Description

Technical Field

[0001] This invention relates to a water purifier, belonging to the field of water purifier technology. Background Technology

[0002] Water purifiers are primarily devices used in homes. Current technology focuses heavily on kitchen water purifiers, such as the commonly used cabinet-mounted models that filter tap water to provide drinking water. However, water purification devices are not limited to ordinary households; their applications are diverse. For example, they can be used outdoors, where the water source is from rivers or lakes. In emergencies like earthquakes or floods, water pollution can be severe. Existing technologies offer solutions to some of these problems.

[0003] For example, how to solve the drinking water problem in the wild during a self-driving tour? Existing technologies offer some solutions using portable water purifiers. For instance, CN202320719210.0 discloses a portable water purification device, including a water purification cup body. A limiting shell is fixedly installed on the right inner wall of the water purification cup body. Water purification components for purifying water are provided on the surface of the water purification cup body and the surface of the limiting shell. Specifically, a limiting shell 2 is fixedly installed on the right inner wall of the water purification cup body 1. Water purification components 3 for purifying water are provided on the surface of the water purification cup body 1 and the surface of the limiting shell 2. A top cover assembly 4 is provided on the top of the water purification cup body 1, and a bottom cover 5 is threaded into the bottom of the water purification cup body 1. A pressurizing mechanism 6 for pressurizing the inside of the water purification cup body 1 is provided on the left side wall of the water purification cup body 1. The water purification components 3 are inserted into the inside of the water purification cup body 1 and the surface of the limiting shell 2, and water is purified through the top cover assembly 4. Water is added to the interior of the body 1. The top cover assembly 4 includes a cover 401 threadedly inserted into the top of the water purification cup body 1. A water inlet 402 and a water outlet 403 are located on the top of the cover 401. A water outlet pipe 404 is inserted into the top of the limiting shell 2, with the bottom end of the water outlet pipe 404 located inside the limiting shell 2. Water is easily added to the interior of the water purification cup body 1 through the water inlet 402, and purified water is easily drawn in through the water outlet 403 and the water outlet pipe 404. This device is portable but not aesthetically pleasing, has a small water capacity, and its filtration relies on a single inserted water purification component, limiting its filtration capacity. The purified water produced cannot meet the requirements for direct drinking water.

[0004] For use in emergencies such as earthquakes or floods, existing technologies, such as the portable water purifier disclosed in JP2004234054, are equipped with a carrying case. This carrying case consists of a waterproof shell that can be used as a water container and a lid that can be opened and closed. The lid houses a filter that purifies dirty water to produce drinking water, and also includes a pump unit that draws in the dirty water contained in the main body and sends it to the filter. However, this carrying case requires opening the pivotally connected lid for use. Compared to the water purifier itself, it is too large and bulky to carry. Although its purification capacity is far greater than the former, its excessive weight prevents it from meeting the needs of various application scenarios.

[0005] There is a lack of a water purifier that can be convenient to carry and use for various different application scenarios, while also meeting drinking water requirements. Summary of the Invention

[0006] In view of the above-mentioned problems existing in the prior art, the main objective of the present invention is to provide a water purifier that can be used in a variety of different application scenarios, has a more reasonable structure, and is convenient to carry and use, while also meeting the requirements for drinking water.

[0007] The purpose of this invention is to solve the above-mentioned problems in the prior art and provide a water purifier, including a main body and a cover. An L-shaped notch is provided on the upper side of the main body, which is formed by connecting two adjacent body wall panels. The cover matches the L-shaped notch and is installed at the L-shaped notch of the main body to form an integral shape. The main chamber is equipped with a water pump and an RO membrane. When storing, the primary filter component is placed inside the lid. When using, the primary filter component is placed at the water source to draw water and perform primary filtration on the water. After primary filtration, the particle size of the particulate matter in the water is at the micron level. The primary filtration component is connected to a water pump via an inlet pipe, and the water is directly output to the purified water pipe or to the RO membrane. After filtration by the RO membrane, the purified water is output to the direct drinking water pipe.

[0008] Furthermore, in applications such as outdoor freshwater source environments, post-earthquake flood water source environments, or underground well environments, the water purifier uses a pre-filter component placed in the water source, with a water pump in the main tank pressurizing and pumping the water. After pre-purification by the pre-filter component, purified water is produced, or after further filtration by an RO membrane, drinking water is output.

[0009] Furthermore, the overall shape is a cuboid with chamfered sides, a drum shape, or a cylinder shape.

[0010] Furthermore, the pre-filtration assembly includes a housing with an inlet and an outlet, or is provided with an outlet. Water enters through a filter screen on the housing. Pre-filtration material is provided inside the housing, which is one or any combination of PP cotton, ultrafiltration, or activated carbon.

[0011] Furthermore, the main housing is also equipped with pipelines connected to the water pump and RO membrane, as well as one or more combinations of solenoid valves, check valves, wastewater ratio valves, high-pressure switches, pressure gauges, and heaters installed on the pipelines.

[0012] Furthermore, the water pump is either an electric water pump or a manual water pump, and the main housing may or may not have a power module. When a power module is provided, its output is connected to the motor of the electric water pump.

[0013] Furthermore, the main housing has a bottom plate, a top plate, four wall panels, a side panel, and a cover plate. The bottom plate, top plate, four wall panels, and side panel are integrally formed to enclose the housing cavity. The cover plate is installed on the opening surface of the housing cavity. A drinking water outlet and / or a purified water outlet are provided on the wall panel of the L-shaped notch. A water inlet and / or a concentrated water drain outlet are provided on the wall panel or on the lower side of the main housing. Water pipe connectors are installed on the drinking water outlet, purified water outlet, water inlet, and concentrated water drain outlet.

[0014] Furthermore, the main housing has a length of 35cm or less, a width of 25cm or less, and a thickness of 13cm or less. The housing wall panel of the L-shaped notch facade is also provided with a control switch hole, and the power interface hole may or may not be provided on the housing wall panel of the L-shaped notch facade.

[0015] Furthermore, the box cover is installed using one or any combination of plug-in, snap-in, magnetic connection, and screw connection; the box cover is connected to the main box using one or any combination of plug-in, snap-in, and magnetic connection.

[0016] Furthermore, a dovetail block is provided on the box cover, and a dovetail groove is provided on the box wall panel of the L-shaped notch of the main box body, so that the box cover is connected to the main box body by insertion; a card block is provided on the side of the box cover corresponding to the L-shaped notch, and a card hole is provided on the box wall panel of the L-shaped notch, so that the card block can be inserted into the card hole for engagement.

[0017] The advantages of this invention over the prior art are as follows: 1. The main body with an L-shaped notch provides a space for placing a cup, making it both portable and convenient to use; Second, the cover that connects with the L-shaped notch makes the machine look more aesthetically pleasing. At the same time, the cover blocks the water outlet, making it more hygienic. The space inside the cover is used to store pipes and other components, making it more convenient to use. 3. The main body has a compact structure, cleverly utilizing the body to install the water pump, RO membrane and accessories. The pre-filter is easy to replace, and the small size can achieve the supply of direct drinking water.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0020] Example 1 like Figure 1 The water purifier shown includes a main body 1 and a cover 2. An L-shaped notch formed by two adjacent body panels is provided on the upper side of the main body 1. The cover 2 matches the L-shaped notch and is installed at the L-shaped notch of the main body to form an integral shape. A water pump and an RO membrane are installed inside the main body. When storing, the pre-filter component is placed inside the cover. When using, the pre-filter component is placed at the water source to draw water and perform pre-filtration on the water source. The pre-filter component is connected to the water pump through the inlet pipe, and the water is directly output to the purified water pipe or output to the RO membrane. After filtration by the RO membrane, it is output to the direct drinking water pipe.

[0021] Because the pre-filter is placed outside the main unit, it acts as a pre-filtration stage and can be easily replaced. The subsequent RO membrane can then function at its maximum capacity, producing tens of tons of drinking water to meet the demand for safe drinking water. This design makes the water purifier smaller and more portable. Whether carried in a backpack or used as a car unit, it takes up minimal space and is lightweight, meeting the need for portability. The pre-filter is connected via a water pipe, allowing for direct immersion in lakes or rivers to collect water, solving the problem of convenient water access. The pre-filter is also concealed within the lid, making it more aesthetically pleasing and facilitating overall storage and transport.

[0022] The water purifier in this embodiment can obviously meet the needs of indoor use, but it is more suitable for outdoor freshwater source environments (vehicle-mounted or portable) during outdoor activities, or water source environments after earthquakes and floods. The pre-filter is placed in the water source, and the water is pumped out by the water pump in the main tank. After passing through the pre-filter, purified water is produced, or after being filtered by the RO membrane, it is output as drinking water.

[0023] Example 2 like Figure 2 , 3 A water purifier as shown in Figure 4 includes a main body 1 and a cover 2. An L-shaped notch is provided on the upper side of the main body 1, formed by two adjacent body wall panels 10. The body panels form a cavity for installing water purifier components. The cover 11 is installed on the opening surface of the cavity. A drinking water outlet 3 and a purified water outlet 4 are provided on the body wall panel on the vertical side of the L-shaped notch. A drinking water outlet connector is installed on the drinking water outlet 3, and a purified water outlet connector is installed on the purified water outlet 4. A water inlet 5 and / or a concentrated water drain 6 are provided on the body wall panel. A water inlet connector is installed on the water inlet, and a concentrated water drain connector is installed on the concentrated water drain 6. The cover 2 is installed at the L-shaped notch of the main body 1, matching the L-shaped notch, forming a cubical overall shape.

[0024] A control switch hole 7 is provided on the wall panel of the L-shaped notch facade. The control switch is installed at the control switch hole 7. A power interface hole 8 is provided on the wall panel of the L-shaped notch facade. The power interface is installed at the power interface hole 8. The power interface is used to connect to an external power source. This device does not require a control circuit. When the control switch is turned on (in this embodiment, the control switch is a two-position switch, used to control the output of drinking water or purified water respectively), the power supply powers the miniature electric water pump and solenoid valve, and water can be dispensed. If a 2800mA battery is used, the working time is 3-4 hours, providing nearly 50 liters of drinking water.

[0025] The L-shaped notch design creates a cabinet with a long chamber and a short chamber. The RO membrane filter is installed in the long chamber, and the water pump is installed in the short chamber, naturally meeting the design requirements for installation space. The main cabinet with the L-shaped notch provides space for placing a cup, making it both portable and convenient to use. The lid, which connects to the L-shaped notch, enhances the overall aesthetics of the machine. The lid also conceals the water outlet for better hygiene, and the space inside the lid is used to store pipes and other components for added convenience. The main cabinet has a compact structure, cleverly integrating the water pump and RO membrane to provide direct drinking water. It can also be powered externally, making it suitable for various application scenarios.

[0026] In this embodiment, the main housing 1 has a bottom plate 12, a top plate 13, four wall panels 10, a side panel 14, and a cover plate 11. The bottom plate 12, top plate 13, four wall panels 10, and side panel 14 are integrally formed to enclose the housing cavity. A recessed groove is provided on the inner wall of the housing cavity, and the cover plate is installed on the recessed groove. An insertion groove is provided on the recessed groove, and an insertion rod is provided on the cover plate for corresponding insertion connection. Alternatively, screw holes can be provided for screwing with countersunk screws.

[0027] A dovetail block 21 is provided on the lid 2, and a dovetail groove is provided on the box wall panel of the L-shaped notch of the main box body. The lid is connected to the main box body by insertion. At the same time, a card block 22 is provided on the side of the L-shaped notch of the lid 2, and a card hole is provided on the box wall panel of the L-shaped notch. The card block is inserted into the card hole and engaged.

[0028] The box structure in this embodiment is easy to carry, does not take up too much space in a vehicle, and is easy to place. When used in a vehicle, it can be powered directly by the vehicle's power supply; it can also be placed in a personal backpack for use in the wild. It is lightweight and does not pose a burden, solving the problem of safe drinking water in the wild. When used in the wild, it can be powered by a portable power source or a hand pump; it can also be used as a backup water purification device for families, communities, etc., in emergency situations such as earthquakes or floods. It is easy to store and occupies little space.

[0029] Example 3 In a water purifier different from Embodiment 2, the power interface hole 8 is located on the side panel 14 of the housing. A rechargeable battery is installed in the space of the housing, and a charging power connector is installed on the power interface hole for connecting the rechargeable battery to charge it.

[0030] The water inlet 5 and the concentrated water drain 6 are located on the lower side panel 10 of the main body, or they can be located on the lower side panel 14 of the main body. The water inlet 5 and the concentrated water drain 6 can be located together on the same panel or separately on different panels. The design is mainly for ease of use and aesthetic appeal.

[0031] Example 4 A water purifier different from Embodiment 2 includes a main body and a lid, with an overall shape of a waist drum. The main body still includes a bottom plate 12, a top plate 13, four wall panels 10, a side panel 14, and a lid 11. The bottom plate 12, top plate 13, four wall panels 10, and side panel 14 are integrally formed to enclose the cavity. However, the outer walls of the two wall panels located on both sides of the side panel are curved.

[0032] Of course, we can also make the outer walls of the box side panel 14, the two box wall panels 10 located on both sides of the box side panel, and the box cover 11 into an arc shape, forming a full waist drum shape. This design does not change the overall structural features of Embodiment 1 and the functions generated by these structural features.

[0033] Application Example 1 For outdoor use, such as camping by a lake, if you are driving, you can use a car-mounted unit to carry the water purifier of this invention in your vehicle. When camping, collect water, and pump the water from the outlet into the water purifier through the pre-filter component (a porous filter screen on the housing). After filtration by the RO membrane, the water becomes drinkable. The concentrated water discharged can be used to wash utensils. In this case, an electric water pump can be used, and the power source can be either a battery installed in the water purifier or the water purifier can be powered by the vehicle's power supply instead of a battery. In the case of being in a vehicle, a heater can be used to meet the heating needs of the water source.

[0034] For outdoor use, if the hike lasts for several days or longer, a manual pump is recommended. However, the water purifier of this invention is small in size, with the main body being less than or equal to 35cm in length, 25cm in width, and 13cm in thickness. This makes it convenient for individuals to carry in their backpacks, and it is also lightweight, thus solving the problem of personal drinking water in the wild.

[0035] Water can be obtained from streams, creeks, or ditches.

[0036] Application Example 2 In disaster relief and rescue operations, such as addressing drinking water issues for people in mountainous areas, one water purifier of this invention (using a manual pump) can produce tens of tons of drinking water, enough to meet the needs of many people for several days. During floods, the high risk of disease outbreaks is primarily due to unhealthy drinking water; this water purifier is sufficient to meet the drinking water needs of a family for dozens of days during a flood. Of course, the same applies to drinking water after an earthquake.

[0037] Application Example 3 Used underground in mines, this manual pump meets the drinking water needs of multiple people underground. Especially in the event of an accident, it can solve the drinking water problem for trapped personnel, prolong their lives, and buy time for rescue.

[0038] The above embodiments are merely explanations and illustrations of the technical solutions of the present invention and should not be used to limit the scope of protection of the technical solutions of the present invention. All simple modifications based on this solution are within the scope of protection of the present invention.
