In addition, in order to achieve the second object, the second invention makes the hollow part of the bumper a tube made of thin-walled polyethylene, etc., and the holding part sandwiched between the end peripheral parts of the upper part and the lower part of the main part is made of a soft material. In order to further achieve the third object, the vacuum cleaner has a holding part made of vinyl chloride or the like, and the third invention provides a valve body on the inner side of the hollow part of the hole that communicates the hollow part of the bumper with the motor chamber. It was a vacuum cleaner equipped with a

Function As described above, the present invention provides the bumper with a hollow portion projecting from the outer periphery of the main body, and a holding portion held between the top and bottom of the main body, and this holding portion includes a hollow portion located on the side surface of the motor chamber. Since a hole is provided that communicates the hollow portion with the motor chamber, exhaust gas is sent from the motor chamber through the hole into the hollow portion of the bumper when the motor is operated. Therefore, exhaust pressure is generated in the hollow part of the bumper, improving cushioning properties, and the protruding shape of the bumper prevents damage to the main body in the event of a collision.

In addition, as a second invention, the hollow part of the bumper is made of a tube made of thin-walled polyethylene, etc., and the holding part is made of soft vinyl chloride, etc., which improves the smoothness of the surface of the hollow part of the bumper, and ensures that the holding part is located above and below the main body. It can be held between the

In addition, as a third invention, a valve body is provided on the inner surface of the hollow part of the hole, so it opens when the motor is running and applies exhaust pressure to the hollow part of the bumper, and closes when the motor is stopped to seal the exhaust air and provide cushioning. can be further improved.

Embodiment 1 A vacuum cleaner which is an embodiment of the present invention will be explained based on the drawings.

In Figures 1 to 4, 1 is above the main body, 2 is below the main body,
A bumper 3 made of a soft material is sandwiched between the peripheral edges of each end to form an integrated main body 4. This main body 4 is provided with a motor chamber 48 at the rear that houses a motor, etc., a dust collection chamber 4b in which a dust collection bag is attached in front of the motor chamber 48, and a lid body 5 that covers the upper opening of the dust collection chamber 4b. There is. The bumper 3 is made of a soft material such as soft vinyl chloride as shown in FIG. It is integrally constituted by the holding part 7 which is attached to the holding part 7. Reference numeral 8 denotes a hole, which is provided in the holding portion 6 and located on the side surface of the motor chamber 4a, so as to communicate the hollow portion 6 and the motor chamber 4a.

In the above configuration, the exhaust gas discharged from the motor 9 when the motor 9 is in operation is sent from the motor chamber 4a to the hollow part 6 of the bumper 3 through the hole 8. Therefore, by applying exhaust pressure to the hollow portion 6, cushioning properties can be improved.

As another example, as shown in FIG. 3, the hollow part 6 of the bumper 3 is made of a thin-walled polyethylene tube lO, and the holding part II is made of a material such as vinyl chloride and integrally constitutes the bumper 3, thereby forming a protruding shape. Since the surface side is made of thin-walled polyethylene tube lO, it has good lubricity even when it hits furniture, etc., and can prevent the bumper 3 from being scraped and adhering to the object it comes into contact with, and at the same time can further soften the impact force by sliding. . Further, the holding portion 11 made of a material such as vinyl chloride can securely hold the main body between the upper part 1 and the lower part 2.

In yet another embodiment, as shown in FIG. 4, a valve body 12 is provided on the inner surface of the hollow portion 6 of the hole 8. This valve body I
2 is opened by exhaust pressure from the motor chamber 4a when the motor is operating, applies exhaust pressure to the hollow part 6 of the bumper 3, and is closed when the motor is stopped to seal the exhaust air. Therefore, even when the motor is stopped, the cushioning properties of the bumper 3 can be further improved.

Effects of the Invention As described above, in the first aspect of the present invention, the bumper is provided with a hollow portion projecting from the outer periphery of the main body and a holding portion that is held between the upper and lower end peripheral portions of the main body. Since a hole is provided on the side surface of the motor chamber to communicate the hollow space described in nII with the motor chamber, it is possible to improve the cushioning properties of the bumper due to exhaust pressure. Therefore, even when the bumper hits furniture, walls, etc., the impact can be softened by the presence of the protruding hollow part, and can be softened not only by the elasticity of the material of the bumper but also by the cushioning properties of the bumper. Therefore, not only can furniture and the like be prevented from being scratched, but the main body itself can also be reliably protected.

In addition, as a second invention, if the hollow part of the bumper is made of a thin-walled polyethylene tube, the surface of the bumper will have good lubricity, and the impact when it hits furniture, walls, etc. can be dissipated, thereby preventing scratches. It is now possible to prevent the bumper from being scratched and sticking to furniture, etc.

Furthermore, as a third invention, by providing a valve body on the inner surface of the hollow part of the hole, by opening and closing this valve body, the same cushioning properties of the bumper as when the motor is stopped can be exhibited. Ta.
