[0031] Respiratory diseases are diverse, many of which are caused by viruses and bacteria. These diseases are highly contagious, and people with weaker constitutions are easily infected by bacteria and viruses in the air, leading to respiratory illnesses. This is especially true in complex environments like hospitals, where there are many patients and the air contains a large number of viruses and bacteria. Medical staff can disinfect equipment and the department environment with ultraviolet light to prevent the spread of disease. However, to prevent staff from accidentally entering during ultraviolet irradiation, infrared alarms are usually installed at the entrance to alert staff.

[0032] In related technologies, springs and clamps are installed on the alarm. The springs pull the two clamps closer together, thereby clamping and fixing the mounting rod. However, the existing device is inconvenient to operate, requiring both hands to pull the clamps away and aligning the inner side of the clamps with the mounting rod during installation, which is also inconvenient.

[0033] To address some of the problems in related technologies, this application provides an alarm device for accidental entry into an ultraviolet disinfection room. When installing the infrared alarm body 12, the mounting plate 11 is first fixed to the door frame with bolts. Then, the slider 22 on the rear side of the infrared alarm body 12 is slidably installed into the slide groove 21. When sliding downwards, it will press the locking block 25. Due to the inclined design of the locking block 25, the locking block 25 will retract into the groove 23 during the pressing process, and the spring will be pressed during the retraction. Spring 24 is compressed until the top of slider 22 is misaligned with the top of block 25. Then, spring 24 rebounds and pushes block 25 out of the groove 23 to restrict slider 22. When disassembly is required, simply push the upright 29 upward to insert it into the mounting plate 11 and drive the pressing block 28 to press the protrusion 27, so that the protrusion 27 slides inside the through groove 26. At the same time, the block 25 retracts into the groove 23 to release the restriction on slider 22. Then, drag the infrared alarm body 12 to move slider 22 out of the slide groove 21.

[0034] This application is described below with reference to the accompanying drawings and specific embodiments:

[0035] This application provides an alarm device for accidental entry into an ultraviolet disinfection room, comprising: an infrared alarm body 12 disposed on the front surface of an mounting plate 11; a fixing component 2 disposed within the mounting plate 11, the fixing component 2 comprising: a sliding groove 21 formed on the front surface of the mounting plate 11; a slider 22 disposed on the outer side wall of the infrared alarm body 12 and slidably mounted with the sliding groove 21; a groove 23 formed on the inner side wall of the sliding groove 21; a spring 24 disposed inside the groove 23; a locking block 25 having one end inserted into the groove 23 and connected to the spring 24; a through groove 26 formed on the inner side wall of the groove 23; a protrusion 27 having one end penetrating the through groove 26 and connected to the locking block 25; a pressing block 28 disposed inside the mounting plate 11; and a vertical rod 29 having its top penetrating the bottom of the mounting plate 11 and connected to the pressing block 28.

[0036] Specifically, the infrared alarm unit itself, model 12 (LFang)KR-P6, works on the principle of detecting abnormal activity in the environment using infrared technology. It is mainly divided into two types: active and passive. Active infrared alarms actively emit infrared rays, which bounce back when they encounter obstacles and are received by the alarm's sensor. If the sensor detects stationary infrared rays (i.e., continuously emitted and bounced rays), the alarm will not sound; however, if a moving object violates these infrared rays, the sensor will detect the anomaly and trigger the alarm. Passive infrared alarms do not emit infrared rays but rely on detecting infrared rays emitted by objects in the environment. Any object with a temperature above absolute zero emits infrared rays; therefore, passive alarms trigger the alarm by detecting changes in the intensity of infrared rays in the environment.

[0037] When installing the infrared alarm body 12, firstly, the mounting plate 11 needs to be fixed to the door frame with bolts. Then, the slider 22 on the rear side of the infrared alarm body 12 is slidably installed into the groove 21. When sliding downwards, it will squeeze the locking block 25. Due to the inclined design of the locking block 25, the locking block 25 will retract into the groove 23 during the squeezing process. During the retraction, the spring 24 is squeezed and compressed until the top of the slider 22 and the locking block 25 are misaligned. Then, the spring 24 rebounds and pushes the locking block 25 out of the groove 23 to restrict the slider 22. When disassembly is required, simply push the upright 29 upwards into the mounting plate 11 and drive the squeezing block 28 to squeeze the protrusion 27, so that the protrusion 27 slides in the through groove 26. At the same time, the locking block 25 retracts into the groove 23 to release the restriction on the slider 22. Then, drag the infrared alarm body 12 to move the slider 22 out of the groove 21.

[0038] In some embodiments, the bottom of the slider 22 is designed with a slope, and the slope angle is consistent with the slope angle of the card block 25.

[0039] The beveled design allows for better contact and reduced scratches when the slider 22 presses against the card block 25.

[0040] In some embodiments, the protrusion 27 is designed in the shape of a round rod.

[0041] When in use, the round rod-shaped design of the protrusion 27 reduces friction and scratches when it comes into contact with the extrusion block 28.

[0042] In some embodiments, the fixing component 2 further includes a stop 281 disposed at the bottom of the pressing block 28.

[0043] The design of the stop 281 during use can prevent the height of the protrusion 27 from being lower than the bottom of the extrusion block 28, thus preventing the extrusion block 28 from separating from the protrusion 27.

[0044] In some embodiments, the fixing component 2 further includes a spring 282 disposed inside the mounting plate 11, with its top end connected to the bottom of the pressing block 28.

[0045] When in use, the design of spring 282 can push the extrusion block 28 and stabilize the position of the extrusion block 28.

[0046] In some embodiments, the fixing component 2 further includes a push plate 291 disposed at the bottom of the upright 29.

[0047] The design of the push plate 291 during use allows for a larger area at the bottom of the upright 29, resulting in greater comfort when pushing it.

[0048] In some embodiments, a spring-loaded assembly 3 is provided inside the slide 21. The spring-loaded assembly 3 includes: a groove 31 formed on the bottom inner wall of the slide 21; a spring 32 disposed inside the groove 31; and a push rod 33 whose bottom is inserted into the groove 31 and connected to the top of the spring 32.

[0049] When in use, when the slider 22 slides downward, it pushes the push rod 33 back into the inside of the groove 31 and simultaneously compresses the spring 32. Then, when the restriction on the slider 22 is released, the spring 32 rebounds and pushes the push rod 33 out of the inside of the groove 31, so that the push rod 33 pushes the slider 22 upward, which is convenient for disassembly.

[0050] In some embodiments, the rebound assembly 3 further includes a rubber block 34 disposed on the top of the push rod 33.

[0051] The design of the rubber block 34 during use can reduce the impact and act as a buffer when it collides with the slider 22.
