Abstract
Description
Technical Field
[0001] The utility model designs a device for deeply replacing engine oil. Background Art
[0002] Engine oil has four functions: cooling, lubricating, cleaning and sealing, and plays a vital role in ensuring the normal operation of the engine. As the engine works longer, the engine oil is contaminated due to factors such as high-temperature oxidation, wear of mechanical parts, and corrosion of fuel vapor. In addition, during normal use, the engine oil will also be consumed to a certain extent. Therefore, we should regularly check the oil level and its degree of contamination, which is why the oil should be changed regularly. If the oil is lower than the specified value, it will affect the operation of the engine and will cause fatal damage to the engine.
[0003] At present, the traditional process of changing the engine oil is: when changing the engine oil, first remove the drain bolt on the oil pan, drain the old oil at the bottom of the oil pan by gravity, tighten the drain bolt after draining it, open the engine oil filling cap and fill the new engine oil into the engine from the oil filling port. The filling process can be done manually or with an automatic oil filling machine. The shortcomings of this traditional and or currently conventional oil replacement method are: after gravity discharge, there will be old oil and some impurities remaining in the oil passage of the engine lubrication system, which cannot be discharged by gravity. This part of the remaining old oil accounts for about 20% of the total oil volume; therefore, after the engine is replaced with new oil, the old oil remaining in the oil passage of the lubrication system will contaminate the new oil, thereby reducing the quality of the new oil and affecting the life of the engine. Utility Model Content
[0004] The purpose of the invention of the utility model is to provide an engine deep oil replacement device, which can blow out and discharge all the old oil, black sludge, colloid, and oxidation aggregates remaining in the oil channel of the lubrication system, and at the same time perform a deep lubrication maintenance on the entire lubrication system while filling in new oil, and can complete the accurate oil filling in one time, saving labor and time, and the operation is quick and convenient.
[0005] The technical scheme of the utility model is: a kind of engine deep oil replacement equipment, which comprises a shell and a steel cylinder arranged in the shell; an oil filling port with a sealing cover is arranged on the top of the steel cylinder, and the filling port is assembled to expose the top of the shell; an air inlet is arranged on the upper part or top of the steel cylinder, and an external air source device is connected to the air inlet through an air source switch, a pressure regulating valve, a three-way valve, and a filling switch in sequence; the other way of the three-way valve is connected to an old oil purge pipeline; an oil outlet is arranged at the bottom of the steel cylinder, and the oil outlet is connected to a new oil filling pipeline; quick connectors are arranged at the ends of the old oil purge pipeline and the new oil filling pipeline and are equipped with a common matching connector, and the old oil purge pipeline and the new oil filling pipeline can be successively connected with the interface of the oil filter seat on the engine through the matching connector; the steel cylinder is equipped with an oil level observation mechanism.
[0006] Furthermore, the pressure regulating valve of the utility model and the pressure gauge matched with the pressure regulating valve are assembled and arranged on the top panel of the shell.
[0007] Furthermore, the utility model provides a matching connector that is used in conjunction with the quick connectors at the ends of the old oil purge pipeline and the new oil filling pipeline, and its structure is as follows: the matching connector includes a shell that matches the engine oil filter seat, a cover plate is fixed to the front end of the shell, a sealing ring that matches the engine oil filter seat is mounted on the cover plate, a threaded hole that matches the connector on the engine oil filter seat is provided in the center of the cover plate, an oil outlet is provided on the cover plate, and a male or female head of a quick connector is provided at the top of the rear end of the shell in a sealing connection; correspondingly, the female or male head of the quick connector is provided at the ends of the old oil purge pipeline and the new oil filling pipeline.
[0008] Furthermore, the above-mentioned matching connectors of the utility model are manufactured into a set according to the specifications of different automobiles; when in use, the matching connectors of corresponding specifications can be used according to the type of automobile.
[0009] Furthermore, the engine oil level observation mechanism described in the utility model is a transparent communicating tube which is arranged on one side of the cylinder and displays the engine oil level.
[0010] Furthermore, the transparent communicating tube for displaying the oil level on one side of the steel tank of the utility model has the following structure: it includes a transparent communicating tube arranged on the side wall of the outer shell, the transparent communicating tube is connected to the top and bottom of the steel cylinder through a connecting pipe and a joint, and a scale for comparing the liquid level height is provided on the side wall of the outer shell.
[0011] Furthermore, the utility model provides an exhaust valve on the sealing cover of the cylinder filling port, so as to achieve convenient and rapid exhaust after the new engine oil is filled, so as to recover the engine oil in the pipeline and the joint, and at the same time improve the rationality and safety of the exhaust of the filling port.
[0012] Furthermore, the utility model can connect and install a three-way valve for exhaust between the cylinder pressure regulating valve and the gas source switch to replace the exhaust valve on the sealing cover, thereby preventing the problem of unsafe exhaust through the filling port.
[0013] The beneficial effects of the utility model are:
[0014] The utility model can blow out all the old oil, black sludge, colloid and oxidation aggregates remaining in the oil channel of the lubrication system, perform a deep detoxification on the entire lubrication system, avoid the old oil from contaminating the new oil, improve the quality of the new oil, extend the engine life, and extend the mileage. The traditional way of replacing the new oil is difficult to remove the old oil and impurities, and the new oil mixed with the old oil and impurities will significantly reduce the quality of the new oil, bringing adverse consequences.
[0015] Traditional repair shops usually replace engine oil by manual filling, which generally uses a funnel and oil pipe with an oil barrel. Since overfilling the engine with oil will be harmful to the engine, too much new oil cannot be added at one time. It must be added in multiple times, and the amount of filling is determined by the oil dipstick each time. This makes it impossible to ensure accurate filling, and the filling is not in place, which is labor-intensive and wasteful. The equipment of the utility model can complete accurate oil filling in one time through the control of the oil level observation mechanism and the valve, without the need for secondary filling.
[0016] After the filling is completed, the air is released through the exhaust valve on the cylinder cap or the air line. In this way, the new oil in the new oil filling pipe and the front end matching joint will fall back into the cylinder due to gravity, which will not cause waste and can avoid oil leakage and environmental pollution when disassembling the matching joint.
[0017] When the utility model is used to replace the engine oil, the new engine oil will enter the engine lubrication system from the oil filter joint under a certain pressure. Under the action of pressure, the new engine oil will form a certain flushing on the entire lubrication system pipeline and other places, which is equivalent to a deep lubrication maintenance, which can effectively reduce engine wear and extend the service life of the engine. If you insist on using this new oil filling method, the benefits brought to the engine will continue to accumulate and improve significantly.
[0018] This utility model has been praised as a deep oil change tool for engine oil after trial by customers. In use, under the same brand of oil, the same price, and the same service, car owners will be more willing to choose to use this utility model product. Because this magic tool will greatly reduce the mixing of new oil with old oil and impurities that cannot be discharged from the engine oil channel, and can also solve the problem of different mixing of raw materials (base oil and additives) of different oil brands, and improve the oil quality by 30% compared with the traditional oil change method. In short, the use of this utility model is to perform a deep oil change, and its effect is to kill two birds with one stone. The combination of multiple advantages can significantly extend the life of the engine. Repair shops that use this product will have higher market competitiveness and can improve performance.
