[0022] The replacement mechanism 2 includes a mounting shell 201, a connecting line 202, a connector 203, a rotating disk 204, a first card slot 205, a fixed disk 206, a card block 207, a second card slot 208, a rubber pad 209, a protective shell 210, an interlocking groove 211, an interlocking frame 212, a filter frame 213 and a ventilation slot 214. The surface of one end of the monitoring machine 1 is threadedly connected to the mounting shell 201, one side of the surface of the mounting shell 201 is fixedly connected to the connecting line 202, one end of the connecting line 202 is fixedly connected to the connector 203, the outer surface of the connector 203 is fixedly connected to the rotating disk 204, and one side of the surface of the rotating disk 204 is provided with a first card slot 205, a fixed disk 206 is arranged on the outer side of the rotating disk 204, a block 207 is fixedly connected to one side of the surface of the fixed disk 206, a second slot 208 is provided on one side of the surface of the block 207, a rubber pad 209 is fixedly connected to the inner side surface of the second slot 208, a protective shell 210 is threadedly connected to one end surface of the connector 203, a fitting groove 211 is provided on one side surface of the protective shell 210, a fitting frame 212 is provided inside the protective shell 210, a filter frame 213 is provided inside the fitting frame 212, a ventilation groove 214 is provided on the outer side surface of the protective shell 210, and the protective shell 210 is provided with a ventilation groove 214. By installing the shell 201, the connecting wire 202, and the connector 2 03, the arrangement of the rotating disk 204, the first slot 205, the fixed disk 206, the block 207, the second slot 208, the rubber pad 209, the protective shell 210, the interlocking slot 211, the interlocking frame 212, the filter frame 213 and the ventilation slot 214. When the device needs to be installed, the fixed disk 206 is first threadedly connected to the position to be fixed, and then the protective shell 210 is inserted therein, and then the bottom surface of the rotating disk 204 is fitted with the fixed disk 206. Then, when the rotating disk 204 is rotated, the first slot 205 rotates into the block 207, and then the second slot 208 is engaged with the rotating disk 204, and the rubber pad 20 9, so that the rotating disk 204 and the card block 207 are more tightly engaged, so that the device can be fixed. After using it for a period of time, the device is removed and the filter needs to be replaced. First, the protective shell 210 is rotated to separate the protective shell 210 and the connector 203, and then the engaging frame 212 is taken out to make the engaging frame 212 disengage from the engaging groove 211. At this time, the filter frame 213 will also be taken out, and then the filter is replaced. The engaging frame 212 drives the filter frame 213 into the protective shell 210, and then the engaging frame 212 and the engaging groove 211 are engaged to fix them to complete the replacement of the filter.

[0023] Furthermore, the first card slot 205 and the card block 207 are in contact with each other, and five groups of the first card slot 205 are provided on the rotating disk 204. By setting the first card slot 205 and the card block 207, the first card slot 205 and the card block 207 can be better engaged with each other, so that the device can be better fixed and the device can be made more stable. By setting the first card slot 205 on the rotating disk 204, the friction can be greatly increased, so that the rotating disk 204 can be better fixed on the fixed disk 206.

[0024] Furthermore, five groups of blocks 207 are provided on the fixed disk 206, and five groups of engaging grooves 211 are opened on the protective shell 210. By setting the blocks 207 on the fixed disk 206, the friction between the fixed disk 206 and the rotating disk 204 can be increased, and the direction and degree of rotation of the rotating disk 204 can be limited. By setting the engaging grooves 211 on the protective shell 210, the engaging frame 212 can be better fixed and the filter screen will not slide.

[0025] Furthermore, the surface of the engaging frame 212 and the inner surface of the engaging groove 211 are fitted together, and the rotating disk 204, the block 207 and the second slot 208 constitute a locking structure. Through the arrangement of the engaging frame 212 and the engaging groove 211, the engagement of the engaging groove 211 is made more secure, and at the same time, the stability of the device is increased to collect oil smoke. Through the arrangement of the rotating disk 204, the block 207 and the second slot 208, the rotating disk 204 and the block 207 can be more closely fitted, so that the device will not fall off during use, and is convenient for disassembly.

[0026] Furthermore, the outer surface of the filter frame 213 and the inner surface of the protective shell 210 are in contact with each other. By setting the filter frame 213 and the protective shell 210, the filter can better filter the oil smoke and will not make the connector 203 too heavy to cause inaccurate detection.

[0027] Furthermore, the mounting mechanism 3 includes a fixing member 301, a fixing plate 302, a slide groove 303 and a limiting groove 304. The fixing member 301 is threadedly connected to the surface of one side of the monitoring machine 1, and the fixing plate 302 is arranged on the outer surface of the fixing member 301. The slide groove 303 is provided on the surface of one side of the fixing plate 302, and the limiting groove 304 is provided on the inner surface of the slide groove 303. Through the arrangement of the fixing member 301, the fixing plate 302, the slide groove 303 and the limiting groove 304, the fixing member 301 and the monitoring machine 1 are first threadedly connected, and then slid from top to bottom into the fixing plate 302, so that the fixing member 301 and the slide groove 303 are fitted and slid with the limiting groove 304. When completely sliding to the bottom, the limiting groove 304 limits the fixing member 301 to fix the device. When disassembly is required, the monitoring machine 1 can be lifted.

[0028] Furthermore, four groups of fixing members 301 are arranged on the monitoring machine 1, and the outer surface of the fixing member 301 fits with the surface of the limiting groove 304. By setting the fixing member 301 on the monitoring machine 1, the installation of the monitoring machine 1 is made more stable. By setting the fixing member 301 and the limiting groove 304, the fixing member 301 can be limited, so that the monitoring machine 1 will not slip and the device will not tilt.

[0029] Working principle: First, when the monitoring machine 1 needs to be installed, the fixing part 301 and the monitoring machine 1 are first threadedly connected, and then slid from top to bottom into the fixing plate 302, so that the fixing part 301 and the slide groove 303 are fitted and slid with the limit groove 304. When it slides completely to the bottom, the device is fixed. When the device has been working for a period of time and the filter needs to be replaced, the rotating disk 204 is first rotated. At this time, the first card slot 205 and the card block 207 will be disengaged, and the second card slot 208 and the rotating disk 204 will also be disengaged, so that the device is out of the engaged state, and then the connector 203 drives the protective shell 210 to be taken out, and then the protective shell 210 is rotated to twist it off, and then the chimeric frame 212 is pulled out upward to disengage it from the chimeric groove 211. At this time, the chimeric frame 212 will bring out the filter frame 213, and then the filter is replaced, and the chimeric frame 212 is installed in the protective shell 210, and then the device is installed by the same operation so that it can work normally.
