[0038] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] In one embodiment, a handle 12 is provided, comprising a support rod and a cantilever, wherein the support rod is used to be rotatably connected to the filter element assembly 11, and the cantilever is connected to the support rod and suspended on one side of the support rod. Figure 1 As shown, the end of the cantilever away from the support rod is a locking portion 122. When the support rod rotates forward relative to the filter element assembly 11, the locking portion 122 can press against the waterway plate 132, so that the connector 112 on the filter element assembly 11 is inserted into and pressed against the interface 1324 on the waterway plate 132. The cantilever is provided with a reinforcing rib 127.

[0040] The above solution provides a handle 12 for assembling the filter element assembly 11 and the waterway plate 132. Specifically, Figure 2 and Figure 4 As shown, during assembly, when the support rod rotates relative to the filter element assembly 11, the locking portion 122 presses against the waterway plate 132, providing force for the filter element assembly 11 to insert the connector 112 into the interface 1324. Because the cantilever is suspended outside the support rod, it is prone to breakage during assembly and rotation of the handle 12. To address this, a reinforcing rib 127 is further provided on the cantilever to increase its strength, thereby enhancing the strength of the handle 12 to meet the requirements for disassembly of the filter element assembly 11.

[0041] Further, if Figure 1 As shown, in one embodiment, the cantilever further includes a main body portion 124, and the main body portion 124 connects the locking portion 122 and the support rod. A gripping portion 1211 is provided on the support rod for applying force to grip the support rod so that the support rod rotates forward. The locking portion 122 is bent relative to the main body portion 124 in a direction away from the gripping portion 1211, forming an inwardly concave arc surface on the cantilever. The surface on the locking portion 122 used to form the arc surface is a first pressing surface 1221, which is used to press against the waterway plate 132. Therefore, when the waterway plate 132 presses against the first pressing surface 1221, there will be greater stress at the connection between the locking portion 122 and the main body portion 124. Therefore, as Figure 1As shown, the reinforcing ribs 127 are provided at the corner where the locking portion 122 and the main body portion 124 are connected, and the reinforcing ribs 127 are distributed along the stress direction to increase the strength of the cantilever and prevent the cantilever from breaking.

[0042] Specifically, in one embodiment, the portion of the waterway plate 132 used to press against the locking portion 122 is a limiting portion 1321 .

[0043] In order to further improve the strength of the connection between the locking portion 122 and the main body portion 124, in one embodiment, Figure 1 As shown, the thickness of the corner where the locking portion 122 is connected to the main body portion 124 is greater than the thickness of other portions of the locking portion 122 .

[0044] More specifically, Figure 1 As shown, in one embodiment, the support rod includes a middle gripping section 121, and the gripping portion 1211 is located on the middle gripping section 121. Both ends of the middle gripping section 121 are provided with a transition point and the cantilever for rotational connection with the filter element assembly 11. The two cantilevers are arranged opposite each other, and the side of each cantilever opposite the other cantilever is provided with a thickened protrusion. The thickened protrusion is located at the corner where the locking portion 122 connects to the main body 124, and the thickened protrusion is distributed along the edge of the cantilever.

[0045] The thickened protrusion makes the thickness of the corner where the locking portion 122 and the main body portion 124 are connected greater than the thickness of other parts of the locking portion 122, thereby improving the overall force-bearing strength of the handle 12.

[0046] Furthermore, in one embodiment, Figure 1 As shown, the first pressing surface 1221 is tilted relative to the plane where the support rod is located, and the distance between the first pressing surface 1221 and the plane where the support rod is located gradually decreases in the direction away from the main body 124.

[0047] Therefore, when the first pressing surface 1221 presses against the limiting portion 1321, Figure 4 and Figure 5 As shown, the first pressing surface 1221 can provide a force for the limiting portion 1321 to move closer to the support rod, ensuring that the limiting portion 1321 and the locking portion 122 are matched together.

[0048] Furthermore, in one embodiment, Figure 1As shown, the handle 12 also includes a disassembly portion 123 connected to the support rod. When the support rod is reversed relative to the filter element assembly 11, the disassembly portion 123 can be pressed against the waterway plate 132 to pull the connector 112 out of the interface 1324.

[0049] The gripping portion 1211 , the transition point and the locking portion 122 on the handle 12 constitute a first labor-saving lever, and the gripping portion 1211 , the transition point and the disassembly portion 123 on the handle 12 constitute a second labor-saving lever, making the handle 12 more labor-saving when used.

[0050] Specifically, in one embodiment, the disassembly portion 123 is a part of the support rod. Figure 1 As shown, the disassembly portion 123 is connected to the main body 124, and the disassembly portion 123 and the locking portion 122 are arranged relative to each other, and the disassembly portion 123, the locking portion 122 and the main body 124 form a clearance groove 125. Figure 2 、 Figure 4 and Figure 5 As shown, when the support rod rotates forward, the limiting portion 1321 gradually enters the making way slot 125 from the opening of the making way slot 125 until the locking portion 122 presses against the limiting portion 1321 so that the connector 112 is inserted into and pressed against the interface 1324. Figure 6 and Figure 7 As shown, when the handle 12 is reversed, the limiting portion 1321 gradually withdraws from the opening of the clearance groove 125 , and the disassembly portion 123 gradually presses against the limiting portion 1321 until the connector 112 is pulled out of the interface 1324 .

[0051] like Figure 4 and Figure 5 As shown, when the limiting portion 1321 is located in the clearance groove 125 , the disassembly portion 123 and the locking portion 122 are respectively located at the upper and lower sides of the limiting portion 1321 .

[0052] Specifically, if Figure 1 As shown, the openings of the clearance groove 125 are located at the end surfaces of both ends of the handle 12 , and the clearance groove 125 passes through the inner and outer sides of the handle 12 , so that the locking portion 122 and the disassembly portion 123 are arranged at intervals.

[0053] Furthermore, in one embodiment, the position on the support rod for rotationally connecting with the filter element assembly 11 is a transition point, such as Figure 1As shown, the transition point is located on the disassembly portion 123. The surface of the locking portion 122 that presses against the limiting portion 1321 is located on the side of the transition point away from the gripping portion 1211, and the surface of the disassembly portion 123 that presses against the limiting portion 1321 is located on the side of the transition point away from the gripping portion 1211. This ensures that the power arm length of the first and second effort-saving levers is greater than the resistance arm length.

[0054] Further, if Figures 2 to 7 As shown, in one embodiment, a water purifier 10 is provided, comprising a waterway plate 132, a filter element assembly 11 and the above-mentioned handle 12. Figure 7 As shown, the filter element assembly 11 is provided with a connector 112. Figure 8 and Figure 9 As shown, the waterway plate 132 is provided with an interface 1324 that matches the connector 112. The waterway plate 132 is provided with a limiting portion 1321 for pressing against the locking portion 122, and the support rod is rotatably connected to the filter element assembly 11.

[0055] During assembly, the connector 112 is aligned with the interface 1324, and the handle 12 is then rotated forward so that the locking portion 122 can press against the stop portion 1321 on the waterway plate 132, allowing the connector 112 to be inserted and pressed into the interface 1324 on the waterway plate 132. Because the cantilever is suspended from one side of the support rod and resistance is generated between the connector 112 and the interface 1324 when inserted, the cantilever is subjected to high stress and is prone to breakage. Therefore, reinforcing ribs 127 are further provided on the cantilever to increase the strength of the cantilever and the handle 12, thereby ensuring that the filter element assembly 11 and the waterway plate 132 can be properly assembled.

[0056] The first effort-saving lever and the second effort-saving lever reduce the force required during operation, thereby improving the convenience of operation.

[0057] Specifically, during the assembly process, Figure 2 and Figure 4 As shown, after a downward force is applied to the gripping portion 1211, with the aid of the first force-saving lever, the limiting portion 1321 provides support for the locking portion 122, and the handle 12 rotates with the point on the locking portion 122 that is pressed against the limiting portion 1321 as a fulcrum. The transfer point moves relative to the waterway plate 132, and synchronously drives the filter element assembly 11 connected to the handle 12 to move relative to the waterway plate 132, so that the connector 112 is inserted into the interface 1324.

[0058] like Figure 4 and Figure 5The figure shows the state when the connector 112 is installed in the interface 1324, at which time the limiting portion 1321 is pressed against the locking portion 122. Figure 6 and Figure 7 As shown, the gripping portion 1211 of the handle 12 applies an upward force, and with the help of the second force-saving lever, the disassembly portion 123 gradually presses against the limiting portion 1321. During the reversal of the handle 12, the limiting portion 1321 provides support for the disassembly portion 123, allowing the handle 12 to rotate around the point on the disassembly portion 123 that presses against the limiting portion 1321. The transfer point moves relative to the waterway plate 132, synchronously driving the filter element assembly 11 to move relative to the waterway plate 132, allowing the connector 112 to be removed from the interface 1324.

[0059] Furthermore, in order to ensure the sealing reliability when the connector 112 is connected to the interface 1324, in one embodiment, Figure 8 As shown, the connector 112 is provided with a sealing ring. When the connector 112 is inserted into the interface 1324 , the sealing ring is pressed between the connector 112 and the side wall of the interface 1324 .

[0060] The sealing ring will hinder the relative movement between the connector 112 and the interface 1324, thus making the disassembly and assembly process more laborious.

[0061] Further, if Figure 8 As shown, in one embodiment, the end of the filter element assembly 11 provided with the connector 112 is the head end, and the position on the filter element assembly 11 for rotationally connecting with the support rod is the support point, which is located at the head end of the filter element assembly 11. The connector 112 is suspended outside the head end of the filter element assembly 11, and the outlet of the connector 112 is axially directed toward the tail end of the filter element assembly 11. Figure 9 and Figure 10 As shown, the interface 1324 is located on the top surface of the waterway plate 132, and the limiting portion 1321 is located at the top of the waterway plate 132. The direction of plugging and unplugging the connector 112 is the axial direction of the filter element assembly 11.

[0062] like Figure 2 and Figure 4 As shown, during the assembly process, the locking portion 122 gradually presses against the side of the limiting portion 1321 close to the rear end of the filter element assembly 11, so that the connector 112 is tightly inserted into the interface 1324. Figure 6 and Figure 7As shown, during the disassembly process, the disassembly portion 123 presses against the side of the limiting portion 1321 away from the rear end of the filter element assembly 11 .

[0063] More specifically, Figure 9 and Figure 10 As shown, in one embodiment, two auxiliary plates 1325 are provided on the waterway plate 132, the front of the waterway plate 132 faces the filter element assembly 11, and the auxiliary plates 1325 extend to the front of the waterway plate 132. The two auxiliary plates 1325 are respectively located on the left and right sides of the waterway plate 132, and the limiting portion 1321 includes a protrusion located on the side of the auxiliary plate 1325 facing away from the filter element assembly 11.

[0064] During the disassembly process, the disassembly portion 123 and the locking portion 122 are mainly located on the side of the auxiliary plate 1325 away from the filter element assembly 11. During the rotation of the handle 12, the positions of the disassembly portion 123 and the locking portion 122 and the limiting portion 1321 change, thereby achieving disassembly.

[0065] Further, if Figure 4 As shown, in one embodiment, the surface of the limiting portion 1321 that presses against the locking portion 122 is a first mating surface 1322 , and the first mating surface 1322 gradually extends toward the top surface of the waterway plate 132 in the direction close to the waterway plate 132 .

[0066] When the locking portion 122 presses against the first mating surface 1322 to lock the filter element assembly 11, Figure 4 and Figure 5 As shown, the force provided by the first mating surface 1322 to the locking portion 122 can be decomposed into a first component force F1 along the axial direction of the filter element assembly 11 and a second component force F2 perpendicular to the waterway plate 132. In other words, the limiting portion 1321 not only provides the first component force F1 for the handle 12 and the filter element assembly 11 to insert the connector 112 tightly into the interface 1324, but also provides the second component force F2 for the handle 12 and the filter element assembly 11 to press against the waterway plate 132, ensuring that the handle 12 is reliably locked with the limiting portion 1321.

[0067] Specifically, when the locking portion 122 and the first mating surface 1322 are completely pressed together, Figure 5 As shown, the first pressing surface 1221 is in contact with the first matching surface 1322 .

[0068] Specifically, if Figure 4 and Figure 5As shown, the direction of the second component force F2 is substantially distributed along the opening direction of the clearance groove 125 , so that the locking portion 122 can prevent the limiting portion 1321 from exiting the clearance groove 125 .

[0069] Further, if Figure 9 and Figure 10 As shown, in one embodiment, the surface of the limiting portion 1321 that presses against the disassembly portion 123 is the second mating surface 1323. Figure 4 As shown, when the connector 112 is inserted and pressed into the interface 1324, the disassembly portion 123 and the second mating surface 1323 are spaced apart. In other words, at the initial stage of the handle 12 reversal, the disassembly portion 123 and the second mating surface 1323 are not in contact, and there is a certain gap between them. The limit portion 1321 will not hinder the reversal of the handle 12. When the handle 12 is rotated by a preset angle, as shown in FIG. Figure 6 As shown, the disassembly portion 123 contacts the second mating surface 1323 , and then the transition point begins to move relative to the waterway plate 132 , thereby improving the operational feel.

[0070] Specifically, in order to further improve the operating feel and avoid the situation where the resistance is large or small, such as Figures 4 to 7 As shown, the surface of the disassembly portion 123 that presses against the second mating surface 1323 is an arc-shaped convex surface. Therefore, in the process of reversing the handle 12, the length of the resistance arm of the second effort-saving lever gradually increases. When the disassembly portion 123 begins to press against the second mating surface 1323, the joint 112 and the interface 1324 just begin to move relative to each other, the required force is large, and the ratio of the power arm to the resistance arm is large, so the effort-saving ratio is large. As the handle 12 continues to reverse, the tightness of the squeeze between the joint 112 and the interface 1324 decreases, the required force decreases, and the ratio of the power arm to the resistance arm is small, and the effort-saving ratio becomes smaller. Therefore, the force required by the user to act on the handle 12 changes less during the entire process, thereby improving the operating feel.

[0071] Furthermore, in one embodiment, Figure 2 As shown, the water purifier 10 further includes a support shell 131, which encloses a mounting cavity into which the filter element assembly 11 is inserted. The orientation of the mounting cavity is consistent with the orientation of the interface 1324. The waterway plate 132 is connected to the support shell 131 to form the entire housing assembly 13.

[0072] Specifically, during the assembly process, Figure 2As shown, the filter element assembly 11 is first preliminarily inserted into the installation cavity, the connector 112 is aligned with the interface 1324, and then the handle 12 is rotated forward, the locking portion 122 is pressed against the limit portion 1321, and the transfer point on the handle 12 moves relative to the waterway plate 132, and the waterway plate 132 is connected to the support shell 131, so that the transfer point also moves relative to the support shell 131 at the same time, and then the connector 112 is locked in the interface 1324 while the filter element assembly 11 is installed and locked in the installation cavity.

[0073] Similarly, during the reversal of the handle 12 , the connector 112 is pulled out from the interface 1324 , and the filter element assembly 11 is pulled out from the installation cavity by a certain distance, so that the filter element assembly 11 is loosened relative to the waterway plate 132 and the support shell 131 .

[0074] Specifically, in one embodiment, when the handle 12 is rotated forward, the distance that the transition point can move in the direction away from the bottom wall of the installation cavity is not less than the distance that the connector 112 is pulled out from the interface 1324; when the handle 12 is reversed, the distance that the transition point can move in the direction close to the bottom wall of the installation cavity is not less than the distance that the connector 112 is inserted into the interface 1324.

[0075] Furthermore, the outer circumferential surface of the support shell 131 is provided with a limiting rib, which is located on the side of the auxiliary plate 1325 close to the bottom wall of the installation cavity. Therefore, when the disassembly portion 123 presses against the surface of the limiting portion 1321 facing away from the bottom wall of the installation cavity, the limiting portion 1321 and the auxiliary plate 1325 will not move toward the bottom wall of the installation cavity, thereby providing a reaction force for the disassembly portion 123, thereby removing the filter element assembly 11 from the installation cavity and simultaneously loosening the connector 112 from the interface 1324.

[0076] Furthermore, in one embodiment, one of the support member and the filter element assembly 11 is provided with a rotating shaft 126, and the other is provided with a slot 111. Figure 1 As shown, the support member is provided with a rotating shaft 126. Figure 11 and Figure 12 As shown, the filter element assembly 11 is provided with a slot 111. The rotating shaft 126 is inserted into the slot 111. The sidewall of the slot 111 is provided with a recess 1111. The rotating shaft 126 is provided with a rotation-stopping protrusion 1261. The rotation-stopping protrusion 1261 is located in the recess 1111 and is used to limit the rotation angle of the handle 12 relative to the filter element assembly 11. Specifically in this embodiment, the transfer point is located at the location of the rotating shaft 126, and the support point is located at the location of the slot 111.

[0077] During use, the handle 12 can only rotate within a certain range allowed, and the disassembly process between the connector 112 and the interface 1324 can be realized within this allowable rotation range, further improving the convenience of operation. Figure 11 and Figure 12 As shown, during the disassembly process, when the handle 12 is reversed to the extreme position, the anti-rotation protrusion 1261 contacts the wall of the recess 1111 and cannot continue to rotate in the reverse direction. At this time, the handle 12 is roughly in a state of being axially distributed along the installation cavity, and the limiting protrusion has withdrawn from the clearance groove 125, which is convenient for the user to act on the middle grip section 121 to pull out the filter element assembly 11.

[0078] Furthermore, in one embodiment, Figures 2 to 8 As shown, the filter element assembly 11 is provided with an outer shell cover 14. When the filter element assembly 11 is installed in the installation cavity, the outer shell cover 14 covers the opening of the installation cavity.

[0079] Further, if Figure 13 As shown, the end of the filter element assembly 11 is provided with a snap assembly 15 with elastic reset capability. Figure 1 As shown, the middle grip section 121 is provided with a bayonet 1212 that matches the snap assembly 15. Figure 4 As shown, when the locking portion 122 presses against the limiting portion 1321 so that the connector 112 is inserted into and pressed into the interface 1324 , the snap assembly 15 can be locked in cooperation with the bayonet 1212 .

[0080] After the snap assembly 15 is locked with the bayonet 1212, the handle 12 cannot rotate relative to the filter element assembly 11, so that the locking portion 122 on the handle 12 is always pressed against the limiting portion 1321, ensuring that the connector 112 is always inserted tightly into the interface 1324.

[0081] Specifically, in one embodiment, Figures 2 to 8 As shown, the handle 12 is provided at the head end of the filter element assembly 11 , the outer shell cover 14 is provided on the end surface of the head end of the filter element assembly 11 , and the outer shell cover 14 covers the snap assembly 15 on the filter element assembly 11 .

[0082] like Figure 13 As shown, in one embodiment, when the connector 112 is tightly inserted into the interface 1324, the middle gripping section 121 of the handle 12 rotates to a position that fits against the end of the filter element assembly 11. The snap assembly 15 is located on the inner side of the middle gripping section 121, and the bayonet 1212 is located on the inner side of the middle gripping section 121 facing the snap assembly 15.

[0083] Furthermore, in one embodiment, Figure 13 As shown, the filter element assembly 11 is provided with a button 16, and the pressing direction of the button 16 is along the axial direction of the interface 1324. Figure 14 As shown, the button 16 and the snap assembly 15 contact each other through an inclined surface, converting the pressing movement of the button 16 into the radial movement of the snap assembly 15 along the interface 1324, so that the snap assembly 15 escapes from the bayonet 1212.

[0084] When the connector 112 needs to be extracted from the interface 1324 , the button 16 is pressed, and the snap assembly 15 moves radially along the interface 1324 to exit the bayonet 1212 , and then the handle 12 is reversed to remove the filter element assembly 11 .

[0085] Specifically, if Figure 14 As shown, the snap assembly 15 is provided with a first inclined surface 1511. The first inclined surface 1511 is arranged obliquely relative to the cross-section of the interface 1324, and the normal direction of the first inclined surface 1511 faces the bayonet 1212. The button 16 is located on the side of the first inclined surface 1511 facing the bayonet 1212. When the button 16 is pressed, the button 16 applies a force to the first inclined surface 1511 in the opposite direction of the interface 1324, thereby causing the snap assembly 15 to move out of the bayonet 1212.

[0086] The outer shell cover 14 is provided with a first perforation and a second perforation. When the outer shell cover 14 is covered on the filter element assembly 11, the button 16 can be exposed outside the outer shell cover 14 through the first perforation, so that the user can press the button 16, and the snap assembly 15 can be inserted into the bayonet 1212 through the second perforation.

[0087] Furthermore, in one embodiment, Figure 14 As shown, the snap assembly 15 includes a first slider 151 and an elastic return member 152. The first slider 151 is slidably disposed relative to the filter element assembly 11, and its sliding direction is parallel to the cross-section of the filter element assembly 11. The elastic return member 152 is located between the first slider 151 and the filter element assembly 11 and is used to provide a return force for the first slider 151 to slide toward the bayonet 1212. Specifically, the elastic return member 152 can be a compression spring, the axis of which is parallel to the cross-section of the filter element assembly 11.

[0088] Furthermore, in another embodiment, Figure 15As shown, a slide buckle 17 is provided at the end of the filter element assembly 11, and a socket matching the slide buckle 17 is provided on the middle grip section 121. When the locking portion 122 is pressed against the limiting portion 1321 so that the connector 112 is inserted and pressed into the interface 1324, the slide buckle 17 can be slidably inserted into the socket.

[0089] When the handle 12 is rotated forward until the connector 112 is inserted into the interface 1324, the socket is opposite to the slider 17. The slider 17 is manually pushed so that the slider 17 is inserted into the socket, so that the handle 12 cannot rotate relative to the filter element assembly 11, so that the connector 112 can be reliably fitted in the interface 1324.

[0090] Furthermore, in one embodiment, one of the slide 17 and the middle grip 1211 is provided with a buckle 171, and the other is provided with a mating piece that cooperates with the buckle 171. When the slide 17 is inserted into the socket, the buckle 171 is connected to the mating piece buckle 171.

[0091] Specifically, if Figure 16 As shown, the slider 17 is provided with a latch 171. A mating member is provided on the intermediate grip portion 1211. When the slider 17 is manually pushed and inserted into the receptacle, the latch 171 engages with the mating member. Without actively releasing the latch 171 from the mating member, the slider 17 cannot be removed from the receptacle, and the handle 12 cannot rotate relative to the filter element assembly 11.
