In this embodiment, the number of electric heating elements 3 is two, the two electric heating elements 3 are provided between a lower surface of the gasification chamber 1 and the base 4, and the lower surface of the gasification chamber 1 and the base 4 completely enclose the electric heating elements 3. The gasification chamber 1 is further provided with a gasification chamber liquid inlet port 12 communicating with a lower surface of the gasification chamber inner cavity 11. Several cooling fins 13 are further provided in the gasification chamber inner cavity 11, and the cooling fins 13 are connected to the lower surface of the gasification chamber inner cavity 11 and are arranged close to the heating elements 3. Channels 14 for liquid circulation are provided between a plurality of fins 13 and between the fins 13 and an inner wall of the gasification chamber inner cavity 11.

In this embodiment, the gasification chamber lid 2 is further provided with two gas outlet ports 21. The gas outlet ports 21 are connected to a gas outlet pipe 8, the other end of the gas outlet pipe 8 is connected to a burner of a product, and the gas outlet pipe 8 is made of a non-metal pipe having low thermal conductivity. The electric heating elements 3 are connected to the controller 5. The controller 5 can control the operation of the electric heating elements 3, and common heating rods may be adopted as the electric heating elements 3.

[0022] Referring to FIGS. 1 and 2, the temperature detecting device 7 is provided inside the gasification chamber inner cavity 11 and mounted on the gasification chamber lid 2. The temperature detecting device 7 is connected to the controller 5, and a common temperature detecting probe may be adopted as the temperature detecting device 7.

[0023] Referring to FIGS. 1, 2, and 5, the liquid level control chamber 6 is provided with a liquid level detecting device 61 connected to the controller 5. The liquid level detecting device 61 is provided with four liquid level detecting probes, i.e., a safety liquid level detecting probe 611, a low liquid level detecting probe 612, a middle liquid level detecting probe 613, and a high liquid level detecting probe 614 in sequence from bottom to top. The safety liquid level detecting probe 611 is higher than the lowest point of the lower surface of the gasification chamber inner cavity 11, the low liquid level detecting probe 612 is higher than the electric heating elements 3, and the high liquid level detecting probe 614 is lower than upper surfaces of the cooling fins 13. The liquid level control chamber 6 is provided with a liquid level control chamber liquid outlet port 62. The liquid level control chamber liquid outlet port 62 and the gasification chamber liquid inlet port 12 are connected through a gasification chamber liquid inlet pipe 15. The gasification chamber liquid inlet pipe 15 is arranged so as not to be higher than the liquid level control chamber liquid outlet port 62 and/or the gasification chamber liquid inlet port 12, that is, the gasification chamber 1 and the liquid level control chamber 6 form a set of communicating vessels, and the liquid level of the gasification chamber inner cavity changes synchronously with the liquid level in the liquid level control chamber 6. The liquid level control chamber 6 is further provided with a liquid level control chamber liquid supply port 63. The liquid level control chamber liquid supply port 63 is connected to a liquid supply pipe 64 for supplying liquid fuel to the gasification device of the present embodiment, and the inner diameter of the gasification chamber liquid inlet pipe 15 is much larger than the inner diameter of the liquid supply pipe 64.

[0024] Referring to FIGS. 1, 2, and 4, the gasification device further comprises an overflow liquid storage chamber 9. An overflow pipe 91 is provided on the overflow liquid storage chamber 9, an overflow port 65 is provided on the liquid level control chamber 6, the overflow liquid storage chamber 9 is connected to the overflow port 65 through the overflow pipe 91, and the overflow liquid storage chamber 9 is provided below the overflow port 65. A liquid level alarm device 92 is provided below a side surface of the overflow liquid storage chamber 9, and the liquid level alarm device 92 is connected to the controller 5. The liquid level alarm device 92 is known in the art, and will not be described again. A vent 93 is further provided at the top of the overflow liquid storage chamber 9.

[0025] Referring to FIGS. 1 and 2, the gasification device further includes a liquid return pump 10. The liquid level control chamber 6 is provided with a liquid level control chamber liquid return port 66, the liquid return pump 10 is connected to the liquid level control chamber liquid return port 66 through a liquid return pump liquid inlet pipe 101, and an outlet of the liquid return pump 10 is connected to a fuel storage device of the product through a liquid return pump liquid outlet pipe 102.

[0026] The operating principle of this embodiment is as follows:

[0027] In operation, the liquid level control chamber 6 is supplied with liquid at a constant average rate through the liquid supply pipe 64, and when the liquid level in the liquid level control chamber 6 is above a safety level, the controller 5 controls the electric heating elements 3 to start heating. Since the gasification chamber inner cavity 11 communicates with the liquid level control chamber 6, and the inner diameter of the gasification chamber liquid inlet pipe 15 is much larger than the inner diameter of the liquid supply pipe 64, the liquid level in the gasification chamber inner cavity 11 is always the same as the liquid level in the liquid level control chamber 6. The liquid fuel in the gasification chamber inner cavity 11 is gasified under the heating action of the electric heating elements 3. The controller 5 adjusts the heating power of the electric heating elements 3 in real time according to the change of the liquid level detected by the liquid level detecting device 61, so that the liquid level in the liquid level control chamber 6 is always between the high liquid level detecting probe 614 and the low liquid level detecting probe 612. Since the gasification chamber 1 in this embodiment is made of material having high thermal conductivity such as aluminum or copper, and the cooling fins 13 are provided in the gasification chamber inner cavity 11, the liquid fuel in the gasification chamber inner cavity 11 is heated more uniformly, and the gasification process is more stable and controllable. Moreover, the average rate at which the liquid is supplied through the liquid supply pipe 64 is constant, so the average rate at which the gaseous fuel is supplied to the outside through the gas outlet pipe 8 is also constant, making the flame combustion more stable. By providing the temperature detecting device 7, it is possible to ensure that the temperature in the gasification chamber inner cavity 11 is always within a controllable range to avoid the explosive boiling of the liquid fuel. The gas outlet pipe 8, which is not made of metal, can also prevent the heat of the burner from being transferred to the gasification chamber 1, so that the heating control of the gasification chamber 1 is more precise and stable.

[0028] When the operation is finished, the liquid fuel remaining in the liquid level control chamber 6 and the gasification chamber 1 can be pumped back to a fuel storage container by the liquid return pump 10, so that the liquid fuel is prevented from being stored in the gasification chamber 1 and the liquid level control chamber 6 for a long time when the product is not in operation.

[0029] When the liquid level detecting device 61 malfunctions and the liquid overflows from the overflow port 65 of the liquid level control chamber 6, the overflown liquid fuel can flow to the overflow liquid storage chamber 9 through the overflow pipe 91 for storage, and the liquid level alarm device 92 can timely feed back a signal to the controller 5 to provide an alarm and stop the liquid supply of the liquid supply pipe 64 and the heating operation of the electric heating elements 3. The liquid return pump 10 executes an end program. In addition, by providing the vent 93, the pressure in the overflow liquid storage chamber 9 is balanced with the outside, so that the pressure does not increase due to the continuous inflow of the liquid fuel. Since the overflow port 65 communicates with the overflow liquid storage chamber 9, the overflow port 65 may serve as a breathing port of the liquid level control chamber 6. Therefore, the pressure in the liquid level control chamber 6 does not increase due to continuous inflow of the liquid, thereby ensuring smooth operation of the entire device.

[0030] In the gasification device for a gasification combustion fireplace provided in this embodiment, by adding the cooling fins to the gasification chamber inner cavity, the gasification process of the liquid fuel is heated more uniformly, effectively solving the problems in the prior art that the liquid fuel in the gasification chamber is heated and gasified non-uniformly and the explosive boiling phenomenon easily occurs, so that the liquid fuel can be stably supplied to the burner for combustion, and the flame stability is greatly improved. The problems of instability and easy explosive boiling in the alcohol gasification process of the existing alcohol fuel gasification combustion fireplace are overcome.

[0031] The preferred implementations of the present disclosure are merely described above. It should be noted that, for those of ordinary skill in the art, several improvements and modifications can also be made without departing from the technical principles of the present disclosure, and these improvements and modifications should also be regarded as the scope of protection of the present disclosure.
