Such a configuration can avoid a friction between the seat cover sealing ring 4 and the hole wall of the seat ring hole 11. In addition, a lower opening of the seat ring hole 11 is sealed through the seat cover sealing ring 4 and the second sealing strip 32, so that the aerosol can be prevented from overflowing outwards from the seat ring hole 11.

A shape of the second sealing strip 32 may be selected according to the shape of the seat ring hole 11. If the seat ring 1 is a complete seat ring, the second sealing strip 32 has a shape of a sealing ring. If the seat ring 1 is a seat ring with a gap, the second sealing strip 32 has a shape of a major arc.

In one embodiment, the seat ring hole 11 has a closed contour line, the first sealing strip 31 is a first sealing ring (e.g., a first closed ring), and the second sealing strip 32 is a second sealing ring (e.g., a second closed ring). In other words, when the seat ring 1 is a complete seat ring without a gap, the first sealing strip 31 and the second sealing strip 32 are both annular sealing strips.

In one embodiment, as shown in FIGS. 1-3, a front end of the seat ring 1 includes a seat ring gap 12 communicated with the seat ring hole 11, and a front end of the seat cover sealing ring 4 includes a seat cover sealing body 41 configured to seal the seat ring gap 12.

When the seat cover 2 covers the seat ring 1, the seat cover sealing body 41 is disposed in the seat ring gap 12 and contacted with a side wall of the seat ring gap 12.

In this embodiment, the seat ring 1 includes a gap. The seat ring gap 12 is disposed at the front end of the seat ring 1, and the seat ring gap 12 is communicated with the seat ring hole 11. The front end of the seat cover sealing ring 4 includes the seat cover sealing body 41, and the seat cover sealing body 41 is configured to seal the seat ring gap 12.

When the seat cover 2 covers the seat ring 1, the seat cover sealing body 41 is disposed in the seat ring gap 12, and the seat cover sealing body 41 is in sealing contact with a side wall of the seat ring gap 12, so that the aerosol can be prevented from overflowing from the seat ring gap 12.

In one embodiment, the seat cover sealing body 41 is integrally formed at the front end of the seat cover sealing ring 4.

In one embodiment, as shown in FIGS. 1 and 2, the seat ring sealing element 3 further comprises third sealing strips 33, and the third sealing strips 33 are disposed on two sides of a lower opening of the seat ring gap 12.

When the seat cover 2 covers the seat ring 1, the seat cover sealing body 41 is disposed in the seat ring gap 12, the seat cover sealing body 41 is in clearance fit with the side wall of the seat ring gap 12, and the seat cover sealing body 41 is contacted with the third sealing strip 33.

In this embodiment, the seat ring sealing element 3 further comprises the two third sealing strips 33. The two third sealing strips 33 are disposed on two sides of the lower opening of the seat ring gap 12.

When the seat cover 2 covers the seat ring 1, the seat cover sealing body 41 is inserted into the seat ring gap 12, the seat cover sealing body 41 is in clearance fit with the side wall of the seat ring gap 12, the seat cover sealing body 41 is in sealing contact with the third sealing strip 33. Such a configuration can avoid a friction between the seat cover sealing body 41 and the side wall of the seat ring gap 12 and prevent the aerosol from overflowing from the seat ring gap 12 by sealing the lower opening of the seat ring gap 12 through the seat cover sealing body 41 and the third sealing strip 33.

In one embodiment, the third sealing strip 33 is connected between the first sealing strip 31 and the second sealing strip 32. The first sealing strip 31, the second sealing strip 32, and the third sealing strip 33 form a closed sealing structure.

In one embodiment, the first sealing strip 31, the second sealing strip 32, and the third sealing strip 33 are integrally formed.

In one embodiment, as shown in FIG. 1, the bottom portion of the seat cover 2 is provided with a support rib 21 in a circle, and the seat cover sealing ring 4 is connected with the support rib 21. The support rib 21 is a plastic piece, and the support rib 21 provides support for the seat cover sealing ring 4.

In one embodiment, as shown in FIG. 1, the seat cover sealing ring 4 surrounds an outer surface of the support rib 21 to improve mounting stability of the seat cover sealing ring 4.

FIG. 4 is a schematic diagram of a buffer air cavity formed between a seat cover sealing ring and a support rib. In one embodiment, as shown in FIG. 4, at least one buffer air cavity 5 is formed between the seat cover sealing ring 4 and the support rib 21, and a channel 6 configured to allow air to flow into or from the buffer air cavity 5 is further formed between the seat cover sealing ring 4 and the support rib 21. When the seat cover 2 covers the seat ring 1, the channel 6 is communicated with the seat ring hole 11.

In this embodiment, the buffer air cavity 5 may be used as a decompression air bag. The buffer air cavity 5 is formed between the seat cover sealing ring 4 and the support rib 21. The air in the buffer air cavity 5 is charged and discharged through the channel 6. A vent of the channel 6 is located on the support rib 21.

When the seat cover 2 covers the seat ring 1, the channel 6 is communicated with the seat ring hole 11. Therefore, after the water is drained from the cavity 71 of the ceramic body 7 and when the cavity starts to store water, an air pressure in the cavity 71 is increased along with the rising water level, the air may enter the buffer air cavity 5 through the seat ring hole 11 and the channel 6, and the part of the seat cover sealing ring 4 corresponding to the buffer air cavity 5 can expand to buffer the air pressure. Thus, the toilet cover plate is effectively prevented from jumping due to the increase of the air pressure in the cavity 71.

In one embodiment, as shown in FIGS. 3 and 4, the buffer air cavity 5 is located at a rear portion of the seat cover 2. The space between the rear portion of the seat cover 2 and the seat ring 1 is large, so that it is advantageous to arrange the buffer air cavity 5 and allow the expansion and contraction of the seat cover sealing ring 4.

FIG. 5 is a schematic diagram of a bottom portion of a first sealing strip connected with an elastic membrane. In one embodiment, as shown in FIG. 5, a bottom portion of the first sealing strip 31 is connected with an elastic membrane 311, and the elastic membrane 311 extends towards the seat ring hole 11.

When the seat ring 1 covers the ceramic body 7, the elastic membrane 311 is located on the ceramic body 7.

When an inside air pressure of the elastic membrane 311 is greater than or equal to an outside air pressure of the elastic membrane, the elastic membrane 311 keeps in contact with the ceramic body 7.

When the outside air pressure of the elastic membrane 311 is greater than the inside air pressure of the elastic membrane, the elastic membrane 311 is at least partially separated from the ceramic body 7.

In this embodiment, the elastic membrane 311 is used as a check valve. The elastic membrane 311 is a rubber elastic sheet. The elastic membrane 311 is integrally arranged at the bottom portion of the first sealing strip 31. If necessary, the elastic membrane 311 may be arranged in a partial region of the first sealing strip 31. An upper end of the elastic membrane 311 is connected with the first sealing strip 31, and a lower end of the elastic membrane 311 extends toward the seat ring hole 11.

When the seat ring 1 covers the ceramic body 7, the lower end of the elastic membrane 311 is attached on the ceramic body 7.

At the moment of washing or flushing the ceramic body 7, the water enters the cavity 71 of the ceramic body 7, and the water level in the cavity 71 rises. Thus, the inside air pressure of the elastic membrane 311 is greater than the outside air pressure of the elastic membrane. Under the action of the inside air pressure, the elastic membrane 311 may expand outwards, and the lower end of the elastic membrane 311 can be more tightly attached to the top surface of the ceramic body 7. Thus, the elastic membrane 311 seals the ceramic body 7 to prevent the aerosol from overflowing.

After the siphon occurs in the ceramic body 7, the water in the cavity 71 of the ceramic body 7 is drained, and the air pressure in the cavity 71 becomes small or is decreased. Thus, the inside air pressure of the elastic membrane 311 is smaller than the outside air pressure of the elastic membrane. Under the action of the outside air pressure, the lower end of the elastic membrane 311 leaves the top surface of the ceramic body 7, and the elastic membrane 311 does not seal the ceramic body 7. Thus, the external air is timely supplied into the cavity 71 of the ceramic body 7 to maintain the balance between the inside air pressure and the outside air pressure and reduce the influence on the siphoning function.

In one embodiment, as shown in FIG. 5, the flexible membrane 311 is an arc-shaped membrane. When the seat ring 1 covers the ceramic body 7, a lower end and an arc-shaped portion of the arc-shaped membrane are attached to the ceramic body 7, so that the ceramic body 7 can be better sealed.

In one embodiment, as shown in FIG. 3 and FIG. 5, the elastic membrane 311 is arranged at a rear portion of the first sealing strip 31. The space in a rear end area of the seat ring 1 is large and thus facilitates the arrangement of the elastic membrane 311.

In one embodiment, as shown in FIG. 1 and FIG. 3, a front end of the seat cover 2 is provided with a hand clasping groove 22 to facilitate a user to lift the seat cover 2.

FIG. 6 is a three-dimensional diagram of a toilet according to an example of the present disclosure. As shown in FIG. 6, a toilet provided by an embodiment of the present disclosure comprises a ceramic body 7 and the toilet cover plate according to any of the foregoing embodiments, and the seat ring 1 and the seat cover 2 are respectively mounted on the ceramic body 7 through a pivot shaft 8.

When the toilet cover plate covers the ceramic body 7, the first sealing strip 31 is contacted with the ceramic body 7, and the seat cover sealing ring 4 is contacted with the seat ring 1.

The toilet provided by the present disclosure comprises the ceramic body 7 and the toilet cover plate.

For the structure, construction, and working principle of the toilet cover plate are described above.

FIG. 7 is a flow chart of a method 100 for cleaning the toilet body according to a first example of the present disclosure. The method 100 for cleaning the toilet may be performed by the toilet cover plate according to any of the foregoing embodiments. The toilet cover plate is configured to perform an operation, function, or the like as described in the present disclosure. The toilet body cleaned by the method may be the ceramic body 7 according to any of the foregoing embodiments.

At act S101, a user may connect the elastic membrane 311 connected with the seat ring 1 of the toilet. As noted above, the bottom portion of the first sealing strip 31 may be connected with seat ring 1 via the elastic membrane 311, and the elastic membrane 311 may extend towards the seat ring hole 11.

At act S102, the user may close the seat ring 1 and the seat cover 2 to cover the toilet body and allow the elastic membrane 311 to contact the toilet body.

At act S103, the user may flush the toilet body with water to perform the cleaning.

At act S104, the flushing increases an inside air pressure of the elastic membrane 311 and when the inside air pressure of the elastic membrane 311 is greater than or equal to an outside air pressure of the elastic membrane 311, the elastic membrane 311 is maintained in contact with the toilet body.

Specifically, as noted above, the water enters the cavity 71 of the ceramic body 7, and the water level in the cavity 71 rises. Thus, the inside air pressure of the elastic membrane 311 is greater than the outside air pressure of the elastic membrane. Under the action of the inside air pressure, the elastic membrane 311 may expand outwards, and the lower end of the elastic membrane 311 can be more tightly attached to the top surface of the ceramic body 7. Thus, the elastic membrane 311 seals the ceramic body 7 to prevent the aerosol from overflowing.

At act S105, the toilet drains the water in the toilet body with the water.

At act S106, the draining decreases the inside air pressure of the elastic membrane and when the outside air pressure of the elastic membrane 311 is greater than the inside air pressure of the elastic membrane 311, the elastic membrane 311 is at least partially separated from the toilet body.

Specifically, as noted above, after the siphon occurs in the ceramic body 7, the water in the cavity 71 of the ceramic body 7 is drained, and the air pressure in the cavity 71 becomes small or is decreased. Thus, the inside air pressure of the elastic membrane 311 is smaller than the outside air pressure of the elastic membrane. Under the action of the outside air pressure, the lower end of the elastic membrane 311 leaves the top surface of the ceramic body 7, and the elastic membrane 311 does not seal the ceramic body 7. Thus, the external air is timely supplied into the cavity 71 of the ceramic body 7 to maintain the balance between the inside air pressure and the outside air pressure and reduce the influence on the siphoning function.

FIG. 8 is a flow chart of a method 100 for cleaning the toilet body according to a second example of the present disclosure. The method 200 for cleaning the toilet may be performed by the toilet cover plate according to any of the foregoing embodiments. The toilet cover plate is configured to perform an operation, function, or the like as described in the present disclosure. The toilet body cleaned by the method may be the ceramic body 7 according to any of the foregoing embodiments.

At act S201, a user may form at least one buffer air cavity 5 between the support rib 21 disposed at the bottom portion of the seat cover 2 and the seat cover sealing ring 4 surrounding the support rib 21.

At act S202, the user may form the channel 6 between the seat cover sealing ring 4 and the support rib 21 to allow the air to flow into and from the at least one buffer air cavity 5.

At act S203, the user may close the seat ring 1 and the seat cover 2 of the toilet to allow the channel in communication with the seat ring hole 11 of the seat ring 1.

At act S204, the toilet may supply water into the toilet body after a draining of the water. The draining of the water may be performed at act S105.

At act S205, the toilet allows the air in the toilet body to enter the buffer air cavity 5 through the seat ring hole 11 and the channel 6.

Specifically, as noted above, after the water is drained from the cavity 71 of the ceramic body 7 and when the cavity starts to store water, an air pressure in the cavity 71 is increased along with the rising water level, the air may enter the buffer air cavity 5 through the seat ring hole 11 and the channel 6, and the part of the seat cover sealing ring 4 corresponding to the buffer air cavity 5 can expand to buffer the air pressure. Thus, the toilet cover plate is effectively prevented from jumping due to the increase of the air pressure in the cavity 71.

Some acts of the method 200 may be performed before or at the same time some acts of the method 100 is performed. For example, acts S201, S202, and S203 may be performed before or at the same time the act S105 the method 100 is performed.

Some acts of the method 200 may be performed after the method 100 is performed. For example, S204 and S205 may be performed before or at the same time the act S105 the method 100 is performed.

According to the needs, the above embodiments may be combined to achieve the different technical effects.

The above only describes the principles and the embodiments of the present disclosure. Those of ordinary skill in the art should understand that other modifications can be made based on the principle of the present disclosure and should also be within the scope of protection of the present disclosure.
