Description

Technical Field

[0001] The utility model relates to the technology of charger field, in particular to a DC charging seat for an electric toothbrush. Background Art

[0002] The electric toothbrush generates high-frequency vibrations through the rapid rotation or vibration of the motor core, which instantly breaks down the toothpaste into fine foam and deeply cleans the gaps between teeth. At the same time, the vibration of the bristles can promote blood circulation in the oral cavity and massage the gum tissue. There are generally two types of electric toothbrushes. One type uses dry batteries as a power source, but the voltage of dry batteries is low and they need to be replaced regularly, which brings a lot of trouble to the use of electric toothbrushes and increases the cost of using electric toothbrushes. The other type is a rechargeable electric toothbrush, which is equipped with a charging stand to charge the electric toothbrush.

[0003] The general structure of the charging stand on the market is as follows: the top of the charging stand has a cavity that is sunken into the charging stand, an outer coil is arranged just below the cavity, a hollow cylinder with an upward protrusion in the middle is arranged in the cavity, an inner coil surrounding the hollow cylinder is arranged outside the hollow cylinder, and a magnetic bar is arranged in the hollow cylinder, the upper part of the magnetic bar is inserted into the hollow cylinder, and the lower part is located in the middle of the outer coil. This design in which the inner and outer coils are distributed vertically up and down, and the magnetic bar is not completely placed in the inner coil, makes it impossible for the magnetic bar to fully cause the inner and outer coils to perform electromagnetic induction, resulting in a weak electromagnetic induction intensity, so that the charging stand cannot quickly charge the electric toothbrush, the conversion speed of electrical energy and magnetic energy is slow, and the charging time is too long, which is not convenient for the use of the electric toothbrush. Utility Model Content

[0004] In view of this, the utility model aims to solve the deficiencies in the prior art, and its main purpose is to provide a DC charging stand for an electric toothbrush, which can effectively solve the problem that the magnetic rod of the existing charging stand cannot fully enable the inner and outer coils to undergo electromagnetic induction, resulting in weak electromagnetic induction intensity, thereby making it impossible for the charging stand to quickly charge the electric toothbrush, the conversion speed between electrical energy and magnetic energy is slow, the charging time is too long, and it is inconvenient to use the electric toothbrush.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A DC charging stand for an electric toothbrush comprises a shell, a PCB board, a magnetic rod, a first coil and a wire; the shell has a receiving cavity, the top surface of the receiving cavity is concave inside and convex outside to form a mounting portion, the PCB board is arranged in the receiving cavity, the magnetic rod is arranged inside the mounting portion, the first coil is sleeved on the magnetic rod and is located on the same plane as the magnetic rod; the wire is connected to the PCB board, one end of the wire extends into the receiving cavity, the other end of the wire extends outside the shell, and the other end of the wire is connected to a USB interface.

[0007] As a preferred solution, the housing includes an upper shell and a lower shell, which are assembled with each other to form the aforementioned accommodating cavity, and the mounting portion is formed on the top surface of the upper shell with a concave inside and a convex outside.

[0008] As a preferred solution, the shell is made of ABS material.

[0009] As a preferred solution, a fixing portion is provided at one end of the wire, a plurality of slots are provided on the fixing portion, and the housing has a plurality of buckle portions, each buckle portion is buckled and fixed with a corresponding slot.

[0010] As a preferred solution, a plurality of anti-slip pads are provided at the bottom of the housing.

[0011] As a preferred solution, a limiting portion is extended outwardly from the peripheral side surface of the mounting portion, and the design of the limiting portion can prevent the electric toothbrush from rotating during charging, thereby causing position deviation.

[0012] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0013] The first coil is sleeved on the magnetic rod and is located on the same plane as the magnetic rod, and a mounting portion is formed by the top surface of the accommodating cavity being concave inside and convex outside. The magnetic rod is arranged inside the mounting portion. When the electric toothbrush is charged, the second coil installed on the handle of the electric toothbrush is located on the same plane as the first coil and the magnetic rod, so that the magnetic rod can more fully cause the first coil and the second coil to undergo electromagnetic induction, thereby increasing the intensity of the electromagnetic induction. This allows the charging stand to quickly charge the electric toothbrush, speeding up the conversion of electrical energy and magnetic energy, shortening the charging time, and facilitating the use of the electric toothbrush.
