Abstract
Description
Technical Field
[0001] The utility model relates to a fan, in particular to a multi-layer regular and irregular cross-type wind gathering net fan. Background Art
[0002] One of the core goals of designing a home or commercial fan is to provide adequate cooling. To achieve this goal, fan designers usually focus on how to increase air volume and pressure. In traditional designs, fans usually use a single mesh cover and a simple blade structure to generate air flow. However, this design often leads to increased noise and energy consumption while further increasing air pressure and air volume.
[0003] In the home and commercial fan markets, consumers have different demands for air volume and air pressure. Some people prefer strong winds to feel an instant coolness on a hot summer day, while others prefer gentle winds to create a comfortable atmosphere. However, traditional fan designs have certain limitations in meeting these different demands. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a multi-layer wind-collecting fan to solve the problems existing in the background technology.
[0005] The utility model multi-layer wind gathering fan is realized by the following technical scheme: including:
[0006] The wind gathering net cover has a multi-layer regular and irregular cross structure, wherein one end of the multi-layer wind gathering net cover is provided with a mounting cavity, and the end of the mounting cavity is provided with an air inlet cover;
[0007] An extended air duct is formed inside the multi-layer structure of the wind gathering net cover, wherein an air gathering port with a constricted structure is installed at the end of the multi-layer structure of the wind gathering net cover, and the wind pressure of the wind outflow is enhanced through the multi-layer structure of the wind gathering net cover and the air gathering port;
[0008] The fan assembly is fixedly arranged in the installation cavity, and the air inlet end of the fan assembly is connected to the air inlet cover of the multi-layer structure of the wind gathering mesh cover.
[0009] As a preferred technical solution, the multi-layer structure of the wind gathering net cover includes at least two wind gathering nets designed to be superimposed on each other, and the at least two wind gathering nets include a first wind gathering net and a second wind gathering net;
[0010] The installation cavity is arranged at one end of the first wind gathering net, and the second wind gathering net is placed at the other end of the first wind gathering net, and the first wind gathering net and the second wind gathering net are installed with each other to form the extended air duct.
[0011] As a preferred technical solution, the other ends of the first wind gathering net and the second wind gathering net are provided with wind guide plates, and the number of wind guide plates of the second wind gathering net is greater than the number of wind guide plates of the first wind gathering net.
[0012] As a preferred technical solution, the fan assembly includes a drive motor and a fan blade;
[0013] The fan blades are installed on the output shaft of the driving motor, and the driving motor is fixed in the installation groove of the first wind gathering net. The fan blades are driven to rotate by the driving motor, thereby achieving the effect of blowing air.
[0014] As a preferred technical solution, the air gathering port is installed at the other end of the second air gathering net.
[0015] The beneficial effects of the utility model are:
[0016] 1. The multi-layer structure of the wind gathering net cover of the utility model helps to concentrate wind force, so that the wind passes through the fan more concentratedly; through the interaction of the first wind gathering net and the second wind gathering net, the wind duct formed can further guide and concentrate the wind flow, which helps to improve the wind pressure and air volume of the whole system.
[0017] 2. The first wind gathering net and the second wind gathering net of the utility model have different numbers of air guide plates. Such a design helps to adjust the wind pressure in stages, so that the wind force is further strengthened before being blown out of the fan, thereby maintaining a higher wind speed at a farther distance from the fan.
[0018] 3. The air gathering port of the utility model is reduced in size, which can further increase the wind pressure and wind speed, so that the air supply distance of the fan is longer and the practicality of the fan is enhanced. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.
[0025] like Figure 1 and Figure 2 As shown, a multi-layer wind-gathering fan of the utility model comprises a wind-gathering mesh cover multi-layer structure, one end of the wind-gathering mesh cover multi-layer structure is arranged in a mounting cavity that plays a fixing role, and an air inlet cover 1 is arranged at the end of the mounting cavity; the wind duct is lengthened by the wind-gathering mesh cover multi-layer structure, and the wind pressure is enhanced by the wind-gathering mesh cover multi-layer structure, wherein an air gathering port is installed at the end of the wind-gathering mesh cover multi-layer structure, and the air outlet end of the air gathering port 6 is shrink-cut, thereby achieving the effect of increasing the wind pressure;
[0026] The fan assembly is fixedly arranged in the installation cavity, and the air inlet end of the fan assembly corresponds to the position of the air inlet cover 1 of the multi-layer structure of the wind gathering mesh cover.
[0027] The multi-layer structure of the wind gathering net cover includes a first wind gathering net 2 and a second wind gathering net 3;
[0028] The installation cavity is arranged at one end of the first wind gathering net 2, and the second wind gathering net 3 is placed at the other end of the first wind gathering net 2, and an air duct is formed by mutually installing the first wind gathering net 2 and the second wind gathering net 3.
[0029] Among them, the other end of the first wind gathering net 2 and the second wind gathering net 3 is provided with an air guide plate 4, and the number of the air guide plates 4 of the second wind gathering net 3 is greater than the number of the air guide plates 4 of the first wind gathering net 2, and the first air guide plates and the second air guide plates are regularly and irregularly cross-arranged; since the air guide plates 4 of the first wind gathering net 2 cannot completely correct the wind direction, the air guide plates 4 of the second wind gathering net 3 can re-correct the uncorrected wind.
[0030] In addition, the fan assembly includes a drive motor and a fan blade 5;
[0031] The fan blades 5 are installed on the output shaft of the driving motor, and the driving motor is fixed in the installation groove of the first wind gathering net 2. The driving motor drives the fan blades 5 to rotate, thereby achieving the effect of blowing air.
[0032] In addition, the air gathering port 6 is installed at the other end of the second air gathering net 3, and the air outlet end of the air gathering port 6 is narrowed, so that the wind pressure can be increased, thereby improving the performance of the fan.
[0033] Here’s how it works:
[0034] The fan blades are directly mounted on the motor output shaft of the fan assembly; when the motor is started, the motor drives the fan blades to rotate, thereby generating wind flow; as the fan blades rotate, air begins to enter from the air inlet cover, and the inflowing air is concentrated to the center of the fan; the air flow enters the first air gathering net, and the air processed by the first air gathering net further enters the second air gathering net;
[0035] Since the number of air guide pieces of the second air gathering net is greater than that of the first air gathering net, it can provide a stronger air gathering effect, thereby further enhancing the directionality of the wind flow and increasing the wind pressure;
[0036] After passing through the second air gathering net, the air is finally discharged through the air gathering outlet; the air gathering outlet is in the form of a contraction, and the area of the air outlet is smaller than that of the air inlet, so that the air flow rate through the air gathering outlet is increased.
[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
