Problems solved by technology

[0002] At present, there is a one-piece knob that includes a holding part and a connecting part. Due to the need for high temperature resistance, such as a metal knob for a gas stove, it is made of a zinc alloy or aluminum alloy by die-casting. Due to die-casting The product has a water inlet that injects molten metal into the mold. After the product is formed, the position of the water inlet will form a redundant spike on the knob. The length of the spike is generally greater than 1mm. In order to be able to To use the knob normally, the spike must be removed through a process, such as lathe turning or manual grinding, which will inevitably increase the cost, and if the metal knob is heated by the heat conducted by the cooker, since metal is a good conductor of heat, The surface temperature of the metal knob will be very high, and the user's hands cannot directly touch the metal knob
There is also a plastic knob that is also used in stoves, but the plastic will age or even melt under high temperature for a long time, and will soon fail

Embodiment 1

[0023] Such as figure 1 , figure 2 , image 3 , Figure 4 , the knob includes a handle part (1), a connecting part (2) and a decorative part (3). The central part of the knob is the connecting part (2), and the connecting part (2) includes a "D"-shaped hole and a cantilever "\"-shaped protrusion (21) for interference fit, and the connecting part (2) It includes a protrusion (22) for preventing the protrusion (21) from being plastically deformed, and the holding part (1) and the connecting part (2) are connected through a reinforcing rib (23). The connecting part (2) of the knob of the present invention has a protrusion (21) which can be matched with an external connecting piece, and the protrusion (21) is more likely to produce elastic deformation under pressure than a smooth surface. Therefore, the external connecting piece with large tolerances in matching dimensions can be more easily assembled to the connecting portion (2) of the knob of the present invention through ...

Embodiment 2

[0025] Such as Figure 5 , the knob includes a gripping part (1) and a connecting part (2). The connecting part (2) is a shaft connected with the outside. The shaft has features to prevent it from coming out, such as grooves or radial holes or dimples.

Embodiment 3

[0027] Such as Image 6 , the present invention also proposes a cooker (1), which includes the knob (2) as described in Embodiment 1 above. The cooker may be a gas cooker, an electromagnetic cooker, an alcohol fuel cooker or other types of cooker.

Abstract

The invention provides a manufacturing method of a rotary knob. The manufacturing method of the rotary knob is characterized by comprising a glass melting process during which glass batch is heated into molten glass, and a shaping process during which the molten glass is placed inside a mold and manufactured into the required rotary knob. The shaped rotary knob manufactured through the method canavoid water inlet burs existing in rotary knobs shaped through die casting, so that the manufacturing method of the rotary knob can save a bur removing process and further save cost; glass materials can resist high temperature as high as 600 DEG C and accordingly can avoid heated melting in common stoves.
