Description
Technical Field
The utility model relates to the technical field related to sanitary ware, in particular to a long-acting deodorizing floor drain with a negative pressure water supplementing function.
Background
The floor drain is used as an important component of a building drainage system, is widely applied to areas such as home balconies, kitchens, bath rooms, toilets and the like, and even the drainage of a wash basin and a bowl washing sink is required to be independently installed. According to statistics, the urban residences in China have about 4.9 hundred million sets, and each household at least needs to be provided with 4 to 6 floor drains, which means that the market of the floor drains is kept up to billions. However, the existing floor drain products have a plurality of defects in sealing performance, long-acting performance and maintenance convenience, and are difficult to meet the requirements of modern life on sanitation and health.
The common floor drain in the market is mainly divided into a water seal type floor drain and a unidirectional closed type floor drain. The water seal type floor drain forms a sealing barrier through water storage, but the water storage is easy to lose due to evaporation, and particularly in places such as kitchens, balconies and the like which are not usually supplemented with clear water, the water seal effect is invalid within 1 to 2 months due to the fact that the water seal type floor drain volatilizes about 1 to 2 millimeters of water depth every day. In addition, the actual water seal depth of many water seal type floor drains is lower than 50 mm specified by the standard, further exacerbating the lack of sealing performance. The unidirectional closed floor drain is closed by a hard plane or a soft rubber sealing port, but because the water flowing into the floor drain from the ground often contains impurities such as fiber strips, hair and the like, movable parts are easy to be blocked, and the problem of loose sealing is caused. Some novel floor drains such as electric control water supplementing type floor drains and pressing opening and closing type floor drains provide additional functions, but still have the problems of complex operation, loose closing or easy aging and deformation.
The waste gas components in the sewage pipeline mainly comprise hydrogen sulfide, ammonia gas, methane and other volatile organic compounds. Thus, the sealing performance of the floor drain is directly related to the indoor air quality and the health of the occupants. However, the existing floor drains are unsatisfactory in terms of long-term sealing and convenient maintenance, especially in areas where there is not always a clear water supplement on the floor, such as kitchens, balconies and toilet areas, and the problem is particularly pronounced.
In order to solve the problems, the utility model provides a negative pressure water supplementing long-acting deodorizing floor drain, which is characterized in that the water storage height of a negative pressure water storage device is set to be higher than the lower edge of a water outlet of a water storage cylinder, and the pipe orifice of a water outlet pipe of the water storage device is immersed below the water storage surface of the water storage cylinder by utilizing the siphon effect, bernoulli equation and the air pressure balance principle, so that the water flow is static and the long-acting retention of the water storage depth is realized. The design not only solves the problem of loss of the traditional floor drain water seal due to evaporation, but also remarkably improves the sealing performance and maintenance convenience of the floor drain, and provides an innovative solution for improving the indoor environment quality.

A sewage discharge connecting pipe is formed at the bottom of the floor drain cover main body 3, and a sewage sealing ring 302 is sleeved on the outer side of the building, and is used for being connected with a sewage pipeline pre-buried in the building. The negative pressure water receiver 4 is positioned at the middle upper part of the floor drain cover main body 3, the water level stored in the negative pressure water receiver is higher than the lower edge of the water cylinder water outlet 202 of Yu Cheng, and the pipe orifice of the water receiver water outlet pipe 403 extends to the lower part of the water storage surface of the water containing cylinder 203 so as to realize the functions of pressure balance and automatic water supplementing. The top of the negative pressure water receiver 4 is provided with a water receiver vent pipe 402, and the top port of the water receiver vent pipe 402 is covered with a vent pipe sealing cover 401 for venting when water is added.
The depth of the sealed filter cartridge 1 inserted into the water containing cylinder 203 is required to be more than 50 mm, so that the lower end of the sealed filter cartridge is ensured to be completely immersed in water, and the outside air is isolated from entering the floor drain. The filter screen 102 maintains a gap of at least 30 mm from the bottom of the water containing cylinder 203, so that sewage smoothly flows into the water containing cylinder 203. The length of the water containing barrel 203 needs to meet the national standard water storage depth requirement of 50 mm, and a certain height is additionally reserved for the design of water outlet turning. The water containing cylinder sealing ring 201 is positioned at the position 20 mm below the upper opening of the floor drain cover main body 3, so that a sufficient sealing space is reserved for the filter cylinder sealing ring 101. The height of the water outlet 202 of the water holding tube is optimally designed according to the drainage flow requirement, so that the water flow is smooth and the pressure balance is not damaged.
The bottom of the floor drain cover main body 3 is provided with a drain connecting pipe, and the diameter of the drain connecting pipe is designed to be matched with a 50 mm pipeline reserved for drain of the existing floor drain. The drain sealing ring 302 is sleeved outside the drain connecting pipe and is used for forming sealing connection with a drain pipeline pre-buried in the building.

The negative pressure water storage device 4 preferably adopts a PVC water inlet pipe with standard specification as a water storage container, and the volume of the water storage container can be flexibly adjusted according to actual requirements. The reservoir vent 402 is located at the top of the negative pressure reservoir 4 for venting when water is added. The vent pipe sealing cover 401 covers the end of the vent pipe 402 of the water receiver, so that the tightness in the water adding process is ensured. The water reservoir outlet pipe 403 is positioned at the bottom of the negative pressure water reservoir 4, and its pipe orifice extends below the water reservoir surface of the water reservoir 203 for realizing the automatic water replenishing function. The water outlet pipe 403 of the water storage device is designed with the opening facing downwards, so that the stored water is prevented from flowing backwards into the negative pressure water storage device 4.
The working principle of the negative pressure water supplementing long-acting deodorizing floor drain is that in the initial state, the water storage height in a negative pressure water receiver 4 is higher than the lower edge of a water storage barrel water outlet 202, and the pipe orifice of a water receiver water outlet pipe 403 is immersed below the water storage barrel 203. At this time, the negative pressure generated in the negative pressure water reservoir 4 and the external atmospheric pressure reach an equilibrium state on the pressure at both ends of the water outlet 202 of the water holding tube, so that the water flow is kept still, and the water holding tube 203 maintains a fixed water storage depth for a long time. Over time, the water in the water containing tube 203 is reduced due to volatilization, and when the water storage surface is lower than the pipe orifice of the water outlet pipe 403 of the water storage device, the pressure at the two ends of the water outlet 202 of the water containing tube is out of balance, and the water in the negative pressure water storage device 4 automatically flows out to supplement water. After the water replenishing flows to the water storage surface and the pipe orifice of the water outlet pipe 403 of the water storage device is sealed again, the pressure is restored to be balanced, and the water replenishing is stopped. The process realizes the automatic water supplementing function by utilizing the siphon effect, the Bernoulli equation and the air pressure balance principle, and remarkably prolongs the odor isolation effect of the floor drain.
The floor drain is convenient to clean and maintain. When the garbage in the sealed filter cartridge 1 needs to be cleaned, the sealed filter cartridge 1 is directly pulled out, and the garbage is dumped and then reinstalled. If the garbage in the water containing cylinder 203 needs to be cleaned, the garbage can be scooped by using a small spoon, and the water containing and sewage cleaning cylinder main body 2 does not need to be disassembled. If the water containing cylinder 203 needs to be thoroughly cleaned, the water outlet pipe 403 of the water storage device is detached and the water outlet of the negative pressure water storage device 4 is plugged, and then the water containing cylinder 203 is detached for cleaning.
The water replenishing operation of the negative pressure water reservoir 4 comprises the following steps of S1, pulling out the sealed filter cartridge 1, S2, sleeving a water pipe with a funnel on a water outlet pipe 403 of the water reservoir, S3, removing the exhaust pipe sealing cover 401, S4, adding water into the funnel until the water outlet pipe 402 of the water reservoir overflows, and S5, reinstalling the exhaust pipe sealing cover 401 on the exhaust pipe 402 of the water reservoir to complete the water replenishing operation.
The negative pressure water storage device 4 has various structural forms, and can be installed in an open or hidden mode according to actual requirements. If a concealed installation mode is selected, the negative pressure water reservoir 4 can be buried under the floor tile and arranged by utilizing the space of the sinking tank. If an open mounting mode is selected, the negative pressure water reservoir 4 can be mounted on a wall or a hand basin cabinet or the like. No matter what installation mode is adopted, the water storage height in the negative pressure water receiver 4 is required to be ensured to be higher than the lower edge of the water outlet 202 of the water containing barrel. In addition, the negative pressure water receiver 4 can be communicated with a plurality of floor drain housing main bodies 3 through pipelines, and is suitable for occasions requiring densely-installed floor drains, such as hotels, office places, apartment houses and the like. The concrete implementation mode is that a plurality of water outlet interfaces are additionally arranged at the bottom or the side surface of the negative pressure water receiver 4 and are respectively connected to water cylinder water outlets 202 of different floor drain housing main bodies 3 through pipelines, so that the multi-point water supplementing function is realized.
The floor drain disclosed by the utility model is wide in application range, and is especially suitable for the floor drain water supplementing requirement of a dry-wet separation area. For example, in a bathroom, a floor drain in a bathroom area can be a traditional water immersion floor drain, and a floor drain in a toilet area can be a negative pressure water supplementing long-acting deodorizing floor drain. The toilet area is usually lack of clear water supplement, the traditional water sealed floor drain is easy to lose the odor isolation function due to the volatilization of water, and the floor drain solves the problem through the automatic water supplementing function of the negative pressure water storage device 4. In addition, the floor drain can be adopted in areas with less water such as balconies and kitchens, and the water supplementing frequency is obviously reduced by reasonably adjusting the immersion depth of the water outlet pipe 403 of the water storage device, so that the service life of the floor drain is prolonged.
In summary, the negative pressure water supplementing long-acting deodorizing floor drain solves the problem that the traditional floor drain water seal is easy to fail by utilizing scientific principles and technical means through ingenious combination of the negative pressure water receiver 4 and the water containing cylinder 203, and simultaneously combines the maintenance convenience and the flexibility of appearance design. The long-acting sealing property, the one-machine multi-purpose property and the maintenance convenience of the floor drain lead the floor drain to have remarkable social value and market prospect.
