Description

Technical Field

[0001] The invention relates to the technical field of kitchen and bathroom products, in particular to a toilet seat. Background Art

[0002] The toilet is also called a toilet seat, which is a covered bucket for defecation and urination. The invention of the toilet is called a great invention, which solves the problem of people's eating, drinking, defecation and urination. Later, it gradually evolved into flush toilets using siphon, spiral siphon, and now the latest jet siphon and super-rotation siphon. There are many types of toilets, including split and connected ones. With the development of technology, many new varieties have also emerged.

[0003] Dr. Philip Terno of New York University pointed out that if the toilet lid is open when flushing, the instantaneous cyclone in the toilet can carry germs or microorganisms up to 6 meters in the air, and suspend in the air for several hours, and then fall on walls and objects. Therefore, you should develop the habit of covering the toilet lid when flushing. Professor Yu Qingfu of the School of Public Health of Fudan University pointed out that the survey found that 32% of toilets had Shigella dysenteriae, one of which was called "Songnei" Shigella dysenteriae, which survived on the toilet seat for up to 17 days. Another experimental report also pointed out that 100 million polio viruses were put into the toilet, and 3,000 viruses splashed on the seat. At the same time, many people like to put a flannel gasket or plastic foam gasket on the toilet in winter to avoid sitting directly on the cold seat, thereby improving comfort. This makes it easier to absorb and retain excreted pollutants, and the possibility of spreading diseases is greater. In most families nowadays, going to the toilet, washing, and showering are all done in the bathroom. Toothbrushes, mouthwash cups, towels, etc. are in the same room with the toilet, which is naturally easily contaminated by bacteria. The toilets in public toilets such as restaurants, hotels, cinemas, and stations are frequently used by different customers. If they are not cleaned in time, they are also prone to cross-infection of germs. The bacteria in the toilet mainly come from excrement and dirt and bacteria left on the wall of the toilet for a long time due to improper cleaning. At the same time, since most families and public places with small venues cannot provide a separate urinal in the men's toilet, the urination problem is also solved directly in the toilet, and urine is easily left on the top surface of the toilet. After the use of dysentery users, feces may also remain near the top side wall of the toilet, and this area is often a blind spot when flushing the toilet. Even if the toilet lid is covered in time for flushing, bacteria or dirt will still remain on the seat ring, and the remaining bacteria are easy to breed in large quantities on the bottom surface of the toilet seat ring that is not easy to observe.

[0004] Places with such serious pollution happen to be the most "intimate" contact with people's skin, so they should be cleaned intensively and wiped with disinfectant every one or two days. For public places that are frequently used, special cleaning staff are required to perform regular cleaning. This requires a lot of time, energy or financial resources, and if it is not cleaned in time after each use, it is possible that the germs have spread between different users during the cleaning interval. In order to solve the seat hygiene problem, disposable cushions have appeared on the market. Disposable cushions are laid on the toilet seat to avoid direct contact between the human body and the seat. This can effectively avoid the problem of cross-infection of germs to a certain extent, but the laying of disposable cushions requires the user to operate it himself, and even the disposable cushions that were not removed in time after the previous user used it need to be manually removed, which brings inconvenience to the user. For cleaning staff in public places, it is impossible to pay attention to the use of the toilet by each customer at any time and be ready to check or replace the disposable cushions at any time.

DETAILED DESCRIPTION

[0083] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0084] Embodiment 1:

[0085] See also Figure 1 A toilet seat comprises a cover base 1 and a seat body 2 hinged to the cover base 1. Preferably, a top cover 3 is also hinged on the top of the cover base 1. The cover base 1, the seat body 2 and the top cover 3 are main components of an existing general toilet seat. The specific structural form and connection form are the same or similar to those of an existing general toilet, which will not be described in detail here.

[0086] The cover base 1 is hinged with an upper tank shell 4 that can be movably buckled and covered on the upper outer side of the seat ring body 2, and the top cover 3 can be movably buckled and covered on the outer side of the upper tank shell 4. Figure 2 and Figure 3 As shown, the upper tank shell 4 is a shell structure with an opening at the bottom, and its outer contour is similar to that of the seat ring body 2. The outer dimensions of the upper tank shell 4 are equivalent to those of the seat ring body 2 and are smaller than the inner dimensions of the top cover 3. A hinge joint 405 is integrally provided on the rear end side of the upper tank shell 4. The hinge joint 405 is hinged with the pin shaft at the top of the cover base 1, so that the upper tank shell 4 can rotate around the pin shaft. When the upper tank shell 4 is flipped up to a vertical state, it can be completely accommodated in the top cover 3 (such as Figure 7 As shown), when the upper tank shell 4 is turned down to a horizontal state, its edge can overlap the top edge of the seat ring body 2, or connect to the outer side of the top edge of the seat ring body 2 (as shown in FIG. Figure 8 When the toilet is not in use, the top cover 3 is flipped down to a horizontal state and buckled on the top outer side of the upper tank shell 4 (as shown in FIG. Fig. 9 shown).

[0087] A water supply pipe 5 is fixedly arranged on the inner side of the bottom of the upper tank shell 4. Figure 4 and Figure 5 As shown, in this embodiment, the outer contour of the upper water pipe 5 matches the groove contour of the upper tank shell 4, which is a hollow shell structure, and at least one row of upper drainage holes 501 distributed in an annular pattern are provided on the bottom surface of the upper water pipe 5. A water pipe insertion hole 406 and an air pipe insertion hole 407 are provided on the rear end side wall of the upper tank shell 4, and a water pipe connecting column 503 is integrally provided on the rear end side wall of the upper water pipe 5. Figure 6As shown, the upper water pipe 5 is fixedly embedded in the upper tank shell 4, and the fixed assembly is achieved by the tight fit between the outer side of the upper water pipe 5 and the inner side of the upper tank shell 4. At this time, the top surface of the upper water pipe 5 abuts against the top surface of the tank of the upper tank shell 4, the outer side of the upper water pipe 5 abuts against the inner side of the upper tank shell 4, and the water pipe connecting column 503 is located in the water pipe insertion hole 406. In order to further ensure the fixed embedding of the upper water pipe 5 in the upper tank shell 4, the top surface of the upper water pipe 5 and the top surface of the tank of the upper tank shell 4 can be fixedly connected by gluing.

[0088] The water inlet end of the upper water pipe 5 (water pipe connecting column 503) is connected to the water outlet end of the water pump 7 through the water inlet pipeline 6, and the interior of the upper tank shell 4 is connected to the air outlet end of the air pump 9 through the air inlet pipeline 8. The air outlet end of the air inlet pipeline 8 is fixedly arranged in the air pipe jack 407 on the rear end side of the upper tank shell 4. The power supply end of the water pump 7 and the air pump 9 is provided with a control switch assembly 13. In this embodiment, Fig.10 As shown, the control switch assembly 13 includes a first manual switch 131 connected in series to the power supply end of the water pump 7 and a second manual switch 132 connected in series to the power supply end of the air pump 9. The first manual switch 131 starts the water pump 7 alone, and the second manual switch 132 starts the air pump 9 alone.

[0089] When the upper tank shell 4 is buckled onto the seat ring body 2, the upper water pipe 5 is located above the top surface of the seat ring body 2, the first manual switch 131 is pressed, the water pump 7 is started, the water pump 7 supplies water into the upper water pipe 5, the water is sprayed through the upper drainage hole 501 to wash the top surface of the seat ring body 2, the second manual switch 132 is pressed, the air pump 9 is started, the air pump 9 supplies gas to the inside of the upper tank shell 4, and the gas dries the top surface of the seat ring body 2. In this way, the rinsing and drying process of the top surface of the seat ring body 2 can be completed, and the top surface of the seat ring body 2 can be cleaned. This control switch group 13 can realize the manual cleaning operation of the top surface of the seat ring body 2.

[0090] In another embodiment, Fig.10 and Fig.11As shown, the control switch assembly 13 also includes a switch housing 133 and a third manual switch 134. The water pump 7 and the air pump 9 are fixedly arranged in the switch housing 133. The switch housing 133 is also fixedly provided with a controller 15. The first manual switch 131, the second manual switch 132 and the third manual switch 134 are respectively embedded in the side of the switch housing 133 (the front cover of the switch housing 133) and are respectively electrically connected to the controller 15. The third manual switch 134 is used to start the water pump 7 and the air pump 9 to work in sequence. The front cover of the switch housing 133 is also respectively embedded with a main switch 135 and a power indicator light 137. The main switch 135 is connected in series to the power supply end of the controller 15 for start and stop control of the controller 15. The power indicator light 137 is electrically connected to the controller 15 for displaying the power-on status of the controller 15. Since the control switch assembly 13 is only used for simple logic control and digital-to-analog conversion, a general simple controller with a single-chip microcomputer core can be used. When the main switch 135 is pressed, the controller 15 is powered on and the power indicator light 137 is lit. At this time, the first manual switch 131 is pressed to start the water pump 7 to work alone. The water pump 7 supplies water to the upper water pipe 5, and the water is sprayed through the upper drainage hole 501 to wash the top surface of the seat ring body 2; the second manual switch 132 is pressed to start the air pump 9 to work alone. The air pump 9 supplies gas to the interior of the upper tank shell 4, and the gas dries the top surface of the seat ring body 2; when the third manual switch 134 is pressed, the controller 15 executes the corresponding built-in program, automatically starts the water pump 7 to work alone for a preset time, and washes the top surface of the seat ring body 2. After the rinsing is completed, the air pump 9 is automatically started to work alone for a preset time to dry the top surface of the seat ring body 2. This control switch group 13 can realize manual cleaning and automatic cleaning operations on the top surface of the seat ring body 2.

[0091] In another embodiment, the air outlet of the air pump 9 is also fixedly provided with an electric heating device 14, and the second manual switch 132 is connected in series to the power supply end of the electric heating device 14. After pressing the second manual switch 132 or the third manual switch 134, the electric heating device 14 and the air pump 9 start working at the same time, and the electric heating device 14 heats the gas output by the air pump 9 and then sends out hot air through the air intake pipe 8. The hot air dries the top surface of the seat ring body 2, which can effectively speed up the drying process. In cold weather, the second manual switch 132 can also be pressed to start the electric heating device 14 and the air pump 9, and the surface of the seat ring body 2 is heated by hot air to improve the user's comfort.

[0092] like Fig.12 As shown, in another embodiment, preferably, the upper drainage holes 501 are evenly distributed on the bottom surface of the upper water pipe 5. The state of the upper water pipe 5 being embedded in the upper tank shell 4 is as shown in FIG. Fig.13 shown.

[0093] like Fig.14 and Fig.15 As shown, in another embodiment, an upper positioning column 408 is integrally provided on the top surface of the upper tank shell 4, and an upper plugging notch 504 corresponding to the upper positioning column 408 is integrally provided on the top surface of the upper water pipe 5. After the upper water pipe 5 is embedded in the upper tank shell 4, the upper positioning column 408 and the upper plugging notch 504 are plugged in tightly to fix the position of the upper water pipe 5 in the upper tank shell 4, so that a gap is left between the top surface of the upper water pipe 5 and the top surface of the tank of the upper tank shell 4. The bottom surface of the upper water pipe 5 can also be threadedly connected to the upper positioning column 408 by screws to further ensure the fixed connection between the upper water pipe 5 and the upper tank shell 4.

[0094] like Fig.16 and Fig.17 As shown, in another embodiment, an upper positioning notch 409 is integrally provided on the top surface of the upper tank shell 4, and an upper plugging column 505 connected to the upper positioning notch 409 is integrally provided on the top surface of the upper water pipe 5. After the upper water pipe 5 is embedded in the upper tank shell 4, the upper plugging column 505 is tightly plugged in and fits with the upper positioning notch 409 to fix the position of the upper water pipe 5 in the upper tank shell 4, so that a gap is left between the top surface of the upper water pipe 5 and the top surface of the tank of the upper tank shell 4. The top surface of the upper tank shell 4 can also be threadedly connected to the upper plugging column 505 by screws to further ensure the fixed connection between the upper water pipe 5 and the upper tank shell 4.

[0095] like Fig.18 and Fig.19 As shown, in another embodiment, as the best choice, an upper positioning boss 401 is integrally provided on the top surface of the groove of the upper trough shell 4. After the upper water pipe 5 is embedded in the upper trough shell 4, the top surface of the upper water pipe 5 abuts against the bottom surface of the upper positioning boss 401, so that a gap is left between the top surface of the upper water pipe 5 and the top surface of the groove of the upper trough shell 4. An upper alignment block 402 is integrally provided on the inner side surface of the upper trough shell 4, and an upper alignment groove 410 is provided on the side of the upper alignment block 402. An alignment flange 502 that matches the upper alignment groove 410 is provided on the side of the upper water pipe 5. Through the cooperation of the alignment flange 502 and the upper alignment groove 410, the upper water pipe 5 can be quickly and accurately aligned in the upper trough shell 4, which facilitates the embedding operation of the upper water pipe 5 in the upper trough shell 4. The embedded state of the upper water pipe 5 in the upper trough shell 4 is shown in FIG. Fig.18 The upper water pipe 5 and the upper tank housing 4 can be fixedly connected by screws arranged in the alignment flange 502 and threadedly connected with the upper positioning boss 401 .

[0096] An upper alignment groove (not shown) may also be provided on the side of the upper water pipe 5, so that after the upper water pipe 5 is inserted into the upper tank housing 4, the upper alignment blocks 402 are respectively embedded in the upper alignment grooves to achieve the same positioning effect as above. A protrusion may also be provided on the side of the upper alignment block 402, and a groove that matches the protrusion may be provided on the side wall of the upper water pipe 5, and the above positioning effect may be achieved through the cooperation of the protrusion and the groove.

[0097] Obviously, other similar docking structures may also be used to achieve the above-mentioned positioning and installation effect of the upper water pipe 5 in the upper tank shell 4.

[0098] Embodiment 2:

[0099] See also Figure 20 to Figure 22 Based on the structure of Example 1, a downpipe 11 is fixedly disposed on the inner side of the bottom of the seat ring body 2, and a lower tank housing 12 located below the downpipe 11 is fixedly disposed on the outer side of the bottom of the seat ring body 2. Fig.23 and Fig.24 As shown, the outer contour of the down pipe 11 is similar or identical to that of the upper pipe 5, and is also a hollow shell structure. At least one row of annularly distributed lower drainage holes 111 are provided on the top surface of the down pipe 11. A water pipe connection column is also integrally provided on the rear end side wall of the down pipe 11. Fig.25 and Fig.26 As shown, a lower positioning boss 204 is integrally provided on the bottom surface of the groove of the seat ring body 2, and a lower alignment block 202 is integrally provided on the inner side surface of the seat ring body 2. After the lower upper water pipe 11 is fixedly embedded in the seat ring body 2, the fixed assembly is achieved through the tight fit between the outer side surface of the lower water pipe 11 and the inner side surface of the upper and lower alignment blocks 202. At this time, the top surface of the lower water pipe 11 abuts against the surface of the lower positioning boss 204, and the water pipe connecting column penetrates the rear end side wall of the seat ring body 2, so that a gap is left between the top surface of the lower water pipe 11 and the top surface of the groove of the seat ring body 2, and a gap is left between the outer side surface of the lower water pipe 11 and the inner side surface of the seat ring body 2 (such as Fig. 27 As shown). In this way, after the water sprayed upward from the lower drainage hole 111 washes the top surface of the groove of the seat ring body 2, the water can flow downward from the gaps on the top and sides. To further ensure that the downpipe 11 is fixedly embedded in the seat ring body 2, the top surface of the downpipe 11 and the surface of the lower positioning boss 204 can be fixedly connected by gluing or screwing.

[0100] like Fig.28 As shown, in another embodiment, preferably, the upper drainage holes 501 are evenly distributed on the bottom surface of the upper water pipe 5 .

[0101] like Fig.29 and Fig.30As shown, in another embodiment, a lower positioning column 205 is integrally provided on the groove top surface of the seat ring body 2, and a lower plug-in slot 112 corresponding to the lower positioning column 205 is integrally provided on the top surface of the downpipe 11. After the downpipe 11 is embedded in the seat ring body 2, the downpipe 11 is fixed in position in the seat ring body 2 through the plug-in tight fit between the lower positioning column 205 and the lower plug-in slot 112, so that a gap is left between the top surface of the downpipe 11 and the groove top surface of the seat ring body 2, and a gap is left between the side surface of the downpipe 11 and the inner side surface of the seat ring body 2 by making the outer dimensions of the downpipe 11 smaller than the groove cavity dimensions of the seat ring body 2. The bottom surface of the downpipe 11 can also be threadedly connected to the lower positioning column 205 by screws to further ensure the fixed connection between the downpipe 11 and the seat ring body 2.

[0102] like Fig.31 and Fig.32 As shown, in another embodiment, a lower positioning notch 206 is integrally provided on the groove top surface of the seat ring body 2, and a lower plug-in column 113 corresponding to the lower positioning notch 206 is integrally provided on the top surface of the downpipe 11. After the downpipe 11 is embedded in the seat ring body 2, the position of the downpipe 11 in the seat ring body 2 is fixed by plugging and tightly fitting between the lower plug-in column 113 and the lower positioning notch 206, so that a gap is left between the top surface of the downpipe 11 and the groove top surface of the seat ring body 2, and a gap is left between the side surface of the downpipe 11 and the inner side surface of the seat ring body 2 by making the outer dimensions of the downpipe 11 smaller than the groove cavity dimensions of the seat ring body 2. The top surface of the seat ring body 2 can also be threadedly connected to the lower plug-in column 113 by screws to further ensure the fixed connection between the downpipe 11 and the seat ring body 2.

[0103] Obviously, other similar docking structures may also be used to achieve the above-mentioned positioning and installation effect of the downcomer pipe 5 in the seat ring body 2 .

[0104] like Fig.33 and Fig.34 As shown, the lower tank shell 12 is a shell structure with an opening at the top. The outer contour of the lower tank shell 12 is the same as that of the upper tank shell 4. When the upper tank shell 4 is buckled on the seat ring body 2, the bottom surface of the side wall of the upper tank shell 4 is against the top surface of the side wall of the lower tank shell 12, and a nearly sealed cavity channel is formed between the upper tank shell 4 and the lower tank shell 12, and the seat ring body 2 is surrounded therein. Fig.36 A plurality of stepped bosses 124 are integrally provided at the junction of the side wall and the bottom wall of the lower tank shell 12. When the lower tank shell 12 is buckled under the seat ring body 2, the bottom surface of the seat ring body 2 abuts against the top surface of the stepped bosses 124, and the outer side surface of the seat ring body 2 abuts against the side surface of the stepped bosses 124. Through the tight fit between the seat ring body 2 and the stepped bosses 124, the lower tank shell 12 is fixedly sleeved on the outer side of the bottom of the seat ring body 2 (as shown in FIG. Fig.35shown).

[0105] like Figure 37 to Figure 39 As shown, in another embodiment, a lower alignment block 202 is integrally provided on the inner side of the seat ring body 2, a plug-in port 203 is provided on the bottom surface of the lower alignment block 202, a plug-in through hole 122 corresponding to the plug-in port 203 is provided on the bottom surface of the lower tank shell 12, and a support block 13 is provided at the bottom of the lower tank shell 12, and the side walls on both sides of the top of the support block 13 penetrate the plug-in through hole 122 and are plugged into the plug-in port 203 (as shown in FIG. Fig.40 and Fig.41 As shown). In this way, when the seat ring body 2 is in a horizontal state, the bottom surface of the support block 13 abuts against the top surface of the toilet bowl 20, avoiding the bottom surface of the lower tank shell 12 from directly contacting the top surface of the toilet bowl 20, thereby avoiding the lower tank shell 12 from being deformed and damaged by the squatting force during normal use of the toilet, resulting in a significant reduction in service life. At the same time, through the fixed connection between the support block 13 and the seat ring body 2, the lower tank shell 12 is fixedly clamped between the two, which can simplify the fixed connection structure between the lower tank shell 12 and the seat ring body 2, and also facilitate the separation of the lower tank shell 12 from the seat ring body 2 for internal inspection or replacement of components.

[0106] The rear side of the seat ring body 2 is integrally provided with at least one (such as Figure 25 to Figure 27 The two (two shown in the figure) are hinged to the top of the cover base 1, and the hinged arm 201 is hinged to the cover base 1 through a pin, so that the seat ring body 2 can rotate around the pin, thereby realizing the conversion between the vertical state and the horizontal state. In order to make the bottom surface of the side wall of the upper tank shell 4 abut against the top surface of the side wall of the lower tank shell 12 when the upper tank shell 4 is buckled on the seat ring body 2, a notch 404 matching the hinged arm 201 is opened on the rear side wall of the upper tank shell 4, as shown in the figure. Fig.42 The matching state between the notch 404 and the articulated arm 201 is shown in FIG. Fig.43 shown.

[0107] The water inlet end (water pipe connection column) of the down pipe 11 is connected to the water outlet end of the water pump 7 through the water inlet pipeline 6. There is a gap between the top surface of the down pipe 11 and the inner top surface of the seat ring body 2, and between the outer side surface of the down pipe 11 and the inner side surface of the seat ring body 2, and the gap is connected to the interior of the lower tank shell 12. The interior of the lower tank shell 12 is connected to the air outlet end of the air pump 9 through the air inlet pipeline 8. Press the first manual switch 131 to start the water pump 7. The water pump 7 supplies water to the upper water pipe 5 and the down pipe 11 at the same time. The water in the upper water pipe 5 is sprayed downward through the upper drainage hole 501 to wash the top surface of the seat ring body 2 (such as Fig.36 The water in the downpipe 11 is sprayed upward through the downpipe hole 111 to wash the bottom surface of the seat ring body 2 (as shown in the solid arrow in FIG. Fig.36The liquid after flushing the top surface of the seat ring body 2 flows downward from both sides of the top surface of the seat ring body 2 into the lower tank shell 12, and the liquid after flushing the bottom surface of the seat ring body 2 directly flows downward from both sides of the downpipe 11 into the lower tank shell 12. At least one drainage port 123 is provided on the inner side of the bottom surface of the lower tank shell 12 (as shown in FIG. Fig.33 and Fig.34 As shown), the liquid flowing into the lower tank shell 12 flows out through the drain port 123 and enters the toilet bowl of the toilet 20, and the toilet bowl of the toilet 20 can be flushed.

[0108] After the flushing is completed, press the second manual switch 132 to start the air pump 9, and the air pump 9 supplies gas to the interior of the upper tank shell 4 and the lower tank shell 12 at the same time, and the gas dries the top surface and the bottom surface of the seat ring body 2 at the same time. In this way, the flushing and air-drying process of the top surface of the seat ring body 2 can be completed, and the top surface of the seat ring body 2 can be cleaned. The third manual switch 134 can also be pressed to start the automatic flushing and air-drying program, and the process of automatic flushing and automatic air-drying is completed. The electric heating device 14 heats the gas output by the air pump 9 and then sends hot air out through the air intake pipe 8. The hot air dries the top surface of the seat ring body 2, which can effectively speed up the air-drying process.

[0109] As a preferred example, Fig.44 and Fig.45 As shown, the outer side of the bottom surface of the side wall of the upper tank shell 4 is provided with an outer stepped surface 403, and the inner side of the top surface of the side wall of the lower tank shell 12 is provided with an inner stepped surface 121. When the upper tank shell 4 is buckled on the seat ring body 2, the bottom surface of the side wall of the upper tank shell 4 abuts against the inner stepped surface 121, and the top surface of the side wall of the lower tank shell 12 abuts against the outer stepped surface 403 (as shown in FIG. Fig.46 Such a structure can enhance the airtightness of the cavity between the upper tank shell 4 and the lower tank shell 12, prevent the water entering the lower tank shell 12 from overflowing from the intersection between the two, and facilitate the upper tank shell 4 to turn from a vertical state to a horizontal state and smoothly dock with the lower tank shell 12.

[0110] In another embodiment, the air outlet end of the air pump 9 is respectively connected to the water inlet ends of the upper water pipe 5 and the lower water pipe 11 (not shown in the figure), or the air outlet end of the air pump 9 is connected to the water inlet end of the water inlet pipe 6. Then, after the flushing operation of the upper and lower surfaces of the seat ring body 2 is completed, the gas delivered by the air pump 9 enters the upper water pipe 5 and the lower water pipe 11 respectively through the water inlet pipe 6, thereby blowing out the residual liquid in the upper water pipe 5 and the lower water pipe 11 to realize the air-drying process, and at the same time, the upper and lower surfaces of the seat ring body 2 are air-dried.

[0111] In another embodiment, the air outlet end of the air pump 9 is guided to the inner side of the front end of the upper tank shell 4 through the air inlet pipe 8, and the gas delivered by the air pump first dries the front end middle part of the cavity formed by the upper tank shell 4 and the lower tank shell 12, and the airflow is divided into two paths from the front end to the left and right parts and converges to the middle part of the rear end, and flows out through the drain port 123 on the lower tank shell 12, ensuring that the gas can effectively reach every position and corner in the cavity, reducing gas loss while allowing the internal space of the cavity and each component to be fully dried.

[0112] In the toilet seat of the present invention, the upper water pipe 5 is fixedly arranged in the upper tank shell 4, and the upper tank shell 4 is connected to the cover base 1. Therefore, the upper water pipe 5 and the upper tank shell 4 are pre-assembled into an upper cleaning component, and then assembled as a whole to the toilet 20 for use. It is also possible to directly replace the component in the later use process to cooperate with the normal use of the remaining components. The specific structural form of the upper water pipe 5 and the upper tank shell 4 and the specific connection form between the two can be any one of the forms listed in the above-mentioned embodiments.

[0113] Similarly, the downpipe 11 is fixedly arranged on the inner side of the bottom of the seat ring body 2, and the lower tank shell 12 is fixedly sleeved on the outer side of the bottom of the seat ring body 2. Therefore, the downpipe, the seat ring body 2 and the lower tank shell 12 can also be pre-assembled into a lower cleaning component, and then assembled as a whole on the toilet 20 for use. It is also possible to directly replace the components in the later use process to cooperate with the normal use of the remaining components. The specific structural form of the downpipe, the seat ring body 2 and the lower tank shell 12 and the specific connection form between them can be any one of the forms listed in the above embodiments. Or the upper cleaning component and the lower cleaning component are used as an integral component and are installed as a whole on the toilet 20 for use.

[0114] like Figures 7 to 9 ,as well as Fig.47 and Fig.48 A toilet is shown, on which is provided a toilet seat composed of an upper cleaning component or an integral component formed by any of the aforementioned structural forms, which can achieve water cleaning and heated air drying of the upper and lower surfaces of the seat body 2 to improve the cleanliness of the surface of the seat body 2 and reduce the possibility of bacterial growth, thereby improving the user's sanitary environment and reducing the probability of cross infection.

[0115] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
