A safe and ultra-thin valve body structure and a cooking stove

Abstract

The present invention provides a safe and ultra-thin valve body structure and a cooking stove, including a valve seat and a valve core disposed within the valve seat. The valve seat is provided with a gas inlet, a valve core installation space, an intake air passage, and a plurality of outlet air passages. The intake air passage is respectively communicated with the gas inlet and the valve core installation space, and the outlet air passage is communicated with the valve core installation space. The valve core is conical and disposed within the valve core installation space. The valve core is provided with a plurality of air holes corresponding to the outlet air passages. The valve core installation space forms a conical space. Gas enters from the end with a larger diameter of the valve core installation space, passes through the valve core, and then enters the outlet air passage through the air holes. By changing the air passage of the valve seat entering the valve core installation space, the sealing between the valve core and the valve core installation space is achieved, preventing fire leakage at the valve rod, avoiding the rigid collision between the warped rod and the solenoid valve, preventing damage to the solenoid valve, and reducing the maintenance cost.

Description

Technical Field

[0001] The present invention relates to a safe and ultra-thin valve body structure and a cooking stove. Background Art

[0002] Gas stoves have been widely used in families. Among them, the cock is an important component in the gas stove. The structure is that gas enters the valve core through the bottom of the valve core installation space and then is shunted from the air holes of the valve core into the air outlet airway. The center of the valve core of the cock has a thimble for starting the solenoid valve. The thimble pushes downward to drive the lever of the cock to close the solenoid valve so that the gas is connected. In this process, the gas enters from the lower end of the valve core. When the gas pressure is greater, the gas will push the thimble upward, causing the gas to leak in the gap between the thimble and the valve core, resulting in gas leakage. More seriously, it will cause fire leakage at the knob or even burns and fires, posing a great potential safety hazard. At the same time, due to the rigid collision between the lever and the solenoid valve, it is easy to damage the solenoid valve. When the distance between the lever and the solenoid valve is not precise enough, it will also cause the solenoid valve to close halfway and the gas to not pass completely. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a safe and ultra-thin valve body structure and a cooking stove, aiming to solve the problem of gas leakage from the center of the valve core of the cock and the problem of the rigid cooperation between the lever of the cock and the solenoid valve.

[0004] To achieve the above purpose, the present invention adopts the following solutions:

[0005] A safe and ultra-thin valve body structure includes a valve seat and a valve core arranged in the valve seat. A gas inlet, a valve core installation space, an air inlet airway, and multiple air outlet airways are arranged on the valve seat. The air inlet airway is respectively connected to the gas inlet and the valve core installation space, and the air outlet airway is connected to the valve core installation space. The valve core is conical and arranged in the valve core installation space. The valve core is provided with multiple air holes corresponding to the air outlet airways. The valve core installation space forms a conical space, and the gas enters from the end with a larger diameter of the valve core installation space, passes through the valve core, and then enters the air outlet airway through the air holes.

[0006] In one or more embodiments, a valve rod is arranged on the valve seat. A first conical tooth is arranged at the bottom end of the valve rod, and a second conical tooth meshing with the first conical tooth is arranged at the non-air inlet end of the valve core.

[0007] In one or more embodiments, a ventilation component is further provided. The ventilation component includes a crank, an L-shaped swing rod, and a solenoid valve. The solenoid valve is disposed between the gas inlet and the intake air passage. The swing rod is disposed at the suction end of the solenoid valve. The crank is connected to the swing rod. The crank is disposed at the lower end of the valve stem. When the valve stem drives the crank to rotate and further drives the swing rod to swing, the suction end of the solenoid valve is compressed, so that the gas inlet and the intake air passage are communicated.

[0008] In one or more embodiments, a push rod is disposed between the swing rod and the solenoid valve, and a spring is disposed between the push rod and the suction end of the solenoid valve. The swing head of the swing rod pushes the push rod to move in the suction direction of the solenoid valve, and further pushes the suction end of the solenoid valve to move in the suction direction.

[0009] In one or more embodiments, a return spring is disposed below the crank. The return spring is disposed between the crank and the bottom surface of the valve seat.

[0010] In one or more embodiments, the non-intake end of the valve core is solid, and a semi-circular mounting post is disposed at the non-intake end to connect the second conical tooth.

[0011] In one or more embodiments, the valve seat is provided with air holes corresponding to the air outlet passage. At least two air holes are provided. Correspondingly, at least two air holes are provided on the valve core.

[0012] A cooker includes the above-mentioned safe and ultra-thin valve body structure.

[0013] Beneficial effects: The present invention provides a safe and thin valve body structure and a cooker. By changing the air passage of the valve seat entering the installation space of the valve core, the valve core and the installation space of the valve core are sealed in the air flow direction, completely eliminating the safety hazard of fire leakage at the valve stem of the traditional cock valve body. At the same time, the rigid collision between the toggle lever and the solenoid valve is avoided. After the toggle lever is worn due to long-term use, the phenomenon that the solenoid valve cannot be opened or the solenoid valve cannot be opened in place is avoided, resulting in the inability to fire normally, the damage of the solenoid valve is avoided, the maintenance cost is reduced, and the service life of the product is extended.

[0020] The following further describes the solution of the present application in conjunction with the accompanying drawings:

[0021] Embodiment:

[0022] See the attached Figure 1-6 As shown in the figure, a safe and ultra-thin valve body structure includes a valve seat 1 and a valve core 2 disposed in the valve seat 1. A gas inlet 11, a valve core installation space 14, an intake air passage 12, and multiple outlet air passages 13 are provided on the valve seat 1. The intake air passage 12 communicates with the gas inlet 11 and the valve core installation space 14 respectively. The outlet air passage 13 communicates with the valve core installation space 14. The valve core 2 is conical and disposed in the valve core installation space 14. The valve core 2 is provided with a plurality of air holes 21 corresponding to the outlet air passages 13. The valve core installation space 14 forms a conical space. Gas enters from the end with a larger diameter of the valve core installation space 14, passes through the valve core 2, and then enters the outlet air passage 13 through the air holes 21. When the gas enters from the end with a larger diameter of the valve core installation space 14, it pushes the valve core 2 to move in the length direction of the valve core 2, so that the valve core 2 fits more closely with the valve core installation space 14 to form a seal. The greater the pressure of the gas, the closer the valve core 2 fits with the valve core installation space 14, and the better the sealing effect. At the same time, since the non-intake end of the valve core 2 is solid, the gas can only be discharged from the air holes 21, avoiding the safety hazard of gas leakage from the center of the valve core of the traditional cock valve. The structure is safe and reliable.

[0023] Preferably, the valve seat 1 is further provided with a bottom cover 16.

[0024] Furthermore, a valve rod 3 is provided on the valve seat 1. A first conical tooth 31 is provided at the bottom end of the valve rod 3. A second conical tooth 22 meshing with the first conical tooth 31 is provided at the non-intake end of the valve core 2. By the cooperation of the first conical tooth 31 and the second conical tooth 22, the longitudinal connection of the valve rod and the valve core of the traditional cock valve is changed into a transverse connection, greatly reducing the height of the valve body. Under the condition that the height of the valve core remains unchanged and the strength and service life of the valve core are ensured, the height of the valve body is greatly compressed to form an ultra-thin valve body.

[0025] Further, it is also provided with a ventilation component 4, which includes a crank 41, an L-shaped swing rod 42, and a solenoid valve 43. The solenoid valve 43 is arranged between the gas inlet 11 and the intake air passage 12. The swing rod 42 is arranged at the suction end of the solenoid valve 43. The crank 41 is connected to the swing rod 42. The crank 41 is arranged at the lower end of the valve stem 2. When the valve stem 2 drives the crank 41 to rotate and then drives the swing rod 42 to swing, the suction end of the solenoid valve 43 is compressed, so that the gas inlet 11 and the intake air passage 12 are communicated.

[0026] Preferably, a semi-circular mounting hole is provided on the crank 41, and a mounting post matching the semi-circular mounting hole is provided on the swing rod 42.

[0027] Further, a push rod 45 is arranged between the swing rod 42 and the solenoid valve 43, and a spring 46 is arranged between the push rod 45 and the suction end of the solenoid valve 43. The swing head of the swing rod 42 pushes the push rod 45 to move in the suction direction of the solenoid valve 43, and then pushes the suction end of the solenoid valve 43 to move in the suction direction. The push rod 45 with a spring 46 is arranged between the swing rod 42 and the solenoid valve 43, which avoids the rigid collision between the swing rod 42 and the solenoid valve 43, avoids the damage of the solenoid valve caused by the rigid collision, improves the service life of the solenoid valve 43, and reduces the maintenance cost.

[0028] Further, a return spring 44 is arranged below the crank 41. The return spring 44 is arranged between the crank 41 and the bottom surface of the valve seat 1 to make the crank 41 and the valve stem 3 return to their original positions.

[0029] Further, the non-intake end of the valve core 2 is solid, and a semi-circular mounting post is arranged at the non-intake end to connect the second conical tooth 22.

[0030] Further, the valve seat 1 is provided with air outlet holes 15 corresponding to the air outlet passage 13. At least two air outlet holes 15 are provided. Correspondingly, at least two air holes 21 are provided on the valve core 2.

[0031] Preferably, three air outlet holes 15 and three air outlet passages 13 are provided on the valve seat 1, and three air holes 21 are provided on the valve core 2 to form a three-ring flame.

[0032] A cooker includes the above-mentioned safe and ultra-thin valve body structure.

[0033] The above preferred embodiments should be regarded as examples of the implementation manners of the application scheme. All technical deductions, substitutions, improvements, etc. that are identical, similar to or based on the application scheme should be regarded as the protection scope of this patent.
