Description

Technical Field

[0001] This utility model relates to the field of oral hygiene appliances, and in particular to a multifunctional electric toothbrush with a cleaning head. Background Technology

[0002] As people's awareness of oral hygiene continues to increase, electric toothbrushes have gradually become more popular due to their efficient cleaning ability. Most existing electric toothbrushes are mainly designed for cleaning the tooth surface, removing plaque and food debris from the tooth surface through the vibration or rotation of the brush head.

[0003] However, in actual use, simply cleaning the surface of teeth is often insufficient. Bacteria and residue can easily accumulate in the gaps between teeth and on the surface of the tongue. Currently, most electric toothbrushes on the market have relatively limited functions, making it difficult to effectively clean the narrow gaps between teeth, and most do not integrate a dedicated cleaning mechanism for the tongue. To achieve comprehensive oral hygiene, users often need to use additional tools such as dental floss, interdental brushes, and tongue scrapers. This not only increases the complexity of the process but also reduces the convenience and efficiency of daily oral care.

[0004] Therefore, this utility model proposes a multi-functional cleaning head electric toothbrush to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems of existing electric toothbrushes, such as limited cleaning functions, difficulty in cleaning between teeth, and lack of integrated tongue cleaning structure, resulting in incomplete oral cleaning and inconvenience, this utility model aims to provide a multi-functional electric toothbrush with an improved structure, integrating multiple cleaning modes, and effectively solving the above problems.

[0006] This utility model provides a multi-functional electric toothbrush with a cleaning head, including: a charging base, a connecting assembly, and a cleaning component detachably mounted on the connecting assembly. The connecting assembly includes a cylindrical mounting shell and a connecting toothbrush holder fixedly connected to the end of the cylindrical mounting shell.

[0007] The cylindrical mounting housing houses a miniature electric actuator, the output end of which is fixedly connected to a transmission wedge rod. The toothbrush holder has a cylindrical mounting cavity inside, within which a button rod and a mounting rod are slidably arranged axially. One end of the transmission wedge rod is fixedly connected to the button rod, and the end of the button rod away from the transmission wedge rod abuts against the mounting rod. A conical plate is located at the end of the mounting rod away from the button rod. The miniature electric actuator drives the transmission wedge rod and the button rod to push the mounting rod axially along the cylindrical mounting cavity, causing the conical plate to extend out of the toothbrush holder for operation.

[0008] Preferably, to ensure the radial stability of the component connection, one end of the cylindrical mounting shell connecting to the toothbrush holder has a circular boss, the upper end face of which is fixedly fitted with a connecting rod, and the outer circumferential surface of the circular boss has an arc-shaped limiting strip. Correspondingly, the end of the toothbrush holder connecting to the toothbrush holder has a insertion hole at the position of the connecting rod, and the inner wall of the toothbrush holder connecting to the toothbrush holder has an arc-shaped limiting groove that fits into the arc-shaped limiting strip. The cooperation between the arc-shaped limiting strip and the arc-shaped limiting groove prevents relative rotation of the connection.

[0009] Preferably, to ensure the smoothness and accuracy of the movement of the internal transmission rods, a suspension slide sleeve is also fixedly installed inside the cylindrical mounting cavity. The transmission wedge rod, button rod, and mounting rod are all slidably inserted inside the suspension slide sleeve, and the inner wall of the suspension slide sleeve slides against the outer wall of the transmission wedge rod, button rod, and mounting rod, thereby guiding and limiting the movement trajectory of the above components.

[0010] Preferably, to achieve automatic retraction of the extended structure, a spring is fitted around the outer periphery of the mounting rod. An annular retaining ring is provided on the outer wall of the mounting rod, with one end of the spring abutting against the annular retaining ring and the other end abutting against the end face of the suspension slide sleeve, utilizing the elastic potential energy of the spring to assist the mounting rod in retraction.

[0011] Preferably, to facilitate the fixing and replacement of the cleaning components, the cleaning components include a replaceable toothbrush head and a limiting block. The replaceable toothbrush head is inserted into the end of the connecting toothbrush holder away from the cylindrical mounting shell. A U-shaped groove is formed on the lower surface of the middle part of the connecting toothbrush holder, and the limiting block is embedded in the inside of the U-shaped groove, achieving a stable installation through the engagement of the groove.

[0012] Preferably, in order to enhance the tongue cleaning function, a circular arc rubber block is fixedly provided on the surface of the limiting block, and multiple grooves are opened on the surface of the circular arc rubber block. This structure can fit the surface of the tongue and scrape off the tongue coating through the grooves.

[0013] Preferably, in order to facilitate the installation of the interdental cleaning component, the left and right sides of the end of the mounting rod away from the button rod are provided with connecting slots. The conical plate is fixed inside the connecting slots and can move with the mounting rod to the interdental cleaning station for high-frequency vibration.

[0014] Preferably, in order to achieve convenient human-machine interaction control, a control button group is provided on the outside of the cylindrical mounting shell. The control button group is electrically connected to the miniature electric actuator and is used to control the start, stop and reversing operation of the miniature electric actuator.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model solves the problem that existing ordinary electric toothbrush bristles cannot penetrate deep into the gaps between teeth to thoroughly remove impurities by setting a telescopic transmission mechanism consisting of a transmission wedge rod, a button rod, and a mounting rod driven by a miniature electric push rod inside the toothbrush holder, and cooperating with the guiding function of the suspension slide sleeve and the reset function of the spring. It achieves the technical effect that the tooth gap cleaning component can automatically extend and retract according to user needs, accurately position itself, deeply clean the gaps between teeth using high-frequency vibration, and automatically retract to protect the component when not in use.

[0017] 2. This utility model solves the problem of unstable connection or internal transmission misalignment caused by radial relative rotation during the assembly or use of split electric toothbrushes by setting an arc-shaped limiting strip on the circular boss at the end of the cylindrical mounting shell and forming a tight fit with the arc-shaped limiting groove on the inner wall of the toothbrush holder. It achieves the technical effect of high connection stability, accurate radial limiting, and effective guarantee of smooth operation of the internal precision transmission chain.

[0018] 3. This utility model solves the problem of traditional electric toothbrushes having a single function and lacking a targeted tongue cleaning structure by integrating a grooved arc rubber block on the surface of the limiting block of the fixed cleaning component. It achieves the technical effect of using the arc shape to fit the characteristics of the human tongue, increasing friction through the groove to effectively scrape off the tongue coating, and achieving all-round oral cleaning.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please refer to Figures 1 to 5 This utility model provides a multi-functional electric toothbrush with a cleaning head, which aims to solve the structural defects of existing electric toothbrushes that have only one function, can only clean the surface of teeth and cannot effectively clean the gaps between teeth and clean the tongue coating, resulting in incomplete oral cleaning.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, the multi-functional cleaning head electric toothbrush mainly includes a charging base 1, a connecting component 2, and a cleaning component 3 detachably mounted on the connecting component 2. The charging base 1 provides power to the device. The connecting component 2 serves as the core support and transmission structure, including a cylindrical mounting shell 201 and a connecting toothbrush holder 215 fixedly connected to the end of the cylindrical mounting shell 201. A miniature electric push rod 204 is fixedly installed inside the cylindrical mounting shell 201. A transmission wedge rod 209 is fixedly connected to the output end of the miniature electric push rod 204. A cylindrical mounting cavity 207 is formed along the length direction inside the connecting toothbrush holder 215. Inside the mounting cavity 207, a button rod 210 and a mounting rod 211 are slidably arranged along the axial direction. The transmission wedge rod 209 is fixed to the end of the button rod 210 through its own groove structure. The end of the button rod 210 away from the transmission wedge rod 209 abuts against the end face of the mounting rod 211. The end of the mounting rod 211 away from the button rod 210 is provided with a conical plate 213. During operation, the miniature electric push rod 204 drives the transmission wedge rod 209 and the button rod 210 to push the mounting rod 211 to slide outward along the axial direction of the cylindrical mounting cavity 207, causing the conical plate 213 to extend outward from the toothbrush holder 215 to vibrate and clean the gaps between teeth.

[0029] The cylindrical mounting shell 201 is integrally formed with a circular boss 202 at one end of the toothbrush holder 215. An arc-shaped limiting strip 203 protrudes from the outer circumferential surface of the circular boss 202. A connecting rod 205 is fixedly mounted on the upper end of the circular boss 202. An arc-shaped limiting groove 206 with a shape and size matching the arc-shaped limiting strip 203 is opened on the inner wall of the corresponding end of the toothbrush holder 215. When the cylindrical mounting shell 201 and the toothbrush holder 215 are assembled together, the connecting rod 205 is inserted into the corresponding mating hole at the end of the toothbrush holder 215 to achieve precise axial alignment. The arc-shaped limiting strip 203 is tightly fitted into the arc-shaped limiting groove 206. This fitting structure of the protrusion and the groove effectively restricts the radial relative rotation between the two and ensures a stable connection.

[0030] To ensure smooth movement of the slender internal rods, a hovering slide sleeve 208 is fixedly installed inside the cylindrical mounting cavity 207. The center of the hovering slide sleeve 208 has a through guide hole. The transmission wedge rod 209, button rod 210, and mounting rod 211 are sequentially inserted and slidably fitted in the guide hole. The hovering slide sleeve 208 provides precise guidance and limit for the reciprocating movement of the transmission wedge rod 209, button rod 210, and mounting rod 211. In addition, a spring 214 is sleeved on the outer periphery of the mounting rod 211. The surface of the mounting rod 211 has an annular protrusion. The two ends of the spring 214 abut against the annular protrusion and the end face of the hovering slide sleeve 208, respectively. The elastic deformation of the spring 214 provides auxiliary power for the reset movement of the mounting rod 211.

[0031] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0032] In a preferred embodiment, to facilitate the replacement of worn parts and ensure connection stability, the cleaning component 3 includes a replaceable toothbrush head 301 and a limiting block 303. The replaceable toothbrush head 301 is inserted into the end of the connecting toothbrush holder 215 away from the cylindrical mounting shell 201. A U-shaped groove 302 is formed on the lower surface of the middle part of the connecting toothbrush holder 215. The limiting block 303 is embedded in the U-shaped groove 302. The U-shaped groove 302 and the limiting block 303 cooperate to limit the position of the limiting block 303, thereby fixing the cleaning component 3.

[0033] As a preferred embodiment, in order to enhance the tongue cleaning function, a circular arc rubber block 304 is fixedly provided on the surface of the limiting block 303. Multiple grooves 305 are opened on the surface of the circular arc rubber block 304. The shape of the circular arc rubber block 304 is designed to fit the structure of the human tongue. The grooves 305 are used to increase friction to scrape off the tongue coating.

[0034] In a preferred embodiment, in order to achieve the assembly and transmission of the interdental cleaning structure, connecting slots 212 are respectively opened on the left and right sides of the end of the mounting rod 211 away from the button rod 210. The conical plate 213 is snapped and fixed inside the connecting slots 212. The conical plate 213 moves axially with the mounting rod 211 and transmits vibration.

[0035] As a preferred embodiment, in order to realize human-machine interaction control of the internal power source, a control button group 4 is installed on the outer wall of the cylindrical mounting shell 201. The control button group 4 is electrically connected to the miniature electric push rod 204 through wires and is used to control the start, stop and reversal of the miniature electric push rod 204.

[0036] The working principle of this multi-functional cleaning head electric toothbrush is as follows:

[0037] During the device assembly stage, the operator aligns the connecting toothbrush holder 215 in the connecting assembly 2 with the end of the cylindrical mounting shell 201 near the circular boss 202. At this time, the arc-shaped limiting strip 203 at the end of the cylindrical mounting shell 201 slides into the arc-shaped limiting groove 206 inside the connecting toothbrush holder 215. The interlocking of the two achieves radial limiting to prevent relative rotation during subsequent use. At the same time, the connecting rod 205 is inserted into the mating hole at the end of the connecting toothbrush holder 215 to ensure that the axis of the cylindrical mounting cavity 207 is aligned. Then, the replaceable toothbrush head 301 is inserted into the top of the connecting toothbrush holder 215, and the limiting block 303 is embedded in the U-shaped slot 302 to complete the fixing of the cleaning assembly 3.

[0038] During routine cleaning, the user holds the device and uses the replaceable toothbrush head 301 to brush the tooth surface. When it is necessary to clean deep between the teeth, the user presses the control button group 4 to issue a command. The miniature electric push rod 204 inside the cylindrical mounting shell 201 is activated and its output end is extended, pushing the transmission wedge rod 209 to move axially along the cylindrical mounting cavity 207. The transmission wedge rod 209 drives the button rod 210 that is fitted with it to move forward synchronously. The button rod 210 then pushes the mounting rod 211 to slide outward to the toothbrush holder 215. During this process, the suspension slide sleeve 208 restricts the radial displacement of the transmission wedge rod 209, the button rod 210 and the mounting rod 211 to ensure a smooth movement trajectory. At the same time, the mounting rod 211 pushes the spring 214 to generate compression deformation. When the mounting rod 211 moves to the limit position, the conical plate 213 that is locked in the connecting slot 212 extends to the working position, and in conjunction with high-frequency vibration, it vibrates and removes impurities inside the gaps between the teeth.

[0039] After cleaning, the user operates the control button group 4 again, the micro electric push rod 204 retracts in the reverse direction, the spring 214 releases elastic potential energy to push the mounting rod 211 to reset in the reverse direction, thereby driving the button rod 210 and the transmission wedge rod 209 back to the initial position, the conical plate 213 retracts into the toothbrush holder 215. For tongue cleaning, the user flips the device to use the arc rubber block 304 on the limit block 303 to fit against the tongue surface, and removes the tongue coating through the scraping action of the groove 305.

[0040] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
