Description
Technical field
The utility model relates to the household kitchen electric appliance technical field, especially relates to the exhaust structure of pressing of a kind of pressure cooker or pressure cooker pot cover.
Background technology
At present, pressure cooker on the market or pressure cooker, generally be to come controlled pressure by pressure limiting valve, when food in the pot cook finish after, manually the bonnet with pressure limiting valve takes off, and makes that gas is discharged in the pot, but since the temperature in this moment pot than higher, the user is when taking off bonnet, and the high-temperature steam that is ejected is easily scalded.
Scalded by high-temperature steam for fear of the user, the exhaust apparatus that has is designed to the structure of similar lever, end by presses lever, thereby make the lever other end lever up pressure limiting valve and realize exhaust, as Chinese patent Granted publication number: CN 201710170U, January 19 2011 Granted publication day, a kind of push type exhaust structure is disclosed, comprise rotary handle, exhaust button is housed on the rotary handle, be equipped with by the fixing spacing return spring of foundary weight the exhaust button bottom, transmission levers one end is fixed in the exhaust button bottom, the other end is butted on a side bottom of pressure limiting valve body, and the pressure limiting valve body is loaded on by the fixing blast pipe top of holder, and the pressure limiting thimble of pressure limiting valve inner peaks at the opening part of blast pipe.Though can avoid the danger of being scalded by steam like this, when exhaust, need keep pressed state for a long time, in a single day hand leaves exhaust button, and pressure limiting valve namely stops exhaust, and evacuation time is longer usually, therefore uses very inconvenient.
The utility model content
The utility model is to press exhaust structure in the prior art and need keep for a long time pressing the deficiency that could continue exhaust in order to overcome, and a kind of comparatively easy exhaust structure of pressing that need not to keep for a long time pressing, operating is provided.
To achieve these goals, the utility model is by the following technical solutions:
A kind of pot cover of the present utility model press exhaust structure, comprise the exhaust pedestal that is arranged on the pot cover, the guide holder that runs through the exhaust pedestal and the connecting rod that can in guide holder, slide, the transmission gear piece is fixedly arranged at described connecting rod top, described exhaust pedestal is provided with lid, lid is provided with centre bore, be provided with in the centre bore edge can with the suitable chute of transmission gear piece and inclined-plane, location, the top of described transmission gear piece is provided with the button that offsets with the transmission gear piece, is provided with helical spring between described transmission gear piece and the guide holder.Under original state, by pressing button, the transmission gear piece promotes connecting rod and moves downward, and is connected with ambient atmosphere in the pot.After release button, the transmission gear piece moves upward under helical spring effect, and be positioned in simultaneously on the inclined-plane, location at exhaust pedestal centre bore edge, to vacate a gap between connecting rod and the exhaust pedestal, steam can be discharged to the external world in pot, until internal and external pressure balance.Can press button again afterwards, the transmission gear piece is upspring by helical spring, enters in the chute afterwards and button is returned to original state together, and connecting rod and exhaust pedestal are got back to sealing state.
As preferably, described connecting rod lower end is provided with flange, and described guide holder lower end is provided with diameter greater than the counterbore of flange.Under original state, flange and counterbore are in sealing state, and when connecting rod descended, flange separated with counterbore, and the gas in the pot can be discharged.
As preferably, the sidewall of described guide holder is provided with through hole, is provided with the steam vent of level in the described exhaust pedestal, and described steam vent is connected with through hole.Steam vent is the level of state, and gas can be discharged from the side of exhaust pedestal like this, avoids user's hand to be scalded by high-temperature steam.
As preferably, described flange is provided with the sealing ring that can contact with the counterbore bottom surface, is provided with sealing ring between described connecting rod and the guide holder.Sealing ring can prevent that internal gas from flowing out, and sealing ring can prevent when the user presses button that gas from scurrying to button positions, and the user is played the better protect effect.
As preferably, the edge of described exhaust pedestal is provided with buckle, the madial wall of described lid be provided with can with the projection of buckle clamping.Lid is connected with the exhaust pedestal by buckle, and it is comparatively convenient to install, and lid can play dustproof effect preferably to inside.
Therefore, the utlity model has following beneficial effect: press once and can keep exhaust condition, need not to remain on just exhaust smoothly of pressed state always, comparatively convenient and safety are used in operation.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation figure of the utility model open mode.
Among the figure, lid 1, button 2, transmission gear piece 3, helical spring 4, sealing ring 5, connecting rod 6, flange 6a, sealing ring 7, guide holder 8, through hole 8a, pot cover 9, exhaust pedestal 10, steam vent 10a, nut 11.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Among the embodiment as shown in Figure 1, a kind of pot cover press exhaust structure, comprise exhaust pedestal 10, guide holder 8, connecting rod 6 and transmission gear piece 3, wherein the exhaust pedestal is arranged on the pot cover 9, guide holder runs through the exhaust pedestal, and is fixed on the exhaust pedestal by external screw thread and nut 11, establishes the hole in the middle of the guide holder, connecting rod can slide in the hole, and the transmission gear piece is by being bolted to the connecting rod top.Also has lid 1 at the exhaust pedestal, lid is provided with centre bore, be provided with in the centre bore edge can with the suitable chute of transmission gear piece and inclined-plane, location, be provided with buckle at the edge of exhaust pedestal, the madial wall of lid is provided with projection, utilizes buckle and projection to cooperate lid is positioned.The top of transmission gear piece is provided with button 2, and button and transmission gear piece offset, and are provided with helical spring 4 between transmission gear piece and guide holder.The sidewall of guide holder is provided with through hole 8a, is provided with the steam vent 10a of level in the exhaust pedestal, and steam vent is connected with through hole.The connecting rod lower end is provided with flange 6a, and the guide holder lower end is provided with diameter greater than the counterbore of flange.Flange is provided with the sealing ring 7 that can contact with the counterbore bottom surface, is provided with sealing ring 5 between connecting rod and the guide holder.
When being positioned at original state, as shown in Figure 1, fit in the sealing ring on the flange and counterbore bottom surface, and with extraneous gas can not circulate in the pot this moment, is in sealing state.When needs lose heart, the finger presses button, transmission gear piece and connecting rod descend, helical spring is compressed, after finger unclamped, the helical spring bounce-back was upwards propped up transmission gear piece and connecting rod, this moment, the transmission gear piece was positioned on the inclined-plane, location of lid, thereby made the gap that produces 1.5mm between the flange of the counterbore of guide holder and connecting rod carry out exhaust.Gas in the pot flow in the through hole of guide holder sidewall through the gap between counterbore and the flange, and flow in the steam vent that is communicated with it, discharges from exhaust pedestal side.Press the button again after finishing exhaust, side transmission gear piece and connecting rod just are returned to initial position.
