Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 to 4, an embodiment of the present utility model provides a safety toothbrush, comprising: a brush head 3 and a toothbrush handle 1; the toothbrush handle 1 comprises a holding part 11, a blocking abutting part 12 and a neck part 13; a bending part with a preset included angle between the holding part 11 and the blocking abutting part 12; the blocking abutment 12 is used to prevent the toothbrush head 3 from penetrating too far into the mouth; the neck 13 is arranged on top of the blocking abutment 12, the neck 13 being provided with a brush head 3; the brush head 3 at least comprises a brush hair seat 31, wherein the brush hair seat 31 is provided with brush hair clusters 33, and the brush hair clusters 33 are provided with a plurality of brush hair. According to the embodiment of the utility model, the position and the orientation of the toothbrush are fixed through the holding part 11 and the blocking abutting part 12, and the orientation of the toothbrush head is kept parallel to the tooth direction angle by clamping the palm and tiger mouth part, so that the problems that the user has a cognitive disorder in the hand direction or the child learning to brush teeth in early stage can not flexibly distinguish the front side from the back side are solved. The following provides a detailed description of the deployment of a safety toothbrush in accordance with embodiments of the present utility model.

As shown in fig. 1 to 8, in the embodiment of the present utility model, according to the initial stage of child growth, after the palm grips the grip portion in an ergonomically designed angle, the bottom of the blocking abutment portion 12 has a good supporting effect, and in addition, the neck portion 13 is disposed at the top of the blocking abutment portion 12, so that the extending direction of the neck portion 13 and the palm of the safety toothbrush are on approximately the same horizontal plane, and during the brushing action of the safety toothbrush, the direction of the toothbrush head is always parallel to the angle of the gum direction, and the toothbrush head is kept parallel to the angle of the tooth direction without frequent rotation of the wrist, thereby playing a role in brushing and saving power. The safe toothbrush can assist children to stably hold the toothbrush in the tooth brushing action process of the safe toothbrush provided by the utility model, so that the wrist or the elbow of the children can easily send the brush head 3 to the oral cavity without excessive bending, and the children can more easily use the safe toothbrush to quickly learn to brush teeth, thereby greatly increasing the self-brushing purpose of the children. On the other hand, the holding part 11 and the blocking abutting part 12 form a bending part at a preset included angle, and the top of the blocking abutting part 12 is used as a blocking object to prevent the toothbrush handle 1 from being too much plugged into the mouth of a child, so that potential safety hazards of damaging the mouth are effectively prevented. During the brushing action of the safety toothbrush, the blocking abutting part 12 fixes the gripping height, and the residual safety slave length of the toothbrush head can be maintained without adding a toothbrush safety blocking piece. Solves the problem that the left toothbrush length is too long when brushing teeth, which causes the careless penetration into the throat and the pharynx because the grasping length of the common toothbrush is not limited or is not easy to control.

As shown in fig. 1 to 8, in the embodiment of the present utility model, the central axis of the neck 13 coincides with the center of the blocking abutment 12; the bottom of the blocking abutting part 12 is used for abutting the tiger mouth of a hand.

As shown in fig. 1 to 8, in the embodiment of the present utility model, further, in order to effectively maintain the stability of the holding during brushing, a return bend portion 14 for abutting against the back of the hand is further provided on the outer side of the blocking abutting portion 12, and the extending direction of the return bend portion 14 is on the same side of the blocking abutting portion 12 as the extending direction of the holding portion 11. For example, the extending direction of the bending back portion 14 is substantially the same as the extending direction of the grip portion 11; the bending back part 14 and the toothbrush handle 1 form a groove 16 for accommodating the tiger mouth part. Through the back bending part 14 which is used for abutting against the back of the hand and the groove 16 which is used for accommodating the tiger mouth part, the probability of rotation and hand-off which are difficult to occur in the tooth brushing process is effectively reduced, and the children who brush teeth just can conveniently master the tooth brushing capability rapidly.

As shown in fig. 1 to 8, in the embodiment of the present utility model, the comfort is further increased, and the width of the groove 16 is set to be equivalent to the thickness of the palm. During the action of brushing teeth by using the safety toothbrush, the grooves 16 are attached to the positions of the tiger mouth of the main palm of the card. Too large a distance, the clamping tiger is too loose, and the tiger is easy to shake and deviate from the tooth direction during brushing. Too small a distance, so that the clamping tiger mouth is too tight, and the palm is injured in the brushing process. Typically, a palm of a child aged 1-12 years has a thickness of 16-26mm, and the width of the recess 16 is preferably 18-28mm for increased comfort. The palm thickness of a 12 year old child to adult is 26-36mm and the width of the grooves is 28-38mm for added comfort.

As shown in fig. 1 to 8, in the embodiment of the present utility model, the distance between the center of the mouth and the farthest saw teeth of a typical 1-12 year old child is about 25-35mm, and the distance between the mouth and the sensitive area of the pharynx is about 55-60 mm, so that in order to ensure that each tooth can be cleaned, the toothbrush handle 1 is prevented from being excessively inserted into the mouth of the child to cause oral injury or nausea and vomiting, and the height h of the neck is 30-52mm. The straight line distance from the center of the mouth to the farthest saw teeth of a 12-year-old child to an adult is about 40-65mm, the straight line distance from the mouth to the sensitive area of the pharynx is about 75-85 mm, and the height h of the neck is 42-68mm in order to avoid nausea and vomiting caused by excessive insertion of the toothbrush handle 1 into the oral cavity.

As shown in fig. 1 to 8, in the embodiment of the present utility model, the height H of the grip portion corresponds to the palm width. The "grip length" of the palm of a child aged 1-12 is about 40-65mm. In order to ensure that the contact surface between the palm and the toothbrush handle is reduced in the tooth brushing process, so that the friction force is insufficient and the toothbrush handle is easy to fall off in the brushing process, the height H of the holding part is preferably 40-65mm. The "grip length" of the palm of an adult aged 12 years is about 65-85mm. In order to ensure that the contact surface between the palm and the toothbrush handle is reduced in the tooth brushing process, so that the friction force is insufficient, and the height H of the holding part of the adult toothbrush inconvenient to brush teeth is 65-85mm.

As shown in fig. 1 to 8, in the embodiment of the present utility model, the width D of the grip portion is equivalent to the hand grip width. The width D of the holding part is too wide, and the palm cannot be closed after holding, so that the brushing is laborious. The width D of the holding part is too narrow, and a gap exists between the palm and the toothbrush handle after the holding part is held, so that the toothbrush can shake after being brushed, and the tooth brushing force is not facilitated. The "grip width" of the palm of a child aged 1-12 is about 25-35mm. In order to avoid the above problems, the width of the grip portion is 25-35mm. The "grip width" of the palm of an adult aged 12 years is about 35-45mm. For an adult toothbrush, the width of the gripping portion is 35-45mm.

As shown in fig. 1-10, the barrier abutment is a flexible barrier for further comfort. Further, the blocking abutment is a soft gel blocking portion or a silicone blocking portion. As shown in fig. 1-10, the grip portion has a wider bottom width than the top portion for further comfort.

As shown in fig. 1 to 8, in the embodiment of the present utility model, in order to further improve economy, the brush head 3 is detachably mounted to the blocking abutment 12 by a detachable neck 13. The brush head 3 can be replaced at any time after being damaged. Specifically, the bottom of the neck 13 is provided with an abutment boss 131, and the bottom of the neck 13 is provided with a hollow recess 130; the blocking abutting part 12 is provided with a through hole 120, and the abutting boss 131 abuts against the top of the blocking abutting part 12; the bottom of the blocking abutting part 12 is further provided with a plug 123 matched with the hollow recess 130, and the plug 123 passes through the through hole 120 and is fixedly connected with the hollow recess 130. Further, for easy disassembly, an internal thread is provided in the hollow recess 130, and the plug 123 is provided with an external thread, and the plug 123 is screwed with the hollow recess 130. It will be understood that in the embodiment of the present utility model, the plug 123 and the hollow recess 130 may be fastened by a snap fit. In another embodiment of the present utility model, an abutment boss 131 is disposed at the bottom of the neck 12, and a plugging portion is disposed at the bottom of the neck 12; the blocking abutting part 12 is provided with a through hole 120, and the abutting boss 131 abuts against the top of the blocking abutting part 12; the bottom of the blocking abutting part is also provided with a plug connector matched with the plug part, and the plug connector is provided with a hollow recess; the plug connector passes through the through hole and is clamped with the hollow concave of the plug connector.

In the embodiment of the present utility model, as shown in fig. 1 to 8, the brush head 3 and the toothbrush handle 1 are integrally formed for further improving stability.

In summary, the safety toothbrush provided in the embodiment of the utility model fixes the position and the orientation of the toothbrush through the bending part with the predetermined included angle between the holding part and the blocking abutting part of the toothbrush handle, and makes the orientation of the toothbrush head parallel to the tooth direction angle by clamping the palm tiger mouth part, so as to solve the problems that the hand direction is cognized, or the front and back sides of the toothbrush cannot be flexibly distinguished in early learning of brushing teeth of children. The safe toothbrush can assist children to stably hold the toothbrush in the tooth brushing action process of the safe toothbrush provided by the utility model, so that the children can easily send the brush head to the oral cavity without excessive bending of the wrists or the elbows of the children, and the toothbrush can be used for rapidly learning to brush teeth more easily. In the action process of brushing teeth by using the safety toothbrush, the blocking abutting part is fixed in gripping height, and the residual safety slave length of the toothbrush head can be maintained without adding a toothbrush safety blocking piece part. Solves the problems that the grip length of the common toothbrush is not limited or the control is not good, and the residual length of the toothbrush is too long when brushing teeth, so that the toothbrush is carelessly penetrated into the throat to hurt the pharynx. .
