[0002] Filter cotton is usually installed in half masks, full masks or filter cartridges for use, so as to carry out filtration treatment. However, in the actual use process, a life detection device can be used to detect the service life of the filter cotton.

[0003] During the use of the existing detection device, it is usually connected to the filter cartridge, and the air is extracted by a pump body, and the gas components such as the number of particulate matters after filtration and the breathing resistance are detected to judge the use effect and service life of the filter cotton. However, in the actual use process, there are core components such as a pump body, a detection cavity, a particulate matter sensor, a differential pressure sensor, and a flowmeter gas detection sensor inside the detection device. The outer shell is usually connected and fixed by bolts. During the disassembly and maintenance process, it is easy to lose the bolts when disassembling the bolts, and in addition, specific tools are required, and the operation is relatively troublesome.

[0024] Embodiment:

[0025] As Figures 1-5 shown, a field service life detection device for filter cotton includes a first box body 1. A second box body 2 is provided on one side of the first box body 1. Fixed mounting seats 3 are symmetrically provided at both the top and bottom of the first box body 1. The inner sides of the fixed mounting seats 3 are connected with movable deflection arms 4 through positioning shafts. The end of the movable deflection arm 4 located at the top of the first box body 1 is fixedly connected with a connecting and positioning mechanism 5. An air inlet pipe 6 and an air outlet pipe 7 are provided on the top of the second box body 2.

[0026] The working principle of the above technical solution is as follows:

[0027] During use, the movable deflection arm 4 deflects inside the fixed mounting seat 3 so that the movable deflection arm 4 can be sleeved on the outer surface of the second box body 2. Then, under the action of the connecting and positioning mechanism 5, the ends of the movable deflection arms 4 can be connected and fixed, thereby restricting the connection between the first box body 1 and the second box body 2, enabling quick connection and assembly. Conversely, the first box body 1 and the second box body 2 can also be quickly disassembled, and the operation is convenient.

[0028] In another embodiment, as Figure 1 shown, a connecting and protecting mechanism 8 is fixedly connected to the top of the second box body 2.

[0029] It is convenient for the connecting and protecting mechanism 8 to provide stable protection for the air inlet pipe 6 and the air outlet pipe 7 when the whole is not in use, avoiding dust outside from entering the inner parts of the first box body 1 and the second box body 2 through the air inlet pipe 6 and the air outlet pipe 7, which affects the use of the whole.

[0030] In another embodiment, as Figure 1 and Figure 4 shown, fixed limit blocks 9 are symmetrically provided on the surface of the second box body 2.

[0031] When the movable deflection arm 4 is sleeved outside the surface of the second box body 2, the movable deflection arm 4 can be stuck inside the fixed limit block 9, so as to perform a lateral connection limit between the second box body 2 and the movable deflection arm 4, and further perform a lateral connection limit between the first box body 1 and the second box body 2.

[0032] In another embodiment, as Figure 5 shown, the connection and positioning mechanism 5 includes a connection sleeve 10, an activity positioning plug 11 is movably connected inside the connection sleeve 10, a stress sleeve plate 12 is fixedly sleeved on the outer side of the surface of the activity positioning plug 11, a stress spring 13 is fixedly connected between the top of the stress sleeve plate 12 and the inner top end of the connection sleeve 10, and a connection pull block 14 is fixedly connected to the top of the activity positioning plug 11.

[0033] It is convenient to pull the connection pull block 14 upward, drive the activity positioning plug 11 and the stress sleeve plate 12 to move upward, compress the stress spring 13, so that the bottom end of the activity positioning plug 11 can be drawn out from the inner side of the end of the movable deflection arm 4 located at the bottom of the second box body 2, so as to quickly deflect the movable deflection arm 4, and the operation is convenient.

[0034] In another embodiment, as Figure 5 shown, the bottom end edge of the activity positioning plug 11 fits with the inner part of the end of the movable deflection arm 4.

[0035] It is convenient for the end of the activity positioning plug 11 to be stably inserted into the inner side of the end of the movable deflection arm 4, and the operation is convenient.

[0036] In another embodiment, as Figure 3 shown, the connection and protection mechanism 8 includes a suction magnet 15, and a movable protective cover 16 is attracted to the top of the suction magnet 15.

[0037] It is convenient for the movable protective cover 16 to cover the outer sides of the air inlet pipe 6 and the air outlet pipe 7, so that the bottom of the movable protective cover 16 is attracted to the suction magnet 15, so as to stably protect the air inlet pipe 6 and the air outlet pipe 7, and the operation is convenient.

[0038] In another embodiment, as Figure 3 shown, a fixed limit rod 17 is fixedly connected to the top end of the second box body 2, and a fixed through hole 18 is opened at the top end of the movable protective cover 16.

[0039] When the movable protective cover 16 is attracted to the suction magnet 15, it is convenient for the movable protective cover 16 to be sleeved on the outer side of the end surface of the fixed limit rod 17 through the fixed through hole 18, so as to improve the use stability of the movable protective cover 16 and avoid lateral movement, and the operation is convenient.

[0040] Working principle of the utility model: During use, when it is necessary to disassemble between the first box body 1 and the second box body 2 for maintenance of internal components, first pull the connecting pull block 14 upward, driving the movable positioning plug rod 11 and the force-bearing sleeve disc 12 to move upward, compressing the force-bearing spring 13, so that the bottom end of the movable positioning plug rod 11 can be withdrawn from the inner side of the end of the movable deflection arm 4 at the bottom of the second box body 2. Then deflect the movable deflection arm 4 so that the movable deflection arm 4 disengages from the outer side of the surface of the second box body 2 and the inner side of the fixed limit block 9. Then quickly disassemble between the first box body 1 and the second box body 2 for easy maintenance; when the whole is no longer in use, the bottom end of the movable protective cover 16 is attracted to the suction magnet 15, so that the movable protective cover 16 covers the outer sides of the tops of the air inlet pipe 6 and the air outlet pipe 7, and then is sleeved on the outer surface of the top end of the fixed limit rod 17 under the action of the fixed through hole 18, so as to achieve stable connection and prevent external dust from entering the inner sides of the air inlet pipe 6 and the air outlet pipe 7, and the operation is convenient and fast.

[0041] The above embodiments only express the specific implementation manners of the utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation on the patent scope of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the utility model.
