The shape and the space size of the accommodating cavity can be set according to the structure and the size of the functional piece 2. The receiving cavity has a receiving opening, which may be located at a surface of any one of the appliance bodies 1. For example, the receiving opening may be formed on the surface of the upper body 11, or the receiving opening may be formed on the surface of the lower body 12, or the receiving opening may be formed on the surface of the tongue portion.

The shift member 5 is connected to the release member 4 for adjusting the release member 4 such that the release member 4 releases the agent at different release rates.

Still further, in this embodiment, the release member 4 includes a cylindrical release cavity 41, a portion of the receiving cavity has a form adapted to the release cavity 41, an area of an inner wall of the portion of the receiving cavity is configured as a groove structure, and an outer wall of the release cavity 41 is attached to and rotates relative to the inner wall of the portion of the receiving cavity.

When the releasing cavity wall area 42 rotates to the inner wall of the partial containing cavity with the groove structure, the groove structure forms a releasing gap with the outer wall of the releasing cavity wall area 42, and the releasing cavity wall area 42 releases the reagent according to the releasing speed of the releasing cavity wall area 42 through the releasing gap. The rest of the releasing cavity wall areas 42 correspondingly rotate to the rest of the inner walls of the part of the accommodating cavities, the outer walls of the rest of the releasing cavity wall areas 42 correspondingly fit with the rest of the inner walls of the part of the accommodating cavities, and the outer walls of the releasing cavity wall areas 42 are sealed by the rest of the inner walls of the part of the accommodating cavities. That is, when it is required to release the reagent at the corresponding release rate, only the release chamber wall section 42 of the release chamber 41 at the corresponding release rate is rotated to a position corresponding to the inner wall of the partial accommodating chamber having the groove structure, so that the release chamber wall section 42 at the release rate releases the reagent at the release gap, and at the same time, the release chamber wall sections 42 of the other remaining release chambers 41 are closed by the remaining inner walls of the accommodating chamber, and the release chamber wall sections 42 of the other remaining release chambers 41 do not release the reagent.

In this embodiment, in order to make the first release chamber 44 release the reagents with different release rates, the first release chamber 44 has first release chamber wall regions 46 with different release rates, and the first release chamber wall regions 46 with different release rates are sequentially arranged along the circumferential cavity of the cylindrical first release chamber 44, and the first release chamber wall regions 46 with different release rates are used for releasing the reagents with different release rates.

In this embodiment, the first release cavity wall regions 46 with different release rates are provided with a plurality of through holes 43 with corresponding aperture sizes, the aperture sizes of the through holes 43 on each first release cavity wall region 46 are different, and the release rates of each first release cavity wall region 46 are different due to the through holes 43 with different aperture sizes. For example, the first release chamber wall sections 46 of the first release chamber 44 at different release rates are set to 3, namely, a first release chamber wall section 46, B first release chamber wall section 46 and C first release chamber wall section 46, a release rate corresponding to the first release chamber wall section 46 is 0.5ml/s (ml characterization unit volume), a release rate corresponding to the first release chamber wall section 46 is 0.1ml/s, and C release rate corresponding to the first release chamber wall section 46 is 1ml/s. Assuming that the numbers of through holes 43 in the a first release chamber wall region 46, the b first release chamber wall region 46 and the C first release chamber wall region 46 are equal (for example, 10 through holes 43), the aperture of the through holes 43 in the a first release chamber wall region 46 is 0.5mm, the aperture of the through holes 43 in the b first release chamber wall region 46 is 0.1mm, and the aperture of the through holes 43 in the C first release chamber wall region 46 is 1mm. Of course, in other examples, the number of through holes 43 in the a first release chamber wall region 46, the b first release chamber wall region 46, and the C first release chamber wall region 46 may be unequal, and the aperture of each through hole 43 in one first release chamber wall region 46 may be unequal, so long as the predetermined release rate is achieved.

After the first release chamber wall sections 46 of the first release chamber 44 are set at different release rates, the reagent needs to be released into the corresponding first release chamber wall sections 46 having the release rate. Specifically, this may be achieved by the second release chamber 45, i.e. the second release chamber 45 has a second release chamber wall area 47, which second release chamber wall area 47, when rotating with the second release chamber 45, can dock with any first release chamber wall area 46 of the first release chamber 44, and after docking, release the reagent contained in the second release chamber 45 sequentially through the second release chamber wall area 47 and the first release chamber wall area 46 docked with the second release chamber wall area 47. That is, when the reagent of the corresponding rate is required to be released, only the second releasing cavity wall area 47 of the second releasing cavity 45 is required to be aligned with the first releasing cavity wall area 46 of the first releasing cavity 44 corresponding to the releasing rate.

The shape and the size of the space of the accommodating chamber can be set according to the structure and the size of the release member 4.

For accurate rotational adjustment of the release chambers, the shift member 5 comprises an adjustment shaft 51, the circumferential end face of the adjustment shaft 51 being provided with different adjustment identification areas 52, each adjustment identification area 52 being opposite to each release chamber wall area. For example, the A adjustment identification zone 52 is identified as 0.5, the B adjustment identification zone 52 is identified as 0.1, the C adjustment identification zone 52 is identified as 1, etc. The adjusting shaft 51 penetrates through the first release cavity 44 and is fixedly connected with the second release cavity 45, and the adjusting shaft 51 drives the second release cavity 45 so that the second release cavity 45 rotates relative to the reagent accommodating cavity 3.

The outer end surface of the adjustment shaft 51 forms a part of the end surface of the appliance body 1.

After the agent is released by the release member 4, it is necessary to deliver the agent to the oral cavity. Specifically, a conveying structure 6 is arranged, the conveying structure 6 is arranged in the appliance main body 1, one end of the conveying structure 6 is communicated with the release gap, and the other end of the conveying structure is communicated with the end face of the appliance main body 1. The function 2 is adjusted to control the release rate of the agent and to deliver agents of different release rates to the oral cavity through the delivery structure 6.

The conveying structure 6 comprises conveying pipes 61, the conveying pipes 61 are distributed in the wall bodies of the upper body 11 and the lower body 12 respectively, a first end of each conveying pipe 61 is communicated with the release gap, and a second end of each conveying pipe 61 is communicated with the end faces of the upper body 11 and the lower body 12 respectively. Wherein, the pipe diameter of the first end to the second end of the conveying pipe 61 is gradually reduced, and the conveying pipe 61 is in a gradually reduced form, so that not only the pressure of releasing the reagent at the second end of the conveying pipe 61 can be increased, but also foreign matters such as oral cavity can be prevented from reversely entering the releasing part 4 through the second end of the conveying pipe 61. The second end of the delivery conduit 61 is provided with an outlet 62, the outlet 62 having a larger diameter than the delivery conduit 61 to facilitate rapid release of the agent into the mouth.

In an embodiment, if the release member 4 comprises a release chamber in the shape of a cylinder, the first end of the delivery conduit 61 communicates with the release chamber wall area of the release chamber. If the release member 4 comprises a first release chamber 44 and a second release chamber 45 in the form of a cylinder, the first end of the delivery conduit 61 communicates with the first release chamber wall region 46 of the first release chamber 44.

In an example, the conveying pipe 61 includes a main conveying pipe 611 and a plurality of branch conveying pipes 612, the main conveying pipe 611 is distributed in the horizontal direction in the wall of each of the upper body 11 and the lower body 12, the plurality of branch conveying pipes 612 are distributed in the vertical direction at intervals in the wall of each of the upper body 11, the lower body 12 and the tongue piece, and one end of each branch conveying pipe 612 is communicated with the main conveying pipe 611, and the other end is communicated with the tooth abutment end face of each of the upper body 11, the lower body 12 and the tongue piece. In this embodiment, the other end of each branch delivery conduit 612 may be positioned opposite each tooth end surface so that the agent may be delivered directly opposite each corresponding tooth. In this embodiment, the pipe diameters of the main conveying pipe 611 and the branch conveying pipe 612 are the same or different, and this embodiment preferably adopts a setting mode in which the pipe diameters of the main conveying pipe 611 and the branch conveying pipe 612 are different, and specifically, the pipe diameter of the main conveying pipe 611 is larger than the pipe diameter of the branch conveying pipe 612, for example, the pipe diameter of the main conveying pipe 611 is set to 1mm, and the pipe diameter of the branch conveying pipe 612 is set to 0.3mm. The manner of this tube diameter arrangement not only facilitates timely and rapid delivery of the agent through the main delivery tube 611, but also facilitates slowing down delivery of the agent to the tooth end surfaces through the smaller tube diameter branch delivery tube 612 as the agent reaches the branch delivery tube 612. The branch delivery conduit 612 is provided with an outlet 62, the outlet 62 being located at the tooth abutment end surfaces of the respective upper body 11, lower body 12 and tongue portion, the outlet 62 having a larger diameter than the diameter of the branch delivery conduit 612 to facilitate rapid release of the agent in the mouth.
