Description

Technical Field

[0001] This invention relates to the field of drinking water equipment technology, specifically providing a water outlet assembly and a drinking water device including the water outlet assembly. Background Technology

[0002] Water supply equipment includes pipeline water dispensers, water purifiers, and integrated water purification and heating systems. Taking instant hot pipeline water dispensers and integrated water purification and heating systems as examples, most existing instant hot pipeline water dispensers and integrated water purification and heating systems use quartz tube electric heating film or thick film heating elements, providing instant hot water and convenient use, which is very popular among users.

[0003] However, since instant water dispensers and integrated water purifiers and heat pumps mostly use tankless rapid heating technology, in actual operation, purified water is pumped into the rapid heating pipe and quickly heated to boiling before being discharged from the water tap. The vent of the existing water tap is located near the water outlet, and what is discharged from the vent is high-temperature water vapor separated in the water vapor separator. This can easily cause burns from the high-temperature water vapor, posing a certain safety hazard and seriously affecting the user experience. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem that existing water dispensers have a poor user experience due to the risk of users being scalded by high-temperature water vapor when dispensing hot water.

[0005] In a first aspect, the present invention provides a water outlet assembly having an inlet and an outlet. The water outlet assembly includes a jetting member and a flow guiding member. The flow guiding member has a flow guiding cavity. The inlet is disposed on the jetting member. A first end of the flow guiding cavity is connected to the jetting member. The jetting member is configured to jet a high-speed hot fluid toward the flow guiding cavity. A second end of the flow guiding cavity is connected to the outlet so that the hot fluid in the flow guiding cavity flows out from the outlet. The flow guiding member is configured to introduce external airflow into the flow guiding cavity so that the high-temperature vapor in the flow guiding cavity condenses.

[0006] In the preferred embodiment of the above-mentioned water outlet assembly, the flow guiding member includes a flow guiding tube, the flow guiding cavity is formed inside the flow guiding tube, the first end of the flow guiding tube is connected to the spraying member, the second end of the flow guiding tube is connected to the water outlet, and a first air inlet is provided on the first end of the flow guiding tube and / or the side wall of the flow guiding tube, so that external airflow can enter the flow guiding cavity through the first air inlet.

[0007] In the preferred embodiment of the above-mentioned water outlet assembly, the flow guiding component further includes an end cap, which is disposed at the first end of the flow guiding pipe. The end cap and the flow guiding pipe together form the flow guiding cavity, and the first air inlet is disposed on the end cap.

[0008] In the preferred embodiment of the above-mentioned water outlet assembly, the guide pipe includes a first pipe body and a second pipe body connected together. The first end of the first pipe body is connected to the spray member, the second end of the first pipe body is connected to the first end of the second pipe body, and the second end of the second pipe body is connected to the water outlet. The cross-sectional area of ​​the first pipe body gradually decreases along the direction close to the water outlet, and the cross-sectional area of ​​the second pipe body gradually increases along the direction close to the water outlet.

[0009] In the preferred embodiment of the above-mentioned water outlet assembly, the spraying component includes a connected spray pipe and a spray head. The water inlet is disposed on the spray pipe, and the spray head is provided with spray holes. When installed, the spray head is located in the flow guiding cavity so that hot water entering the spray pipe from the water inlet is sprayed into the flow guiding cavity through the spray holes.

[0010] In the preferred embodiment of the above-mentioned nozzle assembly, the spray member is provided with a first mounting structure, and the end cap is provided with a second mounting structure. When installed, the first mounting structure and the second mounting structure cooperate to install the spray member on the guide member.

[0011] In the preferred embodiment of the above-mentioned water outlet assembly, the water outlet assembly further includes a flow stabilizing member disposed on the flow guiding member. One end of the flow stabilizing member is connected to the second end of the flow guiding cavity, and the other end of the flow stabilizing member forms the water outlet. The flow stabilizing member is configured to enable the water in the flow guiding cavity to flow smoothly out of the water outlet.

[0012] In the preferred embodiment of the above-mentioned water outlet assembly, the flow stabilizing component includes a housing and a first mesh and a second mesh disposed within the housing. The first mesh is provided with a plurality of water inlet holes, which are connected to the flow guiding cavity. The water outlet is formed on the second mesh. The first mesh is curved and extends toward the side away from the water outlet.

[0013] In the preferred embodiment of the above-mentioned water outlet assembly, the flow stabilizing component further includes a third mesh body disposed within the housing. The third mesh body is located between the first mesh body and the second mesh body. The third mesh body is provided with a water passage hole. The housing is provided with a second air inlet, which is located between the second mesh body and the third mesh body, so as to introduce external airflow into the housing to reduce the flow rate of water flowing out from the water passage hole.

[0014] In a second aspect, the present invention provides a drinking water device, the drinking water device including the water outlet assembly described above.

[0015] When the above technical solution is adopted, by setting up a jetting component and a flow guiding component, when the jetting component sprays high-speed hot fluid toward the flow guiding cavity, the high-speed jet can generate negative pressure in the flow guiding cavity, thereby facilitating the introduction of external airflow into the flow guiding cavity. The external airflow causes the high-temperature water vapor in the flow guiding cavity to condense, and the high-temperature water vapor condenses into water droplets and flows out from the outlet with the hot fluid, thereby preventing users from being scalded by high-temperature water vapor and greatly improving the user experience.

[0016] Furthermore, compared to setting the flow guide component in the form of a flow guide box, setting the flow guide component in the form of a flow guide pipe can make the flow guide component smaller, reduce the installation space of the water outlet assembly, and further improve the user experience.

[0017] Furthermore, compared to placing the first air inlet on the side wall of the guide pipe, placing the first air inlet at the first end of the guide pipe can prevent hot water inside the guide pipe from splashing out from the first air inlet, further improving the user experience.

[0018] Furthermore, by configuring the guide pipe as a first pipe body and a second pipe body, the hot fluid ejected by the spraying component can first pass through the first pipe body for further depressurization and acceleration. On the one hand, this helps to create a negative pressure in the first pipe body, making it easier to introduce external cold air into the guide cavity. On the other hand, it promotes gas-liquid separation of the hot fluid in the first pipe body, causing water vapor to rise and condense when it meets the cold air introduced from the first air inlet, preventing high-temperature water vapor from being directly discharged and scalding the user. Then, the hot fluid flowing out of the first pipe body flows into the second pipe body and has its flow rate reduced in the second pipe body, making it easier for the water in the guide cavity to flow out of the second pipe body more smoothly, preventing water splashing and swaying, and further improving the user experience.

[0019] Furthermore, compared to setting the spraying component in the form of a high-pressure spray gun, setting the spraying component in the form of a spray pipe and nozzle can reduce the cost of the spraying component, thereby reducing the cost of the water outlet assembly and further improving the user experience.

[0020] Furthermore, by setting a first mounting structure on the spray pipe and a second mounting structure on the end cap, it is easy to install the spray component on the guide component, thereby facilitating the assembly and disassembly of the water outlet assembly, and making it easier to replace and clean the parts of the water outlet assembly, further improving the user experience.

[0021] Furthermore, by setting up a flow stabilizing component, the water flowing out of the guide cavity can be buffered, making its flow rate more uniform and gentle, avoiding splashing and swaying when the water flows out of the outlet, thereby improving the water output effect of the water outlet assembly.

[0022] Furthermore, by configuring the flow stabilizing component to include a housing and a first mesh and a second mesh arranged sequentially within the housing, when the water in the guiding cavity reaches the first mesh, the water flow can be further slowed down and homogenized. After being filtered through the inlet mesh on the first mesh, the water is divided into multiple fine streams, and the flow rate of each fine stream tends to be consistent, forming a vertical, gentle, non-splashing water column that flows out from the outlet, further improving the water output effect.

[0023] Furthermore, by setting a second air inlet on the shell, the air entering the shell through the second air inlet can further buffer the water flow, thereby reducing the impact force of the water flow flowing out of the third mesh, resulting in a lower flow velocity and better water output.

[0024] Furthermore, the drinking device provided by the present invention, based on the above technical solution, includes the water outlet assembly described above, and thus possesses the beneficial effects of the water outlet assembly. Compared with the drinking device before the improvement, the drinking device of the present invention has a gentler water flow and a better water flow effect. When hot water is dispensed, the user is less likely to be scalded, and the user experience is better. Attached Figure Description

[0035] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0036] It should be noted that in the description of this invention, terms such as "upper," "inner," and "outer," which indicate direction or positional relationship, are based on the direction or positional relationship shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly, for example, referring to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] In light of the problem mentioned in the background art that existing water dispensers can easily scald users when dispensing hot water, resulting in a poor user experience, this invention provides a water outlet assembly. The water outlet assembly includes a jetting component and a flow guiding component. The flow guiding component has a flow guiding cavity, and the jetting component can jet a high-speed hot fluid into the flow guiding cavity. The flow guiding component is configured to introduce external airflow into the flow guiding cavity, so that the high-temperature water vapor in the flow guiding cavity will condense, preventing users from being scalded and greatly improving the user experience.

[0039] Specifically, please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of the water outlet assembly of the present invention. Figure 1 , Figure 2 This is a schematic diagram of the structure of the water outlet assembly of the present invention. Figure 2 , Figure 3 yes Figure 2 A schematic diagram of the cross-sectional structure along line AA.

[0040] like Figures 1 to 3 As shown, the water outlet assembly of the present invention has a water inlet 111 and a water outlet 331. The water outlet assembly includes a spray member 1 and a flow guide member 2. The flow guide member 2 has a flow guide cavity 20, and the water inlet 111 is disposed on the spray member 1.

[0041] The first end of the guide cavity 20 is connected to the injection component 1, which is configured to inject high-speed hot fluid toward the guide cavity 20. The second end of the guide cavity 20 is connected to the outlet 331 so that the hot fluid in the guide cavity 20 flows out from the outlet 331.

[0042] The flow guide member 2 is configured to introduce external airflow into the flow guide cavity 20 so that the high-temperature vapor in the flow guide cavity 20 will condense.

[0043] With this configuration, namely by setting up the jetting component 1 and the flow guiding component 2, when the jetting component 1 sprays high-speed hot fluid toward the flow guiding cavity 20, the high-speed jet can generate negative pressure in the flow guiding cavity 20, thereby facilitating the introduction of external airflow into the flow guiding cavity 20. The external airflow causes the high-temperature water vapor in the flow guiding cavity 20 to condense, and the high-temperature water vapor condenses into water droplets and flows out from the outlet 331 along with the hot fluid. This can prevent users from being scalded by high-temperature water vapor and greatly improve the user experience.

[0044] It should be noted that, in practical applications, the water outlet assembly of the present invention can be applied to water dispensers, water purifiers, or water purifier-water purifiers, with the hot fluid being hot water. Alternatively, the water outlet assembly of the present invention can also be applied to coffee machines, tea makers, and other equipment, with the hot fluid being hot coffee or hot tea or other hot beverages. Furthermore, the water outlet assembly can be applied to any other possible equipment, etc. Such adjustments and changes to the specific application equipment of the water outlet do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0045] The following describes in detail a specific embodiment of the water outlet assembly of the present invention, taking the application of the water outlet assembly on a pipeline machine as an example.

[0046] It should be noted that, in practical applications, those skilled in the art can configure the flow guiding member 2 as a flow guiding pipe 21, with a flow guiding cavity 20 formed inside the flow guiding pipe 21; or, the flow guiding member 2 can be configured as a flow guiding box, with a flow guiding cavity 20 formed inside the flow guiding box; or, the flow guiding cavity 20 can be configured as a fluid channel opened inside the flow guiding member 2, etc. Such adjustments and changes to the specific configuration type of the flow guiding member 2 do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0047] Preferably, such as Figures 1 to 3 As shown, the flow guiding component 2 includes a flow guiding pipe 21, and a flow guiding cavity 20 is formed inside the flow guiding pipe 21. The first end of the flow guiding pipe 21 is connected to the jetting component 1, and the second end of the flow guiding pipe 21 is connected to the water outlet 331. A first air inlet 221 connected to the flow guiding cavity 20 is provided on the first end of the flow guiding pipe 21 and / or on the side wall of the flow guiding pipe 21. External airflow can enter the flow guiding cavity 20 through the first air inlet 221.

[0048] By setting the flow guide component 2 as a flow guide pipe 21, compared to setting it as a flow guide box, the flow guide component 2 can be made smaller, reducing the installation space of the water outlet assembly and further improving the user experience.

[0049] In one specific embodiment, such as Figure 1 As shown, an end cap 22 is provided at the first end of the guide pipe 21, and a first air inlet 221 communicating with the guide cavity 20 is provided on the end cap 22. When the injection component 1 injects high-speed fluid toward the guide cavity 20, a negative pressure is formed in the guide cavity 20, thereby introducing the external airflow into the guide cavity 20 through the first air inlet 221, causing the high-temperature water vapor in the guide cavity 20 to condense.

[0050] In another specific embodiment, a first air inlet (not shown in the figure) is provided on the side wall of the guide pipe 21 to communicate with the guide cavity 20. When the injection member 1 sprays high-speed fluid toward the guide cavity 20, a negative pressure is formed in the guide cavity 20, thereby introducing the external airflow into the guide cavity 20 through the first air inlet 221, causing the high-temperature water vapor in the guide cavity 20 to condense.

[0051] In another specific embodiment, an end cap 22 is provided at the first end of the guide pipe 21, and a first air inlet 221 (not shown in the figure) communicating with the guide cavity 20 is provided on the side wall of the end cap 22 and the guide pipe 21. When the injection member 1 injects high-speed fluid toward the guide cavity 20, a negative pressure is formed in the guide cavity 20, thereby introducing the external airflow into the guide cavity 20 through the first air inlet 221, causing the high-temperature water vapor in the guide cavity 20 to condense.

[0052] It should be noted that the present invention does not impose any restrictions on the specific location of the first air inlet 221 on the guide pipe 21, as long as it can enable the external airflow to be introduced into the guide cavity 20 through the first air inlet 221 when the injection component 1 sprays high-speed fluid toward the guide cavity 20. Such adjustments and changes to the specific location of the first air inlet 221 on the guide pipe 21 do not deviate from the principle and scope of the present invention, and should be included within the protection scope of the present invention.

[0053] Preferably, such as Figure 1 As shown, the flow guiding component 2 of the present invention also includes an end cap 22, which is disposed at the first end of the flow guiding pipe 21. The end cap 22 and the flow guiding pipe 21 together form a flow guiding cavity 20, and the first air inlet 221 is disposed on the end cap 22.

[0054] By setting the first air inlet 221 at the first end of the guide pipe 21, compared to setting the first air inlet 221 on the side wall of the guide pipe 21, this arrangement can prevent hot water in the guide pipe 21 from splashing out from the first air inlet 221, thus further improving the user experience.

[0055] It should be noted that, in practical applications, those skilled in the art can configure the end cap 22 to snap onto the guide tube 21, or the end cap 22 can be fixedly connected to the guide tube 21 by fasteners, or the end cap 22 can be integrally formed with the guide tube 21, etc. Such adjustments and changes to the specific connection method between the end cap 22 and the guide tube 21 do not deviate from the principles and scope of the present invention, and should all be included within the protection scope of the present invention.

[0056] Preferably, the end cap 22 and the guide tube 21 of the present invention are integrally formed.

[0057] It should be noted that, in practical applications, those skilled in the art can set the number of first air inlets 221 to one, or the number of first air inlets 221 to multiple, etc. Such adjustments and changes to the specific number of first air inlets 221 do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0058] Preferably, such as Figure 1 As shown, there are multiple first air inlets 221, which are distributed at intervals along the horizontal direction on the end cap 22.

[0059] For example, such as Figure 1 As shown, there are 3 first air inlets 221.

[0060] With this configuration, compared to setting only one first air inlet 221, setting multiple first air inlets 221 with the multiple first air inlets 221 spaced apart in the horizontal direction on the end cover 22 can, on the one hand, increase the air intake volume, thereby enabling the high-temperature water vapor in the guide tube 21 to condense more quickly, thus better preventing users from being scalded by high-temperature steam; on the other hand, it can make the air intake more uniform and the air intake effect better.

[0061] It should be noted that, in practical applications, those skilled in the art can set the guide pipe 21 as a straight pipe, or it can set the guide pipe 21 as a variable diameter pipe, etc. Such adjustments and changes to the specific configuration type of the guide pipe 21 do not deviate from the principle and scope of the present invention, and should all be included within the protection scope of the present invention.

[0062] The following describes in detail the specific embodiments of the guide tube 21 of the present invention with reference to the following three embodiments.

[0063] Example 1:

[0064] The guide tube 21 of the present invention is a straight tube, that is, the inner diameter of the guide tube 21 is the same at all points.

[0065] Example 2:

[0066] The guide pipe 21 of the present invention is a variable diameter pipe, that is, the cross-sectional area of ​​the guide pipe 21 gradually decreases along the direction close to the outlet 331.

[0067] With this configuration, the hot fluid injected into the guide cavity 20 can have its flow rate further increased in the guide tube 21. Since the density of water vapor is less than that of boiling water, it can promote gas-liquid separation of the hot fluid in the guide tube 21. The water vapor rises and condenses when it meets the cold air introduced from the first air inlet 221, thus preventing the water vapor from being directly discharged at high temperature and scalding the user.

[0068] Example 3:

[0069] like Figures 1 to 3 As shown, the guide pipe 21 of the present invention includes a first pipe body 211 and a second pipe body 212 connected together. The first end of the first pipe body 211 is connected to the spray member 1, the second end of the first pipe body 211 is connected to the first end of the second pipe body 212, and the second end of the second pipe body 212 is connected to the outlet 331. The cross-sectional area of ​​the first pipe body 211 gradually decreases along the direction close to the outlet 331, and the cross-sectional area of ​​the second pipe body 212 gradually increases along the direction close to the outlet 331.

[0070] By configuring the guide pipe 21 as a first pipe body 211 and a second pipe body 212, the hot fluid ejected by the spraying component 1 can first pass through the first pipe body 211 for further depressurization and acceleration. On the one hand, this helps to create a negative pressure inside the first pipe body 211, making it easier to introduce external cold air into the guide cavity 20. On the other hand, it promotes gas-liquid separation of the hot fluid inside the first pipe body 211, causing water vapor to rise and condense when it meets the cold air introduced from the first air inlet 221, preventing high-temperature water vapor from being directly discharged and scalding the user. Then, the hot fluid flowing out of the first pipe body 211 flows into the second pipe body 212 and its flow rate is reduced in the second pipe body 212, thereby making it easier for the water in the guide cavity 20 to flow out of the second pipe body 212 more smoothly, preventing water splashing and swaying, and further improving the user experience.

[0071] It should be noted that the present invention does not impose any limitation on the specific configuration type of the guide tube 21, as long as it enables the jetting component 1 to jet high-speed fluid into the guide cavity 20 of the guide tube 21 and out of the outlet 331, etc. Such adjustments and changes to the specific configuration type of the guide tube 21 do not deviate from the principle and scope of the present invention and should be included within the protection scope of the present invention.

[0072] Preferably, the guide pipe 21 of the present invention is configured to include a first pipe body 211 and a second pipe body 212 connected together. The first end of the first pipe body 211 is connected to the spray member 1, the second end of the first pipe body 211 is connected to the first end of the second pipe body 212, and the second end of the second pipe body 212 is connected to the outlet 331. The cross-sectional area of ​​the first pipe body 211 gradually decreases along the direction close to the outlet 331, and the cross-sectional area of ​​the second pipe body 212 gradually increases along the direction close to the outlet 331.

[0073] With this configuration, compared to the forms of Embodiment 1 and Embodiment 2, the guide pipe 21 of Embodiment 3 can better introduce external airflow into the guide cavity 20, and better facilitate the gas-liquid separation of the hot water sprayed into the guide cavity 20, thereby better preventing users from being scalded by high-temperature steam. At the same time, it can also make the water outlet assembly have a better water output effect and improve the user experience.

[0074] Let S1 be the cross-sectional area of ​​the first end of the first tube 211, and S2 be the cross-sectional area of ​​the second end of the first tube 211.

[0075] It should be noted that the specific dimensions of the cross-sectional area S1 of the first end and the cross-sectional area S2 of the second end of the first tube 211 can be adjusted based on experience or experimentation, so that when the injection component 1 injects high-speed hot fluid into the guide cavity 20, the external airflow can be introduced into the guide cavity 20 more effectively, and the hot fluid in the guide cavity 20 can undergo gas-liquid separation more effectively.

[0076] After numerous experiments, the inventors discovered that when the ratio of the cross-sectional area S1 at the first end of the first tube 211 to the cross-sectional area S2 at the second end of the first tube 211 is 2.0-2.5, the water outlet has a better water output effect.

[0077] More preferably, the ratio between the cross-sectional area S1 of the first end of the first tube 211 and the cross-sectional area S2 of the second end of the first tube 211 is 2.2.

[0078] like Figure 3 As shown, the inner diameter of the first end of the first tube 211 is denoted as D1, and the inner diameter of the second end of the first tube is denoted as D2.

[0079] Therefore, S1 = π × (D1 ÷ 2) 2 ;

[0080] S² = π × (D² ÷ 2) 2 ;

[0081] S1÷S2=D1 2 ÷D2 2 ;

[0082] That is, the ratio between the cross-sectional area S1 of the first end of the first tube 211 and the cross-sectional area S2 of the second end of the first tube 211 is D1. 2 ÷D2 2 .

[0083] It should be noted that, in practical applications, those skilled in the art can set the cross-sectional area of ​​the second end of the first tube 211 to be equal to the cross-sectional area of ​​the first end of the second tube 212, or they can set the cross-sectional area of ​​the second end of the first tube 211 to be smaller than the cross-sectional area of ​​the first end of the second tube 212, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0084] Preferably, the cross-sectional area of ​​the second end of the first tube 211 is set to be equal to the cross-sectional area of ​​the first end of the second tube 212.

[0085] It should be noted that, in practical applications, those skilled in the art can configure the first tube 211 and the second tube 212 to be snap-fit ​​connected, or the first tube 211 and the second tube 212 can be connected by fasteners, or the first tube 211 and the second tube 212 can be integrally formed, etc. Such adjustments and changes to the specific connection method between the first tube 211 and the second tube 212 do not deviate from the principles and scope of the present invention, and should all be included within the protection scope of the present invention.

[0086] Preferably, the first tube body 211 and the second tube body 212 are integrally formed.

[0087] This design improves the overall integrity of the guide pipe 21 and prevents water leakage caused by poor sealing of the first pipe body 211 and the second pipe body 212.

[0088] Preferably, the inner wall of the first tube 211 of the present invention is provided with a protruding structure (not shown in the figure), which is configured to puncture the air bubbles mixed in the hot fluid when the injection member 1 injects high-speed hot fluid into the guide cavity 20.

[0089] With this design, namely by setting a protruding structure on the inner wall of the first tube 211, it is easy to puncture the air bubbles mixed in the hot water, thereby facilitating gas-liquid separation of the hot water in the guide cavity 20 and further improving the water outlet effect.

[0090] It should be noted that, in practical applications, those skilled in the art can configure the protrusion structure to extend horizontally, or to extend vertically, etc. Such adjustments and changes to the specific configuration direction of the protrusion do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0091] Preferably, the protruding structure of the present invention extends in the vertical direction.

[0092] It should be noted that, in practical applications, those skilled in the art can set the protruding structure to have a triangular cross section, or a cross-shaped cross section, or any other possible structural form, as long as it can puncture the air bubbles in the water flow. Such adjustments and changes to the specific shape of the protruding structure do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0093] For example, the cross section of the protruding structure is cross-shaped.

[0094] It should be noted that, in practical applications, those skilled in the art can configure the spraying component 1 as a high-pressure spray gun, wherein the outlet end of the high-pressure spray gun is connected to the first end of the guide cavity 20. Alternatively, the spraying component 1 can be configured as a spray pipe 11 and a nozzle, wherein the water inlet 111 is provided on the spray pipe 11, the nozzle is provided with a spray hole 121, the spray head 12 is located inside the guide cavity 20, and the hot water entering the spray pipe 11 from the water inlet 111 is sprayed into the guide cavity 20 through the spray hole 121, etc. Such adjustments and changes to the specific configuration type of the spraying component 1 do not deviate from the principle and scope of the present invention and should all be included within the protection scope of the present invention.

[0095] Continue reading Figures 1 to 3 And then refer to Figure 4 , Figure 4 This is a schematic diagram of the spraying component of the present invention.

[0096] Preferably, such as Figures 1 to 4 As shown, the spray component 1 of the present invention includes a spray pipe 11 and a nozzle disposed on the spray pipe 11. A water inlet 111 is disposed at one end of the spray pipe 11, and the nozzle is disposed at the other end of the spray pipe 11. The nozzle is provided with a spray hole 121. When installed, the nozzle is located in the flow guiding cavity 20 so that hot water entering the spray pipe 11 from the water inlet 11 is sprayed into the flow guiding cavity 20 through the spray hole 121.

[0097] By setting the spray component 1 as a spray pipe 11 and nozzle, compared to setting it as a high-pressure spray gun, the cost of the spray component 1 can be reduced, thereby reducing the cost of the water outlet assembly and further improving the user experience.

[0098] It should be noted that, in practical applications, those skilled in the art can set the number of nozzles 121 to one, or the number of nozzles 121 to multiple, etc. Such adjustments and changes to the specific number of nozzles 121 do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0099] Preferably, such as Figure 3 and Figure 4 As shown, there are multiple nozzles 121, which are distributed at intervals on the nozzle head.

[0100] Preferably, the orifice diameter of the spray hole 121 is 0.8-2 mm, and more preferably, the orifice diameter of the spray hole 121 is 1.5 mm.

[0101] It should be noted that, in order to achieve a better spraying effect, the dimensions of the water inlet 111 and the nozzle 121 need to be designed reasonably.

[0102] The sum of the cross-sectional areas of all nozzles 121 is denoted as S3, and the cross-sectional area of ​​the water inlet 111 is denoted as S4.

[0103] Through numerous experiments, the inventors discovered that when the ratio between the sum of the cross-sectional areas S3 of the nozzles 121 and the cross-sectional area S4 of the inlet port 111 is 0.2-0.3, the spraying effect of the spraying component 1 will be better. That is, boiling water entering the spray pipe 11 from the inlet port 111 is sprayed out through the nozzles 121 to form a high-speed jet. Since the cross-sectional area of ​​the nozzles 121 is smaller than that of the inlet port 111, the flow velocity of the boiling water will increase when it passes through the reduced flow cross section. The pressure potential energy of the hot water can be converted into kinetic energy through the nozzle.

[0104] More preferably, the ratio between the sum of the cross-sectional areas S3 of the nozzles 121 and the cross-sectional area S4 of the water inlet 111 is 0.25.

[0105] like Figure 3 As shown, the inner diameter of the nozzle is set to d1, the number of nozzles is n, the inner diameter of the water inlet is d2, and the inner diameter of each nozzle is set to be equal.

[0106] Therefore, the sum of the cross-sectional areas of nozzle 121, S3, is equal to n × π × (d1 ÷ 2). 2 ;

[0107] The cross-sectional area of ​​the water inlet 111 is denoted as S4 = π × (d² ÷ 2). 2 .

[0108] That is, the ratio between the sum of the cross-sectional areas S3 of the nozzles 121 and the cross-sectional area S4 of the water inlet 111 is S3 ÷ S4 = n × d1 2 ÷d2 2 .

[0109] It should be noted that, in practical applications, those skilled in the art can set the spraying component 1 and the end cap 22 in a relatively fixed and non-contact manner, or the spraying component 1 can be set to be installed on the end cap 22, or the spraying component 1 can be set to be integrally formed with the end cap 22, etc. Such adjustments and changes to the specific connection method between the spraying component 1 and the end cap 22 do not deviate from the principle and scope of the present invention, and should all be included within the protection scope of the present invention.

[0110] Preferably, such as Figure 3 and Figure 4 As shown, the spray pipe 11 of the present invention is provided with a first mounting structure 112, and the end cap 22 is provided with a second mounting structure 222. When installed, the first mounting structure 112 and the second mounting structure 222 cooperate to install the spray member 1 on the end cap 22.

[0111] This design facilitates the installation of the spray component 1 on the flow guide component 2, thereby making it easier to assemble and disassemble the water outlet assembly, replace and clean the components of the water outlet assembly, and further enhance the user experience.

[0112] It should be noted that, in practical applications, those skilled in the art can configure the first mounting structure 112 and the second mounting structure 222 as a structure in which a snap and a slot cooperate, or they can configure the first mounting structure 112 and the second mounting structure 222 as a structure in which an internal thread and an external thread 312 cooperate, or they can configure the first mounting structure 112 and the second mounting structure 222 as any other possible form, etc. Such adjustments and changes to the specific structural forms of the first mounting structure 112 and the second mounting structure 222 do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0113] Preferably, such as Figure 3 As shown, the first mounting structure 112 has an external thread 312, and the second mounting structure 222 has an internal thread. When installed, the external thread 312 and the internal thread cooperate to install the spraying component 1 on the end cap 22.

[0114] Preferably, such as Figures 1 to 4 As shown, the spraying component 1 of the present invention is also provided with a limiting structure 113, which abuts against the end cap 22 when installed.

[0115] By setting the limiting structure 113, when the spray component 1 is installed on the end cover 22, the limiting structure 113 can abut against the end cover 22. On the one hand, it can prevent the spray component 1 from falling off due to improper installation, thus avoiding affecting the normal use of the water outlet assembly. On the other hand, it can also position the spray component 1 on the end cover, thereby enabling the rapid installation of the spray component 1 on the end cover 22 and improving the assembly efficiency of the water outlet assembly.

[0116] It should be noted that, in practical applications, those skilled in the art can set the limiting structure 113 as a limiting ring, or as a limiting block, or as a limiting rod, etc. Such adjustments and changes to the specific structural form of the limiting structure 113 do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0117] For example, such as Figures 1 to 4 As shown, the limiting structure 113 of the present invention is a limiting ring.

[0118] like Figures 1 to 3 As shown, the water outlet assembly of the present invention also includes a flow stabilizing member 3. One end of the flow stabilizing member 3 is connected to the second end of the flow guiding cavity 20, and the other end of the flow stabilizing member 3 forms a water outlet 331. The flow stabilizing member 3 is configured to enable the water in the flow guiding cavity 20 to flow out smoothly from the water outlet 331.

[0119] By setting the flow stabilizing component 3, the water flowing out from the guide cavity 20 can be buffered, making its flow rate more uniform and gentle, and preventing splashing and swaying when the water flows out from the outlet 331, thereby improving the water output effect of the water outlet assembly.

[0120] See next Figures 5 to 7 , Figure 5 This is a schematic diagram of the current stabilizing component of the present invention. Figure 1 , Figure 6 This is a schematic diagram of the current stabilizing component of the present invention. Figure 2 , Figure 7 This is a vertical cross-sectional schematic diagram of the flow stabilizing component of the present invention.

[0121] Preferably, such as Figures 5 to 7 As shown, the flow stabilizing component 3 of the present invention includes a housing 31 and a first mesh 32 and a second mesh 33 arranged sequentially inside the housing 31. The first mesh 32 is provided with a plurality of water inlet mesh holes 321, which are connected to the flow guiding cavity 20. The water outlet 331 is formed on the second mesh 33. The first mesh 32 is curved and extends toward the side away from the water outlet 331.

[0122] With this setup, when the water in the guide cavity 20 reaches the first mesh body 32, the water flow can be further slowed down and homogenized. After being filtered by the water inlet mesh 321 on the first mesh body 32, it is divided into multiple fine streams, and the flow rate of each fine stream tends to be consistent, forming a vertical, gentle, non-splashing water column that flows out from the outlet 331, further improving the water output effect.

[0123] It should be noted that, in practical applications, those skilled in the art can configure the first mesh body 32 as a conical shape extending toward the side away from the outlet 331, or the first mesh body 32 as a hemispherical shape extending toward the side away from the outlet 331, etc. Such adjustments and changes to the specific configuration shape of the first mesh body 32 do not deviate from the scope and range of the present invention, and should all be included within the protection scope of the present invention.

[0124] Preferably, such as Figure 3 , Figure 5 and Figure 7 As shown, the first mesh body 32 of the present invention is a conical shape extending toward the side away from the outlet 331.

[0125] Preferably, such as Figure 3 , Figure 5 and Figure 7 As shown, the first mesh body 32 of the present invention is also provided with a diversion structure 322, which is located at the center of the first mesh body 32 and extends toward the side away from the outlet 331.

[0126] By setting the diversion structure 322, on the one hand, the water flow from the guide cavity 20 can be diverted so that the water flow can flow evenly to the surface of the first mesh 32, thereby further improving the flow stabilization effect; on the other hand, the structural strength of the first mesh 32 can be increased, thereby improving the service life of the water outlet assembly.

[0127] Preferably, such as Figure 3 and Figure 7 As shown, the flow stabilizing component 3 of the present invention further includes a third mesh body 34, which is located between the first mesh body 32 and the second mesh body 33. The third mesh body 34 is provided with a water passage hole 341, and the housing 31 is provided with a second air inlet 311, which is located between the second mesh body 33 and the third mesh body 34, so as to introduce external airflow into the housing 31 and thereby reduce the flow rate of water flowing out from the water passage hole 341.

[0128] With this configuration, the air entering the housing 31 from the second air inlet 311 can further buffer the water flow, thereby reducing the impact force of the water flow from the third mesh 34, resulting in a lower flow rate and better water output.

[0129] It should be noted that, in practical applications, those skilled in the art can set the number of second air inlets 311 to one, or the number of second air inlets 311 to multiple, etc. Such adjustments and changes to the specific number of second air inlets 311 do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0130] Preferably, such as Figure 5 As shown, the present invention has a plurality of second air inlets 311, which are distributed at intervals along the circumference of the housing 31.

[0131] This setup allows for more even air intake, which in turn more effectively buffers the water flow, resulting in a more uniform water flow rate and further improving the water output.

[0132] It should be noted that, in practical applications, those skilled in the art can configure the flow stabilizing component 3 as an integral part of the flow guiding component 2, or the flow stabilizing component 3 as detachably connected to the flow guiding component 2, etc. Such adjustments and changes to the specific connection method between the flow stabilizing component 3 and the flow guiding component 2 do not deviate from the principles and scope of the present invention, and should all be included within the protection scope of the present invention.

[0133] Preferably, the flow stabilizing component 3 and the flow guiding component 2 are detachably connected.

[0134] It should be noted that, in practical applications, those skilled in the art can configure the flow stabilizing component 3 and the flow guiding component 2 to be connected by fasteners, or they can configure the flow stabilizing component 3 and the flow guiding component 2 to be snap-fitted, or they can configure the flow stabilizing component 3 and the flow guiding component 2 to be threaded, etc. Such adjustments and changes to the specific detachable connection method between the flow stabilizing component 3 and the flow guiding component 2 do not deviate from the principles and scope of the present invention, and should all be included within the protection scope of the present invention.

[0135] Preferably, such as Figure 3 and Figure 7 As shown, the flow stabilizing component 3 is provided with an external thread 312, and the flow guiding component 2 is provided with an internal thread 2121 that is compatible with the external thread 312. When installed, the external thread 312 and the internal thread 2121 cooperate to install the flow stabilizing component 3 on the flow guiding component 2.

[0136] This design facilitates the installation and disassembly of the flow stabilizer 3 and the flow guide 2, thereby making it easier to clean the water outlet assembly. Furthermore, by setting the flow stabilizer 3 and the flow guide 2 in a threaded connection, the sealing performance and installation stability of the flow stabilizer 3 on the flow guide 2 can be improved.

[0137] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
