Description

Technical Field

[0001] The invention relates to the field of water outlet devices, in particular to a water outlet nozzle and a water outlet device. Background Art

[0002] Some water outlet devices are provided with water outlets. In order to avoid dripping caused by residual water in the water outlet device after the switch is turned off, some existing technologies provide water stop parts such as pistons and springs in the water outlets. When water is discharged, the water flow pushes the piston to overcome the elastic force of the spring to open the water channel and discharge water. When the switch is turned off, the water pressure disappears and the piston gradually closes the water channel, causing the water flow and flow rate to gradually decrease, resulting in a small amount of water output and difficulty in actual use within the time range from turning off the switch to completely stopping the water, resulting in this part of the water being wasted. Summary of the invention

[0003] The present invention provides a water outlet and a water outlet device, aiming to solve the technical problem that the water outlet with a water stop in the prior art has a small water outlet and is difficult to use in practice within the time range from closing the switch to completely stopping the water.

[0004] To achieve the above object, a first aspect of the present invention provides a water spout, comprising: A main body, wherein the main body is provided with a water inlet and a first water passage cavity, and water can flow from the water inlet to the first water passage cavity, and the main body further comprises a second water passage cavity and a water outlet cavity, wherein a first water passage cavity is provided between the first water passage cavity and the second water passage cavity, and the second water passage cavity and the water outlet cavity are connected through the second water passage cavity; a water stop member, arranged in the first water passage cavity, comprising a blocking member and an elastic member, one end of the elastic member abutting against a wall of the second water passage cavity away from the water inlet, and the other end abutting against the blocking member, when no water flows through the water outlet, the elastic force of the elastic member causes the blocking member to block the first water outlet, and when water flows toward the water outlet, the blocking member overcomes the elastic force of the elastic member under the action of the water flow and moves to open the first water outlet, so that the first water passage cavity and the second water passage cavity are connected; Wherein, a water flow cross-sectional area of ​​the first water flow outlet is greater than a water flow cross-sectional area of ​​the second water flow outlet.

[0005] According to the water outlet provided by the embodiment of the first aspect of the present invention, the flow rate through the first water outlet is greater than the flow rate of the second water outlet. Therefore, the water flow entering the second water chamber through the first water outlet cannot be completely drained from the second water outlet immediately. A part of the remaining water flow is temporarily stored in the second water chamber. When the water inlet flow is closed, the blocking member gradually blocks the first water outlet under the push of the elastic member, and the water flow entering the second water chamber through the first water outlet gradually decreases until the flow rate is 0. At this time, since a certain amount of water flow is stored in the second water chamber, a certain flow rate can still be maintained to flow evenly from the second water chamber to the water outlet chamber, which can still meet the actual use needs of users and will not be wasted. In addition, the water in the second water chamber can also slow down the flow of water flowing in from the first water outlet, so that the water flow is more uniform when flowing out of the second water outlet, and the water outlet effect is better.

[0006] According to some embodiments of the present invention, a pressure relief hole is provided on the wall surface of the first water passage chamber that abuts against the elastic member.

[0007] According to some embodiments of the present invention, a limiting cavity is provided on a side of the blocking member close to the elastic member, and the elastic member penetrates into the limiting cavity to abut against the blocking member.

[0009] According to some embodiments of the present invention, a guide section is provided on one end of the first water passage chamber away from the elastic member, and the guide section is provided between the water inlet and the first water passage. The water flow cross-sectional area of ​​the guide section gradually expands along the water inlet direction. When the piston blocks the first water passage, the piston penetrates into the guide section.

[0010] According to some embodiments of the present invention, a bubbler is provided in the water outlet cavity.

[0011] According to some embodiments of the present invention, a baffle is provided in the water outlet cavity, and a projection of the second water outlet along the water inlet direction at least partially overlaps with the baffle.

Water outlet device. DETAILED DESCRIPTION

[0017] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0018] refer to Figure 1 and Figure 2 In some specific embodiments of the present invention, a water outlet 1000 is provided, including a main body and a water stopper 400, wherein a water inlet 110 and a first water passage chamber 120 are arranged on the main body, and water can flow from the water inlet 110 to the first water passage chamber 120, and the main body also includes a second water passage chamber 210 and a water outlet chamber 240, and a first water passage 130 is arranged between the first water passage chamber 120 and the second water passage chamber 210, and the second water passage chamber 210 and the water outlet chamber 240 are connected by setting a second water passage 220, thereby, water can flow in from the water inlet 110, and flow through the first water passage chamber 120 and the second water passage chamber 210 in sequence, and then flow out from the water outlet chamber 240.

[0019] The water stopper 400 is disposed in the first water passage chamber 120 and is used to open or close the first water passage port 130. The water stopper 400 includes a blocking member 410 and an elastic member 420. The blocking member 410 may be a piston, a plug, etc., and the elastic member 420 may be a spring, etc. Specifically, one end of the elastic member 420 abuts against the inner wall surface of the first water passage chamber 120 away from the water inlet 110, and the other end abuts against the blocking member 410. When no water flows through the water outlet 1000, the elastic member 420 provides an elastic force toward the water inlet 110 to the blocking member 410, so that the blocking member 410 blocks the first water passage port 130.

[0020] Therefore, when water flows toward the water outlet 1000, the water pressure can push the blocking member 410 to overcome the elastic force of the elastic member 420, and the blocking member 410 gradually moves in the direction of compressing the elastic member 420. At this time, the first water outlet 130 is opened, and the water entering from the water inlet 110 can flow from the first water passage chamber 120 into the second water passage chamber 210. When no water flows through the water outlet switch water outlet 1000, the blocking member 410 is moved in the direction close to the water inlet 110 by the elastic force of the elastic member 420 to block the first water outlet 130, thereby achieving water stopping and avoiding the phenomenon of residual water dripping after the water flow is closed.

[0021] Furthermore, the water flow cross-sectional area of ​​the first water outlet 130 is greater than the water flow cross-sectional area of ​​the second water outlet 220. Therefore, the flow rate through the first water outlet 130 is greater than the flow rate of the second water outlet 220. Therefore, the water flow entering the second water passage chamber 210 through the first water outlet 130 cannot be completely discharged from the second water outlet 220 immediately, but a part of the remaining water flow will be temporarily stored in the second water passage chamber 210. At this time, the second water passage chamber 210 not only flows water, but also plays a role in storing water. When the water inlet flow is closed, the blocking member 410 gradually blocks the first water outlet 130 under the push of the elastic member 420, and the water flow entering the second water passage chamber 210 through the first water outlet 130 gradually decreases until the flow rate is 0. At this time, since a certain amount of water flow is stored in the second water passage chamber 210, a certain flow rate can still be maintained to flow evenly from the second water outlet 220 to the water outlet chamber 240, which can still meet the actual use needs of users and will not be wasted. Furthermore, the water stored in the second water passage chamber 210 can also slow down the water flowing in from the first water passage 130, so that the water flows out from the second water passage 220 more evenly and the water outlet effect is better.

[0022] It is particularly pointed out here that the first water outlet 130 and / or the second water outlet 220 can be provided in plurality, as long as the total water flow cross-sectional area of ​​the plurality of first water outlets 130 is greater than the total water flow cross-sectional area of ​​the plurality of second water outlets 220 .

[0023] refer to Figure 1 , Figure 4 and Figure 5In some specific embodiments of the present invention, a pressure relief hole 230 is provided on the wall surface where the first water passage chamber 120 abuts against the elastic member 420. In order to avoid water seepage and water cross-talk between different parts, sealing members such as rubber rings are usually provided at the connection and abutment between the parts. For example, a sealing ring is provided on the peripheral wall of the blocking member 410, and the outer peripheral surface of the blocking member 410 is sealed with the inner wall surface of the first water passage chamber 120 by the sealing ring. At this time, the space where the elastic member 420 is located is sealed. When water flows through and pushes the blocking member 410 to move, the space where the elastic member 420 is located will be compressed and pressured, affecting the normal movement of the blocking member 410, thereby affecting the passage of water. In this embodiment, by providing the pressure relief hole 230, during the movement of the blocking member 410, pressure balance can be achieved in real time to avoid pressure holding.

[0024] Specifically, the pressure relief hole 230 may penetrate the wall of the first water passage chamber 420 and connect the first water passage chamber 420 with the water outlet chamber 240 to achieve pressure balance.

[0025] It is understandable that the pressure relief hole 230 may also be disposed at other locations as long as the first water passage chamber 240 can be connected to the outside to achieve pressure balance.

[0026] refer to Figure 1 In some specific embodiments of the present invention, a limited cavity 411 is provided on the side of the blocking member 410 close to the elastic member 420. Specifically, a certain space may be hollowed out on the side of the blocking member 410 close to the elastic member 420 to form a cavity, and one end of the elastic member 420 close to the blocking member 410 may be inserted into the cavity and abut against the inner wall of the cavity. In this way, the elastic member 420 may be limited to extend and retract only along the movement direction of the blocking member 410, avoiding tilting and affecting the movement of the blocking member 410.

[0027] refer to Figure 3 In some specific embodiments of the present invention, the water inlet 110 includes a first water inlet section 111, a tapered section 112, and a second water inlet section 113 connected in sequence along the water inlet direction, wherein a water flow cross-sectional area of ​​the second water inlet section 113 is smaller than a water flow cross-sectional area of ​​the first water inlet section 111.

[0028] According to an embodiment of the present invention, when the water flows through the first water inlet section 111, the tapered section 112 and the second water inlet section 113 in sequence, the water flow will be pressurized due to the gradual reduction of the water flow cross-sectional area, thereby enhancing the pushing effect of the water flow on the blocking member 410. Therefore, even if the water inlet pressure is relatively small, the blocking member 410 can be pushed by the pressurization, thereby preventing the water outlet 1000 from being unable to open and discharge water.

[0029] refer to Figure 3In some specific embodiments of the present invention, a guide section 121 is provided on one end of the first water passage chamber 120 away from the elastic member 420. Specifically, a portion of the first water passage chamber 120 located between the water inlet 110 and the first water passage port 130 is the guide section 121. The water flow cross-sectional area of ​​the guide section 121 gradually expands along the water inlet direction. When the blocking member 410 blocks the first water passage port 130, one end of the blocking member 410 penetrates into the guide section 121.

[0030] According to an embodiment of the present invention, by providing a guide section 121 that gradually expands along the water inlet direction, the blocking member 410 can be guided to penetrate into the guide section 121 more easily, and the gradually shrinking part of the guide section 121 can guide the end face of the blocking member 410 to seal the water inlet 110, forming a double seal between the blocking first water outlet 130, thereby enhancing the sealing and intercepting effect.

[0031] refer to Figure 1 and Figure 2 In some specific embodiments of the present invention, a bubbler 500 is further provided in the water outlet chamber 240. When water flows through, it can be mixed with the gas sucked in by the bubbler 500 to output bubble water, thereby meeting the user's demand for bubble water.

[0032] refer to Figure 1 and Figure 5 In some specific embodiments of the present invention, a baffle plate 241 is provided in the water outlet cavity 240, and the projection of the second water outlet 220 along the water inlet direction at least partially overlaps with the baffle plate 241. Specifically, the baffle plate 241 may be an annular plate installed in the water outlet cavity 240, or an annular rib extending integrally from the inner side wall of the water outlet cavity 240, and the baffle plate 241 may be arranged perpendicular to the direction of the water flow entering from the second water outlet 220, or may have a certain angle with the water inlet direction.

[0033] By setting the baffle plate 241, the water flow entering the water outlet chamber 240 from the second water outlet 220 can first hit the baffle plate 241 to change its flow direction, so that the water flow is gathered in the water outlet chamber 240, and it is prevented that the water flow flows into the second water outlet 220 and then flows directly out of the water outlet chamber 240 along the inflow direction, thereby achieving the effect of slowing down the flow and making the water outlet more uniform.

[0034] refer to Figure 1 and Figure 2In some specific embodiments of the present invention, the main body includes a water inlet 100, a water outlet 200 and a shell 300, wherein the water inlet 110 and the first water outlet 130 are both arranged on the water inlet 100, the second water outlet 220, the water outlet cavity 240, the baffle 241 and the pressure relief hole 230 are all arranged on the water outlet 200, the water inlet 100 and the water outlet 200 are connected to enclose the first water outlet cavity 120, and the shell 300 wraps the connected water inlet 100 and the water outlet 200, and together encloses the second water outlet cavity 210.

[0035] refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 In some specific embodiments of the present invention, a first slot 250 is provided on one of the water inlet member 100 and the water outlet member 200, and a block 150 is provided on the other. The water inlet member 100 and the water outlet member 200 are limited in the circumferential direction by the block 150 being clamped in the first slot 250 to avoid mutual rotation. It can be understood that at this time, the water inlet member 100 and the water outlet member 200 can be limited in the axial direction by directly wrapping them with the outer shell 300.

[0036] In some specific embodiments of the present invention, a retaining spring 600 is further included, a second retaining groove 140 is provided on the water inlet member 100, and a third retaining groove 260 is provided on the water outlet member 200. When the water inlet member 100 and the water outlet member 200 are connected, the second retaining groove 140 and the third retaining groove 260 are opposite to each other, and the retaining spring 600 is inserted to be simultaneously engaged in the second retaining groove 140 and the third retaining groove 260, thereby completing the axial connection between the water inlet member 100 and the water outlet member 200.

[0037] It is understandable that the circumferential limitation can be achieved in the axial direction through the first clamping groove 250 and the clamping block 150 , and the axial connection can be completed through the cooperation of the clamping spring 600 , the second clamping groove 140 and the third clamping groove 260 .

[0038] refer to Figure 6 In another specific embodiment of the present invention, a water outlet device 2000 is also provided, which may be a faucet, etc., and the water outlet nozzle 1000 is arranged in the water outlet device 2000.

[0039] Specifically, the water outlet nozzle 1000 may be installed in the water outlet end of the water outlet device 2000 as a separate water outlet component, or the portion of the shell of the water outlet device 2000 close to the water outlet end may be the outer shell 300 of the water outlet nozzle 1000 .
