[0001] The present application relates to the field of VOC detection technology, and in particular to a VOC monitoring device. Background Art

[0002] VOC stands for volatile organic compounds. Generally speaking, VOC refers to volatile organic compounds. According to the World Health Organization, VOCs are compounds with a boiling point between 50°C and 250°C, a saturated vapor pressure exceeding 133.32 kPa at room temperature, and a vaporous presence in the air at room temperature. However, in an environmental context, VOCs are defined as reactive volatile organic compounds (VOCs), meaning those that can cause harm.

[0003] In order to detect the content of VOC, a VOC monitoring device is usually used to monitor the content of VOC. However, the existing VOC monitoring device is often difficult to adjust the size and speed of the VOC airflow during use, resulting in low monitoring efficiency of the VOC monitoring device.

[0021] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0022] The present application provides a VOC monitoring device.

[0023] like Figure 1 、 Figure 2 and Figure 3 As shown, in one embodiment of the present application, the VOC monitoring device includes a monitoring box 100 , a monitoring component 200 and an adjustment component 300 .

[0024] The monitoring box 100 includes a monitoring chamber 101 and a storage chamber 102. The monitoring assembly 200 includes a monitor 201, a partition plate 202, a filter plate 203, and a filter hole 204. The partition plate 202 is fixedly connected to the monitoring box 100 to separate the monitoring box 100 into the monitoring chamber 101 and the storage chamber 102. The monitor 201 is fixedly connected to the side wall of the partition plate 202. The filter plate 203 is fixedly connected to the storage chamber 102. The filter hole 204 is opened in the filter plate 203. The adjustment assembly 300 includes an adjustment plate 301, an adjustment member 302, an adjustment rod 303 and a positioning member 304. The adjustment member 302 is arranged at the connection between the adjustment plate 301 and the partition plate 202. The adjustment plate 301 is slidably connected to the monitoring box 100. One end of the adjustment rod 303 is fixedly connected to the side wall of the adjustment plate 301. The other end of the adjustment rod 303 passes through the monitoring box 100 and extends to the outside. The positioning member 304 is fixedly connected to the adjustment rod 303.

[0025] Specifically, the partition plate 202 and the filter plate 203 abut against each other, and the surface of the partition plate 202 is provided with holes corresponding to the filter holes 204, so that the VOC airflow can enter the filter holes 204 through the holes of the partition plate 202 after the monitoring is completed, and enter the storage chamber 102 after being filtered by the filter plate 203.

[0026] In this embodiment, VOC gas enters the monitoring chamber 101 and is monitored by the monitor 201. After the monitoring is completed, the VOC gas passes through the filter plate 203 and reaches the storage chamber 102. The position of the adjustment plate 301 can be adjusted by the adjustment member 302, and after the position of the adjustment plate 301 is determined, the position of the adjustment plate 301 is fixed by the positioning member 304, thereby controlling the width of the VOC airflow channel, and then adjusting the passing speed of the VOC airflow to adjust the monitoring efficiency of the monitor 201. The present application can adjust the speed of the VOC airflow by adjusting the width of the VOC airflow channel, so that the detection efficiency of the monitor 201 can be controlled.

[0027] like Figure 1 and Figure 3 As shown, in one embodiment of the present application, the positioning member 304 includes a positioning hole 305, a positioning rod 306 and a reset spring 307, the positioning hole 305 is opened on the side wall of the adjusting rod 303, the positioning rod 306 is clamped in the positioning hole 305, one end of the reset spring 307 is fixedly connected to the side wall of the monitoring box 100, and the other end of the reset spring 307 is fixedly connected to the side wall of the adjusting plate 301.

[0028] In this embodiment, the adjustment plate 301 is driven to move by moving the adjustment rod 303, and then the position of the adjustment plate 301 is adjusted. After the position of the adjustment plate 301 is changed, the width of the VOC airflow channel is also changed, thereby adjusting the speed of the VOC airflow entering the monitoring box 100.

[0029] After the position of the adjustment plate 301 is determined, the positioning rod 306 is passed through the positioning hole 305 and is pressed against the outer wall of the monitoring box 100 to fix the position of the adjustment rod 303 and thus the position of the adjustment plate 301 .

[0030] After the monitoring is completed, the positioning rod 306 is disengaged from the positioning hole 305. After the positioning rod 306 is disengaged, the return spring 307 works to drive the adjustment plate 301 back to the initial position.

[0031] like Figure 3 As shown, in one embodiment of the present application, a plurality of positioning holes 305 are provided, and the plurality of positioning holes 305 are arranged at equal intervals on the adjustment rod 303 , and the diameter of the positioning hole 305 is equal to the diameter of the positioning rod 306 .

[0032] Specifically, the smaller the interval between the positioning holes 305, the smaller the minimum distance of the adjustment rod 303 in a single adjustment, thereby reducing the minimum moving distance of the adjustment rod 303 and the adjustment plate 301 in a single adjustment, so that the position adjustment of the adjustment plate 301 is more precise.

[0033] The length of the positioning rod 306 is greater than the width of the adjusting rod 303 .

[0034] In this embodiment, the position of the adjustment rod 303 is fixed by the positioning hole 305 in coordination with the positioning rod 306, thereby fixing the position of the adjustment plate 301. Since the length of the positioning rod 306 is greater than the width of the adjustment rod 303, the positioning rod 306 will have a portion that exceeds the adjustment rod 303 after passing through the positioning hole 305. This portion will abut against the outer wall of the monitoring box 100, thereby preventing the positioning rod 306 from continuing to move toward the center of the monitoring box 100. Since a reset spring 307 is provided between the adjustment plate 301 and the inner wall of the monitoring box 100, the reset spring 307 will also prevent the adjustment plate 301 and the adjustment rod 303 from moving away from the center of the monitoring box 100, thereby keeping the position of the adjustment plate 301 stable.

[0035] like Figure 2 As shown, in one embodiment of the present application, the adjusting member 302 includes an adjusting groove 302a and an adjusting slider 302b, the adjusting groove 302a is opened on the side wall of the partition plate 202, and the adjusting slider 302b is fixedly connected to the side wall of the adjusting plate 301, and the adjusting slider 302b is slidably connected to the adjusting groove 302a to enable the adjusting plate 301 to slide along the partition plate 202.

[0036] Specifically, the width of the adjusting slider 302b is equal to the width of the adjusting slot 302a.

[0037] In this embodiment, since the adjustment plate 301 will move under the drive of the adjustment rod 303, in order to maintain the stability of the adjustment plate 301, an adjustment member 302 is provided between the adjustment plate 301 and the partition plate 202 to improve the stability of the adjustment plate 301.

[0038] When the adjustment plate 301 moves, the adjustment slider 302b will slide in the adjustment groove 302a along with the movement of the adjustment plate 301. Since the adjustment groove 302a is opened on the surface of the partition plate 202, the adjustment plate 301 can always rest against the surface of the partition plate 202 without deviation when moving, thereby ensuring the stability of the adjustment plate 301 when moving.

[0039] like Figure 1 As shown, in one embodiment of the present application, there are two adjustment slots 302a, and the two adjustment slots 302a are symmetrically arranged about the central axis of the monitor 201. At least one adjustment slider 302b is slidably connected in each of the adjustment slots 302a.

[0040] In this embodiment, the two adjustment slots 302a correspond to two adjustment plates 301 respectively. Each adjustment plate 301 can slide along the corresponding adjustment slot 302a under the guidance of the adjustment slider 302b, thereby making the position adjustment of the adjustment plate 301 more stable and making the width adjustment of the VOC airflow channel more precise.

[0041] like Figure 1 and Figure 5 As shown, in one embodiment of the present application, the monitoring box 100 is provided with an inlet 100a and an outlet 100b, and the inlet 100a and the outlet 100b are respectively arranged at the two ends of the monitoring box 100, the inlet 100a is connected to the monitoring chamber 101, and the outlet 100b is connected to the storage chamber 102.

[0042] Specifically, since part of the pipeline connected to the monitoring box 100 is cylindrical, the inlet 100a of the detection box can also be set to a circular shape, so that the monitoring box 100 fits better with the external pipeline to reduce VOC gas leakage.

[0043] In this embodiment, the VOC airflow enters the monitoring box 100 through the inlet 100a, and reaches the monitor 201 through the VOC airflow channel formed by the adjustment plate 301. After the monitor 201 analyzes the relevant indicators of the VOC airflow, it passes through the filter plate 203 and is finally discharged from the monitoring box 100 through the outlet 100b.

[0044] like Figure 1 As shown, in one embodiment of the present application, the VOC monitoring device also includes an auxiliary connecting member 103, which is arranged at the inlet 100a of the monitoring box 100. The auxiliary connecting member 103 includes a connecting plate 104 and a connecting spring 105. One end of the connecting spring 105 is fixedly connected to the inlet 100a of the monitoring box 100, and the other end of the connecting spring 105 is fixedly connected to the connecting plate 104.

[0045] Optionally, if the inlet 100a of the monitoring box 100 is set to be circular, then in order to fit the inlet 100a of the monitoring box 100, the connecting plate 104 can also be set to be arc-shaped, thereby improving the fit between the connecting plate 104 and the external pipeline.

[0046] In this embodiment, in order to improve the stability and airtightness of the connection between the monitoring box 100 and the external pipeline, an auxiliary connecting piece 103 is provided to adjust the size of the inlet 100a of the monitoring box 100 so that the external pipeline can be clamped between the two connecting plates 104.

[0047] The angle of the connecting plate 104 is adjusted by the connecting spring 105, so that the external pipeline is clamped between the two connecting plates 104. Since the connecting spring 105 is elastic, the pressure between the connecting plate 104 and the external pipeline is increased, thereby improving the stability of the connection between the external pipeline and the monitoring box 100.

[0048] like Figure 1 As shown, in one embodiment of the present application, at least two connecting plates 104 are provided, and the two connecting plates 104 are symmetrically arranged about the center line of the inlet 100a of the monitoring box 100, and the two connecting plates 104 abut against each other.

[0049] Specifically, the number of the connecting springs 105 should be greater than or equal to the number of the connecting plates 104 , and each connecting plate 104 is connected to at least one connecting spring 105 .

[0050] In this embodiment, the external pipeline is fixed from different directions by multiple connecting plates 104 , so that the forces from different directions applied to the external pipeline are equal, thereby maintaining the stability of the connection between the external pipeline and the monitoring box 100 .

[0051] like Figure 1 As shown, in one embodiment of the present application, there are two adjustment plates 301 , and the two adjustment plates 301 are symmetrically arranged about the central axis of the monitoring box 100 , and a VOC airflow channel is formed between the two adjustment plates 301 .

[0052] In this embodiment, after entering the monitoring box 100 , the VOC airflow passes through the VOC airflow channel formed between the two adjustment plates 301 to reach the monitor 201 , and the monitor 201 completes the monitoring of the VOC airflow.

[0053] Since the position of the adjustment plate 301 can be adjusted, the width of the VOC airflow channel can also be adjusted. When the two adjustment plates 301 are close to each other, the width of the VOC airflow channel becomes smaller, and when the two adjustment plates 301 are away from each other, the width of the VOC airflow channel becomes larger.

[0054] The VOC airflow velocity is adjusted by adjusting the width of the VOC airflow channel, thereby controlling the monitoring efficiency of the monitor 201 .

[0055] The faster the VOC airflow speed is, the higher the monitoring efficiency of the monitor 201 per unit time is, and the slower the VOC airflow speed is, the lower the monitoring efficiency of the monitor 201 per unit time is.

[0056] like Figure 2 As shown, in one embodiment of the present application, a plurality of filter holes 204 are provided, and the plurality of filter holes 204 are arranged at equal intervals on the filter plate 203 .

[0057] In this embodiment, after monitoring, the VOC airflow passes through the filter holes 204 of the filter plate 203 and reaches the storage chamber 102. Some of the harmful gases contained in the VOC airflow are absorbed by the filter plate 203 to reduce the pollution of the VOC airflow to the environment.

[0058] The various technical features of the above-described embodiments can be combined arbitrarily, and the execution order of the method steps is not restricted. In order to make the description concise, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be determined by the appended claims.
