These drawings are part of the disclosure of the present invention and 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 drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0026] Example 1

[0027] See Figure 1 As shown, this utility model discloses an installation structure for a suction and discharge device and an odorless toilet with the suction and discharge device. The toilet body 10 of the odorless toilet is one of a squat toilet, a seated toilet, or a urinal. The following description uses a squat toilet as an example.

[0028] See Figures 1 to 4 As shown, the suction and exhaust device includes a suction and exhaust connector 1, a suction and exhaust fan 2, an exhaust pipe 3, and a water inlet pipe 4. The suction and exhaust connector 1 includes an independent air intake chamber 101 and a flushing chamber 102. The air intake chamber 101 is connected to an air intake connector 11 and an exhaust connector 12. The air intake connector 11 is used to draw in the gas to be suctioned and exhausted from the toilet body 10. The exhaust connector 12 is connected to the exhaust pipe 3. The suction and exhaust fan 2 is installed in the exhaust pipe 3 to discharge the gas to be suctioned and exhausted drawn in by the air intake connector 12 to the sewage pipe 20. The flushing chamber 102 is connected to a water inlet connector 13 and a water outlet connector 14. The water inlet connector 13 is connected to the water inlet pipe 4. The water outlet connector 14 is used to flush water onto the toilet body 10.

[0029] The gas to be sucked and discharged refers to the gas in the sewage chamber inside the toilet body 10, which generally refers to the odor of excrement, but is not limited to this. When the suction and discharge device is working, most of the gas in the sewage chamber is sucked by the suction and discharge fan 2 and discharged into the sewage pipe 20, so that the toilet achieves the effect of being odorless.

[0030] In this embodiment, the suction and discharge device is located at the rear end of the toilet body 10. In other embodiments, the suction and discharge device may also be located at the front end of the toilet body.

[0031] This utility model separates the flushing pipe for toilet flushing and the suction and exhaust pipe for odor removal by setting independent air intake chamber 101 and flushing chamber 102 in the suction and exhaust connector, and connecting the water inlet pipe 4 and exhaust pipe 3 to the water inlet connector 13 and exhaust connector 12 respectively. This simplifies the structure of the water inlet pipe 4 and exhaust pipe 3, reduces manufacturing difficulty, and improves the reliability of the suction and exhaust device.

[0032] See Figures 2 to 4As shown, the air intake 11 and exhaust 12 are positioned opposite each other on opposite sides of the suction / exhaust connector 1. Two water outlets 14 are provided, positioned opposite each other on opposite sides of the suction / exhaust connector 1. The direction opposite the air intake 11 and exhaust 12 is defined as the front-back direction, the direction opposite the two water outlets 14 is defined as the left-right direction, and the direction perpendicular to the front-back and left-right directions is defined as the up-down direction. The water inlet 13 is positioned below the exhaust 12. The opposite arrangement of the air intake 11 and exhaust 12 reduces airflow resistance and increases the negative pressure suction force generated by the suction / exhaust fan 2 at the air intake 11, which helps improve the odor removal effect of the toilet body. The water inlet 13 is positioned below the exhaust 12, allowing the exhaust 12 to maintain a height close to that of the air intake 11, further reducing airflow resistance in the suction chamber 101. Since the water flow relies on positive pressure to rush towards the toilet body, even if the water inlet 13 is lower than the water outlet 14, the water flow can maintain a large potential energy to flush the toilet body 10.

[0033] Two water outlet connectors 14 are each connected to the toilet body 10 via a flushing pipe 5 for flushing the toilet body 10. The two flushing pipes 5 are connected to opposite sides of the toilet body 10. The suction and discharge connector 1 is installed at the rear end of the toilet body 10. The flushing pipes 5 extend from both sides of the toilet body 10 to the front end of the toilet body 10, so that water flows from both sides of the front end of the toilet body 10 to the toilet body 10.

[0034] The suction connector 11 is an arc-shaped elbow structure that curves downwards to form a downward-facing opening at its end. The downward-facing opening of the suction connector 11 prevents water from the toilet bowl 10 from entering the suction connector 11 due to the negative pressure of the suction fan 2, and also allows for the suction of air below it, resulting in a better suction effect. Furthermore, the arc-shaped elbow structure prevents dirt from accumulating on the outer surface of the suction connector 11 and facilitates cleaning.

[0035] See Figure 1 , Figure 2 and Figure 5As shown, to improve the stability of the suction and discharge device installation, a combination joint 6 is provided. The combination joint 6 includes a water pipe section 61, a first exhaust pipe section 62, a second exhaust pipe section 63, and a rigid connecting section 64. The connecting section 64 fixes the water pipe section 61, the first exhaust pipe section 62, and the second exhaust pipe section 63 relatively together. The connecting section 64 is connected to a sleeve section 65, which is used to insert a threaded connector 7 to fix the combination joint 6 in place. The combination joint 6 is installed inside the wall or on the wall surface. The combination joint 6 is preferably an integrally connected plastic or metal part. One end of the water pipe section 61 is connected to the water inlet connector 13 through a pipe, and the other end of the water pipe section 61 is used to connect to a water source, thus the water pipe section 61 forms part of the water inlet pipe 4. One end of the first exhaust pipe section 62 is connected to the exhaust connector 12 via a pipe, and the other end of the first exhaust pipe section 62 is connected to the air inlet of the suction and exhaust fan 2. One end of the second exhaust pipe section 63 is connected to the air outlet of the suction and exhaust fan 2, and the other end of the second exhaust pipe section 63 is used to connect to the sewage pipe 20, so that the first exhaust pipe section 62 and the second exhaust pipe section 63 form part of the exhaust pipe.

[0036] The sewage pipe 20 can be either the building's drain pipe 30 or the bend 40 connected to the toilet body 10. The toilet body 10 and the sewage pipe 40 form part of the toilet. In this embodiment, the sewage pipe 20 refers to the building's drain pipe 30, and the toilet's bend 40 is connected to the drain pipe 30 via a sealing ring. The toilet's bend 40 has a water seal to prevent the backflow of odors from the drain pipe 30 into the bathroom. This invention discharges odors from the toilet body 10 into the drain pipe 30, and the bend 40 prevents the backflow of odors discharged from the exhaust fan 2 into the drain pipe 30. Furthermore, to prevent odors from the drain pipe 30 from flowing back through the exhaust pipe 3, a one-way valve is installed inside the exhaust pipe 3.

[0037] The water pipe section 61, the first exhaust pipe section 62, and the second exhaust pipe section 63 are parallel circular pipes. The connecting section 64 consists of multiple connecting plates, each connecting plate connecting two adjacent circular pipes, with two connecting plates positioned between adjacent circular pipes. The sleeve section 65 is positioned between the two connecting plates of adjacent circular pipes. The sleeve section 65 has a cross-section of an elongated circular hole, extending along the distance between the two connecting plates to facilitate adjustment of the installation position of the combined joint 6. In this embodiment, the threaded connector 7 is a screw fixed to the ground, with two nuts on the screw, one at the top and one at the bottom of the sleeve section 65.

[0038] Example 2

[0039] See Figure 6As shown, the difference between this embodiment and Embodiment 1 lies in the installation method of the water pipe section 61, the first exhaust pipe section 62, and the second exhaust pipe section 63. In this embodiment, the water pipe section 61, the first exhaust pipe section 62, and the second exhaust pipe section 63 are inserted into a mounting connector 8 and installed on the wall. The mounting connector 8 is fixed to the ground by anchor bolts or fixed to the wall by mounting holes on the side and bolts. The water pipe section 61, the first exhaust pipe section 62, and the second exhaust pipe section 63 are each a round pipe. The water pipe section 61, the first exhaust pipe section 62, and the second exhaust pipe section 63 are respectively inserted into the through holes of the mounting connector 8, thereby realizing the installation and fixation of the water pipe section 61, the first exhaust pipe section 62, and the second exhaust pipe section 63.

[0040] In this embodiment, by inserting the water pipe section 61, the first exhaust pipe section 62, and the second exhaust pipe section 63 into the mounting connector 8, the structure of the mounting connector 8 can be simplified, making its manufacturing simpler and cheaper.

[0041] The remaining undescribed parts are the same as in Example 1, and will not be repeated here.

[0042] The above embodiment of the odorless toilet is illustrated using a squat toilet as an example. It is also feasible to replace the squat toilet with a urinal or a seated toilet. The urinal and seated toilet also have mounting holes for connecting the suction and discharge connector 1 to realize the connection between the suction and discharge device and the toilet body.

[0043] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that the remaining undescribed parts are prior art, and that all changes in form and detail made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims fall within the protection scope of the present invention.
