[0033] In order to illustrate the technical solution described in this application, a detailed description is given below in conjunction with specific drawings and embodiments.

[0034] like Figures 1 to 4As shown, one embodiment of the present application provides a disinfecting toothbrush, including a brush rod 20, a handle and a disinfecting structure 60. A brush head 10 is provided at one end of the brush rod 20, and the other end of the brush rod 20 is rotatably connected to the handle. The handle is provided with a receiving cavity and a first receiving groove 421, the receiving cavity is used to receive toothpaste 1, and the first receiving groove 421 is used to receive the brush head 10. The brush rod 20 can rotate relative to the handle to drive the brush head 10 to extend into or move out of the first receiving groove 421. The disinfecting structure 60 is installed on the brush rod 20, the brush head 10 or the handle.

[0035] Compared with the related art, the disinfecting toothbrush of the embodiment of the present application has a self-contained disinfecting function by directly installing the disinfecting structure 60 on the brush rod 20, the brush head 10 or the handle. Since the handle is provided with a receiving cavity for accommodating toothpaste 1, the toothpaste 1 can be placed in the receiving cavity, so that the toothpaste 1 and the disinfecting toothbrush can be carried together, which saves storage space and is easy to carry. In addition, since the handle is also provided with a first receiving groove 421 for accommodating the brush head 10, on the one hand, it can reduce the contact of external bacteria and impurities with the brush head 10, and on the other hand, the internal space of the handle is used to accommodate the brush head 10. When the brush head 10 is not needed, the brush rod 20 can be rotated so that the brush head 10 is stored in the first receiving groove 421, which further saves storage space.

[0036] In summary, the disinfecting toothbrush provided in the embodiment of the present application has its own disinfection function, saves more storage space, and is easy to carry.

[0037] In the embodiment of the present application, the toothpaste 1 contained in the containing cavity can be solid toothpaste, paste toothpaste or liquid toothpaste, etc., which is not limited here.

[0038] In the embodiment of the present application, the disinfection structure 60 can be a structure such as an ultraviolet disinfection structure, a heating structure, a drying structure or a disinfectant release structure that can be used to disinfect the brush head 10. When the disinfection structure 60 is an ultraviolet disinfection structure, for example, when the disinfection structure 60 is an ultraviolet disinfection lamp, ultraviolet light can be emitted to the brush head 10 by the ultraviolet disinfection lamp to sterilize and disinfect the brush head 10. When the disinfection structure 60 is a heating structure, the brush head 10 is heated by the heating structure to sterilize and disinfect the brush head 10. When the disinfection structure 60 is a drying structure, the brush head 10 can be dried by the drying structure to sterilize and disinfect the brush head 10, and at the same time, the growth of bacteria can be effectively reduced. When the disinfection structure 60 is a disinfectant release structure, specifically, the disinfection structure 60 can be an ozone disinfection structure, and ozone is released to the brush head 10 by the ozone disinfection structure to sterilize and disinfect the brush head 10.

[0039] Optionally, there may be multiple disinfection structures 60, and the multiple disinfection structures 60 are respectively opposite to different side walls of the first receiving groove 421. In this way, the brush head 10 located in the first receiving groove 421 can be disinfected in multiple directions, and the disinfection effect is better. The disinfection structures 60 can be of the same structure or of different structures, which is not limited here.

[0040] In a possible design, the handle includes a first handle 30 and a second handle 40, one end of the first handle 30 and the second handle 40 are detachably connected, and the other end of the first handle 30 is rotatably connected to the brush rod 20. The first storage groove 421 is arranged on the second handle 40, and the disinfection structure 60 is installed on the second handle 40, and the disinfection structure 60 is opposite to the first storage groove 421. In this way, in practical applications, different second handles 40 can be replaced according to actual needs. It is worth noting that different second handles 40 specifically refer to second handles 40 with different types of installed disinfection structures 60. For example, the second handle 40 equipped with an ozone disinfection structure 60 can be replaced with a second handle 40 equipped with an ultraviolet disinfection lamp. It can be seen from this that the disinfection method that can be selected by the disinfection toothbrush provided in the embodiment of the present application is more diverse, so that users can choose different disinfection methods to disinfect the brush head 10 according to their preferences.

[0041] In one example, the disinfection structure 60 is an ultraviolet disinfection lamp, such as Figure 4 As shown, the ultraviolet disinfection lamp is installed in the second handle 40, and the ultraviolet disinfection lamp is opposite to the first storage groove 421. When the brush head 10 is located in the first storage groove 421, the brush head 10 can be disinfected by the ultraviolet disinfection lamp. Optionally, at least one side wall of the first storage groove 421 is provided with a light-transmitting glass, and the ultraviolet disinfection lamp is installed on the side of the light-transmitting glass away from the first storage groove 421. The ultraviolet light emitted by the ultraviolet disinfection lamp can be projected into the first storage groove 421 through the light-transmitting glass, thereby sterilizing the brush head 10 located in the first storage groove 421.

[0042] In some embodiments, the first handle 30 and the second handle 40 can be detachably connected by plugging, snapping or screwing. Optionally, the first handle 30 and the second handle 40 can be detachably connected by plugging. Figure 4As shown, the first handle 30 has an inner cavity 31, and the second handle 40 includes a first section 41 and a second section 42 connected to each other; the first section 41 has a second receiving groove 411 for accommodating toothpaste 1, the first section 41 is inserted in the inner cavity 31, the second section 42 covers the opening of the inner cavity 31, and the second section 42 and the inner wall of the inner cavity 31 are surrounded to form an accommodating cavity; the first receiving groove 421 is arranged on the outer side of the second section 42. Since the first section 41 is inserted in the inner cavity 31, and the first section 41 has the second receiving groove 411 for accommodating toothpaste 1, in the process of pulling out the first section 41, the toothpaste 1 in the second receiving groove 411 can be moved out of the inner cavity 31, so that it is convenient for users to take the toothpaste 1. Optionally, the ultraviolet disinfection lamp is specifically installed in the second section 42.

[0043] In a possible design, the brush head 10 is detachably connected to the brush rod 20. With such a configuration, in actual use, it is only necessary to regularly replace the brush head 10, which saves the use cost to a certain extent. Moreover, in such a configuration, brush heads 10 of various sizes can be designed, so that users can replace brush heads 10 of different sizes according to actual needs.

[0044] In some optional embodiments, the size of the first receiving groove 421 on the second handle 40 matches the size of the brush head 10, that is, a variety of second handles 40 can be designed, and the sizes of the first receiving grooves 421 on different types of second handles 40 are different. When the brush head 10 on the brush rod 20 is an S-size (small-size) brush head 10, the second handle 40 connected to the first handle 30 can be replaced with a second handle 40 provided with an S-size first receiving groove 421; when the brush head 10 on the brush rod 20 is replaced with an L-size (large-size) brush head 10, the second handle 40 connected to the first handle 30 can be replaced with a second handle 40 provided with an L-size first receiving groove 421. In this way, the diversity and versatility of the disinfecting toothbrush are effectively improved.

[0045] In a possible design, the disinfecting toothbrush also includes a controller, a detection structure is provided in the handle, the detection structure is opposite to the first receiving slot 421, and the detection structure and the disinfection structure 60 are respectively connected to the controller signal; the detection structure is used to detect whether the brush head 10 is accommodated in the first receiving slot 421, and the detection result is fed back to the controller; the controller is used to control the working state of the disinfection structure 60 according to the detection result. It is worth noting that in the embodiment of the present application, the signal connection is specifically a connection that can realize data signal transmission, and the signal connection can be a wired connection or a wireless connection. It is worth noting that the working state of the disinfection structure 60 mainly includes a disinfection state and a standby state. The controller is specifically used to control the disinfection structure 60 to switch to a disinfection state or a standby state according to the detection structure.

[0046] In this arrangement, by setting up a controller and a detection structure, the disinfecting toothbrush can automatically identify whether the brush head 10 is located in the first storage slot 421. When the detection structure detects that the brush head 10 is accommodated in the first storage slot 421, the controller controls the disinfection structure 60 to switch to the disinfection state, so that the disinfection structure 60 disinfects the brush head 10, thereby realizing the automatic disinfection function; when the detection structure detects that the brush head 10 is not accommodated in the first storage slot 421, the controller controls the disinfection structure 60 to switch to the standby state to reduce energy consumption.

[0047] Optionally, the detection structure includes a photoelectric sensor, an infrared sensor or other structures that can be used to detect the position of an object, which is not limited here.

[0048] In one example, when the handle includes a first handle 30 and a second handle 40, and the first receiving groove 421 is disposed on the second handle 40, the detection structure is specifically disposed in the second handle 40 so that the detection structure can detect whether the brush head 10 is accommodated in the first receiving groove 421.

[0049] In some optional embodiments, the controller may be disposed in the handle, or in the brush rod 20, or in other structures of the disinfecting toothbrush.

[0050] Specifically, the controller and the detection structure are both disposed in the second section 42 of the second handle 40. In some optional embodiments, such as Figure 4 As shown, the second section 42 has an installation cavity 424, a circuit board 70 is arranged in the installation cavity 424, and the disinfection structure 60, the detection structure and the controller are all installed in the installation cavity 424, and the disinfection structure 60, the detection structure and the controller are all connected to the circuit board 70 by signal. It is worth noting that the disinfection structure 60, the detection structure and the controller are all connected to the circuit board 70 by wired signals.

[0051] Optionally, a battery 80 is further provided in the installation cavity 424, and the battery 80 is electrically connected to the circuit board 70. The disinfection structure 60, the detection structure and the controller are electrically connected to the battery 80 through the circuit board 70. Optionally, the second section 42 is further provided with a charging interface 90, and the charging interface 90 is electrically connected to the circuit board 70, and the charging port is provided to facilitate charging the battery 80.

[0052] In one possible design, Figure 5 and Figure 6 As shown, a first limiting structure 422 is provided in the first receiving groove 421, and a second limiting structure 11 is provided in the brush head 10. When the brush head 10 is located in the first receiving groove 421, the first limiting structure 422 and the second limiting structure 11 are connected to each other. In this way, the brush head 10 can be more stably received in the first receiving groove 421, thereby providing better protection for the brush head 10.

[0053] In some optional embodiments, the first limiting structure 422 and the second limiting structure 11 may be two magnets with opposite magnetic properties. When the brush head 10 is located in the first receiving groove 421, the first limiting structure 422 and the second limiting structure 11 attract and fit each other, so that the brush head 10 is stably received in the first receiving groove 421.

[0054] In a possible design, one of the first limiting structure 422 and the second limiting structure 11 includes a limiting block, and the other includes a limiting groove. When the brush head 10 is located in the first receiving groove 421, the limiting block and the limiting groove are plugged into each other. In this arrangement, the brush head 10 is more stably received in the first receiving groove 421 through the cooperation of the limiting groove and the limiting block. It is worth noting that in this arrangement, the length of the limiting block inserted into the limiting groove is relatively short. In this way, when the brush head 10 extends into the first receiving groove 421, the limiting block can be inserted into the limiting groove by squeezing the limiting block so that the limiting block undergoes a certain elastic deformation. That is to say, when the brush head 10 is extended into the first receiving groove 421, the limit block is squeezed by the brush head 10 and the inner wall of the first receiving groove 421, so that the limit block undergoes elastic deformation. When the limit block is opposite to the limit groove, the limit block returns to the state before the elastic deformation, so that the limit block is inserted into the limit groove.

[0055] Optional, such as Figures 4 to 6 As shown, the first limiting structure 422 includes a limiting block, and the second limiting structure 11 includes a limiting groove. The limiting block is protrudingly arranged on the inner wall of the first receiving groove 421, and the limiting groove is opened on the outer side of the brush head 10. For the convenience of description, the following description is based on the example that the first limiting structure 422 includes a limiting block and the second limiting structure 11 includes a limiting groove.

[0056] In a possible design, the first limiting structure 422 is arranged on the inner wall of the first receiving groove 421 away from the first handle 30. Since the second section 42 moves away from the first handle 30 during the process of pulling out the first section 41 from the inner cavity 31, the first limiting structure 422 is arranged on the inner wall of the first receiving groove 421 away from the first handle 30, so that the first limiting structure 422 can be moved away from the second limiting structure 11 during the process of pulling out the first section 41, thereby separating the first limiting structure 422 from the second limiting structure 11. In this way, the user can release the limit of the brush head 10 in the first receiving groove 421 during the process of pulling out the first section 41 to take out the toothpaste 1, so that the brush head 10 can be removed from the first receiving groove 421 for brushing teeth.

[0057] In one possible design, Figure 3 and Figure 7As shown, an elastic reset structure 50 is provided between the brush rod 20 and the first handle 30, and the elastic reset structure 50 is connected to the brush rod 20 and the first handle 30 respectively. The elastic reset structure 50 is used to rotate the brush rod 20 relative to the first handle 30 to drive the brush head 10 to move out of the first receiving groove 421. In this way, when the first limiting structure 422 and the second limiting structure 11 are separated, the brush head 10 can automatically move out of the first receiving groove 421 under the action of the elastic reset structure 50, and the operation is more convenient.

[0058] In some optional embodiments, the elastic reset structure 50 includes a torsion spring, which is connected to the brush rod 20 and the first handle 30 respectively.

[0059] In some other optional embodiments, Figure 7 and Figure 8 As shown, two bases 32 are arranged at intervals at one end of the first handle 30 connected to the brush rod 20. The elastic reset structure 50 includes a rotating shaft 51, a spring 52, a first connecting member 53, a second connecting member 54 and a sliding member 55. The first connecting member 53 is fixedly mounted on one of the bases 32, and the second connecting member 54 is mounted on the other base 32. A through hole is arranged at one end of the brush rod 20 connected to the first handle 30, and the rotating shaft 51 is penetrated through the through hole, and the two ends of the rotating shaft 51 are rotatably connected to the first connecting member 53 and the second connecting member 54 respectively. The spring 52 and the sliding member 55 are both sleeved on the rotating shaft 51, and the sliding member 55 is located between the spring 52 and the first connecting member 53. A convex strip is arranged on the inner wall of the through hole, and a sliding groove is arranged on the sliding member 55, and the boss is located in the sliding groove. When the brush rod 20 rotates, the sliding member 55 can be driven to rotate synchronously. A first mating surface 531 is arranged on the side of the first connecting member 53 facing the sliding member 55, and the sliding member 55 abuts on the first mating surface 531. The sliding member has a second mating surface 551 on one side facing the first connecting member 53. The first mating surface 531 and the second mating surface 551 are both arranged at an angle to the axis of the rotating shaft 51. In the initial position, Figure 1 and Figure 8 As shown, when the length direction of the brush rod 20 is parallel to the length direction of the first handle 30 and the brush head 10 is located outside the first receiving groove 421 , the first mating surface 531 and the second mating surface 551 are completely fitted.

[0060] When storing disinfected toothbrushes, Figure 2 and Fig. 9As shown, the first section 41 can be partially inserted into the inner cavity 31. Then the brush rod 20 is rotated relative to the first handle 30 around the axis of the rotating shaft 51, and the sliding member 55 is driven to rotate relative to the first connecting member 53, and the sliding member moves along the first mating surface 531, so that the first mating surface 531 and the second mating surface 551 are gradually staggered, and the sliding member gradually moves away from the first connecting member 53 to the direction close to the second connecting member 54, and the spring 52 is compressed by the sliding member 55 and the second connecting member 54 and accumulates force. In the process of the brush rod 20 rotating from the initial position relative to the first handle 30, the brush head 10 is gradually approached by the brush rod 20 until it extends into the first receiving groove 421, and the limit block and the limit groove are opposite. Finally, the second section 42 is pushed in the direction close to the first section 41, so that the first section 41 is completely inserted into the inner cavity 31, and the limit block is inserted into the limit groove, so that the brush head 10 is stably received in the first receiving groove 421. The detection structure in the second section 42 detects that the brush head 10 is accommodated in the first receiving groove 421 , so that the controller controls the disinfection structure 60 to switch to the disinfection state to disinfect the brush head 10 .

[0061] When the disinfected toothbrush needs to be used, the second section 42 only needs to be pulled away from the first handle 30 to move the limit block out of the limit groove. The spring 52 in the elastic reset structure 50 rebounds and pushes the sliding member 55 close to the first connecting member 53, so that the sliding member moves along the first mating surface 531. In the process of the sliding member moving along the first mating surface 531, the sliding member also rotates around the axis of the rotating shaft 51, that is, the sliding member 55 can rotate around the axis of the rotating shaft 51 while approaching the first connecting member 53 under the push of the spring 52, thereby driving the brush rod 20 to rotate around the axis of the rotating shaft 51, so that the brush rod 20 returns to the initial position.

[0062] In one possible design, the first limiting structure 422 includes a limiting block, the second limiting structure 11 includes a limiting groove, and a button is provided on the second handle 40. The button is transmission-connected to the limiting block, and the button can move relative to the second handle 40 to drive the limiting block to move out of or extend into the limiting groove.

[0063] Exemplarily, the button is movably mounted on the second section 42 of the second handle 40. When the brush head 10 is located in the first receiving groove 421 and the limit block is inserted in the limit groove, the limit block can be driven to move out of the limit groove by pressing the button, so that the brush rod 20 returns to the initial position under the action of the elastic reset structure 50, and the brush head 10 is driven by the brush rod 20 to move out of the first receiving groove 421.

[0064] In a possible design, a protrusion structure is provided at one end of the first section 41 close to the second section 42, and the protrusion structure abuts against the inner wall of the inner cavity 31. In this arrangement, the friction between the protrusion structure and the inner wall can improve the stability of the first section 41 inserted into the inner cavity 31.

[0065] In some embodiments, the protrusion structure may include a plurality of convex hulls, which are arranged at intervals around the circumference of the first segment 41 and on the surface of the first segment 41. When the first segment 41 is completely inserted into the inner cavity 31, each convex hull abuts against the inner wall of the inner cavity 31.

[0066] In other embodiments, the protruding structure includes a sealing ring 412, which is disposed around the outer periphery of the first section 41 and abuts against the inner wall of the inner cavity 31. In this arrangement, the sealing ring 412 abuts against the inner wall of the inner cavity 31, which not only improves the stability of the first section 41 inserted into the inner cavity 31, but also improves the sealing of the accommodating cavity, so that the toothpaste 1 can be better preserved. Optionally, the sealing ring 412 can be made of rubber, plastic or other flexible materials.

[0067] In a possible design, the first handle 30 is provided with a third storage groove 33, and the brush rod 20 can be rotated and placed in the third storage groove 33. In this arrangement, by providing the third storage groove 33, at least part of the structure of the brush rod 20 is located in the third storage groove 33, so that the storage space occupied by the disinfecting toothbrush can be further reduced, making it more convenient to carry.

[0068] In some examples, when the brush head 10 is located in the first receiving groove 421, the length direction of the brush rod 20 is parallel to the length direction of the first handle 30. The opening direction of the third receiving groove 33 is the same as the opening direction of the first receiving groove 421, and the third receiving groove 33 penetrates the first handle 30 along the length direction of the first handle 30. The second section 42 is provided with a connecting groove 423 on one side of the first receiving groove 421. The connecting groove 423 is located between the first receiving groove 421 and the third receiving groove 33, and the first receiving groove 421 and the third receiving groove 33 are connected through the connecting groove 423. In this way, when the brush rod 20 is rotated relative to the first handle 30 so that the brush head 10 is located in the first receiving groove 421, the brush rod 20 can also be located in the third receiving groove 33 and the connecting groove 423 respectively.

[0069] The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
