A through hole is provided in the shell 1, which passes through both ends of the shell 1, and the through hole is coaxially arranged with the shell 1. A fixing sleeve 2 is fixedly arranged in the through hole in the shell 1, and the fixing sleeve 2 is also a cylindrical structure. The length of the fixing sleeve 2 is smaller than the length of the shell 1, one end of the fixing sleeve 2 is flush with one end of the shell 1, and the other end of the fixing sleeve 2 is located in the shell 1. A connecting head 3 is provided at the end of the fixing sleeve 2 flush with the shell 1, and the connecting head 3 extends to the outside of the shell 1. The connecting head 3 is connected with the inside of the fixing sleeve 2, and the outer wall of the connecting head 3 is provided with an external thread, which is connected to an external water pipe, and the other end of the fixing sleeve 2 is an open end, and the inside of the fixing sleeve 2 is a hollow structure. A water outlet pipe 4 is slidably arranged in the fixing sleeve 2, and the length of the water outlet pipe 4 is greater than the length of the fixing sleeve 2. The end of the water outlet pipe 4 located in the fixing sleeve 2 is a water inlet end, and the inlet of the water outlet pipe 4 The water end is located at one side of the connector 3, so the water outlet pipe 4 and the connector 3 are in a connected state, and the water flow can flow normally. The other end of the water outlet pipe 4 is a closed structure, and a plurality of water outlet holes 5 are opened on the side wall of the water outlet pipe 4. In the present invention, when the shower head is installed, the connector 3 can be threadedly connected to the external water pipe, and a sealing ring is provided at the bottom of the connector 3 to prevent water leakage. After the connection is completed, when taking a shower, the water outlet pipe 4 can be pulled out from the shell 1 and the fixing sleeve 2, so that the water outlet holes 5 extend to the outside of the shell 1. After opening the water pipe, the water flow can enter the water outlet pipe 4 through the connector 3 and be discharged from the water outlet holes 5 on the side wall of the water outlet pipe 4 for flushing and showering. After use, the water outlet pipe 4 is retracted into the shell 1 to reduce the size of the shower head, and the shower head can be unscrewed from the water pipe and put into the suitcase, which is convenient for storage and easy to carry. At the same time, the shower head is a cylindrical structure, and the size is also more compact, occupying less space.

[0034] Furthermore, if Figure 3 and Figure 6As shown, a bottom plate 7 is provided at the water inlet end of the water outlet pipe 4, and the bottom plate 7 is provided at one end of the water outlet pipe 4 close to the connector 3. A water inlet is provided on the bottom plate 7, and water can flow into the water outlet pipe 4 from the water inlet. A filter element 6 is provided in the water outlet pipe 4. The filter element 6 can be made of filter cotton, activated carbon filter element or polypropylene filter element purchased on the market, and other materials that can be used for filtering water. The filter element 6 is a cylindrical structure, and the length of the filter element 6 is less than the length of the water outlet pipe 4. The filter element 6 is located close to the water inlet. On one side of the outlet, the diameter of the filter element 6 is smaller than the inner diameter of the water outlet pipe 4, so a certain gap is left between the filter element 6 and the inner wall of the water outlet pipe 4 for the passage of water flow. An inlet channel 8 is provided inside the filter element 6. Water flows from the outside of the filter element 6 and passes through the filter element 6 for filtration before entering the inlet channel 8. Support frames 9 and connecting frames 10 are connected to both ends of the filter element 6. The support frame 9 is located on the side close to the connector 3. The support frame 9 is used to close one end of the filter element 6 so that water flow cannot flow from the support frame 9. One end enters the water inlet channel 8, the diameter of the support frame 9 is smaller than the inner diameter of the water inlet pipe 4, so there is a certain gap between the support frame 9 and the inner wall of the water outlet pipe 4, and the support frame 9 is provided with a support leg 11, and the support leg 11 abuts against the bottom plate 7, so there is a certain gap between the support leg 11 and the bottom plate 7, and the connecting frame 10 is connected to the support pipe 12, and the side wall of the support pipe 12 is provided with a plurality of water outlet grooves 13, and the water outlet grooves 13 correspond to the positions of the water outlet holes 5, and the support pipe 12 is connected to the water inlet channel 8 through the connecting frame 10 In this embodiment, after the water flows in through the connector 3, it can enter from the water inlet of the water inlet pipe 4, and then flow from the gap between the bottom plate 7 and the support leg 11 to the gap between the filter element 6 and the water outlet pipe 4. Then the water flows through the side wall of the filter element 6 and enters the water inlet channel 8. The filter element 6 can filter the water in this process. The water in the water inlet channel 8 finally flows into the support pipe 12 and is discharged from the water outlet groove 13, and finally discharged from the water outlet hole 5. The water outlet groove 13 can make the water flow of the outlet water more uniform.

[0035] Furthermore, a groove is provided on the outer wall of the water outlet pipe 4, and a sealing ring is provided in the groove. The sealing ring abuts against the inner wall of the fixing sleeve 2. Since the sealing ring is made of rubber material, there is a large friction force. While sealing and waterproofing between the water outlet pipe 4 and the fixing sleeve 2, it can also play a fixing role. After the water outlet pipe 4 is pulled out or retracted into the fixing sleeve 2, the water outlet pipe 4 is prevented from moving inside the fixing sleeve 2.

[0038] Furthermore, if Figure 2 As shown, the support tube 12 is provided with a mounting sleeve 32, the mounting sleeve 32 is a cylindrical structure, the mounting sleeve 32 has a cavity inside, one end of the mounting sleeve 32 is an open end, and the other end is provided with a sealing plate 33, the sealing plate 33 is provided with a flow hole 34, the open end of the mounting sleeve 32 is in contact with the connecting frame 10, and the support tube 12 is also provided with an aromatherapy box 36, the aromatherapy box 36 is filled with essential oil, the open end of the aromatherapy box 36 is in contact with the sealing plate 33, and the aromatherapy box 36 and the mounting sleeve 32 are connected through the flow hole. The mounting sleeve 32 is connected with the mounting sleeve 32 through the water hole 35. The water after being filtered by the filter element 6 enters the cavity in the mounting sleeve 32 through the connecting frame 10, and is mixed with the essential oil flowing into the mounting sleeve 32 from the aromatherapy box 36. Then, the water is discharged from the mounting sleeve 32 through the water hole 35 and enters the supporting tube 12. The water entering the supporting tube 12 enters the water outlet pipe 4 through the water outlet groove 13, and is finally discharged from the water outlet hole 5 for flushing and showering.

[0039] It should be noted that the connecting frame 10 is provided with a water passage, and the water filtered by the filter element 6 can flow from the water inlet channel 8 through the water passage on the connecting frame 10 and then enter the installation sleeve 32. A sealing ring is sleeved on the outer wall of the connecting frame 10, and the sealing ring abuts against the side wall of the water outlet pipe 4, which can prevent the water discharged from the support tube 12 from flowing into the gap between the filter element 6 and the water outlet pipe 4 again for filtering again, thereby avoiding a reduction in the water output of the shower.

[0040] Furthermore, a front cover 14 is connected to the side of the water outlet pipe 4 away from the water inlet end, and the front cover 14 is threadedly connected to one end of the water outlet pipe 4.
