Description

Technical Field

[0001] This invention relates to the field of dental floss picks, and particularly to a dental floss pick with an adjustable angle. Background Technology

[0002] Dental floss picks, also known as floss picks, are oral care tools used in conjunction with toothbrushes. Before the widespread use of dental floss picks, people relied on toothpicks for cleaning. Compared to traditional toothpicks, dental floss picks stand out due to their convenience, efficiency, safety, and hygiene.

[0003] There are various types of dental floss picks on the market, which can be divided into manual and electric types according to their drive mechanism; and into one-piece and two-piece types according to their structure. Two-piece dental floss picks usually consist of a handle and a floss holder, with the floss holder being a replaceable part. One-piece dental floss picks are often discarded after their usage period due to floss wear and bacterial growth, which not only increases the user's financial burden but also leads to resource waste. Two-piece dental floss picks allow for replacement of the floss holder, thus saving users' usage costs; however, the connection between the floss holder and handle in traditional two-piece dental floss picks is unreliable or the connection method is too complicated. In addition, the angle between the floss holder and the handle is fixed, making it difficult to clean individual gaps between teeth, which is not very convenient to use. Summary of the Invention

[0004] This invention provides an adjustable-angle dental floss pick, which solves the problem in the prior art where the angle of the dental floss holder and handle is fixed, making it difficult to clean individual gaps between teeth and causing inconvenience in use.

[0005] The present invention provides the following solution to the above-mentioned technical problems: An adjustable-angle dental floss pick includes: a dental floss head, a fixing sleeve, and a handle. The fixing sleeve includes a positioning post and a clamping head arranged sequentially from top to bottom. The positioning post is rotatably connected to the handle, and the clamping head clamps and fixes the dental floss head. The positioning post passes through the front end of the handle and is connected to a clamping member. The clamping member presses the front end of the handle against the upper surface of the clamping head. The front end of the handle is located between the clamping head and the clamping member. The upper surface of the clamping head is flat, and the upper surface of the clamping head forms a contact friction force with the front end of the handle. The clamping head includes a first clamping plate and a second clamping plate. A clamping groove is formed between the first clamping plate and the second clamping plate, and the dental floss head is inserted into the clamping groove.

[0006] Preferably, the clamping component engages with the upper part of the positioning post. The clamping component includes a ring and a protrusion. The protrusion is located on the inner side of the ring. The upper part of the positioning post has a second groove. The ring is fitted around the outer periphery of the positioning post, and the protrusion is engaged in the second groove. Preferably, multiple protrusions are provided, and the multiple protrusions are evenly distributed on the inner side of the ring. The second groove is arranged around the outer periphery of the positioning post and is annular.

[0007] Preferably, the dental floss head includes a floss holder and a floss body. The floss holder is U-shaped, and the floss body connects the two ends of the floss holder. The floss holder is detachably installed in a clamping groove.

[0008] Preferably, protrusions are provided on both sides of the dental floss holder, and snap-fit ​​grooves are provided on the inner sides of the first clamping plate and the second clamping plate; the protrusions on both sides engage with the snap-fit ​​grooves at the corresponding positions.

[0009] Preferably, a groove is provided on the top of the dental floss holder, and a protrusion is provided on the top of the clamping groove, with the protrusion engaging with the groove at the corresponding position.

[0010] Preferably, all three grooves—groove one, groove two, and snap-fit ​​groove—are circular arc grooves.

[0011] Preferably, the handle includes a rod body, a connecting ring at the front end of the rod body, a folding rod rotatably connected to the rear end of the rod body, a positioning pin rotatably connected to the connecting ring, and a contact friction force formed between the lower surface of the connecting ring and the upper surface of the clamping head.

[0012] Preferably, a positioning port and a rotating pin are provided at the rear end of the rod. The folding rod has a U-shaped groove structure. A connecting hole is provided on both sides of the front end of the folding rod, and a stop strip is provided between the two connecting holes. The rotating pin is inserted into the connecting hole, and the front end of the stop strip can be engaged in the positioning port.

[0013] Preferably, the front end of the stop strip is bent towards the positioning opening, and the stop strip is elastic.

[0014] The beneficial effects of this invention are as follows: This invention provides an adjustable-angle dental floss pick, which has the following advantages:

[0015] 1. The handle and the fixed sleeve are rotatably connected. The handle can be adjusted 360 degrees. The positioning pin of the fixed sleeve passes through the connecting ring of the handle, and the protrusion of the clamping part is inserted into the second groove. The clamping part pulls the positioning pin upward to make the connecting ring fit tightly against the positioning surface of the fixed sleeve. A large contact friction force is formed between the connecting ring and the positioning surface, so that the handle can stop rotating at any angle, providing a convenient angle adjustment method.

[0016] 2. The dental floss holder is detachably installed in the fixed sleeve. The clamping head of the fixed sleeve includes a first clamping plate and a second clamping plate. When the dental floss head is inserted into the clamping groove formed between the first clamping plate and the second clamping plate, the protrusions on both sides of the dental floss holder slide into the snap-fit ​​groove. The protrusion at the top of the clamping groove snaps into the groove at the top of the dental floss holder. Under the elastic force of the first clamping plate and the second clamping plate, the dental floss head is firmly clamped in the fixed sleeve. The cooperation between the protrusion and the groove prevents the dental floss head from shifting laterally in the clamping groove.

[0037] Example

[0038] like Figure 1 As shown, the present invention provides an adjustable angle dental floss pick, including a dental floss head 1, a fixing sleeve 2 and a handle 3. The handle 3 is rotatably connected to the fixing sleeve 2, and the handle 3 fixes the dental floss head 1 through the fixing sleeve 2.

[0039] like Figure 2As shown, the dental floss head 1 includes a dental floss holder 12 and a floss body 11. The floss body 11 has a fineness of 200 denier, allowing the user to easily press the dental floss 6 into the gaps between teeth. The dental floss holder 12 is U-shaped, and the floss body 11 connects the two ends of the dental floss holder 12. The dental floss holder 12 can be detachably installed in the fixing sleeve 2 for easy replacement.

[0040] like Figure 3-4 As shown, the fixing sleeve 2 includes a positioning post 21 and a clamping head 22, which are arranged sequentially from top to bottom. The positioning post 21 is rotatably connected to the handle 3, and the clamping head 22 clamps and fixes the dental floss head 1. The positioning post 21 passes through the front end of the handle 3 and is connected to the clamping member 4. The clamping member 4 presses the front end of the handle 3 against the upper surface of the clamping head 22. The front end of the handle 3 is located between the clamping head 22 and the clamping member 4. The upper surface of the clamping head 22 is a plane, and the upper surface of the clamping head 22 forms a contact friction force with the front end of the handle 3.

[0041] The positioning post 21 is positioned above the clamping head 22. The clamping head 22 includes a positioning surface 221, a first clamping plate 222, and a second clamping plate 223. A clamping groove 224 is formed between the first clamping plate 222 and the second clamping plate 223. The dental floss head 1 is inserted into the clamping groove 224, and the dental floss holder 12 is detachably installed in the clamping groove 224. The positioning surface 221 is a plane and is positioned at the top of the clamping head 22. The positioning post 21 is connected to the positioning surface 221.

[0042] When the fixed sleeve 2 is connected to the handle 3, the positioning pin 21 passes through the front end of the handle 3 and connects to the clamping member 4. Then, the clamping head 22 and the clamping member 4 clamp and press the front end of the handle 3. The clamping member 4 applies downward pressure to the front end of the handle 3, so that the front end of the handle 3 is tightly attached to the positioning surface 221. The clamping element 4 and the positioning pin 21 can be connected by various methods such as threaded connection, plug-in connection, or snap-fit ​​connection. When the clamping element 4 and the positioning pin 21 are threaded, a wing nut is used as the clamping element 4, and an external thread is provided on the upper part of the positioning pin 21. After the positioning pin 21 passes through the front end of the handle 3, the front end of the handle 3 is pressed against the upper surface of the clamping head 22 by tightening the wing nut. When the connection method between the clamping element 4 and the positioning pin 21 is set to plug-in, a pin is used as the clamping element 4, and a positioning hole is provided on the upper part of the positioning pin 21. After the positioning pin 21 passes through the front end of the handle 3, the pin is inserted into the positioning hole, and the front end of the handle 3 is pressed against the upper surface of the clamping head 22 under the force of the pin.

[0043] When the clamping member 4 and the positioning post 21 are engaged, a second groove 211 is provided on the upper part of the positioning post 21. The second groove 211 is arranged around the outer periphery of the positioning post 21 and is annular. Figure 5As shown, the clamping member 4 includes a ring body 41 and a protrusion 42. The protrusion 42 is disposed on the inner side of the ring body 41. The ring body 41 is sleeved on the outer periphery of the positioning post 21, and the protrusion 42 is engaged in the groove 211, thereby preventing the ring body 41 from moving up and down in the axial direction of the positioning post 21.

[0044] like Figure 6 As shown, the handle 3 includes a connecting ring 31, a rod 32, and a folding rod 33. The connecting ring 31 is located at the front end of the rod 32, and the folding rod 33 is rotatably connected to the rear end of the rod 32. When the handle 3 is connected to the fixing sleeve 2, the positioning pin 21 passes through the connecting ring 31. A clamping member 4 is connected above the positioning pin 21. When the clamping member 4 is connected to the positioning pin 21, the protrusion 42 engages in the groove 211 on the upper part of the positioning pin 21. The clamping member 4 pulls the positioning pin 21 upwards, applying downward pressure to the connecting ring 31, causing the connecting ring 31 to adhere tightly to the positioning surface 221. The connecting ring 31 and the positioning pin 21 are rotatably connected, allowing the handle 3 to be adjusted 360 degrees. Simultaneously, under the clamping force of the clamping member 4 and the fixing sleeve 2, the connecting ring 31 and the positioning surface 221 have a large contact area, resulting in significant friction. This allows the handle 3 to stop rotating at any angle (e.g., ...). Figure 9-10 As shown in the image, the angle adjustment method is convenient.

[0045] Furthermore, in order to improve the uniformity of force distribution between the protrusion 42 and the second groove, the second groove 211 is set as an annular shape and arranged along the circumference of the positioning post 21. Multiple protrusions 42 are provided, and the multiple protrusions 42 are evenly distributed on the inner side of the annular body 41.

[0046] To facilitate the installation of the dental floss holder 12 within the fixing sleeve 2, furthermore, protrusions 121 are provided on both sides of the dental floss holder 12, with the protrusions 121 on both sides arranged symmetrically; a groove 122 is provided on the top of the dental floss holder 12; correspondingly, snap-fit ​​grooves 225 are provided on the inner sides of both the first clamping plate 222 and the second clamping plate 223; the protrusions 121 on both sides respectively engage with the snap-fit ​​grooves 225 at the corresponding positions; the fixing sleeve 2 is made of an elastic material, such as plastic; the first clamping plate 222 and the second clamping plate 223... The second clamping plate 223 is elastic. When the dental floss head 1 is inserted into the fixing sleeve 2, the protrusion 121 slides into the snap-fit ​​groove 225. Under the elastic force of the first clamping plate 222 and the second clamping plate 223, the dental floss head 1 is firmly clamped in the fixing sleeve 2. In addition, a protrusion 226 is provided on the top of the clamping groove 224. The protrusion 226 engages with the corresponding groove 122. Through the engagement of the protrusion 226 and the groove 122, the dental floss head 1 is prevented from shifting laterally in the clamping groove 224.

[0047] Furthermore, the groove 122, the groove 211, and the snap-fit ​​groove 225 can be configured with various shapes, such as U-shaped grooves, arc grooves, etc.

[0048] like Figure 7-8 As shown, a folding rod 33 is rotatably connected to the rear end of the rod body 32. A positioning port 321 and a rotating pin 322 are provided at the rear end of the rod body 32. A rotating pin 322 is provided on each side of the rod body 32, and a positioning port 321 is provided between the two rotating pins 322. The folding rod 33 has a U-shaped groove structure, and the rod body 32 is rotatably connected in the U-shaped groove of the folding rod 33. A connecting hole 332 is provided on each of the two side walls of the front end of the folding rod 33, and a stop strip 331 is provided between the two connecting holes 332.

[0049] When the rod body 32 is connected to the folding rod 33, the rotating pin 322 is inserted into the connecting hole 332, and the folding rod 33 is rotatably connected to the rod body 32. In order to limit the rotation angle of the folding rod 33, a stop strip 331 and a positioning port 321 are provided. When the folding rod 33 is fully opened, that is, when the folding rod 33 and the rod body 32 are collinear, the front end of the stop strip 331 can be inserted into the positioning port 321, thereby preventing the folding rod 33 from rotating further upward. Furthermore, the front end of the stop strip 331 bends towards the positioning port 321. The stop strip 331 is elastic, so during the opening process of the folding rod 33, the front end of the stop strip 331 continues to contact the end of the rod body 32. When the folding rod 33 is fully opened, a "click" collision sound is made, and the front end of the stop strip 331 falls completely into the positioning port 321. The folding rod 33 is designed to facilitate the storage of dental floss picks and improve the convenience of use.

[0050] Working principle

[0051] First, install the dental floss head 2. Press the dental floss head 2 upward along the opening of the clamping groove 43, and align the position of the groove 122 with the protrusion 226. Press the dental floss head 2 into the clamping groove 43. At this time, the two protrusions 122 are respectively engaged in the two engagement grooves 225, and the protrusion 226 is engaged in the groove 122. The dental floss head 2 is fixed in the clamping groove 43 by the clamping force of the first clamping plate 222 and the second clamping plate 223, thus completing the installation.

[0052] Then, open the folding lever 33. When a "click" sound is heard, it indicates that the front end of the stop bar 331 has completely fallen into the positioning slot 321, and the folding lever 33 is fully open; rotate the handle 3 to adjust the angle between the handle 3 and the dental floss head 2 (e.g., Figure 9-10 As shown), by utilizing the contact friction between the connecting ring 31 and the positioning surface 221, the handle 3 can be stopped at any angle and no longer rotated, so that the dental floss head 2 is aligned with the corresponding gap, and then the gap is cleaned.

[0053] Finally, after cleaning, apply downward force from both sides of the floss holder 12 to make the protrusion 122 cut out the snap-fit ​​groove 225, separating the floss head 2 from the fixing sleeve 2, and detach the floss head 2 from the handle 3; fold the handle, rotate it back to its original position, and put away the floss pick.
