[0002] Pressure cookers are a common type of cookware, often used for outdoor picnics or kitchen cooking. They utilize the physical phenomenon that the boiling point of liquid increases under higher vapor pressure, allowing water to reach a higher temperature without boiling, thereby speeding up the efficiency of stewing food.

DETAILED DESCRIPTION

[0035] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0038] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0039] The valve body structure of the existing pressure valve generally includes a valve column, and the steam inlet of the valve column is located in the pot. When cooking, the food in the pot can easily block the steam inlet, making it impossible to release pressure, resulting in pressure accumulation in the pot and easily causing the pot to explode.

[0040] In order to solve the above problems, the present application proposes an anti-clogging pressure valve body structure, such as Figures 1 to 9 As shown, it includes a valve column 1, which includes a steam inlet end column 15 placed in the pot and a steam outlet end column 16 placed outside the pot. The valve column 1 is provided with a steam passage 11 passing through the steam inlet end column 15 and the steam outlet end column 16. The steam outlet end column 16 is provided with a steam outlet 13, and the steam outlet 13 is connected to the steam passage 11.

[0041] The end surface of the steam inlet end column 15 is provided with at least one steam inlet groove 17 , and the steam inlet groove 17 is connected to the steam outlet channel 11 ;

[0042] The steam inlet groove 17 extends from the end surface of the steam inlet end column 15 to the columnar body of the steam inlet end column 15 to form the steam inlet port 12 .

[0043] In this embodiment, the valve column 1 is installed on the pot cover, and the valve column 1 is surrounded by the steam inlet end column 15 and the steam outlet end column 16. When the pot cover is closed over the pot body, the steam inlet end column 15 is located inside the pot, and the steam outlet end column 16 is located outside the pot. The steam inlet end column 15 and the steam outlet end column 16 are integrally formed.

[0044] In this embodiment, the end face of the steam inlet end column 15 refers to the plane where the circular surface of the column is located. A steam inlet groove 17 is provided on the end face of the steam inlet end column 15. According to actual production requirements or steam outlet requirements, the steam inlet groove 17 can be set as one or more, and the steam inlet groove 17 on the end face of the steam inlet end column 15 will extend to the column of the steam inlet end column 15. For ease of understanding, it can be understood that the steam inlet groove 17 on the column of the steam inlet end column 15 is connected to the steam inlet groove 17 on the end face of the steam inlet end column 15;

[0045] Each steam inlet groove 17 is connected to the steam outlet passage 11 to form the steam inlet 12 of the steam inlet end column 15. The steam outlet 13 of the steam outlet end column 16 is connected to the steam outlet passage 11, which is equivalent to the steam inlet 12 being connected to the steam outlet 13 through the steam outlet passage 11. When pressure relief is performed, steam pressure can enter the steam outlet passage 11 from the steam inlet groove 17 at the end surface of the steam inlet end column 15 and / or from the steam inlet groove 17 at the column body of the steam inlet end column 15, rise along the steam outlet passage 11, and be discharged from the steam outlet 13.

[0046] When the food in the pot blocks the steam inlet groove 17 on the end face of the steam inlet end column 15, the steam pressure can also enter the steam outlet 11 from the steam inlet groove 17 where the column of the steam inlet end column 15 is located, and because the steam inlet groove 17 on the end face of the steam inlet end column 15 is blocked, the pressure on the steam inlet groove 17 where the column of the steam inlet end column 15 is located becomes greater, and at the same time, the pressure on the blocked steam inlet groove 17 will also increase. When the pressure on the steam inlet groove 17 where the column of the steam inlet end column 15 is located is greater than the steam inlet groove 17 on the end face of the blocked steam inlet end column 15, the steam inlet groove 17 on the column of the steam inlet end column 15 is used to block the steam inlet groove 17 on the end face of the steam inlet end column 15. The food forms an impact, and the food is washed back into the pot from the steam inlet groove 17 on the end face of the steam inlet end column 15, preventing the food from blocking the steam inlet groove 17 on the end face; similarly, when the steam inlet groove 17 on the column body of the steam inlet end column 15 is blocked, the steam inlet groove 17 on the end face or other unblocked steam inlet grooves 17 on the column body will also form an impact on the blocked steam inlet groove 17 on the column body, opening the blocked grooves; in other words, as long as all the steam inlet grooves 17 on the column body or end face of the steam inlet end column 15 are not blocked, the steam inlet port 12 will not be blocked, and the steam pressure can be used to enter the steam outlet channel 11 from the unblocked steam inlet groove 17 while impacting the blocked steam inlet groove 17.

[0047] In this embodiment, the steam inlet groove 17 on the end surface is extended to the column, thereby increasing the steam inlet area and preventing food from clogging. At the same time, the blocked steam inlet groove 17 can be quickly restored to normal under the impact of steam pressure.

[0048] Preferably, when the end surface of the steam inlet end column 15 is provided with a plurality of steam inlet grooves 17, the notches of each steam inlet groove 17 on one side of the middle portion of the end surface of the steam inlet end column 15 are connected to each other, so that the plurality of steam inlet grooves 17 are interconnected;

[0049] The notch of each steam inlet groove 17 on the side facing the end surface edge of the steam inlet end column 15 extends upward to the column body of the steam inlet end column 15 .

[0050] like Figure 5 As shown, in the first embodiment, when a steam inlet groove 17 is provided on the end surface of the steam inlet terminal column 15, the cross section of the steam inlet groove 17 on the end surface of the steam inlet terminal column 15 presents a straight hole shape;

[0051] like Figure 6 As shown, in the second embodiment, when two steam inlet grooves 17 are formed on the end surface of the steam inlet end column 15, the cross section of the steam inlet groove 17 on the end surface of the steam inlet end column 15 is V-shaped, and the notches at one end of the two steam inlet grooves 17 intersect, and the notches at the other end of the two steam inlet grooves 17 that do not intersect extend toward the column body;

[0052] like Figure 7 As shown, in the third embodiment, when three steam inlet grooves 17 are formed on the end surface of the steam inlet end column 15, the cross section of the steam inlet grooves 17 on the end surface of the steam inlet end column 15 presents a Y-shape, where the notches at one end of the three steam inlet grooves 17 intersect, and the notches at the other end of the three steam inlet grooves 17 that do not intersect extend toward the column body;

[0053] like Figure 8 and Figure 9 As shown, in the fourth embodiment, when four steam inlet grooves 17 are formed on the end surface of the steam inlet end column 15, the cross section of the steam inlet grooves 17 on the end surface of the steam inlet end column 15 presents an X-shape or a cross-shape, and the notches at one end of the four steam inlet grooves 17 intersect with each other, while the notches at the other end of the four steam inlet grooves 17 that do not intersect extend toward the column body;

[0054] In actual production, the above four embodiments can all achieve the effect of preventing blockage and clearing blockages of the present technical solution, but the cross-shaped, X-shaped, Y-shaped or V-shaped ones require more processes during production and processing than the straight hole-shaped steam inlet groove 17. Therefore, this embodiment takes embodiment 1 as the optimal embodiment.

[0055] Preferably, it also includes a valve cap 2 and a valve core 3;

[0056] The end surface of the steam outlet 13 of the steam outlet end column 16 is recessed toward the steam passage 11 to form a receiving cavity 14. The wall surface of the receiving cavity 14 is inclined relative to the steam passage 11. The steam outlet 13 is provided at the bottom of the receiving cavity 14 so that the receiving cavity 14 is connected to the steam passage 11.

[0057] The valve bonnet 2 is provided with a locking cavity for locking the accommodating cavity 14. The top of the valve bonnet 2 is provided with a steam dissipation port 22 communicating with the locking cavity. A steam dissipation space 21 is left between the accommodating cavity 14 and the steam dissipation port 22.

[0058] The abutting portion of the valve core 3 is provided with a cone 31 , and the conical surface of the cone 31 abuts against the wall surface of the accommodating cavity 14 so that the cone 31 is placed in the accommodating cavity 14 and can movably seal the steam passage 11 ;

[0059] The mounting portion of the valve core 3 is installed with a spring 4;

[0060] In the steam outlet state, steam pressure enters the steam outlet channel and pushes up the valve core 3 to open the steam outlet channel 11 so that the steam outlet channel 11 is connected to the steam dispersion space 21. The steam pressure forms a spiral cyclone under the action of the spring 4. The spiral cyclone travels back and forth between the steam dispersion space 21 and overflows from the steam dispersion port 22.

[0061] In this embodiment, the valve body structure is composed of three components: a valve column 1, a valve cap 2 and a valve core 3. The valve column 1 is a column structure, and a steam inlet 12 and a steam outlet 13 are respectively opened at both ends of the column. A steam passage 11 is opened between the steam inlet 12 and the steam outlet 13, that is, inside the column. One end of the steam inlet 12 is located inside the pot, and one end of the steam outlet 13 is located outside the pot. When cooking, if the pressure in the pot has not reached a certain level, the pressure valve cannot pass steam to avoid the pot from leaking. Insufficient pressure can cause food to not be cooked thoroughly. Therefore, in this embodiment, a receiving chamber 14 is provided at one end of the steam outlet 13 of the valve column 1. A valve core 3 is placed in the receiving chamber 14 to seal the steam passage 11. Only when the pressure in the pot reaches a critical value, the steam pressure from the steam inlet 12 pushes the valve core 3 upward along the steam passage 11, opening the steam outlet 13, so that the steam passage 11 is connected to the steam dissipation space 21, and the steam pressure is released to the outside of the pot through the steam dissipation port 22 of the steam dissipation space 21.

[0062] Furthermore, in this embodiment, an accommodating cavity 14 is formed by recessing one end of the valve column 1 toward the steam passage 11, and the wall surface of the accommodating cavity 14 is designed to be an inclined surface to match the conical surface structure of the cone 31 of the valve core 3, so that the cone 31 of the valve core 3 can be embedded in the accommodating cavity 14 and block the steam passage 11; at the same time, because the wall surface of the accommodating cavity 14 is inclined and the cone 31 of the valve core 3 has a taper, when the steam pressure pushes up the valve core 3, the gas will enter the steam dissipation space 21 at a certain oblique angle along the conical surface and the inclined wall surface of the accommodating cavity 14; as the steam pressure continues to increase, the gap between the valve core 3 and the accommodating cavity 14 increases, more and more gas enters the steam dissipation space 21 and the oblique angle of entry becomes larger, and the gas begins to diffuse in all directions along the taper of the cone 31, forming an airflow in the steam outlet 13;

[0063] When the airflow from the steam outlet 13 enters the steam dispersion space 21 upward, due to the presence of the spring 4, the airflow will form a spiral cyclone under the spiral structure of the spring 4 and rise in the steam dispersion space 21; because the steam dispersion port 22 is arranged at the top of the steam dispersion space 21, the cyclone needs to continue to rise along the steam dispersion space 21 and can only be depressurized to the outside after contacting the steam dispersion port 22 at the top. Therefore, to a certain extent, the time for the gas to be depressurized and overflowed is delayed, so that the steam pressure with fragrance can be retained longer.

[0064] Because the steam outlet 22 is located at the top, the cyclone is forced to overflow only from the top. In addition, the presence of the spring 4 occupies a portion of the steam dispersion space 21, resulting in only a portion of the cyclone overflowing from the steam outlet 22. The remaining cyclone will hit the top and fall back. Because the steam pressure is output intermittently, the valve core 3 is constantly pushed up, causing the steam outlet 13 to continuously have air pressure entering the steam dispersion space 21. The cyclone that hits the top and falls back is re-formed under the spiral structure of the spring 4, and then continuously travels back and forth in the steam dispersion space 21 and overflows from the steam outlet 22.

[0065] Furthermore, the steam diffusion port 22 of this embodiment is set on the top of the valve cap 2, and there is only one. Compared with the existing situation where the steam diffusion port 22 is set on both sides of the valve cap 2 and there are multiple steam diffusion ports 22, the single steam diffusion port 22 can slow down the steam diffusion speed, so that the fragrance can be retained longer.

[0066] Preferably, the cone 31 includes a cone body portion 311 and a cone tip portion 312;

[0067] The conical surface corresponding to the conical tip 312 contacts the wall surface corresponding to the lower portion of the accommodating cavity 14, and the conical tip 312 is inserted into the steam passage 11;

[0068] A gap is formed between the conical surface corresponding to the conical body portion 311 and the wall surface corresponding to the upper portion of the accommodating cavity 14 .

[0069] In this embodiment, the conical tip 312 extends from the steam outlet 13 into the steam passage 11 to seal the steam passage 11 to prevent pressure leakage when the pressure in the pot is insufficient, thereby preventing food from being cooked.

[0070] Furthermore, the conical surface of the cone body 311 and the upper wall surface of the accommodating chamber 14 are not completely matched, but form a certain gap. From the cross-sectional view, an angle is formed between the straight lines of the two, and the intersection of the angle is the contact point between the cone tip 312 and the steam outlet 13. The reason for this design is that after the cone tip 312 is lifted up, the steam pressure can enter the steam dispersion space 21 along the gap, and the entry angle is constantly increasing. With the conical surface of the cone tip 312 and the inclined wall surface of the accommodating chamber 14, 360-degree omnidirectional diffusion can be formed. If the inclination angle of the wall surface of the accommodating chamber 14 is designed to match the conical surface of the cone 31, the cone 31 needs to be completely lifted up and separated from the accommodating chamber 14 to smoothly discharge steam, which will also cause the steam output to be too small and unable to form a cyclone.

[0071] Preferably, one end of the spring 4 is fixed to the mounting portion of the valve core 3 , and the other end abuts against the steam diffusion port 22 .

[0072] In one embodiment of the present application, one end of the spring 4 is fixed to the mounting portion of the valve core 3, and the other end abuts against the steam dispersion port 22. Under this design, the steam pressure will lift the valve core 3, causing the valve core 3 to squeeze the spring 4. When the steam pressure increases, the force of the valve core 3 squeezing the spring 4 will increase, and the valve core 3 will move away from the accommodating chamber 14. When the steam pressure decreases, the force of the valve core 3 squeezing the spring 4 will decrease. At the same time, due to the reaction force of the spring 4, the valve core 3 will approach the accommodating chamber 14. At the same time, because the spring 4 is abutting against the steam dispersion port 22, when the cyclone is about to overflow from the steam dispersion port 22, the spring 4 will slow down the speed of the cyclone overflow, making the fragrance last longer.

[0073] That is, the spring 4 abuts against the steam dispersing port 22, which is equivalent to reducing the speed of the airflow dispersing from the steam dispersing port 22, thereby making the fragrance remain longer in disguise.

[0074] Preferably, one end of the spring 4 is fixed to the mounting portion of the valve core 3 , and a reciprocating distance is reserved between the other end and the steam dispersion port 22 .

[0075] In another embodiment of the present application, one end of the spring 4 is fixed to the mounting portion of the valve core 3, and the other end does not abut against the steam dispersion port 22, and a reciprocating distance is retained between the two. Under this design, the valve core 3 and the spring 4 can both rise driven by the airflow until the spring 4 abuts against the steam dispersion port 22, and the valve core 3 squeezes the spring 4 to cause the spring to deform. After the steam pressure is weakened, and under the reaction of the spring 4, the spring 4 and the valve core 3 descend. Compared with the embodiment in which the spring 4 directly abuts against the steam dispersion port 22, the cyclone of this embodiment will overflow from the steam dispersion port 22 more and at a faster speed, but the fragrance retention effect is slightly inferior to the previous embodiment.

[0076] Preferably, the mounting portion includes a clamping block 32 , one end of the spring 4 is inserted into the clamping block 32 , and the middle portion of the clamping block 32 protrudes outward in a circular direction to clamp the spring 4 .

[0077] In one embodiment of the present application, the connection method between the spring 4 and the valve core 3 can be: a clamping block 32 is designed at the installation part of the valve core 3, the spring 4 is inserted into the clamping block 32, and the middle part of the clamping block 32 is used to protrude in an annular direction to clamp the spring 4 to prevent the spring 4 from detaching from the valve core 3.

[0078] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
