Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of biological detection auxiliary equipment, and in particular relates to an anti-overflow device for a plate washer. Background Art
[0002] The purpose of washing with an ELISA plate washer is to separate the antigen-antibody complex formed on the solid phase carrier from other excess free reaction substances in the liquid. After washing, only specific antibodies are left on the solid phase carrier. Other immunoglobulins and impurities in the serum are washed away during the washing process because they cannot bind to the solid phase antigen. When the staff washes the ELISA plate, they mainly use a plate washer to allow the washing head to absorb the cleaning liquid and inject it into the wells one by one. After soaking for a period of time, the washing head is used to suck out the cleaning liquid in the wells one by one, and then the washing is repeated many times to ensure that the impurities in the wells are cleaned up.
[0003] However, there are some problems with the existing technology: during the cleaning process, some washing heads are often blocked and the water outlet pressure is unstable, which causes the cleaning liquid to accidentally overflow from the ELISA plate, which not only contaminates the plate washer, but also easily causes cross-contamination of subsequent cleaning operations and even damages the plate washer instrument. Therefore, we propose an anti-overflow device for the plate washer. Utility Model Content
[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide an anti-overflow device for a plate washer, which prevents the cleaning liquid from overflowing onto the surface of the plate washer and causing pollution by setting a water containing component.
[0005] The utility model is implemented as follows: an anti-overflow device for a plate washer comprises a machine body, a plate carrier which is matched with the machine body for transverse sliding, a slot for placing an ELISA plate is opened on the plate carrier, a washing head which is matched with the machine body for longitudinal sliding, first square boxes are fixedly installed on both sides of the plate carrier, a water containing assembly is detachably installed inside the first square box, and a baffle assembly is fixedly installed between the tops of the two first square boxes.
[0006] Optionally, the water containing component includes a shell, which is movably mounted inside the first square box, and inclined plates are fixedly mounted on both sides of the top of the shell, and the two inclined plates are arranged in a V shape.
[0007] Optionally, the baffle assembly includes a vertical baffle, the vertical baffle is fixedly connected to the top of the first square box, and the top of the vertical baffle is fixedly connected to a horizontal baffle.
[0008] Optionally, a guide block is fixedly installed on the top of the plate carrier, and a cushion block is fixedly connected to the inner wall of the guide block.
[0009] Optionally, the tops of the guide block and the cushion block are both inclined, and the surfaces of the guide block and the cushion block are provided with a hydrophobic coating.
[0010] Optionally, a second square box located on the left side of the plate carrier is fixedly mounted on the surface of the first square box, and absorbent cotton is fixedly mounted on the inner wall of the second square box.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. By setting up the water-containing component and the baffle component, when the cleaning liquid accidentally overflows from the inside of the ELISA plate, it will be blocked by the vertical block. The water droplets splashed upward by the water flow impacting the vertical block will also be blocked by the horizontal block to prevent splashing. The cleaning liquid will then flow into the inside of the water-containing component instead of flowing to the surface of the body. At the same time, the inclined plate has a good shielding effect on the cleaning liquid inside the shell, making it difficult for the cleaning liquid flowing into the water-containing component to splash outward, thereby ensuring the cleanliness of the body.
[0013] 2. By setting up the second square box and absorbent cotton, after the cleaning operation is completed, water droplets are likely to remain on the water spray pipe of the washing head. The staff can operate the plate carrier and the washing head to move so that the water spray pipe of the washing head is inserted into the absorbent cotton, so that the absorbent cotton can absorb the water droplets adhered to the surface of the water spray pipe of the washing head, thereby preventing the water droplets from falling on the machine body and causing pollution.

DETAILED DESCRIPTION
[0021] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.
[0022] like Figures 1 to 5 As shown, an anti-overflow device for a plate washer provided in an embodiment of the utility model comprises a body 1, a plate carrier 2 which is laterally slidably matched with the body 1 is provided on the body 1, a slot for placing an ELISA plate is provided on the plate carrier 2, a washing head 3 which is longitudinally slidably matched with the body 1 is provided on the body 1, and by setting the cleaning program of the body 1, the plate carrier 2 and the washing head 3 can be slidably matched to inject water and clean the ELISA plate placed inside the slot on the surface of the plate carrier 2, first square boxes 4 are fixedly installed on both sides of the plate carrier 2, a water containing assembly 5 is detachably installed inside the first square box 4, and a baffle assembly 6 is fixedly installed between the tops of the two first square boxes 4.
[0023] When the cleaning liquid for cleaning the ELISA plate accidentally overflows from the ELISA plate, the overflowing cleaning liquid will be blocked by the baffle assembly 6 and flow into the interior of the water containing assembly 5, thereby preventing the wastewater generated by cleaning from flowing onto the body 1 and causing cross contamination when cleaning other ELISA plates subsequently.
[0024] Furthermore, the water containing component 5 includes a housing 501, which is movably mounted inside the first square box 4, and inclined plates 502 are fixedly mounted on both sides of the top of the housing 501, and the two inclined plates 502 are arranged in a V shape. When the cleaning liquid overflowing from the ELISA plate flows to the top of the inclined plates 502, since the two inclined plates 502 are arranged in a V shape, the cleaning liquid can easily flow to the inside of the housing 501, and during the sliding movement of the water containing component 5 with the plate carrier 2, the cleaning liquid inside the housing 501 is also difficult to splash out from the gap between the two inclined plates 502.
[0025] Further, the baffle assembly 6 includes a vertical block 601, which is fixedly connected to the top of the first square box 4, and a horizontal block 602 is fixedly connected to the top of the vertical block 601. The cleaning liquid overflowing from both sides of the ELISA plate is blocked by the vertical block 601, and the water droplets splashed upward by the cleaning liquid impacting the vertical block 601 will be blocked by the horizontal block 602, thereby further achieving a good overflow effect.
[0026] Furthermore, a guide block 7 is fixedly installed on the top of the plate carrier 2, and a cushion block 8 is fixedly connected to the inner wall of the guide block 7. The cushion block 8 is made of a deformable material, such as rubber, so that after the ELISA plate is placed inside the notch on the plate carrier 2, the cushion block 8 is squeezed and fits tightly with the outer wall of the ELISA plate, thereby preventing the cleaning liquid from flowing from the gap between the guide block 7 and the ELISA plate to the plate carrier 2 to cause contamination.
[0027] Furthermore, the tops of the guide block 7 and the cushion block 8 are both inclined, and a hydrophobic coating is provided on the surfaces of the guide block 7 and the cushion block 8. When the cleaning liquid overflowing from the ELISA plate flows outward, it will first pass through the tops of the guide block 7 and the cushion block 8. Since the tops of the guide block 7 and the cushion block 8 are inclined and provided with a hydrophobic layer, the water conductivity is good, and no residual water droplets will affect the subsequent cleaning operation.
[0028] Furthermore, a second square box 9 located on the left side of the plate carrier 2 is fixedly installed on the surface of the first square box 4, and absorbent cotton 10 is fixedly installed on the inner wall of the second square box 9. After the operation of cleaning the ELISA plate is completed, the staff can operate the washing head 3 and the plate carrier 2 to slide and cooperate on the machine body 1, so that the water spray pipe on the washing head 3 moves to the absorbent cotton 10, so that the absorbent cotton 10 absorbs the water droplets remaining on the surface of the water spray pipe of the washing head 3, so as to avoid the water droplets remaining on the water spray pipe of the washing head 3 falling on the surface of the machine body 1 to cause pollution.
[0029] Working principle: After the staff places the ELISA plate on the plate carrier 2, the body 1 is used to clean the ELISA plate according to the program set in the body 1. During the cleaning process, if the cleaning liquid accidentally overflows from the ELISA plate, it will first pass through the top of the guide block 7 and the cushion block 8. Since the top of the guide block 7 and the cushion block 8 are inclined and have a hydrophobic layer, the water conductivity is good, so that the cleaning liquid flows into the water holding component 5. The cleaning liquid on both sides will also be blocked by the baffle assembly 6 to prevent the cleaning liquid from flowing to the surface of the body 1 and causing pollution. After the cleaning operation is completed, water droplets are easily left on the water spray pipe of the washing head 3. The staff can operate the plate carrier 2 and the washing head 3 to move, so that the water spray pipe of the washing head 3 is inserted into the inside of the absorbent cotton 10, so that the absorbent cotton 10 absorbs the water droplets adhered to the surface of the water spray pipe of the washing head 3, thereby preventing the water droplets from falling on the body 1 and causing pollution. Then the water holding component 5 can be taken out to collect the cleaning liquid for dumping.
[0030] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
