Abstract
The utility model discloses an electric fan is prevented finger hank and is hindered device, including resistance inductor, system control module, outage protective film piece and working battery, the resistance inductor is connected to system control module through digital interface, control signal interface connection to the system control module of outage protective film piece, and the working battery is connected with resistance inductor, system control module and outage protective film piece respectively. Whole utility model protection effect is obvious, can point personnel and close the electric fan operation rapidly when touching the electric fan flabellum, consequently has higher security.
Description
Technical field
The utility model relates to a kind of safety protection device, particularly relates to the anti-finger strand of a kind of electric fan and hinders device.
Background technique
Electric fan in running, because electric fan safety cover space is comparatively large, finger can easily by void contacts to the flabellum run up, larger potential safety hazard can be there is like this for children.The associated safety protective gear arranged for traditional electrical fan does not at present have substantially, and strand wound exists very large randomness and leak, therefore has very large defect in children's safety guarantee to rely on adult to keep an eye on to avoid hair of children green hand to refer to.
Model utility content
The purpose of this utility model: provide a kind of anti-finger strand of electric fan pointed by electric fan blade strand is hindered that can effectively prevent to hinder device.
To achieve these goals, the technical solution of the utility model is:
The anti-finger strand of a kind of electric fan hinders device; comprise resistance inductor, system control module, power failure protection module and working battery; described resistance inductor is connected to system control module by DI Digital Interface; the control signal interface of described power failure protection module is connected to system control module, and described working battery is connected with resistance inductor, system control module and power failure protection module respectively.
The anti-finger strand of above-mentioned electric fan hinders device, and wherein, described resistance inductor have employed pressure sensing chip LPS22HB, and described resistance inductor is by SPI DI Digital Interface delivery pressure induction numerical value.
The anti-finger strand of above-mentioned electric fan hinders device, and wherein, described system control module have employed system control chip ST6220C.
The anti-finger strand of above-mentioned electric fan hinders device, and wherein, described power failure protection module have employed signal relay switch G6EK-134P-US-U.
The anti-finger strand of electric fan hinders device by being arranged between fan turns axle and flabellum by resistance inductor, the barrier force produced because personnel point touching with actual induction, thus cuts off the electricity supply to protect the finger of personnel not by flabellum strand wound.
Accompanying drawing explanation
Fig. 1 is the component connection structure figure that the anti-finger strand of the utility model electric fan hinders device.
Fig. 2 is the fundamental diagram that the anti-finger strand of the utility model electric fan hinders device.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing.
Refer to shown in Fig. 1 and Fig. 2; the anti-finger strand of a kind of electric fan hinders device; comprise resistance inductor 1, system control module 2, power failure protection module 3 and working battery 4; described resistance inductor 1 is connected to system control module 2 by DI Digital Interface; the control signal interface of described power failure protection module 3 is connected to system control module 2, and described working battery 4 is connected with resistance inductor 1, system control module 2 and power failure protection module 3 respectively.
Described resistance inductor 1 is arranged between fan motor rotatingshaft and flabellum, when fan motor rotatingshaft by resistance inductor 1 promote flabellum at the uniform velocity rotate time, the pressure value that resistance inductor 1 is subject to is constant, and described system control module 2 is for gathering this pressure value of monitoring; When there being the finger of personnel to touch flabellum; the pressure value that barrier force due to personnel's finger makes mutually to extrude between fan motor rotatingshaft and flabellum and resistance inductor 1 is responded to increases rapidly; after system control module 2 collects this pressure value increased rapidly by resistance inductor 1; by transmit button amount signal to control the power supply that power failure protection module 3 cuts off fan motor, thus can protect the finger safe of personnel fast.
Two connecting terminals of described power failure protection module 3 are connected respectively to power input and the fan power of fan motor, and the adhesive of two connecting terminals of described power failure protection module 3 and disconnection can control energising and the power-off of fan motor.
Preferably, described resistance inductor 1 have employed pressure sensing chip LPS22HB, and described resistance inductor 1 is by SPI DI Digital Interface delivery pressure induction numerical value.
Preferably, described system control module 2 have employed system control chip ST6220C.
Preferably, described power failure protection module 3 have employed signal relay switch G6EK-134P-US-U.
Whole utility model protection successful, can close rapidly electric fan when personnel's finger touches electric fan blade and run, therefore have higher Security.
