Description

Technical Field

[0001] This application relates to the field of formaldehyde monitoring, and in particular to a formaldehyde monitoring alarm device. Background Technology

[0002] Formaldehyde monitoring and alarm devices are intelligent devices that use sensors to detect the formaldehyde concentration in the environment in real time and trigger an audible and visual alarm when the concentration exceeds the standard. They are widely used in residential, office, and laboratory settings. Existing devices typically consist of a sensor module, a signal processing unit, an alarm module, and a supporting structure. Their core function is to collect air samples through the detection port, analyze the data through the sensor, and output concentration data. When the value exceeds a preset threshold, an alarm is triggered.

[0003] Existing formaldehyde monitoring and alarm devices rely on tripods to fix the detection port at a certain height above the ground and sample through a thin connecting tube. However, because the detection port of the device is at a fixed height, it is difficult to adapt to the monitoring needs of indoor air environment at different heights. For example, formaldehyde released from furniture boards tends to accumulate in the middle layer, while formaldehyde released from flooring is close to the ground. The fixed-height monitoring method cannot fully cover pollution at all levels, resulting in poor monitoring effect and low accuracy.

[0004] In view of the aforementioned technologies, the inventors believe that formaldehyde monitoring alarm devices have the drawback of being inconvenient to adjust the detection height during use. Therefore, they have proposed a formaldehyde monitoring alarm device to solve the above problems. Utility Model Content

[0005] To address the issue of inconvenient adjustment of the detection height in formaldehyde monitoring alarm devices during use, this application provides a formaldehyde monitoring alarm device.

[0006] The formaldehyde monitoring and alarm device provided in this application adopts the following technical solution:

[0007] A formaldehyde monitoring and alarm device includes a monitoring device. A connector is provided at the top edge of the monitoring device. An air inlet pipe is installed on the upper surface of the connector. A universal ball joint is fixedly installed on the top side of the monitoring device. A support rod is movably connected to the outer surface of the universal ball joint. A fixing groove is opened on the upper surface of the support rod. A movable support rod is movably installed inside the fixing groove. A positioning mechanism is provided at the top of the movable support rod extending to the outside of the support rod for positioning and supporting the air inlet pipe.

[0008] The positioning mechanism includes a damping bearing, which is located at the top of the movable support rod. A movable component is rotatably installed inside the damping bearing. A support component is fixedly connected to the top of the movable component. A fixing groove is provided in the middle of the top of the support component.

[0009] A support structure is also provided below the monitoring equipment to provide stable support for the monitoring equipment.

[0010] Preferably, the support structure includes a tripod, which is supported below the monitoring equipment. Several support legs are movably provided at the bottom of the tripod, and support rollers are installed at the bottom of the support legs. A locking element is installed on one side of the outer surface of the support roller near the hinge shaft.

[0011] Preferably, the bottom end of the movable support rod extends into the fixed groove and is fixedly installed with an elastic block. The outer surface of the elastic block abuts against the inner wall of the fixed groove, and the fixed groove and the elastic block engage with each other.

[0012] Preferably, elastic limiting blocks are fused to the top of both sides of the inner wall of the fixing slot, one side of the outer surface of the air intake pipe is located inside the fixing slot, and the distance between the two elastic limiting blocks is greater than the outer diameter of the air intake pipe.

[0013] Preferably, the number of support legs is three, and a movable plate is hinged to the middle of one side of each support leg, with the three movable plates rotatably connected to each other.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. By incorporating a universal ball joint, support rod, and movable strut, the height and angle of the air intake pipe can be flexibly adjusted to meet the monitoring needs of indoor air environments at different heights, comprehensively covering pollution areas at all levels and improving monitoring effectiveness and accuracy. For example, it can be used to detect formaldehyde accumulation areas at different heights, such as the middle layer of furniture or near the floor.

[0016] 2. Through the cooperation of damping bearings, moving parts, support parts and fixed slots in the positioning mechanism, the air intake pipe can be stably positioned and supported. The elastic limit block can be adapted to air intake pipes of different diameters, ensuring that the air intake pipe is stable in position during the testing process and is not easy to move, thus ensuring the accuracy and continuity of the test.

[0017] 3. The support structure adopts a tripod with support legs, support rollers and locking components, which not only facilitates the movement of the device in different indoor locations, but also secures the support rollers with locking components to ensure stable placement of the device during monitoring. It is adaptable to various ground environments, such as uneven ground, thereby improving the convenience and stability of the device. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application discloses a formaldehyde monitoring and alarm device. (Refer to...) Figure 1-4 A formaldehyde monitoring and alarm device includes a monitoring device 1. A connector 2 is provided at the top edge of the monitoring device 1. An air inlet pipe 3 is installed on the upper surface of the connector 2. A universal ball joint 4 is fixedly installed on the top side of the monitoring device 1. A support rod 5 is movably connected to the outer surface of the universal ball joint 4. A fixing groove 6 is opened on the upper surface of the support rod 5. A movable support rod 7 is movably installed inside the fixing groove 6. An elastic block 8 is fixedly installed inside the fixing groove 6 at the bottom end of the movable support rod 7. The outer surface of the elastic block 8 abuts against the inner wall of the fixing groove 6. The fixing groove 6 and the elastic block 8 are engaged with each other. A positioning mechanism is provided at the top of the movable support rod 7 outside the support rod 5 for positioning and supporting the air inlet pipe 3.

[0025] The positioning mechanism includes a damping bearing 9, which is located at the top of the movable support rod 7. A movable part 10 is rotatably installed inside the damping bearing 9. A support part 11 is fixedly connected to the top of the movable part 10. A fixed slot 12 is opened in the middle of the top of the support part 11. Elastic limiting blocks 13 are fused to the top of both sides of the inner wall of the fixed slot 12. One side of the outer surface of the air intake pipe 3 is located inside the fixed slot 12. The distance between the two elastic limiting blocks 13 is greater than the outer diameter of the air intake pipe 3.

[0026] A support structure is also provided below the monitoring device 1 to provide stable support for the monitoring device 1.

[0027] As can be seen from the above, when using this device to adjust the height of the air intake pipe 3 and for positioning, the operator first pulls the movable support rod 7 according to the height to be monitored. The elastic block 8 at the bottom of the movable support rod 7 slides in the fixed groove 6. The elastic block 8 and the inner wall of the fixed groove 6 abut against each other to generate friction. After adjusting to a suitable height, the friction can be used to temporarily fix the movable support rod 7 in the current position (if more precise fixing is required, other fixing parts can be used later, but the abutment of the elastic block 8 in this structure can achieve a certain degree of position holding). Next, the operator rotates the damping bearing 9 at the top of the movable support rod 7, which drives the movable part 10 and the support part 11 to rotate, adjusting the orientation of the fixed groove 12 at the top of the support part 11 so that the air intake pipe 3 can be inserted into the fixed groove 12. Then, the air intake pipe 3 is inserted into the fixed slot 12. The air intake pipe 3 presses against the two elastic limiting blocks 13, causing the elastic limiting blocks 13 to deform. The elastic force of the elastic limiting blocks 13 is used to stably hold the air intake pipe 3 in the fixed slot 12, thereby achieving positioning and support for the air intake pipe 3. In this way, the air intake pipe 3 can stably collect air samples at a set height, which is convenient for monitoring the air environment at different heights.

[0028] Reference Figure 1 and Figure 4 The support structure includes a tripod 14, which is supported below the monitoring device 1. Several support legs 15 are movably arranged at the bottom of the tripod 14. Support rollers 16 are installed at the bottom of the support legs 15. A locking element 17 is installed on one side of the outer surface of the support rollers 16 near the hinge shaft. There are three support legs 15. A movable plate is hinged to the middle of one side of the support leg 15. The three movable plates are rotatably connected to each other.

[0029] As can be seen from the above, when using the support structure to support and move the monitoring device 1, if the operator needs to move the device, they can push the monitoring device 1, using the support rollers 16 at the bottom of the support legs 15 to roll, thus moving the entire device indoors and facilitating its movement to the desired monitoring location. Next, once the device is moved to the target location, the operator operates the locking piece 17 on the support rollers 16 to lock them, preventing them from rolling. Simultaneously, the movable plates hinged at the center of one side of the three support legs 15 cooperate to enhance the stability of the tripod 14, ensuring the monitoring device 1 is placed stably during monitoring. Even on uneven ground, the device can remain stable by adjusting the unfolding angle of the support legs 15.

[0030] The implementation principle of the formaldehyde monitoring and alarm device in this application embodiment is as follows: During use, the operator first adjusts the direction of the support rod 5 using the universal ball joint 4 according to the monitoring requirements. Then, by pulling the movable support rod 7, the height of the movable support rod 7 is adjusted using the cooperation of the elastic locking block 8 and the fixed groove 6. Afterwards, the damping bearing 9 is rotated to adjust the position of the support component 11, and the air inlet pipe 3 is inserted into the fixed groove 12 and fixed by the elastic limiting block 13, achieving stable placement of the air inlet pipe 3 at different heights to collect air samples at corresponding heights. When moving the device, the support rollers 16 are used to roll; after reaching the monitoring position, the locking component 17 locks the support rollers 16, and the tripod 14 and the movable plate work together to maintain the stability of the device, thereby achieving formaldehyde monitoring of air environments at different heights, solving the problem of fixed detection height in traditional devices, and improving the monitoring effect and accuracy.
