Therefore, it should not be construed as a limitation on the scope of protection of this utility model. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0037] Please see Figures 1-9As shown, this utility model discloses a spray bar cleaning nozzle for spraying cleaning agent onto the surface of a spray bar 2. The nozzle includes a nozzle body 1, which comprises a main body 11 and multiple spray sections 12. The main body 11 has a liquid inlet channel 111. The multiple spray sections 12 are distributed on different sides of the spray bar 2, and each spray section 12 has a nozzle 121 on its side facing the spray bar 2. The nozzle 121 is connected to the liquid inlet channel 111, thereby allowing the cleaning agent sprayed by this utility model to fully cover the entire spray bar 2, achieving all-around cleaning and improving the cleaning effect.
[0038] Preferably, there are two spray sections 12, which are distributed on both sides of the spray bar 2 laterally. The main body 11 is located on the upper side of the spray bar 2 and is integrally formed or fixedly connected to the two spray sections 12, but it is not limited thereto. In other embodiments, there may be three or more spray sections, and the number of spray sections, the position of the spray sections, and the position of the main body can be specifically set according to different needs.
[0039] Each spray nozzle 12 is provided with a mixing chamber 122 and an air intake 123. The nozzle 121 and the air intake 123 are respectively connected to the mixing chamber 122. An acceleration hole 13 is provided between the mixing chamber 122 and the liquid inlet channel 111. The liquid entering the liquid inlet channel 111 is accelerated into the mixing chamber 122 through the acceleration hole 13, causing the mixing chamber 122 to generate negative pressure and draw in air through the air intake 123. The air and liquid mix to produce foam or bubble water, which constitutes the cleaning agent. Therefore, this invention can foam by self-aspiration, thus eliminating the need for an air pump. While ensuring efficient foaming, it optimizes cost, space, and performance.
[0040] like Figure 3 As shown, the mixing chamber 122 has a flow channel structure, and its length direction is perpendicular to the length direction of the spray bar 2. The two ends along the length direction of the mixing chamber 122 are a first end and a second end, respectively. The first end has an acceleration hole 13, and the second end is closed. Each spray section 12 has one nozzle 121, and the intake port 123 is closer to the acceleration hole 13 than the nozzle 121. With this arrangement, a portion of the foam or sparkling water in the mixing chamber 122 is directly sprayed out from the nozzle 121, while the remaining portion flows to the closed end and then flows back to the nozzle 121 to collide with new foam or sparkling water. This causes the foam or sparkling water to be sprayed out from the nozzle 121 at various angles, ultimately creating a reciprocating oscillation effect along the length direction (i.e., the up-down direction) of the mixing chamber 122. In other embodiments, multiple nozzles are provided, distributed along the length direction of the mixing chamber.
[0041] like Figure 2As shown, the nozzles 121 and air intakes 123 of each spray section 12 are staggered along the length of the mixing chamber 122. The wall containing the nozzle 121 is an inclined wall, which sprays the cleaning agent at an angle toward the extension direction of the spray bar 2. The wall containing the air intake 123 faces the spray bar 2. The nozzles 121 of the two spray sections 12 are distributed along the transverse axis of the spray bar.
[0042] like Figure 3 As shown, the nozzles 121 of the two spray sections 12 are distributed along the horizontal axis of the spray bar 2, so that the cleaning agent sprayed from the nozzles 121 can fully cover the entire spray bar 2, avoiding the problem of cleaning dead corners. The liquid inlet channel 111 extends along the left and right direction of the spray bar 2, and one end of the liquid inlet channel 111 is closed, while the other end is provided with a liquid inlet 112.
[0043] During installation, such as Figure 6 , Figure 8 As shown, two spray sections 12 are located on the left and right sides of the spray bar 2, and the main body 11 spans across the top of the spray bar 2. The inclined wall where the nozzle 121 is located is roughly the front half of the side wall facing the spray bar 2, so that the nozzle 121 emits bubbles at a preset tilt angle α relative to the top surface of the spray bar 2. The wall where the air intake 123 is located is roughly the rear half of the side wall facing the spray bar 2.
[0044] This utility model discloses a spray bar cleaning nozzle. When cleaning the spray bar 2, a foaming solution / water is introduced into the liquid inlet channel 111 of the main body 11. The foaming solution / water is accelerated through two acceleration holes 13 and then enters the mixing chamber 122 of the two spray sections 12 at high speed. This creates a negative pressure in the mixing chamber 122 and draws in air through the air intake port 123. The air mixes with the foaming solution or water to produce foam or bubble water. The foam or bubble water is sprayed out from the nozzle 121 and cleans the surface of the spray bar 2. As described above, the two spray sections 12 are located on the left and right sides of the spray bar 2, respectively. The foam or bubble water sprayed from the nozzle 121 swings up and down, thus fully covering the surface of the spray bar 2 and cleaning it from all directions, improving the cleaning effect.
[0045] Please see Figures 1-9 As shown, a spray bar assembly of this utility model includes a spray bar 2 and a spray bar cleaning nozzle as described above. Multiple spray sections 12 are distributed on different sides of the spray bar. Specifically, the spray bar 2 is cylindrical, but not limited to this; a cylindrical shape provides better cleaning results.
[0046] This utility model also includes a fixing base 3, on which the spray bar 2 is slidably disposed along its length direction, and the spray bar cleaning nozzle is mounted on the fixing base 3. Two spray sections 12 are provided, distributed on both sides of the spray bar 2 laterally, and the main body 11 is located on the upper side of the spray bar 2. The fixing base 3 is provided with a receiving groove 31 adapted to the nozzle body 1, such as... Figure 9As shown, the nozzle body 1 is inserted into the receiving groove 31 from top to bottom, and the fixing seat 3 is provided with an elastic buckle 32 corresponding to the main body 11. The elastic buckle 32 locks the main body 11. The two spraying parts 12 are respectively provided with limiting ribs 124, which are fitted outside the receiving groove 31.

[0049] This invention also includes a foam liquid module 4, a switching valve, and a three-way pipe 6. The inlet of the switching valve is connected to the outlet of the foam liquid module 4. The three-way pipe 6 has a first port, a second port, and a third port that are interconnected. The first port is connected to the outlet of the switching valve, the second port is connected to the inlet of the spray bar 2, and the third port is connected to the inlet channel 111 of the nozzle body 1. This invention also includes a foam shield foaming head 7. Specifically, the switching valve is a first solenoid valve 5.
