Technical Field

The invention relates to the technical field of intelligent bathrooms, in particular to a spray head, a spray gun, a toilet lid and an intelligent toilet.

Background

The existing intelligent closestool is provided with a plurality of nozzles on a spray gun, different nozzles spray cleaning water with different water types, and the nozzles are communicated with water inlet through different flow channels respectively. The spray gun realizes that the spray water is switched among a plurality of nozzles through the motor rotating reversing valve, thereby realizing the switching of different cleaning water types.

However, in the cleaning process of the spray gun of the traditional intelligent toilet, if the cleaning mode needs to be switched, the spray gun needs to stop the current function first, and after the reversing valve plate is switched into the required function and the residual cold water in the pipeline in the new mode is exhausted, the spray gun stretches out again to spray and clean the human body again, so that the waiting time of a user is long. In addition, after the cleaning mode is switched, the pressure and the temperature of the effluent are unstable, so that the user experience is poor.

Disclosure of Invention

In view of the above, it is necessary to provide a spray head, a spray gun, a toilet lid and an intelligent toilet.

The application relates to a spray head, which comprises:

the water inlet channel, the adjusting hole and the water spraying opening are sequentially communicated;

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, 2 and 7, the present application provides a nozzle 10 including a housing 100, an adjustment slider 200 and a driving member 300. The housing 100 is provided with a water inlet 111, a water inlet channel 112, an adjusting hole 113 and a water jet 114, which are sequentially communicated, that is, the water jet 114 is directly communicated with the external environment and is used for jetting water flow. The adjusting slider 200 is disposed in the adjusting hole 113, and the outer circumferential surface of the adjusting slider 200 is provided with a guide groove 212. A swirl chamber 220 is provided between the adjustment slider 200 and the housing 100, and the swirl chamber 220 communicates with the water jet 114 and serves to rotate the water flowing therethrough. As shown in fig. 2, the driver 300 is rotatably inserted into the housing 100, the driver 300 includes a main shaft portion 310 and an eccentric protrusion 320 provided on an end surface of the main shaft portion 310, the eccentric protrusion 320 is disposed offset from an axis of the main shaft portion 310, and the driver 30 can be considered as an eccentric shaft. The eccentric protrusion 320 is inserted into the guide groove 212 and is used to drive the adjusting slider 200 to move in the adjusting hole 113 along the axial direction of the adjusting hole 113, so as to adjust the flow rate of the water flowing through the swirl chamber 220, thereby enabling the water jet 114 to emit different water types.

Specifically, in the embodiment as shown in fig. 4, 5 and 6, the adjusting slider 200 includes a cylinder 210 and a vortex chamber 220, the cylinder 210 is substantially cylindrical, the outer circumferential surface of the cylinder 210 of the adjusting slider 200 is provided with a guide groove 212, the vortex chamber 220 is arranged at one end of the cylinder 210 close to the water jet 114, and the vortex chamber 220 can be considered 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.

It is understood that, in other embodiments, the swirl chamber 220 may be selectively opened on the housing 100, and the details of the swirl chamber 220 disposed on the housing 100 may refer to the structure of the swirl chamber 220 on the adjustment slider 200 mentioned in this application, which will not be described herein. In other words, the subject matter of the present application is to control the flow rate of the water flowing through the vortex chamber 220, and the specific embodiments listed herein are not intended to limit the specific location of the vortex chamber 220.

Referring to fig. 8 to 10, the eccentric protrusion 320 of the driving member 300 of the nozzle 10 is inserted into the guide groove 212 of the adjustment slider 200, and when the driving member 300 rotates, the eccentric protrusion 320 can drive the adjustment slider 200 to move by contacting the guide groove 212, so as 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 preferentially flows through the swirl chamber 220 and the other part of the water directly flows from the adjusting hole 113 to the water jet 114. Since only a part of the water flow is accelerated and rotated by the swirl chamber 220, the rotational speed of the whole 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 a minimum value, that is, when the water in the adjustment hole 113 is directly sprayed from the water spray 114 without passing through the swirl chamber 220, the water flow does not substantially rotate, and thus the water sprayed from the swirl chamber is substantially cylindrical and has a minimum coverage area.

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 mode, the water jet 114 does not break off, the continuous switching and stepless gradual change of the water jet type can be realized, and the user experience 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, i.e. the aperture of the water outlet 114 is larger than that 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 outer circumferential side 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 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, 5 and 7, in some embodiments, the outer circumferential surface of the cylinder 210 of the adjusting slider 200 is convexly provided with a plurality of guide ribs 211, the plurality of guide ribs 211 are arranged at equal intervals along the circumferential direction of the cylinder 210, and the plurality of guide ribs 211 extend along the axial direction of the cylinder 210. The guide ribs 211 are identical in shape and size, and are substantially plate-shaped. The guiding gutter has been formed between adjacent direction muscle 211, and such structure setting can make water flow more smoothly on the one hand, and on the other hand direction muscle 211 can also support with the pore wall of adjusting hole 113 counterbalance, 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 blowout.

As shown in fig. 4 and 7, in some embodiments, a limiting sliding groove 115 is formed on an inner circumferential surface of the adjusting hole 113, at least one guiding rib 211 extends into the limiting sliding groove 115, and the adjusting hole 113 is in limiting fit with the at least one guiding rib 211 through the limiting sliding groove 115 to limit a moving direction of the adjusting slider 200.

Specifically, in the embodiment shown in fig. 4 and 7, two guide ribs 211 are respectively located on two opposite sides of the outer circumferential surface of the cylinder 210 of the adjustment slider 200, and both the two guide ribs 211 are extended outward in the radial direction of the cylinder 210. The inner peripheral surface of the adjusting hole 113 is also provided with two limiting sliding grooves 115, and the two lengthened guide ribs 211 respectively extend into the two limiting sliding grooves 115 and are matched in shape and size. When the adjusting slide block 200 slides along the axial direction of the adjusting hole 113, the groove walls of the limiting slide grooves 115 on the two opposite sides of the adjusting slide block 200 can be abutted to the guide ribs 211, so that the movement direction of the adjusting slide block 200 is limited, the movement stability of the adjusting slide block 200 is improved, and lateral deviation is prevented from being generated during water spraying.

Referring to fig. 2, 6, 7, 8, 9 and 10, 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 member 300.

As shown in fig. 8, when the cylinder 210 of the adjusting slider 200 is driven by the driving member to approach the water jet 114, and the top of the swirl chamber 220 is tightly attached to the 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 flow ejected from the water jet 114 is dispersed under the action of centrifugal force, thereby generating a large cone angle water jet type with the largest cleaning area and the softest water jet.

As shown in fig. 9, 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. 10, when the adjusting slider 200 is driven by the driving member 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 in the swirl chamber 220 does not rotate at an accelerated speed, and the water flow is directly ejected from the water outlet 114, 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.

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 eccentric protrusion 320 of the driving member 300 is inserted into the guide groove 212 of the adjustment slider 200. 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 spray head 10 further includes an elastic member 400 disposed in the housing 100, the elastic member 400 is located on a side of the adjustment slider 200 away from the water outlet 114, and the elastic member 400 is abutted between the adjustment slider 200 and the second housing 120. The elastic member 400 can press the adjustment slider 200 close to the water outlet 114, and when the driving member 300 drives the adjustment slider 200 away from the water outlet 114, the elastic member 400 is compressed. More specifically, a limiting column 121 is further protruded from one side of the second housing 120 close to the adjusting slider 200, and the elastic element 400 is sleeved and fixed on the limiting column 121.

In addition, as shown in fig. 11, in some embodiments, the present application further relates to a spray gun 20, wherein the spray gun 20 is adapted to be mounted on a smart toilet lid 30, and comprises a gun barrel 21 and a spray head 10 according to any of the above embodiments, and the spray head 10 is disposed in the gun barrel 21.
