[0002] With economic development and the improvement of living standards, consumers are paying more and more attention to healthy water use and drinking water, and their requirements for water use are getting higher and higher. As a water treatment equipment that can deeply filter and purify water according to water use requirements, water purifiers are recognized and favored by more and more consumers, especially water purifiers with heating function, which can not only provide purified water at room temperature, but also provide hot water to meet the various needs of users. Water purifiers with heating function usually include a filter unit, a heating unit and a water outlet. The filter unit filters raw water such as municipal tap water into pure water for output. The pure water can be transported to the heating unit for heating, and the heated hot water can be transported to the water outlet for discharge. However, the existing water outlet lacks water type optimization design. The incoming normal temperature water or hot water directly rushes into the water outlet, and the flow rate is fast and unstable, making the discharged water flow erratic. Not only is the aesthetics not good, but it is also easy to cause water droplets to splash. Utility Model Content

[0020] 4. As a preferred embodiment of the present application, the second limiting portion includes a plurality of limiting ribs arranged at intervals along the circumference of the water outlet nut, the plurality of limiting ribs protrude from the inner surface of the water outlet nut and abut against the side wall of the bunching guide tube, so that the limiting ribs form radial limitations on the bunching guide tube to prevent the bunching guide tube from radially shifting; moreover, an exhaust channel for discharging steam is formed between two adjacent limiting ribs, which will not hinder the steam discharge; in addition, a limiting hook is provided at the bottom end of the limiting rib, and the limiting hook abuts against the bottom end of the bunching guide tube, so that not only can the limiting hook abut against the bunching guide tube to give the operator a prompt that the bunching guide tube has been inserted into the water outlet nozzle, but also the bunching guide tube can be axially limited.

[0021] 5. As a preferred embodiment of the present application, the bottom surface of the water outlet cavity is provided with guide ribs extending upward, and the guide ribs are arranged circumferentially around the water outlet.

[0042] In the embodiments of the present application, a water outlet and a water purifier with a heating function are provided. For the convenience of explanation and understanding, the following contents provided in the present application are all described based on the illustrated product structure. Of course, those skilled in the art can understand that the above structure is only used as a specific example and schematic description, and cannot constitute a specific limitation on the technical solution provided in the present application.

[0043] Reference Figures 1 to 8 As shown, a water outlet nozzle provided in the present application includes a main body 1, a water outlet nut 2 and a bunching guide pipe 3, the main body 1 has a water outlet cavity 111 and a water inlet 112 and a water outlet 113 respectively connected to the water outlet cavity 111; the water outlet nut 2 is threadedly connected to the main body 1; one end of the bunching guide pipe 3 is connected to the water outlet 113, and the other end is passed through the water outlet nut 2, so that the main body 1 discharges water to the outside through the bunching guide pipe 3, and an exhaust channel 4 is formed between the bunching guide pipe 3 and the water outlet nut 2 to connect the water outlet cavity 111 with the outside atmosphere.

[0044] Compared with the water outlet in the prior art that directly discharges water through the water outlet nut, the water outlet provided in the present application is provided with a bunching guide tube 3, one end of which is connected to the water outlet 113, and the other end is passed through the water outlet nut 2, so that the main body 1 discharges water outward through the bunching guide tube 3, and the bunching guide tube 3 has a bunching and rectifying effect, which can gather the turbulent water flow flowing out of the water outlet 113 into a beam, optimize the water shape when the water flow is discharged from the water outlet 113, improve the drainage perception, and reduce the splashing of water droplets during drainage; in addition, an exhaust channel 4 is formed between the bunching guide tube 3 and the water outlet nut 2 to connect the water outlet cavity 111 with the outside atmosphere, so that when the water outlet is discharging hot water, the hot water is discharged from the bunching guide tube 3, and the steam generated by the hot water is discharged from the exhaust channel 4, so that water vapor separation is achieved, the steam content in the hot water is greatly reduced, and the water jet phenomenon is reduced.

[0045] Specifically, the water outlet nozzle can be applied to a water purifier with a heating function, such as a water purifier and a heat purifier, a desktop water purifier, etc. The water inlet 112 of the water outlet nozzle is connected to the heating device in the water purifier. The hot water heated and output by the heating device enters the water outlet cavity 111 from the water inlet 112 of the water outlet nozzle. The hot water is discharged from the bunching guide pipe 3, and the generated steam is discharged from the exhaust channel 4, thereby reducing the jet phenomenon at the water outlet 113. In a preferred embodiment, in order to facilitate the processing and molding of the water outlet nozzle, the water outlet nozzle can include a box body 11 and a cover body 12 that are separately arranged. The water outlet cavity 111, the water inlet 112, and the water outlet 113 are formed in the box body 11. The cover body 12 is used to cover the water outlet cavity 111. In order to ensure the sealing of the water outlet cavity 111, the box body 11 and the cover body 12 can be ultrasonically welded together.

[0046] As a preferred embodiment of the present application, the main body 1 is provided with a first limiting portion, and the water outlet nut 2 is provided with a second limiting portion, and the top and bottom ends of the bunching guide tube 3 are respectively limited by the first limiting portion and the second limiting portion, so that the bunching guide tube 3 is limited between the main body 1 and the water outlet nut 2, ensuring installation reliability, preventing the bunching guide tube 3 from shifting, and making the bunching guide tube 3 stably connected with the water outlet 113, so as to ensure a stable and effective bunching and guiding effect.

[0047] Regarding the specific structure of the first limiting portion, in a preferred embodiment, as Figure 2 and Figure 3 As shown, the first limiting portion is constructed as a limiting tube 114 connected to the water outlet 113, the top end of the bunching guide tube 3 is upwardly inserted into the limiting tube 114, and the limiting tube 114 is provided with a limiting protrusion 1141, and the limiting protrusion 1141 abuts against the top end of the bunching guide tube 3 to form an axial limit for the bunching guide tube 3. Those skilled in the art can understand that, the first limiting portion is constructed as a limiting tube 114 connected to the water outlet 113, and the top end of the bunching guide tube 3 is inserted upward into the limiting tube 114, so that the limiting tube 114 forms a radial limit on the bunching guide tube 3 to prevent the bunching guide tube 3 from radially offset, and the limiting tube 114 is provided with a limiting protrusion 1141, and the limiting protrusion 1141 abuts against the top end of the bunching guide tube 3, so that not only can the limiting protrusion 1141 abut against the bunching guide tube 3 to give the operator a prompt that the bunching guide tube 3 has been inserted into the limiting tube 114 in place, but also the bunching guide tube 3 is axially limited to prevent the bunching guide tube 3 from being inserted into the water outlet cavity 111 and affecting the normal drainage of the water outlet 113.

[0048] Furthermore, if Figure 3As shown, a notch 1142 is provided on the wall of the limiting tube 114 so that the limiting tube 114 can expand outward when the bunching flow guide tube 3 is inserted into the limiting tube 114. It can be understood by those skilled in the art that by providing the notch 1142 on the limiting tube 114, the elastic expansion capacity of the limiting tube 114 is increased to a certain extent, so that during the process of inserting the bunching flow guide tube 3 into the limiting tube 114, the limiting tube 114 can expand outward, and after expansion, it is convenient to insert the bunching flow guide tube 3. After the bunching flow guide tube 3 is inserted, the limiting tube 114 contracts and tightens the bunching flow guide tube 3. In order to ensure the structural strength of the limiting tube 114, a plurality of reinforcing ribs 115 can be provided at intervals on the outside of the limiting tube 114.

[0049] Regarding the specific structure of the second limiting portion, in a preferred embodiment, as Figure 6 , Figure 7 and Figure 8 As shown, the second limiting portion includes a plurality of limiting ribs 21 arranged at intervals along the circumference of the water outlet nut 2, the plurality of limiting ribs 21 protrude from the inner surface of the water outlet nut 2 and abut against the side wall of the bunching guide tube 3, a limiting hook 211 is provided at the bottom end of the limiting rib 21, the limiting hook 211 abuts against the bottom end of the bunching guide tube 3 to form an axial limit for the bunching guide tube 3. It can be understood by those skilled in the art that a plurality of limiting ribs 21 protrude from the inner surface of the water outlet nut 2 and abut against the side wall of the bunching guide tube 3, so that the limiting ribs 21 form radial limitations on the bunching guide tube 3 to prevent the bunching guide tube 3 from radially offset; moreover, an exhaust channel 4 for discharging steam is formed between two adjacent limiting ribs 21, which will not hinder the steam discharge; in addition, a limiting hook 211 is provided at the bottom end of the limiting rib 21, and the limiting hook 211 abuts against the bottom end of the bunching guide tube 3, so that not only can the limiting hook 211 abut against the bunching guide tube 3 to give the operator a prompt that the bunching guide tube 3 has been inserted into the water outlet nozzle, but also the bunching guide tube 3 can be axially limited.

[0050] Furthermore, if Figure 8As shown, the top of the limiting rib 21 is provided with a guiding slope 212 for guiding the bunching flow guide tube 3 to cooperate with the limiting rib 21, one end of the guiding slope 212 is at a high position away from the bunching flow guide tube 3, and the other end is at a low position close to the bunching flow guide tube 3. It can be understood by those skilled in the art that, in order to ensure the tightening effect of the limiting rib 21 on the bunching flow guide tube 3, before the bunching flow guide tube 3 is inserted into the limiting rib 21, the space enclosed by the plurality of limiting ribs 21 is smaller than the diameter of the bunching flow guide tube 3, which makes it difficult to insert the bunching flow guide tube 3 and easily forms an obstruction to the bunching flow guide tube 3 when the bunching flow guide tube 3 is inserted. Therefore, by providing the guiding slope 212 at the top of the limiting rib 21, the bunching flow guide tube 3 can be inserted along the guiding slope 212, and the plurality of limiting ribs 21 are expanded outward during the insertion process, so that the limiting rib 21 tightens the bunching flow guide tube 3 after the insertion.

[0051] As a preferred embodiment of the present application, Figure 2 , Figure 4 and Figure 5 As shown, the water outlet 113 is formed on the bottom surface of the water outlet cavity 111, and the bottom surface of the water outlet cavity 111 is provided with a guide rib 116 extending upward, and the guide rib 116 is arranged circumferentially around the water outlet 113, and the guide rib 116 encloses an air intake channel 1161 connecting the water outlet cavity 111 with the exhaust channel 4. The water outlet 113 is formed on the bottom surface of the water outlet cavity 111, and the guide rib 116 extends upward from the bottom surface of the water outlet cavity 111, so that the guide rib 116 is higher than the water outlet 113 as a whole. The guide rib 116 surrounds the air inlet channel 1161 that connects the water outlet cavity 111 with the exhaust channel 4, so that the guide rib 116 is as high as possible from the liquid level in the water outlet cavity 111 during the drainage process of the water outlet nozzle. Hot water is discharged from the water outlet 113, and the steam rises to the top of the guide rib 116 and enters the air inlet channel 1161 and is finally discharged from the exhaust channel 4, which is helpful for water vapor separation and reduces the steam content in the hot water.

[0052] Furthermore, if Figure 5As shown, the top of the guide rib 116 is provided with a downwardly concave drainage notch 1162, so that when the liquid level in the water outlet chamber 111 is higher than the drainage notch 1162, the water flow can enter the air inlet channel 1161 through the drainage notch 1162. When the water outlet nozzle discharges water with a small flow, the liquid level in the water outlet chamber 111 will basically not be higher than the guide rib 116, so that the water flow is completely discharged through the bunching guide pipe 3, and when the water outlet nozzle discharges water with a large flow, causing the liquid level in the water outlet chamber 111 to be higher than the guide rib 116, in addition to the water flow discharged from the water outlet 113, another part of the water flow enters the air inlet channel 1161 through the drainage notch 1162, so that at least part of the air inlet channel 1161 and the exhaust channel 4 participate in the drainage process together with the water outlet 113, and hot water enters the air inlet channel 1161 from the drainage notch 1162, and will not fill up the space in the air inlet channel 1161, and a part of the air inlet channel 1161 is reserved for exhaust.

[0053] In a preferred embodiment, Figure 4 and Figure 5 As shown, the air inlet channel 1161 is provided with a partition rib 1163, and two of the partition ribs 1163 are respectively located on both sides of the drainage notch 1162. The two partition ribs 1163 divide the air inlet channel 1161 into three channels, wherein the channel between the two partition ribs 1163 is located directly below the drainage notch 1162, which helps the water entering the air inlet channel 1161 from the drainage notch 1162 to be discharged from between the two partition ribs 1163, so that the water flow does not enter the channels on both sides of the two partition ribs 1163 as much as possible. The channels on both sides are used to discharge steam, thereby helping the water vapor to be separated under the action of the two partition ribs 1163.

[0054] The present application provides a water purifier with a heating function, including a filter unit and a heating unit connected to the filter unit, and also includes a water outlet as described above, and the hot water outlet of the heating unit is connected to the water inlet 112 of the water outlet. Specifically, the filter unit filters the raw water into pure water, and the pure water can be transported to the heating unit for heating. The hot water output by the heating unit can be transported to the water outlet, and the hot water is discharged from the bunching guide pipe 3 to optimize the water shape when the water flows out of the water outlet 113, improve the drainage perception, and reduce the phenomenon of water droplets splashing during drainage. The steam generated by the hot water is discharged from the exhaust channel 4 to achieve water vapor separation, greatly reducing the steam content in the hot water, thereby reducing the water jet phenomenon. Since the water purifier includes the water outlet in any of the above embodiments and examples, the advantages of the water purifier including the water outlet are not repeated here.

[0055] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0056] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.
