Existing foaming devices generally use an air pump to inject air into a container filled with cleaning liquid to generate foam, which is then sprayed out. This type of foaming device requires a certain air pressure before the foam can be sprayed out, and the air pressure in the air chamber is unstable, resulting in uneven foam formation and poor spraying effect. Summary of the Invention

It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0031] like Figure 1 and Figure 2 The diagram shown is a structural schematic of an embodiment of the present invention, which provides an electric spray and foam combination device, including a base 1 and a liquid storage container 2 disposed on the base 1 for storing liquid. The liquid storage container 2 is a backpack-type water tank, and a shoulder strap assembly 20 is provided on the outer wall of the liquid storage container 2 and the base 1. The liquid can be a cleaning solution or a medicine, which can be selected according to the occasion.

[0032] This device combines the functions of spraying and foaming, such as... Figure 3 As shown, a spray foam mechanism and an electrical control mechanism are installed on the base 1. The spray foam mechanism is controlled by the electrical control mechanism. This arrangement can improve the compactness of the structure and facilitate the installation and arrangement of each mechanism.

[0033] like Figure 6 and Figure 7 As shown, the base 1-1 includes a seat body 1-1 and a bottom cover 1-2 that is detachably fixed to the lower end of the seat body 1-1. The seat body 1-1 includes a top cover 1-1a and four side plates 1-1b arranged on the outer periphery of the top cover 1-1a and connected in sequence. The four side plates 1-1b and the top cover 1-1a form an installation space for installing the spray foam mechanism and the electrical control mechanism. The liquid storage container 2 is fixed to the upper end of the four side plates 1-1b and forms a liquid storage space with the top cover 1-1a. The top cover 1-1a is provided with an outlet that connects the liquid storage container 2 and the spray foam mechanism.

[0034] like Figure 4 and Figure 5 As shown, the spray foam mechanism includes a water pump 3 connected to the liquid storage container 2, a water outlet pipe 5 connected to the water pump 3, a nozzle assembly connected to the water outlet pipe 5, and an air pump 4 connected to the water outlet pipe 5. When used for cleaning, the water pump 3 and the air pump 4 are turned on, and air is introduced into the water outlet pipe 5 through the air pump 4 to form foam that is sprayed out from the nozzle assembly. The water pump 3 is a conventional electric sprayer diaphragm pump, and the air pump 4 is a miniature vehicle-mounted air pump. It should be understood that in other embodiments, the air pump 4 can also be installed outside the base 1, for example, externally mounted on the outer wall of the liquid storage container 2, which can also achieve the two-in-one function of spraying foam.

[0035] To facilitate the connection between the water pump 3 and the liquid storage container 2, an inlet connector assembly 12 is provided at the outlet of the liquid storage container 2. The inlet of the water pump 3 is connected to the inlet connector assembly 12 via a first connecting pipe 11.

The pipeline control knob 12-2 is existing technology and can switch between the liquid pipeline and the clean water pipeline inside the liquid storage container. The specific structure has been disclosed in Chinese Patent CN110250142A, and will not be described again in this invention. When the pipeline of the liquid storage container is connected, the pipeline control knob 12-2 can connect the first connecting pipe 11 and the inside of the liquid storage container 2, allowing the liquid in the liquid storage container 2 to flow into the water pump 3. When the clean water pipeline is connected, external clean water can be introduced into the water pump 3 via the self-cleaning water connector 12-1 to perform self-cleaning of the spray foam mechanism.

[0036] To facilitate the connection of the air pump 3, the spray foaming mechanism also includes a three-way connector 9. The air pump 4 is connected to the first interface of the three-way connector 9 via the air inlet pipe 10. The water outlet of the water pump 3 is connected to the second interface of the three-way connector 9 via the second connecting pipe 13. The third interface of the three-way connector 9 is connected to the water outlet pipe 5 via the third connecting pipe 14.

To improve the stability of the structure, the spray foaming mechanism also includes a water outlet connector assembly 15 installed on the side wall of the side plate 1-1b. The water outlet pipe 5 is connected to the third connecting pipe 14 via the water outlet connector assembly 15. The water outlet connector assembly 15 includes a mounting base 15-1 fixed on the side plate 1-1b and a water outlet connector 15-2 provided on the mounting base 15-1. The water outlet pipe 5 is connected to the third connecting pipe 14 via the water outlet connector 15-2.

[0038] To facilitate the fixing of the tee connector 9, the spray foam mechanism also includes a tee fixing seat, on which the tee connector 9 is mounted.

[0039] In order to facilitate the filtration of impurities in the liquid storage container 2 and prevent impurities from entering the water pump 3, a filter valve 19 is provided at the outlet of the liquid storage container 2. The filter valve 19 is existing technology and will not be described in detail in this invention.

[0040] The nozzle assembly includes a spray bar 6 and a nozzle component 7 disposed at one end of the spray bar 6. To facilitate operation of the nozzle assembly, a control handle assembly 16 is also included. The water inlet end of the control handle assembly 16 is connected to the water outlet pipe 5 and the water outlet end is connected to the spray bar 6. The control handle assembly 16 adopts a spray gun commonly used in the prior art, such as the spray gun disclosed in Chinese Patent CN109530121A, which will not be described in detail in this invention.

[0041] In order to fix the spray bar 6, a spray bar fixing seat 21 is provided on the outer wall of the liquid storage container 2.

[0042] The electrical control mechanism includes a power supply 8 and a switching assembly for controlling the water pump 3 and the air pump 4. The water pump 3, the air pump 4, and the switching assembly are electrically connected to the power supply 8. In this example, the power supply 8 is a battery pack, and a battery pack mounting seat is provided in the base 1 to fix the battery pack 8.

[0043] To facilitate the control of the operation of water pump 3 and air pump 4, the switch assembly includes a water pump control switch 17 and an air pump control switch 18 fixed on the outer wall of the side plate 1-1b, which can control water pump 3 and air pump 4 respectively, making operation convenient.

[0044] The working principle of this invention is as follows:

[0045] For example, when this two-in-one device is used in the field of pesticide spraying, the pesticide solution is placed in the storage container 2, and the water pump 3 is turned on and the control handle assembly 16 is used to spray the pesticide solution to achieve the spraying function; when this two-in-one device is used in the field of cleaning, the storage container 2 is filled with cleaning agent diluted with water, and the water pump 3 and air pump 4 are turned on at the same time. By operating the control handle assembly 16, continuous and uniform foam can be generated at the nozzle component 7 to achieve the foam spraying function.

[0046] In summary, this two-in-one device can achieve the functions of spraying and foaming, and the sprayed foam is uniform and continuous, improving work efficiency and foaming effect.
