Example 1
Referring to fig. 1, in a first aspect, the present embodiment provides an anti-reverse smoke device, including a U-shaped pipe 1, an air inlet end of the U-shaped pipe 1 is connected with a smoke exhaust pipe, an air exhaust end of the U-shaped pipe 1 is connected with an air exhaust manifold, a liquid inlet pipe 2 and a liquid outlet pipe 3 are connected to a bottom of the U-shaped pipe 1, and the U-shaped pipe 1 is used for storing sealing liquid to prevent reverse smoke from entering the U-shaped pipe 1 and the smoke exhaust pipe.
Specifically, when the range hood works, the range hood discharges kitchen oil smoke into an exhaust manifold of a corridor through the U-shaped pipeline 1; when the range hood does not work, liquid is injected into the U-shaped pipeline 1, and the range hood is prevented from being poured back by the oil smoke in the exhaust manifold in a liquid sealing mode.
The liquid supplementing of the U-shaped pipeline 1 can be realized by arranging the liquid inlet pipe 2 so as to form a seal. When the U-shaped pipeline 1 is filled with liquid to form a seal, the liquid level at the water inlet end of the U-shaped pipeline 1 is higher than the liquid level at the air outlet end due to the pressure influence of the air outlet manifold, so that a liquid level difference is formed.
The arrangement of the liquid discharge pipe 3 can realize the liquid discharge of the U-shaped pipeline 1 so as to ensure that the range hood works normally.
In this embodiment, one end of the liquid inlet pipe 2 is connected to a domestic tap water pipe, and one end of the liquid discharge valve 5 is connected to a sewer.

the third liquid level sensor 8 is arranged on the outer wall of the exhaust end of the U-shaped pipeline 1, and the third liquid level sensor 8 is used for monitoring the highest limit of the liquid level in the U-shaped pipeline 1.
Specifically, the first liquid level sensor 6 is used for monitoring the liquid inlet level in the U-shaped pipeline 1. On one hand, the liquid supplementing limiting effect is achieved, when the liquid in the U-shaped pipeline 1 reaches the height which can be monitored by the first liquid level sensor 6, the purpose of forming a liquid seal is met, and then water adding can be stopped; on the other hand, the arrangement of the first liquid level sensor 6 can also play a role in resisting the pressure of the reverse oil smoke, and specifically comprises the following steps: when the U-shaped pipeline 1 is filled with liquid to form a seal, the pressure at two sides of the U-shaped pipeline 1 is balanced, but once the number of households using the range hood in a residential building is increased, the reverse oil smoke pressure at the side of an exhaust main pipeline is increased, the liquid level at the exhaust end of the U-shaped pipeline 1 can be reduced under the influence of the pressure, and the sealing effect is influenced; therefore, when the liquid level is lower than the monitoring value of the first liquid level sensor 6, the liquid is replenished into the U-shaped pipeline 1, and at the moment, because of the influence of the pressure of the exhaust main pipeline, newly-increased liquid flows to the air inlet end of the U-shaped pipeline 1, the liquid level difference between the liquid level at the air inlet end and the liquid level at the air outlet end gradually increases, namely the water level difference gradually increases until the new balance is reached, and the pressure of the inverted oil smoke from the exhaust main pipeline is resisted.
The second liquid level sensor 7 is arranged at the bottom of the U-shaped pipeline 1 and is used for monitoring whether liquid exists in the U-shaped pipeline 1. When the U-shaped pipeline 1 discharges the liquid completely, the range hood can normally generate suction and can be used normally.
The third liquid level sensor 8 is arranged on the outer wall of the exhaust end of the U-shaped pipeline 1, so that the excessive liquid level is prevented from entering the range hood, and the range hood is prevented from being damaged. When the third level sensor 8 detects the liquid level, it indicates that the liquid in the U-shaped pipe 1 has reached the ceiling, which needs to be discharged to achieve the effect of lowering the liquid level. Further, when the liquid in the U-shaped pipeline 1 reaches the highest limit, an alarm is sent to a user through an alarm to remind the user to check the system.
In this embodiment, a communicating pipe 9 is disposed at the bottom of the U-shaped pipe 1, the U-shaped pipe 1 is connected to the liquid inlet pipe 2 and the liquid outlet pipe 3 through the communicating pipe 9, a liquid inlet valve 4 is disposed between the communicating pipe 9 and the liquid inlet pipe 2, a liquid outlet valve 5 is disposed between the communicating pipe 9 and the liquid outlet pipe 3, and the liquid inlet valve 4 and the liquid outlet valve 5 are all electric ball valves. Specifically, the communicating pipe 9 is used for communicating the liquid inlet pipe 2 and the liquid outlet pipe 3, and one communicating pipe 9 is connected with the U-shaped pipeline 1 and then connected with the liquid inlet pipe 2 and the liquid outlet pipe 3.
When being equipped with communicating pipe 9, second level sensor 7 locates communicating pipe 9 and is close to the tip of U type pipeline 1, should be U type pipeline 1 and communicating pipe 9 intercommunication, so only need install second level sensor 7 in communicating pipe 9's tip, whether still have the existence of liquid in the U type pipeline 1 that can be more accurate monitoring.
In particular, the air inlet end of the U-shaped duct 1 should be high enough to prevent liquid from entering the range hood on the one hand and to resist the reverse pressure of the cooking fumes from the fume exhaust manifold on the other hand.

When the range hood works, namely the U-shaped pipeline 1 does not need to be filled with liquid:
the control module receives a monitoring signal of the second liquid level sensor 7, if the second liquid level sensor 7 monitors that the liquid level exists, a liquid draining instruction is sent to the control module, the control module controls the liquid draining valve 5 to be opened, and liquid in the U-shaped pipeline 1 is drained; and the control module controls the liquid inlet valve 4 to be closed, so that liquid is prevented from flowing into the U-shaped pipeline 1 from the liquid inlet valve 4.
When the range hood is not in operation, then the U-shaped duct 1 needs to be filled with liquid to form a liquid seal:
the control module controls the liquid inlet valve 4 to be opened, sealing liquid is injected into the U-shaped pipeline 1, the first liquid level sensor 6 monitors the liquid level condition at the moment, when the liquid level is monitored, a signal is sent to the control module, the control module closes the liquid inlet valve 4, and the liquid injection flow is finished.
When the third liquid level sensor 8 monitors the liquid level at any time, a signal is sent to the control module, the control module opens the liquid discharge valve 5 to discharge the liquid in the U-shaped pipeline 1, and the liquid in the U-shaped pipeline 1 is prevented from entering the range hood to cause damage to the range hood.
In this embodiment, the anti-tilting oil smoke system further includes an anti-freezing module and an alarm module;
the anti-freezing module comprises an anti-freezing button, the anti-freezing button is connected with the control module, the anti-freezing button is used for inputting an anti-freezing instruction to the control module, and the control module executes the anti-freezing instruction to control liquid inlet and liquid discharge of the U-shaped pipeline 1;
specifically, the anti-freezing function can be used according to the requirement, when a user uses the anti-freezing capability, the anti-freezing button is pressed down, the control module receives an instruction for starting the anti-freezing button, and the anti-freezing action is circularly executed;

It is noted that the action of the liquid discharge valve 5 and the liquid inlet valve 4 has a certain time delay, and a certain time is reserved between the opening and the complete opening, and a certain time is reserved between the closing and the complete closing, so that when the liquid discharge valve 5 is in the process of opening, complete opening, closing and complete closing and the liquid inlet valve 4 is in the process of opening, complete opening, closing and complete closing, a certain liquid level difference can be formed, and the effect of liquid flowing in the U-shaped pipeline 1 is achieved; thereby realizing the flow of liquid in the U-shaped pipeline 1 and achieving the anti-freezing effect.
