Abstract

The utility model relates to a laser head cleaning device for a CD player and a video disc player, particularly a laser head cleaning disk with a testing function. The shape of the laser head cleaning disk is the same as the shape of the normal laser disk (CD); the utility model comprises a disk and a cleaning brush; the utility model is characterized in that the starting position of the optical signal recording area of the laser disk is provided with a set of cleaning brushes; the cleaning brushes are radially symmetrical arrangement. One set of cleaning brushes has 2-3 cleaning brushes, wherein, the cleaning brushes comprises a cleaning brush (1), an electrostatic clearing brush (3), a cleaning liquid absorbing brush (4), etc. The cleaning brush can be fixed on the laser disk by the bonding mode or the insertion mode. The laser disk is also recorded with the test aural information, so that the utility model can test the cleaning effect and can test the performance of the laser playing equipment. The utility model has the advantages that the utility model has good cleaning effect on various dirt and the utility model is one object with multi-function, etc.

Description

The laser head cleaning device

The utility model relates to a kind of compact disc player, video disc player laser head cleaning device, particularly a kind of laser head cleaning disc with test function.

At present, the cleaning of laser head maintenance in the CD drive of compact disc player, video disc player and computing machine, what generally adopt is that manual operations or special-purpose cleaning disc are finished, and manual operations is the scuffing laser head easily, and the layman should not adopt.Existing cleaning disc is the single clearing brush to be set on the laser disc constitute, and this device is because structural design is unreasonable, and cleaning effect is undesirable.

The purpose of this utility model provides a kind of automatic flushing device of compact disc player laser head, and it has the dual clean brush, and cleansing power is strong, and is effective, and has multiple test function.

The purpose of this utility model is achieved in that it has profile disc and the cleaning brush the same with the laser disk (CD) of standard, it is characterized in that laser disk optical signalling recording areas reference position is provided with one group of cleaning brush, and cleaning brush is with the disc radial symmetric arrangement.

Described one group of cleaning brush can be 2～6, is preferably 2～3 cleaning brushs.

The hairbrush that described one group of cleaning brush can be a same type constitutes, and also can be that dissimilar cleaning brushs is provided with at interval.

Because what the utility model adopted is one group of cleaning brush, it is fairly obvious at cleaning effect, particularly selects dissimilar cleaning brush combinations for use, all good cleaning effect will be arranged to various dusts and dirt.In addition, because the rotation of cleaning brush symmetric arrangement cleaning disc is steady.Add and recorded multiple test sound equipment on the cleaning disc, make this cleaning disc have multiple function.

Below in conjunction with accompanying drawing the utility model is explained in more detail.

Figure is the front elevation of a kind of embodiment of the present utility model.

Fig. 2 is the side view of a kind of embodiment of the present utility model.

Fig. 3 is the front elevation of another kind of embodiment of the present utility model.

Fig. 4 is the synoptic diagram of a kind of cleaning brush in the utility model.

Fig. 5 is the synoptic diagram of the another kind of cleaning brush in the utility model.

As shown in Figure 1, standard laser dish (CD) is provided with one group of cleaning brush, and this group cleaning brush comprises cleaning brush 2 and 3, and their radial symmetry are arranged in CD dish signaling zone near on the initial position.Two cleaning brushs 2 and 3.Cleaning brush 2,3 is identical micro-brush, and also dissimilar cleaning brushs is common cleaning brush as cleaning brush 2, can be made by the silk of various softnesses, and cleaning brush 3 is removed brush for the static with the function of destaticing, and bristle is made by the Electrostatic Absorption material.

Fig. 2 is the side view of Fig. 1, and cleaning brush 2,3 is basically perpendicular to the setting of CD disc.Cleaning brush can be fixed on the CD disc by bonding way, also can the implantation mode be fixed on the CD dish.Cleaning brush 2 is depicted as bonding way among Fig. 2, and cleaning brush 3 is the implantation mode.

Shown in Figure 3 is the cleaning CD dish with one group of three cleaning brush, and the hairbrush 4 of common micro-brush 2, Electrostatic Absorption brush 3, absorption cleaning fluid is symmetricly set on the CD disc alternate each other 120 ° respectively.These three kinds of cleaning brushs that brush can be an identical type also can be any two combinations, and this should decide on concrete cleaning requirement.

As shown in Figure 4, clean with water by bristle 5 and brush 6 and constitute.Bristle 5 can be selected different materials for use according to different cleaning needs, has multiple material available in the current material.The hardness of bristle should be moderate, really up to the markly will impair laser head, and it is not good to cross soft cleaning performance.

Shown in Figure 5 is columniform cleaning brush.This brush more carefully can be arranged side by side and constitute a cleaning brush, shown in brush 3 among Fig. 2.

The peripheral optics signal recording area of cleaning brush on the laser cleaning dish of the present utility model, depositing to record has the test aural information, and include left and right sound channels and test, the test of height range, sound is tested mutually and the actual play of music is checked.These tests promptly can be checked the cleaning effect of laser head, and this cleaning disc can be used as laser and broadcasts machine performance test dish simultaneously.Therefore the utlity model has multiple utility function.
