Description

Technical Field

[0001] This application relates to the technical field of vaccine thawing, and particularly to a seesaw-type thawing device. Background Art

[0002] Vaccines are biological preparations made from bacteria, viruses, tumor cells, etc. that can cause the body to produce specific immunity. When transporting vaccines, it is necessary to freeze the vaccines. Generally, the vaccines are packed in vaccine bags and transported by refrigeration to achieve the effect of preserving the vaccines.

[0003] Before use, it is necessary to thaw the frozen vaccines in the vaccine bags. The usual thawing method is to place the vaccine bags on the workbench and then heat the vaccine bags through a heating device to achieve the purpose of thawing. However, the efficiency of this thawing method is relatively low and needs to be further improved. Utility Model Content

[0004] In order to improve the thawing efficiency, this application provides a seesaw-type thawing device.

[0005] A seesaw-type thawing device provided by this application adopts the following technical solutions:

[0006] A seesaw-type thawing device includes a cabinet, a placement rack, a heating component, and a power telescopic member. The placement rack is used to load vaccine bags. The placement rack is rotatably arranged on the cabinet. The heating component is arranged on the placement rack and is used to heat the vaccine bags. The power telescopic member is arranged on the cabinet. The power telescopic member includes a fixed part and a movable part slidably arranged at one end of the fixed part. The fixed part is rotatably connected to the cabinet, and the movable part is rotatably connected to the placement rack.

[0007] By adopting the above technical solutions, when the movable part of the power telescopic member extends and retracts repeatedly, the placement rack can swing back and forth, so that while the heating component heats the vaccine bags, the vaccine bags can swing, which helps the vaccine bags to be heated more evenly and also enables the liquid melted in the vaccine bags to be in a flowing state, thereby accelerating the thawing efficiency.

[0008] Optionally, a bearing plate is arranged on the placement rack. There are a plurality of bearing plates arranged at intervals along the height direction of the placement rack. The top surface of the bearing plate is used to place vaccine bags, and ventilation holes are opened on the bearing plate.

[0009] By adopting the above technical solutions, one vaccine bag can be placed on each bearing plate, so the placement rack can thaw the vaccines in multiple vaccine bags at the same time, which helps to improve the working efficiency. The setting of the ventilation holes enables the bottom of the vaccine bags to be heated sufficiently, which helps to ensure the thawing efficiency.

[0010] Optionally, a plurality of heating components are provided, and each heating component corresponds to a carrier plate. The heating component includes a blower and a heating element. The air outlet side of the blower faces the inner side of the placement rack, and the heating element is located on the air outlet side of the blower.

[0011] By adopting the above technical solution, the heating element can heat the air blown by the blower, thereby thawing the vaccine bags placed on the placement rack.

[0012] Optionally, a protective door is movably connected to the cabinet body, and an observation window is provided on the protective door.

[0013] By adopting the above technical solution, it is convenient to put in or take out the vaccine bags after opening the protective door; the setting of the observation window facilitates the operator to observe the thawing situation of the vaccine bags, which is more convenient.

[0014] Optionally, a blowing component is provided on the placement rack. The blowing component includes an exhaust pipe and a hose. The exhaust pipe is located above the carrier plate. A plurality of exhaust ports are spaced along the length direction of the exhaust pipe, and the exhaust ports face the carrier plate. One end of the hose is connected to the exhaust pipe, and the other end of the hose is arranged on the air outlet side of the blower.

[0015] By adopting the above technical solution, on the one hand, the blower can blow hot air on both sides of the vaccine bags placed on the carrier plate through the air outlet, and on the other hand, it can send a part of the hot air into the hose and the exhaust pipe, and then blow hot air downward through the exhaust ports on the exhaust pipe, so as to blow hot air on the top of the vaccine bags, which can expand the contact area between the hot air and the vaccine bags, thereby enhancing the thawing effect on the vaccine bags.

[0016] Optionally, the exhaust pipe is slidably arranged on the placement rack. A driving component is provided on the placement rack. The driving component includes a support rod, a rotary power component and a screw rod. The support rod is fixedly connected to the end of the exhaust pipe. The rotary power component is arranged on the placement rack. The screw rod is coaxially fixedly connected to the output end of the rotary power component, and the screw rod is in threaded connection with the support rod.

[0017] By adopting the above technical solution, after the rotary power component is started, it can drive the screw rod to rotate. The screw rod drives the support rod to slide, and the support rod drives the exhaust pipe to slide, so that the hot air discharged from the exhaust pipe can contact each part of the top of the vaccine bags, thereby ensuring the melting efficiency of the vaccines in the vaccine bags.

[0018] Optionally, a vibration mechanism is provided on the placement rack. The vibration mechanism includes a connecting rod, a rotating ring, a toothed block, a first elastic member, a transmission assembly, and a power assembly. The connecting rod is parallel to the screw rod. The connecting rod is rotatably arranged on the placement rack. The rotating ring is sleeved outside the connecting rod. The transmission assembly is arranged between the rotating ring and the connecting rod. The transmission assembly enables the connecting rod to drive the rotating ring to rotate in only one direction. The toothed block is slidably arranged on the placement rack. Teeth for meshing with the toothed block are arranged on the outer wall of one side of the rotating ring. The first elastic member is connected between the toothed block and the placement rack. The first elastic member causes the top end of the toothed block to tend to press against the bottom wall of the bearing plate. The power assembly is arranged between the screw rod and the connecting rod. The power assembly is used to drive the connecting rod to rotate.

[0019] By adopting the above technical solution, the power assembly drives the connecting rod to rotate. When the connecting rod rotates, it drives the rotating ring to rotate. When the teeth on the rotating ring mesh with the toothed block, the rotation of the rotating ring can cause the toothed block to move downward. When the teeth on the rotating ring disengage from the toothed block, the first elastic member causes the toothed block to move upward and makes the top end of the toothed block move to a state where it abuts against the bottom wall of the bearing plate. The connecting rod continues to rotate, which can cause the toothed block to intermittently move upward and strike the bearing plate, thereby vibrating the bearing plate, which helps to improve the melting efficiency of the vaccine in the vaccine bag.

[0020] Optionally, the transmission assembly includes a ratchet wheel, a ratchet pawl, and a second elastic member. The ratchet wheel is coaxially and fixedly connected to the connecting rod. The ratchet pawl is rotatably arranged on the inner wall of the rotating ring. The second elastic member is connected between the ratchet pawl and the inner wall of the rotating ring. The second elastic member causes the ratchet pawl to press against the ratchet wheel.

[0021] By adopting the above technical solution, when the connecting rod rotates, it can drive the ratchet wheel to rotate. With the cooperation of the ratchet wheel and the ratchet pawl, when the connecting rod rotates forward, the ratchet pawl presses against the ratchet wheel, so the rotating ring can rotate in the same direction as the connecting rod, and the rotation of the rotating ring causes the toothed block to move downward. When the connecting rod rotates backward, the ratchet pawl can rotate and give way, so the rotating ring remains stationary. At this time, the toothed block is in a state where it presses against the bottom wall of the bearing plate and the toothed block also remains stationary. Therefore, the setting of the transmission assembly enables the rotating ring to rotate in only one direction, thus avoiding the interference between the toothed block and the bearing plate caused by the two-way rotation of the rotating ring.

[0022] Optionally, the power assembly includes a driving gear and a driven gear. The driving gear is coaxially and fixedly connected to the screw rod. The driven gear is coaxially and fixedly connected to the connecting rod. The driving gear and the driven gear mesh with each other.

[0023] By adopting the above technical solution, when the screw rod rotates, it can drive the connecting rod to rotate through the driving gear and the driven gear, with a simple structure, stable and reliable.

[0024] Optionally, an elastic pad for abutting against the bottom wall of the bearing plate is fixedly connected to the top end of the tooth block.

[0025] By adopting the above technical solution, the setting of the elastic pad can enhance the vibration amplitude caused by the knocking of the tooth block on the bearing plate, thereby enhancing the vibration effect; in addition, the setting of the elastic pad can also protect the bearing plate, which helps to ensure the service life of the bearing plate.

[0026] To sum up, the present application includes at least one of the following beneficial technical effects:

[0027] 1. During the working process of the device, the movable part of the power telescopic member extends and retracts repeatedly, causing the placement rack to swing back and forth. Therefore, during the heating process of the vaccine bag, the vaccine bag can also swing back and forth, and the liquid in the vaccine bag can flow, so that the vaccine bag is heated more fully, which helps to improve the thawing efficiency of the vaccine in the vaccine bag.

[0028] 2. A sliding exhaust pipe is arranged above each bearing plate. The exhaust pipe can discharge hot air downward, and the hot air discharged by the exhaust pipe can be blown to the top of the vaccine bag, so that the vaccine bag is heated more fully, which helps to ensure the melting efficiency of the vaccine.

Detailed implementation manners

[0037] The following further describes the present application in detail in conjunction with the attached Figure 1-7 drawings.

[0038] Embodiment 1

[0039] The embodiment of the present application discloses a seesaw type melting device. Refer to Figure 1 and Figure 2 , the seesaw type melting device includes a cabinet body 1, a placement rack 2, a heating assembly 3 and a power telescopic member 4. The height direction of the cabinet body 1 is vertically arranged, and the placement rack 2 is arranged inside the cabinet body 1; the placement rack 2 is in the shape of a rectangular frame, the middle part of the placement rack 2 is hinged to the inner wall of the cabinet body 1, and the hinge axis of the placement rack 2 is horizontally arranged. The heating assembly 3 is arranged on the placement rack 2 and can heat the vaccine bags placed on the placement rack 2. The power telescopic member 4 is a servo electric cylinder, and the power telescopic member 4 includes a fixed part 41 and a movable part 42, and one end of the movable part 42 is slidably arranged in the fixed part 41. The fixed part 41 is hinged to the inner wall of the cabinet body 1, and the hinge axis is parallel to the rotation axis of the placement rack 2; the movable part 42 is hinged to the side wall at the top of the placement rack 2, and the hinge axis is parallel to the rotation axis of the placement rack 2. Therefore, when the movable part 42 of the power telescopic member 4 extends first, then retracts, and then reciprocates in this way, the placement rack 2 can be swung back and forth, so that the vaccine bags on the placement rack 2 can swing during the heating process, thereby enhancing the melting efficiency of the vaccine in the vaccine bags. In this embodiment, the placement rack 2 can swing back and forth by 10-12°, and the swing speed is adjustable.

[0040] Refer to Figure 2 and Figure 3, the placement rack 2 includes two side plates 21 arranged in parallel at intervals, and the two side plates 21 are fixedly connected between them. A bearing plate 5 is arranged between the two side plates 21. There are multiple groups of bearing plates 5, and they are evenly spaced along the height direction of the side plates 21. Each group of bearing plates 5 includes two symmetrically arranged ones, and these two bearing plates 5 are respectively fixedly connected to the inner walls of the two side plates 21. The top surface of each group of bearing plates 5 can be used to place a vaccine bag, and the volume of the vaccine bag is 10L or 20L. During use, place the vaccine bag in the tooling, and then fixedly install the tooling on the top surface of the bearing plate 5 to complete the placement of the vaccine bag; the tooling can limit the position of the vaccine bag to prevent the vaccine bag from falling off during the rotation of the placement rack 2.

[0041] Among them, a plurality of ventilation holes 51 are opened on the bearing plate 5, so that the bottom of the vaccine bag can also be fully heated, which helps to ensure the melting rate.

[0042] Refer to Figure 1 , a protective door 6 is hinged on one side of the cabinet body 1, and an observation window 61 made of transparent glass is arranged on the protective door 6, so that it is convenient to observe the melting situation inside the cabinet body 1.

[0043] Refer to Figure 2 and Figure 3 , there are multiple groups of heating components 3, and they are spaced along the height direction of the placement rack 2; each group of heating components 3 corresponds to a group of bearing plates 5. The heating component 3 includes a mounting seat 31, a blower and a heating element. There are four mounting seats 31, and two mounting seats 31 are fixedly connected to the outer wall of each side plate 21; the blower is fixedly connected in the mounting seat 31, and the air outlet side of the blower faces the inside of the placement rack 2; the heating element is a heating wire, and the heating element is fixedly connected to the mounting seat 31, and the heating element is located on the air outlet side of the blower. Therefore, the heating wire can heat the air blown out by the blower, so as to blow hot air into the placement rack 2 to heat the vaccine bag located on the placement rack 2, thereby accelerating the melting of the vaccine. Since there are multiple groups of heating components 3, the heating degree of each group of heating components 3 can be controlled as needed, so as to achieve zoning control and stronger applicability.

[0044] The implementation principle of Embodiment 1 is: put the vaccine bag into the tooling, and then fixedly install the tooling on the top wall of the bearing plate 5. Then close the protective door 6, and then the blower blows hot air into the placement rack 2 under the action of the heating element to accelerate the melting of the vaccine in the vaccine bag. At the same time, the movable part 42 of the power telescopic part 4 makes an alternating action of extending and retracting, so that the placement rack 2 swings back and forth. Therefore, the vaccine bag on the placement rack 2 can swing accordingly, and the vaccine bag can contact the hot air more fully, and the liquid in the vaccine bag can also flow, avoiding accumulation in a certain place, thereby improving the melting efficiency of the vaccine.

[0045] Embodiment 2

[0046] Reference Figure 4 Differing from Embodiment 1, in this embodiment, a blowing assembly 7 is provided on the placement rack 2. The blowing assembly 7 includes an exhaust pipe 71 and a hose 72. A plurality of exhaust pipes 71 are provided, and the number of exhaust pipes 71 is the same as the number of groups of the bearing plates 5. Each group of bearing plates 5 corresponds to one exhaust pipe 71. The exhaust pipe 71 is located inside the placement rack 2, above the corresponding bearing plate 5, and the rotation axes of the exhaust pipe 71 and the placement rack 2 are parallel. A plurality of exhaust ports 711 are provided on the bottom wall of the exhaust pipe 71 along its length direction, and the exhaust ports 711 face the bearing plate 5. Both ends of the exhaust pipe 71 are closed. One end of the hose 72 is fixedly connected to and communicates with the exhaust pipe 71; one end of the hose 72 away from the exhaust pipe 71 is fixedly connected with a diversion frame 721, and one end of the diversion frame 721 away from the hose 72 is located at the air outlet of the fan. The length of the hose 72 is relatively long, so that the exhaust pipe 71 can always maintain connection with the hose 72 during the sliding process.

[0047] Therefore, a part of the hot air blown out by the fan can flow into the exhaust pipe 71 through the diversion frame 721 and the hose 72, and then be discharged downward from the exhaust ports 711 on the exhaust pipe 71 and blown to the top of the vaccine bag, thereby expanding the contact area between the hot air and the vaccine bag and helping to accelerate the dissolution of the vaccine.

[0048] Reference Figure 4 and Figure 5 Further, sliding grooves 211 are formed in both side plates 21 along their width directions, and both ends of the exhaust pipe 71 pass through the two sliding grooves 211 respectively, so the exhaust pipe 71 is slidably arranged; a driving assembly 8 for driving the exhaust pipe 71 to slide back and forth is further provided on the placement rack 2. The number of driving assemblies 8 is the same as the number of exhaust pipes 71, and each driving assembly 8 is used to drive the corresponding exhaust pipe 71 to slide back and forth.

[0049] The driving assembly 8 includes a support rod 81, a rotary power member 82, a screw rod 83, and a guide rod 84. There are two support rods 81, and the two support rods 81 are respectively fixedly connected to the outer walls of the ends of the exhaust pipe 71 passing through the sliding groove 211. The support rods 81 are arranged along the height direction of the placement rack 2. The guide rod 84 and the screw rod 83 are respectively arranged on one side of the two side plates 21 away from each other. The guide rod 84 and the screw rod 83 are both parallel to the width direction of the side plate 21. The guide rod 84 is fixedly connected to the outer wall of the side plate 21, and the screw rod 83 is rotatably arranged on the outer wall of the side plate 21 around its own axis. A through hole is formed in one of the support rods 81, and the guide rod 84 is slidably inserted into the through hole. A threaded hole is provided in the other support rod 81, and the threaded hole is threadedly connected to the screw rod 83. The rotary power member 82 is a motor, and the rotary power member 82 is fixedly connected to the outer wall of one of the side plates 21 by bolts. The output shaft of the rotary power member 82 is coaxially fixedly connected to the screw rod 83. Therefore, after the rotary power member 82 is started, it can drive the screw rod 83 to rotate, the screw rod 83 drives the support rod 81 to slide, and the support rod 81 drives the exhaust pipe 71 to slide. By rotating the output shaft of the rotary power member 82 forward and backward, the exhaust pipe 71 can reciprocally slide, thereby increasing the contact area between the hot air blown out by the exhaust pipe 71 and the vaccine bags.

[0050] Referring to Figure 5 , Figure 6 and Figure 7 , a vibration mechanism 9 is further provided on the placement rack 2. There are multiple groups of vibration mechanisms 9, and the number of vibration mechanisms 9 is the same as the number of driving assemblies 8. Each vibration mechanism 9 corresponds to a driving assembly 8. The vibration mechanism 9 is arranged on the outside of the placement rack 2, and the vibration mechanism 9 is located on the side close to the screw rod 83. The vibration mechanism 9 includes a connecting rod 91, a rotating ring 92, a tooth block 93, a first elastic member 94, a transmission assembly 95, and a power assembly 96. The connecting rod 91 is parallel to the screw rod 83, and the connecting rod 91 is rotatably arranged on the outer wall of the side plate 21 around its own axis. The rotating ring 92 is a circular ring, and the rotating ring 92 is coaxially sleeved outside the connecting rod 91. There are multiple rotating rings 92, and they are evenly spaced along the length direction of the connecting rod 91. Limiting plates 10 are fixedly connected to both sides of the rotating ring 92 on the outer wall of the connecting rod 91, and an arc-shaped limiting block 101 is fixedly connected to the end of the limiting plate 10. Correspondingly, annular limiting grooves 921 are coaxially formed on both sides of the rotating ring 92, and the limiting block 101 is slidably clamped in the corresponding limiting groove 921, so that the rotating ring 92 is rotatably connected to the connecting rod 91.

[0051] There are multiple tooth blocks 93, and the number of tooth blocks 93 is the same as the number of rotating rings 92. Each tooth block 93 corresponds to a rotating ring 92. The tooth block 93 is slidably arranged on the outer wall of the side plate 21 along the height direction of the side plate 21. The rotating ring 92 is located on the side of the tooth block 93 away from the side plate 21, and a section of tooth teeth for meshing with the tooth block 93 is provided on the outer wall of the rotating ring 92. Therefore, the rotation of the rotating ring 92 can cause the tooth block 93 to intermittently move downward.

[0052] On the outer side of the bearing plate 5 close to one side of the screw 83, a support plate 11 is fixedly connected, and one end of the support plate 11 passes through the side plate 21. The number of the support plates 11 is the same as the number of the rotating rings 92. Each support plate 11 corresponds to a rotating ring 92, and the support plate 11 is located above the corresponding rotating ring 92.

[0053] Referring to Figure 7 , the number of the first elastic members 94 is the same as the number of the tooth blocks 93. Each first elastic member 94 corresponds to a tooth block 93. The first elastic member 94 is a spring, and the first elastic member 94 is fixedly connected between the bottom wall of the tooth block 93 and the side plate 21. Under normal state, the first elastic member 94 makes the top wall of the tooth block 93 abut against the bottom wall of the support plate 11.

[0054] Referring to Figure 7 , the number of the transmission assemblies 95 is the same as the number of the rotating rings 92. Each transmission assembly 95 corresponds to a rotating ring 92. The transmission assembly 95 includes a ratchet wheel 951, a pawl 952 and a second elastic member 953. The ratchet wheel 951 is coaxially and fixedly connected to the connecting rod 91. The pawl 952 is hinged to the inner wall of the rotating ring 92, and the hinge axis of the pawl 952 is parallel to the axis of the rotating ring 92. A plurality of pawls 952 are arranged in a circumferential array. The number of the second elastic members 953 is the same as the number of the pawls 952. Each second elastic member 953 corresponds to a pawl 952. The second elastic member 953 is a torsion spring, and the second elastic member 953 is fixedly connected between the pawl 952 and the inner wall of the rotating ring 92. The second elastic member 953 makes the pawl 952 abut tightly against the ratchet wheel 951.

[0055] Therefore, when the connecting rod 91 rotates forward, the connecting rod 91 drives the ratchet wheel 951 to rotate. The pawl 952 abuts tightly against the ratchet wheel 951. Therefore, when the connecting rod 91 rotates, it can drive the rotating ring 92 to rotate in the same direction. When the teeth on the rotating ring 92 are engaged with the tooth block 93, the rotation of the rotating ring 92 can drive the tooth block 93 to move downward. After the teeth on the rotating ring 92 are disengaged from the tooth block 93, the first elastic member 94 makes the tooth block 93 move upward and makes the top end of the tooth block 93 abut against the bottom wall of the support plate 11. The first elastic member 94 makes the upward movement speed of the tooth block 93 faster. Therefore, when the tooth block 93 abuts against the support plate 11, it can strike the support plate 11, so that the support plate 11 vibrates. Since the support plate 11 is fixedly connected to the bearing plate 5, the strike caused by the tooth block 93 can make the bearing plate 5 vibrate, thereby driving the vaccine bag to vibrate, which helps to accelerate the melting of the vaccine in the vaccine bag.

[0056] When the connecting rod 91 rotates in the reverse direction, the connecting rod 91 drives the ratchet wheel 951 to rotate. At this time, the ratchet pawl 952 can rotate and avoid, so the rotating ring 92 can remain stationary at this time, so that the tooth block 93 remains stationary; therefore, the reverse rotation of the connecting rod 91 will not drive the tooth block 93 to move upward, resulting in interference between the tooth block 93 and the support plate 11 and affecting the normal rotation of the connecting rod 91.

[0057] Referring to Figure 5 , the power assembly 96 includes a driving gear 961 and a driven gear 962. The driving gear 961 is coaxially and fixedly connected to the screw rod 83, the driven gear 962 is coaxially and fixedly connected to the connecting rod 91, and the driving gear 961 and the driven gear 962 are meshed with each other. Therefore, when the rotary power member 82 drives the screw rod 83 to rotate, the screw rod 83 drives the driving gear 961 to rotate, the driving gear 961 drives the driven gear 962 to rotate, and the driven gear 962 drives the connecting rod 91 to rotate; the rotation of the connecting rod 91 does not require an additional power source, so it is more energy-saving.

[0058] An elastic pad 931 is fixedly bonded to the top end of the tooth block 93. The elastic pad 931 is made of rubber. Therefore, when the tooth block 93 moves upward and strikes the support plate 11, the vibration effect of the support plate 11 and the bearing plate 5 can be enhanced.

[0059] Furthermore, a connecting plate 12 is fixedly connected between the two bearing plates 5 of each group. Therefore, the connecting plate 12 connects the two bearing plates 5 together. When one bearing plate 5 vibrates, it can drive the other bearing plate 5 to vibrate, thereby enhancing the vibration effect on the vaccine bag.

[0060] The implementation principle of Embodiment 2 is as follows: When the movable part 42 of the power telescopic member 4 expands and contracts, the placement rack 2 swings, and at the same time, the output shaft of the rotary power member 82 rotates forward and reverses alternately. When the output shaft of the rotary power member 82 rotates, it can drive the screw rod 83 to rotate. The rotation of the screw rod 83 causes the support rod 81 to slide, and the support rod 81 drives the exhaust pipe 71 to slide. The exhaust pipe 71 can blow hot air to the top of the vaccine bag, thereby expanding the contact area between the hot air and the vaccine bag and helping to accelerate the melting of the vaccine.

[0061] With the cooperation of the driving gear 961 and the driven gear 962, the screw rod 83 can drive the connecting rod 91 to rotate while rotating. When the connecting rod 91 rotates, it drives the rotating ring 92 to rotate; when the teeth on the rotating ring 92 are engaged with the tooth block 93, the rotation of the rotating ring 92 can cause the tooth block 93 to move downward; when the teeth on the rotating ring 92 disengage from the tooth block 93, the first elastic member 94 causes the tooth block 93 to move upward. The elastic pad 931 at the top of the upward-moving tooth block 93 can strike the bottom wall of the support plate 11, causing the support plate 11 and the bearing plate 5 to vibrate, so that the vaccine bag placed on the bearing plate 5 vibrates, which helps to further accelerate the melting of the vaccine.

[0062] The above are optional embodiments of the present application, and do not limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
