Description

Technical Field

[0001] This utility model relates to the field of bathroom technology, and more specifically, to a water outlet switching device and its shower head that saves effort. Background Technology

[0002] Existing water dispensing devices primarily rely on manual operation by the user, adjusting the valve body and switching mechanism to achieve different water dispensing effects. Most switching mechanisms typically employ a rotary valve core or slide bar structure to control the direction and intensity of the water flow. However, the movement of the switching mechanism often requires overcoming significant resistance from water pressure, especially in high-pressure environments. Pressing the switch results in even greater friction, forcing the user to apply more force to complete the switching operation. This not only increases the user's workload but also, under frequent use, can easily lead to accelerated wear and tear on components due to improper operation, reducing their service life.

[0003] Furthermore, commercially available switching mechanisms, designed to achieve multiple water output effects, are often more complex and intricate in their structural design. These mechanisms involve the coordinated operation of multiple moving parts, requiring higher precision and making operation more inconvenient. This can easily lead to water flow interruption or leakage during switching. In addition, the complex structure also means increased maintenance difficulty in case of malfunctions, thus affecting the overall user experience and product reliability.

[0004] In particular, during the switching process, the limited switching movement and sealing performance of the valve body often lead to water flow interruptions or instability. This not only affects the water output but may also cause uneven water flow impact, thus impacting the overall performance and user experience. This is especially prominent in situations requiring stable water flow, negatively affecting the user experience and limiting its promotion and use in a wider range of applications, directly impacting the product's practicality and market competitiveness.

[0006] The present invention adopts the following solution:

[0007] This application provides a labor-saving water outlet switching device, including a water channel assembly, a switching assembly, and a water outlet assembly; the water channel assembly has a water-passing body, which has at least an inlet, a first outlet, a movable channel, and a first water passage for connecting the inlet and the first outlet; the switching assembly includes a switching shaft, a piston portion formed at one end of the switching shaft, and a pressing portion formed at the other end of the switching shaft; the switching assembly has a corresponding second outlet, and the interior of the switching shaft has a second water passage connecting the second outlet. The water outlet assembly includes a first water outlet component connected to a first water outlet to form a water splash, and a second water outlet component connected to a second water outlet to form a different water splash; the water inlet allows water to enter laterally into the second water passage, and the piston is movably and sealed within the movable channel, which can isolate the movable channel from the first and second water passages, so that during the pressing and switching process, the piston is protected from direct water pressure within the movable channel, thereby making it easier to drive the switching shaft by pressing, and select the first or second water outlet for water dispensing.

[0008] As a further improvement, the movable channel is connected to the outside, making the piston part suitable for insertion into the movable channel so as to freely switch positions; wherein, the cross-section of the second water passage is smaller than the cross-section of the movable channel, and when pressing to switch to the first water outlet for water dispensing, the pressing part overcomes the water pressure in the second water passage.

[0009] As a further improvement, the water-passing body is formed into a cylindrical structure with the active channel, and the cylindrical structure has a vent on the side away from the switching shaft; the piston is configured as a conical head that is movably inserted into the cylindrical structure to reduce air resistance when pushed.

[0010] As a further improvement, a spring is provided between the conical head and the end of the water-passing body, and the switching shaft is held in the initial position by the elastic force so that water flows out along the second outlet; and the conical head is fitted with a number of sealing rings on the side adjacent to the switching shaft.

[0011] As a further improvement, in the initial position, the water inlet is connected to the inlet of the second water channel; the pressing part can be operably driven to switch the switching shaft from the initial position to the use position, where the water inlet is connected to the inlet of the first water channel.

[0012] As a further improvement, a through hole connecting to the second water passage is opened on the side of the switching shaft, and the water inlet and the through hole are connected in the initial position.

[0013] As a further improvement, at the usage position, the through hole and the water inlet are not connected. At this time, a flow channel is formed between the switching shaft and the water-passing body to connect the water inlet and the first water path.

[0014] As a further improvement, a stop component is also provided on the switching shaft; the water-passing body is provided with a stop groove that cooperates with the stop component, and the position state of the switching shaft is defined by guiding the relative position of the stop component in the stop groove.

[0015] As a further improvement, the shift groove is constructed as an irregular arc-shaped hook groove, which allows the shift member to switch from the first shift position to the second shift position after one press, and allows the shift member to switch back to the first position after the second press.

[0016] This application also provides a shower head, including a shower head body and a water outlet switching device disposed on the shower head body.

[0017] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0018] 1. The labor-saving water outlet switching device of this application has a piston part of the switching shaft that is adapted to be inserted into the movable channel of the water-passing body. The user only needs to press to drive the switching shaft to switch positions freely. The piston part further achieves sealing and isolation in the movable channel, so that the switching shaft can effectively switch the water outlets of the first water path and the second water path to their respective outlets. It more efficiently overcomes the frictional resistance under high water pressure environment, reduces the pressing torque required for operation, reduces the labor intensity of the user, and ensures a smooth and stable operation process.

[0019] 2. The sealing effect of the piston in the moving channel ensures reliable isolation of the first water path during switching, preventing water flow interruption or mixing. The first water outlet located on the main water body and the second water outlet located on the switching shaft achieve two different water spray effects. Users can choose the appropriate water outlet mode according to actual needs or usage scenarios, making the water outlet effect more aesthetically pleasing and adaptable, meeting diverse usage needs. Through the coordinated arrangement of the water channel component, switching component, and water outlet component, its structure is simpler and more compact, which not only helps to reduce production costs and assembly difficulty, but also facilitates daily use and maintenance, improving the overall reliability and durability of the product.

[0020] 3. In particular, the piston part prevents water from entering the active channel, so that the piston part will not be subjected to direct water pressure during the pressing and switching process. Water enters from the inlet to the second water channel along the side and is transmitted from the second water channel in the switching shaft body. At this time, the water pressure in the second water channel is lower than the direct water pressure, so the required pressing force is smaller, which significantly improves the user experience.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. Example

[0030] Combination Figures 1 to 7 This embodiment provides a labor-saving water outlet switching device, including a water channel assembly 1, a switching assembly 2, and a water outlet assembly 3. The water channel assembly 1 has a water-passing body 11, which includes at least an inlet 12, a first outlet 13, a movable channel 14, and a first water passage connecting the inlet 12 and the first outlet 13. The switching assembly 2 includes a switching shaft 21, a piston portion 22 formed at one end of the switching shaft 21, and a pressing portion 23 formed at the other end of the switching shaft 21. A second outlet 24 is correspondingly provided on the switching assembly 2, and a second water passage connecting the second outlet 24 is provided inside the switching shaft 21.

[0031] The water outlet assembly 3 includes a first water outlet component 31 connected to the first water outlet 13 to form one type of water spray, and a second water outlet component 32 connected to the second water outlet 24 to form another type of water spray. The water inlet 12 allows water to enter laterally into the second water passage. The piston part 22 is movably and sealed within the movable channel 14, which isolates the movable channel from the first and second water passages. During the pressing and switching process, the piston part 22 is protected from direct water pressure within the movable channel 14, thereby making it easier to manually drive the switching shaft 21 to select either the first water outlet 13 or the second water outlet 24 for water dispensing.

[0032] The aforementioned labor-saving water outlet switching device has a piston part 22 of the switching shaft 21 that is adapted to be inserted into the movable channel 14 of the water-passing body 11. The user only needs to press to drive the switching shaft 21 to switch positions freely. Furthermore, the piston part 22 further achieves sealing and isolation within the movable channel 14, thereby enabling the switching shaft 21 to effectively switch the water outlets of the first and second water paths to their respective outlets. This more efficiently overcomes the frictional resistance under high water pressure, reduces the pressing torque required for operation, reduces the user's labor intensity, and ensures a smooth and stable operation process.

[0033] The sealing effect of the piston part 22 within the movable channel 14 ensures reliable isolation of the first water path during switching, preventing water flow interruption or mixing. The first water outlet 13 located on the water-passing body 11 and the second water outlet 24 located on the switching shaft 21 respectively achieve two different water splash effects. Users can select the appropriate water outlet mode according to actual needs or usage occasions, thereby making the water outlet effect more aesthetically pleasing and adaptable, meeting diverse usage needs. Thus, through the coordinated arrangement of the water channel component 1, the switching component 2, and the water outlet component 3, the structure is simpler and more compact, which not only helps to reduce production costs and assembly difficulty, but also facilitates daily use and maintenance, improving the overall reliability and durability of the product.

[0034] In particular, the piston part 22 prevents water from entering the active channel 14, so that the piston part 22 will not be subjected to direct water pressure during the pressing and switching process. Water enters from the inlet 12 laterally to the second water channel and is transmitted through the second water channel in the switching shaft 21. At this time, the water pressure in the second water channel is lower than the direct water pressure, so the required pressing force is smaller, which significantly improves the user experience.

[0035] In this embodiment, the movable channel 14 is connected to the outside, allowing the piston part 22 to be inserted into the movable channel 14 and freely switch positions. The cross-section of the second water path is smaller than that of the movable channel. When pressing to switch to the first outlet for water dispensing, the pressing part overcomes the water pressure in the second water path. Therefore, when switching water paths, only the water pressure in the smaller cross-section second water path needs to be overcome, enabling a quick and effective pressing operation, which is more labor-saving and convenient.

[0036] like Figure 4 and Figure 5 As shown, in this embodiment, the water-passing body 11 is formed into a cylindrical structure with the movable channel 14. A vent 15 is provided on the side of the cylindrical structure away from the switching shaft 21. When the piston 22 moves relative to the movable channel 14, the vent 15 allows air inside the cylindrical structure to be promptly expelled or replenished during movement, avoiding air stagnation and ensuring smooth operation of the piston 22 within the movable channel 14, facilitating easier operation of the pressing part 23. Clearly, the vent 15 significantly reduces the additional resistance caused by negative pressure or excessively high air pressure inside the cylinder, making the movement of the switching shaft 21 within the movable channel 14 smoother and effectively reducing the force required for operation.

[0037] Furthermore, the piston portion 22 is configured as a conical head suitable for movably inserting into the cylindrical structure to reduce air resistance during actuation. Understandably, the conical head's design helps guide air smoothly out, significantly reducing air resistance when the piston is actuated, making the switching operation easier and smoother. Due to the reduced air resistance, the user requires less torque to press the switching component 2, resulting in more sensitive operational feedback, thus achieving effortless operation, a better user experience, and higher transmission efficiency.

[0038] A spring 25 is provided between the conical head and the end of the water-passing body 11. The switching shaft 21 is held in its initial position by the spring force so that water can flow out through the second outlet 24. The spring force provided by the spring 25 keeps the switching shaft 21 in its initial position, ensuring that the water outlet device always flows out through the second outlet 24 when there is no external force intervention. This realizes the automatic reset function, ensures the stability of the water output, and improves the safety and reliability of the overall operation.

[0039] The conical head has multiple sealing rings 26 fitted on one side adjacent to the switching shaft 21. Preferably, each sealing ring 26 is spaced apart on the outer periphery of the conical head and tightly fitted to the inner wall of the movable channel 14, thereby effectively enhancing the sealing effect between the conical head and the switching shaft 21. During water flow switching, the sealing rings 26 can prevent water leakage or leakage caused by water pressure changes, further ensuring the accuracy and stability of water flow switching.

[0040] In the initial position, the water inlet 12 is connected to the inlet of the second water path. The pressing part 23 can be operably driven to switch the switching shaft 21 from the initial position to the usage position, where the water inlet 12 is connected to the inlet of the first water path. The user only needs to apply appropriate operating force through the pressing part 23 to make the switching shaft 21 move smoothly from the initial position to the usage position, realizing rapid switching of water paths. By switching water paths in different positions, two different water output modes can be provided according to user needs, which not only enriches the water output effect but also expands the adaptability of the device in various usage scenarios, such as energy-saving mode, powerful rinsing, or fine spray, etc.

[0041] Specifically, a through hole 27 connecting to the second water passage is provided on the side of the switching shaft 21 or piston part 22. In the initial position, the water inlet 12 is connected to the through hole 27 for water intake. At this time, the water flow input from the outlet enters the second water passage through the through hole 27, and is output to the second outlet 24 and the second water outlet 32 ​​through the second water passage. The second water outlet 32 ​​is inclined relative to the switching shaft 21 for water output.

[0042] Correspondingly, at the usage position, the through hole 27 and the inlet 12 are not connected (they are misaligned). At this time, a flow channel is formed between the switching shaft and the water-passing body 11 to connect the inlet 12 and the first water path. At this time, the water input from the outlet enters the first water path along the flow channel, and is transmitted through the first water path to the first outlet 13 and the first water outlet component 31 within the water-passing body 11, thereby vertically discharging water along the side of the water-passing body 11.

[0043] like Figure 6 and Figure 7 As shown, in this embodiment, the water outlet device further includes a stop member 28 disposed on the switching shaft 21. The water-passing body 11 is correspondingly provided with a stop groove 16 that cooperates with the stop member 28. By guiding the relative position of the stop member 28 within the stop groove 16, the position state of the switching shaft 21 is correspondingly defined. It should be noted that when the stop member 28 moves within the stop groove 16, it provides intuitive mechanical feedback to the user, allowing the user to clearly perceive the positional change of the switching shaft 21. By clearly defining the various positional states of the switching shaft 21, abnormal water circuit switching caused by improper operation can be effectively prevented in actual use, avoiding water flow interruption or mixing, thereby ensuring stable switching between different water outlet modes.

[0044] Furthermore, the gear shift groove 16 is constructed as an irregular arc-shaped hook groove, which, upon a single press, allows the gear shift member 28 to shift from the first gear to the second gear, and upon the next press, allows it to shift the gear shift member 28 back to the first position from the second position. By employing an arc-shaped hook groove structure to achieve bidirectional gear shifting, the overall structure is simplified, the complexity of moving parts is reduced, thereby lowering wear and failure rates. It should be understood that other positioning or locking methods can also be used for gear shifting, and no limitation is made here.

[0045] In addition, this embodiment provides a shower head, including a shower head body and a water outlet switching device disposed on the shower head body for effortless switching.

[0046] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are within the protection scope of this utility model.
