Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, and in particular to a water outlet device. Background Technology

[0002] Showering, as an integral part of life, plays a vital role in personal relaxation and hygiene. The shower process requires the use of shower gel and other consumables to remove sweat, oil, dirt, and metabolic waste from the skin's surface, while also using fragrance to regulate mood. However, shower gel is typically applied manually or with the aid of tools like bath sponges, which is inconvenient.

[0003] Therefore, a shower head is proposed in the related technology, which has a venturi tube and a liquid storage box inside the shower head shell. When water flows through the venturi tube, it can generate negative pressure, which squeezes the shower liquid from the liquid storage box into the water channel, realizing the mixing of shower liquid and water. However, after the shower liquid and water are mixed, they are directly discharged through the water outlet of the shower head, which does not easily produce foam. The cleaning effect of the shower liquid is poor, and the shower liquid is not fully foamed, so it is easy to leave residue on the body. It is necessary to scrub vigorously to avoid the pore blockage caused by the shower liquid residue. Utility Model Content

[0004] The purpose of this invention is to provide a water outlet device to solve the problem of poor foaming effect after the shower gel and water are mixed.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A water outlet device includes a liquid storage box, a venturi tube, a first water outlet cavity, and a first dividing member. The venturi tube includes a first inlet, a second inlet, and an outlet. The first inlet is used to connect to an external water supply pipeline, and the second inlet is connected to the liquid storage box. The first water outlet cavity is provided with an air inlet and a first water outlet, which are connected to the outside. The first water outlet cavity is also provided with a first water inlet, which is connected to the outlet. The first dividing member is disposed in the first water outlet cavity and located between the first water outlet and the first water inlet. The first dividing member is provided with multiple dividing holes, and the area of ​​the dividing holes is larger than the minimum diameter of the venturi tube.

[0007] In one embodiment, the first dividing member is configured as a groove-shaped structure, with the groove opening of the first dividing member facing away from the first water outlet, and a plurality of dividing holes are arranged circumferentially on the side wall of the first dividing member.

[0008] In one embodiment, the bottom wall of the groove of the first dividing member is provided with a protrusion, and the length of the protrusion gradually increases from one end near the groove opening of the first dividing member to the other end.

[0009] In one embodiment, the dividing hole is configured as a rectangular hole.

[0010] In one embodiment, the first segment is closer to the first outlet than the first inlet.

[0011] In one embodiment, the water outlet device further includes a second dividing member, which is disposed between the first dividing member and the first water outlet, and the second dividing member is a filter screen.

[0012] In one embodiment, the water outlet device further includes a second water outlet chamber and a switching valve. The second water outlet chamber has a second water outlet that connects to the outside and a second water inlet for connecting to the external water supply pipeline. The switching valve selectively connects to the first liquid inlet or the second water inlet.

[0013] In one embodiment, the water outlet device further includes a water outlet body, and the liquid storage box, the first water outlet cavity, the venturi tube, and the second water outlet cavity are all integrated on the water outlet body.

[0014] In one embodiment, the venturi tube is disposed inside the water outlet body.

[0015] In one embodiment, the water outlet device further includes a handle, which is disposed on one side of the water outlet body.

[0016] In one embodiment, a gravity-assisted liquid-absorbing ball is movably disposed inside the liquid storage box, and the gravity-assisted liquid-absorbing ball is connected to the Venturi tube.

[0017] The beneficial effects of this utility model are as follows: The above-mentioned water outlet device has a first dividing member installed downstream of the Venturi tube. When the water flows through the Venturi tube, according to the Venturi principle, the water flow velocity is the fastest at the throat of the Venturi tube, generating negative pressure. The negative pressure forces the consumables from the storage box into the Venturi tube to mix with the water flow. As the water flows downstream to the first water outlet cavity, the water flow is divided into multiple water columns under the action of the dividing hole of the first dividing member. The water flow also generates a certain negative pressure after passing through the first dividing member, which draws air into the first water outlet cavity through the air inlet, promoting the mixing and foaming of the consumables and the water flow. This makes the water flowing out of the first outlet milky white and the foam dense. On the one hand, it eliminates the need to use external materials to foam during the bathing process. On the other hand, the fully mixed and foamed consumables can be easily removed from the skin by rinsing with clean water, reducing the possibility of consumables remaining on the skin. It is important to emphasize that the area of ​​the dividing hole is larger than the minimum diameter of the venturi tube. This can prevent flow restriction at the dividing hole and ensure that the flow velocity of the water at the throat of the venturi tube is greater than that at the dividing hole, thus preventing the venturi tube from failing to pick up consumables.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0031] refer to Figures 1-7As shown in the figure, an embodiment of this utility model proposes a water dispensing device, including a Venturi tube 7, a liquid storage box 2, a first water dispensing chamber 3, and a first dividing member 30. The liquid storage box 2 contains a liquid consumable with a cleaning effect, which is not limited to shower gel or hand soap, and can mix with water to form foam. To facilitate the addition of consumables to the liquid storage box 2, the liquid storage box 2 includes a box body 21 and a box cover 22. The box cover 22 is detachably connected to the box body 21 by a method not limited to snap-fit ​​or bolt connection. When adding consumables, simply remove the box cover 22 to replenish the consumables in the box body 21. The Venturi tube 7 includes a first inlet 71, a second inlet 72, and an outlet 73. The first inlet 71 is used to connect to an external water supply pipeline. The second inlet 72 is connected to the storage box 2. The outlet 73 is connected to the first water inlet (not shown in the figure) provided on the first water outlet cavity 3. The first water outlet cavity 3 is provided with an air inlet 323 and a first water outlet 321 that connect to the outside. Multiple first water outlets 321 can be provided. The first dividing member 30 is provided in the first water outlet cavity 3 and is located between the first water inlet and the first water outlet 321. The air inlet 323 is located between the first dividing member 30 and the first water outlet 321. Multiple dividing holes 302 are provided on the first dividing member 30. The area of ​​any dividing hole 302 is greater than the minimum diameter of the Venturi tube 7, that is, greater than the cross-sectional area of ​​the narrowest part (throat) of the Venturi tube 7.

[0032] The aforementioned water outlet device has a first dividing element 30 installed in the first water outlet cavity 3 at the downstream end of the Venturi tube 7. When the water flows through the Venturi tube 7, according to the Venturi principle, the water flow velocity is fastest at the throat of the Venturi tube 7, generating negative pressure. The negative pressure forces the consumables from the liquid storage box 2 into the Venturi tube 7 to mix with the water flow. As the water flows downstream to the first water outlet cavity 3, under the action of the dividing hole 302 of the first dividing element 30, the water flow is divided into multiple water columns, which can also generate a certain negative pressure, drawing air into the first water outlet cavity 3 from the air inlet 323, promoting the mixing and foaming of the consumables and the water flow. This results in the water spraying out from the first water outlet 321 being milky white and having dense foam. On the one hand, it eliminates the need to use external materials to foam during the bathing process. On the other hand, the fully mixed and foamed consumables can be easily removed from the skin by rinsing with clean water, reducing the possibility of consumables remaining on the skin.

[0033] It is important to emphasize that the area of ​​any dividing hole 302 is larger than the minimum diameter of the venturi tube 7. This can prevent flow restriction at the dividing hole 302, ensuring that the flow velocity of water at the minimum diameter of the venturi tube 7 is greater than the flow velocity at the dividing hole 302. This prevents the venturi tube 7 from failing to pick up consumables (if the area of ​​the dividing hole 302 is too small, the venturi tube 7 will not have enough space to expand, which will cause the water pressure to be unable to be released, resulting in static pressure, increased water friction, energy loss, and reduced flow velocity, making it impossible for the venturi tube 7 to pick up consumables).

[0034] Specifically, refer to Figure 5 and Figure 6 As shown, the first dividing member 30 is configured as a groove-shaped structure, with its groove opening facing away from the first water outlet 321. Water flows into the first dividing member 30 through the groove opening and then flows out of the first dividing member 30 through the dividing holes 302. Multiple dividing holes 302 are arranged circumferentially on the side wall of the first dividing member 30. More specifically, the dividing holes 302 are rectangular holes. With the same area, the rectangular holes divide the water flow into larger outer surfaces, allowing for more sufficient contact with air, resulting in denser bubbles and a better foaming effect.

[0035] In addition, the bottom wall of the first dividing member 30 is provided with a protrusion 301. The protrusion 301 gradually increases in length from one end near the opening of the first dividing member 30 to the other end, so as to divert the water flow and make the water flow evenly to each dividing hole 302.

[0036] To reduce the possibility of foam dissolution formed by the first dividing member 30, the first dividing member 30 is closer to the first outlet 321 than the first inlet. This results in a smaller distance between the first dividing member 30 and the first outlet 321, allowing the foam formed by the first dividing member 30 to flow out quickly through the first outlet 321. For example, the first dividing member 30 is in contact with the first outlet 321.

[0037] In one embodiment, the water outlet device further includes a second dividing member 40, which is disposed between the first dividing member 30 and the first water outlet 321 to further divide the water flow, thereby forming a denser foam. To reduce the interference of the second dividing member 40 with the air intake of the first dividing member 30 and the liquid intake of the Venturi tube 7, the second dividing member 40 is a filter screen. Specifically, the second dividing member 40 uses a filter screen with a mesh size between 30 and 50 mesh. Filter screens within this mesh size range have a high pore density and a low restriction effect on the water flow.

[0038] refer to Figures 2-4As shown, based on the diverse usage needs of users, the water outlet device also includes a second water outlet chamber 4 and a switching valve 6. The second water outlet chamber 4 has a second water outlet 421 connected to the outside and a second water inlet (not shown in the figure) for connecting to the external water supply pipeline. The specific form of the switching valve 6 is not limited here. It can selectively connect the external water supply pipeline to the first liquid inlet 71 of the Venturi tube 7 or the external water supply pipeline to the second water inlet of the second water outlet chamber 4. When the external water inlet pipe is connected to the first inlet 71 of the Venturi tube 7, water flows through the Venturi tube 7. Under negative pressure, the consumables are squeezed into the Venturi tube 7 and mixed with the water. The water mixed with the consumables flows out from the first outlet 321. At this time, the water outlet provides the user with foam formed by the mixture of consumables and water. When the external water inlet pipe is connected to the second inlet, the water flows through the second outlet cavity 4 and then directly to the second outlet 421. At this time, the water outlet provides the user with clean water to facilitate rinsing off the foam formed by the consumables adhering to the skin.

[0039] To improve the integration of the water outlet device, the device also includes a water outlet body 1, a liquid storage box 2, a first water outlet cavity 3, a venturi tube 7, and a second water outlet cavity 4, all integrated on the water outlet body 1. In one embodiment, the venturi tube 7 is disposed inside the water outlet body 1 to reduce the volume of the water outlet device, and a first connection channel 11 connecting the venturi tube 7 to an external water supply pipeline is provided inside the water outlet body 1.

[0040] Specifically, in order to reduce the assembly difficulty of the Venturi tube 7, an installation channel 12 is also provided in the water outlet body 1 to connect the first connecting channel 11. The installation channel 12 is connected to the liquid storage box 2 through the connecting hole 14. An annular abutment part 15 is provided on the inner wall of one end of the installation channel 12 that connects to the first connecting channel 11. One end of the Venturi tube 7 with the first liquid inlet 71 abuts against the abutment part 15. The other end of the Venturi tube 7 with the liquid outlet 73 abuts against the limiting sleeve 20 inserted and fixed in the installation channel 12. The limiting sleeve 20 connects the Venturi tube 7 and the first water outlet cavity 3.

[0041] Meanwhile, the liquid storage box 2 and the second water outlet chamber 4 are respectively located on opposite sides of the water outlet body 1, and the first water outlet chamber 3 is located in the avoidance hole set in the center of the second water outlet chamber 4, so as to provide users with a wider range of clean water flow, thereby improving cleaning efficiency. More specifically, the second water outlet cavity 4 includes a second water outlet cap 42 and a second water inlet cap 41. The second water inlet cap 41 is fixedly connected to the water outlet body 1. The second water outlet cap 42 is disposed on the side of the second water inlet cap 41 facing away from the liquid storage box 2 and cooperates with the second water inlet cap 41 to form the second water outlet cavity 4. The second water inlet is disposed on the second water inlet cap 41, and the second water outlet 421 is disposed on the second water outlet cap 42. The first water outlet cavity 3 includes a first water inlet cap 31 and a first water outlet cap 32. The first water inlet cap 31 is fixed to the water outlet body 1, for example, the first water inlet cap 31 is integrally formed with the water outlet body 1. The first water outlet cap 32 is detachably connected to the second water outlet cap 42 and together with the first water inlet cap 31 forms the first water outlet cavity 3 that accommodates the first dividing member 30 and the second dividing member 40. The first water outlet 321 and the air inlet 323 are disposed on the first water outlet cap 32, and the first water inlet is disposed on the first water inlet cap 31.

[0042] refer to Figure 3 As shown, the water outlet device also includes an installation sleeve 10. The outer wall of the installation sleeve 10 has external threads, while the inner wall of the clearance hole has internal threads. The installation sleeve 10 is threadedly connected to the second water outlet cover 42. Simultaneously, a limiting step is provided inside the installation sleeve 10. The first water outlet cover 32 is inserted into the installation sleeve 10 and abuts against the limiting step. The limiting step provides unidirectional limiting for the first water outlet cover 32, preventing it from detaching from the installation sleeve 10 in a direction away from the water outlet body 1. An annular groove 322 is provided on the inner wall of the first water outlet cover 32, and the first dividing member 30 is engaged within the groove 322.

[0043] In order to allow water to flow better through the second segment 40, the first water outlet cover 32 is provided with an annular boss 324 on the side facing the second segment 40, and the first segment 30 is provided with a protruding limiting part 303 on the side facing the second segment 40. The opposite sides of the second segment 40 abut against the limiting part 303 and the boss 324 respectively, so that there are gaps between the second segment 40, the first segment 30 and the first water outlet cover 32.

[0044] It is worth emphasizing that in order for air to enter the first water outlet chamber 3 smoothly through the air inlet 323, there is also a gap between the first water outlet cover 32 and the mounting sleeve 10.

[0045] During normal showering, some users have the habit of holding the water outlet device to flexibly adjust its angle. In addition, the water outlet device also includes a handle 5, which is located on one side of the water outlet body 1 for easy gripping. A switching valve 6 is located on the handle 5. The handle 5 is provided with a first water inlet channel 51 that connects to the external water supply pipe and the first connecting channel 11, and a second water inlet channel 52 that connects to the external water supply pipe and the second water outlet chamber. By adjusting the switching valve 6, the first water inlet channel 51 and the second water inlet channel 52 can be selectively connected to the external water supply pipe.

[0046] Furthermore, a gravity-assisted suction ball 8 is movably installed inside the liquid storage box 2. The gravity-assisted suction ball 8 is connected to the Venturi tube 7 and, under its own gravity, remains below the consumable interface within the liquid storage box 2, thus ensuring that consumables are drawn in and squeezed into the Venturi tube 7. Specifically, the gravity-assisted suction ball 8 is installed inside the liquid storage box 2 via a suction tube 9, which includes a fixed part 91 and a movable part 92. The fixed part 91 is fixedly installed inside the liquid storage box 2, and the movable part 92 is made of flexible material, with one end connected to the fixed part 91 and the other end connected to the gravity-assisted suction ball 8. More specifically, the movable part 92 is inclined upwards from the end connected to the gravity-assisted suction ball 8 towards the end connected to the fixed part 91. Therefore, when no water flow is flowing into the Venturi tube 7, consumables in the liquid storage box 2 are less likely to enter the Venturi tube 7, reducing the possibility of consumables being damaged when the shower head is not in use.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
