Description

Technical Field

[0001] This utility model relates to the field of safety cabinet technology, and in particular to a fireproof safety cabinet with alarm function. Background Technology

[0002] Safety cabinets are safety protection devices used to store hazardous materials. They reduce risks through classified storage and physical protection. Safety cabinets are widely used in laboratories, factories, and the medical industry. There are different types of safety cabinets, including chemical safety cabinets, biological safety cabinets, and fireproof safety cabinets. The appropriate type should be selected based on the type of items being stored. Fireproof safety cabinets with alarm functions can monitor and transmit information about fires inside the cabinet, allowing staff to take quick action. A search revealed Chinese patent CN214510201U, which discloses a fireproof safety cabinet with an alarm function. The cabinet includes a main body, a main shaft, and a ratchet. A smoke detector is mounted on the top of the main body, and a driven gear is located on the outer side of the smoke detector. A cleaning brush is mounted on the top surface of the driven gear. A motor is mounted on the top of the main body. This fireproof safety cabinet with an alarm function, by mounting a smoke detector on the top of the main body, allows the smoke detector to sound an alarm immediately upon detecting external smoke, thereby preventing the spread of fire and reducing losses. Simultaneously, the cleaning brush on the outer side of the smoke detector prevents dust accumulation on its surface after prolonged use, thus avoiding blockage of the smoke detector's detection port and preventing malfunction.

[0003] The above-mentioned technical solutions can only prevent the smoke detector from clogging and clean it. They cannot accelerate the contact between the air inside the safety cabinet and the smoke sensor, or provide more adequate heat dissipation inside the safety cabinet. This can easily lead to the smoke sensor being unable to detect the fire inside the safety cabinet in a timely manner, which is not conducive to fully improving the safety of the safety cabinet. Utility Model Content

[0004] The above-mentioned technical solutions only clean the smoke detector to prevent clogging, but cannot accelerate the contact between the air inside the safety cabinet and the smoke sensor, nor can they provide more adequate heat dissipation inside the safety cabinet. This can easily lead to the smoke sensor being unable to detect fire inside the safety cabinet in a timely manner, which is not conducive to improving the safety of the safety cabinet. Therefore, this utility model provides a fireproof safety cabinet with an alarm function.

[0005] The technical solution adopted by this utility model is: a fireproof safety cabinet with alarm function, comprising: The cabinet body of the safety cabinet; A smoke-sensing and heat-dissipating assembly is installed above the safety cabinet body.

A through hole is opened on the top surface of the waterproof cover. The through hole is used to facilitate the connection between the resonant plate and the alarm. The resonant plate passes through the lower part of the through hole.

[0009] Furthermore, a cleaning component is installed inside the fixed cylinder, which is used to clean the smoke sensor.

[0010] Furthermore, the cleaning component includes a servo motor, a gear, a rotating ring, and a brush. The servo motor is fixedly connected to the fixed cylinder, the gear is fixedly connected to the output shaft of the servo motor, the rotating ring is rotatably mounted inside the fixed cylinder, and a toothed groove is provided on the outer side of the rotating ring.

[0017] The following is in conjunction with the appendix Figure 1-5The present invention will be further described below.

[0018] To address the problems existing in the background technology, this application proposes the following technical solution: a fireproof safety cabinet with alarm function.

[0019] The specific technical solution includes a safety cabinet body 1 and a smoke-sensing heat dissipation component 2; like Figure 1-3 and Figure 5 As shown, the smoke-sensing heat dissipation assembly 2 is installed above the cabinet body 1 of the safety cabinet. The smoke-sensing heat dissipation assembly 2 is used to drive the gas flow inside the safety cabinet body 1 and to monitor the smoke inside the cabinet body 1. The smoke-sensing heat dissipation assembly 2 includes a conical cylinder 201, a diffuser fan 202, a fixing cylinder 203, a smoke sensor 204, and an alarm 205. The conical cylinder 201 can fix the bracket 206, and the tip of the conical cylinder 201 faces upwards and directly below the smoke sensor 204, allowing the gas ejected from inside the conical cylinder 201 to directly contact the smoke sensor 204. The diffuser fan 202 can drive the gas inside the safety cabinet body 1 into the conical cylinder 201. The fixing cylinder 203 can fix the smoke sensor 204, and the upper part of the fixing cylinder 203 can support the conical cylinder 201. The upper end of the cone 201 provides wind protection for the gas emitted from the top. The smoke sensor 204 can detect smoke from the gas emitted from the top of the cone 201. The alarm 205 can receive the alarm information transmitted by the smoke sensor 204 and then emit an alarm sound. The cone 201 is fixedly installed above the cabinet 1. A bracket 206 is fixedly installed inside the cone 201. The bracket 206 can fix the ventilation fan 202. The ventilation fan 202 is fixedly connected to the bracket 206. The fixed cylinder 203 is fixedly sleeved above the cone 201. The smoke sensor 204 is fixedly installed inside the upper end of the fixed cylinder 203. The alarm 205 is located above the smoke sensor 204. An air outlet 3 is opened on the lower side wall of the fixed cylinder 203 to facilitate the exhaust of gas inside the fixed cylinder 203.

[0020] By activating the ventilation fan 202, the gas inside the safety cabinet 1 is rapidly drawn into the conical cylinder 201. The gas inside the conical cylinder 201 is then rapidly ejected from its tip, forming a column shape. The gas ejected from the top of the conical cylinder 201 enters the fixed cylinder 203 and is rapidly sprayed onto the sensing point of the smoke sensor 204. The smoke sensor 204 can detect the gas it comes into contact with. When there is no smoke in the gas, it can be discharged from the vent 3 with the airflow. At this time, the hot air inside the safety cabinet 1 can be discharged, which can dissipate heat from the inside of the safety cabinet 1 and reduce the temperature inside the safety cabinet 1, which is conducive to a more suitable environment for the items stored inside the safety cabinet 1. When there is smoke in the gas, the smoke sensor 204 can send a signal and transmit it to the alarm 205, which can then sound an alarm to alert the staff.

[0021] like Figure 1 , Figure 3 and Figure 5 As shown, a ringing assembly 4 is installed below the alarm 205. The ringing assembly 4 is used to amplify the alarm sound. The ringing assembly 4 includes a resonant plate 401, a striking hammer 402, and a limiting hammer 403. The resonant plate 401 can receive the vibration transmitted by the alarm 205. The striking hammer 402 can strike the limiting hammer 403. The limiting hammer 403 and the striking hammer 402 strike each other to produce a sound. The resonant plate 401 is fixedly installed below the alarm 205. The striking hammer 402 is fixedly installed at the lower end of the resonant plate 401. The limiting hammer 403 is sleeved on the upper and lower ends of the striking hammer 402.

[0022] When the alarm 205 sounds, the sound can be transmitted to the resonant plate 401. The resonant plate 401 vibrates and transmits the vibration to the striking hammer 402. The striking hammer 402 vibrates and strikes the limiting hammer 403. The limiting hammer 403 and the striking hammer 402 collide with each other and make a sound, which helps to increase the alarm sound.

[0023] like Figure 1 and Figure 5 As shown, a waterproof cover 5 is fixedly installed on the top of the safety cabinet body 1. The waterproof cover 5 supports the alarm 205 and provides waterproof protection for the top of the fireproof safety cabinet. The waterproof cover 5 also provides waterproof protection for the safety cabinet body 1, the conical cylinder 201, the ventilation fan 202, the fixing cylinder 203, the smoke detector 204, the resonant plate 401, the striking hammer 402, and the limiting hammer 403. The alarm 205 is fixedly installed on the top of the waterproof cover 5. A through hole 6 is provided on the top surface of the waterproof cover 5. The through hole 6 facilitates the connection between the resonant plate 401 and the alarm 205. The resonant plate 401 passes through the lower part of the through hole 6.

[0024] like Figure 4-5As shown, a cleaning component 7 is installed inside the fixed cylinder 203. The cleaning component 7 is used to clean the smoke sensor 204. The cleaning component 7 includes a servo motor 701, a gear 702, a rotating ring 703, and a brush 704. The servo motor 701 can drive the gear 702 to rotate. The gear 702 can drive the rotating ring 703 to rotate through the tooth groove 8. The brush 704 can wipe the sensing point of the smoke sensor 204. The servo motor 701 is fixedly connected to the fixed cylinder 203. The gear 702 is fixedly connected to the output shaft of the servo motor 701. The rotating ring 703 is rotatably installed inside the fixed cylinder 203. The rotating ring 703 has a tooth groove 8 on its outer side. The tooth groove 8 can facilitate the connection between the gear 702 and the rotating ring 703. The tooth groove 8 is used to drive the gear 702 and the rotating ring 703 to move together. The gear 702 meshes with the tooth groove 8. The brush 704 is fixedly installed inside the rotating ring 703.

[0025] The servo motor 701 starts and drives the gear 702 to rotate. The gear 702 can drive the rotating ring 703 to rotate through the tooth groove 8. The rotating ring 703 can drive the brush 704 to rotate around the outside of the smoke sensor 204. The bristles of the brush 704 can clean the smoke sensor 204 and prevent dust from clogging the smoke sensor 204 and causing it to malfunction.

[0026] like Figure 1 and Figure 5 As shown, a filter plate 9 is fixedly installed on the side wall of the safety cabinet 1. The filter plate 9 can filter the gas entering the safety cabinet 1. The filter plate 9 is used to allow air to pass through the safety cabinet 1 and to filter the air entering the safety cabinet 1.
