[0033] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0034] like Figures 1 to 6 As shown, a novel portable heater includes a housing 1, a burner 2, and a gas supply assembly 3. The burner 2 is installed on one side of the housing 1, and a flow guiding assembly 4 is also installed on the housing 1. The flow guiding assembly 4 is located on the upper side of the burner 2.

[0035] Specifically, the flow guiding component 4 includes a first flow guiding plate 401. One side of the first flow guiding plate 401 is connected to the outer wall of the housing 1. The first flow guiding plate 401 is located on the upper side of the burner 2 and guides the rising hot air generated by combustion to the outside of the burner 2.

[0036] The flow guiding assembly 4 also includes a second flow guiding plate 403, which is disposed inside the housing 1 and is connected to the inner wall of the housing 1 on one side and extends into the housing 1;

[0037] The second guide plate 403 is placed on the upper side of the burner 2 and an exhaust port 5 is provided on the housing 1 between the second guide plate 403 and the burner 2.

[0038] The exhaust port 5 is located on the upper side of the first guide plate 401, and one end of the second guide plate 403 is connected to the upper side of the exhaust port 5.

[0039] Furthermore, the first guide plate 401 is set as a first inclined plate 402 that gradually rises from the inside to the outside, and the second guide plate 403 gradually slopes downward from the inner wall of the shell 1 to the inner side to form a second inclined plate 404. By reasonably designing the tilt angle and position of the guide plate, the hot airflow can be distributed more evenly and smoothly to the front of the heater, improving heating efficiency and avoiding local overheating.

[0040] Furthermore, a housing guide structure 11 is provided on the upper side of the connection between the second inclined plate 404 and the housing 1, which is in the same inclination direction as the second inclined plate 404 and recessed inward, to further optimize the guidance of hot airflow, ensure that hot airflow can be discharged smoothly, and reduce the retention of heat in the housing.

[0041] Furthermore, a third guide plate 405 is installed on the rear side of the burner 2. The third guide plate 405 includes a mounting plate 406 located on the rear side of the burner 2. A third guide plate 407 is provided on the upper side of the mounting plate 406. One side of the third guide plate 407 is connected to the mounting plate 406, and the other side is connected to the upper side of the exhaust port 6 on the housing 1.

[0042] The third guide plate 407 is placed on the upper side of the second guide plate 403, and the gap between the mounting plate 406 and the tail end of the second guide plate 403 forms an airflow channel 408.

[0043] The first guide plate 401, the second guide plate 403, the third guide plate 407, and the mounting plate 406 are all provided with baffles 409 on both sides.

[0044] In this embodiment, the first guide plate 401 is connected to the outer wall of the housing 1 on one side and is located on the upper side of the burner 2. It guides the rising hot air flow generated by combustion to the front side of the burner 2 to form the first inclined plate 402, which guides the hot air flow to the front side of the burner and avoids the heat from concentrating on the upper housing. Both sides of the first guide plate 401 are provided with baffles 409 to prevent the hot air flow from overflowing and to ensure that the hot air flow is concentrated and guided to the front side of the burner.

[0045] The second guide plate 403 is located inside the housing 1, with one side connected to the inner wall of the housing 1 and extending into the housing 1 to form a second inclined plate 404. An exhaust port 5 is provided on the housing 1 between the second guide plate 403 and the burner 2 to facilitate the discharge of hot air generated by the burner 2 inside the housing 1. Baffles 409 are provided on both sides of the second guide plate 403 to further guide the hot airflow and ensure that the hot airflow is discharged smoothly.

[0046] The third guide plate 405 is installed on the rear side of the burner 2 and includes a mounting plate 406 and a third guide plate 407. The third guide plate 407 is provided on the upper side of the mounting plate 406. The gap between the mounting plate 406 and the tail end of the second guide plate 403 forms an airflow channel 408, which is used to discharge the residual hot gas during the combustion process of the burner 2. Baffles 409 are provided on both sides of the third guide plate 407 and the mounting plate 406 to further guide the hot airflow to be discharged from the exhaust port 6.

[0047] The third guide component 405 forms a semi-enclosed structure with the first guide plate 401 and the second guide plate 403 of the burner 2, further optimizing the direction of the hot airflow and ensuring that the hot airflow can be discharged to the front side from the exhaust port 6, exhaust outlet 5 and ceramic plate 202, reducing the heat retention in the shell. At the same time, it guides the hot airflow to the same direction and ensures that the hot airflow is concentrated and directed to the front side of the burner 2, preventing the upper shell of the heater from getting too hot, and improving heating efficiency and safety.

[0048] In this embodiment, the hot airflow generated by the combustion of the burner 2 flows upward through the first guide plate 401 and forward. The exhaust port 5 of the second guide plate 403 is located above the first guide plate 401. According to Bernoulli's principle, the airflow velocity is fast on the lower side of the first guide plate 401, and a negative pressure zone is formed correspondingly above the first guide plate 402. Since the exhaust port 5 is located above the first guide plate 402 and the air at the exhaust port 5 is relatively circulating, the air above the first guide plate 401 will flow away in the direction of the hot airflow from the combustion of the ceramic plate 202 below, ensuring that the hot airflow is concentrated and directed to the front of the burner 2. At the same time, the hot air generated by the internal components of the burner 2 can also flow out from the exhaust port 5 through the guidance of the second guide plate 403, reducing the heat retention in the shell 1 and concentrating the hot airflow in the same direction.

[0049] In this embodiment, through the coordinated action of the first guide plate 401, the second guide plate 403, and the exhaust port 5, during the combustion process of the burner 2, the air above the first guide plate 401 follows and replenishes the airflow below the first guide plate 401, ensuring that the hot airflow below the first guide plate 401 flows smoothly out of the first guide plate 401 in the direction of exhaust, avoiding phenomena such as the hot airflow moving vertically upward, uneven heat distribution, excessively high temperature on the upper side of the shell, increased risk of burns, and reduced heating efficiency.

[0050] Furthermore, the burner 2 includes a burner head 201, which is embedded in the housing 1. A ceramic plate 202 is provided on the outside of the burner head 201. A first guide plate 401, a second guide plate 403, and a third guide plate 407 are all installed on the upper side of the ceramic plate 202 and guide the rising hot airflow generated by the combustion of the ceramic plate 202 to the outside of the ceramic plate 202.

[0051] Furthermore, the burner 2 also includes an ejector tube 203, which is inserted into the burner head 201 from the outside to the inside for gas supply. An ignition device 7 is also provided on the outside of the burner head 201 for rapid ignition.

[0052] A protective net 8 is installed on the outside of the burner 2 to prevent users from being burned.

[0053] The outer side of the housing 1 is provided with a recessed gas tank connection structure 9. The gas supply component 3 includes a gas tank 301, a valve body 302 and a control switch 303. The valve body 302 and the control switch 303 are located on the upper side of the gas tank connection structure 9. The lower side of the gas tank connection structure 9 is provided with an opening 10. The gas tank 301 is connected to the valve body 302 from bottom to top through the opening 10 and is placed on the outer side of the housing 1 for easy operation by the user.

[0054] This invention, through the design of the flow guide component 4, directs the hot airflow generated by combustion to the front of the burner 2, avoiding heat concentration in the upper shell 1, improving heating efficiency, reducing the temperature of the upper shell, lowering the risk of burns, and improving safety. The design of its inclined flow guide plate and airflow channel 408 optimizes airflow circulation, improves the ventilation performance of the heater, and reduces the accumulation of harmful gases.

[0055] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
