In the following, a first embodiment of the present invention will be described with reference to FIGS. In the suction nozzle body 1 connected to the suction pipe of the vacuum cleaner, the linear portion of the suction port peripheral edge 3 having a substantially oval shape has a comb-like shape with a space between the brush pin 4 and the brush pin 4, and has a hard elasticity. A plurality of brush pins 4 made of a certain resin or metal are provided. The shape of the brush pin 4 is an elongated substantially conical shape.
The distance between the brush pin 4 and the brush pin 4 is approximately the same as or slightly shorter than the distance between the brush bristles of a commonly used hair brush, and is about 2.5 mm to 4.0 mm. Since there is a gap between the brush pin 4 and the brush pin 4, the suction air flows therethrough, so that hair, cotton scraps and the like are not easily entangled with the brush pin 4. The length of the brush pin 4 is a little longer than the length from the base of the hair brush generally used to the tip of the brush hair, and is about 20.0 mm to 22.0 mm.

  Hard brush hairs 5a made of resin are implanted in the remaining portion of the suction port periphery 3. The length from the root of the bristle 5a to the tip is the same as the length of the brush pin 4. In the suction nozzle body 1, the fitting port 6 is provided between the connection portion 11 connected to the suction pipe of the vacuum cleaner and the suction port 2.

A second embodiment of the present invention will be described with reference to FIG.
In the suction nozzle of the first embodiment, brush bristles 5b which are shorter than the length of the brush pins 4 and made of the same material as the brush bristles 5a are implanted between the brush pins 4 and the brush pins 4.

A third embodiment of the present invention will be described with reference to FIGS. 5, 6, and 7. FIG.
Hard brush bristles 5a made of resin are planted on the entire periphery 3 of the suction port. In the suction port 2, the support portion 7 is bridged in the longitudinal direction L of the suction port 2, parallel to the straight line portion of the suction port peripheral edge 3, and in the center in the short direction S of the suction port 2. The support portion 7 is provided with a plurality of brush pins 4 made of resin or metal having a hard elasticity with a space between the brush pins 4. The length of the brush pin 4 may be the same as or slightly longer than the length of the brush bristles 5a implanted in the entire suction port periphery 3.
The support portion 7 spanned in the longitudinal direction L of the suction port 2 in parallel with the straight line portion of the suction port peripheral edge 3 and in the center of the suction port 2 in the short direction S is the center of the suction port 2 in the short direction S. Instead, it may be provided at a position close to either one of the straight portions of the suction port periphery 3.

A fourth embodiment of the present invention will be described with reference to FIGS.
In the comb-shaped brush pin row 8, a convex portion 9 is provided on the opposite side of the brush pin 4, and as shown in FIG. 9, the straight portion of the suction port periphery 3 provided with the comb-shaped brush pin 4 in the first embodiment is cut out. A portion where the comb-like brush pin row 8 enters and a concave portion 10a into which the convex portion 9 is fitted are provided. In this way, the comb-shaped brush pin row 8 is made detachable.

A fifth embodiment of the present invention will be described with reference to FIGS.
As shown in FIG. 10, a part of the support portion 7 in the third embodiment is notched, and a concave portion 10 b into which the comb tooth-shaped brush pin row 8 enters and the convex portion 9 is fitted is provided. In this way, the comb-shaped brush pin row 8 is made detachable. When the brush pins 4 are worn or damaged, the same performance as that of the original product is restored by replacing the comb-like brush pin rows 8.

  When the distance between the brush pins 4 is narrow, when the hair brush is cleaned with the suction nozzle of the present invention, the brush of the hair brush interferes with the brush pin 4 of the present invention. Since it cannot pass between hairs, cleaning is difficult. On the contrary, when the space | interval of the brush pin 4 and the brush pin 4 is too wide, the hair, cotton waste, etc. which have adhered to the hair brush become difficult to remove. Therefore, the distance between the brush pins 4 and the brush pins 4 is generally the same as or slightly shorter than the distance between the brush bristles of a hair brush that is generally used, and is about 2.5 mm to 4.0 mm.

  The shape of the brush pin 4 of the present invention is an elongated substantially conical shape. However, as shown in FIG. 11, the base portion of the brush pin is an elongated substantially quadrangular pyramid having a long rectangle in the short direction S at the suction port 2. It may be a thing. The brush pin having a substantially quadrangular pyramid shape can increase the strength against the force in the short direction S of the suction port.

  FIG. 12 shows the shape of the brush pin 4 when the comb-like brush pin 4 is positioned in the straight line portion of the suction port periphery 3 as in the first embodiment, the second embodiment, and the fourth embodiment of the present invention. As shown, the tip of the brush pin may be bent slightly in the short direction S inside the suction port 2. By doing so, when cleaning the hair brush, hair, cotton scraps and the like are easily caught on the tip of the brush pin, and cleaning becomes easy.

  In the first embodiment, the second embodiment, and the fourth embodiment of the present invention, the fitting port 6 is provided between the suction port 2 and the connection portion 11 connected to the suction pipe of the vacuum cleaner. In the third and fifth embodiments, the fitting port 6 is not provided in the suction port 2 only when the comb-like brush pin row 8 in the support portion 7 is located in the center in the short direction S of the suction port 2. . In this case, the left and right sides of the suction port 2 are symmetric with respect to the comb-tooth-shaped brush pin row 8, so that it is the same whether the suction nozzle body 1 is held with the right hand and the hair brush is cleaned with the left hand. It is because it can be cleaned.

  A large amount of hair loss is attached to pet brushes such as dogs and cats. Since the bristles 5a are more easily entangled than the brush pins 4, in the first, second and fourth aspects of the present invention, the brush bristles 5a and bristles 5b are not implanted, and the brush pins 4 are provided on the entire periphery of the suction port 3. May be.

When the first embodiment of the present invention is used, the connecting portion 11 is connected to the suction pipe of the vacuum cleaner, and the comb-like brush pin 4 is connected from the root of the hair of the hair brush to the tip as shown in FIG. Move and scrape hair, cotton lint, dandruff, etc., and suck with a vacuum cleaner. This operation can remove most hair, cotton scraps, dandruff, etc., but in order to remove the hair brush base, cotton scraps containing oils and fats adhering to the brush hair, etc. In this manner, the tip of the brush bristles 5a of the suction nozzle is scraped from the root of the brush bristles of the hair brush toward the tip, and scraps of cotton and the like adhering to the remaining oil and fat are scraped out and sucked with a vacuum cleaner.

Since there is a gap between the brush pin 4 and the brush pin 4, when the air is sucked with a vacuum cleaner, air flows in from there, and hair, cotton scraps and the like are not easily entangled with the brush pin 4. Even if the hair pin, brush bristles 5a, and bristles 5b are tangled with hair, cotton scraps, etc. after cleaning the hair brush, the suction switch of the vacuum cleaner is turned on and the brush pin 4, brush bristles 5a, bristles 5b The remaining hair, cotton lint, etc. can be picked up with your fingertips and sucked into a vacuum cleaner.
The suction nozzle of the present invention can be used not only for cleaning hair brushes but also for cleaning pet brushes such as dogs and cats.
