A water purifier with anti-drip function

Abstract

The utility model relates to the technical field of water purifiers, and in particular to a water purifier with an anti-drip function. When a filter element is installed in an integrated water circuit mechanism, a small cylindrical convex column can conflict with a water stop valve opening and closing structure and press down a piston rod of the water stop valve, so that the water stop valve opening and closing structure and the water stop valve are in an open state. At the same time, a water outlet push rod of the filter element is inserted into the small cylindrical convex column to open the water stop valve in the cylindrical convex column. When the filter element is disassembled from the integrated water circuit mechanism, the water stop valve piston rod loses the pressure of the filter element, and the water stop valve piston rod is reset under the action of a reset spring, so that the water stop valve and the water stop valve opening and closing structure are restored to a closed state. At the same time, the water stop valve in the cylindrical convex column loses the conflicting pressure of the filter element water outlet push rod, and the water stop valve is closed. Therefore, even if the water inlet source is not closed, it can prevent a large amount of water from dripping into the water purifier or onto the ground when the filter element is disassembled and assembled, thereby improving the automatic water stopping and anti-drip function of the water purifier and improving the convenience of disassembling and assembling and maintaining the water purifier.

[0002] With the progress of industrialization and urbanization, water resources have been polluted to varying degrees, including the presence of heavy metals, bacteria, viruses, parasites and other pollutants, which has made people increasingly concerned about the safety of drinking water; therefore, people's pursuit of a healthy life has promoted the emergence and development of water purifiers. At the same time, with the improvement of living standards and the enhancement of health awareness, people are paying more and more attention to the quality and taste of drinking water. Water purifiers just meet this demand and provide people with healthier and safer drinking water.

[0003] Many of the existing water purifiers that use multi-stage purification technology use hoses or adapters to connect the water supply channel to pass water to the filter element. Since the water purifier has many filtration stages and also has more water channel components, more hoses or adapters are needed to connect the inside of the water purifier. This makes the inside of the water purifier messy, large in size, with many interfaces, and prone to aging of seals. In addition, the hose and filter element will leak when the filter element is disassembled and assembled, which makes the production, installation and subsequent maintenance of the water purifier more troublesome.

[0053] In order to solve the problems raised in the above background technology, the inventor has designed a water purifier with anti-drip function after in-depth research. Figures 1 to 31 As shown, a detailed explanation is given.

[0054] In this embodiment, a decorative cover 1 for decoration and dust prevention is provided at the front end of the water purifier. A penetrating light guide column hole 11 is provided at the middle position of the upper part of the decorative cover 1. After a conventional light guide column is installed at the light guide column hole 11, the light effect of the indicator light on the main control board can be synchronously displayed on the outside of the decorative cover 1 without connecting wires. The decorative cover 1 is fixed by magnets, which has the advantages of convenient installation and disassembly. A plurality of magnet installation grooves 12 are provided on the side of the decorative cover 1, and magnets are installed in the magnet installation grooves 12. In order to reduce the deformation of the decorative cover 1 after injection molding, a plurality of reinforcing ribs 13 are also provided on the inner side thereof. In order to facilitate users to open the decorative cover 1, an arc-shaped hand-holding position 14 is also provided on the inner side of the middle position of the lower edge thereof.

[0055] As an improved specific implementation, the outermost layer of the filter element 2 is a filter barrel 21 and a filter barrel cover 22, which can be connected by conventional threads or welding. The upper part of the filter barrel 21 is a cylindrical filter barrel cylinder 2101, whose internal cavity is a cylindrical inner cavity 2105 for placing the filter element, and the middle part of the lower end surface of the filter barrel cylinder 2101 coaxially extends downward to form a large cylindrical protrusion 2102, a middle cylindrical protrusion 2103 and a small cylindrical protrusion 2104 with successively smaller diameters, and the upper end surface of the filter barrel cylinder 2101 also coaxially extends upward to form a section of an annular connecting bone 2106 for connecting the filter barrel cover 22.

[0056] Furthermore, two connection positions 2107 and a positioning point 2108 for clamping the filter element fixing seat 43 are radially arranged at the lower part of the outer wall of the large cylindrical boss 2102, and the two connection positions 2107 are distributed at 180 degrees. The setting of the positioning point 2108 allows the user to install the filter element 2 without deliberately aligning it. The filter element 2 can be inserted into the filter element installation cylinder 302 at will and rotate the filter element 2 clockwise after the filter element 2 is against the upper plane of the filter element fixing seat 43. After the positioning point 2108 and the installation directional bayonet 4312 are automatically overlapped, the filter element 2 can be quickly clamped on the filter element fixing seat 43 by turning it again, thereby improving the installation efficiency of the filter element. The inner cavity of the large cylindrical boss 2102 is also coaxially provided with a cylindrical partition installation groove 2112, and the filter barrel partition 24 is installed in the partition installation groove 2112.

[0057] Furthermore, a plurality of radial cylindrical reinforcement ribs 2111 are provided on the inner plane where the filter barrel cylinder 2101 and the large cylindrical boss 2102 are connected. The cylindrical reinforcement ribs 2111 can increase the strength of the filter barrel 21 on the one hand, and can also support the accessories inside the filter barrel 21 on the other hand, to prevent the accessories from sinking to the bottom plane of the filter barrel cylinder 2101 and thereby hindering the flow of tap water into the filter element.

[0058] Further, a plurality of middle convex column sealing ring grooves 2109 are arranged on the outer wall of the middle convex column 2103 of the cylinder, and a filter cover connecting hole 2113 and a water stop valve mounting hole 2114 are arranged in sequence from top to bottom on the inner cavity plane of the middle convex column 2103 of the cylinder. In order to introduce tap water into the interior of the filter element 2, a plurality of penetrating filter element water inlet holes 2115 are arranged on the bottom plane of the middle convex column 2103 of the cylinder, and the filter element water inlet holes 2115 connect the inner cavity 2105 of the cylinder with the external space of the filter element 2.

[0059] Furthermore, a plurality of filter cover connection hole reinforcing ribs 2116 are radially arranged between the inner wall of the cylindrical protrusion 2103 and the outer wall of the filter cover connection hole 2113 .

[0060] Furthermore, a plurality of small boss sealing ring grooves 2110 are provided on the outer wall of the small cylindrical boss 2104, and a penetrating filter element water outlet hole 2117 is also axially provided at the center of the small cylindrical boss 2104. The filter element water outlet hole 2117 is connected with the water stop valve mounting hole 2114, the filter cover connecting hole 2113 and the cylindrical inner cavity 2105 in sequence. The tap water flowing into the filter element is purified by the filter element 2 and then flows out from the filter element water outlet hole 2117.

[0061] As an improved specific implementation method, the lower end of the filter barrel cover 22 is a cylindrical filter barrel cover body 221, one end of the filter barrel cover body 221 is closed and the other end is open, a runway-shaped filter barrel cover handle 222 extends outward from the plane of the closed end, and a connecting groove 223 for connecting the filter barrel 21 is provided on the side wall of the open end, and a plurality of filter barrel cover reinforcement ribs 224 are also provided in the inner cavity of the filter barrel cover 22.

[0062] As an improved specific implementation, the filter barrel partition 24 is set to be a hollow cylinder, and the middle hole is a penetrating partition hole 241. When assembled, the small water outlet cover protrusion 254 on the filter element water outlet cover 25 passes through the partition hole 241 and is sealed and connected to the inner wall of the partition hole 241 through the sealing ring at the inner sealing ring groove 255. A water stop valve fixing hole 242 is also provided between the partition hole 241 and the inner wall of the filter barrel partition 24. Furthermore, multiple water stop valves 242 are provided on the outer wall of the filter barrel partition 24. There is a partition sealing ring groove 243. When assembling, the filter barrel partition 24 is sealed and connected to the side wall of the partition mounting groove 2112 through the sealing ring on the partition sealing ring groove 243. The sealing effect of the sealing ring on the partition sealing ring groove 243, the sealing ring on the inner sealing ring groove 255 and the water stop valve on the water stop valve fixing hole 242 can effectively prevent the water remaining between the outer wall of the filter element cylinder 261 and the inner wall of the filter barrel 21 from dripping onto the ground when the used filter element is disassembled, thereby reducing unnecessary trouble.

[0063] Furthermore, a C-shaped blocking ring 244 is axially extended downward on the lower end surface of the filter barrel partition 24. The opening of the C-shaped blocking ring 244 is a blocking ring water gathering port 245, and the blocking ring water gathering port 245 is arranged on a side close to the water stop valve fixing hole 242. The blocking ring water gathering port 245 serves to gather water flow, that is, when tap water enters the lower part of the filter element from the filter element water inlet hole 2115, when it encounters the C-shaped blocking ring 244, all of the water is gathered together and then flows out from the blocking ring water gathering port 245. The concentrated water flow is more conducive to flushing open the water stop valve installed on the filter barrel partition 24, and finally passes through the water stop valve and flows into the cylindrical cavity 2105.

[0064] As an improved specific implementation method, the big end of the filter element water outlet cover 25 is a cylindrical water outlet cover body 251, and a large water outlet cover boss 252 is axially extended outward from one side of the large plane of the water outlet cover body 251. A plurality of boss reinforcement ribs 253 are radially arranged on the side wall of the large water outlet cover boss 252, and a small water outlet cover boss 254 is axially extended at the outer plane of the large water outlet cover boss 252. Further, an inner sealing ring groove 255 and an outer sealing ring groove 256 are respectively arranged on the outer wall of the small water outlet cover boss 254 from the inner end to the outer end. The inner cavities of the filter element water outlet cover 25, the large water outlet cover boss 252 and the small water outlet cover boss 254 are connected to form a water outlet cover water outlet hole 257, and the water purified by the filter element 2 flows out from the water outlet cover water outlet hole 257.

[0065] Furthermore, an annular water outlet cover positioning ring 258 is extended inward from the inner middle part of the large plane of the filter element water outlet cover 25. The positioning ring 258 can position the rod-shaped filter material 27 installed in the filter element water outlet cover 25 at the center of the filter element housing 26, thereby improving the reliability of the filter element during operation. A water outlet cover connecting thread 259 is also provided on the inner wall of the filter element water outlet cover 25 for connecting to the end thread of the filter element housing 26.

[0066] As an improved specific implementation method, the filter element housing 26 is a hollow cylinder for filling the rod-shaped filter material 27, the middle part of which is the filter element cylinder 261, and the internal cavity is the filter element inner cavity 262. The two ends of the filter element housing 26 are respectively provided with a filter element thread 263 for connecting the filter element water outlet cover 25 and the filter element water inlet cover 29. Furthermore, a filter element sealing ring groove 264 is also provided on the outer wall where the filter element cylinder 261 and the filter element thread 263 are connected. The sealing ring on the filter element sealing ring groove 264 can make the filter element water outlet cover 25 and the filter element water inlet cover 29 sealed and connected to the filter element housing 26.

[0067] As a specific implementation of the improvement, the rod-shaped filter material 27 is generally a hollow rod-shaped body formed by compounding one or more filter materials and undergoing conventional processing. The outside of the rod-shaped filter material 27 is a filter material body 271, and a filter material inner hole 272 is arranged in the middle of the filter material body 271. After the tap water flows from the outer wall of the filter material body 271 to the inner wall, the impurities in the water will be adsorbed or retained by the filter material body 271, and the tap water can be purified. The purified tap water is collected in the filter material inner hole 272 and then flows out through the water outlet hole 257 of the water outlet cover 25 of the filter element.

[0068] As an improved specific implementation, the filter element plug 28 is designed to be flange-like and made of ordinary plastic to seal the open port of the rod-shaped filter material 27. A plug recess 281 is designed in the middle of the filter element plug 28.

[0069] As an improved specific implementation method, the filter element water inlet cover 29 is arranged in a cylindrical shape, and a water inlet cover main plane 291 is arranged at one end of the filter element water inlet cover 29, and a 7-shaped upper edge 292 is extended outward from the outside of the water inlet cover main plane 291, and a plurality of penetrating fan-shaped water inlet grooves 293 and a plurality of upper edge reinforcement ribs 294 are arranged directly below the 7-shaped upper edge 292. During operation, tap water enters the gap between the inner wall of the filter element housing 26 and the outer wall of the rod-shaped filter material 27 from the fan-shaped water inlet groove 293, and then is filtered by the rod-shaped filter material 27 and collected at the filter material inner hole 272 in the middle of the rod-shaped filter material 27, and finally flows out from the water outlet cover water outlet hole 257 of the filter element water outlet cover 25. Furthermore, an intermediate boss 295 is axially extended inward from the inner side of the main plane 291 of the water inlet cover. During assembly, the intermediate boss 295 will be inserted into the plug recess 281 in the middle of the filter plug 28 to ensure that the rod-shaped filter material 27 is in the middle of the filter element when installed, thereby improving the stability of the filter element during operation. A water inlet cover thread 296 for connecting the filter element housing 26 is provided on the inner wall of the filter element water inlet cover 29, and a plurality of ultrasonic welding lines 297 for welding PP cotton filter screens are also provided on the inner plane of the main plane 291 of the water inlet cover. After welding a layer of PP cotton filter screen here, the water entering the filter element can be initially filtered, thereby extending the service life of the filter element.

[0070] As a specific implementation of the improvement, the main frame bracket 3 is mainly used as the supporting skeleton of the entire water purifier. A bracket upper plate 301 is arranged at the top of the main frame bracket 3. According to the needs of the purification filter level of the water purifier, multiple filter element mounting cylinders 302 are arranged in the vertical downward direction of the bracket upper plate 301.

In order to facilitate installation and reduce the volume of the integrated waterway mechanism 4, the internal water delivery channel of the main component integrated waterway plate 41 is designed in a stacked manner; the middle position of the upper plane of the integrated waterway plate 41 is linearly arranged with a first-level water inlet hole 4101, a first-level water outlet hole 4102, a second-level water inlet hole 4103, a second-level water outlet hole 4104, a third-level water inlet hole 4105 and a third-level water outlet hole 4106, and the water inlet and outlet holes of the same level correspond to the water inlet and outlet of the filter element 2 of the same level, that is, the first-level inlet hole 4101, the first-level water outlet hole 4102, the second-level water inlet hole 4103, the second-level water outlet hole 4104, the third-level water inlet hole 4105 and the third-level water outlet hole 4106. The water hole 4101 is connected to the water inlet 4110 of the waterway plate through the first water transfer channel 4115, so that the tap water is input from the quick-connect connector 44 at the water inlet 4110 of the waterway plate and then transported through the first water transfer channel 4115 to reach the input port of the primary filter element, and then flows out from the primary water outlet hole 4102 after being purified by the primary filter element, and then transported through the second water transfer channel 4116 to the secondary filter element for purification, and so on. The tap water can be purified by the multi-stage filter element 2 and then flow out from the water outlet 4111 of the waterway plate. After the multi-stage filter elements are connected in series, multi-stage purification of tap water can be achieved, thereby improving the filtering accuracy of the water purifier.

[0076] Furthermore, a plurality of fixing seat installation columns 4107 and foolproof columns 4108 are arranged on the upper plane of the integrated waterway plate 41 and around the water inlet and outlet holes at various levels. The foolproof columns 4108 will hinder the insertion of the filter element fixing seat 43 when it is inserted into the water inlet and outlet holes at various levels in the reverse direction, thereby preventing the filter element fixing seat 43 from being installed in reverse. A plurality of bracket connecting columns 4109 for connecting the main frame bracket 3 are also arranged near the edges of the upper plane of the integrated waterway plate 41. The distribution of the bracket connecting columns 4109 corresponds to the bracket fixing holes 312 on the main frame bracket 3.

[0077] Furthermore, a waterway plate water inlet 4110 and a waterway plate water outlet 4111 are provided on the left end side of the integrated waterway plate 41. The waterway plate water inlet 4110 is used to install a quick-plug connector 44 for inputting tap water, and the waterway plate water outlet 4111 is used to install a quick-plug connector 44 for outputting purified water. In order to reduce the connection ports of the water purifier to facilitate the assembly of the water purifier and injection molding, water channel sealing ports 4112 that can be quickly sealed are also provided at multiple ports of the water delivery channel.

[0078] In order to further realize the flow monitoring function of the integrated water channel mechanism 4, a Hall detector mounting groove 4113 is arranged next to one end of the first water supply channel 4115, and the Hall detector 46 of the flowmeter is fixed at the Hall detector mounting groove 4113 by screws, and the flowmeter rotor 45 is installed at the flowmeter rotor mounting groove 4120 in the port of the first water supply channel 4115, and the positions of the flowmeter rotor 45 and the Hall detector 46 match.

[0079] Furthermore, a plurality of rear cover connecting columns 4114 for connecting to the main unit rear cover 6 are provided on the bottom surface of the integrated water circuit board 41, and the distribution of the rear cover connecting columns 4114 matches the rear cover screw holes 61 on the main unit rear cover 6; a group of magnetizer mounting grooves 4119 are provided in the middle position of the bottom surface of the integrated water circuit board 41, and a water quality magnetizer 48 for activating water quality is installed in the magnetizer mounting groove 4119, and the magnetizer mounting groove 4119 is provided on the left and right sides of the last-stage water transfer channel.

[0080] Further, a first water delivery channel 4115, a second water delivery channel 4116, a third water delivery channel 4117 and a third water delivery channel 4118 are provided inside the integrated waterway plate 41. The first water delivery channel 4115 is composed of a first transverse channel 4115A, a second transverse channel 4115B and a vertical channel 4115C. The first transverse channel 4115A is located at the lower layer of the integrated waterway plate 41, the second transverse channel 4115B is located at the upper layer of the integrated waterway plate 41, and the vertical channel 4115C is located at the middle layer of the integrated waterway plate 41. The first transverse channel 4115A and the second transverse channel 4115B are distributed in a transverse manner, and the vertical channel 4115C is distributed in a longitudinal manner. The vertical channel 4115C is located at the upper layer. The end of the first transverse channel 4115A section and the front end of the second transverse channel 4115B section of the lower layer are connected together to form a complete first water transfer channel 4115. The first water transfer channel 4115 is used to transfer tap water to the water inlet of the first-level filter element, the second water transfer channel 4116 is used to transfer water purified by the first-level filter element to the water inlet of the second-level filter element, the third water transfer channel 4117 is used to transfer water purified by the second-level filter element to the water inlet of the tertiary filter element, and so on. The third water transfer channel 4118 is used to transfer water purified by the tertiary filter element to the water outlet 4111 of the waterway plate, and then it is controlled by the water outlet faucet for users to use. Of course, the filter element level and water transfer channel can also be set according to actual needs.

[0081] Furthermore, in order to ensure that each water delivery channel has good sealing performance, after the integrated waterway plate 41 is injection molded, each water channel sealing opening 4112 needs to be sealed with a plugging cover. The water channel sealing opening 4112 cover is provided with a weld-free plugging cover 42 that can be quickly installed to prevent water leakage.

[0082] As an improved specific implementation method, the welding-free plugging cover 42 is designed to be a hollow cylinder similar to a T-shape and closed at one end, and its large head end is the plugging cover body 421. A circle of plugging cover claws 422 are radially arranged on the middle side wall of the plugging cover body 421. In order to make the welding-free plugging cover 42 easy to install and have good firmness, the plugging cover claws 422 are made of metal plates with good hardness and elasticity such as stainless steel sheets with a thickness of less than 1 mm and are embedded in the side wall of the plugging cover body 421 through an injection molding process, and a plugging cover sealing ring 423 is arranged at the small head end of the plugging cover body 421. When assembling, it is only necessary to press the welding-free plugging cover 42 into the water channel blocking port 4112, and the plugging cover claws 422 will be firmly clamped on the inner wall of the water channel blocking port 4112, and then the water channel blocking port 4112 can be sealed by the sealing effect of the plugging cover sealing ring 423, which can avoid the trouble of welding of common plugging covers.

[0083] As an improved specific implementation method, the filter element fixing seat 43 is an accessory used to fix the filter element 2 and connect the water inlet and outlet interfaces of the filter element 2. The filter element fixing seat 43 is cylindrical as a whole. The upper part of the filter element fixing seat 43 is the fixing seat body 4301. Two fan-shaped fixing seat clamping positions 4302 for clamping the filter element 2 are arranged on the inner wall of the port at the upper end of the fixing seat body 4301, and the two fixing seat clamping positions 4302 are distributed at an angle of 180 degrees on the inner wall of the fixing seat body 4301. A filter element clamping strip 4303 and a filter element stop baffle 4304 are axially arranged on the inner wall below one of the fixing seat clamping positions 4302. Furthermore, a downwardly extending clamping guide slope 4305 is arranged at the clockwise end of each fan-shaped fixing seat clamping position 4302. The clamping guide slope 4305 plays a guiding role when disassembling and assembling the filter element 2.

[0084] Furthermore, in the present embodiment, the filter element 2 can be configured to be disassembled and assembled in a rotating manner. When the filter element 2 is inserted into the filter element mounting cylinder 302 of the main frame bracket 3 and rotated clockwise, the filter element 2 will slide along the positioning guide inclined surface 4305 until the front end surface of one of the connecting positioning positions 2107 on the filter element 2 just contacts the filter element stop baffle 4304, and the upper plane of the connecting positioning position 2107 is just clamped on the lower plane of the fixing seat positioning position 4302, and at the same time, the groove on the outer surface of the connecting positioning position 2107 on the filter element 2 close to the filter element clamping strip 4303 is also just clamped on the filter element clamping strip 4303, thereby achieving the fixation of the filter element 2. On the contrary, when the filter element 2 rotates counterclockwise, the filter element 2 first separates from the filter element clamping strip 4303, and then slides upward along the positioning guide inclined surface 4305, and finally the filter element 2 can be disassembled after it is completely separated from the fixing seat positioning position 4302.

[0085] Furthermore, a large fixing seat ring 4306 and a small fixing seat ring 4308 are axially arranged upward at the middle position of the inner plane of the filter element fixing seat 43, and the large fixing seat ring 4306 is higher than the small fixing seat ring 4308. The large fixing seat ring 4306 is used to sleeve the cylindrical middle convex column 2103 on the filter element 2, and the small fixing seat ring 4308 is used to sleeve the cylindrical small convex column 2104 on the filter element 2.

[0086] Furthermore, a water stop valve push rod hole 4307 is provided between the inner wall of the fixed seat large ring 4306 and the outer wall of the fixed seat small ring 4308 and at the same height as the fixed seat small ring 4308. An opening and closing structure mounting hole 4318 is also extended axially downward directly below the water stop valve push rod hole 4307. The water stop valve push rod hole 4307 is respectively connected to the opening and closing structure mounting hole 4318 and the inner cavity of the fixed seat large ring 4306. During assembly, the water stop valve opening and closing structure 49 is installed in the opening and closing structure mounting hole 4318.

[0087] Further, a filter element water outlet push rod 4309 is axially arranged upward at the center of the inner plane of the filter element fixing seat 43. When the filter element 2 is installed in place, the filter element water outlet push rod 4309 will push open the piston of the water stop valve 23 installed at the water stop valve installation hole 2114. At this time, the purified water stored in the filter material inner hole 272 in the middle of the rod-shaped filter material 27 can flow out of the filter element 2 through the water stop valve 23. When the filter element 2 is removed from the filter element fixing seat 43, there is no thrust of the filter element water outlet push rod 4309, and the piston of the water stop valve 23 is closed. In this way, the purified water remaining in the filter material inner hole 272 in the middle of the filter element will not drip onto the ground, thereby reducing unnecessary trouble. Further, a fixed seat water outlet hole 4310 is arranged on the inner plane of the filter element fixing seat 43 at a place corresponding to the axis of the fixed seat water outlet column hole 4317, and the fixed seat water outlet hole 4310 is connected with the fixed seat water outlet column hole 4317.

[0088] Furthermore, two filter element supporting blocks 4311 are arranged on the inner wall of the filter element fixing seat 43 and at a position matching the rotation trajectory of the filter element 2, and the two filter element supporting blocks 4311 are distributed at an angle of 180 degrees. The filter element supporting blocks 4311 can support the lower plane of the connecting position 2107 on the filter element 2 when the filter element 2 is rotated for disassembly or installation, thereby making the disassembly and assembly of the filter element 2 smoother.

[0089] Furthermore, an installation directional bayonet 4312 is provided at the middle position of the fixed seat clamp 4302 away from the filter element stop baffle 4304. When installing the filter element 2, it is only necessary to insert it into the bottom of the filter element installation cylinder 302 and rotate it until the alignment clamping point 2108 coincides with the installation directional bayonet 4312. Then, the filter element 2 can be rotated to slide along the clamping guide slope 4305 to rest against the filter element stop baffle 4304, thereby realizing quick and reliable installation of the filter element 2. The installation directional bayonet 4312 allows the user to install the filter element 2 without deliberately aligning it, making the installation of the filter element 2 more convenient and quick.

[0090] Furthermore, a plurality of fixing seat screw holes 4313 are provided on the bottom plane of the filter element fixing seat 43, and the distribution of the fixing seat screw holes 4313 matches the fixing seat mounting column 4107 on the integrated waterway plate 41, so that the filter element fixing seat 43 can be fixed to the fixing seat mounting column 4107 by screws.

[0091] Furthermore, a fixed seat water inlet column 4314 is coaxially arranged downwardly below the opening and closing structure mounting hole 4318, and the inner cavity of the fixed seat water inlet column 4314 is provided with a fixed seat water inlet column hole 4315, and the fixed seat water inlet column hole 4315 is connected with the opening and closing structure mounting hole 4318. During assembly, a water stop valve 23 is also installed at the fixed seat water inlet column hole 4315. When the water stop valve 23 here is opened, water can flow into the filter element 2. On the contrary, when the water stop valve 23 here is closed, water will be prevented from flowing into the filter element 2.

[0092] Furthermore, a fixed seat water outlet column 4316 is axially arranged downward below the fixed seat water outlet hole 4310, and the inner cavity of the fixed seat water outlet column 4316 is provided with a fixed seat water outlet column hole 4317. The fixed seat water outlet column hole 4317 is connected with the fixed seat water outlet hole 4310. During assembly, a water stop valve 23 is installed at the fixed seat water outlet column hole 4317. When the water stop valve 23 here is opened, the purified water stored in the filter material inner hole 272 inside the filter element 2 can flow out of the filter element 2. On the contrary, when the water stop valve 23 here is closed, the purified water at the filter material inner hole 272 inside the filter element will be prevented from flowing out of the filter element 2.

[0093] As an improved specific implementation, the magnetizer cover 47 is installed above the magnetizer installation slot 4119 on the integrated waterway plate 41 to fix the water quality magnetizer 48.

[0094] As an improved specific implementation method, the water stop valve opening and closing structure 49 is used to control the opening or closing of the water stop valve 23 installed in the water inlet column hole 4315 of the fixed seat; the lower part of the water stop valve opening and closing structure 49 is a flange-shaped opening and closing structure base 491, the middle part is a reset spring 492, and the upper part is a water stop valve piston rod 493; during assembly, the bottom of the opening and closing structure base 491 is against the top plane of the water stop valve 23, and the lower end of the water stop valve piston rod 493 passes through the reset spring 492 and the center hole of the opening and closing structure base 491; after the filter element 2 is installed in place, the lower plane of the small cylindrical protrusion 2104 of the filter element will push the water stop valve The piston rod 493 is pressed downward, and then the lower end of the water stop valve piston rod 493 pushes open the piston of the water stop valve 23, so that water can flow out from the integrated water circuit mechanism 4 and pass through the water stop valve 23 and enter the filter element 2. On the contrary, when the filter element 2 is removed, the water stop valve piston rod 493 will move upward and reset under the elastic force of the reset spring 492, so that the piston of the water stop valve 23 loses thrust and returns to a closed state. At this time, water cannot flow out of the integrated water circuit mechanism 4, thereby preventing water from dripping into the water purifier or onto the ground when the filter element 2 is disassembled and assembled, thereby improving the anti-drip function of the water purifier during disassembly and assembly.

[0095] As an improved specific implementation, the main body shell 5 is arranged on the outside of the water purifier, and a plurality of shell support bones 51 for supporting the main body bracket 3 and the main body back cover 6 are arranged on the inner walls around the main body shell 5. The front end of each shell support bone 51 is provided with a front end slot 52 for clamping the main body bracket 3, and the rear end is provided with a rear end slot 53 for clamping the main body back cover 6. A plurality of shell support feet 54 for supporting the entire water purifier are also arranged on the lower surface of the main body shell 5.

[0096] As an improved specific implementation method, the main unit rear cover 6 is arranged at the rear end of the water purifier, and a plurality of rear cover screw holes 61 are arranged on the plane of the main unit rear cover 6. The distribution of the rear cover screw holes 61 matches the distribution of the rear cover connecting columns 4114 on the integrated water circuit plate 41. Furthermore, two penetrating quick-connector extension holes 62 and a penetrating indicator light connector mounting hole 63 are further arranged at the upper end of the main unit rear cover 6. The distribution of the quick-connector extension holes 62 matches the position of the quick-connector 44 on the integrated water circuit mechanism 4.

[0097] Furthermore, a plurality of bottom cover reinforcement ribs 64 are provided on the inner plane of the main unit rear cover 6. The outermost circle of reinforcement ribs on the inner plane of the main unit rear cover 6 not only serves to enhance the strength of the main unit rear cover 6, but also can be used as snap-fitting positions connected to the main unit housing 5. When the main unit rear cover 6 is assembled to the main unit housing 5, the outermost circle of bottom cover reinforcement ribs 64 of the main unit rear cover 6 is just fastened to the rear end slot 53 of the main unit housing 5, thereby ensuring that the main unit housing 5 will not deform outwards, thereby increasing the reliability and firmness of the water purifier.

[0098] The above is only a preferred implementation of the present invention, and the protection scope of the present invention is not limited to the above embodiments. Several improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
