Description

Technical Field

[0001] The utility model belongs to the technical field of dust collecting bags, and in particular relates to a HEPA filter element type waterproof dust collecting bag. Background Art

[0002] The dust bag in the vacuum cleaner is installed inside the vacuum cleaner. After the airflow carrying dust enters the dust bag, the dust is intercepted by the dust bag. After the vacuum cleaner has been used for a period of time, the dust bag will be full of dust. In order to facilitate customer use and reduce secondary dust, the existing dust bag is set up once, that is, it is removed from the vacuum cleaner after being filled with dust, directly discarded, and a new dust bag is loaded into the vacuum cleaner. The bag body of the existing dust bag is generally made of non-woven fabric, which has good air permeability and can effectively intercept dust and other solid waste. However, non-woven fabric has poor waterproofness and loses its filtering function once it gets wet. Existing vacuum cleaners often bring water into the dust bag during the vacuuming process.

[0017] like Figure 1-2As shown, a HEPA filter cartridge waterproof dust bag comprises a plastic bag body 1 and a main body plastic part 2. The plastic bag body 1 is fixedly connected to the back of the main body plastic part 2. A dust suction channel 3 and a filter cartridge installation chamber 4 are arranged inside the main body plastic part 2. A front air outlet 5 connected to the filter cartridge installation chamber 4 is arranged on the front of the main body plastic part 2. A rear air outlet 6 connected to the filter cartridge installation chamber 4 is arranged on the back of the main body plastic part 2. A front dust suction port 7 connected to the dust suction channel 3 is arranged on the front of the main body plastic part 2. A rear dust suction port 8 connected to the dust suction channel 3 is arranged on the back of the main body plastic part 2. The rear dust suction port 8 and the rear air outlet 6 are connected to the inside of the plastic bag body 1 respectively. A filter cartridge 9 made of HEPA filter paper is installed in the filter cartridge installation chamber 4. The filter cartridge 9 is bonded to the main body plastic part 2 by hot melt adhesive. The airflow carrying dust and other garbage enters the plastic bag body 1 through the dust suction channel 3, and the solid matter or liquid matter is intercepted by the filter cartridge 9. The gas flows out from the front air outlet 5 after passing through the filter cartridge 9. Since the plastic bag body 1 is made of plastic, it can be used to hold liquids such as water. The filter element 9 made of HEPA filter paper will not lose its filtering function due to moisture.

[0018] Further, an activated carbon filter cotton 10 is installed in the filter element installation chamber 4, and the filter element 9 is located between the activated carbon filter cotton 10 and the rear dust suction port 8. The activated carbon filter cotton 10 can absorb the odor emitted from the plastic bag body 1 due to moisture and decay.

[0019] Furthermore, the filter element 9 is made of Hepa filter paper which is folded repeatedly into a pleated shape. The pleated Hepa filter paper increases the filtration area and improves the ventilation volume.

[0020] Furthermore, the plastic bag body 1 is fixedly connected to the back of the main plastic part 2 by hot melt adhesive. The plastic bag body 1 is sealed to the back of the main plastic part 2 to ensure the sealing of the inside of the plastic bag body 1.

[0021] Furthermore, a handle plate 11 is provided on the main plastic part 2, and both ends of the handle plate 11 are respectively fixedly connected to the main plastic part 2. The handle plate 11 facilitates the carrying of the dust bag.

[0022] Furthermore, the back sides of the main plastic part 2 are provided with guard plates 12 respectively, and the plastic bag body 1 is sandwiched between the guard plates 12. The guard plates 12 protect the connection between the main plastic part 2 and the plastic bag body 1.

[0023] Furthermore, the main plastic part 2, the guard plate 12 and the handle plate 11 are integrally formed of PP material (polypropylene).

[0024] Furthermore, the plastic bag body 1 is made of OPP material (polypropylene), CPE material (polyethylene), or PE material (polyethylene). The plastic bag body 1 has good waterproof performance and low cost.

[0025] It is worth mentioning that the technical features such as HEPA filter paper and activated carbon filter cotton involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected by conventional methods in the field, and should not be regarded as the invention point of this utility model patent. This utility model patent will not be further elaborated.

[0026] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field through logical analysis, reasoning or limited experiments based on the concept of the utility model on the basis of the existing technology should be within the scope of protection determined by the claims.
