Description

Technical Field

[0001] This invention relates to an electric spray toothbrush with a replaceable atomizing head. Background Technology

[0002] An electric toothbrush, invented by Philippe-Guy Woog, uses a rapidly rotating or vibrating motor to create high-frequency vibrations in the brush head, instantly breaking down toothpaste into fine foam. Simultaneously, the bristle vibrations promote blood circulation in the mouth and massage the gum tissue. It utilizes the cavitation effect of energy in the periodontal tissues to remove bacteria and debris, which are then delivered to the teeth and gums through the bristles. However, electric toothbrushes cannot reach the hard-to-reach areas of the mouth.

[0003] With the development of electric toothbrushes, electric spray toothbrushes later emerged. These spray toothbrushes can apply liquid toothpaste to teeth while brushing, allowing it to quickly penetrate into hard-to-reach areas like between teeth for thorough disinfection and preventing toothpaste from peeling off. While they can deeply clean gums and reduce oral bacteria when used with various medications, their whitening and cleaning abilities are still insufficient compared to traditional toothpaste.

[0004] Meanwhile, with the design of aero-spray toothpaste, as the number of uses increases, the foamed toothpaste will accumulate in the air outlet, calcify, block the airflow, and eventually become unusable. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention proposes an electric spray toothbrush with a replaceable atomizing head. This toothbrush, based on the traditional combination of toothpaste and an electric toothbrush, adds an atomizing head with an ultrasonic atomizing plate. While using toothpaste to clean the tooth surface, the ultrasonic atomizing plate in the atomizing head atomizes the toothpaste in the toothpaste chamber, simultaneously cleaning the gums and hard-to-reach areas of the mouth.

[0006] The technical solution of this invention to solve the above problems is: an electric spray toothbrush with a replaceable atomizing head, which is special in that:

[0007] Includes the toothbrush body, functional circuitry, replaceable brush head, and replaceable atomizing nozzle;

[0008] The functional circuit is located inside the toothbrush body. The replaceable brush head and replaceable atomizing nozzle are detachably mounted on the toothbrush body. The toothbrush body contains a motor, and the functional circuit controls the motor to generate mechanical waves to drive the brush head to vibrate. The replaceable atomizing nozzle contains an atomizing nozzle and a medicine chamber. The atomizing nozzle contains an ultrasonic atomizing plate. The functional circuit controls the atomizing nozzle to atomize and spray the medicine from the medicine chamber, achieving deep cleaning of the gums and oral cavity.

[0009] Furthermore, the toothbrush body contains a battery to power the functional circuitry, motor, and ultrasonic atomizing plate.

[0010] Furthermore, the aforementioned medicine chamber is equipped with a sponge, which fully absorbs the medicine and ensures that the medicine and the inner side of the ultrasonic atomizing plate are tightly bonded.

[0011] Furthermore, the aforementioned replaceable atomizing nozzle is equipped with a medicine filling port, through which medicine is added to the medicine tank.

[0012] Furthermore, the toothbrush body has a charging component at its bottom, which is connected to a charger to charge the battery.

[0013] Furthermore, the aforementioned replaceable atomizing nozzle includes a nozzle body and a first connecting rod. The nozzle body is fixed to the upper end of the first connecting rod, and the ultrasonic atomizing plate is located inside the nozzle body. The medicine chamber is disposed inside the first connecting rod, and the medicine filling port is disposed on the back of the first connecting rod.

[0014] Furthermore, the aforementioned replaceable brush head includes a brush head body and a second connecting rod. The brush head body is fixed to one end of the second connecting rod. Brush bristles are fixed on the front side of the brush head body, and a slot is provided on the back side. A buckle that mates with the slot is provided on the nozzle body. The slot and the buckle mate to connect the replaceable brush head and the replaceable atomizing nozzle.

[0015] Furthermore, the lower end of the first connecting rod is provided with an electromagnetic bead, which is connected to the ultrasonic atomizing plate through a wire; the upper part of the toothbrush body is also provided with an electromagnetic bead, which is connected to the functional circuit.

[0016] The magnetic beads of the two components come into contact and generate an adsorption force, which connects the replaceable atomizing nozzle to the toothbrush body. The magnetic beads of the two components also conduct electricity and transmit control signals to the functional circuit, enabling the functional circuit to control the ultrasonic atomizing plate to work.

[0017] Furthermore, the electric toothbrush body is equipped with a power switch, a mode button, and a status indicator light. The power switch, mode button, and status indicator light are connected to the functional circuit. The mode button can control the vibration intensity of the motor and the spray intensity of the ultrasonic atomizing plate. The power switch can control the motor and the ultrasonic atomizing plate to turn on and off. The status indicator light can display the vibration intensity of the motor and the spray intensity of the ultrasonic atomizing plate.

[0018] Furthermore, the aforementioned functional circuit includes an MCU, which generates a PWM wave to drive the motor to rotate, thereby causing the internal mechanical rod to vibrate the brush head at high speed. The MCU also generates a PWM wave to cause the ultrasonic atomizing plate to vibrate at high frequency, thus dispersing and spraying the medicine.

[0019] Advantages of this invention:

This invention provides an electric spray toothbrush with a replaceable atomizing head, which can atomize the toothpaste while brushing, cleaning and polishing the tooth surface with the calcium carbonate and other ingredients in the toothpaste, and deeply cleaning the gums and hard-to-reach areas of the mouth with the liquid in the toothpaste chamber.
