定になっていた。In any case, in the conventional suction port body of this type of vacuum cleaner, the position of the fixed body 9 of the vibrating body 8 is fixed with respect to the suction port body 4, and the positions of the front wheels 17 and the rear wheels 18 are fixed. It also has a structure fixed to the suction port main body 4,
Wheels '17. The height from the lower end of 18 to fixed body 9 was constant.

（発明が解決しようとする課題）
しかし、前記従来の構造では、接地体である車輪１７．
１８の下端から振動体８の固定体９までの高さが一定で
あったため、使い勝手や振動体８による塵埃の叩き出し
量が、じゅうたんあるいはたたみなどの被掃除面Ｐの種
類によって異なり、あらゆる被掃除面Ｐに適切には対応
できない問題があった。(Problems to be Solved by the Invention) However, in the conventional structure, the wheels 17.
Since the height from the lower end of the vibrating body 18 to the fixed body 9 of the vibrating body 8 was constant, the usability and the amount of dust thrown out by the vibrating body 8 differed depending on the type of surface P to be cleaned, such as a carpet or a folding surface. There was a problem that the cleaning surface P could not be dealt with appropriately.
それは、つぎのような理由による。すなわち、振動体８
の速度は本来その振動範囲のほぼ中心で最大になるから
、ここで振動体８が被掃除面Ｐの表面部に当たるとき、
叩き出し効果が最大になるのに対して、被掃除面Ｐの柔

が入り込むため、被掃除面Ｐに対する振動体８の高さが
低くなり、一方、たたみなどの比較的硬い被掃除面Ｐて
は、この被掃除面Ｐに対する振動体８の高さが高くなる
。This is due to the following reasons. That is, the vibrating body 8
Since the speed of is originally maximum at approximately the center of the vibration range, when the vibrating body 8 hits the surface part of the surface to be cleaned P,
While the knocking effect is maximized, the height of the vibrating body 8 relative to the surface to be cleaned P when the wheels 17 and 18 touch the surface P to be cleaned differs depending on the flexibility of the surface P to be cleaned. This is for the sake of coming. For example, for a flexible surface P to be cleaned such as a carpet, wheels 16, 17 are attached to this surface P to be cleaned.
, the height of the vibrating body 8 relative to the surface P to be cleaned becomes low. On the other hand, when the surface P to be cleaned is relatively hard, such as a folded surface, the height of the vibrating body 8 relative to the surface P to be cleaned becomes high.
そのため、第１１図および第１２図に示す振動体８がよ

がやはり小さい。Therefore, in the case of the suction port body of a vacuum cleaner in which the vibrating body 8 is located higher up as shown in FIGS. 11 and 12, in the case of a flexible surface P to be cleaned, the vibrating body 8 is Although it is effective because it hits almost the center of its original vibration range, in the case of a relatively hard surface P to be cleaned, this surface P
Since the vibrating body 8 is in the latter half of the period after passing through the center of its original vibration range, the striking effect is reduced. On the other hand, in the suction port body of a vacuum cleaner in which the vibrating body 8 shown in FIG. 13 and FIG. In the case of the surface to be cleaned P, the vibrating body 8 hits the surface P before reaching the center of its original vibration range, and its responsiveness to the surface P to be cleaned is still small.

めて悪くなる。In addition, in the suction port body of the vacuum cleaner shown in FIGS. 13 and 14, if the surface P to be cleaned is flexible, if the user cleans while lifting the suction port body 4 slightly, the dust can be knocked out. Although it can be effective, it makes it extremely difficult to use.

くなるために、吸込力か弱くなってしまう問題もあった
。In addition, in the case of a highly flexible surface P to be cleaned such as a carpet, the suction port body of any of the vacuum cleaners described above is attracted to the suction chamber 5, and the running performance of the suction port body 4 is deteriorated. On the other hand, in the case of a relatively hard surface P to be cleaned, such as a folded surface, the distance between the surface P to be cleaned and the suction chamber 5 becomes large, resulting in a problem that the suction force becomes weak.

This elastic shaft installed between a pair of fixed bodies at the bottom of the suction port body vibrates, and the plurality of striking bodies held by this elastic shaft vibrate to remove dust from the surface to be cleaned, such as a carpet or folding door. Knock it out. The dust that is knocked out in this way is sucked into the suction chamber that opens below the suction port body,
It is led to the dust collection chamber of the vacuum cleaner body via a connecting pipe. At this time, depending on the type of surface to be cleaned, flexibility, etc., the surface to be cleaned can be moved by operating the operating body to move the grounding body or the front fixed body of the vibrating body up and down relative to the suction port body. It is advisable to adjust the height position of the front fixed body of the vibrating body relative to the height of the vibrating body. For example, in the case of a flexible surface to be cleaned such as a carpet in which the grounding body sinks, the fixed body of the vibrating body should be positioned higher relative to the surface to be cleaned. In the case of a relatively hard surface to be cleaned, it is preferable to lower the position of the fixed body of the vibrating body with respect to the surface to be cleaned. This allows the vibrating body to hit the surface to be cleaned at approximately the center of its original vibration range, regardless of the conditions of the surface to be cleaned, and dust is efficiently knocked out from the surface to be cleaned.
そして、請求項２の電気掃除機の吸込口体では、操作体

通される。Furthermore, in the suction port body of the vacuum cleaner according to claim 4, when the fixed body of the vibrating body is in a lowered position with respect to the suction port body, the shielding body prevents the vibration body from opening downwardly in the suction port body. On the other hand, when the fixed body is in the raised position with respect to the suction port main body, the vibrating body chamber and the suction chamber are communicated with each other.

強い吸込力が得られる。Therefore, even if the surface to be cleaned is a carpet that is likely to cause sticking, if the fixed body is raised relative to the suction port body, the vacuum level of the suction chamber will not rise too much and stickiness will be prevented. This prevents deterioration in the running performance of the suction port body, maintains the distance between the vibrating body and the surface to be cleaned, and provides an effective knock-out effect. On the other hand, when the surface to be cleaned is relatively hard and there is a certain distance between the surface to be cleaned and the suction chamber, the degree of vacuum in the suction chamber can be reduced by lowering the fixed body relative to the suction port body. Rise,
Strong suction power can be obtained.

叩き出し効果が得られる。Therefore, as the fixed body 42 of the vibrating body 51 is moved up and down together with the movable plate 41 with respect to the suction port main body 21,
The area of the air passage formed between the surface P to be cleaned and the lower opening of the suction chamber 25 or the vibrator chamber 26 of the suction port body 21 changes. If the movable plate 41 is raised, the suction chamber 25 and the vibrating body chamber 26 are communicated with each other. The degree of vacuum in the chamber 25 does not rise too much, and the suction chamber 25 is prevented from being sucked by the carpet L. Therefore, a decrease in the running performance of the suction port body 21 is prevented. Along with this,
Combined with the rise of the vibrating body 51 itself, the degree of vacuum is prevented from increasing excessively, and the distance between the surface to be cleaned P and the vibrating body 51 is maintained at an appropriate level, making dust removal more effective. You can get the effect of putting it out.

へ強力に塵埃を吸込むことができる。On the other hand, when the surface P to be cleaned is relatively hard and folded and there is a certain distance between the surface P to be cleaned and the lower surface of the suction port main body 21, it is possible to lower the movable plate 41 to prevent the shielding. By shielding the suction chamber 25 and the vibrating body chamber 26 from each other by the body 81, the degree of vacuum within the suction chamber 25 can be increased, a strong suction force can be obtained, and the suction chamber 25
It can strongly suck in dust.
こうして、前記第３実施例の構成によれば、柔軟性など

遊離させることができる。In the suction port body of the vacuum cleaner according to claim 1, at least one of the grounding body that is in the suction port body and is grounded to the surface to be cleaned, and the elastic shaft of the vibrating body or the fixed body that is stretched is suctioned. Since the opening is movable up and down relative to the main body, for example, in the case of a flexible surface to be cleaned such as a carpet in which the grounding body sinks, the fixed body of the vibrating body can be positioned higher relative to the surface to be cleaned. On the other hand, in the case of a relatively hard surface to be cleaned, such as a folded surface that the grounding body does not sink into, the position of the fixed body of the vibrating body with respect to the surface to be cleaned can be lowered to reduce flexibility. The vibrating body can be positioned at an appropriate height relative to the surface to be cleaned, and the vibrating body can effectively knock out and release dust from different surfaces to be cleaned.

とができ、塵埃を強力に吸込める。Furthermore, in the suction port body of the vacuum cleaner according to claim 4, when the fixed body is in the raised position with respect to the suction port body, the vibrating body chamber and the suction chamber are communicated with each other, and the fixed body is in the lowered position with respect to the suction port body. It is equipped with a shield that isolates the vibrating body chamber from the suction chamber when the cleaner is in the suction chamber, so if the surface to be cleaned is a carpet that tends to stick, the fixed body can be raised relative to the suction port body. By doing so, it is possible to prevent the degree of vacuum in the suction chamber from rising too high, prevent deterioration of the running performance of the suction port body due to suction, and maintain the distance between the vibrating body and the surface to be cleaned. On the other hand, if the surface to be cleaned is relatively hard and there is a certain distance between the surface to be cleaned and the suction chamber, it is possible to obtain a more effective knocking effect. On the other hand, if the fixed body is lowered, the degree of vacuum in the suction chamber can be increased, a strong suction force can be obtained, and dust can be strongly sucked in.
