DETAILED DESCRIPTION

[0033] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0034] like Figures 1 to 5 As shown, the present invention provides a micro smear preparation device, comprising a housing 1, in which a smear mechanism and a transfer mechanism are arranged;

[0035] Smear agencies include:

[0036] A smear sheet assembly, the smear sheet assembly is used to smear the glass slide 2;

[0037] A horizontal moving component, on which the glass slide 2 is placed, is used to drive the glass slide 2 to move horizontally;

[0038] A vertical moving assembly, on which the smear sheet assembly is mounted, and the vertical moving assembly is used to drive the smear sheet assembly to move up and down;

[0039] The transfer mechanism comprises a filter cup 3 and a suction assembly connected to the filter cup 3 , and a transfer film is arranged in the filter cup 3 .

[0040] When the present invention is in use, the smear sheet assembly moves up and down through the vertical moving assembly. When the smear sheet assembly contacts the glass slide 2 on the horizontal moving assembly, the horizontal moving assembly is used to drive the glass slide 2 to move forward and backward, so that the glass slide 2 can be prepared by smearing. When preparing by transfer, a specimen mixture is poured into the filter cup 3, and the specimen mixture in the filter cup 3 is sucked away by the suction assembly, so that the specimen will remain on the transfer film on the filter cup 3, and then it can be removed and manually transferred. The present invention can select different preparation methods, and the equipment has the advantages of small size, light weight, and convenient carrying. The equipment includes smearing preparation and transfer preparation, which can be prepared separately or simultaneously.

[0041] To further optimize the solution and facilitate the replacement of consumables during the coating process, the coating sheet assembly includes:

[0042] A magnet 4, which is magnetically fixed on an iron sheet on the vertical moving component;

[0043] Two fixing clips 5, the two fixing clips 5 are respectively arranged on both sides of the magnet 4, and a connecting piece is arranged between the two fixing clips 5, and the two fixing clips 5 are installed on the magnet 4 through the connecting piece;

[0044] The rubber sheet 6 is provided with a hole matched with the connecting piece, and the rubber sheet 6 is installed between the two fixing clips 5 through the connecting piece.

[0045] When in use, the smear sheet assembly is installed on the vertical moving assembly through the magnet 4, and the rubber sheet 6 is installed between the two fixed clips 5 through a connecting piece and installed on the magnet 4. When the rubber sheet 6 needs to be replaced, just remove the magnet 4 from the iron sheet, disassemble the two fixed clips 5, and then remove the rubber sheet 6.

[0046] A further optimized solution is provided to facilitate the connection between the two fixed clips 5 and the connection between the connecting parts and the magnet 4. The connecting parts are clip magnets 7. One end of the clip magnets 7 is fixedly connected to a fixed clip 5. A hole matching the clip magnets 7 is provided on the other fixed clip 5. The clip magnets 7 are fixed to the magnets 4 by magnetic attraction.

[0047] When in use, the rubber sheet 6 is put on the clip magnet 7 through the hole set on it, and the clip magnet 7 is passed through the hole on another fixed clip 5 to clamp the rubber sheet 6, and then the clip magnet 7 is attracted to the magnet 4, and the connection between the fixed clip 5, the rubber sheet 6 and the magnet 4 is completed.

[0048] To further optimize the solution, in order to ensure the stability of the installation of the rubber sheet 6, a groove matching the clip magnet 7 is opened on the top of the magnet 4, and the clip magnet 7 is clamped in the groove.

[0049] By providing a groove on the magnet 4, when the magnet 4 and the clip magnet 7 are connected, in addition to the attraction between the two magnets 4, the structural engagement can also be achieved, thereby reducing the falling off of the two magnets 4 when an external force is applied.

[0050] A further optimized solution is provided. To facilitate the up and down movement of the smear sheet assembly, the vertical moving assembly includes a screw motor 8 and a linear slide 9. The bottom end of the linear slide 9 is fixedly mounted on the bottom plate of the shell 1. A first slider 10 is slidably connected to the linear slide 9. The screw motor 8 is fixedly mounted on the linear slide 9, and a screw rod 11 is fixedly connected to the output shaft of the screw motor 8. The screw rod 11 is threadedly connected to the first slider 10. A mounting head 12 is mounted on the first slider 10. A slot 13 is provided at the bottom end of the mounting head 12. Both the iron sheet and the smear sheet assembly are mounted in the slot 13.

[0051] Through the setting of the card slot 13, the smear sheet assembly is installed in the card slot 13, and the groove wall of the card slot 13 can be used to limit the two fixed clips 5, so as to limit the distance between the two fixed clips 5, thereby avoiding the loosening of the fixation of the two fixed clips 5 on the rubber sheet 6 when the rubber sheet 6 is used for smearing, resulting in uneven smearing.

[0052] A further optimized solution is to facilitate driving the glass slide 2 to move horizontally. The horizontal moving component includes a motor module 14 and a glass slide groove 15. The motor module 14 is fixedly mounted on the bottom plate of the shell 1. The glass slide 2 is placed in the glass slide groove 15. The glass slide groove 15 is moved horizontally by the motor module 14.

[0053] According to a further optimized solution, the motor module 14 is a lead screw assembly, and the glass slide groove 15 is installed on a slider of the lead screw assembly.

[0054] To further optimize the solution and facilitate transfer-type film making, the suction assembly includes a diaphragm pump 16 installed in the housing 1 , the liquid inlet end of the diaphragm pump 16 is connected to a filter head 18 through a hose 17 , and the filter cup 3 is installed on the filter head 18 .

[0055] To further optimize the solution, in order to facilitate the automatic control of the device, a controller 19 is provided in the housing 1 , and the smearing mechanism and the transfer mechanism are both electrically connected to the controller 19 .

[0056] According to a further optimized solution, a first function button 20 and a second function button 21 are installed on the outer wall of the housing 1. The first function button 20 is used to control the operation of the smear mechanism, and the second function button 21 is used to control the operation of the transfer mechanism.

[0057] The micro smear preparation device provided by the present invention has the following working principle:

[0058] When the present invention is in use, the screw motor 8 is used to drive the lead screw 11 to drive the first slider 10 to move downward on the linear slide 9 until the rubber sheet 6 on the mounting head 12 contacts the glass slide 2 in the glass slide groove 15, and then the lead screw assembly is used to drive the glass slide groove 15 to move in the horizontal direction, so that smear-type slide preparation can be achieved; when performing transfer-type slide preparation, the specimen mixture is poured into the filter cup 3, and the specimen mixture in the filter cup 3 is sucked away by the suction assembly, so that the specimen will remain on the transfer film on the filter cup 3, and then it is removed and manually transferred.

[0059] The invention can be operated by an adapter or a lithium battery driven device, is easy to carry, and can be used for film making work anywhere.

[0060] The above are only preferred specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
