In the technical solution provided therein, a siphon tube is provided to accelerate the rising and falling process of the liquid level in the mixing tank, thereby ensuring the effective opening and closing action of the driving mechanism on the sewage outlet.

[0003] However, in actual use, it still has the following defects and shortcomings:

[0004] 1) For the siphon to trigger, the water level in the mixing tank must be higher than the siphon, and there must be no bubbles in the siphon that disrupt the siphon. However, these conditions are difficult to meet in practice.

[0005] 2) The liquid level in the mixing tank needs to reach the siphon line to achieve siphoning, and the triggering water level required for siphoning is relatively high;

[0006] 3) The siphon tube has two corners, and there is a high possibility that pollutants will be retained in the tube.

[0007] Therefore, there is an urgent need to provide an effective technical solution to solve the defects and shortcomings in the above-mentioned prior art. Utility Model Content

[0032] [First embodiment]

[0033] like Figure 1-4 The figure shows a bell-shaped siphon rainwater and sewage diversion device provided by the first embodiment of the present invention. Figure 1 and Figure 3 As shown, it includes a box body 1, on which a mixing port 11, a rain outlet 12 and a sewage outlet 13 are respectively opened. Rainwater and sewage can enter the interior of the box body 1 through the mixing port 11. When the sewage outlet 13 is opened, sewage can be discharged through the sewage outlet 13. When the sewage outlet 13 is closed, rainwater can be discharged through the rain outlet 12.

[0034] like Figure 1 and Figure 3 As shown, the interior of the box body 1 is divided into a mixing water chamber 1A and a rainwater chamber 1B by a partition 14. A lever assembly (not shown) is provided inside the box body 1. The lever assembly can realize the corresponding opening and closing action of the sewage outlet 13 according to the liquid level height in the rainwater chamber 1B. As one of the preferred implementation methods, the lever assembly in this embodiment can use the driving mechanism disclosed in the patent application with announcement number CN220704714U.

[0035] The improvement of this embodiment compared with the prior art is that: Figure 2 As shown, a bell jar 2 is also fixed inside the box body 1, and a siphon tube 4 is fixed inside the bell jar 2. The first end of the siphon tube 4 is connected to the inside of the bell jar 2, and the second end of the siphon tube 4 is connected to the rainwater chamber 1B, and the first end is arranged higher than the second end. By arranging the first end of the siphon tube inside the bell jar, the vacuum degree required for the siphon is reduced, making the siphon easier to form.

[0036] As a preference, Figure 4 As shown, the bell jar 2 in this embodiment is configured as a cylinder with a closed top and an open bottom, which facilitates processing and molding while making it easier to form a siphon.

[0037] A sewage interception net 3 is fixed at the bottom of the bell jar 2. By arranging the sewage interception net at the bottom of the bell jar, large particles of pollutants can be intercepted to prevent them from entering the siphon pipe. When the siphon ends, it will directly trigger the discharge of sewage from the rainwater and sewage diversion device, so that the water in the bell jar will have a backwash effect on the sewage interception net.

[0038] like Figure 4As shown, the siphon tube 4 of this embodiment includes a vertical tube 41 and a horizontal tube 42 connected vertically. The top opening of the horizontal tube 42 is higher than the opening of the vertical tube 41 away from the end of the horizontal tube. By arranging the siphon tube as a vertically connected vertical tube and a horizontal tube, there is only one corner inside the siphon tube. At the same time, the flow direction of the siphon tube can facilitate the direct downward discharge of pollutants, reducing the probability of pollutants being retained in the pipeline and having higher pollution resistance. The vertical tube 41 extends into the interior of the bell jar 2, and the horizontal tube 42 passes through the partition 14 and extends into the interior of the rainwater chamber 1B.

[0039] In order to realize the connection between the sewage interception net 3 and one end of the siphon pipe 4, a through hole 31 for passing the siphon pipe 4 is opened in the middle of the sewage interception net 3, and the outer wall of the siphon pipe 4 is fixedly connected to the inner wall of the through hole 31. A through hole is opened inside the partition 14 for the horizontal pipe 42 to pass through, and the outer wall of the horizontal pipe 42 is fixedly connected to the inner wall of the through hole, thereby realizing the connection between the other end of the siphon pipe 4 and the partition.

[0040] In order to meet the needs under different actual conditions, the siphon tube diameter of the siphon tube 4 in this embodiment can be set accordingly according to the siphon requirements, the height position of the first end of the siphon tube 4 inside the bell cover 2 can be set accordingly according to the siphon requirements, and the internal size of the siphon tube 4 extending into the rainwater chamber 1B can be set accordingly according to the siphon requirements, thereby further improving the scope of application of this embodiment to meet the siphon requirements under different actual conditions.

[0041] The working process of this embodiment is:

[0042] After the rainfall ends, the sewage outlet 13 is closed, and the water level inside the box body 1 continues to drop until it drops to the water level of the partition 14 and is divided into the mixing water chamber 1A and the rainwater chamber 1B. At this time, the water level inside the mixing water chamber 1A is higher than the height of the nozzle of the first end of the siphon tube, thereby triggering the siphon effect. The water inside the mixing water chamber 1A is introduced into the rainwater chamber 1B through the siphon of the siphon tube and then discharged from the rainwater outlet 12. The water level inside the mixing water chamber 1A gradually drops until it reaches the hook water level (such as Figure 3 As shown in FIG1 ), as the water level in the mixing chamber 1A gradually decreases, the siphon flow rate in the siphon tube will gradually increase, and then the water level in the mixing chamber 1A will quickly drop to the sewage level (as shown in FIG1 ). Figure 3 As shown), at this time, the lever assembly inside the box body 1 is driven to open the drain outlet to discharge the remaining water in the mixing chamber 1A. When the water level in the mixing chamber 1A is lower than the bell jar 2, the siphon in the bell jar 2 is destroyed, causing the water in the bell jar 2 to fall rapidly downward through the sewage intercepting net 3 and flow into the drain outlet 13. At this time, the water inside the bell jar 2 can backwash the sewage intercepting net 3.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
