Description

Technical Field

[0001] This invention belongs to the field of outdoor equipment technology, and in particular relates to a multifunctional portable water treatment and heating device. Background Technology

[0002] With the increasing popularity of outdoor activities, people's demands for the quality of outdoor life are rising, especially in scenarios such as outdoor camping and self-driving tours, where the need for safe and convenient water use is particularly prominent. However, existing outdoor water supply equipment generally suffers from many defects and shortcomings.

[0003] First, most outdoor water products on the market are standalone devices with single functions. Users usually need to carry water storage containers (such as water tanks or water bags), water purifiers, heating equipment (such as gas stoves or electric heating equipment), booster pumps, and shower heads, etc. This not only results in a lot of equipment to carry, large overall size and weight, but also makes it extremely inconvenient to store, assemble and manage in the outdoor environment, seriously affecting the convenience of outdoor activities and user experience.

[0004] Secondly, most existing portable water heaters do not have a heating function or only provide a single heating method, lacking efficient integrated heating capabilities. If users need hot water, they often have to rely on additional heating equipment for secondary heating, which is cumbersome, time-consuming, and poses safety hazards. Although some outdoor gas water heaters that provide a single heating method support instant hot water, they are often unable to provide instant hot water in low-temperature or high-altitude areas due to limitations in thermal efficiency specifications. This makes it difficult to provide a continuous and stable hot water supply and fails to meet the comfort needs of outdoor showering and washing.

[0005] In addition, many portable water purifiers use only a single physical filter, which has limited effectiveness in removing deep pollutants such as heavy metals and viruses from the water and cannot ensure absolute drinking water safety. This leads to "water source anxiety" for users when faced with complex outdoor water sources. At the same time, most devices rely on a limited amount of water they carry and lack the ability to directly and safely replenish and deeply purify water from external natural water sources (such as streams and lakes).

[0006] Finally, existing simple outdoor showers or variable frequency booster pumps generally suffer from problems such as insufficient water pressure, unstable water output, and inability to adjust water pressure according to different scenarios. This results in a significant reduction in rinsing and cleaning effects, and fails to provide a comfortable and stable water experience like that at home. Summary of the Invention

[0007] To address the problems existing in the prior art, this invention provides a multifunctional portable water treatment and heating device, which has the advantages of high modular integration, easy portability and storage, dual-mode constant temperature heating, multi-stage deep water purification, dual water source switching, stable and adjustable water pressure, and strong adaptability to multiple scenarios. It solves the problems of existing outdoor water equipment being cumbersome and bulky, complicated to assemble and use, unstable hot water supply, incomplete purification of outdoor water sources, poor water pressure experience, and limited versatility.

[0008] This invention is implemented as follows: a multifunctional portable water treatment and heating device includes a main unit module and a water tank module. The front of the main unit module is equipped with an operation panel and a filter cartridge compartment. The left side of the main unit module is equipped with a gas interface and a water outlet rotary valve. The right side of the main unit module is equipped with a quick-connect water outlet and a battery compartment. The top of the main unit module is equipped with a circulation water inlet and a water inlet. The main unit module is equipped with a variable frequency booster water pump and a gas heating unit. The water outlet rotary valve is used to switch between a preheating circulation water circuit mode, where water flows out from the circulation water inlet into the water tank module to achieve water circulation preheating in the water tank module; or a water circuit mode, where water flows out from the quick-connect water outlet and connects to a water-using tool, which is then filtered, purified, and heated by the variable frequency booster water pump before use.

[0009] As a preferred embodiment of the present invention, it further includes a water tank module and a pull-rod cart. The main unit module is engaged with the inner bottom of the pull-rod cart. The water tank module, water tank module, and main unit module are sequentially engaged and disassembled from top to bottom. The pull-rod cart includes a frame. The inner bottom of the frame has a positioning slot and a positioning hole. The bottom of the main unit module has positioning protrusions fixed at all four corners. The bottom of the main unit module is engaged in the positioning slot, and the positioning protrusions are engaged in the corresponding positioning holes. Side blocks are fixedly connected to both sides of the frame, and the water tank module is located between the side blocks.

[0010] This design facilitates quick assembly and disassembly of the main unit module and the trolley, as well as secure fixation. The side blocks limit the left and right movement of the water tank module, further enhancing the stability of the overall stacked structure. In addition, the elastic straps ensure that the entire equipment is not easily loosened or misaligned during push-pull transport or outdoor bumpy conditions. The integrated load-bearing structure of the trolley eliminates the need to transport individual modules separately, significantly improving the equipment's portability and transportability.

[0011] As a preferred embodiment of the present invention, the bottom of the water tank module is provided with a groove that engages with the top of the main unit module, the top of the water tank module is hinged with a top cover, the top cover is provided with a groove that engages with the bottom of the water tank module, water tank handles are fixed on both sides of the top of the water tank module, and MOLLE tactical mounting plates are installed on both sides of the water tank module.

[0012] With this design, the water tank module is precisely fitted and positioned with the main unit module through the bottom groove, and the stacked structure enables quick assembly and sealing, ensuring the water circuit connection is airtight and preventing leakage. The top cover groove can stably lock the water tank module, ensuring the integrity of the multi-layer module stack. The water tank handle makes it easy to disassemble, move and store the water tank module separately. With the MOLLE tactical mounting plate, various tactical accessories, storage bags, tools, etc. can be attached according to outdoor use needs, greatly expanding the outdoor expansion function and adaptability of the equipment.

[0013] As a preferred embodiment of the present invention, a cover plate is hinged to the top of the sink module, and sink handles are hinged to both sides of the top of the sink module. Folding legs are hinged to the bottom groove of the sink module. When the sink module needs to be used alone, the folding legs can be opened to support the sink module for use, and the cover plate can be opened to support the sink handles for placing items.

[0014] With this design, the sink module can be used independently as an outdoor washbasin or work surface. The folding legs can be stably supported on the top of the water tank module after unfolding, without the need for additional support. The structure is simple and easy to use. The openable cover can close the sink when stored, and when opened, it can be attached to the sink handle to form a temporary storage platform for placing toiletries, kitchen utensils, small tools, etc. It combines storage portability with outdoor practicality, enriching the multi-functional use scenarios of the device.

[0015] As a preferred embodiment of the present invention, a PPC composite filter element is installed in the filter cartridge compartment, and the quick-connect water outlet can also be connected to an external RO reverse osmosis purification module for primary purification and secondary deep purification; the RO reverse osmosis purification module has a built-in reverse osmosis filter element and is equipped with inlet, waste and clean water outlets, which are connected to the quick-connect water outlet via a quick-connect method, and the pressure of the variable frequency booster pump built into the main unit module drives the primary purified water to pass through the RO membrane to complete the deep purification.

[0016] This setup creates a two-stage purification system. The PPC composite filter cartridge completes the first-stage purification of the water, effectively filtering large particles such as sediment, suspended solids, colloids, and insect eggs, thus initially purifying the water quality. A second-stage deep purification is achieved through an external RO reverse osmosis purification module, precisely filtering out tiny harmful substances such as heavy metals, bacteria, viruses, and scale, completely solving the problem of unstable water quality in complex outdoor water sources. The modular quick-connect design allows for easy switching between single-stage and dual-stage purification modes depending on water quality, catering to both ordinary cleaning water and safe drinking water needs, and adapting to various complex outdoor water sources.

[0017] As a preferred embodiment of the present invention, the gas heating unit includes a high-efficiency heat exchanger, an electronically controlled gas valve, and an igniter. Temperature sensors are installed at each of the quick-connect water outlets, and the controller of the operation panel is configured to execute a PID algorithm to adjust the opening of the gas valve.

[0018] This setup enables dual-point temperature sensors to accurately collect inlet and outlet water temperature data in real time, achieving full-process water temperature monitoring. Relying on a PID intelligent algorithm, it dynamically adjusts the opening of the electronically controlled gas valve to precisely control the gas intake. Compared to traditional fixed-fire heating methods, it offers higher temperature regulation accuracy and more stable temperature control. Combined with a high-efficiency heat exchanger, it significantly improves the gas heat utilization rate, effectively addressing the issues of low heating efficiency and large water temperature fluctuations in low-temperature and high-altitude environments. This results in energy-efficient, high-efficiency, and stable hot water output, avoiding the unpleasant experience of sudden temperature changes.

[0019] As a preferred embodiment of the present invention, it also includes an instant heating mode and a preheating mode. In the instant heating mode, the controller on the operation panel detects the water flow signal and triggers ignition, and dynamically adjusts the opening of the gas valve through a PID algorithm to maintain the outlet water temperature. In the preheating mode, the outlet rotary valve switches to the circulation water inlet to form a closed circulation water circuit of water tank-main unit-water tank. The variable frequency booster water pump drives the water flow to circulate and heat. When the temperature reaches the set value, the controller closes the gas valve, and the variable frequency booster water pump continues to run for a set time before stopping.

[0020] With this setting, the dual heating modes are adapted to different outdoor water use scenarios. The instant heating mode heats up as soon as water is turned on and stops heating when water is turned off, without the need for preheating. It is suitable for short-term, sporadic water needs for washing and handwashing, and is energy-saving and efficient. The preheating mode uses a closed-loop water circuit to circulate and heat the entire tank of water evenly, and can achieve a large capacity of constant temperature hot water storage, which is suitable for scenarios with large water consumption such as long-term showers and batch cleaning of kitchen utensils.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention adopts a modular stacked combination structure, which highly integrates water storage, water purification, heating, pressurization and washing functions, replacing traditional outdoor decentralized water tanks, water purifiers, heaters, booster pumps, wash basins and other types of equipment, greatly reducing the size and weight of equipment, making storage and transportation convenient, and completely solving the problems of complicated outdoor equipment and cumbersome assembly, realizing the convenient experience of "one machine in hand, worry-free water use". The device supports two modes: built-in water tank storage and water intake, and direct water intake from external natural water sources. It is equipped with a two-stage purification structure of PPC composite filter and RO reverse osmosis module, which can be adapted to various complex outdoor water sources, comprehensively ensuring water safety and eliminating outdoor water source anxiety. It features dual intelligent heating modes: instant heating and preheating. Combined with precise PID temperature control and a high-efficiency heat exchange structure, it is not limited by low temperature or high altitude environments and can stably output constant temperature hot water, taking into account both immediate water use and large-capacity hot water storage needs. With a built-in variable frequency booster pump, the water pressure is stable and adjustable, solving the problems of insufficient water pressure and fluctuating water output in traditional outdoor equipment, and improving the comfort of outdoor water use. Meanwhile, the equipment modules are flexible in combination, with foldable water tanks, tactical hanging boards, and pull rod transport structures, combining practicality, expandability and portability. It can be fully adapted to various scenarios such as camping, self-driving tours, field operations, and outdoor rescue, and has extremely strong versatility and practicality.

[0024] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0025] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0026] refer to Figures 1 to 13 As shown in the figure, an embodiment of the present invention provides a multifunctional portable water treatment and heating device, including a main unit module 1 and a water tank module 2. The front of the main unit module 1 is equipped with an operation panel 101 and a filter cartridge compartment 102. The left side of the main unit module 1 is equipped with a gas interface 104 and a water outlet rotary valve 111. The right side of the main unit module 1 is equipped with a quick-connect water outlet 106 and a battery compartment 109. The top of the main unit module 1 is provided with a circulation water inlet 107 and a water inlet 108. The inside of the main unit module 1 is equipped with a variable frequency booster water pump 112 and a gas heating unit 113. The water outlet rotary valve 111 is used to switch the preheating circulation water circuit mode, where water flows out from the circulation water inlet 107 into the water tank module 2 to realize the water circulation preheating of the water tank module 2; or in the water circuit mode, water flows out from the quick-connect water outlet 106 and connects to a water-using tool, which is then filtered, purified, and heated by the variable frequency booster water pump 112 before use.

[0027] Specifically, it also includes a water tank module 3 and a pull-rod cart 4. The main unit module 1 is engaged with the inner bottom of the pull-rod cart 4. The water tank module 3, water tank module 2 and main unit module 1 are sequentially engaged and disassembled from top to bottom. The pull-rod cart 4 includes a frame 401. The inner bottom of the frame 401 is provided with a positioning slot 402. The positioning slot 402 is provided with a positioning hole 403. The bottom of the main unit module 1 is fixed with positioning protrusions 114 at each of the four corners. The bottom of the main unit module 1 is engaged in the positioning slot 402, and the positioning protrusions 114 are engaged in the corresponding positioning holes 403. Side blocks 404 are fixedly connected to both sides of the frame 401. The water tank module 2 is located between the side blocks 404.

[0028] The above solution facilitates quick assembly and disassembly and secure fixation of the main unit module 1 and the trolley 4. The side block 404 can limit the left and right movement of the water tank module 2, further improving the stability of the overall stacked structure. At the same time, it can be used with the elastic straps to prevent the entire set of equipment from becoming loose or misaligned during push-pull transportation or outdoor bumpy scenarios. The trolley 4 has an integrated load-bearing structure, eliminating the need to transport each module separately, which greatly improves the equipment's portability and transportation capabilities.

[0029] Specifically, the bottom of the water tank module 2 is embedded with a groove that engages with the top of the main unit module 1, the top of the water tank module 2 is hinged with a top cover 201, the top cover 201 is embedded with a groove that engages with the bottom of the water tank module 3, water tank handles 202 are fixed on both sides of the top of the water tank module 2, and MOLLE tactical mounting plates 203 are installed on both sides of the water tank module 2.

[0030] Using the above solution, the water tank module 2 is precisely fitted and positioned with the main unit module 1 through the bottom groove, and the stacked structure enables quick assembly and sealing, ensuring the sealing of the water circuit connection and preventing water leakage. The groove of the top cover 201 can stably lock the water tank module 3, ensuring the integrity of the multi-layer module stacking. The water tank handle 202 facilitates the individual disassembly, transportation and storage of the water tank module 2. With the MOLLE tactical mounting plate 203, various tactical accessories, storage bags, tools, etc. can be attached according to outdoor use needs, greatly expanding the outdoor expansion function and adaptable scenarios of the equipment.

[0031] Specifically, a cover plate 303 is hinged to the top of the sink module 3, and sink handles 301 are hinged to both sides of the top of the sink module 3. A folding support leg 302 is hinged to the bottom groove of the sink module 3. When the sink module 3 needs to be used alone, the folding support leg 302 can be opened to support the water tank module 2 for use, and the cover plate 303 can be opened to support the sink handle 301 for placing items.

[0032] Using the above solution, the sink module 3 can be used independently as an outdoor washbasin or workbench. The folding legs 302 can be stably supported on the top surface of the water tank module 2 after unfolding, without the need for additional support. The structure is simple and easy to use. The openable cover 303 can close the sink when stored, and when opened, it can be attached to the sink handle 301 to form a temporary storage platform for placing toiletries, kitchen utensils, small tools, etc., taking into account both storage portability and outdoor practicality, enriching the multi-functional use scenarios of the equipment.

[0033] Specifically, the filter cartridge compartment 102 is equipped with a PPC composite filter cartridge 103, and the quick-connect outlet 106 can also be connected to an external RO reverse osmosis purification module for primary purification and secondary deep purification. The RO reverse osmosis purification module has a built-in reverse osmosis filter cartridge and is equipped with inlet, waste, and clean water outlets. It is connected to the quick-connect outlet 106 via a quick-connect method. The pressure of the variable frequency booster pump 112 built into the main unit module 1 drives the primary purified water to pass through the RO membrane to complete the deep purification.

[0034] The above scheme constructs a two-stage stratified purification system. The PPC composite filter element 103 can complete the first stage of water purification, effectively filtering large particulate impurities such as silt, suspended solids, colloids, and insect eggs, thus initially purifying the water quality. Through the external RO reverse osmosis purification module, the second stage of deep purification can be achieved, precisely filtering out small harmful substances such as heavy metals, bacteria, viruses, and scale, completely solving the problem of unstable water quality in complex outdoor water sources. The modular quick-connect design allows for free switching between single-stage and dual-stage purification modes according to water quality conditions, accommodating both ordinary cleaning water and safe drinking water needs, and is suitable for various complex outdoor water sources.

[0035] Specifically, the gas heating unit 113 includes a high-efficiency heat exchanger, an electronically controlled gas valve, and an igniter. Temperature sensors are installed at each of the quick-connect water outlets 106. The controller of the operation panel 101 is configured to execute a PID algorithm to adjust the opening of the gas valve.

[0036] Using the above solution, the dual-point temperature sensor can accurately collect inlet and outlet water temperature data in real time, realizing full-process water temperature monitoring. Relying on the PID intelligent algorithm, the opening of the electronic control gas valve is dynamically adjusted to accurately control the gas intake. Compared with the traditional fixed-fire heating method, the temperature regulation accuracy is higher and the temperature control is more stable. Combined with a high-efficiency heat exchanger, the gas heat utilization rate is greatly improved, effectively improving the problems of low heating efficiency and large water temperature fluctuations in low temperature and high altitude environments. It achieves energy-saving, efficient, and constant-temperature stable hot water output, avoiding the experience of sudden hot and cold water.

[0037] Specifically, it also includes an instant heating mode and a preheating mode. In the instant heating mode, the controller of the operation panel 101 detects the water flow signal and triggers ignition. It also dynamically adjusts the opening of the gas valve through a PID algorithm to maintain the outlet water temperature. In the preheating mode, the outlet rotary valve 111 switches to the circulation water inlet 107 to form a closed circulation water circuit of water tank-main unit-water tank. The variable frequency booster water pump 112 drives the water flow to circulate and heat. When the temperature reaches the set value, the controller closes the gas valve. The variable frequency booster water pump 112 continues to run for a set time and then stops.

[0038] The above solution offers dual heating modes to suit different outdoor water usage scenarios. The instant heating mode provides hot water as soon as it is turned on, igniting when water is supplied and stopping when water is cut off, eliminating the need for preheating. It is suitable for short-term, sporadic water needs for washing and handwashing, and is energy-saving and efficient. The preheating mode uses a closed-loop water circuit to circulate and heat the entire tank of water evenly, enabling a large-capacity constant-temperature hot water storage, which is suitable for scenarios with high water usage such as long-term showers and bulk kitchenware cleaning.

[0039] Working principle of the invention: During use, the positioning protrusion 114, positioning hole 403, side block 404, and locking groove of each module make the main unit module 1, water tank module 2, and water trough module 3 securely integrated on the trolley 4. Each module can be individually disassembled or freely combined according to usage needs, and is easy to disassemble and assemble. The MOLLE tactical mounting plate can be used to attach accessories. The folding legs 302 and the openable cover 303 of the water trough module 3 can realize independent washing and temporary storage functions.

[0040] Water source and waterway switching: Rotate to switch between two water intake modes. One is the built-in water tank water intake mode, which directly draws water stored in the water tank module 2. The other is the external water source water intake mode, which draws natural water sources such as streams and lakes through external pipelines. Rotating the outlet rotary valve 111 allows switching between two types of water circuits: one is the water supply circuit, where water is pressurized, purified, and heated by the main unit before being supplied to the outside through the quick-connect outlet 106, meeting the water needs for washing, showering, and equipment cleaning; the other is the preheating circulation circuit, where water flows into the circulation inlet 107 at the top, forming a closed loop of water tank-main unit-water tank, realizing the circulation and preheating of the entire tank of water. The entire water circuit relies on the variable frequency booster pump 112 to provide water delivery power, ensuring stable outlet water pressure.

[0041] Water purification: After entering the main unit, the water first flows through the PPC composite filter 103 in the filter chamber 102 to complete the first-stage purification, which intercepts large particulate impurities such as silt, suspended solids, colloids, and insect eggs in the water. If it is necessary to prepare drinking water, an RO reverse osmosis purification module is connected to the quick-connect outlet 106. The water pump pressure drives the water body to complete the second-stage deep purification, effectively filtering out heavy metals, bacteria, viruses, and ionic pollutants in the water. Users can flexibly choose the single-stage purification or two-stage deep purification mode according to the cleanliness of the water source and the purpose of water use.

[0042] Heating and temperature control: The device has two heating modes: instant heating and preheating; Instant heating mode: When water flows through the pipeline, the controller detects the water flow signal and immediately triggers the igniter to ignite; the temperature sensors at the inlet and outlet collect water temperature data in real time, and the controller runs a PID algorithm to dynamically adjust the opening of the electronic control gas valve to accurately control the gas supply. Together with the high-efficiency heat exchanger, it achieves rapid heat exchange and stabilizes the outlet water temperature within the set range. When water usage stops and the water pump stops, the heating system stops working synchronously. Preheating mode: After the water circuit is switched to a closed loop, the variable frequency booster water pump 112 drives the water in the tank to circulate continuously, and the gas heating unit 113 continuously heats the circulating water. When the sensor detects that the water temperature has reached the set value, the controller closes the electronic control gas valve to stop heating, and the water pump continues to run for a preset time before stopping, thus completing the constant temperature preheating of the entire tank of water.

[0043] The entire machine is powered by the energy storage battery in the battery compartment 109, which provides working power to each drive component. The operator sets the working mode, target water temperature and other parameters through the operation panel 101. The entire machine automatically completes the entire process of water intake, purification, heating and water delivery according to the set program.

7. The multifunctional portable water treatment and heating device as described in claim 6, characterized in that: It also includes an instant heating mode and a preheating mode. In the instant heating mode, the controller of the operation panel (101) detects the water flow signal and triggers ignition. It dynamically adjusts the opening of the gas valve through the PID algorithm to maintain the outlet water temperature. In the preheating mode, the outlet rotary valve (111) switches to the circulating water port (107) to form a closed circulating water circuit of water tank-main unit-water tank. The variable frequency booster water pump (112) drives the water flow to circulate and heat. When the temperature reaches the set value, the controller closes the gas valve.
