[0025] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0026] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0027] This embodiment mainly describes a garden hair dryer with adjustable length, as follows:

[0028] like Figures 1 to 6As shown, a garden hair dryer with adjustable length includes a fan body 1 and an air outlet duct 2 arranged at the end of the fan body 1 for discharging air. The air outlet duct 2 is fixedly connected to the fan body 1, and the air in the hair dryer body 1 is sent out through the air outlet duct 2. The air outlet duct 2 is provided with an air outlet tube 3, and the air outlet tube 3 is used to guide the wind. The air outlet tube 3 includes an outer air tube 31 and an inner air tube 32 slidably arranged in the outer air tube 31. The outer air tube 31 is sleeved at the blowing port, and a slide rail 311 is formed by the intersection of several limiting holes 3111 on the outer air tube 31. A limiting member 4 is rotatably connected to the inner air tube 32, and the limiting member 4 is used to limit the inner air tube 32. The limiting member 4 passes through the slide rail 311 and can slide along the slide rail 311 to drive the inner air tube 32 to slide relative to the outer air tube 31. The limiting member 4 has a limiting block 42. The shape of the required limit block 42 matches the limit hole 3111. After the limit member 4 is rotated, the limit block 42 cooperates with the limit hole 3111 to limit the inner air duct 32. When the limit member 4 is pushed to slide in the slide rail 311, the limit member 4 drives the inner air duct 32 to slide in the outer air duct 31 so that the outer air duct 31 is extended to the outside of the outer air duct 31 or retracted into the inner air duct 32. By pushing the limit block 42, the inner air duct 32 is pushed relative to the outer air duct 31. When the inner air duct 32 slides away from one end of the air outlet duct 2, the length of the air outlet duct 3 is extended. When the inner air duct 32 slides toward one end of the air outlet duct 2, the length of the air outlet duct 3 is shortened. When it is rotated to the length we need, rotate the limit member 4 to make the limit block 42 cooperate with the limit hole 3111 to fix the inner air duct 32 on the outer air duct 31. The air outlet duct 3 of the utility model can be freely adjusted in length according to the working environment and the height of the user, without causing the loss of parts of the air outlet duct 3. The adjustment process does not require disassembly or installation, which is simple and convenient.

[0029] like Figure 4 As shown, a threaded sleeve 321 is fixedly provided on the inner air duct 32, and the end of the limiting member 4 is provided with an external thread that cooperates with the threaded sleeve 321. The end of the limiting member 4 extends into the connecting tube and is threadedly connected to the connecting tube. The threaded sleeve 321 is threadedly connected to the limiting member 4, which not only plays the role of fixing the limiting member 4, but also limits the inner air duct 32 by rotating and adjusting the limiting block 42 and cooperating with the limiting hole 3111. The connection relationship between the limiting member 4 and the inner air duct 32 can also be that the end of the limiting member 4 extends into the inner air duct 32, and the limiting member 4 can rotate relative to the inner air duct 32. The end of the limiting member 4 is fixedly connected to a limiting plate, which is used to limit the limiting member 4 and prevent the end of the limiting member 4 from detaching from the inner air duct 32.

[0030] like Figure 1 、 Figure 2 and Figure 5As shown, the limiting hole 3111 is a runway-shaped hole, and the limiting block 42 is a runway-shaped limiting block 42. A strip-shaped sliding hole 3112 is provided between adjacent runway-shaped holes to connect the two limiting holes 3111 to form a track. The ends of the strip-shaped sliding hole 3112 are connected to the runway-shaped hole by a smoothly transitioning curved surface. The smoothly transitioning curved surface can reduce the friction between the limiting block 42 and the slide rail 311 and produce harsh noise. It also saves effort when adjusting the length of the air outlet 3 and is less likely to cause jamming. The distance between the two ends of the runway-shaped hole limiting block 42 is greater than the hole width of the strip-shaped sliding hole 3112 and less than or equal to the hole width of the limiting hole 3111. The distance between the two parallel lines of the runway-shaped limiting block 42 is less than or equal to the width of the strip-shaped hole.

[0031] Specifically, when the inner air tube 32 slides away from the end of the air outlet duct 2, the slide rail 311 on the outer air tube 31 may leak air, affecting the blowing effect of the hair dryer. To avoid air leakage, a wind shielding cover 5 is also provided on the outside of the outer air tube 31. The outer wall of the outer air tube 31 is symmetrically provided with a first slide groove 312 along the length direction of the outer air tube 31, and the inner wall of the wind shielding cover 5 is symmetrically provided with a first slide block 51 that extends into the first slide groove 312 and can slide along the first slide groove 312. When the length is adjusted, the wind shielding cover 5 can be slid to block the slide rail 311 of the air outlet duct 2. The cooperation of the first slide groove 312 and the second slide block 313 guides the wind shielding cover 5 to avoid the wind shielding cover 5 from getting stuck due to uneven force during the sliding process.

[0032] like Figure 5 As shown, a second sliding groove 322 extending along the length direction of the inner air duct 32 is symmetrically provided on the outer wall of the inner air duct 32, and a second sliding block 313 extending into the second sliding groove 322 and sliding along the second sliding groove 322 is symmetrically provided on the inner wall of the outer air duct 31. The first sliding groove 312 and the second sliding block 313 are used in conjunction with each other to guide the inner air duct 32, thereby preventing the inner air duct 32 from getting stuck due to uneven force during the sliding process.

[0033] Specifically, the limit member 4 includes a connecting rod 41 and a rotating handle 43. The limit block 42 is fixed on the connecting rod 41, and the rotating handle 43 is fixed on the upper end of the limit rod. The setting of the rotating handle 43 makes the contact area between the hand and the rotating handle 43 larger than the contact area between the hand and the limit column 22 during use, so that the connecting rod 41 can be easily rotated, and the adjustment is simple and labor-saving.

[0034] like Figure 3 、 Figure 5 and Figure 6As shown, the air outlet duct 2 has an insertion section 21 inserted into the interior of the outer air duct 31, and the outer wall of the insertion section 21 is symmetrically provided with a limit column 22. The inner wall of the outer air duct 31 is symmetrically provided with a notch 314 extending in the length direction of the outer air duct 31 so that the limit column 22 can be inserted. The inner wall of the outer air duct 31 is provided with two fixing holes 315 respectively connected to the two notches 314 and arranged along the circumference of the outer air duct 31. The two fixing holes 315 are centrally symmetrical with the center of the outer air duct 31 as the center, and the two fixing holes 315 are provided with a limit The elastic clip 316 of the column 22 is clamped. When the insertion section 21 is inserted into the outer air duct 31, the two limit columns 22 are inserted into the two notches 314 on the inner wall of the outer air duct 31 respectively. When inserted to the bottom of the notch 314, the outer air duct 31 is rotated clockwise to slide the limit columns 22 into the two fixing holes 315 and be clamped by the elastic clip 316 in the fixing holes 315. The distance between the two fixing holes 315 is smaller than the distance between the two notches 314, which can prevent the insertion section 21 from slipping out of the limit hole 3111.
