[0054] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0055] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in 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 a central 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 a central element at the same time. 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 implementation method.

[0058] Referring to FIG. 1 , a household appliance provided in an 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 hinged portion 31 and a fixed portion 32, the hinged portion 31 and the fixed portion 32 are arranged at intervals along a second direction Y, and the hinged portion 31 is hinged to the body member 10 around 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 fixing portion 32 to move along the first direction X, thereby driving the head assembly 30 to rotate around the hinge axis, thereby realizing the swing of the head assembly 30 relative to the body 10. In addition, due to the deformable characteristics of the flexible member 20 itself, when the head assembly 30 rotates relative to the body 10, the flexible member 20 will stretch or compress itself according to the different positions of the head assembly 30 to adapt to the position change of the lens assembly.

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

[0062] When the flexible member 20 moves upward relative to the hinge 31, as shown in FIG3 , the flexible member 20 will push the head assembly 30 to rotate counterclockwise around the hinge axis to achieve an upward head shake. At this time, the center of the head assembly 30 gradually deviates toward the hinge 31, and the head assembly 30 will tend to continue to move counterclockwise under the action of gravity. For this reason, the flexible member 20 will stretch to balance the gravity of the head assembly 30 through the elastic force of the flexible member 20 itself.

[0063] On the basis of FIG2 , when the flexible member 20 moves downward relative to the hinge 31, as shown in FIG4 , the flexible member 20 will push the head assembly 30 to rotate counterclockwise around the hinge axis to achieve a downward head movement. At this time, the center of the head assembly 30 gradually deviates toward the flexible member 20, thereby increasing the pressure on the flexible member 20. To this end, the flexible member 20 will be compressed to adapt to the pressure applied by the head assembly 30.

[0064] In this way, the movable flexible member 20 not only pushes the head assembly 30 to swing around the hinge axis, thereby realizing 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 shaking mechanism, the above shaking mechanism can realize the swinging of the head assembly 30 by only using a movable flexible member 20, without setting a complex transmission mechanism, thereby improving space utilization and simplifying the volume of the head assembly 30.

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

[0066] In some other embodiments, the household appliance may also be a heater. When the household appliance is a heater, the head assembly 30 may be a component that outputs radiant heat, and the head assembly 30 swings through the flexible member 20 so that the radiant heat can cover more space, thereby improving the user experience. In some other embodiments, the household appliance may also be a humidifier or air purifier that requires shaking its head.

[0067] In some embodiments of the present application, referring to FIG. 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 at a greater angle around the hinge axis, so that the angle of the head assembly 30 is more flexible.

[0068] Specifically, referring to Figures 5, 6 and 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 the like.

[0069] In some embodiments, the body part 10 is further provided with an accessory cavity 11, and the household appliance further comprises a working accessory 41, which is arranged in the accessory cavity 11 to cooperate with the head assembly 30 to work, so that the head assembly 30 can 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 head assembly 30, so that the water in the water tank 42 can be input into the head assembly 30, and atomized to form water vapor in the head assembly 30, and finally the water vapor acts on the human body together with the airflow generated by the head assembly 30, so that the cooling effect on the human body surface is more obvious.

[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 is provided with an escape hole 21, which is connected to the accessory cavity 11, and when the fixing portion 32 is connected to the flexible member 20, the head assembly 30 closes the escape hole 21. That is, when the fixing portion 32 is connected to the flexible member 20, the head assembly 30 covers the end of the escape hole 21, so that the escape hole 21 is in a closed state. When the escape hole 21 is closed, the working accessory 41 can be kept in the accessory cavity 11 and is not easy to escape from the escape hole 21, thereby ensuring the stability of the position of the working accessory 41 when the household appliance is working normally, so that the head assembly 30 can work normally.

[0072] When the fixing part 32 is separated from the flexible part 20, the head assembly 30 can open the avoidance hole 21 during the movement of the head assembly 30 relative to the body part 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, 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, thereby facilitating the user to refill the water tank 42 alone.

[0074] When the user has finished refilling the water tank 42, the water tank 42 can be aligned with the avoidance hole 21, so as to return the water tank 42 to the accessory cavity 11, and then the head assembly 30 is rotated to a position where the flexible member 20 and the fixing portion 32 can be fixed to each other, and after the flexible member 20 and the fixing portion 32 are fixed to each other, the head assembly 30 can work 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 limiting member 15 is also provided on the body member 10, and the limiting member 15 is located in the accessory cavity 11. When the working accessory 41 enters the accessory cavity 11, it can abut against the limiting member 15, and the limiting member 15 prevents the working accessory 41 from continuing to move, so that the working accessory 41 can be fixed at the position abutting against the limiting member 15, that is, the working accessory 41 can be installed in place through the limiting member 15. Moreover, when the user is installing the working accessory 41, when the user finds that the working accessory 41 cannot continue to move, it can be understood that the working accessory 41 has been installed in place, and the user can then turn the head assembly 30 to close the avoidance hole 21, and connect the flexible member 20 to the fixing portion 32, and then the household appliance can be used normally.

[0076] In some embodiments of the present application, referring to FIG8 , in order to achieve connection and separation between the fixing portion 32 and the flexible member 20, a fixing hole 33 is provided on the fixing portion 32, and a supporting hole 22 is provided on the flexible member 20. During the movement of the head assembly 30 around the hinge axis, the fixing hole 33 can be aligned with the supporting hole 22, and both extend longitudinally along the direction of the hinge axis. The shaking mechanism also includes a latch 50, and when the fixing hole 33 and the supporting hole 22 are aligned with each other, the latch 50 can be inserted into the fixing hole 33 and the supporting hole 22.

[0077] Thus, when the latch 50 is inserted into the fixing hole 33 and the supporting hole 22, the latch 50 will restrict the fixing portion 32 from rotating relative to the flexible member 20, thereby fixing the head assembly 30 to the flexible member 20 and the body member 10. When the latch 50 is separated from at least one of the fixing hole 33 and the supporting hole 22, the latch 50 will not be able to restrict the fixing portion 32 from rotating relative to the flexible member 20, and the head assembly 30 can be controlled to rotate.

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

[0079] In this way, the elastic member 51 allows the latch 50 to separate from the support hole 22 only 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 be easily separated from the support hole 22, thereby ensuring the reliability of the connection between the fixing portion 32 and the flexible member 20. In addition, since the latch 50 is fixed to the fixing member, the latch 50 will still remain on the fixing portion 32 even after the user controls the fixing portion 32 to separate from the flexible member 20. Compared with the method in which the latch 50 is separated from both the support hole 22 and the fixing hole 33, the latch 50 is not easily lost and is more convenient for the user to operate.

[0080] Furthermore, in order to facilitate user operation, the latch 50 further includes an operating end 53, the operating end 53 and the extending end 52 are arranged at opposite ends of the latch 50, and the operating end 53 extends out of the fixing hole 33, so that the user can grab the operating end 53 to pull the latch 50, so that the extending end 52 retracts into the fixing hole 33, and then the latch 50 is separated from the supporting hole 22, and the fixing part 32 is separated from the flexible part 20. When the user releases the operating end 53, the latch 50 will extend the extending end 52 under the action of the elastic part 51, and then the extending end 52 is inserted into the supporting hole 22, completing the connection between the fixing part 32 and the flexible part.

[0081] Optionally, the elastic member 51 is a spring, which is sleeved on the latch 50, and a limiting protrusion 54 is provided on the latch 50, and the two ends of the spring are respectively abutted against the limiting protrusion 54 and the bottom wall of the fixing hole 33. In addition, a spring stopper 17 is provided on the fixing portion 32, and a stopper hole is provided on the spring stopper 17, and the latch 50 is passed through the stopper hole, and the diameter of the stopper hole is smaller than the limiting protrusion 54, so that the latch 50 can be prevented from falling out of the fixing hole 33 through the spring stopper 17.

[0082] In some other embodiments, the latch 50 can also be set on the flexible member 20, that is, the latch 50 can be telescopically arranged in the support hole 22, and the elastic member 51 is arranged between the flexible member 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 the extended end 52 retracting relative to the support hole 22, the elastic member 51 accumulates an elastic force for extending the extended end 52.

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

[0084] In actual use, if the user is not satisfied with the angle of the head assembly 30, the head assembly 30 may be violently twisted. In order to avoid damaging the driving member 60 by violently shaking the head, in some embodiments, the driving member 60 is a hydraulic cylinder having a piston rod 62 that moves along the first direction X, and the piston rod 62 is connected to the flexible member 20, so that the flexible member 20 is driven to move along the first direction X through the hydraulic cylinder.

[0085] Because the hydraulic cylinder has 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] Specifically in some embodiments, referring to FIG9, FIG10 and FIG11, the shaking mechanism further includes a lifting support member 61, which is movably mounted on the body member 10 along the first direction X, and 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 drive the flexible member 20 to move along the first direction X, thereby pushing the head assembly 30 to shake its head.

[0087] In actual use, the head assembly 30 is arranged at the top of the body member 10, which is at a long distance from the driving member 60. Therefore, the flexible member 20 is arranged on the lifting support member 61, which can reduce the length of the flexible member 20 and reduce the production cost. Optionally, a mounting groove is provided 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] Further, a mounting hole 16 is provided on the top of the fuselage member 10, the mounting hole 16 is connected to the accessory cavity 11 inside the fuselage member 10, the lifting support member 61 is penetrated through the mounting hole 16 and extends out of the mounting hole 16, and the flexible member 20 is installed on the portion of the lifting support member 61 extending out of the mounting hole 16. A connecting hole 64 is provided inside the lifting support member 61 and is arranged to penetrate along the first direction X, one end of the connecting hole 64 is connected to the avoidance hole 21 on the flexible member 20, and the other end is connected to the accessory cavity 11, and the working accessory 41 can pass through the avoidance hole 21 and the connecting hole 64 in sequence to enter the accessory cavity 11, or pass through the connecting hole 64 and the avoidance hole 21 to leave the accessory cavity 11.

[0089] Furthermore, in order to facilitate driving the lifting support member 61, the driving member 60 is also arranged in the accessory cavity 11, so that 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 the lifting support member 61 and the flexible member 20 are both disposed at the top of the fuselage member 10, the flexible member 20 is prone to cause the head assembly 30 to collide with the top of the fuselage member 10 during the process of driving the head assembly 30 to move downward. Therefore, in order to prevent the fuselage member 10 from interfering with the rotation of the head assembly 30, in some embodiments, the fuselage 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 is disposed on the base 40, the first end 12 is hinged to the hinge portion 31, and in the second direction Y and in the direction away from the hinge portion 31, the distance between the first end 12 and the second end 13 gradually decreases.

[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 is reduced is exactly the direction in which the head assembly 30 swings downward. The reduced height of the fuselage part 10 can just be used to accommodate the head assembly 30 that swings downward, thereby preventing the fuselage part 10 from interfering with the movement of the head assembly 30.

[0092] Specifically, in one embodiment, the body member 10 has an oblique cut 14 on the first end 12, and the oblique cut 14 has a highest point and a lowest point in the first direction X, the highest point and the lowest point are arranged at intervals along the second direction Y, and the lowest point is located on the side of the highest point away from the hinge 31. In this way, the height of the body member 10 at the oblique cut 14 is gradually reduced to free up space for the downward swinging movement of the head assembly 30.

[0093] Furthermore, the shell of the head assembly 30 is a cylinder, and during the movement of the head assembly 30 with the flexible member 20, the shell of the head assembly 30 may contact the edge of the bevel cut 14 of the body member 10. In order to make the contact between the head assembly 30 and the edge of the bevel cut 14 smoother, 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 surface, and the surface of the shell of the head assembly 30 is also an arc surface. The contact between the arc surfaces can make the head assembly 30 more compatible with the contact between the ports 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 member 61, so that the driving force of the piston rod 62 can be 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 member 61, so that the lifting support member 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 rod 63 includes two, and 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 hole, so that the lifting support member 61 is 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 is in a T shape.

[0096] In some embodiments, the shaking mechanism further includes a driving motor 65, a hydraulic pump, and a hydraulic oil tank 66. The hydraulic pump is respectively connected to the hydraulic oil tank 66 and the hydraulic cylinder oil circuit, and the hydraulic cylinder is connected to the hydraulic oil tank 66 oil circuit. The driving motor 65 is used to drive the hydraulic pump to operate, and the hydraulic pump draws the hydraulic oil from the hydraulic oil tank 66 into the hydraulic cylinder, thereby driving the piston rod 62 to extend. On the contrary, the hydraulic pump draws the hydraulic oil in the hydraulic cylinder, and the piston rod 62 will retract, thereby realizing the movement of the piston rod 62 along the first direction X.

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

[0098] The movable flexible member 20 not only pushes the head assembly 30 to swing around the hinge axis, thereby realizing 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 shaking mechanism, the above shaking mechanism can realize the swinging of the head assembly 30 by only using a movable flexible member 20, without setting a complex transmission mechanism, thereby improving space utilization and simplifying the volume of the head assembly 30.

[0099] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
