Description

Technical Field

[0001] This utility model specifically relates to a sprayer capable of continuous spraying. Background Technology

[0002] A sprayer is short for spraying equipment. A sprayer is a device that uses air suction to turn medicine or other liquids into a mist and spray it evenly onto other objects. It consists of a compressed air device, a thin tube, a nozzle, etc.

[0003] In most sprayers on the market, the liquid and gas inside the cylinder are in the same cavity. When the device is tilted, the free end of the bottom drain pipe is easily exposed to the air, which can cause intermittent spraying and affect the device's performance. Therefore, a sprayer is needed to ensure that the device can spray continuously when tilted and avoid intermittent spraying when the device is tilted. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sprayer capable of continuous spraying.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0021] Example

[0022] A sprayer capable of continuous spraying, such as Figure 1-3 As shown, it includes a bottle body 1, a pressing and dispensing mechanism 2 mounted on the bottle body 1, and a pressing cap 3 mounted on the pressing and dispensing mechanism 2.

[0023] The press-and-jet mechanism 2 includes a threaded cap 21, a nozzle 22 whose upper end passes through the threaded cap 21 and is inserted into the press cap 3, a piston cylinder 23 located below the threaded cap 21 and fitted onto the lower end of the nozzle 22, a piston component 24 located inside the piston cylinder 23 and fitted onto the lower end of the nozzle 22, a short spring 25 fitted onto the lower end of the nozzle 22 for pressing down the piston component 24, a spring seat 26 located inside the piston cylinder 23 and embedded into the lower end of the nozzle 22, a long spring 27 located at the bottom of the piston cylinder 23 and supporting the spring seat 26 at its upper end, and a spring located inside the piston cylinder. The piston cylinder 23 has a steel ball 28 at the bottom and a straw 29 inserted at the lower end of the piston cylinder 23 and extending to the bottom of the bottle body 1. The upper end of the piston cylinder 23 is fitted with a sealing cover 231. An O-ring 232 for abutting the nozzle 22 is provided on the inner side of the sealing cover 231. The lower end of the piston cylinder 23 has an integrally formed inner cylinder step 233 that restricts the movement of the piston 24. The lower end of the piston cylinder 23 has an elliptical pressurizing chamber 234 that accommodates the steel ball 28. The lower end of the piston cylinder 23 also has a straw insertion port 235 that communicates with the pressurizing chamber 234.

[0024] The upper end of the threaded cap 21 has an integrally formed extension 211 for accommodating the pressing cap 3. The upper end of the threaded cap 21 has an integrally formed mounting seat 212 that protrudes to the extension 211 for assembling the nozzle 22 and piston cylinder 23. The inner bottom of the threaded cap 21 has a sealing gasket 213 that is tightly attached to the mounting seat 212. Specifically, after the upper end of the piston cylinder 23 is fitted with a sealing cover 231 and an O-ring 232, it is snapped under the mounting seat 212. The sealing cover 231 and the O-ring 232 improve the installation sealing of the nozzle 22 and the piston cylinder 23, while the sealing gasket 213 is squeezed by the mounting seat 212, which can improve the sealing between the threaded cap 21 and the bottle body 1.

[0025] The upper end of the nozzle 22 is integrally formed with a protruding ring 221. Specifically, the protruding ring 221 can prevent the nozzle 22 from being pulled out of the threaded cap 21 and can abut against the short spring 25, which can squeeze the short spring 25 to make the downward piston 24 move downward.

[0026] The lower end of the nozzle 22 has an outer nozzle step 222 for mounting a piston component 24.

[0027] The piston component 24 has an integrally formed pressure ring 241 at the lower end of its inner ring, and an inner step 242 for mounting the nozzle 22 is provided on the upper inner side of the pressure ring 241.

[0028] A sealing ring 261 is integrally formed on the side of the spring seat 26. Specifically, when the long spring 27 pushes up the spring seat 26, the sealing ring 261 contacts the pressure ring 241 of the piston component 24 to seal and prevent liquid flow.

[0029] The upper end of the spring seat 26 is integrally formed with an insert post 261. Specifically, the insert post 261 can be inserted into the lower end of the nozzle 22 and fixed.

[0030] A liquid flow channel 263 is provided on one side of the embedded column 261. Specifically, the upper end of the liquid flow channel 263 is connected to the nozzle 22, and the lower end of the liquid flow channel 263 is connected to the pressurization chamber 234 after the sealing ring 261 is separated from the pressure ring 241 of the piston component 24.

[0031] Steel ball 28 is typically used as a valve or sealing device, its main function being to control the flow of liquid and ensure that the liquid can be smoothly ejected when pressed.

[0032] The lower end of the press cap 3 is integrally formed with a nozzle connector 31. The press cap 3 has an ejection chamber 32 that communicates with the nozzle connector 31, and a nozzle 33 is embedded in the ejection chamber 32.

[0033] like Figure 4 As shown, and in combination Figure 1-3 When the sprayer is in use, the press cap 3 is squeezed. At this time, the short spring 25 presses down the piston 24 and moves it downward. After the piston 24 comes into contact with and is restricted by the inner step 233 of the cylinder, the nozzle 22 can continue to move downward a certain distance. Then the outer step 222 of the nozzle comes into contact with the inner step 242 of the pressure ring of the piston 24. At this time, the sealing ring 261 disengages from the pressure ring 241 of the piston 24. The liquid flow channel 263 connects the nozzle 22 and the pressurization chamber 234. The high-pressure liquid stored in the pressurization chamber 234 will enter the nozzle 22 through the liquid flow channel 263 and then be transported by the nozzle 22 to the spraying chamber 32 of the press cap 3 and atomized and sprayed out through the nozzle 33.

[0034] It should be further explained that the inlet radius of the straw insertion port 235 is larger than that of the liquid flow channel 263. Therefore, the liquid inside the bottle 1 is compressed by high-pressure gas. The liquid is transported from the straw 29 to the pressurization chamber 234 for pressurization, and then transported through the liquid flow channel 263.

[0035] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
