Description

Technical Field

[0001] The present invention relates to the technical field of water purification equipment, and in particular to a filtering device with a one-time trigger identification device reset. Background Art

[0002] Water purifiers usually use filters to filter impurities in water to achieve water purification. Due to the limited service life of the filter, the filter needs to be replaced regularly during the actual water purification process. After replacing the new filter, the control system on the water purifier needs to be reset so that the water purifier can re-identify the new filter and start the new filter's service life to ensure the accuracy of the filter replacement cycle. In existing water purifiers, after replacing the new filter, it is necessary to use an additional tool to press the electronic switch to trigger the control system in the water purifier so that the control system can re-identify and calculate the service life of the new filter; however, using an additional tool to start the electronic switch is more troublesome in actual operation, and the electronic switch is precise. If non-professional technicians use tools to operate, it will increase the safety risk and risk of misoperation of the water purifier, which may easily cause damage to the water purifier.

[0035] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Embodiment 1:

[0037] See also Figure 1—9. The present invention provides a filtering device capable of triggering the reset of an identification device once, comprising a filter element assembly 1 and a reset device 2 for triggering the reset of an identification device 3. The reset device 2 can be raised and lowered between the filter element assembly 1 and the identification device 3. An invalidation structure 213 is provided in the reset device 2. The filter element assembly 1 drives the reset device 2 to move downward and connect with the identification device 3 to trigger the identification device 3 to re-identify the filter element assembly 1. The invalidation structure 213 is used to limit the reset device 2 from triggering the identification device 3 for the second time. The reset device 2 is also connected to an elastic member 5, and the elastic member 5 is used to move the reset device 2 upward and reset it. In this embodiment, the filter element assembly 1 can be understood as an independent and directly replaceable filter element provided in the filter device of the water purifier. The reset device 2 and the identification device 3 are sequentially provided at the lower part of the filter element assembly 1. The identification device 3 can be an identification switch, one end of which is opposite to the reset device 2 and the other end is electrically connected to the circuit board of the water purifier, so that the identification device 3 is electrically connected to the control system of the water purifier through the circuit board; after the user replaces the filter element assembly 1, the user manually presses the filter element assembly 1 to move downward, and the reset device 2 is pushed downward by the filter element assembly 1, so that The reset device 2 contacts the identification device 3 to trigger the identification device 3 to reset and re-identify the new filter element assembly 1, so that the control system of the water purifier can recognize the new filter element and recalculate the service life of the new filter element. During the downward movement of the reset device 2, the reset device 2 is actively disabled by the failure structure 213 to avoid the reset device 2 being triggered for the second time by the force of the downward movement of the filter element assembly 1, thereby preventing the control system of the water purifier from repeatedly identifying the new filter element, so as to ensure the accuracy of the calculation of the filter element service life cycle by the control system of the water purifier. In addition, the user can directly manually press the filter element assembly 1 to drive the reset device 2 to move downward and connect with the identification device 3, thereby triggering the identification device 3 to reset. The reset device 2 is moved upward and reset through the elastic member 5 after the identification device 3 is triggered, so that the reset device 2 is disconnected from the identification device 3, ensuring that the reset device 2 triggers the identification device 3 once. After replacing the new filter element assembly, the user manually presses the filter element assembly 1 to trigger the reset of the identification device 3 through the reset device 2, so that the control system of the water purifier recognizes the new filter element and recalculates the usage time of the new filter element. There is no need to use additional tools to start the identification device 3. The operation is simple and convenient. Even if it is operated by non-professional technicians, it is not easy to damage the water purifier, which can effectively protect the safety of the water purifier.

[0038] For details, see Figure 4—5. A mounting groove 11 is provided in the filter element assembly 1. The reset device 2 includes a trigger member 21 provided in the mounting groove 11 and a reset member 22 provided at the lower part of the trigger member 21. The reset member 22 at least partially extends into the mounting groove 11. The failure structure 213 is provided in the trigger member 21. In this embodiment, the filter element assembly 1 at least includes a filter bottle and a filter element provided in the filter bottle. The bottom of the filter bottle is recessed upward to form the mounting groove 11. The trigger member 21 is cooperatively installed in the mounting groove 11. During assembly, the reset member 22 at least partially extends into the mounting groove 11 and is opposite to the reset member 22. The identification device 3 is provided at the lower part of the reset member 22 and is opposite to the reset member 22. Optionally, see Figure 5 In the figure, H1 represents the depth of the installation groove 11, and H2 represents the total height of the extending parts of the trigger member 21 and the reset member 22. In order to avoid the identification device 3 being improperly triggered due to user's misoperation, the depth of the installation groove 11 is set to be greater than the total height of the extending parts of the trigger member 21 and the reset member 22, that is, when the trigger member 21 is installed in the installation groove 11 and the reset member 22 is extended into the installation groove 11, the top of the reset member 22 is close to or in contact with the bottom of the trigger member 21, and a gap is formed between the top of the trigger member 21 and the inner top surface of the installation groove 11. When the filter element assembly 1 is not subjected to external force, the trigger member 21 will not be subjected to the downward force of the filter element assembly 1, and no relative displacement will occur between the trigger member 21 and the reset member 22, so the identification device 3 will not be triggered and started. When the filter element assembly 1 is replaced, the user presses the new filter element assembly 1 downward to drive the trigger member 21 to move downward and continuously approach the reset member 22, so that the trigger member 21 can push the reset member 22 and make the reset member 22 move downward and continuously approach the identification device 3, and finally contact the identification device 3 through the reset member 22 to trigger the identification device 3 to reset and re-identify the new filter element assembly 1. It should be noted that, during the production process of the filter device, the trigger member 21 is installed in the installation groove 11. When the user replaces the filter element assembly 1, there is no need to remove the trigger member 21 separately, which is equivalent to the trigger member 21 and the filter element assembly 1 being the same component for daily consumption; when the user replaces the new filter element assembly 1 and triggers the identification device 3 to reset through the reset device 2, the reset device 2 actively fails through the failure structure 213; when the user replaces the old filter element assembly 1, the failed trigger member 21 is replaced synchronously with the old filter element assembly 1. Since the trigger member 21 is a disposable trigger component, when the user replaces the old filter element assembly 1, the state of the failure structure 213 can be used to determine whether the filter element assembly 1 successfully triggered the reset of the identification device 3 when it was last replaced, so that the user can timely adjust the reset operation of the identification device 3 after the filter element is replaced.

[0039] For further information, see Figure 6 —8, the trigger member 21 includes a first shell 211 and a first push rod 212, the failure structure 213 is arranged between the first shell 211 and the first push rod 212, and the reset member 22 is arranged at the lower part of the first push rod 212. The first shell 211 is pressed by the filter element assembly 1, so that the first shell 211 can drive the first push rod 212 to move downward and push the reset member 22 through the failure structure 213, so that the reset member 22 triggers the identification device 3, and the failure structure 213 is actively failed by the downward movement of the first shell 211 to limit the first shell 211 from driving the first push rod 212 to push the reset member 22 for a second time. Furthermore, the first shell 211 is provided with a first inner cavity 2111 capable of accommodating the first push rod 212, and a boss 2112 located at the lower part of the first inner cavity 2111, the boss 2112 is provided with a through hole 2113 connected to the first inner cavity 2111, and the failure structure 213 is arranged between the boss 2112 and the first push rod 212; the first push rod 212 includes a rod head 2121 and a rod shaft 2122 connected to each other, the rod head 2121 is placed in the first inner cavity 2111, and the rod shaft 2122 passes through the through hole 2113 and is opposite to the reset member 22. Furthermore, the first shell 211, the failure structure 213 and the first push rod 212 are an integrally formed structure, and the failure structure 213 includes a plurality of protrusions 2131 provided on the boss 2112 and extending toward the through hole 2113, and a connecting portion 2132 provided between each of the protrusions 2131 and the rod body 2122, and each of the connecting portions 2132 can be disconnected by the force of the downward movement of the first shell 211, so as to limit the first shell 211 from driving the first push rod 212 to push the reset member 22 for a second time.

[0040] In this embodiment, the first shell 211 is mounted in the mounting groove 11, and a first inner cavity 2111 is longitudinally penetrated in the first shell 211. At least the bottom end of the first inner cavity 2111 is connected to the outside, or both ends of the first inner cavity 2111 can be connected to the outside. A boss 2112 is also provided at the bottom of the first shell 211, and the boss 2112 radially extends from the inner wall of the first shell 211 toward the first inner cavity 2111, and a through hole 2113 connected to the first inner cavity 2111 is formed in the boss 2112. Furthermore, the first push rod 212 is placed in the first inner cavity 2111 and the rod body 2122 passes through the through hole 2113 and extends out of the lower part of the first shell 211, and the rod body 2122 is connected to the boss 2112 through the connecting portion 2132. In this embodiment, the trigger member 21 is an integrally formed structure, that is, the first push rod 212 is integrally formed with the first shell 211 through the connecting portion 2132, wherein the boss 2112 is provided with a plurality of convex blocks 2131 distributed at equal intervals along the circumferential direction, each of the convex blocks 2131 radially extends from the inner wall of the boss 2112 toward the center of the through hole 2113, and each of the convex blocks 2131 can be set as a cone, that is, each of the convex blocks 2131 The root width gradually decreases toward its end, the root is the connection between the protrusion 2131 and the boss 2112, and the end is one end of each protrusion 2131 close to the rod body 2122, wherein the ends of each protrusion 2131 are respectively connected to the rod body 2122 through a connecting portion 2132, and each connecting portion 2132 can be set as a connecting piece with a thinner thickness or a connecting strip with a smaller diameter; when the user presses the filter element assembly 1 to drive the first housing 211 to drive the first push rod 212 to move downward and push the reset member 22, so that the reset member 22 moves downward and triggers the identification device 3, and the trigger member During the downward movement of the filter element 21, the first shell 211 is forced to move downward relative to the first push rod 212, so that the connecting part 2132 between each protrusion 2131 and the rod body 2122 is easily disconnected, so that the failure structure 213 actively fails, and the trigger member 21 triggers the reset member 22 once, that is, the reset device 2 triggers the identification device 3 once, so as to avoid the reset device 2 being triggered for the second time by the force of the downward movement of the filter element assembly 1, thereby preventing the control system of the water purifier from repeatedly identifying the new filter element, so as to ensure the accuracy of the calculation of the filter element usage cycle by the control system of the water purifier.It should be noted that the thickness of the connecting piece forming the connecting portion 2132 or the diameter of the connecting strip forming the connecting portion 2132 can be set to 0.1-1 mm, and when the thickness or the diameter increases, the pressing force applied by the user to the filter element assembly 1 can also be increased accordingly, so that the connecting portion 2132 is easily disconnected by force, ensuring that the failure structure 213 can be actively failed; in addition, the trigger member 21 can be integrally formed of brittle materials. It should be noted that each of the protrusions 2131 can be set as a cone or a conical prism.

[0041] For further options, see Figure 6 —8. A matching hole 2133 is provided between any two protrusions 2131. A plurality of clamping blocks 2123 respectively matched with the matching holes 2133 are provided on the outer side of the rod head 2121. After the connecting portion 2132 is disconnected, the clamping blocks 2123 are correspondingly engaged with the matching holes 2133 to limit the first push rod 212 from being separated from the first shell 211. In this embodiment, the matching hole 2123 is connected to the first inner cavity 2111 and the through hole 2113. When the failure structure 213 fails, that is, the connecting portion 2132 between the rod body 2122 and each of the protrusions 2131 is disconnected, the first push rod 212 will automatically move downward relative to the first shell 211 under the action of gravity. In order to prevent the first push rod 212 from being separated from the first shell 211 and causing the first push rod 212 to fall easily, a plurality of the blocking blocks 2123 are arranged on the outer side of the rod head 2121, and each of the blocking blocks 2123 is evenly spaced along the outer circle direction of the rod head 2121 and corresponds to each of the matching holes 2133. When the first push rod 212 moves downward relative to the first shell 211 under gravity, the first push rod 212 can be automatically moved downward relative to the first shell 211 through each of the blocking blocks 2123. The block 2123 is correspondingly engaged with each of the matching holes 2133 to fix the first push rod 212 in the first shell 211, thereby preventing the first push rod 212 from being separated from the first shell 211, ensuring the overall integrity of the trigger member 21, and making it convenient for the user to replace the filter element assembly 1 and the trigger member 21 at the same time. When the user removes the old filter element assembly 1, the user can manually push the first push rod 212 from the bottom of the old filter element assembly 1. If the first push rod 212 can move toward the first inner cavity 2111 relative to the first shell 211, it means that the connection portion 2132 between the first push rod 212 and the first shell 211 has been disconnected, otherwise it has not been disconnected, thereby judging whether the identification device 3 was successfully triggered to reset when the filter element assembly 1 was last replaced.

[0042] Optional, see Figure 1 , 24. The filtering device also includes a substrate 4 for mounting the identification device 3. The reset device 2 is connected between the filter element assembly 1 and the substrate 4. A first sliding connection portion 221 is provided at the bottom of the reset device 2. A second sliding connection portion 41 is provided in the substrate 4. The first sliding connection portion 221 is correspondingly connected to the second sliding connection portion 41 so that the reset device 2 can be raised and lowered and connected to the substrate 4. The elastic member 5 is provided between the reset device 2 and the substrate 4. Specifically, in the present embodiment, the filter element assembly 1, the reset device 2 and the identification device 3 can be installed in the water purifier through the substrate 4, wherein the identification device 3 is fixedly installed in the substrate 4, and the upper end of the identification device 3 is placed on the upper part of the substrate 4, and the lower end of the identification device 3 is passed through the lower side of the substrate 4 and is electrically connected to the circuit board of the water purifier.

Further, the connecting rod 2211 has elastic deformation characteristics, and the bottom of each clamping block 2212 is provided with a guide portion 2213, and the guide portion 2213 is used to guide the connecting rod 2211 to insert into the clamping hole 411. During assembly, the connecting rod 2211 is clamped with the clamping hole 411 through the guide portion 2213, so that the reset member 22 is installed on the substrate 4, and the reset member 22 can move up and down relative to the clamping hole 411 through the connecting rod 2211. The first sliding connection portion 221 and the second sliding connection portion 41 have simple structures and are easy to produce and implement. It should be noted that the second inner cavity 2221 corresponds to the upper part 2201 of the second shell 222, and the third inner cavity 2222 corresponds to the lower part 2202 of the second shell 222. The outer diameter of the upper part 2201 of the second shell 222 is smaller than the port inner diameter of the mounting groove 11 to ensure that the upper part 2201 of the second shell 222 can extend into the mounting groove 11, and the outer diameter of the lower part 2202 of the second shell 222 can be larger than the outer diameter of the upper part 2201 of the second shell 222.

[0044] Furthermore, the elastic member 5 is arranged between the reset member 22 and the base plate 4. Specifically, the elastic member 5 is arranged in the third inner cavity 2222 and sleeved on the outer side of the identification device 3; when the user presses the filter element assembly 1 to drive the trigger member 21 to move downward, the first shell 211 drives the first push rod 212 to move downward and pushes the reset member 22 through the first push rod 212, so that the reset member 22 moves downward and contacts the identification device 3 to trigger the identification device 3 to reset. During the movement, the elastic member 5 is compressed by force. When the identification device 3 completes the reset, that is, the identification device 3 has triggered the water purifier control system to re-recognize the new filter element, the reset member 22 is moved upward relative to the identification device 3 by the rebound force of the elastic member 5, so that the reset member 22 is away from the identification device 3 and disconnected from the contact connection with the identification device 3. When the reset member 22 is reset by the upward movement of the elastic member 5, the reset member 22 can reversely push the first push rod 212 to move upward relative to the first shell 211. Optionally, the elastic member 5 is a reset spring.

[0046] The difference between the second embodiment and the first embodiment is that the specific implementation of the failure structure 213 in the trigger member 21 is different, see Fig.10—14, the failure structure 213 includes an elastic claw portion 2134 arranged on the upper part of the boss 2112 and placed in the first inner cavity 2111, and the elastic claw portion 2134 is used to clamp and fix the rod head 2121. When the first shell 211 is pressed by the filter element assembly 1 and moves downward relative to the first push rod 212, the elastic claw portion 2134 moves downward relative to the rod head 2121 to drive the first push rod 212 to move downward, and the elastic claw portion 2134 can produce elastic deformation toward the outside of the rod head 2121, so that the rod head 2121 can pass through the elastic claw portion 2134 upwards and the first push rod 212 is fixed in the elastic claw portion 2134. In the present embodiment, the first push rod 212 and the first shell 211 can be two separate parts, and the first push rod 212 and the first shell 211 are connected by the elastic claw portion 2134. Specifically, the elastic claw portion 2134 includes a plurality of elastic claws 21341 arranged on the top of the boss 2112 and extending upward along the first inner cavity 2111, and each of the elastic claws 21341 is evenly spaced along the circumferential direction of the top of the boss 2112, and a clamping space 21342 for clamping the rod head 2121 is formed between each of the elastic claws 21341; when the user presses the filter element assembly 1 to drive the first shell 211 to move downward, the first push rod 212 is driven downward by the first shell 211 and the reset member 22 is pushed downward by the first push rod 212, so that the reset member 22 contacts the identification device 3 and triggers the identification device 3 to reset the filter element. In the embodiment, the first shell 211 has a tendency to move downward relative to the first push rod 212, and each of the elastic claws 21341 moves downward relative to the rod head 2121 under the force of the downward movement of the first shell 211 and generates elastic deformation toward the outside of the rod head 2121, so that the rod head 2121 can pass through the upper part of the elastic claw portion 2134, and at the same time, the first push rod 212 is clamped and fixed in the first shell 211 by the elastic force of each of the elastic claws 21341. Since the clamping positions of each of the elastic claws 21341 relative to the first push rod 212 are different before and after the failure structure 213 fails, that is, before the failure structure 213 fails, the clamping positions of each of the elastic claws 21341 relative to the first push rod 212 are close to the top of the rod head 2121. For the convenience of description, the clamping positions of each of the elastic claws 21341 relative to the first push rod 212 before the failure structure 213 fails are named as initial positions (such as Fig.13After the failure structure 213 fails, the clamping position of each elastic claw 21341 relative to the first push rod 212 is located at the lower part of the initial position and away from the top of the rod head 2121, or even at the rod shaft 2122. For the convenience of description, the clamping position of each elastic claw 21341 relative to the first push rod 212 after the failure structure 213 fails is named as the failure position (as shown in FIG. Fig.14 As shown), after the failure structure 213 fails, the failure position is located at the lower part of the initial position, which is equivalent to the first push rod 212 moving upward along the first inner cavity 2111 relative to the first shell 211, so that the first push rod 212 is away from the reset member 22, increasing the distance between the trigger member 21 and the reset member 22, thereby achieving active failure of the trigger member 21 through the failure structure 213, so as to avoid the reset device 2 being triggered by the force of the filter element assembly 1 moving downward for the second time to trigger the identification device 3, thereby preventing the water purifier control system from repeatedly identifying a new filter element, so as to ensure the accuracy of the water purifier control system's calculation of the filter element usage cycle. It should be noted that in order to ensure that the elastic claw portion 2134 can clamp the first push rod 212, each of the elastic claws 21341 has an arc-shaped trend from the side wall of the boss 2112 toward the central axis of the first inner cavity 2111.

[0047] For further information, see Fig.13—15. A first limiting portion 2114 is also provided at the bottom of the first shell 211, and an opening 2115 is provided in the first limiting portion 2114. The bottom end of the rod body 2122 can pass through the opening 2115 and extend out of the lower part of the first shell 211. A second limiting portion 2124 is provided on the outer side of the rod body 2122, and the outer diameter of the second limiting portion 2124 is larger than the inner diameter of the opening 2115. When the elastic deformation performance of the elastic claw portion 2134 is weakened or lost, the elastic claw portion 2134 cannot clamp and fix the first push rod 212. The first push rod 212 can move downward relative to the first shell 211 under the action of gravity. At this time, the second limiting portion 2124 abuts against the upper part of the first limiting portion 2114 to limit the first push rod 212 from being separated from the first shell 211, effectively preventing parts from falling, thereby ensuring the overall integrity of the trigger member 21, and facilitating the user to directly replace the trigger member 21 while replacing the filter element assembly 1. It should be noted that the second limiting portion 2124 is fixedly connected to the bottom of the first shell 211, and the second limiting portion 2124 is interference fit with the mounting groove 11 so that the trigger member 21 can be installed in the mounting groove 11; when the user presses the filter element assembly 1, the first shell 211 and the first limiting portion 2114 are pushed downward in the mounting groove 11 by the filter element assembly 1, and the first push rod 212 is driven downward and pushed downward by the elastic claw portion 2134 to push the reset member 22, so that the reset member 22 is connected to the identification device 3 to trigger the identification device 3 to reset the filter element. During the downward movement of the trigger member 21, the first shell 211 and the first limiting portion 2114 have a tendency to move downward relative to the first push rod 212. At this time, the elastic claw portion 2134 is forced to deform toward the outside of the first push rod 212 so that the first push rod 212 passes through the elastic claw portion 2134 upward, thereby actively failing the failure structure 213.

[0048] The above examples are only used to further illustrate the technical content of the present invention, so that readers can understand it more easily, but they do not mean that the implementation of the present invention is limited to this. Any technical extension or re-creation made according to the present invention is protected by the present invention. The protection scope of the present invention shall be subject to the claims.
