Abstract
Description
Technical Field
[0001] This application relates to the field of fuel filter technology, and in particular to a fuel filter housing structure with a liquid level observation window. Background Technology
[0002] There are three types of fuel filters: diesel filters, gasoline filters, and natural gas filters. The function of a fuel filter is to prevent particulate matter, water, and other impurities from entering the fuel, ensuring that the precision components of the fuel system are protected from wear and other damage.
[0003] While existing fuel filters are generally good for daily use, they are often sealed off during use. This makes it difficult to observe the internal fuel flow status through the viewing window. Furthermore, after prolonged use, the dust adhering to the viewing window surface is not easily removed, reducing the clarity of subsequent observation of the fuel flow status by the operator. Utility Model Content
[0004] This application provides a fuel filter housing structure with a liquid level observation window to solve the problems of poor observation of the fuel delivery status inside the fuel filter through the observation window, and poor simultaneous adsorption and scraping of dust adsorbed on the surface of the observation window during long-term use.
[0005] This application provides a fuel filter housing structure with a liquid level observation window, including a filter body, an oil inlet pipe at one end of the filter body, an oil outlet pipe at the other end of the filter body, an observation window fixedly connected to the outer wall of the filter body, a protective cover slidably connected to the outer wall of the observation window, a slider fixedly connected to the inner side wall of the protective cover and slidably connected to the outer wall of the observation window, an observation port plate rotatably connected to the outer wall of the protective cover, a limit rod slidably connected to the outer wall of the protective cover, a connecting rod fixedly connected to one end of the limit rod, and a scraper located on one side of the observation window fixedly connected to the outer wall of the connecting rod.
[0006] Preferably, a groove is provided at the connection between the outer wall of the observation window and the slider.
[0007] Preferably, a connecting block is fixedly connected to the outer wall of the observation window, and a first nut is provided on the outer wall of the connecting block. A first bolt located on one side of the protective cover is threadedly connected to the inner wall of the first nut.
[0008] Preferably, the scraper is made entirely of hard silicone.
[0009] Preferably, the outer wall of the protective cover is provided with a second nut, and the inner wall of the second nut is threaded with a second bolt that is rotatably connected to the outer wall of the connecting rod.
[0010] Preferably, there are two sets of limiting rods, and the positions of the two sets of limiting rods are symmetrical about the central axis of the connecting rod.
[0011] Preferably, the end of the contact area between the second bolt and the protective cover is provided with anti-slip texture. Beneficial effects
[0012] While existing fuel filters are generally good for daily use, they are often sealed off during operation. This makes it difficult to observe the internal fuel flow status through the viewing window. Furthermore, after prolonged use, the dust adhering to the viewing window surface is not easily removed, reducing the clarity of subsequent observation of the fuel flow status by the operator.
[0013] When it is necessary to observe the oil delivery status in the fuel filter through the observation window, in order to improve the effect of simultaneously wiping and cleaning the dust adsorbed on the surface of the observation window, the protective cover can be pulled up when the observation window is needed. This will cause the slider to slide along the inner wall of the slide groove, and the second bolt will be rotated. Through the limiting action of the second nut, the connecting rod fixedly connected to the limiting rod will move in an extension and retraction motion, so that the scraper is in contact with the surface of the observation window. With the continuous rise of the protective cover, the scraper can simultaneously scrape and clean the dust on the surface of the observation window, achieving a clear observation of the oil delivery status.

[0028] This utility model provides, for example Figure 1-4 The fuel filter housing structure with a liquid level observation window shown includes a filter body 1, an oil inlet pipe 2 at one end of the filter body 1, an oil outlet pipe 3 at the other end of the filter body 1, an observation window 4 fixedly connected to the outer wall of the filter body 1, a protective cover 5 slidably connected to the outer wall of the observation window 4, a slider 6 fixedly connected to the inner side wall of the protective cover 5 and slidably connected to the outer wall of the observation window 4, an observation port plate 8 rotatably connected to the outer wall of the protective cover 5, a limit rod 15 slidably connected to the outer wall of the protective cover 5, a connecting rod 14 fixedly connected to one end of the limit rod 15, and a scraper 16 located on one side of the observation window 4 fixedly connected to the outer wall of the connecting rod 14.
[0029] Among them, a groove 7 is provided at the connection between the outer wall of the observation window 4 and the slider 6.
[0030] The setting of the slide groove 7 is conducive to achieving the effect of driving the protective cover 5 to slide and limit.
[0031] Among them, the outer wall of the observation window 4 is fixedly connected to a connecting block 9, the outer wall of the connecting block 9 is provided with a first nut 10, and the inner wall of the first nut 10 is threadedly connected to a first bolt 11 located on one side of the protective cover 5.
[0032] The setting of the first bolt 11 is beneficial to achieve the effect of keeping the protective cover 5 in an upward state after it rises.
[0033] The scraper 16 is made of hard silicone.
[0034] The scraper 16 is made of hard silicone, which makes it easy to remove dust adsorbed on the surface of the observation window.
[0035] The outer wall of the protective cover 5 is provided with a second nut 12, and the inner wall of the second nut 12 is threaded with a second bolt 13 that is rotatably connected to the outer wall of the connecting rod 14.
[0036] The second bolt 13 facilitates the convenient telescopic movement of the connecting rod 14.
[0037] The limiting rod 15 is provided in two sets, and the positions of the two sets of limiting rods 15 are symmetrical about the central axis of the connecting rod 14.
[0038] This is beneficial because by setting two sets of limit rods 15 with their positions symmetrical about the central axis of the connecting rod 14, the sliding stability of the connecting rod 14 can be achieved.
[0039] The second bolt 13 has anti-slip texture at the end of its contact point with the protective cover 5.
[0040] The anti-slip texture is provided at the end of the contact part between the second bolt 13 and the protective cover 5, which helps to improve the stability of the protective cover 5 in the open and closed state.
[0041] Working principle: When using this fuel filter housing structure with a liquid level observation window, to improve the effect of simultaneously wiping and cleaning the dust adsorbed on the surface of the observation window, the protective cover 5 can be pulled upwards when the observation window is needed. This causes the slider 6 to slide along the inner wall of the slide groove 7, and the second bolt 13 is rotated. Through the limiting action of the second nut 12, the connecting rod 14, which is fixedly connected to the limiting rod 15, is driven to extend and retract, so that the scraper 16 is in contact with the surface of the observation window. Under the continuous rising action of the protective cover 5, the scraper 16 simultaneously scrapes and cleans the dust on the surface of the observation window, achieving a clear observation of the oil delivery status.
