サイド吸込口を有するものである。[Field of Industrial Application] The present invention relates to a suction port for a vacuum cleaner, and particularly to a suction port for a high-performance vacuum cleaner that is suitable for cleaning floors and can determine whether it is operated or not. It is something. [Prior art] Conventional techniques include Utility Model Application No. 21560 of 1972 and Utility Model Application No. 5 of
1. As shown in No. 22860, there is one in which brushes are installed before and after the suction port. Further, in each example, both sides (longitudinal direction) of the suction port are downwardly slanted, and the side suction ports are provided so that dust in the wall gap can be easily sucked in. These brushes use relatively stiff brushes and cannot be expected to be very effective in wiping floors. In particular, in the case of Utility Model Application Publication No. 51-22860, the brushes are sparsely installed and have almost no wiping effect. In addition, during normal operation (moving the suction mouth back and forth), pressure fluctuations within the suction mouth are unlikely to occur, and the vacuum cleaner itself uses a pressure sensor to detect pressure fluctuations within the suction mouth, and the user operates the suction mouth. The problem is that when trying to judge whether or not there is a problem, the output of pressure fluctuation is too small, making it difficult to make an accurate judgment. [Problems to be Solved by the Invention] An object of the present invention is to eliminate the above-mentioned drawbacks, to have a wiping effect on the floor surface, and to prevent pressure fluctuations in the suction port from easily occurring due to user operations, so that the vacuum cleaner body can The purpose is to be able to detect the output of this pressure fluctuation. ram) The suction port of the present invention has densely flocked bristles at the front and rear of the suction, divides either the front or rear brushes, and arranges a flexible pressure control plate between the brushes. A notch is provided at the tip of this pressure control plate, and the height is set to be equal to or higher than the height of the brush, and both sides of the suction port (in the longitudinal direction of the suction port)
It has a lowered side suction port to better suck in dust from the wall gaps.

ことから、床面への拭き効果が期待できるものである。In the suction port of the present invention, the brushes are densely flocked, so that when the suction port comes into contact with the floor surface, most of the suction flow will flow from other than the brush arrangement portion. That is, the suction flow flows into the suction hole from the side suction ports on both sides and the notch of the pressure control plate. Here, the height of the pressure control plate is set equal to or higher than the height of the brush, so every time the user operates the suction port (moves it back and forth), the pressure control plate moves the tip in the opposite direction to the direction of movement. The direction of this deformation changes each time the direction of operation of the suction port changes back and forth, which causes pressure fluctuations, and a pressure sensor installed in the vacuum cleaner body detects when the user operates the suction port. This allows control such as increasing the suction force when it is being operated and decreasing the suction force when it is not being operated. Additionally, since the brushes are densely flocked, they can be expected to have a wiping effect on the floor.

Figure 1 is a longitudinal sectional view of the suction port of the vacuum cleaner, Figure 2 is a plan view as seen from direction P in Figure 1, Figure 3 is an enlarged sectional view of the pressure control plate, and the fourth view is the same. It is a front view. The suction body 1 is provided with an upper case 2 on the upper side, a lower case 3 on the lower side, that is, the side facing the floor surface, and a bumper 4 for shock absorption with the wall surface on the outer periphery of the upper case 2 and the lower case 3. The extension pipe C (not shown) is connected to the extension pipe C (not shown), and the bent joint 5 serves as a passage for the sucked dust. Lower case 3 has a brush (large) with densely flocked brushes on the side facing the floor.
6 is arranged horizontally on the rear side of the suction port 9, and brushes (small) 7a, 7b are arranged on both sides of the front side, and brushes (small) 7a,
A pressure control plate 8 is arranged between 7b. This pressure control plate 8 is made of a flexible member such as rubber, and has a base 1
0 is fixed to the lower case 3, so the hardness is high and the flexible part 1
1 is made of a material with low hardness so that it can be bent back and forth due to changes in the suction air volume and operation of the suction port (back and forth movement), and the flexible part 11 has a notch 12, which is comparable to the size of a grain of rice. In addition to being able to suck in even large amounts of dust, the notch allows the flexible portion 11 to bend more easily and change the suction air volume. )1) There are side suction ports 12a and 12b in the part sandwiched by 7a and 7b, which are designed to suck in dust from the wall gap.The bumper 4 is located between the upper case 2 and the lower case 3.
is fitted and fixed with four screws 13. In the suction body configured as described above, when cleaning, the suction body 1 is placed on the floor and the passage through which the suction air flows is tightly closed by the brush (large) 6 and the brushes (small) 7a and 7b. The brush (large) 6 and the brush (
Since the brushes (small) 7a and 7b are planted closely, when the mouthpiece l touches the floor, the brushes (large) 6 and brushes (small) 7a, 7b
, most of the suction flow will flow from areas other than the side suction [D 12
a, 12b and the notch 12 of the pressure control plate 8. In addition, since the height of the pressure control plate 8 is set equal to or higher than that of the brushes (small) 7a and 7b, each time the user operates the suction body 1, the pressure control plate 8 The flexible portion 11 is bent and deformed in the direction opposite to the traveling direction. This deformation reverses direction with each stroke of operation, resulting in pressure fluctuations. By detecting this pressure fluctuation with a pressure sensor (not shown) installed in the vacuum cleaner body (not shown), it is possible to detect whether or not the user is operating the suction port. This has a big effect. In other words, it has the effect of reducing unnecessary noise only when it is operated and necessary, and when it is not inhaling. On the other hand, since the brushes (large) 6 and brushes (small) 7a and 7b are closely spaced, they come into close contact with the floor, and therefore have the effect of wiping the floor.

This has a great effect. In addition, the brushes are arranged in two rows on both sides of the suction port 2, and one side is arranged without being divided and planted closely together, so the brushes are in close contact with the floor surface, making it easier to use. It has a wiping effect.
