a cover plate, located on the touch functional layer; and
an anti-dazzle layer, the anti-dazzle layer being disposed between the touch functional layer and the cover plate, and the anti-dazzle layer being configured to scatter light incident on the anti-dazzle layer,
wherein a reflectivity of the cover plate is greater than a light transmittance of the cover plate, a haze of the anti-dazzle layer is in a range of 8%-25%, and a light transmittance of the anti-dazzle layer is in a range of 85%-98%.

2. The touch device according to claim 1 , wherein the anti-dazzle layer comprises a base layer and a plurality of convex parts, the plurality of convex parts are at least disposed at a side of the base layer facing towards the cover plate.

3. The touch device according to claim 2 , wherein the base layer comprises a first surface facing towards the cover plate and a second surface facing towards the touch functional layer, and the plurality of convex parts are disposed on only the first surface of the base layer.

4. The touch device according to claim 3 , further comprising:
a first adhesive layer, disposed between the anti-dazzle layer and the cover plate and configured to adhere the anti-dazzle layer with the cover plate; and
a second adhesive layer, disposed between the anti-dazzle layer and the touch functional layer and configured to adhere the anti-dazzle layer with the touch functional layer.

5. The touch device according to claim 4 , wherein the first surface of the base layer is provided with the plurality of convex parts, the first adhesive layer is disposed on the first surface of the base layer, and an orthographic projection of the first adhesive layer on the base layer has no overlap with orthographic projections of the plurality of convex parts on the base layer.

6. The touch device according to claim 5 , wherein the second surface of the base layer is provided with the plurality of convex parts, the second adhesive layer is disposed on the second surface of the base layer, and an orthographic projection of the second adhesive layer on the base layer has no overlap with orthographic projections of the plurality of convex parts on the base layer.

7. The touch device according to claim 5 , wherein the second surface of the base layer is not provided with the convex part, and the second adhesive layer is disposed on an entirety of the second surface of the base layer.

8. The touch device according to claim 2 , wherein the base layer comprises a first surface facing towards the cover plate and a second surface facing towards the touch functional layer, and the plurality of convex parts are disposed on the first surface and the second surface of the base layer.

9. The touch device according to claim 2 , wherein the plurality of convex parts are located at a position of the base layer where corresponds to a position of the touch functional layer where a rainbow stripe is to be presented.

10. The touch device according to claim 2 , wherein the convex part is of a core-shell structure, and a refractive index of a material of the core-shell structure is gradually increased from the core to the shell.

11. The touch device according to claim 10 , wherein the convex part comprises: a first material layer, a second material layer enveloping the first material layer, and a third material layer enveloping the second material layer, and the first material layer is closer to the base layer than both the second material layer and the third material layer to the base layer.

12. The touch device according to claim 11 , wherein a refractive index of the first material layer is in a range of 1.15-1.45, a refractive index of the second material layer is in a range of 1.25-1.55, and a refractive index of the third material layer is in a range of 1.35-1.65.

13. The touch device according to claim 1 , wherein the touch functional layer comprises a base material layer, and the base material layer comprises a material with birefringence effect.

14. The touch device according to claim 1 , wherein a material of the convex part is selected from a group consisting of silicon oxide, titanium dioxide, cerium fluoride, sodium hexafluoro aluminate, aluminium sesquioxide, hafnium oxide, calcium fluoride, magnesium fluoride, magnesium oxide, zirconium oxide, praseodymium fluoride, scandium oxide, lanthanum fluoride, barium fluoride, and yttrium fluoride.

15. The touch device according to claim 1 , wherein a material of the base layer is selected from a group consisting of triacetate fiber and cyclo olefin polymer.

16. An intelligent mirror, comprising:
a touch device, comprising:
a touch functional layer, configured to sense an occurrence of touch;
a cover plate, located on the touch functional layer; and
an anti-dazzle layer, the anti-dazzle layer being disposed between the touch functional layer and the cover plate, and the anti-dazzle layer being configured to scatter light incident on the anti-dazzle layer;
a display module, the display module being disposed at a side of the touch functional layer away from the anti-dazzle layer,
wherein a reflectivity of the cover plate is greater than a light transmittance of the cover plate, a haze of the anti-dazzle layer is in a range of 8%-25%, and a light transmittance of the anti-dazzle layer is in a range of 85%-98%.

17. A manufacturing method of a touch device, comprising:
forming a touch functional layer, the touch functional layer being configured to sense an occurrence of touch;
