Description

Technical Field

[0001] This invention relates to the field of ice and water technology, and more particularly to water-stopping components, water purification components, and refrigeration equipment. Background Technology

[0002] When existing filter cartridges are pulled out and replaced, water inside the cartridges is easily spilled due to their open internal structure. Users need to clean up the spilled water. In addition, filter cartridges often contain untreated dirty water, which also spills out when the filter cartridge is pulled out and replaced, increasing the user's cleaning efforts. The dirty water also causes a poor user experience. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in related technologies. To this end, this invention proposes a water-stopping component to prevent internal water from flowing out when the filter cartridge is pulled out and replaced, thereby improving the user's filter cartridge replacement experience.

[0004] The present invention also proposes a water purification component and a refrigeration device.

[0005] According to a first aspect of the present invention, a water-stopping component includes: a filter cartridge housing having a water-stopping cavity having a first channel therein; a water-stopping mechanism movably disposed in the water-stopping cavity for switching between a blocking position and a connecting position, the water-stopping mechanism having a second channel; the second channel being provided with a one-way valve for switching on and off based on a pressure difference; in the blocking position, the water-stopping mechanism blocks the first channel, and the one-way valve blocks the second channel; in the connecting position, the water-stopping mechanism moves to the connecting position of the water-stopping cavity, the water-stopping mechanism opens the first channel, and the one-way valve opens the second channel.

[0006] According to an embodiment of the present invention, the water-stopping component provided by the present invention constructs a first channel and a second channel, and sets a one-way valve in the second channel, so that the water-stopping mechanism moves to the blocking position of the water-stopping chamber, thereby blocking the first channel by the water-stopping mechanism and blocking the second channel by the one-way valve, so as to avoid the problem of internal water flowing out when the filter element is pulled out and replaced.

[0007] According to one embodiment of the present invention, the water-stopping component further includes: a first sealing ring, sleeved on the water-stopping mechanism and located between the water-stopping mechanism and the filter element housing; when the water-stopping mechanism is in the blocking position, the water-stopping cavity cooperates with the first sealing ring to block the first channel; when the water-stopping mechanism is in the communicating position, the first sealing ring opens the first channel. By providing the first sealing ring, the state switching can be achieved simply by moving the water-stopping mechanism within the water-stopping cavity.

[0008] According to one embodiment of the present invention, a first protrusion is provided in the water-stopping cavity; when the water-stopping mechanism is in the blocking position, the first sealing ring abuts against the first protrusion, and the first sealing ring forms a first sealing surface at the first protrusion; when the water-stopping mechanism is in the communicating position, the first sealing ring disengages from the first protrusion. By providing the first protrusion, the first sealing ring forms a sealing surface in the water-stopping cavity, thereby achieving the corresponding state switching.

[0009] According to one embodiment of the present invention, the water-stopping mechanism includes: a water-stopping housing; a fixed base connected to the water-stopping housing via an elastic element; a second channel is formed in the fixed base and the water-stopping housing; when the water-stopping mechanism is in the blocking position, the water-stopping housing blocks the first channel under the action of the elastic element; when the water-stopping mechanism is in the communicating position, the water-stopping housing opens the water-stopping cavity. By providing the water-stopping housing and the fixed base, the water-stopping housing can move on the fixed base under the drive of the elastic element to achieve corresponding state switching.

[0010] According to one embodiment of the present invention, the fixed base is provided with a second protrusion, and the water-stop shell is provided with an assembly port corresponding to the second protrusion; the water-stop shell is movably connected to the fixed base through the second protrusion and the assembly port. When the water-stop mechanism is in the blocking position, the second protrusion is held at one end of the assembly port under the action of the elastic member; when the water-stop mechanism is in the communicating position, the second protrusion moves to the other end of the assembly port. By providing the second protrusion and the assembly port, the movement range of the water-stop shell is limited, ensuring the movement position of the water-stop shell during state switching.

[0011] According to one embodiment of the present invention, the waterproof outer shell is configured with a receiving cavity, the fixed base is movably disposed in the receiving cavity, one end of the elastic member is connected to the top surface of the receiving cavity, and the other end of the elastic member is connected to the fixed base.

[0012] According to one embodiment of the present invention, the water-stopping mechanism further includes: a second sealing ring, sleeved on the fixed base and located between the water-stopping housing and the fixed base, for ensuring sealing during the movement of the water-stopping mechanism.

[0013] According to one embodiment of the present invention, the water-stopping cavity is provided with a guide groove, and the water-stopping mechanism is at least partially engaged in the guide groove. The water-stopping mechanism is movably disposed in the guide groove along the arrangement direction of the guide groove, so that the water-stopping mechanism can move within a set position.

[0014] According to one embodiment of the present invention, the first channel is a water inlet channel and the second channel is a water outlet channel; or, the first channel is a water outlet channel and the second channel is a water inlet channel, so as to meet different user needs.

[0015] According to a second aspect of the present invention, a water purification assembly includes: a filter element and a water-stopping component; the filter element is disposed within the filter element housing; when the water-stopping mechanism is in the communicating position, both ends of the filter element are connected to the outside through the first channel and the second channel, respectively. This water purification assembly, by constructing the first channel and the second channel and providing a one-way valve in the second channel, ensures that when the water-stopping mechanism is in the blocking position, it moves to the blocking position of the water-stopping chamber, blocking the first channel with the water-stopping mechanism and the second channel with the one-way valve, thereby preventing internal water leakage when the filter element is pulled out and replaced, and improving the user's filter replacement experience.

[0016] A refrigeration device according to a third aspect of the present invention includes: a valve body and a water purification component; the inlet of the valve body is connected to either the first channel or the second channel. This refrigeration device constructs a first channel and a second channel, and provides a one-way valve in the second channel. When the water-stopping mechanism is in the blocking position, it moves to the blocking position of the water-stopping chamber, blocking the first channel using the water-stopping mechanism and the second channel using the one-way valve. This prevents internal water from flowing out when the filter element is pulled out and replaced, improving the user's filter replacement experience.

[0017] According to one embodiment of the present invention, the refrigeration equipment further includes: a distributor connected to the outlet of the valve body via a water outlet pipe; a refrigerated ice maker connected to the outlet of the valve body via a first water supply pipe; and a frozen ice maker connected to the outlet of the valve body via a second water supply pipe, so that the water purification component can supply water to multiple units simultaneously.

[0018] According to one embodiment of the present invention, the refrigeration equipment includes: a housing; the housing defines a freezer compartment and a refrigerator compartment; the water purification component, the valve body, the refrigerator ice maker and the distributor are all disposed in the refrigerator compartment; the freezer ice maker is disposed in the freezer compartment.

[0019] The above-mentioned one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects: the water-stopping component cuts off the passage between the inlet / outlet and the internal water when it is pulled out, and the inlet / outlet is effectively connected to the external water passage when it is assembled, thus effectively preventing dirty water from escaping from the inside of the filter element when it is replaced, thereby improving the user experience.

[0020] Furthermore, by setting a first sealing ring and a first protrusion, the state can be switched by moving the water-stopping mechanism in the water-stopping cavity.

[0021] Furthermore, by setting a water-stop shell and a fixed base, the water-stop shell can move on the fixed base under the drive of the elastic element to achieve corresponding state switching. The structure is efficient and highly reliable.

[0022] Furthermore, by setting a second protrusion and an assembly port, the movement range of the water-stop shell is limited, ensuring the movement position of the water-stop shell during state switching.

[0023] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0035] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0040] The following is combined with Figures 1 to 5 The water-stopping component 1 proposed according to the embodiments of this application is used in conjunction with a filter element and includes: a filter element housing 10 and a water-stopping mechanism 11.

[0041] The filter cartridge housing 10 has a hollow structure and contains a water-stopping cavity 101. A water-stopping mechanism 11 is movably disposed within the water-stopping cavity 101, which contains a first channel 110 located between the filter cartridge housing 10 and the water-stopping mechanism 11. The water-stopping mechanism 11 also contains a second channel 111. To prevent internal water leakage during filter cartridge removal and replacement, the water-stopping mechanism 11 can switch between a blocking position and a connecting position. The second channel 111 contains a one-way valve 115 for switching on and off based on pressure difference. The one-way valve 115 not only restricts the water flow direction but also switches on and off based on pressure difference.

[0042] like Figure 4 As shown, the water-stopping component 1 provided in this embodiment is detachably connected to the bypass connector 2. When it is found that the filter element needs to be pulled out and replaced, the water-stopping component 1 can be removed from the bypass connector 2. At this time, the water-stopping component 1 is in a disassembled state, and the water-stopping mechanism 11 is moved to the blocking position of the water-stopping chamber 101. Figure 2As shown, the water-stopping mechanism 11 moves upward relative to the water-stopping chamber 101. At this time, the water-stopping chamber 101 closes the first channel 110. At this time, the one-way valve 115 judges that the pressure difference between the two ends is small, and then controls the blocking of the second channel 111 to realize the water-stopping function of the water-stopping component 1.

[0043] When it is discovered that the water-stopping component 1 is installed on the bypass connector 2, the water-stopping component 1 is in the assembled state, and the water-stopping mechanism 11 moves to the communication position of the water-stopping cavity 101. For example... Figure 3 As shown, the water-stopping mechanism 11 moves downward relative to the water-stopping cavity 101. At this time, the water-stopping mechanism 101 opens the first channel 110. At this time, the one-way valve judges that the pressure difference between the two ends is large, and then controls the opening of the second channel 111 to realize the opening function of the water-stopping component 1.

[0044] The water-stopping component provided in this embodiment of the invention includes a filter cartridge housing and a water-stopping mechanism. By constructing a first channel and a second channel within the water-stopping mechanism, and installing a one-way valve in the second channel, when the filter cartridge is in the disassembled state, the water-stopping mechanism moves to the blocking position of the water-stopping chamber. The water-stopping mechanism blocks the first channel, and the one-way valve, based on pressure difference, blocks the second channel, thus preventing internal water leakage when the filter cartridge is pulled out or replaced, improving the user's filter cartridge replacement experience. When the water-stopping component is in the assembled state, the water-stopping mechanism moves to the connecting position of the water-stopping chamber. The water-stopping mechanism opens the first channel, and the one-way valve, based on pressure difference, connects the second channel, ensuring the normal operation of the filter cartridge.

[0045] In one example, such as Figures 1 to 4 As shown, the water-stopping component 1 also includes a first sealing ring 12. The first sealing ring 12 may be a rubber sealing ring. The first sealing ring 12 is sleeved on the water-stopping mechanism 11, and the first sealing ring 12 is located between the water-stopping mechanism 11 and the filter element housing 10.

[0046] In this embodiment, the water-stopping mechanism 11 can move up and down relative to the water-stopping cavity 101, and the first sealing ring 12 is disposed on the water-stopping mechanism 11. Therefore, the first sealing ring 12 can move up and down relative to the water-stopping cavity 101.

[0047] When it is discovered that the filter cartridge needs to be removed and replaced, such as Figure 2 As shown, the water-stopping component 1 can be removed from the bypass connector 2, at which point the water-stopping component 1 is in a disassembled state. The water-stopping mechanism 11 moves upward relative to the water-stopping cavity 101, and the water-stopping mechanism 11 moves to the blocking position of the water-stopping cavity 101. The first sealing ring 12 moves to a part in the water-stopping cavity 101, and the first sealing ring 12 directly forms a sealing surface with the inner wall of the water-stopping cavity 101. The water-stopping cavity 101 cooperates with the first sealing ring 12 to block the first channel 110. At this time, the one-way valve 115 judges that the pressure difference between the two ends is small, and then controls the blocking of the second channel 111, thereby realizing the water-stopping function of the water-stopping component 1.

[0048] like Figure 3 As shown, when the water-stopping component 1 is in the assembled state, the water-stopping mechanism 11 moves to the connected position of the water-stopping cavity 101. The sealing surface between the first sealing ring 12 and the inner wall of the water-stopping cavity 101 is released, and the first sealing ring 12 opens the first channel 110. At this time, the one-way valve determines that the pressure difference between the two ends is large, and then controls the opening of the second channel 111 to realize the conduction function of the water-stopping component 1.

[0049] like Figure 5 As shown, a third sealing ring 14 can also be provided on the water-stopping mechanism 11. The third sealing ring 14 can be a rubber sealing ring. Each third sealing ring 14 is fitted on the water-stopping mechanism 11. The third sealing ring 14 is also located between the water-stopping mechanism 11 and the filter element housing 10. The third sealing ring 14 is generally set at the edge of the opening of the water-stopping cavity 101 to ensure that the water-stopping components are in the state switching process.

[0050] Specifically, such as Figures 1 to 3 As shown, a first protrusion 1010 is provided in the water-stopping cavity 101. The first protrusion 1010 is an annular protrusion.

[0051] When the water-stopping component 1 is in the disassembled state, the water-stopping mechanism 11 moves upward relative to the water-stopping cavity 101, and the water-stopping mechanism 11 moves to the blocking position of the water-stopping cavity 101. The first sealing ring 12 abuts against the first protrusion 1010, and the first sealing ring 12 forms a first sealing surface at the first protrusion 1010. At this time, the first sealing surface is used to seal and block the first channel 110. At this time, the one-way valve 115 determines that the pressure difference between the two ends is small, and then controls the blocking of the second channel 111, thereby realizing the water-stopping function of the water-stopping component 1.

[0052] When the water-stopping component 1 is in the assembled state, the water-stopping mechanism 11 moves downward relative to the water-stopping cavity 101, moving to the communication position of the water-stopping cavity 101. The first sealing ring 12 disengages from the first protrusion 1010, and the first sealing ring 12 controls the water-stopping mechanism 101 to conduct the first channel 110. At this time, the one-way valve determines that the pressure difference between the two ends is large, and then controls the conduction of the second channel 111, realizing the conduction function of the water-stopping component 1.

[0053] Based on the above embodiments, in one example, such as Figures 1 to 5 As shown, the water-stopping mechanism 11 includes: a water-stopping housing 112 and a fixed base 113.

[0054] The water-stop shell 112 is a shell structure, and the fixed base 113 is connected to the water-stop shell 112 via an elastic element 114, which can be a spring. A second channel 111 is constructed in both the water-stop shell 112 and the fixed base 113, and a first channel 110 is constructed in the water-stop cavity 101. In other embodiments, the second channel 111 can also be constructed in either the water-stop shell 112 or the fixed base 113. Since the fixed base 113 is connected to the water-stop shell 112 via the elastic element 114, the water-stop shell 112 can move relative to the fixed base 113.

[0055] When it is found that the filter element needs to be removed and replaced, the water-stopping component 1 can be removed from the bypass connector 2. At this time, the water-stopping component 1 is in the disassembled state. The pressure applied by the bypass connector 2 to the water-stopping housing 112 is removed. With the fixed base 113 fixed, the elastic element 114 drives the water-stopping housing 112 to move to the blocking position of the water-stopping cavity 101. Under the action of the elastic element 114, the water-stopping housing 112 blocks the first channel 110. The water-stopping housing 112 moves upward relative to the water-stopping cavity 101. At this time, the water-stopping mechanism 101 blocks the first channel 110. The one-way valve 115 judges that the pressure difference between the two ends is small, and then controls the blocking of the second channel 111, realizing the water-stopping function of the water-stopping component 1.

[0056] When the water-stopping component 1 is installed on the bypass connector 2, it is in the assembled state. The bypass connector 2 applies downward pressure to the water-stopping housing 112. With the fixed base 113 stationary, the elastic element 114 deforms under pressure, and the water-stopping housing 112 moves to the communication position of the water-stopping cavity 101. The water-stopping mechanism 11 moves downward relative to the water-stopping cavity 101. At this time, the water-stopping mechanism 101 opens the first channel 110. The one-way valve determines that the pressure difference between the two ends is large, and then controls the opening of the second channel 111, realizing the conduction function of the water-stopping component 1.

[0057] To restrict the movement of the water-stop shell 112, in this embodiment, the fixed base 113 is provided with a second protrusion 1130, and the water-stop shell 112 is provided with a corresponding mounting opening 1120 for the second protrusion 1130. The water-stop shell 112 is movably connected to the fixed base 113 through the second protrusion 1130 and the mounting opening 1120.

[0058] When the water-stopping component 1 is in the disassembled state, the pressure applied by the bypass connector 2 to the water-stopping housing 112 is released. With the fixed base 113 stationary, the elastic element 114 drives the water-stopping housing 112 to move. The elastic element 114 drives the second protrusion 1130 to move to the top of the assembly port 1120. The second protrusion 1130 is held at the top of the assembly port 1120 by the action of the elastic element 114. Under the limitation of the assembly port 1120, the water-stopping housing 112 moves to the blocking position of the water-stopping cavity 101, so that the water-stopping cavity 101 closes the first channel 110. The one-way valve 115 determines that the pressure difference between the two ends is small, and then controls the blocking of the second channel 111, thereby realizing the water-stopping function of the water-stopping component 1.

[0059] When the water-stopping component 1 is in the assembled state, the bypass connector 2 applies downward pressure to the water-stopping housing 112. With the fixed base 113 stationary, the elastic element 114 deforms under pressure, causing the water-stopping housing 112 to move, and the second protrusion 1130 moves to the bottom end of the assembly port 1120. Under the limitation of the assembly port 1120, the water-stopping housing 112 moves to the communication position of the water-stopping cavity 101, so that the water-stopping mechanism 101 opens the first channel 110. If the one-way valve determines that the pressure difference between the two ends is large, it controls the opening of the second channel 111, thereby realizing the conduction function of the water-stopping component 1.

[0060] In this embodiment, the water-stop shell 112 also has a receiving cavity, and the fixed base 113 is movably disposed in the receiving cavity. One end of the elastic member 114 is connected to the top surface of the receiving cavity, and the other end of the elastic member 114 is connected to the fixed base 113. When the elastic member 114 is deformed under pressure, the fixed base 113 can be completely accommodated in the receiving cavity. After the elastic member 114 returns to its initial shape, the water-stop shell 112 is pushed upward by the elastic member 114 and moves in the water-stop cavity 101, and the fixed base 113 is exposed in the receiving cavity.

[0061] To ensure a sealing effect, the water-stopping mechanism 11 also includes a second sealing ring 13, which is sleeved on the fixed base 113 and located between the water-stopping housing 112 and the fixed base 113. The second sealing ring 13 can be a rubber sealing ring to ensure sealing during the movement of the water-stopping mechanism 11.

[0062] Based on the above embodiments, in one example, such as Figures 1 to 3 As shown, to allow the water-stopping mechanism 11 to move within a set position, a guide groove 1001 is provided in the water-stopping cavity 101. The water-stopping mechanism 11 is at least partially engaged in the guide groove 1001, and the water-stopping mechanism 11 is movably disposed in the guide groove 1001 along the arrangement direction of the guide groove 1001. The guide groove 1001 can be configured in shape and direction as needed. In this embodiment, the guide groove 1001 is arranged along the axial direction of the water-stopping cavity 101, allowing the water-stopping mechanism 11 to move along the axial direction of the water-stopping cavity 101.

[0063] When the water-stopping component 1 is in the disassembled state, the water-stopping mechanism 11 moves along the guide groove 1001 to the blocking position of the water-stopping cavity 101. For example... Figure 1 As shown, the water-stopping mechanism 11 moves upward relative to the water-stopping cavity 101, causing the water-stopping cavity 101 to close the first channel 110. The one-way valve 115 determines that the pressure difference between the two ends is small, and then controls the blocking of the second channel 111, thereby realizing the water-stopping function of the water-stopping component 1.

[0064] When it is discovered that the water-stopping component 1 is installed on the bypass connector 2, the water-stopping component 1 is in the assembled state, and the water-stopping mechanism 11 moves along the guide groove 1001 to the communication position of the water-stopping cavity 101. Figure 2 As shown, the water-stopping mechanism 11 moves downward relative to the water-stopping cavity 101, so that the water-stopping mechanism 101 opens the first channel 110. If the one-way valve determines that the pressure difference between the two ends is large, it controls the opening of the second channel 111, thereby realizing the opening function of the water-stopping component 1.

[0065] According to user needs, such as Figure 6 As shown, the first channel 110 can be set as a water inlet channel and the second channel 111 as a water outlet channel, or the second channel 111 can be set as a water inlet channel and the first channel 110 as a water outlet channel.

[0066] like Figure 6 As shown, when the first channel 110 is the water inlet channel and the second channel 111 is the water outlet channel, if the water-stopping component 1 is in the assembled state, the water-stopping mechanism 101 opens the first channel 110, and the one-way valve 115 opens the second channel 111. Water enters the first channel 110 through the bypass connector 2, and the water filtered in the filter element is then discharged through the second channel 111 to the bypass connector 2.

[0067] When the second channel 111 is the water inlet channel and the first channel 110 is the water outlet channel, if the water-stopping component 1 is in the assembled state, the water-stopping mechanism 101 opens the first channel 110, and the one-way valve 115 opens the second channel 111. Water enters the second channel 111 through the bypass connector 2, and the water filtered in the filter element is then discharged from the first channel 110 to the bypass connector 2.

[0068] This invention also provides a water purification component, such as... Figures 1 to 6As shown, the water purification assembly includes a filter element 15 and a water-stopping component 1. The water-stopping component 1, used in conjunction with the filter element 15, includes a filter element housing 10 and a water-stopping mechanism 11. The filter element housing 10 is hollow, and a water-stopping cavity 101 is constructed within it. The filter element 15 is disposed within the filter element housing 10. The water-stopping mechanism 11 is movably disposed within the water-stopping cavity 101, which has a first channel 110 located between the filter element housing 10 and the water-stopping mechanism 11. The water-stopping mechanism 11 also has a second channel 111. The first channel 110 can be an inlet channel, and the second channel 111 an outlet channel, or vice versa. To prevent internal water leakage when the filter element 15 is removed or replaced, a one-way valve 115 is provided in the second channel 111 for switching on and off based on pressure difference. The one-way valve 115 is used not only to restrict the direction of water flow, but also to achieve on / off switching based on pressure difference.

[0069] like Figure 4 As shown, the water-stopping component 1 provided in this embodiment is detachably connected to the bypass connector 2. When it is found that the filter element 15 needs to be pulled out and replaced, the water-stopping component 1 can be removed from the bypass connector 2. At this time, the water-stopping component 1 is in a disassembled state, and the water-stopping mechanism 11 is moved to the blocking position of the water-stopping chamber 101. Figure 2 As shown, the water-stopping mechanism 11 moves upward relative to the water-stopping chamber 101. At this time, the water-stopping chamber 101 closes the first channel 110. When the one-way valve 115 determines that the pressure difference between the two ends is small, it controls the blocking of the second channel 111, thus realizing the water-stopping function of the water-stopping component 1. With the first channel 110 and the second channel 111 at both ends of the filter element 15 blocked, the filter element 15 stops filtering.

[0070] When it is discovered that the water-stopping component 1 is installed on the bypass connector 2, the water-stopping component 1 is in the assembled state, and the water-stopping mechanism 11 moves to the communication position of the water-stopping cavity 101. For example... Figure 2 As shown, the water-stopping mechanism 11 moves downward relative to the water-stopping chamber 101. At this time, the water-stopping mechanism 101 opens the first channel 110. The one-way valve determines that the pressure difference between the two ends is large, and then controls the opening of the second channel 111, realizing the opening function of the water-stopping component 1. The two ends of the filter element 15 are connected to the outside through the first channel 110 and the second channel 111 respectively. After water enters the first channel 110, it is first filtered by the filter element 15, and then discharged through the second channel 111.

[0071] The water purification component provided in this invention includes a filter cartridge housing and a water-stopping mechanism. By constructing a first channel and a second channel within the water-stopping mechanism, and installing a one-way valve in the second channel, the water-stopping mechanism moves to the blocking position of the water-stopping chamber when the filter cartridge is in the disassembled state. The water-stopping mechanism blocks the first channel, and the one-way valve, based on pressure difference, blocks the second channel, preventing internal water leakage when the filter cartridge is removed or replaced, thus improving the user's filter cartridge replacement experience. When the water-stopping component is in the assembled state, the water-stopping mechanism moves to the connecting position of the water-stopping chamber. The water-stopping mechanism opens the first channel, and the one-way valve, based on pressure difference, connects the second channel, ensuring the normal operation of the filter cartridge. This water purification component can simultaneously achieve water-stopping, anti-turbidity, and purification functions.

[0072] In one example, such as Figure 6 As shown, the filter element 15 includes: a supporting partition 153, a purification core material 151, and a core material housing 152 for housing the purification core material 151. The purification core material 151 is a water purification material. The core material housing 152 is used to divide the purification core material 151 into flow channels. Simultaneously, the core material housing 152 and the filter element housing 10 form a first channel 110. The fixed base 113 on the core material housing 152 provides radial support and further extends the water flow time, achieving first-in-first-out (FIFO). One end of the purification core material 151 is provided with a purification core material outlet end 1510, which is the sealed end of the purification core material 151, used to guide water from the flow channels in the purification core material to the second channel 111. The bottom of the core material housing 152 is provided with a supporting partition 153, which provides axial support and sealing for the purification core material. Simultaneously, a water flow channel and space are formed inside the supporting partition 153. The internal space, consisting of filter housing 10, core material housing 152, and support partition 153, not only extends the internal water flow path to facilitate first-in-first-out water flow, but also allows water to be stored within the space.

[0073] This invention also provides a refrigeration device, which can be a refrigerator, freezer, or water dispenser with refrigeration capabilities. Taking a refrigerator as an example... Figure 7 and Figure 8 As shown, the refrigerator includes a valve body 200 and a water purification component 100; the specific structure of the water purification component 100 can be referred to the above embodiment, and will not be repeated here.

[0074] The water purification component 100 is connected to a tap water pipe, and the inlet of the valve body 200 is connected to either the second channel or the first channel. When the first channel is the inlet channel and the second channel is the outlet channel, the inlet of the valve body 200 is connected to the second channel.

[0075] The refrigerator includes a distributor 300, a refrigerator ice maker 500, and a freezer ice maker 600. The distributor 300 is connected to the outlet of the valve body 200 via a water outlet pipe 310; the refrigerator ice maker 500 is connected to the outlet of the valve body 200 via a first water supply pipe 510; and the freezer ice maker 600 is connected to the outlet of the valve body 200 via a second water supply pipe 610. Thus, after tap water enters the water purification component 100, it can flow through the valve body 200 into the distributor 300, the refrigerator ice maker 500, and the freezer ice maker 600, respectively.

[0076] The refrigerator includes: a cabinet; the cabinet is divided into a freezer compartment 400 and a refrigerator compartment 700; a water purification component 100, a valve body 200, a refrigerator ice maker 500, and a distributor 300 are all located in the refrigerator compartment 700; a freezer ice maker 600 is located in the freezer compartment 400. Users can install the water purification component 100, valve body 200, refrigerator ice maker 500, and distributor 300 in the refrigerator compartment 700, using the temperature of the refrigerator compartment 700 to cool the internal water for supplying users with cold water or ice. The freezer ice maker 600 is located in the freezer compartment 400, using the temperature of the freezer compartment 400 to cool the internal water, allowing the freezer ice maker 600 to supply users with ice.

[0077] When it is discovered that the filter element needs to be removed and replaced, the water-stopping component 1 can be removed from the bypass connector 2. At this time, the water-stopping component 1 is in a disassembled state, and the water-stopping mechanism 11 can be moved to the blocking position of the water-stopping chamber 101. Figure 2 As shown, the water-stopping mechanism 11 moves upward relative to the water-stopping chamber 101. At this time, the water-stopping chamber 101 closes the first channel 110. The one-way valve 115 then determines that the pressure difference between the two ends is small and controls the blocking of the second channel 111, thus achieving the water-stopping function of the water-stopping component 1. The filter element is blocked between the first channel 110 and the second channel 111. At this time, tap water cannot enter the water purification component 100.

[0078] like Figure 3 As shown, when the water-stopping component 1 is installed on the bypass connector 2, the water-stopping component 1 is in the assembled state, and the water-stopping mechanism 11 moves to the communication position of the water-stopping cavity 101. Figure 3 As shown, the water-stopping mechanism 11 moves downward relative to the water-stopping chamber 101, thus opening the first channel 110. At this time, the one-way valve determines that the pressure difference between the two ends is large and controls the opening of the second channel 111, realizing the conduction function of the water-stopping component 1. The filter element connects the first channel 110 and the second channel 111. After tap water enters the first channel 110, it is first filtered by the filter element and then discharged through the second channel 111. Water from the valve body 200 is introduced into the refrigerated ice maker 500, the distributor 300, and the frozen ice maker 600 respectively through the first water supply pipe 510, the outlet pipe 310, and the second water supply pipe 610 to complete the corresponding ice-making work.

[0079] The refrigeration equipment provided in this embodiment of the invention includes a filter cartridge housing and a water-stopping mechanism. By constructing a first channel and a second channel within the water-stopping mechanism, when the filter cartridge is in a disassembled state, the water-stopping mechanism moves to the blocking position of the water-stopping cavity, blocking the first and second channels to prevent internal water leakage during filter cartridge removal and replacement, thus improving the user's filter cartridge replacement experience. When the water-stopping mechanism is in an assembled state, it moves to the connecting position of the water-stopping cavity, connecting the first and second channels to ensure the normal operation of the filter cartridge.

Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
