[0025] See also Figure 1-4 .

[0026] The utility model provides an air quality detection device with an early warning function, comprising a chassis 1 and a detection component 2 connected to one side of the chassis 1, an alarm 3 being provided on the detection component 2, a detection port 4 being provided at the connection between the detection component 2 and the chassis 1, two vents 5 being slidingly provided on the top of the chassis 1, a base 9 being slidingly provided on the bottom of the chassis 1, a rotating seat 10 being rotatably provided on the base 9, an air pump 13 being provided on the rotating seat 10, an air inlet 11 and an air outlet 12 being provided on the rotating seat 10 on both sides of the air pump 13, the air inlet 11 and the air outlet 12 being respectively connected to the two vents 5, two detection tubes 17 being symmetrically provided on the rotating seat 10 and matching the size of the detection port 4, the two detection tubes 17 being both connected to the air pump 13, and the detection tubes 17 being used to pass the gas to be detected sucked in by the air pump 13 into the detection component 2 for detection.

[0027] In addition, a sliding tube 7 is provided above the vent cylinder 5 and is slidably arranged on the top of the chassis 1. A connecting tube 8 is provided at the bottom of the vent cylinder 5 for connecting the vent cylinder 5 and the air inlet 11 or the air outlet 12. The inner diameter of the connecting tube 8 is adapted to the outer diameter of the air inlet 11 or the air outlet 12. That is to say, the connecting tube 8 is sleeved on the air inlet 11 or the air outlet 12 when it is descended. In the specific setting, a sealing device such as a rubber ring can be provided at the bottom of the connecting tube 8 to improve the sealing effect of the device, thereby improving the suction effect of the air pump 13.

[0028] Secondly, a first telescopic rod 19 is provided in the chassis 1, and the protruding end of the first telescopic rod 19 is fixedly connected to the base 9. The first telescopic rod 19 is used to insert the detection tube 17 into the detection port 4 when extended or to pull the detection tube 17 out of the detection port 4 when retracted. A sliding rod 18 is provided on the side of the base 9 away from the first telescopic rod 19. The sliding rod 18 is fixedly connected to the chassis 1. The sliding rod 18 is used to keep the base 9 stable when the base 9 slides. The top of the sliding tube 7 is fixedly connected to the connecting plate 20, and the side of the chassis 1 is fixedly connected to the second telescopic rod 21. The protruding end of the second telescopic rod 21 is fixedly connected to the bottom of the connecting plate 20. The second telescopic rod 21 is used to drive the two sliding tubes 7 to rise when extended to disengage the two connecting tubes 8 from the air inlet 11 or the air outlet 12.

[0029] Furthermore, a plurality of teeth 14 are provided at the bottom of the rotating seat 10, a motor 15 is fixedly connected to the base 9, a gear 16 is fixedly connected to the output end of the motor 15, the gear 16 is meshed with the teeth 14, and the motor 15 is used to drive the rotating seat 10 to rotate under the meshing action of the gear 16 and the teeth 14 when starting. In addition, a filter screen 6 is provided on the top of the sliding tube 7 to prevent debris from being sucked into the air inlet 11, and a baffle 22 is fixedly connected to the end of the base 9 away from the detection port 4. The baffle 22 is used to seal the detection tube 17 away from the detection port 4. That is, when one detection port 4 is used to pass gas from the detection port 4 into the detection component 2, the baffle 22 is used to block the other detection tube 17 that is not connected to the detection port 4.

[0030] When the device is used for detection, the second telescopic rod 21 is first extended, driving the two sliding tubes 7 to rise, so that the two connecting tubes 8 are separated from the air inlet 11 and the air outlet 12, and then the first telescopic rod 19 is retracted to pull the detection tube 17 out of the detection port 4. At this time, the motor 15 is started to rotate the sliding seat until the air inlet 11 rotates to the position where the air outlet 12 was located during the last detection, and then the first telescopic rod 19 and the second telescopic rod 21 are reset in succession, and then the air pump 13 is started to start the air inlet 11 to start intake and the air outlet 12 to start exhaust. At this time, the possible residual gas in the ventilator 5 connected to the air inlet 11 during the last detection will be discharged as the air outlet 12 continues to discharge. As the air pump 13 continues to work, the possible residual gas in the ventilator 5 connected to the air outlet 12 during the last detection will also be discharged. Then the detection component 2 is started for detection, so as to ensure the accuracy of the gas detection.

[0031] Simply put, by rotating the rotating seat 10, the vent cylinder 5 that was used for air intake last time can be used for air outlet during the next test. This can discharge any remaining gas in the air intake cylinder to prevent it from affecting the current or next test. At the same time, as the gas is continuously inhaled and discharged, any remaining gas in the vent cylinder 5 that was used for air outlet last time can also be discharged through the air pump 13. It should be noted that when in use, it is necessary to ensure that the air pump 13 has discharged any remaining gas in the two vent cylinders 5 after working for a period of time before conducting the test.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
