Backpack type blower system and blower device

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...

AI Technical Summary

Problems solved by technology

[0007] 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
