Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.
[0030] In response to the resource waste, increased medical waste, and higher medical care costs associated with the one-piece self-flushing oral care toothbrush design described in the currently published patent "CN216777265U" in practical use, we propose a two-piece self-flushing oral care toothbrush design, the specific solution of which is as follows:
[0031] Example 1:
[0032] like Figures 1-4 As shown, this embodiment provides a split-type self-priming oral care toothbrush, specifically including a handle 1 and a brush head 2. An assembly post 101 is provided at the front end of the handle 1, and the assembly post 101 is integrally formed with the front end of the handle 1. To achieve a detachable assembly between the brush head 2 and the handle 1, and to prevent the brush head from detaching from the front end of the handle 1 during normal use, which could lead to accidental swallowing of the brush head by patients with sudden illnesses and resulting in medical safety accidents, an L-shaped rotating locking groove 102 is provided on the outer side of the assembly post 101. A rotating latch 201 is integrally formed on the inner side of the tail end of the brush head 2 to engage with the rotating locking groove 102. The tail end of the brush head 2 is fitted onto the assembly post 101, and by rotating the brush head 2, the rotating latch 201 engages with the rotating locking groove 102, thus achieving a split-type assembly.
[0033] To enable the toothbrush to rinse and flush autonomously in conjunction with oral care devices, and to facilitate better control of the rinsing and flushing operation by the user, a main water delivery channel 103 and a main suction channel 104 are provided inside the handle 1. The brush head 2 has auxiliary water delivery channels 202 and auxiliary suction channels 203 that connect with the main water delivery channels 103 and 104. A water outlet hole communicating with the auxiliary water delivery channel 202 is located at the bristle gaps at the front end of the brush head 2, while a water outlet hole communicating with the auxiliary suction channel 203 is located at the outer edge of the front end of the brush head 2. The channel 203 connects to the suction port. A rotary switch 3 is installed in the main water supply channel 103. The operator can control the opening and closing of the main water supply channel 103 by turning the rotary switch 3 on the outside of the handle 1. In order to facilitate the operator to adjust the suction speed of the liquid inside the mouth, a suction control hole 4 connected to the main suction channel 104 is provided in the middle of the handle 1. The operator can block the suction control hole 4 with the fingertip to adjust the negative pressure suction intensity at the suction port at the front end of the brush head 2, thereby achieving the purpose of adjusting the suction effect.
[0034] To facilitate connection between the toothbrush and oral care rinsing equipment, a docking part 5 is installed at the tail end of the handle 1. The docking part 5 is provided with a quick-connect interface that connects to the main water delivery channel 103 and the main suction channel 104, so as to connect to the oral care rinsing equipment through a hose. In order to prevent water leakage, a rear rubber pad 6 and a front rubber pad 7 are respectively provided between the handle 1, the docking part 5 and the brush head 2. The rear rubber pad 6 and the front rubber pad 7 are provided with through holes corresponding to the positions of the main water delivery channel 103 and the main suction channel 104.
[0035] To further improve the safety of detachable self-priming toothbrushes during use and reduce the risk of brush heads falling off, we propose an alternative implementation plan, as follows:
[0036] Example 2:
[0037] like Figures 5-7 As shown, this embodiment differs from Embodiment 1 in that: the handle 1 consists of two parts: a water control module 106 and a suction module 105. The brush head 2 and the front end of the suction module 105 are integrally formed, eliminating the assembly post 101, the rotating locking groove 102, and the rotating locking buckle 201. Simultaneously, the docking part 5 is assembled with the tail end of the suction module 105. An assembly groove 151 is provided in the middle of the suction module 105, and the water control module 106 is detachably assembled into the assembly groove 151 on the suction module 105. The specific design is as follows:
[0038] Its main suction channel 104 is located inside the suction module 105. The first rear wedge groove 154 and the side lug 152 are integrally formed at the tail end and both sides of the assembly groove 151 of the suction module 105, respectively. At the same time, a rear docking hole 153 is integrally formed at the middle of the tail end of the assembly groove 151. A front docking hole 155 is provided at the front end of the assembly groove 151 corresponding to the auxiliary water supply channel 202. Adaptor grooves 161 that cooperate with the side lug 152 are provided on both sides of the water control module 106.
[0039] To complete the separate assembly of the water control module 106 and the suction module 105, the main water delivery channel 103 is located inside the water control module 106. At the tail end of the water control module 106, corresponding to the position of the first rear wedge groove 154 and the rear docking hole 153, a second rear wedge platform 162 and a rear connector 163 are integrally formed to mate with the first rear wedge groove 154 and the rear docking hole 153. In order to prevent water leakage from the insertion between the rear connector 163 and the rear docking hole 153, a sealing ring is provided on the outer side of the rear connector 163.
[0040] Meanwhile, an assembly hole 164 is provided at the front end of the water control module 106 corresponding to the main water supply channel 103, and the front end of the assembly hole 164 is sealed by an annular plug 165. A connecting pipe 166 is slidably inserted into the front end of the main water supply channel 103. The front end of the connecting pipe 166 slides through the plug 165 and extends to the outside of the water control module 106. A retaining ring 167 is integrally formed on the outer wall of the connecting pipe 166 inside the assembly hole 164. A spring 168 is provided on the side of the retaining ring 167 away from the plug 165, which is fitted onto the connecting pipe 166. The spring 168 applies an outward pushing force to the connecting pipe 166 through the retaining ring 167. In order to facilitate the water control module 106... During the assembly process of 6, the front end of the connecting pipe 166 can automatically engage with or disengage from the front docking hole 155. The outer surface of the water outlet at the front end of the connecting pipe 166 adopts a smooth arc-shaped spherical design, while the inner side of the front docking hole 155 adopts an arc-shaped groove design that matches the structure of the front end of the connecting pipe 166. Furthermore, in order to prevent water leakage between the connecting pipe 166 and the front docking hole 155 and the main water supply channel 103, a rubber ring is fixed on the outer side of the water outlet at the front end of the connecting pipe 166, and a Y-shaped sealing ring is provided between the outer side of the tail end of the connecting pipe 166 and the main water supply channel 103.
[0041] Example 3:
[0042] like Figures 8-9As shown, this embodiment differs from Embodiment 2 in that: the docking part 5 is assembled with the tail end of the water control module 106; the design of the front docking pipe 166, assembly hole 164, plug 165, retaining ring 167, and spring 168 of the water control module 106 in Embodiment 2 is omitted; instead, a front docking connector 169 is integrally formed at the front end of the water control module 106 corresponding to the position of the main water delivery channel 103, which is inserted and mates with the front docking hole 155; and the design of the second rear wedge 162 and rear docking connector 163 at the tail end of the water control module 106 in Embodiment 2 is omitted; instead, a second rear wedge groove 1610 is integrally formed on the inner side of the tail end of the water control module 106, and simultaneously at the tail end of the suction module 105... The end is integrally formed with a first rear wedge platform 156 that engages with the second wedge groove. At the same time, the side ears 152 on the suction module 105 and the side opposite to the adapter groove 161 on the water control module 106 are slidably engaged. The suction module 105 is slidably engaged with the water control module 106 from the front end to the rear through the engagement of the side ears 152 and the adapter groove 161, so that the suction module 105 and the water control module 106 form a main negative pressure suction channel. In order to prevent water leakage in the main suction channel 104 formed by the combination, a rubber pad can be set at the joint position between the suction module 105 and the water control module 106 to improve the sealing of the joint or snap-fit gap.
[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
