DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] The technical solution of the present disclosure will be further described by the embodiments with reference to the drawings as follows. It can be understood that the embodiments described herein are only for illustrating the present disclosure, and are not intended to limit the present disclosure.

[0009] In one embodiment of the present application, a sifter is provided as shown in Figs. 1 to 8. The sifter has a function of adjustable length. The sifter includes an upper sifter body 10 and a lower sifter body 20. The upper sifter body 10 is provided with an inlet 101 for waste to flow in. In actual use, the inlet 101 may be connected to a waste discharge port provided in the toilet body, and waste enters the waste discharge flow path 30 of the sifter through the inlet 101 and is discharged through an outlet 201 provided in the lower sifter body 20. The upper sifter body 10 and the lower sifter body 20 may be connected to each other by a sliding connection structure 40, and are surrounded together to create the waste discharge flow path 30. The length of the waste discharge flow path 30 can be adjusted by adjusting the sliding connection structure 40. The upper body 10 of the shifter and the lower body 20 of the shifter are fitted together in a sliding manner to obtain a waste discharge passage 30 whose length is adjustable, so that the length of the shifter can be adjusted, and the adjustment operation feel is relatively good.

[0010] In some exemplary embodiments, as shown in Fig. 4 and Fig. 5, the sliding connection structure 40 includes a sliding rail 401 and a sliding slot 402 which cooperate with each other. The sliding rail 401 may be installed on the shifter upper body 10, and the sliding slot 402 may be installed on the shifter lower body 20. Or, the sliding rail 401 is installed on the shifter lower body 20, and the sliding slot 402 is installed on the shifter upper body 10. In the embodiments of the present application, the sliding rail 401 is installed on the shifter upper body 10, and the sliding slot 402 is installed on the shifter lower body 20 as an example to describe the technical solution. The sliding slot 402 may be integrally molded with the shifter lower body 20, and the integral molding process is, for example, an injection molding process.

[0011] In some exemplary embodiments, as shown in Figures 4 and 5, the sliding rail 401 and the sliding slot 402 may be installed outside the waste discharge passage 30, in which case both the sliding rail 401 and the sliding slot 402 are easily installed, blind installation is avoided, and the sliding connection structure 40 can be prevented from occupying the space inside the waste discharge passage 30 so as not to affect the waste discharge function of the shifter.

[0012] In some exemplary embodiments, as shown in FIG. 4, one end of the sliding rail 401 is provided with a connection hole 403, which is used to mount the sliding rail 401, and the mounting can be performed using a fastening member, such as a screw, so as to realize a detachable assembly between the sliding rail 401 and the shifter upper body 10. A plurality of connection holes 403 can be provided, so as to ensure the robustness of the mounting of the sliding rail 401. As shown in FIG. 4, the shifter upper body 10 can be provided with a position limiting slot 102, so that the sliding rail 401 can be accurately mounted on the shifter upper body 10. The other end of the sliding rail 401 can be fitted into the sliding slot 402, and can slide back and forth along the extension direction of the sliding slot 402, that is, it can slide back and forth along the left and right direction shown in FIG. 1. In the actual process of assembling the shifter, the sliding rail 401 and the sliding slot 402 are first assembled, and then the sliding rail 401 assembled with the sliding slot 402 is detachably fixed to the shifter upper body 10. By installing in this manner, the difficulty of assembling the shifter upper body 10 and the shifter lower body 20 can be reduced.

[0013] In some exemplary embodiments, as shown in Fig. 4, a connecting post 103 is installed on the outer wall of the shifter upper body 10. The connecting post 103 and the connecting hole 403 may be installed in a pair, and the connecting post 103 is used to connect with a fastening member, thereby realizing a detachable assembly between the sliding rail 401 and the shifter upper body 10. By utilizing the design structure of the connecting post 103, the adverse effect on the waste discharge channel 30 caused by the installation operation of the sliding rail 401 and the shifter upper body 10 can be avoided, so that the waste discharge channel 30 can have a high sealing ability.

[0014] In some exemplary embodiments, as shown in Figures 4 and 5, one end of the sliding rail 401 where the connecting hole 403 is provided is referred to as a fixed end, and one end of the sliding rail 401 that slides and fits into the sliding slot 402 is referred to as a free end. The fixed end of the sliding rail 401 is fixed to the shifter upper body 10.

[0015] A first position limiting protrusion 404 is provided in the sliding slot 402, and a second position limiting protrusion 405 is provided on the portion of the sliding rail 401 located in the sliding slot 402. As shown in Fig. 6, the first position limiting protrusion 404 is provided to abut against the second position limiting protrusion 405, thereby restricting the sliding rail 401 from leaving the sliding slot 402 along the extending direction of the sliding slot 402, and restricting the position of the shifter upper body 10 to the shifter lower body 20, thereby preventing the two from being separated. By providing the first position limiting protrusion 404 in the sliding slot 402 and the second position limiting protrusion 405 in the sliding rail 401, the design layout of the entire shifter is more compact, and the outer size of the shifter is reduced. The first position limiting protrusion 404 may be arranged in a U-shaped slot as shown in Fig. 4, and the opening of the U-shaped slot may face the shifter upper body 10 side, and the second position limiting protrusion 405 may be arranged in an elongated shape as shown in Fig. 4. As shown in Fig. 6, the first position limiting protrusion 404 and the second position limiting protrusion 405 cooperate with each other, and the second position limiting protrusion 405 contacts the surface of the first position limiting protrusion 404 that is away from the shifter upper body 10 along the extension direction of the sliding slot 402, thereby realizing the position limit of both the shifter upper body 10 and the shifter lower body 20 along the longitudinal direction of the waste discharge passage 30.

[0016] 5, an avoidance gap 406 is left between the first position limiting protrusion 404 and the side wall of the sliding slot 402. The size of the avoidance gap 406 is denoted as L1, and by utilizing the avoidance gap 406, the sliding rail 401 can be positioned in the sliding slot 402 in the radial direction (the radial direction is the horizontal direction perpendicular to the extension direction of the sliding slot 402) and can slide and adjust through the avoidance gap 406 without being affected by the first position limiting protrusion 404, thereby realizing a smooth installation of the sliding rail 401.

[0017] In some exemplary embodiments, as shown in Fig. 4, the sliding rail 401 is provided with an avoidance slot 407, which may be extended along the length adjustment direction of the shifter. In the shifter product, the first position limiting protrusion 404 is located in the avoidance slot 407, and one end of the avoidance slot 407 that is away from the fixed end is closed to form the second position limiting protrusion 405. The sliding slot 402 and the first position limiting protrusion 404 may be integrally molded by injection molding or the like. The sliding rail 401 and the second position limiting protrusion 405 may be integrally molded, which reduces the assembly process and improves the installation efficiency.

[0018] 5, in some exemplary embodiments, the abutment position between the first position limiting protrusion 404 and the second position limiting protrusion 405 has a gap between one end of the sliding slot 402 close to the fixed end of the sliding rail 401, the gap is denoted as L2, and the L2 is used to define the minimum insertion length between the shifter upper body 10 and the shifter lower body 20, which is convenient for the installation of the sealing structure 50, and thus ensures that the waste discharge channel 30 obtains a relatively good sealing property. The sealing structure 50 may include a sealing strip, etc.

[0019] In some exemplary embodiments, as shown in Fig. 4 and Fig. 5, one end of the sliding slot 402 away from the fixed end of the sliding rail 401 may be set to be open, so that the sliding rail 401 can be inserted into the sliding slot 402 along the extension direction of the sliding slot 402 (the left-right direction shown in Fig. 1). As shown in Fig. 4, the sliding slot 402 is further provided with a third position limiting protrusion 408. The third position limiting protrusion 408 extends along the up-down direction of the shifter, and the third position limiting protrusion 408 is used to abut against the sliding rail 401, thereby restricting the sliding rail 401 from leaving the sliding slot 402 along a direction perpendicular to the extension direction of the sliding slot 402. The third position limiting protrusion 408 may be integrally formed with the sliding slot 402.

[0020] In some exemplary embodiments, as shown in Figures 4 and 5, a plurality of sliding protrusions 409 are installed along the longitudinal direction of the sliding rail 401, and the sliding protrusions 409 protrude along the up-down direction. In the structure of the shifter, the sliding protrusions 409 and the slot walls of the sliding slots 402 contact and fit together along the up-down direction, thereby reducing the contact area between the sliding rail 401 and the sliding slots 402. The use of the installed sliding protrusions 409 is advantageous in avoiding large-area contact between the sliding rail 401 and the sliding slots 402, reducing the sliding resistance between the shifter upper body 10 and the shifter lower body 20, and improving the smoothness of sliding between them.

[0021] In some exemplary embodiments, as shown in Figures 1 and 2, the shifter upper body 10 includes a first flow passage portion 104 and an inlet portion 105. The first flow passage portion 104 and the inlet portion 105 may be integrally molded. The inlet 101 is disposed in the inlet portion 105. As shown in Figure 4, the first flow passage portion 104 is provided with a first flow passage 301 communicating with the inlet 101.

[0022] As shown in FIG. 1 and FIG. 2, the shifter lower body 20 includes a second flow passage portion 202 and an outlet portion 203. As shown in FIG. 4, the outlet 201 is installed in the outlet portion 203, and the second flow passage portion 202 is installed with a second flow passage 302 communicating with the outlet 201. The inlet 101 and the outlet 201 may be configured in a circular shape. The first flow passage portion 104 and the second flow passage portion 202 are inserted and fitted together, so that the second flow passage 302 and the first flow passage 301 are surrounded together to create a waste discharge flow passage 30. The first flow passage portion 104 may be inserted into the second flow passage portion 202 along the direction of waste discharge, so that the waste is prevented from flowing into the insertion gap between the two, leakage is prevented, and the sealing reliability of the insertion area between the two can be improved. A seal structure 50 may be installed in the area where the first flow passage portion 104 is inserted into the second flow passage portion 202.

[0023] 4 to 8, in some exemplary embodiments, the seal structure 50 may include at least one seal ring 501. The seal ring 501 may be made of urethane foam, rubber, or the like. The seal ring 501 may be bonded to the first flow path portion 104 or the second flow path portion 202, and the seal ring 501 may be formed in an annular shape surrounding the first flow path portion 104 or the second flow path portion 202.

[0024] 4, a plurality of position limiting ribs 502 may be provided on one of the outer walls of the first flow path portion 104 and the second flow path portion 202 located on the inside of the insertion. The position limiting rib 502 is provided in an annular shape along the circumferential direction of the first flow path portion 104 or the circumferential direction of the second flow path portion 202. A seal groove is formed between two adjacent position limiting ribs 502 along the longitudinal direction of the waste discharge flow path 30. A seal ring 501 may be fitted in the seal groove. The seal ring 501 may be fitted in the seal groove by a method such as adhesion or crimping, thereby realizing the fixing of the seal ring 501.

[0025] In the embodiment of the present application, the technical solution is described by taking the insertion of the first flow passage portion 104 into the second flow passage portion 202 as an example, and the installation of the position limiting rib 502 on the outer wall of the first flow passage portion 104 as an example. As shown in FIG. 4, the outer wall of the first flow passage portion 104 is further provided with a plurality of support ribs 503 that are installed at intervals along the circumferential direction. One end of the support rib 503 is connected to the position limiting rib 502 and extends along the insertion direction of the first flow passage portion 104 and the second flow passage portion 202. The side of the support rib 503 that is away from the outer wall of the first flow passage portion 104 contacts the inner wall of the second flow passage portion 202. The contact area between the first flow passage portion 104 and the second flow passage portion 202 is reduced by the installation of the plurality of support ribs 503, and thus the sliding resistance between the first flow passage portion 104 and the second flow passage portion 202 is reduced, and the smoothness of the sliding is improved. The multiple support ribs 503 can also play a role of support and guide, thereby facilitating the sliding adjustment of both the shifter upper body 10 and the shifter lower body 20 .

[0026] 5, the insertion end of the first flow passage portion 104 may be installed at an incline, and the top of the insertion end of the first flow passage portion 104 is farther from the inlet 101 than the bottom. The insertion end of the second flow passage portion 202 may be installed at an incline, and is parallel to the insertion end of the first flow passage portion 104. Both the insertion end of the first flow passage portion 104 and the insertion end of the second flow passage portion 202 are installed at an incline, which makes it easier to insert the shifter upper body 10 and the shifter lower body 20 into each other, and improves the assembly efficiency of the entire shifter.

[0027] In some exemplary embodiments, as shown in Fig. 5, the shifter upper body 10 further includes a support portion 106. The support portion 106 is located below the inlet 101 and is connected to the first flow passage portion 104 and the inlet portion 105. The support portion 106 is installed to abut against the ground, thereby increasing the supportability of the entire shifter and enhancing the stability of the support. As shown in Fig. 5, the support portion 106 may be installed to be an arc-shaped plate, the inlet portion 105 may be a ring extending downward, and the support portion 106 may be installed coaxially with the central axis of the inlet portion 105.

[0028] In some exemplary embodiments, as shown in FIG. 4, a first seal 504 is provided at the inlet 101, and a second seal 505 is provided at the outlet 201. The first seal 504 may be designed to be the same as the second seal 505, thereby reducing the number of parts, avoiding mis-installation of the two seals, and improving the efficiency of the assembly process. The first seal 504 may be provided as a rubber ring, which is fitted around the inlet 101 of the inlet part 105. The first seal 504 and the second seal 505 are provided at the two connection areas at the top and bottom of the shifter, respectively, thereby ensuring the sealing of the connection points of the shifter and improving the use performance of the shifter.

[0029] In some exemplary embodiments, as shown in FIG. 2, at least one of the upper shifter body 10 and the lower shifter body 20 is provided with a mark 60 for indicating the use length of the shifter. For example, the mark 60 may be provided at the outlet 203. In the present embodiment, the shifter is provided with two use lengths. FIGS. 7 and 8 are cross-sectional schematic views of the shifter at two use lengths, and the use length of the shifter may be set to more according to the actual situation. The format of the mark 60 may be set as shown in FIG. 2. The mark 60 indicates multiple use lengths of the shifter, which can indicate to the user that the shifter has an adjustable function and facilitate the user to select a suitable shifter length.

[0030] In another embodiment of the present application, a toilet is provided. The toilet comprises a toilet body and a sifter according to any of the above embodiments, and an inlet 101 communicates with a waste discharge outlet installed in the toilet body. Since the toilet comprises the sifter according to any of the above embodiments, it has all the beneficial effects described above, and will not be described again here.
