Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a vaccine cold storage box. Background Art
[0002] A vaccine cold storage box is an important device for storing vaccines. Generally, a vaccine cold storage box consists of a cuboid-shaped box body and a box cover, and a heat-insulating layer is laid inside the box body for heat insulation.
[0003] However, some existing vaccine cold storage boxes usually rely on simple ice packs to refrigerate the vaccines inside the box body when in use. However, this simple refrigeration method has some limitations, resulting in an unsatisfactory refrigeration effect of the cold storage box. First of all, the refrigeration capacity of the ice pack is limited, and it is difficult to maintain a stable low-temperature environment. Secondly, due to the limited refrigeration capacity of the ice pack, as time goes by, the ice pack will gradually melt, resulting in a gradual increase in the temperature inside the box.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0031] Embodiment 1. Please refer to Figures 1-5 , the present utility model provides a technical solution: a vaccine cold storage box, including a box body 1. A cooling copper pipe 101 is fixedly sleeved on the outer surface of the box body 1. An outer cover 102 is fixedly installed on the outer surface of the cooling copper pipe 101. One end of the cooling copper pipe 101 is fixedly embedded with a first water inlet pipe 104. A transfer box 103 is fixedly installed on the top of the first water inlet pipe 104. The bottom of the transfer box 103 is fixedly installed on the left side of the top of the outer cover 102. A one-way valve 105 is fixedly installed inside the first water inlet pipe 104 and near the bottom of the transfer box 103. A second water inlet pipe 106 is fixedly installed near the left side at the center of the top of the transfer box 103. The other end of the cooling copper pipe 101 is fixedly installed with a first water outlet pipe 107. The other end of the first water outlet pipe 107 is fixedly installed with a pump 108. The bottom of the pump 108 is fixedly installed on the top of the outer cover 102. A second water outlet pipe 109 is fixedly embedded at the center of the top of the pump 108. The other end of the second water outlet pipe 109 is fixedly installed on the top of the transfer box 103. A first gasket 110 is fixedly installed on the rear side of the outer cover 102. Hinges 111 are fixedly installed at both ends on the left side of the outer cover 102. A box door 112 is fixedly installed at the rear side of both hinges 111. A second gasket 113 is fixedly installed on the rear side of the box door 112.
[0032] In this embodiment, the staff first injects refrigerant into the transfer box 103 on the outer cover 102 through the second water inlet pipe 106, and then opens the one-way valve 105 to allow the refrigerant to enter the inside of the cooling copper pipe 101 through the first water inlet pipe 104. Thus, the refrigerant circulates inside the cooling copper pipe 101, absorbing the heat inside the box body 1 at the same time, reducing the temperature inside the box body 1, and then refrigerating the box body 1. At the same time, through the power supply system of the pump 108, the pump 108 is turned on, so that when the pump 108 is running, the refrigerant inside the cooling copper pipe 101 is pumped out into the inside of the pump 108 through the first water outlet pipe 107. When the refrigerant is transferred by the pump 108, the refrigerant re-enters the inside of the transfer box 103 through the second water outlet pipe 109. Thus, the refrigerant circulates reciprocally inside the cooling copper pipe 101. And through the settings of structures such as the transfer box 103 and the cooling copper pipe 101, when the device is in use, the circulating flow of the refrigerant inside the cooling copper pipe 101 can be maintained, making the refrigeration process more stable. In this way, it can effectively avoid the situation of the refrigerant stagnating or overheating locally during the refrigeration process, improving the stability and reliability of the refrigeration effect. And this cyclic refrigeration method is more stable than the traditional refrigeration method using bagged refrigerant, and can better maintain the low-temperature environment inside the box body 1.
[0033] Embodiment 2, as Figures 1-5 shown, two first chutes 2 are respectively opened on both sides of the inner wall of the box body 1. The inner surfaces of the four first chutes 2 are all slidably connected with first sliders 201. The four first sliders 201 are divided into two groups. On the opposite sides of the two groups of first sliders 201, storage boxes 202 are fixedly installed. At the centers of both sides of the inner walls of the two storage boxes 202, reset springs 203 are fixedly installed. At the other ends of the four reset springs 203 and inside the storage boxes 202, clamping plates 204 are fixedly installed. At the centers of the bottom sides of the inner walls of the two storage boxes 202, second chutes 206 are opened. At the centers of the bottoms of the four clamping plates 204, second sliders 205 are fixedly installed. The outer surfaces of the four second sliders 205 are all slidably connected to the inner surfaces of the second chutes 206.
[0034] In this embodiment, the staff can pull the storage box 202 backward to drive the first slider 201 to slide backward inside the first chute 2, so that the storage box 202 moves backward synchronously. Then, the clamping plate 204 is bent outward to make the second slider 205 slide backward on the inner surface of the second chute 206, and at the same time drive the return spring 203 to contract. When picking up the vaccine storage bottle and placing it between the two clamping plates 204, the clamping plate 204 is released at the same time to make the return spring 203 reset, thereby driving the clamping plate 204 and the second slider 205 to slide inward synchronously through the second chute 206, so that the clamping plate 204 fits the outer surface of the vaccine storage bottle to clamp and fix the vaccine storage bottle. At the same time, the storage box 202 is pushed inward to make the storage box 202 re-enter the interior of the box body 1, and then the box door 112 is pulled to the left to make the box door 112 flip through the hinge 111, so that the box door 112 is closed with the box body 1. At the same time, the first gasket 110 fits the second gasket 113. And through the settings of structures such as the storage box 202 and the return spring 203, the shaking and collision of the vaccine storage bottle during storage can be prevented, and the integrity and safety of the vaccine can be protected.
[0035] Working principle: During use, the staff first injects refrigerant into the transfer box 103 on the outer cover 102 through the second water inlet pipe 106, and then opens the one-way valve 105 to allow the refrigerant to enter the interior of the cooling copper pipe 101 through the first water inlet pipe 104. As a result, the refrigerant circulates inside the cooling copper pipe 101, absorbing the heat inside the box body 1 at the same time, reducing the temperature inside the box body 1, and thus refrigerating the box body 1. At the same time, through the power supply system of the pump 108, the pump 108 is turned on (it should be noted that the model of the pump 108 is HG-120-C and the power is 120W). When the pump 108 is running, the refrigerant inside the cooling copper pipe 101 is pumped out into the interior of the pump 108 through the first water outlet pipe 107. When the refrigerant is transported through the pump 108, the refrigerant re-enters the interior of the transfer box 103 through the second water outlet pipe 109, thereby realizing the reciprocating circulation of the refrigerant inside the cooling copper pipe 101. And through the settings of structures such as the transfer box 103 and the cooling copper pipe 101, when the device is in use, the circulating flow of the refrigerant inside the cooling copper pipe 101 can be maintained, making the refrigeration process more stable. In this way, it can effectively prevent the refrigerant from stagnating or overheating locally during the refrigeration process, improving the stability and reliability of the refrigeration effect. Moreover, this circulating refrigeration method is more stable than the traditional bagged refrigerant refrigeration method and can better maintain the low-temperature environment inside the box body 1. During use, the staff can pull the storage box 202 backward to drive the first slider 201 to slide backward inside the first chute 2, thereby causing the storage box 202 to move backward synchronously. Then, the clamping plate 204 is pulled outward, causing the second slider 205 to slide backward on the inner surface of the second chute 206 and driving the return spring 203 to contract at the same time. When picking up the vaccine storage bottle and placing it between the two clamping plates 204, and then releasing the clamping plate 204 to allow the return spring 203 to reset, thereby driving the clamping plate 204 and the second slider 205 to slide inward synchronously through the second chute 206, causing the clamping plate 204 to fit against the outer surface of the vaccine storage bottle to clamp and fix the vaccine storage bottle. At the same time, the storage box 202 is pushed inward to make the storage box 202 re-enter the interior of the box body 1. Then, the box door 112 is pulled to the left, causing the box door 112 to flip through the hinge 111, thereby closing the box door 112 with the box body 1. At the same time, the first gasket 110 fits against the second gasket 113. And through the settings of structures such as the storage box 202 and the return spring 203, the shaking and collision of the vaccine storage bottle during storage can be prevented, protecting the integrity and safety of the vaccine.
[0036] The above are only the preferred embodiments of the present utility model, and do not limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still belong to the protection scope of the technical solution of the present utility model.
