Problems solved by technology

Existing electric fans using battery packs often combine the battery pack directly to the fan body. In order to ensure that users can operate the electric fan flexibly and provide a better operating experience, the battery pack must not be too heavy, so the existing fans are often not suitable for long-term use. time work needs

Embodiment Construction

[0048] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0049] 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 .

[0050] 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 .

[0051] in particular, figure 2 As shown, the carrying equipment 10 may include: an equipment body 11 and a strap 12 .

[0052] 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.

[0053] Such as Figu...

Abstract

The invention discloses a backpack type blower system. The backpack type blower system comprises backpack equipment, a blower device and a connecting device, wherein the backpack equipment is carried on the back of a user; the blower device is used for generating and guiding airflow; the connecting device can transfer the acting force of airflow generated by the blower device on the blower device to the backpack equipment; the backpack equipment comprises an equipment body for connecting with or containing a power supply device and backstraps for surrounding the body of a user; the blower device comprises an airflow element capable of rotating around a pivoting axis, a motor for driving the airflow element and a blower drum for containing the airflow element; and the connecting device is connected to the backpack equipment and the blower device. The backpack type blower system has the beneficial effects that the backpack equipment can help the user to reduce the influence of the weight of a battery pack on operation of the blower device; meanwhile, the connecting device can transfer the acting force between the blower device and the backpack equipment; the operation burden of the user is reduced; and the comfort level of user operation is improved.

Description

technical field [0001] The invention relates to a knapsack fan system. Background technique [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. [0004] Fan is a general term for two kinds of airflow equipment, blower and blower. It is a common power tool that can be used to clean or collect plant debris in gardening work. [0005] Existing fans are divided...
