Description

Massage machine core and massager

Technical Field

The utility model relates to the field of massage apparatuses, in particular to a massage machine core and a massager.

Background

The massager is a well-designed massage device, and aims to achieve the effects of promoting blood circulation and relieving muscle fatigue through a series of actions such as the action of rotating a massage head, vibration and knocking of the massage head. Especially for people who keep a fixed posture for a long time or sit for a long time, the device is certainly a very practical auxiliary tool, and helps to relieve discomfort caused by the bad habits.

The common massage machine core in the market mainly relies on the rotary motion of the massage head to massage the corresponding body part. Meanwhile, by combining with the design of the deflection structure, the kneading effect can be simulated, so that the massage experience is richer. However, this design, while unique, has a relatively limited kneading range of the kneading head. More importantly, the current design lacks a structure which can be matched with a method for massaging the shoulder and neck by pinching the shoulder and neck by a human hand, so that a certain defect exists in simulating the effect of massaging the real human hand.

In order to further enhance the massage effect and enhance the comfort of the user, the design of the massager needs to be further optimized and improved, the cost is controlled, and better use experience is brought.

In an embodiment, please refer to fig. 1-3:

Referring to fig. 1, the present application provides a massage machine core, including a motor 160 and a massage assembly 200 disposed in a housing 100; a PCB control board 150 and a battery 140 are provided in the housing 100; the PCB control board 150 is electrically connected with the motor 160, the battery 140 and the PCB lamp panel assembly 2433, respectively; the casing 100 is generally composed of a movement base 110 and a movement gland 120, and a motor mounting groove 111 for mounting a motor 160 and a mounting groove for mounting a battery 140 are arranged in the movement base 110; the mounting groove and the motor mounting groove 111 are respectively positioned at two sides of the base; as shown in fig. 1 and 3, motor mounting grooves 111 and mounting grooves are formed on two sides of the movement base 110 respectively, and the mounting grooves are arranged on the other side of the movement base 110 in close proximity to the motor mounting grooves 111, so that the motor 160 and the battery 140 can be effectively isolated, meanwhile, the battery 140 can be conveniently and directly replaced during maintenance, and the maintenance difficulty is reduced; the battery 140 is fixedly connected with the core base 110 through a battery box cover 141;

The movement gland 120 is mainly covered on the motor 160 and the gear assembly, so that the area of the movement gland 120 can be effectively reduced, the cost is saved, meanwhile, compared with a fully-wrapped top cover, the fully-wrapped top cover in the prior art is provided with a top cover which is matched with the outer contour of the movement collet 110, and when the top cover is installed, a through hole for the second massage arm 240 to pass through is required to be formed in the top cover, and therefore, when the top cover is installed, the second massage arm 240 needs to pass through the through hole in the top cover, and then the top cover is fixed with the movement collet 110; in the embodiment, when the movement gland 120 and the movement base 110 are fixedly installed, the movement gland can be directly installed without considering the influence of the second massage arm 240, so that the installation and the disassembly are easier;

The output worm of the motor 160 is meshed with a duplex worm gear 190, one end of the duplex worm gear 190 is of a worm gear structure, the other end of the duplex worm gear 190 is of a straight gear 191, the worm gear structure is meshed with the output worm, and one end of the straight gear 191 is meshed with the first gear 180; the first gear 180 is meshed with a drive gear 172 fixedly connected to the drive shaft 170; the duplex worm gear 190, the first gear 180 and the transmission gear 172 form three-stage transmission; conventional massagers typically use a two-stage drive, i.e., a structure that does not include the first gear 180, directly engaging the spur gear 191 with the drive gear 172, although a drive can also be achieved; but not facilitating the centering of the drive shaft 170, the interior space can be most effectively utilized when the drive shaft 170 is centered; however, the distance between the driving gear 172 and the duplex worm gear 190 is usually smaller due to the two-stage driving, so that it is difficult to ensure that the driving shaft 170 is just arranged in the middle, and thus the two-stage driving gears need to be increased in size to increase the distance, but the reduction ratio is poor, which is not beneficial to reasonably controlling the rotation speed of the driving shaft 170; or using a more costly and smaller brushless motor 160, which increases production costs;

two ends of the transmission shaft 170 are respectively provided with a set of massage components 200; the massage assembly 200 comprises an eccentric wheel 210 and a deflection wheel 230 which are arranged on the transmission shaft 170; the eccentric wheel 210 is in anti-rotation connection with the transmission shaft 170, specifically, a pin hole 171 is formed in the transmission shaft, and the pin hole 171 is in anti-rotation connection with the eccentric wheel 210 through a shaft piece; the eccentric wheel 210 is sleeved with a first massage arm 220; the first massage arm 220 includes a first collar 221; the first collar 221 is configured to be sleeved on the eccentric wheel 210; the first lantern ring 221 is connected with an extension arm 222, and the other end of the extension arm 222 is provided with a massage head 223; the extending arm 222 is provided with a deflection chute 224; the angle between the length direction of the deflection chute 224 and the length direction of the extension arm 222 is 20-45 degrees;

in one embodiment, the angle between the length direction of the swing chute 224 and the length direction of the extension arm 222 is 30 °;

In one embodiment, the angle between the length direction of the swing chute 224 and the length direction of the extension arm 222 is 20 °;

In one embodiment, the angle between the length direction of the swing chute 224 and the length direction of the extension arm 222 is 40 °;

When the included angle between the length direction of the deflection sliding chute 224 and the length direction of the extension arm 222 is larger, although the fluctuation height difference of the massage head 223 can be increased, the smoothness of the cooperation sliding of the deflection sliding chute 224 and the pin 130 is affected, so that the preferred angle is 20-45 degrees, and smooth movement can be ensured and better fluctuation height is also provided;

The deflection chute 224 is matched with a pin 130 arranged on the shell 100, and the pin 130 is fixedly arranged on the shell 100; therefore, when the transmission shaft 170 rotates, the massage head 223 makes a reciprocating and undulating composite motion, and as illustrated in fig. 1, the undulation refers to the up-down direction in fig. 1, and by setting the included angle between the deflection chute 224 and the extending direction of the first massage arm 220, the undulating distance of the massage head 223 during movement can be increased, so as to improve the massage effect; the extending direction of the first massage arm 220 is also the length direction of the extension arm 222;

In the prior art massager, the deflection sliding groove 224 is generally consistent with the length direction of the extension arm 222, that is, the two are parallel, when the eccentric wheel 210 works, the deflection distance of the massage head 223 is determined by the eccentric distance of the eccentric wheel 210, so that the deflection distance of the massage head 223 is smaller, the release of the massage force is insufficient, mainly because the second massage arm 240 is mainly in contact with the shoulder neck/back, when the deflection height of the massage head 223 is smaller, the massage force cannot be applied in deeper contact with the body, particularly when the massage head is applied to the shoulder neck, the heating massage head 243 of the second massage arm 240 can basically form a more stable contact support with the neck, the deflection of the heating massage head 243 can have an inward clamping effect, so that the effect of the heating massage head 243 can be stable when the neck is clamped, and if the massage head 223 only has a smaller deflection height, the pressing effect of the shoulder 223 is poor, the massage experience is more biased to slightly press back and forth at the shoulder, and the massage experience is reduced; in the embodiment, by setting the included angle, the undulating distance of the massage head 223 can be effectively enlarged, so that a better reciprocating pressing effect from shallow to deep is achieved on the shoulder, and better massage experience is realized;

In one embodiment, the massage head 223 has an arc surface and protrudes toward the second massage arm 240; by protruding in the direction of the second massage arm 240, it is possible to better conform to the shoulder/neck/back curve of the human body during massage.

The deflection wheel 230 comprises a clamping block 231 and a connecting column 232 which are arranged at an included angle; the connecting column 232 is eccentric and is obliquely connected with the transmission shaft 170, specifically, a through hole which allows the transmission shaft 170 to pass through is arranged in the connecting column 232; the clamping block 231 is in anti-rotation connection with the eccentric wheel 210, specifically, a bump 211 is arranged on one side of the eccentric wheel 210, which is close to the eccentric wheel 230; the protruding block 211 is eccentrically arranged, and the clamping block 231 is provided with a groove matched with the protruding block 211 so as to realize the rotation stopping connection of the clamping block 231 and the eccentric wheel 210; the connecting column 232 is sleeved with a second massage arm 240, and a heating massage head 243 of the second massage arm 240 is internally provided with a PCB lamp panel assembly 2433 for heating; a ball 244 is disposed on the opposite side of the second massage arm 240 to the heating massage head 243, and a ball chute 113 for sliding the ball 244 is disposed on the housing 100; the PCB light panel assembly 2433 can realize heating by utilizing light emission, and when the light panel cover 2432 is transparent, it has a certain light effect; the PCB lamp panel assembly 2433 heats by utilizing luminescence, so that the heating uniformity and the installation convenience are improved; in the prior art, heating is usually realized through a heating plate, but the heating plate has certain requirements on a mounting surface, and the heating plate is usually required to be mounted close to the heating surface to have a good heating effect, so that the heating plate is usually arranged on a flat mounting surface, and the heating effect is poor when the massage head with an arc-shaped structure is not suitable to be mounted; the PCB lamp panel assembly 2433 can well solve the problem, ensures the heating uniformity and is convenient to install;

In an embodiment, the cross-sectional area of the clamping block 231 is larger than the area of the central hole of the first collar 221 on the first massage arm 220 to limit the first massage arm 220; a deflection wheel gland 250 for limiting the second massage arm 240 to prevent slipping off the connecting column 232 is fixedly connected to the outer side of the connecting column 232;

In one embodiment, the second massage arm 240 includes a second collar 241 for engaging the post 232; the second collar 241 is connected with a heating massage head 243 through a connecting arm 242; the heating massage head 243 comprises a housing 2431 connected with the connecting arm 242, and a lamp panel cover 2432 is fixedly connected to the housing 2431; the housing 2431 and the lamp panel cover 2432 form a containing space for installing the PCB lamp panel assembly 2433; a ball head 244 is arranged on the other side of the second lantern ring 241 opposite to the heating massage head 243; the ball head sliding groove 113 is arranged on the core collet 110; the length extending direction of the ball sliding groove 113 is parallel to the length direction of the pin 130, so that the reciprocating direction of the second massage arm 240 is spatially perpendicular to the reciprocating direction of the first massage arm 220.
