Description

Technical Field

[0001] This application relates to the technical field of cleaning supplies, and in particular to a toothbrush for reducing the movement of the toothbrush bristle heads and its production process. Background Art

[0002] A toothbrush is a cleaning supply, a handle-type brush, used to apply toothpaste on the brush and then repeatedly brush various parts of the teeth to maintain oral hygiene.

[0003] When producing a toothbrush, the toothbrush body is first formed by injection molding. The body includes a brush handle and a brush head. The brush handle is for the user to hold. Multiple receiving grooves for receiving bristles are formed on the brush head. During production, a bunch of bristles are planted into the receiving grooves by a bristle-planting device. The bristles are fixed by the groove walls of the receiving grooves squeezing the bristle heads of the bristles. At this time, the brush head forms a cleaning side and can be used to apply toothpaste for oral cleaning. After bristle-planting, a trimming device is used to trim and polish the side of the bristles away from the bristle heads, so that the length of the bristles meets the design requirements, and at the same time, the sharpness of the bristles is removed to improve the softness of the bristles.

[0004] In the process of implementing this application, the inventor found that at least the following problems exist in this technology: during oral cleaning, the bristles swing back and forth, which may drive the movement of the bristle heads of the bristles, resulting in relative sliding between the bristle heads and the groove walls of the receiving grooves, causing the bristle heads to break away from the receiving grooves and resulting in the toothbrush shedding bristles. Summary of the Invention

[0005] In order to reduce the possibility of the bristle heads of the bristles moving, this application provides a toothbrush for reducing the movement of the toothbrush bristle heads and its production process.

[0006] In a first aspect, this application provides a toothbrush for reducing the movement of the toothbrush bristle heads, adopting the following technical solution:

[0007] A toothbrush for reducing the movement of the toothbrush bristle heads includes a brush handle and a bristle bundle. One end of the brush handle in the extending direction is provided with a brush head. An installation groove is formed at one end of the brush head facing away from the cleaning side. A plurality of through holes for the bristle bundle to pass through are formed on the groove wall of the installation groove away from the groove opening. The brush head is provided with installation blocks corresponding to the through holes one by one. The bristle heads of the bristle bundle are fixed to the installation blocks. A connection groove communicating with the through holes and for placing the installation blocks is formed on the groove wall of the installation groove away from the groove opening. The brush head is provided with a detachable fixing plate for restricting the movement of the installation blocks in the direction of the groove opening of the installation groove.

[0008] By adopting the above technical solution, the bristle heads of the bristles are fixed on the installation blocks. After installation, the installation blocks are restricted by the groove walls of the connection groove and the fixing plate, so that the installation blocks are in a fixed state. During use, the bristle heads of the bristles are fixed, and at the same time, the installation blocks are restricted, reducing the possibility of the bristle heads of the bristles moving when the bristles swing.

[0009] Optionally, a clamping block is provided on the outer peripheral side of the fixing plate, and a clamping groove for the clamping block to be inserted into is formed on the peripheral groove wall of the installation groove.

[0010] By adopting the above technical solution, when in use, the clamping block is inserted into the clamping groove, the fixing of the fixing plate can be realized, and the fixing plate can be disassembled and removed when needed.

[0011] Optionally, the connecting groove penetrates to the outside of the brush head toward the side away from the notch of the installation groove. A limiting groove surrounding and communicating with the connecting groove is formed on the groove wall of the installation groove on the side away from the notch. The brush head is hingedly provided with a limiting plate located in the limiting groove and capable of flipping toward or away from the installation groove. There are at least three limiting plates and they are arranged along the central axis of the through hole evenly in a surrounding manner.

[0012] By adopting the above technical solution, when replacing the brush hair bundle, the installation block can be passed through the through hole and the connecting groove on the cleaning side of the brush head, without passing the brush hair bundle through the through hole, which is beneficial to reducing the difficulty of replacing the brush hair bundle.

[0013] Optionally, the limiting plate includes a connecting plate and an extrusion plate. The connecting plate is hingedly connected to the brush head. The extrusion plate is hinged to the side of the connecting plate close to the through hole. The extrusion plate is provided with a supporting block for supporting the installation block, and the fixing plate is provided with a pressing block for pressing the installation block toward the side away from the notch of the installation groove.

[0014] By adopting the above technical solution, after the fixing plate is fixed, the pressing block presses the installation block, so that the extrusion plate flips to drive the supporting block to follow and flip, so that the supporting block presses the brush hair, improving the fixing strength of the brush hair. At the same time, the extrusion plate abuts against the installation block, improving the installation stability of the installation block.

[0015] Optionally, the connecting plate is provided with a rubber block. When the connecting plate abuts against the groove wall of the limiting groove on the side away from the installation groove, the extrusion plate abuts against the side of the rubber block close to the installation groove.

[0016] By adopting the above technical solution, during use, the elasticity of the rubber block is released, which can support the extrusion plate. At the same time, the rubber block can undergo elastic deformation when the extrusion plate flips.

[0017] Optionally, the side of the supporting block away from the extrusion plate is of an arc-shaped concave surface structure.

[0018] By adopting the above technical solution, during use, the contact area between the supporting block and the brush hair bundle is increased through the arc-shaped concave surface structure.

[0019] Optionally, the distance between the side of the supporting block away from the extrusion plate and the central axis of the brush hair bundle is less than the radius of the brush hair bundle.

[0020] By adopting the above technical solution, when in use, the support block presses the bristle bundle, which is beneficial to improving the fixing strength of the bristle bundle.

[0021] In a second aspect, the present application provides a production process for a toothbrush, adopting the following technical solution:

[0022] A production process for a toothbrush, used to produce a toothbrush that reduces the movement of the toothbrush head, is characterized by including the following steps:

[0023] Step 1: Form the toothbrush handle and the toothbrush head by injection molding;

[0024] Step 2: Fix the bristle bundle to the mounting block by hot melting;

[0025] Step 3: Install the bristle bundle on the toothbrush head and fix the mounting block through the fixing plate;

[0026] Step 4: Trim and polish the side of the bristle bundle away from the mounting block;

[0027] Step 5: Inspect and package the finished toothbrush.

[0028] By adopting the above technical solution, during production, the bristle bundle is fixed on the mounting block, and then the fixing block is connected and fixed to the toothbrush head, which is beneficial to reducing the possibility of the toothbrush head of the bristles moving. At the same time, the bristle bundle can be replaced when needed, reducing waste of resources.

[0029] In summary, the present application includes at least one of the following beneficial effects:

[0030] 1. The toothbrush head of the bristles is fixed on the mounting block, and at the same time, the mounting block is restricted by the groove wall of the connecting groove and the fixing plate, reducing the possibility of the toothbrush head of the bristles moving;

[0031] 2. When replacing the bristle bundle, the mounting block can be passed through the connecting groove and the through hole from the cleaning side of the toothbrush head and then enter the mounting groove, and then the bristle bundle is pulled in the direction away from the groove wall of the mounting groove.

Detailed implementation manners

[0042] The following Figures 1-9 further describes the present application in detail.

[0043] The embodiment of the present application discloses a toothbrush for reducing the movement of the toothbrush head.

[0044] Embodiment 1:

[0045] Referring to Figure 1 , the toothbrush for reducing the movement of the toothbrush head includes a brush handle 1 and a bristle bundle 2.

[0046] See Figure 2 And Figure 3, one end of the brush handle 1 in the extending direction is fixedly connected with a brush head 3, and one end of the brush head 3 is provided with a mounting groove 31, and a plurality of through holes 32 are provided on the groove wall of the mounting groove 31 on the side away from the groove, for the bristle bundle 2 to pass through, so that the bristle bundle 2 cooperates to form a cleaning side, and toothpaste can be added to clean teeth. The brush head 3 is provided with a mounting block 21 of a round block structure, and there are multiple mounting blocks 21 and they correspond to the through holes 32 one by one, and the bristle bundle 2 is fixed to one end of the mounting block 21 by a hot melt process. A connecting groove 33 is provided on the groove wall of the mounting groove 31 on the side away from the groove, and the connecting groove 33 surrounds the through hole 32 and is connected to the through hole 32. During installation, the bristle bundle 2 passes through the through hole 32, and the mounting block 21 is placed in the connecting groove 33 at the same time, and the mounting block 21 is limited by the groove wall of the connecting groove 33 to reduce the possibility of sliding, and the diameter of the mounting block 21 is larger than the diameter of the through hole 32. The brush head 3 is provided with a fixing plate 4, which is installed in the mounting groove 31 during use to fix the mounting block 21, thereby reducing the possibility of the mounting block 21 moving toward the notch of the mounting groove 31, thereby reducing the possibility of the bristles of the brush moving.

[0047] See also Figure 2 Since the bristle bundle 2 can be removed along with the mounting block 21, the mounting block 21 with the bristle bundle 2 fixed thereon can be produced separately during production. When the bristle bundle 2 on the brush head 3 needs to be replaced, only the bristle bundle 2 and the mounting block 21 need to be replaced, without replacing the brush handle 1 and the brush head 3, which is conducive to reducing resource waste.

[0048] See also Figure 5 and Figure 6 In other embodiments, the connecting groove 33 and the through hole 32 can also be opened on the fixing plate 4. During installation, the bristle bundle 2 is first passed through the through hole 32 until the mounting block 21 abuts against the wall of the connecting groove 33. Then, after the fixing plate 4 and the brush head 3 are fixed, the groove wall of the mounting groove 31 away from the groove opening is pressed against the mounting block 21 to reduce the movement of the bristle bundle 2.

[0049] See also Figure 2 and Figure 3, a plurality of clamping blocks 41 are fixedly arranged on the outer peripheral side of the fixing plate 4 at uniform intervals, and corresponding clamping grooves 311 are communicated and opened on the peripheral side wall of the installation groove 31. The clamping grooves 311 are located at positions close to the notch of the installation groove 31. The clamping blocks 41 are made of elastic plastic structures. During use, the clamping blocks 41 are clamped into the clamping grooves 311, so that the fixing plate 4 is fixed. At this time, one side of the installation block 21 facing the notch of the installation groove 31 abuts against the fixing plate 4. A taking-out port is opened on one side of the fixing plate 4 away from the installation groove 31. The taking-out port is located at the edge of the fixing plate 4. When the brush hair bundle 2 needs to be replaced, the fixing plate 4 can be buckled out through the taking-out port, which is convenient for replacing the brush hair bundle 2. In other embodiments, the clamping blocks 41 can also be in the form of clamping rings. During production, the clamping rings are wound around the outer peripheral side of the fixing plate. Correspondingly, the clamping grooves 311 are formed in the form of matching annular clamping grooves. During installation, the fixing plate is fixed by clamping the clamping rings in the annular clamping grooves.

[0050] The implementation principle of a toothbrush for reducing the movement of the toothbrush head in the first embodiment of the present application is as follows:

[0051] During production, the brush hairs are arranged in bundles, and the hair heads of the brush hairs are fixed to one end of the installation block 21 by hot melting. During installation, the installation block 21 is placed on the connecting groove 33, and then the fixing plate 4 is fixed in the installation groove 31. At this time, the installation block 21 abuts against the fixing plate 4, so that the installation block 21 is fixed, reducing the possibility that the brush hair heads drive the brush hair bundles to move when cleaning the oral cavity.

[0052] Embodiment Two:

[0053] See Figure 2 And Figure 3 , the brush hair bundle 2 fixed on the installation block 21 needs to be trimmed and polished after production, so the side of the brush hair bundle 2 away from the installation block 21 is relatively scattered. When the brush hair bundles 2 on the brush head 3 are regularly replaced, in order to facilitate the installation of the brush hair bundles 2 through the through holes 32, an improved optimization scheme is proposed in the present application on the basis of the first embodiment.

[0054] See Figure 6 And Figure 7 , the connecting groove 33 penetrates through to the outside of the brush head 3 on the side away from the notch of the installation groove 31. At this time, the installation block 21 can enter the installation groove 31 from the side of the brush head 3 away from the installation groove 31 through the connecting groove 33 and the through hole 32, reducing the installation difficulty of the installation block 21.

[0055] See Figure 7 And Figure 8 , a plurality of limiting grooves 34 are opened on the groove wall on the side of the installation groove 31 away from the notch. The limiting grooves 34 surround the connecting groove 33 and correspond to each other one by one. The limiting grooves 34 are communicated with the connecting groove 33. The brush head 3 is provided with a limiting plate 5. There are at least three limiting plates 5 and they are evenly spaced along the circumferential direction with the central axis of the through hole 32 as the center of the circle.

[0056] See Figure 8 and Figure 9 , the limiting plate 5 includes a connecting plate 51 and a pressing plate 52. The connecting plate 51 and the pressing plate 52 are respectively rectangular plate structures. The connecting plate 51 is hinged in the limiting groove 34 through a shaft. During use, the connecting plate 51 can be flipped towards or away from the mounting groove 31. When the connecting plate 51 is flipped to the horizontal state, the connecting plate 51 abuts against the groove wall on the side of the limiting groove 34 away from the mounting groove 31. One side wall in the width direction of the pressing plate 52 is fixedly provided with a hinge block 521. One side in the width direction of the connecting plate 51 is provided with a hinge groove 511. Hinge shafts are respectively fixedly connected to the opposite side walls of the hinge block 521, and the hinge shafts are hinged on the groove wall of the hinge groove 511.

[0057] See Figure 7 and Figure 8 , when the connecting plate 51 and the pressing plate 52 are in the horizontal state, the length direction of the connecting plate 51 and the length direction of the pressing plate 52 are on the same straight line. A rubber block 54 is fixedly connected to the groove wall on the side of the connecting plate 51 away from the mounting groove 31. The rubber block 54 is made of rubber material with a certain elasticity. A relief groove is provided on the groove wall on the side of the limiting groove 34 away from the mounting groove 31 for accommodating the rubber block 54, so that the connecting plate 51 can abut against the groove wall of the limiting groove 34. The rubber block 54 is located at a position close to the pressing plate 52 and extends into the connecting groove 33. When the side of the pressing plate 52 abutting against the side away from the mounting groove 31 abuts against the rubber block 54, the pressing plate 52 and the connecting plate 51 are in the same plane. At this time, the distance between the side of the pressing plate 52 away from the connecting plate 51 and the central axis of the brush bundle 2 is greater than the radius of the brush bundle 2.

[0058] See Figure 7 and Figure 8 , a support block 53 with a rectangular cross-section is fixedly connected to the side of the pressing plate 52 away from the rubber block 54, and the support block 53 is located at a position away from the pressing plate 52, so that the length direction of the support block 53 is perpendicular to the length direction of the pressing plate 52. One end of the support block 53 away from the pressing plate 52 is an arc concave surface side structure. When the mounting block 21 passes through the connecting groove 33 and the through hole 32 from the cleaning side of the brush head 3 and enters the mounting groove 31, the mounting block 21 pushes the connecting plate 51 and the pressing plate 52 to flip towards the mounting groove 31. After the mounting block 21 enters the mounting groove 31, the brush bundle 2 is pulled downward. At this time, the side wall on the side of the mounting block 21 away from the notch of the mounting groove 31 abuts against the arc concave surface side of the support block 53 until the connecting plate 51 abuts against the groove wall on the side of the limiting groove 34 away from the mounting groove 31 and stops. At this time, the pressing plate 52 abuts against the rubber block 54.

[0059] See Figure 7 and Figure 8, on the side of the fixing plate 4 facing the through hole 32, a plurality of abutting blocks 42 are fixedly connected. The shapes and sizes of the abutting blocks 42 are adapted to and correspond one by one to the limiting grooves 34. When the fixing plate 4 is fixed, the abutting blocks 42 squeeze the mounting block 21 towards the cleaning side of the brush head 3 until the abutting blocks 42 abut against the side wall of the connecting plate 51 close to the mounting groove 31. At this time, the pressing plate 52 flips to a state where its length direction is parallel to the central axis of the through hole 32. At this time, the rubber block 54 follows the pressing plate 52 to flip and abuts against the peripheral groove wall of the connecting groove 33, and the outer peripheral side of the mounting block 21 abuts against the pressing plate 52. When the pressing plate 52 flips, the supporting block 53 follows the flip until the length direction of the pressing plate 52 is parallel to the central axis of the through hole 32, and the length direction of the supporting block 53 is parallel to the length direction of the connecting plate 51. The distance between the arc concave side of the supporting block 53 and the central axis of the bristle bundle 2 is less than the radius of the bristle bundle 2. When the supporting blocks 53 flip, they cooperate with each other to squeeze the bristle bundle 2 towards the central axis direction of the bristle bundle 2, improving the fixing strength of the bristles and further reducing the possibility of the bristle tips moving.

[0060] The implementation principle of a toothbrush for reducing the movement of toothbrush bristle tips in the second embodiment of the present application is as follows:

[0061] When the bristle bundle 2 needs to be replaced, remove the fixing plate 4 by disassembly, and then push the bristle bundle 2 towards the notch of the mounting groove 31, so that the mounting block 21 is separated from the mounting groove 31, and at the same time drive the old bristle bundle 2 to be separated from the brush head 3. When replacing the new bristle bundle 2, pass the mounting block 21 of the bristle bundle 2 through the connecting groove 33 and the through hole 32 from the cleaning side of the brush head 3 into the mounting groove 31. After the mounting block 21 enters the mounting groove 31, pull the bristle bundle 2 in the direction away from the notch of the mounting groove 31, so that the connecting plate 51 abuts against the side wall of the limiting groove 34 far from the mounting groove 31, and then fix the fixing plate 4. When the fixing plate 4 is fixed, it squeezes the mounting block 21, so that the mounting block 21 drives the pressing plate 52 to flip until the length direction of the pressing plate 52 is parallel to the central axis of the through hole 32, realizing the fixing of the bristle bundle 2. The whole process is simple and can reduce the replacement difficulty of the bristle bundle 2.

[0062] The present application also discloses a production process of a toothbrush for producing a toothbrush for reducing the movement of toothbrush bristle tips, including the following steps:

[0063] Step 1: Form the brush handle 1 and the brush head 3 by injection molding;

[0064] Step 2: Fix the bristle bundle 2 to the mounting block 21 by hot melting;

[0065] Step 3: Install the bristle bundle 2 on the brush head 3 and fix the mounting block 21 through the fixing plate 4;

[0066] Step 4: Trim and polish the side of the bristle bundle 2 away from the mounting block 21;

[0067] Step Five: Inspect and package the finished toothbrushes.

[0068] The above are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
