[0028] The following further describes the present utility model in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited do not limit the present utility model.

[0029] Embodiment 1

[0030] Referring to Figure 1 、 Figure 2 and Figure 6 as shown, a chemical protection suit with adjustable humidity inside the clothing of the present utility model includes

[0031] Chemical protection suit body 1;

[0032] Humidity adjustment device 2, the humidity adjustment device 2 includes a housing 21 and a drying assembly 22. The housing 21 includes an internal cavity. An air inlet 211 and an air outlet 212 communicating with the cavity are respectively provided at both ends of the housing 21. An air inlet fan 23 and an air outlet fan 24 are respectively arranged in the cavity close to the air inlet 211 and the air outlet 212. The drying assembly 22 includes a plurality of drying nets 221 arranged at intervals between the air inlet fan 23 and the air outlet fan 24. A receiving grid is formed between adjacent drying nets 221 and the housing 21, and each receiving grid is filled with a desiccant 222;

[0033] Connecting pipeline 3, the connecting pipeline 3 includes an air inlet pipe 31 and an air outlet pipe 32. The output end of the air inlet pipe 31 and the input end of the air outlet pipe 32 are respectively connected to the air inlet 211 and the air outlet 212, and the input end of the air inlet pipe 31 and the output end of the air outlet pipe 32 are respectively connected to the chemical protection suit body 1.

[0034] Specifically, the humidity adjustment device 2 communicates with the inside of the chemical protection suit body 1 through the air inlet pipe 31 and the air outlet pipe 32. The operation of the fan of the humidity adjustment device 2 can enable the moist air inside the chemical protection suit body 1 to enter the inside of the humidity adjustment device 2 through the air inlet pipe 31. After the moist air is dried by the drying assembly 22, it is re-transported back to the inside of the chemical protection suit body 1 to realize the cyclic dehumidification of the air, so as to achieve the effect of adjusting the humidity inside the chemical protection suit body 1.

[0035] Specifically, the rotational speeds of the air inlet fan 23 and the air outlet fan 24 can be adjusted, so as to adjust the flow rate and the flow volume of the circulated air inside the chemical protective clothing body 1, thereby setting three dehumidification modes of low, medium, and high gears for the humidity adjustment device 2, and selecting a suitable operation gear according to the relative humidity inside the clothing; at the same time, the operation time of the fan can also be set to realize the continuous operation and intermittent operation modes of the humidity adjustment device 2.

[0036] Specifically, the drying net is detachably connected to the housing, so that the number of accommodation cells and the setting of desiccants can be increased or decreased according to actual needs, thereby realizing the adjustment of the dehumidification capacity of the humidity adjustment device, and making the entire humidity adjustment device have better versatility. At the same time, it can be conceived that the dehumidification capacity of the humidity adjustment device can also be adjusted by increasing or decreasing the filling amount of desiccants in each accommodation cell, and the most suitable adjustment method can be selected according to the actual situation and economy.

[0037] Furthermore, an air inlet switch valve 25 and an air outlet switch valve 26 are respectively arranged on the air inlet 211 and the air outlet 212.

[0038] Furthermore, a first hose ball valve 4 and a second hose ball valve 5 are respectively connected to the armpit and hip bone positions of the chemical protective clothing body 1, and the input end of the air inlet pipe 31 and the output end of the air outlet pipe are respectively connected to the first hose ball valve 4 and the second hose ball valve 5. Specifically, the speed and the flow volume of the air circulation inside the chemical protective clothing body 1 can be adjusted by changing the opening degrees of the air inlet switch valve 25, the air outlet switch valve 26, the first hose ball valve 4 and the second hose ball valve 5, further realizing the adjustment of the dehumidification effect, making the dehumidification speed balance with the evaporation speed of human sweat, and improving the comfort of the chemical protective clothing.

[0039] Furthermore, a water storage grid 6 located below the drying assembly 22 is opened on the bottom surface inside the housing 21, and a highly water-absorbent resin is arranged in the water storage grid 6. Specifically, in order to prevent the calcium chloride desiccant from absorbing moisture and dissolving and leaking, the water storage grid 6 is designed below the drying assembly 22, and the solution after the desiccant absorbs moisture and dissolves can flow into the water storage grid 6 and be absorbed by the highly water-absorbent resin in the water storage grid 6, thereby avoiding the problems of solution shaking and overflow caused by the movement of the wearer.

[0040] Furthermore, two shoulder straps 11 are symmetrically arranged on the back surface of the chemical protective clothing body 1, hook surface magic tapes are arranged on the shoulder straps 11, and loop surface magic tapes 213 respectively matching the hook surface magic tapes on the two shoulder straps 11 are arranged on the housing 21. It can be conceived that the humidity adjustment device 2 and the chemical protective clothing body 1 are connected by magic tapes, and the user can stick the humidity adjustment device 2 at any position on the waist and back. It is very convenient to connect and disassemble, and has high practicability.

[0041] Further, both the intake fan 23 and the exhaust fan 24 include fan blades and a drive source for driving the fan blades to rotate.

[0042] Further, the desiccant 222 includes calcium chloride and 4A molecular sieve.

[0043] Further, the drying net 221 is a metal net. While playing a role in separation, the holes on the drying net 221 can enable the air to have sufficient contact area with the desiccant 222, ensuring the dehumidification effect.

[0044] Embodiment 2

[0045] Refer to Figure 3 、 Figure 4 and Figure 5 As shown, on the basis of Embodiment 1, further, a first four-way valve 7 and a second four-way valve 8 respectively connected to the first hose ball valve 4 and the second hose ball valve 5 are provided in the chemical protective clothing body 1. First internal pipelines 12 extending to the left arm, left hip bone and left calf positions of the chemical protective clothing body 1 are respectively connected to the output ports of the first four-way valve 7, and second internal pipelines 13 extending to the right armpit, back and right calf positions are respectively connected to the output ports of the second four-way valve 8. Specifically, by providing the four-way valve and the internal pipelines, targeted and efficient dehumidification can be carried out on the high-humidity areas inside the chemical protective clothing body 1, ensuring that the inside of the chemical protective clothing has appropriate temperature and humidity, and guaranteeing the comfort and safety of the chemical protective clothing.

[0046] Further, a covering layer covering the first internal pipeline 12 and the second internal pipeline 13 is provided inside the chemical protective clothing body 1. The covering layer is made of a thin and breathable material, which can reduce the influence of the chemical protective clothing on the movement of the wearer and is more beautiful.

[0047] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the creation of the present utility model.
