A pointer 2, a pointer spring 3 that biases the pointer backward, a pointer lid 6 located behind the pointer 2 and having a through hole 4, a transparent cylindrical pointer barrel 6 that holds these, and a pointer barrel. A recess 1 in the front main body 1o that covers the dust collecting chamber 7 of the vacuum cleaner main body 9 from above.
1, a communication pipe 8 communicates with the dust collection chamber 7, and the pointer 2 is visible from the outside through a display window 13 provided on the cover plate 12.

できるものである。When the vacuum cleaner body 9 is used and dust accumulates in the dust collection bag 14, the pressure inside the dust collection chamber 7 gradually decreases to atmospheric pressure, and when the pressure drops further below a predetermined pressure, the pointer 2 is affected. Due to the vacuum pressure generated, the pointer 2 moves toward the communication tube 8 against the spring biasing force of the pointer spring 3. At this time, the position of the pointer 2 that extends beyond the display window 13 changes, allowing the user to recognize when it is time to dispose of the dust.

た。Problem to be Solved by the Invention However, in the above-mentioned display device 1, when the pointer 2 is even slightly displaced toward the communication pipe 8, the atmosphere flows through the through hole 4 into the dust collection chamber T.
As a result, the suction force from the suction port of the main body of the vacuum cleaner decreases. Therefore, it is necessary to set the displacement start pressure of the pointer 2 so that the pointer 2 is displaced when the dust collection bag 14 is almost full, and the pointer 2 is displaced in proportion to the amount of accumulated dust. It had the disadvantage that it did not. In particular, if the dust is mainly fibrous, the pressure inside the dust collection chamber T will not drop below the predetermined pressure even if the dust collection bag 14 is full, and the pointer 2 will not displace, so the dust will continue to be collected. The dust bag 14 burst, which also caused the problem of dust accumulating inside the hose connected to the main body 9.

である。Effect The first means works by blocking the vacuum pressure part on the dust collection chamber side from the atmospheric pressure part with the valve body, so even if the pointer is displaced in accordance with the displacement of the valve body, air leakage or suction will not occur. No force loss occurs,
Therefore, the displacement start pressure of the valve body can be made closer to atmospheric pressure than in the past, and the pointer can be displaced approximately in proportion to the amount of accumulated dust.

針弁３６とで構成されている。The dust collection amount display device 29 includes a transparent pointer tube 30, a green pointer A31 and a red pointer B32 that slide together in the pointer tube 3o, and a communication device that connects the dust collection chamber 23 and the pointer tube 3o. A pointer spring 34 is disposed between the tube 33, the communicating tube 33 and the pointer A31 and biases the pointer A31 and pointer B32 in the direction opposite to the direction of the communicating tube 33, and the pointer B32 is held between the pointer tube 30 and the pointer cover 35. It is comprised of a pointer valve 36 that airtightly isolates the side from the pointer lid 36 side.
指針筒３ｏの指針蓋３６取着側内部には、二重筒状に内
壁３７が形成され、内壁３７の連通管３３側先端で、指
針Ｂ３２の位置が規制されている。A double cylindrical inner wall 37 is formed inside the pointer barrel 3o on the side where the pointer cover 36 is attached, and the position of the pointer B32 is regulated at the tip of the inner wall 37 on the communication tube 33 side.
指針Ａ３１と指針Ｂ３２は互いに凹凸嵌合で結合されて

６が内周筒３９をおおい、指針蓋３５は指針弁３６を外
周側からおおっている。The pointer A31 and the pointer B32 are connected to each other by a concave-convex fit. The pointer B32 consists of a substantially cylindrical outer peripheral wall 38 and an inner peripheral tube 39, and includes a substantially cap-shaped pointer valve 3 made of a thin film having rubber elasticity.
6 covers the inner circumferential cylinder 39, and the pointer lid 35 covers the pointer valve 36 from the outer circumferential side.

する。The center of the pointer cover 36 is open and communicates with the outside of the main body 21, and one end of the communication tube 33 is connected to a through hole 4o provided on the lower surface of the recess 28.
The pointer valve 3
Atmospheric pressure acts on the pointer lid 36 side of No. 6, and vacuum pressure generated by the operation of the electric blower 24 acts on the pointer B32 side.

内で連通管３３側に変位させる。The pointer valve 36 receives the suction force toward the inside of the dust collecting chamber 23 due to the above-mentioned pressure difference acting on the inner wall 37 portion of the pointer barrel 3o and the spring biasing force of the pointer spring 34, and moves the pointer B32 toward the inner wall 37.

に少し変位する。Next, the operation and effects of the above configuration will be explained. When the vacuum cleaner body 21 is used and dust accumulates in the paper bag 22, the flow rate of air flowing into the electric blower 24 decreases, and the pressure in the dust collection chamber 23 gradually decreases to atmospheric pressure. When the amount of accumulated dust increases and this vacuum pressure becomes lower than a predetermined pressure, the pressure difference between the atmospheric pressure and the inner wall 37 of the pointer barrel 30 causes
The suction force that draws the pointer valve 36 toward the communication pipe 33 becomes greater than the spring biasing force of the pointer spring 34. At this time, pointer valve 3
6, the part of the pointer B32 that touches the inner cylinder 39 is the inner cylinder 3.
9 and the inner wall 37, the pointer A31° and the pointer B32 are inverted and deformed toward the communicating tube 33 side into a substantially U-shaped cross section, and at the same time, the pointer A31° and the pointer B32 are slightly displaced toward the communicating tube 33 side.
塵埃の蓄積が進むに連れて吸込力が大きくなると、指針
弁３６の略Ｕ字状の反転変形量が徐々に増大し、指針Ａ
３１、指針Ｂ３２を徐々に連通管３３側に移動させる。As the suction force increases as the accumulation of dust progresses, the approximately U-shaped reverse deformation of the pointer valve 36 gradually increases, and the pointer A
31. Gradually move the pointer B32 toward the communication tube 33.
この時、表示窓孔４２からは緑色の指針Ａ３１と赤色の

窓孔４２からは赤色の指針Ｂ３２のみが見え、使用者に
塵埃の廃棄時期を知らせ、紙袋２２を新しいものと交換
して強い吸い吸み状態で再使用し始めることとなる。At this time, the green pointer A31 and the red pointer B32 are visible from the display window hole 42 at the same time. When the amount of dust reaches a predetermined level, the displacement of the pointer A31 and pointer B32 becomes maximum, and only the red pointer B32 is visible from the display window hole 42, informing the user when it is time to discard the dust, and replacing the paper bag 22 with a new one. I will start using it again in a strong suction state by replacing it with.
ところで指針弁３６は、指針筒３ｏと指針蓋３６に挟持

範囲内に確実に変位させることができ、塵埃で一杯にな
った紙袋２２の継続使用による破裂等の不具合を防止で
きるものである。By the way, the pointer valve 36 is sandwiched between the pointer tube 3o and the pointer cover 36 and completely blocks off the vacuum pressure part on the pointer B32 side and the atmospheric pressure part on the pointer cover side.
Even if the pointer B32 is displaced, the dust collection chamber 2 is removed through the pointer tube 30.
Air does not flow into the chamber 3, and therefore, no wasteful reduction in suction force occurs. In addition, since the above-mentioned reduction in suction force does not occur, the spring biasing force of the pointer spring 34 in its initial state can be reduced, and the pointer valve 36 can be gradually displaced from a state of low vacuum pressure, allowing the inside of the display window hole 42 The displacement movement of the pointer A31 and pointer B32 can be made gradually in proportion to the decrease in pressure, allowing the user to recognize the amount of accumulated dust with higher precision than in the past. As a result, even when inhaling dust mainly composed of fibrous dust, the guideline A3
1. The pointer B32 can be reliably displaced within a displacement range that prompts the user to replace the paper bag 22, and problems such as bursting due to continued use of the paper bag 22 full of dust can be prevented.
さらに、指針弁３６は指針Ｂ３２に対して大気圧側に位

で支えることとなシ、指針弁３６の反転部分にはわずか
な力しか加わらず、指針弁３６の耐久性を劣化させるこ
とかない。Further, since the pointer valve 36 is located on the atmospheric pressure side with respect to the pointer B32, when the electric blower 24 is operating, the finger valve 36 and the end surface of the inner cylinder 39 of the pointer B32 on the pointer valve 36 side come into close contact. . Therefore, most of the suction force that acts on the pointer valve 36 due to the vacuum pressure difference and draws the pointer valve 36 toward the communication pipe 33 is transferred to the pointer valve 36 side end surface (rigid body portion) of the inner peripheral cylinder 39.
By supporting the pointer valve 36, only a slight force is applied to the inverted portion of the pointer valve 36, and the durability of the pointer valve 36 is not deteriorated.

This may cause sliding failure within the pointer A31.o or stain the inner surface of the pointer tube 3o. This prevents the pointer B32 from becoming difficult to see or causing damage to the pointer valve 36. Furthermore, guideline A31. Guideline B32. Since the displacement of the pointer valve 36 is determined only by the differential pressure acting within the inner wall 37 and the spring biasing force of the pointer spring 34, the spring load of the pointer spring 34 can be easily determined.

The operation in this case is the same as that of the first invention, but since the pointer valve 36 is formed integrally with the pointer cover 35, the number of parts is reduced by one, and the dust collection amount display device is improved. It can be provided at low cost.
また、指針弁３６を指針筒３ｏに挿入することによって
両者間の気密性を保てるため、指針蓋３５を使用する場
合に比べて、容易に気密性を得ることができる。Further, by inserting the pointer valve 36 into the pointer tube 3o, airtightness between the two can be maintained, so that airtightness can be easily achieved compared to the case where the pointer lid 35 is used.

A pointer that is displaced, a pointer spring that biases the pointer so that it starts to be displaced under a predetermined vacuum pressure, a pointer barrel that is a substantially transparent cylinder that has the pointer inside, and an airtight connection between the vacuum pressure section and the pointer barrel. By providing a communication pipe that connects the valve body and a pointer cover that airtightly attaches the valve body to the pointer tube, and by placing this valve body on the atmospheric pressure side with respect to the pointer, the pointer is displaced in accordance with the displacement of the valve body. Even if the valve body is moved, it does not cause air leakage, that is, a decrease in suction force, and therefore, the pressure at which the displacement of the valve body starts can be brought closer to atmospheric pressure than in the past, and the pointer can be displaced approximately in proportion to the amount of accumulated dust. , it is possible to maintain the durability of the pointer valve by bringing the pointer and most of the valve body into close contact with each other.
