Description

Technical Field

[0001] The utility model relates to a fan, in particular to a quick-install double-layer floor fan. Background Art

[0002] As people's requirements for quality of life increase, the functionality and convenience of household appliances are increasingly valued, especially in the hot summer. As a common household cooling device, the performance and ease of use of electric fans directly affect the user experience. The common floor fans and floor fans on the market meet the basic needs of consumers to a certain extent, but with the diversification of application scenarios and the continuous changes in user needs, the floor fans in the existing technology have exposed some significant shortcomings and are difficult to adapt to the use of some scenarios.

[0003] Traditional floor fans currently on the market can usually only blow air in a single fixed direction, and the wind direction adjustment range is limited. For larger spaces or when users need to cover a wider wind area, existing floor fans cannot effectively meet this demand. Users often need to manually adjust the direction or position of the fan, which is not only cumbersome but also difficult to achieve precise adjustment, especially when users are at different heights, the air supply effect of the floor fan is significantly reduced. For example, when the user stands up, due to the low blowing angle of the traditional floor fan, the air supply range cannot effectively cover a higher position, resulting in the user being unable to enjoy continuous cool breeze. This limitation makes the traditional floor fan have certain limitations in application scenarios, and it is difficult to meet the needs of multi-angle and multi-directional air supply.

[0004] In addition, existing floor fans are also deficient in terms of mobility. Generally speaking, the bottom of traditional floor fans is not equipped with a device that facilitates mobility, such as a mobile support device such as casters. Therefore, when the user needs to move the fan between different locations, it is often necessary to carry it manually, which brings inconvenience to the user's operation, especially when moving in large places or between different rooms. This inconvenience is more prominent. At the same time, the overall structural design of traditional floor fans is relatively simple, lacking a convenient design that can be quickly disassembled and assembled. Users will also face certain operational complexities when carrying and storing, and it is difficult to adapt to the modern life's demand for the convenience of household appliances. Therefore, it is necessary to make further improvements to it. Utility Model Content

[0022] The following further specifically describes the utility model with reference to the drawings. A quick-installable double-deck floor fan includes a base frame 1, and casters 2 are installed at the front end of the base frame 1, and the rear end of the casters 2 and the base frame 1 is for floor support;

[0023] Two lower docking pipes 3 extending backward and upward are provided at the front end of the base frame 1, and two risers 4 are respectively docked with the two lower docking pipes 3. A connecting frame 5 is installed at the top of the two risers 4 to connect the two risers 4 into one body;

[0024] It also includes a lower fan group 7 connected and arranged between two riser pipes 4 through a quick-release device 6, and an upper fan group 8 arranged in a connecting frame 5. The lower fan group 7 and the upper fan group 8 perform vertical swinging displacement relative to the riser pipes 4 and the connecting frame 5 to adjust the pitching angle of the lower fan group 7 or the upper fan group 8, so as to expand the coverage area of the fan.

[0025] In one embodiment, the base frame 1 includes two horizontal pipes 11 distributed left and right. The lower docking pipe 3 is arranged at the front end of the horizontal pipe 11, and a rear pipe 12 is arranged behind the horizontal pipe 11. The rear pipe 12 is bent into a "C" shape, and the two free ends of the rear pipe 12 are docked with the horizontal pipe 11.

[0026] In one embodiment, a wheel plate 21 is further arranged between the lower docking pipe 3 and the horizontal pipe 11, and the casters 2 are laterally installed on the wheel plate 21.

[0027] In one embodiment, the included angle between the lower docking pipe 3 and the horizontal pipe 11 is 65 degrees - 75 degrees.

[0028] In one embodiment, a connecting pipe 9 is sleeved outside the lower docking pipe 3, and the left and right connecting pipes 9 are connected through a reinforcing pipe 91. The bottoms of the two riser pipes 4 are inserted into the connecting pipe 9 and connected to the lower docking pipe 3.

[0029] In one embodiment, the quick-release device 6 includes a connecting bolt 61 and a handwheel 62 arranged at one end thereof. Docking holes 63 are arranged on the side walls of the riser pipe 4 and the connecting frame 5, and the connecting bolt 61 passes through the docking hole 63 and is screwed with a screw hole 64 arranged on the side wall of the lower fan group 7 or the upper fan group 8.

[0030] Working principle: The base frame 1 of the present utility model has casters 2 installed at the front end and a floor support structure at the rear end. Through the arrangement of the casters, the user can easily push the fan to move. When the fan moves to a suitable position, the floor support structure at the rear end ensures the stability of the fan and avoids tilting or shaking. Therefore, when the user needs to adjust the position of the fan, they can easily operate, greatly improving the flexibility of use.

[0031] At the same time, the lower fan group 7 is connected between two riser pipes 4 through a quick-release device 6, and the upper fan group 8 is installed in the connecting frame 5. The design of the quick-release device enables the fan group to be quickly disassembled and assembled, facilitating maintenance and cleaning. Through the combination of the connecting bolt 61 and the handwheel 62, the user can quickly lock or unlock the fan group to achieve a firm connection of the upper and lower fan groups. This design simplifies the assembly process of the fan and is especially suitable for occasions that require frequent disassembly and assembly, improving the convenience of operation.

[0032] In addition, the upper fan group 8 and the lower fan group 7 of the utility model can be swung up and down relative to the vertical pipe 4 and the connecting frame 5. By adjusting the pitch angle of the fan group, the user can adjust the blowing angle of the fan according to different needs. For example, the user can adjust the lower fan group to blow upward to achieve wind coverage in the lower area; at the same time, the upper fan group can be adjusted to a larger pitch angle to cover a higher space. In this way, not only can a larger indoor space be covered, but the wind direction can also be adjusted according to different height requirements, so that users who are standing, sitting or moving can enjoy the cooling effect brought by the fan. This multi-angle adjustment function significantly improves the functionality of traditional floor fans.

[0033] Furthermore: the setting of the upper and lower double-layer fan groups allows the fan to blow air from two different heights and angles at the same time, further expanding the fan's coverage. Traditional floor fans can usually only be fixed in a single direction to blow air, and the coverage area is small, especially for larger rooms or open spaces, the air supply effect is limited. The double-layer fan structure of the utility model can supply air to different areas at the same time, achieving a more uniform wind speed distribution and a wider air supply coverage area, which is particularly suitable for scenes that require large-scale cooling.

[0034] In addition, the base frame 1 is composed of two horizontal tubes 11 and a rear tube 12. The rear tube is bent in a "C" shape and docked with the horizontal tube to form a stable support structure. This design not only enhances the stability of the base, but also ensures the overall balance of the fan during pitch adjustment or swinging, and is not easy to tip over. This stable structural design greatly improves the safety of the fan, especially when it needs to be used for a long time or operated on the move, it can ensure the smooth operation of the fan.

[0035] In addition, the quick release device 6 is operated by connecting bolts 61 and hand wheels 62. The user can quickly disassemble and assemble the fan assembly, the riser, and the connecting frame by manually rotating the hand wheels. This design not only simplifies the installation process, but also greatly improves the convenience during use. Especially when it needs to be transported or stored, the user can quickly complete the disassembly and assembly of the fan, reducing unnecessary operation steps.

[0036] Compared with the traditional technology, in this application, through the design of the upper and lower double-layer fan groups, the utility model can achieve air supply at different heights and angles. The user can adjust the pitch angle of the fan group as needed to meet the needs of different usage scenarios. This double-layer design significantly expands the air supply coverage of the fan, which is particularly suitable for large spaces or places that require multi-angle air supply. Therefore, this application not only overcomes the shortcomings of the existing floor-standing fans with a single air supply direction and inconvenient movement, but also greatly improves the practicality and ease of operation of the fan, so it can be widely promoted and used.

[0037] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and what is described in the above-mentioned embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements fall within the scope of the present utility model claimed.
