Description

Technical Field

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

[0002] Micro-nano bubble water refers to water containing a large number of micro-nano bubbles with diameters ranging from 10nm to 400nm and from 1μm to 50μm (standard term: microbubbles). Micro-nano bubble water is widely used in industrial water treatment and water pollution treatment, and is now gradually being applied in daily life and beauty products.

[0003] However, the micro-nano bubble water produced by the existing micro-nano bubble water outlet structure is unstable, has low density, and low water flow, making bathing uncomfortable.

[0004] Urban water supply uses pressurized water supply, which already contains some dissolved air. A specialized micro-nano bubble water outlet structure releases this dissolved air, forming micro-nano bubbles. When paired with a micro-nano bubble water machine equipped with an air-dissolving device, it can release a large flow of micro-nano bubble water from the saturated air dissolved in the water.

[0005] In the existing structures, the micro-nano bubble water output structure is relatively complex, resulting in low concentration of micro-bubble water, large bubble particle size, and poor bubble visualization. Utility Model Content

[0047] Dissolved air water often uses a dissolving device to dissolve air into water. Before using dissolved air water, a micro-nano bubble generator is used to release micro-nano bubbles from the dissolved air water, so that when the user uses the water, the concentration of micro-bubble water exiting from the water outlet structure is relatively high.

[0048] In some existing structures, considering the small flow rate of micro-nano bubble water, either ordinary flow holes are provided on the micro-nano bubble generator, or a gap flow channel is formed between the micro-nano bubble generator and the main body of the water outlet structure, and water is directly discharged using the flow holes or the gap flow channel to supplement the insufficient flow rate of the water.

[0049] Directly discharging dissolved air water during the above process will result in low concentration of microbubbles, large bubble size, and low bubble visibility from the water outlet structure.

[0050] In view of this, the present invention proposes a water outlet structure, wherein, Figures 1 to 9 A schematic diagram of the water outlet structure provided by this utility model.

[0051] Please see Figure 1 This utility model proposes a water outlet structure 100, which includes a water outlet body 1 and a micro-nano bubble generator 2. A water outlet channel 11 is formed on the water outlet body 1, and the water outlet channel 11 penetrates the water outlet body 1 to form a water outlet hole 12.

[0052] The micro-nano bubble generator 2 is located on the water outlet body 1 and within the water outlet channel 11. A flow channel 21 is formed on the micro-nano bubble generator 2. The dissolved air water introduced into the water outlet body 1 can only pass through the flow channel 21 and then exit from the water outlet hole 12. The flow channel 21 is configured to release micro-nano bubbles in the dissolved air water through the Venturi effect.

[0053] In the technical solution of this utility model, the water outlet structure 100 includes a water outlet body 1 and a micro / nano bubble generator 2. A water outlet channel 11 is formed on the water outlet body 1, and the water outlet channel 11 penetrates the water outlet body 1 to form a water outlet hole 12. The micro / nano bubble generator 2 is disposed on the water outlet body 1 and is located within the water outlet channel 11. A device channel 21 is formed on the micro / nano bubble generator 2. The dissolved air water introduced into the water outlet body 1 can only pass through the device channel 21 and then exit from the water outlet hole 12. The device channel 21 is configured to release micro / nano bubbles in the dissolved air water through the Venturi effect. After all the dissolved air water in the water outlet body 1 passes through the device channel 21, the micro / nano bubbles in the dissolved air water are fully and completely released, which increases the concentration of microbubble water, the bubble particle size is small, and the bubble visualization effect is good.

[0054] The process by which dissolved water releases micro-nano bubbles through the Venturi effect within the flow channel 21 of the micro-nano bubble generator 2 can be understood as follows:

[0055] When dissolved air water is introduced into the main water outlet 1, it enters the flow channel 21 of the micro / nano bubble generator 2, which forms a Venturi tube-like structure. As the dissolved air water flows through the flow channel 21, the water flow velocity increases and the pressure decreases accordingly. This causes the gas molecules in the dissolved air water to expand due to the pressure difference and form microbubbles. These microbubbles are further refined under the Venturi effect, eventually transforming into micro / nano-sized bubbles. When the dissolved air water passes through the outlet of the flow channel 21, i.e., the water outlet 12, these micro / nano bubbles are released into the external environment along with the water flow. This process ensures that the gas in the dissolved air water is fully released and transformed into high-concentration microbubble water, thereby improving the visibility of the bubbles and enhancing the application efficiency of the bubbles.

[0056] It is understood that the water outlet channel 11 extends through the water outlet body 1 to form the water outlet hole 12, and the micro / nano bubble generator 2 is also located on the water outlet body 1, making the micro / nano bubble generator 2 closer to the water outlet hole 12. This allows the bubble water passing through the micro / nano bubble generator 2 to exit quickly, reducing pressure loss and time delay during the water exiting process. This design not only optimizes the bubble release efficiency but also ensures that the bubble water maintains a high concentration of micro / nano bubbles when leaving the water outlet structure 100. Simultaneously, because the micro / nano bubble generator 2 is close to the water outlet hole 12, the bubble water maintains a small particle size and high visibility during the outflow process, which is extremely beneficial for the application effect and user experience of micro / nano bubble water.

[0057] In some embodiments, please refer to Figures 1 to 4 The present invention provides a schematic diagram of the structure of the first embodiment of the water outlet structure 100. In the first embodiment, the water outlet body 1 is set as a shower body 1a, which is mainly used in shower equipment.

[0058] Specifically, the water outlet channel 11 of the shower head body 1a includes a first water outlet channel 111 and a second water outlet channel 112 that are interconnected. The first water outlet channel 111 extends laterally, and the micro-nano bubble generator 2 is disposed in the first water outlet channel 111. The second water outlet channel 112 extends longitudinally, and the water outlet hole 12 is located on the second water outlet channel 112.

[0059] With this configuration, when the micro-nano bubble water flows through the first outlet channel 111, it can completely pass through the micro-nano bubble generator 2, generating abundant micro-nano bubbles. Subsequently, the bubble water enters the second outlet channel 112, which extends longitudinally. The micro-nano bubble water can maintain a stable flow rate and pressure during the outflow process, ensuring the stability and concentration of the micro-nano bubbles.

[0060] Furthermore, the shower head body 1a is often designed as a flat structure with a smaller dimension in the thickness direction. Therefore, placing the first water outlet channel 111 horizontally and placing the micro-nano bubble generator 2 inside the first water outlet channel 111 is beneficial for the structure design and can effectively utilize the internal space of the shower head body 1a.

[0061] It is understandable that the horizontal and vertical directions are two intersecting directions, which can be perpendicular to each other, or they can intersect at an acute angle or an obtuse angle.

[0062] It should be noted that in the shower head body 1a, no other structure may be provided between the micro / nano bubble generator 2 and the water outlet 12. This arrangement minimizes water flow resistance, ensuring smooth flow of micro / nano bubble water, while avoiding interference and damage to the micro / nano bubbles from other structures, thus guaranteeing bubble stability and performance. Furthermore, this simple design facilitates later maintenance and cleaning, extending the product's lifespan.

[0063] In some embodiments, a shower handle 3 is connected to the end of the shower body 1a away from the water outlet 12. The shower handle 3 not only facilitates user grip and operation but also enhances the overall aesthetics. The shape and size of the shower handle 3 can be optimized according to ergonomics to ensure user comfort during use. Furthermore, the interior of the shower handle 3 can be designed as a hollow structure to further reduce overall weight without compromising structural strength. The surface of the shower handle 3 can also be provided with anti-slip textures or protrusions to increase friction during grip and prevent slippage. In some embodiments, the shower handle 3 can also be connected to the shower body 1a via a threaded connection, snap-fit ​​connection, or other detachable connection method, facilitating user replacement or cleaning according to actual needs.

[0064] In some embodiments, the micro-nano bubble generator 2 is disposed adjacent to the shower handle 3. With this arrangement, dissolved air water entering the shower body 1a through the shower handle 3 directly enters the micro-nano bubble generator 2. After the micro-nano bubble generator 2 releases the micro-nano bubbles, the water directly exits through the water outlet 12, making the water flow path more direct and efficient, reducing the flow distance and time of the water inside the shower head, thereby improving the generation efficiency of micro-nano bubbles and the water output speed.

[0065] The micro-nano bubble generator 2 is mounted on the shower head body 1a. It can be fixedly connected, such as by structural adhesive, or detachably connected, such as by threaded connections or snap-fit ​​connections, to facilitate user maintenance or replacement of the micro-nano bubble generator 2. This design not only improves the practicality of the shower head but also increases its flexibility and convenience. Furthermore, the connection method between the micro-nano bubble generator 2 and the shower head body 1a can be selected according to actual needs to meet the usage habits and requirements of different users.

[0066] In some embodiments, the micro-nano bubble generator 2 is installed using a limiting installation method, and can be disassembled by releasing the limiting. Compared with threaded connection and snap-fit ​​connection, installation and disassembly are extremely simple.

[0067] Specifically, a first limiting step surface 1111 is formed in the first water outlet channel 111, facing away from the second water outlet channel 112.

[0068] The end of the shower handle 3 extends into the first water outlet channel 111.

[0069] The micro-nano bubble generator 2 is detachably installed on the shower body 1a, and is at least partially confined between the end face of the shower handle 3 and the first limiting step surface 1111.

[0070] When forming the shower body 1a, the first limiting step surface 1111 can be formed. For example, when the shower body 1a is injection molded, the relevant structure can be directly set in the injection mold to form the shower body 1a with the first limiting step surface 1111 in one step.

[0071] Alternatively, the first limiting step surface 1111 can be formed by machining, such as by turning. During the machining process, the size and position of the first limiting step surface 1111 can be precisely controlled to ensure that the micro-nano bubble generator 2 can be stably and firmly installed on the shower body 1a.

[0072] The end of the shower handle 3 extends into the first water outlet channel 111. At this time, the end of the shower handle 3 limits the outward movement of the micro-nano bubble generator 2, and the first limiting step surface 1111 limits the inward movement of the micro-nano bubble generator 2, thereby achieving stable installation of the micro-nano bubble generator 2 on the shower body 1a.

[0073] When it is necessary to disassemble the micro-nano bubble generator 2, the user only needs to pull the shower handle 3 out of the first water outlet channel 111 to release the restriction on the micro-nano bubble generator 2, and then easily remove the micro-nano bubble generator 2 from the shower body 1a. This restriction installation method not only simplifies the installation and disassembly steps, but also improves the user's ease of operation.

[0074] The micro / nano bubble generator 2 is at least partially confined between the end face of the shower handle 3 and the first limiting step surface 1111. The micro / nano bubble generator 2 can be entirely confined between the end face of the shower handle 3 and the first limiting step surface 1111, or it can be partially confined between the end face of the shower handle 3 and the first limiting step surface 1111. In the partial confining method, a protrusion is formed on the outer side of the micro / nano bubble generator 2, and the installation of the entire micro / nano bubble generator 2 is limited by the confining installation of the protrusion.

[0075] Furthermore, since the micro-nano bubble generator 2 is installed on the shower body 1a by means of limiting, there is no need to use additional fasteners such as screws or clips, which further reduces production costs and simplifies the structure of the product.

[0076] All dissolved air water introduced into the water outlet body 1 passes through the flow channel 21. The micro-nano bubble generator 2 needs to be sealed and installed in the first water outlet flow channel 111. A sealing structure needs to be set between the micro-nano bubble generator 2 and the first water outlet flow channel 111 to ensure that the dissolved air water does not leak when flowing through the flow channel 21, thereby ensuring the stability and reliability of the water outlet structure 100.

[0077] The sealing structure can be made of highly elastic sealing materials, such as silicone or rubber. These materials not only have good sealing performance but can also accommodate the minute movements of the micro / nano bubble generator 2 within the first water outlet channel 111, thus avoiding sealing failure due to long-term use or installation errors. Furthermore, the installation and disassembly of the sealing structure are very simple; users can easily replace and maintain it, further improving the product's usability and durability.

[0078] The installation method of the sealing structure is also unrestricted. For example, in the installation method of using a sealing ring for sealing, the sealing ring can be directly sleeved on the outside of the micro-nano bubble generator 2, such as by adhesive bonding; or an installation groove can be set on the micro-nano bubble generator 2, and the sealing ring can be sleeved in the installation groove, which improves the stability and firmness of the sealing structure.

[0079] Of course, during installation, a combination of mounting groove and sealant can also be used, such as applying an appropriate amount of sealant between the sealing ring and the micro-nano bubble generator 2 to enhance the sealing effect.

[0080] Furthermore, multiple sealing rings can be disposed on the outside of the micro / nano bubble generator 2 to further enhance the sealing effect. The multiple sealing rings provide multiple layers of sealing protection; even if one sealing ring wears or ages, the others can still maintain an effective seal, thus significantly extending the service life of the entire sealing structure. Simultaneously, the multiple sealing rings also increase the contact area between the sealing structure and the micro / nano bubble generator 2, improving the tightness and stability of the seal. The appropriate number of sealing rings and installation method can be selected as needed to meet different sealing requirements.

[0081] In some embodiments, please refer to Figures 5 to 9 The present invention provides schematic diagrams of the second and third embodiments of the water outlet structure 100. In the second and third embodiments, the water outlet body 1 is set as a faucet body 1b, which is mainly used in water-using places such as kitchens or bathrooms.

[0082] In some embodiments, the water outlet body 1 includes a faucet body 1b, and the water outlet channel 11 of the faucet body 1b extends longitudinally. This arrangement allows the water to maintain a certain pressure and flow rate when flowing out, thereby improving the efficiency and comfort of water use. Simultaneously, the longitudinal extension of the water outlet channel 11 of the faucet body 1b also allows for greater flexibility in the water outlet direction, making it convenient for users to adjust the direction and angle of the water flow as needed.

[0083] It should be noted that in the faucet body 1b, no other structure may be provided between the micro / nano bubble generator 2 and the water outlet 12. This arrangement minimizes water flow resistance, ensuring smooth flow of micro / nano bubble water, while avoiding interference and damage to the micro / nano bubbles from other structures, thus guaranteeing bubble stability and effectiveness. Furthermore, this simple design facilitates later maintenance and cleaning, extending the product's lifespan.

[0084] The micro-nano bubble generator 2 is disposed on the faucet body 1b, and can be fixedly connected, such as by structural adhesive; or it can be detachably connected, such as by threaded connection or snap-fit ​​connection, to facilitate user maintenance or replacement of the micro-nano bubble generator 2. This design not only improves the practicality of the faucet but also increases its flexibility and convenience of use. Furthermore, the connection method between the micro-nano bubble generator 2 and the faucet can be selected according to actual needs to meet the usage habits and requirements of different users.

[0085] In some embodiments, the micro-nano bubble generator 2 is installed using a limiting installation method, and can be disassembled by releasing the limiting. Compared with threaded connection and snap-fit ​​connection, installation and disassembly are extremely simple.

[0086] For details, please refer to the following: Figure 6 The faucet body 1b includes a housing 113, which is hollow. A water distribution body 114 is provided at the end of the housing 113. The water outlet 12 is provided in the water distribution body 114. The water outlet channel 11 of the faucet body 1b includes the inner cavity of the housing 113 and the water outlet 12. A second limiting step surface 1131 facing the water distribution body 114 is formed inside the housing 113.

[0087] The micro-nano bubble generator 2 is detachably installed on the faucet body 1b and is located between the end face of the water flow distribution body 114 and the second limiting step surface 1131.

[0088] The aforementioned limiting installation method not only ensures the stability of the micro-nano bubble generator 2 during installation, preventing it from shaking or falling off during operation, but also greatly improves ease of use because the installation and disassembly process is simple and quick, allowing users to complete the operation without the need for complicated tools.

[0089] Furthermore, the second limiting step surface 1131 provides a precise positioning reference for the micro-nano bubble generator 2, ensuring its positional accuracy after installation, thereby guaranteeing the stable generation and output of the micro-nano bubbles.

[0090] The second step surface is formed inside the housing 113. When the faucet body 1b is formed, the second limiting step surface 1131 can be formed. For example, when the faucet body 1b is injection molded, the relevant structure can be directly set in the injection mold to form the faucet body 1b with the second limiting step surface 1131 in one step.

[0091] Alternatively, the second limiting step surface 1131 can be formed by machining, such as by turning. During machining, the size and position of the second limiting step surface 1131 can be precisely controlled to ensure that the micro-nano bubble generator 2 can be stably and firmly installed on the faucet body 1b.

[0092] The water flow distribution body 114 serves to evenly distribute the water in the water outlet channel 11, ensuring that the water flow from the water outlet 12 is uniform and stable. This effectively avoids uneven distribution of water flow in the water outlet channel 11, improves the user's water experience, and makes the water flow more gentle and comfortable.

[0093] In some embodiments, the flow distribution body is configured as a cover plate, with an installation port provided on the housing 113. The cover plate covers the installation port, and the water outlet 12 is disposed on the cover plate. This configuration allows the cover plate to be processed separately, so that the water outlet 12 can be directly formed on the cover plate, making processing and forming convenient.

[0094] It is understood that the connection between the cover plate and the housing 113 can be a threaded connection, a snap-fit ​​connection, or the like.

[0095] In an embodiment where the water distribution body 114 serves to limit the micro / nano bubble generator 2, specifically, the water distribution body 114 includes a distribution body 1141 and a plurality of abutting protrusions 1142 extending from the distribution body 1141 toward the second limiting step surface 1131, and the micro / nano bubble generator 2 is limited between the end faces of the plurality of abutting protrusions 1142 and the second limiting step surface 1131.

[0096] A flow gap 1143 is formed between two adjacent abutting protrusions 1142, and the water outlet channel 11 includes the flow gap 1143.

[0097] By providing the abutment protrusions 1142, the micro / nano bubble generator 2 can be limited, and the smooth flow of water in the water outlet channel 11 can be ensured, preventing obstruction of the water flow. Simultaneously, the multiple abutment protrusions 1142 increase the contact area between the water distribution body 114 and the micro / nano bubble generator 2, improving the stability of the limiting action. Furthermore, the shape and size of the abutment protrusions 1142 can be designed according to actual needs to accommodate different models of the micro / nano bubble generator 2, improving the versatility and practicality of the faucet structure.

[0098] The flow channel 21 is configured to release micro-nano bubbles in the dissolved air water through the Venturi effect. Specifically, the flow channel 21 includes multiple Venturi orifices. By providing multiple Venturi orifices, the number of release points for micro-nano bubbles can be increased, improving the release efficiency and uniformity of micro-nano bubbles in the dissolved air water. Furthermore, the multiple Venturi orifices can also increase the flow rate of the water outlet structure 100, meeting the user's water flow requirements.

[0099] The arrangement of the multiple Venturi holes on the micro / nano bubble generator 2 is unrestricted and can be flexibly arranged according to actual needs. For example, multiple Venturi holes can be arranged in a specific pattern, such as at a certain angle or spacing, to achieve a specific micro / nano bubble release effect. This arrangement not only improves the flexibility and adaptability of the water outlet structure 100, but also further enhances its practicality and market competitiveness.

[0100] In some embodiments, the specific structure of the flow channel 21 is further defined; please refer to the detailed description. Figure 9 Specifically, the venturi orifice has a tapered section 211, a throat 212, and a diffuser section 213 arranged sequentially in its extending direction. The tapered section 211 allows the water flow to gradually accelerate as it enters the venturi orifice, forming a high-speed water flow. The throat 212, as the part where the water flow velocity reaches its maximum, has a narrow space that causes the water flow to be subjected to strong shear force, thereby promoting the release of micro-nano bubbles in the dissolved air water. The diffuser section 213 is responsible for gradually slowing down and diffusing the high-speed water flow passing through the throat 212, so that the micro-nano bubbles can be evenly distributed in the discharged water.

[0101] Specifically, the cone angle of the tapered section 211 is α, where 0° < α ≤ 60°. This setting ensures that the water flow can accelerate smoothly and effectively within the tapered section 211, reducing water flow turbulence or resistance. Simultaneously, this cone angle design can also reduce the impact of the water flow on the inner wall of the tapered section 211 to a certain extent, extending the service life of the micro / nano bubble generator 2.

[0102] It is understood that the cone angle α can be any integer value between 0° and 60°, such as 10°, 20°, 30°, 40°, 50°, 60°, etc.; or it can be any degree between two large integer degrees, such as any value between 0° and 10°, such as 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, etc.

[0103] The pore size of the throat 212 is D1, and 0.3mm≤D1≤3.0mm. This setting ensures that the water flow receives sufficient shear force when passing through the throat 212, promoting the effective release of micro- and nano-bubbles. At the same time, this pore size range also ensures the smoothness of the water flow through the throat 212, avoiding excessive resistance or blockage.

[0104] Specifically, the aperture D1 can be any integer value between 0.3 mm and 3.0 mm, such as 0.5 mm, 1.0 mm, 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm, etc.; or it can be any number of millimeters set between two large millimeter values, such as any value between 0.3 mm and 0.5 mm, such as 0.35 mm, 0.4 mm, 0.45 mm, etc. This setting allows the micro / nano bubble generator 2 to adapt to different application scenarios and needs.

[0105] The cone angle of the diffuser section 213 is β, where 2° < β ≤ 20°. This cone angle β ensures that the water flow diffuses smoothly when it leaves the throat 212 and enters the diffuser section 213, while avoiding excessive dynamic loss due to an excessively large diffusion angle. Specifically, the cone angle β can be any integer value between 2° and 20°, such as 3°, 5°, 7°, 10°, 15°, 20°, etc.; or it can be any value set between these large integer degrees, such as any value between 5° and 10°, such as 6°, 7.5°, 8.3°, etc. This cone angle design ensures smooth water diffusion and effectively controls dynamic loss, thereby improving the generation efficiency and quality of micro / nano bubbles.

[0106] In the technical solution of this utility model, the aperture of the water outlet 12 is also limited. In some embodiments, the aperture of the water outlet 12 is D2, and 0.3mm≤D2≤1.0mm. This setting ensures that the water outlet 12 can generate a sufficient number of micro-nano bubbles, while avoiding blockage or excessive water pressure caused by too small an aperture.

[0107] Specifically, the aperture D2 can be any value between 0.3 mm and 1.0 mm, such as 0.4 mm, 0.5 mm, 0.7 mm, 0.9 mm, etc.; or it can be any fine degree set between these specific values, such as 0.65 mm, 0.82 mm, etc. This aperture design improves the durability and practicality of the water outlet structure 100, thereby meeting the needs of different application scenarios.

[0108] Since all the dissolved air water exits through the flow channel 21, in order to reduce the probability of blockage of the flow channel 21, in some embodiments, a filter structure is provided in the water outlet body 1 to reduce the probability of blockage of the flow channel 21.

[0109] Specifically, when the water outlet body 1 is set as the shower head body 1a, a filter structure, such as a filter screen, can be installed on the shower head handle 3. This can effectively intercept larger impurity particles, preventing them from entering the flow channel 21 and reducing the risk of clogging. Furthermore, the filter screen is designed for easy disassembly and cleaning, allowing users to clean it regularly according to actual usage, ensuring the continuous and efficient operation of the water outlet structure.

[0110] Of course, a filter structure can also be installed on the water inlet pipe connected to the shower handle 3, all of which are within the protection scope of this utility model.

[0111] When the water outlet body 1 is set as a faucet body 1b, a filter structure can be set on the water inlet pipe connected to the faucet body 1b. All of the above are within the protection scope of this utility model.

[0112] This utility model also proposes a water outlet device, which includes a water outlet structure 100. The water outlet structure 100 adopts all the technical solutions of all the above embodiments, and therefore has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
