Background

Teeth are the hardest organs of the human body, and have the functions of keeping the facial appearance, assisting pronunciation and the like besides the functions of incising and chewing, and can be divided into 4 types of incisors (incisors), cuspids (tigers), premolars and molars. Each tooth is composed of a crown exposed outside an alveolar bone, a tooth root growing inside the alveolar bone and a neck between the crown and the tooth root, and the tooth mainly comprises dentin (dentin) and is externally coated with enamel (on the crown part) and cementum (on the root part). The cementum is also provided with periodontal ligament composed of fiber for fixing teeth in alveolus. The tooth center has pulp chamber, full of pulp, and abundant blood vessel and nerve, and tooth when daily use, need carry out health care treatment, including the most basic mouth wash, brush teeth and wash etc. and tooth when washing, will use the tooth flusher, and the tooth flusher is a clean oral auxiliary tool, utilizes the mode of pulse water impact to clean tooth, interdental space's a tool, mainly has portablely, the desk-top, generally washes pressure at 90 to 120 psi.

Most of tooth flushing devices in the existing market are simple in transmission structure design, most of the tooth flushing devices are transmission structures such as gears and fluted discs, the structure is multiple in structure, noise is high when the tooth flushing device is used, occupied space is large, and production cost cannot be effectively reduced, so that the cylindrical groove type cam is provided for solving the problems.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution:

cylindrical groove type cam, including cam body 1, cam body 1's the outside is equipped with two connecting rod pistons 2, and the inboard fixedly connected with slider of connecting rod of two connecting rod pistons 2, and the slider is hemispherical setting, two connecting rod pistons 2 are through slider and 1 sliding connection of cam body, rubber ring 3 has been cup jointed to two connecting rod pistons 2's the other end, spout 4 has been seted up on cam body 1's the lateral wall, and cam body 1 passes through spout 4 and slider and 2 sliding connection of two connecting rod pistons, axle sleeve hole 5 has been seted up to cam body 1's inboard, set up through the above-mentioned technique, not only can effectual noise reduction and manufacturing cost, and the effectual number and the process of part that has reduced, thereby the shared space of structure that reduces.

The two ends of the shaft sleeve hole 5 are arranged by adopting chamfers, the degree of the chamfers of the shaft sleeve hole 5 is 45 degrees, the arrangement is convenient for being installed on a motor for use, the chamfers are arranged on the outer side of the cam body 1, the chamfer setting of the outer side of the cam body 1 is the same as the chamfer setting of the inner side of the shaft sleeve hole 5, the structure is convenient to install and use, one side of the cross section of the chute 4 is arranged in a semicircular shape, the arrangement can lead the double-connecting-rod piston 2 to be well jointed with the cam body 1, the sliding chute 4 is annularly arranged, the front side and the rear side of the sliding chute 4 are equal in height, the left side and the right side of the sliding chute 4 are equal in height, the front and the back sides of the sliding groove 4 are higher than the left and the right sides of the sliding groove 4, the sliding groove 4 is in cambered surface transition arrangement, the arrangement ensures that the motor can well drive the double-connecting-rod piston 2 to slide back and forth through the cam body 1.
