[0003] Existing oral hygiene devices have the following drawbacks during use:

[0004] Oral hygiene is typically achieved using a toothbrush, but toothbrushes and toothpaste are used separately, making them inconvenient to carry when going out and taking up storage space for users. Therefore, a new type of oral hygiene device is needed. Utility Model Content

[0005] The purpose of this invention is to provide a novel oral cavity cleaning device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A novel oral cleaning device includes a hollow brush handle, one end of which is fixedly connected to a hollow tail sleeve via a hollow outer sleeve. A hollow rod is fixedly connected to the center of the inner wall of the tail sleeve. A T-shaped portion of the hollow rod, away from the tail sleeve, is fixedly connected to the brush handle, and a brush sleeve is rotatably fitted onto the outer side of the T-shaped portion. The brush sleeve is also rotatably fitted onto the outer side of the brush handle. A plurality of equidistant first paste dispensing holes are opened at the center of the top of the brush sleeve. A paste dispensing component is installed inside the outer sleeve and connected to the hollow rod, the brush handle, and the brush sleeve.

[0008] In a preferred embodiment, a groove is provided at the center of the inner wall of the brush sleeve to mate with the T-shaped portion.

[0009] In a preferred embodiment, an ointment filling tube is fixedly connected to the ointment filling port on the outer side of the tail sleeve, and a sealing cap is threaded to the end of the ointment filling tube.

[0010] In a preferred embodiment, the cream dispensing component includes a second cream dispensing hole disposed directly below a plurality of first cream dispensing holes, the plurality of second cream dispensing holes being disposed on the brush handle, a plurality of third cream dispensing holes disposed on one side of the plurality of second cream dispensing holes, and a plurality of fourth cream dispensing holes disposed on one side of the plurality of third cream dispensing holes, wherein the diameter of the second cream dispensing holes is larger than the diameter of the third cream dispensing holes, and the diameter of the third cream dispensing holes is larger than the diameter of the fourth cream dispensing holes.

[0011] In a preferred embodiment, the inner wall of the outer sleeve is fixed with a plurality of spring pieces arranged in a ring array. The cross-section of the spring pieces is S-shaped. A common synchronizing rod is fixed to a plurality of spring pieces in one row. A U-shaped locking rod is fixed to the bottom end of the synchronizing rod and is movably inserted into the hollow rod.

[0012] In a preferred embodiment, one end of the U-shaped locking rod away from the synchronizing rod extends movably to the outside of the brush handle and is inserted into a locking hole opened in the inner wall of the brush sleeve. There are four locking holes, which are arranged in a ring array on the inner wall of the brush sleeve.

[0013] Compared with the prior art, the novel oral cavity cleaning device provided by this utility model has at least the following beneficial effects:

[0014] In this invention, when using the novel oral cleaning device, toothpaste is stored in the space between the outer sleeve and the hollow rod. When the cleaning device is needed to clean the teeth, the outer sleeve can be squeezed to deform it, and with the help of multiple spring clips, the toothpaste in the aforementioned space will be squeezed out through multiple second toothpaste outlets into multiple first toothpaste outlets, making it convenient for the user to brush their teeth. Furthermore, if the user needs to reduce the amount of toothpaste, they can squeeze the outer sleeve simultaneously, causing the synchronizing rod to move the U-shaped lever downwards, and causing the U-shaped lever to move away from the synchronizing rod... The toothbrush sleeve is pulled out from the corresponding slot. Because four slots are arranged in a circular array, the sleeve can be rotated, allowing it to rotate outside the handle. When multiple first toothpaste outlets coincide with multiple third or fourth toothpaste outlets, the outer sleeve can be released. Under the rebound force of the spring, the end of the U-shaped locking rod away from the synchronizing rod is reinserted into the corresponding slot, thus fixing the sleeve in place. This allows the toothpaste and toothbrush to be used together, reducing the space occupied during carrying, and also makes it easy to lock the rotated sleeve, thus facilitating the adjustment of the amount of toothpaste dispensed according to the user's needs.

[0026] Example

[0027] Oral hygiene is generally achieved using a toothbrush, but toothbrushes and toothpaste are used separately, making them inconvenient to carry when going out and taking up storage space for users.

[0028] For this purpose, please refer to Figure 1-6This utility model provides a novel oral cleaning device, comprising: a hollow brush handle 1, one end of which is fixedly connected to a hollow tail sleeve 12 via a hollow outer sleeve 11, a hollow rod 111 fixedly connected to the center of the inner wall of the tail sleeve 12, a T-shaped portion of the hollow rod 111 away from the tail sleeve 12 fixedly connected to the brush handle 1, and a brush sleeve 14 rotatably sleeved on the outer side of the T-shaped portion, the brush sleeve 14 also rotatably sleeved on the outer side of the brush handle 1, and a plurality of equidistant first paste dispensing holes 141 opened at the center of the top of the brush sleeve 14; and a paste dispensing component 2, which is installed inside the outer sleeve 11 and connected to the hollow rod 111, the brush handle 1, and the brush sleeve 14.

[0029] The cavity formed by the inner sleeve 11, the inner handle 1, the inner tail sleeve 12, and the outer side of the hollow rod 111 is used to store toothpaste. The outer side of the T-shaped part can be covered with a rubber sleeve, so that when the brush sleeve 14 rotates on the outer side of the T-shaped part through the sleeve groove 112, a small resistance will be generated. The brush sleeve 14 will only rotate when it is manually rotated. This is to prevent the brush sleeve 14 from deflecting when the end of the U-shaped locking rod 26 away from the synchronizing rod 25 is disengaged from the locking hole 27 by pinching the outer sleeve 11. The top of the brush sleeve 14 is also provided with multiple bristles 15.

[0030] Further as Figure 1-6 As shown, it is worth noting that the inner wall of the brush sleeve 14 has a groove 112 that matches the T-shaped part at its center.

[0031] Further as Figure 1-6 As shown, it is worth noting that an ointment tube 13 is fixedly connected to the ointment inlet on the outer side of the tail sleeve 12, and a sealing cap is threaded to the end of the ointment tube 13.

[0032] After the sealing cap is unscrewed, toothpaste can be added from the toothpaste tube 13. The toothpaste can be injected using a manual syringe.

[0033] Further as Figure 1-6As shown, it is worth noting that, in order to facilitate the extrusion of toothpaste from the multiple first toothpaste outlets 141 and to easily adjust the amount of toothpaste dispensed, the toothpaste dispensing adjustment component 2 includes second toothpaste outlets 21 positioned directly below the multiple first toothpaste outlets 141. The multiple second toothpaste outlets 21 are all located on the brush handle 1. On one side of the multiple second toothpaste outlets 21, multiple third toothpaste outlets 22 are also located on the brush handle 1. On one side of the multiple third toothpaste outlets 22, multiple fourth toothpaste outlets 23 are also located on the brush handle 1. The diameter of the second toothpaste outlets 21 is larger than the diameter of the third toothpaste outlets 22. The diameter of hole 22 is larger than that of the fourth ointment outlet hole 23. Multiple spring pieces 24 arranged in a ring array are fixed to the inner wall of the outer sleeve 11. The cross-section of the spring pieces 24 is S-shaped. The same synchronizing rod 25 is fixed to one row of multiple spring pieces 24. A U-shaped locking rod 26 is fixed to the bottom end of the synchronizing rod 25. The U-shaped locking rod 26 is movably inserted into the hollow rod 111. The end of the U-shaped locking rod 26 away from the synchronizing rod 25 extends movably to the outside of the brush handle 1 and is inserted into the locking hole 27 opened in the inner wall of the brush sleeve 14. There are four locking holes 27, which are arranged in a ring array on the inner wall of the brush sleeve 14.

[0034] The diameter of the second toothpaste outlet 21 is larger than that of the third toothpaste outlet 22, and the diameter of the third toothpaste outlet 22 is larger than that of the fourth toothpaste outlet 23. Therefore, when the third toothpaste outlet 22 coincides with the first toothpaste outlet 141, the amount of toothpaste dispensed decreases. When the fourth toothpaste outlet 23 coincides with the first toothpaste outlet 141, the amount of toothpaste dispensed decreases again. The four locking holes 27, with the one closest to the bottom of the brush sleeve 14, are used to seal the toothpaste stored inside. When the end of the U-shaped locking rod 26 away from the synchronizing rod 25 is inserted into this locking hole 27, the multiple first toothpaste outlets 141 on the brush sleeve 14 coincide with the sealed portion on the outside of the brush handle 1. At this point, the toothpaste is no longer squeezed out, facilitating subsequent carrying and preventing toothpaste spillage.

[0035] In summary: When using this novel oral cleaning device, toothpaste is stored in the space between the outer sleeve 11 and the hollow rod 111. When the device is needed to clean teeth, the outer sleeve 11 can be squeezed to deform it. Combined with the multiple spring clips 24, the toothpaste in the aforementioned space is squeezed out through multiple second dispensing holes 21 into multiple first dispensing holes 141, facilitating brushing. If the user needs less toothpaste, squeezing the outer sleeve 11 simultaneously causes the synchronizing rod 25 to move the U-shaped lever 26 downwards, causing the end of the U-shaped lever 26 furthest from the synchronizing rod 25 to exit through the corresponding... The toothpaste sleeve 14 can be rotated because four slots 27 are arranged in a circular array. The toothpaste sleeve 14 rotates outside the handle 1. When multiple first toothpaste outlet holes 141 coincide with multiple third toothpaste outlet holes 22 or multiple fourth toothpaste outlet holes 23, the outer sleeve 11 can be released. Under the rebound force of the spring piece 24, the end of the U-shaped locking rod 26 away from the synchronizing rod 25 is reinserted into the corresponding slot 27, and the toothpaste sleeve 14 is fixed in place. This allows the toothpaste and toothbrush to be used together, reducing the space occupied by carrying them. It also makes it easy to lock the rotated toothpaste sleeve 14, so as to make it convenient to adjust the amount of toothpaste dispensed according to the user's needs.
