Technical field

The invention relates to a sanitary ware, that is, a self-cleaning, non-blocking and odorless toilet.

Background technique

Toilets include squatting pans and toilets, which are living utensils for receiving and discharging human feces. The main body of the existing toilet is a container-shaped toilet, which may be covered or uncovered. The bottom of the tank is provided with a discharge port, and the inner side of the upper port is provided with a water spray hole. Most of the toilets are located in the room, very close to the place where people live or work, so the peculiar smell of feces and other pollutants must be eliminated in time. However, it only relies on the height difference of the water storage tank and the gravity of the water, without additional pressure, the pressure is very small, and the ability to decontaminate and deodorize is poor. In addition, this kind of device can only be flushed after the person has discharged the feces, and the peculiar smell during the defecation process will spread around. Although many toilets are equipped with exhaust fans, the toilets have a large space and the exhaust fans are far away from the toilet, which makes it difficult to exhaust the odor in time. If a larger power exhaust fan is used, the power consumption is large and the use cost is high. Especially when the exhaust fan is stopped, it is difficult to prevent the airflow from going backward. The odor in the adjacent room will also enter the room through the exhaust fan. Therefore, many users keep the exhaust fan closed. The odor of their own excrement can only be discharged by opening the window and the door. , People must endure the pollution during the discharge process. Due to the insufficient flushing pressure, the discharge port of the existing toilet is easily blocked, requiring additional equipment or even professionals to clear it, which is very troublesome. In addition, the existing toilet is also a breeding place for bacteria and viruses, and it is difficult to achieve the purpose of sterilization and disinfection only by washing with tap water at room temperature. It can be seen that the existing toilets are difficult to adapt to the requirements of the rapid improvement of people's living standards and are in urgent need of improvement.

detailed description

The general idea of the present invention is to install a cleaning pipe with a booster pump 10 on the toilet 1 to perform high-pressure cleaning on the toilet, so as to achieve the goal of no pollution, no smell and no blockage. Five embodiments are described below with reference to the drawings.

The first embodiment: as shown in Figure 1, this kind of pollution-free and odor-free long toilet includes squatting or sitting. The example in the figure is a type of toilet, which has a container-shaped toilet 1. Both the inside and the bottom of the toilet 1 are provided with an S-shaped discharge port. A water tank 6 is provided on the outside and above the toilet 1, and a water spray hole 2 is provided in the toilet. The water tank 6 communicates with the water spray hole 2 through a water pipe 7. Its characteristic is: the toilet is provided with a cleaning pipe 8 with a booster pump 10. The booster pump 10 here covers a wide range, including all power devices capable of pushing fluid media. The cleaning pipe 8 in this example is also a kind of negative pressure pipe 9. One end of the negative pressure pipe 9 extends into the toilet 1, and the other end extends out of the outside to reach a position where discharge is allowed. The negative pressure pipe 9 is equipped with a negative pressure pump. 11. Obviously, the negative pressure pump 11 mentioned here should include various air pumps, induced draft fans, exhaust fans and other equipment.

When in use, the negative pressure pump 11 is first turned on to make the inside of the bowl 1 in a negative pressure state, and the peculiar smell of feces is sucked into the negative pressure pipe and discharged. Compared with the existing toilet installation exhaust fan, the space that needs to be cleaned is greatly reduced, no high-power negative pressure pump is required, less electrodes are used, and the negative pressure port is directly opposite to the point where the odor occurs, the odor is completely absorbed, and there should be no odor in the room diffusion.

After use, it is best to turn off the negative pressure pump first, and then press the button of the water tank. In this way, the water sprayed from the water tank will not be sucked into the negative pressure pipe. For this reason, the reverse linkage switch shown in Figure 2 is recommended here. The switch A in the figure represents the switch of the water tank, and B represents the switch of the negative pressure pump. While pressing switch A, the switch of the negative pressure pump is turned off, and vice versa.

The above process is preferably controlled by an automatic control device, such as a human body induction circuit. When a person approaches the toilet, the negative pressure pump is turned on; the negative pressure pump is turned off when the defecation ends, and the water is flushed.

Need to explain: the water mentioned here is equivalent to various cleaning fluids, cleaning solvents and other liquids.

The second embodiment: as shown in Figure 3, a water delivery ring 3 is provided in the toilet wall around the upper mouth of the toilet 1, and the water delivery ring 3 is provided with a plurality of spray holes 2 inside the toilet. 3 is connected to the water tank 6 and the negative pressure pipe 9 through the water pipe 7 outwardly. [0024] Obviously, on the basis of the first embodiment, the negative pressure pipe 9 and the water pipe 7 are combined into one, which makes the structure more compact.

The method of use is the same as that of the first embodiment, and it is better to optimize the reverse linkage of the switch of the water tank and the switch of the negative pressure pump. And it is recommended to use an automatic control device for control, such as a human body sensing circuit, when a person approaches the toilet, the negative pressure pump is turned on; the negative pressure pump is turned off after defecation, and the water is flushed.

The third embodiment: an improvement on the basis of the previous embodiment. As shown in Figure 4, the inner end of the negative pressure pipe 9 is connected with the water delivery ring 3. The negative pressure pipe 9 is equipped with one or more of the water pipe 7, the hot water pipe 12, the steam pipe 13, and the hot air pipe 14. The installed water pipe 7, hot water pipe 12, steam pipe 13, and hot air pipe 14 are equipped with a booster pump 10.

The booster pump 10 here can be installed on each pipe separately. In the case where each pipe is equipped with a valve 15, multiple pipes can share one booster pump 10.

The installed water pipe 7, hot water pipe 12, steam pipe 13, the booster pump 10 on the hot air pipe 14 and the negative pressure pump switch on the negative pressure pipe 9 are preferably set as reverse linkage switches.

Usage: When a person approaches the toilet, the negative pressure pump is turned on; the defecation is finished, the negative pressure pump is turned off, and each tube is turned on in turn at the same time, and the high pressure fluid is formed to impact the feces through the booster pump. Taking the installation of the water pipe 7, the hot water pipe 12, the steam pipe 13, and the hot air pipe 14 as an example, the water pipe is closed after the high-pressure water flushing, and the hot water pipe 12 works to release hot water for a second flush. Subsequently, the hot water pipe 12 is closed and the steam pipe 13 is opened to release steam for sterilization. Then close the steam pipe and open the hot air pipe 14 for drying. In this way, dirt and peculiar smell can be completely removed, and it can be kept clean for a long time.

The above process can be operated manually, or the booster pump switch of the water pipe 7, the hot water pipe 12, the steam pipe 13, and the hot air pipe 14 and the negative pressure pump switch of the negative pressure pipe can be set as reverse linkage switches. It is best to use an automatic control device as shown in Figure 5 for control. The automatic control device mentioned here can be controlled by a program control device or an intelligent control device, and a working program can be compiled in accordance with the aforementioned use mode.

Need to explain: the water or hot water mentioned here is equivalent to various cleaning fluids, cleaning agents and other liquids. The steam mentioned here is equivalent to various other gas substances that can be used for sterilization, disinfection and drying.

Fourth embodiment: As shown in Figure 6, on the basis of the third embodiment, the water pipe 7, the hot water pipe 12, the steam pipe 13, and the three pipes are combined into one, sharing a booster pump 10, and Install electric heater 16. The electric heater used here can change the normal temperature liquid into high temperature liquid or gas as needed. The water source can be the same room temperature water, and when passing through the pipe, it is heated by the electric heater 16 to form hot water and steam respectively. Need to explain: The water mentioned here is equivalent to various cleaning liquids, cleaning solvents and other liquids. The steam mentioned here is equivalent to various other gas substances that can be used for sterilization, disinfection and drying.

Fifth embodiment: As shown in Figure 7, the cleaning pipe (8) used here is a positive pressure pipe (17) equipped with a booster pump (10), one end of which is inserted under the toilet lid. The toilet lid 5 is a lid with a double-layer hollow structure. It can be seen in conjunction with Fig. 8 and Fig. 9 that a cover bottom plate 20 is installed on the inner side of the toilet cover 5, and a plurality of spray holes 21 are opened on the cover bottom plate 20. Between the bowl cover 5 and the cover bottom plate 20 is a cover inner cavity 19, and a positive pressure tube 17 is inserted into the cover inner cavity 19. There are many ways for the positive pressure tube 17 to enter the inner cavity 19 of the lid. The example in the figure is to enter from the shaft 24 of the toilet lid. The bowl cover shaft is a hollow tube, which can be fixed or rotating. It can be seen from FIG. 10 that at the position where it enters the inner cavity 19 of the lid, a shaft side hole 25 is opened in the direction of the cavity, so that the fluid medium can enter the inner cavity 19 without affecting the turning of the toilet lid.

In addition, the rotation of the toilet cover 5 can be manually operated by a person, or it can be driven by a micro motor. The advantage of motor drive is that it can be automated and intelligent.

It can be seen from Figure 11 that the positive pressure pipe 17 is connected to one or more of the water pipe 7, the hot water pipe 12, the steam pipe 13, and the hot air pipe 14. The water pipe 7, the hot water pipe 12, the steam pipe 13, and the heat pipe The air pipe 14 is equipped with a valve 15 and a booster pump 10. If the booster pump 10 has the function of a valve, only the booster pump is enough. If a booster pump 10 is used for multiple pipes, valves 15 need to be installed on each pipe. In order to achieve automation or intelligence, the valve 15 and the booster pump 10 here should be connected with automation or intelligent control circuits or devices. Various fluid media have their sources, and the source structures are also diverse. It is recommended in FIG. 11 to use multiple media tanks 26, such as water, hot water, steam, and hot air, each with its own media tank 26.

Of course, the medium tank for water, hot water, and steam can also be a water medium tank 26. The water runs under the push of the booster pump 10 and is heated to hot water or when it passes through the electric heater 16 on the positive pressure pipe 17. The steam and hot air pipe can turn the air into hot air through the electric heater 16. In this way, as shown in Figure 12, the water pipe 7, the hot water pipe 12, and the steam pipe 13 are combined into a single pipe, which shares a booster pump (10) and an electric heater (16) with the hot air pipe (14).

When in use, a person approaches the toilet 1, opens the toilet lid 5, and the negative pressure pump 11 of the negative pressure pipe 9 starts to work. When a person defecates, the urinal is in a negative pressure state, and all odors are taken away by the negative pressure tube 9. After defecation, close the toilet cover 5, the negative pressure pipe 9 stops working, the booster pump 10 starts, and high-pressure water is shot down from the spray hole 21; then, the high-pressure water pipe valve stops, the hot water pipe 12 opens, and hot water flows from the spray hole 21 is shot down; then the hot water stops, the steam pipe 13 starts, and the steam is shot down from the spray hole 21; finally, hot air is released to complete the cleaning, disinfection and drying operation.

This kind of toilet cover 5 should be made into a member with pressure resistance. A sealing ring 22 is provided on the lower side and a lock 18 is provided on the outer periphery. After being closed, the lock 18 is locked on the chuck 23 to form a seal with the toilet below. Space. This method is not only suitable for flushing and disinfecting the toilet, but also suitable for preventing or eliminating blockage. When the bowl is about to be blocked or has been blocked, close the bowl cover 5 and launch high-pressure water to open the drain forcibly.

Obviously, the above structure can be operated manually, or an automatic control device can be added to realize automation and intelligence. The program control or intelligent control device can be designed according to the above-mentioned working process.

Of course, the negative pressure tube 9 can also be inserted into the lid cavity 19 of the toilet lid through the toilet lid shaft, and the original toilet flushing device can also be removed to make the overall structure more compact and easy to manufacture.
