Description

Technical Field

[0001] This utility model relates to the field of bathroom product technology, and more specifically, to a press-assisted reset structure. Background Technology

[0002] Existing push-button switching structures, such as the push-button switching shower head disclosed in Chinese patent CN105478252A, include a water distribution plate and a ratchet mounted on the water circuit device to rotate synchronously, and a drive structure to drive the ratchet to rotate. The drive structure includes a transmission frame, a transmission component, and a drive mechanism. The transmission frame is slidably connected to the water circuit device and can move away from or near the ratchet; the transmission component is slidably mounted on the transmission frame and can abut against the ratchet teeth to rotate the ratchet; the drive mechanism includes a button connected to the water circuit device and a drive component installed between the button and the transmission mechanism. In this type of solution, in order for the button to be linked to the transmission component, a transmission reversing structure is required to change the transmission direction of the button. Therefore, the transmission structure between the button and the transmission component is complex. For example, the above solution uses a steel wire unit and a drive rod structure. The reset of the transmission component relies solely on the spring force, which can easily lead to jamming or poor reset, resulting in poor button pressing feel or even failure of the push-button switching function. Utility Model Content

[0003] This utility model discloses a press-assisted reset structure, which aims to improve the problems of easy jamming and unsmooth reset in the existing press-switching structure.

[0004] The present invention adopts the following solution: A press-assisted reset structure, installed on a water outlet device, is used to control a water distribution plate within the device. It is characterized by comprising a drive component, a transmission component, a stop component, and a button. The drive component is linked to the water distribution plate, and the transmission component has an assist groove extending along its direction of movement. The stop component abuts against the assist groove to generate an assisting force for the transmission component's reset. During operation, pressing the button exposed on the water outlet device pushes the transmission component to move, thereby causing the drive component to rotate the water distribution plate. When the button is released, the transmission component moves under the action of an elastic element and resets with the assistance of the stop component.

[0005] As a further improvement, the side of the transmission member away from the button is provided with an elastic element. When the button is pressed, the transmission member compresses the elastic element and moves. When the button is released, the transmission member resets under the elastic force of the elastic element.

[0006] As a further improvement, the transmission component is provided with a stop hole, and when the transmission component moves, the stop component is movably engaged with the stop hole to position the transmission component.

[0007] As a further improvement, the stop member is arranged perpendicular to the transmission member, and the cross-sectional shape of the assist groove along the moving direction is arc-shaped.

[0008] As a further improvement, the button is located on the side of the water outlet device, and the movement direction of the transmission member is configured to be the same as the pressing direction of the button.

[0009] As a further improvement, the driving component is a ratchet, which is coaxially configured with the water distribution plate and can rotate synchronously with the water distribution plate. The transmission component is equipped with a swingable pawl, and the water outlet device is equipped with an anti-rotation pawl for abutting and limiting the ratchet teeth. When the button is pressed, the pawl drives the ratchet to rotate in a first direction, and the anti-rotation pawl is used to prevent the ratchet from rotating in a second direction opposite to the first direction, so that the ratchet stays in the current position.

[0010] As a further improvement, when the transmission component is reset, it synchronously drives the pawl to swing in a direction that yields to the ratchet teeth, so that the pawl is reset.

[0011] As a further improvement, the pawl includes a hook portion, a swing portion, and a turntable portion. The hook portion is used to abut against the ratchet tooth, the swing portion is disposed in the limiting groove of the transmission member, and the turntable portion has a positioning portion for limiting the swing angle of the pawl.

[0012] As a further improvement, the transmission component is provided with a first locking part and a first guide part, and the water outlet device is provided with a second locking part and a second guide part. The first guide part engages with the second guide part to limit the transmission component along the axial direction. The first guide part and the second guide part engage with each other to restrict the movement direction of the transmission component.

[0013] As a further improvement, the button is provided with a connecting rod, and the connecting part of the transmission component is sleeved on the connecting rod and limited along the axial direction of the connecting rod.

[0014] By adopting the above technical solution, the present invention can achieve the following technical effects: 1. This application provides an assist groove on the transmission component so that when the transmission component moves and resets, the stop component abuts against the assist groove to form an auxiliary force for resetting the transmission component, thereby ensuring smooth resetting of the transmission component and avoiding the problem of resetting jamming.

[0015] 2. The button is located on the side of the water outlet device, and the direction of movement of the transmission component is the same as the direction of button pressing. In other words, there is no need to set up a component between the button and the transmission component to change the transmission direction, thereby simplifying the transmission structure between the button and the transmission component, reducing the resistance during the reset process of the transmission component, ensuring a smooth reset process, preventing problems such as reset jamming, and thus ensuring the button's pressing feel and avoiding switching function failure.

[0016] 3. The elastic element and the button are respectively located on both sides of the transmission component, so that the transmission component and the button can reset synchronously, further reducing the reset resistance. At the same time, the structure is simple and compact, occupies little space, and helps to reduce the product size. Attached Figure Description

The terms “first,” “second,” etc., are only used to distinguish different objects and should not be construed as indicating or implying relative importance or the quantity, specific order, or primary or secondary relationship of the indicated technical features.

[0022] Combination Figures 1 to 16 This embodiment provides a press-assisted reset structure, installed on a water outlet device 8, for controlling the water distribution plate 7 within the water outlet device 8. It includes a drive member, a transmission member 2, a stop member 24, and a button 3. The drive member is linked to the water distribution plate 7. The transmission member 2 has an assist groove 25 extending along its moving direction. The stop member 24 abuts against the assist groove 25 to generate an assisting force for the reset of the transmission member 2. During operation, pressing the button 3 exposed on the water outlet device 8 pushes the transmission member 2 to move, thereby causing the drive member to rotate the water distribution plate 7. When the button 3 is released, the transmission member 2 moves under the action of the elastic member 6 and resets with the assistance of the stop member 24. Furthermore, the button 3 is located on the side of the water outlet device 8, and the moving direction of the transmission member 2 is configured to be the same as the pressing direction of the button 3.

[0023] It should be noted that, in this embodiment, by providing an assist groove 25 on the transmission component 2, when the transmission component 2 moves and resets, the stop component 24 abuts against the assist groove 25 to form an auxiliary force for resetting the transmission component, thereby ensuring smooth resetting of the transmission component 2 and avoiding the problem of resetting jamming. At the same time, the button 3 is arranged on the side of the water outlet device 8, and the moving direction of the transmission component 2 is the same as the pressing direction of the button 3. That is to say, there is no need to provide a component for changing the transmission direction between the button 3 and the transmission component 2, thereby simplifying the transmission structure between the button 3 and the transmission component 2, reducing the resistance during the resetting process of the transmission component 2, ensuring a smooth resetting process, preventing problems such as resetting jamming, and thus ensuring the pressing feel of the button 3 and avoiding the failure of the switching function.

[0024] In a preferred embodiment, the driving component is a ratchet 1, which is coaxially configured with the water distribution plate 7 and can rotate synchronously with the water distribution plate 7. The transmission component 2 is equipped with a swingable pawl 4, and the water outlet device 8 is equipped with an anti-rotation pawl 5 for abutting and limiting the ratchet 11 of the ratchet 1. When the button 3 is pressed, the pawl 4 drives the ratchet 1 to rotate in a first direction, and the anti-rotation pawl 5 is used to prevent the ratchet 1 from rotating in a second direction opposite to the first direction, so that the ratchet 1 stays in the current position. Further, when the transmission component 2 resets, it synchronously drives the pawl 4 to swing in the direction that displaces the ratchet 11, so that the pawl 4 resets. For example, the first direction is clockwise, and the second direction is counterclockwise. The ratchet teeth 11 on the ratchet 1 are inclined outward in a clockwise direction. When button 3 is pressed, the pawl 4 drives the ratchet 1 to rotate counterclockwise. During the rotation of the ratchet 1, the anti-rotation pawl 5 yields to the ratchet teeth 11. When the rotation stops, the anti-rotation pawl 5 abuts against the ratchet teeth 11, so that the ratchet 1 stays in the current position. When button 3 is released, the transmission component 2 moves in the reset direction, and the pawl 4 swings clockwise under the action of the transmission component 2 to yield to the ratchet teeth 11, thereby returning to the initial position to achieve reset and prepare for the next press. It is easy to understand that in this embodiment, each time button 3 is pressed, the ratchet 1 rotates counterclockwise once, which correspondingly drives the water distribution plate 7 to rotate once, realizing one water outlet switch.

[0025] For example, ratchet 1 is fitted onto the rotating shaft 71 of the water distribution plate 7. The rotating shaft 71 has an elongated cross-sectional shape, and the shaft hole 12 of ratchet 1 is similar in shape to the cross-sectional shape of the rotating shaft 71, so that ratchet 1 can drive the water distribution plate 7 to rotate synchronously, thereby switching the water outlet channel 823 that is connected to the water inlet channel 821, and realizing the switching of the water outlet function. The top of the rotating shaft 71 is also provided with a buckle. During installation, the rotating shaft 71 is passed through the shaft hole 12, and the buckle is engaged with the end face of the ratchet 1, so that the ratchet 1 is axially limited.

[0026] In one embodiment, the pawl 4 includes a hook portion 41, a swing portion 42, and a turntable portion 43. The hook portion 41 abuts against the ratchet 11. The swing portion 42 is disposed in the limiting groove 21 of the transmission member 2. The turntable portion 43 has a positioning portion 431 for limiting the swing angle of the pawl 4. For example, the positioning portion 431 protrudes along the outer wall of the turntable portion 43. The mounting plate 81 of the water outlet device 8 is provided with an assembly groove 811. The turntable portion 43 is installed in the assembly groove 811. A limiting portion 812 adapted to the positioning portion 431 protrudes along the side wall of the assembly groove 811. When the button 3 is pressed, the transmission member 2 moves, and the turntable portion 43 is limited by the assembly groove 811. The transmission member 2 moves the swing portion 42 to make the turntable portion rotate, which correspondingly causes the hook portion 41 to abut against the ratchet 11 to drive the ratchet 1 to rotate. When the positioning part 431 abuts against the limiting part 812, the ratchet 1 stops rotating and remains in its current position under the action of the anti-rotation pawl 5. This limits the angle of rotation of the ratchet 1 each time, ensuring accurate position switching.

[0027] In another embodiment, the side of the transmission member 2 away from the button 3 abuts against an elastic member 6. When the button 3 is pressed, the transmission member 2 compresses the elastic member 6 to move; when the button 3 is released, the transmission member 2 resets under the elastic force of the elastic member 6. One end of the elastic member 6 is disposed in the first receiving hole 22 of the transmission member 2, and the other end abuts against the second receiving hole 813 on the mounting plate 81. Preferably, the elastic member 6 is a spring, and the spring and the button 3 are respectively disposed on both sides of the transmission member 2 to facilitate synchronous reset of the transmission member 2 and the button 3, further reducing reset resistance. This design is simple in structure, occupies little space, and helps to reduce product size.

[0028] Based on the above embodiments, in an optional embodiment of this utility model, the transmission member 2 is provided with a stop hole 23. When the transmission member 2 moves, the stop member 24 is movably engaged with the stop hole 23 to position the transmission member 2. For example, the stop hole 23 is located at the bottom of the transmission member 2, and the stop member 24 includes a spring 241 and a spring. The spring 241 is always in contact with the bottom surface of the transmission member 2 under the elastic force of the spring. Pressing the button 3 moves the stop hole 23 on the transmission member 2 to the stop member 24. When the spring 241 falls into the stop hole 23, a clicking sound is emitted to indicate that the user has pressed it into place. When the transmission member 2 resets, the spring 241 slides out of the stop hole 23.

[0029] Furthermore, the stop member 24 is arranged perpendicular to the transmission member 2. The cross-sectional shape of the assist groove 25 along the moving direction is arc-shaped. When the transmission member 2 moves and resets, the stop member 24 abuts against the arc-shaped surface of the assist groove 25 to form an auxiliary force for resetting the transmission member 2. It should be noted that in this embodiment, when the stop member 24 abuts against the arc-shaped surface, it will form a lateral force. The direction of this force is the same as the moving direction of the transmission member 2. With the addition of the auxiliary force of the stop member 24 on the basis of the elastic force of the elastic member 6, the smooth reset of the transmission member 2 can be further ensured. Compared with the prior art, this embodiment has a simple structure, fewer transmission parts, and correspondingly less transmission resistance and loss. In addition, the auxiliary force of the stop member 24 can fully guarantee the reset of the transmission member 2, thereby extending the service life of the press-assisted reset structure.

[0030] Based on the above embodiments, in an optional embodiment of this utility model, the transmission component 2 is provided with a first locking part 26 and a first guide part 27, and the water outlet device 8 is provided with a second locking part 814 and a second guide part 815. The first guide part 27 and the second guide part 815 engage to limit the transmission component 2 along the axial direction. The first guide part 27 and the second guide part 815 engage with each other to limit the movement direction of the transmission component 2. For example, the first locking part 26 is a buckle, the second locking part 814 is a slot, the first guide part 27 is a groove, and the second guide part 815 is a guide rail. During installation, the first guide part 27 and the second guide part 815 are aligned, and then the buckle is inserted along the slot and fastened, so that the transmission component 2 is limited along the axial direction. The setting of the guide rail and the groove can ensure the movement direction and prevent the transmission component 2 from shaking.

[0031] In other embodiments, the button 3 is provided with a connecting rod 31, and the connecting portion 28 of the transmission member 2 is sleeved on the connecting rod 31 and limited along the axial direction of the connecting rod 31. For example, the connecting rod 31 is provided with a buckle. During installation, the connecting rod 31 passes through the mounting hole 281 on the connecting portion 28, and the connecting portion 28 is limited along the axial direction under the action of the buckle, so that the button 3 and the transmission member 2 can move in the same direction.

[0032] Another embodiment of this utility model provides a water outlet device, including a body 82 and a press-assisted reset structure as described in any of the above embodiments, disposed on the body 82. The body 82 has a water inlet channel 821, a water distribution chamber 822, and multiple water outlet channels 823 communicating with the water distribution chamber 822. A water distribution plate 7 is disposed within the water distribution chamber 822 and has a water outlet 72 communicating with the water inlet channel 821. The press-assisted reset structure drives the water distribution plate 7 to rotate, thereby switching the water outlet channel 823 communicating with the water outlet 72. For example, the water outlet device 8 is a shower head, and each water outlet channel 823 corresponds to a water nozzle to achieve switching between different water spray patterns. Preferably, the button 3 is located on the side wall of the handle near the shower head, allowing for one-handed operation of the water outlet switching, making it convenient for the user.
