Description

Technical Field

[0001] The present invention relates to the field of bathroom technology, and in particular to a toilet cover device and a toilet. Background Art

[0002] like Figure 15 As shown, the smart toilet in the related art includes a toilet cover device 1Q and a seat body 2Q. The toilet cover device 1Q includes a rear cover 10Q, a drying module, and a flushing module. The rear cover 10Q is installed on the top of the seat body 2Q. The drying module and the flushing module are hidden in the rear cover 10Q when not in use. The front end of the rear cover 10Q is provided with a drying extension port 11Q and a cleaning extension port 14Q. The spray rod of the flushing module can extend from the rear cover 10Q through the cleaning extension port 14Q to flush the human body. The drying channel of the drying module can extend from the drying extension port 11Q to dry the human body.

[0003] When men urinate while standing, urine can easily splash into the drying port 11Q and the washing port 14Q of the rear cover 10Q. To prevent urine from directly splashing into the drying port 11Q and the washing port 14Q, movable baffles 12Q are typically provided at these ports. However, there is a gap between the movable baffles 12Q and the rear cover 10Q, allowing urine and other contaminants to accumulate within this gap, creating an odor and making it difficult to clean. Urine and other contaminants can also easily enter the rear cover 10Q through this gap, causing mold and other contaminants.

[0004] The front end of the back cover 10Q typically includes a mounting hole 15Q extending vertically through the back cover 10Q. This hole 15Q allows for the fasteners that secure the back cover 10Q to pass through. A decorative cover 17Q is placed over the mounting hole 15Q. A gap exists between the inner wall of the mounting hole 15Q and the decorative cover 17Q, which can easily harbor dirt and grime, making it difficult to clean and affecting the user experience.

[0005] like Figure 16 As shown, the exposed area 16Q of the rear cover 10Q exposed to the pot surface space 20Q of the base 2Q is easily contaminated. For example, sewage in the pot surface space 20Q splashes onto the exposed area 16Q. However, the surface of the exposed area 16Q is uneven and difficult for users to clean.

[0006] like Figure 17 As shown, a fixing port 21Q for a brush ring nozzle is also provided on the toilet seat 2Q, and the brush ring nozzle is installed on the fixing port 21Q. The fixing port 21Q is provided at the top of the inner wall of the pot surface space 20Q of the seat 2Q. The fixing port 21Q is located in a corner, becoming a dead corner that is difficult to clean. Summary of the Invention

DETAILED DESCRIPTION

[0070] like Figures 1 to 4 As shown, Figures 1 to 4 The structure of a toilet 100 in an embodiment of the present application is shown. The toilet 100 includes a seat body 1 and a toilet cover device 2. The toilet cover device 2 is arranged at the upper end of the seat body 1.

[0071] like Figure 5 As shown, a pot surface cavity 11 is provided in the base body 1. The inner wall of the pot surface cavity 11 is a roughly concave arc-shaped structure. A pot surface space 111 is provided in the pot surface cavity 11, and the pot surface space 111 is used to accommodate human excrement. A sewage outlet 113 is provided at the bottom of the pot surface cavity 11, and an excrement inlet 112 is provided at the top of the pot surface cavity 11. The sewage outlet 113 and the excrement inlet 112 are both connected to the pot surface space 111. Human excrement enters the pot surface space 111 from the excrement inlet 112 and can be discharged from the pot surface space 111 through the sewage outlet 113.

[0072] like Figure 1 、 2 As shown, the toilet lid device 2 includes a housing 21, a seat 22, and a toilet lid 23. The housing 21 is disposed on top of the toilet lid 23 and located behind the pot surface cavity 11. The housing 21 is connected to the seat 1. The housing 21 can be a thin shell structure. A mounting cavity 210 is provided within the housing 21, which can accommodate components such as the control circuit board of the toilet lid device 2.

[0073] The seat ring 22 is an annular structure. The seat ring 22 can be in the shape of a roughly elliptical ring. The seat ring 22 and the toilet lid 23 are both rotatably connected to the shell 21. The seat ring 22 can be hinged to the shell 21. The seat ring 22 can rotate relative to the shell 21 around a horizontal axis of rotation. The seat ring 22 can rotate to a closed state covering the top of the seat body 1, and align the middle through hole of the seat ring 22 with the excrement inlet 112 of the pot surface cavity 11. In the closed state, the human body can sit on the seat ring 22, and the seat ring 22 can support the human body. The seat ring 22 can also rotate to an open state with one end facing upward. In the open state, men can urinate while standing without contaminating the seat ring 22.

[0074] When the seat ring 22 is in the open position, the lower edge of the seat ring 22 has a lower edge projection 221 vertically on the upper surface of the housing 21. This lower edge projection 221 is a line extending horizontally across the upper surface of the housing. The upper surface of the housing 21 is provided with a front edge 2101. This front edge 2101 is the edge of the upper surface of the housing 21 on the side of the housing 21 adjacent to the toilet bowl space 111. The upper surface of the housing 21 has no openings or gaps between this lower edge projection and the front edge 2101. The housing 21 also has a front end 21121, located at the end of the housing adjacent to the bowl space 111. This front end 21121 extends downward from the front edge 2101 of the upper surface of the housing. This front end 21121 can be flat or a smoothly curved surface. The front end 21121 of the housing 21 has no openings or gaps. This opening can be a through hole or a blind hole.

[0075] When the seat ring 22 is in the open state, the upper surface of the shell 21 in the area where the lower edge of the seat ring 22 is projected 221 to the front edge 2101 of the upper surface of the shell 21 and the front end surface 21121 of the shell 21 close to the pot surface space 111 are easily contaminated by urine when men urinate while standing. Since there are no openings in these two areas, the dirt in these two areas can be rinsed clean by rinsing with a rag or water, and there will be no dirt accumulating in the openings and making it difficult to clean.

[0076] In an illustrative embodiment, Figure 6 、 7 As shown, the housing 21 is provided with a protrusion 2122 that extends into the pot surface space 111 of the base 1. The protrusion 2122 is located at the bottom of one end of the housing 21 near the pot surface space 111 and protrudes into the pot surface space 111. The protrusion 2122 includes a lower surface 21220 exposed in the pot surface space 111. The lower surface 21220 of the protrusion 2122 is flat. The lower surface 21220 of the protrusion 2122 is provided with a protrusion opening 21231. The shape of the protrusion opening 21231 is not limited, and the protrusion opening 21231 can be a rectangular opening or a circular opening.

[0077] like Figure 3 As shown, the toilet lid device 2 further includes a movable module 24. The movable module 24 is disposed within the mounting cavity 210 of the housing 21. The movable module 24 is disposed at one end of the mounting cavity 210 adjacent to the pot surface space 111. The movable module 24 is configured to both extend from the mounting cavity 210 through the protrusion opening 21231 of the protrusion and to retract into the mounting cavity 210 through the protrusion opening 21231 of the protrusion.

[0078] The lower surface 21220 of the toilet lid device 2 exposed in the pot surface space 111 in the related art is typically uneven. When excrement falls into the water in the pot surface space 111, some of it may splash onto the lower surface 21220. Excrement splashing during washing may also contaminate the lower surface 21220. Due to the unevenness of the lower surface 21220, there are always corners that are difficult to clean with a brush. In contrast, the lower surface 21220 of the protrusion 2122 of the toilet lid device 2 exposed in the pot surface space 111 in the embodiment of the present application is flat, leaving no blind spots, making it easy to clean and improving the user experience. Furthermore, the extension 21231 is provided on the lower surface 21220 of the protrusion 2122, preventing it from being directly splashed by urine when a man urinates while standing.

[0079] In an illustrative embodiment, multiple movable modules 24 and extension ports 21231 are provided. Multiple movable modules 24 can extend from and retract into the installation cavity 210 from the multiple extension ports 21231, respectively. The lower surface 21220 includes an opening surface 2123. The opening surface 2123 is a plane facing the front and lower part of the shell 21. All extension ports 21231 are provided on the opening surface 2123. The opening surface 2123 is an inclined surface and faces the front and lower part of the shell 21. The opening surface 2123 is inclined downward toward the pot surface space 111. The movable module 24 can extend from the extension ports 21231 on the opening surface 2123 to below the excrement inlet 112 of the pot surface cavity 11 to clean or dry the human body.

[0080] The opening surface 2123 is constructed as a downwardly inclined plane, which has no blind spots for cleaning and is easy to clean. At the same time, it is also beneficial for the droplets splashed onto the opening surface 2123 to slide down.

[0081] In an illustrative embodiment, Figure 8 、 9 As shown, the multiple movable modules 24 include a washing module 241 and a drying module 242. The washing module 241 is provided with a spray rod 2411. The spray rod 2411 can spray water to wash the human body. The drying module 242 is provided with a drying channel 2421. The drying channel 2421 can deliver hot air to dry the human body. The multiple extension ports 21231 on the protrusion 2122 include a washing extension port 21232 and a drying extension port 21233. The washing extension port 21232 and the drying extension port 21233 can be set at the same horizontal height and separated. The spray rod 2411 of the washing module 241 can extend from the washing extension port 21232 or retract into the installation cavity 210. The drying channel 2421 of the drying module 242 can extend from the drying extension port 21233 or retract into the installation cavity 210.

[0082] In an illustrative embodiment, Figure 6 、 7 As shown, the lower surface 21220 of the protrusion 2122 further includes a lower end surface 2124 and two side surfaces 2125. The lower end surface 2124 of the protrusion 2122 faces downward from the protrusion 2122 and is connected to the bottom edge of the opening surface 2123. The two side surfaces 2125 of the protrusion 2122 are respectively connected to opposite sides of the lower end surface 2124, and the two side surfaces 2125 of the protrusion 2122 are also respectively connected to opposite sides of the opening surface 2123. The lower end surface 2124 can be a plane. The side surfaces 2125 can be plane or curved. The transition between the lower end surface 2124 and the two side surfaces 2125 is smooth. The lower end surface 2124 and the opening surface 2123 can form an obtuse angle. The opening surface 2123 and the side surfaces 2125 can also form an obtuse angle.

[0083] In this way, the lower end surface 2124 and the two side surfaces 2125 are flat, and there is a smooth transition between the lower end surface 2124 and the two side surfaces 2125, without any blind spots for cleaning, making cleaning easier.

[0084] In an illustrative embodiment, Figure 6 、 7 As shown, the toilet lid device 2 also includes a brush ring nozzle module 25. The brush ring nozzle module 25 is disposed within the mounting cavity 210 of the housing 21 and includes a brush ring nozzle 251 and a drive mechanism. The drive mechanism can be a motor. The brush ring nozzle 251 is configured to rotate relative to the housing 21. The brush ring nozzle 251 can be configured in an L-shape. The drive mechanism is connected to the brush ring nozzle 251 and is used to drive the brush ring nozzle 251 to rotate.

[0085] The lower end surface 2124 of the protrusion 2122 is further provided with an inlet and outlet 21241. The inlet and outlet 21241 communicates with the mounting cavity 210. The drive mechanism is configured to both drive the brush ring nozzle 251 to rotate until it extends out of the housing 21 through the inlet and outlet 21241 of the protrusion 2122, and to drive the brush ring nozzle 251 to rotate until it fully enters the housing 21 through the inlet and outlet 21241.

[0086] After the brush ring nozzle 251 of the brush ring nozzle assembly 25 rotates to extend out of the shell 21, it can spray water toward the inner wall of the pot surface cavity 11 to flush the inner wall of the pot surface cavity 11 and form a water seal in the pot surface space 111.

[0087] In this way, the brush ring nozzle assembly 25 is arranged on the toilet cover device 2 instead of on the pot surface cavity 11 of the seat body 1, so there is no need to open the installation hole of the brush ring nozzle assembly 25 on the pot surface cavity 11 of the seat body 1, which reduces the cleaning dead corners of the inner wall of the pot surface cavity 11 and makes the inner wall of the pot surface cavity 11 easier to clean.

[0088] In an illustrative embodiment, Figure 3 As shown, the toilet cover device 2 further includes a water inlet assembly 27 , a brush ring water supply pipe 26 and a flushing water supply pipe. The water inlet assembly 27 is arranged in the installation cavity 210 of the housing 21 .

[0089] The water inlet assembly 27 is provided with a water inlet 271. The water inlet 271 can be an opening extending out of the housing 21 from the bottom wall of the housing 21. The water inlet 271 is used to connect with a tap water supply pipe, which can transport water to the water inlet pipe, or to connect with a pipe where the water in the toilet's built-in water tank is pressurized by a booster pump. The water inlet assembly 27 is also provided with a first water outlet and a second water outlet. A waterway is provided inside the water inlet assembly 27, which connects the water inlet 271 with the first water outlet and the second water outlet, respectively. The water input into the water inlet assembly 27 through the water inlet 271 can be output from the water inlet assembly 27 through the first water outlet and the second water outlet. The first water outlet can be connected to the brush ring nozzle module 25 through the brush ring water supply pipe 26, and the water inlet assembly 27 can supply water to the brush ring nozzle assembly 25 through the brush ring water supply pipe 26. The second water outlet can be connected to the flushing module 241 through a flushing water supply pipe, and the water inlet assembly 27 can supply water to the flushing module 241 through the flushing water supply pipe.

[0090] A filter can also be installed within the water inlet assembly 27. This filter is located in the waterway between the water inlet 271 and the first water outlet, and is used to filter the water delivered to the brush ring nozzle assembly 25. A filter element can also be installed within the water inlet assembly 27. This filter element is located in the waterway between the water inlet 271 and the second water outlet, and is used to filter the water delivered to the flushing module 241. The flushing module 241 uses filtered water to flush the body, which is healthier.

[0091] A flush valve may also be provided in the water inlet assembly 27. The flush valve is provided on the water path between the water inlet 271 and the first water outlet, and is used to control the opening and closing of the water outlet of the brush ring nozzle assembly 25.

[0092] In this way, the water inlet assembly 27, the brush ring water supply pipe 26, and the flushing water supply pipe are centrally arranged in the housing 21, making the structure of the toilet cover device 2 more compact, the modularity of the toilet 100 higher, and the installation of the toilet 100 more convenient. At the same time, the water inlet assembly 27, the brush ring water supply pipe 26, and the flushing water supply pipe are not exposed in the seat body 1, which is more neat and beautiful.

[0093] In an illustrative embodiment, Figure 8 As shown, the housing 21 includes a bottom shell 212 and a top cover 211. The bottom shell 212 is provided with a receiving groove, the opening of which is provided at the top of the bottom shell 212. The protrusion 2122 is a part of the bottom shell 212, and the protrusion 2122 is provided at the front end of the bottom shell 212.

[0094] The top cover 211 comprises a cover body 2111 and a baffle 2112. The cover body 2111 covers the top of the bottom shell 212 and covers the opening of the accommodating groove of the bottom shell 212. The cover body 2111 and the bottom shell 212 enclose the mounting cavity 210. The baffle 2112 can be configured as a flat plate. The baffle 2112 extends downward from the front end of the cover body 2111. The baffle 2112 and the cover body 2111 can be an integrally formed structure. There is no gap between the baffle 2112 and the cover body 2111. No opening is provided on the baffle 2112. The surface of the baffle 2112 facing forward is the front end surface 21121 of the one end of the shell 21 close to the urinal space 111. The baffle 2112 covers the end surface of the protruding portion 2122 facing forward, and the lower edge of the baffle 2112 is lower than the lower edge of the end surface of the protruding portion 2122 facing forward. The lower edge of the baffle 2112 is also lower than the upper edge of the opening surface 2123.

[0095] In this way, the baffle 2112 can shield the protruding portion 2122, so as to avoid that the urine of the male urination directly falls on the protruding portion 2122 and directly enters the outlet 21231 of the protruding portion 2122. Since the lower edge of the baffle 2112 is lower than the lower edge of the end surface of the protruding portion 2122 facing forward, and the lower edge of the baffle 2112 is also lower than the upper edge of the opening surface 2123, the urine on the baffle 2112 will not flow along the surface of the baffle 2112 to the protruding portion 2122, but directly drip into the urinal space 111. In particular, the surface of the baffle 2112 is not provided with any opening, and the surface of the baffle 2112 is flat, without cleaning dead angle, and is easy to clean.

[0096] In an exemplary embodiment, the angle between the line connecting the lower edge of the outlet 21231 and the lower edge of the baffle 2112 and the horizontal plane is less than or equal to 45° in the same vertical plane. The angle is preferably less than 30°.

[0097] When the movable module 24 is completely retracted into the mounting cavity 210 of the shell 21, neither the movable module 24 nor the outlet 21231 can be observed by the user, and the user can only see the flat baffle 2112, which is more beautiful in appearance, and can further avoid that the urine of the male urination splashes into the outlet 21231.

[0098] In an exemplary embodiment, as shown in Figures 10-13 The closestool 100 further comprises a connecting assembly 3. The connecting assembly 3 comprises the connecting module 21 and a lifting module 32. The connecting module 21 comprises a positioning guide column 311. The positioning guide column 311 is connected to the top rear side of the seat body 1 and extends vertically.

[0099] The bottom wall of the housing 21 is provided with a fixing hole 2121. The fixing hole 2121 can be a through hole. The outer diameter of the positioning guide post 311 is smaller than the inner diameter of the fixing hole 2121. The positioning guide post 311 and the fixing hole 2121 of the housing 21 are clearance-fitted.

[0100] The lifting module 32 is disposed on a side of the connecting module 21 close to the pot surface space 111. The lifting module is configured to lift and lower an end of the housing 21 close to the pot surface space 111.

[0101] In this way, when the gap between the front end of the shell 21 and the base 1 needs to be cleaned, the lifting module only needs to lift the end of the shell 21 near the pot surface space 111 to open the gap, making it easier for the user to clean the stains in the gap. After cleaning the gap, the lifting module lowers the height of the end of the shell 21 near the pot surface space 111 until the shell 21 is re-covered on the base 1. During this process, the positioning guide post 311 abuts the shell 21, preventing it from moving forward or backward to the base 1.

[0102] In one exemplary embodiment, the top wall of the housing 21 is provided with a first through hole 21111. The first through hole 21111 may be provided on the cover 2111. The bottom wall of the housing 21 is provided with a second through hole 2120. The second through hole 2120 may be provided on the bottom shell 212. The first through hole 21111 and the second through hole 2120 are both circular holes, and are coaxially arranged between the first through hole 21111 and the second through hole 2120.

[0103] The base 1 is provided with a connecting portion 12. The connecting portion 12 may be provided on the inner wall of the base 1. The connecting portion 12 is provided with a mounting hole 121. The mounting hole 121 vertically passes through the connecting portion 12. The mounting hole 121 is located below the second through hole 2120 of the housing 21.

[0104] The lifting module 32 includes a support rod 321, a knob 322, a stopper 323, and a support member 324. The support rod 321 can be configured as a straight rod with a circular cross-section. The support rod 321 has a downwardly facing bottom end with external threads. The support rod 321 extends through the first through-hole 21111 and the second through-hole 2120 in the housing 21.

[0105] The knob 322 is disposed at the top of the support rod 321. The knob 322 is fixedly connected to the support rod 321. The limiter 323 is disposed on the support rod 321. The limiter 323 can be a retaining spring. The limiter 323 abuts against the bottom surface of the housing 21.

[0106] The support member 324 can be configured as a rotating body. The support member 324 is provided with a third through hole 3240 and an annular groove 3244. The third through hole 3240 extends through the support member 324. The annular groove 3244 is located on the side wall of the support member 324. The annular groove 3244 is coaxial with the third through hole 3240. The third through hole 3240 is sleeved on the support rod 321. The third through hole 3240 is also provided with an internal thread, which is screwed onto the external thread of the support rod 321.

[0107] The support member 324 passes through the mounting hole 121 of the connecting portion 12. The connecting portion 12 is clamped in the annular groove 3244 of the support member 324 and cannot be separated from the annular groove 3244. The connecting portion 12 and the support member 324 have a loose fit. The connecting portion 12 and the support member 324 can be connected by a positive connection, so that the support member 324 cannot rotate relative to the connecting portion 12 in the circumferential direction of the support member 324. The connecting portion 12 supports the support member 324.

[0108] In this way, if the user rotates the knob 322 in one direction, for example, clockwise, the knob 322 causes the support rod 321 to rotate. As the support rod 321 rotates, it rises relative to the support member 324. As the support rod 321 rises, the stopper 323 causes the housing 21 to rise synchronously. If the user rotates the knob 322 in the other direction, the knob 322 causes the support rod 321 to rotate. As the support rod 321 rotates, it descends relative to the support member 324. As the support rod 321 descends, the stopper 323 descends synchronously, and the housing 21 descends under the action of gravity. This structure of the lifting module 32 is simple and compact, taking up little space.

[0109] In an illustrative embodiment, Figure 11 、 13 As shown, the support member 324 includes a fixing nut 3241 and a fixing plate 3242. The fixing nut 3241 includes a barrel 32411 and a first limiting portion 32412. The barrel 32411 can be configured as a cylinder. The barrel 32411 is provided with a screw hole. The screw hole can vertically penetrate the barrel 32411. The first limiting portion 32412 extends radially outward from one end of the barrel 32411. The first limiting portion 32412 can be configured as a circular ring.

[0110] The fixing plate 3242 is connected to the end of the fixing nut 3241 facing away from the first limiting portion 32412. The fixing plate 3242 may be disc-shaped. The outer diameter of the fixing plate 3242 may be the same as the outer diameter of the first limiting portion 32412, and both may be larger than the inner diameter of the mounting through hole 121 of the connecting portion 12. A fourth through hole 32421 is provided on the fixing plate 3242. The fourth through hole 32421 is coaxial with the screw hole 32413 of the cylinder 32411. The fourth through hole 32421 and the screw hole 32413 constitute the third through hole 3240 on the support member 324. The fixing plate 3242, the cylinder 32411 and the first limiting portion 32412 enclose an annular groove 3244 of the support member 324.

[0111] The screw hole 32413 of the cylinder 32411 and the fourth through hole 32421 of the fixing plate 3242 are both sleeved on the support rod 321 , and the fixing nut 3241 and the support rod 321 are threadedly connected.

[0112] The support member 324 is provided in a split type, which makes it easier to install on the connecting portion 12.

[0113] In an illustrative embodiment, Figure 4 As shown, the toilet cover device 2 further includes a decorative cover 20. The decorative cover 20 is constructed as a generally plate-shaped structure. The decorative cover 20 covers the top of the housing 21. The decorative cover 20 and the housing 21 are detachably connected. The decorative cover 20 at least covers the knob 322.

[0114] In this way, when the decorative cover 20 is covered on the top of the housing 21, the knob 322 and other components will not be exposed to the outside, which is more beautiful. The upper surface of the decorative cover 20 is flat and easy to clean.
