Description

Technical Field:

[0001] The present utility model relates to the field of vehicle auxiliary heaters, and particularly to an air intake mechanism for a new energy vehicle auxiliary heater. Background Art:

[0002] A vehicle auxiliary heater is an on-vehicle heating device independent of the vehicle engine, which can preheat and warm up the vehicle engine and cab parked in a cold environment in winter without starting the engine. The parking heater is very beneficial to the cold start of the vehicle in a low-temperature environment. Nowadays, in cold regions of our country, the parking heater has become a standard configuration for various vehicles.

[0003] The working principle of the vehicle auxiliary heater is as follows: Combustion-supporting air enters the heater through the air intake system, mixes with the fuel in the heater to form a combustible mixture, then catches fire and burns to form a heating flame that enters the combustion cylinder, and heat transfer is achieved through the heat exchange system to achieve the purpose of rapid preheating and warming up. However, the current parking heaters have the following disadvantages: When the combustion-supporting air enters the heater, due to the disordered air flow and convective impact, combustion occurs before it is fully mixed with the fuel in the heater, resulting in incomplete combustion, and harmful particles, nitrogen oxides, carbon monoxide and other emissions in the exhaust gas cannot be effectively controlled, which is not conducive to environmental protection. Summary of the Invention:

[0004] The purpose of the present utility model is to provide an air intake mechanism for a new energy vehicle auxiliary heater, which solves the problem that in the prior art, when the combustion-supporting air enters the heater, due to the disordered air flow and convective impact, combustion occurs before it is fully mixed with the fuel in the heater, resulting in incomplete combustion, and harmful particles, nitrogen oxides, carbon monoxide and other emissions in the exhaust gas cannot be effectively controlled, which is not conducive to environmental protection.

[0021] The present utility model will be further described in detail below through specific embodiments in conjunction with the drawings.

[0022] Such as Figures 1 to 5As shown in the figure, this embodiment provides an intake mechanism for an auxiliary heater in a new energy vehicle, which includes a heater housing 1, an inner housing 2, and an air inlet cover 3. The air inlet cover 3 is used for inputting oil and allowing air to enter during the combustion process. One end of the heater housing 1 is an opening, and one end of the inner housing 2 is inserted into the heater housing 1 from the opening position. The air inlet cover 3 covers the other end of the inner housing 2. A cavity is formed inside the inner housing 2, and the cavity is the combustion space. A number of first air inlet holes 31 are provided on the periphery of the air inlet cover 3, and the first air inlet holes 31 extend inward to form air vent grooves 32. The air vent grooves 32 are inclined in the same direction.

[0023] Further, the air vent grooves 32 are arranged equidistantly around the axis of the air inlet cover 3. The equidistant arrangement can make the air form a more regular swirl for full combustion.

The harmful particles, nitrogen oxides, carbon monoxide and other emissions in the exhaust gas cannot be effectively controlled, which is not conducive to realizing the environmental protection problem. Therefore, an intake mechanism for an auxiliary heater in a new energy vehicle is provided. A number of first air inlet holes 31 are provided on the periphery of the air inlet cover 3, and the first air inlet holes 31 extend inward to form air vent grooves 32.
