Recently, carpets with particularly long piles have become popular in households, but it is extremely difficult to collect the dirt that accumulates at the base of the long piles with a regular vacuum cleaner nozzle, so a special Nozzles have also been developed. Figure 5
is a cross-sectional view of a vacuum cleaner developed for cleaning long-pile carpets, Figure 6 is a partially enlarged view, and Figure 17 is an enlarged view of a protrusion. In the figure, 1 is a vacuum cleaner, and 2 is a nozzle. , 3 is a protrusion with holes 3a, 4 is a rotating brush, 5 is a dust collection bag,
6 is the air flow, 7 is the carpet, and 7a is its pile. This vacuum cleaner has a nozzle 2 with a large number of protrusions 3 arranged orthogonally to the moving direction of the nozzle. When cleaning a carpet with a long pile 7a, the tips of the protrusions 3 are
The purpose is to reach the root of the bristles 7a and collect dirt and the like by suctioning them through the hole 3a.

して移動させながらの掃除は不可能である。[Problem to be Solved by the Invention] However, when cleaning is attempted using a nozzle equipped with the protrusion described above, the long hair of the carpet comes into contact with the protrusion 3 disposed on the nozzle 2, causing the nozzle 2 to move. This creates a large resistance to the movement of the nozzle 2, making it extremely difficult to move the nozzle 2, and it is virtually impossible to clean while pushing and moving the nozzle 2.

。[0005] Furthermore, even if the vacuum cleaner could be moved, it is possible to clean the deep part of the pile of the carpet, but it is difficult to collect the dirt that adheres to the surface of the carpet. Another nozzle must be used. In other words, it takes time and effort to replace the nozzle during cleaning.

成されている。[Means for Solving the Problems] In order to achieve the above object, the nozzle of a vacuum cleaner according to the present invention is provided with an opening on the bottom surface of the nozzle body, and also has an air suction hole, and by moving the nozzle, the opening is opened. It has a movable suction part configured to open and close. The opening is provided at the rear of the nozzle, and the suction section is formed with a plurality of suction bodies that protrude downward from the back surface of the nozzle and have a boat-shaped cross section. The opening is configured to open when moved, and closed when moved backward.

捕収することとなる。[Operation] Since the suction section is equipped with a suction body having a boat-shaped cross section and projecting below the nozzle, the suction section can effectively suction and collect dirt at the roots of the long piles of the carpet. The opening in the nozzle body also sucks up dirt from the carpet surface. Therefore, when the opening of the nozzle is closed by the suction section, the nozzle uses the suction section to suck in and collect dirt deep within the pile of the carpet, and when the suction section moves and opens the opening, the nozzle Dust is collected not only from the nozzle but also from the nozzle opening and from the surface of the carpet.

Furthermore, when the nozzle is moved backward, the suction body moves relatively forward and opens the opening. Therefore, when the nozzle is pushed or pulled back and forth during cleaning, the suction section automatically opens and closes the opening to collect dirt from the deep part of the pile of the carpet and from the surface.

いる。As shown in the figure, a slit-shaped opening 11 is formed at the bottom of the nozzle 10, and a suction section 1 is inserted into the opening 11.
Place 2. The suction section 12 is configured to move in the front-rear direction 16 with respect to the nozzle 10, and to open and close the opening 11 by this movement. The suction part 12 is a sliding plate 12a
A plurality of suction bodies 12b having a boat-shaped cross section are provided protrudingly from the suction body 12b, and each suction body 12b is provided with an air suction hole 13.

空気とともにごみを吸入捕収することとなる。When cleaning a carpet floor using a vacuum cleaner equipped with the nozzle 10 described above, when the nozzle 10 is moved forward, each suction body 12 of the suction unit 12 is moved forward, as shown in FIG.
b receives resistance from the carpet pile 5a, and the suction part 12
moves rearward relative to the nozzle 10, closing the opening 11 of the nozzle. Therefore, if the nozzle 10 is moved forward as it is, air will be sucked in from the floor only through the air suction hole 13 of the suction body 12b, and the air suction hole 13 will mainly suck and capture air and dirt from the deep part of the pile 5a of the carpet. The amount will be collected.

2 moves forward relative to the nozzle 10 and opens the opening 11 in the opposite direction when moving forward due to the resistance of the carpet pile 5a.
The nozzle 10 is connected to the opening 1 together with the air suction hole 13 of the suction section.
Air will also be inhaled from 1. In other words, not only the deep part of the carpet pile 7a but also the dirt and dust on the surface of the carpet 7 are collected. Note that since the air suction hole 13 has a greater resistance to air suction than the opening 11, the amount of air suctioned from the opening 11 is overwhelmingly larger than the amount of air suctioned from the air suction hole 13 of the suction body.

い。[0014] In this way, simply by moving the nozzle 10 back and forth, the opening 11 of the nozzle 10 automatically opens and closes, so that dirt and dust adhering not only to the deep part of the pile 7a of the carpet but also to the surface of the carpet can be removed. This means that the cleaning efficiency can be greatly improved. In the vacuum cleaner nozzle according to the present invention, the specifications of the suction part 12 are not limited to those in this embodiment, and the shape and number of the suction bodies 12b or the air suction holes 13 may be selected as appropriate. However, in order to use the suction body 12a for cleaning carpets, it is desirable that the suction body 12a has a boat-shaped cross section with tapered front and rear ends in the longitudinal direction. There is no need to limit the shape of the opening 11 to that of this embodiment.

という優れた効果を挙げることとなった。[Effects of the Invention] The vacuum cleaner nozzle according to the present invention has an opening on its bottom surface and a movable suction section configured to open and close the opening depending on the direction of movement of the nozzle. When cleaning a carpet floor, by simply moving the nozzle back and forth, it is possible to capture not only the deep layers of the carpet, but also the dirt and hair on the carpet surface, greatly improving the efficiency of cleaning the carpet floor. This resulted in excellent results.
