[0023] This embodiment provides a vehicle-mounted drinking water device, which includes: a fixed seat 100, a water source component 200, a water outlet component 300, a heating component 400 and a central control component. The fixed seat 100 is connected to the body of the motor vehicle. A placement cavity 101 is opened on the fixed seat 100. The water source component 200 is arranged inside the placement cavity 101. The heating component 400 and the water outlet component 300 are both arranged on the fixed seat 100. The water inlet end of the heating component 400 is connected to the water source component 200, and the water outlet end of the heating component 400 is connected to the water outlet component 300. The central control component is electrically connected to the heating component 400, and the central control component can be connected to an external power supply device. The central control component is used to drive the heating component 400 to heat the liquid.
[0024] Please refer to Figure 1As shown, the fixing base 100 can be fixed to the rear of the center console between the driver and co-driver seats in the motor vehicle by means of bolts, clips or adhesive devices. It is understood that the cup holder of the motor vehicle is set between the driver and co-driver seats for placing water cups, etc. The fixing base 100 is set at the rear of the center console between the driver and co-driver seats, and the water outlet head 301 of the water outlet assembly 300 can be just right in line with the cup opening on the cup holder. When receiving water, there is no need to hold the cup in hand, just put the cup into the cup holder. This is convenient for operation and avoids accidents such as liquid spillage caused by vehicle shaking, which may cause burns. The fixing base 100 is provided with a heating assembly 400 and a water source assembly 200. The water source assembly 200 is placed in the placement cavity 101 on the fixing base 100. The fixing base 100 protects the water source assembly 200, ensures the stability and safety of the water source assembly 200, and improves the continuous water supply of the entire device. The water source assembly 200 is connected to the water inlet of the heating assembly 400 via a pipe. After being heated by the heating assembly 400, the liquid flows through the water outlet to the water outlet assembly 300. The heated liquid is then poured into cups in the cup holder for drinking by passengers in the vehicle. The heating assembly 400 can be a commercially available instant heating assembly with adjustable temperature. This provides instant water delivery, eliminating the need for repeated heating of the liquid and the need to store hot water. This provides fast heating speed and eliminates the risk of boiling water spillage, making it safer. The heating assembly 400 is electrically connected to the central control assembly, which can adjust the heating temperature of the heating assembly 400, allowing users to adjust the water outlet temperature according to their actual needs and enhance user comfort. The central control assembly can be connected to different power supply devices to adapt to different vehicle models. For example, different power supply devices can be provided for different vehicle models, such as pure electric and hybrid vehicles, to better meet the power supply needs of the heating assembly 400. Furthermore, the entire vehicle-mounted drinking water device is detachably connected to the vehicle, making it suitable for drinking water supply in various scenarios, such as outdoor or other mobile devices, in addition to being placed on the vehicle.
[0025] Optionally, in some possible embodiments, the water source component 200 includes a mounting frame 201 and a liquid storage bottle 202, the mounting frame 201 is arranged on the fixing seat 100, and the mounting frame 201 is provided with a liquid inlet for connecting to the liquid storage bottle 202, and the liquid inlet is connected to the heating component 400 through a special pipe.
[0026] Please refer to Figure 1As shown, the liquid storage bottle 202 can be an existing commercially available beverage bottle made of plastic or glass. After purchasing mineral water or other beverages, the user opens the bottle cap and connects the bottle mouth with the liquid inlet on the mounting frame 201 to complete the installation. A sealing ring and a fixed thread can be provided at the liquid inlet to cooperate with the thread at the beverage bottle mouth. By rotating and tightening the liquid storage bottle 202, the stability and sealing after the connection are improved. It is understood that the bottle mouth sizes of existing beverage bottles are generally standardized. The liquid inlet provided on the mounting frame 201 can be adapted to the installation of most beverage bottles on the market. The user does not need to clean the liquid storage bottle 202 or specifically fill the liquid storage bottle 202 with liquid. The beverage bottle can be directly used as the liquid storage bottle 202 and can be directly replaced after drinking. The operation is convenient and quick.
[0027] Alternatively, see Figure 3 As shown, in some possible embodiments, the liquid inlet is configured as a tapered structure, with the diameter of the liquid inlet gradually decreasing vertically from top to bottom. The inner wall of the liquid inlet is provided with tapered threads or threads of varying sizes from top to bottom, allowing the liquid inlet to connect to liquid storage bottles with different calibers. Optionally, in some possible embodiments, the mounting frame 201 is provided with a placement opening 102 that communicates with the placement cavity 101. A protective cover 500 is provided over the placement opening 102, which is detachably connected to the mounting frame 201.
[0028] Please refer to Figure 1 As shown, a placement opening 102 is provided on one side of the placement chamber 101. This opening connects the placement chamber 101 to the outside, making it easier for the user to secure the liquid storage bottle 202 to the mounting bracket 201. A protective cover 500 covers the placement opening 102. This seal ensures a tight seal within the placement chamber 101 and ensures the stability of the liquid storage bottle 202 after installation. The protective cover 500 is detachably connected to the mounting bracket 100, making it easier for the operator to open the protective cover 500 and install the liquid storage bottle 202.
[0029] Optionally, in some possible embodiments, the mounting frame 201 is slidably disposed on the fixing base 100 , and the mounting frame 201 is driven to move, so that the liquid storage bottle 202 moves to the outside of the placement cavity 101 through the placement opening 102 .
[0030] Please refer to Figure 1 As shown, the mounting bracket 201 is slidably mounted at the bottom of the placement chamber 101. The mounting bracket 201 can be moved outside the placement chamber 101 by sliding, making it easier for the user to remove or install the liquid storage bottle 202. It will be appreciated that the bottle mouth of the liquid storage bottle 202 needs to be aligned with the liquid inlet on the mounting bracket 201, and may require threaded or snap fasteners for securement. This makes operation in the narrow placement chamber 101 inconvenient and may also result in liquid leakage. Moving the mounting bracket 201 outside the placement chamber 101 facilitates user observation and operation, improves operational efficiency, and prevents liquid leakage.
[0031] Optionally, in some possible embodiments, a shock absorbing device 600 is provided inside the placement cavity 101 , and the shock absorbing device 600 abuts against the peripheral wall of the liquid storage bottle 202 .
[0032] Please refer to Figure 2 As shown, the inner wall of the placement cavity 101 is provided with a clamping block, which is connected to the fixing base 100 via a spring to form a shock-absorbing device 600, which is used to clamp and fix the liquid storage bottle 202, ensuring the stability of the liquid storage bottle 202. It is understood that during the operation of a motor vehicle, there will be bumps and shakes, which can easily cause the liquid storage bottle 202 to shake and fall off. The shock-absorbing device 600 helps to fix the liquid storage bottle 202, so that the liquid storage bottle 202 and the fixing base 100 are in a relatively stable and static state, preventing leakage. It also ensures stable hot water output even on bumpy roads, avoiding interruptions in water supply due to liquid shaking.
[0033] It should be noted that in this embodiment, the shock-absorbing device can also be separately installed on the protective cover and the inner wall of the placement cavity. When the protective cover is removed, the shock-absorbing device on one side is automatically removed, making it easier to install or remove the liquid storage bottle. Conversely, when the protective cover is closed, the shock-absorbing device on the protective cover and the witness device in the placement cavity interact to clamp and fix the liquid storage bottle, ensuring the stability of the liquid storage bottle.
[0034] Optionally, in some possible embodiments, the water source assembly 200 further includes a filter device 700 , and the filter device 700 is used to filter the liquid in the liquid storage bottle 202 .
[0035] Please refer to Figure 2 As shown, a filter device 700 is detachably mounted on mounting frame 201 for filtering liquids. In outdoor environments where it's impossible to purchase or collect directly drinkable liquids, a liquid storage bottle 202 can be used to collect relatively clean liquids such as river water or rainwater. Filter device 700 is then mounted on the mouth of liquid storage bottle 202 and connected to the liquid inlet on mounting frame 201. The filtered liquid is then heated by a heating device and ready for drinking. Filter device 700 provides an emergency response, allowing natural water sources to be used as drinking water in special circumstances, thereby enhancing the practicality of the entire device.
[0036] Optionally, in some possible embodiments, the water source assembly 200 further includes a detection device for detecting the amount of liquid remaining in the liquid storage bottle 202 .
[0037] The detection device can be a gravity detection device, which is installed on the mounting frame 201 and determines the amount of liquid remaining in the liquid storage bottle 202 by detecting the weight of the liquid in the liquid storage bottle 202. When the remaining liquid amount is detected to be lower than a preset value, the user can be immediately reminded to refill the liquid through a light or sound alarm device.
[0038] Optionally, in some possible embodiments, the detection device may also be a liquid flow detector or a liquid level detector, which determines whether the liquid is used up by detecting the liquid level in the liquid storage bottle 202 or the liquid flow in the liquid pipeline.
[0039] Optionally, in some possible embodiments, the water outlet component 300 includes a water outlet head 301 and a power device 302, both of which are arranged on the fixed seat 100, and the water outlet head 301 is connected to the liquid outlet end of the heating component 400 through a liquid pipe, and the power device 302 is used to transport the liquid of the water source component 200 to the water outlet head 301 through the heating component 400.
[0040] Please refer to Figure 1 As shown, the power device 302 can be a liquid pump, and the water outlet 301 is connected to the liquid outlet end of the heating component 400 through the liquid pump. The liquid in the liquid storage bottle 202 is transported to the water outlet 301 by the liquid pump to realize automatic water supply.
[0041] Optionally, in some possible embodiments, the water outlet assembly 300 further includes a driving device 303, the water outlet head 301 is movably connected to the fixed seat 100, the water outlet head 301 has multiple water outlet positions, the driving device 303 is driven and cooperated with the water outlet head 301, and the driving device 303 is used to drive the water outlet head 301 to switch between multiple water outlet positions.
[0042] It is understood that existing automobile frames are typically equipped with multiple cup holders to accommodate multiple drinking cups. Therefore, the water outlet 301 is movably mounted on the fixed base 100. Specifically, when the cup holders on the cup holder are arranged along the length of the vehicle body, the water outlet 301 can be slidably mounted on the fixed base 100, and the drive device 303 drives the water outlet 301 to move along the length of the vehicle body, thereby moving the water outlet 301 above different cup holders. When the cup holders on the cup holder are arranged in a direction perpendicular to the vehicle body, the water outlet 301 can be rotatably connected to the fixed base 100, and the drive device 303 drives the water outlet 301 to swing back and forth, thereby adjusting the water outlet 301 to different water outlet positions. The water outlet 301 is movably mounted on the fixed base 100, and water can be filled into cups at different positions by switching the water outlet position. There is no need to move the cups when multiple people use the cup holder, making operation more convenient and quick. During the process of the water outlet head 301 switching the water outlet position, the heating component 400 and the power device 302 work simultaneously. When the water outlet head 301 moves to the working position, the heating component 400 has completed the startup operation. At this time, the liquid has been heated and flows out from the water outlet head 301. The whole process is very quick and convenient.
[0043] Optionally, in some possible embodiments, the central control component includes a control circuit board, an operation panel and a display 801, the operation panel and the display 801 are arranged on the fixing base 100, and the operation panel and the display 801 are electrically connected to the control circuit board.
[0044] The control circuit board can be a conventional programmable integrated circuit board, integrated with the control circuitry. The control program is set via a storage device and a control chip. The control circuit board is electrically connected to an operation panel and display 801. The operator can view information such as liquid temperature and water output through display 801 and adjust relevant parameters through the operation panel. Display 801 can also generate an alarm when the liquid in the liquid storage bottle 202 is low, allowing the user to promptly monitor the remaining liquid level.
[0045] Optionally, in some possible embodiments, the central control component further includes a protection device 802, which is used to limit the water outlet head 301 to ensure that the water outlet head 301 moves within a set range, thereby preventing the water outlet head 301 from exceeding the limit position when moving and causing damage to the equipment.
[0046] In summary, the present invention provides an in-vehicle drinking water device. During use, the user opens the protective cover 500, pulls out the mounting bracket 201 of the water source assembly 200, screws the bottle mouth of the bottled water onto the water inlet on the mounting bracket 201, and closes the protective cover 500. The shock-absorbing device 600 within the placement chamber 101 stabilizes the water bottle within the placement chamber 101, maintaining a relatively stable and stationary state between the bottle and the mounting base 100. Water level data is detected and transmitted to the central control assembly, which displays the relevant information on the display 801. When the water level falls below 10%, the number on the display 801 flashes three times. The central control assembly features a child protection function. The user must disable the protection via the operation panel before setting the desired water temperature and volume. This prevents children from operating or accidentally touching the water, enhancing safety. The values set by the central control assembly remain unchanged over time, consistent with user preferences, and are unaffected by the vehicle being turned off or on again, until they are reset. When water is needed, first release the protection, then click the water outlet button. The power unit 302 starts, providing suction to transport water to the heating component 400. By adjusting the power of the heating tube, the water is heated to the set temperature during flow, and the water output is controlled by the tube diameter and water flow parameters. At the same time, the drive unit 303 starts, extending the water outlet head 301 outward to the water outlet position, achieving water heating and displacement of the water outlet head 301 within the same time (4 seconds). Depending on the characteristics of different vehicle models, the water outlet head 301 of this system is divided into two categories: one is telescopic, serving two water cups arranged vertically. Click the left water outlet button, and the water outlet head 301 is driven by the drive unit 303 to extend forward 7cm (the distance is adjustable, the same below); click the right water outlet button, and the water outlet head 301 extends forward 13cm, filling two water cups in different positions, one in front and one in the back. The other type is a rotary type, which serves two water cups arranged horizontally. Click the water outlet button on the left, and the mechanical arm drives the water outlet head 301 to rotate 85 degrees counterclockwise (the angle is adjustable, the same below) to fill the left water cup; click the water outlet button on the right, and the mechanical arm rotates 40 degrees counterclockwise and extends 6 cm outward, rotating and sending the water outlet head 301 to fill the right water cup. After completing the set water output, the mechanical conveying device automatically resets. In special circumstances where it is necessary to drink wild raw water, the filter device 700 can be taken out, and the end of the filter device 700 can be tightened onto the water inlet. Use a water storage bottle to take a bottle of natural water, tighten the bottle mouth onto the filter device 700, and you can get drinking water that meets drinking conditions.
[0047] It should be noted that, unless there is any conflict, the features in the embodiments of this application can be combined with each other.
[0048] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
