[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Please see Figure 1-6 As shown, A waterproof air-guiding structure for a high-pressure washer, comprising: The outer shell 1 is composed of a front shell 1.1 and a rear shell 1.2 that fit together and are fixed together by snaps or screws, and forms an installation cavity 1.3 inside. The partition rib 2 is located on the opposite surfaces of the front shell 1.1 and the rear cover 1.2, and after assembly, it defines the upper and lower partitioned mounting cavity 1.3. The lower mounting cavity 1.3 can accommodate a vertically arranged motor pump assembly 3, and an air outlet is provided on the outer shell 1 at the position corresponding to the lower mounting cavity 1.3. An air intake channel 4 is formed between the upper mounting cavity 1.3 and the outer shell 1. The air intake duct 4 includes an air inlet 4.1 and an air outlet 4.2. An air inlet 4.1 is located on the side wall of the outer casing 1 to receive external air, and an air outlet 4.2 is located on the partition rib 2 and is connected to the air inlet of the motor.

[0021] In this application, by setting partition ribs 2, after the front shell 1.1 and the rear cover 1.2 are connected front and rear, the partition ribs 2 combine to separate the mounting cavity 1.3 to form an upper and lower separated structure, wherein the lower mounting cavity 1.3 can be used to install the vertically arranged motor pump assembly 3. An air inlet channel 4 is formed between the upper mounting cavity 1.3 and the outer shell 1. The air inlet 4.1 of the air inlet channel 4 is opened on the side wall of the outer shell 1 to receive external air. The air outlet 4.2 of the air inlet channel 4 is located on the partition rib and is connected to the air inlet end of the motor.

[0022] It meets the design requirements to prevent water from entering the motor part, replaces the traditional front and rear air guide covers, reduces the number of parts, simplifies the assembly process, and reduces production costs.

[0023] Please see Figure 2 , Figure 4 , Figure 5 , Figure 6 As shown, the partition bar 2 includes partition bar a2.1 and partition bar b2.2; The outer ends of the partition ribs 2 are connected to the outer shell 1, and the inner ends extend upward and inward at an incline to form a gradually converging "eight" shaped structure. The air inlet 4.1 is located on the side wall of the outer casing 1, and is positioned immediately adjacent to the outer end of the partition rib 2. Air outlet 4.2 is located between the inner ends of partition rib 2.

[0024] After the above improvements, the air intake channel 4 forms a continuous upward and inward sloping flow channel from the air inlet 4.1 to the air outlet 4.2, and the setting height of the air inlet 4.1 is lower than that of the air outlet 4.2.

[0025] When water enters the air intake channel 4 with the airflow, due to gravity, the water tends to flow back along the surface of the inclined partition rib 2 to the air inlet 4.1 and be discharged outwards, while the lighter air continues to rise through the air outlet 4.2, thus achieving self-draining waterproofing without the need for additional valves.

[0026] In some embodiments, a first sponge 5 is provided between the mating surfaces of the partition ribs 2, which can effectively prevent liquid leakage and also serve as a buffer to reduce noise and vibration.

[0027] Please see Figure 4 , 5 As shown, a wind guide 6 is provided on the front shell 1.1. The position of the wind guide 6 corresponds to the position on the upper side of the air outlet 4.2. The wind guide 6 has downwardly extending protrusions 6.1 at both ends. The protrusion 6.1 covers the inner end of the partition rib 2 to form an inverted air supply section with a "U" shaped structure in conjunction with the partition rib 2.

[0028] The "U"-shaped air supply section acts as a noise-absorbing expansion chamber for high-speed airflow, reducing noise, rectifying the airflow, reducing eddies, and improving gas throughput efficiency.

[0029] In some embodiments, a second sponge 7 is provided in the air inlet channel 4. The second sponge 7 is embedded in the air inlet end of the air supply section to filter the passing gas and further reduce noise.

[0030] In some embodiments, the front shell 1.1 and the partition rib a2.1 are integrally injection molded structures, and the rear cover 1.2 and the partition rib b2.2 are integrally injection molded structures. After the above improvements, the structure has the characteristics of simple processing and manufacturing and low cost.

[0031] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
