Description

Technical Field

[0001] This utility model relates to the technical field of water outlet devices, and in particular to a water outlet regulator and a faucet. Background Technology

[0002] A water flow regulator is a device used to control the output state of water (such as flow rate, pressure, temperature, etc.), and is widely used in domestic water supply, industrial pipelines, agricultural irrigation, sanitary ware and other scenarios.

[0003] An aerator is a water flow regulator used in faucets or other water outlets. Aerators are typically installed at the water outlet of faucets or other water outlets. The aerator converts the water flow from a pipe into a linear flow, then uses air pressure to convert the linear flow into a jet, and finally distributes the water evenly, making the water smoother. The water flowing from the faucet or water outlet mixes thoroughly with air, creating a foaming effect and thus improving the impact of the water flow.

[0004] The existing Chinese patent with authorization announcement number CN203215063U discloses a detachable faucet aerator structure, including a valve body, a handle connected to the control end of the valve body, and a water outlet pipe connected to the water outlet of the valve body. The water outlet pipe has an aerator in the inner cavity at the end, and a screw hole is opened on the inner wall of the water outlet pipe. The aerator is fixedly connected to the inner cavity of the water outlet pipe by a screw passing through the screw hole.

[0005] The existing technical solution described above has the following drawbacks: the detachable faucet aerator structure fixes the aerator to the water outlet by making screw holes in the pipe wall. Since the screw holes are made on the back of the water outlet pipe that does not face the user, it is not convenient for a drilling machine with up-and-down feed to process the screw holes on the back of the water outlet pipe. Making screw holes will also reduce the strength of the water outlet pipe and may also easily lead to water leakage. The detachable faucet aerator structure has the drawback of poor practicality. Utility Model Content

[0007] The above-mentioned utility model objective is achieved through the following technical solution: a water outlet regulator, comprising a shell having a cavity, a guide block groove formed on the outer side wall of the shell, a sliding locking block slidably disposed in the guide block groove, and a retaining block disposed on the sliding locking block and retaining and limiting the retaining platform in the water outlet.

[0008] The present invention is further configured such that: an insertion hole communicating with the guide block groove is provided on the top surface of the outer shell, an insertion block with a limiting groove on the bottom surface is inserted into the insertion hole, and the top of the sliding lock block is embedded in the limiting groove and slides in cooperation with the limiting groove.

[0009] The present invention is further configured such that: the guide block groove is connected to the shell cavity, and the end of the sliding lock block near the shell cavity is provided with a limiting plate that slides and fits against the shell cavity wall.

[0010] The present invention is further configured such that: a limited sliding groove is provided on the sliding lock block, and a limited sliding buckle is provided on the bottom wall of the guide block groove to engage with the limited sliding groove.

[0011] The present invention is further configured such that: an external air inlet is provided on the outer side wall of the outer shell, which communicates with the shell cavity; a protruding ring with its side wall connected to the insert block is inserted into the shell cavity; and an anti-disengagement buckle is provided on the outer side wall of the protruding ring, which engages with the external air inlet.

[0012] The present invention is further configured such that: a rectifier is provided on the outer shell above the shell cavity; a converging groove and a rectifier hole are sequentially connected on the top surface of the rectifier; a convex ring is provided on the bottom surface of the rectifier and has a mixing cavity in the middle that communicates with the rectifier hole; and an inner air inlet hole communicating with the mixing cavity is provided on the outer side wall of the convex ring.

[0013] The present invention is further configured such that: a mounting groove communicating with the top of the rectifier is provided on the top surface of the rectifier; a filter screen with filter holes is embedded in the mounting groove; and a plurality of locking buckles that abut against the top surface of the filter screen are provided on the groove wall of the mounting groove.

[0014] The present invention is further configured such that: a foaming element with an upper foaming net in the middle is provided inside the shell cavity.

[0015] A faucet equipped with the above-mentioned water outlet regulator includes a faucet body with a water outlet regulator inside the water outlet.

[0028] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model clearer and easier to understand, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] As Figure 1 shown, the present utility model provides a water outlet regulator, which includes a filter screen 25, a rectifying member 17, a foaming member 15, and a housing 1 through which water flows in sequence.

[0030] As Figure 2 and 3 shown, the middle part of the housing 1 has a housing cavity 2, and the housing cavity 2 penetrates through the upper and lower end faces of the housing 1. A guide block chute 3 is opened on the side wall of the housing 1. The cross-section of the guide block chute 3 is "Г"-shaped, and the guide block chute 3 is communicated with the housing cavity 2. A sliding lock block 4 is slidably arranged in the guide block chute 3, and the cross-section of the sliding lock block 4 is "Г"-shaped. A pressing block 5 is fixedly connected to the end face of the sliding lock block 4 facing away from the guide block chute 3, and the pressing block 5 can be pressed and limited against a pressing table 33 in the water outlet 31 of the faucet body 30.

[0031] As Figure 2 and 3 shown, a jack 6 is opened on the top surface of the housing 1, and the jack 6 is simultaneously communicated with the guide block chute 3 and the housing cavity 2. A convex ring 7 is inserted into the top of the housing cavity 2. An insertion block 9 is fixedly connected to the outer side wall of the convex ring 7. The insertion block 9 is in the shape of "冖" with a downward opening, and the insertion block 9 is in plug-in fit with the jack 6. A limiting groove 10 is opened on the bottom surface of the insertion block 9. The cross-section of the limiting groove 10 is rectangular, and the top of the sliding lock block 4 is embedded in the limiting groove 10 and is in sliding fit with the limiting groove 10.

[0032] The present water outlet regulator is provided with a limiting groove 10 on the insertion block 9 that is in sliding fit with the top of the sliding lock block 4. The limiting groove 10 plays a guiding role for the sliding lock block 4 to make reciprocating transverse movements along the guide block chute 3. At the same time, the insertion block 9 presses and limits the sliding lock block 4 in the guide block chute 3, restricting the separation of the sliding lock block 4 from the guide block chute 3.

[0033] As Figure 2 and 3 shown, a limiting plate 11 is fixedly connected to the end of the sliding lock block 4 close to the housing cavity 2. The limiting plate 11 is in sliding contact with the cavity wall of the housing cavity 2, and the limiting plate 11 is used to restrict the separation of the sliding lock block 4 from the guide block chute 3.

[0034] As Figure 3 shown, a sliding limit buckle 12 is fixedly connected to the middle of the bottom wall of the guide block chute 3. The cross-section of the sliding limit buckle 12 is racetrack-shaped. A sliding limit slot 13 is penetrated and opened on the end face of the sliding lock block 4 facing away from the guide block chute 3, and the sliding limit slot 13 is in snap-fit with the sliding limit buckle 12, thereby restricting the lateral sliding of the sliding lock block 4 in the guide block chute 3.

[0035] like Figure 1 and 3 As shown, in this embodiment, the water outlet regulator can be used with the existing card ejector 14, and can also be used with small needle-like devices such as toothpicks and wires.

[0036] In this embodiment, when the water outlet regulator is working: the worker or user inserts a small needle-like component such as the card pick 14 into the sliding lock block 4's limiting slot 13, and then moves the sliding lock block 4 by using the small needle-like component such as the card pick 14. When the limiting buckle 12 is engaged in the limiting slot 13, the sliding lock block 4 is restricted to slide laterally in the guide block groove 3.

[0037] like Figure 2 As shown, the bottom of the cavity 2 has a lower foaming mesh integrally connected to the outer shell 1, and the lower foaming mesh has a fine mesh structure. A foaming element 15 is embedded in the middle of the cavity 2, and the foaming element 15 is located directly above the lower foaming mesh. The middle of the foaming element 15 has an upper foaming mesh 16, and the upper foaming mesh 16 has a fine mesh structure.

[0038] like Figure 2 and 4 As shown, the rectifier 17 is disposed above the housing cavity 2. A convex ring 7 with a mixing chamber 8 in the middle is integrally connected to the bottom surface of the rectifier 17. The cross-section of the mixing chamber 8 is racetrack-shaped. Two internal air inlets 18 are symmetrically opened on the outer side wall of the convex ring 7. The internal air inlets 18 are rectangular holes. An external air inlet 19 communicating with the housing cavity 2 is opened through the outer side wall of the housing 1. The external air inlet 19 is a rectangular hole and can be aligned with the internal air inlets 18.

[0039] like Figure 2 and 3 As shown, a sealing groove 20 is provided circumferentially on the outer side wall of the rectifier 17, and a sealing ring 21 is embedded in the sealing groove 20. The sealing ring 21 is used to form a seal between the water outlet regulator and the inner wall of the faucet body 30.

[0040] like Figure 2 and 4 As shown, the top surface of the rectifier 17 has a mounting groove 22, a confluence groove 23, and a rectifier hole 24 connected in sequence. The cross-sections of the mounting groove 22 and the confluence groove 23 are both racetrack-shaped. The flow area of ​​the confluence groove 23 is smaller than that of the mounting groove 22. The rectifier hole 24 is a circular hole and is evenly distributed. All the rectifier holes 24 are connected to the mixing chamber 8.

[0041] like Figure 1 and 2As shown, a filter screen 25 with filter holes is embedded in the mounting groove 22. The filter holes are evenly distributed on the filter screen 25. The filter screen 25 is used to filter impurities in the water, which to a certain extent limits the possibility of impurities in the water entering the water outlet regulator and causing blockage. A pair of locking buckles 26 are fixedly connected to the two opposite walls of the mounting groove 22. Multiple locking buckles 26 abut against the top surface of the filter screen 25, pressing and fixing the filter screen 25 in the mounting groove 22, preventing the filter screen 25 from separating from the mounting groove 22.

[0042] like Figure 2 As shown, two anti-detachment buckles 27 are fixedly connected to the outer wall of the convex ring 7. The two anti-detachment buckles 27 are respectively engaged with the two external air inlets 19. The length of the anti-detachment buckle 27 is less than the length of the external air inlet 19. When the anti-detachment buckle 27 is engaged with the external air inlet 19, the external air inlet 19 has a gap for air to pass through, and the rectifier 17 is restricted from separating from the outer shell 1.

[0043] like Figure 3 As shown, two snap-fit ​​holes 28 are symmetrically opened on the outer side wall of the outer casing 1. The snap-fit ​​holes 28 are connected to both the guide block groove 3 and the casing cavity 2. Two mutually symmetrical snap-fit ​​buckles 29 are fixedly connected to the outer side wall of the convex ring 7. The two snap-fit ​​buckles 29 are engaged with the two snap-fit ​​holes 28 respectively, thus restricting the separation of the rectifier 17 from the outer casing 1.

[0044] The detailed working process of the water outlet regulator in this embodiment is as follows:

[0045] S1: After being filtered by the filter screen 25, the water will flow into the confluence tank 23.

[0046] S2: The water flow in the confluence channel 23 enters the mixing chamber 8 through the uniformly distributed rectification holes 24. The uniformly distributed rectification holes 24 can make the water flow evenly into the mixing chamber 8, improve the uniformity of water flow distribution, and achieve the rectification effect.

[0047] S3: When the water in the confluence channel 23 enters the mixing chamber 8 through the rectifier hole 24, which is a small hole, the flow area is reduced and the resistance is increased, achieving the effect of flow restriction. It will also cause a local pressure drop in the mixing chamber 8 (forming a negative pressure zone). Then, the air is drawn into the mixing chamber 8 through the outer air inlet 19 and the inner air inlet 18 in sequence. The drawn-in air and the high-speed fluid collide and mix violently in the mixing chamber 8. The kinetic energy of the fluid cuts the air into tiny bubbles, forming a gas-liquid two-phase fluid.

[0048] S4: The gas-liquid two-phase fluid in the mixing chamber 8 will pass through the upper bubbler 16 and the lower bubbler in sequence. The upper bubbler 16 and the lower bubbler can cut the fluid multiple times, increase the gas-liquid contact area, and make the bubbles evenly dispersed in the water flow to form a milky white foamy water flow.

[0049] This water outlet regulator can successively filter, rectify, limit the flow, and foam the passing water flow, so that the ejected water flow can form a milky white foam shape, the water flow is softer and more stable, and it is not easy to waste water due to reduction, which is conducive to saving water.

[0050] As Figure 5 and 6 shown, the present utility model also proposes a faucet equipped with the above water outlet regulator, including a faucet body 30 having a water outlet 31. The water outlet 31 is a port for water to flow out in the inner cavity of the faucet body 30, and the water outlet regulator is installed in the water outlet 31. When the faucet equipped with the above water outlet regulator works, the water flow forms a milky white foam-like water flow after passing through the water outlet regulator and is ejected outwards.

[0051] An installation chute 32 that slidably cooperates with the abutting block 5 is provided on the inner wall of the water outlet 31. The cross-section of the installation chute 32 is in the shape of "冖", and the installation chute 32 includes a pair of access chutes 321 and a transverse movement chute 322. The transverse movement chute 322 is connected to the upper ends of the two access chutes 321, and both the transverse movement chute 322 and the two access chutes 321 slidably cooperate with the abutting block 5.

[0052] A abutting platform 33 is provided on the bottom wall of the installation chute 32. The abutting platform 33 is integrally connected to the faucet body 30. The abutting platform 33 is located between the two access chutes 321. The abutting platform 33 restricts the water outlet regulator from being pulled out of the water outlet 31 of the faucet body 30 by abutting and limiting the abutting block 5.

[0053] The detailed process of installing the water outlet regulator in the faucet in this embodiment is as follows:

[0054] S1: In the initial state, the worker or user toggles the sliding lock block 4 and the abutting block 5 to both ends of the guide block chute 3, and then the worker or user inserts the water outlet regulator into the water outlet 31 of the faucet body 30 until the abutting block 5 slides into the transverse movement chute 322 through the access chute 321;

[0055] S2: The worker or user inserts a fine needle-like component such as a card-taking needle 14 into the anti-slip card slot 13 of the sliding lock block 4, and then toggles the sliding lock block 4 through a fine needle-like component such as the card-taking needle 14. When the anti-slip buckle 12 is stuck in the anti-slip card slot 13, the sliding lock block 4 is restricted from sliding transversely in the guide block chute 3. At this time, the abutting block 5 abuts against the top surface of the abutting platform 33, and the water outlet regulator is restricted from being pulled out of the water outlet 31 of the faucet body 30.

[0056] This faucet installs the water outlet regulator in a way that avoids drilling screw holes, solving the technical problems in the prior art such as inconvenient screw hole processing, reduction of the strength of the faucet body 30 due to opening screw holes, and water leakage of the faucet body 30 due to opening screw holes, and has good practicability.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
