Abstract
Description
Technical Field
[0001] This utility model relates to the field of scraping massage devices, and in particular to a scraping massage component. Background Technology
[0002] Massagers are ubiquitous in daily life. They are mainly used to relax muscles and stimulate body parts, relieving muscle fatigue and providing a pleasant feeling. They are widely loved health care products.
[0003] Currently, massagers offer a variety of massage methods, categorized by their working principles and uses into vibration massagers, oscillating massagers, and scraping massagers, among others. Scraping massagers are often used for gentle skin pulling and auxiliary scraping massage techniques. These massagers primarily consist of a handheld unit and a massage head mounted on it. Their working principle involves a motor module within the handheld unit driving the massage head to rotate, pressing the rotating head against the skin to create a scraping effect. However, commercially available scraping massagers often use ordinary unidirectional motors, limiting the massage head's rotation to one direction. While the massage head is often made of soft materials like silicone or plastic to enhance comfort, this also makes it prone to generating static electricity when scraping against the skin. The combined effect of static electricity and the unidirectional rotation of the massage head causes hair to easily become entangled on the head, resulting in hair tearing, damaging the skin and hair follicles, and potentially burning out the motor due to increased load. Utility Model Content
[0004] The purpose of this invention is to provide a scraping massage component that avoids the scraping massager from getting tangled in the hair, prevents the hair from being torn, so as to avoid damaging the skin and hair follicles, and at the same time avoids increasing the load on the motor to extend the service life of the motor.
[0005] The technical solution provided by this utility model is as follows: a scraping massage component, including a housing and a massage head disposed on one side of the housing, a motor module disposed inside the housing, and a rotating shaft disposed on the massage head, the rotating shaft passing through the side of the housing and extending into the interior of the housing; the rotating shaft is rotatably engaged with the housing, forming a first rotating position and a second rotating position; the power output end of the motor module is provided with a transmission module for driving the rotating shaft to rotate back and forth between the first rotating position and the second rotating position, the transmission module being in transmission engagement with the rotating shaft.
[0006] In the above-mentioned scraping massage assembly, the rotation angle of the rotating shaft ranges from ±350°; the angle between the massage head and the housing ranges from 10° to 90°.
[0007] In the above-mentioned scraping massage assembly, the side of the rotating shaft is provided with a forward branch and a reverse branch located inside the housing. The forward branch and the reverse branch are located opposite each other on both sides of the axis of the rotating shaft. The transmission module is alternately driven and engaged with the forward branch and the reverse branch to drive the rotating shaft to rotate back and forth to the first rotation position and the second rotation position.
[0008] In the above-mentioned scraping massage component, both the forward support and the reverse support are stop blocks, the transmission module is an eccentric transmission mechanism, the eccentric transmission mechanism includes a turntable coaxially arranged on the power output end of the motor module and a transmission shaft located at the edge of the turntable, the axis of the turntable and the axis of the shaft are in the same plane, the transmission shaft is located between the two stop blocks, and alternately presses the two stop blocks respectively.
[0009] In the aforementioned scraping massage assembly, a clearance distance is provided between the two stops and the turntable.
[0010] In the aforementioned scraping massage assembly, a collar is fitted onto the drive shaft, the collar being positioned between the two stops and alternately pressing the two stops respectively.
[0011] In the above-mentioned scraping massage component, both the forward support and the reverse support are semi-toothed rings, and two semi-toothed rings are connected end to end to form a toothed ring, which is sleeved on the outer surface of the rotating shaft; the transmission module is a screw drive mechanism, which includes a screw, a guide sleeve and a rack sleeved on the guide sleeve, and the rack slides in cooperation with the guide sleeve.
[0012] The lead screw is coaxially mounted on the power output end of the motor module and passes through the guide sleeve, which is connected to the motor module.
[0013] The guide sleeve has a coaxially arranged guide groove, and the rack has a guide block that passes through the guide groove. The guide block is located in the thread groove of the lead screw and slides along the thread groove of the lead screw with the guide groove. The rack is engaged with the toothed ring.
[0014] In the aforementioned scraping massage assembly, the threaded groove of the lead screw includes a bent rising section and a falling section, which are symmetrically arranged about the axis of the lead screw and are connected end to end to form a closed loop structure.
[0015] In the above-mentioned scraping massage assembly, the outer surface of the massage head is provided with protrusions; the massage head is cylindrical and is sleeved on the rotating shaft.
[0016] In the above-mentioned scraping massage component, the motor module includes a drive motor and a reducer disposed on the power output end of the drive motor, and the transmission module is disposed on the power output end of the reducer.
[0017] The beneficial effects of this utility model after adopting the above technical solution are as follows:
[0018] This technical solution places the massage head on the side of the housing, forming an L-shaped structure together. When the massage head contacts the skin, the housing moves away from the skin, preventing the hand gripping the housing from pressing on the skin, thus improving the user's operational comfort and massage experience. The massage head is connected to the housing via a rotating shaft that extends into the housing's interior. Inside the housing, the forward and reverse branches of the rotating shaft are connected to a motor module via a transmission module. The power output of the motor module rotates, driving the transmission module to alternately engage with the forward and reverse branches. When the forward branch is engaged, the rotating shaft rotates towards the side where the forward branch is located; conversely, when the reverse branch is engaged, the rotating shaft rotates towards the side where the reverse branch is located. This alternating engagement of the forward and reverse branches drives the rotating shaft to rotate back and forth, causing the massage head to scrape the skin in a reciprocating motion. This prevents the massager from tangling or tearing hair, thus avoiding damage to the skin and hair follicles, and also avoids increasing the motor load, extending the motor's lifespan.

[0027] The technical solution of this utility model will be further described in detail below with reference to specific embodiments, but this does not constitute any limitation on this utility model.
[0028] Example 1:
[0029] like Figure 1-6 As shown, the scraping massage component includes a housing 3 and a massage head 1 disposed on one side of the housing 3. A motor module is provided inside the housing 3, and a rotating shaft 2 is provided on the massage head 1. The rotating shaft 2 passes through the side of the housing 3 and extends into the interior of the housing 3. The rotating shaft 2 is rotatably engaged with the housing 3 and forms a first rotating position and a second rotating position. A transmission module 4 is provided on the power output end of the motor module for driving the rotating shaft 2 to rotate back and forth between the first rotating position and the second rotating position. The transmission module 4 is in transmission engagement with the rotating shaft 2.
[0030] In practical use, by setting the massage head 1 on the side of the housing 3, the massage head 1 and the housing 3 together form an L-shaped structure. When the massage head 1 contacts the skin, the housing 3 moves away from the skin, so that the hand holding the housing 3 avoids pressing on the skin, thus improving the user's operation rationality and massage comfort.
[0031] The side of the rotating shaft 2 is provided with a forward support 21 and a reverse support 22 located inside the housing 3. The forward support 21 and the reverse support 22 are located opposite each other on both sides of the axis of the rotating shaft 2. The transmission module 4 is in alternating transmission cooperation with the forward support 21 and the reverse support 22 to drive the rotating shaft 2 to rotate back and forth to the first rotation position and the second rotation position.
[0032] The specific operation process is as follows: the massage head 1 is connected to the housing 3 via a rotating shaft 2. The rotating shaft 2 extends into the interior of the housing 3. Inside the housing 3, the forward branch 21 and the reverse branch 22 on the rotating shaft 2 are connected to the motor module via a transmission module 4. The power output end on the motor module rotates, driving the transmission module 4 to alternately engage with the forward branch 21 and the reverse branch 22. When the rotating shaft 2 is engaged with the forward branch 21, it rotates towards the side where the forward branch 21 is located. Conversely, when the rotating shaft 2 is engaged with the reverse branch 22, it rotates towards the side where the reverse branch 22 is located. The alternating engagement of the forward branch 21 and the reverse branch 22 drives the rotating shaft 2 to rotate back and forth, thereby driving the massage head 1 to scrape the skin in a back-and-forth rotation. This avoids the scraping massager from tangling hair and tearing hair, thus preventing damage to the skin and hair follicles. At the same time, it avoids increasing the load on the motor, thereby extending the service life of the motor.
[0033] In practical applications, the motor in the motor module can be either a regular motor or a servo motor capable of rotating in both directions, also known as a forward and reverse motor. When a forward and reverse motor is used, the transmission module 4 produces two opposite actions under the drive of the forward and reverse motor, thereby alternately cooperating with the forward branch 21 and the reverse branch 22 for transmission. When a regular motor is used, a transmission module 4 capable of alternately producing two opposite actions is required, such as a crank-rocker mechanism, a crank-slider mechanism, an eccentric transmission mechanism, and a lead screw transmission mechanism, etc.
[0034] Preferably, the rotation angle of the rotating shaft 2 is within the range of ±350°; the angle between the massage head 1 and the housing 3 is within the range of 10° to 90°.
[0035] The rotation angle of the rotating shaft 2 allows the massage head 1 to have a large rotation range, reducing the frequency of high-speed scraping of the skin and avoiding discomfort caused by excessive friction. It also prevents hair from being pulled due to hair tangling. The angle between the massage head 1 and the housing 3 can be set according to actual usage needs, so that different body parts can be massaged in a normal posture, such as the armpits, back, and genitals.
[0036] like Figure 2 As shown, in some embodiments, both the forward support 21 and the reverse support 22 are stop blocks, and the transmission module 4 is an eccentric transmission mechanism. The eccentric transmission mechanism includes a turntable 41 coaxially disposed on the power output end of the motor module and a transmission shaft 43 disposed at the edge of the turntable 41. The axis of the turntable 41 and the axis of the rotating shaft 2 are in the same plane. The transmission shaft 43 is disposed between the two stop blocks and presses the two stop blocks alternately.
[0037] When the transmission module 4 adopts an eccentric transmission mechanism, the forward support 21 and the reverse support 22 adopt block structures respectively. At this time, the motor in the motor module can be selected as an ordinary motor to reduce production costs. The specific working process of the eccentric transmission mechanism is as follows: the power output end of the motor module drives the transmission shaft 43 on the turntable 41 to rotate eccentrically, so that the transmission shaft 43 generates a reciprocating displacement in the horizontal direction towards both sides. When the transmission shaft 43 moves towards one side, it pushes the forward support 21 and drives the rotating shaft 2 to rotate in the forward direction. Conversely, when the transmission shaft 43 moves towards the opposite side, it pushes the reverse support 22 and drives the rotating shaft 2 to rotate in the reverse direction. This reciprocating motion is repeated continuously to realize the reciprocating rotation of the rotating shaft 2.
[0038] As a further improvement, a clearance distance is provided between the two stops and the turntable 41.
[0039] During the swinging process of the forward support 21 and the reverse support 22 around the axis of the rotating shaft 2, a displacement is generated in the direction directly opposite to the turntable 41, which avoids the setting of the spacing and prevents the forward support 21 and the reverse support 22 from interfering with the turntable 41 due to the above displacement, thus preventing the turntable 41 from hindering the swinging of the forward support 21 and the reverse support 22.
[0040] Combination Figure 2 and Figure 3 As shown, another improvement is that a collar 42 is fitted on the drive shaft 43, and the collar 42 is located between two stops, and alternately presses the two stops respectively.
[0041] The setting of the collar 42 reduces the frictional noise between the drive shaft 43 and the forward and reverse supports 21 and 22, and buffers the high-frequency compression of the drive shaft 43 on the forward and reverse supports 21 and 22. At the same time, it avoids wear on the drive shaft 43. Whenever the collar 42 is worn or damaged, only the rubber ring needs to be replaced, making daily maintenance easy and convenient. It has the advantages of low maintenance difficulty and low cost.
[0042] Combination Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the forward support 21 and the reverse support 22 are both semi-toothed rings, and the two semi-toothed rings are connected end to end to form a toothed ring, which is sleeved on the outer side of the rotating shaft 2; the transmission module 4 is a screw drive mechanism, which includes a screw 46, a guide sleeve 45 and a rack 44 sleeved on the guide sleeve 45, and the rack 44 is slidably engaged with the guide sleeve 45.
[0043] The lead screw 46 is coaxially mounted on the power output end of the motor module and passes through the guide sleeve 45, which is connected to the motor module.
[0044] The guide sleeve 45 has a coaxially arranged guide groove 451, and the rack 44 has a guide block that passes through the guide groove 451. The guide block is located in the thread groove of the lead screw 46 and slides along the thread groove of the lead screw 46 and the guide groove 451. The rack 44 is engaged with the gear ring.
[0045] When the transmission module 4 adopts a screw drive mechanism, the forward support 21 and the reverse support 22 adopt a semi-gear ring structure respectively, and together form a gear ring mechanism. At this time, the motor in the motor module adopts a forward and reverse motor. The specific working process of the screw drive mechanism is as follows: the power output end of the motor module drives the screw 46 in the guide sleeve 45 to rotate forward and reverse. The rack 44 is provided with a collar 441 sleeved on the guide sleeve 45. The guide block is set on the inner side of the collar 441. The guide block passes through the guide groove 451 of the guide sleeve 45 and is set in the thread groove of the screw 46. Under the forward and reverse guidance of the screw 46, the guide block drives the rack 44 to reciprocate along the guide groove 451 through the collar 441. The rack 44 meshes with the gear ring, driving the gear ring to rotate forward and reverse. The rotating shaft 2 rotates synchronously with the gear ring to realize reciprocating rotation.
[0046] In some embodiments, in addition to using a lead screw drive to drive the slide block to reciprocate, a crank-slider mechanism or a cam mechanism can also be used to drive the slide block to reciprocate. This embodiment does not impose too many restrictions on this.
[0047] like Figure 6 As shown, in addition to using a forward and reverse motor in conjunction with a lead screw drive mechanism, the motor in the motor module can also be used with a regular motor. When a regular motor is selected, the thread groove on the lead screw 46 needs to adopt a non-standard structure. Specifically, the thread groove of the lead screw 46 includes a bent rising section 461 and a falling section 462. The rising section 461 and the falling section 462 are symmetrically arranged about the axis of the lead screw 46, and the rising section 461 and the falling section 462 are connected end to end to form a closed loop structure.
[0048] In practical implementation, the threaded groove of the lead screw 46 can be a standard threaded groove, where the threaded grooves extend spirally and terminate at both ends of the lead screw 46. The lead screw 46, in cooperation with the forward and reverse motor, causes the guide block to move back and forth along the threaded groove of the lead screw 46. Alternatively, the threaded groove of the lead screw 46 can be a non-standard threaded groove, and the structure of the non-standard threaded groove can take various forms. For example, the two ends of the rising section 461 extend spirally to the opposite sides of the axis of the lead screw 46, and the two ends of the descending section 462 also extend spirally to the opposite sides of the axis of the lead screw 46. When the rising section 461 and the descending section 462 are connected end to end, the middle parts of the rising section 461 and the descending section 462 intersect and connect, and the closed loop structure formed by the rising section 461 and the descending section 462 is in the shape of an "8". Or, the two ends of the rising section 461 are located on the same side of the axis of the lead screw 46, and the two ends of the descending section 462 are also located on the same side of the axis of the lead screw 46. On the same side of the axis of the lead screw 46, when the rising section 461 and the falling section 462 are connected end to end, the closed-loop structure formed by the rising section 461 and the falling section 462 is elliptical; or the two ends of the rising section 461 extend in an S-shape to the two sides of the axis of the lead screw 46, and the two ends of the falling section 462 also extend in an S-shape to the two sides of the axis of the lead screw 46. When the rising section 461 and the falling section 462 are connected end to end, the closed-loop structure formed by the rising section 461 and the falling section 462 is gourd-shaped on the radial projection plane of the lead screw 46. In addition to the above-mentioned non-standard thread groove, other non-standard thread grooves can also be used. This embodiment does not impose too many restrictions on this. If a non-standard thread groove is used for the lead screw 46, when it cooperates with a unidirectional rotating ordinary motor, the thread groove guide block can also move back and forth between the two ends of the lead screw 46, reducing the cost of motor procurement, debugging and subsequent maintenance.
[0049] In this embodiment, the lead screw 46 preferably adopts a closed-loop structure in the shape of an "8" formed by the rising section 461 and the falling section 462.
[0050] like Figure 1 As shown, preferably, the outer surface of the massage head 1 is provided with a protrusion 11; the massage head 1 is cylindrical and is sleeved on the rotating shaft 2.
[0051] In another preferred embodiment, the protrusion 11 is a raised dot, and there are several raised dots arranged sequentially along the axis of the massage head 1.
[0052] The protrusions 11 enhance the tactile sensation between the massage head 1 and the skin, increasing the physical stimulation and comfort. The protrusions 11 are preferably a series of raised dots, but they can also be a series of spaced circular, strip, or columnar textures, etc. This embodiment does not impose too many restrictions on this.
[0053] The columnar structure of the massage head 1 increases the massage contact area, better meeting the needs of different body parts. In addition, the massage head 1 can also adopt other structures such as spherical ones, but this embodiment does not impose too many restrictions on this.
[0054] In addition, the motor module includes a drive motor 6 and a reducer 5 located on the power output end of the drive motor 6, and a transmission module 4 located on the power output end of the reducer 5.
[0055] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
