[0023] Embodiment 1:

[0024] See also Figures 1 to 4 The embodiment of the utility model provides a water purification filter element, which is mainly used to extend the overall service life of the filter element. The water purification filter element includes two support sections 1, which are used to form a rotational connection with the installation part to achieve overall support. A folding section 2 is rotatably installed between the two support sections 1. The folding section 2 uses an existing filter screen, which can be an activated carbon layer, a mesh layer or a non-woven fabric layer, etc. It is an existing mature technology and will not be described in detail here.

[0025] A water hole 3 is provided on the surface of the folding section 2 for water to pass through. When the water passes through the folding section 2, the water is filtered by the folding section 2 so that the impurities are filtered out, and the clean water can pass through the water hole 3 normally. It should be noted that the impurities here refer to particles of a certain size, rather than microscopic impurities.

[0026] In order to achieve the overall installation, such as Figure 4 As shown, the water purification filter element also includes a shell 4 for movably mounting two support sections 1, that is, the support section 1 can be relatively fixed in the shell 4, and the support section 1 can rotate based on the shell 4, thereby driving the folding section 2 to rotate synchronously.

[0027] In order to ensure the folding section 2 to purify water, the outermost edge of the folding section 2 is in contact with the inner wall of the shell 4, so that water can only flow down through the folding section 2 after entering the shell 4.

[0028] In order to ensure that water can only flow down through the folding section 2, a water inlet pipe 5 connected to an external water supply mechanism is fixedly connected to the surface of the housing 4, and the end of the water inlet pipe 5 can extend into the housing 4 and correspond to the position of the folding section 2 away from the outermost edge; when the water supply mechanism discharges water into the housing 4 through the water inlet pipe 5, the water flow can reach the folding section 2 near the center. Among them, the water supply mechanism is an existing mature technology and will not be described in detail here.

[0029] When in use, water flows into the shell 4 through the water inlet pipe 5 and falls to the position above the folding section 2. The water can flow down through the water hole 3 to be purified, while the debris is blocked by the folding section 2 and slides down along the folding section 2. The continuous water outflow of the water inlet pipe 5 can accelerate the sliding of the debris, so that the debris falls between the folding section 2 and the inner wall of the shell 4.

[0030] After using it for a period of time, the handle can be turned to drive the upper support section 1 to rotate, and the upper support section 1 can drive the folding section 2 to rotate synchronously, thereby changing the corresponding position of the folding section 2 and the water inlet pipe 5 to ensure a long-term and effective water purification effect. After using it for a period of time, the upper support section 1 can be pulled by the handle, and the support section 1 drives the folding section 2 to move synchronously, so that the outermost edge of the folding section 2 is separated from the inner wall of the shell 4, so that the debris falls onto the inner bottom wall of the shell 4 through the gap between the folding section 2 and the inner wall of the shell 4.

[0031] To sum up, through the coordination of structures such as the folding section 2, the shell 4, the supporting section 1 and the water hole 3, effective filtration of the water flow and effective collection of debris can be achieved, the corresponding position of the folding section 2 and the water inlet pipe 5 and the relative position of the folding section 2 and the inner wall of the shell 4 can be quickly adjusted, and the adjustment is not affected by the water inlet and water outage of the water inlet pipe 5, which can ensure the long-term effective filtering effect of the folding section 2 on the water flow; the overall operation is simple, and the adjustment can be achieved by simple rotation and pulling, which is more practical.

[0032] Embodiment 2:

[0033] See also Figures 1 to 5 On the basis of the first embodiment, the folding section 2 includes a plurality of upper inclined sections 201 and lower inclined sections 202 that are rotatably connected in sequence, and the adjacent upper inclined sections 201 and lower inclined sections 202 that form the outermost edges after being combined can be integrally formed; the uppermost upper inclined section 201 is rotatably connected to the upper support section 1, and the lowermost lower inclined section 202 is rotatably connected to the lower support section 1, so as to achieve effective support of the whole. The intersection of the upper inclined section 201 and the lower inclined section 202 abuts against the inner wall of the housing 4, and the water hole 3 can penetrate the upper inclined section 201 and the lower inclined section 202, so as to achieve the flow of water through the folding section 2.

[0034] In this embodiment, a plurality of water inlet pipes 5 are provided, and their number corresponds to the number of upper inclined portions 201. The position where the water inlet pipes 5 extend into the shell 4 corresponds to the position close to the upper part of the upper inclined portion 201, so that the water flow can flow downward through the water hole 3 without overflowing from the inner wall of the shell 4 and escaping purification.

[0035] In order to speed up the speed of water flowing down after purification, the water hole 3 can pass through all the upper inclined parts 201 instead of being opened on the lower inclined part 202. At this time, when the water flows through the lower inclined part 202 and flows into the interior of the folding section 2, it will no longer flow out through the lower inclined part 202, but will flow down quickly along the funnel-shaped lower inclined part 202.

[0036] In order to achieve quick disassembly and assembly as well as later replacement of the whole, adjacent upper inclined parts 201 and lower inclined parts 202 can be connected by threads, so that the upper inclined parts 201 and lower inclined parts 202 corresponding to a part can be disassembled as needed without affecting the overall use.

[0037] In order to realize the rotation of the folding section 2 in the shell 4, a handle (not shown in the figure) can be fixedly installed on the outer surface of the upper support section 1; the handle can also be used to pull the support section 1 in the up and down directions, and the handle can prevent the upper support section from falling into the inside of the shell 1 due to gravity.

[0038] When in use, water flows into the shell body 4 through the water inlet pipe 5 and falls to the upper position of the upper inclined portion 201. The water can flow down through the water hole 3 to be purified, while the debris is blocked by the upper inclined portion 201 and slides down along the inclined upper inclined portion 201. Even if there are parts that have not slid down, they can be flushed away and slide down under the action of continuous water discharge from the subsequent water inlet pipe 5. The debris that slides down is concentrated between the top of the upper inclined portion 201 and the inner wall of the shell body 4.

[0039] After using it for a period of time, the handle can be turned to drive the upper support section 1 to rotate, and the upper support section 1 can drive the folding section 2 to rotate synchronously, thereby changing the corresponding position of the upper inclined portion 201 and the water inlet pipe 5 to ensure a long-term and effective water purification effect. After using it for a period of time, the upper support section 1 can be pulled by the handle, and the support section 1 drives the upper inclined portion 201 and the lower inclined portion 202 to move synchronously, so that the outermost edge of the folding section 2 is separated from the inner wall of the shell 4 (the angle between the upper inclined portion 201 and the lower adjacent inclined portion 202 becomes larger), and at this time, the debris filtered by the upper inclined portion 201 can automatically slide down and fall onto the inner bottom wall of the shell 4. The above adjustment process can be carried out both during the water discharge process of the water inlet pipe 5 and during the water stop process of the water inlet pipe 5.

[0040] In order to quickly handle the fallen debris, the inner bottom wall of the housing 4 may have a slope, which is designed in an overall figure eight shape (similar to the upper slope 201) inside the housing 4. When the debris falls on the inner bottom wall of the housing 4, it will be automatically gathered by the slope. An opening connected to the slope may be provided at the bottom of the housing 4 to facilitate the discharge of the debris.

[0041] To sum up, through the coordination of the upper inclined portion 201, the lower inclined portion 202, the support section 1, the handle and other structures, effective filtration of the water flow and effective collection of debris can be achieved. During use, the corresponding positions of the upper inclined portion 201 and the water inlet pipe 5 can be freely adjusted, thereby ensuring the long-term effective filtering effect of the upper inclined portion 201 on the water flow. The overall operation is simple, and the adjustment can be achieved by simply turning and pulling, and it can be freely adjusted both when the water is stopped and when the water is in, and it has stronger applicability.
