[0002] In many electrical devices, such as smoke detectors, tactile switches are widely used to control the on / off state of circuits. However, a common problem with these switches is that the user must hold the button down continuously to maintain circuit continuity. This design, requiring a pressed-down state to maintain a circuit, is extremely inconvenient in practical applications, especially in scenarios involving prolonged operation or two-handed operation. Continuous pressing not only increases user fatigue but can also lead to operational errors, affecting the normal operation and safety of the equipment.

[0003] To address the aforementioned technical problems, this invention proposes an improved actuator for tactile switches. Summary of the Invention

By adding an actuator, the tactile switch can be conveniently and selectively arranged in an on or off state by moving the position of the actuator. This solves the problem that existing electrical devices including tactile switches must be kept pressed in order to achieve a circuit. Continuous pressing not only increases user fatigue but may also lead to operational errors, affecting the normal operation and safety of the equipment.

Detailed Implementation

[0016] The following is combined Figure 1-10 The present invention will be further described with reference to specific embodiments.

[0017] This invention uses a smoke detector as an example of an electrical device and a tactile switch, and an actuator for the tactile switch, to illustrate the working principle of an electrical device including a tactile switch according to this disclosure. It is worth noting that this is merely exemplary; the inventive concept according to this disclosure can be applied to any other electrical device including a tactile switch.

[0018] Figure 1 A schematic diagram of a smoke detector according to an embodiment of the present invention is shown. The smoke detector may include a main body, which may house a sensor, a power supply module, and an alarm module. The main body can be mounted to a suitable location on a building, such as a ceiling, wall, or supporting column, via a mounting plate. The main body may include a fixedly disposed housing 1, which may be formed, for example, in the form of a plate and adapted to cover the electrical components within the main body. Figure 4 The diagram shows the assembly structure of housing 1.

[0019] The smoke alarm according to an embodiment of the present invention, Figure 2 A three-dimensional structural schematic diagram of the actuator is shown. This invention provides an actuator for a tactile switch 3, which can be pressed to connect an electrical circuit in an electrical device and released to disconnect the electrical circuit. The actuator 2 includes: The cylindrical body 22 includes a first end and an opposite second end; The rotating plate 21 located at the top of the first end rotates the actuator 2 between a first position P1 and a second position P2. At the first position P1, the body 22 is adapted to contact the tactile switch 3 so that the tactile switch 3 is in an on state. At the second position P2, the body 22 is adapted to move away from the tactile switch 3 by a distance so that the tactile switch 3 is in an off state. The smoke detector also houses a tactile switch 3 (such as...) Figure 9-10 (As shown in the diagram). Actuator 2 can be mounted above the tactile switch and can move up and down relative to the tactile switch. When actuator 2 moves downward to press the tactile switch, the tactile switch is pressed, connecting the electrical circuit in the smoke alarm. When actuator 2 moves upward to release the tactile switch, the contact switch is released, disconnecting the electrical circuit.

[0020] like Figure 9-10 As shown, the actuator 2 is installed in the housing 1 and is movable between a first position P1 and a second position P2 to selectively arrange the tactile switch in an on or off state. In the first position P1, the actuator 2 presses the tactile switch so that the tactile switch is in the on state, and in the second position P2, the actuator 2 separates from the tactile switch so that the tactile switch is in the off state.

[0021] According to an embodiment of the smoke detector of the present invention, the tactile switch can be conveniently and selectively positioned in an on or off state by moving the position of the additionally provided actuator 2, without requiring the user to always press the trigger switch with one hand. This frees up the user's hand, which has significant practical advantages.

[0022] According to an embodiment of the smoke detector, between a first end and an opposite second end of the main body 22, there is a region 23 that is radially recessed from the main body 22 and forms the first position P1 and the second position P2 at different circumferential positions; According to an embodiment of the smoke detector of the present invention, the rotating plate 21 has a rectangular plate shape and an anti-slip groove is provided on its upper surface. The smoke alarm according to an embodiment of the present invention, Figure 3 A two-dimensional structural schematic diagram of the actuator is shown. The distance between the region of the first position P1 and the first end of the main body 22 is the same as the distance between the region of the second position P2 and the first end of the main body 22. Compared to the region of the first position P1 which is further from the second end of the body 22, the region of the second position P2 is closer to the second end of the body 22; thus, a height difference can be provided by the above structure, which may correspond, for example, to the movement stroke used to trigger the tactile switch action.

[0023] According to an embodiment of the smoke detector of the present invention, the actuator 2 is installed in a housing 1, the housing 1 including an opening 41 extending in the pressing direction, wherein the actuator 2 is rotatably installed in the opening 41 in an embedded manner; The tactile switch 3 is located at the bottom of the opening 41 and can automatically reset after the pressing action is canceled. According to an embodiment of the smoke alarm, the actuator 2 further includes a positioning portion 24 that protrudes radially outward from the body 22 at the second end, the positioning portion 24 providing positioning of the actuator 2 in the pressing direction; A positioning groove 42 is provided on the housing 1 radially outward from the opening 41, extending in the pressing direction. The positioning groove 42 is matched with the positioning part 24. The opening 41 is provided with a claw 43, wherein at the first position P1, the claw 43 forms a self-locking state with the first position P1 region of the actuator 2; at the second position P2, the claw 43 forms a non-self-locking state with the second position P2 region. Figure 5 A schematic diagram of the actuator located at position P1 is shown; Figure 6 A schematic diagram of the self-locking structure with the actuator at position P1 is shown; Figure 7 A schematic diagram of the actuator located at position P2 is shown; Figure 8 A schematic diagram of a non-self-locking structure with the actuator located at position P2 is shown; At the second end near the body 22, an inclined section of the moving track of the claw 43 is provided between the region of the first position P1 and the region of the second position P2. This inclined section allows for smoothness during the movement of each device during changes in height difference, which may correspond, for example, to a moving stroke used to trigger a tactile switch. In some embodiments, the inclined section may be formed as a smooth transition.

[0024] According to an embodiment of the smoke alarm, the present invention also provides an electrical device comprising: Casing 1; The tactile switch 3 can be pressed to connect the electrical circuit in the electrical device and released to disconnect the electrical circuit. And actuator 2, which is an actuator for a tactile switch as described above.

[0025] It is worth noting that the above description is merely exemplary to facilitate understanding of the inventive concept according to this disclosure. In other embodiments, the above arrangement may be reversed. For example, in other embodiments, the tactile switch may correspond to the off position at the first position P1, and to the contact position at the second position P2.
