[0036] In the description of the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "connection," "direct connection," "indirect connection," "fixed connection," "installation," and "assembly" should be understood in a broad sense. For example, they may refer to a fixed connection, a detachable connection, or an integral connection. The terms "installation," "connection," and "fixed connection" may refer to a direct connection, an indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0037] like Figures 1 to 6 As shown, an embodiment of the present invention provides a shifter having an adjustable length function. The shifter includes a shifter upper body 10 and a shifter lower body 20. The shifter upper body 10 is provided with an inlet 101 for sewage to flow in. In actual use, the inlet 101 is connected to the sewage outlet on the toilet body, and the sewage enters the sewage channel 30 of the shifter through the inlet 101 and is discharged through the outlet 201 provided on the shifter lower body 20. The shifter lower body 20 and the shifter upper body 10 can be plugged in and matched to jointly enclose a sewage channel 30 with adjustable length. As Figures 2 to 4 As shown, the shifter may further include a limiting structure 50. The limiting structure 50 may limit the adjustment of the length of the sewage discharge channel 30, thereby ensuring the reliability of the length adjustment of the shifter.

[0038] In some exemplary embodiments, the limiting structure 50 may include a limiting spring piece 501 and a limiting protrusion 502, one of which is provided on the upper body 10 of the shifter, and the other is provided on the lower body 20 of the shifter. The limiting spring piece 501 and the limiting protrusion 502 abut against each other to limit the disengagement of the upper body 10 of the shifter and the lower body 20 of the shifter. During the plugging process of the upper body 10 of the shifter and the lower body 20 of the shifter, the limiting spring piece 501 is squeezed by the limiting protrusion 502 and deformed toward the outside of the sewage channel 30. After the limiting spring piece 501 passes the limiting protrusion 502, the limiting spring piece 501 returns to its original state under the action of its own elastic force. After the assembly of the upper body 10 of the shifter and the lower body 20 of the shifter is completed, as shown in FIG. Figure 4 As shown, the limiting protrusion 502 can prevent the upper body 10 of the shifter from escaping from the lower body 20 of the shifter along the length direction of the sewage discharge channel 30, that is, Figure 4 The limiting spring piece 501 and the limiting protrusion 502 cooperate with each other to limit the upper body 10 of the shifter to the lower body 20 of the shifter, thereby preventing the two from being separated.

[0039] In some exemplary embodiments, the limiting spring piece 501 and the limiting protrusion 502 are located on the outside of the sewage channel 30, which can avoid the limiting structure from occupying the sewage channel, avoid blind installation, improve assembly efficiency, and avoid dirt from contaminating the limiting spring piece and the limiting protrusion, so as not to affect the reliability of the limiting fit between the limiting spring piece and the limiting protrusion.

[0040] In some exemplary embodiments, the shifter may further include a sliding connection structure 40. The upper shifter body 10 and the lower shifter body 20 are slidably connected via the sliding connection structure 40, and together enclose a wastewater discharge channel 30. Adjusting the sliding connection structure 40 allows the length of the wastewater discharge channel 30 to be adjusted. The sliding fit between the upper shifter body 10 and the lower shifter body 20 creates a length-adjustable wastewater discharge channel 30, achieving both adjustable shifter length and a comfortable adjustment feel.

[0041] like Figures 2 to 4As shown, the sliding connection structure 40 may include a matching slide rail 401 and a slide groove 402. The slide rail 401 may be arranged on the upper body 10 of the shifter, and the slide groove 402 may be arranged on the lower body 20 of the shifter. Alternatively, the slide rail 401 may be arranged on the lower body 20 of the shifter, and the slide groove 402 may be arranged on the upper body 10 of the shifter. In an embodiment of the present utility model, the technical solution is described by taking the example of setting the slide rail 401 on the upper body 10 of the shifter and the slide groove 402 on the lower body 20 of the shifter. The slide groove 402 may be integrally formed with the lower body 20 of the shifter, for example, by using an injection molding process. Designing the slide groove and the lower body of the shifter to be an integrally formed structure can simplify the assembly process of the shifter and improve the assembly efficiency of the shifter.

[0042] In some exemplary embodiments, Figure 3 、 Figure 3A As shown, one of the limiting spring piece 501 and the limiting protrusion 502 can be provided on the slide rail 401, and the other can be provided on the slide groove 402. For example, the limiting spring piece 501 can be provided at the end of the slide rail 401 away from the inlet 101. For example, the limiting spring piece 501 can be formed integrally with the slide rail 401. The limiting spring piece 501 can include a first end 501b and a second end 501c connected to each other, and the second end 501c is located between the first end 501b and the inlet 101. The first end 501b can be connected to the slide rail 401, and the second end 501c can be a free end. During the plugging process of the shifter upper body 10 and the shifter lower body 20, the second end 501c is squeezed by the limiting protrusion 502 and deformed toward the outside of the sewage discharge channel 30. After the second end 501c passes through the limiting protrusion 502, the second end 501c returns to its original state under the action of its own elastic force.

[0043] like Figure 3 、 Figure 3B As shown, the limiting protrusion 502 can be provided on the chute 402. For example, the limiting protrusion 502 can be integrally formed with the chute 402. The limiting protrusion 502 can be provided at the end of the chute 402 away from the outlet 201. Integrating the limiting structure and the sliding connection structure can make the shifter design more compact, achieve a concealed limiting structure, and enhance the aesthetics of the appearance. Placing the limiting spring on the slide rail and the limiting protrusion on the chute can reduce mold complexity and manufacturing costs.

[0044] like Figure 3As shown, during the assembly of the shifter, the slide rail 401 together with the limiting spring piece 501 is installed on the upper body 10 of the shifter to assemble into the upper body assembly of the shifter, and the slide groove 402 together with the limiting protrusion 502 is integrally formed with the lower body 20 of the shifter to form the lower body assembly of the shifter. During the plug-in process of the upper body assembly of the shifter and the lower body assembly of the shifter, the limiting spring piece 501 is squeezed by the limiting protrusion 502 and deformed toward the outside of the sewage channel 30. After the limiting spring piece 501 passes the limiting protrusion 502, the limiting spring piece 501 returns to its original state under the action of its own elastic force. After the assembly of the upper body assembly of the shifter and the lower body assembly of the shifter is completed, as shown in FIG. Figure 4 As shown, the limiting protrusion 502 can prevent the slide rail 401 from escaping from the slide groove 402 along the direction in which the slide groove 402 extends. Figure 4 The limiting spring piece 501 and the limiting protrusion 502 cooperate with each other to limit the upper body 10 of the shifter to the lower body 20 of the shifter, thereby preventing the two from being separated.

[0045] In some exemplary embodiments, Figure 2 、 Figure 3 As shown, the limiting protrusion 502 can be in the form of a U-shaped groove, the opening of the U-shaped groove can be facing one side of the shifter upper body 10, and the limiting protrusion 502 has a first limiting surface 502a, which can be a raised arc surface and located at the bottom of the U-shaped groove. The limiting spring 501 can be in the form of a rectangular block, and the limiting spring 501 has a second limiting surface 501a, which is located at the second end 501c and can be a concave arc surface. The second limiting surface 501a and the first limiting surface 502a are in contact with each other, so that the limiting spring 501 and the limiting protrusion 502 are in abutting contact. The second limiting surface 501a and the first limiting surface 502a are both arc surfaces, which can increase the matching area of ​​the first limiting surface and the second limiting surface without increasing the external dimensions of the limiting protrusion and the limiting spring, thereby ensuring the reliability of the limiting.

[0046] In some exemplary embodiments, after the upper shifter body 10 and the lower shifter body 20 are assembled in place, the upper shifter body 10 and the lower shifter body 20 are plugged into each other. Figure 2 、 Figure 3As shown, the shifter may have an insertion port 20a, and the first limiting surface 502a is located on the side of the limiting protrusion 502 away from the insertion port 20a, and there is a minimum spacing L between the first limiting surface 502a and the insertion port 20a along the length direction of the sewage discharge channel 30, and the minimum spacing L is greater than zero. For example, the insertion port 20a and the first limiting surface 502a may be located together on the lower body 20 of the shifter. Alternatively, the insertion port 20a and the first limiting surface 502a may be located together on the upper body 10 of the shifter. The minimum spacing L can be used to define the minimum connection length between the upper body of the shifter and the lower body of the shifter, and it can be convenient to set a sealing structure at the position where the upper body of the shifter and the lower body of the shifter are connected, so as to ensure that the sewage discharge channel obtains better sealing. For example, the sealing structure can be a sealing strip, etc. The limiting protrusion 502 is designed to be a U-shaped groove, and the first limiting surface 502a is designed at the bottom of the U-shaped groove, which can not only ensure the minimum spacing L, but also make the limiting protrusion 502 have a higher structural strength. Furthermore, during the assembly process, the limiting spring piece 501 will only undergo elastic deformation when it passes through the bottom of the U-shaped groove. This can shorten the time that the limiting spring piece 501 is in the elastic deformation state during the assembly process, extend the service life of the limiting spring piece 501, and ensure the reliability of the limiting spring piece 501.

[0047] In some exemplary embodiments, Figures 2 to 4 As shown, the limiting structure 50 may further include a limiting stop bar 503, which may be disposed on the side of the chute 402 away from the sewage discharge channel 30. For example, the limiting stop bar 503 may be integrally formed with the chute 402. The limiting stop bar 503 extends in the vertical direction of the shifter and is used to abut against the slide rail 401 to limit the slide rail 401 from escaping from the chute 402 in a direction perpendicular to the extension of the chute 402.

[0048] In some exemplary embodiments, Figures 2 to 4 As shown, the slide rail 401 and the slide groove 402 are arranged on the outside of the sewage channel 30. This arrangement can facilitate installation and avoid blind installation on the one hand, and on the other hand, it can avoid the sliding connection structure 40 occupying the space in the sewage channel 30, so as not to affect the sewage discharge performance of the shifter.

[0049] In some exemplary embodiments, Figure 2 As shown, a connecting hole 403 is provided at one end of the slide rail 401. The connecting hole 403 is used to install the slide rail 401. Fasteners, such as screws, can be used for installation to achieve detachable assembly of the slide rail 401 and the upper body 10 of the shifter. Multiple connecting holes 403 can be provided to ensure the firmness of the installation of the slide rail 401. The other end of the slide rail 401 can be embedded in the slide groove 402, and the slide rail 401 can slide back and forth along the extension direction of the slide groove 402, that is, Figure 2The left and right directions are shown. A mounting groove 102 can be provided on the upper body 10 of the shifter, and the mounting groove 102 can be located below the inlet 101. A connecting column 103 can be provided in the mounting groove 102, and the connecting column 103 is provided in a group with the connecting hole 403. The connecting column 103 is used to connect the fasteners, and can realize the detachable assembly of the slide rail 401 and the upper body 10 of the shifter. The design structure of the connecting column 103 can avoid the adverse effects of the installation operation on the sewage flow channel 30, and can make the sewage flow channel 30 have a higher sealing performance. Figure 2 、 Figure 3 As shown, the end of the slide rail 401 provided with the connecting hole 403 can be recorded as the fixed end, and the end of the slide rail 401 slidingly embedded in the slide groove 402 can be recorded as the free end. The fixed end of the slide rail 401 is fixed to the upper body 10 of the shifter.

[0050] In some exemplary embodiments, Figure 2 As shown, the slide rail 401 can be provided with a plurality of sliding protrusions 404. The plurality of sliding protrusions 404 can be located on the side surfaces of the slide rail 401 in the vertical direction. The plurality of sliding protrusions 404 can be spaced apart along the sliding direction of the slide rail 401. For example, the slide rail 401 and the plurality of sliding protrusions 404 can be integrally formed. The sliding protrusions 404 contact and cooperate with the groove walls of the slide groove 402, thereby reducing the contact area between the slide rail 401 and the slide groove 402 and improving the sliding operation performance of the sliding connection structure.

[0051] In some exemplary embodiments, Figure 2 As shown, the upper body 10 of the shifter may include a first flow channel portion 104 and an inlet portion 105. The first flow channel portion 104 and the inlet portion 105 may be integrally formed. The inlet 101 is arranged on the inlet portion 105. A first flow channel 301 connected to the inlet 101 is provided on the first flow channel portion 104. The lower body 20 of the shifter may include a second flow channel portion 202 and an outlet portion 203. The outlet 201 is arranged on the outlet portion 203, and the second flow channel portion 202 is provided with a second flow channel 302 connected to the outlet 201. The inlet 101 and the outlet 201 may be arranged in a circular shape. The first flow channel portion 104 and the second flow channel portion 202 are plugged into each other so that the second flow channel 302 and the first flow channel 301 together enclose a sewage flow channel 30. Along the direction of sewage discharge, the first flow channel portion 104 can be inserted into the second flow channel portion 202, which can prevent sewage from flowing into the plug-in gap between the two to avoid leakage, and can improve the sealing reliability of the plug-in area between the two. A sealing structure may be provided in a region where the first flow channel portion 104 is inserted into the second flow channel portion 202 .

[0052] In some exemplary embodiments, Figure 3As shown, the upper body 10 of the shifter may further include a support portion 106. The support portion 106 is located below the inlet 101 and is connected to the first flow channel portion 104 and the inlet portion 105. The support portion 106 is configured to abut against the ground, which can increase the overall support of the shifter and improve the stability of the support. Figure 2 As shown, the support portion 106 can be configured as an arc-shaped plate, the inlet portion 105 can be configured as a circular ring extending downward, and the support portion 106 can be coaxially arranged with the central axis of the inlet portion 105 .

[0053] In some exemplary embodiments, Figure 2 、 Figure 5 、 Figure 6 As shown, the displacer may further include a sealing structure 60, which may include at least one sealing ring 601. The sealing ring 601 may be made of polyurethane foam or rubber. The sealing ring 601 may be bonded to the first flow channel portion 104 or the second flow channel portion 202 and may be formed in an annular shape.

[0054] A plurality of limiting ribs 504 can be provided on the outer wall of one of the first flow channel portion 104 and the second flow channel portion 202 that is located on the inner side of the plug-in connection. The limiting ribs 504 are arranged in a ring shape along the circumference of the first flow channel portion 104 or the circumference of the second flow channel portion 202. A sealing groove is formed between two adjacent limiting ribs 504 along the length direction of the sewage discharge channel 30. The sealing ring 601 can be embedded in the sealing groove and can be bonded or crimped to achieve the fixation of the sealing ring 601. In the embodiment of the present utility model, the technical solution is explained by taking the example of inserting the first flow channel portion 104 into the second flow channel portion 202 and the example of setting the limiting ribs 504 on the outer wall of the first flow channel portion 104. The outer wall of the first flow channel portion 104 can also be provided with a plurality of support ribs 505 arranged at intervals along the circumference. One end of the support rib 505 is connected to the limiting rib 504 and extends along the plug-in connection direction of the first flow channel portion 104 and the second flow channel portion 202. The side of the support rib 505, away from the outer wall of the first flow channel portion 104, contacts the inner wall of the second flow channel portion 202. The provision of multiple support ribs 505 reduces the contact area between the first flow channel portion 104 and the second flow channel portion 202, thereby lowering the sliding resistance between the first flow channel portion 104 and the second flow channel portion 202 and improving the smoothness of sliding. Furthermore, the multiple support ribs 505 also provide support and guidance, facilitating the sliding adjustment of the shifter upper body 10 and the shifter lower body 20.

[0055] like Figure 5As shown, the sealing ring 601 may include a base 601a and at least one lip 601b. The base 601a may be annular, and the at least one lip 601b may be disposed outside the annular shape. For example, the sealing ring 601 may include a base 601a and two lips 601b. The two lips 601b may be spaced apart along the central axis of the base 601a. ​​In practical applications, the sealing ring's moisture and high temperature resistance may be improved by increasing the radial dimension of the lip along the base, that is, the lip's height.

[0056] In some exemplary embodiments, Figure 5 、 Figure 6 As shown, the sealing structure 60 may further include a first seal 611 and a second seal 612. The first seal 611 may be provided at the inlet 101, and the second seal 612 may be provided at the outlet 201. The first seal 611 and the second seal 612 may be identical, which may reduce the number of parts, avoid misassembly of the two seals, and improve assembly efficiency. The first seal 611 may be provided as a rubber ring, and sleeved around the inlet 101 on the inlet portion 105, and the second seal 612 may be provided as a rubber ring, and sleeved around the outlet 201 on the outlet portion 203. The first seal and the second seal are respectively provided in the upper and lower connecting areas of the shifter, which may ensure the sealing of the connection of the shifter and improve the performance of the shifter.

[0057] During the assembly of the shifter, Figure 3 As shown, they can be assembled into the upper body assembly of the shifter and the lower body assembly of the shifter respectively. The upper body assembly of the shifter includes the upper body 10 of the shifter, the slide rail 401, the limiting spring piece 501, the sealing ring 601 and the first sealing member 611, etc. The lower body assembly of the shifter includes the lower body 20 of the shifter, the slide groove 402, the limiting protrusion 502 and the second sealing member 612, etc. Then, the slide rail 401 and the slide groove 402 are plugged in and slidably matched to realize the assembly of the upper body assembly of the shifter and the lower body assembly of the shifter, thereby completing the assembly of the entire shifter.

[0058] In some exemplary embodiments, Figure 2 As shown, one of the upper body 10 and the lower body 20 of the shifter can be provided with a mark 70 for marking the length of the shifter. Figure 2 As shown, the mark 70 can be set on the outlet portion 203. In the embodiment of the present utility model, the shifter is provided with two use lengths as an example. Figure 5 、 Figure 6 The following are cross-sectional views of the shifter at two different lengths. The lengths of the shifter can be varied according to the actual situation. Figure 2By using the provided mark, the various lengths of the shifter can be identified, which can remind the user that the shifter has an adjustable function and can also facilitate the user to select a suitable length of the shifter.

[0059] In another embodiment of the present invention, a toilet is provided. The toilet includes a toilet body and the shifter described in any of the above embodiments. The inlet 101 is connected to a sewage outlet provided on the toilet body. The toilet including the shifter described in any of the above embodiments has all the aforementioned beneficial effects, which will not be further elaborated here.
