Description

Technical Field

[0001] The present application relates to an oscillating fan, and in particular to an anti-winding oscillating fan. Background Art

[0002] Existing fans can only rotate within a certain range of angles and cannot achieve 360-degree rotation. Obviously, a fan with 360-degree rotation can provide smoother airflow and better ventilation. However, achieving 360-degree rotation requires preventing wire entanglement, which is a technical pain point in existing technology.

[0003] Therefore, how to design an oscillating fan so as to prevent winding is a problem that needs to be solved urgently in the prior art. Utility Model Content

[0004] The purpose of this application is to design an anti-winding oscillating fan. By setting a wire-passing shaft, the head assembly and the base can be rotated arbitrarily without winding. In addition, the oscillating fan of this application can achieve simultaneous reversal while shaking, which effectively improves the defect of the limited air supply angle of the circulating fan.

[0005] The present application relates to an anti-winding oscillating fan, comprising a base and a head assembly, wherein a first synchronous motor is provided on the base, and the head assembly rotates relative to the base through the first synchronous motor, and the output shaft of the first synchronous motor is connected to a driving gear, and the driving gear is connected to a driven gear, and a bearing is provided in the driven gear, and a wire-passing rotating shaft is provided at the center of the bearing.

[0006] In which, the driven gear can be set at an angle of 20-40 degrees; it can also include a chassis and a second synchronous motor, and the base rotates relative to the chassis through the second synchronous motor; a synchronous motor fixing plate can be fixedly connected to the base, and the second synchronous motor can be fixedly set on the synchronous motor fixing plate; a shaft sleeve can be provided between the base and the chassis, and the base can rotate relative to the chassis through the shaft sleeve; the output shaft of the second synchronous motor is connected to the eccentric member, and the eccentric member is connected to the shaft sleeve through a connecting rod; a support ring can also be provided between the base and the chassis; a circular hole can be provided on the support ring, and a ball is provided in the circular hole; the driven gear can be connected to the machine head bracket, and the machine head assembly is connected to the machine head bracket.

[0007] This application uses a bearing with a through-line rotating shaft to enable the head assembly and the base to rotate arbitrarily without winding. By designing two synchronous motors that drive the base and the head assembly to rotate respectively, the fan can change various angles during the shaking process, forming a more three-dimensional air supply effect and improving the user experience. This application provides users with more practicality through the left and right shaking mechanism. It can not only adjust the air supply direction at multiple angles, but also meet different needs by separately controlling the combination of two shaking synchronous motors.

[0014] To make the purpose, technical solutions and advantages of this application more clear, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of this application can be combined with each other in any way.

[0015] According to the present application, an anti-winding oscillating fan includes a chassis 30, a base 20 and a head assembly, wherein the base 20 is arranged on the chassis 30, and the head assembly can rotate relative to the base 20. A first synchronous motor 21 is provided on the base 20, and the output shaft of the first synchronous motor 21 is connected to the driving gear 22, and the driving gear 22 and the driven gear 23 are engaged with each other. A base cover 24 is provided on the base 20, and the driving gear 22 and the driven gear 23 can be arranged in the base cover 24, and the driving gear 22 drives the driven gear 23 to run in the base cover 24. Preferably, the rotating shaft of the driven gear of the present application is designed to have an angle of 20-40 degrees with the horizontal plane, so that the contact surface between the head assembly and the base forms an angle of 20-40 degrees with the horizontal plane, preferably 30 degrees. This allows the head assembly of the present application to rotate in an inclined plane, forming a more three-dimensional air supply effect, thereby enhancing the user experience.

[0016] The driven gear 23 is connected to the machine head bracket 13. The driven gear 23 and the machine head bracket 13 are fixed by screws. The machine head bracket 13 moves with the driven gear 23. The machine head assembly is fixed to the machine head bracket 13. The driven gear 23 drives the machine head assembly to rotate around the center of the driven gear. A bearing 27 and a wire-passing shaft 29 are provided between the driven gear 23 and the base cover 24. The wire-passing shaft 29 is set at the center of the bearing 27, and an electric wire 290 is provided inside the wire-passing shaft 29. The bearing 27 is set between the driven gear 23 and the base cover 24, and the driven gear 23 rotates around the center of the bearing. The bearing assembly of the present application can realize 360-degree rotation between the machine head assembly and the base. Since the electric wire is led out through the inside of the wire-passing shaft 29, and the wire-passing shaft 29 is set at the center of the bearing, the wire winding phenomenon will not occur.

[0017] More preferably, the base 20 can also be arranged to be rotatable relative to the chassis 30. Specifically, as Figure 1 As shown, a shaft sleeve 35 can be provided between the base 20 and the chassis 30, allowing the base 20 to rotate relative to the chassis 30 with the aid of the shaft sleeve 35. A synchronous motor fixing plate 36 is fixedly connected to the base 20, and the shaft sleeve 35 is fixedly provided on the synchronous motor fixing plate 36. A second synchronous motor 31 is also fixedly provided on the synchronous motor fixing plate 36. The output shaft of the second synchronous motor 31 is connected to the eccentric member 32, and the eccentric member 32 is connected to the shaft sleeve 35 via a connecting rod 33. In the present application, the eccentric member is driven to rotate by the second synchronous motor, thereby driving the crank connecting rod and the shaft sleeve to rotate relative to the chassis. Preferably, a support ring 34 can also be provided between the base 20 and the chassis 30, and the support ring 34 is preferably a POM support ring. A ball bearing is fixed to the base, and a slide groove is provided in the support ring, and the ball bearing can move within the slide groove. By designing two synchronous motors to respectively drive the rotation of the base and the head assembly, the present application allows the fan to change various angles during the shaking process, creating a more three-dimensional air supply effect and improving the user experience.
