Directional terms as referred to in the following examples, for example: up, down, left, right, front or rear, etc., are simply directions with reference to the drawings. Accordingly, the directional terminology used is intended to be in the nature of words of description rather than of limitation.

Referring to fig. 1 to 7, which are a perspective view, an exploded view, a side view of an internal structure, a perspective view of an internal structure, a side view, a partially enlarged view of a nozzle portion, and an exploded view of a nozzle portion according to an embodiment of the present disclosure, a wireless sterilization device 10 of the present embodiment mainly includes a housing 11, and further includes a nozzle portion 12, a first control circuit 13, an air intake motor 14, a second control circuit 15, a nozzle unit 16, a liquid storage unit 17, an infusion tube 18, and a power supply unit, all of which are disposed inside the housing 11, wherein functions or connection relationships of the components are described as follows:

one end of the housing 11 is provided with a handle hole 111, the other end is provided with a through opening 112, the through opening 112 is sleeved with the inherent spraying end portion 12, the handle hole 111 can be used for a user to hold the wireless sterilization device 10 with one hand, the wireless sterilization device has the beneficial effects of convenient carrying and easy holding, and as can be seen from the figure, the housing 11 mainly comprises an upper cover and a lower cover which is in a pulling and disassembling type.

The first control circuit 13 is electrically connected to the intake motor 14, and the first control circuit 13 is coupled to the second control circuit 15, the intake motor 14 is mainly controlled by the first control circuit 13, and the driving of the intake motor 14 and the driving of the intake motor are otherwise indirectly controlled by the second control circuit 15, but the present application proposes two control circuits as an example, which is to avoid the problem that the higher power components are concentrated on the same circuit board (PCB) to cause overheating of the motor, and when the motor is overheated, the circuit board may be affected in a linked manner to cause overheating of the circuit board, so the control circuit (control program) belonging to the intake motor 14 is integrated on the first control circuit 13.

A first pipe end of the nozzle unit 16 is connected to the nozzle portion 12, a second pipe end of the nozzle unit 16 is connected to an air outlet pipe 141 of the air inlet motor 14, a third pipe end of the nozzle unit 16 is connected to the liquid storage unit 17 in a downward sleeved manner, and an infusion tube 18 extends upward from the liquid storage unit 17 to penetrate into the nozzle unit 16 (the infusion tube 18 extends into the nozzle unit 16 is not shown), so that the nozzle portion 12, the air outlet pipe 141 and the inner space of the liquid storage unit 17 can be communicated through pipe openings at two ends of the infusion tube 18.

As shown in fig. 7, the nozzle portion 12 has a nozzle structure 121, the nozzle structure 121 is composed of a hollow fin wheel 123 sleeved in a sleeve 122, a threaded portion 124 protruding from the sleeve 122, and a water guide tube seat 125 connected to the threaded portion 124, a water guide connection tube 126 is formed at the other end of the water guide tube seat 125, the water guide connection tube 126 is used for connecting the infusion tube 18, one end of the sleeve 122 is sleeved and fixed at the first tube end of the nozzle unit 16, each fin 1231 of the fin wheel 123 is partially exposed at the other end of the sleeve 122 (as shown in the second nozzle end S2 of fig. 6), and preferably, the nozzle structure 121 further includes a wheel back ring plate 127 overlapped at the other end of the fin wheel 123.

As shown in fig. 2 to 4, the air intake motor 14 is used to promote the flow of air, after the air intake motor 14 is driven, the air is blown into the nozzle unit 16, so that siphoning occurs at the ends of the nozzle unit 16 to generate an airflow pressure difference, and a sterilization liquid in the liquid storage unit 17 is sucked into the water guide connection pipe 126 and pushed to a first nozzle end S1 of the nozzle structure 121 located outside the nozzle, and the air is guided to a second nozzle end S2 of the nozzle structure 121 located outside the nozzle by a flow channel space formed by the fins 1231 of the fin wheel 123, as shown in fig. 6, the second nozzle end S2 may be a gap partially exposed from the fins 1231 of the fin wheel 123 of the sleeve 1211 (the gap extends from the flow channel space between the two fins), so that the air and the sterilization liquid are merged outside the nozzle, and the air and the sterilization liquid are generated by the friction force, Preferably, when the air intake motor 14 of the wireless sterilization device 10 is actuated, high-pressure jet (air) is firstly ejected from the first ejection end S1, and the sterilization liquid is then ejected from the second ejection end S2 (i.e., first air is ejected and then water is discharged), and the sterilization liquid is broken up by high-speed air, so that the particle size of the sterilization liquid becomes smaller, which can cause the ejection of the sterilization liquid with smaller particle size, so that the contact area of the sterilization liquid is larger, and the reaction efficiency after the sterilization liquid is sprayed becomes faster, meaning that the spray sterilization efficiency is more careful than the prior art sprayer, and while taking the spraying effect into consideration, the consumption of the sterilization liquid can be saved, and the sterilization liquid can be fully used.

As shown in fig. 1 and 5, preferably, a water level window W for viewing the sterilized water level in the liquid storage unit 17 may be opened at a position of the side surface of the housing 11 relative to the liquid storage unit 17, so that a user can conveniently determine whether to supplement the sterilized water or to replace another bottle of the liquid storage unit 17.

As shown in fig. 2 to 4, a sound-absorbing sponge (not shown) may be disposed inside the housing 11 and near the intake motor 14 for reducing noise generated by the intake motor 14 during operation.

Preferably, a battery chamber structure 191 for placing the power supply unit may be formed in the interior of the housing 11 at a position corresponding to the power supply unit, and a second battery chamber structure 192 is disposed adjacent to the battery chamber structure 191, wherein the power supply unit may be, for example, one or more lithium batteries, and if the power supply unit is composed of two lithium batteries, the two battery chamber structures (191, 192) may respectively place the lithium batteries of the power supply unit, but not limited thereto.
