[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] Please see Figure 1-4 This utility model provides a technical solution: Example 1, please refer to Figure 1 , 2 3. An electric foam air-liquid dual-pump sprayer includes a sprayer body 1 and a base 2. The sprayer body 1 has a threaded mating end on its upper part. The base 2 is detachably connected to the bottom of the sprayer body 1. Specifically, at least two symmetrical side grooves 19 are provided on the lower side of the sprayer body 1. Two locking posts 20 are correspondingly provided on the inner side of the base 2. The locking posts 20 and the side grooves 19 are engaged to achieve a stable connection between the base 2 and the sprayer body 1, making the base 2 easy to disassemble, assemble, maintain or replace. A side opening 18 is also provided on the upper side of the sprayer body 1. A screw cap 9 is screwed onto the outside of the side opening 18. This design provides a convenient liquid filling port, allowing users to replenish liquid without opening the entire top cover.

[0022] The top cover is screwed onto the upper end of the kettle body 1. The top cover is mainly composed of a connecting ring 3 and a top cover 4. The connecting ring 3 has a vertical partition inside, which divides its interior into two independent chambers: a water pump mounting slot 17 and an air pump mounting slot 22. The top cover 4 is fitted onto the top of the connecting ring 3 by a snap-fit ​​mechanism.

[0023] The power system includes a water pump 13 and an air pump 14, which are respectively installed in the water pump mounting slot 17 and the air pump mounting slot 22. The input end of the water pump 13 is connected to a suction pipe 15, which extends downward, passes through the connecting ring 3 and reaches the bottom of the kettle body 1 to ensure that the liquid can be fully drawn in. The output ends of the water pump 13 and the air pump 14 are respectively delivered to the nozzle assembly through an independent connecting pipe 16.

[0024] The nozzle assembly is located on one side of the top cover and typically contains an atomizing nozzle and a foam generating chamber. In this embodiment, nozzle a is preferred, with its end flattened. In spray mode, only liquid is pumped to the atomizing nozzle to form a mist spray. In foam mode, liquid and air are fully mixed and sheared in the foam generating chamber to finally generate fine foam before being sprayed out.

[0025] The handle 5 is located on the other side of the top cover, and has an internal mounting cavity 12. The mounting cavity 12 integrates a control circuit board 10 and a battery 11. The battery 11 is a rechargeable lithium battery that powers the entire system. The control circuit board 10 is electrically connected to the water pump 13 and the air pump 14 via wires to control their start / stop and operating power. Several operation buttons, such as a power button and a mode switch button, are soldered onto the control circuit board 10. These operation buttons are exposed through corresponding slots in the top cover 4 for user operation. Additionally, a USB port is included. 8 is also connected to the control circuit board 10, with its port exposed in the housing for charging the battery 11. Several operation buttons include a mixing button 7, a spray button 24, and a jet button 25, which respectively realize foam generation, spraying and blowing operations. When the mixing button 7 is pressed, the water pump 13 and the air pump 14 start simultaneously to realize the foam generation function. When the spray button 24 is pressed, only the water pump 13 starts to realize the spraying function. When blowing is required, the dust, small debris and some sewage can be blown away by pressing the jet button 25.

[0026] Example 2, please refer to Figure 4 In this embodiment, the nozzle assembly is preferably nozzle b23, the end of which is cylindrical.

[0027] Working principle: Users select the working mode through several operation buttons. When the spray mode is selected, the control circuit board 10 is activated by the spray button 24 to start only the water pump 13. The water pump 13 draws the liquid in the bottle 1 through the suction pipe 15 and pumps it into the nozzle assembly through the connecting pipe 16. The atomizing nozzle breaks the liquid into fine droplets and sprays it out.

[0028] When the foam mode is selected, the water pump 13 and the air pump 14 are started simultaneously by the control circuit board 10 through the mixing button 7. The water pump 13 pumps out liquid, and the air pump 14 pumps out air. The two fluids are transported to the foam generation chamber in the nozzle assembly through their respective connecting pipes 16. In the foam generation chamber, the liquid and air are violently mixed and sheared in a specific structure to form uniform and stable foam before being sprayed out. When it is necessary to blow away dust, small debris, or sewage, press the air jet button 25. The control circuit board 10 will start the air pump 14, generating airflow that is sprayed out through the nozzle.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
