DETAILED DESCRIPTION

[0040] In order to make the above objectives, characteristics and advantages of the present application more obvious and understandable, the specific embodiments of the present application are described in detail below with reference to the drawings. In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the concept of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0041] As shown in Figures 1 to 7 In one embodiment, a water nozzle assembly 10 is provided, which includes a water nozzle body 11 having a water passage cavity 113 and an air passage cavity A 114. The water nozzle body 11 is provided with an air outlet hole A 1141 communicating with the air passage cavity A 114. The water nozzle body 11 is provided with a first water inlet hole 1131 and a water outlet hole 1133, both of which communicate with the water passage cavity 113. The water nozzle body 11 further includes a flow blocking wall.

[0042] The water passage cavity 113 is provided with a flow limiting member 12, which is provided with a water passing hole 121 having a water outlet direction towards the flow blocking wall. The water passing hole 121 communicates a space upstream of the flow limiting member 12 with a space downstream of the flow limiting member 12. The projection of the water passing hole 121 in the water flow direction at least partially falls on the flow blocking wall. Preferably, the projection of the water passing hole 121 in the water flow direction completely falls on the flow blocking wall. The fluid hitting the flow blocking wall can continue to flow forward in the water passage cavity 113. The water passage cavity 113 and the air passage cavity A 114 are communicated by an air passing hole 1151, which is located downstream of the flow blocking wall.

[0043] The above-mentioned water nozzle assembly 10 provides that, by arranging the flow limiting member 12 in the water passage cavity 113 and further arranging the flow blocking wall, as shown in Figure 8 and Figure 9 As shown in the drawings, the water vapor mixed fluid entering from the first water inlet hole 1131 will hit the flow blocking wall at a high flow rate after being limited by the water passing hole 121, so that the water vapor is fully separated, and the water vapor separation is more thorough. The separated water is discharged from the water outlet hole 1133, and the separated water vapor is discharged from the air outlet hole A 1141. First, the flow is limited by the water passing hole 121 to increase the flow rate, and then the flow is blocked by the flow blocking wall, which makes the water vapor separation more thorough.

[0044] Further, as shown in Figure 8 In order to make the water flow out of the water passing hole 121 hit the flow blocking wall, the flow rate v1 of the water flow out of the water passing hole 121 satisfies the following relationship:

[0045] v1 = Q / S, wherein v1 is the flow rate of the water flow out of the water passing hole 121, Q is the volume flow rate of the water flow in the water passing cavity 113, and S is the cross-sectional area of the water passing hole 121;

[0046] v2 = X / t, wherein v2 is the minimum flow rate of the water flow passing through the water passing hole 121 that can impact the flow blocking wall, X is the distance between the water passing hole 121 and the flow blocking wall along the water outlet direction of the water passing hole 121, and t satisfies Y is the distance between the center of the water passing hole 121 and the bottom edge of the flow blocking wall in the longitudinal direction;

[0047] And, v1 is not less than v2.

[0048] When the water nozzle assembly 10 is finished, the above S, X, and Y are fixed values, and then the volume flow rate Q of the water flow in the water passing cavity 113 can be controlled so that v1 is not less than v2.

[0049] In some embodiments, the radius of the water passing hole 121 is less than 11.175 mm. This makes it easier to control the flow rate of the water flow passing through the water passing hole 121 to be not less than v2.

[0050] Specifically, in some embodiments, the flow blocking wall is a cavity wall of the water passing cavity 113. It can be understood that the water outlet direction of the water passing hole 121 is towards a certain part of the cavity wall of the water passing cavity 113. Thus, the water flow with a raised flow rate limited by the flow limiting piece 12 can impact on this part of the cavity wall. After the impact, the water and water vapor that are sufficiently separated continue to flow along the water passing cavity 113, and finally the water is discharged from the water outlet hole 1133, and the separated water vapor is discharged from the air outlet hole A1141.

[0051] Alternatively, in other embodiments, as shown in Figures 1 to 10 the flow blocking wall is a flow blocking piece 13 arranged in the water passing cavity 113. The flow limiting piece 12 and the flow blocking piece 13 are arranged in sequence in the flow direction of the water flow in the water passing cavity 113. As shown in Figure 8 the flow blocking piece 13 has a water passing gap 131 between the flow blocking piece 13 and the cavity wall of the water passing cavity 113. The air passing hole 1151 is located downstream of the flow blocking piece 13.

[0052] After the high-speed water vapor mixed fluid passing through the water passing hole 121 impacts on the flow blocking piece 13, both the liquid water and the water vapor can flow forward from the water passing gap 131.

[0053] Specifically, as shown in Figure 8As shown, in one embodiment, the water passage gap 131 is formed between the baffle 13 and the bottom wall of the water passage cavity 113. After the water vapor mixture that impacts the baffle 13 at high speed undergoes water vapor separation, the liquid water mainly flows through the bottom of the baffle 13 and flows downstream to the drain hole 1133.

[0054] Furthermore, such as Figure 8 As shown, the portion of the bottom wall of the water passage cavity 113 located between the flow-blocking member 13 and the drain hole 1133 is a guide wall 1121. In other words, the bottom wall of the water passage cavity 113 includes the guide wall 1121, which is located between the flow-blocking member 13 and the drain hole 1133. The height of the drain hole 1133 is lower than the height of the water passage hole 121. The guide wall 1121 gradually slopes downwards from the water passage hole 121 to the drain hole 1133. The liquid water obtained after water vapor separation flows rapidly along the guide wall 1121 to the drain hole 1133.

[0055] Furthermore, in one embodiment, such as Figure 8 As shown, the height of the air passage 1151 is not lower than the height of the water passage gap 131, so that the separated liquid water will not enter the ventilation chamber A114 from the air passage 1151, while the separated water vapor can enter the ventilation chamber A114 normally.

[0056] Specifically, such as Figure 8 As shown, except for the water passage gap 131 between the baffle 13 and the bottom wall of the water passage cavity 113, the other parts of the baffle 13 are connected to the cavity wall of the water passage cavity 113. The bottom edge of the baffle 13 is not higher than the lowest point of the air passage hole 1151.

[0057] Furthermore, such as Figure 5 As shown, in one embodiment, the cross-sectional area of ​​the water passage 121 is smaller than the cross-sectional area of ​​other parts of the water passage cavity 113. Here, the cross-section of other parts of the water passage cavity 113 refers to the cross-section perpendicular to the direction of water flow.

[0058] Furthermore, in one embodiment, such as Figures 1 to 9 As shown, the exhaust direction of the vent A1141 and the drainage direction of the drain hole 1133 are both downward. After the water tap assembly 10 is assembled into the water dispenser, both the vent A1141 and the drain hole 1133 are located outside the water dispenser body.

[0059] Furthermore, such as Figure 8 and Figure 9As shown, the water nozzle body 11 comprises a partition 115 separating the water passage cavity 113 and the air passage cavity A 114, the partition 115 is arranged along a direction parallel to the air exhaust direction of the air exhaust hole A 1141, and the air passage hole 1151 is formed at the top end of the partition 115. The separated water vapor floats up, enters the air passage cavity A 114 from the air passage hole 1151 at the top end of the partition 115, and then is exhausted from the air exhaust hole A 1141.

[0060] Further, as shown in the embodiment, the water nozzle body 11 further comprises an auxiliary cavity 116 separated from the water passage cavity 113 and the air passage cavity A 114. Figures 1 to 7 The auxiliary cavity 116 occupies part of the space in the water nozzle body 11, thereby reducing the volume of the water passage cavity 113, reducing the pressure in the water passage cavity 113, and based on the presence of the water passage hole 121, using the water's own tension to enable the water to stop flowing immediately when the user finishes taking water, achieving the effect of instantaneous stop.

[0061] Specifically, as shown in the embodiments, Figure 6 and Figure 7 The air exhaust hole A 1141 and the water exhaust hole 1133 are arranged in sequence in the transverse direction, and the auxiliary cavity 116 and the water passage cavity 113 are arranged in sequence in the transverse direction. The transverse width m of the portion of the water passage cavity 113 close to the water exhaust hole 1133 is smaller than the transverse width M of the portion of the water nozzle body 11 provided with the water exhaust hole 1133 and the air exhaust hole A 1141.

[0062] Further specifically, in an embodiment, as shown in the embodiments, Figure 6 and Figure 7 The portion of the water nozzle body 11 separated between the auxiliary cavity 116 and the air passage cavity A 114 is a first partition rib 1161, the first partition rib 1161 is arranged in the transverse direction, the air passage cavity A 114 is located on the front side of the first partition rib 1161, and the auxiliary cavity 116 is located on the rear side of the first partition rib 1161.

[0063] The auxiliary cavity 116 is located right behind the air cavity A 114. In other words, in order to make the molding process more simple, the water nozzle body 11 is divided into a front part and a rear part in the front-rear direction. The presence of the air inlet hole 1171, the first water inlet 1131 and the second water inlet 1132 makes the lateral width of the rear part larger than that of the front part. However, the lateral width of the front part is consistent in the front-rear direction, and the size of the lateral width of the front part is mainly affected by the air outlet hole A 1141, the air outlet hole B 1172 and the water outlet hole 1133. In order to reduce the volume of the water cavity 113, the auxiliary cavity 116 is added to occupy the space in the water nozzle body 11.

[0064] Specifically, as shown in Figure 6 and Figure 7 The part of the water nozzle body 11 that is separated between the auxiliary cavity 116 and the water cavity 113 is the second separation rib 1162.

[0065] Further, in one embodiment, F1 = a x L, where a is the surface tension coefficient of the liquid in the water cavity 113, and L = π x D, where D is the diameter of the water passing hole 121;

[0066] F2 = P x S, where P is the pressure at the water passing hole 121, P = p x g x h, where h is the vertical distance from the upper surface of the liquid in the water cavity 113 to the center of the water passing hole 121, and S is the cross-sectional area of the water passing hole 121, S = π x r 2 , where r is the radius of the water passing hole 121;

[0067] And, F1 is greater than F2.

[0068] F1 represents the size of the surface tension that the liquid in the water cavity 113 needs to overcome when passing through the water passing hole 121, and F2 represents the size of the pressure that the liquid is subjected to at the water passing hole 121 due to the pressure. When water taking is stopped, based on F1 being greater than F2, the liquid in the water cavity 113 will not continue to flow through the water passing hole 121, thereby achieving the effect of sudden stop.

[0069] It should be noted that the vertical distance h from the upper surface of the water in the water cavity 113 to the center of the water passing hole 121 is the distance from the center of the inlet of the water passing hole 121 to the upper surface of the liquid in the longitudinal direction. When the central axis of the water passing hole 121 is arranged in the horizontal direction, h is the distance between the central axis of the water passing hole 121 and the upper surface of the liquid in the water cavity 113.

[0070] Specifically, in some embodiments, the radius of the water passing hole 121 is less than 9.9 mm. In order to achieve the effect of sudden stop after the user finishes taking water, the water nozzle assembly 10.

[0071] Furthermore, such as Figures 1 to 5 As shown, in one embodiment, the faucet body 11 is further provided with a second water inlet 1132 communicating with the water passage cavity 113. In actual use, the first water inlet 1131 is mainly used to introduce high-temperature water, such as boiling water; Figure 10 As shown, the second water inlet 1132 is mainly used to introduce room temperature water, such as cooled boiled water.

[0072] Specifically, such as Figure 8 and Figure 10 As shown, the second inlet 1132 is arranged side by side with the first inlet 1131. In... Figures 1 to 5 At the angle shown, the second inlet 1132 and the first inlet 1131 are arranged side by side in the transverse direction.

[0073] Furthermore, such as Figures 1 to 7 As shown, in one embodiment, the water outlet direction of the first water inlet 1131, the water outlet direction of the second water inlet 1132, and the water inlet direction of the through hole 121 are parallel. A plane perpendicular to the water outlet direction of the first water inlet 1131 is a virtual projection plane, and the projection of the through hole 121 on this virtual projection plane is located on the side where the projection of the second water inlet 1132 on the virtual projection plane is furthest from the projection of the first water inlet 1131 on the virtual projection plane.

[0074] Fluid entering from the first inlet 1131 and the second inlet 1132 will first impact the cavity wall of the water passage 113, and then change the flow direction to flow to the water passage 121.

[0075] like Figures 2 to 7 As shown, the second dividing rib 1162 includes a laterally extending dividing rib A1163 and a dividing rib B1164 extending in the front-back direction. The first water inlet 1131 and the second water inlet 1132 both face the dividing rib A1163, and the dividing rib B1164 is located on one side of the flow restrictor 12.

[0076] Furthermore, in one embodiment, such as Figures 1 to 7 As shown, the water nozzle body 11 is also provided with a venting chamber B117, and the water nozzle body 11 is provided with an air inlet 1171 and an exhaust port B1172 that are both connected to the venting chamber B117.

[0077] like Figure 11 As shown, when water is added to the water tank 21 of the water dispenser, the air originally contained in the water tank 21 needs to be expelled. The air can first enter the venting chamber B117 and then be discharged from the exhaust port B1172.

[0078] Specifically, as shown in Figure 6 and Figure 7 in an embodiment, the water passage cavity 113 is located between the air passage cavity B 117 and the auxiliary cavity 116.

[0079] Further specifically, in an embodiment, as shown in Figure 7 and Figure 9 the air outlet hole A 1141, the water outlet hole 1133 and the air outlet hole B 1172 are arranged in parallel in the transverse direction.

[0080] Further, as shown in Figure 11 in an embodiment, a stopper 14 is arranged in the air passage cavity B 117, the bottom of the stopper 14 is connected with the cavity wall of the air passage cavity B 117, and the stopper 14 is arranged in spaced relation with the top wall of the air passage cavity B 117. Thus, when the air in the water tank 21 enters the air passage cavity B 117, if some water vapor is brought in, the condensed liquid water will be intercepted by the stopper 14, avoiding the phenomenon of water dripping at the air outlet hole B 1172.

[0081] Further, in an embodiment, as shown in Figure 1 and Figure 2 the water nozzle body 11 is divided into an upper cover body 111 and a lower cover body 112 by a virtual cross section parallel to the horizontal plane.

[0082] The flow blocking member 13 is connected with the upper cover body 111, the flow blocking member 13 is spaced from the bottom wall of the lower cover body 112 to form the water passing gap 131, and the water passing hole 121 is located on the upper side of the virtual cross section.

[0083] Thus, the upper cover body 111 and the lower cover body 112 can be separately processed and formed and then assembled together.

[0084] Specifically, in an embodiment, the upper cover body 111 and the lower cover body 112 are welded.

[0085] Alternatively, in other embodiments, the upper cover body 111 and the lower cover body 112 can also be connected in other ways.

[0086] It should be noted that the components included in the water nozzle assembly 10 are divided into upper and lower parts by the virtual cross section as long as they pass through the virtual cross section, and are fixed with the upper cover body 111 and the lower cover body 112, respectively.

[0087] Further, in another embodiment, a water vapor separation mechanism is provided, which includes the above-mentioned water nozzle assembly 10. Thus, the separation effect of the water vapor separation mechanism is improved, so that liquid water and water vapor can be separated more completely.

[0088] Further, in yet another embodiment, there is provided a water dispenser 20 comprising the water nozzle assembly 10 as described above.

[0089] By employing the water nozzle assembly 10 as described in any of the above embodiments, the water vapor separation effect can be improved, and the scalding situation can be avoided when taking water from the drain hole 1133 of the water dispenser.

[0090] Specifically, as shown in FIG. 1, in one embodiment, the water dispenser 20 further comprises a water tank 21 and a heating member 22. The water tank 21 is provided with a water storage cavity. The water tank 21 is provided with a water pumping port 211 which is in communication with the water storage cavity. The heating member 22 is provided with a heating passage. An inlet of the heating passage is in communication with the water pumping port 211. An outlet of the heating passage is in communication with the first water inlet 1131. Figure 12 Figure 13 The purified water in the water tank 21 can be heated when flowing through the heating passage. The heated water vapor mixed fluid can enter the water passage cavity 113 from the first water inlet 1131. After water vapor separation, the liquid water is discharged from the drain hole 1133, and the water vapor is discharged from the exhaust hole A1141.

[0091] Further, in one embodiment, the second water inlet 1132 is in communication with the water pumping port 211 of the water tank 21, so that the purified water in the water tank 21 can directly enter the water passage cavity 113 from the second water inlet 1132, and then be discharged from the drain hole 1133.

[0092] Specifically, in one embodiment, a cold water passage (not shown in the figure) is in communication between the second water inlet 1132 and the water pumping port 211.
