Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, if the term "plurality" appears, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0055] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connected," "fixed," etc., should be interpreted broadly. For example, these terms may refer to fixed connections, removable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; and internal communication between two components or interaction between two components, unless otherwise specified.

When a first feature is described as being "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0057] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only embodiment.

[0058] See Figure 1 A household appliance provided in one embodiment of the present application includes a base 40 and an oscillating mechanism disposed on the base 40. The oscillating mechanism includes a body member 10, a flexible member 20, and a head assembly 30. The body member 10 is disposed on the base 40 to support the head assembly 30. The flexible member 20 is movably mounted on the body member 10 along a first direction X. The head assembly 30 includes a hinge portion 31 and a fixed portion 32. The hinge portion 31 and the fixed portion 32 are arranged at intervals along a second direction Y. The hinge portion 31 is hinged to the body member 10 about a hinge axis, and the fixed portion 32 is connected to the flexible member 20.

[0059] The flexible part 20 refers to a part made of a material that can produce a certain deformation under the action of an external force. The material includes but is not limited to rubber, silicone, latex, or metal with good ductility.

[0060] When the flexible member 20 moves along the first direction X, the flexible member 20 drives the fixed portion 32 to move along the first direction X, thereby driving the head assembly 30 to rotate about the hinge axis, thereby achieving the swinging of the head assembly 30 relative to the body 10. In addition, due to the inherently deformable nature of the flexible member 20, when the head assembly 30 rotates relative to the body 10, the flexible member 20 will automatically stretch or compress according to the position of the head assembly 30 to adapt to the position change of the lens assembly.

[0061] Specifically, see Figure 2, the first direction X is the direction of gravity, the second direction Y is the horizontal direction, and the third direction is the direction perpendicular to the paper. Figure 2 In the embodiment, the hinged portion 31 and the fixed portion 32 are on the same horizontal line. At this time, the hinged portion 31 and the fixed portion 32 share the weight of the head assembly 30 together.

[0062] When the flexible member 20 moves upward relative to the hinge portion 31, as shown in FIG. Figure 3 As shown, the flexible member 20 pushes the handpiece assembly 30 to rotate counterclockwise around the hinge axis, achieving an upward head swing. At this point, the center of the handpiece assembly 30 gradually deviates toward the hinge portion 31, and under the influence of gravity, the handpiece assembly 30 tends to continue moving counterclockwise. To this end, the flexible member 20 stretches, using its own elastic force to balance the weight of the handpiece assembly 30.

[0063] And in Figure 2 On the basis of, when the flexible member 20 moves downward relative to the hinge portion 31, as Figure 4 As shown, the flexible member 20 pushes the handpiece assembly 30 to rotate counterclockwise around the hinge axis, causing the handpiece assembly 30 to tilt downward. At this point, the center of the handpiece assembly 30 gradually shifts toward the flexible member 20, increasing the pressure on the flexible member 20. To this end, the flexible member 20 is compressed to accommodate the pressure applied by the handpiece assembly 30.

[0064] In this way, the movable flexible member 20 not only drives the head assembly 30 to swing about the hinge axis, thereby achieving the swing of the head assembly 30 relative to the body member 10, but also adapts to the position change of the head assembly 30 through the deformation of the flexible member 20 itself, so that during the swinging process of the head assembly 30, the flexible member 20 can form a stable connection with the head assembly 30, ensuring the stability of the swinging of the head assembly 30. Compared with the traditional swinging mechanism, the above-mentioned swinging mechanism can achieve the swinging of the head assembly 30 by only using a movable flexible member 20, without the need for a complex transmission mechanism, thereby improving space utilization and streamlining the volume of the head assembly 30.

[0065] Optionally, the household appliance is a fan or a circulating fan, and the head assembly 30 is provided with rotatable blades to form airflow through the rotation of the blades. The head assembly 30 can swing in the first direction X through the flexible member 20, thereby allowing the airflow blown by the head assembly 30 to cover a larger space, thereby improving the user experience.

[0066] In other embodiments, the household appliance may be a heater. In this case, the head assembly 30 may be a component that outputs radiant heat. The head assembly 30 may swing through the flexible member 20 so that the radiant heat can cover a wider area, thereby improving the user experience. In still other embodiments, the household appliance may be a humidifier or air purifier that requires oscillation.

[0067] In some embodiments of this application, see Figure 4 The fixing portion 32 is detachably connected to the flexible member 20, that is, the head assembly 30 can be separated from the flexible member 20. In actual use, by separating the head assembly 30 from the flexible member 20, the head assembly 30 can be rotated around the hinge axis at a greater angle, so that the angle of the head assembly 30 is more flexible.

[0068] Specifically, see Figure 5 、 Figure 6 and Figure 7 By separating the head assembly 30 from the flexible part 20, the head assembly 30 can rotate to a larger angle, and when the head assembly 30 rotates counterclockwise until it abuts against the body part 10, the head assembly 30 will stop rotating under the action of the body assembly, thereby maintaining the current position, and at this time the height of the head assembly 30 is lower to meet the user's needs for low-angle blowing and other uses.

[0069] In some embodiments, the interior of the body member 10 further defines an accessory cavity 11, and the household appliance further comprises a working accessory 41, which is disposed within the accessory cavity 11 and is used to cooperate with the handpiece assembly 30 to achieve a better working effect. Optionally, the household appliance is a cooling fan, and the working accessory 41 is a water tank 42, which is connected to the handpiece assembly 30 so that water in the water tank 42 can be input into the handpiece assembly 30 and atomized to form water vapor within the handpiece assembly 30. Finally, the water vapor, together with the airflow generated by the random head assembly 30, acts on the human body, thereby achieving a more significant cooling effect on the human body surface.

[0070] It is understandable that when the household appliance is a humidifier, the working accessory 41 can also be a fragrance component, or when the household appliance is an air purifier, the working accessory 41 can be a filter element, etc. The working accessory 41 can be selected according to the type of household appliance and is not limited here.

[0071] Furthermore, the flexible member 20 defines a clearance hole 21, which communicates with the accessory cavity 11. When the fixing portion 32 is connected to the flexible member 20, the handpiece assembly 30 closes the clearance hole 21. Specifically, when the fixing portion 32 is connected to the flexible member 20, the handpiece assembly 30 covers the end of the clearance hole 21, thereby keeping the clearance hole 21 closed. When the clearance hole 21 is closed, the working accessory 41 is retained within the accessory cavity 11 and is unlikely to escape from the clearance hole 21. This ensures the stability of the working accessory 41 during normal operation of the household appliance, allowing the handpiece assembly 30 to function properly.

[0072] When the fixing portion 32 is separated from the flexible portion 20, the head assembly 30 can open the avoidance hole 21 during the movement of the head assembly 30 relative to the body portion 10, and when the head assembly 30 opens the avoidance hole 21, the working accessory 41 can enter or leave the accessory cavity 11 through the avoidance hole 21, so that the user can place the working accessory 41 into the accessory cavity 11, or pull the working accessory 41 out of the accessory cavity 11.

[0073] Specifically, when the household appliance is a fan and the working accessory 41 is a water tank 42, when the user needs to refill the water tank 42 with water, the user can separate the flexible part 20 and the fixed part 32 from each other, and rotate the head assembly 30 so that the avoidance hole 21 is opened. At this time, the user can take the water tank 42 out of the accessory cavity 11 through the avoidance hole 21, so that the user can perform the water refilling operation on the water tank 42 alone.

[0074] After the user has finished refilling the water tank 42, the user can align the water tank 42 with the avoidance hole 21 to return the water tank 42 to the accessory cavity 11. The head assembly 30 can then be rotated to a position where the flexible member 20 and the fixing portion 32 can be fixed to each other. After the flexible member 20 and the fixing portion 32 are fixed to each other, the head assembly 30 can function normally. Optionally, a handle 43 is provided on the top of the water tank 42 to facilitate the user to take the water tank 42.

[0075] Furthermore, a limit member 15 is provided on the body member 10. The limit member 15 is located in the accessory cavity 11. When the working accessory 41 enters the accessory cavity 11, it can abut against the limit member 15. The limit member 15 prevents the working accessory 41 from continuing to move, thereby allowing the working accessory 41 to be fixed in the position abutting against the limit member 15. That is, the limit member 15 allows the working accessory 41 to be installed in place. Moreover, when the user finds that the working accessory 41 cannot continue to move during installation, it can be understood that the working accessory 41 has been installed in place. At this time, the user can rotate the head assembly 30 to close the avoidance hole 21 and connect the flexible member 20 to the fixing portion 32. After that, the household appliance can be used normally.

[0076] In some embodiments of this application, see Figure 8 To connect and disconnect the fixed portion 32 from the flexible member 20, a fixing hole 33 is provided on the fixed portion 32, and a support hole 22 is provided on the flexible member 20. During movement of the head assembly 30 about the hinge axis, the fixing hole 33 and the support hole 22 align with each other, and both extend longitudinally along the hinge axis. The oscillation mechanism also includes a latch 50, which can be inserted into both the fixing hole 33 and the support hole 22 when the fixing hole 33 and the support hole 22 are aligned.

[0077] Thus, when the latch 50 is inserted into the fixing hole 33 and the support hole 22, the latch 50 restricts the fixing portion 32 from rotating relative to the flexible member 20, thereby securing the head assembly 30 to the flexible member 20 and the body 10. When the latch 50 is separated from at least one of the fixing hole 33 and the support hole 22, the latch 50 no longer restricts the fixing portion 32 from rotating relative to the flexible member 20, and the rotation of the head assembly 30 can now be controlled.

[0078] Specifically in some embodiments, the pin 50 can be telescopically arranged in the fixing hole 33, and the shaking mechanism also includes an elastic member 51, which is arranged between the fixing part 32 and the pin 50. The pin 50 has an extended end 52 that can extend out of the fixing hole 33 and insert into the support hole 22. During the process of retracting the extended end 52 relative to the fixing hole 33, the elastic member 51 accumulates an elastic force for extending the extended end 52.

[0079] In this way, the elastic member 51 ensures that the latch 50 will only separate from the support hole 22 when an external force sufficient to overcome the elastic member 51 is applied. Therefore, even when the household appliance is being transported, the latch 50 will not easily separate from the support hole 22, thereby ensuring the reliability of the connection between the fixing portion 32 and the flexible member 20. Furthermore, because the latch 50 is fixed to the fixing member, even after the user controls the fixing portion 32 to separate from the flexible member 20, the latch 50 will remain on the fixing portion 32. Compared to a method in which the latch 50 is separated from both the support hole 22 and the fixing hole 33, the latch 50 is less likely to be lost and is more convenient for the user to operate.

[0080] Furthermore, to facilitate user operation, the latch 50 includes an operating end 53. The operating end 53 and the extending end 52 are disposed opposite each other at opposite ends of the latch 50, and the operating end 53 extends out of the fixing hole 33. This allows the user to grasp the operating end 53 and pull the latch 50, causing the extending end 52 to retract into the fixing hole 33, thereby separating the latch 50 from the support hole 22 and the fixing portion 32 from the flexible member 20. When the user releases the operating end 53, the latch 50, under the action of the elastic member 51, causes the extending end 52 to extend and then be inserted into the supporting hole 22, completing the connection between the fixing portion 32 and the flexible portion.

[0081] Optionally, the elastic member 51 is a spring, which is sleeved over the latch 50. A limiting protrusion 54 is provided on the latch 50, with the ends of the spring respectively abutting against the limiting protrusion 54 and the bottom wall of the fixing hole 33. Furthermore, a spring stopper 17 is provided on the fixing portion 32, and the spring stopper 17 has a stopper hole. The latch 50 is inserted into the stopper hole, and the diameter of the stopper hole is smaller than the limiting protrusion 54. The spring stopper 17 prevents the latch 50 from falling out of the fixing hole 33.

[0082] In some other embodiments, the latch 50 can also be set on the flexible part 20, that is, the latch 50 can be retractably arranged in the support hole 22, and the elastic part 51 is arranged between the flexible part 20 and the latch 50. The latch 50 has an extended end 52 that can extend out of the support hole 22 and insert into the fixing hole 33, and an operating end 53 that extends out of the support hole 22. During the process of retracting the extended end 52 relative to the support hole 22, the elastic part 51 accumulates an elastic force for extending the extended end 52.

[0083] In some embodiments of the present application, the oscillating mechanism further includes a driving member 60 for providing power to the movement of the flexible member 20. Since the flexible member 20 only has one movement in the first direction X, the driving member 60 can be a structure capable of outputting linear motion, such as a linear module, a gear rack, or a cylinder.

[0084] In actual use, if the user is dissatisfied with the angle of the handpiece assembly 30, they may violently twist the handpiece assembly 30. To prevent the driver 60 from being damaged by violent shaking, in some embodiments, the driver 60 is a hydraulic cylinder having a piston rod 62 that moves along the first direction X. The piston rod 62 is connected to the flexible member 20, thereby driving the flexible member 20 to move along the first direction X via the hydraulic cylinder.

[0085] Because the hydraulic cylinder has a strong load-bearing capacity and good durability, it can also resist damage when the user shakes his head violently. At the same time, after long-term use, the hydraulic mechanism can maintain sufficient stability and is not prone to failure, which effectively improves the service life and reliability of household appliances.

[0086] For specific embodiments, see Figure 9 、 Figure 10 and Figure 11 The oscillating mechanism further includes a lifting support member 61, which is movably mounted on the body member 10 along the first direction X. The lifting support member 61 is connected to the driving member 60, and the flexible member 20 is disposed on the lifting support member 61. The driving member 60 drives the lifting support member 61 to move the flexible member 20 along the first direction X, thereby pushing the head assembly 30 to oscillate.

[0087] In actual use, the head assembly 30 is located at the top of the body 10 and is a long distance away from the drive member 60. Therefore, placing the flexible member 20 on the lifting support member 61 can reduce the length of the flexible member 20 and reduce production costs. Optionally, a mounting groove is formed at the bottom of the flexible member 20, and the top of the lifting support member 61 is inserted into the mounting groove to mount the flexible member 20 on the lifting support member 61.

[0088] Furthermore, a mounting hole 16 is defined on the top of the fuselage member 10. The mounting hole 16 communicates with the accessory cavity 11 within the fuselage member 10. The lifting support member 61 is disposed through the mounting hole 16 and extends out of the mounting hole 16. The flexible member 20 is mounted on the portion of the lifting support member 61 extending out of the mounting hole 16. A connecting hole 64 is defined within the lifting support member 61, extending along the first direction X. One end of the connecting hole 64 communicates with the avoidance hole 21 in the flexible member 20, and the other end communicates with the accessory cavity 11. The working accessory 41 can sequentially pass through the avoidance hole 21 and the connecting hole 64 to enter the accessory cavity 11, or exit the accessory cavity 11 through the connecting hole 64 and the avoidance hole 21.

[0089] Furthermore, in order to facilitate driving the lifting support member 61, the driving member 60 is also arranged in the accessory cavity 11. In this way, the lifting support member 61 and the driving member 60 are both arranged inside the fuselage member 10, which can make the overall lifting mechanism more compact and the space utilization rate higher.

[0090] In some embodiments, since both the lifting support member 61 and the flexible member 20 are disposed at the top of the body member 10, the flexible member 20 may easily cause the head assembly 30 to collide with the top of the body member 10 when driving the head assembly 30 downward. Therefore, to prevent the body member 10 from interfering with the rotation of the head assembly 30, in some embodiments, the body member 10 includes a first end 12 and a second end 13 opposite to each other in the first direction X, the second end 13 being disposed on the base 40, the first end 12 being hinged to the hinge portion 31, and the distance between the first end 12 and the second end 13 gradually decreasing in the second direction Y and in the direction away from the hinge portion 31.

[0091] That is, in the second direction Y and in the direction away from the hinge part 31, the height of the fuselage part 10 gradually decreases, and the direction in which the height of the fuselage part 10 decreases is exactly the direction in which the head assembly 30 swings downward. The lowered height of the fuselage part 10 can just be used to accommodate the head assembly 30 that swings downward, thereby avoiding the fuselage part 10 interfering with the movement of the head assembly 30.

[0092] In one embodiment, the fuselage member 10 has an oblique cutout 14 at the first end 12. The oblique cutout 14 has a highest point and a lowest point in the first direction X. The highest point and the lowest point are spaced apart along the second direction Y, and the lowest point is located on the side of the highest point away from the hinge portion 31. In this way, the height of the fuselage member 10 gradually decreases at the oblique cutout 14, freeing up space for the downward swing movement of the head assembly 30.

[0093] Furthermore, the outer shell of the head assembly 30 is cylindrical, and during the movement of the head assembly 30 with the flexible member 20, the outer shell of the head assembly 30 may contact the edge of the bevel cut 14 of the body member 10. In order to ensure smoother contact between the head assembly 30 and the edge of the bevel cut 14, the projection of the edge of the bevel cut 14 on a plane is an arc, and the plane is perpendicular to the hinge axis. That is, the surface of the body member 10 at the cut of the bevel cut 14 is an arc, and the outer shell surface of the head assembly 30 is also an arc. The contact between the arcs can make the head assembly 30 more compatible with the end of the body member 10, avoiding damage to the head assembly 30 or the body member 10.

[0094] In some embodiments, the shaking head assembly includes multiple hydraulic connecting rods 63, each hydraulic connecting rod 63 is connected to the piston rod 62 of the hydraulic cylinder, and the other end is connected to the lifting support 61, so that the driving force of the piston rod 62 is shared by multiple hydraulic connecting rods 63, so that the driving force of the piston rod 62 can be dispersed to various parts of the lifting support 61, so that the lifting support 61 as a whole can rise smoothly.

[0095] Specifically, the piston rod 62 is located inside the connection hole 64 of the lifting support member 61, and the hydraulic connecting rods 63 include two. The inner wall of the connection hole 64 is provided with two connecting rod holes. One end of the two hydraulic connecting rods 63 is connected to the piston rod 62, and the other end is inserted into the connecting rod holes, so that the lifting support member 61 can be lifted simultaneously by the two hydraulic connecting rods 63. Optionally, the two hydraulic connecting rods 63 and the piston rod 62 are integrally formed, that is, the entire connecting rod structure forms a T-shape.

[0096] In some embodiments, the oscillation mechanism further includes a drive motor 65, a hydraulic pump, and a hydraulic oil reservoir 66. The hydraulic pump is in oil communication with the hydraulic oil reservoir 66 and the hydraulic cylinder, respectively, and the hydraulic cylinder is in oil communication with the hydraulic oil reservoir 66. The drive motor 65 is configured to drive the hydraulic pump, which draws hydraulic oil from the hydraulic oil reservoir 66 into the hydraulic cylinder, thereby extending the piston rod 62. Conversely, the hydraulic pump draws hydraulic oil from the hydraulic cylinder, causing the piston rod 62 to retract, thereby achieving movement of the piston rod 62 in the first direction X.

[0097] The above lifting mechanism has at least the following advantages:

[0098] The movable flexible member 20 not only propels the head assembly 30 to swing about the hinge axis, thereby achieving the swing of the head assembly 30 relative to the body member 10, but also adapts to the position change of the head assembly 30 through the deformation of the flexible member 20 itself, so that during the swinging process of the head assembly 30, the flexible member 20 can form a stable connection with the head assembly 30, thereby ensuring the stability of the swinging of the head assembly 30. Compared with the traditional swinging mechanism, the above-mentioned swinging mechanism can achieve the swinging of the head assembly 30 by only using a movable flexible member 20, without the need for a complex transmission mechanism, thereby improving space utilization and streamlining the volume of the head assembly 30.

[0099] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
