Description

Technical Field

[0001] The present invention relates to the technical field of water outlet devices, and in particular to a water outlet device. Background Art

[0002] In order to create a fine, silky spray of water, existing water outlet devices use a water outlet cover made of soft rubber, stainless steel, or plastic with a small aperture. However, due to the small aperture of the water outlet hole, dirt can easily clog the water outlet hole after a period of use, necessitating the water outlet cover to be cleaned. Compared to water outlet covers made of stainless steel, plastic, etc., a water outlet cover made of soft rubber has a unique advantage in cleaning. By rubbing the water outlet cover, dirt in the water outlet hole can be removed without complicated steps. Therefore, a water outlet cover made of soft rubber is more convenient to use. However, due to the characteristics of the soft rubber water outlet cover, when the aperture of the water outlet hole is small, the water flow will generate a large pressure at the water inlet end of the soft rubber water outlet cover, causing the soft rubber water outlet cover to deform during use. This deformation can cause the water outlet angle of the water to change unexpectedly, making it easy for the water to splash onto the user or other places. Summary of the Invention

[0018] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:

[0019] The first technical solution is to set a gas-liquid mixing chamber in the body, and to set a plurality of water holes and a plurality of ventilation grooves at the same time. After the water flows through the water holes, it enters the gas-liquid mixing chamber and loses pressure. At this time, the negative pressure formed by the water flow will cause the air outside the body to be sucked into the gas-liquid mixing chamber through the ventilation grooves, and fully mix with the water flow to form bubble water, and the outlets of the water holes are all set in the ventilation grooves, which can make the air reach the outlet position of the water holes along the ventilation grooves after entering the ventilation grooves, and can ensure the air and water flow when the cross-sectional area of ​​the body itself is large. After being fully mixed, the bubble water formed will make the water flow smoother, reduce the impact force of the water flow on the soft rubber water outlet part of the water outlet cover, thereby reducing the deformation degree of the soft rubber water outlet part, and avoiding the water flow splashing outward due to deformation of the soft rubber water outlet part caused by excessive impact force; at the same time, multiple water holes and ventilation grooves are provided, which can disperse the water flow while ensuring the water flow rate. The ventilation grooves and water holes correspond to each other to avoid the air loss entering the gas-liquid mixing chamber, improve the mixing degree of air and water flow, and more effectively reduce the impact force of the bubble water formed.

[0020] The second technical solution is to provide one or more water hole outlets in each ventilation groove. After the air enters the gas-liquid mixing chamber, it will fill the entire cavity. The ventilation groove can guide the air to quickly reach the outlet position of the water hole, so that the water flow can be fully mixed with the air. This can effectively improve the utilization rate of the air entering the gas-liquid mixing chamber, and thus effectively improve the mixing degree of water flow and air.

[0021] The third technical solution is to set an air intake channel on the main body, and the air intake channel connects the outside of the main body with the ventilation groove in the gas-liquid mixing chamber, so that the ventilation groove can take in air from the outside of the main body; at the same time, the air intake channel is provided with a vertical first section and a horizontal second section. This is because the water outlet device adopts a soft rubber water outlet part, and the pressure in the gas-liquid mixing chamber is relatively large. The bent structure of the air intake channel can prevent water from flowing back from the gas-liquid mixing chamber into the air intake channel.

[0022] The fourth technical solution is to provide an overflow groove with an upward opening on the channel wall of the air inlet channel. The overflow groove can temporarily store water when water flows back into the air inlet channel to prevent the water from blocking the air inlet channel.

[0023] In the fifth technical solution, the main body is composed of a jet part and a rectifying part. The split design can facilitate the molding and assembly of the various components of the main body. At the same time, the space between the two forms a gas-liquid mixing chamber. A rectifying plate is also provided on the rectifying part, and a protrusion is provided on the rectifying plate. When the water flows through the water hole into the gas-liquid mixing chamber, it will hit the rectifying plate and contact the protrusion, so that the water flow is fully dispersed, enhancing the effect of gas-liquid mixing, and at the same time reducing the impact force of the water flow.

[0024] The sixth technical solution defines the structure of the rectifier plate. The arrangement of the first rib and the second rib can form an effective rectifier structure while forming the second water outlet, and can also ensure that there is a sufficient impact area between the water flow and the rectifier plate without hindering the flow of water. At the same time, it also defines the position of the protrusion. The water flow will first touch the protrusion and then dissipate after the first impact. After being dispersed, the water flow moves in all directions and touches the first rib and the second rib and dissipates again, thereby effectively improving the rectification and mitigating the effect of water flow impact.

[0025] The seventh technical solution stipulates that the second rib has a groove, and the water flow first hits the protrusion, then hits the higher surface of the first rib and the second rib, and finally hits the bottom of the groove. After multiple collapses, the atomization degree of the water flow is higher, which can effectively reduce the impact force of the water flow.

[0026] The eighth technical solution further provides a flow limiting member and a flow limiting rubber ring in the water outlet device. The flow limiting rubber ring is installed in the annular groove on the flow limiting member and forms a water flow gap with the side groove wall of the annular groove. The flow limiting rubber ring will be deformed under the action of water pressure. When the water pressure is large, the throttling rubber ring will be flattened, reducing the water flow area of ​​the water flow gap, and hindering the water flow from passing through the flow limiting member into the first water flow chamber. When the water pressure is small, the flow limiting rubber ring will restore the deformation, and the water flow area of ​​the water flow gap will be restored, so that sufficient water will flow into the first water flow chamber, thereby ensuring the stability of the water flow rate.

[0027] The ninth technical solution adds a filter to the water outlet device, which can filter out larger particles in the incoming water through the filter holes, avoid clogging of the water outlet holes on the soft rubber water outlet part, and at the same time slow down the impact of water flow.

[0028] The tenth technical solution is to provide a clearance groove on the soft rubber water outlet. The setting of the clearance groove enables the soft rubber water outlet to have sufficient deformation ability. When the soft rubber water outlet needs to be cleaned, the dirt in the water outlet hole can be removed by rubbing the soft rubber water outlet.

[0029] The eleventh technical solution stipulates that the water outlet cover also includes a connecting frame, and the soft rubber water outlet part can be fixedly connected to the main body through the connecting frame, which enhances the deformation resistance of the soft rubber water outlet part itself and facilitates the assembly of the water outlet cover.

[0030] The twelfth technical solution limits the aperture range of the water outlet holes on the soft rubber water outlet part. The water outlet holes within this range can form fine cotton and linen water outlet. At the same time, the water outlet holes are smaller than the existing water outlet holes. Only in the scenario of water outlet holes of this size, it is necessary to use multiple means to solve the problem of deformation of the soft rubber water outlet part caused by excessive back pressure caused by too small an aperture.

[0031] The thirteenth technical solution adds an outer shell to the water outlet device, and at the same time provides an air guide groove on the outer wall of the main body. The outer shell can facilitate the installation and use of the water outlet device and protect its internal structure. Since the outer shell blocks the radial air intake of the air inlet on the outer wall of the main body, an axially extending air guide groove is provided. The air guide channel formed by the air guide groove and the outer shell is used to send the air to the air inlet in the axial direction, thereby ensuring the air intake volume of the gas-liquid mixing chamber.

Obviously, the described embodiments are preferred embodiments of the present invention and should not be regarded as excluding other embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0044] In the claims, description and drawings of the present invention, unless otherwise clearly defined, the use of terms such as "first", "second" or "third" is for the purpose of distinguishing different objects rather than for describing a specific order.

[0045] In the claims, specification and the above-mentioned drawings of the present invention, unless otherwise expressly defined, directional words such as the terms "center", "transverse", "longitudinal", "horizontal", "vertical", "top", "bottom", "inside", "outside", "up", "down", "front", "back", "left", "right", "clockwise", "counterclockwise" and the like indicating directions or positional relationships are based on the directions and positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the specific scope of protection of the present invention.

[0046] In the claims, description and above-mentioned drawings of the present invention, unless otherwise expressly defined, the terms "fixed connection" or "fixed connection" should be understood in a broad sense, that is, any connection method without displacement relationship and relative rotation relationship between the two parties, that is, including non-detachable fixed connection, detachable fixed connection, integral connection and fixed connection through other devices or elements.

[0047] In the claims, description and drawings of the present invention, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0048] See also Figure 1 , Figure 1 The exploded view of the structure of a water outlet device provided by the present invention is shown, which mainly includes a filter element 10, a flow-limiting rubber ring 61, a flow-limiting element 20, a jet element 30, a rectifying element 40, a water outlet surface cover 50 and a housing 60.

[0049] The jet component 30 and the rectifying component 40 together form the body of the water outlet device, and a gas-liquid mixing chamber 73 is formed in the body through the cooperation of the jet component 30 and the rectifying component 40 .

[0050] Reference Figure 7The filter element 10 is a filter component made of plastic material, on which a plurality of filter holes 11 are densely distributed. A clamping head structure is provided at its outer edge for clamping and fixing with the jet element 30.

[0051] Reference Figure 1 and Figure 7 The flow-limiting member 20 is a plastic flow-limiting component, with an annular groove 22 disposed in the middle thereof along the circumference of the flow-limiting member 20, and a flow-limiting water hole 21 disposed at the bottom of the annular groove 22. The flow-limiting rubber ring 61 is a rubber ring with a certain degree of deformability. Its inner diameter is roughly adapted to the inner diameter of the annular groove 22, allowing it to fit neatly within the annular groove 22. Furthermore, the width of the flow-limiting rubber ring 61 is smaller than that of the annular groove 22, forming a water-passing gap between the flow-limiting rubber ring 61 and the outer wall of the annular groove 22, through which water can flow to the flow-limiting water hole 21.

[0052] The filter element 10 is located above the flow-limiting element 20, and a second water flow chamber 71 is formed between the filter element 10 and the flow-limiting element 20. After passing through the filter hole 11 on the filter element 10, the water flows into the second water flow chamber 71. When the water flow pressure is large, the water pressure will cause the flow-limiting rubber ring 61 to deform, and cooperate with the uniformly distributed ribs on the groove wall on the outer side of the annular groove 22 to reduce the water flow area of ​​the water gap between the flow-limiting rubber ring 61 and the groove wall of the annular groove 22, thereby reducing the water flow rate flowing to the flow-limiting water hole 21. When the water pressure is small, the flow-limiting rubber ring 61 restores its deformation, and the water flow area of ​​the water gap is restored, so that the water flow can smoothly reach the flow-limiting water hole 21. Through the deformation and restoration of the flow-limiting rubber ring 61, the water flow rate at the flow-limiting water hole 21 can be kept stable.

[0053] Reference Figure 4 、 Figure 5 and Figure 7 ,in Figure 4 、 Figure 5 The bottom view of the jet element 30. The main body of the jet element 30 is a plate-shaped member, and an annular side wall is formed on the periphery of the plate-shaped member. The annular side wall extends to both sides of the plate-shaped member and surrounds the plate-shaped member. Figure 7From the perspective shown, the bottom wall of the plate-like component forms the top wall of the gas-liquid mixing chamber 73, on which a plurality of water holes 32 are provided. The inlet of the water hole 32 is located on the top surface of the plate-like component, and the outlet is located on the bottom surface of the plate-like component, that is, the outlet is located on the top wall of the gas-liquid mixing chamber 73. In addition, a ventilation groove 36 is also provided on the bottom surface of the plate-like component. The ventilation groove 36 extends along the radial direction of the plate-like component, and one end of the ventilation groove 36 is connected to the outer edge of the plate-like component, and the other end points to the center of the plate-like component. Two outlets of the water holes 32 are provided at the bottom of each ventilation groove 36, and the outlets of the two water holes 32 are arranged along the extension direction of the ventilation groove 36. The outlet of one water hole 32 is located in the middle of the ventilation groove 36, and the outlet of the other water hole 32 is located at the end of the ventilation groove 36 away from its air inlet end. The inlet diameter of the water hole 32 is larger than the outlet diameter, forming a trumpet-shaped structure, which accelerates the water flow when passing through the water hole 32 and diffuses outward after entering the gas-liquid mixing chamber 73 to form a negative pressure.

[0054] The plate-like component is further provided with positioning posts 311 . The positioning posts 311 extend toward the gas-liquid mixing chamber 73 , and four positioning posts 311 are evenly distributed on the top wall of the gas-liquid mixing chamber 73 .

[0055] The annular side wall is provided with a first clamping groove 31 extending along the circumferential direction on its inner wall surface. The first clamping groove 31 can cooperate with the fairing member 40 to form a clamping fixation.

[0056] An air inlet channel 35 is also provided within the annular sidewall. The air inlet channel 35 is divided into a first section 351 and a second section 352. The first section 351 extends parallel to the axial direction of the body, while the second section 352 extends perpendicular to the axial direction. One end of the first section 351 communicates with one end of the venting groove 36, while one end of the second section 352 communicates with the air inlet port 33 formed on the outer surface of the annular sidewall. The first section 351 and the second section 352 cooperate to form a curved air inlet structure, which prevents water in the gas-liquid mixing chamber 73 from flowing back into the air inlet channel 35. Specifically, in this embodiment, the first section 351 of the air inlet channel 35 begins at its connection with the venting groove 36 and extends upward from the jet element 30. Upon reaching a certain position, it connects with the second section 352 of the air inlet channel 35, thereby forming an upwardly curved structure for the air inlet channel 35 as a whole.

[0057] In particular, the first section 351 of the air inlet channel 35 is a groove-shaped structure, which is arranged along the circumference of the jet component 30, and is provided with multiple air inlet ends on the circumference of the jet component 30. The side walls of the first section 351 of each air inlet channel 35 form corresponding multiple ventilation grooves 36.

[0058] An overflow groove 34 is also provided on the second section 352 of the air intake channel 35. The overflow groove 34 is provided on the channel wall of the air intake channel 35 and opens vertically upward. It can form a temporary water storage structure when only a small amount of water flows back into the air intake channel 35 to prevent it from overflowing and causing water leakage.

[0059] In addition, refer to Figure 8 On the outer wall of the above-mentioned annular side wall, an air guide groove 37 extending along the axial direction of the jet component 30 is provided at the position corresponding to the air inlet 33. When the outer shell 60 is provided on the outside of the water outlet device provided in this embodiment, the air intake of the air inlet 33 in the radial direction will be blocked. At this time, the air guide groove 37 can cooperate with the shell 60 to form an air guide channel. One end of this air guide channel is connected to the second section 352 of the air inlet channel 35, and the other end is connected to the atmosphere, so that the air can be guided from the bottom of the water outlet device from bottom to top to the position of the air inlet 33, ensuring sufficient air intake. At the same time, it cooperates with the air inlet channel 35 inside the jet component 30 to form a "U"-shaped air intake passage, thereby effectively preventing water from flowing back from the gas-liquid mixing chamber 73.

[0060] A flow restrictor 20 is mounted above the jet element 30, forming a first water passage chamber 72 between the flow restrictor 20 and the jet element 30. After the water flows through the flow restrictor 20, it enters the first water passage chamber 72 and then enters the gas-liquid mixing chamber 73 through the water passage hole 32. After the water flows through the water passage hole 32 and enters the gas-liquid mixing chamber 73, negative pressure is generated, allowing air to enter the ventilation groove 36 through the air inlet channel 35, where it mixes with the water to form bubble water.

[0061] Reference Figure 3 、 Figure 7 The rectifying member 40 has a rectifying plate, and a circle of side walls is provided on the outer periphery of the rectifying plate. Figure 7 For example, the rectifying member 40 is located below the jetting member 30. A positioning groove 41 corresponding to the positioning post 311 on the jetting member 30 is provided on the inner sidewall of the rectifying member 40. A first clip 42 corresponding to the first clip 31 on the jetting member 30 is provided on the outer sidewall of the rectifying member 40. The first clip 42 is a raised structure extending along the circumference of the rectifying member 40. The plug-in fit between the positioning groove 41 and the positioning post 311, and the snap fit between the first clip 31 and the first clip 42, allows the rectifying member 40 and the jetting member 30 to be fixedly connected as one, forming a gas-liquid mixing chamber 73 therebetween. The rectifying plate forms the bottom wall of the gas-liquid mixing chamber 73. A plurality of second clips 43 are also provided on the outer sidewall of the rectifying member 40 for snap fit with the water outlet cover 50.

[0062] The rectifier plate is formed by staggering a plurality of first ribs 44 and a plurality of second ribs 45. The first ribs 44 are annular ribs arranged in a concentric annular pattern, while the second ribs 45 are linear ribs extending radially from the first ribs 44. Furthermore, the second ribs 45 are arranged circumferentially, forming a staggered arrangement. A through hole is formed between the first and second ribs 44, 45. This through hole serves as a rectifier water hole 47 that communicates with the gas-liquid mixing chamber 73. Specifically, a protrusion 46 is provided on the second rib 45 at the location corresponding to the intersection with the first rib 44. The protrusion 46 extends toward the top wall of the gas-liquid mixing chamber 73, and its free end has a spherical surface. This allows the water flow to disperse in all directions after impacting the protrusion 46. In addition, a groove 451 is provided on the second rib 45. The groove 451 is formed by a depression on the side surface of the second rib 45 facing the gas-liquid mixing chamber 73, and the bottom of the groove 451 is lower than the side surface of the first rib 44 facing the gas-liquid mixing chamber 73. At the same time, the position where the groove 451 is formed is located between two adjacent first ribs 44, so that the side surface of the second rib 45 facing the gas-liquid mixing chamber 73 is wavy, which can make the water flow more fully dispersed.

[0063] It should be noted that, since the second ribs 45 may interfere with each other when extending to the center of the rectifier plate, and also for the convenience of molding, only part of the second ribs 45 extend from the inner wall surface of the side wall of the rectifier 40 to the center of the rectifier plate, thereby forming a larger rectifier water hole 47 on the rectifier plate to ensure that the water flow will not accumulate too much in the gas-liquid mixing chamber 73.

[0064] Reference Figure 2 and Figure 7 The water outlet cover 50 is formed by a connecting frame 52 and a soft rubber water outlet portion 53. Specifically, the soft rubber water outlet portion 53 is a water outlet panel made of silicone material, which is provided with a plurality of water outlet holes 51. The connecting frame 52 is made of plastic, and the two are fixed to each other through secondary injection molding. A second slot 521 is provided on the connecting frame 52, which corresponds to the second clip 43 on the rectifier 40. The second clip 43 and the second slot 521 are engaged with each other to secure the water outlet cover 50 to the rectifier 40. A water outlet cavity 74 is also formed between the water outlet cover 50 and the rectifier 40. The rectifier water hole 47 guides the bubble water in the gas-liquid mixing chamber 73 into the water outlet cavity 74, and then discharges it outward through the water outlet hole 51. It should be noted that the connecting frame 52 is integrally covered at the lower position of the rectifying component 40, and the rectifying water hole 47 of the rectifying component 40 is only connected to the water outlet cavity 74, and the water outlet hole 51 is also only connected to the water outlet cavity 74, which makes the rectifying component 40 only able to discharge water through the water outlet hole 51.

[0065] In addition, refer to Figure 6On the lower surface of the soft rubber water outlet 53, that is, the surface of the side of the soft rubber water outlet 53 facing away from the water outlet cavity 74, a plurality of clearance grooves 54 are provided. The clearance grooves 54 are formed by the surface of the soft rubber water outlet 53 being concave toward the water outlet cavity 74. Since the soft rubber water outlet 53 itself has certain deformation characteristics, with the help of the clearance grooves 54, the soft rubber water outlet 53 can be cleaned by rubbing it.

[0066] During assembly, first, the jet component 30 and the rectifying component 40 are fixed together, then the surface cover 50 is installed, then the flow limiting component 20 is installed, then the flow limiting rubber ring 61 is put on the flow limiting component 20, and then the filter component 10 is installed.

[0067] Furthermore, in another embodiment, a housing 60 is further fixedly attached to the aforementioned water outlet device. This housing 60 may be provided with external threads for mating with a faucet, etc. In this case, the water outlet cover 50 may be entirely composed of a soft rubber outlet portion 53. The soft rubber outlet portion 53 and the housing 60 are fixedly attached to each other through secondary injection molding. When the housing 60 is fixedly attached to the rectifier 40 or the flow restrictor 20, the top surface of the soft rubber outlet portion 53 abuts against the bottom surface of the rectifier 40, forming a corresponding water outlet cavity 74.

[0068] In addition, in another embodiment, a shell 60 fixedly connected to the rectifier 40 can be provided, and a plurality of ribs are provided at the bottom of the shell 60. At the same time, a plurality of grooves adapted to the ribs are provided on the soft glue water outlet 53, and the soft glue water outlet 53 is partially exposed at the bottom of the shell 60. At this time, the soft glue water outlet 53 can be installed downward from the inside of the shell 60, so that the soft glue water outlet 53 is fixed on the shell 60, and then the rectifier 40 is installed into the shell 60 and abuts against the top surface of the soft glue water outlet 53 to form a corresponding water outlet cavity 74.

[0069] It should be noted that the soft rubber water outlet 53 in this embodiment has a large radial dimension, which requires that the water outlet device needs to use multiple means to slow down the impact of the water flow on the soft rubber water outlet 53, thereby avoiding large deformation of the soft rubber water outlet 53.

[0070] In the water outlet device provided in this embodiment, the incoming water flow first passes through the filter element 10, filters out large-sized particles, and then enters the second water flow chamber 71. Through the flow limiting effect of the flow limiting rubber ring 61 and the flow limiting element 20, a small part of the water flow passes through the flow limiting water hole 21 and enters the first water flow chamber 72, and then enters the water flow hole 32 in branches. Due to the structural characteristics of the water flow hole 32 itself, the water flow will form a negative pressure after entering the gas-liquid mixing chamber 73. The water flow inhales air through the ventilation groove 36 and the air inlet channel 35 to form bubble water. The water flow is weakened after inhalation and hits the rectifying plate of the rectifying element 40, and then collapses and slows down again. After that, it loses most of its impact after passing through the rectifying water hole 47 to reach the water outlet chamber 74, and then passes through the water outlet hole 51 on the soft rubber water outlet part 53 to form water, thereby achieving the effect of reducing the deformation degree of the soft rubber water outlet part 53.

Modifications, equivalent substitutions, or other improvements to the embodiments of the present invention or portions thereof that can be obtained by a person of ordinary skill in the art through logical analysis, reasoning, or limited experimentation based on the teachings of the present invention or the above embodiments, combined with common knowledge, ordinary technical knowledge in the field, and / or prior art, should all be included within the scope of protection of the present invention.
