Description

Technical Field

[0001] This utility model relates to the field of oral cleaning tools, and specifically to a dental flosser with an ultra-small volume. Background Technology

[0002] As people pay more and more attention to oral health, a variety of teeth cleaning tools have appeared on the market. Ultrasonic dental scalers use the high frequency and high energy generated by ultrasonic waves to drive the scaler, loosening the small tartar attached to the teeth, removing plaque and other debris, leaving teeth clean and maintaining oral health.

[0003] Chinese utility model patent application number 202320619701.8 discloses a dental cleaning device, which includes a hollow face shell. A bottom shell is fitted onto the outer wall of the face shell. A control panel and a switch button are provided on the outer wall of the bottom shell. A hollow top cover is provided on the left side of the face shell. An external dental cleaning head for cleaning the outer side of the teeth and an internal dental cleaning head for cleaning the inner side of the teeth are provided at the end of the top cover away from the face shell. An ultrasonic vibration component is provided inside the cavity of the face shell, and an endoscope component is provided on the outer wall of the top cover.

[0004] Because the ultrasonic vibration component is installed inside the cavity of the face shell (equivalent to a support), and the battery and circuit board are horizontally stacked at the bottom of the face shell, and then the bottom shell is fitted on the outer wall of the bottom of the face shell, this design structure results in a relatively large size of the entire dental flosser, especially the large diameter of the bottom shell, which in turn makes the overall size of the dental flosser larger. It is not convenient to hold, store or carry, causing great inconvenience to users.

[0005] In view of the above, the inventors propose the following technical solution. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dental flosser with an ultra-small volume.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a dental scaler with an ultra-small volume includes: a cylindrical shell having a main mounting cavity arranged along its length; a control component including a bracket, a control board, and a battery, the bracket having a first mounting position and a second mounting position spaced apart along its length; the control board and the battery are respectively disposed in the first mounting position and the second mounting position, and the control component is disposed through the main mounting cavity; an ultrasonic transducer disposed in the upper part of the main mounting cavity and fastened by a fastener, the ultrasonic transducer being placed on the upper end of the bracket and electrically connected to the control board; a dental scaler head detachably mounted on the upper end of the ultrasonic transducer and placed outside the upper end of the cylindrical shell; and a base disposed through and fixed in the lower part of the main mounting cavity.

[0008] Furthermore, in the above technical solution, the first mounting position includes a first recessed groove disposed on the upper side of the bracket and a receiving groove disposed at the bottom of the first recessed groove. The receiving groove also penetrates the outer surface of the bracket. The control board is embedded and fixed in the first recessed groove. The small transformer disposed on the control board is installed into the receiving groove from the outside to the inside and exposed on the outer surface of the bracket. The outer surface of the small transformer does not protrude from the outer surface of the bracket.

[0009] Furthermore, in the above technical solution, the second mounting position is located at the lower part of the bracket and extends laterally through the outer surfaces of both sides of the lower part of the bracket. The battery is installed in the second mounting position from the outside to the inside and is exposed on the outer surfaces of both sides of the lower part of the bracket. The outer surface of the battery does not protrude from the outer surface of the bracket.

[0010] Furthermore, in the above technical solution, a first protrusion is provided on the upper outer side of the ultrasonic transducer, and an annular lamp plate is sleeved on the first protrusion. An LED for illumination is provided on the annular lamp plate, and the fixing member is a light guide sleeve, which is placed above the LED and used to guide the light emitted by the LED to the outside.

[0011] Furthermore, in the above technical solution, a first limiting plane is provided on the outer side of the first protrusion, and a second limiting plane adapted to the first limiting plane is provided on the inner wall of the annular lamp plate, and the second limiting plane is in contact with the first limiting plane.

[0012] Furthermore, in the above technical solution, a second boss is provided on the upper outer side of the ultrasonic transducer. The size of the second boss is smaller than that of the first boss, and the second boss is located above the first boss. A sealing ring is fitted on the second boss. A limiting groove is provided on the lower inner side of the fixing member. The limiting groove is fitted on the sealing ring and squeezes the sealing ring, so that the lower inner side of the fixing member and the second boss form a sealed assembly.

[0013] Furthermore, in the above technical solution, the upper end of the fastener is formed with a horizontally outward protruding flange, the lower end of the fastener is embedded and fixed to the upper part of the main mounting cavity, and the flange abuts against the upper surface of the cylindrical outer shell.

[0014] Furthermore, in the above technical solution, the fixing member has a sealing channel opening upward along its lower end, and the fixing member has an installation channel opening downward along its upper end that penetrates the sealing channel. The upper end of the ultrasonic transducer passes through the sealing channel and forms a sealed assembly. The upper end of the ultrasonic transducer also passes through the sealing channel to extend into the installation channel and forms a gap with the inner wall of the installation channel. The dental cleaning head passes through the installation channel from top to bottom and is fixedly connected to the upper end of the ultrasonic transducer by threads.

[0015] Furthermore, in the above technical solution, a shock-absorbing pad is provided between the lower end of the ultrasonic transducer and the upper end of the support.

[0017] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention provides a first mounting position and a second mounting position that are spaced apart along its length inside the bracket, and sets the control board and the battery in the first mounting position and the second mounting position respectively, that is, the control board and the battery are distributed vertically at intervals, instead of being horizontally stacked in the same mounting position of the bracket. This can minimize the external size of the bracket, thereby reducing the diameter of the cylindrical shell and making the overall volume of the present invention smaller. On this basis, the present invention also sets the ultrasonic transducer in the upper part of the main mounting cavity in the cylindrical shell and at the upper end of the bracket, instead of directly installing it in the bracket. This can further reduce the external size of the bracket, thereby reducing the diameter of the cylindrical shell and making the overall volume of the present invention smaller, forming a slender and ultra-small dental flosser, which is easy for users to hold and easy to store and carry, and is extremely convenient to use.

[0026] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0027] See Figure 1-8 As shown, a dental flosser with an ultra-small volume includes: a cylindrical shell 1, a control component 200, an ultrasonic transducer 5, a flossing head 7, and a base 8.

[0028] The ultrasonic transducer 5 is installed in the middle of the inside of the cylindrical housing 1. The ultrasonic transducer 5 is installed in the upper part of the inside of the cylindrical housing 1. The base 8 is installed in the bottom of the inside of the cylindrical housing 1. The dental cleaning head 7 is installed on the upper end of the ultrasonic transducer 5 and extends out of the cylindrical housing 1.

[0029] Specifically, the cylindrical housing 1 has a main mounting cavity 11 arranged along its length; the control component 200 includes a bracket 2, a control board 3, and a battery 4. The bracket 2 is provided with a first mounting position 21 and a second mounting position 22 spaced apart along its length; the control board 3 and the battery 4 are respectively disposed in the first mounting position 21 and the second mounting position 22, and the control component 200 is disposed through the main mounting cavity 11; the ultrasonic transducer 5 is disposed on the upper part of the main mounting cavity 11 and fastened by a fastener 6, and the ultrasonic transducer 5 is placed on the upper end of the bracket 2 and electrically connected to the control board 3; the dental cleaning head 7 is detachably installed on the upper end of the ultrasonic transducer 5 and placed outside the upper end of the cylindrical housing 1; the base 8 is disposed through and fixed to the lower part of the main mounting cavity 11 to limit the control component 200 within the cylindrical housing 1. This invention features a first mounting position 21 and a second mounting position 22 spaced apart along the length of the bracket 2. The control board 3 and the battery 4 are respectively positioned in the first mounting position 21 and the second mounting position 22, i.e., the control board 3 and the battery 4 are distributed vertically at intervals, rather than being horizontally stacked in the same mounting position on the bracket. This minimizes the external dimensions of the bracket, thereby reducing the diameter of the cylindrical shell 1 and making the overall size of the invention smaller. Furthermore, the ultrasonic transducer 5 is positioned in the upper part of the main mounting cavity 11 in the cylindrical shell 1, located at the upper end of the bracket 2, rather than being directly installed inside the bracket 2. This further reduces the external dimensions of the bracket, thereby reducing the diameter of the cylindrical shell 1 and making the overall size of the invention even smaller, forming a slender and ultra-small dental flosser that is easy for users to hold, store, and carry, making it extremely convenient to use.

[0030] Furthermore, the upper and lower external dimensions of the cylindrical outer shell 1 are the same, which is also a factor that reduces the overall size of the present invention.

[0031] The cylindrical outer shell 1 is also provided with a button 10. The inner side of the button 10 extends from the outside to the inside into the main mounting cavity 11 and is connected to the control switch 30 on the control board 3, so that the control switch 30 can be controlled to work by pressing the button 10.

[0032] The outer side of the cylindrical housing 1 is also provided with a row of indicator light holes 100, which correspond to the LED indicator lights 300 on the control board 3.

[0033] The assembly structure of the control component 200 will be described in detail below.

[0034] The first mounting position 21 includes a first recess 211 disposed on the upper side of the bracket 2 and a receiving groove 212 disposed at the bottom of the first recess 211. The receiving groove 212 also penetrates the outer surface of the bracket 2. The control board 3 is embedded and fixed in the first recess 211. The small transformer 31 disposed on the control board 3 is inserted into the receiving groove 212 from the outside in and exposed on the outer surface of the bracket 2. This allows the entire control board 3 to be accommodated in the smallest possible space, especially the small transformer 31, which can reduce or reduce the overall size of the bracket 2. Furthermore, the outer surface of the small transformer 31 does not protrude from the outer surface of the bracket 2, and it will not affect the subsequent direct insertion of the control component 200 into the main mounting cavity 11 of the cylindrical housing 1, ensuring smooth assembly and protecting the small transformer 31. In addition, the small transformer 31 used in this invention has a small size, which can also reduce the overall size of the bracket 2.

[0035] The second mounting position 22 is located at the lower part of the bracket 2 and extends laterally through both outer surfaces of the lower part of the bracket 2. The battery 4 is inserted into the second mounting position 22 from the outside in and is exposed on both outer surfaces of the lower part of the bracket 2. The outer surface of the battery 4 does not protrude from the outer surface of the bracket 2, which can reduce or decrease the overall size of the bracket 2, further making the overall size of the dental hygienist smaller. Since the outer surface of the battery 4 does not protrude from the outer surface of the bracket 2, it will not affect the subsequent direct insertion of the control component 200 into the main mounting cavity 11 of the cylindrical outer shell 1, ensuring smooth assembly and protecting the battery 4. The battery 4 is a rechargeable battery, such as a lithium battery.

[0036] The assembly structure of the ultrasonic transducer 5 is described below.

[0037] The ultrasonic transducer 5 has a first protrusion 51 on its upper outer surface. A ring-shaped lamp plate 9 is fitted onto the first protrusion 51, and an LED 91 for illumination is mounted on the ring-shaped lamp plate 9. The fixing member 6 is a light guide sleeve, which is placed above the LED 91 and is used to guide the light emitted by the LED 91 to the outside. This enables the present invention to achieve the function of illumination. That is, when cleaning teeth with the cleaning head of the dental scaler, the light emitted by the LED 91 is guided to the outside through the light guide sleeve and illuminates the teeth. This allows the user to clearly observe the cleaning status of the teeth, so as to achieve more effective cleaning and is extremely convenient to use. In addition, since the ring-shaped lamp plate 9 is directly fitted onto the upper outer surface of the ultrasonic transducer 5, its assembly structure is simple. It does not require processing the straight cylindrical shell 1 to set the mounting position for the ring-shaped lamp plate 9, thus reducing costs to a certain extent.

[0038] To make the assembly structure of the ring lamp plate 9 more stable after it is fitted onto the first protrusion 51 on the upper part of the ultrasonic transducer 5, the following design is made: a first limiting plane 511 is provided on the outer side of the first protrusion 51, and a second limiting plane 92 adapted to the first limiting plane 511 is provided on the inner wall. The second limiting plane 92 contacts the first limiting plane 511 and can play a limiting role, which can prevent rotation between the two and ensure the stability of the assembly structure.

[0039] To improve the sealing performance of the ultrasonic transducer 5 assembly structure, the following design is also made: a second boss 52 is provided on the upper outer side of the ultrasonic transducer 5. The size of the second boss 52 is smaller than that of the first boss 51, and the second boss 52 is located above the first boss 51. A sealing ring 53 is fitted on the second boss 52. A limiting groove 61 is provided on the lower inner side of the fixing member 6. The limiting groove 61 is fitted on the sealing ring 53 and squeezes the sealing ring 53, so that the lower inner side of the fixing member 6 and the second boss 52 form a sealed assembly, thereby improving the sealing performance of the ultrasonic transducer 5 assembly structure.

[0040] The upper end of the fastener 6 is formed with a horizontally protruding flange 62. The lower end of the fastener 6 is embedded and fixed to the upper part of the main mounting cavity 11, and the flange 62 abuts against the upper surface of the cylindrical shell 1. This can also improve the waterproof performance between the fastener 6 and the cylindrical shell 1. That is, the connection between the fastener 6 and the cylindrical shell 1 is horizontally distributed rather than vertically distributed, which can effectively prevent water from entering directly and achieve good waterproof performance.

[0041] The fixing member 6 has a sealing channel 63 extending upward from its lower end, and an installation channel 64 extending downward through the sealing channel 63 extending downward from its upper end. The upper end of the ultrasonic transducer 5 passes through the sealing channel 63 and forms a sealed assembly. The upper end of the ultrasonic transducer 5 also passes through the sealing channel 63 to extend into the installation channel 64 and forms a gap with the inner wall of the installation channel 64. The dental cleaning head 7 is inserted into the installation channel 64 from top to bottom and is fixedly connected to the upper end of the ultrasonic transducer 5 by threads.

[0042] The fixing member 6 is also sleeved on the outside of the first boss 51 on the inner wall of the sealing channel 63 and placed on the upper end of the first boss 51. The fixing member 6 is also provided with a third limiting plane 60 on the inner wall of the sealing channel 63, which is adapted to the first limiting plane 511. The third limiting plane 60 is also connected to the first limiting plane 511, which can play a limiting role, prevent rotation between the two, and ensure the stability of the assembly structure.

[0043] An anti-vibration pad 54 is provided between the lower end of the ultrasonic transducer 5 and the upper end of the bracket 2. The anti-vibration pad 54 has a good vibration isolation effect, preventing the vibration generated by the ultrasonic transducer 5 from being transmitted to the bracket 2, thereby protecting the control component 200 and improving product quality.

[0044] The base 8 houses a charging board 32 electrically connected to the control board 3. The charging board 32 has a charging interface 321. The lower end of the base 8 has a hole through which the lower end of the charging interface 321 protrudes, exposed below the base 8. The base 8 is also connected to a sealing plug 81 that seals the hole. When charging the battery, the sealing plug 81 is opened outwards. Because the base 8 is connected to the sealing plug 81, the sealing plug 81 hangs below the base 8, preventing it from being lost. With the sealing plug 81 open, the charging interface 321 is exposed. A charging cable is then connected to the charging interface 321 to charge the battery. After charging is complete, the sealing plug 81 is closed again to prevent foreign objects from entering and damaging the charging interface 321.

[0045] In summary, this utility model provides a first mounting position 21 and a second mounting position 22 spaced apart along the length of the bracket 2, and respectively sets the control board 3 and the battery 4 in the first mounting position 21 and the second mounting position 22. That is, the control board 3 and the battery 4 are distributed vertically at intervals, rather than being horizontally stacked in the same mounting position of the bracket. This can minimize the external size of the bracket, thereby reducing the diameter of the cylindrical shell 1 and making the overall volume of this utility model smaller. On this basis, this utility model also sets the ultrasonic transducer 5 in the upper part of the main mounting cavity 11 in the cylindrical shell 1 and at the upper end of the bracket 2, rather than directly installed in the bracket 2. This can further reduce the external size of the bracket, thereby reducing the diameter of the cylindrical shell 1 and making the overall volume of this utility model smaller, forming a slender and ultra-small dental cleaner, which is easy for users to hold, easy to store and carry, and extremely convenient to use.

[0046] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model should be included in the scope of the claims of the present utility model.
