[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1:

[0031] like Figures 1 to 7 As shown, a multifunctional electrical device includes a main body 1, the main body 1 comprising: The outer casing assembly 2 has a first outer casing vent 201 on its top and a second outer casing vent 202 on its side wall. An air duct 203 is formed inside the outer casing assembly 2 between the first outer casing vent 201 and the second outer casing vent 202. A fan assembly 3 is movably embedded in a housing assembly 2, and the first fan head air outlet 301 of the fan assembly 3 is adapted to be positioned at the first housing air outlet 201, and the second fan head air outlet 302 of the fan assembly 3 is connected to the air duct 203. Functional assembly 4 is built into the air duct 203 and is positioned relative to the fan assembly 3 towards the second housing air outlet 202; The lifting assembly 5 is placed inside the outer shell assembly 2 and drives the fan assembly 3 to move up and down relative to the outer shell assembly 2, so that the fan assembly 3 extends out of the first outer shell air vent 201 to realize the function of sending out air, or, so that the fan assembly 3 retracts into the first outer shell air vent 201 to realize the function of driving the airflow of the air duct 203. The control system 6 is electrically connected to the fan assembly 3, the functional assembly 4, and the lifting assembly 5.

[0032] This electrical device features a simple structure and reasonable design. It is equipped with a fan head that can be raised, lowered, and rotated, allowing the fan head to independently cool the surrounding environment and perform the function of a conventional fan. Alternatively, the fan head can be retracted into the main body 1, forming a circulating air duct 203 within the main body 1. The functional assembly then heats, filters, or dehumidifies the airflow within the air duct 203, achieving the fan function of this type of device. By combining these functions with the fan function, it becomes a multi-functional device suitable for different seasonal needs throughout the year, thus improving its practicality.

[0033] In this embodiment, the functional assembly 4 is a heating core structure 4a. When the fan assembly 3 is retracted into the first outer casing air vent 201, the main body 1 is used as an electric heater.

[0034] The fan assembly 3 includes a fan head 31, a support rod 32, and a lifting base 33. The lifting base 33 is fixed on the lifting assembly 5, and the support rod 32 is fixedly connected to the lifting base 33. The fan head 31 is provided with an up-and-down oscillation mechanism 311. The fan head 31 is rotatably connected to the support rod 32 through the up-and-down oscillation mechanism 311, which drives the fan head 31 to coaxially face the first outer casing air outlet 201 or flip to a horizontal position. This structure allows the fan assembly 3 to blow air towards the outer periphery of the main unit when the fan is in fan function, and when the fan assembly 3 is retracted into the first housing air vent 201, the air direction of the fan assembly 3 can be consistent with the air duct 203, which can improve the efficiency of airflow circulation in the air duct 203.

[0035] The lifting assembly 5 includes a synchronous lifting component and a power component. The synchronous lifting component includes several guide screws 51, which are vertically and evenly distributed on the outer casing assembly 2. The lifting base 33 is movably screwed onto the guide screws 51. The power component drives the guide screws 51 to rotate, thereby driving the lifting base 33 to move up and down between functional position one and functional position two of the outer casing assembly 2. Through the power component and the guide screws 51, the entire fan assembly 3 can rise and fall smoothly, and the structure is stable, with low noise during operation and small space occupation.

[0036] The housing assembly 2 and the fan assembly 3 are respectively provided with a position trigger switch 7 and a trigger block at functional positions one and two. The position trigger switch 7 is electrically connected to the control system 6. The position trigger switch 7 cooperates with the trigger block to switch on and off the working circuit of the up and down oscillation mechanism 311, or / and the fan head 31, or / and the functional assembly 4, or / and the lifting assembly 5. The cooperation between the position trigger switch 7 and the trigger block plays a protective role.

[0037] In this embodiment, the position trigger switch 7 can be a micro switch, a Hall switch, or an inductive switch; the trigger block can be a magnetic block or the lifting base 33 of the fan assembly 3 itself; the up-and-down oscillation mechanism 311 adopts existing technology, mainly including the cooperation of the up-and-down oscillation motor and gears, which will not be described in detail here.

[0038] In many other embodiments, the position trigger switch 7 and the trigger block can be omitted, and the circuit design of the control system 6 can be used to automatically determine the up and down lifting position and the on and off of each working circuit.

[0039] The fan head 31 includes at least a motor 312 and a fan blade 313. The fan blade 313 is connected to the shaft of the motor 312. The motor 312 is electrically connected to the control system 6. The control system 6 controls the motor 312 and the fan blade 313 to rotate in the forward direction when the motor is in fan function, or controls the motor 312 and the fan blade 313 to rotate in the reverse direction when the motor is in fan function.

[0040] The fan head 31 also includes a rear grille 314, a front grille 315, and a motor support housing 316. The motor 312 and the up-and-down oscillation mechanism 311 are disposed inside the motor support housing 316. The motor support housing 316 is connected to the rear grille 314. A second fan head air vent 302 is formed on the rear grille 314. The front grille 315 is connected to the front end of the rear grille 314. The front grille 315 forms a first fan head air vent 301. When the motor 312 and the fan blade 313 are rotating in the forward direction, the first fan head air outlet 301 is the air outlet and the second fan head air outlet 302 is the air inlet; When the motor 312 and the fan blade 313 are rotating in opposite directions, the first fan head air inlet 301 is the air inlet and the second fan head air inlet 302 is the air outlet.

[0041] It also includes a base 8, on which a fixed rotating shaft 81 is provided. The main body 1 is rotatably connected to the fixed rotating shaft 81, and a left-right oscillation mechanism 82 is provided between the base 8 and the main body 1. The main body 1 is driven to oscillate left and right relative to the base 8 through the left-right oscillation mechanism 82. With the above structure, the fan head 31 can oscillate left and right to deliver air, increasing the air delivery range.

[0042] The left and right swaying mechanism 82 adopts existing technology and mainly includes the cooperation of left and right swaying motors and gears, which will not be described in detail here.

[0043] The housing assembly 2 includes: The lower outer shell 21 has a protective net 212 on its top wall that connects to the ventilation duct 203 and the second fan head air vent 302. The lower outer shell 21 has a second outer shell air vent 202 on each side of its side wall. The second outer shell air vent 202 is provided with a perforated protective cover 211. The inner liner 22 is placed inside the lower outer shell 21, and its inner cavity forms an air duct 203. A heating core structure 4a is assembled and connected to the inner liner 22 and is correspondingly arranged with the air vent 202 of the second outer shell. The upper outer casing 23 is connected to the top of the lower outer casing 21, and the upper outer casing 23 and the protective net 212 define a fan cavity 231 for accommodating the fan head 31. The top wall of the upper outer casing 23 is provided with a first outer casing air vent 201 that is clearance-fitted with the fan head 31. The protective cover 211 and the protective net 212 can prevent foreign objects or insects from entering the air duct and affecting the use of electrical equipment.

[0044] The power assembly includes a lifting motor 52, a drive wheel 53 connected to the output shaft of the lifting motor 52, and a driven wheel 54 fixedly connected to each guide screw 51. The drive wheel 53 and the driven wheel 54 are connected in a transmission connection. Both the drive wheel 53 and the driven wheel 54 are pulleys 55, and the drive pulley 55 is connected in a transmission connection to each driven pulley 55 through a transmission belt 56.

[0045] Based on the above structure, the general working process of the main body in Embodiment 1 is as follows: In this embodiment, a position trigger switch 7 can be set on the outer casing assembly 2 at each of the functional positions one and two. When the fan assembly 3 performs the fan function, after it is raised to the functional position one, the lifting base 33 of the fan assembly 3 touches the position trigger switch 7 at the functional position one, so that after the fan assembly 3 reaches the position, the working circuit of the heating core structure 4a and the lifting assembly 5 is cut off, and then the working circuit of the up-and-down oscillation mechanism 311 is started, so that the up-and-down oscillation mechanism 311 drives the fan head 31 to flip downward, the fan head 31 rotates from the vertical state to the horizontal state, and the working circuit of the fan head 31 is switched. At this time, the motor 312 and the fan blade 313 are rotating in the forward direction, the first fan head air outlet 301 is the air outlet, and the second fan head air outlet 302 is the air inlet, so that the fan head 31 blows air forward.

[0046] The fan assembly 3 performs the fan function in two steps: First, cut off the working circuit of the fan head 31 and start the working circuit of the lifting assembly 5 to lower the fan head assembly 3. When the fan assembly 3 leaves the position trigger switch 7 at the first functional position, or before the fan assembly 3 leaves the first functional position, start the working circuit of the up-and-down oscillation mechanism 311 to drive the fan head 31 to flip upward. The fan head 31 rotates from the horizontal state to the vertical state, and the fan head 31 coincides with the axis of the air duct 203.

[0047] Second, the lifting base 33 of the fan assembly 3 touches the second position trigger switch 7, causing the fan assembly to reach the position. The fan head 31 retracts into the fan cavity 231, and the working circuit of the lifting assembly 5 is cut off, stopping the descent. The working circuit of the heating core structure 4a and the working circuit of the switching fan head 31 are connected. At this time, the motor 312 and the fan blade 313 are rotating in opposite directions. The first fan head air outlet 301 is the air inlet, and the second fan head air outlet 302 is the air outlet. The fan head 31 draws outside air into the air duct 203 through the first outer shell air outlet 201 for transportation. After being heated into hot air by the heating core structure 4a, it is discharged from the second outer shell air outlets 202 on both sides, realizing the heater function. Example 2:

[0048] The difference between Example 2 and Example 1 is as follows: Figures 8 to 13 As shown, the main body 1 includes: The housing assembly 2 includes a fixed housing 24 and a movable housing 25. The movable housing 25 is movably nested outside the fixed housing 24. A first housing vent 201 is provided on the top of the movable housing 25, and a second housing vent 202 is provided on the side wall of the movable housing 25.

The movable housing 25 is movably nested outside the fan assembly, and its first housing air outlet 201 is correspondingly arranged with the first fan head air outlet 301 of the fan assembly 3. The second fan head air outlet 302 of the fan assembly 3 is connected to the circulating air duct 203. Functional assembly 4 is disposed inside the fixed housing 24, placed in the circulating air duct 203, and positioned towards the air outlet 202 of the second housing; The lifting assembly 5 drives the movable outer shell 25 to move up and down relative to the fixed outer shell 24, so that the fan assembly 3 is exposed outside the main body 1 to realize the function of blowing air outward, or the movable outer shell 25 is covered on the outer periphery of the fan assembly, and the fan assembly 3 realizes the function of driving the airflow of the circulating air duct 203. The control system 6 is electrically connected to the fan assembly 3, the functional assembly 4, and the lifting assembly 5.

[0049] The fan assembly 3 includes a fan head 31 and a support rod 32. The lower end of the support rod 32 is fixedly connected to the top wall of the fixed housing 24. The fan head 31 is provided with an up-and-down oscillation mechanism 311. The fan head 31 is rotatably connected to the upper end of the support rod 32 through the up-and-down oscillation mechanism 311, and drives the fan head 31 to coaxially face the air outlet 201 of the first housing or to flip to a horizontal position.

[0050] The lifting assembly 5 includes a synchronous lifting component and a power component. The synchronous lifting component includes several guide screws 51, several racks 56, and a number of gears 57 corresponding to the racks 56. The racks 56 are evenly distributed vertically on the inner side of the movable housing 25. The gears 57 are fixed to the fixed housing 24 and mesh with the racks 56. The power component drives each gear 57 to rotate, thereby pushing the movable housing 25 to move up and down between functional position one and functional position two. Through the cooperation of the racks 56 and gears 57, the entire fan assembly 3 can rise and fall smoothly, and the structure is stable, with low noise during operation and small space occupation. The position trigger switch 7 and the trigger block are disposed between the fixed housing 24 and the movable housing 25.

[0051] The fixed outer casing 24 includes an inner casing 213 and a grille protective cover 212 fixed to the top of the inner casing 213. The lower end of the support rod 32 is fixed above the grille protective cover 212. The movable outer casing 25 and the grille protective cover 212 define a fan cavity 231 for accommodating the fan head 31. The side wall of the inner casing 213 is provided with a second outer casing vent 202 on opposite sides. The second outer casing vent 202 is provided with a perforated side cover 211. The side cover 211 and the grille protective cover 212 can prevent foreign objects or insects from entering the circulation duct and affecting the use of electrical equipment.

[0052] The power assembly includes a lifting motor 52, a drive wheel 53 connected to the output shaft of the lifting motor 52, and a driven wheel 54 fixedly connected to the axle of each gear 57. The drive wheel 53 and the driven wheel 54 are connected in a transmission connection. Both the driving wheel 53 and the driven wheel 54 are pulleys. The driving pulley is connected to each driven pulley via a transmission belt 55. Through the belt structure transmission, the rotation speed of each gear can be synchronized, enabling the movable outer shell 25 to move horizontally and vertically smoothly.

[0053] Other structures (such as the fan head and base) are the same as in Embodiment 1, and will not be described in detail in this embodiment.

[0054] Based on the above structure, the general working process of the main body in Embodiment 2 is as follows: In this embodiment, a position trigger switch 7 can be set on the movable housing 25 at each of the functional positions one and two. When the fan assembly 3 performs the fan function, after the movable housing 25 descends to the functional position one, the movable housing 25 touches the position trigger switch 7 at the functional position one, so that the movable housing 25 is nested in the fixed housing 24, cutting off the working circuit of the heating core structure 4a and the lifting assembly 5, and then starting the working circuit of the up-and-down oscillation mechanism 311, so that the up-and-down oscillation mechanism 311 drives the fan head 31 to flip downward, the fan head 31 rotates from the vertical state to the horizontal state, and the working circuit of the fan head 31 is switched. At this time, the motor 312 and the fan blade 313 are rotating in the forward direction, the first fan head air outlet 301 is the air outlet, and the second fan head air outlet 302 is the air inlet, so that the fan head 31 blows air forward.

[0055] The fan assembly 3 performs the fan function in two steps: First, disconnect the working circuit of the fan head 31 and start the working circuit of the up-and-down oscillation mechanism 311, so that the up-and-down oscillation mechanism 311 drives the fan head 31 to rotate upward. The fan head 31 rotates from the horizontal state to the vertical state, and the axis of the fan head 31 coincides with the axis of the circulating air duct 203. Then start the working circuit of the lifting assembly 5, so that the movable outer shell 25 slides upward and covers the outer periphery of the fan head 31. The first fan head air outlet 301 of the fan head 31 stops at the position of the first outer shell air outlet 201.

[0056] Second, the movable outer shell 25 touches the position trigger switch 7 at the second position, so that after the movable outer shell 25 reaches the position, the fan head 31 is built into the fan cavity 231, and the working circuit of the lifting assembly 5 is cut off, stopping the movable outer shell 25 from rising further. The working circuit of the heating core structure 4a and the working circuit of the fan head 31 are connected. At this time, the motor 312 and the fan blade 313 are rotating in opposite directions. The first fan head air outlet 301 is the air inlet, and the second fan head air outlet 302 is the air outlet. The fan head 31 draws outside air into the circulation duct 203 through the first outer shell air outlet 201 for transportation. After being heated into hot air by the heating core structure 4a, it is discharged from the second outer shell air outlets 202 on both sides to realize the heater function. Example 3:

[0057] The structure and principle of Example 3 are basically the same as those of Example 1, with the following differences: Figure 14 As shown, the functional assembly 4 is an air filter structure 4b. When the fan assembly 3 is retracted into the first housing air vent 201, the main body 1 is used as an air filter. Example 4:

[0058] The structure and principle of Example 4 are basically the same as those of Example 1, with the following differences: Figure 15 As shown, the functional assembly 4 is a condenser structure 4c. When the fan assembly 3 is retracted into the first outer casing air vent 201, the main body 1 is used as a dehumidifier. The dehumidification principle of the dehumidifier mainly adopts the working principle of the refrigeration system. The condenser structure 4c is one of the components of the refrigeration system, and it also includes components such as a compressor pump and an evaporator. It can also be used in conjunction with a water collection box structure. The above-mentioned refrigeration system belongs to the prior art and will not be described in detail or referenced in the accompanying drawings in this embodiment. Example 5:

[0059] The structure and principle of Embodiment 5 are basically the same as those of Embodiment 1. The difference is that the functional assembly 4 includes one or more combinations of heating core structure 4a, air filter structure 4b, and condenser structure 4c. For example, when the fan assembly 3 is retracted into the first outer casing air vent 201, the main body 1 can be used as a heater or an air filter. It can also perform air filtration function while performing heating function. The heating core structure 4a and the air filter structure 4b are arranged in front and behind along the circulation air duct 203. This embodiment is not shown in the accompanying drawings.
