Detailed Description

The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

As shown in fig. 1 to 7, a dust collecting holder capable of improving a dust removing effect includes a housing 1 and a dust blowing chamber 7 provided in the housing 1. The front surface of the casing 1 is provided with a dust collecting cylinder insertion opening for installing the dust collecting cylinder 14 of the dust collector 200. In the vacuum cleaner 200, if the bottom of the handle 19 exceeds the bottom of the dust collecting container 14, the handle 19 is also received when the dust collecting container 14 is received in the dust collecting container insertion opening, and therefore, in this case, the size and shape of the dust collecting container insertion opening can be adjusted adaptively so as not to cause interference between the housing 1 and the handle 19 when mounted.

The front end opening of the dust blowing cabin 7 is provided with a sealing component 3, and the sealing component 3 is used for sealing the dust collecting barrel 14. The front end opening of the dust blowing cabin 7 is arranged corresponding to the dust collecting cylinder insertion opening, so that after the dust collecting cylinder 14 is arranged on the dust collecting cylinder insertion opening on the front surface of the machine shell 1, the dust collecting cylinder 14 is just aligned with the dust blowing cabin 7. A dust blower 6 for dividing the inner space of the dust blowing cabin 7 into a front space 7.2 and a rear space 7.3 is arranged in the dust blowing cabin 7, an inlet 7.4 of the dust blowing cabin 7 is communicated with the rear space 7.3, and an outlet 7.1 of the dust blowing cabin is communicated with the front space 7.2. The dust blower 6 is provided with a first dust blowing port 6.1 and a second dust blowing port 6.2, the first dust blowing port 6.1 is distributed with 8 along the circumferential direction, and the second dust blowing port 6.2 is distributed with 4 along the circumferential direction at the outer side of the first dust blowing port 6.1. The airflow from the first dust blowing opening 6.1 mainly acts on the dust in the central part of the dust collecting cylinder 14, and the airflow from the second dust blowing opening 6.2 mainly acts on the dust on the cylinder wall of the dust collecting cylinder 14. The two dust blowing openings can effectively remove dust in the dust collecting cylinder 14, and more efficient dust removal and cleaning are realized.

In order to further improve the dust removing capacity, the first dust blowing opening 6.1 is a circular opening, and the second dust blowing opening 6.2 is a long strip-shaped opening. The air-out width can be improved to rectangular shape opening to enlarge the active area, promote the cleaning power to section of thick bamboo wall dust.

In order to reduce the suction loss, an internal circulation air path is constructed inside the machine shell 1, as shown in fig. 5 and 6, an outlet 7.1 of the dust blowing cabin 7 is connected with an air channel 20, the other end of the air channel 20 is connected with an inlet of the dust bag containing cabin 10, an outlet of the dust bag containing cabin 10 is connected with an inlet of an exhaust fan 9, an outlet of the exhaust fan 9 is connected with an inlet of an air supply pipe 8, and an outlet of the air supply pipe 8 is connected with an inlet 7.4 of the dust blowing cabin 7. A dust bag 13 is provided in the dust bag storage chamber 10, and an inlet of the dust bag 13 is connected to an inlet of the dust bag storage chamber 10 or to an inlet of the air duct 20. A support screen 15 is provided at the outlet of the dust bag housing chamber 10. The support net plate 15 plays a role of supporting and blocking the dust bag 13, and prevents the dust bag 13 from being sucked into the exhaust fan 9. The dust collecting bag 13 is a non-woven cloth bag and has the functions of ventilation and filtration. With the above connection, in the dust collecting rack 100, starting from the dust collecting bag 13, the airflow circulation path sequentially includes: dust bag 13 → blower 9 → blower tube 8 → rear space 7.3 → dust blower 6 → front space 7.2 → air duct 7.1 → dust bag 13. The cleaned dust enters the dust collecting bag 13 along with the airflow, the dust is retained in the dust collecting bag 13 because the dust collecting bag 13 has a filtering function, and the airflow continues to circulate to bring the dust in the dust collecting cylinder 14 into the dust collecting bag 13 again.

In order to take out the dust bag 13 in the dust bag storage compartment 10 conveniently, the top of the machine case 1 and the top of the dust bag storage compartment 10 are both provided with openings, the dust bag storage compartment 10 is arranged in the machine case 1 and close to the opening of the machine case, the opening at the top of the machine case 1 is provided with a cover plate 2, and the top opening of the dust bag storage compartment 10 can be closed simultaneously after the cover plate 2 is closed. When the dust bag 13 is full of dust, the cover plate 2 needs to be opened, the dust bag 13 is taken out and the cover plate 2 is closed again after the new dust bag 13 is replaced.

In order to improve the stability of the dust collector 200 after installation, a supporting plate 1.1 is also arranged outside the front surface of the machine shell 1, and the supporting plate 1.1 is positioned below the dust collecting cylinder insertion opening. After the dust collecting cylinder 14 of the dust collector 200 is arranged in the front end opening of the dust blowing cabin 7, the supporting plate 1.1 plays a role of supporting the dust collecting cylinder 14.

The invention also provides a dust collector which comprises a dust collecting cylinder 14 and a handle seat 19, wherein an opening is formed in the bottom of the dust collecting cylinder 14, a cylinder cover is arranged at the opening in the bottom of the dust collecting cylinder 14, and the dust collector is matched with the dust collecting frame capable of improving the dust removing effect. The dust collecting cylinder 14 and the handle seat 19 can be inserted into a dust collecting cylinder insertion opening of the machine shell 1, and the dust collecting cylinder 14 can form sealing connection with the front end opening of the dust blowing cabin 7 through the sealing assembly 3 in a state that the cylinder cover is opened.

After the dust collecting cylinder 14 is mounted in place, the start button on the front of the dust collecting frame 14 is pressed, the exhaust fan 9 is operated, and the air passage in the dust collecting frame 100 generates circulating air flow. The dust in the dust collecting cylinder 14 leaves the dust collecting cylinder 14 under the action of the air flow and is carried by the air flow into the dust collecting bag 13. The dust is retained in the dust collection bag 13 under the obstruction of the dust collection bag 13, and the air flow continues to circulate for dust removal, finally realizing the cleaning of the dust collection cylinder 14. After the dust removal is completed, the vacuum cleaner 200 can be fixed to the dust collection frame 100 while maintaining its state.
