[0030] Embodiment 1 Additional aspects and advantages of embodiments of the present invention will be given in part in the following description, become apparent in part from the following description, or be learned through the practice of the embodiments of the present invention. In combination with Figures 1 - 5 , an embodiment of the present invention provides a portable smoke-sensing fire detector alarm, comprising: A housing 1, a conductive component 2, an assembly component 3, a positioning component 4 and a pushing component 5. The conductive component 2 is fixedly connected to one side of the housing 1. The assembly component 3 is arranged on the same side as the conductive component 2 and is fixedly connected to the housing 1. The positioning component 4 is arranged below the housing 1 and is fixedly connected to the housing 1 by snap connection. The pushing component 5 is arranged below the positioning component 4 and is fixedly connected to the positioning component 4. Among them, The positioning component 4 includes a replacement table 401. A positioning groove 402 is formed on one side of the replacement table 401. On the other side of the replacement table 401, a placing table 403 and a storage frame 407 are respectively fixedly connected; The pushing component 5 includes a movable rod 503. The top of the movable rod 503 is fixedly connected to the bottom of the replacement table 401. A handheld rod 504 is fixedly sleeved on the bottom of the movable rod 503. A retaining ring 502 is fixedly connected to the top of the handheld rod 504, and the retaining ring 502 is movably sleeved on the movable rod 503. An extension rod 505 is fixedly connected to one side of the retaining ring 502. A connecting rod 506 is fixedly connected to the end of the extension rod 505 away from the retaining ring 502. A pushing block 507 is fixedly connected to the top of the connecting rod 506. The pushing block 507 is embedded between two supports of the placing table 403 and is slidably connected to the two supports. The pushing block 507 is a wedge-shaped structure, and its upper surface is inclined to the horizontal plane. A spring 501 is movably sleeved above the top of the movable rod 503 and above the retaining ring 502.

[0031] In a specific embodiment of the present invention, since the top of the handheld rod 504 is movably connected to the movable rod 503, and the top of the movable rod 503 is fixedly connected to the bottom of the replacement table 401, when the handheld rod 504 is pushed upward, the retaining ring 502 generates an upward pressure on the spring 501. The reaction force generated by the spring 501 is transmitted to the pushing block 507 through the handheld rod 504, the retaining ring 502 and the extension rod 505, so that the pushing block 507 is pushed upward. Since the pushing block 507 is embedded between two supports of the placing table 403 and the top of the pushing block 507 is an inclined surface, the battery 6 slides in the direction of the battery compartment 301 when it is acted on by the pushing block 507. With the application of the upward acting force, the new battery to be replaced abuts against the old battery in the battery compartment 301 and pushes the old battery in the battery compartment 301 until the two electrodes of the new battery to be replaced are electrically connected to the conductive elastic sheet 202. The replaced old battery falls into the storage frame 407 from the other side of the battery compartment 301 under the action of its own gravity, thereby realizing the replacement operation of the old and new batteries.

[0032] Specifically, a plurality of buckles 101 are fixedly connected to the top of the housing 1. The plurality of buckles 101 are distributed in an annular array around the center of the housing 1. An installation base 7 is arranged on the top of the housing 1, and a plurality of installation slots 701 are formed in the installation base 7. The installation slots 701 are fixedly connected to the buckles 101 in a snap-fit manner. When assembling the housing 1 and the installation base 7, first align the buckles 101 on the top of the housing 1 with the positions of the installation slots 701 on the installation base 7, and then push the housing 1 upward to make the buckles 101 fixedly connected to the installation slots 701 in a snap-fit manner.

[0033] Specifically, two installation slots 102 are formed in one side of the housing 1. The installation slots 102 are fixedly connected to the conductive component 2. The conductive component 2 includes a conductive block 201. One side of the conductive block 201 is fixedly connected to a conductive elastic piece 202, and the other side of the conductive block 201 is fixedly connected to an electrode post 203. The conductive block 201 is embedded in the inner wall of the installation slot 102 and fixedly connected to the installation slot 102. The electrode post 203 is disposed through the housing 1. By forming the installation slots 102 on one side of the housing 1, the two electrode posts 203 of the conductive component 2 penetrate into the interior of the housing 1, and thus are electrically connected to the PCB circuit board installed inside the housing 1.

[0034] Specifically, a PCB circuit board is installed inside the housing 1. The PCB circuit board is electrically connected to the two electrode posts 203. A smoke sensor, a buzzer and an LED lamp are integrated on the PCB circuit board. The smoke sensor is used to monitor the smoke particles in the air and feedback to the control chip through an electrical signal. The buzzer and the LED lamp are used to emit a buzzer sound and flash for alarm. When the smoke sensor monitors the smoke particles in the air, it feeds back to the control chip through an electrical signal, and then the control chip sends an alarm instruction to trigger the buzzer and the LED lamp.

[0035] Specifically, the assembly component 3 includes a battery compartment 301. One side of the battery compartment 301 is fixedly connected to one side of the housing 1, and the conductive elastic piece 202 is located inside the battery compartment 301. A battery 6 is fixedly connected to the inside of the battery compartment 301 in a snap-fit manner. The two electrodes of the battery 6 are respectively abutted against the two conductive elastic pieces 202. In a specific embodiment of the present invention, the battery 6 adopts a conventional 9V square dry battery. Since the two electrodes of the 9V square dry battery are located on the same side, rapid operation can be performed during battery replacement and the battery capacity requirement can be met. A baffle 302 is fixedly connected to the top of one side of the battery compartment 301. The baffle 302 abuts against the upper surface of the battery 1. By providing the battery compartment 301 to fix the battery 6, when installing and replacing the battery 6, the two electrodes of the battery 6 are respectively abutted against the two conductive elastic pieces 202. Since the conductive elastic piece 202 is in contact with the conductive block 201, and the conductive block 201 is in contact with the two electrode posts 203, the battery 6 supplies power to the PCB circuit board inside the housing 1.

[0036] Specifically, the placing platform 403 includes two L-shaped supports arranged in parallel. A stop bar 404 is fixedly connected to the top of one of the supports, and a metal elastic sheet 406 is fixedly connected to the top of the opposite support. Fixing columns 405 are fixedly connected to both ends of the metal elastic sheet 406, and the bottom of the fixing column 405 is fixedly connected to the support. A battery 6 is placed on the top of the placing platform 403, and both ends of the battery 6 are respectively abutted against the stop bar 404 and the metal elastic sheet 406. The placing platform 403 is used to place a battery 6 with the same specification and size as the battery compartment 301. By providing the stop bar 404 and the metal elastic sheet 406 on the placing platform 403, one end of the installed battery 6 abuts against the stop bar 403, and the other end abuts against the metal elastic sheet 406 through elastic deformation, thereby realizing the limitation of the battery 6 and preventing the battery 6 from slipping off the placing platform 403.

[0037] Specifically, a convex block is provided at the bottom of the housing 1, and the convex block is snap-fitted into the positioning groove 402. When replacing the battery, first snap-fix the positioning groove 402 on the replacement platform 401 with the convex block at the bottom of the housing 1, so as to align the position of the placing platform 403 with the position of the battery 6 in the battery compartment 301, and then realize the replacement of the battery 6. Ventilation grooves are provided around the convex block to dissipate heat from the PCB circuit board inside the housing 1. Embodiment 2 The embodiment of the present invention also provides a method for using a portable smoke detector fire alarm, and the method steps are as follows: When performing battery replacement operation on an independent smoke detector, the operator places the nine-volt square battery to be replaced on the placement table 403. Through the elastic deformation force of the metal elastic piece 406, the battery 6 to be replaced is clamped and fixed between the metal elastic piece 406 and the stop bar 404. When placing it, it is necessary to pay attention that the two electrodes of the nine-volt square battery face the side of the stop bar 404. The operator pushes the positioning assembly 4, the pushing assembly 5 and the battery 6 to be replaced placed on it upward by holding the holding rod 504, so that the replacement table 401 abuts against the bottom of the housing 1 and the positioning groove 402 sleeves on the convex position at the bottom of the housing 1 to achieve positioning. After completing the positioning, the operator pushes the holding rod 504 upward, causing the spring 501 to generate a reaction force. At this time, the force is transmitted to the pushing block 507 through the holding rod 504, the retaining ring 502, the extension rod 505 and the connecting rod 506, so that the pushing block 507 pushes upward. And because the top of the pushing block 507 is an inclined surface, the battery 6 to be replaced slides toward the battery compartment 301 when receiving the force from the top of the pushing block 507. With the application of the upward force, the battery 6 to be replaced abuts against the battery in the original battery compartment 301 and pushes the battery in the original battery compartment 301 until the two electrodes of the battery 6 to be replaced are electrically connected to the conductive elastic piece 202. At this time, the replaced old battery falls into the storage frame 407 from the other side of the battery compartment 301 under the action of its own gravity, thus completing the replacement operation of the new and old batteries.

[0038] In summary, a portable smoke detector for fire detection provided by the present invention has the following advantages: 1. The present invention can realize the rapid replacement of the battery through the positioning assembly and the pushing assembly. Maintenance personnel do not need to perform aerial operations by means of a stepladder, etc., improving the safety of maintenance. Since maintenance personnel do not need to carry a stepladder for inspection and maintenance, they only need to carry the positioning assembly, the pushing assembly and the battery to be replaced to realize the replacement of the battery, thus reducing the physical consumption caused by carrying a stepladder.

[0039] 2. The present invention pushes the battery through the pushing assembly, pushes out the battery originally installed in the battery compartment, and collects it through the storage frame, which can effectively avoid the situation of missing battery installation when personnel perform battery replacement and maintenance.

[0040] 3. The present invention can quickly position the battery to be replaced through the positioning assembly, avoiding the situation that personnel cannot position due to the high installation position of the sensor during operation, and further improving the battery replacement efficiency.
