Description

Technical Field

[0001] The present invention relates to the technical field of cleaning devices, and particularly to an ultrasonic cleaning and air-drying device for medical devices. Background Art

[0002] Ultrasonic cleaning utilizes the cavitation effect, acceleration effect and rectilinear flow effect of ultrasonic waves in a liquid to directly and indirectly act on the liquid and dirt, so that the dirt layer is dispersed, emulsified and peeled off to achieve the cleaning purpose.

[0003] Most of the existing ultrasonic cleaners do not directly set an air-drying / hot air-drying mechanism. After ultrasonic cleaning of medical devices, an air-drying / hot air-drying step is added to perform the drying function. For example, the utility model patent with the publication number CN211938189U discloses a drying cover for an ultrasonic cleaner, which can be installed on an ultrasonic cleaner without a drying system and air-dried. However, when there are many instruments placed on the ultrasonic cleaning rack, it is very difficult for this drying cover to effectively dry the instruments stacked at the bottom, so there are problems of long drying time and incomplete drying. The invention patent with the publication number CN115889330B discloses a mechanical centrifugal drying assembly for an ultrasonic cleaner, which includes a box body, an inner shell fixedly connected inside the box body, an ultrasonic assembly fixedly connected to the bottom of the inner cavity of the box body, and a drying mechanism fixedly connected to the top of the box body. After the cleaning is completed, the motor can be directly operated and the height of the cleaning frame can be adjusted to drive the cleaning frame to rotate at a high speed to achieve centrifugal drying. However, for slender medical devices such as scissors, forceps, and scalpels, during the drying process, not only will the placement of the instruments become disordered, but it is also easy for the instruments to be thrown out and their tips to get stuck in the holes of the ultrasonic cleaning rack, making it inconvenient to take out the instruments later.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment: Please refer to Figures 1-4 As shown in the figure, the present invention provides a medical device ultrasonic cleaning and air-drying device, including an outer shell 1. A cleaning tank 2 and an ultrasonic generator are arranged inside the outer shell 1. A drying cover (not shown in the figure) is covered on the top of the outer shell 1. The drying cover is an existing cover body with an air-drying function. An electric heater 202 is fixedly arranged in the cleaning tank 2, and a liftable bracket 501 is arranged in the cleaning tank 2. The drying cover can adaptively form an avoidance area for the bracket 501. The bracket 501 is used to carry an ultrasonic cleaning rack. Among them, a telescopic cylinder 3 is fixedly installed on the rear side of the outer shell 1. The output end of the telescopic cylinder 3 is connected with a connecting piece 4 that extends forward and crosses the rear wall of the shell. The bottom of the connecting piece 4 is connected with a lifting frame 5. The lifting frame 5 is arranged in the cleaning tank 2, and the bracket 501 is fixedly connected with the bottom of the lifting frame 5.

[0019] On the basis of the above embodiment, a cross frame 6 is arranged above the bracket 501. Positioning plates 7 are fixedly arranged at the front and rear parts on the left and right sides of the cross frame 6. A groove rail is opened at the upper part of the positioning plate 7. A first rotating shaft 704 is rotatably arranged at the lower part of the positioning plate 7. A rotating rod 703 is fixedly connected to the first rotating shaft 704. The other end of the rotating rod 703 is rotatably connected with a V-shaped rod 710 through a second rotating shaft 705. Third rotating shafts 706 are rotatably arranged at the opposite ends of the two V-shaped rods 710. The third rotating shafts 706 pass through the groove rail and are limited by the groove rail to move along a track. Connecting plates 8 are arranged on the opposite sides of the two V-shaped rods 710. The connecting plates 8 are arranged along the front and rear directions. A plurality of negative pressure air collecting hoods 802 are installed on the connecting plates 8. A negative pressure fan (not shown in the figure) is installed on the rear side of the outer shell 1. The negative pressure air collecting hoods 802 are connected to the negative pressure fan through flexible air ducts.

[0020] Further, connecting feet 801 are fixedly provided on both the front and rear sides of the connecting plate 8, and the other ends of the connecting feet 801 are correspondingly connected to the opposite ends of the left and right V-shaped rods 710. Tooth plates 205 are fixedly provided on the front, rear, upper parts of the left and right sides in the cleaning tank 2. A first gear 708 is fixedly sleeved on the first rotating shaft 704. A second gear 709 is rotatably connected to the cross frame 6. The second gear 709 is meshed with the first gear 708, and when the second gear 709 rises, it is meshed with the tooth plate 205 for transmission. In this way, when the cross frame 6 moves upward to the height of the tooth plate 205, taking the second gear 709 at the left rear as an example, the second gear 709 rotates clockwise, and the first gear 708 rotates counterclockwise, so as to drive the V-shaped rod 710 and the connecting plate 8 with the connecting feet 801 to rotate counterclockwise together, and then can be turned to directly below the left part of the bracket 501 with the negative pressure air collecting hood 802 facing upward.

[0021] It should be noted that when the second gear 709 is meshed with the tooth plate 205, the first gear 708 drives the rotating rod 703 to deflect leftward / rightward outward. Under the drive of the second rotating shaft 705 and the movement track limitation of the third rotating shaft 706, the connecting plate 8 is turned from the left / right outside of the bracket 501 to below the bracket 501. The height of the tooth plate 205 needs to ensure that the negative pressure air collecting hood 802 is still above the liquid level after the connecting plate 8 is turned to below the bracket 501.

[0022] On the basis of the above embodiments, guide wheels 601 are installed on both sides of the bottom of the lifting frame 5. A V-shaped channel steel 201 distributed vertically is provided on the rear side wall in the cleaning tank 2. The guide wheels 601 are arranged to roll with the V-shaped channel steel 201. Since the lifting frame 5 is relatively high and the bracket 501 is located at the bottom of the lifting frame 5 and has a certain load-bearing capacity, it is easy to cause the bracket 501 to shift backward and downward. By adding the guide wheels 601 and the V-shaped channel steel 201, the levelness and stability of the bracket 501 can be improved.

[0023] On the basis of the above embodiments, the groove track is composed of an arc-shaped groove 701 and a flat sliding groove 702. The arc-shaped groove 701 is in an arc shape, and the center of the arc-shaped groove 701 does not coincide with the axis of the first rotating shaft 704, and the arc-shaped groove 701 and the flat sliding groove 702 are connected in a transitional manner. It should be noted that when the third rotating shaft 706 moves to the end of the smooth groove 702 far from the arc-shaped groove 701, the second rotating shaft 705 is generally located at a position below and outside the third rotating shaft 706, so that the connecting plate 8 can be in a nearly horizontal state when it is turned to below the bracket 501, and at the same time, it is convenient for the connecting plate 8 to be turned back from below the bracket 501 to the left and right sides of the bracket 501 during reverse operation.

[0024] On the basis of the above embodiments, a vertically distributed vertical plate 203 is fixedly arranged in the cleaning tank 2 corresponding to the position of the first rotating shaft 704, and a toothed plate 205 is fixedly connected to the facing sides of the two vertical plates 203. Limiting plates 204 are fixedly connected to the opposite sides of the two vertical plates 203, and a limiting rod 707 is coaxially connected to the third rotating shaft 706, and the two limiting rods 707 are correspondingly abutted against the facing sides of the two limiting plates 204; when the second gear 709 just meshes with the lower end of the toothed plate 205, the limiting rod 707 just disengages or has disengaged from the limit of the limiting plate 204. By setting the limiting plate 204, the third rotating shaft 706 can be vertically limited by the limiting plate 204 after the connecting plate 8 is flipped to the left and right sides of the bracket 501, so that the stability of the connecting plate 8 maintaining a vertical state can be improved, thereby avoiding the deflection of the connecting plate 8 due to the action of gravity. And after the connecting plate 8 is flipped to the lower part of the bracket 501, the position and state of the connecting plate 8 can be relatively stabilized by the limitation of the toothed plate 205 on the second gear 709 and the first gear 708.

[0025] On the basis of the above embodiments, a proximity sensor (not shown in the figure) is provided on the connecting plate 8. The detection range of the proximity sensor can be preferably 150 mm. The proximity sensor is electrically connected to a microcontroller, and the microcontroller is electrically connected to the telescopic cylinder 3, the electric heater 202 and the negative pressure fan. When the telescopic cylinder 3 drives the bracket 501 upward until the cross frame 6 is erected on the bracket 501, the ultrasonic cleaning rack is within the detection range of the proximity sensor. At this time, the negative pressure fan can be triggered to turn on through the microcontroller, so as to realize the suction and air drying function of the negative pressure air collecting cover 802.

[0026] Wherein, a bottom plate 206 is fixedly arranged at the lower part of the vertical plate 203, and the bottom plate 206 extends below the cross frame 6; when the cross frame 6 is erected on the bottom plate 206, the negative pressure air collecting cover 802 is above the liquid level. When the bracket 501 further descends into the water, the cross frame 6 will be separated from the bracket 501 to prevent the connecting plate 8 from also entering the water. It should be noted that a certain weight should be set for the cross frame 6 so that under its own weight, the second gear 709 can mesh with the toothed plate 205 and drive the connecting plate 8 to flip from the lower part of the bracket 501 to the left / right outside of the bracket 501, so as to completely realize the mutual switching of the negative pressure air collecting cover 802 between the left and right sides and the lower part of the ultrasonic cleaning rack.

[0027] 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.
