Description

Technical Field

[0001] The utility model relates to a dry toilet direct drainage odor-isolating device, in particular to a dry toilet direct drainage odor-isolating device and a dry type direct drainage toilet sealing device. Background Art

[0002] There is a dry toilet device with document number CN 209018593 U applied by the applicant company, which includes a toilet bowl and a discharge pipe, wherein at least two layers of upper and lower movable blocking mechanisms are arranged in the discharge pipe, and at least one natural exhaust and / or electric exhaust air exhaust pipe is led out from the chamber between the upper and lower movable blocking mechanisms, and the lower part of the discharge pipe is connected to a sewer pipe or a toilet pit. The movable blocking mechanism is an active blocking mechanism that can remain relatively closed when the discharge pipe is configured in a normal state, and can expand and discharge when it is subjected to a certain degree of impact and compression of heavy objects. The movable blocking mechanism configured in the discharge pipe can be a flexible flat tube or a flexible matching tube or a flip spoon or a flap; or a tube that is closed by material shape memory, self-elasticity, magnetic force, or gravity. The lower movable plugging mechanism is a flap or flap hinged at the lower end of the discharge pipe that can cover the lower port of the discharge pipe. The base of the flap or flap hinged to the lower end of the discharge pipe is horizontally or obliquely extended backward by a counterweight body with a weight greater than the weight of the flap or flap. However, there is still a problem that the expansion discharge movable plugging mechanism will age and reduce the recovery elasticity after long-term use, resulting in a loose closure. When the counterweight body flap or flap and the lower port of the discharge pipe are not maintained in time after long-term use, foreign objects may block the closed port, and the closure is not tight, leaking upwards and causing odor in the toilet pit. Moreover, because it has the advantages of being particularly water-saving, easy to clean, not blocked, and easier to use with fertilizer pits or cellars, it is particularly suitable for rural areas without centralized septic tank facilities. However, the direct connection between the lower discharge port and the sewer pit will cause odor to overflow, seriously affecting the air environment of the toilet. Therefore, the existing mechanical isolation cannot completely isolate odors, and it is urgently needed to innovate complete odor isolation technology. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned defects of the prior art and provide a dry-type direct drainage and odor-isolating device and a dry-type direct drainage and sealing toilet. The device and toilet can seal the lower discharge port by water seal in other standby states except the defecation state, so as to achieve normal odor isolation; the amount of water used is limited to the amount of water seal, which is a super water-saving and odor-isolating dry-type direct drainage device and toilet; on the premise of maintaining the advantages of direct drainage toilets, complete odor isolation is achieved.

[0004] To achieve the above-mentioned purpose, the utility model is a dry toilet direct drainage odor-isolating device, which is special in that a water receiving pan for accommodating sealing water is provided at the direct or extended lower discharge outlet of the dry direct discharge toilet bowl, the handle end of the water receiving pan is hinged to an axle seat mechanism, and the extended part of the handle end of the water receiving pan is provided to enable the water receiving pan to buckle upwardly with a counterweight body of the lower discharge outlet; and a water injection mechanism is provided to inject water into the water receiving pan to submerge the water level of the lower discharge outlet when the water receiving pan is in the upward buckled state after defecation. In this way, before going to the toilet, in the waiting state, the counterweight body will buckle the water receiving tray upward to close the lower outlet through the lever action, and the fixed amount or fixed water level water injected by the water injection mechanism will also submerge the lower outlet, thereby playing the role of storing water and sealing the lower outlet to isolate odor; when going to the toilet, the feces and urine that fall into the dry direct discharge toilet fall to the water receiving tray, and under the impact force and gravity, the water receiving tray will tilt downward, so that the feces and urine will fall and be discharged; the water receiving tray for discharging feces and urine will naturally buckle upward to close the lower outlet again under the back pressure of the counterweight body due to the lighter weight, and the water injection mechanism will add water to the fixed amount of water that submerges the lower outlet or add water to the fixed water level that submerges the lower outlet. It should be noted that the fixed amount of water filling is achieved by a manual control valve for quantitative drainage or a quantitative drainage electric control valve that senses the human body leaving and is inductively linked. Fixed water level filling is a water injection pipe or water injection cavity located at a fixed water level with the lower port connected downwardly to the high-position sealed water tank. The water discharged from the lower port is displaced in the high-position sealed water tank by the air inhaled from the lower port, and water is added to the water receiving pan. When the water level in the water receiving pan rises to the specified water level that submerges the lower outlet and the lower port, the lower port can no longer inhale air, and the water surface of the water receiving pan is subject to atmospheric pressure, while the water in the high-position sealed water tank is not subject to atmospheric pressure due to the protection of the high-position sealed water tank. This ensures that after the lower port is submerged, the water no longer flows out, and the fixed water level is achieved. In addition, as time goes by, the water level will drop due to evaporation. Once the water level drops to expose the lower port, air will be replenished in the high-position sealed water tank, and the displaced water will raise the water level again, submerging the lower port to achieve pressure balance and keep the water surface stable, thereby achieving continuous odor isolation under unattended conditions. Therefore, the water used for complete odor isolation is limited to the water seal volume of the lower discharge port, which has the convenience of dry direct discharge, and has the advantages of extremely small water volume, water sealing and odor isolation, and is extremely water-saving and has no odor return.

In this way, before going to the toilet, in the waiting state, the counterweight body will buckle the water receiving tray upward to close the lower outlet through the lever action, and the fixed amount or fixed water level water injected by the water injection mechanism will also submerge the lower outlet, thereby playing the role of storing water and sealing the lower outlet to isolate odor; when going to the toilet, the feces and urine that fall into the dry direct discharge toilet fall to the water receiving tray, and under the impact force and gravity, the water receiving tray will tilt downward, so that the feces and urine will fall and be discharged; the water receiving tray for discharging feces and urine will naturally buckle upward to close the lower outlet again under the back pressure of the counterweight body due to the lighter weight, and the water injection mechanism will add water to the fixed amount of water that submerges the lower outlet or add water to the fixed water level that submerges the lower outlet. It should be noted that the fixed amount of water filling is achieved by a manual control valve for quantitative drainage or a quantitative drainage electric control valve that senses the human body leaving and is inductively linked. Fixed water level filling is a water injection pipe or water injection cavity located at a fixed water level with the lower port connected downwardly to the high-position sealed water tank. The water discharged from the lower port is displaced in the high-position sealed water tank by the air inhaled from the lower port, and water is added to the water receiving pan. When the water level in the water receiving pan rises to the specified water level that submerges the lower outlet and the lower port, the lower port can no longer inhale air, and the water surface of the water receiving pan is subject to atmospheric pressure, while the water in the high-position sealed water tank is not subject to atmospheric pressure due to the protection of the high-position sealed water tank. This ensures that after the lower port is submerged, the water no longer flows out, and the fixed water level is achieved. In addition, as time goes by, the water level will drop due to evaporation. Once the water level drops to expose the lower port, air will be replenished in the high-position sealed water tank, and the displaced water will raise the water level again, submerging the lower port to achieve pressure balance and keep the water surface stable, thereby achieving continuous odor isolation under unattended conditions.
