Embodiment Construction

[0057] The following describes the present invention in detail with reference to the drawings and specific embodiments.

[0058] Such as figure 1 with figure 2 As shown, the backpack fan system 100 includes: a backpack equipment 10, a fan device 20 and a connecting device 30.

[0059] Among them, the carrying equipment 10 can be used for the user to carry on the back. The fan device 20 can be used to generate air flow and guide air flow. The connecting device 30 is used to form the backpack 10 and the fan device 20 into a whole, and the connecting device 30 is connected to the backpack 10 and the fan device 20 respectively.

[0060] in particular, figure 2 As shown, the carrying equipment 10 may include: an equipment body 11 and a strap 12.

[0061] The equipment body 11 carries the battery pack 40, and the strap 12 is used to surround the user's body so that the user can carry the equipment body 11 on his back.

[0062] Such as Figure 2 to Figure 5 As shown, the fan device 20 may ...

Abstract

The invention discloses a blower device. The blower device comprises a housing, a fan and a motor, wherein an air duct is formed in the housing; the fan is arranged in the air duct; the motor is used for driving the fan to rotate around a pivot shaft; an operating handle is formed on or connected to the housing, and is used for operating the blower device; and the operating handle is arranged on the outer side of the air duct. The invention further discloses a backpack-type blower system. Besides the blower device, the backpack-type blower system also comprises backpack equipment, a connecting device, a battery pack and the like, wherein the backpack equipment is used for allowing a user to wear; the connecting device is used for transferring action force between the blower device and the backpack equipment; and the connecting device is connected to the backpack equipment and the blower device. Through the adoption of the scheme of the invention, the design of the operating handle improves the operation feeling, the backpack equipment can assist the user in mitigating the effect of the weight of the battery pack on operating a tool device, and the connecting device can transfer action force between the tool device and the backpack equipment, so that the operation burden of the user is alleviated, and the degree of comfort of the user during operation is improved.

Description

Technical field [0001] The invention relates to a backpack-type fan system and a fan device. Background technique [0002] As the power source of portable electric tools, battery packs have always been the main link that restricts the development of portable electric tools. In the past, the output voltage of battery packs is often low. When they drive high-power electric tools, they often cause insufficient power and poor endurance. . [0003] However, when the output voltage of the battery pack is increased by increasing the number of cells, the size and weight of the battery pack will increase accordingly, making it difficult to adapt the power tool or causing trouble to the user's operation. In particular, the increase in weight makes it difficult for the user to use flexibly. electrical tools. [0004] Fan is the collective name of two airflow devices, blower and blower. It is a common power tool that can be used to clean up or collect plant debris in gardening work. [0005] Ex...
