[0002] In existing surgical operations, surgical smoke is generated when using active instruments such as ultrasonic scalpels or electrocautery to cut tissues. To avoid the pollution of the operating room by surgical smoke, medical air extraction devices such as smoke exhaust devices and negative pressure suction devices are usually used to suck the air in the operating room. After filtering the surgical smoke through the filter module in the medical air extraction device, the filtered air is discharged into the operating room.

[0003] Surgical smoke usually contains a large amount of water vapor. To avoid the influence of water vapor on the service life of the filter module, the medical air extraction device can also include a water vapor collection device, which is located upstream of the filter module. When the air containing surgical smoke in the operating room is sucked into the medical air extraction device, the air will first enter the water vapor collection device, and the liquid in the air will sink to the liquid collection cavity in the water vapor collection device under the action of gravity, and then flow to the filter module for filtration.

[0043] The embodiments of the present application provide a water vapor collection device and a medical air extraction device. The following will be described in detail separately.

[0044] First, the embodiments of the present application provide a water vapor collection device.

[0045] Figure 1 It is a schematic structural diagram of an embodiment of the water vapor collection device provided by the embodiments of the present application. Figure 2 is Figure 1 the sectional view along the A-A direction in. As Figure 1 and Figure 2As shown in the figure, the water vapor collection device 100 includes a housing 110 and a first partition 112. The first partition 112 is disposed inside the housing 110 and encloses at least part of the housing 110 to form a liquid collection cavity 111. The housing 110 further includes an air inlet 1101 and an air outlet 1102, and the air inlet 1101 and the air outlet 1102 are respectively communicated with the liquid collection cavity 111. Thus, when the water vapor collection device 100 is used in a medical air extraction device, the air containing surgical smoke in the operating room can be absorbed into the liquid collection cavity 111 through the air inlet 1101 of the water vapor collection device 100, so that the water vapor in the air sinks into the liquid collection cavity 111 under the action of gravity, and then is discharged from the air outlet 1102.

[0046] Wherein, the housing 110 of the water vapor collection device 100 may further include a buffer cavity 113. A first communication port 1121 is opened on the first partition 112, and the liquid collection cavity 111 is communicated with the buffer cavity 113 through the first communication port 1121. The air outlet 1102 is communicated with the buffer cavity 113, so that the air outlet 1102 is communicated with the liquid collection cavity 111. Moreover, in the height direction Z of the water vapor collection device 100, there is a certain height distance between the lowest point of the first communication port 1121 and the bottom surface of the liquid collection cavity 111.

[0047] The water vapor collection device 100 provided by the embodiment of the present application is provided with a buffer cavity 113 in the housing 110, so that the liquid collection cavity 111 is communicated with the buffer cavity 113 through the first communication port 1121 opened on the first partition 112, and there is a certain height distance between the lowest point of the first communication port 1121 and the bottom surface of the liquid collection cavity 111 in the height direction Z of the water vapor collection device 100, so that a certain amount of liquid can be deposited in the liquid collection cavity 111. At the same time, when the water vapor collection device 100 shakes, the liquid overflowing from the first communication port 1121 in the liquid collection cavity 111 will flow into the buffer cavity 113, rather than directly flowing to the filter module 119 (as Figure 6 shown). Therefore, when the water vapor collection device 100 shakes, the risk that the liquid overflowing from the liquid collection cavity 111 flows to the filter module 119 and affects the service life of the filter module 119 can be reduced.

[0048] It should be noted that the height direction Z of the water vapor collection device 100 refers to the distribution direction of the top and the top of the water vapor collection device 100 during normal use, and is perpendicular to the horizontal direction.

[0049] In addition, the lowest point of the first communication port 1121 refers to the point with the lowest height on the edge of the first communication port 1121 in the height direction Z of the water vapor collection device 100. In the height direction Z of the water vapor collection device 100, the height distance between the lowest point of the first communication port 1121 and the bottom surface of the liquid collection cavity 111 can be determined according to factors such as the structure of the liquid collection cavity 111 and the rated volume of the liquid collection cavity 111.

[0050] In some embodiments, in the height direction Z of the water vapor collection device 100, the height of the lowest point of the first communication port 1121 on the first partition plate 112 can be made greater than the rated liquid level height in the liquid collection cavity 111. Thus, as much liquid as possible can be accommodated in the liquid collection cavity 111. At the same time, a greater height distance is provided between the lowest point of the first communication port 1121 and the liquid level height in the liquid collection cavity 111, so as to reduce the probability that the liquid overflowing from the liquid collection cavity 111 flows into the buffer cavity 113. Therefore, when the water vapor collection device 100 shakes, the risk that the liquid overflowing from the liquid collection cavity 111 flows to the filtration module 119 and affects the service life of the filtration module 119 is further reduced.

[0051] It should be noted that the rated liquid level height in the liquid collection cavity 111 can be the height of the liquid level when the liquid volume in the liquid collection cavity 111 reaches the rated volume or the safety volume of the liquid collection cavity 111. Or, the rated liquid level height in the liquid collection cavity 111 can be the height of the maximum scale value on the inner surface of the liquid collection cavity 111.

[0052] Continue to refer to Figure 2 , the liquid collection cavity 111 and the buffer cavity 113 are distributed along the first direction X. The plate surface of the first partition plate 112 forms an angle with the first direction X, and the first direction X is perpendicular to the height direction Z of the water vapor collection device 100. Among them, the first communication port 1121 can be opened at one end of the first partition plate 112 away from the bottom surface of the liquid collection cavity 111 along the height direction Z of the water vapor collection device 100. That is, the first communication port 1121 is opened at the top end of the first partition plate 112 along the height direction Z of the water vapor collection device 100. Thus, the height of the lowest point of the first communication port 1121 can be increased as much as possible, and the height distance between the lowest point of the first communication port 1121 and the liquid level in the liquid collection cavity 111 can be made as large as possible, so as to further reduce the probability that the liquid overflowing from the liquid collection cavity 111 flows into the buffer cavity 113.

[0053] In some embodiments, such as Figure 2As shown, the housing 110 may further include at least one second partition 1133, and the at least one second partition 1133 divides the buffer chamber 113 into at least two sub-chambers 1131 that are sequentially connected from the first communication port 1121 to the air outlet 1102. Adjacent two sub-chambers 1131 are connected through a second communication port 1134 provided on each second partition 1133. The liquid overflowing from the first communication port 1121 of the liquid collection chamber 111 needs to flow through at least two sub-chambers 1131 of the buffer chamber 113 in sequence before flowing out from the outlet 1213 of the buffer chamber 113.

[0054] Wherein, in the height direction Z of the water vapor collection device 100, there is a certain height distance between the lowest point of the second communication port 1134 and the bottom surface of the corresponding sub-chamber 1131. Thus, each sub-chamber 1131 has a certain capacity. When the liquid level height in the sub-chamber 1131 reaches the height of the lowest point of the second communication port 1134, the liquid in the sub-chamber 1131 will flow through the second communication port 1134 to the next sub-chamber 1131, which is beneficial to reducing the risk of the liquid in the buffer chamber 113 overflowing from the outlet 1213 of the buffer chamber 113.

[0055] It should be noted that the second communication port 1134 corresponds to the upstream-connected sub-chamber 1131. The second communication port 1134 corresponding to the sub-chamber 1131 can be used as the outlet 1213 of the sub-chamber 1131, and the liquid in the sub-chamber 1131 can flow through the corresponding second communication port 1134 to the next sub-chamber 1131. In the height direction Z of the water vapor collection device 100, the greater the height distance between the lowest point of the second communication port 1134 and the bottom surface of the corresponding sub-chamber 1131, the greater the volume of the liquid that can be accommodated in the sub-chamber 1131 corresponding to the second communication port 1134.

[0056] Continue to refer to Figure 2 , the second communication port 1134 can be opened at one end of the second partition 1133 away from the bottom surface of the corresponding sub-chamber 1131 along the height direction Z of the water vapor collection device 100. That is, the second communication port 1134 is opened at the top end of the second partition 1133 along the height direction Z of the water vapor collection device 100. Thus, the height of the lowest point of the second communication port 1134 can be increased as much as possible, and the height distance between the lowest point of the second communication port 1134 and the liquid level in the corresponding sub-chamber 1131 can be made as large as possible, so as to further reduce the risk of the liquid in the buffer chamber 113 overflowing from the outlet 1213 of the buffer chamber 113.

[0057] In some embodiments, the second communication port 1134 closest to the first communication port 1121 can be arranged out of alignment with the first communication port 1121 in a direction perpendicular to the distribution direction of the two sub-chambers 1131 connected by the current second communication port 1134, so that the air flow directions in the two sub-chambers 1131 connected by the second communication port 1134 are opposite. This arrangement of the sub-chambers 1131 can make the distribution of the multiple sub-chambers 1131 of the buffer chamber 113 more compact while maximizing the distance between the first communication port 1121 and the adjacent downstream second communication port 1134, or maximizing the distance between two adjacent second communication ports 1134, which helps to reduce the liquid splashed from the upstream first communication port 1121 or second communication port 1134 onto the adjacent downstream second communication port 1134.

[0058] Moreover, it can also make the distance that air flows in each sub-chamber 1131 as long as possible, which helps the water vapor remaining in the air in the sub-chamber 1131 to sink to the inside of the sub-chamber 1131 under the action of gravity, so as to further improve the dryness of the air, thereby further reducing the impact of water vapor on the service life of the filter module 119.

[0059] Specifically, the second communication port 1134 closest to the first communication port 1121 is located at one end in the width direction of the corresponding second partition 1133, while the first communication port 1121 corresponds to the position at the other end in the width direction of the second partition 1133, so as to maximize the distance between the first communication port 1121 and the adjacent downstream second communication port 1134. One side plate surface of the second partition 1133 is perpendicular to the first direction X, and the width direction of the second partition 1133, the first direction X, and the height direction Z of the water vapor collection device 100 are perpendicular to each other.

[0060] Of course, as Figure 4 shown, one side plate surface of the second partition 1133 can also be parallel to the first direction X and the height direction Z of the water vapor collection device 100, and the width direction of the second partition 1133 is parallel to the first direction X.

[0061] In some embodiments, the number of the second partitions 1133 can be one, and the second partition 1133 divides the buffer chamber 113 into two sub-chambers 1131. Among them, the second communication port 1134 on the second partition 1133 is located at one end of the second partition 1133 away from the first communication port 1121 in the width direction, and the outlet 1213 of the downstream sub-chamber 1131 is away from the first communication port 1121 in the width direction of the second partition 1133, so that the air flow directions in two adjacent sub-chambers 1131 are opposite.

[0062] Of course, the number of the second partition plates 1133 can also be two, three or more. When the number of the second partition plates 1133 is plural, the plural second partition plates 1133 are arranged at intervals relative to each other in sequence in the buffer chamber 113, so as to divide the buffer chamber 113 into a plurality of sub-chambers 1131. Two second communication ports 1134 communicated with the same sub-chamber 1131 are arranged in a staggered manner along the width direction of the second partition plate 1133, so that the air flow directions in two adjacent sub-chambers 1131 are opposite. Among them, the second communication port 1134 corresponding to the sub-chamber 1131 located at the most upstream (the sub-chamber 1131 closest to the liquid collecting chamber 111) is arranged in a staggered manner with the first communication port 1121 along the width direction of the second partition plate 1133, and the second communication port 1134 farthest from the liquid collecting chamber 111 is arranged in a staggered manner with the outlet 1213 of the sub-chamber 1131 located at the most downstream (the sub-chamber 1131 farthest from the liquid collecting chamber 111) along the width direction of the second partition plate 1133.

[0063] In other embodiments, the liquid collecting chamber 111 and the buffer chamber 113 can be distributed along the first direction X. A third communication port 1132 communicated with the air outlet 1102 is formed on the inner side surface 1110 of the buffer chamber 113. The third communication port 1132 is located on the side of the buffer chamber 113 away from the liquid collecting chamber 111 along the first direction X, so that the air in the buffer chamber 113 is discharged from the air outlet 1102 after passing through the third communication port 1132.

[0064] Among them, the first communication port 1121 and the third communication port 1132 can be arranged in a staggered manner in the second direction Y, and the first direction X, the second direction Y and the height direction Z of the water vapor collecting device 100 are perpendicular to each other. By arranging the third communication port 1132 of the buffer chamber 113 and the first communication port 1121 of the liquid collecting chamber 111 in a staggered manner in the second direction Y, the distance between the first communication port 1121 and the third communication port 1132 can be increased as much as possible, which is beneficial to reducing the risk that the liquid overflowing from the first communication port 1121 splashes onto the third communication port 1132 and flows out from the third communication port 1132.

[0065] Among them, the buffer chamber 113 can be a complete cavity. Alternatively, the buffer chamber 113 can also be a plurality of sub-chambers 1131 formed by being separated by at least one second partition plate 1133, and the sub-chamber 1131 located at the most downstream or farthest from the liquid collecting chamber 111 is communicated with the third communication port 1132.

[0066] In addition, there is a certain height distance between the lowest point of the third communication port 1132 and the bottom surface of the buffer chamber 113, so that a certain amount of liquid can be accommodated in the buffer chamber 113.

[0067] In some embodiments, such as Figure 6As shown, the housing 110 may further include a filtering chamber 114 that communicates between the buffer chamber 113 and the air outlet 1102, and a filtering module 119 is provided in the filtering chamber 114. Thus, the air flowing from the buffer chamber 113 into the filtering chamber 114 can be filtered by the filtering module 119, thereby enabling the water vapor collection device 100 to integrate the functions of water vapor collection and filtration of the air containing surgical smoke.

[0068] Wherein, a third communication port 1132 is formed on the inner peripheral surface of the buffer chamber 113, and the third communication port 1132 communicates with the air outlet 1102 through the filtering chamber 114, so that the gas in the buffer chamber 113 first passes through the filtering chamber 114 and then is discharged from the air outlet 1102.

[0069] There is a certain height distance between the lowest point of the third communication port 1132 and the bottom surface of the buffer chamber 113 to reduce the risk that the liquid in the buffer chamber 113 enters the filtering chamber 114 through the third communication port 1132 and damages the filtering module 119 in the filtering chamber 114.

[0070] In some embodiments, the third communication port 1132 and the air outlet 1102 may be distributed on both sides of the filtering module 119, so that the air flowing out of the third communication port 1132 can be filtered by the filtering module 119 first and then discharged from the air outlet 1102.

[0071] In other embodiments, as Figure 5 and Figure 6 shown, the water vapor collection device 100 may further include a first control valve 120 connected to the housing 110, and the first control valve 120 is used to control the opening or closing of the first communication port 1121. Thus, when the water vapor collection device 100 absorbs the air containing surgical smoke, the first control valve 120 can be controlled to open the first communication port 1121 so that the air containing surgical smoke can flow through the liquid collection chamber 111 and the buffer chamber 113 in sequence. When the water vapor collection device 100 does not absorb the air containing surgical smoke, the first control valve 120 can be controlled to close the first communication port 1121 to prevent the liquid in the liquid collection chamber 111 from overflowing from the first communication port 1121.

[0072] Among them, the first control valve 120 can include a valve body 121, a push rod 122, and a valve core 123. The valve body 121 is connected to the housing 110. The valve body 121 includes an inlet 1212 and an outlet 1213 that communicate with each other. The inlet 1212 of the valve body 121 communicates with the first communication port 1121, and the outlet 1213 of the valve body 121 is used to communicate with the buffer chamber 113. The valve core 123 is arranged on the push rod 122, and the push rod 122 is movably connected to the valve body 121 or the housing 110. When the push rod 122 moves relative to the valve body 121 or the housing 110, it can drive the valve core 123 to move synchronously. Among them, the push rod 122 is used to drive the valve core 123 to move relative to the valve body 121 under the drive of an external drive mechanism, so that the valve core 123 opens or closes the outlet 1213 of the valve body 121.

[0073] Thus, the push rod 122 can be driven by an external drive mechanism to move relative to the valve body 121 or the housing 110, so as to drive the valve core 123 to move relative to the valve body 121, and the valve core 123 opens or closes the outlet 1213. When the valve core 123 opens the outlet 1213 of the valve body 121, the first communication port 1121 of the liquid collection chamber 111 can be kept in communication with the buffer chamber 113 through the inlet 1212 and the outlet 1213 of the valve body 121. When the valve core 123 closes the outlet 1213 of the valve body 121, the first communication port 1121 of the liquid collection chamber 111 and the buffer chamber 113 are kept isolated to prevent the liquid in the liquid collection chamber 111 from overflowing from the first communication port 1121.

[0074] It should be noted that the push rod 122 and the valve body 121 or the housing 110 can be slidably connected or rotatably connected, as long as when the push rod 122 moves relative to the valve body 121 or the housing 110, it can drive the valve core 123 to move relative to the valve body 121 between the positions of opening or closing the outlet 1213.

[0075] Among them, as Figure 6 shown, a through hole 1211 can be opened in the valve body 121. The inlet 1212 of the valve body 121 is opened on the inner peripheral surface of the through hole 1211. One end of the through hole 1211 communicates with the outlet 1213 of the valve body 121, so that the through hole 1211 of the valve body 121 connects the inlet 1212 and the outlet 1213. The push rod 122 is slidably connected to the valve body 121 or the housing 110 along the length direction of the through hole 1211. When the push rod 122 slides relative to the valve body 121 or the housing 110, it can drive the valve core 123 to slide along the length direction of the through hole 1211 to open or close the outlet 1213 of the valve body 121.

[0076] Continue to refer to Figure 6The valve body 121 further includes a second opening 1214 connected to the other end of the through hole 1211, and the first control valve 120 further includes a flexible seal 124 connected to the valve body 121 or the housing 110, the flexible seal 124 seals the second opening 1214, and the flexible seal 124 includes an abutment portion 1241, the abutment portion 1241 is used to abut against one end of the push rod 122 close to the second opening 1214. Thus, the second opening 1214 of the valve body 121 can be kept closed by the flexible seal 124 to prevent air from leaking out of the second opening 1214 of the valve body 121, and the external driving mechanism can also easily apply a force to the abutment portion 1241 of the flexible seal 124 to drive the push rod 122 to slide relative to the valve body 121 or the housing 110.

[0077] The push rod 122 can be passed through the outlet 1213 of the valve body 121, so that the push rod 122 is movably connected to the housing 110. Specifically, the housing 110 includes a mounting portion 115 located at a side of the outlet 1213 of the valve body 121 away from the second opening 1214, and the push rod 122 passes through the outlet 1213 of the valve body 121 and is slidably connected to the mounting portion 115, thereby slidably connecting the push rod 122 to the housing 110.

[0078] In addition, one end of the push rod 122 close to the second opening 1214 may be located in the through hole 1211 , or may extend out of the second opening 1214 of the valve body 121 , depending on the type of the flexible sealing member 124 .

[0079] In some embodiments, Figure 6 As shown, the valve core 123 can be located at the side of the valve body 121 away from the flexible seal 124; the valve core 123 abuts or separates from the side surface of the valve body 121 away from the flexible seal 124 to seal or open the outlet 1213 of the valve body 121. Specifically, when the push rod 122 slides relative to the valve body 121 or the housing 110 along the direction from the second opening 1214 of the valve body 121 to the outlet 1213, the valve core 123 can be driven to move in the same direction to a position separated from the side surface of the valve body 121 away from the flexible seal 124 to open the outlet 1213 of the valve body 121; when the push rod 122 slides relative to the valve body 121 or the housing 110 along the direction from the outlet 1213 of the valve body 121 to the second opening 1214, the valve core 123 can be driven to move in the same direction to a position abutting against the side surface of the valve body 121 away from the flexible seal 124 to close the outlet 1213 of the valve body 121.

[0080] The first control valve 120 may further include an elastic member 125 connected to the valve body 121 or the housing 110, and the elastic member 125 may be connected to the push rod 122 or the valve core 123, so that the valve core 123 abuts against the surface of the side of the valve body 121 away from the flexible seal 124. The elastic member 125 applies elastic force to the valve core 123, so that the valve core 123 can be stably maintained at the position of closing the outlet 1213 of the valve body 121. When the outlet 1213 of the valve body 121 needs to be opened, the push rod 122 is applied with a thrust force in the direction from the second opening 1214 of the valve body 121 to the outlet 1213 through an external driving mechanism, which is more convenient to operate.

[0081] Specifically, the elastic member 125 can be sleeved on the push rod 122, and the elastic member 125 is located between the valve core 123 and the mounting portion 115, one end of the elastic member 125 abuts against the mounting portion 115, and the other end of the elastic member 125 abuts against the valve core 123, so as to apply an elastic force to the valve core 123 in the direction from the outlet 1213 of the valve body 121 to the second opening 1214. The elastic member 125 can be a spring, rubber, etc., which is not limited here.

[0082] In other embodiments, the first control valve 120 can be a one-way valve, and the inlet 1212 of the first control valve 120 is connected to the first communication port 1121, and the outlet 1213 of the first control valve 120 is connected to the buffer chamber 113. Therefore, when the water vapor collection device 100 absorbs air containing surgical smoke, the air in the liquid collection chamber 111 can be transmitted to the buffer chamber 113 through the first control valve 120, and when the water vapor collection device 100 stops absorbing air containing surgical smoke, the first control valve 120 can close the first communication port 1121 and the buffer chamber 113 to prevent the liquid in the liquid collection chamber 111 from overflowing from the first communication port 1121 to the buffer chamber 113.

[0083] In some embodiments, Figure 2 and Figure 3 As shown, the housing 110 may include an air inlet channel 116, one end of which is connected to the air inlet port 1101, and the other end of the air inlet channel 116 has a first opening 1161 connected to the liquid collecting chamber 111. When the water vapor collecting device 100 absorbs air containing surgical smoke, the air enters the air inlet channel 116 from the air inlet port 1101 and is discharged from the first opening 1161 into the liquid collecting chamber 111.

[0084] Among them, in the height direction Z of the water vapor collection device 100, the height of the air inlet 1101 is greater than the height of the first opening 1161. By setting the air inlet passage 116 and making the height of the air inlet 1101 greater than the height of the first opening 1161, the flow distance of the liquid from the liquid collection chamber 111 flowing back to the air inlet 1101 can be extended, which is beneficial to reducing the risk of the liquid in the liquid collection chamber 111 flowing back to the air inlet 1101 when the water vapor collection device 100 shakes. At the same time, after the water vapor in the air containing surgical smoke in the air inlet passage 116 sinks into the air inlet passage 116 under the action of gravity, it can flow into the liquid collection chamber 111 along the direction from the air inlet 1101 to the first opening 1161, and will not flow back to the air inlet 1101.

[0085] In some embodiments, in the height direction Z of the water vapor collection device 100, the height of the lowest point of the first opening 1161 of the air inlet passage 116 in the height direction Z can be made greater than the rated liquid level height in the liquid collection chamber 111, so as to reduce the risk of the liquid in the liquid collection chamber 111 flowing back into the air inlet passage 116.

[0086] In some embodiments, the air inlet passage 116 can be located at the top of the liquid collection chamber 111, so that the height of the lowest point of the first opening 1161 of the air inlet passage 116 in the height direction Z is greater than the rated liquid level height in the liquid collection chamber 111.

[0087] In some embodiments, the air inlet passage 116 can have a slope relative to the bottom surface of the liquid collection chamber 111, so that in the height direction Z of the water vapor collection device 100, the height of the air inlet 1101 is greater than the height of the first opening 1161. Specifically, in the direction from the air inlet 1101 to the first opening 1161, the air inlet passage 116 slopes downward, so that the air inlet passage 116 has a slope relative to the bottom surface of the liquid collection chamber 111, and the height of the air inlet 1101 is greater than the height of the first opening 1161.

[0088] Among them, the inclination angle of the air inlet passage 116 can be greater than or equal to 1° so that there is a sufficient height difference between the air inlet 1101 and the first opening 1161 of the air inlet passage 116. The inclination angle of the air inlet passage 116 can be 5°, 10°, 20°, 30°, 45°, 60°, 90°, etc., and there is no limitation here.

[0089] In some embodiments, as Figure 3 shown, the first opening 1161 of the air inlet passage 116 can be relatively spaced apart from the inner side surface 1110 of the liquid collection chamber 111 to form a space 1171 between the first opening 1161 of the air inlet passage 116 and the inner side surface 1110 of the liquid collection chamber 111, thereby reducing the resistance to air and enabling air to flow from the air inlet passage 116 to the liquid collection chamber 111 faster.

[0090] Specifically, as Figure 3 shown, the inner side surface 1110 of the liquid collecting cavity 111 may include a first side surface 1111 and a second side surface 1112 that are relatively spaced apart. The liquid collecting cavity 111 is located between the first side surface 1111 and the second side surface 1112. The air inlet channel 116 is located at the top of the liquid collecting cavity 111 and extends along the distribution direction of the first side surface 1111 and the second side surface 1112. The first opening 1161 of the air inlet channel 116 is spaced from the first side surface 1111, so that a space 1171 is formed between the first opening 1161 of the air inlet channel 116 and the first side surface 1111 of the liquid collecting cavity 111. The ratio of the length of the air inlet channel 116 to the distance between the first side surface 1111 and the second side surface 1112 is greater than or equal to 0.5, so as to ensure the length of the air inlet channel 116 and effectively prevent the liquid in the liquid collecting cavity 111 from flowing back to the air inlet 1101.

[0091] In some embodiments, as Figure 2 and Figure 3 shown, the housing 110 may further include a baffle 117 provided on the inner side surface 1110. One side plate surface of the baffle 117 is relatively spaced from the bottom surface of the liquid collecting cavity 111. In the height direction Z of the water vapor collecting device 100, the height of the baffle 117 is greater than the rated liquid level height in the liquid collecting cavity 111. Wherein, a space 1171 is formed between the first opening 1161 of the air inlet channel 116 and the inner side surface 1110, and the baffle 117 is located below the space 1171. Thus, the liquid in the liquid collecting cavity 111 can be blocked by the baffle 117, thereby further reducing the risk of the liquid in the liquid collecting cavity 111 flowing back into the air inlet channel 116.

[0092] Specifically, the first side surface 1111 and the second side surface 1112 are distributed along the second direction Y. One side edge of the baffle 117 is connected to the first side surface 1111, and the other side edge of the baffle 117 is connected to the bottom side edge of the first opening 1161, so as to further improve the blocking effect of the baffle 117 on the liquid in the liquid collecting cavity 111. A sealing plate 118 is provided on one side of the space 1171 above the baffle 117 along the first direction X. The plate surface of the sealing plate 118 is perpendicular to the first direction X, and a through hole 1181 is formed in the sealing plate 118. The space 1171 is communicated with the liquid collecting cavity 111 through the through hole 1181.

[0093] In other embodiments, as Figure 7 and Figure 8As shown, the water vapor collection device 100 may further include a second control valve 130 connected to the housing 110. The second control valve 130 is used to control the opening or closing of the air inlet 1101. Thus, when the water vapor collection device 100 absorbs the air containing surgical smoke, the second control valve 130 can control the air inlet 1101 to open, so that the air containing surgical smoke can be inhaled into the liquid collection chamber 111 through the air inlet 1101. When the water vapor collection device 100 does not absorb the air containing surgical smoke, the second control valve 130 can control the air inlet 1101 to close, so as to prevent the liquid in the liquid collection chamber 111 from leaking out through the air inlet 1101.

[0094] Among them, the second control valve 130 may be a one-way valve. Then, the second control valve 130 can automatically open the air inlet 1101 when the water vapor collection device 100 absorbs the air containing surgical smoke, and automatically close the air inlet 1101 when the water vapor collection device 100 does not absorb the air containing surgical smoke, which is very convenient to operate.

[0095] Specifically, the second control valve 130 includes a cover plate 131 movably connected to the housing 110. The cover plate 131 is located in the liquid collection chamber 111 and can move relative to the housing 110 between an open position and a closed position. When the cover plate 131 is in the closed position, it abuts against the inner side surface 1110 of the liquid collection chamber 111 and covers the air inlet 1101. When the cover plate 131 is in the open position, it separates from the inner side surface 1110 to open the air inlet 1101.
