[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 As shown, a multi-functional backpack sprayer includes a liquid storage tank 1, a liquid outlet pipe 2, a pair of connecting pipes 3, a connector 4, a spray pipe 5, and a spray gun 6.

[0018] like Figure 1 As shown, the storage tank 1 is used to store protective liquid. The storage tank 1 is equipped with a shoulder strap 11 and an abdominal strap 12 for carrying and securing the storage tank 1 in a back-carrying manner. The liquid outlet pipe 2 is vertically connected to the storage tank 1 and is used to discharge the protective liquid inside the storage tank 1 outward along the liquid outlet pipe 2 after the storage tank 1 is pressurized.

[0019] like Figure 1 , Figure 2 As shown, the liquid storage tank 1 is provided with a liquid injection port 13, and a filter screen 14 is provided inside the liquid injection port 13 to achieve automatic filtration of protective liquids with different mesh sizes during the addition of protective liquid, so as to achieve stable spraying of protective liquid.

[0020] like Figure 1 , Figure 2 As shown, the filter screen 14 includes a frame 15 and a net bag 16. The frame 15 is embedded in the liquid injection port 13, and a locking clip 17 is provided in the liquid injection port 13 for embedding the frame 15. The net bag 16 is provided on the frame 15 to enable quick assembly and disassembly of the filter screen 14 and to allow for free replacement of filter screens 14 with different pore sizes.

[0021] like Figure 1 , Figure 3 As shown, a pair of connecting pipes 3 are arranged in an L-shape and are connected to both sides of the outlet pipe 2. The connector 4 includes a single-pipe connector 41 and a double-pipe connector 42, both of which are vertically slidably connected to the vertical section of the connecting pipe 3.

[0022] like Figure 3 As shown, both the single-pipe connector 41 and the double-pipe connector 42 have a connection port 43 on their lower sidewalls for connecting the horizontal section of the connecting pipe 3. A plug rod 31 is horizontally threaded onto the connecting pipe 3, and both the upper and lower outer walls of the single-pipe connector 41 and the double-pipe connector 42 have insertion holes 44 for inserting the plug rod 31.

[0023] like Figure 1 , Figure 4 As shown, the nozzle 5 includes a single flexible hose 51 and a double flexible hose 52. The single flexible hose 51 and the double flexible hose 52 are respectively sleeved on the outer walls of the single pipe connector 41 and the double pipe connector 42, and are fixed by clamps. The spray gun 6 includes a single spray bar 61 and a double spray bar 62. The lower end of the single spray bar 61 and the double spray bar 62 are provided with a handle 63. The handle 63 is provided with a pipe head 64 that connects to the single flexible hose 51 and the double flexible hose 52, respectively.

[0024] When directional spraying is required in a confined space, the single hose 51 is removed and then fitted onto the single pipe connector 41, secured with a clamp. The single spray bar 61 is then removed, connecting the single hose 51 to the nozzle 64 on the single spray bar 61. The single pipe connector 41 is then slid downwards, connecting the connection port 43 on the single pipe connector 41 to the connecting pipe 3. The insertion rod 31 is then inserted into the insertion hole 44 at the upper end of the single pipe connector 41, achieving connection and fixation between the single pipe connector 41 and the connecting pipe 3. This ensures that the protective liquid in the outlet pipe 2 can only be sprayed along the single pipe connector 41, thus satisfying the requirement for directional spraying in confined spaces.

[0025] When efficient spraying of a large area is required, remove the double hose 52, then slip the double hose 52 onto the double pipe connector 42 and secure it with a clamp. Next, remove the double spray bar 62 and connect the double hose 52 to the pipe head 64 on the double spray bar 62. Then, control the double pipe connector 42 to slide downwards, connecting the connection port 43 on the double pipe connector 42 to the connecting pipe 3. Then, control the insertion rod 31 to insert into the insertion hole 44 at the upper end of the double pipe connector 42, achieving connection and fixation between the double pipe connector 42 and the connecting pipe 3. This ensures that the protective liquid in the outlet pipe 2 can only be sprayed along the double pipe connector 42, thus meeting the requirement for efficient spraying of a large area.

[0026] In actual operation, the single hose 51 and the double hose 52 can be connected at the same time, and equipped with a single spray bar 61 and a double spray bar 62, so that the protective liquid in the outlet pipe 2 can be sprayed out along the single pipe joint 41 and the double pipe joint 42, allowing the operator to hold both or two operators to hold one, thus meeting the needs of synchronous spraying in narrow spaces and large areas.

[0027] Therefore, by setting a single pipe connector 41 and a double pipe connector 42 on the liquid outlet pipe 2, different spray pipes 5 and spray guns 6 can be matched according to the usage requirements. It is possible to achieve directional spraying in narrow spaces using a single hose 51 and a single spray bar 61, and to achieve large-area spraying using a double hose 52 and a double spray bar 62, thereby improving construction efficiency and meeting the free switching of different usage requirements, thus improving the practicality of the entire sprayer.

[0028] like Figure 4 , Figure 5 As shown, an extension rod 7 is rotatably connected to the front end of the handle 63. A clamp 71 for holding the spray gun 6 is provided on the extension rod 7. A locking mechanism 8 is provided at the rear end of the handle 63 to fix the extension rod 7 after it is flipped.

[0029] like Figure 5 , Figure 6 As shown, the locking mechanism 8 includes a fixed clamp 81 and a movable clamp 82. The fixed clamp 81 is mounted on the handle 63. One end of the movable clamp 82 is rotatably connected to the fixed clamp 81, and the other end is provided with a hook 83. The fixed clamp 81 is provided with a hole 84 for the hook 83 to pass through.

[0030] When the extension rod 7 is not needed, it can be flipped to the side of the spray gun 6, allowing the clamp 71 to hold the spray gun 6, thus completing the storage and fixation of the extension rod 7. When spraying operations are required at a long distance, the extension rod 7 can be flipped 180°, embedding it into the fixing clamp 81. Then, the movable clamp 82 can be flipped, allowing the hook 83 to be inserted into the locking hole 84, thus clamping and fixing the extension rod 7. At this time, the operator can hold the extension rod 7 for spraying operations, enabling adjustment of the length of the spray gun 6 to meet the needs of long-distance work, thereby improving the overall practicality of the sprayer.

[0031] like Figure 5 As shown, the extension rod 7 includes a tube body 72 and a rod body 73. The tube body 72 is rotatably connected to the handle 63, and the rod body 73 is slidably connected to the tube body 72. A locking pin 74 for pressing the rod body 73 is threaded onto the tube body 72.

[0032] By setting a telescopic extension rod 7, the extension rod 7 of different lengths can be freely adjusted to meet different usage needs and improve practicality.

[0033] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
