Description

Technical Field

[0001] This application relates to the field of dust blowers, and in particular to a novel dust blower. Background Technology

[0002] A dust blower is a tool that uses a motor to drive the fan blades to generate blowing force to clean the area where dust needs to be blown away.

[0003] Currently, the dust blowers on the market generally include a main unit, a handle at the bottom of the main unit, a dust blowing component connected to the front of the main unit for blowing air, a speed adjustment component connected to the rear of the main unit for controlling the airflow of the dust blowing component, and a mainboard controller and power supply that are electrically connected to the dust blowing component and the speed adjustment component are located inside the handle.

[0004] Regarding the aforementioned technologies, the blowing angle of the dust blowing component is fixed relative to the handle. When the dust blower needs to blow dust from different angles at the same location, the blowing angle of the dust blowing component needs to be adjusted by changing the position and angle of the handle. This results in poor adjustability of the blowing angle of the dust blower, especially when encountering a blowing angle that is not easily achieved by changing the position or angle of the handle. Utility Model Content

[0016] Optionally, the dust blowing assembly comprises a friction pad, the friction pad is arranged between the control handle and the dust blowing shell, and the friction pad is coaxially fixed to the dust blowing shell and abuts against the control handle.

[0017] Optionally, the dust blowing assembly further comprises a dust blowing piece, the dust blowing piece is fixedly arranged in the air outlet and used for converging the air of the air outlet to blow away the dust more carefully.

[0018] Optionally, the dust blowing member comprises a plurality of dust blowing ports and a plurality of dust blowing brushes, the size or shape of the air outlet of each dust blowing port is different, and the number or thickness of the bristles of each dust blowing brush is different, so that the dust blower can replace the corresponding dust blowing member according to different dust blowing requirements.

[0019] Optionally, the control assembly further comprises a control panel, a power switch, a power module and a power display screen, the control panel is fixedly arranged on the control handle and electrically connected with the dust blowing module, the power switch is slidingly matched with the control handle and connected with the key of the control panel, the power switch is used for controlling the dust blowing module to be turned on or off, the power module is fixedly arranged on the control handle and electrically connected with the control panel, and the power display screen is fixedly arranged on the control handle and electrically connected with the control panel, and the power display screen is used for displaying the power of the power module.

[0022] In summary, the present application has at least one of the following beneficial technical effects:

[0023] When the air outlet angle of the dust blower needs to be changed and it is not easy to change the position or angle of the control handle, the dust blowing shell is rotated relative to the control handle, so that the angle of the air outlet relative to the control handle is changed, so that the position of the control handle is not moved or the angle of the control handle is changed to change the angle of the air outlet, so that the dust blower is more easily to meet different use requirements, and the blowing angle of the dust blowing assembly is fixed relative to the handle, when the dust blower needs to blow dust at different angles at the same position, the blowing angle of the dust blowing assembly needs to be adjusted by changing the position or angle of the handle, so that the blowing angle adjusting property of the dust blower is poor, especially when the blowing angle is not easy to change by changing the position or angle of the handle.

[0046] With reference to Figure 9 and Figure 10, the locking assembly 3 comprises a locking ring 31, a locking block 32 and a locking spring 33, the locking ring 31 is a hollow circular ring, the locking ring 31 is fixedly arranged in the dust blowing shell 11 and coaxially arranged with the rotating hole 114, when the dust blowing shell 11 rotates relative to the control handle 21, the position of the locking ring 31 is unchanged relative to the control handle 21, the locking block 32 is inclinedly and slidingly matched with the control handle 21 along the radial direction of the locking ring 31, the locking spring 33 is located between the locking block 32 and the control handle 21, one end of the locking spring 33 is fixedly connected with the locking block 32, and the other end of the locking spring 33 is fixedly connected with the control handle 21.

[0047] With reference to Figure 9 and Figure 10 , the locking ring 31 is provided with a plurality of locking grooves 311, each locking groove 311 is uniformly distributed around the axis of the locking ring 31, the groove body of the locking groove 311 is trapezoidal, the size of the groove body of the locking groove 311 near one end of the locking ring 31 is smaller than that of the groove body of the locking groove 311 away from the locking ring 31, the locking block 32 is fixedly provided with a locking protrusion 321 on the side close to the locking ring 31, the locking protrusion 321 is trapezoidal, the size of the locking protrusion 321 near one end of the locking block 32 is larger than that of the locking protrusion 321 away from the locking block 32, when the locking assembly 3 is locked, the locking protrusion 321 is inserted and clamped in any locking groove 311.

[0048] When the dust blowing shell 11 needs to rotate relative to the control handle 21, the user rotates the dust blowing shell 11 by exerting a certain force, when the dust blowing shell 11 is rotated by a certain force, the trapezoidal arrangement of the locking groove 311 and the locking protrusion 321 makes the locking ring 31 push the locking protrusion 321 to slide away from the locking groove 311, until the locking protrusion 321 is separated from the clamping of the locking groove 311, so that the locking assembly 3 is unlocked, so that the dust blowing shell 11 and the control handle 21 are relatively rotated, when the dust blowing shell 11 is rotated to the required position relative to the control handle 21, the locking protrusion 321 is inserted and clamped in the opposite locking groove 311 again, so that the locking assembly 3 is locked, so that the position between the control handle 21 and the dust blowing shell 11 is relatively fixed and not easy to rotate.

[0049] The implementation principle of the novel dust blower is as follows: when the air outlet angle of the dust blower needs to be changed and it is not easy to change the position or angle of the control handle 21 to achieve the change, the dust blowing shell 11 rotates relative to the control handle 21, so that the angle of the air outlet 112 relative to the control handle 21 changes, so that the angle of the air outlet 112 is changed without the position of the control handle 21 being moved or the angle of the control handle 21 being changed, so that the dust blower is more easily able to meet different use requirements, and the blowing angle of the dust blowing assembly 1 is improved to be fixed relative to the handle. When the dust blower needs to blow dust at different angles at the same position, the blowing angle of the dust blowing assembly 1 needs to be adjusted by changing the position or angle of the handle, so that the dust blower is not good at adjusting the blowing angle, especially when the blowing angle is not easy to change by changing the position or angle of the handle.

[0050] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
