Technical Field

[0001] This utility model belongs to the field of termite control technology, and in particular relates to a portable termite control spray device. Background Technology

[0002] Termites bore into synthetic fibers, plastics, wires, cables, and even bricks, stones, and metals. They corrode and melt these objects by expelling chemicals like formic acid. Termites are highly destructive insects, and to control them, pesticide spraying devices are typically used.

[0003] To improve the convenience of spraying equipment, existing equipment uses backpack-style designs instead of mobile ones, thus avoiding situations where spraying cannot be completed due to limited space. However, in order to improve spraying efficiency, existing backpack-style equipment typically carries the liquid on the user's back. But because the liquid is heavy, carrying it for a long time can cause shoulder fatigue, making it impossible for the user to work for extended periods. Furthermore, existing equipment cannot adjust the pressure of the backpack-style equipment, thus affecting its use. For example, the aforementioned problem exists in patent number CN202322411251.6, which results in excessive pressure during use, thus affecting the equipment's usability. Utility Model Content

Two carrying straps 3 are fixedly provided on the front side of the back plate 1. It also includes:

[0023] A buffer assembly, set on the back plate 1, is used for buffering the sprayer 2. It includes two first springs 5 ​​fixedly set on the back plate 1. The ends of the first springs 5 ​​are fixedly connected to a slider 6 that is slidably set in the back plate 1. The sprayer 2 is fixedly set on the slider 6.

[0024] An inflatable assembly, mounted on the back panel 1, is used to mitigate the downward pressure of the sprayer 2. It includes a back airbag 7 mounted on one side of the back panel 1 and a shoulder airbag 8 mounted on the inside of the shoulder strap 3, with the back airbag 7 and the shoulder airbag 8 being connected through each other.

[0025] As a preferred embodiment of this utility model, the buffer assembly further includes a groove 4 formed on the back plate 1, a first spring 5 fixedly disposed in the groove 4, and a slider 6 simultaneously slidably disposed in the groove 4, for controlling the moving direction of the sprayer 2 and preventing it from shifting when moving up and down, thus causing its center of gravity to change.

[0026] As a preferred embodiment of this invention, the inflation assembly further includes an air pressure rod 9 mounted on the back panel 1 for inflating the back airbag 7 and shoulder airbag 8. The air pressure rod 9 includes a piston rod and a gas generating rod. The piston rod is slidably disposed inside the gas generating rod, and the end of the piston rod is fixedly disposed on the sprayer 2. The end of the gas generating rod is fixedly disposed on the back panel 1. The back panel 1 is provided with a control component for controlling the gas discharge of the back airbag 7 and providing gas to the airbag. When the sprayer 2 swings up and down, it can effectively keep the airbag inflated, thereby improving the comfort of the shoulders and back.

[0027] As a preferred embodiment of this utility model, the control component includes a solenoid valve 10 that passes through the back airbag 7 and a second spring 11 that is fixedly disposed at the end of the piston rod. The second spring 11 has two contactors 12 that are in active contact inside, which are used to control the opening and closing of the solenoid valve 10, so as to control the gas discharge in the airbag, thereby the airbag can form a cycle of inflating and deflating.

[0028] As a preferred embodiment of this utility model, each of the two shoulder straps 3 is fixedly provided with a reinforcing strap 13, and a lock head 14 is installed at the end of each of the two reinforcing straps 13. The two lock heads 14 are movably connected to ensure the stability of the two shoulder straps 3 and make the shoulder straps 3 more stable when in use.

[0029] The working principle of this utility model:

[0030] refer to Figure 1 The liquid to be sprayed is injected into the sprayer 2, and then it is carried on the shoulder using the shoulder strap 3. When the equipment is on the operator's shoulder, the weight of the sprayer 2 will press down. Figure 3 The slider 6 slides in the groove 4. When the slider 6 moves down, the first spring 5 is compressed, and at the same time, the piston rod in the pressure rod 9 of the sprayer 2 descends. At this time, the second spring 11 is stretched, and the contactor 12 disengages, which in turn closes the solenoid valve 10. When the piston rod descends, its displacement in the gas generating rod compresses the air, causing the air to enter the back airbag 7 and the shoulder airbag 8, inflating them and thus pushing the shoulder strap 3 away from the shoulder. Then the operator... Figure 2 Once the two locks 14 are locked, the entire equipment can be carried on the operator's back, thus enabling the equipment to be moved. The liquid sprayed by the sprayer 2 can then effectively kill the termites.

[0031] refer to Figure 3 When the operator carries the equipment, the movement of the human body generates a swinging force, which pushes the sprayer 2 to swing. When the swinging force swings, the first spring 5 will repeatedly compress and recover, thus effectively buffering the sprayer 2 and further preventing the sprayer 2 from being too heavy and impacting the user's shoulders. During the swinging process of the sprayer 2, the piston rod inside the air pressure rod 9 moves up and down at the same time. When the piston rod moves up, the second spring 11 shortens, and the contactor 12 contacts, thereby opening the solenoid valve 10. When the solenoid valve 10 is open, the gas in the airbag is discharged. When the sprayer 2 drives the piston rod to move down, the gas re-enters the airbag, and the solenoid valve 10 closes at this time. This repeated operation can realize the inflation and deflation of the airbag, further improving the comfort of its use.

[0032] This invention utilizes the up-and-down sliding of the sprayer 2 on the back plate 1, combined with the buffering force of the first spring 5, to effectively reduce the pressure on the operator's shoulders. This prevents shoulder injury caused by excessive weight of the sprayer 2. At the same time, the repeated movement of the sprayer 2 inflates and deflates the shoulder airbag 8 and the back airbag 7, creating a cyclical working process of inflation and deflation, thereby further improving the user's experience and preventing excessive pressure on the shoulder straps 3, which could lead to user discomfort.
