However, this system lacks a heating function, and in clinical applications, excessively low water temperatures can easily cause patient spasms, threatening their lives.

[0003] Although some water delivery devices currently have heating functions, there are safety hazards when using alternating current to heat liquids, and the heating effect is generally poor, the heating temperature is not easy to control, and the clinical application significance is limited.

[0004] Therefore, in view of the above-mentioned technical problems, how to provide a heating device with high heating efficiency, safety and reliability and good temperature control is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0028] It should be noted that in this embodiment, the orientation or positional relationship indicated by terms such as "upper," "lower," "front," and "rear" is based on the orientation or positional relationship shown in the accompanying drawings. It is used only for the convenience of describing this application and for simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application. Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Please refer to Figure 1 In this embodiment, an endoscope water supply heating device is provided. The device includes a power supply, a control system and a heating element 6. The power supply can be an AC mains power supply, which can provide 220V AC voltage.

[0031] The control system includes a controller 3 and a relay 5. The controller 3 can be a microcontroller unit (MUC). The controller 3 is connected to a power source via an AC-DC (AC to DC) power module, thereby ensuring a stable DC power supply. The control terminal of the controller 3 is connected to the coil of the relay 5, and the coil is energized based on the output signal from the control terminal.

[0032] The contacts of relay 5 are connected to the power supply and the wires 61 of heating element 6. The contacts can be normally open. When heating element 6 needs to be heated, controller 3 controls the coil to be energized, and the contacts of relay 5 are turned on, so that heating element 6 is connected to the power supply and energized for heating.

[0033] The heating surface of the heating element 6 is in contact with the outer wall of the cup 8 containing water or the pipe 9 conveying water, thereby heating the liquid in the cup 8 or the pipe 9 through heat conduction, which has high heating efficiency.

[0034] In summary, this application uses AC power as the main power source. The controller 3 is connected to the AC power source through the AC-DC power module 1, thereby providing the controller 3 with a relatively stable DC power supply. The coil of the control terminal relay 5 of the controller 3 is connected, thereby controlling whether the coil is energized or de-energized. The contacts of the relay 5 are connected to the power source and the heating element 6 respectively. When the coil is energized, the heating element 6 is connected to the power source and starts heating. Conversely, when the coil is de-energized, the heating element 6 stops heating, thereby enabling the heating element 6 to perform intermittent heating. This ensures both heating effect and safety when using AC power.

[0035] In the first embodiment, the heating element 6 is a silicone rubber heating plate 62, which is composed of a nickel-chromium alloy heating wire and a silicone rubber high-temperature insulating cloth, and can utilize the outer wall shape of the cup body 8. The cup body 8 is a cylindrical plastic cup body, and the heating surface of the silicone rubber heating plate 62 can be attached to the outer wall of the cylindrical plastic cup body to heat the liquid inside the cup body 8; wherein, the outer wall of the cup body 8 can be a side wall or a bottom wall, ensuring that the heat on the heating surface can be transferred to the liquid through the outer wall of the cup body 8.

[0036] Of course, to ensure the heating element has a sufficient heating area and improve the heating efficiency of the liquid, the silicone rubber heating plate 62 can be further attached to the circumferential side wall of the cylindrical plastic cup. Please refer to [reference needed]. Figure 2 Because the circumferential sidewall has a larger area than the bottom plate wall, the layout of the silicone rubber heating plate 62 is more flexible, and the silicone rubber heating plate 62 can be selected with different heating areas according to actual conditions to ensure heating efficiency of liquid.

[0037] In addition, the silicone rubber heating plate 62 can be set in a semi-enclosed or fully enclosed manner in the circumferential direction of the cylindrical plastic cup body to ensure sufficient heating area and guarantee heating efficiency.

[0038] In the second embodiment, the heating element 6 includes a heating element 63 and a heat insulation layer 64, please refer to... Figure 3 and Figure 4 The heating element 63 is provided with multiple heating channels 631 for accommodating the tube 9. After the heating element 63 is connected to the power supply through the relay 5, the heat generated by the heating element 63 will be transferred to the tube wall of the tube 9 through the channel wall of the heating channel 631. That is, the channel wall of the heating channel 631 is in contact with the outer wall of the tube 9. Furthermore, since there are multiple heating channels 631 and the channel walls of the heating channels 631 can be distributed circumferentially along the outer wall of the tube 9, the tube wall of the tube 9 has multiple heating positions, thereby ensuring that the tube 9 has a sufficient heating area and ensuring heating efficiency.

[0039] To facilitate the placement and removal of the tube 9 within the heating channel 631, an opening for placing and removing the tube 9 can be provided on one side of the heating channel 631. The tube 9 can be placed and removed through the opening. In this embodiment, to ensure the heating effect on the tube 9, a heat insulation layer 64 is also provided on the opening side of the heating channel 631. The heat insulation layer 64 is detachable, meaning that when placing or removing the tube 9, the heat insulation layer 64 can be removed or opened, and then reset after placement or removal. This allows the heat generated by the heating element 63 to be fully applied to the tube 9 and to the liquid inside the tube 9 through heat conduction.

[0040] Multiple heating channels 631 are arranged in parallel and side by side, and the tube 9 can be sequentially inserted into the heating channel 631. Please refer to the details. Figure 4 The heating channels 631 set in the above manner can make the tube body 9 periodically distributed on the heating element 63, making the layout of the heating channels 631 on the heating element 63 more reasonable and the structure of the heating element 63 more compact.

[0041] Please refer to Figure 1 The control system also includes a temperature sensor 7, which is installed on the heating element 6. The temperature sensor 7 is used to detect the heating temperature of the heating element 6. The temperature sensor 7 is connected to the controller 3, so that the temperature information can be fed back to the controller 3. The controller 3 controls the coil state of the relay 5 according to the temperature information, thereby realizing intermittent heating.

[0042] Specifically, there are at least two temperature sensors 7. One temperature sensor 7 is used to determine whether heating is needed. When the temperature detected by this temperature sensor 7 is lower than the set value, the controller 3 controls the coil of the relay 5 to be energized, and the heating element 6 starts heating. When the temperature detected by this temperature sensor 7 is higher than the set value, the controller 3 controls the heating element 6 to stop heating. The other temperature sensor 7 is used for temperature protection and temperature control. A maximum protection temperature is set, and the heating function is allowed to start only when the value of this temperature sensor 7 is lower than the maximum protection temperature limit.

[0043] In addition, a linear regulated power supply 2 is provided between the controller 3 and the ACDC power module 1 to ensure that the controller 3 has a stable input voltage. The output terminal of the controller 3 is connected to a display component 4, which can intuitively observe parameters such as heating temperature, heating time, relay 5 status, and voltage status, which will not be described in detail here.

[0044] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0045] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
