Description

Head Replaceable Toothbrush {A TOOTHBRUSH WITH A HEAD OF EXCHANGING TYPE}

The present invention relates to a head replaceable toothbrush, and more particularly, to replace only the corresponding part when the bristles are damaged, the head replaceable type so that a predetermined function is performed while the lamp is automatically turned on only in normal use of the toothbrush. It is about a toothbrush.

In general, the toothbrush which is most popularly used as a hygiene tool for maintaining the inside of the mouth and teeth is a head part which is formed at the end of the toothbrush which can be held by the user and the bristles that brush the teeth are brushed. It is composed.

If the toothbrush configured as described above is used for a certain period of time, the bristles are worn or damaged, and at this time, the toothbrush of the new product is replaced. However, the bristles are easily damaged during the use of the toothbrush, but the toothbrush is kept intact as long as it is not broken, the entire toothbrush is discarded, there is a problem that wastes resources, pollutes the environment, and increases the cost of consumers.

Accordingly, in recent years, by using a toothbrush configured to be detachably attached to the toothbrush stand head portion that is bristled with bristles was able to solve some of the conventional problems as described above. However, the general form of the toothbrush which the head portion is detachably configured as described above is configured so that the protrusions formed separately from the neck portion of the toothbrush rod and the head portion of the bristles are implanted so that the entire head portion including the protrusions is replaced when the bristles are replaced. Since there is a lot of waste to be replaced, there is a problem that causes waste of resources and environmental pollution.

On the other hand, the toothbrush as described above is a variety of bacteria remaining before and after use to harm the dental health, because various disinfection mechanisms for removing such bacteria are used, but must be purchased separately, the cost burden increases and disinfection installed in a separate space Since the sterilization operation should be performed by using a device, there was a problem in use.

Accordingly, in recent years, a toothbrush has been invented so that the sterilization device is configured on the toothbrush itself and is conveniently used. As a prior art of such a toothbrush, the Korean Utility Model Registration Application No. 20-2003-0001664 is presented to provide a coin-type battery. An ultraviolet lamp that emits light is configured as a power source so that the sterilization function is performed by the ultraviolet light emitted according to the operation of the switch. However, such a sterilizing toothbrush has a problem in that the sterilization process is to use the light emitted from the ultraviolet lamp directly because the glare is generated by the ultraviolet radiation from a long distance.

And the toothbrush provided with the conventional lamp as described above is configured to turn on the lamp through the operation of the switch button, so that the operation of the switch button is necessary before and after use, there is a somewhat inconvenient problem in use, When the lamp is turned on even before and after the time when the direct brushing is not performed, and the switch button is not turned off after the use, the lighting state of the lamp is continuously maintained, which causes a lot of energy consumption.

In particular, the toothbrush provided with such a conventional lamp is brushed by operating the switch button to turn on the lamp, so that glare is generated by ultraviolet light or infrared light emitted from the lamp, which severely weakens or damages eyesight. There was a problem.

The present invention is to solve the above conventional problems, head replacement type to reduce the waste of resources and environmental pollution and to reduce the cost of consumers by making it easy to replace only the corresponding part when the brush head is damaged The purpose is to provide a toothbrush.

Another object of the present invention is that when the bristles are damaged, only the corresponding parts can be easily replaced, and at the same time, the lamp is automatically turned on only during normal use of the toothbrush so that a predetermined function can be performed, thereby improving safety and convenience in use and increasing the consumer's cost. It is an object of the present invention to provide a head replaceable toothbrush that can be saved.
