Description

Technical Field

[0001] The utility model relates to the technical field of water heaters, in particular to a portable water heater. Background Art

[0002] Portable water heaters are widely popular for their convenience and practicality in outdoor activities, especially in scenarios such as long-distance travel, camping, and wilderness exploration. These water heaters can usually be charged via a vehicle's cigarette lighter, allowing for easy access to hot water on the go. However, portable water heaters currently on the market face a key issue: their charging voltage is typically fixed at 12V, primarily to accommodate the 9V-17V range of cigarette lighters in most cars. However, this design ignores the 18V-32V range of cigarette lighters in heavy vehicles such as trucks and pickups, especially those with common 24V systems.

[0003] For users who own a truck or pickup truck, they cannot directly charge the portable water heater using the vehicle's cigarette lighter because the water heater's charging circuit may not be able to withstand voltages higher than 12V. If the user attempts to charge the portable water heater directly using a 24V vehicle cigarette lighter without a step-down module, the high voltage is likely to damage the water heater's main control module or other key components, which will not only result in financial losses but also affect the smooth progress of the trip.

[0004] To solve this problem, users need to carry an additional step-down module and manually connect it each time they charge, which not only increases the complexity of the operation, but may also cause damage to the device due to incorrect connection or operation. Utility Model Content

[0029] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0032] See Figure 1 The utility model discloses a portable water heater, which includes a body 1 and a voltage conversion component 2. The body 1 is provided with a power supply access terminal 11. Figure 2 The voltage conversion component 2 is arranged in the body 1. For details, see Figure 6 The voltage conversion component 2 includes a mounting shell 21 and a PCB board 22 . The PCB board 22 is connected to the mounting shell 21 , and the PCB board 22 is electrically connected to the power input terminal 11 .

[0033] Based on this structure, when using the portable water heater of the present invention, the power supply terminal 11 can be connected to the vehicle cigarette lighter or other suitable power socket via a wire. The power supply terminal 11 is tightly connected to the vehicle cigarette lighter socket to ensure stable current transmission. In this way, the water heater can obtain power from the vehicle's power system.

[0034] When power input terminal 11 receives electrical energy, the current is transmitted through the wires to voltage conversion assembly 2. PCB board 22 in voltage conversion assembly 2 begins to operate, detecting and converting the received voltage, converting the incoming power voltage to a standard voltage compatible with the water heater. The stable electrical energy after voltage conversion is then transmitted to the water heater's battery 10 or an electrical device (such as the ignition device 3) to charge the water heater.

[0035] As a result, the portable water heater of the present invention is compatible with the voltage range (9V-32V) of vehicle cigarette lighters of different vehicle models through the voltage conversion component 2, thereby greatly improving the versatility and practicality of the water heater. Furthermore, because the voltage conversion component 2 is built into the water heater body 1, users do not need to carry additional step-down modules or other equipment and can directly use the water heater with the vehicle cigarette lighter of different vehicle models, greatly improving ease of use. The voltage conversion component 2 can quickly and accurately convert the input voltage into the stable charging voltage required by the water heater, thereby improving charging efficiency.

[0036] It should be noted that the voltage conversion component 2 of the present application can be a DC-DC converter, a switching regulator or a power management chip in the prior art.

[0037] Furthermore, an adhesive layer is provided between the PCB board 22 and the mounting shell 21 , and the PCB board 22 and the mounting shell 21 are connected by fasteners.

[0038] Based on this structure, during assembly, the PCB 22 is first placed in a predetermined position within the mounting housing 21. Next, a layer of adhesive is applied between the PCB 22 and the mounting housing 21. Fasteners (such as screws and nuts) are then used to securely fasten the PCB 22 to the mounting housing 21, ensuring that it does not shift or loosen during operation.

[0039] Thus, the fasteners securely fasten PCB 22 to mounting housing 21, preventing it from shifting or loosening during operation, thereby ensuring the proper functioning of the water heater. The adhesive layer not only strengthens the connection between PCB 22 and mounting housing 21 but also provides waterproof, moisture-proof, and dust-proof properties, protecting PCB 22 from environmental influences and extending its service life.

[0040] Furthermore, the body 1 includes a frame 12 and a housing 13, and the housing 13 is installed at the front end of the frame 12. The power supply terminal 11 is provided on the housing 13. Figure 4 , the inner side of the housing 13 is provided with a connecting seat, see Figure 5 A mounting seat 23 is provided on the mounting shell 21, and the connecting seat is detachably connected to the mounting seat 23.

[0041] Based on this structure, during assembly, the mounting base 23 on the mounting shell 21 can be aligned with the connecting base inside the face shell 13. Then, the connecting base and the mounting base 23 are firmly connected together using appropriate connection methods (such as screws, snaps, etc.) to ensure that the voltage conversion component 2 can be stably fixed in the body 1.

[0042] The power supply port 11 is located on the housing 13, making it easy for the user to connect to an external power source. During use, the user connects the water heater's power supply port 11 to the vehicle's cigarette lighter or other suitable power outlet. After confirming that the power connection is stable, the user turns on the water heater's power switch. This activates the voltage conversion component 2, which converts the external power supply voltage to the stable charging voltage required by the water heater.

[0043] Furthermore, a connecting hole 14 is provided on the connecting seat, see Figure 5 The mounting seat 23 includes a mounting plate, and a mounting hole 24 is provided on the mounting plate, wherein the mounting hole 24 is connected to the connecting hole 14 through a fastener.

[0044] Thus, the connection holes 14 on the connector and the mounting holes 24 on the mounting base 23 are connected by fasteners (such as screws, nuts, etc.), ensuring that the voltage conversion assembly 2 is firmly fixed in the body 1, preventing displacement or loosening during operation. This also ensures that the PCB board 22 is stably connected to the power supply input terminal 11 via the wire, preventing the wiring from loosening. At the same time, the detachable connection between the connector and the mounting base 23 makes assembly and maintenance of the water heater more convenient.

[0045] Further, see Figure 3 A controller 20 is provided in the body 1 , and the controller 20 is electrically connected to the PCB board 22 .

[0046] Specifically, the controller 20 may be a control circuit board, a CPU, etc. in the prior art.

[0047] During use, the water heater's power switch is turned on, and controller 20 begins operating, establishing an electrical connection with PCB 22 of voltage conversion assembly 2. Controller 20 receives the voltage from an external power source and, through voltage conversion assembly 2, converts it into the stable charging voltage required by the water heater. During this conversion process, controller 20 monitors the operating status of voltage conversion assembly 2 in real time to ensure proper operation.

[0048] Thus, by being electrically connected to the PCB board 22 of the voltage conversion component 2, the controller 20 can monitor the working status of the voltage conversion component 2 in real time and adjust its output voltage and current as needed to ensure stable operation of the water heater.

[0049] Further, see Figure 7 A battery 10 is also provided in the body 1 , and the battery 10 is electrically connected to the controller 20 .

[0050] Based on this structure, during assembly, the battery 10 needs to be correctly installed in the battery compartment inside the water heater body 1, and the positive and negative poles of the battery 10 need to be correctly aligned with the electrodes in the battery compartment. Before use, if the battery 10 is low on power, the user can charge the battery 10 through an external power source (such as a home charger or a car charger).

[0051] When the battery 10 is fully charged, the water heater can be turned on, and the controller 20 begins operation. The controller 20 first checks whether the voltage and current of the battery 10 are stable and determines whether to supply power. If the battery 10 voltage and current are normal, the controller 20 executes the entire system startup procedure.

[0052] During the startup process, the controller 20 sends a control signal to the voltage conversion component 2 to adjust the input voltage to a range suitable for the water heater. At the same time, the controller 20 also sends an ignition signal to the ignition device 3 to start the ignition process of the water heater.

[0053] Therefore, by providing the battery 10, the water heater is no longer dependent on an external power socket, and the user can use the water heater in an outdoor environment without a power socket, thereby improving its portability and flexibility.

[0054] Further, see Figure 3 and Figure 7 An ignition device 3 is also provided in the engine body 1, and the ignition device 3 is electrically connected to the controller 20. The controller 20 is used to control the start and stop of the ignition device 3.

[0055] Specifically, the ignition device 3 typically consists of an ignition needle, a high-voltage coil (pulse igniter), and a solenoid valve. The ignition needle is located near the burner. When the high-voltage coil is energized, a high voltage is generated on the ignition needle, causing a spark. The solenoid valve is responsible for controlling the supply of gas. When the ignition device 3 is operating, the controller 20 controls the solenoid valve to open, allowing gas to flow into the burner.

[0056] Thus, through the electrical connection with the controller 20 , the ignition device 3 can receive the control signal, achieve accurate start and stop control, and ensure the stable operation of the equipment.

[0057] Further, see Figure 7 A combustion chamber 19 and a gas pipeline 18 are provided inside the engine body 1, and a gas tank 17 is provided outside the engine body 1. The two ends of the gas pipeline 18 are respectively connected to the combustion chamber 19 and the gas tank 17; the ignition device 3 is provided in the combustion chamber 19.

[0058] Based on this structure, first properly connect the gas tank 17 to the gas pipe 18 outside the water heater body 1, ensuring a leak-proof connection. Open the valve on the gas tank 17, and gas begins to flow through the gas pipe 18 to the combustion chamber 19. The controller 20 then activates, sending an ignition signal to the ignition device 3. The ignition needle inside the ignition device 3 generates an electric spark under the action of the high-voltage coil. Simultaneously, the controller 20 controls the solenoid valve to open, allowing gas to flow into the combustion chamber 19. The electric spark ignites the gas-air mixture, initiating combustion in the combustion chamber 19 and generating heat.

[0059] Therefore, through the gas supply of the gas tank 17 and the power supply of the vehicle cigarette lighter, combined with the adaptation function of the voltage conversion component 2, the water heater can provide hot water efficiently and stably in the outdoor environment to meet the user's hot water needs.

[0060] Further, see Figure 2 and Figure 3 The frame 12 is provided with a mounting cavity having a mounting opening. In addition, a side sealing plate 15 is detachably connected to the side of the frame 12. The side sealing plate 15 is used to cover the mounting opening when the frame 12 is installed, and the side sealing plate 15 is used to open the mounting opening after removal.

[0061] Based on this structure, when the components in the installation cavity need to be assembled, repaired or replaced, the side sealing plate 15 can be removed from the side of the frame 12. At this time, the installation port is opened, and the installation cavity can be easily entered from the side to operate the internal components.

[0062] The side sealing plate 15 may be connected to the frame 12 by fasteners such as screws and bolts, or may be detachably connected to the frame 12 by a snap-fit ​​structure.

[0063] It should be noted that since the voltage conversion component 2 is connected to the face shell 13, and the PCB board 22 is connected to the power access terminal 11 and the controller 20 components in the installation cavity through wires, by disassembling the side sealing plate 15, it is possible to avoid pulling the line when removing the face shell 13, thereby protecting the integrity and safety of the line and preventing equipment failure or safety hazards caused by damage to the line.

[0064] Furthermore, a handle 16 is provided on the top of the frame 12 , and the handle 16 is used for a person to hold to move the body 1 .

[0065] Thus, the handle 16 allows the user to easily hold and move the entire device 1, making it more convenient and quicker to adjust the position indoors or carry and transfer it outdoors. The handle 16 is located on the top of the frame 12, which makes it easier for the user to maintain the balance and stability of the device 1 when moving it, preventing damage caused by tilting or rolling.

[0066] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
