Description

Technical Field

[0001] The present invention relates to the technical field of shower products, and in particular to an aromatherapy release structure and a shower head. Background Art

[0002] Showerheads are nozzles used for showers and are one of the most important tools in the bathing process. As people's living standards improve, they have higher requirements for bathing experience. It is no longer just a simple shower and cleansing, but also requires a variety of experiences such as massage, beauty, and aromatherapy.

[0003] To enhance the bathing experience, showerheads that mix fragrance and water before spraying them out have gradually appeared on the market. Patent publication number CN115106209A discloses an aromatherapy showerhead. This showerhead incorporates an internal pressurization structure, which increases the water pressure on one side of the aromatherapy container to be greater than the other. This high water pressure then compresses an elastic film, causing it to deform and squeeze the fragrance out of the container and mix it into the shower water. This showerhead also has the following problems: First, the elastic film has very high requirements for high elasticity and durability, which leads to very high production costs for the aromatherapy container.

[0004] The present invention is made based on this situation. Summary of the Invention

[0005] In view of this, one of the objectives of the present invention is to provide an aroma release structure for use in a shower head that can reduce the production cost and installation cost of an aroma container. Under the water flow pressure in the shower head, the aroma inside the aroma container can be automatically and slowly released into the water flow to produce aromatherapy shower water.

[0006] A second object of the present invention is to provide a shower head having the above-mentioned aroma release structure.

[0007] The technical solution adopted by the present invention to solve the technical problem is:

[0008] An aromatherapy release structure includes a shower head, wherein a main channel for water to flow through is provided in the shower head, and a bell-mouth section that gradually widens along the direction of water flow is provided in the main channel. The shower head is also provided with a mounting groove located above the main channel and an auxiliary channel that connects the main channel and the mounting groove. A fragrance outlet channel connected to the main channel is provided at the bottom of the mounting groove, and the outlet of the fragrance outlet channel is located at the bell-mouth section or downstream of the bell-mouth section, and the inlet of the auxiliary channel is located upstream of the bell-mouth section. An aromatherapy container is installed in the mounting groove, and the aromatherapy container contains liquid aromatherapy. An openable structure is provided at the bottom of the aromatherapy container. When the openable structure is opened and water flows in the shower head, a water pressure difference is generated between the fragrance outlet channel and the auxiliary channel to suck the aromatherapy container out of the fragrance outlet channel.

[0009] As a further optimization of the above technical solution, a fragrance outlet tube is fixedly installed at the fragrance outlet channel, and the upper end of the fragrance outlet tube extends into the installation groove. The upper end of the fragrance outlet tube has a pointed tip that can pierce the openable structure when the aromatherapy container is installed in the installation groove.

[0010] As a further optimization scheme of the above technical scheme, the bottom of the aromatherapy container is provided with a downwardly protruding bulge, which forms a fragrance outlet groove in the aromatherapy container that is lower than the inner bottom surface of the aromatherapy container. The openable structure is provided on the bulge. After the pointed tip of the fragrance outlet tube pierces the openable structure of the aromatherapy container, the pointed tip of the fragrance outlet tube is located in the fragrance outlet groove and lower than the inner bottom surface of the aromatherapy container.

[0011] In a preferred embodiment of the present invention, the aromatherapy container is made of plastic, and the openable structure is a thin-walled portion provided on the convex bulge, and the thickness of the thin-walled portion is 1 / 4 to 1 / 2 of the thickness of the bottom wall.

[0012] In a preferred embodiment of the present invention, a fragrance outlet hole is provided on the bottom surface of the convex bag, and the openable structure is a sealing film provided at the fragrance outlet hole.

[0013] As a further optimization of the above technical solution, a boosting section that gradually narrows along the water flow direction is also provided in the main channel. The boosting section is located upstream of the bell-mouth section, and a narrow opening is formed between the boosting section and the bell-mouth section.

[0014] As a further optimization solution of the above technical solution, the outlet of the fragrance outlet channel is located in the middle of the bell-mouth section, and the ratio of the cross-sectional area of ​​the bell-mouth section at the outlet of the fragrance outlet channel to the cross-sectional area of ​​the narrow mouth is 2-100.

[0015] As a further optimization solution of the above technical solution, the shower head has a shower cavity, the bottom of the shower cavity is provided with a spray hole connected to the outside, and one end of the bell-mouth section is open in the shower cavity.

[0016] A shower head includes the above-mentioned aroma release structure, and also includes a cover body and a handle. The handle is fixed to the shower head, and the handle has a water inlet channel connected to the main channel. The opening of the mounting groove faces upward. The cover body is movably mounted on the shower head. When the cover body is in a closed state, the mounting groove is shielded. A first sealing ring arranged around the mounting groove is provided between the cover body and the shower head. A locking structure is also provided between the cover body and the shower head, which can lock the two to keep the cover body in a closed state.

[0017] As a further optimization solution of the above technical solution, a second sealing ring is provided between the aromatherapy container and the inner wall of the installation groove to separate the fragrance outlet channel from the auxiliary channel.

[0018] In a preferred embodiment of the present invention, the second sealing ring is provided on the bottom surface of the mounting groove, and the cover body is provided with a pressing block capable of pressing the aromatherapy container to tighten the second sealing ring.

[0019] The beneficial effects of the present invention are:

[0020] First, before using the shower head of the present invention for showering, it is necessary to puncture the opening structure on the aromatherapy container. During showering, the aromatherapy container is connected to the fragrance outlet channel, and tap water enters the main channel of the shower head from the handle. The tap water itself has a high water pressure, but when it passes through the bell-shaped section and enters the shower cavity, the water pressure will drop sharply, making the water pressure at the outlet of the fragrance outlet channel very low. Under the action of the suction force of this low-pressure area, the fragrance in the aromatherapy container will be sucked out little by little and evenly mixed into the water flow in the main channel, and finally the shower water containing the fragrance will be sprayed out from the spray hole.

[0021] Second, because the installation slot is located above the main channel, and the shower cavity is filled with air before showering, a large number of bubbles will be generated in the shower cavity after the water is turned on for showering. As the fragrance in the aromatherapy container flows out little by little, some of the bubbles will float upward to the installation slot and enter the aromatherapy container, so that the pressure in the aromatherapy container can be kept balanced and the fragrance can be continuously released.

[0022] Third, the aromatherapy container of the present invention can be directly made of hard plastic without the need for a highly elastic and durable elastic film, which is beneficial to reducing production costs. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0031] Reference Figures 1 to 6 A shower head with an aroma release structure includes a shower head 11, a handle 13 fixed to one side of the shower head 11, and a cover 12 installed on the shower head 11 in an openable and closable manner.

[0032] The shower head 11 is provided with a main channel 105 for water flow, and the main channel 105 is provided with a bell-mouth section 1051 that gradually widens along the direction of water flow. The shower head 11 is also provided with a mounting groove 101 located above the main channel 105 and an auxiliary channel 103 that connects the main channel 105 and the mounting groove 101. The bottom of the mounting groove 101 is provided with a fragrance outlet channel 104 that is connected to the main channel 105. The outlet of the fragrance outlet channel 104, that is, the end of the fragrance outlet channel 104 that is connected to the main channel is located at the bell-mouth section 1051 or at the bell-mouth section 105. Downstream of the mouth section 1051, the entrance of the auxiliary channel 103, that is, the end of the auxiliary channel 103 connected to the main channel is located upstream of the bell-mouth section 1051. An aromatherapy container 5 is installed in the mounting groove 101. The aromatherapy container 5 contains aromatherapy, which is a liquid or a semi-fluid similar to yogurt. The bottom of the aromatherapy container 5 is provided with an openable structure. When the openable structure is opened and water flows into the shower head 11, a water pressure difference is generated between the fragrance outlet channel 104 and the auxiliary channel 103 to suck the aromatherapy container 5 out of the fragrance outlet channel 104.

[0033] The shower head 11 has a shower cavity 107 . A spray hole 102 communicating with the outside is provided at the bottom of the shower cavity 107 . One end of the bell-mouth section 1051 is open in the shower cavity 107 .

[0034] The handle 13 has a water inlet channel 131 connected to the main channel 105. The opening of the mounting groove 101 faces upward. The cover 12 is movably mounted on the shower head 11. When the cover 12 is in the closed state, the mounting groove 101 is shielded. A first sealing ring 6 is provided between the cover 12 and the shower head 11, which is arranged around the mounting groove 101. A locking structure is also provided between the cover 12 and the shower head 11, which can lock the two to keep the cover 12 in the closed state.

[0035] Preferably, one side of the cover 12 is hingedly connected to the shower head 11. The locking structure includes a buckle 108 provided on the shower head 11 and an elastic buckle 41 provided on the cover 12 and capable of buckling with the buckle 108. The cover 12 is also provided with a pressing member 3 that can push up the elastic buckle 41 to disengage it from the buckle 108. When installing the aromatherapy diffuser, pressing the pressing member 3 pushes up the elastic buckle 41 to disengage it from the buckle 108 of the shower body. The cover 12 can then be opened, the aromatherapy container 5 installed in the installation slot 101, and the cover 12 can be closed again, so that the elastic buckle 41 is buckled into the buckle 108 of the shower body. 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.

[0036] Before using the shower head of the present invention for showering, it is necessary to puncture the openable structure on the fragrance container 5. During showering, the fragrance container 5 is connected to the fragrance outlet channel 104, and tap water enters the main channel 105 of the shower head 11 from the handle 13. The tap water itself has a high water pressure, but the water pressure drops sharply as it passes through the bell-mouth section 1051 and enters the shower chamber 107. The outlet of the fragrance outlet channel 104 is located at the bell-mouth section 1051 or downstream of the bell-mouth section 1051, and the inlet of the auxiliary channel 103 is located upstream of the bell-mouth section 1051. As a result, the water pressure at the outlet of the fragrance outlet channel 104 is very low. Under the action of the suction force of this low-pressure area, the fragrance in the fragrance container 5 is sucked out bit by bit and evenly mixed into the water flow in the main channel 105, and finally the shower water containing the fragrance is sprayed out from the spray hole 102. In addition, since the mounting groove 101 is located above the main channel 105, and the shower cavity 107 is filled with air before showering, a large number of bubbles will be generated in the shower cavity 107 after the water is turned on for showering. As the fragrance in the fragrance container 5 flows out little by little, some of the bubbles will float upward to the mounting groove 101 and enter the fragrance container 5, so that the pressure in the fragrance container 5 can be kept balanced and the fragrance can be continuously released.

[0037] In a preferred embodiment of the present invention, a fragrance outlet tube 106 is fixedly mounted in the fragrance outlet passage 104. The upper end of the fragrance outlet tube 106 extends into the mounting slot 101. The upper end of the fragrance outlet tube 106 has a pointed tip that can pierce the opening structure when the fragrance container 5 is inserted into the mounting slot 101. With this design, when the fragrance container 5 is inserted into the mounting slot 101, the pointed tip of the fragrance outlet tube 106 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. This is a convenient and quick design.

[0038] Reference Figure 5 and Figure 6 The aromatherapy container 5 has two structural forms. Figure 5The structure of a first type of aromatherapy container 5 is shown. Made of hard plastic, the container 5 has a downwardly protruding bump 51 at its bottom. This bump 51 forms a fragrance outlet 511 within the container 5, lower than the inner bottom surface. The opening is a thin-walled portion 52 located on the bump 51. The thickness of the thin-walled portion 52 is 1 / 4 to 1 / 2 the thickness of the bottom wall. This design allows the thin-walled portion 52 to be conveniently and quickly integrally injection-molded with the bottom and side walls of the container 5. The top wall can be formed separately and then bonded or welded to the side walls.

[0039] Figure 6 The structure of the second aromatherapy container 5 is shown. This aromatherapy container 5 has a similar structure to the first aromatherapy container 5. The only difference lies in the specific structure of the openable structure. In this solution, the bottom surface of the convex bulge 51 is provided with a fragrance outlet hole, and the openable structure is a sealing film 54 provided at the fragrance outlet hole.

[0040] Reference Figure 3 After the tip of the fragrance tube 106 pierces the openable structure of the fragrance container 5, it is located in the fragrance outlet slot 511 and below the inner bottom surface of the fragrance container 5. With this design, most of the fragrance in the fragrance container 5 can be used up, and only a small amount of fragrance in the fragrance outlet slot 511 below the tip of the fragrance tube 106 may not be used up.

[0041] In a preferred embodiment of the present invention, a pressurizing section 1052 that gradually narrows along the direction of water flow is further provided in the main channel 105. The pressurizing section 1052 is located upstream of the bell-mouth section 1051, and a narrow opening 1053 is formed between the pressurizing section 1052 and the bell-mouth section 1051. The outlet of the fragrance outlet channel 104 is located in the middle of the bell-mouth section 1051, and the inlet of the auxiliary channel 103 is located in the pressurizing section 1052. The ratio of the cross-sectional area of ​​the bell-mouth section 1051 at the outlet of the fragrance outlet channel 104 to the cross-sectional area of ​​the narrow opening 1053 is 2-100. With such a design, the water pressure at the inlet of the auxiliary channel 103 can be greater than the water pressure at the narrow opening 1053, and the water pressure at the narrow opening 1053 can be greater than the water pressure at the outlet of the fragrance outlet channel 104. Such a design further increases the pressure difference between the outlet of the fragrance outlet channel 104 and the auxiliary channel 103, making it more conducive to drawing out the fragrance in the fragrance container 5.

[0042] Furthermore, a second sealing ring 2 is disposed between the aromatherapy container 5 and the inner wall of the mounting groove 101, separating the fragrance outlet passage 104 from the auxiliary passage 103. Specifically, the second sealing ring 2 is disposed on the bottom surface of the mounting groove 101, and a pressing block 121 is provided on the lid 12, which compresses the aromatherapy container 5 and thereby the second sealing ring 2. This design prevents direct communication between the fragrance outlet passage 104 and the auxiliary passage 103, which would otherwise reduce the pressure difference between the two.

[0043] 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.
