When the equipment is in use, the user presses the pressure rod, and then the pressure rod moves and drives the connecting plate to move. When the connecting plate moves, the spring is displaced and deformed to generate elastic force. Then, when the connecting plate moves, the card block is driven to move and detach from the inside of the first connecting block. Then the spray head loses its restraint, and the spray head is pulled out of the inside of the connecting head for replacement. By setting a replacement device, the spray head is effectively replaced, which plays a role in quickly replacing the spray head, reducing the need for different spray heads for spraying when the equipment is in use. Generally, the spray head is firmly installed with bolts, and the installation and removal of the bolts require tools to operate.

[0023] The specific settings and functions of the replacement device 5 and the protection device 6 are described in detail below.

[0024] In this embodiment: the replacement device 5 is arranged on the connecting head 4, and the replacement device 5 includes a nozzle 51 and a first connecting block 52. The nozzle 51 is arranged at one end of the connecting head 4, the first connecting block 52 is fixedly connected to the side of the connecting head 4, and the second connecting block 53 is fixedly connected to the side of the nozzle 51.

[0025] Specifically, the clamping block 55 is clamped with the inner wall of the first connecting block 52 , and the inner wall of the second connecting block 53 is fixedly connected with the sliding rod 57 .

[0026] In this embodiment: by setting the sliding rod 57, the connecting plate 54 can be positioned, which reduces the risk that the connecting plate 54 will shake and detach from the second connecting block 53 when the device is in use, making it difficult for the connecting plate 54 to connect the first connecting block 52 to the second connecting block 53.

[0027] Specifically, the connection plate 54 is slidably connected to the surface of the sliding rod 57 , and a pressure rod 56 is fixedly connected to the surface of the connection plate 54 . The pressure rod 56 is provided to facilitate the movement of the connection plate 54 .

[0028] Specifically, a spring 58 is sleeved and connected to the surface of the slide rod 57 , and two ends of the spring 58 are fixedly connected to the surface of the connecting plate 54 and the inside of the second connecting block 53 respectively. The spring 58 is provided to facilitate applying a restoring elastic force to the connecting plate 54 .

[0029] In this embodiment: a protective device 6 is provided on the surface of the nozzle 51, and the protective device 6 includes a protective cover 61 and an elastic rod 63. The protective cover 61 is sleeved and connected to the surface of the nozzle 51, and the elastic rod 63 is fixedly connected to the surface of the protective cover 61. A groove 62 is provided on the surface of the nozzle 51, and a card slot 64 is provided on the inner wall of the groove 62.

[0030] In this embodiment, the protective cover 61 is provided to protect the nozzle 51, thereby reducing the possibility of foreign matter entering the nozzle 51 and causing blockage when the device is in use.

[0032] Specifically, the locking ball 65 is engaged with the inner wall of the locking groove 64 , and the locking ball 65 is provided to facilitate limiting the elastic rod 63 .

[0033] Working principle: When the equipment is in use, the user starts the equipment and the material inside the tank body 2 enters the connecting head 4 through the controller 3 for spraying. When the equipment is in use, the user presses the pressure rod 56, and the pressure rod 56 moves, driving the connecting plate 54 to move. When the connecting plate 54 moves, the spring 58 is displaced and deformed to generate elastic force. When the connecting plate 54 moves, the card block 55 is driven to move and disengage from the inside of the first connecting block 52. Then the spray head 51 loses its restraint, and the spray head 51 is pulled out of the inside of the connecting head 4 for replacement. By setting the replacement device 5, the spray head 51 is effectively replaced, which plays a role in quickly replacing the spray head 51, reducing the need for different spray heads 51 to spray different places when the equipment is in use.

When the elastic rod 63 moves, it drives the card ball 65 to move. Then the card ball 65 moves out of the inside of the card slot 64, and then the protective cover 61 is unrestrained. By setting up the protective device 6, the nozzle 51 is effectively protected, which plays a role in protecting the nozzle 51, reduces the risk of foreign matter entering the nozzle 51 after the device is used, causing the nozzle 51 to be blocked and difficult to use normally, thereby improving the practicability of the device.
