When the flexible filter screen is fitted on the filter screen frame, the flexible filter screen can be positioned by passing the positioning posts 2160 on the filter screen frame through the corresponding positioning holes 2220 of the flexible filter screen.

[0037] As an example, in the above filter basket, a clamping member can also be included, which clamps the upper edge and / or the lower edge of the flexible filter screen on the top frame and / or the bottom frame, respectively.

[0038] Figure 3C The structure of the filter basket 20 including the clamping member is shown as an example. As Figure 3C shown, the filter basket 20 includes a first clamping member 2310, wherein the first clamping member 2310 clamps the upper edge of the flexible filter screen 220 on the top frame of the filter screen frame 210. As Figure 3C further shown, the filter basket 20 can also include a second clamping member 2320, wherein the second clamping member 2320 clamps the lower edge of the flexible filter screen 220 on the bottom frame of the filter screen frame 210.

[0039] According to embodiments of the present disclosure, unlike the structure shown in Figure 3C , the clamping member can be formed in an integral structure with the flexible filter screen, and when the flexible filter screen is fitted on the filter screen frame, the upper / lower edge of the flexible filter screen is clamped on the top / bottom frame of the filter screen frame by the clamping member. As Figure 2AAs shown, a clamping member 2180 is integrated at the upper edge of the flexible filter screen 220, and when the flexible filter screen 220 is sleeved on the filter screen frame 210, the upper edge of the flexible filter screen 220 can be clamped with the top frame 2120 of the filter screen frame 210 through the clamping member 2180.

[0040] As an example, the clamping member includes at least one of the following: a rubber ring, a metal ring, a plastic ring, or an elastic band.

[0041] As an example, Figure 4 The partial details of another filter screen frame are schematically shown. As Figure 4 As shown, a positioning groove 2140 is provided at the top frame 2120 of the filter screen frame, and by correspondingly providing a protrusion at the upper edge of the flexible filter screen, when the flexible filter screen is sleeved on the filter screen frame, the upper edge of the flexible filter screen can be positioned by the protrusion provided at the upper edge of the flexible filter screen clamping into the positioning groove on the filter screen frame, for example, a rubber ring can be provided at the upper edge of the filter screen, and a circle of protrusions is provided inside the rubber ring, and the protrusions are clamped into the positioning groove on the filter screen frame to position.

[0042] Although the positioning groove is shown at the top frame 2120 of the filter screen frame 210, Figure 4 however, as another example, the positioning groove can also be provided at the bottom frame of the filter screen frame 210, and a protrusion is correspondingly provided at the lower edge of the flexible filter screen, so that the flexible filter screen is positioned by the protrusion clamping into the positioning groove, for example, a rubber ring can be provided at the lower edge of the filter screen, and a circle of protrusions is provided inside the rubber ring, and the protrusions are clamped into the positioning groove at the bottom frame of the filter screen frame to position.

[0043] In addition, for the structure of the filter screen frame shown in Figure 4 to increase the connection fastness between the flexible filter screen and the filter screen frame, a clamping member can also be used to clamp the flexible filter screen, similar to the structure shown in Figure 3C that is, the upper edge and / or the lower edge of the flexible filter screen is clamped on the top frame and / or the bottom frame of the filter screen frame by the clamping member.

[0044] Of course, for the structure of the filter screen frame shown in Figure 4 the form of the clamping member shown in Figure 3C that is, the protrusions provided at the upper edge and / or the lower edge of the filter screen respectively form an interference fit with the positioning grooves correspondingly provided at the top frame and / or the bottom frame of the filter screen frame, so that the connection between the flexible filter screen and the filter screen frame is more reliable.

[0045] Optionally, the filter screen is detachably connected to the filter screen frame by a connecting member. The filter screen can be arranged outside the filter screen frame or inside the filter screen frame and is connected to the filter screen frame by means such as elastic ropes, laces, elastic flanges or clamping members.

[0046] For example, in the filter basket, the thickness of the filter screen is 3-15 mm, and the mesh diameter of the filter screen is not greater than 100 um, so that fine particles such as dust can be filtered out, achieving the purpose of deep cleaning the pool.

[0047] Optionally, in the filter basket, the filter screen is made of polyester fiber.

[0048] Optionally, as shown in Figure 2A and Figures 5A-5B In the filter basket, a handle 2190 is arranged on the filter screen frame to facilitate the removal of the filter basket, thereby cleaning the garbage / pollutants trapped in the filter basket.

[0049] Optionally, in the filter basket, a second opening is arranged at the lower part of the cavity to allow water flow to flow into the cavity.

[0050] According to the embodiments of the present disclosure, since the flexible filter screen is detachably mounted to the filter screen frame, the filter screen frame can be repeatedly used while the flexible filter screen is used as a consumable.

[0051] According to another aspect of the present disclosure, a two-stage filter for a pool automatic cleaning device is provided, which includes the above-mentioned filter basket as a first-stage filter and an outer filter basket as a second-stage filter. The filter basket can be placed inside the outer filter basket, and the filtering accuracy of the filter basket is greater than that of the outer filter basket.

[0052] According to the two-stage filter of the embodiment of the present disclosure, since the filtering aperture of the inner filter basket as the first-stage filter is smaller than the filtering aperture of the filtering screen of the outer filter basket as the second-stage filter (i.e., the filtering precision of the inner filter basket as the first-stage filter is higher than the filtering precision of the outer filter basket as the second-stage filter), the filtering of the inner filter basket is more precise than that of the outer filter basket, and can filter out smaller dirt particles. In addition, since the inner filter basket is detachably installed into the outer filter basket, depending on actual needs, for example, when more precise filtering of the water body of the pool is needed, i.e., when smaller dirt particles need to be filtered out, the filter basket according to the embodiment of the present disclosure can be installed into the outer filter basket, so as to filter out smaller dirt particles via the filtering screen with smaller filtering aperture. When there is no such need, the water body can be filtered only by the filtering screen of the outer filter basket without installing the inner filter basket. In this way, the applicability flexibility of the filter for different filtering needs is improved.

[0053] Optionally, in the two-stage filter described above, the bottom of the outer filter basket is provided with a water inflow port.

[0054] According to still another aspect of the present disclosure, a pool automatic cleaning device is provided, comprising the two-stage filter described above; wherein the two-stage filter is detachably installed in the pool automatic cleaning device.
