Description

Technical Field

[0001] This utility model relates to the field of water purification technology, and in particular to a horizontally placed filter cartridge assembly and a water purification device. Background Technology

[0002] With societal development, people have increasingly higher demands for water quality. Currently, water purification equipment refers to water treatment equipment that performs deep filtration and purification of water according to usage requirements. It can remove impurities from water (such as floating matter, heavy metals, bacteria, viruses, residual chlorine, sediment, rust, microorganisms, etc.) and improve water quality. Water purification equipment is widely used in homes, offices, shopping malls, factories, and other places.

[0003] Currently, water purifiers are typically installed under kitchen cabinets, and the filter cartridges are usually placed vertically. Replacing the filter cartridges requires moving the entire water purifier, making the process difficult. Placing the filter cartridges horizontally makes replacement easier; however, the lower outlet of a horizontally placed filter cartridge makes it easier for air to trap in the space above the outlet. This can damage the water purifier and may trap air in the middle of the filter cartridge, requiring longer periods or higher water pressure to expel the air, resulting in delayed water output and a poor user experience.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] Although the present invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0032] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0033] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0034] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the structure of a horizontally placed filter element assembly 10 provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of the water flow direction of a horizontally placed filter element assembly 10 provided in this embodiment of the present invention. Figure 3 This is a schematic diagram of the structure of an exhaust end cap 13 provided in an embodiment of the present utility model. The horizontally placed filter element assembly 10 may include: a filter shell 11, a filter element 12 and an exhaust end cap 13.

[0035] One end of the filter housing 11 may have an inlet k1. The filter housing 11 may also have a clean water outlet k2 and a wastewater outlet k3 located at the same end as the inlet k1. The inlet k1, the clean water outlet k2 and the wastewater outlet k3 may be arranged in sequence along the direction away from the ground.

[0036] The filter element 12 is located inside the filter housing 11, forming an inlet chamber q1 with the filter housing 11. The inlet chamber q1 is connected to the inlet k1. The filter element 12 can be used to filter raw water. The filter element 12 may include a reverse osmosis (RO) filter element. The filter element 12 includes a reverse osmosis membrane structure 121 and a water collection pipe 122. The water collection pipe 122 may be located inside the reverse osmosis membrane structure 121. The inside of the water collection pipe 122 has a purified water chamber q2, and the water collection pipe 122 has multiple water passage holes that can communicate with the purified water chamber q2. The purified water chamber q2 can also communicate with the purified water outlet k2. The filtered water from the reverse osmosis membrane structure 121 can enter the purified water chamber q2 through the multiple water passage holes and then flow out from the purified water outlet k2 for user use.

[0037] The exhaust end cap 13 is installed on the end of the filter element 12 opposite to the inlet k1. The exhaust end cap 13 has n through holes k4 evenly distributed circumferentially along its circumference. Each of the n through holes k4 can connect the inlet chamber q1 and the inlet end of the filter element 12. n is an integer greater than or equal to 8, and the sum of the cross-sectional areas of the n through holes k4 is less than or equal to the cross-sectional area of ​​the inlet k1. The cross-sectional area can refer to the effective flow area of ​​the through holes or the inlet.

[0038] When raw water flows from the inlet k1 of the filter housing 11 into the inlet chamber q1 between the filter housing 11 and the filter element 12, the raw water gradually fills the inlet chamber q1. As the water level in the inlet chamber q1 rises, air in the inlet chamber q1 flows through multiple through holes k4 from the n through holes k4 to the inlet end of the exhaust end cover 13 and the filter element 12, and then passes through the filter element 12 and is discharged from the wastewater outlet k3, thus venting the inlet chamber q1. After the raw water fills the inlet chamber q1, the water flow can enter the inlet end of the filter element 12 through the n through holes k4. The filter element 12 begins to pass water and produces two parts of water, namely clean water and wastewater. At this time, the clean water enters the clean water chamber q2 through the water passage of the water collection pipe 122 and finally flows out from the clean water outlet k2 for user use; the wastewater is discharged through the wastewater outlet k3.

[0039] It is understandable that during the venting process of the horizontally placed filter element assembly 10, raw water flows from some of the lower-positioned through holes k4 into the space between the vent end cap 13 and the water inlet end of the filter element 12, and enters the filter element 12 from the water inlet end. Since the sum of the cross-sectional areas of the n through holes k4 is less than or equal to the cross-sectional area of ​​the water inlet k1, and the water flow velocity of the water inlet k1 is relatively high (for example, the water flow velocity of the water inlet k1 can be 1.5 liters per minute), while the area of ​​each through hole k4 is relatively small, the raw water flows from... When the water enters the space between the exhaust end cover 13 and the filter element 12 through the through hole k4, the flow rate is relatively slow. After entering the space between the exhaust end cover 13 and the filter element 12, the water will gradually enter the filter element 12, which further slows down the rise rate of the water level in the filter element 12. Therefore, when the water inlet chamber q1 is full of water, the water level in the filter element 12 does not exceed the wastewater outlet k3, thereby avoiding the situation where the wastewater outlet k3 is blocked during the exhaust process, and thus realizing the exhaust of the horizontal filter element assembly 10.

[0040] Thus, during the water intake process of the horizontal filter element assembly 10, air can be vented from the water inlet chamber q1 through the multiple through holes k4 on the vent end cap 13, avoiding the problem of air trapping in the horizontal filter element assembly 10, thereby improving the utilization rate of the horizontal filter element assembly 10 and extending its service life. Furthermore, since the eight through holes k4 are evenly distributed along the circumference of the vent end cap 13, when the horizontal filter element assembly 10 is installed in the water purifier, at least one of the eight through holes k4 is located at or near the top, allowing for different water levels inside and outside the vent end cap 13, thus achieving the venting effect. This eliminates the need to specifically consider the placement direction of the horizontal filter element assembly 10, reducing the installation difficulty of the horizontal filter element assembly 10.

[0041] In addition, when the horizontal filter element assembly 10 is in the off state, the inlet chamber can remain full of raw water. In this way, when the user takes water next time, there is no need to refill the inlet chamber with water, thereby improving the water output delay of the horizontal filter element assembly 10.

[0042] In summary, this utility model embodiment provides a horizontally positioned filter element assembly 10 including a filter housing 11, a filter element 12, and an exhaust end cap 13. The exhaust end cap 13 is installed at the end of the filter element 12 opposite to the water inlet k1. The exhaust end cap 13 has n through holes k4 evenly distributed along its circumference. Each of the n through holes k4 can be used to connect the water inlet chamber q1 and the water inlet end of the filter element 12. n is an integer greater than or equal to 8, and the sum of the cross-sectional areas of the n through holes k4 is less than or equal to the cross-sectional area of ​​the water inlet k1. During the water intake process of the horizontally positioned filter element assembly 10, the water inlet chamber q1 can be vented through the multiple through holes k4 on the exhaust end cap 13, avoiding the problem of air accumulation in the horizontally positioned filter element assembly 10, thereby improving the utilization rate of the horizontally positioned filter element assembly 10 and extending its service life. Furthermore, since at least eight through holes k4 can be evenly distributed along the circumference of the exhaust end cap 13, there is no need to consider the placement direction of the horizontal filter element assembly 10 during installation, which can reduce the installation difficulty of the horizontal filter element assembly 10. In addition, when the horizontal filter element assembly 10 is in the off state, the inlet chamber can remain full of raw water, which can improve the water output delay of the horizontal filter element assembly 10.

[0043] In one alternative embodiment, the cross-sectional areas of the n through holes k4 are all equal, which can make the water flow when the raw water enters the filter element 12 more stable.

[0044] In one alternative embodiment, the sum of the cross-sectional areas of the n through holes k4 is equal to the cross-sectional area of ​​the inlet k1. This ensures water pressure balance at the inlet end of the horizontally positioned filter element assembly 10, inside the horizontally positioned filter element assembly 10, and at the outlet end of the horizontally positioned filter element assembly 10.

[0045] In one alternative implementation, please refer to Figure 2 and Figure 3 The exhaust end cover 13 includes an end panel 131 and an annular side plate 132. One end of the annular side plate 132 is fixedly connected to the end panel 131, and the other end of the annular side plate 132 is sleeved on the filter element 12. n through holes k4 are all provided on the annular side plate 132. The end panel 131 and the annular side plate 132 can be bonded together or be an integral structure. The exhaust end cover 13 may also include a fixing shaft, which can be inserted into the filter element 12.

[0046] In an alternative embodiment, all n through holes k4 are located at one end of the annular side plate 132 near the end panel 131, which can prevent the through holes k4 from being blocked by the filter element 12 when the exhaust end cap 13 is fitted onto one end of the filter element 12.

[0047] In an optional embodiment, the exhaust end cap 13 may further include a plurality of reinforcing ribs 133, which are fixed to the side of the end panel 131 near the annular side plate 132, and the plurality of reinforcing ribs 133 are arranged circumferentially along the exhaust end cap 13; the side of the reinforcing ribs 133 facing away from the end panel 131 abuts against the filter element 12. The length direction of the reinforcing ribs 133 may be parallel to the radial direction of the exhaust end cap 13, and the plurality of reinforcing ribs 133 may provide support between the end panel 131 and the water inlet end of the filter element 12, thereby forming a water flow channel between the end panel 131 and the water inlet end of the filter element 12.

[0048] In one alternative implementation, please refer to Figure 4 , Figure 4 This is a cross-sectional structural diagram of an exhaust end cap 13 provided in an embodiment of the present invention. In the direction perpendicular to the surface of the end panel 131, the first height x1 of the reinforcing rib 133 is greater than or equal to the second height x2 of the through hole k4. The second height x2 of the through hole k4 refers to the shortest distance between the top of the through hole k4 away from the end panel 131 and the end panel 131. In this way, the through hole k4 can remain connected to the water flow channel.

[0049] In an optional embodiment, the horizontally positioned filter element assembly 10 may further include an annular sealing ring, which surrounds the joint between the exhaust end cap 13 and the filter element 12 and is fixedly connected to both the exhaust end cap 13 and the filter element 12. The annular sealing ring may include sealing tape to improve the connection stability between the exhaust end cap 13 and the filter element 12.

[0050] In one alternative embodiment, the shape of the through hole k4 may include a circle, an ellipse, a hexagon, or a rectangle. For example, the through hole k4 may be a circular through hole k4 with a diameter of 2 mm.

[0051] This utility model embodiment also provides a water purification device, which may include: a device housing and a horizontally placed filter element assembly installed in the device housing. The horizontally placed filter element assembly includes the horizontally placed filter element assembly in any of the above embodiments. The horizontally placed filter element assembly in the water purification device may include a filter shell, a filter element, and an exhaust end cap. The exhaust end cap is installed at the end of the filter element opposite to the water inlet. The exhaust end cap is provided with n through holes evenly distributed along the circumference of the exhaust end cap. Each of the n through holes can be used to connect the water inlet chamber and the water inlet end of the filter element. n is an integer greater than or equal to 8, and the sum of the cross-sectional areas of the n through holes is less than or equal to the cross-sectional area of ​​the water inlet. During the water intake process of the horizontally placed filter element assembly, the water inlet chamber can be vented through the multiple through holes on the exhaust end cap, avoiding the problem of air accumulation in the horizontally placed filter element assembly, thereby improving the utilization rate of the horizontally placed filter element assembly and extending its service life. Furthermore, since the eight through holes are evenly distributed along the circumference of the exhaust end cap, there is no need to consider the placement direction of the horizontal filter element assembly during installation, which reduces the installation difficulty. In addition, when the horizontal filter element assembly is in the off state, the inlet chamber can remain full of raw water, which can improve the water output delay of the horizontal filter element assembly.
