Description

Technical Field

[0001] This disclosure relates to the technical field of safety protection, and in particular to a safety protection system for the testing process of an aircraft under test conditions. Background Technology

[0002] Throughout the entire production cycle of aircraft design, pre-research, and mass production, quality control at key stages is crucial for ensuring product safety and reliability. During the development phase, quality inspection often uses a no-fired joint training product as an equivalent of the final product to conduct preliminary tests on aircraft functions and environmental conditions. Environmental testing of the joint training product primarily involves collaborative efforts from four teams: aircraft loading, test bench control, test data monitoring, and aircraft condition testing. These tests focus on the aircraft's three-axis impact, vibration, and centrifugal mechanical properties. Such personnel and equipment-intensive conditions often result in high noise levels, poor layout, and a chaotic environment. High noise levels can easily cause tinnitus or even hearing loss among workers, seriously impacting their health. A chaotic environment and poor layout leading to high dust levels can cause contaminants to easily accumulate on the surface of aviation connectors. Untimely removal of contaminants can lead to frequent testing problems; metallic contaminants can even cause short circuits and burn out the mainboard, damaging the aviation connectors.

[0003] Therefore, it is necessary to propose a safety protection system for the testing process of aircraft test conditions in order to at least partially solve the problems existing in the prior art. Summary of the Invention

[0028] Specifically, when the first plate is pressed against the air intake, the return spring is compressed, and the flow guide and the first plate move towards the air intake, while the fixing member is in a ready-to-connect state; when the liquid-absorbing wiper is placed on the flow guide and the flow guide hole corresponds to the porous structure, the liquid-absorbing wiper is connected to the fixing member; when the pressure on the first plate is released, the return spring resets, and the flow guide and the first plate are pressed against the air intake and moved away from the air intake, while the fixing member is in a fixed state, and the liquid-absorbing wiper is fixedly connected to the opening of the first connecting frame.

[0029] In one feasible implementation, the wiping part further includes:

[0030] A buffer layer is provided at the end of the liquid-absorbing wiper that is away from the air intake.

[0031] In one feasible implementation, the humidification unit includes:

[0046] Compared to existing technologies, this disclosure offers at least the following advantages: The aircraft test condition testing process safety protection system provided in this disclosure includes a housing, a wiping section, a humidifying section, a fan, a positioning section, and a noise-filtering communication section. The housing has an internal placement cavity. The wiping section is connected to the housing and located on its side. It wipes the surface of the aviation connector to be cleaned to remove contaminants. Furthermore, the wiping section has a porous structure that connects to the placement cavity. The humidifying section covers the wiping section, allowing cleaning fluid to be supplied before wiping the surface. After humidification, the humidifying section is removed, making it easier to clean contaminants with the cleaning fluid. The fan is fixedly installed in the placement cavity via the positioning section. The fan's intake faces the wiping section, generating negative pressure airflow. The positioning section has a discharge structure, and the fan's exhaust port connects to the discharge structure. This design allows for efficient cleaning of the aviation connector's surface. While the cleaning fluid-soaked wiping unit removes dirt, a fan generates negative pressure to draw the dirt into the housing, from where it is discharged through a drainage structure. This avoids the blockage caused by simply wiping and pushing dirt into the connector's slots, as is common in other technologies. It also eliminates the need for alternating suction and wiping operations. Furthermore, the integrated humidification unit eliminates the need to spray cleaning fluid onto the surface while wiping, simplifying operation, improving cleaning efficiency, and enhancing the safety of the aviation connector. The safety protection system also integrates a noise-filtering communication unit, specifically located on the side of the housing. This unit includes an earpiece and a noise-filtering transmission unit. The noise-filtering transmission unit receives and filters ambient audio data, retaining only the low-frequency human voice data, which is then transmitted to the earpiece. This facilitates communication for on-site personnel, ensuring normal communication while reducing interference from environmental noise and its impact on staff's well-being, thus minimizing noise pollution and protecting their safety.

Detailed Implementation

[0068] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are merely for describing exemplary embodiments of the invention. However, the invention can be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0069] like Figures 1 to 18 As shown, according to an embodiment of this disclosure, a safety protection system 100 for aircraft test conditions is proposed, comprising: a housing 110, the interior of which is formed a placement cavity; a wiping part 120, connected to the housing 110 and located on the side of the housing 110, the wiping part 120 being used to wipe the surface of an aviation connector to be cleaned, the wiping part 120 being provided with a porous structure 1211, the wiping part 120 being connected to the placement cavity through the porous structure 1211; a humidifying part 130, covering the wiping part 120, for providing cleaning fluid to the wiping part 120; and a fan 140, fixedly installed in the placement cavity through a positioning part 160, the fan 140 being used to draw... The air vent 141 faces the wiping part 120. The fan 140 is used to generate negative pressure airflow to draw dirt from the surface of the aviation connector to be cleaned into the fan 140. The positioning part 160 is provided with a discharge structure. The exhaust port of the fan 140 is connected to the discharge structure, which is used to discharge the dirt drawn into the fan 140. The noise-filtering communication part 150 is provided on the side of the housing 110. The noise-filtering communication part 150 includes an earpiece 152 and a noise-filtering transmission unit. The noise-filtering transmission unit is used to receive and filter audio data to retain the low-frequency human voice data in the audio data and send the low-frequency human voice data to the earpiece 152.

[0070] It is understood that the aircraft test condition testing process safety protection system 100 provided in this embodiment includes a housing 110, a wiping section 120, a humidifying section 130, a fan 140, a positioning section 160, and a noise-filtering communication section 150. The housing 110 has a placement cavity inside. The wiping section 120 is connected to the housing 110 and located on the side of the housing 110. The wiping section 120 is used to wipe the surface of the aviation connector to be cleaned to remove dirt. Furthermore, the wiping section 120 has a porous structure 1211, which connects the wiping section 120 to the placement cavity. The humidifying section 130 covers the wiping section 120. Before wiping the surface to be cleaned, cleaning fluid can be supplied to the wiping section 120 through the humidifying section 130. After humidification, the humidifying section 130 is removed, and the cleaning fluid makes it easier to clean dirt. The fan 140 is fixedly installed in the placement cavity via the positioning part 160. The air intake 141 of the fan 140 faces the wiping part 120. The fan 140 can generate negative pressure airflow, and the positioning part 160 is provided with a discharge structure. The exhaust port of the fan 140 is connected to the discharge structure. With this configuration, when wiping the surface of the aviation connector to be cleaned, while the wiping part 120, which is soaked in cleaning fluid, wipes away the dirt, the negative pressure generated by the fan 140 draws the dirt into the housing 110 and discharges it through the discharge structure. This avoids the blockage caused by pushing dirt into the slots of the aviation connector during the wiping action alone, as is the case in related technologies. It also eliminates the need to alternate between suction and wiping operations. Furthermore, the integrated humidification part 130 eliminates the need to spray cleaning fluid onto the surface to be cleaned while wiping, making operation convenient, improving cleaning efficiency, and enhancing the safety protection of the aviation connector. The safety protection system integrates a noise-filtering communication unit 150. Specifically, the noise-filtering communication unit 150 is located on the side of the housing 110 and includes an earpiece 152 and a noise-filtering transmission unit. The noise-filtering transmission unit can receive and filter audio data from the surrounding environment, retaining low-frequency human voice data and transmitting it to the earpiece 152. This facilitates communication among on-site personnel, ensuring normal communication while reducing interference from environmental noise and its impact on the physical and mental well-being of staff, thus reducing noise pollution and protecting their safety. For example, a cleaning solution, such as alcohol, can be selected based on actual on-site needs.

[0071] For example, such as Figure 3 As shown, a mounting groove 190 is provided on the side of the positioning part 160. The noise-filtering communication part 150 may also be provided with a placement box 153 and a cover plate 154. The placement box 153 is installed in the mounting groove 190, and the cover plate 154 covers the placement box 153. An earphone 152 can be placed inside the placement box 153. Figure 5As shown, the noise-filtering transmission unit can be an interconnected noise-filtering motherboard 151, which is installed on the back of the placement box 153. The interconnected noise-filtering motherboard 151 integrates a radio module, a noise-filtering module, a multi-device wireless data transmission module, and a motherboard earpiece 152 data transmission module. With this configuration, communication is conducted via the radio module. The noise-filtering module selects only the low-frequency range of human voice data from the mixed signal-to-noise data. The noise-filtered low-frequency human voice data is then transmitted to other interconnected noise-filtering motherboards 151 via the multi-device wireless data transmission module and received. Finally, the low-frequency human voice data is transmitted from the interconnected noise-filtering motherboard 151 to the earpiece 152 via the motherboard earpiece 152 data transmission module, allowing the staff wearing the earpiece 152 to receive the data. This reduces the ambient noise heard by staff while enabling clear conversation, reduces interference from environmental noise on communication signals and its impact on staff's physical and mental well-being, reduces noise pollution, and provides safety protection for staff.

[0072] For example, such as Figure 18 As shown, the earbud 152 includes a body 1521 and a communication component. The body 1521 is a compressible structure, comprising a speaker mounting section 1522, a middle section 1523, and a tail mounting section 1524. The speaker mounting section 1522 is located near the front end of the body 1521, and the size of the middle section 1523 is smaller than the inner diameter of the speaker mounting section 1522. The outer diameter of the front end of the body 1521 is smaller than the outer diameter of the tail end. The communication component includes an electroacoustic transducer 1525, a wire 1526, a receiver plate 1527, and a power supply battery 1528. The electroacoustic transducer 1525 is mounted within the speaker mounting section 1522, the wire 1526 is housed within a rigid tube in the middle section 1523, and both the receiver plate 1527 and the power supply battery 1528 are located within the tail mounting section 1524. The receiver board 1527 is electrically connected to the electroacoustic transducer 1525 via wire 1526, and the earpiece 152 is powered by a communication battery. This allows the receiver board 1527 to convert the low-frequency audio data signal of human voice received into a sound wave signal, enabling the worker wearing the earpiece 152 to hear the human voice clearly.

[0073] In some examples, such as Figures 1 to 5As shown, the aforementioned housing 110 includes: a first encapsulation portion 111, which includes a first connecting frame 1111 and a first cover plate 1112, the first cover plate 1112 covering the first connecting frame 1111, and the aforementioned placement cavity being formed inside the first encapsulation portion 111; and a second encapsulation portion 112, sleeved on the first encapsulation portion 111, which includes a second connecting frame 1121 and a second cover plate 1122, the second cover plate 1122 covering the second connecting frame 1121; wherein... Both the first connecting frame 1111 and the second connecting frame 1121 have openings on their periphery, and the opening of the first connecting frame 1111 is connected to the opening of the second connecting frame 1121. The wiping part 120 is connected to the opening of the first connecting frame 1111 by a fastener. The first encapsulation part 111 has a first discharge port 1114, and the second encapsulation part 112 has a second discharge port 1124. The first discharge port 1114, the second discharge port 1124 and the discharge structure are connected.

[0074] It is understood that the housing 110 is provided with a first encapsulation part 111 and a second encapsulation part 112. The first encapsulation part 111 is provided with a first connecting frame 1111 and a first cover plate 1112, with the first cover plate 1112 covering the first connecting frame 1111 to form a placement cavity inside the first encapsulation part 111. The second encapsulation part 112 is provided with a second connecting frame 1121 and a second cover plate 1122, with the second cover plate 1122 covering the second connecting frame 1121 so that the second encapsulation part 112 is fitted onto the first encapsulation part 111. The first encapsulation part 111 and the second encapsulation part 112 provide two layers of protection, improving reliability. Both the first connecting frame 1111 and the second connecting frame 1121 have openings on their peripheries, and the opening of the first connecting frame 1111 is connected to the opening of the second connecting frame 1121. The wiping part 120 is connected to the opening of the first connecting frame 1111 by a fastener and can extend out of the opening of the second connecting frame 1121 to wipe the surface to be cleaned. The humidifying part 130 can cover the opening corresponding to the wiping part 120. A first discharge port 1114 is provided at the corresponding position of the first cover plate 1112 and the first connecting frame 1111, and a second discharge port 1124 is provided at the corresponding position of the second cover plate 1122 and the second connecting frame 1121. The first discharge port 1114, the second discharge port 1124 and the discharge structure are connected, so that after the fan 140 extracts the cleaned dirt, the dirt can be discharged sequentially through the discharge structure, the first discharge port 1114 and the second discharge port 1124.

[0075] In some examples, such as Figure 4 As shown, a mounting member 1123 is provided on the outer side wall of the second encapsulation part 112.

[0076] It is understandable that the outer wall of the second encapsulation part 112 may be provided with a hanging part 1123, such as a hook, to facilitate hanging and easy carrying by staff.

[0077] In some examples, such as Figures 1 to 10 As shown, the wiping section 120 includes: a liquid-absorbing wiping plate 121 for absorbing the cleaning liquid provided by the humidifying section 130, the liquid-absorbing wiping plate 121 having the porous structure 1211, the liquid-absorbing wiping plate 121 being fixedly connected to the opening of the first connecting frame 1111 by the fixing member, and the liquid-absorbing wiping plate 121 for wiping the surface of the aviation connector to be cleaned; a flow guide shroud 122 disposed between the liquid-absorbing wiping plate 121 and the air intake 141; and a first plate 123 located between the flow guide shroud 122 and the liquid-absorbing wiping plate 121, the first plate 123 having a plurality of flow guide holes 1231, the flow guide holes 1231, the air intake 141 and the porous structure 1211 being connected.

[0078] It is understood that the wiping section 120 may be provided with a liquid-absorbing wiping plate 121, a flow guide shroud 122, and a first plate 123. The humidifying section 130 is used to cover the liquid-absorbing wiping plate 121. The liquid-absorbing wiping plate 121 may be made of a material with good cleaning liquid performance and high hardness to absorb the cleaning liquid provided by the humidifying section 130. The wiping plate has a porous structure 1211, and the liquid-absorbing wiping plate 121 can be fixedly connected to the opening of the first connecting frame 1111 by a fastener. A flow guide shroud 122 is positioned between the liquid-absorbing wiping plate 121 and the air intake 141 of the fan 140 to guide the negative pressure airflow of the fan 140 through the porous structure 1211 of the liquid-absorbing wiping plate 121 to act on the surface of the aviation connector to be cleaned. A first plate 123 is located between the flow guide shroud 122 and the liquid-absorbing wiping plate 121, and the first plate 123 has multiple flow guide holes 1231, which correspond to the holes of the porous structure 1211. With this configuration, when wiping, after starting the fan 140, the liquid-absorbing wiping plate 121 can be moved close to the surface to be cleaned to suck away the dirt with weak adhesion to the surface through the negative pressure airflow. The suction wiper 121 is then pressed against the surface to be cleaned. The first plate 123 provides support to the suction wiper 121, ensuring that the cleaning fluid on the suction wiper 121 effectively acts on the strongly adhering dirt. Sufficient wiping force is also provided to the suction wiper 121 to separate the strongly adhering dirt from the surface of the aviation connector. The dirt is then drawn into the fan 140 by negative pressure airflow and discharged through the exhaust structure. This entire operation avoids the blockage that occurs in related technologies where wiping alone pushes dirt into the slots of the aviation connector. It also eliminates the need for alternating suction and wiping operations, making operation convenient, improving cleaning efficiency, and enhancing the safety protection of the aviation connector.

[0079] In some examples, such as Figures 1 to 10 As shown, the wiping part 120 further includes: a second plate 124 disposed between the air guide shroud 122 and the air intake 141, wherein a first connecting hole 1241 is formed in the middle of the second plate 124, the first connecting hole 1241 is connected to the air guide hole 1231, and a mounting hole 1242 is formed on the periphery of the first connecting hole 1241; a return spring 125, one end of the return spring 125 is mounted in the mounting hole 1242, and the other end faces the air intake 141; A third plate 126 is disposed between the second plate 124 and the air intake 141. A second connecting hole 1261 is formed in the middle of the third plate 126, connecting to the guide hole 1231. A through hole 1262 is formed on the periphery of the second connecting hole 1261, through which the return spring 125 passes. A fourth plate 127 is disposed between the third plate 126 and the air intake 141. A second connecting hole 1261 is formed in the middle of the fourth plate 127. A third connecting hole 1271 is provided, which connects to the guide hole 1231. The other end of the return spring 125 is used to press against the fourth plate 127. When the first plate 123 is pressed against the air intake 141, the return spring 125 is compressed, and the guide cover 122 and the first plate 123 move towards the air intake 141, and the fixing member is in a ready-to-connect state. The liquid-absorbing wipe 121 is then placed on top of the... When the aforementioned flow guide shroud 122 and the aforementioned flow guide hole 1231 correspond to the aforementioned porous structure 1211, the aforementioned liquid suction wiper 121 is connected to the aforementioned fixing member; when the top pressure on the aforementioned first plate 123 is released, the aforementioned return spring 125 returns to its original position, pressing the aforementioned flow guide shroud 122 and the aforementioned first plate 123 to move away from the aforementioned air intake 141, the aforementioned fixing member is in a fixed state, and the aforementioned liquid suction wiper 121 is fixedly connected to the aforementioned opening of the aforementioned first connecting frame 1111.

[0080] It is understood that the wiping section 120 may also be provided with a second plate 124, a return spring 125, a third plate 126, and a fourth plate 127. The second plate 124 is disposed between the air guide shroud 122 and the air intake 141, and a first connecting hole 1241 is formed in the center of the second plate 124, connecting to the air guide hole 1231. Four mounting holes 1242 are formed around the first connecting hole 1241, evenly distributed around it. One end of the return spring 125 is mounted in the mounting hole 1242, and the other end faces the air intake 141. The third plate 126 is disposed between the second plate 124 and the air inlet 141. A second connecting hole 1261 is formed in the middle of the third plate 126, which connects to the guide hole 1231. Four through holes 1262 are formed around the second connecting hole 1261, and the positions of the through holes 1262 and the mounting holes 1242 correspond to each other. The return spring 125 passes through the through holes 1262. The third plate 126 restricts the circumferential displacement of the return spring 125, thereby improving reliability. The fourth plate 127 is disposed between the third plate 126 and the air inlet 141. A third connecting hole 1271 is formed in the middle of the fourth plate 127, which connects to the guide hole 1231. The other end of the return spring 125 is used to press against the fourth plate 127. With this configuration, when the first plate 123 is pressed against the air intake 141, the return spring 125 is compressed, and the guide shroud 122 and the first plate 123 move towards the air intake 141, with the fixing member in a ready-to-connect state. When the liquid-absorbing wiper 121 is placed on the guide shroud 122 with the guide hole 1231 corresponding to the porous structure 1211, the liquid-absorbing wiper 121 is connected to the fixing member. When the pressure on the first plate 123 is released, the return spring 125 returns to its original position, and the guide shroud 122 and the first plate 123 move away from the air intake 141, with the fixing member in a fixed state, and the liquid-absorbing wiper 121 is fixedly connected to the opening of the first connecting frame 1111. This allows for quick assembly and disassembly of the liquid-absorbing wiper 121, making operation convenient.

[0081] For example, such as Figure 12 As shown, the fixing component can be a tightening flange 1113. When the first plate 123 is pressed against the air inlet 141, the return spring 125 is compressed, and the guide shroud 122 and the first plate 123 move towards the air inlet 141, creating a gap between the first plate 123 and the tightening flange 1113, which allows the edge of the liquid-absorbing wiper 121 to be inserted into the gap. When the pressure on the first plate 123 is released, the return spring 125 returns to its original position, and the guide shroud 122 and the first plate 123 move away from the air inlet 141, thereby securing the liquid-absorbing wiper 121 and completing the replacement.

[0082] In some examples, the wiping section 120 further includes a buffer layer disposed at one end of the liquid-absorbing wiping plate 121 away from the air intake 141.

[0083] It is understandable that the wiping section 120 may also be provided with a buffer layer, which may be a buffer surface layer, and is provided at the end of the liquid suction wiping plate 121 away from the air intake 141, so as to avoid the liquid suction wiping plate 121 and the surface to be cleaned from making excessive hard contact, thereby improving the protection of the surface to be cleaned.

[0084] In some examples, such as Figures 15 to 17 As shown, the humidification unit 130 includes: a cover 131, which is detachably covered on the liquid-absorbing wipe plate 121, and the cover 131 is used to store cleaning liquid; and an atomizing component 132, which is disposed at one end of the cover 131 facing the liquid-absorbing wipe plate 121, forming an atomizing area between the cover 131 and the liquid-absorbing wipe plate 121, and the atomizing component 132 is used to agitate the cleaning liquid stored in the cover 131 to generate atomized cleaning liquid and output it to the atomizing area.

[0085] It is understood that the humidification unit 130 may be provided with a cover 131 and an atomizing component 132. The cover 131 is detachably mounted on the liquid-absorbing wiping plate 121. The cover 131 can store cleaning fluid. The atomizing component 132 is located at the end of the cover 131 facing the liquid-absorbing wiping plate 121, and an atomizing area is formed between the cover 131 and the liquid-absorbing wiping plate 121. The atomizing component 132 can agitate the cleaning fluid stored in the cover 131 to generate atomized cleaning fluid, and output the atomized cleaning fluid to the atomizing area to humidify the liquid-absorbing wiping plate 121, ensuring uniform humidification. This combines negative pressure suction with cleaning fluid wiping, enabling simultaneous operation of both. This effectively solves the technical problem in related technologies where wiping alone can easily push dirt into the slots of the aviation connector, causing blockage. It also eliminates the need for alternating suction and wiping operations, making operation convenient, improving cleaning efficiency, and enhancing the safety protection of the aviation connector.

[0086] For example, such as Figure 15 As shown, the opening end face of the first connecting frame 1111 is provided with a slot 1115, and the end of the cover 131 facing the first connecting frame 1111 is provided with a snap-fit ​​extension edge 1314. The snap-fit ​​extension edge 1314 can snap into the slot 1115, and the snap-fit ​​extension edge 1314 is provided with a first metal contact 1315. Correspondingly, the side wall of the slot 1115 is provided with a second metal contact. When the cover 131 is installed in place, the first metal contact 1315 and the second metal contact are engaged. Figure 3 and Figure 4As shown, a first mounting groove 190170 and a first outer cover 171 are provided on the side of the positioning part 160. A control main board 172 is disposed in the first mounting groove 190170, and the first outer cover 171 is disposed on the first mounting groove 190170. An interactive button 173 electrically connected to the control main board 172 is provided on the outside of the first outer cover 171. The control main board 172 is electrically connected to the fan 140, and when the first metal contact 1315 and the second metal contact are mated, it is electrically connected to the atomizing component 132. A second mounting groove 190180 and a second outer cover 181 are provided on the other side of the positioning part 160. A battery box 182 is disposed in the second mounting groove 190180, and the second outer cover 181 is disposed on the second mounting groove 190180. Power is supplied to the control main board 172, the fan 140, and the atomizing component 132 by installing a battery into the battery box 182. Specifically, when the first metal contact 1315 and the second metal contact are connected, clicking the interaction button 173 controls the atomizing component 132 to operate via the control motherboard 172, thereby generating atomized cleaning fluid to humidify the liquid suction plate 121. Then, the humidifying part 130 is removed, and clicking the interaction button 173 starts the fan 140 to perform the cleaning operation.

[0087] In some examples, such as Figures 15 to 17 As shown, the cover 131 includes: a cover body 1311, the cover body 1311 having a storage cavity 1316 and an injection port 1317 inside, wherein the storage cavity 1316 is used to store cleaning fluid, and the injection port 1317 is used to inject cleaning fluid into the storage cavity 1316; a third cover plate 1312, which is disposed on the end of the cover body 1311 away from the liquid-absorbing wiping plate 121, and is used to seal the storage cavity 1316; and a sealing ring 1313, which is disposed between the cover body 1311 and the third cover plate 1312.

[0088] It is understood that the cover 131 may include a cover body 1311, a third cover plate 1312, and a sealing ring 1313. The cover body 1311 has an internal storage cavity 1316 and an injection port 1317, through which cleaning fluid is injected into the storage cavity 1316. The third cover plate 1312 is placed on the end of the cover body 1311 facing away from the absorbent wiping plate 121 to seal the storage cavity 1316. The sealing ring 1313 is positioned between the cover body 1311 and the third cover plate 1312 to ensure a tight seal and prevent cleaning fluid from leaking out of the storage cavity 1316.

[0089] In some examples, such as Figures 15 to 17As shown, the atomizing component 132 includes: a permeation layer 1321 disposed between the storage cavity 1316 and the third cover plate 1312; an atomizing plate 1322 disposed at one end of the cover 131 facing the liquid-absorbing wiping plate 121; and a drainage member 1323 disposed between the permeation layer 1321 and the atomizing plate 1322 for draining the cleaning liquid in the permeation layer 1321 to the atomizing plate 1322.

[0090] It is understood that the atomizing assembly 132 may be provided with a permeation layer 1321, an atomizing plate 1322, and a drainage element 1323. The permeation layer 1321 is disposed between the storage cavity 1316 and the third cover plate 1312 to allow the cleaning fluid in the storage cavity 1316 to permeate into the permeation layer 1321. The atomizing plate 1322 is disposed at the end of the cover 131 facing the liquid-absorbing wiping plate 121. The cleaning fluid in the permeation layer 1321 is guided to the atomizing plate 1322 by the drainage element 1323, and the atomizing plate 1322 agitates the cleaning fluid to generate atomized cleaning fluid.

[0091] In some examples, such as Figures 11 to 14 As shown, the positioning part 160 includes: a positioning member 161, which has a positioning arc surface for mounting the fan 140; the discharge structure includes a guide channel 162 and a third discharge port 163, the guide channel 162 being connected to the positioning member 161 and protruding toward the positioning arc surface, the opening direction of the guide channel 162 being consistent with the axial direction of the positioning arc surface, the third discharge port 163 being located on the side of the positioning part 160 away from the fan 140, and the third discharge port 163 being connected to the guide channel 162; and a baffle 164 being located at the opening of the guide channel 162, facing the positioning arc surface to reduce the size of the opening, and the baffle 164 being used to prevent the backflow of dirt in the guide channel 162.

[0092] It is understood that the positioning part 160 may be provided with a positioning element 161 and a baffle 164. The positioning element 161 has a positioning arc surface, the arc contour of which matches the outer contour of the fan 140, so as to fix the fan 140 by clamping the positioning arc surface. The discharge structure is provided with a guide channel 162 and a third discharge port 163. The guide channel 162 is connected to the positioning element 161 and protrudes towards the positioning arc surface. The opening direction of the guide channel 162 is consistent with the axial direction of the positioning arc surface. The third discharge port 163 is located on the side of the positioning part 160 away from the fan 140, and the third discharge port 163 connects to the guide channel 162 and the first discharge port 1114. This arrangement, as... Figure 11As shown, the negative pressure airflow generated by the fan 140 draws the dirt into the housing 110. Through the guiding effect of the guide shroud 122, the dirt flows from the opening of the guide groove 162 into the guide groove 162, and flows along the guiding direction of the guide groove 162 to the third discharge port 163. The dirt is then discharged into the external environment through the third discharge port 163, the first discharge port 1114, and the second discharge port 1124. Furthermore, a baffle 164 is provided at the opening of the guide channel 162. The baffle 164 is positioned towards the positioning arc surface to reduce the size of the opening. The contour of the end of the baffle 164 facing the positioning arc surface is formed with a slope so that the airflow can carry the dirt and guide it into the guide channel 162 along the slope. With this configuration, after the airflow carries the dirt into the guide channel 162, the airflow impacts the inner wall of the guide channel 162 and changes direction. It may carry the dirt back to the opening of the guide channel 162, affecting the discharge of dirt. By setting the baffle 164, the dirt can be effectively blocked from rushing out from the opening of the guide channel 162, so that the dirt falls back into the guide channel 162 and flows towards the third discharge port 163 under the drive of the airflow.

[0093] For example, the positioning member 161 can be disassembled into two parts, and the two parts of the positioning member 161 can be combined by a connector to form a complete positioning member 161 for positioning the fan 140. The connector can be a combination of snap-fit ​​and latch.
