Description

Mouse with anti-pollution function

(1) technical field

The utility model relates to a kind of computer mouse, especially relates to a kind of mouse that adopts trace ball to operate the roller of control vernier.

(2) background technology

Existing computer has desktop computer and portable computer, and what cooperate with it is wire mouse and wireless mouse.Mouse following all is provided with the trace ball of an operation control vernier, no matter is fit strip slides, or the trace ball of directly stirring, and its trace ball and backing plate surface are non-conductor.And three rollers that driven by trace ball are also mostly constituted by nonconducting plastic material, and metal is constituted, and bearing is also constituted by nonconducting plastic material.Generally speaking, the surface of trace ball, roller and backing plate in the mouse does not all have the design of electric conductor ground connection, thereby the static that roller friction is produced can't eliminate, and causes attracting the batting dust to be stained with and sticks on roller, thereby influence operational sensitivity.As for utilizing finger directly to stir trace ball, because spheroid is a non-conductor, so only can eliminate and point the static of contact site, the elimination of pair roller static and not exclusively also is the anti-fouling effect of pair roller is very desirable.

(3) summary of the invention

A catalogue of the present utility model be to overcome above-mentioned the deficiencies in the prior art and the mouse with anti-pollution function is provided.Because static is the main cause that causes roller to adhere to dirt, mouse of the present utility model provides simplifies the conduction approach of ground connection, or utilizes the mode of human body release electrostatic, thereby can eliminate the static on the roller, makes mouse free of tenent hair and dust dust.

The purpose of this utility model can realize by following three technical schemes.

One of scheme: a kind of mouse with anti-pollution function, it is characterized in that using wherein each roller instead conductive material makes, and conducting strip is set at the outside surface of casket body, the position that contacts with operator's hand, make roller be connected conduction with conducting strip again.

Two of scheme: a kind of mouse with anti-pollution function is characterized in that using wherein each roller instead conductive material makes, and makes it ground connection.

Three of scheme: a kind of mouse with anti-pollution function, it is characterized in that trace ball wherein, adopt conductive material to make on its surface at least.

Mouse of the present utility model is compared with the mouse of prior art, has the following advantages: it provides simplifies the conduction approach of ground connection, or utilizes the mode of human body release electrostatic, thereby can eliminate the static on the roller, makes mouse free of tenent hair and dust dust.

Below in conjunction with drawings and Examples, further specify the utility model.

(5) embodiment

Fig. 1 to Fig. 5 illustrates the structure of a kind of embodiment of the present utility model.With reference to Fig. 1, Fig. 2 and Fig. 3, this is a kind of wireless mouse, and it comprises: last casket body 11 and following casket body 12 by plastic colloid cover the casket body 1 that forms; Part is exposed to down casket body 12 bottom surfaces, is used for trace ball 5 with the backing plate friction rolling; Roller 2a, the 2b, the 2c that driven by trace ball 5, the cylindrical roller 2a and the 2b that wherein are used for counter, the one side respectively is fixed with shading wheel disc 22a, the 22b of concentric, shading wheel disc 22a and 22b match with the photoelectric subassembly 71a, the 71b that are made up of light-emitting component and photoelectric crystal, in order to send the counting electric signal; Opposite side is fixed in axle center 21a, the 21b among bearing 121a, 121b, 122a, the 122b, and then each is exerted pressure by reverse spring 8a, the 8b that are placed in right cylinder 124, makes roller 2a and 2b push trace ball 5 to; Another roller 2c plays the thrust effect, rotates freely in preset range with restriction trace ball 5; Circuit board 7 and signal launch window 72.The above is the inner structure of prior art mouse.

And the given a kind of embodiment of mouse of the present utility model utilizes human body to discharge the static of roller (2a, 2b, 2c), adheres to dirt to prevent roller (2a, 2b, 2c).Concrete scheme: be provided with conducting strip 3a and 3b in casket body about 1 two outsides, as shown in Figure 3, be fixed in casket body 12 down, and be provided with packing ring 33a, the 33b that is held on nut 32 and has terminal with bolt 31 and nut 32; Settling metal to reverse right cylinder 124 diametric planes of spring 8a and 8b, fix a metal sleeve 4, as shown in Figure 4 with terminal; In addition, roller 2c can rotate freely on the 21c of axle center, and axle center 21c then is clamped condition and is fixed among bearing 123a, the 123b, as shown in Figure 5.Above-mentioned roller 2a, 2b, 2c and axle center 21a, 21b, 21c make of metal material, make it to have electric conductivity.Present embodiment, as shown in Figure 3, for roller 2a, 2b, 2c are communicated with conducting strip 3a, 3b conduction, this conducting strip 3a, 3b link to each other with lead 6a and 6b through packing ring 33a, the 33b with terminal, and each is contacted with axle center 21a, the 21b of roller 2a, 2b respectively through reversing spring 8a and 8b again and lead 6b is through the metal sleeve 4 with terminal; In addition, roller 2c then links to each other through its axle center 21c and lead 6c and with packing ring 33b and forms.In sum, because the conducting strip 3a of this casket body 1 left and right sides and 3b are sitting at the part that operation mouse person's finger must contact, again because conducting strip 3a and 3b conduct electricity with roller 2a, 2b, 2c communicates.So, do not have the plastic colloid trace ball 5 of electric conductivity and the static that roller 2a, 2b, 2c friction are produced, can be released into human body via conducting strip (3a and 3b), charged to prevent roller (2a, 2b, 2c), thereby prevent dirts such as roller (2a, 2b, 2c) absorption batting dust, and reach antifouling purpose.

Above-mentioned is the embodiment of wireless mouse.An if wire mouse, clearly, can omit the setting of conducting strip 3a and 3b, and lead 6c and the metal sleeve 4 of having terminal are connected, again via the cable between another lead remittance mouse and host computer, carry out ground connection again, also can release the static of roller (2a, 2b, 2c), and reach antifouling purpose.

Release the structure of static for simplifying roller (2a, 2b, 2c), and reach antifouling purpose equally, it also is another technical scheme of the present utility model, described trace ball 5, at least at its superficial layer, make of conductive material, for example: with the spheroid of the rubber and plastic glue material institute moulding that contains the bronze end, or hollow metal ball body, or plastic cement spheroid appearance imposes and electroplates or vacuum is being plated metal film etc. and all can.For showing the advantage of this programme, be described as follows by Fig. 3 below:

When this trace ball 5 is an electric conductor, and when being used in wireless mouse, can omit lead 6b and reach the metal sleeve 4 of having terminal, and roller 2a, 2b and axle center 21a, 21b, can be by plastic rubber shaping than the metal cheapness, roller 2a, 2b can connect conducting strip 3a and 3b through lead 6c through roller 2c and the axle center 21c thereof of trace ball 5 by the metal quality again because of fricative static.When being used in wire mouse, then can importing cable and lead to host computer ground connection via lead 6c.Moreover, this programme is used to utilize finger directly to stir the wire mouse of trace ball 5, wireless mouse (consulting Fig. 6) or portable computer person, not only can exempt lead 6a, 6b, 6c and conducting strip 3a, 3b, and roller 2a, 2b, 2c, can be with nonconducting plastic material moulding, the static that roller 2a, 2b, 2c are produced because of friction can be discharged through operator's finger by trace ball 5, and is quite helpful to reducing cost like this.

Mouse of the present utility model, to removing the static on the roller, to eliminate the dirt on the roller, effect is very obvious, and never uses in existing mouse or portable computer, so propose patented claim.
