Description

Technical Field

[0001] This utility model relates to the field of oral irrigator technology, and in particular to an ultrasonic oral irrigator device. Background Technology

[0002] An ultrasonic water flosser is a dental care tool that uses high-frequency vibrations to clean teeth. Compared to ordinary water flossers, it generates microbubbles through ultrasonic vibrations and uses air pressure to propel the cleaning solution deep into hard-to-reach areas such as between teeth, gum lines, and orthodontic appliances, effectively removing plaque, tartar, and stains. Moreover, the cleaning process is gentler and less irritating to teeth and gums, making it especially suitable for sensitive individuals.

[0003] In current ultrasonic water flossers, the ultrasonic transducer used to generate high-frequency vibrations is generally located inside the water tank or at the water inlet of the nozzle. If it is located inside the water tank, the ultrasonic transducer handles more water per unit time, resulting in fewer microbubbles per unit volume of water, leading to poor cleaning of hard-to-reach areas inside the teeth. If it is located at the water inlet of the nozzle, it increases the distance the water travels from the pump outlet to the nozzle outlet, resulting in a longer water flow path, which affects the water flow impact force and thus leads to poor rinsing effect. Utility Model Content

[0004] The purpose of this invention is to provide an ultrasonic dental flushing device to solve the problems of low microbubble generation and weak water flow impact.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An ultrasonic dental flushing device includes a housing, a dental flushing nozzle, and a water pump. The housing has a accommodating cavity. The dental flushing nozzle is located at the top of the housing. The water pump is located inside the accommodating cavity and communicates with the dental flushing nozzle. A water tank is located outside the housing. An ultrasonic transducer is located inside the accommodating cavity and is arranged horizontally alongside the water pump. The ultrasonic transducer has a water passage extending through it. One end of the water passage is connected to the water tank, and the other end of the water passage is connected to the water inlet of the water pump.

[0007] In one embodiment, the ultrasonic transducer is connected to the water pump via a flexible hose; and / or, the ultrasonic transducer is connected to the water tank via a flexible hose.

[0008] In one embodiment, the water tank is disposed outside the outer casing and is detachably connected to the water tank.

[0009] In one embodiment, the water tank includes a water tank body and a water pumping pipe. The water tank body is fixedly disposed at the bottom of the outer shell, and the water pumping pipe is disposed inside the water tank body and communicates with the ultrasonic transducer.

[0010] In one embodiment, the water tank further includes a filter nozzle disposed at the end of the water pump pipe away from the outer casing.

[0011] In one embodiment, a one-way valve is provided between the ultrasonic transducer and the water pump, and the one-way valve only allows water to flow from the ultrasonic transducer toward the water pump.

[0012] In one embodiment, the ultrasonic dental flushing device further includes a bracket, which includes a first bracket and a second bracket. The first bracket and the second bracket enclose an installation space, and the water pump is disposed within the installation space.

[0013] In one embodiment, the ultrasonic transducer includes a guide rod, a guide rod seat, an ultrasonic ring, and a conductive copper sheet. A first guide hole is provided through the guide rod seat. The guide rod, the ultrasonic ring, and the conductive copper sheet are all sleeved on the guide rod seat. A second guide hole is provided through the guide rod. The second guide hole and the first guide hole together form the water passage.

[0014] In one embodiment, the rinsing nozzle includes a spray bar and a nozzle. A water spraying channel is provided through the spray bar. The nozzle is detachably mounted on the spray bar and communicates with the water spraying channel. The water spraying channel is connected to the outlet of the water pump.

[0015] In one embodiment, the ultrasonic transducer is a piezoelectric ceramic ultrasonic transducer.

[0016] The beneficial effects of this invention are as follows: The ultrasonic dental irrigator of this invention places the ultrasonic transducer between the water tank and the water pump. Compared to placing it inside the water tank or at the water inlet of the dental irrigator nozzle, this provides a higher number of microbubbles and makes the water jet from the nozzle more impactful, resulting in better cleaning of teeth. Furthermore, compared to placing it at the water inlet of the dental irrigator nozzle or inside the water tank, the ultrasonic transducer replaces part of the water pipes that originally connected the water tank and the water pump, saving on manufacturing costs. Moreover, the horizontal parallel arrangement of the ultrasonic transducer and water pump, compared to placing them below or above the water pump, better utilizes the space of the accommodating cavity, resulting in a more compact layout and reducing the overall size of the ultrasonic dental irrigator.

[0027] refer to Figures 1-4 As shown in the figure, an ultrasonic dental flushing device is proposed in the embodiment of this utility model, including a shell 1, a dental flushing nozzle 2, a water pump 3, a water tank 4, and an ultrasonic transducer 5. The dental flushing nozzle 2 is disposed on the top of the shell 1, the water tank 4 is fixedly connected to the shell 1, the shell 1 is provided with a receiving cavity, the water pump 3 and the ultrasonic transducer 5 are both disposed in the receiving cavity and are arranged side by side with the ultrasonic transducer 5 and the water pump 3 in the horizontal direction, the ultrasonic transducer 5 is provided with a water passage, the water inlet of the water pump 3 is disposed on one side of the water pump 3 and is connected to the outlet of the water passage, the inlet of the water passage is connected to the water tank 4, and the water outlet of the water pump 3 is disposed on the top of the water pump 3 and is connected to the dental flushing nozzle 2.

[0028] The aforementioned ultrasonic dental irrigator places the ultrasonic transducer 5 between the water tank 4 and the water pump 3. Compared to placing it inside the water tank 4 or at the water inlet of the dental irrigator nozzle 2, this provides a higher number of microbubbles and makes the water jet from the dental irrigator nozzle 2 more impactful, resulting in better cleaning of teeth. Furthermore, compared to placing it at the water inlet of the dental irrigator nozzle 2 or inside the water tank 4, the ultrasonic transducer 5 replaces part of the water pipe originally used to connect the water tank 4 and the water pump 3, saving on the manufacturing cost of the ultrasonic dental irrigator. Moreover, the horizontal parallel arrangement of the ultrasonic transducer 5 and the water pump 3, compared to placing them below or above the water pump 3, allows for better utilization of the cavity space, resulting in a more compact layout and a smaller overall size of the ultrasonic dental irrigator.

[0029] Specifically, refer to Figure 3As shown, the water pump 3 is a piston pump, including a piston rod 32, a pump body 31, an inlet seat 36, an outlet seat, and a drive component 35. Both the inlet and outlet of the water pump 3 are located on the pump body 31. The inlet seat 36 is fixedly mounted on the inlet of the pump body 31 and is sealed to it. The inlet seat 36 is connected to the ultrasonic transducer 5 via a first connecting pipe 6. The first connecting pipe 6 is a flexible hose, designed to buffer the vibrations generated by the ultrasonic transducer 5 and extend the service life of the water pump 3. Similarly, the ultrasonic transducer 5 is connected to the water tank 4 via a second connecting pipe 7, which is also a flexible hose, to prevent vibration of the water tank 4. The water outlet seat is located at the water outlet of the pump body 31 and connected to the flushing nozzle 2. The drive component 35 is preferably a motor. In order to convert the rotational motion of the motor into the linear motion of the piston rod 32 in the pump body 31, the water pump 3 also includes a drive bevel gear 33 and a transmission bevel gear 34. The output shaft of the motor is vertically arranged. The drive bevel gear 33 is fixedly sleeved on the output shaft of the motor. The transmission bevel gear 34 is rotatably arranged on the bracket 8 and meshes with the drive bevel gear 33. The piston rod 32 is eccentrically connected to the transmission bevel gear 34. When the transmission bevel gear 34 rotates under the drive bevel gear 33, the piston rod 32 performs linear reciprocating motion, thereby drawing water from the water tank 4 into the ultrasonic transducer 5 and pressurizing it.

[0030] To prevent water from flowing back from the water pump 3 to the ultrasonic transducer 5, a one-way valve is also provided between the ultrasonic transducer 5 and the water pump 3. The one-way valve is located on the water inlet seat 36 and connected to the ultrasonic transducer 5. The one-way valve only allows water to flow from the ultrasonic transducer 5 to the water pump 3.

[0031] It is understood that the water tank 4 can be located either inside the accommodating cavity or outside the outer casing 1. In one embodiment, the water tank 4 is located outside the outer casing 1 and is positioned at the end of the outer casing 1 away from the oral irrigator nozzle 2, that is, the water tank 4 is located at the bottom of the outer casing 1, so as to avoid affecting the user's grip on the ultrasonic oral irrigator. Furthermore, the bottom surface area of ​​the water tank 4 is larger than the bottom surface area of ​​the outer casing 1, so that the ultrasonic oral irrigator can stand stably on the external support surface, which is not limited to a washbasin surface or a tabletop.

[0032] To facilitate water replenishment to the water tank 4, the water tank 4 is detachably connected to the outer casing 1 using a method not limited to snap-fit. Specifically, the top of the water tank 4 has an insert hole, and the end of the outer casing 1 furthest from the water jet nozzle 2 is inserted into the insert hole and fixedly connected to the water tank 4. More specifically, the water tank 4 includes a water tank body 41 and a water suction pipe 42. The water tank body 41 is fixed to the bottom of the outer casing 1, and the water suction pipe 42 is located inside the water tank 4, with its lower end extending towards the bottom of the water tank 4 to draw as much water as possible from the water tank 4. To prevent the water suction pipe 42 from moving inside the water tank 4 and affecting the water suction effect, the water suction pipe 42 is made of rigid material. To reduce assembly difficulty and facilitate the disassembly of the water tank 4 from the outer casing 1 for water replenishment, a connecting sleeve is provided on the end face of the outer casing 1 facing the water tank 4. The water suction pipe 42 is inserted into the connecting sleeve, and the second connecting pipe 7 is also inserted into the connecting sleeve to achieve connection with the water suction pipe 42.

[0033] In one embodiment, the water tank 4 further includes a filter nozzle 43, which is disposed at the end of the water pumping pipe 42 away from the connecting sleeve, that is, at the end of the water pumping pipe 42 away from the outer casing 1, and is used to filter out impurities in the water entering the water pumping pipe 42 to prevent impurities from clogging the ultrasonic transducer 5 and / or the dental spray nozzle 2.

[0034] The ultrasonic dental cleaning device also includes a control circuit board 9, control buttons, and a battery 10. The control buttons are embedded on one side of the housing 1 and include, but are not limited to, a power switch, a water pump switch for controlling the water pump 3, and a power adjustment button for the ultrasonic transducer 5. The control circuit board 9 is fixed inside the housing 1 by a bracket 8 and is electrically connected to the water pump 3, the ultrasonic transducer 5, and the battery 10. The battery 10 is a rechargeable battery. To facilitate charging the battery 10, the ultrasonic dental cleaning device also includes a charging head electrically connected to the battery 10.

[0035] Specifically, the bracket 8 includes a first bracket 81 and a second bracket 82, wherein the control circuit board 9 is fixed on the first bracket 81, and the second bracket 82 is located on the side of the first bracket 81 facing away from the control circuit board 9. The first bracket 81 and the second bracket 82 enclose a mounting space for mounting the water pump 3. The water pump 3 is disposed within the mounting space to prevent other functional components inside the housing 1 from getting caught between the drive bevel gear 33 and the transmission bevel gear 34, such as wires connected to the control circuit board 9. It is understood that the water inlet seat 36 of the water pump 3 extends out of the mounting space to connect with the ultrasonic transducer 5.

[0036] refer to Figure 2 and Figure 4As shown, the ultrasonic transducer 5 includes a guide rod 51, a guide rod seat 52, ultrasonic rings 53, and conductive copper sheets (not shown in the figure). Both the guide rod seat 52 and the guide rod 51 are made of stainless steel. The guide rod seat 52 is fixed to the water outlet seat and has a first guide hole connecting to the water outlet seat. A first connecting pipe 6 is sleeved on the top of the guide rod seat 52. The guide rod 51 has a slender rod-like structure. One end of the guide rod 51 is sleeved on the lower end of the guide rod seat 52 and threadedly connected to it. The other end of the guide rod 51 is connected to the water pumping pipe 42. A second guide hole is formed through the guide rod 51, connecting to the first guide hole to form a water passage for water flow. Two ultrasonic rings 53 and two conductive copper sheets are alternately sleeved on the guide rod seat 52. The two conductive copper sheets are electrically connected to the control circuit board 9 via wires, with one conductive copper sheet serving as the positive electrode and the other as the negative electrode. The guide rod 51 extends the water flow path within the ultrasonic transducer 5, increases the number of microbubbles in the water, and further improves the teeth cleaning effect of the water flosser.

[0037] Preferably, the ultrasonic transducer 5 is a piezoelectric ceramic ultrasonic transducer, which can emit true ultrasound with a frequency of 40KHz to 100KHz and produce microbubbles effectively.

[0038] refer to Figure 3 As shown, the dental floss nozzle 2 includes a spray bar 21 and a nozzle 22. The nozzle 22 is detachably mounted on the spray bar 21 and communicates with a water spray channel provided inside the spray bar 21. The water spray channel of the spray bar 21 is connected to the outlet of the water pump 3. It is understandable that the nozzle 22 is prone to clogging after long-term use. Therefore, it is designed to be detachable from the spray bar 21, which facilitates the replacement of the nozzle 22 and reduces the replacement cost compared to replacing the entire dental floss nozzle 2.
