[0002] A dental irrigator mainly includes a water tank, a water pipe, a pump and a nozzle. The water tank is used to hold the cleaning liquid and supply it. The two ends of the water pipe are connected to the water tank and the nozzle respectively. The pump is connected to the water pipe and is used to push the cleaning liquid out of the nozzle to rinse the teeth. Generally speaking, there are also various choices for the cleaning liquid. Some cleaning liquids have a disinfection function, but in more cases, clean water is used as the cleaning liquid.

[0003] When using a dental irrigator to rinse teeth, the tolerance of different parts of the oral cavity to external stimuli is different. For example, the tolerance of molars is greater than that of incisors. Therefore, molars can withstand stronger impact pressure, and incisors can withstand less impact pressure. However, in the prior art, the adjustment of the impact pressure is mostly in the form of gears, such as the ability to adjust high-pressure, medium-pressure and low-pressure gears.

[0035] Next, in combination with the attached Figure 1 to the attached Figure 3 and the specific embodiments, the present invention will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0036] As Figures 1 to 3 shown, the present invention provides a dental irrigator with a flexible pressure electro-controlled nozzle. The dental irrigator includes a nozzle 3, a water pipe 4, a water tank and a water pump. The two ends of the water pipe 4 are respectively connected to the nozzle 3 and the water tank, and the water pump is connected to the water pipe 4. The dental irrigator further includes an electro-controlled pipe group 5, and the electro-controlled pipe group 5 includes: a deformation pipe 51, a coil 52, a magnetic induction chip 53 and a protective sleeve 54. The deformation pipe 51 is arranged in the protective sleeve 54. The two ends of the deformation pipe 51 are respectively connected to the water pipe 4 and the nozzle 3. The coil 52 is wound around the deformation pipe 51, and the magnetic induction chip 53 is arranged in the protective sleeve 54 for detecting the magnetic induction intensity of the coil 52. The dental irrigator further includes a control unit, the control unit is electrically connected to the coil 52 for supplying power to the coil 52, the control unit is electrically connected to the magnetic induction chip 53 for receiving the induced electrical signal sent by the magnetic induction chip 53, and the control unit is electrically connected to the water pump and controls the water pump power according to the induced electrical signal. In this embodiment, the control unit supplies power to the coil 52, so that the coil 52 generates a magnetic field, and at the same time, the magnetic induction intensity is sensed by the magnetic induction chip 53. In the electro-controlled pipe group 5, the coil 52 is wound around the deformation pipe 51, and at the same time, the protective sleeve 54 is sleeved outside the deformation pipe 51 and the coil 52, so as to protect the coil 52 and the deformation pipe 51. During use, by pressing the protective sleeve 54, the coil 52 and the deformation pipe 51 are deformed, the cross-sectional area of the coil 52 changes, the magnetic induction intensity changes, the magnetic induction chip 53 senses the change of the magnetic induction intensity and generates an induced electrical signal. After receiving the induced electrical signal, the control unit adjusts the water pump power according to the change of the induced electrical signal. In this embodiment, it is possible to change the cross-sectional area of the coil 52 by pressing the protective sleeve 54 with the hand, and accurately adjust the water pump power by changing the pressure applied to the protective sleeve 54 by the handle 2, and the water pump power can be adjusted at any time with the change of the flushing part, and the adjustment of the water pump power is more timely.

[0037] The protective sleeve 54 can protect the coil 52, prevent the coil 52 from being damaged and causing power regulation failure, and improve the service life of the electro-controlled pipe group 5.

[0038] For the deformation pipe 51, specifically, the deformation pipe 51 can be an elastic hose that can return to its initial shape. The elastic hose returns to its initial shape by virtue of its own elasticity. More specifically, the elastic hose returning to its initial shape means that it can return to its radial deformation when it undergoes radial deformation under radial pressure. For the deformation pipe 51, it can also be a flexible hose without the ability to return, and the flexible hose returns to its initial shape by virtue of the impact pressure of water. In this embodiment, an elastic hose is preferably used.

[0039] In addition, for the magnetic induction chip 53, its specific position can be set on one side of the coil 52 along the axial direction. In this way, the magnetic induction chip 53 can avoid the deformed coil 52, prevent the wires connecting the control unit and the magnetic induction chip 53 from being bent multiple times, avoid wire failures, and improve the stability of the electrical signal connection between the magnetic induction chip 53 and the electronic control power supply.

[0040] In addition, for the magnetic induction chip 53, its specific position can be set inside the coil 52. In this way, the magnetic induction chip 53 can more accurately sense the change in magnetic induction intensity, improving the accuracy of water pump control.

The water pump is also arranged inside the base 1. The nozzle 3 is connected to one end of the handle 2, and the water pipe 4 is connected to the other end of the handle 2.
