[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0031] Figure 1 This invention provides a schematic diagram of the structure of an oxygen pumping device according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the physical structure of the oxygen-boosting device provided in this embodiment of the present invention, which is configured in a gas stove. This embodiment is applicable to situations where the secondary oxygen supply is adjusted in real time based on the surface temperature of the burner head. The oxygen-boosting device can be configured in a gas stove.

[0032] like Figure 1 and Figure 2 As shown, the oxygenation device is installed on a gas stove with a secondary oxygen replenishment structure. The oxygenation device includes a fire level control valve body 1, a temperature sensing module 2, an oxygen generator 3, and a controller 4. The fire level control valve body 1, the temperature sensing module 2, and the oxygen generator 3 are electrically connected to the controller 4.

[0033] The firepower level control valve body 1 is used to output the current firepower level of the burner 5 after receiving the ignition command of the gas stove and controlling the burner 5 of the gas stove to work, and to feed back the current firepower level to the controller 4.

[0034] The temperature sensing module 2 is used to detect the surface temperature of the burner head of the burner 5 in real time and feed the surface temperature of the burner head back to the controller 4;

[0035] The controller 4 is used to control the oxygen blowing rotation state of the oxygen blower 3 according to the current fire level and the surface temperature of the burner head, and to control the oxygen blower 3 to provide secondary oxygen to the burner 5 based on the oxygen blowing rotation state.

[0036] The temperature sensing module 2 can detect the surface temperature of the burner head in real time, determine the working status of the burner 5, and control the secondary oxygen supply of the burner 5 in combination with the working status of the burner 5. The temperature sensing module 2 can be implemented using various existing temperature sensors, and this embodiment does not impose any special restrictions on it.

[0037] It is known that the larger the firepower of the gas stove and the higher the surface temperature of the burner, the more secondary oxygen is needed. Therefore, the controller 4 selects the amount of secondary oxygen to be supplemented based on the feedback of the surface temperature of the burner from the temperature sensing module 2. The set relationship between the surface temperature of the burner and the amount of secondary oxygen to be supplemented can be pre-set according to experience or other means, and the present embodiment does not make any limitation on this.

[0038] It can be understood that one, two or more temperature sensing modules 2 can be provided to obtain more accurate surface temperature of the burner. Similarly, one, two or more oxygen boosters 3 can be provided to obtain better adjustment of the amount of secondary oxygen and more sufficient oxygen. The present embodiment does not make any limitation on the number of temperature sensing modules 2 and oxygen boosters 3.

[0039] The firepower level control valve body 1 can have multiple levels, and the firepower level value that the firepower level control valve can output is a large fire level, a medium fire level, a small fire level and an off fire level. Therefore, the current firepower level includes a large fire level, a medium fire level, a small fire level and an off fire level.

[0040] In the present embodiment, the firepower level control valve body 1 outputs the corresponding level according to the received control instruction. Specifically, the large fire combustion control instruction of the burner 5 is received, and the current firepower level of the burner 5 is output as a large fire level by the firepower level control valve body 1.

The small fire combustion control instruction of the burner 5 is received, and the current firepower level of the burner 5 is output as a small fire level by the firepower level control valve body 1. The off fire combustion control instruction of the burner 5 is received, and the current firepower level of the burner 5 is output as an off fire level by the firepower level control valve body 1.

[0041] Specifically, the controller 4 outputs corresponding instructions according to the current firepower level value, and further controls the rotation and shutdown of the oxygen booster 3, and can control the rotation speed of the oxygen booster 3, so as to realize the oxygen booster 3 providing appropriate oxygen for the burner 5 to supplement the secondary oxygen.

[0042] In the present embodiment, the temperature sensing module 2 monitors the working state of the burner 5, and feeds back to the controller 4 whether the burner 5 is in a cold state or a hot state. In combination with the current firepower level value output by the firepower level control valve body 1, the controller 4 matches and outputs the corresponding fan speed of the oxygen booster 3, i.e. the oxygen booster 3 outputs the oxygen of the secondary oxygen to be supplemented.

[0043] Correspondingly, the controller 4 is used to control the oxygen booster 3 to be in a closed oxygen state when the current firepower level of the burner 5 output by the firepower level control valve body 1 is a small fire level or an off fire level.

[0047] If the set temperature range in which the furnace head surface temperature detected by the temperature sensing module 2 is located is the third large fire temperature range, the oxygen blowing rotating state of the oxygen blower 3 is controlled as the low-speed oxygen blowing state, and optionally, the third large fire temperature range can be that the furnace head surface temperature is greater than or equal to 120℃ and less than 180℃.

[0049] If the set temperature range in which the furnace head surface temperature detected by the temperature sensing module 2 is located is the fifth large fire temperature range, the oxygen blowing rotating state of the oxygen blower 3 is controlled as the closed oxygen blowing state, and optionally, the fifth large fire temperature range can be that the furnace head surface temperature is less than 80℃ to room temperature.

[0053] If the set temperature range in which the temperature of the furnace head surface detected by the temperature sensing module 2 is the third medium fire temperature range, the rotating state of the oxygen blowing machine 3 is controlled to be the closed oxygen blowing state, and optionally, the third medium fire temperature range can be that the temperature of the furnace head surface is less than 180 DEG C to room temperature.
