Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to an oscillating head device and a fan. Background Art

[0002] Fans are a commonly used household appliance, and most fans can shake their heads left and right to blow air to more people. However, fans are mostly used in summer and need to be stored in other seasons. In addition, traditional fans have irregular shapes and take up a large space. In related technologies, the shaking device is large in size, which is not conducive to the overall design of the product.

[0003] The Chinese invention patent with the authorization announcement number CN113090569B discloses an oscillating head device for a fan, the oscillating head device comprising: a fixing seat, the fixing seat having a through hole; a transmission shaft, the transmission shaft being rotatably mounted in the through hole; and a motor, the motor being mounted on the fixing seat, the output shaft of the motor being connected to one end of the transmission shaft, and the axis of the output shaft of the motor being colinear with the axis of the transmission shaft, the motor being used to drive the transmission shaft to rotate. The oscillating head device has the advantages of small size and high transmission efficiency; however, the oscillating head device still has structural deficiencies, and since the output shaft of the motor is directly connected to the transmission shaft, the motor load is large and the motor service life is short.

[0004] Therefore, there is still room for improvement and development in the existing technology. Utility Model Content

[0005] In order to solve the problems of the prior art, the utility model provides a shaking head device, which has a small size, high transmission efficiency and a long motor working life.

[0006] In order to achieve the above purpose, the technical solution applied by the utility model is as follows:

[0007] A shaking head device includes a column body 1, in which an inner shell can be detachably installed; a connector, which can be rotatably installed in the inner shell; a motor, which is fixedly installed in the inner shell; the output end of the motor is connected to the connector through a gear assembly, and the motor is used to drive the connector to rotate. In this arrangement, by arranging a gear assembly between the output end of the motor and the connector for transmission, the load of the motor is reduced, thereby increasing the working life of the motor; and the inner shell can be detachably installed in the column body 1, which is convenient for loading and unloading of the connector, gear assembly and motor, and convenient for maintenance. During assembly, the connector, gear assembly and motor are first assembled on the inner shell, and then the inner shell is built into the column body 1, which is convenient for loading and unloading.

[0008] According to the above solution, the gear assembly includes a large gear and a small gear. The output end of the motor is fixedly connected to the small gear. One end of the large gear is fixedly connected to the connecting head, and the other end of the large gear is meshed with the small gear. With this arrangement, when the motor operates, it drives the small gear to rotate rapidly, and the small gear then drives the large gear to rotate slowly. The large gear drives the connecting head to rotate slowly, performing a speed reduction transmission function, so that the load on the motor is small.

[0009] According to the above solution, an installation plate is formed at one end of the large gear close to the connecting head. The installation plate is fixedly connected to the connecting head by bolts, and the axis of the large gear is on the same straight line as the axis of the connecting head. With this arrangement, it is convenient to load and unload the large gear and the connecting head, and since the axis of the large gear is on the same straight line as the axis of the connecting head, the transmission efficiency is higher.

[0010] According to the above solution, a wire passing hole one is formed on the installation plate of the large gear, and a wire passing hole two is formed on the side wall of the large gear. The included angle formed between the inner walls on both sides of the wire passing hole two and the axis of the large gear is greater than 90 degrees. With this arrangement, it is more convenient for wire routing. The wire passes through the wire passing hole one and then passes out through the wire passing hole two, with little bending of the wire. Moreover, since the included angle formed between the inner walls on both sides of the wire passing hole two and the axis of the large gear is greater than 90 degrees, when the large gear rotates left and right, the wire will not touch the inner walls on both sides of the wire passing hole two, causing the wire to bend and break, thus effectively increasing the working life of the wire.

[0011] According to the above solution, an opening is formed at one end of the large gear close to the small gear. An internal gear ring is formed on the inner wall of the opening, and an external gear ring is formed on the outer wall of the small gear. The external gear ring is meshed with the internal gear ring, and the axis of the small gear is not on the same straight line as the axis of the large gear. With this arrangement, after assembly, the small gear is located inside the large gear, and the connecting head is located above the large gear in the axial direction, thereby reducing the lateral dimension of the first column, and further making the volume of the shaking device small.

[0012] According to the above solution, a bearing one and a bearing two are fixed between the outer wall of the connecting head and the inner wall of the inner housing. The bearing one and the bearing two are arranged at intervals up and down in the axial direction of the connecting head, and positioning grooves for positioning the bearing one and the bearing two are provided on the inner wall of the inner housing. With this arrangement, under the combined action of the double bearings, on the one hand, the rotation resistance of the connecting head is small and the rotation is smoother; on the other hand, it can prevent the connecting head from shaking during rotation, thereby improving the rotation stability of the connecting head.

[0013] According to the above solution, the inner housing includes a rear shell and a front shell. The rear shell and the front shell are snap-connected to form a receiving cavity for accommodating the connecting head and the motor. A power supply board is fixed on the inner wall of the rear shell, and a control board is fixed on the inner wall of the front shell. With this arrangement, it is convenient to load and unload the connecting head, the gear assembly, the motor, the double bearings, the power supply board, and the control board, and convenient for later maintenance.

[0014] A fan, comprising a fan head, a second column, a chassis and the above-mentioned swing device, wherein the connection head of the fan head and the swing device is detachably connected, one end of the second column is detachably connected to the first column of the swing device, and the other end of the second column is detachably connected to the chassis. With such a setting, the assembly is convenient. After the fan head and the connection head are assembled, the connection head can drive the fan head to swing left and right when it rotates; when the fan is not in use, it can be detachably stored, occupying a small space.

[0015] According to the above solution, there is one or more second columns, and an LED lamp board is fixed inside the second column. With such a setting, users can assemble one or more according to actual needs to form fans of different heights, which is more convenient to use; by arranging the LED lamp board inside the second column, the second column has a lighting function.

[0016] According to the above solution, after the fan head, the first column and the second column are assembled, the circuit is conducted through the cooperation of an upper coupler and a lower coupler between the fan head, the first column and the second column respectively. With such a setting, after assembly, the circuit is conducted under the cooperation of the upper coupler and the lower coupler, and after disassembly, the circuit is disconnected, which is more convenient to use.

[0017] Advantages of the present utility model:

[0018] With such a setting of the present utility model, a gear assembly is arranged between the output end of the motor and the connection head for transmission, so that the load of the motor is small, thereby improving the working life of the motor; and the inner housing can be detachably installed in the first column, which is convenient for the loading and unloading of the connection head, the gear assembly and the motor, and the maintenance is convenient.

Chassis. DETAILED DESCRIPTION

[0029] The technical solution of the utility model is described below in conjunction with the accompanying drawings and embodiments.

[0030] like Figures 1 to 6 As shown, the shaking head device of the utility model comprises a column 25, in which an inner shell 10 is detachably installed; a connector 17, in which the connector 17 is rotatably installed; a motor 22, in which the motor 22 is fixedly installed in the inner shell 10; the output end of the motor 22 is connected to the connector 17 by a gear assembly, and the motor 22 is used to drive the connector 17 to rotate. In this arrangement, by arranging a gear assembly between the output end of the motor 22 and the connector 17 for transmission, the load of the motor 22 is reduced, thereby improving the working life of the motor 22; and the inner shell 10 can be detachably installed in the column 25, which is convenient for loading and unloading of the connector 17, the gear assembly and the motor 22, and convenient for maintenance. During assembly, the connector 17, the gear assembly and the motor 22 are first assembled on the inner shell 10, and then the inner shell 10 is built into the column 25, which is convenient for loading and unloading.

[0031] Further, the gear assembly includes a large gear 20 and a small gear 21, the output end of the motor 22 is fixedly connected to the small gear 21, one end of the large gear 20 is fixedly connected to the connector 17, and the other end of the large gear 20 is meshed and connected to the small gear 21. In this arrangement, when the motor 22 is working, it drives the small gear 21 to rotate quickly, and the small gear 21 drives the large gear 20 to rotate slowly, and the large gear 20 drives the connector 17 to rotate slowly, which plays the function of speed reduction transmission, so that the load of the motor 22 is small.

[0032] Furthermore, an installation plate 6 is formed at one end of the large gear 20 close to the connector 17. The installation plate 6 is fixedly connected to the connector 17 by bolts 5, and the axes of the large gear 20 and the connector 17 are on the same straight line. This setting makes it convenient to load and unload the large gear 20 from the connector 17, and since the axes of the large gear 20 and the connector 17 are on the same straight line, the transmission efficiency is higher.

[0033] Furthermore, a wire passing hole one 31 is formed on the installation plate 6 of the large gear 20, and a wire passing hole two 32 is formed on the side wall of the large gear 20. The included angle formed between the inner walls on both sides of the wire passing hole two 32 and the axis of the large gear 20 is greater than 90 degrees. This setting makes it more convenient for wire routing. The wire passes through the wire passing hole one 31 and then passes out through the wire passing hole two 32, with small wire bending. Also, since the included angle formed between the inner walls on both sides of the wire passing hole two 32 and the axis of the large gear 20 is greater than 90 degrees, when the large gear 20 rotates left and right, the wire will not touch the inner walls on both sides of the wire passing hole two 32, resulting in wire bending and damage, thereby effectively increasing the working life of the wire.

[0034] In practical applications, by using the wire routing method with small bends between the wire passing hole one 31 and the wire passing hole two 32, it is possible to ensure small wire bending while avoiding interference between the wire and the movement space of the small gear 21.

[0035] Furthermore, an opening 7 is formed at one end of the large gear 20 close to the small gear 21. An internal gear ring 4 is formed on the inner wall of the opening 7, and an external gear ring is formed on the outer wall of the small gear 21. The external gear ring is meshed with the internal gear ring 4, and the axis of the small gear 21 is not on the same straight line as the axis of the large gear 20. With this setting, after assembly, the small gear 21 is located inside the large gear 20, and the connector 17 is located above the large gear 20 in the axial direction, thereby reducing the lateral dimension of the cylinder one 25 and making the volume of the shaking head device smaller.

[0036] Furthermore, a bearing one 18 and a bearing two 19 are fixed between the outer wall of the connector 17 and the inner wall of the inner housing 10. The bearing one 18 and the bearing two 19 are arranged at intervals in the axial direction of the connector 17, and positioning grooves for positioning the bearing one 18 and the bearing two 19 are provided on the inner wall of the inner housing 10. With this setting, under the combined action of the double bearings, on the one hand, the rotation resistance of the connector 17 is small and the rotation is smoother; on the other hand, it can prevent the connector 17 from shaking during rotation, thereby improving the rotation stability of the connector 17.

[0037] Furthermore, the inner housing 10 includes a rear shell 8 and a front shell 9. The rear shell 8 and the front shell 9 are snap-connected to form a receiving cavity for receiving the connector 17 and the motor 22. A power supply board 24 is fixed on the inner wall of the rear shell 8, and a control board 23 is fixed on the inner wall of the front shell 9. Such an arrangement facilitates the loading and unloading of the connector 17, the gear assembly, the motor 22, the double bearings, the power supply board 24, and the control board 23, and also facilitates later maintenance.

[0038] In practical applications, the shape of the inner housing 10 is the same as that of the first cylinder 25, both adopting a circular tube structure, and the outer diameter of the inner housing 10 is adapted to the inner diameter of the first cylinder 25. After assembly, the structure is more compact.

[0039] As Figure 7 and Figure 8 shown, a fan includes a fan head 101, a second cylinder 102, a chassis 103, and the above-mentioned swing device. The fan head 101 is detachably connected to the connector 17 of the swing device. One end of the second cylinder 102 is detachably connected to the first cylinder 25 of the swing device, and the other end of the second cylinder 102 is detachably connected to the chassis 103. Such an arrangement facilitates assembly. When the fan head 101 is assembled with the connector 17, the fan head 101 can be driven to swing left and right when the connector 17 rotates; when the fan is not in use, it can be detachably stored, occupying less space.

[0040] In practical applications, all parts are connected by threads, and can be quickly loaded and unloaded without tools, which is convenient for operation.

[0041] Furthermore, the second cylinder 102 is one or more, and an LED light board 30 is fixed inside the second cylinder 102. Such an arrangement allows users to assemble one or more according to actual needs to form fans of different heights, which is more convenient to use; by arranging the LED light board 30 inside the second cylinder 102, the second cylinder 102 has a lighting function.

[0042] Furthermore, after the fan head 101, the first cylinder 25, and the second cylinder 102 are assembled, the circuit is conducted between the fan head 101, the first cylinder 25, and the second cylinder 102 through the cooperation of the upper coupler 14 and the lower coupler 15 respectively. Such an arrangement enables the circuit to be conducted under the combined action of the upper coupler 14 and the lower coupler 15 after assembly, and the circuit is disconnected after disassembly, which is more convenient to use.
