Technical Field

[0001] The invention relates to the field of oral irrigators, and in particular to a spray rod of an oral irrigator capable of adjusting water pressure. Background Art

[0002] Existing water irrigators all adjust the water pressure of the water irrigator by replacing nozzles with different apertures. A single nozzle cannot adjust the water pressure of the water irrigator. In the actual use of the water irrigator, the user needs to use a variety of water pressures to complete oral cleaning or gum massage. A single nozzle cannot adjust the water pressure of the water irrigator. The user needs to replace nozzles with different apertures to meet the use requirements. However, nozzles with different apertures have different water pressures. The user cannot always sense the water pressure and sometimes needs to replace multiple nozzles to meet the use requirements, which makes the entire use process very cumbersome.

[0020] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0021] Please refer to Figures 1 to 5 The present invention proposes a water flosser spray rod capable of adjusting water pressure, the water flosser spray rod capable of adjusting water pressure comprising: a nozzle 10, a pressure regulating part 20 and a rod body 30; the nozzle 10 is provided with a water outlet 11, the top of the pressure regulating part 20 is provided with an opening 21, the pressure regulating part 20 is fixedly connected to the rod body 30 and communicated with the rod body 30, the nozzle 10 is threadedly connected to the rod body 30 and the pressure regulating part 20 respectively, the pressure regulating part 20 is accommodated in the nozzle 10 and partially extends into the water outlet 11, the opening 21 is communicated with the water outlet 11, the inner wall of the water outlet 11 abuts against the pressure regulating part 20, and the size of the opening 21 can be adjusted by screwing the nozzle 10.

[0022] In this embodiment, the diameter of the water outlet hole 11 decreases from the inside to the outside. When the nozzle 10 is screwed in a clockwise direction, the nozzle 10 moves toward the direction close to the rod body 30, and the pressure regulating part 20 is further accommodated in the water outlet hole 11. The inner wall of the water outlet hole 11 abuts against the pressure regulating part 20, and the nozzle 10 squeezes the pressure regulating part 20 to reduce the opening 21; when the nozzle 10 is screwed in a counterclockwise direction, the nozzle 10 moves toward the direction away from the rod body 30, the length of the pressure regulating part 20 accommodated in the water outlet hole 11 is reduced, and the pressure regulating part 20 stretches to increase the opening 21.

[0023] In this embodiment, the pressure regulating part 20 is connected to the rod body 30, and the opening 21 is connected to the water outlet 11 so that the rod body 30 is connected to the water outlet 11. When the water irrigator spray rod capable of adjusting water pressure is installed on the external water irrigator host, the external water irrigator host transmits water into the rod body 30, and the water enters the pressure regulating part 20 through the rod body 30, and then enters the water outlet 11 through the opening 21, and finally is ejected from the nozzle 10 through the water outlet 11. The size of the opening 21 can be adjusted by screwing the nozzle 10, thereby adjusting the water spraying pressure of the water outlet 11. There is no need to replace the nozzle 10 during use. The water spraying pressure of the water outlet 11 can be adjusted by screwing the nozzle 10. The operation is very simple.

[0024] Furthermore, the pressure regulating portion 20 is provided with a plurality of regulating flaps 22 , and the regulating flaps 22 are partially received in the water outlet hole 11 and abut against the inner wall of the water outlet hole 11 , and the plurality of regulating flaps 22 form the opening 21 .

[0025] In this embodiment, the number of the regulating flaps 22 is three. The regulating flaps 22 are made of soft material and can be squeezed by the nozzle 10 to reduce the opening 21 .

[0026] Furthermore, there is a gap between the two regulating flaps 22 .

[0027] In this embodiment, the pressure regulating part 20 is connected to the nozzle 10 through the gap between the two regulating flaps 22, and water enters the nozzle 10 through the gap between the two regulating flaps 22. After the water fills the inside of the nozzle 10, the water enters the water outlet 11 from the gap between the two regulating flaps 22 and the opening 21.

[0028] In this embodiment, when the nozzle 10 is screwed in a clockwise direction, the nozzle 10 moves toward the direction approaching the rod body 30, and the regulating flap 22 is further accommodated in the water outlet hole 11. The inner wall of the water outlet hole 11 abuts against the regulating flap 22, and the nozzle 10 squeezes the regulating flap 22 to reduce the opening 21, and the nozzle 10 squeezes the regulating flap 22 to reduce the gap between the two regulating flaps 22; when the nozzle 10 is screwed in a counterclockwise direction, the nozzle 10 moves toward the direction away from the rod body 30, the length of the regulating flap 22 accommodated in the water outlet hole 11 is reduced, the regulating flap 22 stretches to enlarge the opening 21, and the gap between the two regulating flaps 22 is enlarged.

[0029] Furthermore, the pressure regulating part 20 further includes a base 23 , the regulating flap 22 is fixedly mounted on the base 23 , and the base 23 is threadedly connected to the nozzle 10 .

[0030] In this embodiment, the base 23 is received in the nozzle 10 and is threadedly connected to the nozzle 10 .

[0031] Furthermore, a positioning block 24 is provided at one end of the base 23 away from the regulating flap 22 , a mounting seat 31 is provided on the rod body 30 , a positioning groove 33 is provided on the mounting seat 31 , and the positioning block 24 is fixedly accommodated in the positioning groove 33 .

[0032] In this embodiment, the mounting seat 31 is fixedly mounted on the rod body 30 , and the positioning block 24 is fixedly received in the positioning groove 33 . The positioning block 24 limits the rotation of the base 23 , and the base 23 will not rotate even if the nozzle 10 is screwed.

[0033] Furthermore, the mounting seat 31 is received in the nozzle 10 and is threadedly connected to the nozzle 10 .

[0034] In this embodiment, the nozzle 10 is threadedly connected to the mounting seat 31 and the base 23 respectively.

[0035] Furthermore, the water pressure adjustable oral irrigator spray rod also includes a waterproof ring 40 , a mounting groove 32 is provided on the rod body 30 , and the waterproof ring 40 is partially accommodated in the mounting groove 32 , and the waterproof ring 40 abuts against the nozzle 10 .

[0036] In this embodiment, the waterproof ring 40 is located below the mounting seat 31, and the waterproof ring 40 is accommodated in the nozzle 10. The waterproof ring 40 eliminates the gap between the nozzle 10 and the rod body 30, so that the water in the nozzle 10 cannot flow out of the nozzle 10 through the gap between the nozzle 10 and the rod body 30.

[0037] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
