DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 4 As shown, this utility model provides an air knife assembly, including: a blade body 1, an air inlet seat 2, and an air outlet seat 3. The blade body 1 is generally strip-shaped, and the air inlet seat 2 is set as a disc-shaped structure. One end of the blade body 1 is fixed to the side of the air inlet seat 2, and the other end of the blade body 1 is provided with a mounting seat 11. The air outlet seat 3 is connected to the mounting seat 11. The air inlet seat 2 is provided with an air inlet 21, and the air inlet 21 is connected to an air pump through a pipe. The blade body 1 is hollow inside, and the air inlet seat 2 and the air outlet seat 3 are interconnected through the interior of the blade body 1. The air outlet seat 3 is provided with an air outlet nozzle 31. The mounting seat 11 is provided with mounting plates 12 side by side, and the mounting plates 12 are arranged side by side on both sides of the air outlet seat 3. The mounting plates 12 are provided with slots 13, and the mounting plates 12 and the air outlet seat 3 are engaged with each other.

[0019] The air inlet 21 has an overall annular structure, and its outer side is threaded to connect to the air pump's pipe. An annular bracket 22 is located on the inner side of the air inlet 21, and a filter 4 is installed inside. The filter 4 is engaged with the bracket 22 via a second bracket 41. The filter 4 is stably secured to the inner side of the air inlet 21 by the second bracket 41, allowing for easy removal and replacement, and effectively filtering the incoming air to prevent debris from entering and affecting the overall airflow and the vehicle's air delivery performance.

[0020] The blade body 1 is perpendicularly connected to the side of the air inlet seat 2 at one end, and bent at the other end. The air outlet 31 is designed as a frustum-shaped structure with a hollow interior. An annular sealing gasket 32 ​​is provided on the side of the air outlet seat 3 facing the mounting base 11, and the sealing gasket 32 ​​is inserted into the air outlet on the mounting base 11. The frustum-shaped air outlet 31, during actual air output, further compresses the gas as it is ejected, thereby increasing the air output speed and improving the blowing effect.

[0021] The air outlet base 3 has a square structure, and symmetrical levers 5 are embedded inside it. The levers 5 are generally U-shaped, with both ends extending from the slots 33 at both ends of the air outlet base 3. Each lever 5 has a locking pin 51, and the side of the air outlet base 3 has a pin hole 34. The locking pin 51 passes through the pin hole 34 and engages with the slot 13 on the inner side of the mounting plate 12. The two ends of the U-shaped levers 5 are located outside the air outlet base 3. Users can move the levers 5 to adjust the position of the locking pins 51 and change their relationship with the slots 13, thus assembling and disassembling the air outlet base 3.

[0022] The lever 5 has a spring rod 53 on the side facing away from the locking pin 51. The spring rod 53 is inserted into the sleeve 54 by a spring, and the sleeve 54 is fixed inside the air outlet seat 3. The spring pushes the spring rod 53 to always be locked in the slot 13 without external force, which helps to maintain the stability of the air outlet seat 3.

[0023] The lever 5 has pressure blocks 52 at both ends, which are made of rubber and located outside the lever groove 33. The pressure blocks 52 are easy for the user to access and press to move the lever 5.

[0024] A car wash machine that uses the aforementioned air knife assembly.
