Description

Technical Field

[0001] This utility model relates to the field of shower heads, and in particular to a shower head with a pause water structure. Background Technology

[0002] Currently, in order to improve user convenience, shower heads with a pause function have appeared on the market. These shower heads are equipped with operating components, which users can use to control the water flow to start or stop, making them quite convenient to use.

[0003] A current type of showerhead with a pause function has a rotatable pause component inside the water inlet chamber of the showerhead body. The pause component has a pause section on its side, which movably blocks the water inlet of the water inlet chamber. An operating component drives the pause component to rotate. When the pause section blocks the water inlet, water from the water inlet of the water inlet flows out through the gap between the pause section and the inner wall of the water inlet chamber, resulting in a micro-flow of water (i.e., a very small water volume, the water from the showerhead is not jet-like). At this time, the showerhead is in a paused water flow state. Because the pause section of the pause component completely covers the water inlet when blocking it... This causes all the water flowing out of the inlet of the water inlet chamber to flow out through the gap between the pause section and the inner wall of the water inlet chamber. This results in a large force on the side of the pause section of the pause component, requiring the user to exert a lot of force to operate the control components to release the pause component from the water inlet, affecting the user experience. In addition, in order to ensure that the shower head provides a micro-flow of water when the water is paused, the gap between the pause section and the inner wall of the water inlet chamber needs to be strictly controlled. This places high demands on the manufacturing and installation precision of the pause component. If the manufacturing and / or installation precision of the pause component is insufficient, problems such as the pause component getting stuck or unable to rotate may easily occur.

[0004] In view of the above problems, it is necessary to study a shower head with a pause water flow structure that allows users to control the shower head to switch from a paused water flow state to an on water flow state with minimal effort, and with low requirements for the manufacturing and installation precision of the pause component. Utility Model Content

[0005] The purpose of this utility model is to provide a shower head water pause structure, which allows users to control the shower head from paused water flow to on water flow with minimal effort, and has low requirements for the manufacturing and installation precision of the pause component.

[0006] To achieve the above objectives, the solution of this utility model is: A water-stopping structure for a shower head, the shower head having a water inlet chamber, a rotatable water-stopping component disposed in the water inlet chamber, and an operating component for driving the water-stopping component to rotate; the water-stopping component has a water-stopping channel and a water-outlet notch, the water-stopping channel and the water-outlet notch being movably connected to the water inlet of the water inlet chamber, the water-stopping channel having a water-stopping inlet and a water-stopping outlet, the water-stopping inlet being movably connected to the water inlet of the water inlet chamber, and the diameter of the water-stopping outlet being smaller than the diameter of the water-stopping inlet.

[0007] The water inlet chamber includes an inlet chamber and an outlet chamber. The peripheral wall of the inlet chamber is provided with an inlet for the water inlet chamber, and one end of the inlet chamber is connected to the outlet chamber. The pause component includes a pause body and a sealing body that cooperates with the pause body. The pause body is provided with a pause water channel and an outlet notch. The pause water channel and the outlet notch are located inside the inlet chamber, and the pause outlet of the pause water channel and the outlet notch are connected to the outlet chamber. The sealing body movably abuts against the peripheral wall of the inlet chamber. The sealing body is provided with a through-hole that communicates with the pause inlet and is movably connected to the inlet of the inlet chamber. The diameter of the pause outlet is smaller than the diameter of the through-hole.

[0008] The sealing body has a ring that extends into the paused waterway.

[0009] The shower head also has multiple water outlet chambers; a rotatable water distribution plate is fitted inside the water inlet chamber, and the water distribution plate controls the water inlet chamber to selectively connect to each water outlet chamber; the pause component is driven by the water distribution plate, and the operating component is driven by the water distribution plate.

[0010] The pause component engages with the water distribution plate.

[0011] The operating components include a ratchet, pawl, push rod, button, and return spring that are fitted to the shower body; the ratchet and pawl are rotatable in the shower body, with the pawl engaging the ratchet teeth of the ratchet in one direction, and the ratchet is connected to the water distribution plate via a connecting shaft; the push rod is movably fitted to the shower body, and is movably fitted to the ratchet to drive the ratchet to rotate in one direction; the button is movably fitted to the shower body, and is kinetically fitted to the push rod to push the push rod to move; the return spring is disposed between the shower body and the push rod and is used to drive the push rod to return to its original position; the shower body has the inlet chamber and each outlet chamber.

[0012] The push rod is fitted with a push block. The push rod has a lateral mounting groove. The push block slides into the lateral mounting groove and moves to push against each tooth of the ratchet.

[0013] The shower head body is provided with a guide groove, and the guide groove is provided with a guide arc surface. The center of the guide arc surface and the center of the ratchet are on the same axis. The push block is provided with a guide post that moves against the guide arc surface, and a push block spring that is fitted in the lateral mounting groove against the push block.

[0014] A protrusion is provided on one side of the push rod, and a protruding post is formed on the protrusion; a stop block is provided on the shower body, and the stop block has a stop groove; the two ends of the return spring support the protrusion and the stop block respectively, one end of the return spring is fitted with the protruding post, and the other end of the return spring is inserted into the stop groove.

[0015] The operating component also includes a swing block. The button is driven by the swing block and the push rod. The swing block is hinged to the shower head body. One end of the swing block abuts against the button, and the other end of the swing block abuts against the end of the push rod.

[0016] With the above solution, the working principle of this utility model is as follows: When the user controls the pause component to rotate until the pause inlet of the pause channel of the pause component is connected to the inlet of the water inlet chamber, the shower head is in a paused water output state. The water flow input from the inlet is input into the water inlet chamber through the pause channel. Since the aperture of the pause outlet of the pause channel is smaller than the aperture of the pause inlet, a small flow of water flows out of the pause outlet into the water inlet chamber, causing the pause component to be subjected to force inside and outside, thereby making the pause component subjected to force evenly and easy to rotate. Afterwards, the user can easily control the pause component to rotate until the water outlet of the pause component is connected to the inlet of the water inlet chamber through the pause channel, so that the water flow input from the inlet is input into the water inlet chamber, and the shower head is in a turned-on water output state.

[0017] In addition, when the shower head is in the paused water flow state, the water flow entering the inlet is introduced into the inlet chamber through the pause water channel of the pause component. This eliminates the need to consider the gap requirements between the pause component and the inlet chamber, effectively reducing the requirements for the manufacturing and installation accuracy of the pause component.

[0018] As can be seen from the above, this utility model enables users to effortlessly switch the shower head from a paused water flow state to an on water flow state, and has low requirements for the manufacturing and installation precision of the pause component. Attached Figure Description

[0031] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0032] like Figures 1 to 11As shown, this utility model discloses a water-stopping structure for a shower head. The shower head has a water inlet chamber 11, a rotatable water-stopping component 2 disposed in the water inlet chamber 11, and an operating component 3 for driving the water-stopping component 2 to rotate. The water-stopping component 2 has a water-stopping channel 211 and a water-outlet 212, which are movably connected to the water inlet 110 of the water inlet chamber 11. The water-stopping channel 211 has a water-stopping inlet 2111 and a water-stopping outlet 2112. The water-stopping inlet 2111 is movably connected to the water inlet 110 of the water inlet chamber 11, and the diameter of the water-stopping outlet 2112 is smaller than the diameter of the water-stopping inlet 2111.

[0033] The working principle of this utility model is as follows: When the user controls the pause component 2 to rotate through the operating component 3 until the pause inlet 2111 of the pause channel 211 of the pause component 2 is connected to the inlet 110 of the inlet chamber 11, the shower head is in a paused water output state. The water flow input from the inlet 110 is input into the inlet chamber 11 through the pause channel 211. Since the aperture of the pause outlet 2112 of the pause channel 211 is smaller than the aperture of the pause inlet 2111, a small flow of water flows out of the pause outlet 2112 into the inlet chamber 11, so that the pause component 2 is subjected to internal and external forces, thereby making the pause component 2 subjected to balanced forces and easy to rotate. After that, the user can easily control the pause component 2 to rotate through the operating component 3 until the outlet notch 212 of the pause component 2 is connected to the inlet 110 of the inlet chamber 11, so that the water flow input from the inlet 110 is input into the inlet chamber 11 through the outlet notch 212, so that the shower head is in an open water output state. Furthermore, when the shower head is in the paused water flow state, the water flow input from the inlet 110 is input into the inlet chamber 11 through the pause water channel 211 of the pause component 2. This eliminates the need to consider the gap requirement between the pause component 2 and the inlet chamber 11, effectively reducing the requirements for the manufacturing and installation accuracy of the pause component 11.

[0034] In an embodiment of this utility model, the water inlet chamber 11 may include an inlet chamber 111 and an outlet chamber 112. The inlet chamber 111 may be a cylindrical structure, and the peripheral wall of the inlet chamber 111 is provided with an inlet 110. One end of the inlet chamber 111 communicates with the outlet chamber 112. The pause component 2 includes a pause body 21 and a sealing body 22 that cooperates with the pause body 21. The pause body 21 is provided with a pause water channel 211 and an outlet notch 212. The pause water channel 211 and the outlet notch 212 are located at the water inlet. Inside chamber 111, the pause outlet 2112 and water outlet 212 of the pause water channel 211 are connected to the water outlet chamber 112; the sealing body 22 movably abuts against the peripheral wall of the water inlet chamber 111, and the sealing body 22 is provided with a water passage 221 that communicates with the pause inlet 2111. The water passage 221 is movably connected to the water inlet 110 of the water inlet cavity 11, and the diameter of the pause outlet 2112 is smaller than the diameter of the water passage 221; when the shower head is in the paused water outlet state, because the diameter of the pause outlet 2112 is smaller than the diameter of the water inlet 110, the paused water outlet 2112 is connected to the water outlet 110. The water pressure at the pause outlet 2112 is greater than the water pressure at the inlet 110 (the water pressure at the pause outlet 2112 is also greater than the water pressure at the outlet 221). Under this pressure difference, the sealing body 22 is forced to move towards the inlet 110, causing it to press against the peripheral wall of the inlet chamber 111. This allows the sealing body 22 to seal the pause channel 211 against the inlet 110, ensuring that all water from the inlet 110 flows into the pause channel 211. In other words, water can only flow through the pause outlet 2112. The system enables a pause function. The pause body 21 may have a groove 213 into which the sealing body 22 is fitted. Furthermore, the sealing body 22 may have an annular piece 222 extending into the pause water channel 211. When the showerhead is in the paused water flow state, the water flowing into the pause water channel 211 backflows around the pause outlet 2112, applying pressure to the annular piece 222 of the sealing body 22. This allows the annular piece 222 of the sealing body 22 to form a tight seal with the pause body 21, ensuring a good seal between the sealing body 22 and the pause body 21. Additionally, the inlet end of the pause outlet 2112 may form a narrowing section 2113 with a gradually decreasing diameter along the water flow direction to facilitate smooth water flow into the pause outlet 2112.

[0035] In this embodiment of the present invention, the shower head further has multiple water outlet chambers 12, each water outlet chamber 12 and the water inlet chamber 11 being disposed in the shower head body 1, the shower head body 1 being installed in the shower head housing 4; and a rotatable water distribution plate 5 is fitted inside the water outlet chamber 112 of the water inlet chamber 11, the water distribution plate 5 controlling the water outlet chamber 112 of the water inlet chamber 11 to selectively connect to each water outlet chamber 12, thereby realizing the water outlet switching function; and the pause body 21 of the pause component 2 is drivenly engaged with the water distribution plate 5, and the operating component 3 is connected to the water distribution plate 5. The transmission mechanism allows the user to control the pause element 2 and the water distribution plate 5 through a single operating component 3, achieving integrated settings. Furthermore, when the pause inlet 2111 of the pause water channel 211 is connected to the inlet 110 of the water inlet chamber 11 (i.e., when the shower head is in a paused water flow state), the water distribution plate 5 controls the water outlet chamber 112 of the water inlet chamber 11 to connect with at least one of the various water outlet chambers 12, ensuring that water from the pause water channel 211 flows out through at least one water outlet chamber 12, thus achieving a micro-flow of water from the shower head. The structure of the water distribution plate 5 controlling the selective connection of the water outlet chamber 112 of the water inlet chamber 11 to each water outlet chamber 12 is existing technology and will not be elaborated upon here.

[0036] In an embodiment of this utility model, the pause body 21 of the pause member 2 meshes with the water distribution plate 5, so that the pause member 2 and the water distribution plate 5 rotate synchronously.

[0037] In an embodiment of this utility model, the operating component 3 may include a ratchet 31, a pawl 32, a push rod 33, a button 34, and a return spring 35 that are fitted to the shower body 1. The ratchet 31 and pawl 32 are rotatable on the shower body 1, and the pawl 32 engages unidirectionally with the ratchet teeth of the ratchet 31. The ratchet 31 is connected to the water distribution plate 5 via a connecting shaft 6. The push rod 33 is translatably fitted to the shower body 1, and is movably fitted to the ratchet 31 to drive the ratchet 31 to rotate unidirectionally. The button 34 is movably fitted to the shower body 1, and is kinetically fitted to the push rod 33 to push the push rod 33 to move. The return spring 35 is disposed between the shower body 1 and the push rod 33 and is used to drive the push rod 33 to return to its original position. The user drives the push rod 33 to move by pressing the button, and the push rod 33 then drives the ratchet 31 to rotate unidirectionally. The ratchet 31 drives the water distribution plate 5 to rotate, and the water distribution plate 5 drives the stop member 2 to rotate.

[0038] In an embodiment of this utility model, the push rod 33 is fitted with a push block 36. The push rod 33 has a lateral mounting groove 331. The push block 36 slides into the lateral mounting groove 331 and the push block 36 movably pushes against the ratchet teeth of the ratchet 31. When the push rod 33 moves, the push rod 33 drives the push block 36 to abut against the ratchet teeth of the ratchet 31, thereby driving the ratchet 31 to rotate. In addition, the shower body 1 may be provided with a guide groove 13. The guide groove 13 has a guide arc surface 131. The center of the guide arc surface 131 and the center of the ratchet 31 are on the same axis. The push block 36 has a guide post 361 that movably abuts against the guide arc surface 131. A push block spring 37 in the lateral mounting groove 331 abuts against the push block 36, so that the guide post 361 of the push block 36 keeps in contact with the guide arc surface 131. During the movement of the push block 36, because the guide post of the push block 36 abuts against the guide arc surface 131, the guide arc surface... 131 can guide the push block 36, causing the push block 36 to move along the guide arc surface 131. This allows the push block 36 to apply a force to the ratchet 31 along the guide arc surface 131 (i.e., the push block 36 applies a force to the ratchet 31 tangentially). In this way, the guide arc surface 131 can allow the push block 36 to engage the ratchet teeth of the ratchet 31 and drive the ratchet 31 to rotate. It can also prevent the force applied by the push block 36 to the ratchet 31 from being radial to the ratchet 31, thereby preventing the ratchet 31 from jamming.

[0039] In an embodiment of this utility model, a protrusion 332332 is provided on one side of the push rod 33, and a protruding post 3321 is formed on the protrusion 332332; the shower body 1 is provided with a stop block 14, and the stop block 14 is provided with a stop groove 141; the two ends of the return spring 35 respectively support the protrusion 332332 and the stop block 14, one end of the return spring 35 is sleeved on the protruding post 3321, and the other end of the return spring 35 is inserted into the stop groove 141, which can effectively prevent the return spring 35 from falling off.

[0040] In an embodiment of this utility model, the operating component 3 further includes a swing block 38. The button 34 is driven to cooperate with the push rod 33 through the swing block 38. The swing block 38 is hinged to the shower body 1. One end of the swing block 38 abuts against the button 34, and the other end of the swing block 38 abuts against the end of the push rod 33. In this way, the button 34 can drive the push rod 33 to move through the swing block 38.

[0041] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
