[0025] To make the purpose, technical scheme and advantages of the present application more clear, specific embodiments will be described below in conjunction with the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present application. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present application.

[0026] The heating disc bottom disc structure provided by the present application comprises a bottom disc body 1, and a plurality of hollow structure bosses 101 are formed on the surface of the bottom disc body 1 from the inner side to the outer side.

[0027] In some embodiments, the upper end surface of the boss 101 is a smooth plane.

[0028] Specifically, in order to ensure the strength of the heating disc bottom disc structure, a plurality of convex ribs are arranged on the surface of the heating disc bottom disc, which causes the suction disc to be unable to directly adsorb the heating disc bottom disc and unable to perform mechanized operation. After the boss 101 is arranged, the upper end surface of the boss 101 is a smooth plane, which is beneficial to the suction disc adsorbing the boss 101 to form negative pressure suction to the heating disc bottom disc.

[0029] Specifically, the shape of the boss 101 can be various, such as circular, square or strip-shaped, etc.

[0030] Preferably, the circular structure is selected as the boss 101, which facilitates the alignment of the circular suction disc to the entire bottom disc body 1.

[0031] Specifically, when the heating plate generates heat, hot air will accumulate in the boss 101, and the heat of the hot air will be conducted to the surface of the bottom disc body 1, avoiding the rapid conduction of heat to the surface of the heating disc bottom disc and then the rapid dissipation to the outside, causing heat loss and low heat utilization efficiency.

[0032] Preferably, the present application further comprises a plurality of first type convex points 102 arranged at the positions other than the boss 101, which are protruded from the inner side to the outer side, and also play the role of improving the structural strength of the heating disc bottom disc and assisting in improving the heat efficiency.

[0033] Further, the present application further comprises a plurality of second type convex points 103 arranged on the surface of the bottom disc body 1, which are arranged at the positions other than the boss 101 and the first type convex points 102, are protruded from the inner side to the outer side, and specifically, the second type convex points 103 are in a hollow circular structure.

[0034] Specifically, the areas of the boss 101, the first type of bump 102 and the second type of bump 103 gradually decrease from large to small. The boss 101 with large area plays a role of mainly improving the structural strength of the heat disc bottom plate and improving the heat utilization efficiency. The first type of bump 102 and the second type of bump 103 play a role of assisting in enhancing the structural strength of the heat disc bottom plate and assisting in improving the heat utilization efficiency.

[0035] Preferably, the plurality of bosses 101 are arranged in a direction around the center of the bottom plate body 1, can gather heat in multiple directions and uniformly transmit heat outward, and ensure that the surface temperature of the entire bottom plate body 1 is uniform.

[0036] Preferably, the boss 101 is a circular structure and the diameter is at least 15 mm. The boss 101 with large area is conducive to heat gathering but is not conducive to enhancing the structural strength of the bottom plate body 1. Therefore, the heat can be fully gathered while ensuring sufficient structural strength.

[0037] Preferably, the depth h of the boss 101 is set to 0 < h ≤ 3 mm. In the case of ensuring that heat can be gathered in a large area, the depth of the boss 101 is not too large, so that heat is difficult to conduct outward.

[0038] It should be understood that the above specific embodiments of the present application are only used for illustrative or explanatory purposes of the principles of the present application, and do not constitute a limitation on the present application. Therefore, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present application shall be included in the protection scope of the present application. In addition, the appended claims of the present application are intended to cover all variations and modifications falling within the scope and boundary of the appended claims, or the equivalent forms of such scope and boundary.
