Detailed Description
The following detailed description of the preferred embodiments of the present application, taken in conjunction with the accompanying drawings, will make the advantages and features of the present application more readily appreciated by those skilled in the art, and thus will more clearly define the scope of the invention.
In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; may be mechanically connected, may be electrically connected or may be in communication with each other; they may be directly connected or indirectly connected through intervening media, or may be connected through the use of two elements or the interaction of two elements. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as the case may be.
Referring to fig. 1, a structure of a showerhead control assembly according to an embodiment of the present application is shown.
As shown in fig. 1, the spray head control assembly may be a spray head control assembly of a sprayer or other water/steam spraying device, and includes a spray head 1, a pipe 2, a pump body 3, and a control circuit 4.
The spray head 1, which is used for spraying gas or liquid in the pipe 2, can be connected with a water tank 6 or other storage device of the equipment through the pipe 2 to obtain corresponding liquid or gas.
In one embodiment, the spray head control assembly further comprises a spray head 1 switch, and the spray head 1 switch controls the spray head 1 to be opened and closed. The switch of the spray head 1 can actively control the opening or closing of the spray head 1, so that a physical control mode of the use state of the spray head 1 is provided, and the control effect of the spray head control assembly is improved.
The pump body 3, which is disposed in the pipe 2, includes a pressure switch 31 and a motor 32 for delivering gas or liquid to be sprayed to the nozzle 1. The pressure switch 31 detects the pressure of the gas or liquid and performs opening and closing control according to the pressure. The motor 32 can be driven by the control circuit 4 to operate the pump body 3 and push the liquid or gas in the pipe 2. The pressure switch 31 can detect the pressure of gas or liquid in the pipeline 2 through devices such as a sensor, when the pressure is greater than a certain preset value, the line connection in series with the pressure switch 31 is disconnected, and when the pressure is less than or equal to the certain preset value, the line connection is closed, so that the line is conducted. By detecting the opening or the disconnection of the pressure switch 31 through the control circuit 4, the pressure condition of the liquid or the gas in the pipeline 2 can be determined, and therefore whether the spray head 1 is in a closed or opened state can be judged.
The control circuit 4 includes a controller 41, and the controller 41 is electrically connected to the pressure switch 31 and the motor 32 of the pump body 3. The controller 41 may be an MCU or other logic controller 41 that can execute a predetermined program.
The motor 32 is controlled by a controller 41 to operate, and the controller 41 detects the pressure switch 31 of the pump body 3 to determine whether the spray head 1 is closed or blocked, so as to control the motor 32 to be turned on or off. Specifically, when the pressure switch 31 is turned off because the detected pressure is greater than the preset value, the controller 41 turns off the pump body 3; when the pressure switch 31 is closed because the detected pressure is smaller than the preset value, the controller 41 turns on the pump body 3.
It can be understood that the preset value can be set according to a pressure value which is actually possible to reach after the spray head 1 is closed, and the value of the specific pressure value is not limited in the embodiment of the application.
In one embodiment, the pressure switch 31 is turned off when the detected pressure is greater than a predetermined value, and the motor 32 of the pump body 3 is powered on in a delayed manner. When the pressure switch 31 is just turned off, the internal pressure of the pipeline 2 is at a critical point, and the pressure switch 31 is easily turned off again because the pump body 3 falls back to a preset pressure value after stopping. After the motor 32 of the pump body 3 is powered in a delayed manner, the pump body 3 continues to supply water for a period of time, so that the pressure switch 31 can be stably switched off after being switched off. In a certain setting, the delay may be 30 seconds. Of course, the specific time length of the delay can be determined according to actual conditions.
The motor 32 of the pump body 3 is connected in series with the pressure switch 31, and is connected in series between the positive electrode of the driving end of the motor 32 and the positive electrode of the power supply 5. When the pressure switch 31 is closed, the power supply 5 can supply power to the motor 32 through the pressure switch 31, and when the pressure switch 31 is opened, the motor 32 is still controlled by the controller 41, so that the control effects of delaying the operation of the motor 32 and the like can be realized. The motor 32 is connected in series with the pressure switch 31, so that the control effect of the controller 41 on the motor 32 can be improved, and the working state of the pump body 3 can be controlled more accurately.
In another embodiment, the controller 41 can, in addition to turning off the motor 32 of the pump body 3, enable the motor 32 and related components to enter a standby state, and continuously monitor the opening and closing of the pressure switch 31, so as to reactivate after the pressure switch 31 is closed, and return to a normal operating state. In this way, the switching between the standby state and the operating state of the head control unit can be controlled by controlling the opening and closing of the head 1.
The power source 5 is electrically connected to the controller 41 and the pump body 3. The power supply 5 may be a battery pack built in the device, or may be an externally input power supply 5, and the specific power supply 5 may be determined according to actual requirements.
In the working process, the spray head control assembly is in normal work, the water flow of the pipeline 2 is sprayed out from the spray head 1, the internal pressure of the pipeline 2 is in a normal pressure value, and the pressure switch 31 is in a closed state at the moment. When the spray head 1 is closed or blocked, the pump body 3 continues to operate, with an increasing pressure inside the pipe 2. When the internal pressure of the pipeline 2 is greater than the preset value of the pressure switch 31, the pressure switch 31 is automatically turned off, and at this time, the controller 41 of the control circuit 4 can turn off the motor 32 of the pump body 3 or enter a standby state according to the turn-off condition of the pressure switch 31, so that the increase of the internal pressure of the pipeline 2 due to the continuous work of the motor 32 is avoided, and the internal damage is avoided.
When the spray head 1 of the spray head control assembly is opened again or is in a blockage-releasing state, the pressure in the pipeline 2 is restored to a normal state after the liquid or the gas in the pipeline 2 is released through the spray head 1, and then the pressure switch 31 is closed. When the pressure switch 31 is closed, the controller 41 detects that the pressure switch 31 is in a closed state, and then activates the control circuit 4, and outputs a soft start voltage to the motor 32 of the pump body 3 through the control circuit 4, so that the motor 32 can work normally.
By last knowing, among the shower nozzle control assembly of this application, through set up pressure switch in the pump body, utilize pressure switch to monitor the pressure in the pipeline to make control circuit can come the work of more accurate control pump body according to the pressure condition in the pipeline, improve the control accuracy to the pump body.

The sampling terminal Detecter can detect the current voltage or current condition of the motor M1, thereby determining the current working state of the motor M1.
In one embodiment, in order to control the operation of the motor M1, a MOS switch is further disposed between the negative electrode of the motor M1 and the negative electrode P-of the power supply, and the MOS switch is connected to the driving terminal of the second motor M1 of the controller MCU so as to be controlled by the controller MCU to open and close. Specifically, the MOS switch may implement control of the motor M1 through PWM control.
In another embodiment, a protection module a1 is further disposed between the controller MCU and the negative electrode P-of the power supply, and the protection module a1 may monitor a current value/voltage value of the motor through a combination of an operational amplifier and a sampling resistor RES to determine whether an overcurrent phenomenon such as a short circuit of the motor M1 occurs, thereby protecting the safety of the whole product.
In addition, the protection module a1 can also cut off the power supply and control of the motor M1 by monitoring the temperature of the MOS switch when the temperature of the MOS switch reaches a certain value, thereby avoiding damage caused by overheating of the MOS switch.
Furthermore, the spray head control assembly may be provided with a light set, so that when the MOS switch is overheated or the current of the motor M1 is overcurrent, the protection module a1 may perform a flashing light prompt through the light set to warn the user.

In one embodiment, for more precise control, a range switch SW-DPDT having at least two ranges is provided between the positive pole P + of the power source and the controller MCU, and the range switch SW-DPDT controls the controller MCU to perform range control on the operating voltage of the motor M1.
Specifically, the position switch SW-DPDT may be provided with two different positions, namely, a high position and a low position, in an embodiment, when the position of the position switch SW-DPDT is the high position, the control board controls the MOS switch through PWM and samples the voltage across the motor M1 through the sampling terminal Detecter, and the voltage across the motor M1 is constant at 12V.

Through gear switch SW-DPDT and sampling end Detecter to motor M1's voltage control for the shower nozzle control assembly can realize the control to more accurate voltage of motor M1 and operating condition, thereby further improves the control accuracy of the pump body. Of course, the actual operating voltage of the motor M1 needs to be determined according to the model of the motor M1 and the power supply requirement, which is not limited in this application.
Further, the gear switch SW-DPDT is a self-locking switch, and may be a type of self-locking switch such as a stepless speed regulation switch, a boat-shaped switch, and the like. Meanwhile, the number of the switch paths is not limited by the gear switch SW-DPDT so as to meet the control requirements of users on different working gears of the motor M1.
