In some examples of the utility model, as shown in Figure 12, Figure 13, Figure 14, without extraneous pressing force, hair Electric installation 100 is in limes superiors state, at this point, movable device 20 is maintained at limes superiors under the elastic force effect of reset spring 401 The upper surface of position, the first pole core 202 and permanent magnet 201 is in close contact, the second pole core 203 and permanent magnet 201 Lower surface is in close contact, and the second adjutage 1021 contacts with the second pole core 203, the first pole core 202 be equipped with the One joining piece 2021 is contacted with the first adjutage 1023.

In some examples of the utility model, as shown in Figure 15, Figure 16, Figure 17, movable device 20 is as shown in figure 15 In the case that arrow direction position is by downward extraneous pressing force, movable device 20 is in limit inferior state, at this point, moving machine Structure 20 overcomes the elastic force effect of reset spring 401 to swing to lower limit position, and the first pole core 202 is upper with permanent magnet 201 The lower surface of intimate surface contact, the second pole core 203 and permanent magnet 201 is in close contact, the second adjutage 1021 and first Pole core 202 contacts, and the second joining piece 2031 is contacted with third adjutage 1022, it is assumed that and permanent magnet 201 is above the pole N, under Face is the pole S, at this time in magnetic circuit the magnetic line of force direction are as follows: the pole N of permanent magnet 201 → 202 → the second adjutage of the first pole core 1021 → E, 102 → third of shaped iron core adjutage, 1022 → the second joining piece, 2031 → the second 203 → permanent magnet of pole core 201 The pole S, so, the magnetic line of force at the second adjutage 1021 that E shaped iron core 102 is equipped at this time arrow side shown in Figure 16 To.After extraneous pressing force removes, power generator 100 is restored under the elastic force effect of reset spring 401 from limit inferior state Limes superiors state.

In some examples of the utility model, in the case where movable device 20 is depressed downwardly power, power generation dress 100 are set during from limes superiors state change to limit inferior state, at the beginning, due to the work of the adsorption magnetic force of E shaped iron core 102 With the second adjutage 1021 is kept in contact with the second pole core 203, and the first joining piece 2021 and the first adjutage 1023 are kept Contact, at this point, the first elastic slice 1031 and the second elastic slice 1032 become downwards as the opposite shell 30 of E shaped iron core 102 moves downward Shape produces E shaped iron core 102 at this point, elastic slice deforms downwards when E shaped iron core 102 is moved downwardly to certain distance with respect to shell 30 Raw upward elastic force, greater than the adsorption capacity of the second adjutage 1021 and the second pole core 203, E shaped iron core 102 will be lost It balances, the elastic potential energy stored in elastic slice deformation process can be broken out, so that the second adjutage that E shaped iron core 102 is equipped with 1021 generate biggish upward acceleration, so that the second adjutage 1021 is leaned on the shorter time to the first pole core 202 It closely and contacts, so that passing through second by the magnetic line of force direction in the second adjutage 1021 with shorter time-commutate mode The magnetic line of force unit time of adjutage 1021 changes faster, according to Faraday's electromagnetic induction law, so that being wound on second Coil 101 on adjutage 1021 generates higher electromotive force, generates bigger energy, therefore the first elastic slice 1031 and the second elastic slice 1032 design plays the effect for improving 100 generating efficiency of power generator.

According to the wireless switching of the utility model embodiment, the power generator 100 including above-described embodiment, the power generator 100 settings are mounted on wireless switching, can convert mechanical energy into electric energy, can satisfy wireless switching and Internet of things node hair Energy requirement needed for penetrating signal, it is inconvenient brought by wireless switching replacement battery and maintenance so as to solve the problems, such as, also, The power generator 100 has the characteristics that structure is simple, compact-sized, generating efficiency is high, long service life.
