Description

Technical Field

[0001] The invention relates to the technical field of plateau water-boiling and rice-cooking appliances, in particular to a water-boiling and rice-cooking device with a self-pressurized gas or liquid control device. Background Art

[0002] In plateau areas, the higher the altitude, the lower the air pressure. At an altitude of 4,000 meters, the boiling point of water is about 88 degrees. The low temperature cannot really kill bacteria or cook food, and cannot meet the needs of life. Therefore, it is necessary to use a pressure cooker to boil water and cook food for consumption. However, some existing high-pressure water boilers need to open the lid to pour out the water after boiling the water, which is more troublesome. For this reason, we provide a water boiling and cooking device with a self-pressurized gas or liquid control device to solve the above problem. Summary of the invention

[0003] The object of the present invention is to overcome the disadvantages of the prior art and provide a water-boiling and rice-cooking device with a self-pressurized gas or liquid control device.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] A water-boiling and rice-cooking device with a self-pressurized gas or liquid control device comprises a container body, a cover body is detachably and hermetically connected to the opening of the container body, an automatic pressure-relieving and discharging device is connected to the upper surface of the cover body, the automatic pressure-relieving and discharging device comprises a connecting portion fixedly connected to the cover body, an outer shell is rotatably connected to the connecting portion, a discharge joint connected to the outer shell is arranged on the outer surface of the outer shell, a valve core capable of opening and closing the discharge joint by lifting is arranged inside the outer shell, a closing cover is installed at the opening of the outer shell, a liquid guide tube extending to the interior of the container body is detachably connected to the input end of the connecting portion, and a handle is also installed on the upper surface.

[0006] Preferably, the liquid guiding tube comprises a liquid guiding tube body, and at least one third sealing groove is formed on the outer surface of the connecting end of the liquid guiding tube body, and a third sealing ring is installed in each of the third sealing grooves.

[0007] Preferably, the valve core includes an upper core body arranged inside the outer shell, the bottom of the upper core body is fixedly connected to the lower core body, the top surface of the upper core body is fixedly connected to the driving rod, the driving rod extends to the outside through the closing cover, a first sealing groove is opened at the top of the outer surface of the upper core, a first sealing ring is sleeved in the first sealing groove and on the outer surface of the lower core, a spring is sleeved on the outer surface of the driving rod, and the spring is located between the closing cover and the upper core body.

[0008] Preferably, a discharge pipe is installed on the discharge joint, and the discharge pipe includes a connecting piece detachably installed with the discharge joint, a connecting chamber is opened inside the connecting piece, a discharge pipe body is rotatably connected inside the connecting chamber, and at least one second sealing groove is opened on the outer surface of the inlet end of the discharge pipe body, and a second sealing ring is arranged in each of the second sealing grooves.

[0009] Preferably, the discharge pipe body and the end of the connecting chamber are both in a trumpet shape.

[0010] Preferably, a hinge hole is formed at the end of the driving rod away from the upper core body, and a pry bar is hingedly connected to the end of the driving rod through the hinge hole.

[0011] Preferably, the distance from the center of the hinge hole to the end of the pry rod is a, and the distance from the center of the hinge hole to the top surface of the closing cover when the valve core is closed to the discharge joint is b, and a>b.

[0013] Preferably, the container body, the cover body, the automatic pressure relief discharge device and the liquid guiding tube are all made of stainless steel.

[0014] Preferably, the catheter is a telescopic tube that can be extended or contracted.

[0015] The present invention has the following advantages:

[0016] 1. The present invention controls the opening and closing of the discharge joint by lifting the valve core. When the air pressure in the container body reaches a certain value, the pressure causes the valve core to lift up, thereby releasing the seal of the discharge joint. The air pressure inside the container body is greater than the external air pressure, thereby causing a pressure difference between the inside and outside of the container. Since the liquid guide tube is connected to the connecting part, the liquid inside the container body is discharged through the channel formed by the connecting part, the outer shell and the discharge joint under the action of pressure, thereby achieving drainage without opening the lid. When the pressure is not enough to lift the valve core, the valve core can be manually lifted to discharge the water due to the residual pressure inside the container body. When the liquid guide tube is below the liquid level, due to the pressure difference between the inside and outside of the container body, the discharge joint discharges gas (high-pressure water vapor), thereby relieving the pressure inside the container body and preventing the container body from exploding due to excessive internal pressure.

[0017] 2. The present invention provides a third sealing ring on the third sealing groove, so that the liquid guiding tube body and the connecting part can be interference fit, thereby achieving connection without separation from the connecting part, and when it is not needed, the liquid guiding tube body only needs to be pulled out from the connecting part.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figure 1 —10 shows the embodiment:

[0032] A water-boiling and rice-cooking device with a self-pressurized gas or liquid control device comprises a container body 1, wherein a cover body 2 is detachably and hermetically connected to the opening of the container body 1, an automatic pressure-relieving and discharging device 3 is connected to the upper surface of the cover body 2, the automatic pressure-relieving and discharging device 3 comprises a connecting portion 32 fixedly connected to the cover body 2, an outer shell 31 is rotatably connected to the connecting portion 32, a discharging joint 34 communicating with the outer shell 31 is arranged on the outer surface of the outer shell 31, a valve core 35 capable of opening and closing the discharging joint 34 by lifting is arranged inside the outer shell 31, a closing cover 33 is installed at the opening of the outer shell 31, a liquid guide tube 4 extending to the interior of the container body 1 is detachably connected to the input end of the connecting portion 32, the liquid guide tube 4 is plugged into the connecting portion 32, and the connection is sealed, so that the liquid guide tube 4 can be disassembled and cleaned conveniently by plugging, and a handle 5 is also installed on the cover 2, so that the handle 5 is convenient for lifting the cover 2.

[0033] See also Figures 1 to 6As shown, the container can be used for both boiling water and cooking. When boiling water, the liquid guide tube 4 is inserted into the connecting portion 32, and the other end of the liquid guide tube 4 is submerged below the water level. When cooking, in order to prevent food from being blocked in the liquid guide tube 4, the liquid guide tube 4 is separated from the connecting portion and taken out from the container body 1 or the liquid guide tube 4 is placed above the liquid level. When boiling water, when the water inside the container body 1 boils and a certain pressure is reached inside, the pressure drives the valve core 35 to rise in the outer shell 31, thereby releasing the blockage of the discharge joint 34, so that the pressure inside the container body 1 can be released. Since the liquid guide tube 4 is connected to the connecting portion 32, the pressure causes the water to be discharged through the channel composed of the liquid guide tube 4, the connecting portion 32, the outer shell 31 and the discharge joint 34, so that the water is automatically discharged. When the pressure inside the container body 1 is not enough to lift the valve core 35, the valve core 35 can also be manually lifted. The valve core 35 is lifted up in the outer shell 31 to release the blockage of the discharge joint 34. Since there is still a pressure difference inside and outside the container body 1 that can discharge the water, the water can be discharged, and the function of draining can be realized without opening the lid. The above is the drainage process after the water is boiled. When it is necessary to cook rice, the liquid guide tube 4 needs to be separated from the connecting part 32 and taken out from the container body 1 or the liquid guide tube 4 is placed above the liquid level. After the rice inside the container body 1 is cooked, the pressure continues to increase, so that the valve core 35 is lifted up in the outer shell 31, and the blockage of the discharge joint 34 is released. Then, the high-pressure water vapor inside the container body 1 is discharged through the passage formed by the connecting part 32, the outer shell 31, and the discharge joint 34, thereby realizing the function of automatic pressure relief and preventing the internal pressure of the container body 1 from being too high and exploding. In this embodiment, since the outer shell 31 and the connecting part 32 are rotatably connected, the discharge direction of the discharge joint 34 can be controlled.

[0034] The liquid guiding tube 4 comprises a liquid guiding tube body 41 . The outer surface of the connecting end of the liquid guiding tube body 41 is provided with at least one third sealing groove 42 . A third sealing ring 43 is installed in each of the third sealing grooves 42 .

[0035] See also Figure 4 After the third sealing ring 43 is sleeved in the third sealing groove 42, the diameter of the outer surface of the third sealing ring 43 is greater than the diameter of the liquid guiding tube body 41. Since the third sealing ring 43 is made of rubber and has a certain elasticity, when the liquid guiding tube body 41 is inserted into the inner wall of the connecting portion 32, the third sealing ring 43 will be deformed and have an interference fit with the inner wall of the connecting portion 32, thereby preventing a gap between the inner wall of the connecting portion 32 and the liquid guiding tube body 41 and causing air leakage. In this embodiment, there are two third sealing grooves 42, and a third sealing ring 43 is arranged in each third sealing groove 42, so as to further improve the sealing between the liquid guiding tube body 41 and the connecting portion 32.

[0036] The valve core 35 includes an upper core body 351 arranged inside the outer shell 31, the bottom of the upper core body 351 is fixedly connected to the lower core body 352, the top surface of the upper core body 351 is fixedly connected to the driving rod 353, the driving rod 353 extends to the outside through the closing cover 33, and a first sealing groove 354 is opened at the top of the outer surface of the upper core body 351, and a first sealing ring 357 is sleeved in the first sealing groove 354 and on the outer surface of the lower core body 352, and a spring 355 is sleeved on the outer surface of the driving rod 353, and the spring 355 is located between the closing cover 33 and the upper core body 351.

[0037] See also Figure 6 and Figure 7 , by setting a first sealing ring 357 in the first sealing groove 354 and on the outer surface of the lower core 352, the diameter of the first sealing ring 357 is larger than the diameter of the upper core 351, so as to achieve interference fit with the outer shell 31. Since the first sealing ring 357 is made of rubber, it can undergo a certain deformation, so that the first sealing ring 357 is close to the inner wall of the outer shell 31 to achieve sealing, preventing water or gas from overflowing from the gap between the upper core 351 and the outer shell 31, and when the discharge joint 34 is released, water or gas overflows from the closing cover 33; the discharge joint 34 is closed under the elastic force of the spring 355 and the gravity of the upper core 351 and the lower core 352. When the pressure is greater than the elastic force and gravity mentioned above, the upper core 351 will move in the outer shell 31 to release the closure of the discharge joint 34, so that water or high-pressure gas will be discharged from the discharge joint 34.

[0038] A discharge pipe 36 is installed on the discharge joint 34, and the discharge pipe 36 includes a connecting piece 361 detachably installed with the discharge joint 34, a connecting chamber 362 is provided inside the connecting piece 361, a discharge pipe body 363 is rotatably connected inside the connecting chamber 362, and at least one second sealing groove 364 is provided on the outer surface of the inlet end of the discharge pipe body 363, and a second sealing ring 365 is provided in each of the second sealing grooves 364.

[0039] The ends of the discharge pipe body 363 and the connecting chamber 362 are both in a bell-mouth shape.

[0040] See also Figures 8 to 10 As shown, by setting the discharge pipe body 363 and the connecting chamber 362 to be trumpet-shaped, the two can be snap-connected to prevent the discharge pipe body 363 and the connecting piece 361 from separating under high pressure, and a second sealing ring 365 is set in the second sealing groove 364 to close the gap between the discharge pipe body 363 and the inner wall of the connecting chamber 362 to prevent water or gas from overflowing from the gap, and because the discharge pipe body 363 and the connecting piece 361 are rotatably connected and cooperate with the rotation of the outer shell 31, the water outlet direction can be controlled.

[0041] A hinge hole 356 is formed at the end of the driving rod 353 away from the upper core body 351 , and a pry bar 37 is hingedly connected to the end of the driving rod 353 through the hinge hole 356 .

[0042] The distance from the center of the hinge hole 356 to the end of the pry rod 37 is a, and the distance from the center of the hinge hole 356 to the top surface of the closing cover 33 when the valve core 35 is closed to the discharge connector 34 is b, and a>b.

[0043] See also Figure 5 When the valve core 35 needs to be manually lifted, it is only necessary to lift the handle of the pry bar 37 upward so that the other end contacts the closing cover 33 to form a lever, which makes it more convenient and labor-saving to lift the valve core 35 to release the sealing of the discharge joint 34.

[0044] The outer surface of the container body 1 is provided with a flange, which is convenient for grabbing when water needs to be added into the container body 1 or when water needs to be poured out.

[0045] The container body 1, the cover 2, the automatic pressure relief discharge device 3 and the liquid guide tube 4 are all made of stainless steel. Since the device is in a humid environment for a long time, the use of stainless steel is not easy to rust and the service life is increased.

[0046] The liquid guide tube 4 is a telescopic tube that can be extended or contracted. When cooking is needed, the liquid guide tube 4 only needs to be contracted, instead of being separated from the connecting portion 32 and taken out from the container body 1 each time cooking. This can prevent the liquid guide tube 4 from being contaminated due to excessive separation frequency. When boiling water, the liquid guide tube (4) only needs to be extended below the liquid surface. The specific structure of the liquid guide tube 4 can be a threaded connection, that is, two tubes are connected by threads to achieve telescopic connection, or two tubes can be plugged in, wherein the connection part can be interference fit with a sealing ring, which can refer to the method of the discharge tube body 363 and the connector 361.

[0047] The working process of the present invention is as follows: when boiling water, the end of the liquid guide tube 4 is located below the liquid level, and the pressure inside the container body 1 increases continuously after the water inside the container body 1 is boiled. When the pressure is greater than the elastic force of the spring 355 and the preset pressure of the gravity of the upper core body 351 and the lower core body 352, the upper core body 351 and the lower core body 352 are driven to move upward in the outer shell 31, and the blockage of the discharge joint 34 is released, so that the water inside the container body 1 can be guided downward by the liquid guide tube 4 and discharged from the discharge joint 34; when the pressure inside the container body 1 can make the water flow upward under the guidance of the liquid guide tube 4, the upper core body 351 and the lower core body 352 are driven to move upward in the outer shell 31, and the blockage of the discharge joint 34 is released, so that the water inside the container body 1 can be discharged from the discharge joint 34; when the pressure inside the container body 1 can make the water flow upward under the guidance of the liquid guide tube 4, the upper core body 351 and the lower core body 352 are driven to move upward in the outer shell 31, and the blockage of the discharge joint 34 is released, and the water inside the container body 1 can flow downward from the discharge joint 34; when the pressure inside the container body 1 can make the water flow upward under the guidance of the liquid guide tube 4, the upper core body 351 and the lower core body 352 are driven to move upward in the outer shell 31, and the blockage of the discharge joint 34 is released, and the upper core body 351 and the lower core body 352 are driven to move upward in the outer shell 31, and the blockage of the discharge joint 34 is removed, and the upper core body 351 and the lower core body 352 are driven to move upward in the outer shell 31, and the upper core body 351 and the lower When the flow is not enough to overcome the elastic force of the spring 355 and the gravity of the upper core 351 and the lower core 352, a person can manually lift the upper core 351 and the lower core 352 in the outer shell 31 through the pry bar 37 to release the blockage of the discharge joint 34. At this time, the pressure inside the container body 1 will discharge the water from the discharge joint 34 under the guidance of the liquid guide tube 4; when cooking, the liquid guide tube 4 can be retracted to be above the liquid level, and high-pressure gas will be discharged through the discharge joint 34. The specific automatic exhaust and manual exhaust are the same as the above principles and operations, and will not be described in detail here.

[0048] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
