Description

Technical Field

[0001] The present invention relates to the technical field of vaccine rewarming equipment, and in particular to a temperature-uniform vaccine rewarming device. Background Art

[0002] In order to prevent deterioration, inactivated animal vaccines are usually stored in refrigerators. When it is necessary to vaccinate livestock, the vaccines need to be taken out of the refrigerator and then warmed to between 20°C and 25°C using a water bath or by hand. If the vaccine is not warmed up before injection or is not warmed up properly, it will cause great stress reactions to livestock. Since water baths can make the vaccine warm more evenly than by hand, water baths are usually used to warm the vaccine. Vaccines will be inactivated at high temperatures, that is, it is impossible to quickly warm the vaccine using a high-temperature water bath, so it takes a long time for the vaccine to warm up. In order to save the rewarming time, the vaccine is usually placed in a water bath after being taken out of the refrigerator, and then the water bath is carried to the poultry and livestock vaccination site to prepare for injection. However, during the movement, the water bath liquid in the water bath shakes, causing part of the water bath liquid to splash onto the bottle mouth of the vaccine. When the vaccine is extracted through a syringe, the syringe will first contact the water bath liquid adhering to the bottle mouth of the vaccine, which is easy to contaminate the vaccine. At the same time, the vaccine that needs to be rewarmed is directly placed upright in the water bath. When the water bath shakes, the water bath liquid in the water bath shakes, which is easy to impact the vaccine and cause the vaccine to fall over. Summary of the invention

[0021] Please refer to Figure 4-Figure 6The middle part of the extrusion disk 6 is limited in the upper and lower positions and is sealed and slidably connected with a several-shaped piece 14. The several-shaped piece 14 is made of elastic material. When the height of the several-shaped piece 14 decreases, its length increases. A plurality of equally spaced limiting grooves 141 are provided on the connecting rod 5 close to the side of the height adjusting piece 11. The limiting grooves 141 are limited and matched with adjacent several-shaped pieces 14 to adapt to vaccine bottles of different heights. The several-shaped piece 14 is made of elastic material. The force required for the deformation of the several-shaped piece 14 is less than the elastic force of the spring between the height adjusting piece 11 and the adjacent second extrusion cylinder 10, so as to control the order of deformation of the several-shaped piece 14 and movement of the extrusion disk 6.

[0022] Please refer to Figure 4-Figure 7 An L-shaped member 15 is fixedly connected to the side of the L-shaped member 14 away from the adjacent limiting groove 141. An annular groove 151 is provided on the upper part of the extrusion member 8. The lower part of the L-shaped member 15 passes through the adjacent first extrusion cylinder 7 and cooperates with the adjacent annular groove 151 to prevent the annular airbag 9 from expanding and hindering the downward movement of the vaccine bottle when the vaccine bottle moves downward. The thickness of the annular groove 151 is greater than the thickness of the L-shaped member 15 on the side close to the adjacent first extrusion cylinder 7, which is used to facilitate the L-shaped member 15 to limit the adjacent extrusion member 8.

[0023] Please refer to Figure 3 , Figure 8 and Fig. 9 Three annularly distributed T-shaped pieces 16 are fixedly connected to the upper side of the support ring 4, and a sealing rod 17 is sealingly and slidingly connected inside the T-shaped piece 16.

[0024] Please refer to Figure 2 , Figure 3 and Fig. 9A squeezing ball 19 is fixedly connected to the lower side of the support ring 4 and close to the central axis of the outer shell 1. The squeezing ball 19 is a hemisphere. A motor 20 is fixedly connected to the upper side of the piston rod 13. A shaking plate 21 is fixedly connected to the output shaft of the motor 20. The shaking plate 21 is in contact with the middle part of the lower side of the support plate 3. A plurality of hemispherical grooves 211 distributed in an annular shape are provided on the shaking plate 21. The hemispherical grooves 211 are squeezed and matched with adjacent squeezing balls 19. The support plate 3 is fixedly connected with an annular elastic block 22 symmetrically distributed up and down. The symmetrically distributed elastic blocks 22 are squeezed and matched with the side of the adjacent support ring 4 away from the adjacent squeezing ball 19 to push the adjacent support ring 4 to reset. A reset cylinder 23 is fixedly connected to the middle of the upper side, and a reset disk 24 is sealed and slidably connected to the lower part of the reset cylinder 23. A reset member 25 is rotatably connected to the middle of the upper side of the reset disk 24. The reset member 25 is limitedly matched with the reset cylinder 23. The reset member 25 is composed of a cylinder, a knob and two limit posts. A groove corresponding to the shape of the cylinder and the two limit posts of the reset member 25 is arranged on the upper side of the reset cylinder 23. Initially, the two limit posts of the reset member 25 are both located in the reset cylinder 23, and the two limit posts of the reset member 25 do not correspond to the grooves on the reset cylinder 23. The T-shaped member 16 on one side of the support ring 4 is connected to the lower part of the reset cylinder 23 through a conduit.

[0025] When it is necessary to vaccinate the poultry and livestock, the farmer takes out the vaccine from the refrigerator and rotates the sealing cover 2 to make the sealing cover 2 lose contact with the outer shell 1, and then inserts the vaccine into the outer shell 1 in sequence (which will be explained later with a group of parts on the left side of the outer shell 1). The farmer inserts the vaccine into the support ring 4 and presses it downward. The vaccine first contacts the L-shaped member 14 and squeezes the L-shaped member 14 to deform. The deformation of the L-shaped member 14 causes its right part to move to the right and lose contact with the adjacent limiting groove 141, thereby releasing the limit on the adjacent connecting rod 5. When the L-shaped member 14 is deformed, its left part drives the L-shaped member 15 to move left, and the lower part of the L-shaped member 15 passes through the first extrusion cylinder 7 and enters the annular groove 151, limiting the extrusion member 8. Then the vaccine contacts the extrusion disk 6 and squeezes it downward.

[0026] As the extrusion plate 6 moves downward, the extrusion plate 6 drives the height adjusting member 11 downward, compressing the spring between the height adjusting member 11 and the second extrusion cylinder 10 (hereinafter, this spring is referred to as the spring adjacent to the second extrusion cylinder 10). At the same time, the extrusion plate 6 drives the first extrusion cylinder 7 and the extrusion member 8 downward, and compresses the spring between the extrusion member 8 and the adjacent connecting rod 5 (hereinafter, this spring is referred to as the spring adjacent to the extrusion member 8). As the height adjusting member 11 moves downward, the hydraulic oil in the power chamber 111 enters the height adjusting chamber 131 through the adjacent conduit. The hydraulic oil in the height adjusting chamber 131 pushes the piston rod 13 upward. The piston rod 13 drives the support plate 3 to move upward through the motor 20 and the shaking plate 21, so that the liquid level of the water bath liquid in the water bath chamber 301 is always coplanar with the lower side of the support plate 3.

[0027] As the vaccine is squeezed, the extrusion disc 6 moves downward and moves to the middle of the support ring 4 at the bottleneck of the vaccine, the vaccine is stopped, and then the several-shaped part 14 quickly resets, and the right side of the several-shaped part 14 moves to the left, but because the right side of the several-shaped part 14 does not correspond to the adjacent limiting groove 141, the right side of the several-shaped part 14 contacts the adjacent connecting rod 5 at this time and cannot be completely reset, but the several-shaped part 14 always has a tendency to reset, and at the same time, the extrusion disc 6 is slowly moved upward by the reset action of the adjacent spring of the second extrusion cylinder 10 (limited by the flow rate of the hydraulic oil in the adjacent conduit of the second extrusion cylinder 10, the extrusion disc 6 moves slowly upward), as the extrusion disc 6 drives the several-shaped part 14 to move slowly upward, the right side of the several-shaped part 14 gradually corresponds to the adjacent limiting groove 141, at this time, the right side of the several-shaped part 14 moves to the left under its reset action and enters the adjacent limiting groove 141, limiting the connecting rod 5, at this time, the extrusion disc 6 stops moving upward, and at the same time, the bottleneck of the vaccine just passes through the support ring 4 (as shown in the attached Figure 2 status of vaccines).

[0028] When the L-shaped member 14 is reset, the left side of the L-shaped member 14 moves right under its reset action, and drives the L-shaped member 15 to move right, the L-shaped member 15 loses contact with the annular groove 151, and the limit on the extrusion member 8 is released. At this time, the extrusion member 8 moves upward under the action of its adjacent spring, and squeezes the gas in the extrusion chamber 801 into the annular airbag 9 through the conduit, so that the annular airbag 9 expands and contacts the lower side of the vaccine bottleneck, preventing the water bath liquid in the water bath chamber 301 from overflowing through the space between the support ring 4 and the vaccine when the device is vibrated.

[0029] After the annular airbag 9 expands and fits with the vaccine, the excess gas in the annular airbag 9 enters the three T-shaped pieces 16 through the adjacent conduits. The gas in the T-shaped piece 16 pushes the adjacent sealing rod 17 to move. The sealing rod 17 drives the adjacent rubber block 18 to move toward the direction close to the central axis of the support ring 4, and finally contacts the bottleneck of the vaccine to limit the vaccine. The above steps are then repeated until all support rings 4 are filled with vaccines. The farmer then tightens the sealing cover 2 again, then starts the electric heating wire in the outer shell 1 and sets the motor 20 to start at intervals. The electric heating wire heats the water bath liquid in the water bath chamber 301. , and keep the water bath liquid at a fixed temperature. At the same time, the output shaft of the motor 20 drives the shaking plate 21 to rotate at intervals. The shaking plate 21 squeezes the squeezing ball 19 upward through the hemispherical groove 211, so that the support ring 4 swings counterclockwise along its ball center (the rotation perspective in this article is from front to back). At the same time, the support ring 4 squeezes the elastic block 22 to deform, and when the next hemispherical groove 211 contacts the squeezing ball 19, the support ring 4 swings clockwise and resets under the push of the elastic block 22. In this way, the support ring 4 drives the adjacent vaccine and all parts on it to swing, shake the vaccine, make each position in the vaccine evenly heated, and improve the temperature recovery efficiency.

[0030] After arriving at the livestock vaccination site, the farmer waits for the temperature of the vaccine in the device to rise, then turns off the electric heating wire and the motor 20, and unscrews the sealing cover 2. The farmer then turns the reset member 25 so that the limit column on the reset member 25 corresponds to the groove on the reset cylinder 23, and then pulls the reset member 25 upward. The reset member 25 drives the reset disk 24 to move upward, and extracts the gas in the adjacent T-shaped member 16 and the gas in the annular airbag 9 connected to the adjacent T-shaped member 16 through the adjacent conduit, so that the gas in the T-shaped member 16 drives the adjacent sealing rod 17 to move, and the sealing rod 17 drives the adjacent rubber block 18 to move and lose contact with the vaccine. At the same time, the annular airbag 9 gradually recovers its deformation and loses contact with the vaccine.

[0031] After the annular airbag 9 loses contact with the vaccine, the farmer presses the vaccine lightly, and the vaccine squeezes the L-shaped member 14 to deform and repeat the above steps, so that the right side of the L-shaped member 14 loses contact with the adjacent limit groove 141 and releases the limit on the adjacent connecting rod 5. At this time, the vaccine tends to move upward due to the action of the adjacent spring of the second extrusion cylinder 10. Then the farmer keeps squeezing the vaccine and moves the vaccine slowly upward until the extrusion disk 6 is about to reset. Since the lower part of the L-shaped member 15 is located in the first extrusion cylinder 7, the extrusion member 8 is restricted from resetting. Under the action of the adjacent spring of the second extrusion cylinder 10, the extrusion disk 6 continues to move upward and reset, and stretches the adjacent spring of the extrusion member 8. Then the farmer removes the vaccine. At this time, the L-shaped member 14 resumes its deformation, and at the same time, the L-shaped member 14 drives the L-shaped member 15 to move out of the first extrusion cylinder 7. The extrusion member 8 moves downward and resets under the action of its adjacent spring.

[0032] When the extrusion disk 6 moves upward, the spring adjacent to the extrusion member 8 gradually resets, and then the spring adjacent to the extrusion member 8 pulls the extrusion member 8 downward relative to the first extrusion cylinder 7, so that the volume inside the extrusion chamber 801 increases, and the gas in the reset cylinder 23 is extracted through the adjacent conduit, the annular airbag 9 and the T-shaped member 16, so that the reset disk 24 moves downward. After the extrusion disk 6 and the T-shaped member 14 are reset, the extrusion member 8 moves downward and resets relative to the first extrusion cylinder 7. Then the farmer takes out the vaccine in the device in turn, resets the reset disk 24 and the reset member 25, and then rotates the reset member 25 to misalign the limit column of the reset member 25 with the groove on the reset cylinder 23. Then the farmer injects the vaccine into the poultry and livestock.

[0033] When the vaccine is warmed up by the water bath method, since the vaccine and the water bath liquid are in a relatively static state, the heat transfer efficiency between the water bath liquid and the vaccine is low, causing the vaccine to warm up slowly.

[0034] Example 2: Based on Example 1, please refer to Figure 3 and Fig. 9 , and also includes a plurality of stirring plates 26 distributed in an annular shape, and the stirring plates 26 are fixedly connected to the lower side of the shaking plate 21.

[0035] When the shaking plate 21 rotates, the shaking plate 21 drives the several stirring plates 26 on the lower side thereof to rotate. The rotation of the stirring plates 26 drives the water bath liquid in the water bath chamber 301 to rotate, thereby changing the water bath liquid in contact with the vaccine, improving the heat exchange efficiency between the water bath liquid and the vaccine, and thereby shortening the time required for the vaccine to return to temperature.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
