The present invention relates to a sensing device that is a water-light emitting device of a vacuum cleaner, and in particular, installs a rotor on the front surface of the light emitting device, removes dirt formed on the rotor, and removes dirt caught on the front surface of the water-light emitting device by nothing. This eliminates the need to increase the detection of water-emitting devices.

A vacuum cleaner generally used includes a collecting bag 20 and a suction motor 21 as shown in FIG. 1, which includes a hose 23 and a hose 23 connected to one side of the vacuum cleaner main body 22. At the other end of the handle), the handle part 1 can be smoothly grasped during the cleaning operation, and the other side of the handle part 1 is connected to a plurality of connection pipes 24 and the connection pipes 24. In the vacuum cleaner consisting of a commercial suction port 25 on one side of the water, the sensor is made of a light emitting element that is addressed to the printed circuit board for controlling the rotational strength of the suction motor by detecting the amount of dirt sucked when using the vacuum cleaner. The sensor is installed in the front side of the handle part.

As shown in FIG. 2, the upper cover 2 and the lower cover 3 are provided, and the sensing device includes a light emitting device 4 emitting light to the upper cover 2, and a lower cover 3. Light receiving elements 5 for collecting light are respectively installed and mounted on a printed circuit board 8 for controlling the light emitting elements 5 and 4.

That is, the water emitting device 5, 4 is formed in the lower portion of the handle (1) and is built to face each other centered around the distribution hole (7) through which dirt can pass, the number impregnated as described above. In order to protect the light emitting elements 5 and 4, the element cover 6 is made of a transparent material.

In the conventional water and light emitting device configured as described above, when a vacuum cleaner is supplied with power, dirt is sucked into the collecting bag of the vacuum cleaner through a distribution hole. In the sensing, the amount of light reaching the light emitting element mounted on the printed circuit board is sensed.

That is, if the amount of dirt sucked in the vacuum cleaner is large, the light emitted from the light emitting device reaches the light receiving element by a large amount of dirt, and if the amount of dirt is small, a large amount of light reaches the light receiving element and the vacuum The vacuum and strength of the vacuum cleaner will be controlled.

The dirt suction detection device formed as described above has been a factor that degrades the detection ability of the light emitting device due to the number of dirt or foreign matter stacked on the device cover that protects the light emitting device. It is a cumbersome situation for a skilled technician to remove the dirt stacked on the element cover.

The present invention was conceived in view of the above problems, the number of rotors are formed integrally with the rotor blade and the dirt removal rubber, can be rotated in the outer edge of the optical element, and installed by the suction force of the air flowing into the distribution hole By rotating the rotor of the water to remove the dirt, it is possible to remove the dirt stacked on the front of the light emitting device is to increase the detection ability of the water, the light emitting device.

When the present invention is described in more detail, as shown in FIGS. 3 and 4, the air and the dust sucked in have a distribution hole 7 through which the trapezoidal insertion hole ( Upper and lower lids 2 and 3 and 2a and 3a and storage chambers 2b and 3b, a printed circuit board 8 having a number and light emitting elements 5 and 4, and the number and light emitting elements Located at the outer edge of 5,4, and has a plurality of rotary blades 12 and the insertion hole (11a) for inserting the light receiving element 5 or the light emitting element 4 in the axial direction, the insertion hole ( A rotor 11 having a plurality of protrusions 13 on the outer periphery of the side surface of the main body 11b having a trapezoidal cross section while having a dirt removal rubber 14 on the top of 11a) and the rotor 11. The upper and lower lids (2, 3) of the insertion hole (2a, 3a) of the separation is made of a fixing plate 15 for fixing the number, the light emitting elements (5, 4).

That is, the rotor 11 is rotated by the rotary blades 12 formed integrally with the suction force of the air flowing through the distribution hole 7 so that the dirt adheres to the front surface of the light emitting elements 5 and 4. As the removal rubber 14 rotates, the front and rear surfaces of the light emitting devices 5 and 4 are cleaned.

In addition, the projection 3 formed on the side of the rotor 11 is in contact with the contact surface (2a ', 3a') of the insertion hole (2a, 3a) formed in the upper, lower cover (2, 3) to increase the contact tension It is to reduce the smooth rotation.

When the power is supplied to the vacuum cleaner as described above, the air is sucked in by the suction motor built in the vacuum cleaner body, and water is collected in the lower part of the handle part, and dirt is collected together with the air through a distribution hole in which the light emitting element is built. In this case, the suction force rotates the rotor blades integrally formed with the rotor, and the dirt removal rubber formed in the insertion hole of the rotor blades is removed to remove the dirt stacked on the front surface of the light emitting device.

At this time, the projection is in contact with the contact surface of the upper and lower cover insertion hole and maintains the minimum contact tension, so that the rotor rotates smoothly and can be used for a long time, and can remove the dirt stacked on the front surface of the light emitting device from time to time. By accurately detecting the amount of dirt introduced into the vacuum cleaner by the light emitting device, there is an effect of preventing malfunction of the vacuum cleaner.
