Description
Technical Field
[0001] The present invention relates to the technical field of fire alarm technology, and in particular to a smart fire alarm device. Background Art
[0002] Smoke alarms are safety devices designed to detect smoke and sound an alarm. They are widely used in homes, offices, factories, shopping malls, and other places. They are designed to detect fires early, prompting people to take countermeasures, and reduce fire damage. Smoke alarms primarily detect smoke based on optical or ionization principles, exploiting the scattering of light. They contain a light source and a photosensor. Under normal circumstances, light from the light source travels in a straight line and does not strike the photosensor. When smoke enters the alarm, smoke particles scatter the light, allowing some of it to strike the photosensor, triggering the alarm circuit and sounding the alarm.
[0003] For example, the Chinese patent "CN114863632A, discloses a smoke alarm" includes a cylindrical shell, and a number of light source cabins are arranged in a circular array along the axis of the cylindrical shell. Ultraviolet emitting lamp beads are fixedly installed in the light source cabins. The smoke alarm cabin compresses the UV glue storage cabin space by rising and then squeezes the UV glue stored inside out of the installation groove. Reflectors are also flipped in the light source cabins. The reflectors refract the light source emitted by the ultraviolet emitting lamp beads in two directions, upward or downward. The annular shielding plate is provided with light-transmitting holes in a circular array along its axis, which are the same in number and correspond one to one to the light source cabins.
[0004] To ensure a secure installation, common smoke alarms on the market are generally fixed to the ceiling with expansion screws. This fixing method has obvious disadvantages: once installed, the alarm is difficult to remove, which means that in actual use, users cannot remove it regularly for inspection. Smoke alarms are prone to malfunctions during long-term operation, but due to the lack of effective detection methods, these malfunctions are often difficult to detect in time. Once a fire occurs, the alarm is very likely to fail, thus missing the best time for fire rescue and posing a serious threat to people's lives and property. Summary of the Invention
[0005] The present invention relates to an intelligent fire alarm device, which connects a smoke alarm to the bottom of a docking seat by rotating and clamping, making it easier to assemble and disassemble the smoke alarm. The smoke alarm can be regularly disassembled for inspection to avoid malfunction of the smoke alarm and ensure that the smoke alarm can work normally when a fire occurs.
[0006] According to a first aspect of the present invention, a smart fire alarm device is provided, which specifically includes: a top base, a docking seat, a smoke alarm, a rotating disk, a positioning pin, a time display and a fan; the top base is fixed to the ceiling, the bottom of the top base is fixedly connected to the docking seat, and the bottom of the docking seat is connected to the smoke alarm; the docking seat is internally connected to the rotating disk, and two positioning pins are installed inside the docking seat, the top of the positioning pin is in contact with the rotating disk, and the bottom of the positioning pin is connected to the smoke alarm; the bottom of the smoke alarm is fixedly installed with a time display; two fans are fixedly installed on the inside of the top base, and the smoke alarm is located between the two fans.
[0007] Furthermore, a card slot is provided around the bottom of the docking seat, and the card slot is L-shaped. A card block is provided around the top of the smoke alarm, and the card block is connected to the card slot. The smoke alarm is connected to the bottom of the docking seat by rotating the card connection, making it easier to disassemble and assemble the smoke alarm, so that the smoke alarm can be disassembled for inspection regularly.
[0008] Furthermore, vertical guide holes are symmetrically arranged inside the docking seat, a positioning groove is arranged around the top of the smoke alarm, the bottom of the vertical guide hole is connected to the positioning groove, the positioning pin slides through the vertical guide hole, and the bottom end of the positioning pin is inserted into the positioning groove.
[0009] Furthermore, the rotating disk is rotatably connected to the docking seat, a movable sliding hole is arranged around the outside of the docking seat, and a turning handle is arranged around the outside of the rotating disk. The turning handle is slidably connected to the movable sliding hole, and the rotation angle of the rotating disk is limited by the sliding cooperation between the turning handle and the movable sliding hole.
[0010] Furthermore, an arc-shaped boss is symmetrically provided on the bottom side of the rotating disk, and both ends of the arc-shaped boss are inclined. The top of the positioning pin is in sliding contact with the arc-shaped boss. A spring A is mounted on the outside of the positioning pin. The top of the spring A is in contact with the positioning pin, and the bottom of the spring A is in contact with the docking seat. The spring A has an elastic reset effect on the positioning pin. When the card block is rotated and connected to the innermost end of the card slot, the vertical guide hole and the positioning slot are in a connected state. The rotating disk is rotated, and the top of the positioning pin is in contact with the inclined surface of the arc-shaped boss, pushing the positioning pin to move downward. The spring A is forced to contract, so that the bottom end of the positioning pin is inserted into the positioning slot, thereby locking and fixing the smoke alarm.
[0011] Furthermore, the time display is composed of an outer shell, a digital ring, a damping pin and a spring B, and the outer shell is fixedly connected to the smoke alarm.
[0012] Furthermore, a time display port is provided on the outside of the outer shell, and a digital ring is rotatably connected to the outer shell, and the numbers on the digital ring are located in the time display port. After the smoke alarm is detected, the digital ring is rotated to combine the current date at the time display port so that the next detection operation can be carried out according to this date.
[0013] Furthermore, a transverse guide hole is provided inside the outer shell, and the damping pin is slidably connected in the transverse guide hole, and the end of the damping pin contacts the inner side of the digital ring. The spring B is sleeved on the outside of the damping pin, one end of the spring B contacts the damping pin, and the other end of the spring B contacts the outer shell. The damping pin is guided by the transverse guide hole, and the spring B has an elastic reset effect on the damping pin. After the rotation adjustment of the digital ring is completed, the end of the damping pin is affected by the thrust of the spring B and is in close contact with the inner wall of the digital ring, thereby increasing the rotation resistance of the digital ring and preventing the digital ring from rotating.
[0014] Furthermore, the two fans are located at opposite ends of the smoke alarm in a staggered manner, with the air outlet ends of the fans facing outward. The fans draw the air around the smoke alarm outward, so that the air below is replenished to the area around the smoke alarm, thereby promoting air circulation around the smoke alarm. In the event of a fire, the smoke alarm can sense the smoke generated by the fire more quickly and sound an alarm.
[0015] The present invention provides a smart fire alarm device, which has the following beneficial effects: When the smoke alarm is in use, the smoke alarm is connected to the bottom of the docking seat by a rotating clamping connection, which makes the smoke alarm easier to assemble and disassemble, so that the smoke alarm can be regularly disassembled for inspection, ensuring that the smoke alarm can work normally when a fire occurs; the rotating handle is slidably engaged with the movable sliding hole to limit the rotation angle of the rotating disk; and the spring A plays an elastic reset effect on the positioning pin; when the clamping block is rotated and clamped to the innermost end of the clamping slot, the vertical guide hole and the positioning slot are in a connected state, the rotating disk is rotated, the top end of the positioning pin contacts the inclined surface of the arc-shaped boss, pushing the positioning pin downward, the spring A is forced to contract, and the bottom end of the positioning pin is inserted into the positioning slot, locking and fixing the smoke alarm, ensuring the firmness of the installation of the smoke alarm; when the smoke alarm needs to be disassembled for regular inspection, the rotating disk is rotated in the opposite direction, and the positioning pin moves upward under the influence of the thrust of the spring A until it is reset, and the bottom end of the positioning pin is separated from the positioning slot, the positioning pin releases the lock of the smoke alarm, and the smoke alarm can be rotated in the opposite direction, and the smoke alarm can be disassembled for regular inspection.
[0016] In addition, after the smoke alarm is inspected, the digital ring is rotated to display the current date on the time display so that the next inspection can be performed based on this date. This effectively avoids the smoke alarm inspection interval being too long, which may cause the smoke alarm to malfunction in this interval and affect the normal alarm effect when a fire occurs. The damping pin is guided by the cross guide hole and elastically reset by spring B. After the digital ring is rotated and adjusted, the end of the damping pin is in close contact with the inner wall of the digital ring under the influence of the thrust of spring B, which increases the rotation resistance of the digital ring, prevents the digital ring from rotating on its own, and ensures the accuracy of the displayed date.
[0017] In addition, the fan draws the air around the smoke alarm outward, so that the air below is replenished to the area around the smoke alarm, promoting air circulation around the smoke alarm. In the event of a fire, the smoke alarm can sense the smoke generated by the fire more quickly and sound an alarm, reminding people to respond before the fire spreads, thereby ensuring the safety of life and property.
