Description

TECHNICAL FIELD

[0001] The utility model belongs to cloth bag dust collector field, concretely relates to a novel cloth bag dust collector. BACKGROUND

[0002] The cloth bag dust collector refers to the dust collector with cloth bag as filter element, and its principle is to use airflow to carry dust from inside to outside through the cloth bag, so as to filter out the dust and collect it in the cloth bag. Since the cloth bag undertakes both filtering and dust collecting, the ventilation efficiency of the cloth bag will gradually decrease as the dust accumulates in the cloth bag. In actual use, the dust will not only accumulate at the bottom of the cloth bag, but also directly adhere to the periphery of the cloth bag, resulting in too fast and large decrease of the ventilation efficiency of the cloth bag. Adding a knocking mechanism in the cloth bag dust collector is a common method for maintaining the ventilation efficiency of the cloth bag. The principle of the knocking mechanism is to knock the cloth bag to make it shake during the dust removal process, so as to shake off the dust adhering to the side wall of the cloth bag and make the dust accumulate at the bottom of the cloth bag, so that the side of the cloth bag can be continuously ventilated. However, the knocking assembly provided in the existing cloth bag dust collector generally has the problems of single knocking point and low knocking frequency. To solve the above problems, the utility model provides a novel cloth bag dust collector. SUMMARY
