If the specific posture changes, the directional indicator will also change accordingly.

[0023] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0024] Please see Figure 1 , Figure 1 This is a perspective structural diagram of a mobile gas emergency response device provided in one embodiment of this application. The mobile gas emergency response device 1 is used for laboratory safety emergency response. Specifically, the mobile gas emergency response device is used for emergency response to situations such as spillage or spillage of toxic and harmful substances, such as mercury, sulfides, or other organic reagents.

[0025] Please refer to the following: Figure 1 and Figure 2 , Figure 2 for Figure 1The diagram shows an exploded three-dimensional structure of the mobile gas emergency response device. The mobile gas emergency response device 1 includes a housing 10, an air inlet 11, an air outlet 12, a filter device 13, a fan 14, several support devices 15, a flange 17, and a control device 18.

[0026] Several support devices 15 are fixedly connected to one end of the housing 10. Specifically, the support devices 15 are centrally symmetrically distributed about the center line from the top to the bottom of the housing 10 as the axis of symmetry, so that the support devices 15 stably support the housing 10. The air inlet 11 is located at the end of the housing 10 near the support device 15, and the air outlet 12 is located at the end of the housing 10 away from the support device 15. The flange 17 is fixed to the outer surface of the housing 10 corresponding to the air outlet 12. The housing 10 has spaced-apart receiving spaces and receiving portions. The filter device 13 is received in the receiving space 101. Specifically, the outer edge of the filter device 13 abuts against the inner wall of the receiving space 101 to divide the receiving space 101, forming spaced-apart contaminated areas and purified areas. The contaminated area communicates with the outside through the air inlet 11, and the purified area communicates with the outside through the air outlet 12. The control device 18 is partially housed in the receiving portion 103. The fan 14 is housed in the receiving space 101 and is located between the filter device 13 and the air outlet 12. The fan 14 is electrically connected to the control device 18, and the control device 18 switches between different wind speed modes by controlling the motor power of the fan 14. The outer surface of the housing 10 is provided with several grips, specifically, the grips 105 are arranged opposite to each other on both sides of the housing 10.

[0027] In the event of an accidental spill of volatile toxic or hazardous substances, the operator holds the grip 105 to quickly move the portable gas emergency response device 1 to the spill location. Upon power-on, the control device 18 activates the fan 14, creating a pressure difference between the containment space 101 and the external environment. This allows the gaseous volatiles to be drawn into the containment space 101 via the air inlet 11, and after adsorption and decomposition by the filter 13, the gas is discharged from the outlet 12. This emergency response effectively prevents the spread of toxic and hazardous gaseous volatiles within the laboratory.

[0028] Understandably, before power is connected, researchers can connect any pipe to the air outlet 12 via the flange 17, allowing the mobile gas emergency response device 1 to be connected to the laboratory fume hood's duct system, or to any gas collection device, such as an explosion-proof gas cylinder. Thus, after power is connected, the mobile gas emergency response device 1 can achieve targeted collection and pretreatment of toxic and harmful gaseous volatiles, effectively preventing their diffusion within the laboratory and meeting the laboratory's emergency response needs.

[0029] In this embodiment, the support device 15 can be a suction cup type foot. In other embodiments, the support device 15 can also be a bolt-connected foot or a pulley with brakes, etc., which facilitates quick transfer and provides stable support for the housing 10.

[0030] Please see Figure 3 , Figure 3 for Figure 1 The diagram shows a cross-sectional view of the housing 10. The housing 10 includes opposing limiting strips 107, which are disposed on the inner wall of the receiving space 101 corresponding to the filter device 13. The filter device 13 is engaged between the limiting strips 107. The limiting strips 107 are generally L-shaped, including a first limiting portion and a second limiting portion. The first limiting portion 1071 is fixed to the inner wall of the receiving space 101. One end of the second limiting portion 1073 is connected to the first limiting portion 1071, and the other end extends away from the inner wall of the receiving space 101.

[0031] In this embodiment, the gripping part 105 can be a wedge-shaped groove structure, and there are two of them. The two gripping parts 105 are disposed opposite each other on the outer surface of the box body 10, and the depth of the gripping part 105 is less than the thickness of the plate of the box body 10. The inner wall of the gripping part 105 is set at a certain angle relative to the outer surface of the box body 10, so that the area of ​​the groove opening is larger than the area of ​​the groove bottom, which makes it convenient for the experimenter to insert their hands into the gripping part 105 and apply force to hold it. In other embodiments, the gripping part 105 can also be a groove structure or a protrusion structure of other shapes, and there is at least one of them.

[0032] Please see Figure 4 , Figure 4 for Figure 1 The diagram shows a three-dimensional structural view of the mobile gas emergency response device from another perspective. The housing 10 has an opening corresponding to the filter device 13. The centerline of the opening 109 is parallel to the length direction of the limiting strip 107, and the size of the opening 109 is larger than the size of the filter device 13.

[0033] The mobile gas emergency treatment device 1 also includes an opening cover detachably connected to the housing 10. The opening cover 19 is correspondingly provided with the opening 109, and the opening cover 19 is provided with a handle. The experimenter can remove the opening cover 19 by pulling the handle 191, and take out or install the filter device 13 through the opening 109.

[0034] Please refer to the following: Figure 4 and Figure 5 , Figure 5 for Figure 4 The diagram shows a three-dimensional structural representation of the opening cover 19. The opening cover 19 includes a cover body 193 and a neck 195 fixedly connected. The shape of the cover body 193 is configured to fit the opening 109. The end of the neck 195 away from the cover body 193 abuts against the outer surface of the filter device 13. An arbitrary sealing ring (not shown) is fitted onto the neck 195 to achieve an interference fit with the inner wall of the opening 109, ensuring the airtightness of the mobile gas emergency treatment device 1. The handle 191 is located on the side of the cover body 193 away from the neck 195.

[0035] Please refer to the following: Figure 2 The mobile gas emergency handling device 1 further includes a guide plate 16, which comprises a first guide section and a second guide section. The second guide section 163 has a flat plate structure, with one end of the second guide section 163 fixedly connected to the first guide section 161, and the other end extending towards the air outlet 12 to the inner wall of the receiving space 101 and fixedly connected to the inner wall of the receiving space 101. In this embodiment, there are two second guide sections 163, which are respectively fixedly connected to the opposite ends of the first guide section 161.

[0036] The first airflow guide 161 is a flat plate structure with a first side and a second side facing away from each other. The first side faces the air inlet 11, and the second side faces the air outlet 12. The fan 14 is fixedly connected to the first side of the first airflow guide 161. The first airflow guide 161 has a through-hole 1611 that extends from the first side to the second side. The inner diameter of the through-hole 1611 is smaller than the inner diameter of the air duct of the fan 14. The center lines of the air outlet 12, the through-hole 1611, and the fan 14 are aligned.

[0037] The fan 14 is an air booster device comprising a motor, a duct wall, and an impeller. One end of the duct wall is the air inlet, and the opposite end is the air outlet. The air inlet faces the air inlet 11, and the air outlet faces the air outlet 12. The impeller 145 uses centrifugal force to accelerate the processed airflow through the air outlet 12 and discharge it from the housing 10. The motor 141 is electrically connected to the control device 18 via any conductor. The control device 18 controls the start and stop of the fan 14 by powering on or off, and controls the impeller speed of the fan 14 by adjusting the power supply.

[0038] The filtration device 13 includes two opposing and parallel filter screens and a support body fixedly connected to the filter screens 131. The filter screens 131 and the support body 133 cooperate to form a receiving cavity, which is filled with solid filter material 135. The solid filter material 135 can be a mixture of various materials such as broad-spectrum dry chemical reaction filter material, porous adsorption filter material, and glass fiber filter material, or one of them. Of course, it can also be a specially made chemical reaction filter material. There can be multiple filtration devices 13, each filled with different components and proportions of the solid filter material 135. For known spilled substances, different filtration devices 13 can be used for pretreatment based on their physicochemical properties.

[0039] To extend the adsorption and decomposition treatment of gaseous volatiles by the filter device 13, after the airflow passes through the filter device 13, part of the airflow passes through the air duct of the fan 14 and is discharged from the air outlet 12 under the guidance of the guide plate 16; the other part of the airflow, with the cooperation of the first guide section 161 and the air duct wall 143, flows back to the filter device 13. Since the solid filter material 135 is mixed with glass fiber, the airflow diffuses in the filter device 13 to achieve sufficient contact and reaction with the solid filter material 135. Through this backflow filtration design, the situation of insufficient filtration due to excessive airflow velocity can be avoided, resulting in better pretreatment effect of the mobile gas emergency treatment device 1.

[0040] Please refer to the following: Figure 1The control device 18 is partially housed within the receiving portion 103, with another portion protruding from the outer surface of the housing 10. The control device 18 includes a power adapter 181, a control circuit 183, and an operating unit 185. The power interface of the power adapter 181 and the operating unit 185 protrude from the outer surface of the housing 10 for operation or use. The fan 14 is electrically connected to the power adapter 181 via the control circuit 183. The inner wall of the receiving space 101 has several through holes. After the conductor passes through the through holes, insulating glue is used to fill the through holes to ensure the airtightness of the housing 10. The operating unit 185 is electrically connected to the control circuit 183. The experimenter adjusts the voltage of the control circuit 183 by changing the physical state of the operating unit, thereby controlling the impeller speed of the fan 14. In this embodiment, the operating unit 185 is a rotary switch.

[0041] In other embodiments, the control device 18 further includes an energy storage component electrically connected to the power adapter 181. In situations where external power is inconvenient or during power outages, the energy storage component can provide power for the operation of the mobile gas emergency response device 1, improving its convenience and flexibility. The energy storage component is a secondary battery, such as a lithium-ion battery or a lead-acid battery.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
