[0026] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The utility model discloses a heater. The utility model fixes an inner tube 2 on a base 1. A heating element is arranged in the inner tube 2. A heat dissipation hole 1 and a heat dissipation hole 2 4 are respectively opened on the upper end and the side wall of the inner tube 2. The heat dissipation hole 1 3 and the heat dissipation hole 2 4 on the inner tube 2 can limit the heat dissipation area of ​​the heating element, that is, the upper part and the outer peripheral side of the inner tube 2 can achieve effective heat dissipation, thereby improving the heating effect.

[0028] By designing the outer mesh cover 5, the outer mesh cover 5 can prevent external objects or people from contacting the inner cylinder 2, thereby preventing fire or burns;

[0029] The upper end wall of the inner tube 2 is evenly recessed downward to form a plurality of grooves 7, and a heat dissipation hole 3 is provided on the inner side wall of each groove 7. The plurality of heat dissipation holes 3 can improve the efficiency of the heater in dissipating heat upward. In addition, the design of the grooves 7 can prevent impurities or dust on the top of the outer mesh cover 5 from falling directly into the inner tube 2.

[0030] Embodiment 1

[0031] See attached Figure 1-4 The utility model is a schematic diagram of the overall and partial structures of an embodiment of the utility model. The utility model specifically discloses a heater, including:

[0032] Base 1, the circular base 1 is arranged horizontally, and an adjustment switch 10 is embedded on the side wall of the base 1;

[0033] The inner cylinder 2 is made of metal material and has a circular cross-sectional outer contour. The inner cylinder 2 is arranged vertically. An upwardly convex annular metal cover is coaxially fixed to the lower end of the inner cylinder 2. The annular metal cover is fixed to the upper end of the base 1 by bolt connection; the upper end of the inner cylinder 2 is closed, and the upper end wall of the inner cylinder 2 is evenly recessed downward to form a plurality of grooves 7. A heat dissipation hole 3 is provided on the inner side wall of each groove 7. In this embodiment, the center line of the groove 7 in the groove length direction is arc-shaped, and the plurality of grooves 7 are evenly arranged along the circumference of the upper end wall of the inner cylinder 2. Due to the design of the grooves 7, while ensuring the heat dissipation effect, impurities or dust above the outer mesh cover 5 will not fall directly onto the heating wire 9; a plurality of heat dissipation holes 2 4 are evenly distributed on the side wall of the inner cylinder 2. The heat dissipation holes 2 4 are circular or polygonal. In this embodiment, the heat dissipation holes 2 4 are circular;

[0034] The heating element is fixed to the bottom of the inner tube 2, and the heating element can dissipate heat to the upper end and the outer peripheral side of the inner tube 2 through the heat dissipation hole 1 3 and the heat dissipation hole 2 4;

[0035] The outer mesh cover 5 made of high temperature resistant material is buckled on the upper end of the base 1, and the inner tube 2 and the heating element are both located inside the outer mesh cover 5. The outer mesh cover 5 mainly plays a protective role, on the one hand, preventing the inner tube 2 from scalding the user, and on the other hand, preventing fire.

[0036] To be more specific, the heating element includes a substrate 8 and a heating wire 9. The high-temperature resistant substrate 8 is circular and is coaxially fixed to the inner bottom wall of the inner tube 2 by bolt connection. An installation groove is provided on the upper plate surface of the substrate 8, and the heating wire 9 is embedded in the installation groove. The heating wire 9 is arranged in a spiral disk shape. The heating wire 9 is electrically connected to the regulating switch 10, and the regulating switch 10 is electrically connected to the external power supply. The heating degree of the heating wire 9 is controlled by the regulating switch 10.

[0037] When the heater is in use, the heating wire 9 is energized to generate heat, and the heat is dissipated outwards through the heat dissipation hole 1 3 and the heat dissipation hole 2 4. The outer mesh cover 5 can prevent people or objects from contacting or approaching the inner tube 2 to prevent burns or fire. Since the heat dissipation hole 1 3 is provided at the upper end of the inner tube 2, the heater can dissipate heat above and around the outer mesh cover 5 to improve the heating efficiency.

Except for the shapes of the groove 7 and the heat dissipation hole 3, the other structures of this embodiment are the same as those of the embodiment 1. The center line of the groove 7 in this embodiment is a straight line and is perpendicular to the axis of the inner cylinder 2. Multiple grooves 7 are radially arranged with the axis of the inner cylinder 2 as the center; the closer to the outer wall of the inner cylinder 2, the longer the length of the groove 7.

[0040] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0041] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
