The water quality purifying assembly 100 according to the embodiment of the present application is proposed as described below with reference to fig. 1 to 7, the water quality purifying assembly 100 having a disassembled state and an assembled state, comprising: a water stopping component 1 and a bypass seat 2. The bypass seat 2 is configured to be detachably provided on the water stopping member 1.

A water stop member 1 according to an embodiment of the present application is described below with reference to fig. 1 to 4, the water stop member 1 being for use with a filter cartridge, comprising: a cartridge housing 10 and a water stop mechanism 11. The cartridge housing 10 is of hollow structure, and a water-stop chamber 101 is constructed in the cartridge housing 10. The water stop mechanism 11 is movably provided in the water stop chamber 101, a first passage 110 is configured in the water stop chamber 101, the first passage 110 is located between the cartridge housing 10 and the water stop mechanism 11, and a second passage 111 is configured in the water stop mechanism 11. In order to avoid the problem of water outflow in the filter element during the extraction and replacement. A check valve 115 for switching according to a pressure difference is provided in the second passage 111. The check valve 115 is used not only to limit the water flow direction but also to switch on and off according to the pressure difference.

As shown in fig. 6 to 8, the bypass seat 2 is provided with a water inlet 213 and a water outlet 214, and the bypass seat 2 is detachably connected to the cartridge housing 10. The water inlet 213 is used for connecting a tap water pipe, and the water outlet 214 is externally connected with other mechanisms, such as a valve body, a distributor, a refrigerating ice maker or a freezing ice maker, etc.

As shown in fig. 1 to 3, when the filter element is found to be required to be pulled out and replaced, the water stop member 1 can be detached from the bypass seat 2, and the filter element housing 10 is separated from the bypass seat 2; the water stop mechanism 11 moves to the blocking position of the water stop chamber 101. As shown in fig. 1, the water stopping mechanism 11 moves upward relative to the water stopping cavity 101, at this time, the water stopping cavity 101 blocks the first channel 110, at this time, the check valve 115 determines that the pressure difference between two ends is smaller, and then the second channel 111 is controlled to be blocked, so as to realize the water stopping function of the water stopping component 1. As shown in fig. 7, in order to ensure the normal operation of the waterway system, the bypass seat 2 communicates with the water inlet 213 and the water outlet 214 during this process; therefore, water flowing in from the tap water pipe enters the bypass seat 2 through the water inlet 213, and enters other mechanisms through the water outlet 214 of the bypass seat 2, so that the water path is ensured to be smooth when the filter element is replaced.

When the water stop member 1 is found to be mounted on the bypass receptacle 2, the water purification assembly 100 is in an assembled state at this time, and the water stop mechanism 11 is moved to the communication position of the water stop chamber 101. As shown in fig. 2, the water stop mechanism 11 moves downward relative to the water stop cavity 101, at this time, the water stop cavity 101 is opened to the first channel 110, at this time, the check valve determines that the pressure difference between the two ends is large, and then the second channel 111 is controlled to be opened to realize the conduction function of the water stop component 1. As shown in fig. 8, the bypass receptacle 2 communicates with the water inlet 213 and the water outlet 214 through the first passage 110 and the second passage 111 at this time. From this, the water that the running water pipe flowed in gets into bypass seat 2 through water inlet 213, then water is filtered by the filter core through stagnant water mechanism 11, and finally gets into other mechanisms by bypass seat 2's outlet 214, purifies water through water purification subassembly 100, guarantees that whole waterway system normally works.

According to the water quality purifying assembly provided by the invention, the first channel and the second channel are constructed in the water stopping mechanism, and the one-way valve is arranged in the second channel, so that the water stopping mechanism moves to the blocking position of the water stopping cavity under the condition that the water quality purifying assembly is in a disassembled state, the first channel is blocked by the water stopping cavity, the second channel is blocked by judging the pressure difference through the one-way valve, the problem that water in the filter element flows out during the process of pulling out and replacing the filter element is avoided, and the core replacing experience of a user is improved. Meanwhile, the bypass seat is communicated with the water inlet and the water outlet to ensure the smoothness of the waterway when the filter element is replaced. And under the condition that the water quality purifying component is in an assembled state, the water stopping mechanism moves to the communicating position of the water stopping cavity, the first channel is opened by utilizing the water stopping cavity, the second channel is communicated by utilizing the judgment of the one-way valve on the pressure difference, and the normal operation of the filter element is ensured. Meanwhile, the bypass seat is communicated with the water inlet and the water outlet through the first channel and the second channel to purify water, so that the whole waterway system is ensured to work. The problem of poor user experience caused by the fact that the plug is independently configured to keep the use of the waterway is avoided.

In one example, as shown in fig. 1 to 4, the water stop member 1 further includes: a first seal ring 12. The first seal ring 12 may be a rubber seal ring. The first sealing ring 12 is sleeved on the water stopping mechanism 11, and the first sealing ring 12 is positioned between the water stopping mechanism 11 and the filter element shell 10.

In the present embodiment, the water stop mechanism 11 is movable up and down with respect to the water stop chamber 101, and the first seal ring 12 is provided on the water stop mechanism 11. Thus, the first seal ring 12 can move up and down with respect to the water stop chamber 101.

When the filter element is found to be required to be pulled out and replaced, the water stop component 1 can be detached from the bypass seat 2 as shown in fig. 1, and the water purification assembly 100 is in a detached state. The water stop mechanism 11 moves upward relative to the water stop chamber 101, and the water stop mechanism 11 moves to the blocking position of the water stop chamber 101. The first sealing ring 12 moves to a position in the water stopping cavity 101, the water stopping cavity 101 is matched with the first sealing ring 12 to block the first channel 110, at the moment, the check valve 115 judges that the pressure difference between two ends is smaller, and then the second channel 111 is controlled to be blocked, so that the water stopping function of the water stopping component 1 is realized.

As shown in fig. 2, when the water purification assembly 100 is in the assembled state, the water stop mechanism 11 is moved to the communication position of the water stop chamber 101. The first seal ring 12 opens the first passage 110. At this time, if the check valve judges that the pressure difference between the two ends is large, the second passage 111 is controlled to be opened, so that the conduction function of the water stop member 1 is realized.

As shown in fig. 3, a third sealing ring 14 may be further disposed on the water stopping mechanism 11, a plurality of third sealing rings 14 may be disposed, each of the third sealing rings 14 is a rubber sealing ring, each of the third sealing rings 14 is sleeved on the water stopping mechanism 11, the third sealing ring 14 is also located between the water stopping mechanism 11 and the filter core housing 10, and the third sealing ring 14 is generally disposed at an open edge of the water stopping cavity 101 to ensure that the water stopping component is in a state switching process.

Specifically, as shown in fig. 1 to 4, a first protrusion 1010 is provided in the water stop chamber 101. The first protrusion 1010 is an annular protrusion.

In the case where the water quality purifying assembly 100 is in the disassembled state, the water stopping mechanism 11 moves upward with respect to the water stopping chamber 101, and the water stopping mechanism 11 moves to the blocking position of the water stopping chamber 101. The first seal ring 12 abuts against the first protrusion 1010, and the first seal ring 12 forms a first seal surface at the first protrusion 1010. At this time, the first sealing surface serves to seal and block the first passage 110. At this time, when the check valve 115 determines that the differential pressure between both ends is small, the second passage 111 is controlled to be blocked, and the water stop function of the water stop member 1 is realized.

In the state where the water purification assembly 100 is in the assembled state, the water stop mechanism 11 moves downward with respect to the water stop chamber 101 to the communication position of the water stop chamber 101. The first sealing ring 12 is separated from the first protrusion 1010, and the first sealing ring 12 controls the water stopping cavity 101 to open the first channel 110, and at the moment, the check valve judges that the pressure difference between two ends is large, and controls the second channel 111 to be opened, so that the conduction function of the water stopping component 1 is realized.

Based on the above-described embodiment, in one example, as shown in fig. 1 to 4, the water stop mechanism 11 includes: a water stop housing 112 and a fixing base 113.

Wherein, the water stop shell 112 is a shell structure, the fixed base 113 is connected with the water stop shell 112 through a third elastic member 114, and the third elastic member 114 can adopt a spring; the water stop housing 112 and the fixing base 113 are constructed with a second passage 111 therein, and the water stop chamber 101 is constructed with a first passage 110 therein. In other embodiments, the second passage 111 may also be configured in the water stop housing 112 or the stationary base 113. Since the fixing base 113 is connected to the water-stop housing 112 through the third elastic member 114, the water-stop housing 112 can move relative to the fixing base 113.

When the filter element is found to be required to be pulled out and replaced, the water stopping component 1 can be detached from the bypass seat 2, and the water purifying assembly 100 is in a detached state. The pressure applied to the water stop shell 112 by the bypass seat 2 is cancelled, under the condition that the fixed base 113 is fixed, the third elastic piece 114 drives the water stop shell 112 to move to the blocking position of the water stop cavity 101, the water stop shell 112 blocks the first channel 110 under the action of the third elastic piece 114, the water stop shell 112 moves upwards relative to the water stop cavity 101, at the moment, the water stop cavity 101 blocks the first channel 110, the check valve 115 judges that the pressure difference between two ends is smaller, and then the second channel 111 is controlled to be blocked, so that the water stop function of the water stop component 1 is realized.

When the water stop member 1 is found to be mounted on the bypass receptacle 2, the water purification assembly 100 is in the assembled state at this time, the bypass receptacle 2 applies downward pressure to the water stop housing 112, and the third elastic member 114 is deformed by pressure with the stationary base 113 fixed, and the water stop housing 112 moves to the communication position of the water stop chamber 101. The water stopping mechanism 11 moves downwards relative to the water stopping cavity 101, at this time, the water stopping cavity 101 opens the first channel 110, and when the check valve judges that the pressure difference between two ends is large, the second channel 111 is controlled to be opened, so that the conduction function of the water stopping component 1 is realized.

In order to stop the movement of the water-stop housing 112, in this embodiment, the fixing base 113 is provided with a second protrusion 1130, and the water-stop housing 112 is provided with an assembling opening 1120 corresponding to the second protrusion 1130. The water stop housing 112 is movably coupled to the fixing base 113 through the second protrusion 1130 and the fitting port 1120.

Under the condition that the water quality purifying assembly 100 is in a disassembly state, the pressure applied by the bypass seat 2 to the water stopping shell 112 is cancelled, under the condition that the fixed base 113 is fixed, the third elastic piece 114 drives the water stopping shell 112 to move, the third elastic piece 114 drives the second protrusion 1130 to move to the top end of the assembly port 1120, under the limit of the assembly port 1120, the water stopping shell 112 moves to the blocking position of the water stopping cavity 101, the water stopping cavity 101 blocks the first channel 110, the check valve 115 judges that the pressure difference at two ends is smaller, the second channel 111 is controlled to be blocked, and the water stopping function of the water stopping component 1 is realized.

In the state that the water purification assembly 100 is in the assembled state, the bypass receptacle 2 applies downward pressure to the water stop housing 112, and in the state that the fixing base 113 is fixed, the third elastic member 114 is deformed by pressure, the water stop housing 112 moves, and the second protrusion 1130 moves to the bottom end of the assembly port 1120. Under the limit of the assembly port 1120, the water stop housing 112 moves to the communication position of the water stop cavity 101, so that the water stop cavity 101 opens the first channel 110, and if the check valve determines that the pressure difference between two ends is large, the second channel 111 is controlled to be opened, so as to realize the conduction function of the water stop component 1.

In this embodiment, the water stop housing 112 is further configured with a receiving cavity, the fixed base 113 is movably disposed in the receiving cavity, one end of the third elastic member 114 is connected to the top surface of the receiving cavity, and the other end of the third elastic member 114 is connected to the fixed base 113.

In the following, a bypass seat 2 is proposed according to an embodiment of the application, which bypass seat 2 is intended to be detachably arranged on a cartridge housing, in connection with fig. 6 to 9.

Wherein, bypass seat 2 includes: a spool mechanism 22 and a seat body 21. The seat body 21 is a hollow housing structure, and a distribution chamber 212, a bypass chamber 211, and a working chamber 215 are configured in the seat body 21. Bypass chamber 211 communicates with working chamber 215 through distribution chamber 212. The bypass receptacle 2 is adapted to be removably coupled to the cartridge housing via the working chamber 215, and the water purification assembly 100 has a disassembled state and an assembled state. The spool mechanism 22 is movably disposed in the dispensing chamber 212 to switch between a first position and a second position; the seat body 21 is provided with a water inlet 213 and a water outlet 214.

As shown in fig. 7, when the filter element needs to be pulled out and replaced, the filter element housing can be detached from the bypass seat 2, and the filter element housing is disconnected from the working chamber 215, so that the water purification assembly 100 is in a detached state, and in order to ensure the normal operation of the waterway system, the valve element mechanism 22 is moved to the first position by adjusting the position of the valve element mechanism 22 in the distribution chamber 212, the valve element mechanism 22 is moved to block the distribution chamber 212 and the working chamber 215, and the distribution chamber 212 and the bypass chamber 211 are utilized to communicate the water inlet 213 and the water outlet 214. Therefore, water flowing in from the tap water pipe enters the distribution cavity 212 through the water inlet 213, then enters the bypass cavity 211 from the distribution cavity 212, and finally enters other mechanisms from the water outlet 214, so that the smoothness of a waterway is ensured when the filter element is replaced.

Therefore, the water flowing in from the tap water pipe enters the distribution cavity 212 through the water inlet 213, then enters the water stopping component through the working cavity 215, is filtered by the filter element, finally enters other mechanisms through the water outlet 214, and is purified through the water quality purifying assembly 100, so that the normal operation of the whole waterway system is ensured.

In one example, as shown in fig. 5 to 8, a water inlet cavity 2121 and a water outlet cavity 2122 are configured in the distribution cavity 212, the water inlet cavity 2121 communicates with the water inlet 213, the water outlet cavity 2122 communicates with the water outlet 214, one end of the bypass cavity 211 communicates with the working cavity 215 through the water inlet cavity 2121, and the other end of the bypass cavity 211 communicates with the working cavity 215 through the water outlet cavity 2122.

The first water inlet is provided at the bottom of the water outlet cavity 2122 and the second water inlet is provided at the top of the water outlet cavity 2122. The second water outlet communicates with the second water inlet through the bypass cavity 211. The first water outlet is connected to the working chamber 215 and corresponds to the inlet of the water purifying assembly 100. The first water inlet is used for connecting the working chamber 215 and corresponds to the outlet of the water purification assembly 100.

For ease of control, the spool mechanism 22 includes: a first jack 221 and a second jack 222.

The second ejector 222 is used for controlling the distribution of the water outlet cavity 2122, and the second ejector 222 is movably arranged in the water outlet cavity 2122.

In this embodiment, an inlet chamber 2121 is disposed at the inlet, an outlet chamber 2122 is disposed at the outlet, the inlet chamber 2121 controls the connection relationship with the bypass chamber 211 or the working chamber 215 through a first ejector rod 221, and the outlet chamber 2122 controls the connection relationship with the bypass chamber 211 or the working chamber 215 through a second ejector rod 222.

Because the filter element housing is connected with the bypass seat 2 through the working cavity 215, and the water quality purifying component 100 is partially arranged in the working cavity 215, at least one part of the first ejector rod 221 and the second ejector rod 222 is arranged in the working cavity 215 in order to conveniently complete the state switching in the disassembling process, so that the first ejector rod 221 and the second ejector rod 222 can be pushed by the water quality purifying component 100 when the water quality purifying component 100 is installed.

Specifically, as shown in fig. 7, when the filter element is found to be required to be pulled out and replaced, the filter element housing can be detached from the bypass seat 2, and since the first ejector rod 221 and the second ejector rod 222 are disposed in the distribution chamber 212, the water quality purifying assembly 100 is disconnected from the working chamber 215, the first ejector rod 221 and the second ejector rod 222 are separated from the water quality purifying assembly 100, the water quality purifying assembly 100 is in a detached state, and in order to ensure normal operation of the waterway system, the first ejector rod 221 and the second ejector rod 222 are separated from the filter element housing, the first ejector rod 221 moves downwards, the first ejector rod 221 blocks the first water outlet, and meanwhile, the first ejector rod 221 controls to be communicated with the water inlet 213 and the second water outlet. The second push rod 222 moves downward, the second push rod 222 blocks the first water inlet, and the second push rod 222 controls communication between the drain outlet 214 and the second water inlet. Therefore, water flowing in from the tap water pipe can enter the water inlet cavity 2121 through the water inlet 213, enter the bypass cavity 211 from the second water outlet of the water inlet cavity 2121, enter the second water inlet of the water outlet cavity 2122 from the bypass cavity 211, and finally enter other mechanisms through the water outlet 214, so that the water path is kept smooth when the filter element is replaced.

As shown in fig. 8, when the cartridge housing is mounted on the bypass receptacle 2, the water purifying assembly 100 is in an assembled state, since the first jack 221 and the second jack 222 are disposed in the distribution chamber 212, and the water stop member 1 is communicated with the working chamber 215 at this time, the first jack 221 and the second jack 222 are in contact with the water stop member 1, and the position of the first jack 221 in the water inlet chamber 2121 and the position of the second jack 222 in the water outlet chamber 2122 can be adjusted by pressing the first jack 221 and the second jack 222 by the cartridge housing of the water stop member 1. In the process, the first ejector rod 221 moves upwards, the first ejector rod 221 blocks the second water outlet, and meanwhile, the first ejector rod 221 is controlled to be communicated with the water inlet 213 and the first water outlet; the second push rod 222 moves upward, the second push rod 222 blocks the second water inlet, and the second push rod 222 controls to communicate the water outlet 214 with the first water inlet. Therefore, the water flowing in from the tap water pipe can enter the water inlet cavity 2121 through the water inlet 213, enter the working cavity 215 through the first water outlet of the water inlet cavity 2121, then enter the first water inlet of the water outlet cavity 2122 through the working cavity 215 after being filtered by the water stopping component through the filter element, finally enter other mechanisms through the water outlet 214, and the water is purified through the water quality purifying assembly 100, so that the normal operation of the whole waterway system is ensured.

Further, the water inlet chamber 2121 includes: a first water inlet chamber 2123 and a second water inlet chamber 2124 communicating with each other. The first water outlet is provided on the first water inlet 2123 and the second water outlet is provided on the second water inlet 2124.

The first push rod 221 is movable in the first water inlet cavity 2123 and the second water inlet cavity 2124; the second push rod 222 is movable in the first and second outlet chambers 2125, 2126. When the first ejector 221 moves in the first water inlet 2123 and the second water inlet 2124, the second water outlet can be blocked by the movement of the position, so that the water inlet 213 and the first water outlet are controlled to be communicated, or the first water outlet is blocked, so that the water inlet 213 and the second water outlet are controlled to be communicated. When the second ejector 222 moves in the first water outlet cavity 2125 and the second water outlet cavity 2126, the first water inlet can be blocked by the movement of the position, so that the water outlet 214 and the second water inlet are controlled to be communicated, or the second water inlet is blocked, so that the water outlet 214 and the first water inlet are controlled to be communicated.

Specifically, after the first and second push rods 221 and 222 are separated from the water stop member, the first push rod 221 moves downward, and when the first push rod 221 moves to the first water outlet position of the bottom of the first water inlet 2123, the first push rod 221 blocks the first water outlet, and simultaneously the first push rod 221 moves to the bottom of the second water inlet 2124 to expose the second water outlet, whereby the first push rod 221 controls communication between the water inlet 213 and the second water outlet. Meanwhile, the second ejector rod 222 moves downward, when the second ejector rod 222 moves to the first water inlet position at the bottom of the first water outlet cavity 2125, the second ejector rod 222 blocks the first water inlet, and simultaneously the second ejector rod 222 moves to the bottom of the second water outlet cavity 2126 to expose the second water inlet, and the second ejector rod 222 controls to communicate the water outlet 214 with the second water inlet.

After the first ejector rod 221 and the second ejector rod 222 are in contact with the water stopping component, the position of the first ejector rod 221 in the water inlet cavity 2121 and the position of the second ejector rod 222 in the water outlet cavity 2122 can be adjusted by pressing the first ejector rod 221 and the second ejector rod 222 by the water purifying assembly 100. When the first ejector rod 221 moves to the second water outlet position at the top of the second water inlet cavity 2124, the first ejector rod 221 blocks the second water outlet, and meanwhile, the first ejector rod 221 moves to expose the first water outlet, and the first ejector rod 221 controls communication between the water inlet 213 and the first water outlet. Meanwhile, the second ejector 222 moves upward, and when the second ejector 222 moves to the second water inlet at the top of the second water outlet cavity 2126, the second ejector 222 blocks the second water inlet, and at the same time, the second ejector 222 moves to expose the first water inlet, and the second ejector 222 controls to communicate the water outlet 214 with the first water inlet.

As shown in fig. 1 to 3, when the filter element is found to be required to be pulled out and replaced, the water stop member 1 can be detached from the bypass seat 2, and the filter element housing 10 is separated from the bypass seat 2; the water stop mechanism 11 moves to the blocking position of the water stop chamber 101. As shown in fig. 1, the water stopping mechanism 11 moves upward relative to the water stopping cavity 101, at this time, the water stopping cavity 101 blocks the first channel 110, at this time, the check valve 115 determines that the pressure difference between two ends is smaller, and then the second channel 111 is controlled to be blocked, so as to realize the water stopping function of the water stopping component 1. As shown in fig. 7, in order to ensure the normal operation of the waterway system, the bypass seat 2 communicates with the water inlet 213 and the water outlet 214 during this process; therefore, water flowing in from the tap water pipe enters the bypass seat 2 through the water inlet 213 and enters other mechanisms through the water outlet 214, so that the water path is kept smooth when the filter element is replaced. At this time, the tap water cannot be filtered, but the tap water may be fed into the valve body 200 through the bypass receptacle 2 and respectively introduced into the refrigerating and ice-making machine 500, the dispenser 300, and the freezing and ice-making machine 600 to complete the corresponding ice-making work.

As shown in fig. 4, when the water stop member 1 is found to be mounted on the bypass receptacle 2, the water purification assembly 100 is in an assembled state at this time, and the water stop mechanism 11 is moved to the communication position of the water stop chamber 101. As shown in fig. 2, the water stop mechanism 11 moves downward relative to the water stop cavity 101, at this time, the water stop cavity 101 is opened to the first channel 110, at this time, the check valve determines that the pressure difference between the two ends is large, and then the second channel 111 is controlled to be opened to realize the conduction function of the water stop component 1. As shown in fig. 8, the bypass receptacle 2 communicates with the water inlet 213 and the water outlet 214 through the first passage 110 and the second passage 111 at this time. From this, the water that the running water pipe flowed in gets into bypass seat 2 through water inlet 213, then water is filtered by the filter core through stagnant water mechanism 11, and finally gets into other mechanisms by bypass seat 2's outlet 214, purifies water through water purification subassembly 100, guarantees that whole waterway system normally works. At this time, tap water enters the bypass seat 2, passes through the water stop member 1, is filtered by the filter element, and is discharged to the bypass seat 2. The respective ice making operations are performed by the valve body 200 being introduced into the refrigerating and ice making machine 500, the dispenser 300, and the freezing and ice making machine 600 through the first water supply pipe 510, the water outlet pipe 310, and the second water supply pipe 610, respectively.

According to the refrigeration equipment provided by the embodiment of the invention, the first channel and the second channel are constructed in the water stop mechanism, and the one-way valve is arranged in the second channel, so that under the condition of being in a disassembled state, the water stop mechanism moves to the blocking position of the water stop cavity, the first channel is blocked by the water stop cavity, the second channel is blocked by judging the pressure difference by the one-way valve, the problem that water in the filter element flows out during the process of pulling out and replacing the filter element is avoided, and the core replacing experience of a user is improved. Meanwhile, the bypass seat is communicated with the water inlet and the water outlet to ensure the smoothness of the waterway when the filter element is replaced. And under the condition that the water stopping component is in an assembled state, the water stopping mechanism moves to the communicating position of the water stopping cavity, the first channel is opened by utilizing the water stopping cavity, the second channel is communicated by utilizing the judgment of the one-way valve on the pressure difference, and the normal operation of the filter element is ensured. Meanwhile, the bypass seat is communicated with the water inlet and the water outlet through the first channel and the second channel to purify water, so that the whole waterway system is ensured to work. The problem of poor user experience caused by the fact that the plug is independently configured to keep the use of the waterway is avoided.
