Description

Technical Field

[0001] This utility model relates to the field of electric toothbrushes, and in particular to a copper-free, non-coated electric toothbrush head. Background Technology

[0002] As people pay increasing attention to oral hygiene, electric toothbrushes are becoming more and more popular in daily life. However, traditional electric toothbrush heads are gradually revealing many shortcomings in design and function, making it difficult to meet the increasingly diverse needs of consumers and higher hygiene standards.

[0003] Regarding the bristle fixing, early electric toothbrush heads mostly used simple embedding or adhesive methods to fix the bristles, which lacked stability. During brushing, the bristles are prone to loosening and falling off due to repeated friction and torsional forces, which not only affects the brushing effect, but the detached bristles may also remain in the mouth, posing potential health risks.

[0004] Waterproofing is also a crucial factor. Since toothbrushes are typically in a damp environment after use, moisture can easily seep into the brush head through gaps and pores. If this water cannot drain away promptly, the brush head will remain damp for an extended period, becoming a breeding ground for bacteria and causing problems such as odor and mold, seriously harming oral health. While common electric toothbrush heads have some waterproof design features, they are often inadequate and fail to provide comprehensive waterproofing and moisture protection.

[0005] Furthermore, the complexity and stability of the installation process also hinder the industry's development. During the assembly of some toothbrush heads, due to unreasonable installation structure design, the connection between the brush plates is not firm, and gaps and glue overflow are prone to occur during ultrasonic welding. This not only affects the product's appearance quality, but also reduces the product's reliability and durability, and increases production costs and the defect rate.

[0006] Therefore, it is necessary to provide a new type of copper-free coated electric toothbrush head to solve the above-mentioned technical problems. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a copper-free coated electric toothbrush head.

[0008] This utility model provides a copper-free, rubber-coated electric toothbrush head with a cover, comprising: a brush handle, one end of which is provided with a brush plate, the brush plate having a brush blade mounting position connected to the brush blade plate, and the brush plate being covered with soft rubber; and a cover and protective mechanism, which includes a welded layer located on the lower side of the brush blade plate, and a protruding layer located at the top edge of the brush blade plate.

[0009] Preferably, the flaking layer is applied to the surface of the soft rubber, and the flaking layer is located at the upper end of the joint.

[0010] Preferably, the back of the soft gel has a streamlined design, and a radial tongue scraper is provided on the soft gel.

[0011] Preferably, the brush plate has a brush mounting position, and the brush tray is fixedly installed in the brush mounting position.

[0012] Preferably, a plurality of ultrasonic lines are provided at the bottom of the brush mounting position, the plurality of ultrasonic lines are arranged in a ring, an ultrasonic cavity is formed between the plurality of ultrasonic lines, the plurality of ultrasonic lines are designed to be continuously disconnected, and an overflow groove is provided on the side of the plurality of ultrasonic lines.

[0013] Preferably, the width of the drift layer is greater than the width of the ultrasonic cavity, and the width of the drift layer is less than the width of the brush plate.

[0014] Preferably, a plurality of welding adhesive pillars are provided on the back side of the brush plate, and the plurality of welding adhesive pillars are connected to the welding layer.

[0015] Preferably, the back side of the brush plate is provided with reinforcing ribs, and each of the two side walls of the brush plate is provided with symmetrical slots. The brush plate is provided with a soft rubber mounting position, and the soft rubber is fixedly installed in the soft rubber mounting position.

[0016] Compared with related technologies, the copper-free coated electric toothbrush head provided by this utility model has the following beneficial effects:

[0017] 1. This utility model uses the design of the fusion layer to form a sealed cavity inside the brush plate, which effectively prevents water from entering the cavity through the pores, keeps the cavity dry, and is not easy to breed bacteria. The floating layer is pressed tightly onto the soft rubber surface after ultrasonic installation to form a sealed waterproof layer, preventing water from seeping into the brush plate from the joint. The double waterproof protection greatly reduces the risk of bacterial growth caused by moisture, extends the hygienic service life of the toothbrush head, and protects the oral health of users.

[0018] 2. This utility model uses a hot-melt method to fuse the bristle tip with multiple welding adhesive pillars to form a fusion layer, and the fusion layer is further fused with multiple welding adhesive pillars, so that the bristles are firmly fixed to the brush plate, preventing the bristles from easily falling off or shifting during brushing, ensuring the stability and durability of the brushing effect. The brush plate tray rests on the fusion layer, providing additional support for the bristles, making them more firmly fixed, effectively improving the durability of the toothbrush head. Even under greater external force, the bristles are not easy to be concave or deformed inward, and always maintain a good cleaning state.

[0019] 3. This utility model ingeniously improves the installation tolerance of the brush plate by utilizing the design of the floating layer, effectively improving the problem of glue overflow caused by ultrasonic welding. This not only reduces the difficulty of production and installation and improves production efficiency, but also ensures the consistency and stability of product quality and reduces the defect rate. In addition, the bottom of the brush plate mounting position is provided with a ring of continuously discontinuous ultrasonic lines, which facilitates the discharge of glue overflow during welding. At the same time, a glue overflow groove is provided next to the ultrasonic lines, which can efficiently collect the glue overflow generated during ultrasonic welding, improve the welding effect, make the brush plate installed more firmly, and further enhance the stability of the entire toothbrush head structure.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Please refer to the following: Figures 1 to 6A copper-free coated electric toothbrush head includes: a handle 1, a brush plate at one end of the handle 1, a brush plate tray 11 at the brush plate, a brush plate 2 at the upper side of the brush plate tray 11, a plurality of pores 21 on the brush plate 2, bristles 3 installed and connected in each of the plurality of pores 21, and a soft rubber 4 covering the outside of the brush plate; a protective cover mechanism, including a welded layer 5, the welded layer 5 being located at the lower side of the brush plate 2, a protruding layer 51 at the top edge of the brush plate 2, and a joint seam 52 between the brush plate 2 and the soft rubber 4.

[0029] In the specific implementation process, such as Figure 1 and Figure 2 As shown, the protruding layer 51 is pressed onto the surface of the soft rubber 4, and the protruding layer 51 is located at the upper end of the joint 52.

[0030] It should be noted that: multiple adhesive columns 7 are located next to multiple pores 21 on the brush plate 2. The ends of the brush bristles 3 inside the multiple pores 21 are fused together with the multiple adhesive columns 7 by heat fusion to form a fusion layer 5, thereby fixing the brush bristles 3 on the fusion layer 5. The fusion layer 5 is then fused together with the multiple adhesive columns 7, so the brush bristles 3 are fixed on the brush plate 2 to form an assembly.

[0031] At the same time, the welded layer 5 is fixed at one end of multiple pores 21, so that a sealed cavity is formed inside the brush plate 2, and water can no longer enter the inner cavity through the pores 21, keeping the cavity dry and preventing bacteria from growing.

[0032] After ultrasonic installation, the protruding layer 51 at the top of the brush plate 2 is pressed tightly onto the surface of the soft rubber 4, forming a sealed and waterproof structure. Water cannot enter the interior of the brush plate 2 from the joint 52, keeping the interior dry and preventing the growth of bacteria.

[0033] The protruding layer 51 is located at the upper end of the brush plate 2 and the joint 52, and just covers the joint 52. The design of the protruding layer 51 makes the installation tolerance of the brush plate 2 higher and effectively improves the problem of glue overflow caused by ultrasonication.

[0034] The width of the floating layer 51 can be any size between 0.2 and 1.0.

[0035] refer to Figure 1 As shown, the back of the soft gel 4 has a streamlined design, and there are 10 radial tongue scrapers 41 on the soft gel 4.

[0036] It should be noted that the back of the soft rubber 4 has a streamlined design and is equipped with 10 radial tongue scrapers 41 for cleaning tongue coating and dirt.

[0037] refer to Figure 1 and Figure 2As shown, the brush plate is provided with a brush plate mounting position 6, and the brush plate tray 11 is fixedly installed in the brush plate mounting position 6.

[0038] It should be noted that the brush plate tray 11 is located in the brush plate mounting position 6 and rests against the welding layer 5, which makes the brush bristles 3 more secure, improves durability, and prevents the brush bristles 3 from being deformed inward under force.

[0039] refer to Figure 1 As shown, multiple ultrasonic lines 61 are provided at the bottom of the brush mounting position 6. The multiple ultrasonic lines 61 are arranged in a ring and form an ultrasonic cavity between them. The multiple ultrasonic lines 61 are designed to be continuously disconnected. An overflow groove 62 is provided on the side of the multiple ultrasonic lines 61.

[0040] It should be noted that: the brush plate mounting position 6 on the front of the brush plate is used to install the brush plate 2. A ring of ultrasonic wires 61 is provided at the bottom of the brush plate mounting position 6 for ultrasonically fixing the brush plate 2. The ultrasonic wires 61 are designed to be continuously discontinuous, which is conducive to the discharge of welding excess glue. An excess glue groove 62 is provided next to the ultrasonic wires 61 at a distance of 0.1 mm. The excess glue groove 62 is used to collect the excess glue generated during ultrasonication, which improves the welding effect and makes the connection firm.

[0041] After ultrasonic welding, the installation of the brush plate 2 can be firmly guaranteed, and it can also serve as a second layer of waterproofing.

[0042] The glue overflow tank 62 is equipped with a brush tray 11.

[0043] refer to Figure 1 and Figure 6 As shown, the width of the drift layer 51 is greater than the width of the ultrasonic cavity, and the width of the drift layer 51 is less than the width of the brush plate.

[0044] refer to Figure 1 and Figure 3 As shown, multiple welding adhesive pillars 7 are provided on the back side of the brush plate 2, and the multiple welding adhesive pillars 7 are connected to the welding layer 5.

[0045] It should be noted that one end of the brush bristle 3 is fused to the adhesive column 7 to form a fusion layer 5, thereby fixing the brush bristle 3 to the fusion layer 5.

[0046] refer to Figure 1 and Figure 3 As shown, the back of the brush plate is provided with reinforcing ribs 8, and the two side walls of the brush plate are symmetrically provided with slots 81. The brush plate is provided with soft rubber mounting positions 82, and the soft rubber 4 is fixedly installed in the soft rubber mounting positions 82.

[0047] It should be noted that there are 4 latches 81 on both sides of the brush plate. The latches 81 can hold the soft rubber 4 tightly, making the connection more secure.

[0048] The back of the brush plate is provided with reinforcing ribs 8. The function of reinforcing ribs 8 is to strengthen the brush plate and prevent it from becoming too soft and deformed.

[0049] The brush handle head is covered with soft rubber 4, which is fixed to the outside of the brush head by two-color injection molding to form a closed-loop pattern. The soft rubber 4 can reduce the stimulation of the oral cavity caused by the vibration of the back of the brush handle, and achieve a shock-absorbing effect.

[0050] The working principle of the copper-free coated electric toothbrush head provided by this utility model is as follows: The ends of the bristles 3 are fused to multiple adhesive posts 7 located on the brush plate 2 through a hot-melt process. The numerous adhesive posts 7 are interconnected and fused with the bristles 3 to form a stable fusion layer 5, so that the bristles 3 can be tightly and firmly attached to the brush plate 2. This multi-welded structure ensures that the bristles 3 can remain in place during brushing, regardless of friction or pressure from all directions, and will not easily loosen, fall off, or shift.

[0051] The welded layer 5 is fixed to one end of the pore 21, sealing the internal pores of the brush plate 2 and creating a physical barrier. This effectively prevents water from seeping into the internal cavity of the brush plate 2 through the pores 21, avoiding bacterial growth due to water accumulation and ensuring a consistently dry internal environment. After ultrasonic installation, the protruding layer 51 at the top of the brush plate 2 is tightly pressed against the surface of the soft adhesive 4, sealing the joint 52 and completely eliminating the possibility of external moisture seeping into the brush plate 2. This provides double waterproof protection and greatly extends the hygienic lifespan of the toothbrush head.

[0052] Under ultrasonic action, the annular ultrasonic line 61 at the bottom of the brush mount 6 ensures a tight fit between the brush plate 2 and the brush plate, achieving initial fixation. The ultrasonic line 61 features a continuously discontinuous design, allowing excess adhesive to drain smoothly during ultrasonic welding, preventing adhesive buildup and ensuring a better weld. Simultaneously, the overflow groove 62 adjacent to the ultrasonic line 61 precisely collects any excess adhesive, further optimizing the weld quality and ensuring a more secure connection between the brush plate 2 and the brush plate. The brush tray 11, installed in the brush mount 6 and abutting against the weld layer 5, provides additional support to the bristles 3 from below. Working in conjunction with ultrasonic fixation, it strengthens the fixation of the bristles 3, effectively preventing them from deforming inwards during brushing and ensuring smooth brushing.

[0053] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
