The mounting part is fixedly mounted on the heating element, and the reset rod is capable of linear movement relative to the mounting part. The housing includes a cover plate made of a deformable material. When the reset rod pops out, pressing the cover plate can compress the reset rod to move downwards and reset.

[0015] In the aforementioned portable heating device, a mounting plate is detachably provided on the side wall of the housing, and the water inlet connection end and the water outlet connection end are fixedly mounted on the mounting plate. When the housing is fixed to the mounting plate, the housing and the mounting plate are sealed together.

[0016] In the aforementioned portable heating device, the housing is provided with a connection hole, and a sealing part is provided inside the connection hole. The power supply connection part includes a connecting wire, which passes through the connection hole and is sealed to the sealing part.

Detailed Implementation

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0033] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0034] like Figures 1-7 As shown, a portable heating device includes:

[0035] The housing 100 has an installation cavity 101 inside, and a self-priming water pump 102, a control module 103, and a heating element 104 are installed in the installation cavity 101. The self-priming water pump 102, the control module 103, and the heating element 104 are linearly distributed, and the length extension direction of the self-priming water pump 102, the control module 103, and the heating element 104 are parallel. The self-priming water pump 102 is connected to the heating element 104, and the control module 103 is electrically connected to both the heating element 104 and the self-priming water pump 102.

[0036] The water inlet connection 105 is provided on the housing 100 and is connected to the self-priming water pump 102.

[0037] The water outlet connection end 106 is disposed on the housing 100 and connected to the heating element 104;

[0038] The power supply connection part 107 is disposed on the housing 100 and is electrically connected to the control module 103.

[0039] In this embodiment, the portable heating device achieves a more compact overall structure, improves space utilization, reduces equipment size, and facilitates portability and mobile use by linearly arranging the self-priming water pump 102, control module 103, and heating element 104 inside the housing 100. Simultaneously, the device is equipped with independent water inlet connection 105 and water outlet connection 106, enabling convenient connection to an external water source. The self-priming water pump 102 automatically draws water and delivers it to the heating element 104 for rapid heating.

[0040] The control module 103 includes a control circuit board for intelligent control of the heating element 104 and the self-priming water pump 102; the power supply connection 107 extends outside the housing 100 and is compatible with various power input methods, making it convenient for use in outdoor environments.

[0041] Based on the existing technology, the heating element 104 is further designed as a cast aluminum heating element 104. The cast aluminum heating element 104 has a flexible shape and can be adapted to various installation spaces, so that its placement in the housing 100 is not restricted, and the internal structural layout can be further optimized.

[0042] As shown in the figure, in one specific implementation, temperature sensors 200 are fixedly installed on both the inlet connection 105 and the outlet connection 106 to monitor the water flow temperature at the inlet connection 105 and the outlet connection 106. The control module 103 can automatically adjust the power output of the heating element 104 according to the inlet water temperature and the target outlet water temperature to ensure that the outlet water temperature remains stable within the set range, avoiding excessively high or low water temperatures and achieving a constant temperature heating effect. When the temperature sensor 200 detects an abnormal increase in outlet water temperature or a drastic temperature fluctuation, the control module 103 can determine that the equipment is dry-burning, the water flow is obstructed, or the external water source is abnormal, and promptly activate the protection mechanism, such as automatic power-off, alarm prompts, or adjustment of the water pump speed, to ensure the safe operation of the equipment.

[0043] In another embodiment, a water flow rotor 111 can be installed inside the inlet connection 105 and / or the outlet connection 106 to sense water flow velocity and flow rate. Correspondingly, an installation groove 110 is provided on the outer wall of the inlet connection 105 and / or the outlet connection 106, and a water flow sensor is integrated in the installation groove 110. This water flow sensor is electrically connected to the control module 103 and obtains water flow status information in real time by sensing the rotation frequency or magnetic signal changes of the water flow rotor 111. Through the feedback of the water flow sensor, the control module 103 can determine whether there is water flow and whether the water flow is stable, and accordingly realize intelligent start-stop control of "heating when there is flow and power off when there is no flow", further improving safety and energy efficiency.

[0044] Of course, the water flow sensor can also be combined with the temperature measurement data of the temperature sensor 200, and the system can realize multi-parameter linkage control, such as dynamically adjusting the heating power according to the flow rate to ensure that constant temperature hot water can be output under different flow rates.

[0045] Specifically, a first water pipe 300 is detachably installed on the water inlet connection 105, and a second water pipe 301 is detachably installed on the water outlet connection 106. The first water pipe 300 can extend into an external water storage unit (such as a bucket, water tank, or natural water source) to introduce water into the device; the second water pipe 301 is used to deliver heated hot water to the user end. The detachable structure of the water pipes allows users to flexibly install or disassemble them according to actual usage scenarios, and also facilitates transportation and storage, making it particularly suitable for mobile environments such as outdoor activities, camping, and construction sites.

[0046] like Figure 4 As shown, the middle sections of the first water pipe 300 and the second water pipe 301 are fixedly connected. This allows for simultaneous storage of both water pipes, preventing loss, tangling, or confusion when stored separately, thus improving user convenience, especially suitable for outdoor and highly mobile applications. When not in use, they can be wound or folded together and stored on the outside of the device or in the storage slots provided in the housing 100, reducing overall space occupation and further enhancing the device's portability and neat appearance.

[0047] Preferably, the end of the first water pipe 300 is provided with a filter part 302, and the filter part 302 is provided with a first counterweight part 303, and the end of the second water pipe 301 is provided with a second counterweight part 304 or 303, or the end of the second water pipe 301 is provided with a shower head.

[0048] In this embodiment, the function of the filter unit 302 is to perform preliminary filtration of the water entering the heating device, removing impurities, sediment, and other particulate matter from the water to ensure water quality and prevent impurities from entering the heating device and causing blockage or damage to the equipment. The design of the first counterweight 303 allows the filter unit 302 to naturally sink to the bottom of the water storage container during use, maintaining stability even under conditions of water flow disturbance or insufficient water pump suction, ensuring smooth water intake.

[0049] In one application scenario, a second counterweight 304303 is provided at the end of the second water pipe 301. This configuration is suitable for situations where heated water is returned to the original water storage container (such as a bucket). The second counterweight 304303 enables the end of the second water pipe 301 to be stably submerged in the water, preventing the pipe from floating or shifting due to water flow impact or other external forces, thereby ensuring that hot water can be evenly distributed back into the water storage container. This is particularly suitable for scenarios requiring circulating heating or temporary increase in water temperature. Generally, the middle of the first water pipe 300 is fixed to the middle of the second water pipe 301 only when the water in the second water pipe 301 flows back to the original water storage container.

[0050] Another application scenario is that a shower head is installed at the end of the second water pipe 301. In this case, the heated water can be used directly for showering. This design greatly expands the application range of the device, making it not only limited to simple water heating, but also usable as a portable shower system, which is ideal for outdoor camping, fieldwork, or emergency rescue.

[0051] By providing different configuration options for the ends of the first water pipe 300 and the second water pipe 301, this portable heating device can adapt to a variety of usage scenarios, whether for circulating heating or direct use for personal cleaning, thus meeting user needs.

[0052] Specifically, the filter unit 302 includes a filter frame, and a first counterweight 303 is disposed inside the filter frame. The second counterweight 304 is inserted into the end of the second water pipe 301, and a through water flow cavity is disposed inside the second counterweight 304.

[0053] Further, the heating element 104 is provided with a thermostat 203 and a temperature protector 201. The thermostat 203 is capable of self-resetting, and the extreme operating temperature of the thermostat 203 is lower than the extreme operating temperature of the temperature protector 201. The temperature protector 201 includes a reset rod 202 and a mounting part. The mounting part is fixedly mounted on the heating element 104, and the reset rod 202 can move linearly relative to the mounting part. The housing 100 includes a cover plate 108 made of a deformable material. When the reset rod 202 pops out, pressing the cover plate 108 can squeeze the reset rod 202 to move down and reset.

[0054] Thermostat 203, as a primary protection device, has its operating temperature (i.e., disconnection temperature) set lower than that of temperature protector 201. When the temperature of heating element 104 rises to the preset threshold of thermostat 203, thermostat 203 automatically disconnects the circuit and stops heating; after the temperature drops to a safe range, thermostat 203 automatically resets, restoring power and automatically restarting the heating function. This self-reset function is suitable for temperature increases caused by temporary overload or ambient temperature fluctuations.

[0055] Temperature protector 201, as a secondary and ultimate protection device, operates at a higher temperature and is only triggered in extreme cases such as failure of temperature controller 203 or severe overheating (e.g., dry burning, or failure of control module 103). Once the temperature reaches its set limit, temperature protector 201 immediately cuts off the main circuit and, through a mechanical structure, ejects the reset lever 202, entering a "locked" state to prevent the equipment from automatically restarting and ensure user safety.

[0056] The reset lever 202 of the temperature protector 201 can move linearly relative to the mounting part. When it pops out due to overheating, the user does not need to disassemble the device or use tools. Simply press the cover plate 108 made of a deformable material (such as elastic plastic or silicone) on the housing 100 by hand. The deformation of the cover plate 108 will push the reset lever 202 downwards, returning it to its original position, thus completing the manual reset operation. This ingenious design and simple operation greatly improve the user's recovery efficiency after an abnormal situation.

[0057] like Figures 2-5 As shown, preferably, a mounting plate 400 is detachably mounted on the side wall of the housing 100. The inlet connection 105 and the outlet connection 106 are fixedly mounted on the mounting plate 400. When the housing 100 is fixed to the mounting plate 400, the housing 100 and the mounting plate 400 are sealed together. The mounting plate 400 and the housing 100 are detachably connected by screws. At the factory, the manufacturer can pre-determine and install suitable inlet and outlet connections 106 according to the user's specific needs. Simultaneously, the user can also replace these components according to subsequent actual use to meet changing needs, increasing the product's customization and service quality.

[0058] The removable mounting plate 400 design makes the inlet connection 105 and outlet connection 106 easily accessible and maintainable. In case of damage or the need for cleaning or inspection, the mounting plate 400 can be easily removed without extensive disassembly of the entire device, simplifying the maintenance process and reducing maintenance costs.

[0059] Specifically, the housing 100 is provided with a connection hole, and a sealing part 401 is provided in the connection hole to form a good seal between the connecting wire passing through the housing 100 and the housing 100, preventing external dust, moisture or liquid from entering the equipment, thereby improving the overall protection level of the device and ensuring the stable operation of internal electrical components (such as control module 103, heating element 104, self-priming water pump 102, etc.).

[0060] The power supply connection part 107 includes a connecting wire that passes through a connection hole and is sealed to the sealing part 401. A fixing frame 402 is provided on the inner wall of the housing 100, and a mounting frame 403 is provided on the fixing frame 402. When the mounting frame 403 is fixedly connected to the fixing frame 402, a clamping cavity is formed between the fixing frame 402 and the mounting frame 403, and part of the connecting wire is fixed within the clamping cavity. This prevents the wire from shifting or loosening due to vibration, movement, or external pulling.

[0061] Further defining the sealing part 401, it includes a sealing ring, a stop ring 404 is provided inside the connection hole, and an abutment ring 405 is provided on the mounting plate 400. The abutment ring 405 and the stop ring 404 clamp and fix the sealing ring. This ensures the stability of the sealing ring and its tight contact with the connection hole and connecting wires, effectively preventing external substances such as moisture and dust from entering the housing 100 and improving the protection level of the equipment.

[0062] The cover plate 108 is detachably connected to the housing 100. When the cover plate 108 is fixed to the housing 100, the cover plate 108 and the housing 100 are sealed together. The detachable design of the cover plate 108 allows users or maintenance personnel to easily open the housing 100 to inspect, repair, or replace internal components (such as the control module 103, heating element 104, thermostat 203, temperature protector 201, etc.) without destructive operation, significantly improving maintenance efficiency.

[0063] With the cover plate 108 and housing 100 fixed in the same position, they form a sealed connection, effectively preventing external moisture, dust, mud, and other contaminants from entering the installation cavity 101. This sealing structure, together with the sealing part 401 at the aforementioned connection hole, improves the overall waterproof and dustproof level of the device, ensuring stable and safe operation of the equipment in complex environments such as outdoor humidity, rain, and construction sites.

[0064] The cover plate 108 is equipped with a display screen 500 and control buttons. The display screen 500 and control buttons are electrically connected to the control module 103. The display screen 500 is sealed to the cover plate 108.

[0065] The display screen 500 is used to display the real-time operating status of the equipment, such as inlet water temperature, outlet water temperature, set temperature, working mode, power status, and fault alarm information; the control buttons allow users to directly perform operations such as power on / off, temperature adjustment, and mode selection. Both are electrically connected to the control module 103 to form a complete local human-machine interaction system, which can complete all operations without relying on external devices, improving user autonomy and convenience.

[0066] The display screen 500 and the cover plate 108 adopt a sealed connection structure (e.g., through rubber sealing rings, waterproof adhesive, or hot-press sealing process), effectively preventing moisture, humidity, dust, etc., from entering the interior of the housing 100 from the edge of the display interface. This significantly improves the environmental adaptability of the device, making it suitable for complex or harsh usage scenarios such as outdoor, humid, and construction sites.

[0067] Specifically, in one embodiment, the display screen 500 includes a mounting cover, and the housing 100 is provided with multiple sealing grooves 109, each containing a sealing ring. When the housing 100 is fixedly connected to the cover plate 108, the mounting cover, and the mounting plate 400, the housing 100 and the corresponding components cooperate to clamp and fix the sealing ring, thereby achieving a reliable sealing connection. This significantly improves the overall waterproof and dustproof capabilities, achieving an IP7 or higher protection rating, suitable for complex environments such as outdoors, humid conditions, and rainy days. The structure is stable, and the sealing is durable and reliable.

[0068] As an alternative or supplementary solution, the housing 100 can also be connected to the cover 108, mounting cover, and mounting plate 400 using sealant (such as silicone, epoxy resin, etc.). This can fill tiny gaps, achieving a seamless seal and further improving airtightness and waterproof performance. A suitable sealing process can be selected based on actual production needs or the usage environment.
