Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and more specifically to a shaking head device. Background Art

[0002] Many air supply household appliances such as heaters or air coolers have a shaking head function to expand the air supply range and meet consumer needs.

[0003] For example, an oscillating fan can increase the area covered by the wind by shaking its head to meet the use requirements. Generally, a rotating ball is arranged outside the rotating shaft that drives the fan blades to rotate. The rotating shaft is inserted into the rotating ball. The rotating ball is movably connected to the housing of the oscillating fan. When the fan shakes its head, the rotating ball rotates relative to the housing, which can make the oscillating action more stable and extend the service life.

[0004] However, the existing oscillating mechanism for air supply equipment has some defects. Specifically, on the one hand, the existing oscillating mechanism cannot achieve 360-degree omnidirectional oscillating action, so the air supply range is greatly limited and cannot meet consumer needs. On the other hand, the existing oscillating mechanism has an unreasonable structural design, so it is unstable in operation and its life is greatly shortened.

[0005] Therefore, the industry needs to provide an improved shaking head device to overcome the above-mentioned defects of the prior art. Utility Model Content

[0006] The purpose of the utility model is to solve the above problems and provide a shaking head device.

A pair of conductive springs are arranged on the turntable; conductive electrode sheets are arranged at both axial ends of the insulating end cover; the pair of conductive springs are respectively in elastic contact with the corresponding conductive electrode sheets.

[0009] In one embodiment, each of the conductive spring sheets has a horizontal portion fixed on the rotating disk and an elastic pressing portion bent relative to the horizontal portion, and the elastic pressing portion maintains elastic contact with the corresponding conductive electrode sheet.

[0013] In one embodiment, a circuit board is disposed on the turntable bracket, and each of the conductive electrode sheets has a conductive terminal, and the conductive terminal is electrically connected to the circuit board.

[0014] In one embodiment, a motor is disposed on the support plate, a driving gear driven by the motor and a driven gear fixed in the shaft sleeve and meshing with the driving gear are disposed in the shaft sleeve.

[0016] At the same time, an air supply device is provided, comprising: the above-mentioned shaking head device and a fan assembly fixed on the turntable bracket of the shaking head device.

[0017] Compared with the prior art, the beneficial technical effects of the utility model are as follows:

[0029] In the shaking head device provided by the utility model, an insulating end cover is provided on the end of the shaft tube for preventing the turntable bracket from axially separating from the turntable, and the insulating end cover limits the turntable bracket from axially separating from the turntable during operation, thereby improving the stability of the entire shaking head device; a pair of conductive springs are arranged on the turntable; conductive electrode sheets are provided at both axial ends of the insulating end cover; a pair of conductive springs respectively maintain elastic contact with the corresponding conductive electrode sheets, so when the turntable bracket rotates relative to the turntable, no matter to which angle it rotates, the conductive electrode sheets and the corresponding conductive spring sheets maintain electrical contact, ensuring electrical connection at any time, thereby realizing a 360-degree shaking head function.

[0030] In one embodiment of the present invention, reference Figure 1-5 , a shaking head device 100 is provided, which can be integrated into other air supply household appliances, such as heaters, air coolers, humidifiers and other equipment, so as to realize the shaking head function of the equipment, such as a 360-degree shaking head function, thereby expanding the air supply angle and range of the household appliances. Of course, the shaking head device of the utility model can also be used in industrial equipment to achieve a similar shaking head effect.

[0031] The oscillating device 100 comprises: a turntable 10 having a sleeve 14 and a turntable support 20 having a shaft cylinder 24, wherein the shaft cylinder 24 extends into the sleeve 14 and rotates relative to the sleeve 14, and an insulating end cover 30 is provided at the end of the shaft cylinder 24 for preventing the turntable support 20 from axially separating from the turntable 10. A pair of conductive springs 48 are provided on the turntable 10; conductive electrode sheets 44 are provided at both axial ends of the insulating end cover 30; and the pair of conductive springs 48 are respectively in elastic contact with the corresponding conductive electrode sheets 44.

[0032] In one embodiment, the insulating end cap 30 is made of a suitable insulating material, such as plastic, to enhance the insulation effect and ensure the high insulation degree of the electrical equipment. In this embodiment, the insulating end cap 30 not only plays an insulating role, but also prevents the turntable bracket 20 from axially disengaging from the turntable 10 during operation.

[0033] In addition, the conductive spring 48 can be formed of a conductive material with good conductive properties. In one embodiment, it can be made of copper. The copper material not only has good conductive properties, but also has certain anti-oxidation properties, ensuring that the conductive properties are not affected by the external environment. At the same time, metal copper has a certain elasticity, so it can ensure that the conductive spring 48 continues to reliably maintain dynamic contact with the corresponding conductive electrode sheet 44, thereby ensuring a stable electrical connection.

[0034] Similarly, the conductive electrode sheet 44 can also be made of copper. The copper material not only has good electrical conductivity, but also has certain anti-oxidation properties, ensuring that the electrical conductivity is not affected by the external environment. In addition, the metal copper has elasticity, so it can ensure continuous and reliable contact with the corresponding conductive spring sheet 48, thereby ensuring a stable electrical connection between the two, and ultimately ensuring that the corresponding shaking motor can always drive the shaking device to achieve a 360-degree shaking function.

[0035] In addition, the conductive electrode sheet 44 has a good structural reinforcement effect on the insulating end cover 30, ensuring the structural stability of the insulating end cover 30, and the conductive electrode sheet 44 made of metal is more wear-resistant and has a better life when rubbing against the turntable 20. At the same time, the two conductive electrode sheets 44 are welded with wire harnesses, which lead from the hollow part of the turntable 10 to the circuit board above the turntable bracket 20.

[0036] Preferably, each of the conductive spring sheets 48 has a horizontal portion 482 fixed on the turntable 10 and a spring-pressing portion 484 bent relative to the horizontal portion 482, and the spring-pressing portion 484 maintains elastic contact with the corresponding conductive electrode sheet 44. This structural setting can, on the one hand, fix the conductive spring sheet 48 on the turntable 10, and on the other hand, allow the entire conductive spring sheet 48 to have a certain degree of elasticity.

[0037] In one embodiment, the turntable 10 has a bottom plate 12, a through hole is provided in the center of the bottom plate 12, and the shaft sleeve 14 is extended along the axial direction. Here, the bottom plate 12 and the shaft sleeve 14 are integrally formed, so that the strength of the entire turntable 10 is sufficiently stable, ensuring that the shaking device 100 has a long service life. In other embodiments, in order to facilitate disassembly and maintenance, the bottom plate 12 and the shaft sleeve 14 can also be designed as separate components, and fixed together by means of, for example, snaps or threads.

[0038] Preferably, the turntable bracket 20 has a support plate 22, a through hole is provided in the center of the support plate 22, and the shaft cylinder 24 is extended along the axial direction. The shaft cylinder 24 is used as a rotating shaft to rotate with the turntable 10. The shaft cylinder 24 is hollow inside, and various wires of the oscillating device 100 can pass through to realize the electrical connection between various components.

[0039] Regarding the fixing method of the conductive spring sheet, in one embodiment, the two horizontal portions 482 are fixed to the bottom surface of the bottom plate 12 at intervals through an insulating block 41. Here, the insulating block 41 is used to achieve electrical insulation between the corresponding two horizontal portions 482.

[0040] Preferably, the pair of conductive springs 48 are electrically connected to the socket 16 provided on the turntable 10. In this way, when the external power source is connected to the socket 16, the external power source supplies power to the conductive springs 48 through the socket 16, and accordingly, the conductive electrode sheet 44 in dynamic electrical contact with the conductive springs 48 is also supplied with power at the same time, thereby being able to continuously supply power to the corresponding drive motor, ensuring the continuous operation of the drive motor, and finally achieving a 360-degree shaking effect.

[0041] In one embodiment, a circuit board 26 is disposed on the turntable bracket 20, and each of the conductive electrode sheets 44 has a conductive terminal 442, and the conductive terminal 442 is electrically connected to the circuit board 26. In this way, the circuit board 26 is electrically connected to the conductive electrode sheets 44. The utility model has no limitation on the position of the circuit board 26. In other embodiments, the circuit board 26 can also be disposed on other components of the oscillating device, as long as it does not affect the electrical connection between it and the corresponding conductive electrode sheets 44.

[0042] Preferably, the support plate 22 is provided with a motor 28, the shaft sleeve 14 is provided with a driving gear 21 driven by the motor 28, and a driven gear 16 fixed in the shaft sleeve 14 and meshing with the driving gear 21. Through the transmission action of the motor 28 and the corresponding transmission device (two gears that cooperate with each other), the rotational power generated by the motor 28 can be transmitted to the turntable bracket 20, thereby realizing the shaking function. The motor 28 can be any appropriate motor, such as a DC motor or an AC motor, and the utility model does not limit this.

[0043] The above-mentioned shaking head device 100 also includes a bottom cover 50 that is buckled on the bottom of the turntable 10. The bottom cover 50 covers the various components installed on the bottom surface of the turntable 10 on the one hand, which plays a role in aesthetics, and on the other hand, it plays a role in dust protection for the various components. The bottom cover 50 can be fixed to the turntable 10 with the help of screws, or threads can be directly set on the bottom cover 50, and corresponding threads can be set at the corresponding positions of the turntable 10 to achieve spiral fixation between the two. Of course, a snap-fit ​​structure can also be set on the bottom cover 50 and the turntable 10 to achieve convenient installation and fixation between the two by snapping.

[0044] The utility model further provides an air supply device 200 , comprising: the oscillating device 100 described in the above-mentioned embodiments and a fan assembly 202 fixed on a turntable bracket of the oscillating device 100 .

[0045] Since the shaking head device 100 can achieve a 360-degree shaking head movement without dead angles, the corresponding air supply device 200, such as a heater or a cooler, can also achieve the same effect. This expands the air supply angle range of the air supply device and can supply air to the indoor space in the entire range, thereby meeting user needs.

[0047] The above description is only a partial implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
