Description

Drive valve and filter element provided with drive valve Technical Field

[0001] The utility model relates to the field of water treatment, in particular to a component for a filtering kettle. Background Art

[0002] Typically, a filtered water pitcher consists of an upper basin for storing unfiltered water, a lower basin for storing filtered water, and a filter element connecting the upper and lower basins.

[0003] In order to avoid using the filter kettle without a filter cartridge or an incompatible filter cartridge, some filter kettles will have a shut-off valve on the lower basin and a drive valve on the filter cartridge. When there is no filter cartridge or the filter cartridge is incompatible, the shut-off valve closes the water flow channel. After the filter cartridge is inserted, the drive valve drives the shut-off valve to open the water flow channel.

[0004] Most existing drive valves are integrally formed with the filter element, which has problems such as high production difficulty and high production process requirements.

[0005] Utility Model Content

[0006] The purpose of the present utility model is to provide a drive valve to solve at least one of the above technical problems.

[0007] The utility model also aims to provide a filter element provided with a drive valve.

[0015] Preferably, the outer diameter of the lower port of the valve body gradually decreases from top to bottom.

[0016] Preferably, the outer side wall of the valve body is provided with spiral patterns.

[0017] A filter element provided with a drive valve comprises a water filtration filter element body, wherein the bottom of the filter element body is provided with a depression with an opening facing downward, and the filter element body is characterized in that the filter element further comprises a drive valve, wherein the drive valve comprises a disc-shaped valve cover, and a cylindrical valve body extending downward is provided on the lower end surface of the valve cover;

[0018] A first protrusion extending outward is provided at the outer edge of the valve cover, and a first gap is provided between two adjacent first protrusions;

[0025] Secondly, the utility model optimizes the structure of the driving valve and utilizes the first protrusion to make the driving valve applicable to more types of filter element bodies. The first gap provides space for the deformation of the first protrusion.

[0026] Then, the utility model optimizes the structure of the filter element body and can accommodate the driving valve by adding a recess, thereby eliminating the need to provide a separate package for the driving valve and effectively preventing the driving valve from being lost.

[0027] Finally, the driving valve of the present invention is interference-fitted in the groove of the filter element body, so that the driving valve can move with the movement of the filter element body.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0034] Specific embodiment 1, refer to Figures 1, 4 and 5

[0035] A filter element with an actuated valve comprises a water filtration element body 6 and an actuated valve 7. The actuated valve 7 comprises a disc-shaped valve cover 1, with a downwardly extending cylindrical valve body 2 disposed on its lower end surface. The outer edge of the valve cover 1 is provided with outwardly extending first protrusions 3, with a first gap defined between adjacent first protrusions 3. The bottom of the filter element body 6 is provided with a downwardly opening recess, into which the actuated valve 7 is inserted, with the outer edge of the first protrusion 3 forming an interference fit with the inner edge of the recess.

[0036] Instructions for use: Insert the drive valve 7 into the recess of the filter element body 6 to obtain the filter element body 6 with the drive valve 7 inserted. Insert the filter element body 6 with the drive valve 7 inserted into the filter kettle. The valve body 2 of the drive valve 7 will push open the stop valve, opening the water flow channel between the upper and lower basins of the filter kettle.

[0037] Specific embodiment 2, see Figures 2, 3, 4 and 5

[0038] A filter element with an actuated valve comprises a water filtration element body 6 and an actuated valve 7. The actuated valve 7 comprises a disc-shaped valve cover 1, with a downwardly extending cylindrical valve body 2 disposed on its lower end. A through hole 5 extends vertically through the valve cover 1, and upwardly extending second protrusions 4 are disposed on its upper end, with a second gap defined between adjacent second protrusions 4. A downwardly opening recess is disposed on the bottom of the filter element body 6, into which the actuated valve 7 is inserted. A water outlet is disposed at the bottom of the recess.

[0039] When in use, the stop valve is opened by driving the valve 7, and the filtered water then passes through the water outlet into the waterway surrounded by the second protrusion 4, the end cover, and the filter element body 6, and then along the waterway to the through hole 5, and finally passes through the valve body 2 and the stop valve into the lower plate.

[0040] Specific embodiment 3, refer to Figures 2, 3, 4 and 5

[0041] Based on Specific Example 2, the drive valve 7 is rotatable within the recess. A water outlet is defined at the bottom of the recess. The position of the water outlet corresponds exactly to the position of the second protrusion 4 on the drive valve 7, and the shape of the water outlet matches the shape of the drive valve 7. When the drive valve 7 rotates so that the second protrusion 4 is directly below the water outlet, the second protrusion 4 closes the water outlet. When the drive valve 7 rotates so that the second protrusion 4 is no longer below the water outlet, the water outlet is fully open. This allows for regulation of the filtration speed of the filter element.

[0042] The above three specific embodiments can be combined with each other.

[0043] The end cover of the specific embodiment 1 may also be provided with a second protrusion 4 and a through hole 5. In the specific embodiment 1, the second protrusion 4 and the through hole 5 serve to release the airflow when the stop valve is opened.

[0044] In the above three embodiments, it is preferred that the through hole 5 is opened in the center of the valve cover 1, and the second protrusion 4 is a protrusion extending along the radial direction of the valve cover 1. This facilitates production and processing while guiding the flow direction of air or water.

[0045] In the above three embodiments, it is preferred that the first protrusions 3 are arranged at equal intervals and are preferably fan-shaped.

[0046] In the three aforementioned embodiments, through-hole 5 communicates with the inner cavity of valve body 2. Valve body 2 is thus utilized to drive the rotation of the filter element limit valve, guide the insertion of an external component, or direct the flow of filtered water. The outer wall of valve body 2 is preferably provided with a spiral pattern, which may be a spiral protrusion or a spiral depression, thereby facilitating smoother rotation of the driven valve 7.

[0047] In the above three embodiments, preferably, the through hole 5 is opened in the center of the valve cover 1, and the second protrusion 4 is a protrusion extending radially along the valve cover 1. This facilitates production and processing while allowing the filtered water to flow toward the middle. Further preferably, the width of the second protrusion 4 gradually decreases from bottom to top. For example: one side of the cross-section of the second protrusion 4 is in the shape of a line segment extending in the vertical direction, and the other side is in the shape of a circular arc or a line segment extending obliquely. This makes it easy to insert or slide out of the water outlet. There are preferably four second protrusions 4. The four second protrusions 4 are arranged at equal intervals to form a ring.

[0048] In the three aforementioned embodiments, the height of the upper end surface of the end cap preferably decreases gradually from the outer edge toward the center, thereby allowing water filtered by the filter element body 6 to flow toward the central through-hole 5 under the action of gravity, while reducing water flowing toward the edges. The top of the second protrusion 4 is preferably at a consistent height throughout. This allows the depth of the channel formed by the second protrusion 4, the end cap, and the recessed bottom to gradually increase from the edge toward the center.

[0049] In the above three embodiments, the outer diameter of the lower port of the valve body 2 gradually decreases from top to bottom, so that the bottom of the valve body 2 is inclined. This inclined surface can be used to easily pierce the flow-limiting component on the docking part of the filter kettle docked with the drive valve 7, such as an aluminum foil or elastic baffle used to block the water flow channel.

[0050] In the three embodiments described above, the depth of the recess is preferably greater than the height of the drive valve 7, so that the drive valve 7 is completely accommodated within the recess. The outer edge of the first protrusion 3 forms an interference fit with the inner edge of the recess, so that the drive valve 7 does not fall off the water filter element body 6 and can move with the water filter element body 6, thus eliminating the cumbersome installation of two separate components.

[0051] The above shows and describes the basic principles and main features of the present invention, as well as the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
