Description

Technical Field

[0001] The present invention relates to the technical field of water purification, and particularly provides a filter element for a water storage device and a water storage device. Background Art

[0002] With the improvement of people's living standards, the demand for drinking water is also increasing. Water purification equipment such as water purifiers and integrated water dispensers has gradually become an essential drinking water facility in people's daily lives.

[0003] Existing water purification equipment usually comes with a raw water tank for water storage. When the raw water tank supplies water, a filter screen is usually set at the water outlet to filter and intercept larger particles of impurities, preventing large particle impurities from entering the filter element of the water purification equipment.

[0004] Existing filter screens generally adopt the form of inserting a stainless steel wire mesh into injection molding, or the form of elastic snap connection between a stainless steel mesh sheet and a silicone sleeve. However, both forms of filter screens have the problem that the filter screen is easily blocked by impurities, resulting in poor user experience. Summary of the Invention

[0005] The present invention aims to solve at least to some extent the above technical problems, that is, at least to some extent solve the problem that the existing filter screen is easily blocked by impurities, resulting in poor user experience.

[0006] In a first aspect, the present invention provides a filter element for a water storage device. The water storage device has a water storage cavity and a water outlet pipe, and the water outlet pipe is communicated with the water storage cavity so that the water in the water storage cavity flows out along a first direction through the water outlet pipe. The filter element includes a connected filter member and an installation member. The installation member is used to install the filter member on the water outlet pipe, and the filter member can filter the water flowing out of the water storage cavity. Among them, the filtering surface of the filter member protrudes towards a second direction, and the second direction is opposite to the first direction.

[0007] In the preferred technical solution of the above filter element for a water storage device, the filter member is spherical, ellipsoidal or conical; and / or, the filter member is a filter screen, and the filter screen has a plurality of filter holes, and the aperture of the filter holes gradually increases along the water flow direction.

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

[0009] In the above preferred technical solution of the filter element for the water storage device, the mounting member includes a mounting ring and mounting ribs provided 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 mount the filter member outside the water outlet pipe; when the inner wall of the water outlet pipe is adapted to the mounting ribs, the mounting ribs are connected to the inner wall of the water outlet pipe to mount the filter member inside the water outlet pipe.

[0010] In the above preferred technical solution of the filter element for the water storage device, the number of the mounting ribs is at least two and they are spaced apart along the outer wall of the mounting ring. Among them, the outer diameters of two adjacent mounting ribs are equal.

[0011] In the above preferred technical solution of the filter element for the water storage device, the number of the mounting ribs is at least two and they are spaced apart along the outer wall of the mounting ring. Among them: the outer diameter of the mounting rib gradually increases from the side close to the filter member to the side far from the filter member; or, the outer diameter of the mounting rib gradually decreases from the side close to the filter member to the side far from the filter member.

[0012] In the above preferred technical solution of the filter element for the water storage device, the filter element further has a holding portion for the user to detach the filter member from the water storage device by means of the holding portion; and / or, the filter member and the mounting member are fixedly connected or integrally formed.

[0013] In the above preferred technical solution of the filter element for the water storage device, the holding portion is a lifting rib formed on the outer peripheral surface of the filter member.

[0014] In the above preferred technical solution of the filter element for the water storage device, the lifting rib is annular; and / or, an inclined surface is provided on the side of the lifting rib close to the mounting member, so that the user applies a pulling force in the second direction to the inclined surface to detach the filter member from the water storage device.

[0015] In a second aspect, the present invention further provides a water storage device, and the water storage device includes the filter element for the water storage device according to any one of the above.

[0016] When the above-mentioned preferred technical solution is adopted, by configuring the filter element to be a filter component and a mounting component, the filter component can be installed on the water outlet pipe through the mounting component. When the water in the water storage device flows out through the water outlet pipe, the water flowing out of the water storage chamber can be filtered by the filter component. By configuring the filter surface of the filter component to protrude toward the second direction, pollutants in the water can be prevented from accumulating on the surface of the filter component, thereby preventing 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 hole to gradually increase along the direction of water flow, on the one hand, when the water in the water storage chamber flows out through the water outlet pipe, the cross-section of the filter hole close to the water inlet end can be made small and the water pressure can be high, while the cross-section of the side close to the water outlet end can be made large and the water pressure can be low, thereby preventing impurities at the water inlet end of the filter hole from being sucked to the water outlet end of the filter hole, further reducing dirt from passing through the filter net, and improving the filtering effect of the filter element. On the other hand, during the processing of the filter component, when the filter hole is formed, the mold needle can be made conical, thereby avoiding the mold needle from breaking, thereby reducing the processing difficulty and improving the processing efficiency.

[0018] Furthermore, when the mounting component is matched with the inner diameter of the water outlet pipe, the filter component can be installed on the inner side of the water outlet pipe, and when the mounting component is matched with the outer diameter of the water outlet pipe, the filter component can be installed on the outer side of the water outlet pipe. This makes the mounting component suitable for the installation of water outlet pipes of different diameters, thereby expanding the application range of the filter element and further improving the user experience.

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

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

[0021] Furthermore, by providing a gripping portion, 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] In addition, the water storage device further provided by the present invention on the basis of the above-mentioned filter element for the water storage device includes the above-mentioned filter element for the water storage device, and thus has the beneficial effects possessed by the above-mentioned filter element for the water storage device. Compared with the water storage device before improvement, the water storage device of the present invention has a better filtering effect when discharging water, is less likely to be blocked, and provides a better user experience.

[0037] The preferred implementation manners of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0038] It should be noted that in the description of the present invention, the terms "upper", "lower", "inner", "outer", etc. indicating directions or position relationships are based on the directions or position relationships shown in the drawings. This is only for convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0039] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "mount", "set", "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Based on the problem that the existing filter screen for the original water tank mentioned in the background technology is prone to accumulate impurities, resulting in a poor user experience, the present invention provides a filter element for a water storage device.

[0041] Specifically, please refer to Figures 1 to 11 , the water storage device 2 of the present invention has a water storage cavity 20 and a water outlet pipe 21. The water outlet pipe 21 is communicated with the water storage cavity 20 so that the water in the water storage cavity 20 flows out along the first direction through the water outlet pipe 21. The filter element 1 includes a connected filter member 11 and a mounting member 12. The mounting member 12 is used to mount the filter member 11 on the water outlet pipe 21. The filter member 11 can filter the water flowing out from the water storage cavity 20. Among them, the filtering surface of the filter member 11 protrudes towards the second direction, and the second direction is opposite to the first direction.

[0042] With such a setting, when the water in the water storage device 2 flows out through the water outlet pipe 21, the water flowing out from the water storage cavity 20 can be filtered by the filtering member 11. By setting the filtering surface of the filtering member 11 to be convex towards the second direction, it is possible to prevent pollutants in the water from accumulating on the surface of the filtering member 11, thereby avoiding clogging of the filtering member 11 by pollutants, prolonging the service life of the filtering member 11, and greatly improving the user experience.

[0043] It should be noted that the present invention does not make any limitation on the specific type of the water storage device 2 applicable to the filtering element 1. For example, the water storage device 2 can be set as a water storage tank (such as an original water tank), or the water storage device 2 can also be set as a water storage tank or a water 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 the present invention and should be included in the protection scope of the present invention.

[0044] Preferably, as Figures 4 to 11 shown, the water storage device 2 is an original water tank.

[0045] It should be noted that in practical applications, those skilled in the art do not make any limitation on the specific shape of the filtering member 11, as long as its filtering surface can be convex towards the second direction. For example, the filtering member 11 can be set as a spherical shape, or the filtering member 11 can also be set as an ellipsoidal shape, or the filtering member 11 can also be set as a conical shape, etc. Such adjustments and changes to the specific setting shape of the filtering member 11 do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0046] Preferably, as Figures 1 to 3 、 Figures 6 to 7 、 Figures 10 to 11 shown, the filtering member 11 is spherical.

[0047] It should be noted that in practical applications, those skilled in the art can set the filtering member 11 as a filter screen with a plurality of filter holes 111 for filtering water through the filter holes 111, or the filtering member 11 can also be set as a filter cloth for filtering water through the pores on the filter cloth, etc. Such adjustments and changes to the specific setting form of the filtering member 11 do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0048] Preferably, as Figures 1 to 3 、 Figure 7 and Figure 11 shown, the filtering member 11 is a filter screen with a plurality of filter holes 111, and the aperture of the filter holes 111 gradually increases along the water flow direction.

[0049] By such a setting, that is, by setting the aperture diameter of the filtering holes 111 to gradually increase along the water flow direction. On the one hand, when the water in the water storage cavity 20 flows out through the water outlet pipe 21, it can be ensured that the cross-section of the filtering holes 111 near the water inlet end is small and the water pressure is large, while the cross-section on the side near the water outlet end is large and the water pressure is small. Thus, it can prevent impurities at the water inlet end of the filtering holes 111 from being sucked to the water outlet end of the filtering holes 111, further reducing the dirt passing through the filter net and improving the filtering effect of the filtering element 1. On the other hand, during the processing of the filtering member 11, when forming the filtering holes 111, the die needle can be made conical, thereby avoiding the fracture of the die needle, further reducing the processing difficulty and improving the processing efficiency.

[0050] It should be noted that when processing the filter net, a die needle is required to form the filtering holes 111. Since the aperture diameter of the filtering holes 111 is generally relatively small, if the aperture diameter of the filtering holes 111 does not change along the water flow direction, a thinner needle needs to be used for piercing to form the filtering holes 111, which has the problem that the die needle is prone to fracture, increasing the processing difficulty of the filter net and affecting the processing efficiency of the filter net. However, setting the aperture diameter of the filtering holes 111 to gradually increase along the water flow direction can make the die needle for processing the filtering member 11 a conical needle, greatly reducing the fracture risk of the die needle, thereby reducing the processing difficulty of the filter net and improving the processing efficiency of the filter net.

[0051] It also should be noted that in practical applications, those skilled in the art do not make any limitations on the specific setting type of the installation member 12, as long as the filtering member 11 can be installed on the water storage device 2. Such adjustments and changes to the specific setting type of the installation member 12 do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0052] In a specific embodiment, the installation member 12 is set to be able to connect with the inner wall of the water outlet pipe 21 to install the filtering member 11 inside the water outlet pipe 21.

[0053] In another specific embodiment, the installation member 12 is set to be able to connect with the outer wall of the water outlet pipe 21 to install the filtering member 11 outside the water outlet pipe 21.

[0054] In another possible embodiment, as Figure 7 and Figure 11 shown, the installation member 12 is set to be able to connect with the inner wall of the water outlet pipe 21 to install the filtering member 11 inside the water outlet pipe 21, and also be able to connect the installation member 12 with the outer wall of the water outlet pipe 21 to install the filtering member 11 outside the water outlet pipe 21.

[0055] Preferably, as Figure 7 and Figure 11As shown, the mounting member 12 can be connected to the inner wall of the outlet pipe 21 to install the filtering member 11 inside the outlet pipe 21, and the mounting member 12 can also be connected to the outer wall of the outlet pipe 21 to install the filtering member 11 outside the outlet pipe 21.

[0056] With such a setting, when the mounting member 12 is adapted to the inner diameter of the outlet pipe 21, the filtering member 11 can be installed inside the outlet pipe 21, and when the mounting member 12 is adapted to the outer diameter of the outlet pipe 21, the filtering member 11 can be installed outside the outlet pipe 21. Thus, the mounting member 12 can be applied to the installation of outlet pipes 21 with different diameters, expanding the applicable range of the filtering element 1 and further enhancing the user experience.

[0057] Preferably, as Figures 1 to 3 、 Figure 7 and Figure 11 shown, the mounting member 12 includes a mounting ring 121 and mounting ribs 122 provided on the mounting ring 121. When the outer wall of the outlet pipe 21 is adapted to the mounting ring 121, the mounting ring 121 is connected to the outer wall of the outlet pipe 21 to install the filtering member 11 outside the outlet pipe 21. When the inner wall of the outlet pipe 21 is adapted to the mounting ribs 122, the mounting ribs 122 are connected to the inner wall of the outlet pipe 21 to install the filtering member 11 inside the outlet pipe 21.

[0058] With such a setting, when the outer wall of the outlet pipe 21 is adapted to the mounting ring 121, the mounting ring 121 can be connected to the outer wall of the outlet pipe 21, thereby installing the filtering member 11 outside the outlet pipe 21. When the inner wall of the outlet pipe 21 is adapted to the mounting ribs 122, the mounting ribs 122 can be connected to the inner wall of the outlet pipe 21, thereby installing the filtering member 11 inside the outlet pipe 21. This enables the filtering element 1 to be applicable to outlet pipes 21 with different diameters. In addition, the structure of the mounting member 12 can be made simpler and the installation more convenient, further enhancing the user experience.

[0059] It should be noted that the installation member 12 is not limited to including the installation ring 121 and the installation ribs 122 provided on the installation ring 121. For example, the installation member 12 can also be provided with an external thread adapted to the internal thread of the inner wall of the water outlet pipe 21, and the installation member 12 has an internal thread adapted to the external thread of the outer wall of the water outlet pipe 21. By mating the external thread of the installation member 12 with the internal thread of the inner wall of the water outlet pipe 21, the filtering member 11 is installed inside the water outlet pipe 21. By mating the internal thread of the installation member 12 with the external thread of the outer wall of the water outlet pipe 21, the filtering member 11 is installed outside the water outlet pipe 21, and so on. Such adjustments and changes to the specific structural form of the installation member 12 do not deviate from the principles and scope of the present invention and should all be included in the protection scope of the present invention.

[0060] Of course, preferably, the installation member 12 is provided to include the installation ring 121 and the installation ribs 122 provided on the installation ring 121.

[0061] It should be noted that in practical applications, those skilled in the art can set the water outlet pipe 21 inside the water storage cavity 20, or the water outlet pipe 21 can also be set outside the water storage cavity 20, and so on. Such adjustments and changes to the specific installation position of the water outlet pipe 21 do not deviate from the principles and scope of the present invention and should all be included in the protection scope of the present invention.

[0062] Exemplarily, as Figure 6 and Figure 10 shown, the water outlet pipe 21 is provided inside the water storage cavity 20 and at the bottom of the water storage device 2.

[0063] It should also be noted that the water outlet pipe 21 of the water storage device 2 is not limited to being provided at the bottom of the water storage device 2. For example, the water outlet pipe 21 can also be provided at the top of the water storage device 2, or the water outlet pipe 21 can also be provided on the side wall of the water storage device 2, and so on. Such adjustments and changes to the specific installation position of the water outlet pipe 21 on the water storage device 2 do not deviate from the principles and scope of the present invention and should all be included in the protection scope of the present invention. Of course, preferably, the water outlet pipe 21 of the water storage device 2 is provided at the bottom of the water storage device 2.

[0064] The following will introduce in detail the installation method of the filtering element 1 and the water storage device 2 in combination with the following two embodiments.

[0065] Embodiment 1:

[0066] As Figure 6 and Figure 7 shown, the outer wall of the water outlet pipe 21 is adapted to the installation ring 121. In the installed state, the installation ring 121 is sleeved outside the water outlet pipe 21 and the installation ring 121 is sealingly connected to the outer wall of the water outlet pipe 21.

[0067] Example 2:

[0068] As Figure 10 and Figure 11 shown, the inner wall of the water outlet pipe 21 is adapted to the installation rib 122. In the installed situation, the water outlet pipe 21 is sleeved outside the installation rib 122 and the installation rib 122 is sealingly connected 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 set the installation rib 122 to be fixedly connected or integrally formed with the installation ring 121. Or, the installation rib 122 can also be set to be detachably connected to the installation ring 121, etc. Such adjustments and changes to the specific connection method between the installation rib 122 and the installation ring 121 do not deviate from the principle and scope of the present invention and should all be included in the protection scope of the present invention.

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

[0071] Through such a setting, not only can the number of components of the filter element 1 be reduced, but also the installation and disassembly of the filter element 1 can be facilitated.

[0072] Further preferably, the installation rib 122 is integrally formed with the installation ring 121.

[0073] By setting the installation rib 122 to be integrally formed with the installation ring 121, the production efficiency of the installation component can be improved and the production cost of the installation component 12 can be reduced.

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

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

[0076] It should be noted that in practical applications, those skilled in the art can set the outer diameters of the multiple installation ribs 122 to be all equal, or the outer diameters of the multiple installation ribs 122 can also be set to be all unequal, etc. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention and should all be included in the protection scope of the present invention.

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

[0078] In this way, the installation stability and connection sealing performance of the filter element 1 can be improved, so that the filtering effect on the water flowing into the water storage device 2 can be improved.

[0079] In another specific embodiment, as Figure 3 shown, the number of the mounting ribs 122 is at least two, and the mounting ribs 122 are spaced apart along the outer wall of the mounting ring 121, wherein the outer diameter of the mounting rib 122 gradually decreases from the side close to the filtering member 11 to the side far from the filtering member 11.

[0080] In another possible specific embodiment, the number of the mounting ribs 122 is at least two, and the mounting ribs 122 are spaced apart along the outer wall of the mounting ring 121, wherein the outer diameter of the mounting rib 122 gradually increases from the side close to the filtering member 11 to the side far from the filtering member 11 (not shown in the figure).

[0081] With such a setting, each mounting rib 122 can be applicable to the water outlet pipes 21 with different inner diameters, so that the applicable range of the filter element 1 is wider, and the user experience is further improved.

[0082] Preferably, as Figures 1 to 3 , Figure 7 and Figure 11 shown, the filter element 1 further has a holding portion, so that the user can remove the filtering member 11 from the water storage device 2 by means of the holding portion.

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

[0084] It should be noted that in practical applications, those skilled in the art can set the filtering member 11 and the mounting member 12 to be detachably connected, and the filter element 1 is set to only remove the filtering member 11 from the water storage device 2 through the holding portion. Or, the filtering member 11 and the mounting member 12 can also be set to be fixedly connected or integrally formed, and the filter element 1 is set to remove the filtering member 11 and the mounting member 12 from the water storage device 2 through the holding portion, etc. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

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

[0086] By such a setting, that is, by setting the filtering member 11 and the mounting member 12 to be fixedly connected or integrally formed, the integrity of the filter element 1 can be improved, preventing the filtering member 11 from falling off the mounting member 12, thereby improving the mounting stability of the filtering member 11 on the water storage device 2. When it is necessary to disassemble the filter element 1 from the water storage device 2, the filtering member 11 and the mounting member 12 can be directly disassembled from the water storage device 2 together, improving the disassembly efficiency of the filter element 1.

[0087] It should be noted that in practical applications, those skilled in the art can set the holding part on the filtering member 11, or, alternatively, can set the holding part on the mounting member 12, or, further, can also set the holding part on both the filtering member 11 and the mounting member 12, etc. Such adjustments and changes to the specific setting position of the holding part on the filter element 1 do not deviate from the principle and scope of the present invention and should all be included in the protection scope of the present invention.

[0088] Preferably, the holding part is set on the filtering member 11.

[0089] It should be noted that in practical applications, those skilled in the art can set the holding part as the lifting rib 13, or, alternatively, can set the holding part as a lifting ring, or, further, can also set the holding part as a lifting handle, etc. Such adjustments and changes to the specific structural type of the holding part do not deviate from the principle and scope of the present invention and should all be included in the protection scope of the present invention.

[0090] Preferably, as Figures 1 to 3 、 Figure 7 and Figure 11 shown, the holding part is the lifting rib 13 formed on the outer peripheral surface of the filtering member 11.

[0091] It should be noted that in practical applications, those skilled in the art can set the lifting rib 13 to be annular, or, alternatively, can set the lifting rib 13 to be strip-shaped and a plurality of strip-shaped lifting ribs 13 are circumferentially spaced on the filtering member 11, or, further, can also set the lifting rib 13 to 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 the present invention and should all be included in the protection scope of the present invention.

[0092] Preferably, as Figures 1 to 3 、 Figure 7 and Figure 11 shown, the lifting rib 13 is annular.

[0093] Preferably, as Figures 1 to 3 、 Figure 7 and Figure 11As shown, an inclined surface 131 is provided on one side of the lifting rib 13 close to the mounting member 12, so as to apply a lifting force in the second direction to the inclined surface 131 to detach the filtering member 11 from the water storage device 2.

[0094] By providing the inclined surface 131 on the lifting rib 13, when the filtering member 11 is detached from the water storage device 2, it is convenient for the user to apply a lifting force in the second direction to the inclined surface 131, so as to facilitate the detachment of the filtering member 11 from the water storage device 2 and further reduce the difficulty of detachment.
