[0069] In one example, in conjunction with Figure 6 and attached Figure 7 A second adjusting member is provided in the liquid inlet pipe 41, and the second adjusting member can realize the on-off control of the cleaning liquid. The second adjusting member includes a second elastic member 415, a blocking member 416, a connecting seat 417 and a connecting column 418. The second elastic member 415 is located on the side of the connecting seat 417 close to the liquid inlet of the liquid inlet pipe 41 and is connected to the connecting seat 417. The connecting column 418 is penetrated by the connecting seat 417. The side of the connecting column 418 close to the connecting seat 417 is connected to the blocking member 416, so that the blocking member 416 is located on the side of the connecting seat 417 close to the liquid inlet and contacts with the connecting seat 417. The end of the connecting column 418 away from the blocking member 416 is connected to the trigger 50, and the blocking member 416 can be separated from the connecting seat 417 by operating the trigger 50.

[0070] When cleaning liquid enters the liquid inlet pipe 41 , the blocking member 416 is separated from the connecting seat 417 by the trigger 50 . At this time, the cleaning liquid can enter the liquid discharge pipe 42 and the functional pipe 43 through the gap between the connecting seat 417 and the blocking member 416 .

[0071] Combined with Figure 6 and attached Figure 7 The trigger 50 includes a base 51 and a fixed shaft 52 . The base 51 includes a functional cavity 511 . The functional part 10 is arranged in the functional cavity 511 , and the functional part 10 is connected to the functional pipe 43 . The base 51 is connected to the functional pipe 43 through the fixed shaft 52 , and the base 51 is connected to the connecting column 418 .

[0072] More specifically, a mounting plate 431 is protruding from the functional pipe 43, an axial hole is opened on the mounting plate 431, a matching hole 512 is opened on the base 51, the matching hole 512 is matched with the axial hole, and the fixed shaft 52 is passed through the matching hole 512 and the axial hole to realize the connection between the base 51 and the functional pipe 43.

[0073] In one example, as shown in the attached Figure 6 As shown, the control unit 40 also includes an extension pipe 44, which is connected to the liquid inlet pipe 41, the liquid discharge pipe 42 and the functional pipe 43. The extension pipe 44 includes a through hole that cooperates with the connecting column 418. The end of the connecting column 418 away from the connecting seat 417 passes through the through hole and is connected to the base 51. A third elastic member 53 is provided between the extension pipe 44 and the base 51. The third elastic member 53 is sleeved on the connecting column 418. The third elastic member 53 is used to apply a thrust to the connecting column 418 so that the connecting column 418 and the connecting seat 417 connected thereto can be reset.

[0074] In one example, a gasket 531 is disposed between the third elastic member 53 and the base 51 .

[0075] In one example, a third sealing member 419 is provided at the through hole between the connecting column 418 and the extending connecting pipe 44 , and the third sealing member 419 is used to prevent the cleaning liquid from leaking from the through hole.

[0076] In one example, as shown in the attached Figure 5 As shown, the trigger 50 also includes a lock buckle 54, which cooperates with the base 51 to limit the base 51. A second connecting hole 323 is provided on the side where the first shell 31 and the second shell 32 are close to each other. A second fixing column 541 that cooperates with the second connecting hole 323 is protruded on the lock buckle 54. When the trigger 50 is installed between the first shell 31 and the second shell 32, the second fixing column 541 is accommodated in the second connecting hole 323, so that the lock buckle 54 can be quickly positioned and connected.

[0077] As attached Figure 7As shown in the direction of the arrow in the figure, after the cleaning liquid enters the liquid inlet pipe 41, it will flow toward the liquid discharge pipe 42 and the functional pipe 43 in the first direction, and the cleaning liquid can contact the movable part 11. The user adjusts the hydraulic pressure of the cleaning liquid by adjusting the pressure regulating part at the liquid discharge pipe 421. When the force of the hydraulic pressure acting on the movable part 11 is greater than the reset force of the reset part 12, the movable part 11 will move along the first direction, and its position change relative to the display part 20 can facilitate the user to observe the hydraulic pressure of the cleaning liquid at this time.

[0078] In another example, as shown in the attached Figure 4 As shown, the arrow indicates the flow direction of the cleaning liquid. The utility model also proposes a high-pressure cleaning spray gun, including a functional part 10 and a drainage pipe 421. The functional part 10 is connected to the drainage pipe 421. A liquid hole 4211 is opened on the drainage pipe 421. The liquid hole 4211 can be connected to the adapter 14. The cleaning liquid in the drainage pipe 421 can flow from the liquid hole 4211 through the connecting pipe 141 to contact the movable part 11 to display the hydraulic pressure of the cleaning liquid. The position of the adapter 14 can be adjusted according to actual needs, without being limited by the size and specifications of the first shell 31 and the second shell 32, and has strong flexibility.

[0079] Optionally, a sealing gasket 142 is provided between the adapter 14 and the drainage pipe 421 to prevent the cleaning liquid from leaking from the connection between the adapter 14 and the drainage pipe 421 .

[0080] The high-pressure cleaning spray gun proposed by the utility model can help users know the hydraulic pressure of the cleaning fluid, so that users can freely adjust it according to actual cleaning needs, and it is convenient for users to judge the cleaning fluid hydraulic data required for the cleaning situation, enriching the function of the high-pressure cleaning spray gun and improving the user's experience.
