The present invention relates to a suction brush for a vacuum cleaner mounted on a vacuum cleaner, and more particularly to a suction cleaner for a vacuum cleaner in which a human body detecting means is further provided in addition to a conventional suction brush function for a vacuum cleaner.

In general, the vacuum cleaner is a powerful suction force generated by the motor drive is configured to have a function to collect dust or other foreign matter on the floor cleaning surface, the vacuum cleaner has a main body having a dust collecting chamber and a driving chamber partitioned by the inner partition And a suction brush detachably attached to one end to suck in dust on the cleaning surface, and an extension tube including a driving or driving force control unit for the vacuum cleaner motor is detachably attached to the other end so that the air flow path reaches the suction brush. When the suction force is generated by the motor drive of the vacuum cleaner, the suction air is forcedly sucked through the suction brush, and the foreign substances including the dust on the bottom are sucked together with the external air, and then are introduced into the main body of the vacuum cleaner and filtered. .

However, all these types of vacuum cleaners are inconvenient for a person to turn on or operate a motor drive switch, and especially for a shoe vacuum cleaner installed at a front door or an entrance, a person near a certain distance from a suction brush. Prior to this, the suction motor must be operated to reduce the cleaning time and to provide a stable detection of the sensor by dirt in the suction brush.

Accordingly, the present invention has been made in view of the above point, the object of the present invention is to provide a suction brush for a vacuum cleaner including a human body detecting means with a cleaning function due to forced suction.

In order to achieve the above object, in the present invention, the suction brush for a vacuum cleaner detects a change in the static charge detected at a relatively short distance within a few meters of the human detection distance, but respects the environment of the material and the ambient light source change environment. The suction brush for the vacuum cleaner and the vacuum cleaner with integrated suction sensor that can accurately provide the human body detection signal (signal) regardless of the presence of dirt or skin wound while showing the fidelity and reliable human body detection capability to provide.

It will be described in detail with reference to the accompanying drawings.

First, Figure 1 is an external perspective view of the suction brush for the vacuum cleaner of the human body detecting function according to the present invention, Figure 2 is a side sectional view of Figure 1, Figure 3 is an exploded perspective view of Figure 1;

2 to 3, the vacuum suction brush 1 according to the present invention is assembled to be detachable, as shown in the conventional air passage 51 by the assembly structure of the upper case, the lower case 10, 20 ) Is formed of a connection pipe 50 is formed, the upper and lower cases 10, 20, one side of the sensor 31 and the human body detection circuit 30 of the means for detecting the human body is built in the human body It is a suction brush for a vacuum cleaner in which a function of transmitting a detected signal to the outside through a cable 60 extended through the connector 50 is integrated.

As the human body detecting sensor, a superconducting infrared sensor, an infrared sensor, and an electrostatic change detecting antenna for detecting the electrostatic charge of the human body are used to select the aforementioned sensors when a person is near the suction brush for the vacuum cleaner of the present invention. By generating a detection signal by using it can be transmitted to the outside via the signal transmission cable 60 including the power.

Reference numeral 11 is a through hole 11 through which outside air passes.

4 is a view showing an embodiment of a human body detection circuit,

When a human (human body) approaches the antenna 31 as a circuit for detecting a human body composed of a sensor, a change in the static charge of the metal antenna 31 occurs.

In the figure, C1, i.e., the charge, which is indicated by the dotted line at the input of Q1 (FET), changes with the approach of the human body.

This change results in a change in the drain current of Q1 and is amplified by the next amplifier section.

The amplified signal generates a detector or a program signal in a central processing unit (CPU) and a micro controller unit (MCU) circuit configuration in a control circuit to transmit an electrical signal to the outside through the cable 60, and the case 10 In the case where a part of the part 20 is made of metal, the metal part may also be used as the antenna 31.

In addition, Q1 can be replaced with TR, and the human body can be detected simply by a method of detecting a frequency change caused by a charge change.

Thus, the suction brush for vacuum cleaners of the present invention having a human body detecting function is a suction brush for cleaning dirt containing air by a powerful suction force generated by the driving of a motor installed inside the main body, and economically under static electricity by the approach of the human body. It is a suction brush for a vacuum cleaner having a human body detecting function of detecting a human body by a change or transmitting an electronic signal detected by various sensors to the outside through a cable 60.

Since the suction brush for the vacuum cleaner according to the present invention by the configuration as described above has a built-in human body detection of its own function, in the case of a porch or shoe-only vacuum cleaner, there is no inconvenience to operate a separate vacuum cleaner and easy to install or install There is an effect that can realize an unmanned vacuum cleaner system.

The present invention, in particular, when utilized in a shoe-only vacuum cleaner applied to the entrance or entrance, can provide a suction brush for a vacuum cleaner that can turn on / off the vacuum cleaner by unattended automation.

The flashing block described above and illustrated in the drawings is only one embodiment for implementing the present invention, and should not be construed as limiting the technical spirit of the present invention. The scope of protection of the present invention is defined only by the matters described in the following claims, and the embodiments which have been improved and changed without departing from the gist of the present invention will be apparent to those skilled in the art. It will be said to belong to the protection scope of the present invention.
