Description

Technical Field

[0001] The utility model relates to the technical field of gardening tools, in particular to a folding blower. Background Art

[0002] Nowadays, people's pursuit of the quality of life is getting higher and higher, so the level of urban landscaping has been increasing year by year. In daily gardening maintenance work, blowers or blast blowers that can quickly clean up garbage such as fallen leaves and sand and gravel are increasingly used by garden workers, greatly improving work efficiency.

[0003] Most blowers or blast blowers on the market are of an integral structure, with a relatively large overall volume, which is not conducive to movement and storage. Moreover, after the growth of plants and trees in the green garden, the space is relatively narrow, and the blowers or blast blowers cannot blow the garbage in these narrow spaces due to the fixed angle, greatly limiting the use scenarios of the blowers or blast blowers. Summary of the Utility Model

[0004] To solve the above problems, the utility model proposes a folding blower, which solves the problems of inconvenient storage and non-adjustable blowing angle of the traditional blower.

[0005] The technical solution adopted by the utility model is as follows: A folding blower includes a base and a blowing part. A connecting pipe is connected between the base and the blowing part. A battery pack is detachably connected to the base. The blowing part includes a housing, a driving motor and a driving fan. The driving motor and the driving fan are located inside the housing. The output end of the driving motor is in transmission connection with the driving fan. The connecting pipe includes a first wire pipe and a second wire pipe. The first wire pipe is connected to the housing, and the second wire pipe is connected to the base. A corrugated pipe is connected between the first wire pipe and the second wire pipe. One end of the first wire pipe close to the second wire pipe is provided with a first hollow pipe, and the first wire pipe is clamped inside the first hollow pipe. One end of the second wire pipe close to the first wire pipe is provided with a second hollow pipe, and the second wire pipe is clamped inside the second hollow pipe. The first hollow pipe and the second hollow pipe are clamped, and a positioning sleeve is threadedly connected to the first hollow pipe, and the positioning sleeve is clamped with the second hollow pipe.

[0006] Through the above technical solution, the power supply of the battery pack is started, causing the drive motor to start working. The driving force is transmitted to the drive fan through the output end of the drive motor, causing the drive fan to rotate. The user can aim the blowing part at the place to be cleaned and quickly clean it using the wind force. A corrugated pipe is connected between the first wire conduit and the second wire conduit of the present utility model. The corrugated pipe has good bending performance, and during the bending process, the pipe wall always has good support, providing good protection for the wires inside the pipe. Therefore, after the user fully unscrews the positioning sleeve, the corrugated pipe can be bent, so that the blowing part can be bent relative to the base, greatly reducing the overall volume of the present utility model. At the same time, the blowing angle can also be adjusted, facilitating the user to clean the garbage in some narrow corners, and making it more convenient to use.

[0007] Further, a limiting protrusion is provided at the end of the first hollow tube, and a limiting notch is correspondingly provided at the end of the second hollow tube. The limiting protrusion and the limiting notch are snap-connected.

[0008] Through the above technical solution, the snap connection between the limiting protrusion and the limiting notch makes the assembly of the first hollow tube and the second hollow tube more firm after completion, avoiding the relative rotation of the first hollow tube or the second hollow tube during the process of screwing the positioning sleeve, and making it more convenient for the user to assemble and disassemble the first hollow tube and the second hollow tube.

[0009] Further, the number of the limiting protrusions on the first hollow tube is two, and the two limiting protrusions are symmetrically arranged; the number of the limiting notches on the second hollow tube is two, and the two limiting notches are symmetrically arranged.

[0010] Through the above technical solution, the cooperation between the two symmetrically arranged limiting protrusions and limiting notches makes the overall force of the first hollow tube and the second hollow tube more uniform, and the overall structure more stable.

[0011] Further, the first hollow tube includes a first sleeve and a first connecting cylinder. The first sleeve and the first connecting cylinder are integrally formed. The diameter of the first connecting cylinder is larger than that of the first sleeve. The first connecting cylinder is threadedly connected to the positioning sleeve. The first sleeve is snap-connected to the first wire conduit. The limiting protrusion is provided at the end of the first connecting cylinder.

[0012] Through the above technical solution, the integrally formed first sleeve and first connecting cylinder make the overall structure of the first hollow tube very simple, facilitating mass production in factories; the threaded connection between the first connecting cylinder and the positioning sleeve and the snap connection between the first sleeve and the first wire conduit enable the user to very conveniently disassemble and assemble the first hollow tube with the first wire conduit and the positioning sleeve, making it more convenient to use.

[0013] Furthermore, the second hollow tube includes a second sleeve and a second connecting tube, the second sleeve and the second connecting tube are integrally formed, the diameter of the second connecting tube is larger than the diameter of the second sleeve, the second connecting tube and the positioning sleeve are clamped, the second sleeve and the second threading tube are clamped, and the limiting notch is arranged at the end of the second connecting tube.

[0014] Through the above technical solution, the integrally formed second sleeve and the second connecting tube make the overall structure of the second hollow tube very simple, which is convenient for mass production in the factory; the second connecting tube and the positioning sleeve are clamped together, and the second sleeve and the second threading tube are clamped together, so that the user can easily disassemble and assemble the second hollow tube, the second threading tube and the positioning sleeve, which is more convenient to use.

[0015] Furthermore, an air intake grille and a mounting tube are provided in the outer shell, the air intake grille is provided at one end of the outer shell close to the first threading tube, the mounting tube is provided in the middle of the outer shell, the driving motor is located in the mounting tube, and the driving fan is located between the air intake grille and the mounting tube.

[0016] Through the above technical solution, the driving fan is located between the air intake grille and the mounting tube, so that the output end of the driving motor and the driving fan are closer, which greatly reduces the loss of driving force during the transmission process. The setting of the air intake grille can effectively prevent debris such as fallen leaves from being sucked into the driving fan and causing damage to the driving fan, thereby greatly improving the service life of the driving fan.

[0017] Furthermore, a handle is provided on the base, a button is provided on the handle, a control unit is connected to the button, the control unit is electrically connected to the battery pack and the drive motor, and the control unit is located inside the base.

[0018] Through the above technical solution, after the user presses the button, the control unit starts the battery pack, the drive motor starts working, and the driving force is transmitted to the drive fan through the output end of the drive motor, so that the drive fan rotates, and the blown wind is then directed to clean up fallen leaves, sand and gravel and other garbage. The user only needs to press a button to use the utility model for cleaning operations, which is very convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
