Description
Technical Field
The invention relates to air pollution isolation equipment, in particular to an air pollution isolation device and an intelligent closestool.
Background
At present, with the rise of intelligent furniture, intelligent toilets are gradually popularized and step into common families. The intelligent closestool is a device for flushing sewage in the closestool by directly adopting tap water in a tap water pipe through an electromagnetic valve. The water inlet pipe and the flushing pipe are directly connected through the electromagnetic valve, and the flushing pipe is directly connected to the bottom of the water seal layer of the closestool. When the closestool is required to be flushed, the electromagnetic valve is opened, and tap water in the water pipe is directly communicated with the overshoot water pipe to flush the inside of the closestool. The intelligent closestool has the following defects: 1. after the intelligent closestool is washed, a water seal layer which is easy to grow bacteria is reserved at the bottom of the intelligent closestool. The water flushing pipe of the intelligent closestool is directly connected to the bottom of the water sealing layer of the closestool, so that bacteria in the water sealing layer of the intelligent closestool urinal can enter the tap water pipe along the water flushing pipe and the electromagnetic valve to pollute the tap water pipe, and the tap water pipe is harmful to the health of a human body. 2. When negative pressure is generated in the tap water pipe, the water seal layer in the flushing hose flows back into the tap water pipe, and further causes pollution to the tap water pipe. For example: when tap water is cut off, the first floor and the second floor share one tap water inlet pipeline, and when the tap water is opened in the first floor, negative pressure is generated in the tap water pipeline, so that the water sealing layer directly connected with the intelligent bathroom in the second floor is sucked back into the tap water pipeline.
In order to solve the problems, the invention patent number 2018102320498 discloses an air pollution isolation device and an intelligent closestool, wherein the air pollution isolation device comprises an upper pipe body and a lower pipe body, an elastic sealing assembly is arranged between the upper pipe body and the lower pipe body, a one-way air inlet assembly is arranged on the side part of the lower pipe body, a water flushing pipe is connected to the lower end of the lower pipe body, a water passing channel is formed by opening the elastic sealing assembly when the elastic sealing assembly is pressed, and the overflow area of the upper pipe body is larger than that of the water passing channel; when water enters the upper pipe body, the elastic sealing component is opened under the action of water pressure, when water flows through the water channel, the water speed is increased to drive the pressure in the lower pipe body to be reduced, and the unidirectional air inlet component automatically opens the sucked air; when the upper pipe body stops water inflow, the elastic sealing component is closed, water can still flow for a certain distance because of potential energy, negative pressure is formed in the lower pipe body, air is further filled into the lower pipe body and the flushing pipe, and after the water potential energy is released, a section of air dirt separation column is formed in the lower pipe body and the flushing pipe. The advantages are that: the intelligent closestool can prevent bacteria from infecting the tap water pipe through the water seal layer, and can prevent the water seal layer from flowing back into the tap water pipe, so that the intelligent closestool can be used healthily.
The technical scheme has the defects that: the intelligent closestool air dirt isolation device is characterized in that an elastic sealing component is added between an upper pipe body and a lower pipe body, and the flow rate of water is increased at a water outlet of the elastic sealing component to reduce the pressure of air in the lower pipe body, so that air is continuously fed from a unidirectional air inlet component; when water stops being supplied, the water in the lower pipe body and the water outlet hose continuously generates negative pressure due to flowing potential energy, so that air is continuously fed until the flowing potential energy is consumed, and air separation is generated. However, when the inlet water pressure of the pipe body is increased, the caliber of the lower pipe body is not increased synchronously, and the pressure in the water outlet pipe of the lower pipe body is increased. And the flow rate in the pipeline is determined by the pressure difference in the pipeline. The pressure difference between the pressure at the lower pipe body and the pressure at the water inlet of the air pollution-isolating device is continuously reduced along with the rising of the water inlet pressure, so the water flow rate at the breaking surface of the lower pipe body is also continuously reduced-! The water flow speed is reduced and the generated negative pressure is also reduced. When the water inlet pressure is increased to a specific point, the negative pressure generated by the water outlet of the elastic sealing assembly just can offset the force of the return spring of the unidirectional air inlet assembly. The rubber pad equal to the unidirectional air inlet component does not receive the thrust of air inlet and the thrust of the return spring, and water leakage is easy to occur. Therefore, the existing air pollution isolation device and intelligent closestool have harsh use conditions. Causes great inconvenience in practical use-!

Detailed Description
The invention is described in further detail below with reference to the embodiments of the drawings.
As shown in fig. 1-8, the air dirt separation device comprises a pipe body 1, wherein the upper end of the pipe body 1 is used for being connected with a water inlet valve (not shown in the drawing), the lower end of the pipe body 1 can be used for being connected with a water flushing pipe 2, a one-way air inlet assembly 3 is arranged in the pipe body 1, and the one-way air inlet assembly 3 comprises a pipeline assembly 4 and at least one-way ventilation device 5 arranged in the pipeline assembly 4; when water enters the pipe body 1, the unidirectional ventilation device 5 is closed by self reset force and impact force of the water; when the water in the pipe body 1 stops being supplied, the water can still flow for a certain distance because of potential energy, negative pressure is formed in the pipe body 1, air is filled into the pipe body 1, and after the water potential energy is released, a section of air dirt separation column 6 is formed in the pipe body 1. If the water flushing pipe 2 is connected to the lower end of the tank body, the water flushing pipe 2 and the tank body 1 together form an air dirt separation column 6.

The return force of the unidirectional aerator 5 is typically provided by a return spring.
The number of the one-way ventilation devices 5 is at least one, and the number of the one-way ventilation devices can be two, each one-way ventilation device 5 can be arranged at any position of the pipeline assembly 4 according to the requirement, and the sealing effect is better as the number of the one-way ventilation devices is larger. Because the function of synchronous air intake in the water intake process is omitted, in principle, only one-way ventilation device 5 is needed to achieve good sealing performance.
As shown in fig. 1, embodiment one: the one-way ventilation device 5 is one, the one-way ventilation device 5 is arranged at the end part of the transverse pipeline 7, and after water enters the transverse pipeline 7 along the longitudinal pipeline 8, the one-way ventilation device 5 is further pushed to be closed by water pressure on the basis of self restoring force. The dual force provides better sealing of the unidirectional breather 5. When water is fed, the water flows into the flushing pipe 2 along the pipe body 1; when water is stopped and enters water, water can still flow for a certain distance because of potential energy, negative pressure is formed in the pipe body 1, air is filled into the pipe body 1, and after the water potential energy is released, a section of air dirt separation column 6 is formed in the pipe body.
As shown in fig. 2, embodiment two: the one-way ventilation device 5 is one, the one-way ventilation device 5 is arranged at the upper part of the longitudinal pipeline 8, water in the pipeline 1 directly impacts the one-way ventilation device 5, and the one-way ventilation device 5 is further pushed by water pressure to be closed on the basis of self restoring force.
