Description

Technical Field

[0001] This utility model relates to the field of toiletries technology, and in particular to a folding toothbrush with a bidirectional limiting and protective structure. Background Technology

[0002] A folding toothbrush is a toothbrush with a foldable handle. Existing folding toothbrushes include a front handle and a rear handle. The front handle has bristles, and the rear handle can rotate and fold or unfold relative to the front handle. When unfolded, the rear handle is in use; when folded, it is in a stored state. Because the rear handle can rotate relative to the front handle, it is easy for it to accidentally close (fold) during use when unfolded, or to accidentally open (unfold) during storage when folded. Utility Model Content

[0003] The purpose of this invention is to provide a folding toothbrush with a bidirectional limiting and protective structure to solve the problem of instability in the unfolded and folded states of existing folding toothbrushes.

[0004] This utility model is achieved through the following technical solution:

[0005] A folding toothbrush with a bidirectional limiting and protective structure includes a front handle and a rear handle. One of the front handle and the rear handle is provided with a pivot that is rotatably connected to the other. The rear handle rotates and folds or unfolds relative to the front handle around the pivot axis. A folding damping block and an unfolding damping block are protruding on the outer periphery of the rear handle. The folding damping block and the unfolding damping block are arc-shaped protrusions. The unfolding damping block is eccentrically disposed with respect to the pivot axis. When the rear handle is unfolded, the unfolding damping block abuts against the front handle, restricting the rear handle from rotating in the folding direction. When the rear handle is folded, the folding damping block abuts against the front handle, restricting the rear handle from rotating in the unfolding direction.

[0006] Furthermore, the front handle has a damping ramp that extends forward at an angle from bottom to top. When the rear handle is unfolded, the damping ramp abuts against the unfolding damping block to restrict the rear handle from rotating in the folding direction. When the rear handle is folded, the damping ramp abuts against the folding damping block to restrict the rear handle from rotating in the unfolding direction.

[0007] Furthermore, the front handle is provided with a limiting block, and the rear handle is provided with a folding limiting groove and an unfolding limiting groove. When the rear handle is folded, the folding limiting groove engages with the limiting block to restrict the rotation of the rear handle, and the unfolding limiting groove engages with the limiting block to restrict the rotation of the rear handle when the rear handle is unfolded.

[0008] Furthermore, the folding damping block is disposed on one side of the folding limiting groove, and the thickness of the protrusion gradually decreases in the direction away from the folding limiting groove.

[0009] Furthermore, the deployment damping block is disposed on one side of the deployment limiting groove, and the thickness of the protrusion gradually decreases in the direction away from the deployment limiting groove.

[0010] Furthermore, the rear handle has a connector, the front handle has a receiving groove for accommodating the connector, and the connector is provided with the rotating shaft, the folding damping block and the unfolding damping block.

[0011] Furthermore, the connector is cylindrical and coaxially arranged with the rotating shaft.

[0012] Furthermore, the upper side of the front handle is provided with bristles, and the upper side of the rear handle is provided with a receiving cavity. When the rear handle is folded, the bristles are housed in the receiving cavity and spaced apart from the bottom of the receiving cavity. The folding damping block abuts against the front handle when the rear handle is folded, restricting the rear handle from continuing to rotate in the folding direction.

[0013] Furthermore, the bottom of the receiving cavity is provided with several vent holes.

[0014] The advantage of this technical solution is that by configuring a folding damping block and an unfolding damping block on the outer periphery of the rear handle, and configuring the folding damping block and the unfolding damping block as arc protrusions eccentrically set with the pivot, the unfolding damping block can cooperate with the front handle to restrict the rear handle from rotating in the folding direction when the rear handle is unfolded. At the same time, the folding damping block can cooperate with the front handle to restrict the rear handle from rotating in the unfolding direction when the rear handle is folded. This allows the folding toothbrush with a bidirectional limiting and protective structure to have a stable unfolded state and a folded state, resulting in a better user experience.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example: Figure 1-10As shown, the folding toothbrush with a bidirectional limiting and protective structure includes a front handle 1 and a rear handle 2. One of the front handle 1 and the rear handle 2 is provided with a rotating shaft 201 that is rotatably connected to the other. The rear handle 2 rotates and folds or unfolds relative to the front handle 1 around the axis of the rotating shaft 201. A folding damping block 202 and an unfolding damping block 203 are protruding on the outer periphery of the rear handle 2. The folding damping block 202 and the unfolding damping block 203 are arc-shaped protrusions. The unfolding damping block 203 is eccentrically set with the rotating shaft 201. When the rear handle 2 is unfolded, the unfolding damping block 203 abuts against the front handle 1 to restrict the rear handle 2 from rotating in the folding direction. The folding damping block 202 is eccentrically set with the rotating shaft 201. When the rear handle 2 is folded, the folding damping block 202 abuts against the front handle 1 to restrict the rear handle 2 from rotating in the unfolding direction. The unfolding damping block 203 is eccentrically set with respect to the rotating shaft 201, meaning that the axis of the cylinder containing the unfolding damping block 203 is offset from the axis of the rotating shaft 201. The folding damping block 202 is eccentrically set with respect to the rotating shaft 201, meaning that the axis of the cylinder containing the folding damping block 202 is offset from the axis of the rotating shaft 201.

[0029] Specifically, when the rear handle 2 is unfolded, the state of the folding toothbrush with the bidirectional limiting protection structure is defined as the unfolded state; when the rear handle 2 is folded, the state of the folding toothbrush with the bidirectional limiting protection structure is defined as the folded state.

[0030] like Figures 1 to 3 As shown, in the unfolded state, the rear handle 2 unfolds, and the unfolding damping block 203 abuts against the front handle 1 and cooperates with the front handle 1 to restrict the rear handle 2 from rotating in the folding direction, so that the unfolded state of the folding toothbrush with bidirectional limiting protection structure is stable.

[0031] like Figures 4 to 6 As shown, in the folded state, the rear handle 2 is folded onto the front handle 1, and the folding damping block 202 abuts against the front handle 1 and cooperates with the front handle 1 to restrict the rear handle 2 from rotating in the unfolding direction, so that the folding state of the folding toothbrush with bidirectional limiting protection structure is stable.

[0032] In summary, this embodiment provides a folding toothbrush with a bidirectional limiting and protective structure to solve the problem of unstable unfolded and folded states in existing folding toothbrushes. This is mainly achieved by configuring a folding damping block 202 and an unfolding damping block 203 on the outer periphery of the rear handle 2. The folding damping block 202 and the unfolding damping block 203 are configured as arc-shaped protrusions eccentrically positioned relative to the pivot 201. This allows the unfolding damping block 203 to cooperate with the front handle 1 to restrict the rear handle 2 from rotating in the folding direction when it is unfolded, and simultaneously allows the folding damping block 202 to cooperate with the front handle 1 to restrict the rear handle 2 from rotating in the unfolding direction when it is folded. This results in a stable unfolded and folded state for the folding toothbrush, providing a superior user experience.

[0033] Specifically, the rear handle 2 is folded when rotated counterclockwise and unfolded when rotated clockwise. The thickness of the protrusion of the folding damping block 202 gradually increases in the counterclockwise direction, and the thickness of the protrusion of the unfolding damping block 203 gradually increases in the counterclockwise direction.

[0034] In this embodiment of the invention, the front handle 1 has a damping ramp 101, which extends forward and downward from bottom to top. When the rear handle 2 is unfolded, the damping ramp 101 abuts against the unfolding damping block 203, restricting the rear handle 2 from rotating in the folding direction; when the rear handle 2 is folded, the damping ramp 101 abuts against the folding damping block 202, restricting the rear handle 2 from rotating in the unfolding direction. This arrangement, by configuring a damping ramp 101 that extends forward and downward from bottom to top on the front handle 1, and by using the damping ramp 101 to abut against and restrict the rotation of the rear handle 2 with the unfolding damping block 203 or the folding damping block 202, ensures that the folding toothbrush with a bidirectional limiting and protective structure has a stable unfolded and folded state.

[0035] In this embodiment of the invention, a limiting block 102 is provided on the front handle 1, and a folding limiting groove 204 and an unfolding limiting groove 205 are provided on the rear handle 2. When the rear handle 2 is folded, the folding limiting groove 204 engages with the limiting block 102 to restrict the rotation of the rear handle 2. When the rear handle 2 is unfolded, the unfolding limiting groove 205 engages with the limiting block 102 to restrict the rotation of the rear handle 2. This arrangement, by configuring the limiting block 102 on the front handle 1 and the folding limiting groove 204 and unfolding limiting groove 205 on the rear handle 2, allows the limiting block 102 to engage with either the folding limiting groove 204 or the unfolding limiting groove 205 to restrict the rotation of the rear handle 2, thus ensuring that the folding toothbrush with a bidirectional limiting and protective structure has a stable unfolded and folded state.

[0036] In this embodiment of the invention, the folding damping block 202 is disposed on one side of the folding limiting groove 204. When the rear handle 2 is folded, the folding damping block 202 is located in front of the folding limiting groove 204, and the thickness of the protrusion gradually decreases in the direction away from the folding limiting groove 204. This arrangement, by placing the folding damping block 202 on one side of the folding limiting groove 204 and having the thickness of the protrusion gradually decrease in the direction away from the folding limiting groove 204, gives the folding damping block 202 a good damping and limiting effect.

[0037] In this embodiment of the invention, the unfolding damping block 203 is disposed on one side of the unfolding limiting groove 205. When the rear handle 2 unfolds, the unfolding damping block 203 is located in front of the unfolding limiting groove 205, and its protrusion thickness gradually decreases in the direction away from the unfolding limiting groove 205. This arrangement, by placing the unfolding damping block 203 on one side of the limiting groove and ensuring its protrusion thickness gradually decreases in the direction away from the unfolding limiting groove 205, provides the unfolding damping block 203 with a good damping and limiting effect.

[0038] In this embodiment of the invention, the rear handle 2 has a connector 206, and the front handle 1 has a receiving groove 103 for accommodating the connector 206. The connector 206 is provided with a rotating shaft 201, a folding damping block 202, and an unfolding damping block 203, which are located on the outer periphery of the connector 206. This arrangement ensures stable assembly and smooth rotation of the rear handle 2 and the front handle 1.

[0039] Specifically, there are two rotating shafts 201, which are located on the left and right sides of the connector 206 and are coaxially arranged. The front handle 1 has two rotating shaft holes (not shown in the figure), which are inserted into the two rotating shafts 201. The rear handle 2 is detachably fixed to the front handle 1 through the two rotating shafts 201. Because the rear handle 2 is detachably fixed to the front handle 1 through the two rotating shafts 201, the rear handle 2 and the front handle 1 can be quickly assembled and disassembled.

[0040] In this embodiment of the invention, the connector 206 is cylindrical and coaxially arranged with the rotating shaft 201. This arrangement, by configuring the connector 206 as a cylinder and coaxially arranged with the rotating shaft 201, ensures smooth rotation of the rear handle 2 and provides excellent damping and limiting effects from the folding damping block 202 and the unfolding damping block 203.

[0041] In this embodiment of the invention, the upper side of the front handle 1 is provided with bristles 3, and the upper side of the rear handle 2 is provided with a receiving cavity 207. When the rear handle 2 is folded, the bristles 3 are housed in the receiving cavity 207 and spaced apart from the bottom of the receiving cavity 207. The folding damping block 202 abuts against the front handle 1 when the rear handle 2 is folded, restricting the rear handle 2 from continuing to rotate in the folding direction. The above arrangement, by configuring the receiving cavity 207 on the rear handle 2 to house the bristles 3 when the rear handle 2 is folded, avoids contamination of the bristles 3. At the same time, since the bottom of the receiving cavity 207 is spaced apart from the bristles 3 when the rear handle 2 is folded, and the folding damping block 202 abuts against the front handle 1 when the rear handle 2 is folded, restricting the rear handle 2 from continuing to rotate in the folding direction, the bristles 3 are prevented from contacting the bottom of the receiving cavity 207 and being damaged.

[0042] In this embodiment of the invention, the bottom of the receiving cavity 207 is provided with a plurality of vent holes 208. The above-mentioned arrangement, by providing a plurality of vent holes 208 at the bottom of the receiving cavity 207, prevents moisture from accumulating in the receiving cavity 207 and the brush bristles 3.
