Description

Interdental brush

Technical Field

The utility model relates to an oral cavity cleaners and polishes technical field especially relates to interdental brush.

Background

The slit toothbrush is similar to a common toothbrush in that the slit toothbrush is divided into a toothbrush head and a toothbrush handle, and the biggest difference is only the design of the toothbrush head. The brush head of the slit brush is in a cone shape, has models with different sizes, is suitable for slits between teeth with different widths, and can be selected to clean the slits between the teeth according to the requirements. The brush handle of the tooth gap brush is divided into a long brush handle and a short brush handle, when the brush handle of the tooth gap brush is not damaged, only the brush head needs to be replaced periodically, and the tooth gap brush is very convenient and practical.

The tooth gap brush special for cleaning the tooth gap in the oral cavity is suitable for cleaning food residues in the tooth gap, has good use effect, is easy to popularize, and is beneficial to protecting oral hygiene and teeth of people; the prior tooth gap brush has the following defects when in use: 1. in clinic, when a patient uses the interdental brush, the interproximal spaces of teeth still cannot be cleaned, and particularly, more soft dirt and bacterial plaque are visible on the tongue side; 2. when the slit toothbrush is used, the patient can more easily clean the labial side and the buccal side, and the lingual side is inconvenient to use or can not be used to habit; 3. the conventional interdental brush is large, the bristle tip is short, and the root is long. However, in the posterior dental region, the tooth surface often has a sunken root surface, which is easy to leak and cannot be thoroughly cleaned.

Therefore, there is a need to provide a new interdental brush to solve the above technical problems.

Detailed Description

The present invention will be further explained with reference to the drawings and the embodiments; as used herein, the term "distal" refers to the end distal to the tongue of the user and "proximal" refers to the end proximal to the tongue of the user.

Referring to fig. 1 to 4, the interdental brush includes:

a hand-held assembly 1;

the brush gap component 3 is arranged on the handheld component 1 through the connector 2, and the brush gap component 3 is used for cleaning the tooth gap;

the brush slit assembly 3 comprises a support rod, and a plurality of sets of bristles arranged around the support rod, wherein for convenience of description, each set of bristles comprises distal bristles 31, middle bristles 32 and proximal bristles 33 (the number of the distal bristles 31 and the proximal bristles 33 is smaller than that of the middle bristles 32, but the length of the distal bristles 31 and the proximal bristles 33 is larger than that of the middle bristles 32), the distal bristles 31 are positioned on the support rod close to the connector 2, and the ends of the bristles are slightly inclined away from the connector 2; the middle bristles 32 are arranged perpendicular to the support rod, and the length of the middle bristles 32 is gradually increased from the far end to the near end and then gradually decreased; the length of the proximal bristles 33 is equal to or similar to the length and number of the distal bristles 31, except that the ends of the proximal bristles 33 are inclined in the direction of the connector 2 (the bristle ends of the proximal bristles 33 are inclined in the opposite direction to the bristle ends of the distal bristles 31).

It should be noted that: when cleaning the slit between the teeth and the tooth surface, a user operates the hand-held component 1 by holding, inserts the slit brushing component 3 into the slit between the teeth along the slit between the teeth, and swings the hand-held component 1 up and down along the slit between the teeth to enable the slit brushing component 3 to slide along the slit between the teeth in a reciprocating manner, so that the slit between the teeth is cleaned effectively; (1) because the length of the middle brush hair 32 is gradually increased from the far end to the near end and then gradually decreased, the middle brush hair 32 can clean the slits of the teeth and can also care for the tooth surface on the side of the slits of the teeth in the process of pulling the middle brush hair 32 back and forth, so that the cleanness of the dents on the face of the slits of the teeth is improved; (2) because the lengths of the far-end bristles 31 and the near-end bristles 33 are greater than that of the middle bristles 32, the near-end bristles 33 can contact the lingual side of the slit in the process of swinging the slit brushing assembly up and down, the tail ends of the near-end bristles 33 incline towards the direction (labial side and buccal side) of the connector 2, and the lingual side of the slit can be cleaned by the near-end bristles 33 in the process of pulling the near-end bristles 33 outwards; (3) the distal end bristles 31 can contact the labial side and the buccal side of the interdental space, the ends of the distal end bristles 31 are inclined away from the direction (labial side and buccal side) of the connector 2, and the labial side and the buccal side of the interdental space are cleaned by the distal end bristles 31 in the process of pushing the distal end bristles 31 inwards. This slit brush improves the setting of brush hair (setting length, setting angle and quantity of brush hair) to can also look after slit itself, slit face, slit tongue side and slit lip side, buccal side when handling slit, promote the clean effect to the tooth comprehensively.

In an embodiment of the present invention, referring to fig. 3, the handheld component 1 includes a connecting head 11, a connecting rod 12, a handheld rod 13 and a connecting cavity 14, the connecting head 11 is fixedly connected to the handheld rod 13 through the connecting rod 12, the bottom of the connecting head 11 is provided with the connecting cavity 14, the fixed end of the connector 2 is fixed on the supporting rod of the brush seam component, and the connecting end of the connector 2 is installed in the connecting cavity 14 provided in the connecting head 11;

in this embodiment, the connector 2 may be a threaded rod or a sliding rod sleeved with a damping rubber sleeve, when the connector 2 is a threaded rod, the connection cavity 14 formed at the bottom of the connector 11 is a threaded cavity, and the threaded rod is rotated to fixedly connect the threaded cavity formed in the connector 11 with the threads, and when the connector 2 is a sliding rod sleeved with a damping rubber sleeve, the connection cavity 14 formed at the bottom of the connector 11 is a sliding cavity, and the sliding rod is inserted into the sliding cavity formed in the connector 11, so that the damping extrusion effect of the damping rubber sleeve is utilized to improve the mutual fixing effect; and both of these ways facilitate removal of the brush slot assembly 3 and the tooth surface cleaning elements 4.

In an embodiment of the present invention, referring to fig. 4, a silicon sheet 5 is fixedly embedded at the top of the connector 11, and a plurality of rubber protruding balls 6 uniformly distributed are embedded on the silicon sheet 5;

it should be noted that: the tongue can be brushed by using the rubber convex ball 6 on the silicon sheet 5 so as to reduce the residue on the tongue coating.

In an embodiment of the utility model, as shown with reference to fig. 4, still be equipped with antiskid 7 on the handheld pole, antiskid 7 is convenient for the operator fixed gesture in the use, prevents to skid, causes the injury of slit brush to the slit between the teeth.
