When the casing 100 is a rectangular parallelepiped structure, the waterway plate assembly 110 is vertically disposed and parallel to an inner side surface of one of the side plates.

According to an embodiment of the present invention, the waterway plate assembly 110 includes a waterway plate 120 and a plurality of functional components 140. The water channel plate 120 is internally provided with a plurality of water channels 126 with different functions, and the plurality of water channels 126 are integrally arranged, so that the number of water pipelines is reduced, the connecting structure of the water channel plate assembly 110 is simpler, the volume of the water channel plate assembly 110 and the shell 100 is reduced, the assembly time is reduced, the assembly efficiency is improved, the water pipeline water leakage phenomenon is prevented better, and the stable quality of mass production is ensured.

The water treated by the combination of the different filter element assemblies 170 and the filter element assemblies 170 can be respectively output through the water paths 126 with different functions to meet different water requirements, for example, one can be domestic water, one can be drinking water, one can be tap water, and the other can be wastewater and the like.

In one embodiment, the waterway plate 120 includes a first waterway side plate 122 and a second waterway side plate 124, the first waterway side plate 122 and the second waterway side plate 124 are disposed in parallel, and a waterway 126 is formed therebetween.

In one case, a water tank is disposed on one of two sides of the first waterway side plate 122 and the second waterway side plate 124, which are close to each other, and the first waterway side plate 122 and the second waterway side plate 124 are attached to each other to form a waterway 126.

In another case, the two sides of the first waterway side plate 122 and the second waterway side plate 124, which are close to each other, are provided with water tanks, and the first waterway side plate 122 and the second waterway side plate 124 are jointed and connected to form a waterway 126.

In the case that the tap water inlet 112 is formed on the waterway plate 120, the functional component 140 includes a first total dissolved solid probe 144, and the first total dissolved solid probe 144 is in fluid communication with the tap water inlet 112, so as to monitor the amount of solid particles dissolved in the tap water in real time, and determine whether the tap water reaches the standard.

It can be understood that the first total dissolved solid probe 144 detects poor quality of tap water, and when the total dissolved solids are more, the pressure of the filter element assembly 170 of the water purifying apparatus during filtration is higher, so that the replacement period of the filter element assembly 170 needs to be shortened, and meanwhile, different types of filter element assemblies 170 can be selected according to the total dissolved solids. Similarly, the first total dissolved solids probe 144 detects that the quality of the tap water is better, and when the total dissolved solids are less, the pressure of the filter element assembly 170 of the water purifying device is lower during filtering, so that the replacement period of the filter element assembly 170 can be properly prolonged.

When being formed with drinking water outlet 114 on water route board 120, functional unit 140 still includes the total solid probe 146 that dissolves of second, and the total solid probe 146 that dissolves of second can the total quantity of dissolving the solid in real-time supervision drinking water, can provide whether up to standard information of drinking water for the user, can also remind the user in time to change filter element group spare 170 simultaneously.

The second total dissolved solids probe 146 may monitor the amount of total dissolved solids in the drinking water and may provide the user with information as to whether the drinking water is up to standard. For example, a threshold value is set, and when the amount of impurities in the drinking water exceeds the threshold value, a user is reminded that the drinking water impurities exceed the threshold value and cannot drink the drinking water, and the filter element assembly 170 needs to be replaced as soon as possible.

The first total dissolved solids probe 144 and the second total dissolved solids probe 146 may provide valuable water quality information to the user, facilitating the user's judgment and use.

In some embodiments, the number of filter cartridge assemblies 170 is multiple, the multiple filter cartridge assemblies 170 are in fluid communication via the multiple waterways 126, and the water communication relationship between the filter cartridge assemblies 170 is regulated by the functional component 140.

It will be appreciated that where the functional component 140 includes a proportional valve 142, the proportional valve 142 can adjust the proportion of water from different cartridge components 170, thereby improving the taste of the potable water. The water circuit board 120 can be further provided with an on-off solenoid valve, so that the tap water can be filtered by selecting different combinations of the filter element assemblies 170, and the filtering requirements of different grades and types can be met.

Purifier can be applicable to littleer installation space, can satisfy more installation demands of user, is favorable to improving user's use impression and purifier's market competition.

It should be noted that the filter cartridge assembly 170 and the water pump assembly 150 are located on the same side of the circuit board 120, but on a different side from the functional component 140, ensuring that the functional component 140 is in a location that is easily accessible from the outside.

In some embodiments, the axis of the water pump assembly 150 is parallel to the axis of the filter cartridge assembly 170, and the water pump assembly 150 and the filter cartridge assembly 170 are more compactly installed, thereby making the water purifying apparatus more compact.

According to the water purifying device provided by the embodiment of the invention, the filter element assembly 170 is arranged in the machine cabin 102 and is in fluid communication with the waterway 126, and in order to facilitate the quick connection between the filter element assembly 170 and the waterway plate 120, a component which is convenient to detach and install is arranged between the filter element assembly 170 and the waterway plate 120.

In some embodiments, the waterway plate 120 is provided with a hollow connecting tube 128 at a side close to the filter element assembly 170, and the connecting tube 128 is provided with two opposite ends, one end of the connecting tube 128 is in fluid communication with the waterway 126, and the other end extends to a side far away from the waterway plate 120. Connecting pipe 128 can dismantle with filter element group spare 170 and be connected, and the quantity of connecting pipe 128 is a plurality of, realizes providing running water, discharge drinking water and function such as waste water in to filter element group spare 170 respectively.

According to an embodiment of the present invention, a flexible water stop valve 160 is disposed within the connection tube 128, the flexible water stop valve 160 having an open position and a closed position. In the open position, the connection pipe 128 is in a water guiding state; in the closed position, the connection tube 128 is in a water-blocking state.

It will be appreciated that in the open position the tap water inlet 112 provides tap water to the filter element assembly 170, which after filtration through the filter element assembly 170 removes impurities and dissolved particles from the water to form drinking water and waste water, which respectively flow out along the different connecting tubes 128.

When the filter element assembly 170 is detached, the elastic water stop valve 160 is in a closed position, so that the running water inlet 112 can be prevented from continuously supplying water, drinking water or waste water can be prevented from flowing back along the connecting pipe 128, leakage and sprinkling of liquid are avoided, the pollution to a cupboard or clothes of a user is avoided, and the water supply device is cleaner and more sanitary.

In some embodiments, the elastomeric water stop valve 160 includes a central rod 162, a first seal 164, and an elastomeric member 168.

The central rod 162 has a first end and a second end opposite to each other, the first end is formed with a first blocking portion 166, the position in the connecting pipe 128 close to the waterway 126 is provided with a second blocking portion 130 in a ring shape, the central rod 162 is inserted into the connecting pipe 128, and the second end passes through the second blocking portion 130 and is located on one side of the second blocking portion 130 close to the waterway 126.

A first sealing member 164 is sleeved outside the second end of the central rod 162, the first sealing member 164 may be an elastic sealing member made of a rubber material or a silicone material, and an outer diameter of the first sealing member 164 is larger than an inner diameter of the second blocking portion 130. When the center rod 162 moves in the connection pipe 128, both ends of the center rod 162 are located at both sides of the second stopper 130, and the center rod 162 is restricted by the second stopper 130 and does not separate from the connection pipe 128.

The elastic member 168 is sleeved outside the central rod 162 and connected to the first blocking portion 166 and the second blocking portion 130, under the action of elastic restoring force, the central rod 162 moves towards the direction away from the waterway 126, the first sealing member 164 abuts against the second blocking portion 130, the water blocking effect can be achieved, and at this time, the elastic water stop valve 160 is in a closed position. When a force is applied to the center rod 162 in a direction toward the water passage board 120, the elastic member 168 is compressed, the first sealing member 164 is separated from the second blocking portion 130, a flow passage is formed between the two, and a water guiding effect can be achieved, and the elastic water stop valve 160 is in an open position. When the force condition of the elastic member 168 changes, the elastic water stop valve 160 can be switched between the open position and the closed position.

It will be appreciated that when the filter cartridge assembly 170 is removed from the connecting pipe 128, the supporting force acting on the central rod 162 is removed, the central rod 162 moves away from the waterway plate 120 under the action of the elastic member 168, and the first sealing member 164 abuts against the second blocking portion 130, so as to achieve the water blocking effect. When the filter element assembly 170 is removed, the elastic water stop valve 160 can close the waterway 126, so that leakage of tap water, domestic water, waste water and the like in the waterway plate assembly 110 can be avoided, and cleanness and sanitation in the cabinet can be ensured.

In some embodiments, the outer side of central rod 162 is provided with a reinforcement that may increase the structural strength of central rod 162.

It will be appreciated that the number of central rods 162 may be multiple, with the reinforcement being evenly distributed on the outside of the central rods 162. In some cases, the reinforcing part is four ribbed plates, the four ribbed plates are distributed in a cross shape, and a flow passage is formed between the ribbed plates. The reinforcement not only increases the structural strength of the central rod 162, but also does not affect the flow of the liquid inside the elastic water stop valve 160.

In some embodiments, the second barrier 130 is formed with a diverging sloped surface 132 toward the direction of the water path 126.

It is understood that, in the water guiding state, the first sealing member 164 is separated from the second blocking portion 130, and a flow path is formed therebetween, and the liquid flows in the connection pipe 128. The inclined surface 132 can shorten the flow path of the liquid, reduce the resistance to the flow of the liquid, facilitate the passage of the liquid in the connection pipe 128, and facilitate the improvement of the flux of the filter element assembly 170.

When the elastic member 168 pushes the first sealing member 164 to approach the second blocking portion 130, the area of the first sealing member 164 contacting the inclined surface 132 is large, and the sealing effect is good. Under the action of elastic restoring force, the first sealing element 164 contacts the gradually contracting inclined surface 132, so that a self-locking effect is formed, and the sealing performance of the elastic water stop valve 160 is improved.
