The water purification device 10 can be applied to various places with water purification needs.

[0040] In some embodiments, referring to FIG. 3 , the water purification equipment 10 includes a filtration module for treating water, the filtration module includes an ultrafiltration module 20, the ultrafiltration module 20 includes an ultrafiltration filter element 21, and the ultrafiltration membrane in the ultrafiltration filter element 21 can efficiently filter the raw water (water that has just entered the water purification equipment 10) to obtain ultrafiltered water. After being treated by the ultrafiltration filter element 21, most of the mud, rust, suspended matter and colloids in the raw water can be filtered out, thereby ensuring the safety of the water quality.

[0041] In some embodiments, referring to FIG. 3 , the ultrafiltration module 20 may further include a pretreatment filter element 22. The pretreatment filter element 22 may be disposed upstream of the ultrafiltration filter element 21 along the flow direction of the raw water. The pretreatment filter element 22 may pretreatment the raw water, including but not limited to removing coarse particle impurities, silt impurities, organic pollutants, etc. in the raw water. The water filtered by the pretreatment filter element 22 flows into the ultrafiltration filter element 21 for filtration, which can reduce the filtration pressure of the ultrafiltration filter element 21 and is conducive to increasing the service life of the ultrafiltration filter element 21.

[0042] The present application does not limit the specific selection of the pretreatment filter element 22. In some embodiments, the pretreatment filter element 22 may be a PP cotton filter element (Polypropylene, polypropylene spray-melt filter element), which is a high-density fiber cotton filter element that can filter out larger particles of impurities; or, the pretreatment filter element 22 may be a GAC ​​filter element (Granular Activated Carbon Filter, granular activated carbon filter element), which can effectively remove small molecular organic matter and residual chlorine in the water, and can absorb discoloration and odor in the water. When the pretreatment filter element 22 includes both a PP cotton filter element and a GAC ​​filter element, the PP cotton filter element can be located upstream of the GAC filter element along the flow direction of the water. In one embodiment of the present application, the pretreatment filter element 22 may be a composite filter element, which has the functions of both a PP cotton filter element and a GAC ​​filter element, and can achieve pretreatment of raw water.

[0043] In some embodiments, referring to Figures 7 and 8, the filtration module also includes a reverse osmosis module 30, and the reverse osmosis module 30 includes a reverse osmosis filter element 31. Along the direction of water flow, the reverse osmosis filter element 31 can be located downstream of the ultrafiltration filter element 21. The ultrafiltration water treated by the ultrafiltration filter element 21 can flow into the reverse osmosis filter element 31 for reverse osmosis treatment to obtain pure water.

[0044] In some embodiments, referring to FIG. 7 and FIG. 8 , the reverse osmosis module 30 may further include a driving member 32 connected to the reverse osmosis filter element 31 , and the driving member 32 is used to increase the pressure of water flowing into the reverse osmosis filter element 31 .

[0045] The present application does not limit the specific selection of the driving component 32. In some embodiments, the driving component 32 may be a motor, a booster pump, etc.

[0046] The present application does not specifically limit the number of filter elements and drive elements 32 of the water purification device 10. In some embodiments, the number of ultrafiltration filter elements 21 and pretreatment filter elements 22 can be one each, and the pretreatment filter element 22 can be a composite filter element. After being treated with the composite filter element and the ultrafiltration filter element 21, ultrafiltration water can be obtained; the number of reverse osmosis filter elements 31 can be multiple, and multiple reverse osmosis filter elements 31 can speed up the efficiency of reverse osmosis treatment of the water purification device 10. The number of drive elements 32 can be the same as the number of reverse osmosis filter elements 31 and be arranged one by one to achieve pressurization of water flowing into the corresponding reverse osmosis filter element 31. In an embodiment of the present application, referring to Figures 7 and 8, the number of reverse osmosis filter elements 31 can be two, and pure water can be obtained after being treated with the reverse osmosis filter element 31. The number of drive elements 32 can also be two, and two drive elements 32 are arranged correspondingly to the two reverse osmosis filter elements 31.

[0047] In some embodiments, referring to FIG. 1 and FIG. 13 , the water purification device 10 further includes a water storage module 310 , and the water storage module 310 includes a pressure barrel 311 connected to the ultrafiltration module 20 and / or the reverse osmosis module 30 , and the pressure barrel 311 is used for storing water.

[0048] In some embodiments, referring to FIG. 1 , the ultrafiltration module 20, the reverse osmosis module 30 and the water storage module 310 of the water purification device 10 can be independently three devices, which allows users to make different combinations according to actual needs, and the assembly flexibility is high. For example, the user can choose only one of the devices integrated with the ultrafiltration module 20, the reverse osmosis module 30 and the water storage module 310, or integrate any two of the above three devices, or integrate the above three devices at the same time. When the actual needs of the user change, the user can also make changes based on the original device combination, such as by adding a hose or reducing a hose to achieve a change in combination. Among them, the water outlet of the ultrafiltration module 20 is detachably connected to the water inlet of the reverse osmosis module 30, and the water inlet of the water storage module 310 is detachably connected to the water outlets of the ultrafiltration module 20 and the reverse osmosis module 30.

[0049] In the above embodiment, the pressure barrel 311 can be connected only to the ultrafiltration module 20 or the reverse osmosis module 30, that is, the pressure barrel 311 can be connected to the water outlet end of the ultrafiltration filter element 21 or the water outlet end of the reverse osmosis filter element 31. When the pressure barrel 311 is connected to the water outlet end of the ultrafiltration filter element 21, ultrafiltration water is stored in the pressure barrel 311. When the pressure barrel 311 is connected to the water outlet end of the reverse osmosis filter element 31, pure water is stored in the pressure barrel 311. The ultrafiltration membrane of the ultrafiltration filter element 21 can intercept harmful substances such as mud, colloids, organic matter, etc. in the water. The reverse osmosis membrane of the reverse osmosis filter element 31 has a high filtration accuracy, and its filtration accuracy is usually below 0.0001 microns, which can filter out smaller molecules in the water. Therefore, for areas with better water quality, the water purification equipment 10 may include a water storage module 310 and one of the ultrafiltration module 20 and the reverse osmosis module 30. Preferably, based on considerations of usage costs and beneficial minerals in water, the water purification equipment 10 may include a water storage module 310 and an ultrafiltration module 20; for areas with poor water quality, the water purification equipment 10 may simultaneously include an ultrafiltration module 20, a reverse osmosis module 30 and a water storage module 310 to achieve multiple treatments of raw water, which is conducive to achieving drinking water safety.

[0050] In some embodiments, when the water purification equipment 10 includes an ultrafiltration module 20, a reverse osmosis module 30 and a water storage module 310 at the same time, the ultrafiltered water obtained by filtering the ultrafiltration module 20 and the pure water obtained by filtering the reverse osmosis module 30 can be mixed by designing the water channel structure to obtain drinking water with better drinking taste.

Since the ultrafiltration module 20 includes a pre-treatment filter element 22 and an ultrafiltration filter element 21, and its own weight is relatively large, therefore, out of consideration for the self-weight of the ultrafiltration module 20, the pre-treatment filter element 22 and the ultrafiltration filter element 21 may be connected to the side of the load-bearing plate 1 close to the ground.

[0052] In some embodiments, the first direction Z, the second direction X and the third direction Y can be perpendicular to each other, wherein the first direction Z can be the height direction of the water purification equipment 10, the second direction X can be the length direction of the water purification equipment 10, the third direction Y can be the width direction of the water purification equipment 10, the first plane can be a horizontal plane, and the load-bearing plate 1 can be parallel to the first plane, thereby improving the structural strength of the first shell 100 to a certain extent.

[0053] In some embodiments, the filter element of the ultrafiltration module 20 can be detachably connected to the load-bearing plate 1, that is, the pretreatment filter element 22 and the ultrafiltration filter element 21 can both be detachably connected to the load-bearing plate 1, so as to facilitate the maintenance or replacement of the pretreatment filter element 22 and the ultrafiltration filter element 21. Referring to FIG3, the pretreatment filter element 22 and the ultrafiltration filter element 21 can be arranged in parallel and detachably connected to the same side of the load-bearing plate 1, respectively.

In some embodiments, the detachable manner may be a fastener, that is, the relevant components may be provided with a first connection hole, and the fastener may be inserted into the first connection hole to achieve the connection of the relevant components, wherein the fastener includes but is not limited to bolts and nuts. In other embodiments, the detachable manner may also be a snap connection.

[0055] In some embodiments, referring to FIG. 3 , the first shell 100 may further include a plurality of reinforcing ribs 119 , which may extend along the second direction X and / or the third direction Y. The reinforcing ribs 119 may be connected to the side panels 116 , the load-bearing plates 1 , etc., thereby improving the structural strength of the first shell 100 and, to a certain extent, preventing the first shell 100 from being concave after a collision.

[0056] In the above embodiment, the load-bearing plate 1 may be provided with a plurality of pipe holes for pipes to pass through. The present application does not specifically limit the number of pipe holes, and the number may be modified accordingly according to the specific situation of pipe layout.

[0057] In some embodiments, the load-bearing plate 1 may be provided with a plurality of mounting holes, which may be used to mount various valves and / or pipes of the water purification device 10, for example, the mounting holes may be used to mount water inlet valves, waste water valves, etc. Among them, the mounting holes may also be connected with mounting plates, which are used to mount various valves and / or pipes, and the mounting plates may provide mounting positions for the installation of valves and / or pipes, and may support valves and / or pipes.

[0058] In some embodiments, a pressure relief valve may be provided on the pretreatment filter element 22 and the ultrafiltration filter element 21 respectively, and a second through hole may be opened on the load-bearing plate 1 for the pressure relief valve to pass through. When the staff disassembles the pretreatment filter element 22 and the ultrafiltration filter element 21, they can first operate the pressure relief valve to relieve the pressure, thereby facilitating the disassembly of the pretreatment filter element 22 and the ultrafiltration filter element 21.

[0059] In some embodiments, referring to FIG. 1 to FIG. 3 , the bottom of the first housing 100 may be provided with a first roller 121 for rolling contact with the ground, so that the first housing 100 can move relative to the ground, facilitating the user to transfer the device integrated with the ultrafiltration module 20 .

[0060] The present application does not specifically limit the number of the first rollers 121 . In some embodiments, referring to FIGS. 1 to 3 , the number of the first rollers 121 may be four, and the four first rollers 121 may be respectively disposed near the four vertex corners of the bottom of the first shell 100 .

[0061] In some embodiments, referring to Figures 3 and 6, the first shell 100 of the water purification equipment 10 may include a bottom plate and a base 113 connected to each other, the base 113 and the first roller 121 are respectively arranged on both sides of the bottom plate, and the base 113 is provided with a first through hole 125, a second through hole 126 and a third through hole 127. The first through hole 125 is used for the water inlet joint to pass through, the second through hole 126 is used for the water outlet joint to pass through, and the third through hole 127 is used for the waste water joint to pass through. The base 113 can provide installation positions for the water inlet joint, the water outlet joint and the waste water joint at the same time.

[0062] In some embodiments, referring to FIG. 6 , the base 113 is recessed into the interior of the first shell 100 to form a receiving cavity 128, and the receiving cavity 128 is connected to the first through hole 125, the second through hole 126 and the third through hole 127. The receiving cavity 128 can accommodate the water inlet joint, the water outlet joint and the waste water joint to a certain extent, thereby avoiding the water inlet joint, the water outlet joint and the waste water joint from being exposed, and to a certain extent avoiding the water inlet joint, the water outlet joint and the waste water joint from colliding with the outside world, which is beneficial to protecting the water inlet joint, the water outlet joint and the waste water joint.

[0063] In some embodiments, referring to Figures 1 to 3, the first shell 100 of the water purification equipment 10 may also include a top plate 115 and two side plates 116, the top plate 115 is arranged opposite to the bottom plate, the two side plates 116 are both extended along the first direction Z, the two side plates 116 are spaced apart in the second direction X and are located between the top plate 115 and the bottom plate, the two ends of the two side plates 116 in the first direction Z are respectively connected to the top plate 115 and the bottom plate, and the base 113 is extended along the second direction X and connected to the two side plates 116.

[0064] In some embodiments, referring to Figures 1 to 3, the first shell 100 of the water purification equipment 10 may also include a front door 117 and a rear door (not shown) spaced apart in the third direction Y, one side of the front door 117 and the rear door are respectively rotatably connected to the side plate 116, and the front door 117 and the rear door both have a closed state. When the front door 117 is in the closed state, the two ends of the front door 117 in the first direction Z are respectively abutted against the top plate 115 and the bottom plate, and when the rear door is in the closed state, the two ends of the rear door in the first direction Z are respectively abutted against the top plate 115 and the base 113.

[0065] In the above embodiment, the front door 117 and the rear door each have an open state, which means that the front door 117 and the rear door rotate relative to the side plate 116 to be away from the load-bearing plate 1, so that it is convenient for the user to replace and repair the filter element in the first housing 100. The multiple valves and pipes in the water channel structure can be arranged as close to the rear door as possible, so that the internal structure of the water purification device 10 can be more beautiful after the front door 117 is opened, and it is also convenient for the user to replace the filter element located at the front side.

[0066] The present application does not limit the specific shapes of the bottom plate, side plate 116, top plate 115, front door 117 and rear door, and their shapes can be improved accordingly according to the needs of the actual application scenario. In some embodiments, the bottom plate, side plate 116, top plate 115, front door 117 and rear door can all be formed as flat plates, so that the first shell 100 as a whole can be formed into a prism shape, such as a rectangular parallelepiped or a cube shape.
