[0033] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] See also Figures 1 to 3 The funnel for filtering the photocurable ceramic slurry comprises a funnel body 1 and a light shield 2.

[0035] The funnel body 1 includes a bucket body 101 and a funnel neck 102, which are integrally formed and used to carry and filter the light-cured ceramic slurry. A filter screen 103 is arranged in the bucket body 1, and the edge of the filter screen 103 is in contact with the inner wall of the bucket body 101. In the utility model, a plurality of strip filter holes are arranged on the filter screen 103. Compared with ordinary mesh filter holes, the strip filter holes can provide a larger filtering area, are easier to clean and maintain during use, and are not easy to cause blockage during the filtering process. In addition, for filtering raw materials with relatively high viscosity such as ceramic slurry, it is more suitable to use long strip filter holes to improve the filtering rate and product yield.

[0036] The light shield 2 can be detachably connected to the top opening of the bucket body 101, thereby blocking the influence of light on the ceramic slurry during the filtering process, preventing the ceramic slurry from absorbing light of the corresponding band for photocuring reaction, thereby causing the slurry to solidify, thereby greatly reducing the filtering effect and even clogging the filter mesh.

[0037] In addition, the funnel for filtering the light-cured ceramic slurry in the present invention further includes a filter screen support 104, see Figure 4 and Figure 5 In one embodiment of the utility model, the filter screen support 104 can be arranged on the upper part of the filter screen 103, or on the lower part of the filter screen 103, or on both the upper part and the lower part of the filter screen 103. Moreover, the filter screen support 104 is arranged to fit the inner wall of the bucket body 101. The filter screen support 104 includes an upper annular support portion 1040 and a lower base portion 1041, and leak holes 105 are formed through the upper annular support portion 1040 and the lower base portion 1041. The upper annular support portion 1040 is used to support the filter screen 103, and the lower base portion 1041 is against the inner wall of the bucket body 101, and the filter screen 103 is limitedly supported according to the inner diameter of the filter screen support 104.

[0038] See also Figure 6 and Figure 7 In one embodiment of the utility model, an annular sealing ring 106 is integrally formed on the outer periphery of the filter screen 103, and the inner sides of the annular sealing rings 106 at the upper and lower ends of the filter screen 103 are provided with internal threads, and the outer peripheries of the bucket body 101 and the light shield 2 are provided with external threads, that is, the aforementioned bucket body 101 and the light shield 2 can be connected by external threads and the internal threads to clamp and fix the filter screen 103.

[0039] In addition, the funnel for filtering the photocurable ceramic slurry also includes a filter screen clamping assembly, which includes a step portion and an end portion of the aforementioned bucket body 101 or light shield 2 that matches the step portion, and the filter screen 103 is clamped between the step portion and the end portion. Specifically, an internal thread is provided on the inner side of the step portion, and an external thread is provided on the outer side of the end portion. The step portion and the end portion are threadedly connected to tighten and fix the filter screen 103.

[0040] See also Figure 8 and Fig. 9 The step portion is arranged on the light shield 2, and the end portion adopts the end portion of the bucket body 101 accordingly. The step portion of the light shield 2 uses the internal thread inside itself to cooperate with the external thread outside the end portion of the bucket body 101, and the thread is tightened to connect, thereby clamping and fixing the filter screen 103.

[0041] See also Fig.10 and Fig.11 The step portion is set on the bucket body 101, and the end portion adopts the end portion of the light shield 2 accordingly. The end portion of the light shield 2 uses the external thread on the outside of itself to cooperate with the internal thread on the inside of the step portion of the bucket body 101, and the thread is tightened to connect, thereby clamping and fixing the filter screen 103.

[0042] In another embodiment of the present invention, refer to Fig.12 and Fig.13 The filter screen clamping assembly also includes: a flange ring formed on the outer periphery of the filter screen 103, an upper flange ring edge is provided on the light shield 2, and a lower flange ring edge is provided on the bucket body 101. The upper flange ring edge, the lower flange ring edge and the flange ring are provided with a plurality of through holes, and the through holes are used to accommodate the fixing pins 3, so as to achieve the fixing and support of the filter screen. A flange sealing ring is provided between the upper flange ring edge and the lower flange ring edge and the flange ring to prevent the slurry from flowing out of the funnel through the gap of the flange ring, resulting in slurry loss.

[0043] In summary, the funnel used for filtering photocurable ceramic slurry in the utility model adopts a light shield to prevent the photocurable ceramic slurry from being irradiated by light during filtering, thereby preventing the photocurable ceramic slurry from being contaminated by a photocuring reaction. In addition, the strip-shaped filter mesh is provided to accelerate the filtering speed of the photocurable ceramic slurry and reduce the residue of the slurry on the surface of the filter. At the same time, the various parts of the funnel can be detachably connected, and are convenient to separate and clean after use. In addition, the utility model is also provided with a variety of different filter connection support components for fixing and supporting the filter.
