For example, in the vacuum cleaner 2, when the operation start switch 26a is operated while the electric blower 18 is stopped, the electric blower 18 is first started in the strong operation mode, and then the operation start switch 26a is operated again. The operation mode of the electric blower 18 is changed to the medium operation mode, and when the operation start switch 26a is operated three times, the operation mode of the electric blower 18 is changed to the weak operation mode, and so on. The strong operation mode, the medium operation mode, and the weak operation mode are a plurality of preset operation modes. The input value for the electric blower 18 is the largest in the strong operation mode and the smallest in the weak operation mode. The started electric blower 18 sucks air from the dust separation / dust collection unit 19 and makes the inside of the dust separation / dust collection unit 19 a negative pressure.

The negative pressure in the dust separation / dust collecting unit 19 sequentially passes through the main body connection port 23, the extension pipe 15, and the suction port body 16 and acts on the suction port 27. The vacuum cleaner 2 cleans the surface to be cleaned by sucking dust on the surface to be cleaned together with air by the negative pressure acting on the suction port 27. The dust separation / dust collecting unit 19 separates and accumulates dust from the dust-containing air sucked into the vacuum cleaner 2, while sending the air separated from the dust-containing air to the electric blower 18.

Further, the terminal connection restricting unit 73 includes a closing elastic member 77 that moves the terminal connection restricting unit 73 and closes the through hole 71 when the secondary battery 13 is removed from the battery mounting unit 25. The closing elastic member 77 stores energy by the movement of the terminal connection regulating portion 73 that opens the through hole 71 in conjunction with the movement of the secondary battery 13, and consumes this energy to close the through hole 71.

The terminal connection restricting unit 73 is not limited to the one that moves integrally with the operating piece 76. The terminal connection restricting unit 73 may be a known mechanism such as a link mechanism or a cam mechanism, and may include a mechanism that converts the movement of the secondary battery 13 into the opening and closing of the through hole 71.

The removal control unit 75 is, for example, a removal control port 83 provided on the flange portion 82 integrated with the secondary battery 13. The removal restriction port 83 overlaps with the through hole 71 of the battery mounting portion 25 in a state where the secondary battery 13 is mounted at the regular position of the battery mounting portion 25, and allows the power supply terminal 53 to reach the through hole 71.

Further, the removal restriction port 83 hinders the movement of the secondary battery 13 mounted on the battery mounting portion 25 with the power supply terminal 53 connected to the power receiving terminal 51, so that the secondary battery 13 is removed from the battery mounting portion 25. Regulate being removed. Specifically, the removal control unit 75 is a mechanism for mechanically and detachably holding the secondary battery 13 to the battery mounting unit 25, for example, in a state where the shoe and the rail are meshed with each other. It restricts the rail from moving in the direction of coming out of the shoe of the battery mounting portion 25.

The removal control port 83 is not limited to the removal control port 83 provided on the flange portion 82. The removal control port 83 mechanically contacts the power supply terminal 53 connected to the power receiving terminal 51, such as the notch provided in the flange portion 82, the edge of the flange portion 82, and the side wall of the case of the secondary battery 13. Any part may be used as long as it prevents the removal of the secondary battery 13.

You may have it. The connection release mechanism is different from the removal regulation unit 75 that regulates the removal of the secondary battery 13 when the power supply path 47 is connected to the power receiving terminal 51, and is linked to the removal of the secondary battery 13 with the power receiving terminal 51. The connection with the power supply path 47 is released.

For example, when the terminal connection restricting unit 73 closes the through hole 71, the connection disconnecting mechanism consumes the energy of the closing elastic member 77 and pushes the power supply path 47 out of the power receiving terminal 51. In this case, the connection disconnecting mechanism is composed of a known mechanism such as a link mechanism or a cam mechanism that converts the energy of the closing elastic member 77 into a force that pushes the power supply path 47 from the power receiving terminal 51. Further, the connection release mechanism pushes the power supply path 47 from the power receiving terminal 51 by the force applied to the operation unit 62, for example, when the lock mechanism 61 is released. In this case, the connection disconnecting mechanism is composed of a known mechanism such as a link mechanism or a cam mechanism that converts a force applied to the operation unit 62 into a force for pushing the power supply path 47 from the power receiving terminal 51.

Further, the connection disconnecting mechanism may have a hole (mouth) in the flange portion provided in the secondary battery 13, for example. In this case, it is preferable that the through hole 71 of the vacuum cleaner main body 12 is opened in the direction of moving when the secondary battery 13 is attached to and detached from the battery mounting portion 25. The hole of the secondary battery 13 overlaps with the through hole 71 when the secondary battery 13 is attached to the battery mounting portion 25, so that the power supply terminal 53 can be connected to the power receiving terminal 51, while the secondary battery 13 is mounted with the battery. When it is removed from the unit 25, the power supply terminal 53 is pulled out from the power receiving terminal 51 by moving the secondary battery 13.

The charging device 3 is also a storage stand for the vacuum cleaner main body 12. Then, the charging device 3 regulates that the secondary battery 13 is removed from the vacuum cleaner main body 12 when the charging device 3 electric vacuum cleaner 2 is attached and the power supply path 47 can supply power to the secondary battery 13.

Inhibit. The second removal control unit 85 hides the operation unit 62 of the lock mechanism 61 and hinders the operation regardless of whether the power supply path 47 is connected to the power receiving terminal 51 of the vacuum cleaner main body 12 or not.

The second removal control unit 85 is a part of the side wall portion 43 of the charging device 3 and hinders the movement of the lever 66 of the lock mechanism 61 in a state where the vacuum cleaner main body 12 is housed in the charging device 3. It may be.

Further, the second removal control unit 85 has a lock mechanism in a state where the vacuum cleaner main body 12 is housed in the charging device 3 by the surface to be cleaned on which the charging device 3 is installed and the wall surface on which the charging device 3 is installed. The operation unit 62 of 61 may be hidden to hinder the operation. In the floor-mounted charging device 3, the operation unit 62 of the lock mechanism 61 faces the surface to be cleaned so that the pushing operation cannot be performed, or the lever 66 of the lock mechanism 61 comes into contact with the surface to be cleaned and cannot move. The vacuum cleaner main body 12 is housed in the vicinity of the surface to be cleaned in a lying position (a posture in which the longitudinal direction of the vacuum cleaner main body 12 is turned sideways). In the wall-mounted charging device 3, the vacuum cleaner body 12 is used so that the operation unit 62 of the lock mechanism 61 faces the wall surface and cannot be pushed in, or the lever 66 of the lock mechanism 61 contacts the wall surface and cannot move. , It is stored in the vicinity of the wall surface in a standing posture (a posture in which the longitudinal direction of the vacuum cleaner main body 12 is turned up and down).
