Description

Technical Field

[0001] The utility model relates to the technical field of oral care, in particular to a toothbrush with a double-layer cleaning mode. Background Art

[0002] In daily oral cleaning and care, the Bass brushing method is usually recommended for scientific brushing. Choose a soft-bristled toothbrush, hold the toothbrush at a 45° angle to the long axis of the tooth, pointing it in the direction of the root apex (upward for maxillary teeth and downward for mandibular teeth), and press the junction of the gums and teeth so that part of the bristles enters the gingival sulcus and part is spread on the gingival margin, extending as far as possible into the interproximal space. Use gentle pressure to make the bristles vibrate horizontally in the original position for a short distance in the front-to-back direction four to five times.

[0003] Currently, toothbrush heads are mainly cleaned by bristles, however, the bristles are generally soft and cannot clean the tooth surface more thoroughly, which leads to the appearance of smoke and tea stains on teeth, resulting in the rapid accumulation of dental plaque, which poses a serious threat to oral and gum health.

[0004] In the prior art, ultrasonic cleaning or tooth brushing is commonly used for cleaning, which has a good effect on the above-mentioned problem. However, it requires more time and economic costs, is difficult to maintain the effect of regular cleaning, and cannot meet the daily cleaning needs of users. Utility Model Content

[0005] The utility model aims to provide a toothbrush with a double-layer cleaning method to solve the technical problem in the prior art that the bristles of the toothbrush are relatively soft and it is difficult to clean the tooth surface more thoroughly.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 As shown, the utility model provides a toothbrush with a double-layer cleaning method, including a brush handle 10, a brush head 20 is fixedly arranged at one end of the brush handle 10, a replacement head 30 is movably mounted on the brush head 20, a brush sheet 21 is fixedly arranged on the brush head 20, a bristle group 31 is fixedly mounted on the replacement head 30, the brush sheet 21 and the bristle group 31 are staggered and interlaced so that the replacement head 30 and the brush head 20 are movably abutted to form a double-layer scraping brush structure.

[0026] The utility model adopts a detachable double-layer scraping brush structure in the form of an active connection. The silicone brush sheet and the bristles are alternately arranged to enhance the cleaning of the tooth surface while brushing the teeth. The bristles are used for daily cleaning of the gingival sulcus through the Bass brushing method. The silicone brush sheet of the second step is pushed horizontally to achieve the purpose of physical scraping and enhancing the cleaning effect on the tooth surface. The brush part that is easy to deform and consumes quickly is easy to disassemble and replace, which is beneficial to reducing replacement costs and consumption by replacing the head.

[0027] By staggered arrangement of the brush blade 21 and the bristle group 31, it is beneficial to add a scraping method while brushing with a traditional brush, enhance the cleaning of the tooth surface by physical horizontal pushing, reduce the formation of smoke stains and tea stains, thereby reducing the rapid accumulation of dental calculus, and achieving the purpose of enhancing the oral cleaning effect.

[0028] like Figure 1 As shown, the brush sheet 21 includes a protrusion 211 fixedly mounted on the upper surface of the brush head 20, and a silicone sheet 212 is fixedly mounted on the protrusion 211, and the longitudinal section of the silicone sheet 212 is an isosceles triangle structure.

[0029] The protrusion 211 facilitates enhancing the stability of the bottom of the brush sheet 21, and the silicone sheet 212 enables the upper end of the brush sheet 21 to enhance the cleaning of the tooth surface through the soft silicone. The silicone sheet 212 is pushed horizontally on the tooth surface in conjunction with the Bass brushing method. The silicone sheet 212 can be pushed and scraped horizontally on the tooth surface through both sides of the silicone sheet 212, thereby reducing the accumulation of tooth stains and even tartar.

[0030] like Figure 2 and Figure 4As shown, the replacement head 30 is provided with slots 32 that match the brush piece 21 at equal intervals, the slots 32 and the bristle group 31 are arranged alternately, and the slots 32 and the protrusions 211 are movably engaged to form a fixed structure.

[0031] By engaging the slot 32 with the protrusion 211, the replacement head 30 can be easily fixed on the brush head 20 for convenient assembly and installation. During daily use, the bristles are consumed quickly and easily deformed, and need to be replaced regularly. By replacing the replacement head 30, the replacement cost and replacement loss can be reduced.

[0032] like Figure 1 As shown, the width of the replacement head 30 is greater than the width of the brush head 20 , and the height of the upper surface of the silicone sheet 212 is one third to one half of the height of the bristle group 31 .

[0033] The edge of the replacement head 30 protrudes from the edge of the brush head 20, so when replacing, the replacement head 30 can be easily lifted up and separated from the brush head 20 for easy disassembly.

[0034] The height of the silicone sheet 212 is convenient for matching the shape of the bristle group 31 when in use. When brushing teeth, the bristle group 31 contacts, presses and rubs against the teeth, causing the tip of the bristle group 31 to bend and deform, thereby allowing the tip of the silicone sheet 212 to contact the tooth surface for use, making it convenient for the user to manually adjust the strength and angle of the scraping brush. The height setting makes it easy to control the degree to which the silicone sheet 212 scrapes the tooth surface, and it is not easy to cause excessive friction to the tooth surface.

[0035] like Figure 2 , Figure 3 and Figure 4 As shown, a groove 11 is formed at one end of the brush handle 10 close to the brush head 20, and a limiting ring 12 is movably sleeved on the outer wall of the brush handle 10 located in the groove 11. The limiting ring 12 slides along the direction of the brush head 20 and is movably sleeved with the replacement head 30 and one end of the brush head 20 to form a limiting structure.

[0036] When the replacement head 30 is disassembled, the stop ring 12 which is sleeved at one end of the replacement head 30 and the brush head 20 overlaps is slid into the groove 11 so that the stop ring 12 remains in the groove 11 and is not easy to fall off.

[0037] Then lift up the replacement head 30 and separate it, and clip the new replacement head 30 onto the brush head 20, then slide the limiting ring 12 to the overlapping position of the replacement head 30 and the brush head 20 for sleeve fixation, which is beneficial to enhance the fixation of the replacement head 30 and enhance the stability of the installation.

[0038] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
