[0020] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0021] In the present application, unless otherwise stated, the orientation words contained in the terms "up, down, in, out" only represent the orientation of the term in the conventional use state, or the common name understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0022] AsFigures 1-3 An oil supply system of a cold fog machine, comprising: a plunger pump 3 and an oil inlet pipe 1 connected with the plunger pump 3 and inserted into a combustion chamber 4 at a tail end, wherein the tail end of the oil inlet pipe 1 is a porous structure 2.

[0023] In the above technical solution, the tail end of the oil inlet pipe 1 is provided with the porous structure 2, which can disperse fuel during spraying, significantly improve the atomization effect of the fuel, disperse the fuel into smaller particles, increase the contact area between the fuel and the air, and significantly improve the fuel atomization quality while reducing the cost.

[0024] The oil inlet pipe 1 is directly connected with the plunger pump 3, and the oil supply amount can be adjusted by adjusting the working frequency of the plunger pump 3, thereby improving the stability, simplifying the structure, reducing the overall equipment cost, and reducing the power consumption. In the prior art, the cold fog machine is usually powered by a battery, and the low power consumption can prolong the use time of the cold fog machine and increase the endurance of the cold fog machine. Moreover, the cost of subsequent maintenance and repair is low.

[0025] The oil inlet pipe 1 can be made of a special metal material, such as a stainless steel alloy that is resistant to high temperature and corrosion.

[0026] In a preferred embodiment of the application, the porous structure 2 comprises at least two oil outlets arranged at intervals.

[0027] In the above technical solution, the several oil outlets are arranged at intervals on the tail end of the oil inlet pipe 1, which can further increase the spraying range of the fuel and further improve the atomization effect of the fuel.

[0028] In a preferred embodiment of the application, the several oil outlets are arranged at intervals along the circumferential direction of the oil inlet pipe 1.

[0029] In the above technical solution, the oil outlets arranged at intervals along the circumferential direction of the oil inlet pipe 1 can further expand the spraying range of the fuel and further improve the atomization effect.

[0030] In a preferred embodiment of the application, the several oil outlets are uniformly distributed along the circumferential direction of the oil inlet pipe 1.

[0031] In the above technical solution, the uniformly distributed oil outlets can ensure that the fuel can uniformly cover a specific area of the combustion chamber 4 when sprayed, thereby improving the atomization effect.

[0032] The diameter of the oil inlet pipe 1, the diameter of the oil outlet and the number of the oil outlet are matched with the combustion chamber 4, for example, when the diameter of the combustion chamber 4 is 4mm, the number of the oil outlet is 2-4, and the diameter of the oil outlet is between 0.2mm-0.5mm, through reasonable matching, both the fuel injection speed and the oil droplet size after the fuel is sprayed can be ensured, which is beneficial to subsequent atomization.

[0033] In a preferred embodiment of the application, the oil inlet pipe 1 is welded or threaded or glued to the side wall of the combustion chamber 4.

[0035] In a preferred embodiment of the application, the oil injection direction of the oil outlet is perpendicular to the air inlet direction of the combustion chamber 4.

[0036] In the above technical solution, the fuel is vertically incident into the combustion chamber 4 from the oil inlet pipe 1, which can effectively utilize the shearing action of the airflow to significantly improve the atomization effect of the fuel. The shearing force of the airflow on the fuel is increased by 10%-20% when the fuel is vertically incident compared with the traditional single-hole oil inlet and non-vertical incident mode, which significantly improves the fuel atomization quality.

[0037] The preferred embodiments of the application are described in detail above in combination with the drawings, but the application is not limited to the specific details in the above embodiments. Within the technical concept of the application, various simple modifications can be made to the technical solution of the application, and these simple modifications all belong to the protection scope of the application.
