Summary of the invention

[0009] A transparent plate, the transparent plate is fixedly connected to the inside of the rotating shell and is located in front of the display screen;

[0010] A placement slot is arranged on the front of the portable air detector and on the back of the rotating shell.

[0011] Preferably, a telescopic rod is movably connected inside the placement slot, and the other end of the telescopic rod movably connected to the placement slot is movably connected to the rotating shell.

[0012] Preferably, two second compression springs are fixedly connected to the bottom of the portable air detector, a second rubber roller is provided at the bottom of the portable air detector, and both ends of the second rubber roller are movably connected to the outer ends of the second compression springs respectively.

[0013] Preferably, two first air springs are fixedly connected to the back of the portable air detector, a first rubber roller is arranged on the back of the portable air detector, and two ends of the first rubber roller are respectively movably connected to the outer ends of the first air springs.

[0014] Preferably, an acceleration sensor is fixedly connected to the top of the portable air detector, and a controller is fixedly connected to the top of the portable air detector.

[0015] Preferably, the sound-generating component comprises an elastic cavity, the elastic cavity is fixedly connected to the back of the portable air detector and is located at the bottom of the first air spring, and a plurality of protrusions are fixedly connected to the outer wall of the elastic cavity.

[0016] Preferably, an exhaust pipe is fixedly connected to the bottom of the elastic cavity, a sliding whistle is provided at a corresponding position of the exhaust pipe at the bottom of the exhaust pipe, and a guide rod is fixedly connected to the back of the portable air detector at the bottom of the elastic cavity, and the sliding whistle is movably connected to the outer wall of the guide rod.

[0017] Preferably, the sliding whistle is fixedly connected to a blocking sleeve, the blocking sleeve is movably connected to a connecting rod, the connecting rod is located at the end of the blocking sleeve close to the exhaust pipe and is fixedly connected to an air blocking plate, and the connecting rod is located at the end of the exhaust pipe and is fixedly connected to a limiting plate.

[0018] The present invention provides a portable detection device for air quality detection, which has the following beneficial effects:

[0019] 1. The portable detection device for air quality detection extends the telescopic rod to allow the rotating shell to unfold and form a certain angle with the whole portable air detector. At this time, the rotating shell and the transparent plate are subject to greater wind resistance when falling in the air, causing the portable air detector to deflect as a whole, and the bottom of the portable air detector is inclined to the back and falls toward the ground. When the portable air detector falls to the ground, the second rubber roller contacts the ground first, and the impact force compresses the second compression spring, thereby providing buffer protection for the portable air detector to prevent the equipment from being damaged and affecting the detection.

[0020] 2. The portable detection device for air quality detection absorbs the impact force of the portable air detector hitting the ground through the first air spring, and reduces the impact force between the portable air detector and the ground by converting the momentum of the two rubber rollers falling into horizontal momentum. When the downward momentum of the portable air detector is converted into horizontal momentum, the rotating shell and the transparent plate will still increase the wind resistance during movement, so that the horizontal momentum becomes smaller under the action of wind resistance, so that the portable air detector can stop quickly to prevent it from colliding again due to horizontal movement, so as to protect the equipment and prevent the equipment from being damaged and affecting the detection.

[0021] 3. The portable detection device for air quality detection, when holding the portable air detector by hand, the hand will fit against the outer wall of the elastic cavity, and the protrusion will fit against the gap between the fingers, which can enable people to better fix and hold the portable air detector, improve the comfort of holding, and prevent the portable air detector from falling off the hand.

[0022] 4. In the portable detection device for air quality detection, when the first air spring is compressed, the elastic cavity will also be compressed to discharge gas, which plays a role of buffering and protecting the portable air detector, and allows the protrusion to fit with the ground. Under the action of the buffer mechanism, when the momentum of the portable air detector falls to the horizontal momentum, the protrusion will generate friction with the ground, thereby quickly stopping the portable air detector, so that people can easily find the fallen portable air detector to continue testing.

[0023] 5. The portable detection device for air quality detection will discharge the gas at the back through the exhaust pipe when the elastic cavity is compressed. The discharged gas will push the gas blocking plate, and then push the sliding whistle outward through the gas blocking plate to allow the internal gas to be discharged quickly, and the discharge direction is opposite to the movement direction of the portable air detector, which is beneficial to reduce the momentum of the portable air detector in the moving direction, so that the portable air detector can be stopped faster, so that people can easily find the fallen portable air detector to continue the detection.

[0024] 6. The portable detection device for air quality detection restores its deformation through the elastic cavity, and when inhaling air, part of the sliding whistle will be sucked into the exhaust pipe. The atmospheric pressure will move the air blocking piece toward the elastic cavity. At this time, there will be a smaller space between the outer side of the air blocking piece and the inner wall of the exhaust pipe to allow air flow. The gas will make a sound when passing through the sliding whistle, and because of the size of the opening that limits the flow of gas, the sliding whistle can make a sound for a longer time, so that the user can find the portable air detector more quickly after it falls, and it is easy for people to find the fallen portable air detector to continue testing.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0036] Embodiment 1

[0037] See also Figure 1-4 The present invention provides a technical solution: a portable detection device for air quality detection, comprising a portable air detector 1, a ventilation detection port 2 is fixedly connected to the front of the portable air detector 1, a display screen 4 is fixedly connected to the front of the portable air detector 1, an interactive button 3 is fixedly connected to the front of the portable air detector 1, a buffer mechanism 5 is movably connected to the front of the portable air detector 1, and a sounding component 6 is fixedly connected to the back of the portable air detector 1;

[0038] The buffer mechanism 5 comprises:

[0039] A rotating shell 501, wherein the rotating shell 501 is movably connected to the front side of the portable air detector 1;

[0040] A transparent plate 502, which is fixedly connected to the inside of the rotating shell 501 and is located in front of the display screen 4;

[0041] The placement slot 504 is arranged on the front side of the portable air detector 1 and on the back side of the rotating shell 501 .

[0042] A telescopic rod 503 is movably connected inside the placement groove 504 , and the other end of the telescopic rod 503 movably connected to the placement groove 504 is movably connected to the rotating shell 501 .

[0043] Two second compression springs 509 are fixedly connected to the bottom of the portable air detector 1 . A second rubber roller 510 is arranged at the bottom of the portable air detector 1 , and both ends of the second rubber roller 510 are movably connected to the outer ends of the second compression springs 509 .

[0044] Two first air springs 507 are fixedly connected to the back of the portable air detector 1 . A first rubber roller 508 is arranged on the back of the portable air detector 1 , and both ends of the first rubber roller 508 are movably connected to the outer ends of the first air springs 507 .

[0045] An acceleration sensor 505 is fixedly connected to the top of the portable air detector 1 , and a controller 506 is fixedly connected to the top of the portable air detector 1 .

[0046] When in use, use one hand to hold the portable air detector 1 with the ventilation detection port 2 located below the display screen 4, and use the interactive button 3 to control the portable air detector 1 to detect the air through the ventilation detection port 2. The detected structure will be displayed on the display screen 4. When the device falls off the hand, the device will obtain the acceleration from gravity, which will be captured by the acceleration sensor 505. At this time, the telescopic rod 503 is quickly extended through the control of the controller 506, and when there is no resistance to the extension of the telescopic rod 503, it continues to extend until the telescopic rod 503 is extended to the limit. The rotating shell 501 will unfold and form a certain angle with the portable air detector 1 as a whole. At this time, the rotating shell 501 and the transparent plate 502 fall in the air, causing the portable air detector 1 to be subjected to greater wind resistance on one side of the rotating shell 501, causing the portable air detector 1 to deflect as a whole, and causing the bottom of the portable air detector 1 to fall toward the ground in the direction of the back. When the portable air detector 1 falls to the ground, the second rubber roller 510 will first contact the ground, and the impact force will compress the second compression spring 509, thereby providing buffering protection for the portable air detector 1.

[0047] After buffering, since the portable air detector 1 is in a relatively inclined state, the back of the portable air detector 1 is gradually in contact with the ground with the second rubber roller 510 as the rotation point, and the momentum of the fall in this process will cause the portable air detector 1 to start rolling to the corresponding side through the second rubber roller 510, while the back of the portable air detector 1 is in contact with the ground. In the process of the back of the portable air detector 1 being in contact with the portable air detector 1, the first air spring 507 will be compressed by the first rubber roller 508 to absorb the impact force of the portable air detector 1 hitting the ground, and the first rubber roller 508 can roll with the surface of the portable air detector 1, which can facilitate the conversion of the falling momentum into horizontal momentum to reduce the impact force between the portable air detector 1 and the ground. When the downward momentum of the portable air detector 1 is converted into horizontal momentum, the rotating shell 501 and the transparent plate 502 will still increase the wind resistance during movement, so that the horizontal momentum becomes smaller under the action of wind resistance, so that the portable air detector 1 stops quickly to prevent it from colliding again due to horizontal movement.

[0048] Embodiment 2

[0049] See also Figure 1-8 Based on the first embodiment, the present invention provides a technical solution:

[0050] The sound-generating component 6 includes an elastic cavity 601 , which is fixedly connected to the back of the portable air detector 1 and located at the bottom of the first air spring 507 . A plurality of protrusions 602 are fixedly connected to the outer wall of the elastic cavity 601 .

[0051] An exhaust pipe 603 is fixedly connected to the bottom of the elastic cavity 601, and a sliding whistle 605 is arranged at a corresponding position of the exhaust pipe 603. The back of the portable air detector 1 is located at the bottom of the elastic cavity 601 and is fixedly connected to a guide rod 604, and the sliding whistle 605 is movably connected to the outer wall of the guide rod 604.

[0052] A blocking sleeve 609 is fixedly connected inside the sliding whistle 605, and a connecting rod 607 is movably connected inside the blocking sleeve 609. The connecting rod 607 is located at one end of the blocking sleeve 609 close to the exhaust pipe 603 and is fixedly connected to an air blocking plate 606. The connecting rod 607 is located at one end of the exhaust pipe 603 away from the air blocking plate 606 and is fixedly connected to a limiting plate 608.

[0053] During use, when holding the portable air detector 1 with the hand, the hand will fit against the outer wall of the elastic cavity 601, and the protrusion 602 will fit against the gap between the fingers, which can enable people to better fix and hold the portable air detector 1, improve the comfort of holding, and prevent the portable air detector 1 from falling off the hand.

[0054] When the portable air detector 1 falls off from the hand and the first air spring 507 is compressed, the elastic cavity 601 will also be compressed to discharge gas, thereby providing buffering protection for the portable air detector 1 and allowing the protrusion 602 to fit the ground. When the momentum of the portable air detector 1 falling is horizontal under the action of the buffer mechanism 5, the protrusion 602 will generate friction with the ground, thereby quickly stopping the portable air detector 1, allowing people to easily find the fallen portable air detector 1 to continue testing.

[0055] When the elastic cavity 601 is compressed, the gas at the back will be discharged through the exhaust pipe 603, and the discharged gas will push the air blocking sheet 606, and then push the sliding whistle 605 outward through the air blocking sheet 606, so that the internal gas can be discharged quickly, and the discharge direction is opposite to the movement direction of the portable air detector 1, which is beneficial to reduce the momentum of the portable air detector 1 in the moving direction, so that the portable air detector 1 can stop faster.

[0056] After the impact of the portable air detector 1 on the bottom disappears, the elastic cavity 601 will restore its deformation due to its own elasticity, thereby reducing the gas pressure inside the elastic cavity 601 and inhaling air. When inhaling gas, part of the sliding whistle 605 will be sucked into the exhaust pipe 603, and because the outer side of the sliding whistle 605 is restricted and cannot enter the exhaust pipe 603, the air blocking plate 606 will be pressed toward the side of the elastic cavity 601 by the atmospheric pressure until the limiting plate 608 cannot pass through the blocking sleeve 609 to limit the position of the limiting plate 608. At this time, there will be a smaller space between the outer side of the air blocking plate 606 and the inner wall of the exhaust pipe 603 for air flow, and the gas will make a sound when passing through the sliding whistle 605. Due to the size of the opening that limits the gas flow, the sliding whistle 605 can make a sound for a longer time, allowing the user to find the portable air detector 1 faster after the portable air detector 1 falls.

[0057] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
