People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] An oral cleaner, combined Figures 1 to 3 , including a handheld part 1, a driving device and a full-cover brush head 9.

[0033] A driving device is arranged on one side of the hand-held portion 1, and the full-covered brush head 9 is connected to the driving device. The driving device is used to drive the full-covered brush head 9 to swing back and forth. A lip wrapping portion is arranged on the hand-held portion 1 close to the full-covered brush head 9. The lip wrapping portion includes an inner lip shielding portion 11 and an outer lip shielding portion 12. The inner lip shielding portion 11 and the outer lip shielding portion 12 are both flexible annular sheets, which can be specifically made of food-grade silicone. An annular lip embedding area 13 is formed between the inner lip shielding portion 11 and the outer lip shielding portion 12. A guide tube 14 is arranged in the hand-held portion 1. The guide tube 14 passes through the hand-held portion 1 from the side close to the full-covered brush head 9 to the side away from the full-covered brush head 9. It should be noted that the guide tube 14 passes through the hand-held portion 1 and also passes through the lip wrapping portion on the hand-held portion 1.

[0034] When in use, put the full-cover brush head 9 into the mouth, embed the teeth into the full-cover brush head through the biting action, embed the human lips into the annular lip embedding area 13, and drive the full-cover brush head 9 to swing back and forth in the direction of tooth arrangement through the driving device to clean the teeth. The lip wrapping part can prevent the liquid in the oral cavity from flowing out. Therefore, the oral cleaner can be used in the weightlessness of space. The guide tube 14 is used for liquid to flow into or out of the oral cavity. The end of the guide tube 14 away from the full-cover brush head 9 can be connected to a flexible tube to collect liquid flowing out of the oral cavity or inject liquid into the oral cavity. It is more convenient to use both in daily use and in the weightlessness of space.

[0035] The hand-held portion 1 is a hollow structure, and the lip wrapping portion is arranged on the side of one end of the hand-held portion 1. When in use, the hand-held portion 1 can be held by hand to perform the teeth brushing process.

[0036] Combination Figure 3 and Figure 4 The driving device includes a battery 2, a reduction motor 3, a ball head eccentric shaft 4, a vertical track 5, a swing bracket 6 and a fixed bracket 7. The battery 2 can be a dry cell 2 or a storage battery 2. The battery 2 is fixedly arranged in the handheld part 1. A cover plate for convenient disassembly and replacement of the battery 2 can be arranged on the outer wall of the handheld part 1. The reduction motor 3 is fixedly arranged in the handheld part 1. The shaft of the reduction motor 3 passes through the outer wall of the handheld part 1. The shaft of the reduction motor 3 is located at the center of the lip wrapping part. The reduction motor 3 is electrically connected to the battery 2. A control switch 8 is arranged between the reduction motor 3 and the battery 2. The control switch 8 can be fixed on the outer wall of the handheld part 1. After the circuit between the battery 2 and the reduction motor 3 is connected by the control switch 8, the motor can be operated.

[0037] One end of the ball head eccentric shaft 4 is fixedly connected to the shaft of the reduction motor 3, and the other end is provided with a ball head. The vertical track 5 is an annular structure, and the middle part is a long strip hole. One end of the ball head of the ball head eccentric shaft 4 is slidably connected to the vertical track 5. The vertical track 5 is fixedly connected to one end of the swing bracket 6. Two mounting holes 15 are provided on the side wall of the handheld part 1. Two plug connectors 71 are provided at one end of the fixed bracket 7. The plug connector 71 of the fixed bracket 7 is inserted into the mounting hole 15 and fixedly connected to the handheld part 1. The end of the swing bracket 6 away from the vertical track 5 is rotatably connected to the end of the fixed bracket 7 away from the handheld part 1 through the pin shaft 61. The axial direction of the pin shaft 61 is not parallel to the track direction of the vertical track 5. The fixed bracket 7 can provide stable support for the swing bracket 6. A card interface 91 is provided on the full-cover brush head 9. The swing bracket 6 is inserted into the card interface 91 and is fixedly connected to the full-cover brush head 9.

[0038] When the reduction motor 3 is running, it drives the ball head eccentric shaft 4 to rotate. The lateral displacement of one end of the ball head of the ball head eccentric shaft 4 drives the vertical track 5 to swing horizontally, and the longitudinal displacement of the ball head eccentric shaft 4 slides along the vertical track 5. Therefore, when the ball head eccentric shaft 4 rotates, it can drive the vertical track 5 to swing back and forth horizontally, and then drive the full-cover brush head 9 to swing back and forth through the swing bracket 6 to realize the brushing action.

[0039] To facilitate the connection between the swing bracket 6, the fixed bracket 7 and the full-covered brush head 9, a circular hole 62 is provided on the swing bracket 6. One end of the fixed bracket 7 passes through the circular hole 62 and is connected to the swing bracket 6 through a pin shaft 61. The width of the circular hole 62 is larger than the width of the part of the fixed bracket 7 located in the circular hole 62, thereby meeting the swinging requirement of the swing bracket 6. The full-covered brush head 9 is connected to the outer wall of the circular hole 62 to prevent the full-covered brush head 9 from affecting the relative swing between the swing bracket 6 and the fixed bracket 7.

[0040] Combination Figures 5 to 7 The upper and lower sides of the full-cover brush head 9 are respectively provided with bristles 98, so that the upper and lower rows of teeth of the human body can be cleaned at the same time.

[0041] Optionally, the angle between the mounting plane at the root of the upper bristles 98 of the full-covered brush head 9 and the mounting plane at the root of the lower bristles 98 of the full-covered brush head 9 is 10°, which is more suitable for cleaning work when the two rows of teeth are slightly open, and the cleaning is more thorough.

[0042] The full-cover brush head 9 includes a front cleaning section 92, a left middle cleaning section 93, a left end cleaning section 94, a right middle cleaning section 95, and a right end cleaning section 96. The left end of the front cleaning section 92 is connected to the left middle cleaning section 93 and the left end cleaning section 94 in sequence, and the right end of the front cleaning section 92 is connected to the right middle cleaning section 95 and the right end cleaning section 96 in sequence. The adjacent cleaning sections are connected by a hairless flexible connecting rod 97, which can be a part of the base layer for fixing the bristles 98 on the full-cover brush head 9. The front cleaning section 92 is mainly used to clean the front teeth and the surrounding areas of the front teeth of the human body, the left middle cleaning section 93 and the right middle cleaning section 95 are mainly used to clean the canine part of the human body, and the left end cleaning section 94 and the right end cleaning section 96 are mainly used to clean the molar part of the human body. The segmented structure of the full-cover brush head 9 can form a more comprehensive cleaning of the teeth, and because the sections are hairless and flexible connection structures, the angles between the sections are adaptively adjusted in accordance with the direction of the teeth, which is suitable for the tooth structures of different people.

[0043] Combination Figure 8 and Fig. 9 Preferably, two bristle surfaces 98 are provided in the brush groove of the front cleaning section 92. The incisors are smaller in width and slightly tilted forward. The two bristle surfaces 98 have a better cleaning effect on both sides of the incisors, and can also clean the end faces of the incisors. Canines and molars are mainly vertical teeth. The left middle cleaning section 93, the left end cleaning section 94, the right middle cleaning section 95 and the right end cleaning section 96 are provided with three bristle surfaces 98 in the brush grooves, which can have a better cleaning effect on the side walls and end faces of canines and molars.

[0044] Combination Fig.10 and Fig.11 The guide tube 14 is mainly used for the liquid in and out of the oral cavity. To achieve a better effect of liquid in and out, the guide tube 14 is set as a three-way tube, and two guide tubes are set. The guide tube 14 is close to the full-cover brush head 9 and has an inner guide hole 141. The end away from the full-cover brush head 9 is set with an outer guide hole 142. One of them can input liquid into the oral cavity, and the other can output liquid in the oral cavity. The input of clean toothpaste and water is separated from the output of toothpaste, saliva, and water in the oral cavity, which is cleaner and more convenient to use. In order to realize that the two guide tubes 14 can only pass in one direction, a one-way valve can be set on the guide tube 14 or the external pipeline of the guide tube 14.

[0045] The oral cleaner provided in the present application has the advantages of being more convenient, thorough, more comprehensive, and faster in cleaning speed, and can also be used in weightlessness in space.

[0046] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
