Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one such feature.

[0032] Reference Figures 1 to 10 The present invention provides an aromatherapy shower head, comprising a shower head body 1 and a handle 2. A spray hole 102 is provided on the shower head body 1. A main channel 105 for water flow is provided in the shower head body 1. An auxiliary channel is provided in the shower head body 1. Both the upstream and downstream ends of the auxiliary channel are connected to the main channel 105. A pressurizing structure is provided in the shower head body 1 to make the water pressure at the upstream end of the auxiliary channel greater than the water pressure at the downstream end. An aromatherapy container 5 is provided in the auxiliary channel. The aromatherapy container 5 contains aromatherapy, which is in liquid form, a paste similar to toothpaste, or a semi-fluid similar to yogurt. A fragrance outlet 51 and a sealing structure for closing the fragrance outlet 51 are provided at the downstream end of the aromatherapy container 5. The aromatherapy container 5 is also provided with an extrusion member. When the fragrance outlet 51 is opened and water flows into the shower head body 1, the extrusion member is deformed by the water pressure or moves in the aromatherapy container 5 to squeeze out the aromatherapy container 5.

[0033] Example 1

[0034] Figures 1 to 8 The embodiment 1 of the present invention is shown. In this embodiment, an opening 52 is provided at the upstream end of the aromatherapy container 5. The extrusion member is an elastic film 53 provided at the opening 52. The elastic film 53 is made of a highly elastic rubber material similar to that of a balloon.

[0035] Before showering with the showerhead of this embodiment, the sealing membrane 54 on the fragrance container 5 needs to be punctured. During showering, tap water enters the shower head 11 through the handle 2. Due to the pressure boosting structure, the water pressure at the upstream end of the auxiliary channel is greater than the water pressure at the downstream end. Under the action of this pressure difference, the elastic film 53 is deformed toward the interior of the fragrance container 5, and the fragrance in the fragrance container 5 is gradually squeezed out from the downstream end of the auxiliary channel, evenly mixed into the water flow of the main channel, and finally sprayed out from the spray hole 102. Throughout the shower process, the ratio of fragrance to water fluctuates slightly, which can prevent the fragrance from becoming significantly diluted.

[0036] In this embodiment, the boosting structure includes a converging section 1051 that gradually narrows along the water flow direction. Converging section 1051 forms part of the main channel 105. The upstream end opening of the auxiliary channel is located upstream or in the middle of converging section 1051, and the downstream end opening of the auxiliary channel is located downstream of converging section 1051. This design of the boosting structure is simple and effective.

[0037] The sealing structure is a sealing film 54 provided at the fragrance outlet 51. The shower body 1 includes a shower head 11 and an openable and closable cover 12. The auxiliary channel includes a mounting groove 101 provided on the upper surface of the shower head 11 with the groove facing upward, a water inlet 103 located upstream of the mounting groove 101, and a fragrance outlet pipe 104 located downstream of the mounting groove 101. The fragrance container 5 is installed in the mounting groove 101. The head end of the fragrance outlet pipe 104 is located at the bottom of the mounting groove 101 and is directly opposite the fragrance outlet 51 of the fragrance container 5. The head end of the fragrance outlet pipe 104 is provided with a pointed tip that can pierce the sealing film 54 when the fragrance container 5 is installed in the mounting groove 101. With this design, when the fragrance container 5 is installed in the mounting groove 101, the pointed tip of the fragrance outlet pipe 104 pierces the sealing film 54 on the fragrance container 5 and is inserted into the fragrance container 5, eliminating the need for a separate operation to pierce the sealing film 54, which is convenient and quick.

[0038] Reference Figure 1 The lower end of the water inlet 103 is connected to the main channel 105, and the upper end of the water inlet 103 is exposed on the upper surface of the shower head 11 and is connected to the notch of the mounting groove 101. When the cover body 12 is in the closed state, the mounting groove 101 and the water inlet 103 are shielded. A sealing structure that surrounds the upper end of the water inlet 103 and the notch of the mounting groove 101 is provided between the cover body 12 and the shower head 11. A locking structure that can lock the cover body 12 and the shower head 11 is also provided between the cover body 12 and the shower head 11 to keep the cover body 12 in the closed state.

[0039] In this embodiment, the sealing structure includes a sealing groove 106 arranged around the notch of the installation groove 101 and a sealing ring 6 installed in the sealing groove 106 .

[0040] Furthermore, one side of the cover 12 is hingedly connected to the shower head 11. The locking structure includes a buckle 107 provided on the shower head 11, and an elastic buckle device provided on the cover 12 and capable of buckling with the buckle 107. The cover 12 is also provided with a pressing member 3 that can push the elastic buckle device to disengage the buckle 107. When installing the aromatherapy diffuser, pressing the pressing member 3 pushes the elastic buckle device to disengage the elastic buckle device from the buckle 107 of the shower body. The cover 12 can then be opened, the aromatherapy diffuser installed in the installation slot 101, and the cover 12 is closed again, so that the elastic buckle device is buckled with the buckle 107 of the shower body. When using the aromatherapy diffuser for showering, the cover 12 can provide a certain degree of waterproofing. When the aromatherapy diffuser needs to be replaced, the cover 12 is opened, the used aromatherapy diffuser is removed, a new one is installed, and the cover 12 is closed again. The entire process of disassembling and assembling the aromatherapy diffuser is very convenient and quick.

[0041] In a preferred solution of this embodiment, the elastic fastening device includes a fastener 41 that is movably arranged on the inner side of the cover body 12, and the lower part of the pressing member 3 is provided with a pushing inclined surface 301 that can drive the fastener 41 to move backward and disengage from the fastening position 107 when the pressing member 3 moves. The elastic fastening device also includes an elastic member 42 that can drive the fastener 41 to reset forward by elastic force.

[0042] The pressing member 3 can be configured to be movable up and down or rotatable. The push inclined surface 301 provided on the pressing member 3 can change the direction of force transmission, so that the pressing member 3 can drive the fastener 41 to move backward when it moves up and down or rotates up and down. This design can improve the compactness of the cover body 12 and occupy less space.

[0043] In a preferred embodiment of this embodiment, the cover 12 is provided with a guide groove 203 for the fastener 41 to move forward and backward. The front end of the fastener 41 is provided with a snap-fit ​​portion 411 that extends beyond the guide groove 203. The elastic member 42 is a spring disposed between the rear end of the fastener 41 and the cover 12. The mounting groove 101 is provided on the upper surface of the shower head 11. The upper surface of the shower head 11 is also provided with a receiving groove 108 for the snap-fit ​​portion 411 to be inserted into. The snap-fit ​​position 107 is a boss provided on the front inner wall of the receiving groove 108. The rear end of the pressing member 3 is hinged to the cover 12, and the push-up slope 301 is provided on the front portion of the pressing member 3.

[0044] In order to smoothly transmit the thrust between the pressing member 3 and the fastener 41 , the fastener 41 is provided with a thrust-bearing inclined surface 412 that cooperates with the thrust-bearing inclined surface 301 .

[0045] Example 2

[0046] Figure 9 and Figure 10Example 2 of the present invention is shown. This example has a similar structure to Example 1, but differs in that it further incorporates the following structure: a one-way valve is provided within the water inlet 103 to prevent water flowing into the water inlet 103 from the main channel 105 from flowing back into the main channel 105. This design has the advantage that when the water pressure at the source is unstable, the one-way valve can maintain pressure, ensuring that a relatively stable water pressure is maintained at the water inlet 103 and the notch of the mounting slot 101, thereby achieving continuous and stable aromatherapy output.

[0047] In this embodiment, the lower end of the water inlet 103 is connected to the main channel 105, and the upper end of the water inlet 103 is connected to the installation groove 101. The water inlet 103 includes a first hole section 1031, a second hole section 1032 and a third hole section 1033 arranged in sequence from bottom to top. The diameter of the second hole section 1032 is larger than the diameter of the third hole section 1033 so that a limiting step 109 is formed between the two. The first hole section 1031 is a conical hole that gradually expands from bottom to top and the diameter of the upper end of the first hole section 1031 is smaller than the diameter of the second hole section 1032. The one-way valve includes a plug 71 pressed on the conical surface of the second hole section 1032, and a spring 72 installed between the plug 71 and the limiting step 109. The plug 71 is pressed against the conical surface of the second hole section 1032 by the elastic force of the spring 72.

[0048] In both Examples 1 and 2 above, the extrusion member is an elastic film 53. Furthermore, the extrusion member may also adopt other structural forms, for example, the extrusion member may be designed as a piston that can move within the fragrance container 5. When water is flowing through the shower head, the water pressure drives the piston to move, squeezing out the fragrance within the fragrance container 5.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. All equivalent structural transformations made based on the contents of the present invention's description and drawings, or directly or indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
