Description

Massaging device

Technical Field

The present utility model relates to a massage device, and more particularly, to a multifunctional massage device providing a massage effect by electric pulses.

Background

A large number of workers work by using computers, which easily leads to strain on the waist and neck. In addition, since the mouse is used for a long time, a light person causes fatigue of the wrist, and serious occupational diseases such as a mouse elbow and the like may be caused. Accordingly, various kinds of massagers have been developed. Early wrist massagers provided a massaging action by way of mechanical vibration, however such massagers were complex in construction, bulky and disadvantageous for working while massaging. Thereafter, there have been massage apparatuses for stimulating skin and muscle by applying electric pulses using needle electrodes to provide acupuncture effects, and some of these massage apparatuses additionally have a heating function. However, the structure and design of these massagers in the prior art are not reasonable, resulting in frequent occurrence of various discomforts for users during use and poor portability.

Detailed Description

Exemplary embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

Fig. 1 and 2 illustrate a massager 100 according to an exemplary embodiment of the present utility model, which includes: a housing; an electrode pad 101 exposed to the surface of the case for contact with the skin; a circuit board 107 disposed within the housing, the circuit board 107 having a control circuit thereon, the control circuit being electrically connected to the electrode pads 101 and configured to apply an electrical pulse to the electrode pads 101 upon activation of the massager 100; and a heating sheet 102, wherein the heating sheet 102 is attached to the inner side of the electrode sheet 101 and is configured to heat the electrode sheet 101 under the control of a control circuit.

In the illustrated embodiment, the housing is comprised of an upper housing component 105 and a lower housing component 111. It will be appreciated by those skilled in the art that the housing of the present utility model may also have different configurations, or a different number of housing member compositions. Furthermore, while two electrode pads 101 and two heating pads 102 are shown in the illustrated embodiment, it will be appreciated by those skilled in the art that the number of electrode pads and heating pads may be set as desired, and may be one or more.

In an exemplary embodiment, a flexible pad 103 made of a flexible material may be provided on the upper housing part 105. The electrode sheet 101 and the heating sheet 102 are supported by a flexible pad 103. In an exemplary embodiment, the flexible pad 103 may be made of a more flexible, resilient material (e.g., silicone, etc.). Since the flexible pad 103 is deformed when being subjected to external pressure, the shape thereof is more fitted to the skin of the human body, so that the massager 100 can be adapted to massage various parts of the human body, such as the neck, waist, back, wrist, leg, etc. In a preferred embodiment, a bracket 104 may also be provided on the upper housing part 105, said flexible pad 103 being at least partially supported by the bracket 104. In this way, the space of the flexible pad 103 that deforms when subjected to a force will be further increased, further improving the fit of the massager to various parts of the human body. In a further preferred embodiment, the bracket 104 may be a resilient bracket.

In use, a user can attach the face of the massager 100 provided with the electrode pads to a portion of the body to be massaged. After the massager is started, the electrode plate 101 can continuously or intermittently release electric pulses to the skin part, so that the massaging effect of muscles at the part is realized. Meanwhile, the heating plate 102 heats the electrode plate 101, and then the electrode plate 101 heats the massaged part of the skin, so that the blood circulation is promoted, and the muscle fatigue is relieved. The heating plate is attached to the inner side of the electrode plate, so that the temperature of the electrode plate can be quickly increased along with the increase of the temperature of the heating plate, and the electrode plate can be heated at the skin part while discharging pulse to the skin part, so that extra space is not required to be reserved for the heating device on the surface of the massager, which is contacted with the skin, and the electrode plate can be made to be larger in size and can be heated more uniformly.

In a preferred embodiment, the heating sheet 102 may be the same or substantially the same size and shape as the electrode sheet 101, and may be adhered to the inner surface of the electrode sheet 101 by thermally conductive adhesive so as to enable more uniform heating of the electrode sheet 101.

According to an exemplary embodiment, the massager 100 may further comprise a temperature sensor 116, the temperature sensor 116 being configured to sense the temperature of the electrode sheet 101. The temperature sensor 116 may continuously sense the temperature of the electrode sheet 101 and send information to the control circuit, and when the temperature is lower than a predetermined temperature, the control circuit may control the heat-generating sheet 102 to continuously generate heat; when the temperature is higher than the preset temperature, the control circuit can control the heating sheet 102 to stop heating, so that skin scald or discomfort caused by overhigh temperature of the electrode sheet 101 is avoided.

In an exemplary embodiment, the temperature sensor 116 may include a probe (e.g., a Negative Temperature Coefficient (NTC) temperature measuring head) in contact with the electrode pad 101 or the electric heating pad 102, may directly sense the temperature of the electrode pad 101, or may indirectly sense the temperature of the electrode pad 101 by sensing the temperature of the heating pad 102.

According to an exemplary embodiment, the massager 100 may further include a skin humidity sensor 115, the skin humidity sensor 115 configured to detect the humidity of the skin. Illustratively, the skin temperature sensor 115 may include a probe that contacts the skin and is used to detect the resistance value of human skin.

Skin wetness is typically caused by hot perspiration. Due to individual differences of users, although the temperature can be controlled by the temperature sensor, some users may feel some heat for the same temperature to cause perspiration. Since the resistance value of human skin is significantly reduced as the skin humidity increases, the stimulus of the electric pulse felt by the human body is stronger when the skin humidity increases. At this time, by providing the skin humidity sensor, when it is detected that the skin humidity is greater than a predetermined value, the result may be fed back to the control circuit, so that the control circuit may stop the heating process of the heating sheet in advance. Accordingly, the control circuit may be configured to control the intensity of the electrical pulse applied to the electrode pad 101 based on the detected skin humidity. When an increase in skin humidity due to, for example, perspiration is detected, the control circuit may reduce the intensity of the electrical pulses so that the intensity of the electrical stimulation perceived by the skin is substantially constant, avoiding discomfort due to the increased sensation of stimulation by the electrical pulses resulting from the increase in skin humidity.

Several other embodiments of the present utility model will be described in further detail below in conjunction with fig. 3 and 4.

According to an exemplary embodiment, the massager 100 may further include a fan 108 disposed within the housing and the housing is provided with an air inlet 1111 and

air outlets

1051, 1112 disposed at sides of the housing (as shown in fig. 3). The air inlet can be arranged at any proper position on the shell. Preferably, in consideration of specific use of the massager 100, for example, pressing the bottom of the housing by hand to adhere to the skin, the air inlet may be opened at other sides of the housing than the side where the air outlet is located.

In a specific embodiment, the fan 108 may be a turbofan. Although in the illustrated embodiment the air outlets are combined by

air outlets

1051 and 1112 formed in the upper housing part 105 and the lower housing part 111, respectively, it will be appreciated by those skilled in the art that the air outlets may also be formed in only one of the housing parts. One or more air inlets 1111 may be provided in the housing as desired, as described in more detail below.

Since the massage device has a function of heating the skin, other parts around the heated part may be heated up to cause sweating. For example, when the massager of the present utility model is used to heat and massage the human back neck, the user's head may be sweated in conjunction with the air outlet, and the air flow discharged from the massager may be blown toward the user's head to cool the user's head and facilitate sweat removal.

In addition, the user can place the massager 100 on a desk as a wrist massager and work with a mouse at the same time. Since long-term use of the mouse generally results in perspiration of the palm, the massager 100 is operated to operate the fan 108 and orient the air outlet of the massager 100 toward the mouse or the palm of the hand, thereby blowing air toward the palm of the user, promoting evaporation of perspiration and keeping the palm of the hand dry.

In an exemplary preferred embodiment, the housing of the massager 100 may be provided with a fan chamber 109 accommodating a fan 108 therein, the fan chamber 109 being provided with an air flow inlet 1091 and an air flow outlet which communicate with or are identical to an air outlet of the housing, and air flowing between the air inlet 1111 of the housing and the air flow inlet 1091 of the fan chamber at least partially flows through the circuit board 107. The fan chamber 109 may be an annular wall portion surrounding the fan 108 and may be integrally formed with the upper housing member 105 or the lower housing member 111 by molding.

Since the massage machine of the present utility model has a heating function, the heating sheet releases heat to the inside of the massage machine while continuously or intermittently releasing heat to the electrode sheet 101 during use, and thus the temperature of the inside of the massage machine is increased accordingly. And the increased temperature can adversely affect the circuitry within the massager. Therefore, the air flow in the massager is caused to flow through the circuit board 107, so that the circuit board 107 can be cooled by air, and the temperature of the circuit board is prevented from being too high.

The partially exploded perspective view of fig. 3 and the longitudinal cross-sectional schematic view of fig. 4 schematically show the flow path of the air flow inside the massager 100. It should be noted that, in order to clearly show the respective components inside the massager, the cross-sectional line of the cross-sectional view of fig. 4 is not along the longitudinal center line of the massager.

The air flow path inside the massager may be designed in any suitable manner to achieve the purpose of airflow through the circuit board 107. For example, as shown in fig. 3 and 4, in one particular embodiment, the circuit board 107 may be positioned with a gap between the bottom surface of the housing such that air entering from the air intake of the housing at least partially flows through the gap. In fig. 4, arrows with arrows schematically illustrate the path of the air flow into the housing of the massager 100 and within the massager.

In order to improve portability of the massager and to be usable at any time regardless of the use environment and conditions, on the one hand, a strap fixing portion 1052 may be provided at a proper position on the housing of the massager 100. As shown in fig. 1, strap fixing portions 1052 are provided at both ends of the upper housing part 105, respectively, and both ends of a strap (not shown) may be fastened around the two strap fixing portions 1052, so that a user may bind the massager 100 in place on the body through the strap, thereby allowing the massager 100 to be used during an exercise. For example, the massager may be secured to the back neck, back, leg, arm, wrist, etc. by straps.

On the other hand, as shown in fig. 2, the massager 100 may further include a battery 114 disposed within the housing. The battery 114 may be a rechargeable battery or a replaceable disposable battery (which may be selected based on the specific configuration of the massager).

Similarly, too high a temperature can also adversely affect the performance and life of the battery. Thus, in a preferred embodiment, as shown in FIGS. 3 and 4, air flowing between the at least one air inlet 111 of the housing and the air inlet 1091 of the fan chamber 109 at least partially flows through the battery 114. For example, the battery 114 may be disposed upstream or downstream of the circuit board 107 along the airflow, or may be fixed to the circuit board 107.

In another exemplary embodiment, the massager 100 may further include a speaker 113 disposed within the housing. The speaker 113 may be connected to and controlled by the control circuit in a variety of suitable ways, as will be readily understood and appreciated by those skilled in the art, and will not be described in detail herein. By providing the speaker 113, the massager 100 can be provided with a function of voice broadcasting or music playing, etc. of controlling operations. In a preferred embodiment, the speaker 113 may be disposed near the air intake 1111 of the housing. Through setting up the speaker at the air intake annex, be favorable to sending out the sound that the speaker sent smoothly in the massager to the air current that gets into through the air intake can play the cooling effect to the speaker equally.

Further, the massager 100 may further include an operating portion exposed to the outside of the housing and connected to a control circuit inside the housing, and the operating portion may include control buttons 106 and the like, for example. The massager 100 may further include a sliding pad or the like made of a material having a low friction coefficient provided on the outer bottom surface of the housing.

While the above description has illustratively described a number of preferred embodiments of the present utility model, it should be understood that various modifications or alterations to the embodiments disclosed in this specification, or obvious combinations or substitutions for such features, will occur to one skilled in the art based upon the teachings of this utility model. Therefore, the scope of the utility model should not be limited to the specific embodiments disclosed in this specification. The protection scope of the present utility model should be determined by the technical scheme defined in the claims and the equivalent technical scheme thereof.
