Detailed Implementation

[0051] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0052] Reference Figures 1-20 A vehicle-mounted liquid heating device for automobiles includes a cup body 1, a water outlet 6, a liquid heating component 18 with a liquid heating channel 69, and a water pump 17. The liquid heating component 18 is assembled inside the cup body 1, the water outlet 6 is assembled and connected to the cup body 1, the liquid inlet of the water pump 17 is connected to a water source, the liquid outlet of the water pump 17 is connected to the water inlet 19 of the liquid heating component 18, and the liquid outlet 20 of the liquid heating component 18 is connected to the water outlet 9 of the water outlet 6.

[0053] When using this device, connect the inlet of the water pump 17 to the water source and power the liquid heating component 18. When you want to drink water, start the water pump 17 and directly pump the liquid to the liquid heating component 18. After the liquid is heated through the liquid heating channel 6, it is discharged from the outlet 9 of the outlet head 6. In this way, users can conveniently obtain hot water in the vehicle. This device allows drivers or passengers to obtain the amount of hot water they need and avoids the need to repeatedly heat the water.

[0054] As one implementation method, refer to Figure 6 , Figure 7 , Figure 13 The heating device includes a water tank 5, which is assembled or integrally formed with the cup body 1. The inlet end of the water pump 17 is connected to the water tank 5. The water tank 5 includes an open water tank body 22, and the water tank body 22 is detachably fitted with a water tank cover 13 at the open end.

[0055] The water tank body 22 can be detachably assembled onto the cup body 1, which facilitates adding water or cleaning the water tank, and also reduces the overall manufacturing difficulty.

[0056] When in use, liquid is filled into the water tank 5, and the liquid in the water tank 5 is directly pumped by the water pump 17 and delivered to the liquid heating component 18. Since the device has its own water tank 5, the user does not need to add water frequently and avoids repeated heating of water.

[0057] In one embodiment, the water tank body 22 and the cup body 1 are detachably assembled, the water tank cover 13 is provided with a one-way air inlet valve 34 that allows air to enter the water tank body 22, and / or the water tank cover 13 is provided with a breathable membrane 35 that allows air to pass through but not water.

[0058] The water tank 5 of this device adopts a closed structure. The closed water tank 5 means that there will be no leakage when the water tank is tilted or shaken, but it does not mean that it is completely sealed. For example, an air pressure balancing device can be set to balance the pressure difference between the water tank 5 and the external environment. For example, a one-way air inlet valve 34 can be set. This valve body is to ensure that the pressure inside the water tank 5 reaches balance quickly when the water pump is pumping water. A breathable membrane 35 can also be set. This breathable membrane 35 allows air to pass through, but liquid cannot pass through. This setting is to prevent the pressure inside the water tank 5 from being too high or too low in hot or cold weather when it is not in use.

[0059] refer to Figure 7 , Figure 13 The water tank body 22 has a concave second mating surface 23 on its side, and the cup body 1 has a first mating surface 21 that can at least partially fit the second mating surface 23.

[0060] The two mating surfaces 23 make the water tank 5 and the cup body 1 fit more tightly, and the curved surface can provide multi-directional limiting function, improving the stability of the connection between the water tank and the cup body.

[0061] And / or the side of the water tank body 22 and the cup body 1 have a strip groove 24, and the other has a strip protrusion 54. The strip protrusion 54 can be inserted into the strip groove 24 from bottom to top, and the two are circumferentially limited and matched.

[0062] During installation, the water tank body 22 is assembled onto the cup body 1 from top to bottom, so that the strip groove 24 and the strip protrusion 54 achieve circumferential positioning, avoid left and right swaying, and further improve the stability of the connection between the two.

[0063] refer to Figure 9 And / or the cup body 1 has a bottom plate portion 52, one of the bottom plate portion 52 and the bottom of the water tank body 22 has a locking post 71, and the other has a locking groove 59, and the locking post 71 and the locking groove 59 are connected by a snap fastener;

[0064] The water tank body 22 is assembled onto the cup body 1 from top to bottom, so that the locking post 71 is engaged in the locking groove 59, thereby achieving all-round positioning of the water tank body 22 and the cup body 1, ensuring the stability of the connection, and ensuring that the water tank will not detach from the cup body during driving.

[0065] refer to Figures 8-10 The water tank cover 13 includes a first cover body 27 and a second cover body 33 that are fixedly assembled. Two opposing hand-operated fasteners 28 are located between the first cover body 27 and the second cover body 33 and are slidably connected. The sliding direction of the hand-operated fasteners 28 is arranged radially along the water tank body 22. A first thrust spring 26 is provided between the adjacent sides of the two hand-operated fasteners 28. The end of the hand-operated fasteners 28 away from the first thrust spring has an insertion part 30. The inner wall of the water tank body 22 has a slot 25 for the insertion part 30 to be inserted. A first sealing ring 31 is sandwiched between the first cover body 27 and the second cover body 33. The outer periphery of the first sealing ring 31 abuts against the inner wall of the water tank body 22.

[0066] The first sealing ring 31 seals the water tank cap 13 to the water tank body 22 to prevent leakage. When it is necessary to open the water tank cap 13, pinch the two hand-clamping buckles 28 with two fingers respectively and apply pressure inward to overcome the elastic force of the first thrust spring 26, so that the insertion part 30 of the hand-clamping buckle 28 disengages from the slot 25, and the water tank cap 13 can be separated from the water tank body 22.

[0067] This device is equipped with a water tank 5 with a snap-lock opening and closing function, which facilitates water filling and cleaning, and meets the needs of driving while preventing water leakage due to vehicle shaking.

[0068] and / or reference Figure 4 , Figure 12 The bottom of the water tank body 22 is equipped with a self-locking drainage component 15, which includes a column component 41 that penetrates the bottom plate of the water tank body 22. The column component 41 has a first flow gap 44 around its periphery. A sealing ring 42 is installed at the top of the column component 41 and is located on the upper side of the bottom plate of the water tank body 22. A second thrust spring 43 is installed between the bottom end of the column component 41 and the bottom plate of the water tank body 22. The cup body 1 is provided with a push rod 46 that can lift the column component 41.

[0069] In its natural state, under the elastic action of the second thrust spring 43, the sealing ring 42 is pressed against the upper side of the bottom plate of the water tank body 22, sealing the through hole of the bottom plate of the water tank body 22. After the water tank is installed into the cup body, the top rod 46 of the cup body 1 pushes the column part 41 upward, causing the column part 41 to move the sealing ring 42 away from the bottom plate of the water tank body 22, and the water in the water tank flows out through the first flow gap 44.

[0070] To facilitate water introduction into the water pump, refer to... Figure 14 A drain seat 45 is fixed on a bracket 50 inside the cup body 1. The drain seat 45 has a cavity and a drain section 51 connected to the cavity. A second sealing ring 47 is installed on the edge of the cavity. The second sealing ring 47 can seal with the first cylindrical part 48 at the bottom of the water tank body 22 and with the second cylindrical part 49 at the bottom of the base plate 52. A push rod 46 is provided inside the drain seat 45. When the water tank is installed into the cup body, the first cylindrical part 48 at the bottom of the water tank body 22 is inserted into the cavity of the drain seat 45. At the same time, the push rod 46 pushes the column part 41 upward. The water in the water tank flows to the drain section 51 through the first flow gap 44 and then is connected to the water pump through the connecting pipe.

[0071] One embodiment of the liquid heating assembly 18, see reference. Figure 19 The liquid heating assembly 18 includes a nanofilm electric heating tube assembly 66, which includes a tube base 661. Both ends of the tube base are sealed with joints 63. Each joint 63 has a liquid flow channel 64, and the liquid flow channel 64 and the inner cavity of the tube base at least partially form a liquid heating flow channel 69. Heating is achieved by the nanofilm electric heating tube assembly 66 heating the liquid in the liquid heating flow channel 69. The joints 63 sealed at both ends of the tube base are to prevent leakage and improve safety.

[0072] To provide heating speed, a core assembly is provided inside the tube base. The core assembly includes an inner cylinder 68 and plugs 70 sealing both ends of the inner cylinder 68. The plugs 70 are positioned between the inner cylinder 68 and the connector 63 and have a second flow gap 65. The space between the outer periphery of the inner cylinder 68 and the inner periphery of the tube base is at least a part of the liquid heating channel 69. The core assembly enables the liquid to exchange heat with the tube base better.

[0073] As one implementation method, if there is water inside the liquid heating channel 69 when it is cold, it may freeze, which will increase the internal pressure of the tube base. The inner cylinder 68 and the tube base of this device are both made of metal. The wall thickness of the inner cylinder 68 is smaller than the wall thickness of the tube base. The pressure generated when freezing causes the thinner inner cylinder 68 to deform, for example, through elastic deformation, to avoid damaging the tube base.

[0074] A flow-deflecting element 67, such as a flow-deflecting spring, is provided between the inner cylinder 68 and the tube base;

[0075] The and / or nanofilm electric heating tube assembly 66 includes a tube substrate, a first insulating layer attached to the outer wall of the tube substrate, and a second insulating layer attached to the outer wall of the first insulating layer, wherein at least two spaced electrode layers are attached to the second insulating layer.

[0076] Multiple insulation layers are set to improve electrical safety. The first and second insulation layers can be made of the same material or different materials.

[0077] The liquid heating assembly 18 includes a housing 61, which includes two half-shells 611 and two end plates 62. The mating surfaces of the two half-shells 611 are arranged along the axial direction of the tube base. The nanofilm heating tube assembly 66 is at least partially located between the two half-shells 611. The two end plates 62 are located at both ends of the half-shells 611 respectively, and each end plate 62 is fixedly assembled with the two half-shells 611. The nanofilm heating tube assembly 66 is fixed by the two half-shells 611, and then the two half-shells 611 are fixed by the two end plates 62. The assembly is simple and convenient.

[0078] In one embodiment, the liquid heating assembly 18 includes a control board 60 and an electronic board 11. The control board 60 and the electronic board 11 are electrically connected. The control board 60 is installed inside the cup body 1, and the electronic board 11 is installed inside the water outlet 6. The electronic board 11 is electrically connected to a water outlet control component 8 and / or a child lock 7. The control board 60 is electrically connected to a pressure sensor and / or a vibration sensor.

[0079] By detecting ambient air pressure through an air pressure sensor, the heating effect can be better handled by different atmospheric pressures. The vibration sensor senses whether the operating environment is stable and controls whether the whole machine can operate under unstable conditions such as obvious vibration / tilt / acceleration / deceleration / bumps.

[0080] When using this device, first unlock the machine using the child lock 7, then control the water temperature using the water outlet control component 8. For example, turn the control knob to adjust the water temperature, then press the knob to control the water flow, and release the knob to disconnect the water supply.

[0081] refer to Figure 11 The water outlet 6 includes a cover 10 and a water outlet 12 located at least partially inside the cover 10. The water outlet 12 is connected to the drain end 20 of the liquid heating assembly 18, and the water outlet 9 is located at the downstream end of the water outlet 12.

[0082] The cover 10 is eccentrically rotatably connected to the cup body 1 via a rotating connecting part 14. The rotating connecting part 14 includes a limiting ring 38 and a first screw 39. The cover 10 has a limiting step 40 offset from its axis. The cup body 1 has a mounting base 36, and the mounting base 36 has a connecting part 37. The limiting ring 38 is limited at the upper part of the limiting step 40. The first screw 39 partially passes through the limiting ring 38 and connects to the connecting part 37. The limiting step 40 is at least partially sandwiched between the limiting ring 38 and the mounting base 36. The cover 10 and the mounting base 36 are rotatably connected by the limiting ring 38. When not in use, the water outlet 6 is rotated to close the water outlet 9, and the entire device is cylindrical.

[0083] To facilitate assembly of the device, the cup body 1 includes a first shell 2 and a second shell 3. The first shell 2 and the second shell 3 are assembled together, and there is a receiving cavity 72 between them. The water tank 5 is assembled and connected to the second shell 3. A bracket 50 is fixedly installed in the receiving cavity 72. The water pump 17 and the liquid heating component 18 are both fixedly assembled with the bracket 50 vertically. The bracket 50 is assembled and connected to a control board 60 that is electrically connected to the liquid heating component 18 and the water pump 17, a power connection part 16 that is electrically connected to the control board 60, and a silicon controlled rectifier 55. A heat-conducting component 56 is fixedly installed on the bracket 50. The silicon controlled rectifier 55 is fixed on the heat-conducting component 56. A heat-conducting pipe 73 is installed on the heat-conducting component 56. One end of the heat-conducting pipe 73 is connected to the water tank 5, and the other end of the heat-conducting pipe 73 is connected to the liquid inlet of the water pump 17.

[0084] First, assemble all the components onto the bracket 50, and then fix the bracket 50 between the first housing 2 and the second housing 3 to reduce assembly difficulty;

[0085] And / or the bottom of the cup body 1 has a placement seat 4 adapted to the car cup holder, for example, the first housing 2 is set as a conical structure that can be inserted into the car cup holder;

[0086] And / or the heating device is cylindrical in shape.

[0087] When using this device, fill the water tank 5 with water, then open the child lock 7, adjust the water temperature through the water outlet control component 8, and then press the water outlet control component 8 to dispense water. The water pump draws water from the water tank 5, and the water flows through the first flow gap 44 into the drain seat 45. Then, it flows through the drain section 51 of the drain seat 45 into the flow meter 53 for measurement, and then into the heat conduction pipe 73. The heat conduction pipe 73 absorbs the temperature inside the device, cools down, and preheats and recovers the water. Then, it flows through the first three-way component 57 into the water pump. The first three-way component 57 can be used to install the first temperature sensor. Then, the water pump sends the water into the inlet 19 of the liquid heating component 18. The water is heated in the liquid heating channel 69 and discharged from the drain end 20. Then, it enters the second three-way component 58, then the water outlet 12, and finally is discharged from the water outlet 9. The second three-way component 58 can be used to install the second temperature sensor. After use, rotate the water outlet head 6 back to its original position. The entire device has a cylindrical structure.

[0088] A control system for an on-board liquid heating device includes a main control module, an environmental detection module electrically connected to the main control module, and a heating module. The heating module can adjust the heating power according to the detection value of the environmental detection module.

[0089] When this heating device is used in a car, the vibrations of the car can cause the liquid inside the heating tube to slosh around, leading to dry burning and potential damage. The environmental detection module can effectively solve this problem. When the car is vibrating, the heating module reduces its power or stops heating altogether. When the car is moving smoothly, the heating module will operate normally.

[0090] In one implementation, the environmental detection module includes a position detection unit, which is at least used to detect the bumps of the vehicle. The main control module controls the power of the heating module according to the degree of vehicle bumps detected by the position detection unit. In one embodiment, the position detection unit may be a gyroscope.

[0091] In one implementation, the environmental detection module includes an air pressure detection unit, which is used to detect at least the ambient air pressure of the vehicle-mounted liquid heating device. The main control module controls the heating power of the heating module based on the ambient air pressure detected by the air pressure detection unit.

[0092] Due to the differences in the driving environment of automobiles, the boiling point of liquids is different when the automobile is in different air pressure environments. By detecting the ambient air pressure through the air pressure detection unit, the boiling point of the liquid can be determined, and the heating power of the heating module can be adjusted according to the boiling point of the liquid.

[0093] In one implementation, the environmental detection module includes a boiling point detection unit, which includes a temperature detection unit. The temperature detection unit is used to detect the liquid temperature inside the vehicle-mounted liquid heating device. If the detection value of the temperature detection unit remains unchanged during the operation of the vehicle-mounted liquid heating device, it is determined that the liquid inside the vehicle-mounted liquid heating device has reached the boiling point.

[0094] When the vehicle-mounted liquid heating device is working normally, the temperature detection unit continuously detects that the temperature of the heated liquid remains unchanged, indicating that the liquid has reached the boiling point. This allows the heating power of the heating module to be adjusted to prevent the heating module from continuing to heat at high power when the liquid has reached the boiling point.

[0095] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
