ものである。Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems consists of a substantially cap-shaped valve body that deforms due to the differential pressure between the vacuum pressure generated during operation of an electric blower and atmospheric pressure, and this valve body. A pointer is placed on the vacuum pressure side with respect to the valve body and is displaced in response to the deformation of the valve body, a pointer spring biases the pointer toward the atmospheric pressure side so that the pointer starts to be displaced under a predetermined vacuum pressure, and a pointer is placed inside the valve body. The amount of dust collected is increased by a pointer tube which is a substantially transparent cylindrical body, a communication tube that airtightly connects the vacuum pressure section and the pointer tube, and a pointer lid that covers the valve body from the atmospheric pressure side.
This action is such that the vacuum pressure part and the atmospheric pressure part are shut off by the valve body held between the pointer tube and the pointer lid, so even if the pointer is displaced in response to the deformation of the valve body, air leakage, that is, the suction force is reduced. Therefore, the deformation starting pressure of the valve body 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.

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, a suction force that draws the pointer valve 36 toward the communication pipe 33 side is generated due to the differential pressure between the atmospheric pressure and the inner wall 37 of the pointer tube 3°. becomes larger than the spring biasing force of the pointer spring 34. At this time, in the pointer valve 36, the part of the pointer B32 that touches the inner circumferential tube 39 is reversely deformed between the inner circumferential tube 39 and the inner wall 37 into a substantially U-shaped cross section toward the communicating tube 33, and at the same time, the pointer A31 and pointer B32 are It is slightly displaced toward the communication pipe 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８３２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. The pointer 832 is gradually moved toward the communication tube 33.

して強い吸い込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 exceeds a predetermined level, the displacement of the pointer A31 and pointer B32 reaches its maximum, and only the red pointer E32 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 replaced it with a new one and started using it again with strong suction.

を防止できるものである。By the way, the pointer valve 36 is sandwiched between the pointer tube 30 and the pointer cover 36 and completely blocks off the vacuum pressure section on the pointer B32 side and the atmospheric pressure section on the pointer cover 35 side.
1 or the pointer B32 is displaced, the air does not flow into the dust collection chamber 23 through the pointer barrel 3o, and therefore, no wasteful reduction in suction force occurs. In addition, since the above-described decrease in suction force does not occur, the spring biasing force of the pointer spring 34 in the initial state is reduced, and the pointer valve 34 is gradually moved from a state of low vacuum pressure.
6 can be deformed, and the pointer A within the display window hole 42
31 and pointer B82 gradually in proportion to the decrease in pressure, the user can recognize the amount of accumulated dust more accurately than in the past. As a result, even when dust mainly consisting of fibrous dust is inhaled, the pointer A31° and the pointer B32 can be reliably displaced within the range of 0.-' to prompt the user to replace the paper bag 22. C' It is possible to prevent problems such as bursting due to continued use of a full paper bag 22.

ととなる。By the way, the pointer valve 36 is sandwiched between the two parts by fitting the pointer cover 35 to the pointer tube 30, and at the same time obtains airtightness and cuts off the vacuum pressure side and the atmospheric pressure side, so that the dust collection amount display device 29 can be easily operated. It can be made into a unit component, and can be assembled separately from the assembly of the vacuum cleaner main body 21.
さらに指針蓋３６は指針弁３６を大気圧側よりおおって
いるため、ユニット部品として組み立てられた集塵量表
示装置２９を搬送する途中、薄膜の指針弁３６の損傷を
防止できるものである。Furthermore, since the pointer lid 36 covers the pointer valve 36 from the atmospheric pressure side, it is possible to prevent the thin-film pointer valve 36 from being damaged during transportation of the collected dust amount display device 29 assembled as a unit component.
