And secondly, regarding the operating angle of brush head replacement, a guest needs to perform the operation by himself, which needs to consider the operation convenience and the operation accuracy. Even the obverse and reverse of the direction of attachment of the brush head are factors of operability considerations. Thirdly, the reliability of the brush handle and the brush head after connection can meet the limitation of six degrees of freedom (stability after connection) to the maximum extent. Fourthly, the oral mucosa protective device is comfortable in use, and due to the detachable connecting structure, the whole structure cannot have factors causing sharp stimulation of the oral mucosa.

Disclosure of Invention

The utility model discloses to above problem, provide one kind under the prerequisite of advocating resource saving, independently strong operability, connection are firm, use comfortable head toothbrush that trades.

The technical scheme of the utility model is that: the toothbrush comprises a toothbrush handle body and a toothbrush head, wherein a groove is formed in the head of the toothbrush handle body; the toothbrush head comprises a head plate and bristles; the brush head plate is connected in the groove through a detachable structure; the detachable structure comprises at least one clamping groove/protrusion arranged on the side wall of the groove and at least one protrusion/clamping groove arranged on the side face of the brush head plate, and the number and the positions of the clamping grooves/protrusions on the side wall of the groove are matched with those of the protrusions/clamping grooves on the side face of the brush head plate.

The groove is symmetrical in shape, and the shape of the brush head plate is matched with that of the groove.

The bottom surface of the groove is also provided with a hole, and the bottom surface of the brush head plate is provided with a pin column matched with the hole; the pin is inserted into the hole.

Two holes are symmetrically formed in the bottom surface of the groove, and the pin columns on the bottom surface of the brush head plate are arranged corresponding to the two holes in the bottom surface of the groove.

The end of the pin column is in a spherical crown shape, and the edge height of the pin column is lower than or equal to the hole edge of the hole; the height of the spherical crown is higher than or equal to the hole edge of the hole.

The connection structure of the brush handle and the brush head of the utility model adopts groove positioning and buckle connection, and provides reliable guarantee for connection stability in structural form. The brush head plate is convenient to push out by utilizing the slight protrusion of the pin column to carry out disassembly; when the device is installed, the grooves are symmetrically shaped, so that a guest does not need to distinguish the front direction and the back direction when using the device; this improves the operability to some extent. In addition, the slightly protruding end of the pin column is in a spherical crown shape, and a protruding sharp edge and a concave sharp edge are not left, so that the stimulation to oral mucosa is reduced, and the comfort is improved. The utility model discloses starting from the detail, optimizing improvement has been carried out around operability, reliability and travelling comfort to the structure of trading the head toothbrush.

Detailed Description

The present invention will be described in further detail with reference to the accompanying fig. 1-9.

Comprises a brush handle body 1 and a toothbrush head 2, wherein the head part of the brush handle body 1 is provided with a groove 11; the toothbrush head 2 comprises a head plate 21 and bristles; the brush head plate 21 has a certain thickness (e.g., 1-4 mm), and is connected in the groove 11 through a detachable structure; the detachable structure comprises at least one clamping groove/protrusion arranged on the side wall of the groove 11 and at least one protrusion/clamping groove arranged on the side surface of the brush head plate, and the number and the positions of the clamping grooves 111/protrusions on the side wall of the groove 11 are matched with those of the protrusions 211/clamping grooves on the side surface of the brush head plate 21. The statement about a slot/protrusion, protrusion/slot expresses a relative state, such as: when a clamping groove structure is arranged in the groove 11, the side surface of the corresponding brush head plate 21 is a bulge; and vice versa. This type of connection facilitates the complete confinement of the head plate 21 within the recess 11, resulting in a stable connection that is resistant to the pushing and resisting forces of brushing in the vertical and lateral directions during brushing.

The groove 11 is symmetrical, and the shape of the brush head plate 21 is matched with that of the groove 11. For example, the shape of the oval or the standard runway, so that when the device is installed, the front side and the back side can be distinguished regardless of the front side and the back side, and if the device is in an asymmetric shape, the experience of an operator is poor.

The bottom surface of the groove 11 is also provided with a hole 112, and the bottom surface of the brush head plate 21 is provided with a pin 212 matched with the hole 112; the pin 212 is inserted into the hole 112. The pins 212 serve, on the one hand, to enhance positioning and, on the other hand, to facilitate removal, by pushing out the head plate 21 from the pins 212 as a point of force.

Two holes 112 are symmetrically arranged on the bottom surface of the groove 11, and the pins 212 on the bottom surface of the brush head plate 21 are arranged corresponding to the two holes 112 on the bottom surface of the groove 11.

The ends of the pins 212 are spherical crown shaped with an edge height less than or equal to the hole edge of the holes 112; the height of the spherical cap top is higher than or equal to the hole edge of the hole 112. The slightly convex is convenient for pushing out, and the arc surface can not stimulate the oral mucosa.

The present invention is not limited to the above embodiments, and based on the technical solutions disclosed in the present invention, those skilled in the art can make some replacements and transformations for some technical features without creative labor according to the disclosed technical contents, and these replacements and transformations are all within the protection scope of the present invention.
