Description

Technical Field

[0001] The utility model mainly relates to a stable swing rotation structure of a tower fan.

Background Art

[0002] A tower fan is a new type of fan with a columnar shape. Due to its unique columnar shape, the tower fan requires a relatively small floor area when placed, and thus is increasingly favored by consumers. However, precisely because the tower fan has a relatively long body and a relatively small floor area of its chassis, the stability of the tower fan is not good.

[0003] A tower fan generally includes a body with an air outlet structure inside and a base that bears the weight of the body. A swing device is installed inside the base. As an important component of the tower fan, the swing device is installed inside the base and drives the body to rotate during the operation of the tower fan to achieve oscillating air blowing; the swing device generally includes a transmission wheel and a motor. The body is provided with a shaft rod connected to the transmission wheel, and the motor drives the transmission wheel to drive the body to rotate. However, since the diameter of the shaft rod connected to the base is small, the contact area between the body and the base is small, and the stress area during the rotation of the body relative to the base is small, which easily causes the body of the tower fan to shake and affects the overall stability of the tower fan. Therefore, how to improve the stability during the rotation of the body has become the research direction for us.

Content of the Utility Model

[0004] To solve at least one of the above problems, the utility model proposes a new structural solution. The stable swing rotation structure of a tower fan adopts the following technical solutions:

[0007] The guide rail frame is arranged between the body and the base. The guide rail frame is provided with a number of through holes, and balls are placed in the through holes. The balls freely roll in the through holes, and when the body and the base are in contact, the balls simultaneously abut against the body and the base.

The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation of the present utility model.

[0020] The preferred embodiment provided by the present utility model is as follows: As Figures 1 to 3 shown, a tower fan smooth swing rotation structure includes a fuselage 1, a guide rail frame 2, and a base 3;

[0021] The base 3 has a fitting cavity 31. An electric motor 32 and a transmission gear 33 are provided in the fitting cavity 31. A gear 34 is installed at the rotating end of the electric motor 32 and is meshed with the transmission gear 33. A shaft rod 11 extends from the bottom of the fuselage 1, and the shaft rod 11 is connected to the transmission gear 33. The electric motor 32 drives the transmission gear 33 to drive the fuselage 1 to rotate;

[0022] The guide rail frame 2 is arranged between the fuselage 1 and the base 3. The guide rail frame 2 is provided with a plurality of through holes 21. Ball bearings 22 are placed in the through holes 21, and the ball bearings 22 freely roll in the through holes 21. The fuselage 1 and the base 3 are in contact, so that the ball bearings 22 are simultaneously in contact with the fuselage 1 and the base 3. The base 3 is provided with a connection hole 34 communicating with the fitting cavity 31. The shaft rod 11 passes through the connection hole 34 and is connected to the transmission gear 33. A bearing 35 is embedded in the connection hole 34, and the shaft rod 11 is connected to the bearing 35 to improve the smoothness of the rotation of the fuselage 1.

[0023] A concave cavity 12 is provided at the bottom of the fuselage 1. A convex platform 36 is provided on the upper end surface of the base 3. The convex platform 36 is inserted into the concave cavity 12. The shaft rod 11 is located at the center of the fuselage 1, and the shaft rod 11 is located in the concave cavity 12.

[0024] A limiting convex portion 13 extends in the concave cavity 12. The guide rail frame 2 is placed in the concave cavity 12 so that the limiting convex portion 13 is inserted into the inner diameter of the guide rail frame 2, so as to limit the movement range of the guide rail frame 2 in the concave cavity 12 through the limiting convex portion 13. Since the guide rail frame 2 is restricted by the limiting convex portion 13, it cannot translate in the concave cavity 12, but the guide rail frame 2 can rotate relative to the fuselage 1 to cooperate with the rotation of the fuselage 1. The convex platform 36 is provided with a guide sliding ring groove 37, and the ball bearings 22 of the guide rail frame 2 are in contact with the guide sliding ring groove 37.

[0025] To improve the stability of the body 1 during rotation, the present utility model proposes a smooth swing rotation structure for a tower fan, which includes a body 1, a guide rail frame 2, and a base 3; the body 1 and the base 3 are respectively provided with a concave cavity 12 and a convex platform 36, and the guide rail frame 2 is restricted between the body 1 and the base 3 through the connection of the concave cavity 12 and the convex platform 36; to limit the position of the guide rail frame 2, a circular limiting convex part 13 is provided in the concave cavity 12, and the diameter of the limiting convex part 13 corresponds to the inner diameter of the guide rail frame 2. After the limiting convex part 13 is inserted into the guide rail frame 2, it can limit the translation of the guide rail frame 2 in the concave cavity 12, so that the guide rail frame 2 can only rotate in the concave cavity 12; to reduce the friction between the body 1 and the base 3 during rotation, a row of rolling balls 22 is arranged around the guide rail frame 2. When the body 1 and the base 3 rotate relative to each other, the rolling of the rolling balls 22 assists the rotation of the two, and at the same time, the arrangement of the rolling balls 22 increases the support range of the base 3 for the body 1, with stronger stability. The rolling balls 22 are in an unrestricted state. The rolling balls 22 are held in the through holes 21 under the clamping of the base 3 and the body 1, and the rolling balls 22 can freely rotate in the through holes 21, so there will be no jamming situation and the rotation is smoother.
