It should be noted that the same configuration may be indicated by the same reference numeral in each drawing. Additionally, detailed descriptions of the functions and configurations of known technologies that are judged to unnecessarily obscure the gist of the present invention may be omitted.

First, a thermal massage ball structure with improved heat conduction efficiency according to an embodiment of the present invention will be examined through FIGS. 1 to 7 as follows.

The heated massage ball in this embodiment includes a cylindrical frame 20 made of metal for heat conduction inserted into the massage ball body 10, and a heating element made of metal such as aluminum is installed inside the cylindrical frame 20. A block 30 is provided, and inside the heating block 30, a plurality of electrode plates 50 and a plurality of insulators 70 are formed in a symmetrical form on both sides around the PTC element 40, which is a heating element. structure is formed.

At this time, the cylindrical frame 20 in the present invention has a structure in which two pairs forming a semicircular cross-sectional structure are mutually detachable, and the opposing surfaces have a block seating groove 21 on which the heating block 30 is seated. ) and a removable protrusion 22 are each configured.

A hollow portion 23 is formed inside the cylindrical frame 20, and the removable protrusions 22 are provided with protruding locking protrusions 22a for mutual locking action.

In addition, a PTC guide 60 made of metal with a square-shaped guide groove 61 formed through it is inserted into the heating block 30 to support the PTC element 40. It can be seen that the electrode plate 50 and the insulator 70 are inserted into the heating block 30 in a symmetrical shape on both sides of the center.

Meanwhile, a fastening protrusion 55 is provided bent in a right-angled shape at the upper end of the electrode plate 50, and a fastening groove 65 into which the fastening protrusion 55 can be inserted and supported is provided at the upper end of the corresponding PTC guide 60. It can be confirmed through FIG. 2 that this is formed to support the position of the electrode plate 50.

Let's look at the effects of assembling and using the thermal massage ball of the present invention, which has such a configuration.

First, in the massage ball assembly process, the PTC element 40 is inserted into the guide groove 61 of the PTC guide 60, and the electrode plate 50 and the insulator 70 are stacked in a symmetrical form on both sides. It is inserted into the heating block (30).

That is, at this time, the position of the fastening protrusion 55 provided on the upper part of the electrode plate 50 is supported by fastening to the fastening groove 65 of the PTC guide 60, thereby ensuring stable guidance of the PTC element 40. The middle PTC structure can be inserted into the heating block 30.

In this way, the heating block 30 into which the PTC structure is inserted is assembled and fastened to the cylindrical frame 20 while being seated in the block seating groove 21 of the cylindrical frame 20. In this case, two cylindrical frames ( 20) can be maintained in a coupled state by the locking protrusion 22a formed on the mutually attachable protrusion 22, thereby enabling more rapid assembly work.

Thereafter, the production of the heated massage ball is completed by assembling and fastening the cylindrical frame 20 to the massage ball body 10.

The heated massage ball of the present invention manufactured in this way generates heat in the PTC element 40 due to the power applied to the electrode plate 50, and heat conduction occurs through the heating block 30 and the cylindrical frame 20, providing massage. Rapid heat transfer to the ball body 10 is achieved, resulting in an efficient heating effect.

In particular, the size of the PTC element 40 can be reduced by forming an assembly structure that maximizes the thermoelectric function while minimizing heat loss inside the massage ball.

In addition, since the massage ball of the present invention has a prefabricated structure, when a failure occurs in the internal components including the PTC element 40, the cylindrical frame 20 can be quickly separated and the internal components can be easily repaired and replaced. indicates.

Therefore, in the thermal massage ball of the present invention, heat generated from the internal PTC element is transmitted more quickly and uniform heat conduction efficiency can be achieved throughout, thereby improving the thermal massage effect.

In particular, it is possible to miniaturize the PTC device, thereby reducing the production cost of the product, and has the advantage of improving production efficiency through the attachment and detachment structure of the cylindrical frame.

Meanwhile, Figure 9 shows a configuration according to another embodiment of the present invention, in which the hollow portion 23 of the cylindrical frame 20 is filled with a thermoelectric filler 24 to improve heat conduction efficiency, and the thermoelectric filler ( 24) is 40 to 70% by weight of epoxy vitrimer resin with excellent heat conduction efficiency, 10 to 20% by weight of aluminum powder, 5 to 20% by weight of graphene, 10 to 30% by weight of dimethoxy dimethyl silane, and 1 to 1% of butyl paraben. The mixed composition is formed at a ratio of 10% by weight. This thermoelectric filler can also be charged inside the heating block 30.

When such a configuration is achieved, the heat source generated from the PTC element 40 due to the thermoelectric filler 24 filled in the hollow part 23 of the cylindrical frame 20 is transmitted to the massage ball body 10. Heat transfer efficiency can be further improved while minimizing heat loss.

In particular, since graphene and butyl paraben components are mixed in the thermoelectric filler (24), it prevents the thermal curing of the epoxy vitrimer resin and the generation of voids, and dimethoxy dimethyl silane is used in the thermoelectric filler (24). ) performs the function of strengthening the charge density.

In addition, Figure 10 shows another embodiment of the present invention, in which an adhesion coating layer 25 is formed in the block seating groove 21 to improve adhesion to the heating block 30.

It is desirable to form a mixed composition.

When such a configuration is achieved, thermoelectric efficiency can be improved due to improved adhesion to the heating block 30 due to the formation of the adhesion coating layer 25.

In particular, since potassium chromate and cobalt naphthenate components are mixed in the adhesion coating layer 25, oxidation and discoloration of the coating layer are prevented, sepiolite improves coating flatness, and phenylalanine tetrahydroxylase is polysulfone. It functions as a catalyst for the resin to maintain elasticity, and polybenzimidazene, a polycondensate, strengthens the durability of the adhesion coating layer 25 to prevent it from falling off, and lithium hydroxide improves the bonding strength between the mixture materials to create voids. It performs the function of suppressing. In addition, the additionally added isoflavonoid improves the surface lubricity of the adhesive coating layer 25 to prevent contamination due to adhesion of foreign substances, and polycaprolactone and sodium fluoride each have the function of suppressing the generation of bubbles during the coating layer formation process. It will be performed.
