Description

Technical Field

[0001] This utility model relates to the field of aerosol collection technology, specifically to a detection device. Background Technology

[0002] As the importance of aerosols in airborne transmission becomes increasingly apparent, timely and accurate monitoring of potential airborne pathogens has become one of the key aspects of prevention and control measures.

[0003] Current methods for aerosol sampling and testing of air in testing locations primarily rely on manual operation. This involves personnel manually collecting air samples from the testing site and then transporting them to a laboratory for processing and testing. Because transportation takes time, this method not only reduces sampling efficiency but also increases operational complexity. Furthermore, during transportation, factors such as the sealing performance of the sample containers can lead to sample contamination, affecting the efficiency and accuracy of the testing.

[0004] Therefore, there is an urgent need for a detection device that integrates aerosol sampling, processing, and detection to reduce manpower requirements. Utility Model Content

[0005] In view of this, the present invention provides a detection device to address the problem that existing methods for aerosol sampling and detection of air in testing locations mainly rely on manual operation. This means that personnel need to manually collect air samples from the testing location and then transport them to a laboratory for processing and testing. Because transportation takes time, this detection method not only reduces sampling efficiency but also increases operational complexity. Furthermore, during transportation, factors such as the sealing performance of the sample container can lead to sample contamination, affecting the efficiency and accuracy of the detection.

[0006] This utility model provides a detection device, comprising:

[0007] Base;

[0008] A collection unit is connected to the base. The collection unit includes a first receiving cavity. The collection unit is used to draw outside air into the first receiving cavity to collect aerosols in the outside air and use them as samples.

[0009] A detection unit is connected to the base and is located on one side of the acquisition unit. The detection unit is used to detect the sample collected by the acquisition unit in order to detect the composition and content of aerosols in the outside air.

[0010] A driving unit is connected to the base and disposed on one side of the acquisition unit and / or the detection unit. The driving unit is used to drive the operation of the acquisition unit and / or the detection unit, and / or the driving unit is also used to drive the movement of the sample.

[0011] Beneficial Effects: By setting up collection and detection units, aerosols in the air can be collected to form samples, which can then be directly tested to understand the composition and content of aerosols in the air. This eliminates the need for previously collected aerosols to be sent to a laboratory for testing, avoiding sample contamination during transportation and thus improving the detection accuracy of the device. Furthermore, by incorporating a drive unit, which drives the collection and detection units and the movement of the samples, manual intervention is reduced, thereby improving the detection efficiency of the device and minimizing the time spent by collection personnel in the testing area, thus enhancing the protection of collection personnel.

[0012] In one optional implementation, the acquisition unit includes:

[0013] The acquisition structure includes a first receiving cavity and a first switch door. The first switch door has an open state that allows the first receiving cavity to communicate with the outside world, and a closed state that closes the first receiving cavity to the outside world.

[0014] A collection structure is provided on one side of the acquisition structure. The collection structure contains a collection component for collecting the sample. When the acquisition structure is in the open state, the collection structure is detached from the acquisition structure by the driving unit so that when the acquisition structure is in the closed state, external air can be driven through the collection component to collect aerosols from the external air to form the sample.

[0015] Beneficial effects: By designing a collection structure, ambient air is automatically drawn through the collection structure, where aerosols are collected and formed into samples. This eliminates the need for manual sample collection, reducing manpower and thus improving the sample collection efficiency of the detection device.

[0016] In one alternative implementation, the first switch door is hinged to the acquisition structure;

[0017] And / or, the acquisition structure is threadedly connected to the collection structure;

It is used to drive outside air through the collecting member so that the collecting member can collect aerosols from the outside air.

[0023] Beneficial effects: By defining multiple collection structures, multiple collection structures can collect aerosols from multiple points in the testing area, thereby improving the accuracy of the detection device in detecting the composition and content of aerosols in the testing area.

[0024] By setting up a storage structure and a driving structure, the driving structure can drive outside air through the collecting component, so that the collecting component can collect aerosols from the outside air.

A cross-section is taken along the axis perpendicular to the collecting structure, and the cross-section of the collecting structure is designated as a second cross-section. The length and width dimensions of the first cross-section are not less than the length and width dimensions of the second cross-section, respectively. When the first auxiliary structure is driven by the driving unit to be in the first state, the first auxiliary structure contacts the collecting structure disposed in the first receiving cavity, so as to push the collecting structure into the first receiving cavity.

[0030] Beneficial effects: By setting the first auxiliary structure, the driving unit can clamp the first auxiliary structure to push the collection structure, increasing the contact area between the driving unit and the collection structure, improving the reliability of the driving unit in pushing the collection structure into the first receiving cavity, thereby achieving the technical effect of improving the reliability of the detection device.

[0034] Beneficial effects: By setting up a second auxiliary structure and a detection structure, the composition and content of aerosols in the sample can be detected without sending the sample to the laboratory, thereby improving the automation and convenience of aerosol detection.

[0056] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0057] The following is combined with Figures 1 to 4 The following describes embodiments of the present invention.

[0058] According to an embodiment of the present invention, a detection device is provided, comprising:

[0059] Base 1;

[0060] The collection unit 2 is connected to the base 1. The collection unit 2 includes a first receiving cavity. The collection unit 2 is used to draw outside air into the first receiving cavity to collect aerosols in the outside air and use them as samples.

[0061] The detection unit 3 is connected to the base 1 and is located on one side of the collection unit 2. The detection unit 3 is used to detect the sample collected by the collection unit 2 in order to detect the composition and content of aerosols in the outside air.

[0062] The driving unit 4 is connected to the base 1 and is located on one side of the acquisition unit 2 and / or the detection unit 3. The driving unit 4 is used to drive the operation of the acquisition unit 2 and / or the detection unit 3, and / or the driving unit 4 is also used to drive the movement of the sample.

[0063] In the detection device of this embodiment, by setting up a collection unit 2 and a detection unit 3, it is possible to collect aerosols in the air to form a sample, and then directly detect the sample to understand the composition and content of aerosols in the air. This eliminates the need for sending collected aerosols to a laboratory for testing, as is done in related technologies, avoiding sample contamination during transportation and thus improving the detection accuracy of the device. Furthermore, by setting up a drive unit 4, which drives the operation of the collection unit 2 and the detection unit 3 and the movement of the sample, manual intervention is reduced, thereby improving the detection efficiency of the device and reducing the time spent by collection personnel in the testing area, thus enhancing the protection of collection personnel.

[0064] In this embodiment, the driving unit 4 is located on one side of the acquisition unit 2 and the detection unit 3. Of course, in other embodiments, depending on the design of the detection device, the driving unit 4 may be located only on one side of the acquisition unit 2 or only on one side of the detection unit 3. For example, the driving unit 4 may be located on the side of the acquisition unit 2 away from the detection unit 3, or the driving unit 4 may be located on the side of the detection unit 3 away from the acquisition unit 2.

[0065] Furthermore, the driving unit 4 is used to drive the acquisition unit 2 and the detection unit 3 to work, and to drive the movement of the sample, so as to reduce the involvement of the acquisition personnel and thus achieve the technical effect of protecting the acquisition personnel.

[0066] Of course, in other embodiments, depending on the design of the detection device, the driving unit 4 may be a combination of one or more schemes that drive the operation of the acquisition unit 2, drive the operation of the detection unit 3, and drive the movement of the sample, all of which are within the protection scope of this utility model.

[0067] In this embodiment, the external environment is the location to be inspected. Of course, in other embodiments, the specific location of the external environment may be adjusted depending on the application scenario of the detection device.

[0068] In addition, combined Figure 3 As shown, in this embodiment, the acquisition unit 2 includes:

[0069] The acquisition structure is provided with a first receiving cavity, and a first opening and closing door 203 is hinged to the acquisition structure. The first opening and closing door 203 has an open state that allows the first receiving cavity to communicate with the outside world, and a closed state that closes the first receiving cavity to the outside world.

[0070] The collection structure 202 is located on one side of the acquisition structure. The collection structure 202 contains a collection component for collecting samples. When the acquisition structure is in the open state, the drive unit 4 drives the collection structure 202 to be connected and disconnected from the acquisition structure so that when the acquisition structure is in the closed state, it can drive the outside air through the collection component and collect the aerosols of the outside air to form a sample.

[0071] By setting up a collection structure, ambient air can automatically pass through the collection structure 202, where aerosols from the ambient air are collected and formed into samples by the collecting components. Based on this, manual sample collection is unnecessary, reducing manpower and thus improving the sample collection efficiency of the detection device.

[0072] Of course, in other embodiments, the structure of the acquisition unit 2 may be adjusted according to the different designs of the detection device. For example, the acquisition unit 2 may only have a collection structure 202. By extending the time that the collection structure 202 is in the external environment, the external air can pass through the collection structure 202 to achieve the collection of aerosols in the external air by the collection structure 202.

[0073] It should be noted that when the collection structure 202 is not in use, it is kept in a sealed storage state by packaging and is not exposed. When the detection device is placed in the testing location, the collection structure 202 is taken out of the packaging, thereby achieving the technical effect of improving the detection accuracy of the detection device.

[0074] Furthermore, in this embodiment, the acquisition structure and the first switch door 203 are connected by a push-type latch, that is, combined with Figure 3 As shown, the left side of the acquisition structure is hinged to the left side of the first switch door 203, and the right side of the acquisition structure is connected to the right side of the first switch door 203 via a push-button latch. When the first switch door 203 is in the open state, pressing the first switch door 203 with the drive structure causes the first switch door 203 to rotate relative to the acquisition structure, thus closing the connection between the two structures. When the first switch door 203 needs to be in the open state, pressing the first switch door 203 with the drive structure causes it to rotate relative to the acquisition structure, thus opening the connection between the two structures. The push-button latch is a mature technology and will not be described in detail here.

[0075] As an alternative implementation, the connection between the acquisition structure and the first switch door 203 can be adjusted. For example, the left side of the acquisition structure can be connected to the left side of the first switch door 203 via a push-button latch, and the right side of the acquisition structure can be hinged to the right side of the first switch door 203. Alternatively, the connection between the acquisition structure and the first switch door 203 can be adjusted. As long as the first switch door 203 can be in an open or closed state, it is within the protection scope of this utility model.

[0076] Of course, in other embodiments, the connection between the acquisition structure and the first switch door 203 can be adjusted according to the design of the detection device. For example, the acquisition structure and the first switch door 203 may only be hinged. A handle is provided on the first switch door 203. When the first switch door 203 is in the open state, the drive unit 4 clamps the handle to drive the first switch door 203 to rotate relative to the acquisition structure, so that the first switch door 203 and the acquisition structure are in the closed state. When it is necessary for the first switch door 203 to be in the open state, the drive unit 4 clamps the handle to drive the first switch door 203 and the acquisition structure to be in the open state.

[0077] Alternatively, the first door 203 can be manually operated to be in an open or closed state.

[0078] In addition, combined Figure 4 As shown, in this embodiment, the acquisition structure includes:

[0079] The storage structure 201 includes a first receiving cavity, and a first opening and closing door 203 is hinged to the storage structure 201. The connection method between the storage structure 201 and the base 1 is not limited. It can be a fixed connection or a detachable connection. Fixed connection and detachable connection are mature technologies and will not be described in detail here.

[0080] The driving structure is connected to the storage structure 201. One end of the driving structure is connected to the outside, and the other end of the driving structure is connected to the first receiving cavity. It is used to drive the outside air through the collector so that the collector can collect the aerosols from the outside air.

[0081] The housing structure 201 is a shell structure, and the driving structure is a vacuum pump. The air inlet of the vacuum pump is connected to the outside, and the air outlet of the vacuum pump is connected to the collecting component. By setting up the housing structure 201 and the driving structure, the driving structure can drive the outside air through the collecting component, so that the collecting component can collect aerosols from the outside air.

[0082] Specifically, the inner wall of the first receiving cavity is provided with a first thread, and the outer wall of the collecting structure 202 is provided with a second thread that mates with the first thread. Through the threaded connection between the first and second threads—that is, the second thread completely passes through the first thread—the smooth outer wall of the collecting structure 202 corresponds to the first thread, thus achieving a threaded connection between the first receiving cavity and the collecting structure 202. Based on this, the technical effect of improving the reliability of the connection between the collecting structure and the collecting structure 202 is achieved.

[0083] Alternatively, the acquisition structure and the collection structure 202 can be connected by a snap-fit ​​connection. Snap-fit ​​connection is a mature technology and will not be elaborated upon here.

[0084] Of course, in other embodiments, depending on the design of the detection device, the specific structure of the driving structure can be adjusted. For example, the driving structure can be a syringe, which draws in outside air and injects it into the collection device.

[0085] In other embodiments, the specific type of the storage structure 201 may be adjusted depending on the design of the detection device; for example, the storage structure 201 may be a box structure.

[0086] In addition, combined Figure 4As shown, in this embodiment, multiple collection structures 202 are provided. Based on this, multiple collection structures 202 can collect aerosols from multiple points in the area to be tested, thereby improving the accuracy of the detection device in detecting the aerosol composition and content of the area to be tested. The number of collection structures 202 is not specifically limited and can be adjusted according to actual needs.

[0087] Furthermore, combined Figure 4 As shown, in this embodiment, the acquisition unit 2 includes:

[0088] The support structure 204 has at least one receiving hole for receiving the collection structure 202.

[0089] Among them, the support structure 204 is a support frame, and the number of accommodating holes corresponds one-to-one with the number of collection structures 202, which can achieve the technical effect of improving the support stability of the collection structure 202, thereby achieving the technical effect of improving the reliability of the detection device.

[0090] As an alternative implementation, the support structure 204 may have only one receiving hole, through which multiple collection structures 202 can be accommodated. Alternatively, the type of support structure 204 may be adjusted, for example, the support structure 204 may be a box structure.

[0091] Of course, in other embodiments, depending on the design of the detection device, only one collection structure 202 is provided.

[0092] Alternatively, the acquisition unit 2 may not include the support structure 204.

[0093] In this embodiment, the collecting structure 202 is a hollow cylindrical structure, the collecting element is a filter membrane, and the inner diameter of the hollow cylindrical structure is equal to the outer diameter of the filter membrane, so that the filter membrane can be snapped into the hollow cylindrical structure. Preferably, the filter membrane is a microporous filter membrane.

[0094] Of course, in other embodiments, the type of collection structure 202 and collection element can be adjusted according to the design of the detection device. For example, the collection structure 202 is a porous structure and the collection element is a glass fiber filter membrane.

[0095] As an alternative implementation, it is also possible to limit the first opening and closing door 203 to be hinged to the collection structure, the collection structure to be threadedly connected to the collecting structure 202, the collecting element to be a microporous filter membrane, the collecting structure 202 to be provided in multiple ways, and the collection structure to include one or more of the structures of the storage structure 201 and the driving structure, all of which are within the protection scope of this utility model.

[0096] In addition, combined Figure 4As shown, in this embodiment, the detection device includes:

[0097] The first auxiliary structure 5 is movably connected to the base 1. The first auxiliary structure 5 has a first state separated from the base 1 and a second state placed on the base 1. A cross section is made along the axis perpendicular to the first auxiliary structure 5, and the cross section of the first auxiliary structure 5 is designated as the first cross section. A cross section is made along the axis perpendicular to the collecting structure 202, and the cross section of the collecting structure 202 is designated as the second cross section. The length and width dimensions of the first cross section are not less than the length and width dimensions of the second cross section. When the first auxiliary structure 5 is driven by the driving unit 4 to be in the first state, the first auxiliary structure 5 contacts the collecting structure 202 located in the first receiving cavity, so as to push the collecting structure 202 into the first receiving cavity.

[0098] By setting the first auxiliary structure 5, the driving unit 4 can clamp the first auxiliary structure 5 to push the collection structure 202, thereby increasing the contact area between the driving unit 4 and the collection structure 202 and improving the reliability of the driving unit 4 in pushing the collection structure 202 into the first receiving cavity, thus achieving the technical effect of improving the reliability of the detection device.

[0099] When the second thread completely passes through the first thread, the drive unit 4 clamps the first auxiliary structure 5 so as to push the collecting structure 202 into the first receiving cavity through the first auxiliary structure 5.

[0100] Specifically, the base 1 is provided with a groove, the groove being matched with the size of the first auxiliary structure 5, so that when the first auxiliary structure 5 is in the second state, the first auxiliary structure 5 is located in the groove, thereby achieving the technical effect of improving the positional reliability of the first auxiliary structure 5.

[0101] As an alternative implementation, the base 1 may not have a groove, and the first auxiliary structure 5 may be placed directly on the surface of the base 1. Alternatively, the dimensions of the first auxiliary structure 5 may be adjusted, as long as the dimensions of the first auxiliary structure 5 can be adjusted to push the collecting structure 202 into the first receiving cavity, all of which are within the protection scope of this utility model.

[0102] Of course, in other embodiments, depending on the design of the detection device, the timing of the drive unit 4 pushing the collection structure 202 through the first auxiliary structure 5 can be adjusted.

[0103] In other embodiments, depending on the design of the detection device, the detection device does not include the first auxiliary structure 5. Alternatively, the timing of the first auxiliary structure 5 pushing the collecting structure 202 into the first receiving cavity may be adjusted. For example, after the driving unit 4 places the collecting structure 202 into the first receiving cavity, the first auxiliary structure 5 pushes the collecting structure 202 into the first receiving cavity.

[0104] In addition, combined Figure 4 As shown, in this embodiment, the detection unit 3 includes:

[0105] The second auxiliary structure 301 is located on one side of the acquisition unit 2 and is used to hold the sample;

[0106] The detection structure 302 is located on the side of the second auxiliary structure 301 away from the acquisition unit 2, and is used to detect the composition and content of aerosols in the sample in the second auxiliary structure 301.

[0107] The second auxiliary structure 301 is a PCR kit, and the detection structure 302 is a PCR (Polymerase Chain Reaction) instrument. By setting the second auxiliary structure 301 and the detection structure 302, the composition and content of aerosols in the sample can be detected without sending the sample to the laboratory, thereby improving the automation, accuracy, and convenience of aerosol detection.

[0108] Preferably, the detection unit 3 includes a frame for supporting the second auxiliary structure 301, thereby improving the positional reliability of the second auxiliary structure 301.

[0109] Furthermore, in this embodiment, multiple second auxiliary structures 301 are provided, for example, corresponding one-to-one with the collection structures 202, so as to facilitate the detection of the collection items in the multiple collection structures 202.

[0110] In this process, after the drive unit 4 places the collection structure 202 from the first receiving cavity into the support structure 204, the collector places the collection component in the collection structure 202 into the second auxiliary structure 301.

[0111] Of course, in other embodiments, the specific types of the second auxiliary structure 301 and the detection structure 302 are limited according to the different designs of the detection device. For example, if the collector method is used for detection, the second auxiliary structure 301 is a carrier dish and the detection structure 302 is a culture medium, all of which are within the protection scope of this utility model.

[0112] Alternatively, the second auxiliary structure 301 may not be mounted on the frame but may be mounted directly on the base 1, all of which are within the protection scope of this utility model.

[0113] In other embodiments, depending on the design of the detection device, the position between the second auxiliary structure 301 and the detection structure 302 is adjusted. For example, the detection structure 302 is located on the side of the second auxiliary structure 301 closer to the acquisition unit 2. Compared to other embodiments, this embodiment limits the detection structure 302 to the side of the second auxiliary structure 301 away from the acquisition unit 2, and places the collection structure 202 and the second auxiliary structure 301 close together, shortening the distance between them. This facilitates the collection personnel in quickly placing the collected items in the collection structure 202 into the second auxiliary structure 301, thereby improving the detection efficiency of the detection device.

[0114] In addition, combined Figure 1 As shown, in this embodiment, the detection device includes:

[0115] The housing 6 includes a second receiving cavity. The housing 6 is provided with a second switch door 8, which is used to adjust the connection or closure of the second receiving cavity with the outside. The second receiving cavity is used to accommodate the base 1, the acquisition unit 2, the detection unit 3 and the drive unit 4.

[0116] The moving unit 7 is located on the housing 6 and is used to drive the movement of the housing 6 by external force.

[0117] By setting up the housing 6 and the moving unit 7, the housing 6 can protect the base 1, the acquisition unit 2, the detection unit 3 and the driving unit 4, so as to prevent the detection device from being bumped and affected and thus achieve the technical effect of improving the reliability of the detection device.

[0118] The housing 6 measures 130cm*150cm*220cm, and the moving unit 7 is a self-locking universal wheel, which can improve the stability of the detection device's position without external force, thereby achieving the technical effect of improving the reliability of the detection device.

[0119] Of course, in other embodiments, the size of the housing 6 and the type of the moving unit 7 may be adjusted depending on the design of the detection device, for example, the moving unit 7 may be a regular caster wheel.

[0120] Alternatively, the detection device may not include the housing 6 and the moving unit 7.

[0121] In addition, the housing 6 includes a third receiving cavity, and the housing 6 is provided with a third switch door 9, which is used to adjust the communication or closure of the third receiving cavity with the outside world;

[0122] By setting up a third accommodating cavity, the materials required for testing can be stored for unforeseen needs, thereby improving the reliability of the testing device.

[0123] Of course, in other embodiments, depending on the design of the detection device, the housing 6 may not include a third receiving cavity.

[0124] As an alternative implementation, it is also possible to limit the housing 6 to include the third receiving cavity, or to limit the moving unit 7 to be a self-locking universal wheel, both of which are within the protection scope of this utility model.

[0125] In addition, combined Figure 4 As shown, in this embodiment, the driving unit 4 includes:

[0126] The robotic arm 401 is used to hold the sample and drive the operation of the acquisition unit 2 and the detection unit 3;

[0127] The third auxiliary structure 402 is connected to the robotic arm 401 and is used to drive the movement of the robotic arm 401.

[0128] Among them, robotic arm 401 is a six-axis robotic arm, and the third auxiliary structure 402 is a linear module. Both the six-axis robotic arm and the linear module are mature technologies, and will not be described in detail here.

[0129] Of course, in other embodiments, the structure of the drive unit 4 may be adjusted according to the design of the detection device. For example, the drive unit 4 may only include the robotic arm 401.

[0130] Furthermore, in this embodiment, the detection device includes a control unit, which is a central processing unit. The control unit is communicatively connected to the drive unit 4, the acquisition unit 2, and the detection unit 3, and is used to control the operation of the drive unit 4, the acquisition unit 2, and the detection unit 3. The communication connection and the control unit are mature structures and will not be described in detail here.

[0131] Furthermore, the drive unit 4 is communicatively connected to both the remote control and the button via the control unit. The button is located on the base 1 to facilitate the activation of the detection device in multiple ways. The remote control and button controls for the operation of the drive unit 4 are both mature technologies and will not be elaborated upon further here.

[0132] Of course, in other embodiments, only a remote control or only buttons may be provided. Alternatively, the type of control unit may be adjusted; for example, the control unit may be a host computer, meaning the host computer could be a PC.

[0133] Preferably, the housing 6 is made of a transparent material, such as glass. This enhances the visibility of the detection device, thereby improving the accuracy and ease of understanding of the detection process for the personnel involved.

[0134] Alternatively, the housing 6 can be made of transparent plastic or a non-transparent material, both of which are within the protection scope of this utility model.

[0135] The sampling and testing process of the detection device in this embodiment is as follows:

[0136] The collector pushes the housing 6 to place the detection device in the environment to be detected. The collector leaves the site and opens the second switch door 8. After a period of time, the housing 6 is filled with the gas of the environment to be detected.

[0137] The third auxiliary structure 402 drives the robotic arm 401 to move to the position of the collection structure. The robotic arm 401 presses the first switch door 203, which opens. Then, the third auxiliary structure 402 drives the robotic arm 401 to move to the position of the collection structure 202. The robotic arm 401 picks up a collection structure 202 and puts it into the first receiving cavity. Then, the robotic arm 401 drives the collection structure 202 to rotate, so that the collection structure 202 can be stably threadedly connected to the collection structure, so that the second thread after the threaded connection is placed inside the first thread. Then, the robotic arm 401 releases the collection structure 202.

[0138] The robotic arm 401 picks up the first auxiliary structure 5 and pushes the threaded collection structure 202 through the first auxiliary structure 5. That is, the first auxiliary structure 5 enables the collection structure 202 to move into the first receiving cavity, thereby improving the reliability of the connection between the collection structure 202 and the acquisition unit 2.

[0139] Next, the robotic arm 401 drives the first switch door 203 to close, and the drive structure drives the outside air to collect aerosols through the collection component. After a period of time, the robotic arm 401 drives the first switch door 203 to open, and after separating the collection structure 202 from the first receiving cavity, the collection structure 202 is placed on the support structure 204. At this time, the collection personnel enter the site, place the collection component in the collection structure 202 on the second auxiliary structure 301, and leave the site after placement.

[0140] Furthermore, the third auxiliary structure 402 drives the robotic arm 401 to be positioned at the second auxiliary structure 301, picks up the second auxiliary structure 301 and places it inside the detection structure 302. The detection structure 302 then detects the aerosol composition and content within the sample and outputs the detection results. The method of outputting the detection results varies depending on the type of detection structure 302. For example, the display screen on the detection structure 302 may show the aerosol composition and content, or the detection structure 302 may print out the aerosol composition and content; both are within the scope of protection of this utility model.

[0141] It can perform repeated multi-point detection, improving detection efficiency.

[0142] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
