Description

Anti-bacterial toy with afunction of the melody and light}

The present invention relates to an antibacterial toy having a melody light emitting function. The melody, light emitting function and antimicrobial function given to the toy give an acoustic effect and a visual effect, and protect the human body by preventing bacteria that adversely affect the human body. Is used.

The present invention to realize this;

The inside of one toy consists of a melody emitting function that operates by the force of a magnet, and a toy 1 having an electronic circuit 5 embedded therein, and the other toy has only a magnet built therein so that the two toys 2 are close to each other. The battery power source 7 is supplied to the REED S / W 6 of the electronic circuit 5, and the melody IC is generated through the speaker 9 by the operation of the melody IC 8 and at the same time, the light emitting diode 10 is visually displayed. It is a toy that blinks or emits full body light.

Conventional touch-type switches have to be manually operated so that the melody sounds, which implies many problems, such as lack of durability due to increased use of the switch and the need for manual switch operation when the melody sounds.

In addition, the toy case (3) is to produce a toy using the antimicrobial composition specified in the Republic of Korea Patent Application No. 10-1999-0039425, it is to provide an antimicrobial toy product with improved safety and reliability of the product.

In general, a synthetic resin product exposed to a humid atmosphere may be a habitat for various germs. Due to the deterioration of toy resins due to the growth of germs, not only scratches and deterioration of the performance of the product, but also on the surface of the synthetic resin product There was a problem that causes the disease or have a fatal effect on health through the infection of the human body by. In particular, in the case of children's toys made of synthetic resin is used in direct contact with the child's skin, such children's toys products are harmful to the human body due to the bacteria inhabit the surface of the product as described above This occurred.

The present invention is devised to solve the above problems,

By operating REED S / W (6) by magnetic force, it is possible to solve the lack of durability due to the increase in use in toys that produce the melody effect by the operation of manual power switch, and REED S / W through the proximity of mutual toys ( 7) The automatic operation of the melody and the sound of the melody through the proximity of the play toy are characterized by increasing the interdependence of the play culture.

In addition, the antimicrobial effect on the toy can be permanently maintained, so that the user from various bacteria can improve the safety and reliability of the product.

1 is a perspective view according to the present invention.

2 is a melody and light emitting function electronic circuit according to the present invention.

12: Fixed switch connection terminal.

Embodiments and working examples of the present invention for achieving the above object are as follows.

First, the toy including the melody light emitting function of the present invention;

Melody and light-emitting toys (1) and a toy (2) containing only a magnet is composed of a set, one toy (1) has a REED S / W (in the electronic circuit (5) having a melody IC (8)) The flow switch connecting terminal 11 of 6) is automatically connected to the fixed switch connecting terminal 12 by the magnetic force of the mating magnet toy 2. That is, the REED S / W 6 operates in close proximity to the magnet toy 2 to supply the BATTERY power source 7 to the melody IC 8 to generate a melody sound through the speaker 9 and at the same time emit a light emitting diode ( 10) local flashing or whole body light emission.

Toys manufactured as described above were able to supplement the durability of the product according to the automation of the power supply switch compared to toys made by manual operation, and also has the convenience of being able to operate the toy only by the proximity of the magnet toy (4).

And toys with antibacterial function;

Antimicrobial PVC is manufactured and molded by adding certain weight% of inorganic antibacterial materials Cu-, Zn-, Ag-Zeolite, Ag-Ca phosphate, Ag-Zr-phosphate-based ceramics to thermoplastic resin such as PVC, and toy case (3) To prepare.

In this way, the antimicrobial effect of the product may be improved due to the mixed inorganic antibacterial material directly added to the thermoplastic resin, and the added inorganic antibacterial material plays a role of preventing the suppression of bacteria present in the synthetic resin. .

As a result, it is possible to manufacture environmentally friendly antibacterial toys, which gives an advantage in improving the safety and reliability of the product.

At this time, as a result of performing an antimicrobial experiment on the manufactured antimicrobial toys, the antibacterial rate against E. coli was more than 90%. In addition, the same rate of antibacterial activity was found in Staphylococcus aureus, mold, resistant Staphylococcus aureus and Bacillus subtilis.

Therefore, it can be seen that the antimicrobial effect against various bacteria and the case color change prevention effect by the bacteria inhabiting the toy case 3 are also combined.

And in order to measure the antimicrobial activity, the bacterial solution was shaken at 25 ° C. for 24 hours, followed by comparison of the bacterial counts (shaking speed 150rpm / min).

Psalm Classification Initial bacterial count After 24 hours contact Antibacterial rate [%] #One 5.3 × 10³ 2.8 × 10² #2 5.3 × 10³ 7.1 × 10² 99.97 # 3 5.3 × 10³ 1.2 × 10 99.99 #4 5.3 × 10³ 8.5 × 10ⁿ (n = 6) 99.99

In the above experiment, the surface area of the specimen was 100 cm 2, the test method was a Flask Flask Test Methode, and the test strain was E. coli (Escherichia coli) ATCC 25922 and was treated with an antibacterial toy specimen (# 1). Antimicrobial activity against toy specimens (# 2) mixed with 0.5 wt% antimicrobial material, toy specimens (# 3) mixed with 1 wt% antimicrobial material, and toy specimens (# 4) mixed with 3 wt% antimicrobial material I tested it.

The present invention exhibiting such antimicrobial properties, since the antimicrobial material is also present through the production by the inorganic antibacterial material mixing process, the antimicrobial effect can be exhibited semi-permanently and is suitable for application to infants and children's protective products.

Toys having various functionalities in accordance with the multiplication of toys are required. In particular, toys that operate the power switch manually among toys given melody or light emitting function have a problem that the product cannot be used continuously for a long time due to lack of durability of the switch part. By supplying power to the melody and the light-emitting electronic circuit, it was possible to improve durability with an automatic switch configuration.

And recently, due to the serious air pollution and water pollution, it is a fact that the bacteria have an adverse effect on the human body can not be known. Therefore, antimicrobial products are required to minimize the damage to the human body from such bacteria.

The present invention as described above, by containing an inorganic antibacterial material in the synthetic resin that is the main material in the manufacture of the toy product has an advantage that can improve the antibacterial effect and at the same time improve the durability.
