Description

Technical Field

[0001] The invention relates to the field of automobile air drying cylinders, in particular to an automobile air drying cylinder with a lubricating liquid adder. Background Art

[0002] When the air compressor in the automobile brake system supplies air, the compressed air will carry moisture into the vehicle's brake air path and brake components, causing corrosion of metal components and failure of lubrication. In addition, when the temperature is low, the brake components will be frozen, affecting the braking effect and causing driving hazards. The dryer assembly uses the molecular sieve in the drying tank to remove moisture from the compressed air; the drying tank assembly is installed on the automobile dryer body to form the automobile dryer assembly. The moist compressed air enters the drying tank assembly, absorbs moisture through the molecular sieve in the drying tank, and dries the compressed air.

[0003] On February 5, 2007, the State Intellectual Property Office of China announced an invention patent called Automobile Brake Air Dryer, with the announcement number CN2246605. According to lines 17 to 21 on page 4 of the specification and the accompanying drawings, it can be seen that when the invention is in working state, the compressed air of the air compressor enters the pre-drainage chamber through the air port, and the condensed water generated by the compressed air flows into the water containing chamber. The compressed air passes through the air holes on the cylinder disc, passes through the filter screen to the upper end of the drying cylinder, and then enters the molecular sieve for drying. The invention is a common drying tank assembly structure. Moisture, oil and impurities in the air are adsorbed by the molecular sieve and other filters in the drying cylinder, and then the dry air is discharged into the air storage cylinder for storage. When a component needs air, the air storage cylinder supplies air to that part. However, the existing automobile air drying cylinder does not have the function of lubricating and maintaining other components. If the air-using components are not maintained for a long time, the air-using components will fail prematurely. However, other existing air-using components have not been lubricated and maintained since they were installed in the automobile air pipeline until they fail. It is necessary to make improvements to this. Summary of the invention

[0004] The technical problem to be solved by the present invention is to address the deficiencies of the above-mentioned prior art.

[0005] Automotive air dryer cartridges with lubricant dispenser available.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: an automobile air dryer with a lubricating liquid charger, comprising a dryer shell with an opening at one end and a cartridge disc installed at the open end of the dryer shell, a molecular sieve is arranged in the dryer shell, the molecular sieve is installed in the dryer shell through a horn cover, the dryer shell and one end of the horn cover are connected through the cartridge disc, a spring is arranged between the dryer shell and the end of the horn cover away from the cartridge disc, and the characteristic is that a lubricating liquid charger is installed inside the molecular sieve.

[0007] By adopting the above technical scheme, the present invention installs a lubricating liquid adder inside the molecular sieve. When the air dried at the upper end of the molecular sieve passes through the lubricating liquid adder, a certain amount of lubricating oil is taken out from the lubricating liquid adder, so that the filtered air carries the lubricating oil into the air storage cylinder for storage. When other air-using components need to use air, the dry air entering the component carries the lubricating oil, which not only supplies air to the component, but also maintains and lubricates the component due to the presence of the lubricating oil, thereby extending the service life of the component.

[0008] The above-mentioned automobile air dryer cylinder with a lubricating liquid charger can be further configured as follows: the lubricating liquid charger includes a liquid charger shell, lubricating oil is arranged in the liquid charger shell, the liquid charger shell is opened at one end away from the cylinder disk, a first piston is installed in the opening, a limiting structure is provided between the first piston and the liquid charger shell, an oil outlet channel is provided at one end of the liquid charger shell facing the cylinder disk, an oil outlet hole is provided on one side of the oil outlet channel, and an oil outlet amount control structure is provided in the oil outlet channel.

[0009] By adopting the above technical solution, the working principle of the lubricating liquid adder is that when air enters the molecular sieve, the pressure in the molecular sieve increases, and the first piston moves downward under pressure. When the maximum stroke is reached, the first piston stops moving downward under the action of the limiting structure, and the liquid in the lubricating liquid adder is squeezed by the first piston and flows out of the oil outlet hole from the oil outlet channel. By setting an oil output control structure, the control of the single oil output can be effectively improved.

[0010] The above-mentioned automobile air dryer cylinder with lubrication liquid charger can be further configured as follows: the limiting structure includes a first step arranged opposite to one end of the liquid charger housing, the first piston is provided with a first limiting block at a position corresponding to the first step, a first return spring is arranged between the first step and the first limiting block, and one end of the first return spring is abutted against the first step and the other end is abutted against the first limiting block.

[0011] By adopting the above technical solution, when the pressure in the molecular sieve increases, the first piston compresses the first return spring. When the pressure decreases, the first piston returns to its original position under the force of the first return spring. By setting the first step, the first limit block and the first return spring, the movement stroke of the first piston is limited.

[0012] The above-mentioned automobile air dryer with lubrication liquid charger can be further configured as follows: the oil output control structure includes a second piston arranged in the oil outlet channel, the second piston is provided with a connecting hole whose one end is connected to the inside of the liquid charger housing and the other end is connected to the oil outlet hole, and a second return spring is provided in the oil outlet channel, one end of the second return spring is against the bottom of the oil outlet channel and the other end is against the second piston.

[0013] By adopting the above technical solution, when the liquid in the lubricating liquid adder squeezes the second piston, the second piston compresses the second return spring. When the second piston moves along the oil outlet channel to the connecting hole and the oil outlet hole, the connecting hole will discharge the lubricating oil outward. When the pressure in the lubricating liquid adder decreases, the second return spring needs to be reset, squeezing the second piston upward, causing the oil outlet hole and the connecting hole to be disconnected, thereby controlling the oil output.

[0014] The above-mentioned automobile air drying cylinder with lubricating liquid adder can be further configured as follows: the connecting hole is L-shaped.

[0015] By adopting the above technical solution, by setting the connecting hole in an L shape and setting the oil outlet hole on the side of the oil outlet channel, it is prevented that the lubricating oil leaks out when the second return spring fails.

[0016] The beneficial effects of the present invention are: while delivering dry air to various gas-using equipment, the equipment can also be maintained, thereby extending the service life of the various gas-using equipment.
