Description
Technical Field
[0001] The invention relates to the technical field of water purification equipment, and specifically provides a water leakage protection device and a water purifier. Background Art
[0002] With the rapid development of the water purification industry and people's constant pursuit of a healthy and better life, there are more and more water purifier products, and as a result, there are more and more water leakage incidents. Traditional water leakage protectors mainly rely on water-absorbing and expanding cotton as detection elements. When a water leakage occurs, the expanding cotton absorbs water and expands in volume, and then pushes open the fixed cover at the end of the valve core, causing the valve core to move and finally close the water channel, thereby achieving the function of water leakage protection.
[0003] However, after using the water-absorbing and swelling cotton once, it is often impossible to restore to its original state due to its water-absorbing and swelling characteristics. Therefore, it must be replaced with a new swelling cotton before it can be used again. This not only increases the user's cost of use, but also brings the trouble of frequent replacement, reducing the convenience of the device and the user's experience. In addition, the replacement of the water-absorbing and swelling cotton may be difficult for ordinary users. If it is not replaced properly, it may also cause the water leakage protector to not work properly, thereby increasing the risk of water leakage.
[0004] The art needs a water leakage protection device and a water purifier to solve the above technical problems. Summary of the invention
[0005] The present invention aims to solve the above technical problem that the water-swellable cotton in the prior art needs to be replaced after each use, thereby causing many problems such as increased costs and inconvenient operation.
[0006] In a first aspect, the present invention provides a water leakage protection device, the water leakage protection device comprising a valve body, a connecting assembly and a floating assembly,
[0007] The valve body is provided with a water flow passage and a valve core inside, and the valve core is used to control the connection or closing of the water flow passage.
[0008] The connecting components are respectively connected to the valve core and the floating component.
[0009] When water leakage occurs, the floating assembly drives the valve core to move through the connecting assembly, thereby closing the water flow path.
[0010] In a specific embodiment of the above water leakage protection device, the water leakage protection device further includes a substrate,
[0011] The substrate is disposed between the water flow passage and the connecting component.
[0012] The substrate is provided with a connecting hole,
[0013] The valve core passes through the communicating hole and is connected to the connecting assembly.
[0014] In a specific embodiment of the water leakage protection device, a fixing member is provided on the substrate.
[0015] The fixing member is arranged at one end of the substrate close to the connecting component.
[0016] The connecting component is in contact with the fixing component, and the connecting component can rotate around the fixing component.
[0017] In a specific embodiment of the water leakage protection device, the connecting assembly includes a first rotating member and a second rotating member.
[0018] The first rotating member includes a connecting end, a first linkage end and an abutting end.
[0019] In a normal state, the connecting end is connected to the first end of the valve core, the first linkage end is overlapped on the upper side of the second rotating member, and the abutting end abuts against the fixing member.
[0020] The second rotating member includes a connecting rod and a second linkage end,
[0021] In a normal state, the connecting rod is connected to the floating assembly, and the second linkage end overlaps the first linkage end to maintain the overall balance of the first rotating member and the second rotating member.
[0022] In a specific embodiment of the water leakage protection device, the first rotating member further includes a first connecting shaft, and the second rotating member further includes a second connecting shaft.
[0023] When water leakage occurs, the floating assembly moves upward, and the connecting rod rotates around the fixing member through the second connecting shaft, so that the second linkage end loses the overlapping effect with the first linkage end, and the first rotating member rotates around the first connecting shaft to move the valve core, thereby closing the water flow path.
[0024] In the specific implementation of the above water leakage protection device, an elastic member is further provided in the valve body.
[0025] The elastic member is sleeved on the outside of the valve core.
[0026] The valve core is provided with a mounting groove.
[0027] One end of the elastic member is in contact with the base plate, and a portion of the elastic member is disposed in the mounting groove.
[0028] In a specific embodiment of the water leakage protection device, the water flow path includes a first flow path and a second flow path connected to each other.
[0029] The valve body is provided with a water inlet and a water outlet, wherein the first flow channel is communicated with the water inlet, and the second flow channel is communicated with the water outlet.
[0030] The valve core is arranged in the first flow channel,
[0031] In a normal state, there is a gap between the second end of the valve core and the end of the second flow channel, so that the water flow channel is connected.
[0032] When water leakage occurs, the connecting assembly drives the second end of the valve core to move to block the second flow channel, thereby closing the water flow channel.
[0033] In a specific implementation of the above-mentioned water leakage protection device, the cross-sectional diameter of the valve core is larger than the caliber of the second flow channel, so that in a water leakage state, the valve core can completely block the second flow channel.
[0034] In a specific embodiment of the water leakage protection device, the floating assembly includes a buoyancy member and a counterweight member.
[0035] The counterweight is arranged on the upper part of the buoyancy member.
[0036] The connecting assembly is respectively connected to the valve core and the buoyancy member.
[0037] In the case of adopting the above technical solution, the water leakage protection device provided by the present invention includes a valve body, a connecting assembly and a floating assembly, a water flow path and a valve core are arranged inside the valve body, the valve core is used to control the connection or closing of the water flow path, and the connecting assembly is respectively connected to the valve core and the floating assembly. Based on the above structural setting, the water flow path of the water leakage protection device is connected in a normal state, so as to facilitate the use of the user. When a water leakage occurs, the floating assembly moves upward under the action of the water leakage, and then drives the valve core to move through the connecting assembly, so that the water flow path is closed to prevent the water leakage from continuing to occur. At the same time, after maintenance, the water inside the water leakage protection device is cleared, the floating assembly is reset, and then the valve core is reset, and the water flow path continues to be connected.
[0038] Furthermore, the water leakage protection device provided by the present invention defines a substrate, which is used to block one side of the valve body and clamp the valve core to enhance the stability and aesthetics of the water leakage protection device.
[0039] Furthermore, the water leakage protection device provided by the present invention defines a fixing member, which is used to abut the connecting component. When water leakage occurs, the floating component moves upward, thereby driving the connecting component to rotate around the fixing member, thereby pushing the valve core to close the water flow path.
[0040] Furthermore, the water leakage protection device provided by the present invention defines a connecting component including a first rotating member and a second rotating member, wherein the second rotating member is used to connect with the floating component and rotate when the floating component moves upward. Since the first rotating member and the second rotating member are in an overlapping state, when the second rotating member rotates, the overlapping state disappears, causing the first rotating member to lose its steady state, so that the first rotating member rotates around the fixed member, thereby pushing the valve core to close the water flow path.
[0041] Furthermore, the water leakage protection device provided by the present invention also defines a first connecting shaft and a second connecting shaft, wherein the first connecting shaft and the second connecting shaft are respectively used to realize the rotation of the first rotating member and the second rotating member.
[0042] Furthermore, the water leakage protection device provided by the present invention defines an elastic part. Under normal conditions, the elastic part is fixed between the base plate and the mounting groove and is in a compressed state to produce elastic deformation. When water leakage occurs, the connecting assembly pushes the valve core to move, and the elastic part rebounds to produce a driving force, which is beneficial for the valve core to block the water flow path.
[0043] Furthermore, the water leakage protection device provided by the present invention defines a first flow channel and a second flow channel. Under normal conditions, water flows into the valve body through the water inlet, flows through the first flow channel and the second flow channel in sequence, and flows out through the water outlet. When water leakage occurs, the valve core blocks the end of the second flow channel, and the water cannot flow into the second flow channel, thereby achieving the closure of the water flow channel.
[0044] Furthermore, the water leakage protection device provided by the present invention also limits the cross-sectional diameter of the valve core to be larger than the caliber of the second flow channel, so as to ensure that the valve core can completely block the second flow channel to ensure that water leakage does not continue.
[0045] Furthermore, the water leakage protection device provided by the present invention also defines a buoyancy member and a counterweight member, so that when the buoyancy member moves upward due to buoyancy, the movement speed of the buoyancy member is slow, thereby preventing the buoyancy member from moving upward too quickly and causing damage to the connecting assembly and the valve core.
[0046] In a second aspect, the present invention further provides a water purifier, which includes the water leakage protection device described in the above embodiment. BRIEF DESCRIPTION OF THE DRAWINGS

These terms are mainly intended to better describe the embodiments of the present disclosure and their embodiments, and are not intended to limit the indicated devices, elements or components to have a specific direction, or to be constructed and operated in a specific direction.

[0058] With the rapid development of the water purification industry and people's constant pursuit of a healthy and beautiful life, there are more and more water purifier products, and the number of water leakage incidents is also increasing. Traditional water leakage protectors mainly rely on water-absorbing and expanding cotton as detection elements. When a water leak occurs, the expanding cotton absorbs water and expands in volume, and then pushes open the fixed cover at the end of the valve core, causing the valve core to move and eventually close the water path, thereby achieving the function of water leakage protection. However, after using the water-absorbing and expanding cotton once, due to its water-absorbing and expanding characteristics, it is often impossible to restore to its original state. Therefore, a new expansion cotton must be replaced before it can continue to be used. This not only increases the user's cost of use, but also brings the trouble of frequent replacement, reducing the convenience of the equipment and the user's experience. In addition, the replacement operation of the water-absorbing and expanding cotton may be difficult for ordinary users. If it is not replaced properly, it may also cause the water leakage protector to fail to work properly, thereby increasing the risk of water leakage.
[0059] First, combine Figure 1 and Figure 2 The present invention provides a water leakage protection device, which includes a valve body 1, a connecting component 2 and a floating component 3. A water flow path 11 and a valve core 12 are arranged inside the valve body 1. The valve core 12 is used to control the connection or closing of the water flow path 11. The connecting component 2 is connected to the valve core 12 and the floating component 3 respectively. When water leakage occurs, the floating component 3 drives the valve core 12 to move through the connecting component 2, so that the water flow path 11 is closed.
[0060] Based on the above structural setting, the valve body 1 is the main part of the water leakage protection device, which includes key components such as the water flow path 11 and the valve core 12. The water flow path 11 is the channel through which the water flows, and the valve core 12 is responsible for controlling the on and off of the water flow. Under normal circumstances, the valve core 12 of the water leakage protection device remains in an open state, allowing the water flow to pass smoothly for the convenience of users; when a water leakage is detected, the floating component 3 moves upward under the action of the water leakage, and then drives the valve core 12 to move through the connecting component 2, so that the water flow path 11 is closed to prevent the water leakage from continuing to occur. At the same time, after maintenance, the water inside the water leakage protection device is cleared, the floating component 3 is reset, and then the valve core 12 is reset, and the water flow path 11 continues to be connected. It should be noted that the present invention does not impose any restrictions on the specific dimensions of the valve body 1, the connecting component 2 and the floating component 3, and those skilled in the art can set them according to actual use requirements.
[0061] In this preferred embodiment, the water leakage protection device provided by the present application also includes a substrate 4, which is arranged between the water flow passage 11 and the connecting component 2, and a connecting hole 41 is arranged on the substrate 4, and the valve core 12 is connected to the connecting component 2 through the connecting hole 41. The main function of the substrate 4 is to provide a stable support platform for fixing and supporting the valve core 12 and other related components. At the same time, the substrate 4 is also connected to the valve core 12 through the connecting hole 41 thereon to ensure that the water flow can smoothly pass through the water leakage protection device. In addition, the substrate 4 can also be used to block one side of the valve body 1 to prevent the water flow from leaking out from unnecessary parts, which is conducive to improving the overall sealing and stability of the water leakage protection device. The substrate 4 can also be clamped to the valve core 12 to ensure that the valve core 12 will not loosen or fall off during installation and use. This further enhances the reliability and safety of the water leakage protection device. It should be noted that the present invention does not impose any restrictions on the specific structure and setting size of the substrate 4, and those skilled in the art can set it according to actual use requirements.
[0062] In this preferred embodiment, a fixing member 42 is provided on the substrate 4, and the fixing member 42 is provided at one end of the substrate close to the connecting component 2, and the connecting component 2 abuts against the fixing member 42, and the connecting component 2 can rotate around the fixing member 42. Under normal conditions, the water flow passage 11 is open, allowing water to flow through; when water leakage occurs, the water level rises, and the floating component 3 moves upward accordingly, and the movement of the floating component 3 drives the connecting component 2 to rotate around the fixing member 42, and the rotation of the connecting component 2 further drives the valve core 12, thereby closing the water flow passage 11, thereby preventing the continued leakage of water. Therefore, the water leakage protection device provided by the present application not only improves the degree of automation, but also ensures that the water source can be quickly and effectively cut off when water leakage occurs, preventing further losses. It should be noted that the present invention does not impose any restrictions on the specific structure and setting size of the fixing member 42, and only needs to meet the fixing member 42 can abut against the connecting component 2, and those skilled in the art can set it according to actual use requirements.
[0063] In this preferred embodiment, see Figure 3 , Figure 3 Schematic diagram of the structure of the connection components in the water leakage protection device provided by the present invention. Figure 3 As shown, the connecting component 2 includes a first rotating member 21 and a second rotating member 22, the first rotating member 21 includes a connecting end 211, a first linkage end 212 and an abutting end 213, in a normal state, the connecting end 211 is connected to the first end 121 of the valve core 12, the first linkage end 212 is overlapped on the upper side of the second rotating member 22, and the abutting end 213 is abutted against the fixing member 42, the second rotating member 22 includes a connecting rod 221 and a second linkage end 222, in a normal state, the connecting rod 221 is connected to the floating component 3, and the second linkage end 222 is overlapped with the first linkage end 212 to maintain the overall balance of the first rotating member 21 and the second rotating member 22. Among them, the second rotating member 22 is used to connect with the floating component 3, and rotates when the floating component 3 moves upward. Since the first rotating member 21 and the second rotating member 22 are in an overlapping state, when the second rotating member 22 rotates, the overlapping state disappears, causing the first rotating member 21 to lose its steady state, so that the first rotating member 21 rotates around the fixed member 42, thereby pushing the valve core 12 to close the water flow path 11.
[0064] In this preferred embodiment, the first rotating member 21 further includes a first connecting shaft 214 , and the second rotating member 22 further includes a second connecting shaft 223 . The first connecting shaft 214 and the second connecting shaft 223 are respectively used to realize the rotation of the first rotating member 21 and the second rotating member 22 .
[0065] Specifically, under normal conditions, the connecting end 211 is connected to the first end 121 of the valve core 12, the abutting end 213 abuts against the fixing member 42, the connecting rod 221 is connected to the floating component 3, and the second linkage end 222 overlaps with the first linkage end 212 to maintain the overall balance of the first rotating member 21 and the second rotating member 22. At this time, the water flow path 11 is open, allowing water to flow through; when water leakage occurs, the water level rises, and the floating component 3 moves upward accordingly. The movement of the floating component 3 drives the connecting rod 221 to rotate around the fixing member 42 through the second connecting shaft 223, thereby causing the second linkage end 222 to lose the overlapping effect with the first linkage end 212, and the first rotating member 21 rotates around the first connecting shaft 214. The rotation of the connecting component 2 further pushes the valve core 12, thereby closing the water flow path 11, thereby preventing further leakage of water.
[0066] In this preferred embodiment, combined with Figures 1 to 3 , an elastic member 13 is also provided in the valve body 1, and the elastic member 13 is sleeved on the outside of the valve core 12. The valve core 12 is provided with a mounting groove 123, one end of the elastic member 13 abuts against the substrate 4, and the elastic member 13 is partially provided in the mounting groove 123. Specifically, under normal conditions, the elastic member 13 is fixed between the substrate 4 and the mounting groove 123, and is in a compressed state to produce elastic deformation. When water leakage occurs, the connecting assembly 2 pushes the valve core 12 to move, and the elastic member 13 rebounds to produce a driving force, which is beneficial for the valve core 12 to block the water flow path 11. It should be noted that the present invention does not impose any restrictions on the specific structure and setting type of the elastic member 13, and those skilled in the art can set it according to actual use requirements. Optionally, the elastic member 13 can be a spring.
[0067] In this preferred embodiment, the water flow path 11 includes a first flow channel 111 and a second flow channel 112 that are connected, and the valve body 1 is provided with a water inlet 14 and a water outlet 15, wherein the first flow channel 111 is connected to the water inlet 14, and the second flow channel 112 is connected to the water outlet 15, and the valve core 12 is arranged in the first flow channel 111. Under normal conditions, there is a gap between the second end 122 of the valve core 12 and the end of the second flow channel 112, and water flows into the valve body 1 through the water inlet 14, flows through the first flow channel 111 and the second flow channel 112 in sequence, and flows out through the water outlet 15, so that the water flow path 11 is connected; when water leakage occurs, the connecting component 2 drives the second end 122 of the valve core 12 to move to block the second flow channel 112. Since the valve core 12 blocks the end of the second flow channel 112, water cannot flow into the second flow channel 112, so that the water flow path 11 can be closed, thereby preventing the water from continuing to leak.
[0068] In this preferred embodiment, the cross-sectional diameter of the valve core 12 is larger than the caliber of the second flow channel 112, so that in the water leakage state, the valve core 12 can completely block the second flow channel 112. It can be understood that in this embodiment, the cross-sectional shapes of the valve core 12 and the second flow channel 112 are both circular, and the cross-sectional diameter of the valve core 12 and the caliber of the second flow channel 112 refer to the circular diameters of the valve core 12 and the second flow channel 112 in the direction perpendicular to the water flow, respectively. The above design can ensure that when the valve core 12 contacts the second flow channel 112, an effective seal can be formed, thereby ensuring that the water flow is completely blocked in the water leakage state to prevent any leakage.
[0069] In this preferred embodiment, the floating assembly 3 includes a buoyancy member 31 and a counterweight member 32. The counterweight member 32 is arranged on the upper part of the buoyancy member 31. The connecting assembly 2 connects the valve core 12 and the buoyancy member 31 respectively. The buoyancy member 31 is the core part of the floating assembly 3, which is responsible for generating buoyancy in the water, thereby driving the entire floating assembly 3 to rise. Optionally, the buoyancy member 31 can be made of a material with a density lower than that of water, such as foam plastics, rubber, etc. The counterweight member 32 is arranged on the upper part of the buoyancy member 31, and its main function is to adjust the rising speed of the buoyancy member 31. By adding the counterweight, the rising speed of the buoyancy member 31 when it is acted upon by buoyancy can be slowed down to prevent it from moving too fast. When the buoyancy member 31 is affected by the buoyancy of water, it will move upward. Due to the presence of the counterweight member 32, the rising speed of the buoyancy member 31 will be slowed down, making the rising process smoother, thereby preventing the buoyancy member 31 from moving up too quickly and impacting the connecting component 2 and the valve core 12, thereby preventing the connecting component 2 or the valve core 12 from being damaged or misaligned, thereby affecting the normal operation of the entire device.
[0070] In this preferred embodiment, the connecting component 2 also includes a supporting member 23, which is located at the end of the connecting component 2 and is arranged on the upper part of the buoyancy member 31, for supporting the counterweight member 32 to prevent the counterweight member 32 from slipping and falling during the rising process of the buoyancy member 31.
[0071] On the other hand, the present invention further provides a water purifier, which includes the water leakage protection device as described in the above embodiment.
[0072] Based on the above structural setting, under normal circumstances, the valve core 12 of the water purifier remains in an open state, allowing water to flow smoothly, so as to facilitate user use; when water leakage is detected, the floating component 3 moves upward under the action of the water leakage, and then drives the valve core 12 to move through the connecting component 2, so that the water flow path 11 is closed to prevent further leakage. At the same time, after maintenance, the water inside the water leakage protection device is cleared, the floating component 3 is reset, and then the valve core 12 is reset, and the water flow path 11 continues to be connected, without the need for manual replacement of parts, which is convenient for users to use.
[0073] It should be noted that the above-mentioned implementation mode is only used to illustrate the principle of the present invention and is not intended to limit the scope of protection of the present invention. Without departing from the principle of the present invention, those skilled in the art can adjust the above-mentioned structure so that the present invention can be applied to more specific application scenarios.
[0074] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
