Problems solved by technology

Although these two dust removal technologies solve the problem of automatic dust removal, the addition of ejector dust removal devices not only reduces the intake air volume of the engine, but also increases the air intake resistance, which affects the normal performance of the engine performance.

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, this kind of automobile automatic dust removal device includes: a housing 5, a piston 4, a motor 1 and a crank connecting rod mechanism 2. The interior of the housing 5 is provided with a temporary storage chamber 51, a dust inlet 52, a cavity 53, a dust storage chamber 54, and a dust discharge outlet 55 from top to bottom in sequence, and the piston 4 and the motor 1 are both arranged in the cavity 53. The output end of the motor is connected with the side wall of the piston 4 via a crank linkage.

[0019] In order to speed up the flow rate of dust downwards, the cross sections of the temporary storage chamber 51 and the dust storage chamber 54 are both wedge-shaped, and the lower bottom of the wedge is gradually tightened to communicate with the dust inlet and the dust outlet respectively. In order to form a better sealing effect, ...

Abstract

The invention relates to an automobile automatic dust discharging device which is installed in a pre-filtering air feeding system of an automobile and aims at achieving automatic dust discharging, prolonging the servicing period of an air filter filtering element and reducing maintenance cost of users under the premise that air feeding resistance and air feeding flow are not increased. The automobile automatic dust discharging device is characterized by comprising a casing, a piston, a motor and a crank-link mechanism. A temporary storage room, a dust feeding port, a cavity, a dust storage room and a dust discharging port are sequentially arranged in the casing from top to bottom. The piston and the motor are arranged in the cavity, the output end of the motor is connected with the piston through the crank-link mechanism. The motor drives the piston to reciprocate vertically through the crank-link mechanism, and the dust feeding port and the dust discharging port are in the closing or opening state with the vertical movement of the piston.

Description

technical field [0001] The invention relates to a dust discharge device, in particular to an automatic dust discharge device used in automobiles. Background technique [0002] During the operation of the vehicle, the air intake system will inhale the dust in the air. If the pre-filtered dust is not discharged in time, the dust will enter the air filter again and block the filter element prematurely, resulting in increased air intake resistance and affecting the normal operation of the engine. In order to ensure the normal operation of the engine, the user must maintain and replace the filter element in time, which not only affects the normal use of the user, but also increases the cost burden of the user. [0003] In order to improve the maintenance cycle of the air filter, people will install a pre-filter device in the dirty air pipe of the intake system or the air filter, but the pre-filtered dust cannot be discharged in time, causing the dust to enter the air filter agai...
