Description

Technical Field

[0001] This utility model relates to the field of endoscope operating handles, and in particular to an endoscope operating handle with temperature regulation function. Background Technology

[0002] The operating handle of the industrial endoscope is the core control unit for monitoring tasks. It adopts an integrated design, which compactly integrates the display screen, guide mechanism, function buttons and light source adjustment module into the non-slip handle.

[0003] Currently, most industrial endoscope operating handles are susceptible to problems in low-temperature or high-temperature environments. Due to the poor thermal insulation of the display screen, the display screen can more easily affect the internal components of the device in low-temperature environments, causing a drop in internal temperature. Low temperatures can lead to voltage drops or unstable current in electronic components such as circuit boards and chips, potentially causing system crashes. High temperatures, on the other hand, can cause components to overheat, triggering protection mechanisms that prevent them from working or causing direct damage.

[0004] Based on the above problems, an endoscope operating handle with temperature regulation function is proposed. Utility Model Content

[0005] In view of this, the main purpose of this utility model is to provide an endoscope operating handle with temperature regulation function, which solves the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an endoscope operating handle with temperature regulation function, comprising a packaged back shell and a front shell disposed at the front end of the packaged back shell, a display screen is installed inside the front shell, a fixed bracket is disposed inside the display screen, a PTC heating element is disposed between the fixed bracket and the display screen, a main PCBA board is disposed inside the front shell, a packaged bottom shell is disposed at one end of the packaged back shell, and a heat sink is disposed at the front end of the packaged bottom shell.

[0007] As a preferred technical solution, a sealing ring is provided between the display screen and the front cover.

[0008] As a preferred technical solution, an NTC temperature sensing module is provided between the main PCBA board and the PTC heating element.

[0009] As a preferred technical solution, the NTC temperature sensing module is used to monitor temperature.

[0010] As a preferred technical solution, the heat sink is used to dissipate heat from the interior of the front shell and the encapsulated back shell.

[0011] As a preferred technical solution, a battery module is disposed inside the encapsulated back cover.

[0012] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, its main features are:

[0013] When this device is in use, when the main PCBA board and other components inside the device generate heat, the combination of the encapsulation bottom shell and the heat sink can dissipate the internal temperature of the device to the outside, completing the heat dissipation process and reducing the internal temperature of the device.

[0014] The NTC temperature sensing module is used to monitor the ambient temperature. When the ambient temperature is detected to be lower than the minimum temperature required for the device to operate, the main PCBA board controls the PTC heating element to start, thereby raising the internal temperature of the device. Once the minimum temperature is exceeded, the NTC temperature sensing module can detect this and then controls the main PCBA board to stop the PTC heating element from working, thus stopping the heating process.

[0015] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model 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 merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0023] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0024] Please see Figures 1 to 5 This utility model provides an endoscope operating handle with temperature regulation function, including a back cover 2 and a front cover 1 at the front end of the back cover 2. The front cover 1 and the back cover 2 are made of high-strength PC + 15% GF glass fiber and soft TPU through a two-color molding process, which ensures both high mechanical performance and reliable waterproof and dustproof effects. A display screen 3 is installed inside the front cover 1. A metal base plate is set on the back of the display screen 3. A fixing bracket 6 is set on the inner side of the display screen 3. A PTC heating element 5 is set between the fixing bracket 6 and the display screen 3. The PTC heating element 5 is installed on the metal base plate on the back of the display screen 3. The fixing bracket 6 is made of fire-resistant engineering plastic material. During heating, heat loss is reduced. The main PCBA board 8 is installed inside the front shell 1. The main PCBA board 8 generates heat during operation. This heat will cause the ambient temperature inside the front shell 1, the back shell 2, and the bottom shell 9 to rise. If the temperature exceeds the internal operating temperature of the device, it may cause the components to overheat, triggering the protection mechanism and preventing them from working or causing direct damage. The bottom shell 9 is installed at one end of the back shell 2. The heat sink 10 is used to dissipate heat from the inside of the front shell 1 and the back shell 2. The bottom shell 9 is made of aluminum alloy. The heat sink 10 is installed at the front end of the bottom shell 9. The heat sink 10 allows the temperature inside the front shell 1, the back shell 2, and the bottom shell 9 to be discharged through the bottom shell 9 and then through the heat sink 10, ensuring the heat dissipation of this device.

[0025] Please see Figures 1 to 5 A sealing ring 4 is provided between the display screen 3 and the front cover 1. The sealing ring 4 is used to prevent the external environment from entering the interior of the device through the gap between the front cover 1 and the display screen 3, thereby improving the stability of the internal environment of the device.

[0026] Please see Figures 1 to 5An NTC temperature sensing module 7 is installed between the main PCBA board 8 and the PTC heating element 5. The NTC temperature sensing module 7 is used to monitor the temperature. When the ambient temperature is lower than the minimum temperature required for the operation of this device, it can be detected. Then, the main PCBA board 8 controls the PTC heating element 5 to start, thereby raising the temperature of the internal environment of this device. When the temperature exceeds the minimum, the NTC temperature sensing module 7 can detect this, and then the main PCBA board 8 controls the PTC heating element 5 to stop working and stop the heating process.

[0027] Please see Figures 1 to 5 The battery module 11 is installed inside the encapsulated shell 2, and the battery module 11 is used to power the device.

[0028] Specifically, when this device is in use, when the main PCBA board 8 and other components inside the device generate temperature, the combination of the encapsulation bottom shell 9 and the heat sink 10 enables the internal temperature of the device to be dissipated to the outside, completing the heat dissipation process and reducing the internal temperature of the device.

[0029] Secondly, waterproof rings or O-rings are installed at the connection points of components to form a sealed waterproof space system, which prevents the performance from being affected in environments with low temperature, humidity, water vapor, dust, etc.

[0030] The NTC temperature sensing module 7 is used to monitor the ambient temperature. When the ambient temperature is detected to be lower than the minimum temperature required for the device to operate, the main PCBA board 8 controls the PTC heating element 5 to start, thereby raising the temperature of the internal environment of the device. When the minimum temperature is exceeded, the NTC temperature sensing module 7 can detect this and then controls the main PCBA board 8 to stop the PTC heating element 5 from working, stopping the heating process, thus realizing the temperature regulation function.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
