Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bell-shaped attachment for a heat-broiling type pine serge device, which is a heating body of a broiling-type pine surge device, which has a constant-temperature and particularly vibration-resistant structure, and which allows safe treatment.

Traditionally, pine massage is a collective term for massaging, shiatsu, acupuncture, and other techniques, and has been widely practiced in the private sector since ancient times.

In addition, in order to treat these, as a therapist,
It has been practiced by masseurs and shiatsu therapists, but in order to become a massage therapist, a long period of training and experience are required.

However, in modern times these have gradually been mechanized,
There are various pine surge devices available on the market.

Each of these pine surge devices has its own characteristics, but they can be broadly classified into acupressure type and hot-broiling type.They also vary in size, but can be roughly divided into fixed type and portable type.

The inventor first proposed a hot-roasting pine serge device, which combines hot-roasting and vibration.

Generally, this type of heating element uses a heating wire and utilizes heat generated by electrical resistance.

A nichrome wire is normally used as the heating wire, and the heating elements of the present hot-broiling type massager are evenly distributed in the four bell-shaped hollow shells of the attachment.

Therefore, in order to maintain each attachment at 50℃ to 60℃, the electric heat capacity is small, and the total electric heat capacity is
5W/h is sufficient, which is 1.25W/h per attachment.

For this reason, use a heating wire with a diameter of 1 mm or less.

However, in the case of a vibrating pine surge device such as the one of the present invention, fine heating wires are easily cut due to vibration, and since the fine heating wires are easily oxidized and deteriorated, there is a risk that deteriorated parts may be easily cut.

Furthermore, it is difficult to maintain the attachment at a constant temperature, for example, if you use a heating wire with an empirical heating capacity to maintain the temperature at 55℃, it will take 20℃ to reach the same temperature, although it varies depending on the external temperature. ~30
It takes minutes. Conversely, if a heating wire with a large electric heating capacity is used to reach a constant temperature quickly, the temperature will reach the constant temperature quickly, but the temperature will gradually rise over time, reaching 60°C or more after one hour, for example.

In order to avoid this, attempts were made to incorporate a temperature regulator into the circuit, but the sensitivity of the temperature regulator was poor and no significant effect was observed.

The purpose of this invention is to solve the above-mentioned drawbacks, and for this purpose, a PTC body is used as the electric heating body, and it is configured to be vibration resistant, so that the temperature can be automatically controlled and stable treatment can be performed. Provides a bell-shaped attachment for a hot-broiling pine serge device.

Embodiments based on the present invention will be described below with reference to the drawings.

Fig. 1 is a schematic vertical cross-sectional view of one of the four identical bell-shaped attachments of the body of the hot-roasting pine sage device according to the present invention, and Fig. 2 is a cross-sectional view of the hollow shell of the bell-shaped attachment shown in Fig. 1 taken along line X-X'. 2 shows a cross-sectional view along the line.

In FIG. 1, reference numeral 1 denotes a main body of a searing pineapple according to the present invention, and 1A is an outer shell covering the upper part of the main body, which is provided with an insertion opening 1A' for an attachment according to the present invention described below. In addition, the bottom plate part 1B of the main body is provided with a cylindrical body part 2 which stands upright on the left side in the drawing and has a cylindrical hollow part 2A at the top into which the following attachments according to the present application are fitted, and the right side in the drawing is located in the center. It is directly connected to the diaphragm 13 of the vibrator 12 with a nut or the like. When the vibrator 12 vibrates by being energized, the entire body of the pine surger, including the attachment, vibrates.

The constituent material of the main body formed in this way is molded from polycarbonate resin. This is because polycarbonate resin is easy to mold, has high impact resistance, and also has high heat resistance. The appearance is lighter and softer than iron.

Next, the bell-shaped attachment 4 according to the present invention is fitted and inserted onto the spring 3 delivered into the cylindrical hollow part 2A of the cylindrical body 2 whose upper part is open.

In this case, as shown in FIG.
The insertion opening 1C of the attachment 4 on the top surface is fixed so as to engage with the upper end peripheral edge of the cylindrical hollow part 2A, and a narrow belt-shaped projecting ring with a notch is provided along the upper end peripheral edge of the cylindrical hollow part 2A. It forms 1Ca.

Therefore, the attachment 4 is prevented from escaping from the cylindrical hollow portion 2A by this band-shaped protruding ring 1Ca. Further, the spring 3 delivered into the cylindrical hollow portion 2A resists the compression and contraction of the treatment body on the protruding upper surface outside the outer shell of the attachment 4, and alleviates the compression and contraction changes, thereby increasing the treatment effect.

Next, the bell-shaped attachment 4 according to the present invention
I will explain in detail.

The bell-shaped attachment 4 is open at one end and consists of a hollow bell-shaped shell 4A, made of thin metal such as brass, iron, etc., and the outer surface is chrome plated to resist friction and at the same time to soften the appearance. ing.

In addition, at least three surface protrusions 4B are attached to the bottom of the outer surface of the bell-shaped shell 4A along the outer surface of the shell so as to engage with the notches of the band-shaped protruding ring 1Ca of the insertion opening 1C of the attachment 4 of the outer shell 1 of the main body. There are more than
When inserting the attachment 4, the surface projecting body 4B is engaged with the notch, and the rear attachment 4 body is inserted while being rotated. Since it is formed in this way, the main body of the attachment 4 does not escape from the cylindrical hollow part 2A, and is guided into the hollow part by these surface projections 4B and stably held.

Next, a resin or aggregate 5 is fitted into the hollow part of the bell-shaped shell 4A to fill it. In this case, it is sufficient that the resin used is melamine resin, silicone rubber, or the like, and has a heat resistance of 150° C. or higher. The aggregate is made by soaking silica sand or the like in silicone resin and heat-compressing it.

These resins or aggregates support the PTC body and the like described later, and at the same time heat the bell-shaped shell 4A of the attachment by using the heat generated by the PTC body as conductive heat, thereby providing a pleasant feeling of treatment.

In addition, a stepped recess 6 is bored in the center of the resin or aggregate 5, and a thick square PTC body 7 is fitted into the recess 6, and a lower part of both sides of the PTC body 7 is formed. Silver is welded to form an electrode 8, to which a tuning fork meter-shaped heating body consisting of two conductor pieces 9 closely contacted or welded is fitted.

Furthermore, in this case, by filling the crotch of the tuning fork meter-shaped conductor piece 9 with resin or aggregate 5A in the same manner as described above, the heating body can be fixed in a vibration-resistant manner, which is also a feature of the present invention. .

Further, the PTC body 7 is also called a so-called POSISTOR, and is made of BaTiO ₃ semiconductor ceramics, for example, and is a heat-sensitive resistor conductor having a positive temperature coefficient of resistance.

For example, the one used in this invention is a POSISTOR that maintains a temperature of around 55℃.

However, the power supply is 100V.

Next, 8 is a conductor piece 9 that comes into contact with the electrodes A and B of the PTC body, and is made of a phosphor bronze piece, the tip part of which is bent into a U shape, and the tip part is made of elastic material to make contact with the electrodes A and B of the PTC body.
The PTC body 7 is held in close contact with both sides of the PTC body 7 so as to have a tuning fork shape in cross section.

Note that other metal conductors may be used instead of phosphor bronze. In addition, phosphor bronze contains copper (Cu) containing beryllum, phosphorus, etc., and has a high elastic modulus and high heat resistance.Because it has a particularly high elastic modulus, it can be bent into a U-shape at the tip as in the present invention. can maintain close contact with the electrode.

After being configured in this way, the bell-shaped shell 4A and the resin or aggregate 5 filling the hollow part of the shell
5A and the bottom cover 10 are bonded and fixed with adhesive resin, for example, silicone resin. In addition, at that time, the conductor piece 9
The power supply conductor 11 welded to the end of the bottom cover 10 is pulled out from the through hole 10A of the bottom cover 10 and connected to the power supply.
These extraction holes are also fixed with resin.

The bell-shaped attachment according to the present invention is characterized by being integrally constructed and held in a vibration-resistant manner.

Next, as shown in FIG. 1, the bell-shaped attachment according to the present invention is fitted and inserted onto the spring 3 delivered into the cylindrical hollow part 2A of the cylindrical body of the pine surge device body 1 as described above. However, this cylindrical body 2 is directly connected to a bottom plate portion 1B of the main body, and this bottom plate portion 1B is directly connected to a diaphragm 13 of a vibrator 12 on the right side of the drawing with a nut or the like. With this structure, when the vibrator 12 vibrates by being energized, the entire body of the massager body, including the attachment, vibrates, and at the same time, the heating element in the attachment is also energized and heated, so that the device functions as a hot-broiling type massager. Incidentally, reference numeral 14 denotes rubber feet that act to eliminate vibration noise even when the main body is placed on a desk.

As described above, the hot-roasting pine serge device shown in the present application is configured to apply temperature and vibration at the same time.

Next, it will be explained in detail using examples.

When electricity is first applied to the broiling-type pine sage device equipped with the electric heating element according to the present invention, the vibrator inside the device is activated and the device vibrates slightly. At the same time, the electric PTC body 7 in the four attachments on the top of the vessel gradually generates heat. This heat is transferred to the resin body 5 enclosing the PTC body 7, heating it, and this heat is transmitted to the bell-shaped shell 4A of the attachment, which gradually becomes warmer. After about 5 minutes, the temperature will be 47.5°C to 49.5°C, and you can begin treatment immediately.

The measurement results of the change in outer shell surface temperature over time in this case are as shown in FIG.

As is clear from the figure, the temperature reached approximately 58.5℃ 15 minutes after electricity was turned on, and then the temperature gradually became constant at approximately 58.5℃.
℃, and this rising and falling wave becomes smaller and the temperature remains at 58℃ after approximately 20 minutes.

However, in this case, the room temperature was approximately 28°C.

Furthermore, in this case, the thermal sensation caused by the treatment is very mild. This is because the heat generated by the PTC body is transferred to the resin body, but in this case the heat is entirely transferred to the attachment shell 4 by conduction heat.

In this way, for example, the pine surge device was applied to the back for treatment, and the pine surge effect was sufficient if the treatment was performed for 15 to 20 minutes.

From the above, unlike conventional nichrome wire-based heating elements, the heating element of the present invention is far more vibration-resistant and stable as a heating element, and is housed and held in a resin body, so there is no risk of wire breakage due to vibration. There is no risk of wire breakage due to corrosion due to natural oxidation, as is the case with heating wires, and therefore, the durability is high, and the expected heating temperature can be maintained at a constant temperature. As a result, the therapeutic effect can be fully satisfied when used as a warm-broiling type pine surger.
