Description

Technical Field

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

[0002] Existing smart toilets typically have a brush nozzle mounted on the pot surface cavity of the toilet seat. The pot surface cavity contains a pot surface space, and the brush nozzle is typically mounted on the top wall of the pot surface space. The brush nozzle sprays brush water onto the inner wall of the pot surface space, which can flush away dirt adhering to the inner wall of the pot surface space.

[0003] However, because the pot surface cavity of the base body requires a mounting hole for the brush ring nozzle, dirt easily accumulates in the gap between the mounting hole and the brush ring nozzle, and this dirt is difficult to clean, resulting in local mold and discoloration on the pot surface cavity. Furthermore, installing the brush ring nozzle in the pot surface cavity makes toilet plumbing connections more complicated. Summary of the Invention

[0004] The present invention provides a toilet cover device, which includes:

[0005] The housing comprises a bottom shell for being mounted on the top of the toilet seat, wherein the front side of the bottom shell is provided with a brush ring mounting chamber and a receiving groove located in front of the brush ring mounting chamber;

[0006] a brush ring nozzle module, at least a portion of which is disposed in the brush ring installation chamber, comprising a rotatable brush ring nozzle, wherein the brush ring nozzle can be rotated to a hidden position for storage in the storage slot;

[0007] A brush ring water supply pipe, one end of which is connected to the brush ring nozzle module;

[0008] a water inlet assembly, mounted on the rear side of the bottom shell, provided with a water inlet and a first water outlet connected to the water inlet, wherein the first water outlet is connected to an end of the brush ring water supply pipe away from the brush ring nozzle module;

[0009] Wherein, the water inlet assembly is used to supply water to the brush ring nozzle module through the brush ring water supply pipe so that the brush ring nozzle sprays water into the pot surface space of the seat body.

[0010] The present application also proposes a toilet comprising:

[0011] The base body is provided with a pot surface cavity therein, and the pot surface space is provided in the pot surface cavity; and

[0012] A toilet lid device as described above;

[0013] Wherein, the toilet cover device is arranged on the top of the seat body.

[0014] The beneficial effects of this application are:

[0015] The brush ring nozzle module of the toilet lid assembly can deliver water toward the pot surface space of the seat, thereby flushing the inner wall of the pot surface space. Because the brush ring nozzle module is installed in the toilet lid assembly, there is no need to install a brush ring nozzle module separately on the seat. This eliminates the need for a brush ring opening or a mounting opening for the brush ring nozzle module on the inner wall of the pot surface space of the seat. The inner wall of the pot surface space of the seat can be smoother, less prone to dirt accumulation, and easier to clean. Furthermore, because the brush ring water supply pipe and the brush ring nozzle module are both installed on the bottom shell, the integration is higher. Only the water supply pipe needs to be connected to the water inlet of the water inlet assembly. Since the water inlet assembly is located on the rear side of the bottom shell, connecting the pipes is more convenient.

[0016] Other features and advantages of the present application will be described in the following description, and in part will become apparent from the description, or will be understood by practicing the present application. Other advantages of the present application can be realized and obtained by the solutions described in the description and the drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0073] 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.

[0074] 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.

[0075] like Figure 1 、 2As shown in Figures 15 and 48, the toilet cover device 2 includes a shell 21, a seat ring 22, a toilet cover 23, a brush ring nozzle module 25, a brush ring water supply pipe 26, and a seal 28. The shell 21 is arranged on the top of the toilet cover 23 and is located on the rear side of the pot surface cavity 11. The shell 21 can be a thin shell structure. The shell 21 includes a bottom shell 212. The bottom shell 212 of the shell 21 is connected to the top of the seat body 1. The front side of the bottom shell 212 is provided with a brush ring installation chamber 204 and a storage groove 2126 located on the front side of the brush ring installation chamber 204.

[0076] like Figure 8 、 11 As shown in Figures 48, the brush ring nozzle module 25 is installed on the front side of the bottom shell 212. The front side of the bottom shell 212 is the side of the bottom shell 212 close to the pot surface space. The brush ring nozzle module 25 includes a brush ring nozzle 251 and a base 252. The base 252 can be a shell-shaped structure. The base 252 is connected to the shell 21. The base 252 can be arranged on the side of the shell 21 close to the pot surface cavity 11. The base 252 and the shell 21 can be screwed or snap-connected. The brush ring nozzle 251 is arranged on the base 252, and the brush ring nozzle 251 can extend from the base 252. A water outlet is provided at one end of the brush ring nozzle 251 away from the base 252, and a water spray port is provided at one end of the brush ring nozzle 251 close to the base 252. The water spray port is configured to spray water toward the pot surface space 111 of the base 1, and the sprayed water can be tap water. At least a portion of the brush ring nozzle module 25 is disposed in the brush ring installation chamber 204 , for example, the base 252 is disposed in the brush ring installation chamber 204 . The brush ring nozzle 251 can be rotated to a hidden position stored in the storage groove 2126 .

[0077] The water inlet assembly 27 is installed on the rear side of the bottom shell 212. The rear side of the bottom shell 212 is the side of the bottom shell 212 away from the pot surface space 111. The water inlet assembly 27 is provided with a water inlet 271. The water inlet 271 can be an opening on the bottom wall of the bottom shell 212 extending to the bottom of the bottom shell 212. The water inlet 271 is used to connect with the tap water supply pipe, and the tap water supply pipe can transport water to the water inlet of the water inlet assembly 27. The water inlet assembly 27 is also provided with a first water outlet. A water channel is provided in the water inlet assembly 27, which connects the water inlet 271 with the first water outlet respectively. The water input into the water inlet assembly 27 by the water inlet 271 can be output from the water inlet assembly 27 through the first water outlet. The opposite ends of the brush ring water supply pipe 26 are respectively connected to the first water outlet of the water inlet assembly 27 and the brush ring nozzle module 25. The first water outlet of the water inlet assembly 27 is connected to the brush ring nozzle module 25 through the brush ring water supply pipe 26. The water inlet assembly 27 can supply water to the brush ring nozzle module 25 through the brush ring water supply pipe 26. After receiving the water input by the brush ring water supply pipe 26, the brush ring nozzle module 25 sprays water into the pot surface space 111 of the base body.

[0078] In this way, the brush ring nozzle module 25 of the toilet lid device 2 can deliver brush ring water toward the pot surface space 111 of the seat body 1, thereby flushing the inner wall of the pot surface space 111. Because the brush ring nozzle module 25 is installed in the toilet lid device 2, there is no need to install a brush ring nozzle module 25 separately on the seat body 1. This can eliminate the need for a brush ring opening or a mounting opening for the brush ring nozzle module 25 on the inner wall of the pot surface space 111 of the seat body 1. The inner wall of the pot surface space 111 of the seat body 1 can be smoother, less prone to dirt accumulation, and easier to clean. At the same time, because the brush ring water supply pipe and the brush ring nozzle module 25 are both installed on the bottom shell 212, the integration is higher. Only the water supply pipe needs to be connected to the water inlet of the water inlet assembly 27. Since the water inlet assembly 27 is located on the rear side of the bottom shell 212, it is more convenient to connect the pipes.

[0079] The brush ring nozzle 251 of the brush ring nozzle module 25 rotates to a hidden position when flushing is not required, allowing the brush ring nozzle 251 to be hidden within the storage groove 2126 of the housing 21. With the brush ring nozzle 251 hidden, urine or splashed sewage is unlikely to enter the water outlet of the brush ring nozzle 251, thereby preventing contamination of the internal passage of the brush ring nozzle 251. Furthermore, the hidden brush ring nozzle 251 enhances the appearance of the brush ring nozzle 251.

[0080] In an illustrative embodiment, Figure 6 、 46 As shown in Figures 48 to 50, the bottom shell 212 is provided with a downwardly recessed receiving tank 2127. The opening of the receiving tank 2127 faces upward. The receiving tank 2127 includes a first tank 201, a second tank 202, and a third tank 203. The first tank 201 is located at the rear of the bottom shell 212, while the second tank 202 and the third tank 203 are arranged side by side at the front of the bottom shell 212. The second tank 202 and the third tank 203 are both located on the front side of the first tank 201 and are connected to the first tank 201. The front side of the first tank 201 is the side of the first tank 201 that is closest to the pot surface space 111. The second tank 202 and the third tank 203 are separated in the left-right direction. There is a gap between the second tank 202 and the third tank 203. The inner cavities of the first tank 201, the second tank 202, and the third tank 203 can all be constructed in a cubic shape. The sidewall of the first tank body 201 near the second tank body 202, the sidewall of the second tank body 202 near the first tank body 201, and the sidewall of the first tank body 201 near the third tank body 203 and the second tank body 202 enclose a cavity, which serves as the brush ring installation chamber 204. The brush ring nozzle module 25 is at least partially disposed within the brush ring installation chamber 204. The water inlet assembly 27 is disposed within the first tank body 201.

[0081] In this way, the brush ring installation chamber 204 is arranged outside the containing groove 2127 of the bottom shell 212, and the brush ring nozzle module 25 is arranged in the brush ring installation chamber 204, so that water sprayed by the brush ring nozzle module 25 can be prevented from entering the containing groove 2127. Meanwhile, the brush ring nozzle module 25 can be hidden in the brush ring installation chamber 204 and is not easy to be bumped. In particular, the brush ring installation chamber 204 is arranged at the front side of the bottom shell 212, so that the brush ring nozzle module 25 can be arranged close to the pot face space 111 to facilitate water spraying into the pot face space 111.

[0082] In an exemplary embodiment, the water inlet assembly 27 is arranged at a side of the first groove 201 opposite to the second groove 202. The second groove 202 is provided with a first opening 2021 on the side wall close to the first groove 201. The first opening 2021 is a through hole penetrating the second groove 202. The first opening 2021 connects the inner cavity of the second groove 202 and the brush ring installation chamber 204. The brush ring water supply pipe 26 is connected to the water inlet assembly 27 at one end and connected to the brush ring nozzle module 25 at the other end, and sequentially passes through the first groove 201, the second groove 202, the first opening 2021 and the brush ring installation chamber 204.

[0083] In this way, the brush ring water supply pipe 26 is arranged, so that the length of the brush ring water supply pipe 26 can be as small as possible and the space in the shell 21 can be occupied as little as possible.

[0084] In an exemplary embodiment, as shown in Figure 48 , the bottom shell 212 further comprises a protruding portion 2122 arranged at a side of the brush ring installation chamber 204 away from the first groove 201. The protruding portion 2122 is connected to the side walls of the second groove 202 and the third groove 203 away from the first groove 201, and at least partially exposed to the pot face space 111 of the seat body. The protruding portion 2122 extends from the rear side of the pot face cavity 11 to the upper region of the pot face space 111. The protruding portion 2122 is located at the upper end of the rear portion of the pot face space 111. The bottom of the protruding portion 2122 is exposed in the pot face space 111.

[0085] As shown in Figure 9 , the receiving groove 2126 is arranged at the bottom of the protruding portion 2122. The receiving groove 2126 is connected to the brush ring installation chamber 204. The base is arranged in the brush ring installation chamber 204 of the bottom shell 212. The brush ring spray pipe 251 of the brush ring nozzle module 25 extends from the brush ring installation chamber 204 to the receiving groove 2126. The opening of the receiving groove 2126 comprises an inlet and outlet exposed to the pot face space 111. The brush ring spray pipe 251 is exposed to the pot face space 111 through the inlet and outlet. The inlet and outlet of the brush ring spray pipe 251 exposed to the pot face space 111 are exposed to the shell 21. The water outlet of the brush ring spray pipe 251 can spray water towards the pot face space 111.

[0086] In this way, the brush ring nozzle 251 can output brush ring water to the pot surface space 111 from the area where the protrusion 2122 of the shell 21 is exposed to the pot surface space 111, and the brush ring nozzle 251 can easily flush the brush ring water directly onto the inner wall of the pot surface space 111.

[0087] In an illustrative embodiment, Figure 8 As shown, the brush ring nozzle module 25 also includes a driving mechanism. The driving mechanism can be a motor. The brush ring nozzle 251 is rotatably connected to the base. The brush ring nozzle 251 is configured to be rotatable relative to the base 252. The brush ring nozzle 251 can be arranged in an "L" shape. The driving mechanism is arranged on the base 252. The driving mechanism is connected to the brush ring nozzle 251, and the driving mechanism is used to drive the brush ring nozzle 251 to rotate. The driving mechanism includes a transmission mechanism and a motor. The motor is connected to the brush ring nozzle 251 through a transmission mechanism, and the transmission mechanism can be a gear transmission mechanism. The torque output by the motor is transmitted to the brush ring nozzle 251 through the transmission mechanism, thereby driving the brush ring nozzle 251 to rotate.

[0088] The driving mechanism is configured to drive the brush ring nozzle 251 to rotate to a water spraying position extending out of the shell 21 through the inlet and outlet 21241 of the shell 21, and also to drive the brush ring nozzle 251 to rotate to a hidden position entering the shell 21 through the inlet and outlet 21241.

[0089] In this way, the brush ring nozzle 251 of the brush ring nozzle module 25 rotates to the water spraying position when flushing is required, so that the brush ring nozzle 251 extends out of the receiving groove 2126 of the shell 21 and then sprays water into the pot surface space 111.

[0090] In an illustrative embodiment, Figure 7 、 50 As shown, the area of ​​the shell 21 exposed to the pot surface space 111 includes a lower surface 21220 exposed in the pot surface space 111 by the protrusion 2122. The lower surface 21220 also includes a lower end surface 2124. The lower end surface 2124 is set downward. The lower end surface 2124 is connected to the lower edge of the opening surface 2123 and is located on the rear side of the opening surface 2123. The lower end surface 2124 is also located below the brush ring nozzle module 25. The lower end surface 2124 faces the bottom of the shell 21. The inlet and outlet 21241 are set on the lower end surface 2124. The brush ring nozzle 251 is exposed to the outer shell through the inlet and outlet 21241. When the brush ring nozzle 251 is in the hidden position, the surface of the brush ring nozzle module 25 exposed through the inlet and outlet 21241 is flush with or tangent to the lower end surface 2124. The surface of the brush ring nozzle module 25 exposed through the inlet and outlet 21241 includes the surface facing when the brush ring nozzle 251 is in the hidden position and the surface of the base 252 exposed in the area of ​​the pot surface space 111.

[0091] Thus, when the brush ring nozzle 251 is in the hidden position, the surface of the brush ring nozzle module 25 exposed through the inlet and outlet 21241 is flush with or tangent to the lower end surface 2124. The lower end surface 2124 and the surface of the brush ring nozzle 251 exposed through the inlet and outlet 21241 are connected to each other, making it easier to clean the stained area. At the same time, the brush ring nozzle module 25 can also prevent splashed dirt from entering the inlet and outlet 21241.

[0092] In an illustrative embodiment, Figure 9 、 48 As shown, the housing 21 also includes a cover 213. The cover 213 can be a right-angled curved plate with an L-shaped cross-section. The cover 213 covers the bottom end and the front end of the brush ring mounting chamber 204. The cover 213 is connected to the bottom shell 212. The cover 213 and the bottom shell 212 can be detachably connected. The cover 213 and the bottom shell 212 can be screwed together.

[0093] The blocking cover 213 can shield the brush ring nozzle module 25 and the brush ring water supply pipe 26 in the brush ring installation chamber 204 , thereby providing protection for the brush ring nozzle module 25 and the brush ring water supply pipe 26 .

[0094] In an exemplary embodiment, the water inlet assembly 27 is further provided with a second water outlet 272. The second water outlet 272 is connected to the water inlet of the water inlet assembly 27. Water input into the water inlet assembly 27 through the water inlet 271 can be output from the water inlet assembly 27 through the second water outlet 272.

[0095] like Figure 47 、 48 As shown, the toilet seat device further includes a movable module 24 and a water treatment assembly 30. The movable module 24 includes a flushing module 241 disposed above the brush ring mounting chamber 204. The flushing module 241 is used to flush the human body. The flushing module 241 can be disposed above the brush ring mounting chamber 204 and the brush ring nozzle module 25.

[0096] The water treatment assembly 30 is disposed within the first tank 201. It is connected to the second water outlet 272 of the water inlet assembly 27 via a pipe. The water treatment assembly 30 is also connected to the flushing module 241 via a pipe. The water treatment assembly 30 is used to pressurize and / or heat the water output from the second water outlet 272 of the water inlet assembly 27 before delivering it to the flushing module 241 for flushing the human body.

[0097] The water treatment module heats and pressurizes the water output by the water inlet assembly 27. The flushing module 241 then flushes the body with the pressurized and heated water, providing a more comfortable experience. Furthermore, positioning the water treatment module on one side of the water inlet assembly 27 shortens the piping between the two, saving space within the housing 21. Positioning the flushing module 241 above the brush ring mounting chamber 204 and the brush ring nozzle module 25 facilitates accurate flushing of the gluteal area without interfering with the brush ring nozzle. The flushing module 241 and the brush ring nozzle complement each other.

[0098] In an illustrative embodiment, the water treatment component 30 includes a water pump module 302 and a heating module 301. The heating module 301 can be arranged upstream of the water pump module 302 or downstream of the water pump module 302. The heating module 301 is used to convert electrical energy into heat to heat water. When the heating module 301 is arranged upstream of the water pump module 302, the heating module 301 first heats the water output from the second water outlet 272 of the water inlet component 27, and then the water pump module 302 pressurizes the hot water and pumps the hot water to the flushing module 241. When the heating module 301 is arranged downstream of the water pump module 302, the water pump module 302 first pressurizes the cold water output from the second water outlet 272 of the water inlet component 27, and the pressurized water is transported to the heating module 301. The heating module 301 then heats the pressurized water, and the heated water is transported to the flushing module 241.

[0099] In an exemplary embodiment, the water inlet assembly 27 is disposed on the side of the first tank 201 adjacent to the second tank 202, the water pump module 302 is disposed on the side of the first tank 201 adjacent to the third tank 203, and the heating module 301 is disposed between the water pump module 302 and the water inlet assembly 27. The second water outlet 272 of the water inlet assembly 27 is connected to the heating module 301 via a pipe, and the heating module 301 is connected to the flushing module 241 via a pipe.

[0100] In this way, the water inlet assembly 27, the heating module 301 and the water pump module 302 are arranged in sequence in the first tank body 201. The pipes between the water inlet assembly 27 and the heating module 301, and the pipes between the heating module 301 and the water pump module 302 can be set very short, so that the space in the first tank body 201 can be fully utilized, and the structure of the toilet cover device is more compact.

[0101] In an illustrative embodiment, Figure 15As shown, the toilet lid device also includes a main control board module 32. The main control board module 32 includes a protective box and a main control board. The main control board is disposed within the protective box, which can be configured as a flat box-like structure. The main control board module 32 serves as the toilet's logic control unit. The main control board module 32 is electrically connected to all of the toilet's actuators, which may include the active module 24, the heating module 301, the water pump module 302, the water inlet assembly 27, and the brush ring nozzle module 25. The main control board module 32 is disposed above the water treatment assembly 30.

[0102] In this way, since the heating module 301 and the water pump module 302 in the water treatment component 30 are arranged in sequence along the horizontal direction, the height of the water treatment component 30 is small, and the main control board module 32 is set above the water treatment component 30, the empty space above the water treatment component 30 can be fully utilized, making the toilet cover device more compact.

[0103] In an illustrative embodiment, Figure 15 As shown, there are multiple movable modules 24, and the multiple movable modules 24 also include a drying module 242 for drying moisture on the surface of the human body. The drying module 242 is arranged on the side of the flushing module 241 close to the third trough body 203, and the lower part of the drying module 242 extends into the third trough body 203.

[0104] The drying module 242 outputs a hot air flow to dry the buttocks area. The drying module 242 is relatively large in height. It is located on the side of the washing module 241 near the third tank 203 and extends into the third tank 203, making full use of the space within the third tank 203.

[0105] In an illustrative embodiment, Figure 3 、 6 As shown in Figures 7 and 8, a mounting cavity 210 is provided in the housing 21. The housing 21 is also provided with an extension opening 21231. The extension opening 21231 is provided on a side of the housing 21 near the pot surface space 111. The extension opening 21231 is connected to the mounting cavity 210. The seat ring 22 and the toilet lid 23 are both rotatably connected to the housing 21.

[0106] like Figure 9 、 10As shown, the movable module 24 is arranged at one end of the installation cavity 210 near the extension port 21231. The movable module 24 includes a main body 2401 and a movable part 2402. The main body 2401 is arranged in the installation cavity 210 of the shell 21. The main body 2401 is connected to the shell 21. The movable part 2402 can be constructed as a strip structure. The movable part 2402 and the main body 2401 can be connected by sliding. For example, a slide is provided on the main body 2401, and one end of the movable part 2402 is provided in the slide and can slide along the slide. The sliding direction of the movable part 2402 is the same as the extension direction of the movable part 2402. The movable part 2402 is passed through the extension port 21231. The movable part 2402 of the movable module 24 is configured to be able to extend out of the installation cavity 210 through the extension port 21231 and to be able to retract into the installation cavity 210 through the extension port 21231. The movable portion 2402 of the movable module 24 can extend out of the mounting cavity 210 to reach an operating position, and can also retract into the mounting cavity 210 to reach a stowed position. When the movable portion 2402 is in the stowed position, the end surface of the movable portion 2402 facing out of the mounting cavity 210 is flush with the outer surface of the housing 21. The end surface of the movable portion 2402 facing out of the mounting cavity 210 does not have an opening; the end surface of the movable portion 2402 facing out of the mounting cavity 210 can be flat.

[0107] The seal 28 has an annular structure. The seal 28 can be an O-ring, a rectangular seal, a U-ring, a V-ring or a Y-ring. The seal 28 is elastic. The material of the seal 28 can be rubber or silicone. The rubber can be EPDM rubber, nitrile rubber or other rubber. The material of the seal 28 can preferably be rubber with good wear resistance. The seal 28 is connected to the movable part 2402 or the shell 21. The seal 28 can be sleeved on the movable part 2402 and fixedly connected to the movable part 2402. The seal 28 can also be arranged on the inner wall of the extension port 21231 of the shell 21, the outer edge of the seal 28 is against the inner wall of the extension port 21231, and the outer edge of the seal 28 is fixedly connected to the inner wall of the extension port 21231, and the movable part 2402 is passed through the seal 28. When the movable portion 2402 moves to the storage position, the seal 28 blocks the gap between the protruding opening 21231 and the movable portion 2402 , thereby sealing the gap.

[0108] Thus, when movable portion 2402 is in the stowed position, one end of movable portion 2402 is located within extension opening 21231 of housing 21. A gap exists between the outer wall of movable portion 2402 and the inner wall of extension opening 21231, and sealing member 28 is located within the gap, sealing the gap. Movable portion 2402 blocks most of extension opening 21231, while sealing member 28 blocks the gap between movable portion 2402 and sealing member 28. Together, movable portion 2402 and sealing member 28 seal extension opening 21231 on housing 21, completely preventing dirt such as urine from entering housing 21 through extension opening 21231.

[0109] In an illustrative embodiment, Figure 6 、 7 As shown, the extension opening 21231 is provided on the lower surface 21220 of the protruding portion 2122. The shape of the extension opening 21231 is not limited, and the extension opening 21231 can be a rectangular opening or a circular opening. The lower surface 21220 of the protruding portion 2122 is flat.

[0110] The lower surface of toilet lid devices exposed in the pot surface space 111 in related art is often uneven. When excrement falls into the water in the pot surface space 111, some may splash onto this lower surface. This unevenness makes some corners difficult to clean with a brush. In contrast, the lower surface 21220 of the protrusion 2122 of the toilet lid device 2 in the embodiment of the present application, exposed in the pot surface space 111, is smooth, leaving no blind spots and making it easy to clean, thus improving the user experience. Furthermore, the extension 21231 is located on the lower surface 21220 of the protrusion 2122, preventing it from being directly splashed by urine when a man urinates while standing.

[0111] In an illustrative embodiment, a plurality of movable modules 2424 and protruding openings 21231 are provided. The plurality of movable modules 2424 can extend from and retract into the installation cavity 210 from the plurality of protruding openings 21231, respectively. The area where the brush ring nozzle 251 is exposed from the shell 21 to the pot surface space 111 includes a lower surface 21220 of the protrusion 2122, and 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 the protruding openings 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 movable module 2424 can extend from the protruding openings 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.

[0112] 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.

[0113] In an illustrative embodiment, Figure 12 As shown, the brush ring nozzle module 25 is arranged on the rear side of the opening surface 2123.

[0114] The brush ring nozzle module 25 is arranged on the rear side of the opening surface 2123 and is located below the movable module 2424. It does not affect the movable module 2424. The brush ring nozzle module 25 charges and discharges by utilizing the space on the rear side of the opening surface 2123 and below the movable module 2424, making the toilet cover device 2 more compact as a whole.

[0115] In an illustrative embodiment, Figure 6 As shown, the area of ​​the housing 21 exposed to the pot surface space 111 is provided with an inlet and outlet 21241. The inlet and outlet 21241 can be provided on the lower surface 21220 of the protrusion 2122.

[0116] In an illustrative embodiment, Figure 9 As shown, the lower end surface 2124 is recessed to form a receiving groove 2126, and the inlet and outlet 21241 is a downward opening of the receiving groove 2126. When the brush ring nozzle 251 is in the hidden position, it is stored in the receiving groove 2126.

[0117] In this way, when the brush ring nozzle 251 is stored in the storage groove 2126, it can greatly reduce the splashing of sewage and other pollutants to the water outlet of the brush ring nozzle 251 during human defecation or urination. At the same time, it can also prevent the water flushed by the flushing module 241 from splashing to the water outlet of the brush ring nozzle 251, thereby preventing the pipes inside the brush ring nozzle 251 from being contaminated.

[0118] In an illustrative embodiment, Figure 8 As shown, the brush ring nozzle 251 includes a first tube body 2511 and a second tube body 2512. The first tube body 2511 and the second tube body 2512 are both straight tubes. The first tube body 2511 and the second tube body 2512 are connected to each other. The first tube body 2511 is rotatably connected to the base 252. The first tube body 2511 can be arranged horizontally. One end of the first tube body 2511 extends from the base 252 to the side close to the pot surface space 111, and the second tube body 2512 extends from this end of the first tube body 2511 along the radial direction of the first tube body 2511. The first tube body 2511 and the second tube body 2512 are perpendicular to each other. The brush ring nozzle 251 rotates around the axis of the first tube body 2511.

[0119] The receiving groove 2126 includes a first groove 21261 and a second groove 21262. The first groove 21261 and the second groove 21262 are connected to each other. The first groove 21261 is located on the rear side of the lower end surface 2124 of the protrusion 2122. The second groove 21262 is located in front of the first groove 21261 and extends from the front end of the first groove 21261 to the side of the housing 21. The length of the second groove 21262 can be slightly longer than the length of the first tube 2511.

[0120] The first groove 21261 is used to accommodate at least a portion of the first tube 2511 and at least a portion of the base 252. When the brush ring nozzle 251 is in the hidden position, the second tube 2512 extends horizontally and is accommodated in the second groove 21262.

[0121] Therefore, the shape of the storage groove 2126 matches that of the brush ring nozzle 251 when it is in the hidden position, and can just accommodate the portion of the brush ring nozzle 251 and the base 252 exposed in the pot surface space 111.

[0122] In an illustrative embodiment, Figure 8 、 9 As shown, two brush ring nozzles 251 are provided, and the first tubes 2511 of the two brush ring nozzles 251 are parallel to each other. The second tubes 2512 of the two brush ring nozzles 251 extend in directions away from each other when in the hidden position. Two second grooves 21262 are provided, and the two second grooves 21262 extend from the front end of the first groove 21261 to opposite sides of the housing 21, respectively, and the two second grooves 21262 respectively accommodate the two first tubes 2511.

[0123] The drive mechanism can drive the two brush ring nozzles 251 to rotate synchronously, thereby adjusting the water spraying direction of the two brush ring nozzles 251 to clean the inner wall of the pot surface space 111 from different angles, thereby improving the cleaning effect. For example, the two brush ring nozzles 251 can spray water toward opposite sides of the pot surface space 111, or both brush ring nozzles 251 can spray water downward.

[0124] In an exemplary embodiment, the thickness of the rear wall 21260 of the second groove 21262 is less than 6 mm.

[0125] The thickness of the rear wall 21260 of the second groove 21262 is less than 6 mm, so that the flushing ports of the two brush ring nozzles 251 can be as close to the inner wall of the pot surface space 111 as possible, avoiding splashing when the brush ring nozzles 251 spray water onto the inner wall of the pot surface space 111.

[0126] In an exemplary embodiment, the outer surface of the rear wall 21260 of the second groove 21262 abuts against the inner side of the pot surface space 111. In this embodiment, the outer surface of the rear wall 21260 of the second groove 21262 is the rear side of the protrusion 2122.

[0127] The outer surface of the rear wall 21260 of the second groove 21262 abuts against the inner side surface of the pot surface space 111 to achieve positioning between the shell 21 and the base 1, making it more convenient to assemble the shell 21 on the base 1.

[0128] In an exemplary embodiment, the brush ring nozzle module 25 is centrally arranged at the upper portion of the rear end of the pot surface space 111. The brush ring nozzle module 25 is centrally arranged and can evenly flush the opposite sides of the pot surface space 111.

[0129] In an illustrative embodiment, Figure 13 As shown, when the brush ring nozzle 251 of the brush ring nozzle module 25 is in the hidden position, the height difference d between the lower surface of the brush ring nozzle 251 and the lowest point of the top of the pot surface cavity 11 is greater than or equal to 5 mm.

[0130] When the height difference d between the lower surface of the brush ring nozzle 251 and the lowest point of the top of the pot surface cavity 11 is greater than or equal to 5 mm, the brush ring water sprayed by the brush ring nozzle 251 of the brush ring nozzle module 25 will not leak out from the edge of the top of the pot surface cavity 11, thereby preventing the brush ring from drifting.

[0131] In an illustrative embodiment, Figure 6 、 7 As shown, the lower surface 21220 of the protrusion 2122 also includes 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. There is a smooth transition between the lower end surface 2124 and the two side surfaces 2125. There can be an obtuse angle between the lower end surface 2124 and the opening surface 2123. There can be an obtuse angle between the opening surface 2123 and the side surfaces 2125.

[0132] 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.

[0133] In one exemplary embodiment, a filter can also be provided within the water inlet assembly 27. The filter, located in the waterway between the water inlet 271 and the first water outlet, is used to filter water delivered to the brush ring nozzle module 25. A filter element can also be provided within the water inlet assembly 27. The filter element is located in the waterway between the water inlet 271 and the second water outlet 272, and is used to filter water delivered to the flushing module 241. The flushing module 241 uses filtered water to flush the human body, which is healthier.

[0134] A flush valve may also be provided in the water inlet assembly 27. The flush valve is provided in the water path between the water inlet 271 and the first water outlet, and is used to control the start and stop of the water outlet of the brush ring nozzle module 25.

[0135] 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.

[0136] In an illustrative embodiment, Figure 9 、 15 As shown, a fixing groove 21232 is further provided on the opening surface 2123. The toilet cover device also includes a night light assembly 33 arranged in the fixing groove 21232.

[0137] The night light component 33 can be an LED lamp. The night light component 33 emits light toward the pot surface space 111. The night light component 33 can illuminate the pot surface space 111 of the toilet. In the scenario of no light on at night, the user can also know the location of the toilet, thereby improving the user experience.

[0138] In an illustrative embodiment, Figure 49 As shown, the protrusion 2122 further includes a front end surface 2128 facing forward. The opening surface 2123 is a plane extending from the front edge of the lower end surface 2124 to the lower edge of the front end surface 2128. The opening surface 2123 is a plane, with fewer blind spots for cleaning and easier cleaning.

[0139] like Figure 15 As shown, the housing 21 includes a top cover 211 . An opening for accommodating the groove 2127 is provided at the top of the bottom shell 212 .

[0140] The top cover 211 includes 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 body 2127 of the bottom shell 212. The cover body 2111 and the bottom shell 212 enclose the installation cavity 210. The baffle 2112 can be constructed 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 molded structure. There is no gap between the baffle 2112 and the cover body 2111. No opening is set on the baffle 2112. The front surface of the baffle 2112 is the end surface of the shell 21 close to the pot surface space 111. The baffle 2112 covers the front end surface 2128 of the protrusion 2122, and the lower edge of the baffle 2112 is lower than the lower edge of the front end surface 2128 of the protrusion 2122.

[0141] In this way, the baffle 2112 can shield the protrusion 2122, preventing urine from directly falling onto the protrusion 2122 and directly entering the extension opening 21231 of the protrusion 2122. Furthermore, because the lower edge of the baffle 2112 is lower than the lower edge of the forward end surface of the protrusion 2122, urine on the baffle 2112 does not flow along the surface of the baffle 2112 onto the protrusion 2122, but instead drips directly into the pot surface space 111. In particular, the surface of the baffle 2112 is free of any openings and is smooth, leaving no blind spots for cleaning and making it easy to clean.

[0142] In an exemplary embodiment, in the same vertical plane, the angle between the line connecting the lower edge of the extension opening 21231 and the lower edge of the baffle 2112 and the horizontal plane is less than or equal to 45°, and preferably less than 30°.

[0143] When the movable module 2424 is fully retracted into the installation cavity 210 of the shell 21, the movable module 2424 and the extension port 21231 will not be observed by the user. The user can only see the flat baffle 2112, which is more beautiful as a whole. At the same time, it can further prevent urine from spilling into the extension port 21231 when men urinate.

[0144] In an illustrative embodiment, Figures 42-45 As shown, the toilet 100 further includes a connecting assembly 3. The connecting assembly 3 includes a connecting module 31 and a lifting module 32. The connecting module 31 includes a positioning guide post 311. The positioning guide post 311 is connected to the rear side of the top of the seat body 1 and extends vertically.

[0145] 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.

[0146] The lifting module 32 is disposed on a side of the connecting module 31 close to the pot surface space 111. The lifting module 32 is configured to lift and lower an end of the housing 21 close to the pot surface space 111.

[0147] 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 32 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 32 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.

[0148] 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.

[0149] 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.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] 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.

[0154] 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.

[0155] In an illustrative embodiment, Figure 43 、 44 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.

[0156] 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.

[0157] 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.

[0158] The support member 324 is provided in a split type, which makes it easier to install on the connecting portion 12.

[0159] 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.

[0160] 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.

[0161] In one exemplary embodiment, the top of the base 1 is further provided with an installation opening 13. The installation opening 13 is located at the rear side of the pot surface cavity 11. The space within the base 1 outside the pot surface shell 21 is connected to the installation opening 13. The receiving groove 21272127 extends into the base 1 through the installation opening 13.

[0162] like Figure 11 、 12 As shown in Figures 14 and 15, the rear sidewall 114 of the pot surface cavity 11 extends between the protrusion 2122 and the receiving groove 2127 2127. The side of the protrusion 2122 near the receiving groove 2127 2127 abuts against the inner wall of the pot surface space 111 of the pot surface cavity 11. The width L between the receiving groove 2127 2127 and the protrusion 2122 is greater than the thickness of the rear sidewall 114 of the pot surface cavity 11. The width L between the receiving groove 2127 2127 and the protrusion 2122 can be greater than 13 mm.

[0163] In this way, since the rear side wall 114 of the pot surface cavity 11 extends between the protrusion 2122 and the accommodating groove body 21272127, and the width L between the accommodating groove body 21272127 and the protrusion 2122 is greater than the thickness of the rear side wall 114 of the pot surface cavity 11, the width L between the accommodating groove body 21272127 and the protrusion 2122 is preferably greater than 13 mm. When it is necessary to lift the shell 21 close to one end of the pot surface space 111 through the lifting module 32, the protrusion 2122 and the accommodating groove body 21272127 will not interfere with the shell 21, ensuring that the position of the shell 21 is adjustable.

[0164] In an illustrative embodiment, Figure 18 、 19As shown, the inner wall of the extension opening 21231 of the housing 21 is provided with a first sealing protrusion 24011. The first sealing protrusion 24011 protrudes radially inward on the inner wall of the extension opening 21231. The first sealing protrusion 24011 can be configured as an annular protrusion. The first sealing protrusion 24011 is located at the end of the extension opening 21231 of the housing 21 close to the mounting cavity 210. The movable part 2402 passes through the first sealing protrusion 24011, and the gap between the movable part 2402 and the first sealing protrusion 24011 is in clearance fit.

[0165] The sealing member 28 is configured as an annular structure fitted on the movable part 2402. The sealing member 28 is fixedly connected with the movable part 2402. The sealing member 28 can enter and exit the extension opening 21231 along with the sliding of the movable part 2402. When the movable part 2402 is in the storage position, the sealing member 28 is located on the side of the first sealing protrusion 24011 away from the mounting cavity 210, and the sealing member 28 abuts against the side of the first sealing protrusion 24011 away from the mounting cavity 210. The distance from the outer edge of the sealing member 28 to the axis of the sealing member 28 is greater than the distance from the inner edge of the first sealing protrusion 24011 to the axis of the first sealing protrusion 24011.

[0166] In this way, when the movable part 2402 moves to the working position, the sealing member 28 moves out of the extension opening 21231 along with the movable part 2402, and the sealing member 28 is not subjected to the extrusion of the housing 21; when the movable part 2402 moves to the storage position, the sealing member 28 abuts against the side of the first sealing protrusion 24011 away from the mounting cavity 210, and the sealing member 28 presses the side of the first sealing protrusion 24011 from the side of the first sealing protrusion 24011 away from the mounting cavity 210, thereby achieving a sealing effect. Since the sealing member 28 only produces a tight sealing effect when the movable part 2402 returns to the storage position, the wear of the sealing member 28 is small during long-term use, and the torque requirement of the power source driving the movable part 2402 is smaller. At the same time, the sealing member 28 is in contact with the side of the first sealing protrusion 24011 in the axial direction of the extension opening 21231, the sealing surface between the sealing member 28 and the first sealing protrusion 24011 is smooth and closely contacted, and the leakage rate is very low.

[0167] In an illustrative embodiment, the movable part 2402 is provided with a first mounting groove 24022. The first mounting groove 24022 is recessed inward from the outer circumferential surface of the movable part 2402. The first mounting groove 24022 can be configured as an annular groove extending along the circumference of the movable part 2402. The first mounting groove 24022 can be provided at the end of the movable part 2402 away from the mounting cavity 210. The inner edge of the sealing member 28 is embedded in the first mounting groove 24022 of the movable part 2402. The thickness of the inner edge of the sealing member 28 is greater than the width of the first mounting groove 24022. The sealing member 28 and the first mounting groove 24022 can be in interference fit.

[0168] Since the inner edge of the sealing member 28 is embedded in the first mounting groove 24022 of the movable portion 2402 , the sealing member 28 can be firmly fixed on the movable portion 2402 , and no gap exists between the sealing member 28 and the movable portion 2402 .

[0169] In an exemplary embodiment, the sealing member 28 is bonded to the movable portion 2402. The sealing member 28 may be bonded to the outer peripheral surface of the movable portion 2402 by adhesive.

[0170] The sealing member 28 is connected to the movable portion 2402 by bonding, which can firmly fix the sealing member 28 on the movable portion 2402 and ensure the sealing performance between the sealing member 28 and the movable portion 2402.

[0171] In an illustrative embodiment, a second sealing protrusion 24021 is provided on the movable portion 2402. The second sealing protrusion 24021 is provided at an end of the movable portion 2402 away from the mounting cavity 210. The second sealing protrusion 24021 extends radially outward from the outer peripheral surface of the movable portion 2402. The second sealing protrusion 24021 can be configured as an annular protrusion. The sealing member 28 is provided on a side of the second sealing protrusion 24021 close to the mounting cavity 210, and the sealing member 28 abuts the side of the second sealing protrusion 24021 close to the mounting cavity 210. The end surface of the sealing member 28 away from the mounting cavity 210 and the side surface of the second sealing protrusion 24021 close to the mounting cavity 210 can be adhesively connected. The side surface of the second sealing protrusion 24021 away from the mounting cavity 210 is flush with the end surface of the movable portion 2402 away from the mounting cavity 210.

[0172] In this way, when the movable part 2402 is in the storage position, the second sealing protrusion 24021 of the movable part 2402 can apply pressure to the seal 28 from the side of the seal 28 facing away from the first sealing protrusion 24011, and the pressure is directed toward the first sealing protrusion 24011, thereby improving the sealing performance between the first sealing protrusion 24011 and the seal 28.

[0173] In an exemplary embodiment, both end surfaces of the sealing member 28 are planar. The sealing member 28 is a flat gasket. The sealing member 28 can form a seal by abutting the side surfaces of the first sealing protrusion 24011 with the planar end surfaces. This sealing member 28 has a simple structure and is easy to process.

[0174] In another exemplary embodiment, Figure 21 As shown, both end faces of the seal 28a are conical. The apex of the conical surface faces the side closest to the mounting cavity 210. The seal 28a is configured as a conical washer. The side of the second sealing protrusion 24021 that abuts against the end face of the seal 28a can also be configured as a conical surface to better support the seal 28a.

[0175] The sealing member 28a can form a seal by abutting the side of the first sealing protrusion 24011 with the conical end surface. This sealing member 28a has a simple structure and is easy to process, and the sealing effect between the conical end surface and the first sealing protrusion 24011 is better.

[0176] In another exemplary embodiment, Figure 21 As shown, a second sealing protrusion 24021 is provided on the movable portion 2402. The second sealing protrusion 24021 can be configured as an annular protrusion. The second sealing protrusion 24021 extends radially outward from the outer circumference of the movable portion 2402. The second sealing protrusion 24021 is provided at the end of the movable portion 2402 that is away from the mounting cavity 210. The side of the second sealing protrusion 24021 that is away from the mounting cavity 210 is flush with the end surface of the movable portion 2402 that is away from the mounting cavity 210.

[0177] The seal 28a is constructed as an annular structure and is arranged on the inner wall of the extension port 21231. The outer edge of the seal 28a is connected to the inner wall of the extension port 21231. The movable portion 2402 is passed through the seal 28a, and there can be a clearance fit between the movable portion 2402 and the seal 28a. The seal 28a is located on the side of the second sealing protrusion 24021 close to the installation cavity 210. The distance from the inner edge of the seal 28a to the axis of the seal 28a is less than the distance from the inner edge of the second sealing protrusion 24021 to the axis of the second sealing protrusion 24021. When the movable portion 2402 is in the storage position, the seal 28a and the side of the second sealing protrusion 24021 close to the installation cavity 210 are abutted.

[0178] Thus, when the movable portion 2402 moves to the working position, the second sealing protrusion 24021 moves with the movable portion 2402 to the outside of the extension opening 21231, and the seal 28a is fixed to the extension opening 21231. The seal 28a is not squeezed by the second sealing protrusion 24021 of the movable portion 2402. When the movable portion 2402 moves to the storage position, the seal 28a abuts against the side of the second sealing protrusion 24021 near the installation cavity 210. The second sealing protrusion 24021 presses against the side of the second sealing protrusion 24021 from the seal 28a toward the installation cavity 210, thereby achieving a sealing effect. Because the second sealing protrusion 24021 only presses against the seal 28a when the movable portion 2402 returns to the storage position, the wear of the seal 28a is minimized during long-term use, and the torque requirement of the power source driving the movable portion 2402 is reduced. At the same time, the seal 28a contacts and seals with the side surface of the second sealing protrusion 24021 in the axial direction of the extension port 21231. The sealing surface between the seal 28a and the second sealing protrusion 24021 is flat and in close contact, and the leakage rate is very low.

[0179] In an illustrative embodiment, Figure 23 As shown, the outer edge of the sealing member 28b is bonded to the inner wall of the extension opening 21231 of the housing 21. The sealing member 28b can be bonded to the inner wall of the extension opening 21231 of the housing 21 by adhesive.

[0180] The sealing member 28b is connected to the housing 21 by bonding, which can firmly fix the sealing member 28b on the housing 21 and ensure the sealing performance between the sealing member 28b and the inner wall of the extension port 21231.

[0181] In another exemplary embodiment, Figure 25 As shown, a second mounting groove 24012 is provided on the inner wall of the extension opening 21231, and the outer edge of the sealing member 28c is embedded in the second mounting groove 24012. The second mounting groove 24012 can be formed by a depression in the inner wall of the extension opening 21231. The second mounting groove 24012 can be configured as an annular groove extending along the circumference of the extension opening 21231. The second mounting groove 24012 can be provided at one end of the extension opening 21231 near the mounting cavity 210. The inner edge of the sealing member 28c is embedded in the second mounting groove 24012. The sealing member 28c and the second mounting groove 24012 can be an interference fit.

[0182] Since the inner edge of the sealing member 28 c is embedded in the second mounting groove 24012 of the inner wall of the extension opening 21231 , the sealing member 28 c can be firmly fixed to the housing 21 , and no gap exists between the sealing member 28 c and the inner wall of the extension opening 21231 .

[0183] In an illustrative embodiment, Figure 25 As shown, the inner wall of the extension opening 21231 of the housing 21 is provided with a first sealing protrusion 24011 that protrudes radially inward. A second mounting groove 24012 is provided on a side of the first sealing protrusion 24011 that is away from the mounting cavity 210. The opening of the second mounting groove 24012 faces the sealing member 28c. The depth direction of the second mounting groove 24012 is parallel to the axial direction of the extension opening 21231.

[0184] The sealing member 28c includes a ring body 281c and an annular protrusion 282c. The ring body 281c is disposed on the side of the first sealing protrusion 24011 away from the mounting cavity 210. The annular protrusion 282c is disposed on the side of the ring body 281c closer to the first sealing protrusion 24011. The annular protrusion 282c may be disposed on the outer edge of the ring body 281c. The annular protrusion 282c is embedded in the second mounting groove 24012 on the inner wall of the extension opening 21231. The radial thickness of the annular protrusion 282c is greater than or equal to the width of the second mounting groove 24012.

[0185] In this way, an interference fit is formed between the seal 28c and the second mounting groove 24012 of the shell 21, and the seal 28c is fixed on the shell 21. At the same time, since the second mounting groove 24012 is arranged on the side of the first sealing protrusion 24011 away from the mounting cavity 210, it is convenient to insert the annular protrusion 282c into the second mounting groove 24012.

[0186] In another exemplary embodiment, Figure 28 , a plurality of seals 28 are provided, and the plurality of seals 28 include a first seal 28f and a second seal 28d. The first seal 28f is connected to the movable part 2402. The first seal 28f is constructed as an annular structure that is sleeved on the movable part 2402. There is a clearance fit between the first seal 28f and the inner wall of the extension port 21231. The second seal 28d is connected to the inner wall of the extension port 21231 of the housing 21. The second seal 28d is constructed as an annular structure that is arranged on the inner wall of the extension port 21231. The movable part 2402 is passed through the second seal 28d. There is a clearance fit between the second seal 28d and the movable part 2402. The outer diameter of the first seal 28f is larger than the inner diameter of the second seal 28d.

[0187] When the movable portion 2402 is located at the storage position, the first sealing member 28 f is located on a side of the second sealing member 28 d away from the installation cavity 210 , and the end surfaces of the first sealing member 28 f and the second sealing member 28 d that are close to each other abut against each other.

[0188] Thus, when the movable portion 2402 moves to the working position, the first seal 28f moves with the movable portion 2402 to the outside of the extension opening 21231, separating the first seal 28f from the second seal 28d, and no pressure is applied between the first seal 28f and the second seal 28d. When the movable portion 2402 moves to the storage position, the adjacent end surfaces of the first seal 28f and the second seal 28d abut against each other, partially overlapping and squeezing each other in the radial direction, thereby sealing the gap between the outer wall of the movable portion 2402 and the inner wall of the telescopic opening. Because the first seal 28f presses against the second seal 28d to achieve a seal only when the movable portion 2402 returns to the storage position, the wear of the first seal 28f and the second seal 28d is minimal during long-term use, and the torque requirement for the power source driving the movable portion 2402 is lower. At the same time, the end face of the first sealing member 28f contacts and seals with the end face of the second sealing member 28d. The sealing surface between the first sealing member 28f and the second sealing member 28d is flat and in close contact, and the leakage rate is very low.

[0189] In an exemplary embodiment, the first sealing member 28f is bonded to the movable portion 2402. The first sealing member 28f can be bonded to the movable portion 2402 using adhesive. Alternatively, the movable portion 2402 is provided with a first mounting groove 24022, and the inner edge of the first sealing member 28f is embedded in the first mounting groove 24022.

[0190] The first sealing member 28 f is adhered to the movable portion 2402 , or the inner edge of the first sealing member 28 f is embedded in the first mounting groove 24022 of the movable portion 2402 , so that the first sealing member 28 f can be firmly fixed on the movable portion 2402 .

[0191] In an illustrative embodiment, Figure 28 As shown, the second sealing member 28d is bonded to the inner wall of the extension opening 21231 of the housing 21. Alternatively, a second mounting groove 24012 is provided on the inner wall of the extension opening 21231 of the housing 21, and the outer edge of the second sealing member 28d is embedded in the second mounting groove 24012.

[0192] like Figure 28 As shown, the second sealing member 28d is bonded to the inner wall of the extension port 21231 of the housing 21, or as shown Figure 30 As shown, the outer edge of the second sealing member 28h is embedded in the second mounting groove 24012 of the inner wall of the extension opening 21231 , and the second sealing members 28d and 28h can be firmly fixed on the extension opening 21231 of the housing 21 .

[0193] In another exemplary embodiment, Figure 32 As shown, seal 28I is annular in structure. Seal 28I is encircled around the outer circumference of movable portion 2402. The outer edge of seal 28I is connected to the inner wall of extension opening 21231 or the outer circumference of movable portion 2402. The radial thickness of seal 28I is greater than the width of the gap between the outer circumference of movable portion 2402 and the inner wall of extension opening 21231.

[0194] When the movable part 2402 is in the storage position, the seal 28I is arranged in the gap between the inner wall of the extension port 21231 and the outer wall of the movable part 2402, and the seal 28I is compressed by the radial inward pressure exerted by the inner wall of the extension port 21231 and the radial outward pressure exerted by the movable part 2402.

[0195] In this way, since the seal 28I is in a compressed state, when the movable part 2402 is in the storage position, the outer peripheral surface of the seal 28I is tightly attached to the movable part 2402 and the seal 28I is tightly attached to the inner wall of the extension port 21231. The seal 28I blocks the gap between the outer peripheral surface of the movable part 2402 and the inner wall of the extension port 21231, thereby achieving sealing of the gap.

[0196] In another exemplary embodiment, Figure 34 As shown, the outer edge of the sealing member 28m is bonded to the inner wall of the extension opening 21231 of the housing 21. The sealing member 28m can be bonded to the inner wall of the extension opening 21231 of the housing 21 by adhesive.

[0197] The sealing member 28m is connected to the housing 21 by bonding, which can firmly fix the sealing member 28m on the housing 21 and ensure the sealing performance between the sealing member 28m and the inner wall of the extension port 21231.

[0198] In another exemplary embodiment, Figure 36 As shown, a second mounting groove 24012 is provided on the inner wall of the extension opening 21231, and the outer edge of the sealing member 28n is embedded in the second mounting groove 24012. The second mounting groove 24012 may be formed by a depression in the inner wall of the extension opening 21231. The second mounting groove 24012 may be configured as an annular groove extending along the circumference of the extension opening 21231. The second mounting groove 24012 may be provided at one end of the extension opening 21231 near the mounting cavity 210. The inner edge of the sealing member 28n is embedded in the second mounting groove 24012. The sealing member 28n and the second mounting groove 24012 may be an interference fit.

[0199] Since the inner edge of the sealing member 28n is embedded in the second mounting groove 24012 of the inner wall of the extension opening 21231 , the sealing member 28n can be firmly fixed to the housing 21 , and no gap exists between the sealing member 28n and the inner wall of the extension opening 21231 .

[0200] In an illustrative embodiment, Figure 27 As shown, the elastic compression amount A of the seal 28 is equal to the difference between the radial thickness of the seal 28 and the width of the gap between the outer peripheral surface of the movable portion 2402 and the inner wall of the extension opening 21231. The elastic compression amount A of the seal 28 has a value range of 0.15 mm ≤ A ≤ 1.3 mm.

[0201] When the elastic compression amount A of the seal 28 is within the above range, it can not only prevent the seal 28 and the movable part from changing from an interference fit to a clearance fit after multiple frictions, thereby reducing the sealing and dirt-blocking function of the seal 28, but also avoid the movable part 2402 from sliding and getting stuck due to excessive friction between the seal 28 and the movable part 2402.

[0202] In an illustrative embodiment, Figure 38 As shown, the sealing member 28p is in surface contact with the inner wall of the extension port 21231.

[0203] In an illustrative embodiment, Figure 39As shown, there is line contact between the sealing member 28q and the inner wall of the extension port 21231.

[0204] In one exemplary embodiment, seal 28 has a friction surface capable of slidingly rubbing against either the outer circumferential surface of movable portion 2402 or the inner wall of extension opening 21231. If seal 28 is fixedly connected to movable portion 2402, the friction surface is the outer circumferential surface of the seal ring; if seal 28 is fixedly connected to the inner wall of extension opening 21231, the friction surface is the inner circumferential surface of the seal ring.

[0205] In some embodiments, as Figure 37 As shown, in the cross section through the axis of the seal 281, the shape of the friction surface is an isosceles trapezoid.
