Description

Technical Field

[0001] This utility model relates to the field of bathroom fixtures technology, and in particular to a multifunctional shower head. Background Technology

[0002] A showerhead, also known as a shower head, is a core component of a modern bathroom. Its basic function is to disperse water into various spray patterns suitable for showering through its water outlet structure. In addition to providing basic water showering, many showerhead products on the market also have a material collection function.

[0003] These types of showerheads typically have a cavity inside the handle to hold functional materials, such as filter cartridges for water purification, essential oil cartridges for releasing plant extracts, and herbal sachets for health benefits. These functional materials dissolve and release active ingredients or treat the water as it flows through, thus providing additional functions such as filtration, fragrance, and therapeutic effects, enhancing the bathing experience. However, these showerheads still have several significant shortcomings in actual use.

[0004] On the one hand, some disposable or short-lasting materials, such as medicine packets and fragrance blocks, have a short service life and need to be replaced frequently. However, the existing shower head disassembly and assembly steps are cumbersome and not convenient for users to replace them quickly.

[0005] On the other hand, taking medicated baths as an example, after using a medicated bath pack, it is usually necessary to shower again with clean water to rinse away any residual medicinal solution on the skin. However, most showerheads currently cannot achieve a quick and reliable switch between medicated bath mode and clean water shower mode, affecting the continuity and comfort of the bathing process. Utility Model Content

[0006] The purpose of this invention is to provide a multifunctional shower head that allows for quick switching between basic and additional functions.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A multi-functional shower head includes a handle and a spray head connected together. The handle has a hollow inner cavity. The spray head includes: a housing with an assembly cavity having a front opening inside, the assembly cavity having a water inlet communicating with the inner cavity of the handle; a reservoir disposed within the assembly cavity and avoiding the water inlet, the reservoir having a storage chamber inside, and an outlet and a immersion hole communicating with the storage chamber; a diverter seat rotatably mounted within the assembly cavity around a central axis, separating a diverter chamber between the housing and the reservoir; and a front cover disposed on the front side of the housing and closing the assembly cavity, the front cover having a first spray hole group and a second spray hole group, the first spray hole group communicating with the outlet, and the second spray hole group communicating with the diverter chamber. The diverter seat can be rotated to switch between different states. In the first state, the diverter cavity connects the water inlet and the immersion hole. In the second state, the diverter cavity connects the water inlet and isolates the immersion hole.

[0008] Furthermore, the storage device includes an inner sleeve and an outer sleeve nested together. The inner sleeve is provided with the water outlet, and the interior of the inner sleeve forms the storage cavity. The outer sleeve is provided with the immersion hole. A flow guiding layer is formed between the inner sleeve and the outer sleeve at an interval. The flow guiding layer is connected to the storage cavity on the side opposite to the water outlet.

[0009] Furthermore, the storage chamber is provided with a loading port for loading and unloading materials, and the nozzle also includes a rear cover, which is detachably connected to the rear side of the housing to open and close the loading port.

[0010] Furthermore, a cylindrical storage holder is provided inside the assembly cavity. The storage holder is sleeved on the outside of the storage device, and a flow control hole is provided on the side wall of the storage holder. One of the storage holder and the storage device is fixedly connected to the housing, while the other can rotate around the central axis. The immersion hole is connected to the diversion cavity through the flow control hole. When the storage holder and the storage device rotate relative to each other, the immersion hole and the flow control hole can be partially misaligned.

[0011] Furthermore, the diversion cavity includes a first diversion cavity and a second diversion cavity that are separated from each other. The first diversion cavity is connected to the impregnation hole, and the second diversion cavity is connected to the second water spray hole group. The diversion seat is provided with a first flow channel and a second flow channel. One end of the first flow channel is connected to the first diversion cavity, and the other end is connected to the water inlet in a first state. One end of the second flow channel is connected to the second diversion cavity, and the other end is connected to the water inlet in a second state.

[0012] Furthermore, both the first and second diversion cavities are annular cavities arranged around the central axis, and the first diversion cavity is located inside the second diversion cavity.

[0013] Furthermore, the diversion seat includes a base portion and several annular first enclosure portions. The base portion is rotatably connected to the housing. The first enclosure portions extend along the central axis and are disposed on the front side of the base portion. The first enclosure portions are nested inside and outside each other and spaced apart. Several annular second enclosure portions are formed on the front cover extending along the central axis. The second enclosure portions and the first enclosure portions press against each other one-to-one, and the two together form the diversion cavity.

[0014] Furthermore, the diverter seat and / or the front cover are provided with several alignment steps, and the diverter seat and the front cover are pressed together by the alignment steps; a sealing gasket is provided at both the water inlet and the alignment steps.

[0015] Furthermore, the flow divider seat is provided with an arc-shaped adjustment hole, and a fastener is inserted into the arc-shaped adjustment hole. The fastener is used to connect the flow divider seat and the housing, and the fastener can move relative to the flow divider seat within the arc-shaped adjustment hole as the flow divider seat rotates. The nozzle is also equipped with a positioning structure, which includes a positioning spring, a positioning ball, and at least two positioning holes. The positioning holes are spaced apart on the rear side of the flow divider. The positioning spring is arranged along the central axis, with one end abutting against the housing and the other end pressing the positioning ball against the positioning hole. When the flow divider is switched to different states, the positioning ball moves with the positioning spring to different positioning holes.

[0016] Furthermore, the diverter seat can be rotated to switch to a third state, in which the diverter chamber and the inlet are isolated from each other, and the diverter seat blocks the inlet.

[0017] This utility model has the following beneficial effects: This shower head has a built-in reservoir for storing functional materials and a diverter seat for guiding water flow and switching functions. By rotating the diverter seat, the shower head can be switched to a first state and a second state. In the first state, the water flow from the inlet passes through the diverter chamber, the soaking hole, the storage chamber, and the outlet in sequence, fully contacting the functional materials before being sprayed out through the first spray nozzle group to achieve additional functions. In the second state, the water flow from the inlet can be sprayed directly through the diverter chamber and the second spray nozzle group to achieve the basic clean water shower function. The switching between the basic function and the additional function is convenient and smooth. Attached Figure Description

Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 1-4As shown, this utility model provides a multifunctional shower head, which includes a handle 100 and a spray head 200 connected to each other. The handle 100 has a hollow inner cavity 110, and the spray head 200 includes a housing 210, a reservoir 220, a diverter seat 230, and a front cover 240. The housing 210 has an assembly cavity 211 with a front opening, and the assembly cavity 211 has a water inlet 212 that communicates with the inner cavity 110 of the handle 100. The reservoir 220 is disposed in the assembly cavity 211 and avoids the water inlet 212. The reservoir 220 has a storage chamber 221 for storing functional materials such as medicine packets and essential oil packets, and the reservoir 220 has a water outlet 2221 and a soaking hole 2231 that communicate with the storage chamber 221. The flow divider 230 is rotatably mounted in the assembly cavity 211 around the central axis of the nozzle 200, and the flow divider 230 separates the flow divider cavity 233 between the housing 210 and the storage container 220. The front cover 240 is located on the front side of the housing 210 and closes the assembly cavity 211, and cooperates with the housing 210 to encapsulate the storage container 220 and the flow divider 230. The front cover 240 has a first water spray hole group 241 and a second water spray hole group 242. The first water spray hole group 241 and the second water spray hole group 242 are both composed of multiple densely arranged small holes, wherein the first water spray hole group 241 is connected to the water outlet 2221, and the second water spray hole group 242 is connected to the flow divider cavity 233.

[0034] The diverter seat 230 can be rotated to switch between different states. When part of the diverter seat 230 is exposed on the outside of the nozzle 200, the switching operation can be achieved by directly rotating the diverter seat 230. When the diverter seat 230 is hidden, it can be indirectly driven by other components. In this embodiment, the front cover 240 and the diverter seat 230 are fastened together by common structures such as hook structures and threaded structures, and the two are relatively fixed. Rotating the front cover 240 can drive the diverter seat 230 to rotate, thereby switching states. The nozzle 200 is aesthetically pleasing overall.

[0035] The switchable states include at least a first state and a second state. For example... Figure 12 As shown, in the first state, the diversion chamber 233 connects the water inlet 212 and the immersion hole 2231, guiding water flow through the immersion hole 2231 into the storage chamber 221 to contact the functional material, and then spraying it out of the front cover 240 through the water outlet 2221 and the first spray hole group 241, realizing additional functions such as medicated baths. In the second state, as... Figure 13 As shown, the diversion chamber 233 connects to the water inlet 212 but isolates the impregnation hole 2231, allowing water to be directly guided from the water inlet 212 to the second spray hole group 242 for spraying, thus achieving a basic clean water shower function. The transition between the two states is convenient and smooth, without affecting the continuity of bathing, resulting in a better bathing experience.

[0036] In addition, the aforementioned storage chamber 221 is also provided with a loading port 2211, which is located on the rear side of the storage chamber 221 and is used for loading and unloading materials. Correspondingly, the nozzle 200 is also provided with a rear cover 250, which is detachably connected to the rear side of the housing 210 to open and close the loading port 2211. The detachable connection method can be a snap-fit ​​connection, a direct plug-in connection, a threaded connection, etc. Through the detachable rear cover 250 and the loading port 2211, functional materials can be quickly replaced, which is especially suitable for materials with a short service life, such as medicine packets. On this basis, a sealing gasket 280 can be provided between the rear cover 250 and the housing 210 or between the rear cover 250 and the storage container 220 to improve the sealing performance of the storage chamber 221 while achieving detachability.

[0037] Furthermore, after the material is removed, the back cover 250 can be installed directly and the diverter seat 230 can be rotated to switch it to the first state. This can also guide clean water to flow through the empty storage chamber 211, quickly cleaning the storage chamber 211 and preventing residual material inside the shower head and the deterioration of the material caused by the residue.

[0038] More specifically, such as Figure 5 As shown, the storage tank 220 includes an inner sleeve 222 and an outer sleeve 223 nested together. Both the inner sleeve 222 and the outer sleeve 223 are arranged along the central axis of the spray head 200. The inner sleeve 222 is provided with a water outlet 2221, and the interior of the inner sleeve 222 forms a storage cavity 221. The outer sleeve 223 is provided with a immersion hole 2231. A flow guiding layer 224 is formed between the inner sleeve 222 and the outer sleeve 223. The flow guiding layer 224 is connected to the storage cavity 221 on the side away from the water outlet 2221, which can extend the water flow path and make it more fully contact the functional materials, thus giving fuller play to the additional functions of the shower head.

[0039] In this embodiment, the water outlets 2221 are evenly distributed at the front end of the inner sleeve 222, and the flow guide jacket 224 communicates with the storage chamber 221 at the rear end of the inner sleeve 222. A cylindrical storage holder 213 is also provided inside the assembly cavity 211 of the housing 210. This storage holder 213 is sleeved on the outside of the storage container 220, and a flow control hole 2131 is provided on the side wall of the storage holder 213. One of the storage holder 213 and the storage container 220 is fixedly connected to the housing 210, while the other can rotate around the central axis of the nozzle 200. The aforementioned impregnation hole 2231 is connected to the diversion chamber 233 through the flow control hole 2131. When the storage holder 213 and the storage container 220 rotate relative to each other, the immersion hole 2231 and the flow control hole 2131 can be partially offset. By adjusting the degree of offset between the immersion hole 2231 and the flow control hole 2131, the water flow can be adjusted accordingly to meet different rinsing needs.

[0040] Preferably, the storage holder 213 is integrally formed with the housing 210, and the rotation adjustment of the storage device 220 can be achieved by opening and closing the rear cover 250. Under the premise of meeting the adjustment requirements, the structure of the nozzle 200 can be made more concise and compact.

[0041] like Figure 6 , 7 As shown, the flow divider 233 includes a first flow divider 2331 and a second flow divider 2332 separated from each other. The first flow divider 2331 is connected to the impregnation hole 2231, and the second flow divider 2332 is connected to the second water spray hole group 242. Correspondingly, the flow divider seat 230 is provided with a first flow channel 234 and a second flow channel 235 for connecting the flow divider 233 and the water inlet 212. Wherein, as... Figure 8 As shown, one end of the first flow channel 234 is connected to at least the first diversion cavity 2331, and the other end is connected to the inlet 212 in the first state, which can guide water flow into the first diversion cavity 2331 and the immersion hole 2231 to contact the material, thereby realizing additional functions. Figure 9 As shown, one end of the second flow channel 235 is connected to the second diversion cavity 2332, and the other end is connected to the inlet 212 in the second state, which can guide the water flow to avoid the material and realize the basic function.

[0042] A sealing gasket 280 can be added at the inlet 212 of the first flow channel 234 and the second flow channel 235 to ensure the sealing during state switching and avoid mutual interference between different states. The first diversion cavity 2331 and the second diversion cavity 2332 are preferably annular cavities arranged around the central axis, and the first diversion cavity 2331 is located inside the second diversion cavity 2332 so as to connect with the impregnation hole 2231.

[0043] The first flow channel 234 and the second flow channel 235 are arranged in parallel and spaced apart. When neither of them is connected to the inlet 212, the diverter seat 230 switches to the third state. In the third state, the diverter chamber 233 and the inlet 212 are isolated from each other, and the rear side of the diverter seat 230 blocks the inlet 212, thus achieving a water-stopping function.

[0044] The diverter seat 230 mainly includes a base portion 231 and several annular first enclosure portions 232. The base portion 231 is rotatably connected to the housing 210. The first enclosure portions 232 extend along the central axis and are disposed on the front side of the base portion 231. The first enclosure portions 232 are nested and spaced apart from each other. Correspondingly, as... Figure 10 , 11As shown, several annular second enclosure portions 243 extend along the central axis on the front cover 240. The second enclosure portions 243 and the first enclosure portions 232 press against each other one-to-one, and the two enclose each other to form a diversion cavity 233. In this diversion cavity 233, the first diversion cavity 2331 is formed by the first enclosure portion 232 and the second enclosure portion 243 in conjunction with the side wall of the storage card seat 213, and the second diversion cavity 2332 is formed by the first enclosure portion 232 and the second enclosure portion 243 directly enclosing each other.

[0045] To ensure a tight fit between the flow divider 230 and the front cover 240, several alignment steps 244 are provided on the flow divider 230 and / or the front cover 240, and the flow divider 230 and the front cover 240 are mutually pressed together by the alignment steps 244. A sealing gasket 280 is provided at each alignment step 244 to improve the sealing performance of the flow divider cavity 233.

[0046] The distributor seat 230 and the housing are detachably connected by a thread. Specifically, an arc-shaped adjustment hole 2311 is provided on the base 231 of the distributor seat 230, and a bolt fastener 270 is inserted into the arc-shaped adjustment hole 2311. The end of the fastener 270 is locked into the threaded post 214 in the housing 210, which can securely mount the distributor seat 230 on the housing 210 and, together with the arc-shaped adjustment hole 2311, enable the rotation switching of the distributor seat 230. When the distributor seat 230 rotates, the fastener 270 can move relative to the distributor seat 230 within the arc-shaped adjustment hole 2311, thus limiting the rotation angle of the distributor seat 230.

[0047] In addition, the nozzle 200 is internally equipped with a positioning structure 260, which includes a positioning spring 261, a positioning ball 262, and at least two positioning holes 263. The positioning holes 263 are spaced apart on the rear side of the flow divider 230. The positioning spring 261 is positioned along the central axis, with one end mounted in the spring mounting seat 215 of the housing 210 to abut against the housing 210, and the other end pressing the positioning ball 262 against the positioning hole 263. The positioning spring 261 is always kept compressed. When the flow divider 230 switches to different states, the positioning ball 262 can move with the positioning spring 261 to different positioning holes 263, and presses the positioning hole 263 under the action of the positioning spring 261, thus achieving gear positioning.

[0048] In this embodiment, three positioning holes 263 are spaced apart to correspond to the first, second, and third states of the diverter seat 230, respectively. The end of the positioning tumbler 262 is hemispherical, and the positioning hole 263 is preferably a semi-circular hole. The hemispherical surface allows the diverter seat 230 to rotate and reposition more smoothly. In addition, a limiting protrusion 2312 is provided next to the positioning hole 263 to block the positioning tumbler 262 and prevent it from shifting excessively.

[0049] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims are within the scope of protection of the present invention.
