The present invention proposes a water outlet nozzle 100, which is suitable for a water purifying device, and the water purifying device may be a water dispenser or a water purifying dispenser, which is not limited in particular.
In the embodiment of the present invention, as shown in fig. 1 to 4, the water outlet nozzle 100 includes a housing 10, an air outlet pipe 40, a water inlet pipe 20 and a water outlet pipe 30; the housing 10 has a cavity 13; the exhaust pipe 40 is connected to the housing 10 and communicates with the cavity 13; the water inlet pipe 20 is connected with the shell 10 and is communicated with the cavity 13; the water outlet pipe 30 is connected with the bottom of the shell 10 and is communicated with the cavity 13, the water outlet pipe 30 comprises a diversion section 31, an upper end point and a lower end point which are not on the same vertical line are arranged on a diameter section of the water outlet pipe 30, a fastest descent line is arranged between the upper end point and the lower end point, any point is arranged on the fastest descent line, and a line section of the fastest descent line between the upper end point and the any point coincides with an intersection line of the diameter section and the inner wall surface of the diversion section 31.
Specifically, the housing 10 may be provided in a box shape, or may be provided in other shapes, which is not particularly limited. The housing 10 is used to mount the water outlet nozzle 100 to the water purifying apparatus, and provides a space for water supply flow. The water inlet pipe 20 may be a circular pipe or a square pipe, and is not particularly limited. In this embodiment, a water inlet pipe 20 is connected to the top of the housing 10. In other embodiments, inlet tube 20 may be connected to the bottom or side of housing 10 without undue limitation. The water inlet pipe 20 is used for being connected with a water path in the water purifying device so that water flows into the cavity 13 of the housing 10. The water outlet pipe 30 may be a circular pipe or a square pipe, which is not particularly limited. The water outlet pipe 30 is used for water in the shell 10 to flow out, namely, water of the water purifying device flows out from the water outlet pipe 30 of the water outlet nozzle 100. In this embodiment, the water outlet pipe 30 extends in the vertical direction, so that the user can take water conveniently.
The diameter section of the water outlet pipe 30 is a plane passing through the axis of the water outlet pipe 30 and extending in the vertical direction. Two endpoints which are not on the same vertical line are arranged on the diameter section of the water outlet pipe 30, one is an upper endpoint, and the other is a lower endpoint, namely, the upper endpoint is not in the vertical direction of the lower endpoint, and the upper endpoint is obliquely above the lower endpoint. The fastest drop line is the curve that takes the shortest time for a particle with zero initial velocity to move from the upper endpoint to the lower endpoint under the force of gravity alone. Any point refers to any point on the maximum descent line except the upper end point, and any point may be a bisection point, a trisection point, a lower end point, or the like of the maximum descent line, which is not particularly limited.
It is to be understood that the flow guiding section 31 is a section of the water outlet pipe 30, and the flow guiding section 31 may be disposed at an upper portion of the water outlet pipe 30 or may be disposed at a middle portion of the water outlet pipe 30, which is not limited in particular. The inner wall surface of the guide section 31 coincides with an annular curved surface formed by one rotation of the line segment between the upper end point of the maximum speed drop line and any point around the axis of the water outlet pipe 30, that is, the upper end point of the maximum speed drop line is on the periphery of the inlet of the inner wall surface of the guide section 31, and any point is on the periphery of the outlet of the inner wall surface of the guide section 31. By this arrangement, the time taken for the water flow to flow from the inlet of the inducer 31 to the outlet of the inducer 31 can be minimized, i.e., the flow rate of the water flow is increased. The inner wall surface of the guide section 31 is curved from the inside of the water outlet pipe 30 to the outside of the water outlet pipe 30 to form a concave surface, so that the water flowing through the guide section 31 can flow along the inner wall surface of the guide section 31. The inner wall surface of the guiding section 31 gradually contracts from the inlet of the guiding section 31 to the outlet of the guiding section 31, so that the flow speed of the flowing water flow is improved, the flowing water flow is prevented from drifting, and the water flow is ensured to flow out in a bundle shape (as shown in the right graph in fig. 12, the right graph in fig. 13, the right graph in fig. 14 and the right graph in fig. 15).
As shown in fig. 3 and 4, the design method of the diversion section 31 is as follows: determining a point on a tangential plane of the water outlet pipe 30 as an upper end point (shown in a of fig. 4), determining another point which is not in a vertical direction of the upper end point as a lower end point (shown in b of fig. 4), taking the upper end point as an origin, establishing a plane rectangular coordinate system, setting a rolling circle, setting a fixed point (shown in c of the figure) on the rolling circle, enabling the rolling circle to roll on an x axis, enabling the upper end point and the lower end point to be on a motion track of the fixed point, enabling the motion track of the fixed point to be a fastest descent line, and finally obtaining the fastest descent line through a standard parameter equation of the fastest descent line, wherein the standard parameter equation of the fastest descent line is as follows: x=r (θ -sin θ), y=r (1-cos θ). Wherein r is the radius of the round sphere, and θ is the angle between the speed direction of the fixed point and the y axis. It is understood that the size parameters of the water outlet nozzle 100 of different water purifying apparatuses may be different, so that when designing the flow guiding section 31, the position of the upper end point, the position of the lower end point and the radius of the rounding may be adjusted according to the structure of the water outlet nozzle 100, for example, when the length of the water outlet pipe 30 is longer, the length of the flow guiding section 31 may be correspondingly designed longer, which is not limited specifically.
According to the technical scheme, the diversion section 31 of the water outlet pipe 30 adopts the design of the fastest descent line so as to improve the flow velocity of water flowing out of the water outlet pipe 30, thereby avoiding the flowing water from drifting and further improving the use experience of users.
It can be appreciated that when a user needs to use boiling water, the water purifying device outputs boiling water, and the boiling water generates a large amount of steam, and the steam and the boiling water are sprayed out of the water outlet nozzle 100 at the same time, so that the boiling water is easy to splash under the action of the air flow of the steam, thereby scalding the user.
In this embodiment, the exhaust pipe 40 is communicated with the cavity 13, so that when the boiling water is introduced into the water outlet nozzle 100, the steam generated by the boiling water can be discharged through the exhaust pipe 40, so as to avoid the steam being sprayed out of the water outlet pipe 30 along with the boiling water, and scald the user.
In an embodiment, the arbitrary point is a midpoint of the fastest drop line.
It will be appreciated that the slope of the line of maximum speed reduction from the upper end point to the lower end point is gradually reduced, i.e. the component of gravity force applied to the particles is gradually reduced, and the acceleration of the particles is gradually reduced, and it is known that the velocity of the particles in the upper half of the line of maximum speed reduction increases relatively fast compared with the velocity in the lower half, so that any point takes the midpoint (bisector) of the line of maximum speed reduction, so that the particles acquire a relatively high velocity in a relatively short time, and the water flow flowing through the diversion section 31 acquires a relatively high velocity in a short time, thereby reducing the length of the diversion section 31 and facilitating the compact design of the nozzle 100.
In this embodiment, the inner wall surface of the guide section 31 coincides with an annular curved surface formed by one rotation of a line segment between the upper end point and the middle point of the maximum speed drop line around the axis of the water outlet pipe 30.
In an embodiment, as shown in fig. 2 and 3, the water outlet pipe 30 further includes a water outlet section 32, the flow guiding section 31 is connected to the bottom of the housing 10, and the flow guiding section 31 communicates with the cavity 13 and the water outlet section 32.
In this embodiment, the diversion section 31 is disposed at the upper section of the water outlet pipe 30, the bottom of the housing 10 is provided with a water outlet communicated with the cavity 13, the water outlet is communicated with the inlet of the diversion section 31, the inlet of the water outlet section 32 is communicated with the outlet of the diversion section 31, the water outlet section 32 is in a circular tube shape, and the inner diameter of the water outlet section 32 is equal in diameter in the axial direction. The water flow from the cavity 13 flows into the diversion section 31 to increase the flow rate, and then flows out of the water outlet section 32 and out of the water nozzle 100.
In other embodiments, the inner diameter of the outlet section 32 may be tapered in the axial direction to increase the flow rate of the outgoing water flow and prevent the water flow from drifting.
In one embodiment, as shown in fig. 2 and 5, the housing 10 includes a housing main body 11 and an upper cover 12, and the water outlet pipe 30 is connected to the bottom of the housing main body 11; the upper cover 12 is covered on the top of the shell main body 11, and the water inlet pipe 20 is connected to the top of the upper cover 12.
Specifically, the top of the housing body 11 is provided with an opening, and the upper cover 12 is covered at the opening of the housing body 11 to form a cavity 13. The case main body 11 and the upper cover 12 are fixed by hot melt, or by adhesive, or by integral connection, or by bolting, which is not particularly limited. The water outlet pipe 30 is integrally connected with the bottom of the housing main body 11, or is thermally fused or bolted, which is not particularly limited. The water inlet pipe 20 is integrally connected with the top of the upper cover 12, or is thermally fused or bolted, which is not particularly limited.
In this embodiment, the exhaust pipe 40 is connected to the upper cover 12, and the density of the steam is less than that of the air, so that the steam can flow upwards, and the exhaust pipe 40 is arranged on the upper cover 12 to facilitate the steam discharge, so as to realize the split flow of the boiling water and the steam, thereby effectively avoiding the steam from being sprayed out from the water outlet pipe 30 along with the boiling water and scalding the user.
In one embodiment, as shown in fig. 2, a buffer structure is disposed in the housing 10, and the buffer structure is located between the water inlet pipe 20 and the water outlet pipe 30.
It will be appreciated that the flow rate of the water flowing into inlet tube 20 may be unstable, stumbling and slow, which may tend to result in unstable water output from spout 100. In this embodiment, a buffer structure is disposed between the water outlet pipe 30 and the water inlet pipe 20 to reduce the flow velocity of the water flowing in from the water inlet pipe 20, so that the water flowing through the buffer structure is stable, and the water outlet stability of the water outlet nozzle 100 is ensured.
In one embodiment, as shown in fig. 2, 5 and 8, the buffer structure is a baffle 50 disposed in the housing 10, and a plurality of through holes 51 are formed in the baffle 50.
Specifically, the baffle 50 blocks the water flow flowing into the casing 10 from the water inlet pipe 20, and the water flow flows out of the baffle 50 through the through holes 51 to buffer and throttle the water flow, as shown in the right diagram of fig. 10 and the right diagram of fig. 11, so as to reduce the peak value of the flow velocity of the water flow flowing through the baffle 50, reduce the temperature drop of the cold core, make the sudden expansion area pressure and velocity distribution of the water flow flowing through the baffle 50 uniform, further ensure the stable flow field of the water flow flowing through the baffle 50, reduce the generation of gas-liquid mixture, and effectively improve the problems of water flow drift and spraying when the water outlet nozzle 100 discharges water. For example, when the water outlet nozzle 100 is filled with boiling water, the generation of a mixture of the boiling water and steam is reduced, and the formation of spray of the boiling water under the action of air flow of the steam can be effectively prevented, so that a user is prevented from being scalded when taking water, and the safety of the water purifying equipment is further improved.
In the present embodiment, the baffle 50 is integrally provided with the upper cover 12. In other embodiments, the baffle 50 may be heat staked, or bolted, to the upper cover 12; the baffle 50 may be integrally connected to the case main body 11, or may be thermally fused or bolted, which is not particularly limited.
In this embodiment, the baffle 50 is disposed orthogonal to the water flow direction, i.e. the normal direction of the baffle 50 is disposed parallel to the water flow direction, so as to ensure the buffering effect of the baffle 50 on the water flowing out of the water inlet pipe 20. In other embodiments, the baffle 50 may be disposed obliquely to the water flow direction, which is not particularly limited.
In this embodiment, the through hole 51 is a circular hole, which is convenient for hole making. In other embodiments, the through hole 51 may be a polygonal hole, or an irregularly shaped hole, which is not particularly limited.
In this embodiment, the plurality of through holes 51 are arranged in an array, the array is a square matrix, the intervals between the adjacent through holes 51 in the vertical direction are equal, and the intervals between the adjacent through holes 51 in the horizontal direction are equal, so that the pressure and the speed of the sudden expansion area of the water flow flowing through the baffle 50 are uniformly distributed, and the flow field of the water flow flowing through the baffle 50 is ensured to be stable. In other embodiments, the plurality of through holes 51 may be arranged in an elliptical shape or a diamond shape, which is not limited thereto.
In one embodiment, as shown in fig. 2, 8 and 9, the edge of the baffle 50 connected to the inner bottom wall of the housing 10 is provided with a plurality of notches 52.
In this embodiment, the side edge of the baffle 50 abuts against the inner side wall of the case main body 11, and the bottom edge of the baffle 50 abuts against the inner bottom wall of the case main body 11. It will be appreciated that there may be a gap between the baffle 50 and the inner wall of the housing body 11, and the notch 52 cooperates with the inner bottom wall of the housing body 11 to form a water hole, so as to avoid uneven slit flow of water flowing through the gap after the housing body 11 is assembled with the upper cover 12, which causes the water nozzle 100 to emit abnormal noise.
In one embodiment, as shown in fig. 8, the notch 52 is arranged in a semicircular shape. In this embodiment, the projection of the notch 52 in the horizontal direction is semicircular, and the notch 52 cooperates with the inner bottom wall of the case main body 11 to form a semicircular water passing hole.
In one embodiment, as shown in fig. 9, the notch 52 is disposed in a long strip shape.
In the present embodiment, the notches 52 are provided extending from the bottom edge of the baffle 50 in a direction away from the case main body 11, the adjacent notches 52 are unequal in length, the notches 52 are divided into the shortage ports 52 and the long notches 52, and the shortage ports 52 and the long notches 52 are alternately provided.
