Description

Technical Field

[0001] This utility model relates to the field of fan technology, specifically to a fan oscillation balancer. Background Technology

[0002] The up-and-down oscillation of a table fan is achieved through a specific mechanical structure, usually driven by a motor. Through transmission, the oscillation mechanism moves up and down reciprocally within a preset angle range. The oscillation function allows the table fan to better distribute airflow, making the air flow more evenly to all corners and increasing user comfort.

[0003] When adjusting the angle of an existing table fan, the head is prone to suddenly dropping due to a lack of stable support. For example, the connector between the fan head and the support may loosen after frequent adjustments to the fan angle or after prolonged use. A loose connector cannot provide support, and the head may drop. Utility Model Content

[0004] The purpose of this invention is to provide a fan oscillation balancer to solve the problem that existing table fans are prone to sudden drops when adjusting their up and down angles due to a lack of stable support.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fan oscillation balancer includes a connecting plate, in which a balance torsion spring is movably placed. A second slot is provided on the surface of the connecting plate for one end of the balance torsion spring to be inserted. The other end of the balance torsion spring extends beyond the outer surface of the connecting plate. A torsion spring pressure plate is detachably connected to the surface of the connecting plate and is used to limit the balance torsion spring.

[0007] Preferably, it also includes a head cover, the surface of which is provided with a connection hole for rotatable connection of the connecting disc, and the inner wall of which is provided with a first slot for the end of the balance torsion spring to be inserted.

[0008] Preferably, the headgear has two symmetrically arranged connecting holes and two symmetrically arranged first slots. The number of connecting discs, balance torsion springs, and torsion spring pressure plates are consistent with the number of connecting holes, and the two corresponding connecting discs, two balance torsion springs, and two torsion spring pressure plates are symmetrically distributed on the headgear.

[0009] Preferably, it also includes a column head, and the two connecting discs are respectively fixedly connected to the two ends of the column head.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. By setting a balancer, when the table fan oscillates up and down, the balance torsion spring will undergo elastic deformation. When the table fan swings downward, the effect of gravity will cause the head to tend to fall. At this time, the balance torsion spring will deform to generate resistance against this tendency. Its elastic restoring force will prevent the head from sinking too much, which helps to prevent the head from suddenly falling due to lack of stable support. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 4 This utility model provides a technical solution:

[0019] The fan oscillation balancer includes a connecting plate 1, a balance torsion spring 2 is movably placed inside the connecting plate 1, a second slot 8 is provided on the surface of the connecting plate 1 for one end of the balance torsion spring 2 to be inserted, the other end of the balance torsion spring 2 extends beyond the outer surface of the connecting plate 1, and a torsion spring pressure plate 3 is detachably connected to the surface of the connecting plate 1, the torsion spring pressure plate 3 is used to limit the balance torsion spring 2.

[0020] By setting a balancer, the balancer is installed at the pivot where the fan head and the support rotate. The extended part of the balance torsion spring 2 is connected to the fan head. The balance torsion spring 2 is an elastic element. When the fan is in a normal angle position, the balance torsion spring 2 is in a certain elastic deformation state. It can generate an upward supporting force on the fan head. This supporting force can balance the weight of the fan head itself. It will generate a reaction force according to the position of the head and the force.

[0021] When the table fan oscillates up and down, the extended part of the balance torsion spring 2 will move accordingly with the oscillation of the table fan, causing the balance torsion spring 2 to undergo elastic deformation. When the table fan swings downward, the effect of gravity will cause the head to tend to fall. At this time, the balance torsion spring 2 will deform to generate resistance against this tendency. Its elastic restoring force will prevent the head from sinking too much. According to Hooke's Law, the torque generated by the balance torsion spring 2 is proportional to its torsion angle. When the head begins to swing downward, the torsion angle of the balance torsion spring 2 changes, and a corresponding torque will be generated to counteract the head falling.

[0022] The balancer is specifically installed as follows: it also includes a head cover 6. The surface of the head cover 6 is provided with a connecting hole 4 for the connecting plate 1 to rotate and connect. The inner wall of the head cover 6 is provided with a first slot 5 for the end of the balance torsion spring 2 to be inserted. The head cover 6 is connected to the head of the table fan. When the head of the table fan rotates, the head cover 6 will rotate. The rotation of the head cover 6 causes the extension of the balance torsion spring 2 inserted into the first slot 5 to follow the corresponding action. Meanwhile, one end of the balance torsion spring 2 inserted into the second slot 8 remains stationary with the connecting plate 1, so that the balance torsion spring 2 undergoes elastic deformation, which generates a corresponding torque to counteract the head falling.

[0023] The headgear 6 has two symmetrically arranged connecting holes 4 and two symmetrically arranged first slots 5. The number of connecting discs 1, balance torsion springs 2, and torsion spring pressure plates 3 are consistent with the number of connecting holes 4, and the two corresponding connecting discs 1, two balance torsion springs 2, and two torsion spring pressure plates 3 are symmetrically distributed on the headgear 6.

[0024] It also includes a column head 7, with two connecting discs 1 fixedly connected to the two ends of the column head 7 respectively, so that the balancer and the column head 7 remain stationary, ensuring that the balance torsion spring 2 can generate torque when the head cover 6 rotates.

[0025] The specific steps of this solution are as follows: First, place the balance torsion spring 2 into the connecting plate 1 and embed one end of the balance torsion spring 2 into the second slot 8. Then, tighten the torsion spring pressure plate 3 and the connecting plate 1 with screws. To disassemble, simply loosen the screws. Next, install the connecting plate 1 from inside the head cover 6 into the connecting hole 4. During installation, first insert the extended part of the balance torsion spring 2 into the first slot 5. The installation method adopts a rotational connection method well known to those skilled in the art, ensuring that the connecting plate 1 and the head cover 6 can rotate relative to each other. Then, fix the column head 7 from the connecting hole 4 to the connecting plate 1. The connection method adopts a fixing method well known to those skilled in the art, ensuring that the connecting plate 1 and the column head 7 are fixed. This allows the balance torsion spring 2 to deform and generate resistance against this tendency when the table fan swings downward during the up-and-down oscillation process. Its elastic restoring force will prevent the head from sinking excessively.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
