To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined purposes, the following detailed description of the embodiments of the present invention is provided with the accompanying drawings and the preferred embodiments.
Referring to fig. 1 and fig. 2, an embodiment of the present invention provides a novel energy-saving gas stove adjusting valve device, including:
a shutoff valve 1, an air inlet 11 being formed in the shutoff valve 1;
a proportional valve 2, a first air vent 21 is formed between the proportional valve 2 and the stop valve 1;
a pulse valve 3, the pulse valve 3 having an upper cavity 31 and a lower cavity 32 therein, the upper cavity 31 having a frame 33 therein, an iron core 34 disposed inside the frame 33 and inserted into the lower cavity 32, a coil 35 sleeved on the periphery of the frame 33, a permanent magnet 36 disposed at one end of the coil 35 and located on the periphery of the iron core 34, an iron core cap 37 disposed inside the lower cavity 32 and connected to the end of the iron core 34, and a spring 38 sleeved on the periphery of the iron core 34 and located between the inner wall of the lower cavity 32 and the iron core cap 37, the lower cavity 32 having a first valve port 321 therein, the end of the iron core cap 37 being disposed opposite to the first valve port 321; a second vent 322 is formed between the proportional valve 2 and the lower chamber 32, and a vent 12 is formed in the pulse valve 3.
The cut-off valve 1 of the present embodiment functions as a master valve for controlling intake air. Specifically, the stop valve 1 controls whether or not the gas introduced from the gas inlet 11 can be introduced into the proportional valve 2 through the first gas port 21. The specific structure and working principle of the stop valve 1 are the same as those of the conventional stop valve in the field.
The proportional valve 2 is used for adjusting the fire of the stove. The specific structure and operation principle of the proportional valve 2 are the same as those of the proportional valve which is conventional in the field.
The pulse valve 3 is used for controlling the opening and closing of fire outside the stove. Specifically, when the pulse valve 3 is opened, the outer ring fire is started to ignite; when the impulse valve 3 is closed, the outer ring fire is extinguished, leaving only the center fire.
The working principle of the pulse valve 3 in the embodiment is as follows:
when the outer ring fire needs to be opened, a directional voltage is input to the coil 35 through the control circuit, the voltage can be set to be a positive voltage or a negative voltage, a magnetic field is generated after the coil 35 is electrified, and the magnetic pole of the coil 35 is the same as that of the permanent magnet 36, the magnetic field generated by the coil 35 is superposed with the magnetic field of the permanent magnet 36, so that strong magnetic attraction is generated on the iron core 34, the iron core 34 is moved towards a direction away from the first valve port 321 instantly by the strong magnetic attraction, the spring 38 is compressed, at this time, as shown in fig. 2, the first valve port 321 is opened, the gas can pass through the first valve port 321, and the outer ring fire is opened and. Then, the control circuit stops inputting the voltage to the coil 35, the magnetic field generated by the coil 35 disappears, the permanent magnet 36 continuously magnetizes the iron core 34, the magnetic attraction force to the iron core 34 is maintained, the iron core 34 is kept still, at this time, the first valve port 321 is continuously opened, and the external ring fire is kept in the opened state. It can be seen that, when the first valve port 321 is maintained in the open state, that is, the outer ring fire is maintained in the open state, the pulse valve 3 does not need to be energized, and the pulse valve 3 is in the deenergized state, so that the consumption of electric energy is greatly reduced.
When the outer ring fire needs to be closed, a reverse voltage is input to the coil 35 through the control circuit, the voltage is just opposite to the voltage input when the outer ring fire is opened, a magnetic field is generated after the coil 35 is electrified, and the magnetic pole of the coil 35 is opposite to the magnetic pole of the permanent magnet 36, the magnetic attraction of the permanent magnet 36 to the iron core 34 is counteracted by the magnetic field generated by the coil 35, the iron core 34 moves towards the first valve port 321 under the action of the elastic restoring force of the spring 38, the iron core cap 37 blocks the first valve port 321, at this time, as shown in fig. 3, the first valve port 321 is closed, the gas cannot pass through the first valve port 321, and the outer ring fire is closed and extinguished. Then, the control circuit stops inputting voltage to the coil 35, the magnetic field generated by the coil 35 disappears, the magnetic attraction force of the permanent magnet 36 to the iron core 34 cannot trigger the iron core 34 to move, the iron core 34 maintains the static state, at this time, the first valve port 321 is continuously closed, and the external fire maintains the closed state. As can be seen, when the first valve port 321 is maintained in the closed state, that is, the outer ring fire is maintained in the closed state, it is not necessary to energize the pulse valve 3, and the pulse valve 3 is in the deenergized state, so that the consumption of electric energy is greatly reduced.
The control circuit of the present embodiment is used to input forward and reverse voltages to the coil 35, as shown in fig. 7. The control circuit inputs diametrically opposite voltages to the coil 35, so that after the coil 35 is energized to generate a magnetic field, two different functions are achieved: firstly, the magnetic pole of the coil 35 is the same as that of the permanent magnet 36, so that the magnetic field generated by the coil 35 is superposed with that of the permanent magnet 36, so as to generate strong magnetic attraction to the iron core 34, and the strong magnetic attraction causes the iron core 34 to instantly move in a direction away from the first valve port 321, so that the first valve port 321 is opened; secondly, the magnetic pole of the coil 35 is opposite to the magnetic pole of the permanent magnet 36, so that the magnetic field generated by the coil 35 cancels the magnetic attraction of the permanent magnet 36 to the iron core 34, the iron core 34 moves towards the first valve port 321 under the action of the elastic restoring force of the spring 38, the iron core cap 37 blocks the first valve port 321, and the first valve port 321 is closed.
As can be seen from the above, in the present embodiment, by the structural design of the pulse valve 3 with the permanent magnet 36 added, in combination with the control circuit capable of supplying forward and reverse voltages to the coil, the pulse valve 3 only needs to be energized when opening and closing the pulse valve, and does not need to be energized when the pulse valve 3 is kept in operation, thereby greatly reducing the power consumption. Therefore, the power of the whole regulating valve body device is reduced, the heat generation is reduced, a transformer with smaller power can be selected, and the cost is reduced.
When the pulse valve 3 is opened, the iron core 34 moves upwards due to the strong magnetic attraction, in order to position the iron core 34, a positioning member 39 located right above the iron core 34 is arranged on the inner upper wall of the upper cavity 31, and for the installation of the positioning member 39, an installation convex block 393 clamped into the inner upper wall of the upper cavity 31 is arranged at the upper end of the positioning member 39. Specifically, as shown in fig. 2, 3 and 6, a positioning boss 391 is protruded from one end of the positioning member 39 facing the iron core 34, and a positioning groove 392 is recessed in the positioning boss 391. Meanwhile, as shown in fig. 5, a recess 341 for the positioning boss 391 to be engaged is concavely disposed on an end of the iron core 34 close to the positioning member 39, and a positioning protrusion 342 corresponding to the positioning groove 392 is disposed in the recess 341. When the iron core 34 moves upward due to the strong magnetic attraction, the positioning protrusion 342 of the iron core 34 is caught in the positioning groove 392 of the positioning member 39, and the positioning boss 391 of the positioning member 39 is caught in the recess 341 of the iron core 34, thereby positioning the iron core 34 and preventing the displacement thereof.
In order to enable the iron core 34 to vertically move up and down when in action, in the embodiment, a guide shaft sleeve 40 located in the framework 33 is longitudinally arranged in the upper cavity 31, and the iron core 34 and the positioning element 39 are arranged in the guide shaft sleeve 40. The iron core 34 can move vertically up and down in the guide sleeve 40 when actuated.
For the installation of the permanent magnet 36, in the embodiment, an accommodating groove 331 is formed at the lower end of the framework 33, and the permanent magnet 36 is disposed in the accommodating groove 331, as shown in fig. 2 and 4.
For the installation of the spring 38, in this embodiment, an upper limit boss 323 is disposed at the top of the inner side of the lower cavity 32 in a downward protruding manner, a lower limit boss 371 located right below the upper limit boss 323 is disposed on the iron core cap 37, the upper end of the spring 38 is sleeved on the periphery of the upper limit boss 323, and the lower end of the spring is sleeved on the periphery of the lower limit boss 371. Under the cooperation of upper limit boss 323 and lower limit boss 371, the mounting position and the elastic deformation range of spring 38 are limited, which is favorable for the iron core 34 to be acted on by the elastic restoring force of spring 38 when pulse valve 3 is closed, so that the iron core 34 can move toward first valve port 321 quickly to close first valve port 321.
The working principle of the stove regulating valve body device of the embodiment is as follows: when the stove is opened, the stop valve 1, the proportional valve 2 and the pulse valve 3 are fully opened, and then the fire power can be adjusted through the proportional valve 2. When the fire power is adjusted to be smaller than a set value, a pulse signal is sent to the control circuit, the control circuit is used for electrifying the coil 35, the pulse valve 3 is turned off, the outer ring fire is extinguished, and only the central fire is left; when the fire power is adjusted to be larger than the set value through the proportional valve 2, a pulse signal is sent to the control circuit, the control circuit energizes the coil 35, the pulse valve 3 is opened, and the external ring fire is ignited.
The invention also provides an outer ring fire control method based on the novel energy-saving gas stove adjusting valve body device, which comprises the following steps:
(1) opening the outer ring fire:

(1.2) next, the control circuit stops inputting voltage to the coil 35, the magnetic field generated by the coil 35 disappears, the permanent magnet 36 continuously magnetizes the iron core 34, the magnetic attraction force to the iron core 34 is maintained, the iron core 34 is made to be still, at this time, the first valve port 321 is continuously opened, and the external ring fire is maintained to be in an open state;
(2) closing the outer ring fire:
(2.1) inputting reverse voltage to the coil 35 through the control circuit, generating a magnetic field after the coil 35 is electrified, wherein the magnetic pole of the coil 35 is opposite to the magnetic pole of the permanent magnet 36, the magnetic field generated by the coil 35 cancels the magnetic attraction of the permanent magnet 36 to the iron core 34, the iron core 34 moves towards the first valve port 321 under the action of the elastic restoring force of the spring 38, the iron core cap 37 blocks the first valve port 321, at this time, the first valve port 321 is closed, and the external fire is closed;
