Description

Technical Field

[0001] The utility model relates to the technical field of air collection and pollution detection, in particular to a gas collection mechanism and a gas detection device thereof. Background Art

[0002] The existing gas detection device inhales external gas through the exhaust hole on the cabinet, but there is a problem that the detected gas is retained in the cabinet and cannot be discharged in time. At the same time, the detected gas must first enter the cabinet and then reach the gas detection device through the air inlet, resulting in repeated detection of the gas in the cabinet, which reduces the detection accuracy.

[0003] Therefore, it is very important to propose a new gas collection mechanism, which can directly collect the gas outside the cabinet and send it to the air inlet, so that the gas detection device can directly detect the external gas, avoiding repeated detection of the gas inside the cabinet, thereby improving the detection accuracy.

[0033] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1

[0037] Reference Figures 1 to 6 , which is the first embodiment of the utility model, and this embodiment provides a gas collection mechanism.

[0038] Specifically, the gas collection unit 100 includes an air intake assembly 101, a power assembly 102 arranged inside the air intake assembly 101, a linkage assembly 103 arranged at one end of the power assembly 102 and meshing with gears, a beveled gear plate 104 arranged at one side of the power assembly 102 and meshing with gears, an air guide tube 105 arranged at the bottom of the air intake assembly 101, and a gas sampling assembly 106 arranged on the air guide tube 105.

[0039] Further, the air intake assembly 101 includes a cover 101a, an air intake pipe 101b fixedly connected to the inside of the cover 101a, a support frame 101c fixedly connected to the inside of the air intake pipe 101b, a fan blade 101d movably connected to the support frame 101c, a semi-tooth transmission component 101e fixedly connected to one end of the fan blade 101d, and a filter screen 101f arranged on the outside of the air intake pipe 101b;

[0040] The fan blade 101d can only rotate within the bracket 101c and cannot move axially.

[0041] Furthermore, the power assembly 102 includes a motor 102a fixedly connected to the inside of the air intake assembly 101, a transmission rod 102b arranged at one end of the motor 102a, a first gear 102c fixedly connected to the transmission rod 102b, and a second gear 102d fixedly connected to one end of the transmission rod 102b.

[0042] Preferably, the linkage assembly 103 includes a third gear 103a meshed with the first gear 102c, a first fixing seat 103b fixedly connected to the inner surface of the air intake assembly 101, a fourth gear 103c meshed with the third gear 103a, and a transmission shaft 103d fixedly connected to the fourth gear 103c;

[0043] The first fixing seat 103b is movably connected to the third gear 103a.

[0044] Furthermore, a groove 103d-1 is formed on the outer surface of the transmission shaft 103d, and a guide platform 103d-2 is arranged on the surface of the transmission shaft 103d.

[0045] More preferably, as a preferred solution of the gas collecting mechanism of the utility model, wherein: a limited seat 103e is fixedly installed inside the air intake component 101, and a second fixed seat 104b is also fixedly installed inside the air intake component 101.

[0046] The transmission shaft 103d is movably connected and installed in the limit position 103e.

[0047] It should be noted that the bevel gear plate 104 is meshed with the second gear 102d, and the bevel gear plate 104 is provided with a guide bevel 104a;

[0048] The second fixing seat 104 b is movably connected to the bevel gear plate 104 .

[0049] When in use, the motor 102a is started, so that the transmission rod 102b drives the first gear 102c and the second gear 102d to rotate, and the third gear 103a is driven to rotate through the first gear 102c, and then the fourth gear 103c is driven to rotate. At this time, the transmission shaft 103d is also driven to start rotating, so that the half-tooth transmission head at one end of the transmission shaft 103d is combined with the half-tooth transmission component 101e fixedly connected to the fan blade 101d, so that the fan blade 101d rotates, thereby sucking in outdoor air;

[0050] The second gear 102d then rotates to drive the bevel gear plate 104 to rotate. Since the bevel gear plate 104 is provided with a guide bevel 104a, when the bevel gear plate 104 rotates, the guide bevel 104a will touch the guide platform 103d-2, causing the transmission shaft 103d to shift, so that the half-tooth transmission head on the transmission shaft 103d will be separated from one of the fan blades 101d. At this time, only one fan blade 101d will rotate to inhale the air on one side. When the second gear 102d continues to rotate, the bevel gear plate 104 can touch the other side of the guide platform 103d-2 through the guide bevel 104a, so that the transmission shaft 103d is combined with the other fan blade 101d, and the left and right fan blades 101d repeatedly work back and forth to inhale the gas on the left and right sides respectively.

[0051] In summary, the transmission shaft 103d is displaced back and forth left and right through the bevel gear plate 104, so that the left and right fan blades 101d work reciprocatingly, and the gas on both sides is sucked in respectively, thereby increasing the gas collection range.

[0052] Example 2

[0053] Reference Figure 3, which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a gas sample retention component 106.

[0054] Specifically, the gas sample retaining assembly 106 includes a one-way valve 106 - 1 connected to one end of the gas guide tube 105 , and a gas storage tank body 106 - 2 arranged on one side of the one-way valve 106 - 1 .

[0055] Among them, a one-way valve 106-1 is provided at both ends of the tank body 106-2.

[0056] In summary, when in use, the gas is transported to the gas sample retention component 106 through the air guide tube 105, and the two one-way valves 106-1 are set to retain gas in the gas storage tank body 106-2. When it is necessary to retain the sample, just remove the gas storage tank body 106-2 and replace it with a new one.

[0057] Example 3

[0058] Reference Figures 1 to 3 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides a gas detection device.

[0059] Specifically, the gas detection device 200 includes a gas detection component 201, a pre-filter component 202 arranged on the outer surface of the gas detection component 201, a cabinet 203 installed at the bottom of the air intake component 101, and an exhaust hole 203-1 opened on the outer surface of the cabinet 203.

[0060] Furthermore, the air duct 105 is connected to the pre-filter assembly 202 .

[0061] In summary, when in use, the gas is inhaled through the air intake component 101, and the gas is transported to the pre-filter component 202 through the air duct 105. The larger impurities in the gas are filtered out by the pre-filter component 202 and then provided to the gas detection component 201 for detection, thereby improving the accuracy and service life of the gas detection component 201.
