Embodiment approach 1

[0032] One embodiment of the present invention will be described.

[0033] (1-1. Overall configuration of ion generator 100)

[0034] figure 1 It is a perspective view of the ion generator (electric appliance) 100 of this embodiment, figure 2 is a cross-sectional view of the ion generator 100 .

[0035] Such as figure 1 and figure 2 As shown, the ion generator 100 is equipped with the adapter 20, and the main-body part 10 attached to the adapter 20 so that attachment and detachment are possible.

[0036] The adapter (attachment unit) 20 includes a plug (base plug) 21 to be attached to a socket (attachment site) installed on a ceiling, wall, floor, installation surface of various appliances, and the like. That is, a helical thread and a helical groove are formed at positions corresponding to each other in the plug 21 and the socket, and the ion generator 100 is attached to and detached from the socket by rotating the ion generator 100 .

[0037] And by attaching the plu...

Embodiment approach 2

[0104] Another embodiment of the present invention will be described. In addition, for convenience of explanation, the same symbols are attached to components having the same functions as those in Embodiment 1, and description thereof will be omitted.

[0105] In Embodiment 1, the configuration for performing the warning operation when the power supply to the main body unit 10 is interrupted has been described. On the other hand, in the present embodiment, a description will be given of a configuration in which a warning operation is performed when the main body portion 10 is rotated or moved.

[0106] Figure 8 It is a block diagram which shows the structure of the control system and the power supply system in the ion generator 100 of this embodiment.

[0107] Such as Figure 8 As shown, the ion generator 100 of this embodiment replaces Figure 5 The voltage detection part 81 in the ion generator 100 shown has the rotation detection part 86. As shown in FIG.

[0108] The...

Embodiment approach 3

[0117] Still another embodiment of the present invention will be described. In addition, for convenience of description, the same reference numerals are attached to components having the same functions as those in the above-mentioned embodiment, and description thereof will be omitted.

[0118] In Embodiment 1, the description has been given of the configuration in which the warning operation is performed when the power voltage to the main body 10 has dropped below a predetermined value. On the other hand, in the present embodiment, a description will be given of a configuration in which a warning operation is performed when the detection results of the human detection sensor 70 and the detection results of the supply voltage to the main body 10 satisfy predetermined conditions.

[0119] Figure 10 It is a block diagram which shows the structure of the control system and the power supply system in the ion generator 100 of this embodiment. As shown in this figure, in the ion ...

Abstract

Provided is an electric tool configured so that the improper removal of the electric tool is appropriately detected and a warning is issued. When removing a base plug (21) from a socket or removing abody unit (10) from an adapter (20), a circuit is formed in order to cause a switch (83) to switch a power supply path, which is from a battery (82) to a speaker (60), from a cutoff state to a conductive state so as to cause the speaker (60) to issue a warning.

Description

technical field [0001] The present invention relates to an electric appliance which is installed in a ceiling, a wall, a floor, a mounted portion provided in various devices, etc., and is provided with a warning unit which performs a predetermined warning operation to prevent theft. Background technique [0002] Conventionally, electrical appliances (for example, light bulbs) are known that are detachably attached to installation portions such as sockets and junction boxes attached to installation surfaces of ceilings, walls, floors, and various devices. [0003] In general, these electrical appliances are configured to be easily attached to and detached from the mounted portion for easy replacement, cleaning, and the like. [0004] However, in the case of a structure that can be easily attached to and detached from the mounted part, for example, when installed in a public facility used by an unspecified number of people such as a restaurant or a commercial facility, there i...
