Generally, the toothbrush is used in such a manner that the user applies the toothpaste to the bristles. Then, the tooth in the oral cavity is subjected to a reciprocating brushing movement of the teeth in the mouth of the tooth to grasp the teeth. However, in the process of brushing teeth, it is inevitable that the user will secrete saliva, and the saliva will then produce a liquid with the teeth on the bristles. At this time, the liquid flows out of the mouth and flows through the toothbrush to the K to hold the toothbrush with f. On the hand, it not only stains the user's hand, but also makes the user feel uncomfortable sticky and dirty feeling, which affects the fun of brushing teeth. In view of this, if you can provide a kind of J to avoid the user's hand being brushed by the tooth and the mouth, the toothbrush can be widely used for solving the lack of conventional skills. Favorite. β [New content] The purpose of this creation is to set the plate ^^ 隹 for a flow-through hollow toothbrush, so that when the user uses the toothbrush, the boat a D, the hand holding the toothbrush will not be saliva and toothpaste Contaminated by the mixed liquid. For the above purposes, the guided hollow toothbrush of the present invention comprises a toothbrush head 109218.doc M305619 and a handle. The toothbrush head has a neck portion and a brush holder system disposed on the neck portion, and is hollow to form a flow guiding path extending in the longitudinal direction and extending through the entire length, and the handle is respectively formed at both ends of the flow guiding channel There are - a first opening and a - second opening. The neck of the toothbrush head is partially inserted into the flow guiding passage through the first opening, and has a plurality of ribs 1 connected to the handle along the radial direction of the neck (4) to fasten the toothbrush head to the handle through the rib. And each rib "] is a plurality of flow paths that are coaxially conductive with the flow guiding channel. When using this flow-through hollow toothbrush, the field user holds the handle by hand and then uses the bristle on the head of the toothbrush to clean the teeth in the mouth. During the brushing process, the liquid produced by mixing the saliva with the toothpaste is guided downwardly by the neck of the toothbrush head, and then enters the flow path defined by the ribs in the handle through the first opening. In succession, the liquid flows through the flow path to the flow guiding channel that is coaxially connected. Finally, the liquid flows out through the second opening of the handle. In this way, contamination of the user's hand by the liquid can be avoided. [Embodiment] FIG. 1 is a partial cross-sectional view showing a longitudinal direction of a flow-through hollow toothbrush according to an embodiment of the present invention; and FIG. 2 is a toothbrush of a flow-through hollow toothbrush according to an embodiment of the present invention. A schematic view of a partial structure of the head and neck; and FIG. 3 is a partial plan cross-sectional view of the flow-through hollow toothbrush according to an embodiment of the present invention. As shown in the figure, the guide type hollow toothbrush of the present invention can be used to extract the mixed liquid of the toothpaste and the saliva produced by the toothbrush 10 in a proper manner (as indicated by an arrow in FIG. 1). Do not contaminate the user's hand holding the toothbrush W' to avoid the feeling of discomfort caused by sticky dirt. The flow guiding hollow toothbrush 1 comprises a toothbrush head U and a handle 12. 1092l8.doc M305619 The brush head 11 has a neck portion 111, and the end of the neck portion (1) is provided with a - bristle portion 112. The handle 12 is designed to be hollow to form a guide channel 121 extending in the longitudinal direction and extending in the longitudinal direction, and the handle 12 is respectively formed with a first opening 122 at both ends of the flow guiding channel 121 and a second opening 123. The neck ηι of the toothbrush head u can be partially inserted into the flow guiding passage 121 in the handle 12 via the first opening 122 of the handle 12, and at the neck ill in the insertion handle 12, along the neck U1 Radially extending a plurality of ribs ιΐ3, and the ribs and strips U3 are respectively connected to the inner wall of the handle 12, thereby fastening the neck (1) to the handle 12 through the ribs ι 3, thereby inserting the head of the brush On the handle 12 . In addition, each of the ribs 113 defines a plurality of flow passages 114 between the inner wall of the handle 12 and the neck ill of the head shank, and the flow passages 114 are longitudinally extended and coaxially with the flow guiding passages 121. Moreover, the handle 12 extends radially at the first opening 122 to form a water collecting flange 124, thereby forming a water collecting area at the first opening 122 through the water collecting flange 124, thereby increasing the flow guiding type. Hollow toothbrush 10 Qin water efficiency. Further, the inner wall of the handle 12 can be concave (as shown in Fig. i) to increase the cross-sectional area of the flow passage 114, or just a simple upright wall (as shown in Figs. 2 and 3). When the user uses the flow-through hollow toothbrush 1 , the handle 12 is held by hand, and then the brush portion 112 on the head of the toothbrush is used to clean the teeth in the oral cavity. In the process of brushing, when the height of the handle 12 is lower than the head of the toothbrush, the liquid produced by mixing the saliva with the toothpaste will flow down through the neck 111 of the head of the toothbrush, and then through the handle 12 After the water collecting flange 124 collects the liquid to prevent the liquid from overflowing, the mixed liquid enters the flow path 114 defined by the respective ribs 113 in the handle 12 through the first opening 122. In other words, the liquid flows through the flow path ι 4 to the guide channel 121 which is coaxially extended and electrically connected. Finally, the liquid then flows out through the first opening 123 of the handle 12. In this way, contamination of the user's hand by the liquid can be avoided. Further, in order to keep the liquid flowing smoothly, the ribs 13 are formed on the surface close to the first opening 122 to form a bevel ΐ5, respectively. Therefore, after the liquid enters the first opening 122, it flows into the flow path 114 more smoothly because of the configuration of the inclined surface 115. Further, in order to prevent the liquid from being clogging at the entrance of the flow path 114 and causing the liquid to flow smoothly, the ribs 115 of the ribs 113 are respectively formed with a blade portion 116. The foam is cut through the blade portion 116 to prevent the bubble from clogging. 4A is a schematic cross-sectional structural view of a first embodiment of the present invention, and FIG. 4B is a schematic cross-sectional structural view of a second embodiment of the present invention; 4 is a schematic cross-sectional structural view of a third embodiment of the present invention. As shown in the figure, the shape of the neck of the toothbrush head of the present invention is arbitrarily shaped, such as an elliptical shape (as shown in FIG. 4A) and a rectangle (such as FIG. 4B). Shown) or round (as shown in Figure 4C). The number of ribs 113 for connecting the brush head 11 to the handle 12 is also not limited. For example, two ribs 113 may be placed (as shown in FIG. 4A), and each rib j 13 is disposed at an angle of 120 degrees, such that between the inner wall of the handle 12 and the neck 111 of the toothbrush head 11. Three flow paths 114 are formed. It is also possible to provide only two ribs 113 (as shown in Fig. 4B), and the two ribs 113 are arranged at an angle of 18 degrees, whereby the inner wall of the handle 12 and the neck of the toothbrush head 11 are provided. Two flow paths 114 are formed between the turns. Of course, four ribs 113 (as shown in FIG. 4C) may be provided, and the ribs 113 are disposed at an angle of 90 degrees, thereby forming four flows between the inner wall of the handle 12 and the neck 111 of the toothbrush head 11. Turnout 14. Although the preferred embodiments of the present invention have been described herein, it is apparent to those skilled in the art that various changes and modifications can be made without departing from the invention; therefore, the present invention is intended to be attached The request contains all such changes and modifications within the true spirit and scope of the present invention.
