Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, and more specifically to a vacuum cleaner with a filter self-cleaning function. Background Art

[0002] A vacuum cleaner is a device that uses a gas pump to create a partial vacuum, generate suction and suck up dust from the floor or other locations. It was invented by Daniel Hess of the West Alliance Company in Iowa in 1860. The vacuum cleaner consists of a straw, wheels, and a dust bag. According to its structure, it can be divided into vertical, horizontal, and portable types; according to the way it is used, it can be divided into floor-standing, brush, and portable types. The principle is that the impeller is driven by an electric motor, and the negative pressure generated by the rotation of the impeller is used to suck the dust and debris from the outside together with the air into the box to achieve the cleaning purpose. Its purpose is to clean the dust, dirt, and debris that are generally difficult to remove on the floor, carpets, sofas, walls, furniture, clothes, and books on the bookshelf. Before using the vacuum cleaner, it should be installed according to the instructions and steps. After the power is turned on and the test run is carried out for 10 minutes, if the drive motor does not overheat, it can be used. Before each use, pay attention to whether the dust bag has been cleaned up, and the sharp objects and larger dirt on the site must be removed before use.

[0003] The shortcomings of the prior art: During the use of the existing vacuum cleaner, dust and dirt are easily attached to the surface of the filter, thereby affecting the purification efficiency of the filter. The filter needs to be cleaned and dredged manually, which is extremely inconvenient. For this reason, we propose a vacuum cleaner with a self-cleaning filter function. Utility Model Content

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model intercepts the dust through the action of the filter and makes it stay in the dust box, and then controls the operation of the driving motor, which drives the driving shaft to rotate, and the driving shaft drives the cam to rotate.

At this time, negative pressure gas is generated in the dust box 1 under the action of the negative pressure pipe 9, and then under the action of the dust collection pipe 11, the effect of sucking external dust into the dust box 1 is achieved.

[0023] Furthermore, a dust suction pipe 11 is fixedly connected to the front end of the dust suction box 1, and a dust suction head 12 is fixedly connected to the lower end of the dust suction pipe 11.
