Description

Technical Field

[0002] This invention relates to the field of vehicle-mounted water dispenser technology, and more specifically to a multi-functional vehicle-mounted water dispenser. Background Technology

[0003] Currently, the production and manufacturing of trucks, passenger cars, and new energy vehicles have developed rapidly, making professional in-vehicle drinking water equipment indispensable. As we all know, long-distance drivers need hot water to replenish their energy during long journeys, for example, to make tea, instant noodles, or coffee. Especially in winter and at night, having hot water readily available in the vehicle is a very practical measure.

[0004] A prior art patent with publication number CN208017380U discloses a solution including a water tank and a cold water outlet. The upper end of the water tank has a groove, and a water dispenser is embedded inside the groove. A water receiving tank is located on the lower left side of the inside of the water dispenser, and a cup holder is installed on the upper end of the water receiving tank. A water outlet is located inside the cup holder, and a hot water outlet is located above the cup holder. A switch button is connected above the hot water outlet. A first water pump is fixed on the lower right side of the inside of the water tank, and a water pipe is connected to the top of the first water pump. A first rotating drum is embedded on the lower right side of the inside of the water dispenser, and a hot water tank is located on the upper right side of the inside of the water dispenser. A hot water inlet is installed at the bottom of the inside of the hot water tank. This improved vehicle-mounted water dispenser uses a water tank, replacing the base of the previous water dispenser, and placing the water tank at the bottom of the water dispenser, reducing the footprint required by the water dispenser.

[0005] As existing devices are used, the shortcomings of this technology have gradually become apparent, mainly in the following aspects: First, existing vehicle-mounted water dispensers can only add water to the water tank, which is especially problematic when the tank is not used for a long time, as bacteria can easily grow inside, affecting the safety of drinking water.

[0006] Secondly, bottled purified water is usually kept in the driver's cab of the vehicle, which means that the bottled purified water still needs to be poured into the water tank for water supply, which is inconvenient.

[0007] Third, the water outlets of existing vehicle-mounted water dispensers are exposed during use. This is not only unsightly, but also makes the water outlets prone to breakage due to collisions.

[0008] Fourth, existing heating water tanks are limited by structural constraints, making them relatively complex. They are particularly unsuitable for installation and use in the small space of the driver's cab, and are prone to problems such as adding too much water or not adding enough water, which affects the convenience of drinking.

[0009] Fifth, the existing coffee module on in-vehicle water dispensers has a complex connection structure between the water outlet and the main body of the dispenser when the coffee capsule box assembly is removed for inserting or removing coffee capsules, making disassembly and assembly cumbersome and reducing the ease of use.

[0010] Sixth, because the coffee capsule box needs to be disassembled and reassembled frequently, leakage is likely to occur between the water inlet component and the water inlet of the coffee capsule box, affecting the cleanliness of the vehicle interior.

[0011] Seventh, when existing vehicle-mounted water dispensers are not used for a long time, their internal water storage tanks need to be cleaned. The cleaned liquid is easy to discharge along the water outlet, which can easily cause secondary pollution to the water outlet.

[0012] As can be seen from the above, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0069] As an optimized solution, the outlet end of the pressure relief valve is connected to a waste liquid box.

[0070] Compared with the prior art, the beneficial effects of the present invention are: (1) When water is supplied by the water tank, the bottom insert is inserted into the sealing ring in the inlet connector and the sealing ring is press-fitted to achieve a sealing and fixing effect. When bottled water is needed for water supply, connect the bottle mouth thread groove of the bottled water connector to the bottle mouth thread of the bottled water, then separate the water tank from the inlet connector, insert the insert of the bottled water connector into the sealing ring in the inlet connector, and press the sealing ring to achieve a sealing and fixing effect, so as to realize the water supply operation using bottled water. Two water supply methods can be selected according to actual use, which is convenient and quick. In addition, when the water tank is not used for a long time and needs to be disassembled for maintenance, bottled water can be used for water supply to compensate for the time spent cleaning and maintaining the water tank. (2) By setting up a telescopic structure, the drive motor can use gears and racks to drive the support tube to move when in use, thereby driving the water outlet shell to extend out from inside the water dispenser box; when not in use, the drive motor drives the water outlet shell to move inside the water dispenser box, thus hiding the water outlet shell. This not only avoids accidental damage when it extends to the outside, but also reduces space occupation and improves aesthetics. Several positioning protrusions are provided around the inner wall of the track hole. The protrusions and positioning strips rub against the outer wall of the support guide tube, thereby reducing the contact area with the support guide tube, reducing the friction noise between the support guide tube and the track hole when it moves, and improving the mobility during the sliding process. A rectangular guide groove is provided at the bottom of the track hole, and a rectangular guide block is fixedly connected to the lower end of the support tube and slidably constrained in the rectangular guide groove. This enables precise guidance of the support tube during movement, ensures the stability of the water outlet shell during expansion and contraction, and improves the quality of use. (3) The heating body is fixed in a U-shape on the bottom surface of the encapsulated steel ladle, which increases the contact area with the encapsulated steel ladle and improves the heating efficiency without affecting the arrangement of other structures at the bottom; By fixing the temperature switch to the internal area surrounded by the heating body, accurate detection of the heating temperature can be achieved, further improving the accuracy of temperature control. By installing high-level and low-level sensors inside the sealed steel ladle, the water storage capacity of the sealed steel ladle can be measured to prevent the phenomenon of adding too much or too little water. By optimizing the position of each structure, the steel ladle is made smaller and easier to install and use in a cramped cab space. (4) By vertically setting a water outlet at the outlet end of the capsule box body, the outer wall of the water outlet is fitted with rubber rings in parallel from top to bottom, and the module bracket is provided with an insertion channel that matches the water outlet. The water outlet and the insertion channel are sealed by the rubber rings arranged in parallel, which can realize the quick combination or separation of the two, simplifying the connection structure between the capsule box body and the module bracket, making disassembly and assembly quick, and improving the convenience of use; When the clamping bracket is pressed against the outer wall of the capsule box body, the outlet end of the water inlet pipe assembly is connected to the inlet end of the capsule box body through the sealing element, which can effectively prevent leakage between the water inlet assembly and the water inlet of the coffee capsule box, ensuring the cleanliness of the vehicle interior. (5) When water is being discharged normally, the water pump works to pump the liquid into the heating module for heating, and then the liquid is discharged through the normal water discharge unit; When coffee needs to be brewed, the high-pressure pump works to pressurize the water. The pressurized water is heated by the heating module and then enters the coffee brewing unit to brew the coffee, thus producing coffee. It integrates normal water dispensing and coffee brewing, allowing users to choose between dispensing hot water or brewing coffee, thus expanding its application range. Because the inlet is connected to the water tank, when the water tank needs to be cleaned, the cleaning water can be discharged directly from the pressure relief valve by manually opening it, without having to pass through the coffee brewing unit or the normal water outlet unit again, thus avoiding secondary pollution of the water outlet and making it convenient and quick. (6) Integrating the above-mentioned functions into one, it not only has a simpler structure, but also a more compact layout between the components, making it more suitable for use in the narrow space inside the driver's cab.

[0130] The outlet end of the pressure relief valve 72 is connected to the waste liquid box 73.

[0131] The working principle of this device is as follows: (1) When water is supplied by water tank 4, the bottom insert 9 is inserted into the sealing ring 2 in the inlet connector 1 and the sealing ring 2 is press-fitted to achieve a sealing and fixing effect. When bottled water is needed for water supply, the bottle mouth thread groove 14 of the bottled water connector 3 is connected to the bottle mouth thread of the bottled water. Then, the water tank 4 is separated from the inlet connector 1, and the insert tube 9 of the bottled water connector 3 is inserted into the sealing ring 2 in the inlet connector 1. The sealing ring 2 is press-fitted to achieve a sealing and fixing effect, so as to realize the water supply operation using bottled water. Two water supply methods can be selected according to actual use, which is convenient and quick. In addition, when the water tank 4 is not used for a long time and is disassembled for maintenance, bottled water can be used for water supply to compensate for the time spent cleaning and maintaining the water tank 4. (2) By setting up a telescopic structure, when in use, the drive motor 27 uses the gear 28 and rack 33 to drive the support tube 29 to move, thereby driving the water outlet shell 22 to extend out from inside the water dispenser box; when not in use, the drive motor 27 drives the water outlet shell 22 to move inside the water dispenser box, thereby hiding the water outlet shell 22. This not only avoids accidental damage when it extends to the outside, but also reduces space occupation and improves aesthetics. Several positioning protrusions are provided around the inner wall of the track hole 30. The protrusions and positioning strips rub against the outer wall of the support guide tube 29 to reduce the contact area with the support guide tube 29, reduce the friction noise between the support guide tube 29 and the track hole 30 when it moves, and improve the mobility during the sliding process. A rectangular guide groove 31 is provided at the bottom of the track hole 30, and a rectangular guide block 32 is fixedly connected to the lower end of the support guide tube 29 and slidably constrained within the rectangular guide groove 31. This enables precise guidance of the support guide tube 29 during its movement, ensures the stability of the water outlet shell 22 during its extension and retraction, and improves the quality of use. (3) The heating body 42 is fixed in a U-shape on the bottom surface of the encapsulated steel ladle 44, which increases the contact area with the encapsulated steel ladle 44 and improves the heating efficiency, while not affecting the arrangement of other structures at the bottom; By fixing the temperature switch 43 to the internal area surrounded by the heating body 42, accurate detection of the heating temperature can be achieved, further improving the accuracy of temperature control. By installing a high liquid level sensor 40 and a low liquid level sensor 41 inside the encapsulated steel ladle 44, the water storage capacity of the encapsulated steel ladle 44 can be measured to prevent the phenomenon of excessive or insufficient water addition. By optimizing the position of each structure, the steel ladle is made smaller and easier to install and use in a cramped cab space. (4) A water outlet 55 is vertically installed at the outlet end of the capsule box body 59. The outer wall of the water outlet 55 is fitted with rubber rings 56 in parallel from top to bottom. The module bracket 58 is provided with an insertion channel 57 that matches the water outlet 55. The water outlet 55 and the insertion channel 57 are sealed by the rubber rings 56 arranged in parallel. This allows for quick connection or separation of the two, simplifies the connection structure between the capsule box body 59 and the module bracket 58, and makes disassembly and assembly quick, thus improving the convenience of use. When the clamping bracket 46 is pressed against the outer wall of the capsule box body 59, the outlet end of the water inlet pipe assembly 47 is connected to the inlet end of the capsule box body 59 through the sealing element, which can effectively prevent leakage between the water inlet assembly and the water inlet of the coffee capsule box 76, and ensure the cleanliness of the vehicle interior. (5) When water is being discharged normally, the water pump 65 works to pump the liquid into the heating module 67 for heating, and then the liquid is discharged through the normal water discharge unit 69. When it is time to brew coffee, the high-pressure pump 64 works to pressurize the water. The pressurized water is heated by the heating module 67 and then enters the coffee brewing unit 70 to brew coffee, thus producing coffee. It integrates normal water dispensing and coffee brewing, allowing users to choose between dispensing hot water or brewing coffee, thus expanding its application range. Because the inlet is connected to the water tank 4, when the water tank 4 needs to be cleaned, the cleaning water can be discharged directly from the pressure relief valve 72 by manually opening it, without having to go through the coffee brewing unit 70 or the normal water outlet unit 69 again, thus overcoming secondary pollution to the water outlet and making it convenient and quick. (6) Integrating the above-mentioned functions into one, it not only has a simpler structure, but also a more compact layout between the components, making it more suitable for use in the narrow space inside the driver's cab.
