Description

Technical Field

[0001] The present invention relates to the technical field of sanitary ware, in particular to a toilet, a squat toilet and a water tank with the functions of exhaust, splash prevention, sliding assistance and noise reduction. Background Art

[0002] In existing bathrooms, the odor generated by defecation is mainly discharged by the ventilation fan on the top. Since toilets and squat toilets are the main sanitary ware for defecation, the heat and odor generated by human defecation will spread upward and around. The ventilation fan is located at the top of the bathroom, so the human body is between the feces and the ventilation fan and will smell the odor. Relying solely on the ventilation fan cannot fundamentally solve the fundamental reason for timely and complete discharge of odor from the bathroom. Therefore, the key to solving the problem is to discharge the odor in a timely manner at the closest distance to the feces. In addition, the ventilation fan is generally too noisy and cannot provide a relatively quiet environment.

[0003] Existing toilets and squat toilets focus on whether the flushing water covers the entire inner wall and different flushing methods. The purpose is to flush away all the feces hanging on the wall. If there is too much feces hanging on the wall, it cannot be flushed away. Only when the feces do not hang on the inner wall at all or hang less on the wall can the sanitary ware be flushed clean with less water.

[0004] Existing toilets and squat toilets have not completely solved the problem of splashing water when defecation. Some use baffles, and some use foam. These methods do not fundamentally solve the problem of splashing water, because feces falling directly into the water or into water with foam will cause splashing water due to gravity. The splashing problem can only be solved by preventing excrement from falling directly into the water.

[0005] Existing toilets, squat toilets, and flush tanks have single functions and occupy the same position, and the limited space is not fully utilized. The use of toilets, squat toilets, and flush tanks that integrate multiple functions such as flushing, exhaust, sliding, and paper towel storage will effectively increase product functions and value. Summary of the Invention

[0006] The present invention relates to a sanitary ware, in particular to a toilet and a squat toilet as well as a water tank with exhaust, sliding-aiding, splash-proof and noise-reducing functions, so as to solve the above-mentioned technical problems. To achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a sanitary ware, including a toilet, a toilet A, a squat toilet, a wall-mounted water tank, a hidden water tank body and the shape of the body, a combination of the wall-mounted water tank and the squat toilet, and a combination of the hidden water tank and the squat toilet; the said sanitary ware includes exhaust, paper towel storage, splash prevention, skid assisted, noise reduction, flushing water guide hole and a common pipe between the flushing hole and the exhaust, a common pipe between the skid assisted water and the flushing tank overflow, a connection between the exhaust device and the pre-buried exhaust pipe, a connection between the exhaust pipe and the ventilation fan, a common component between the water tank overflow and the skid assisted water, a skid assisted water control and water guide groove, a skid assisted hole, a common water guide hole between the flushing water and the skid assisted water, a paper towel storage area, an integrated circuit control system, an exhaust channel, a layout of holes on the front, rear, left and right sides of the inner walls of the toilet, toilet A and the squat toilet, a water trap storage area and the layout of the front and rear walls, a front and rear layout of a siphon and a sewage outlet of the squat toilet, The water tanks of the toilets and toilet A are provided with a disinfectant water storage, a water pump required to pump out the disinfectant water, and a water pump required to pump out the water for water skiing; The water inlet controller is connected to the water inlet angle valve, the flushing control component needs to be used in conjunction with the flushing water and electricity control component and the manual pressing device, and the flushing controller is integrated with the overflow port and the water-aiding interface; The integrated circuit control system is connected to the flushing water and electricity control unit, the exhaust fan, the atomizing nozzle, the ventilation fan, the body button, the water pump, the electronic water valve, the remote control, the wall control button, the sensors with different sensing modes, the seat heating and sensing device, and the multi-functional areas such as body washing and blowing heating. The above connections will be selectively connected according to the needs of different products to perform functional control of the product; The toilet and toilet A are equipped with an atomizing nozzle, a paper towel storage area, and a hollow space. The atomizing nozzle can regularly pump disinfectant water through a water pump to spray and disinfect the inner wall of the toilet. The paper towel storage area can store paper towels needed for the toilet. The hollow space design is convenient for taking out paper towels and placing objects. There is a toilet tank cover above the paper towel storage area. The toilet tank cover can use a plastic cover or a ceramic cover, and there is an anti-collision sealing strip at the contact between the cover and the water tank; The toilet A is provided with a paper towel storage function which will be subsequently applied and expanded to a combination of a squat toilet and a wall-mounted water tank; The exhaust hose interface is connected to one of the following pre-buried pipes and is connected to the ventilation fan interface on the ceiling using a three-way pipe fitting, and the odor is discharged to the outside through the exhaust hole on the top of the bathroom. There are two ways to pre-buried the pre-buried pipe. The first way is to pre-bury it upwards in the wall behind the product installation position until it reaches the inside of the ceiling. The second way is to first pre-bury it horizontally along the wall in the wall behind the product installation position to the position of the main sewage pipe in the bathroom and then go up to the inside of the ceiling next to the main sewage pipe. The other way is to open a hole in the wall at a suitable position below the product exhaust fan if the site conditions permit, and then insert the exhaust hose interface into the hole to discharge the odor to the outside. Currently, bathrooms only have a main sewage pipe and a sewage ventilation pipe. With the development of society, later bathrooms will be designed with a separate exhaust main pipe, so the exhaust pipe of the present invention will be connected to the gas main pipe to discharge the odor to the outside. The pre-buried pipe next to the main sewage pipe will selectively use a square pipe or a round pipe according to the site conditions. The pre-buried pipes and pipe joints, as well as all necessary connecting pipes and exhaust fans, will be treated to reduce noise and be wrapped with damping sheets and sound-insulating or sound-absorbing cotton. The noise level of the bathroom exhaust equipment during operation will be controlled within 35 decibels. The exhaust fan is currently designed to be integrated with the product, but it can also be made into a separate part and installed in the bathroom ceiling. The lower interface of the segmented pre-buried pipe is a conventional pipe diameter, the upper end of the pipe is about 40 mm long and is the upper interface, and the inner diameter is the same as the outer diameter of the lower interface of the connecting pipe. In this way, the risk of water leakage from the pipe joint is reduced by pre-buried pipes in the wall. The wall-mounted water tank and squat toilet combination, toilet, and exhaust passage of toilet A are provided with a drain valve, which is mainly used to discharge condensed water generated by exhaust in the pipeline; The wall-mounted water tank is provided with a unique structure of a floor-standing decorative shell and the entire water tank facilities and equipment; The special-shaped connecting pipes used in the exhaust fan of the wall-mounted water tank can be rotated left and right in cooperation with the common pipe; the water tank and the decorative shell can be combined into one or two parts. The split part means that after all the accessories are installed, the shell is clamped on the equipment, and the entire equipment is covered in the shell, which not only protects the safety of the equipment but also makes the product appearance more neat and perfect. The hidden flush tank and related auxiliary accessories are installed on the ceiling. The rear water outlet at the bottom of the water tank is connected to the pre-buried pipe, and the front pipe opening is connected to the exhaust, overflow, and water-slide pipes. The exhaust fan is located at the upper front end of the water tank. An air inlet is opened on the water tank to the right rear of the exhaust fan. The air inlet is connected to the air intake pipe, and the front end of the air intake pipe is connected to the exhaust pipe at the front end of the exhaust device. The exhaust passages of the toilet and toilet A are drawn from the flushing holes and the sliding-aiding holes, passing through the inner cavity flushing water device, through the rear wall of the water tank, and then first upward and then turning downward to connect to the exhaust machine; the exhaust passages of the squat toilet are divided into two types. The first type is a squat toilet and a wall-mounted water tank combination, in which air is drawn from the flushing holes and the sliding-aiding holes, passing through the squat toilet inner cavity and the common pipe connected to the special-shaped connecting pipe fitting and connected to the exhaust machine; the second type is a squat toilet and a hidden water tank combination, in which air is drawn from the flushing holes and the sliding-aiding holes, passing through the squat toilet inner cavity and connected to the pre-buried pipe and the exhaust machine; the exhaust machine is then connected to the exhaust hose; The inner cavity flushing water guide hole is a common hole for exhaust, flushing water, overflow water, and skiing water to flow through the channel; the skiing water and the water tank overflow channel will also share the overflow pipe next to the flushing water control component; The sliding water is water flowing out through the sliding holes, forming a layer of flowing water in the feces falling area of the inner wall. The sliding water helps the feces slide down to the water storage area of the water trap, reducing the probability of feces sticking to the wall. The inner front wall of the toilet, toilet A and squat toilet is raised to increase the area where feces fall and the slope of the feces sliding down to the water storage area of the trap, thereby reducing the height of feces falling to the inner wall; The inner rear wall of the toilet and toilet A is recessed to increase the feces landing area. The water storage area also recedes to reduce the probability of feces falling directly into the water storage area. The water storage area of the conventional toilet is transformed into the feces landing area and the sloped sliding area of the present invention. The rear wall of the squat toilet has a forward convexity to prevent feces from falling directly into the water storage area; the outermost convex point of the rear outer wall of the water trap is within the vertical line of the rear edge of the squat toilet panel, so that there is space for the water trap water storage area to retreat behind the front convex point of the rear wall of the squat toilet, and the conventional squat toilet water trap water storage area is transformed into the feces landing area of the present invention; a sliding flushing port is provided between the rear end of the front wall and the water trap water storage area. The sliding water flowing out of the sliding flushing port can assist the sliding of feces, and the flowing flushing water will also flush the lower section of the rear wall; The water skiing aid is to use a water pump or an electronic water valve and other equipment to pump the water in the water tank through an overflow pipe or a flushing pipe and an inner cavity flushing guide hole and finally discharge it into the water skiing aid hole. The water skiing aid guide groove will share the inner cavity flushing water guide hole. The water skiing aid guide groove is composed of a water retaining groove, a watershed, a diversion groove, etc. in the inner cavity. The water skiing aid hole is located between the flushing holes and is distributed in the front, back, left and right of the inner wall. The number of openings of the water skiing aid hole and the overall flow rate of the hole diameter are equal to or less than the incoming water flow rate. The opening angle of the water skiing aid hole in the front section of the inner wall is downward and backward, the middle front section is tilted downward and backward, the middle section is downward, and the rear section is downward and forward. The flushing tank is provided with an overflow port, the upper end of which is provided with a hole for connecting to the water slide pipe, the overflow port is provided with a cover plate, a sealing rubber pad is provided under the cover plate, and a connecting arm is provided on the cover plate, which is connected to the float and the rotating shaft; The squat toilet's rear connection port is square, the distance between the squat toilet panel and the flushing hole is thinner, the inner cavity is lower, the extrusion force is increased, and the flushing force is stronger. The connecting pipe fittings used for the squat toilet's rear connection port are divided into two types of pipe shapes. The first type is a square pipe fitting, and the second type of pipe fitting is square at one end and round at the other end. The common pipe required for the combination of the squat toilet and the wall-mounted water tank is a special-shaped pipe fitting. The middle pipe diameter of the pipe fitting is larger than the pipe diameter of the two end interfaces. The common pipe is respectively connected to the exhaust pipe special-shaped pipe fitting, the water tank height adjustment joint, and the square-to-round special-shaped pipe fitting.

DETAILED DESCRIPTION

[0009] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. The accompanying drawings are primarily used to illustrate the embodiments and, in conjunction with the relevant descriptions in the specification, to explain the operating principles of the embodiments. The components in the drawings are not drawn entirely to scale, and it should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0010] Embodiment 1, as shown in FIG1 , a toilet 1 includes a toilet body, a toilet functional component arrangement area 10, a water tank at the upper rear of the toilet, a water tank cover 23 above the water tank, a sealing anti-collision rubber pad at the contact portion between the water tank cover and the water tank, a water inlet control component, a flushing water control component and other equipment are provided in the water tank, an integrated circuit control system 13 is provided above the rear of the flushing device, an atomizing nozzle 6, and the atomizing nozzle 6 sprays disinfectant water onto the inner wall of the toilet through a water pump to disinfect the toilet at regular intervals. The flushing water guide hole in the inner cavity of the toilet is a common hole for flushing water, water sliding, and an exhaust channel. The exhaust 15 flows from the flushing hole 24 and the sliding hole 21 to exhaust air through the back wall directly below the flushing control component and upward, as shown by the exhaust flow direction mark line 15, and the flushing water flows as shown in 12 As shown, the sliding-aiding hole and the flushing hole are located on the same horizontal line of the inner wall, the sliding-aiding hole is located between the flushing holes, the sliding-aiding holes and the flushing holes are distributed below the flushing water guide hole, and are distributed in the front, back, left and right of the inner wall. The comprehensive flow of the number of openings and the opening diameter is equal to or less than the incoming water flow. The opening angle of the front section is downward and backward, the middle front section is tilted downward and backward, the middle section is downward, and the rear section is tilted downward and forward. The inner cavity flushing guide hole is divided into a front section 32, a middle section 5, and a rear section 8. The diameter of the flushing holes at these three sections will determine the opening diameter according to the water volume required in different areas. The water flow rate is based on the front being large, the middle being small, and the rear section being approximately larger than the middle section. In this way, the flushing water is concentrated in one direction to flush the feces falling area, so as to reduce the amount of flushing water used to achieve the best flushing effect of the inner wall. The toilet's front wall is elevated to reduce the height of feces, reduce the force of gravity, and increase the area and slope of the feces' landing point. Feces fall into any of the following areas: the highest point 4 of the front wall, the middle section 16 of the feces landing point, or the lower section 17 of the feces landing point. Assisted by the flowing water, feces eventually slide down to the trap storage area 18, where the upper portion of the lower section 17 is roughly aligned with the rear edge of the toilet seat. The toilet's rear wall 9 has been moved back, and the trap 18 and siphon 14 have been moved back with it. This provides space for feces to fall directly into the trap storage area. The sewage outlet 22 is located below the trap storage area 18. The distance between the sewage outlet 22 and the wall varies, with typical distances ranging from 300 mm to 650 mm.

[0011] Embodiment 2, as shown in FIG2 , is a toilet 1 including a toilet body, the toilet being provided with a tissue storage area 26 , a take-out opening 31 being provided below the tissue storage area 26 for conveniently extracting tissues from the tissue storage area 26 , and a hollow space 27 being provided below the tissue storage area 26 , the bottom of the hollow space 27 being higher inside and lower outside into a sloped shape for facilitating the outflow of accumulated water in the hollow space 27 from the drain outlet 25 of the storage area, the hollow space 27 being convenient for extracting items and also for placing small items. The rear of the toilet bowl is equipped with a water retaining trough 28 and a diversion channel 11. The water retaining trough 28 intercepts the skid-inducing water discharged from the water tank. The water flows through the water retaining trough outlet 96 to the watershed 97, where it splits into two streams and flows into the diversion channel 98. The water from the diversion channel 98 flows into the diversion channel 11. The width and depth of the water retaining trough outlet 96 are slightly larger than the incoming water volume, and the diversion channel 98 has a capacity that is half that of the water retaining trough outlet 96. The skid-inducing water flows through the diversion channel 11 to the skid-inducing hole 21 and flows toward the toilet bowl interior. An atomizing nozzle 6 is installed below the toilet lid. It is connected to the water pump via a hose and sprays disinfectant onto the toilet bowl interior according to a programmed program.

[0012] Embodiment 3, referring to FIG3 , a toilet 1 includes a toilet body, a square exhaust channel 48 of the toilet, a water tank, a paper towel storage area, a hollow space below the paper towel storage area, a barrier dam 30 at the lower corner of the hollow space, and a water tank cover above the paper towel storage area. Because the paper towel storage area needs to be moisture-proof and for adding paper towels, the toilet tank cover will be opened frequently. Therefore, the water tank cover will be made of plastic or ceramic and equipped with a sealed anti-collision plastic pad at the junction of the cover and the water tank. The current bathroom area is relatively small, and the facilities and equipment are arranged a bit compactly. The shower and toilet are basically in the same area. The splashing bath water and water vapor during bathing will wet the paper towels placed in the bathroom, and the paper towels placed or hung in the bathroom also appear to be rather messy. The toilet has a paper towel storage function that will solve the above problems. Based on the conceptual framework of the present invention, the paper towel storage function will also be applied to the combination of squat toilets and wall-mounted water tanks; under the water tank cover is an integrated circuit control system 13, the integrated circuit control system 13 Between the paper towel storage area is a water pump 47, and there is an exhaust channel at the rear lower part of the integrated circuit control system. The exhaust channel is from the inner cavity through the back wall just below the flushing water control component to the back of the toilet 48, and is connected to the exhaust fan 45 upward to the right and downward. The principle of the exhaust channel going upward is to prevent the flushing water from backflowing and affecting the normal operation of the exhaust fan 45. The exhaust direction can be shown in the exhaust flow direction identification line 15. The exhaust fan 45 is connected to the exhaust hose, and the exhaust hose interface 49 is connected to other pre-buried pipe interfaces to discharge the excrement odor to the outside.

[0013] Example 4, as shown in Figure 4, a toilet 1 includes a toilet body, a water tank water level marking line 70, an overflow flow direction marking line 39, a water skiing flow direction marking line 69, a flushing water guide hole 29, a paper towel storage area 26, and a take-out port 31 below the paper towel storage area 26. The take-out port 31 is rectangular in shape, and there is a hollow space below the take-out port. The lower left corner of the hollow space is a dam 30, and the bottom of the hollow space is higher inside and lower outside, forming a slope. The water tank includes a water inlet control component 33 and a flushing water electrical control component 72. The flushing water can be controlled by the electrical control component 72 or by a manual button on the top. The flushing water control component 34 is integrated with the water tank overflow and water skiing common pipe 42. A support base 43 is provided under the common pipe 42, and a common head 100 is provided on the common pipe 42. The top of the common head 100 is provided with a water skiing interface 35. Next to the water skiing interface 35 are a rotating shaft 36, a connecting arm 38, and a float 40. The common head 100 is composed of the connecting arm 38, the float 40, the overflow port cover 37, the rotating shaft 36, the water skiing interface 35, the support arm 44, the overflow port sealing gasket 41, and the overflow water and water skiing common pipe 42. When the water level mark 70 of the water tank is too high, the float 40 is lifted by the water due to the principle of increased buoyancy as the water level increases, and the rotating shaft 36 is driven by the float 40. Rotation will automatically open the overflow cover 37, allowing excess water to be discharged into the toilet cavity through the overflow and skid-aiding common pipe 42; the toilet cavity is provided with a flushing water guide hole 29, and there is a skid-aiding water diversion guide groove 11 in the flushing water guide hole 29, and the upper end of the skid-aiding water diversion guide groove 11 is parallel to the bottom of the flushing water guide hole 29, so that the skid-aiding water will first flow along the diversion guide groove 11 to the skid-aiding hole 21 and out; the flushing water volume is large, and when flushing, the water will flow out through the flushing hole 24 and the skid-aiding hole 21, so in order to flush the inner wall of the toilet, especially the feces falling area, the diameter and angle of the opening will be adjusted at different sections to focus on flushing the inner wall of the feces falling area, so the opening angle of the front section flushing hole 24 is downward and backward, and the opening angle of the middle front section flushing hole 24 is downward and backward, which can be seen in Figures 1 and 2 for details.

[0014] Example 5, referring to Figure 5, a toilet 1 includes a toilet body, a flushing hole 29, a flushing water flow direction identification line 12, a vertical embedded pipe 79, an exhaust flow direction identification line 15, and a drain valve 51. Because the drain valve 51 is located at the lowest point of the leakage part of the exhaust (vertical and horizontal) embedded pipe joint, the condensed water generated inside the exhaust pipe will be discharged regularly from the drain valve 51. As shown in the figure, there are two ways to connect the toilet exhaust; the exhaust channel in the inner cavity of the toilet is connected to the exhaust machine to reach the hose interface 49, the hose interface 49 is connected to the embedded pipe joint 50, the embedded pipe joint 50 is connected to the vertical embedded pipe 79 and connected to the embedded pipe joint 55, the embedded pipe joint 55 is connected to the exhaust pipe interface 56, the exhaust pipe interface 56 and the ventilation fan interface 57 are connected to the exhaust hole 58 on the top of the bathroom through the three-way pipe fitting 77 to discharge the odor to the outside. If the site conditions allow, the lower hose interface 49 is directly inserted into the hole 52 of the wall drain indoors, and the odor is discharged to the outside through the hole to the outdoor hole 53 of the wall drain.

[0015] Example 6, as shown in Figure 6, includes a toilet body, a (square or round) embedded pipe 54, and an embedded pipe joint 50. One end of the embedded pipe joint 50 is connected to the hose interface, and the other end is connected to the horizontal embedded pipe. The horizontal embedded pipe is embedded along the wall to the position of the main sewage pipe and is connected to the (square or round) embedded pipe 54 through a pipe joint. The (square or round) embedded pipe 54 is connected to the exhaust pipe interface 56 through the embedded pipe joint 55. The exhaust pipe interface 56 and the ventilation fan interface 57 are connected to the exhaust hole 58 on the top of the toilet through a three-way pipe fitting to discharge the odor to the outside. Due to the limited distance between the main sewage pipe and the wall, the embedded pipe needs to be embedded close to the main sewage pipe. In order to create a perfect effect using limited space, square pipes or round pipes will be selectively used according to the on-site conditions when the pipes are embedded.

[0016] Embodiment 7, as shown in FIG7 , includes a squat toilet 2, a wall-mounted water tank 3, an integrated circuit control system 13, a water pump 47, a water inlet control component 33, a special-shaped exhaust pipe fitting 90, and a flushing water electric control component 72. The flushing water can be controlled by the electric control component 72 or by a manual button on the top. The flushing water control component 34 is integrated with the water tank overflow and water skiing common pipe 42. A support base 43 is provided under the common pipe 42. A common head 100 is provided on the common pipe 42. A water skiing interface 35 is provided at the top of the common head 100. A float 40, a connecting arm 38, and a rotating shaft 36 are provided next to the water skiing interface 35. The common head 100 is composed of the connecting arm 38, the float 40, the overflow port cover 37, the rotating shaft 36, the water skiing interface 35, the support arm 44, the overflow port sealing gasket 41, and the overflow channel. The float 40 is located at the water level mark 70 of the water tank. When the water level is too high, due to the principle of increased buoyancy caused by the rising water level, the float 40 is lifted by the water, driving the rotating shaft 36 to rotate, automatically opening the overflow cover 37, allowing excess water to drain into the toilet bowl through the overflow common pipe 42. A wall-mounted water tank inlet pipe connection 84 is located on one side of the water tank. This connection is elevated to provide space for the exhaust fan 45 when it is installed on the left side. The exhaust fan 45 can be selectively rotated to the left or right according to site requirements. The angle valve 87 and the wall-mounted indoor hole 52 also adjust the position of the exhaust fan 45 according to the installation location. The lower end of the flush control 34 is connected to the water tank height adjustment connector 85. The water tank height adjustment connector 85 is inserted from top to bottom into the common pipe connection upper port 86. The length of the pipe inserted between 85 and 86 is used to adjust the height difference caused by the installation of floor tiles. The middle diameter of the common pipe 89 is larger than the upper and lower interface diameters. This is because when the flushing water passes through 85 and reaches the bottom of the common pipe 89, the impact force generated by the water flow from top to bottom and the expansion of the air in the pipe will cause backflow and affect the normal operation of the exhaust machine 45. The capacity of the common pipe needs to fully accommodate the expansion and explosive force generated by the flushing water when it passes through, and control the backflow water level without affecting the safe operation of the exhaust machine 45. The capacity of the common pipe is determined by the common pipe diameter and the common pipe height.The exhaust channel of the squat toilet 2 is the flushing hole and the sliding hole to extract air through the flushing water guide hole, the square to round special-shaped pipe fitting 88, the common pipe 89, the exhaust pipe special-shaped pipe fitting 90 and the exhaust machine for exhaust. There are three types of exhaust channels; the exhaust passes through the exhaust machine to reach the hose interface 49, the hose interface 49 is connected to the embedded pipe joint 50, the vertical embedded pipe 79, the embedded pipe joint 55, and the pipe joint 56. The pipe joint 56 is connected to the ventilation fan interface 57 through a three-way pipe fitting and the exhaust hole 58 on the top of the toilet to discharge the odor to the outside. If the site conditions permit, the hose interface 49 is inserted into the indoor hole 52 of the wall and reaches the outdoor hole 53 of the wall through the hole to discharge the odor to the outside. The exhaust hose interface 49 is connected to the embedded pipe interface 50, the embedded pipe interface 50 is connected to the horizontal embedded pipe, the horizontal embedded pipe is embedded along the wall to the main sewage pipe position and is connected to the square or round embedded pipe 54 through the pipe joint. The embedded pipe 54 The pre-buried pipe joint 55 connects to the top exhaust pipe interface 56. The exhaust pipe interface 56 and the ventilation fan interface 57 are connected to the top exhaust vent 58 of the bathroom via a tee fitting, discharging odors outdoors. The pre-buried pipe joint 50 also has a drain valve similar to drain valve 51. The water tank is equipped with an integrated circuit control system 13, flush water electrical control 72, water pump 47, control buttons 91, and sensor 92. These electronic devices are interconnected to enable voice, button, and remote control of the product. The water tank pipes are marked with exhaust flow direction lines 15, water ski flow direction lines 69, overflow flow direction lines 39, and flush water flow direction lines 12. To provide more options for mounting and fixing the water tank and water tank shell, the water tank and water tank shell can be designed as either a single unit or a separate unit. Figure 7A is an enlarged view of the structure of Figure 7.

[0017] Example 8, as shown in FIG8 , includes a water tank water level marking line 70 and a concealed water tank 59. The concealed water tank is rectangular and no more than 300 mm in height. The water tank includes a water inlet control unit 33, a flush water electrical control unit 72, and a flush water control unit 34 integrated with a common pipe 42 for water tank overflow and water skiing. The common pipe 42 has a support base 43 below it and a common head 100 on it. The common head 100 has a water skiing interface hole 35 at the top, and a float 40 and a rotating shaft 36 next to 35. The common head 100 is composed of a connecting arm 38, a float 40, an overflow cover 37, a rotating shaft 36, a water skiing interface 35, a support arm 44, an overflow sealing gasket 41, and an overflow pipe. When the water tank water level marking line 70 is too high, the float 40 is lifted by the water due to the principle of increased buoyancy as the water level increases, driving the rotating shaft 36. Rotating this automatically opens the overflow cover 37, allowing excess water to drain into the toilet bowl through the overflow pipe 42. The system includes tank mounting bases 71, located on the left and right sides of the tank against the wall and underneath. Two additional bases are located at the upper front corners of the left and right sides of the tank. Overflow water flows toward the marking line 39, while flush water flows toward the marking line 12.

[0018] Example 9, as shown in Figure 9, the squat toilet 2 is connected to the square-to-round special-shaped pipe fitting 88 and the (square or round) embedded pipe 54. The (square or round) embedded pipe 54 is embedded next to the main sewage pipe in the bathroom. The lower end of the (square or round) embedded pipe 54 is connected to the square-to-round special-shaped pipe fitting 88 and the squat pit rear connection port 60 under the floor tile through a joint. The upper end of the embedded pipe 54 is connected to the exhaust pipe interface 56 through a joint. The pipe interface 56 is connected to the bottom connection port of the water tank and reaches the hidden water tank exhaust connection port 74 through the exhaust fan and is connected to the three-way interface 75. The ventilation fan interface 57 is connected to the three-way interface 76. The three-way interface 78 is connected to the exhaust hole 58 on the top of the bathroom to discharge the odor to the outside. Since the distance between the main sewage pipe and the wall is limited, in order to create a perfect effect by utilizing the limited space, square pipes or round pipes will be selectively used according to the on-site conditions when pre-buried pipes.

[0019] Example 10, as shown in Figure 10, a squat toilet includes a squat toilet body 2, a squat pit rear connection port sealing ring 65, a water trap dam 19, and a squat pit rear connection port 60. In this way, the squat pit rear connection port 60 and the flushing water guide hole are on the same horizontal line. The guide hole height becomes shorter, the flushing horizontal flow is reduced, the water flow pressure will increase, and the water volume will be evenly distributed. The inner cavity flushing water guide hole 29 is a common hole for flushing water, skiing water, and exhaust. The skiing flushing hole 103 and the skiing hole 21 are located below the flushing water guide hole. The skiing hole 21 is located between the flushing hole 24 and the flushing hole 24. The skiing hole 21 and the flushing hole 24 are distributed on the front, back, left, and right sides of the inner wall. The skiing hole 21 and the flushing hole 24 are located below the flushing water guide hole. The combined flow of the number of openings and the opening diameter is equal to or less than the incoming water flow. The opening angle of the front section is downward in sequence, the middle front section is tilted downward and backward, the middle section is downward, and the rear section is downward and forward; the inner cavity flushing guide hole is divided into a front section 32, a middle section 5, and a rear section 8. The diameter of the flushing holes at these three sections will be determined according to the amount of water required in different areas. The water flow rate is based on the front being large, the middle being small, and the rear section being approximately larger than the middle section. In this way, the flushing water will concentrate the water in one direction to flush the area where feces falls, so as to reduce the amount of flushing water used to achieve the best flushing effect of the inner wall. The front wall of the squat toilet is elevated to reduce the height of feces, reduce the force of gravity, increase the landing area and the slope of feces, and lower the height of the trap water storage area 18. This provides design and layout space for the trap to retreat and the siphon effect required by the sewage pipe. Feces fall to any of the following areas: the highest point 4 of the front wall, the middle section 16 of the feces landing point, and the lower section 17 of the feces landing point. Feces slides down to the trap water storage area 18 with the help of water sliding. The rear wall 9 is convex to the squat toilet. The raised point 7 on the toilet's rear wall shifts the trap water storage area 18 backward to provide space for feces to fall directly into the trap water storage area. Squat toilet outlet dimensions are primarily categorized into two types: front and rear. The distance between the front sewage outlet 22 is between 400-700mm, while the distance between the rear sewage outlet 22 is between 250-500mm. The drawings provided in this invention illustrate front sewage. Rear sewage requires relocating the rear connection port 60 to the front of the squat toilet, which in turn changes other squat toilet functions. A sliding flushing hole 103 extends downward from the highest point 4 on the squat toilet's front wall. The water flowing from this flushing hole 103, along with other flushing holes 24 on the inner wall, creates a high-flow flushing stream that instantly covers the trap, flushing the raised point and lower section of the squat toilet's rear wall and removing feces.

[0020] Example 11, as shown in FIG. 11 , includes a concealed water tank 59, a squat toilet 2, a flushing water control 72 in the water tank, a water tank water level indicator 70, a flushing water flow direction indicator 12, a concealed water tank flushing water inlet flow direction indicator 81, an exhaust flow direction indicator 15, a concealed water tank water skiing aid indicator 80, a concealed water tank water skiing aid outlet 83, an exhaust fan 45, a concealed water tank flushing water inlet flow direction indicator 81, a concealed water tank water skiing aid outlet 74, a vertical pre-buried pipe 79, the squat toilet 2 connected to the vertical pre-buried pipe 79, and the vertical pre-buried pipe 79 connected to the concealed water tank 59. The water tank water skiing aid outlet is located behind the water tank water tank exhaust pipe connection 74. The water skiing aid outlet is connected to the water outlet and passes downward through the exhaust fan 45. It is connected to the water tank flushing pipe just below, and the water tank flushing air inlet is located above the water skiing outlet. One end of the water tank air inlet pipe 82 is connected to the water tank flushing air inlet and the other end extends into the exhaust pipe, so that the water vapor generated by the water tank is discharged outdoors together with the gas discharged by the exhaust fan through the pipe.

[0021] Example 12, as shown in Figure 12, includes a squat toilet 2, a concealed water tank 59, a vertical pre-buried pipe 79, an integrated circuit control system 13, an electronically controlled water valve 46, an exhaust fan 45, a concealed water tank flushing water inlet 73, an exhaust flow direction indicator line 15, and a water skiing flow direction indicator line 80. The water skiing flow direction is downward through the outlet, then to the left through the electronically controlled water valve 46, to the exhaust pipe, and then downward. The exhaust channel is connected between the squat toilet and the vertical pre-buried pipe 79. The vertical pre-buried pipe 79 is connected to the water tank 59 interface and upwardly connected to the exhaust fan 45. The exhaust fan 45 is connected to the water tank exhaust pipe interface 74. The concealed water tank exhaust connection port 74 is connected to the three-way interface 75. The ventilation fan interface 57 is connected to the three-way interface 76. The three-way interface 78 is connected to the exhaust hole 58 at the top of the toilet to discharge odors to the outside. The integrated circuit control system 13 and the electronically controlled water valve 46, the flushing water and electric control unit 72, and the exhaust fan 45 are connected to the wall key control device and the remote control device through pre-buried lines to realize remote control, keystrokes, voice control and other methods of related electronic equipment in the water tank.

[0022] Example 13, as shown in Figure 13, includes a top view of two shapes of pipes, a vertical embedded pipe 79 and a square embedded pipe 54, an exhaust pipe wall 61, a damping plate 63, and sound insulation cotton 64. The outer wall of the pipe is wrapped with a damping plate and sound insulation cotton or sound-absorbing cotton. The purpose is to generate water flow sound when flushing water passes through the pipe, and the pipe is subjected to silencing and noise reduction treatment to reduce the noise generated when flushing water passes through the pipe.

[0023] Example 14, see Figure 14; it includes a squat toilet 2, the inner cavity is provided with a flushing water guide hole 29, and the flushing water guide hole is provided with a sliding water diversion groove 11, the upper end of the sliding water diversion groove 11 is parallel to the bottom of the flushing water guide hole, so that the sliding water will flow along the sliding water diversion groove 11 to the sliding hole 21 and out. The amount of flushing water is large. During flushing, the water will flow out through the flushing hole 24 and the sliding hole 21 to flush the inner wall. Therefore, in order to flush the inner wall of the toilet clean, especially to flush the feces hanging on the wall, it is necessary to adjust the opening diameter and angle of the flushing hole 24 and the sliding hole 21 at different sections to achieve the purpose of focusing on flushing the inner wall of the area where excrement falls. Therefore, the opening angle of the front section of the flushing hole 24 and the sliding hole 21 is downward and backward, and the opening angle of the middle section is downward and backward, so that the flushing water forms a collective and flushes the feces falling area in the same direction.

[0024] Embodiments 15 and 16, as shown in Figures 15 and 16, include a squat toilet flushing exhaust pipe connection port 68 and an exhaust pipe interface 62. Figure 15 shows the cross-sectional shape of the squat toilet flushing exhaust connection port 68 and a connection method with the exhaust pipe interface 62. Figure 16 is a top view and a side view of the connecting pipe.

[0025] Example 17, as shown in FIG. 17 , includes a squat toilet 2 and the shape of a rear connection port 60 of the squat toilet.

[0026] Example 18, as shown in Figure 18, includes a water retaining trough 28, a water retaining trough outlet 96, a watershed 97, a diversion trough 98, and a water-sliding diversion guide trough 11. Figure 18 illustrates the structure of the water-sliding guide trough in the inner cavity of a squat toilet.

[0027] Example 19, as shown in Figure 19, includes a wall-mounted water tank 3, a vertical pre-buried pipe 79, a sensor 92, a hidden water tank 59 and a vertical pre-buried pipe 79 including a squat toilet and a connection structure diagram of the wall-mounted water tank 3.

[0028] Example 20, as shown in Figure 20, includes a sensor 92, a control button 91, and a front view and a side view of the wall-mounted water tank 3. In the side view, the height difference between the lower corner 94 of the water tank shell and the rear lower corner 93 of the water tank shell is 1mm-12mm.

[0029] Example 21, as shown in FIG. 21 , shows a toilet A102 comprising a toilet body. The inner front wall is elevated to a certain degree. To reduce the height of excrement, reduce the force of gravity, and increase the area and slope of feces, the height of the trap reservoir 18 is lowered. The setback of the trap reservoir provides space for the structural integrity of the siphon pipe and prevents feces from falling directly into the trap reservoir. The siphon pipe 14 is located below the inner front wall. If feces falls into any of the following areas: the highest point 4 of the front wall, the middle section 16 of the feces landing point, or the lower section 17 of the feces landing point, feces will slide down into the trap reservoir 18 with the aid of water sliding. The rear wall 9 protrudes forward to the rear wall convex point 7 of the squat toilet, which is approximately lower than the highest point 4 of the front wall. Other technical features are similar to those described above for toilet 1. See Examples 1, 2, 3, 4, and 5 for details.

[0030] Currently, bathrooms are basically only equipped with a sewage pipe and a sewage vent pipe, and there is no separate bathroom ventilation exhaust pipe (hereinafter referred to as the main exhaust pipe). The existing exhaust outlet is mainly completed by the exhaust hole 58 on the top of the bathroom. With the development of society and the improvement of living standards, future bathrooms will definitely have a separate main exhaust pipe in the design and construction standards. In order to make the building appearance more perfect, the exhaust hole 58 on the top of the bathroom will not be opened at that time. Therefore, the exhaust pipe of the present invention will also be connected to the separate main exhaust pipe of the bathroom to discharge the odor to the outside. At present, the noise of ventilation and exhaust equipment in the bathroom is generally high, reaching as high as about 65 decibels, and there is no good quiet environment when using the bathroom; the product of the present invention will adopt high-efficiency silent equipment, and implement noise reduction and noise reduction for noise-generating facilities and equipment to control the noise within 35 decibels. The existing drawings of the present invention show that the exhaust fan and the product are designed as an integrated whole. Under the design concept and facility layout of the present invention, the exhaust fan can also be separated into an independent device and installed in the ceiling, and connected to other facilities and equipment, so that the ventilation function of the ventilation fan can be replaced. The exhaust fan can use the air inlet of the ventilation fan, or a separate air inlet can be installed on the gusset plate for exhaust, which is more conducive to upgrading, expanding and expanding the performance of the product.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Those skilled in the art should understand that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should fall within the scope of protection of the present invention.
