     FIELD OF THE DISCLOSURE 
     The present disclosure relates to sanitary products, and in particular to a shower device. 
     BACKGROUND OF THE DISCLOSURE 
     The traditional beauty shower usually uses water as an exchange medium, introduces the water into a storage cavity configured for storing a beauty solution, and mixes the beauty solution with the water by means of displacement reaction. During the displacement reaction, a concentration of the beauty solution is larger in an early stage, and as the water flows into the storage cavity for the beauty solution in a later stage, the concentration released into the water will become weaker and weaker. 
     Traditional beauty product suction devices are powered by electricity, which consumes energy and requires electronic components such as motors and lithium batteries, and the cost is relatively high. 
     BRIEF SUMMARY OF THE DISCLOSURE 
     The present disclosure provides a beauty shower to enable a mixed ratio of liquid beauty medium to water to always be kept constant. 
     In order to solve the technical problem, a first technical solution of the present disclosure is as follows. 
     A beauty shower comprises a shower body. The shower body comprises a water flow passage connected to a water inlet port and a water outlet nozzle and a cavity for storing a liquid beauty medium. The cavity is connected to the water flow passage through a liquid suction device. The shower body further comprises a water flow driving device configured to drive the liquid suction device to pump the liquid beauty medium to the water flow passage. 
     In a preferred embodiment, the water flow driving device comprises a water diversion body and an impeller which are disposed in the water flow passage, and a flow direction of water in the water flow passage is configured to be changed by the water diversion body so as to enable the impeller to be driven to rotate. 
     In a preferred embodiment, the liquid suction device is a diaphragm pump. A liquid inlet port of the liquid suction device is connected to the cavity, and a liquid outlet port of the liquid suction device is connected to the water flow passage. A piston of the diaphragm pump is connected to the impeller through an eccentric mechanism. 
     In a preferred embodiment, the liquid inlet port is connected to the cavity through a flexible tube. 
     In a preferred embodiment, an adjusting device for adjusting a liquid suction volume is provided, and the adjusting device is configured to change an inner diameter of the flexible tube. 
     In a preferred embodiment, the adjusting device comprises a roller and a pressing block disposed on the roller, and the roller is configured to be rotated to change a squeezing degree of the pressing block to the flexible tube to change the inner diameter of the flexible tube. 
     In a preferred embodiment, the shower body further comprises an opening in communication with the cavity and a cover plate for opening or closing the opening.

     Compared with the existing techniques, the technical solution has the following advantages. 
     The present disclosure provides the beauty shower comprising the water flow driving device configured to drive the liquid suction device to pump the liquid beauty medium to the water flow passage, and extra electrical energy does not need to be consumed to enable energy saving and environmental protection. In addition, when a flow rate of water in the water flow passage does not change, a rotation speed of the water flow driving device is constant, which makes a ratio of the liquid beauty medium to the water always be constant. When the flow rate of the water in the water flow passage decreases, the rotation speed of the water flow driving device will decrease, and a corresponding amount of the liquid beauty medium mixed into the water will also decrease. Similarly, when the flow rate of the water in the water flow passage increases, the rotation speed of the water flow driving device will increase, and the corresponding amount of the liquid beauty medium mixed into the water will also increase accordingly. In this way, when the flow rate of water changes, an amount of the liquid beauty medium also changes correspondingly, so that the ratio of the liquid beauty medium to the water is substantially kept constant. The present disclosure provides the cavity for storing the liquid beauty medium detachably disposed on a back of the shower body and located above the water outlet nozzle. Replacement of the liquid beauty medium is facilitated, an inner space of the shower body is fully utilized, and the shower body is more compact.

     In the description of the present disclosure, it should be noted that the terms “installed”, “provided with”, “sleeved/connected”, “connected”, etc., should be understood broadly. For example, “connected” can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium, and it can be a connection between two members. For those of ordinary skill in the art, the specific meaning of the above terms in the present disclosure can be understood under specific conditions. 
     Referring to  FIGS.  1 - 3   , a beauty shower comprises a shower body  1 , and the shower body  1  comprises a water flow passage  13  connected to a water inlet port  11  and a water outlet nozzle  12  and a cavity  14  for storing a liquid beauty medium. 
     The cavity  14  is connected to the water flow passage  13  through a liquid suction device  3 . The shower body  1  further comprises a water flow driving device  2  configured to drive the liquid suction device  3  to pump the liquid beauty medium to the water flow passage  13 . 
     In the beauty shower, the water flow driving device  2  is used to drive the liquid suction device  3  to pump the liquid beauty medium in the cavity  14  into the water flow passage  13 , which does not require energy consumption, saves energy, and protects the environment. In addition, when a flow rate of water in the water flow passage  13  does not change, a rotation speed of the water flow driving device  2  is constant, which makes a ratio of the liquid beauty medium to the water always be constant. When the flow rate of the water in the water flow passage  13  decreases, the rotation speed of the water flow driving device  2  will decrease, and a corresponding amount of the liquid beauty medium mixed into the water will also decrease. Similarly, when the flow rate of the water in the water flow passage  13  increases, the rotation speed of the water flow driving device  2  will increase, and the corresponding amount of the liquid beauty medium mixed into the water will also increase accordingly. In this way, when the flow rate of water changes, an amount of the liquid beauty medium also changes correspondingly, so that the ratio of the liquid beauty medium to the water is substantially kept constant. 
     In the above-mentioned embodiment, the water flow driving device  2  comprises a water diversion body  21  and an impeller  22  disposed in the water flow passage  13 . A flow direction of the water in the water flow passage  13  is changed by the water diversion body  21  so as to drive the impeller  22  to rotate. The liquid suction device  3  is a diaphragm pump, a liquid inlet port  31  of the liquid suction device  3  is connected to the cavity  14 , and a liquid outlet port  32  of the liquid suction device  3  is connected to the water flow passage  13 . A piston of the diaphragm pump is connected to the impeller  22  through an eccentric mechanism. When the impeller  22  rotates, the impeller  22  will drive the eccentric mechanism to rotate, and the eccentric mechanism transfers an eccentric rotation to movement of the piston along an axial direction of the diaphragm pump. The structure of the diaphragm pump is in the prior art and is not expanded upon too much in this embodiment. 
     In this embodiment, the liquid inlet port  31  is connected to the cavity  14  through a flexible tube  33 . In order to further facilitate a user adjusting a pumping volume of the liquid beauty medium by himself, an adjusting device  4  for adjusting a liquid suction volume is provided, and the adjusting device  4  is used to change an inner diameter of the flexible tube  33 . 
     Specifically, the adjusting device  4  comprises a roller  41  and a pressing block  42  disposed on the roller  41 , and the roller  41  is rotated to change a squeezing degree of the pressing block  42  to the flexible tube  33  to change the inner diameter of the flexible tube  33 . When the user feels that the pumping amount of the liquid beauty medium is too large, the user only needs to turn the roller  41  by hand to drive the pressing block  42  to further squeeze the flexible tube  33  to make the inner diameter of the flexible tube  33  smaller. A housing of the shower body  1  comprises a through groove for exposing the roller  41 , and an indicator “+” and an indicator “−” are respectively provided on an upper end and a lower end of the through groove, which are used to instruct the user to rotate the roller  41  in a “+” direction (i.e., rotates toward the indicator “+”) to increases the pumping amount of the liquid beauty medium or in a “−” direction (i.e., rotates toward the indicator “−”) to decrease the pumping amount of the liquid beauty medium. 
     At the same time, in order to improve stability of the pumping amount of the liquid beauty medium to enable the roller  41  not to roll when there is no manual manipulation, the adjusting device  4  further comprises an elastic positioning pin  43 , and the roller  41  comprises a plurality of positioning grooves along a rolling direction of the roller  41 . When the roller  41  is not manually moved, the elastic positioning pin  43  is buckled to one of the plurality of positioning grooves to inhibit movement of the roller  41  along a rotation direction of the roller  41 . 
     In addition, in order to facilitate supplying of the liquid beauty medium, the shower body  1  further comprises an opening in communication with the cavity  14  and a cover plate  15  for opening or closing the opening. In this embodiment, the opening is defined on a side wall of a front end portion of the shower body  1 , and one end of the cover plate  15  is rotatably connected to the front end portion of the shower body  1 . 
     In order to achieve sealing of the opening by the cover plate  15 , a plug  151  for being inserted into the opening is disposed on a side of the cover plate  15  facing the opening, and a sealing ring  152  is disposed on a side wall of the plug  151 . 
     Finally, a side wall of the cavity  14  further comprises a ventilation port in communication with outside atmosphere, and a check valve  141  is disposed on the ventilation port. Air pressure balance between the cavity  14  and the outside atmosphere can be ensured through the ventilation port, and there will be no negative pressure in the cavity  14  after the liquid beauty medium is consumed. The purpose of providing the check valve  141  is to prevent the liquid beauty medium from flowing out of the ventilation port. 
     In this embodiment, the cavity  14  for storing the liquid beauty medium is detachably disposed on a back of the shower body  1  and located above the water outlet nozzle  12 . Replacement of the liquid beauty medium is facilitated, an inner space of the shower body  1  is fully utilized, and the shower body  1  is more compact. 
     In this embodiment, switching between shower water and beauty water can also be conveniently achieved by adjusting the adjusting device  4 . 
     In this embodiment, the liquid beauty medium may be essential oil, shower gel, shampoo, or essence. The aforementioned embodiments are merely some embodiments of the present disclosure, and the scope of the disclosure is not limited thereto. Thus, it is intended that the present disclosure cover any modifications and variations of the presently presented embodiments provided they are made without departing from the appended claims and the specification of the present disclosure.
