Technical Field

The invention relates to the technical field of stoves, in particular to a novel biogas stove which is well sealed based on airflow.

Background

The methane stove is one of new energy devices, has been widely popularized and used at present, belongs to an atmospheric type stove, and consists of four parts, namely a nozzle, an air adjusting plate, an ejector and a head part, wherein the nozzle is a key part for controlling the flow (namely load) of methane and converting the pressure energy of the methane into kinetic energy and is generally made of metal materials (preferably copper).

At present, current marsh gas kitchen, lean on the negative pressure from the intake pipe to inhale air and gas mixture, the combustion head has a section of horizontal tail pipe and head up, be covered with the vertically hole of giving vent to anger on the head, the not enough of this kind of structure is, when the gas-cooker will be closed and use, the flame that is burning enters into the intake pipe along the gas easily, produce the tempering at the intake pipe head easily, thereby probably lead to the condition that the intake pipe burns, give people's normal use, great potential safety hazard has been brought, the safety of guarantee people is not convenient for.

In order to solve the above problems, the inventor proposes a novel biogas stove sealed based on airflow, which has the advantage that after use, the gas outlet at the upper end of the gas inlet pipe can completely isolate the outflow of biogas, so as to avoid the situation that the head of the gas inlet pipe is tempered due to the burning flame entering the gas inlet pipe along with the fuel gas.

Disclosure of Invention

The invention adopts the following technical scheme for realizing the technical purpose: a novel biogas stove sealed based on airflow comprises: the kitchen body, the last fixed surface of the kitchen body installs the mount, the lower fixed surface of the kitchen body installs the intake pipe, the inside of intake pipe is provided with the gas baffle, and the last fixed mounting of gas baffle has the dead lever, and the middle part of the upper end fixed mounting of dead lever has the connecting rod to peg graft and has the fixed ball, the inside fixed mounting of mount has the retainer plate, and the lower extreme fixed mounting of retainer plate has the fixed block, and the department of protrusion fixed mounting of fixed block has the air nozzle, the lower fixed surface of fixed block installs the moisture absorption plate, the internal both ends fixed mounting of kitchen has two symmetrical oxygen removal pieces.

Furthermore, the diameter of the air baffle is matched with the inner diameter of the air inlet pipe, and the air baffle is mainly used for enabling upward methane to open the upper end of the air inlet pipe and discharge the methane.

Furthermore, the middle upper end of the air inlet pipe is made of elastic metal, the upper end of the air inlet pipe is arranged in a staggered mode, the sealing performance of the air inlet pipe is mainly improved, the transverse plate arranged in a staggered mode at the upper end of the air inlet pipe is in a sawtooth shape, and the smooth flowing of biogas can be guaranteed when the upper end of the air inlet pipe is jacked open by the fixing ball.

Furthermore, the diameter that is less than the lower extreme in intake pipe middle part, and the diameter at intake pipe middle part is less than the diameter of gas shield, mainly is when pushing up the upper end of intake pipe in order to guarantee the fixed ball, avoids the whole outside that runs out the intake pipe of fixed ball.

Furthermore, the upper surface fixed mounting of air baffle has the piece of ventilating, mainly is when avoiding air baffle to the middle part of intake pipe, can have the air current to pass through, avoids air baffle to plug up the air current.

Furthermore, the distance from the air baffle to the middle part of the air inlet pipe is not more than the diameter of the fixed ball, and the fixed ball is mainly used for ensuring that the fixed ball cannot completely slide outside the air inlet pipe of the cutter.

Furthermore, the middle upper end of the air inlet pipe is provided with a groove matched with the fixed ball, and the groove is mainly used for storing the fixed ball.

Furthermore, the thrust of the airflow generated in the air inlet pipe is greater than the gravity of the air baffle plate, the fixed rod, the connecting rod and the fixed ball, and the thrust is mainly used for pushing the air baffle plate, the fixed rod, the connecting rod and the fixed ball.

The invention has the following beneficial effects:

1. This novel marsh gas kitchen sealed based on air current, through the intake pipe, the gas baffle, the dead lever, the connecting rod is used with the cooperation of fixed ball, can utilize the marsh gas air current to flow out through the fixed ball with the upper end of intake pipe from the intake pipe and open, let marsh gas emit, when no, the upper end of intake pipe can be closed, the upper end of avoiding the intake pipe produces the tempering, possess and can be after finishing using, the gas outlet of intake pipe upper end can completely cut off the advantage of marsh gas outflow, the flame of having avoided the burning easily enters into the intake pipe along the gas by the negative pressure, lead to the intake pipe head to produce the condition of tempering.

2. This novel marsh gas kitchen sealed based on air current uses through the cooperation of hygroscopic plate and deoxidization piece, can keep the internal environment's of kitchen dry, avoids the metal of intake pipe to wet the wet oxidation, and the use through the deoxidization piece simultaneously can guarantee the internal relative anaerobic environment of kitchen, does not have the condition that oxygen or oxygen are not enough through the assurance for the upper end of intake pipe is difficult to produce the tempering.
