[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figures 1-4 As shown, in this embodiment, a vacuum cleaner with anti-clogging suction port includes a vacuum cleaner body 1. The input end of the vacuum cleaner body 1 is connected to a flexible hose 2. A filter cartridge 3 is installed on the outside of one end of the flexible hose 2. A connecting pipe 4 is installed inside one end of the filter cartridge 3. One end of the connecting pipe 4 is connected to a suction head 5. A filter screen 8 is installed inside the bottom of the suction head 5. Both ends of the filter screen 8 are provided with first connecting holes 9. A first spring 10 is fixedly connected inside the first connecting hole 9. One end of the first spring 10 is fixedly connected with a first locking block 11. Both ends of the bottom of the suction head 5 are provided with second connecting holes 12. The first locking block 11 is locked inside the adjacent second connecting hole 12.

[0023] When the vacuum cleaner body 1 is working, the suction power is transmitted to the suction head 5 through the hose 2, filter cartridge 3 and connecting pipe 4. The suction head 5 performs vacuuming work. During this time, the filter screen 8 can intercept larger debris to prevent it from being sucked into the suction head 5 and avoid clogging of the suction head 5 or pipes.

[0024] When the filter screen 8 needs to be removed for cleaning, the first locking block 11 can be pressed to compress the first spring 10 and retract into the first connecting hole 9, thereby disengaging the first locking block 11 from the second connecting hole 12 and removing the filter screen 8 from the suction head 5.

[0025] Two connecting blocks 13 are fixedly connected to the outer side of the hose 2 and the connecting pipe 4 near the filter cylinder 3. A second spring 14 is fixedly connected inside the two connecting blocks 13. A second locking block 15 is fixedly connected to one end of the second spring 14. A third connecting hole 16 is opened on the surface of both ends of the filter cylinder 3. The second locking block 15 is locked into the interior of the adjacent third connecting hole 16.

[0026] The filter cartridge 3 is used to filter larger particles sucked in by the suction head 5 to prevent them from clogging the inside of the pipe. When the filter cartridge 3 needs to be removed, the second locking block 15 can be pressed in sequence to compress the second spring 14, causing the second locking block 15 to retract into the connecting block 13, that is, the second locking block 15 disengages from the third connecting hole 16, and the two ends of the filter cartridge 3 can be removed from the hose 2 and the connecting pipe 4.

[0027] Both ends of the filter cartridge 3 are equipped with sealing rings 17. The outer wall of one end of the hose 2 and the connecting pipe 4 is close to the inner wall of the sealing ring 17. The sealing ring 17 can ensure the airtightness of the connection between the hose 2, the connecting pipe 4 and the filter cartridge 3, and prevent dust from overflowing from the connection during the dust collection process.

[0028] The top of the filter cartridge 3 is fixedly connected to an external threaded tube 19. The outer thread of the external threaded tube 19 is connected to the filter element 18. After the hose 2 and the filter cartridge 3 are connected, the two ends of the external threaded tube 19 are connected to the hose 2 and the filter element 18 respectively. The external threaded tube 19 is used to install the filter element 18. After the filter cartridge 3 is removed from the hose 2 and the connecting tube 4, the filter element 18 can be replaced. The filter element 18 can filter larger particles in the dust, while smaller particles are sucked into the vacuum cleaner body 1.

[0029] An air pump 6 is fixedly connected to the top of the vacuum cleaner body 1. A thin tube 7 is fixedly connected to the output end of the air pump 6. The thin tube 7 is fixed to the outside of the flexible hose 2, and one end of the flexible hose 2 passes through the filter cartridge 3 and the external threaded tube 19 and is located at the top inside the filter element 18.

[0030] After each vacuuming session, the connecting tube 4 can be removed from the filter cartridge 3, and the air pump 6 can be started. The air pump 6 draws in air and outputs it to the filter element 18 through the thin tube 7 to perform back-blowing cleaning of the filter element 18. The dust filtered on the filter element 18 is blown off and blown out from the bottom of the filter cartridge 3, thus ensuring the service life of the filter element 18 and eliminating the need for frequent replacement of the filter element 18.

[0031] A fine filter cap is fixedly installed at one end of the thin tube 7 near the filter element 18. The fine filter cap is used to prevent smaller dust particles from entering the interior of the thin tube 7.

[0032] This utility model provides a vacuum cleaner with an anti-clogging suction port. The specific working principle is as follows: When the vacuum cleaner body 1 is working, the suction power is transmitted to the suction head 5 through the hose 2, filter cartridge 3 and connecting pipe 4. The suction head 5 performs vacuuming. During this time, the filter screen 8 can intercept larger debris to prevent it from being sucked into the suction head 5, thus avoiding blockage of the suction head 5 or the pipe. After vacuuming, the connecting pipe 4 can be removed from the filter cartridge 3, and then the air pump 6 can be started. The air pump 6 draws air and outputs it to the filter element 18 through the thin pipe 7 to perform back-blowing cleaning of the filter element 18. The dust filtered on the filter element 18 is blown off and blown out from the bottom of the filter cartridge 3, thereby ensuring the service life of the filter element 18 and eliminating the need to replace the filter element 18 frequently.

[0033] When the filter screen 8 needs to be removed for cleaning, the first locking block 11 can be pressed to compress the first spring 10 and retract into the first connecting hole 9, thereby disengaging the first locking block 11 from the second connecting hole 12 and removing the filter screen 8 from the suction head 5. When the filter element 18 needs to be replaced, the second locking block 15 can be pressed to compress the second spring 14 and retract into the connecting block 13, thereby disengaging the second locking block 15 from the third connecting hole 16 and removing both ends of the filter cylinder 3 from the hose 2 and connecting pipe 4. Then, the filter element 18 can be rotated to remove and replace it from the external threaded pipe 19.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
