[0056] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0058] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0059] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0060] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the word "and / or" throughout the text means including three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0061] This invention proposes a device with water purification function, which can be configured as a water purifier, a water dispenser, a water softener and purifier combined machine, or a water purifier and heat purifier combined machine, etc.

[0062] Reference Figures 1 to 11 In this embodiment of the invention, the device with water purification function includes a housing 10, a filter assembly 20, a first water circuit board 30, and a booster pump 60. The filter assembly 20 is horizontally placed inside the housing 10. The filter assembly 20 includes a filter element body and a filter element mounting bracket 23. The filter element mounting bracket 23 has a first mounting cavity 2311 and a second mounting cavity 2321 arranged longitudinally side by side. The filter element body includes a first filter element 21 and a second filter element 22. The first filter element 21 is installed in the first mounting cavity 2311, and the second filter element 22 is installed in the second mounting cavity 2321. The first water circuit board 30 is connected to the filter element mounting bracket 23 and is located in the horizontal direction of the filter element mounting bracket 23. The booster pump 60 is arranged longitudinally side by side with the first water circuit board 30. The booster pump 60 and the first water circuit board 30 are located on the same side of the filter element mounting bracket 23, thus reliably reducing the overall height of the device.

[0063] The filter assembly 20 is installed horizontally inside the housing 10, which can effectively reduce the overall height of the filter assembly 20 and thus reduce the overall height of the equipment. The filter assembly 20 includes a filter element body and a filter element mounting bracket 23. The filter element body includes a first filter element 21 and a second filter element 22. The first filter element 21 can be configured as a composite filter element. One of the first filter element 21 and the second filter element 22 can be configured as a composite filter element. The composite filter element integrates at least a relatively independent pre-filter element and a post-filter element. The other of the first filter element 21 and the second filter element 22 can be configured as a reverse osmosis filter element. The assembly positions of the first filter element 21 and the second filter element 22 can be reasonably arranged according to the convenience of pipeline connection and the filtration effect of the first filter element 21 and the second filter element 22. It should be noted that, in order to ensure the filtration effect of the water purification equipment and meet the national standards for water quality, the composite filter and reverse osmosis filter are used to effectively intercept organic matter (such as methane and tetrachloromethane) and heavy metals in the water. The tap water entering the water purification equipment will first be filtered by the pre-filter, which will adsorb larger particles of impurities in the water. The water filtered by the pre-filter will then pass through the RO membrane of the reverse osmosis filter to remove most of the salt ions in the water. The filtered water after the reverse osmosis filter will be filtered by the post-filter to remove color and adjust before flowing to the user's end through the faucet.

[0064] The filter element mounting bracket 23 is provided with a first mounting cavity 2311 and a second mounting cavity 2321. Due to the horizontal placement of the filter assembly 20, the first mounting cavity 2311 and the second mounting cavity 2321 are horizontally positioned, and their openings are also located on the side of the filter element mounting bracket 23. At this time, the first filter element 21 is horizontally inserted into the first mounting cavity 2311, and the second filter element 22 is horizontally inserted into the second mounting cavity 2321, thereby achieving the assembly between the filter element body and the filter element mounting bracket 23. The horizontal laying direction is the axial extension direction of the first filter element 21 or the second filter element 22, and the longitudinal parallel direction is the diameter extension direction of the first filter element 21 or the second filter element 22.

[0065] Using the filter element mounting bracket 23 as its assembly base, the first water channel plate 30 and the booster pump 60 are both connected to the filter element mounting bracket 23. Assembly is orderly and convenient, and they can be integrated into a whole using methods such as snap-fit, threaded connection, and interlocking, ensuring the reliability of connections between the various components within the equipment. Furthermore, by placing the first water channel plate 30 and the booster pump 60 on the same side of the filter element mounting bracket 23, with the first water channel plate 30 and the booster pump 60 arranged side-by-side along the longitudinal direction of the equipment in the horizontal direction of the filter element mounting bracket 23, compared to the booster pump 60 being horizontally placed with the filter assembly 20 and arranged vertically side-by-side, or the booster pump 60 being horizontally placed with the filter assembly 20, this arrangement is more efficient. Furthermore, the vertical arrangement not only makes reasonable use of the longitudinal assembly space near the filter element mounting bracket 23, but also ensures that the height occupied by the filter element mounting bracket 23, the first water circuit plate 30, and the booster pump 60 after assembly is as small as possible. Therefore, without increasing the length of the original water purification equipment, the overall height of the original water purification equipment can be reliably reduced by 30mm to 50mm, which is about 15% of the original height. It also enables a compact design among the filter element mounting bracket 23, the first water circuit plate 30, and the booster pump 60, thereby reliably reducing the overall height and volume of the equipment.

[0066] In the technical solution of this invention, the filter assembly 20 is horizontally placed inside the housing 10. The filter assembly 20 includes a filter element body and a filter element mounting bracket 23. The filter element body includes a first filter element 21 and a second filter element 22. The filter element mounting bracket 23 has a first mounting cavity 2311 and a second mounting cavity 2321 arranged longitudinally side-by-side. Both the first mounting cavity 2311 and the second mounting cavity 2321 extend laterally. The first filter element 21 is mounted in the first mounting cavity 2311, and the second filter element 22 is mounted in the second mounting cavity 2321. 1; The booster pump 60 and the first water circuit plate 30 are arranged longitudinally side by side and located in the horizontal direction of the filter element mounting bracket 23. This not only makes reasonable use of the longitudinal assembly space near the filter element mounting bracket 23, but also ensures that the height occupied by the filter element mounting bracket 23, the first water circuit plate 30 and the booster pump 60 after assembly is as small as possible. It also achieves a compact design among the filter element mounting bracket 23, the first water circuit plate 30 and the booster pump 60, thereby reliably reducing the overall height of the equipment and reducing the overall volume of the equipment.

[0067] Reference Figures 2 to 5In one embodiment, the first water circuit plate 30 is provided with multiple non-interfering water flow channels. Two opposing surfaces of the first water circuit plate 30 are provided with interfaces connecting each of the water flow channels. The interfaces are connected to water circuit components. The water circuit components include at least an inlet valve 71, a wastewater valve 72, a check valve 73, and a water pressure switch 74. It can be understood that each interface is located on two opposing surfaces of the first water circuit plate 30, with one surface facing the filter element mounting bracket 23 and the other surface facing away from the filter element mounting bracket 23. At this time, the corresponding inlet valve 71, wastewater valve 72, check valve 73, and water pressure switch 74 are distributed on opposite sides of the first water circuit plate 30 according to their specific connection relationships. By making reasonable use of the assembly gap between the first water circuit plate 30 and the filter element mounting bracket 23, as well as the assembly gap between the first water circuit plate 30 and the housing 10, the space near the first water circuit plate 30 is maximized while ensuring the connection between the water circuit components and the water flow channels, thus achieving a high degree of integration between the first water circuit plate 30 and the water circuit components and reducing the overall volume of the equipment.

[0068] The first water channel plate 30 can be formed by injection molding; all water flow channels are concentrated in the first water channel plate 30. In the longitudinal direction, the projection of each water flow channel can be set to coincide with the booster pump 60, thereby improving the integration of each water flow channel, reducing the volume of the first water channel plate 30, and reducing the depth of the equipment in its vertical direction, which is perpendicular to both the longitudinal and transverse directions.

[0069] Based on the specific dimensions of the inlet valve 71, wastewater valve 72, check valve 73, and water pressure switch 74, as well as the dimensions of the assembly gaps within the equipment, the assembly positions of each component on the first water circuit board 30 are rationally planned. Specifically, for example... Figures 5 to 6 , Figure 9 As shown, in one embodiment, the inlet valve 71 and the wastewater valve 72 are located on the same side of the first water circuit plate 30 and are disposed away from the filter element mounting bracket 23. The one-way valve 73 and the water pressure switch 74 are located on the same side of the first water circuit plate 30 and are disposed facing the filter element mounting bracket 23.

[0070] Thus, due to the compact arrangement of the first water circuit plate 30 and the filter element mounting bracket 23, the assembly gap between the first water circuit plate 30 and the filter assembly 20 is limited. The one-way valve 73 and the water pressure switch 74 can be placed on the same side and located between the first water circuit plate 30 and the filter element mounting bracket 23. Since the inlet valve 71 and the wastewater valve 72 occupy approximately the same space in the horizontal direction of the equipment, the inlet valve 71 and the wastewater valve 72 can be placed on the same side. This achieves a compact layout of the filter assembly 20, water circuit components and the first water circuit plate 30, thereby reducing the overall width of the equipment to a certain extent.

[0071] Reference Figures 6 to 9In one embodiment, each of the water flow channels includes a tap water flow channel 311, a concentrated water flow channel 312, a drinking water flow channel 313, and a domestic water flow channel 314; the tap water flow channel 311 is connected to the tap water inlet of the first filter element 21; the domestic water flow channel 314 is connected to the filtered water outlet of the first filter element 21, the booster pump 60, the second filter element 22, and the pure water inlet of the first filter element 21; the drinking water flow channel 313 is connected to the pure water outlet of the first filter element 21; and the concentrated water flow channel 312 is connected to the wastewater outlet of the second filter element 22.

[0072] Understandably, the tap water in the tap water channel 311 enters the pre-filter of the first filter element 21 through the tap water inlet. The pre-filter performs initial filtration of the tap water. The resulting initially filtered water flows out through the filtered water outlet of the first filter element 21 and flows sequentially through the domestic water channel 314, the booster pump 60, and the second filter element 22. The booster pump 60 pressurizes the initially filtered water so that the water pressure at the front end of the second filter element 22 meets the filtration requirements, thereby obtaining secondary filtered water and wastewater. The secondary filtered water can enter the post-filter of the first filter element 21 through the pure water inlet. The post-filter filters the secondary filtered water again. The resulting drinking water flows out through the pure water outlet of the first filter element 21 and flows to and is stored in the drinking water channel 313. The resulting wastewater flows out through the wastewater outlet and flows to the concentrated water channel 312.

[0073] In addition, the tap water channel 311 is provided with a tap water inlet 3111, which is connected to an external water supply device. The concentrated water channel 312 is provided with a wastewater discharge outlet 3121, which is used to discharge the generated concentrated water. The drinking water channel 313 is provided with a drinking water discharge outlet 3131, which is used to discharge the generated drinking water. The domestic water channel 314 is provided with a domestic water discharge outlet 3141, which is used to discharge the primary filtered water, thus facilitating the use of the primary filtered water as cleaning water. The housing 10 is provided with an installation port for the tap water inlet 3111, wastewater discharge outlet 3121, drinking water discharge outlet 3131 and domestic water discharge outlet 3141 to be exposed.

[0074] Optionally, in one embodiment, the inner diameter of the domestic water flow channel 314 is d, where d ≥ 6 mm. It is understood that when d is less than 6 mm, taking d as an example of 5.5 mm, theoretical analysis and experimental testing show that the flow rate at an inner diameter of 5.5 mm will decrease by 0.2 L / min compared to the flow rate at an inner diameter of 6 mm. This affects the flow of the primary filtered water toward the second filter element 22, and consequently affects the filtration effect of the second filter element 22 on the primary filtered water. Of course, to avoid the first water circuit board 30 being too large, the inner diameter d ≤ 9 mm can be set to achieve miniaturization of the first water circuit board 30 and improve the size of the equipment. Therefore, the minimum inner diameter of the domestic water flow channel 314 is set to 6 mm to facilitate control of the flow rate of the primary filtered water in the domestic water flow channel 314, thereby ensuring reliable flow of the primary filtered water toward the second filter element 22, reducing the resistance of the reverse osmosis filter element to the primary filtered water, and improving the water output performance of the equipment.

[0075] Specifically, the inner diameter of the domestic water flow channel 314 can be 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, etc.

[0076] Combined with reference Figures 6 to 8 In one embodiment, the concentrated water channel 312, the drinking water channel 313, and the domestic water channel 314 are all provided with blocking ribs 32. The blocking ribs 32 are used to divide the water channel into two non-interfering sub-channels. It can be understood that by using the blocking ribs 32 to divide the same water channel into multiple independent sub-channels, the number of water channels on the first water channel plate 30 is increased without changing the volume of the first water channel plate 30. At the same time, the water path on the first water channel plate 30 is simplified, which is conducive to improving the structural integration and functional integration of the first water channel plate 30 and simplifying the water path between the first water channel plate 30 and the filter assembly 20.

[0077] Furthermore, the concentrated water channel 312 is equipped with the wastewater valve 72 to control the opening and closing of the two sub-channels on the concentrated water channel 312; the drinking water channel 313 is equipped with the one-way valve 73 to control the opening and closing of the two sub-channels on the drinking water channel 313; the domestic water channel 314 is equipped with the inlet valve 71 to control the opening and closing of the two sub-channels on the domestic water channel 314; and, in conjunction with the position of the blocking rib 32 on the water channel, the wastewater valve 72, the one-way valve 73, and the inlet valve 71 can cross the corresponding blocking rib 32, and realize the conduction and isolation between the corresponding two sub-channels by connecting or disconnecting the control, thereby realizing the opening and closing control of the water circuit on the same water channel, greatly reducing the volume of the first water circuit plate 3030, and simplifying the connection between the water circuit components and the first water circuit plate 30.

[0078] like Figure 8 As shown, the concentrated water channel 312 is provided with a wastewater valve mounting position 3122, the drinking water channel 313 is provided with a one-way valve mounting position 3132, and the domestic water channel 314 is provided with an inlet valve mounting position 3144. Taking the wastewater valve mounting position 3122 as an example, the wastewater valve mounting position 3122 is provided with two wastewater through holes that can connect the two sub-channels on the concentrated water channel 312, as well as a fixing seat for fixing the wastewater valve 72, so that the wastewater valve 72 can control the conduction and isolation of the two wastewater through holes. In addition, it can be connected to the fixing seat by bolts or other fasteners to ensure the stable assembly between the wastewater valve 72 and the first water circuit plate 30. In addition, the drinking water flow channel 313 is also equipped with a water pressure switch mounting position 3133 and a TDS water quality probe mounting position. The water pressure switch 74 is installed in the water pressure switch mounting position 3133, which can change the opening and closing of the one-way valve 73 according to the pressure change in the drinking water flow channel 313. The TDS water quality probe is installed in the TDS water quality probe mounting position, which can verify the purification effect of the equipment according to the detected drinking water TDS value. The TDS water quality probe can be located on the same side as the wastewater valve 72 and the inlet valve 71, and is located between the wastewater valve 72 and the inlet valve 71. The domestic water flow channel 314 is also equipped with a booster pump connection position 3145.

[0079] On the first water circuit board 30, corresponding wastewater valve installation position 3122, check valve installation position 3132 and inlet valve installation position 3144 can be equipped with recognizable icons, which can be configured as text or water flow direction arrows.

[0080] Based on the connection principle between each water flow channel and the first filter element 21, the second filter element 22, and the booster pump 60, the domestic water flow channel 314 is connected in series between the first filter element 21 and the booster pump 60. The booster pump 60 and the first water circuit board 30 are arranged longitudinally side-by-side in the horizontal direction of the filter element mounting bracket 23. Due to this layout, the arrangement of the connecting pipe 51 connecting the first water circuit board 30, the first filter element 21, and the booster pump 60 is easily affected, thus impacting the water circuit performance. Therefore, if... Figure 2 and Figure 8 As shown, in one embodiment, the domestic water flow channel 314 includes a first flow channel 3142 and a second flow channel 3143 connected by a bend. The first flow channel 3142 is connected to the first filter element 21, and the second flow channel 3143 is connected to the booster pump 60. This facilitates the spatial water flow connection of the first water circuit board 30, reduces the use of joints and connecting pipes 51 such as PE pipes, and at the same time, while ensuring water flow performance, it helps to make the spatial arrangement of pipes more reasonable, orderly and simple.

[0081] Specifically, the first water circuit plate 30 includes a main water circuit plate and a transition water circuit plate. The transition water circuit plate is connected to the side of the main water circuit plate away from the filter element mounting bracket 23, thus making reasonable use of the assembly space between the main water circuit plate and the housing 10. The main water circuit plate has a second flow channel 3143, and the transition water circuit plate has a first flow channel 3142. The first flow channel 3142 and the second flow channel 3143 are bent and connected, which can further reduce the use of complex pipes and joints. While ensuring water circuit performance, it helps to make the spatial arrangement of pipes more reasonable, regular and simple. There are reinforcing ribs connecting the transition water circuit plate and the main water circuit plate to ensure the reliability of the connection between the main water circuit plate and the transition water circuit plate.

[0082] Furthermore, the first flow channel 3142 includes a first sub-flow channel and a second sub-flow channel connected by bending. The first sub-flow channel is connected to the first filter element 21, and the second sub-flow channel is connected to the first flow channel 3142. At this time, the first flow channel 3142 is L-shaped, and the first sub-flow channel extends vertically, which facilitates water circuit connection and simplifies the pipeline between the main water circuit board and the filter assembly 20. At the same time, it reduces the increase of leakage points caused by the use of complex pipelines and joints, effectively optimizes the manufacturability of the equipment, reduces leakage points, and improves the quality and reliability of the water purification equipment.

[0083] Furthermore, the domestic water flow channel also includes a third flow channel, which connects the first flow channel 3142 and the second flow channel 3143. The third flow channel extends along the extension direction of the filter assembly 20, i.e., the extension direction of the filter assembly 20 is horizontal. The third flow channel 3144 is used to discharge domestic water filtered by the first filter element 21, and to achieve waterway communication between the first flow channel 3142 and the second flow channel 3143. The first flow channel 3142 can be connected below the third flow channel via a second sub-flow channel, making reasonable use of the space below the third flow channel and reserving space above the third flow channel, thereby facilitating reliable integration of the water circuit components onto the first water circuit plate 30. The third flow channel has a domestic water discharge port 3141 for discharging the initially filtered water, thus facilitating the use of the initially filtered water as cleaning water.

[0084] Specifically, in one embodiment, the tap water channel 311, the concentrated water channel 312, the drinking water channel 313, and the second channel 3143 are arranged side by side along the vertical direction, and the first channel 3142 extends in the opposite direction along the vertical direction and is located below the tap water channel 311, the concentrated water channel 312, the drinking water channel 313, and the second channel 3143; the vertical direction is perpendicular to the horizontal direction and the longitudinal direction, respectively. The tap water channel 311, the concentrated water channel 312, the drinking water channel 313, and the second channel 3143 are formed on the main water circuit plate, which helps to reduce the space occupied by the main water circuit plate, thereby reducing the volume of the water purification equipment.

[0085] Since each water flow channel needs to be connected to the outside, the tap water flow channel 311, the concentrated water flow channel 312, and the drinking water flow channel 313 are all provided with external flow channels extending along the extension direction of the filter assembly 20. At this time, the third flow channel and the external flow channel are arranged vertically side by side and are located above the first flow channel 3142. The space below the third flow channel and the external flow channel is used to arrange the water circuit plate to ensure that the main water circuit plate and the filter assembly 20 are connected and to facilitate the pipeline layout between the main water circuit plate and the filter assembly 20.

[0086] Because the second flow channel 3143 is arranged side by side with the tap water flow channel 311, the concentrated water flow channel 312, and the drinking water flow channel 313, and the drinking water flow channel 313 is located between the second flow channel 3143 and the concentrated water flow channel 312, when the wastewater valve 72 is set on the concentrated water flow channel 312 and the inlet valve 71 is set on the second flow channel 3143, the wastewater valve 72 and the inlet valve 71 can make reasonable use of the space near the drinking water flow channel 313. In addition, by staggering the wastewater valve 72 and the inlet valve 71, a compact layout of the wastewater valve 72 and the inlet valve 71 can be achieved, thereby reducing the overall volume of the first water circuit board 30 and the water circuit components.

[0087] Reference Figure 5 and Figure 9 In one embodiment, the water circuit component further includes a leakage protection device 75. The leakage protection device 75 is installed on the first water circuit plate 30 and connected in series between the tap water channel 311 and the first filter element 21. By installing the leakage protection device 75 within the device, the opening and closing of the water inlet is controlled, ensuring that the leakage protection device 75 can promptly block the water source and reduce losses in the event of a leak. The leakage protection device 75 is positioned at a lower location within the device. In this case, a connection for installing the leakage protection device 75 can be provided at the bottom of the first water circuit plate 30. The leakage protection device 75 can be assembled with the first water circuit plate 30 via a threaded connection.

[0088] Specifically, the first water circuit plate 30 has a clearance position 34 on the side facing the filter element mounting bracket 23. The clearance position 34 is used to avoid the leakage protection device 75. In this way, the assembly gap between the first water circuit plate 30 and the leakage protection device 75 can be reduced. As a result, when the leakage protection device 75 is set between the filter assembly 20 and the first water circuit plate 30, the required assembly space is small, further reducing the overall volume of the equipment.

[0089] Reference Figure 2In one embodiment, the filter element mounting bracket 23 is connected to the housing 10 and includes a first bracket 231 and a second bracket 232. The first bracket 231 is connected to the booster pump 60, and the second bracket 232 is connected to the first water circuit board 30. It is understood that the first bracket 231 and the second bracket 232 are arranged longitudinally side-by-side, integrating the first bracket 231 and the booster pump 60, and the second bracket 232 and the first water circuit board 30 into a single unit, thereby improving the efficiency of the first bracket 231 and the booster pump 60, and the second bracket 232 and the first water circuit board 30. The tight connection between each pair of water circuit boards 30 reduces the space occupied. Furthermore, the connection between the first bracket 231 and the booster pump 60 can be achieved using adapters, fasteners, etc., to avoid vibration transmission caused by the direct connection between the booster pump and the housing, thereby reducing equipment noise. The second bracket 232 and the first water circuit board 30 can be assembled using plug-in or snap-fit ​​methods to ensure the stability of the connection between the first bracket 231 and the booster pump 60, and between the second bracket 232 and the first water circuit board 30, as well as the ease of assembly.

[0090] Specifically, in one embodiment, the first bracket 231 is located above the second bracket 232 and has a first mounting cavity 2311, while the second bracket 232 has a second mounting cavity 2321. In this case, the first filter element 21 is located above the second filter element 22, the booster pump 60 is located above the first water circuit board 30, and the pump body of the booster pump 60 is positioned close to the first water circuit board 30. The motor of the booster pump 60 is connected to the first bracket 231. However, in other embodiments, the first bracket 231 is located below the second bracket 232.

[0091] Since the filter element mounting bracket 23 is connected to the housing 10, and the housing 10 includes a top cover, a base 11 and a side panel disposed between the top cover and the base 11, it can be understood that the first bracket 231 can be connected to the top cover and can also be connected to the side panel, and the second bracket 232 can be connected to the base 11 and can also be connected to the side panel, further improving the connection stability between the housing 10 and the filter assembly 20.

[0092] Combined with reference Figure 2 and Figure 4In one embodiment, the first bracket 231 includes a first limiting wing 233 connected to the housing 10. Two first limiting wings 233 are provided and are respectively disposed on opposite sides of the booster pump 60. The first limiting wings 233 can be connected to the housing 10 by means of fastening or embedding to improve the assembly stability of the filter element mounting bracket 23. The booster pump 60 can be spaced apart from the first limiting wings 233 to ensure the connection between the booster pump 60 and the first bracket 231. At the same time, it is convenient for the booster pump 60 to accurately locate the installation position on the first bracket 231, which speeds up the assembly. After the booster pump 60 is assembled to the first bracket 231, the setting of the first limiting wings 233 can reduce the risk of damage to the booster pump 60 due to external forces, thus playing a protective role. Furthermore, the first bracket 231, the first limiting wings 233 and the housing 10 surround the booster pump 60, which helps to form a sound insulation cavity, thereby reducing the noise of the equipment.

[0093] The second bracket 232 includes a second limiting wing 234 connected to the housing 10. Two second limiting wings 234 are provided and are respectively provided on opposite sides of the first water channel plate 30. The second limiting wings 234 can be connected to the housing 10 by means of fastening, embedding or other methods to further improve the assembly stability of the filter element mounting bracket 23. The first water channel plate 30 can be provided at intervals with the second limiting wings 234, or the second limiting wings 234 can form a clearance notch to avoid part of the structure of the first water channel plate 30, ensuring the convenience of connection between the first water channel plate 30 and the second bracket 232. At the same time, it is convenient for the first water channel plate 30 to find the installation position on the second bracket 232, speeding up the assembly speed. Furthermore, after the first water channel plate 30 is assembled to the second bracket 232, the setting of the second limiting wings 234 can reduce the risk of damage to the first water channel plate 30 due to external forces, thus playing a protective role. Of course, in other embodiments, only one first limiting wing 233 and / or second limiting wing 234 may be provided on the same side of the device, or multiple first limiting wings 233 and / or second limiting wings 234 may be provided at intervals on the same side of the device.

[0094] Furthermore, the first bracket 231 and the second bracket 232 are integrally formed, such as... Figure 2 As shown, a connecting plate connects the first bracket 231 and the second bracket 232, allowing them to be integrated into a single unit. This further enhances the structural strength and rigidity of the filter element mounting bracket 23, ensuring its overall stability and strengthening its load-bearing capacity for the first filter element 21 and the second filter element 22. Furthermore, the integrated design of the first bracket 231 and the second bracket 232 reduces the number of parts in the equipment.

[0095] Reference Figures 2 to 5In one embodiment, the device further includes a second water channel plate 40, which is connected to the filter element mounting bracket 23 and serves to connect the first water channel plate 30 and the first filter element 21, the second filter element 22 and the booster pump 60, and the first filter element 21 and the second filter element 22. In this case, the second water channel plate 40 serves as a transition water channel plate between the filter element mounting bracket 23 and the first water channel plate 30. It can be set close to the end caps of the first filter element 21 and the second filter element 22 and is fixedly connected to the filter element mounting bracket 23. Furthermore, the first water channel plate 30 can be spaced apart from the second water channel plate 40 and located at the rear end of the filter element mounting bracket 23. Tap water will flow from the first water channel plate 30 to the second water channel plate 40, and the connection between the second water channel plate 40 and the end caps on the first filter element 21 and the second filter element 22 can meet the diverse needs of tap water filtration.

[0096] Specifically, due to the sealing requirements of the filter element's end cap and cylinder, and factors such as the multiple flow paths within the end cap, the radial dimension of the end cap is larger than that of the cylinder. Therefore, when the first support 231 and the second support 232 are arranged side by side, an assembly gap is always maintained between them. Figure 2 As shown, the second water channel plate 40 is disposed between the first bracket 231 and the second bracket 232, making reasonable use of the assembly gap between the first bracket 231 and the second bracket 232 to further achieve a compact design and reduce the overall height of the equipment.

[0097] Because the first water channel plate 30 and the second water channel plate 40 are spaced apart, in one embodiment, the first water channel plate 30 and the second water channel plate 40 are connected by a connecting pipe 51. In this case, the connecting surfaces of the first water channel plate 30 and the second water channel plate 40 face each other, which improves the ease of installation of the connecting pipe 51. Furthermore, the connecting pipe 51 can be a straight pipe, ensuring a smooth transition and reducing changes in the extension direction of the connecting pipe 51. This effectively avoids difficulties in pipe installation and the potential quality risks caused by it. It also reduces the flow resistance of water within the connecting pipe 51, improves the smoothness of water flow and the water output performance of the equipment, and reduces the operating noise of the equipment, thereby improving the reliability of the equipment. The connecting pipe 51 can be a PE pipe.

[0098] In accordance with the specific structure of the domestic water flow channel 314 of the first water channel plate 30, the domestic water flow channel 314 is L-shaped, and the inlet connecting to the first filter element 21 is located on the side of the first water channel plate 30, such as... Figure 2 As shown, the connecting pipe 51 is L-shaped, which ensures a smooth transition and fewer turning points. The connecting pipes 51 corresponding to other water flow channels on the first water channel plate 30 are not shown in the figure.

[0099] Reference Figures 6 to 9In one embodiment, the first water channel plate 30 is vertically connected to a mounting wing 35, the vertical direction being perpendicular to both the transverse and longitudinal directions. It is understood that the first water channel plate 30 and the mounting wing 35 are integrally formed, wherein at least one of the first water channel plate 30 and the mounting wing 35 is connected to a filter element mounting bracket 23, thus achieving the connection between the first water channel plate 30 and the filter element mounting bracket 23. Figure 9 As shown, the first water channel plate 30 has mounting wings 35 on both opposite sides. One mounting wing 35 has a first connecting structure, and the side of the first water channel plate 30 near the other mounting wing 35 also has a first connecting structure. At this time, the filter element mounting bracket 23 has a second connecting structure that cooperates with the first connecting structure. The first connecting structure and the second connecting structure can be connected by fasteners such as bolts. Of course, in other embodiments, both mounting wings 35 have a first connecting structure.

[0100] The first connecting structure can be configured as a mounting through hole, and the second connecting structure can be configured as a threaded mounting post, so that the two can be connected by fasteners such as bolts; of course, in other embodiments, the second connecting structure can also be configured as a fastener that mates with the mounting through hole.

[0101] Specifically, in one embodiment, the mounting wing 35 includes a first segment 351 and a second segment 352 that are bent and connected. The first segment 351 is connected between the first water channel plate 30 and the second segment 352. The free end of the second segment 352 extends toward the filter element mounting bracket 23. Specifically, one end of the first segment 351 is connected to the first water channel plate 30, and the other end is set away from the water flow channel of the first water channel plate 30, so that the first segment 351 has a large installation area, which facilitates the mounting wing 35 to connect to the filter element mounting bracket 23 through the first segment 351. At the same time, it reduces the interference between the filter element mounting bracket 23 and the water flow channel and connecting pipe 51 on the first water channel plate 30. Since the second segment 352 is bent and connected to the first segment 351, and its free end extends toward the filter element mounting bracket 23, the mounting wing 35 has high strength. In addition, the second segment 352 can be spaced apart from the housing 10 or abut against the housing 10, which helps to improve the collision protection performance of the first water channel plate 30.

[0102] To ensure the connection stability of the connecting pipe 51, in one embodiment, a water pipe limiting structure is provided on the mounting wing 35. The water pipe limiting structure is used to fix the connecting pipe 51. By setting the water pipe limiting structure, the connection area between the connecting pipe 51 and the mounting wing 35 is increased, further improving the connection stability between the mounting wing 35 and the connecting pipe 51, thereby ensuring the stability of the connecting pipe 51 between the first water circuit plate 30 and the second water circuit plate 40, and ensuring the water circuit performance.

[0103] like Figure 2 , Figure 4 and Figure 6 In one embodiment, the water pipe limiting structure is configured as a limiting slot 3511 formed on the mounting wing 35. The connecting pipe 51 is inserted into the limiting slot 3511, increasing the connection area between the connecting pipe 51 and the mounting wing 35. Further, a pipe support 52 is provided between the connecting pipe 51 and the limiting slot 3511. The pipe support 52 is fitted onto the bend of the connecting pipe 51 to ensure the bending performance of the connecting pipe 51 and, simultaneously, to ensure the reliability of the connection between the connecting pipe 51 and the mounting wing 35. However, in other embodiments, the water pipe limiting structure can be configured as the top surface of the mounting wing 35, directly supporting the connecting pipe 51 and thus ensuring its stability; it can also be configured as a mounting base connected to the periphery of the mounting wing 35.

[0104] Reference Figures 10 to 11 In one embodiment, the first water channel plate 30 has a support 33 on the side opposite to the filter element mounting bracket 23. The support 33 has a first insertion position 331. The housing 10 includes a base 11, which has a second insertion position 111 that mates with the first insertion position 331. The insertion and engagement between the first insertion position 331 and the second insertion position 111 compresses the first water channel plate 30 and the base 11, enhancing the assembly stability between them. The support 33 can also raise the overall assembly position of the first water channel plate 30, facilitating a larger assembly space between the bottom of the first water channel plate 30 and the base 11, which is beneficial for the installation of the leakage protection device 75 on the first water channel plate 30.

[0105] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
