Description

Technical Field

[0001] This utility model relates to the field of water purification technology, specifically providing a filter element and a water storage device for a water storage device. Background Technology

[0002] As people's living standards improve, their demand for drinking water is also increasing. Water purifiers, water purifier-drinking machines, and other water purification equipment are gradually becoming essential drinking water facilities in people's daily lives.

[0003] Existing water purification equipment is usually equipped with a raw water tank for water storage. When supplying water, the raw water tank usually has a filter screen at the outlet to filter out larger particles of impurities and prevent them from entering the filter element of the water purification equipment.

[0004] Existing filter screens are generally made of stainless steel wire mesh as an insert through injection molding, or of stainless steel mesh sheets with elastic clips on silicone sleeves. However, both of these types of filter screens are prone to clogging by impurities, resulting in a poor user experience. Utility Model Content

[0005] The present invention aims to solve the above-mentioned technical problems to at least a certain extent, that is, to solve the problem that existing filters are easily clogged by impurities, resulting in a poor user experience.

[0006] In a first aspect, the present invention provides a filter element for a water storage device, the water storage device having a water storage chamber and a water outlet pipe, the water outlet pipe being connected to the water storage chamber so that water in the water storage chamber flows out through the water outlet pipe in a first direction, the filter element including a connected filter component and a mounting component, the mounting component being used to mount the filter component on the water outlet pipe, the filter component being capable of filtering water flowing out from the water storage chamber, wherein the filter surface of the filter component protrudes toward a second direction, the second direction being opposite to the first direction.

[0007] In the preferred embodiment of the filter element for the water storage device described above, the filter element is spherical, ellipsoidal, or conical; and / or, the filter element is a filter screen with multiple filter holes, the diameter of which gradually increases along the water flow direction.

[0008] In the preferred embodiment of the filter element for the water storage device described above, the mounting member can be connected to the inner wall of the outlet pipe to install the filter element on the inner side of the outlet pipe; and / or, the mounting member can be connected to the outer wall of the outlet pipe to install the filter element on the outer side of the outlet pipe.

[0009] In the preferred embodiment of the filter element for the water storage device described above, the mounting member includes a mounting ring and a mounting rib disposed on the mounting ring. When the outer wall of the water outlet pipe is adapted to the mounting ring, the mounting ring is connected to the outer wall of the water outlet pipe to install the filter element on the outside of the water outlet pipe; when the inner wall of the water outlet pipe is adapted to the mounting rib, the mounting rib is connected to the inner wall of the water outlet pipe to install the filter element on the inside of the water outlet pipe.

[0010] In the preferred embodiment of the filter element for the water storage device described above, the number of mounting ribs is at least two and they are distributed at intervals along the outer wall of the mounting ring, wherein the outer diameters of two adjacent mounting ribs are equal.

[0011] In the preferred embodiment of the filter element for the water storage device described above, the number of mounting ribs is at least two and they are distributed at intervals along the outer wall of the mounting ring, wherein: the outer diameter of the mounting rib gradually increases from the side closer to the filter member to the side farther away from the filter member; or, the outer diameter of the mounting rib gradually decreases from the side closer to the filter member to the side farther away from the filter member.

[0012] In the preferred embodiment of the filter element for the water storage device described above, the filter element further has a grip portion so that the user can remove the filter element from the water storage device by means of the grip portion; and / or, the filter element and the mounting member are fixedly connected or integrally formed.

[0013] In the preferred embodiment of the filter element for the water storage device described above, the gripping part is a lifting rib formed on the outer peripheral surface of the filter member.

[0014] In the preferred embodiment of the filter element for the water storage device described above, the lifting rib is annular; and / or, the side of the lifting rib near the mounting member is provided with an inclined surface, so that the user applies a lifting force toward a second direction to the inclined surface to remove the filter element from the water storage device.

[0015] In a second aspect, the present invention also provides a water storage device, the water storage device comprising the filter element for a water storage device described in any of the preceding claims.

[0016] When the above-mentioned preferred technical solution is adopted, by setting the filter element as a filter component and an installation component, the filter component can be installed on the water outlet pipe through the installation component. When the water in the water storage device flows out through the water outlet pipe, the water flowing out from the water storage chamber can be filtered by the filter component. By setting the filter surface of the filter component to bulge in the second direction, it is possible to prevent pollutants in the water from accumulating on the surface of the filter component, thereby avoiding the pollutants from clogging the filter component, extending the service life of the filter component, and greatly improving the user experience.

[0017] Furthermore, by setting the aperture of the filter holes to gradually increase along the water flow direction, on the one hand, when the water in the water storage chamber flows out through the outlet pipe, the cross-section of the filter hole near the inlet end is small and the water pressure is high, while the cross-section near the outlet end is large and the water pressure is low. This prevents impurities at the inlet end of the filter hole from being sucked to the outlet end, further reducing dirt passing through the filter screen and improving the filtration effect of the filter element. On the other hand, during the processing of the filter component, when the filter holes are formed, the mold needle can be made conical, thereby avoiding breakage of the mold needle, thus reducing processing difficulty and improving processing efficiency.

[0018] Furthermore, when the mounting component is compatible with the inner diameter of the outlet pipe, the filter component can be installed on the inner side of the outlet pipe. When the mounting component is compatible with the outer diameter of the outlet pipe, the filter component can be installed on the outer side of the outlet pipe. This allows the mounting component to be used with outlet pipes of different diameters, expanding the applicability of the filter element and further enhancing the user experience.

[0019] Furthermore, by setting the number of mounting ribs to at least two and ensuring that the outer diameters of two adjacent mounting ribs are equal, the installation stability and connection sealing of the filter element can be improved, thereby enhancing the filtration effect on the water flowing into the water storage device.

[0020] Furthermore, by setting the number of mounting ribs to at least two and gradually increasing the outer diameter of the mounting ribs from the side closer to the filter element to the side farther from the filter element, or gradually decreasing the outer diameter of the mounting ribs from the side closer to the filter element to the side farther from the filter element, each mounting rib can be adapted to water outlet pipes with different inner diameters, thereby making the filter element more widely applicable and further improving the user experience.

[0021] Furthermore, by providing a grip, the filter element can be easily removed from the water storage device, thereby reducing the difficulty of disassembling the installation structure and further improving the user experience.

[0022] Furthermore, the water storage device provided by this utility model, based on the aforementioned filter element for water storage devices, possesses the beneficial effects of the aforementioned filter element for water storage devices because it includes the aforementioned filter element for water storage devices. Compared with the water storage device before the improvement, the water storage device of this utility model has a better filtration effect when discharging water and is less prone to clogging, resulting in a better user experience.

[0037] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0038] It should be noted that in the description of this utility model, terms such as "upper," "lower," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] Based on the problem mentioned in the background art that existing raw water tank filters are prone to accumulating impurities, resulting in a poor user experience, this utility model provides a filter element for water storage devices.

[0041] Specifically, please refer to Figures 1 to 11 The water storage device 2 of this utility model has a water storage chamber 20 and a water outlet pipe 21. The water outlet pipe 21 is connected to the water storage chamber 20 so that the water in the water storage chamber 20 flows out in the first direction through the water outlet pipe 21. The filter element 1 includes a connected filter component 11 and a mounting component 12. The mounting component 12 is used to install the filter component 11 onto the water outlet pipe 21. The filter component 11 can filter the water flowing out from the water storage chamber 20. The filter surface of the filter component 11 protrudes in the second direction, which is opposite to the first direction.

[0042] With this configuration, when the water in the water storage device 2 flows out through the water outlet pipe 21, the water flowing out of the water storage chamber 20 can be filtered by the filter component 11. By setting the filter surface of the filter component 11 to protrude in the second direction, it is possible to prevent pollutants in the water from accumulating on the surface of the filter component 11, thereby avoiding the pollutants from clogging the filter component 11, extending the service life of the filter component 11, and greatly improving the user experience.

[0043] It should be noted that this utility model does not limit the specific type of water storage device 2 to which the filter element 1 is applicable. For example, the water storage device 2 can be set as a water storage tank (such as a raw water tank), or it can be set as a water storage tank or water storage bucket, etc. Such adjustments and changes to the specific setting type of the water storage device 2 do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0044] Preferably, such as Figures 4 to 11 As shown, water storage device 2 is the raw water tank.

[0045] It should be noted that, in practical applications, those skilled in the art do not impose any limitations on the specific shape of the filter component 11, as long as its filter surface can bulge out in the second direction. For example, the filter component 11 can be set as a spherical shape, or it can be set as an ellipsoidal shape, or it can be set as a conical shape, etc. Such adjustments and changes to the specific shape of the filter component 11 do not deviate from the principle and scope of this utility model, and should all be included within the protection scope of this utility model.

[0046] Preferably, such as Figures 1 to 3 , Figures 6 to 7 , Figures 10 to 11 As shown, the filter component 11 is spherical.

[0047] It should be noted that, in practical applications, those skilled in the art can configure the filter component 11 as a filter screen with multiple filter holes 111 for water filtration, or the filter component 11 as a filter cloth for water filtration through the pores in the filter cloth, etc. Such adjustments and changes to the specific configuration of the filter component 11 do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0048] Preferably, such as Figures 1 to 3 , Figure 7 and Figure 11 As shown, the filter element 11 is a filter screen with multiple filter holes 111, and the diameter of the filter holes 111 gradually increases along the water flow direction.

[0049] By setting the aperture of the filter hole 111 to gradually increase along the water flow direction, on the one hand, when the water in the water storage chamber 20 flows out through the water outlet pipe 21, the cross-section of the filter hole 111 near the water inlet is small and the water pressure is high, while the cross-section near the water outlet is large and the water pressure is low. This prevents impurities at the water inlet of the filter hole 111 from being sucked to the water outlet of the filter hole 111, further reducing dirt passing through the filter screen and improving the filtration effect of the filter element 1. On the other hand, during the processing of the filter component 11, when the filter hole 111 is formed, the mold needle can be made conical, thereby avoiding the mold needle from breaking, thus reducing the processing difficulty and improving the processing efficiency.

[0050] It should be noted that when processing the filter screen, a mold needle is required to form the filter holes 111. Since the aperture of the filter holes 111 is generally small, if the aperture of the filter holes 111 does not change along the water flow direction, a fine needle is required to pierce through them to form the filter holes 111. This poses a problem of the mold needle being prone to breakage, increasing the processing difficulty of the filter screen and affecting its processing efficiency. However, by setting the aperture of the filter holes 111 to gradually increase along the water flow direction, the mold needle used to process the filter component 11 can be a tapered needle, which greatly reduces the risk of mold needle breakage, thereby reducing the processing difficulty of the filter screen and improving its processing efficiency.

[0051] It should also be noted that, in practical applications, those skilled in the art do not impose any restrictions on the specific type of the installation component 12, as long as the filter component 11 can be installed on the water storage device 2. Such adjustments and changes to the specific type of the installation component 12 do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0052] In one embodiment, the mounting member 12 is configured to connect to the inner wall of the outlet pipe 21 to mount the filter member 11 on the inner side of the outlet pipe 21.

[0053] In another specific embodiment, the mounting member 12 is configured to connect to the outer wall of the outlet pipe 21 to mount the filter member 11 on the outside of the outlet pipe 21.

[0054] In another possible embodiment, such as Figure 7 and Figure 11 As shown, the mounting component 12 is configured to be able to connect to the inner wall of the water outlet pipe 21 to install the filter component 11 on the inner side of the water outlet pipe 21, and also to connect to the outer wall of the water outlet pipe 21 to install the filter component 11 on the outer side of the water outlet pipe 21.

[0055] Preferably, such as Figure 7 and Figure 11 As shown, the mounting component 12 can be connected to the inner wall of the water outlet pipe 21 to install the filter component 11 on the inner side of the water outlet pipe 21. The mounting component 12 can also be connected to the outer wall of the water outlet pipe 21 to install the filter component 11 on the outer side of the water outlet pipe 21.

[0056] With this configuration, when the mounting component 12 is compatible with the inner diameter of the water outlet pipe 21, the filter component 11 can be installed on the inner side of the water outlet pipe 21. When the mounting component 12 is compatible with the outer diameter of the water outlet pipe 21, the filter component 11 can be installed on the outer side of the water outlet pipe 21. This allows the mounting component 12 to be used with water outlet pipes 21 of different diameters, expanding the applicability of the filter element 1 and further enhancing the user experience.

[0057] Preferably, such as Figures 1 to 3 , Figure 7 and Figure 11 As shown, the mounting component 12 includes a mounting ring 121 and a mounting rib 122 disposed on the mounting ring 121. When the outer wall of the water outlet pipe 21 is adapted to the mounting ring 121, the mounting ring 121 is connected to the outer wall of the water outlet pipe 21 to install the filter component 11 on the outside of the water outlet pipe 21. When the inner wall of the water outlet pipe 21 is adapted to the mounting rib 122, the mounting rib 122 is connected to the inner wall of the water outlet pipe 21 to install the filter component 11 on the inner side of the water outlet pipe 21.

[0058] With this configuration, when the outer wall of the water outlet pipe 21 is adapted to the mounting ring 121, the mounting ring 121 can be connected to the outer wall of the water outlet pipe 21, thereby installing the filter element 11 on the outside of the water outlet pipe 21. When the inner wall of the water outlet pipe 21 is adapted to the mounting rib 122, the mounting rib 122 can be connected to the inner wall of the water outlet pipe 21, thereby installing the filter element 11 on the inside of the water outlet pipe 21. This allows the filter element 1 to be used with water outlet pipes 21 of different diameters. In addition, it simplifies the structure of the mounting element 12, makes installation more convenient, and further improves the user experience.

[0059] It should be noted that the installation component 12 is not limited to including a mounting ring 121 and a mounting rib 122 on the mounting ring 121. For example, the installation component 12 can also be configured to have an external thread that matches the internal thread of the water outlet pipe 21, and an internal thread that matches the external thread of the water outlet pipe 21. The filter component 11 is installed on the inside of the water outlet pipe 21 by making the external thread of the installation component 12 match the internal thread of the water outlet pipe 21, and the filter component 11 is installed on the outside of the water outlet pipe 21 by making the internal thread of the installation component 12 match the external thread of the water outlet pipe 21, etc. Such adjustments and changes to the specific structural form of the installation component 12 do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0060] Preferably, the mounting member 12 is configured to include a mounting ring 121 and a mounting rib 122 disposed on the mounting ring 121.

[0061] It should be noted that, in practical applications, those skilled in the art can place the water outlet pipe 21 inside the water storage chamber 20, or they can place the water outlet pipe 21 outside the water storage chamber 20, etc. Such adjustments and changes to the specific placement of the water outlet pipe 21 do not deviate from the principle and scope of this utility model, and should all be included within the protection scope of this utility model.

[0062] For example, such as Figure 6 and Figure 10 As shown, the water outlet pipe 21 is installed inside the water storage chamber 20 and located at the bottom of the water storage device 2.

[0063] It should also be noted that the outlet pipe 21 of the water storage device 2 is not limited to being located at the bottom of the water storage device 2. For example, the outlet pipe 21 can also be located at the top of the water storage device 2, or it can be located on the side wall of the water storage device 2, etc. Such adjustments and changes to the specific location of the outlet pipe 21 on the water storage device 2 do not deviate from the principle and scope of this utility model and should all be included within the protection scope of this utility model. Of course, preferably, the outlet pipe 21 of the water storage device 2 is located at the bottom of the water storage device 2.

[0064] The following two embodiments will be used to describe in detail the installation method of filter element 1 and water storage device 2.

[0065] Example 1:

[0066] like Figure 6 and Figure 7 As shown, the outer wall of the water outlet pipe 21 is adapted to the mounting ring 121. When installed, the mounting ring 121 is sleeved on the outside of the water outlet pipe 21 and the mounting ring 121 is sealed to the outer wall of the water outlet pipe 21.

[0067] Example 2:

[0068] like Figure 10 and Figure 11 As shown, the inner wall of the water outlet pipe 21 is adapted to the mounting rib 122. When installed, the water outlet pipe 21 is sleeved on the outside of the mounting rib 122 and the mounting rib 122 is sealed to the inner wall of the water outlet pipe 21.

[0069] It should be noted that, in practical applications, those skilled in the art can configure the mounting rib 122 to be fixedly connected to the mounting ring 121 or integrally formed, or the mounting rib 122 can be configured to be detachably connected to the mounting ring 121, etc. Such adjustments and changes to the specific connection method between the mounting rib 122 and the mounting ring 121 do not deviate from the principle and scope of this utility model, and should all be included within the protection scope of this utility model.

[0070] Preferably, the mounting rib 122 is fixedly connected to the mounting ring 121 or is integrally formed.

[0071] This design not only reduces the number of parts in filter element 1, but also facilitates the installation and removal of filter element 1.

[0072] More preferably, the mounting rib 122 and the mounting ring 121 are integrally formed.

[0073] By making the mounting rib 122 integrally formed with the mounting ring 121, the production efficiency of the mounting components can be improved and the production cost of the mounting components 12 can be reduced.

[0074] It should be noted that, in practical applications, those skilled in the art may set the number of mounting ribs 122 to only one, or the number of mounting ribs 122 may be set to at least two, etc. Such adjustments and changes to the specific number of mounting ribs 122 do not deviate from the principle and scope of this utility model, and should all be included within the protection scope of this utility model.

[0075] Preferably, such as Figures 1 to 3 , Figure 7 and Figure 11 As shown, the number of mounting ribs 122 is at least two.

[0076] It should be noted that, in practical applications, those skilled in the art can set the multiple mounting ribs 122 to have equal outer diameters, or they can set the multiple mounting ribs 122 to have unequal outer diameters, etc. Such flexible adjustments and changes do not deviate from the principles and scope of this utility model and should be included within the protection scope of this utility model.

[0077] In one specific embodiment, such as Figures 1 to 2, Figure 7 and Figure 11 As shown, the number of mounting ribs 122 is at least two and the mounting ribs 122 are distributed at intervals along the outer wall of the mounting ring 121, and the outer diameters of two adjacent mounting ribs 122 are equal.

[0078] This improves the installation stability and connection sealing of the filter element 1, thereby enhancing the filtration effect on the water flowing into the water storage device 2.

[0079] In another specific embodiment, such as Figure 3 As shown, the number of mounting ribs 122 is at least two and the mounting ribs 122 are distributed at intervals along the outer wall of the mounting ring 121, wherein the outer diameter of the mounting ribs 122 gradually decreases from the side closer to the filter member 11 to the side farther away from the filter member 11.

[0080] In another possible embodiment, the number of mounting ribs 122 is at least two and the mounting ribs 122 are distributed at intervals along the outer wall of the mounting ring 121, wherein the outer diameter of the mounting ribs 122 gradually increases from the side closer to the filter member 11 to the side farther away from the filter member 11 (not shown in the figure).

[0081] This configuration allows each mounting rib 122 to be adapted to water outlet pipes 21 with different inner diameters, thereby broadening the applicability of the filter element 1 and further enhancing the user experience.

[0082] Preferably, such as Figures 1 to 3 , Figure 7 and Figure 11 As shown, the filter element 1 also has a gripping part so that the user can use the gripping part to remove the filter element 11 from the water storage device 2.

[0083] By providing a grip, the filter element 1 can be easily removed from the water storage device 2, thereby reducing the difficulty of disassembling the installation structure and further improving the user experience.

[0084] It should be noted that, in practical applications, those skilled in the art can configure the filter component 11 and the mounting component 12 to be detachably connected, and configure the filter element 1 to be detached from the water storage device 2 by means of the gripping part. Alternatively, the filter component 11 and the mounting component 12 can be fixedly connected or integrally formed, and the filter element 1 can be detached from the water storage device 2 by means of the gripping part, etc. Such flexible adjustments and changes do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0085] Preferably, the filter component 11 and the mounting component 12 are fixedly connected or integrally formed.

[0086] By setting the filter element 11 and the mounting element 12 to be fixedly connected or integrally formed, the integrity of the filter element 1 can be improved, preventing the filter element 11 from falling off the mounting element 12. This improves the installation stability of the filter element 11 on the water storage device 2. When it is necessary to remove the filter element 1 from the water storage device 2, the filter element 11 and the mounting element 12 can be removed directly from the water storage device 2, improving the removal efficiency of the filter element 1.

[0087] It should be noted that, in practical applications, those skilled in the art can place the grip on the filter component 11, or the grip on the mounting component 12, or the grip on both the filter component 11 and the mounting component 12, etc. Such adjustments and changes to the specific placement of the grip on the filter element 1 do not deviate from the principle and scope of this utility model, and should all be included within the protection scope of this utility model.

[0088] Preferably, the grip portion is provided on the filter member 11.

[0089] It should be noted that, in practical applications, those skilled in the art can design the grip as a lifting rib 13, or as a lifting ring, or as a lifting handle, etc. Such adjustments and changes to the specific structural type of the grip do not deviate from the principle and scope of this utility model and should all be included within the protection scope of this utility model.

[0090] Preferably, such as Figures 1 to 3 , Figure 7 and Figure 11 As shown, the gripping part is a lifting rib 13 formed on the outer peripheral surface of the filter member 11.

[0091] It should be noted that, in practical applications, those skilled in the art can set the lifting rib 13 as a ring, or set the lifting rib 13 as a strip with multiple strip lifting ribs 13 distributed circumferentially at intervals on the filter component 11, or set the lifting rib 13 as any other possible structural form, etc. Such adjustments and changes to the specific setting type of the lifting rib 13 do not deviate from the principle and scope of this utility model, and should all be included within the protection scope of this utility model.

[0092] Preferably, such as Figures 1 to 3 , Figure 7 and Figure 11 As shown, the lifting rib 13 is a ring shape.

[0093] Preferably, such as Figures 1 to 3 , Figure 7 and Figure 11As shown, the lifting rod 13 has an inclined surface 131 on the side near the mounting member 12 so that a lifting force in the second direction can be applied to the inclined surface 131 to remove the filter member 11 from the water storage device 2.

[0094] By providing an inclined surface 131 on the lifting rib 13, when removing the filter component 11 from the water storage device 2, it is convenient for the user to apply a lifting force toward the second direction to the inclined surface 131, thereby making it easier to remove the filter component 11 from the water storage device 2 and further reducing the difficulty of disassembly.

[0095] In a second aspect, the present invention also provides a water storage device 2, which includes the filter element 1 described in any of the above claims.

[0096] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
