Description

Technical Field

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

[0002] Traditional showerheads typically use physical buttons or rotary switches to switch between different water output modes (such as rain shower, massage shower, spray shower, etc.). The switch drives the adjustment plate to rotate, and when the through holes on the adjustment plate are aligned with the different water outlets on the water distribution plate, the different water output modes can be switched.

[0003] However, due to structural limitations, users often need to apply a certain amount of force to overcome the friction between mechanical parts when switching water modes. This not only makes the operation less smooth, but also causes the buttons to stick when switching after a long period of use, affecting the user experience. Utility Model Content

[0004] To solve the above problems, this utility model provides the following technical solution:

[0005] A water outlet switching mechanism includes a main body fixed inside a shower head. An adjusting plate and a ratchet are rotatably connected to the main body. A rotating shaft is disposed inside the main body. The ratchet and the adjusting plate are both fixed on the rotating shaft and rotate synchronously with the rotating shaft. A gear that rotates relative to the rotating shaft is also sleeved on the rotating shaft. A driving pawl protrudes from the gear and abuts against the tooth groove of the ratchet. A driving rod is movably disposed inside the main body. A rack that meshes with the gear is disposed at one end of the driving rod. An operating component for driving the driving rod to move is disposed on the main body. A return spring is disposed between the driving rod and the main body. When the operating component drives the driving rod to move, the driving pawl drives the ratchet to rotate. When the return spring drives the driving rod to return to its original position, the driving pawl rotates along the ratchet.

[0006] The present invention is further configured such that: a one-way pawl is fixed on the main body, and the one-way pawl abuts against the tooth groove of the ratchet.

[0007] The present invention is further configured such that: the operating component includes a button and a swing block, one end of the button is hinged to the main body, the middle part of the swing block is hinged between the button and the drive rod, one end of the swing block is used to contact the movable end of the button, and the other end is used to contact the drive rod.

[0008] The present invention is further configured such that: the operating component includes a slider and a connecting rod, the slider is slidably connected to the main body, one end of the connecting rod is fixed to the driving rod, and the other end is used to contact the slider.

[0009] The present invention is further configured such that: the gear is sleeved on the rotating shaft and located above the ratchet, and the driving pawl is fixed to the bottom of the gear.

[0010] The present invention is further configured such that: the rack is located on one side of the gear, and the return spring is disposed on the main body and close to the rack.

[0011] The present invention is further configured such that: a first guide post is provided inside the main body, a second guide post is provided on the drive rod, and the two ends of the reset spring are respectively sleeved on the first guide post and the second guide post.

[0012] The present invention is further configured such that: a slide rail is provided on the drive rod in the horizontal direction, and a convex strip protrudes from the main body toward the slide rail, and the drive rod slides along the convex strip.

[0013] In addition, this utility model also proposes a shower head, including the above-mentioned water outlet switching mechanism. The shower head is provided with a water distribution plate, the adjustment plate is provided with an adjustment hole, and the water distribution plate is provided with a plurality of water outlet holes. When the rotating shaft drives the adjustment plate to rotate to different angles, the adjustment hole aligns with different water outlet holes, thereby achieving different water outlet effects.

[0014] Compared with the prior art, the present invention has at least the following advantages:

[0015] 1. When the user moves the drive lever by operating the component, the rack at the end of the drive lever drives the gear to rotate. The drive pawl on the gear drives the ratchet to rotate in the same direction, thereby driving the adjustment plate to rotate and switch the water outlet mode. After the operation is completed, the reset spring pushes the drive lever to reset, the rack drives the gear to rotate back, and at this time the drive pawl will slide over the ratchet as it rotates, and the ratchet will not follow its rotation. This application relies on rack and gear transmission, which has the characteristics of high efficiency, high stability, and smooth movement. Combined with the ratchet and pawl structure, it achieves smooth and stable water outlet switching.

[0016] 2. By fixing a one-way ratchet to the main body and engaging it with the ratchet's teeth, it can only rotate in one direction. When the drive pawl resets and slides over the ratchet, friction is avoided from causing the ratchet to rotate, making the water output switching more accurate and stable.

[0017] 3. By setting the return spring to one side, the return spring is closer to the rack, making the spring force more efficient and the mechanism more stable. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0028] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] First embodiment:

[0030] A water outlet switching mechanism, such as Figures 1 to 3As shown, the shower head 17 includes a main body 1 fixed inside the shower head 17. An adjusting plate 2 and a ratchet 3 are rotatably connected to the main body 1. A rotating shaft 4 is provided inside the main body 1. Both the ratchet 3 and the adjusting plate 2 are fixed on the rotating shaft 4 and rotate synchronously with the rotating shaft 4. The adjusting plate 2 has an adjusting hole. By rotating the adjusting plate 2 to different angles, the adjusting hole is aligned with different water outlet holes on the water distribution plate 18, thereby achieving the switching of different water outlet modes.

[0031] A gear 5 that rotates relative to the rotating shaft 4 is also fitted on the rotating shaft 4. A drive pawl 6 protrudes from the gear 5 and abuts against the tooth groove of the ratchet 3. A drive rod 7 is movably arranged inside the main body 1. A rack 8 that meshes with the gear 5 is provided at one end of the drive rod 7. An operating component for driving the drive rod 7 to move is provided on the main body 1. A return spring 9 is provided between the drive rod 7 and the main body 1. When the operating component drives the drive rod 7 to move, the ratchet 3 is driven to rotate through the drive pawl 6, thereby driving the adjusting plate 2 to rotate to realize the water outlet switching. After the operation is completed, the return spring 9 will drive the drive rod 7 to return to its original position. At this time, the drive pawl 6 will slide over the ratchet 3 as it rotates along with the ratchet 3, and the ratchet 3 will not follow the rotation.

[0032] A one-way pawl 10 is fixed on the main body 1. The one-way pawl 10 abuts against the tooth groove of the ratchet 3, further restricting the one-way rotation of the ratchet 3. When the drive pawl 6 is reset and rotated, it slides over the ratchet 3 and holds the ratchet 3 in place by the one-way pawl 10, thereby preventing the friction between the drive pawl 6 and the ratchet 3 from causing the ratchet 3 to rotate, making the water outlet switching more accurate, thorough and stable.

[0033] The operating components of this embodiment include a button 11 and a swing block 12. One end of the button 11 is hinged to the main body 1, and the middle part of the swing block 12 is hinged between the button 11 and the drive rod 7. One end of the swing block 12 is used to contact the movable end of the button 11, and the other end is used to contact the drive rod 7. By pressing the movable end of the button 11 inward, the user causes the swing block 12 to rotate toward the drive rod 7, thereby pushing the drive rod 7 to move and switch the water output. When the reset spring 9 drives the drive rod 7 to reset, it will also cause the swing block 12 to rotate toward the button 11, causing the button 11 to rotate outward and reset.

[0034] In this embodiment, gear 5 has tooth blocks on only one side of its circumference. Gear 5 is sleeved on shaft 4 and located above ratchet 3. The top of shaft 4 has a barb that engages with the upper surface of gear 5, limiting gear 5 in the vertical direction to prevent it from falling off. Drive pawl 6 is fixed to the bottom of gear 5, making drive pawl 6 and ratchet 3 closer to the same horizontal plane. Specifically, there are protrusions on the circumference of gear 5, drive pawl 6 is fixed to the bottom of the protrusions, and drive pawl 6 is inclined toward the tooth groove direction of ratchet 3.

[0035] The rack 8 is located on the side of the gear 5 with teeth, and the return spring 9 is set on the main body 1 and close to the rack 8. That is, the ratchet 3 and the button 11 are both located on the center line of the shower head 17, and the return spring 9 is located on the center line of the shower head 17 close to the rack 8. This makes the return spring 9 closer to the rack 8, with higher elasticity and more stable operation of the mechanism.

[0036] The main body 1 is provided with a first guide post, and the drive rod 7 is provided with a second guide post. The first guide post and the second guide post are arranged along the moving direction of the drive rod 7 and in the horizontal front-back direction. The two ends of the return spring 9 are respectively sleeved on the first guide post and the second guide post to limit the moving trajectory of the return spring 9 so that it is not easy to bend or fall off when it moves.

[0037] The drive rod 7 has a slide rail 15 along the horizontal direction. Specifically, there are slide rails 15 on both the left and right sides of the drive rod 7. The inner wall of the main body 1 has a protruding strip 16 protruding into the slide rail 15. The drive rod 7 slides along the protruding strip 16 to realize the sliding connection between the drive rod 7 and the main body 1, and to restrict the drive rod 7 from moving back and forth in the horizontal direction.

[0038] The working process of this utility model is as follows:

[0039] When it is necessary to switch the water outlet mode, the user presses the button 11 inward, and the swing block 12 pushes the drive rod 7 forward. The rack 8 at the end of the drive rod 7 drives the gear 5 to rotate, and the drive pawl 6 on the gear 5 will push the ratchet 3 to rotate in the same direction, thereby driving the adjustment plate 2 to rotate and switch the water outlet mode. After the operation is completed, the reset spring 9 will push the drive rod 7 to reset, and the rack 8 will drive the gear 5 to rotate. At this time, the drive pawl 6 will slide over the ratchet 3 as it rotates, and the ratchet 3 will not follow the rotation. It is also engaged by the one-way pawl 10, so that the water outlet mode switching is more precise and thorough.

[0040] Second embodiment:

[0041] A water outlet switching mechanism, such as Figure 4 As shown, the difference from the first embodiment is that the operating component includes a slider 13 and a connecting rod 14. The slider 13 is slidably connected to the main body 1. One end of the connecting rod 14 is fixed to the drive rod 7, and the other end is used to contact the slider 13. The connecting rod 14 and the drive rod 7 are integrally formed. The user pushes the slider 13 to drive the drive rod 7 to move forward.

[0042] The remaining undescribed parts are the same as in the first embodiment and will not be repeated here.

[0043] Third embodiment:

[0044] A type of shower head, such as Figures 5 to 7As shown, the water outlet switching mechanism described in the first or second embodiment is included. The main body 1 is locked inside the shower head 17 by screws. Water enters the water outlet switching mechanism from the tail end of the shower head 17, and after passing through the adjustment plate 2 and the water distribution plate 18, it is sprayed out from the nozzle on the water outlet panel 19.

[0045] The shower head 17 has a water distribution plate 18 inside, and an adjustment hole 20 is provided on the adjustment plate 2. The water distribution plate 18 has several water outlet holes 21. When the water outlet switching mechanism drives the adjustment plate 2 to rotate to different angles through the rotating shaft 4, the adjustment hole 20 is aligned with the water outlet holes 21 at different angles. The several water outlet holes 21 correspond to various water outlet effects, thereby achieving different water outlet effects.

[0046] In this embodiment, when the adjusting plate 2 is rotated to the water outlet position (state 1), water flows through water channel 1 to produce particulate water; when the adjusting plate 2 is rotated to the water outlet position (state 2), water flows through water channel 2 to produce shower water; when the adjusting plate 2 is rotated to the water outlet position (state 3), water flows through water channel 3 to produce pressurized shower water. Similarly, the product structure and switching mechanism can be designed with multiple water channels and multiple angles for water inlet switching to achieve more functions.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
