Abstract
The utility model discloses an electromagnetic shell knocker which comprises a magnetic circuit subassembly and a knocker head subassembly. The magnetic circuit subassembly comprises an electromagnetic coil, a magnetic conducting plate and a straight-through damping sleeve. The knocker head subassembly comprises a knocker head main body and an armature iron. The electromagnetic shell knocker is characterized in that the armature iron and the damping sleeve are both straight-through structures; the knocker head subassembly, consisting of the straight-through armature iron and the knocker head made of non-magnetic conducting material which are coaxially fixed, is installed at the center of the straight-through damping sleeve of the magnetic circuit subassembly and can move along the axis; a closed magnetic circuit formed by the armature iron and the magnetic circuit subassembly can form a magnetic circuit air gap during the relative motion; and the knocker head is driven by electromagnetic force to perform knocking actions.
Description
Technical field
This utility model relates to a kind of electromagnetic type knocking device, particularly relates to a kind of electromagnetic type knocker that is applicable to massage apparatus.
Background technology
The electromagnetic type knocker that uses in the at present common massage apparatus, usually all have parts such as guiding mechanism, back-moving spring and location cushion, except its structure relative complex, major defect is also must exert pressure to striking head when in use, allow armature leave initial position, make that thereby occurring air-gap in the knocker magnetic circuit produces percussion power by magnetic field, if do not exert pressure then knocker can't be worked.
The utility model content
The purpose of this utility model is to overcome the prior art defective, provide a kind of simple in structure, cost is low, need not electromagnetic type knocker that striking head is exerted pressure and just can be made the masseur operate as normal.
In order to realize above purpose, this utility model is by the following technical solutions: a kind of electromagnetic type knocker, comprise magnetic circuit assembly and striking head assembly, described magnetic circuit assembly includes solenoid, magnetic conductive board and through type shock-absorbing sleeve, the striking head assembly includes striking head body and armature, it is characterized in that: armature and shock-absorbing sleeve are straight-through structure, coaxial fixing and striking head assembly that form is installed on the through type shock-absorbing sleeve central authorities of magnetic circuit assembly by through type armature and non-magnet material striking head, and can move along the shock-absorbing sleeve central axial line, the closed magnetic circuit that armature and magnetic circuit assembly are formed can form the magnetic circuit air-gap when relative motion, described striking head body forms hammer action by the electromagnetic force drive.
The beneficial effects of the utility model are: this utility model has utilized the effect of gravity, and electric magnet produces air-gap automatically and works, and this utility model has only kept the most basic structure of electric magnet, can significantly reduce manufacturing cost.
Below in conjunction with accompanying drawing this utility model is described in further detail
Description of drawings
Fig. 1 is this utility model specific embodiment schematic appearance;
Fig. 2 is this utility model specific embodiment structural representation;
The specific embodiment
As Fig. 1, shown in Figure 2, a kind of electromagnetic type knocker, comprise magnetic circuit assembly and striking head assembly, described magnetic circuit assembly includes solenoid 4, magnetic conductive board 5,6 and the through type shock-absorbing sleeve, the striking head assembly includes striking head body 1 and armature 2, it is characterized in that: armature 2 and shock-absorbing sleeve are straight-through structure, coaxial fixing and striking head assembly that form is installed on the through type shock-absorbing sleeve central authorities of magnetic circuit assembly by through type armature 2 and non-magnet material striking head, and can move along the shock-absorbing sleeve central axial line, armature 2 can form the magnetic circuit air-gap with the closed magnetic circuit that the magnetic circuit assembly is formed when relative motion, described striking head body forms hammer action by the electromagnetic force drive.Described magnetic conductive board 5,6 is connected and fixed by two magnetic sheets up and down and forms.
Operation principle of the present utility model is as follows: the appropriate location that is mounted to massage apparatus when the electromagnetic type knocker, and when striking head contacts with the user body surface, the magnetic circuit assembly can move down in the effect of gravity, forces armature 2 to be pushed to move away the closed magnetic circuit position and forms air-gap.If connect the control power supply at this moment for solenoid 4, promptly can produce magnetic field in the coil armature 2 is attracted to the magnetic circuit closure, thereby produce percussion power.If with the installation that turns over of electromagnetic type knocker, then armature 2 assemblies also can be because of the effect slippage of the gravity position beyond the closed magnetic circuit, thereby produces the effect identical with preceding surface state.
Certainly, protection domain of the present utility model is not limited only to above-mentioned embodiment, and any improvement to this utility model unsubstantiality all should be within this utility model protection domain.
Claims (2)
1, a kind of electromagnetic type knocker, comprise magnetic circuit assembly and striking head assembly, described magnetic circuit assembly includes solenoid, magnetic conductive board and through type shock-absorbing sleeve, the striking head assembly includes striking head body and armature, it is characterized in that: armature and shock-absorbing sleeve are straight-through structure, coaxial fixing and striking head assembly that form is installed on the through type shock-absorbing sleeve central authorities of magnetic circuit assembly by through type armature and non-magnet material striking head, and can move along the shock-absorbing sleeve central axial line, the closed magnetic circuit that armature and magnetic circuit assembly are formed can form the magnetic circuit air-gap when relative motion, described striking head body forms hammer action by the electromagnetic force drive.
