Description

Technical Field

[0001] The present application relates to the field of teeth cleaning devices, and in particular to a teeth pick and a control method of the teeth pick. Background Art

[0002] As people's health awareness increases, the demand for personal hygiene products is growing, especially in terms of oral health. Dental floss is an effective tooth cleaning tool for cleaning food residues and dental plaque between adjacent surfaces and teeth. It can easily remove dirt in areas that are difficult for toothbrush bristles to reach, and plays a vital role in maintaining oral hygiene and preventing dental diseases.

[0003] However, when using traditional dental floss to clean teeth deep in the mouth, the hand placement angle and movement range are easily restricted by the mouth, making it difficult for users to completely clean the teeth deep in the mouth, reducing the cleaning effect of the teeth. Summary of the invention

[0004] In order to reduce the degree of restriction of the mouth on the placement angle and movement range of the hands and improve the cleaning effect of teeth, the present application provides a teeth pick.

[0005] The present application further proposes a control method for a teeth pick.

[0006] The present application provides a tooth pick adopting the following technical solution: A toothpick comprises: a shell, the shell defines an installation space, the outer peripheral wall of the shell is provided with a connecting hole, the connecting hole is connected to the installation space; a pivot member, the pivot member is movably arranged in the shell, the pivot member is opposite to the connecting hole; a toothpick member, the end of the toothpick member passes through the connecting hole and is pivotally connected to the pivot member, and the toothpick member is pivotally connected to the shell, and the toothpick member is suitable for abutting against teeth.

[0007] A driving assembly is disposed in the shell and is transmission-connected to the pivot member, the driving assembly is used to drive the pivot member to reciprocate along a first direction of the shell, so that the pivot member drives the toothpick member to reciprocate around the pivot axis of the toothpick member, and the driving assembly is also used to drive the toothpick member to vibrate, so that the toothpick member can scrape off debris on the teeth.

[0008] By adopting the above technical solution, the user holds the housing with the hand, and then the user drives the toothpick through the housing to extend into the gap between two teeth, and makes the toothpick abut against the outer peripheral wall of the tooth. The driving assembly drives the pivoting member to drive the toothpick to rotate reciprocally, and the toothpick reciprocally extends into or out of the gap between the two teeth, so that the toothpick scrapes off the debris on the teeth. Moreover, the driving assembly drives the toothpick to vibrate, so that the toothpick further scrapes off the debris on the teeth. Compared with the prior art, the hand does not touch the mouth, thereby reducing the degree of restriction of the placement angle and movement amplitude of the mouth on the hand, and the debris on the teeth deep in the oral cavity can be scraped off by the toothpick, and thus the cleaning effect of the teeth can be improved.

[0009] Preferably, a pivoting hole and a first kidney-shaped hole are provided on the outer peripheral wall of the toothpick. Both the pivoting hole and the first kidney-shaped hole are located inside the housing. Along the height direction of the housing, the pivoting hole and the first kidney-shaped hole are spaced apart. A pivoting shaft is provided inside the housing, and the pivoting shaft and the pivoting hole are pivotally matched. The pivoting member is provided with a first driving portion, and the first driving portion is in transmission connection with the first kidney-shaped hole.

[0010] By adopting the above technical solution, the pivoting member drives the first driving portion to reciprocate in the first kidney-shaped hole along the first direction of the housing. When the first driving portion moves leftward and abuts against the left side wall of the first kidney-shaped hole, the first driving portion drives the end of the toothpick away from the pivoting member to rotate rightward around the pivoting shaft. When the first driving portion moves rightward and abuts against the right side wall of the first kidney-shaped hole, the first driving portion drives the end of the toothpick away from the pivoting member to rotate leftward around the pivoting shaft, so that the technical effect that the driving assembly drives the toothpick to rotate reciprocally around the pivoting axis between the toothpick and the housing can be achieved.

[0011] Preferably, the pivoting member is in guiding cooperation with the housing. The driving assembly includes a driving member and a vibrating member. A second kidney-shaped hole is provided on the end wall of the pivoting member opposite to the toothpick. The output end of the driving member is provided with a transmission member. The transmission member is provided with a second driving portion. The central axis of the second driving portion and the central axis of the driving member are eccentrically arranged. The second driving portion is in transmission connection with the second kidney-shaped hole. The driving member is used to drive the transmission member to drive the pivoting member to reciprocate along the first direction of the housing. The vibrating member is used to drive the housing to vibrate, so that the housing drives the toothpick to vibrate.

[0012] By adopting the above technical solution, the driving member drives the second driving part to rotate around the central axis of the driving member in the second kidney-shaped hole. Along the first direction of the housing, when the second driving part moves leftward and abuts against the left side wall of the second kidney-shaped hole, the second driving part drives the pivoting member to move leftward. When the second driving part moves rightward and abuts against the right side wall of the second kidney-shaped hole, the second driving part drives the pivoting member to move rightward. Thus, the technical effect that the driving assembly drives the pivoting member to reciprocate along the first direction of the housing can be achieved.

[0013] Preferably, a guiding member is provided in the housing. The central axis of the guiding member is arranged parallel to the first direction of the housing, and the guiding member is in guiding cooperation with the pivoting member.

[0014] By adopting the above technical solution, the guiding member passes through the pivoting member, and the pivoting member is in sliding cooperation with the guiding member. When the driving member drives the transmission member to drive the pivoting member to move, the guiding member guides the pivoting member. Thus, the technical effect that the pivoting member moves along the first direction of the housing can be achieved.

[0015] Preferably, there are a plurality of guiding members, and the plurality of guiding members are spaced apart along the second direction of the housing.

[0016] By adopting the above technical solution, the pivoting member is guided by a plurality of guiding members, and multiple parts of the pivoting member can move along the first direction of the housing. Thus, the movement stability of the pivoting member can be improved.

[0017] Preferably, the dental cleaner further includes: a speed detection member and a controller. The speed detection member is arranged in the housing. A marking member is provided on the outer peripheral wall of the transmission member, and the marking member is adapted to face the speed detection member. The speed detection member is used to detect the rotation speed of the transmission member through the marking member. Both the speed detection member and the driving member are communicatively connected to the controller, and the controller is used to adjust the rotation speed of the driving member according to the detection signal of the speed detection member.

[0018] By adopting the above technical solution, the controller generates the interval time between two detection signals through the speed detection member to determine the rotation speed of the transmission member, and thus determines the rotation speed of the dental cleaning member through the rotation speed of the transmission member. When the rotation speed of the dental cleaning member is greater than the maximum value of the preset rotation speed range, the controller reduces the rotation speed of the driving member, which can avoid excessive wear of the dental floss and damage to the gums caused by too high a rotation speed of the dental cleaning member. When the rotation speed of the dental cleaning member is less than the minimum value of the preset rotation speed range, the controller increases the rotation speed of the driving member, which can avoid the inability to effectively scrape off the debris on the teeth due to too low a rotation speed of the dental cleaning member.

[0019] Preferably, the toothpick includes a connecting rod and a cleaning member. The connecting rod is pivotally connected to the housing. Along the height direction of the housing, one end of the connecting rod is pivotally connected to the pivoting member, and the other end is provided with a connecting hole. The cleaning member is pivotally mounted in the connecting hole, and the cleaning member is used for scraping debris on the teeth.

[0020] By adopting the above technical solution, by rotating the cleaning member to adjust the angle of the cleaning member, the cleaning member can abut against the teeth at different positions in the oral cavity, and the cleaning member can scrape the debris on the teeth at different positions in the oral cavity, thereby improving the cleaning effect of the teeth.

[0021] Preferably, the connecting rod includes a pivoting portion and a connecting portion. The cleaning member is pivotally mounted on the connecting portion. The pivoting portion is pivotally connected to both the housing and the pivoting member. The connecting portion is provided with a receiving hole, and the inner peripheral wall of the receiving hole is provided with a first clamping structure. The outer peripheral wall of the pivoting portion is provided with a second clamping structure. The connecting portion is sleeved on the outer peripheral wall of the pivoting portion. Through the clamping cooperation of the first clamping structure and the second clamping structure, the pivoting portion and the connecting portion are detachably connected and matched.

[0022] By adopting the above technical solution, when the cleaning member is worn out and cannot be used continuously, a driving force away from the pivoting portion is applied to the connecting portion, and the first clamping structure and the second clamping structure are separated to disassemble the cleaning member from the pivoting portion. Then, the unused cleaning member is installed on the pivoting portion, the pivoting portion extends into the receiving hole of the connecting portion, and the first clamping structure and the second clamping structure are clamped and matched, thereby achieving the technical effect of quickly replacing the cleaning member.

[0023] Preferably, the toothpick further includes a distance detection member and a controller. The distance detection member is disposed in the toothpick. The distance detection member is used for detecting the distance between the toothpick and the gum. The distance detection member and the driving assembly are both communicatively connected to the controller. The controller is used for adjusting the vibration intensity of the driving assembly according to the detection signal of the distance detection member, and controlling the driving assembly to stop or start driving the toothpick to rotate.

[0024] By adopting the above technical solution, when the interval distance between the toothpick and the gum is not greater than the first preset interval distance, the controller reduces the vibration intensity of the vibrating member according to the detection signal of the distance detection member, thereby avoiding that when the interval distance between the toothpick and the gum is too small, the too large vibration intensity of the toothpick causes damage to the gum. When the interval distance between the toothpick and the gum is not greater than the second preset interval distance, the controller controls the driving member to stop driving the toothpick to rotate according to the detection signal of the distance detection member, thereby avoiding that the continuous rotation of the toothpick causes the toothpick to squeeze the gum and cause damage to the gum, and further improving the use reliability of the toothpick.

[0025] The control method for a toothpick cleaner provided by this application adopts the following technical solution: A control method for a toothpick cleaner, the control method for the toothpick cleaner being applicable to the above-mentioned toothpick cleaner, comprising: detecting in real time the spacing distance between the toothpick member and the gum, and determining whether the spacing distance is not greater than a first preset spacing distance; if the spacing distance is not greater than the first preset spacing distance, reducing the vibration intensity of the driving assembly, and then determining whether the spacing distance is not greater than a second preset spacing distance; if the spacing distance is not greater than the second preset spacing distance, the driving assembly stops driving the toothpick member to rotate.

[0026] By adopting the above technical solution, through the control method of the toothpick cleaner in the embodiment of this application, when the spacing distance between the toothpick member and the gum is not greater than the first preset spacing distance, the vibration intensity of the vibrating member is reduced, which can prevent the vibrating member from having too high a vibration intensity and damaging the gum. When the spacing distance between the toothpick member and the gum is not greater than the second preset spacing distance, the driving member stops driving the toothpick member to rotate, which can prevent the toothpick member from continuously rotating and squeezing the gum, resulting in gum damage.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. The user holds the housing by hand, and then the user drives the toothpick member to extend into the gap between two teeth through the housing and makes the toothpick member abut against the outer peripheral wall of the tooth. The driving assembly drives the pivot member to drive the toothpick member to rotate reciprocally. The toothpick member reciprocally extends into or out of the gap between two teeth, so that the toothpick member scrapes the debris on the teeth, and the driving assembly drives the toothpick member to vibrate, so that the toothpick member further scrapes the debris on the teeth. Compared with the prior art, the hand does not touch the mouth, thereby reducing the degree of restriction of the placement angle and movement amplitude of the hand by the mouth, and the debris on the teeth in the deep part of the oral cavity can be scraped by the toothpick member, thereby improving the cleaning effect of the teeth; 2. The controller generates the interval time between two detection signals through the speed detection member to determine the rotation speed of the transmission member, and thus determines the rotation speed of the toothpick member through the rotation speed of the transmission member. When the rotation speed of the toothpick member is greater than the maximum value of the preset rotation speed range, the controller reduces the rotation speed of the driving member, which can prevent the toothpick member from having too high a rotation speed and causing excessive wear of the dental floss and damage to the gum. When the rotation speed of the toothpick member is less than the minimum value of the preset rotation speed range, the controller increases the rotation speed of the driving member, which can prevent the toothpick member from having too low a rotation speed and being unable to effectively scrape the debris on the teeth; 3. When the cleaning member is worn out and cannot be used anymore, apply a driving force away from the pivoting portion to the connecting portion, and the first and second latching structures are separated to disassemble the cleaning member from the pivoting portion. Then, install an unused cleaning member on the pivoting portion. The pivoting portion extends into the receiving hole of the connecting portion, and the first and second latching structures are engaged with each other, thereby achieving the technical effect of quickly replacing the cleaning member.

Detailed Description of the Embodiment

[0030] The following will Figures 1-7 further describe the present application in detail with reference to the accompanying

[0031] An embodiment of the present application discloses a dental pick 100.

[0032] Refer toFigures 1-3 , the dental pick 100 according to the embodiments of the present application includes: a housing 1, a pivot member 2, a dental pick member 3, and a driving assembly 4. The housing 1 defines an installation space 11. A communication hole 12 is provided on the outer peripheral wall of the housing 1, and the communication hole 12 communicates with the installation space 11. Specifically, along the height direction of the housing 1, the communication hole 12 is located on the upper end wall of the housing 1. When using the dental pick 100, the user holds the housing 1 by hand, and the height direction of the housing 1 may refer to Figure 2 the up and down direction in

[0033] The pivot member 2 is movably arranged in the housing 1. The pivot member 2 is opposite to the communication hole 12. The lower end of the dental pick member 3 passes through the communication hole 12 and is pivotally connected to the pivot member 2, and the dental pick member 3 is pivotally connected to the housing 1. The dental pick member 3 is adapted to abut against the outer peripheral wall of the tooth. Specifically, the dental pick member 3 extends into the gap between two adjacent teeth, and then the dental pick member 3 abuts against the outer peripheral wall of the tooth. By driving the dental pick member 3 to extend into or out of the gap between the two teeth, the dental pick member 3 can scrape off the debris on the outer peripheral wall of the tooth.

[0034] In some specific embodiments, the dental pick member 3 may be dental floss.

[0035] The driving assembly 4 is arranged in the housing 1 and is in transmission connection with the pivot member 2. The driving assembly 4 is used to drive the pivot member 2 to reciprocate in a first direction of the housing 1, so that the pivot member 2 drives the dental pick member 3 to reciprocally rotate around the pivot axis 13 between the dental pick member 3 and the housing 1. The driving assembly 4 is also used to drive the dental pick member 3 to vibrate, so that the dental pick member 3 can scrape off the debris on the teeth. The first direction of the housing 1 may be Figure 2 the left and right direction in

[0036] Specifically, when the dental pick member 3 extends into the gap between two teeth and abuts against the outer peripheral wall of the tooth, the driving assembly 4 drives the pivot member 2 to reciprocate in a first direction of the housing 1. The pivot member 2 drives the dental pick member 3 to reciprocally rotate around the pivot axis 13 between the dental pick member 3 and the housing 1. The dental pick member 3 reciprocally extends into or out of the gap between the two teeth, so that the dental pick member 3 can scrape off the debris on the outer peripheral wall of the tooth.

[0037] Moreover, the driving assembly 4 drives the housing 1 to vibrate, and the housing 1 drives the dental pick member 3 to vibrate. During the process of the dental pick member 3 scraping off the debris on the outer peripheral wall of the tooth, the dental pick member 3 can better scrape off the debris on the outer peripheral wall of the tooth, improving the cleaning effect of the teeth.

[0038] It should be noted that the toothpick 3 does not rotate 360° around the pivot axis 13 of the toothpick 3. The toothpick 3 only reciprocally rotates around the pivot axis 13 of the toothpick 3 within a preset rotation range. In some specific embodiments, the preset rotation range of the toothpick 3 can be within 120° with the pivot axis 13 of the toothpick 3 as the center of the circle. That is to say, the end of the toothpick 3 away from the pivot member 2 reciprocally rotates within a range of 120°.

[0039] Thus, the user holds the housing 1 by hand, and then the user drives the toothpick 3 through the housing 1 to extend into the gap between two teeth, and makes the toothpick 3 abut against the outer peripheral wall of the teeth. The driving assembly 4 drives the pivot member 2 to drive the toothpick 3 to reciprocally rotate. The toothpick 3 reciprocally extends into or out of the gap between two teeth, so that the toothpick 3 scrapes off the debris on the teeth. And the driving assembly 4 drives the toothpick 3 to vibrate, so that the toothpick 3 further scrapes off the debris on the teeth. Compared with the prior art, the hand does not touch the mouth, thereby reducing the degree of restriction of the placement angle and movement amplitude of the mouth on the hand, and the debris on the teeth in the deep part of the oral cavity can be scraped off by the toothpick 3, and thus the cleaning effect of the teeth can be improved.

[0040] Referring to Figure 3 、 Figure 5 and Figure 6 , in some embodiments of the present application, a pivot hole 31 and a first waist-shaped hole 32 are provided on the outer peripheral wall of the toothpick 3. Both the pivot hole 31 and the first waist-shaped hole 32 are configured as through holes. Specifically, along the second direction of the housing 1, both the pivot hole 31 and the first waist-shaped hole 32 are located on the front end wall of the toothpick 3, and both the pivot hole 31 and the first waist-shaped hole 32 are located inside the housing 1. Along the height direction of the housing 1, the pivot hole 31 and the first waist-shaped hole 32 are spaced apart. The first waist-shaped hole 32 is located below the pivot hole 31. A pivot shaft 13 is provided inside the housing 1. The pivot shaft 13 and the pivot hole 31 are pivotally matched. The pivot member 2 is provided with a first driving portion 21. The first driving portion 21 is in transmission connection with the first waist-shaped hole 32. Along the first direction of the housing 1, the first driving portion 21 is adapted to abut against the left end wall or the right end wall of the first waist-shaped hole 32. The second direction of the housing 1 may refer to Figure 5 the front-back direction in

[0041] Specifically, the driving assembly 4 drives the pivoting member 2 to reciprocate in the first direction of the housing 1. The pivoting member 2 drives the first driving portion 21 to reciprocate in the first direction of the housing 1 within the first kidney-shaped hole 32. When the first driving portion 21 moves to the left and abuts against the left side wall of the first kidney-shaped hole 32, the first driving portion 21 drives the end portion of the toothpick member 3 away from the pivoting member 2 to rotate to the right around the pivot axis 13. When the first driving portion 21 moves to the right and abuts against the right side wall of the first kidney-shaped hole 32, the first driving portion 21 drives the end portion of the toothpick member 3 away from the pivoting member 2 to rotate to the left around the pivot axis 13. Thus, the technical effect that the driving assembly 4 drives the toothpick member 3 to reciprocally rotate around the pivot axis 13 between the toothpick member 3 and the housing 1 can be achieved.

[0042] Referring to Figure 2 , Figure 3 and Figure 6 , in some embodiments of the present application, the pivoting member 2 is in guiding cooperation with the housing 1. The driving assembly 4 includes a driving member 41 and a vibrating member 42. A second kidney-shaped hole 22 is provided on the end wall of the pivoting member 2 opposite to the toothpick member 3, and the second kidney-shaped hole 22 is configured as a blind hole. In the height direction of the housing 1, the toothpick member 3 is located above the pivoting member 2, the driving member 41 is located below the pivoting member 2, and the second kidney-shaped hole 22 is located on the lower end wall of the pivoting member 2.

[0043] The output end of the driving member 41 is provided with a transmission member 411. The upper end wall of the transmission member 411 is provided with a second driving portion 4111. The central axis of the second driving portion 4111 and the central axis of the driving member 41 are eccentrically arranged. The second driving portion 4111 is in transmission connection with the second kidney-shaped hole 22. The driving member 41 is used to drive the transmission member 411 to drive the pivoting member 2 to reciprocate in the first direction of the housing 1.

[0044] Specifically, the driving member 41 drives the transmission member 411 to rotate around the central axis of the driving member 41. The transmission member 411 drives the second driving portion 4111 to rotate around the central axis of the driving member 41 within the second kidney-shaped hole 22. In the first direction of the housing 1, when the second driving portion 4111 moves to the left and abuts against the left side wall of the second kidney-shaped hole 22, the second driving portion 4111 drives the pivoting member 2 to move to the left. When the second driving portion 4111 moves to the right and abuts against the right side wall of the second kidney-shaped hole 22, the second driving portion 4111 drives the pivoting member 2 to move to the right. Thus, the technical effect that the driving assembly 4 drives the pivoting member 2 to reciprocate in the first direction of the housing 1 can be achieved.

[0045] Moreover, the vibrating member 42 is used to drive the housing 1 to vibrate, so that the housing 1 drives the toothpick member 3 to vibrate. Thus, the technical effect that the driving assembly 4 drives the toothpick member 3 to vibrate can be achieved.

[0046] In some specific embodiments, the driving member 41 is preferably a motor, and the vibrating member 42 is preferably an electric motor or a linear vibrator, etc.

[0047] In some specific embodiments, the speed detection member may be a Hall sensor, and the identification member may be a magnet.

[0048] Referring to Figure 2 、 Figure 3 and Figure 6 In some embodiments of the present application, a guiding member 14 is provided in the housing 1. The central axis of the guiding member 14 is parallel to the first direction of the housing 1. That is to say, the left end of the guiding member 14 is connected and cooperated with the left side wall of the installation space 11, and the right end of the guiding member 14 is connected and cooperated with the right side wall of the installation space 11.

[0049] Moreover, the guiding member 14 is in guiding cooperation with the pivoting member 2. Specifically, the guiding member 14 passes through the pivoting member 2, and the pivoting member 2 is in sliding cooperation with the guiding member 14. When the driving member 41 drives the transmission member 411 to drive the pivoting member 2 to move, the guiding member 14 guides the pivoting member 2, so as to achieve the technical effect that the pivoting member 2 moves along the first direction of the housing 1, and can prevent the pivoting member 2 from deviating from the preset movement direction, so as to prevent the pivoting member 2 from being unable to drive the toothpick member 3 to reciprocate around the pivot axis 13 of the toothpick member 3, thereby improving the working reliability of the toothpick cleaner 100.

[0050] Referring to Figure 3 and Figure 6 In some embodiments of the present application, there are a plurality of guiding members 14. The plurality of guiding members 14 are spaced apart along the second direction of the housing 1. The plurality of guiding members 14 all pass through the pivoting member 2. By guiding the pivoting member 2 through the plurality of guiding members 14, multiple parts of the pivoting member 2 can move along the first direction of the housing 1, thereby improving the movement stability of the pivoting member 2.

[0051] Referring to Figure 3 In some embodiments of the present application, the toothpick cleaner 100 may further include: a speed detection member 5 and a controller. The speed detection member 5 is provided in the housing 1. An identification member 4112 is provided on the outer peripheral wall of the transmission member 411. The identification member 4112 is adapted to face the speed detection member 5. The speed detection member 5 is used to detect the rotation speed of the transmission member 411 through the identification member 4112. Both the speed detection member 5 and the driving member 41 are communicatively connected to the controller. The controller is used to adjust the rotation speed of the driving member 41 according to the detection signal of the speed detection member 5.

[0052] Specifically, the driving member 41 drives the transmission member 411 to drive the identification member 4112 to rotate around the central axis of the driving member 41. When the identification member 4112 faces the speed detection member 5, the speed detection member 5 is triggered and generates a detection signal. The controller determines the rotation speed of the transmission member 411 by the interval time between two detection signals generated by the speed detection member 5, so as to determine the rotation speed of the toothpick member 3 through the rotation speed of the transmission member 411. When the rotation speed of the toothpick member 3 is greater than the maximum value of the preset rotation speed range, the controller reduces the rotation speed of the driving member 41, which can avoid excessive wear of the dental floss and damage to the gums caused by too high a rotation speed of the toothpick member 3. When the rotation speed of the toothpick member 3 is less than the minimum value of the preset rotation speed range, the controller increases the rotation speed of the driving member 41, which can avoid the toothpick member 3 having too low a rotation speed to effectively scrape off the debris on the teeth.

[0053] In some specific embodiments, the speed detection member 5 can be a Hall sensor, and the identification member 4112 can be a magnet.

[0054] Referring to Figure 2 and Figure 4 In some embodiments of the present application, the toothpick member 3 includes a connecting rod 33 and a cleaning member 34. The connecting rod 33 is pivotally connected to the housing 1. Along the height direction of the housing 1, one end of the connecting rod 33 is pivotally connected to the pivot member 2, and a connecting hole 331 is provided at the other end of the connecting rod 33. Specifically, the lower end of the connecting rod 33 is pivotally connected to the pivot member 2, the upper end of the connecting rod 33 is provided with the connecting hole 331, and the pivot hole 31 and the first kidney-shaped hole 32 are both provided on the connecting rod 33.

[0055] Moreover, the cleaning member 34 is pivotally installed in the connecting hole 331. The cleaning member 34 is used to scrape off the debris on the teeth. By rotating the cleaning member 34 to adjust the angle of the cleaning member 34, the cleaning member 34 can abut against the teeth at different positions in the oral cavity, and the cleaning member 34 can scrape off the debris on the teeth at different positions in the oral cavity, thereby improving the cleaning effect of the teeth.

[0056] In some specific embodiments, the cleaning member 34 is preferably dental floss.

[0057] Referring to Figure 3 、 Figure 4 and Figure 6 In some embodiments of the present application, the connecting rod 33 includes a pivot portion 332 and a connecting portion 333. The cleaning member 34 is pivotally installed in the connecting portion 333, and the pivot portion 332 is pivotally connected to both the housing 1 and the pivot member 2. Specifically, along the height direction of the housing 1, the upper end of the connecting portion 333 is provided with the connecting hole 331, and the pivot hole 31 and the first kidney-shaped hole 32 are both provided on the pivot portion 332.

[0058] The lower end wall of the connecting portion 333 is provided with a receiving hole 3331. The inner peripheral wall of the receiving hole 3331 is provided with a first clamping structure 3332. The outer peripheral wall of the pivoting portion 332 is provided with a second clamping structure 3321. The connecting portion 333 is sleeved on the outer peripheral wall of the pivoting portion 332. That is to say, the pivoting portion 332 extends into the receiving hole 3331. The first clamping structure 3332 and the second clamping structure 3321 are clamped and matched to enable the pivoting portion 332 and the connecting portion 333 to be detachably connected and matched.

[0059] When the cleaning member 34 is worn out too much and cannot be used continuously, a driving force away from the pivoting portion 332 is applied to the connecting portion 333. The first clamping structure 3332 and the second clamping structure 3321 are separated to disassemble the cleaning member 34 from the pivoting portion 332. Then, the unused cleaning member 34 is installed on the pivoting portion 332. The pivoting portion 332 extends into the receiving hole 3331 of the connecting portion 333. The first clamping structure 3332 and the second clamping structure 3321 are clamped and matched, so that the technical effect of quickly replacing the cleaning member 34 can be achieved.

[0060] In some specific embodiments, the first clamping structure 3332 is configured as a clamping protrusion, and the second clamping structure 3321 is configured as a clamping recess.

[0061] Referring to Figure 4 , in some embodiments of the present application, the dental pick 100 may further include: a distance detection member 6 and a controller. The distance detection member 6 is disposed in the dental pick member 3. Specifically, along the height direction of the housing 1, the distance detection member 6 is disposed at the upper end portion of the pivoting portion 332. The distance detection member 6 is used to detect the distance between the dental pick member 3 and the gum. Both the distance detection member 6 and the driving assembly 4 are communicatively connected to the controller. The controller is used to adjust the vibration intensity of the driving assembly 4 according to the detection signal of the distance detection member 6, and to control the driving assembly 4 to stop or start driving the dental pick member 3 to rotate.

[0062] Specifically, the distance detection member 6 detects the interval distance between the dental pick member 3 and the gum. When the interval distance between the dental pick member 3 and the gum is not greater than the first preset interval distance, the controller reduces the vibration intensity of the vibrating member 42 according to the detection signal of the distance detection member 6, so as to avoid damage to the gum caused by excessive vibration intensity of the dental pick member 3 when the interval distance between the dental pick member 3 and the gum is too small. When the interval distance between the dental pick member 3 and the gum is not greater than the second preset interval distance, the controller controls the driving member 41 to stop driving the dental pick member 3 to rotate according to the detection signal of the distance detection member 6, so as to avoid damage to the gum caused by continuous rotation of the dental pick member 3 pressing on the gum, and further improve the use reliability of the dental pick member 3.

[0063] When the interval distance between the interdental cleaner 3 and the gum is greater than the second preset interval distance, the controller controls the driving member 41 to drive the interdental cleaner 3 to rotate. When the interval distance between the interdental cleaner 3 and the gum is greater than the first preset interval distance, the controller increases the vibration intensity of the vibrating member 42.

[0064] In some specific embodiments, the first preset interval distance can be 3 mm, and the second preset interval distance can be 0 mm. That is to say, when the interdental cleaner 3 does not move to the leftmost maximum stroke around the pivot axis 13 of the interdental cleaner 3, the interdental cleaner 3 abuts against the gum.

[0065] In some specific embodiments, the distance detection member 6 can be an ultrasonic sensor or an infrared sensor. The interval distance between the distance detection member 6 and the cleaning member 34 is a fixed value. The distance detection member 6 detects the distance between the gum and the distance detection member 6, and then subtracts the interval distance between the distance detection member 6 and the cleaning member 34 from the distance between the gum and the distance detection member 6 to obtain the interval distance between the cleaning member 34 and the gum.

[0066] Further, an accelerometer 7 and a gyroscope 8 are provided in the housing 1.

[0067] Based on this, the present application further discloses a control method for an interdental cleaner. The control method for the interdental cleaner is applicable to the interdental cleaner described in the above embodiments, as Figure 7 shown. According to the control method for the interdental cleaner described in the embodiments of the present application, the following steps are included: S1. Real-time detect the interval distance between the interdental cleaner and the gum, and determine whether the interval distance is not greater than the first preset interval distance. Specifically, the distance between the interdental cleaner and the gum is detected in real time through the distance detection member. That is to say, the interval distance between the cleaning member and the gum is detected in real time by the distance detection member, and then it is determined whether the interval distance between the cleaning member and the gum is not greater than the first preset interval distance.

[0068] S2. If the interval distance is not greater than the first preset interval distance, reduce the vibration intensity of the driving assembly, and then determine whether the interval distance is not greater than the second preset interval distance. Specifically, when the interval distance between the cleaning member and the gum is not greater than the first preset interval distance, control the vibration intensity of the vibrating member to decrease, so as to avoid damaging the gum by the excessive vibration intensity of the vibrating member. Then determine whether the interval distance between the cleaning member and the gum is not greater than the second preset interval distance.

[0069] In some specific embodiments, the vibration intensity of the vibrating member can include a first intensity value and a second intensity value, and the second intensity value is greater than the first intensity value. When the interdental cleaner starts to work, the vibration intensity of the vibrating member is the second intensity value. When the interval distance between the cleaning member and the gum is not greater than the first preset interval distance, the vibration intensity of the vibrating member is reduced to the first intensity value.

[0070] In some specific embodiments, the first preset interval distance may be 3 mm.

[0071] S3. If the interval distance is not greater than the second preset interval distance, the driving component stops driving the toothpick rotating member to rotate. Specifically, when the interval distance between the cleaning member and the gum is not greater than the second preset interval distance, the driving member is controlled to stop driving the cleaning member to rotate, so as to avoid the gum being damaged due to the continuous rotation of the toothpick rotating member pressing against the gum.

[0072] In some specific embodiments, the second preset interval distance may be 0 mm.

[0073] Through the control method of the toothpick cleaner of the embodiment of the present application, when the interval distance between the toothpick rotating member and the gum is not greater than the first preset interval distance, the vibration intensity of the vibration member is reduced, which can avoid the gum being damaged due to the excessive vibration intensity of the vibration member. When the interval distance between the toothpick rotating member and the gum is not greater than the second preset interval distance, the driving member stops driving the toothpick rotating member to rotate, which can avoid the gum being damaged due to the continuous rotation of the toothpick rotating member pressing against the gum.

[0074] In some embodiments of the present application, the control method of the toothpick cleaner may further include the following steps: S4. Real-time detect the motion data of the toothpick rotating member, and construct the motion trajectory of the toothpick rotating member according to the motion data.

[0075] Specifically, an accelerometer and a gyroscope are arranged in the housing. First, the motion data of the toothpick rotating member in the oral cavity, including position, motion direction, motion speed, motion acceleration and angle, are collected in real time through the position detection member, the accelerometer and the gyroscope. The motion trajectory of the toothpick rotating member in the oral cavity is calculated through the motion data, and the acquisition of the motion trajectory is continuous, so as to be able to track the motion trajectory of the toothpick rotating member in real time, and the actual motion path and relative position of the toothpick rotating member in the oral cavity can be completely depicted according to the motion trajectory.

[0076] Further, a three-dimensional coordinate system with the center of the oral cavity as the origin is established. By tracking the motion of the toothpick rotating member in real time, the motion trajectory of the toothpick rotating member is depicted in the coordinate system. The position change value and angle change value of the toothpick rotating member are obtained through the accelerometer and the gyroscope, and then the position change value and angle change value are combined with the motion data of the previous moment to determine the current position and posture of the toothpick rotating member.

[0077] It should be noted that the first tooth cleaned by the toothpick rotating member is a fixed tooth, and the first tooth cleaned by the toothpick rotating member may be an incisor, so that the position of the toothpick rotating member in the oral cavity can be accurately calculated.

[0078] S5. Real-time match the movement trajectory with the preset oral model to determine whether the movement trajectory covers the teeth adjacent to the teeth being cleaned by the interdental cleaner.

[0079] Specifically, match the movement trajectory of the interdental cleaner with the stored preset oral model, which contains the three-dimensional positions, shapes, and adjacent relationships of each tooth. Through the matching of the movement trajectory, it can be determined whether the interdental cleaner covers the area of the teeth adjacent to the teeth being cleaned. This matching process involves comparing the geometric positional relationship between the movement trajectory of the interdental cleaner and the preset oral model. If the movement trajectory of the interdental cleaner can coincide with the adjacent area of the teeth being cleaned, the interdental cleaner has covered the teeth adjacent to the teeth being cleaned. If not, the interdental cleaner has not covered the teeth adjacent to the teeth being cleaned.

[0080] Furthermore, the system has a standard model of the human oral structure built-in. When the user first uses the interdental cleaner, the position detector, accelerometer, and gyroscope will collect the movement data of the interdental cleaner in real time. Through the movement trajectory collected during the first operation of the interdental cleaner, adjust the standard model of the human oral structure to match the user's oral structure, thus completing the construction of the preset oral model.

[0081] By comparing the movement trajectory of the interdental cleaner with the tooth positions in the standard model of the human oral structure, adjust the spacing between the teeth and the positions of the teeth in the oral cavity based on the movement trajectory. Specifically, compare the movement trajectory collected for the first time with the tooth positions in the general oral model. Through the spatial matching of each data point of the movement trajectory with the position relationship of the teeth in the oral model, further calculate the actual distribution and arrangement of the user's teeth, and then adjust the standard model of the human oral structure according to the actual distribution and arrangement of the user's teeth, thus completing the construction of the preset oral model.

[0082] S6. If the movement trajectory does not cover the teeth adjacent to the teeth being cleaned by the interdental cleaner, control the drive component to vibrate at a high frequency.

[0083] Specifically, if it is detected that the movement trajectory does not cover the teeth adjacent to the teeth being cleaned, control the vibrating part to vibrate at a high frequency to prompt the user that the interdental cleaner has passed over the teeth adjacent to the teeth being cleaned, so as to avoid missing teeth from being cleaned.

[0084] Furthermore, if the movement trajectory has covered the teeth adjacent to the teeth being cleaned by the interdental cleaner, the vibrating part does not give a vibration prompt.

[0085] S7. If the movement trajectory has covered the teeth adjacent to the teeth being cleaned by the interdental cleaner, identify the movement actions of the interdental cleaner using the movement data, and determine whether the teeth have been effectively cleaned based on the movement actions.

[0086] Specifically, when the movement trajectory has covered the teeth adjacent to the teeth being cleaned by the interdental cleaner, the relative position relationship between the interdental cleaner and the gum is used to identify whether the user is performing an action of scraping debris on the teeth. If the gap distance between the interdental cleaner and the gum becomes larger and smaller multiple times within a preset time range, it is determined that the interdental cleaner is performing an action of scraping debris on the teeth.

[0087] Then, by judging the number of times the interdental cleaner extends into or moves out of the gap between the teeth, the number of times the interdental cleaner scrapes debris on the teeth is determined. The difference between the maximum value of the gap distance between the interdental cleaner and the gum and the minimum value of the gap distance between the interdental cleaner and the gum is used to determine the movement stroke of the interdental cleaner. When the number of actions of the interdental cleaner is not less than the preset number of actions, and the movement stroke of the interdental cleaner is not less than the preset movement stroke, it is determined that the teeth are effectively cleaned.

[0088] S8. If the teeth are not effectively cleaned, control the drive assembly to perform high-frequency vibration.

[0089] Specifically, when the number of actions of the interdental cleaner is less than the preset number of actions, and the movement stroke of the interdental cleaner is less than the preset movement stroke, it is determined that the teeth are not effectively cleaned, and the vibrating member performs high-frequency vibration to give a prompt to the user.

[0090] It should be noted that the vibration mode of the vibrating member when the teeth are not effectively cleaned is different from the vibration mode of the vibrating member when the interdental cleaner crosses the teeth adjacent to the teeth being cleaned. In some specific embodiments, when the teeth are not effectively cleaned, the vibration mode of the vibrating member can be three long and one short, and when the interdental cleaner crosses the teeth adjacent to the teeth being cleaned, the vibration mode of the vibrating member can be two long and two short.

[0091] Furthermore, if the teeth are effectively cleaned, the vibrating member does not perform vibration prompt.

[0092] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
