Technical Field

[0001] This utility model relates to the field of daily necessities, specifically a toothpick holder and a device for replacing toothpicks. Background Technology

[0002] Toothpicks are a common item for cleaning the mouth. They are an auxiliary tool used in conjunction with toothbrushes in daily oral care. One end of a toothpick is pointed and can be used to pick up food residue between teeth. They are widely used in daily life. Traditional toothpicks are discarded after use, which wastes resources to some extent.

[0003] CN205569106U provides a toothpick with replaceable tips, including a toothpick tip 1, an elastic collar 2, and a toothpick handle 3. In use, one end of the toothpick handle 3 and the fine tip of the toothpick tip 1 are respectively inserted into the through holes at both ends of the elastic collar 2. The elastic collar 2 tightly connects the toothpick handle 3 and the toothpick tip 1 together. When it is necessary to replace the toothpick tip, simply remove the old toothpick tip and replace it with a new one.

[0004] The replaceable toothpicks provided by the existing technology have a toothpick tip that easily rotates after being inserted into the elastic sleeve, and cannot effectively remove food residue from between teeth during use. Utility Model Content

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] Example 1

[0035] like Figure 1-2 As shown, the present invention provides a replaceable toothpick device, including a toothpick 1, a fixing sleeve 2, an elastic ring 3 and a handle 4. The fixing sleeve 2 is sleeved on the upper part of the handle 4 and can move up and down along the handle 4.

[0036] like Figure 3 As shown, the toothpick 1 includes a toothpick head 11 and a toothpick handle 12. The toothpick head 11 is curved and has a pointed tip to facilitate the removal of food residue from between the teeth. To stably fix the toothpick handle 12 to the handle 4, the toothpick handle 12 is flat and has grooves 13 on both sides. The bottom of the toothpick handle 12 is rounded.

[0037] Furthermore, such as Figure 5 As shown, an opening 44 is provided at the upper part of the handle 4, the bottom of the opening 44 is an arc-shaped groove 42, and protrusions 43 are provided on both sides of the opening 44. An annular groove 41 is also provided in the handle 4, which is located below the opening 44. A step 45 is also provided at the top of the handle 4, which is located above the opening 44.

[0038] The toothpick handle 12 can be inserted into the opening 44. When the toothpick handle 12 is inserted into the opening 44, the protrusion 43 on the handle 4 is engaged in the groove 13, and the bottom of the toothpick handle 12 is engaged with the arc groove 42. At this time, the fixing sleeve 2 is moved up so that the fixing sleeve 2 is fitted on the upper part of the handle 4 to fix the toothpick handle 12 in the opening 44. The fixing sleeve 2 makes the two side walls of the opening 44 close and fasten the toothpick handle 12.

[0039] The flat toothpick handle 12 fits against the two side walls of the opening 44 to prevent the toothpick 1 from rotating. At the same time, the protrusion 43 is inserted into the groove 13, and the bottom of the toothpick handle 12 is engaged with the arc-shaped groove 42 to axially position the toothpick 1 and prevent the toothpick 1 from coming out of the opening 44.

[0040] like Figure 4 As shown, a through hole is provided inside the fixing sleeve 2, and a positioning hole 21 is provided at the top of the through hole. The diameter of the positioning hole 21 is larger than that of the through hole. A fixing groove 22 is provided at the bottom of the through hole. The fixing groove 22 is an R-shaped groove.

[0041] Furthermore, after the fixing sleeve 2 slides upward to fix the toothpick handle 12, in order to prevent the fixing sleeve 2 from sliding downward, an annular groove 41 is also provided on the handle 4, and an elastic ring 3 is fitted in the annular groove 41. When the fixing sleeve 2 slides upward to the position where the toothpick handle 12 is fixed, the elastic ring 3 is engaged in the fixing groove 22, and the spring ring 3 limits the up and down movement of the fixing sleeve 2. At the same time, the fixing groove 22 is set as an R-shaped groove, so that when it is necessary to replace the toothpick, it is convenient to slide the fixing sleeve 2 downward to separate the toothpick 1 from the handle 4.

[0042] Furthermore, by creating a step 45 at the top of the handle 4, when the fixing sleeve 2 slides upward, the step 45 engages with the positioning hole 21, preventing the fixing sleeve 2 from continuing to slide upward. The step 45 prevents the fixing sleeve 2 from continuing to slide upward and dislodging from the handle 4.

[0043] Furthermore, to prevent the toothpick 1 from slipping out of the opening 44, a protrusion 43 and a groove 13 are provided to cooperate. Both the protrusion 43 and the groove 13 are square. In addition, the protrusion 43 and the groove 13 can also be arc-shaped, polygonal, or other shapes.

[0044] Furthermore, both the toothpick 1 and the handle 4 are made of non-metallic materials, such as plastic, silicone, and other elastic materials.

[0045] Working principle

[0046] When toothpick 1 needs to be installed, slide the retaining sleeve 2 downwards from the handle 4, opening the opening 44 at the top of the handle 4. Then, insert the toothpick handle 12 into the opening 44, with the bottom of the handle 12 engaging with the arc-shaped groove 42. Next, push the retaining sleeve 2 upwards to close the opening 44, with the flat toothpick handle 12 fitting against the two side walls of the opening 44. The protrusion 43 on the handle 4 engages in the groove 13. Continue moving the retaining sleeve 2 upwards until the step 45 engages in the positioning hole 21, and the elastic ring 3 engages in the retaining groove 22. Due to the action of the elastic ring 3, the retaining sleeve 2 will not move automatically upwards or downwards, completing the installation and fixation of toothpick 1. When toothpick 1 needs to be removed, push the retaining sleeve 2 downwards forcefully, causing the elastic ring 3 to dislodge from the retaining groove 22, opening the opening 44. At this point, toothpick 1 can be easily pulled out.

[0047] Example 2

[0048] Unlike Embodiment 1, in order to prevent the toothpick 1 from slipping out of the opening 44, a first protrusion is provided on both sides of the toothpick handle 12. Correspondingly, a first groove is provided on both sides of the opening 44. When the toothpick handle 12 is inserted into the opening 44, the first protrusion is inserted into the first groove. Both the first protrusion and the first groove are square. In addition, the first protrusion and the first groove can also be arc-shaped, polygonal, or other shapes.
