A: A straw type temperature sensing cup, comprising a cup body and a cup cover (1). The cup cover (1) is provided with an upper cover body (11) and a lower cover body (12) hinged to the upper cover body (11); the lower cover body (12) is provided with a straw, and a cavity (121) is formed in the lower cover body (12); a temperature sensor, a digital display (122), a chip (123), and a battery are provided in the cavity (121); a touch surface cover (13) is provided at the top of the lower cover body (12), and a temperature sensing surface cover (14) is provided at the bottom; a temperature sensor probe is in contact with the temperature sensing surface cover (14). The straw type temperature sensing cup has a temperature display function, and it is easy to clean the bottom of the cover body; moreover, the temperature sensing surface cover (14) has a high melting point and is not easily decomposed at high temperature.
B: A filter cup, filter paper, and a pour-over coffee pot kit provided with the filter cup and the filter paper. The filter cup (10) comprises a cup body (12). The filter paper (30) can be placed on the inner side of the cup body (12). The cup body (12) comprises an accommodation chamber (123) defined by the inner side wall of the cup body (12) in a surrounding wall, at least one through hole (122) formed in the bottom of the accommodation chamber (123), and a filtering supporting component (124) disposed above the at least one through hole (122) and protruding towards the direction of the direction of the accommodation chamber (123). A connecting channel is disposed between the filtering supporting component (124) and the at least one through hole (122). The filter paper (30) is sleeved on the periphery of the filtering supporting component (124). The filter paper (30) is used for the filter cup (10), and comprises a folded skirt hem (31) formed by means of a folding, a filtering chamber (32) defined by the folded skirt hem (31) in a surrounding manner, and a raised block (33) formed at the bottom of the filtering chamber (32). The raised block (33) is a bump formed by the top of the filter paper (30) and sleeved on the periphery of the filtering supporting component (124). The pour-over coffee pot kit comprises the filter cup (10), the filter paper (30), and a pot body (30) disposed at the bottom end of the filter cup (10). By sleeving the raised block (33) on the periphery of the filtering supporting component (124), the taste is improved.
C: A cooking cup (100) and a cooking machine (200) using the cooking cup (100). The cooking cup (100) comprises a capacity cup (30) and a cup lid (10) used for covering the capacity cup (30); the capacity cup (30) comprises a cup body (31); a stirring assembly is provided in the cup body (31); the top edge of the cup body (31) protrudes outwards to form at least two flanges (312); the cup lid (10) comprises a roofing (11) used for covering the capacity cup (30) and a lid rim (12) extending downwards from the edge of the roofing (11); the lid rim (12) extends inwards to form at least two pawls (121) snap-fit to the flanges (312) by means of rotating. When the cup lid (10) covers the capacity cup (30), the cup lid (10) is rotated to drive the pawls (121) to move below corresponding flanges (312), so that the flanges (312) and the pawls (121) are hooked to each other. By fixing the cup lid (10) on the capacity cup (30), the cup lid (10) can be prevented from being driven out when the pressure in the capacity cup (30) increases, and the safety is high.
