Description

Technical Field

[0001] This application relates to the field of vacuum cleaners, and more particularly to an upright vacuum cleaner. Background Technology

[0002] Upright vacuum cleaners are widely used in people's daily lives. They generally consist of a main unit and a floor brush assembly connected to the lower end of the main unit. The main unit and the floor brush assembly are rotatably connected. To keep the main unit upright during use, a spring is provided at the end of the pivot between the floor brush assembly and the main unit. A protrusion is provided on the outside of the pivot. When the pivot rotates, the protrusion passes the spring and uprights the main unit. However, this limiting structure is not very stable. On the one hand, the spring relies on its own bending deformation to generate elastic force to hold the protrusion in place. After repeated bending deformation, the elasticity of the spring gradually decreases, causing slippage between the main unit and the floor brush assembly, making it inconvenient to use. On the other hand, this structure is complex, and the cost of installing the pivot, spring, and their connections is relatively high.

[0003] Chinese Patent Announcement No. CN201048904Y, authorized on April 23, 2008, discloses an upright vacuum cleaner. It includes a main unit assembly and a floor brush assembly head disposed at the bottom of the main unit assembly and rotatably connected to it. The vacuum cleaner has a first airflow channel, a second airflow channel, and an inlet channel. The inlet channel is connected to a dust collection bin, and the first airflow channel is connected to a suction port. The main unit assembly also includes a reversing valve for selectively connecting the inlet channel to either the first or second airflow channel. The reversing valve includes an inner valve and an outer valve, with the inner valve located inside the outer valve and the two valves being slidably disposed relative to each other. A first elastic element is disposed between the inner and outer valves to provide elastic restoring force to the inner valve. This reversing valve has a simple structure and is easy to install and maintain. Its shortcomings are that the limiting mechanism between the main unit and the floor brush assembly of this type of upright vacuum cleaner still uses a spring and a protrusion on the rotating shaft for limiting. The limiting structure is unstable, the structure is relatively complex, and the installation is inconvenient. Utility Model Content

[0004] To overcome the problems of complex limiting structure, troublesome installation, and poor stability between the main unit and the floor brush unit, this application provides an upright vacuum cleaner.

[0005] The upright vacuum cleaner provided in this application adopts the following technical solution:

[0006] include:

[0007] Floor brush components;

[0008] Host components;

[0009] A connecting mechanism for connecting the floor brush assembly and the main unit assembly;

[0010] The connecting mechanism includes a first connector rotatably mounted on the floor brush assembly and a second connector mounted on the first connector. One end of the second connector is snapped into the main unit assembly. The second connector has at least one protrusion. The floor brush assembly has a mounting block with a groove that mates with the protrusion. Rotating the main unit assembly causes the protrusion to engage or disengage from the groove, allowing the main unit assembly to rotate relative to the floor brush assembly or stand upright.

[0011] In one possible implementation, the protrusion has a first inclined portion at both ends, and the groove has an inclined surface that cooperates with the first inclined portion.

[0012] In one possible implementation, the mounting block is provided with a second inclined portion that cooperates with the first inclined portion.

[0013] In one possible implementation, the first connector is provided with a limiting block, and the floor brush assembly is provided with a limiting groove that cooperates with the limiting block.

[0014] In one possible implementation, both the first connector and the second connector are tubular structures.

[0015] In one possible implementation, the second connector is provided with a connecting ring, the connecting ring is provided with a plurality of first locking blocks, and the first connector is provided with a first locking groove that cooperates with the first locking blocks.

[0016] In one possible implementation, the first connector is provided with a second locking block, and the second connector is provided with a second locking groove that cooperates with the second locking block.

[0017] In one possible implementation, a connecting pipe is fixedly provided on the second connector, and the outer wall of the connecting pipe has threads. The air inlet pipe of the floor brush assembly passes through the first connector and is threadedly connected to the connecting pipe.

[0018] In one possible implementation, the first connector is provided with a sealing ring that mates with the air inlet pipe in the floor brush assembly.

[0019] In one possible implementation, the first connector has rotating rings at both ends, and the floor brush assembly has rotating grooves that cooperate with the rotating rings; the sealing ring has third locking blocks at both ends, and the rotating ring has third locking grooves that cooperate with the third locking rings.

[0020] In summary, this application offers the following beneficial technical advantages: by rotating the main unit, the protrusion engages or disengages from the groove, allowing the main unit to rotate or stand upright relative to the floor brush assembly. This effectively secures the main unit upright on the floor brush assembly without requiring cumbersome installation or operation, resulting in low cost and high stability.

[0033] Reference Figure 1-7 An upright vacuum cleaner includes a floor brush assembly 1, a main unit assembly 2, and a connecting mechanism 3. The main unit assembly 2 is rotatably mounted on the floor brush assembly 1, and the connecting mechanism 3 connects the floor brush assembly 1 and the main unit assembly 2. Specifically, the connecting mechanism 3 includes a first connector 4, a second connector 5, and a protrusion 6. The first connector 4 is rotatably mounted on the floor brush assembly 1, and one end of the second connector 5 is snapped into the main unit assembly 2, while the other end is snapped into the first connector 4. Rotating rings 7 are provided at both ends of the first connector 4, and rotating grooves 8 that cooperate with the rotating rings 7 are provided on the floor brush assembly 1. The first connector 4 and the second connector 5 are made of materials such as PP, ABS, PC, POM, and PA, thus possessing a certain surface hardness, high elasticity, and toughness. Both the first connector 4 and the second connector 5 are tubular structures, or both have ventilation chambers inside, facilitating the connection of airflow channels between the floor brush assembly 1 and the main unit assembly 2. The second connector 5 is symmetrically provided with protrusions 6, and the floor brush assembly 1 is symmetrically provided with mounting blocks 9. Each mounting block 9 has a groove 10 that mates with the two protrusions 6. By rotating the main unit assembly 2, the protrusions 6 are driven into or out of the grooves 10, allowing the main unit assembly 2 to rotate or stand upright relative to the floor brush assembly 1. This effectively fixes the main unit assembly 2 upright on the floor brush assembly 1 without complicated installation or operation, resulting in low cost and high stability.

[0035] The first connector 4 is provided with a limiting block 14, and the floor brush assembly 1 is provided with a limiting groove 15 that cooperates with the limiting block 14. This limits the main unit assembly 2, ensuring that the locking block can be accurately locked into the groove 10, and ensuring the stability of the main unit assembly 2 when it is upright.

[0036] The second connector 5 is provided with a connecting ring 16, and the connecting ring 16 is provided with a plurality of first locking blocks 17. The first connector 4 is provided with a first locking groove 18 that mates with the first locking blocks 17, and the first connector 4 is provided with a second locking block 19. The second connector 5 is provided with a second locking groove 20 that mates with the second locking block 19. This facilitates the installation and disassembly of the first connector 4 and the second connector 5, and improves the maintenance effect.

[0037] The second connector 5 is fixedly provided with a connecting pipe 21. The outer wall of the connecting pipe 21 has threads. The air inlet pipe 22 in the floor brush assembly 1 passes through the first connector 4 and is threadedly connected to the connecting pipe 21. The first connector 4 is provided with a sealing ring 23 that cooperates with the air inlet pipe 22 in the floor brush assembly 1. The two ends of the sealing ring 23 are provided with third locking blocks 24. The rotating ring 7 is provided with a third locking groove 25 that cooperates with the third locking ring.
