Description

Technical Field

[0001] This utility model relates to the field of air sampler technology, specifically to an air sampler sampling head with automatic angle adjustment. Background Technology

[0002] An air sampler is a device used to collect pollutants or other substances from the air. There are many types of air samplers. Based on the sampling method, they can be divided into active samplers and passive samplers; based on the sampled object, they can be divided into gas samplers and particulate samplers; and based on the sampling time, they can be divided into continuous samplers and intermittent samplers.

[0003] The sampling head of an air sampler is a crucial component, responsible for collecting samples from the air. The sampling port within the sampling head collects the air sample and requires excellent sealing and stability to ensure the sampling process is unaffected by external factors. Furthermore, the sampling head must be easy to install and remove for convenient maintenance and upkeep.

[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. Existing sampling heads are often fixed, so it is difficult to flexibly adjust their sampling angle according to actual sampling needs; 2. The position of existing sampling heads is fixed, and when sampling, their sampling range is limited, making it difficult to comprehensively collect air samples from different areas. Utility Model Content

[0005] The purpose of this invention is to provide an automatically adjustable air sampler head to address the problems mentioned in the background art, where existing sampling heads are often fixed, making it difficult to flexibly adjust their sampling angle according to actual sampling needs. Furthermore, the fixed position of existing sampling heads limits their sampling range, hindering the comprehensive collection of air samples from different areas. To achieve the above objective, this invention provides the following technical solution: an automatically adjustable air sampler head, comprising a telescopic hose, a collar fitted onto one side of the outer wall of the telescopic hose, an electric telescopic rod screwed to the bottom side of the collar, the bottom end of the electric telescopic rod screwed to the top side of a top plate, a base rotatably connected to the bottom end of the top plate, a rotating mechanism screwed to one side of the bottom wall of the base, a filtering mechanism screwed to the bottom of the base, and a connecting pipe screwed to the bottom of the filtering mechanism.

[0006] More preferably, the bottom end of the telescopic hose is provided with an air intake pipe, which vertically penetrates the interior of the top plate and the base.

[0007] More preferably, the collar and the electric telescopic rod together constitute an adjustment mechanism.

[0008] More preferably, the rotating mechanism includes a motor, a rotating shaft, a driving gear, and a driven gear ring. The bottom end of the motor is screwed to one side of the bottom wall of the base. The output end of the motor is inserted into the driving gear. One side of the driving gear is engaged with the driven gear ring. The driven gear ring is sleeved on the outer wall of the top end of the air duct.

[0009] More preferably, the bottom outer edge of the top plate is provided with a protruding ring, and the top outer edge of the base is provided with a rotating groove, the protruding ring and the rotating groove forming a rotatable connection.

[0010] More preferably, the filtration mechanism includes a mounting screw plate, a fixing sleeve, and a filter element, wherein the mounting screw plate is disposed on the annular outer wall of the fixing sleeve, and the filter element is disposed inside the fixing sleeve.

[0011] More preferably, the annular outer wall of the base is provided with a first screw plate, and the annular outer wall of the connecting pipe is provided with a second screw plate, the first screw plate and the second screw plate being screwed to the upper and lower ends of the mounting screw plate respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In this invention, the movement of the collar driven by the electric telescopic rod enables multi-angle bending at the top of the telescopic hose, allowing the sampling head to flexibly adjust the sampling angle as needed to adapt to different sampling scenarios and requirements. Furthermore, the electric telescopic rod can precisely control its extension and retraction length and angle, thereby achieving precise adjustment of the sampling angle and improving the accuracy and reliability of sampling. At the same time, the automatic extension and retraction of the electric telescopic rod eliminates the need for operators to manually adjust the angle of the sampling head, improving the convenience and efficiency of operation.

[0014] In this invention, by rotating the air intake tube, telescopic hose, and top plate through a rotating mechanism, the sampling head can be rotated at multiple angles in three-dimensional space, thereby expanding the sampling range and enabling more comprehensive collection of air samples from different areas. Furthermore, the rotating mechanism can quickly adjust the sampling head to the required sampling angle, reducing manual intervention and improving the automation level of sampling. At the same time, the rotating mechanism, through a motor, can precisely control the horizontal rotation angle of the telescopic hose, thereby avoiding the influence of human factors on the sampling angle and improving the sampling accuracy.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: an air sampler sampling head with automatic angle adjustment, including a telescopic hose 1, a collar 2 sleeved on one side of the outer wall of the telescopic hose 1, an electric telescopic rod 3 screwed to the bottom side of the collar 2, the bottom end of the electric telescopic rod 3 screwed to the top side of the top plate 4, a base 5 rotatably connected to the bottom end of the top plate 4, a rotating mechanism 6 screwed to one side of the bottom wall of the base 5, a filtering mechanism 7 screwed to the bottom of the base 5, and a connecting pipe 8 screwed to the bottom of the filtering mechanism 7.

[0022] In this embodiment, as Figure 1 and Figure 2As shown, the bottom end of the telescopic hose 1 is equipped with an air intake pipe 101, which vertically penetrates the interior of the top plate 4 and the base 5. It should be noted that the operator can first assemble the telescopic hose 1, top plate 4, base 5, filter mechanism 7, and connecting pipe 8 in sequence, and then install the entire sampling head assembly at the sampler via the connecting pipe 8. Simultaneously, the operator can start the sampler to perform air sampling. During this process, the telescopic hose 1 can draw air from the sampling area into its interior, and under the action of the sampler, the air is drawn downwards into the air intake pipe 101. Because the air intake pipe 101 vertically penetrates the interior of the top plate 4 and the base 5, the gas will flow downwards along the air intake pipe. The pipe 101 flows through the top plate 4 and the base 5, and reaches the filter mechanism 7 for impurity filtration, so that the pure gas can continue to be delivered downward to the collection area inside the sampler. In actual use, the telescopic hose 1 can be extended or shortened to a certain extent, so that the sampling head can adapt to different sampling distance and angle requirements under the action of the adjustment mechanism. The air intake pipe 101 runs vertically through the interior of the top plate 4 and the base 5, which further enhances the structural stability of the entire sampling head and facilitates the flow of gas. The setting of the air intake pipe 101 can provide a flow channel to ensure that the sampled air can enter and be delivered quickly and smoothly, thereby improving the sampling efficiency.

[0023] In this embodiment, as Figure 1 and Figure 2 As shown, the collar 2 and the electric telescopic rod 3 together constitute the adjustment mechanism. It should be noted that after the operator completes the assembly and connection between the sampling head component and the sampler, the operator can adjust the sampling angle of the telescopic hose 1 according to the area to be sampled. Specifically, the electric telescopic rod 3 is activated by an external controller, causing its drive end to extend and retract obliquely, moving the collar 2 connected to it. This causes the top of the telescopic hose 1, which is fitted inside the collar 2, to bend at multiple angles. In actual use, by driving the collar 2 with the electric telescopic rod 3, multiple angle bends can be achieved at the top of the telescopic hose 1, allowing the sampling head to flexibly adjust the sampling angle as needed to adapt to different sampling scenarios and requirements. Furthermore, the electric telescopic rod 3 can precisely control its extension and retraction length and angle, thereby achieving precise adjustment of the sampling angle, improving the accuracy and reliability of sampling. Simultaneously, the automatic extension and retraction of the electric telescopic rod 3 eliminates the need for manual adjustment of the sampling head angle by the operator, improving operational convenience and efficiency.

[0024] In this embodiment, as Figure 2 and Figure 3As shown, the rotating mechanism 6 includes a motor 601, a rotating shaft 602, a driving gear 603, and a driven gear ring 604. The bottom end of the motor 601 is screwed to one side of the bottom wall of the base 5. The output end of the motor 601 is inserted into the driving gear 603, and the driven gear ring 604 meshes with one side of the driving gear 603. The driven gear ring 604 is sleeved on the top outer wall of the air intake pipe 101. It should be noted that when the operator needs to sample the air in different areas, the motor 601 can be started to rotate its output end, which will drive the rotating shaft 602 inserted with it to rotate together. At the same time, the driving gear 603 sleeved on the top outer wall of the rotating shaft 602 will be driven to rotate, and the driven gear ring 604 meshed on one side of it will also rotate. The air intake tube 101, which is sleeved on the inner wall of the driven toothed ring 604, rotates synchronously, thereby allowing the telescopic hose 1 at the top of the air intake tube 101 and the top plate 4 sleeved with it to adjust their direction automatically. In actual use, by rotating the air intake tube 101, the telescopic hose 1, and the top plate 4 through the rotating mechanism 6, the sampling head can be rotated at multiple angles in three-dimensional space, thereby expanding the sampling range and enabling more comprehensive collection of air samples from different areas. The rotating mechanism 6 can also quickly adjust the sampling head to the required sampling angle, reducing manual intervention and improving the automation of sampling. At the same time, the rotating mechanism 6, through the motor 601, can precisely control the horizontal rotation angle of the telescopic hose 1, thereby avoiding the influence of human factors on the sampling angle and improving the sampling accuracy.

[0025] In this embodiment, as Figure 2 and Figure 3 As shown, the bottom outer edge of the top plate 4 is provided with a protruding ring 401, and the top outer edge of the base 5 is provided with a rotating groove 501. The protruding ring 401 and the rotating groove 501 form a rotatable connection. It should be noted that when the operator drives the air intake pipe 101 and the telescopic hose 1 at its top end to rotate by activating the rotating mechanism 6, the top plate 4, which is sleeved on the outer wall of the air intake pipe 101, will also be rotated together. During this period, the protruding ring 401 at the bottom outer edge of the top plate 4 will rotate in contact with the inside of the rotating groove 501, thereby realizing the telescopic hose 1... The electric telescopic rod 3, screwed to one side of the top plate 4, can simultaneously adjust its direction. In actual use, the cooperation between the convex ring 401 and the rotating groove 501 can make the connection between the top plate 4 and the base 5 tighter. By providing a directional rotating track, it can reduce the shaking or instability of the top plate 4 and the telescopic hose 1 during rotation, thereby increasing the stability during the entire sampling head adjustment. In addition, the design of the convex ring 401 and the rotating groove 501 also reduces friction and wear between components, thereby improving the reliability and service life of the device.

[0026] In this embodiment, as Figure 4As shown, the filter mechanism 7 includes a mounting screw plate 701, a fixing sleeve 702, and a filter element 703. The mounting screw plate 701 is located on the annular outer wall of the fixing sleeve 702, and the filter element 703 is located inside the fixing sleeve 702. It should be noted that the operator can complete the assembly connection between the filter mechanism 7, the base 5, and the connecting pipe 8 through the mounting screw plate 701, so that the sampling head component and the sampler are assembled. At this time, the air intake pipe 101 located at the bottom of the telescopic hose 1 will pass through the top plate 4 and the base 5 in sequence, and finally reach the top opening of the filter mechanism 7. When the sampling gas flows through the telescopic hose 1 and the air intake pipe 101 through the filter mechanism 7, it will directly react with the filter element 703 located inside the fixing sleeve 702. When the filter element 703 comes into contact with the sampler, impurities in the gas are filtered and intercepted on the surface of the filter element 703, while the pure gas portion passes through the filter element 703 and continues to be conveyed downwards. In actual use, the filter element 703 in the filtration mechanism 7 can effectively intercept tiny particles in the air, enabling the sampler to collect the target gas more accurately and improving the sampling accuracy. The filtration mechanism 7 can also block dust, water vapor, and other substances in the air, thereby protecting the internal components of the sampler from wear and corrosion and extending its service life. At the same time, the installation screw plate 701 in the filtration mechanism 7 makes the entire filtration mechanism 7 easier to disassemble and assemble, thus facilitating the replacement of the filter element 703 and ensuring its filtration effect.

[0027] In this embodiment, as Figure 3 and Figure 4 As shown, the annular outer wall of the base 5 is provided with a first screw plate 502, and the annular outer wall of the connecting pipe 8 is provided with a second screw plate 801. The first screw plate 502 and the second screw plate 801 are respectively screwed to the upper and lower ends of the mounting screw plate 701. It should be noted that when the operator needs to assemble the various sampling head components, the base 5, the filter mechanism 7, and the connecting pipe 8 can be stacked together in sequence so that the first screw plate 502, the mounting screw plate 701, and the second screw plate 801 can fit together tightly. At the same time, the operator can use fastening screws to penetrate the screw holes opened on the surfaces of the first screw plate 502, the mounting screw plate 701, and the second screw plate 801 from top to bottom. Internally, the screws are tightened to complete the threaded installation between the base 5, the filter mechanism 7, and the connecting pipe 8. In actual use, the connection between the base 5, the filter mechanism 7, and the connecting pipe 8 is made tighter and more secure through the screw connection of the first screw plate 502 and the second screw plate 801. This facilitates on-site assembly and disassembly by operators. The screw connection also increases the overall stability of the sampling head, reducing loosening or shaking during use, thereby improving the accuracy and reliability of sampling. At the same time, when it is necessary to maintain or replace parts of the sampling head, it is easy to operate by simply unscrewing the corresponding fastening screws, reducing maintenance time and workload.

[0028] The usage method and advantages of this utility model: The automatic angle-adjustable air sampler sampling head operates as follows:

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, during the initial assembly of the various sampling head components, the operator can first stack the base 5, filter mechanism 7, and connecting pipe 8 together in sequence, ensuring that the first screw plate 502, mounting screw plate 701, and second screw plate 801 fit tightly together. Simultaneously, the operator can use fastening screws to penetrate the screw holes on the surfaces of the first screw plate 502, mounting screw plate 701, and second screw plate 801 from top to bottom and tighten them, thereby completing the connection between the base 5, filter mechanism 7, and connecting pipe 8. The threaded installation is followed by the installation of the connecting pipe 8 at the sampler. Before sampling, the operator can start the motor 601, causing its output end to rotate and drive the shaft 602 connected to it to rotate. At the same time, the drive gear 603, which is sleeved on the outer wall of the top of the shaft 602, will be driven to rotate, causing the driven gear ring 604 meshed on one side and the air intake pipe 101 sleeved on the inner wall of the driven gear ring 604 to rotate synchronously, thereby causing the telescopic valve at the top of the air intake pipe 101 to extend. The flexible hose 1 and the top plate 4 connected to it automatically adjust to the designated area. Then, the electric telescopic rod 3 is activated by the external controller, causing its drive end to extend and retract obliquely, and moving the collar 2 connected to it. This causes the top of the flexible hose 1, which is connected to the collar 2, to bend to a suitable angle. At the same time, the operator can start the sampler to sample the air. During this process, the flexible hose 1 can draw air from the sampling area into its interior, and under the action of the sampler, the air is input downward into the air intake pipe 101. Since the air intake pipe 101 is vertically inserted into the interior of the top plate 4 and the base 5, the gas will flow through the pipe of the air intake pipe 101, through the top plate 4 and the base 5, and reach the filter mechanism 7. It will then come into contact with the filter element 703 inside the fixed housing 702, so that the impurity particles in the gas are filtered and intercepted on the surface of the filter element 703, which is convenient for separation and detection. The pure gas portion will pass through the filter element 703 and continue to be transported downward to the collection area inside the sampler.
