DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a smoke alarm with easily replaceable batteries and a replacement rod.

[0034] Reference Figure 1 and Figure 2A smoke alarm with easily replaceable batteries comprises a smoke alarm body 1 and a battery compartment 2. A battery accommodating chamber 11 is provided at one end of the smoke alarm body 1. The battery compartment 2 can be detachably connected to the battery accommodating chamber 11. A plug is arranged in the battery compartment 2. A jack is arranged at the bottom of the battery accommodating chamber 11. A magnetic connecting device 3 is fixedly connected to one end of the battery compartment 2 away from the smoke alarm body 1. A magnetic material is arranged at one end of the magnetic connecting device 3 away from the smoke alarm body 1.

[0035] When the smoke alarm is working, the battery compartment 2 is placed in the battery receiving cavity 11, and the battery compartment 2 is electrically connected to the smoke alarm body 1 by inserting the plug into the socket, so that the smoke alarm body 1 can work normally. When the battery compartment 2 is removed from the smoke alarm body 1, a tool with magnetic material can be used to make the tool and the magnetic material on the magnetic connection device 3 magnetically attracted, so that the battery compartment 2 is magnetically attracted to the tool, thereby driving the battery compartment 2 to move, so that the battery compartment 2 is removed from the smoke alarm body 1. The battery in the removed battery compartment 2 can be taken out and replaced with a new battery, and then the battery compartment 2 is driven by the tool so that the battery compartment 2 is inserted into the battery receiving cavity 11, so that the plug is inserted into the socket, and the replacement of the smoke alarm battery is completed. The entire replacement process can be completed on the ground, without the need for high-altitude operations, reducing the safety hazards during the replacement of the smoke alarm battery.

[0036] Reference Figure 2 and Figure 3 The battery receiving chamber 11 has a wall with a snap-in slot 111, which is preferably two symmetrically distributed snap-in slots 111 or four symmetrically distributed snap-in slots 111. The side wall of the battery compartment 2 facing the snap-in slot 111 is provided with an elastic card 4, which can be snapped into the snap-in slot 111.

[0037] After the battery compartment 2 enters the battery accommodating cavity 11, the elastic card 4 can be compressed by the cavity wall of the battery accommodating cavity 11. When the battery compartment 2 continues to move toward the bottom of the battery accommodating cavity 11 until the elastic card 4 enters the snap-in groove 111, the elastic card 4 enters the snap-in groove 111, thereby snapping into the groove wall of the snap-in groove 111, and then snapping the battery compartment 2 into the battery accommodating cavity 11, thereby realizing the assembly of the battery compartment 2 and the smoke alarm body 1.

[0038] Reference Figure 2 and Figure 3 A click piece 12 is arranged inside the card slot 111 . The click piece 12 is arranged in the middle of the card slot 111 , and the elastic card 4 can abut against the click piece 12 .

[0039] After the elastic card 4 enters the clamping slot 111, the elastic card 4 returns to its original shape under the action of its own elastic force, thereby hitting the clicker 12 in the clamping slot 111, causing the clicker 12 to make a sound, thereby reminding the staff who replaces the battery that the battery compartment 2 has been installed, which facilitates the staff who replaces the battery to replace the battery. The clicker 12 arranged in the middle of the clamping slot 111 can make a part of the sound generated by the clicker 12 echo in the cavity of the clamping slot 111 away from the elastic card 4 after the elastic card 4 hits the clicker 12, so that the staff who replaces the battery can more easily hear the sound of the clicker 12.

[0040] Reference Figure 1 and Figure 2 The battery accommodating cavity 11 is connected to the clicker 12 and the cavity wall at one end away from the cavity opening of the battery accommodating cavity 11 is arranged inclined toward the direction close to the battery compartment 2.

[0041] The inclined wall of the battery accommodating cavity 11 enables the battery compartment 2 to continue to be moved toward the smoke alarm body 1 after the elastic card 4 is engaged in the engaging groove 111 , so that the elastic card 4 approaches the battery compartment 2 under the action of the inclined wall of the battery accommodating cavity 11 .

[0042] Reference Figure 2 and Figure 3 The battery compartment 2 is provided with a compartment cover 21, one side of the compartment cover 21 is hinged to one side of the battery compartment 2, and the other side of the compartment cover 21 is snap-fitted to cover the battery compartment 2. Both sides of the compartment cover 21 are provided with limited slots 211, and the elastic card 4 can be snap-fitted into the limited slots 211.

[0043] The battery compartment cover 21 can reduce the probability of the battery in the battery compartment 2 falling out of the battery compartment 2. When the battery compartment 2 is driven by the tool and continues to move toward the smoke alarm body 1 from the state where the elastic card 4 is engaged in the engaging groove 111, the elastic card 4 can move closer to the compartment cover 21 under the action of the inclined wall of the battery receiving cavity 11, thereby entering the inside of the limiting engaging groove 211, so that when the battery compartment 2 moves away from the smoke alarm body 1, the elastic card 4 is no longer engaged in the engaging groove 111, so that the battery compartment 2 can be taken out of the battery receiving cavity 11, thereby facilitating the replacement of the battery of the smoke alarm.

[0044] Reference Figure 1 and Figure 3 The magnetic connection device 3 includes a connection plate 31, and a connection groove 311 is provided on the side of the connection plate 31 away from the smoke alarm. The shape of the connection groove 311 is preferably circular or square, and the bottom of the connection groove 311 is provided with magnetic material, which is preferably a magnet or an iron sheet.

[0045] When the tool is connected to the magnetic connection device 3, the end of the tool with the magnetic material is placed inside the connection groove 311, so that the magnetic material on the tool and the magnetic material in the magnetic connection device 3 are magnetically attracted together, thereby achieving the connection between the tool and the magnetic connection device 3.

[0046] Reference Figure 1 and Figure 4 A replacement rod 5 includes a rod body 51, one end of the rod body 51 is fixedly connected to a permanent magnet 52, and the end of the rod body 51 away from the permanent magnet 52 is provided with a handle 53, and the handle 53 is provided with anti-slip grooves 531. The replacement rod 5 is preferably a telescopic rod to facilitate the carrying of the replacement rod 5.

[0047] When using the replacement rod 5 , the end of the rod body 51 connected to the permanent magnet can be placed in the clamping groove 111 of the magnetic connection device 3 , so that the replacement rod 5 can be magnetically attracted to the magnetic connection device 3 , thereby driving the movement of the battery compartment 2 .

[0048] The implementation principle of the smoke alarm and the replacement rod 5 of the embodiment of the present application is as follows: when using the replacement rod 5 to replace the battery of the smoke alarm, the staff who replaces the battery stands on the ground, takes the replacement rod 5, and makes one end of the replacement rod 5 with the permanent magnet extend into the clamping groove 111 of the magnetic connection device 3, so that the replacement rod 5 and the magnetic connection device 3 are magnetically attracted together, and then continues to drive the replacement rod 5 to move in the direction of the smoke alarm body 1, so that the elastic card 4 on the side wall of the battery compartment 2 is clamped in the limiting clamping groove 211, and then drives the replacement rod 5 to move away from the smoke alarm, so that the battery compartment 2 is taken out of the battery accommodating cavity 11, so as to take out the battery compartment 2. The elastic card 4 is taken out from the limiting clamping groove 211, and the compartment cover 21 is opened to replace the battery in the battery compartment 2. After the replacement is completed, the battery compartment 2 is re-covered and placed on one end of the replacement rod 5 with the permanent magnet 52, so that the magnetic connection device 3 is magnetically attracted to the permanent magnet 52 of the replacement rod 5. The replacement rod 5 is driven to move toward the direction of the smoke alarm so that the battery compartment 2 enters the battery receiving cavity 11 until the sound of the clicker 12 is heard, and the replacement rod 5 is moved away from the smoke alarm body 1 so that the replacement rod 5 is separated from the magnetic connection device 3, and the battery of the smoke alarm is replaced. During the entire process of replacing the battery of the smoke alarm, the battery of the smoke alarm can be replaced without performing a high-altitude operation, thereby reducing the potential safety hazards during the process of replacing the battery of the smoke alarm.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
