[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0019] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0020] like Figure 1-5As shown, a pipette drying device includes an outer shell 1, a drying chamber 2 inside the outer shell, a hot air conveying mechanism 3 connected to the interior of the outer shell and installed on the side of the outer shell, an inlet and outlet 4 connected to the drying chamber and covered with a vent cap 5, and a placement rack 6 for placing pipettes inside the drying chamber. This device is designed for existing pipettes 7 with a pointed tip at one end and an open end. In use, the pipette is first placed with the larger end facing down in the placement rack, then the placement rack is placed in the drying chamber of the outer shell, the vent cap is then covered to cover the inlet and outlet, and finally the hot air conveying mechanism is started for hot air drying.

[0021] In this embodiment, for the sake of reasonable design, the outer shell is cylindrical, and several lifting pads 8 are evenly distributed along the circumference on the bottom of the outer shell. An air inlet 9 is provided in the middle of the bottom of the outer shell. The air inlet is connected to the output port of the hot air conveying mechanism via a pipeline. The lifting pads are used to raise the outer shell so that the pipeline on the output port can extend and connect to the hot air conveying mechanism.

[0022] In this embodiment, in order to realize the flow of gas inside the outer shell, the vent cover includes a cover plate 10, an annular outer sleeve 11 is connected to the outer periphery of the cover plate, and an inner sleeve 12 is provided on the inlet and outlet of the outer shell. The vent cover is fitted onto the inner sleeve through the outer sleeve. A plurality of ventilation holes 13 are opened on the cover plate. When the hot air conveying mechanism conveys hot air into the drying chamber, the hot air will be conveyed from the bottom upward, carrying water vapor, and sent out through the ventilation holes to achieve drying.

[0023] In this embodiment, to facilitate the placement of the pipette and the connection between the placement rack and the drying chamber, the placement rack includes a placement base plate 14. A support rod 15 is connected to the middle of the placement base plate, and a pipette limiting plate 16 is connected to the upper end of the support rod. Several placement components 17 are evenly distributed around the bottom circumference of the drying chamber. These components together form a placement surface for the support rod. Gaps exist between adjacent placement components. The diameters of the placement base plate and the pipette limiting plate are smaller than the diameter of the drying chamber, allowing a portion of the hot air to contact the outer wall of the pipette through the gaps between adjacent placement components and the gaps between the placement base plate, the pipette limiting plate, and the inner wall of the drying chamber, before being output, thus achieving contact with the outer wall of the pipette. The placement base plate is evenly distributed around the circumference... The device has several perforations 18. A pipette large-mouth holder 19 is provided on the upper surface of the placement base plate and on the outer periphery of the perforations. The pipette large-mouth holder is composed of two arc-shaped retaining plates 20. An abutment block 21 is provided on the middle of the outer arc surface of the arc-shaped retaining plate. The pipette limiting plate is provided with a clearance hole 22 for the pipette tube to pass through the perforations. The distance between the pipette limiting plate and the placement base plate is less than the length of the pipette. In use, the large mouth of the pipette extends into the clearance hole and is finally locked into the pipette large-mouth holder composed of the two corresponding arc-shaped retaining plates, thereby fixing the pipette. At the same time, some hot air input from the bottom of the drying chamber enters the large mouth of the pipette through the perforations and is finally discharged from the upper tip of the pipette, thereby drying the inner wall of the pipette.

[0024] In this embodiment, to fix the pipette positioning plate and the placement base plate to both ends of the support rod, annular connecting blocks 23 are symmetrically arranged on the outer periphery of both ends of the support rod. Threaded posts 24 with external threads are connected to both ends of the support rod, and nuts 25 are screwed onto the threaded posts. The pipette positioning plate and the placement base plate are provided with mounting holes 26 corresponding to the threaded posts. The pipette positioning plate and the placement base plate are sleeved on the threaded posts through the mounting holes and clamped to the connecting blocks by the corresponding nuts. Specifically, the pipette positioning plate has a mounting hole in the middle, which is sleeved on the upper threaded post and abuts against the upper connecting block. Then, by rotating the nut, the nut presses down on the pipette positioning plate, thus clamping the pipette positioning plate to the connecting block. The placement base plate has a mounting hole in the middle, which is sleeved on the lower threaded post and abuts against the lower connecting block. Then, by rotating the nut, the nut presses up on the placement base plate, thus clamping the placement base plate to the connecting block.

[0025] In this embodiment, in order to further fix the pipette limiting plate and the placement base plate, the connecting block is provided with a plurality of protrusions 27 corresponding to the pipette limiting plate or the placement base plate, and the pipette limiting plate or the placement base plate is provided with grooves 28 corresponding to the protrusions. That is, through the engagement of the protrusions and the grooves, a stable connection between the pipette limiting plate, the placement base plate and the corresponding connecting block is achieved, and misalignment of the pipette limiting plate and the placement base plate is avoided.

[0026] In this embodiment, in order to further realize the installation between the placement rack and the inside of the drying chamber, the placement assembly includes an arc-shaped placement plate 29. A placement block 30 is provided on the middle of the inner arc surface of the placement plate. The inner arc surface of each placement plate and the placement block together form a circular placement groove corresponding to the placement base plate. That is, the placement base plate is stuck in the circular placement groove to realize the placement of the placement rack.

[0027] In this embodiment, to further facilitate the flow of hot air, a plurality of vent holes 31 are arrayed on both the pipette limiting plate and the placement base plate. To facilitate the lifting of the placement rack and the placement of the pipette after the placement rack is detached, a handle 32 is provided on the upper surface of the pipette limiting plate.

[0028] In this embodiment, in order to achieve hot air delivery, the hot air delivery mechanism includes a housing 33, an installation cavity 34 is provided inside the housing, and an air inlet 35 and an air outlet 36 communicating with the installation cavity are opened at the front and rear ends of the housing. An air intake fan 37 and a resistance heater 38 are arranged in the installation cavity along the gas delivery direction. The air outlet is connected to the air inlet on the bottom of the outer shell through a pipeline. Specifically, a tapered connecting pipe 39 can be installed on the air outlet of the housing. The large opening of the tapered connecting pipe is connected to the air outlet of the housing, and the small opening is connected to the air inlet on the bottom of the outer shell through a pipeline.
