Detailed Description

The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.

As shown in fig. 1-5, a home security smoke alarm device comprises: the device comprises a shell 110, a driving motor 120, a rotary disc 130, a connecting rod 140, a smoke alarm 150, a sliding block 160 and a sliding rail 170.

The housing 110 is a rectangular parallelepiped and has an accommodating space therein. The housing 110 includes 4 sidewalls, a front plate and a back plate (not shown); wherein, the panel and the back plate are arranged oppositely. The housing 110 is detachably mounted to an indoor ceiling or wall through a back plate (not shown). In order to save space, the housing 110 may be embedded in the wall. The panel of the housing 110 is provided with an opening 111, two opposite side walls perpendicular to the panel (the opening 111) are respectively provided with a slide rail 170, the two slide rails 170 are symmetrically arranged, and the axial directions of the two slide rails 170 are both perpendicular to the panel where the opening 111 is located.

The driving motor 120 is disposed in the accommodating cavity of the housing 110, the driving motor 120 is fixedly connected to one side wall of the housing 110, and an output shaft 121 of the driving motor 120 is perpendicular to the two guide rails 170; the output end of the output shaft 121 is coaxially and fixedly provided with a turntable 130, and the turntable 130 is parallel to the plane where the two slide rails 170 are located; wherein, the turntable 130 is connected with the power output shaft of the motor through a flat key or a spline.

In this embodiment, the method further includes: and a motor bracket 122 fixedly installed on an inner wall of the housing 110 for fixing the driving motor.

One end of the connecting rod 140 is hinged with the disc surface of the rotating disc 130; the other end is hinged to the smoke alarm 150. A sliding bracket 152 is fixedly connected to the end (the end far away from the probe 151) of the smoke alarm 150, and sliders 160 are respectively fixedly connected to the two ends of the sliding bracket 152. The sliding bracket 152 is parallel to a plane where the two sliding rails 170 are located, and an axial direction of the sliding bracket 152 is perpendicular to an axial direction of the sliding rails 170. The two sliding blocks 160 are correspondingly and matchingly connected to the two sliding rails 170, and can slide along the sliding rails 170 respectively. Wherein, the probe 151 of the smoke alarm 150 corresponds to the position of the opening 111; the probe 151 can be extended from the opening 111 or retracted into the housing 110.

In another embodiment, two ends of the sliding rail 170 are respectively provided with a limiting portion (not shown in the figure) to prevent the sliding block 160 from falling off from the sliding rail 170, so as to further improve the safety performance of the home security smoke alarm device.

In this embodiment, the probe 151 is cylindrical, and the opening 111 of the housing 110 is circular and is clearance-fitted to the side wall of the probe 151.

Preferably, the hinge 131 of the connecting rod 140 and the rotating disc 130 is close to the outer edge of the rotating disc 130; the hinge 153 of the smoke alarm 150 to the link 140 is located on the side of the smoke alarm 150 (upper side) near the turntable, and the interface 153 is near the sliding bracket 152; with the above arrangement, the distance that the probe 151 moves can be increased with the length of the link 140 fixed; equivalently, the length of the connecting rod 140 can be reduced as much as possible, so that the size of the shell 110 is reduced, and the space occupied by the household security smoke alarm device is further reduced. Since the smoke alarm 150 is equipped with a buzzer or a voice prompt device, sound holes 180 are respectively formed on the four side walls of the housing 110, so that the alarm sound is transmitted from the sound holes 180 to prevent the transmission of the alarm sound from being blocked due to the provision of the housing 110.

The utility model provides a house security protection smog alarm device's theory of operation does: when the driving motor 120 rotates, the rotating disc 130 rotates along with the rotating disc, so as to drive one end of the connecting rod 140 to move along with the rotating disc 130, and due to the limiting effect of the sliding rail 170, the other end of the connecting rod 140 can only reciprocate along the axial direction of the sliding rail 170, so as to drive the smoke alarm 150 to reciprocate along the axial direction of the sliding rail 170, so that the probe 151 of the smoke alarm 150 extends out of the housing from the opening 111 or retracts into the accommodating cavity of the housing 110.

When the smoke alarm 150 works, the probe 151 extends out of the shell under the driving of the driving motor 120 so as to obtain better smoke detection effect; when the smoke alarm 150 is not operating, the probe 151 can be housed in the case 110, and the probe 151 can be protected from dust, sunlight, and the like.

While the embodiments of the invention have been described above, it is not intended to be limited to the details shown, or described, but rather to cover all modifications, which would come within the scope of the appended claims, and all changes which come within the meaning and range of equivalency of the art are therefore intended to be embraced therein.
