Therefore, they should not be construed as limitations on this application.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0027] Please refer to the following: Figures 1 to 5The cleaning brush head 10 shown in this embodiment of the present invention is used in conjunction with the cleaning device body 20 of the oral cleaning device 1. The cleaning device body 20 can supply a cleaning medium to the cleaning brush head 10, which can be a liquid or a gas.

[0028] The cleaning brush head 10 provided in this application embodiment will now be described. The cleaning brush head 10 includes a bristle plate 11 and a brush head body 12. The bristle plate 11 includes a brush plate 111 and bristles 112, with the bristles 112 disposed on the brush plate 111. The brush plate 111 has cleaning holes 113 along its thickness direction. The brush plate 111 is detachably connected to the brush head body 12. The brush head body 12 has a flow channel 121, and the outlet 1211 of the flow channel is connected to the inlet of the cleaning hole 113.

[0029] Compared with the prior art, the cleaning brush head 10 provided in this application embodiment has a detachable connection between the brush head body 12 and the bristle plate 11, which facilitates the disassembly, cleaning, and replacement of both the brush head body 12 and the bristle plate 11. When the brush plate 111 and / or the bristles 112 of the bristle plate 11 are damaged, it is only necessary to remove the bristle plate 11 from the brush head body 12 for replacement, and the brush head body 12 can continue to be used, reducing material waste. Moreover, by providing cleaning holes 113 on the bristle plate 11 and providing flow channels 121 on the brush head body 12 that communicate with the cleaning holes 113, the cleaning medium can be directionally delivered. The cleaning medium is injected through the flow channels 121 and then sprayed onto the surface of the bristles 112 through the cleaning holes 113, achieving deep cleaning of the bristles 112 and effectively improving cleaning efficiency.

[0030] Understandably, the brush plate 111 includes a top surface and a bottom surface. The top surface is the side facing the teeth when in use, and the bottom surface is the side facing away from the teeth. The bristles 112 can be set on at least the top surface of the brush plate 111. In some designs, some of the bristles 112 can also be set on the side between the top and bottom surfaces for multi-angle oral cleaning.

[0031] Optionally, the outlets of the bristles 112 and the cleaning holes 113 are located on the same side of the brush plate 111, and the cleaning medium is sprayed directly onto the bristles 112 from the outlet of the cleaning holes 113, thereby increasing the cleaning power of the bristles 112.

[0032] Optionally, the brush plate 111 is provided with a first connecting structure 1111, and the brush head body 12 includes a base 122. The outlet of the flow channel 121 is disposed on the base 122. The base 122 is provided with a second connecting structure 124. One of the first connecting structure 1111 and the second connecting structure 124 is a connecting block, and the other is a connecting groove. The first connecting structure 1111 is slidably connected to the second connecting structure 124 along a first direction. This arrangement facilitates the assembly of the brush plate 11 and the brush head body 12.

[0033] The first connecting structure 1111 and the second connecting structure 124 can be understood as a sliding rail connecting system, with the connecting groove being a guide rail groove and the connecting block acting as a slider to form a sliding fit with the connecting groove. When the connecting block slides into the connecting groove, the friction between the two not only achieves the mechanical connection between the brush plate 111 and the brush head body 12, but also provides a controllable displacement path for the bristle plate 11 through the sliding fit between the connecting groove and the connecting block. This arrangement ensures both the connection between the bristle plate 11 and the brush head body 12 and the precise positioning of the bristle plate 11 on the brush head body 12.

[0034] In some embodiments, the first connecting structure 1111 is a connecting block, and the second connecting structure 124 is a connecting groove. The connecting groove extends through one end of the base 122 along the first direction X to form an insertion inlet / outlet 1241, which allows the connecting block to enter and exit the connecting groove. When installing the brush plate 11 on the brush head body 12, the brush plate 111 of the brush plate 11 is first aligned with the insertion inlet / outlet 1241 of the connecting groove and inserted into the connecting groove, so that the connecting block and the connecting groove form an initial fit. Then, the brush plate 11 is pushed to slide in the connecting groove until the entire brush plate 11 moves to the predetermined position. At this time, the outlet of the flow channel 121 is also aligned with the inlet of the cleaning hole 113, so that the cleaning medium in the flow channel 121 can flow smoothly into the cleaning hole 113.

[0035] To ensure the aesthetics of the entire cleaning brush head 10, the brush plate 111 further includes a limiting block 1112 connected to the first connecting structure 1111. The size of the limiting block 1112 is larger than that of the connecting block, and a plate limiting step surface 1113 is formed between the limiting block 1112 and the first connecting structure 1111. The base 122 includes a base plate 1221 and a surrounding plate 1222 disposed on the base plate 1221. The surrounding plate 1222 is located on the side of the base plate 1221 near the brush plate 111 and forms a connecting groove. The end of the surrounding plate 1222 near the insertion inlet / outlet 1241 abuts against the plate limiting step surface 1113. The outer peripheral surface of the limiting block 1112 is flush with the outer peripheral surface of the surrounding plate 1222 and also flush with the outer peripheral surface of the base plate 1221.

[0036] In some embodiments, the brush plate 111 is provided with a first limiting structure 115, and the base 122 is provided with a second limiting structure 126. One of the first limiting structure 115 and the second limiting structure 126 is a limiting protrusion, and the other is a limiting groove. The first limiting structure 115 and the second limiting structure 126 are fastened together.

[0037] Understandably, when the first limiting structure 115 is a limiting protrusion, the second limiting structure 126 is a limiting groove; when the first limiting structure 115 is a limiting groove, the second limiting structure 126 is a limiting protrusion. The limiting protrusion and the limiting groove match each other to form a snap-fit ​​connection.

[0038] After the first connecting structure 1111 and the second connecting structure 124 complete the sliding connection, the first limiting structure 115 and the second limiting structure 126 simultaneously complete the snap-fit ​​connection, assisting the first connecting structure 1111 and the second connecting structure 124 in connecting the bristle plate 11 and the brush head body 12, strengthening the connection force between the bristle plate 11 and the brush head body 12, making it less likely for the brush plate 111 to detach from the base 122. Moreover, due to the stroke limitation of the first connecting structure 1111 on the second connecting structure 124, the first limiting structure 115 can also move precisely to the position of the second limiting structure 126, realizing the snap-fit ​​with the second limiting structure 126.

[0039] In some embodiments, the first limiting structure 115 is a limiting protrusion, and the second limiting structure 126 is a limiting groove. The two opposite sides of the limiting protrusion along the second direction Y are arc surfaces, and the two opposite groove walls of the limiting groove along the second direction Y are arc surfaces. The second direction Y is perpendicular to the first direction X. This arrangement can reduce the resistance and edge wear when the limiting protrusion and the limiting groove are engaged, and also facilitates the entry and exit of the limiting protrusion from the limiting groove.

[0040] When the connecting groove is located on the base 122, the first limiting structure 115 can be located on the bottom or side of the brush plate 111, and the second limiting structure 126 can be located on the bottom or side wall of the connecting groove. For example, Figure 2 and Figure 3 As shown, the first limiting structure 115 is located on the bottom surface of the brush plate 111, and the second limiting structure 126 is located on the bottom of the connecting groove.

[0041] Please see Figure 1 and Figure 2 In some embodiments, the brush head body 12 further includes a rod 127, one end of which is connected to the base 122, and the other end is used to connect to the cleaning device body 20 of the oral cleaning device, forming a bridge connecting the entire cleaning brush head 10 and the cleaning device body 20.

[0042] Optionally, the rod 127 and the insertion inlet / outlet 1241 are located at opposite ends of the base 122 along its length. The outlet of the flow channel 121 is located on the base 122, and the flow channel 121 extends from the base 122 through the rod 127. The inlet of the flow channel 121 is located on the rod 127 to ensure that the cleaning medium can be stably delivered to the brush plate 111 through the flow channel 121. The rod 127 not only achieves mechanical connection but also supports the efficient flow of the medium through its internal flow channel 121, serving as a functional bridge between the cleaning brush head 10 and the main body 20 of the cleaning device, ensuring the continuous operation of the oral cleaning device.

[0043] like Figure 5As shown, in some embodiments, the flow channel 121 includes a first segment 1212, a second segment 1213, and a third segment 1214 connected in sequence. The first segment 1212 is formed on the base 122, and the second segment 1213 and the third segment 1214 are both formed on the rod portion 127. The inner diameter of the flow channel 121 increases segment by segment from the first segment 1212 to the third segment 1214, that is, the inner diameter of the first segment 1212 < the inner diameter of the second segment 1213 < the inner diameter of the third segment 1214. Clean gas or liquid is input from the third section 1214 and flows into the first section 1212. The gas or liquid in the third section 1214 pushes the gas or liquid in the second section 1213, which in turn pushes the gas or liquid in the first section 1212. Since the inner diameter of the flow channel 121 gradually decreases from the third section 1214 to the first section 1212, the pressure will gradually increase, thereby increasing the pressure of the gas or liquid ejected from the outlet of the first section 1212 and increasing the cleaning power.

[0044] In some embodiments, the third segment 1214 can also serve as a groove for connecting the rod 127 to the handle 21, so that one end of the medium supply handle 21 can be inserted into the third segment 1214 for a secure connection.

[0045] In some embodiments, the base 122 is provided with a support column 128, a section of the flow channel 121 is disposed in the support column 128, the outlet of the flow channel 121 is disposed on the support column 128, the brush plate 111 has a groove 116 that matches the support column 128, the support column 128 is inserted into the groove 116, and the cleaning hole 113 communicates with the groove 116. After the first connecting structure 1111 and the second connecting structure 124 are connected, the support column 128 slides into the groove 116, forming a double limit.

[0046] Furthermore, both the support column 128 and the column groove 116 extend along the length of the rod portion 127, that is, the extension direction of the support column 128 is parallel to the sliding connection direction of the first connecting structure 1111 and the second connecting structure 124, which facilitates the simultaneous sliding of the support column 128 into the column groove 116 and the brush plate 111 into the connecting groove.

[0047] Understandably, the dimension of the end of the support column 128 near the insertion port 1241 gradually decreases in the direction away from the insertion port 1241. This arrangement enables the end of the support column 128 near the insertion port 1241 to have a guiding effect, so that the support column 128 can be smoothly inserted into the column groove 116.

[0048] To reduce wear caused by sharp edges, preferably, the two opposite sides of the support column 128 along the second direction Y are arc surfaces, and the two opposite groove walls of the column groove 116 along the second direction are arc surfaces. This arrangement can also increase the contact area between the brush plate 111 and the base 122, increase the friction between the brush plate 111 and the base 122, and further strengthen the connection between the brush plate 11 and the base 122.

[0049] In some embodiments, a drain hole 129 is provided through the base 122 along its thickness direction. The drain hole 129 is located near the bottom of the column groove 116. One end of the drain hole 129 is connected to the column groove 116, and the other end is connected to the outside. The drain hole 129 is specifically provided on the base plate 1221. When the brush plate 11 is cleaned with a liquid cleaning medium, some of the liquid cleaning medium may seep into the gap between the base 122 and the brush plate 111. The design of the drain hole 129 facilitates the drainage of the liquid cleaning medium in the gap, reduces the retention of liquid cleaning medium in the gap, and facilitates the rapid drying of the base plate 1221.

[0050] In some embodiments, the support column 128 has a media ejection end 1281, the outlet of the flow channel 121 is located on the media ejection end 1281, and the media ejection end 1281 partially extends into the drain hole 129. Specifically, the media ejection end 1281 is disposed near the insertion inlet / outlet 1241, the outlet of the flow channel 121 is located on the media ejection end 1281, and the media ejection end 1281 is aligned with the drain hole 129. This arrangement makes the drain hole 129 very close to the outlet of the flow channel 121, thereby allowing the cleaning medium to flow into the drain hole 129 with a shorter path and then be discharged through the drain hole 129.

[0051] The media ejection end 1281 extends into the drain hole. This arrangement helps to further shorten the distance that the cleaning media needs to flow into the drain hole 129, thereby further facilitating the rapid discharge of the cleaning media between the brush plate 111 and the base 122.

[0052] Please see Figures 6 to 8 This application also provides an oral cleaning device 1, including the aforementioned cleaning brush head 10 and a cleaning device body 20. The cleaning device body 20 includes a handle 21 connected to the brush head body 12. A fluid generator 25 is disposed within the handle 21 and connected to the inlet of a flow channel 121. The fluid generator 25 provides power to the cleaning medium, driving the cleaning medium through the flow channel 121 to the cleaning hole. The fluid generator 25 can be a drive pump such as an air pump.

[0053] Understandably, the fluid generator 25 can be directly connected to the inlet of the flow channel 121, or it can be connected to the inlet of the flow channel 121 through a pipe.

[0054] The handle 21 and the brush head body 12 can be either fixedly connected or detachably connected. When the handle 21 and the brush head body 12 are detachably connected, it is possible to replace the bristles 112 by only replacing the bristle plate 11 or cleaning the brush head 10, thereby recycling the cleaning device body 20 and effectively improving material utilization.

[0055] In some embodiments, the handle 21 is detachably connected to the brush head body 12. The handle 21 has a flow inlet channel 211, which is connected to the flow channel 121. The end of the flow inlet channel 211 away from the brush head body 12 has an inlet. Gas or liquid enters from the inlet of the flow inlet channel 211, is delivered to the flow channel 121, and is then sprayed out from the cleaning hole 113 to clean the bristles 112 and the brush plate 111.

[0056] The oral cleaning device 1 provided in this application embodiment has a handle 21 for gripping. In use, the cleaning brush head 10 is connected to the main body 20 of the cleaning device to form a complete oral cleaning device 1. The bristle plate 11 is detachably connected to the brush head body 12, facilitating cleaning and replacement of the bristle plate 11. Furthermore, if only the brush plate 111 and / or bristles 112 are damaged, and neither the main body 20 nor the brush head body 12 is damaged, only the bristle plate 11 can be replaced, significantly reducing waste and extending the service life of the main body 20 and the brush head body 12. Of course, users can also replace the entire cleaning brush head 10, offering flexibility, convenience, and diverse applications.

[0057] In some embodiments, the handle 21 includes a transition section 212 for connecting to the brush head body 12. The connection between the transition section 212 and the brush head body 12 is provided with a sealing structure 22 to reduce leakage of the cleaning medium and allow the cleaning medium to be smoothly discharged from the flow channel 121 and the receiving channel 211.

[0058] Specifically, the transition section 212 is connected to the rod 127 in the brush head body 12, and the third section 1214 of the transition section 212 is inserted into the flow channel 121 and connected to the rod 127. The connection method can be screw connection, snap-fit ​​connection or other convenient detachable connection.

[0059] In some embodiments, the main body 20 of the cleaning device further includes a display screen 23, a power supply component 24, and a power switch. The display screen 23, the power supply component 24, and the power switch are all mounted on the handle 21. The display screen 23 is electrically connected to the power supply component 24, and the power switch is also electrically connected to the power supply component 24. The power switch is used to control the power supply to or off of the display screen 23 and the power supply component 24. The display screen 23 may be designed to display information including, but not limited to, temperature, humidity, and time. The fluid generator 25 is connected to the flow channel 211 and is used to generate a driving force that drives the cleaning medium to flow into the flow channel 121. The power supply component 24 is used to provide electrical energy to the display screen 23, the power switch, and the fluid generator 25 so that the display screen 23, the power switch, and the fluid generator 25 can operate. The power supply component 24 may be a non-rechargeable battery or a rechargeable battery.

[0060] In some embodiments, the cleaning device body 20 further includes a charging structure 26, which is electrically connected to the power component 24 and is used to charge the power component 24.
