Description
Technical field
The present invention relates to a kind of Hall detection apparatus, detect dress more particularly to a kind of Hall of adjustable distance of reaction
It sets.
Background technique
Hall sensor sensitivity at present is not high, and startup threshold values are generally all in 10GS or more, and producer routinely produces
Kind it is few.Therefore, the distance of reaction for the Hall detection apparatus being made of Hall sensor generally all will not be too long, and
In the fixed-size situation of the magnetic flux of detected object, maximum distance of reaction is fixed and invariable.Certain equipment (such as
Intellectual water meter) on, the magnet steel that detected object cannot use magnetic flux excessive is too big to generate with close equipment metal shell
Interact suction, increases the resistance of water meter movement counter gear transmission, seriously affects the measuring accuracy of equipment.This just gives production
The design of product brings significant limitation.
Summary of the invention
The present invention is intended to provide a kind of Hall detection apparatus of adjustable distance of reaction, to solve the above problems.For this purpose, this
It is as follows to invent the specific technical solution used:
A kind of Hall detection apparatus of adjustable distance of reaction, it may include shell and be mounted in the shell at least
One Hall sensor and at least a magnetic block, the Hall sensor have detection faces and non-detection face, the magnetic block activity
The non-detection face side of the Hall sensor is set, so that the distance between itself and the non-detection face are adjustable.
Further, a mounting groove parallel with the non-detection face, the magnetic block activity peace are equipped in the shell
It can move in the mounting groove and along the mounting groove.
Further, a mounting groove vertical with the non-detection face, the magnetic block activity peace are equipped in the shell
It can move in the mounting groove and along the mounting groove.
Further, the quantity of the Hall sensor is two, and the mounting groove is located at two Hall sensors
On midpoint.
Further, the quantity of the Hall sensor is consistent with the quantity of the mounting groove and corresponds.
Further, the Hall detection apparatus further includes circuit board, and the Hall sensor is welded on the circuit board
Front on, the magnetic block is located at the reverse side of the circuit board.
Further, the magnetic block is magnet steel.
The present invention by adopting the above technical scheme, have the beneficial effect that the present invention by setting and Hall sensor away from
Realize that its distance of reaction is adjustable from adjustable magnetic block, to be conducive to using product design diversification of the invention.

Specific embodiment
Now in conjunction with the drawings and specific embodiments, the present invention is further described.
First embodiment
Fig. 1 shows a kind of Hall detection apparatus of adjustable distance of reaction of first embodiment of the invention.Hall inspection
Surveying device includes shell 1 and the Hall sensor 2 and a magnetic block 3 that are mounted in the shell 1.Hall sensor
2 have detection faces and non-detection face, and magnetic block 3 is movably arranged on the non-detection face side of Hall sensor 2 so that its with it is described
The distance between non-detection face is adjustable.Specifically, a mounting groove 11 parallel with non-detection face is equipped in shell 2, magnetic block 3 is living
It is dynamic to be mounted in mounting groove 11 and be moved along mounting groove 11.Magnetic block 3 is preset in Hall sensor 2 in certain magnetic field,
It is different with the polarity that object to be detected acts on Hall sensor 3, and by adjusting magnetic block 3 at a distance from Hall sensor 2
Make the size change in polarity in magnetic field.Magnetic field is big, and distance of reaction is just remote, and magnetic field is small, and distance of reaction is with regard to closer.
In addition, the Hall detection apparatus may also include circuit board 4.Hall sensor 2 is welded on the front of circuit board 4
In (one side towards detected object), and magnetic block 3 is located at the reverse side of circuit board 4.This configuration simplifies Hall biographies
The installation of sensor 2 simplifies the design of shell 1.
Magnetic block 3 can be permanent magnet or excitation body.Preferably, magnetic block 3 is magnet steel.
The shape of magnetic block 3 can be cylindrical, cube shaped or circular ring shape etc..
Second embodiment
Fig. 2 shows a kind of Hall detection apparatus of adjustable distance of reaction of second embodiment of the invention.The present embodiment
With first embodiment the difference is that: mounting groove 11 is arranged to vertical with the non-detection face of Hall sensor 2.This makes magnetic
Property block 3 and the adjustable extent of the distance between Hall sensor 2 are bigger.
3rd embodiment
Fig. 3 shows a kind of Hall detection apparatus of adjustable distance of reaction of third embodiment of the invention.The present embodiment
With second embodiment the difference is that: the quantity of the Hall sensor 2 of the present embodiment be 2, the quantity of mounting groove 11
It is 2, and is corresponded with Hall sensor 2.This structure adjusts the distance of reaction of Hall sensor 2 individually
It is whole, to be conducive to product design diversification.
It should be understood that the quantity of Hall sensor 2 and mounting groove 11 can be 2 or more, this depends on practical application field
Scape.
