The gear ring 201 is meshed with the first gear 202, and the gear ring 201 is connected to the inside of the fixing frame 2 through the rotation of the first gear 202. When the hardened part 3 is damaged and needs to be replaced, the gear ring 201 is rotated to drive the first gear 202 to rotate. When the first gear 202 rotates, it will drive the second gear 203 at the bottom to rotate together. When the second gear 203 rotates, the rack 206 will slide on the side wall of the guide column 205, so that the clamping part 207 is disengaged from the clamping groove inside the hardened part 3. At this time, the hardened part 3 can be removed for replacement. During installation, the hardened part 3 is placed on the side wall of the leaf wheel 1, and the clamping part 207 is clamped into the clamping groove inside the hardened part 3 by rotating the gear ring 201 in the opposite direction. In this way, the hardened part 3 is installed and fixed, making the disassembly and installation of the hardened part 3 more convenient.

[0036] In some embodiments, see Figure 3 、 Figure 4 The card limit assembly includes a fixing member 2013, a first spring 2015 and a block 2014. The fixing member 2013 is fixedly mounted on the top of the page wheel 1. The fixing member 2013 is located inside the fixing frame 2.

The block 2014 is movably connected to the fixing member 2013 through the first spring 2015. The block 2014 matches the internal teeth of the gear ring 201. A lever 2 is fixedly mounted on the top of the gear ring 201. 011, a slide groove 2012 matching the shift lever 2011 is provided inside the fixing frame 2. By arranging the shift lever 2011 and the slide groove 2012, the gear ring 201 can be driven to rotate by shifting the shift lever 2011. By arranging the slide groove 2012, the rotation range of the gear ring 201 can be limited. By arranging the clamping block 2014 and the first spring 2015, the clamping block 2014 can be clamped between the internal teeth of the gear ring 201 to fix the gear ring 201 to a certain extent, thereby preventing the gear ring 201 from rotating due to external force when it does not need to rotate.

[0037] In some embodiments, see Figure 5 、 Figure 6 The evaporative heat dissipation component includes a fixed plate 401 and a movable plate 402. The fixed plate 401 is fixedly installed inside the leaf wheel 1. The movable plate 402 is slidably connected inside the fixed plate 401. One end of the movable plate 402 is fixedly installed on one side of the clip 207. By setting the fixed plate 401 and the movable plate 402, the clip 207 can be supported to a certain extent, making the movement of the clip 207 more stable.

[0038] In some embodiments, see Figure 5 、 Figure 6 , a first telescopic tube 403 and a second telescopic tube 407 are fixedly installed between the interior of the fixed plate 401 and one side of the movable plate 402, a first communicating groove 404 connected to the first telescopic tube 403 is provided inside the movable plate 402, a heat conduction cavity 405 connected to the first communicating groove 404 is provided inside the clamping piece 207, a ventilation cavity 410 matching the heat conduction cavity 405 is provided inside the clamping piece 207, a waterproof breathable membrane 406 is fixedly installed between the ventilation cavity 410 and the heat conduction cavity 405, a second communicating groove 408 connected to the ventilation cavity 410 is provided inside the movable plate 402, the second communicating groove 408 is connected to the second telescopic tube 407, an air pump 409 is installed in the second communicating groove 408, a liquid reservoir 4 is provided inside the leaf wheel 1, the first telescopic tube 403 and the second telescopic tube 407 are both connected to the liquid reservoir 4, the liquid reservoir 4 is filled with heat dissipation liquid, and the liquid reservoir 4 is filled with heat dissipation liquid. By providing the first telescopic tube 403 and the second telescopic tube 407, the first communicating groove 404 and the second communicating groove 408 can always be connected to the liquid storage tank 4 during the sliding of the movable plate 402. During the use of the impeller, the liquid in the liquid storage tank 4 will flow into the heat conduction cavity 405 through the first telescopic tube 403 and the first communicating groove 404 under the action of centrifugal force. Since the clamping member 207 is made of heat-conducting material, the heat generated by the hardening component 3 can flow into the heat conduction cavity 405. The interior of the hardening component 3 is cooled by evaporation of the liquid in the heat conduction cavity 405 and heat absorption. The evaporated gas is transported by the air pump 409 through the waterproof breathable membrane 406 into the ventilation cavity 410, and finally enters the liquid storage tank 4 through the second communicating groove 408 and the second telescopic tube 407. The evaporated gas can be well recycled, thereby reducing the loss of liquid in the liquid storage tank 4, which is more environmentally friendly.

[0039] In some embodiments, see Figure 7 、 Figure 8A filling port 411 is provided at the bottom of the leaf wheel 1, and a movable column 4111 is slidably connected between the filling port 411 and the liquid storage tank 4. A limit plate 4112 is fixedly installed on the side wall of the movable column 4111, and a second spring 4113 is fixedly installed between one side of the limit plate 4112 and the inside of the leaf wheel 1. A connecting hole 4114 connected to the liquid storage tank 4 is provided inside the filling port 411, and a sealing gasket 4115 matching the connecting hole 4114 is installed on one side of the movable column 4111. When liquid needs to be added to the liquid storage tank 4, the filling pipe is inserted into the filling port 411 to press the movable column 4111 into the liquid storage tank 4, so that the liquid in the filling pipe can enter the liquid storage tank 4 through the connecting hole 4114. By arranging the movable column 4111 and the sealing gasket 4115, leakage of liquid in the liquid storage tank 4 can be prevented during use.

[0040] The gear ring 201 , the air pump 409 and the sealing gasket 4115 involved in this embodiment can be freely configured according to the actual application scenario. The gear ring 201 , the air pump 409 and the sealing gasket 4115 work using methods commonly used in the prior art.

[0041] The working process and principle of the present invention are as follows: when the hardened part 3 is damaged and needs to be replaced, the gear ring 201 is driven to rotate by toggling the toggle lever 2011 so that the gear ring 201 drives the first gear 202 to rotate. When the first gear 202 rotates, it drives the second gear 203 at the bottom to rotate together. When the second gear 203 rotates, the rack 206 slides on the side wall of the guide column 205, so that the clamping part 207 is disengaged from the clamping groove inside the hardened part 3. At this time, the hardened part 3 can be removed for replacement. During installation, the hardened part 3 is placed on the side wall of the leaf wheel 1, and the gear ring 201 is rotated in the opposite direction so that the clamping part 207 is clamped into the clamping groove inside the hardened part 3, so as to install and fix the hardened part 3.
