Description

Technical Field

[0001] The invention relates to the technical field of water treatment equipment, and in particular to a salt absorption component and a water heater. Background Art

[0002] A water heater is a device that uses various physical principles to increase the temperature of cold water into hot water within a certain period of time. According to different principles, it can be divided into electric water heaters, gas water heaters, solar water heaters, etc. At present, with the improvement of people's living standards, people's requirements for daily water are getting higher and higher. Due to factors such as geography, the water quality in various parts of the country is uneven, and the water quality resources vary greatly. The water quality in most areas is hard. Long-term use of hard water will make people's skin dry, rough, and age quickly. Therefore, people's demand for soft water continues to rise. Soft water contains no or less soluble calcium and magnesium compounds. Using soft water can effectively inhibit fungi, delay skin aging, and prevent scaling of heated water. It is beneficial to life.

[0003] Based on this, a soft water heater that integrates a water softener component with a water heater component has appeared on the market, which removes calcium and magnesium ions in the water through a soft water resin to reduce the hardness of the water. When the soft water resin is used to a certain extent, it will become ineffective and needs to be regenerated with saturated salt water so that the soft water resin can be used again.

[0004] When regenerating the water softening resin, it is necessary to form saturated brine in the salt box, and then pump the saturated brine in the salt box into the water softening component to react with the water softening resin to regenerate it. Since the control mechanism in the salt box can automatically stop the water intake when the water level reaches a certain height, due to its structural factors, when regenerating the water softening resin, the saturated brine in the salt box cannot be completely sucked dry. There will be a considerable amount of saturated brine in the salt box, and the salt box cannot form a real dry salt box, which will cause salt climbing in the salt box. Summary of the invention

[0030] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0033] See also Figure 2-5 The present invention provides a salt absorption component, including: a salt box 1, a salt valve 2 and a water pipe 3. The salt valve 2 is arranged in the salt box 1, and the salt valve 2 is connected to the water pipe 3 to discharge water, and a valve is arranged on the water pipe 3. A salt cavity 21 with a large inner diameter and a tube cavity 22 with a small inner diameter are provided inside the salt valve 2. One end of the salt cavity 21 is connected to the water pipe 3, and the other end of the salt cavity 21 is connected to the tube cavity 22. The tube cavity 22 is arranged on one side of the salt cavity 21 and extends downward to abut against the inner bottom wall of the salt box 1.

[0034] The salt box 1 is used to form saturated salt water, and the salt valve 2 is used to absorb the saturated salt water in the salt box 1 and transport it to the water pipe 3. The water pipe 3 is connected to the soft water component so that the salt valve 2 can be used to absorb the saturated salt water in the salt box 1 and transport it to the soft water component after the valve is opened.

[0035] The salt absorption components of the prior art have two major defects. First, the saturated salt water in the salt box 1 cannot be completely absorbed. There will be a considerable amount of saturated salt water in the salt box 1. The salt box 1 cannot form a real dry salt box 1, which will cause salt climbing in the salt box 1. Second, the existing salt absorption components are all equipped with power structures such as power pumps to provide driving force for absorbing saturated salt water, which not only increases the cost and energy consumption, but also the power pump has high requirements for use conditions. It is necessary to ensure normal operation and avoid working conditions such as air absorption, otherwise it is easy to be damaged. Once the power pump is damaged, it cannot continue to absorb saturated salt water, which not only affects the regeneration of the soft water resin, but also requires manual disassembly and replacement, which further increases the cost.

[0036] Based on the above defects, the salt absorption component of the present invention improves the structure of the salt valve 2. On the one hand, the lumen 22 of the salt valve 2 extends downward to abut against the inner bottom wall of the salt box 1, and can completely absorb the salt water in the salt box 1 when absorbing saturated salt water, forming a real dry salt box 1, and avoiding the occurrence of salt climbing. On the other hand, since the lumen 22 with a small inner diameter is directly connected to the inner bottom wall of the salt box 1, and its other end is connected to the soft water component through the salt cavity 21 with a large inner diameter via the water pipe 3, when the valve on the water pipe 3 is opened, negative pressure will be formed in the lumen 22 and the salt cavity 21, so that according to the Venturi effect, the small inner diameter structure of the lumen 22 is used to directly automatically absorb the saturated salt water in the salt box 1 into the lumen 22, and then transport it to the soft water component through the salt cavity 21 and the water pipe 3, so as to regenerate the soft water resin in the soft water component, without the need for a power pump or the like to provide power. In this way, the salt absorption component can realize unpowered absorption of saturated brine in the salt box 1, which not only ensures the formation of the dry salt box 1, but also has the characteristics of energy saving and consumption reduction, small limitations, and long service life, which is conducive to greatly reducing costs.

[0037] It should be noted that the valve can be a manual valve or an electric valve, and preferably an electronic stop valve is used, which can be electrically connected to the control device to achieve automatic opening to absorb saturated brine.

[0038] The salt valve 2 includes a valve seat 23, a sleeve 24 and an upper cover 25. One end of the valve seat 23 is connected to the water pipe 3. The sleeve 24 is sleeved on the other end of the valve seat 23 and its upper end is covered with the upper cover 25 to form a salt cavity 21 in the sleeve 24. The tube cavity 22 is arranged on the side of the sleeve 24 and connected to the salt cavity 21 in the sleeve 24.

[0039] The valve seat 23 is arranged at the bottom of the salt valve 2, and one end of the valve seat 23 is a pipe structure for connecting with the water pipe 3. Specifically, one end of the valve seat 23 can be detachably connected with the water pipe 3 through a plug-in structure. One end of the water pipe 3 is placed outside the salt box 1 to connect with the soft water component. The other end of the water pipe 3 extends downward into the salt box 1 and is plugged into one end of the valve seat 23. It is locked by a threaded sleeve structure 7, rivets, screws and other structures to achieve a fixed and sealed connection between the water pipe 3 and the valve seat 23, thereby ensuring stable absorption of saturated salt water and avoiding water leakage.

[0040] It is worth noting that when the plug-in structure of the water pipe 3 and the valve seat 23 is locked by the threaded sleeve structure 7, the locking force needs to be controlled to ensure the sealing to avoid water leakage, and to avoid excessive locking that may cause deformation or damage to the plug-in structure of the water pipe 3 and the valve seat 23, thereby ensuring smooth absorption of saturated salt water.

[0041] The other end of the valve seat 23 is a base structure, which is connected to the pipeline structure. The sleeve 24 is arranged on the base structure. The connection between the two is sealed and docked to form a water channel to ensure stable absorption of saturated salt water and avoid water leakage. The salt chamber 21 and the tube chamber 22 connected in the sleeve 24 are arranged vertically in parallel to form a chamber for absorbing salt. The upper end of the sleeve 24 is an open structure, and the upper cover 25 sealing cover is arranged at the upper end of the sleeve 24, which can cooperate with the inner bottom wall of the salt box 1 to form a sealed chamber in the salt chamber 21 and the tube chamber 22, so that when the valve on the water pipe 3 is opened, the salt chamber 21 and the tube chamber 22 will form a negative pressure chamber, so that according to the Venturi effect, the small inner diameter structure of the tube chamber 22 is used to directly suck the saturated salt water in the salt box 1 into the tube chamber 22 automatically, and then transport it to the soft water component through the salt chamber 21, the valve seat 23 and the water pipe 3 in turn, so that the soft water resin in the soft water component is regenerated, and no power pump or the like is required to provide power.

[0042] It should be noted that the purpose of setting the upper cover 25 is to achieve sealing of the upper end of the sleeve 24. It only needs to be a sealable cover structure, and it can be applied regardless of whether it is a hard cover, a soft cover, or an elastic cover.

[0043] A slot 231 extending vertically through the side of the other end of the valve seat 23 is provided, and a matching insert 241 is provided on the side of the sleeve 24 corresponding to the slot 231. The upper end of the insert 241 is connected to the salt chamber 21, and the lower end of the insert 241 is inserted into the slot 231 and extends to abut against the inner bottom wall of the salt box 1 to form a lumen 22 in the insert 241.

[0044] The slot 231 is arranged on the side of the base structure of the valve seat 23, and the lower end of the valve seat 23 is arranged to abut the inner bottom wall of the salt box 1. The slot 231 is passed through from top to bottom and the lower end abuts the inner bottom wall of the salt box 1. The insert 241 is arranged on the side of the sleeve 24, and its length is sufficient to extend downward to abut the inner bottom wall of the salt box 1. When the insert 241 is inserted into the slot 231, the outer wall of the insert 241 is arranged to fit the inner wall of the slot 231 to form a sealing structure to prevent the saturated salt water from being sucked into the gap between the insert 241 and the slot 231, thereby ensuring that the saturated salt water is sucked into the lumen 22 by the Venturi effect.

[0045] In general, the insert tube 241 can be directly arranged to extend downward and abut against the inner bottom wall of the salt box 1, so as to automatically absorb saturated salt water by utilizing the Venturi effect. The matching arrangement of the insert tube 241 and the slot 231 of the present invention is conducive to improving the stability of the installation of the sleeve 24, thereby ensuring that the lower end of the insert tube 241 can stably abut against the inner bottom wall of the salt box 1, so as to ensure smooth absorption of saturated salt water.

[0046] On the basis of the above structure, a float 26 is provided in the salt chamber 21. The float 26 is provided corresponding to the connection between the sleeve 24 and the other end of the valve seat 23, so that it can fall down to block the connection or float up to open the connection. When the operation of absorbing saturated salt water is not performed, the float 26 falls due to its own weight to block the connection between the sleeve 24 and the valve seat 23. When the valve on the water pipe 3 is opened, negative pressure will be formed in the tube cavity 22 and the salt chamber 21. Therefore, according to the Venturi effect, the small inner diameter structure of the tube cavity 22 is used to directly suck the saturated salt water in the salt box 1 into the tube cavity 22 automatically. The buoyancy of the saturated salt water makes the float 26 float up, thereby opening the connection between the sleeve 24 and the valve seat 23, and then transporting it to the soft water component through the salt chamber 21 and the water pipe 3 in turn, so as to regenerate the soft water resin in the soft water component, without the need for a power pump or the like to provide power. When the saturated brine in the salt box 1 is almost completely absorbed, as the saturated brine in the salt chamber 21 decreases, the buoyancy of the saturated brine on the float 26 gradually decreases. Finally, after the saturated brine in the salt box 1 is completely absorbed, the disappearance of the buoyancy causes the float 26 to fall due to its own weight to seal the connection between the sleeve 24 and the valve seat 23, thereby preventing air from being sucked into the soft water component, thereby ensuring the safety of the valve and the soft water component.

[0047] A support portion 27 is provided at the connection between the sleeve 24 and the other end of the valve seat 23, and the float 26 can fall onto the support portion 27 or float away from the support portion 27. The support portion 27 supports the float 26 to ensure that the float 26 can stably block the connection.

[0048] Furthermore, on the basis of arranging the floating ball 26 in the salt chamber 21, preferably, the upper cover 25 is an elastic structure, and a fixing ring 28 is pressed on the circumferential edge of the top of the upper cover 25, and the fixing ring 28 is fixedly connected to the upper end of the sleeve 24. When the floating ball 26 floats up, there may be a situation where it abuts against the upper cover 25. In order to prevent the upper cover 25 from affecting the floating of the floating ball 26, the upper cover 25 is set to an elastic structure and can protrude upward by a certain height, so as to further increase the size of the salt chamber 21 in the height direction and provide sufficient floating space for the floating ball 26.

[0049] The upper cover 25 and the sleeve 24 are fixed by structures such as clamping, riveting, and screwing. In order to prevent the float 26 from abutting and impacting the upper cover 25 under the action of upward buoyancy, causing loosening or failure of the connection between the upper cover 25 and the sleeve 24, a fixing ring 28 is pressed on the circumferential edge of the top end of the upper cover 25. The fixing ring 28 and the upper end of the sleeve 24 are fixed by structures such as clamping, riveting, and screwing, thereby ensuring a firm connection between the upper cover 25 and the sleeve 24 and ensuring the sealing of the upper end of the sleeve 24.

[0050] Further, see Figure 6-8 The float 26 is positioned by a guide member, which includes an elastic member and / or a float tube 29. The elastic member is fixedly connected to the float 26, and the elastic member is stretched or compressed when the float 26 is floating, and the elastic member is naturally stretched when the float 26 falls to block the connection. The float tube 29 is arranged in the salt chamber 21 and extends to the inner wall of the sealed connection. The float 26 is arranged in the float tube 29 and can fall to block the lower end of the float tube 29 or float to open the lower end of the float tube 29. The lower end of the float tube 29 is provided with a water hole 291 to connect with the valve seat 23, and the upper end of the float tube 29 is provided with a through hole 292 to connect with the salt chamber 21.

[0051] When the brine is absorbed, the float 26 floats up due to the buoyancy of the saturated brine. Due to the fluidity of the saturated brine, the position of the float 26 is easily offset. After the saturated brine in the salt box 1 is absorbed, the disappearance of the buoyancy makes the position of the float 26 easily offset due to its own weight, and it is impossible to seal the connection between the sleeve 24 and the valve seat 23, so there is a possibility of air absorption. The purpose of setting the guide is to guide and locate the position of the float 26, so as to ensure that after the saturated brine in the salt box 1 is absorbed, the disappearance of the buoyancy makes the float 26 fall due to its own weight to accurately seal the connection between the sleeve 24 and the valve seat 23, thereby avoiding air absorption.

[0052] The guide member can be an elastic member such as a spring, wherein the axis thereof is in a straight line with the center axis of the support portion. One end of the spring is fixedly connected to the float 26, and the other end thereof can be fixedly connected to the inner bottom wall of the valve seat 23. When the float 26 falls due to its own weight to block the connection between the sleeve 24 and the valve seat 23, the spring is in a naturally extended state. When the valve on the water pipe 3 is opened, negative pressure is formed in the lumen 22 and the salt chamber 21, and thus, according to the Venturi effect, the saturated salt water in the salt box 1 is automatically sucked into the lumen 22 by utilizing the small inner diameter structure of the lumen 22. The buoyancy of the saturated salt water causes the float 26 to float, thereby opening the connection between the sleeve 24 and the valve seat 23, and the spring is stretched. When the saturated brine in the salt box 1 is almost completely absorbed, as the saturated brine in the salt chamber 21 decreases, the buoyancy of the saturated brine on the float 26 gradually decreases. Finally, after the saturated brine in the salt box 1 is completely absorbed, the disappearance of the buoyancy causes the float 26 to fall due to its own weight and cooperate with the elastic force of the spring to allow the float 26 to fall on the support portion 27 to seal the connection between the sleeve 24 and the valve seat 23.

[0053] Alternatively, one end of the spring is fixedly connected to the float 26, and the other end thereof can be fixedly connected to the inner top wall of the upper cover 25. When the float 26 falls due to its own weight to block the connection between the sleeve 24 and the valve seat 23, the spring is in a naturally extended state. When the valve on the water pipe 3 is opened, negative pressure will be formed in the lumen 22 and the salt chamber 21, so that according to the Venturi effect, the saturated salt water in the salt box 1 is automatically sucked into the lumen 22 by utilizing the small inner diameter structure of the lumen 22. The buoyancy of the saturated salt water makes the float 26 float up, so that when the connection between the sleeve 24 and the valve seat 23 is opened, the spring is compressed. When the saturated salt water in the salt box 1 is almost completely absorbed, as the saturated salt water in the salt chamber 21 decreases, the buoyancy of the saturated salt water on the float 26 gradually decreases. Finally, after the saturated salt water in the salt box 1 is completely absorbed, the disappearance of the buoyancy makes the float 26 fall due to its own weight and cooperates with the elastic force of the spring to make the float 26 fall on the support part 27 to block the connection between the sleeve 24 and the valve seat 23.

[0054] The guide member can also be a float cylinder 29, the upper part of which is a cylindrical structure to accommodate the float 26, and the float 26 can move up and down in the cylindrical structure, and a through hole 292 is provided on the upper side of the cylindrical structure to connect the salt cavity 21. The lower part of the float cylinder 29 is an inverted cone structure, the lower part of the inverted cone structure is inserted into the support part 27, and the outer wall of the inverted cone structure is sealed and connected with the inner wall of the top end of the support part 27, and the part where the inverted cone structure is inserted into the support part 27 is provided with a water hole 291 to connect the inverted cone structure with the valve seat 23. The upper part of the inverted cone structure is inserted into the lower part of the float cylinder 29 and the two are fixed by clamping, and the upper outer wall of the inverted cone structure is sealed and connected with the lower inner wall of the float cylinder 29, and the two are connected, and the float 26 blocks the top of the inverted cone structure in the falling state.

[0055] In this way, when the float 26 is in a floating state, the salt chamber 21 is connected to the valve seat 23 through the through hole 292 and the water hole 291. When the saturated salt water is not absorbed, the float 26 falls due to its own weight to block the top opening of the inverted cone structure. When the valve on the water pipe 3 is opened, a negative pressure will be formed in the lumen 22 and the salt chamber 21. According to the Venturi effect, the saturated salt water in the salt box 1 is automatically sucked into the lumen 22 by utilizing the small inner diameter structure of the lumen 22, and enters the salt chamber 21 and the float tube 29 through the through hole 292. The buoyancy of the saturated salt water makes the float 26 float, thereby opening the top opening of the inverted cone structure, so that the saturated salt water is sequentially delivered to the soft water component through the valve seat 23 and the water pipe 3, so as to regenerate the soft water resin in the soft water component, without the need for a power pump or the like to provide power. When the saturated salt water in the salt box 1 is almost completely absorbed, as the saturated salt water in the salt chamber 21 and the float tube 29 decreases, the buoyancy of the saturated salt water on the float 26 gradually decreases. Finally, after the saturated salt water in the salt box 1 is completely absorbed, the disappearance of the buoyancy causes the float 26 to fall due to its own weight and block the top opening of the inverted cone structure, thereby avoiding the absorption of air. The setting of the float tube 29 guides and limits the up and down movement of the float 26, thereby ensuring that the float 26 can accurately block the top opening of the inverted cone structure after falling.

[0056] The water holes 291 can be provided on the tip of the inverted cone structure or on the side wall of the inverted cone structure. The number of the water holes 291 is not limited, as long as it can ensure that the saturated salt water only enters the valve seat 23 through the float tube 29 .

[0057] In addition, a circle of grooves may be provided at the top of the inverted cone structure, and the grooves surround the circumference of the float 26 in the falling state. When absorbing saturated salt water, after the saturated salt water enters the cylindrical structure of the float tube 29 from the through hole 292, the saturated salt water flows downward to the grooves to form a vortex, which drives the float 26 to float up with a greater impact force, which is conducive to the rapid buoyancy of the float 26, so as to ensure the rapid absorption of saturated salt water into the soft water component.

[0058] The float tube 29 is fixedly connected with a fixing rod 4, which passes through the salt valve 2 in a sealed manner and is fixed by a fixing frame 5. The impact force of the saturated salt water and the buoyancy of the float 29 may impact the float tube 29, thereby affecting the stability of the float tube 29, thereby affecting the stability of the connection between the float tube 29 and the support part 27, and it is impossible to ensure that air is not sucked away. The setting of the fixing rod 4 can fix the float tube 29 to achieve a stable and sealed connection between the float tube 29 and the support part.

[0059] One end of the fixing rod 4 is fixedly connected to the float tube 29, and the other end of the fixing rod 4 is sealed and passes through the salt valve 2 and is fixed by the fixing frame 5. The fixing frame 5 can be fixed on the water pipe 3, so that the water pipe 3 is used as a basic support, and the float tube 29 is stably installed by the fixing frame 5 and the fixing rod 4. The fixing frame 5 and the fixing rod 4 can be connected by welding, clamping, screwing, etc.

[0060] The fixing bracket 5 can be threadedly locked on the water pipe 3 by the locking member 8. It is worth noting that the locking force of the locking member 8 needs to be moderate, which can not only ensure that the fixing bracket 5 can be firmly locked on the water pipe 3, but also avoid excessive locking that may cause deformation or damage to the water pipe 3, thereby avoiding affecting the smooth absorption of saturated salt water.

[0061] In addition to the above structures, see Figure 2 The salt box 1 is provided with a salt valve chamber 11 and at least one salt box chamber 12. A salt box 13 is detachably provided in the salt box chamber 12. The salt valve 2 is provided in the salt valve chamber 11 and communicates with the salt box 13 in the salt box chamber 12 through a pipeline. The salt valve chamber 11 is used to accommodate the salt valve 2. One end of the water pipe 3 is placed outside the salt box 1 to connect to the soft water component. The other end of the water pipe 3 extends downward into the salt box 1 to be plugged into one end of the valve seat 23 of the salt valve 2. The salt box chamber 12 is used to accommodate the salt box 13. The salt valve chamber 11 is connected to the salt box 13 in the salt box chamber 12 through a pipeline, so that the water levels of the saturated salt water in the salt valve chamber 11 and the salt box 13 are kept level. When saturated salt water is absorbed, the saturated salt water in the salt valve chamber 11 is first sucked into the lumen 22 due to the Venturi effect. As the water level in the salt valve chamber 11 decreases, the saturated salt water in the salt box 13 is continuously replenished into the salt valve chamber 11 through the pipeline to ensure that the water levels in the salt valve chamber 11 and the salt box 13 are kept level until the saturated salt water in the salt box 1 is completely absorbed.

[0062] The salt box 13 is detachably mounted in the salt box chamber 12, so that when the soft water salt in the salt box 13 is insufficient, the soft water salt can be replenished by removing the salt box 13. The salt box chamber 12 can be provided with one, or two or more, and can be provided according to the requirements of weight, soft water salt usage, etc.

[0063] In addition to the above-mentioned salt absorption component, the present invention also provides a water heater, including: a water heater body 6 and the above-mentioned salt absorption component, the salt absorption component is detachably arranged at the bottom of the water heater body 6, the water heater body 6 includes a hot water component and a soft water component, the salt valve 2 is connected to the soft water component through a water pipe 3, and the salt box 1 is connected to external water through a pipeline to replenish water into the salt box 1, and the pipeline and the water pipe 3 can be the same pipe or two pipes respectively.

[0064] One end of the water pipe 3 is placed in the water heater body 6 to connect the water softening component, and the other end of the water pipe 3 extends into the salt valve chamber 11 to connect the salt valve 2. The valve can be an electronic stop valve arranged at one end of the water pipe 3, which is electrically connected to the control device of the water heater body 6, and can realize automatic absorption of saturated salt water. In this way, when it is necessary to absorb saturated salt water to regenerate the water softening resin in the water softening component, the passage of the electronic stop valve is controlled by the control device to open, and negative pressure is formed in the tube cavity 22 and the salt cavity 21. Therefore, according to the Venturi effect, the small inner diameter structure of the tube cavity 22 is used to directly automatically absorb the saturated salt water in the salt box 1 into the tube cavity 22, and enter the salt cavity 21 and enter the float cylinder 29 through the through hole 292. The buoyancy of the saturated salt water causes the float 26 to float, thereby opening the top opening of the inverted cone structure, so that the saturated salt water is sequentially transported to the water softening component through the valve seat 23 and the water pipe 3, so as to regenerate the water softening resin in the water softening component, without the need for a power pump or the like to provide power. A brine concentration detector may be provided in the brine box 1 to detect the amount of saturated brine in the brine box 1. After the saturated brine is absorbed, the brine concentration detector may feedback the structure to the control device, so that the electronic stop valve can be closed through the control device to complete the absorption of saturated brine.

[0065] Since the salt absorption subassembly can realize unpowered absorption of saturated salt water in the salt box 1, it not only ensures the formation of the dry salt box 1, but also has the characteristics of energy saving, small limitations and long service life, which is conducive to greatly reducing the cost of the water heater.

[0066] Since one end of the water pipe 3 is arranged in the water heater body 6, a protective cover 9 is provided at one end of the water pipe 3, and the end of the water pipe 3 passes through the protective cover 9 to connect the soft water component to avoid damage during installation.

[0067] The formation of saturated salt water in the salt box 1 is achieved by replenishing water into the salt box 1 to dissolve the soft water salt. The salt box 1 is connected to external water through a pipeline to replenish water into the salt box 1. The pipeline and the water pipe 3 can be two different pipes respectively, and the two are not connected. Or the pipeline and the water pipe 3 are the same pipe, and one end of the water pipe 3 can also be connected to external water. One end of the water pipe 3 can be provided with a double-channel electronic stop valve to open different channels of the electronic stop valve during water injection and absorbing saturated salt water. When injecting water, the external water is introduced into the salt valve 2, passes through the valve seat 23, the float cylinder 29 and the salt cavity 21 in sequence, enters the tube cavity 22, and then flows into the salt valve cavity 11 and the salt box 13 to dissolve the soft water salt to form saturated salt water.

[0068] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
