DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

In order to make the objective, the technical solution and the advantages of the present application more clearly, the present application will now be described in detail with reference to the accompanying drawings and embodiments. It should be understood that, the specific embodiments described here is only used for explanation, not for limitation.

Figs. 1-4 show a fan apparatus 100 according to one embodiment of the present application. As is shown in Figs. 1-4, the fan apparatus 100 substantially includes a fan unit 10 and an electrical connection support 20. In this case, the fan unit 10 is detachably and electrically connected to the electrical connection support 20 via a magnetic connection assembly 30. In this case, in the embodiment shown in Figs. 1-4, the electrical connection support 20 is a mobile power, in such a way that the electrical connection support 20 can supply power to the fan unit 10. In a further embodiment, the electrical connection support 20 may be further connected to an external power, such as battery power system of a car, an external socket or the like, and thus the fan unit 10 can be powered by external power.

As is further shown in Fig. 4, in this embodiment, when using the magnetic connection assembly 30 to connect the fan unit 10 to the electrical connection support 20, the fan unit 10 is rotatable with respect to the electrical connection support 20 and further electrically connected to the electrical connection support 20 by means of magnetic coupling; in this way, the fan unit 10 is capable of being connected to the electrical connection support 20 in any angle ranged from 0° to 360°, meanwhile the electrical connection support 20 can supply power rapidly to a fan controlling circuit 16 (as is shown in Fig. 5) of the fan unit 10. Therefore, the fan unit 10 can be powered without needing to accurately align with the electrical connection support 20, and the fan unit 10 can rotate to any angle ranged from 0° to 360° with respect to the electrical connection support 20. Accordingly, it is convenient to use the fan apparatus 100 of this type.

In specific, as is shown in Figs. 1-4, in this embodiment, the fan unit 10 substantially includes a fan body 11 and a base 12 connected to an end of the fan body 11. In this embodiment, the fan body 11 is pivotally connected to the base 12 via a pivot axis 13, in such a way that the fan body 11 is pivotable with respect to the base 12 about the pivot axis 13 to an angle ranged from 0° to 180°, in order to adjust the angle of the fan body 11 and thereby choosing a required air-blowing angle. Therefore, the aforesaid arrangement makes it possible for the fan unit to achieve a 360-degree rotation on the plane parallel to the electrical connection support 20, and can achieve a 180-degree pivot about the pivot axis 13 in the three-dimension space. In this way, the fan apparatus of the present application can blow out air to any object without dead angle, and thus the fan apparatus can achieve a same blowing effect as the household fan.

In specific, as is shown in Fig. 2, the magnetic connection assembly 30 substantially includes a first magnetic element 31 and a second magnetic element 32 magnetically coupled to each other. In this way, on one hand, the fan unit 10 is electrically connected to the electrical connection support 20; on the other hand, the fan unit 10 is rotatable about a geometric center of the first magnetic element 31 with respect to the electrical connection support 20.

In this case, the first magnetic element 31 is arranged on one side of the base 12 that is close to the electrical connection support 20, and exposed to an external surface of the base 12. In one embodiment, a surface of the first magnetic element 31 that is in contact with the second magnetic element 32 is at the same level with the external surface of the base 12 that is close to the electrical connection support 20. The second magnetic element 32 is arranged on one side of the electrical connection support 20 that is close to the base 12, and exposed to an external surface of the electrical connection support 20. Further, a surface of the second magnetic element 32 that is in contact with the first magnetic element 31 is at the same level with the external surface of the electrical connection support 20 that is close to the base 12. In addition, one side of the first magnetic element 31 that is close to the electrical connection support 20 has a polarity opposite to one side of the second magnetic element 32 that is close to the base 12. In this way, it is possible for the first magnetic element 31 to be magnetically coupled to the second magnetic element 32, no matter what angle the fan unit 10 is rotated to with respect to the electrical connection support 20. Thereby, the fan unit 10 is fixedly fastened to the electrical connection support 20 via the base 12, and meanwhile the fan unit 10 is electrically connected to the electrical connection support 20, and thus the fan unit 10 can be supplied with power.

It should be noted that, the alignment of the first magnetic element 31 and the base 12, and the alignment of the second magnetic element 32 and the electrical connection support 20 can ensure that the fan unit 10 is directly in contact with the electrical connection support 20, and thus it is possible to prevent a cantilever from forming by the first magnetic element 31 and the second magnetic element 32, thereby the service life of the fan apparatus is extended. Of course, it should be appreciated that, any other suitable means can also be used to replace the magnetic connection assembly 30, for example, the fan unit may also be charged by means of wireless charging.

In addition, the first magnetic element 31 and the second magnetic element 32 may be made from conductive materials, such as steel, alloy or the like. In this embodiment, the first magnetic element 31 and the second magnetic element 32 are permanent magnets. In this way, when the first magnetic element 31 and the second magnetic element 32 are magnetically coupled to each other, the fan unit 10 is electrically connected to the electrical connection support 20, and thus the power supply of the fan unit 10 can be achieved.

As is further shown in Figs. 1-4, and combining with Fig. 5, in this case, the electrical connection support 20 further includes a connection controlling circuit 21 and a connection switch 22 connected between the connection controlling circuit 21 and the first magnetic element 31. When the connection switch 22 is switched on, the circuit between the connection controlling circuit 21 and the first magnetic element 31 is conducted; while the connection switch 22 is switched off, the circuit between the connection controlling circuit 21 and the first magnetic element 31 is cut off. The connection switch 22 in this case is a push button. When the electrical connection support 20 is a mobile power, the electrical connection support 20 further includes a mobile battery 23. The mobile battery 23 is electrically connected to the connection controlling circuit 21, the connection controlling circuit 21 is configured for controlling the discharging of the mobile battery 23.

The working principle of the fan apparatus is described with accordance to Fig. 5; in this case, the electrical connection support 20 is a mobile power. As is shown in Fig. 5, the fan unit 10 further includes a built-in battery 14 configured for independently supplying power to the fan unit 10 when the fan unit 10 is separated from the electrical connection support 20. In this case, the built-in battery 14 is received in the base 12. The built-in battery is preferably a charging battery.

As is further shown in Fig. 5, the fan unit 10 further includes a power controlling circuit 15, a fan controlling circuit 16 and a sensor 17. In this case, the power controlling circuit 15, the fan controlling circuit 16 and the sensor 17 are all received in the base 12.

In this embodiment, the sensor 17 is a current sensor configured for detecting current information of circuits and sending the current information to the power controlling circuit 15. The power controlling circuit 15 is electrically connected to the built-in battery 14, and thus the power controlling circuit 15 can be always powered by the built-in battery 14. In addition, the power controlling circuit 15 is further electrically connected to the sensor 17; in this way, the power controlling circuit 15 can control which power (built-in battery 14 or mobile power) may supply power to the fan controlling circuit 16 according to the detected result (in this case, the detection result is the current information) of the sensor 17. The fan controlling circuit 16 is electrically connected to the built-in battery 14 and the second magnetic element 32, and is powered by the built-in battery 14 or the mobile power. The fan controlling circuit 16 is configured for controlling the on-off state, oscillation, timing, air speed of the fan unit according to operations input by a user. In this case, for example, an electric-control switch 141 (a relay is preferred) is provided between the fan controlling circuit 16 and the built-in battery 14. The electric-control switch 141 is further electrically connected to the power controlling circuit 15. In this way, the power controlling circuit 15 controls an on-off state of the electric-control switch 141, which in turns control the circuit between the built-in battery 14 and the fan controlling circuit 16 to be conducted or cut off.

As is further shown in Fig. 5, in this case, the sensor 17 is arranged between the connection controlling circuit 21 and the first magnet 31. The sensor 17 is configured for detecting the current information of the circuit between the connection controlling circuit 21 and the first magnetic element 31, and sending the detected result to the power controlling circuit 15. The power controlling circuit 15 controls the on-off state of the circuit between the fan controlling fan 16 and the built-in battery 14 according to the detected result. Of course, in other case, the sensor 17 may be arranged between the second magnetic element 32 and the fan controlling circuit 16.

As is further shown in Figs. 3-4, in this case, the fan unit 10 further includes a toggle button 18 and a speed regulating assembly 19 arranged on the base 12. In this case, the toggle 18 is electrically connected between the built-in battery 14 and the power controlling circuit 15, and configured for controlling the on-off state of the circuit between the power controlling circuit 15 and the built-in batter 14, and thereby controlling the on-off state of the whole fan apparatus.

The working principle of the fan apparatus 100 is briefly described with accordance with Figs. 1-5.

When the connection switch 22 is switched on, the circuit between the connection controlling circuit 21 and the first magnetic element 31 is conducted. The sensor 17 detects the current information of the circuit, and determines that whether a current is formed in the circuit. If no current is detected, then the circuit of the whole fan apparatus has not been conducted (for example, the first magnetic element 31 has not yet been magnetically coupled to the second magnetic element 32, or the toggle button 18 has not yet been pressed down) . At this time, the connection controlling circuit 21 controls the mobile battery 23 in the mobile power to stop discharging after a preset period of time (for example, 5s～10s) .

When a current is detected by the sensor 17, it can be seen that, the first magnetic element 31 is magnetically coupled to the second magnetic element 32, and the toggle button 18 is pressed down at this time, and thus the circuit between the fan controlling circuit 16 and the connection controlling circuit 21 is conducted. At this time, the power controlling circuit 15 controls the circuit between the fan controlling fan 16 and the built-in battery 14 to be cut off according to the detected result, and the connection controlling circuit 21 further controls the mobile battery 23 to supply power to the fan controlling circuit 16.

When the connection switch 22 is switched off, the circuit between the connection controlling circuit 21 and the fist magnetic element 31 is cut off. In this case, no current can be detected by the sensor 17. If the toggle button 18 is pressed down, the power controlling circuit 15 controls the circuit between the fan controlling fan 16 and the built-in battery 14 to be conducted, and thus the fan controlling circuit 16 is powered by the built-in battery 14.

In addition, in this case, a hook, a chuck, or a rotation disc may be assembled to the electrical connection support 20, or the electrical connection support 20 may be further connected to an external power, such as a power system of a vehicle or the like, in order to adapt to different service environments and meet different usage requirements. In this case, the hook, chuck or the rotation disc is assembled on a surface of the electrical connection support 20 that is away from the fan unit 10.

Accordingly, when using the fan apparatus 100 of this type, since the fan unit 10 is detachably and electrically connected to the electrical connection support 20 via the magnetic connection assembly 30 or other suitable assembly, the electrical connection support 20 can be always electrically connected to the fan unit 10 even though the fan unit 10 is rotated with respect to the electrical connection support 20 to any angle ranged from 0° to 360°, and thus the fan unit 10 can be powered in any case. In addition, the fan apparatus 100 can further achieve a downwardly air-blowing which can not achieved by a common fan, and thus the air can be distributed in any direction, as is shown in Fig. 6.

Figs. 7-8 further show a portable household fan 200 according to one embodiment, and the portable household fan 200 has the fan apparatus 100 described above. In this case, as is shown in Figs. 7-8, the portable household fan 200 substantially includes two aforesaid fan apparatuses 100. The electrical connection supports 20 respectively of the two fan apparatuses 100 are fixedly connected to each other and supported one another via an external connection assembly 40, and thus two fan apparatuses 100 may be firmly placed on a working platform (not shown here) when the electrical connection support 20 is disposed in a direction parallel to the gravity direction. In this case, the connection assembly 40 includes but not limits to a complementary structure including a positioning element and a positioning hole, a snapping element and a snapping hole, a projection and a recess, and the like. The connection assembly 40 may further be an adhesive structure including Velcro strips. Of course, in other embodiment, it is also possible for the electrical connection supports 20 respectively of the two fan apparatuses 100 to be directly abutted against each other.

As is shown in Fig. 9, the portable household fan 200 further includes a rotatable seat 400, and the electrical connection supports 20 respectively of the two fan apparatuses 100 are respectively inserted into the rotatable seat 400 in a direction perpendicular to the fan unit. After the fan apparatus 100 is inserted into the rotatable seat 400, the fan apparatus 100 is capable of rotating freely since the rotatable seat 400 is rotatable freely; the fan apparatus 100 can be rotated even though the rotatable seat 400 is hung on a wall.

As is further shown in Fig. 9, the rotatable seat 400 has a power port 410 which is configured for connecting to an external power source, and a slot allowing the electrical connection support 20 to insert therein. The rotatable seat 400 is configured for electrically connected to the external power source and further supplying power to the mobile battery inside the electrical connection support 20, or directly supplying power to the built-in battery inside the fan unit.

Fig. 10 provides a portable household fan 200 according to a further embodiment, and the portable household fan 200 has the fan apparatus 100 described above. As is shown in Fig. 10, in this case, a sprinkler 300 is further arranged on one side of the electrical connection support 20 that is away from the working platform. In this case the sprinkler 300 substantially includes an inlet tank 310, and an inlet passage 320 formed between the inlet tank 310 and the fan unit 10 of the fan apparatus 100. In this way, the water inside the inlet tank 310 flows through the inlet passage 320 and is further provided to the fan unit 10. In this way, the water inside the inlet tank 310 can be sprayed out when the fan unit 10 is working, and thus the air is humidified, and it can achieve a better cooling effect when using the fan apparatus of this type. In this case, the inlet tank 310 is substantially in shape of a funnel, and a storage tank 330 may be further connected to the inlet tank 310. In this case, the storage tank 330 is located above the inlet tank 310, and thus the water inside the storage tank 330 may be supplied to the inlet tank automatically due to the gravity. In addition, a spray nozzle (not shown) is further provided on one end of the inlet passage 320 that is away from the inlet tank.

The portable household fan 200 described above has two fan apparatuses 100. However, it should be understood that, in other embodiments of the present application, the portable household fan 200 may include three, four and more fan apparatuses 100. At this time, a plurality of fan apparatuses 100 may be connected to each other and supported one another by extra connection assemblies.

The fan apparatus 100 of the present application can be used individually, or a plurality of fan apparatuses 100 may be used in any combination. During the power supplying, within the adhesive force of the magnetic connection assembly, the fan unit can be connected to the electrical connection support automatically and rapidly without any precise alignment. Beside, the fan apparatus can blow air without any dead corner; the power and functions thereof can comparable with a household fan. Beside, the fan apparatus of the present application has much better performances than the common-used household fan in aspect of practicability, portability, energy saving and the like.
