Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum toilets, and in particular relates to a flush pipe emptying antifreeze vacuum toilet. Background Art

[0002] Vacuum toilets have been widely used at home and abroad. Their application areas include various public transportation fields, including trains, long-distance buses, ships, airplanes and buildings. Vacuum toilets are a technology that integrates environmental protection and water saving, sewage collection, raw water recycling and green fertilizer making systems. It passes sewage through a vacuum pipe, adds a small amount of flushing water, and collects excrement into a pre-set vacuum sewage tank.

[0003] During the use of existing vacuum toilets, the pressure generated between the pipe and the water tank, that is, the siphon principle, is used to flush the excrement into the sewage tank. However, when the vacuum toilet is used in plateaus and other areas, the temperature difference between day and night is large, and the liquid in the flush pipe pipe is very easy to freeze, causing the flush pipe to be blocked, affecting the normal use of the toilet. Secondly, as the excrement accumulates in the sewage tank, it will continue to ferment, and a large amount of biogas will be produced during the fermentation process, which will increase the air pressure in the sewage tank. If the time is too long, the biogas will accumulate more and more, and the sewage tank will not be able to withstand the pressure and explode, greatly reducing its safety performance. Therefore, we provide a flush pipe emptying antifreeze vacuum toilet. Utility Model Content

[0004] The utility model aims to provide a flush pipe emptying antifreeze vacuum toilet to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flush pipe emptying antifreeze vacuum toilet, comprising a sewage tank and a squat toilet, both sides of the back of the sewage tank are fixedly connected with a support frame, the top of the support frame is fixedly connected with a water tank, a group of heating resistance wires are arranged at the bottom of the inner cavity of the water tank, a fan is fixedly installed on the right side of the sewage tank, an input end of the fan is fixedly connected with an air duct, one end of the air duct is connected with a purification box, the left side of the purification box is connected with an air supply pipe, one end of the air supply pipe is connected with the top of the sewage tank, an output end of the fan is fixedly connected with an air outlet pipe, an air pressure sensor is arranged on the left side of the top of the sewage tank, the detection end of the air pressure sensor is located at the top of the inner cavity of the sewage tank, and the bottom of the squat toilet and the top of the sewage tank are connected through a sewage discharge pipe.

[0006] By adopting the above scheme, the water inside the water tank is heated by the heating resistor wire to increase the temperature of the water. When the hot water passes through the inside of the water pipe, the ice residue inside the water pipe can be melted to prevent the water pipe from being blocked during use. Secondly, the air pressure sensor and the detection head are used in combination to detect the air pressure inside the sewage tank in real time. When the air pressure is higher than the set value, the fan is started, and the gas inside the sewage tank is sucked in by the fan with the cooperation of the air guide pipe. The gas is transported to the purification box through the air guide pipe, and the gas is transported to the air outlet pipe through the purification box with the cooperation of the air guide pipe. The gas is transported to the outside through the air outlet pipe, thereby reducing the air pressure inside the sewage tank and achieving the purpose of automatic pressure relief. The movement stops after the air pressure inside the sewage tank returns to the set value, thereby preventing the pressure inside the sewage tank from being too high, thereby preventing the possibility of explosion, and improving the safety performance of the sewage tank.

[0007] As a preferred embodiment of a flush pipe-emptied antifreeze vacuum toilet, the squat toilet and the water tank are connected by a water pipe, and a No. 2 control valve and a vacuum tube are respectively provided on the surface of the water pipe, and one end of the vacuum tube extends into the interior of the water tank.

[0008] By adopting the above scheme, since the water pipe is connected with a vacuum tube, and one end of the vacuum tube extends into the interior of the water tank, the pressure generated between the vacuum tube and the water tank is used to form a siphon phenomenon. When the No. 2 control valve is turned, water flows through the water pipe to the interior of the squat toilet and flushes the excrement inside the squat toilet. No external electrical equipment is required, saving production costs.

[0009] As a preferred embodiment of a flush pipe emptying antifreeze vacuum toilet, leaking plates are provided on both sides of the interior of the purification box, and activated carbon adsorption blocks are placed on the inner sides of the leaking plates.

[0010] By adopting the above scheme, through the setting of activated carbon adsorption blocks, since activated carbon has a porous structure, when the gas containing odor passes through the activated carbon, the activated carbon can adsorb the odor in the gas in the adsorption pores of the activated carbon, preventing the gas from being directly discharged to pollute the environment, thereby achieving the purpose of purifying the air.

[0011] As a preferred embodiment of a flush pipe emptying antifreeze vacuum toilet, a water inlet is opened at the rear end of the right side of the top of the water tank, and a sealing cover is provided on the water inlet, and an observation window is provided on the front surface of the water tank.

[0012] By adopting the above scheme, the water level inside the water tank can be detected in real time through the setting of the observation window. When the water level is insufficient, it can be replenished in time to prevent the subsequent flushing work from being unable to proceed due to the low water level inside the water tank.

[0013] As a preferred embodiment of a flush pipe emptying antifreeze vacuum toilet, pedals are fixedly connected to both sides of the squat toilet, and anti-slip pads are bonded to the surfaces of the pedals.

[0014] By adopting the above solution, the anti-skid pad is provided to prevent the user from slipping when squatting, thereby preventing the user from falling.

[0015] As a preferred embodiment of a flush pipe emptying antifreeze vacuum toilet, the bottom of the left side of the water tank is connected to a water outlet pipe, and a control valve is provided on the surface of the water outlet pipe.

[0016] By adopting the above scheme, when the water tank is not in use, the water inside the water tank can be quickly discharged through the setting of the No. 1 control valve with the cooperation of the water outlet pipe.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The utility model uses a blower to suck gas inside the sewage tank in cooperation with an air duct, and the gas is transported to a purification box through an air delivery pipe. The purification box transports the gas to an air outlet pipe in cooperation with the air duct, and the gas is transported to the outside through the air outlet pipe, thereby reducing the air pressure inside the sewage tank and achieving the purpose of automatic pressure relief. The movement stops after the air pressure inside the sewage tank returns to a set value, thereby preventing the pressure inside the sewage tank from being too high, thereby preventing the possibility of explosion, and improving the safety performance of the sewage tank.

[0019] 2. The utility model heats the water inside the water tank by means of a heating resistor wire, thereby increasing the temperature of the water.

Through the setting of the activated carbon adsorption blocks, since the activated carbon has a porous structure, when the gas containing odor passes through the activated carbon, the activated carbon can adsorb the odor in the gas in the adsorption holes of the activated carbon, preventing the gas from being directly discharged to pollute the environment, thereby achieving the purpose of purifying the air. The left side of the purification box 10 is connected with an air supply pipe 11, one end of the air supply pipe 11 is connected to the top of the sewage tank 1, and the output end of the fan 7 is fixedly connected to the air outlet pipe 8. An air pressure sensor 12 is provided on the left side of the top of the sewage tank 1, and the detection end of the air pressure sensor 12 is located at the top of the inner cavity of the sewage tank 1. The bottom of the squat toilet 2 and the top of the sewage tank 1 are connected through a sewage discharge pipe 13. Figure 1 As shown, the squat toilet 2 and the water tank 4 are connected through a water pipe 14, and a No. 2 control valve and a vacuum tube 6 are respectively provided on the surface of the water pipe 14. One end of the vacuum tube 6 extends into the interior of the water tank 4. Because the vacuum tube 6 is connected to the water pipe 14, and one end of the vacuum tube 6 extends into the interior of the water tank 4, a siphon phenomenon is formed by utilizing the pressure generated between the vacuum tube 6 and the water tank 4. When the No. 2 control valve is turned, water flows through the water pipe 14 to the interior of the squat toilet 2, and flushes the excrement inside the squat toilet 2. No external electrical equipment is required, saving production costs. The water inside the water tank 4 is heated by the heating resistor 5 to increase the water temperature. When hot water passes through the interior of the water pipe 14, the ice residue inside the water pipe 14 can be flushed out. Melt to prevent the water pipe 14 from being blocked during use. Secondly, the air pressure sensor 12 and the detection head are used together to detect the air pressure inside the sewage tank 1 in real time. When the air pressure is higher than the set value, the fan 7 is started, and the gas inside the sewage tank 1 is sucked in by the fan 7 with the cooperation of the air duct 9. The gas is transported to the purification box 10 through the air duct 11. The purification box 10 transports the gas to the outlet pipe 8 with the cooperation of the air duct 9, and the gas is transported to the outside through the outlet pipe 8, thereby reducing the air pressure inside the sewage tank 1 and achieving the purpose of automatic pressure relief. The movement stops after the air pressure inside the sewage tank 1 returns to the set value, preventing the pressure inside the sewage tank 1 from being too high, thereby preventing the possibility of explosion, and improving the safety performance of the sewage tank 1.

[0025] See Figure 1As shown, a water inlet is provided at the rear end of the right side of the top of the water tank 4, and a sealing cover is provided on the water inlet. An observation window is provided on the front surface of the water tank 4. Through the setting of the observation window, the water volume inside the water tank 4 can be detected in real time. When the water volume is insufficient, it can be replenished in time to prevent the subsequent flushing work from being unable to be carried out due to the low water volume inside the water tank 4. Figure 1 As shown, pedals are fixedly connected to both sides of the squat toilet 2, and anti-skid pads are bonded to the surface of the pedals. The anti-skid pads can prevent the user from slipping when squatting, thereby preventing the user from falling. The bottom of the left side of the water tank 4 is connected to a water outlet pipe, and a control valve is provided on the surface of the water outlet pipe. When the water tank 4 is not in use, the water inside the water tank 4 can be quickly discharged with the cooperation of the water outlet pipe through the setting of the No. 1 control valve.

[0026] When in use, firstly, water is transported to the inner cavity of the water tank 4 through the water filling port on the water tank 4, and the water is submerged over the surface of the vacuum tube 6. After the water filling is completed, the sealing cover is reset, and at the same time, the water inside the water tank 4 is heated by the heating resistor 5 to increase the temperature of the water. When the squat toilet 2 is used, when it is necessary to clean the excrement inside the squat toilet 2, the No. 2 control valve on the water pipe 14 is turned to open the water pipe 14. Because the vacuum tube 6 is connected to the water pipe 14, and one end of the vacuum tube 6 extends into the water tank 4, when the water pipe 14 is opened, the pressure generated between the vacuum tube 6 and the water tank 4 is used to form a siphon phenomenon, so that the hot water inside the water tank 4 is transported to the inside of the squat toilet 2 through the water pipe 14. When the hot water passes through the inside of the water pipe 14, the ice residue inside the water pipe 14 can be melted to prevent the water pipe 14 from being used. In the process, if there is a blockage, the excrement inside the squat toilet 2 is flushed, and the excrement after flushing is transported to the sewage tank 1 through the sewage pipe 13, and the excrement is accumulated in the sewage tank 1. Finally, the air pressure sensor 12 and the detection head are used together to detect the air pressure inside the sewage tank 1 in real time. When the air pressure is higher than the set value, the fan 7 is started, and the gas inside the sewage tank 1 is sucked in by the fan 7 with the cooperation of the air duct 9. The gas is transported to the purification box 10 through the air pipe 11, and the gas is transported to the outlet pipe 8 through the purification box 10 with the cooperation of the air duct 9. The gas is transported to the outside through the outlet pipe 8, thereby reducing the air pressure inside the sewage tank 1 and achieving the purpose of automatic pressure relief. The movement stops after the air pressure inside the sewage tank 1 returns to the set value, thereby preventing the pressure inside the sewage tank 1 from being too high, thereby preventing the possibility of explosion, and improving the safety performance of the sewage tank 1.
