Title: Massage stick structure

Description:
BACKGROUND OF THE INVENTION 
     1. Technical Field 
     The technical field of this disclosure relates to a massage stick structure, and particularly relates to an easy-to-assemble massage stick structure. 
     2. Description of Related Art 
     Modern people pay more and more attention to maintain physical health with exercise and fitness and various kinds of soreness may occur. A massage stick or a massage chair is often used for massaging and relieving pressure, and the massage stick is used more extensively because of the features of low cost and convenience. 
     In general, the massage stick is assembled by installing the internal components into a casing first, and then assembling the casing to secure the structure. The related massage stick is difficult to be assembled and the assembling is time-consuming. Further, the non-integrally formed casing may have gaps and poor water resistance. Therefore, how to make the structure of the massage stick easy-to-assemble and have good water resistance is the problem that needs to be solved. 
     In view of the aforementioned drawbacks of the prior art, the discloser of the present disclosure based on years of experience in the related industry to conduct extensive research and experiment, and finally provided a feasible solution to overcome the drawbacks of the prior art. 
     SUMMARY OF THE INVENTION 
     It is a primary object of this disclosure to overcome the drawbacks of the prior art by providing an easy-to-assemble massage stick structure that simplifies the assembly process of each component, so as to reduce production time and maintenance time. 
     To achieve the aforementioned and other objectives, the present disclosure discloses an easy-to-assemble massage stick structure including a hollow cylinder, a drive control module, and an end cover. The hollow cylinder has a cavity and a mounting port formed on one end of the hollow cylinder and communicating with the cavity. The drive control module includes a support member, and a control assembly and a vibrator fixed to the support member. The end cover is fixed to the support member. The drive control module is disposed into the cavity from the mounting port, and the end cover is assembled to cover the mounting port. 
     This disclosure has the following functions. The massage stick has better water resistance with the integrally formed hollow cylinder. The upper end cover may be fixed on the opening by the hooks and snap slots. The end cover may be fixed on the mounting port by the fixing holes and locking holes. The hollow convex ring disposed on the bottom of the tray may provide a deep massage effect. The massage stick has the effects of heat compress and medical compress by the heating member and the dressing assembly.
