Description

TECHNICAL FIELD

[0001] The present application relates to the field of household appliances, in particular to a modular water purifier. BACKGROUND

[0002] A water purifier is a household appliance that integrates water purification and drinking water functions. It uses multi-stage filtration technology (such as PP cotton, activated carbon, RO reverse osmosis membrane, etc.) to deeply purify tap water, effectively removing harmful substances such as impurities, heavy metals, bacteria, and viruses. It also integrates heating, refrigeration, or normal temperature water supply functions, and can directly provide safe and clean drinking water to meet users' daily drinking, tea brewing, coffee brewing, and other diverse needs, providing convenience and health.

[0003] Traditional water purifiers usually adopt an integrated design, with fixed integration of various functional modules (such as filter cartridges, water tanks, and main machines), leading to complex installation and maintenance, difficult upgrades and expansions, and users' difficulty in flexibly configuring functions according to their needs. The water source is single (usually only supporting municipal tap water), and there is a lack of flexibility in adapting to bottled water or external water purifiers, limiting the use scenarios. SUMMARY

[0004] To improve the problem of flexible configuration of functions and single water source caused by the integrated design of traditional water purifiers, the present application provides a modular water purifier.

[0005] The modular water purifier provided by the present application adopts the following technical solution:

[0006] A modular water purifier includes a main machine and a functional module fixed to one side of the main machine through a connecting mechanism. The functional module can be selectively connected to the main machine and in fluid communication with the water treatment system inside the main machine. The functional module is one or more of a filter cartridge module, a water tank, or a smart seat. The bottom end of the main machine and the functional module are provided with quick connectors, and adjacent modules are in fluid communication with the water pipe through the quick connectors. Different water sources and water supply requirements are adapted by combining different functional modules with the main machine. The connecting mechanism includes a plurality of mounting holes and jacks opened on the connecting side of the main machine, and a clamping block and a plug block fixed to the functional module. The clamping block and the plug block are respectively adapted to the shape of the mounting hole and the jack. A threaded hole is opened at the bottom end of the plug block. When the clamping block and the plug block are inserted into the mounting hole and the jack, respectively, a screw is passed through the bottom end of the main machine and the threaded hole to fix the main machine and the functional module.

[0007] The host is a core component, and the water treatment system is built-in; the functional module (filter core module, water tank or smart seat, etc.) can be selectively connected to the host and in fluid communication with the water treatment system inside the host to adapt to different water sources and water supply requirements; the quick connector cooperates with the water pipe and the adjacent module to realize fluid communication; in the connecting mechanism, the mounting hole on the connecting side of the host and the insertion hole, the clamping block on the functional module and the insertion block are used for preliminary positioning connection, the threaded hole at the bottom end of the insertion block cooperates with the screw passing through the bottom end of the host to realize stable fixation of the host and the functional module.

[0008] Preferably, the host and the filter core module are combined to form a first configuration, and the filter system is arranged in the filter core module.

[0009] By adopting the above technical scheme, the host and the filter core module with the built-in filter system are combined into a first configuration to meet the filtering treatment of the water source to adapt to the corresponding drinking water demand.

[0010] Preferably, the water tank is away from the side of the host, and a second configuration is formed.

[0011] By adopting the above technical scheme, the water tank and the filter core module with the filter system are combined into a second configuration on the side away from the host to realize water storage and filtration, and meet the independent water storage and purified water demand in specific scenarios.

[0012] Preferably, the water tank is connected to one side of the host to form a third configuration.

[0013] By adopting the above technical scheme, the water tank is connected to one side of the host to form a third configuration, which provides water storage for the host of the water purifier and guarantees continuous and stable water supply.

[0014] Preferably, the top of the host is provided with a smart seat for receiving bottled water to form a fourth configuration.

[0015] By adopting the above technical scheme, the smart seat is arranged at the top of the host to form a fourth configuration, which facilitates the reception of bottled water and provides a convenient bottled water access mode for the water purifier to obtain water sources.

[0016] Preferably, the host and the functional module are connected through a fixing mechanism, the fixing mechanism includes a fixing seat fixed to the connecting side of the host and a connecting block inserted around the fixing seat, and the side away from the fixing seat of the plurality of connecting blocks is fixed to the connecting side of the functional module.

[0017] By adopting the above technical scheme, the fixing seat and the connecting block constitute the fixing mechanism to realize the connection of the host and the functional module and stably connect the host and the functional module.

[0018] Preferably, the fixed base is symmetrically slidably provided with slide rods inside, and sleeve blocks are fixed at both ends on opposite sides of the two slide rods. A spring block is slidably provided inside the sleeve block. A second spring is fixed at one end of the spring block inside the sleeve block. The two ends of the second spring are fixed to the inside of the sleeve block and the end of the spring block near the sleeve block, respectively. The spring block is movably inserted into the connecting block.

[0019] By adopting the above technical solution, the slide rod with symmetrical sliding inside the fixed seat has sleeve blocks at both ends. The sleeve blocks are equipped with spring blocks with springs. The spring blocks can be inserted into the connecting block by means of springs, so as to realize the flexible connection and stable fixation between the fixed seat and the connecting block.

[0020] Preferably, a rotating shaft is symmetrically fixed in the middle of the inner wall of the fixed base, and a spur gear one and a spur gear two are rotatably sleeved on the rotating shaft. A toothed plate that meshes with the spur gear one is fixed in the middle of the slide rod.

[0021] By adopting the above technical solution, spur gear one and spur gear two are sleeved on the symmetrical rotating shaft in the middle of the inner wall of the fixed seat. The toothed plate in the middle of the slide rod meshes with spur gear one. The rotation of spur gear one can drive the toothed plate and slide rod to move, thereby realizing the flexible driving of the slide rod.

[0022] Preferably, the inner wall of the fixed base between the two spur gears is slidably provided with a pressing plate whose lower end meshes with the spur gears. The inner wall of the fixed base is fixedly provided with a fixing block directly below the pressing plate. The top end of the fixing block is provided with a plurality of springs, and the two ends of the springs are respectively fixed to the bottom end of the pressing plate and the top end of the fixing block.

[0023] By adopting the above technical solution, a pressing plate is slidably arranged between two spur gears inside the fixed base, and its lower end meshes with the spur gear. The lower fixed block supports the pressing plate through a spring. The pressing plate moves up and down elastically through the spring and drives the spur gear to rotate, thereby realizing the linkage and operation control of related components.

[0024] Preferably, the inner wall of the fixed base is fixedly provided with a second fixing block in the middle of the pressing plate, the middle part of the pressing plate slides through the interior of the second fixing block, and the upper end of the pressing plate slides through the inner top surface of the fixed base.

[0025] By adopting the above technical solution, the second fixing block is located in the middle of the pressing plate inside the fixing seat, which guides and limits its sliding and ensures the stable movement of the pressing plate. At the same time, the upper end of the pressing plate penetrates the inner top surface of the fixing seat, which facilitates external operation to press and drive the internal related structures to move together.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By allowing users to select module combinations according to their needs (such as main unit + filter module, main unit + filter module + water tank, or main unit + water tank and main unit), quick connectors can quickly connect the main unit and the water system of the functional modules, enabling efficient connection of the water treatment processes of different modules. Through the matching and fixing of the clips and mounting holes, the plugs and sockets, and the screw tightening, the main unit and functional modules are firmly connected. This solves the problem of fixed integration and difficult upgrades and expansions of traditional water purifier functional modules, and realizes users' needs for flexible configuration of functions (such as adapting to municipal tap water, bottled water or external water purifiers) and scenario expansion (such as small-capacity direct drinking or large-capacity water storage).

[0028] 2. By pressing the button, the pressing plate moves down along the groove of the second fixing block, causing the rack of the pressing plate to mesh with the second spur gear, which in turn drives the first spur gear to rotate. This drives the two sliding rods to slide in opposite directions on the inner wall of the fixing seat, thereby causing the spring block to exit from the rectangular hole of the connecting block, achieving rapid mechanical separation of the filter module from the main unit. During installation, the connecting block is inserted into the through hole, and the spring block is automatically locked into the rectangular hole by the action of the second spring, solving the problems of complex disassembly and assembly and time-consuming maintenance of traditional water purifier modules.

The main unit 1 is connected to the filter module 2 or the water tank 11 through the fixing mechanism 13. The fixing mechanism 13 includes a fixing seat 1301, the shape of which is (e.g., Figure 16As shown, through holes 1317 are symmetrically provided on both sides of the fixing base 1301. A rectangular groove 1318 is provided inside the through hole 1317. The rectangular groove 1318 communicates with the through hole 1317 and the interior of the fixing base 1301. The size of the through hole 1317 is larger than the size of the rectangular groove 1318. A rectangular groove 1319 is provided in the middle of the upper end of the fixing base 1301. The rectangular groove 1319 communicates with the interior of the fixing base 1301. Slide rods 1302 are symmetrically slidably arranged inside the fixing base 1301. Sleeve blocks 1309 are fixed at both ends of opposite sides of the two slide rods 1302. A sliding groove 1314 is provided inside the sleeve block 1309. A spring block 1310 is slidably arranged inside the sliding groove 1314. The shape of the spring block 1310 is adapted to the shape of the sliding groove 1314, so that the spring block 1310 slides inside the sliding groove 1314 without disengaging from the interior of the sliding groove 1314.

[0066] A second spring 1313 is installed inside the slide groove 1314 (the formula for calculating the elastic force of the second spring 1313 is F=kx, where F represents the elastic force of the second spring 1313, k represents the spring constant, and x represents the compression of the second spring 1313). Both ends of the second spring 1313 are fixed to the inner wall of the slide groove 1314 and one end of the spring block 1310 located inside the slide groove 1314, respectively. The spring block 1310 is wedge-shaped and slidably disposed in the rectangular hole 1312 of the connecting block 1311, with the wedge-shaped end of the spring block 1310 extending out of the connecting block 1311. On the outer side of 311, a rectangular hole 1312 is provided on the side of the connecting block 1311 near the spring block 1310. The shape of the rectangular hole 1312 is adapted to the shape of the spring block 1310, and the spring block 1310 is inserted into the rectangular hole 1312. The shape of the connecting block 1311 is adapted to the shape of the through hole 1317, and the connecting block 1311 is engaged in the through hole 1317. The side of the connecting block 1311 away from the fixing seat 1301 is fixed to the side of the filter module 2 facing the fixing seat 1301. A toothed plate 1315 is fixed in the middle of the slide rod 1302. The shape of the toothed plate 1315 is as follows (e.g., Figure 14 As shown), the toothed plate 1315 has a meshing groove at its lower end on the side facing the fixed seat 1301.

[0067] A rotating shaft 1304 is symmetrically fixed in the middle of the inner wall of the fixed base 1301. A spur gear 1303 and a spur gear 1305 are rotatably sleeved on the rotating shaft 1304. The spur gear 1305 is rotatably sleeved at the end of the rotating shaft 1304 near the inner wall of the fixed base 1301, and the spur gear 1303 is rotatably sleeved at the end of the rotating shaft 1304 away from the inner wall of the fixed base 1301. The diameter of the spur gear 1303 is the same as the diameter of the spur gear 1305. The teeth on the surface of the spur gear 1303 interact with the toothed plate 1315. The meshing grooves engage. A rectangular groove 1316 is provided on the side of the slide rod 1302 near the fixed base 1301. The length of the rectangular groove 1316 is greater than the diameter of the first spur gear 1303 and the second spur gear 1305. This is to ensure that the rotation of the first spur gear 1303 is not affected when the first spur gear 1303 drives the tooth plate 1315 to move. The tooth plate 1315 is located above the rectangular groove 1316. The thickness of the meshing groove provided on the tooth plate 1315 is the same as the thickness of the first spur gear 1303, so as not to affect the rotation of the second spur gear 1305.

[0068] A pressing plate 1306 is provided on the side of the spur gear 1305 away from the slide bar 1302. A rack is provided at the lower end of the pressing plate 1306, and the rack of the pressing plate 1306 meshes with the teeth on the surface of the spur gear 1305. The thickness of the pressing plate 1306 is the same as the thickness of the spur gear 1305. A fixing block 1307 is fixed at the lower end of the inner wall of the fixing base 1301. The fixing block 1307 is located directly below the pressing plate 1306. Multiple springs 1308 are provided at the top of the fixing block 1307 (the formula for calculating the elastic force of springs 1308 is F=kx, where F represents the elastic force of springs 1308, k represents the constant of springs 1308, and x represents the elastic force of springs 1308). The spring 1308 is compressed. The two ends of the spring 1308 are fixed to the bottom end of the pressing plate 1306 and the top end of the fixing block 1307, respectively. The inner wall of the fixing base 1301 is fixed to the middle of the pressing plate 1306 and a fixing block 1320 is fixed thereon. The fixing block 1320 has a groove inside. The shape and size of the groove are adapted to the cross-sectional shape and size of the pressing plate 1306. The middle part of the pressing plate 1306 slides through the groove of the fixing block 1320. A button is provided at the top of the pressing plate 1306. The shape and size of the button are adapted to the shape and size of the rectangular groove 1319. The button slides through the upper end of the pressing plate 1306 in the rectangular groove 1319.

[0069] The user gently pushes the connecting block 1311 of the filter module 2 into the through hole 1317 of the mounting base 1301 of the main unit 1. The rectangular hole 1312 of the connecting block 1311 contacts the spring block 1310 inside the mounting base 1301. The wedge-shaped end of the spring block 1310 is compressed and retracts into the slide groove 1314. At this time, the second spring 1313 is in a compressed state. When the connecting block 1311 is fully inserted into the through hole 1317, the first spring 1308 rebounds, causing the wedge-shaped end of the spring block 1310 to extend out of the slide groove 1314 and lock into the rectangular hole 1312 of the connecting block 1311, thus completing the mechanical locking. Finally, the water pipe is connected through the quick connector 4 at the bottom of the main unit 1 and the bottom of the filter module 2 to complete the water circuit connection.

[0070] When the user needs to disassemble the filter module 2, press the button, and the pressing plate 1306 moves down. Through the second spur gear 1305 and the first spur gear 1303, the two sliding rods 1302 slide in opposite directions on the inner wall of the fixed seat 1301, causing the wedge-shaped end of the spring block 1310 to exit from the rectangular hole 1312 of the connecting block 1311. The user can then pull the connecting block 1311 out of the through hole 1317 to complete the mechanical separation of the filter module 2 from the main unit 1. Afterwards, disconnect the water pipe connected to the quick connector 4 at the bottom of the main unit 1 and the bottom of the filter module 2 to completely complete the disassembly.

[0071] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
