[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0032] like Figures 1 to 7 As shown, this embodiment of a mouthwash nozzle replaceable pull-out head includes a pull-out head body 1 and a mouthwash nozzle 2.

[0033] The pull-out head body 1 is provided with a water nozzle mounting hole 11; the mouthwash nozzle 2 is detachably and rotatably mounted in the water nozzle mounting hole 11; the outer end face of the mouthwash nozzle 2 is provided with a mouthwash outlet 21, which is connected to the water passage inside the pull-out head body 1; the outer end of the mouthwash nozzle 2 is also recessed with two spaced-apart disassembly holes 22.

[0034] Therefore, the mouthwash nozzle 2 in this embodiment has no protruding structure, which ensures a neat appearance. Moreover, by inserting a tool into the two disassembly holes 22, the mouthwash nozzle 2 can be easily unscrewed from the water nozzle mounting hole 11, and the mouthwash nozzle 2 can be easily removed from the pull-out head body 1 for cleaning and decontamination of the mouthwash nozzle 2 and the water nozzle mounting hole 11. While providing the mouthwash function of the pull-out head, it can ensure smooth water flow and hygiene.

[0035] In this embodiment, the mouthwash nozzle 2 can be completely embedded in the nozzle mounting hole 11. This ensures that the pull-out head has a flat overall shape, making it easy to clean and maintain. The two disassembly holes 22 can be symmetrically arranged on both sides of the mouthwash outlet 21.

[0036] See Figure 3 and Figure 4 In this embodiment, the mouthwash nozzle 2 has several circumferentially spaced locking blocks 23 on its peripheral wall; the nozzle mounting hole 11 has at least two circumferentially spaced slots 111; the slots 111 allow the locking blocks 23 to rotate and engage for fixation. Through the cooperation of the locking blocks 23 and the slots 111, the mouthwash nozzle 2 can be quickly rotated and installed in the nozzle mounting hole 11. Alternatively, the mouthwash nozzle 2 can also be rotated and installed in the nozzle mounting hole 11 via threads, but this requires multiple rotations during installation and disassembly.

[0037] Specifically, the pull-out head body 1 includes a housing 12 and an inner core 13 installed in the housing 12; the water tap mounting hole 11 includes an inner core hole 131 provided in the inner core 13 and a clearance hole 121 provided on the housing 12; the slot 111 is provided in the inner core hole 131.

[0038] The inner core 13 may include a front water channel 132, a rear water channel 133 and an upper water channel 134. The front water channel 132 and the rear water channel 133 are assembled and connected front to back. The upper water channel 134 is located at the top front side of the front water channel 132. The inner core hole 131 may be located at the upper water channel 134 to spray mouthwash upward for convenient use.

[0039] The outer end face of the inner core hole 131 can protrude outward with two spaced protrusions 1311, and a clearance area 1312 is formed between the two protrusions 1311; the slot 111 is formed in the protrusion 1311, the slot 111 is radially inward connected to the inner core hole 131, and one end of the two slots 111 in the same circumferential direction has a slot opening 1111 connected to the clearance area 1312.

[0040] During installation, when the mouthwash nozzle 2 is inserted into the inner core hole 131 through the clearance hole 121 of the housing 12, the locking block 23 of the mouthwash nozzle 2 can be placed in the clearance area 1312 and move circumferentially between the clearance area 1312 and the slot 111. In this embodiment, if the mouthwash nozzle 2 is rotated counterclockwise, the locking block 23 can enter the slot 111 to realize the installation of the mouthwash nozzle 2 and the water nozzle mounting hole 11. If the mouthwash nozzle 2 is rotated clockwise, the locking block 23 can be removed from the slot 111 to realize the disassembly of the mouthwash nozzle 2 and the water nozzle mounting hole 11.

[0041] In this embodiment, the other end of the two slots 111 in the same circumferential direction is closed, so that the mouthwash nozzle 2 rotates counterclockwise. After the locking block 23 enters the slot 111, it can abut against the closed end to prevent excessive rotation and ensure the locking stability.

[0042] See also Figure 6 The slot 111 can be a straight slot, and the width of the slot opening 1111 is greater than the width of the slot 111 sealing end. This allows the card block 23 to easily enter the slot 111 from the slot opening 1111, preventing jamming.

[0043] For example Figure 5 As shown, the mouthwash nozzle 2 can be divided into inner and outer sections. The outer diameter of the outer section 24 of the mouthwash nozzle 2 is adapted to the diameter of the relief hole 121, while the outer diameter of the inner section 25 of the mouthwash nozzle 2 can be smaller than the outer diameter of the outer section 24. Furthermore, the locking block 23 can be disposed in the inner section 25, and the protrusion of the locking block 23 does not exceed the peripheral wall of the outer section 24. Therefore, after the mouthwash nozzle 2 is fully embedded in the water tap mounting hole 11, the mouthwash nozzle 2 tightly seals the water tap mounting hole 11, reducing gaps. The locking block 23, located in the inner section 25 with a smaller inner diameter, does not affect the insertion of the mouthwash nozzle 2 into the relief hole 121 and its engagement with the locking groove 111.

[0044] Meanwhile, in this embodiment, the bottom surface 112 of the faucet mounting hole 11 can be inclined relative to the inner end surface 26 of the mouthwash nozzle 2 to form a triangular gap groove 14. The wider part of the triangular gap groove 14 is connected to the internal water passage of the pull-out head body 1, thereby improving water output efficiency and increasing water volume.

[0045] For further details, please refer to [link / reference]. Figure 6The bottom surface 112 of the water tap mounting hole 11 may also have several circumferentially arranged top blocks 1121 protruding from its periphery. Each top block 1121 extends outward until it abuts against the outer periphery of the inner end face 26 of the mouthwash nozzle 2. Therefore, since the height of the top block 1121 protruding near the wider part of the triangular gap groove 14 is greater than the height on the other side, it can assist in abutting against the inner end face 26 of the mouthwash nozzle 2 during installation, so that the inner end face 26 always remains inclined to the bottom surface 112 of the water tap mounting hole 11, and the locking block 23 can be accurately aligned and locked into the locking groove 111.

[0046] A pusher post 1122 may protrude from the middle of the bottom surface 112 of the faucet mounting hole 11, and the pusher post 1122 abuts against the middle of the inner end face 26 of the mouthwash nozzle 2. This also serves to provide a pusher and positioning effect.

[0047] like Figure 3 As shown, the mouthwash nozzle 2 in this embodiment may include a nozzle base 27, a flow restrictor 28, and a filter screen 29. The nozzle base 27 has a recessed blind hole 271 at its inner end and a mouthwash outlet 21 communicating with the blind hole 271 at its outer end. Both the flow restrictor 28 and the filter screen 29 are accommodated and installed within the blind hole 271, with the filter screen 29 located between the flow restrictor 28 and the mouthwash outlet 21. The flow restrictor 28 increases water pressure, and the filter screen 29 performs filtration, ensuring hygiene and safety.

[0048] The product of this embodiment may also be equipped with a disassembly handle 3 when it leaves the factory, so that the user can disassemble the mouthwash nozzle 2 by himself.

[0049] Specifically, the disassembly handle 3 may include a handle base 31, locking points 32, and a handle 33. Two spaced locking points 32 protrude from one side of the handle base 31, each locking point 32 aligning with the two disassembly holes 22 of the mouthwash nozzle 2. The handle 33 protrudes from the other side of the handle base 31. In use, the handle 33 is pinched, and the two locking points 32 are inserted into the two disassembly holes 22. Rotating counterclockwise disengages the mouthwash nozzle 2 locking block 23 from the slot 111 into the clearance area 1312, allowing for easy removal or emptying of the mouthwash nozzle 2 for cleaning or replacement.

[0050] In this embodiment, the inner core 13 also includes a switching valve stem 135, a switching knob 136, a spring 137, and a water outlet panel assembly 138. The water outlet panel assembly 138 is detachably screwed to the end of the front water channel 132 at the downward bend. The switching valve stem 135 is reciprocally mounted between the front water channel 132 and the rear water channel 133. The spring 137 abuts against one end of the switching valve stem 136. The switching knob 136 is movable and exposed in the housing 12, and is used to drive the switching valve stem 135 to reciprocate.

[0051] The rear water channel 133 has an inlet water passage 1331, and the front water channel 132 has a drain water passage 1321 and an upper water passage 1322. The outlet of the upper water passage 1322 is connected to the mouthwash outlet 21, and the outlet of the drain water passage 1321 is connected to the water outlet panel assembly 138. The switching valve rod 135 is used to switch the inlet water passage 1331 to selectively connect the drain water passage 1321 and the upper water passage 1322. Thus, by tossing the switching knob 136, which moves the switching valve rod 135, water can be dispensed from the water outlet panel assembly 138 of the pull-out head or from the mouthwash nozzle 2. The water outlet panel assembly 138 is detachably threaded, allowing for easy removal and cleaning.
