Description

Technical Field

[0001] The invention relates to a button switching structure and a water outlet device. Background Art

[0002] At present, the button switching structure often has problems such as unsmooth switching and switching failure when the button is pressed to the bottom, resulting in unstable product functions. In addition, the number of functional parts required for the button water channel switching structure is large, and the total error after the matching dimensions are superimposed is large. In production, the dimensional accuracy of each part is required to be high, and it is easy to have the problem of switching function failure or instability due to the large dimensional deviation of one of the parts. The most important thing is that when these button switching structures are applied to the water outlet device, these buttons are used for single use. After being pressed, they cannot be pressed again to switch. Each button corresponds to a water channel. When a button is pressed, the water channel is opened. If the water channel needs to be closed, it can only be reset by another button, that is, the water channel needs to be closed. When the combined water is discharged, if two buttons are pressed, when one of the buttons needs to be retained, the two buttons can only be closed by the third button first, and the button to be retained can be pressed again to open the separate water outlet of the water channel. This requires two actions to complete, which cannot bring a minimalist experience. Summary of the invention

[0029] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0030] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0032] Referring to the drawings of the specification, a button switching structure includes: at least two moving shafts 10, all of which can move axially along themselves, and a driving end 11 is provided on the moving shaft; a passive component 20, and a first action part 21 and a clamping part 22 are provided on the passive component, and the first action part can be moved after being acted on by the driving end, so that the moving shaft and the clamping part cooperate; a first reset member 31, the first reset member is connected with the moving shaft, and the first reset member can restore the moving shaft to its initial position without being affected by external force; a second reset member 32, the second reset member is connected with the passive component, and the second reset member can restore the passive component to its initial position after moving, and the initial position can refer to the drawings of the specification. Figure 4 , the passive component in the figure is also in the initial position. In one embodiment of the present invention, four moving shafts are used as an example for explanation. Referring to the accompanying drawings, the initial position of the moving shaft is to cooperate with the corresponding water outlet so that the water outlet cannot discharge water. Under the action of the first reset member, the moving shaft maintains a downward movement trend. At this time, the driving end can be in contact with the first action site or not. When the moving shaft is moved upward (the number is not limited), the driving end acts on the first action site to make the passive component move laterally relative to the moving shaft (it can also be said to be perpendicular to the axial direction of the moving shaft) until the driving end moves to the clamping part. At this time, under the action of the second reset member, the passive component is reset to the initial position, and the driving end is clamped. The connecting part is fixed so that the movable shaft will not move downward under the action of the first reset member. At this time, the movable shaft is in the first position, and the water outlet is opened to discharge water. Then one of the movable shafts is moved again, no matter it is in the first position or the initial position, this movable shaft will cooperate with the first action part or the second action part to move the passive component, and release the clamping relationship between the movable shaft and the passive component just in the first position, so that the movable shaft just in the first position returns to the initial position. The movable shaft that moves again will have the driving end of the movable shaft cooperate with the clamping part under the action of the first reset member when the force disappears, and the water outlet of the movable shaft is in an open state to pass water. The implementation method will be described in detail again below.

[0033] Preferably, when the movable shaft cooperates with the clamping portion, the movable shaft is in a first position. The first position can be referred to in the accompanying drawings of the specification. Figure 6 , which means that the moving shaft in the figure moves upward, and the passive component also includes a second action part 23, which can be moved after being acted upon by the driving end, and can restore the moving shaft that is in the first position and has not moved to its initial position, that is, when other moving shafts act on the first action part or the second action part, the moving shaft in the first position will be reset to its initial position, and at this time its corresponding water outlet is closed and no water flows.

[0034] Furthermore, the passive component is provided with a first action part, a clamping part, and a second action part in sequence along the axial direction of the moving shaft. The moving shaft is first connected with the first action part in an initial position. Referring to the attached figure of the specification, the moving shaft in the figure moves upward from the initial position, that is to say, the passive component is provided with a first action part, a clamping part, and a second action part in sequence from bottom to top.

[0035] Furthermore, the driving end is a protruding snap-in piece on the side of the moving shaft, the snap-in portion is a snap-in groove provided on the passive component, the snap-in piece can be snap-into the snap-in groove to place the moving shaft in the first position, the first action part and the second action part are guide slopes provided on the passive component, the two guide slopes are distributed above and below the snap-in groove in the figure, and also include a third reset member 33 connected with the passive component, the third reset member can make the passive component move radially relative to the moving shaft seat. The three reset members described in the present invention can be parts that can provide elastic force, such as springs, tension springs, and elastic sheets.

[0036] Reference Manual Attachments Figure 1 In one embodiment of the present invention, the passive component is a straight rod, the clamping portion and the first action portion are arranged on one end surface of the straight rod, and the other end surface is connected to the second reset member, and the movable axis is arranged side by side along the length direction of the straight rod.

[0037] In another embodiment of the present invention, the passive component includes a rotor 24, and a connecting rod 25 is arranged in an annular manner on the outer circumference of the rotor. The clamping portion and the first action portion are arranged on one end surface of the connecting rod, and are connected to the second reset member on the other end surface of the connecting rod. The movable shaft can cooperate with the corresponding connecting rod to drive the passive component to rotate.

[0038] In the above two embodiments of the present invention, the force direction of the moving shaft is upward, the first reset member applies a downward force to the moving shaft, and the final moving direction of the passive component is perpendicular to the moving direction of the moving shaft, that is, lateral movement, which can be lateral linear movement or lateral rotational movement, and finally the moving shaft can be fixed in the first position under the action of the second reset member. Figure 1 , Figure 2 , the four moving axes are numbered A1, A2, A3, and A4 from left to right. When A1 moves to the first position, pressing any one of A2-A4 can return A1 to the initial position. When A1-A3 move to the first position at the same time, pressing A4 can return A1-A3 to the initial position at the same time. However, when pressing any one of A1-A3, such as A1, at this time, A2 and A3 may return to the initial position, and A1 can continue to stay in the first position after letting go. In this way, when multiple water outlets are discharged at the same time, the others can be removed and only one water outlet can be retained. It is not necessary to close all water outlets and then open one of them. It is simple and convenient. Moreover, the present invention can realize the discharge of water from all waterways, that is, all moving axes reach the first position at the same time, that is, all buttons are pressed. The buttons of the prior art cannot be pressed again in this state, but the present invention can. The present invention can rotate and press any of the four buttons again. At this time, the button that has not been pressed is reset, so that the corresponding moving axis returns to the initial position, and the water is turned off, and a certain water outlet waterway is retained.

[0039] In a preferred embodiment of the present invention, a mating inclined surface 26 and a mating end surface 27 are sequentially arranged between the clamping portion and the first action portion. When the driving end of the movable shaft located at the initial position acts on the first action portion and moves upward, the passive component moves laterally. When the driving end cooperates with the mating end surface, the upward movement of the movable shaft is stopped, and the lateral movement of the passive component ends. The movable shaft also cooperates with the clamping portion. The driving end of the movable shaft located at the first position contacts and cooperates with the mating inclined surface and then slides out of the clamping portion. Under the action of the first resetting member, the movable shaft just located at the first position returns to the initial position, thereby releasing the movable shaft that has just moved. In this way, all movable shafts return to their initial positions, thereby achieving the blocking of all water outlets and realizing the overall water shut-off.

[0040] The present invention also discloses another technical feature:

[0041] A water outlet device comprises the above-mentioned button switching structure.

[0042] Specifically, it also includes a body 40, in which a water passage cavity 41 is arranged, in which the passive component is arranged, and a water outlet 42 which can be connected to the water passage cavity is arranged on the body, and the water outlet corresponds to the movable shaft one by one; when the movable shaft is in the initial position, the movable shaft can block the water outlet, and when the movable shaft cooperates with the clamping part, the movable shaft opens the water outlet to discharge water, and each movable shaft cooperates with a water outlet. A sealing ring 43 which can cooperate with the water outlet is arranged at one end of the movable shaft, and the other end of the movable shaft extends out of the body and is connected with the button 44; a first reset member is arranged between one end of the movable shaft and the body, and the first reset member drives the movable shaft to move toward the water outlet, a second reset member is arranged between the passive component and the body, and the second reset member drives the passive component to move toward the movable shaft, and a third reset member is arranged between the passive component and the body, and the first reset member plays a stabilizing role, and the force direction of the third reset member is consistent with that of the first reset member. The main body also includes a water channel 45, which corresponds to the water outlet one by one. The number of the water channels, water outlets and movable axes is the same. When the sealing ring does not seal the water outlet, the water outlet is opened, and water flows through the water channel. Finally, water can be discharged from the panel of the water outlet device.

[0043] More specifically, the present invention provides two action parts to prevent users from mistakenly pressing all buttons at the same time, which may cause product failure.
