Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Referring to fig. 1 to 8, the present application provides a nozzle 10 including a housing 100, an adjustment slider 200, and a driving assembly 300. The housing 100 is provided with a water inlet 111, a water inlet channel 112, an adjusting hole 113 and a water outlet 114, which are sequentially connected, and the water outlet 114 can be considered as a water outlet formed by the adjusting hole 113 penetrating through the housing 100, that is, the water outlet 114 is directly connected with the external environment and used for emitting water. The adjusting slider 200 is disposed in the adjusting hole 113, the swirl chamber 220 is disposed on the housing 100 or the adjusting slider 200, and the swirl chamber 220 communicates with the water jet 114 and serves to rotate the water flowing therethrough. The driving component 300 is abutted against one end of the adjusting slider 200, and the adjusting slider 200 is configured to move in the adjusting hole 113 under the abutment of the driving component 300 or under the water pressure of the water inlet channel 112, so as to adjust the flow rate of the water flowing from the adjusting hole 113 through the vortex chamber 220, thereby enabling the water jet 114 to emit different water types.

Specifically, in the embodiment shown in fig. 5, the adjusting slider 200 includes a cylinder 210 and a swirl chamber 220, the cylinder 210 is substantially cylindrical, the swirl chamber 220 is disposed at one end of the cylinder 210 near the water jet 114, and the swirl chamber 220 can be regarded as being formed by a recess at one end of the cylinder 210. The swirl chamber 220 is directed toward the water jet 114 and communicates directly with the water jet 114, and the swirl chamber 220 may impart a rotational flow to the water passing therethrough. The driving component 300 is abutted against the other end of the column 210 of the adjusting slide block 200, and the adjusting slide block 200 is arranged to be capable of moving in the adjusting hole 113 under the abutment of the driving component 300 so as to adjust the flow rate of water flowing from the adjusting hole 113 through the swirl chamber 220, thereby enabling the water jet 114 to emit different water types.

It will be appreciated that in other embodiments, the swirl chamber 220 may be selectively opened in the housing 100, i.e. the subject application is directed to controlling the flow rate of the water flowing through the swirl chamber 220, and the specific embodiments listed herein are not intended to limit the specific location of the swirl chamber 220.

In the sprinkler 10, the cylinder 210 of the adjusting slider 200 is provided with a swirl chamber 220 at one end close to the water outlet 114, and the adjusting slider 200 can move in the adjusting hole 113 to adjust the flow rate of the water flowing through the swirl chamber 220. When the flow rate of the water flowing through the swirl chamber 220 reaches a maximum value, that is, when the water supplied to the adjustment hole 113 from the water inlet passage 112 flows through the swirl chamber 220 in its entirety, the rotation speed of the water flow also reaches a maximum value, and at this time, the water sprayed from the water spray port 114 is dispersed by the centrifugal force and the coverage area is maximized.

When a part of the water in the adjusting hole 113 flows through the swirl chamber 220, another part of the water directly flows from the adjusting hole 113 to the water jet 114. Since only a part of the water flow rotates by the swirl chamber 220, the overall rotational speed of the water flow is reduced, and the coverage area of the water sprayed from the water spray 114 is reduced when the water is dispersed by the centrifugal force.

When the flow rate of the water flowing through the swirl chamber 220 reaches the minimum value, that is, when the water in the adjustment hole 113 is directly sprayed from the water spray 114 without preferentially passing through the swirl chamber 220, the water flow does not substantially rotate at this time, and thus the water type sprayed from the swirl chamber is substantially cylindrical and the coverage area is minimum.

In short, the nozzle 10 of the present application skillfully controls the flow rate of the water flowing through the swirl chamber 220 by arranging the adjusting slider 200 in the adjusting hole 113, thereby realizing the full-range control that the water type ejected from the water jet 114 gradually changes from the maximum value to the minimum value of the coverage area, i.e. a single water jet 114 can eject multiple water types. In the process of realizing the switching of the spray washing modes, the water jet can not be cut off, the gradual change of the spray water type is realized, and the user experience effect is improved.

Referring to fig. 2 and 3, in an embodiment, the water outlet 114 may be considered as the adjusting hole 113 formed through the housing 100, and the aperture of the adjusting hole 113 gradually shrinks in a direction close to the water outlet 114, that is, the aperture of the water outlet 114 is larger than the aperture of the adjusting hole 113. The structural arrangement can ensure that the water flow speed of the water flow in the adjusting hole 113 is gradually increased in the process of flowing to the water spraying opening 114, namely, the initial speed of the water flow emitted by the water spraying opening 114 is increased, so that the range of the water flow is increased.

Referring to fig. 4 and 5, in some embodiments, the circumferential surface of the swirl chamber 220 is provided with a water inlet groove 221 communicated with the swirl chamber 220, and the adjusting hole 113 guides water flow into the swirl chamber 220 through the water inlet groove 221. The dotted line with an arrow in fig. 4 may be considered as a rough schematic line of the water inlet direction of the water inlet groove 221, which is away from the center of the vortex chamber 220, and because of the structural arrangement, the water flow flowing through the water inlet groove 221 does not directly face the center of the vortex chamber 220, i.e., the water flow deviates from the center of the vortex chamber 220, thereby enabling the water flow to be diverted and rotated in the circumferential direction of the vortex chamber 220 under the restriction of the inner wall of the vortex chamber 220. Further, in the embodiment as shown in fig. 4, the inner ring of the swirl chamber 220 is substantially circular, and the water inlet direction of the water inlet groove 221 is tangential to the inner wall of the swirl chamber 220.

Specifically, as shown in fig. 4 and 5, in some embodiments, the water inlet groove 221 may be provided in plurality, and the plurality of water inlet grooves 221 are wound on the circumferential surface of the swirl chamber 220 at intervals in the circumferential direction of the swirl chamber 220. With such a structure, it can be considered that the water inlet directions of the water inlet grooves 221 do not collide with each other, that is, the directions of the multiple water flows flowing through the vortex chamber 220 from the water inlet grooves 221 all rotate in the same direction, that is, the multiple water flows all rotate in a clockwise direction or a counterclockwise direction. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

More specifically, as shown in fig. 4 and 5, in some embodiments, a plurality of flow guiding ribs 211 are protruded from an outer circumferential surface of the cylinder 210 of the adjusting slider 200, the plurality of flow guiding ribs 211 are arranged at equal intervals along a circumferential direction of the cylinder 210, and the plurality of flow guiding ribs 211 extend along an axial direction of the cylinder 210. The shape of each of the flow guiding ribs 211 is the same, the size is equal, and the flow guiding ribs are substantially plate-shaped. The guiding gutter has been formed between adjacent water conservancy diversion muscle 211, and such structure setting can make water flow more smoothly on the one hand, and on the other hand water conservancy diversion muscle 211 can also support with the pore wall of adjusting hole 113, prevents that cylinder 210 and swirl chamber 220 from producing when adjusting hole 113's axial displacement and rocking, has promoted the motion stability of adjusting slider 200, produces the skew when avoiding rivers from spout 114.

Further, as shown in fig. 2, 5, 6, 7 and 8, in some embodiments, the adjusting slider 200 is configured to move along the axial direction of the adjusting hole 113 to approach or separate from the water jet 114 under the driving of the driving assembly 300.

As shown in fig. 6, when the water inlet channel 112 delivers water to the adjusting hole 113 and the water inlet channel 112 is filled with water, the cylinder 210 of the adjusting slider 200 can approach the water jet 114 under the action of water pressure and make the top of the vortex chamber 220 tightly contact with the hole wall of the adjusting hole 113. It can be understood that, at this time, the water in the adjusting hole 113 can only flow through the swirl chamber 220 through the water inlet groove 221 and then be ejected from the water jet 114, that is, the water flow in the adjusting hole 113 can all flow through the swirl chamber 220 from the water inlet groove 221, the flow rate of the water flow flowing through the swirl chamber 220 reaches the maximum value, the rotation speed of the water flow also reaches the maximum value, and the water ejected from the water jet 114 is dispersed under the action of centrifugal force, so as to generate the softest large-cone-angle water jet type with the largest cleaning area.

As shown in fig. 7, when there is a gap between the top of the swirl chamber 220 of the adjusting slider 200 and the wall of the adjusting hole 113, a part of the water in the adjusting hole 113 directly flows from the outer circumferential surface of the cylinder 210 to the water jet 114, and another part of the water in the adjusting hole 113 flows from the water inlet groove 221, passes through the swirl chamber 220, accelerates rotation, and then is ejected from the water jet 114. In other words, only a part of the water flow rotates by the swirl chamber 220, the rotational speed of the entire water flow is reduced, and the water ejected from the water ejection port 114 forms a small cone angle water ejection type.

As shown in fig. 8, when the adjusting slider 200 is driven by the driving assembly 300 to be away from the water outlet 114, the water flow in the adjusting hole 113 can preferentially flow from the outer circumferential surface of the cylinder 210 to the water outlet 114 directly, i.e. the water flow does not substantially pass through the swirl chamber 220, and the water flow is directly ejected from the water outlet 114 without rotating, so as to generate a thin cylindrical water jet.

In short, the spray water type is sprayed the water type by big cone angle and is gradually become little cone angle spray water type, sprays the water type by little cone angle and gradually becomes thin cylindrical spray water type again, can not appear breaking off, has realized the gradual change of spray water type for spray water type becomes the gradual change water type.

Referring to fig. 2 and 5, in some embodiments, the adjustment block 200 further includes an actuator arm 230 coupled to the post 210, the actuator arm 230 being located at an end of the post 210 that is distal from the swirl chamber 220.

As shown in fig. 9, the driving assembly 300 includes a driving shaft 310 and a cam 320, the driving shaft 310 is rotatably disposed through the housing 100, and the cam 320 is disposed on the driving shaft 310. The cam 320 is disposed to abut against the transmission arm 230 under the driving of the driving shaft 310 to move the cylinder 210 in the axial direction of the adjustment hole 113.

Specifically, in the embodiment shown in fig. 9, the cam 320 is provided with an arcuate limiting groove 321, the cross-sectional profile of the front end of the driving shaft 310 is matched with the cross-sectional profile of the limiting groove 321, and the front end of the driving shaft 310 extends into the limiting groove 321 to be fixed with the cam 320, so as to drive the cam 320 to rotate.

Further, in the embodiment shown in fig. 2 and 5, the driving arm 230 is connected to the outer circumferential surface of the cylinder 210 and is integrally formed with the cylinder 210, and the water inlet direction of the driving arm 230 is perpendicular to the axial direction of the cylinder 210.

Further, as shown in fig. 2 and 5, in some embodiments, the adjustment slider 200 further includes a contact 231, the contact 231 is protruded from an end of the transmission arm 230 away from the cylinder 210, and the contact 231 is used for making a frictional contact with the cam 320, that is, the cam 320 drives the transmission arm 230 by abutting against the contact 231. The contact 231 is any one of a spherical shape, a semi-spherical shape or a spherical cap, so that the cam 320 and the contact 231 realize rolling friction, and the abrasion is reduced.

Referring to fig. 2, in one embodiment, the housing 100 includes a first housing 110 and a second housing 120, the first housing 110 has an adjusting hole 113 and a water spraying hole 114, and the first housing 110 and the second housing 120 enclose a cavity for water inlet, i.e., a water inlet channel 112. Before the first housing 110 and the second housing 120 are fastened, the adjustment slider 200 is assembled, the cylinder 210 of the adjustment slider 200 is inserted into the adjustment hole 113, and the driving arm 230 is allowed to contact the cam 320 of the driving assembly 300. Thereafter, the second housing 120 is fastened to the first housing 110, and the housing 100 is sealed by ultrasonic welding, bonding, or the like, thereby preventing water leakage.

Specifically, as shown in fig. 2, in some embodiments, the second housing 120 is provided with a limiting protrusion 121 on a side facing the adjusting hole 113, and after the second housing 120 is fastened to the first housing 110, the limiting protrusion 121 is located just below the adjusting slider 200, i.e. at an end of the cylinder 210 of the adjusting slider 200 away from the water outlet 114. When the cam 320 drives the transmission arm 230 to press the cylinder 210 downward, the limiting protrusion 121 can limit the downward movement of the cylinder 210, so as to prevent the cylinder 210 of the adjustment slider 200 from coming out of the water outlet hole and affecting subsequent use.
