[0049] In this embodiment, the power supply female port 236 of the power control system 23 is arranged on the surface of the solar panel fixing frame 22, and the power supply male port 14 of the spray pot barrel body 1 is arranged in the groove body 101, and the power supply male port 14 is electrically connected to the power supply female port 236; in this embodiment, the power supply male port 14 is a DC005 male port, which has a reserved long wire for connecting with the power supply female port 236, and the power supply female port 236 is a DC005 female port, and the two cooperate to realize the connection between the solar component 2 and the sprayer to supply power to the sprayer.

[0050] The solar panel fixing frame 22 includes an upper cover 221 and a lower cover 222, which are fixed as a whole by screws. The solar panel 21 is welded and fixed in a first chamber 223 on the upper surface of the upper cover 221. The power control system 23 is positioned in a second chamber 224 formed between the upper cover 221 and the lower cover 222. The second chamber 224 includes a middle chamber and two side chambers.

[0051] The connecting wire of the solar panel 21 passes through the upper cover 221 and is electrically connected to the power control system 23. The power supply female port 236 of the power control system 23 passes through the socket 2221 opened on the side of the upper cover 221 and / or the lower cover 222 and is electrically connected to the power supply male port 14 of the spray pot barrel body 1. In this embodiment, the socket 2221 is arranged on the side of the upper cover 221 and the lower cover 222.

[0052] The power control system 23 includes a control circuit board 231 and a rechargeable battery 232, which are positioned and connected in the second chamber 224. Specifically, the control circuit board 231 is positioned and clamped in the middle chamber and fixed by screws, and the rechargeable battery 232 is positioned and clamped in the side chamber. The rechargeable battery 232 can use 1-2 18650 lithium batteries; the connecting wire of the solar panel 21 passes through the upper cover 221 and is electrically connected to the control circuit board 231, specifically, it is welded; the control circuit board 231 is electrically connected to the rechargeable battery 232; in this way, after the solar panel 21 converts the collected solar energy into electrical energy, the electrical energy can be stored in the rechargeable battery 232 through the control circuit board 231.

[0053] In this embodiment, the power control system 23 also includes a discharge socket 233 and a charging socket 234; the discharge socket 233 and the charging socket 234 are connected to the control circuit board 231. When the power in the rechargeable battery is high, the discharge socket 233 can be used to charge the user's mobile phone or tablet in an emergency, which has a wider range of uses; the discharge socket 233 and the charging socket 234 pass through the lower surface of the lower cover 222 and waterproof plugs 235 are clamped in the two holes. The waterproof plugs 235 in the two holes are integrally arranged. When the two sockets 2221 are in use, the waterproof plugs 235 are unplugged, and when not in use, the waterproof plugs 235 are installed to prevent liquid from entering the two sockets and causing a short circuit.

[0054] When the sprayer is out of power, it can be charged by connecting to an external power source through the charging socket 234. The charging socket 234 can adopt a type-C interface and can be matched with a type-C cable.

[0055] The discharge socket 233 may be a USB interface, which is used to use the discharge socket 233 to charge the user's mobile phone or tablet in an emergency.

[0056] One side edge of the solar panel fixing frame 22 is movably engaged with the first slot 102 in the slot body 101 via a locking rib 225 ; the other side edge of the solar panel fixing frame 22 is locked with the locking assembly 103 in the slot body 101 via a second locking slot 226 .

[0057] See attached Figure 8 , wherein the lock assembly 103 can adopt the lock structure used in the pop-up cup cover, which includes an unlocking button 1031 and a compression spring 1032. When the solar module 2 is locked in the slot 101, the buckle position of the unlocking button 1031 is embedded in the second card slot 226 under the action of the compression spring 1032. When the solar module 2 is unlocked, the unlocking button 1031 is pressed, which compresses the compression spring 1032, and the buckle position is separated from the second card slot 226, and the solar module 2 can be disassembled at this time.

[0058] In order to enable the solar component 2 to automatically pop out when unlocked and to facilitate taking out, a rebound compression spring 104 can be vertically arranged in the groove body 101, and the top of the rebound compression spring 104 abuts against the lower surface of the solar panel fixing frame 22, that is, abuts against the lower surface of the lower cover 222; when the solar component 2 is locked, the rebound compression spring 104 is compressed by the lower cover 222, and when unlocked, the rebound compression spring 104 resets and pushes the lower cover 222 to bounce the entire solar component 2 out of the groove body 101, thereby facilitating the removal of the solar component 2.

[0059] When the entire sprayer is assembled, the solar panel 21 can be welded in the first chamber 223, and the power control system 23 can be fixed in the second chamber 224. At this time, the solar panel 21 seals the first chamber 223, and the lower cover 222 seals the second chamber 224, forming a solar panel assembly 2 as a whole.

[0060] Then install the solar module 2 in the slot 101. Before installation, the power supply female port 236 and the power supply male port 14 must be plugged together to form a passage, and then the locking rib 225 must be engaged with the first slot 102. After engagement, the solar module 2 can drive the locking rib 225 to rotate in the first slot 102. When it rotates to the point where the second slot 226 corresponds to the locking assembly 103, press the solar module 2 downward, and its second slot 226 is locked with the locking assembly 103 to complete the assembly of the solar module 2.

[0061] In this embodiment, the outer contour of the spray gun 13 is clamped on the handle 12. Specifically, a placement groove 121 is provided on the upper surface of the handle 12 along its length direction, and the hand-held part of the spray gun 13 is clamped in the placement groove 121. In addition, a plurality of retaining ribs 122 are arranged at intervals in the placement groove 121 along the groove length direction, which can stably support the spray gun 13 horizontally and prevent the hand-held part from easily falling off from the placement groove 121. After being stored, the entire spray pot barrel body 1 has a neat and beautiful appearance, and the placement space is reduced.

[0062] See attached Figure 10-12 The spray gun 13 includes a handle 131 having a central longitudinal axis and an outer contour configured to be held by a user, so that the spray gun 13 can be easily held by one hand to operate the spray gun 13.

[0063] The handle 131 is disposed on the spray gun 13, and the handle 131 includes a right handle cover 131a and a left handle cover 131b, and the right handle cover 131a and the left handle cover 131b are aligned and buckled along the central longitudinal axis to form a receiving cavity, and the electric wire 135 and the water pipe 136 are arranged in the receiving cavity. Since the handle 131 has a stable spatial structure inside, the distance between the electric wire 135 and the water pipe 136 is increased to avoid contact between the water and electricity, thereby providing safety performance.

[0064] The handle 131 is provided with an electric wire 135 and a water pipe 136 that runs through the front and rear ends of the handle 131, and the electric wire 135 and the water pipe 136 are spaced and insulated. The electric wire 135 and the water pipe 136 can be reliably insulated by ensuring a sufficient spacing distance; the electric wire 135 and the water pipe 136 can be reliably insulated by providing an insulating structure such as a rubber pad (not shown in the figure). The water circuit and the circuit can be effectively isolated by maintaining a certain distance between the electric wire and the water pipe in the handle. When the water circuit is kept in a normally open state, the insulating safety design formed by the isolation can avoid the occurrence of safety accidents. Therefore, this case can realize the control of both water and electricity by a single switch for easy one-handed operation while ensuring the safety of operation.

[0065] The handle 131 is provided with a button switch 133, and the button switch 133 acts on a button circuit board 134 in the handle 131. The button circuit board 134 is electrically connected to the first end of the wire 135, and the second end of the wire 135 is electrically connected to the working circuit of an air pump. The air pump is arranged in the barrel body 11 as shown. When the button switch 133 is pressed, the air pump can be controlled to start or stop working.

[0066] The first end of the water pipe 136 is connected to a spray rod 138, and the second end of the water pipe 136 is connected to the barrel body.

[0067] Among them, the wire 135 and the water pipe 136 are extended through the through hole 132 opened at the rear end of the handle 131, and the first end of the wire 135 is electrically connected to the key switch 133 through a key circuit board 134, and the second end of the wire 135 is electrically connected to the working circuit of the air pump (for example: the host PCB).

[0068] The spray rod 138 of this embodiment is connected to the head of the handle 131 , the first end of the spray rod 138 is connected to the handle 131 via a spray rod joint 137 , and the second end of the spray rod 138 is sleeved with a spray head 139 .

[0069] The nozzle 139 of this embodiment can be used to selectively discharge a pressurized fluid, or to jointly discharge a gas-liquid mixture or a solid-liquid mixture consisting of a pressurized fluid and at least one additive; wherein the additive is selected from the following group, which includes: solid particles, fire extinguishing powder, fire extinguishing additives, foaming agents, dry ice and detergents, etc.

[0070] In this embodiment, during the liquid spraying operation, when the hand presses the key switch 133, the key switch 133 triggers the key circuit board 134, and the key circuit board 134 transmits the electrical signal to the working circuit of the air pump through the wire 135, controls the air pump to start the operation, triggers the liquid inside the spray pot barrel body 1 where the air pump is located to be transported along the water pipe 6 to the spray gun 13, and the liquid is pumped to the spray rod 138, and finally sprayed out by the spray head 139, and the handle 131 is operated by one button, and water and electricity are turned on at the same time, so as to be controlled by one hand;

[0071] When the hand is away from the key switch, the key switch 133 is disconnected, and the key switch 133 is separated from the key circuit board 134, interrupting the electrical signal transmitted from the key circuit board 134 to the working circuit of the air pump through the wire 135, thereby turning off the air pump and stopping the liquid inside the spray pot barrel body 1 where the air pump is located from being transported to the spray gun 13 along the water pipe 136, thereby achieving simultaneous cutting off of circuit control and water circuit control.

[0072] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
