Description

Technical Field

[0001] The present application relates to the technical field of kitchen stoves, and in particular to a 360-degree rotating fan. Background Art

[0002] With the advancement of science and technology and the improvement of people's living standards, technological innovations in the field of household appliances are emerging in an endless stream. As an indispensable cooling device in daily life, the improvement of the performance and function of fans has become the focus of users' attention. In traditional oscillating air supply fans, the driving mechanism for realizing rotation is generally installed in the fan head, thereby driving the fan head to rotate while the base and bracket remain stable. However, the rotation of the fan is usually achieved by the drive motor. Installing the driving mechanism including the drive motor in the fan head increases the weight of the fan head. In order to ensure that the base and bracket can stably support the fan head, it is also necessary to increase the weight of the base and the supporting strength of the bracket. As a result, the larger the fan, the heavier it is, and it is not easy to move or carry during use. Summary of the Invention

[0003] The present application provides a 360-degree rotating fan to solve the problem that traditional fans install the rotating drive mechanism in the fan head, thereby increasing the weight and support strength of the base to achieve the stability of the fan head, which in turn causes the fan to be too heavy and difficult to move or carry during use.

[0004] In the first aspect, the present application provides a 360-degree rotating fan, comprising: a fan head, a bracket and a base, the bracket fixedly connects the fan head and the base, a fixed seat is rotatably installed under the base, the base includes a bottom plate and a shell, a drive motor is fixedly installed between the bottom plate and the shell, a through hole is opened on the bottom plate, the output shaft of the drive motor passes through the through hole, and a drive gear is fixedly installed on the output shaft of the drive motor, a driven gear with more teeth than the drive gear is fixedly installed on the fixed seat, the drive gear is meshed with the driven gear, and the bottom plate is rotatably installed on the top of the driven gear.

[0005] The above technical solution provided by the embodiment of the present application has the following advantages compared with the prior art:

[0006] The 360-degree rotating fan structure provided in the embodiment of the present application includes a fan head, a bracket and a base. The bracket fixedly connects the fan head and the base to achieve the installation of the fan. The base includes a shell and a base plate. A drive motor is fixedly installed between the shell and the base plate. A through hole is provided in the base plate. The output shaft of the drive motor passes through the through hole. A drive gear is fixedly installed on the output shaft of the drive motor. A fixed seat is rotatably installed below the base. A driven gear with more teeth than the drive gear is fixedly installed on the fixed seat. The drive gear is meshed with the driven gear. The rotation of the drive motor drives the drive gear to rotate. The rotation of the drive gear meshes with the driven gear, so that the drive gear rotates around the driven gear. The drive gear rotates around the driven gear and drives the drive motor to rotate synchronously. The drive motor is fixed to the base plate, thereby driving the base plate to rotate. The base plate is fixed to the bracket and the fan head, thereby driving the fan head to rotate. The meshing of the drive gear and the driven gear achieves 360-degree rotation of the fan. At the same time, the base plate is rotatably installed on the top of the driven gear, and the fixed seat supports the fan head, the bracket and the base through the driven gear. In the embodiment of the present application, by installing a 360-degree rotating drive mechanism on the base, the weight of the base is increased while not increasing the weight of the fan head, thereby increasing the overall stability of the fan.

DETAILED DESCRIPTION

[0019] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0020] The disclosure below provides many different embodiments or examples for implementing different configurations of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0021] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0022] In order to solve the technical problem that traditional fans install the rotation drive mechanism in the fan head, which requires increasing the weight and support strength of the base to achieve the stability of the fan head, and then causing the fan to be too heavy and difficult to move or carry during use, the present application provides a 360-degree rotating fan that can reduce the weight of the fan head while increasing the overall stability of the fan.

[0023] Figure 1A 360-degree rotating fan provided in an embodiment of the present application includes a fan head 101, a bracket 201 and a base 301. The bracket 201 fixedly connects the fan head 101 and the base 301 to achieve fan installation. The base 301 includes a shell and a base plate 302. A drive motor 501 is fixedly installed between the shell and the base plate 302. A through hole 3021 is provided on the base plate 302. The output shaft of the drive motor 501 passes through the through hole 3021, and a drive gear 502 is fixedly installed on the output shaft of the drive motor 501. A fixed base 401 is rotatably installed below the base 301. A driven gear 503 having more teeth than the drive gear 502 is fixedly installed on the fixed base 401. The drive gear 502 is meshed with the driven gear 503. The rotation of 1 drives the driving gear 502 to rotate, and the driving gear 502 rotates and engages with the driven gear 503, so that the driving gear 502 rotates around the driven gear 503. The driving gear 502 rotates around the driven gear 503 and drives the driving motor 501 to rotate synchronously. The driving motor 501 is fixed to the base plate 302, thereby driving the base plate 302 to rotate. The base plate 302 is fixed to the bracket 201 and the fan head 101, thereby driving the fan head 101 to rotate. The engagement of the driving gear 502 and the driven gear 503 realizes 360-degree rotation of the fan; at the same time, the base plate 302 is rotatably mounted on the top of the driven gear 503, and the driven gear 503 realizes the support of the fixed base 401 on the fan head 101, the bracket 201 and the base 301.

[0024] To facilitate replacement of the fixed base 301 or the driven gear 503, a mounting slot 402 is provided on the fixed base 301, and the driven gear 503 is installed in the mounting slot 402. To enhance the stability of the installation between the mounting slot 402 and the driven gear 503, a snap is provided on the side wall of the mounting slot 402, and a clamping block 5031 that matches the snap 4021 is fixed to the driven gear 503. When the driven gear 503 is installed in the mounting slot 402, the snap 4021 cooperates with the clamping block 5031 to secure the driven gear 503. At the same time, a protrusion 5032 is provided on the periphery of the driven gear 503. The sum of the thickness of the protrusion 5032 and the outer diameter of the gear shaft is consistent with the inner diameter of the mounting slot 402, thereby increasing the friction between the shaft and the mounting slot 402 and enhancing the stability between the driven gear 503 and the mounting slot 402.

[0025] To enhance the stability of the driven gear 503 within the mounting slot 402, a fixed shaft 403 may be fixedly mounted on the fixing base 401, and the driven gear 503 may be sleeved on the fixed shaft 403. The fixed shaft 403 positions the driven gear 503, thereby preventing the driven gear from shaking. The fixed shaft 403 may be fixedly mounted on the fixing base 401 at the location of the mounting slot 402. The fixed shaft 403 cooperates with the mounting slot 402 to secure the driven gear 503 between the mounting slot 402 and the fixed shaft 403, thereby preventing the driven gear 503 from rotating and shaking. To enhance the stability between the driven gear 503 and the fixed shaft 403, a limiting bar 4031 is provided on the fixed shaft 403 along its axis. The limiting bar 4031 increases the friction between the fixed shaft 403 and the driven gear, thereby enhancing the stability between the fixed shaft 403 and the driven gear 503.

[0026] In order to facilitate the maintenance or replacement of the driving motor 501 , a support column is fixedly mounted on the bottom plate 302 , and the driving motor 501 is fixedly mounted on the support column so that the driving motor 501 can be disassembled and installed.

[0027] To facilitate installation of the driven gear 503, an installation opening 4022 is provided on the side wall of the installation slot 402. The installation opening 4022 facilitates the operator to install the driven gear 503 into the installation slot 402. The installation opening 4022 is arranged opposite to the bayonet 4021 for convenience, making it easy to install the driven gear 503 with one hand.

[0028] In order to fix the installation position of the driven gear 503, a mounting hole 3022 is opened at the corresponding position of the base plate 302 and the fixed shaft 403, the fixed shaft 403 passes through the mounting hole 3022, and a limiting block 404 is fixed on the top of the fixed shaft 403. When the driven gear 503 is installed between the fixed shaft 403 and the mounting groove 402, the height position of the driven gear 503 is fixed between the mounting groove 402 and the limiting block 404, thereby facilitating the meshing between the driving gear 502 and the driven gear 503, and ensuring that the meshing surface of the driving gear 502 and the driven gear 503 can enable the driving gear 502 to rotate. In order to enhance the stability of the base plate 302, a limiting ring 504 is provided on the gear shaft above the teeth of the fixed gear, and the base plate 302 is rotatably installed in the limiting ring 504, and the installation distance between the floor and the fixed seat 401 is controlled by the limiting ring 504. In order to increase the stability of the base plate 302 installed in the positioning ring, a fixing block 303 can be fixedly installed at the mounting hole 3022 of the base plate 302, and the fixing block 303 is rotatably installed in the limiting ring 504. The contact area between the base plate 302 and the gear shaft of the driven gear 503 is increased by the fixing block 303, thereby enhancing the stability of the base plate 302 installed on the gear shaft. Moreover, the fixing block 303 is rotatably installed in the limiting ring 504, and will not affect the rotation of the base plate 302 relative to the fixed seat 401.

[0029] Specific implementation process:

[0030] During fan operation, the drive motor 501 rotates the drive gear 502. Since the driven gear 503 is stationary, the drive gear 502 rotates around the driven gear 503 by meshing with the teeth of the driven gear 503, thereby rotating the base 301, the bracket 201, and the fan head 101. By installing the fan's 360-degree rotating drive mechanism in the base 301, the weight of the base 301 is increased to enhance the overall stability of the fan, while avoiding the additional weight of the fan head 101 by installing the rotating drive mechanism in the fan head 101. This makes it easier to move or transport the fan during use.
