[0057] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0058] Based on the problem that the rotary drive and lifting drive structures in the water bath device occupy a relatively large space, the present application provides a water bath device. By arranging a bearing assembly slidably connected to the output end of the rotary drive member and a switching mechanism, it is realized that only the rotary drive member can simultaneously drive the bearing assembly to rotate and lift, drive the reagent bottle to rotate and lift, simplify the rotary drive and lifting drive structures in the water bath device, and effectively reduce the space occupied by the rotary drive and lifting drive structures in the water bath device; for specific details, refer to the following embodiments.

[0059] Please refer to Figures 1 to 5 , in the first embodiment of the present application, a water bath device 10 is provided, which can be applied to quickly thaw vaccines. The vaccines can be applied to humans, poultry, livestock or other animals, and the specific application objects are not limited. The water bath device 10 heats the reagent bottle by means of a water bath, and has a fast thawing effect on the vaccines stored in the reagent bottle.

[0060] The water bath device 10 includes a frame 11, a rotary drive member 12, a bearing assembly 13 and a switching mechanism 14. The frame 11 has the functions of carrying and protecting each component, and can adopt structures such as a frame, a support base and a protective shell. The rotary drive member 12 is installed on the frame 11 and has the function of driving the reagent bottle to rotate in the water bath to promote the rapid thawing of the vaccines in the reagent bottle. The bearing assembly 13 has the effects of carrying and accommodating the reagent bottle; the bearing assembly 13 is slidably connected to the output end 121 of the rotary drive member 12 and rotates around the axis of the output end 121 under the drive of the output end 121 of the rotary drive member 12, so that the bearing assembly 13 can slide relative to the rotation axis of the output end 121, and realize heating the vaccines in a constant temperature water bath to promote the rapid thawing of the vaccines.

[0061] The switching mechanism 14 is installed on the frame 11, and the switching mechanism 14 has the function of switching the motion form of the bearing assembly 13. The switching mechanism 14 includes a rotary member 141, and the rotary member 141 is sleeved on the bearing assembly 13 and is in screw fit with the bearing assembly 13; the screw fit can be in the form of a screw and a nut; through the screw fit between the rotary member 141 and the bearing assembly 13, the bearing assembly 13 can rotate relative to the rotary member 141 and move axially along the rotation axis at the same time, that is, perform screw-up or screw-down motion, and different rotation directions of the bearing assembly 13 correspond to moving along both ends of the rotation axis, thereby realizing the lifting of the bearing assembly 13.

[0062] The rotating member 141 can be switched between a movable state and a fixed state relative to the frame 11. In the movable state, the rotating member 141 can rotate relative to the frame 11. At this time, the rotating member 141 can rotate together with the bearing assembly 13 under the rotational drive of the rotational drive member 12, and the bearing assembly 13 has no lifting action. In the fixed state, the rotating member 141 is relatively fixed to the frame 11 and cannot rotate. At this time, under the rotational drive of the rotational drive member 12, relative movement occurs between the rotating member 141 and the bearing assembly 13. Since the rotating member 141 is sleeved on the bearing assembly 13 and is in screw fit with the bearing assembly 13, the bearing assembly 13 slides along the rotational axis of the output end 121 to helically rise or helically descend relative to the rotating member 141, so as to realize the rising or falling of the carried reagent bottle. After the bearing assembly 13 carries the reagent bottle and rises, the reagent bottle is separated from the water bath medium, which is convenient for the user to pick up and place the reagent bottle on the bearing assembly 13, improving the use convenience. After the bearing assembly 13 carries the reagent bottle and rises, the reagent bottle is immersed in the water bath medium to realize heating and thawing of the vaccine.

[0063] The rotating member 141 can be installed on the frame 11 through a thrust bearing, which helps to improve the smoothness and reliability of the rotation of the rotating member 141. Thrust bearings are respectively arranged on both sides of the rotating member 141 to reduce the friction between the rotating member 141 and the frame 11 when the rotating member 141 is in the movable state, and ensure the smoothness of the rotation process of the rotating member 141.

[0064] By arranging the bearing assembly 13 to be slidably connected to the output end 121 of the rotational drive member 12 and arranging the switching mechanism 14, it is realized that only through the rotational drive member 12, the bearing assembly 13 can be simultaneously driven to rotate and lift, driving the reagent bottle to rotate and lift, simplifying the rotational drive and lifting drive structures in the water bath device 10, effectively reducing the space occupied by the rotational drive and lifting drive structures in the water bath device 10, facilitating the installation and component repair and replacement of the water bath device 10, and effectively reducing the equipment manufacturing cost. At the same time, compared with the form of separately driving rotation and lifting, only through the rotational drive member 12, the bearing assembly 13 can be simultaneously driven to rotate and lift, effectively improving the operation efficiency and maintenance convenience of the water bath device 10.

[0065] The rotational drive member 12 can adopt a motor or a combination of a motor and a speed reducer, and the output end 121 is located on the motor output shaft or the speed reducer output shaft. The rotational drive member 12 can also adopt a hydraulic motor or other structures that can output rotational driving force.

[0066] Please continue to refer to Figure 2 、 Figure 3 and Figure 5, in some embodiments, the sliding connection between the output end 121 of the rotary driving member 12 and the bearing assembly 13 can be achieved by the cooperation of the limiting shaft 15 and the sliding groove 16. Specifically: among the output end 121 and the bearing assembly 13, one is provided with the limiting shaft 15 and the other is provided with the sliding groove 16; if the output end 121 is provided with the limiting shaft 15, the bearing assembly 13 is correspondingly provided with the sliding groove 16, and at least part of the bearing assembly 13 is sleeved on the output end 121; if the output end 121 is provided with the sliding groove 16, the bearing assembly 13 is correspondingly provided with the limiting shaft 15, and at least part of the output end 121 is sleeved on the bearing assembly 13; the limiting shaft 15 is slidably inserted into the sliding groove 16. By adopting the cooperation structure of the limiting shaft 15 and the sliding groove 16, a rotation limit around the axis is formed between the output end 121 and the bearing assembly 13, so that the output end 121 of the rotary driving member 12 can transmit the driving force to the bearing assembly 13 to drive the bearing assembly 13 to rotate axially around the output end 121. At the same time, it can provide guiding constraints for the lifting process of the bearing assembly 13, ensuring that the bearing assembly 13 can stably slide along the axis of the output end 121 when the rotating member 141 is in a fixed state, and ensuring the normal progress of the lifting movement of the bearing assembly 13.

[0067] Please continue to refer to Figure 3 and Figure 5 , further, the cross-sectional shape of the limiting shaft 15 is designed as a polygon, an ellipse, a slotted circle or other shapes that can achieve the rotation limit between the bearing assembly 13 and the output end 121, such as a spline shape. The sliding groove 16 is slidably matched with the limiting shaft 15, and the cross-sectional shape is the same as that of the limiting shaft 15. Among them, the polygon includes shapes surrounded by multiple straight sides such as triangles, quadrilaterals, pentagons, hexagons, etc.; the slotted circle refers to the cross-sectional shape of the structure formed by opening a key groove or a stepped groove along the axial direction on the surface of the circular shaft, including shapes surrounded by an arc and a single straight side, or multiple straight sides. By adopting the above non-circular cross-sectional shape, it can effectively prevent the limiting shaft 15 from rotating in the sliding groove 16, ensure the formation of a rotation limit between the bearing assembly 13 and the output end 121 of the rotary driving member 12, ensure that the bearing assembly 13 does not deviate when the output end 121 drives the bearing assembly 13 to rotate, maintain the stability of the rotational movement of the bearing assembly 13, and further ensure the stable and orderly progress of the water bath heating of the reagent bottle.

[0068] Taking the hexagonal cross-section of the limit shaft 15 as an example, the limit shaft 15 is a hexagonal prism structure. Each circumferential surface of the limit shaft 15 is in sliding fit with the inner wall of the chute 16, restricting the circumferential rotation of the limit shaft 15, so that the bearing assembly 13 can only slide along the direction of the chute 16, further improving the stability and reliability of the operation of the water bath device 10. If the limit shaft 15 is located at the output end 121 of the rotary drive member 12, the limit shaft 15 can be fixed to the output shaft of the reducer through a bushing. A chute 16 is opened at the bottom end of the bearing assembly 13, and the limit shaft 15 is slidably inserted into the chute 16, effectively ensuring that the bearing assembly 13 rotates under the action of the rotary drive member 12, and rises or falls under the action of the rotating member 141 in the switching mechanism 14.

[0069] Please continue to refer to Figures 2 to 5 In some embodiments, the rotating member 141 is provided with a limiting portion 1411; the switching mechanism 14 further includes a latch member 142, and the latch member 142 is used to fix the rotating member 141 to the frame 11 after cooperating with the limiting portion 1411. The latch member 142 is installed on the frame 11, and the latch member 142 has a locking tongue 1421 that drives and expands and contracts. After the locking tongue 1421 is driven, it expands and contracts to abut against the limiting portion 1411, thereby braking the rotation of the rotating member 141 and realizing the switching of the rotating member 141 between the active state and the fixed state relative to the frame 11. When the latch member 142 drives the locking tongue 1421 to extend and abut against the limiting portion 1411, the rotating member 141 is locked and in a fixed state; when the latch member 142 drives the locking tongue 1421 to retract, the abutment against the limiting portion 1411 is released, and the rotating member 141 can rotate relative to the frame 11 together with the output end 121 of the rotary drive member 12 and is in an active state, so that the rotary drive and the lifting drive are integrated into a single transmission structure, avoiding the additional setting of a lifting drive mechanism, significantly optimizing the spatial layout, and effectively reducing the manufacturing cost of the equipment.

[0070] Please refer to Figures 2 to 6 Furthermore, there are various cooperation forms between the limiting portion 1411 and the locking tongue 1421: one is that the limiting portion 1411 is a limiting tooth 1412, and the limiting teeth 1412 are distributed on the outer circumference of the rotating member 141, which can be a continuous tooth-shaped structure; the latch member 142 drives the locking tongue 1421 to extend or contract. When the locking tongue 1421 extends and abuts against the surface of the limiting tooth 1412, the rotation of the rotating member 141 is restricted; the telescopic direction of the locking tongue 1421 can be the rotation axis of the rotating member 141 or perpendicular to the rotation axis of the rotating member 141; the other is that the limiting portion 1411 is a limiting hole, and there can be multiple limiting holes, and the multiple limiting holes are arranged around the axis of the rotating member 141; the latch member 142 drives the locking tongue 1421 to extend or contract. When the locking tongue 1421 extends and is inserted into the limiting hole, the locking tongue 1421 abuts against the inner wall of the limiting hole, also playing a role in braking the rotating member 141.

[0071] The latch 142 can be one of the following: a push-pull electromagnet, an electric push rod, a piston-type air cylinder, or a piston-type hydraulic cylinder. The push-pull electromagnet controls the extension and retraction of the locking tongue 1421 through electromagnetic force, with a fast response speed and facilitating automated control. At the same time, when the locking tongue 1421 is not aligned with the limit teeth 1412 or extends out of the limit hole, the locking tongue 1421 is blocked by the end face or circumferential surface of the rotating member 141 and cannot extend in place. The resistance generated by the electromagnetic force is small, preventing the locking tongue 1421 from damaging the rotating member 141. The electric push rod drives the push rod to extend and retract through a motor. The push rod can be used as the locking tongue 1421 to abut against the limit portion 1411, featuring a simple structure and a large thrust. The piston-type air cylinder and the piston-type hydraulic cylinder respectively utilize the pressure of compressed gas and hydraulic oil to drive the piston to move. The piston can be used as the locking tongue 1421, which can adapt to different working environments and load requirements.

[0072] In some embodiments, the rotating member 141 is provided with a limit portion 1411; the switching mechanism 14 further includes a clamping member (not shown in the figure). The clamping member is used to fix the rotating member 141 to the frame 11 after cooperating with the limit portion 1411. The clamping member is installed on the frame 11 and has a movably clamping end (not shown in the figure). When the clamping member drives the clamping end to clamp the limit portion 1411, the rotation of the rotating member 141 is braked. When the clamping member drives the clamping end to release the limit portion 1411, the rotating member 141 can rotate relative to the frame 11 together with the output end 121 of the rotation driving member 12, integrating the rotation drive and the lifting drive into a single transmission structure, avoiding the additional setting of a lifting drive mechanism and significantly optimizing the spatial layout. When the clamping end clamps the limit portion 1411, the clamping end can be a clamping structure or a brake pad structure, braking the rotation of the rotating member 141 through frictional resistance.

[0073] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 7 and Figure 8In some embodiments, the water bath device 10 is provided with a water bath chamber 171 for accommodating a liquid heating medium (e.g., water) at a preset temperature. The carrying assembly 13 includes a reagent bracket 131 and a transmission member 132. The reagent bracket 131 is located in the water bath chamber 171 and is used to directly carry a reagent bottle. One end of the transmission member 132 is connected to the reagent bracket 131, and the other end is slidably connected to the output end 121, and rotates around the axial direction of the output end 121 under the drive of the output end 121. The rotating member 141 is sleeved on the transmission member 132, and the power of the rotating driving member 12 can be transmitted to the reagent bracket 131 through the transmission member 132, driving the reagent bottle to rotate in the water bath chamber 171. At the same time, the switching mechanism 14 acts on the transmission member 132 through the rotating member 141, and can realize the lifting and lowering movement of the reagent bracket 131, thereby realizing the rotation and lifting movement of the reagent bottle in the water bath chamber 171, ensuring the rapid thawing of the vaccine, and convenient for users to take and put the reagent bottle. The transmission member 132 may include a connecting shaft 1321 and a transmission shaft 1322 that are separately arranged, one end of the transmission shaft 1322 is connected to the connecting shaft 1321, and the other end is slidably connected to the output end 121; the end of the connecting shaft 1321 that is away from the transmission shaft 1322 is connected to the reagent bracket 131. The connecting shaft 1321 and the transmission shaft 1322 may also be arranged integrally. The transmission shaft 1322 may be a lead screw structure, and the rotating component 141 is correspondingly arranged as a lead screw nut, and the lead screw structure and the lead screw nut are spirally matched.

[0074] Please continue to refer to Figure 1 , Figure 3 , Figure 5 and Figure 7 Furthermore, the water bath device 10 also includes a water bath pot 17. The water bath pot 17 includes a pot body 172 and a water-proof jacket 173. The pot body 172 is installed on the frame 11 to accommodate and support. The water-proof jacket 173 is located inside the pot body 172, and the bottom end of the water-proof jacket 173 is connected to the pot body 172. The outer peripheral surface of the water-proof jacket 173 and the pot body 172 are surrounded to form a water bath cavity 171 for accommodating a liquid heating medium at a preset temperature. The water-proof jacket 173 is provided with a water-proof channel 174 that passes through the bottom end of the pot body 172. At least part of the transmission member 132 is provided with the water-proof channel 174 and is connected to the reagent bracket 131, so that the transmission member 132 can pass through the water-proof jacket 173 to transmit the power of the rotating drive member 12 to the reagent bracket 131 in the water bath chamber 171, while preventing the liquid heating medium such as water in the water bath chamber 171 from corroding the transmission member 132, thereby extending the service life of the water bath device 10. The bottom end of the water-proof jacket 173 is sealed with the pot body 172, and a sealant or a sealing gasket can be used to seal the connection; or the water-proof jacket 173 and the pot body 172 are integrally arranged, for example, integrally manufactured or the bottom end of the water-proof jacket 173 and the pot body 172 are seamlessly welded to prevent the liquid heating medium such as water in the water bath chamber 171 from leaking into the water-proof channel 174 and corroding the transmission member 132.

[0075] The reagent bracket 131 includes a sleeve portion 1311 and a supporting portion 1312. The bottom end of the sleeve portion 1311 is connected to the supporting portion 1312. The sleeve portion 1311 is cylindrical and sleeved on the outer periphery of the water isolation sleeve 173, which helps to separate the liquid heating medium from the transmission member 132. The supporting portion 1312 has a plurality of accommodating slots 1313 for accommodating reagent bottles. The transmission member 132 can be threadedly connected to the top end of the sleeve portion 1311, which is convenient for disassembly, assembly and maintenance.

[0076] Please refer to Figure 5 and Figure 9 Further, the water bath device 10 further includes a seal 18. The seal 18 is clamped between the outer periphery of the water isolation sleeve 173 and the reagent bracket 131, and is specifically sealed and connected between the water isolation sleeve 173 and the sleeve portion 1311 to seal the gap between the water isolation sleeve 173 and the reagent bracket 131, so as to prevent the liquid heating medium from being driven by the reagent bracket 131 to rotate into the water isolation sleeve 173 during rotation, avoid corrosion of the transmission member 132, and effectively extend the service life of the water bath device 10.

[0077] Please continue to refer to Figure 1 、 Figure 3 and Figure 5 In some embodiments, the water bath device 10 further includes a first limit switch 191 and / or a second limit switch 192. Both the first limit switch 191 and the second limit switch 192 are installed on the frame 11 and electrically connected to the rotation driving member 12 or the switching mechanism 14. The first limit switch 191 is configured to be triggered when the carrying component 13 rises to a first preset position, so that the rotation driving member 12 stops rotating or the rotating component 141 in the switching mechanism 14 is switched to an active state, preventing the carrying component 13 from rising excessively. The first preset position is a suitable position for the user to place and remove reagent bottles on the carrying component 13, which is determined by the installation position of the first limit switch 191. The second limit switch 192 is configured to be triggered when the carrying component 13 descends to a second preset position, so that the rotation driving member 12 stops rotating or the rotating component 141 in the switching mechanism 14 is switched to an active state, preventing the carrying component 13 from descending excessively. The second preset position is the appropriate depth at which the reagent bottle is immersed in the liquid heating medium in the water bath chamber 171, which is determined by the installation position of the second limit switch 192. By setting the first limit switch 191 and the second limit switch 192, the lifting position of the carrying component 13 can be accurately controlled, ensuring the safe operation of the water bath device 10 and improving the automation degree of the operation of the water bath device 10 at the same time.

[0078] Please refer to Figure 1 and Figure 10, Further, the water bath device 10 further includes a controller 193, which is electrically connected to the rotation driving member 12, the first limit switch 191 and the second limit switch 192, and is used to control the rotation and lifting process of the carrying component 13. Specifically, it can be: after starting, control the rotation driving member 12 to rotate forward, and after driving the carrying component 13 to rotate for a preset time, control the latch member 142 or the clamping member in the switching mechanism 14 to act, so that the locking tongue 1421 or the clamping end acts on the limiting portion 1411 of the rotating member 141 to brake the rotation of the rotating member 141. At this time, relative movement occurs between the carrying component 13 and the rotating member 141 to achieve spiral rising until the first limit switch 191 is triggered, and then control the rotation driving member 12 to stop acting. The user can place and remove reagent bottles on the carrying component 13;

[0079] After the next start, control the rotation driving member 12 to rotate reversely. At this time, the locking tongue 1421 or the clamping end keeps braking the rotation of the rotating member 141, and relative movement occurs between the carrying component 13 and the rotating member 141 to achieve spiral descending until the second limit switch 192 is triggered, and then control the latch member 142 or the clamping member in the switching mechanism 14 to act, so that the locking tongue 1421 or the clamping end acts on the limiting portion 1411 of the rotating member 141 to release the braking of the rotation of the rotating member 141; then, after the carrying component 13 rotates for a preset time, control the latch member 142 or the clamping member in the switching mechanism 14 to act, so that the locking tongue 1421 or the clamping end acts on the limiting portion 1411 of the rotating member 141 to brake the rotation of the rotating member 141. At this time, relative movement occurs between the carrying component 13 and the rotating member 141 to achieve spiral rising until the first limit switch 191 is triggered, and then control the rotation driving member 12 to stop acting. The user can place and remove reagent bottles on the carrying component 13; wait for the next start.
