[0027] like Figures 1 to 9 As shown, an exhaust mechanism of a cleaning machine comprises:

[0028] Cleaning machine body 1;

[0029] The exhaust mechanism 2 is provided on the cleaning machine body 1 and is used to exhaust the air and steam generated by the cleaning machine body 1 during use, and includes:

[0030] The exhaust seat 21 has a cavity 2101 inside, and an air hole 2102 communicating with the cavity 2101 is formed on the outer wall of the exhaust seat 21;

[0031] The middle plate 22 is installed in the cavity 2101 of the exhaust seat 21, and is provided with a fan-shaped connecting groove communicating with the cavity 2101;

[0032] The fan-shaped valve plate 23 cooperates with the fan-shaped connecting groove on the middle plate 22 to close or connect the fan-shaped connecting groove 2201;

[0033] The knob 24 is rotatably arranged on the exhaust seat 21 for holding operation, and the knob 24 is provided with an anti-slip texture for easy operation;

[0034] A positioning nut 25 is disposed in the exhaust seat 21;

[0035] The transmission rod 26 is rotatably disposed in the positioning nut 25, the bottom of which is connected to the fan-shaped valve plate 23, and the top of which is disposed in the knob 24. The transmission rod 26 is provided with a through hole 2601;

[0036] The following two states are available:

[0037] In the exhaust state, the knob 24 is turned to displace the fan-shaped valve plate 23 and the fan-shaped connecting groove 2201 to form a through channel for exhaust;

[0038] In the sealing state, the knob 24 is turned to make the fan-shaped valve plate 23 correspond to the fan-shaped connecting groove 2201, thereby closing the channel and sealing.

[0039] Specifically, in the exhaust state, the air hole 2102, the cavity 2101, the connecting groove and the through hole 2601 form a connecting channel, and in the sealing state, the channel is in a closed state.

[0040] Furthermore, the exhaust seat 21 is provided with threads, which cooperate with the threaded holes provided on the cleaning machine body 1, and the threaded installation method is convenient for disassembly and installation;

[0041] The exhaust seat 21 is fixedly provided with a flange 2104 for defining the installation position. When the exhaust seat 21 is installed, when the flange 2104 is connected to the cleaning machine body 1, the exhaust seat 21 cannot be downward.

[0042] Furthermore, a plurality of key slots are provided in the knob 24;

[0043] A plurality of key blocks 2602 are fixedly provided on the top of the transmission rod 26 for matching with the key slots. The key blocks 2602 are inserted into the corresponding key slots so that the transmission rod 26 is driven by the knob 24 and moves synchronously with the knob 24 .

[0044] Furthermore, a socket hole is provided on the exhaust seat 21 , in which a U-shaped pin 2103 is installed for fixing the positioning nut 25 , and the two edges of the U-shaped pin 2103 are in contact with the two sides of the positioning nut 25 , so that the positioning nut 25 can no longer rotate in the exhaust seat 21 .

[0045] Furthermore, it also includes an O-ring 27, which is arranged on the exhaust seat 21 and abuts against the flange 2104, and is used for sealing the installation between the exhaust seat 21 and the cleaning machine body 1 to avoid leakage at the connection.

[0046] Furthermore, a baffle 2501 extends from one end of the positioning nut 25 .

[0047] Furthermore, a protrusion 2603 is fixedly provided at the bottom of the transmission rod 26. The protrusion 2603 is used in conjunction with the baffle 2501 to limit the rotation angle of the transmission rod 26 so that it can only rotate 90 degrees. The cooperation between the protrusion 2603 and the baffle 2501 not only limits the rotation angle of the transmission rod 26, but also can position the two states, thereby facilitating blind operation.

[0048] An exhaust mechanism of a cleaning machine, the working principle is as follows:

[0049] When exhausting, the operating knob 24 is rotated, and under the cooperation of the key groove on the knob 24 and the key block 2602 on the transmission rod 26, the transmission rod 26 moves synchronously with the knob 24, and the transmission rod 26 drives the fan-shaped valve plate 23 to move. In this rotation direction, when the protrusion 2603 on the transmission rod 26 abuts against the baffle 2501 on the positioning nut 25, the transmission rod 26 can no longer rotate. At this time, the position of the fan-shaped valve plate 23 and the fan-shaped connecting groove is misaligned, and the air hole 2102, the cavity 2101, the connecting groove and the through hole 2601 form a connecting channel, and the air and steam generated when the cleaning machine body 1 is used are discharged;

[0050] During transportation, the operating knob 24 is rotated (in the opposite direction to that during exhaust), driving the transmission rod 26 to rotate, driving the fan-shaped valve plate 23 to move. When the protrusion 2603 on the transmission rod 26 abuts against the baffle 2501 on the positioning nut 25, the transmission rod 26 can no longer rotate. At this time, the position of the fan-shaped valve plate 23 corresponds to the position of the fan-shaped connecting groove, and the fan-shaped connecting pipe groove is closed, so that a connecting channel cannot be formed among the air hole 2102, the cavity 2101, the connecting groove and the through hole 2601, and it is in a closed state.
