[0045] The present utility model will be further described below in conjunction with embodiments and the accompanying drawings.

[0046] Example 1 of the water receiving tray 2:

[0047] As Figures 1 - 3 and Figures 21 - 23 and Figure 26 shown, a water receiving tray applicable to a toilet is used to collect urine during urination or flushing water during buttock flushing or toilet flushing, and guide the collected liquid to a urine collection box or a sewage box.

[0048] The water receiving tray 2 mainly includes a water receiving tray bottom plate 21 and a water receiving tray side baffle 22 extending upward from the circumferential outer edge of the water receiving tray bottom plate 21, that is: the water receiving tray bottom plate 21 and the water receiving tray side baffle 22 together form a disk-shaped structure with an open upper part, which is used to collect urine during urination or flushing water during buttock flushing or toilet flushing.

[0049] In this embodiment, a water receiving tray sealing ring 31 in a circular ring structure is provided on the water receiving tray side baffle 22. By setting the water receiving tray sealing ring 31 in a circular ring structure on the water receiving tray side baffle 22 in this embodiment, it can effectively play the role of preventing water splash and water surging, avoid the problem of excessive humidity in the biodegradable container, and ensure the stability of the aerobic reaction of the culture medium.

[0050] Specifically, the water receiving tray sealing ring 31 has a first radially sealing band 311 extending radially along the bottom plate 21 of the water receiving tray. The first radially sealing band 311 is a circular thin plate structure. When the water receiving tray 2 is located directly below the excretion channel 111 of the toilet bowl 11 of the toilet main body 1, the first radially sealing band 311 can seal the circumferential gap between the excretion channel 111 and the water receiving tray 2.

[0051] The water receiving tray sealing ring 31 of this embodiment is entirely composed of the first radially sealing band 311. Any position on the bottom surface of the water receiving tray sealing ring 31 can be fixedly connected to the upper edge of the side baffle 22 of the water receiving tray. In this embodiment, the outer edge of the first radially sealing band 311 is fixedly connected to the upper edge of the side baffle 22 of the water receiving tray.

[0052] Furthermore, the material of the water receiving tray sealing ring 31 can be common elastic sealing materials such as silica gel, rubber, polyurethane, or polytetrafluoroethylene. The water receiving tray sealing ring 31 is fixedly connected to the side baffle 22 of the water receiving tray by bonding. It can also be: the water receiving tray sealing ring 31 made of elastic plastic material and the water receiving tray 2 made of rigid plastic material are integrally formed by two-color injection molding process, so that the connection strength between the two is higher and more durable.

[0053] In this embodiment, a liquid drainage structure 23 communicating with it is provided on the side baffle 22 and / or the bottom plate 21 of the water receiving tray, that is: the liquid drainage structure 23 is provided on the side baffle 22 or the bottom plate 21 of the water receiving tray, or the liquid drainage structure 23 is located on both the bottom plate 21 and the side baffle 22 of the water receiving tray at the same time. The liquid drainage structure 23 is used to guide the collected liquid to the urine collection box or the sewage box.

[0054] The liquid drainage structure 23 preferably adopts a liquid drainage pipe in a tubular structure. Compared with the upper-open diversion groove in the Chinese utility model patent with the publication number CN219527847U, it is not easy to have water leakage situations such as water surging due to excessive flow rate, thus further improving the overall anti-leakage performance of the toilet water receiving tray.

[0055] Among them, the inlet of the liquid drainage pipe is a liquid drainage port 223 opened on the side baffle 22 of the water receiving tray. The bottom of the liquid drainage port 223 is lower than or flush with the top surface of the bottom plate 21 of the water receiving tray. And, the bottom of the liquid drainage port 223 is lower than or flush with the top surface of the bottom plate 21 of the water receiving tray, so as to better drain the liquid collected in the water receiving tray 2 and avoid the situation of the water receiving tray 2 emitting an odor due to the inability to completely drain the liquid.

[0056] In this embodiment, the side baffle 22 of the water receiving tray can be perpendicular to the bottom plate 21 of the water receiving tray, or the side baffle 22 of the water receiving tray can be inclined inward from top to bottom, so that the water receiving tray 2 has a larger volume.

[0057] In this embodiment, the water receiving tray connecting seat 244 on the side baffle 22 and / or the bottom plate 21 of the water receiving tray, that is, the water receiving tray connecting seat 244 is provided on the side baffle 22 or the bottom plate 21 of the water receiving tray, or the water receiving tray connecting seat 244 is simultaneously located on the bottom plate 21 and the side baffle 22 of the water receiving tray. The water receiving tray connecting seat 244 is used to connect with the water receiving tray operating mechanism 24, and the water receiving tray operating mechanism 24 is used to control the rotation of the water receiving tray 2.

[0058] Specifically, the water receiving tray operating mechanism 24 includes a lever 241, a rotating shaft 242, and a linkage assembly 243. The rotating shaft 242 is vertically installed on the toilet main body 1 in a rotatable manner. The upper end of the rotating shaft 242 passes through the toilet main body 1 upward and is synchronously rotated with the lever 241 installed thereon. The lower end of the rotating shaft 242 is located inside the toilet main body 1 and is connected to the water receiving tray connecting seat 244 through the linkage assembly 243. Thus, by rotating the lever 241, the bottom plate 21 and the side baffle 22 of the water receiving tray can be moved back and forth between the first position and the second position.

[0059] The linkage assembly 243 in this embodiment has two implementation manners:

[0060] Embodiment 1 of the connection assembly 243: Please refer to Figure 18 and Figure 19 , the connection assembly 243 includes a connecting rod 234a and a hinge member 243b. A connecting member mounting plate 12 is provided in the toilet main body 1, and an arc-shaped chute 13 adapted to the hinge member 243b is formed on the connecting member mounting plate 12. The hinge member 243b is slidably installed in the arc-shaped chute 13. The connecting rod 234a is arranged in the horizontal direction. One end of the connecting rod 234a is synchronously rotated and sleeved on the lower end of the rotating shaft 242. The water receiving tray connecting seat 244 of the water receiving tray 2 is hingedly installed at the other end of the connecting rod 234a through the hinge member 243b. Therefore, through the structural design of the arc-shaped chute 13, when the operator rotates the lever 241 back and forth in the horizontal direction, the water receiving tray 2 can be rotated back and forth between the first position directly below the excretion passage 111 of the toilet main body 1 and the second position outside the excretion passage 111.

[0061] Embodiment 2 of the connection assembly 243: Please refer to Figure 20, the connecting component 243 includes a connecting rod 234a and a sliding fit rod 243b'. A connecting piece mounting plate 12 is also provided in the toilet main body 1. A fitting chute 13' that slidably fits with the sliding fit rod 243b' is installed on the connecting piece mounting plate 12. One end of the fitting chute 13' near the water receiving tray 2 penetrates through the connecting piece mounting plate 12. At the same time, a linear chute 243a1 extending along its length direction is provided on the connecting rod 234a. The lower end of the water receiving tray connecting seat 244 of the water receiving tray 2 is hinged with a circular slider 243c. The circular slider 243c can not only slide along the linear chute 243a1 but also rotate in the linear chute 243a1. At the same time, one end of the sliding fit rod 243b' is slidably inserted into the fitting chute 13', and the other end is hinged with the water receiving tray connecting seat 244 of the water receiving tray 2.

[0062] When the operator rotates the lever 241 back and forth in the horizontal direction, the water receiving tray 2 can be rotated back and forth between a first position directly below the excretion passage 111 of the toilet bowl 11 and a second position outside the excretion passage 111.

[0063] Whether it is Embodiment 1 of the connecting component 243 or Embodiment 2 of the connecting component 243, the lower end of the rotating shaft 242 is preferably rotatably connected to the mounting plate 12, which improves the reliability of the installation of the rotating shaft 242.

[0064] Please refer to Figure 23 , the lower end surface of the excretion passage 111 can be directly in frictional fit or interference fit with the top surface of the first radial sealing band 311.

[0065] A channel sealing ring 32 in a circular ring structure can also be sleeved on the lower end of the excretion passage 111. The channel sealing ring 32 has the following two embodiments:

[0066] Embodiment 1 of the channel sealing ring 32: Please refer to Figure 22 , the bottom surface of the channel sealing ring 32 is a flat structure. When the water receiving tray 2 is directly below the excretion passage 111, the bottom surface of the channel sealing ring 32 is in frictional fit or interference fit with the top surface of the first radial sealing band 311. By providing the channel sealing ring 32, when the water receiving tray 2 is in the first position directly below the excretion passage 111, the channel sealing ring 32 cooperates with the first radial sealing band 311, and can effectively seal the circumferential gap between the top of the water receiving tray 2 and the bottom of the excretion passage 111, ensuring that the liquid falling from the excretion passage 111 can be reliably collected by the water receiving tray 2, thereby achieving a better effect of preventing splashing and surging of water.

[0067] Embodiment 2 of the channel sealing ring 32: Please refer to Figure 21, the channel sealing ring 32 includes a sealing ring mounting sleeve 321 sleeved on the lower end of the discharge channel 111. A circular water retaining thin sheet 322 is integrally formed at the bottom of the sealing ring mounting sleeve 321. The circular water retaining thin sheet 322 extends downward. When the water receiving tray 2 is directly below the discharge channel 111, the lower edge of the circular water retaining thin sheet 322 is in frictional fit with the top surface of the first radial sealing band 311.

[0068] Therefore, by providing the circular water retaining thin sheet 322 with a thin sheet structure at the bottom of the channel sealing ring 32 and using the frictional fit between the lower edge of the circular water retaining thin sheet 322 and the top surface of the first radial sealing band 311, it is possible to effectively seal the circumferential gap between the top of the water receiving tray 2 and the bottom of the discharge channel 111, and at the same time reduce the interference effect, that is, the frictional force, generated by the channel sealing ring 32 on the rotation of the toilet water receiving tray, thereby ensuring the smooth rotation of the water receiving tray 2.

[0069] It should be noted that one or more circles of circular water retaining thin sheets 322 can be provided at the bottom of the sealing ring mounting sleeve 321. When multiple circles of circular water retaining thin sheets 322 are provided, the diameters of the circular water retaining thin sheets 322 gradually increase, which can ensure excellent sealing effect and avoid water leakage problems. When only one circle of circular water retaining thin sheet 322 is provided, the lower edge of the circular water retaining thin sheet 322 is close to the inner edge of the first radial sealing band 311. Usually, the lower edge of the circular water retaining thin sheet 322 is 2 mm - 3 mm away from the inner edge of the first radial sealing band 311, which not only ensures the sealing performance and avoids gaps due to improper rotation, but also avoids the problem of the top of the first radial sealing band 311 emitting an odor due to water accumulation.

[0070] Furthermore, the thickness of the lower part of the circular water retaining thin sheet 322 gradually decreases from top to bottom, so that it can not only achieve a good sealing effect, but also minimize the friction with the first radial sealing band 311, making the rotation of the toilet water receiving tray smoother.

[0071] In addition, a support flange 323 adapted to the discharge channel 111 is protruded on the inner wall of the sealing ring mounting sleeve 321. The lower end of the discharge channel 111 is supported on the support flange 323, which not only plays a role in positioning the installation of the channel sealing ring 32, but also can avoid the problem that the channel sealing ring 32 cannot achieve a good sealing effect due to upward movement after long-term use.

The water receiving tray sealing ring 31 is installed on the side baffle 22 of the water receiving tray through the first positioning structure 313, thereby further improving the reliability of the installation of the water receiving tray sealing ring 31 on the water receiving tray 2 and extending the service life.

[0074] The first positioning structure 313 in this embodiment is a positioning ring extending axially along the bottom plate 21 of the water receiving tray. The first positioning structure 313 and the first radial sealing band 311 together make the cross-section of the water receiving tray sealing ring 31 an "L" - shaped structure.

The annular rib is also either installed in the positioning groove 221 by a snap - fit method or installed in the positioning groove 221 by common methods such as bonding and fixing.

[0093] Embodiment 12 of the water receiving tray 2:

[0094] Please refer to Figure 14 , Figure 24 and Figure 25 , the main structure of the water receiving tray 2 in this embodiment is exactly the same as that of the water receiving tray 2 in Embodiment 1. The difference lies in that: the structure of the water receiving tray sealing ring 31 is different. The water receiving tray sealing ring 31 includes a first positioning structure 313 and a first axial sealing rib 312 arranged on the top of the first positioning structure 313. The first axial sealing rib 312 is a ring extending axially away from the bottom plate 21 of the water receiving tray along the bottom plate 21 of the water receiving tray. In this embodiment, the first positioning structure 313 is a circular thin plate structure extending radially along the bottom plate 21 of the water receiving tray. The first axial sealing rib 312 is located in the middle of the top surface of the first positioning structure 313. The first positioning structure 313 and the first axial sealing rib 312 together make the cross - section of the water receiving tray sealing ring 31 an inverted "T" - shaped structure.

[0095] It should be noted that multiple first axial sealing ribs 312 extending axially away from the bottom plate 21 of the water receiving tray can also be coaxially arranged on the top of the first positioning structure 313. At the same time, the diameters of the first axial sealing ribs 312 are different from each other.

[0096] Please refer to Figure 24, the lower end surface of the drainage channel 111 can directly frictionally cooperate with the upper edge of the first axial sealing rib 312.

[0097] Please refer to Figure 25 , a channel sealing ring 32 with an annular structure can also be sleeved at the lower end of the drainage channel 111. The bottom surface of the channel sealing ring 32 is a planar structure. When the water receiving tray 2 is located directly below the drainage channel 111, the bottom surface of the channel sealing ring 32 frictionally cooperates with the upper edge of the first axial sealing rib 312. By providing the channel sealing ring 32, when the water receiving tray 2 is in the first position directly below the drainage channel 111, the channel sealing ring 32 cooperates with the first axial sealing rib 312, which can effectively seal the gap between the top of the water receiving tray 2 and the bottom of the drainage channel 111, ensuring that the liquid falling from the drainage channel 111 can be reliably collected by the water receiving tray 2, thereby achieving a better effect of preventing splashing and surging of water.
