[0025] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0026] See also Figures 1 to 6 As shown, the utility model discloses an air-water separation joint, which is used to be installed on a toilet 100, and includes an air suction part 1 for connecting the toilet 100 and the air suction pipeline, and a water collecting part 2 for connecting the first flushing pipeline 200 and the second flushing pipeline. The water collecting part 2 is provided with a flushing connection port 21 for connecting the first flushing pipeline 200, and forms a waterway connection with the toilet 100 by means of the first flushing pipeline 200, so that the water flow from the second flushing pipeline passes through the water collecting part 2 and the first flushing pipeline 200 in sequence and flows to the toilet; the air suction part 1 and the water collecting part 2 can be selectively isolated to form an air-water separation structure.

[0027] The toilet 100 in this example is a squat toilet. In other embodiments, the toilet may also be a sitting toilet.

[0028] The direction of the joint toward the toilet 100 is defined as the front, and the opposite direction is the rear. The air suction part 1 is located in front of the water collecting part 2; the direction perpendicular to the front and back in the horizontal direction is defined as the left and right direction, and a flushing connection port 21 is provided on the left and / or right side of the water collecting part 2. In this example, the flushing connection port 21 is provided on both the left and right side walls of the water collecting part 2. In other embodiments, the flushing connection port 21 can also be provided only on the left or right side, so as to flush on one side of the squat toilet or on the front side of the squat toilet (in this case, the first flushing pipeline 200 is connected to the front side of the squat toilet, and a water flow from front to back is formed in the squat toilet).

[0029] The air intake part 1 and the water collecting part 2 are arranged along the front-to-back direction, and the flushing connection port 21 is arranged on the left and right sides, so that the water path bypasses the deodorizing air path and spreads to the left and right sides, thereby reducing the turning of the air path in the joint. Deodorization relies on the wind formed by the negative pressure fan connected to the air intake pipeline to suck the odor in the squat toilet, while flushing uses a water flow with a certain pressure to flush the inside of the toilet, so the pressure of the water flow is generally greater than the pressure of the odor. The utility model uses the air intake part 1 and the water collecting part 2 to be arranged along the front-to-back direction and the flushing connection port 21 to be arranged on the left and right sides, reducing the resistance that the odor flow needs to overcome, so as to better deodorize. In other embodiments, it is also feasible to arrange the air intake part 1 and the water collecting part 2 in the left-right direction or the up-down direction.

[0030] A partition wall 3 is provided between the air intake portion 1 and the water collecting portion 2, and an air intake connection port 11 for connecting an air intake pipeline is provided on the partition wall 3. The air intake portion 1 and the water collecting portion 2 are isolated by means of the sealed connection between the air intake pipeline and the air intake connection port 11 and the partition wall 3. The air intake portion 1 and the water collecting portion 2 can be isolated by directly plugging the air intake pipeline into the air intake connection port 11 and forming a sealed connection structure with the air intake connection port 11.

[0031] In other embodiments, an intake transition duct portion extending from the partition wall 2 to the rear side may be provided at the joint, and the rear end of the intake transition duct portion is used to connect the intake pipeline, thereby forming isolation between the intake portion 1 and the water collecting portion 2 by means of the intake transition duct portion and the partition wall 3.

[0032] The rear side wall of the water collecting part 2 is provided with an air-water connection port 22, and the air-water connection port 2 is used to connect the second flushing water pipeline and the air suction pipeline. This structure is suitable for the solution that the end of the air suction pipeline and the end of the second flushing water pipeline share a connector 300. If the end of the gas channel 301 of the connector 300 is flush with the end of the water channel 302, the matching joint structure is a structure with an air suction transition pipe; if the end of the gas channel 301 of the connector 300 extends further forward than the end of the water channel 302, then the matching joint structure is a structure without an air suction transition pipe as shown in this example.

[0033] The joint in this example connects the air intake pipe and the second flushing pipe through an air-water connection port 22. This has the advantage that the joint structure is simpler, and the two share a common interface, which can also reduce the size of the joint. In other embodiments, it is also feasible to set up independent air circuit connection ports and water circuit connection ports to connect the air intake pipe and the second flushing pipe respectively. In this case, there is no need for a connector 300 to connect the end of the air intake pipe and the end of the second flushing pipe. It is only necessary to connect the corresponding pipes respectively, which reduces the number of parts, has stronger versatility, and reduces installation requirements.

[0034] An air suction cavity 101 is formed in the air suction part 2, and the partition wall 3 forms the rear side wall of the air suction part 1. The front side wall of the air suction part 1 is provided with an air suction port 12, which is used to connect to the air inlet of the toilet 100, and the position of the air suction port 12 is higher than the position of the air suction connection port 11. Since the air suction pipeline is connected to the joint through the air-water connection port 22, and the diameter of the air-water connection port 22 is relatively large, the air-water connection port 22 is preferably set in the middle of the joint; the air suction pipeline is further connected to the air suction connection port 11 through a connector, and the air suction connection port 11 is also set in the middle of the joint; and since the air suction port of the toilet is set at a position close to the top, the position of the air suction port 12 needs to be set higher. Therefore, the position of the air suction port 12 is higher than the position of the air suction connection port 11, thereby forming a misalignment in the height direction, and the air suction cavity 101 is formed between the front side wall and the rear side wall of the air suction part 1, so that the structural design of the air suction part 1 is more reasonable. Depending on the size of the toilet, it is also feasible that the position of the air intake port is lower than the position of the air intake connection port 11.

[0035] In other embodiments, it is also feasible that the partition wall 3 directly forms the front side wall of the air intake portion 1. In this case, the air intake portion 1 is formed into a thin-walled structure, and there is no air intake cavity, which can improve the flow efficiency of odor in the air intake portion 1.

[0036] The flushing connection port 21 is arranged on a side wall of the water collecting portion 2, and a water collecting chamber 201 is formed in the area of ​​the water collecting portion 2 below the flushing connection port 21. The water collecting chamber 201 can stabilize the water flow. Since the air-water connection port 22 and the flushing connection port 21 are respectively located on different side walls of the water collecting portion 2, there is a certain degree of turbulence when the water flows through the water collecting portion 2. The existence of the water collecting chamber 201 ensures that the water flow must first fill the water collecting chamber 201 before flowing to the first flushing pipe 200 on the flushing connection port 21, which can stabilize the water flow and thus improve the flushing effect of the toilet.

[0037] The front side wall of the joint is against the side wall of the toilet 100, and the two form a surface contact, making the installation of the joint more stable. The lower surface of the joint is a slope, and the slope gradually slopes downward in the direction away from the toilet 100. The slope can reduce the volume of the water collection chamber 201, thereby reducing the amount of water collected in the water collection chamber, reducing the weight of the joint increased by water accumulation, and facilitating the stable installation of the joint. Secondly, the slope slopes downward from front to back to reserve enough space for the air-water connection port 22.

[0038] Figure 5 and Figure 6 The toilet 100, the first flushing pipeline 200 and the joint 300 are all prior art and are indicated by dotted lines.

[0039] The working process of the utility model is as follows: when flushing, water flows through the second flushing pipeline, the air-water connecting port 22, the water collecting chamber 201, the flushing connecting port 21, and the first flushing pipeline 200 to flow to the toilet to realize toilet flushing; when deodorizing, the odor in the toilet is discharged through the air inlet 12, the air inlet chamber 101, the air inlet connecting port 11, and the air inlet pipeline to achieve the purpose of deodorizing the toilet.

[0040] Although the present invention is specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that the remaining undescribed portions are prior art, and that various changes made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims shall fall within the scope of protection of the present invention.
