Description

Technical Field

[0001] This invention relates to a cassette oven valve body. Background Technology

[0002] The existing cassette stove valve body has a complex structure. When used with stoves, the stoves require many stamped parts to be compatible with it, making stove installation difficult and increasing the cost of parts and finished products.

[0003] Furthermore, existing cassette stove valve bodies generally only have a single function of regulating air intake and exhaust. They need to be assembled together with a solenoid valve device, an igniter device, and a burner head to achieve the final flame formation.

[0004] Therefore, the assembly of a cartridge stove requires combining components such as the stove body, solenoid valve, igniter, and burner head, resulting in a long assembly time. Thus, it is very important to develop a cartridge stove valve body that integrates the functions of a solenoid valve and a control valve to save assembly time. Summary of the Invention

[0005] The purpose of this invention is to provide a compact cassette furnace valve body that integrates an igniter and a solenoid valve.

[0006] The objective of this invention is achieved as follows:

[0007] A cassette stove valve body includes a valve body, a regulating valve, a push plate, an igniter, a solenoid valve, a push rod for driving the solenoid valve, a torsion spring for driving the push rod, and a gas cylinder connector for connecting to a gas cylinder. The valve body is provided with an inlet chamber, an outlet chamber, a top chamber, a regulating chamber, and an exhaust chamber. The valve body has an air guide channel with an inlet hole and an outlet hole.

[0008] The inlet of the air inlet chamber is connected to the gas cylinder connector, the outlet of the air inlet chamber is connected to the inlet of the air outlet chamber, the outlet of the air outlet chamber is connected to the inlet of the top chamber, the outlet of the top chamber is connected to the air inlet of the air guide channel, the air outlet of the air guide channel is connected to the inlet of the regulating chamber, the outlet of the regulating chamber is connected to the inlet of the exhaust chamber, and the outlet of the exhaust chamber extends out of the valve body for connecting to the burner head.

[0009] The regulating valve is rotatably mounted inside the regulating chamber, with the control lever of the regulating valve extending out of the valve body. The rotation of the regulating valve controls the opening degree of the outlet of the regulating chamber.

[0010] The solenoid valve is sealed at one end of the air guide channel, and the inner end of the solenoid valve is provided with a valve plate for cutting off the passage between the air inlet and the air outlet. A first sealing ring is provided between the solenoid valve and the air guide channel.

[0011] The push rod is located at the other end of the air guide channel, and a second sealing ring and a first return spring are provided between the inner end of the push rod and the air guide channel;

[0012] The valve body has a mounting groove near the regulating valve, and the igniter is fixed in the mounting groove facing the regulating valve.

[0013] The push plate has a socket that matches the shape of the control lever. One end of the push plate is provided with a first pushing part, and the other end of the push plate is provided with a second pushing part. The first pushing part abuts against the igniter. The torsion spring is positioned outside the valve body by screws. One end of the torsion spring abuts against the top rod, and the other end of the torsion spring abuts against the second pushing part. The outer end of the solenoid valve is also provided with a thermocouple probe.

[0014] The valve body is equipped with an integrally formed gas guide channel, which has an inlet and an outlet. The solenoid valve can be directly installed in the gas guide channel, thus integrating the solenoid valve into the valve body. The valve body has a mounting groove in which the igniter is fixed, thus integrating the igniter into the valve body. When the regulating valve rotates, the first pushing part of the push plate rotates and touches and activates the igniter, and the second pushing part of the push plate rotates and touches the top rod and activates the solenoid valve. During the rotation of the regulating valve, the gas path is quickly connected, and the gas from the gas cylinder enters the burner head along the gas path, ensuring smooth gas discharge. At the same time, the igniter quickly ignites the gas at the burner head to form a flame. The gas ignition is rapid, enabling quick ignition of the cassette stove, which is convenient for users. Moreover, since the valve body integrates the igniter and solenoid valve, there is no need to assemble the igniter and solenoid valve separately during the assembly of the cassette stove, saving assembly time and improving the production efficiency of the cassette stove.

[0015] The objective of this invention can also be achieved by the following technical measures:

[0016] Furthermore, when the regulating valve rotates, it connects the outlet of the regulating chamber and the inlet of the exhaust chamber. Simultaneously, the second pushing part touches the torsion spring, thereby opening the solenoid valve. The solenoid valve connects the air inlet and outlet of the air guide channel. At the same time, the first pushing part of the regulating valve touches the igniter, which ignites the gas to form a flame. This rotation process facilitates both rapid connection of the gas path and rapid ignition, achieving rapid ignition of the gas and improving the ignition efficiency of the portable gas stove.

[0017] Furthermore, the gas cylinder connector is a magnetic gas cylinder connector. Using the magnetic gas cylinder connector, the user places the gas cylinder in the gas cylinder mounting cavity of the portable gas stove. The magnetic gas cylinder connector uses magnetic attraction to hold the gas cylinder together, allowing the gas cylinder and the magnetic gas cylinder connector to be quickly assembled together, making the gas cylinder assembly and disassembly simpler.

[0018] Furthermore, the valve body is provided with a limiting cavity corresponding to the position of the control lever. The limiting cavity has a first limiting port and a second limiting port. The push plate is placed in the limiting cavity. The first pushing part extends out of the first limiting port, and the first limiting port limits the rotation distance of the first pushing part. The second pushing part extends out of the second limiting port, and the second limiting port limits the rotation distance of the second pushing part.

[0019] The first limiting port restricts the rotation distance of the first pushing part to prevent the rotation position of the first pushing part from deviating and improves the accuracy of opening the igniter. The second limiting port restricts the rotation distance of the second pushing part to prevent the rotation position of the second pushing part from deviating and improves the accuracy of opening the solenoid valve.

[0020] Furthermore, it also includes a protective cover with an opening, the protective cover being fixed at the limiting cavity, the protective cover partially blocking the push plate, while the control lever extends out of the opening.

[0021] The protective cover prevents the push plate from becoming loose, greatly improving the stability of the cassette oven valve body.

[0022] The beneficial effects of this invention are as follows:

[0023] In this invention, the valve body is provided with an integrally formed gas guide channel, which has an inlet and an outlet. The solenoid valve can be directly installed in the gas guide channel, thus integrating the solenoid valve into the valve body. The valve body has a mounting groove in which the igniter is fixed, thus integrating the igniter into the valve body. When the regulating valve rotates, the first pushing part of the push plate rotates and touches and activates the igniter, and the second pushing part of the push plate rotates and touches the top rod and activates the solenoid valve. During the rotation of the regulating valve, the gas path is quickly connected, and the gas from the gas cylinder enters the burner head along the gas path, ensuring smooth gas discharge. At the same time, the igniter quickly ignites the gas at the burner head to form a flame. The rapid ignition of the gas enables quick ignition of the cassette stove, making it convenient for users. Moreover, since the valve body integrates the igniter and the solenoid valve, there is no need to assemble the igniter and solenoid valve separately during the assembly of the cassette stove, saving assembly time and improving the production efficiency of the cassette stove.

[0043] The push rod 51 is located at the other end of the air guide channel 7, and a second sealing ring 55 and a first return spring 56 are provided between the inner end of the push rod 51 and the air guide channel 7.

[0044] The valve body 1 has a mounting groove 8 near the regulating valve 2, and the igniter 4 is fixed in the mounting groove 8 facing the regulating valve 2;

[0045] The push plate 3 has a socket 31 that matches the shape of the control lever 21. One end of the push plate 3 is provided with a first pushing part 32, and the other end of the push plate 3 is provided with a second pushing part 33. The first pushing part 32 abuts against the igniter 4. The torsion spring 52 is positioned outside the valve body 1 by screws. One end of the torsion spring 52 abuts against the top rod 51, and the other end of the torsion spring 52 abuts against the second pushing part 33. The outer end of the solenoid valve 5 is also provided with a thermocouple probe (not shown in the figure).

[0046] Furthermore, when the regulating valve 2 rotates, it connects the outlet of the regulating chamber 14 and the inlet of the exhaust chamber 15. At the same time, the second pushing part 33 touches the torsion spring 52, thereby opening the solenoid valve 5. The solenoid valve 5 connects the air inlet 71 and the air outlet 72 of the air guide channel 7. Simultaneously, the first pushing part 32 of the regulating valve 2 touches the igniter 4, and the igniter 4 ignites the gas to form a flame.

[0047] Furthermore, the gas cylinder connector 6 is a magnetic gas cylinder connector 6.

[0048] Furthermore, the valve body 1 is provided with a limiting cavity 9 corresponding to the position of the control lever 21. The limiting cavity 9 has a first limiting port 91 and a second limiting port 92. The push plate 3 is placed in the limiting cavity 9. The first pushing part 32 extends out of the first limiting port 91, and the first limiting port 91 limits the rotation distance of the first pushing part 32. The second pushing part 33 extends out of the second limiting port 92, and the second limiting port 92 limits the rotation distance of the second pushing part 33.

[0050] A cartridge stove using the aforementioned cartridge stove valve body 1 includes a stove body (not shown in the figure), a burner head (not shown in the figure), and a knob (not shown in the figure). The burner head is installed in the stove body, and the cartridge stove valve body 1 is installed in the stove body. The exhaust chamber 15 outlet of the cartridge stove valve body 1 is connected to the air inlet of the burner head. The gas cylinder connector 6 of the cartridge stove valve body 1 extends into the gas cylinder mounting cavity of the stove body to connect to a gas cylinder (not shown in the figure). At the same time, the control lever 21 of the cartridge stove valve body 1 extends out of the stove body to connect to the knob.

[0051] Working principle:

[0052] The user turns the knob, which drives the regulating valve 2 to rotate via the control lever 21. The regulating valve 2 connects the outlet of the regulating chamber 14 and the inlet of the exhaust chamber 15. At the same time, during the rotation of the regulating valve 2, the second pushing part 33 of the push plate 3 touches the torsion spring 52. The torsion spring 52 pushes the top rod 51, causing the valve plate 53 of the solenoid valve 5 to move, resulting in the connection between the air inlet 71 and the air outlet 72 of the air guide channel 7. At the same time, during the rotation of the regulating valve 2, the first pushing part 32 of the push plate 3 touches the igniter 4, and the igniter 4 ignites the gas at the burner head to form a flame.

[0053] When the outlet of regulating chamber 14 and the inlet of exhaust chamber 15 are connected, and the air inlet 71 and the air outlet 72 of air guide channel 7 are connected, the gas cylinder passes through air inlet chamber 11, air outlet chamber 12, top chamber 13, regulating chamber 14 and exhaust chamber 15 and is finally discharged to the furnace head.

[0054] During the flame combustion process, the thermocouple probe is heated instantaneously, so that the valve plate 53 of the solenoid valve 5 remains in the open state (making the air inlet 71 and the air outlet 72 connected). When the flame is extinguished, the thermocouple probe cools down, the solenoid valve 5 resets, and the valve plate 53 cuts off the channel between the air inlet 71 and the air outlet 72, thereby cutting off the gas source and improving the safety of using the cassette stove.
