This invention generally relates to the technical field of electric trimming devices, and more particularly, to a handheld electric pet trimming device.
Along with the societal development, electric trimming tools, such as electric scissors, shaving knives and nail sharpeners have been extensively used in people's daily lives. For the conventional trimming tools, hair and debris must be manually collected. For example, when using a conventional shaving knife, the hair shaved off must be cleaned manually, and when using a conventional pet electric push-shaver for removing a pet's floating hair, the hair removed also have to be manually collected. To solve this problem, a trimming tools connecting to a vacuum cleaner started to appear on the market. They commonly comprise a tool body, a connecting hose and a vacuum cleaner. Its operating principle is: when the vacuum cleaner creates a negative pressure, the hair and debris removed by the tool are absorbed into the vacuum cleaner through a negative pressure channel such that the functions of removing hair while vacuuming are realized.
However, when using the aforesaid trimming tool, to achieve a comfortable trimming angle, a user needs to rotate it from time to time. When the trimming tool is continuously rotated, the connecting hose may easily be tangled, which in turn narrows the negative pressure channel. Presently, there is a need to cause the hair and debris smoothly enter the vacuum cleaner from the inlet of the negative pressure channel. Under such circumstances, a 360-degree connecting structure is needed. Moreover, the electric trimming tool is powered by the vacuum cleaner, resulting in complicated circuit structure and high manufacturing cost.
The purpose of the present invention is to provide a handheld electric pet trimming device. According to the present invention, a 360-degree free rotation of the adapter is being used, which effectively solves the technical problem relating to a narrowed negative pressure channel due to the winding of the hose caused by the continuous rotation.
