Description

TECHNICAL AREA The present disclosure relates to the field of valves, in particular a valve actuating device, an arrangement comprising a valve and a valve actuating device, and a liquid container. STATE OF THE ART Currently, water treated during water filtration does not meet drinking water standards and must still be filtered. Water filtration is a process for treating water in which suspended solids are removed from the water using a filter medium to obtain fresh water. Water filtration requires a water filtration system that includes a reservoir for collecting unfiltered liquid and has an outlet at its bottom. A cartridge is located near the outlet, through which the liquid must flow before exiting the reservoir. A distinction is made between gravity-driven and pressure-driven systems. Both gravity-driven and pressure-driven systems have a corresponding cartridge and a reservoir with a suitable connection. In a gravity-fed filtration system, the liquid reservoir serves to collect unfiltered water, which is typically located at the bottom of the reservoir. A filter element is provided within the reservoir, and the bottom of the reservoir has an outlet so that the filtered water flowing out from below the filter element can flow into a collection container located below the reservoir. The outlet is generally equipped with a valve to prevent unfiltered water from flowing directly into the collection container and contaminating the filtered purified water when the filter element is not installed. In the prior art, the valve is actuated by a spiral axial movement. The structure is complex, and opening the valve requires working from inside the liquid container. Operation is cumbersome and can easily lead to secondary contamination of the liquid container. SUMMARY A main objective of the present disclosure is to overcome at least one of the aforementioned disadvantages of the prior art and to provide a valve actuation device that has a simple structure, is easy to operate, allows for quick separation of the valve seat and valve body, and promotes the unimpeded flow of liquid in the liquid container.

The following describes various exemplary embodiments of the present disclosure with reference to the drawings that form part of the present disclosure, whereby different exemplary structures, systems, and steps of various aspects of the present disclosure can be implemented in an exemplary manner. It is understood that other specific technical solutions of the components, structures, exemplary devices, systems, and steps may be used and may be structurally and functionally modified without departing from the scope of the present disclosure. Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings in order to make the aforementioned objectives, features and advantages of the present disclosure clearly understandable. As shown in Figures 1, 2, 3, 4, 5 to 6, and 9, 10 to 11, a valve actuating device 100 of the present disclosure is mounted on a valve 900. The valve 900 comprises a valve body 901, in which a through-opening 1101 is provided, and a valve seat 902 on which the valve body 901 is arranged. The valve actuating device 100 comprises a body 101 and at least one claw 103. The body 101 has an upper end 102 for carrying the claw 103. The claw 103 is arranged at the upper end 102 and is engaged with the valve seat 902 via the through-opening 1101, the claw 103 separating the valve body 901 from the valve seat 902. When using the valve actuation device, a user's hand holds the body 101 for actuation. The claw 103 is connected to the body 101 via its upper end 102, so that when the user's hand actuates the body 101, it also moves the claw 103.The body 101 is driven by the user's hand, which drives the claw 103 to pass through the through-hole 1101 in the valve seat 902, so that the claw 103 lifts the valve body 901 arranged on the valve seat 902 upwards, so that the valve body 901 is separated from the valve seat 902 and the fluid can flow out through a gap formed after separation between the valve seat 902 and the valve body 901. The valve actuating device 100, the claw 103, and / or the body 101 can be made of a material with a specific elasticity, for example, PP, PE, ABS, nylon, or the like. The claw and the body can be formed in one piece. The number of claws can be more than one, for example, two, three, five, or the like. In this embodiment, the number of claws 103 is three, arranged at an angular interval of 120°. The claws 103 are distributed such that they form a virtual cylinder with the centerline of the body 101 as its axis. Alternatively, one or two of the claws 103 can be replaced by support columns without a suspension function in order to completely or partially separate the valve seat 902 from the valve body 901. In this embodiment, the number of through-openings 1101 in the valve seat 902 is also three and corresponds to the number of claws 103; the three through-openings 1101 are fan-shaped and arranged at intervals of 120°; and the arcuate inner walls of the through-openings 1101 lie on the same circumference and correspond to the positions of the claws 103. Since the valve is generally a rotating body, three through-openings 1101 are provided in a fan-shaped arrangement, which are arranged at the upper edge of the fluid channel 201 and extend along the circumferential direction of the fluid channel 201 to allow more convenient engagement with the claw 103 of the valve actuating device 100 of the present disclosure. That is to say, the arrangement position of the through-opening 1101 and the arrangement position of the claw 103 are related to each other, correspond to each other, and influence each other. The upper end 102 comprises a flow-guiding surface inclined towards the liquid channel 201, the flow-guiding surface being arranged between several claws 103. In this embodiment, as shown in Fig. 2, the liquid channel 201, through which the liquid flows, is arranged in the center of the body 101. In some other embodiments, the liquid channel 201 can be omitted as long as the liquid can flow out. In this embodiment, the claw 103, as shown in Fig. 3, comprises a projection and a connecting arm 302. The projection includes a hook 301 and, in some other embodiments, additionally a tab 601 (as shown in Fig. 6). The tab may comprise an arcuate surface projecting horizontally away from the body 101 from an outer wall, in particular a semicircular or hemispherical convex surface. The connecting arm 302 has one end connected to the upper end 102 of the body 101 and another end on which the hook 301 is arranged. The hook 301 is engaged with the valve seat 902. The hook 301 is primarily designed to allow the claw 103 to engage with the valve seat surface of the valve seat 902 around the through-hole 1101 and against the valve body 901 via the through-hole 1101 in the valve seat 902.Since the hook has a certain height to lift the valve body 901, preventing the valve body 901 from contacting the valve seat 902, a gap is formed. The connecting arm 302 primarily serves to connect the hook 301 to the body 101. Identical areas of several claws 103 are distributed across a virtual cross-section of a virtual cylinder to form multiple circles with different diameters. In this embodiment, the hook 301, as shown in Fig. 4, comprises a first plane 401, which is perpendicular to the connecting arm 302, and a second inclined plane 402, which extends from the first plane 401 in a direction away from the connecting arm 302. Since an inner wall surface of the through-opening 1101 in the valve seat 902 is perpendicular to the valve seat surface of the valve seat 902 opposite the valve body 901, the hook 301 is provided with the first plane 401 perpendicular to the connecting arm 302, so that the claw 103 engages with the valve seat surface of the valve seat 902 around the through-opening 1101 and opposite the valve body 901 via the through-opening 1101 in the valve seat 902 in order to lift the valve body 901, so that the fluid flows out of the gap formed after the separation between the valve seat 902 and the valve body 901.The hook 301 is provided with the second inclined plane 402, which extends from the first plane 401 in a direction away from the connecting arm 302 and can perform a guiding function when the claw 103 passes through the through-opening 1101 in the valve seat 902. Since the first plane 401 of the hook 301 is required for the claw 103 to engage with the valve seat surface of the valve seat 902 around the through-opening 1101 and against the valve body 901, the diameter of a circle formed by a region connecting the second inclined plane 402 and the first plane 401 is slightly larger than the diameter of a circle formed by the arcuate inner wall of the through-opening 1101 in the valve seat 902.The second inclined plane 402 extends away from the connecting arm 302, so that the diameter of a circle formed by an upper end position of the hook 301 is smaller than the diameter of a circle formed by the arcuate inner wall of the through-hole 1101 in the valve seat 902, allowing the claw 103 to pass smoothly through the through-hole 1101 in the valve seat 902. In this embodiment, the distance between the first plane 401 of the hook 301 and the upper end 102 of the body 101 is greater than the length of the through-opening 1101. This ensures that there is a certain distance between the upper end 102 of the body 101 and the underside of the valve seat 902, allowing the liquid to flow out of the gap formed between the upper end 102 of the body 101 and the underside of the valve seat 902. In this embodiment, the body 101 is cylindrical, and the claws 103 are evenly distributed at the upper end 102 of the body 101, which is advantageous for manual operation and a simple manufacturing process. The body 101 can also be triangular, square, hexagonal, or the like. The upper end 102 formed on the body 101 serves to limit the travel of the claw 103 when the claw 103 passes through the through-hole 1101 in the valve seat 902. When the upper end 102 touches the underside of the valve seat 902, this means that the hook 301 of the claw 103 has completely penetrated the through-hole 1101 in the valve seat 902, so that the first level 401 of the hook 301 of the claw 103 has engaged on the valve seat 902, thereby separating the valve body 901 from the valve seat 902 and allowing the fluid to flow out of the gap formed after separation between the valve seat 902 and the valve body 901. In this embodiment, the connecting arm 302 of the claw 103 has an outer wall 403. When the claw 103 penetrates the through-opening 1101 in the valve seat 902, a gap exists between the outer wall 403 of the connecting arm 302 and the arcuate inner wall of the through-opening 1101. This allows the liquid to flow out of the gap formed as described above. As shown in Fig. 7, in a second embodiment of the valve actuating device 100 of the present disclosure, the valve actuating device 100 comprises a body 101 and at least one claw 103. The claw 103 comprises a hook 301 and a connecting arm 302. The connecting arm 302 is arranged at an upper end 102, and the hook 301 is arranged on the connecting arm 302. The connecting arm 302 has an outer wall 403. The hook 301 comprises a first slope 701, which forms an obtuse angle α with the outer wall 403 of the connecting arm 302, and a second slope 402, which extends from the first slope 701 in a direction away from the connecting arm 302. The first inclined surface 701 is primarily designed to allow a hand to grasp the body 101 in order to pull the valve actuating device 100 downwards during disassembly.Under the guidance of the first inclined plane 701, the elasticity of the claw causes the connecting arm 302 to pull the hook 301 towards the center of the valve actuating device, so that the hook 301 can be moved downwards out of the through-hole 1101 in the valve seat 902 in order to disassemble the valve actuating device 100 from the valve 900. As shown in Fig. 8, in a third embodiment of the valve actuating device 100 of the present disclosure, the valve actuating device 100 comprises a body 101 and at least one claw 103. The claw 103 comprises a hook 301 and a connecting arm 302. The connecting arm 302 is arranged at an upper end 102. The hook 301 is arranged on the connecting arm 302. The hook 301 comprises a first plane 401, which is perpendicular to the connecting arm 302, and a second inclined plane 402, which extends from the first plane 401 in a direction away from the connecting arm 302. A chamfer 801 is provided at a connection point between the first plane 401 and the connecting arm 302. The chamfer 801 is primarily designed to allow a hand to grasp the body 101 in order to pull the valve actuating device 100 downwards during disassembly.Under the guidance of the chamfer 801, the elasticity of the claw causes the connecting arm 302 to pull the hook 301 towards the center of the valve actuating device, so that the hook 301 can be moved downwards out of the through-hole 1101 in the valve seat 902 in order to disassemble the valve actuating device 100 from the valve 900. In some other embodiments, the number of through-holes 1101 in the valve seat 902 is greater than the number of claws 103. In this way, when the claw 103 passes through the through-hole 1101 in the valve seat 902 to lift the valve body 901, the fluid can flow out of other through-holes 1101 without claws. As shown in Figures 12, 13, 14, 15, 16 to 17, specific structures of the valve body 901 and the valve seat 902 of the valve 900, which is actuated by the valve actuating device 100 of the present disclosure, are shown. The valve seat 902 has a substantially cylindrical shape, and the valve body 901 has a surface matching the valve seat 902, the shape of which corresponds to at least one section of a conical side surface.The valve body 901 has an axial end that forms an adjustment of the valve body 901 which can selectively impede the flow of fluid through the through-hole 1101 in the valve seat 902; that is, when the valve actuating device 100 is not mounted, the surface of the valve body 901 rests against the valve seat 902 to prevent the fluid from flowing through the through-hole 1101 in the valve seat 902; and when the valve actuating device 100 is inserted into a valve chamber through the through-hole 1101 in the valve seat 901, the hook 301 of the claw 103 lifts the valve body 901 axially upwards, thereby separating the surface of the valve body 901 from the valve seat 902 and allowing the fluid to flow through the through-hole 1101 in the valve seat 901. As shown in Figures 18, 19, 20 to 21, a liquid container 1800 comprises a container wall 1900 and a bottom-mounted valve 900, which is mounted on the underside of the liquid container 1800 by conventional means. The valve 900 is not provided with a valve actuating device 100. In this embodiment, the valve seat 902 is made of the same material as the container wall 1900 of the liquid container 1800, in order to connect the valve seat 902 to the container wall 1900 of the liquid container 1800 by welding, for example, ultrasonic welding. In this embodiment, the valve body 901 has no closing gap and is made of a material with a density greater than that of water, thus ensuring that it does not float when immersed in water. As shown in Figures 22, 23, 24 to 25, the liquid container 1800 comprises a container wall 1900 and a bottom-mounted valve 900, the valve 900 being mounted with the valve actuating device 100. It can be seen from the figures that the hook 301 of the claw 103 of the valve actuating device 100 can engage with the valve seat surface of the valve seat 902 around the through-opening 1101 in the valve seat 902. Since the hook has a certain height to lift the valve body 901, the valve body 901 and the valve seat 902 form a gap S between them. In this embodiment, the body 101 is provided with a liquid channel 201 through which the liquid can flow.In some other embodiments, the distance between the first plane 401 of the hook 301 and the upper end 102 of the body 101 is greater than the length of the through-hole 1101, and the fluid can flow out of a gap formed between the upper end 102 of the body 101 and the underside of the valve seat 902. It should be noted here that the valve actuating devices shown in the drawings and described in this description are merely some examples of different types of valve actuating devices that can utilize a principle of the present disclosure. It is expressly understood that the principle of the present disclosure is in no way limited to any details or components of the valve actuating devices shown in the drawings or described in this description. A detailed description of several examples of the valve actuation device proposed in the present disclosure has been given above, and a method for opening the valve according to the present disclosure will be explained below by way of example. In conjunction with Figs. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24 to 25, the present disclosure provides a method for opening the valve, wherein the aforementioned valve is mounted at the bottom of a liquid container 1800. Using the aforementioned valve actuating device 100, the valve actuating device 100 is guided in the axial direction of the liquid container 1800 through the through-hole 1101 of the valve seat 902, the valve body 901 is lifted upwards in the axial direction of the liquid container 1800, and the valve body 901 is caused to detach from the valve seat 902, thereby opening the valve 900.This ensures that the valve can be opened from the outside of the liquid container and the liquid inside the container flows out, thus preventing secondary contamination. In use, the valve actuating device 100 is mounted on the valve 900. The valve 900 comprises a valve body 901 and a valve seat 902, the valve seat 902 being provided with a through-opening 1101 and the valve body 901 being arranged on the valve seat 902. The valve actuating device 100 comprises a body 101 and three claws 103. The body 101 has an upper end 102, and the claws 103 are arranged at the upper end 102, so that a human hand can grasp the body 101 and push the valve actuating device 100 upwards from the bottom of the liquid container 1800 in the axial direction of the liquid container 1800.Since the claw 103 comprises a hook 301 and a connecting arm 302, the hook 301 comprising a second chamfer 402, and since the claw 103 is made of a material with a certain degree of elasticity, the claw 103, guided by the second chamfer 402, can engage with the valve seat surface of the valve seat 902 around the through-hole 1101 in the valve seat 902. Since the hook has a certain height for lifting the valve body 901, the valve body 901 cannot be in contact with the valve seat 902, thus forming a gap S through which the fluid can flow. Furthermore, by applying a downward force to the body 101, the claw 103 can be removed from the through-hole, so that the valve body 901 comes into contact with the valve seat 902 and the valve is closed. The valve body 901 also includes a thread on its upper part. The valve body 901 can be rotated relative to the valve seat 902 by pressing on a component with a corresponding helical surface or chamfer, thus creating a way to open the valve from a side facing away from the valve seat. The valve actuating device 100 of the present disclosure does not need to be disassembled after installation in the liquid reservoir 1800. If there is no water in the liquid reservoir, a filter element is installed in the liquid reservoir and then water is added to the liquid reservoir for filtration; and when the filter element needs to be replaced, the water in the liquid reservoir is drained and the filter element is replaced directly. If disassembly is necessary, a configuration of the valve actuating device as shown in Fig. 7 or Fig. 8 can be used. The valve actuating device 100 can be pulled downwards by grasping the body 101 by hand. Guided by the first inclined plane 701 or the chamfer 801, the elasticity of the claw causes the connecting arm 302 to pull the hook 301 towards the center of the valve actuating device, so that the hook 301 can move downwards out of the through-opening 1101 of the valve seat 902 to disassemble the valve actuating device 100 from the valve 900.The valve seat can also be slightly machined; for example, the engagement between the valve seat 902 and the claw 103 can be designed as a chamfer with a specific inclination, the chamfer itself serving as a guide for the hook, thus eliminating the need to provide the first chamfer 701 or the chamfer 801 on the valve actuating device 100. During disassembly, the valve actuating device 100 can be pulled downwards by grasping the body 101 by hand; guided by the chamfer at the engagement point between the valve seat 902 and the claw 103, the elasticity of the claw causes the connecting arm 302 to pull the hook 301 towards the center of the valve actuating device, allowing the hook 301 to move downwards out of the through-hole 1101 of the valve seat 902, thereby disengaging the valve actuating device 100 from the valve 900. As shown in Figs. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24 to 25, the valve actuating device 100 of the present disclosure is mounted on a valve 900 to form a valve. The valve incorporates the valve actuating device 100 of the present disclosure. The valve with the valve actuating device 100 of the present disclosure is mounted on the bottom of the liquid container to form a liquid container which has the aforementioned valve. By means of the method described above for opening the valve of the present disclosure, it can be determined that the valve actuating device of the present disclosure comprises a body and at least one claw. The body is designed to support the claw, and when the valve actuating device is used, the body is held by the hand for actuation. The body has an upper end, and the claw is arranged at the upper end. The claw is connected to the body via the upper end so that actuation of the body by the hand also drives the movement of the claw. The valve actuating device of the present disclosure is mounted on a valve, the valve comprising a valve seat and a valve body, the valve seat being provided with through-holes, and the valve body being arranged on the valve seat.The claw penetrates through the through-holes in the valve seat, causing the valve body to detach from the seat. The body can be manually actuated, thereby driving the claw through the through-hole in the valve seat and lifting the valve body. This separates the valve body from the seat, allowing the liquid to flow out through the gap created after the separation. The device features a simple structure and convenient operation, enabling rapid separation of the valve seat from the valve body. This facilitates smooth liquid drainage within the container, allows the valve to be opened from outside the container, and prevents secondary contamination.Furthermore, the valve actuation device of the present disclosure can be guided from the bottom of the liquid container through the valve seat in the axial direction of the liquid container and lift the valve body upwards in the axial direction of the liquid container to open the valve so that the liquid flows out, which facilitates assembly and disassembly and avoids contact with the interior of the liquid container. In the method for opening the valve proposed in the present disclosure, the valve 900 is mounted at the bottom of the liquid container 1800. The valve 900 comprises the valve seat 902 and the valve body 901, the valve seat 902 being provided with through-openings 1101, and the valve body 901 being arranged on the through-openings 1101. The method comprises: Providing a valve actuating device 100, wherein the valve actuating device 100 comprises a body 101 and at least one claw 103, the body 101 having an upper end 102 and the at least one claw 103 being arranged at the upper end 102; wherein the at least one claw 103 passes from below the liquid reservoir 1800 through the through-opening 1101, so that the valve body 901 is lifted upwards in order to completely or at least partially separate the valve body 901 from the valve seat 902 and thereby open the valve 900; and suspending the body 101 below the valve seat 902 by means of the claw 103.Furthermore, the method may also include exerting a downward force on the body 101 to remove at least one of the claws 103 from the through-hole 1101 and thereby closing the valve 900; and / or rotating the valve body 901 in a horizontal direction relative to the valve seat 902 to open the valve. By using the aforementioned valve actuating device, in which the valve actuating device is guided from the bottom of the liquid container in the axial direction of the liquid container through the through-hole of the valve seat, the valve body is lifted upwards in the axial direction of the liquid container and is caused to separate from the valve seat, the valve is opened. This makes it possible to open the valve from the outside of the liquid container, so that the liquid in the liquid container flows out and secondary contamination is avoided.
