Problems solved by technology

However, there are still shortcomings in this solution. In actual use, users will find that some leaves are blocked before they touch the crushing mechanism, such as when the nozzle is blocked.
The shredding mechanism does not do a good job of completely shredding
And even if the leaves are crushed by the crushing mechanism, the crushed leaves are still easy to adhere to the crushing mechanism
In addition, the setting of the crushing mechanism will affect the working efficiency of the blowing device, so the actual effect is still unsatisfactory

Abstract

The invention relates to a blowing and sucking device, comprising: a housing; an air duct connected to the housing and having a nozzle connected to the outside world; a motor located in the housing and providing rotational power; a fan driven by the motor Rotating and generating airflow, wherein the fan is controllably rotating in a first direction and generating airflow moving from the nozzle to the inside of the housing; when the airflow entering the housing from the nozzle encounters blockage, The fan is controllably switchable from a first direction to rotate in a second direction and generates an air flow moving from the interior of the housing towards the nozzle.

Description

technical field [0001] The invention relates to a blowing and sucking device. Background technique [0002] Hair dryer is a kind of common cleaning tool, and its effect is to be used for clearing up the leaf scattered on the ground such as garden or street or rubbish. The principle of the hair dryer is that the fan rotates to generate airflow, which can quickly gather scattered leaves or garbage, thereby improving work efficiency. But because in some occasions, the leaves and rubbish gathered together still need to be cleaned up, the user needs to use additional tools, such as shovels, brooms, trash cans, etc., to clean up. This causes inconvenience to the user. [0003] A solution to this problem is to provide a blowing and suction device, which has an additional suction function in addition to the same blowing function as the hair dryer. The suction function of the blowing and suction device is to suck the leaves or garbage into the blowing and suction device, and disch...
