Description

Masseur with the motion of knocking

Technical field

[01] the present invention relates to a kind of masseur, this masseur comprises rotation transmission device or can accept the actuating device of this rotational motion, so that subsequently this rotational motion is passed to rotational motion is converted to reciprocating device, make one to be used for moving with the striking mechanism of contact skin.

Background technology

[02] have been found that and a kind ofly kowtowing of skin hit motion help improving blood circulation, and stimulate peripheral nervous system, this can make treated body part produce a kind of sensation of loosening.In addition, be applied to the feeling of fatigue that this motion on the foot can be eliminated foot or lower limb.

[03] known in the prior art multiple by kowtowing the equipment of massaging that hits.For example file FR2472380 has described a kind of such massage machine, and this massage machine comprises a pistol-like shell, and the handle of pistol is used for the assurance of hands, kowtows for one and hits the end that mechanism is installed in shell.Be equipped with one in the shell and drive the electric notor that an axle rotates, this axle makes a crank axle motion, and end of crank is hit device and is connected with kowtowing.The shortcoming of this mechanism be it the volume of heaviness and when operation the noise that produces.This file uses in a modification and severally faces one another and driven one relative to another Magnet that rotates, and one of them Magnet is kowtowed the instrument of hitting and is connected with one.This installation is compacter than the installation of front certainly, but enough big massage moment of torsion can not be provided, and for example massages the moment of torsion that foot needs.

[04] recognizes the massage machine of another kind of same type from file DE813751, but wherein the drive mechanism of instrument uses two cylindrical parts that comprise cam ramp, one of them cylindrical parts can not rotate, but can move freely, another cylindrical parts is connected with a rotating shaft, can rotate, but cannot move.Rotational parts is with an eccentric mode and a rocking lever embedding mutually, and the spherical coupling in mobile part supports this rocking lever, and the end of rocking lever is a massage cushion, and the tip protrusion of massage cushion is outside shell.Therefore massage instrument is driven, so as to carry out one with the bonded reciprocal axial motion of swing that centers on a spherical coupling.This masseur uses a kind of actuating device that comprises several moving parts, structure is increased the weight of, and consume many power.Particularly, this masseur is unsuitable for handling the All Ranges of a people's health, and this instrument in for example can not be with hand held is considered the arciform massage in vola.

[05] recognize that from file US5803916 another kind is used for hand held massage machine, this massage machine comprises a shell, and an electric notor is housed in the shell, and the output shaft of motor drives a massage head and rotates.Massage head comprises a fixed conveyor case that is connected with a base, and base is installed on the output shaft of motor and with motor and rotates.Rotating base comprises several periphery massage parts that are installed on the single spring, and each part has a projection that periodically contacts with a cam ramp that is fixedly mounted in the transmission case.During operation, the massage part rotates, and carries out an axially reciprocating round and round, and their motion separates in time.The device volume that the shortcoming of this massage machine is complex structure on the one hand, gripped by hands in addition big and be unsuitable for handling arch of foot (

), be system's imbalance of the alternate circumferential motion generation of point-like part on the other hand, this uneven meeting produces the running clearance that cause component part to wear and tear too early.

[06] in addition, file DE20110876U has described a kind of massage machine that is used for foot bath, and this massage machine comprises a shell, shell has a tank, tank has the interior space of a sealing, and an electric notor is housed in the interior space, and electric notor drives the device of several processing feet.These masseurs comprise a rotating cylinder, a movable plate or several massage spine that moves both vertically.The massage effect that these adnexaes provide can not the effective stimulus vola.

Summary of the invention

[07] the objective of the invention is to overcome the shortcoming of above-mentioned massage machine, and provide a kind of and can be assigned to the particularly vola part masseur of reliability service again simultaneously of skin area to be processed to effective stimulation to small part.Effectively stimulate and be interpreted as the massage features that is distributed on the processed skin, particularly knock the feature of amplitude, frequency or strength, these features should guarantee the blood circulation of processing region and the effective stimulus of peripheral nervous system, comfortable when guaranteeing to use again simultaneously.

[08] another object of the present invention is dynamic equilibrium and compact masseur, and the size of this masseur is little, structure optimization, simple, and commercial production at low cost.

[09] an additional purpose of the present invention is one and can be installed in a masseur on the massage machine removably, and this masseur can separate with drive system, so that substituted by other masseur or skin-treatment device.

[10] another object of the present invention is one and is installed in a masseur on the massage machine removably, and massage machine can be accepted different massage adnexaes, and these massage adnexaes are removably mounted on again on such masseur.

[11] these purposes can be knocked the masseur that moves by one and reached along the y direction of a shell, one first part is housed in the shell, one of them axial surface of first part comprises at least one projection, at least one axial cam inclined-plane of second a relative part keeps in touch by a return spring and this projection, an electric notor drives second part and rotates around the described longitudinal axis, because first part is fixed on the shell, second part can move freely, second part is coaxial with power transmission shaft, and drives one and knock instrument.

[12] when active second part rotates around its rotating shaft in shell longitudinal axis extension line, this movable members also moves at axial direction, so that coaxial with the longitudinal axis of shell when its cam ramp is promoted by the surperficial to axial projection with first part.This moves axially return spring of opposing, and particularly one is compressed spring, and this spring is compressed when movable members moves, and therefore makes the spring focused energy.This energy is released by cam ramp the time then, or rather, is released at its slope breakaway poing, and this point is called cam and jumps.This energy delivery that discharges is suddenly knocked instrument to the center, so this instrument carries out one in the direction of skin and has the reciprocal axial motion that repeats to kowtow the effect of hitting.

[13] movable second part of the present invention and the coaxial installation of power transmission shaft, second part is accepted the rotation of power transmission shaft, and in masseur of the present invention, power transmission shaft overlaps with the longitudinal axis of shell.Therefore it knocks the direction of motion along power transmission shaft.This installation guarantees the good dynamic equilibrium of system, and retroaction is born by the bearing of power transmission shaft, and the bearing that perhaps for this reason is located in the masseur is born, for example the bearing of the centre part of the connection of an assurance power transmission shaft.This masseur can bear big axial force, therefore is suitable for the processing of the arch of foot.

[14] according to the present invention, second part is driven to be done a rotation and moves bonded motion, and other component part fixed installation of masseur.Therefore masseur of the present invention only need have a single monolithic movable members with the coaxial installation of power transmission shaft of masseur, this part is rotated and mobile, and instrument is knocked at this part drive center.Therefore obtain firm and optimize structure, the parts of this structure and/or a negligible amounts of moving parts.So just reduce the inertia of system, simplified the structure, and reduced the wearing and tearing of component part, therefore guaranteed whole better reliability and longer life-span.

It is found that [15], originally be that second part axial that drives the instrument that knocks is driven rotation when moving.Therefore, if the instrument of knocking is connected with second part, the instrument that then knocks is distributed in pulse on the skin with the coaxial hand of spiral of the longitudinal axis of shell along one.It is arc that this instrument also is used to handle the vola, and generally have the contact area that a size is enough to cover a people's heel area, and for example its diameter can be at 40mm between the 100mm.Therefore, user can be placed on his foot on the handling implement, and handling implement is enough solid, can support the foot of user, and area is enough big, so that surface to be processed is realized stimulating fast and effectively.

[16] contact surface that knocks instrument and skin can cover a kind of soft material of rubber type, so that the processing region of chafe mildly.In addition, the contact surface that knocks instrument and skin is provided with some projections or spine, and all spines knock skin simultaneously.Have been found that when therefore testing, the blood circulation and the peripheral nervous system in the zone that an area of the synergism effective stimulus skin of the screw that all spines knock simultaneously equates with the surface of knocking instrument guarantee the comfortableness of using simultaneously and avoid painful.

[17] in addition, first part comprises the axial cam inclined-plane that at least one contacts with another axial cam inclined-plane of second part at least.

[18] therefore, each in two parts relative to each other has one or several axial slope, and this puts the height on each inclined-plane to compress spring when relative more.The energy that discharges during therefore, by these high points is bigger, therefore stronger to the stimulation of skin.

[19] motion amplitude that knocks instrument preferably is equal to or greater than 2mm, and is preferably between the 3-5mm.

[20] when several zones of skin are tested, have been found that and begin to feel effectively stimulation from the amplitude of 2mm.For the vola that needs stimulate quite deeply, amplitude is preferably 3-5mm.Obtain this amplitude by the size of determining the value that cam jumps, the frequency that the quantity decision of cam ramp stimulates, and the frequency that stimulates is also relevant with the electric notor rotating speed that drives movable members.

[21] in the first embodiment of the present invention, second part comprises some along the downward-sloping axial cam inclined-plane of its rotation transmission direction, and these axial cam inclined-planes abut on the relative inclined-plane of first part that is fixed on the second part bottom.

[22] in this embodiment, the instrument of knocking has the reciprocal axial motion downward trend of following movable members.Return spring keeps in touch retaining element and movable members, upwards applies one and is knocking the opposite thrust of force direction that applies on the instrument with user.Therefore, for example be used to massage under the situation in vola at this instrument, when user leaned against its foot on the instrument of knocking, impulsive force reduced to the limit, and the effect of spring breaks away from retaining element and movable members as a clutch.Under this limiting case, knock motion and no longer pass to skin, keep the rotational motion of movable members at the most, movable members can be connected with the instrument of knocking.

[23] in a second embodiment, second part comprises the acclivitous axial cam of the rotation transmission direction inclined-plane along it, and these inclined-planes abut on the relative inclined-plane of first part that is fixed on the second part top.

[24] in this second embodiment, the reciprocating motion that the instrument of knocking is followed movable members moves up.Return spring applies the thrust of a power equidirectional that applies with user downwards on instrument.This impulsive force that makes instrument is along with user is applied to reclining power and increase on the instrument of knocking.Can obtain a stronger downward massage in this case.

[25] advantageously, masseur of the present invention comprises the device of the power of regulating described return spring.

[26] this adjusting can be undertaken by regulating a simple pressure screw, before making the device operation, compresses spring more or less during the screw action, makes user select massage intensity according to zone to be processed or his sensation.

[27] described second part preferably connects with a centre part that can be connected fast, so that rotate from a motor drive shaft input.

[28] driving parts that connects fast is interpreted as a part that movable members is connected with a drive motor axle, it is centre part, motor one side of centre part and the transmission side of movable members comprise an inner surface that groove or key pin are arranged, perhaps combination of shapes, perhaps other can pass to the rotational motion of motor drive shaft the quick assembled shape of movable members.But people more are ready to have one by a transmission that has rooved face to carry out, because there is rooved face can have one to connect fast, the rotational motion of motor drive shaft are passed to the part that is driven, and give one-movement-freedom-degree of part simultaneously again.This method can be easy to replace this adnexa with a masseur that produces different stimulated from same motor drive shaft masseur of the present invention as an adnexa.

[29] in a modification, second part comprises a running part that connects fast, so that make it very fast from a motor drive shaft input rotation.

[30] this modification is the simplification of a last modification, and in this modification, centre part is cancelled, and movable members itself comprises that forms a part that connects fast, and slotted surface for example is so that directly be connected with motor drive shaft.

[31] advantageously, the installation of knocking instrument can freely be rotated it or is moved relative to described active second part.

Therefore [32] when the instrument that knocks that freely rotates and move abuts on the skin, the reciprocal axial motion of its transduction activity part.The locking of rotating makes this knock instrument is gone back the transduction activity part except the axially-movable of movable members rotation.The advantage of this method is to knock instrument to can be used as an independent part that can break away from movable members, even can be removably mounted on the movable members.

[33] in a modification, the instrument of knocking is fixedly mounted on described active second part.Therefore knock the screw that instrument is verily followed movable members.Many tests of carrying out on the respondent of user show that these are along the deep massage of the pulse assurance skin of spiral part, and skin loosens than simply vertically kowtowing to hit more.

[49] first embodiment of a masseur of the present invention of Fig. 1-5 expression.This masseur comprises that has two the fixedly tubular shells 1 of ear 2, and fixedly ear 2 is used for fixing on the bearing or housing parts of a massage machine not shown in the figures.The top of shell 1 comprises a centre bore 3.The interior antetheca of shell 1 comprises several downward axial cam inclined-planes 5 that are distributed in the periphery of eyelet 3.The preceding inwall of the shell 1 of Gou Chenging forms fixed first part 6 like this.

[50] one second parts 7 are positioned at shell 1, and are coaxial with the longitudinal axis of shell 1.Second part 7 is tubular, and its top comprises a radial flange 8, and several axial cams inclined-plane 9 is arranged above the radial flange 8.Be positioned at flange 8 following cylindrical outer surface and be provided with some water jackets 10.The cylindrical internal surface on second part, 7 tops comprises some inside grooves 11.

The instrument that knocks 4 of [51] mushroom-shapeds comprises a large-area live part 14 (diameter is at least 40mm) that prolongs by a bar 15 downwards.The outer surface of bar 15 fluting, and with inside groove 11 embedding mutually of second part 7.Knock the recline front portion of second part 7 of instrument 4.The instrument that knocks 4 of Xing Chenging is removably installed like this, and can knock instrument with another other of active surface 14 with different geometries and soft degree and replace this and knock instrument 4.

[52] in addition, the active surface 14 that knocks instrument 4 has some to be used to improve the projection 12 of the stimulation of skin, and all projections are knocked motion by spiral and knocked simultaneously.Therefore a bigger zone of skin is upset simultaneously, has so just reduced the time of handling, and has improved efficient.

[53] tubular centre parts 17 drive second parts 7 and rotate, the installation of second part 7 make its relatively centre part 17 move freely.For this reason, centre part 17 comprises a slotted inner surface, this inside groove has some and the water jacket 10 of second part 7 top inside groove 18 and some bottom inside grooves 19 of embedding mutually, the groove embedding mutually of bottom inside groove 19 and rotating drive motor drive shaft not shown in the figures, for example nursing unit of a foot bath equipment.Centre part 17, spring 16, second part 7, knock instrument 4 and shell 1 mutual coaxial installation, and coaxial with the output shaft of CD-ROM drive motor.

[54] this transmission assurance and the 7 input rotations of carrying out from a motor drive shaft by a grooved surface of coaxial mounted second part of power transmission shaft, the while can make it move axially again.Some can be set axially stop, so that limit the stroke of axially-movable of second part 7 and the amplitude of knocking the instrument axially-movable respectively.

[55] centre part 17 comprises a friction flange 21 that forms the roll along trace of ball 22, and friction flange 21 passes through ball 22 rotational support on a friction washer 20.The friction washer 20 that is fixed on shell 1 bottom forms the bearing of rotation centre part 17, and during operation, this bearing can be accepted big axial force.

[56] compression springs 16 are installed between the friction flange 21 of the radial flange 8 of second part 7 and centre part 17.In this was installed, compression spring 16 applied a thrust that makes progress, and the axial cam inclined-plane 5 of first part 6 and the respective shaft of second part 7 are kept in touch to cam ramp.

[57] as shown in Figure 1, the axial cam inclined-plane 9 of second part 7 drives being directed downwards shown in direction that second part 7 rotates and the arrow I along centre part 17.Therefore, second part 7 moves down when rotating, and drives the instrument that knocks 4 motions.Knock motion that instrument 4 passes to processed skin area and be a kind of with rotate combine axially knock motion, the processed in this case skin area person's of being to use foot.The foot of user reduces the impulsive force of instrument 4 at the force compresses spring 16 that reclines that knocks on the instrument 4.If this of user power of reclining is increased to the thrust that overcomes spring, knock 4 feet that successive rotational motion passed to user of instrument.

[58] second embodiment of the present invention is shown in Fig. 6-10, and wherein identical part keeps their reference number.For example the bottom of a tubular shell 1 comprises hard-wired first part 6, and first part 6 is included in the axial cam inclined-plane 5 that makes progress of direction on the axial cam inclined-plane 9 of one second part 7.A compression spring 16 keeps in touch inclined-plane 5 and inclined-plane 9, this spring is installed between the bottom of the top of radial flange 8 of second part 7 and a friction shim 20, friction shim 20 forms the rolling bearing of second part 7, and also can stand axial force during operation.As above-described, 3, one of the eyelets that penetrates upper support shell 1 of second part 7 knock instrument 4 and axially are installed in the rotating shaft of second part 7.

[59] for simplified structure, second part 7 comprises an inner surface that is carved with inside groove 25, and inside groove 25 will directly drive the motor drive shaft engagement of rotating, second part 7 and the coaxial installation of power transmission shaft with one.The same with the embodiment of front, the transmission of rotation is carried out in the direction to arrow I, but in this second embodiment, the cam ramp of second part 7 upwards.Therefore, when driving 7 rotations of second part, knock the trend that instrument 4 has rising.If user abuts on the spring 16 in this case, then more compress this spring, so just increased the impulsive force of the instrument that knocks 4.

[60] frequency of knocking motion depends on the quantity of cam ramp and the speed of motor.For example, to 80 rev/mins motor rotary speeds and three axial cam inclined-planes, obtain the frequency that a per second knocks for 4 times.This frequency is variable, this frequency more preferably greater than or equal per second and knock for 2 times.

[61] same, the amplitude of knocking also is variable, and this amplitude depends on the degree of depth that the cam on the axial cam inclined-plane of first part 6 and second part 7 jumps.

[62] can in the scope that does not exceed claim, consider other modification of the present invention and embodiment.

[63] therefore, the installation of knocking instrument 4 can move freely and rotate it, makes to have only alternating movement upwards to pass to the processed zone of skin.Knock instrument 4 and also can make a single component, perhaps also can be fixed on second part 7, so that follow the motion of second part 7 with second part 7.
