Description

Technical Field

[0001] The utility model relates to the technical field of electric fans, and more specifically, to an electric fan with a seat body that can be easily changed. Background Art

[0002] Electric fan, also known as fan, is a household appliance that accelerates the circulation of air. The main principle of electric fan making people feel cool is that the motor drives the fan blades to rotate, thereby accelerating the air circulation around the human body. The speed at which water evaporates from the pores of the skin is accelerated. Since the heat taken away by the evaporation process increases, people feel cool.

[0003] The electric fan is composed of a fan head, blades, a mesh cover and a control device, and is widely used in homes, classrooms, offices, shops, hospitals, hotels and other places. Although the existing electric fans can accelerate the air flow, they are usually fixed on the base of the electric fan. When the base needs to be replaced, corresponding tools are required for disassembly and installation, which makes it very troublesome to replace the base of the electric fan and is very inconvenient to use. Therefore, it is necessary to improve it. Utility Model Content

[0034] By setting the card blocks 4, the two card blocks 4 can play a fixing role between the shell 1 and the support rod 2 when they are located inside the card slots 3. The operator can drive the two card blocks 4 to move away from each other by making the two connecting plates 7 move away from each other, thereby making the two card blocks 4 disengage from the inside of the card slots 3, thereby releasing the fixing effect between the shell 1 and the support rod 2. The operator can adjust the overall height of the shell 1 by inserting the card blocks 4 into the inside of the card slots 3 at different positions.

[0035] The disassembly mechanism includes:

[0036] A fixed shaft 8, the front end of which is fixedly connected to the back side of the housing 1;

[0037] The inner wall of the rotating rod 9 is movably connected to the outer surface of the fixed shaft 8, and a handle 10 is fixedly installed on the outer surface of the rotating rod 9. Both ends of the rotating rod 9 are hinged with hinged rods 11, and the other end of the hinged rod 11 is hinged to the rear side of the connecting plate 7.

[0038] The operator can rotate the handle 10 so that the handle 10 drives the rotating rod 9 to rotate around the fixed shaft 8 as the axis, thereby enabling the hinged rod 11 to drive the connecting plate 7 to move.

[0039] A support frame 12 is fixedly installed at the bottom of the support rod 2 , and a base 13 is fixedly installed at the bottom of the support frame 12 .

[0040] By providing the support frame 12 , the support frame 12 can support the support rod 2 .

[0041] Among them, the base 13 has a rotating shaft 14 movably sleeved inside, the top of the rotating shaft 14 passes through the base 13 and extends to the top of the base 13, the top of the outer surface of the rotating shaft 14 is fixedly sleeved with a gear 19, and the outer surface of the rotating shaft 14 is fixedly sleeved with a disc 15 located inside the base 13, and the outer surface of the disc 15 is movably connected to the inner surface of the base 13.

[0042] When the rotating shaft 14 rotates, the disc 15 will be driven to rotate.

[0043] A round block 16 is fixedly mounted on the upper surface of the disc 15 , and a push-pull rod 17 is movably sleeved on the outer surface of the round block 16 .

[0044] By providing the round block 16 , when the disc 15 rotates, the round block 16 can drive the push-pull rod 17 to move.

[0045] A movable plate 18 is hingedly connected to the outer side of the push-pull rod 17 , and the outer surface of the movable plate 18 is movably sleeved with the inner surface of the base 13 .

[0046] By providing the movable plates 18 , the three movable plates 18 can increase the overall stability of the housing 1 after moving outward, so that the housing 1 is not easy to fall over when shaking.

[0048] The operator can pull the round rod 21 to the left, thereby driving the tooth plate 20 to move to the left, so that the tooth plate 20 can drive the gear 19 to rotate.

[0049] The working principle and use process of this utility model:

[0050] When the support rod 2 needs to be replaced as a whole, first, by turning the handle 10, the handle 10 drives the rotating rod 9 to rotate around the fixed axis 8, and then the rotating rod 9 can drive the hinged rod 11 to move, so that the hinged rod 11 can drive the two connecting plates 7 to move away from each other, and then the two clamping blocks 4 move away from each other, so that the clamping block 4 is disengaged from the inside of the clamping slot 3, and the fixing effect between the shell 1 and the support rod 2 can be released, so that the operator can replace the support rod 2 as a whole. The operator can adjust the height of the shell 1 as a whole by inserting the clamping block 4 into the inside of the clamping slot 3 at different positions.

[0051] The operator pulls the round rod 21 to the left, so that the round rod 21 drives the tooth plate 20 to move. Since the outer surface of the tooth plate 20 is meshed with the outer surface of the gear 19, the tooth plate 20 can drive the gear 19 to rotate, and then the gear 19 drives the rotating shaft 14 and the disk 15 to rotate, so that the round block 16 can drive the push-pull rod 17 to move, so that the three push-pull rods 17 can simultaneously push the three movable plates 18 to move outward, thereby improving the overall stability of the shell 1.
