Description

Technical Field

[0001] The utility model relates to the field of vacuum cleaners, in particular to a three-legged vacuum cleaner with stable movement and steering. Background Art

[0002] Vacuum cleaners can be divided into vertical, horizontal and portable types according to their structure. The working principle of a vacuum cleaner is to use an electric motor to drive the blades to rotate at high speed, creating negative air pressure in the sealed shell to absorb dust.

[0003] When a horizontal vacuum cleaner is used, the vacuum cleaner main unit is placed on the bottom surface and moves with the change of the suction area. During the movement of the existing vacuum cleaner main unit, the steering is not flexible, and the center of gravity is easily unstable and it may fall over. Utility Model Content

[0004] The purpose of the utility model is to provide a tripod type vacuum cleaner with stable movement and steering, so as to solve the problem that the main body of the existing horizontal vacuum cleaner is inflexible in steering and easy to tip over.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a tripod vacuum cleaner with stable movement and steering, comprising:

[0006] The vacuum cleaner main body is provided with symmetrically arranged running wheels on both sides, and the running wheels are rotatably mounted on the vacuum cleaner main body;

[0007] The direction wheel is rotatably mounted on a rotating seat, and the rotating seat is rotatably mounted on the bottom surface of the vacuum cleaner main body. The direction wheel and the two traveling wheels are arranged in a "triangle".

[0008] As a further description of the above technical solution:

[0009] A mounting groove is provided on the bottom surface of the vacuum cleaner main body, a connecting head is provided on the bottom surface of the mounting groove, and the rotating seat is rotatably installed on the connecting head.

[0010] As a further description of the above technical solution:

[0011] The rotating seat is hemispherical.

[0012] As a further description of the above technical solution:

[0013] The shell of the vacuum cleaner main body is provided with an arc-shaped rib arranged along the circumference of the running wheel.

[0014] As a further description of the above technical solution:

[0015] A plurality of parallel reinforcing plates are provided on the back of the arc-shaped retaining edge, and the reinforcing plates are fixedly mounted on the main body shell of the vacuum cleaner.

[0016] As a further description of the above technical solution:

[0017] The position of the rotating seat corresponds to the dust suction pipe joint of the vacuum cleaner host.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] 1. In the present invention, during the movement of the vacuum cleaner main unit, the running wheels and the steering wheels are arranged in a "triangle" shape to ensure that the vacuum cleaner main unit is stably supported and the movement is stable. At the same time, the steering wheel that can be rotated in front of the running wheels ensures stable steering, effectively solving the problem of inflexible steering and easy tipping of existing horizontal vacuum cleaner main units.

[0020] 2. In the present invention, when the vacuum cleaner is in use, the vacuum cleaner main unit is connected to the dust collection tube through the dust collection tube connector. When the vacuum cleaner main unit needs to be moved to meet the dust collection needs, the vacuum cleaner main unit is usually directly pulled through the dust collection tube. The position of the rotating seat corresponds to the dust collection tube connector, so that the rotating seat can flexibly adjust the direction as the dust collection tube is pulled, thereby making the movement and steering of the vacuum cleaner main unit stable and meeting the dust collection needs.

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1

[0029] See also Figure 1-3 The utility model provides a technical solution: a tripod vacuum cleaner with stable movement and steering, comprising:

[0030] The vacuum cleaner main unit 1 is provided with symmetrically arranged running wheels 11 on both sides, and the running wheels 11 are rotatably mounted on the vacuum cleaner main unit 1;

[0031] The direction wheel 2 is rotatably mounted on a rotating base 21 , and the rotating base 21 is rotatably mounted on the bottom surface of the vacuum cleaner main body 1 . The direction wheel 2 and the two traveling wheels 11 are arranged in a “triangle”.

[0032] The bottom surface of the vacuum cleaner main body 1 is provided with a mounting groove 12, and a connector 121 is provided on the bottom surface of the mounting groove 12. The rotating seat 21 is rotatably mounted on the connector 121. The rotating seat 21 is arranged in the mounting groove 12, and the mounting groove 12 is used to protect the rotating seat 21 and prevent hair from being entangled in the gap between the rotating seat 21 and the connector 121.

[0033] The rotating seat 21 is hemispherical to prevent collision damage during the rotation of the rotating seat 21 .

[0034] The housing of the vacuum cleaner main unit 1 is provided with an arcuate rib 13 arranged circumferentially along the running wheel 11. The arcuate rib 13 effectively protects the running wheel 11 and prevents hair from being entangled in the rotating shaft of the running wheel 11, thereby ensuring smooth movement.

[0035] A plurality of parallel reinforcing plates 131 are provided on the back of the arc-shaped rib 13 . The reinforcing plates 131 are fixedly mounted on the housing of the vacuum cleaner main unit 1 to prevent the arc-shaped rib 13 from deforming.

[0036] The position of the swivel base 21 corresponds to the suction hose connector 14 of the vacuum cleaner main unit 1. When the vacuum cleaner main unit 1 is in use, it is connected to the suction hose via the suction hose connector 14. When the vacuum cleaner main unit 1 needs to be moved to meet the vacuuming needs, the vacuum cleaner main unit 1 is usually pulled directly by the suction hose. The position of the swivel base 21 corresponds to the suction hose connector 14, allowing the swivel base 21 to flexibly adjust its direction as the suction hose is pulled, thereby ensuring stable movement and steering of the vacuum cleaner main unit 1 to meet the vacuuming needs.

[0037] Working principle: During the movement of the vacuum cleaner main unit 1, the running wheels 11 and the steering wheels 2 are arranged in a "triangle" to ensure that the vacuum cleaner main unit 1 is stably supported and the movement is stable. At the same time, the steering wheel 2 that can be rotated in front of the running wheel 11 ensures stable steering, effectively solving the problem of inflexible steering and easy tipping of existing horizontal vacuum cleaner main units.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
