Description

Technical Field

[0001] This utility model relates to the field of kitchen and bathroom products, and in particular to a mouthwash water outlet structure and a pull-out shower head. Background Technology

[0002] Pull-out showerheads are typically installed in sinks or bathrooms to provide flexible water usage for washing hair, face, or cleaning the toilet. Designed to offer a better user experience, pull-out showerheads work in conjunction with faucets, making them convenient for use in various situations. In recent years, with technological advancements and increasing consumer demands, pull-out showerheads have continuously innovated, adding various water flow modes and functions, such as switching between different water flow modes to a mouthwash function. The flexibility of traditional pull-out showerheads combined with the newly added mouthwash function provides users with a more convenient and hygienic water experience.

[0003] Currently, most mouthwashes have straight water channels. This means that the water pressure is higher as the water flows from the channel to the outlet, resulting in a stronger impact force that is not very gentle on the mouth. Furthermore, the fast flow of the straight water channel significantly reduces the filtration effect, leading to poor mouthwash quality. Utility Model Content

[0004] The purpose of this invention is to provide a mouthwash dispensing structure and a pull-out shower head to solve the aforementioned problems in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model provides a mouthwash water outlet structure, including a mouthwash water outlet body, which includes a mouthwash water channel, a rectifier, a filter device and a nozzle.

[0012] The water path switching device includes a press-to-switch mechanism for switching the water path between the mouthwash water outlet structure and the water outlet component.

[0013] In a preferred embodiment, an end cap is provided at one end of the shower body opposite to the water inlet end. The end cap can move axially along the cavity wall of the shower body, and the end cap has the mouthwash water outlet structure built into it.

[0014] The end cap has a water outlet on its side wall corresponding to the nozzle; the end cap is configured as a switching button for the pressing mechanism.

[0015] In a preferred embodiment, the waterway switching device further includes a switching shaft assembled with the pressing switching mechanism;

[0016] The switching shaft is movable along the axial direction and has a first position and a second position in the direction of movement; the switching shaft is provided with a first water outlet chamber and a second water outlet chamber that are not connected to each other;

[0039] First embodiment, reference Figures 1-2 .

[0040] This embodiment provides a mouthwash water outlet structure, including a mouthwash water outlet body. The outlet body includes a mouthwash water channel 11, a rectifier 12, a filter device 13, and a nozzle 14. A water-saving plate 10 is provided at the inlet of the mouthwash water channel 11 along the water flow direction, and a rectifier 12 is provided at the junction of the mouthwash water channel 11 and the filter device 13. The rectifier 12 is a rectifier screen, and the water-saving plate 10 is a constant flow water-saving plate 10. At least three filter pads are provided in the filter device 13.

[0041] The mouthwash channel 11 and the filter device 13 are positioned at an oblique angle within the water outlet body, meaning there is an angle between the filter device 13 and the mouthwash channel 11, ranging from 15° to 60°. This creates a bend in the water flow, which helps to straighten the flow and improve water filtration.

[0042] In conjunction with the oblique arrangement of the filter device 13, a nozzle 14 is provided on the upper side of the water outlet body, and a buffer section 17 is provided between the nozzle 14 and the filter device 13. A sharp corner structure 18 is provided at the connection between the nozzle 14 and the buffer section 17. The water flow through the buffer section 17 and the sharp corner structure 18 forms a cylindrical transparent laminar water flow. The treatment of the sharp corner structure 18 can make the water form an ice column water jet, which is convenient for rinsing the mouth. The sharp corner structure 18 can also play a role in preventing water splashing.

[0043] like Figure 1 The mouthwash water outlet structure 1 operates as follows: water enters through the mouthwash channel 11, passes through the rectifier 12 for the first stage of flow restriction, then enters the filter device 13 at the oblique bend, passes through at least three filter pads 19 for the second stage of rectification, and finally flows into the buffer section 17. The water then passes through the buffer section 17 and the sharp corner structure 18 for the third stage of rectification and plasticization, forming a cylindrical transparent laminar water flow that is ejected from the nozzle 14.

[0044] Second embodiment, reference Figures 3-8 .

[0045] This embodiment provides a pull-out shower head, such as Figure 3 The showerhead body 5 of the pull-out showerhead includes a water inlet 4, a water outlet component 3, a mouthwash outlet structure 1, and a water path switching device 2. The water outlet component 3 and the mouthwash outlet structure 1 are independent of each other and are arranged axially within the showerhead body 5. The water outlet component 3 can output either shower water or aerator water. The water path switching device 2 is used to switch the water path between the mouthwash outlet structure 1 and the water outlet component 3.

[0046] The water path switching device 2 is arranged axially inside the shower body 5. The water path switching device 2 includes a pressing switching mechanism 21 and a switching shaft 22 connected to the pressing switching mechanism 21. In this embodiment, the pressing switching mechanism 21 adopts a structure of hook 6 and guide groove 7 to realize pressing. As the pressing end 211 of the pressing switching mechanism 21 is pressed, the switching shaft 22 can automatically extend and retract during the pressing and releasing actions.

[0047] When the switching mechanism 21 is pressed, the switching shaft 22 can automatically extend and retract along the axial direction, and has a first position and a second position in the direction of movement. In the first position, the switching shaft 22 switches to correspond with the water outlet component 3, connecting the water path of the water outlet component 3. At this time, the water outlet component 3 dispenses water, while the mouthwash outlet structure 1 does not dispense water. In the second position, the switching shaft 22 switches to correspond with the mouthwash outlet structure 1, connecting the water path of the mouthwash outlet structure 1. At this time, the mouthwash outlet structure 1 dispenses water, while the water outlet component 3 does not dispense water.

[0048] In this embodiment, an end cap 15 is provided at one end of the shower body 5 opposite to the water inlet end 4. The end cap 15 can move axially along the cavity wall of the shower body 5, and a mouthwash outlet structure 1 is built into the end cap 15. The end cap 15 serves as the switching button of the pressing switching mechanism 21. The pressing end 211 of the pressing switching mechanism 21 is assembled with the mouthwash outlet structure 1, and the mouthwash outlet structure 1 is arranged to be able to be pressed inward and outward along the cavity wall 51 of the shower body 5. The end cap serves as the switching button of the pressing switching mechanism 21. The pressing switching mechanism 21 is located at the front end along the water flow direction along the switching shaft 22, and the pressing end 211 is located at the front end of the pressing switching mechanism 21 along the water flow direction.

[0049] The side wall of the end cap 15 is provided with a water outlet 16 corresponding to the nozzle 14. With the pressing setting of the mouthwash water outlet structure 1, the mouthwash water outlet structure 1 is configured to extend or retract along the cavity wall 51 of the shower body 5, and water can be discharged from the outlet 16 when the mouthwash water outlet structure 1 extends. In this embodiment, the pressing function is achieved by combining the hook 6 and guide groove 7 of the pressing switching mechanism 21. To enable the mouthwash outlet structure 1 and the switching shaft 22 to be controlled to extend and retract through the same pressing action, a spring-loaded component is provided between the pressing switching mechanism 2 and the mouthwash outlet structure 1. A hook block 8 is provided in the guide groove 7. When pressing, the hook 6 moves downward along the inclined side of the hook block 8, and then, in conjunction with the side inclined side of the guide groove, it can hook the hook block 8 (first position) or the groove wall (second position) under the action of the spring-loaded component. This ensures that the mouthwash outlet structure 1 and the switching shaft 22 extend and retract synchronously. By moving the hook 6 in the guide groove 7, the pressing of the mouthwash outlet structure 1 can achieve switching between its retracted and extended states. Figure 7 .

[0050] By setting the mouthwash water outlet structure 1 and the switching shaft 22 to extend and retract synchronously, the overall length of the pull-out shower head can be reduced. Furthermore, by hiding the button of the pressing switching mechanism 21 on the mouthwash water outlet structure 1, the moving structure specifically designed for the button can be reduced, thus simplifying the overall structure of the pull-out shower head and ensuring good consistency and aesthetic appeal.

[0051] In conjunction with the mouthwash outlet structure 1 provided in the first embodiment, the outlet 16 of the mouthwash outlet structure 1 is located on the upper side of the end cap 15, and the water is discharged from the upper side. In addition, with the axial telescopic structure of the mouthwash outlet structure 1, the front of the end cap 15 is the pressing interface. The button operation is offset from the outlet 16. In this way, the pressing interface and the outlet 16 do not interfere with each other and are independent of each other. When switching water paths, there will be no water pollution caused by pressing the outlet 16.

[0052] like Figure 6 In this embodiment, the different water path switching structure of the switching shaft 22 is configured such that a first water outlet chamber 23 and a second water outlet chamber 24 are provided on the switching shaft 22 along the axial direction, and the first water outlet chamber 23 and the second water outlet chamber 24 are not connected to each other. The first water outlet chamber 23 provides water outlet for the water outlet component 3, and the second water outlet chamber 24 provides water outlet for the mouthwash water outlet structure 1.

[0053] The water outlet assembly 3 has a side outlet 25 on its side wall, and the second water outlet chamber 24 has a side inlet 26 on its side wall. A side water flow channel 29 is provided between the side outlet 25 and the side inlet 26. The switching mechanism 21 can control the flow or blockage of the side water flow channel 29, controlling the first water outlet chamber 23 to supply water to the water outlet assembly 3 or to the second water outlet chamber 24 through the side water flow channel 29. The second water outlet chamber 24 is directly connected to the mouthwash water channel 11 of the mouthwash water outlet structure 1. After the water enters the second water outlet chamber 24, it can be directly discharged by the mouthwash water outlet structure 1.

[0054] A first blocking section 27 is provided at the junction of the first water outlet chamber 23 and the second water outlet chamber 24. As the switching shaft 22 moves axially, the first blocking section 27 opens or closes the water flow channel 29. To ensure that the water flow is unidirectional when the first water outlet chamber 23 discharges water into the second water outlet chamber 24, a second blocking section 28 is provided at the rear end of the first water outlet chamber 23 opposite to the water flow direction. When the first water outlet chamber 23 discharges water into the second water outlet chamber 24, the second blocking section 28 closes the inlet 31 of the first water outlet device.

[0055] To ensure water tightness, sealing rings 20 are fitted on both the first blocking section 27 and the second blocking section 28. Hollow water channels are provided inside the switching shaft 22 to fit the first water outlet chamber 23 and the second water outlet chamber 24. The first blocking section 27 and the second blocking section 28 are located on the outer wall of the switching shaft 22. The blocking function is achieved by the outer wall of the switching shaft 22 and the sealing rings 20 working together with the shower body 5 and the cavity wall of the switching shaft 22, which are adapted to the diameter of the shower body 5, to form an airtight fit.

[0056] In this embodiment, the water path switching operation for the water outlet component 3 and the mouthwash water outlet structure 1 is as follows:

[0057] like Figure 4 When the water outlet component 3 is in operation, pressing the front of the end cap 15 causes the hook 6 to hook inward onto the hook block 8 in cooperation with the guide groove 7. The mouthwash outlet structure 1 retracts inward into the cavity wall 51 of the shower body 5 and remains in the retracted state. When the mouthwash outlet structure 1 is pressed, the switching shaft 22 moves backward in the opposite direction of the water flow. At this time, the switching shaft 22 is in the first position, and the side outlet 25 of the first water outlet cavity 23 and the inlet 3 of the water outlet component 3 are connected. 1 Corresponding to; the first blocking section 27 moves backward against the direction of water flow and is misaligned with the side water flow channel 29, and under the action of the sealing ring 20, it forms a seal with the cavity wall 51 at this position of the shower body 5, thereby closing the flow of the side water flow channel 29. The water flows in from the inlet end 4, flows to the first outlet cavity 23 of the switching shaft 22, and flows into the inlet 31 of the water outlet assembly 3 from the side outlet 25, thereby realizing the water supply of the water outlet assembly 3, thereby realizing the output of shower water or aerated water.

[0058] like Figure 5 When the mouthwash outlet structure 1 is pressed, pressing the front of the end cap 15 causes the hook 6 to extend outward and hook onto the wall of the guide groove 7, keeping the mouthwash outlet structure 1 extended outward from the cavity wall 51 of the shower head body 5. The outlet 16 of the end cap 15 remains in the extended state and is in a water-dispensing state. When the mouthwash outlet structure 1 is pressed, the switching shaft 22 moves forward synchronously along the water flow direction. At this time, the switching shaft 22 is in the second position, and the side outlet 25 of the first water outlet chamber 23 is misaligned with the inlet 31 of the water outlet assembly 3. The inlet 31 of the water outlet assembly 3 is... The second blocking section 28 is blocked; the first blocking section 27 moves forward along the water flow direction to be opposite to the side water flow channel 29, thereby opening the flow of the side water flow channel 29. The water flows in from the inlet end 4, flows to the first outlet chamber 23 of the switching shaft 22, and flows into the side water flow channel 29 through the side outlet 25. It then flows through the side water flow channel 29 to the side inlet 26 of the second outlet chamber 24, thus supplying water to the second outlet chamber 24. The water flows from the second outlet chamber 24 to the mouthwash outlet structure 1, and is discharged from the outlet 16 of the mouthwash outlet structure 1, thus activating the mouthwash function.

[0059] The beneficial effects of this embodiment are as follows: 1. By obliquely placing the filter device within the mouthwash outlet body, the water outlet direction is changed, allowing water to flow from the upper side of the end cap. This preserves the operating space on the front of the end cap, which can be used to set up a switching button. By misaligning the button operation with the water outlet, manual pressing of the outlet avoids water contamination. 2. By setting up a pressing switching mechanism that works in conjunction with the mouthwash outlet body, the switching movement path of the mouthwash outlet body and the mouthwash outlet structure is axial. This means that switching between different water paths can be achieved simply by pressing the mouthwash outlet body, resulting in a simple and compact operation. 3. By linking the mouthwash outlet body with the pressing switching mechanism for water path switching, the water path switching of the mouthwash outlet structure is completed simultaneously with the activation of the mouthwash outlet body. Operationally, the water path switching status can be determined by checking whether the mouthwash outlet structure is activated, making the showerhead's water output function readily apparent.

[0060] Third embodiment, reference Figure 9 .

[0061] This embodiment provides a pull-out shower head. The shower head body 5 includes a water inlet 4, a water outlet component 3, a mouthwash outlet structure 1, and a water path switching device 2. The water outlet component 3 and the mouthwash outlet structure 1 are independent of each other and are arranged axially within the shower head body 5. The water outlet component 3 can employ a flip-type aerator to achieve two or more types of water spray. The water path switching device 2 is used to switch the water path between the mouthwash outlet structure 1 and the water outlet component 3.

[0062] The water outlet component 3 and the mouthwash outlet structure 1 are arranged vertically within the shower head body 5. A main water passage 52 is connected to the water inlet 4 within the shower head body, and two branch water passages 53 are connected to the main water passage 52. These two branch water passages 53 are respectively connected to the water outlet component 3 and the mouthwash outlet structure 1. A water path switching device 2 is installed at the watershed of the main water passage 52. The water path switching device 2 includes a press-to-switch mechanism 21 for switching the water path between the mouthwash outlet structure 1 and the water outlet component 3. The switching button of the press-to-switch mechanism 21 is located on the shower head body 5, and the switching button is independently arranged from the water outlet component 3 and the mouthwash outlet structure 1.

[0063] The water path switching device 2 includes a pressing switching mechanism 21 and a switching shaft 22 connected to the pressing switching mechanism 21. The pressing switching mechanism 21 is a central bolt structure commonly used for water path switching of pull-out heads. As the pressing end 211 of the pressing switching mechanism 21 is pressed, the switching shaft 22 can automatically extend and retract during the pressing and releasing actions. It will not be described in detail here.

[0064] Pressing the switching button on the switching mechanism 21 allows the switching shaft 22 to move vertically up and down along the axis. This switching shaft 22 moves longitudinally and has a first position and a second position in the direction of movement. In the first position, the switching shaft 22 is switched to correspond with the water outlet component 3, connecting the water distribution path of the water outlet component 3. At this time, water is discharged from the water outlet component 3, but not from the mouthwash outlet structure 1. In the second position, the switching shaft 22 is switched to correspond with the mouthwash outlet structure 1, connecting the water distribution path of the mouthwash outlet structure 1 (e.g., ...). Figure 9 At this time, water is dispensed from mouthwash outlet structure 1, but not from water outlet component 3.

[0065] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
