DETAILED DESCRIPTION

[0045] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0046] Example 1

[0047] A circulating cooling device for preparing medical oxygen, such as Figure 1 As shown, it includes an air inlet pipe 1, a connecting piece 2 is installed at the front and rear ends of the connecting piece 2, and two thin tubes 3 are installed in the air inlet pipe 1, which are used to differentiate the oxygen in motion. An air cooling mechanism 4 is installed on both sides of the air inlet pipe 1 for quickly cooling the oxygen. A liquid cooling mechanism 5 is installed on the air cooling mechanism 4 for further assisting the circulating cooling of the oxygen.

[0048] It needs to be explained that when the medical oxygen is prepared, the circulating cooling treatment can be carried out by using the device, first, the air inlet pipe 1 is installed by the connecting piece 2, then the oxygen is normally input into the air inlet pipe 1, the oxygen is divided under the action of the thin pipe 3, then the air cooling mechanism 4 and the liquid cooling mechanism 5 are started synchronously to fully cool the divided oxygen, and the oxygen after the treatment is discharged through the rear side of the air inlet pipe 1.

[0049] As shown in Figures 1-3 , the air cooling mechanism 4 comprises a ventilation cylinder 41 installed on the air inlet pipe 1, the air inlet pipe 1 is located in the inside of the ventilation cylinder 41, a refrigerating machine 42 is installed on the right side of the ventilation cylinder 41, an air outlet assembly 43 is rotatably installed on the left side of the ventilation cylinder 41, the air outlet assembly 43 comprises a rotating frame 4301 and a fan 4302, the rotating frame 4301 is rotatably connected with the ventilation cylinder 41, the fan 4302 is installed on the rotating frame 4301, and the fan 4302 is four in total, two magnetic plates 44 are provided, one is installed on the upper side of the left part of the ventilation cylinder 41, and the other is installed on the upper side of the air outlet assembly 43, and the two magnetic plates 44 are connected in an adsorbing mode.

[0050] It needs to be explained that when the oxygen is sent into the air inlet pipe 1, the refrigerating machine 42 is started synchronously, the cold air flow generated by the refrigerating machine 42 moves left along the ventilation cylinder 41, thereby fully cooling the oxygen divided by the thin pipe 3, then the air outlet assembly 43 is started, the fan 4302 starts to rotate after the air outlet assembly 43 is started, thereby guiding the cold air flow to move left and discharge, when it is needed to clean the inside or perform maintenance operation, the air outlet assembly 43 can be turned over and opened, so that the two magnetic plates 44 are no longer adsorbed, and then the operation can be performed by relying on the opening on the left side of the ventilation cylinder 41.

[0051] As shown in Figure 1 , Figure 4 and Figure 5 , the liquid cooling mechanism 5 comprises heat-conducting frames 51, two in total, which are installed on the upper sides of the left and right parts of the ventilation pipe respectively, liquid pumps 52, two in total, one of which is installed on the front side of the right heat-conducting frame 51, and the other is installed on the left side of the left heat-conducting frame 51, liquid guide pipes 53, two in total, which are installed between the heat-conducting frames 51 and connected with the corresponding liquid pumps 52, lifting frames 54 which are slidably installed in the heat-conducting frames 51, the lifting frames 54 are connected with an arc-shaped connecting frame, an electric push rod 55 which is installed on the upper side of the front part of the ventilation cylinder 41, the extension end of the electric push rod 55 is connected with the arc-shaped connecting frame, a filter 56 which is installed in the lifting frame 54 and corresponds to the connection position of the liquid guide pipe 53, for filtering and removing impurities of the cooling water.

[0052] It should be noted that when the air cooling mechanism 4 is started, the liquid cooling mechanism 5 is started at the same time, and the water pump starts to flow the cooling water in the heat conduction frame 51, so that the cooling water moves along the liquid guide pipe 53, thereby assisting the air cooling mechanism 4 to cool the oxygen, improving the cooling efficiency. After a period of use, the electric push rod 55 is started, and the upward movement of the telescopic end of the electric push rod 55 drives the arc-shaped connecting rod to move upward, so that the lifting frame 54 moves upward to lift, facilitating the operator to clean the filter 56, and avoiding the blockage of the heat conduction frame 51.

[0053] Embodiment 2

[0054] Based on the embodiment 1, as shown in Figure 1 , Figure 6 and Figure 7 , the diffusion mechanism 6 is further included, the diffusion mechanism 6 includes the air guide frame 61, the air guide frame 61 is installed on the left part of the ventilation cylinder 41, two groups of air guide plates 62 are rotatably connected to the left side in the air guide frame 61, and the synchronous assembly 63 is connected between the lower sides of the air guide plates 62. The synchronous assembly 63 includes synchronous wheels and a synchronous belt, the synchronous wheels are installed at the lower ends of the corresponding air guide plates 62, and the synchronous belt is wound between the synchronous wheels.

[0055] It should be noted that in the process of circulating cooling of oxygen, in order to maximize the utilization of wind cooling, the angle of the guide plate is adjusted by the synchronous assembly 63, so that the left moving cold air flow can be backflowed under the guidance of the guide plate, avoiding the cold air flow moving too fast, and further improving the cooling effect.

[0056] As shown in Figure 1 and Figure 8 , the anti-overflow mechanism 7 is further included, the anti-overflow mechanism 7 includes the pressing plate 71, the lifting frame 54 is connected with the pressing plate 71, the heat conduction frame 51 is slidably connected with the anti-overflow frame 72, the pressing plate 71 is used for pressing and limiting the adjacent anti-overflow frame 72, the anti-overflow frame 72 is used for preventing the cooling water from overflowing, the heat conduction frame 51 is connected with the fixed seat 73, and the anti-overflow frame 72 and the adjacent fixed seat 73 are connected with the first elastic sheet 74.

[0057] It should be noted that in the normal state, the anti-overflow frame 72 and the lifting frame 54 are located at the same horizontal height, and the pressing plate 71 always keeps pressing and limiting the anti-overflow frame 72. With the upward movement of the lifting frame 54, the pressing plate 71 also moves upward synchronously. At this time, the anti-overflow frame 72 will not be extruded, and in the initial state, the first elastic sheet 74 is in a stressed and compressed state. Under the action of the first elastic sheet 74, the anti-overflow frame 72 will slide upward and pop out, thereby blocking the side of the heat conduction frame 51 to prevent the cooling water from overflowing.

[0058] As shown in Figure 1 , Figure 9 andFigure 10 As shown in FIG. 1, the air conditioner further comprises a pressing mechanism 8, the pressing mechanism 8 comprises a fixed plate 82, the fixed plate 82 is connected to the inner side of the air guide frame 61, a second elastic sheet 83 is installed on the fixed plate 82, a pressing piece 81 is connected to the second elastic sheet 83, the pressing piece 81 is slidably connected to the air guide frame 61, and the pressing piece 81 is used for pressing and limiting the synchronous assembly 63.

[0059] It should be noted that, in order to ensure that the synchronous assembly 63 can normally operate, the second elastic sheet 83 cooperates with the pressing piece 81 to keep the synchronous assembly 63 pressed, so that the synchronous assembly 63 can normally operate, and the idling between the synchronous wheel and the synchronous belt is avoided.

[0060] As shown in FIG. 1, Figure 1 and Figure 11 As shown in FIG. 1, the air conditioner further comprises a dustproof mechanism 9, the dustproof mechanism 9 comprises a mounting plate 91, the mounting plate 91 is connected to the front and rear sides of the refrigerating machine 42, and a dustproof frame 92 is connected between the right sides of the mounting plates 91.

[0061] It should be noted that the dustproof frame 92 blocks the air inlet on the right side of the refrigerating machine 42 to prevent dust from adhering too much and causing the refrigerating machine 42 to fail to work normally.

[0062] It should be understood that the above description is only for illustrative purposes and does not mean to limit the present application. Those skilled in the art will understand that the variations of the present application will be included in the scope of the claims herein.
