Description

Technical Field

[0001] This utility model relates to the field of sensor cleaning technology, specifically to an automatic compensation self-cleaning device. Background Technology

[0002] In power plants, environmental testing, aquaculture, and water / wastewater treatment, sensors are commonly used to monitor water quality. For example, sensors are frequently used to detect chlorine concentration, oxygen concentration, conductivity, pH / ORP, and temperature in water. Simply placing the sensor probe in the water is sufficient for measurement. However, because the sensor probe is immersed in water for extended periods, scale, deposits, or organic matter can easily form on its surface, affecting the accuracy of the measurement results. In such cases, it is necessary to clean the surface of the sensor probe to ensure accurate and stable measurement results.

[0003] Existing sensor cleaning devices, when cleaning sensor probes, are prone to damaging the sensors during use because the bristles are rigidly connected. Furthermore, the bristles are not easy to replace, making them inconvenient for users. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic compensation and self-cleaning device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An automatic compensation self-cleaning device includes a housing. A control circuit board and a battery are fixedly installed inside the housing. An electromagnetic coil is fixedly installed on the inner wall of one end of the housing. Inner and outer isolation members are provided inside the electromagnetic coil. A magnetic rotor is rotatably installed inside the inner and outer isolation members. A compensation gap is left between one end of the magnetic rotor and the side wall of the inner and outer isolation members. A connecting shaft is fixedly installed at the middle position of one end of the magnetic rotor. A brush holder is installed at one end of the connecting shaft. Brush bristles are fixedly installed at one end of the brush holder.

[0006] In a preferred embodiment, the ends of the inner and outer isolation components are fixedly mounted on the housing, and a multi-pole permanent magnet is provided inside the magnetic rotor. The magnetic rotor contains a multi-pole permanent magnet, which interacts with the electromagnetic coil to form an electromagnetic drive rotation device. The inner and outer isolation components seal and separate the electromagnetic coil and the magnetic rotor to the inner and outer sides.

[0007] In a preferred embodiment, a charging interface is provided at the outer end of the housing. The battery is electrically connected to the charging interface and the electromagnetic coil. The charging interface facilitates charging of the battery, while the battery can supply power to the electromagnetic coil. The control circuit board controls the electromagnetic coil to generate an alternating magnetic field.

[0008] In a preferred embodiment, the brush holder has a mounting hole at the end away from the bristles, a mounting groove is formed on the inner side wall of the mounting hole, a positioning rod is slidably disposed inside the mounting groove, and a positioning groove matching the positioning rod is formed on the outer side wall of the connecting shaft. The brush holder and the connecting shaft can be fixed by inserting the positioning rod into the positioning groove.

[0009] In a preferred embodiment, a limiting groove is provided on the inner sidewall of the mounting hole, and a limiting protrusion is provided on the outer side of the connecting shaft. The limiting groove and the limiting protrusion enable the positioning of the connecting shaft and the brush holder, and ensure the docking of the positioning rod and the positioning groove.

[0010] In a preferred embodiment, a spring is provided inside the mounting groove at the upper end of the positioning rod, and a handle is fixedly provided at the upper end of the positioning rod. The upper end of the handle is located at a groove opened on the surface of the brush seat, and a cover plate is slidably provided at the groove. The spring allows the positioning rod to be tightly pressed against the positioning groove, while the handle facilitates the pulling of the positioning rod out of the positioning groove, and the cover plate can limit the movement of the handle.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses an electromagnetic coil and a magnetic rotor to realize the rotation of the cleaning device, and leaves a certain compensation gap between the magnetic rotor and the inner and outer isolation parts. When in use, the sensor presses the magnetic rotor to the position of contact with the inner and outer isolation parts through the brush bristles and brush seat, so that the magnetic field generated by the multi-pole permanent magnet and the electromagnetic coil cannot be aligned. At this time, the magnetic force of the magnetic field will have a magnetic spring effect that pulls the magnet back to the balance point. When the brush bristles wear, the magnetic force of the magnetic field drives the magnetic rotor to automatically compensate to the balance point until the compensation margin is used up. Then the magnet in the magnetic rotor is aligned with the magnetic field of the electromagnetic coil and returns to the balance point. This can effectively realize the automatic compensation of the cleaning device and prevent the brush bristles from damaging the sensor. 2. This utility model has a structure including mounting holes, positioning rods, positioning grooves, limiting protrusions, limiting slides, springs, handles, and cover plates. The positioning rods are inserted into the positioning grooves to install and fix the brush holders. The structure is simple, easy to operate, and facilitates the replacement of brush bristles. Moreover, the cover plate prevents the positioning rods from sliding out of the positioning grooves, making the connection of the brush holders more stable. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-4 This utility model provides an automatic compensation and self-cleaning device, the technical solution of which is as follows: An automatic compensation self-cleaning device includes a housing 1. A control circuit board 2 and a battery 3 are fixedly installed inside the housing 1. An electromagnetic coil 4 is fixedly installed on the inner side wall of one end of the housing 1. An inner and outer isolation member 5 is provided inside the electromagnetic coil 4. A magnetic rotor 6 is rotatably installed inside the inner and outer isolation member 5. A compensation gap 7 is left between one end of the magnetic rotor 6 and the side wall of the inner and outer isolation member 5. A connecting shaft 8 is fixedly installed at the middle position of one end of the magnetic rotor 6. A brush holder 9 is installed at one end of the connecting shaft 8. Brush bristles 10 are fixedly installed at one end of the brush holder 9.

[0016] In a preferred embodiment, the ends of the inner and outer isolation members 5 are fixedly mounted on the housing 1. A multi-pole permanent magnet is provided inside the magnetic rotor 6. After the electromagnetic coil 4 is energized by the control circuit board 2, it generates an alternating magnetic field. The multi-pole permanent magnet inside the magnetic rotor 6 will be magnetically pulled toward the electromagnetic coil 4 until its polarity is aligned with the magnetic field of the electromagnetic coil 4 and stabilizes at the equilibrium point. At this time, if an external force is used to push the magnetic rotor 6 back and forth along the rotor axis, the magnetic rotor 6 will automatically return to the equilibrium point under the action of the magnetic force. The full force of the magnetic field in the axial direction constitutes an equivalent "magnetic spring". Even without physical constraints, the magnetic rotor can be stabilized in a specific position.

[0017] In a preferred embodiment, the outer end of the housing 1 is provided with a charging interface 11, the battery 3 is electrically connected to the charging interface 11 and the electromagnetic coil 4, the battery 3 can supply power to the device, and the control circuit board 2 can control the alternating magnetic field of the electromagnetic coil 4.

[0018] In a preferred embodiment, the brush holder 9 has a mounting hole 12 at the end away from the bristles 10. A mounting groove 13 is formed on the inner wall of the mounting hole 12. A positioning rod 14 is slidably disposed inside the mounting groove 13. A positioning groove 15 matching the positioning rod 14 is formed on the outer wall of the connecting shaft 8. A limiting groove 16 is formed on the inner wall of the mounting hole 12. A limiting protrusion 17 is provided on the outer side of the connecting shaft 8. A spring 18 is disposed inside the mounting groove 13 at the upper end of the positioning rod 14. The upper end of the positioning rod 14 is fixedly mounted... A handle 19 is provided, the upper end of which is located in a groove 20 on the surface of the brush holder 9. A cover plate 21 is slidably disposed in the groove 20. In actual use, the limiting protrusion 17 on the connecting shaft 8 is slid into the limiting groove 16 on the inner side wall of the mounting hole 12. When it is slid into the extreme, the positioning rod 14 is engaged with the positioning groove 15. Under the action of the spring 18, the positioning rod 14 extends into the positioning groove 15, closing the cover plate 21 and preventing the handle 19 from moving under the action of external force. Damping rubber is provided on the side walls at both ends of the cover plate 21, and a certain force needs to be applied to move it.

[0019] The working principle of this utility model is as follows: When in use, hold the housing 1 and place the brush bristles 10 against the sensor to be processed. The control circuit board 2 controls the electromagnetic coil 4 to generate an alternating magnetic field. The magnetic rotor 6 contains a multi-pole permanent magnet, which interacts with the electromagnetic coil 4 to form an electromagnetic drive rotation device. This causes the magnetic rotor 6 to drive the connecting shaft 8, brush holder 9, and brush bristles 10 to rotate. The brush bristles 10 clean the sensor. During the cleaning process, when the sensor presses the magnetic rotor 6 into contact with the inner and outer isolation parts 8 through the brush bristles 10 and brush holder 9, the magnetic field generated by the multi-pole permanent magnet and the electromagnetic coil 4 cannot be aligned. At this time, the magnetic force will have a magnetic spring effect that pulls the magnet back to the balance point. When the brush bristles 10 wear down, the magnetic force drives the magnetic rotor 6 to automatically compensate to the balance point until the compensation margin is used up. Then, the magnet in the magnetic rotor 6 aligns with the magnetic field of the electromagnetic coil 4 and returns to the balance point. This can effectively realize the automatic compensation of the cleaning device and prevent the brush bristles from damaging the sensor. When the bristles 10 need to be replaced, slide the cover plate 21 and lift the handle 19 upwards, so that the handle 19 pulls the positioning rod 14 to move. The positioning rod 14 slides out of the positioning groove 15, and then the connecting shaft 8 can be pulled out from the mounting hole 12. When installing the bristles 10, insert the limiting protrusion 17 on the outside of the connecting shaft 8 into the mounting hole 12 along the limiting groove 16. When the connecting shaft 8 can no longer go deeper, the positioning rod 14 corresponds to the positioning groove 15. Release the handle 19, and the positioning rod 14 is inserted into the positioning groove 15 under the action of the spring 18. Then close the cover plate 21 to realize the connection and fixation of the connecting shaft 8 and the brush holder 9.

[0020] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
