Description

Technical Field

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

[0002] A smart toilet is a sanitary ware equipped with functions such as washing, seat heating, warm air drying, and sterilization. Based on the washing function, there are different categories such as posterior wash and feminine wash. However, regardless of the type of washing, the washing water needs to have a good contact effect when it comes into contact with the user to reduce discomfort.

[0003] Based on this, in related technologies, on the one hand, warm water can be used for cleaning by adjusting the water temperature; on the other hand, sparkling water can be used for cleaning. Sparkling water not only has stronger cleaning power, but also makes cleaning more comfortable and gentle when it comes into contact with the human body. However, the sparkling water generated by smart toilets at present has large bubbles and few bubbles, resulting in a poor user experience. Utility Model Content

[0004] The purpose of this invention is to provide a nozzle, water outlet device, and toilet that makes the sparkling water more concentrated and gentle, thus improving the user experience.

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

[0006] The nozzle includes:

[0007] A base, wherein a first flow cavity is provided inside the base, and a first water inlet and a first water outlet are also provided on the base, wherein the first water inlet and the first water outlet are both connected to the first flow cavity;

[0008] A plurality of blocking blocks are spaced apart in the first flow cavity from the first inlet to the first outlet, and there is a gap between the blocking blocks and the side wall of the first flow cavity.

[0009] In some embodiments, the distance between two adjacent blocking blocks is a, 2mm≤a≤5mm; and / or, the distance between the blocking blocks and the side wall of the first flow cavity is b, 0.7mm≤b≤1.5mm.

[0010] In some embodiments, the base includes a first seat and a second seat that are joined together, the first seat having a first half-groove, the second seat covering the first half-groove to form the first flow cavity, and the blocking block being fixed to the bottom of the first half-groove.

[0011] In some embodiments, the blocking block is cylindrical.

[0012] In some embodiments, the first flow cavity includes a long cavity section and a short cavity section, the short cavity section is connected to the long cavity section and is set at an angle to the long cavity section, the first water inlet is connected to the long cavity section, the first water outlet is connected to the short cavity section, and the blocking block is disposed in the long cavity section.

[0013] In some embodiments, the nozzle includes a first guide block, a third guide block, and a second guide block arranged sequentially in a direction away from the first water inlet. The first guide block is disposed downstream of the blocking block and on one side wall of the long cavity section. The second guide block is disposed on the other side wall of the long cavity section. The first guide block is provided with a first guide surface, which gradually moves away from the side wall on which the first guide block is disposed from the direction close to the first water inlet toward the direction away from the first water inlet. The third guide block is disposed between the first guide block and the second guide block. The third guide block and the first guide block clamp together to form a first water channel, and the second guide block and the third guide block clamp together to form a second water channel. The first water channel and the second water channel are inclined so that the water flow in the first water channel and the second water channel converges into the short cavity section.

[0014] In some embodiments, the nozzle further includes an impact block disposed in the short cavity section, the impact block being spaced apart from the third guide block, the impact block having a gap with the side wall of the short cavity section, and the first water channel and the second water channel being able to converge the water flow to the impact block.

[0015] In some embodiments, the distance between the impact block and the third guide block is c, 0.7mm≤c≤1mm; and / or, the distance between the impact block and the sidewall of the short cavity segment is d, 0.7mm≤d≤1mm.

[0016] On the other hand, a water outlet device is also provided, which includes the nozzle as described above.

[0017] Another option is a toilet that uses the aforementioned water outlet device.

[0018] The beneficial effects of this utility model are:

[0019] When water containing air bubbles flows from the first inlet to the first outlet, it passes through the baffle block and impacts the block, intensifying the collision and splitting of the air bubbles. After the impact, the water flow is diverted by the baffle block, causing it to converge downstream of the baffle block through the gaps between the sides of the baffle block and the side walls of the first flow chamber. Furthermore, after the water flow impacts the baffle block, a fluid oscillation wake appears upstream of the baffle block, creating turbulence. When the water containing air bubbles collides with the turbulence, it further intensifies the collision and splitting of the air bubbles, resulting in a greater number of microbubbles. This makes the bubbly water sprayed from the first outlet more concentrated and gentle, improving the user experience. Attached Figure Description

Detailed Implementation

[0027] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[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 or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or 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 according to the specific circumstances.

[0029] In the description of this utility model, unless otherwise expressly 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] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1 to 5 As shown, this utility model provides a nozzle, which includes a base 1 and a blocking block 5. The base 1 is provided with a first flow cavity 2, and the base 1 is also provided with a first water inlet and a first water outlet 3. The first water inlet and the first water outlet 3 are both connected to the first flow cavity 2. A plurality of blocking blocks 5 are arranged at intervals in the first flow cavity 2 from the first water inlet to the first water outlet 3, and there is a gap between the blocking blocks 5 and the side wall of the first flow cavity 2.

[0032] Multiple baffles 5 are installed in the first flow chamber 2. When water containing air bubbles flows from the first inlet to the first outlet 3, it can pass through the baffles 5 and collide with them. This intensifies the collision and splitting of the air bubbles. After the collision, the water flow is diverted by the baffles 5 and flows downstream of the baffles 5 through the gap between the baffles 5 and the side walls of the first flow chamber 2. Furthermore, after the water flow collides with the baffles 5, a fluid oscillation wake (also known as a Karman vortex street) appears on the upstream side of the baffles 5, forming turbulence. When the water containing air bubbles collides with the turbulence, it also intensifies the collision and splitting of the air bubbles, thus forming more microbubbles. This makes the bubble water sprayed from the first outlet 3 more concentrated and gentle, improving the user experience.

[0033] In some embodiments, the blocking block 5 is cylindrical, so that the water flow can pass through the gaps on both sides more smoothly after hitting the blocking block 5, minimizing the resistance to passing through; at the same time, setting the blocking block 5 as cylindrical can also reduce dead corners, thereby minimizing the formation of scale.

[0034] like Figure 1 As shown, for example, the distance between two adjacent blocking blocks 5 is a, 2mm≤a≤5mm, for example, 2mm, 3mm, 4mm, etc. If the distance is too small, it will block the flow of water, thus forming a flow restriction; if the distance is too large, it will affect the impact of the bubble water, thus affecting the impact effect.

[0035] The distance between the blocking block 5 and the side wall of the first flow passage 2 is b, 0.7mm≤b≤1.5mm, for example, it can be 0.9mm, 1mm, 1.2mm, etc. If the above distance is too large, the flow speed of the water will decrease when it flows from both sides of the blocking block 5, and the low speed will affect the impact effect; if the above distance is too small, it will restrict the flow and cause the water flow to be obstructed.

[0036] like Figure 1 As shown, in some embodiments, the base 1 includes a first seat 11 and a second seat 12 that are joined together. The first seat 11 has a first half-groove, and a blocking block 5 is disposed in the first half-groove. When the first seat 11 and the second seat 12 are joined together, the second seat 12 covers the opening of the first half-groove, thereby forming a complete first flow cavity 2. A first outlet 3 is disposed on the second seat 12, and a first inlet is also disposed on the second seat 12. The first inlet is connected to a connector 10 for easy connection to a water pipe to receive bubble water. To reduce interference, the first inlet and the first outlet 3 correspond to the two ends of the first half-groove, respectively. In other alternative embodiments, the second seat 12 has a second half-groove. When the first seat 11 and the second seat 12 are joined together, the first half-groove and the second half-groove are combined to form a complete first flow cavity 2.

[0037] In some embodiments, the first flow cavity 2 can be a linear cavity.

[0038] like Figure 1As shown, in some embodiments, to improve applicability, a second flow cavity 20 is also provided inside the base 1, and a second inlet and a second outlet 4 communicating with the second flow cavity 20 are provided on the base 1, so that ordinary water or disinfectant water can flow through the second flow cavity 20, providing users with more choices and applicability. The second inlet is also provided with a connector 10. For easier use, the first outlet 3 and the second outlet 4 are located in the middle of the base 1. In addition, the first inlet and the second inlet are located on the same side of the base 1, so as to avoid interference between the first flow cavity 2 and the second flow cavity 20. The line connecting the first outlet 3 and the second outlet 4 is in the same direction as the extension direction of the connector 10, so as to facilitate connection. In the current embodiment, the first flow cavity 2 includes a long cavity section and a short cavity section, wherein the short cavity section is connected to the side of the long cavity section, so that the short cavity section and the long cavity section are set at an angle to form an L-shape; the second flow cavity 20 can be a straight cavity or a bent cavity, without specific limitation.

[0039] like Figure 1 As shown, in some embodiments, the blocking block 5 is located within the long cavity section. When the downstream blocking block 5 is located at the junction of the long cavity section and the short cavity section, the size of the blocking block 5 at this location can be larger than that of other blocking blocks 5 due to the larger space there. The specific size can be adjusted according to different positions and is not specifically limited.

[0040] Based on the aforementioned L-shaped first flow cavity 2, the blocking block 5 is located within the long cavity section; as... Figure 3 and Figure 4As shown, in some embodiments, the nozzle further includes a first guide block 6, a third guide block 8, and a second guide block 7 arranged sequentially in a direction away from the first water inlet. The first guide block 6 is located downstream of the blocking block 5, and thus, the second guide block 7 and the third guide block 8 are also located downstream of the blocking block 5. The first guide block 6 is located on one side wall of the long cavity section and has a first guide surface 61. The first guide surface 61 gradually moves away from the side wall where the first guide block 6 is located from the direction near the first water inlet to the direction away from the first water inlet. The second guide block 7 is located on the other side wall of the long cavity section, and the third guide block 8 is located between the first guide block 6 and the second guide block 7. The second guide block 7 and the first guide block 6 clamp together to form a first water channel, and the second guide block 7 and the first guide block 6 clamp together to form a second water channel. The first water channel and the second water channel are inclined so that the first water channel and the second water channel can... The water flows converge into the short cavity section. Thus, when the water flow passes the last blocking block 5 and impacts downstream of the blocking block 5, one stream flows towards the first guide surface 61, and the other stream advances along the side cavity wall where the second guide block 7 is located. Based on the guidance of the first guide surface 61, the water flow advancing along the first guide surface 61 will impact the other stream again, splitting into two streams. One stream flows towards the first water channel formed by the clamping of the third guide block 8 and the first guide block 6, while the other stream flows towards the second water channel formed by the clamping of the third guide block 8 and the second guide block 7. Since the first and second water channels are inclined, the water flows in the first and second water channels can converge into the short cavity section, and then the two streams will impact each other again in the short cavity section. Thus, after the water flow passes the blocking block 5, it will impact multiple times again through the action of the first guide block 6, the second guide block 7, and the third guide block 8, further forming a greater number of microbubbles.

[0041] like Figure 4 As shown, by way of example, the third guide block 8 is provided with a second guide surface 81 and a third guide surface 82 on opposite sides. The second guide surface 81 faces the first guide block 6 and the second guide surface 82 faces the second guide block 7. The second guide surface 81 and the third guide surface 82 gradually move closer to each other from away from the short cavity segment to closer to the short cavity segment. In order to facilitate guidance, the first guide block 6 is also provided with a fourth guide surface 62 that cooperates with the second guide surface 81 in the same direction. The first water channel is located between the second guide surface 81 and the fourth guide surface 62. The second guide block 7 is provided with a fifth guide surface 71 that cooperates with the third guide surface 82 in the same direction. The second water channel is located between the third guide surface 82 and the fifth guide surface 71.

[0042] In some embodiments, the nozzle further includes an impact block 9, which is disposed in the short cavity section. The impact block 9 is spaced apart from the third guide block 8 and is located between the third guide block 8 and the first water outlet 3. The first water channel and the second water channel can converge the water flow to the impact block 9, thereby improving the impact effect of the water flow and generating as many microbubbles as possible. In addition, there is a gap between the impact block 9 and the side cavity wall of the short cavity section, so that the water flow after impact flows from both sides of the impact block 9 to the first water outlet 3.

[0043] like Figure 3 As shown, for example, the distance between the impact block 9 and the third guide block 8 is c, 0.7mm≤c≤1mm; for example, 0.9mm, 1mm or 1.2mm can be used. If the distance is too small, it will block the water flow, thus limiting the flow; if the distance is too large, it will affect the impact effect. The distance between the impact block 9 and the side wall of the short cavity section is d, 0.7mm≤d≤1mm; for example, 1mm, 1.1mm or 1.2mm can be used. If the distance is too small, it will limit the flow, resulting in poor water flow; if the distance is too large, it will result in a low water flow velocity, thus affecting the water output velocity.

[0044] This utility model also provides a toilet with a water outlet device, which includes an aerator and a nozzle as described above. The outlet of the aerator is connected to a first water inlet, thereby supplying water with bubbles, i.e., bubbly water, to the nozzle. The nozzle, through a blocking block 5 in the first flow chamber 2, further collidees and breaks the bubbly water to form more microbubbles, thus making the bubbly water sprayed from the first outlet 3 more concentrated and gentle, improving the user experience. Alternatively, in another embodiment, the water outlet device may also include a supply pipe with two inlets and one outlet. One inlet is connected to an air source, the other to a water source, and the outlet is connected to the nozzle, thereby directly supplying water and gas through the supply pipe to form bubbly water.

[0045] Understandably, the above-mentioned nozzles can also be used in other devices that require water output, such as shower heads and faucets.

[0046] 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 other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
