[0040] In order to solve the problems raised in the above background technology, the inventor has designed an integrated water channel structure of a water purifier after in-depth research. The integrated water channel structure of the water purifier provided by the present application is explained in detail below in conjunction with the accompanying drawings.

[0041] like Figures 1 to 10 As shown, an integrated waterway structure of a water purifier includes: an integrated waterway plate 41, which is provided with a first water supply channel 4115, a second water supply channel 4116 and a third water supply channel 4117 connected in a stacked manner; a filter element fixing seat 43, which is sequentially installed on the integrated waterway plate 41 and is parallel to each other, a first filter element fixing seat 431, a second filter element fixing seat 432 and a third filter element fixing seat 433; quick-plug connectors 44, at least two of which are installed on the integrated waterway plate 41; wherein the first water supply channel 4115 is respectively connected to the first filter element fixing seat 431 and the quick-plug connector 44, the second water supply channel 4116 is respectively connected to the second filter element fixing seat 432 and the third filter element fixing seat 433, and the third water supply channel 4117 is respectively connected to the third filter element fixing seat 433 and the quick-plug connector 44.

[0042] Through the above scheme, a stacked integrated water channel with multi-stage filtration can be formed, eliminating hoses or adapters, reducing the size of the water purifier, and making it easier to disassemble and assemble.

[0043] As an improved specific implementation, the integrated waterway plate 41 is provided with a first water delivery channel 4115, a second water delivery channel 4116, and a third water delivery channel 4117. The first water delivery channel 4115 is composed of three sections 4115A, 4115B, and 4115C, wherein 4115A is located at the lower layer of the integrated waterway plate 41, 4115B is located at the upper layer of the integrated waterway plate 41, and 4115C is located at the middle layer of the integrated waterway plate 41, and sections 4115A and 4115B are distributed horizontally, and section 4115C is distributed vertically; section 4115C connects the upper layer 4115A to the middle layer 4115C. The end of the 5A section channel and the beginning of the lower layer 4115B section channel 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-stage filter element; the second water transfer channel 4116 is used to transfer water purified by the first-stage filter element to the water inlet of the second-stage filter element; the third water transfer channel 4117 is used to transfer water purified by the second-stage filter element to the water inlet of the third-stage filter element, and so on. Finally, the water purified by the multi-stage filter element is transferred to the water outlet 4111 of the waterway plate, and then provided to the user through the control of the water outlet faucet.

[0044] Through the above scheme, the first water supply channel 4115, the second water supply channel 4116, and the third water supply channel 4117 are set inside the integrated water circuit plate 41, so that tap water can be transported to the corresponding multi-stage filter element for purification through N water supply channels, ensuring the circulation of internal water and reducing the volume of the water purifier.

[0045] As a specific implementation method of the improvement, the integrated waterway structure is the main mechanism for water flow transportation and on-off control inside the water purifier; the internal water supply 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 same first-level filter element; in this embodiment, a three-level filter element can be correspondingly arranged to achieve multi-stage filtration, that is, the first-level water inlet hole 4101 is connected to the waterway plate water inlet 4110 through the first water supply channel 4115, In this way, after the tap water is input from the quick-connect connector 44 at the water inlet 4110 of the water circuit plate, it can be transported through the first water supply channel 4115 to reach the input port of the first-stage filter element, and then flow out from the first-stage water outlet hole 4102 of the integrated water circuit plate 41 after being purified by the first-stage filter element; then it is transported through the second water supply channel 4116 to reach the input port of the second-stage filter element, and then flow out from the second-stage water outlet hole 4104 of the integrated water circuit plate 41 after being purified by the second-stage filter element; then it is transported through the third water supply channel 4117 to reach the input port of the third-stage filter element, and then flow out from the third-stage water outlet hole 4106 of the integrated water circuit plate 41 after being purified by the third-stage filter element; multiple levels of purification are carried out, and so on. Of course, the filtration levels can be set according to actual needs.

[0046] Through the above scheme, multi-stage filter elements can be connected in series to achieve multi-stage purification of tap water, thereby improving the filtering accuracy of the water purifier.

[0047] As an improved specific implementation method, a plurality of fixing seat mounting columns 4107 and foolproof columns 4108 are also provided on the upper plane of the integrated water circuit board 41 and around the water inlet and outlet holes at each level; 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 each level in the reverse direction left and right, thereby preventing the filter element fixing seat 43 from being installed upside down. A plurality of bracket connecting columns 4109 for connecting the main frame bracket are also provided on the upper plane of the integrated water circuit board 41 near the edges on all sides; the distribution of the bracket connecting columns 4109 corresponds to the fixed structure on the main frame bracket. A water circuit board water inlet 4110 and a water circuit board water outlet 4111 are also provided on the left end side of the integrated water circuit board 41; the water circuit board water inlet 4110 is used to install the quick-connect connector 44 for inputting tap water, and the water circuit board water outlet 4111 is used to install the quick-connect connector 44 for outputting purified water.

[0048] As an improved specific implementation method, in order to realize the flow monitoring function of the integrated waterway structure, a Hall detector mounting groove 4113 is arranged next to one end of the first water transfer channel 4115, and the Hall detector 46 of the flowmeter can be fixed at the Hall detector mounting groove 4113 by screws; the flowmeter rotor 45 is installed at the flowmeter rotor mounting groove 4120 in the port of the first water transfer channel 4115, and the positions of the flowmeter rotor 45 and the Hall detector 46 match; a plurality of rear cover connecting columns 4114 for connecting the rear cover are also arranged on the bottom surface of the integrated waterway plate 41, and the distribution of the rear cover connecting columns 4114 matches the fixing holes on the rear cover to realize the sealed installation of the integrated waterway plate 41; a group of magnetizer mounting grooves 4119 are arranged in the middle position of the bottom surface of the integrated waterway plate 41, and the water quality magnetizer 48 for activating the water quality is installed at the magnetizer mounting groove 4119, and the magnetizer mounting groove 4119 is arranged on the left and right sides of the last-level water transfer channel.

[0049] As an improved specific implementation method, in order to simplify the assembly process and the needs of injection molding, a plurality of water channel sealing ports 4112 are arranged at the ports connected to the water channels around the integrated water channel plate 41; further, in order to ensure that each water channel has good sealing performance, each water channel sealing port 4112 needs to be sealed after the injection molding of the integrated water channel plate 41 is completed; further, each water channel sealing port 4112 is fixedly installed with a welding-free plugging cover 42, so that it can be quickly installed or disassembled.

[0050] 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; its large head end is the plugging cover body 421, and 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; 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, thereby avoiding the trouble of welding of common plugging covers.

[0051] As an improved specific implementation method, the filter element fixing seat 43 is an accessory used to fix the filter element and connect the water inlet and outlet interfaces of the filter element with the water inlet and outlet of the integrated water circuit plate 41. The filter element fixing seat 43 is cylindrical as a whole, and its upper part is the fixing seat body 4301; two fan-shaped fixing seat clamping positions 4302 for clamping the filter element 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 on the inner wall of the fixing seat body 4301 at an angle of 180 degrees; a filter element clamping strip 4303 and a filter element stop baffle 4304 are axially arranged on the inner wall of the fixing seat body 4301 below one of the fixing seat clamping positions 4302; further, 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.

[0052] As an improved specific implementation method, the filter element can be disassembled and assembled in a rotating manner in conjunction with the fixing structure of the filter element fixing seat 43. When the filter element is inserted and rotated clockwise, the filter element will slide along the positioning guide inclined surface 4305 until the front end surface of the clamping column on the filter element just contacts the filter element stop baffle 4304, and the upper plane of the clamping column is just clamped on the lower plane of the fixing seat clamping position 4302. At the same time, the groove on the outer surface of the clamping column on the side of the filter element close to the filter element clamping strip 4303 is also just clamped on the filter element clamping strip 4303, thereby achieving fixed installation of the filter element. Of course, the clamping column structure of the filter element can be specifically set according to actual needs; on the contrary, when the filter element rotates counterclockwise, the filter element first separates from the filter element clamping strip 4303, and then slides upward along the positioning guide inclined surface 4305, and finally completely separates from the fixing seat clamping position 4302 and can be easily taken out by hand, thereby achieving disassembly of the filter element.

[0053] Through the above scheme, the arrangement of the fixed seat clamping position 4302, the filter element clamping strip 4303, the filter element stop baffle 4304 and the clamping guide slope 4305 can realize the rapid disassembly and assembly of the filter element, thereby improving the disassembly and assembly efficiency of the water purifier.

[0054] As an improved specific implementation method, 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; both the large fixing seat ring 4306 and the small fixing seat ring 4308 can be used to connect with the filter element; further, a water stop valve push rod hole 4307 is arranged between the inner wall of the large fixing seat ring 4306 and the outer wall of the small fixing seat ring 4308 and at the same height as the small fixing seat ring 4308; an opening and closing mechanism mounting hole 4318 is axially extended downward directly below the water stop valve push rod hole 4307, and a hole connected to the inner cavity of the large fixing seat ring 4306 is also opened on the side wall of the opening and closing mechanism mounting hole 4318; during assembly, the water stop valve opening and closing mechanism 49 is installed in the opening and closing mechanism mounting hole 4318.

[0055] As an improved specific implementation method, 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 is installed in place, the filter element water outlet push rod 4309 will push open the piston of the water stop valve installed in the water inlet and outlet of the filter element. At this time, the purified water purified by the filter element can flow out of the filter element through the water stop valve. When the filter element 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 is closed, so that the purified water remaining in the filter element will not drip onto the ground, thereby reducing unnecessary trouble; further, a fixed seat water outlet hole 4310 is also arranged on the inner plane of the filter element fixing seat 43 at a position corresponding to the axis of the fixed seat water outlet column hole 4317; the fixed seat water outlet hole 4310 is connected with the fixed seat water outlet column hole 4317, so that the purified water in the filter element can flow out from the filter element fixing seat 43 and then flow into the conveying channel in the integrated waterway plate 41.

[0056] As an improved specific implementation method, two filter element supporting blocks 4311 are arranged on the inner wall of the filter element fixing seat 43 and at a location matching the rotation trajectory of the filter element, 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 clamping column on the filter element when the filter element is rotated for disassembly or installation, thereby making the filter element disassembly and assembly smoother.

[0057] As a specific implementation of the improvement, an installation directional bayonet 4312 is set at the middle position of the fixed seat clamp 4302 away from the filter element stop baffle 4304; when installing the filter element, it only needs to be inserted into the filter element fixing seat 43 and rotated until the alignment clamping point coincides with the installation directional bayonet 4312, and then the filter element is rotated slightly with force, and it will 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. The setting of the installation directional bayonet 4312 allows the user to install the filter element without deliberately aligning it, making the filter element installation more convenient and quick.

[0058] As an improved specific implementation method, a plurality of fixing seat screw holes 4313 are arranged 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 on the fixing seat mounting column 4107 by screws.

[0059] Through the above solution, the arrangement of the fixing seat screw hole 4313 and the fixing seat installation column 4107 can enable the filter element fixing seat 43 to be quickly disassembled and assembled.

[0060] As an improved specific implementation method, a fixed seat water inlet column 4314 is coaxially arranged downwardly below the opening and closing mechanism 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 mechanism mounting hole 4318, and a water stop valve is installed at the fixed seat water inlet column hole 4315 during assembly; when the water stop valve here is opened, water can flow into the filter element, conversely, when the water stop valve here is closed, it will prevent water from flowing into the filter element.

[0061] As an improved specific implementation method, 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 is installed at the fixed seat water outlet column hole 4317; when the water stop valve here is opened, the purified water stored inside the filter element can flow out of the filter element. On the contrary, when the water stop valve here is closed, the purified water inside the filter element will be prevented from flowing out of the filter element. Of course, it should be noted that the specific structure of the water stop valve can be set according to needs.

[0062] As an improved specific implementation method, the flowmeter rotor 45 is installed in the flowmeter rotor mounting groove 4120 inside the first water supply channel 4115 on the integrated water circuit board 41 near the tap water inlet end, and the Hall detector 46 is installed in the Hall detector mounting groove 4113 next to the first water supply channel 4115 port of the integrated water circuit board 41 and corresponding to the position of the flowmeter rotor 45; the flowmeter rotor 45 and the Hall detector 46 form a flowmeter, which can be used to detect the total amount of water flowing through the water purifier, and the Hall detector 46 is electrically connected to the main control circuit board, thereby realizing automatic real-time monitoring.

[0063] As an improved specific implementation, the magnetizer cover 47 is installed above the magnetizer mounting slot 4119 on the integrated water circuit plate 41. When the water quality magnetizer 48 is installed into the magnetizer mounting slot 4119, the water quality magnetizer 48 can be quickly fixed by screws.

[0064] As an improved specific implementation method, the water stop valve opening and closing mechanism 49 can be used to control the opening or closing of the water stop valve installed in the water inlet column hole 4315 of the fixed seat; the lower part of the water stop valve opening and closing mechanism 49 is a flange-shaped opening and closing mechanism 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 mechanism base 491 is against the top plane of the water stop valve, and the lower end of the water stop valve piston rod 493 passes through the center hole of the reset spring 492 and the opening and closing mechanism base 491; after the filter element is installed in place, the water stop valve piston rod 493 is pressed downward, and then the lower end of the water stop valve piston rod 493 pushes the piston of the water stop valve open, so that water can flow out of the integrated water channel structure and pass through the water stop valve into the filter element; on the contrary, when the filter element 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 loses thrust and returns to a closed state, and water cannot flow out of the integrated water channel structure 4, thereby preventing water from dripping onto the outside of the machine flow channel or the ground when the filter element is disassembled and assembled, and can play a good role in preventing dripping.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
