Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. Furthermore, various embodiments or examples and features of different embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.
It should be noted that the embodiment of the present invention is only described by taking the filtration of water as an example, and it is obvious that the application of the filter assembly is not limited to the filtration of water, and can also be used for the filtration of other liquids.
Referring to fig. 1 to 4, according to an embodiment of the present invention, the water tank assembly includes a raw water tank 105 and a concentrated water tank 102, the concentrated water tank 102 includes a first tank 206 and a water inlet pipe 201 communicated with the first tank 206, a first end of the water inlet pipe 201 is located inside the first tank 206, a water outlet 301 is formed at the first end of the water inlet pipe 201, and a height of the water outlet 301 is not lower than a highest water level of the raw water tank 105.
The first tank 206 of the concentrate tank 102 may be understood as a body of the concentrate tank 102, i.e., a remaining portion except for various accessories. Referring to fig. 5, it can be understood that the portion of the thickening tank 102 excluding the inlet pipe 201 is referred to as a first tank 206 including a side wall and a bottom plate.
According to the water tank assembly, the height of the water outlet 301 is not lower than the highest water level of the raw water tank 105, so that raw water in the raw water tank 105 can be prevented from flowing into the concentrated water tank 102 under the action of water level difference, and waste of water resources is prevented. It should be noted that, since the first end of the inlet pipe 201 where the water outlet 301 is located inside the concentrated water tank 102, the concentrated water in the concentrated water tank 102 can be prevented from flowing back to the raw water tank 105.
When the height of the water outlet 301 is higher than the highest water level of the raw water tank 105, raw water can be better prevented from being stolen into the concentrated water tank 102.
According to the embodiment of the invention, the concentrated water tank 102 is arranged in the raw water tank 105, and the bottom surface of the raw water tank 105 is provided with a water inlet interface 202 communicated with the water inlet pipe 201. Under this kind of circumstances, when guaranteeing former useless separation, can save the occupation space of water tank set spare.
Wherein the concentrate tank 102 is embedded in the raw water tank 105 and is detachably connected to the raw water tank 105. In this case, the concentrated water tank 102 and the raw water tank 105 are more conveniently and sufficiently cleaned. Specifically, to clean the raw water tank 105, the concentrate tank 102 may be detached from the raw water tank 105. Similarly, to facilitate cleaning of the concentrate tank 102, the concentrate tank 102 may be removed from the raw water tank 105.
The concentrated water tank 102 and the raw water tank 105 may be fixed by a buckle 601, or may be fixed by any other detachable manner.
Referring to fig. 5 and 6, a snap 601 is formed on a sidewall of the first housing 206 of the concentrated water tank 102, and a locking groove for engaging with the snap 601 is formed on the raw water tank 105. Furthermore, when the first tank 206 enters the raw water tank 105, the buckle 601 enters the slot and is fastened under the action of gravity. Even if the concentrated water tank 102 is subjected to the buoyancy of the raw water tank 105, the engagement between the clip 601 and the clip groove can prevent the concentrated water tank 102 from being separated from the raw water tank 105.
The buckle 601 can be set to have a certain elastic structure, so that elastic fit between the buckle 601 and the clamping groove is ensured.
It should be understood that the connection between the raw water tank 105 and the concentrated water tank 102 is not limited by the examples.
As can be seen from fig. 2 and 3, the portion of the inlet pipe 201 located in the first tank 206 is higher than the bottom plate of the first tank 206 by a large distance, so that the backflow of the concentrate from the outlet 301 can be more reliably prevented.
Also, referring to fig. 2 and 3, the inlet pipe 201 has a slim structure. Of course, the structure in the drawings does not limit the water inlet pipe 201, and the water inlet pipe 201 only needs to meet the water inlet requirement of the concentrated water.
According to an embodiment of the present invention, the first end port of the inlet pipe 201 is closed by an end plate, and the outlet 301 extends from the side wall of the inlet pipe 201 to said end plate. Under the condition, the water outlet 301 can simultaneously discharge water through the side wall and the end plate, so that the smoothness of water flow is ensured. Also, since the first end port of the inlet pipe 201 is closed by the end plate, the concentrate water does not flow from the inlet pipe 201 into the concentrate tank 102 in a vertical direction.
Referring to fig. 1 to 3, the second end of the water inlet pipe 201 is located outside the first box 206, and thus the second end of the water inlet pipe 201 can be connected to the water inlet port 202. Wherein, in order to prevent the concentrated water from leaking into the raw water tank 105 through the water inlet port 202, the water inlet pipe 201 is connected with the water inlet port 202 in a sealing manner.
According to an embodiment of the present invention, an annular groove 602 is formed on an outer surface of the second end of the water inlet pipe 201, the first sealing ring 108 is installed in the annular groove 602, the first sealing ring 108 is in interference fit with an inner surface of the water inlet port 202, and thus the first sealing ring 108 ensures a sealed connection between the water inlet pipe 201 and the water inlet port 202.
When the inlet pipe 201 and the water inlet interface 202 adopt a symmetrical structure, the outer surface of the second end of the inlet pipe 201 along the direction close to the water inlet interface 202 inclines towards the direction far away from the central line of the inlet pipe 201. Correspondingly, the inner surface of water inlet port 202 is inclined in a direction towards the centre line of water inlet pipe 201 in a direction towards water inlet pipe 201. Under the condition, a certain clamping locking effect is achieved between the water inlet pipe 201 and the water inlet interface 202, and the sealing effect between the water inlet pipe 201 and the water inlet interface 202 can be fully guaranteed due to the fact that the elastic first sealing ring 108 is arranged on the outer surface of the water inlet pipe 201.
In addition, referring to fig. 1 to 4, the water tank assembly further includes a top cover 101, wherein the top cover 101 is detachably mounted at an opening of the raw water tank 105, so as to facilitate the filling of water into the raw water tank 105 and the discharging of concentrated water in the concentrated water tank 102.
Further, as can be seen from fig. 2 and 3, a first stopper is formed on an inner surface of the water inlet 202, and a first valve assembly for opening and closing the water inlet 202 is further installed in the water inlet 202. Wherein the first valve assembly comprises a first plug 203, a first mandrel 204 and a first resilient member 205. The first plug 203 is located inside the first stopper; the first end of the first mandrel 204 is connected with the first plug 203 in a pluggable manner, the second end of the first mandrel 204 is provided with a second stopping portion, and the second stopping portion is positioned at the outer side of the first stopping portion; the first elastic element 205 is located between the first stop portion and the second stop portion, and the first elastic element 205 abuts against the second stop portion, so that the first plug 203 fits the first stop portion.
Both the "inside of the first stopper" and the "outside of the first stopper" are relative to the raw water tank 105. In fig. 2 and 3, the upper side of the first stopping portion is closer to the inside of the raw water tank 105, corresponding to the inner side of the first stopping portion; the lower side of the first blocking portion is closer to the outside of the raw water tank 105 and corresponds to the outer side of the first blocking portion.
When the water tank assembly is mounted on a corresponding water purifying device, the first mandrel 204 is jacked up, the first elastic piece 205 is compressed at the moment, and the first mandrel 204 drives the first plug 203 to be separated from the end face of the first stopping part, so that the communication between the concentrated water tank 102 and a water channel of the water purifying device is realized; when the water pump 701 is operated, a positive pressure is generated at a side of the water pump 701 close to the concentrate tank 102, so that the concentrate flows out of the filter cartridge 702 and then enters the concentrate tank 102 through the first valve assembly.
The first plug 203 may, but need not, be a silicone plug with good sealing effect. The first elastic member 205 may, but need not, employ a readily available spring. A circular hole may be formed in the silicone plug, and the first end of the first mandrel 204 is inserted into the circular hole in the silicone plug after passing through the spring.
Wherein the end surface of the first stopping portion is required to form a sealing fit with the first plug 203, so that the first stopping portion is continuous along the inner surface of the water inlet port 202. The second stopping portion is used for limiting the first elastic member 205, and the first elastic member 205 is located between the first stopping portion and the second stopping portion, so there is no special requirement for the shape of the second stopping portion.
Further, the raw water tank 105 includes a second tank body and a drain pipe, a drain port is formed on the second tank body, the drain pipe is communicated with the drain port, and the filter assembly 103 is installed at the drain pipe.
Wherein, when water pump 701 sets up before filter core 702, set up filter assembly 103 through the drain pipe department at former water tank 105 for raw water filters through filter assembly 103 earlier before getting into water pump 701, can avoid in the middle of the foreign matter that carries in the raw water gets into water pump 701, prevents that water pump 701 from becoming invalid, guarantees water purification unit's life.
The filter assembly 103 may take any of the structural forms disclosed in the prior art and which meet the installation requirements.
According to an embodiment of the present invention, the filter assembly 103 includes a cylindrical screen 1032 and a screen cover 1031, the cylindrical screen 1032 being mounted to a first end of the drain pipe and extending along a length direction of the drain pipe; the filter screen cover 1031 is sleeved outside the tubular filter screen 1032, a liquid inlet is formed between the edge of the filter screen cover 1031 and the drain pipe, a liquid outlet is formed at the second end of the drain pipe, and the liquid level of the liquid outlet is lower than that of the liquid inlet so as to form a siphon channel 207 passing through the tubular filter screen 1032 between the liquid inlet and the liquid outlet.
Referring to fig. 2, the siphon channel 207 is indicated by a curve, wherein a starting point of the curve corresponds to an inlet of the siphon channel 207, an end point of the curve corresponds to an outlet of the siphon channel 207, and a direction of an arrow on the curve indicates a flowing direction of the liquid in the siphon channel 207. It should be noted that, in the position shown in the drawing of fig. 2, the screen cover 1031 and the drain pipe are clamped, but a gap exists between the screen cover 1031 and the drain pipe along the periphery of the drain pipe, and further siphon passages are formed between the screen cover 1031 and the drain pipe, between the screen cover 1031 and the cylindrical filter net 1032, and inside the cylindrical filter net 1032.
In fig. 2, it can be approximately considered that a U-shaped channel is formed between a curve located on the left side of the cylindrical screen 1032 and a curve located on the right side of the cylindrical screen 1032, and an end of the U-shaped channel having a high opening is a starting point of the left-side curve, and an end of the U-shaped channel having a low opening is an end point of the right-side curve. Of course, in fig. 2, since the cylindrical screen 1032 has many filtering holes, it can be seen that a U-shaped channel is formed at each filtering hole, and only one of the U-shaped channels is shown in the graph of fig. 2.
Referring to fig. 1 to 3, the edge of the filter cover 1031 refers to the area of the filter cover 1031 near the bottom.
After installing this filter assembly 103 in the drain pipe, can form siphon passageway 207 between filter screen lid 1031, tube-shape filter screen 1032 and drain pipe, and then liquid flows to tube-shape filter screen 1032 from the inlet under the siphonic action to discharge from the liquid outlet, liquid circulation in-process under the siphonic action with tube-shape filter screen 1032 different positions fully contact, and then guarantee tube-shape filter screen 1032's filter effect. The filter assembly 103, since it includes the cylindrical screen 1032 extending along the length of the drain pipe, obviously the cylindrical screen 1032 has a larger area and a better filtering effect than the conventional screen disposed in the pipe. In addition, since the tubular strainer 1032 is disposed at an end of the drain pipe, the tubular strainer 1032 can be cleaned only by removing the strainer cover 1031, so that the cleaning is convenient and the blockage of the tubular strainer 1032 can be avoided. And through set up this kind of filtering component 103 at the drain pipe, can prevent that impurities such as iron rust, suspended solid, colloidal substance in former aquatic from directly flowing from water purification unit, avoid causing harm to the health.
It is worth mentioning that the filter screen cover 1031 sleeved outside the cylindrical filter screen 1032 also has a certain blocking effect on the impurities with larger volume.
The tubular screen 1032 extends in the longitudinal direction of the drain pipe, and the height direction of the tubular screen 1032 is the same as the longitudinal direction of the drain pipe. When the cross section of the drain pipe is circular, the length direction of the drain pipe is also the axial direction of the drain pipe; when the cross section of the drain pipe is square, the length direction of the drain pipe is also the central axis direction of the drain pipe. The shape and size of the cross section of the drain pipe can be different corresponding to different places.
The cylindrical screen 1032 may have an integral structure, or a plurality of screens may be connected by another member. In addition, the cross section of the cylindrical screen 1032 may be circular, square, triangular, irregular, etc.
The filter assembly 103 may also include a bracket 1033, the bracket 1033 being used to secure the tubular screen 1032. For example, the support 1033 includes a top plate, a bottom opening frame, and a support beam, both ends of the support beam are respectively connected to the top plate and the bottom opening frame, and both ends of the cylindrical screen 1032 along the height direction thereof are respectively fixed to the top plate and the bottom opening frame. The tubular screen 1032 can be connected to the first end of the drain pipe through the bottom opening frame. By providing such a holder 1033, the structural strength of the cylindrical screen 1032 can be ensured, and the cylindrical screen 1032 is prevented from being deformed after a certain period of use. Wherein, the quantity of supporting beam is many to evenly set up along tube-shape filter screen 1032's peripheral direction, and then through the setting of many supporting beams, can guarantee the homogeneity of tube-shape filter screen 1032 atress ability.
Wherein the top and bottom aperture frames have a shape corresponding to the cross-sectional shape of the tubular screen 1032.
The cylindrical filter screen 1032 and the bracket 1033 can be prepared by an in-mold injection molding process, so that the cylindrical filter screen 1032 is reliably connected with the top plate and the bottom opening frame, and water can only flow through the cylindrical filter screen 1032.
An annular mounting groove is formed in the outer surface of the bottom port frame, and a second seal ring 1034 is fixed to the annular mounting groove. Further, the bottom port frame extends at least partially into the drain pipe and the second gasket 1034 is in interference fit with the inner surface of the first end of the drain pipe, thereby ensuring a relative fixation between the second gasket 1034 and the first end of the drain pipe.
Of course, the bottom port frame and the drain pipe may be connected by other means than the fixed connection via the second sealing ring 1034. For example, the bottom port frame is connected with the first end of the drain pipe through a clamp; or the bottom opening frame is connected with the first end of the drain pipe through a pipe joint; still alternatively, the bottom port frame and the first end of the drain pipe are threadably connected, and so on. Even, the bottom port frame and the first end of the drain pipe can be welded, bonded and the like.
The cylindrical filter net 1032 and the drain pipe can be directly detachably connected, and certainly can be indirectly detachably connected through the bracket 1033.
The tubular filter net 1032 is detachably connected with the drain pipe, so that the tubular filter net 1032 can be periodically detached and cleaned, and the tubular filter net 1032 can be conveniently recycled. Of course, replacement of the tubular screen 1032 may be performed by detaching and attaching the screen.
Further, be connected through the detachable mode between drain pipe lateral wall and the filter screen lid 1031, and then the dismouting of filter assembly 103 that can be convenient for makes things convenient for filter assembly 103's change and washing etc..
For example, the outer side wall of the drain pipe can be clamped to the filter cover 1031. Accordingly, the drain pipe and the screen cover 1031 are securely attached to each other, and the screen cover 1031 is prevented from separating from the tubular screen 1032 by buoyancy. Of course, besides the connection by the clamping, the outer side wall of the drain pipe can be detachably connected with the filter cover 1031, and it is only necessary to ensure that the liquid can enter the siphon channel 207 while ensuring the connection between the outer side wall of the drain pipe and the filter cover 1031, so that a channel for liquid circulation must be provided between the drain pipe and the filter cover 1031.
Further, the drain pipe lateral wall joint in the joint section of filter screen lid 1031, does not influence the feed liquor area of inlet from this.
