Description

Technical Field

[0001] The utility model relates to the field of electric fans, in particular to a structure which can enable a fan head to automatically shake left and right and swing up and down at the same time. Background Art

[0002] As an indispensable appliance for family life, electric fans are becoming more and more popular with the advancement of technology. The fan usage scenarios have been enriched and the functions of fans have been optimized. From the most basic floor fans to air circulation fans, cooling fans, water-cooled tower fans, etc., different types of fans have their own advantages. Among them, floor fans are the most commonly used fans. The main features of floor fans are large air volume and low noise. In the hot summer, they have good effects on indoor ventilation, heatstroke prevention and cooling, and environmental improvement. Floor fans can be used by placing them on the ground steadily. They are safe, relatively cheap, and easy to use. Floor fans usually have the functions of multi-speed adjustment and left and right up and down adjustment angles. However, most floor fans on the market can only be adjusted left and right or up and down separately, and cannot be adjusted or swung at the same time. They have the disadvantages of limited blowing range and single function. They are not friendly to special users who cannot blow directly, and cannot be well matched with air conditioners, heaters, purifiers and other electrical appliances, and cannot meet the needs of different groups of people at the same time. Summary of the invention

[0003] The purpose of the utility model is to provide a structure that can make the fan head automatically shake left and right and swing up and down at the same time in view of the defects and shortcomings of the prior art. The structure is scientific and reasonable, the assembly is simple and quick, the shaking head has a wide air supply range, and it can be used alone or in conjunction with other electrical appliances.

[0004] In order to solve the problems existing in the background technology, the utility model adopts the following technical solutions: a structure that can make the fan head automatically shake left and right and swing up and down at the same time, including a fan blade mesh cover, a head assembly, a fixed seat, a supporting shaft, and a head housing. The fan blade mesh cover is fixedly connected to the head assembly by threads. The head assembly is composed of a head, a left and right shaking motor, a left and right first rotating arm, a left and right second rotating arm, a rotating seat, an up and down swinging motor, an upper and lower first rotating arm, and an upper and lower second rotating arm. One end of the left and right first rotating arm is vertically fixedly connected to the rotor of the left and right shaking motor, and the other end is connected to one end of the left and right second rotating arm in an overlapping and rotatable manner. The other end of the left and right second rotating arm is fixed on the rotating seat, and the rotating seat is installed and fixed in the connecting hole of the fixed seat. The swivel seat is rotatably connected to the supporting shaft, and the supporting shaft is fixedly connected to the fan support rod. One end of the upper and lower first rotating arms is vertically fixedly connected to the rotor of the upper and lower swing motor, and the other end is rotatably connected to one end of the upper and lower second rotating arms in an overlapping manner, and the other end of the upper and lower second rotating arms is fixed to the rotating arm hole on the outside of the fixing seat. The fixing seat is a U-shaped structure as a whole, with connecting holes and motor mounting holes at the bottom, and shaft holes and fixing columns on both sides of the upper part. The left and right shaking motor is installed below the motor mounting hole, and its rotor protrudes upward through the motor mounting hole. The head assembly can be rotatably connected up and down by cooperating with the shaft holes above the two sides of the fixing seat through the cylindrical shafts arranged on both sides of the head. The fixing seat is fixedly connected to the fixing holes on both sides of the head shell through the fixing columns above the two sides.

[0005] Working principle of the utility model: the utility model drives the left and right first rotating arms to rotate through the rotor of the left and right shaking motor, and the left and right first rotating arms then drive the left and right second rotating arms to rotate. Since the other ends of the left and right second rotating arms are fixed on the rotating seat, the rotating seat rotates with the supporting shaft as the axis. Moreover, since the left and right shaking motors and the rotating seat are both fixedly mounted on the fixed seat, the rotating seat drives the fan head to shake left and right as a whole. The rotor of the left and right shaking motor rotates one circle to make the fan head rotate back and forth left and right through a stroke. When the left and right first rotating arms rotate to overlap with the left and right second rotating arms to form the shortest straight line, the fan head is at the far left or right at this time. When the left and right first rotating arms rotate to overlap with the left and right second rotating arms to form the longest straight line, the fan head is at the far right or left at this time, thereby realizing the function of the fan head automatically shaking left and right. Similarly, the rotor of the up and down swinging motor drives the upper and lower first rotating arms to rotate. The first upper and lower rotating arms then drive the second upper and lower rotating arms to rotate. Since the other ends of the second upper and lower rotating arms are installed and fixed on the rotating arm holes outside the fixing seat, and since the fixing seat cannot rotate up and down, the up and down swinging motor drives the head assembly as a whole to rotate up and down with the cylindrical axis as the axis. The rotor of the up and down swinging motor rotates one circle to cause the fan head to swing back and forth up and down through a stroke. When the first upper and lower rotating arms rotate to overlap with the rotation of the second upper and lower rotating arms to form a shortest straight line, the fan head swings up and down to the highest point. When the first upper and lower rotating arms rotate to overlap with the rotation of the second upper and lower rotating arms to form a longest straight line, the fan head swings up and down to the lowest point, thereby realizing the function of automatic up and down swinging of the fan head. When the fan head of the utility model shakes left and right and up and down, the two structures do not interfere with each other, so that the fan head can swing up and down while shaking left and right, or can shake left and right or up and down alone.

[0006] After adopting the above technical scheme, the utility model has the following beneficial effects: the structure of the utility model can make the fan head automatically swing up and down while shaking its head left and right, realizing multi-angle rotation air supply up, down, left and right, with a large air supply angle and a wide range, which can circulate the wind at all angles of the space to the greatest extent, and is easy to adjust. It can automatically blow upwards when adjusted to a specified position, avoiding the problem that ordinary fans can only blow at people. It is more friendly to special users such as the elderly and children who cannot blow directly, and can also be used in conjunction with home appliances such as air conditioners, humidifiers, and purifiers to better circulate indoor air.

[0007] Furthermore, the structure that can make the fan head automatically shake left and right and swing up and down at the same time also includes a control switch, which is installed in the upper opening of the head shell and is electrically connected to the head assembly.

[0008] After adopting the above technical scheme, the utility model can adjust the three modes of the fan head through the control switch button arranged on the upper part of the head shell: shaking head left and right, swinging up and down, and shaking head left and right and swinging up and down at the same time. It can also be controlled by a remote control or a mobile phone.

[0009] Furthermore, decorative covers are provided in the buckles in the buckle holes on both sides of the head shell.

[0010] After adopting the above technical solution, the decorative cover of the utility model can cover the connecting parts installed between the fixing column of the fixing seat and the fixing hole of the head shell, preventing the connecting parts from being exposed for a long time and corroding, maintaining the connection stability, and being practical and beautiful.

[0011] Furthermore, a support frame is provided on the head assembly, the upper front of the support frame is in a "C" shape, and the lower side is in an "L" shape. The fan blade mesh cover is also equipped with a buffer frame, which is in an "L" shape and its vertical support is curved in an arc shape. The support frame and the buffer frame are installed and fixedly connected.

[0012] After adopting the above technical scheme, the support frame of the utility model surrounds and supports the bottom of the head assembly along the middle and rear part, and by connecting with the buffer frame, it can strengthen the support for the middle and rear side of the head assembly, and at the same time can buffer the vibration generated when the motor rotates.

[0013] Furthermore, a support plate is provided below the head assembly, and an arc-shaped groove is provided above the support plate, which is installed on the rear side of the fan blade mesh cover.

[0014] After adopting the above technical scheme, the support plate provided in the utility model can strengthen the support for the bottom of the head assembly. At the same time, when assembling the fan head, the support plate installed on the rear side of the fan blade mesh cover can be used as a support point to avoid displacement during installation, which has the beneficial effects of good structural stability and easy and quick assembly.
