This invention relates to a dust collecting device and relates particularly to a dust collector capable of assisting the user in loading and unloading a dust collecting barrel quickly and conveniently.
Generally, a dust collecting device is usually used to collect and filter dirt and harmful substances in a working site where dust or substances harmful to health may be generated. The dust collecting device functions to reduce dust and harmful substances in the environment and helps decrease the hazard to human health. Referring to
If the conventional dust collecting device has been used for a long time, the accumulation of dust would have been caused. This requires cleaning of the dust collecting barrel 905. Thus, a detachable dust collecting barrel lid 904 is generally added to the dust collecting barrel 905. Accordingly, a large number of fastening members 909 may be disposed on the periphery of the dust collecting barrel lid 904 and adapted to fasten the lid 904 to the dust collecting barrel 905 in an airtight manner in order to prevent dust within the dust collecting barrel 905 from overflowing during the operation of the dust collecting device. However, the detachment or installation of the fastening members 909 may take a lot of time to unload or load the dust collecting barrel 905. Particularly, if the dust collecting device abuts against the wall or is situated on the corner, it is difficult to operate the device and the inconvenience is caused. Therefore, the primary subject of this invention is to find a solution to the problem of inconvenient detachment and installation of the dust collecting barrel of the conventional dust collecting device.
An object of this invention is to provide a dust collector capable of assisting the user in loading and unloading the dust collecting barrel quickly and conveniently.
To achieve the object, a dust collector with convenient loading and unloading duct collecting barrel of this invention includes a frame, a wind box disposed on the frame, a motor disposed on the wind box, an air guide cylinder disposed at a bottom of the wind box and situated relative to the motor, a gas inlet disposed on a periphery of the air guide cylinder, a telescopic tube connected to a bottom of the air guide cylinder, a dust collecting barrel lid connected to the other end of the telescopic tube, and a dust collecting barrel disposed under the dust collecting barrel lid. It is characterized in that the dust collector of this invention includes elements described as follows.
A base plate is fixed on an outer periphery of the bottom of the air guide cylinder, and two pivot ears each are disposed at a rear side of the base plate.
An operation unit is disposed in front of the frame. An end of the operation unit is pivotally connected to the two pivot ears of the base plate, and the operation unit extends towards the other side of the base plate.
A plurality of linking members can be provided. One end of each linking member is pivotally connected to the operation unit, and the other end of each linking member is pivotally connected to the dust collecting barrel lid.
Accordingly, the linking members are driven by the operation unit to move the dust collecting barrel lid upwards and downwards. When a user wants to unload the dust collecting barrel, he only needs to lift the operation unit up. This upward movement allows the linking members to move the dust collecting barrel lid upwards, thereby separating the dust collecting barrel lid from the dust collecting barrel. Thus, the dust collecting barrel is easily detached. When the user wants to load the dust collecting barrel, he only needs to swing the operation unit down. This downward swinging action allows the linking members to move the dust collecting barrel lid downwards, thereby closing the dust collecting barrel with the dust collecting barrel lid. It is noted that the dust collecting barrel lid can be forcedly attached to the dust collecting barrel by the gravity of the operation unit, which assists the user in loading and unloading the dust collecting barrel quickly and conveniently and increases the working efficiency greatly.
