电热烟壶用壶盖

Abstract

本方案提供一种电热烟壶用壶盖，包括中空盖体、带间距的安装在中空盖体内的数个导热元件，所述的中空盖体的外表面上开有与外界连通供新鲜空气进入的入气孔，中空盖体的下底面中心上开有通向烟杯的通气孔，导热元件上开有空气导向孔，相邻两导热元件上的空气导向孔呈远离排布，通过间距安装的导热元件经空气导向孔在中空盖体内形成连通且带有扭折的空气通道，空气通道的两端分别对应为入气孔和通气孔。本实用新型通过在壶体上设壶盖对进入的新鲜空气进行逐级预热后进入烟杯，而壶盖的预热热量由壶体内烟仓腔或 / 和烟杯热交换，或 / 和上升热气与导热元件热交换传导而来。扭折能避免水凝珠产生时堵塞出入口，更能延长空气通道长度。

Claims

1. A lid for an electrically heated pipe, the electrically heated pipe comprising a pipe body (1) having an upper opening pipe cavity (11) in the upper part of the pipe body (1), a pipe cup (3) heated by a heating element being arranged in the pipe cavity (11), characterized in that: A lid (2) is detachably connected to the top of the tobacco chamber (11) to seal the opening of the tobacco chamber. The lid (2) includes a hollow lid body (21) and several heat-conducting elements (22) installed in the hollow lid body (21) with spacing. An air inlet (211) is opened on the outer surface of the hollow lid body (21) to allow fresh air to enter. A vent (212) leading to the tobacco cup (3) is opened on the center of the bottom surface of the hollow lid body (21). An air guide is opened on the heat-conducting elements (22). The air guide holes (221) on two adjacent heat-conducting elements (22) are arranged far apart. The heat-conducting elements installed at intervals form a connected and twisted air channel in the hollow cover (21) through the air guide holes (221). The two ends of the air channel correspond to the air inlet (211) and the vent (212) respectively. The heat in the smoke chamber (11) and / or the smoke cup (3) is conducted to the heat-conducting elements (22) through the vent (212) and / or the bottom surface of the hollow cover (21). Fresh air enters the air passage of the hollow cover (21), is preheated, and then enters the tobacco cup, where it mixes with the tobacco in the tobacco cup to form smoke for direct or indirect inhalation.

2. The electrically heated chafing dish lid of claim 1, wherein: The aforementioned heat-conducting elements (22) are arranged in concentrically spaced, progressively cylindrical grid rings within the hollow cover body. The upper top wall and lower bottom surface of the hollow cover body (21) are respectively closed and connected to the progressively cylindrical grid rings, thereby dividing the central cover body into concentric progressively ring-layer spaces through the progressively cylindrical grid rings. The adjacent two-level ring-layer spaces are connected through air guide holes (221). The air inlet (211) is located on the peripheral side wall of the central cover body. The diameter of the smallest diameter cylindrical grid ring is greater than or equal to the outer diameter of the vent hole (212).

3. The electrically heated chafing dish lid of claim 2, wherein: The hollow cover (21) is connected to a heat-conducting component that contacts the smoke chamber (11) and / or the smoke cup (3) on its bottom surface, and a ventilation hole (212) is formed by the central through hole of the heat-conducting component. The heat-conducting component transmits heat through the bottom surface of the hollow cover (21) to the progressive cylindrical grid ring, thereby preheating the fresh air in the air channel.

4. The electric hot kettle lid according to claim 1 or 2 or 3, characterized in that: Air guide holes (221) are staggered in stages on the heat-conducting element inside the hollow cover.

5. The electric hot chalice cover according to claim 1 or 2 or 3, characterized in that: The top surface of the hollow cover (21) above the vent (212) is the closed surface (213).

6. The electrically heated chafing dish lid of claim 4 wherein: The top surface of the hollow cover (21) above the vent (212) is the closed surface (213).

7. The electric hot chalice cover according to claim 1 or 2 or 3, characterized in that: The hollow cover (21) is surrounded by a heat insulation sleeve (5) with an unsealed air inlet (211).

8. The electrically heated chafing dish lid of claim 4, wherein: The hollow cover (21) is surrounded by a heat insulation sleeve (5) with an unsealed air inlet (211).

9. The electrically heated chalice lid of claim 5, wherein: The hollow cover (21) is surrounded by a heat insulation sleeve (5) with an unsealed air inlet (211).

10. The electrically heated chafing dish lid of claim 6, wherein: The hollow cover (21) is surrounded by a heat insulation sleeve (5) with an unsealed air inlet (211).
