Description

Technical Field

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

[0002] Ultrasonic cleaning utilizes the cavitation, acceleration and straight-forward flow effects of ultrasound in liquids to directly and indirectly affect liquids and dirt, so that the dirt layer is dispersed, emulsified and peeled off to achieve the cleaning purpose.

[0003] Most existing ultrasonic cleaners do not directly have an air-drying / hot-air-drying mechanism. Instead, an air-drying / hot-air-drying step is added after ultrasonic cleaning of medical devices to perform drying. For example, the utility model patent with the announcement number CN211938189U discloses a drying cover for an ultrasonic cleaner, which can be installed and air-dried on ultrasonic cleaners without a drying system. However, when a large number of instruments are placed on the ultrasonic cleaning rack, the drying cover is difficult to effectively dry the instruments stacked on the bottom, resulting in long drying time and incomplete drying. The invention patent with the announcement number CN115889330B discloses a mechanical centrifugal drying component for an ultrasonic cleaner, which includes a box body, an inner shell fixedly connected to the inside of the box body, an ultrasonic component 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 cleaning is completed, the cleaning frame can be driven to rotate at high speed directly by the motor and the height of the cleaning frame is adjusted to achieve centrifugal drying. However, for slender medical instruments such as scissors, tweezers, and scalpels, the drying process will not only cause the instruments to be placed in a disorderly manner, but it is also easy for the instruments to be thrown out and their tips to get stuck in the frame holes of the ultrasonic cleaning rack, making it inconvenient to remove the instruments later.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example: Please read Figure 1-4 As shown, the present invention provides an ultrasonic cleaning and drying device for medical devices, comprising a housing 1, a cleaning tank 2 and an ultrasonic generator disposed within the housing 1, and a drying cover (not shown) disposed on the top of the housing 1. The drying cover is a conventional cover with a drying function. An electric heater 202 is fixedly disposed within the cleaning tank 2, and a liftable bracket 501 is disposed within the cleaning tank 2. The drying cover can be adaptively formed with an escape area for the bracket 501, and the bracket 501 is used to support the ultrasonic cleaning frame. A telescopic cylinder 3 is fixedly mounted on the rear side of the housing 1. The output end of the telescopic cylinder 3 is connected to a connecting piece 4 extending forward and across the rear wall of the housing. The bottom of the connecting piece 4 is connected to a lifting frame 5. The lifting frame 5 is disposed within the cleaning tank 2, and the bracket 501 is fixedly connected to the bottom of the lifting frame 5.

[0025] On the basis of the above embodiment, a cross frame 6 is set above the bracket 501, and positioning plates 7 are fixedly provided on the front and rear parts of the left and right sides of the cross frame 6. A groove rail is opened on the upper part of the positioning plate 7, and a first rotating shaft 704 is rotatably provided on the lower part of the positioning plate 7. A rotating rod 703 is fixedly connected to the first rotating shaft 704, and the other end of the rotating rod 703 is rotatably connected to the V-shaped rod 710 through the second rotating shaft 705. The opposite ends of the left and right V-shaped rods 710 are rotatably provided with a third rotating shaft 706, and the third rotating shaft 706 passes through the groove rail and the moving trajectory is limited by the groove rail. The opposite sides of the left and right V-shaped rods 710 are provided with connecting plates 8, which are arranged in the front and rear directions. Several negative pressure wind collecting hoods 802 are installed on the connecting plates 8, and a negative pressure fan (not shown in the figure) is installed on the rear side of the outer shell 1. The negative pressure wind collecting hood 802 is connected to the negative pressure fan through a soft air duct.

[0026] Furthermore, connecting legs 801 are fixedly provided on both the front and rear sides of the connecting plate 8, and the other ends of the connecting legs 801 are connected to the opposite ends of the left and right V-shaped rods 710. Tooth plates 205 are fixedly provided on the front and rear upper parts of the left and right sides of the cleaning tank 2. A first gear 708 is fixedly sleeved on the first rotating shaft 704, and a second gear 709 is rotatably connected to the cross frame 6. The second gear 709 is meshed with the first gear 708, and after the second gear 709 is raised, it meshes 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, thereby driving the V-shaped rod 710 and the connecting plate 8 with the connecting legs 801 to rotate counterclockwise, and then can be flipped to the bottom of the left part of the bracket 501 with the negative pressure air collecting hood 802 facing upward.

[0027] It should be noted that when the second gear 709 engages the toothed plate 205, the first gear 708 drives the rotating rod 703 to deflect toward the left or right outer side. Driven by the second rotating shaft 705 and guided by the movement trajectory of the third rotating shaft 706, the V-shaped rod 710 rotates the connecting plate 8 from the left or right outer side of the bracket 501 to the bottom of the bracket 501. The height of the toothed plate 205 must ensure that the negative pressure air collection cover 802 remains above the liquid level after the connecting plate 8 is rotated to the bottom of the bracket 501.

[0028] In addition to the above embodiment, guide wheels 601 are installed on both sides of the bottom of the lifting frame 5. Vertically distributed V-shaped channel steel 201 is installed on the rear wall of the cleaning tank 2. The guide wheels 601 and the V-shaped channel steel 201 are arranged to roll with each other. Because the lifting frame 5 is relatively high, the bracket 501 is located at the bottom of the lifting frame 5 and has a certain load-bearing capacity, which can easily cause the bracket 501 to deviate backward and downward. By adding guide wheels 601 and V-shaped channel steel 201, the levelness and stability of the bracket 501 can be improved.

[0029] Based on the above embodiment, the groove rail is composed of an arcuate groove 701 and a smooth groove 702. The arcuate groove 701 is in the shape of a circular arc, and the center of the arcuate groove 701 is not co-located with the axis of the first rotating shaft 704. The arcuate groove 701 and the smooth groove 702 are transitionally connected. It should be noted that when the third rotating shaft 706 moves to the end of the smooth groove 702 away from the arcuate groove 701, the second rotating shaft 705 is approximately located below and slightly outside the third rotating shaft 706. This allows the connecting plate 8 to be in a nearly horizontal state when it is flipped to the bottom of the bracket 501. At the same time, when the reverse operation is performed, it is convenient for the connecting plate 8 to flip from the bottom of the bracket 501 back to the left or right side of the bracket 501.

[0030] Based on the above embodiment, vertically distributed vertical plates 203 are fixedly disposed within the cleaning tank 2 at positions corresponding to the first rotating shaft 704. The two vertical plates 203 have their facing sides fixedly connected to tooth plates 205. The two vertical plates 203 have their opposing sides fixedly connected to limit plates 204. The third rotating shaft 706 is coaxially connected to limit rods 707, which abut against the facing sides of the two limit plates 204. When the second gear 709 is fully engaged with the lower end of the tooth plate 205, the limit rods 707 are disengaged from or have already disengaged from the limit plates 204. By providing the limit plates 204, the third rotating shaft 706 can be vertically limited by the limit plates 204 after the connecting plate 8 flips to the left or right sides of the bracket 501. This improves the stability of the connecting plate 8 in its vertical position and prevents it from deflecting due to gravity. After the connecting plate 8 is flipped to the bottom of the bracket 501 , the position and state of the connecting plate 8 can be relatively stabilized by the restriction of the second gear 709 and the first gear 708 by the toothed plate 205 .

[0031] In addition to the above embodiment, a proximity sensor (not shown) is provided on connecting plate 8. The proximity sensor preferably has a detection range of 150 mm. The proximity sensor is electrically connected to a microcontroller, which is in turn electrically connected to the telescopic cylinder 3, the electric heater 202, and the negative pressure blower. When the telescopic cylinder 3 drives the bracket 501 upward until the horizontal frame 6 is positioned on the bracket 501, the ultrasonic cleaning rack is within the detection range of the proximity sensor. At this point, the microcontroller triggers the negative pressure blower to turn on, thereby achieving the suction and drying effect of the negative pressure air collection hood 802.

[0032] Among them, the lower part of the vertical plate 203 is fixed with a bottom plate 206, and the bottom plate 206 extends to the bottom of the horizontal frame 6; when the horizontal frame 6 is set on the bottom plate 206, the negative pressure air collection cover 802 is located above the liquid surface. When the bracket 501 is further lowered to be submerged in the water, the horizontal frame 6 will separate from the bracket 501 to prevent the connecting plate 8 from also being submerged in the water. It should be noted that the horizontal frame 6 should be provided with a certain counterweight so that under its own weight, the second gear 709 can engage the gear plate 205 and drive the connecting plate 8 to flip from the bottom of the bracket 501 to the left or right outer side of the bracket 501, so as to fully realize the mutual switching of the negative pressure air collection cover 802 from the left and right sides and the bottom position of the ultrasonic cleaning frame.

[0033] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
