[0002] When traffic police perform drunk driving inspection tasks, alcohol detectors often need to be used by a large number of people, which is easy to cause cross infection. Therefore, we provide an alcohol detector, including a blowing device, an alcohol detector, a cleaning device, and a disinfection device. The alcohol detector is set on the detection body, the cleaning device is set on the detection body and is used to clean the blowing device, and the disinfection device is set on the detection body and is used to disinfect the blowing device. Summary of the invention

[0003] The invention aims to solve the technical problem of how to integrate a paintball gun with an alcohol detector and disinfect and clean the alcohol detector, and provides an alcohol detector.

[0004] The technical solution adopted by the present invention to solve its technical problem is: The alcohol detector comprises an air blowing device, a detection body, a detection cavity, an alcohol detector, a cleaning device, a disinfecting device, and a paintball launcher. The detection cavity is arranged inside the detection body. The air blowing device is arranged on the detection body and is connected with the detection cavity. The alcohol detector is arranged on the detection body, and the induction head of the alcohol detector is in the detection cavity. The cleaning device is arranged on the detection body and is used to clean the air blowing device. The disinfecting device is arranged on the detection body and is used to disinfect the air blowing device. The paintball launcher is arranged on the side of the detection body and is connected to the detection body by screws.

[0005] When testing for drunk driving, the user asks the person being tested to blow air from the blowing device into the testing cavity, and then the alcohol detector detects the airflow. The blowing device is then disinfected and cleaned by the cleaning device and the disinfection device. The paintball launcher can be flexibly disassembled.

[0006] Furthermore, the blowing device includes two blowing cylinders, two blowing channels, two one-way valve sheets, a first piston, a first spring, and a piston channel. The piston channel is vertically arranged in the detection body, directly below the detection cavity, the lower end of the piston channel is connected to the bottom surface of the detection body, and the upper end is connected to the detection cavity. The first piston is slidably arranged in the piston channel. The first spring is arranged in the piston channel, below the first piston, the upper end is fixedly connected to the first piston, and the lower end is fixedly connected to the detection body. The two blowing channels are vertically arranged at the top of the detection body, above the detection cavity, the upper end of the blowing channel is connected to the outside, and the lower end is connected to the detection cavity. The two blowing cylinders respectively vertically pass through the two blowing channels and extend into the detection cavity, and the blowing cylinders are slidably connected to the blowing channels. Two one-way valve plates are arranged horizontally in the detection cavity, respectively below the two air cylinders. The one-way valve plates close the lower ports of the corresponding air cylinders. A rubber layer is arranged on the upper surface of the one-way valve plates. The side of the one-way valve plates is rotatably connected to the lower ends of the corresponding air cylinders through a rotating shaft, and the rotating axis is arranged horizontally. A torsion spring is sleeved on the rotating shaft of the one-way valve plates, one end of the torsion spring is fixedly connected to the corresponding one-way valve plates, and the other end is fixedly connected to the corresponding air cylinders.

[0007] When testing for drunk driving, the user asks the person being tested to blow air from a blowpipe, and the airflow enters the blowpipe, and then pushes the corresponding one-way valve plate to rotate. The corresponding one-way valve plate rotates and drives the corresponding linkage rod to rotate outside the linkage groove, and then the airflow enters the detection cavity, increasing the air pressure in the detection cavity, thereby pushing the first piston to move downward and compressing the first spring. When the person being tested finishes blowing, the opened one-way valve plate rotates under the action of the torsion spring, and the corresponding blowpipe is closed again, so that the airflow in the detection cavity is retained. At this time, the alcohol detector can detect the gas in the detection cavity more stably and for a long time, thereby improving the accuracy of alcohol detection.

[0008] Furthermore, the cleaning device includes a water storage chamber, a water inlet pipe, a piston groove, a second piston, a piston rod, a first channel, a plurality of second channels, a plurality of nozzles, two water retaining rings, a one-way control device, two connecting plates, and two linkage rods. The piston groove is vertically arranged on the inner top surface of the detection cavity and is directly above the piston channel. The second piston is slidably arranged in the piston groove. The piston rod is vertically arranged between the first piston and the second piston, the lower end of the piston rod is fixedly connected to the first piston, and the upper end is fixedly connected to the second piston. Two connecting plates are vertically arranged in the detection cavity and correspond to the two one-way valve plates respectively. The connecting plates are parallel to the axis of the rotating shaft of the corresponding one-way valve plate and are arranged close to the rotating shaft of the corresponding one-way valve plate. The connecting plates are fixedly connected to the piston rod through a support rod. A linkage groove is arranged on the side of the connecting plate close to the corresponding one-way valve plate. The linkage groove is a circular arc groove, and its center coincides with the axis of the rotating shaft of the corresponding one-way valve plate. Two linkage rods are arranged horizontally, and correspond to two one-way valve plates and two connecting plates respectively. The linkage rod is perpendicular to the axis of the rotating shaft of the corresponding one-way valve plate. The linkage rod is arranged between the corresponding one-way valve plate and the corresponding connecting plate. One end of the linkage rod is fixedly connected to the corresponding one-way valve plate, and the other end extends into the corresponding linkage groove, and the linkage rod cooperates with the corresponding linkage groove. The water storage chamber is arranged in the detection body. The first channel is arranged in the detection body, one end is connected to the bottom of the water storage chamber, and the other end is connected to the piston groove and is located above the second piston. The first one-way valve is arranged in the first channel. Several second channels are arranged in the detection body, one end is connected to the piston groove and is located above the second piston, and the second one-way valve is arranged in the second channel. Two water retaining rings are respectively sleeved outside the two air cylinders and are located above the detection body. The two water retaining rings are fixedly connected to the top of the detection body. Several nozzles are respectively fixed to the inner surfaces of the two water retaining rings and are respectively arranged around the two air cylinders. Several nozzles are respectively connected to the other ends of several second channels. The water inlet pipe runs through the side of the detection body and is connected to the water storage chamber. A third one-way valve is arranged in the water inlet pipe. The one-way control device is arranged on the side of the detection body and is connected to the piston rod. The linkage rod cooperates with the corresponding linkage groove, so that the linkage rod can be separated from the linkage groove when it rotates, and cannot be separated from the linkage groove when it does not rotate.

[0009] The first piston drives the piston rod and the pressing rod to move downward, the piston rod drives the two connecting plates, the second piston and the fixed teeth to move downward, and the second piston drives the water in the water storage chamber to enter the piston groove through the first channel and the first one-way valve in sequence. The water in the water storage chamber is replenished through the water inlet pipe.

[0010] Furthermore, the cleaning device includes two first sealing rings, a pressing rod, and two limiting rings. The two first sealing rings are respectively sleeved on the bottom of the two blowing cylinders and fixed to the inner top surface of the detection cavity. The pressing rod is vertically arranged below the first piston, and the lower end extends through the piston channel to the bottom of the detection body. The two limiting rings are respectively sleeved on the bottom of the two blowing cylinders, located in the detection cavity, and the two limiting rings are connected to the top surface of the detection cavity.

[0011] By providing two first sealing rings, the sliding of the two blowing cylinders can be sealed.

[0012] Furthermore, the one-way control device includes a second spring, a sliding block, a plurality of one-way teeth, a fixed tooth, a connecting ring, and an air relief groove. The sliding block is a prism, which extends horizontally through the side of the detection body into the detection cavity, and the sliding block is connected to the detection body in a sliding and sealing manner. A plurality of one-way teeth are vertically fixed to the side of the sliding block close to the piston rod, and the tooth tips of the one-way teeth are tilted downward. The fixed teeth are fixed to the side of the piston rod, meshed with the one-way teeth, and abutted against the sliding block. The second spring is arranged in the detection cavity, sleeved outside the sliding block, one end is fixedly connected to the detection body, and the other end is fixedly connected to the sliding block, and the second spring is in a compressed state. The connecting ring is arranged outside the detection body and fixedly connected to the sliding block. The air relief groove is arranged on the side of the sliding block, and cooperates with the sliding process of the sliding block, so that the sliding block can be deflated and rotated when it moves outward to expose the air relief groove.

[0013] When the fixed tooth moves downward and passes through a plurality of one-way teeth, it pushes the plurality of one-way teeth, the sliding block and the connecting ring to move outward. After the fixed tooth passes through the one-way teeth, the plurality of one-way teeth, the sliding block and the connecting ring are reset under the action of the second spring, so that the fixed tooth and the piston rod can only move downward in one direction.

[0014] After testing a person, the user turns the test body upside down, and then pulls the connecting ring, the sliding block, the air relief groove, and several one-way teeth outward until the air relief groove is exposed, so that the several one-way teeth are separated from the fixed teeth. Then, the first piston approaches the piston groove under the action of the first spring, and the gas in the test cavity flows out from the air relief groove. The first piston drives the piston rod, two connecting plates, the second piston, and the fixed teeth to move toward the piston groove, and the connecting plate drives the linkage rod, the one-way valve plate, and the air blow tube to move and reset through the linkage groove. Due to the presence of the torsion spring, the connecting plate can drive the linkage rod, the one-way valve plate, and the air blow tube to move and reset through the linkage groove.

[0015] Furthermore, the air relief groove is a circular groove, and the length of the air relief groove is greater than the thickness of the inner wall of the detection cavity.

[0016] If drunk driving is detected, the alcohol gas in the detection cavity needs to be removed before testing the next person to avoid affecting the test results. At this time, the user first pulls the connecting ring, the sliding block, the air relief groove, and several one-way teeth outward until the air relief groove is exposed, so that the several one-way teeth are separated from the fixed teeth, and then rotates the connecting ring 180 degrees. The connecting ring drives the sliding block, the air relief groove, and several one-way teeth to rotate 180 degrees, and then releases the connecting ring to reset the sliding block, the air relief groove, and several one-way teeth, so that the fixed teeth can only move upward in one direction. Since the air relief groove is a circular groove, the sliding block part where it is located is cylindrical, which can make the sliding block rotate.

[0017] Then the user pushes the pressing rod upward, and the pressing rod drives the first piston, the piston rod, the two connecting plates, the second piston, and the fixed teeth to move upward until the first piston is separated from the piston channel and enters the detection cavity. Due to the presence of two limit rings, the two air cylinders move upward, and the two connecting plates drive the two linkage rods and the two one-way valve plates to rotate through the two linkage grooves to open the two air cylinders. At this time, a number of one-way teeth can prevent the first piston, the piston rod, and the two one-way valve plates from resetting through the fixed teeth, thereby maintaining the connection between the inside and outside of the detection cavity, so that the alcohol gas in the detection cavity can flow to the outside until the alcohol concentration is not displayed on the display. And every once in a while, the two air cylinders and the inner wall of the detection cavity can be disinfected and cleaned with disinfectant in this state to prevent bacteria from growing.

[0018] Furthermore, the disinfection device includes a disinfection chamber, a rehydration tube, two disinfection troughs, two absorbent cotton rings, two absorbent cotton ropes, and two disinfection channels. The disinfection chamber is arranged in the detection body. The rehydration tube passes through the side of the detection body and is connected to the disinfection chamber, and a fourth one-way valve is arranged in the rehydration tube. The two disinfection channels are arranged inside the detection body, and one end is connected to the disinfection chamber. The two disinfection troughs are annular, respectively arranged on the inner surfaces of the two blowing channels, and respectively connected to the other ends of the two disinfection channels. The two absorbent cotton rings are respectively arranged in the two disinfection troughs, and are respectively sleeved on the outside of the two blowing cylinders. The two absorbent cotton ropes are respectively arranged in the two disinfection channels, one end of which is respectively connected to the two absorbent cotton rings, and the other end extends to the bottom of the disinfection chamber.

[0019] When the two connecting plates move downward, one of the connecting plates drives the other connecting rod, the one-way valve plate, and the air cylinder to move downward through the connecting groove. When the air cylinder descends, it moves relative to the absorbent cotton ring, so that the absorbent cotton ring disinfects the surface of the air cylinder with a comprehensive disinfectant, thereby preventing cross infection. The disinfectant in the disinfection chamber will continuously replenish the disinfectant in the two absorbent cotton rings through the two absorbent cotton ropes.

[0020] The second piston pushes the water in the piston groove to be sprayed out through a plurality of second channels, a plurality of second one-way valves, and a plurality of nozzles in sequence, so as to clean the disinfectant on the surface of the sterilized blowpipe and clean the saliva on the surface of the blowpipe that has just been used.

[0021] The disinfectant in the disinfection chamber is supplemented through the liquid replenishment tube.

[0022] Furthermore, the diameters of the two absorbent cotton ropes match the inner diameters of the two disinfection channels, thereby preventing the disinfectant in the disinfection cavity from flowing out when the user turns the detection body upside down.

[0023] Furthermore, the alcohol detector includes an alcohol detection sensor, a display screen, and a battery. The alcohol detection sensor is arranged on the detection body, and the induction head of the alcohol detection sensor is located in the detection cavity. The display screen is fixed to the side of the detection body and is electrically connected to the alcohol detection sensor. The battery is arranged in the detection body and is electrically connected to the alcohol detection sensor and the display screen.

[0024] When the alcohol detection sensor detects the alcohol concentration, it will be displayed on the display.

[0025] Furthermore, it includes a blowing button, which is arranged in the piston channel and below the first piston. The blowing button is fixedly connected to the detection body and electrically connected to the display screen.

[0026] When the first piston presses the blow button, the display screen shows that the blowing meets the standard, thereby preventing the person being tested from deliberately not blowing in order to evade the test.

[0027] Beneficial effects of the present invention: 1. The air blowing device can be disinfected and cleaned through the cleaning device and the disinfecting device.

[0028] 2. When detecting drunk driving, the user asks the person being tested to blow air from a blow tube. The air flow enters the blow tube and then pushes the corresponding one-way valve plate to rotate. The rotation of the corresponding one-way valve plate drives the corresponding linkage rod to rotate outside the linkage groove. Then the air flow enters the detection cavity, increasing the air pressure in the detection cavity, thereby pushing the first piston to move downward to compress the first spring until the first piston presses the blow button. When the first piston presses the blow button, the display screen shows that the blowing meets the standard, thereby preventing the person being tested from deliberately not blowing air in order to evade the test.

[0029] 3. When the person being tested finishes blowing, the opened one-way valve rotates under the action of the torsion spring, and the corresponding blow tube is closed again, so that the airflow in the detection cavity is retained. At this time, the alcohol detection sensor can detect the gas in the detection cavity more stably and permanently, thereby improving the accuracy of alcohol detection. When the alcohol detection sensor detects the alcohol concentration, it will be displayed on the display.

[0030] 4. If drunk driving is detected, the alcohol gas in the detection cavity needs to be removed before testing the next person to avoid affecting the test results. At this time, the user first pulls the connecting ring, sliding block, air relief groove, and several one-way teeth outward until the air relief groove is exposed, so that the several one-way teeth are separated from the fixed teeth, and then rotates the connecting ring 180 degrees. The connecting ring drives the sliding block, air relief groove, and several one-way teeth to rotate 180 degrees, and then releases the connecting ring to reset the sliding block, air relief groove, and several one-way teeth, so that the fixed teeth can only move upward in one direction. Since the air relief groove is a circular groove, the sliding block part where it is located is cylindrical, which can make the sliding block rotate. Then the user pushes the pressing rod upward, and the pressing rod drives the first piston, the piston rod, the two connecting plates, the second piston, and the fixed teeth to move upward until the first piston is separated from the piston channel and enters the detection cavity. The two connecting plates drive the two linkage rods and the two one-way valves to rotate through the two linkage grooves to open the two air cylinders. At this time, a number of one-way teeth can prevent the first piston, the piston rod, and the two one-way valves from resetting through the fixed teeth, thereby maintaining the connection between the inside and outside of the detection cavity, so that the alcohol gas in the detection cavity can flow to the outside until the alcohol concentration is not displayed on the display. And every once in a while, the two air cylinders and the inner wall of the detection cavity can be disinfected and cleaned with disinfectant in this state to prevent bacteria from growing.

[0031] 5. The present invention realizes the process of automatically and alternately cleaning, disinfecting and cleaning the saliva on the surfaces of the two blowing cylinders with disinfectant, thereby avoiding cross infection. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The concept and technical effects of the present invention will be clearly and completely described below in conjunction with embodiments to fully understand the purpose, features and effects of the present invention.

[0035] like Figure 1-2As shown, the alcohol detector includes an air blowing device, a detection body 1, a detection cavity 14, an alcohol detector, a cleaning device, a disinfecting device, and a paintball launcher 4. The detection cavity 14 is arranged inside the detection body 1. The air blowing device is arranged on the detection body 1 and is connected with the detection cavity 14. The alcohol detector is arranged on the detection body 1, and the sensing head of the alcohol detector is in the detection cavity 14. The cleaning device is arranged on the detection body 1, and is used to clean the air blowing device. The disinfecting device is arranged on the detection body 1, and is used to disinfect the air blowing device. The paintball launcher 4 is arranged on the side of the detection body 1, and is connected to the detection body 1 by screws.

[0036] When detecting drunk driving, the user allows the person being tested to blow air from the blowing device into the detection cavity 14, and then the alcohol detector detects the airflow. The blowing device is then disinfected and cleaned by the cleaning device and the disinfection device. The paintball launcher 4 can be flexibly disassembled.

[0037] The blowing device includes two blowing cylinders 2, two blowing channels, two one-way valve sheets 24, a first piston 33, a first spring 34, and a piston channel 36. The piston channel 36 is vertically arranged in the detection body 1, directly below the detection cavity 14, the lower end of the piston channel 36 is connected to the bottom surface of the detection body 1, and the upper end is connected to the detection cavity 14. The first piston 33 is slidably arranged in the piston channel 36. The first spring 34 is arranged in the piston channel 36, below the first piston 33, the upper end is fixedly connected to the first piston 33, and the lower end is fixedly connected to the detection body 1. The two blowing channels are vertically arranged at the top of the detection body 1, above the detection cavity 14, the upper end of the blowing channel is connected to the outside, and the lower end is connected to the detection cavity 14. The two blowing cylinders 2 respectively vertically pass through the two blowing channels and extend into the detection cavity 14, and the blowing cylinders 2 are slidably connected to the blowing channels. Two one-way valve sheets 24 are horizontally arranged in the detection cavity 14, respectively below the two air cylinders 2. The one-way valve sheets 24 close the lower ports of the corresponding air cylinders 2. A rubber layer is provided on the upper surface of the one-way valve sheets 24. The side of the one-way valve sheets 24 is rotatably connected to the lower end of the corresponding air cylinder 2 through a rotating shaft, and its rotating axis is horizontally arranged. A torsion spring is sleeved on the rotating shaft of the one-way valve sheets 24, one end of the torsion spring is fixedly connected to the corresponding one-way valve sheets 24, and the other end is fixedly connected to the corresponding air cylinder 2.

[0038] When detecting drunk driving, the user lets the person being tested blow air from a blow tube 2, and the airflow enters the blow tube 2, and then pushes the corresponding one-way valve plate 24 to rotate. The corresponding one-way valve plate 24 rotates and drives the corresponding linkage rod to rotate outside the linkage groove, and then the airflow enters the detection cavity 14, so that the air pressure in the detection cavity 14 increases, thereby pushing the first piston 33 to move downward and compress the first spring 34. When the person being tested finishes blowing, the opened one-way valve plate 24 rotates under the action of the torsion spring, and the corresponding blow tube 2 is closed again, so that the airflow in the detection cavity 14 is retained. At this time, the alcohol detector can detect the gas in the detection cavity 14 more stably and permanently, thereby improving the accuracy of alcohol detection.

[0039] The cleaning device includes a water storage chamber 11, a water inlet pipe, a piston groove 31, a second piston 32, a piston rod 3, a first channel, a plurality of second channels, a plurality of nozzles 22, two water retaining rings 21, a one-way control device, two connecting plates 25, and two linkage rods. The piston groove 31 is vertically arranged on the inner top surface of the detection cavity 14 and is directly above the piston channel 36. The second piston 32 is slidably arranged in the piston groove 31. The piston rod 3 is vertically arranged between the first piston 33 and the second piston 32, and the lower end is fixedly connected to the first piston 33, and the upper end is fixedly connected to the second piston 32. Two connecting plates 25 are vertically arranged in the detection cavity 14, and correspond to the two one-way valve discs 24 respectively. The connecting plates 25 are parallel to the rotation axis of the corresponding one-way valve discs 24, and are arranged close to the rotation axis of the corresponding one-way valve discs 24. The connecting plates 25 are fixedly connected to the piston rod 3 through the support rod. A linkage groove is arranged on the side of the connecting plate 25 close to the corresponding one-way valve disc 24. The linkage groove is a circular arc groove, and its center coincides with the rotation axis of the corresponding one-way valve disc 24. Two linkage rods are arranged horizontally, and correspond to the two one-way valve discs 24 and the two connecting plates 25 respectively. The linkage rod is perpendicular to the rotation axis of the corresponding one-way valve disc 24. The linkage rod is arranged between the corresponding one-way valve disc 24 and the corresponding connecting plate 25, one end of which is fixedly connected to the corresponding one-way valve disc 24, and the other end extends into the corresponding linkage groove, and the linkage rod cooperates with the corresponding linkage groove. The water storage cavity 11 is arranged in the detection body 1. The first channel is arranged in the detection body 1, one end of which is connected to the bottom of the water storage chamber 11, and the other end of which is connected to the piston groove 31 and is located above the second piston 32, and a first one-way valve is arranged in the first channel. Several second channels are arranged in the detection body 1, one end of which is connected to the piston groove 31 and is located above the second piston 32, and a second one-way valve is arranged in the second channel. Two water retaining rings 21 are respectively sleeved outside the two air cylinders 2 and are located above the detection body 1, and the two water retaining rings 21 are fixedly connected to the top of the detection body 1. Several nozzles 22 are respectively fixed to the inner surfaces of the two water retaining rings 21 and are respectively arranged around the two air cylinders 2, and several nozzles 22 are respectively connected to the other ends of several second channels. The water inlet pipe runs through the side of the detection body 1 and is connected to the water storage chamber 11, and a third one-way valve is arranged in the water inlet pipe. The one-way control device is arranged on the side of the detection body 1 and is connected to the piston rod 3. The linkage rod cooperates with the corresponding linkage groove, so that the linkage rod can be separated from the linkage groove when it rotates, and cannot be separated from the linkage groove when it does not rotate.

[0040] The first piston 33 drives the piston rod 3 and the pressing rod 37 to move downward, the piston rod 3 drives the two connecting plates 25, the second piston 32 and the fixed teeth 51 to move downward, and the second piston 32 drives the water in the water storage chamber 11 to sequentially pass through the first channel and the first one-way valve into the piston groove 31. The water in the water storage chamber 11 is replenished through the water inlet pipe.

[0041] The cleaning device includes two first sealing rings, a pressing rod 37, and two limiting rings. The two first sealing rings are respectively sleeved on the bottom of the two blowing cylinders 2 and fixed to the inner top surface of the detection cavity 14. The pressing rod 37 is vertically arranged below the first piston 33, and the lower end extends to the bottom of the detection body 1 through the piston channel 36. The two limiting rings are respectively sleeved on the bottom of the two blowing cylinders 2, located in the detection cavity 14, and the two limiting rings are connected to the top surface of the detection cavity 14.

[0042] By providing two first sealing rings, the sliding of the two blowing cylinders 2 can be sealed.

[0043] The one-way control device includes a second spring 53, a sliding block 5, a plurality of one-way teeth 52, a fixed tooth 51, a connecting ring 54, and an air release groove 55. The sliding block 5 is a prism, which extends horizontally through the side of the detection body 1 to the detection cavity 14, and the sliding block 5 is connected to the detection body 1 in a sliding and sealing manner. A plurality of one-way teeth 52 are vertically fixed to the side of the sliding block 5 close to the piston rod 3, and the tooth tips of the one-way teeth 52 are inclined downward. The fixed tooth 51 is fixed to the side of the piston rod 3, meshed with the one-way teeth 52, and abutted against the sliding block 5. The second spring 53 is arranged in the detection cavity 14, sleeved outside the sliding block 5, one end is fixedly connected to the detection body 1, and the other end is fixedly connected to the sliding block 5, and the second spring 53 is in a compressed state. The connecting ring 54 is arranged outside the detection body 1, and is fixedly connected to the sliding block 5. The air release groove 55 is arranged on the side of the sliding block 5 and cooperates with the sliding process of the sliding block 5, so that the sliding block 5 can release air and rotate when it moves outwards until the air release groove 55 is exposed.

[0044] When the fixed tooth 51 moves downward and passes through the one-way teeth 52, it pushes the one-way teeth 52, the sliding block 5, and the connecting ring 54 to move outward. After the fixed tooth 51 passes through the one-way teeth 52, the one-way teeth 52, the sliding block 5, and the connecting ring 54 are reset under the action of the second spring 53, so that the fixed tooth 51 and the piston rod 3 can only move downward in one direction.

[0045] After testing a person, the user turns the test body 1 upside down, and then pulls the connecting ring 54, the sliding block 5, the air relief groove 55, and the one-way teeth 52 outward until the air relief groove 55 is exposed, so that the one-way teeth 52 are separated from the fixed teeth 51. Then, the first piston 33 approaches the piston groove 31 under the action of the first spring 34, and the gas in the test cavity 14 flows out from the air relief groove 55. The first piston 33 drives the piston rod 3, the two connecting plates 25, the second piston 32, and the fixed teeth 51 to move toward the piston groove 31, and the connecting plate 25 drives the linkage rod, the one-way valve plate 24, and the air tube 2 to move and reset through the linkage groove. Due to the presence of the torsion spring, the connecting plate 25 can drive the linkage rod, the one-way valve plate 24, and the air tube 2 to move and reset through the linkage groove.

[0046] The air relief groove 55 is a circular groove, and the length of the air relief groove 55 is greater than the thickness of the inner wall of the detection cavity 14 .

[0047] If drunk driving is detected, the alcohol gas in the detection cavity 14 needs to be removed before testing the next person to avoid affecting the test results. At this time, the user first pulls the connecting ring 54, the sliding block 5, the air release groove 55, and the one-way teeth 52 outward until the air release groove 55 is exposed, so that the one-way teeth 52 are separated from the fixed teeth 51, and then rotates the connecting ring 54 180 degrees, and the connecting ring 54 drives the sliding block 5, the air release groove 55, and the one-way teeth 52 to rotate 180 degrees, and then releases the connecting ring 54, so that the sliding block 5, the air release groove 55, and the one-way teeth 52 are reset, so that the fixed teeth 51 can only move upward in one direction. Since the air release groove 55 is a circular ring groove, the part of the sliding block 5 where it is located is cylindrical, which can make the sliding block 5 rotate.

[0048] Then the user pushes the pressing rod 37 upward, and the pressing rod 37 drives the first piston 33, the piston rod 3, the two connecting plates 25, the second piston 32, and the fixed teeth 51 to move upward until the first piston 33 is separated from the piston channel 36 and enters the detection cavity 14. Due to the presence of two limit rings, the two blowing cylinders 2 move upward, and the two connecting plates 25 drive the two linkage rods and the two one-way valve plates 24 to rotate through the two linkage grooves to open the two blowing cylinders 2. At this time, a number of one-way teeth 52 can prevent the first piston 33, the piston rod 3, and the two one-way valve plates 24 from resetting through the fixed teeth 51, thereby maintaining the connection between the inside and outside of the detection cavity 14, so that the alcohol gas in the detection cavity 14 can flow to the outside until the alcohol concentration is not displayed on the display screen 15. And every once in a while, the two blowing cylinders 2 and the inner wall of the detection cavity 14 can be disinfected and cleaned with disinfectant in this state to prevent bacteria from growing.

[0049] The disinfection device includes a disinfection chamber 12, a rehydration tube, two disinfection troughs, two absorbent cotton rings 23, two absorbent cotton ropes 13, and two disinfection channels. The disinfection chamber 12 is arranged in the detection body 1. The rehydration tube passes through the side of the detection body 1 and is connected to the disinfection chamber 12, and a fourth one-way valve is arranged in the rehydration tube. The two disinfection channels are arranged inside the detection body 1, and one end is connected to the disinfection chamber 12. The two disinfection troughs are annular, respectively arranged on the inner surfaces of the two blowing channels, and respectively connected to the other ends of the two disinfection channels. The two absorbent cotton rings 23 are respectively arranged in the two disinfection troughs, and are respectively sleeved on the outside of the two blowing tubes 2. The two absorbent cotton ropes 13 are respectively arranged in the two disinfection channels, one end is respectively connected to the two absorbent cotton rings 23, and the other end extends to the bottom of the disinfection chamber 12.

[0050] When the two connecting plates 25 move downward, one of the connecting plates 25 drives the other connecting rod, the one-way valve plate 24 and the air blowing tube 2 to move downward through the connecting groove. When the air blowing tube 2 descends, it moves relative to the absorbent cotton ring 23, so that the absorbent cotton ring 23 fully disinfects the surface of the air blowing tube 2 with disinfectant, thereby preventing cross infection. The disinfectant in the disinfection chamber 12 will continuously replenish the disinfectant in the two absorbent cotton rings 23 through the two absorbent cotton ropes 13.

[0051] The second piston 32 pushes the water in the piston groove 31 to be sprayed out through the plurality of second channels, the plurality of second one-way valves, and the plurality of nozzles 22 in sequence, so as to clean the disinfectant on the surface of the sterilized blow tube 2 and clean the saliva on the surface of the blow tube 2 that has just been used.

[0052] The disinfectant in the disinfection chamber 12 is replenished through the liquid replenishing tube.

[0053] The diameters of the two absorbent cotton ropes 13 match the inner diameters of the two disinfection channels, thereby preventing the disinfectant in the disinfection chamber 12 from flowing out when the user turns the detection body 1 upside down.

[0054] The alcohol detector includes an alcohol detection sensor, a display screen 15, and a battery. The alcohol detection sensor is arranged on the detection body 1, and the sensing head of the alcohol detection sensor is located in the detection cavity 14. The display screen 15 is fixed to the side of the detection body 1 and is electrically connected to the alcohol detection sensor. The battery is arranged in the detection body 1 and is electrically connected to the alcohol detection sensor and the display screen 15.

[0055] When the alcohol detection sensor detects the alcohol concentration, it will be displayed on the display screen 15.

[0056] The blow button 35 is provided in the piston channel 36 and is located below the first piston 33 . The blow button 35 is fixedly connected to the detection body 1 and is electrically connected to the display screen 15 .

[0057] When the first piston 33 presses the blowing button 35, the display screen 15 shows that the blowing meets the standard, thereby preventing the person being tested from intentionally not blowing in order to evade the test.

[0058] Working process: When detecting drunk driving, the user lets the person being tested blow air from a blow tube 2, the air flow enters the blow tube 2, and then pushes the corresponding one-way valve plate 24 to rotate, the corresponding one-way valve plate 24 rotates to drive the corresponding linkage rod to rotate outside the linkage groove, and then the air flow enters the detection cavity 14, so that the air pressure in the detection cavity 14 increases, thereby pushing the first piston 33 to move downward to compress the first spring 34 until the first piston 33 presses the blow button 35. When the first piston 33 presses the blow button 35, the display screen 15 shows that the blowing meets the standard, thereby preventing the person being tested from deliberately not blowing air in order to evade the test.

[0059] The first piston 33 drives the piston rod 3 and the pressing rod 37 to move downward, the piston rod 3 drives the two connecting plates 25, the second piston 32, and the fixed tooth 51 to move downward, and the second piston 32 drives the water in the water storage chamber 11 to enter the piston groove 31 through the first channel and the first one-way valve in sequence.

[0060] When the two connecting plates 25 move downward, one of the connecting plates 25 drives the other connecting rod, the one-way valve plate 24 and the air blowing tube 2 to move downward through the connecting groove. When the air blowing tube 2 descends, it moves relative to the absorbent cotton ring 23, so that the absorbent cotton ring 23 fully disinfects the surface of the air blowing tube 2 with disinfectant, thereby preventing cross infection. The disinfectant in the disinfection chamber 12 will continuously replenish the disinfectant in the two absorbent cotton rings 23 through the two absorbent cotton ropes 13.

[0061] When the fixed tooth 51 moves downward and passes through the one-way teeth 52, it pushes the one-way teeth 52, the sliding block 5, and the connecting ring 54 to move outward. After the fixed tooth 51 passes through the one-way teeth 52, the one-way teeth 52, the sliding block 5, and the connecting ring 54 are reset under the action of the second spring 53, so that the fixed tooth 51 and the piston rod 3 can only move downward in one direction.

[0062] When the person being tested finishes blowing, the opened one-way valve sheet 24 rotates under the action of the torsion spring, and the corresponding blowing tube 2 is closed again, so that the airflow in the detection cavity 14 is retained. At this time, the alcohol detection sensor can detect the gas in the detection cavity 14 more stably and permanently, thereby improving the accuracy of alcohol detection. When the alcohol detection sensor detects the alcohol concentration, it will be displayed on the display screen 15.

[0063] After testing a person, the user turns the test body 1 upside down, and then pulls the connecting ring 54, the sliding block 5, the air relief groove 55, and the one-way teeth 52 outward until the air relief groove 55 is exposed, so that the one-way teeth 52 are separated from the fixed teeth 51. Then, the first piston 33 approaches the piston groove 31 under the action of the first spring 34, and the gas in the test cavity 14 flows out from the air relief groove 55. The first piston 33 drives the piston rod 3, the two connecting plates 25, the second piston 32, and the fixed teeth 51 to move toward the piston groove 31, and the connecting plate 25 drives the linkage rod, the one-way valve plate 24, and the air tube 2 to move and reset through the linkage groove. Due to the presence of the torsion spring, the connecting plate 25 can drive the linkage rod, the one-way valve plate 24, and the air tube 2 to move and reset through the linkage groove.

[0064] The second piston 32 pushes the water in the piston groove 31 to be sprayed out through the plurality of second channels, the plurality of second one-way valves, and the plurality of nozzles 22 in sequence, so as to clean the disinfectant on the surface of the sterilized blow tube 2 and clean the saliva on the surface of the blow tube 2 that has just been used.

[0065] If drunk driving is detected, the alcohol gas in the detection cavity 14 needs to be removed before testing the next person to avoid affecting the test results. At this time, the user first pulls the connecting ring 54, the sliding block 5, the air release groove 55, and the one-way teeth 52 outward until the air release groove 55 is exposed, so that the one-way teeth 52 are separated from the fixed teeth 51, and then rotates the connecting ring 54 180 degrees, and the connecting ring 54 drives the sliding block 5, the air release groove 55, and the one-way teeth 52 to rotate 180 degrees, and then releases the connecting ring 54, so that the sliding block 5, the air release groove 55, and the one-way teeth 52 are reset, so that the fixed teeth 51 can only move upward in one direction. Since the air release groove 55 is a circular ring groove, the part of the sliding block 5 where it is located is cylindrical, which can make the sliding block 5 rotate.

[0066] Then the user pushes the pressing rod 37 upward, and the pressing rod 37 drives the first piston 33, the piston rod 3, the two connecting plates 25, the second piston 32, and the fixed teeth 51 to move upward until the first piston 33 is separated from the piston channel 36 and enters the detection cavity 14. The two connecting plates 25 drive the two linkage rods and the two one-way valve plates 24 to rotate through the two linkage grooves to open the two blowing cylinders 2. At this time, the one-way teeth 52 can prevent the first piston 33, the piston rod 3, and the two one-way valve plates 24 from resetting through the fixed teeth 51, thereby maintaining the connection between the inside and outside of the detection cavity 14, so that the alcohol gas in the detection cavity 14 can flow to the outside until the alcohol concentration is not displayed on the display screen 15. And every once in a while, the two blowing cylinders 2 and the inner wall of the detection cavity 14 can be disinfected and cleaned with disinfectant in this state to prevent bacteria from growing.

[0067] Then, after all structures are reset, the next person to be tested is allowed to blow air from another blow tube 2, and the working process is the same as above, thereby realizing the process of automatically and alternately cleaning, disinfecting, and cleaning and disinfecting the saliva on the surfaces of the two blow tubes 2, avoiding cross infection.

[0068] The above embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall all fall within the scope of protection of the present invention.
