DETAILED DESCRIPTION

[0040] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0042] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present invention. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0043] Please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the exploded structure of a water purification device provided in an embodiment of the present application. Figure 2 This is a schematic diagram of the exploded structure of another water purification device provided in an embodiment of the present application. Figure 3 yes Figure 2 The water purification device may include: a body 100, a drive telescopic assembly 200 and a filter element assembly 300.

[0044] The body 100 of the water purification device may have a water hole 101 .

[0045] The driving telescopic assembly 200 in the water purification device can be located on one side of the water hole 101 and can be detachably connected to the body 100 , and the driving telescopic assembly 200 can have a water passage 201 that cooperates with the water hole 101 .

[0046] The filter element assembly 300 in the water purification device can be located on the side of the drive telescopic assembly 200 away from the water hole 101 and movably connected to the drive telescopic assembly 200. The filter element assembly 300 can have a water channel 301 connected to the water channel 201. The filter element assembly 300 can be detachably connected to the body 100.

[0047] Among them, the driving telescopic assembly 200 has a first state and a second state. When the driving telescopic assembly 200 is in the first state, the part of the driving telescopic assembly 200 connected to the body 100 moves in a direction away from the water hole 101, so that the driving telescopic assembly 200 is separated from the body 100 and is always connected to the filter element assembly 300, so as to pull the filter element assembly 300 and the driving telescopic assembly 200 out of the body 100; or, when the driving telescopic assembly 200 is in the second state, the part of the driving telescopic assembly 200 connected to the body 100 moves in a direction close to the water hole 101, so that the driving telescopic assembly 200 is connected to both the body 100 and the filter element assembly 300.

[0048] That is, during the process of switching the drive telescopic assembly from the second state to the first state, the drive telescopic assembly 200 can be configured such that the portion connected to the body 100 moves in a direction away from the water passage 101, so that the drive telescopic assembly 200 is separated from the body 100 and remains connected to the filter element assembly 300, so that the filter element assembly 300 and the drive telescopic assembly 200 can be simultaneously withdrawn from the body 100. Alternatively, during the process of switching the drive telescopic assembly 200 from the first state to the second state, the drive telescopic assembly 200 can be configured such that the portion connected to the body 100 moves in a direction close to the water passage 101, so that the drive telescopic assembly 200 is connected to both the body 100 and the filter element assembly 300.

[0049] In an embodiment of the present application, a drive telescopic assembly 200 is provided in the water purification device, and the drive telescopic assembly 200 is provided with a water passage 201 that cooperates with the water hole 101 and the water channel 301. In this way, after the drive telescopic assembly 200 is connected to the body 100 and the filter element assembly 300, it can not only realize the water flow function but also realize the limit connection of the filter element assembly 300. When the filter element assembly 300 needs to be removed, the part of the drive telescopic assembly 200 connected to the body 100 moves in a direction away from the water hole 101 of the body 100, so that the drive telescopic assembly 200 is separated from the body 100 and remains connected to the filter element assembly 300. In this way, the operator can hold the drive telescopic assembly 200 to pull the filter element assembly 300 out of the body 100, thereby realizing the disassembly of the filter element assembly 300, which is convenient to operate and has high maintenance and installation efficiency.

[0050] In summary, the embodiment of the present application provides a water purification device, which may include: a body, a drive telescopic assembly and a filter element assembly. By arranging the drive telescopic assembly in the water purification device, the drive telescopic assembly is provided with a water passage that cooperates with the water hole and the waterway. In this way, after the drive telescopic assembly is connected to the body and the filter element assembly, it can not only realize the water flow function but also realize the limiting connection of the filter element assembly. When the filter element assembly needs to be disassembled, the part of the drive telescopic assembly connected to the body moves in the direction away from the water hole of the body, so that the drive telescopic assembly is separated from the body and is always connected to the filter element assembly. In this way, the operator can hold the drive telescopic assembly to pull the filter element assembly out of the body, thereby realizing the disassembly of the filter element assembly, which is convenient to operate and has high maintenance and installation efficiency.

[0051] For example, Figure 2As shown, the filter element assembly 300 may include: a filter element cover 310 and a filter element body 320 connected to each other. The filter element cover 310 may be provided with a water channel 301. For example, the number of the water channels 301 may be multiple, the number of the water holes 101 in the body 100 may be multiple, and the number of the water channels 201 in the telescopic drive assembly 200 may be multiple. The multiple water channels 301, the multiple water holes 101, and the multiple water channels 201 may correspond one to one.

[0052] Optional, please refer to Figure 4 and Figure 5 , Figure 4 This is a partial structural diagram of a water purification device provided in an embodiment of the present application. Figure 5 It is a partial structural diagram of another water purification device provided in an embodiment of the present application. The portion of the body 100 in which the water hole 101 is provided, the drive telescopic component 200 and the filter element component 300 are arranged in sequence along the first direction f, and the portion of the drive telescopic component 200 can be slidably connected to the body 100 and the filter element component 300 along the first direction f. Among them, the portion of the drive telescopic component 200 slides in a direction away from the water hole 101 in the body 100, so that the drive telescopic component 200 is separated from the body 100 and is always connected to the filter element component 300. For example, by arranging the portion of the body 100 in which the water hole 101 is provided, the drive telescopic component 200 and the filter element component 300 along the first direction f, the portion of the drive telescopic component 200 can be slidably connected to the body 100 and the filter element component 300 along the first direction f. In this way, by driving the telescopic assembly 200 to move along the first direction f, separation and connection with the body 100 can be achieved, and then the filter element assembly 300 can be disassembled and installed with the body 100.

[0053] In this application, if Figure 5 As shown, the body 100 may have a mounting groove 102, the filter element assembly 300 may be slidably connected to the mounting groove 102, and the movement direction of the filter element assembly 300 relative to the body 100 may intersect with the first direction f. Here, when the filter element assembly 300 is assembled with the body 100, after the filter element assembly 300 is placed in the mounting groove 102, the telescopic assembly 200 is driven to slide to achieve connection with both the body 100 and the filter element assembly 300, thereby completing the installation of the filter element assembly 300. When disassembling the filter element assembly 300, after the telescopic assembly 200 is driven to separate from the body 100, the telescopic assembly 200 is controlled to pull the filter element assembly 300 out of the mounting groove 102. For example, the movement direction of the filter element assembly 300 relative to the body 100 may be perpendicular to the first direction f.

[0054] In the examples of this application, please refer to Figure 6 and Figure 7 , Figure 6This is a partial structural exploded diagram of a water purification device provided in an embodiment of the present application. Figure 7 This is a partial exploded schematic diagram of another water purification device provided by an embodiment of the present application. The telescopic drive assembly 200 may include a drive member 210 and a telescopic waterway member 220. The telescopic waterway member 220 may be provided with a water passage 201 and slidably connected to both the filter element assembly 300 and the housing 100. In one conceivable embodiment, the drive member 210 may be in transmission connection with both the telescopic waterway member 220 and the filter element assembly 300.

[0055] The driving member 210 may be configured to drive the water channel telescopic member 220 to slide during movement.

[0056] In this case, the water channel expansion member 220 is provided in sliding connection with both the filter element assembly 300 and the housing 100, and the driving member 210 is in transmission connection with the water channel expansion member 220 and the filter element assembly 300. In this way, by controlling the movement of the driving member 210, the water channel expansion member 220 is driven to slide relative to the housing 100 and the filter element assembly 300. After the water channel expansion member 220 slides to separate from the housing 100, the filter element assembly 300 is extracted from the housing 100 by the driving member 210. That is, in the case where the housing 100 is provided with the mounting groove 102, the driving member 210 can extract the filter element assembly 300 from the mounting groove 102.

[0057] It should be noted that, in other possible implementations, the driving member 210 may also be only in transmission connection with the water channel telescopic member 220 to drive the water channel telescopic member 220 to slide.

[0058] Alternatively, in one achievable embodiment, the two ends of the water channel expansion member 220 may correspond to the water hole 101 in the housing 100 and the water channel 301 in the filter element assembly 300, respectively. One end of the water channel expansion member 220 is slidably connected to the water hole 101, and / or the other end of the water channel expansion member 220 is slidably connected to the water channel 301. In this way, the water channel 301 in the filter element assembly 300 and the water hole 101 in the housing 100 cooperate with the water channel expansion member 220, achieving both a water flow function and a position-limiting connection for the water channel expansion member 220, resulting in a simple, reliable, and practical structure.

[0059] For example, the two ends of the water channel expansion member 220 can be sealed and slidably connected to the water hole 101 in the body 100 and the water channel 301 in the filter element assembly 300, respectively. For example, an annular sealing groove M is provided at the end of the water channel expansion member 220. The annular sealing groove M can be used to set an annular seal to abut against the inner sidewall of the water hole 101 and the inner sidewall of the water channel 301 and enable sliding relative to each other.

[0060] In another achievable embodiment, the two ends of the water channel 201 in the water channel expansion member 220 can correspond to the portion of the filter element assembly 300 where the water channel 301 is provided and the portion of the body 100 where the water hole 101 is provided, respectively. The portion of the body 100 where the water hole 101 is provided can be slidably connected to one end of the water channel 201, and / or the portion of the filter element assembly 300 where the water channel 301 is provided can be slidably connected to the other end of the water channel 201. In this way, the portion of the filter element assembly 300 where the water channel 301 is provided and the portion of the body 100 where the water hole 101 is provided cooperate with the water channel 201, achieving both a water flow function and a position-limiting connection for the water channel expansion member 220, resulting in a simple, reliable, and practical structure.

[0061] In the embodiments of this application, Figure 7 As shown, in one possible case, the driving member 210 may be provided with a movable connection end H, which can be rotatably connected to the outer side of the water channel telescopic member 220 and swingably connected to the side of the filter element assembly 300. The driving member 210 can be configured to drive the end of the water channel telescopic member 220 connected to the body 100 to extend and retract during the swinging process relative to the filter element assembly 300. In this case, by controlling the driving member 210 to swing relative to the filter element assembly 300, the end of the water channel telescopic member 220 connected to the body 100 can be driven to extend and retract, and after the water channel telescopic member 220 is separated from the body 100, the filter element assembly 300 is pulled out by the driving member 210.

[0062] For example, Figure 7 As shown, the movable connection end H of the driving member 210 may have a sliding arc groove C1 on the side facing the filter element assembly 300. The top edge of the filter element assembly 300 has a positioning pin C2, which can be located in the sliding arc groove C1 and slidably engage with the sliding arc groove C1. The virtual center of the sliding arc groove C1 is eccentrically arranged with respect to the rotation axis of the movable connection end H and the water channel expansion member 220.

[0063] In this application, if Figure 7 、 Figure 8 and Figure 9 As shown, Figure 8 yes Figure 7 The schematic diagram of the retraction of the water channel telescopic member in the water purification equipment is shown. Figure 9 yes Figure 7 A schematic diagram of the extension of the water channel member in the water purification device is shown. One of the movable connection end H and the side surface of the water channel extension member 220 may have a rotation axis Z1, and the other of the movable connection end H and the side surface of the water channel extension member 220 may have a rotation hole Z2 rotatably connected to the rotation axis Z1.

[0064] For examples, please refer to Figure 10 and Figure 11 , Figure 10 yes Figure 8 A top view of the retracted water channel telescopic member in the water purification device is shown.

[0065] In another possible situation, Figure 6 As shown, one end of the driving member 210 can be rotatably connected to the side of the filter element assembly 300, and the driving member 210 is swingably connected to the water channel telescopic member 220. The driving member 210 is configured to drive the end of the water channel telescopic member 220 connected to the body 100 to extend and retract during its rotation relative to the filter element assembly 300. In this case, by controlling the driving member 210 to rotate relative to the filter element assembly 300, the end of the water channel telescopic member 220 connected to the body 100 can be driven to extend and retract, and after the water channel telescopic member 220 is separated from the body 100, the filter element assembly 300 can be withdrawn via the driving member 210.

[0066] For example, Figure 6 As shown, the driving member 210 may include a swing arm 211 having a rotation hole K1 at one end; the top edge portion of the filter element assembly 300 includes a rotation axis K2 rotatably connected to the rotation hole K1. The side of the swing arm 211 facing the water channel telescopic member 220 includes a sliding groove C3 distributed along the extension direction of the swing arm 211, and the outer side surface of the water channel telescopic member 220 includes a positioning axis Z3 that slidably engages with the sliding groove C3. In this case, during the rotation of the swing arm 211 relative to the filter element assembly 300, the sliding drive of the water channel telescopic member 220 is achieved through the cooperation between the sliding groove C3 and the positioning axis Z3.

[0067] For example, Figure 6 As shown, the driving member 210 may include a handle portion 212 and two oppositely disposed swing arms 211, wherein the handle portion 212 may be fixedly connected to the other ends of the two swing arms 211. In this way, the operator may hold the handle portion 212 to drive the driving member 210, which is convenient to operate.
