Description

Technical Field

[0001] The present invention relates to the technical field of deodorization detection devices, and in particular to a deodorization function detection device for an intelligent toilet. Background Art

[0002] Smart toilets are the product of modern scientific and technological progress, aiming to improve people's life experience in the smart era. In addition to convenient functions such as water washing, warm air drying, and seat heating, existing smart toilets usually also need to have excellent deodorization functions. The quality of the deodorization function of smart toilets directly becomes the key technology for whether the smart toilet can impress users. Therefore, it is necessary to test the quality of the deodorization function of smart toilets.

[0003] The deodorization function of a smart toilet usually consists of three steps: extracting air, deodorizing the gas, and exhausting the air. When the prior art detects the deodorization function of a smart toilet, it usually only detects the odor content (usually methane or hydrogen sulfide gas) in the gas discharged after the smart toilet has treated the air. However, since the odor generated by the human body when using the toilet is often gradually released from the smart toilet to the entire space, the above detection data is difficult to be representative and cannot vividly and specifically show the deodorization efficiency of the detected smart toilet. In addition, when collecting the odor emitted by the smart toilet, the existing gas collection and detection device usually uses an air pump and an exhaust pipe to directly extract the surrounding air, so that most of the gas is subject to the force of flowing toward the exhaust pipe, affecting the efficiency of the detected smart toilet in extracting the surrounding air, and then affecting the deodorization efficiency of the detected smart toilet, causing the detection result to lose accuracy. Summary of the invention

[0004] In order to overcome the disadvantage that the existing detection device only detects the odor content in the gas discharged by the smart toilet after the gas is processed and is not representative, the present invention provides a deodorization function detection device for a smart toilet.

[0005] The technical solution of the present invention is: a deodorization function detection device for an intelligent toilet, comprising: a sealed room, a gas content analysis device is arranged outside the sealed room; a plurality of electric telescopic frames, all of which are arranged at intervals in transverse direction on the top plate inside the sealed room, and the electric telescopic frames are installed with a plurality of mounting plates distributed at intervals in longitudinal direction; a plurality of collecting tubes, which are respectively fixedly connected to adjacent mounting plates at intervals in transverse direction, and the collecting tubes are provided with a plurality of through holes distributed at intervals in circumferential direction; a ventilation head, the number of which is the same as the number of the collecting tubes, which are respectively fixedly connected to adjacent mounting plates, the ventilation head is connected to the adjacent collecting tubes, the ventilation head is connected to the gas content analysis device through a first hose, and a one-way valve is arranged in the first hose; a suction mechanism, the number of which is the same as the number of the collecting tubes, which are respectively arranged in adjacent collecting tubes, and are used to actively extract the gas around the adjacent collecting tubes, and at the same time actively transport the gas to the adjacent ventilation head.

[0006] Furthermore, the diameter of the collection tube is larger than the diameter of the ventilation head.

[0007] Furthermore, the vacuum mechanism includes: a collection plug, which is slidably and rotatably connected in the collection tube, and the collection plug is sealed and matched with the through hole on the adjacent collection tube; a connecting ring, which is fixed to the side of the ventilation head close to the collection plug, and the connecting ring is fixed to the collection plug, and the connecting ring is made of a flexible and stretchable material, and the ventilation head is connected with the adjacent collection tube through the adjacent connecting ring and the adjacent collection plug; a fixed base, which is fixed to the ventilation head, and the fixed base is rotatably connected with a sealing ring, and the sealing ring is rotatably connected to the adjacent collection tube, and the sealing ring is slidably connected to the adjacent collection plug; a driving component, the number of which is the same as the number of the collection tubes, and they are respectively arranged outside the adjacent collection tubes, and are used to drive the adjacent collection plugs to slide and rotate relative to the adjacent collection tubes.

[0008] Furthermore, a sealing member is fixedly connected to one side of the collecting plug close to the fixed base, the sealing member is squeezed and fitted with the adjacent fixed base, the sealing member is a flexible member, and the thickness of the sealing member close to the axis of the adjacent collecting tube is smaller than the thickness of the sealing member away from the axis of the adjacent collecting tube.

[0009] Furthermore, the driving assembly includes: a micro motor fixedly connected to the collecting tube, the collecting tube is rotatably connected to a spline gear, the output shaft of the micro motor is meshed with the adjacent spline gear through a transmission gear, the spline gear is spline-connected to the adjacent collecting plug; a driving telescopic rod fixedly connected to the adjacent mounting plate, the output shaft of the driving telescopic rod is fixedly connected to a connecting ring, and the connecting ring is rotatably connected to the adjacent collecting plug.

[0010] Furthermore, it also includes: ventilation pieces, the number of which is the same as that of the collecting tubes, the ventilation pieces are fixedly connected to the adjacent fixed bases, the fixed bases are provided with ventilation holes and connecting holes distributed circumferentially, and the ventilation holes are connected with the adjacent ventilation pieces through the connecting holes.

[0011] Furthermore, the angle between the axis of the vent hole and the surface of the adjacent collection plug facing the adjacent fixed base is less than 60°, and the axis of the vent hole gradually inclines toward the side away from the axis of the fixed base from the adjacent fixed base to the adjacent ventilation head.

[0012] Furthermore, the sealing member is provided with circumferentially spaced protrusions on one side facing the adjacent fixed base, and the protrusions are used to guide the gas ejected from the adjacent vent holes through their own curved surfaces.

[0013] Furthermore, it also includes: a partition, fixedly connected to the upper part of the sealed room, used to separate the sealed room into two upper and lower chambers; a sealed door, the number of which is the same as the number of the electric telescopic frames, installed in the partition, used to control the upper and lower chambers to be connected to or isolated from each other.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: 1. The present invention achieves the effect of sampling gases at multiple different positions in the sealed room at the same time, making the sampling results more representative. At the same time, when sampling is not performed, the mounting plate and the collection tube are moved to the corner position by using an electric telescopic frame to avoid the complex space structure in the sealed room causing the odor to be unable to diffuse freely.

[0016] 2. The present invention utilizes a collection tube and a collection plug to slowly and massively extract surrounding air. By collecting a large number of samples, the accuracy of the collected data is ensured while reducing the effect of the surrounding air flowing together when the air is extracted, thereby preventing the suction action from affecting the actual deodorization efficiency of the smart toilet, thereby avoiding distortion of the detection results.

[0017] 3. The present invention ventilates the collection tube through the vent piece, and completely passes the residual gas in the collection tube into the vent head and the gas content analysis device, thereby increasing the accuracy of single collection data and avoiding the influence of residual gas on the next detection.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0028] A deodorization function detection device for smart toilets, referring to Figure 1-Figure 5, including: a sealed house 1, a gas content analysis device is arranged outside the sealed house 1; a plurality of electric telescopic frames 2, all of which are arranged at the top plate of the sealed house 1 at transverse intervals, and the electric telescopic frames 2 are installed with a plurality of mounting plates 3 distributed at longitudinal intervals; a plurality of collecting tubes 4, which are fixedly connected to adjacent mounting plates 3 at transverse intervals, and the collecting tubes 4 are provided with a plurality of through holes distributed at circumferential intervals; a ventilation head 5, the number of which is the same as the number of collecting tubes 4, which are respectively fixedly connected to adjacent mounting plates 3, the ventilation head 5 is connected to the adjacent collecting tubes 4, the ventilation head 5 is connected to the gas content analysis device through a first hose, and a one-way valve is arranged in the first hose; a suction mechanism, the number of which is the same as the number of collecting tubes 4, which are respectively arranged in adjacent collecting tubes 4, and are used to actively extract the gas around the adjacent collecting tubes 4, and at the same time actively transport the gas to the adjacent ventilation head 5.

[0029] The above scheme aims to solve the problem that the existing detection device only detects the odor content in the gas discharged after the smart toilet treats the gas, resulting in the problem that the detection result is not representative. The sealed room 1 includes at least one sealed door, which is convenient for the staff to enter and exit the sealed room 1 and to replace the air in the sealed room 1. The sealed room 1 is equipped with a mounting seat 101, a control terminal 102, an air supply device 103, an exhaust device 104 and a gas content analysis device. The air supply device 103, the exhaust device 104, the electric telescopic frame 2, the exhaust mechanism and the gas content analysis device are all connected to the control terminal 102. The terminal 102 is electrically connected, wherein the mounting base 101 is used for loading and unloading the smart toilet, ensuring that the flushing pipe of the smart toilet is connected to the outside world, thereby ensuring that the detection environment is the same as the user's toilet environment, and the air supply device 103 and the exhaust device 104 cooperate to replace the air in the sealed room 1, and then after each detection is completed, the air in the sealed room 1 is completely exhausted to ensure the accuracy of the detection results when multiple smart toilets are continuously tested, and the gas content analysis device is used to accurately detect the content of hydrogen sulfide in the collected gas after all the ventilation heads 5 have collected the gas.

[0030] The workflow of the above scheme is as follows: the staff first opens the sealed door of the sealed room 1 and installs the toilet to be tested on the mounting seat 101, and then the staff puts an odor source into the smart toilet (it can be a porous material that absorbs a certain concentration of hydrogen sulfide, or a certain amount of hydrogen sulfide gas can be filled in a test tube, and then the hydrogen sulfide gas is gradually diffused outward from a small diameter air duct. No matter which method is used, it is necessary to ensure that the total amount of hydrogen sulfide contained in the odor source used in all detection processes is always consistent to ensure that all experiments have the same standard). The odor source will slowly volatilize the hydrogen sulfide gas within a certain period of time (for example, it will continuously release hydrogen sulfide gas within 10 minutes, and after a certain period of time, the hydrogen sulfide in the odor source will be completely consumed and will no longer release hydrogen sulfide gas). Then the staff starts the deodorization function of the smart toilet, leaves the sealed room 1 and closes the sealed door of the sealed room 1.

[0031] After leaving the sealed room 1, the staff controls all the electric telescopic frames 2 to extend downward at a fixed time through the control terminal 102. At this time, all the mounting plates 3 are evenly distributed in the sealed room 1. By making all the collecting tubes 4 cooperate with each other, the gas in various places in the sealed room 1 is sucked at the same time, thereby ensuring that the collected gas is the sum of the gas in various places in the entire space in the sealed room 1, so as to enhance the representativeness of the experimental data. The staff controls all the exhaust mechanisms through the control terminal 102 to extract a certain amount of gas into the adjacent collecting tubes 4. The extracted gas flows to the gas content analysis device through the adjacent collecting tubes 4 and the adjacent ventilation heads 5. After the gas content analysis device detects the hydrogen sulfide content of the gas extracted by all the ventilation heads 5 in turn (or collects the gas extracted by all the ventilation heads 5 together and then detects these gases together), the gas content analysis device discharges the gas after the detection to the outside of the sealed room 1 and transmits the data to the control terminal 102. After the control terminal 102 collects the data, it draws the deodorization efficiency curve of the smart toilet according to the data. After each gas extraction, the staff must close the exhaust mechanism through the control terminal 102, and control the electric telescopic frame 2 to drive the collection tube 4 and the adjacent ventilation head 5 to retract and reset upward to avoid the electric telescopic frame 2 and other components affecting the uniform flow of hydrogen sulfide in the sealed room 1. After a certain period of time (for example, after 20 minutes), after the staff finally collects the gas, they control the electric telescopic frame 2 and other components to reset through the control terminal 102, and directly open the air supply device 103 and the exhaust device 104 through the control terminal 102. The air supply device 103 supplies air to the sealed room 1, and the exhaust device 104 exhausts the air in the sealed room 1 to the outside. The air supply device 103 and the exhaust device 104 work together to exhaust and replace the gas in the sealed room 1, so as to avoid the residual hydrogen sulfide affecting the accuracy of the detection of other smart toilets.

[0032] Further, see Figure 4 and Figure 5 , the diameter of the collecting tube 4 is greater than the diameter of the ventilation head 5.

[0033] In the above scheme, by increasing the diameter of the collecting tube 4, when the same amount of gas is extracted through the vent head 5 (assuming that the diameter of the vent head 5 remains unchanged, the more air the vent head 5 extracts, the faster the gas flows at the vent head 5), the air flow rate at the through hole on the collecting tube 4 is less than the air flow rate at the vent head 5, thereby reducing the impact of the vent head 5 on the overall flow of air in the sealed house 1 when extracting air, avoiding most of the gas from gathering at the adjacent collecting tube 4, thereby avoiding affecting the deodorization efficiency of the tested smart toilet, and the larger the diameter of the collecting tube 4, it is easier to collect more gas at a single time under the premise of reducing the surrounding air flow driven by the collecting tube 4, so as to enhance the representativeness of the experimental data.

[0034] Further, see Figure 4-Figure 8 The exhaust mechanism includes: a collection plug 6, which is slidably and rotatably connected to the collection tube 4, and the collection plug 6 is sealed and matched with the through hole on the adjacent collection tube 4; a connecting ring 51, which is fixed to the side of the ventilation head 5 close to the collection plug 6, the connecting ring 51 is fixed to the collection plug 6, and the connecting ring 51 is made of a flexible and stretchable material. The ventilation head 5 is connected to the adjacent collection tube 4 through the adjacent connecting ring 51 and the adjacent collection plug 6; a fixed base 7, which is fixed to the ventilation head 5, and the fixed base 7 is rotatably connected to a sealing ring 8, which is rotatably connected to the adjacent collection tube 4 and slidably connected to the adjacent collection plug 6; a driving component, the number of which is the same as the number of the collection tubes 4, and is respectively arranged outside the adjacent collection tubes 4, for driving the adjacent collection plugs 6 to slide and rotate relative to the adjacent collection tubes 4.

[0035] In the above scheme, the connection between the collection plug 6, the fixed base 7, the sealing ring 8 and the collection tube 4 is a sealed connection. The one-way valve at the connection between the vent head 5 and the gas content analysis device only allows the adjacent gas to flow from the vent head 5 through the first hose to the gas content analysis device. The connecting ring 51 is made of a flexible and stretchable material. Figure 5 For example ( Figure 5 When the collecting plug 6 slides from front to back, the connecting ring 51 is gradually stretched, and when the collecting plug 6 moves from back to front, the connecting ring 51 gradually returns to its original state. The driving component is electrically connected to the control terminal 102 to Figure 5 For example, the collection plug 6, the fixed base 7, the sealing ring 8 and the collection tube 4 together form a vacuum chamber. Figure 5 The middle is the placement state of the device when it is not in use (or the state when it has just been fully pumped out of air). At this time, the space occupied by the device is small, which is convenient for placing or moving the device.

[0036] by Figure 5Taking the collection tube 4 and the collection plug 6 as an example, the working principle of the above scheme is as follows: when the control terminal 102 needs to control the vacuum mechanism to collect gas into the adjacent collection tube 4, it is first necessary to control the collection plug 6 to move backward by controlling the driving component. The collection plug 6 slides backward relative to the fixed base 7, the sealing ring 8, the collection tube 4 and the ventilation head 5, and the connecting ring 51 is stretched and deformed to reduce the volume in the vacuum chamber to 0. The gas volume in the vacuum chamber is 0 as the initial state. In the initial state, the collection plug 6 contacts the front side of the fixed base 7, the connecting ring 51 is in a stretched state, and the collection plug 6 does not block the through hole on the collection tube 4. When the electric telescopic frame 2 does not drive the collection tube 4 to move downward, the control terminal 102 moves the collection plug 6 to the initial state, and then controls the electric telescopic frame 2 to drive the collection tube 4 and the collection plug 6 to move to the location where they need to be used. When the electric telescopic frame 2 stops moving, the control terminal 102 controls the collection plug 6 to move forward by controlling the driving component. During the movement of the collection plug 6, The volume of the vacuum chamber gradually expands, and the vacuum chamber uses negative pressure to extract surrounding air through the through holes on the collection tube 4. When the collection plug 6 moves to the end of its stroke, the volume of the vacuum chamber reaches its limit state. Then the control terminal 102 controls the collection plug 6 to rotate a certain angle through the driving component. The collection plug 6 drives the sealing ring 8 to rotate relative to the fixed base 7, the collection tube 4 and the ventilation head 5. The connecting ring 51 is twisted and deformed, and the collection plug 6 blocks the through holes on the collection tube 4, so that the gas in the vacuum chamber cannot overflow. At this time, the control terminal 102 controls the collection plug 6 to move backward relative to the collection tube 4 through the driving component, squeezing the gas collected in the vacuum chamber. The gas in the vacuum chamber is discharged into the gas content analysis device through the connecting ring 51 and the ventilation head 5. When the collection plug 6 returns to its initial position, the control terminal 102 turns off the driving component, and controls the collection plug 6 to rotate and reset through the driving component. Then the control terminal 102 completes the gas collection process and controls the electric telescopic frame 2 to drive the adjacent components to move upward and reset.

[0037] Further, see Figure 5-Figure 8 A sealing member 61 is fixedly connected to one side of the collecting plug 6 close to the fixed base 7. The sealing member 61 is squeezed and fitted with the adjacent fixed base 7. The sealing member 61 is a flexible member, and its thickness on the side close to the axis of the adjacent collecting tube 4 is less than its thickness on the side away from the axis of the adjacent collecting tube 4.

[0038] In the above solution, the sealing member 61 is a flexible member that can be deformed by pressure. Figure 5 and Figure 7For example, the thickness of the sealing member 61 decreases gradually from the outside to the inside, and when the collecting plug 6 moves backward, that is, when the volume of the vacuum chamber gradually decreases, the outer side of the sealing member 61 first contacts the fixed base 7 and the sealing ring 8, and then the collecting plug 6 continues to move backward, and the sealing member 61 is deformed under the extrusion, and the contact area between the sealing member 61 and the fixed base 7 and the sealing ring 8 gradually increases, so that the remaining air in the vacuum chamber is discharged to the connecting ring 51, thereby increasing the cleanliness of the gas discharge in the vacuum chamber.

[0039] Further, see Figure 3-Figure 6 The driving component includes: a micro motor 9, which is fixed to the collection tube 4, and the collection tube 4 is rotatably connected to a spline gear 10. The output shaft of the micro motor 9 is meshed with the adjacent spline gear 10 through a transmission gear, and the spline gear 10 is spline-connected to the adjacent collection plug 6; a driving telescopic rod 11, which is fixed to the adjacent mounting plate 3, and the output shaft of the driving telescopic rod 11 is fixed to a connecting ring 12, and the connecting ring 12 is rotatably connected to the adjacent collection plug 6.

[0040] In the above scheme, the micro motor 9 and the driving telescopic rod 11 are both electrically connected to the control terminal 102. The micro motor 9 is used to drive the collection plug 6 to rotate through the transmission gear and the spline gear 10. The driving telescopic rod 11 is used to drive the adjacent collection plugs 6 to move forward or backward through the connecting ring 12. The driving telescopic rod 11 can be an electric telescopic rod or a hydraulic telescopic rod. One driving telescopic rod 11 can be used on the same mounting plate 3 for driving, or multiple driving telescopic rods 11 or a double-headed driving telescopic rod 11 can be used for driving. The two connecting rings 12 are driven by the adjacent driving telescopic rods 11 to move in opposite directions or back to back at the same time, so as to drive the two adjacent collection plugs 6 to move relative to the adjacent collection tubes 4 respectively.

[0041] Further, see Figure 4 , Figure 6-Figure 8 , and also includes: ventilation pieces 13, the number of which is the same as that of the collection tube 4, the ventilation pieces 13 are fixedly connected to the adjacent fixed base 7, the fixed base 7 is provided with circumferentially spaced ventilation holes 71 and connecting holes, the ventilation holes 71 are connected with the adjacent ventilation pieces 13 through the connecting holes.

[0042] In the above scheme, the ventilation piece 13 is connected with the gas supply device 103 through the ventilation pipe, and a one-way valve is provided at the connection point, which can only allow the gas in the gas supply device 103 to flow out into the ventilation piece 13. The ventilation hole 71 is a circular through hole, which is used to introduce the gas in the gas supply device 103 into the vacuum chamber, so that after the vacuum chamber discharges the gas in it into the collection plug 6 and the ventilation head 5 each time, the clean gas provided in the gas supply device 103 is used to push all the gas and hydrogen sulfide molecules remaining in the vacuum chamber into the collection plug 6, so as to prompt all the collected hydrogen sulfide gas to be discharged into the gas content analysis device through the collection plug 6, the connecting ring 51 and the ventilation head 5, so as to ensure the accuracy of the gas content detection this time, and avoid the hydrogen sulfide gas or hydrogen sulfide molecules from remaining in the vacuum chamber or the collection plug 6, the connecting ring 51 and the ventilation head 5, which affects the accuracy of the lower gas detection.

[0043] Further, see Figure 8 The angle between the axis of the vent hole 71 and the surface of the adjacent collecting plug 6 facing the adjacent fixed base 7 is less than 60°, and the axis of the vent hole 71 gradually inclines toward the side away from the axis of the fixed base 7 from the adjacent fixed base 7 to the adjacent ventilation head 5.

[0044] In the above scheme, the axis of the vent hole 71 is inclined toward the outside of the seal 61, and the angle between the axis of the vent hole 71 and the surface of the seal 61 is less than 60°, so that the gas ejected from the vent hole 71 is reflected by the surface of the seal 61 and effectively passes through the corners of the seal 61, the fixed base 7, the sealing ring 8 and the collection tube 4, thereby reducing the possibility of residual hydrogen sulfide molecules in the vacuum chamber and further increasing the accuracy of the experiment.

[0045] Further, see Figure 6-Figure 8 The sealing member 61 is provided with circumferentially spaced protrusions 62 on one side facing the adjacent fixed base 7 , and the protrusions 62 are used to guide the gas ejected from the adjacent vent hole 71 through its own curved surface.

[0046] In the above scheme, the protrusion 62 is only arranged at the edge of the outer side of the sealing member 61. By providing the protrusion 62, the gas ejected from the adjacent vent hole 71 is scattered in more directions through the scattering of the protrusion 62, thereby promoting the efficiency of the airflow in driving the surrounding gas flow. At the same time, the control terminal 102 can control the micro motor 9 to drive the collection plug 6 to rotate back and forth in a small amplitude when controlling the air supply device 103 to supply air to the ventilation member 13 and the vent hole 71. Under the premise of ensuring that the collection plug 6 will not release the blockage of the through hole on the adjacent collection tube 4, the scattering range and scattering intensity of the airflow passing through the protrusion 62 are increased to enhance the cleaning intensity of the gas for the residual gas.

[0047] Further, see Figure 2, and also includes: a partition 14, which is fixed to the upper part of the sealed house 1 and is used to separate the sealed house 1 into two upper and lower chambers; a sealed door 15, the number of which is the same as the number of the electric telescopic frame 2, which is installed in the partition 14 and is used to control the upper and lower chambers to be connected to or isolated from each other.

[0048] In the above scheme, the partition 14 and the sealing door 15 cooperate to divide the sealed room 1 into two upper and lower chambers. The upper chamber is used to store the electric telescopic frame 2 and other components during the non-detection period. The odor source in the smart toilet is diffused in the lower chamber, which is convenient for detecting the overall cleaning efficiency of the smart toilet on the odor in the lower chamber. The exhaust device 104 is located in the upper chamber, and the sealing door 15 is electrically connected to the control terminal 102. During the detection process, when the collection tube 4 needs to collect gas, the control terminal 102 controls the sealing door 15 to open. When the collection tube 4 has collected the gas, After the control terminal 102 controls all the electric telescopic frames 2 to drive all the collecting tubes 4 to move upward and reset, the control terminal 102 controls the sealing door 15 to close, so that the upper and lower chambers are isolated from each other. At this time, the control terminal 102 opens the exhaust device 104, and the exhaust device 104 promotes the air in the upper chamber to circulate to the outside of the sealed house 1, thereby promoting the air in the upper chamber of the sealed house 1 to circulate outward, so that the circulating air cleans the residual gas attached to the parts on the electric telescopic frame 2, thereby preventing the residual hydrogen sulfide gas from affecting the detection accuracy of the next detection.

[0049] Further, see Figure 6-Figure 8 A plurality of ventilation nozzles 72 are arranged on the outside of the collection plug 6 and are distributed at intervals in the circumferential direction. The number of the ventilation nozzles 72 and the through holes on the adjacent collection tube 4 are the same and the positions correspond one to one. The ventilation nozzles 72 are connected to the adjacent ventilation piece 13 through a second hose.

[0050] In the above scheme, the ventilation nozzle 72 corresponds to the adjacent through holes on the adjacent collecting tube 4 one by one, so that the ventilation nozzle 72 can clean the adjacent through holes on the adjacent collecting tube 4. After each time the components on the electric telescopic frame 2 are reset upward, the control terminal pushes the residual gas inside the vacuum chamber into the collecting plug 6 through the ventilation piece 13. The ventilation piece 13 supplies air to the ventilation nozzle 72 through the second hose. The ventilation nozzle 72 cleans the through holes on the collecting tube 4 in a fine manner, further reducing the amount of residual gas on the collecting tube 4, and ensuring that each time the collecting tube 4 is used to take samples, only the content of hydrogen sulfide in the air at the time of this sampling is obtained.

[0051] The above is only an example of the present invention and is not intended to limit the present invention. Any equivalent substitutions made within the principles of the present invention should be included in the protection scope of the present invention. The contents not elaborated in detail in the present invention belong to the existing technologies known to those skilled in the art.
