Description

Technical Field

[0001] The utility model relates to the technical field of environmental monitoring, in particular to a laboratory environmental monitoring device. Background Art

[0002] When conducting experimental research, laboratories need to use various chemical reagents or biological samples. Since some elements will produce toxic and harmful gases, the concentration or status of these dangerous factors will be monitored in real time through air quality monitors. Once an abnormality is detected, an alarm can be issued immediately to ensure the safety of laboratory personnel.

[0003] When conducting water-related experiments in the laboratory, such as chemical reactions and biological experiments, water vapor will be generated during these experiments, thereby increasing the indoor humidity. When the humid gas in the laboratory enters the air quality monitor, the moisture in the gas will interfere with the accurate detection of the gas composition by the sensor and measuring equipment, causing abnormal fluctuations or instability in the monitoring data, making it difficult to interpret the data, and making it difficult for experimenters to accurately judge the changing trends and potential problems of indoor air quality, thereby reducing the sensitivity of environmental monitoring in the laboratory. At the same time, the air quality monitor reduces the space occupied by the single air inlet pipe, but the source direction of the gas is too single, thereby reducing the comprehensiveness of the monitoring.

[0004] Therefore, a laboratory environment monitoring setting is urgently needed to solve the above problems. Utility Model Content

[0007] The drying mechanism comprises a drying chamber opened in the air inlet pipe, an electric heating tube is spirally wound in the drying chamber, and a slow-flow component for slowing down the flow of the gas to be detected is arranged in the air inlet pipe.

[0008] The slow flow component comprises a spiral plate fixedly connected to the air inlet pipe, and a drainage groove is provided on one side of the spiral plate.

[0009] The suction mechanism includes a plurality of suction pipes arranged on the side wall of the intake pipe, each of the suction pipes is arranged in a ring array, each of the suction pipes is connected to the side wall of the intake pipe by a rotating ball head, and a driving component for driving each of the suction pipes is provided in the intake pipe.

[0010] The driving assembly includes a threaded rod rotatably connected to the bottom wall of the air intake pipe, the side wall of the threaded rod is threadedly connected to two connecting plates symmetrically arranged with each other, the two connecting plates are fixedly connected with a driving ring, the opposite sides of the two driving rings are abutted against the side wall of one end of the suction pipe located inside the air intake pipe, the end of the air intake pipe away from the monitor body is fixedly connected to a motor, and the output end of the motor is connected to the threaded rod.

[0011] The two driving rings are made of rubber.

[0012] A guide assembly for guiding the movement of the drive ring is provided in the air intake pipe, and the guide assembly includes two T-shaped guide rods fixedly connected to the bottom wall of the air intake pipe, the two T-shaped guide rods are symmetrically arranged about the threaded rod, and the two connecting plates are slidably connected to the side walls of the T-shaped guide rods.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model heats the gas entering the air inlet pipe by setting a drying mechanism, thereby heating and evaporating the moisture in the gas to be detected, avoiding the accuracy of detection being affected by the excessive moisture of the gas to be detected, thereby improving the sensitivity of environmental monitoring in the laboratory. At the same time, under the action of the suction mechanism, while reducing the space occupied by the air inlet pipe, the up and down reciprocating movement of multiple suction pipes increases the multi-directionality of the gas source, thereby improving the comprehensiveness of laboratory monitoring.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] See also Figure 1-Figure 3 , a laboratory environment monitoring device shown in the figure includes a monitor body 101 and an air inlet pipe 102 arranged on one side of the monitor body 101, and also includes a drying mechanism arranged in the air inlet pipe 102 for drying the test gas in the laboratory and an inhalation mechanism arranged in the air inlet pipe 102 for multi-directional inhalation of the laboratory test gas;

[0022] The drying mechanism includes a drying chamber 201 opened in the air inlet pipe 102, an electric heating tube 202 is spirally wound in the drying chamber 201, and a slow-flow component for slowing down the flow of the gas to be detected is provided in the air inlet pipe 102;

[0023] It should be noted here that: through the setting of the drying mechanism, the gas entering the air inlet pipe 102 is heated, so that the moisture in the gas to be detected is heated and evaporated, avoiding the accuracy of the detection being affected by the excessive humidity of the gas to be detected, thereby improving the sensitivity of environmental monitoring in the laboratory. At the same time, under the action of the suction mechanism, while reducing the space occupied by the air inlet pipe 102, the up and down reciprocating movement of multiple suction pipes 401 increases the multi-directionality of the gas source, thereby improving the comprehensiveness of laboratory monitoring.

[0024] It is worth noting that: as an existing technology, the specific structure and working principle of air quality monitors have been mastered by people in this field, and will not be elaborated here.

[0025] See also Figure 2 and Figure 3 The slow flow assembly shown in the figure includes a spiral plate 301 fixedly connected to the air inlet pipe 102, and a drainage groove 302 is opened on one side of the spiral plate 301;

[0026] It should be noted here that when the gas in the laboratory enters the air inlet pipe 102, the spiral drainage of the drainage groove 302 of the spiral plate 301 causes the gas to flow for a longer time in the air inlet pipe 102, thereby increasing the time for heating the gas and further ensuring the evaporation effect of the water in the gas.

[0027] Working principle: When monitoring the environmental gas in the laboratory, firstly, the gas from all directions is sucked into the air inlet pipe 102 under the action of the suction mechanism, and then the electric heating tube 202 is energized, and the heating effect of the electric heating tube 202 is used to heat the gas entering the air inlet pipe 102, so as to heat and evaporate the moisture in the gas to be detected, so as to avoid affecting the accuracy of detection due to the excessive humidity of the gas to be detected, thereby improving the sensitivity of monitoring the environment in the laboratory;

[0028] When the gas in the laboratory enters the air inlet pipe 102, the spiral drainage of the drainage groove 302 of the spiral plate 301 allows the gas to flow in the air inlet pipe 102 for a longer time, thereby increasing the time for heating the gas and further ensuring the evaporation effect of the water in the gas.

[0029] Example 2

[0030] See also Figure 3 This embodiment further explains Example 1. The suction mechanism shown in the figure includes a plurality of suction pipes 401 arranged on the side wall of the intake pipe 102. Each suction pipe 401 is arranged in a ring array. Each suction pipe 401 is connected to the side wall of the intake pipe 102 by a rotating ball head 402. A driving component for driving each suction pipe 401 is provided in the intake pipe 102.

[0031] It should be noted here that: through the setting of the suction mechanism, under the action of the driving component, the end of the suction tube 401 located inside the air inlet pipe 102 is driven to move up and down, so that under the rotation of the rotating ball head 402, the end of the suction tube 401 located outside the air inlet pipe 102 is driven to move in the opposite direction, thereby reducing the space occupied by the air inlet pipe 102. At the same time, through the up and down reciprocating movement of multiple suction tubes 401, the multi-directionality of the gas source is increased, thereby improving the comprehensiveness of laboratory monitoring.

[0032] See also Figure 2 and Figure 3 The driving assembly shown in the figure includes a threaded rod 501 rotatably connected to the bottom wall of the air inlet pipe 102, and one end of the air inlet pipe 102 away from the monitor body 101 is sealed, and the side wall of the threaded rod 501 is threadedly connected to two connecting plates 502 symmetrically arranged with each other, and the two connecting plates 502 are fixedly connected with a driving ring 503, and the opposite side of the two driving rings 503 is against the side wall of one end of the suction pipe 401 located inside the air inlet pipe 102, and the end of the air inlet pipe 102 away from the monitor body 101 is fixedly connected with a motor 504, and the output end of the motor 504 is connected to the threaded rod 501;

[0033] It should be noted here that: through the setting of the driving component, the motor 504 is used to drive the threaded rod 501 to rotate, and under the threaded engagement transmission between the threaded rod 501 and the two connecting plates 502 and the guiding action of the guide component, the two driving rings 503 will be driven to move up and down in the intake pipe 102, so that the driving ring 503 and the side wall of one end of the suction pipe 401 located inside the intake pipe 102 will be driven to move up and down.

[0034] See also Figure 2 and Figure 3 , the two driving rings 503 shown in the figure are made of rubber;

[0035] It should be noted here that: by making the drive ring 503 of rubber material, when the drive ring 503 pushes one end of the suction pipe 401 located inside the intake pipe 102 to move up and down, when one end of the suction pipe 401 is tilted upward or downward, the deformation ability of the rubber material provides a position change space for the suction pipe 401 to tilt upward or downward.

[0036] See also Figure 2 and Figure 3 In the air intake pipe 102 shown in the figure, a guide assembly for guiding the movement of the driving ring 503 is provided, and the guide assembly includes two T-shaped guide rods 6 fixedly connected to the bottom wall of the air intake pipe 102, the two T-shaped guide rods 6 are symmetrically arranged about the threaded rod 501, and the two connecting plates 502 are slidably connected to the side walls of the T-shaped guide rods 6;

[0037] It should be noted here that: the setting of the guide component provides guidance and limiting functions for the movement of the drive ring 503.
