Detailed Description

It should be noted that, in the case of no conflict, the embodiments of the present utility model and the technical features of the embodiments may be combined with each other, and the detailed description in the specific embodiments should be interpreted as an explanation of the gist of the present utility model and should not be construed as unduly limiting the present utility model.

The utility model will be described in further detail with reference to the accompanying drawings and specific examples. In the description of the present utility model, the terms "top," "bottom," and the like are based on the orientation or positional relationship of the cleaning device when in normal use, and it should be understood that these orientation terms are merely for convenience of description and to simplify the description, rather than to indicate or imply that the device or element in question must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the utility model. In the description of the embodiments of the present utility model, the meaning of "plurality" is at least two, that is, includes two and more, for example, two or three, etc., unless specifically defined otherwise.

An embodiment of the present utility model provides a cleaning device 1, please refer to fig. 1 to 4, which includes a mounting base 11, a power device 12, a transmission shaft 13, an execution module 14, a magnet 15 and a sensing element 16.

The power device 12 is connected with the transmission shaft 13 and is used for driving the transmission shaft 13 to rotate relative to the mounting seat 11.

The execution module 14 is arranged at the bottom end of the transmission shaft 13 and is used for installing cleaning elements. That is, the power device 12 drives the transmission shaft 13 to rotate so as to drive the execution module 14 to rotate, thereby realizing the rotation of the cleaning member. Illustratively, the actuator module 14 is removably coupled to the drive shaft 13 for servicing and replacement.

The cleaning member may be a cleaning cloth, a brush, etc., and is installed at the bottom end of the execution module 14 to contact the floor surface to accomplish cleaning.

In an embodiment, the cleaning cloth is detachably mounted on the bottom surface of the execution module 14, for example, the cleaning cloth may be detachably mounted on the bottom surface of the execution module 14 by means of a velcro, so as to be convenient to detach, so as to clean or replace the cleaning cloth.

The magnet 15 is disposed on the execution module 14 and is attached to or near the transmission shaft 13.

The transmission shaft 13 has ferromagnetism, and the transmission shaft 13 can exhibit magnetism by being attached to or arranged close to the magnet 15. That is, closely disposed means that the distance of the drive shaft 13 from the magnet 15 can ensure that the drive shaft 13 exhibits magnetism in the divergent magnetic field of the magnet 15, and that the distance of the drive shaft 13 from the magnet 15 is, for example, not more than 20mm. Illustratively, the drive shaft 13 is a metal shaft.

After the transmission shaft 13 is in contact with the magnet 15, the transmission shaft 13 is magnetic, and when the transmission shaft 13 is separated from the magnet 15, the transmission shaft 13 is demagnetized.

The sensor element 16 is disposed on the mounting seat 11, and includes a sensor 161 and a magnetizer 162, where the sensor 161 is disposed adjacent to the magnetizer 162 and is used for detecting the magnetic field of the transmission shaft 13.

It will be appreciated that if the sensor 161 is able to detect the magnetic signal of the drive shaft 13, it is confirmed that the execution module 14 is located at the bottom end of the drive shaft 13; if the sensor 161 does not detect the magnetic signal of the driving shaft 13, it is confirmed that the execution module 14 is not mounted at the bottom end of the driving shaft 13, that is, the magnetic property of the driving shaft 13 detected by the sensor 161 can detect whether the execution module 14 is mounted in place or whether the execution module 14 is dropped during cleaning.

The proximity guidance magnet 162 is disposed proximate to the sensor 161, and the distance of the guidance magnet 162 from the sensor 161 is typically no more than 20mm. Preferably, the inductive head of sensor 161 and magnetizer 162 are vertically opposite.

In some embodiments, the magnetic conductor 162 is attached to the sensor 161 by means of adhesive or mechanical fastening; in other embodiments, the magnetic conductor 162 is spaced from the sensor 161 by 0 to 10mm, e.g., 0.1mm,0.2mm,0.5mm,1mm,2mm,3mm,5mm,3 to 6mm,10mm, etc.

The specific arrangement form of the adjacent arrangement is not limited.

In one embodiment, sensor 161 is disposed on a side of magnetic conductor 162 that is adjacent to drive shaft 13.

In another embodiment, the magnetic conductor 162 is disposed around the outer periphery of the sensor 161. In this way, the concentration degree of magnetic force lines of the sensor 161 is further improved, the magnetic field focusing effect is stronger, and the detection precision of the sensor 161 is improved.

It will be appreciated that the type of sensing element 16 is not limited and may be a hall sensor, a magnetoresistive sensor, a fluxgate sensor, or the like.

In one embodiment, the sensor 161 is a hall sensor that includes a hall element and a conversion circuit disposed on the hall element, the hall element and the conversion circuit cooperating to convert an induced magnetic field into an electrical signal.

The hall element refers to an element made of a semiconductor material according to hall effect. It is understood that the external magnetic field change can generate an electric signal change through the hall element, and the digital signal or the analog signal is processed and output through the conversion circuit, namely, the function of inducing the external magnetic field and generating the electric signal is realized.

The hall element is illustratively a hall semiconductor chip, and the conversion circuit is integrated on the chip.

The conversion circuit includes an amplifying circuit, a temperature compensation circuit, and a regulated power supply circuit, for example. The amplifying circuit can increase the sensing range of the hall sensor. It can be appreciated that the hall sensor, as a semiconductor device, has a characteristic that its sensitivity drifts with temperature change, which limits its application in high-precision magnetic field measurement, and reduces the influence of high temperature on the measurement result by the temperature compensation circuit. The regulated power supply circuit can improve the accuracy of the measurement result.

It will be appreciated that, due to the limitation of the sensitivity of the sensor 161, the effective detection distance of the sensor 161 is generally 0-20 mm, and in theory, the improvement of the sensitivity of the sensor 161 and the increase of the magnetic field strength of the corresponding magnet 15 can enlarge the detection distance, but in practical application, the structural space is generally limited, the magnet 15 cannot be infinitely increased in size, and once the model selection and the structural design of the sensor 161 are completed, it is difficult to adjust the above two parameters.

The magnetizer 162 can be disposed around the sensor 161 to focus the magnetic field in embodiments of the present utility model.

The material of the magnetizer 162 is not limited, and may be a common metal material with relatively good magnetic permeability. Illustratively, the material of the magnetic conductor 162 may be pure iron, mild steel, ferrosilicon, ferronickel, or the like.

The reason why the magnetizer 162 has high magnetic permeability is that: inside the magnetizer 162, spontaneous magnetization units, called magnetic domains, exist. In general, magnetic domains are arranged in an unordered manner, and thus do not exhibit magnetism to the outside. Under the action of the external magnetic field, the magnetic domains are regularly arranged along the direction of the external magnetic field, so that an additional magnetic field is formed and superposed on the external magnetic field. It will be appreciated that the magnetizer 162 has a gap with the transmission shaft 13 to be measured of the sensor element 16, and that the magnetizer 162 generates a certain magnetization, so that a gap field is formed between the magnetizer 162 and the transmission shaft 13 to be measured. The gap field can concentrate magnetic force lines on one side of the transmission shaft 13 to be measured, which is close to the sensing element 16, so that the attraction force and the magnetic density can be improved, and the magnetic field is increased. That is, the magnetic conductor 162 may change the magnetic field lines of the gap field, thereby changing the magnetic flux and thus the magnetic field strength.

In the cleaning device 1 provided by the embodiment of the utility model, the execution module 14 can be detected through the sensing element 16 and the magnet 15, namely, the magnetic property of the transmission shaft 13 is sensed by the sensing element 16 to perform the in-situ detection of the execution module 14, so that the detection precision is high; meanwhile, on the basis of adopting the finished sensor 161, the detection performance of the sensor 161 can be improved by adding the magnetizer 162 during installation, the cost is low, and the expansion and the use of the sensor 161 are facilitated.

In one embodiment, the magnetizer 162, the sensor 161 and the portion to be detected of the transmission shaft 13 are at the same height, and the magnetizer 162, the sensor 161 and the portion to be detected of the transmission shaft 13 are disposed close to each other.

It can be understood that the portion to be detected of the transmission shaft 13 is exposed, the magnetic field signal is strong, and the distance between the sensor 161 and the portion to be detected of the transmission shaft 13 is reduced by arranging the magnetizer 162, the sensor 161 and the portion to be detected of the transmission shaft 13 at the same height, so that the detection precision is improved.

By closely positioned is meant the maximum distance that the sensor 161 can detect the magnetic field signal of the portion of the drive shaft 13 to be detected. Illustratively, the distance between any two of the magnetizer 162, the sensor 161, and the portion to be detected of the transmission shaft 13 is no more than 20mm.

It will be appreciated that the shape of the magnetic conductor 162 is not limited, and in one embodiment, the magnetic conductor 162 may be a sheet, a block, a cylinder, a sphere, an ellipsoid, or any other shape that is convenient for installation or shaping, and the size of the magnetic conductor 162 in the direction of the arrangement of the sensor 161 and the magnetic conductor 162 is determined according to the shape of the magnetic conductor 162.

In some embodiments, the magnetic conductor 162 is sheet-shaped, the sensor 161 is disposed on one side of the magnetic conductor 162 in the thickness direction, and the size of the magnetic conductor 162 in the arrangement direction of the sensor 161 and the magnetic conductor 162 is 0mm to 8mm, for example, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, or the like. It is understood that when the magnetizer 162 is in a sheet shape, the size of the magnetizer 162 in the arrangement direction of the sensor 161 and the magnetizer 162 is 0.1mm to 4mm, and when the magnetizer is in a thick sheet shape, the size of the magnetizer 162 in the arrangement direction of the sensor 161 and the magnetizer 162 is 4mm to 8mm. Illustratively, the cross-sectional shape of the magnetic conductor 162 is rectangular with sides of 5mm to 15mm, e.g., 5mm, 7.5mm, 10mm, 12.5mm, 15mm.

In still other embodiments, the magnetic conductor 162 is block-shaped, and the magnetic conductor 162 has a dimension in the direction of arrangement of the sensor 161 and the magnetic conductor 162 of 10mm to 20mm, for example, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, or the like. Illustratively, the cross-sectional shape of the magnetic conductor 162 is rectangular with sides of 4mm to 8mm, e.g., 4mm, 5mm, 6mm, 7mm, 8mm.

In still other embodiments, the magnetic conductors are columnar, and the size of the magnetic conductors 162 in the direction of arrangement of the sensor 161 and the magnetic conductors 162 is 10mm to 20mm, for example, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, or the like.

For example, referring to fig. 2 to 3, the cross-sectional shape of the magnetizer 162 is circular, and the diameter is 4mm to 8mm, for example, 4mm, 5mm, 6mm, 7mm, 8mm, and the sensor 161 is disposed at one axial side of the magnetizer 162. In this way, the dimension of the magnetizer 162 in the top-bottom direction of the cleaning device 1 is increased, and the magnetism collecting effect of the magnetizer 162 is improved. It is to be understood that the magnetizer 162 has a circular axis, and the dimension in the direction of arrangement of the sensor 161 and the magnetizer 162, that is, the length of the axis, may be appropriately increased to a dimension of 10mm to 20mm, for example, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, or the like. It is understood that, when the dimension of the magnetizer 162 in the arrangement direction of the sensor 161 and the magnetizer 162 is smaller than 10mm, the magnetic field generated by the magnetization of the magnetizer 162 is insufficient to influence the magnetic field variation of the transmission shaft 13, and the magnetic focusing effect is poor; when the dimension of the magnetizer 162 in the arrangement direction of the sensor 161 and the magnetizer 162 is larger than 20mm, the magnetism collecting effect is not significantly improved compared with 20mm, and the material is wasted. In this way, the magnetic field generated by the magnetization of the magnetizer 162 increases the magnetic field strength near the sensor 161, and at the same time, saves materials and reduces manufacturing cost.

In still other embodiments, the magnetic conductor 162 is an ellipsoid, the sensor 161 is disposed on one side of the magnetic conductor 162 in the long axis direction, and the magnetic conductor 162 has a dimension in the direction of arrangement of the sensor 161 and the magnetic conductor 162 of 10 to 30mm, for example, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 25mm, 30mm, or the like.

In an embodiment, referring to fig. 2 to 3, the magnetizer 162 is in a column shape, the sensor 161 is disposed at one side of the magnetizer 162 along the length direction, and the length direction of the magnetizer 162 is perpendicular to the transmission shaft 13. Thus, the magnetism collecting effect of the magnetizer 162 is increased.

In one embodiment, referring to fig. 2 to 3, the mounting base 11 is formed with a guiding channel 11a extending along the top-bottom direction of the cleaning device 1, and the top end of the transmission shaft 13 is disposed in the guiding channel 11a. The sensor 161 is provided on the outer surface of the side wall of the guide passage 11a. That is, the sensor 161 is disposed opposite to the transmission shaft 13 at both sides of the side wall of the guide passage 11a. Thus, the distance between the sensor 161 and the transmission shaft 13 is reduced, the magnetic field intensity at the sensor 161 is increased, and the sensor 161 and the transmission shaft 13 are arranged at opposite intervals so as to enhance the magnetic field intensity, so that the detection reliability is further improved.

In one embodiment, referring to fig. 2 to 3, the mounting base 11 includes a housing 111 and a barrel 112 protruding upward from a top wall of the housing 111.

Illustratively, the housing 111 and the barrel 112 are of unitary construction, such as a unitary sheet metal part. That is, the mounting seat 11 is an integral sheet metal part, and is formed by molding the same metal plate through a cold working process. For example, the structure is finally obtained after blanking, stamping, bending and other processes. In this way, the structural strength and rigidity of the mount 11 can be improved.

In some embodiments, the same metal plate is cut into a required shape by a blanking process; the cut sheet is punched, and the cylindrical portion 112 is punched, wherein a portion of the sheet that is not punched and bent is a non-protruding region, that is, the non-protruding region corresponds to a reference standard of a process of punching, bending, and the like of the sheet.

The power transmission form of the power unit 12 is not limited, and the power unit 12 may be connected to the transmission shaft 13 by gears, pulleys, toothed chains, or the like, for example, so that the power unit 12 may rotate the transmission shaft 13.

In an embodiment, referring to fig. 2, the power device 12 includes a gear 121, and the gear 121 is disposed in the cavity 111a and sleeved on the transmission shaft 13 to drive the transmission shaft 13 to rotate. It will be appreciated that the power module 122 of the power plant 12 includes a motor and a reduction gear set, the output shaft of the motor being meshed with the reduction gear set, the reduction gear set being meshed with the gear 121 to drive the drive shaft 13 to rotate.

The gear 121 is keyed to the transmission shaft 13. The key connection may be a spline connection, a flat key connection, or the like. The key connection of the transmission shaft 13 and the gear 121 means that one of the outer circumferential surface of the transmission shaft 13 and the inner circumferential surface of the gear 121 is provided with a key, and the other of the outer circumferential surface of the transmission shaft 13 and the inner circumferential surface of the gear 121 is provided with a key groove, the key being engaged with the key groove.

The key and keyway engagement keeps the gear 121 and drive shaft 13 rotating in unison.

The top end of the drive shaft 13 is at least partially structured above the top wall of the housing 111.

In one embodiment, referring to fig. 2 and 3, a mounting groove 111b is formed on the top surface of the housing 111, and the sensor element 16 is disposed in the mounting groove 111b. In this way, at least part of the structure of the transmission shaft 13 and the sensing element 16 are located on the same plane, so that the measurement distance between the transmission shaft 13 and the sensing element 16 is reduced, and the detection precision is improved.

In one embodiment, referring to fig. 1 and 2, the cleaning device 1 includes an end cap 17, and the end cap 17 covers the mounting groove 111b and the top side of the barrel 112.

The magnet 15 and the transmission shaft 13 are arranged in the limit groove 14a, so that the structure is compact, and the dimension of the execution module 14 in the height direction is saved.

In one embodiment, referring to fig. 2, the cleaning device 1 includes a bottom cover 18, and the bottom cover 18 covers the bottom side of the limiting groove 14 a. In this way, the problem that the magnet 15 is exposed on the bottom surface of the execution module 14, so that the magnet 15 is corroded, faults are caused or the emission intensity of magnetic signals is disturbed due to the fact that the magnet 15 is soaked by liquid on the ground to be cleaned or foreign matters influence the magnet 15 can be avoided, and further the service life of the magnet 15 and the stability and reliability of magnetic signals are improved.
