Description

Technical Field

[0001] The utility model relates to the technical field of fans, and particularly relates to a portable fan installation structure. Background Art

[0002] A fan is a driven fluid machine that relies on the input mechanical energy to increase the gas pressure and transport the gas. The application range of fans is very wide, such as for ventilation, dust removal and cooling in factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induced draft in boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household electrical appliances; drying and selection of grains; air source in wind tunnels and inflation and propulsion of hovercrafts, etc.

[0003] Existing fans do not have a modular design during use and are inconvenient for installing each part. For example, a fan disclosed in the patent application No. CN201520139451.3. Such existing fans do not have a modular design and a portable installation structure. The non-modular design means that the various components of the fan are usually fixed together, making it difficult to disassemble or replace them individually. This not only increases the complexity of installation but also makes it more difficult when maintenance or component replacement is needed. Without a portable installation structure, the fan may require a large amount of modification or customization when facing different usage scenarios to adapt to the installation space or conditions, which undoubtedly increases the usage cost and complexity. Due to the non-modular design of the fan, once a failure occurs, it may be necessary to disassemble and inspect the entire fan, increasing the difficulty and time cost of maintenance. For application scenarios that require an increase in air volume, the non-modular design may make it difficult or impossible to expand the capacity of the fan, thus limiting its application range.

[0004] Therefore, it is necessary to invent a portable fan installation structure to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a portable fan installation structure to solve the problems in the prior art that there is no modular design during use and it is inconvenient to install each part.

[0009] Preferably, clamping blocks are fixedly installed on the four sides of the outer wall of the protective net, and clamping grooves that are clamped and matched with the clamping blocks are opened at the four sides of the inner wall of the outer covering shell near the port.

[0010] Preferably, a reciprocating lead screw is installed in the middle of the two adjusting grooves. One end of the reciprocating lead screw is installed with a motor. The motor is located on one side of the outer wall of the base. A rotating shaft is installed at the connection of the reciprocating lead screw and one side of the inner wall of the adjusting groove.

[0011] Preferably, a moving seat is installed at the bottom end of the bottom column. The moving seat is installed on the reciprocating lead screw in the adjusting groove. A connecting rod is fixedly installed in the middle of one side of the outer wall of the bottom column. A docking rod is installed in the middle of the other side of the outer wall of the bottom column. The two ends of the connecting rod and the docking rod are attached to form a sleeve shape. The edge of the joint surface of the docking rod and the connecting rod is fixed by a second bolt.

[0012] Preferably, a support rod is welded to one side of the middle of the connecting rod. A support seat is installed at the end of the support rod. An auxiliary groove that is slidably connected and matched with the bottom end of the support seat is opened in the middle of the surface of the base.

[0014] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0015] For this portable fan installation structure, through modular design, the fan body and components such as the outer covering shell are detachable, which is convenient for carrying and transportation. The design of the adjusting groove and the bottom column allows users to adjust the height and angle of the fan according to needs, increasing the flexibility of use. The design of the support rod and the support seat enhances the stability of the fan, preventing the fan from shaking due to excessive wind force during operation. The design of the mounting plate and the screw enables the fan to be easily fixed on the ground or other planes. The installation process is simple and fast. The entire installation structure is designed compactly, and the connection between components is tight, effectively saving space and facilitating installation and use in a limited space. Due to the adoption of modular design and easily replaceable components, when the user needs to replace or upgrade the fan, only the corresponding components need to be replaced, reducing the maintenance cost.

[0026] The working principle of this utility model:

[0027] Refer to the attached instructions Figures 1-5, for this type of portable fan installation structure, when in use, first, the fan body 1 is the core component responsible for generating wind. The outer casing 2 protects the fan body 1 and provides a stable operating environment. At the same time, it is connected to the air diffuser 3 to ensure smooth air flow. The design of the air diffuser 3 makes the outlet air speed more uniform, while increasing the air volume and range. The protective net 4 is installed inside the air diffuser 3 to prevent large particles or foreign objects from entering the fan interior and protect the fan from damage. The sealing ring 201 and the first bolt 202 ensure the sealing between the outer casings 2 to prevent air leakage. The adjustment groove 6 and the reciprocating lead screw 601 allow the bottom column 7 to adjust the distance horizontally. The motor 602 drives the reciprocating lead screw 601 to rotate, driving the bottom column 7 and the moving seat 701 thereon to move horizontally. The support rod 705 and the support seat 706 provide additional bottom stability for the fan to ensure that the fan does not shake when the air volume is large. The mounting plate 8 and the screw 801 provide a convenient installation method to fix the entire fan installation structure on the ground or other planes;

[0028] When using this device, first, tightly connect the two outer casings 2 through the sealing ring 201 and the first bolt 202 to ensure no air leakage. Install the protective net 4 inside the air diffuser 3 through the engaging block 401 and the engaging groove 402. Install the fan body 1 inside the outer casing 2 and fix it. Connect the power supply of the motor 602, control the rotation of the reciprocating lead screw 601, and adjust the height of the bottom column 7 until the desired position is reached. Fix the position of the bottom column 7 through the connecting rod 702, the docking rod 703, and the second bolt 704. Place the base 5 at the predetermined position and use the mounting plate 8 and the screw 801 to fix it on the wall, the ground, or other planes. Adjust the positions of the support rod 705 and the support seat 706 to ensure that the fan is stable and does not shake. Connect the power supply of the fan body 1, start the fan, and adjust the air speed and direction of the fan as needed.
