DETAILED DESCRIPTION

[0036] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the hand disinfector or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] The hand disinfection machine in the prior art can only spray out the required amount by manually adjusting the gear. The spray area of ​​the disinfectant spray is generally fixed. The hand sizes of different people are different. Spraying too much will cause a waste of disinfectant, and spraying too little will make the hands inadequately disinfected. The hand disinfection machine provided by the present invention does not need to manually adjust the gear. Just stretch out your hand to automatically adjust the gear of the appropriate spray according to the size of the hand and adjust the spray size; the spray area is automatically adjusted according to the position of the hand, and there is no need to put the hand in the middle of the fixed disinfection area, which improves the user experience.

[0040] Figure 1 The flowchart of a hand disinfection machine control method is schematically shown. Figure 1 As shown, a hand disinfection machine control method provided by the present invention comprises the following steps:

[0041] S10, obtaining hand signals detected in real time;

[0042] Specifically, a detection component 4 is provided in the hand disinfection machine, and the detection component 4 detects a hand signal to execute step S20, and the hand signal means that the hand appears above the detection component 4, and the shadow of the hand partially or completely covers the detection area, that is, the detection component 4 obtains the hand signal detected in real time. The hand signal may include the size and shape of the hand, and the hand disinfection is performed according to the detected hand size and / or hand shape.

[0043] Of course, the hand disinfection machine is not limited to hand disinfection, but can also disinfect any object that needs to be disinfected. The specific disinfection objects are not specifically limited here and can be set according to actual needs.

[0044] Furthermore, the hand signal is obtained, mainly the capacitance value change detected in the sensing area is obtained, and the hand size is judged according to the capacitance value change area. By detecting the capacitance value change of the hand, the hand size is judged, and the disinfection area of ​​the disinfection spray and the adjustment of the gear are further determined according to the hand size.

[0045] Of course, the form of obtaining hand signals is not limited to judging the hand size based on the detected capacitance value change, but can also be detected according to other judgment methods. Again, the hand size detection method is only detected in the form of capacitance, and other forms of detection methods can be set according to specific circumstances.

[0046] S20, determining target disinfection parameters that match the hand signal;

[0047] Specifically, the target disinfection parameter is the spraying disinfection spray gear, and the size of the disinfection area is determined according to the size of the hand, and then the disinfection spray gear is determined. The specific area of ​​the disinfection is determined according to the size of the hand. In the prior art, the hand can only be disinfected if it reaches the designated area. In the hand disinfector provided in this embodiment, the hand can be extended to any position at will. The detection component 4 determines the area of ​​the disinfection area according to the detected hand area, and determines the specific disinfection spray gear according to the area of ​​the disinfection area.

[0048] S30: Spray disinfectant spray on hands to disinfect according to the acquired target disinfection parameters.

[0049] The target disinfection parameter matching the hand signal is searched according to a preset correspondence table, wherein the correspondence table includes the correspondence between the hand size and the target disinfection parameter. The duty cycle is adjusted according to the area of ​​the area where the capacitance value changes, thereby controlling the vibration frequency of the disinfection component.

[0050] The control method of the hand disinfector provided in this embodiment is that a plurality of metal plates are provided at the bottom of the hand disinfector to form a capacitor plate 41 matrix. When the hand is extended into the disinfection area in the hand disinfector, the capacitance value of the area corresponding to the hand in the capacitor plate 41 matrix changes. The capacitance sensor detects and collects the signal of the capacitor plate 41 and transmits it to the controller. The controller detects the area of ​​the capacitor plate 41 corresponding to the capacitance value change, automatically adjusts the spray gear according to the size of the capacitor plate 41 area, and adjusts the spray spray area of ​​the disinfectant according to the hand position, thereby realizing the ability to detect the size and position of the hand to automatically control the spray gear and spray area of ​​the disinfectant, thereby improving the user experience.

[0051] like Figure 2 As shown, the implementation of the control method of the hand disinfection machine of the present invention is explained below through the second embodiment.

[0052] The embodiment provided by the present invention is as follows: after the hand disinfection machine is started, it starts to work, the detection component 4 detects a hand signal in the sensing area, and determines whether the capacitance value changes according to the hand signal. If the capacitance value changes, it is determined whether the hand goes deep into the sensing area of ​​the hand disinfection machine or the hand extends out of the sensing area of ​​the hand disinfection machine. The above judgment condition is detected according to the degree of change of the capacitance value. If the capacitance value increases, it is determined that the hand goes deep into the sensing area for disinfection; if the capacitance value decreases, it is determined that the hand extends out of the sensing area.

[0053] Furthermore, if it is determined that the hand has entered the sensing area of ​​the hand disinfection machine, the controller receives the signal to determine the capacitor plate area where the capacitance value increases, and detects the position and size of the hand according to the capacitor plate 41 area, that is, the spraying area of ​​the disinfectant spray and the spray spraying gear. The spray assembly 3 and the spray gear of the nozzle 35 are rotated according to the position and size of the hand, so that the nozzle 35 sprays the disinfectant spray to disinfect the hand.

[0054] If it is detected that the hand extends out of the sensing area of ​​the hand disinfector, the capacitance of the capacitor plate 41 is restored to the initial setting capacitance, and the controller controls the nozzle 35 to stop working and controls the capacitor plate 41 to re-detect the capacitance change of the plate.

[0055] The present invention provides a control method for a hand disinfection machine. When the hand disinfection machine starts working, the capacitance sensor detects the change of the capacitance of the capacitance plate 41. If the capacitance of the capacitance plate 41 does not change, the capacitance sensor is always detecting the capacitance of the capacitance plate 41.

[0056] When the hand is inserted into the disinfection area of ​​the hand disinfector, the capacitance of the capacitor plate 41 under the hand area changes. The capacitance sensor detects that the capacitance of part of the capacitor plate 41 area increases and collects and transmits it to the controller. The controller receives the signal and determines the area of ​​the capacitor plate 41 where the capacitance increases. The hand position and hand size can be detected based on the area of ​​the capacitor plate 41 where the capacitance increases. Then, the spray area is obtained by automatically adjusting the angle of the nozzle 35 of the rotating device according to the position of the hand; the spray gear is automatically adjusted according to the size of the hand.

[0057] When the hand is extended out of the disinfection area of ​​the hand disinfector, the capacitive sensor detects that the capacitance of the capacitor plate 41 is restored to a value close to the original value and collects and transmits it to the controller. The controller receives this signal and determines that there is no object above the capacitor plate 41, and determines that the hand has left the hand disinfector. The controller receives and sends a signal to control the spray head to stop working and control the spray assembly 3 to return to its original position. The capacitive sensor continues to detect the change in the capacitance of the capacitor plate 41, and the hand disinfector enters the next round of work.

[0058] Preferably, when the area of ​​the capacitor plate 41 with increased capacitance is 130 square millimeters, the PWM duty cycle is 40%; when the area is 150 square millimeters, the PWM duty cycle is 50%; when the area is 170 square millimeters, the PWM duty cycle is 60%. Of course, the corresponding relationship between the area of ​​the capacitor plate 41 with increased capacitance and the duty cycle can be set according to the user's own needs, and only one specific embodiment is used here for explanation.

[0059] For the method embodiments, for the sake of simplicity, they are all described as a series of action combinations, but those skilled in the art should know that the embodiments of the present invention are not limited by the order of the actions described, because according to the embodiments of the present invention, some steps can be performed in other orders or simultaneously.

The fixing plate is fixedly connected to the inner wall of the shell 5. By fixing the connecting member 31 in the shell 5, the setting position of the spray assembly 3 is determined, and then the disinfection range is determined.

[0064] Furthermore, the driving structure includes a first stepper motor and a second stepper motor. The first stepper motor is arranged in the accommodating space formed by the connecting member 31 and the inner wall of the shell 5, and the second stepper motor is arranged on the bracket 34, so that the first stepper motor drives the bracket 34 to move in the first direction on the horizontal plane, and the second stepper motor drives the bracket 34 to move in the second direction on the horizontal plane.

[0066] Furthermore, an adapter is provided at the bottom of the connecting member 31, and the adapter can be set as a connecting shaft, which connects the connecting member 31 and the second stepper motor, so that the first stepper motor and the second stepper motor jointly control the rotation of the nozzle 35, thereby further accurately determining the area of ​​the disinfection area.
