Description

Technical Field

[0001] This utility model relates to the field of massagers, and in particular to a handheld kneading massager. Background Technology

[0002] Back scratchers are a common type of back massage tool. Since itchy backs are often difficult to touch directly with the hands, most people use back scratchers to rub the itchy areas. The main structure of a back scratcher consists of a handle and scratching claws attached to the handle. When using it, you hold the handle and swing it back and forth, causing the scratching claws to rub the itchy area. However, swinging the arm back and forth in a bent position is not ergonomic and can easily lead to fatigue and soreness in the arms and elbows over time. Therefore, most back massagers currently used are electric. These electric back massagers replace the back-swinging motion of the arms with the vibration and extension of their massage heads. While rubbing the back, they also reduce hand movements, thus reducing the difficulty of use and the fatigue of operation. However, when the massage head of the back massager is pressed against the back, it will generate a lot of static friction with the skin. Especially when the outer layer of the massage head is made of a material with high friction resistance, such as rubber, it is easy for the massage head and the skin to be in a relatively static state. However, when the massage head cannot extend and retract normally, since the back massager is still working normally, in order to maintain the relative movement of the massage head and the shell, the shell of the back massager will extend and retract relative to the massage head, thus affecting the control of the arm and the difficulty of operation. Utility Model Content

[0003] The purpose of this invention is to provide a handheld kneading massager that avoids relative displacement between the massage part and the shell of the back-scratching massager, thereby reducing the arm's control force and the difficulty of operation.

[0010] In the aforementioned handheld kneading massager, the first transmission mechanism is a lead screw transmission mechanism. The lead screw transmission mechanism includes a lead screw coaxially connected to the first drive module and a guide sleeve sleeved on the lead screw. The guide sleeve is fixedly connected to the first drive module. The guide sleeve has a guide groove extending axially. The first massage rod is sleeved on the guide sleeve and slides with the guide sleeve. The first massage rod has a guide portion that passes through the guide groove and is engaged with the threaded groove of the lead screw.

[0011] In the aforementioned handheld kneading massager, 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 connected end to end to form a closed loop structure.

[0012] In the aforementioned handheld kneading massager, both the first and second massage rods are provided with guide bars, and the housing is provided with guide grooves corresponding to the two guide bars one by one. The guide bars are disposed in the corresponding guide grooves and slide in cooperation with the corresponding guide grooves.

[0013] In the aforementioned handheld kneading massager, the transmission component is a rotating shaft that rotatably engages with the housing;

[0014] The first massage rod is provided with a drive transmission structure, which includes a drive turntable and a second connecting groove formed on the first massage rod. The second connecting groove intersects the axis of the first massage rod. A second connecting post is provided at the edge of the drive turntable. The second connecting post is movably arranged relative to the second connecting groove. The power output end of the drive assembly is connected to the drive turntable. The drive turntable is coaxially connected to the rotating shaft.

[0015] The second massage rod is provided with a driven transmission structure, which includes a driven turntable and a third connecting groove formed on the second massage rod. The third connecting groove intersects the axis of the second massage rod. A third connecting post is provided at the edge of the driven turntable. The third connecting post is movably arranged relative to the third connecting groove and is circumferentially offset from the second connecting post around the rotating shaft. The driven turntable is coaxial with the rotating shaft.

[0016] In the aforementioned handheld kneading massager, the driving component is a second driving unit. The second driving unit includes a second driving module and a second transmission mechanism. The second transmission mechanism includes an active bevel gear disposed on the power output end of the second driving module and a driven bevel gear coaxially disposed on the driving turntable.

[0021] The beneficial effects of this utility model after adopting the above technical solution are as follows:

[0022] This technical solution utilizes two massage rods, designated as a first massage rod and a second massage rod. Driven by the same mechanical transmission component, the first and second massage rods move synchronously in opposite directions. Specifically, when the first massage rod extends forward, it drives the second massage rod to retract backward via a transmission component; conversely, when the first massage rod retracts backward, it drives the second massage rod to extend forward via the transmission component. A first massage part is fixed to the first massage rod, and a second massage part is fixed to the second massage rod. Both massage parts are designed to simultaneously adhere to the skin. When both massage parts are relatively stationary due to friction, the first massage part pushes away from the housing via the first massage rod, while the second massage part pulls the housing closer via the second massage rod. The interaction between the pushing and pulling of the first and second massage parts achieves a force balance, resulting in a net force of zero on the housing. When the net force is zero, there is no force pushing the housing relative to the massage parts, thus preventing relative displacement between the massage parts and the housing, reducing the arm's control effort and operational difficulty.

[0043] 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.

[0044] Example 1:

[0045] like Figure 1-7 As shown, a handheld kneading massager includes a housing 1. The housing 1 is provided with a first massage rod 7 that slides with the housing 1 and a drive assembly for driving the first massage rod 7 to extend and retract. The drive assembly is connected to the first massage rod 7. The first massage rod 7 is provided with a first massage part 5. The housing 1 is also provided with a second massage rod 2 that slides with the housing 1 and a transmission member 6 for driving the second massage rod 2 to extend and retract relative to the first massage rod 7. The transmission member 6 is located between the second massage rod 2 and the first massage rod 7 and is connected to the second massage rod 2 and the first massage rod 7 respectively. The second massage rod 2 is provided with a second massage part 3. The second massage part 3 and the first massage part 5 are located on the same side of the housing 1 for synchronous kneading of the body.

[0046] The specific working principle is as follows: Two massage rods, namely the first massage rod 7 and the second massage rod 2, move synchronously and in opposite directions under the mechanical transmission of the same drive component. Specifically, when the first massage rod 7 extends forward on the housing 1, it drives the second massage rod 2 to retract backward on the housing 1 via the transmission component 6; conversely, when the first massage rod 7 retracts backward on the housing 1, it drives the second massage rod 2 to extend forward on the housing 1 via the transmission component 6. A first massage part 5 is fixed to the first massage rod 7, and a second massage part 3 is fixed to the second massage rod 2. The first massage part 5 and the second massage part 3... The massage part 3 is used to simultaneously adhere to the skin. When both the first massage part 5 and the second massage part 3 are relatively stationary with respect to the skin due to friction, the first massage part 5 will push away from the housing 1 through the first massage rod 7, and the second massage part 3 will pull the housing 1 closer through the second massage rod 2. Under the interaction of the pushing away of the first massage part 5 and the pulling closer of the second massage part 3, the housing 1 achieves a balance of forces, that is, the resultant force of the housing 1 is zero. When the resultant force of the housing 1 is zero, there is no force to push the housing 1 to move relative to the massage part, thereby avoiding relative displacement between the massage part of the back-scratching massage tool and the housing 1, thus reducing the arm control force and the difficulty of operation.

[0047] Combination Figure 2 and Figure 3 As shown, preferably, the transmission component 6 is a gear, the shaft of the gear is rotatably engaged with the housing 1, and the gear is meshed with the first massage rod 7 and the second massage rod 2 respectively.

[0048] When the transmission component 6 is preferably configured as a gear, the first massage rod 7 and the second massage rod 2 are both rack and pinion structures, and the gear is engaged with the teeth of the first massage rod 7 and the second massage rod 2 respectively.

[0049] In some embodiments, the transmission component 6 is a lever, with the middle part of the lever hinged to the housing 1, and the two ends of the lever hinged to the first massage rod 7 and the second massage rod 2, respectively.

[0050] In practical use, the transmission component 6 can be configured as a gear or a lever. This embodiment does not impose too many restrictions on this. When the transmission component 6 is configured as a lever, the middle part of the lever is hinged to the housing 1, and the two ends of the lever are respectively hinged to the first massage rod 7 and the second massage rod 2.

[0051] Combination Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the specific structure of the drive component is as follows: the drive component is a first drive unit, which includes a first drive module 9 and a first transmission mechanism 8 disposed on the housing 1. The first massage rod 7, the first transmission mechanism 8 and the first drive module 9 are connected in sequence.

[0052] In this embodiment, the mechanical transmission method by which the first driving unit drives the first massage rod 7 to reciprocate and extend can be either the first driving module 9 in combination with the crank sliding mechanism, the first driving module 9 in combination with the lead screw transmission mechanism, or the first driving module 9 in combination with the cam mechanism, etc. This embodiment does not impose too many restrictions on this.

[0053] The first drive module 9 includes a first motor and a first reducer connected to the power output end of the first motor. The power output end of the first reducer is connected to the first transmission mechanism 8.

[0054] In some embodiments, the first transmission mechanism 8 is a crank-slider mechanism, which includes a transmission module and a crank disc 802 that rotates with the housing 1. The crank disc 802, the transmission module, and the first drive module 9 are connected in sequence. A first connecting post 801 is provided at the edge of the crank disc 802. A first connecting groove 702 is provided on the first massage rod 7. The first connecting post 801 is located in the first connecting groove 702 and is relatively movable relative to the first connecting groove 702.

[0055] The first connecting post 801 rotates and engages with the first connecting groove 702 along its circumference and slides along the length of the first connecting groove 702; the first connecting groove 702 intersects the axis of the first massage rod 7.

[0056] Combination Figure 3 and Figure 4As shown, the specific structure of the transmission module is as follows: the transmission module includes a first bevel gear 804, a second bevel gear 803, and a crank disk 802, all of which are rotatably engaged with the housing 1. The first bevel gear 804 is fixedly connected to the first drive module 9 and meshes with the second bevel gear 803. The second bevel gear 803 is provided with a first transmission gear part 80301 coaxially connected, and the crank disk 802 is provided with a second transmission gear part 80201 coaxially connected. The second transmission gear part 80201 meshes with the first transmission gear part 80301.

[0057] Combination Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the first transmission mechanism 8 is a lead screw transmission mechanism, which includes a lead screw 806 coaxially connected to the first drive module 9 and a guide sleeve 805 sleeved on the lead screw 806. The guide sleeve 805 is fixedly connected to the first drive module 9. A guide groove 101 extending axially is provided on the guide sleeve 805. The first massage rod 7 is sleeved on the guide sleeve 805 and slides with the guide sleeve 805. A guide part 704 is provided on the first massage rod 7. The guide part 704 passes through the guide groove 101 and is engaged with the threaded groove of the lead screw 806.

[0058] like Figure 6 As shown, preferably, the threaded groove of the lead screw 806 includes a bent rising section 8061 and a falling section 8062, which are symmetrically arranged about the axis of the lead screw 806 and connected end to end to form a closed loop structure.

[0059] In practical implementation, the threaded groove of the lead screw 806 can be a standard threaded groove, where the threaded grooves extend spirally and terminate at both ends of the lead screw 806. The lead screw 806, in cooperation with the forward and reverse motor, causes the guide 704 to move back and forth along the threaded groove of the lead screw 806. Alternatively, the threaded groove of the lead screw 806 can be a non-standard threaded groove, which has various structural forms. For example, the opposite ends of the rising section 8061 extend spirally to opposite sides of the axis of the lead screw 806, and the opposite ends of the descending section 8062 also extend spirally to opposite sides of the axis of the lead screw 806. When the rising section 8061 and the descending section 8062 are connected end to end, their middle parts intersect and connect. The closed-loop structure formed by the two sections is shaped like an "8"; or the two ends of the rising section 8061 are located on the same side of the axis of the lead screw 806, and the two ends of the falling section 8062 are also located on the same side of the axis of the lead screw 806. When the rising section 8061 and the falling section 8062 are connected end to end, the closed-loop structure formed by the rising section 8061 and the falling section 8062 is elliptical; or the two ends of the rising section 8061 extend in an S-shape to the two sides of the axis of the lead screw 806, and the two ends of the falling section 8062 also extend in an S-shape to the two sides of the axis of the lead screw 806. When the rising section 8061 and the falling section 8062 are connected end to end, the closed-loop structure formed by the rising section 8061 and the falling section 8062 is gourd-shaped on the radial projection plane of the lead screw 806. In addition to the above-mentioned non-standard thread grooves, other non-standard thread grooves can also be used, and this embodiment does not impose too many restrictions on them. If a non-standard threaded groove lead screw 806 is used, when working with a unidirectional rotating ordinary motor, the threaded groove guide 704 can move back and forth between the two ends of the lead screw 806, reducing the cost of motor procurement, debugging and subsequent maintenance.

[0060] Another preferred embodiment uses a lead screw 806 with a closed-loop structure formed by the rising section 8061 and the falling section 8062, which is shaped like the number "8".

[0061] like Figure 1 As shown, the specific way in which the first massage rod 7 and the second massage rod 2 are coupled with the housing 1 is as follows: both the first massage rod 7 and the second massage rod 2 are provided with guide strips, and the housing 1 is provided with guide grooves 101 that correspond one-to-one with the two guide strips. The guide strips are located in the corresponding guide grooves 101 and slide in cooperation with the corresponding guide grooves 101.

[0062] like Figure 2 As shown, the guide bar on the first massage bar 7 is the first guide bar 701, and the guide bar on the second massage bar 2 is the second guide bar 201.

[0063] like Figure 8 and 9As shown, in some embodiments, the transmission component 6 is a rotating shaft that rotatably engages with the housing 1;

[0064] The first massage rod 7 is provided with a drive transmission structure 12, which includes a drive turntable 1201 and a second connecting groove 1202 opened on the first massage rod 7. The second connecting groove 1202 intersects the axis of the first massage rod 7. A second connecting post 1203 is provided at the edge of the drive turntable 1201. The second connecting post 1203 and the second connecting groove 1202 are movably arranged relative to each other. The power output end of the drive component is connected to the drive turntable 1201. The drive turntable 1201 is coaxially connected to the rotating shaft.

[0065] The second massage rod 2 is provided with a driven transmission structure 13, which includes a driven turntable 1301 and a third connecting groove 1303 formed on the second massage rod 2. The third connecting groove 1303 intersects the axis of the second massage rod 2. A third connecting post 1302 is provided at the edge of the driven turntable 1301. The third connecting post 1302 is movably arranged relative to the third connecting groove 1303 and is circumferentially offset from the second connecting post 1203 around the axis of rotation. The driven turntable 1301 is coaxial with the axis of rotation.

[0066] The second connecting post 1203 is rotatably engaged with the second connecting groove 1202 along its circumference and is slidably engaged along the length of the second connecting groove 1202; the third connecting post 1302 is rotatably engaged with the third connecting groove 1303 along its circumference and is slidably engaged along the length of the third connecting groove 1303.

[0067] In the embodiment where a rotating shaft is used as a transmission component, the drive assembly is a second drive unit. The second drive unit includes a second drive module 10 and a second transmission mechanism 11. The second transmission mechanism 11 includes an active bevel gear 1101 disposed on the power output end of the second drive module 10 and a driven bevel gear 1102 coaxially disposed on the drive turntable 1201. The driven bevel gear 1102 is meshed with the active bevel gear 1101.

[0068] In some transmission implementations, the second transmission mechanism 11 can drive the rotating shaft to rotate not only by gear transmission with gear meshing, but also by belt transmission, chain transmission, friction transmission or coupling transmission. This embodiment does not impose too many restrictions on this.

[0069] In a specific configuration, the second drive module 10 includes a second motor and a second reducer located on the power output end of the second motor. The power output end of the second reducer is connected to the active bevel gear 1101.

[0070] Combination Figure 8 and Figure 9As shown, it also includes a flexible sleeve 15, which includes a hollow body 1501 and two telescopic ends 1502 connected to the body 1501. The housing is located inside the body 1501. The first massage rod 7 and the first massage part 5 are both located inside one of the telescopic ends 1502, and the second massage rod 2 and the second massage part 3 are both located inside the other telescopic end 1502.

[0071] The flexible sleeve 15 provides a soft touch to all parts of the outer surface of the massager. The body 1501 of the flexible sleeve 15 improves the comfort of holding the shell and increases the resistance to slipping off the hand to prevent the massager from falling. The telescopic end 1502 of the flexible sleeve 15 improves the comfort of the first massage part 5 and the second massage part 3 in contact with the massage area.

[0072] like Figure 9 As shown, preferably, at least one telescopic end 1502 is fixed with a vibration motor 14.

[0073] The installation of the vibration motor 14 enables the telescopic end 1502 of the flexible sleeve 15 to have a vibration effect. In actual use, in addition to reciprocating and rubbing the massage area under the drive of the first massage rod 7 and the second massage rod 2, the telescopic end 1502 also vibrates and massages the massage area through the vibration motor 14, thereby producing a multi-layered massage sensation to improve the massage effect and tactile comfort.

[0074] In practical applications, the vibration motor 14 can be set as a single motor or as two motors. When one vibration motor 14 is set, the vibration motor 14 is installed in one of the telescopic ends 1502. When two vibration motors 14 are set, the two vibration motors 14 correspond one-to-one with the two telescopic ends 1502, and the vibration motors 14 are installed in the corresponding telescopic ends 1502.

[0075] Combination Figure 8 and Figure 9 As shown, in another preferred embodiment, at least one telescopic end 1502 is provided with a corrugated deformation portion 15021.

[0076] The corrugated deformation section 15021 is specifically a flexible corrugated tube structure. The corrugated deformation section 15021 enables the telescopic end 1502 to enhance the deformation of elongation and shortening through the corrugated deformation section 15021, thereby increasing the telescopic range of movement of the telescopic end 1502, and thus indirectly increasing the kneading range of the massager, thereby improving the massage efficiency.

[0077] In practical applications, the corrugated deformation part 15021 can be provided on one telescopic end 1502 or on two telescopic ends 1502. This embodiment does not impose too many restrictions on this.

[0078] like Figure 3As shown, as a further improvement of this embodiment, it also includes a guide portion 4, a first massage portion 5 and a second massage portion 3, both of which are disposed between the guide portion 4 and the housing 1, and a first massage rod 7 and a second massage rod 2, both of which are inserted into the guide portion 4 and slide in cooperation with the guide portion 4.

[0079] The first massage rod 7 and the second massage rod 2 are both inserted into the guide part 4, so that when the first massage rod 7 and the second massage rod 2 move telescopically, in addition to slidingly engaging with the housing 1, they also slidely engage with the guide part 4. The guide part 4 and the housing 1 together limit the movement at both ends of the two massage rods, so as to avoid the first massage part 5 and the second massage part 3 from interfering with each other and affecting normal movement due to the shaking of the first massage rod 7 and the second massage rod 2 during telescopic movement.

[0080] Combination Figure 1 and Figure 2 As shown, in the specific configuration, the first massage rod 7 includes a first massage rod body and a first guide bar 703. The first massage rod body is connected to the drive assembly (i.e., the first drive unit) and slides with the housing 1. The transmission component 6 is connected to the first massage rod body. The first massage rod 7, the first massage part 5 and the first guide bar 703 are connected in sequence.

[0081] In addition, the second massage rod 2 includes a second massage rod body and a second guide bar 202. The second massage rod body is connected to the transmission component 6 and slides with the housing 1. The second massage rod 2, the second massage part 3 and the second guide bar 202 are connected in sequence.

[0082] The first guide strip 703 is preferably an I-shaped profile, which gives it good strength and thus good stability. Alternatively, a cross-shaped profile or a straight profile can be used as a replacement. Similarly, the second guide strip 202 is preferably an I-shaped profile, but a cross-shaped profile or a straight profile can also be used as a replacement. This embodiment does not impose excessive restrictions on the specific structure of the first guide strip 703 and the second guide strip 202.

[0083] Combination Figure 2 and Figure 3 As shown, both the first massage unit 5 and the second massage unit 3 are equipped with vibration motors, so that in addition to rubbing the skin by telescopic movement, the first massage unit 5 and the second massage unit 3 also massage the skin by vibration; wherein, the vibration motor in the first massage unit 5 is the first vibration motor 503, and the vibration motor in the second massage unit 3 is the second vibration motor 303.

[0084] In this embodiment, the first massage part 5 includes a first massage ball 501 and a first connecting block 502 connected to the first massage ball 501. The first connecting block 502 is fixedly connected to the first massage rod 7. Specifically, the first connecting block 502 is connected to the first massage rod body and the first guide bar 703 respectively.
