[0037] Example 1

[0038] This embodiment provides a water tank to solve the problem in the related art that the hot and cold water tanks of the medical temperature controller are independently arranged, occupy a large space, cannot be interconnected, and are inconvenient to use.

[0039] See also Figure 1 , Figure 2 , a water tank for a medical temperature controller. The water tank includes a box body 100, a partition assembly 200 and a connecting assembly 300. The partition assembly 200 is disposed in the box body 100, and the partition assembly 200 divides the box body 100 into a first chamber 110 and a second chamber 120. A first connecting port 111 is provided on the first chamber 110, and a second connecting port 121 is provided on the second chamber 120. The connecting assembly 300 can connect the first connecting port 111 with the second connecting port 121, and the first connecting port 111 and the second connecting port 121 are connected in one direction.

[0040] Specifically, when using the water tank of this embodiment, water is injected into the box body 100 so that the first chamber 110 and the second chamber 120 are both filled with water. One of the first chamber 110 and the second chamber 120 heats or cools the water to a preset temperature, and then supplies the water to the application sheath of the medical temperature controller, and then returns to the application water cooling head to form a water circuit circulation for use by the medical temperature controller.

[0041] During use, the first chamber 110 or the second chamber 120 can be unidirectionally connected through the connecting component 300, so that the chamber that consumes less water can replenish water to the chamber that consumes more water, so that the water levels in the first chamber 110 and the second chamber 120 can be kept level, to ensure that the water in the first chamber 110 and the second chamber 120 can continue to supply the medical temperature controller, to avoid the situation where the water in one chamber is consumed while there is still a lot of water left in the other chamber, which affects the normal operation of the medical temperature controller, making this embodiment easy to use.

[0042] The water tank provided in this embodiment can integrate the cold water tank and the hot water tank into the same box body 100, reduce the floor space of this embodiment, improve the space utilization and portability of this embodiment, and make this embodiment easy to use. In addition, the first chamber 110 and the second chamber 120 are connected in one direction, so that the first chamber 110 can supply water to the second chamber 120, or the second chamber 120 can supply water to the first chamber 110, thereby improving the reliability of this embodiment when in use, and further making this embodiment easy to use. Furthermore, the one-way connected first chamber 110 and the second chamber 120 can also separate the cold and hot water from each other, reduce the degree of mutual influence between the cold and hot water chambers, and improve the practicality of this embodiment.

[0043] In some embodiments, for example, Figure 1 , Figure 3 , Figure 5 As shown, the partition assembly 200 includes a partition, the edge of which abuts against the inside of the box 100, and the edge of the partition is sealed and connected to the box 100. The first chamber 110 and the second chamber 120 are separated by the partition to ensure that the first chamber 110 and the second chamber 120 are not connected to each other, so as to avoid heat exchange between the cold and hot water in the first chamber 110 and the second chamber 120, which affects their respective temperatures.

[0044] In some embodiments, for example, Figure 2 , Figure 4 As shown, the box body 100 includes a bottom plate 130, and the first communication port 111 and the second communication port 121 are both arranged on the bottom plate 130. The communication component 300 includes a communication groove, which is also arranged on the bottom plate 130, and the communication groove can connect the first communication port 111 and the second communication port 121. The communication groove is arranged on the bottom plate 130, and the first communication port 111 and the second communication port 121 are connected through the communication groove. On the one hand, the direct contact area between the first chamber 110 and the second chamber 120 can be reduced, and the temperature of the water in the first chamber 110 and the second chamber 120 can be avoided. Due to the large fluctuation of the communication groove, the temperature of the water in the first chamber 110 and the second chamber 120 is kept stable. On the other hand, the communication groove is arranged at the bottom of the box body 100, which can reduce the space occupied by this embodiment and further improve the space utilization rate of this embodiment.

[0045] It is understandable that if the connecting groove is set on the side wall or other positions of the box body 100, that is, the connecting groove is easily exposed to the field of vision of other unrelated personnel, resulting in the connecting groove being easily hit by human or non-human factors, causing damage to the present embodiment. In addition, if the first connecting port 111 and the second connecting port 121 are connected by water pipes, pipelines and other equipment, not only will the space occupied be larger, but the pipeline will also be easily damaged or bent, resulting in problems affecting the connectivity between the first connecting port 111 and the second connecting port 121. Therefore, the connecting groove can improve the structural rationality and reliability of the present embodiment.

[0046] In some embodiments, for example, Figure 2 , Figure 4 As shown, the connecting groove is arranged on the side of the bottom plate 130 away from the partition assembly 200. The connecting groove is sealed and connected to the first connecting port 111 and the second connecting port 121; and a one-way valve is arranged in the connecting groove. The connecting groove is arranged on the bottom plate 130 and at the bottom of the bottom plate 130, which can further improve the space utilization rate of the present embodiment and ensure the portability of the present embodiment; the connecting groove is arranged on the bottom plate 130, which can also protect the connecting groove to prevent other unrelated personnel from touching the connecting groove and affecting the connecting groove, thereby improving the reliability of the present embodiment. The connecting groove is sealed and connected to the first connecting port 111 and the second connecting port 121, which can prevent water leakage and seepage at the connection between the connecting groove and the box body 100 of the present embodiment, thereby further improving the reliability of the present embodiment.

[0047] In addition, a one-way valve is provided in the connecting groove, so that, according to actual needs, the first chamber 110 can supply water to the second chamber 120 in one direction, or the second chamber 120 can supply water to the first chamber 110 in one direction. Specifically, the chamber consuming less water can supply water to the chamber consuming more water in one direction, so that the water volume in the two chambers is balanced, the use time of this embodiment is extended, and the practicality of this embodiment is improved.

[0048] In some embodiments, for example, Figure 1 , Figure 3 , Figure 5 As shown, the volume of the first chamber 110 is set to V1, and the volume of the second chamber 120 is set to V2, satisfying: V1<V2. The volume of the first chamber 110 is smaller than the volume of the second chamber 120. In this way, a temperature control component is arranged outside the first chamber 110 so that the water temperature in the first chamber 110 can be heated or cooled to a preset temperature. Since the volume of the first chamber 110 is small and the amount of water carried is also small, the water temperature in the first chamber 110 can be quickly changed to a suitable temperature when heated.

[0049] In addition, the temperature control component arranged outside the first chamber 110 usually adopts a semiconductor refrigerator. In actual use, by controlling the polarity of the switching semiconductor, the semiconductor refrigerator can be controlled to heat or cool, thereby controlling the water in the first chamber 110 to heat up or cool down. The working principle of the semiconductor refrigerator is that when direct current passes through a galvanic couple formed by two different semiconductor materials in series, heat can be absorbed and released at both ends of the galvanic couple respectively. That is, one side of the semiconductor will cool down and the other side will heat up. To achieve the preset cooling capacity on one side, the heat on the other side needs to be dissipated, and the semiconductor refrigerator can continue to cool down. On this basis, the second chamber 120 is larger in volume and can carry more water at room temperature, that is, it can effectively dissipate the heat or cold on the semiconductor refrigerator to balance the semiconductor refrigerator so that it can work for a long time, thereby ensuring the heating or cooling effect of the water in the first chamber 110 of this embodiment.

[0050] It should be noted that, when using this embodiment, if the connecting groove can be connected in one direction, so that the second chamber 120 can supply water to the first chamber 110, then after the hot water in the first chamber 110 is consumed, the room temperature water in the second chamber 120 can be replenished to the first chamber 110 in time, and since the amount of a single replenishment is small, the temperature control component arranged outside the first chamber 110 can quickly cool or heat the temperature in the first chamber 110 to change it to the target temperature, so as to facilitate the present embodiment to supply water to the medical temperature controller.

[0051] It can be understood that during the use of this embodiment, the water in the first chamber 110 and the second chamber 120 is continuously consumed, and the first chamber 110 and the second chamber 120 maintain one-way communication, that is, the water level in the first chamber 110 and the second chamber 120 is continuously decreasing. When the first chamber 110 is used as a heating chamber, due to the small volume of the first chamber 110, the water in the first chamber 110 can be quickly heated to the target temperature. In subsequent use, even if the second chamber 120 supplies a large amount of water to the first chamber 110, the water content in the first chamber 110 is always less than the water content of the first chamber 110 before use, that is, no matter how much water the second chamber 120 supplies to the first chamber 110, the temperature change speed in the first chamber 110 is getting faster and faster, ensuring that the first chamber 110 can stably and reliably provide water of preset temperature for the medical temperature controller, thereby improving the reliability of this embodiment.

[0052] In some embodiments, for example, Figure 3 , Figure 4As shown, a mounting hole 131 communicating with the outside is provided in the first chamber 110, and a temperature sensor is provided in the mounting hole 131. The temperature sensor is provided in the first chamber 110, and the temperature in the first chamber 110 is monitored in real time by the temperature sensor, so as to ensure that the user can clearly know the water temperature supplied to the medical temperature controller, and prevent accidents due to inappropriate water temperature during use.

[0053] In some embodiments, for example, Figure 3 , Figure 4 As shown, at least two mounting holes 131 are provided in the first chamber 110, and a temperature sensor is provided in each mounting hole 131. By providing multiple temperature sensors in the first chamber 110 and performing temperature detection on multiple points in the first chamber 110 at the same time, the comprehensiveness of the detection can be improved to determine whether there is uneven heating in the first chamber 110 or differences in water temperature at various positions, and when a single temperature sensor fails or other problems result in the inability to detect the temperature, the temperature in the first chamber 110 can still be detected by relying on other temperature sensors, thereby increasing the fault tolerance of the present embodiment and improving the reliability of the present embodiment.

[0054] In some embodiments, for example, Figure 6 As shown, the box body 100 includes a top plate 140, and the top plate 140 can block the first chamber 110 and the second chamber 120. A water inlet 141 and an overflow port 142 are provided on the top plate 140, and the water inlet 141 and the overflow port 142 are both connected to any one of the first chamber 110 and the second chamber 120. The water inlet 141 is provided on the top plate 140, and water is added to the first chamber 110 through the water inlet 141. Since the first chamber 110 is connected to the second chamber 120, water can be added to any chamber through the water inlet 141, and the box body 100 can be filled with water.

[0055] It should be noted that the height of the partition assembly 200 in the box body 100 is lower than the height of the side wall of the box body 100. In this way, after the first chamber 110 and the second chamber 120 are filled with water, the overflow port 142 is set at any position, and the water can overflow normally. In addition, when the first chamber 110 and the second chamber 120 are connected in one direction, since the position of the partition assembly 200 is relatively low, the water inlet 141 is set at any position, and the two chambers can be filled with water. Furthermore, in actual use, if the second chamber 120 can supply water to the first chamber 110 in one direction, then setting the water inlet 141 on the top plate 140 above the second chamber 120 can make this embodiment more convenient to use and improve the practicality of this embodiment.

[0056] In some embodiments, for example, a liquid level sensor is further provided in the box 100, and the liquid level sensor is provided in the first chamber 110 or the second chamber 120. The liquid level sensor is provided in the box 100, so that the water level in the box 100 can be observed intuitively, and then the amount of water in the box 100 can be understood, which is convenient for the user to control the amount of water, replenish or drain water in the box 100 in time, so that the present embodiment is easy to use. When adding water, it is also possible to determine whether the water is added in place by the liquid level sensor, and fill the present embodiment with water when no water overflows from the overflow port 142. It is understandable that when the liquid level sensor in the present embodiment does not work properly, or the operator misoperates, resulting in the failure to pay attention to the change of the liquid level in the box 100 in time, after the box 100 is filled, the excess water will overflow from the overflow port 142, thereby reminding the operator that the water in the box 100 is replenished in place.

[0057] In some embodiments, for example, Figure 1 , Figure 7 As shown, the first chamber 110 is provided with a first water outlet 112 and a first water return port 113, and the second chamber 120 is provided with a second water outlet 122 and a second water return port 123. The first chamber 110 discharges water outward through the first water outlet 112 and takes in water inward through the first water return port 113 to form a connected water circuit cycle. Correspondingly, the second chamber 120 discharges water outward through the second water outlet 122 and takes in water inward through the second water return port 123 to form a connected water circuit cycle. When the present embodiment is not used for a long time and needs to be drained, the water in the first chamber 110 and the second chamber 120 can be discharged through the first water outlet 112 and the second water outlet 122, which further makes the present embodiment easy to use.

[0058] Example 2

[0059] A medical temperature controller includes a first water-using component, a second water-using component, and a water tank in any one of the above embodiments. The first water-using component is connected to a first chamber 110 , and the second water-using component is connected to a second chamber 120 .

[0060] The medical temperature controller provided in this embodiment includes the water tank in any one of the above embodiments, and has all the beneficial effects of the water tank in the above embodiments, which will not be described in detail here.

[0061] The first water-using component includes an application water pump, an application jacket and an application water cooling head.

[0062] When using this embodiment, the water outlet of the first chamber 110 is connected to the application water pump, and the application water pump is connected to the application jacket and the application water cooling head in sequence. The water in the first chamber 110 is pushed by the application water pump, and the water in the first chamber 110 is circulated to the water inlet of the application jacket, and then the application water is circulated in the application jacket, and then from the return water port of the application jacket to the water inlet of the application water cooling head, and is used by the application water cooling head. The return water port of the application water cooling head is then reconnected to the return water port of the first chamber 110, forming a water circulation waterway of the first chamber 110.

[0063] The second water-using component includes a cooling water pump, a cooling water cooling head, a drain valve and a condenser.

[0064] The water outlet of the second chamber 120 is connected to the heat dissipation water pump, which is connected to the heat dissipation water head, which is connected to the second chamber 120 through the condenser. The drain valve is arranged between the heat dissipation water head and the condenser, and the heat dissipation water pump can circulate the water in the second chamber 120 to the water inlet of the heat dissipation water head. The heat dissipation water head is closely attached to one side of the semiconductor refrigerator of the medical temperature controller. By controlling the polarity of the semiconductor, the polarity of the semiconductor refrigerator can be reversed without changing the structure, so as to perform cooling or heating. Therefore, the heat dissipation water head can dissipate the heat or cold accumulated on the other side of the refrigerator, thereby improving the efficiency of the medical temperature controller of this embodiment to reach the preset temperature. The return water port of the heat dissipation water head is connected to the water inlet of the condenser through a three-way joint. The condenser can circulate the water in the second chamber 120. The condenser is provided with a heat dissipation element, which can dissipate the heat on the condenser.
