Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
embodiment 1:goal of the invention of the present utility model is to overcome and adopts tongue tube to carry out character wheel count the too much manual intervention of the installation process need that cause, and easily occur that micro-leakage causes measuring inaccurate problem, a kind of magnetic induction chip that adopts is provided to count, thus avoid described character wheel counting device production run to need too much manual intervention and there will not be the micro-leakage of tongue tube to cause measuring inaccurate magnetic induction character wheel counter: to achieve these goals, the technical solution adopted in the utility model is:
A kind of magnetic induction character wheel counter, as shown in Figure 1, comprises,
Character wheel group 1, described character wheel group comprises eight character wheels coaxially arranged, and the circumferential edges of a side of described character wheel is evenly equipped with a circle stepping and dashes forward tooth, and opposite side circumferential edges is provided with carry and dashes forward tooth; Connected by carry gear 11 between adjacent character wheel; The character wheel 12 that one is provided with ferromagnetic material 121 is included in described character wheel group 1; Ferromagnetic material 121 described in the present embodiment is iron block, the position (as the position of numeral 0 or the position of numeral 9) at described iron block any digital place on described character wheel 12.
Magnetic induction unit, with described corresponding being arranged on circuit board 3 in character wheel 12 position being provided with iron block, comprising in magnetic induction chip 22(the present embodiment that a U-shaped magnetic patch 21 and is arranged in described magnetic patch 21U type recess and adopts chip MMG845DG);
The described iron block 121 rotated with character wheel 12 causes described magnetic patch 21 changes of magnetic field when magnetic patch 21 corresponding to it, and described magnetic induction chip 22 is for responding to described changes of magnetic field and exporting count pulse to described circuit board 3.
In the present embodiment, described in be provided with iron block 121 character wheel 12 often turn around (namely described iron block 121 near described magnetic patch 21 once) once count.Simultaneously its also by shown carry gear 11 by rotation situation transmission carry to adjacent gear, in like manner all carry out carry transmission by shown peri position gear 11 between each gear, adopt naked eyes mode directly to carry out reading to character wheel to facilitate user.
It should be noted, the data processing module (accessible site is on a circuit board) receiving count pulse processes count pulse and is delivered to display unit to carry out display be general knowledge known in this field, those skilled in the art are under the prerequisite that can receive count pulse, have multiple usual way to realize above-mentioned functions, the utility model does not specifically disclose the concrete structure of data processing module and should not be considered to insufficient disclosure to the disposal route of described count pulse.
In addition, described character wheel 12 is arranged ferromagnetic material (be iron block in the present embodiment, but all can cause the ferromagnetic material of magnetic patch changes of magnetic field all can realize being similar to the effect of iron block, as iron film, cobalt block, cobalt film, nickel block, nickel film or magnet steel etc.); Once count because character wheel in the present embodiment 4 often turns around, therefore described iron block 41 allows to be arranged on Any Digit position, and it can not affect actual measurement simultaneously.In fact the numeral on described character wheel is only for convenience of eye-observation, and whether it marks the tally function not affecting described magnetic induction character wheel counter.Therefore when only on character wheel 4 optional position, the annular face of cylinder be provided with a ferromagnetic material, and do not arrange any display numeral, should think and belong to the utility model protection domain.
embodiment 2:as different from Example 1, as shown in Figure 2, in the present embodiment, on the character wheel 12 being provided with ferromagnetic material, the position of each numeral is provided with iron block 121.
During use, along with the described rotation being provided with the character wheel 12 of iron block 121, whenever having an iron block 121 near magnetic patch 21 (when a numeral forwards to below described magnetic patch 21), the magnetic field of described magnetic patch 21 changes, and exports count pulse after described magnetic induction chip 22 senses this changes of magnetic field.
It should be noted, the shape of described iron block 121 is not defined as the circle in Fig. 1 or Fig. 2, and can be any shape, bar shaped as shown in Figure 3.In addition, described iron block for being embedded in the surface of described character wheel 12, or can protrude from the surface of described character wheel 12.
embodiment 3:as different from Example 1, in described character wheel group 1, all character wheels are the character wheel 12 being provided with iron block 121 to the present embodiment, and are eachly provided with all corresponding magnetic induction unit of iron block 121 character wheel 12.In the present embodiment, magnetic barrier sheet is provided with to prevent from, between character wheel and character wheel, magnetic interference occurs between each character wheel 12 being provided with iron block 121.
It should be noted, be coaxial connection between each character wheel in the group of character wheel described in the utility model 1, namely each character wheel is for rotate around same axle, as long as therefore this axle is fixed to after in a support or framework, the circuit board being provided with magnetic induction unit is placed on relevant position can realize, those skilled in the art are after seeing the content and accompanying drawing that the utility model provides, can be beyond all doubt realize the technical program, should because not mentioning framework or support in patent and thinking this patent insufficient disclosure.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
