Description

Technical Field

[0001] This utility model relates to the field of fuel filter technology, specifically a fuel filter for a refueling machine that can drain fuel. Background Technology

[0002] A drainable fuel filter is a device used in fuel dispensers to drain residual fuel.

[0003] Based on the above, the inventors have discovered that while there are many fuel filter elements on the market, ordinary fuel filter elements tend to adsorb some fuel onto the filter screen on the outer wall of the fuel filter element when filtering impurities from the fuel entering the outer surface of the fuel filter element. Therefore, after long-term use, the fuel filter element needs to be disassembled and cleaned regularly by the staff, which can easily reduce the service life of the fuel filter element and reduce the practicality of the device. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a fuel filter element for fuel dispensers that can drain fuel, in order to achieve a more practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a fuel filter element for a fuel dispenser that can drain fuel, comprising a housing, a filter element body provided on the inner wall of the housing, a top cover provided on the top of the housing, a cleaning mechanism provided on the inner wall of the housing, and an installation mechanism provided on the outer wall of the cleaning mechanism.

[0006] The cleaning mechanism includes:

[0007] The brush plate has an outer wall that slides against the inner wall of the outer shell. The brush plate is set on the outer wall of the filter element body. The inner wall of the outer shell has two sliding grooves. The inner walls of the two sliding grooves are provided with concave plates. The inner walls of the two concave plates are provided with convex plates. One side of the two convex plates is fixed to the outer wall of the brush plate. The inner walls of the two sliding grooves are provided with springs.

[0008] As a preferred embodiment of this utility model, recesses are fixed on both sides of the outer shell, and both recesses are located at the bottom of the top cover.

[0009] As a preferred embodiment of this utility model, the inner walls of both sliding grooves are fixed with connecting rods, the outer walls of both connecting rods slide against the inner wall of the concave plate, and both connecting rods are disposed on the inner wall of the spring.

[0010] As a preferred embodiment of this utility model, the top ends of both springs are fixed to the bottom end of the concave plate, and the bottom ends of both springs are fixed to the inner wall of the groove.

[0011] As a preferred embodiment of this utility model, the installation mechanism includes:

[0012] Two horizontal columns are provided, with the outer walls of both columns fitting into the inner walls of the concave plate, and the outer walls of both columns matching the inner walls of the convex plate.

[0013] As a preferred embodiment of this utility model, the inner walls of the two horizontal columns are provided with inserts, the outer walls of the two inserts are sleeved with the top of the convex plate, the top of the two inserts are fixed with support plates, and the bottom ends of the two support plates are located at the top of the convex plate.

[0014] As a preferred embodiment of this utility model, the bottom ends of the two recesses are provided with square holes, the inner walls of the two square holes are provided with square pillars, and the top ends of the two square pillars are fixed to the bottom end of the top cover.

[0015] The beneficial effects of this utility model are:

[0016] 1. In this solution, when fuel enters the housing through the inner wall of the top cover, the fuel is driven by the power of the oil pump. When the fuel comes into contact with the brush plate, the brush plate squeezes the spring on the outer wall of the connecting rod and contracts. After the fuel has completely passed through, the elasticity of the spring drives the brush plate to move up and down on the inner wall of the housing to empty and remove the fuel remaining on the outer wall of the filter element. This avoids fuel accumulation caused by prolonged use of the device, which reduces the service life of the filter element and eliminates the need for continuous disassembly and maintenance by the staff, thus improving the effectiveness of the device.

[0017] 2. This solution involves installing the brush plate by engaging the inner wall of the convex plate fixed to the outer wall of the brush plate with the inner wall of the concave plate, then fitting the outer wall of the horizontal column with the inner wall of the concave plate, and finally fitting the outer wall of the insert block fixed at the bottom of the support plate with the top of the convex plate until the bottom of the insert block matches the inner wall of the horizontal column. The outer wall of the filter element body is then placed on the inner wall of the outer shell. The outer wall of the top cover slides against the top of the outer shell until the bottom of the top cover contacts the concave blocks fixed on both sides of the outer shell. Simultaneously, the square column fixed at the bottom of the top cover engages with the inner wall of the square hole, thus securing the top cover to the top of the outer shell. This also securely mounts the filter element body to the inner wall of the outer shell, facilitating regular replacement of the brush plate by operators. This ensures better cleaning of the fuel on the filter screen on the outer wall of the filter element body, improving the practicality of the device. Attached Figure Description
