[0053] The quick-release assembly 4 also includes a cylindrical rod 46, which is fixedly installed in the first through hole and rotates with the second through hole. Example 2

[0054] like Figures 9 to 11 As shown, the garden hair dryer with a battery life display function includes a hair dryer body 1, a panel 2, a nozzle 3, and a quick-release assembly 4.

[0055] Furthermore, the hair dryer body 1 is provided with a handle 11 and an air outlet pipe 12;

[0056] A protrusion 1201 is fixedly provided on the air outlet pipe 12, and the protrusion 1201 is provided with an inclined surface.

[0057] It also includes an extension tube 5, which is located between the air outlet duct 12 and the nozzle 3. A first protrusion 51 is fixedly provided on the extension tube 5. Both ends of the extension tube 5 are detachably connected to the air outlet duct 12 and the nozzle 3 respectively through quick-release components 4. A first flange 52 is provided on the extension tube 5. A first connecting groove is provided on the first flange 52. A third through hole is provided in the first connecting groove.

[0059] In the quick-release assembly 4 used to connect the extension tube 5 and the nozzle 3, the locking block 43 is used to cooperate with the first protrusion 51. This setting can extend the nozzle 3 to match different working scenarios. Example 3

[0060] like Figure 12 As shown, the garden hair dryer with a battery life display function includes a hair dryer body 1, a panel 2, a nozzle 3, and a quick-release assembly 4.

[0061] Furthermore, at least two upright plates 6 are fixedly provided at the end of the nozzle 3 and are evenly distributed around the outer edge of the nozzle 3. The upright plates 6 are provided with connection holes.

[0062] It also includes a nozzle head 7, on which at least two protruding frames 71 are fixed for fitting onto the outer edge of the upright plate 6. The protruding frames 71 are evenly distributed around the nozzle head 7. A crossbar 72 is fixed inside the protruding frame 71. The crossbar 72 has a threaded hole. The crossbar 72 is detachably connected to the upright plate 6 by screws. This configuration can be matched to different working scenarios by replacing different nozzle heads 7 (such as air collector nozzles, air diffusers, and anti-flying nozzles).

[0063] The garden hair dryer with a battery life display works as follows:

[0064] 1) When the main power of the hair dryer body 1 is turned on, the circuit board 2501 is simultaneously powered on. At this time, the circuit boards 2501 can be switched on and off by triggering the push-down switch 2503. When the circuit board 2501 is turned on, the display light source 2502 on it emits light and shines on the light guide plate to display real-time data.

[0065] 2) When changing different nozzles 3, first apply downward pressure 27 to the pressing part 44 on the connecting block 41, so that the connecting block 41 is pried under the limitation of the cylindrical rod 46, generating an upward arc movement on the locking block 43, thereby releasing the locking engagement between the locking block 43 and the protrusion 1201 (i.e., the locking block 43 and the protrusion 1201 are no longer in contact), at which point the nozzle 3 can be pulled outward and removed.

[0066] Then, the nozzle 3 to be replaced is put on the air outlet pipe 12, and the nozzle 3 is pushed towards the handle 11, so that the locking block 43 on the connecting block 41 contacts the inclined part of the protrusion 1201, so that the locking block 43 is subjected to force and feedback to the connecting block 41, causing the connecting block 41 to move in a seesaw manner under the constraint of the cylindrical rod 46, and compressing the spring 42. When the locking block 43 moves to disengage from the protrusion 1201, the connecting block 41 is driven to reset under the action of the spring 42, and a locking engagement is formed between the locking block 43 and the protrusion 1201. At this time, the replacement of the nozzle 3 is completed.
