Abstract
The utility model discloses a waterproof structure of a turn knob switch of a gas cooker, which comprises a valve rod passing through a gas cooker panel, a turn knob arranged on the upper part of the valve rod, and a valve base arranged on the periphery of the lower part of the valve rod. The waterproof structure is characterized in that a protection sleeve and a sealing cover are also arranged between the valve rod and the gas cooker panel to form a sealed structure. The utility model can effectively prevent dirt and water drips from entering the turn knob switch from the gap between the valve rod and the gas cooker panel to guarantee the reliable work of the switch assembly of the gas cooker.
Description
Technical field
The utility model relates to the technical field of gas-cooker, especially refers to the rotary switch in the gas-cooker is partly improved, and the waterproof construction of a kind of gas-cooker upper knob switch of making.
Background technology
Present employed gas-cooker, its switch module partly comprises at the knob on the gas-cooker panel, runs through the valve rod of panel setting, in order to valve seat that valve rod is set, be arranged on spring and microswitch and conducting strip etc. between valve rod and the valve seat, when the user puts cooking stove burning, press and rotate knob, this moment spring compression, knob drives valve rod and moves down and rotate, and realizes igniting then.
Wherein, knob is arranged on the valve rod top, and knob needs the panel of relative gas-cooker up and down, therefore, it between knob and the panel open structure, also be to have bigger slit between knob and the panel, and valve rod need run through the gas-cooker panel, certainly exist the slit between valve rod and the panel like this.As everyone knows, residing working environment greasy dirt of gas-cooker and water droplet are more, like this, dust, greasy dirt and water droplet are very easy to enter valve seat inside from the slit between valve rod and the panel, then can pollute, corrode switch block, influence the reliability of gas combustion range ignition, also can stop up the activity space between valve rod and the valve seat simultaneously, influence the active operation of parts, cause the damage of gas-cooker.Therefore, be necessary the rotary switch on the existing gas-cooker is improved.
Summary of the invention
Technical problem to be solved in the utility model is the present situation at prior art, a kind of waterproof construction of gas-cooker upper knob switch is provided, it can prevent effectively that dirt, water droplet from entering the inside of rotary switch from the space between valve rod and the gas-cooker panel, guarantee the reliably working of gas stove switch assembly then.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the waterproof construction of this gas-cooker upper knob switch, comprise the valve rod that runs through the setting of gas-cooker panel, be arranged on knob on the valve rod top, be arranged on the valve seat of stem lower portion periphery, it is characterized in that: also include protective sleeve and capping;
Wherein, described protective sleeve is shape for hat and the top has through hole, and this hole size and described valve rod external diameter adapt and pass for valve rod, and this protective sleeve just is set in outside the described valve rod and described relatively valve seat is fixed;
Described capping cross section is the T type and covers on the described protective sleeve; the lateral part of this T type capping also has medium pore and passes for described valve rod; the vertical part of this T type capping is movably connected in the periphery, top of described protective sleeve, and bottom, the edge, lateral part of this T type capping is just in time pressed close to mutually with the surface of described gas-cooker panel.
The vertical part of above-mentioned T type capping can adopt with the movable connection method of periphery, described protective sleeve top and be threaded; protective sleeve is up and down relatively in capping like this; when actual installation; rotary closure slowly; just in time paste mutually with the surface of gas-cooker panel bottom, edge, lateral part until capping; at this moment, capping just forms good sealing with panel surface, and is simple in structure and very practical.
Be enhanced leaktightness, can also be lined with sealing gasket between the bottom, edge of the lateral part of described T type capping and the surface of described gas-cooker panel.
The fixing mode of the described relatively valve seat of described protective sleeve can realize in the following way: the edge part of this shape for hat protective sleeve is fixed on the described valve seat by screw.
For preventing that further dirt and water droplet from entering within the valve seat; strengthen the parts of protection stem lower portion; can also have additional bonnet between described protective sleeve and the valve seat; the cross section of this bonnet is inverted T shape; central authorities have the through hole that adapts with described valve rod and pass for valve rod; this bonnet is set in described valve rod periphery, and the lateral part of bonnet is fixed on the described valve seat top.
For the vertical part of reinforcement bonnet and the sealing property between the valve rod, can be provided with first sealing ring between the vertical part inboard of described bonnet and the valve rod.
For strengthening the sealing property of bonnet and valve base surface, can be provided with second sealing ring between the bottom, lateral part of described bonnet and the valve seat.
Compared with prior art, the utility model is by the setting of protective sleeve and capping between valve rod and the gas-cooker panel, on the space between valve rod and the gas-cooker panel, form a seal protection structure, dirt and water droplet are subjected to the obstruct of panel surface upper cover, and can't enter the inside of rotary switch from the space between valve rod and the gas-cooker panel, guarantee the reliably working of gas stove switch assembly, reached the technique effect of water proof and dust proof; The waterproof construction of this rotary switch does not change the structure that has gas-cooker now, and only increasing by two parts can deal with problems, and is highly susceptible to implementing.
