[0002] At present, many similar products such as PA pots are popular in the market. The PA pot can mix water, cleaning agent and air to form a large amount of foam, and spray these foams evenly over a large area on the surface of an object, thus greatly improving the efficiency of people's cleaning work, so it is loved by some people.

[0003] The prior art still has the following deficiencies:

[0004] 1. The functions of the pressurized foam pots on the market are relatively single at present, and there may be a situation where the utilization rate is not high when users buy them home.

[0005] 2. The handle of the water pot is usually fixed. When cleaning some lower positions, such as the bottom of a car or the bottom of a cabinet, it is necessary to ensure that the nozzle assembly is lifted up at a certain angle to improve the cleaning effect. However, in this state, the posture of the user holding the water pot is not comfortable.

[0006] 3. The current PA pots on the market pressurize the water storage tank, so that the air pressure in the water storage tank increases, and the liquid in the water storage tank is squeezed out of the water storage tank. In this process, the inside of the water storage tank will bear a huge pressure, making the surface of the water storage tank face the risk of rupture.

[0007] 4. After the water storage tank is damaged, since a high-pressure environment cannot be formed inside, the liquid in the water storage tank cannot be squeezed out either, affecting the normal use of the equipment. Content of the Utility Model

[0059] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the drawings, but the present invention is not limited to these embodiments.

[0060] As shown in Figure 1 and Figure 2 A pressurized sprayer includes a housing 6. A spray head assembly 4 is provided at the front end of the housing 6. A control assembly, a water pump assembly 2 and an air pump assembly 3 are arranged inside the housing. The control assembly is electrically connected to the water pump assembly 2 and the air pump assembly 3. Both the water pump assembly 2 and the air pump assembly 3 are connected to the spray head assembly 4 and can spray water, air or mixed bubbles from the spray head assembly 4.

[0061] Among them, the control assembly includes a water pump and air pump control switch 23 and a power switch 35.

[0062] As a preferred embodiment, the water pump and air pump control switch 23 is a touch switch. By pressing the water pump and air pump control switch 23 in different ways, different working signals can be sent, so as to realize the control of the water pump assembly 2 and the air pump assembly 3 by the water pump and air pump control switch 23 respectively, and the operation is simple and convenient.

[0063] When water spraying operation is required, long press the water pump and air pump control switch 23 to control the water pump assembly 2 to work, so that the water pump assembly 2 can work alone without turning on the air pump assembly 3.

[0064] Short pressing the water pump and air pump control switch 23 can control the air pump assembly 3 and the water pump assembly 2 to start at the same time.

[0065] When blowing or suction is required, the water storage tank 5 needs to be removed from the housing 6 first, and then the air pump assembly 3 and the water pump assembly 2 are started by short pressing the water pump and air pump control switch 23. Since the water storage tank 5 is removed, it is possible to prevent the water pump assembly 2 from pumping the water in the water storage tank 5 and making the water enter the mixing joint 1, ensuring that only air flow passes through the mixing joint 1 and is sprayed out through the spray head assembly 4.

[0066] When foam needs to be sprayed, the water storage tank 5 needs to be connected, or the water pump assembly 2 should be able to draw water from the water source. Briefly press the control assembly to control the water pump assembly 2 and the air pump assembly 3 to work simultaneously. After the air flow and the water flow enter the mixing joint 1 for mixing, they are sprayed out through the nozzle assembly 4.

[0067] Furthermore, a grip 9 is also connected to the housing 6, and the water pump and air pump control switch 23 is arranged on the grip 9. Since in the air-jet state, the air flow will not contaminate the surface of other items, it will not bring unnecessary trouble to the user.

[0068] As a preferred embodiment, the power switch 35 is arranged on the side of the housing 6; the position where the power switch 35 is arranged is inside the grip 9, so that the grip 9 can block the outside of the power switch 35.

[0069] Since the water pump and air pump control switch 23 is a touch switch, there will be a situation of accidental touch in actual use.

[0070] By separately setting the power switch 35 to control the closing or opening of the circuit, it can effectively prevent the situation that the device works due to accidental touch of the water pump and air pump control switch 23. And arranging the power switch 35 below the grip 9 can make the grip 9 play the role of blocking the power switch 35, thereby reducing the probability that the power switch 35 is also accidentally touched and activated, and improving the safety when using the spray bottle.

[0071] When the user uses the spray bottle, usually the hand holds the grip 9. Therefore, when the user needs to spray water or foam, it can be conveniently controlled whether to turn on the water pump assembly 2 through the water pump and air pump control switch 23 on the grip 9, so as to achieve the purpose of quickly and conveniently controlling whether the spray bottle sprays water or foam, which is convenient for the user to use.

[0072] As Figures 1-3 shown, the grip 9 is hinged to the end of the housing 6.

[0073] In this embodiment, a first annular tooth groove 91 is formed at the end of the grip 9, and a gear hinge 94 is movably arranged inside the first annular tooth groove 91.

[0074] A pressing part 95 is arranged at the end of the gear hinge 94, and the gear hinge 94 can be pushed to move through the pressing part 95.

[0075] A second annular tooth groove 62 is formed at the end of the housing 6. When the first annular tooth groove 91 and the second annular tooth groove 62 are aligned, a part of the gear hinge 94 can be partially placed in the first annular tooth groove 91, and another part of the gear hinge 94 can be placed in the second annular tooth groove 62, so that the grip 9 is connected to the housing 6.

[0076] At this time, by pressing the pressing part 95, the gear hinge 94 can be pushed to move within the first annular tooth groove 91 and the second annular tooth groove 62. When a part of the gear hinge 94 completely enters the first annular tooth groove 91 from the second annular tooth groove 62, at this time, the grip 9 and the housing 6 are separated, enabling the grip 9 to rotate relative to the housing 6.

[0077] After rotating a certain angle, the pressing part 95 is released again, so that the gear hinge 94 is re-held in a state where a part is placed in the first annular tooth groove 91 and the other part of the gear hinge 94 can be placed in the second annular tooth groove 62, and the housing 6 and the grip 9 are locked.

[0078] Furthermore, a fixing post 96 is formed on the pressing part 95. The fixing post 96 can be inserted into the gear hinge 94, and a second spring 97 is arranged outside the fixing post 96 to facilitate the reset of the pressing part 95.

[0079] As Figures 1-6 shown, it further includes a water storage tank 5 and a mixing joint 1. A connecting nozzle 11, a water inlet nozzle 12, and an air inlet nozzle 13 are formed on the mixing joint 1. The connecting nozzle 11 is used to connect with the nozzle assembly 4;

[0080] The water outlet pipe 22 of the water pump assembly 2 is connected to the water inlet nozzle 12. The water inlet pipe 21 of the water pump assembly 2 is connected to the water suction port 52 of the water storage tank 5 and can pump water from the water storage tank 5 and introduce the water into the mixing joint 1;

[0081] The air pump assembly 3 is connected to the air inlet nozzle 13, and the air pump assembly 3 can send air into the mixing joint 1;

[0082] The medium in the mixing joint 1 can be discharged through the nozzle assembly 4 after being mixed.

[0083] Furthermore, an air suction part 61 is arranged on the housing 6. The air inlet end of the air pump assembly 3 is connected to the air suction part 61 through an air suction pipe 33, enabling the air pump assembly 3 to smoothly suck the air outside the housing 6.

[0084] As Figures 1-6 shown, the air outlet end of the air pump assembly 3 is connected with an air outlet pipe one 31 and is connected to a pressure relief three-way joint 7 through the air outlet pipe one 31. An air outlet pipe two 32 is connected to the pressure relief three-way joint 7, and the air outlet pipe two 32 is connected to the air inlet nozzle 13, thereby realizing the connection of the air outlet end of the air pump assembly 3 with the mixing joint 1.

[0085] The pressure relief three-way joint 7 is also connected to a pressure relief valve 8 through a pressure relief pipe 34. The pressure relief valve 8 can ensure the constant air pressure inside the air outlet pipe one 31 and the air outlet pipe two 32. When the air pump assembly 3 is not turned on and the water pump assembly 2 is turned on, there is a certain air pressure inside the air outlet pipe one 31 and the air outlet pipe two 32, so as to prevent water from entering the air outlet pipe two 32.

[0086] Further, a pressure relief cavity 81 is formed inside the pressure relief valve 8;

[0087] One end of the pressure relief valve 8 is formed with a pressure relief valve interface 82, and a pressure relief channel 86 is formed inside the pressure relief valve interface 82. An air outlet hole 83 is opened at the other end of the machine housing 6; the pressure relief channel 86 and the air outlet hole 83 are communicated with the pressure relief cavity 81;

[0088] A first spring 85 and a steel ball 84 are arranged inside the pressure relief cavity 81, and the first spring 85 is used to push the steel ball 84 towards the pressure relief channel 86.

[0089] As Figures 1-6 shown, the nozzle assembly 4 includes:

[0090] A connector 44, inside which a water outlet channel 41 is formed. When the connector 44 is connected to the connecting nozzle 11, the water outlet channel 41 is aligned with the connecting nozzle 11;

[0091] A foaming net 42, which is detachably inserted into the water outlet channel 41;

[0092] A nozzle 43, which is detachably connected to one end of the connector 44.

[0093] By replacing the model of the nozzle 43, the watering can can spray water or foam of different shapes.

[0094] As a preferred embodiment, an air nozzle can also be connected to the end of the water outlet channel 41, so that when only the air pump assembly 3 of the watering can is turned on, the air nozzle can be used to inflate balloons, swimming rings or other items.

[0095] As Figures 1-6 shown, a kettle lid 51 is further arranged at the bottom end of the machine housing 6. The water storage tank 5 is detachably connected to the kettle lid 51. A water absorption port 52 is formed on the kettle lid 51, and the water absorption port 52 is used to be connected to the water pump assembly 2;

[0096] An end part inside the kettle lid 51 is provided with a water absorption joint, and a water extraction pipe member 53 is detachably arranged on the water absorption joint; when the water storage tank 5 is connected to the kettle lid 51, the water pump assembly 2 can extract the liquid at the bottom of the water storage tank 5 through the water extraction pipe member 53.

[0097] A battery assembly 92 is arranged inside the grip 9, and a charging port 93 is arranged at the end of the grip 9, so that the battery assembly 92 can be charged without disassembling the grip 9.

[0098] The above embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention should be covered within the protection scope of the present invention.
