Description

Technical Field

[0001] This utility model relates to the field of sanitary products, and in particular to a water outlet device. Background Technology

[0002] Handheld showerheads are common bathing tools, typically consisting of a water spray nozzle and a handle for the user to grip. In some existing technologies, the handle length is usually fixed, and the range and distance that can be sprayed when the user holds the showerhead are also fixed. If a larger rinsing range and distance are needed, it is often necessary to turn around or bend over, which is extremely inconvenient and results in a poor user experience. Summary of the Invention

[0003] This utility model proposes a water outlet device, which aims to solve the technical problem that the spray range and distance of handheld shower heads are fixed in the prior art, making them inconvenient to use.

[0004] To achieve the above objectives, a first aspect of this utility model provides a water outlet device, comprising:

[0051] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0052] In some specific embodiments of this utility model, a water outlet device 1000 is provided, which can be a handheld shower head, a handheld spray gun or other equipment. The water outlet device 1000 is configured such that its handheld structure can be extended and retracted to achieve length adjustment, so as to meet different rinsing needs of users.

[0053] Taking the 1000 water outlet device as an example, for reference Figure 1-12 The water outlet device 1000 of this utility model embodiment includes a water outlet head 100, a roller 540, an outer rod assembly, a pressing adjustment assembly 500, and an inner rod 400 for spraying water to a user. The water outlet head 100 can be a shower head. The outer rod assembly and the inner rod 400 can slide relative to each other and be relatively fixed in a specific position, thereby realizing the extension and retraction of the handheld part of the shower head.

[0054] The outer rod assembly includes a sliding cavity and a first through hole, wherein the first through hole is disposed on the side wall of the outer rod assembly and penetrates the side wall to connect the sliding cavity with the outside.

[0055] The pressing adjustment component 500 is inserted into the outer rod assembly. The pressing adjustment component 500 includes a second through hole 522, a pressing part 511, and a stop part 524. Specifically, a portion of the pressing adjustment component 500 is inserted into the sliding cavity, and this portion is approximately annular, forming the second through hole 522. The pressing part 511 and the stop part 524 are disposed on the annular structure and positioned opposite each other on either side of the second through hole 522. The pressing part 511 is exposed to the outside through the first through hole; it can be flush with or protrude from the first through hole, as long as it allows the user to press it. The stop portion 524 is located on the side opposite to the first through hole. The stop portion 524 is provided with a receiving space 523. The roller 540 is rotatably disposed in the receiving space 523. The end of the roller 540 near the axis of the sliding cavity protrudes out of the receiving space 523. When the stop portion 524 gradually moves in the direction close to the axis of the sliding cavity, the roller 540 always abuts against the outer peripheral wall of the inner rod 400 or the slot 420 earlier than the stop portion 524.

[0056] The inner rod 400 is a hollow tubular structure with an internal flow channel 410. At least two recessed slots 420 are provided on the outer peripheral wall near the stop portion 524, spaced apart along the flow channel 410. The inner rod 400 can pass through the sliding cavity and also through the second through hole 522 of the pressing adjustment assembly 500 to connect with the water outlet 100, allowing water to flow through the flow channel 410 and into the water outlet 100 for output to the user. The inner rod 400 can also slide relative to the outer rod assembly within the sliding cavity.

[0057] The working principle and process of the water outlet device 1000 provided in this embodiment of the present invention are described below:

[0058] The number of slots 420 is defined as at least two, including at least a first slot 421 and a second slot 422, wherein when the stop part 524 engages with the first slot 421 or the second slot 422, no relative sliding occurs between the inner rod 400 and the outer rod assembly.

[0059] Specifically, when the stop part 524 engages with the first slot 421, the outer rod assembly and the inner rod 400 cannot slide against each other. At this time, the roller 540 is also located in the first slot 421. When the user applies force to the pressing part 511, it can drive the pressing adjustment component 500 to move, causing the stop part 524 and the roller 540 to disengage from the first slot 421. The outer rod assembly and the inner rod 400 can slide relative to each other. During their relative sliding, when the stop part 524 and the roller 540 move to a misalignment with the first slot 421, the user can pull the pressing adjustment component back to make the roller 540 abut against the outer peripheral wall of the inner rod 400. Alternatively, by setting a reset component, when the user withdraws the pressing force, the pressing adjustment component 500 resets to make the roller 540 abut against the outer peripheral wall of the inner rod 400. When the outer rod assembly and the inner rod 400 slide relative to each other, only the roller 540 serves as the rolling contact point between them. After the roller 540 and the stop part 524 move to coincide with the position of the second slot 422 (e.g. Figure 3 The user's pulling force or the reset force of the reset component can cause the stop part 524 to engage with the second slot 422 for positioning, at which time the water outlet device 1000 extends.

[0060] According to this embodiment of the invention, the outer rod assembly and the inner rod 400 can slide or be positioned relative to each other through the cooperation of the stop part 524 and the slot 420, allowing the handheld part of the water outlet device 1000 to extend and retract, thereby changing the length of the water outlet device 1000 and meeting the user's needs to change the spray range and distance. Furthermore, during the relative sliding process of the outer rod assembly and the inner rod 400, only the roller 540 abuts and rolls between them. The friction between the roller 540 and the inner rod 400 is rolling friction, which is less than the sliding friction generated by the direct contact between the outer rod assembly and the inner rod 400. This results in less sticking during adjustment, a smoother feel, and a better user experience.

[0061] It is understandable that there can be two slots 420 or multiple slots along the flow channel 410. Therefore, when the stop part 524 is engaged in the slots 420 at different positions, the water outlet device 1000 can be extended to different lengths to meet the various different needs of users.

[0062] refer to Figure 1-5 In some specific embodiments of this utility model, the water outlet device 1000 further includes an elastic element 530. One end of the elastic element 530 abuts against the side of the pressing part 511 near the outer rod assembly, and the other end abuts against the side of the outer rod assembly near the pressing part 511. When the user does not apply force to the pressing part 511, the elastic element 530 is also in a compressed state, continuously providing a spring force away from the outer rod assembly to the pressing adjustment assembly 500.

[0063] Understandably, since the inner rod 400 passes through the second through hole 522 and is installed in the sliding cavity, even if the elastic member 530 pushes against the pressing adjustment assembly 500, the pressing adjustment assembly 500 will not disengage from the outer rod assembly because the inner rod 400 is stuck in the second through hole 522.

[0064] In this embodiment, the elastic element 530 is actually a reset element in the water dispensing device 1000. When the user no longer applies force to the pressing part 511, the elastic element 530 will always push the pressing adjustment component 500 away from the outer rod assembly. Therefore, when the outer rod assembly and the inner rod 400 slide relative to each other, the roller 540 can always abut against the outer wall of the inner rod 400 to roll. When the stop part 524 moves to coincide with the slot 420, under the pushing of the elastic element 530, the stop part 524 automatically engages in the slot 420, eliminating the need for the user to continuously apply pressure and tension to control the sliding process. Furthermore, the elastic element 530 also provides elastic feedback and pressing feel for the user's pressing process.

[0065] refer to Figure 12 In some specific embodiments of this utility model, the inner rod 400 is provided with a planar track 430 along the rolling path of the roller 540. That is, the outer wall surface of the inner rod 400 on the side where the roller 540 abuts is set as a plane, the extending direction of the planar track 430 is the same as the axial direction of the inner rod 400, and all the slots 420 are spaced apart on the planar track 430.

[0066] It is understandable that if the outer peripheral wall of the inner rod 400 is a curved surface, then during the process of the roller 540 abutting against and rolling against the outer peripheral wall, the two are prone to relative sliding or even misalignment, which can lead to jamming.

[0067] According to the embodiment of this utility model, even if the roller 540 moves slightly laterally, its contact point with the outer peripheral wall of the inner rod 400 is still on the planar track 430. At this time, there will be no misalignment between the two, which is conducive to a more stable and smooth relative sliding process between the outer rod assembly and the inner rod 400.

[0068] refer to Figure 2 , Figure 5-7 In some specific embodiments of this utility model, the pressing assembly includes a button 510 and a movable ring 520 connected to each other. The button 510 includes a pressing part 511 and a first latch 512. The movable ring 520 includes a ring body that forms a second through hole 522. A locking head 525 is provided on one side of the ring body near the button 510, and a stop part 524 is provided on the other side. The locking head 525 can be engaged with the first latch 512, thereby achieving a latching connection between the button 510 and the movable ring 520.

[0069] Specifically, the pressing part 511 has several elastically deformable fasteners 5121 on the side near the movable ring 520. One end of each fastener 5121 is connected to the pressing part 511, and the other end extends into a locking block 5122 in a direction perpendicular to the fastener 5121. The fasteners 5121 are arranged in a ring at intervals, and the locking blocks 5122 all face the center of the ring formed by the fasteners 5121, thus forming the first buckle 512. The movable ring 520 has an abutting surface 521 on the side near the button 510, and the abutting surface 521 extends into a locking head 525 in the direction near the button 510.

[0070] When the button 510 and the movable ring 520 are assembled, the locking head 525 can be pushed forcefully against the center surrounded by multiple locking blocks 5122. The locking head 525 squeezes the locking blocks 5122, thereby deforming and opening the buckle plate 5121. After the locking head 525 enters the space enclosed by the buckle plate 5121, the buckle plate 5121 returns to its original position. The locking blocks 5122 restrict the locking head 525 from disengaging, thereby achieving fastening. The assembly is convenient and quick.

[0071] In some specific embodiments of this utility model, the elastic element 530 can be a spring, wherein when the spring abuts against the pressing part 511, the spring is sleeved outside the first buckle 512.

[0072] refer to Figure 2 , Figure 9-11 In some specific embodiments of this utility model, the outer rod assembly includes an outer rod 200 and a sleeve 300. The outer rod 200 is handheld by the user and has a first sliding cavity 210 and a button hole 220 penetrating the side wall of the outer rod 200. When the pressing adjustment component 500 is inserted into the outer rod assembly, the button 510 can be exposed through the button hole 220 for easy pressing by the user. The sleeve 300 includes a second sliding cavity 310 and a third through hole 320 penetrating the side wall of the sleeve 300.

[0073] The sleeve 300 is fixedly disposed in the first sliding cavity 210. The first sliding cavity 210 and the second sliding cavity 310 are coaxially disposed to form a sliding cavity. The third through hole 320 is disposed correspondingly to the button hole 220 to form the first through hole.

[0074] Furthermore, the maximum length of the third through hole 320 along the circumference of the sleeve 300 is greater than the maximum width of the movable ring 520. Thus, the movable ring 520 can be inserted through the third through hole 320. Also, the diameter of the button hole 220 is smaller than the maximum width of the abutting surface 521. Therefore, when the movable ring 520 is inserted into the third through hole 320 and the sleeve 300 is assembled into the outer rod 200, only the button 510 can be exposed through the button hole 220, while the abutting surface 521 can hold the smaller-diameter button hole 220 to prevent it from coming out.

[0075] refer to Figure 9-11In some specific embodiments of this utility model, a second buckle 230 is provided on the inner wall of the outer rod 200, and a third buckle 330 is provided on the outer wall of the sleeve 300. When the sleeve 300 is placed in the first sliding cavity 210, the second buckle 230 and the third buckle 330 are engaged along the axial direction of the first sliding cavity 210, thereby fixing the sleeve 300 and the outer rod 200 in the axial direction and preventing them from separating.

[0076] Furthermore, an annular recess 240 is provided on the end of the outer rod 200 near the water outlet 100, and an annular flange 340 is provided on the end of the sleeve 300 near the water outlet 100. When the second buckle 230 and the third buckle 330 are engaged, the annular flange 340 overlaps on the annular recess 240, further realizing the axial limit between the two.

[0077] refer to Figure 9-11 In some specific embodiments of this utility model, a positioning rib 250 is provided on the inner peripheral wall of the outer rod 200. Specifically, the positioning rib 250 extends along the axial direction of the first sliding cavity 210, and a strip groove 350 extending along the axial direction of the first sliding cavity 210 is provided on the sleeve 300. The end of the strip groove 350 facing away from the water outlet 100 is an opening that connects to the outside. When the sleeve 300 is inserted into the first sliding cavity 210, the positioning rib 250 is engaged in the strip groove 350, thereby preventing the sleeve 300 from rotating relative to the outer rod 200, thus achieving circumferential positioning.

[0078] It is understood that in some other specific embodiments of this utility model, the outer rod 200 may be provided with a second buckle 230 and a positioning rib 250 at the same time, and the sleeve 300 may also be provided with a third buckle 330 and a strip groove 350 at the same time, thereby limiting the axial and circumferential directions of the sleeve 300 simultaneously.

[0079] refer to Figure 9-10 In some specific embodiments of this utility model, a limiting groove 360 ​​is provided on the outer wall surface of the sleeve 300 near the key hole 220, and one end of the elastic member 530 abutting against the outer rod assembly is located in the limiting groove 360.

[0080] Specifically, the limiting groove 360 ​​can be a circular groove that is entirely concave, or it can be an annular groove that is partially concave only to fit the end of the elastic element 530.

[0081] According to the embodiment of this utility model, by setting the limiting groove 360, one end of the elastic member 530 can be limited to avoid relative sliding and displacement between the elastic member 530 and the outer wall surface of the outer rod assembly, thereby affecting the normal pressing and reset of the button 510.

[0082] refer to Figure 6-8In some specific embodiments of this utility model, the roller 540 is provided with a rotating shaft 541 on both sides, and the side wall of the accommodating space 523 is provided with a mounting hole 5243. When the roller 540 is placed in the accommodating space 523, the rotating shaft 541 is rotatably placed in the mounting hole 5243.

[0083] refer to Figure 6-8 In some specific embodiments of this utility model, the stop portion 524 includes a first stop platform 5241 and a second stop platform 5242. Specifically, the end of the movable ring 520 away from the button 510 is broken into a notch shape, which is the accommodating space 523. The portions of the ring on both sides of the accommodating space 523 are the first stop platform 5241 and the second stop platform 5242. The first stop platform 5241 and the second stop platform 5242 are each provided with a guide groove 5244 communicating with the mounting hole 5243 on their opposite side walls. The guide groove 5244 extends axially along the sliding cavity.

[0084] Therefore, when installing the roller 540, the rotating shafts 541 on both sides of the roller 540 can be pushed in through the guide groove 5244 and gradually moved into the mounting hole 5243.

[0085] Furthermore, the width of the guide groove 5244 can be set to be slightly smaller than the diameter of the rotating shaft 541, and the diameter of the mounting hole 5243 can be larger than the diameter of the rotating shaft 541. Therefore, when installing the roller 540, it is necessary to push the roller 540 with a little force to squeeze the rotating shaft 541 into the guide groove 5244 until it moves to the mounting hole 5243 and can rotate relative to the mounting hole 5243, so that the roller 540 is not easy to slip off the guide groove 5244.

[0086] Furthermore, the center of the mounting hole 5243 can be set to be not on the axis of the guide groove 5244, thereby creating a misalignment that makes it difficult for the roller 540 to slip off the guide groove 5244.

[0087] It is understandable that the guide groove 5244 can be configured to extend from the mounting hole 5243 toward the water outlet 100, or it can be configured to extend from the mounting hole 5243 toward the water outlet 100, or two guide grooves 5244 extending in opposite directions can be configured at the same time, so that the user has more choices in the installation direction.

[0088] It is understandable that the guide groove 5244 can also be set in a direction perpendicular to the axis of the sliding cavity.

[0089] refer to Figure 10In some specific embodiments of this utility model, a fourth through hole 370 is also provided on the side of the sleeve 300 away from the third through hole 320. When the pressing adjustment component 500 is inserted into the outer rod component, the stop part 524 is embedded in the fourth through hole 370, wherein, in the axial direction of the sliding cavity, the projections of the top surface 371 and the bottom surface 372 of the fourth through hole 370 coincide with the projection of the guide groove 5244.

[0090] Therefore, the top surface 371 and bottom surface 372 of the fourth through hole 370 can block the outlet of the guide groove 5244, further preventing the roller 540 from slipping off the guide groove 5244.

[0091] refer to Figure 12 In some specific embodiments of this utility model, a convex ring 440 is provided on the outer peripheral wall of the end of the inner rod 400 facing away from the water outlet head 100. The convex ring 440 extends outward along the radial direction of the inner rod 400. Therefore, when the inner rod 400 slides relative to the outer rod 200, and the water outlet device 1000 reaches its maximum length, the convex ring 440 can abut against the end of the sleeve 300 near the convex ring 440, preventing the inner rod 400 and the outer rod 200 from slipping apart.
