Abstract
Description
Technical Field
[0001] The utility model relates to the field of liquid sprayers, in particular to a small liquid sprayer with a leak-proof function. Background Art
[0002] Liquid sprayers are mechanical devices that disperse liquids into a mist. They are widely used in agriculture, cleaning, disinfection, and other fields. Liquid sprayers can be divided into three types based on their power source: manual, electric, and pneumatic. Manual sprayers rely on human power and are suitable for small-scale or home use; electric sprayers are powered by batteries or a mains supply and are suitable for medium-scale operations; and pneumatic sprayers use gas for large-scale or professional applications.
[0003] Small liquid sprayers commonly found on the market still have unsprayed droplets inside after spraying. This results in the remaining droplets inside the small liquid sprayer dripping due to gravity when the small liquid sprayer is tilted, causing leakage. The leaked droplets adhere to the surface of the device, corroding the surface of the device and easily contaminating everywhere, reducing the practicality of the device. Utility Model Content

[0016] The utility model has the following beneficial effects:
[0017] 1. Compared with the prior art, this small liquid sprayer with a leak-proof function is equipped with a lifting rod, a first sealing block, a connecting rod, and a second sealing block. During use, when the liquid inside the device needs to be sprayed out, the pressing head is pressed, and the connecting block fixed inside the pressing head moves downward, driving the lifting rod fixed to the lower surface of the connecting block to move downward. At this time, the first sealing block fixed at the end of the lifting rod moves downward, and a gap is generated between the first protrusion that fits with the upper surface of the first sealing block and the first sealing block. Similarly, a gap is also generated between the second sealing block installed at the end of the connecting rod fixed to the surface of the lifting rod and the second protrusion. The air pressure inside the device is greater than the external air pressure, and the airflow in the device drives the liquid through the third connecting pipe fixed on the right surface of the second connecting pipe into the nozzle and then is sprayed out by the nozzle. When the pressing head is released, the lifting rod drives the first sealing block back to its original position, and the connecting rod and the lifting rod rise at the same time, so that the upper surface of the second sealing block fixed at the end of the connecting rod fits into the lower surface of the second protrusion, and the third connecting pipe inside the device, where liquid droplets are most likely to remain, is sealed. Compared with conventional devices, there are still liquid droplets that have not been sprayed inside after spraying. This results in that when the small liquid sprayer is tilted, the liquid droplets remaining inside the small liquid sprayer will drip due to gravity, causing leakage. The leaked liquid droplets adhere to the surface of the device, corrode the surface of the device, and are easily contaminated everywhere, reducing the practicality of the device. The device can use the cooperation of the second sealing block and the second protrusion to prevent the residual liquid droplets inside the device from flowing out, thereby improving the practicality of the device.
[0018] 2. Compared with the prior art, this small liquid sprayer with a leak-proof function is equipped with a lifting rod, a second sealing ring, and a second connecting tube. During use, one end of the second sealing ring is fixed to the surface of the lifting rod, and the other end of the second sealing ring is fixedly connected to the upper surface of the second connecting tube. The second sealing ring is elastic, so that the second sealing ring can well ensure the sealing of the connection between the second connecting tube and the lifting rod when the lifting rod rises or falls during use, thereby improving the practicality of the device.
