Safety foot massage machine

The present invention relates to a massager, in particular a safety foot massage machine.

At present, there are a large variety of foot massagers on the market, and the techniques of the major manufacturers for the foot massager are mainly focused on improving the massage effect. As people's requirements for quality of life are getting higher and higher, consumers have more and more functional requirements for foot massagers, which makes the foot massager more and more multifunctional and intelligent. A versatile foot massager is connected to our home's 220 volts, and in order to achieve a variety of functions, it also has a complex circuit board inside. In the current technology, there are few studies on the design or improvement of the electrical safety of the foot massager, and more on the structure of the massage element or the structure of the massage machine. For example, the patent for the foot massage device, the Chinese patent number is 201320376058.7, the patent describes in the specification the massage mechanism of the massage device and related electrical components such as air pump, drive motor, gas valve, etc., but are not disclosed in use. How to protect these electrical components and how to solve the dangerous problem of touching the power supply during the user's use.

The foot massager is mainly used to stimulate the acupuncture points of the foot to stimulate the acupuncture points, soothe the muscles and the like to relax the fatigue and relax the body, so that the consumers are loved. In the massage effect, the roller type foot massager with the Chinese patent number 201120224284.4 proposed a better massage plan, which solved the problem of small massage area and single massage on the massage machine. The utility model adopts the following scheme: a driving motor, a worm gear mechanism, a front roller massaging component, a middle roller massaging component and a rear roller massaging component are mounted on the base of the mechanism, wherein the output end of the worm gear mechanism is connected to the middle transmission shaft. The middle drive shaft is mounted with a middle roller massage member, a first pulley assembly and a second pulley assembly. The first pulley assembly is coupled to the front drive shaft, the second pulley assembly is coupled to the rear drive shaft, and the front roller massage member is mounted On the front drive shaft, the rear roller massage member is mounted on the rear drive shaft. Although the above structure uses a three-stage massage to solve the problem of small and single area of the traditional massage machine massage, there are still deficiencies. Since all the massage points on the same circumference of the roller massage member are the same, the massage of each massage point to the foot is the same when the user uses the device, and the effect of stimulating the acupuncture points is not achieved.

The present invention provides a safe foot massage machine which solves the problem of poor electrical safety, complicated structure and poor massage effect of the foot massager in the background art. This creation solves the technical solutions adopted by its technical problems.

A safety foot massage machine comprises an electric control device, a base and a protective cover, wherein the base is provided with two sets of massage mechanisms, each set of massage mechanism comprises at least a toe massage device and a heel massage device; the protective cover is arranged at The power control device includes a power circuit board and a control circuit board, wherein the power circuit board and the control circuit board are respectively installed at front and rear ends of the massage mechanism, and the protection cover is provided with a support foot The annular support platform of the portion is provided with a slot for contacting the massage mechanism with the foot in the middle of the support base, and a baffle for blocking the contact between the foot and the power circuit board is disposed between the power circuit board and the slot.

In order to solve the problems of the background art, in addition to the above technical solutions, the following improvement is also included: as an improvement, the electronic control device includes a relay, and the relay is mounted on On the base, the base is provided with a water retaining rib located around the relay, and the relay is connected with the control circuit board. A power component is provided on the power circuit board, such as a MOS switch tube. The power circuit board is provided with an L-shaped metal plate for dissipating heat from a high-power component, and the L-shaped metal plate is provided with a heat-insulating sleeve for preventing scalding of adjacent components.

As an improved solution, the massage mechanism comprises a driving mechanism, a toe massage device, a foot massage device and a heel massage device. The toe massage device comprises a roller massage device, the foot massage device comprises a sliding massage plate, and the heel massage device comprises a massage column. The sliding roller massage member is provided with an eccentric wheel, and the driving mechanism drives the sliding roller massage member to rotate, and the foot massage device is linked with the roller massage member through the eccentric wheel, and the heel massage device is linked with the foot massage device. The toe massage device comprises a roller massage component, and the roller massage component has at least one set of massage heads, each set of massage head comprises a first massage head with a soothing massage surface and a second massage head with an impact massage surface, soothing the massage surface slope The angle is smaller than the slope angle of the impact massage surface, and the soothing massage surface is arranged in the same direction as the impact massage surface. During the massage, the sole of the person transitions from the soothing massage surface of one massage head to the impact massage surface of the other massage head, thereby generating a strong stimulation.

As an improved solution, the massage mechanism further comprises a foot massage device, the foot massage device comprises a slide massage member and a limit shaft, the base is provided with a support seat, the support seat is provided with a mounting groove, and the two ends of the limit shaft are installed at In the above mounting groove, the outer end portion of the limiting shaft is locked in the mounting groove by a screw. The distance between the inner end of the limiting shaft and the adjacent electrical appliance is less than 15 mm. The protective cover is provided with a pressure limiting block that presses the inner end portion. An annular reinforcing rib is arranged on the inner side of the slot of the support platform, and the annular reinforcing rib extends toward the base, and the above-mentioned pressure limiting block is disposed on the annular reinforcing rib.

Compared with the background art, the technical solution has the following advantages: 1. When the foot reaches the foot massager, the front end of the toe portion is a power circuit board, and there is dangerous high pressure, and the massage machine The roller massage member, the massage plate and the massage column should be extended to contact the person's foot. In this way, the power circuit board may come into contact with external objects or liquids, thereby causing danger or damage to the circuit board circuit. To this end, a baffle is placed adjacent to the power circuit board on the protective cover to separate the potential contact between the power circuit board and the outside to ensure the safety of the foot massager.

2. By separating the relay from the control board, the effect of the relay on the electronic components on the control board is reduced. At the same time, the separation of the relay from the control circuit board is beneficial to reduce the height of the control circuit board, thereby reducing the overall volume of the foot massager and making the foot massager more compact. The relay is placed on the base and has water-blocking ribs around it. When a small amount of water enters the inside of the foot massage machine, it can prevent the relay from coming into contact with water and damage the relay.

3. The traditional massage foot machine has a plurality of massage heads distributed on the roller massage parts, each of which has the same shape, so that when the user's sole is massaged, the feeling of passing each massage head is the same. Therefore, it is not very good to stimulate people's acupuncture points. The roller massage piece of the present invention has at least one set of massage heads, each set of massage head includes a first massage head with a soothing massage surface and a second massage head with an impact massage surface, and the impact massage surface is in the same direction as the soothing massage surface Settings. When the massage head massages the user's sole, the midsole will first pass through the soothing massage surface, and then suddenly transition to the impact massage surface, giving the user a distinct impact. The slope of the impact massage surface is larger than the slope of the soothing massage surface, so that the massage effect is more remarkable.

4. In modern life, people want to miniaturize household items, so the size of the massage machine is also required to be miniaturized. The massage foot machine includes massage components and devices inside. The miniaturization will inevitably compress the space of each functional component. At this time, we need to arrange the position of each electronic control component more reasonably to ensure safety. By letting the motor have two sets of massage mechanisms in the middle, the product structure is more compact, and the motor has strong electric power. The limit shaft of the foot massage device is close to the motor. Within 15mm, if it is fixed by screws like the traditional design, it is likely that the space is not enough. Even if the space is enough, the safety clearance of the electric appliance cannot reach the safety distance standard. Therefore, a pressure limiting block is arranged on the protective cover, and the pressure limiting block is a plastic part. Let the pressure limiting block catch the inner end of the limiting shaft, thereby avoiding the safety gap problem of the above electrical appliances and solving the problem of insufficient space.
