As shown in fig. 1-4, the present invention provides a guard system for a ceiling fan 300 comprising: a sensing assembly 100 disposed on the fan blades of the ceiling fan 300 and a braking assembly 200 disposed at the switch 400 or at the driver of the ceiling fan 300;
the sensing assembly 100 includes: the device comprises a power supply device 10, a detection device 20 for detecting the distance between a human body or an object and a wireless signal transmitting device 30, wherein the power supply device 10 is electrically connected with the detection device 20 and the wireless signal transmitting device 30, and the detection device 20 is electrically connected with the wireless signal transmitting device 30. It should be noted that each component in the sensing assembly 100 may be fixed to a blade of the ceiling fan 300 when the ceiling fan 300 is manufactured, or the sensing assembly 100 may be fixed to a blade of the ceiling fan 300 after the ceiling fan 300 is shipped.
The brake assembly 200 includes: a brake switch 50 connected to a power supply circuit of the ceiling fan 300, and a wireless signal receiving device 40; the wireless signal receiving device 40 is connected with the wireless signal transmitting device 30 in a wireless communication manner, the wireless signal receiving device 40 is electrically connected with the brake switch 50 and sends a brake signal to the brake switch 50, and the brake switch 50 disconnects the power supply of the ceiling fan 300 according to the brake signal.
It should be appreciated that in the conventional manner, since the fan blades are rotated during operation, the sensing assembly 100 is not disposed on the fan blades of the ceiling fan 300, but rather is disposed at a relatively fixed location on the ceiling fan 300, such that the sensing distance is not particularly precise. In the above embodiment, the sensing assembly 100 is disposed on the fan blades of the ceiling fan 300, and is used for sensing the distance between a person or an object and the fan blades of the ceiling fan 300, so as to achieve more accurate object or human body sensing.
In order to enable the induction assembly 100 to be arranged on the fan blade of the industrial fan, the above embodiment is specifically modified on the fan blade, firstly, the power supply device 10 is arranged, so that the induction assembly 100 can operate independently without external wires, and damage to the reel caused by rotation of the ceiling fan 300 is avoided; in addition, the wireless signal receiving device 40 also does not need an external precedent, thereby further ensuring the independence of the sensing component 100, so that the sensing component 100 can be safely and reliably arranged on the fan blades of the ceiling fan 300.
In order to correspond to the sensing assembly 100 and brake the ceiling fan 300, the above embodiment is further provided with the brake assembly 200, and specifically, in order to brake the ceiling fan 300, the brake assembly 200 includes the wireless signal receiver corresponding to the wireless signal transmitting device 30, and further includes a brake switch 50 connected to a power supply circuit of the ceiling fan 300, so that the fan can be safely braked. In addition, the brake assembly 200 is disposed at the switch 400 or the driver of the ceiling fan 300, so as to facilitate the power-off braking operation of the ceiling fan 300. It should be appreciated that the brake assembly 200 may be electrically connected to an external power source, and a separate power supply device 10 may not be provided.
The working mode of the above embodiment is as follows: when the detecting device 20 detects that a human body or an object approaches the fan blades of the ceiling fan 300, the wireless signal transmitting device 30 electrically connected to the detecting device 20 transmits a braking signal to the wireless signal receiving device 40, after receiving the braking signal, the wireless signal receiving device 40 transmits the braking signal to the braking switch 50 electrically connected to the wireless signal receiving device 40, and then the braking switch 50 disconnects the power supply of the ceiling fan 300 according to the braking signal.
Preferably, the protection system for the ceiling fan 300 further comprises a motor controller 60 or a mechanical stop controller electrically connected to the wireless signal receiving device 40 to reduce the rotation speed of the ceiling fan 300 after power failure. Such as: since the rotation of the ceiling fan 300 cannot be immediately stopped after the brake switch 50 turns off the power supply to the ceiling fan 300, the damage of the ceiling fan 300 to a human body or an object can be further reduced by using the motor controller 60 or the mechanical brake controller. It will be appreciated by those skilled in the art that the motor controller 60 can be used to control the motor at the drive of the ceiling fan 300 to reduce the rotation of the motor to slow down the ceiling fan 300. of course, the mechanical brake controller can more directly control the rotation of the motor or the ceiling fan 300, but direct braking will have some effect on the ceiling fan 300, so that typically, the motor controller 60 is used to further slow down the ceiling fan. In addition, the motor controller 60 and the mechanical brake controller are both required to have a power supply separate from the ceiling fan 300 to ensure that the ceiling fan 300 can be operated after power is cut off.
It should be appreciated that further downshifting using the motor controller 60 or the mechanical brake control must be possible using the brake switch 50 because downshifting is performed directly without a power outage, which does not result in significant damage to the ceiling fan 300 and has poor braking effectiveness.
In order to further ensure that human and objects are not damaged, the protection system for the ceiling fan 300 further comprises an audible and visual alarm device 70 electrically connected with the wireless signal receiving device 40. For better warning, the audible and visual alarm 70 is disposed near the ceiling fan 300. Specifically, the audible and visual alarm device 70 may include one or two of a buzzer and a flashlight.
Further, as a specific description of the present invention, the power supply device 10 includes one or both of a wind power generator and a lithium battery. The detection device 20 is one or more of an infrared distance meter, a capacitive proximity sensor, a radar distance meter and a laser distance meter. The wireless signal transmitting device 30 comprises one or more of an infrared transmitter, a bluetooth signal transmitter and a communication network transmitter; the wireless signal receiving device 40 is adapted to the wireless signal transmitting device 30, and is one or more of an infrared receiver, a bluetooth signal receiver, and a communication network receiver.
In order to improve the sensing accuracy of the sensing assembly 100, a plurality of the sensing assemblies 100 may be respectively disposed on a plurality of the fan blades of the ceiling fan 300, and the plurality of the sensing assemblies 100 are symmetrically distributed on the plurality of the fan blades of the ceiling fan 300. Further, the detecting end of the detecting device 20 may be disposed at a position close to the free end of the fan blade.
As a specific description of any of the above embodiments, it should be further understood by those skilled in the art that the sensing assembly 100 of the present invention is disposed on the fan blade, so as to protect the sensing assembly 100, and at the same time, in order to prevent the sensing assembly 100 from generating wind resistance noise due to the rotation of the ceiling fan 300, the sensing assembly 100 may further include a protective casing for protecting the detecting device 20 and the signal transmitting device, and the casing is fixed on the fan blade; of course, the sensing assembly 100 may be located directly inside the fan blades of the ceiling fan 300 without affecting the production of the ceiling fan 300, as is the case with the fan blades. In addition, in order not to affect the operation of the detecting device 20 and the signal emitting device, the detecting device 20 and the wireless signal emitting device 30 are located between the protective casing and the fan blade, and the detecting end of the detecting device 20 and the emitting end of the wire number emitting device still need to extend to the outer side surface of the protective casing.
In order not to affect the operation of the ceiling fan 300, the protection housing may have an arc shape corresponding to the fan blades, and the sensing assembly 100 with the protection housing should be symmetrically disposed on two symmetrical fan blades to further reduce the influence on the operation of the ceiling fan 300.
