Detailed implementation manners

[0034] The following further elaborates on this application in conjunction with Figures 1-3 the attached drawings.

[0035] An embodiment of this application discloses a gasoline generator. Referring to Figure 1 , the gasoline generator includes a body 1 and an air guiding component 2. The body 1 includes a fan, a control panel, a cylinder head 12, a muffler 13, an exhaust pipe, and a support frame 11. The bottom of the support frame 11 abuts against the ground to form a support. The fan, the control panel, the cylinder head 12, the muffler 13, and the exhaust pipe are sequentially fixed on the surface of the support frame 11 by bolts. The air guiding component 2 is installed on the fan. The air guiding component 2 can guide the airflow generated by the fan to impact the control panel and the cylinder head 12, so as to cool the gasoline generator, thereby improving the heat dissipation efficiency of the gasoline generator.

[0036] Referring to Figure 1 , the air guiding component 2 includes an air guiding cover 21, an air guiding plate 22, fixing bolts 23, and a wind shield 24. The air guiding cover 21 is fixed on the surface of the fan by bolts. The inner cavity of the air guiding cover 21 shields the air outlet end of the fan. The surface of the air guiding cover 21 facing the control panel is provided with exhaust holes 211. The depth direction of the exhaust holes 211 penetrates the outer wall of the air guiding cover 21 and communicates with the inner cavity of the air guiding cover 21. The number of the fixing bolts 23 can be one, two, or more. In the embodiment of this application, the number of the fixing bolts 23 is multiple. The fixing holes for the ends of the fixing bolts 23 to pass through are spaced apart on the plate surface of the air guiding plate 22. The fixing bolts 23 correspond to the fixing holes one by one. The ends of the fixing bolts 23 pass through the fixing holes and are threadedly tightened and fixed on the surface of the air guiding cover 21. The air guiding plate 22 is not easily separated from the air guiding cover 21, so as to fix the air guiding plate 22 on the air guiding cover 21. The airflow generated by the operation of the fan is discharged through the exhaust holes 211. The plate surface of the air guiding plate 22 guides the airflow to impact the control panel, and the air exchanges heat with the control panel, so that the control panel is not easily damaged due to long-term operation at a high temperature, realizing the cooling of the control panel, thereby improving the cooling efficiency of the gasoline generator.

[0037] Referring to Figure 2 and Figure 3, the wind shield 24 covers the outer peripheral surface of the cylinder head 12. An air inlet flow channel 241 is formed on the surface of the wind shield 24 facing the exhaust air hole 211. The air inlet flow channel 241 is connected to the inner cavity of the wind shield 24. The air discharged from the exhaust air hole 211 enters the inner cavity of the wind shield 24 through the air inlet flow channel 241. The air exchanges heat with the outer peripheral surface of the cylinder head 12 to cool down the cylinder head 12. The wind shield 24 includes a first wind shield part 242 and a second wind shield part 243. The first wind shield part 242 and the second wind shield part 243 cover the outer peripheral surface of the cylinder head 12, and the air inlet flow channel 241 is located between the first wind shield part 242 and the second wind shield part 243. A positioning plate 3 is integrally formed and fixed on the surface of the first wind shield part 242 facing the cylinder head 12. A positioning groove 121 for the positioning plate 3 to be embedded is formed on the surface of the cylinder head 12. The surface of the positioning plate 3 can tightly abut against the inner wall of the positioning groove 121 to form a limit, so that the first wind shield part 242 is not easily displaced on the cylinder head 12, thereby improving the connection stability of the wind shield 24 on the cylinder head 12.

[0038] Refer to Figure 2 and Figure 3 , the first wind shield part 242 is fixed on the surface of the cylinder head 12 by bolts, so that the first wind shield part 242 is not easily separated from the cylinder head 12, thereby improving the limit stability of the first wind shield part 242 on the cylinder head 12. A guiding arc plate 4 is fixed on the surface of the muffler 13 facing the air inlet flow channel 241 by bolts. The surface of the guiding arc plate 4 guides the air to impact the surface of the exhaust pipe. The air exchanges heat with the surface of the exhaust pipe to cool down the exhaust pipe, thereby improving the cooling efficiency of the gasoline generator.

[0039] Refer to Figure 1 , a dust-proof cover 5 is fixed on the surface of the support frame 11 by bolts. The inner cavity of the dust-proof cover 5 shields the muffler 13, so that users are not easily scalded by the temperature of the muffler 13 when using the gasoline generator, thereby improving the safety of users when using the gasoline generator. A plurality of ventilation holes 51 are spaced apart on the surface of the dust-proof cover 5. The ventilation holes 51 penetrate through the outer wall of the dust-proof cover 5 in the depth direction and are connected to the inner cavity of the dust-proof cover 5. The air in the dust-proof cover 5 exchanges heat with the muffler 13 and then is discharged from the ventilation holes 51 to cool down the muffler 13, thereby improving the heat dissipation efficiency of the gasoline generator.

[0040] The implementation principle of a gasoline generator in an embodiment of this application is as follows: The airflow generated by the operation of the fan is discharged through the exhaust holes 211. The air flow guided by the guide plate 22 impacts the control panel, and heat exchange occurs between the air and the control panel, preventing the control panel from being damaged due to long-term operation at a high temperature, achieving cooling of the control panel, and thus improving the cooling efficiency of the gasoline generator. At the same time, the air discharged from the exhaust holes 211 enters the inner cavity of the wind shield 24 through the air inlet flow channel 241, and heat exchange occurs between the air and the outer peripheral surface of the cylinder head 12, achieving cooling of the cylinder head 12. Moreover, the air guided by the guide arc plate 4 impacts the surface of the exhaust pipe, and heat exchange occurs between the air and the surface of the exhaust pipe, achieving cooling of the exhaust pipe, further improving the cooling efficiency of the gasoline generator.

[0041] The above are all preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
