In addition, the filter element mounting seat 20 is not drawn out from the machine cavity along with the filter element 10, namely, the filter element mounting seat 20 is fixedly arranged in the machine cavity, so that when a user changes the filter element 10 by himself, interference (such as damaging a pipeline) to parts such as a pipeline arranged on the filter element mounting seat 20 due to misoperation of the user can be effectively avoided, and the reliability and the service life of the whole machine are improved.

Preferably, referring to fig. 3 and 4, the filter cartridge 10 includes a filter housing 1 and a filter cartridge portion located within the filter housing 1, an inner interface tube 11 extending from an inner end of the filter housing 1, and an outer interface tube portion 12 extending fixedly radially outwardly from an outer end of the filter housing 1; the filter element mounting seat 20 is provided with a filter element slot 23 for linearly inserting the filter element 10, the inner bottom wall of the filter element slot 23 is provided with an inner interface groove, and the filter element mounting seat 20 is provided with an outer interface groove part 22 positioned at the outer periphery of the outer notch of the filter element slot 23; when the filter element 10 is linearly inserted into the filter element slot 23, the inner joint pipe 11 is inserted into the inner joint slot, and the outer joint pipe 12 is inserted into the outer joint slot 22. So set up, when changing filter core 10, the user only needs to directly take out filter core 10 transversely outwards in the filter core slot 23, then in the in-process of filter core 10 cartridge insertion into filter core slot 23 with interior interface pipe 11 and outer interface pipe portion 12 respectively the one-to-one cartridge can in interior interface groove and outer interface groove portion 22, like this, more be convenient for the user change filter core 10 and maneuverability is also stronger. Further, a plurality of external interface pipes extend inwards from the external interface pipe 12, so that a plurality of external interface grooves for respectively butting with the plurality of external interface pipes can be formed on the peripheral edge of the external notch of the filter element slot 23, and the structure of the whole machine can be more compact. Of course, the filter element 10 may have other suitable manners of being inserted into the filter element mounting seat 20, which will not be described herein.

Further, the outer interface groove 22 is located above the outer notch of the filter element slot 23, referring to fig. 4, so that the outer interface groove 22 is located directly above the filter element slot 23 with respect to the outer interface groove 22 being located at other positions, which is not only beneficial for smooth introduction of liquid into the filter element 10, but also effectively avoids the problem of air blocking of the liquid flowing into the filter element 10 due to the presence of air. Furthermore, to facilitate the user's alignment and insertion of the inner interface tube 11 into the inner interface slot, the difference between the inner diameter of the cartridge slot 23 and the outer diameter of the cartridge 10 should preferably be no greater than 1mm.

Preferably, the cartridge mount 20 is fixedly provided with a waterway plate 30, and referring to fig. 4 to 6, the waterway plate 30 includes a waterway plate water inlet, a waterway plate water outlet, and a waterway plate plug-in portion 33, and when the cartridge 10 is inserted into the cartridge slot 23, the outer mouthpiece 12 is abutted against the waterway plate plug-in portion 33. It can be understood that the traditional embedded water purifying and drinking machine is mainly connected with each waterway component by adopting plastic or silica gel water pipes, so that the interior of the machine is provided with the defects of more pipelines, more pipeline joints and the like, thereby improving the water leakage risk of the waterway. Therefore, by arranging the waterway plate 30 in the embedded water purifying and drinking machine, the water leakage risk can be effectively reduced, the whole machine is compact, and the use experience of a user can be improved. Of course, the number of pipelines and pipeline joints is small, namely the complexity of assembly is reduced, and the assembly efficiency of the whole machine can be greatly improved.

Preferably, the filter core 10 is a composite filter core, that is, the filter core part is provided with multiple filter core layers made of different materials, so that the space required by the filter core 10 in the machine cavity can be greatly reduced by compositing multiple filter cores into an integrated filter core, thereby enabling the whole machine to be small and compact, being beneficial to reducing the transportation and storage cost of the whole machine, and of course enabling the whole machine to be smaller and more attractive. In addition, the number of filter elements 10 required to be arranged in the embedded water purifying and drinking machine is reduced, and the number of joints and the risk of water leakage can be effectively reduced.

Further, the cartridge portion includes a reverse osmosis cartridge layer, and referring to fig. 4 and 5, the embedded water purifier further includes a filtered water booster pump 40 disposed upstream of the water inlet of the reverse osmosis cartridge layer. The reverse osmosis filter element layer is a filter element layer mainly composed of RO membranes, and can effectively remove impurities such as heavy metal ions or bacteria. It will be appreciated that the raw water introduced into the filter element 10 is commonly tap water externally connected to the tap water pipe, and the water pressure in the tap water pipe is usually about 0.3MPa nowadays, but the liquid pressure needs to reach about 0.6MPa to be filtered through the reverse osmosis filter element layer, so in order to enable the liquid to be filtered through the reverse osmosis filter element layer, a water filtering booster pump 40 needs to be added to boost the pressure of the liquid (for example, to about 0.6 MPa).

In addition, the cartridge part further includes a primary cartridge layer, referring to fig. 3 and 5, the outer interface pipe part 12 includes a raw water outer interface pipe 121 as a water inlet of the primary cartridge layer, a pure water outer interface pipe 122 connected to a first water outlet of the reverse osmosis cartridge layer, and a waste water outer interface pipe 123 connected to a second water outlet of the reverse osmosis cartridge layer, the inner interface pipe 11 is formed with an inner water outlet pipe communicating with the first water outlet of the primary cartridge layer and an inner water inlet pipe connected to the water inlet of the reverse osmosis cartridge layer, and the filtered water booster pump 40 is provided on a booster pipe connecting the inner water outlet pipe and the inner water inlet pipe.

Specifically, the primary filter element layer is mainly used for removing rust, sediment, foreign odor, residual chlorine and partial organic matters in adsorbed water, and optionally, the primary filter element layer is mainly composed of PAC filter element layer formed by compounding PP cotton and activated carbon. And will strain water booster pump 40 and set up on connecting the pressurized-water pipeline of inscribing outlet pipe and internal access water pipe, can also make liquid reentrant strain water booster pump 40 after the primary filter core layer filters, can avoid impurity such as silt to block up or damage water booster pump 40 effectively, be favorable to improving the operating performance and the life of booster pump. In addition, raw water is filtered through the primary filter element layer and then is led into the reverse osmosis filter element layer and even more filter element layers made of other materials, so that the filter element layer can be prevented from being damaged by impurities such as rust, sediment and the like in liquid, and the service life of the filter element layer and even the whole integrated filter element is prolonged.

Preferably, referring to fig. 3, the outer mouthpiece portion 12 further includes a strained outer mouthpiece 124 as the second outlet of the primary cartridge layer. It can be understood that, because the primary filtered water filtered by the primary filter element layer can meet the requirements of domestic water such as rice washing, vegetable washing, etc. of users, the primary filtered water filtered by the primary filter element layer can be led out to the outside of the whole machine through the coarse filtration water external interface tube 124 so as to be used as domestic water for users, thus the functions of the embedded water purifying and drinking machine can be more various, and the use experience of the users can be improved. Further, the waterway board plug-in portion 33 further includes a straining outer interface groove 334 interfacing with the straining outer interface pipe 124, the waterway board water outlet further includes a straining output port 323, and a straining water pipeline 344 is formed between the straining outer interface groove 334 and the straining output port 323.

In addition, the inner connecting pipe 11 is a concentric pipe, one of the inner connecting water outlet pipe and the inner connecting water pipe is a circular pipe, and the other is an annular pipe and is arranged around the circular pipe, so that the water filtering booster pump 40 can be directly sleeved with the inner connecting water outlet pipe and the inner connecting water pipe which are concentrically arranged only by adopting a single connecting piece, the number of pipelines and pipeline joints required to be arranged in the whole machine can be reduced, the complex degree of assembly is reduced, and the assembly efficiency of the whole machine is improved.

In the preferred embodiment of the present invention, the filter cartridge 10 comprises a filter housing 1 and a filter core located in the filter housing 1, and an inner water outlet pipe, an inner water pipe, a raw water outer interface pipe 121, a pure water outer interface pipe 122, a waste water outer interface pipe 123 and a coarse filtration water outer interface pipe 124 are provided on the filter housing 1, and the filter core part comprises a primary filter core layer, a reverse osmosis filter core layer and a post-carbon filter core layer. The primary filter element layer and the reverse osmosis filter element layer are sequentially arranged from outside to inside and are mutually spaced, and the rear carbon filter element layer is connected with the reverse osmosis filter element layer and is positioned at the downstream of the reverse osmosis filter element layer; the raw water external interface pipe 121 is used as a water inlet of the primary filter element layer, a first water outlet of the primary filter element layer is connected with an internal water outlet pipe, and a second water outlet of the primary filter element layer is communicated with the coarse water filtering external interface pipe 124; the inner water inlet pipe is communicated with the water inlet of the reverse osmosis filter element layer, the first water outlet of the reverse osmosis filter element layer is connected with the water inlet of the rear carbon filter element layer, and the second water outlet is connected with the wastewater outer interface pipe 123; the pure water external interface pipe 122 is used as a water outlet of the rear carbon filter element layer.

Preferably, the primary filter element layer may be a PAC filter element layer mainly composed of PP cotton and activated carbon, for example, the primary filter element layer may include a PP nonwoven fabric winding layer (the precision of the PP nonwoven fabric winding layer may be set to 5 μm) and an activated carbon fiber winding layer sequentially distributed from the outside to the inside in the radial direction, so that not only large particulate matters such as rust and silt in the liquid can be effectively removed, but also heterochromatic, peculiar smell, residual chlorine and partial organic matters in the liquid can be adsorbed, thus, the influence of large particulate matters in the liquid on the reverse osmosis filter element layer and the post carbon filter element layer can be avoided, and the service lives of the reverse osmosis filter element layer and the post carbon filter element layer can be prolonged. In addition, because the primary filter water filtered by the primary filter core layer can meet the requirements of domestic water such as rice washing, vegetable washing, washing and the like of users, the primary filter water filtered by the primary filter core layer can be led to the outside of the whole machine through the coarse filter water external interface pipe 124 to serve as the domestic water for the users, so that the functions of the embedded water purifying and drinking machine are more various, and the use experience of the users is improved.

In addition, the reverse osmosis filter element layer is a filter element layer mainly composed of RO membranes, so that impurities such as heavy metal ions or bacteria can be effectively removed; the rear carbon filter element layer can be an active carbon filter element layer, for example, the rear carbon filter element layer is a filter element layer formed by active carbon rods, so that volatile organic matters and residual chlorine can be removed, necessary mineral substances such as trace calcium, silicic acid and carbonate can be reserved, and the taste can be sweet and soft.

In the preferred embodiment, raw water (such as tap water from the outside) is initially filtered by the primary filter element layer, and then sequentially fed into the reverse osmosis filter element layer and the rear carbon filter element layer for further depth filtration, thereby preparing pure water for direct drinking by a user. It should be specifically noted that the number, types and flowing order of the filter element layers in the integrated composite filter element are not limited thereto, and may be any other suitable arrangement manner, and specific details may depend on the actual process requirements, which are not described herein.

Specifically, the waterway board plug port 33 includes a raw water outer interface groove 331, a pure water outer interface groove 332, and a waste water outer interface groove 333, which are in one-to-one interfacing with the raw water outer interface pipe 121, the pure water outer interface pipe 122, and the waste water outer interface pipe 123; referring to fig. 7 and 8, the waterway plate water inlet includes a raw water input port 31, the waterway plate water outlet includes a pure water output port 321 and a waste water output port 322, a raw water pipeline 341 is formed between the raw water outer interface tank 331 and the raw water input port 31, a pure water pipeline 342 is formed between the pure water outer interface tank 332 and the pure water output port 321, and a waste water pipeline 343 is formed between the waste water outer interface tank 333 and the waste water output port 322. So configured, when the cartridge 10 is inserted linearly inside the cartridge insertion groove 23, the raw water input port 31 of the waterway plate 30 communicates with the raw water external interface groove 331 of the cartridge 10 so that raw water introduced from the outside flows into the cartridge 10 along the raw water line 341; the pure water external interface groove 332 of the filter element 10 is communicated with the pure water output port 321 of the waterway plate 30, so that pure water which is prepared by filtering the filter element layer by layer and can be directly drunk by a user can flow out through the pure water pipeline 342; the waste water outlet port 333 of the cartridge 10 communicates with the waste water outlet port 322 of the waterway plate 30, so that waste water containing impurities such as heavy metal ions or bacteria, which is obtained by treating primary filtered water from the primary cartridge layer through the reverse osmosis cartridge layer, can be discharged from the whole machine through the waste water pipe 343.

Preferably, the water path plate 30 is further formed with a water filtering booster pump flow pipeline 345, and referring to fig. 6 to 8, a water inlet of the water filtering booster pump flow pipeline 345 is connected with an internal water outlet pipe, a water outlet of the water filtering booster pump flow pipeline 345 is connected with a water inlet of the water filtering booster pump 40, and the water path plate 30 further comprises a water inlet electromagnetic valve 35 arranged on the water filtering booster pump flow pipeline 345. Wherein, the water inlet solenoid valve 35 is mainly cut off or connected with the water filtering booster pump flow pipeline 345 by a user, and the water filtering booster pump 40 and the water inlet solenoid valve 35 are generally started and stopped synchronously, namely, when the water inlet solenoid valve 35 cuts off the booster pump flow pipeline 345, the water filtering booster pump 40 stops working at the same time, at the moment, no liquid flows in the water inlet pipe, namely, the water treatment module 200 stops producing pure water; when the water inlet electromagnetic valve 35 is communicated with the booster pump flow pipeline 345, the water filtering booster pump 40 is started at the same time and pumps the liquid into the inlet water pipe, and then the prepared pure water flows out from the pure water outlet 321.

Specifically, the water inlet electromagnetic valve 35 is arranged at the downstream of the primary filter element layer, so that the liquid can be filtered by the primary filter element layer and then enters the water inlet electromagnetic valve 35, the water inlet electromagnetic valve 35 can be prevented from being blocked or damaged by impurities such as sediment and the like, and the service life of the water inlet electromagnetic valve 35 can be prolonged. In addition, the water inlet electromagnetic valve 35 is arranged on the water filtering booster pump overflow pipeline 345, the number of the pipeline and the pipeline connectors can be reduced, the water leakage risk of the whole machine can be effectively reduced, the use experience of a user is improved, the assembly complexity of the whole machine can be greatly reduced, and the assembly efficiency of the whole machine is improved.

In addition, referring to fig. 6 to 8, the waterway plate 30 further includes a waste water solenoid valve 36 disposed on the waste water pipe 343, wherein the waste water solenoid valve 36 disposed on the waste water pipe 343 is mainly used to adjust a waste water ratio to balance an operating pressure of the waterway pipe in the water treatment module 200. Of course, the wastewater solenoid valve 36 is disposed on the wastewater pipeline 343, so that the number of pipelines and pipeline connectors disposed in the water treatment module 200 can be reduced, which is beneficial to reducing the water leakage risk and the complicated assembly of the whole machine.

Preferably, the raw water one-way valve is arranged in the raw water external interface groove 331, and is set to be opened when the external interface pipe 12 is abutted against the waterway board plug-in port 33 and closed when the external interface pipe 12 is separated from the waterway board plug-in port 33, so that the raw water can be ensured not to flow out of the raw water external interface groove 331 through the raw water pipeline 341 when the filter element 10 is replaced by a user, and the use experience of the user is improved.

Specifically, the embedded water purifier includes a water tank 50 connected to a purified water outlet 321 of the water path plate, so that the purified water can be stored in the water tank 50 to meet the requirement of large flux of users. In addition, in order to make the whole structure compact, referring to fig. 4 and 5, the water tank 50, the cartridge mount 20, and the filtered water booster pump 40 are preferably arranged vertically downward in order.

Preferably, referring to fig. 4, a filter element life time key 24 is provided on the outer periphery of the outer notch of the filter element slot 23, so that after the replacement of the filter element 10 is completed, the user can conveniently manually touch the filter element life time key 24 by himself so as to count down the service life of the filter element 10 again. Of course, the timing of the service life of the filter element 10 may be other suitable manners besides key triggering, and is not exemplified herein.

In addition, the pressure of the liquid flowing into or out of the filter element 10 is generally high (e.g., the water pressure of the raw water is about 0.3MPa, the water pressure from the filtered water booster pump 40 is about 0.6MPa, etc.), so that as long as at least one pipe orifice of the water inlet or the water outlet of the filter element 10 is arranged to extend towards the inner end of the filter housing 1, once the pipe orifice extending towards the inner end is circulated with the liquid, the filter element 10 is given an outward acting force along the axial direction of the filter element 10, and at this time, the filter element 10 is more likely to fly out from the filter element slot 23 under the action of the acting force, which can bring an extremely bad use experience to the user. In addition, in a conventional embedded water purifying and drinking machine, the filter element 10 is usually screwed into the filter element mounting seat 20 in a rotating manner to limit and fix the filter element 10, but the operation in the manner is inconvenient, and the filter element 10 is easily separated from the filter element mounting seat 20 during operation due to the fact that a user is not screwed in place, so that the reliability of the whole machine is lower.
