Description

Technical Field

[0001] The present invention relates to the technical field of fans, and in particular to a detachable and storable fan. Background Art

[0002] Traditional vertical electric fans have a certain height in actual use and are height-adjustable. Due to their high height, large rotation angle, and flexible and convenient use, they are widely loved and have an irreplaceable position in the fan field.

[0003] The use of standing fans is mostly seasonal. Generally, they are stored when the weather turns cold and are used again next year. However, current standing fans are usually inconvenient to store. Although the various components of existing standing fans can be disassembled separately, they are in bulk and need to be stored in bags or boxes. They cannot be stored separately as a whole. Summary of the invention

[0004] The object of the present invention is to provide a detachable and storable fan which is convenient for users to store as a whole and separately.

[0005] The present invention provides a detachable and storable fan, comprising:

[0006] The fan head comprises a fan head assembly, a fan blade detachably connected to a rotating shaft of the fan head assembly, a rear mesh cover detachably connected to the fan head assembly, and a front mesh cover buckled with the rear mesh cover;

[0007] A column detachably connected to the lower portion of the fan head;

[0008] a chassis, which is detachably connected to the bottom of the column;

[0009] When the fan is in the storage state, the rotating shaft of the fan head passes through the chassis, the rear mesh cover and the fan blades in sequence, and a nut is tightened to tighten the rotating shaft to fix the chassis, the rear mesh cover and the fan blades to the fan head, and the front mesh cover is buckled with the rear mesh cover.

[0010] The columns include an upper column and a lower column that are detachably connected. The top of the upper column is fixedly connected to the lower part of the fan head. When the fan is in the storage state, a fixing part fixes the lower column to the fan head assembly.

[0011] The fixing part comprises a main ring which is sleeved on the peripheral wall of the fan head assembly, and the main ring is provided with a sub-ring which is used for sleeved and fixed on the lower column.

[0012] Wherein, the main ring is an elastic ring whose tightness can be adjusted.

[0013] Among them, the lower column is a telescopic rod.

[0014] Wherein, the fan head assembly is movably connected with a handle.

[0015] The fan is also provided with a storage bag, and when the fan is in the storage state, the storage bag stores the fan.

[0016] The beneficial effects of the present invention are as follows: since the fan head assembly, fan blades, front mesh cover, rear mesh cover, column and chassis can all be manually disassembled and assembled, when the fan needs to be stored, first the fan head assembly, fan blades, front mesh cover, rear mesh cover, column and chassis are manually disassembled, and then the rotating shaft of the fan head is passed through the chassis, rear mesh cover and fan blades in sequence, and the rotating shaft is tightened with a nut to fix the chassis, rear mesh cover and fan blades to the fan head, and then the front mesh cover is buckled with the rear mesh cover. This has a simple structure and is easy to install and disassemble, making it convenient for users to store the fan as a whole. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The present invention is further described in conjunction with the following examples.

[0028] The present invention provides a detachable and storable fan, such as Figures 1 to 3 As shown, including:

[0029] The fan head 1 comprises a fan head assembly 11, a fan blade 12 detachably connected to a rotating shaft 13 of the fan head assembly 11, a rear mesh cover 14 detachably connected to the fan head assembly 11, and a front mesh cover 15 buckled with the rear mesh cover 14, wherein a power supply board 19, a control board 110 and a swing motor 111 are arranged inside the fan head assembly 11;

[0030] A column 2, which is detachably connected to the lower part of the fan head 1;

[0031] The chassis 3 is detachably connected to the bottom of the column 2 .

[0032] When the fan needs to be assembled, Figure 3 As shown, first, insert the rear mesh cover 14 into the threaded front end portion 16 of the fan head assembly 11, and screw the triangular nut 17 into the threaded front end portion 16 to fix the rear mesh cover 14 to the fan head assembly 11, then snap the fan blade 12 into the rotating shaft 13 of the fan head assembly 11, and fix the fan blade 12 to the rotating shaft 13 with the fan blade nut 18, and then buckle the front mesh cover 15 with the rear mesh cover 14, so that the assembly parts of the fan head 1 are completed; then use the locking piece 31 to fix the bottom of the column 2 to the middle of the chassis 3, and the column 2 is buckled and connected to the fan head 1, so that the entire fan is assembled, and the whole process is convenient and quick.

[0033] When the fan needs to be stored, the fan head assembly 11, the fan blades 12, the front mesh cover 15, the rear mesh cover 14, the column 2 and the chassis 3 can be manually disassembled. Figure 4As shown, the rotating shaft 13 of the fan head 1 is passed through the chassis 3, the rear mesh cover 14, the triangular nut 17 and the fan blade 12 in sequence, wherein the triangular nut 17 is screwed into the threaded front end 16 to fix the chassis 3 and the rear mesh cover 14 to the fan head assembly 11, and then the fan blade nut 18 is used to tighten the rotating shaft 13 to fix the fan blade 12 to the rotating shaft 13, and then the front mesh cover 15 is buckled with the rear mesh cover 14. This has a simple structure, is easy to install and disassemble, and is convenient for users to store the fan as a whole. When storing, all the structural components of the machine itself can be connected together to avoid losing accessories, and the storage area is small and easy to carry.

[0034] In this embodiment, the column 2 includes an upper column 21 and a lower column 22 that are detachably connected. The top of the upper column 21 is fixedly connected to the lower part of the fan head 1. Preferably, the lower column 22 is a telescopic rod, so that the fan can have a larger height adjustment range and increase the use scenarios. In order to store the disassembled lower column 22 as a whole, as shown in FIG. Figure 5 As shown, a fixing member 5 is provided to fix the lower column 22 to the fan head assembly 11. The fixing member 5 includes a main ring 51 sleeved on the peripheral wall of the fan head assembly 11. The main ring 51 is provided with a sub-ring 52 for sleeve-fixing the lower column 22. When folding, the main ring 51 can be sleeved on the peripheral wall of the fan head assembly 11 first, and then the sub-ring 52 can be sleeved on the lower column 22. Figure 6 In order to prevent the main ring 51 from not fitting tightly against the fan head assembly 11 and causing shaking, the main ring 51 is an elastic ring whose tightness can be adjusted, so that the main ring 51 fits tightly against the peripheral wall of the fan head assembly 11.

[0035] In this embodiment, Figure 6 and Figure 7 As shown, the fan further comprises a storage bag 6. When the fan is in the storage state, the storage bag 6 stores the fan for convenient storage. The fan head assembly 11 is movably connected with a handle, and the handle provided by the fan head assembly 11 is used to facilitate users to carry the fan after storage.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
