[0001] The utility model relates to the technical field of medical device cleaning devices, and particularly relates to a ventilator pipeline cleaning device. Background Technique

[0002] The ventilator pipeline usually includes a spiral middle part and connection ports at both ends of the spiral pipe. These connection ports are designed to be socket-fixed to the corresponding joints in the ventilator system by elastic deformation. In order to keep the ventilator pipeline clean, a wire brush with a brush is traditionally used as a cleaning brush. The cleaning brush enables the brush to reach the inside of the spiral pipe for cleaning operations through the deformation of the wire. However, in actual operation, the cleaning process usually relies on manual control of the insertion and rotation actions of the cleaning brush. Due to human factors, the cleaning may not be thorough, and the cleaning effect is not good. In view of the above problems, the utility model proposes a ventilator pipeline cleaning device with good cleaning effect. Content of the Utility Model

At the same time, the two filtering components are used to limit the scouring medium in the flushing channel, so that the scouring medium will not enter the water storage container, which can narrow the movement range of the scouring medium and enable the scouring medium to collide with the inner wall of the ventilator pipeline more times in the same time, further improving the scouring effect;

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Embodiment: Please refer to Figures 1 to 4 , a ventilator pipeline cleaning device is provided according to an embodiment of the present utility model, including two water storage containers 10, a plurality of flushing media 20, a filter component 30, and a cleaning liquid conveying structure. The water storage containers 10 are adapted to contain the cleaning liquid. A connector 11 is provided on each water storage container 10. The two connection ports 51 of the ventilator pipeline 50 can be respectively socket-fixed to the two connectors 11 to form a flushing channel between the two connectors 11; the flushing media 20 are in granular form and are arranged in the flushing channel; the filter component 30 is arranged at the communicating position of the water storage container 10 and the connector 11 and can allow the cleaning liquid to pass through and restrict the passage of the flushing media 20; the cleaning liquid conveying structure is configured to be able to push the cleaning liquid and the flushing media 20 to reciprocate in the flushing channel.

[0030] For the ventilator pipeline cleaning device adopting the above structure, the connection ports 51 at both ends of the ventilator pipeline 50 to be cleaned are respectively sleeved on the connection heads 11 of the two water storage containers 10. Since the connection port 51 itself has elasticity, it can ensure the tightness and sealing performance when the connection port 51 is connected to the connection head 11. After connection, the cleaning liquid conveying structure is used to make the cleaning liquid and the scouring medium 20 flow reciprocally in the flushing channel. Because the ventilator pipeline 50 is generally spiral, therefore, the cleaning liquid and the scouring medium 20 will flow along a spiral path in the ventilator pipeline 50, which can effectively scour each position on the inner wall of the ventilator pipeline 50, reduce the cleaning dead corners, and achieve a better flushing effect. In addition, the scouring medium 20 is restricted in the flushing channel by the two filtering components 30, so that the scouring medium 20 will not enter the water storage container 10, which can narrow the movement range of the scouring medium 20, make the scouring medium 20 collide with the inner wall of the ventilator pipeline 50 more times in the same time, and further improve the scouring effect.

[0031] In this exemplary embodiment, as Figure 1 and Figure 2 shown, the water storage container 10 has the ability of elastic deformation in the vertical direction, and the two water storage containers 10 are used as the cleaning liquid conveying structure. Specifically in this embodiment, the water storage container 10 includes a bottom wall 12, a top wall 13, and a wavy side wall 14 connecting the bottom wall 12 and the top wall 13, and the side wall 14 can elastically expand and contract in the vertical direction. Specifically, both the bottom and top wall surfaces are circular, and the side wall surface presents a wavy cylindrical structure. The bottom, top wall surfaces and the side wall surface together form the water storage container 10. In actual operation, the operator can achieve the effect of pushing the cleaning liquid and the scouring medium 20 to move reciprocally in the flushing channel by pinching the end of the ventilator pipeline 50 and periodically and alternately compressing the two water storage containers 10 in the vertical direction. It should be noted that, in order to ensure that the cleaning liquid and the scouring medium 20 can move smoothly in the flushing channel, before connecting the ventilator pipeline 50 to the connection heads 11 of the two water storage containers 10, at least one water storage container 10 should be compressed to some extent, so that there is space for the air in the ventilator pipeline 50, which is convenient for subsequent operation of the water storage container 10. Of course, in other embodiments, the two water storage containers 10 can also adopt spherical or ellipsoidal rubber air bags, and by alternately squeezing these two rubber air bags in any direction, the goal of pushing the cleaning liquid and the scouring medium 20 to move reciprocally in the flushing channel can also be achieved.

[0032] In order to facilitate the replacement of the cleaning liquid, in this embodiment, a drain valve 15 is provided at the bottom of the side wall 14 of the water storage container 10.

[0033] In this exemplary embodiment, as Figure 2 and Figure 4As shown, the connector 11 is fixedly provided on the top wall 13. The filtering component 30 is in a rod shape and arranged vertically. The filtering component 30 has a lower end portion 31 fixedly connected to the bottom wall 12 and an upper end portion 32 movably inserted into the connector 11. The upper end portion 32 has a liquid passing hole 320 that communicates the connector 11 with the water storage container 10. Specifically in this example, the connector 11 and the top wall 13 can be an integral structure. The lower end portion 31 and the upper end portion 32 of the filtering component 30 are both columnar and can be an integral structure. The number of the liquid passing holes 320 is six, and the six liquid passing holes 320 are equidistantly distributed along the circumferential direction of the upper end portion 32. It can be understood that with the filtering component 30 having the above structure, firstly, it can effectively prevent the scouring medium 20 from entering the water storage container 10 and limit its movement range, thereby increasing the collision frequency between the scouring medium 20 and the inner wall of the ventilator pipeline 50 within the same time; secondly, the filtering component 30 has a positioning and guiding function, that is, during the vertical compression and resetting process of the water storage container 10, the filtering component 30 can limit the lateral swing of the top wall 13 of the water storage container 10 and the connector 11, providing guiding support for the operator when compressing and resetting the water storage container 10, and ensuring more stable operation to convey the cleaning liquid; finally, since the scouring medium 20 is easily worn during the process of cleaning the ventilator pipeline 50 and may need to be replaced regularly, and when replacing, the worn scouring medium 20 in the connector 11 must be taken out. When it is necessary to take out the scouring medium 20 from the connector 11, the water storage container 10 can be compressed, and the upper end portion 32 of the filtering component 30 is used to push the scouring medium 20 in the connector 11 outwards, facilitating its taking out and replacement, that is, the setting of the filtering component 30 also helps with the replacement work of the scouring medium 20.

[0034] In the present exemplary embodiment, as Figure 1 、 Figure 2 and Figure 3 shown, an elastic support rod member 60 is connected between two water storage containers 10, and the middle part of the elastic support rod member 60 can arch upwards and support the ventilator pipeline 50. Specifically in this example, the elastic support rod member 60 is made of spring steel. The middle part of the elastic support rod member 60 arches upwards and bends into an arc shape, and the length of the elastic support rod member 60 is approximately the same as the length of the ventilator pipeline 50. It can be understood that during the process of flushing the ventilator pipeline 50, the elastic support rod member 60 is placed below the ventilator pipeline 50 to maintain its arc shape and prevent the pipeline from bending arbitrarily. This helps the smooth flow of the scouring medium 20 in the pipeline, thereby promoting the effective cleaning of the ventilator pipeline 50. Moreover, keeping the ventilator pipeline 50 in an arc shape can also ensure that the scouring medium 20 accurately falls back into the connector 11 when the flushing is completed.

[0035] In the present exemplary embodiment, as Figure 3As shown, on both sides of the elastic support rod 60, there are a plurality of arc-shaped limit claws 61 for fixing the ventilator pipeline 50 on the elastic support rod 60. Specifically in this example, the limit claws 61 and the elastic support rod 60 are of an integral structure. The number of the limit claws 61 is five, and the five limit claws 61 are equidistantly distributed in the middle of the elastic support rod 60. It is easy to understand that through the plurality of limit claws 61, the ventilator pipeline 50 can be effectively fixed on the elastic support rod 60, thereby improving the stability of the ventilator pipeline 50 on the elastic support rod 60, and facilitating the disassembly and installation of the ventilator pipeline 50 on the elastic support rod 60. In other embodiments, ropes can also be used to fix the ventilator pipeline 50 on the elastic support rod 60.

[0036] In the present exemplary embodiment, as Figure 3 shown, annular socket ends 62 are fixedly provided at both ends of the elastic support rod 60, and the socket ends 62 are movably sleeved on the connection head 11. Specifically in this example, the socket ends 62 are perpendicularly connected to the ends of the elastic support rod 60 at an angle of 90 degrees, and the socket ends 62 and the elastic support rod 60 are of an integral structure. It can be understood that by providing the socket ends 62 at both ends of the elastic support rod 60, the connection between the elastic support rod 60 and the connection head 11 can be facilitated.

[0037] In the present exemplary embodiment, as Figure 1 and Figure 2 shown, the ventilator pipeline 50 cleaning device further includes a base 70. Two water storage containers 10 are arranged on the base 70 at intervals, and the distance between the two water storage containers 10 can be adjusted. Specifically in this example, the two water storage containers 10 are fixed on the base 70 by magnetic attraction. More specifically, magnets are provided on the bottom walls 12 of the two water storage containers 10, and the base 70 is a plate made of iron, so that the two water storage containers 10 can be adsorbed at any part of the base 70, and the distance between the two water storage containers 10 can be adjusted. It can be understood that arranging the two water storage containers 10 at intervals on a base 70 can stabilize the positions of the water storage containers 10 and facilitate the compression of the water storage containers 10; in addition, by setting the distance between the two water storage containers 10 to be adjustable, it can be appropriately adjusted according to the length of the ventilator pipeline 50 to meet the cleaning requirements of ventilator pipelines 50 of different lengths.

[0038] In this exemplary embodiment, the density of the flushing medium 20 is the same as that of the cleaning liquid. By using a flushing medium 20 with a density matching that of the cleaning liquid, the influence of buoyancy and gravity on the movement of the flushing medium 20 can be effectively reduced. Specifically, during the upward movement of the flushing medium 20 along the ventilator pipeline 50, its own gravity must be overcome. If the gravity significantly exceeds the buoyancy, the kinetic energy of the flushing medium 20 will be dissipated excessively; while during the downward movement of the flushing medium 20 along the ventilator pipeline 50, the buoyancy from the cleaning liquid needs to be overcome. If the buoyancy is much greater than its own gravity, it will also lead to excessive dissipation of the kinetic energy of the flushing medium 20. Therefore, by adjusting the density of the flushing medium 20 to be basically the same as that of the cleaning liquid, the buoyancy and gravity can cancel each other out, thereby minimizing the consumption of the kinetic energy of the flushing medium 20 by these two forces to the greatest extent.

[0039] In this exemplary embodiment, as Figure 1 and Figure 2 shown, the cleaning liquid delivery structure is a pump 40, and the pump 40 is connected between two water storage containers 10. Specifically in this example, the pump 40 selected can be a peristaltic pump. By controlling the intermittent forward and reverse rotation of the peristaltic pump motor, the reciprocating movement of the cleaning liquid and the flushing medium 20 in the flushing channel can be achieved. The control of the forward and reverse rotation of the peristaltic pump motor belongs to the prior art and will not be elaborated here. When the pump 40 is used as the cleaning liquid delivery structure, the material for making the water storage container 10 can be selected as a rigid material. It can be understood that using the pump 40 as the cleaning liquid delivery structure can effectively reduce the labor intensity when cleaning the ventilator pipeline 50 and improve the cleaning efficiency. It should be noted that using a water storage container 10 with elastic deformation ability in the vertical direction as the cleaning liquid delivery structure and using the pump 40 as the cleaning liquid delivery structure can exist simultaneously, and the operator can choose manual or electric drive for the cleaning liquid to flow.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
