Description

Technical Field

[0002] An engine is a machine that can convert other forms of energy into mechanical energy. It is applicable to power generating devices and can also refer to the entire machine including the power device. When running, the engine's fuel mixes with air and burns to generate heat energy. The gas expands due to the heat and is converted into mechanical energy through mechanical devices to do external work.

[0003] In order to prevent foreign particles in the air from entering the engine and causing wear on the cylinder liner, piston and piston ring of the engine combustion chamber, an air filter is installed at the intake end. Existing air filters are mainly filter mesh or filter sponge structures, which are prone to dust adhesion and blockage after long-term use, affecting air intake; in addition, the filter mesh will inevitably allow some fine particles to pass through, resulting in poor filtering effect.

[0007] With the above structure, air is sent into the water storage chamber by the air pump through the air inlet pipe. After the air contacts the liquid in the water storage chamber, the particles in the air will be trapped by the liquid, and the clean air will overflow from the liquid surface and gather in the area between the liquid and the waterproof breathable membrane assembly, and finally pass through the waterproof breathable membrane assembly and flow out from the air supply end of the first air inlet pipe. The structure is simple and reasonable. After the air passes through the liquid to filter out impurities, the waterproof breathable membrane assembly removes moisture from the air, thereby ensuring clean and dry air delivery. Moreover, after the liquid is filtered, it is not easy to be blocked and can work efficiently for a long time.

[0008] Furthermore, an air pump is also provided on the first air inlet pipe, and the air pump is located on the side of the waterproof breathable membrane assembly facing the air supply end.

[0009] In this way, the pressure difference between the inside and outside of the waterproof breathable membrane assembly can be increased by the vacuum pump, thereby increasing the air permeability of the waterproof breathable membrane assembly.

[0010] Furthermore, the waterproof breathable membrane assembly includes a ring-shaped support seat and a waterproof breathable membrane arranged on the support seat, and the support seat is detachably installed in the first air inlet pipe.

[0011] Furthermore, the first air inlet pipe includes an air supply pipe section located at the top and a water storage pipe section located at the bottom, and the support seat is detachably mounted on the lower end of the air supply pipe section; the water storage pipe section is detachably connected to the bottom of the air supply pipe section.

[0012] Furthermore, the support seat has a columnar support tube, which includes a support rod arranged along the axial direction, and a plurality of support rods are evenly distributed along the circumference of the support seat, and support ribs extending along the circumference of the support seat are connected between the support rods; the waterproof and breathable membrane is covered on the support tube; the outer diameter of the support tube is smaller than the inner diameter of the air supply pipe section, and extends into the air supply pipe section.

[0013] In this way, the effective air permeability area of ​​the waterproof breathable membrane can be increased, thereby increasing the air permeability.

[0014] Furthermore, the second air inlet pipe includes an air inlet pipe section located at the upper end and an air outlet pipe section located at the lower end; a sealing plate is provided at one end of the water storage pipe section away from the waterproof breathable membrane assembly; the air outlet pipe section is located in the water storage pipe section, and one end is connected to the sealing plate, and the sealing plate has an air inlet hole that is arranged to pass through the air outlet pipe section; the air inlet hole is detachably connected to the lower end of the air inlet pipe section.

[0015] In this way, the water storage pipe section and the air outlet pipe section are connected into an integral structure through the sealing plate, thereby facilitating disassembly and maintenance.

[0016] Furthermore, a water inlet hole and a drainage hole are provided on the side wall of the water storage pipe section, the water inlet hole is located near the upper end of the water storage pipe section, and the drainage hole is located at the lowest point of the water storage pipe section; the water inlet hole and the drainage hole are detachably equipped with sealing components.

[0017] Furthermore, an overflow hole is provided on the side wall of the water storage pipe section, and the overflow hole is located near the upper end of the water storage pipe section and is lower than the water inlet hole.

[0018] Furthermore, the water storage pipe section is U-shaped as a whole, and the air outlet end of the air outlet pipe section is located on the side of the water storage pipe section connected to the waterproof breathable membrane assembly.
