Description

Inductive anti-collision fan

This creation is about a fan device that can detect the proximity of an object and automatically stop the blade rotation and send a warning message to avoid injury.

At present, fan devices such as electric fans, vertical fans or ceiling fans are generally provided with a rotatable blade, but the blade may be dangerous when it is rotated at a high speed. Although most of the fan units are equipped with a net to ensure the full case, if there are children in the house, the fingers of the child are thin, and it is easy to put the fingers into the net and be cut by the leaves. In addition, when a foreign object touches the blade, it is also likely to cause damage or malfunction of the fan device, so there is a danger of potential use.

Although there is a new type of self-inductive electric fan patent No. M467743 announced by the Republic of China on December 11, 102, it discloses: a body, a control unit and a detector. The body includes a base and a fan unit disposed on the base, the fan unit being rotatable relative to the base. The control unit is communicatively coupled to the fan unit for controlling operation of the fan unit, and the control unit is provided with an effective starting distance. The detector is electrically connected to the control unit for detecting at least an object and a detection distance of the self-inductive electric fan. The control unit controls the fan unit to the off mode when the detection distance is greater than the effective starting distance; and when the detection distance is less than or equal to the effective starting distance, the control unit controls the fan unit to the startup mode.

Although the patent predecessor discloses the function of detecting the distance of an object, it is not used to detect the stop of rotation of a foreign object as it approaches the blade. Therefore, the problems and effects to be solved in the patent case are different from the case.

Accordingly, the present fan device has the above disadvantages. Therefore, this creation provides an inductive anti-collision fan with a body. A power unit is fixed to the base body, and the power unit drives a blade to rotate. At least one detecting unit is disposed on the blade, and the detecting unit detects that an object in proximity within a sensing distance emits a trigger signal. A control unit is disposed in the body, and the control unit is electrically connected to the power unit and the detecting unit respectively. The control unit receives the trigger signal and controls the power unit to stop starting. A warning unit is disposed on the base, and the warning unit is electrically connected to the control unit, and the warning unit is controlled by the control unit to issue a warning message. An input unit is disposed on the base, and the input unit is electrically connected to the control unit, so as to input a preset value of the sensing distance. A power supply unit is disposed in the body, and the power supply unit is electrically connected to the power unit and the control unit respectively, thereby supplying the power unit and the power required for the control unit to operate.

The above seat system is a base of a vertical fan.

The above seat system is a fixed seat of a ceiling fan.

The detecting unit emits an infrared ray or an ultrasonic wave for detection.

When the control unit does not receive the trigger signal, the control unit controls the power unit to start.

The warning unit includes a warning light and a buzzer, the warning message includes the warning light emitting a warning light and the buzzer emitting a warning sound.

The above technical features have the following advantages:

1. When any object approaches the fan, the blade rotation can be stopped immediately, avoiding collisions with the blade causing injury.

2. A warning message can be issued to inform the user to avoid collision with the fan, causing it to be dumped and dangerous.

3. It can be used in general vertical fans or ceiling fans. It has a wide range of uses and excellent practicability.

Referring to the first and second figures, the present embodiment is a vertical fan device including a seat body (1), a power unit (2), at least one detecting unit (3), and a control unit (4). ), warning unit (5), input unit (6) and power supply unit (7), wherein:

The warning unit (5) is electrically connected to the control unit (4), and the warning unit (5) comprises a warning light (51) and a buzzer (52), thereby receiving the control unit (4) The control sends a warning message, the warning message includes the warning light (51) emitting a warning light and the buzzer (52) issuing a warning tone.

An input unit (6) is disposed on the seat body (1). The input unit (6) is electrically connected to the control unit (4), so that an input value can be set to set a preset value of the sensing distance.

A power supply unit (7) is disposed in the base body (1). The power supply unit (7) is electrically connected to the power unit (2) and the control unit (4), respectively, to supply the power required by the power unit (2) and the control unit (4) respectively. The power supply unit (7) can be an external power supply device, a battery or a battery.

In use, as shown in the second and third figures, the seat body (1) is placed at an appropriate position, and then the input unit (6) is input to set a preset value of a suitable sensing distance. The sensing distance is preferably within a detection range of less than 30 cm, so that the object can be prevented from being accidentally touched and stopped by the front surface of the blade (21). After the setting is completed, the power unit (2) can be activated, and the blade (21) can be driven to start rotating, and the detecting unit (3) can also initiate sensing detection.

Once an object (B) approaches and enters the detection range of the sensing distance, it is detected by the detecting unit (3) on the blade (21), and the detecting unit (3) A trigger signal is immediately sent to the control unit (4). After receiving the trigger signal, the control unit (4) controls the warning light (51) of the warning unit (5) to emit a warning light. And controlling the buzzer (52) to emit a warning tone to issue a warning message to the object (B) that is approaching to remind the object (B) or the person around to avoid the object (B) from continuing to approach. Causes danger. At the same time, the control unit (4) also controls the power unit (2) to stop starting, so that the blade (21) stops rotating, preventing the object (B) from continuing to approach and touching the blade (21) to avoid touching. Wounded to the blade (21) or hit the seat (1). When the object (B) leaves the detection range of the sensing distance of the detecting unit (3), the control unit (4) automatically re-controls the power unit (2) to start, so that the blade (21) The rotation is started again. Thus, by detecting whether an object (B) enters within the detection range of the sensing distance, the safety of use can be ensured.
