Description

内置电热丝的空气加热装置 技术领域
本发明涉及内置电热丝的空气加热装置。
背景技术
电热丝广泛应用于加热装置，如空气加热装置，但现有空气加热装置结构复杂，使用不方便。
发明内容
本发明的目的在于提供一种内置电热丝的空气加热装置，其能加热空气，且使用方便。
为实现上述目的，本发明的技术方案是设计一种内置电热丝的空气加热装置，包括竖置圆筒状加热筒，加热筒上下两端开口；
所述加热筒的筒壁内置有螺旋状电热丝，螺旋状电热丝与加热筒共轴心；
所述加热筒内部设有若干导热网板，各导热网板与加热筒共轴心，且各导热网板沿加热筒轴向均布；各导热网板与加热筒内壁紧配合；
各导热网板上分别均布有若干通孔；
竖向相邻的两个导热网板，它们的通孔相互错位。
优选的，所述加热筒外壁覆盖有隔热层。
本发明的优点和有益效果在于：提供一种内置电热丝的空气加热装置，其能加热空气，且使用方便。
电热丝可以加热加热筒，进而加热导热网板，加热筒内的空气被加热后由加热筒顶端输出，加热筒内气压下降，加热筒底端附近的待加热空气会自动补充进入加热筒，从而形成热空气的持续输出。
竖向相邻两个导热网板的通孔相互错位，能让空气在加热筒内部上升的过程中产生湍流，提高加热效果。
附图说明
图1是本发明的示意图。
具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步描述。以下实施例仅用于更加清楚地说明本发明的技术方案，而不能以此来限制本发明的保护范围。
本发明具体实施的技术方案是：
如图1所示，一种内置电热丝的空气加热装置，包括竖置圆筒状加热筒1，加热筒1上下两端开口；
所述加热筒1的筒壁内置有螺旋状电热丝，螺旋状电热丝与加热筒1共轴心；
所述加热筒1内部设有若干导热网板2，各导热网板2与加热筒1共轴心，且各导热网板2沿加热筒1轴向均布；各导热网板2与加热筒1内壁紧配合；
各导热网板2上分别均布有若干通孔；
竖向相邻的两个导热网板2，它们的通孔相互错位。
优选的，所述加热筒1外壁覆盖有隔热层。
电热丝可以加热加热筒1，进而加热导热网板2，加热筒1内的空气被加热后由加热筒1顶端输出，加热筒1内气压下降，加热筒1底端附近的待加热空气会自动补充进入加热筒1，从而形成热空气的持续输出。
竖向相邻两个导热网板2的通孔相互错位，能让空气在加热筒1内部上升的过程中产生湍流，提高加热效果。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
