Working principle:

the cigarette lighter 4 heats and carbonizes the biomass particles B in a contact heating mode, and the controller 7 controls factors such as the steering and the rotating speed of the motor in the hot air assembly A and the temperature of the cigarette lighter 4 to enable the flowing direction of the combustion-supporting airflow D to be reciprocal to the burning direction F of the biomass particles B. Specifically, the motor rotates anticlockwise to generate horizontal reverse high-temperature hot air C, and the carbonization propagation direction and speed of biomass particles B are effectively further controlled by controlling the wind speed of the high-temperature hot air C, so that the biomass particles B are fully smoldered with oxygen.

In the smoking system of the smoking furnace, the ignition cigarette rod 4 is arranged to ignite the biomass particles B, the biomass particles B are effectively controlled to enter a smoldering state, the biomass particles B in the smoldering state continuously burn but cannot generate flame, the combustion process is weak, and the combustion process can occur and be maintained in an environment with lower temperature and lower heat; the biomass particles B in the smoldering state can generate enough smoke E, so that the smoking effect of food materials is greatly improved, and the requirements of consumers on smoking flavor foods are met; in addition, in the combustion chamber, the flowing direction of the combustion-supporting airflow D is in reciprocal with the combustion direction F of the biomass particles B, so that the biomass particles B further enter a horizontal reverse smoldering state (the horizontal reverse smoldering state is characterized in that the moving direction of a combustion reaction area is opposite to the moving direction of an oxidant such as air, and the like, and the combustion process is slowly propagated due to the limitation of the air propagation speed, so that the required oxygen amount is less), and the horizontal reverse smoldering can prevent the biomass particles B from being excessively combusted to generate excessive smoke E, and meanwhile, the generation of open flame is avoided to ensure the safety. The smoking furnace burns smoking materials by using the horizontal reverse smoldering principle, so that the smoking efficiency is high, the smoking time is prolonged, enough smoke and heat can be generated, and further, obvious smoking effect and heating effect are obtained, the safety is high, and the user experience is good.

Further, the cigarette lighting rod 4 at least partially stretches into the combustion cavity 301, and the cigarette lighting rod 4 is far away from the air inlet end 3011, so that on one hand, the biomass particles B can be ensured to smoothly enter a horizontal reverse smoldering state, and on the other hand, the combustion-supporting air flow D can be prevented from influencing the operation of the cigarette lighting rod 4; the biomass particles B are positioned between the cigarette lighting rod 4 and the air inlet end 3011, and are ensured to enter a horizontal reverse smoldering state; the cigarette lighter rod 4 is at least partially in contact with the biomass particles B for efficient, rapid ignition of the biomass particles B.

Further, the combustion chamber 301 is provided with a first side wall 303, a second side wall 304 and a top wall 305 which are matched with each other in an opposite manner; the cigarette lighting rod 4 is close to the first side wall 303, so that the cigarette lighting rod 4 starts to ignite the biomass particles B from one side of the combustion cavity 301, and further the biomass particles B are controlled to burn to the other side of the combustion cavity 301; the air inlet end 3011 is arranged on the second side wall 304, and the air inlet end 3011 is a through hole structure of the second side wall 304; biomass particles B are located between the first side wall 303 and the second side wall 304; the top wall 305 is located at the top between the first side wall 303 and the second side wall 304, the air outlet end 3012 is disposed on the top wall 305 (or on the first side wall 303), and the air outlet end 3012 is a through hole structure of the top wall 305 and is arranged from the first side wall 303 to the second side wall 304. In the present embodiment, the flow direction of the combustion-supporting airflow D is from the second side wall 304 to the first side wall 303, and the combustion direction F is from the first side wall 303 to the second side wall 304, i.e. the combustion-supporting airflow D is reciprocal to the combustion direction F, so that the biomass particles B enter a reverse smoldering state.

By controlling the temperature of the combustion chamber 301, on one hand, the biomass particles B are kept smoldering and catch fire or flameout, and on the other hand, the smoldering of the biomass particles B can be prevented from being transited to open fire.

The temperature controller 8 can be a kick temperature controller and an electronic thermistor temperature controller:

1. jump type temperature controller: when the temperature of the cigarette lighting rod 4 is increased or decreased, the corresponding heat is transferred to the bimetal disc of the kick temperature controller; when the set action temperature of the kick temperature controller is reached, the kick temperature controller rapidly acts, and contacts are opened or closed through an internal mechanical structure, so that the purpose of switching on or switching off a circuit is achieved, and the on-off of the circuit is controlled; in the snap-action temperature controller, when the temperature of the disc-shaped sheet made of bimetal (by using a sealing cover to transfer heat) rises (or falls) to the action temperature, snap-action is generated instantaneously, and the action is transferred to the elastic movable contact support by the ceramic action rod; the movable contact and the fixed contact are respectively riveted on the movable contact bracket and the ox horn, and the movable contact and the fixed contact are separated after the movable contact bracket is pushed by the action rod, so that a circuit is disconnected; when the temperature is reduced to the recovery temperature of the dished bimetallic strip, the bimetal instantaneously recovers the original shape, the pressure applied to the action rod is eliminated, and the movable contact and the fixed contact recover the shape, so that the circuit is completed. Specifically, in the normal working state, the temperature controller 8 is in a normally closed state, so that a circuit between the cigarette lighting rod 4 and the controller 7 is in a passage, and the cigarette lighting rod 4 is heated normally; when the temperature controller 8 detects that the temperature of the cigarette lighting rod 4 exceeds about 140 ℃, the temperature controller 8 jumps; when the heating of the cigarette lighting rod 4 is stopped until the temperature controller 8 detects that the temperature of the cigarette lighting rod 4 is reduced to about 120 ℃, the temperature controller 8 is closed again, and the cigarette lighting rod 4 works again; the above actions are performed reciprocally; the controller 7 can monitor the temperature of the cigarette lighter 4 through the temperature controller 8, so as to control the temperature in the combustion chamber 301;

2. electronic thermistor temperature controller: the electronic thermistor temperature controller is arranged at a position close to the cigarette lighting rod 4, so as to detect the temperature of the periphery of the cigarette lighting rod 4; the specific working flow is as follows: detecting the temperature around the cigarette rod 4, comparing the temperature of the electronic thermistor temperature controller (comparing the self set temperature with the measured temperature), calculating the output deviation of the electronic thermistor temperature controller, and controlling the heating or switching-off operation quantity by the controller 7, wherein the working procedures are continuously circulated.

Besides the above-described scheme of controlling the temperature by providing the temperature controller 8, the following scheme is also possible:

the controller 7 is provided with a timing module for recording time and a temperature control program for controlling the cigarette rod 4; the temperature control program sets heating time and cooling time; when the time recorded by the timing module reaches the heating time in the state that the cigarette lighting rod 4 is electrified, the temperature control program controls the cigarette lighting rod 4 to be powered off; when the time recorded by the timing module reaches the cooling time in the power-off state of the cigarette lighting rod 4, the temperature control program controls the cigarette lighting rod 4 to be electrified so as to achieve the heating or cooling effect. Specifically, the temperature control program is programmed with a heating time (heating operation time of the cigarette rod 4) and a cooling time (stop cooling time of the cigarette rod 4); when the time recorded by the timing module reaches the heating time, the temperature control program sends an instruction to stop the cigarette rod 4, and the timing module starts to record the cooling time; when the time recorded by the timing module reaches the cooling time, the temperature control program sends an instruction to start the cigarette lighting rod 4, and the timing module reckons and records the heating time; the temperature control program controls based on the set time so that the cigarette lighter 4 can be continuously circulated within the set temperature range.
