A water outlet component

Abstract

This utility model discloses a water outlet assembly, including an outer rod, an inner rod, and a movable ring. The outer rod has a connected sliding cavity and a mounting cavity. The outer wall of the inner rod has at least two slots along the sliding direction of the inner rod. The movable ring is embedded in the mounting cavity and has a spring arm and a stop portion. The movable ring can be driven to move laterally from a first position to a second position within the mounting cavity. When the movable ring is in the first position, the stop portion engages with one of the slots, fixing the inner rod and outer rod relatively. When the movable ring is in the second position, the spring arm is deformed by the pressure of the inner wall of the mounting cavity, and the stop portion disengages from the slot, allowing the inner rod and outer rod to slide relative to each other. The spring arm can recover its deformation, driving the movable ring to move from the second position to the first position. This invention achieves the reset of the movable ring solely through the engagement of the movable ring's own spring arm with the inner wall of the mounting cavity, reducing the low assembly efficiency and assembly smoothness caused by multiple parts, and improving production capacity.

Description

Technical Field

[0001] This utility model relates to the field of bathroom product technology, and in particular to a water outlet component. Background Technology

[0002] Related technology discloses a telescopic shower head whose inlet pipe and handle can slide relative to each other. Locking and unlocking of the inlet pipe and handle are controlled by a button that moves a limiting component. Specifically, a spring is provided between the button and the handle. The reaction force after the button compresses the spring resets the button and drives the limiting component to move, thus locking and unlocking the inlet pipe and handle. However, the above technology uses a spring, which requires pre-compression during assembly to achieve complete assembly. This increases the difficulty of the assembly process or necessitates the use of additional tools, affecting assembly efficiency and increasing costs. Utility Model Content

[0003] The present invention aims to at least partially solve one of the aforementioned technical problems in the related art. To this end, the present invention proposes a water outlet assembly.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] The water outlet component according to an embodiment of the present utility model includes:

[0006] The outer rod has a connected sliding cavity and a mounting cavity inside, and one side of the mounting cavity has an opening;

[0007] An inner rod is slidably inserted into the sliding cavity. The interior of the inner rod has a water channel, and at least two slots are provided on the outer wall of the inner rod along the sliding direction of the inner rod.

[0008] A movable ring is fitted into the mounting cavity, and the movable ring has a spring arm and a stop portion;

[0009] The movable ring can be driven to move laterally from a first position to a second position within the mounting cavity. When the movable ring is in the first position, the stop part engages with one of the slots to fix the inner rod and the outer rod relative to each other. When the movable ring is in the second position, the spring arm is deformed by the pressure of the inner wall of the mounting cavity, and at the same time, the stop part exits the slot to allow the inner rod and the outer rod to slide relative to each other. The spring arm can restore its deformation and drive the movable ring to move from the second position to the first position.

[0010] The water outlet component according to the embodiment of this utility model has at least the following beneficial effects:

[0011] In the telescopic state, pressing the movable ring moves it to the second position. The spring arm changes from a clearance fit to an interference fit with the inner wall of the mounting cavity. The spring arm deforms under force, and the inner rod and outer rod can slide relative to each other. When the pressing force on the movable ring disappears, the elastic force generated by the spring arm's deformation can drive the movable ring back to the first position. This process only uses the movable ring's own spring arm to cooperate with the inner wall of the mounting cavity to achieve the reset of the movable ring. There is no need to add other elastic elements (such as springs or rubber parts) to assist the movement of the movable ring, which saves costs and reduces the low assembly efficiency and assembly smoothness caused by multiple parts, thereby improving production capacity.

[0012] According to some embodiments of the present invention, a sleeve is also included, on which the mounting cavity is formed. The sleeve is fixedly installed inside the outer rod, and a through hole is provided on the side wall of the outer rod, the through hole being opposite to the opening.

[0013] According to some embodiments of the present invention, a button is also included, the button being located within the through hole and connected to the movable ring.

[0014] According to some embodiments of the present invention, the movable ring has a driving part located in the opening. The driving part is in the shape of a convex column, and its outer peripheral wall has a first flange. The button is provided with a mounting hole post, and the inner peripheral wall of the mounting hole post has a smooth second flange. The driving part is inserted into the mounting hole post by pressing the second flange with the first flange.

[0015] According to some embodiments of the present invention, the inner wall of the outer rod is provided with a supporting protrusion along the circumference, a vertical positioning rib is provided above the supporting protrusion, a positioning groove is provided at the lower end of the outer wall of the sleeve, the bottom of the sleeve abuts against the supporting protrusion, and the positioning rib is inserted into the positioning groove.

[0016] According to some embodiments of this utility model, the opening is located on the left side of the mounting cavity, the driving part is located on the left side of the movable ring, the stop part is located on the right side of the movable ring, and the front and rear sides of the movable ring are provided with connecting rods to connect the driving part and the stop part. The movable ring has two spring arms, which are located on the front and rear sides of the movable ring respectively. The front and rear walls of the mounting cavity are both provided with inclined surfaces, which gradually slope towards the inside of the mounting cavity from left to right. The spring arms can be deformed by the compression of the inclined surfaces when moving along the inclined surfaces.

[0017] According to some embodiments of this utility model, the spring arm and the connecting rod on the same side of the movable ring are located in the same vertical direction, and the outer wall of the spring arm does not extend beyond the outer wall of the connecting rod in the vertical direction. The front wall and the rear wall of the mounting cavity both have protrusions, and the inclined surface is provided on the protrusions. The connecting rod on the front side of the movable ring is in clearance fit with the front wall of the mounting cavity, and the connecting rod on the rear side of the movable ring is in clearance fit with the rear wall of the mounting cavity.

[0018] According to some embodiments of the present invention, the spring arm and the connecting rod on the same side of the movable ring are located in the same vertical direction, and the outer side of the spring arm has a boss that extends beyond the outer wall of the connecting rod in the vertical direction.

[0019] According to some embodiments of the present invention, a roller is also included, and a receiving space is provided in the stop portion. The roller is rotatably disposed in the receiving space. When the inner rod and the outer rod slide relative to each other, the roller can roll into contact with the outer wall of the inner rod.

[0020] According to some embodiments of the present invention, a shower head is also included, wherein the shower head is sealed to the end of the inner rod so that the water outlet channel of the shower head is connected to the water channel.

[0038] Reference Figure 1-12 A water outlet assembly, comprising:

[0039] The outer rod 100 has a sliding cavity 110 and a mounting cavity 210 that are connected inside, and one side of the mounting cavity 210 has an opening 211;

[0040] The inner rod 300 is slidably inserted into the sliding cavity 110. The inner rod 300 has a water channel 310 inside. At least two slots 320 are provided on the outer wall of the inner rod 300 along the sliding direction of the inner rod 300. The sliding direction of the inner rod 300 is the up and down direction.

[0041] A movable ring 400 is fitted into a mounting cavity 210. The movable ring 400 has a spring arm 420 and a stop portion 430.

[0042] The movable ring 400 can be driven to move laterally from a first position to a second position within the mounting cavity 210. When the movable ring 400 is in the first position, the stop part 430 engages with one of the slots 320 to fix the inner rod 300 and the outer rod 100 relative to each other. When the movable ring 400 is in the second position, the spring arm 420 is deformed by the pressure of the inner wall of the mounting cavity 210, and at the same time, the stop part 430 exits the slot 320 to allow the inner rod 300 and the outer rod 100 to slide relative to each other. The spring arm 420 can restore its deformation and drive the movable ring 400 to move from the second position to the first position.

[0043] Working principle: In the fixed state, the movable ring 400 is in the first position, and the stop part 430 cooperates with the slot 320, so that the inner rod 300 and the outer rod 100 are relatively fixed. In the telescopic state, pressing the movable ring 400 causes it to move to the right, and the stop part 430 disengages from the slot 320. At this time, the inner rod 300 and the outer rod 100 can slide relative to each other. The inner rod 300 can move upward to extend the outer rod 100 until the next slot 320 connects with the stop part 430, realizing the extension of the handheld part of the water outlet component. During the pressing process, the spring arm 420 changes from a clearance fit to an interference fit with the inner wall of the mounting cavity 210, and the spring arm 420 deforms under force. When the pressing force of the movable ring 400 disappears, the elastic force generated by the spring arm 420 restoring its deformation can drive the movable ring 400 to move to the left and return to the fixed state.

[0044] In some embodiments of this utility model, a sleeve 200 is further included. The sleeve 200 has a mounting cavity 210 formed on it and is fixedly installed inside the outer rod 100. A through hole 140 is formed on the side wall of the outer rod 100, opposite to the opening 211. The sleeve 200 can be processed separately as an independent component, making its structural design and dimensional accuracy easier to guarantee, thus simplifying the manufacturing process of the outer rod 100. The fit between the sleeve 200, the outer rod 100, and the movable ring 400 can be modularly assembled through separate design, improving assembly flexibility and fault tolerance.

[0045] In some embodiments of this utility model, a button 500 is also included. The button 500 is located within the through hole 140 and is connected to the movable ring 400. During installation, the movable ring 400 is inserted into the mounting cavity 210 of the sleeve 200, then the sleeve 200 is inserted into the outer rod 100, then the inner rod 300 is inserted into the outer rod 100, and finally the button 500 is inserted into the movable ring 400 through the through hole 140 to complete the assembly. The button 500 provides users with a more convenient and comfortable point of force application. Compared to directly operating the movable ring 400, the button 500 can be designed in an ergonomic shape to reduce hand discomfort during operation. The button 500 is located within the through hole 140 of the outer rod 100, which can prevent external moisture and impurities from directly contacting the movable ring 400 and the interior of the mounting cavity 210, reducing wear or jamming of components caused by contaminants entering, and extending the service life of the movable ring 400 and other internal structures. Button 500 can also match the shape and color of outer rod 100, making the structure at through hole 140 more aesthetically pleasing and harmonious, reducing the abruptness caused by exposed internal components, and improving the overall quality of the product.

[0046] In some embodiments of this utility model, the movable ring 400 has a driving part 410 located in the opening 211. The driving part 410 is shaped like a convex pillar, and its outer peripheral wall has a first flange 411. The button 500 is provided with a mounting hole post 510, and the inner peripheral wall of the mounting hole post 510 has a smooth second flange 512. The driving part 410 is inserted into the mounting hole post 510 by pressing the second flange 512 with the first flange 411. Furthermore, the outer contours of both the first flange 411 and the second flange 512 are arc-shaped, allowing the driving part 410 to quickly engage with the mounting hole post 510 through compression. This eliminates the need for additional fasteners, simplifying the assembly process. Simultaneously, the mutual limiting of the flanges forms a stable axial constraint, preventing the button 500 from falling off the driving part 410 during use.

[0047] In some embodiments of this utility model, the inner wall of the outer rod 100 is provided with a supporting protrusion 120 along the circumferential direction, and a vertical positioning rib 130 is provided above the supporting protrusion 120. The lower end of the outer wall of the sleeve 200 is provided with a positioning groove 220, the bottom of the sleeve 200 abuts against the supporting protrusion 120, and the positioning rib 130 is inserted into the positioning groove 220. The structure of the positioning rib 130 being inserted into the positioning groove 220 can restrict the rotation of the sleeve 200 relative to the outer rod 100 in the circumferential direction, ensuring that the opening 211 on the sleeve 200 is precisely aligned with the through hole 140 of the outer rod 100, ensuring the positional correspondence between the button 500 and the drive part 410, and preventing the operating parts from being misaligned due to the rotation of the sleeve 200.

[0048] In some embodiments of this utility model, the opening 211 is located on the left side of the mounting cavity 210, the movable ring 400 is generally square, the driving part 410 is located on the left side of the movable ring 400, the stop part 430 is located on the right side of the movable ring 400, the front and rear sides of the movable ring 400 are provided with connecting rod parts 440 to connect the driving part 410 and the stop part 430, the movable ring 400 has two spring arms 420, the two spring arms 420 are located on the front and rear sides of the movable ring 400 respectively, the front wall and the rear wall of the mounting cavity 210 are both provided with inclined surfaces 230, the inclined surfaces 230 gradually slope towards the inside of the mounting cavity 210 from left to right, the spring arms 420 can be deformed by the compression of the inclined surfaces 230 when moving along the inclined surfaces 230. When the movable ring 400 moves from the first position (left) to the second position (right), the spring arm 420 gradually presses inward along the inclined plane 230, and the degree of deformation increases with the increase of displacement (elastic potential energy is gradually stored). When the pressing force disappears, the recovery deformation of the spring arm 420 will generate a leftward thrust along the inclined plane 230, driving the movable ring 400 to accurately reset.

[0049] In some embodiments of this utility model, such as Figure 4 , 5 As shown in Figures 7 and 8, the spring arm 420 and the connecting rod portion 440 on the same side of the movable ring 400 are located in the same vertical direction, and the outer wall surface of the spring arm 420 does not extend beyond the outer wall surface of the connecting rod portion 440 in the vertical direction. Both the front and rear walls of the mounting cavity 210 have protrusions 240, and inclined surfaces 230 are provided on the protrusions 240. The connecting rod portion 440 on the front side of the movable ring 400 is in clearance fit with the front wall of the mounting cavity 210, and the connecting rod portion 440 on the rear side of the movable ring 400 is in clearance fit with the rear wall of the mounting cavity 210. The spring arm 420 and connecting rod portion 440 on the same side refer to the spring arm 420 and connecting rod portion 440 on the front side of the movable ring 400, and the spring arm 420 and connecting rod portion 440 on the rear side of the movable ring 400. The protrusion 240 makes the inclined surface 230 more "protruding" relative to the inner wall of the mounting cavity 210. The inclined surface 230 does not interfere with the connecting rod 440, ensuring that the inclined surface 230 only forms an interference fit with the spring arm 420 and does not interfere with other parts on the movable ring 400 (such as the connecting rod 440), reducing ineffective friction and ensuring the smooth movement of the movable ring 400.

[0050] In some embodiments of this utility model, such as Figure 9-11As shown, the spring arm 420 and the connecting rod portion 440 on the same side of the movable ring 400 are located in the same vertical direction. The outer side of the spring arm 420 has a boss 421, which extends beyond the outer wall of the connecting rod portion 440 in the vertical direction. When the movable ring 400 moves to the point where the spring arm 420 contacts the inclined surface 230, the boss 421 will form an interference fit with the inclined surface 230 before the connecting rod portion 440. The compression between the boss 421 and the inclined surface 230 will cause the spring arm 420 to deform. However, since the connecting rod portion 440 has not reached the distance to contact the inclined surface 230, the inclined surface 230 does not interfere with the connecting rod portion 440. This ensures that the inclined surface 230 only forms an interference fit with the spring arm 420 and does not form an interference fit with other parts of the movable ring 400 (such as the connecting rod portion 440), reducing ineffective friction and ensuring the smooth movement of the movable ring 400.

[0051] In some embodiments of this utility model, a roller 600 is also included, and a receiving space 431 is provided in the stop portion 430. The roller 600 is rotatably disposed in the receiving space 431. When the inner rod 300 and the outer rod 100 slide relative to each other, the roller 600 can roll contact with the outer wall of the inner rod 300. During the relative sliding process of the outer rod 100 and the inner rod 300, only the roller 600 makes rolling contact between them. The friction between the roller 600 and the inner rod 300 is rolling friction. Compared with the sliding friction generated by the direct contact between the outer rod 100 and the inner rod 300, the friction force is smaller, reducing the user's sense of sticking during adjustment, making the feel smoother, and improving the user experience.

[0052] In some embodiments of this utility model, a shower head is also included, which is sealed to the end of the inner rod 300 so that the water outlet channel of the shower head is connected to the water channel 310. The water outlet assembly of this utility model is applied to a handheld shower head, with the outer rod 100 serving as a handle and the inner rod 300 serving as a water inlet pipe, enabling the extension and retraction of the handheld shower head to meet the user's needs for changing the spray range and distance.

[0053] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
