DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner,
In particular, it relates to a dust sensor unit that can be easily attached to a general-purpose vacuum cleaner.

[0002]

2. Description of the Related Art Some recent vacuum cleaners are of a type capable of detecting the amount of dust being sucked and displaying the amount of dust. Here, the detection device for detecting the amount of dust during suction is provided with, for example, a light emitting element and a light receiving element at opposite positions across a dust passage, and the output value of the light receiving element is changed according to the amount of dust passing. This is based on the use of fluctuation.

[0003]

However, the vacuum cleaner provided with the above-mentioned dust detection device is limited to a so-called high-grade vacuum cleaner. Therefore, if a general-purpose type vacuum cleaner is used at present, it is inconvenient to add a dust detection device to it even if one wants it. It is uneconomical to buy a new one.

In such a case, it is convenient if there is a dust sensor unit that can be easily attached to a hand-held vacuum cleaner, and a dust detection device can be freely added as an optional equipment when a general-purpose vacuum cleaner is sold. If possible, it is easy to respond to user demand. However, a simple vacuum cleaner
The problem is how to get power when it comes to wearing
Becomes Built-in battery in dust sensor unit
In addition, there is a problem that replacement is required depending on the battery life. The present invention has been made in view of these points, and a garbage sensor unit that can be easily attached to a general-purpose vacuum cleaner on hand without replacing batteries , and a general-purpose type vacuum cleaner. An object of the present invention is to provide a dust sensor unit that can be added as an optional device to a vacuum cleaner.

[0005]

In order to achieve the above object, a dust sensor unit according to the present invention includes a dust amount detecting unit for detecting an amount of dust sucked by a vacuum cleaner, and a dust amount detecting unit for detecting the amount of dust. A display unit that operates according to the output of the vacuum cleaner and displays the amount of dust being sucked, and a windmill that uses the suction power of the vacuum cleaner
A power generator configured to supply a power supply voltage to the display unit and the dust amount detection unit. The dust amount detection unit, the display unit, and the power supply unit are integrated into a vacuum cleaner. It can be mounted freely.

[0006]

In this dust sensor unit, the dust amount detection unit, the display unit, and the power supply unit are integrated, and only this dust sensor unit operates as a circuit for displaying the amount of dust passing therethrough. Since the dust sensor unit can be freely attached to a vacuum cleaner, for example, the dust sensor unit can be newly attached to an existing vacuum cleaner, or can be added as an optional device to a newly-sold vacuum cleaner. . Also,
Replace the battery because the power supply voltage is obtained by the generator using the suction force
No need to do.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to embodiments. FIG. 1 is a circuit block diagram of a dust sensor unit according to an embodiment of the present invention. This device includes a power supply unit 1, a light emitting element 2 for emitting inspection light, and a light receiving element 3 for receiving inspection light from the light emitting element 2.
And an amplifier 4 for amplifying the output voltage of the light receiving element 3 and a display 5 for receiving the output of the amplifier 4 and displaying the amount of dust passing therethrough.

The power supply section 1 does not receive AC power from the cleaner body via electric wires or the like, but is constituted by a power supply that generates a DC voltage by itself. More specifically, by using the wind power generator to turn the windmill using the suction force of the vacuum cleaner
I have.

The light-emitting element 2 and the light-receiving element 3 are installed at opposing positions in the dust passage, and when the vacuum cleaner sucks the dust, the light-receiving element 3 reduces the amount of light received according to the amount of the dust. It has become. When the amount of light received by the light receiving element 3 changes in this manner, the output voltage of the light receiving element 3 also changes in accordance with the change in the amount of received light. However, the amplifier 4 controls only the amount of change (AC component) of the light receiving element 3. The signal is amplified and supplied to the display 5 with a voltage corresponding to the amplitude of the AC component.

The display 5 is provided with a plurality of LEDs and liquid crystals, and displays the presence or absence of dust and the amount of dust based on these lighting locations. Alternatively, only one LED or liquid crystal may be provided, and the amount of dust may be displayed based on the blinking time of the LED or liquid crystal. In any case, the display 5 operates according to the input voltage from the amplifier 4 to display the amount of dust passing therethrough.

FIG. 2 shows a dust sensor unit having the structure shown in FIG. 1 mounted on a general-purpose vacuum cleaner. This vacuum cleaner originally used the nozzle portion 6 and the hose portion 8 directly connected to each other, but shows an example in which the nozzle portion 6 and the hose portion 8 are connected via the dust sensor unit 7. I have. That is, the inner diameter and the outer diameter of the upper diameter of the dust sensor unit 7 and the opening of the hose section 8 and the inner diameter of the dust section of the dust sensor unit 7 and the opening of the nozzle section 6 are the same, and insertion connection is possible. (See FIG. 3).

The dust sensor unit 7 has a display 5 on the surface thereof, and a power supply 1, a light receiving element 2, a light emitting element 3, and an amplifier 4 on other parts. As described above, the dust sensor unit 7 has an opening diameter that can be freely attached to and detached from the nozzle portion 6 and the hose portion 8. Can be added, or it can be added as an optional equipment to a new vacuum cleaner.

In the case of FIGS. 2 and 3, the dust sensor unit 7 serves as a connecting member between the nozzle portion 6 and the hose portion 8, but the present invention is not limited to this. The circuit of FIG. 1 may be provided in the nozzle section 6 (see FIG. 4). In this case, it is possible to newly mounted a "nozzle portion provided with a dust sensor unit" _6-1 the cleaner that is currently being used, or alternatively, the "dust sensor unit as optional equipment in the new vacuum cleaner A provided nozzle section “ _6-1 ” can also be added.

[0014] Figure 6 is an illustration of the type of dust sensor unit 7 _-1 sandwiched hose portion 8. In the case of this dust sensor unit, and clamped dust sensor unit _7-1 to the hose portion 8, and detects the amount of dust passing through the hose 8, the two locations in the hose 8 void portions 8 _{- 1} is provided. Then, the gap portion 8 _-1, the inspection light from the dust sensor unit _7-1 is controlled so as to match the position of the light emitting element 2 and the light receiving element 3 in a state of being sandwiched, one side of the gap portion Propagates to the other space and is received by the light receiving element 3 (see FIG. 5). Incidentally, while no clamped the dust sensor unit _7-1 to the hose portion 8, the hose portion 8
It is necessary to close the void portion _28-1, it is necessary to sandwich the hose portion 8 in a different clamping members.

[0015]

As described above, in the dust sensor unit according to the present invention, the power supply unit, the dust amount detecting unit, and the display unit are integrated, and the dust passing amount can be displayed by itself. . In addition, because it can be freely attached to a vacuum cleaner, it generates electricity by turning a windmill using suction power as a circuit power supply.
Do not worry about replacing batteries because
In addition, it can be additionally provided to the vacuum cleaner on hand of each user, and can also be added as an optional equipment of a new vacuum cleaner.
