Description

Technical Field

[0001] This utility model relates to the field of garden tool technology, and in particular to a garden hair dryer. Background Technology

[0002] In traditional garden blower designs, the duct and nozzle are usually integrated or fixedly connected, preventing users from flexibly adjusting the combination of the duct and nozzle according to actual needs.

[0041] Furthermore, the blower body 1 is provided with an air inlet and an air outlet. A protective cover is fixedly installed at the air inlet, and a plurality of ventilation grooves are provided on the protective cover. The air outlet is provided with a guide tube 11 for guiding the airflow, and a first limiting protrusion 12 is fixedly provided on the guide tube 11.

[0042] The blower body 1 has a motor 5 fixedly installed inside as a driving force.

[0043] The blower body 1 is fixedly provided with a handle 13, and the handle 13 is provided with a toggle switch for controlling the motor 5.

[0044] The blower is equipped with an impeller 6. The shaft of the impeller 6 is fixedly connected to the output end of the motor 5. The motor 5 provides driving force to the impeller 6 to drive the impeller 6 to rotate. A battery pack for providing energy is detachably installed at the bottom of the handle 13.

[0045] The guide tube 11 is fixedly provided with a wind cover 7, the main body of which is funnel-shaped. The wind cover 7 is gradually narrowed from the inside of the blower body 1 towards the guide tube 11, so as to guide the airflow to transition smoothly, reduce turbulence, make the outlet airflow more stable, and make the blown air more concentrated, reducing scattering.

[0046] Furthermore, the air duct 2 is used as a guide pipe 11 for the guide pipe 11, with a first protrusion 21 fixed at one end and a second limiting protrusion 22, which is the same as the first limiting protrusion 12, fixed at the other end.

[0047] The air duct 2 is fixedly provided with a number of first reinforcing ribs 23, which are evenly distributed in a circle to disperse the stress of the air duct 2 and make the structure of the air duct 2 more stable.

[0048] The first boss 21 has a first through groove for accommodating the disassembly component. A first positioning horizontal plate 24 and a first limiting plate 25 are fixedly installed in the first through groove. A first positioning post 26 is integrated on the first positioning horizontal plate 24.

[0049] The first through groove has a first connecting hole at both ends.

[0050] The first limiting protrusion 12 and the second limiting protrusion 22 have the same structure, both having a first inclined surface and a first vertical surface.

[0051] Furthermore, the nozzle 3 is used as the working nozzle of the guide tube 11, and it is provided with an air inlet and an air outlet. A second protrusion 31 is fixedly provided on the air inlet.

[0052] The nozzle 3 is provided with a number of second reinforcing ribs 32, which are evenly distributed around the circumference to disperse the stress of the nozzle 3 and make the nozzle 3 structure more stable.

[0053] The second protrusion 31 is provided with a second through groove for accommodating the disassembly component. A second positioning horizontal plate 33 is fixedly provided in the second through groove. A second positioning post 34 is integrated on the second positioning horizontal plate 33.

[0054] The second through groove has a second connecting hole at both ends.

[0055] The first reinforcing rib 23 and the second reinforcing rib 32 are provided to prevent deformation or cracking and extend the service life of key components.

[0056] The disassembly and assembly mechanism 4, located in the first through slot, serves the air duct 2 and the guide pipe 11, enabling the disassembly and assembly of the air duct 2 and the guide pipe 11. The disassembly and assembly mechanism 4, located in the second through slot, serves the air nozzle 3 and the air duct 2, enabling the disassembly and assembly of the air nozzle 3 and the air duct 2. It can also serve the air nozzle 3 and the guide pipe 11, enabling the disassembly and assembly of the air nozzle 3 and the guide pipe 11.

[0057] Furthermore, the disassembly and assembly mechanism 4 is provided in two sets, respectively used to cooperate with the first limiting protrusion 12 and the second limiting protrusion 22, including:

[0058] The main plate 41 has a groove at its bottom, and a locking block 42 is formed on the side wall of the groove. The main plate 41 is fixedly provided with a strip flange 43, which serves as a pressing part 44 for driving the main plate 41 to move. The strip flange 43 is provided to increase friction.

[0059] Spring 45 is located at the bottom of the main body plate 41 and is used to provide force to the main body plate 41;

[0060] One set of the disassembly and assembly mechanisms 4 uses locking blocks 42 to cooperate with the first limiting protrusion 12 to lock the air duct 2 and the guide pipe 11; the other set of the disassembly and assembly mechanisms 4 uses locking blocks 42 to cooperate with the second limiting protrusion 22 to lock the air nozzle 3 and the air duct 2.

[0061] A positioning plate 46 extends downward from the bottom of the main body plate 41. A through hole is provided on the positioning plate 46. A positioning rod 47 is rotatably installed inside the through hole. One set of positioning rods 47 is fixedly connected to the first connecting hole, and another set of positioning rods 47 is fixedly connected to the second connecting hole. The positioning plate 46 extends downward from the middle of the main body plate 41.

[0062] A positioning ring 48 is fixedly provided inside the groove, and the positioning ring 48 is located directly below the pressing part 44;

[0063] One end of the spring 45 is installed inside the positioning ring 48. One end of one spring 45 is fixedly connected to the first positioning plate 24 and sleeved on the first positioning post 26. One end of the other spring 45 is fixedly connected to the second positioning plate 33 and sleeved on the second positioning post 34.

[0064] The cross-section of the locking block 42 includes a second inclined surface and a second vertical surface. When the second vertical surface is in contact with the first vertical surface, it is in a locked state.

[0065] The main body plate 41 moves under the constraint of the positioning plate 46 and the positioning rod 47. When the pressing part 44 is pressed, the main body plate 41 moves around the positioning rod 47 as the center.

[0066] The first limiting plate 25 is used to limit the position of the main plate 41 so that the main plate 41 remains parallel when it is reset under the force of the spring 45.

[0067] A garden hair dryer, working principle as follows:

[0068] When disassembling duct 2 or nozzle 3:

[0069] Applying pressing pressure to the pressing part 44 drives the main body plate 41 to move under the limitation of the positioning rod 47, thereby causing the locking block 42 to move upward along the arc, thereby causing the locking block 42 to disengage from the first limiting protrusion 12 (or the second limiting protrusion 22) and achieve the unlocked state. At this time, the air duct 2 (or air nozzle 3) can be removed from the guide tube 11 (or air duct 2).

[0070] When installing duct 2 or air nozzle 3:

[0071] Hold the air duct 2 (or air nozzle 3) and move it toward the guide tube 11 (or air duct 2). During this process, the locking block 42 comes into contact with the first limiting protrusion 12 (or the second limiting protrusion 22), thereby causing the locking block 42 to be driven by force to move the main body plate 41 under the limitation of the positioning rod 47 and compress the spring 45. When the vertical surface of the locking block 42 moves to a 45-degree angle with the vertical surface of the first limiting protrusion 12 (or the second limiting protrusion 22), the locking block 42 is no longer under force. Under the action of the spring 45, the main body plate 41 is driven to reset, thereby driving the vertical surface of the locking block 42 to come into contact with the vertical surface of the first limiting protrusion 12 (or the second limiting protrusion 22), thereby achieving locking.

[0072] The above steps include the disassembly and assembly of duct 2 and guide tube 11, the disassembly and assembly of duct 2 and nozzle 3, and the disassembly and assembly of nozzle 3 and guide tube 11.
