Description

Technical Field

[0001] The present invention relates to the technical field of water purification equipment, and in particular to an automatic water purification equipment and a water purification method. Background Art

[0002] A water purifier, also known as a water purifier or water purifier, is a water treatment device that deeply filters and purifies water according to specific usage requirements. Over time, the filter element will accumulate pollutants, bacteria, impurities, and scale, all of which will affect the filter's water purification effectiveness and device performance. Therefore, the filter element needs to be descaled and cleaned regularly.

[0003] A Chinese patent discloses an automatic descaling water purifier (authorization announcement number CN214680401U). When the drive motor is turned on, the rotation of the rotating rod will drive the rotating bevel gear to rotate stably, causing the meshing bevel gear to rotate under its meshing thrust, driving the upper end threaded rod to rotate. The threaded thrust cooperates with the setting of the fixed rod to enable the lifting ring to slide up and down, allowing the first and second descaling brushes to clean the scale in the purification cylinder. The purification cylinder is rotated, the threaded inner ring and the threaded outer ring are disengaged, and the purification cylinder can be removed.

[0004] Since the above-mentioned device places the threaded rod and the fixed rod directly in the water body containing scale, the scale can easily be retained on the surface of the threaded rod and the fixed rod as it flows with the water body, which will increase the resistance of the threaded rod to drive the lifting ring to rise and fall. In severe cases, it may even cause the lifting ring to get stuck and be unable to rise and fall normally, affecting the normal use of the cleaning structure. Summary of the Invention

[0005] Based on this, it is necessary to provide an automatic water purification device and a water purification method to address the problem that the descaling structure of the existing water purifier with automatic descaling function is easily blocked by scale, making it difficult to ensure the normal operation of the descaling structure.

[0006] An automatic water purification device includes a mounting frame, a filter cartridge is installed at the bottom of the mounting frame, a filter element is installed between the mounting frame and the filter cartridge, an inlet pump and an outlet pump connected to the filter cartridge are installed inside the mounting frame, and a descaling mechanism in contact with the filter element is installed inside the filter cartridge.

[0007] Furthermore, the descaling mechanism includes a threaded column rotatably connected to the inside of the filter cartridge, the surface of the threaded column is threadedly connected to a ring frame sleeved on the surface of the filter element, the inner side of the ring frame is rotatably connected to a first ring brush in contact with the filter element, the top and bottom ends of the ring frame are fixedly connected to a rubber bellows sleeved on the surface of the threaded column, the upper rubber bellows is fixedly connected between the surface of the filter cartridge and the ring frame, and the bottom of the lower rubber bellows is fixedly connected to a sealing block rotatably connected to the threaded column.

[0008] In one embodiment, a retractable rubber bellows is used in conjunction with the filter cartridge and the sealing block to form an elastic sealing structure that can follow the displacement of the ring frame and always cover the threaded column. This can not only prevent scale from adhering to the surface of the threaded column to ensure that the threaded column can always drive the first ring brush to effectively clean the filter element, but also can block the opening through which the threaded column passes to the outside of the filter cartridge, without the need to set up a separate sealing structure to ensure the isolation of the inside and outside of the filter cartridge.

[0009] Furthermore, a vertical groove is provided on the surface of the threaded column, and the descaling mechanism also includes an enhanced cleaning component, which includes an outer gear ring fixedly connected to the surface of the first ring brush, and the surface of the outer gear ring is meshedly connected with a gear sleeved on the surface of the threaded column, and the inner side of the gear is fixedly connected to a guide block slidably connected to the vertical groove.

[0010] In one embodiment, the rotation of the threaded column actively drives the first annular brush and the second annular brush to rotate during the lifting process, which can increase the friction coefficient with the inner wall of the filter element and the filter cartridge, thereby improving the cleaning effect of the filter element and the filter cartridge. In addition, there is no need to set up a separate power source for the horizontal rotation of the first annular brush and the second annular brush, which also reduces the cost of cleaning scale.

[0011] Furthermore, a second annular brush is rotatably connected to the outer side of the annular frame, and a surface of the second annular brush contacts the inner wall of the filter cartridge.

[0012] In one embodiment, this can simultaneously clean the inner wall of the filter cartridge during the lifting process, thereby improving the effective cleaning rate of scale.

[0013] Furthermore, the inner side of the second ring brush is fixedly connected to an inner gear ring, and the inner side of the inner gear ring is meshed with a gear.

[0014] In one embodiment, this can drive the second ring brush to actively rotate, thereby improving the cleaning effect on the inner wall of the filter cartridge.

[0015] Furthermore, the opposite ends of the first annular brush and the second annular brush are fixedly connected with sealing rings in contact with the annular frame, and the outer gear ring, gear, guide block and inner gear ring are all arranged between two adjacent sealing rings.

[0016] In one embodiment, this can prevent external water or dirt from entering the interior of the ring frame through the gap, thereby reducing the resistance of the first ring brush and the second ring brush to rotational cleaning.

[0017] Furthermore, a guide rod parallel to the axis of the threaded column is fixedly connected to the top of the sealing block, and the top of the guide rod passes through the outside of the ring frame.

[0018] In one embodiment, this can prevent the ring frame from rotating during the lifting process, so as to ensure that the first ring brush and the second ring brush can operate normally.

[0019] Furthermore, the number of the guide rods is two, and the two guide rods are symmetrically distributed on both sides of the axis of the threaded column.

[0020] In one embodiment, this can improve the guiding effect on the ring frame and improve the cleaning stability of the first ring brush and the second ring brush.

[0021] Furthermore, the guide rod is arranged on the inner side of the rubber bellows.

[0022] In one embodiment, this can prevent water or dirt from entering the gap between the guide rod and the ring frame, further reducing the resistance to the lifting of the first ring brush and the second ring brush.

[0023] Furthermore, the top of the threaded column passes through the filter cartridge and extends to the interior of the mounting bracket, and the top of the threaded column is fixedly connected to a servo motor that is fixedly connected to the mounting bracket.

[0024] In one embodiment, this enables workers to clean the filter element electrically, reducing the cleaning burden on the workers.

[0025] An automated water purification method comprising: 1. Connect the external water pipe to the water inlet pump in advance, then manually start the water inlet pump. The water inlet pump draws water from the outside into the filter cartridge. The filter element filters out impurities and bacteria in the water passing through. Finally, the purified water is sucked out to the outside by the water outlet pump. 2. When the user needs to regularly clean the scale adhered to the surface of the filter element, first manually turn on the servo motor. The servo motor drives the ring frame to rise and fall through the threaded column. The ring frame drives the first ring brush and the second ring brush to rise and fall to brush away the scale adhered to the surface of the filter element and the inner wall of the filter cartridge. Then, disassemble the filter cartridge and dump out the scale brushed off.

[0026] The above-mentioned automated water purification equipment uses a retractable rubber bellows in conjunction with the filter cartridge and the sealing block to form an elastic sealing structure that can follow the displacement of the ring frame and always covers the threaded column. This can not only prevent scale from adhering to the surface of the threaded column, thereby ensuring that the threaded column can always drive the first ring brush to effectively clean the filter element, but also can block the opening where the threaded column passes through to the outside of the filter cartridge, eliminating the need for a separate sealing structure to ensure the isolation between the inside and outside of the filter cartridge. The first and second ring brushes are actively driven to rotate during the lifting process by rotating the threaded column, which can increase the friction coefficient with the inner wall of the filter element and the filter cartridge, thereby improving the cleaning effect of the filter element and the filter cartridge. In addition, there is no need to set up a separate power source for the horizontal rotation of the first and second ring brushes, which also reduces the cost of cleaning scale.

[0035] The following combination Figure 1 - Figure 9 The automated water purification device of the present invention is described.

[0036] In one embodiment, an automated water purification device includes a mounting frame 100, a filter cartridge 200 mounted at the bottom of the mounting frame 100, a filter element 300 mounted between the mounting frame 100 and the filter cartridge 200, an inlet pump 400 and an outlet pump 500 mounted within the mounting frame 100 and communicating with the filter cartridge 200, and a descaling mechanism 600 mounted within the filter cartridge 200 and in contact with the filter element 300. The filter cartridge 200, the filter element 300 and the descaling mechanism 600 are used in combination and the number of used is not less than three. It should be noted that the materials of the filter element 300 are different. The specific materials need to be selected according to the needs and the order of filtering scale types. It will not be repeated here. The filter cartridge 200 includes a threaded cover fixedly connected to the bottom of the mounting frame 100. The surface of the threaded cover is threadedly connected to the carrying cylinder. The filter element 300 is inserted between the threaded cover and the carrying cylinder. The top of the threaded cover is fixedly connected and connected with a water outlet and a water inlet. The water outlet and the water inlet are respectively arranged on the inner and outer sides of the filter element 300. The inner part of the water inlet closest to the water inlet pump 400 is fixedly connected and connected with a first water guide pipe fixedly connected and connected to the water inlet pump 400. The inner part of the water outlet closest to the water outlet pump 500 is fixedly connected and connected with a second water guide pipe fixedly connected and connected to the water outlet pump 500. The inner parts of the remaining water outlets are fixedly connected and connected with a third water guide pipe connected to the adjacent water inlet on another threaded cover. The user first connects the external water pipe with the water source to the water inlet pump 400, then connects the water outlet pipe to the water outlet pump 500, and then manually controls to start the water inlet pump 400 and the water outlet pump 500 at the same time. The water inlet pump 400 transports water into the supporting cylinder through the first water pipe. At this time, the filter element 300 filters the scale in the passing water, and then the filtered water is guided into the adjacent supporting cylinder through the third water pipe. The filter element 300 in the supporting cylinder filters the scale in the passing water again, and then the filtered water is guided into the corresponding supporting cylinder by the third water pipe connected to it, until the water enters the second water pipe, and the water outlet pump 500 sucks the filtered water into the water outlet pipe for discharge.

[0037] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9As shown, the descaling mechanism 600 includes a threaded column 610 rotatably connected to the inside of the filter cartridge 200, the surface of the threaded column 610 is threadedly connected to a ring frame 620 sleeved on the surface of the filter element 300, the inner side of the ring frame 620 is rotatably connected to a first ring brush 630 in contact with the filter element 300, the top and bottom ends of the ring frame 620 are fixedly connected to a rubber bellows 640 sleeved on the surface of the threaded column 610, the upper rubber bellows 640 is fixedly connected between the surface of the filter cartridge 200 and the ring frame 620, and the bottom of the lower rubber bellows 640 is fixedly connected to a sealing block 650 rotatably connected to the threaded column 610, and the retractable rubber bellows 640 is used to cooperate with the filter cartridge 200 and the sealing block 650. 0 together form an elastic sealing structure that can follow the displacement of the ring frame 620 and always cover the threaded column 610. This can not only prevent scale from adhering to the surface of the threaded column 610, so as to ensure that the threaded column 610 can always drive the first ring brush 630 to effectively clean the filter element 300, but also can block the opening through which the threaded column 610 passes to the outside of the filter cartridge 200, without the need for a separate sealing structure to ensure the isolation between the inside and outside of the filter cartridge 200; the outer side of the ring frame 620 is rotatably connected to the second ring brush 670, and the surface of the second ring brush 670 contacts the inner wall of the filter cartridge 200, which can simultaneously clean the inner wall of the filter cartridge 200 during the lifting process, thereby improving the effective cleaning rate of scale; During the lifting and lowering process of the ring frame 620, the ring frame 620 synchronously drives the second ring brush 670 to lift and lower. The lifting and lowering of the second ring brush 670 removes the scale adhered to the inner wall of the supporting tube, which can improve the effective cleaning rate of the scale and further reduce the cleaning burden of the staff.

[0038] The top of the sealing block 650 is fixedly connected to a guide rod 680 parallel to the axis of the threaded column 610. The top of the guide rod 680 extends to the outside of the ring frame 620, which can prevent the ring frame 620 from rotating during the lifting process to ensure that the first ring brush 630 and the second ring brush 670 can operate normally. There are two guide rods 680, which are symmetrically distributed on both sides of the axis of the threaded column 610. This can improve the guiding effect on the ring frame 620 and improve the cleaning stability of the first ring brush 630 and the second ring brush 670. ; The guide rod 680 is arranged on the inner side of the rubber bellows 640, which can prevent water or dirt from entering the gap between the guide rod 680 and the ring frame 620, further reducing the resistance to the lifting and lowering of the first ring brush 630 and the second ring brush 670; the top of the threaded column 610 passes through the filter cartridge 200 and extends to the interior of the mounting bracket 100. The top of the threaded column 610 is fixedly connected to a servo motor 690 fixedly connected to the mounting bracket 100, which enables the staff to clean the filter element 300 by electricity, reducing the cleaning burden of the staff.

[0039] like Figure 5 、 Figure 6 、 Figure 8 and Figure 9 As shown, a vertical groove 611 is provided on the surface of the threaded column 610, and the descaling mechanism 600 also includes an enhanced cleaning component 660, which includes an outer gear ring 661 fixedly connected to the surface of the first annular brush 630, and the surface of the outer gear ring 661 is meshedly connected with a gear 662 sleeved on the surface of the threaded column 610, and the inner side of the gear 662 is fixedly connected with a guide block 663 slidably connected to the vertical groove 611. The rotation of the threaded column 610 actively drives the first annular brush 630 and the second annular brush 670 to rotate during the lifting process, which can increase the friction coefficient for the inner wall of the filter element 300 and the filter cartridge 200, thereby improving the cleaning effect of the filter element 300 and the filter cartridge 200, and this does not require separate first annular brush 630 and second annular brush 670. The ring brush 670 is provided with a power source for horizontal rotation, which also reduces the cost of cleaning scale; the inner side of the second ring brush 670 is fixedly connected to the inner side of the inner ring gear 664, and the inner side of the inner ring gear 664 is meshed with the gear 662, which can drive the second ring brush 670 to rotate actively, thereby improving the cleaning effect of the inner wall of the filter cartridge 200; the opposite ends of the first ring brush 630 and the second ring brush 670 are fixedly connected to the sealing ring 665 in contact with the ring frame 620, and the outer ring gear 661, the gear 662, the guide block 663 and the inner ring gear 664 are all arranged between two adjacent sealing rings 665, which can prevent external water or dirt from entering the interior of the ring frame 620 through the gap, so as to reduce the resistance of the first ring brush 630 and the second ring brush 670 to rotational cleaning; In the process of the threaded column 610 driving the ring frame 620 to rise and fall by rotating, the threaded column 610 drives the gear 662 to rotate through the vertical groove 611, and the gear 662 simultaneously drives the outer ring gear 661 and the inner ring gear 664 to rotate. The outer ring gear 661 and the inner ring gear 664 respectively drive the first ring brush 630 and the second ring brush 670 to actively rotate during the lifting process, which can increase the brushing effect of the scale on the filter element 300 and the inner wall of the supporting cylinder, so as to improve the effective removal rate of the scale.

[0040] like Figure 1-9 As shown, an automated water purification method comprises: 1. Connect the external water pipe to the water inlet pump 400 in advance, then manually start the water inlet pump 400. The water inlet pump 400 draws water from the outside into the filter cartridge 200. The filter element 300 filters out impurities and bacteria in the water. Finally, the purified water is sucked out to the outside by the water outlet pump 500. 2. When the user needs to regularly clean the scale adhered to the surface of the filter element 300, first manually turn on the servo motor 690. The servo motor 690 drives the ring frame 620 to rise and fall through the threaded column 610. The ring frame 620 drives the first ring brush 630 and the second ring brush 670 to rise and fall to brush off the scale adhered to the surface of the filter element 300 and the inner wall of the filter cartridge 200. Then, the filter cartridge 200 is disassembled and the scale brushed off is dumped away.

[0041] Working principle: When the user needs to clean the scale on the surface of the filter element 300, the user only needs to manually control to start the servo motor 690, the servo motor 690 drives the threaded column 610 to rotate back and forth, the threaded column 610 drives the ring frame 620 to rise and fall back and forth, the ring frame 620 drives the first ring brush 630 to brush back and forth to remove the scale on the surface of the filter element 300. During this process, the ring frame 620 drives the rubber bellows 640 to reciprocate and expand and contract, which can wrap the part of the threaded column 610 set on the outside of the ring frame 620, which can prevent scale from adhering to the surface of the threaded column 610, so as to ensure that the threaded column 610 can normally lift the first ring brush 630, and can perform corresponding deformation following the lifting and lowering of the ring frame 620, so as to ensure that the rubber bellows 640 can effectively cover the threaded column 610 at the corresponding length.

[0042] It should be noted that the filter element 300, the water inlet pump 400 and the water outlet pump 500 in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the water inlet pump 400 and the water outlet pump 500 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0043] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of the present invention. Therefore, the scope of the present invention shall be determined by the appended claims.
