Description

Technical Field

[0001] The utility model relates to the technical field of cleaning machines, in particular to a multiple pressure-controlled visual cleaning machine based on a three-voice coil linear motor. Background Art

[0002] A cleaning machine is an industrial cleaning equipment that uses water pressure to wash the surface of an object. Current cleaning machines do not have a distance measurement function, and it is difficult to control the cleaning impact force on the cleaning object during use. When the cleaning impact force is too large, it is easy to cause damage to the cleaning object. Therefore, we proposed a multi-pressure controlled visual cleaning machine based on a three-voice coil linear motor to solve the above problem. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example

[0023] like Figure 1-4 As shown, a multiple pressure-controlled visual cleaning machine based on a three-voice coil linear motor proposed in an embodiment of the utility model includes a cleaning machine body 1, a three-voice coil linear motor body 2 is installed inside the cleaning machine body 1, a cavity is arranged inside the cleaning machine body 1, a mover assembly is arranged in the cavity, the output shaft of the three-voice coil linear motor body 2 is fixedly connected to the mover assembly, an overflow valve and a cleaning bottle assembly 3 are installed at one end of the cleaning machine body 1, the overflow valve and the cleaning bottle assembly 3 are connected to the cavity, a nozzle 4 is installed at the liquid spraying end of the cleaning machine body 1, a small water outlet 5 and a large water outlet 6 are opened on the nozzle 4, an infrared rangefinder modulated light transmitting unit and a receiving unit 7 are installed on the nozzle 4, a counting display unit and a logic control unit 8 are installed on the cleaning machine body 1, a motor power adjustment button 9 is arranged on the cleaning machine body 1, and a relay 10, a motor battery 11, and an infrared rangefinder battery 12 are installed in the cleaning machine body 1.

[0024] When the three-voice coil linear motor body 2 is powered on, an alternating current flows into the coil, causing the current to change at a fixed frequency, so that the coil generates two alternating magnetic fields that change from mutual repulsion to mutual attraction, and reciprocate, causing the mover assembly to generate an alternating axial force, pushing the mover assembly to perform linear reciprocating motion. Therefore, a magnetic field oriented control method is adopted to control the current of the three-voice coil linear motor body 2 through the motor power adjustment button 9, thereby changing the direction and size of the magnetic field of the three-voice coil linear motor body 2, so as to achieve the purpose of controlling the movement speed of the output shaft of the three-voice coil linear motor body 2. It has the advantages of fast response speed, high control accuracy, and multiple gears. The overflow valve and the overflow valve in the cleaning bottle assembly 3 are safety protections for the pressure of the output chamber. When the pressure in the output chamber is too high or the adjustment button fails, the overflow valve can be opened to release the pressure. The cleaning fluid in the cleaning bottle is forced into the nozzle 4 and sprayed out along with the water flow through the effect that the atmospheric pressure is higher than the pressure in the chamber, so that the purpose of manually applying the cleaning fluid is achieved, which greatly saves time. In addition, the non-diffusion principle of infrared propagation is used in this application, because the refractive index of infrared rays is very small when passing through other substances, and the propagation of infrared rays takes time. When the infrared ray is emitted from the modulated light emitting unit and receiving unit 7 of the infrared rangefinder and hits the reflector, it is reflected back and received by the rangefinder, and then the distance can be calculated according to the time from the emission to the reception of the infrared ray and the propagation speed of the infrared ray. Then the distance is displayed according to the logical operation of the counting display unit and the logic control unit 8, and it is judged whether the cleaning impact force of the water pressure column at this distance is likely to cause damage to the cleaning object, and it is prompted to reduce the water pressure. If there is no response, the electric signal is quickly transmitted to the motor battery 11 to cut off the power supply, and the excellent performance of the sensitive response of the three-voice coil linear motor body 2 is used to realize the function of stopping when the power is cut off and emergency braking. Because in direct current, even if the circuit is disconnected, the current will continue to flow along the wire in the circuit until it reaches the other end or load, so the relay 10 is installed. When the power-off signal is received, the metal coil fused in the relay 10 disconnects the current, the magnetic field disappears, and the switch returns to the origin, thereby closing the circuit. Because the three-voice coil linear motor body 2 uses the magnetic field generated by the permanent magnet and the alternating magnetic field generated by the energized coil to generate an interactive driving force, it will stop operating immediately after the power is cut off and will not move due to residual electricity.

[0025] In some embodiments, the surface of the cleaning machine body 1 is provided with anti-slip threads, which can play a good anti-slip role. The surface of the cleaning machine body 1 is respectively installed with a portable handle 13, a long handle 14, and a two-handed handle and a switch button assembly 15, which is convenient for users to hold the device.

[0026] In some embodiments, a charging terminal of the motor battery 11 is equipped with a charging wire head 16 to facilitate charging of the motor battery 11 , and a connecting wire head 17 is installed at the charging terminal of the infrared rangefinder battery 12 to facilitate charging of the infrared rangefinder battery 12 .

[0027] In some embodiments, a cover plate 18 is installed on the surface of the nozzle 4, and a through hole that can be opened and closed freely is provided on the cover plate 18, which solves the problem of needing to replace different nozzles 4 to achieve different cleaning styles and spray water columns of different pressures.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
