[0026] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] The present embodiment provides a contrast agent water brewing device, which is mainly used to solve the problem that when brewing contrast agent, the user needs to hold the cup body to stir, and under the action of high-temperature hot water, the surface of the cup is relatively hot, and the user often cannot stand the high temperature, and provides the following technical solutions. Figure 1-Figure 6 Make a detailed description:

[0028] Embodiment 1:

[0029] A contrast agent water-adding brewing device combined with a disposable cup includes a placement bin 1 with two clamping assemblies 2 arranged on the top. When in use, the user places the cup with contrast agent particles inside on the top of the placement bin 1, and controls the two clamping units 3 to clamp the cup, so as to limit the position of the cup in the placement bin 1, thereby facilitating subsequent stirring operations. The main components of the two clamping assemblies 2 are: two fixed bins 21 that are fixedly mounted on the surface of the placement bin 1, and one end of the two fixed bins 21 is provided with an annular edge 22. During operation, the cup is placed between the two annular edges 22, and the inner walls of the two fixed bins 21 are fixedly mounted with water bags 23, and the surfaces of the two water bags 23 are fixedly mounted with bellows 24, and the other ends of the two bellows 24 are fixedly mounted with drive plates 25. In actual use, the user controls the two drive plates 25 to move away from or close to each other through the control unit 3, and can squeeze the water bag 23 to achieve the setting. The cup is clamped between the two water bags 23. When the cup body is large, the cup body can further squeeze the bellows 24 by squeezing the water bag 23, so that the cup is effectively limited by squeezing the water bag 23. The main components of the control unit 3 are: a control board 31 fixedly mounted on the surface of the placement bin 1, and a driving disk 32 is rotatably plugged into the top of the control board 31. When in use, the user rotates the driving disk 32, and the movement trend of the driving disk 32 is transmitted to the two driving plates 25 through the first driving unit, so that the two driving plates 25 move away from or close to each other, thereby realizing the control of the two driving plates 25.

[0030] By arranging two clamping assemblies 2 above the placement bin 1, when in use, the user can first pour the contrast agent into the interior of the cup, and then place the cup between the two clamping assemblies 2, and control the two clamping assemblies 2 to cooperate through the control unit 3 to clamp the cup. At this time, pour hot water into the interior of the cup, and stir without holding the cup, thereby improving the user's comfort during the stirring process.

[0031] The main components of the first transmission unit 33 are: a swing plate 331 rotatably plugged into the surface of the control plate 31, and transmission plates 332 are rotatably installed at both ends of the swing plate 331, and sliders 334 are rotatably installed at the other ends of the two transmission plates 332, and a plurality of driving grooves 333 are opened on the surface of the control plate 31, and the surfaces of the two sliders 334 are respectively slidably plugged into the inner walls of the plurality of driving grooves 333 and are respectively fixedly installed on the surfaces of the two driving plates 25. When in use, the user transmits the movement trend of the driving disk 32 to the swing plate 331 through the second transmission unit 335, thereby driving the swing plate 331 to rotate, further driving the two transmission plates 332 to swing, and driving the two sliders 334 to slide on the inner walls of the plurality of driving grooves 333, thereby driving the two driving plates 25 respectively fixedly installed on the surfaces of the two sliders 334 to approach or move away at the same time.

[0032] The main components of the second transmission unit 335 are: a mounting plate 3351 fixedly mounted on the surface of the control panel 31, and a first transmission rod 3352 is rotatably plugged on the surface of the mounting plate 3351, and a transmission wheel 3353 is fixedly mounted on one end of the first transmission rod 3352, and the transmission wheel 3353 and the driving disk 32 are connected to each other through a transmission belt 3354. In subsequent use, the user rotates the driving disk 32 to drive the transmission wheel 3353 to rotate, and the rotation of the transmission wheel 3353 can drive the first transmission rod 3352 to rotate, and the other end of the first transmission rod 3352 is fixedly mounted on the driving disk 32 to drive the transmission wheel 3353 to rotate. One end is rotatably plugged into the surface of the control board 31 and the surface of the swing plate 331 are fixedly installed with a first bevel gear 3355 (one of the two first bevel gears 3355 is fixedly sleeved on the surface of the first transmission rod 3352, and the other is fixedly installed at one end of the swing plate 331). Because the two first bevel gears 3355 are meshed with each other, when the user rotates the drive disk 32, the transmission wheel 3353 and the swing plate 331 can be driven to swing through belt transmission and gear transmission in turn. When the swing plate 331 swings 90 degrees, the two drive plates 25 can be fully driven to move closer to and away from each other.

[0033] Embodiment 2:

[0034] The second embodiment of the present application is to further improve the present application based on the first embodiment. Figures 1 to 6A negative pressure bin 8 is fixedly mounted on the surface of the control panel 31, and a negative pressure plate 9 is slidably inserted into the inner wall of the negative pressure bin 8. At the same time, a water pressure tank 4 is provided on the top of the placement bin 1 (in actual use, there is water inside the placement bin 1 and the water pressure tank 4), and a first water trough 5 is provided between the water pressure tank 4 and the inner wall of the placement bin 1. In actual use, after the user rotates the driving disk 32 to drive one of the first bevel gears 3355 to rotate, under the action of the third transmission unit 10, the negative pressure plate 9 and the water pressure plate 6 provided on the inner wall of the water pressure tank 4 will slide in opposite directions, thereby, through the downward pressure of the water pressure plate 6, the water inside the placement bin 1 is driven to flow into the inner walls of the two water bags 23 through a plurality of second water troughs 7 respectively provided on the surfaces of the two fixed bins 21 and the two water bags 23, thereby achieving the purpose of spraying water on the two water bags 23. In the process of water injection, that is, in the process of the two driving plates 25 approaching each other, the interiors of the two water bags 23 are synchronously filled with water, so as to fully clamp the water cup arranged between the two water bags 23, and in this process, the negative pressure plate 9 also slides on the inner wall of the negative pressure bin 8, so that the gas pressure below the negative pressure plate 9 is weakened, and the pressure of the air above can squeeze the negative pressure bin 8, so that it is more firmly fixed on the desktop (its principle is similar to the fixation of sports equipment on the ground in the current prior art). It should be noted that: the negative pressure bin 8 is in the shape of a suction cup and has a circle of rubber edge on the surface, which can ensure the sealing of its bottom, and the top of the negative pressure bin 8 is provided with an air hole, so that in the process of the negative pressure plate 9 moving, the gas above the negative pressure plate 9 can be quickly discharged through the air hole, thereby fixing the negative pressure bin 8 on the desktop.

[0035] The main components of the third transmission unit 10 are: two guide rails 104 fixedly mounted on the surfaces of the placement bin 1 and the negative pressure bin 8, respectively; at the same time, a second bevel gear 101 is meshed on the surface of one of the first bevel gears 3355, and a second transmission rod 102 is fixedly mounted on the surface of the second bevel gear 101, and one end of the second transmission rod 102 is rotatably plugged into the surface of the control panel 31 and a transmission gear 103 is fixedly mounted thereon, and two racks 105 are meshed on the surface of the transmission gear 103, and guide protrusions 106 are provided on the surfaces of the two racks 105, and the two guide protrusions 106 are respectively slidably plugged into the inner walls of the two guide rails 104, and when in use, the user rotates the drive disk 32 to drive the first bevel gear 3355 to rotate. When 55 rotates, the first bevel gear 3355 will drive the transmission gear 103 to rotate, and the transmission gear 103 further drives the two racks 105 to move in opposite directions. Because the two racks 105 are respectively connected to the surfaces of the water pressure plate 6 and the negative pressure plate 9 through two connecting rods 107, and the surface of one of the connecting rods 107 is slidably inserted into the surface of the negative pressure bin 8, the water pressure plate 6 and the negative pressure plate 9 can respectively realize the filling of the two water bags 23 (the principle of water filling is to drive water from the first water trough 5 and the two second water troughs 7 to flow into the interior of the two water bags 23 through the downward pressure of the water pressure plate 6) and the creation of a negative pressure environment inside the negative pressure bin 8. It should be noted that: a piston is threadedly inserted on the surface of the placement bin 1 for filling and draining water.

[0036] By dividing the clamping assembly 2 into a fixed bin 21 fixedly mounted on the surface of the placement bin 1 and a water bag 23 fixedly mounted on the inner wall of the fixed bin 21, the user needs to place the cup between the two water bags 23 first, and then drive the two driving plates 25 to approach each other through the control unit 3, so that the two water bags 23 are squeezed on the surface of the cup. Since the surface of the water bag 23 is elastic, this clamping method is a relatively flexible clamping method, that is, it can not only achieve stable clamping of the water cup, but also will not excessively squeeze the surface of the water cup.

[0037] Embodiment three:

[0038] The second embodiment of the present application is to further improve the present application based on the first embodiment. Figures 1 to 6The inner walls of the two water bags 23 are fixedly installed with drawstrings 11. When the user controls the two driving plates 25 to move away from each other, the two driving plates 25 will pull the surfaces of the two water bags 23 respectively. At this time, the drawstrings 11 on the inner walls of the two water bags 23 will respectively pull the two water bags 23 close to the side of the cup, so that the surface of the water bags 23 leaves the surface of the cup more completely. A through groove 12 is provided on the surface of the driving disk 32, and a stirring rod 13 is slidably inserted into the inner wall of the through groove 12. The user can rotate the stirring rod 13 by rotating the rotating disk 14 arranged at one end of the stirring rod 13, thereby stirring the liquid in the cup.

[0039] Working principle of the present invention:

[0040] First, the user places the cup between the two water bags 23, and then rotates the drive disk 32, drives the drive wheel 3353 to rotate through the belt transmission, and drives the swing plate 331 to swing through the gear transmission, thereby driving the two drive plates 25, that is, clamping the water cup.

[0041] Secondly, when the user rotates the driving disk 32 90 degrees, a second bevel gear 101 meshing with the first bevel gear 3355 will be driven to rotate, and the second bevel gear 101 will drive a transmission gear 103 to rotate. The transmission gear 103 further drives the two racks 105 to rise and fall, thereby driving the water pressure plate 6 and the negative pressure plate 9 respectively installed on the surfaces of the two racks 105 (the moving directions of the water pressure plate 6 and the negative pressure plate 9 are opposite), thereby creating a negative pressure environment inside the negative pressure chamber 8 and filling the two water bags 23 with water.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
