At present, in order to take into account the product performance of achieving two-speed switching, two-speed water discharge reliability and water spray effect, the overall structure of the bubbler tends to be complicated. The complexity is mainly reflected in the following two points: first, the number of parts for assembling the bubbler has increased; second, the structural modeling of each component and the assembly between the components are becoming more and more complicated. In this way, it is inevitable that the production will bring about a substantial increase in the cost of materials, manufacturing processes, assembly processes, etc. Therefore, it is difficult for the various bubbler structures currently available to take into account the problems of structural simplification, product performance and production costs.

[0008] Furthermore, the plurality of water guide holes and the plurality of isolation holes are evenly and alternately arranged on the same radial circumference.

[0009] Furthermore, the plurality of water guide holes are evenly arranged around the circumference, and the first water guide channel includes a plurality of water guide grooves formed between every two adjacent water guide holes; the plurality of water guide grooves and the plurality of isolation holes are arranged one-to-one in isolation from each other upstream and downstream in the axial direction of the water guide body.

[0010] Furthermore, an isolating slope is provided between the water diversion groove and the isolating hole for isolating the two, and the isolating slope is arranged obliquely from upstream to downstream toward the center.

[0011] Furthermore, the radial value of the water diversion hole is 1.5-5.5 times the radial value of the second air intake channel.

[0018] After adopting the above scheme, the new water outlet device has at least the following advantages compared with the prior art:

[0019] Beneficial effects:

[0020] 1. The new water outlet device includes three parts: a closing shell, a water diverter and a water guide. The water diverter is rotatably connected to the water guide, and the water guide is fixedly connected to the closing shell to achieve synchronous movement of the two during use. The design principle of the fixed connection is that the entire inner arc surface of the smooth shell remains in a smooth surface form without any processing, and the water guide is designed with a fixed section and the elasticity of the fixed section's own material is used to cooperate with the smooth surface of the smooth shell to achieve a stable fixed connection. The number of parts, structural modeling of parts, and matching connections between parts of the new device are extremely simplified, the production cost of parts is low, the assembly steps of parts are simplified, the degree of freedom is high during assembly, and there is no need to find the assembly alignment direction, which greatly improves the assembly efficiency and ultimately has an overall cost advantage.

[0021] Second, the novel water outlet device has an extremely simplified structure and cost advantages, and also has an excellent bubble water spray function. The device includes a first air suction channel and a second air suction channel, and the radial value of the second air suction channel is smaller than the radial value of the water diversion hole. When the water outlet is switched to the water diversion hole and connected to the first water guide channel to achieve bubble water outlet, under the condition limited by the radial value relationship, the first air suction channel and the second air suction channel form a double air suction channel to effectively exert a double negative pressure suction effect, and the oxygen content of the bubble water is greatly improved, and finally a softer and better water type bubble water outlet effect is obtained. According to Bernoulli's principle, in a water flow or air flow, if the speed is small, the pressure is large, and if the speed is large, the pressure is small. By controlling the gap of the second air suction channel to be smaller than the radial value of the water diversion hole of the water diversion body, it is ensured that the gas velocity of the second gap is always higher than the gas velocity around the water outlet channel, and a small amount of splashing water flowing out of the water outlet channel is brought back into the water outlet channel.

[0022] 3. When the water outlet is switched to the water diversion hole and connected to the first water guide channel to realize the bubble water outlet, in the double air inhalation channel, the first air inhalation channel is the main air inhalation channel, which constitutes the first line of defense for water diversion, and most of the splashed and scattered water droplets are pushed back to the first water guide channel by air pressure; the second air inhalation channel is the auxiliary air inhalation channel, which constitutes the second line of defense for water diversion, and the radial value of the second air inhalation channel is smaller than the radial value of the water diversion hole. The size association scheme is adopted. For the water diversion hole, its water outlet is large, ensuring that the water flow is divided into several strands and passes through quickly and timely. For the second air inhalation channel, the second air inhalation channel can form an effective wind pressure, and the negative pressure airflow is fast enough to cooperate with the first air inhalation channel to push all the small part of the splashed water droplets that may be missed back to the first water guide channel. Therefore, the new type adopts the double air inhalation channel scheme to achieve the ability to prevent the internal water flow from running, backflow, cross-flow and other problems on the basis of large water diversion flow, bringing the technical effect that there is no need to set a seal between the water diversion body and the water guide body to avoid the above problems, and at the same time achieves a reliable two-speed water outlet effect.

[0023] Fourth, the fixed section of the water guide body uses its own material elasticity to achieve fixed connection with the light shell, and the light shell has a continuous holding force on the fixed section. Furthermore, a number of isolation holes are provided between the first water guide channel and the outer wall in the fixed section of the novel water guide body, and the plurality of isolation holes are evenly distributed in a circular array to form an isolation ring. The fixed section is bounded by the isolation ring and has an isolation inner ring part and a stress outer ring part. The continuous holding force only acts on the stress outer ring part, and the isolation inner ring part is not subjected to force and remains deformed. The first water guide channel is correspondingly located in the isolation inner ring part, thereby avoiding the risk of water splash disorder or even water leakage caused by the deformation of the first water guide channel due to the holding force, ensuring that the device has a lasting and excellent bubble water splash water discharge effect, and improving the durability and service life of the product.

DETAILED DESCRIPTION

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0039] A water outlet device, such as Figure 1-12 As shown, it includes a bare shell 1, a water dividing body 2 and a water guiding body 3.

[0040] The water diverter 2 and the water guide 3 are rotatably connected to each other, and two-speed switching is performed by rotation to achieve different water discharge and water splash functions. The water diverter 2 is provided with a plurality of water diverter holes 21, and the water guide 3 is provided with a first water guide channel 31 and a second water guide channel 32. The water diverter 2 and the water guide 3 are rotated with each other to achieve two-speed water discharge switching, specifically, the water diverter hole 21 is connected to the first water guide channel 31 to achieve a bubble water discharge effect, or the water diverter hole 21 is connected to the second water guide channel 32 to achieve a shower water discharge effect.

[0041] The second water channel 32 is composed of a plurality of water holes 321. When the water outlet is switched to the state where the water diversion hole 21 is connected to the second water channel 32, as shown in FIG. Figure 4-5 As shown, a plurality of water diversion holes 21 and a plurality of water guide holes 321 are respectively arranged in a one-to-one correspondence, water flows in from the water diversion body 2, flows out through a plurality of water diversion holes 21, and then enters a plurality of water guide holes 321 in a one-to-one correspondence. The structural relationship between the water diversion holes 21 and the water guide holes 321 in the connected state is that the water flow cross section at the water outlet end of the water diversion hole 21 is projected within the water flow cross section at the water inlet end of the water guide hole 321 (see Figure 6 ).

[0042] When the water outlet is switched to the state where the water diversion hole 21 is connected to the first water guide channel 31, as shown in FIG. Figure 7-8 As shown, water flows into the water diversion body 2 of the device, flows out through a plurality of diversion holes 21, and then enters the first water guide channel 31. Figure 8 As shown, in the connected state, the second water channel 32 becomes the first air suction channel 41 which is in air pressure communication with the first water channel 31. There is a gap 411 between the upstream of the first air suction channel 41 and the bottom surface of the water diversion body 2 to achieve the air pressure communication between the first air suction channel 41 and the first water channel 31.

[0043] In the embodiment, the second water guide channel 32 is composed of a plurality of water guide holes 321, and the plurality of water guide holes 321 are evenly arranged on a circumference. A cavity is provided at the inner center of the water guide body 3 to form a first water guide channel 31, and the first water guide channel 31 includes a plurality of water guide grooves 311 formed between each two adjacent water guide holes 321. When the water outlet is switched to the water diversion hole 21 and connected with the water guide groove 311, the bubble water outlet effect is realized, and when the water outlet is switched to the water diversion hole 21 and connected with the water guide hole 321, the shower water outlet effect is realized.

[0044] like Figure 2 , Fig.12 As shown, the light shell 1 is a cylindrical structure, which has an inner arc surface 11, and the inner arc surface 11 of the light shell 1 is a smooth surface. The smooth surface here means that the inner arc surface 11 of the light shell 1 is not provided with any structure that affects the flatness of the arc surface. Here, the structure that affects the flatness of the arc surface includes a concave-convex structure, a groove structure, a step surface structure, etc.

[0045] like Figure 2 , Fig.12 As shown, the water guide body 3 has a fixed section 30, and the fixed section 30 of the water guide body 3 uses its own material elasticity to achieve a fixed connection with the light shell 1 so that the two maintain synchronous movement during use. The principle of the fixed connection here is that the inner arc surface of the light shell 1 with its smooth surface shape and the connection state of the fixed section 30 using its own material elasticity make the fixed connection between the water guide body 3 and the light shell 1 very stable and reliable, and the two always maintain synchronous movement.

[0046] like Figure 7 As shown, the outer diameter R1 of the fixing section 30 is larger than the outer diameter R2 of the water diversion body 2, so there is a gap between the outer wall of the water diversion body 2 and the inner wall of the light shell 1, as shown in FIG. Figure 8 As shown, the gap forms the second air suction channel 42. When the water outlet is switched to the state where the water diversion hole 21 is connected to the first water guide channel 31, the first air suction channel 41 is connected to the first water guide channel 31 by air pressure, and the second air suction channel 42 is connected to the first water guide channel 31 by air pressure. There is a ventilation gap between the water diversion body 2 and the water guide body 3 due to the non-airtight rotation connection, so that the second air suction channel 42 and the first water guide channel 31 are connected by air pressure.

[0047] There is a gap between the outer wall of the water-dividing body 2 and the inner wall of the light shell 1. In the manufacturing process, the gap cannot be too small. If it is designed to be too small, the light shell 1 may be prone to jamming during the rotation process relative to the water-dividing body 2 due to tolerance reasons after assembly, affecting the smoothness and practicality of the gear switching operation. In order to avoid this problem, the gap design does not have an upper limit, and it is as large as possible. The new invention innovatively forms the gap into a second air suction channel 42 with an air suction effect, and has special requirements for the upper limit of the radial value of the second air suction channel 42, specifically, the radial value L3 of the second air suction channel 42 is less than the radial value L1 of the water-dividing hole 21. In a preferred embodiment, L1 is between 1.5-5.5 times of L3. In this way, when the water is discharged when the water-dividing hole 21 is switched to the connected state with the first water-conducting channel 31, the gap can generate wind pressure and form a channel structure for negative pressure suction. The radial value refers to the length of the hole or gap in the corresponding radial reference direction.

[0048] When the water diversion hole 21 is connected to the first water guide channel 31, water flows out from the water diversion hole 21 quickly and forms a negative pressure around the injection. The outside air enters the waterway through the first air intake channel 41 to achieve air-water mixing. The outside air also enters the waterway through the connection gap between the water diversion body 2 and the water guide body 3. Due to the structural characteristics of the connection gap, the negative pressure air intake here is small, and the ejected water flow may have the problem of outflow and leakage. The new type aims at the gap between the outer wall of the water diversion body 2 and the inner wall of the light shell 1, and forms a narrow tube structure that is pulled by the negative pressure of the water diversion hole 21 to generate effective wind pressure through the radial relationship with the water diversion hole 21, that is, the second air intake channel 42. According to Bernoulli's principle, in water flow or air flow, if the speed is small, the pressure is large, and if the speed is large, the pressure is small. By controlling the gap of the second air intake channel to be smaller than the radial value of the water diversion hole of the water diversion body, a small radial value leads to an increase in flow velocity, ensuring that the gas velocity in the narrow tube channel is always higher than the gas velocity around the water outlet channel, and bringing a small amount of droplets gushing out of the water outlet channel back into the water outlet channel.

[0049] Furthermore, the radial value L3 of the second air intake channel 42 is smaller than the radial value L1 of the water diversion hole 21, and the area of ​​the minimum cross section of the second air intake channel 42 is greater than or equal to 1.2 times the total jet area of ​​all water diversion holes 21, and the total jet area of ​​all water diversion holes 21 is the sum of the jet cross-sectional areas of each water diversion hole 21. In this way, it is ensured that the gas flow rate of the narrow tube channel is increased and the gas volume is sufficient, and sufficient wind pressure and air volume are formed at the connection gap to further ensure that cross-flow and water leakage do not occur.

[0050] In this way, the novel water outlet device has the technical effects of extremely simplified structure, excellent product performance and cost advantage:

[0051] 1. The new water outlet device has excellent product performance. The device adopts dual air suction channels (first air suction channel 41 and second air suction channel 42). The dual air suction channels are matched inside and outside. The radial value L3 of the second air suction channel 42 is less than the radial value L1 of the water diversion hole 21. When the water outlet is switched to the state where the water diversion hole 21 is connected to the first water guide channel 31 to achieve bubble water outlet, under the condition of the radial value relationship, the first air suction channel 41 inside and the second air suction channel 42 in the outer circumferential direction play an effective double negative pressure suction effect. The dual air suction channels are matched inside and outside, and the jet wind pressure is fully used to constrain the water flow in a directional manner, and no additional seals or water retaining parts are required.

[0052] Second, the novel water outlet device can achieve the purpose of reliable two-speed water outlet function without setting a seal. When the water outlet is switched to the water diversion hole 21 and connected to the first water guide channel 31 to realize the bubble water outlet, the first air intake channel 41 in the double air intake channel is the main air intake channel, which constitutes the first line of defense for water diversion, and most of the splashed and scattered water droplets are pushed back to the first water guide channel by air pressure. The second air intake channel 42 is an auxiliary air intake channel, which constitutes the second line of defense for water diversion. The size association scheme that the radial value of the second air intake channel 42 is smaller than the radial value of the water diversion hole 21 is adopted. For the water diversion hole 21, its water outlet is large, ensuring that the water flow is divided into several streams and can pass quickly and timely; for the second air intake channel 42, the second air intake channel 42 can form an effective wind pressure, and the negative pressure airflow is fast enough, cooperating with the first air intake channel 41 to push all the small part of the splashed water droplets that may be missed back to the first water guide channel 31. Therefore, the present invention adopts a double air suction channel solution to achieve the ability to effectively prevent internal water flow from leaking, backflow, cross-flow and other problems on the basis of large water flow distribution, without the need for additional seals or water retaining parts, while achieving two-speed water outlet effects with reliable performance, which also benefits the simplification of the overall structure and assembly.

[0053] 3. The extremely simplified structure of the new water outlet device is reflected in the number of parts and the structure of the parts themselves. On the one hand, the main parts of the water outlet device only include the closing shell 1, the water diversion body 2 and the water guide body 3. The number of parts is extremely simplified. The parts that are assembled with each other exist between the smooth shell 1 and the water guide body 3, and between the water diversion body 2 and the water guide body 3. No seals are required between them. On the other hand, the closing shell 1 is a smooth shell with an extremely simple structural design. At the same time, the fixed connection structure with the fixed section 30 of the water guide body 3 also has extremely simple characteristics.

[0054] 4. The cost advantage of the new water outlet device is reflected in two aspects: manufacturing and component assembly. In manufacturing, the extremely simplified number of parts described in the new device can bring cost advantages of materials and production processes; the extremely simplified structure of the parts themselves simplifies the manufacturing process accordingly. In manufacturing, since each additional structural design point requires the addition of corresponding design tools and process steps, the cost is increased. The new light shell 1 is a smooth surface shape, and there is no need to design conventional structures such as concave and convex, keyways, steps, etc. to achieve assembly or positioning in different directions. The structure and process are greatly simplified, thereby greatly reducing the manufacturing cost. The extremely streamlined number of parts in this device also greatly simplifies the assembly steps, and the assembly freedom between the light shell 1 and the water guide body 3 is high during operation, and there is no need to find the direction of mutual alignment during the assembly process. This greatly improves the assembly efficiency and brings the advantage of low assembly cost.

[0055] Furthermore, if Figure 9-12 As shown, the fixed section 30 includes a connection end 301, a water outlet end 302 and an outer wall surface 303. The connection end 301 is the end position where the water guide body 3 and the water diversion body 2 are rotatably connected to each other, and the outer wall surface 303 is the contact surface where the fixed section 30 is fixedly connected to the light shell 1. A plurality of isolation holes 34 are evenly distributed in a circumferential array between the first water guide channel 31 and the outer wall surface 303 in the fixed section 30. The isolation holes 34 are opened from the water outlet end 302 of the fixed section 30 and extend in a non-through manner toward the connection end 301.

[0056] The fixed section 30 of the water-conducting body 3 is fixedly connected to the light shell 1 by utilizing the elasticity of its own material. The light shell 1 has a holding force that continuously squeezes the fixed section 30 inward. The corresponding first water-conducting channel 30 inside the fixed section 30 may be slightly deformed due to long-term squeezing. When the water flow reaches the slightly deformed surface, it will cause water splashes to scatter, become turbulent, or water to bubble up and cause leakage.

[0057] The present invention adopts such a scheme that a plurality of isolation holes 34 are provided between the first water guiding channel 31 and the outer wall surface 303. The plurality of isolation holes 34 are evenly distributed in a circular array, which is equivalent to forming an isolation ring. The fixed section 30 is formed with an isolation inner ring portion 35 and a stress outer ring portion 36 inside and outside the isolation ring as the boundary. At this time, the continuous holding force applied by the light shell 1 only acts on the stress outer ring portion 36. The isolation inner ring portion 35 maintains a stable structure without deformation because it is not subjected to force. The first water guiding channel 31 is correspondingly formed on the isolation inner ring portion 35, thereby avoiding the problem of deformation of the first water guiding channel 31 caused by the holding force, ensuring that the device has a lasting and excellent bubble water spray effect, and improving the durability and service life of the product.

[0058] Furthermore, if Fig.10As shown, the plurality of water guide holes 321 and the plurality of isolation holes 34 of the second water guide channel 32 are evenly arranged alternately on the same radial circumference. In a specific embodiment, the water guide holes 321 are circular holes, and the isolation holes 34 are elliptical holes with their major axes extending radially.

[0059] By adopting such a scheme, the structural design of the novel water outlet device is reasonable and compact, and the water guide body 3 does not need to make additional structural adjustments due to the isolation hole 34. In addition, the arrangement on the same radial circumference also ensures that the isolation inner ring part 35 and the stress outer ring part 36 separated by the isolation hole 34 are more clearly defined, and the isolation and deformation prevention effect of the first water guide channel 31 is better. The arrangement on the same radial circumference also well disperses the effect of the continuous holding force on the second water guide channel 32, ensuring that the second water guide channel 32 (i.e., the first air suction channel 41) has a stable structure, which is beneficial to the shower water outlet effect and the bubble water outlet effect.

[0060] The novel water outlet device is a small-sized water outlet accessory. In order to achieve good water outlet in both gears without affecting each other, requirements are put forward for the structural design of the internal water outlet channel or water outlet hole. Among them, the water flow area of ​​each gear needs to be reasonably allocated to ensure that the water flow can pass through in time in both gears. The hole structure should be arranged reasonably to balance the water flow rate and avoid the problem of water leakage. In the novel water outlet device, the water diversion hole 21 is designed with eight holes evenly distributed in a circular array, corresponding to eight water guide holes 321 and eight water diversion grooves 311. On this basis, eight isolation holes 34 are cleverly designed in the interval space formed by the structure of the water diversion groove 311 between each two adjacent water guide holes 321. This is the optimal combination layout of the water diversion hole 21, the water guide hole 321, the water diversion groove 311 and the isolation hole 34, which achieves the comprehensive effect of meeting the water flow rate, avoiding water leakage, good water splash and water shape, and appropriate and effective isolation to prevent deformation.

[0061] Furthermore, if Fig.11 As shown, the plurality of water guide holes 321 are evenly arranged around the circumference, and the first water guide channel 31 includes a plurality of water guide grooves 311 formed between each two adjacent water guide holes 321. The plurality of water guide grooves 311 and the plurality of isolation holes 34 are arranged one by one in an upstream and downstream manner in isolation from each other in the axial direction of the water guide body 3.

[0062] By adopting such a solution, the structural design inside the novel water guide body 3 is very reasonable and compact, and can well realize the two-speed switching function, while ensuring the functional effectiveness brought by the isolation hole 34.

[0063] Furthermore, if Fig.11 As shown, there is an isolating slope 351 between the water diversion groove 311 and the isolating hole 34 for isolating the two, and the isolating slope 351 is arranged obliquely from upstream to downstream toward the center.

[0064] With such a solution, the upper side of the isolation slope 351 is the water diversion surface of the first water diversion channel 31, and the use of the slope is conducive to the water flow guidance. The lower side of the isolation slope 351 is composed of the blind end surface of the isolation hole 34, and the blind end surface is also arranged with a slope, which is conducive to the corresponding water diversion section of the first water diversion channel 31 having a uniform and effective isolation and deformation prevention effect.

[0065] Furthermore, the hole structure of the water diversion hole 21 can be designed in a variety of ways, usually in a symmetrical structure along the radial direction of the water diversion body. Figure 3 In the first embodiment, the water diversion hole 21 is a rectangular hole with its long side radially arranged along the water diversion body 2, and the radial value L3 of the second air suction channel 42 is less than the length L1 of the rectangular hole. In the second embodiment, the water diversion hole 21 is an elliptical hole with its long axis radially arranged along the water diversion body 2, and the radial value L3 of the second air suction channel 42 is less than the long axis length of the elliptical hole. In the third embodiment, the water diversion hole 21 is a circular hole, and the radial value L3 of the second air suction channel 42 is less than the diameter of the circular hole.

[0066] Furthermore, the rigidity of the bare shell 1 is greater than the elasticity of the fixed section 30, so that the fixed section 30 of the water-conducting body 3 can be tightly fixedly connected with the bare shell 1 by utilizing its material elasticity, while the bare shell 1 maintains its original structure without deformation. The bare shell 1 and the water-conducting body 3 can be selected from materials according to the performance and actual practical needs. In a preferred embodiment, the bare shell 1 is made of metal and the water-conducting body 3 is made of plastic, which is conducive to achieving the fixed connection effect by utilizing the elasticity of the material and the stability and durability of the structure of the entire device after connection.

[0067] Furthermore, the water diversion body 2 and the water guide body 3 are rotatably connected to each other. In a specific implementation, the water guide body 3 has a connecting section 33, that is, a connecting section 33 is provided at the connecting end 301 of the fixed section 30, and the outer diameter of the connecting section 33 is smaller than the outer diameter of the fixed section 30. The specific rotatable connection method adopts a buckle and a slot matching method. In the embodiment, a buckle 331 is provided on the outer wall of the connecting section 33, and a slot 22 is provided on the water diversion body 2. The buckle 331 is assembled in the slot 22 and can be rotated back and forth in the slot 22 to realize the mutual rotation of the water diversion body 2 and the water guide body 3.

[0068] Furthermore, preferably, the connecting section 33 is assembled with the water diversion body 2 in an embedded manner, which is conducive to simplifying the structural design, and the part with a gap between the water diversion body 2 and the inner wall of the light shell 1 only corresponds to the outer wall of the water diversion body 2, which is conducive to forming the second air suction channel 42. At the same time, the embedded rotation of the connecting section makes the ventilation gap between the water diversion body 2 and the water guide body 3 rotate and connect, and the ventilation gap and the second air suction channel 42 have good overall air permeability, which is conducive to the negative pressure air suction effect of the second air suction channel 42.

[0069] Furthermore, the corresponding segment edge of the fixed segment 30 is formed as a chamfered edge 304, which is conducive to the fixed connection and assembly between the fixed segment 30 and the light shell 1. The fixed segment 30 has two segment edges at the corresponding two ends (connection end 301 and water outlet end 302), and the chamfered edge can be set on any one or both of them. In a preferred embodiment, the chamfered edge 304 is formed on the segment edge at the corresponding connection end 301.

[0070] With this solution, when assembling the device, the water diverter 2 and the water guide 3 are first rotated and connected to each other, and then the closing shell 1 is assembled. The water diverter 2 is first inserted into the smooth shell 1, and then force is applied in the direction in which the smooth shell 1 and the water guide 3 are fitted together, and the guiding effect of the chamfered edge 304 is utilized to achieve a simple assembly operation and a stable and reliable fixed connection between the smooth shell 1 and the water guide 3.

[0071] Furthermore, the water inlet end of the water diversion body 2 (upstream of the water diversion hole 21) can be provided with a filter panel 23 as needed to filter the water flow. Similarly, the water outlet end of the first water guide channel 31 of the water guide body 3 can be provided with a support rib 37 to form a bubble outlet mesh, which is conducive to the outlet of bubble water.

[0072] The above description is only the preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention shall fall within the scope of the claims of the present invention.
