Description

Technical Field

[0001] The invention relates to the technical field of toilets, and in particular to a water-leakage-proof dry-wet separation mechanism for a toilet. Background Art

[0002] Biodegradable toilets are a new type of toilet that has appeared in recent years. They can degrade human feces through microorganisms. They are particularly suitable for use in indoor environments such as RVs, yachts, and nursing homes for caring for elderly people with limited mobility where it is inconvenient to collect water or discharge waste.

[0003] In order to prevent the culture medium of biodegradable toilets from undergoing anaerobic reactions that produce harmful gases due to excessive humidity, some biodegradable toilets are equipped with a liquid collection tray that can be opened or stored under the excretion channel. When urinating or flushing, the liquid collection tray is located below the excretion channel, collecting urine or flushing water and directing it to the urine collection box or sewage tank. When defecating, the liquid collection tray no longer blocks the bottom of the excretion channel, and the excrement falls directly into the biodegradable container below the excretion channel.

[0004] However, when the above-mentioned liquid collection plate is located directly below the drainage channel, there will inevitably be a circumferential gap of varying sizes between the drainage channel and the liquid collection plate. When collecting liquid with a large impact force or a large flow rate, the circumferential gap is prone to water gushing or splashing, and leaking into the biodegradable container, thereby affecting the stability of the aerobic reaction of the culture medium.

[0005] Solving the above problems has become a top priority. Summary of the Invention

[0006] In order to solve the technical problem that the existing water receiving tray has a circumferential gap that is prone to water leakage when it is located directly below the excretion channel, the present invention provides a toilet anti-leakage dry-wet separation mechanism.

[0007] The technical solution is as follows:

[0008] The first aspect of the present application relates to a toilet anti-leakage wet and dry separation mechanism, comprising a toilet body and a water collecting pan, wherein a toilet bowl is provided on the upper part of the toilet body, and a drainage channel is provided at the bottom of the toilet bowl, and the water collecting pan can be mounted on the toilet body so as to be rotatable in the horizontal direction, so that the water collecting pan can rotate back and forth in the horizontal direction between a first position directly below the drainage channel and a second position outside the drainage channel, and further comprising a water-leakage-proof structure mounted on the water collecting pan and / or the drainage channel, wherein the water-leakage-proof structure can seal the circumferential gap between the top of the water collecting pan and the bottom of the drainage channel when the water collecting pan is in the first position.

[0009] When the above-mentioned toilet anti-leakage dry-wet separation mechanism is adopted, when the water receiving tray is located in the first position directly below the excretion channel, the anti-leakage structure can seal the circumferential gap between the top of the water receiving tray and the bottom of the excretion channel, thereby avoiding the problem of water leakage into the biodegradable container below, and further avoiding excessive humidity in the biodegradable container, ensuring the stability of the aerobic reaction of the culture medium, avoiding the occurrence of odors such as bad smells in the toilet, and protecting the health of the user.

[0010] In some embodiments, the water tray includes a water tray bottom plate and a water tray side baffle extending upward from the circumferential outer edge of the water tray bottom plate, the water tray side baffle and / or the water tray bottom plate can be horizontally rotatably mounted on the toilet body through a water tray operating mechanism, and the water tray bottom plate and / or the water tray side baffle are provided with a drainage structure connected thereto, and when the water tray is in the first position, the water tray bottom plate and the water tray side baffle are located directly below the drainage channel.

[0011] In some embodiments, the anti-leakage structure includes a water receiving pan sealing ring provided on the side baffle of the water receiving pan, and the water receiving pan sealing ring is a circular ring structure. When the water receiving pan is in the first position, the lower end surface of the drainage channel is frictionally fitted or interference fit with the top of the water receiving pan sealing ring, so that the circumferential gap between the top of the water receiving pan and the bottom of the drainage channel can be sealed by the water receiving pan sealing ring.

[0012] In some embodiments, the anti-leakage structure includes a channel sealing ring provided on the drainage channel, which has a circular ring structure. When the water receiving tray is in the first position, the bottom of the channel sealing ring is frictionally fitted or interference fit with the upper edge of the side baffle of the water receiving tray, thereby being able to seal the circumferential gap between the top of the water receiving tray and the bottom of the drainage channel through the channel sealing ring.

[0013] In some embodiments, the anti-leakage structure includes a water receiving pan sealing ring installed on the side baffle of the water receiving pan and a channel sealing ring installed on the drainage channel. The water receiving pan sealing ring and the channel sealing ring are both circular ring structures. When the water receiving pan is in the first position, the bottom of the channel sealing ring and the top of the water receiving pan sealing ring are frictionally fitted or interference fit, so that the circumferential gap between the top of the water receiving pan and the bottom of the drainage channel can be sealed by the cooperation of the water receiving pan sealing ring and the channel sealing ring.

[0014] In some embodiments, the water receiving tray sealing ring has a first radial sealing band extending radially along the bottom plate of the water receiving tray;

[0015] or,

[0016] At least one circle of first axial sealing ribs extending axially away from the bottom plate of the water receiving tray is coaxially provided on the top of the water receiving tray sealing ring, and the diameters of the first axial sealing ribs are different.

[0017] In some embodiments, the water receiving tray sealing ring is made of silicone, rubber, polyurethane, or polytetrafluoroethylene, and the water receiving tray sealing ring is directly fixed to the water receiving tray side baffle or fixed to the water receiving tray side baffle via a first positioning structure;

[0018] or,

[0019] The sealing ring of the water receiving pan made of elastic plastic material and the water receiving pan made of hard plastic material are integrally formed by adopting a two-color injection molding process.

[0020] In some embodiments, the bottom of the channel sealing ring has a second radial sealing band extending radially along the drainage channel;

[0021] or,

[0022] At least one circle of second axial sealing ribs extending axially along the discharge channel is coaxially provided on the bottom of the channel sealing ring, and the diameters of the second axial sealing ribs are different.

[0023] In some embodiments, the channel sealing ring is made of silicone, rubber, polyurethane, or polytetrafluoroethylene, and the channel sealing ring is directly fixed on the excretion channel or fixed on the excretion channel through a second positioning structure.

[0024] In some embodiments, the water tray operating mechanism includes a lever, a rotating shaft, a linkage assembly, and a water tray connecting seat integrally formed on the water tray side baffle and / or the water tray bottom plate. The rotating shaft can be rotatably installed vertically on the toilet body. The upper end of the rotating shaft passes through the toilet body upward and is synchronously rotatably installed with the lever. The lower end of the rotating shaft is located inside the toilet body and is connected to the water tray connecting seat through the linkage assembly, so that the water tray bottom plate and the water tray side baffle can be moved back and forth between the first position and the second position by rotating the lever.

[0052] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0053] like Figure 1-Figure 27 As shown, a toilet anti-leakage wet-dry separation mechanism mainly includes a toilet body 1 and a water collecting tray 2. A toilet bowl 11 is provided on the upper part of the toilet body 1, and a drainage channel 111 is provided at the bottom of the toilet bowl 11. Excrement can fall into a biodegradable container below (not shown in the figure) through the drainage channel 111, and the water collecting tray 2 is located between the drainage channel 111 and the biodegradable container.

[0054] The water collection pan 2 is used to collect urine during urination, flushing water for washing the buttocks, or flushing the toilet, and directs the collected liquid to a urine collection tank, a sewage tank, or a gray water tank. Specifically, the water collection pan 2 is mounted on the toilet body 1 so as to be horizontally rotatable, thereby enabling the water collection pan 2 to rotate horizontally between a first position directly below the drainage channel 111 and a second position outside the drainage channel 111.

[0055] When the water tray 2 is in the first position, the water tray 2 is located directly below the drainage channel 111, and the liquid falling from the drainage channel 111 is collected by the water tray 2. When the water tray 2 is in the second position, the water tray 2 no longer blocks the lower end of the drainage channel 111, and the excrement falling from the drainage channel 111 falls into the biodegradable container below.

[0056] The water receiving tray 2 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 constitute a disc-shaped structure with an open top, which is used to collect urine during urination or flushing water for washing the buttocks or flushing water for flushing the toilet.

[0057] The water tray side baffle 22 and / or the water tray bottom plate 21 are provided with a drainage structure 23 connected thereto, that is, the drainage structure 23 is arranged on the water tray side baffle 22 or the water tray bottom plate 21, or the drainage structure 23 is located on both the water tray bottom plate 21 and the water tray side baffle 22. The drainage structure 23 is used to guide the collected liquid into a urine collection box or a sewage tank.

[0058] The drainage structure 23 preferably adopts a tubular drainage pipe, which is not prone to water leakage such as gushing due to excessive flow, thereby further improving the overall anti-leakage performance of the toilet water receiving tray.

[0059] Among them, the inlet of the drain pipe is a drain port 223 opened on the side baffle 22 of the water receiving tray, and the bottom of the drain port 223 is lower than or flush with the top surface of the water receiving tray bottom plate 21, and the bottom of the drain port 223 is lower than or flush with the top surface of the water receiving tray bottom plate 21, so that the liquid collected in the water receiving tray 2 can be better drained, avoiding the water receiving tray 2 from stinking due to the inability to completely drain the liquid.

[0060] In this embodiment, the water tray side baffles 22 can be arranged perpendicular to the water tray bottom plate 21, and the water tray side baffles 22 can also be arranged to be inclined from top to bottom and inward, so that the water tray 2 has a larger volume.

[0061] In this embodiment, the water receiving pan connecting seat 244 on the water receiving pan side baffle 22 and / or the water receiving pan bottom plate 21, that is, the water receiving pan connecting seat 244 is set on the water receiving pan side baffle 22 or the water receiving pan bottom plate 21, or the water receiving pan connecting seat 244 is located on the water receiving pan bottom plate 21 and the water receiving pan side baffle 22 at the same time, the water receiving pan connecting seat 244 is used to connect to the water receiving pan operating mechanism 24, and the water receiving pan operating mechanism 24 is used to control the rotation of the water receiving pan 2.

[0062] Specifically, the water tray operating mechanism 24 includes a lever 241, a rotating shaft 242 and a linkage assembly 243. The rotating shaft 242 can be rotatably installed vertically on the toilet body 1. The upper end of the rotating shaft 242 passes through the toilet body 1 upward and is synchronously rotatably installed with the lever 241. The lower end of the rotating shaft 242 is located inside the toilet body 1 and is connected to the water tray connecting seat 244 through the linkage assembly 243, so that the water tray bottom plate 21 and the water tray side baffle 22 can be moved back and forth between the first position and the second position by rotating the lever 241.

[0063] The linkage component 243 in this embodiment has two implementation modes:

[0064] Connection component 243 Example 1: Please see Figure 1 and Figure 2 The connecting assembly 243 includes a connecting rod 234a and a hinge 243b. The toilet body 1 is provided with a connecting member mounting plate 12, which is provided with an arcuate slot 13 that mates with the hinge 243b. The hinge 243b is slidably mounted within the arcuate slot 13. The connecting rod 234a is horizontally disposed, one end of which is synchronously rotatably mounted on the lower end of the rotating shaft 242. The water tray connection base 244 of the water tray 2 is hingedly mounted to the other end of the connecting rod 234a via the hinge 243b. Therefore, by virtue of the structural design of the arcuate slot 13, the operator can rotate the lever 241 back and forth horizontally to rotate the water tray 2 back and forth between a first position directly below the drainage channel 111 of the toilet body 1 and a second position outside the drainage channel 111.

[0065] Connection component 243 Example 2: Please see Figure 3 The connecting assembly 243 includes a connecting rod 234a and a sliding engagement rod 243b'. The toilet body 1 is also provided with a connecting member mounting plate 12. A mating groove 13' is mounted on the connecting member mounting plate 12, which slidably engages with the sliding engagement rod 243b'. The end of the mating groove 13', which is closest to the water tray 2, extends through the connecting member mounting plate 12. Furthermore, a linear groove 243a1 is formed on the connecting rod 234a, extending along its length. A circular slider 243c is hingedly connected to the lower end of the water tray connection seat 244 of the water tray 2. This circular slider 243c can both slide along the linear groove 243a1 and rotate within the linear groove 243a1. Furthermore, one end of the sliding engagement rod 243b' is slidably inserted into the mating groove 13', while the other end is hingedly connected to the water tray connection seat 244 of the water tray 2.

[0066] The operator rotates the lever 241 back and forth in the horizontal direction to rotate the water receiving tray 2 back and forth between a first position located directly below the drainage channel 111 of the toilet bowl 11 and a second position located outside the drainage channel 111 .

[0067] Regardless of embodiment 1 of the connection component 243 or embodiment 2 of the connection component 243, the lower end of the rotating shaft 242 is preferably rotatably connected to the mounting plate 12, thereby improving the reliability of the installation of the rotating shaft 242.

[0068] This embodiment further includes a water leakage prevention structure 3 installed on the water receiving tray 2 and / or the drainage channel 111. The water leakage prevention structure 3 has the following three implementation modes:

[0069] Implementation method 1 of anti-leakage structure 3:

[0070] See Figure 6 and Figure 7 The anti-leakage structure 3 is only provided on the water receiving tray 2, that is, the anti-leakage structure 3 only includes a water receiving tray sealing ring 31 provided on the water receiving tray side baffle 22. The water receiving tray sealing ring 31 is a circular ring structure. When the water receiving tray 2 is in the first position, the lower end surface of the drainage channel 111 and the top of the water receiving tray sealing ring 31 are frictionally fitted or interference fit, so that the circumferential gap between the top of the water receiving tray 2 and the bottom of the drainage channel 111 can be sealed by the water receiving tray sealing ring 31.

[0071] Implementation method 2 of anti-leakage structure 3:

[0072] See Figure 9 and Figure 10 The anti-leakage structure 3 is only provided on the drain channel 111, that is, the anti-leakage structure 3 only includes a channel sealing ring 32 provided on the drain channel 111. The channel sealing ring 32 is a circular ring structure. When the water receiving tray 2 is in the first position, the bottom of the channel sealing ring 32 is frictionally fitted or interference fit with the upper edge of the water receiving tray side baffle 22, so that the circumferential gap between the top of the water receiving tray 2 and the bottom of the drain channel 111 can be sealed by the channel sealing ring 32.

[0073] Implementation method 3 of anti-leakage structure 3:

[0074] See Figure 4 、 Figure 5 and Figure 8 The water receiving pan 2 and the drainage channel 111 are both provided with a water leakage prevention structure 3. Specifically, the water leakage prevention structure 3 includes a water receiving pan sealing ring 31 mounted on the water receiving pan side baffle 22 and a channel sealing ring 32 mounted on the drainage channel 111. Both the water receiving pan sealing ring 31 and the channel sealing ring 32 are annular structures. When the water receiving pan 2 is in the first position, the bottom of the channel sealing ring 32 and the top of the water receiving pan sealing ring 31 form a friction fit or an interference fit. Thus, the cooperation between the water receiving pan sealing ring 31 and the channel sealing ring 32 can seal the circumferential gap between the top of the water receiving pan 2 and the bottom of the drainage channel 111.

[0075] The anti-leakage structure 3 of the above three embodiments can seal the circumferential gap between the top of the water receiving tray 2 and the bottom of the excretion channel 111, thereby avoiding the problem of water leakage into the biodegradable container below, and further avoiding excessive humidity in the biodegradable container, ensuring the stability of the aerobic reaction of the culture medium, avoiding the occurrence of odors such as bad smells in the toilet, and protecting the health of the user.

[0076] The following is a detailed description of various embodiments of the water receiving tray 2 provided with the water receiving tray sealing ring 31:

[0077] Water tray 2 embodiment 1:

[0078] See Figure 11-13 A water receiving pan sealing ring 31 with a circular ring structure is provided on the water receiving pan side baffle 22. The water receiving pan sealing ring 31 has a first radial sealing band 311 extending radially along the water receiving pan bottom plate 21. The first radial sealing band 311 is a circular thin plate structure. When the water receiving pan 2 is located directly below the drainage channel 111 of the toilet bowl 11 of the toilet body 1, the first radial sealing band 311 can seal the circumferential gap between the drainage channel 111 and the water receiving pan 2.

[0079] The water tray seal ring 31 of this embodiment is entirely composed of the first radial sealing band 311. Any position on the bottom surface of the water tray seal ring 31 can be fixedly connected to the upper edge of the water tray side baffle 22. In this embodiment, the outer edge of the first radial sealing band 311 is fixedly connected to the upper edge of the water tray side baffle 22.

[0080] Furthermore, the water pan seal ring 31 can be made of common elastic sealing materials such as silicone, rubber, polyurethane, or polytetrafluoroethylene, and the water pan seal ring 31 is fixedly connected to the water pan side baffle 22 by bonding. Alternatively, the water pan seal ring 31 made of elastic plastic material and the water pan 2 made of hard plastic material can be integrally formed using a two-color injection molding process, thereby increasing the strength of the connection between the two and making them more durable.

[0081] See Figure 4 and Figure 5 When the water receiving tray 2 is located directly below the drainage channel 111 of the toilet bowl 11 of the toilet body 1, if a channel sealing ring 32 is provided on the drainage channel 111, the top surface of the first radial sealing band 311 and the bottom surface of the channel sealing ring 32 are frictionally fitted or interference fit, thereby sealing the circumferential gap between the drainage channel 111 and the water receiving tray 2.

[0082] See Figure 6 When the water receiving tray 2 is located directly below the drainage channel 111 of the toilet bowl 11 of the toilet body 1, if no channel sealing ring 32 is provided on the drainage channel 111, the top surface of the first radial sealing band 311 and the bottom surface of the drainage channel 111 are frictionally fitted or interference fit, thereby sealing the circumferential gap between the drainage channel 111 and the water receiving tray 2.

[0083] Water tray 2 embodiment 2:

[0084] See Figure 14The main structure of the water receiving tray 2 of this embodiment is exactly the same as that of the water receiving tray 2 embodiment 1. The difference is that the bottom of the water receiving tray sealing ring 31 has a first positioning structure 313 that is compatible with the water receiving tray side baffle 22. The water receiving tray sealing ring 31 is installed on the water receiving tray side baffle 22 through the first positioning structure 313, thereby further improving the reliability of the water receiving tray sealing ring 31 installed on the water receiving tray 2 and extending its service life.

[0085] The first positioning structure 313 of this embodiment is a positioning ring extending axially along the water tray base plate 21. Together with the first radial sealing band 311, the first positioning structure 313 forms an L-shaped cross-section of the water tray sealing ring 31. The positioning ring of this embodiment is mounted on the inner wall of the water tray side baffle 22 using common methods such as snap-fit ​​or adhesive fastening. The first positioning structure 313 extends radially inward from the upper edge of the positioning ring along the water tray base plate 21.

[0090] Water tray 2 embodiment 5:

[0091] See Figure 17 The main structure of the water receiving tray 2 of this embodiment is exactly the same as that of the water receiving tray 2 embodiment 4, the difference being that the positioning ring of this embodiment is located in the middle of the bottom surface of the first positioning structure 313, and the positioning ring is installed on the inner wall of the water receiving tray side baffle 22 by common methods such as snap-fitting or adhesive fixation, and the first positioning structure 313 and the positioning ring together make the cross section of the water receiving tray sealing ring 31 a "T"-shaped structure, that is, the first positioning structure 313 extends from the upper edge of the positioning ring along the radial direction of the water receiving tray bottom plate 21 to the inner and outer sides.

[0092] Water tray 2 embodiment 6:

[0093] See Figure 18The main structure of the water receiving tray 2 of this embodiment is exactly the same as that of the water receiving tray 2 in embodiment 5, the difference being that the positioning ring is installed on the outer wall of the water receiving tray side baffle 22 by common means such as snap-fitting or adhesive fixation.

[0094] Water tray 2 embodiment 7:

[0095] See Figure 19 The main structure of the water tray 2 of this embodiment is identical to that of the water tray 2 of Example 2. The difference lies in the following: the first positioning structure 313 comprises two positioning rings extending axially along the water tray base plate 21. The two positioning rings are attached to the inner and outer walls of the water tray side baffle 22 either by snap-fitting or by common methods such as adhesive fixation. The outer edges of the first radial sealing band 311 are flush with the outer walls of the two positioning rings. In other words, the first radial sealing band 311 and the two positioning rings together form an "N"-shaped cross-section of the water tray sealing ring 31.

[0096] Water tray 2 embodiment 8:

[0097] See Figure 20 The main structure of the water receiving tray 2 of this embodiment is exactly the same as that of the water receiving tray 2 embodiment 7, the difference being that the outer edge of the first radial sealing band 311 is flush with the outer wall of the positioning ring located on the outside, and the inner edge of the first radial sealing band 311 protrudes from the outer wall of the positioning ring located on the inside, that is, the first radial sealing band 311 and the two circles of positioning rings together make the cross section of the water receiving tray sealing ring 31 an "F"-shaped structure.

[0098] Water tray 2 embodiment 9:

[0099] See Figure 21 The main structure of the water receiving tray 2 of this embodiment is exactly the same as that of the water receiving tray 2 in embodiment 8.

[0100] Water receiving tray 2 embodiment 10:

[0101] See Figure 22The main structure of the water tray 2 of this embodiment is identical to that of the water tray 2 of embodiment 4, with the following differences: the first positioning structure 313 is a ring of annular ribs extending axially along the water tray base plate 21. This rib is located at the inner edge of the first radial sealing band 311. Together, the first positioning structure 313 and the first radial sealing band 311 give the water tray sealing ring 31 an L-shaped cross-section. Furthermore, a positioning groove 221 is formed in the upper edge of the water tray side baffle 22, which is compatible with the annular rib. This positioning groove 221 extends along the inner wall of the water tray side baffle 22. The annular rib is mounted in the positioning groove 221 either by snap-fitting or by adhesive fixation, a common method.

[0102] Water tray 2 embodiment 11:

[0103] See Figure 23 The main structure of the water tray 2 of this embodiment is identical to that of the water tray 2 of embodiment 10. The differences are: an annular rib is located in the middle of the bottom surface of the first radial sealing band 311. The first positioning structure 313 and the first radial sealing band 311 together form a T-shaped cross-section of the water tray seal ring 31. A positioning groove 221 is formed in the middle of the upper edge of the water tray side baffle 22. The annular rib is also mounted in the positioning groove 221 using either a snap-fit ​​or conventional methods such as adhesive fixation.

[0104] Water tray 2 embodiment 12:

[0105] See Figure 24 The main structure of the water tray 2 of this embodiment is identical to that of the water tray 2 of the first embodiment, except for the structure of the water tray sealing ring 31. The water tray sealing ring 31 includes a first positioning structure 313 and a first axial sealing rib 312 disposed on top of the first positioning structure 313 and extending axially away from the water tray base plate 21. In this embodiment, the first positioning structure 313 is a circular thin plate structure extending radially along the water tray base plate 21. The first axial sealing rib 312 is located in the middle of the top surface of the first positioning structure 313. Together, the first positioning structure 313 and the first axial sealing rib 312 form an inverted T-shaped cross-section of the water tray sealing ring 31.

[0106] It should be noted that the top of the first positioning structure 313 may also be coaxially provided with multiple circles of first axial sealing ribs 312 extending axially away from the water receiving tray bottom plate 21 along the water receiving tray bottom plate 21, and at the same time, the diameters of the first axial sealing ribs 312 are different.

[0107] See Figure 8When the water receiving tray 2 is located directly below the drainage channel 111 of the toilet bowl 11 of the toilet body 1, if a channel sealing ring 32 is provided on the drainage channel 111, the upper edge of the first axial sealing rib 312 frictionally fits with the bottom surface of the channel sealing ring 32, thereby sealing the circumferential gap between the drainage channel 111 and the water receiving tray 2.

[0108] See Figure 7 When the water receiving tray 2 is located directly below the drainage channel 111 of the toilet bowl 11 of the toilet body 1, if no channel sealing ring 32 is provided on the drainage channel 111, the upper edge of the first axial sealing rib 312 frictionally fits with the bottom surface of the drainage channel 111, thereby sealing the circumferential gap between the drainage channel 111 and the water receiving tray 2.

[0109] Water tray 2 embodiment 13:

[0110] See Figure 25 The main structure of the water tray 2 of this embodiment is identical to that of the water tray 2 of embodiment 12, with the following differences: the first positioning structure 313 is an L-shaped structure. The top of the first positioning structure 313 is a thin plate extending radially along the water tray bottom plate 21. The inner edge of the first positioning structure 313 extends axially along the water tray bottom plate 21 toward the water tray bottom plate 21, forming an annular structure that is compatible with the water tray side baffle 22. The outer peripheral surface of the first positioning structure 313 mates with the inner wall of the water tray side baffle 22, and can be fixed by either a snap-fit ​​method or a conventional method such as adhesive fixing. The first axial sealing rib 312 extends from the outer edge of the first positioning structure 313 along the axial direction of the water tray bottom plate 21 away from the water tray bottom plate 21.

[0111] Water tray 2 embodiment 14:

[0112] See Figure 26 The main structure of the water receiving tray 2 of this embodiment is exactly the same as that of the water receiving tray 2 embodiment 1, the difference being that the upper edge of the water receiving tray side baffle 22 has a circle of sealing ring mounting seat 222 that is compatible with the water receiving tray sealing ring 31. The sealing ring mounting seat 222 can be of any structure as long as the top surface of the sealing ring mounting seat 222 is a planar structure that is compatible with the first radial sealing band 311. The first radial sealing band 311 is fixed to the top surface of the sealing ring mounting seat 222 by conventional means such as bonding.

[0113] Water tray 2 embodiment 15:

[0114] See Figure 27The main structure of the water receiving tray 2 of this embodiment is exactly the same as that of the water receiving tray 2 embodiment 14, the difference being that the sealing ring mounting seat 222 is a thin plate structure extending radially inward from the upper edge of the water receiving tray side baffle 22, and the water receiving tray sealing ring 31 includes a first positioning structure 313 and a first axial sealing rib 312, wherein the first positioning structure 313 is a circular thin plate structure extending radially along the water receiving tray bottom plate 21, and the top surface of the first positioning structure 313 and the bottom surface of the sealing ring mounting seat 222 are fixedly connected by conventional means such as bonding, and the first axial sealing rib 312 extends from the inner edge of the first positioning structure 313 along the axial direction of the water receiving tray bottom plate 21 toward and away from the water receiving tray bottom plate 21.

[0115] The following describes various embodiments of the channel sealing ring 32 on the discharge channel 111 in detail:

[0116] Channel sealing ring 32 embodiment 1:

[0117] See Figure 5 、 Figure 8 and Figure 10 The channel sealing ring 32 is a circular ring structure, which is sleeved on the lower end of the discharge channel 111. The bottom of the channel sealing ring 32 has a circle of second radial sealing belt 321 extending radially along the discharge channel 111. The second radial sealing belt 321 is a circular ring thin plate structure.

[0118] See Figure 5 and Figure 8 When the water receiving pan 2 is located directly below the drainage channel 111 of the toilet bowl 11 of the toilet body 1, if a water receiving pan sealing ring 31 is provided on the water receiving pan 2, the bottom surface of the second radial sealing band 321 and the top surface of the water receiving pan sealing ring 31 are frictionally fitted or interference fit, thereby being able to seal the circumferential gap between the drainage channel 111 and the water receiving pan 2.

[0119] See Figure 10 When the water receiving tray 2 is located directly below the drainage channel 111 of the toilet bowl 11 of the toilet body 1, if the water receiving tray sealing ring 31 is not provided on the water receiving tray 2, the bottom surface of the second radial sealing belt 321 and the upper edge of the water receiving tray side baffle 22 are frictionally fitted or interference fit, thereby being able to seal the circumferential gap between the drainage channel 111 and the water receiving tray 2.

[0120] Furthermore, in order to reduce the resistance of the second radial sealing belt 321 to the rotation of the water tray 2, when the water tray 2 is located directly below the excretion channel 111 of the toilet bowl 11 of the toilet body 1, the bottom surface of the second radial sealing belt 321 and the upper edge of the water tray side baffle 22 are preferably friction-fitted.

[0121] Furthermore, in order to further reduce the resistance of the second radial sealing belt 321 to the rotation of the water tray 2, the upper edge of the water tray side baffle 22 preferably adopts an upwardly protruding arc surface structure. Not only is the surface contact between the bottom surface of the second radial sealing belt 321 and the upper edge of the water tray side baffle 22 optimized to line contact, thereby reducing friction resistance, but the arc surface structure can also avoid excessive damage to the second radial sealing belt 321 caused by repeated friction, thereby improving its service life.

[0122] The channel sealing ring 32 is made of silicone, rubber, polyurethane, or polytetrafluoroethylene, and is fixed directly to the drainage channel 111 or fixed to the drainage channel 111 via a second positioning structure 323. The channel sealing ring 32 is fixed to the drainage channel 111 by common means such as snapping or bonding.

[0123] Channel sealing ring 32 embodiment 2:

[0124] See Figure 4 and Figure 9 The main structure of the channel sealing ring 32 of this embodiment is exactly the same as that of the channel sealing ring 32 in embodiment 1, the difference being that a circle of second axial sealing ribs 322 is integrally formed at the bottom of the channel sealing ring 32, and the second axial sealing ribs 322 extend downward.

[0125] See Figure 4 When the water receiving pan 2 is located directly below the drainage channel 111, if a water receiving pan sealing ring 31 is provided on the water receiving pan 2, the lower edge of the second axial sealing rib 322 frictionally fits with the top surface of the water receiving pan sealing ring 31, thereby sealing the circumferential gap between the drainage channel 111 and the water receiving pan 2.

[0126] See Figure 9 When the water receiving pan 2 is located directly below the drainage channel 111, if the water receiving pan sealing ring 31 is not provided on the water receiving pan 2, the lower edge of the second axial sealing rib 322 frictionally fits with the upper edge of the water receiving pan side baffle 22, thereby sealing the circumferential gap between the drainage channel 111 and the water receiving pan 2.

[0127] Therefore, by providing a second axial sealing rib 322 with a thin film structure at the bottom of the channel sealing ring 32, and utilizing the friction fit between the lower edge of the second axial sealing rib 322 and the counterpart, it is possible to effectively seal the circumferential gap between the top of the water receiving tray 2 and the bottom of the drainage channel 111, and reduce the interference effect of the channel sealing ring 32 on the rotation of the water receiving tray 2, i.e., the friction force, thereby ensuring the smooth rotation of the water receiving tray 2.

[0128] It should be pointed out that the second radial sealing band 321 of this embodiment serves as an installation limit, which can prevent the channel sealing ring 32 from moving upward after long-term use and failing to provide a good sealing effect.

[0129] At the same time, one or more circles of second axial sealing ribs 322 can be set at the bottom of the second radial sealing band 321. When multiple circles of second axial sealing ribs 322 are set, the diameter of each second axial sealing rib 322 gradually increases, which can ensure an excellent sealing effect and avoid water leakage.

[0130] When only one circle of second axial sealing ribs 322 is provided, if the water receiving tray 2 adopts any one of Examples 1 to 11, the lower edge of the second axial sealing rib 322 is close to the inner edge of the first radial sealing band 311. Usually, the lower edge of the second axial sealing rib 322 is 2 mm to 3 mm away from the inner edge of the first radial sealing band 311, which not only ensures the sealing performance and avoids the occurrence of gaps due to incomplete rotation, but also avoids the problem of odor caused by accumulated water on the top of the first radial sealing band 311.

[0131] Furthermore, the thickness of the lower part of the second axial sealing rib 322 gradually decreases from top to bottom, thereby achieving a good sealing effect and minimizing the friction with the first radial sealing belt 311 as much as possible, so that the rotation of the toilet water tray can be smoother.

[0132] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention. Such changes fall within the scope of protection of the present invention.
