Description

Technical Field

[0001] The invention belongs to the technical field of kitchenware and relates to a scalding-free pot cover with better sealing performance. Background Art

[0002] As one of the indispensable items in our kitchen, pot lid plays an important role in frying and stewing. However, the existing pot lid often does not handle the large amount of water vapor generated during stewing well, so that people are often scalded by the water vapor emitted instantly when opening the lid to check whether the food is cooked. Moreover, the water vapor quickly condenses into small water droplets when it cools down and falls into the pot, affecting the taste of the food. Summary of the invention

[0003] The purpose of the present invention is to solve the above problems in the prior art and to provide a scald-free pot cover with better sealing performance. The scald-free pot cover with better sealing performance is easy to use, labor-saving and safer.

[0004] The objective of the present invention can be achieved through the following technical solutions: a scald-free pot cover with better sealing performance, comprising a cover plate with an opening at the upper end, an air storage cavity defined in the cover plate, two sealing mechanisms provided at the lower end of the cover plate, the two sealing mechanisms are symmetrically distributed about the center line of the cover plate, a first exhaust mechanism for adjusting the air pressure value inside and outside the pot is provided at the upper opening of the cover plate, a second exhaust mechanism is also provided at the upper end of the first exhaust mechanism, a handle mechanism for driving the exhaust mechanism to work is provided at the left end of the first exhaust mechanism, and six one-way exhaust valves are also provided on the lower end wall of the cover plate, the six one-way exhaust valves are grouped in three, and the two groups of one-way exhaust valves are symmetrically distributed about the center line of the cover plate.

[0005] When using the pot cover, water vapor generated by cooking enters the air storage chamber along the one-way exhaust valve, a part of the water vapor entering the air storage chamber flows to the sealing mechanism to increase the sealing effect between the edge of the pot cover and the pot, and the other part is discharged to the outside space along the first exhaust mechanism. If it is necessary to open the pot cover to detect whether the dish is cooked, the second exhaust mechanism can be triggered by the handle mechanism to quickly discharge the steam in the pot, while the sealing effect of the sealing mechanism is weakened, so that it is convenient to remove the pot cover from the pot, to avoid excessive steam in the pot blowing towards the face when opening the lid and causing burns. At the same time, the water vapor quickly condenses into small water droplets when it encounters cooling at the moment of opening the pot, and the water droplets flow into the sealing mechanism along the lower inner wall of the cover plate for unified collection, so as to avoid flowing back into the pot again and affecting the taste of the dish.

[0006] The above-mentioned scald-free pot cover with better sealing performance, the sealing mechanism includes a rubber shell detachably arranged at the lower end of the cover plate, and an air bag connected to the air storage chamber is installed in the rubber shell, and the air bag can collect small water droplets formed by the atomization of water vapor during cooking. A part of the water vapor entering the air storage chamber is discharged to the first exhaust mechanism and the second exhaust mechanism, and the other part of the water vapor enters the air bag, so that the volume of the air bag expands and squeezes the rubber shell. The rubber shell continuously fits to the edge of the pot under the action of external force, thereby increasing the sealing effect of the rubber shell on the pot. At the same time, at the moment of opening the pot cover, the water vapor is cooled and quickly condensed into small water droplets. Under the action of the gravity of the water droplets themselves, they flow along the lower inner wall of the cover plate to the air bag for unified collection, so as to prevent the small water droplets from flowing back into the pot and affecting the taste of the dishes. After cooking, the rubber shell can be removed from the lower end of the cover plate, and the distilled water in the air bag can be poured out to ensure normal use next time.

[0007] The above-mentioned scald-free pot cover with better sealing performance, the first exhaust mechanism includes an air vent set at the upper opening of the cover plate, the inner walls on the left and right sides of the air vent are respectively fixed with support rods, the two support rods are symmetrically distributed about the center line of the air vent, each of the support rods is provided with a filter for exhaust, an optical axis is rotatably connected between the two support rods, and a ventilation duct is provided in the optical axis for discharging the water vapor in the air storage cavity to the outside space. The water vapor generated when cooking flows to the air vent, and is discharged to the outside space through the ventilation duct in the optical axis, so as to adjust the pressure difference between the inside and outside of the pot, and avoid excessive pressure in the pot, so that the pot cover bounces off the pot.

[0008] The above-mentioned scald-free pot cover with better sealing performance, the handle mechanism includes a slide groove fixedly arranged on the left end face of the vent hole, and the upper and lower inner walls of the slide groove are respectively provided with limit grooves, and the two limit grooves are symmetrically distributed about the center line of the slide groove, and the handle is slidably connected in the slide groove, and the right end face of the handle is fixedly connected with an H-shaped bracket, and the upper and lower recesses of the H-shaped bracket are respectively slidably connected with spherical blocks matching the limit grooves, each of the spherical blocks is fixedly connected to the H-shaped bracket, and two tension springs are fixedly connected between the right end face of the H-shaped bracket and the right inner wall of the slide groove, and the two tension springs are symmetrically distributed about the center line of the slide groove, and a winding wheel is also sleeved on the optical axis of the exhaust mechanism, and a wire rope is also transmission-connected between the winding wheel and the right end face of the H-shaped bracket, and one end of the wire rope is fixedly connected to the right end face of the H-shaped bracket, and the other end is fixedly connected to the winding wheel.

[0009] Initially, the two spherical blocks are located in the limit grooves of the upper and lower inner walls of the slide groove under the action of two compression springs to limit the handle. Before checking whether the dish is cooked, pull the handle in the slide groove to slide outside the slide groove. Under the action of external force, the two spherical blocks slide out of the two limit grooves respectively, so that the spherical blocks contact the upper and lower inner walls of the slide groove, compress the compression springs to accumulate force, and while the handle is pulled in the slide groove to slide outside the slide groove, the H-shaped bracket stretches the two tension springs to accumulate force, and the H-shaped bracket pulls the rope, so that the rope drives the winding wheel to rotate relatively on the optical axis, providing power for the subsequent work of the second exhaust mechanism.

[0010] The above-mentioned scald-free pot cover with better sealing performance, the second exhaust mechanism includes a sleeve mounted on the optical axis, the sleeve is located below the support rod relative to the optical axis, five fan blades are fixedly connected to the sleeve, the five fan blades are evenly distributed on the outer peripheral side of the sleeve along the circumferential direction of the sleeve, the optical axis is also sleeved with a first bevel gear, the first bevel gear is located above the support rod relative to the optical axis, the left and right inner walls of the vent are respectively fixed with positioning rods, the two positioning rods are symmetrically distributed about the center line of the vent, each of the positioning rods is rotatably connected with a rotating shaft, each of the rotating shafts is sleeved with a second bevel gear meshing with the first bevel gear, and the end of the rotating shaft away from the optical axis is also fixed with a sealing baffle for blocking water vapor.

[0011] When the handle mechanism drives the winding wheel to rotate on the optical axis, the winding wheel drives the fan blades to rotate in the vent through the optical axis. When the fan blades rotate, the flow speed of water vapor in the vent is increased, and the water vapor is quickly discharged. At the same time, the optical axis drives the first bevel gear to rotate relatively, and the first bevel gear is engaged with the two second bevel gears to drive the two second bevel gears to rotate. The two second bevel gears respectively drive the sealing baffles to be selected through the two rotating shafts, so that the sealing baffles that are initially horizontally placed to seal the upper end of the vent are changed to be vertically placed, thereby increasing the opening area of ​​the vent, thereby accelerating the rapid discharge of water vapor. As the amount of water vapor in the pot gradually decreases, the effect of the sealing mechanism is reduced, and the pot lid is opened again to avoid a large amount of water vapor directly rushing to the face and causing burns.

[0012] Compared with the prior art, the scald-free pot cover with better sealing performance has the following advantages:

[0013] 1. Due to the two sealing mechanisms, the sealing mechanism can increase the sealing effect between the pot lid and the edge of the pot under the action of water vapor. At the same time, the sealing mechanism can collect small water droplets condensed by water vapor when the pot lid is opened to prevent water droplets from falling into the pot and affecting the taste of the dish.

[0014] 2. Since the sealing baffle seals the vent hole at the beginning to ensure the pressure in the pot, when you need to open the lid, open the sealing baffle, which can also speed up the discharge of gas in the pot and prevent steam from directly rushing to the face and causing burns.

DETAILED DESCRIPTION

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] like Figure 1 As shown, a scald-free pot cover with better sealing performance includes a cover plate 10 with an opening at the upper end, an air storage cavity 11 is defined in the cover plate 10, two sealing mechanisms are provided at the lower end of the cover plate 10, and the two sealing mechanisms are symmetrically distributed about the center line of the cover plate 10, a first exhaust mechanism for adjusting the air pressure value inside and outside the pot is provided at the upper opening of the cover plate 10, a second exhaust mechanism is also provided at the upper end of the first exhaust mechanism, a handle mechanism for driving the exhaust mechanism to work is provided at the left end of the first exhaust mechanism, and six one-way exhaust valves 12 are also provided on the lower end wall of the cover plate 10, the six one-way exhaust valves 12 are grouped into three, and the two groups of one-way exhaust valves 12 are symmetrically distributed about the center line of the cover plate 10.

[0023] When using the pot cover, the water vapor generated by cooking enters the air storage chamber 11 along the one-way exhaust valve 12, and a part of the water vapor entering the air storage chamber 11 flows to the sealing mechanism to increase the sealing effect between the edge of the pot cover and the pot, and the other part is discharged to the outside space along the first exhaust mechanism. If it is necessary to open the pot cover to detect whether the dish is cooked, the second exhaust mechanism can be triggered by the handle mechanism to quickly discharge the steam in the pot, and at the same time, the sealing effect of the sealing mechanism is weakened, which makes it easier to remove the pot cover from the pot, avoiding excessive steam in the pot blowing towards the face when opening the lid and causing burns. At the same time, the water vapor quickly condenses into small water droplets when it encounters cooling at the moment of opening the pot, and the water droplets flow into the sealing mechanism along the lower inner wall of the cover plate 10 for unified collection to avoid flowing back into the pot again and affecting the taste of the dish.

[0024] like Figure 1 As shown, the sealing mechanism includes a rubber shell 14 detachably arranged at the lower end of the cover plate 10, and an air bag 13 connected to the air storage chamber 11 is installed in the rubber shell 14. The air bag 13 can collect small water droplets formed by the atomization of water vapor during cooking. A part of the water vapor entering the air storage chamber 11 is discharged to the first exhaust mechanism and the second exhaust mechanism, and the other part of the water vapor enters the air bag 13, so that the volume of the air bag 13 expands and squeezes the rubber shell 14. The rubber shell 14 is constantly attached to the edge of the pot under the action of external force, which increases the sealing effect of the rubber shell 14 on the pot. At the same time, when the pot cover is opened, the water vapor is quickly condensed into small water droplets when it is cooled. Under the action of the gravity of the water droplets themselves, they flow along the lower inner wall of the cover plate 10 to the air bag 13 for unified collection, so as to prevent the small water droplets from flowing back into the pot and affecting the taste of the dishes. After cooking, the rubber shell 14 can be removed from the lower end of the cover plate 10, and the distilled water in the air bag 13 can be poured out to ensure normal use next time.

[0025] like Figure 1 , Figure 2 As shown, the first exhaust mechanism includes an air vent 15 provided at the upper opening of the cover plate 10, and support rods 24 are respectively fixed to the inner walls on the left and right sides of the air vent 15, and the two support rods 24 are symmetrically distributed about the center line of the air vent 15, and a filter 25 for exhaust is provided in each support rod 24, and an optical axis 26 is rotatably connected between the two support rods 24, and a ventilation pipe 27 for discharging the water vapor in the air storage cavity 11 to the outside space is provided in the optical axis 26. The water vapor generated when cooking flows to the air vent 15, and is discharged to the outside space through the ventilation pipe 27 in the optical axis 26, so as to adjust the pressure difference between the inside and outside of the pot, and avoid excessive pressure in the pot, so that the pot cover bounces off the pot.

[0026] like Figure 1 , Figure 2 and Figure 5As shown, the handle mechanism includes a slide groove 16 fixedly arranged on the left end surface of the vent hole 15, and the upper and lower inner walls of the slide groove 16 are respectively provided with limit grooves 18, and the two limit grooves 18 are symmetrically distributed about the center line of the slide groove 16. A handle 17 is slidably connected in the slide groove 16, and an H-shaped bracket 21 is fixedly connected to the right end surface of the handle 17. The upper and lower ends of the H-shaped bracket 21 are respectively slidably connected to spherical blocks 19 that match the limit grooves 18, and each spherical block 19 is connected to the H-shaped bracket 21. A compression spring 20 is fixedly connected between the frame 21, and two tension springs 22 are fixedly connected between the right end face of the H-shaped bracket 21 and the right inner wall of the slide groove 16. The two tension springs 22 are symmetrically distributed about the center line of the slide groove 16. A winding wheel 30 is also sleeved on the optical axis 26 of the exhaust mechanism, and a rope 23 is also transmission-connected between the winding wheel 30 and the right end face of the H-shaped bracket 21. One end of the rope 23 is fixedly connected to the right end face of the H-shaped bracket 21, and the other end is fixedly connected to the winding wheel 30.

[0027] Initially, the two spherical blocks 19 are respectively located in the limiting grooves 18 of the upper and lower inner walls of the slide groove 16 under the action of the two compression springs 20, limiting the handle 17. Before checking whether the dish is cooked, the handle 17 is pulled in the slide groove 16 to slide toward the outside of the slide groove 16. Under the action of external force, the two spherical blocks 19 slide out of the two limiting grooves 18 respectively, so that the spherical blocks 19 contact the upper and lower inner walls of the slide groove 16, compress the compression springs 20 to store force, and while the handle 17 is pulled in the slide groove 16 to slide toward the outside of the slide groove 16, the H-shaped bracket 21 stretches the two tension springs 22 to store force, and the H-shaped bracket 21 pulls the rope 23, so that the rope 23 drives the winding wheel 30 to rotate relatively on the optical axis 26, providing power for the subsequent work of the second exhaust mechanism.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the second exhaust mechanism includes a sleeve 28 sleeved on the optical axis 26, and the sleeve 28 is located below the support rod 24 relative to the optical axis 26. Five fan blades 29 are fixedly connected to the sleeve 28, and the five fan blades 29 are evenly distributed on the outer peripheral side of the sleeve 28 along the circumferential direction of the sleeve 28. A first bevel gear 31 is also sleeved on the optical axis 26, and the first bevel gear 31 is located above the support rod 24 relative to the optical axis 26. Positioning rods 35 are respectively fixedly connected to the inner walls of the left and right sides of the vent 15, and the two positioning rods 35 are symmetrically distributed about the center line of the vent 15. A rotating shaft 33 is rotatably connected to each positioning rod 35, and each rotating shaft 33 is sleeved with a second bevel gear 32 meshing with the first bevel gear 31. The end of the rotating shaft 33 away from the optical axis 26 is also fixedly connected to a sealing baffle 34 for blocking water vapor.

[0029] When the handle mechanism drives the winding wheel 30 to rotate on the optical axis 26, the winding wheel 30 drives the fan blades 29 to rotate in the vent 15 through the optical axis 26. When the fan blades 29 rotate, the flow speed of the water vapor in the vent 15 is increased, and the rapid discharge of the water vapor is accelerated. At the same time, the optical axis 26 drives the first bevel gear 31 to rotate relatively, and the first bevel gear 31 is engaged with the two second bevel gears 32 to drive the two second bevel gears 32 to rotate. The two second bevel gears 32 drive the sealing baffles 34 to be selected through the two rotating shafts 33, so that the sealing baffles 34 that are initially horizontally placed to seal the upper end of the vent 15 are changed to be vertically placed, thereby increasing the opening area of ​​the vent 15, thereby accelerating the rapid discharge of water vapor. As the amount of water vapor in the pot gradually decreases, the effect of the sealing mechanism is reduced, and the pot lid is opened again to avoid a large amount of water vapor directly rushing to the face and causing burns.
