Therefore, it is necessary to propose a portable electrochemical detection and analysis device that can quickly and conveniently clean the detection device on site. Summary of the invention

[0004] In order to solve the above-mentioned problem that the detection device cannot be cleaned quickly and conveniently on site, an object of the present invention is to provide a portable electrochemical detection and analysis device, which improves the detection efficiency and the accuracy of the detection results by quickly and conveniently cleaning the detection device.

[0005] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a portable electrochemical detection and analysis device, comprising a detection device and a detection system, the detection device and the detection system are connected by signal, the detection device comprises a detection body, a guide assembly for guiding the vertical and rotational movement of the detection body is provided on the top of the detection body, a bag sleeve is detachably connected to the detection body, a drainage sheet is fixedly connected to the bottom of the bag sleeve, the bag sleeve is hollow and provided with a disinfection chamber, a valve block is fixedly connected to the bottom of the disinfection chamber, a pressure sensor is fixedly connected to the inner side wall of the bag sleeve and the bottom of the disinfection chamber, and an opening and closing assembly for controlling the opening and closing of the bag sleeve based on the movement of the guide assembly is provided on the bag sleeve;

[0006] The detection system includes a timing module, an acquisition module, an analysis module, a control module, a collection module and a display module;

[0007] Timing module, used to set the collection time to ensure sufficient contact time;

[0008] The acquisition module is used to obtain the detection component data, the pressure data of the pressure sensor at the bottom of the disinfection chamber, and the pressure data of the pressure sensor inside the pressing bag sleeve; and to acquire the speed at which the guide component drives the detection body to rotate and move vertically, and control the vertical movement distance of the detection body;

[0009] An analysis module is used to analyze the detection component data, analyze the pressure data of the pressure sensor at the bottom of the disinfection chamber, and analyze the pressure data of the pressure sensor inside the pressing bag sleeve;

[0010] A control module is used to monitor the remaining volume of the disinfection chamber in real time according to the analysis of pressure information, and to adjust the output volume of the disinfection chamber by controlling the guide component;

[0011] Collection module, used for statistical collation of detection component data;

[0012] The display module is used to intuitively display the detection component data.

[0013] The principle of the basic scheme is: when pressure is applied to the capsule, the pressure inside the disinfection chamber increases, the valve block at the bottom of the disinfection chamber opens, the clean substances inside the disinfection chamber flow out, and flow to the detection body through the drainage plate. The timing module can set different measurement times according to different measured liquids, the pressure sensor collects the pressure signal, the analysis module analyzes the pressure data of the pressure sensor at the bottom of the disinfection chamber and the pressure data of the pressure sensor inside the capsule, the control module monitors the remaining amount of the disinfection chamber in real time, adjusts the pressing force of the device and adjusts the placement of the device, the collection module statistically stores the collected data, and the display module intuitively displays the detection component data and displays the remaining amount of the disinfection chamber in real time. After the squeezing stops, the valve block closes and the clean substances stop flowing out.

[0014] The beneficial effects of the basic solution are: it simplifies the cleaning process, drainage by drainage sheet can also make the cleaning range more accurate, improve the cleaning speed and efficiency, and make the test results faster and more accurate. Contact with the tested solution strictly according to the set measurement time to ensure sufficient contact time and reduce the problem of inaccurate test results due to poor contact. The pressure on the pressure sensor in the disinfection chamber can be quickly and accurately detected after analysis by the analysis module, and rapid replenishment can be achieved. The pressure on the pressure sensor inside the bag sleeve can not only analyze whether the pressure on the device is appropriate, reduce the problem of damaging the device due to excessive force, but also analyze whether the position of the device is appropriate, ensure that the device is properly placed and protected, and the detection system accurately collects, analyzes and statistically organizes the detection data, which can ensure the integrity and security of the data to the greatest extent.

[0015] At the same time, the guide component can be used to realize the vertical movement of the detection body, so that when performing detection, the length of the detection body extended into the detection sample can be controlled accordingly, thereby achieving the accuracy of the detection result and avoiding the error caused by manual operation. At the same time, the detection body can also be rotated under the action of the guide component. When the detection body rotates, when the disinfectant or gas in the disinfection chamber is output under the action of the guide component, the detection body can be disinfected and cleaned at all angles to prepare for the corresponding detection later, thereby increasing the convenience and flexibility of the use of the device.

[0016] Furthermore, the inner side wall of the bag sleeve is fixedly connected with a first interlayer and a second interlayer, and the first interlayer and the second interlayer separate the disinfection chamber into a disinfection liquid cavity, an air cavity and a water cavity which are arranged transversely in sequence.

[0017] The beneficial effects of the basic solution are: the first interlayer and the second interlayer separate the disinfection chamber, and different types of cleaning substances can be stored at the same time. When a certain cleaning substance is needed, pressure is applied to the corresponding cavity wall, and the corresponding valve block will be opened to release the required cleaning substance, which can make cleaning simpler and more efficient. The gas in the air cavity can also blow away residual moisture, reducing corrosion to the detection head and the impact on the results.

[0018] Further, the guide assembly includes a hollow fixed block, a motor is fixedly connected in the hollow part of the fixed block, the output shaft of the motor is coaxially fixedly connected to the main gear, the main gear is meshed with the slave gear, a sleeve is coaxially fixedly connected to the bottom of the slave gear, the sleeve is rotatably connected to the hollow wall of the fixed block, the sleeve and the inner wall of the slave gear are both fixedly connected with internal threads, the slave gear is coaxially rotatably connected to an extension rod, the outer wall of the extension rod is provided with external threads, the extension rod is threadedly matched with the sleeve and the slave gear through external and internal threads, the extension rod passes through the sleeve and the bottom wall of the fixed block in turn and is fixedly connected to the top of the detection body, and a plurality of telescopic rods are symmetrically fixedly connected to the top of the detection body, and the other ends of the telescopic rods are all fixedly connected to the outer bottom wall of the fixed block;

[0019] An electric telescopic rod is fixedly connected to the bottom wall of the hollow part of the fixed block, the output shaft of the electric telescopic rod is coaxially fixedly connected to the limit block, a vertical limit groove corresponding to the limit block is provided on the extension rod, and the limit block can extend into the vertical limit groove and vertically slide with the vertical limit groove;

[0020] The top of the bag cover is fixedly connected with a plurality of elastic rods, the other ends of the elastic rods are fixedly connected with the bottom of the fixed block, and the inner wall of the bag cover is slidably matched with the detection body.

[0021] The beneficial effects of the basic scheme are: the extension rod can be rotated by starting the motor and the meshing of the main gear and the slave gear, and the detection body can be driven to rotate accordingly, thereby achieving sufficient cleaning. At the same time, when the electric telescopic rod is started, the limit block can be inserted into the limit groove, and then when the motor is started again and the main gear and the slave gear are meshed again, the extension rod will move vertically due to the corresponding limit effect, and the downward movement distance of the extension rod is controlled by the number of rotations, so that the vertical movement distance of the detection body fixedly connected to the extension rod can be controlled, so that the detection depth of the detection body inserted into the sample can be controlled accordingly, thereby achieving a more accurate detection effect;

[0022] Therefore, the design of the guide component can realize flexible detection of the detection body and a relatively complete detection process without blind spots, which makes it more suitable for use of the detection body in more complex environments such as outdoors.

[0023] Furthermore, perspective windows are provided on the sides of the disinfectant liquid cavity, the air cavity and the water cavity, and corresponding replenishment ports are provided on the upper sides of the disinfectant liquid cavity, the air cavity and the water cavity, respectively, and the replenishment ports are all detachably connected with covers.

[0024] The beneficial effects of the basic solution are: the perspective window can visually observe the remaining amount of cleaning material in the cavity, which is convenient for replenishing at any time when the remaining amount is insufficient; the lid can ensure that the cleaning material is sealed and clean, reducing the problem of pollution caused by overflow of the cleaning material.

[0025] Furthermore, the detection device includes a box body, a sponge block is fixedly connected to the inside of the box body, and a placement groove is opened on the sponge block; a screen display and a reset button are respectively fixedly connected to the sponge block, the screen display and the display module signal are connected, and a battery module and a USB interface are respectively fixedly connected to the sponge block.

[0026] The beneficial effects of the basic solution are: the sponge block can reduce shock, the shape of the placement groove corresponds to the detection device, and it is close to the detection device, reducing the problem of damage to the detection device caused by impacts such as bumps;

[0027] After the test results are transmitted from the detection module to the display module, they will be displayed in real time on the display module. In special circumstances, such as when the test results are invalid and need to be cleared, you can press the reset button to send a reset command to the detection module to perform the reset operation, reducing the need for complex operations to invalidate data and improving detection efficiency.

[0028] Furthermore, an indicator light window is provided on the detection body, a detection head is fixedly connected to the bottom of the detection body, and the detection head is connected to the acquisition module signal.

[0029] The beneficial effects of the basic scheme are: the detection work starts when the detection head contacts the detection liquid. When the detection module starts working, the corresponding indicator light window can show the flashing status of the detection module working light, thereby monitoring the working status of the detection module and reducing the impact of poor contact between the detection head and the detection solution on the detection results.

[0030] Furthermore, the detection body includes a body and a detection head which are fixedly connected to each other from top to bottom, the bag cover is wrapped around the outside of the body, and a plurality of guide grooves are opened on the outer wall of the detection head, and a plurality of anti-slip grooves are arranged in the guide grooves.

[0031] The beneficial effect of the basic solution is: through the design of the guide groove, the disinfectant and other cleaning liquids flowing to the outer wall of the detection head can be guided to the position of the detection head port for more precise cleaning, reducing the inability of some cleaning liquids to flow to the corresponding position for corresponding cleaning due to the small diameter of the detection head. At the same time, the anti-slip pattern design can delay the flow time of the cleaning liquid, thereby achieving more thorough cleaning.

[0032] Furthermore, the opening and closing assembly includes a plurality of extrusion blocks fixedly connected to the outer wall of the body, the extrusion blocks are arc-shaped blocks, the inner wall of the bag sleeve is provided with a plurality of card slots corresponding to the extrusion blocks, and the card slots correspond to the positions of the disinfectant liquid chamber, the air chamber and the water chamber respectively, and the lengths of the card slots corresponding to the disinfectant liquid chamber, the air chamber and the water chamber decrease in sequence, and the length of the extrusion block in the corresponding card slot is the same as the length of the card slot;

[0033] A support ring is provided around the outer wall of the bag sleeve, the support ring is fixedly connected to the outer bottom wall of the fixed block, and a vertical groove is provided on the side of the support ring close to the bag sleeve, and a sliding block corresponding to the vertical groove is provided on the outer wall of the bag sleeve. The support ring and the bag sleeve are vertically slidably matched through the vertical groove and the sliding block.

[0034] The beneficial effects of the basic scheme are as follows: in the initial state, the extrusion blocks are respectively located in the card slots. When cleaning is required, the detection body rotates accordingly under the action of the guide assembly. Therefore, because the body and the bag sleeve are slidably matched, the extrusion blocks will move with the rotation of the body and produce relative displacement with the card slots. Therefore, the extrusion blocks will be separated from the card slots and squeeze the bag sleeve, thereby squeezing out the disinfectant in the bag sleeve, thereby achieving the effect of disinfection and cleaning;

[0035] At the same time, because the lengths of the card slots corresponding to the disinfectant chamber, air chamber and water chamber increase successively, the squeezing card block will squeeze the three chambers in sequence, thereby first cleaning, then blowing to help drying and finally spraying disinfectant for disinfection, so as to prepare for subsequent reuse.

[0036] Furthermore, a box cover is loosely connected to the top hinge of the side of the box body.

[0037] The beneficial effect of the basic solution is that when in use, the detection operation can be carried out by opening the box cover. After use, the box cover can form a closed space with the box body, which can better protect the detection device and is convenient to carry, reducing the possibility of device loss.

[0038] Furthermore, handles are fixedly connected to the sides of the box body and the box cover.

[0039] The beneficial effect of the basic solution is that when the device needs to be carried, the handle can be used to enhance the portability and practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Embodiment 1, basically as attached Figure 1-Figure 4 As shown: A portable electrochemical detection and analysis device, including a detection device and a detection system, the detection device and the detection system are connected by signal, the detection device includes a detection body 1, the top of the detection body 1 is provided with a guide assembly for guiding the vertical and rotational movement of the detection body, the detection body 1 is detachably connected with a bag cover 2, the bottom of the bag cover 2 is fixedly connected with a drainage plate 3, the bag cover 2 is hollow and provided with a disinfection chamber 4, the bottom of the disinfection chamber 4 is fixedly connected with a valve block 5, the inner side wall of the bag cover 2 and the bottom of the disinfection chamber 4 are both fixedly connected with a pressure sensor, the inner side wall of the bag cover 2 is fixedly connected with a first interlayer 6 and a second interlayer 7, the first interlayer 6 and the second interlayer 7 divide the disinfection chamber 4 into a disinfection liquid chamber 8, an air chamber 9 and a water chamber 10 which are arranged transversely in sequence. An indicator light window 18 is provided on the detection body 1, and a detection head 19 is fixedly connected to the bottom of the detection body 1, and the detection head 19 is connected to the acquisition module signal;

[0048] The bag cover 2 is provided with an opening and closing component for controlling the opening and closing of the bag cover 2 based on the movement of the guide component.

[0049] The detection system includes a timing module, an acquisition module, an analysis module, a control module, a collection module and a display module;

[0050] Timing module, used to set the collection time to ensure sufficient contact time;

[0051] The acquisition module is used to obtain the detection component data, the pressure data of the pressure sensor at the bottom of the disinfection chamber 4 and the pressure data of the pressure sensor inside the pressing bag sleeve 2; and the speed at which the guide component drives the detection body 1 to rotate and move vertically, and control the vertical movement distance of the detection body 1;

[0052] An analysis module, used to analyze the detection component data, analyze the pressure data of the pressure sensor at the bottom of the disinfection chamber 4, and analyze the pressure data of the pressure sensor inside the pressing bag sleeve 2;

[0053] A control module, used to monitor the remaining amount of the disinfection chamber 4 in real time according to the analysis of the pressure information, and to adjust the output of the disinfection chamber 4 by controlling the guide assembly;

[0054] Collection module, used for statistical collation of detection component data;

[0055] The display module is used to intuitively display the detection component data.

[0056] The specific implementation process is as follows: when cleaning operation is required, pressure is applied to the corresponding part of the bag sleeve 2 where the cleaning material is required. For example, when water cleaning is required, the outer wall of the water cavity 10 is pressed, the pressure inside the water cavity 10 increases, and the valve block 5 at the bottom of the water cavity 10 opens. The water inside the water cavity 10 flows out, is drained by the drainage sheet 3, and flows close to the detection body 1, and finally flows to the detection head 19. After the squeezing stops, the valve block 5 closes and the cleaning material water stops flowing out. The cleaning process is simplified, and the drainage of the drainage sheet 3 can also make the cleaning range more accurate, improve the cleaning speed and efficiency, and cleaning also makes the detection results faster and more accurate. The first interlayer 6 and the second interlayer 7 separate the disinfection chamber 4, and different types of cleaning materials can be stored at the same time. Which cleaning material needs to reduce the pressure on the corresponding cavity wall, and the corresponding valve block 5 will be opened to release the required cleaning material, which can make cleaning simpler and more efficient. The moisture in the water cavity 10 can clean the detection head 19. For some detection solutions, it is not enough to clean them with water only. Incomplete cleaning will affect the next detection result and may also damage the corrosion detection head 19. In this case, the disinfectant in the disinfection cavity can be used for disinfection. The gas in the air cavity 9 can also blow away the residual moisture and reduce the corrosion of the detection head 19.

[0057] The detection work starts when the detection head 19 contacts the detection liquid. The timing module sets the collection time and contacts the tested solution strictly according to the set measurement time to ensure that the contact time is sufficient and reduce the problem of inaccurate detection results due to poor contact. The collection module obtains the detection component data, collects the pressure data of the pressure sensor at the bottom of the disinfection chamber 4 and the pressure data of the pressure sensor inside the pressing bag sleeve 2. The analysis module analyzes the detection component data, analyzes the pressure data of the pressure sensor at the bottom of the disinfection chamber 4 and analyzes the pressure data of the pressure sensor inside the pressing bag sleeve 2. The control module monitors the remaining amount of the disinfection chamber 4 in real time according to the analyzed pressure information to achieve rapid replenishment, adjusts the strength of the pressing device and determines the placement position of the device according to the pressure on the bag sleeve 2 and adjusts the placement position of the device to ensure that the device is properly placed and protected. The collection module statistically organizes the detection component data, and the display module intuitively displays the detection component data, the remaining amount of the disinfection chamber 4 and the pressing strength of the bag sleeve 2 to reduce the problem of damaging the device due to excessive force.

[0058] When the work starts, the corresponding indicator window 18 can show the working light on and off, thereby monitoring the working status and reducing the impact of poor contact between the detection head 19 and the detection solution on the detection result. If it is determined that the detection solution is in good contact with the detection head 19, but the indicator window 18 does not respond, other factors should be considered or the detection module is damaged, saving maintenance time.

[0059] Example 2

[0060] The difference from the above embodiment is that the detection device includes a box 26, a sponge block 16 is fixedly connected inside the box 26, a placement slot 17 is provided on the sponge block 16, a screen display and a reset button 21 are respectively fixedly connected to the sponge block 16, and the screen display and the display module are connected by signal. The top hinge of the side of the box 26 is connected to a box cover 24, and the sides of the box 26 and the box cover 24 are fixedly connected to handles 25, which are convenient to carry and enhance the portability of the device.

[0061] The specific implementation process is as follows: the sponge block 16 can reduce shock, and the shape of the placement groove 17 corresponds to the detection device, so that the detection device is closely protected and the problem of damage to the detection device caused by impacts such as bumps is reduced. When it is needed, the box cover 24 can be opened to perform the detection operation. After use, the box cover 24 can form an enclosed space with the box body 26, which can better protect the detection device and is convenient to carry, reducing the possibility of losing the device.

[0063] The difference from the above embodiment is that, Figure 5 As shown, the guide assembly includes a hollow fixed block 27, a motor 28 is fixedly connected in the hollow part of the fixed block 27, the output shaft of the motor 28 is coaxially fixedly connected to a main gear 31, the main gear 31 is meshed with a slave gear 30, a sleeve 40 is coaxially fixedly connected to the bottom of the slave gear 30, the sleeve 40 is rotatably connected to the hollow wall of the fixed block 27, the sleeve 40 and the inner wall of the slave gear 30 are both fixedly connected with internal threads, the slave gear 30 is coaxially rotatably connected to an extension rod 29, the outer wall of the extension rod 29 is provided with an external thread, the extension rod 29 is threadedly matched with the sleeve 40 and the slave gear 30 through external and internal threads, the extension rod 29 passes through the sleeve 40 and the bottom wall of the fixed block 27 in turn and is fixedly connected to the top of the detection body 1, and a plurality of telescopic rods 36 are symmetrically fixedly connected to the top of the detection body 1, and the other ends of the telescopic rods 36 are fixedly connected to the outer bottom wall of the fixed block 27;

[0064] An electric telescopic rod 32 is fixedly connected to the bottom wall of the hollow part of the fixed block 27, and the output shaft of the electric telescopic rod 32 is coaxially fixedly connected to the limit block 33. A vertical limit groove 37 corresponding to the limit block 33 is provided on the extension rod 29, and the limit block 33 can extend into the vertical limit groove 37 and vertically slide with the vertical limit groove 37;

[0065] A plurality of elastic rods 35 are fixedly connected to the top of the bag cover 2 , and the other ends of the elastic rods 35 are fixedly connected to the bottom of the fixing block 27 . The inner wall of the bag cover 2 is slidably matched with the detection body 1 .

[0066] The specific implementation process is as follows: when performing the detection, the motor 28 is first started. Under the drive of the motor 28, the main gear 31 rotates, and then because the slave gear 30 is meshed with the main gear 31, the slave gear 30 can perform a corresponding rotational movement. Then, because the slave gear 30 and the extension rod 29 are threadedly matched, the extension rod 29 can rotate under the drive of the slave gear 30. However, because the limit block 33 is located in the vertical limit groove 37 and limits the rotational movement of the extension rod 29, the rotational movement of the extension rod 29 can be converted into a vertical downward movement. At the same time, because the extension rod 29 is fixedly connected to the detection body 1, the detection body 1 can be controlled to move vertically in the number of rotations of the motor 28. The corresponding length, thereby limiting the height of the detection body 1 extending into the detection sample, thereby achieving more accurate detection, reducing errors caused by subjective operations, and more convenient for flexible operation in actual environments;

[0067] At the same time, when the detection is completed, the motor 28 can be started to move the detection body 1 upward and then return to its original position. When performing the next detection, the detection body 1 needs to be cleaned and disinfected accordingly to reduce the impact of residual liquid of different samples on subsequent detection.

[0069] The difference from the above embodiment is that a perspective window 13 is provided on the side of the disinfectant liquid chamber 8, the air chamber 9 and the water chamber 10, and a plurality of replenishing ports 14 are respectively provided on the top of the disinfectant liquid chamber 8, the air chamber 9 and the water chamber 10, and the replenishing ports 14 are all detachably connected with a cover 15.

[0070] The specific implementation process is as follows: the perspective window 13 can intuitively observe the remaining cleaning material in the cavity, which is convenient for replenishment at any time. For example, when it is observed that the remaining amount of the water cavity 10 is not much, it can be replenished through the replenishment port 14 above the water cavity 10. The cover 15 can ensure that the cleaning material is sealed and clean, reducing the problem of pollution caused by overflow of the cleaning material.

[0073] The specific implementation process is as follows: After the detection result is transmitted from the detection module to the screen display module 20, it will be displayed in real time on the screen display module 20. In special circumstances, such as when the detection result is invalid and the detection result needs to be cleared, the reset button 21 can be pressed to send a reset instruction to the detection module to perform a reset operation, thereby reducing the need for complex operations to invalidate data and improving detection efficiency. The battery module 22 and the USB interface 23 can be powered by replacing the battery or connecting a charging device when there is no electricity, thereby enhancing the adaptability of the detection device to various situations. The USB interface 23 can also be connected to a printer to print out the detection results.

[0074] Example 6

[0075] The difference from the above embodiment is that the detection body 1 includes a body and a detection head 19 fixedly connected to each other from top to bottom, the bag cover 2 is wrapped around the outside of the body, and the outer wall of the detection head 19 is provided with a plurality of guide grooves 42, and a plurality of anti-slip grooves are provided in the guide grooves 42.

[0076] The specific implementation process is as follows: through the design of the guide groove 42, the flowing disinfectant can be more accurately guided to the position of the detection head 19, so as to achieve sufficient cleaning and disinfection of the detection head 19, avoiding the problem of insufficient cleaning due to the small diameter of the detection head 19.

[0077] Example 7

[0078] The difference from the above embodiment is that the opening and closing assembly includes a plurality of extrusion blocks 38 fixedly connected to the outer wall of the body, the extrusion blocks 38 are arc-shaped blocks, and the inner wall of the bag sleeve 2 is provided with a plurality of card slots 39 corresponding to the extrusion blocks 38, and the card slots 39 correspond to the positions of the disinfectant liquid chamber 8, the air chamber 9 and the water chamber 10 respectively, and the lengths of the card slots 39 corresponding to the disinfectant liquid chamber 8, the air chamber 9 and the water chamber 10 are increased in sequence, and the length of the extrusion blocks 38 in the corresponding card slots 39 is the same as the length of the card slots 39;

The support ring 41 and the bag sleeve 2 are vertically slidably matched through the vertical groove 34 and the sliding block.

[0080] The specific implementation process is as follows: when cleaning the detection body 1, first start the motor 28, and then start the electric telescopic rod 32, so that the limit block 33 is disengaged from the vertical limit groove 37, thereby under the rotation of the main gear 31 and the slave gear 30, the extension rod 29 will perform a corresponding rotation movement because it is disengaged from the limit, and then the body rotates, and at the same time, the extrusion block 38 on the outer wall of the body will gradually disengage from the slot 39 according to the length of the slot 39, wherein the lengths of the slots 39 corresponding to the disinfectant chamber 8, the air chamber 9 and the water chamber 10 increase successively, so when the body rotates, the extrusion block 38 corresponding to the water chamber 10 will first be disengaged from the slot 39, so the extrusion block 38 will first squeeze the water chamber 10, and under the action of squeezing, water will flow out of the water chamber 10 and flow into the guide groove 42. Under the action of, the water is guided to the position of the detection head 19, and because the body is rotating at this time, the water will flow circumferentially to the detection head 19, so as to achieve sufficient cleaning. After rotating to a certain angle, the air cavity 9 will be started under the corresponding rotation, and then blown toward the detection head 19. Under the action of the air flow, on the one hand, some of the foreign particles remaining on the detection head 19 can be blown away, and on the other hand, the flow of water can be accelerated to increase the flow range of the water, thereby achieving comprehensive cleaning. Finally, the disinfectant chamber 8 can also be squeezed to and output the corresponding disinfectant, so as to achieve disinfection of the detection head 19. Therefore, the cleaning and disinfection operations of the detection head 19 can be achieved only by rotating the detection body 1, which is suitable for convenient cleaning and detection in complex situations such as outdoors.
