Problems solved by technology

[0002] As the power source of portable electric tools, battery packs have always been the main link restricting the development of portable electric tools. In the past, the output voltage of battery packs was often low. When they drive high-power electric tools, they often cause insufficient power and poor battery life.
[0003] However, by increasing the number of cells and increasing the output voltage of the battery pack, its size and weight will increase accordingly, making it difficult for the power tool to adapt to it or causing troubles to the user's operation, especially the increase in weight makes it difficult for the user to use flexibly electrical tools

Embodiment Construction

[0044] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0045] Such as figure 1 and figure 2 As shown, the backpack fan system 100 includes: backpack equipment 10 , fan device 20 and connection device 30 .

[0046] Wherein, the carrying equipment 10 can be used for the user to carry on the back. The blower device 20 can be used to generate and direct airflow. The connecting device 30 is used to integrate the backpacking equipment 10 and the fan device 20 as a whole, and the connecting device 30 is respectively connected to the backpacking device 10 and the fan device 20 .

[0047] in particular, figure 2 As shown, the carrying equipment 10 may include: an equipment body 11 and a strap 12 .

[0048] 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.

[0049] Such as Figu...

Abstract

The invention discloses a backpack type tool system which comprises a tool device, backpack equipment and a connecting device. The tool device is used for allowing a user to operate. The backpack equipment is carried on the back of the user. The connecting device can transmit counter-acting force suffered by the tool device during working to the backpack equipment. The tool device comprises a function part used for achieving tool functions, a motor used for driving the function part and a tool shell used for containing the motor. The backpack equipment comprises an equipment body used for being connected with or containing a power device, straps used for winding the body of the user and a connecting device connected to the tool device and the backpack equipment. The backpack type tool system has the beneficial effects that the backpack equipment can help the user to lower the influence of the weight of a battery pack on operation of the tool device, meanwhile, the connecting device can transit action force between the tool device and the backpack equipment, the operation burden on the user is lightened, and the comfort degree of user operation is improved.
