Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of gas stove accessories, and specifically relates to a gas stove knob mechanism. BACKGROUND

[0002] The internal structure of the gas stove switch knob is composed of multiple key components, including contacts, springs, knob shafts, and covers.

[0003] Firstly, the contact is one of the most important components inside the gas stove switch knob. The contact is connected to the external operating lever and is mainly responsible for the on-off control of the switch. The contact is usually made of metal material because metal has good conductivity. When the operating lever rotates the knob, the contact will make contact with or break away from the wire, thereby controlling the on-off state of the gas stove.

[0004] Secondly, the spring is an important component inside the gas stove switch knob that restores the position of the knob. The spring is usually located around the knob shaft and restores the knob to the original position through elastic force. This is very important after operation is completed because it ensures that the knob can automatically rebound and the gas stove can be normally closed.

[0005] The knob shaft is another key component of the gas stove switch knob, which is a connector between the contact and the spring. The knob shaft is an elongated metal rod, one end of which is connected to the contact and the other end of which is connected to the spring. When the knob is rotated, the knob shaft will drive the contact to make contact with or break away from the wire, and at the same time, the spring will be restored.

[0006] In addition, the cover is an important component for protecting the internal structure of the gas stove switch knob. The cover is usually made of strong plastic or metal material to ensure that the switch knob is not disturbed by external forces. The design of the cover can also prevent the contact from being contaminated by dust, oil stains, or other debris, thereby ensuring the normal operation of the gas stove.

[0007] The gap between the inner end of the knob shaft of the existing gas stove knob switch and the shaft seat has poor sealing performance, and water or oil stains can easily penetrate during cooking, causing internal rust or oil stain accumulation, which can cause the knob to rotate and be stuck, and the switch to be hindered. SUMMARY

[0008] In order to make up for the deficiencies in the prior art, the utility model provides a gas stove knob mechanism, which has good sealing performance and can avoid water or oil stains from penetrating, thereby ensuring the smoothness of the knob rotation.

[0009] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0010] A gas stove knob mechanism, comprising a knob, a knob base and a rubber cap, an outer wall of an end of a rotation shaft of the knob is provided with an annular groove, the knob is rotationally connected in the knob base, the rubber cap is provided with a through hole, the rubber cap is sleeved on an end of the knob base and the through hole is in interference fit with the annular groove.

[0011] Further, the knob base comprises a knob mounting groove and a shaft sleeve coaxially connected, and the rotation shaft of the knob is arranged in the shaft sleeve.

[0012] Further, the outer wall of the knob mounting groove is provided with two groups of connecting ears, and the connecting ears are provided with connecting holes.

[0013] Further, the two groups of connecting ears are arranged in two layers and staggered up and down.

[0014] Further, the top surface of the connecting ear in the upper layer is flush with the top surface of the knob mounting groove, and the bottom surface of the connecting ear in the lower layer is flush with the bottom surface of the knob mounting groove.

[0015] Further, the groove wall of the knob mounting groove is provided with a plurality of positioning sockets.

[0016] Compared with the prior art, the gas stove knob mechanism has the following beneficial technical effects:

[0017] The gas stove knob mechanism of the utility model, the rubber cap is sleeved on the end of the knob base and the through hole is in interference fit with the annular groove, can effectively seal the gap between the knob rotation shaft and the knob base, avoid water or oil stains from seeping into the knob base, thereby preventing the inside of the knob base from rusting or accumulating oil stains, and ensuring the smoothness of the knob rotation. BRIEF DESCRIPTION OF DRAWINGS
