Description

Technical Field

[0001] The utility model relates to the field of bathrooms, in particular to a water outlet device and a bubbler. Background Art

[0002] In order to enrich the water splash of the faucet, more and more users install water outlet devices at the water outlet of the faucet. This type of water outlet device can form different forms of water splashes such as shower water, bubble water, and single water column. Among them, bubble water relies on the air inlet channel opened on the side wall of the water outlet device. When the water flows, it can drive the gas from the air inlet channel into the cavity of the water outlet device and mix with the water flow to form. For example, in the Chinese patent document with publication number CN218924335U, an air inlet channel is set on the water divider, and the air outlet of the air inlet channel is connected to the water mixing chamber. When the water flows in, the gas will be brought into the water mixing chamber due to the air pressure difference. In the above patent, the air outlet of the air inlet channel is set around the side wall of the water mixing chamber, which is prone to insufficient air intake pressure, resulting in insufficient air intake, and then unable to mix enough air into the bubble water, and finally resulting in low air-water mixing ratio, uneven air-water mixing, poor water-saving effect, and other problems in the bubble water formed, and the user experience is not good.

[0080] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0081] Please refer to Figure 1-Figure 20A bubbler includes a shell 1 and a water outlet device 2, wherein the shell 1 is sleeved outside the water outlet device 2 and forms an air suction gap with the circumferential side wall of the water outlet device 2. The water outlet device 2 includes a water inlet component 21 and a water outlet panel 22; the water outlet panel 22 is arranged in the water outlet 211 of the water inlet component 21; the water inlet component 21 has a water inlet channel 212, an air inlet channel 213 and a water mixing chamber 214; the air inlet channel 213 has a first air outlet 215 and a second air outlet 216; the first air outlet 215 is located on the side wall of the water inlet channel 212, and the first air outlet 215 is connected to the water inlet channel 212, the second air outlet 216 is connected to the water inlet channel 212 or to the water mixing chamber 214, and the water inlet channel 212 is connected to the water mixing chamber 214; the water outlet panel 22 has a water flow dividing component 221 coaxially arranged with the water inlet component 21, and the water flow dividing component 221 includes at least one layer of a screen with a mesh number of 200 to 1000. Among them, the shell 1 can be a shell with an external thread structure, or a shell with an internal thread structure.

[0082] It can be understood that in order to allow more gas to be sucked into the water outlet device 2 and mixed with the water flow, it is necessary to allow the water flow to inhale a large amount of air by generating negative pressure when flowing through the water inlet channel 212. The first air outlet 215 and the second air outlet 216 provided in this scheme can allow air to be sucked in from different positions and more passages, so that the water flow and the gas have sufficient time to be fully mixed in the process of entering the mixing water chamber 214, and finally bubble water containing sufficient bubbles and basically mixed evenly with the water flow is formed in the mixing water chamber 214; further, the setting of the water flow dividing component 221 prevents the water flow from passing through easily, and the water flow in the mixing water chamber 214 is filled, so that the water pressure inside the mixing water chamber 214 and the water inlet channel 212 increases, allowing the water flow to obtain greater energy to pass through the water flow dividing component 221, so that the large bubbles in the water flow can be better cut into micro bubbles, and the micro bubbles can be more evenly mixed in the water flow and remain longer. The utility model adopts the method of adding a water flow dividing component 221 to increase the water pressure in the water mixing chamber 214, and adjusts the position of the air inlet channel 213 and sets the first air outlet 215 and the second air outlet 216 to increase the air intake volume. In conjunction with the division of the water flow dividing component 221, the bubble water discharged to the outside is more evenly mixed with sufficient air that is cut into a very small volume, thereby improving the water outlet effect of the bubble water, making the bubble water outlet softer, and enhancing the user's water experience.

[0083] In some embodiments, the water inlet assembly 21 includes an upper body 217, a lower body 218 and an inner shell 219; the upper body 217 and the lower body 218 are sequentially arranged in the inner shell 219 along the water outlet direction; the outer wall of the lower body 218 and the side of the upper body 217 facing the lower body 218 form an air inlet channel 213. The air inlet channel 213 is formed between the upper body 217 and the lower body 218 to create conditions for the water inlet channel 212 to inhale air, ensuring that air can be continuously inhaled during the water outlet process.

[0084] In some embodiments, the upper body 217 and the lower body 218 are at least partially pressed against each other to form a first air outlet 215, and the first air outlet 215 is located between the upper body 217 and the lower body 218, and this position is also located in the water inlet channel 212, so that water can inhale some air when it enters the water inlet channel 212 and is not discharged from the water inlet channel 212.

[0085] In some embodiments, the second air outlet 216 is located in the outlet of the water inlet channel 212, so that the first air outlet 215 and the second air outlet 216 are staggered in the axial direction and / or in the circumferential direction, and are used to inhale air at different positions of the water inlet channel 212, so that the water flow mixes with the air and enters the mixing water chamber 214, thereby increasing the air intake.

[0086] In some embodiments, the lower body 218 has a recessed portion 2181 on one side close to the upper body 217, and the recessed portion 2181 is located at a position of the air inlet channel 213 close to the water inlet channel 212; the first air outlet 215 and the second air outlet 216 are respectively connected to the recessed portion 2181. The recessed portion 2181 can be used as an airflow storage space for the airflow input into the air inlet channel, and the airflow is stored in this larger space and then output to the first air outlet 215 and the second air outlet 216, providing sufficient air intake space for the first air outlet 215 and the second air outlet 216, so that when the water flow inhales, sufficient and continuous air can be inhaled into the first air outlet 215 and the second air outlet 216 and fully mixed with the water flow, thereby increasing the gas content in the bubble water.

[0087] In some embodiments, the second air outlet 216 is opened on the lower body 218 and is connected to the water mixing chamber 214. Specifically, the opening position of the second air outlet 216 is located outside the water inlet channel 212. The second air outlet 216 is arranged in the water mixing chamber 214, which can enable air to be sucked into the water mixing chamber 214 and mixed with the water flow, thereby increasing the air intake.

[0088] In some embodiments, the inner shell 219 is provided with an air intake hole 2191 connected to the air intake channel 213, and the outer wall of the inner shell 219 is provided with an air intake groove 111 for connecting the air intake hole 2191 with the external space. The air intake hole 2191 and the air intake channel 11 are provided to provide sufficient air for the air intake channel 213 to ensure the smoothness of air intake.

[0089] In some embodiments, more than two first air outlets 215 and second air outlets 216 are provided, and all first air outlets 215 and all second air outlets 216 are evenly distributed around the axis of the upper body 217. Providing multiple first air outlets 215 and second air outlets 216 can increase the air intake, and evenly distributed settings can increase the uniformity of mixing air and water flow.

[0090] In some embodiments, the water inlet assembly 21 further includes a water saving member 23, which is connected to the water inlet assembly 21 and located at the water inlet end of the water inlet channel 212. The water saving member 23 is provided to control water flow and limit or maintain a constant flow rate.

[0091] In some embodiments, a sealing ring 24 is provided between the lower body 218 and the inner shell 219. The sealing ring 24 is provided to ensure that air enters the air inlet channel 213 from the air inlet hole 2191, prevents the air flow from flowing to other positions, and ensures sufficient air intake pressure.

[0092] In some embodiments, the first air outlet 215, the second air outlet 216 and the air inlet of the air inlet channel 213 are arranged in sequence along the water outlet direction. Taking the water outlet device 2 in the lower water outlet state as an example, the first air outlet 215 is higher than the second air outlet 216, and the second air outlet 216 is higher than the air inlet of the air inlet channel 213.

[0093] In some embodiments, the water flow segmentation component 221 includes at least two layers of screens 2211 stacked in sequence, wherein the mesh number of the screen 2211 is 200 mesh to 1000 mesh, and optionally, the mesh number of the screen 2211 is 200 mesh, 400 mesh, 600 mesh, 800 mesh or 1000 mesh. The higher the mesh number, the greater the water flow discharge resistance and the greater the pressure of the water body in the mixing water chamber 214. When the high-pressure water flow passes through the screen 2211, the bubbles will be cut finer, and more gas can remain in the water flow for a longer time. Among them, the number of screens 2211 can be three layers, four layers or more, and the screens 211 of different layers can be set to have the same mesh number or different mesh numbers; when the number of layers of the screen 2211 is more, the corresponding pressure in the mixing water chamber 214 is also greater.

[0094] In some embodiments, the water outlet panel 22 is reversibly connected to the water inlet assembly 21, and the water outlet panel 22 has a first water outlet 222 and a second water outlet 223; the cross-sectional area of ​​the first water outlet 222 is smaller than the cross-sectional area of ​​the second water outlet 223. The first water outlet 222 and the second water outlet 223 are provided to facilitate the reverse flushing of the screen 2211 and the drainage holes in the water outlet panel 22, thereby playing a role in cleaning; on the other hand, the water outlet panel 22 can be applied to different usage scenarios. Specifically, when the first water outlet 222 is used as a water flow discharge port, due to its small cross-sectional area, the discharged water column is thinner, so that the water column is concentrated, the water flow pressure is increased, and the jet height is also high, which can be applied to the scene of upper water discharge, such as daily gargling, washing face, etc.; when the second water outlet 223 is used as a water flow discharge port, due to the increased cross-sectional area, the discharged water column is thicker, the water flow pressure is reduced, and the jet height cannot meet the scene of upper water discharge, it is applied to the scene of lower water discharge. In this solution, in different usage scenarios, the water outlet device can discharge water at a suitable water pressure, thereby improving the user's water use experience.

[0095] In some embodiments, the water outlet panel 22 further includes a rectifying bracket 224, a panel body 225 and a cover 226; the rectifying bracket 224 is coaxially arranged with the panel body 225 and embedded in the panel body 225, and the cover 226 is covered on the side of the rectifying bracket 224 away from the panel body 225; in the axial direction of the panel body 225, at least one water flow dividing component 221 is sandwiched between the rectifying bracket 224 and the cover 226 and between the rectifying bracket 224 and the panel body 225. Among them, a water grid for water to flow through is also provided on the rectifying bracket 224.

[0096] In some embodiments, in the axial direction of the panel body 225, water inlet grilles 227 are respectively provided on the side of the cover body 226 facing the water flow dividing component 221 and the side of the panel body 225 facing the water flow dividing component 221. Due to the setting of the water inlet grille 227, a water passage is formed between the cover body 226 and the water flow dividing component 221 and between the panel body 225 and the water flow dividing component 221, so that the water flow is more conducive to the gas passing through the water inlet grille 227 into the mixing water chamber 214 to mix with the water flow.

[0097] In some embodiments, there is only one water inlet channel 212, and the water inlet channel 212 is located at the axis of the water inlet assembly 21. Providing only one water inlet channel 212 can ensure the concentration of water flow, thereby reducing the loss of water pressure, and generating a sufficiently large negative pressure to attract air when the water flows through different water inlet sections. Although providing more than two water inlet channels 212 of the same structure can also generate negative pressure, the actual suction effect is not as good as the suction effect of providing only one water inlet channel 212.

[0098] In some embodiments, the water inlet channel 212 includes a first water inlet section 2121 and a second water inlet section 2122 sequentially arranged along the water inlet direction; the inner diameter d of the first water inlet section 2121 is smaller than the inner diameter D of the second water inlet section 2122; the water mixing chamber 214 includes a first water mixing section 2141 and a second water mixing section 2142 sequentially arranged along the water inlet direction; the inner diameter w of the first water mixing section 2141 is smaller than the inner diameter W of the second water mixing section 2142, and the inner diameter w of the first water mixing section 2141 is larger than the inner diameter D of the second water inlet section 2122, so that in the water inlet direction, the water flow undergoes three changes in the water flow area, and the change in the water flow area can generate negative pressure inside the water inlet channel 212 to attract external air, so that the gas content in the bubble water is increased. Specifically, the first water inlet section 2121 is located in the upper body 217, and the second water inlet section 2122, the first water mixing section 2141 and the second water mixing section 2142 are all located in the lower body 218.

[0099] In some embodiments, the rectifying grid includes circular ribs and a plurality of straight ribs; the straight ribs are distributed along the radial direction of the circular ribs, so that the straight ribs and the circular ribs form rectifying holes. Optionally, there are two circular ribs, and the two circular ribs have different diameters and are coaxially arranged, and the straight ribs are arranged in sequence along the radial direction of the circular ribs to make the two circular ribs cross the straight ribs.

[0100] In some embodiments, at least one side of the rectifying grid in the axial direction is provided with a protrusion, and the setting of the protrusion can support the water flow segmentation component 221, so that a distance is formed between the water flow segmentation component 221 and the rectifying hole, so that the water flow cut by the screen 2211 passes through a certain free space before continuing to be rectified by the rectifying grid, which is conducive to making the shape of the water spray more rounded. Preferably, a plurality of protrusions are respectively provided on both sides of the rectifying grid.

[0101] In some embodiments, the protrusion is disposed at the intersection of the straight ribs and the circular ribs.

[0102] In some embodiments, when the water outlet panel 22 is used in a non-flippable scenario, that is, the water outlet panel 22 cannot be flipped relative to the water outlet device 2, there is a distance between the water flow dividing component 221 and the inner wall of the panel body 225 in the circumferential direction of the water outlet panel 22. When the water contains impurities, they can be washed away from the edge of the screen 2211 and discharged from the outside of the panel to avoid clogging of the screen 2211.

[0103] In other embodiments, another water outlet device 2 is provided, including a water inlet component 21 and a water outlet panel 22; the water outlet panel 22 is arranged in the water outlet 211 of the water inlet component 21; the water inlet component 21 has a water inlet channel 212, an air inlet channel 213 and a mixing water chamber 214; the air inlet channel 213 is surrounded by a plurality of first air outlets 215; the first air outlets 215 surround the side wall of the water inlet channel 212, and the first air outlets 215 are connected to the water inlet channel 212, and the water inlet channel 212 is connected to the mixing water chamber 214; the water outlet panel 22 has a water flow dividing component 221 coaxially arranged with the water inlet component 21, and the mesh number of the water flow dividing component 221 is 200 to 1000 meshes.

[0110] In some embodiments, the water inlet channel 212 includes a first water inlet section 2121 and a second water inlet section 2122 sequentially arranged along the water inlet direction; the inner diameter d of the first water inlet section 2121 is smaller than the inner diameter D of the second water inlet section 2122; the water mixing chamber 214 includes a first water mixing section 2141 and a second water mixing section 2142 sequentially arranged along the water inlet direction; the inner diameter w of the first water mixing section 2141 is smaller than the inner diameter W of the second water mixing section 2142, and the inner diameter w of the first water mixing section 2141 is larger than the inner diameter D of the second water inlet section 2122, so that in the water inlet direction, the water flow undergoes three changes in the water flow area, and the change in the water flow area can generate negative pressure inside the water inlet channel 212 to attract external air, so that the gas content in the bubble water is increased. Specifically, the first water inlet section 2121 is located in the upper body 217, and the second water inlet section 2122, the first water mixing section 2141 and the second water mixing section 2142 are all located in the lower body 218.

[0111] In this embodiment, the water outlet panel 22 also includes a rectifying bracket 224, a panel body 225 and a cover body 226; the rectifying bracket 224 is coaxially arranged with the panel body 225 and embedded in the panel body 225, and the cover body 226 is covered on the side of the rectifying bracket 224 away from the panel body 225; in the axial direction of the panel body 225, a water flow dividing component 221 is respectively sandwiched between the rectifying bracket 224 and the cover body 226 and between the rectifying bracket 224 and the panel body 225; in the axial direction of the panel body 225, a water inlet grille 227 is respectively provided on the side of the cover body 226 facing the water flow dividing component 221 and on the side of the panel body 225 facing the water flow dividing component 221. Among them, the rectifying bracket 224 is also provided with a water-passing grid for water flow to pass through; the rectifying grid includes two circular ribs and eight straight ribs; the straight ribs are distributed along the radial direction of the circular ribs, so that the straight ribs and the circular ribs form rectifying holes; the two circular ribs have different diameters and are concentrically arranged, and the straight ribs pass through the two circular ribs in sequence along the radial direction of the circular ribs, so that the two circular ribs cross the straight ribs; the rectifying grid is provided with a plurality of protrusions on both sides in the axial direction, and the protrusions are arranged at the intersection of the straight ribs and the circular ribs.

[0112] The working principle of this embodiment is:

[0113] The water flows from the water inlet channel 212 into the water mixing chamber 214. According to the Venturi principle, the water flows from the first water inlet section 2121 into the second water mixing section 2142, and the inner diameter changes three times. The change of the inner diameter will change the water flow area, thereby generating negative pressure in the water inlet channel 212. The air passes through the air intake channel 11, the air intake hole 2191 and the air inlet channel 213 in sequence, and then enters the water inlet channel 212 from the first air outlet 215 and the second air outlet 216 to mix with the water.

[0114] At the same time, due to the setting of the water flow dividing component 221, the water flow discharge resistance is increased. When a part of the water flow passes through the water outlet panel 22 and is discharged, the large bubbles in the water flow are cut into micro bubbles by the screen 2211, forming the discharge of micro bubble water flow; the other part of the water flow cannot be discharged due to the obstruction of the water flow dividing component 221 and flows back along the inner wall of the lower main body 218, and when this part of the water flow contacts the top of the inner wall of the lower main body 218, it flows toward the water outlet panel 22 again, and repeats this cycle. During this cycle, due to the existence of negative pressure in the mixing water chamber 214, the returning water flow continuously inhales air to further increase the air-water mixing ratio, so that the water flow passing through the screen 2211 carries more large bubbles that can be cut, and finally the bubble water discharged outward is filled with sufficient, uniform and long-lasting micro bubbles.

When the boss is pressed against the inner wall of the upper main body 217, the first air outlet 215 is formed, and the second air outlet 216 is opened on the circumferential side wall of the protrusion.

[0125] The working principle of this embodiment is:
