Description

Technical Field

[0001] The invention relates to a bladeless fan, in particular to an adsorption-type anti-dumping bladeless fan. Background Art

[0002] The bladeless fan is also called an air multiplier. It can produce a natural and continuous cool breeze. Because it has no blades, it will not be covered with dust or accidentally hurt children. What is even more amazing is its unique shape. The appearance is both streamlined and refreshing, inspired by the air blade hand dryer. The bladeless fan blows air out from a narrow cut that rotates around a ring. Because air is a viscous fluid, the pressure decreases after the air is discharged from the outlet direction, and the relative pressure behind the circular wind ring is greater. The air will flow from high pressure to low pressure, and a large amount of air will pass through the circular wind ring, making the air flow rate faster.

[0003] The bladeless fan has won the favor of most people with its lightweight shape and scientific operating principle. However, because the bladeless fan is too light, it is easy to tip over and cause physical collision damage during daily use, so it is very important to design an adsorption-type anti-tip bladeless fan.

DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Example 1

[0027] An adsorption type anti-dumping bladeless fan, such as Figure 1-Figure 7As shown, it includes a shell 1, an air ring 2, an operation key 101, a motor 3 and a turbine blade 4. The air ring 2 is hollow and annular, and a narrow and long annular slit is opened on the inner side of the air ring 2. The top of the shell 1 is connected with the air ring 2. The shell 1 is provided with an operation key 101. The inner side of the shell 1 is provided with a motor 3 and a turbine blade 4. The motor 3 and the turbine blade 4 can blow air from the bottom of the bladeless fan to the annular air ring 2. It also includes a rotating rod 5, a rotating shaft 501 and an adsorption mechanism 6. The rotating shaft 501 is vertically fixed in the inner cavity of the shell 1 and can be rotated. The rotating rod 5 is fixedly connected to the rotating shaft 501 and extends out of the shell 1. The shell 1 is provided with a hole groove for the rotating rod 5 to move, and the adsorption mechanism 6 is arranged below the rotating shaft 501.

[0028] like Figure 1 and Figure 2 As shown, the adsorption mechanism 6 includes a wedge-shaped cross bar 601, a connecting rod 602, a piston 603, a suction cup 604 and a first return spring 605. The connecting rod 602 is rotatably connected to the lower side of the rotating shaft 501. The lower sides of both ends of the connecting rod 602 are respectively fixed with suction cups 604. The suction cups 604 are provided with holes. The piston 603 is slidably connected to the lower sides of both ends of the connecting rod 602 through the first return spring 605. The piston 603 can form a closed space with the suction cup 604 through the hole. A wedge-shaped cross bar 601 is arranged above the connecting rod 602, and the wedge-shaped cross bar 601 is fixed to the rotating shaft 501.

[0029] When the bladeless fan is needed, the motor 3 is turned on, and the motor 3 will drive the turbine blades 4. The turbine blades 4 will draw air from the lower part of the outer shell 1 and blow the air into the hollow air ring 2. The air is blown out through the annular slits opened in the air ring 2. Due to the pressure difference between the front and rear sides, a large amount of air on the rear side will pass through the air ring 2 to form a larger air volume. When it is necessary to increase the overall stability of the bladeless fan, the adsorption mechanism 6 can be used to achieve this. By pulling the rotating rod 5 to rotate the rotating shaft 501, the rotating shaft 501 will drive the wedge-shaped cross bar 601 to rotate. Due to the special shape of the wedge-shaped cross bar 601, the wedge-shaped cross bar 601 will push the connecting rod 602 and the piston 603 to move downward successively when rotating. When the connecting rod 602 moves downward, it will squeeze the suction cups 604 located at both ends of the connecting rod 602, so that the suction cups 604 are compressed. At the same time, the downward movement of the piston 603 will block the hole above the suction cup 604, so that the inside of the suction cup 604 becomes a closed space, forming an air pressure difference with the outside world, and the suction cup 604 can be adsorbed on the ground or on the table, so that the bladeless fan can be kept stable to the greatest extent and prevented from tipping over.

[0030] Example 2

[0031] On the basis of Example 1, Figure 3As shown, it also includes a bottom support mechanism 7 that can expand the bottom area to increase stability. The bottom support mechanism 7 includes a shaft disc 701, a support rod 702, a limit ring 703 and a movable block 704. The shaft disc 701 is fixedly connected to the lowermost side of the rotating shaft 501. Four support rods 702 are rotatably connected to the shaft disc 701. The other ends of the support rods 702 are respectively fixedly connected to four movable blocks 704. The limit ring 703 is fixedly connected to the lower part of the outer shell 1. The support rod 702 fixes the movement trajectory through the shaft disc 701 and the limit ring 703. The movable block 704 can form a complete circular bottom surface with the lower part of the outer shell, and can also be pushed out by the support rod 702 to increase the area of ​​the bottom surface, thereby increasing the stability of the bladeless fan.

[0032] When the rotating rod 5 is pulled to rotate the rotating shaft 501, the shaft disk 701 at the bottom of the rotating shaft 501 will also rotate accordingly, thereby triggering the bottom support mechanism 7. One end of the support rod 702 is rotatably connected to the shaft disk 701, and the other end is fixed to the movable block 704. The movement trajectory of the support rod 702 is determined by the limit ring 703 in the middle. Therefore, when the shaft disk 701 rotates, the support rod 702 pushes the movable block 704 out, thereby increasing the bottom area of ​​the bladeless fan, thereby increasing the stability of the bladeless fan.

[0033] like Figure 4 and Figure 5 As shown, it also includes a support mechanism 8 from which a bracket 803 can be extended from the side, and the support mechanism 8 includes a limiting plate 801, a slide plate 802, a bracket 803, a hinge shaft 804, a limiting pin 805 and a second return spring 806. The limiting plate 801 is fixedly connected to the upper side of the rotating shaft 501, and the limiting plate 801 is provided with a slot hole. A slide plate 802 is arranged below the limiting plate 801, and the slide plate 802 is rotatably connected to the rotating shaft 501. The slide plate 802 is provided with four slide grooves, and the four brackets 803 are connected to the slide plate 803 through the slide grooves. 2 sliding connection, each bracket 803 is divided into two parts and connected by a hinge shaft 804, the hinge shaft 804 allows the bracket 803 to be bent, and a vertical cylindrical block is provided on the inner side of the bracket 803, the bracket 803 is slidably connected to the limiting plate 801 through the cylindrical block, and the limiting pin 805 is slidably connected to the housing 1 through a second return spring 806, and the limiting pin 805 is in contact with the bracket 803. When the bracket 803 is extended, the bracket 803 can be bent at the hinge shaft 804 to make it contact with the ground, thereby playing a stabilizing role.

[0034] The rotation of the rotating shaft 501 triggers the supporting mechanism 8 at the same time. The rotation of the rotating shaft 501 will drive the limiting plate 801 to rotate. The hole groove on the limiting plate 801 will drive the bracket 803 to move on the slide rail plate 802, that is, the bracket 803 will slide outward. When sliding to a certain position, the limiting pin 805 will push the bracket 803 to bend at the hinge shaft 804, so that the bracket 803 can contact the ground to form better stability.

[0035] like Figure 6As shown, it also includes a locking mechanism 9 that can fix the rotating rod 5. The locking mechanism 9 includes a wedge-shaped stopper 901, a buckle 902 and a third return spring 903. The buckle 902 is fixed to the housing 1. The wedge-shaped stopper 901 is slidably connected to the buckle 902. The third return spring 903 is connected between the wedge-shaped stopper 901 and the buckle 902. When the rotating rod 5 moves, it will contact the wedge-shaped stopper 901 and compress the third return spring 903 through the wedge-shaped stopper 901.

[0036] When the rotating rod 5 rotates to the corresponding position, it can be fixed by the locking mechanism 9, and the rotating rod 5 pushes the wedge-shaped stopper 901 to move upward, and then the wedge-shaped stopper 901 is reset by the third reset spring 903, and the rotating rod 5 is fixed.

[0037] like Figure 7 As shown, it also includes a wire capstan 10, which is arranged in the inner cavity of the shell 1 and is rotatably connected to the shell 1. The wires connected to the motor 3 are wound around the wire capstan 10, and the shell 1 is provided with a hole groove for the wire capstan 10 to rotate.

[0038] like Figure 4 and Figure 5 As shown, it also includes a support plate 11, which is rotatably connected to the bracket 803. When the bracket 803 contacts the ground, the support plate 11 provides a support surface, which plays a positive role in the stability of the bladeless fan.

[0039] In the inner cavity of the housing 1, a wire winch 10 is also provided accordingly, which can store the wires well, conveniently and quickly. A support plate 11 is provided at one end of the bracket 803, which can increase the contact area of ​​the bracket 803 when it contacts the ground, and better enhance the stability.

[0040] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
