Description

Technical Field

[0001] The present invention relates to the technical field of bathroom products, and in particular to a water outlet switching valve that is easy to operate. Background Art

[0002] The switching structure of existing water outlet devices (such as shower heads) is mostly based on buttons and push buttons. However, whether it is a button or push button switch, the control part needs to be exposed to the product body, which affects the integrity of the product. At the same time, the exposed control part is easy to hide dirt and grime in the assembly groove and assembly gap, which is not only not conducive to cleaning, but also easy to cause the switching structure to get stuck. In addition, when the hands are wet and slippery, the operating button or push button is easy to slip, affecting the user experience. For this reason, there is also a way to set the switching structure to switch by swinging left and right, but this switching method has the problem of eccentric center of gravity on the left and right, which is not very friendly to the grip of the product and the use process, and it is easy to make switching errors during the process of swinging vigorously. In addition, due to the complex structure and the large number of structural parts, this type of solution is costly and not conducive to production. In summary, the existing switching structure is not convenient for users to use, and the complex structure is not conducive to production. Summary of the Invention

[0003] The invention discloses a water outlet switching valve which is easy to operate, and aims to improve the problems that the existing switching structure is inconvenient for users to use and has a complex structure which is not conducive to production.

The water supply valve is located adjacent to the water outlet and the water supply is closed by the water supply valve.

[0006] As a further improvement, a first limiting portion is provided on the rolling element, and a second limiting portion is provided in the rolling cavity. The first limiting portion and the second limiting portion are engaged with each other in a concave-convex manner so that the rolling element rolls along the extension direction of the second limiting portion.

[0007] As a further improvement, the rolling element is barbell-shaped, the second limiting portion is a guide rail formed by a protrusion along the inner wall of the rolling cavity, and the rolling element is adapted to the guide rail to roll along the guide rail.

[0008] As a further improvement, the linkage member is provided with an abutment portion, a pressing portion and an axis portion, the abutment portion abuts against the switching valve core, the pressing portion has an inclined surface inclined in the rolling chamber, and the axis portion is provided on both sides of the linkage member and is hinged to the main body.

[0009] As a further improvement, the switching valve core also includes a valve stem, a central shaft and an elastic member. The valve stem, water diversion plate and elastic member are all sleeved on the central shaft. The elastic member is arranged between the water diversion plate and the inner wall of the water diversion chamber. The valve stem is provided with a first bevel tooth portion, and the water diversion plate is provided with a second bevel tooth portion. The valve stem is pressed so that the first bevel tooth portion abuts against the second bevel tooth portion, thereby driving the water diversion plate to rotate accordingly.

[0010] As a further improvement, the water distribution plate is provided with three water distribution ports, and the body is provided with two water outlet channels to form three water outlet modes.

[0011] As a further improvement, the main body is provided with a water dividing part, a water passing part and a panel from the inside to the outside, the water dividing part and the water passing part form the water dividing cavity, the water dividing part is provided with a first water outlet and a second water outlet, the water passing part is provided with a first water outlet channel connected to the first water outlet and a second water outlet channel connected to the second water outlet, the panel is provided with a first area water outlet nozzle connected to the first water outlet channel and a second area water outlet nozzle connected to the second water outlet channel.

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0016] 1. This application incorporates a rolling element within the body, which abuts a linkage under the action of gravity, thereby controlling the switching valve core to switch the water outlet flow path. This simple structure and minimal components reduce costs and enhance market competitiveness. Furthermore, no external control elements are required, resulting in a clean, integrated product. This allows for single-handed operation without slipping or switching issues, facilitating user experience.

[0017] 2. The rolling element is barbell-shaped and is restricted to rolling in the direction of the guide rail, ensuring a smooth rolling path and reducing rolling resistance. This also ensures that the center of gravity of the rolling element remains on the axis of the handle during rolling, thereby ensuring a good grip when holding the device.

[0018] The rolling element is arranged in a rolling cavity where no water flows, which can avoid the influence of water flow on the rolling element.

[0044] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention for which protection is sought, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example

[0045] Combine Figures 1 to 17 , this embodiment provides a water outlet switching valve that is easy to operate, including a main body 1 and a rolling member 2, a linkage member 3 and a switching valve core 4 arranged in the main body 1; wherein the main body 1 has a water inlet channel 11, a water diversion chamber 12, a rolling chamber 13 and at least two water outlet channels; the rolling member 2 is arranged in the rolling chamber 13, one end of the linkage member 3 is extended in the rolling chamber 13, and the other end abuts the switching valve core 4; the water diversion chamber 12 is connected to the water inlet channel 11, and the switching valve core 4 is installed in the water diversion chamber 12, including a water diversion plate 41 provided with a water diversion port. When the main body 1 is facing downward, the rolling member 2 rolls in a direction close to the linkage member 3 under the action of gravity, so as to abut the linkage member 3 to press the switching valve core 4, and correspondingly drives the water diversion plate 41 to rotate, so that the water diversion port is selectively connected to the water outlet channel; when the main body 1 is facing upward, the rolling member 2 rolls back in a direction away from the linkage member 3 under the action of gravity. In this embodiment, the main body 1 facing upward is defined as the upright state with the head 17 on top and the handle 18 on the bottom, and the main body 1 facing downward is defined as the inverted state with the head 17 on the bottom and the handle 18 on the top. When in use, the user holds the handle 18 and turns the head 17 of the main body 1 downward, so that the rolling element 2 abuts against the linkage 3 and presses the switching valve core 4 to realize the water outlet switching. At this time, the water flows from the water inlet channel 11 into the water diversion chamber 12, and then enters the water outlet channel connected to the water diversion port from the water diversion port. When the main body 1 is facing upward, the rolling element 2 is reset to prepare for the next switch. In other words, when switching, just turn the main body 1 upside down and then turn it upright. It is convenient and fast, and the switching force is small. Children and the elderly can easily achieve the water splash switch.

[0046] It should be noted that in this embodiment, by disposing a rolling element 2 within the body 1 so that it abuts the linkage element 3 under the action of gravity, thereby controlling the switching valve core 4 to switch the water outlet flow path, the structure is simple and the number of parts is small, which can reduce costs and improve market competitiveness. Furthermore, there is no need for control components exposed to the body 1, resulting in a simple product appearance and a good overall appearance. It can be operated with one hand without the problem of slipping and switching failure, which is convenient for users and improves the user experience.

[0047] In a preferred embodiment, a first limiting portion 21 is provided on the rolling element 2, and a second limiting portion 14 is provided in the rolling cavity 13. The first limiting portion 21 and the second limiting portion 14 are engaged with each other to allow the rolling element 2 to roll along the extension direction of the second limiting portion 14, thereby ensuring the rolling direction of the rolling element 2 so that it can accurately abut against the linkage member 3 under the action of gravity, ensuring smooth switching. For example, the rolling element 2 is barbell-shaped, and the second limiting portion 14 is a guide rail formed by a protrusion along the inner wall of the rolling cavity 13. The two ends of the rolling element 2 are adapted to the guide rail to roll along the guide rail. The rolling element 2 is barbell-shaped and is limited to rolling in the direction of the guide rail to ensure the rolling path, reduce rolling resistance, and enable a smooth rolling process. At the same time, it is ensured that the center of gravity of the rolling element 2 remains on the axis of the handle 18 during the rolling process, thereby ensuring the hand feel when holding it.

[0048] In another embodiment, the linkage member 3 includes an abutment portion 31, a pressing portion 32, and a shaft portion 33. The abutment portion 31 abuts against the switching valve core 4. The pressing portion 32 has an inclined surface 321 that is tilted and disposed within the rolling cavity 13. The shaft portion 33 is provided on both sides of the linkage member 3 and is hingedly connected to the body 1. Specifically, the body 1 is provided with a slot 15, and the shaft portion 33 is inserted into the slot 15, so that the linkage member 3 acts as a lever. The inclined surface 321 on the pressing portion 32 further ensures that the rolling element 2 can abut against the linkage member 3 during rolling, thereby ensuring the switching effect.

[0049] Furthermore, the switching valve core 4 also includes a valve stem 42, a central shaft 43, and an elastic member 44. The valve stem 42, the water diversion plate 41, and the elastic member 44 are all sleeved on the central shaft 43. The elastic member 44 is disposed between the water diversion plate 41 and the inner wall of the water diversion chamber 12. The valve stem 42 is provided with a first beveled tooth portion 421, and the water diversion plate 41 is provided with a second beveled tooth portion 411. Pressing the valve stem 42 causes the first beveled tooth portion 421 to abut against the second beveled tooth portion 411, thereby driving the water diversion plate 41 to rotate. The elastic member 44 is preferably a spring. When the linkage 3 presses the valve stem 42, the valve stem 42 presses down the water diversion plate 41 to rotate the water diversion plate 41. At this time, the spring is in a compressed state. When the linkage 3 releases the valve stem 42, the water diversion plate 41 presses against the valve stem 42 under the elastic force of the spring, moving upward and resetting. That is, in this embodiment, each time the valve stem 42 is pressed, the water diversion plate 41 rotates a certain angle so that the water diversion port is connected to different water outlet channels, but this is not limited thereto and is not specifically limited thereto.

[0050] On the basis of the above embodiment, in an optional embodiment of the present invention, three water outlets are provided on the water distribution plate 41, and two water outlet channels are provided in the main body 1 to form three water outlet modes. For example, the main body 1 is provided with a water distribution part 5, a water flow part 6 and a panel 7 from the inside to the outside, wherein a water distribution chamber 12 is formed between the water distribution part 5 and the water flow part 6, the water distribution part 5 is provided with a first water outlet 51 and a second water outlet 52, the water flow part 6 is provided with a first water outlet channel 61 connected to the first water outlet 51 and a second water outlet channel 62 connected to the second water outlet 52, and the panel 7 is provided with a first area water outlet 71 connected to the first water outlet channel 61 and a second area water outlet 72 connected to the second water outlet channel 62. Preferably, the first area water outlet 71 is an inner circle water outlet, and the second area water outlet 72 is an outer circle water outlet.

[0051] The three water outlets of the water distribution tray 41 are the first water distribution outlet 412, the second water distribution outlet 413, and the third water distribution outlet 414. The water distribution tray 41 is also provided with a water sealing portion 415. The water sealing portion 415 and the three water distribution outlets are arranged on the water distribution tray 41 in four equal parts, that is, the angle between two adjacent water distribution outlets is 90°. In the initial state, the first water outlet 51 and the second water distribution outlet 413 are aligned and connected, and the second water outlet 52 is aligned and sealed with the water sealing portion 415. At this time, water flows from the water inlet channel 11 into the water distribution chamber 12, then from the first water outlet 51 into the first water outlet channel 61, and then flows out of the first area water outlet 71, forming the first water outlet mode.

[0052] Action 1, reference Figure 3 , turn the body 1 downward, and the rolling member 2 moves downward under the action of gravity, so that the rolling member 2 abuts against the inclined surface 321 of the linkage member 3, thereby prying the linkage member 3 to press the valve stem 42 to move toward the panel 7, and the water distribution plate 41 rotates 45° under the combined force of the spring and the valve stem 42; Action 2, refer to Figure 2, the main body 1 faces upward, and under the action of gravity, the rolling element 2 leaves the linkage element 3, and under the combined force of the spring and the valve stem 42, the water diversion plate 41 rotates 45° again. At this time, the first water diversion port 412 is connected to the first water outlet 51, and the third water diversion port 414 is connected to the second water outlet 52, corresponding to the first water outlet channel 61 and the second water outlet channel 62 both discharging water, that is, the first area water outlet nozzle 71 and the second area water outlet nozzle 72 discharge water at the same time, forming a second water outlet mode. Repeating action one and action two again, the first water outlet 51 is aligned with the water sealing part 415, and the second water outlet 52 is aligned with the second water diversion port 413. At this time, the first water outlet channel 61 does not discharge water, and the second water outlet channel 62 discharges water, forming a third water outlet mode in which only the second area water outlet nozzle 72 discharges water. By repeating action one and action two in this way, the first water outlet mode, the second water outlet mode and the third water outlet mode can be cyclically switched in order.

[0053] In other embodiments, the rolling cavity 13 is formed between the outer wall of the water diversion member 5 and the inner wall of the main body 1, and no water flows through it. A guide rib 16 is protruded from the main body 1 to limit the rolling direction of the rolling member 2. The rolling member 2 is arranged in the rolling cavity 13 where no water flows through, which can avoid the influence of water flow on the rolling of the rolling member 2. At the same time, the material of the rolling member 2 is not restricted by the water flow requirement, and a wider range of materials can be selected. The provision of the guide rib 16 can further ensure the rolling direction of the rolling member 2. Preferably, the material of the rolling member 2 is stainless steel. On the one hand, it can ensure the weight of the rolling member 2 so that the rolling member 2 can pry up the linkage member 3 under the action of its own gravity. On the other hand, it can ensure the life and strength of the rolling member 2 and avoid the problem of rust on the rolling member 2 in a humid environment.
