Technical Field

[0001] The present invention relates to a personal care product, and particularly to a dental irrigator. Background Art

[0002] With the improvement of people's requirements for quality life, dental irrigators have increasingly become a common oral care tool. Along with the improvement of the cleaning power of dental irrigators, the water pressure of the water column ejected is also getting stronger. In the case of the increasing water pressure of the dental irrigator, due to the limitations of the design of the dental irrigator itself, if the user cannot quickly align the cleaning position at startup and clean the oral cavity in the correct way, the oral cavity cannot withstand the instant strong water pressure of the dental irrigator, which is likely to cause the user's gum bleeding. Therefore, it poses a test to the design of the working mode of the multifunctional dental irrigator. How to improve the experience and cleaning comfort of the dental irrigator has become a technical problem to be solved urgently. Summary of the Invention

[0012] 24) The frequency of the water flosser is gradually reduced to K2. <K1<F0。

[0013] In a preferred embodiment: F1 is 1 / N of F3, N is the number of times the water flosser increases from the initial frequency to the target frequency, and F2 is 2 / N of F3.

[0014] In a preferred embodiment: K1 is 1 / N of F0, N is the number of times the water flosser increases from the initial frequency to the target frequency, and K2 is 2 / N of F0.

[0015] In a preferred embodiment: step 3 is also included, and step 3 is operated when the water flosser operates at the target frequency, and includes the following sub-steps:

[0016] 31) The water flosser delivers water at the target frequency F3;

[0017] 32) The frequency of the oral irrigator cycles N times in the pattern of first decreasing, then increasing, then decreasing, then increasing, and each time the frequency decreases, it is closer to F0 than the previous time, and finally reaches F0; each time the frequency decreases, it is further away from F3 than the previous time.

[0018] The present invention also provides a method for regulating the water pressure of a water flosser. The method operates when the water flosser operates at a target frequency and comprises the following steps:

[0019] 1) The water flosser discharges water at the target frequency F3;

[0020] 2) The frequency of the oral irrigator is cycled N times in the pattern of first decreasing, then increasing, then decreasing, then increasing, and finally reaching F0.

[0021] In a preferred embodiment: each time the frequency of the water flosser is reduced, the frequency is closer to F0 than the previous time, and each time the frequency is reduced, the frequency is further away from F3 than the previous time.

[0022] In a preferred embodiment: Step 2 includes the following sub-steps:

[0023] 21) The frequency of the oral irrigator is gradually reduced from F3 to K2, wherein K2<F0, F0 is the initial frequency of the oral irrigator, and F3 is the target frequency of the current gear of the oral irrigator;

[0031] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0032] 1. The present invention provides a method for regulating the water pressure of a water flosser. When the water flosser is started, the working frequency gradually increases to the target frequency in a pattern of first increasing, then decreasing, then increasing, and then decreasing. And each time the frequency decreases, it decreases to a level lower than the initial frequency, so that the water pressure in the oral cavity is sometimes high and sometimes low. The stimulation to the user's oral cavity is reduced. Compared with the method of linearly increasing water pressure, this method is a buffer and relaxation for the oral cavity when the water pressure decreases, and the oral cavity will not be always under the action of gradually increasing water pressure.

[0033] 2. The present invention provides a method for regulating the water pressure of a water flosser. When the water flosser works at a target frequency, the water pressure decreases as the working time increases. This is because a relatively large water pressure is required when cleaning. As the cleaning time increases, the working frequency of the motor gradually decreases. This frequency modulation method allows the pulsed water output by the water flosser to reduce noise and protect the motor according to the frequency change when the working frequency is working. During use, the stinging sensation caused to the teeth during cleaning can be reduced to enhance the user's experience. In addition, the frequency drop is not linear, but first drops rapidly to below the initial frequency, and then rises to above the initial frequency, and this cycle is repeated N times. The advantage of this method is that during the process of flushing teeth, if the user finds that a certain position needs additional cleaning, the water pressure will still increase to facilitate the user to supplement the cleaning. In the linear reduction scheme, when the user finds that a certain position needs additional cleaning, it is difficult to obtain the ideal water pressure. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Example 1

[0041] refer to Figure 1 and Figure 2 The present invention provides a method for regulating the water pressure of a water flosser, which operates when the water flosser is started and includes the following steps:

[0042] 1) When the water flosser is started, water is discharged at the initial frequency F0;

[0043] 2) The frequency of the oral irrigator cycles N times in the pattern of first increasing, then decreasing, then increasing, then decreasing, and each time the frequency increases, it is closer to F3 than the previous time, and finally reaches F3; each time the frequency decreases, it is further away from F0 than the previous time.

[0044] Specifically, in this embodiment, N=3, so step 2 includes the following sub-steps:

[0045] 21) The frequency of the oral irrigator gradually increases to F1, where F1 < F3, and F3 is the target frequency of the current gear of the irrigator.

[0046] 22) The frequency of the oral irrigator gradually decreases to K1, where K1 < F0.

[0047] 23) The frequency of the oral irrigator gradually increases to F2, where F1 < F2 < F3.

[0048] 24) The frequency of the oral irrigator gradually decreases to K2, where K2 < K1 < F0.

[0049] 25) The frequency of the oral irrigator gradually increases to F3.

[0050] It should be noted that the number of times of N can be modified according to actual needs and is not limited to 3.

[0051] In this embodiment, F1 is 1 / N of F3, N is the number of times the oral irrigator increases from the initial frequency to the target frequency, and F2 is 2 / N of F3. K1 is 1 / N of F0, N is the number of times the oral irrigator increases from the initial frequency to the target frequency, and K2 is 2 / N of F0.

[0052] For the above method for adjusting the water outlet water pressure of the oral irrigator, when the oral irrigator is started, the working frequency gradually increases to the target frequency in a mode of first increasing, then decreasing, then increasing again, and then decreasing again. And each time the frequency drops, it drops to a value lower than the initial frequency, so that the water pressure in the oral cavity is sometimes large and sometimes small. The irritation to the user's oral cavity is reduced. Compared with the way of linearly increasing the water pressure, this way provides a buffer and relaxation to the oral cavity when the water pressure decreases, and does not keep the oral cavity under the action of gradually increasing water pressure all the time.

[0053] The above adjustment method is applicable when the oral irrigator is just started. This embodiment also provides a method for adjusting the water outlet water pressure of the oral irrigator. This adjustment method works when the oral irrigator works at the target frequency and includes the following steps:

[0054] 1) The oral irrigator discharges water at the target frequency F3.

[0055] 2) The frequency of the oral irrigator cycles N times in a mode of first decreasing, then increasing, then decreasing again, and then increasing again, and each time the frequency after decreasing is closer to F0 than the previous time and finally reaches F0; each time the frequency after decreasing is farther from F3 than the previous time.

[0056] Specifically, in this embodiment, N = 3, so step 2 includes the following sub-steps:

[0057] 21) The frequency of the oral irrigator is gradually reduced from F3 to K2, wherein K2<F0, F0 is the initial frequency of the oral irrigator, and F3 is the target frequency of the current gear of the oral irrigator;

[0058] 22) The frequency of the water flosser is gradually increased to F2. <F3;

[0059] 23) The frequency of the water flosser is gradually reduced to K1, K2 <K1<F0;

[0060] 24) The frequency of the water flosser is gradually increased to F1, wherein F2>F1>F0;

[0061] 25) Gradually reduce the frequency of the oral irrigator to F0.

[0062] In this embodiment, K2 is 2 / N of F0, N is the number of times the water flosser drops from the target frequency to the initial frequency, and K1 is 1 / N of F0. F1 is 1 / N of F3, N is the number of times the water flosser drops from the target frequency to the initial frequency, and F2 is 2 / N of F3.

[0063] In the above-mentioned method for regulating the water pressure of the water flosser, when the water flosser works at the target frequency, the water pressure decreases as the working time increases. Because when just cleaning, a relatively large water pressure is required. As the cleaning time increases, the working frequency of the motor gradually decreases. This frequency modulation method allows the pulse water output by the working frequency of the water flosser to achieve the effect of reducing noise and protecting the motor according to the frequency change during operation. During use, it can reduce the tingling sensation caused to the teeth during cleaning to enhance the user's experience. In addition, the frequency drop is not linear, but first drops quickly to below the initial frequency, and then rises to above the initial frequency, and this cycle is repeated N times. The advantage of this method is that during the user's tooth flushing process, if a certain position is found to need additional cleaning, the water pressure will still increase to facilitate the user's additional cleaning. In the linear reduction solution, when the user finds that a certain position needs additional cleaning, it is difficult to obtain the ideal water pressure.

[0064] The present embodiment also provides a water flosser, which uses the above-mentioned water outlet pressure regulating method. The present embodiment also provides a water flosser, which includes a water flosser body and a control chip disposed in the body, wherein the control chip stores a program corresponding to the above-mentioned water outlet pressure regulating method.

[0065] Example 2

[0066] The difference between this embodiment and the first embodiment is that, in the first embodiment, when the water flosser is started, the water pressure adjustment mode is first increase-then decrease-then increase-then decrease. In the present embodiment, the mode is changed to first increase-then decrease-then increase-then decrease. The rest of the parts are the same as the first embodiment and will not be repeated.

[0067] The above is only a preferred specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the protection scope of the present invention.
