New description: [New technical field] This creation is about the improved structure of electric toothbrushes, especially the electric toothbrush structure with better cleaning effect. [Prior Art] With the trend of modern people's eating habits and polysaccharides, the probability and degree of injury to teeth are more serious than before, and the awareness of various health care is gradually receiving more attention. 'So' oral and dental care is also increasingly For the attention of people. In the field of traditional oral and dental cleaning products, toothbrushes are indispensable, for example: the attachment of the tooth surface or the residue between the teeth can be properly brushed by the bristles of the toothbrush to maintain cleanliness; Conventional - the toothbrush structure is provided with a bristles at one end of a preset grip, and when used, the bristles are manipulated on the surface of the teeth by hand gripping the grip to generate a rubbing, thereby achieving the above-mentioned brushing of the tooth surface The effect of attachment or inter-tooth interstitial residue, however, such a conventional toothbrush structure needs to be operated by a human hand, which is inconvenient for a person who is slow in motion or inconvenient to move, and, because of the operation of the toothbrush by hand The angle and the speed of movement are all limited. Therefore, even if the above-mentioned conventional toothbrush structure is continuously improved for the shape and curvature of the handle or the bristles, it is still difficult to effectively meet the cleaning needs of the modern people for the mouth and the teeth, so how can Before the convenience of use, quickly and pro-effectively clean the cavity and teeth, but (4) the applicants need to work hard = M314031 EC toothbrush structure of the above-mentioned shortcomings, is the creator of these shortcomings for the improvement of the study road, and finally the creation of this production. [New content] The main purpose of the present invention is to provide an improved structure of an electric toothbrush, which has two independent brush head structures, and the two brush heads have different motion modes, which can produce an optimal cleaning effect. In order to achieve the above objectives and effects, the technical means adopted by the present invention includes: a grip having an opening on the top side, and a drive shaft driven by a preset power source in the opening, and the drive shaft The end portion is provided with an off-axis eccentric rod, a toothbrush head seat, and a side space recessed with an accommodating space, wherein the bottom of the toothbrush head base is coupled to the opening of the gripper, so that the driving eccentric rod can be inserted into the end In the accommodating space, a plurality of symmetrical guiding sliding protrusions are disposed on the side of the outer periphery of the accommodating space; a second brush head is affixed with bristles on the front side of the one-piece body, and the second brush head is The top and bottom sides are respectively provided with at least one upper φ and a lower tab, and the lower tab can be hooked on the bottom side of the accommodating space of the toothbrush head seat, and a concave portion is disposed on the top side edge of the upper tab. A plurality of guide grooves and a channel are disposed on the back side of the body, and the guide groove can be fitted to the guide sliding protrusion of the toothbrush head seat to form a traverse guide, and the channel can be fitted to the drive shaft An eccentric rod capable of interlocking the second brush head to generate a lateral reciprocating motion by using the rotation of the eccentric rod Sliding; a first brush head is attached to the front side of the piece body with bristles, and a shaft hole is arranged in the center of the body for a pivot to pass through the valley space of the toothbrush head seat Blocking the tab on the second brush head, and the back side of the first brush head is further provided with a protrusion adjacent to the shaft hole, and can protrude from the concave portion of the tab above the M314031. The second purchase of the reciprocating traverse moves the batch by the upper tab, so that the first brush head is pivotally centered and the arc is reciprocatingly turned. For the detailed construction, application principle, function and effect of this creation, “?, the following can be fully understood according to the drawing: [Embodiment] The structural decomposition diagram of the creation is based on The second and third figures of the H-view and the side-view partial combination section can be (4) clearly show that the second brush vine should include: grip 1, toothbrush head seat 2, first-brush head 3 and neck ΐ 1 Partially, wherein the top side of the grip 1 is provided with an outer diameter tapered, a σ is provided above the rider 11, a coupling groove 111 extending inward of the opening, and a snap-on fishing η 2 There is a power source (not shown) in the Ί二二ί, which can drive the drive shaft to the inside of the 4 opening and is provided with a deviation from the end of the drive shaft 1 2 * 1 1 1 'brush head holder 2 - the side recessed - has an opening in the 3, (4) the accommodating space 23 is provided with a screw hole 231, ? i ^ 2 2 the outer circumference of the two sides are provided with a plurality of symmetrical guiding sliding protrusions 9 The two sides of the toothbrush head base 2 are oppositely provided with a combined rib 2 1 and a η 仙. The combined rib 2 1 is extended to the shoulder of the joint 1 and the ym is matched with the card 掣 掣 1 1 1 2 2 2 2 2 2 2 Can make this The brush head holder is fixed to the fastening base 2] Xi is called the receiving space 23, the second, and the brush drive shaft 12 extends into a large brother 4 lines before a sheet-like main body side explants M314031

The lower tabs 45 can be embedded in the bottom side of the accommodating space 2 3 of the toothbrush head holder 2 , and the upper side The top side edge of the tab 4 3 is provided with a recess 4 31 ′ on the back side of the main body of the second brush head 4 , and a plurality of guide slots 44 and a channel 4 1 extending perpendicularly to each other in the horizontal direction are horizontally disposed. The groove 4 4 can be fitted to the guide sliding portion 24 of the toothbrush head holder 2 to form a lateral guiding guide, and the channel 4 1 can be fitted to the eccentric rod 1 2 1 of the driving shaft 1 2 . The brush head 3 is flanked by a bristles 3 2 on the side of a circular sheet-shaped body, and a shaft hole 3 is disposed in the center of the body for a pivot 3 丄丄 to be penetrated at the end of the pivot 31 1 The external thread 3 1 2 is configured to be screwed into the screw hole 2 3 1 in the accommodating space 2 3 of the toothbrush head holder 2 to form a pivotable position, and the first brush head 3 can be blocked by the second The upper surface of the first brush head 3 is further provided with a protrusion 3 3 which can protrude from the second brush head 4 on the back side of the first brush head 3 In the recess 4 3 1 of the upper tab 4 3 , on the side of the protrusion 3 3 The side button has a protruding post 3 4 . The fourth and fifth figures are partial combined sectional views and motion diagrams before the creation. As shown in the two figures, when the driving shaft 丄 2 drives the eccentric rod 丄 2 丄 rotation: the second brush head can be linked via the channel 4 i 4, a lateral reciprocating slip occurs. At this time, the second brush head 4 can interlock the studs 3 3 via the recesses 4 3 1 of the upper tabs 4 3 so that the first brush head 3 is centered on the pivots 3 and i. In the above-mentioned action, the bristles of the second brush head 4 generate a lateral reciprocating slip, and the bristles 3 2 of the first brush head 3 have a curved reciprocating swing and are convex on both sides. The brace 3 4 limits the angle of rotation of the two 3, and uses the combination of the above different actuation modes to remove the tartar effect by the M314031. It can be seen from the above that the improved structure of the electric toothbrush of the present invention can utilize different independent brush heads to produce different action forms, thereby achieving the effect of better cleaning effect, and indeed has industrial applicability, novelty and progressiveness. However, the above description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.
