Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, in particular to a water treatment device and a household water appliance using water. Background Art

[0002] With the improvement of living standards, the hygienic safety of household water use has been paid more and more attention. In the prior art, in order to play an active pre-protection role in concealed pipelines, faucets, plumbing, water heaters, boilers, washing machines, toilets, dishwashers, coffee machines and other household water appliances (water purifiers, pure water machines, water softeners), etc., a water treatment device is usually provided at the front end of the household water appliance. The water treatment device can filter out visible impurities in the water such as sediment, rust, floating objects, etc., and can further perform water treatment such as scale inhibition, scale removal, bacteriostasis, sterilization, mineralization and disinfection on the water used, which can significantly improve the water quality and greatly extend the service life of subsequent equipment.

[0003] Generally, the water used is treated by filling water treatment material particles in the water treatment device. The water treatment material particles are in a non-fixed state. After being used for a period of time, the volume of the water treatment material particles will shrink, the gap between them will increase, and the water treatment material particles will move randomly with the water flow, resulting in collisions between the water treatment material particles, and it is easy to occur the situations of breakage and pulverization, thus causing the water treatment material particles to fail and the service life to be greatly reduced, increasing the use cost. Summary of the Invention

[0004] One of the purposes to be achieved by the present invention is to provide a water treatment device, which solves the problem that the water treatment material particles are easily damaged in the prior art, effectively protects the water treatment material particles, improves the service life of the water treatment material particles, and reduces the use cost of users.

[0005] To achieve the above purpose, the present invention adopts the following technical solution: A water treatment device includes a container, the container has a filling cavity for filling water treatment material particles, a water inlet and a water outlet communicated with the filling cavity. A flexible material body is provided in the filling cavity, and the flexible material body provides a pre-tightening force to extrude the water treatment material particles, so that the gap between the water treatment material particles becomes smaller and relatively fixed.

[0006] After adopting the above technical solution, the present invention has the following advantages: The flexible material body provides a pre-tightening force to squeeze the water treatment material particles, reducing the gap between the water treatment material particles, ensuring that the water treatment material particles are in a mutually fixed state. When water flows, it is not easy to drive the relative movement of the water treatment material particles, effectively reducing the friction between the water treatment material particles. The water treatment material particles will not collide due to random movement with the water flow, greatly reducing the risk of fragmentation and pulverization, ensuring that the water treatment material particles can still basically maintain their initial particle size after long-term use. Even if the volume of the water treatment material particles shrinks due to use after a long time, or even some water treatment material particles are damaged, as long as the flexible material body can continue to release the pre-tightening force to maintain the mutually fixed state between the water treatment material particles before restoring its deformation, and the flexible material body can provide flexible contact points for the movement and collision of the water treatment material particles, realizing the flexible restraint of the water treatment material particles, effectively reducing the risk of collision and damage of the water treatment material particles after movement, greatly increasing the service life of the water treatment material particles, reducing the frequency of replacing the water treatment material particles, and reducing the user's usage cost. In addition, the flexible material body has a certain elasticity and can also buffer the impact of high-pressure and high-speed water flow on the water treatment material particles, reducing the vibration of the water treatment material particles, and further preventing the water treatment material particles from being damaged. Moreover, the gap between the water treatment material particles becomes smaller, effectively reducing the impurities filled and attached to the gap between the water treatment material particles, weakening the frictional effect of the impurities on the water treatment material particles, reducing the influence of the impurities on the water treatment material particles, and further effectively reducing the risks such as damage and pulverization of the water treatment material particles; the smaller gap between the water treatment material particles can make the water flow through the filling cavity more evenly, which is beneficial for all water treatment material particles to effectively exert their water treatment efficiency, improving the efficiency and effect of water treatment, and enhancing the stability of the treated water quality.

[0007] Furthermore, the flexible material body is granular, and the flexible material body and the water treatment material particles are mixed and filled into the filling cavity. By adopting the foregoing technical solution, the granular flexible material body can be better mixed with the water treatment material particles, ensuring a more uniform distribution of the flexible material body and the water treatment material particles in the filling cavity, a larger contact area between the flexible material body and the water treatment material particles, the flexible material body can provide a more uniform and stable pre-tightening force to squeeze the water treatment material particles, reducing the number of direct contacts between the water treatment material particles, further reducing the wear of the water treatment material particles, and at the same time improving the uniformity of the water flow, and further optimizing the water treatment effect.

[0008] Furthermore, both the flexible material body and the water treatment material particles are round granular and have the same diameter size range. With the aforementioned technical solution, the round granular flexible material body and the water treatment material particles have similar shapes and sizes, which can be better compatible and extruded with each other, facilitating the reduction of the gap between the water treatment material particles, enabling more uniform distribution during filling, ensuring the uniformity of water flow, improving the stability of the materials in the filling cavity, optimizing the water treatment effect, and making it easier to control the filling amount in the filling cavity.

[0009] Furthermore, the flexible material body is in the shape of a plug at the end of the filling cavity away from the water outlet. With the aforementioned technical solution, the plug-shaped flexible material body can provide a greater amount of deformation, enabling the water treatment material particles to obtain a long-term pre-tightening force, thereby better supporting the water treatment material particles in the long term, providing a stable long-term supporting effect for the water treatment material particles, ensuring that the water treatment material particles will not be washed away due to excessive water pressure during the water treatment process, and can also reduce the actual use volume of the filling cavity, making the gap between the water treatment material particles in the filling cavity smaller, ensuring the mutual fixation state between the water treatment material particles, further reducing the wear of the water treatment material particles, and effectively reducing the risks of breakage and pulverization of the water treatment material particles.

[0010] Furthermore, the volume ratio of the flexible material body to the water treatment material particles is 1 before filling into the filling cavity and 0.64 - 0.8 after filling into the filling cavity. With the aforementioned technical solution, the flexible material body and the water treatment material particles are filled into the filling cavity at a volume ratio of 1:1, facilitating the calculation of the usage amounts of the flexible material body and the water treatment material particles. During the water treatment process, the volume of the water treatment material particles soaked in water will increase, and the flexible material body will be continuously compressed. The flexible material body provides a greater pre-tightening force to extrude the water treatment material particles, ensuring that the water treatment material particles remain mutually fixed. If the volume ratio of the flexible material body to the water treatment material particles after filling into the filling cavity is less than 0.64, it will cause the flexible material body to be over-compressed, and the flexible material body will exert too large a pre-tightening force on the water treatment material particles, easily causing the water treatment material particles to be crushed; if the volume ratio of the flexible material body to the water treatment material particles after filling into the filling cavity is greater than 0.8, it is easy to cause the pre-tightening force exerted by the flexible material body on the water treatment material particles to be too small, unable to effectively compress the water treatment material particles, and easily causing wear of the water treatment material particles.

[0011] Furthermore, the Shore hardness of the flexible material body is 20° to 70°. With the foregoing technical solution, the flexible material body has good elasticity and resilience. After the volume of the water treatment material particles increases, a pressure is applied to the flexible material body. The flexible material body has a tendency to quickly return to its original shape and provides a pre-tightening force to the water treatment material particles, prompting the gaps between the water treatment material particles to become smaller and fixing them to each other. Moreover, it can provide an appropriate pre-tightening force. The flexible material body will neither be too soft to effectively squeeze the water treatment material particles nor be too hard to cause damage to the water treatment material particles, achieving flexible restraint of the water treatment material particles, improving the efficiency of water treatment, and achieving good water treatment effects. The Shore hardness range of 20° to 70° is relatively wide and can adapt to different water treatment requirements. If the Shore hardness of the flexible material body is less than 20°, the flexible material body cannot provide sufficient elasticity and resilience, making it difficult to effectively squeeze the water treatment material particles, resulting in the inability to effectively reduce the gaps between the water treatment material particles. The water treatment material particles are prone to collide and break due to the movement of the water flow. The softer flexible material body cannot provide sufficient support force, causing the water treatment material particles to be washed away and broken during the water treatment process. If the Shore hardness of the flexible material body is greater than 70°, the flexible material body is too hard and not prone to deformation, unable to provide sufficient pre-tightening force to compress the water treatment material particles, resulting in relatively large gaps between the water treatment material particles. The water treatment material particles are prone to friction with each other and will move randomly with the water flow, easily leading to wear of the water treatment material particles.

[0012] Furthermore, the container further has a water flow stabilizing chamber, which is located downstream of the water inlet and upstream of the filling chamber, and a buffer material is provided in the water flow stabilizing chamber. With the foregoing technical solution, the buffer material can absorb part of the impact force of the water flow, reduce the impact and direct wear on the water treatment material particles, and press the water flow into the filling chamber stably and evenly, which is beneficial to extending the service life of the water treatment material particles.

[0013] Furthermore, the container further has a water flow stabilizing chamber, which is located downstream of the water inlet and upstream of the filling chamber, and the cross-sectional area of the water flow stabilizing chamber is larger than that of the water inlet. With the foregoing technical solution, the water flow velocity in the water flow stabilizing chamber is less than that in the water inlet, reducing the impact of the water flow on the filling chamber, reducing the breakage and friction of the water treatment material particles, and ensuring the stability and integrity of the water treatment material particles in the filling chamber.

[0014] Furthermore, the filling chamber has a water outlet hole communicating with the water outlet, and a one-way water outlet valve is provided at the water outlet hole. With the foregoing technical solution, the water flowing out of the filling chamber cannot flow back into the filling chamber, ensuring the stability and reliability of the treated water quality.

[0015] Further, the filling cavity has a water inlet hole communicating with the water inlet, and a first filter layer is provided at the water inlet hole. With the foregoing technical solution, the first filter layer can block impurities in the water from entering the filling cavity, avoid the increase of wear on the water treatment material particles caused by impurities, and further protect the water treatment material particles.

[0016] The present invention also provides a water-using household appliance, including a water inlet pipe, and the water inlet pipe is connected with the water treatment device described in any one of the foregoing technical solutions. With the foregoing technical solution, the service life of the water treatment material particles is greatly improved, the frequency of replacing the water treatment material particles is reduced, thereby prolonging the service life of the components associated with the water treatment device in the water-using household appliance, greatly reducing the user's usage cost, protecting the water-using household appliance, and prolonging the service life of the water-using household appliance.

[0028] Embodiment 1:

[0029] As Figure 1 shown, the present invention provides a water treatment device, which includes a container 1. The container 1 has a filling cavity 10 filled with water treatment material particles 21, a water inlet 3 and a water outlet 4 communicating with the filling cavity 10. A flexible material body 22 is provided in the filling cavity 10. The flexible material body 22 provides a pre-tightening force to squeeze the water treatment material particles 21, so that the gaps between the water treatment material particles 21 become smaller and relatively fixed.

[0030] In this embodiment, the flexible material body 22 provides a pre-tightening force to squeeze the water treatment material particles 21, so that the gaps between the water treatment material particles 21 become smaller, which can ensure that the water treatment material particles 21 are in a fixed state with each other. When the water flows, it is not easy to drive the water treatment material particles 21 to move relative to each other, effectively reducing the friction between the water treatment material particles 21. The water treatment material particles 21 will not collide with the random movement of the water flow, greatly reducing the risk of fragmentation and pulverization, and ensuring that the water treatment material particles 21 can still basically maintain the initial particle size after long-term use. Even after long-term use, the water treatment material particles 21 1, resulting in reduced usability, and even worse, some water treatment material particles 21 are damaged. As long as the flexible material body 22 can continue to release the preload before recovering its deformation to maintain the mutual fixation between the water treatment material particles 21, and the flexible material body 22 can provide a flexible contact point for the water treatment material particles 21 to move and collide, it can achieve flexible restraint of the water treatment material particles 21, effectively reducing the risk of collision and damage of the water treatment material particles 21 after movement, greatly improving the service life of the water treatment material particles 21, reducing the frequency of replacement of the water treatment material particles 21, and reducing the user's cost of use. In addition, the flexible material body 22 has a certain degree of elasticity and can also alleviate the impact of high-pressure and high-speed water flow on the water treatment material particles 21, reduce the vibration of the water treatment material particles 21, and further prevent the water treatment material particles 21 from being damaged. Moreover, the gaps between the water treatment material particles 21 become smaller, effectively reducing the impurities filling and adhering to the gaps between the water treatment material particles 21, weakening the friction of the impurities on the water treatment material particles 21, and weakening the impact of the impurities on the water treatment material particles 21, further effectively reducing the risks of breakage and pulverization of the water treatment material particles 21; the gaps between the water treatment material particles 21 become smaller, which can make the water flow more evenly through the filling cavity, which is beneficial for all water treatment material particles 21 to effectively exert their water treatment efficiency, improve the efficiency and effect of water treatment, and improve the stability of the treated water quality.

[0031] Among them, the flexible material body 22 refers to a material that has a reduced volume under pressure and can restore its original shape after continuous pressure is applied. It has good elasticity and recovery. Rubber and silicone materials can be used, but are not limited to these. The selection of the flexible material body 22 can be determined based on specific water treatment requirements and water quality conditions to ensure its effectiveness in the water treatment process.

[0032] Preferably, the volume compression ratio of the flexible material body 22 after filling is Q, 0<Q≤25%, for example, Q is 5%, 10%, 12.5%, 15%, 20% or 25%, etc., to ensure that the water treatment material particles 21 are squeezed and compacted by the elastic material, which can better ensure the stability of the water treatment material particles 21, reduce the damage of the water treatment material particles 21, and extend the service life of the flexible material body 22; if Q>25%, the volume compression ratio of the flexible material body 22 after filling is too large, resulting in excessive pressure on the flexible material body 22, which will cause the water treatment material particles 21 to be subjected to excessive pressure, resulting in an increased possibility of damage to the water treatment material particles 21, affecting the efficiency and effect of water treatment. Moreover, if the flexible material body 22 is deformed too much, it will cover the surface of the water treatment material particles 21, resulting in a reduction in the surface area of the water treatment material particles 21 in contact with water, which is not conducive to the efficiency and effect of water treatment.

[0033] like Figure 1 As shown, in order to ensure that the flexible material body 22 can provide a more uniform and stable pre-tightening force to squeeze the water treatment material particles 21, in one embodiment, the flexible material body 22 can be set to a granular shape, and the flexible material body 22 and the water treatment material particles 21 are mixed and filled into the filling cavity 10. The granular flexible material body 22 can better mix with the water treatment material particles 21, ensuring that the flexible material body 22 and the water treatment material particles 21 in the filling cavity 10 are more evenly distributed, and the contact area between the flexible material body 22 and the water treatment material particles 21 is larger. The flexible material body 22 can provide a more uniform and stable pre-tightening force to squeeze the water treatment material particles 21, reduce the number of direct contacts between the water treatment material particles 21, further reduce the wear of the water treatment material particles 21, and at the same time improve the uniformity of the water flow, further optimizing the water treatment effect.

[0034] Preferably, the flexible material body 22 and the water treatment material particles 21 are mixed evenly and then filled into the filling cavity 10, ensuring a more even distribution of the flexible material body 22 and the water treatment material particles 21, and a more uniform preload force provided by the flexible material body 22. Alternatively, the flexible material body 22 and the water treatment material particles 21 can be separately filled into the filling cavity 10, and the order of filling is not limited.

[0035] To ensure that the flexible material body 22 does not easily crush the water treatment material particles 21 when squeezing them, in one embodiment, the flexible material body 22 and the water treatment material particles 21 are both spherical and have the same diameter range. The spherical flexible material body 22 and the water treatment material particles 21 have similar shapes and sizes, which allows for better compatibility and mutual squeezing, thereby reducing gaps between the water treatment material particles 21 and allowing for more uniform distribution during filling. This ensures uniform water flow, improves the stability of the material within the filling cavity 10, optimizes the water treatment effect, and makes it easier to control the filling amount in the filling cavity 10.

[0036] In order to ensure that after the flexible material body 22 extrudes the water treatment material particles 21, the gap between the water treatment material particles 21 becomes smaller and relatively fixed. In one embodiment, the volume ratio of the flexible material body 22 to the water treatment material particles 21 is 1 before being filled into the filling cavity 10, and is 0.64 - 0.8 after being filled into the filling cavity 10. For example, after being filled into the filling cavity 10, the volume ratio of the flexible material body 22 to the water treatment material particles 21 can be set to 0.64, 0.7, 0.72, 0.75 or 0.8. Filling the flexible material body 22 and the water treatment material particles 21 into the filling cavity 10 at a volume ratio of 1:1 facilitates calculating the usage amounts of the flexible material body 22 and the water treatment material particles 21. During the water treatment process, the volume of the water treatment material particles 21 soaked in water will increase, and the flexible material body 22 is continuously compressed. The flexible material body 22 provides a greater pre-tightening force to extrude the water treatment material particles 21, ensuring that the water treatment material particles 21 remain fixed to each other. If the volume ratio of the flexible material body 22 to the water treatment material particles 21 after being filled into the filling cavity 10 is less than 0.64, it will cause the flexible material body 22 to be over-compressed, and the flexible material body 22 will apply too large a pre-tightening force to the water treatment material particles 21, easily causing the water treatment material particles 21 to be crushed. If the volume ratio of the flexible material body 22 to the water treatment material particles 21 after being filled into the filling cavity 10 is greater than 0.8, it is easy to cause the pre-tightening force applied by the flexible material body 22 to the water treatment material particles 21 to be too small, unable to effectively compress the water treatment material particles 21, and easily causing wear of the water treatment material particles 21.

[0037] In another embodiment, the volume ratio V of the flexible material body 22 in the filling cavity 10 is ≥ 20%. The flexible material body 22 can provide sufficient extrusion effect to ensure that the water treatment material particles 21 are fully extruded, and to ensure that the gap between the water treatment material particles 21 becomes smaller and they are fixed to each other. If the volume ratio V of the flexible material body 22 in the filling cavity 10 is < 20%, there is too little flexible material body 22 in the filling cavity 10, and the water treatment material particles 21 cannot be fully extruded, resulting in insufficient extrusion effect provided by the flexible material body 22, larger gaps between the water treatment material particles 21, easy breakage of the water treatment material particles 21, and poor water treatment effect.

[0038] In order to ensure the stability of squeezing the water treatment material particles 21 by the flexible material body 22, in one embodiment, the Shore hardness of the flexible material body 22 is 20° to 70°. For example, the Shore hardness of the flexible material body 22 is 20°, 30°, 40°, 45°, 50°, 60° or 70°, etc. The flexible material body 22 has good elasticity and recoverability. After the volume of the water treatment material particles 21 increases, a pressure is exerted on the flexible material body 22. The flexible material body 22 has a tendency to quickly return to its original state and provides a pre-tightening force to the water treatment material particles 21, prompting the gaps between the water treatment material particles 21 to become smaller and relatively fixed, and can provide an appropriate pre-tightening force. The flexible material body 22 will neither be too soft to effectively squeeze the water treatment material particles 21 nor be too hard to cause the water treatment material particles 21 to break, realizing the flexible restraint of the water treatment material particles 21, improving the efficiency of water treatment, and achieving a good water treatment effect. The Shore hardness range of 20° to 70° is relatively wide and can adapt to different water treatment requirements.

[0039] If the Shore hardness of the flexible material body 22 is less than 20°, it will cause the flexible material body 22 to be unable to provide sufficient elasticity and recoverability, making it difficult to effectively squeeze the water treatment material particles 21, resulting in the gaps between the water treatment material particles 21 not being effectively reduced. The water treatment material particles 21 are likely to move and collide with each other under the water flow and break, affecting the efficiency of water treatment. The softer flexible material body 22 cannot provide enough support force, resulting in the water treatment material particles 21 being washed away and broken during the water treatment process. If the Shore hardness of the flexible material body 22 is greater than 70°, it will cause the flexible material body 22 to be too hard, and the flexible material body 22 is not easily deformed, unable to provide enough pre-tightening force to compress the water treatment material particles 21, resulting in relatively large gaps between the water treatment material particles 21. The water treatment material particles 21 are prone to friction with each other, will move randomly with the water flow, and are likely to cause wear of the water treatment material particles 21.

[0040] Such as Figure 2As shown, to reduce the impact of water flow on the water treatment material particles 21, in one embodiment, the container 1 further comprises a water flow stabilizing chamber 5, located downstream of the water inlet 3 and upstream of the filling chamber 10. A buffer material 51 is disposed within the water flow stabilizing chamber 5. The buffer material 51 has a concave cavity 511 opening toward the water inlet 3. A support member 52 is disposed between the buffer material 51 and the bottom wall of the water flow stabilizing chamber 5. The support member 52 has a connecting hole connecting the concave cavity 511 with the water flow stabilizing chamber 5. Water enters the concave cavity 511 from the water inlet 3, collides with the buffer material 51, and then flows through the connecting hole of the support member 52 into the water flow stabilizing chamber 5 and then into the filling chamber 10. The buffer material 51 can absorb some of the impact of the water flow, reducing the impact and direct wear on the water treatment material particles 21. It can also ensure that the water flow is stably and evenly pressed into the filling chamber 10, thereby extending the service life of the water treatment material particles 21. The buffer material 51 is made of a flexible material such as rubber or silicone.

[0041] In another embodiment, the container 1 further has a water flow stabilizing chamber 5, which is located downstream of the water inlet 3 and upstream of the filling chamber 10. The cross-sectional area of the water flow stabilizing chamber 5 is larger than the cross-sectional area of the water inlet 3, resulting in the water flow velocity in the water flow stabilizing chamber 5 being smaller than the water flow velocity in the water inlet 3, thereby reducing the impact of the water flow on the filling chamber 10, reducing the damage and friction of the water treatment material particles 21, and ensuring the stability and integrity of the water treatment material particles 21 in the filling chamber 10.

[0042] To prevent impurities in the water from entering the filling chamber 10, in one embodiment, the filling chamber 10 has a water inlet hole connected to the water inlet 3. A first filter layer is provided at the water inlet hole. The first filter layer can prevent impurities in the water from entering the filling chamber 10, prevent impurities from increasing the wear of the water treatment material particles 21, and further protect the water treatment material particles 21. The first filter layer can be made of nylon mesh, PP cotton, ultrafiltration membrane, nanofiltration membrane, etc., and one or more of these can be used. The filtration accuracy is generally less than 200 microns, ensuring that impurities do not enter the filling chamber 10.

[0043] like Figure 2 As shown, to ensure that water flows from the water flow stabilization chamber 5 into the filling chamber 10, in one embodiment, an upper cover 11 and a lower cover 12 are provided at each end of the filling chamber 10. A water inlet hole is provided on the lower cover 12, and multiple water inlet holes may be provided. Water flows into the filling chamber 10 through the water inlet holes. A sealing ring 111 is provided on the side of the upper cover 11, which presses against the inner wall of the container 1 to prevent water from overflowing from the edge of the upper cover 11. An angle valve 31 can be installed on the water inlet 3 to control the on and off of the water inlet.

[0044] In one embodiment, to prevent the backflow of the treated water, the filling cavity 10 is provided with a water outlet hole 6 communicating with the water outlet 4, and a one-way water outlet valve is provided at the water outlet hole 6, so that the water flowing out of the filling cavity 10 cannot flow back into the filling cavity 10, ensuring the stability and reliability of the treated water quality.

[0045] As Figure 3 shown, in one embodiment, to further filter the water for use, the filling cavity 10 is provided in the core body 9. The core body 9 is detachably installed in the container 1. The core body 9 can be set as a hollow cylindrical structure, and the hollow part forms the filling cavity 10. A flexible material body 22 and water treatment material particles 21 are filled in the hollow part. An inlet gap 91 communicating with the water inlet 3 is formed between the outer wall of the core body 9 and the inner wall of the container 1. A plurality of water inlet holes are provided on the outer periphery of the core body 9. The water in the inlet gap 91 flows into the filling cavity 10 through the water inlet holes. A second filter layer covering the water inlet holes is provided on the outer periphery of the core body 9. A water outlet hole 6 is provided at the end of the core body 9 facing the water outlet 4, and a one-way water outlet valve is provided at the water outlet hole 6. The upper cover 11 and the lower cover 12 are located at both ends of the core body 9. The upper cover 11 is hermetically connected to the inner wall of the container 1 through a sealing ring 111. The inlet gap 91 is located between the lower cover 12 and the inner wall of the container 1. The water for use flows to the inlet gap 91 and flows into the filling cavity 10 through the water inlet holes.

[0046] By providing a plurality of water inlet holes on the core body 9, the water flow rate and velocity can be better controlled, ensuring that the water flows evenly through the filling cavity 10, protecting the water treatment material particles 21 from being impacted and broken, and achieving a better water treatment effect. The second filter layer can further filter the water for use entering the filling cavity 10, ensuring that the impurities entering the filling cavity 10 are reduced, reducing the risk of the impurities rubbing against the water treatment material particles 21 and causing their damage, reducing the water treatment burden of the water treatment material particles 21, and prolonging the service life of the water treatment material particles 21. The one-way water outlet valve prevents the treated water from flowing back into the filling cavity 10, ensuring the stability of the water quality. With the above structure, the structure of the water treatment device can be made more compact. It can be understood that in order to achieve the filtering function, the filter can also be provided upstream of the filling cavity 10. For example, the outlet of the filter is connected and communicated with the water inlet 3 of the filling cavity 10, so that the filter and the water treatment material particles 21 can be replaced separately without affecting each other.

[0047] As Figures 4 to 6As shown in the figure, the one-way water outlet valve includes an elastic member 71, a valve core 72, and a fixing column 73. One end of the valve core 72 is closed, and the other end is provided with a support groove 75 for the elastic member 71 and the fixing column 73 to extend into. The elastic member 71 is sleeved on the fixing column 73, and one end of the elastic member 71 abuts against the valve core 72. The valve core 72 and the water outlet hole 6 are in a normally closed state. When the treated water flows out to fill the cavity 10, the water pressure increases to push the closed valve core 72, so that the valve core 72 is kept in communication with the water outlet hole 6, and the elastic member 71 is squeezed and contracted. The treated water flows out from the water outlet hole 6. When the treated water flows out of the filling cavity 10, the elastic member 71 resets to make the valve core 72 and the water outlet hole 6 in a normally closed state, ensuring that the treated water will not flow back into the filling cavity 10. A sealing ring 74 is provided between the valve core 72 and the inner wall of the upper cover 93 to ensure that the water outlet hole 6 is closed when the valve core 72 is in the normally closed state, and to ensure that the water cannot flow back into the filling cavity 10.

[0048] Embodiment Two:

[0049] Except that the flexible material body 22 is set to be granular, such as Figure 7 As shown in the figure, in this embodiment, the flexible material body 22 can also be set to be in the shape of a plug located at one end of the filling cavity 10 away from the water outlet 4. The plug-shaped flexible material body 22 can provide a larger deformation amount, so that the water treatment material particles 21 can obtain a longer-term pre-tightening force, thereby better supporting the water treatment material particles 21 in the long term, providing a stable long-term supporting effect for the water treatment material particles 21, ensuring that the water treatment material particles 21 will not be washed away due to excessive water pressure during the water treatment process, making the gap between the water treatment material particles 21 in the filling cavity 10 smaller, ensuring the mutual fixing state between the water treatment material particles 21, further reducing the wear of the water treatment material particles 21, and effectively reducing the risks such as breakage and pulverization of the water treatment material particles 21. The plug-shaped flexible material body 22 only contacts a small part of the water treatment material particles 21, ensuring that the water treatment material particles 21 have a large enough total surface area to contact water, and effectively reducing the influence of the flexible material body 22 on the water treatment efficiency and treatment effect.

[0050] Among them, the filling cavity 10 can be set as a columnar space, and the end face of the flexible material body 22 abuts against the water treatment material particles 21 to ensure the stability of the flexible material body 22. Moreover, the columnar space can provide a larger capacity, enabling the filling cavity 10 to accommodate more water treatment material particles 21 and flexible material bodies 22, improving the water treatment efficiency. The opening of the columnar space is relatively large, facilitating the regular replacement and flushing of the internal flexible material body 22 and water treatment material particles 21.

[0052] Embodiment Three:

[0053] The present invention also provides a water-using household appliance, including a water inlet pipe, which is connected to the water treatment device in the above-mentioned embodiment. The life of the water treatment material particles 21 is greatly improved, and the frequency of replacing the water treatment material particles 21 is reduced, thereby extending the service life of the water-using household appliance, greatly reducing the user's usage cost, protecting the water-using household appliance, and extending the service life of the water-using household appliance. The water treatment device can pre-treat the water to achieve scale prevention, scale removal, antibacterial, sterilization, mineralization and disinfection, thereby protecting the water-using household appliance, extending the service life of the water-using household appliance, and providing protection for the user's water safety.
