It becomes detectable.

On the right side of the indicator insertion hole 154, a safety device insertion hole 158 in which the safety device 166 is selectively accommodated is drilled. The safety device insertion hole 158 is drilled into a size corresponding to the outer diameter of the safety device 166 and the safety device by rotating the dust cover 160 in the same manner as the indicator insertion hole 154. 166 can be accommodated inside.

On the other hand, the operation portion 210 is provided at the front end of the connection hose 200. The rear end of the operation unit 210 is gripped by the grip handle 212 protruding to the rear so that the user can be gripped, the front button on the operation button to adjust the power applied amount of the fan motor (not shown) by sliding ( 214 is provided to adjust the suction force of the fan motor.

In addition, the inside of the grip handle 212 (see Fig. 3) is provided with a notification device 220, which is a main component of the present invention. The alarm device 220 is configured to rotate when the safety device 166 operates as described above, and generates vibration by receiving power selectively from the safety device 166. 140) It is possible to recognize the amount of foreign matter inside.

The notification device 220 is a motor 224 to generate a rotational power by rotating the rotary shaft 222 when large power is applied, and a vibrator 226 fixedly mounted on one side of the rotary shaft 222 to cause vibration It is configured to include. That is, the notification device 220 is a vibration motor that generates a rotational force and generates vibration when power is applied.

The motor 224 is generally commonly seen, and the principle of rotating the rotating shaft 222 by the same polarity between the electromagnets that generate a magnetic force upon application of power and the permanent magnets inside the motor 224. It is a power generating device using.

The vibrator 226 has a structure overlapping a plurality of plates formed in a semi-circular shape, and is fixedly mounted so that sliding is restricted to the outer peripheral surface of the rotary shaft 222 so that the rotary shaft 222 rotates at the same time when rotating.

The vibrator 226 is mounted such that the center of gravity of the vibrator 226 moves outward from the rotation shaft 222. That is, when power is applied to the motor 224 and the rotary shaft 222 rotates, the vibrator 226 moves the center of gravity of the motor 224 outward so that vibration occurs in the motor 224. do.

Accordingly, a motor mounting part (reference numeral 216 of FIG. 3) is provided at one side of the grip handle 212 to allow the notification device 220 to be inserted and fixed, and the vibration of the notification device 220 is gripped 212. The motor mounting portion 216 is preferably provided with a size corresponding to the outer appearance of the notification device 220 so that it can be transmitted without noise.

Hereinafter, the operation of the vacuum cleaner configured as described above will be described with reference to FIGS. 2 to 5. Figure 5 is a schematic diagram showing a state of the safety device when the dust collecting notification device employing a preferred embodiment of the present invention in operation.

First, as shown in FIG. 3, the dust collecting cover 160 is rotated upward to mount the dust collecting unit 140 to the dust collecting unit fixing unit 150 in a state where the dust collecting unit 126 is opened. That is, mounting is possible by sliding the fastening piece 142 into the fastening groove 152.

When the dust collecting unit 140 and the dust collecting unit fixing unit 150 are coupled to each other, the dust collecting unit fixing unit 150 is placed on the dust collecting unit 126. At this time, the dust collecting unit 140 is located inside the dust collecting unit 126 and maintains the flow restricted state by the dust collecting unit fixing means 150.

When the installation of the dust collecting unit 140 is completed, the dust collecting cover 160 is rotated counterclockwise to shield the front surface of the main body 100. That is, when the dust collecting part 126 is shielded by the dust collecting cover 160 and at the same time, the inlet 144 drilled into the fastening piece 142 is in contact with the fastener 162 to communicate with each other. The air including the foreign matter introduced through 162 may be introduced into the dust collecting unit 140.

In addition, the indicator 164 is inserted into the indicator insertion hole 154 and communicates with the dust collector 126 by a communication hole (not shown) to detect the pressure inside the dust collector 126.

In addition, the safety device 166 is similarly inserted into the safety device insertion hole 158 by counterclockwise rotation of the dust collecting cover 160, and selectively opens when the pressure inside the dust collecting part 126 rises rapidly. By doing so, it becomes a state which can prevent the overload of a fan motor (not shown).

When the assembly of the vacuum cleaner is completed, the operation button 214 is operated in a state of holding the grip handle 212 to apply power to a fan motor (not shown) inside the main body 100. When power is applied to the fan motor, suction power is generated in the suction nozzle 400 to suck foreign substances on the bottom surface together with air.

The air containing the foreign matter sucked into the suction nozzle 400 is introduced into the dust collecting unit 140 through the extension pipe 300 and the connection hose 200 in turn, and only the foreign matter is selectively picked up by the dust collecting unit 140. The cleaning is performed by filtering with.

On the other hand, when a large amount of foreign matter is collected in the dust collection unit 140 and the air pressure is increased, the safety device 166 maintains the state as shown in FIG. 4, but as shown in FIG. By doing so, the dust collecting part 126 is in communication with the room.

At this time, the lower terminal 169 "fixedly mounted on the upper outer circumferential surface of the shielding unit 168 is in contact with the upper terminal 169 'to apply power to the motor 224 of the alarm device 220 to supply the motor. 224 generates a rotational force, and the vibrator 226 also rotates at the same time by the rotation of the rotary shaft 222.

In addition, vibration occurs in the motor 224 due to the dispersion of the center of gravity generated when the vibrator 226 rotates, and the vibration is transmitted to the grip handle 212, so that the user has a dust collecting unit 140. The amount of foreign matter dust collection therein can be recognized without visual confirmation of the indicator 164.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

For example, in the present invention, the canister type vacuum cleaner is configured as a notification device, but it is of course applicable to an upright type vacuum cleaner.

In addition, in the above embodiment, although the bag-type dust collecting unit is provided as a component for filtering the foreign matter, it is of course applicable to the foreign matter dust collecting method by a cyclone depending on the type of the vacuum cleaner.

Vacuum cleaner according to the present invention as described above, the safety device to prevent the overload of the motor is provided with a notification device for generating a rotational force by receiving power from the safety device when the operation is configured to generate vibration.

Therefore, even when the dust collection amount displayed on the display is not directly checked during the cleaning, foreign matter dust collection amount can be easily recognized by vibration, thereby increasing convenience of use.

In addition, there is an advantage that the damage of the fan motor is prevented by performing the cleaning in the state in which the fan motor frequently generated in the conventional vacuum cleaner is prevented in advance.

In addition, maintenance costs such as repair costs are reduced by preventing damage to the fan motor, so that the user is also expected to improve product satisfaction.
