Description

Toothbrush displaying use time}

The present invention relates to a toothbrush, and more particularly, to a use-time display toothbrush that can easily and conveniently grasp the appropriate toothbrush replacement time by displaying the time when the toothbrush should be started or the time to end the use, etc., in a simple structure will be.

A toothbrush is a hygiene product used to remove foreign substances including food residues by wiping the inside of the oral cavity, such as teeth and gums. A conventional toothbrush is composed of a rod-shaped gripping part held by hand and a head part put into the oral cavity, and it is common to apply toothpaste to the bristles provided in the head part to wipe the inside of the oral cavity.

Proper brushing is essential for oral hygiene and health. In particular, the bristles that come in direct contact with the internal tissues of the oral cavity must have an appropriate shape and strength to clean teeth and gums without damage. However, as the use time of the toothbrush elapses, the bristles of the bristles are worn at the ends and deformed, resulting in poor brushing effect and damage to teeth or gums. Accordingly, when the appropriate period of use has elapsed, the toothbrush should be replaced with a new one, and 2 to 3 months is recommended as the preferred toothbrush replacement time.

In order to recognize the replacement time of the toothbrush, it is cumbersome and inefficient for the user to memorize or separately memorize the time when the use of the toothbrush is started or the time to end the use of the toothbrush. Especially for children and the elderly, it is more difficult to rely on memories or records. The start or end time of use is written on one side of the toothbrush with a pen or attached in the form of a sticker, but due to the nature of the toothbrush in contact with toothpaste, water, and the user's hand, the written content is erased or the attached sticker falls off, making it less effective.

Accordingly, most people decide when to replace the toothbrush by visually examining the abrasion and deformation of the bristles. On the contrary, there is also a problem of waste due to frequent replacement of toothbrushes than necessary.

In order to solve this problem, the 'toothbrush equipped with an exchange date display part' of Korean Patent Application Laid-Open No. 10-2009-1022877 (hereinafter referred to as Prior Art 1) and the 'toothbrush' of Korean Utility Model Publication No. 20-2013-0002439 ( Hereinafter, prior art 2) and the like have been disclosed. Prior Art 1 and Prior Art 2 are provided with a mechanically operated date display means so that the use start date of the toothbrush can be displayed on the toothbrush itself, through which it is possible to easily determine the appropriate replacement time of the toothbrush.

However, in the prior art 1 and 2, there is a problem in that the structure of the date display means is complicated in common, so the manufacturing cost is high, and the convenience of use of the toothbrush is deteriorated due to an increase in weight and volume.

1. Republic of Korea Patent Publication No. 10-2009-1022877, toothbrush provided with an exchange date display, 2009.12.01 publication 2. Republic of Korea Public Utility Model No. 20-2013-0002439, Toothbrush, published on April 24, 2013
