Abstract:
1. A wireless mouse for a computing device operating along with a wireless receiver detachably installed on said computing device by transmitting RF signals to said wireless receiver, said wireless mouse comprising a front button cover, a rear cover, a main body, a circuit board, a snap-on element, and a bottom seat, wherein said rear cover has a rectangular opening at a rear end to expose an insertion slot of a receptacle chamber configured in a rear section of said main body, a door is configured at said insertion slot by a hinge wound with a biasing spring at a bottom of said insertion slot such that when said wireless receiver is inserted into said receptacle chamber via said insertion slot, said door will be pushed open, and when said wireless receiver is removed, said door will return to original position to close said insertion slot by said biasing spring, said receptacle chamber has a dimension matching dimension of said wireless receiver so as to accommodate said wireless receiver completely inside, said main body is positioned on a top of said circuit board and allows a control wheel of said circuit board exposed to outside of said main body, said circuit board is supported by and fixedly installed on said bottom seat, said snap-on element is configured on said bottom seat at a location corresponding to a bottom of said receptacle chamber for positioning and locking of said wireless receiver inside said receptacle chamber, and when said wireless receiver is inserted into said receptacle chamber, a front end of said wireless receiver will press against a spring element and said spring element will remain in a compressed state as said wireless receiver is held in position in said receptacle chamber by said snap-on element, said spring element has a first end fixedly attached to a locking element and a second end for compression of said wireless receiver, and when said second end is compressed by said wireless receiver toward said first end, a resilient force is established against said wireless receiver, and when said snap-on element releases said wireless receiver, resilient force of said spring element will eject said wireless receiver out of said insertion slot so that a user could easily remove said wireless receiver, said bottom seat has a protruding tenon in a rear section of said bottom seat for embedding into a central through opening of said snap-on element, said bottom seat has a pair of positioning pins for holding said snap-on element therebetween, said snap-on element has a vertical blade extended into said receptacle chamber via a through opening configured at a bottom of said receptacle chamber, a corresponding groove is provided on a surface of said wireless receiver for embedding of said vertical blade when said wireless receiver is inserted into said receptacle chamber, said vertical blade is surrounded by a U-shape cutting such that said vertical blade can swing up and down flexibly, and when said wireless receiver is inserted into said receptacle chamber, said vertical blade of said snap-on element is pushed downward until said groove of said wireless receiver is on a top of said vertical blade, and at that instant, said vertical blade is extended into said groove and thereby positions and locks said wireless receiver inside said receptacle chamber, a release button is configured at a bottom of said snap-on element is pressed and, with a protruding tenon as a pivot point, said vertical blade is moved downward to leave the groove thereby removing said wireless receiver and therefore causing resilient force of said spring element to eject said wireless receiver out of said receptacle chamber, said release button is exposed by and hid inside a concaved button groove so that said release button wouldn't get in way of sliding operation of said wireless mouse, a built-in chargeable battery, and a jack is provided for connecting said chargeable battery to an external power source for recharging.
