Problems solved by technology

However, when in use, the rotary valve must be closely attached to the upper button seat to achieve the effect of closing the air, so that there is a large friction force between the rotary valve and the upper button seat, so that when the rotary valve rotates, it is located on the upper button seat. The ribs on the inner side wall of the boiler have a tendency to break away from the opening groove under the action of greater friction. Over time, the ribs are easily damaged, resulting in unstable connection between the upper button seat and the lower button seat, thus affecting the normal operation of the exhaust pot button

Embodiment 1

[0045] Such as figure 1 with figure 2 As shown, the exhaust cover 1 is composed of an exhaust cover 1, a positioning seat 2, an upper exhaust seat 3 and a lower exhaust seat 4 from top to bottom. Wherein, the lower exhaust seat 4, the upper exhaust seat 3 and the positioning seat 2 are connected together by a screw 5.

[0046] Specifically, the lower exhaust seat 4 is in the shape of a truncated cone, and the outer edge of the lower exhaust seat 4 is provided with a number of air inlets 4a, and several air inlets 4a are evenly distributed along the circumference so as to improve the appearance of the lower exhaust seat 4. sex.

[0047] The upper exhaust seat 3 is arranged above the lower exhaust seat 4 and the position is opposite to the lower exhaust seat 4 . In this example, if figure 2 , Image 6 with Figure 7 As shown, the upper exhaust seat 3 is cylindrical, and a clamping opening 6 for clamping the pot cover 7 is formed between the lower end of the upper exhaust...

Embodiment 2

[0059] The structure and principle of this second embodiment are basically the same as that of the first embodiment, except that there is an annular groove on the inner wall of the connecting part 1b, the positioning seat 2 is disc-shaped and made of elastic material, and the outer surface of the positioning seat 2 The thickness along the outer edge of the positioning seat 2 in the annular groove matches the groove width of the annular groove.

Abstract

The invention provides an exhaust head cover and belongs to the technical field of kitchen supplies. The problem that an existing exhaust pot button is not stable in working is solved. The exhaust head cover comprises an exhaust cover, a positioning base, an upper exhaust base and a lower exhaust base which are sequentially arranged from top to bottom, wherein the positioning base, the upper exhaust base and the lower exhaust base are connected through bolts, a clamping mouth is formed between the upper exhaust base and the lower exhaust base, an air outlet is formed in the upper exhaust base, the exhaust cover and the positioning base are axially connected, the exhaust cover comprises a holding part and a connecting part which is connected with the positioning base, the connecting part is cylinder-shaped, an exhaust mouth communicated with the air outlet is formed in the side wall of the connecting part, the air outlet is located inside the connecting part, and a gap is formed between the inner side wall of the connecting part and the outer wall of the upper exhaust base. The exhaust head cover has the advantages of being stable in working and long in service life.

Description

technical field [0001] The invention belongs to the technical field of kitchen supplies and relates to an exhaust cap. Background technique [0002] Ordinary pots on the market are usually provided with or without vents on the pot cover. When there is a vent hole in the pot cover, it takes a long time to cook food, which is time-consuming and energy-consuming; when there is no vent hole in the pot cover, a sealed space is formed between the pot cover and the pot body, which reduces heat loss and cooks food The cooking time is short, but when the food in the pot boils, it is easy to make the soup spill out of the pot and dirty the stove or cause the fire source to go out, which is inconvenient to use. [0003] For this situation, people have realized this deficiency and made improvements, such as a kind of exhaust pot button [application number: 200720112321.6; authorization announcement number: CN 201064398Y] proposed by the Chinese patent literature, including the lower bu...
