Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, and in particular to a water nozzle structure and a water purifier comprising the same. Background Art

[0002] As commercial water purifiers become more and more popular, people's requirements for the use of commercial water purifiers are getting higher and higher. In many usage scenarios, water purifiers are required to output not only normal temperature water but also hot water. When the water purifier outputs hot water, it shares the same water spout with normal temperature water. Users of existing water purifiers have reported abnormal water temperature during use. Specifically, the water temperature flowing out of the side wall and the middle area of ​​the spout is different after the water flows out, that is, the water temperature is uneven. On the one hand, the uneven water temperature may scald the user's hands, resulting in a poor user experience. On the other hand, in order to make the water temperature uniform, the water flow needs to be emptied for a long time, and it can only be used when the water temperature reaches a uniform level. This also wastes water resources and increases the user's usage cost accordingly. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defects in the prior art that the water temperature of the water outlet of the faucet is uneven, which may easily scald the user, and it takes a long time to reach a uniform water temperature when the water is discharged empty, and to provide a faucet structure and a water purifier including the same.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A faucet structure is provided at a water outlet of a water purifier, and comprises:

[0006] a cavity, the cavity being in communication with a water path of the water purifier;

[0007] The guide member is arranged in the cavity along the horizontal direction, the top middle area of ​​the guide member has a protrusion and the protrusion is higher than the edge area, the guide member is provided with a plurality of guide holes around the protrusion, and the plurality of guide holes penetrate the guide member and are arranged at intervals.

[0008] In this solution, a guide piece is provided to mix water after the water flows into the cavity. The water flows from the protrusion to the edge area and then flows out through the guide hole. When the water flow is hot water, the hot water after diversion through the guide hole will re-converge after passing through the guide piece due to the water's own tension. At this time, the temperature of the converged water flow tends to be consistent, that is, the temperature of the water flow on the side wall of the cavity at the water outlet and the water flow at the axis tend to be consistent, achieving uniform water temperature after mixing, improving the user experience, and reducing user waiting. In addition, the multiple guide holes arranged at intervals also make the shape of the water flow passing through the guide piece more uniform and beautiful, reducing the situation of water splashing.

[0009] Preferably, the guide hole is a fan-shaped hole, and the larger end of the fan-shaped hole is arranged away from the protrusion.

[0010] In this solution, the above arrangement is used to ensure the flow rate of water flow, and the flow rate of water flow outflow is not reduced due to the arrangement of the guide member. In addition, the fan-shaped holes can further adjust the shape of the water flow, ensuring the confluence effect.

[0011] Preferably, the edge from the protrusion to the guide member forms an inclined slope gradually away from the horizontal direction.

[0012] In this solution, the above arrangement enables water to quickly enter the diversion hole, thereby improving water outlet efficiency.

[0013] Preferably, the guide member is further provided with a through hole, and the through hole is located at the axis of the guide member and coincides with the axis of the cavity.

[0014] In this solution, the through hole can also guide the water flow. When guiding the water, the through hole and the guide hole cooperate together. When the water flows out of the through hole, it merges with the water flowing out of the guide hole to mix the water to obtain a water flow with uniform water temperature, further improving the mixing efficiency.

[0015] Preferably, the cavity comprises an upper cavity and a lower cavity, the upper cavity and the lower cavity are sealed and connected, and the flow guide is located in the lower cavity.

[0016] In this solution, the installation of the guide member is facilitated by providing split upper and lower cavities.

[0017] Preferably, the lower cavity has a guide section and a water outlet section, the guide section is located above the water outlet section, the guide section is a conical slope and the smaller end of the conical slope is connected to the water outlet section, the guide member is located in the guide section and has an interference fit with the inner wall of the guide section.

[0018] In this solution, a guide section is provided to accelerate the water flow in the cavity to flow toward the guide member and reduce the residual water flow on the inner wall of the cavity, thereby preventing the residual water flow from contacting bacteria in the air and causing mold in the faucet.

[0019] Preferably, the upper cavity is connected with an exhaust pipe.

[0020] In this solution, an exhaust pipe is provided to keep the air pressure in the cavity consistent with the external air pressure, and the external air pressure is used to discharge the residual water flow in the cavity out of the cavity to prevent the water nozzle from dripping after use.

[0021] Preferably, a first water inlet and a second water inlet are provided in the upper cavity, and the first water inlet and the second water inlet are connected to water paths with different temperatures.

[0022] In the present solution, a first water inlet and a second water inlet are provided so that water can be introduced through the first water inlet or the second water outlet separately when the user has different water temperature requirements. In addition, water is introduced through the first water inlet and the second water inlet simultaneously to mix water in the cavity through a guide member to obtain a water flow and temperature that meets the actual needs of the user.

[0023] A water purifier comprises the water nozzle structure as described above.

[0024] In this solution, the water purifier includes the above-mentioned water nozzle structure, so that when supplying water to the user, it can output water flow with uniform water temperature instead of water flow with different temperatures in different areas. In addition, the water purifier has a more beautiful water shape after the water is guided by the guide member when discharging water.

[0025] Preferably, the water purifier includes a first solenoid valve and a second solenoid valve, the first solenoid valve is connected to the water nozzle structure through a first water inlet, the second solenoid valve is connected to the water nozzle structure through a second water inlet, and water flowing out of the first water inlet and the second water inlet is mixed through a guide member of the water nozzle structure.

[0026] In this solution, the first solenoid valve and the second solenoid valve are used to open or close the first water inlet and the second water inlet respectively, and the water flows at different temperatures are mixed after entering the water nozzle through the water nozzle structure to achieve uniform water temperature at the outlet.

[0027] The positive progress of the utility model is that the utility model is provided with a guide member to mix water after the water flows into the cavity through the guide member, and the water flows from the protrusion to the edge area and then flows out through the guide hole. When the water flow is hot water, the hot water after diversion through the guide hole will re-converge after passing through the guide member due to the tension of the water itself. At this time, the temperature of the converged water flow tends to be consistent, that is, the temperature of the water flow on the side wall of the water outlet of the cavity and the water flow at the axis tend to be consistent, so that the water temperature is uniform after mixing, which improves the user's experience and reduces the user's waiting time. In addition, the multiple guide holes arranged at intervals also make the shape of the water flow passing through the guide member more uniform and beautiful, reducing the situation of water splashing.

[0050] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0051] This embodiment provides a faucet structure 1, the specific structure is as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the faucet structure 1 is arranged at the water outlet of the water purifier, and the faucet structure 1 comprises: a cavity 11, and the cavity 11 is connected with the water channel of the water purifier;

[0052] The guide member 2 is arranged in the cavity 11 along the horizontal direction. The top middle area of ​​the guide member 2 has a protrusion 21 and the protrusion 21 is higher than the edge area. The guide member 2 is provided with a plurality of guide holes 22 around the protrusion 21. The plurality of guide holes 22 penetrate the guide member 2 and are arranged at intervals.

[0053] Specifically, a cavity 11 is provided in the faucet structure 1, and the water purifier guides the filtered water flow to the user end through the cavity 11. The guide member 2 is a cylindrical structure and a protrusion 21 is provided on the top of the guide member 2. The protrusion 21 is located at the axis of the guide member 2, that is, the middle area, and the axis of the guide member 2 coincides with the axis of the cavity 11. The protrusion 21 is provided so that when the water flows from the cavity 11, it flows from the protrusion 21 to the edge area of ​​the guide member 2, that is, it is diverted, and enters the guide hole 22. The guide holes 22 arranged around the protrusion 21 will form multiple water flows after the water flows through the guide member 2. The multiple water flows converge in the cavity 11 again due to the tension of the water flow itself. When the water flow is hot water, the converged water flow is fully mixed to achieve water temperature balance. In other words, the water temperature of the surrounding side of the water flow flowing out of the faucet structure 1 is consistent with that of the middle area.

[0054] It can be understood that the guide member 2 is arranged in the cavity 11, which itself is a barrier to the water flow. When part of the water flow is blocked, the residual water flow in the water channel of the water purifier does not meet the water temperature required by the user. The water is mixed in the cavity 11 by blocking part of the water flow through the guide member 2, that is, the water is mixed before flowing into the guide hole 22 to make the water temperature tend to be consistent, and then converge again through the guide hole 22 to achieve uniform water temperature when the water comes out, thereby meeting the actual needs of the user, improving the user experience, and reducing the user's waiting time.

[0055] In addition, the multiple guide holes 22 arranged at intervals make the shape of the water flow passing through the guide member 2 more uniform and beautiful, reducing the splashing of water.

[0056] In this embodiment, the guide hole 22 is a fan-shaped hole, and the larger end of the fan-shaped hole is arranged away from the protrusion 21.

[0057] Specifically, the fan-shaped hole includes a smaller end and a larger end, which is the prior art, wherein the smaller end is arranged toward the protrusion 21, and the larger end is arranged away from the protrusion 21, which makes the water flow entering the guide hole 22 smaller near the middle area of ​​the guide member 2, and larger away from the middle area of ​​the guide member 2. The smaller water flow is prone to mutual tension of water flow tension, while the larger water flow can meet the user's water demand, avoiding the reduction of water outflow due to the setting of the guide member 2. In addition, the fan-shaped hole can further adjust the shape of the water flow, ensuring that the water shape of the water outlet is more beautiful.

[0058] In other embodiments, the guide hole 22 may also be a water drop-shaped hole, and its purpose is also to converge the water flow after passing through the guide member 2, so as to obtain a water flow with uniform water temperature after mixing the water.

[0059] In this embodiment, the edge of the protrusion 21 to the guide member 2 forms an inclined slope that gradually moves away from the horizontal direction.

[0060] Specifically, the height of the protrusion 21 is higher than the edge area of ​​the guide member 2, and a slope is formed between the protrusion 21 and the edge area of ​​the guide member 2. From the appearance, the slope is a conical structure. The slope is used to guide the water flowing toward the protrusion 21 into the guide hole 22. Compared with other structures or surfaces, the water can enter the guide hole 22 more quickly to reduce the user's waiting time, quickly mix the water evenly and keep the water temperature consistent before discharging the water, thereby improving the water discharge efficiency.

[0061] In this embodiment, the flow guide 2 is further provided with a through hole 23 , which is located at the axis of the flow guide 2 and coincides with the axis of the cavity 11 .

[0062] Specifically, the through hole 23 is a circular hole and is located at the axis of the guide member 2. The through hole 23 is provided so that the water flow can be directly guided out from the middle area of ​​the guide member 2 when the water flows through the guide member 2. It can be understood that the multiple water flows guided out from the guide hole 22 converge toward the middle area of ​​the guide member 2 when converging, and when the through hole 23 is provided, an additional water flow is added to the middle area of ​​the guide member 2. This makes the multiple water flows guided out from the guide hole 22 converge with the additional water flow near the middle area of ​​the guide member 2 due to the water's own tension when converging, thereby shortening the converging time of the multiple water flows, further improving the water mixing efficiency, and thereby obtaining a water flow with uniform water temperature and beautiful water shape through the guide member 2.

[0063] In this embodiment, the cavity 11 includes an upper cavity 111 and a lower cavity 112 . The upper cavity 111 and the lower cavity 112 are sealed and connected, and the guide member 2 is located in the lower cavity 112 .

[0064] Specifically, the upper cavity 111 is used to communicate with the water path in the water purifier, so that when the water purifier is started, water flows from the water path into the upper cavity 111, and flows through the lower cavity 112 and the guide member 2, and finally flows out from the water outlet of the lower cavity 112 for the user to take. The upper cavity 111 is a cylindrical structure, and the size of the upper cavity 111 is larger than the size of the lower cavity 112, so that when there are multiple water paths in the water purifier, multiple water paths can be opened at the same time and water can be mixed in the upper cavity 111. The upper cavity 111 and the lower cavity 112 are sealed and connected by a rotary fusion method to ensure the sealing of the split cavity 11 and facilitate the installation of the guide member 2.

[0065] In this embodiment, the lower cavity 112 has a guide section 1121 and a water outlet section 1122. The guide section 1121 is located above the water outlet section 1122. The guide section 1121 is a conical slope and the smaller end of the conical slope is connected to the water outlet section 1122. The guide member 2 is located in the guide section 1121 and has an interference fit with the inner wall of the guide section 1121.

[0066] Specifically, the guide section 1121 is a conical structure and is used to accommodate the guide member 2. The water outlet section 1122 is a cylindrical structure. The larger end of the conical structure is sealed and connected to the upper cavity 11. The slope formed by the conical structure can gather water flow to facilitate the flow of water to the guide member 2 and mix the water. By setting the guide section 1121, the water flow in the cavity 11 can be accelerated to flow to the guide member 2, and the residual water flow on the inner wall of the cavity 11 can be reduced to prevent the residual water flow from contacting bacteria in the air and getting moldy in the faucet.

[0067] In this embodiment, the upper cavity 111 is connected to the exhaust pipe 3 .

[0068] Specifically, the exhaust pipe 3 is arranged in the vertical direction and one end of the exhaust pipe 3 is located at the top of the water purifier, and the other end of the exhaust pipe 3 is sealed and connected to the upper cavity 111. When the water purifier discharges water, the water flows from the water path of the water purifier to the faucet structure 1, and the exhaust pipe 3 arranged on the upper cavity 111 keeps the air pressure in the faucet structure 1 consistent with the external air pressure, so that the residual water flow in the cavity 11 is discharged through the air pressure, and the internal environment of the cavity 11 is kept relatively dry after use, to prevent the growth of mold with bacteria in the air. At the same time, the residual water flow in the cavity 11 is discharged from the cavity 11 by the external air pressure to prevent the faucet from dripping after use. To enhance the user experience and drinking water safety. The exhaust pipe 3 can be a silicone tube or a hard, high-temperature resistant PE tube material. This is a prior art and will not be described in detail here.

[0069] In this embodiment, a first water inlet 4 and a second water inlet 5 are provided in the upper cavity 111 , and the first water inlet 4 and the second water inlet 5 are connected to water paths with different temperatures.

[0070] Specifically, the first water inlet 4 and the second water inlet 5 are arranged on both sides of the upper cavity 111 in a horizontal direction. The first water inlet 4 is connected to the water path of the normal temperature water in the water purifier, and the second water inlet 5 is connected to the water path of the hot water in the water purifier. They can also be interchanged to meet the different water intake needs of users, so that users can not only get drinking water at normal temperature, but also get hot water for drinking. Of course, users can also open the first water inlet 4 and the second water inlet 5 synchronously according to different needs, and adjust the temperature in the faucet structure 1 according to the water flow ratio required for a certain temperature, so as to obtain water with a consistent water temperature and meeting special needs after mixing water through the guide member 2.

[0071] This embodiment also provides a water purifier, which includes the above-mentioned water nozzle structure 1.

[0072] Specifically, the mounting plate of the water purifier for mounting the faucet structure 1 is located at the bottom of the water purifier, and a mounting hole is provided on the mounting plate. The faucet structure 1 is inserted into the mounting hole and screwed to the mounting plate by self-tapping screws. When the water purifier is turned on, water flows of different temperatures flow through the faucet structure 1 in the water channel and are mixed by the guide member 2 to divert the water flow to form a more beautiful water flow. At the same time, the guide member 2 also mixes water flows of different temperatures so that the water temperature of the edge area and the middle area of ​​the water flow is consistent when the water flows out, that is, the water flow with uniform water temperature. This is to enhance the user experience.

[0073] like Figure 6 As shown, in this embodiment, the water purifier also includes a first solenoid valve 6 and a second solenoid valve 7. The first solenoid valve 6 is connected to the faucet structure 1 through the first water inlet 4, and the second solenoid valve 7 is connected to the faucet structure 1 through the second water inlet 5. Water flowing out of the first water inlet 4 and the second water inlet 5 is mixed through the guide member 2 of the faucet structure 1.

[0074] Specifically, the first solenoid valve 6 and the second solenoid valve 7 are both arranged on the mounting plate and correspond to the first water inlet 4 and the second water inlet 5 respectively. The first solenoid valve 6 and the second solenoid valve 7 are pressure-free solenoid valves. The first solenoid valve 6 and the second solenoid valve 7 are used to open or close the first water inlet 4 and the second water inlet 5 accordingly, and the water flows at different temperatures enter the water nozzle through the water nozzle structure 1 to mix the water so as to achieve uniform water temperature at the outlet.

[0075] A bracket for fixing is also provided on the mounting plate corresponding to the first solenoid valve 6 and the second solenoid valve 7. Folding edges are provided on both sides of the bracket to enhance the stability of the bracket. An accommodating hole for accommodating the first solenoid valve 6 or the second solenoid valve 7 is provided on the bracket. The bracket is screwed to the mounting plate by self-tapping screws.

Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
