Description

Technical Field

[0001] This invention relates to the field of animal brushing and cleaning technology, specifically to a replaceable dental cleaning pen. Background Technology

[0002] Because early symptoms of periodontal disease such as bleeding gums, swollen and painful gums, and tartar are often overlooked, public awareness of oral health is weak, and care methods are outdated. Often, treatment is only sought when teeth become loose, fall out, or become painful. Currently, there is a lack of home oral care products specifically for periodontal health on the market, and these products are difficult to carry around and cannot offer a one-stop solution with multiple functional heads.

[0003] Traditional dental curettes typically consist of a handle and a scraper head. The scraper head is usually a sharp, curved shape used to scrape away substances inside the mouth. When cleaning the mouth, the scraper head needs to be carefully inserted into the area that needs cleaning, and then gently scraped to remove plaque, food debris, or other deposits from the tooth surface. Traditional curettes are complicated to use, and dental care personnel need to be professionally trained to use them. Furthermore, improper operation can easily injure the gums. There are many types of curettes, and when changing to a curette with different functions, the curette in use needs to be removed and a new one installed, which is inconvenient.

[0004] Therefore, we propose a replaceable oral cleaning pen to address the problems mentioned above. Summary of the Invention

[0009] Preferably, one end of the fixing rod is fixedly connected to an installation sleeve, and the inner wall of the installation sleeve is movably connected to a connecting assembly. The connecting assembly includes a connecting body, one end of the connecting body is fixedly connected to a threaded sleeve, the outer surface of the threaded sleeve is threadedly connected to the inner wall of the installation sleeve, the connecting body has a placement groove inside, the pull handle is placed inside the placement groove, one end of the threaded sleeve is provided with a limiting spring, one end of the limiting spring is fixedly connected to a limiting top ring, and the outer surface of the limiting top ring is in contact with the outer surface of the hollow semi-cylinder.

[0010] Preferably, a connecting sleeve is fixedly connected to the other end of the connector, and a chip fixing slot is provided at one end of the connecting sleeve, with a chip reader disposed inside the chip fixing slot.

[0011] Preferably, a limiting ring is fixedly sleeved on the outer surface of the connector, and a plurality of hemispherical blocks are fixedly connected to the outer surface of the connector away from the threaded sleeve along the circumferential direction. A pen cap is movably sleeved on the outside of the connector, and a slot is opened on the inner wall of the pen cap near one end. The outer surfaces of the plurality of hemispherical blocks are engaged with the inner wall of the slot.

[0012] Preferably, a mounting clip is fixedly connected to the outer surface of the pen cap near the other end, and a reinforcing arc clip is fixedly connected to the inner wall of one side of the mounting clip.

[0013] Preferably, the connecting sleeve is externally movably connected to a positioning component, the positioning component including a connector, one end of the connector having a connecting groove, the inner wall of the connecting groove being threadedly connected to the outer surface of the connecting sleeve, and the other end of the connector having a T-shaped hole.

[0014] Preferably, a protective frame is fixedly connected to the outer surface of the rubber gear, and a protective sponge is pasted on the inner wall of the protective frame. Positioning grooves are opened on both outer surfaces of the rubber gear, and positioning rings are fixedly connected to both outer surfaces of the semi-circular rubber gear ring. The opposite sides of the two positioning rings are rotatably connected to the inner walls of the two positioning grooves respectively.

[0015] Preferably, one of the locking blocks and the reinforcing rod is movably installed inside the T-shaped hole, and the other two locking blocks are respectively movably engaged inside the two slots.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. When using the scraper assembly, first remove the pen cap, then rotate the connector and connector body in sequence. Pull the pull handle outwards to remove the assembly. Then, by turning the rubber gear, the rubber gear rotates under the limit of the two positioning rings. The rubber gear and the semi-circular rubber toothed ring act as dampers to prevent the rubber gear from rotating too freely. This allows the scraper assembly to be replaced to be rotated to the opening of the hollow semi-cylinder. This makes it easy to take out the scraper assembly and prevents it from falling out when the pull-out assembly is pulled out. Users can replace it as needed, and it can meet the needs of different scenarios. It solves the problems of inconvenience in carrying and limited functionality. In addition, the protective sponge protects the marking chip installed on the surface of the card block from being scratched and damaged.

[0017] 2. When using the dental cleaning pen, the locking block of one of the scraper components to be used needs to be installed in the T-shaped hole. By rotating the connector and fitting it onto the outside of the connecting sleeve, the installation of the connector and the connecting body is completed. At this time, the chip reader corresponds to the corresponding marking chip. The chip reader reads the contents of the marking chip to identify the category of the corresponding scraper head. The information recorded inside the three marking chips is different, recording the categories of the three scraper heads respectively. The result read by the chip reader is transmitted to the controller, which controls the display panel to display the category of the scraper head. Thus, without opening the pen cap, it is possible to know which scraper component is currently installed, which has the advantages of portability and easy identification.

[0018] 3. During use, the threaded sleeve is connected to the mounting sleeve. During the connection process, the pull handle will be slowly inserted into the placement groove. At the same time, the limiting top ring contacts the second circular block, and the limiting spring continuously contracts. Its elasticity can compress the pull assembly, making the installation of the pull assembly inside the inner groove more stable and preventing the teeth cleaning pen from shaking during use. Then, the pen cap is put on. When the slot engages with the hemispherical block, the limiting ring can block the pen cap, fixing the installation position of the pen cap. The pen cap can effectively protect the scraper assembly installed on the connector, thus making it easy to carry. Attached Figure Description

[0022] Please see Figure 1-10 This invention provides a technical solution: a replaceable oral cleaning pen, comprising: a pen barrel assembly 1, which includes a fixing rod 101, the fixing rod 101 having an inner recess 102; a pull-out assembly 2, which is movably installed inside the inner recess 102, the pull-out assembly 2 including a hollow semi-cylinder 202, one end of which is fixedly connected to a first circular block 201, the other end of which is fixedly connected to a second circular block 203, and a pull handle 204 fixedly connected to the outer surface of the second circular block 203; and a replacement assembly 6, which includes... The device includes a semi-circular rubber toothed ring 603, with a rubber gear 605 meshing with the inner wall of the semi-circular rubber toothed ring 603, and two slots 607 formed on the outer surface of the rubber gear 605; a scraper assembly 12, of which three scraper assemblies are provided, each scraper assembly 12 including a locking block 1201, a marking chip 1205 on one side of each locking block 1201, a reinforcing rod 1202 fixedly connected to the other side of each locking block 1201, a scraper handle 1203 fixedly connected to one end of each reinforcing rod 1202, and a scraper head 1204 fixedly connected to one end of each scraper handle 1203.

[0023] like Figure 9 As shown, a first mounting slot 106 is provided at one end of the recessed slot 102, and a second mounting slot 103 is provided at one end of the first mounting slot 106. A movable battery 107 is disposed inside the first mounting slot 106, and a controller 104 is disposed inside the second mounting slot 103. A spacer block 105 is fixedly installed at one end of the first mounting slot 106. The controller 104 is installed inside the second mounting slot 103. The spacer block 105 is installed on the inner wall of the first mounting slot 106 near the second mounting slot 103 by using a screwdriver and screws, so that the position of the controller 104 is stable and will not shake during use.

[0024] like Figure 1 , Figure 2 and Figure 9As shown, the inner wall of the first mounting groove 106 is provided with a connection port 108, and a protective block 10 is movably connected to the inner wall of the connection port 108. A display panel 9 is provided on the outer surface of the fixing rod 101. The protective block 10 is pressed and snapped into the interior of the connection port 108 to prevent the movable battery 107 from falling out during use. The controller 104 controls the display panel 9 to display the type of the scraper head 1204.

[0025] like Figure 4 , Figure 5 and Figure 6 As shown, one end of the fixing rod 101 is fixedly connected to the mounting sleeve 11, and the inner wall of the mounting sleeve 11 is movably connected to the connecting assembly 3. The connecting assembly 3 includes a connecting body 301, one end of the connecting body 301 is fixedly connected to a threaded sleeve 302, the outer surface of the threaded sleeve 302 is threadedly connected to the inner wall of the mounting sleeve 11, the connecting body 301 has a placement groove 308 inside, the pull handle 204 is placed inside the placement groove 308, one end of the threaded sleeve 302 is provided with a limiting spring 309, and one end of the limiting spring 309 is fixedly connected to a limiting top ring 3. 10. The outer surface of the limiting top ring 310 contacts the outer surface of the hollow semi-cylinder 202. By connecting the threaded sleeve 302 to the mounting sleeve 11, the pull handle 204 will be slowly inserted into the placement groove 308 during the connection process. At the same time, the limiting top ring 310 contacts the second circular block 203, and the limiting spring 309 continuously contracts. Its elastic function can squeeze the pull assembly 2, making the installation of the pull assembly 2 inside the inner groove 102 more stable and preventing the tooth cleaning pen from shaking inside during use.

[0026] like Figure 4 , Figure 5 and Figure 6 As shown, a connecting sleeve 305 is fixedly connected to the other end of the connector 301. A chip fixing slot 307 is provided at one end of the connecting sleeve 305. A chip card reader 306 is installed inside the chip fixing slot 307, thereby enabling the installation of the chip card reader 306.

[0027] like Figure 4 , Figure 5 and Figure 6 As shown, a limiting ring 303 is fixedly sleeved on the outer surface of the connector 301. Multiple hemispherical blocks 304 are fixedly connected to the outer surface of the connector 301 away from the threaded sleeve 302 along the circumferential direction. A pen cap 5 is movably sleeved on the outside of the connector 301. A slot 13 is opened on the inner wall of the pen cap 5 near one end. The outer surfaces of the multiple hemispherical blocks 304 are engaged with the inner wall of the slot 13. When the slot 13 is engaged with the hemispherical blocks 304, the limiting ring 303 can block the pen cap 5 by covering it with the pen cap 5, so that the installation position of the pen cap 5 is fixed. The pen cap 5 can effectively protect the scraper assembly 12 installed on the connector 401, thus having the advantage of being easy to carry.

[0028] like Figure 1 As shown, a mounting clip 7 is fixedly connected to the outer surface of the pen cap 5 near the other end. A reinforcing arc clip 8 is fixedly connected to the inner wall of one side of the mounting clip 7. The mounting clip 7 can clip the pen cap 5 to a book or clothing pocket to prevent loss, while the reinforcing arc clip 8 can make the dental pen clamp more tightly.

[0029] like Figure 4 , Figure 5 and Figure 6 As shown, a positioning component 4 is movably connected to the outside of the connecting sleeve 305. The positioning component 4 includes a connector 401. One end of the connector 401 has a connecting groove 402. The inner wall of the connecting groove 402 is threadedly connected to the outer surface of the connecting sleeve 305. The other end of the connector 401 has a T-shaped hole 403. By rotating the connector 401 and fitting it onto the outside of the connecting sleeve 305, the installation of the connector 401 and the connecting body 301 is completed.

[0030] like Figure 3 , Figure 5 , Figure 7 , Figure 8 and Figure 10 As shown, a protective frame 601 is fixedly connected to the outer surface of the rubber gear 605. A protective sponge 602 is pasted on the inner wall of the protective frame 601. Positioning grooves 606 are opened on both outer surfaces of the rubber gear 605. Positioning rings 604 are fixedly connected to both outer surfaces of the semi-circular rubber tooth ring 603. The opposite sides of the two positioning rings 604 are rotatably connected to the inner walls of the two positioning grooves 606 respectively. The protective sponge 602 protects the marking chip 1205 installed on the surface of the card block 1201 from being scratched and damaged. By moving the rubber gear 605, the rubber gear 605 rotates under the limit of the two positioning rings 604. Since the rubber gear 605 and the semi-circular rubber tooth ring 603 are both made of rubber material, they mesh with each other when rotating, but will not be completely jammed. They play a damping role with each other to prevent the rubber gear 605 from rotating too flexibly.

[0031] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 10 As shown, one of the locking blocks 1201 and the reinforcing rod 1202 are movably installed inside the T-shaped hole 403, and the other two locking blocks 1201 are respectively movably engaged inside the two slots 607. The scraper handle 1203 is passed through the T-shaped hole 403 and the locking blocks 1201 and the reinforcing rod 1202 are engaged inside the T-shaped hole 403. The two spare scraper assemblies 12 are placed inside the hollow semi-cylinder 202 and the locking blocks 1201 are inserted into the slots 607.

[0032] The usage method and working principle of this device are as follows: First, install the controller 104 into the second mounting slot 103. Then, using a screwdriver and screws, install the spacer 105 onto the inner wall of the first mounting slot 106 near the second mounting slot 103 to ensure the controller 104 is stably installed and will not wobble during use. Next, pull out the protective block 10 and install the mobile battery 107 into the first mounting slot 106. The installation structure and method of the mobile battery 107 are the same as existing installation methods. Then, press the protective block 10 into the connector 108 to prevent the mobile battery 107 from falling out during use. The controller 104, chip card reader 306, and display panel 9 are all connected to... The mobile batteries 107 are electrically connected and powered by each other. The controller 104 has a pre-programmed module that controls the display panel 9 and the chip card reader 306. Since there are three types of scraper heads 1204, each is different, with different functions: an anterior tooth hook, a posterior tooth hook, and an interdental brush. When assembling the dental cleaning pen, the locking block 1201 of one of the scraper components 12 to be used needs to be installed in the T-hole 403. During installation, the scraper head 1204 is inserted from the end near the connecting groove 402 until the scraper handle 1203 passes through the T-hole 403 and the locking block 1201 and reinforcing rod 1202 are engaged within the T-hole 403. The connection is then closed. The connector 401 is rotated and fitted onto the outside of the connecting sleeve 305, completing the installation of the connector 401 and the connector 301. At this time, the chip reader 306 corresponds to the corresponding marking chip 1205. The chip reader 306 reads the contents of the marking chip 1205 to identify the category of the corresponding scraper head 1204. The information recorded inside the three marking chips 1205 is different, recording the categories of the three scraper heads 1204 respectively. The result read by the chip reader 306 is transmitted to the controller 104, which controls the display panel 9 to display the category of the scraper head 1204. Thus, without opening the pen cap 5, it is possible to know which scraper component 12 is currently installed, which is portable and easy to use. The advantage of this design is that the other two spare scraper components 12 are placed inside the hollow semi-cylinder 202. The locking block 1201 is inserted into the slot 607, and the threaded sleeve 302 is connected to the mounting sleeve 11. During the connection process, the pull handle 204 will slowly be inserted into the placement slot 308. At the same time, the limiting top ring 310 contacts the second circular block 203, and the limiting spring 309 continuously contracts. Its elastic function can compress the pull-out component 2, making the installation of the pull-out component 2 inside the inner groove 102 more stable and preventing the teeth cleaning pen from shaking during use. Then, the pen cap 5 is put on. When the locking groove 13 engages with the hemispherical block 304, the limiting ring 303 can block the pen cap 5, fixing the installation position of the pen cap 5.The pen cap 5 effectively protects the scraper assembly 12 mounted on the connector 401, thus providing portability. When the scraper assembly 12 needs to be replaced, first remove the pen cap 5, then rotate the connector 401 and the connector body 301 in sequence to remove the scraper assembly 12 mounted on the connector 401. By pulling the pull handle 204 outward, the pull assembly 2 can be pulled out from the inner groove 102. After being pulled out, by turning the rubber gear 605, the rubber gear 605 rotates under the limit of the two positioning rings 604. Since both the rubber gear 605 and the semi-circular rubber toothed ring 603 are... Made of rubber, the gears mesh with each other during rotation but do not completely jam, providing damping to prevent the rubber gears 605 from rotating too freely. This allows the replacement scraper assembly 12 to be rotated to the opening of the hollow semi-cylinder 202, facilitating the removal of the scraper assembly 12 and preventing it from falling out when the pull-out assembly 2 is removed. This makes the dental cleaning pen both portable and replaceable. Additionally, the protective sponge 602 protects the marking chip 1205 mounted on the surface of the locking block 1201 from scratches and damage.

The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the controller 104, mobile battery 107, chip card reader 306 and display panel 9 will not be explained in detail.
