Description

Technical Field

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

[0002] The existing electric heater shaking mechanism usually realizes shaking direction reversing through a crank connecting rod mechanism or a gear rack mechanism.

[0003] If a rack and pinion mechanism is used, a synchronous motor drives the rack and pinion to force the machine to shake its head and change direction. Because the rack and pinion mesh with each other, their assembly clearance is small, the machine shakes smoothly, and the machine body shakes little. However, this rack and pinion mechanism needs to stop moving first and then move in the opposite direction when changing direction, which will cause the whole machine to shake and affect user use.

[0004] If a crank-connecting rod mechanism is used, the crank of the crank-connecting rod mechanism is always making circular motion in the same direction, and there is no problem of forced reversing jitter of the gear rack. In order to ensure smooth and stable shaking of the machine, the crank-connecting rod mechanism connecting the fuselage and the base needs to be designed with clearance fit, and in order to avoid deformation of parts and insufficient assembly clearance, which leads to shaking of the machine, it is necessary to increase the assembly clearance so that the whole machine can shake smoothly. However, this will bring new problems, that is, when the user operates the function buttons of the whole machine, a force will be applied to the fuselage, and there is a gap between the fuselage and the base, which will cause the whole machine to shake, which will also affect the user's use. Summary of the invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the shaking mechanism in the prior art that either jitter occurs during switching or the whole machine shakes when operating the function keys, thereby providing a shaking mechanism and a device with a shaking mechanism that can avoid jitter during switching and prevent the whole machine from shaking when operating the function keys.

[0006] The present invention provides a shaking head mechanism, comprising:

[0007] A power device having a power output end for outputting rotational power;

[0008] A crank-connecting rod mechanism, comprising a crank and a connecting rod, wherein one end of the crank is fixedly connected to the power output end, and one end of the connecting rod is hinged to the other end of the crank;

[0010] A first structure is fixedly connected to the power device;

[0011] A second structure is fixedly connected to the rotating structure;

[0012] The rolling structure is disposed between the first constituent structure and the rotating structure, and is in rolling contact with at least one of the first constituent structure and the rotating structure.

[0013] The rotating structure comprises:

[0014] A turntable, which is ring-shaped and fixedly connected to the second structure;

[0015] The rocker is linked with the rotating disk, and one end of the rocker is rotatably mounted on the first structure, and the other end is hinged to the other end of the connecting rod.

[0016] The first constituent structure comprises:

[0020] The rolling structure comprises:

[0021] The ball support comprises a ring-shaped frame body and a plurality of ball mounting holes distributed on the frame body at intervals along the circumference of the frame body;

[0022] A plurality of balls are arranged on the corresponding ball mounting holes and are in rolling contact with at least one of the mounting frame and the rotating disk.

[0023] The frame body is detachably connected to the turntable.

[0024] At least one clamping block is arranged on the outer peripheral wall of the frame body, and at least one clamping groove suitable for accommodating the clamping block is arranged on the rotating disk.

[0025] At least two clamping blocks are arranged on the outer peripheral wall of the frame body and are distributed at intervals along the circumference of the frame body; at least two clamping grooves are arranged on the turntable, and the clamping grooves are arranged in a one-to-one correspondence with the clamping blocks.

[0026] The rolling structure also includes a plurality of limiting structures, which are arranged one-to-one corresponding to the ball mounting holes and include two limiting blocks relatively arranged on the outside of the ball mounting holes, the distance between the two limiting blocks is smaller than the diameter of the ball, and an opening suitable for the ball to extend out is formed between the two limiting blocks.

[0027] An annular sliding groove suitable for accommodating the ball is provided on the outer peripheral wall of the mounting frame.

[0028] The power device is a motor, the power output end is an output shaft of the motor, and the mounting frame is a motor bracket.

[0029] The second constituent structure is a base.

[0030] The present invention also provides a device with an oscillating mechanism, comprising the oscillating mechanism mentioned above.

Since the first constituent structure is fixedly connected to the power device, and the second constituent structure is fixedly connected to the rotating structure, when one of the first constituent structure and the second constituent structure is fixed, the crank can be driven by the power device to rotate in a circle, thereby driving the connecting rod to move, so that the connecting rod and the rotating structure rotate relative to each other, thereby realizing relative rotation between the first constituent structure and the second constituent structure, that is, realizing "shaking head"; at the same time, since the power device is a crank-connecting rod mechanism movement, that is, the power of the power device is transmitted to the rotating structure by the circular motion of the crank, there is no need to stop after moving to a certain position and then move in the opposite direction to achieve reversal, so there will be no shaking between the first constituent structure and the second constituent structure; in addition, since a rolling structure is provided between the first constituent structure and the rotating structure, the rolling structure is in rolling contact with at least one of the first constituent structure and the rotating structure, so that when the first constituent structure and the second constituent structure rotate relative to each other, the sliding contact between the first constituent structure and the rotating structure changes to rolling contact, which has the characteristics of small radial clearance and small jump, thereby realizing stable shaking of the whole machine and no shaking of the fuselage, thereby improving the performance of the whole machine.

The oscillating mechanism provided by the present invention, the rolling structure includes: a ball support, including a ring-shaped frame body, and a plurality of ball mounting holes on the frame body that are spaced apart along the circumference of the frame body; a plurality of balls, which are arranged on the corresponding ball mounting holes and are in rolling contact with at least one of the mounting frame and the turntable. This type of rolling structure is not only simple in structure and easy to implement, but also the circumferential spacing of the plurality of ball frame bodies can make the rolling contact between the balls and the mounting frame or the turntable more stable.

[0047] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0049] like Figure 1-Figure 8 As shown, this embodiment provides a shaking head mechanism, including a power device, a crank-connecting rod mechanism, a rotating structure, a first constituent structure, a second constituent structure and a rolling structure.

[0050] The power device has a power output end for outputting rotational power.

[0051] The crank-connecting rod mechanism comprises a crank 21 and a connecting rod 22 . One end of the crank 21 is fixedly connected to the power output end, and one end of the connecting rod 22 is hinged to the other end of the crank 21 .

[0052] The rotating structure is rotatably connected to the other end of the connecting rod 22 .

[0053] The first constituent structure is fixedly connected to the power device.

[0054] The second constituent structure is fixedly connected to the rotating structure.

[0055] The rolling structure is disposed between the first constituent structure and the rotating structure, and is in rolling contact with at least one of the first constituent structure and the rotating structure.

[0056] Since the first constituent structure is fixedly connected to the power device, and the second constituent structure is fixedly connected to the rotating structure, when one of the first constituent structure and the second constituent structure is fixed, the crank 21 can be driven by the power device to rotate in a circle, thereby driving the connecting rod 22 to move, so that the connecting rod 22 and the rotating structure rotate relative to each other, thereby realizing relative rotation between the first constituent structure and the second constituent structure, that is, realizing "shaking head"; at the same time, since the power device is a crank-connecting rod mechanism movement, that is, the power of the power device is transmitted to the rotating structure by the circular motion of the crank 21, there is no need to stop after moving to a certain position and then move in the opposite direction to achieve reversal, so there will be no shaking between the first constituent structure and the second constituent structure; in addition, since a rolling structure is provided between the first constituent structure and the rotating structure, the rolling structure is in rolling contact with at least one of the first constituent structure and the rotating structure, so that when the first constituent structure and the second constituent structure rotate relative to each other, the sliding contact between the first constituent structure and the rotating structure changes to rolling contact, which has the characteristics of small radial clearance and small jump, thereby realizing stable shaking of the whole machine and no shaking of the fuselage, thereby improving the performance of the whole machine.

[0057] In this embodiment, the rotating structure includes a turntable 31 and a rocker 32 .

[0058] The turntable 31 is ring-shaped and fixedly connected to the second structure.

[0059] The rocker 32 is linked to the turntable 31, and one end of the rocker 32 is rotatably mounted on the first structure, and the other end is hinged to the other end of the connecting rod 22. There are many specific ways to realize the linkage connection between the rocker 32 and the turntable 31. In this embodiment, the rocker 32 and the turntable 31 are linked to each other by keyway cooperation.

[0060] The specific structural forms of the first structure can be various. In this embodiment, the first structure includes a housing 41 , a mounting frame 42 and a support base 43 .

[0061] The mounting frame 42 is fixedly connected to the casing 41 and the power device respectively.

[0062] The support base 43 is fixedly mounted on the housing 41 and is provided with a support shaft 431 extending toward the second structure. The rocker 32 is sleeved on the support shaft 431 .

[0063] The mounting frame 42 and the supporting seat 43 in this embodiment are detachably connected. As a convertible implementation, the mounting frame 42 and the supporting seat 43 can also be integrally formed.

[0064] The rolling structure may have various specific structural forms. In this embodiment, the rolling structure includes a ball support and a plurality of balls 52 .

[0066] The plurality of balls 52 are disposed on the corresponding ball mounting holes 512 and are in rolling contact with the mounting frame 42 .

[0067] This type of rolling structure is not only simple in structure and easy to implement, but also the circumferential spacing of the plurality of ball bearings 52 on the frame body 511 can make the rolling contact between the ball bearings 52 and the mounting frame 42 or the turntable 31 smoother.

[0068] As a convertible embodiment, the frame body 511 may be mounted on the mounting frame 42 , and the balls 52 may be in rolling contact with the turntable 31 .

[0069] In this embodiment, the frame body 511 is detachably connected to the turntable 31. As a convertible implementation, the frame body 511 can also be integrally formed with the turntable 31.

[0070] There are many specific ways to realize the detachable connection between the frame body 511 and the turntable 31. In the embodiment, at least one block 61 is provided on the outer peripheral wall of the frame body 511, and at least one slot 62 suitable for accommodating the block 61 is provided on the turntable 31. In this way, the detachable connection between the ball bracket and the turntable 31 can be realized by inserting the block 61 into the slot 62 or taking it out from the slot 62, which has the advantages of simple structure and convenient disassembly and assembly. At the same time, the ball bracket can also be limited in the circumferential direction to prevent the relative rotation between the ball bracket and the turntable 31. As a convertible embodiment, the frame body 511 and the turntable 31 can also be connected by screws.

[0071] The specific number of the blocks 61 and the slots 62 is not limited. In this embodiment, two blocks 61 are provided on the outer peripheral wall of the frame body 511 and are spaced apart along the circumference of the frame body 511; two slots 62 are provided on the turntable 31, and the slots 62 are arranged one-to-one with the blocks 61. As a convertible implementation, only one block 61 may be provided on the frame body 511 and only one slot 62 may be provided on the turntable 31; or three blocks 61 may be provided on the frame body 511 and three slots 62 may be provided on the turntable 31.

[0072] In order to effectively prevent the ball 52 from escaping from the ball mounting hole 512, the rolling structure in this embodiment also includes a plurality of limiting structures, which are arranged one-to-one corresponding to the ball mounting holes 512, and include two limiting blocks 71 relatively arranged on the outside of the ball mounting holes 512, the distance between the two limiting blocks 71 is smaller than the diameter of the ball 52, and an opening 72 suitable for the ball 52 to extend out is formed between the two limiting blocks 71.

[0073] In order to make the rolling of the balls 52 more stable, an annular groove 8 suitable for accommodating the balls 52 is respectively provided on the outer peripheral wall of the mounting frame 42 and the inner peripheral wall of the turntable 31 , and each ball 52 rolls in the annular groove 8 .

[0074] The specific structural form of the power device is not limited. In this embodiment, the power device is a motor 1, the power output end is the output shaft of the motor 1, and the mounting frame 42 is a motor bracket.

[0075] The second structure in this embodiment is the base 9. As a convertible implementation, the base 9 can also be replaced by other structures.

[0076] This embodiment also provides an electric heater, including the above-mentioned oscillating mechanism. As a convertible implementation, the electric heater can also be replaced by other devices with oscillating mechanisms.

[0077] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
