Embodiment 1
[0088] As shown in Figures 6 to 9 and Figures 24 to 31, the mode switching mechanism includes a rotary handle 121, a rotating shaft 120 installed below the rotary handle 121, a rotating tooth 123, a cam 127, a torsion spring 124 and a first spring 126 , the first spring 126, the rotating tooth 123, the cam 127, and the pressing plate 125 are sequentially set on the rotating shaft 120 from top to bottom; in the natural state, the rotating tooth 123 and the cam 127 do not contact, and the central through hole of the rotating tooth 123 The inner surface of the inner surface is provided with a limit structure adapted to the outer surface of the rotating shaft 120, and the bottom surface of the rotating tooth 123 and the top surface of the cam 127 are provided with a matching transmission structure, so that the rotating tooth 123 drives the cam 127 to rotate. The cam 127 includes a protruding part 130, the torsion spring 124 is installed on the cam 127, the bottom of the rotating sh...
Embodiment 2
[0097] As shown in Figures 10 to 13, the mode switching mechanism includes a handle and a shaft, the shaft is installed under the handle, the shaft includes a protruding part 130, and the protruding part 130 is located in the second transmission part Above 823, it also includes a third spring that makes the shaft move upwards. The end of the shaft is in contact with or separated from the first transmission part 813 to control the opening or closing of the supplementary air valve 416. The protruding part 130 The self-cleaning valve 417 is controlled to open or close by contacting or separating from the second transmission part 823 . The supplementary air valve 416 has a tendency to close the supplementary air passage 75, so that the self-cleaning valve 417 has a tendency to close the self-cleaning air passage 74. This tendency can be achieved by using elastic parts, or by adjusting the supplementary air valve 416, self-cleaning The structural center of gravity of the valve 417 ...
Embodiment 3
[0102] The difference between this embodiment and Embodiment 2 is that, as shown in FIG. 33 , the self-cleaning valve 417 also includes a third rotating shaft 822 arranged at one end of the second cover part 824 and a limiting part extended from the second transmission part 823 825. The second transmission part 823 and the second cover part 824 are pivotally connected to the third shaft 822 , and the second transmission part 823 and the limiting part 825 are disposed on two sides of the third shaft 822 . A fourth spring is installed on the third rotating shaft 822 so that the limiting portion 825 tends to abut against the second cover portion 824 . When the protruding part 130 abuts against the second transmission part 823 from top to bottom, the second transmission part 823 is rotated downward, and since the limit part 825 abuts against the second cover part 824 upwards, the entire self-cleaning valve 417 rotates around the second The rotating shaft 821 rotates counterclockw...
