This is only for the 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. Therefore, it should not be understood as a limitation on the present invention.

[0037] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0038] Based on the problem pointed out in the background art that the filter bottle and the valve head in the existing water purifier are easy to loosen after being sealed and connected, the present invention provides a filtering device, which aims to prevent the filter bottle and the valve head from loosening through an independent limiting component respectively cooperating with the filter bottle and the valve head, thereby improving the stability of the connection between the filter bottle and the valve head.

[0039] Specifically, Figures 1 to 5 As shown, the filtering device of the present invention comprises a filter bottle 1, a valve head 2 and an insertion rod 3, wherein the filter bottle 1 is provided with a groove 11, the valve head 2 is provided with a through hole 22, the valve head 2 is sealed and connected with the filter bottle 1, and when the installation is completed, the insertion rod 3 is respectively plugged and matched with the groove 11 and the through hole 22 to prevent the filter bottle 1 from being separated from the valve head 2. Specifically, a cover body 21 is provided on the valve head 2, and when the filter bottle 1 and the cover body 21 are connected in place, the through hole 22 corresponds to the groove 11, and the insertion rod 3 passes through the through hole 22 and enters the groove 11 to prevent the end of the filter bottle 1 from being separated from the cover body 21.

[0040] More specifically, if Figure 3 , Figure 4 as well as Figure 5 As shown, the groove 11 of the outer wall of the upper end of the filter bottle 1 of the present invention is an annular groove, the cover body 21 below the valve head 2 and sealed with the upper end of the filter bottle 1 is a circular cover body 21, and the through hole 22 of the side wall on the cover body 21 includes a first through hole 221 and a second through hole 222. When the rod 3 is inserted into the first through hole 221 and the second through hole 222 in the horizontal direction, the middle part of the rod 3 is located in the annular groove 11, thereby preventing the upper end of the filter bottle 1 from escaping from the cover body 21 of the valve head 2 in the vertical direction.

[0041] It should be noted that, although the above description is that the insertion rod 3 is plugged into the filter bottle 1 and the cover body 21, the protection scope of the present invention is not limited to the above situation. Without departing from the principle of the present invention, those skilled in the art can adjust the specific forms of the insertion rod 3, the groove 11, the through hole 22 and the matching mode therebetween.

[0042] Specifically, as a limiting member, the plug rod 3 can be set in other forms, and correspondingly, the groove 11 and the through hole 22 can be set in the form of other limiting structures. For example, the plug rod 3 can be set in two rows, the through hole 22 and the groove 11 are staggered in height, one or two plug rods 3 in the upper row are inserted into the through hole 22 of the cover body 21, and one or two plug rods 3 in the lower row are inserted into the groove 11 of the filter bottle 1, or the outer wall of the filter bottle 1 and the cover body 21 are both provided with a groove structure, one or two plug rods 3 in the upper row are inserted into the groove structure of the cover body 21, and one or two plug rods 3 in the lower row are inserted into the groove structure of the filter bottle 1. Such adjustments and changes to the specific forms of the plug rod 3, the groove 11, the through hole 22 and their matching methods do not deviate from the principles of the present invention, and therefore will fall within the scope of protection of the present invention.

[0043] Continue reading Figure 3 and Figure 5 In a preferred embodiment, the insertion rod 3 is a U-shaped rod, and the number of the through holes 22 is two. The two through holes 22 are symmetrically distributed along the horizontal direction of the cover body 21, and the two through holes 22 correspond to the two ends of the insertion rod 3 respectively.

[0044] like Figure 3 and Figure 5 As shown, the insertion rods 3 at both ends of the U-shaped rod are respectively inserted into the through holes 22 on both sides of the cover body 21, and enter the annular groove 11 at the upper end of the filter bottle 1. Therefore, the insertion rod 3 can limit the filter bottle 1 and the cover body 21 from both sides. When the filter bottle 1 or the valve head 2 is subjected to external force and causes the two to rotate relative to each other, the middle part of the insertion rod 3 is always located in the annular groove 11, ensuring the stability of the connection between the filter bottle 1 and the valve head 2.

[0045] Preferably, if Figure 5As shown, the insertion rod 3 is provided with a handle 30, which is located at the bottom of the U-shaped rod. In addition, the handle 30 and the bottom of the U-shaped rod form a closed "mouth"-shaped structure, which is convenient for the user to grasp and operate the insertion rod 3.

[0046] It should be noted that the shape of the handle 30 is not limited to the above structure. According to actual needs, the handle 30 can be set to a T-shaped structure or an L-shaped structure, etc. Such adjustment and change of the shape of the handle 30 does not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention.

[0047] Continue reading Figure 3 and Figure 5 A positioning protrusion 23 is provided on the outer wall of the cover body 21, a first pin hole 231 is provided on the positioning protrusion 23, a second pin hole 31 is provided on the insertion rod 3, and the filtering device of the present invention also includes a columnar member 4. In the assembled state, the columnar member 4 is inserted into the first pin hole 231 and the second pin hole 31 to prevent the insertion rod 3 from moving relative to the cover body 21.

[0048] Specifically, Figure 3 and Figure 5 As shown, when the plug rod 3 limits the filter element 1 and the valve head 2 in the horizontal direction, the second pin hole 31 located in the middle position of the plug rod 3 is aligned with the first pin hole 231 of the positioning protrusion 23 located on the cover body 21 in the vertical direction, and the columnar member 4 can be inserted into the first pin hole 231 and the second pin hole 31, thereby fixing the plug rod 3 on the cover body 21.

[0049] Next Read Figure 6 The columnar component 4 includes a pin 41 and a countersunk handle 42 connected to one end of the pin 41. The directions of the first pin hole 231 and the second pin hole 31 are the same as the length direction of the filter bottle 1. When the filter bottle 1 is installed upright, the pin 41 is located in the first pin hole 231 and the second pin hole 31, and the countersunk handle 42 relies on its own gravity to prevent the pin 41 from escaping from the first pin hole 231 and the second pin hole 31.

[0050] It should be noted that, although the locking structure of the insertion rod 3 and the cover body 21 is described above as a structure in which the columnar member 4 and the first pin hole 231 and the second pin hole 31 are plugged into each other, this is not restrictive, and those skilled in the art may also adopt other structures to lock the insertion rod 3 and the cover body 21 without departing from the principle of the present invention. For example, a hook may be provided on the outer wall of the cover body 21, and when the insertion rod 3 is plugged into place, the hook may be used to clamp the bottom end of the U-shaped insertion rod 3, thereby fixing the insertion rod 3 on the cover body 21.

[0051] In addition, under the premise of being locked by plugging with the first pin hole 231 and the second pin hole 31, the columnar member 4 can also be set in other structural forms besides the L-shape, as long as it includes a pin plugged with the first pin hole 231 and the second pin hole 31. For example, the columnar member 4 can also be set in the form of a bolt, a screw, etc.

[0052] Continue reading Figure 2 and Figure 4 The filtering device of the present invention further comprises an annular sealing ring 5, which is located in the annular sealing groove 12 at the end of the filter bottle 1. In the assembled state, the annular sealing ring 5 is in sealing contact with the inner wall of the cover body 21.

[0053] For example, Figure 2 and Figure 4 As shown, there are two annular sealing rings 5, and two parallel annular sealing grooves 12 are provided on the circumference of the upper end of the filter bottle 1. The annular sealing grooves 12 are arranged close to the groove 11, and the two annular sealing rings 5 ​​are sleeved in the two annular sealing grooves 12, that is, the annular sealing rings 5 ​​are fixed in the annular sealing grooves 12. When the upper end of the filter bottle 1 and the cover body 21 are installed, the two annular sealing rings 5 ​​are in sealing contact with the inner side wall of the cover body 21 to prevent water from leaking out from the gap between the outer side wall of the filter bottle 1 and the inner side wall of the cover body 21.

[0054] It should be noted that the number of annular sealing rings 5 ​​is not limited to two. According to actual needs, the number of annular sealing rings 5 ​​can be set to one or more than two. Such adjustment and change of the number of annular sealing rings 5 ​​does not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention.

[0055] The assembly process of the filter bottle 1 and the valve head 2 is as follows: the cover body 21 at the lower end of the valve head 2 is sleeved on the upper end of the filter bottle 1, so that the inner wall of the cover body 21 is in close contact with the annular sealing ring 5 at the upper end of the filter bottle 1, and the through holes 22 on both sides of the cover body 21 correspond to the annular grooves 11 on the filter bottle 1. The handle 30 is held to push the plug rod 3 so that the two ends of the plug rod 3 are respectively inserted into the through holes 22 on both sides, that is, the end of the plug rod 3 enters the first through hole 221 and passes through the groove 11 and finally passes through the second through hole 222. At this time, the middle part of the plug rod 3 is located in the groove 11, so that the filter bottle 1 and the valve head 2 are clamped and fixed. Continue to hold the handle 30 and move the rod 3 so that the second pin hole 31 on the rod 3 is aligned with the first pin hole 231 on the positioning protrusion 23. At the same time, the pin 41 of the columnar component 4 can pass through the second pin hole 31 and the first pin hole 231 from top to bottom by relying on the weight of the countersunk handle 42. The columnar component 4 locks the rod 3 on the cover body 21 of the valve head 2.

[0056] Finally, the present invention also provides a water purification device, which includes the above-mentioned filtering device.

[0057] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, 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 fall within the protection scope of the present invention.
