Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a stepless speed-regulating high-pressure cleaner based on wireless communication. Background Technology

[0002] Handheld pressure washers are widely used in outdoor cleaning, vehicle washing, and yard maintenance due to their portability. Currently, the pressure adjustment methods of mainstream products fall into two categories: one involves switching pressure by changing nozzles of different orifice diameters, and the other involves adjusting the pressure level by pressing function buttons on the machine body. However, both methods have significant limitations: the former requires carrying multiple nozzles, and changing them necessitates interrupting the cleaning operation, making the disassembly and assembly process cumbersome and prone to losing parts; the latter is limited by the operating position, requiring users to frequently approach the machine to operate the buttons, especially when cleaning large areas or high / distant targets, where the back-and-forth movement not only reduces work efficiency but also increases operational inconvenience.

[0003] Furthermore, these types of products typically only have 2-3 pressure settings, making it impossible to precisely adjust the pressure according to the degree of soiling or the material being cleaned (such as car paint, glass, stone, etc.). This means they cannot accurately adjust the rotation speed for different cleaning needs (such as light dust removal, medium descaling, and heavy oil removal), resulting in either excessively high pressure that could damage the object being cleaned, or insufficient pressure that fails to achieve the desired cleaning effect. This also potentially wastes water and electricity, making it difficult to meet users' diverse needs for cleaning efficiency, effectiveness, and adaptability. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide a stepless speed-regulating high-pressure cleaner based on wireless communication, which solves the problems of inconvenient and inaccurate water pressure adjustment in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stepless speed-regulating high-pressure washer based on wireless communication includes a water gun and a complete machine. The water gun has a built-in wireless communication transmitter module and is connected to a smart terminal. The complete machine is equipped with a microcontroller, a drive circuit, a permanent magnet synchronous motor, and a wireless communication receiver. The water gun and the complete machine communicate wirelessly through the wireless communication transmitter module and the wireless communication receiver.

[0007] The wireless communication transmitting module is used to receive speed adjustment commands issued by the smart terminal and send digital signals. The wireless communication receiving device is used to receive digital signals and transmit them to the microcontroller. The microcontroller converts them into corresponding PWM signals. The drive circuit adjusts the voltage or current of the permanent magnet synchronous motor according to the PWM signals to achieve stepless speed regulation of the permanent magnet synchronous motor.

[0008] By adopting the above structural design, the water gun can receive speed adjustment commands from the smart terminal through a built-in wireless communication module. The speed adjustment commands are received and processed by the built-in wireless communication receiving device, microcontroller, and drive circuit, thereby enabling stepless speed regulation of the permanent magnet synchronous motor and realizing remote control and precise speed regulation of the permanent magnet synchronous motor.

[0009] As a further improvement, the power range of the permanent magnet synchronous motor is 2.5KW-5KW.

[0010] With the above structural design, the permanent magnet synchronous motor has the advantages of small size and strong output power, and its torque response is faster, which can quickly reach the rated voltage.

[0011] As a further improvement, the smart terminal includes a mobile phone or a dedicated remote control. The mobile phone can be equipped with an APP that allows for speed adjustment commands, and the dedicated remote control is equipped with a speed adjustment knob or a display slider.

[0012] The above structural design enables remote control of the permanent magnet synchronous motor speed of the entire machine, eliminating the need to approach the machine and adjust the speed using a knob on the machine, making it more convenient and efficient to use.

[0013] As a further improvement, the speed control knob can be mounted on the water gun.

[0014] As a further improvement, the wireless communication transmitting module and the wireless communication receiving device are one or a combination of Bluetooth module, WiFi module or ZigBee module.

[0015] As a further improvement, a water pipe is provided between the water gun and the whole machine, and the whole machine is connected to an external water source and an external power source. The water gun has a built-in battery to power the wireless communication transmission module.

[0017] 1. This utility model has a built-in wireless communication transmission module in the water gun. The whole machine is equipped with a microcontroller, drive circuit, permanent magnet synchronous motor and wireless communication receiving device. The whole machine and water gun can send speed adjustment commands through wireless signal transmission to the smart terminal, and adjust the speed of the permanent magnet synchronous motor through the microcontroller, thereby realizing remote adjustment of the water gun pressure. There is no need to adjust the pressure on the whole machine, which improves the convenience of using the cleaning machine.

[0018] 2. This utility model uses a permanent magnet synchronous motor drive, and after receiving wireless signals through a wireless communication receiving device, it is parsed into raw data that can be recognized by a microcontroller. The microcontroller converts the data into a corresponding PWM signal and transmits the PWM signal to the drive circuit. The drive circuit adjusts the voltage or current of the permanent magnet synchronous motor according to the PWM signal, thereby realizing stepless speed change of the permanent magnet synchronous motor and precise adjustment, so that the cleaning machine can achieve the best cleaning effect.

[0019] 3. The permanent magnet synchronous motor used in this invention is small in size, has high power density, low noise, and energy consumption is reduced by 10%-20% compared to asynchronous motors. Attached Figure Description

[0022] Please see Figure 1 A continuously variable speed high-pressure washer based on wireless communication includes a water gun and a main unit. A water pipe connects the water gun and the main unit, and the main unit is connected to an external water source and an external power supply. The water gun has a built-in wireless communication transmitter module, which is powered by a built-in battery. The water gun is connected to a smart terminal, which may be a mobile phone or a dedicated remote control. The mobile phone can install an app with adjustable speed commands, and the dedicated remote control has a speed control knob or a display slider. The main unit includes a microcontroller, a drive circuit, a permanent magnet synchronous motor, and a wireless communication receiver. Wireless communication between the water gun and the main unit is achieved through the wireless communication transmitter module and the wireless communication receiver.

[0023] The intelligent terminal issues a speed adjustment command, which is encapsulated into a digital command through a wireless communication transmission module. The digital command is then transmitted wirelessly to the entire machine. The wireless communication receiving device receives the wireless signal and parses it into raw data that the microcontroller can recognize. The microcontroller converts the data into a corresponding PWM signal and transmits the PWM signal to the drive circuit. The drive circuit adjusts the voltage or current of the permanent magnet synchronous motor according to the PWM signal, thereby adjusting the permanent magnet synchronous motor to achieve stepless speed regulation and ultimately achieve precise adjustment of the water gun pressure.

[0024] In this embodiment, the permanent magnet synchronous motor has a power range of 2.5KW-5KW. Compared with the asynchronous motors used in existing cleaning machines, the permanent magnet synchronous motor is smaller in size, has stronger power, faster torque response during operation, and can quickly reach the rated pressure. At the same time, it has lower energy consumption and lower noise.
