[0002] Enzymes are common protein molecules that act as efficient catalysts in biological reactions. Enzymes not only work quickly and effectively, they are also degradable and can effectively increase the reaction rate of biochemical processes.

[0003] The existing Chinese patent authorization announcement number: CN219709470U, discloses a sterile inoculation device for enzyme preparations, which belongs to the field of enzyme preparation auxiliary production technology. A sterile inoculation device for enzyme preparations, including a sterilization box, a box cover hinged on one side of the top of the sterilization box, a connecting sleeve fixed in the middle of the top of the box cover, and a push tube provided at the top of the connecting sleeve corresponding to the sterilization box. The utility model facilitates the pouring of materials through the feed tube, and facilitates the pushing of poured materials into the sterilization box through the arrangement of the push rod, piston and push tube, thereby reducing the large amount of bacteria entering when the tank mouth is fully opened. The arrangement of the tube cover achieves the effect of shielding the feed tube, reducing the contact between external bacteria and materials, and reducing the entry of impurity bacteria. The arrangement of the pump body, box body, connecting pipe and nozzle, etc., achieves the full disinfection and sterilization of the push tube, feed tube and push rod, and reduces the adhesion of bacteria on the surface before and after the use of the device.

[0004] The above-mentioned sterile inoculation device still has the following problems when in use: the above-mentioned sterile inoculation device requires additional force to push the material into the sterilization box when in use, which makes the operation more complicated when feeding.

[0005] Therefore, it is necessary to invent a sterile inoculation device for enzyme preparation to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide a sterile inoculation device for enzyme preparations, so as to solve the problem in the above-mentioned background technology that the above-mentioned sterile inoculation device requires additional force to push the material into the sterilization box when in use, which makes the operation more cumbersome when feeding.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sterile inoculation device for an enzyme preparation, comprising an enzyme preparation box, an outer support frame fixedly connected to the outer wall of the lower end of the enzyme preparation box, a feed port opened on the top of the enzyme preparation box, a feed pipe fixedly connected to the top of the feed port, and a sealing plug movably installed on the top end of the feed pipe, a sealing block suspended in the interior of the enzyme preparation box, an arc-shaped surface provided on the lower end of the sealing block, and a mounting rod fixedly connected to the outer wall of the sealing block, and a connecting ring block fixedly connected to the top of the mounting rod, the connecting ring block and the top wall of the enzyme preparation box are movably connected by a reset spring, and the reset spring is movably sleeved on the outer ring of the mounting rod, and the outer ring of the mounting rod is fixedly sleeved with sealing gasket 1 and sealing gasket 2.

[0008] Preferably, the feed port is in a truncated cone shape, and the inner diameter of the top end of the feed port is smaller than the inner diameter of the bottom end of the feed port, and the inner wall of the feed port is a smooth arc surface, which facilitates the bacteria to enter the enzyme preparation box.

[0009] Preferably, the sealing block is in the shape of a truncated cone, and the arc-shaped outer wall of the top part of the sealing block is in contact with the arc-shaped inner wall of the bottom part of the feed port to achieve a sliding connection. In the initial state, the sealing block presses against the bottom port of the feed port to prevent bacteria from contacting the inside of the enzyme preparation box.

[0010] Preferably, there are two mounting rods, and the two mounting rods are symmetrically arranged on both sides of the sealing block with reference to the vertical center axis of the sealing block as the symmetry axis, and the two mounting rods extend through the through holes reserved in the top plate of the enzyme preparation box to the outside of the enzyme preparation box, and the inner wall of the through hole is in contact with the outer wall of the mounting rod to achieve a sliding connection, thereby ensuring the stability of the sealing block movement.

[0011] Preferably, the sealing gasket 1 is located inside the enzyme preparation box, and the sealing gasket 1 is tightly fitted with the lower end of the through hole;

[0012] The second sealing gasket is located on the outer wall of the enzyme preparation box and is fixedly connected to the bottom wall of the connecting ring block, thus ensuring that the through hole of the sealing block has good sealing performance in both the initial state and the active state.

[0013] Preferably, the upper end of the reset spring is fixedly connected to the bottom wall of the connecting ring block, and the other end of the reset spring is fixedly connected to the top wall of the enzyme preparation box. The reset spring can subsequently perform a reset movement to mobilize the sealing block to reset after activity.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] The utility model injects bacteria into the feed pipe by opening the sealing plug. Under the action of the weight of the bacteria, the sealing block is pressed downward, so that the sealing block moves downward and gradually leaves the feed port, thereby opening the passage connecting the feed port and the enzyme preparation box. In this way, it is convenient for the bacteria to directly enter the enzyme preparation box without manual assistance. At the same time, the sealing block is in a frustum shape. When the bacteria enters the enzyme preparation box along the sealing block, the bacteria fall into the enzyme preparation box in a divergent shape, ensuring that the bacteria are added more evenly.

[0016] At the same time, when the sealing block moves downward, under the linkage action of the mounting rod, the connecting ring block fixedly connected to the mounting rod moves synchronously, so that the movement state of the sealing block can be observed intuitively. At the same time, the subsequent reset spring is no longer affected by external pressure to achieve reset movement, driving the sealing block to reset and re-block the feed port to prevent external bacteria from entering the enzyme preparation box.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] The utility model provides Figure 1-4 The aseptic inoculation device of an enzyme preparation shown includes an enzyme preparation box 1, an outer support frame 2 is fixedly connected to the outer wall of the lower end of the enzyme preparation box 1, a feed port 3 is opened on the top of the enzyme preparation box 1, and a feed pipe 4 is fixedly connected to the top of the feed port 3, and a sealing plug 5 is movably installed on the top end of the feed pipe 4, a sealing block 6 is suspended inside the enzyme preparation box 1, an arc-shaped surface 13 is provided at the lower end of the sealing block 6, and the outer wall of the sealing block 6 is fixedly connected to a mounting rod 7, and the top of the mounting rod 7 is fixedly connected to a connecting ring block 9, the connecting ring block 9 and the top wall of the enzyme preparation box 1 are movably connected by a reset spring 12, and the reset spring 12 is movably sleeved on the outer ring of the mounting rod 7, and the outer ring of the mounting rod 7 is fixedly sleeved with a sealing gasket 10 and a sealing gasket 2 11.

[0026] The feed port 3 is in a truncated cone shape, and the inner diameter of the top end of the feed port 3 is smaller than that of the bottom end, and the inner wall of the feed port 3 is a smooth arc surface, which facilitates the bacteria to enter the enzyme preparation box 1.

[0027] The sealing block 6 is in the shape of a truncated cone, and the arc-shaped outer wall of the top part of the sealing block 6 is in contact with the arc-shaped inner wall of the bottom part of the feed port 3 to achieve a sliding connection. In the initial state, the sealing block 6 presses against the bottom port of the feed port 3 to prevent bacteria from contacting the inside of the enzyme preparation box 1.

[0028] There are two mounting rods 7, and the two mounting rods 7 are symmetrically arranged on both sides of the sealing block 6 with reference to the vertical center axis of the sealing block 6 as the symmetry axis, and the two mounting rods 7 pass through the through hole 8 reserved in the top plate of the enzyme preparation box 1 and extend to the outside of the enzyme preparation box 1. The inner wall of the through hole 8 is in contact with the outer wall of the mounting rod 7 and a sliding connection is realized to ensure the stability of the movement of the sealing block 6.

[0029] The sealing gasket 10 is located inside the enzyme preparation box 1, and the sealing gasket 10 is tightly fitted with the lower end of the through hole 8;

[0030] The second sealing gasket 11 is located on the outer wall of the enzyme preparation box 1 and is fixedly connected to the bottom wall of the connecting ring block 9, thereby ensuring that the through hole 8 of the sealing block 6 has good sealing performance in both the initial state and the active state.

[0032] Working principle: When using a sterile inoculation device for an enzyme preparation, first inject the bacteria into the feed tube 4 by opening the sealing plug 5. After the bacteria accumulate inside the feed tube 4, the bacteria collectively press down the sealing block 6 under the action of weight, so that the sealing block 6 moves downward under the weight and gradually leaves the feed port 3. At this time, the channel connecting the feed port 3 and the enzyme preparation box 1 is opened, which facilitates the bacteria to directly enter the enzyme preparation box 1. The sealing block 6 is in a truncated cone shape, and the bacteria diverge along the curved outer wall of the sealing block 6 to enter the enzyme preparation box 1, which can ensure that the bacteria are added more evenly.

[0033] At the same time, when the sealing block 6 moves downward, the connecting ring block 9 fixedly connected to the mounting rod 7 moves synchronously, so that the movement state of the sealing block 6 can be observed intuitively. At the same time, the subsequent reset spring 12 is no longer affected by external pressure to achieve reset movement, driving the sealing block 6 to reset and re-block the feed port 3 to prevent external bacteria from entering the enzyme preparation box 1.
