 into the liquid storage container 1. The liquid in the liquid storage container 1 may initially be tap water, and the salt in the salt bin 2 becomes a salt solution (sodium chloride solution) after being introduced. If the liquid is electrolyzed in the liquid storage container 1, hypochlorous acid is generated after the liquid is electrolyzed, so that the liquid in the liquid storage container 1 is prepared into a disinfectant.

[0070] At least one water-absorbing slow-release component 3 is provided, and at least one means that there can be two or more than two. The water-absorbing slow-release component 3 has a first end 31 and a second end 32. The first end 31 extends into the salt bin 2 and contacts the salt particles in the salt bin 2, and the second end 32 extends into the liquid storage container 1 and contacts the liquid in the liquid storage container 1.

[0071] By setting the water-absorbing slow-release member 3, when the second end 32 of the water-absorbing slow-release member 3 contacts the liquid in the liquid storage container 1, the liquid gradually moves toward the first end 31 along the water-absorbing slow-release member 3 under the capillary action, so that the first end 31 of the water-absorbing slow-release member 3 is soaked. Since the first end 31 extends into the salt bin 2 and contacts the salt particles in the salt bin 2, the soaked first end 31 will dissolve the salt particles around it, so that the liquid absorbed by the first end 31 becomes a high-concentration salt solution, while the liquid in the liquid storage container 1 is a low-concentration solution, that is, the first end 31 is a high-concentration area, and the second end 32 is a low-concentration area. Based on the principle that the high-concentration area will spontaneously diffuse to the low-concentration area, the high-concentration salt solution at the first end 31 will spontaneously diffuse to the second end 32 gradually, so as to gradually release the salt into the liquid storage container 1, so that the chloride ion concentration in the liquid in the liquid storage container 1 increases, so that the electrolysis module 200 can electrolyze the liquid into a disinfectant of appropriate concentration.

[0072] The salt adding device can realize the gradual release of salt from the salt bin 2 to the liquid storage container 1 only by setting the water absorbing slow-release component 3, without adding components such as pumps, which helps to reduce the volume of the device, thereby saving the occupied space of the entire disinfection equipment, and reducing the number of components to reduce production costs. Moreover, the salt particles can gradually diffuse from the first end 31 of the water absorbing slow-release component 3 to the second end 32 after being dissolved, without the risk of clogging the structure such as the pipeline, and can also reduce the waste of salt particles and improve the utilization rate of the salt particles in the salt bin 2. In addition, by gradually releasing the salt through the water absorbing slow-release component 3, it can be avoided that too much salt is added to the liquid storage container 1 in a short time, and the concentration of the disinfectant generated after electrolysis is too high to cause harm to the human body or equipment.

[0073] The liquid in the liquid storage container 1 can be directly electrolyzed to prepare a disinfectant. Furthermore, the liquid storage container 1 can be connected to an atomizing spray device to achieve disinfection by spraying the disinfectant. Alternatively, the saline solution in the liquid storage container 1 can be pumped out by a water pump, mixed with tap water, and then electrolyzed to prepare a disinfectant with a slightly lower concentration. The specific method of use can be adaptively set according to factors such as the concentration of the disinfectant to be prepared.

[0074] like Figure 1 and Figure 2 As shown, the salt bin 2 is arranged above the liquid storage container 1 at intervals, so that the high-concentration salt solution absorbed by the first end 31 can be more smoothly diffused to the second end 32. That is, the upper end (first end 31) of the water-absorbing slow-release component 3 is located in the salt bin 2, and the lower end (second end 32) is located in the liquid storage container 1. Of course, the salt bin 2 and the liquid storage container 1 can also be arranged at intervals in the horizontal direction, and the salt content of the first end 31 of the water-absorbing slow-release component 3 can also be diffused to the second end 32, and then released into the liquid storage container 1.

[0075] When adding salt grains into the salt bin 2, it is preferred to add the salt grains until they completely cover the first end 31 of the water-absorbing slow-release component 3, so that there is a sufficient contact area between the first end 31 and the salt grains, thereby improving the salt release efficiency and avoiding waste of the water-absorbing slow-release component 3 so that it can be fully utilized. Of course, the salt grains may only cover part of the first end 31, as long as the first end 31 can contact with the salt grains to dissolve the salt grains.

[0076] In some embodiments of the present application, the first end 31 of the water-absorbing slow-release component 3 is at least partially bent and extended to increase the length of the first end 31 buried in the salt particles, so that there is a sufficient contact area between the first end 31 and the salt particles, thereby improving the efficiency of dissolving the salt particles and the efficiency of diffusing the salt to the second end 32.

[0077] Optionally, the first end 31 of the water-absorbing slow-release member 3 includes a water-absorbing rope and / or a water-absorbing plate and / or a water-absorbing rod. That is, the first end 31 can be a water-absorbing rope, a water-absorbing plate or a water-absorbing rod, or a combination of any two or three of the water-absorbing rope, the water-absorbing plate and the water-absorbing rod. Of course, the first end 31 can also be other shapes and structures, which are not limited here.

[0078] Further, the second end 32 of the water-absorbing slow-release member 3 includes a water-absorbing rope and / or a water-absorbing plate and / or a water-absorbing rod. That is, the second end 32 can be a water-absorbing rope, a water-absorbing plate or a water-absorbing rod, or a combination of any two or three of the water-absorbing rope, the water-absorbing plate and the water-absorbing rod. Of course, the second end 32 can also be other shapes and structures, which are not limited here.

[0079] In some embodiments, the material of the water-absorbing slow-release component 3 can be a cotton material with good water absorption performance. Exemplarily, the water-absorbing slow-release component 3 is a cotton rope, a cotton swab, or a cotton board (which can be pressed into shape) made of cotton material.

[0080] In other embodiments, the material of the water-absorbing sustained-release component 3 may also be a highly water-absorbent resin, such as starch-grafted acrylates, grafted acrylamide, highly substituted cross-linked carboxymethyl cellulose, etc., but is not limited thereto.

[0081] The structure of the first end 31 is listed below with reference to several specific embodiments.

[0082] like Figure 1 , Figure 2 as well as Figure 3 FIG. 1 is a schematic diagram of an electrolytic salt adding device 100 provided in a first embodiment. In this embodiment, the first end 31 at least partially extends in a spiral, which effectively increases the extension length of the first end 31 in the salt bin 2, thereby improving the salt dissolving efficiency and the salt slow release efficiency.

[0083] The water-absorbing slow-release component 3 in this embodiment is an integrated structure, for example, made of a whole cotton rope, one end of which is spirally coiled to form a first end 31, and placed in the salt bin 2. The spirally coiled portion of the cotton rope can be fixed by sewing with cotton thread, which does not affect the overall water absorption and salt dissolving efficiency of the first end 31, or can also be fixed by glue dispensing.

[0084] like Figure 1 and Figure 2 As shown, the salt warehouse 2 includes a first warehouse body 21 and a second warehouse body 22, the second warehouse body 22 is connected to the lower end of the first warehouse body 21, and the bottom of the second warehouse body 22 is provided with a through hole 20 for penetrating the water-absorbing slow-release component 3. The first warehouse body 21 is cylindrical, and the second warehouse body 22 is conical. The conical second warehouse body 22 can achieve a height that completely covers the water-absorbing slow-release component 3 by adding a small amount of salt, saving the amount of salt.

[0085] Optionally, the spiral radius of the first end 31 gradually increases from bottom to top, so that the first end 31 is spirally wound into a structure that matches the conical second bin body 22, and the internal space of the first end 31 is increased as much as possible to make it fully contact with the salt particles. Of course, the spiral radius of the first end 31 can also remain unchanged, or gradually decrease from bottom to top.

[0086] Optionally, the first warehouse body 21 and the second warehouse body 22 are fixedly connected, and the entire salt warehouse 2 is an integrated structure, which is easy to manufacture and reduces the assembly process.

[0087] Of course, the first warehouse body 21 and the second warehouse body 22 can also be made separately and detachably connected together, so as to facilitate the placement of the water-absorbing slow-release component 3 in the salt warehouse 2 and reduce the difficulty of assembly. It is also convenient to replace the water-absorbing slow-release component 3 later. Exemplarily, the first warehouse body 21 and the second warehouse body 22 are threadedly connected, and the water-absorbing slow-release component 3 can be placed in the second warehouse body 22 first, and the second end 32 is extended through the through hole 20, and then the first warehouse body 21 is screwed to the second warehouse body 22.

[0088] It should be noted that the first end 31 can be completely spirally extended in the salt warehouse 2, such as Figure 2 and Figure 3 As shown; alternatively, the first end 31 may also extend in a spiral shape in only a portion, for example, in a spiral shape in a portion and in a serpentine shape in another portion.

[0089] like Figure 4 , Figure 5 as well as Figure 6, which is a schematic diagram of an electrolytic salt-adding device 100 provided in a second embodiment. In this embodiment, a first knotted portion 311 is provided at the first end 31, and for example, the water-absorbing slow-release component 3 is a cotton rope, and the cotton rope is knotted to form the first knotted portion 311, which can increase the contact area between the first end 31 and the salt particles, improve the salt dissolving efficiency and the salt slow-release efficiency, and on the other hand, the first knotted portion 311 can be stopped in the salt bin 2 to prevent the water-absorbing slow-release component 3 from falling through the perforation 20 of the salt bin 2.

[0090] The water-absorbing slow-release component 3 in this embodiment is an integrated structure, for example, made of a whole cotton rope, one end of which is knotted to form at least one first knotted portion 311, and placed in the salt warehouse 2. The knotted cotton rope does not need to be fixed in shape by other means, and is easy to manufacture.

[0091] like Figure 7 , Figure 8 as well as Fig. 9 , which is a schematic diagram of an electrolytic salt-adding device 100 provided in a third embodiment. In this embodiment, the first end 31 of the water-absorbing slow-release member 3 includes a first water-absorbing portion 312 and a second water-absorbing portion 313 coiled on the first water-absorbing portion 312. By coiling the second water-absorbing portion 313 on the first water-absorbing portion 312, the contact area between the first end 31 and the salt particles can be increased, and the water-absorbing slow-release member 3 can be prevented from falling through the perforation 20 of the salt bin 2.

[0092] The water-absorbing slow-release member 3 in this embodiment is a split structure, for example, two cotton ropes, the upper end of one of the cotton ropes is the first water-absorbing part 312, and the lower end extends into the liquid storage container 1, and the other cotton rope is coiled on the first water-absorbing part 312, which can be fixed by knotting, or sewing with cotton thread, or by glue, as long as the first water-absorbing part 312 and the second water-absorbing part 313 are in full contact, so that the first water-absorbing part 312 guides the liquid to the second water-absorbing part 313. The winding length of the second water-absorbing part 313 on the first water-absorbing part 312 can be determined according to design requirements.

[0093] like Figures 10 to 14 , which is a schematic diagram of an electrolytic salt-adding device 100 provided in a fourth embodiment. In this embodiment, the first end 31 of the water-absorbing slow-release component 3 includes a water-absorbing plate, and the plate surface of the water-absorbing plate contacts the salt particles, so that there is a sufficient contact area between the first end 31 and the salt particles, and water is fully absorbed to dissolve the salt particles, thereby improving the efficiency of slow-release salt.

[0094] In some embodiments, the water absorption plate can be a whole plate body adapted to the cross section of the salt warehouse 2. Fig.10 and Fig.11 The first warehouse body 21 and the second warehouse body 22 of the salt warehouse 2 are both cylindrical barrels, and the water absorption plate can be a circular plate.

[0095] In other embodiments, the water absorbing plate can be a split structure. Fig.12 , Fig.13 as well as Fig.14 The water absorbing plate includes a first plate body 314 and a second plate body 315 which are detachably connected. The first plate body 314 is connected to the second end 32. The second plate body 315 is provided with a connecting mounting groove 3151 and a through hole 3152. The mounting groove 3151 and the through hole 3152 form a stepped hole structure. The mounting groove 3151 is engaged with the first plate body 314 to locate the relative position of the first plate body 314 and the second plate body 315. The salt particles in the salt bin 2 can fall onto the upper surface of the first plate body 314 through the through hole 3152. The contact area between the water absorbing plate and the salt particles can be changed by the detachable first plate body 314 and the second plate body 315. When only the first plate body 314 is placed in the salt bin 2, the contact area between the first end 31 and the salt particles is smaller. When the first plate body 314 and the second plate body 315 are combined and placed in the salt bin 2, the contact area between the first end 31 and the salt particles is larger. The size of the contact area affects the release speed of the salt. The larger the contact area, the faster the release speed. The combination can be adaptively adjusted according to needs, with higher flexibility.

[0096] See also Fig.13 and Fig.14 The first plate 314 and the second plate 315 are both provided with a plurality of connection holes 3153 corresponding to each other. The first plate 314 and the second plate 315 can be fixed by using the positioning member 316 to penetrate the connection holes 3153 connecting the two, so that the first plate 314 and the second plate 315 can be in good contact with each other, so that the second plate 315 can absorb the moisture of the first plate 314, thereby fully dissolving the salt in contact with the second plate 315 and the first plate 314. The positioning member 316 can be a compacted cotton swab with a high water absorption capacity, and will not affect the water absorption effect of the water absorption plate.

[0097] The water absorbing slow-release member 3 provided as the fifth embodiment has its first end 31 at least partially extending in a serpentine shape. That is, the portion of the water absorbing slow-release member 3 located in the salt bin 2 may extend in a serpentine shape, or a portion may extend in a serpentine shape and the other portion may be provided with a first knotted portion 311 .

[0098] It can be understood that the shape structure of the first end 31 can be a combination of any two or more of the above embodiments, which will not be listed here one by one.

[0099] In some embodiments, Figure 3 , Figure 5 , Figure 8 as well as Fig.11 As shown, the second end 32 of the water absorbing slow-release component 3 does not have any overlapping parts, and does not require knotting or spiral winding and fixing during manufacturing, and can be directly extended into the liquid storage container 1.

[0100] In other embodiments, similar to the first end 31, a knotted or spirally wound or serpentine wound and fixed manner can be adopted to increase the contact area between the second end 32 and the liquid in the liquid storage container 1, thereby increasing the salt release rate.

[0101] Exemplarily, the second end 32 is at least partially bent and extended. For example, the second end 32 is at least partially spirally extended or serpentinely extended; and / or, the second end 32 is provided with a second knotted portion; and / or, the second end 32 includes a third water absorbing portion and a fourth water absorbing portion coiled on the third water absorbing portion. Further, the second end 32 can also be as follows: Fig.12 The absorbent plate shown.

[0102] The shape and structure of the second end 32 can be referred to Figures 1 to 14 The shape and structure of the first end 31 are shown and will not be described in detail here.

[0103] It should be noted that factors such as the thickness, tightness, length of the water-absorbing slow-release component 3 extending into the liquid in the liquid storage container 1, and length of the component extending into the salt bin 2 all affect the release rate of salt to a certain extent. The above factors can be adaptively adjusted according to the concentration of the disinfectant to be prepared.

[0104] In the embodiment of the present application, a sealing structure is provided between the inner wall of the perforation 20 and the water absorbing slow-release member 3 to ensure the sealing of the bottom of the salt bin 2 and prevent the leakage of salt particles. For example, the sealing structure may include a sealing ring sleeved on the water absorbing slow-release member 3, or include a glue layer formed by gluing between the inner wall of the perforation 20 and the water absorbing slow-release member 3.

[0105] This embodiment also provides a disinfection device, including an electrolysis module 200 and the electrolysis salt adding device 100 as described above, wherein the electrolysis module 200 and the sodium chloride solution in the liquid storage container 1 form an electrolysis circuit for electrolyzing the sodium chloride solution in the liquid storage container 1 to prepare a disinfectant. The structure of the electrolysis module 200 and the principle of electrolyzing the sodium chloride solution are existing mature technologies and will not be described in detail here.

[0106] The disinfection device can be used in bathroom equipment for disinfection, where the bathroom equipment includes but is not limited to toilets, hardware faucets, bathroom cabinets, etc., or the disinfection device can also be used in places such as swimming pools to disinfect the water in the swimming pool. It can be understood that the disinfection device provided in this embodiment can be used in places where disinfection is required, not limited to the above-mentioned bathroom equipment and swimming pool equipment.

[0107] like Fig.15As shown, the disinfection device also includes a detection module 300 and a prompt module 400 that are communicatively connected. The detection module 300 is used to detect the voltage value of the electrolysis circuit and / or the current value of the electrolysis circuit and / or the conductivity of the liquid in the liquid storage container 1. The prompt module 400 is used to send a prompt signal when the detection value of the detection module 300 exceeds the set threshold. The voltage value, the current value of the electrolysis circuit and the conductivity of the liquid in the liquid storage container 1 can all reflect the chloride ion concentration of the disinfectant. For example, when the detection value of the detection module 300 exceeds the set threshold, it indicates that the chloride ion concentration is too low and the concentration of the disinfectant does not meet the standard. The reason is usually caused by insufficient salt particles in the salt warehouse 2. At this time, the control prompt module 400 sends a salt shortage prompt signal so that the user can add salt to the salt warehouse 2 in time.

[0108] The detection module 300 may include a voltage detection module 300, a current detection module 300 or a conductivity detection module 300. The voltage detection module 300 and the current detection module 300 are usually integrated on the control board of the electrolysis module 200, and no other detection modules 300 need to be additionally provided.

[0109] Furthermore, the disinfection device includes a control module 500, such as a PLC controller, which is communicatively connected to the electrolysis module 200, the prompt module 400 and the detection module 300. The control module 500 can control the opening and closing of the electrolysis module 200, obtain the detection value of the detection module 300, and control the prompt module 400 to send a prompt signal according to the detection value.

[0110] Exemplarily, the prompt module 400 includes a warning light and / or a buzzer and / or a display screen capable of displaying prompt information.

[0111] Furthermore, the disinfection device may further include a salt adding module 600, which is connected to the control module 500 in communication and stores salt particles, and the control module 500 may control the salt adding module 600 to add salt particles into the salt bin 2. The control of the salt adding module 600 may be achieved by the user turning a knob on the device, pressing a button, or performing a touch operation. Of course, after the salt shortage prompt signal is issued, salt may also be added to the salt bin 2 manually.

[0112] like Fig.16 As shown, this embodiment also provides an electrolysis salt addition control method, which is applied to the disinfection equipment as described above, and the method includes:

[0113] S0, control the electrolysis module 200 to start;

[0114] S1. Obtaining electrolysis parameters; wherein the electrolysis parameters include the voltage value of the electrolysis circuit or the current value of the electrolysis circuit and / or the conductivity of the liquid in the liquid storage container 1.

[0115] Specifically, the voltage value may be detected by the voltage detection module 300 , the current value may be detected by the current detection module 300 , and the current value may be detected by the conductivity detection module 300 .

[0116] S2. Determine the electrolysis time according to the electrolysis parameters or send a prompt signal indicating that there is a lack of salt in the salt bin 2; wherein the electrolysis time is the time it takes for the electrolysis module 200 to electrolyze the liquid in the liquid storage container 1.

[0117] It can be understood that the acquisition of electrolysis parameters is performed periodically, and after a determined electrolysis duration has elapsed, the electrolysis parameters are re-acquired to determine the electrolysis duration of the next stage.

[0118] The electrolysis and salting control method provided in the embodiment of the present application can obtain electrolysis parameters that reflect the chloride ion concentration in the liquid in the liquid storage container 1. The electrolysis time is determined according to the obtained electrolysis parameters, so as to prepare a disinfectant of appropriate concentration, and avoid the electrolysis time being too long, resulting in too high a concentration of the disinfectant, or the electrolysis time being too short, resulting in the concentration of the disinfectant failing to meet the standard. At the same time, if the concentration of chloride ions in the liquid in the liquid storage container 1 is too low, it can be known through the obtained electrolysis parameters, and then a prompt signal indicating that there is a lack of salt in the salt bin 2 is issued, so that the user can be reminded in time to add salt particles to the salt bin 2, ensuring that the disinfectant that meets the concentration requirements can be continuously and uninterruptedly prepared.

[0119] Step S2 includes:

[0120] If the electrolysis parameter is within the first preset range, the electrolysis duration is determined to be the first preset duration;

[0121] If the electrolysis parameter is within the second preset range, the electrolysis duration is determined to be the second preset duration;

[0122] If the electrolysis parameter is within the third preset range, the disinfection device is controlled to send a prompt signal;

[0123] Among them, the first preset range, the second preset range, and the third preset range increase or decrease in sequence; the first preset time length is not equal to the second preset time length.

[0124] The specific execution process of step S2 is described below through several specific embodiments.

[0125] As a first embodiment of the electrolysis salt addition control method, after the electrolysis module 200 is started, the control module 500 controls the current in the electrolysis circuit to be constant (i.e., constant current electrolysis mode). The electrolysis parameters include the voltage value of the electrolysis circuit detected by the voltage detection module 300, and step S2 specifically includes:

[0126] If the voltage value is less than or equal to the first voltage threshold a1, the electrolysis time is determined to be the first time t1 (i.e. the first preset time);

[0127] If the voltage value is greater than the first voltage threshold a1 and less than the second voltage threshold a2, the electrolysis time is determined to be the second time t2 (i.e., the second preset time); wherein the first time t1 is less than the second time t2; and the first voltage threshold a1 is less than the second voltage threshold a2;

[0128] If the voltage value is greater than or equal to the second voltage threshold a2, the prompt module 400 of the control disinfection equipment sends a prompt signal.

[0129] The first preset range is less than or equal to the first voltage threshold a1, the second preset range is greater than the first voltage threshold a1 and less than the second voltage threshold a2, and the third preset range is greater than or equal to the second voltage threshold a2.

[0130] The higher the chloride ion concentration in the disinfectant, the stronger the conductivity and the smaller the resistance. Based on Ohm's theorem, in the constant current electrolysis mode, the higher the chloride ion concentration, the smaller the voltage. Therefore, the larger the voltage value obtained, the lower the chloride ion concentration. If the voltage value is between a1 and a2, the electrolysis time can be determined as a slightly longer second time t2 to ensure that a disinfectant that meets the concentration requirements can be prepared. When the voltage value exceeds a2 (a2 is the above-mentioned set threshold), it indicates that there is a lack of salt in the salt warehouse 2. At this time, the prompt module 400 can be controlled to send a salt shortage prompt signal.

[0131] As a second embodiment of the electrolysis salt addition control method, after the electrolysis module 200 is started, the control module 500 controls the voltage in the electrolysis circuit to be constant (i.e., constant voltage electrolysis mode). The electrolysis parameters include the current value of the electrolysis circuit detected by the current detection module 300, and step S2 specifically includes:

[0132] If the current value is less than or equal to the first current threshold b1, the disinfection device is controlled to send a prompt signal;

[0133] If the current value is greater than the first current threshold b1 and less than the second current threshold b2, the electrolysis time is determined to be the third time t3 (i.e. the second preset time); wherein the first current threshold b1 is less than the second current threshold b2;

[0134] If the current value is greater than or equal to the second current threshold b2, the electrolysis time is determined to be the fourth time t4 (ie, the first preset time); wherein the third time t3 is greater than the fourth time t4.

[0135] The first preset range is greater than or equal to the second current threshold b2, the second preset range is greater than the first current threshold b1 and less than the second current threshold b2, and the third preset range is less than or equal to the first current threshold b1.

[0136] In the constant voltage electrolysis mode, the higher the chloride ion concentration in the disinfectant, the greater the current. When the current value is smaller, it indicates that the chloride ion concentration is lower. If the current value is between b1 and b2, the electrolysis time can be determined as a slightly longer third time t3. When the current value is less than b1 (b1 is the above-mentioned set threshold), it indicates that there is a lack of salt in the salt warehouse 2. At this time, the prompt module 400 can be controlled to send a salt shortage prompt signal.

[0137] As a third embodiment of the electrolysis salt addition control method, the electrolysis parameter includes the conductivity of the liquid in the liquid storage container 1. The higher the chloride ion concentration in the disinfectant, the higher the conductivity. Step S2 specifically includes:

[0138] If the conductivity is less than or equal to the first conductivity threshold c1 (i.e. the set threshold mentioned above), the disinfection device is controlled to send a prompt signal;

[0139] If the conductivity is greater than the first conductivity threshold c1 and less than the second conductivity threshold c2, the electrolysis time is determined to be the fifth time t5; wherein the first conductivity threshold c1 is less than the second conductivity threshold c2;

[0140] If the conductivity is greater than or equal to the second conductivity threshold c2, the electrolysis time is determined to be the sixth time t6; wherein the fifth time t5 is greater than the sixth time t6.

[0141] The above-mentioned first preset range is a range greater than or equal to the second conductivity threshold c2, and the first preset time length is the sixth time length t6; the second preset range is a range greater than the first conductivity threshold c1 and less than the second conductivity threshold c2, and the second preset time length is the fifth time length t5; the third preset range is a range less than or equal to the first conductivity threshold c1.

[0142] The electrolysis salt addition control method provided in the embodiment of the present application can stabilize the concentration of the disinfectant prepared by electrolysis at around the set concentration by obtaining electrolysis parameters to determine the electrolysis time and issuing a salt shortage prompt, thereby achieving a constant hypochlorous acid mode and issuing a salt shortage prompt in a timely manner.
