Detailed Description

The technical solution of the present invention is clearly and completely explained below with reference to the accompanying drawings through the concrete implementation of the embodiments of the present invention.

Referring to fig. 1-7, the present invention relates to a cleaning device for air duct, which comprises a closed chamber 1, wherein the closed chamber 1 is provided with a water inlet 2 and a fixing hole 13, the inner ring of the fixing hole 13 is connected with the outer pipe wall of the air duct, and the fixing hole 13 communicates with the inner side and the outer side of the closed chamber 1.

The arrangement of the closed chamber 1 ensures the flushing intensity of the air conduit. When the cleaning liquid enters the closed chamber 1, only the fixed hole 13 of the closed chamber 1 is communicated with the outside in use, so that the cleaning liquid in the closed chamber 1 can be discharged only from the air conduit connected with the fixed hole 13. The total flow rate of water over the air duct is therefore the same as the flow rate of water at the water inlet 2, the greater the flushing effect on the air duct.

The air guide tube is a curved tapered tube so that the fixing hole 13 can fix the air guide tube as long as the diameter of the fixing hole 13 is not greater than the maximum diameter of the air guide tube.

The closed chamber 1 can also flush a plurality of air guide pipes at the same time. Since the air guide pipe is connected with the fixing hole 13, as long as the closed chamber 1 is provided with a plurality of fixing holes 13, the plurality of air guide pipes can be fixedly washed at the same time. If the number of the fixing holes 13 is excessive, plugs with the same size as the fixing holes 13 can be arranged to plug the fixing holes 13, so that water flow is only discharged from the air guide pipe, and the cleaning liquid can be fully utilized. In the absence of a matching plug, a towel may also be used to block the remaining securing holes 13.

For convenience of placement and removal, the air guide tube is connected to the fixing hole 13 in such a manner as to be directly inserted into the fixing hole 13, and thus the cleaning solution may still leak between the air guide tube and the fixing hole 13. In order to prevent the cleaning liquid from leaking outside and causing a mess to the external environment, a space for collecting waste water needs to be provided. The cleaning device further comprises a drain chamber 10, the fixing hole 13 communicates with the drain chamber 10, and one end of the air guide pipe is located in the drain chamber 10. Each of the fixing holes 13 communicates with the drain chamber 10, and either the waste water flowing from the air guide or the cleaning liquid between the air guide and the fixing hole 13 flows into the drain chamber 10. The drainage chamber 10 collects waste water, and can prevent leakage. After the wastewater is uniformly collected in the drainage chamber 10, the wastewater can be uniformly treated.

The air duct is fixedly connected with the fixing hole 13, but under the action of water flow, the air duct still swings, and the swing can cause the air duct to be separated from the fixing hole 13. A pipe clamp 18 is thus provided in the drain chamber 10, said pipe clamp 18 being used to secure a gas conduit. The clamp 18 is clamped to the outer wall of the air tube to prevent the air tube from swinging. A support rod 17 is arranged in the drainage chamber 10, the pipe clamp 18 is arranged on the top of the support rod 17, and the support rod 17 is used for increasing the height of the pipe clamp 18 so that the height of the pipe clamp 18 can correspond to the fixing hole 13. When the height of the pipe clamp 18 corresponds to the height of the fixing hole 13, the axis of the air guide pipe may be substantially parallel to the axis of the fixing hole 13, so that the outer side wall of the air guide pipe is more closely attached to the wall of the fixing hole 13. Therefore, less cleaning liquid leaks between the air guide pipe and the fixing hole 13, the waste of the cleaning liquid is reduced, and the utilization rate of the cleaning liquid is increased.

The strut 17 may be fixed to the bottom of the drain chamber 10 by welding or screwing. The support rod 17 may be fixedly connected at both ends to the side wall of the drain chamber 10, and a plurality of pipe clamps 18 are fixed to the support rod 17 in the axial direction of the support rod 17. The connection of the strut 17 to the pipe clamp 18 can be by welding or screwing.

In the embodiment shown in fig. 7, the collet 18 is in the shape of an open ring. The pipe clamp 18 is made of elastic plastic or metal, and clamps the air guide pipe by elasticity, thereby fixing the air guide pipe. The openings in the clamp 18 increase the range of deformation of the clamp 18 to facilitate the snapping in of the air tube.

Preferably, the cleaning device further comprises an ultrasonic generator 14, wherein the ultrasonic generator 14 is arranged on the closed chamber 1 and/or the drainage chamber 10. The ultrasonic generator 14 may be separately provided in a closed type; or separately provided on the drain chamber 10; or on both the closed chamber 1 and the drain chamber 10. The ultrasonic generator 14 is used for generating ultrasonic waves, and the ultrasonic waves are transmitted into the closed chamber 1 and the drainage chamber 10 to form a cavitation effect in the cleaning liquid in the closed chamber 1 and the drainage chamber 10. The substance such as sputum and the like adhered on the air conduit is separated from the air conduit by utilizing the cavitation effect. After substances such as sputum are separated from the air duct, the substances such as the sputum can float in the cleaning fluid, and the sputum can be washed away when the cleaning fluid is washed again.

The ultrasonic generator 14 is connected with a controller 15, and the controller 15 controls the work of the ultrasonic generator 14. The controller 15 is a PLC or a single chip microcomputer, and the controller 15 is electrically connected with the ultrasonic pen generator. And the ultrasonic generator 14 purchased at the time of purchase is also typically provided with a controller 15.

Preferably, there are two ultrasonic generators 14, and two ultrasonic generators 14 are respectively fixed on the outer side surfaces of the bottom of the closed chamber 1 and the drain chamber 10.

The cavitation effect means that high-frequency oscillation waves generated by the ultrasonic generator 14 are transmitted into the cleaning liquid to enable the liquid to flow to generate a large amount of bubbles, the bubbles cover the surface of the cleaning object and surround the cleaning object layer by layer, and finally, after a certain air pressure degree is reached, the bubbles are exploded, so that stains such as sputum and the like on the surface of the air conduit are gradually fallen off.

When the ultrasonic generator 14 is used, the water inlet 2 stops feeding the cleaning liquid into the closed chamber 1 and keeps the cleaning liquid submerging the air duct, so that the cleaning liquid acted by the ultrasonic generator 14 can act on the air duct.

More and more washing liquid is collected in the drain chamber 10, since the inlet 2 will continue to feed washing liquid into the closed chamber 1 during the flushing process. Therefore, an overflow hole 9 is provided in the drain chamber 10, and the height of the overflow hole 9 is higher than that of the air duct. The height of the overflow hole 9 is higher than that of the air conduit, so that the liquid level of the cleaning liquid can completely cover the air conduit when the ultrasonic generator 14 works. The overflow hole 9 can be externally connected with an overflow pipe, and when the height of the wastewater in the drainage chamber 10 exceeds the overflow hole 9, the wastewater enters the overflow pipe from the overflow hole 9 and is discharged.

Preferably, the closed chamber 1 and the drainage chamber 10 are located in the same box, the closed chamber 1 and the drainage chamber 10 are separated by a partition plate 8, and the fixing hole 13 is located on the partition plate 8. That is, after the partition plate 8 is provided in the tank body, the partition plate 8 divides the internal space of the tank body into two parts, one part is the closed chamber 1, and the other part is the drain chamber 10. The fixing hole 13 is provided on the partition plate 8, and when the cleaning liquid in the sealed chamber 1 flows out from the fixing hole 13, it is inevitably dropped into the drain chamber 10.

To prevent the cleaning liquid from leaking from the gap between the partition plate 8 and the tank, the partition plate 8 and the tank may be of an integrally formed stainless steel structure. Or a sealing layer is sleeved on the edge of the partition plate 8, so that the partition plate 8 is connected with the box body through the sealing layer. When the partition plate 8 and the box body are not integrally formed, a fixing structure for fixing the partition plate 8 is required to be arranged on the inner side wall of the box body. The fixing structure is a fixing groove, the inner side wall of the impurity box body is provided with the fixing groove, the partition plate 8 is inserted into the fixing groove, and the sealing layer sleeved on the edge of the partition plate 8 abuts against the groove bottom and the side wall of the fixing groove. This connection structure also allows the hermetic chamber 1 and the drain chamber 10 to be hermetically isolated.

The cleaning of the air conduit requires the use of a dedicated cleaning fluid, which is therefore conveyed into the closed chamber 1 by means of a water pumping device. The water inlet 2 is connected with a water pump 16, and water is supplied into the closed chamber 1 through the water pump 16. When the water pump 16 is selected, the high-pressure water pump 16 with high pressure is preferably selected, and the high-pressure water pump 16 is selected to directly flush the air duct by using the high pressure of the water pump 16 itself. Because the closed chamber 1 is only communicated with the outside through the fixed hole 13, the water pump 16 with low pressure, low flow and large caliber can be selected, the cleaning liquid in the closed chamber 1 cannot be discharged from other positions, the flow in the air guide pipe is forced to be increased, the flow speed of the cleaning liquid in the air guide pipe is accelerated, and the cleaning effect of the cleaning liquid on the inner side wall of the air guide pipe can be ensured.

Preferably, the height of the water inlet 2 is equal to the height of the fixing hole 13, so that water flow in the water inlet 2 can directly flow to the fixing hole 13, and the impact force generated when the water flow enters the closed chamber 1 is fully utilized to enhance the flushing of the air conduit.

The sealed chamber 1 and the drainage chamber 10 are both provided with drainage holes 3, and the drainage holes 3 are both connected with drainage pipes. After the flushing work of the air guide pipe is completed, the cleaning liquid or the waste water in the closed chamber 1 and the drain chamber 10 needs to be discharged. Since the cleaning liquid in the sealed chamber 1 is in contact with the air guide pipe at this time, the cleaning liquid in the sealed chamber 1 is discharged together with the waste water because the cleaning liquid is not recovered. Therefore, the two drain pipes and the overflow pipe are converged into one drain main pipe, so that the water flows in the overflow pipe and the drain pipes finally flow out of the drain main pipe.

Preferably, the water inlet 2 is connected with the water pump 16 through a water inlet pipe, the overflow pipe, the drain pipe and the main drain pipe are hoses, and when the drain pipe, the overflow pipe and the main drain pipe are connected, water pipe joints are used for connection.

Before starting the flushing, the gas conduit needs to be placed on the fixing hole 13 in the closed chamber 1; after the flushing has been completed, the air duct needs to be removed from the fixing hole 13 of the closed chamber 1. The closed chamber 1 needs to be openable. An opening is formed in the closed chamber 1, an openable cover 11 is arranged on the opening, and a sealing structure 12 is arranged between the cover 11 and the opening. The sealing structure 12 is a sealing ring or a sealing strip. The sealing structure 12 may be disposed at the bottom of the cover 11, and when the cover 11 is connected to the opening, the sealing structure 12 is located at the connection position of the cover 11 and the opening, so as to seal the cover 11 and the opening. Similarly, the sealing structure 12 may be disposed at the connection point of the opening and the cover 11.

To maintain a seal between the lid 11 and the opening, it is also desirable that the lid 11 be able to tightly engage the opening so that the lid 11 can compress the seal 12. A connection is thus provided between the lid 11 and the opening.

Preferably, said connection means comprise a hinge by which one side of the lid 11 is connected to the closed chamber 1 and a latch by which the other side opposite to the hinge is connected to the closed chamber 1. The tightness of the closed chamber 1 can be ensured only by ensuring that the sealing structure 12 is in a compressed state when the cover 11 is connected with the closed chamber 1 by the latch.

Preferably, the connecting element may also be a hinge and a buckle, one side of the lid 11 is connected to the closed chamber 1 through the hinge, and the other side opposite to the hinge is fixed to the closed chamber 1 by the buckle, and the buckle is arranged on the closed chamber 1 and used for fixing the lid 11. The buckle is in a structure of a lunch box buckle. Similarly, the sealing of the sealed chamber 1 can be ensured only by ensuring that the sealing structure 12 is in a compressed state when the lid 11 is fixed.

Preferably, the cover 11 can simultaneously shield the top of the drainage chamber 10, the part of the cover 11 above the drainage chamber 10 is made of transparent material, and when the cover 11 covers the closed chamber 1 and the drainage chamber 10, the conditions in the drainage chamber 10 and the closed chamber 1 can be observed through the transparent cover 11, so as to judge the operation of the water pump 16 and the ultrasonic generator 14. The cover 11 covers the drain chamber 10 together with the drain chamber 10, thereby preventing the waste water in the drain chamber 10 from splashing out of the drain chamber 10.

If the cover 11 is opaque, the operation time of the water pump 16 and the ultrasonic generator 14 should be determined through experiments or experience. Opaque covers 11 have the disadvantage of imprecise control compared to covers 11 of transparent material.

Preferably, the bottom of the box body is provided with a bracket which comprises a support leg 7 and a plurality of layers of partition plates 8. The uppermost partition plate 8 is the baffle plate 4, and the baffle plate 4 is located below the ultrasonic generator 14. The lower side of the sound insulation plate 4 is provided with a water stop plate 5, and a controller 15 of the ultrasonic generator 14 is fixed on the water stop plate 5, so that the controller 15 is positioned between the sound insulation plate 4 and the water stop plate 5. And a pump mounting plate 6 is arranged on the lower side of the water stop plate 5, and the pump mounting plate 6 is used for mounting a water pump 16. The water pump 16 is located between the water stop sheet 5 and the pump mounting plate 6.

The acoustic baffle 4 is used for isolating the ultrasonic waves generated by the ultrasonic generator 14, and the influence of the ultrasonic waves on the controller and the water pump is avoided.

The water-stop sheet 5 is used for isolating the water pump 16, and avoids water from splashing on the controller 15 when the water pump 16 runs and damaging the controller 15.

The acoustic celotex board 4, water-stop sheet 5 and pump mounting panel 6 all with support fixed connection. The bracket is fixedly connected with the box body. Therefore, the box body, the water pump 16 and the ultrasonic generator 14 are integrated into a whole through the bracket, and the use, the transportation and the storage are convenient.

The utility model discloses the process when carrying out cleaning work is as follows:

the cover 11 of the closed chamber 1 is opened, the air guide pipe is inserted into the fixing hole 13, one end of the air guide pipe passes through the fixing hole 13 and enters the drain chamber 10, the air guide pipe clamp 18 corresponding to the position of the fixing hole 13 is used for clamping the air guide pipe clamp 18, if the number of the fixing holes 13 is large, the redundant fixing holes 13 are blocked by plugs or towels, and then the cover 11 of the closed chamber 1 is closed. The above operation completes the fixation of the gas conduit.

After the air duct is secured, the water inlet pipe of the water pump 16 is placed into a container containing the cleaning liquid, such as a bucket or a pot containing the cleaning liquid. The outlet of the main drain pipe is placed at a drain place such as a drain tank. The pump 16 can then be switched on to deliver the cleaning liquid into the closed chamber 1. The cleaning liquid can only flow out of the air conduit after entering the closed chamber 1. Therefore, the cleaning liquid can wash the inside of the air duct in the flowing process and take away most of substances such as sputum and the like.

The situation in the drainage chamber 10 can be observed in the process of flushing, and whether substances such as sputum and the like are obviously increased or not can be judged according to the observation. Without a significant increase, the water pump 16 can be turned off and the first flush completed by waiting until the liquid level in the discharge chamber 10 completely submerges the air conduit.

After the first flushing is completed, the controller 15 is operated to turn on the ultrasonic generator 14, substances such as sputum and the like still adhered to the air guide pipe are separated from the air guide pipe by utilizing the cavitation effect of the ultrasonic generator 14, and the separated substances such as the sputum and the like can be dissociated in the liquid in the closed chamber 1 or the drainage chamber 10. After the operation of the ultrasonic generator 14 for a certain period of time, the operation of the ultrasonic generator 14 is stopped.

After the ultrasonic generator 14 stops working, the water pump 16 is turned on again, the cleaning liquid input by the water pump 16 can flush free sputum and other substances away from the air duct, and the cleaning liquid also flushes the air duct again at the same time. When no significant sputum or the like is observed entering the drainage chamber 10, the water pump 16 is turned off.

After this flushing, the lid 11 of the closed chamber 1 is opened and the gas line is removed for observation. If the sputum in the tracheal catheter is basically washed clean, manual cleaning can be carried out again, wherein the manual cleaning is used for ensuring that the tracheal catheter is completely cleaned; if there is still significant sputum in the airway at this time, the airway is re-secured and the steps after the first flush, i.e., cavitation of the ultrasonic generator 14 and flushing of free sputum by the water pump 16, are repeated. If the water cannot be completely washed out after repeated 2-3 times, a manual cleaning mode is adopted.

After the purging of the air tube is completed, if there is an air tube to be cleaned, the air tube is directly fixed to the fixing hole 13 and the tube clamp 18, and then the above process is repeated. If there is no air conduit for further cleaning, the remaining cleaning liquid and waste water are drained through the drain pipes in the closed chamber 1 and the drain chamber 10. The drain is closed during the cleaning process. Therefore, the drain pipe is provided with a switch valve.

The utility model discloses can handle the vast majority sputum in the trachea, reduce clearance personnel's working strength. And after most sputum is cleared up, the clearing personnel can not cause strong physiological discomfort when manually clearing the air duct again.
