[0002] With the increasing demands for building safety, emergency response devices based on smoke and gas detection have become crucial facilities for ensuring the safety of people and property within buildings. However, existing devices have significant drawbacks in practical applications: long-term exposure to the external environment leads to the accumulation of large amounts of dust at the air inlet, requiring regular manual cleaning as automatic cleaning is not possible, thus increasing maintenance costs. Furthermore, these devices can obstruct gas flow, reducing detection sensitivity and affecting the timeliness and accuracy of emergency responses.

[0003] Therefore, in order to solve the above problems, how to design a building safety emergency response device is a technical problem that the industry urgently needs to solve. Utility Model Content

[0004] The purpose of this invention is to provide a building safety emergency response device to solve the problem mentioned in the background art that dust can reduce the detection sensitivity of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A building safety emergency response device includes a main housing with an installation frame on it. A storage cavity is provided between the installation frame and the main housing. A power device is provided on the inner wall of the storage cavity, penetrating through the inner wall of the storage cavity. The power device is provided with several sets of rotating components. Each rotating component includes a rotating disk located outside the installation frame. A set of filter chambers is provided on the rotating disks, and a filter screen is provided on the inner wall of the filter chambers.

[0006] Preferably, the power unit includes a power motor located on the main housing. The power motor has a drive shaft at its drive end, which is located inside the storage cavity. A bevel gear I is mounted on the power shaft, and several sets of bevel gear II are mounted on the bevel gear I. The bevel gear II meshes with the bevel gear I. A rotating shaft is located at the end of the bevel gear II away from the bevel gear I. The other end of the rotating shaft is rotatably connected to the inner wall of the mounting frame. The end of the rotating shaft away from the bevel gear II is connected to a rotating disc, and they correspond to each other.

[0007] Preferably, the mounting frame is provided with several sets of air inlet chambers and air outlet chambers arranged in sequence and communicating with the storage chamber. The air inlet chambers and air outlet chambers are covered by a rotating assembly. The air inlet chambers and air outlet chambers are distributed in a mirror symmetrical manner with the rotating axis as the center. The air outlet chamber is located on the side closer to the main housing. The air inlet chamber is provided with an air exchange assembly. The air inlet chambers and air outlet chambers correspond to a set of filter chambers.

[0008] Preferably, the ventilation assembly includes a feed plate connected to the inner wall of the air inlet chamber, a ventilation motor is provided inside the feed plate, a ventilation shaft is provided at the drive end of the ventilation motor, and ventilation fan blades are provided on the ventilation shaft.

[0009] Preferably, the mounting frame is provided with a detection component, the detection component includes a smoke sensor, the smoke sensor is connected to the inner wall of the storage cavity, and the mounting frame is provided with a buzzer, the smoke sensor is electrically connected to the buzzer.

[0010] Preferably, the mounting frame is provided with several sets of collection devices, which are matched and correspond one-to-one with the rotating components. Each collection device includes a mounting plate, and a guide frame is provided on the end face of the mounting plate away from the mounting frame. The rotating wheel is located between the guide frame and the mounting frame. A guide cavity is provided in the guide frame, and the air inlet of the guide cavity corresponds to the filter cavity on the side near the main housing. An inclined storage frame is provided on the side of the guide frame away from the main housing. A disassembly frame is provided in the storage frame, and the disassembly frame is inserted into the storage frame. A second filter screen is provided on the side of the disassembly frame away from the storage frame. A storage cavity is provided in the disassembly frame, and the storage cavity communicates with the guide cavity. The storage frame is detachably connected to the disassembly frame through a feeding component.

[0011] Preferably, the feeding assembly includes a support frame connected to a storage frame. The support frame has a guide post that extends through it. The guide post is polygonal. A connecting block is provided at one end of the guide post near the disassembly frame. The connecting block is connected to the support frame via a limiting spring. The disassembly frame has a positioning cavity, and the connecting block is inserted into the positioning cavity.

[0012] The beneficial effects of this utility model are: 1. Due to prolonged use, external dust will accumulate on the filter screen corresponding to the air inlet chamber. At this time, the power motor in the power unit starts, which drives the power shaft and the bevel gear to rotate. Since the bevel gear two meshes with the bevel gear one, it drives the bevel gear two and the rotating shaft to rotate, thereby driving the rotating disk to rotate 180 degrees. This replaces the positions of the filter screen one corresponding to the air inlet chamber and the filter screen one corresponding to the air outlet chamber. This, combined with the airflow, achieves continuous cleaning of the dust on the filter screen one corresponding to the air inlet chamber, thus achieving an automatic cleaning effect. This further ensures the secondary utilization of air during the detection of airflow, thereby achieving a cleaning effect.

[0013] 2. Furthermore, the cleaned dust will enter the guide cavity of the guide frame and then flow into the storage cavity of the disassembly frame. At this time, the dust will be separated and stored by the second filter screen, thereby storing the dust, extending the service life of the building safety emergency response device, and further ensuring the sensitivity of the building safety emergency response device.

[0014] 3. The dismantling frame for storing dust can also be removed by pulling the guide column of the feed component, which will cause the connecting block to move away from the positioning cavity. The dismantling frame can then be removed directly. Furthermore, the inclined installation of the storage frame ensures that dust will not fall during the dismantling process, further simplifying the cumbersome dismantling process and ensuring the practicality and convenience of the building safety emergency response device.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] See Figures 1-7 This utility model provides a building safety emergency response device, including a main housing 1, a mounting frame 5 on the main housing 1, a storage cavity 51 between the mounting frame 5 and the main housing 1, a power device 2 penetrating the inner wall of the storage cavity 51, and several sets of rotating components 3 on the power device 2. Each rotating component 3 includes a rotating disk 31 located outside the mounting frame 5, and a set of filter chambers 32 on the rotating disk 31, with a filter screen 33 on the inner wall of the filter chamber 32. When the power device 2 is activated, the rotating disk 31 in the several sets of rotating components 3 begins to rotate. When it rotates 180 degrees, the filter screen 33 in the filter chamber 32 on the rotating disk 31 is replaced, thereby extending the service life.

[0019] See Figure 3Specifically, the power unit 2 includes a power motor 21 located on the main housing 1. The drive end of the power motor 21 has a power shaft 22 located within the storage cavity 51. The power shaft 22 has a bevel gear 23, and the bevel gear 23 has several sets of bevel gears 24 meshing with the bevel gear 23. A rotating shaft 25 is located at the end of the bevel gear 24 away from the bevel gear 23, and the other end of the rotating shaft 25 is rotatably connected to the inner wall of the mounting frame 5. The end of the rotating shaft 25 away from the bevel gear 24 is connected to and corresponds one-to-one with the rotating disk 31. When the power motor 21 in the power unit 2 starts, it drives the power shaft 22 and the bevel gear 23 to rotate. Because the bevel gears 24 and the bevel gear 23 mesh, they in turn drive the bevel gears 24 and the rotating shaft 25 to rotate, thereby causing the rotating disk 31 to rotate 180 degrees.

[0020] See Figures 3-5 Specifically, the mounting frame 5 is provided with several sets of air inlet chambers 7 and exhaust chambers 9 arranged in sequence, and they communicate with the storage chamber 51. The air inlet chambers 7 and exhaust chambers 9 are covered by the rotating assembly 3. The air inlet chambers 7 and exhaust chambers 9 are distributed in a mirror symmetrical manner with the rotating shaft 25 as the center. The exhaust chamber 9 is located on the side closer to the main housing 1. The air inlet chamber 7 is provided with a ventilation assembly 4. The air inlet chamber 7 and exhaust chamber 9 correspond to a set of filter chambers 32. At this time, the ventilation assembly 4 is activated, thereby drawing in outside air, which enters the air inlet chamber 7 through the filter screen 33 corresponding to the air inlet chamber 7 on the rotating wheel 31, and then enters the storage chamber 51, thereby being discharged through the exhaust chamber 9, and then discharged through the filter screen 33 corresponding to the exhaust chamber 9.

[0021] See Figures 3-5 Specifically, the ventilation assembly 4 includes a feed plate 41 connected to the inner wall of the air inlet chamber 7. A ventilation motor 42 is housed within the feed plate 41, and a ventilation shaft 43 is mounted on the drive end of the ventilation motor 42. Ventilation fan blades 44 are mounted on the ventilation shaft 43. When the ventilation motor 42 in the ventilation assembly 4 starts, it drives the ventilation shaft 43 and ventilation fan blades 44 to rotate, thereby drawing in outside air.

[0022] See Figures 3-5 Specifically, the mounting frame 5 is equipped with a detection component 8, which includes a smoke sensor 81 connected to the inner wall of the storage chamber 51. The mounting frame 5 is also equipped with a buzzer 82, and the smoke sensor 81 is electrically connected to the buzzer 82. When air enters the storage chamber 51, the smoke sensor 81 detects the smoke concentration in the air. When the concentration reaches a certain level, the buzzer 82 sounds an alarm.

[0023] More preferably, the smoke sensor 81 adopts the MQ-2 digital output type smoke sensor to detect the smoke concentration and can be directly connected to the buzzer 82.

[0024] See Figures 3-5 Specifically, the mounting frame 5 is provided with several sets of collection devices 6, which cooperate with and correspond one-to-one with the rotating assembly 3. Each collection device 6 includes a mounting plate 68, and a guide frame 61 is provided on the end face of the mounting plate 68 away from the mounting frame 5. The rotating wheel 31 is located between the guide frame 61 and the mounting frame 5. A guide cavity 62 is provided inside the guide frame 61. The air inlet of the guide cavity 62 corresponds to the filter cavity 32 on the side near the main housing 1. An inclined storage frame 63 is provided on the side of the guide frame 61 away from the main housing 1. A disassembly frame 64 is provided inside the storage frame 63. The disassembly frame 64 is inserted into the storage frame 63. A filter screen 65 is provided on the side of the disassembly frame 64 away from the storage frame 63. A storage cavity 66 is provided inside the disassembly frame 64. The storage cavity 66 communicates with the guide cavity 62. The storage frame 63 is detachably connected to the disassembly frame 64 through a feeding assembly 67. When the air passes through the filter screen 33 corresponding to the exhaust chamber 9, it will enter the guide chamber 62 of the guide frame 61 and then flow into the storage chamber 66 of the disassembly frame 64. At this time, the dust and air are separated and stored by the filter screen 65. When the dust needs to be cleaned, the feed component 67 needs to be controlled.

[0025] See Figures 3-5 Specifically, the feeding assembly 67 includes a support frame 671 connected to the storage frame 63. A guide post 672, which penetrates the support frame 671, is provided on the support frame 671. The guide post 672 is polygonal, and a connecting block 673 is provided at one end of the guide post 672 near the disassembly frame 64. The connecting block 673 is connected to the support frame 671 via a limiting spring 675. The disassembly frame 64 has a positioning cavity 674, and the connecting block 673 is inserted into the positioning cavity 674. When the guide post 672 of the feeding assembly 67 is pulled, the connecting block 673 begins to move away from the positioning cavity 674, allowing the disassembly frame 64 to be directly removed.

[0026] Working principle of this utility model: When in use, the ventilation motor 42 in the ventilation assembly 4 on the inner wall of the air inlet chamber 7 starts, driving the ventilation shaft 43 and the ventilation fan blades 44 to rotate, thereby drawing in outside air through the filter screen 33 on the rotating disc 31 away from the main housing 1 and into the air inlet chamber 7, and then into the storage chamber 51, and then out of the exhaust chamber 9. After passing through the filter screen 33 near the main housing 1, the air is discharged, thus realizing the air flow. When the air enters the storage chamber 51, the smoke sensor 81 detects the smoke concentration in the air. When it does not meet the standard, the buzzer 82 sounds an alarm.

[0027] Due to prolonged use, external dust accumulates on the filter screen 33 corresponding to the air inlet chamber 7. At this time, the power motor 21 in the power unit 2 starts, thereby driving the power shaft 22 and the bevel gear 23 to rotate. Since the bevel gear 24 meshes with the bevel gear 23, it drives the bevel gear 24 and the rotating shaft 25 to rotate, thereby driving the rotating disk 31 to rotate 180 degrees. This replaces the position of the filter screen 33 corresponding to the air inlet chamber 7 and the filter screen 33 corresponding to the air outlet chamber 9. This, combined with the airflow, continuously cleans the dust on the filter screen 33 corresponding to the air inlet chamber 7, thus achieving an automatic cleaning effect.

[0028] Furthermore, the cleaned dust will enter the guide cavity 62 of the guide frame 61 and then flow into the storage cavity 66 of the disassembly frame 64. At this time, the dust will be separated and stored by the filter screen 65, thereby storing the dust and extending the service life of the building safety emergency response device.

[0029] The disassembly frame 64, which stores dust, can also be removed by pulling the guide post 672 of the feed assembly 67, which causes the connecting block 673 to move away from the positioning cavity 674.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
