DETAILED DESCRIPTION

[0030] Various embodiments of the application will be described with reference to the drawings hereinafter. For convenience, the same components in the figures are denoted by same reference numerals. It should be understood that the terms front, back, left, right, up and down used in the following description refer to the directions in the figures, and the terms inner and outer refer generally to directions towards or away from geometric centers of specific parts, respectively.

[0031] Referring to FIGS. 1-3 and FIG. 9, a shower device according to an embodiment of the present application is shown. The shower device includes a spray head 1 and a massage assembly 2 that is removably coupled to the spray head 1.

[0032] The massage assembly 2 comprises a massage brush head 21 and a driving mechanism 22 for driving the massage brush head 21 to move (e.g., relative to the spray head 1).

[0033] The spray head 1 defines a mounting opening 110 (e.g., a mounting hole, etc.) therein. The driving mechanism 22 is insertable in the mounting opening 110. In some embodiments, the driving mechanism 22 is pluggably mounted into the mounting opening (e.g., is configured to plug into the mounting opening 110, etc.).

[0034] In at least one embodiment, the massage brush head 21 is removably coupled to an output shaft 220 of the driving mechanism 22. At least a portion of the massage brush head 21 protrudes from the spray head 1 (e.g., from a spray face of the spray head 1 as shown in FIG. 1 that includes nozzle openings of the spray head).

[0035] The shower device provides an integrated massage function via the removable massage assembly 2. As shown in FIG. 2, the mounting opening 110 is a central opening disposed in the middle of the spray head 1.

[0036] Referring to FIG. 2 and FIG. 3, in some embodiments, the massage assembly 2 includes a massage brush head 21 and a driving mechanism 22. The driving mechanism 22 is configured to drive the massage brush head 21 to rotate with respect to the spray head 1 and/or vibrate. The driving mechanism 22 may be a rotary driving mechanism and/or a vibration driving mechanism, etc. The rotary driving mechanism and/or vibration driving mechanism may be a rotary motor, a vibration motor, or a rotary vibration motor with both an integrated rotary function and vibration function. The driving mechanism 22 may employ a physical push button switch or a remote control signal switch to control activation thereof.

[0037] The driving mechanism 22 is removably coupled to the spray head 1 at the mounting opening 110. The driving mechanism 22 can be assembled into the mounting opening 110 in a pluggable way such as by snap-fitting, a threaded connection, a magnetic connection, etc., so that the driving mechanism 22 can be inserted into the mounting opening 110 or pulled out from the mounting opening 110 to be used independently from the spray head 1 as a standalone massager.

[0038] The output shaft 220 is disposed on a front side of the driving mechanism 22. As used herein, the front side refers to a side of the driving mechanism 22 facing a spray face of the spray head 1 through which water is delivered to a user, and the back side refers to the side facing away from the spray face.

[0039] The massage brush head 21 is disposed the front side of the spray head 1. A portion of the massage brush head 21 protrudes away from the spray head 1, forward of the spray head 1. The massage brush head 21 is removably coupled to the output shaft 220 of the driving mechanism 22. In some embodiments, the massage brush head 21 and the output shaft 220 are assembled together by snap-fitting, a threaded connection, etc., which allows for the replacement of the massage brush head 21 with different massage brush heads that provide different functions.

[0040] Referring to FIG. 9, massage brush head structures are shown, according to various embodiments.
