Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0038] like Figure 1 and Figure 5 As shown in the figure, this embodiment provides a lightweight melon spraying device, including a spray cylinder 1, a handle 2 on the outside of the spray cylinder 1, a handle 3 on the outside of the spray cylinder 1 near the handle 2, and the handle 2 and handle 3 are on the same straight line. A connecting pipe 4 is provided at one end of the spray cylinder 1, a foam sponge 5 is provided on the outside of the handle 2, a gravity ball assembly 6 is provided at one end of the connecting pipe 4, a long spray bar placement assembly 7 is provided on the outside of the spray cylinder 1 away from the handle 2, a short spray bar assembly 8 is provided at the other end of the spray cylinder 1, and a flange connection assembly 9 is provided between the spray cylinder 1 and the connecting pipe 4.

[0039] The long spray bar placement assembly 7 includes a long spray bar 71, one end of which is provided with a first thread 72. A first limiting block 73 is provided on the long spray bar 71. Support blocks 74 are provided on the outer side of the spray cylinder 1. A U-shaped slot 75 is provided on the support block 74. The long spray bar 71 is adapted to the U-shaped slot 75. A locking mechanism is provided on the U-shaped slot 75. By locking the spare long spray bar 71 into the U-shaped slot 75 on the support block 74, the problem of the spare spray bar being inconvenient to carry is solved.

[0040] The locking mechanism includes a storage chamber 76, with two storage chambers 76 respectively located on both sides of the U-shaped slot 75. A locking block 77 is provided inside the storage chamber 76, and a sliding rod 78 is provided at one end of the locking block 77. The sliding rod 78 is slidably connected to the storage chamber 76, and a spring 79 is sleeved on the outer surface of the sliding rod 78. The spring 79 is located between the locking block 77 and the storage chamber 76. A circular plate 710 is provided at one end of the sliding rod 78. When the long spray rod 71 moves downward, it will push the locking block 77 towards the storage chamber 76. At the same time, the locking block 77 will squeeze the spring 79 to generate tension. After the long spray rod 71 is locked in place, the tension of the spring 79 will push the locking block 77 back to the initial position, thereby playing a hard limiting role for the long spray rod 71.

[0041] The card block 77 has sliders 711 on both sides, and the storage chamber 76 has symmetrical grooves 712 on the inner wall. The sliders 711 and the grooves 712 are slidably connected, and the grooves 712 guide the sliders 711 on the card block 77.

[0042] like Figure 1 , Figure 2 and Figure 4 As shown, the short spray bar assembly 8 includes a short spray bar 81, which is threadedly connected to the spray cylinder 1. The short spray bar 81 is provided with a second limiting block 82, and one end of the short spray bar 81 is provided with a second thread 83. A protective cover 84 is slidably connected to the short spray bar 81, and one end of the short spray bar 81 is provided with a mounting nut 85. The protective cover 84 is located between the second limiting block 82 and the mounting nut 85. By fitting the protective cover 84 onto the end of the short spray bar 81 with the second limiting block 82 until the protective cover 84 abuts against the second limiting block 82, the mounting nut 85 is then screwed in through the second thread 83. The mounting nut 85 limits the position of the protective cover 84, and the protective cover 84 can be used for both long and short spray bars.

[0043] like Figure 1 and Figure 5 As shown, the flange connection assembly 9 includes a first flange 91, which is located at the other end of the connecting pipe 4. A second flange 92 is located at one end of the spray cylinder 1. The front end of the first flange 91 is inserted into the interior of the second flange 92. A sealing ring 93 is provided between the first flange 91 and the second flange 92. A pressing mechanism is provided on one side of the first flange 91. By inserting the first flange 91 into the second flange 92, and with the sealing ring 93 between the first flange 91 and the second flange 92, the connection between the spray cylinder 1 and the connecting pipe 4 is achieved.

[0044] The extrusion mechanism includes guide rods 94. Two sets of guide rods 94 are located on one side of the second flange 92, and the guide rods 94 extend through the sealing ring 93 to the outside of the first flange 91. One end of the guide rod 94 is provided with a horizontal plate 95, and the horizontal plate 95 is threadedly connected to the extrusion column 96. The extrusion column 96 abuts against the first flange 91, and pushes the first flange 91 through the extrusion column 96, so that the sealing ring seals more tightly between the first flange 91 and the second flange 92, and avoids leakage.

[0045] like Figure 1 and Figure 6 As shown, the gravity ball assembly 6 includes a gravity ball body 61, a filter screen 62 at the bottom of the gravity ball body 61, a connecting post 63 on the outer surface of the gravity ball body 61 opposite to the filter screen 62, and the connecting post 63 is connected to one end of the connecting pipe 4. The outer surface of the connecting post 63 is provided with several limiting buckles 64, and the liquid is filtered through the filter screen 62 inside the gravity ball body 61.

[0046] In use, the operator inserts the spare long spray bar 71 into the U-shaped slot 75 on the support block 74. The long spray bar 71 will push the locking block 77 to move along the slide 712 towards the storage chamber 76. At the same time, the locking block 77 will compress the spring 79 to generate tension. After the long spray bar 71 is locked in place, the tension of the spring 79 will push the locking block 77 back to the initial position, thus playing a hard limiting role for the long spray bar 71. To prevent the spare long spray bar 71 from falling off, the problem of the spare spray bar being inconvenient to carry is solved, and the risk of losing the spray bar is also avoided, which is beneficial to the subsequent operation of the device. At the same time, the short spray bar 81 is screwed to the other end of the spray cylinder 1, and then the protective cover 84 is put on the end of the short spray bar 81 with the second limiting block 82 until the protective cover 84 abuts against the second limiting block 82. Then, the mounting nut 85 is screwed in through the second thread 83. The mounting nut 85 limits the protective cover 84, and the protective cover 84 can be used for both long and short spray bars to prevent the liquid from splashing onto the workers during the spraying process and to prevent the liquid from flowing down the spray bar. Finally, the first flange 91 is inserted into the second flange 92, with a sealing ring 93 between the first flange 91 and the second flange 92. Simultaneously, the extrusion column 96 is turned, pushing the first flange 91. At this time, the horizontal plate 95, through the guide rod 94, moves the second flange 92 closer to the first flange 91, ensuring a tighter seal between the first flange 91 and the second flange 92, preventing leakage. Next, the operator places the filterable gravity ball assembly 6 into the liquid. The liquid is filtered through the internal filter screen 62 of the gravity ball body 61, preventing the connecting pipe from falling out of the container during use and filtering any impurities accidentally mixed into the liquid, preventing them from clogging the nozzle. The operator holds the handle 2, which is wrapped with foam sponge 5 to increase friction, enhancing stability and comfort during operation, facilitating operation. Then, the operator squeezes the sprayer handle 3, spraying the liquid from the nozzle onto the young melon fruits.
