Description

Technical Field

[0001] The invention relates to a filterable reagent bottle, which is applied to the field of filtering reagents. Background Art

[0002] Liquid chromatography is a type of separation and analysis technique characterized by the use of a liquid as the mobile phase. The stationary phase can take a variety of forms, such as paper, thin plates, and packed beds. To distinguish between various methods, the stationary phase has been given its own name, such as paper chromatography, thin-layer chromatography, and column liquid chromatography. Filtration of the solution can improve analytical accuracy.

[0003] Existing reagent bottles usually adopt the method of connecting the first bottle body with the second bottle body for filtration, and a filter membrane is set between the first bottle body and the second bottle body, and gravity causes the solution in the upper bottle body to flow into the lower bottle body for filtration. However, this filtration method is too inefficient. Secondly, more reagent bottles are required for filtration operations, and the sealing of the bottle mouths of existing reagent bottles is too poor. In order to solve one or more of the above problems, the development purpose of the present utility model is to develop a reagent bottle that can improve filtration efficiency and is also convenient for sealing the bottle mouth of the reagent bottle.

[0019] As a further improvement, a second convex edge corresponding to the first convex edge is provided at the bottom of the second annular pressure cover member, and a clamping block adapted to be connected to the clamping groove is provided on the second convex edge. The clamping block is rotatably set in the clamping groove to fix the second annular pressure cover member and the cover body, and the sealing portion is folded upward and wraps the receiving portion; when the pressing mechanism moves downward, the second annular pressure cover member drives the second bottle body to slide downward relative to the first bottle body to the bottom of the first bottle body, and the first annular pressure cover member folds the sealing portion downward and buckles it at the lower end of the first surrounding edge.

[0020] As a further improvement, the rack further includes a fixing component arranged in the reagent bottle mounting groove, the fixing component includes a second spring arranged at the bottom of the reagent bottle mounting groove, the other end of the second spring is connected to the abutment block, the side wall of the abutment block is provided with a protrusion, and the inner wall of the bottom of the reagent bottle mounting groove is provided with a special-shaped groove, the protrusion is arranged in the special-shaped groove, and an accommodating cavity is formed between the abutment block and the bottom of the reagent bottle mounting groove, and a first annular airbag that is sleeved with the second spring is provided in the accommodating cavity, the first annular airbag is connected to the second annular airbag, and the second annular airbag is arranged on the inner side wall of the reagent bottle mounting groove near the top.

[0021] The beneficial effects of the present invention are:

[0022] (1) The pressing mechanism moves downward, causing the second bottle body to slide downward relative to the first bottle body, filtering the solution in the first bottle body and allowing the cover body to be sealed and installed on the reagent bottle. The filtration efficiency can be improved by pressing with a hand-pressed punch, and after the filtration is completed, the second bottle body is set in the first bottle body, reducing the use of reagent bottles and making the operation more convenient. The cover body is closed, and the sealing portion is folded downward to enclose the first edge to seal the reagent bottle, preventing the reagent from being exposed to the air and affecting the test results.

[0023] (2) A first peripheral edge is extended outward from the edge of the opening of the first bottle body, and a second peripheral edge is extended outward from the edge of the opening of the second bottle body. When the fixing member touches the bottom of the first accommodating cavity, a gap is reserved between the first peripheral edge and the second peripheral edge. The height of the gap is 3 to 7 mm. When the height of the gap is less than 3 mm, it is difficult to remove the second bottle from the first bottle to clean impurities and replace the filter membrane. If the height of the gap is higher than 7 mm, the sealing part of the cover cannot be stably installed on the first peripheral edge. It is necessary to increase the length of the sealing part to facilitate stable installation and achieve the sealing effect, and the cost of the cover increases. When the height of the gap is 3 to 7 mm, it is not only convenient to remove the second bottle from the first bottle, but also the sealing part can be tightly installed on the first peripheral edge.

[0024] (3) The upper end surface of the cover body is provided with a first arc-shaped recess located on the axis of the cover body, and the diameter of the first arc-shaped recess is R1. The lower end surface of the cover body is provided with a second arc-shaped recess opposite to the first arc-shaped recess, and the diameter of the second arc-shaped recess is R2, wherein R1>R2. The provision of the first arc-shaped recess and the second arc-shaped recess makes the two sides of the cover body relatively thin, which is convenient for inserting the liquid collection needle to collect liquid. However, the defect of the relatively thin side walls is that during the process of withdrawing the liquid collection needle, the insertion port may be folded outward, causing the sealing of the cover body to deteriorate, affecting the storage state of the liquid in the reagent bottle, and causing errors in the detection results. Therefore, the diameter of the first arc-shaped recess is R1, and the diameter of the second arc-shaped recess is R2, wherein R1>R2, reducing the concave depth of the upper end surface of the cover body, deepening the concave depth of the lower end surface of the cover body, and keeping the thickness of the two side walls unchanged, which is convenient for inserting the liquid collection needle to collect liquid. However, reducing the concave depth of the upper end surface of the cover body can effectively prevent the insertion port from folding outward when the liquid collection needle is withdrawn, affecting the detection results.

[0025] (4) The plug includes a straight portion connected to the cover body and a bent portion connected to the straight portion at one end away from the cover body. The angle A between the bent portion and the straight portion is 5 to 10 degrees. Since the reagent bottle of the present invention is not provided with a fixing structure to fix the reagent bottle in the reagent bottle installation groove before pressing, the purpose of providing the bent portion is to facilitate the installation of the plug into the first bottle body. When the angle A between the bent portion and the straight portion is less than 5 degrees, the effect of facilitating the installation of the plug into the second bottle body is not significant. When the angle A between the bent portion and the straight portion is greater than 10 degrees, the installation of the plug is not secure and may become loose. The angle A between the bent portion and the straight portion is 5 to 10 degrees, which not only makes it easy to install the plug into the second bottle body, but also ensures that the plug is securely installed.

[0026] (5) When the pressing mechanism moves downward and the second annular pressing member drives the second bottle body to slide downward relative to the first bottle body to the bottom of the first bottle body, the first annular pressing member folds the sealing portion downward and snaps it onto the lower end of the first surrounding edge. The sealing portion surrounds the first surrounding edge to seal the reagent bottle, preventing the reagent from being exposed to the air and affecting the test results.

[0027] (6) The rack further includes a fixing component arranged in the reagent bottle installation groove, the fixing component includes a second spring arranged at the bottom of the reagent bottle installation groove, the other end of the second spring is connected to the abutment block, the side wall of the abutment block is provided with a protrusion, and the inner wall of the bottom of the reagent bottle installation groove is provided with a special-shaped groove, the protrusion is arranged in the special-shaped groove, and a accommodating cavity is formed between the abutment block and the bottom of the reagent bottle installation groove, and a first annular airbag that is sleeved with the second spring is provided in the accommodating cavity, the first annular airbag is connected to the second annular airbag, and the second annular airbag is provided on the inner side wall of the reagent bottle installation groove near the top. The advantage of setting up the fixing assembly is that there is no need to install and fix the reagent bottle in advance. While the pressure cover plate filters the reagent bottle through a hand-pressed punch, the reagent bottle presses the abutment block downward, and the abutment block compresses the first annular airbag. The protrusion slides in the special-shaped groove (similar to the pressing structure of a ballpoint pen), so that the abutment block remains in a state of compressing the first annular airbag, and the air in the first annular airbag enters the second annular airbag, thereby fixing the reagent bottle. When the filtration is completed, it is convenient to separate the cover body from the pressure cover assembly. When the reagent bottle needs to be taken out, press the reagent bottle again to allow the air in the second annular airbag to enter the first annular airbag, making it easy to take out.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0047] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0048] Reference Figure 1-13 As shown, a press-fitting jig for a filterable reagent bottle 30 includes:

[0049] Shelf positioning seat 10;

[0050] The rack 20 is disposed in the rack positioning seat 10 and includes a rack body and a plurality of reagent bottle mounting slots 21 disposed on the upper end surface of the rack body;

[0051] The reagent bottle 30 is installed in the reagent bottle installation slot 21, including a first bottle body 31 and a second bottle body 32 slidably arranged in the first bottle body 31, a cover 34 is provided on the top of the second bottle body 32, and a filter portion 33 is provided on the bottom of the second bottle body 32;

[0052] The pressing mechanism 40 includes a pressing plate 41, wherein a plurality of placement holes 4121 corresponding to the positions of the bottle openings of the reagent bottles 30 are provided on the lower end surface of the pressing plate 41, and a pressing assembly 43 is provided in each of the placement holes 4121, and the pressing assembly 43 is connected to the cover body 34;

[0053] The pressing mechanism 40 moves downward, causing the second bottle body 32 to slide downward relative to the first bottle body 31 , filtering the solution in the first bottle body 31 and allowing the cover body 34 to be sealed and installed on the reagent bottle 30 .

[0054] Reference Figure 7-8 As shown, the first bottle body 31 includes a first bottle body 311 and a first edge 312 extending outward from the edge of the opening of the first bottle body 311, and a first accommodating cavity 313 is provided in the first bottle body 311; the second bottle body 32 includes a second bottle body 321, and a second accommodating cavity 323 is provided in the second bottle body 321. The filter part 33 includes a plurality of filter holes 331 penetrating the bottom of the second bottle body 321, and a hollow fixing part 332 is connected to the bottom of the second bottle body 321, and a filter membrane 333 is provided between the bottom of the second bottle body 321 and the fixing part 332.

[0055] Reference Figure 6-7As shown, a second rim 322 extends outward from the opening edge of the second bottle body 321. When the fixing member 332 contacts the bottom of the first accommodating cavity 313, a gap is left between the first rim 312 and the second rim 322. The height of this gap is 3 to 7 mm. If the height of this gap is less than 3 mm, it is difficult to remove the second bottle body 32 from the first bottle body 31 to clean impurities and replace the filter membrane. If the height of this gap is greater than 7 mm, the sealing portion 342 of the cover body 34 cannot be stably installed on the first rim 312, and the length of the sealing portion 342 must be increased to ensure stable installation and sealing. This increases the cost of the cover body 34. In this embodiment, the height of this gap is 5 mm. In this case, it is not only convenient to remove the second bottle body 32 from the first bottle body 31, but also the sealing portion 342 can be firmly installed on the first rim 312.

[0056] As a further improvement, a sealing ring 324 is provided on the outer wall of the second bottle body 321, a first annular protrusion 3321 is provided on the inner wall of the fixing piece 332, a first annular groove 325 corresponding to the first annular protrusion 3321 is provided on the side wall of the second bottle body 321, a second annular protrusion 3322 is provided at the bottom of the fixing piece 332, and a second annular groove 326 corresponding to the second annular protrusion 3322 is provided at the bottom of the second bottle body 321. When the filter membrane 333 is set at the bottom of the fixing piece 332, the second bottle body 321 and the fixing piece 332 are buckled together, so that the first annular protrusion 3321 abuts against the first annular groove 325 to fix the fixing piece 332, and the second annular protrusion 3322 is set in the second annular groove 326 and presses the filter membrane 333.

[0057] As a further improvement, the bottom of the second bottle body 321 is curved, and the filter holes 331 are a plurality of through-holes arranged in a circular array at the bottom of the second bottle body 321. The diameter of the filter holes 331 increases from the inside out. To increase the permeability of the filter membrane 333 and achieve better filtering effects, the filter membrane 333 is 0.01 μm thick, which is quite thin. During the filtration process, the filter membrane 333 adheres closely to the bottom of the second bottle body 321 to perform the filtering function. However, when the second bottle body 32 is withdrawn, gas flows from the second accommodating chamber 323 through the filter holes 331, causing the filter membrane 333 to move downward. Due to the curved bottom of the second bottle body 321, the center of the filter membrane 333 is displaced the most. If the filter holes 331 are all uniform in size, the center of the filter membrane 333 is prone to rupture. Therefore, the diameter of the filter holes 331 increases from the inside out to reduce the stress on the center of the filter membrane 333 and prevent rupture.

[0058] As a further improvement, the pressure cover plate 41 includes a first cover plate 411, a universal ball shell 4111 is provided at the upper end of the first cover plate 411, a universal ball 4112 is provided in the universal ball shell 4111, and the universal ball 4112 is connected to a fixing rod 4113 connected to the punch of the hand press. The first cover plate 411 is connected to the second cover plate 412 below, and the lower end of the second cover plate 412 is provided with a placement hole 4121. The upper end surface of the second cover plate 412 is provided with a plurality of cross-arranged ventilation grooves 4122 connected to the placement hole 4121. The ventilation grooves 4122 are connected to the placement hole to facilitate air circulation, thereby facilitating the pressing of the reagent bottle 30.

[0059] Reference Figure 10 As shown, the cover body 34 includes a cover body 341 and a foldable sealing portion 342 arranged at the edge of the cover body 341, the upper end of the cover body 34 is provided with a first ridge 343 arranged in an axial ring array along the cover body 341, the upper end of the first ridge 343 is provided with a card groove 3431, the lower end of the cover body 341 is provided with a plug 344 for sealing the reagent bottle 30, the upper end surface of the cover body 341 is provided with a first arc-shaped recess located on the axis of the cover body 341, the diameter of the first arc-shaped recess 3411 is R1, the lower end surface of the cover body 341 is provided with a second arc-shaped recess opposite to the first arc-shaped recess 3411, the diameter of the second arc-shaped recess 3412 is R2, wherein R1>R2.

[0060] Reference Figure 10 As shown, the plug 344 includes a straight portion 3441 connected to the cover body 341 and a bent portion 3442 disposed at one end away from the cover body 341 and connected to the straight portion 3441. The angle α between the bent portion 3442 and the straight portion 3441 is 5 to 10 degrees. Since the reagent bottle 30 of the present invention is not provided with a fixing structure for fixing the reagent bottle 30 in the reagent bottle mounting groove 21 before pressing, the purpose of providing the bent portion 3442 is to facilitate the installation of the plug 344 into the second bottle body 32. When the angle α between the bent portion 3442 and the straight portion 3441 is less than 5°, the effect of facilitating the installation of the plug 344 into the second bottle body 32 is not significant. When the angle α between the bent portion 3442 and the straight portion 3441 is greater than 10°, the installation of the plug 344 is not secure and may become loose. The angle α between the bent portion 3442 and the straight portion 3441 is 8°, which not only makes it easier for the plug 344 to be installed into the second bottle body 32, but also ensures that the plug 344 is securely installed.

[0061] Reference Figure 3-5As shown, the gland assembly 43 includes a first annular gland member 431 fixed in the placement hole 4121, the first annular gland member 431 includes a mounting portion 4311 and a receiving portion 4312 provided below the mounting portion 4311, the mounting portion 4311 is provided in the placement hole 4121, the receiving portion 4312 has an arc-shaped cross section, the first annular gland member 431 is provided with a first spring 432 connected to the bottom of the placement hole 4121, the other end of the first spring 432 is connected to the second annular gland member 433, the bottom of the second annular gland member 433 is provided with a first flange 343 corresponding to the first flange 343 The second convex edge 4331 is provided with a snap-in block 4332 adapted to connect with the snap-in slot 3431. The snap-in block 4332 is rotatably disposed within the snap-in slot 3431, thereby fixing the second annular gland member 433 and the cover body 34. The sealing portion 342 is folded upward and wraps around the receiving portion 4312. When the pressing mechanism 40 moves downward, the second annular gland member 433 drives the second bottle body 32 to slide downward relative to the first bottle body 31 to the bottom of the first bottle body 31. The first annular gland member 431 folds the sealing portion 342 downward and snaps it onto the lower end of the first rim 312. To facilitate the pressing of the reagent bottle 30, a one-way exhaust hole 345 is provided above the cover body 34 to facilitate the exhaust of air, allowing the pressing mechanism 40 to press the cover body 34.

[0062] As a further improvement, the rack 20 further includes a fixing component 22 arranged in the reagent bottle mounting groove 21, and the fixing component 22 includes a second spring 221 arranged at the bottom of the reagent bottle mounting groove 21, the other end of the second spring 221 is connected to the abutment block 222, and the side wall of the abutment block 222 is provided with a protrusion 2221, and the inner wall of the bottom of the reagent bottle mounting groove 21 is provided with a special-shaped groove 223, and the protrusion 2221 is arranged in the special-shaped groove 223, and a accommodating cavity 224 is formed between the abutment block 222 and the bottom of the reagent bottle mounting groove 21, and a first annular airbag 225 that is sleeved on the second spring 221 is provided in the accommodating cavity 224, and the first annular airbag 225 is connected to the second annular airbag 226, and the second annular airbag 226 is arranged on the inner side wall of the reagent bottle mounting groove 21 near the top.
