The specific embodiment

Provide embodiment of the present utility model below, and be described with reference to the accompanying drawings.The outside drawing of brush body in this embodiment can be referring to Fig. 1, and the outside drawing of the cradle that matches with brush body can be referring to Fig. 2.

The composition of brush body and cradle is described respectively below.Referring to Fig. 3, Fig. 3 is the explosive view of brush body outward appearance, and in this embodiment, brush body comprises body loam cake 1, body lower cover 2, toothbrush cover 3, ultrasonic vibration sub-prime 4, little induction coil 5, PCBA body 6, motor bracket 7, motor cover 8, motor 9 compositions.The composition of cradle includes cradle lower cover 10, PCBA cradle 11, big induction coil 12, cradle loam cake 13 referring to Fig. 4.

Describe the composition of above-mentioned each part and mutual being connected in detail below in conjunction with accompanying drawing.When mounted, as shown in Figure 5, motor 9 is put silica gel sheath be assembled in the motor bracket 7, and the motor cover 8 with grab is installed in the corresponding position of installation motor 9 on motor bracket 7.Control circuit in the brush body is arranged in PCBA body 6, and the corresponding position that again PCBA body 6 is installed to motor bracket 7 fastens, and rechargeable battery is put in the cylindrical cavity in the motor bracket 7, little induction coil 5 is sleeved on connecting rod 71 places of motor bracket 7.At last, assemble and be nested in the body lower cover 2.

When body lower cover 2 was connected with body loam cake 1, as shown in Figure 6, the draw-in groove 101 by grab on the body lower cover 2 201 and body loam cake 1 was interlocked.

As shown in Figure 7, the draw-in groove position of body loam cake 1 has the groove of along the circumferential direction going up 102, is used to install fluid sealant, after body loam cake 1 and body lower cover 2 fasten, realizes favorable waterproof property by groove 102 fluid sealants.

Certainly, the groove that is added in that the switch panel place is installed, is offered groove 103 incessantly at the closed position place of body loam cake 1, as shown in Figure 8, is used to add fluid sealant, and realization is bonding with on and off switch, realizes the good function that discharges water in the cavity.

In this embodiment, assembling for ease of brush body, on body lower cover 2, offer U type opening 202, as shown in Figure 9, offer slot on U type interface, when being connected with body loam cake 1, the inserted sheet of body loam cake 1 is inserted in the slot, realize connecting, also can in slot, add fluid sealant and then realize bonding.

After body loam cake 1 and body lower cover 2 connected, body loam cake 1 is installed ultrasonic vibration sub-prime 4, and put toothbrush cover 3, the final brush body profile that forms as shown in Figure 1.

Brush body among this embodiment, by on the groove of offering on the body loam cake 1 102, groove 103, adding fluid sealant, can guarantee to form between body loam cake 1, the body lower cover 2 sealing of cavity, prevent that the globule on the brush body is flow in the cavity by gravity effect, thereby cause the electronic installation in the cavity to break down; By for motor adds silica gel sheath, can effectively reduce brush body noise in the course of the work.

Describe the structure of brush body above in detail, describe the structure of cradle below in detail, as shown in Figure 4, during connection, big induction coil 12 is packed in the cradle loam cake 13, again PCBA cradle 11 is fixed in the cradle loam cake 13, at last cradle lower cover 10 and cradle loam cake 13 are fastened.

By the little induction coil 5 on big induction coil 12 and the brush body on the cradle, can realize the wireless charging of battery on the brush body.During charging, after the cradle energized, brush body is inserted in the cradle,, can realizes the quick charge of rechargeable battery on the brush body by big induction coil 12 and little induction coil 5.Owing to adopt wireless charging, can reduce the replacing number of times of battery, convenient in the use.Certainly, if adopt common batteries, do not influence the realization of present embodiment.

Be provided with the circuit that comprises big induction coil in cradle, its circuit diagram can be referring to Figure 10, and Figure 11 by these two kinds of circuit, can realize connecting the power supply of 220v and 110v.After cradle connects power supply, after the alternating current process C1 blood pressure lowering, after heap (DB) rectification of passing a bridge, give the power supply of LC oscillating circuit, thereby make big induction coil generation induction electromotive force.

When needs charge, brush body is inserted in the hole of cradle, cradle produces induction electromotive force by big induction coil to be responded to the little induction coil on the brush body, and little induction coil is converted to the rechargeable battery charging of electric current for connecting with induction electromotive force.

Circuit structure diagram on the brush body can for clearly representing the circuit diagram of brush body, be split as Figure 12 A, Figure 12 B with this circuit diagram referring to Figure 12 A, Figure 12 B.The connecting method of Figure 12 A, Figure 12 B can be referring to Figure 13, and Figure 12 A, the setting-out of Figure 12 B side point are cut-off rule.When pressing on and off switch SW1, supply with trigger impulse of IC, make IC the 7th foot change high level into, audion Q1 conducting, motor action by low level; Make IC the 5th foot change low level into by high level simultaneously, audion Q2 conducting is the ultrasonic circuit module for power supply, and the indication red light (red) that connect this moment is bright, and lc circuit resonates with the vibration sub-prime, produces ultrasound wave.Producing hyperacoustic time can set by the RC circuit of IC inside, in the present embodiment, is 3 minutes, certainly, also can change as required.

When charging, little induction coil is divided into 3 the tunnel after sensing voltage from big induction coil, leads up to R1, makes indication green light (green) bright; Lead up to the D2 rectification, through giving the NI-MH battery charge after the C1 filtering; The D1 of leading up to gives the power supply of IC the 3rd foot, makes IC the 7th foot change low level into by high level, and Q1 ends, if motor in working order at this moment, will stop action; Simultaneously, IC the 5th foot changes high level into by low level, and Q2 ends, and battery stops to be the ultrasonic circuit power supply that red light extinguishes.

Describe the component relationship and the work process of this utility model toothbrush various piece above in detail; for the toothbrush of being set forth among the embodiment; all within spirit of the present utility model and principle; any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
