Description

Technical Field

[0001] This utility model belongs to the field of household water supply technology, and in particular relates to an outdoor water purifier structure. Background Technology

[0002] People engaged in outdoor activities typically carry high-quality portable water purifiers to effectively remove organic sediments, rust, suspended solids, dust, various pathogens, bacteria and microorganisms, and odors from water. Furthermore, emergency drinking water safety devices are urgently needed in the event of natural disasters such as floods, earthquakes, landslides, and mudslides, as well as sudden water pollution incidents.

[0003] Chinese utility model patent document CN216038911U discloses a micro water purifier that can be operated with one hand, consisting of a micro filter device and a raw water pressurization device. The micro filter device consists of a filter cylinder, a filter inlet, a filter outlet, and a filter media assembly located inside the filter cylinder. The filter media assembly is composed of a composite carbon fiber filter element, filter plates, and an ultrafiltration membrane. The raw water pressurization device consists of a pressurization device inlet, a pressurization device body, and a pressurization device outlet. The micro filter device and the raw water pressurization device are two separable parts, which are detachably and fixedly connected to the pressurization device body via the filter cylinder. In this embodiment, a connecting sleeve is provided between the filter cylinder and the pressurization device body, and the filter cylinder and the connecting sleeve are detachably threaded and fixedly connected. The connecting sleeve has a protrusion that is fixedly connected to the shell of the pressurization device body by a snap-fit. In this way, the micro filter device can be easily disassembled to replace the filter media assembly. The pressurization device outlet is connected to the filter inlet, and the raw water from the raw water pressurization device enters the micro filter device through the filter inlet. The pressurizing device mainly includes a piston assembly, an inlet check valve located at the front end of the piston assembly, and an outlet check valve located at the rear end of the piston assembly. In this embodiment, the inlet and outlet check valves are diaphragm-type check valves, which can significantly reduce the size of the entire micro-filter device. Of course, based on the common knowledge of those skilled in the art, other types of check valves, such as duckbill check valves or ball check valves, can also be used. The piston assembly includes a piston cylinder, a piston, a sealing ring located between the piston cylinder and the piston, and a piston cylinder end cap. The piston cylinder has a piston inlet and a piston outlet. A return spring is provided between the piston and the piston cylinder. The piston has a piston push rod extending out of the piston cylinder end cap. A cylindrical rod handle is fixed to the end of the piston push rod. This cylindrical rod handle is detachably and movably connected to the piston push rod for easy carrying. Of course, the cylindrical rod handle can also be other shapes of handles, for the purpose of easy carrying and use. The inlet check valve is connected to the piston inlet, and the piston outlet is connected to the outlet check valve. By pressing the cylindrical handle and the action of the return spring, the main body of the pressurizing device can draw in the raw water from the inlet of the pressurizing device and pump it out from the outlet of the pressurizing device, and then it enters the micro filter device.

[0004] The aforementioned patent documents disclose that water purifiers require filter cleaning after use. There are generally two methods for cleaning the filter: one is to disassemble the filter for cleaning, and the other is to perform reverse cleaning. Reverse cleaning involves injecting clean water from the water purifier's outlet in the opposite direction to clean the filter.

[0005] Currently, reverse cleaning of the filter cartridge involves using a piston pump (syringe) to draw water and then repeatedly injecting cleaning water into the outlet. This operation is relatively cumbersome and requires an additional cleaning pump. Utility Model Content

[0006] The purpose of this utility model is to provide an outdoor water purifier structure that uses the water pump of the water purifier itself to achieve reverse cleaning of the filter element, without the need for a separate cleaning pump.

[0007] To achieve the above objectives, this utility model provides an outdoor water purifier structure, comprising: a shell, a filter element, a water pump, a water intake pipe, and a cleaning pipe; the filter element is disposed inside the shell, and the shell includes a first end and a second end, the first end being provided with a water outlet and the second end being provided with a connector; one end of the water pump is provided with a connector, and the other end is provided with a pipe joint; The connecting end is connected to the second end, and the pipe joint is connected to the water intake pipe, forming a water purification structure; The cleaning pipe connects the pipe joint and the connector to form a filter element cleaning structure.

[0008] Furthermore, the water pump is a manual pump.

[0009] Furthermore, one end of the water intake pipe is equipped with a water inlet screen.

[0010] Furthermore, the water intake pipe is also fitted with a float, which can slide and adjust on the water intake pipe.

[0011] Furthermore, the water intake pipe and the cleaning pipe are the same flexible hose.

[0012] The above-mentioned one or more technical solutions in the outdoor water purifier structure provided by this utility model embodiment have at least the following technical effects: 1. When purifying water, the water pump is connected to the second end of the outer casing, and the pipe connector is connected to the water intake pipe. One end of the water intake pipe is inserted into the water source, and the water pump draws water into the outer casing, filters it through the filter element, and outputs it from the outlet, thus obtaining clean water that can be drunk directly.

[0013] 2. When backwashing the filter element is required, separate the water pump from the housing, detach the water inlet pipe from the pipe connector, and connect the cleaning pipe to the pipe connector and connector. Immerse the entire housing in clean water. By operating the water pump, the cleaning water enters from the outlet to backwash the filter element, washing away dirt, sediment, etc., from the outer wall of the filter element, and then discharges it from the water pump connection until the discharged water is clean.

[0014] 3. This outdoor water purifier uses its own water pump to achieve reverse cleaning of the filter cartridge, eliminating the need for an additional cleaning pump, and the cleaning operation is simple. Furthermore, the water pump is always in contact with unpurified water, so there is no issue of the pump contaminating the pump or the filter cartridge. Attached Figure Description

[0024] For one embodiment of the outdoor water purifier of this utility model, please refer to... Figures 1 to 4 The outdoor water purifier of this embodiment can purify water from outdoor sources for direct drinking by users, and it is also easy to carry.

[0025] Specifically, the outdoor water purifier structure of this embodiment includes a housing 100, a filter element 200, a water pump 300, a water intake pipe 400, and a cleaning pipe 500. The filter element 200 is disposed inside the housing 100, which includes a first end 101 and a second end 102. The first end 101 is provided with a water outlet 110, and the second end 102 is provided with a connector 120. One end of the water pump 300 is provided with a connector 310, and the other end is provided with a pipe connector 320. Preferably, the water pump 300 is a manual pump.

[0026] When purifying and using outdoor water sources, the connecting end 310 is connected to the connector 120 of the second end 102. The pipe connector 320 is connected to the water intake pipe 400, thus forming a water purification structure.

[0027] The cleaning pipe connects the pipe fitting and the connector to form a filter cleaning structure. One end of the water intake pipe 400 is inserted into the water source, and the water pump 300 is operated. The water pump 300 draws water into the outer casing 100, and after being filtered by the filter element 200, it is output from the water outlet 110, thus obtaining clean water that can be drunk directly.

[0028] When backwashing of filter element 200 is required, the water purifier can first purify a certain amount of clean water. Then, the water pump 300 is disassembled from the outer casing 100, the water inlet pipe 400 is detached from the pipe connector 320, and the cleaning pipe 500 is connected to the pipe connector 320 and the connector 120. The entire outer casing 100 is then placed into the purified water. By operating the water pump, cleaning water enters from the outlet 110 to backwash the filter element 200, washing away dirt, sediment, and other contaminants from the outer wall of the filter element 200. The water is then discharged from the water pump connection 310 until the discharged water is clean. This outdoor water purifier utilizes its own water pump 300 to achieve backwashing of the filter element 200, eliminating the need for an additional cleaning pump, and the operation is simple. Furthermore, the water pump 300 is always in contact with unpurified water, eliminating the risk of the pump contaminating the purified water source or the interior of the filter element 200.

[0029] Furthermore, one end of the water intake pipe 400 is provided with a water inlet screen 410. The water screen 410 facilitates the insertion of the water intake pipe 400 into the water and prevents large debris from entering the water intake pipe 400.

[0030] Furthermore, the water intake pipe 400 is also fitted with a float 420, which can slide and adjust on the water intake pipe 400. In this embodiment, the float 420 can be used to suspend the end of the water intake pipe 400 in the water, preventing it from extending to the bottom and sucking in too much mud and sand.

[0031] Another embodiment of the outdoor water purifier differs from the above embodiment only in that the water intake pipe and the cleaning pipe are the same flexible hose. This eliminates the need for one of the hoses, making it more convenient to carry.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
