Technical Field

[0002] The present application relates to the field of oral cleaning technology, and in particular to a brush head care container. Background Art

[0003] After using a toothbrush, the bristles become damp, making it easy for bacteria to grow. A toothbrush laden with bacteria can easily cause oral and intestinal problems when used again. To address this issue, a toothbrush case has emerged on the market for drying and storing toothbrushes. After use, the toothbrush can be placed in the case to dry, improving the user experience.

DETAILED DESCRIPTION

[0045] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0046] With reference to Figures 1 to 8, the present application provides a brush head care container, comprising: a main body 1 formed by a middle shell 401, a side wall 201 and a bottom shell 901, a middle cavity 400 is formed inside, a fan assembly 100 is provided at one end of the middle cavity 400 on a first radial direction 21 of the first axis 2, a drainage outlet 405 is provided at a position corresponding to the shell of the middle shell 401 at one end of the middle cavity 400 and the fan assembly 100, a fluid inlet 204 is provided on the side wall 201, and a fluid inlet 204 is provided on a second radial direction 21 of the first axis 2. A limiting member 407 with an opening 403 is formed at the second end of the main body 1 upward 22, and the first radial direction 21 and the second radial direction 22 are set at an angle; the top cover 10 is movably connected to the main body 1, and is surrounded by the main body 1 to form a receiving cavity 404 that can accommodate part of the brush head assembly; the limiting member 407 is used to allow at least part of the brush head assembly to enter the receiving cavity and remain in a position corresponding to the drainage outlet 405, and the fan assembly 100 is configured to draw air from the fluid inlet 204 and discharge air from the drainage outlet 405 to the receiving cavity.

[0047] In one embodiment, the side wall 201 is a rotational curved surface, the rotation axis of the rotational curved surface coincides with the first axis 2 , the projection of the main body 1 on the section perpendicular to the first axis 2 is circular or nearly circular, and the central axis of the main body 1 coincides with the first axis 2 .

[0048] The brush head care container separates the accommodating cavity 404 for accommodating the brush head assembly from the middle cavity 400 for installing other components through the middle shell 401, and forms a drainage outlet 405 on the side with the largest area of ​​the corresponding brush head side, so that the flowing air formed by the fan assembly 100 can be blown from the drainage outlet 405 to the side of the bristles, that is, the surface with the largest area of ​​the bristles, so that the thickness of the bristles that the air flow needs to flow through is thinner. While forming a large area of ​​blowing and drying the bristles, the difficulty of air blowing through the bristles is reduced, so that the air can fully dry the bristles, the drying efficiency is higher, and the wet time of the bristles can be greatly shortened, effectively preventing bacteria from breeding on the toothbrush bristles, and improving the user experience.

[0049] Since the middle cavity 400 where other components are installed is separated from the accommodating cavity 404 by the middle shell 401, when the bristles are dried by airflow, the airflow will not enter the middle cavity 400 from the accommodating cavity 404 when entering the accommodating cavity 404. Therefore, it is possible to prevent the moist gas carried away by the airflow during the process of drying the bristles from entering the middle cavity 400 and causing corrosion to other components.

[0050] A plane perpendicular to the first axis 2 is set as a projection plane, and the projections of the middle shell 401 and the bottom shell 901 on the projection plane are circular or approximately circular, with the center of the projection located on the first axis 2 .

[0051] The top cover 10 includes a separate upper shell 102 and a skylight 101. The upper shell 102 is rotatably connected to the side wall 201. When the top cover 10 is closed on the side wall 201, the projection of the top cover 10 on the plane perpendicular to the first axis 2 is set as the projection plane. The projection of the top cover 10 on the projection plane is circular or approximately circular. The top cover 10 includes the annular upper shell 102 and the circular skylight 101. The centers of the projections of the upper shell 102 and skylight 101 are located on the first axis 2. The skylight 101 is located in the center area of ​​the upper shell 102 and forms a closed structure with the inner ring of the upper shell 102. The skylight 101 can be transparent or translucent and can be used as an observation window to observe the structure within the main body 1.

[0052] The fluid inlet 204 is located on the third radial direction 23 of the first axis 2 . The third radial direction 23 may form an angle of 90° with the second radial direction 22 . The angle between the second radial direction 22 and the first radial direction 21 is less than 90°.

[0053] In this embodiment, the fluid inlet 204 and the fluid channel 114 are staggered along the circumference of the side wall 201, so that the fan 110 and other structures in the fluid channel 114 cannot be directly seen from the fluid inlet 204, which can improve the overall appearance of the brush head care container and avoid exposing internal devices.

[0054] In one embodiment, a fluid outlet 402 is further formed at the second end of the main body 1 on the second radial direction 22 of the first axis 2, and the fluid outlet 402 and the opening 403 of the limit member 407 are spaced apart along the extension direction of the first axis 2; the fan assembly 100 is also configured to discharge the air in the accommodating cavity from the fluid outlet 402.

[0055] When the air flow enters the accommodating chamber 404 from the fluid inlet under the action of the fan assembly 100 to dry the brush head assembly, it takes away the moisture on the brush head assembly and then flows out from the fluid outlet 402. Under the circulation of dry air, the bristles of the brush head assembly are quickly dried, making it difficult to form an environment suitable for bacteria, thereby effectively inhibiting the growth of bacteria.

[0056] In one embodiment, the brush head care container is a wall-mounted structure. When the brush head care container is wall-mounted, the fluid outlet 402 is located at the lower side of the accommodating cavity 404 , and the drainage outlet 405 is located on the side of the accommodating cavity 404 adjacent to the fluid outlet 402 .

[0057] In this embodiment, when the brush head care container is hung on the wall, the accommodating cavity 404 is located at the lower side of the brush head care container, and the fluid outlet 402 is located at the lower side of the accommodating cavity 404. Therefore, when the brush head care container is hung on the wall, the fluid outlet 402 is located at the bottom of the brush head care container. In this case, after the toothbrush is placed in the accommodating cavity 404, it is in a hanging state, and the brush head 601 of the toothbrush is located in the accommodating cavity 404, and the neck of the brush head 601 is hung on the side wall of the accommodating cavity 404, so that the brush head 601 can be kept in the accommodating cavity 404, which is convenient for the installation and positioning of the toothbrush in the brush head care container. After the toothbrush is placed in the brush head care container, water droplets will drip from the bristles under the action of gravity and fall into the lowest position of the accommodating chamber 404. Since the fluid outlet 402 is located at the lowest position of the accommodating chamber 404, the dripping water droplets can flow out of the fluid outlet 402 under the action of gravity, accelerating the loss of water from the bristles. At this time, the fluid outlet 402 not only has the function of discharging air, but also has the function of draining water. Due to the location and direction of the fluid outlet 402, the direction of the airflow is consistent with the direction of the water droplets under the action of gravity. Therefore, the flow of air can further accelerate the flow of water droplets, allowing the water on the bristles to be separated from the bristles more quickly under the action of the airflow, which can further improve the water removal efficiency of the bristles, improve the drying efficiency and effect of the bristles, and prevent the growth of microorganisms in a humid environment.

[0058] To ensure smooth airflow, a relief opening 203 is provided on the housing at a position corresponding to the fluid outlet 402. The area of ​​the relief opening 203 is larger than or equal to the fluid outlet 402, and its shape matches the fluid outlet 402, ensuring that airflow and water droplets can be smoothly discharged from the fluid outlet 402. To prevent dust and other particles from entering the accommodating chamber 404 through the relief opening 203 and the fluid outlet 402 when the brush head care container is not in use, a dust plug 202 is provided at the relief opening 203. The dust plug 202 is made of an elastic material and effectively blocks the relief opening 203. The dust plug 202 can be made of rubber, for example.

[0059] A cover plate 902 is further provided on the outside of the bottom shell 901, wherein the cover plate 902 covers the bottom shell 901, pressing the bottom shell 901 against the side wall 201. The cover plate 902 and the bottom shell 901 can be fixed by hooks. The cover plate 902 and the side wall 201 can be fixed by hooks or bolts.

[0060] In one embodiment, the fan assembly 100 includes a fan 110, the fan 110 includes one or more fan blades 111, and the drainage outlet 405 includes one or more drainage sub-windows. The drainage outlet 405 introduces the fluid from the outside of the main body 1 through the fan assembly 100 into the accommodating cavity 404 through the drainage sub-window to dry the brush head assembly in the accommodating cavity 404.

[0061] In one embodiment, the drainage outlet 405 includes drainage sub-windows having the same number as the fan blades 111 and matching shapes and contours.

[0062] In one embodiment, the number of the drainage sub-windows is less than the number of the fan blades 111 , which can further reduce the blocking area of ​​the drainage sub-windows and reduce the flow resistance of the airflow drawn out by the fan blades 111 .

[0063] In one embodiment, the fan assembly 100 further includes a fluid channel 114 extending along the second axis 3 , and the second axis 3 passes through a center point of the drainage outlet 405 .

[0064] In this embodiment, the fluid channel 114 extends along the second axis 3, and the second axis 3 is the center line of the fluid channel 114. The second axis 3 passes through the center point of the drainage outlet 405, so that the center line of the fluid channel 114 also passes through the center point of the drainage outlet 405. The central axis of the fan assembly 100 can be basically aligned with the center of the drainage outlet 405, and the air outlet of the fan assembly 100 can face the maximum area of ​​the bristle side of the brush head assembly, thereby enhancing the drying efficiency and drying effect of the bristles.

[0065] In one embodiment, the rotation axis 119 of the fan assembly 100 is arranged along the extension direction of the second axis 3 , and the distance between the drainage outlet 405 and the top surface of the rotation axis 119 of the fan 110 is 3 mm to 5 mm.

[0066] In this embodiment, the rotating shaft 119 of the fan 110, the central axis of the fluid channel 114 and the second axis 3 basically coincide with each other, so that the installation structure of the fan 110 and the fluid channel 114 is more optimized, which can reduce the air supply resistance, increase the air supply flow rate, and improve the drying efficiency.

[0067] The distance between the drainage outlet 405 and the top surface of the rotating shaft of the fan 110 is 3mm to 5mm, that is, the distance between the inner wall surface of the drainage outlet 405 close to the fan 110 and the end of the fan blade 111 of the fan 110 close to the drainage outlet 405 on the second axis 3 is 3mm to 5mm. This can avoid the distance between the inner wall surface of the drainage outlet 405 and the fan blade 111 of the fan 110 being too small, resulting in interference between the fan blade 111 and the inner wall surface. It can also avoid the distance between the inner wall surface of the drainage outlet 405 and the fan blade 111 of the fan 110 being too large, resulting in excessive flow loss in the process of the fluid flowing from the fan blade 111 to the drainage outlet 405, so that the fluid can obtain better flow performance and flow efficiency in the process of flowing from the fan blade 111 to the drainage outlet 405, and has higher safety and reliability.

[0068] In one embodiment, the length of the fluid channel 114 of the fan assembly 100 along the extension direction of the second axis 3 is 20 mm to 27 mm. In this embodiment, limiting the length of the fluid channel 114 of the fan assembly 100 along the second axis 3 to 20 mm to 27 mm ensures sufficient space for the installation of the fan 110 and the fan blades, while preventing the fluid channel 114 from being too long, which would increase the overall volume of the brush head care container. This ensures a more compact structure while ensuring air supply capacity.

[0069] In one embodiment, the distance between the edge of the fan blade 111 of the fan 110 and the wall of the fluid channel is 0.5 mm to 1 mm. In this embodiment, the distance between the edge of the fan blade 111 of the fan 110 and the wall of the fluid channel needs to be greater than or equal to 0.5 mm to avoid interference between the fan blade 111 and the wall of the fluid channel 114 during rotation due to a too small distance, thereby damaging the fan blade 111. At the same time, the distance needs to be less than or equal to 1 mm to avoid leakage of fluid from the gap due to an excessive distance, thereby reducing the flow efficiency of the fluid.

[0070] In one embodiment, the second axis 3 intersects the second radial direction 22 of the first axis 2 at right angles, so that after the fluid enters the accommodating chamber 404 from the fluid channel 114, it is easier to turn and then flow out from the fluid outlet 402 and the opening 403 extending along the second radial direction 22, thereby reducing flow loss during the turning process.

[0071] In one embodiment, the fan assembly 100 further includes a motor bracket 113 . The motor bracket 113 is disposed on the air duct wall 406 of the fluid channel 114 , and the fan 110 is mounted on the motor bracket 113 .

[0072] In this embodiment, the fan 110 includes a fan blade 111 and a motor 112. The motor bracket 113 is mounted on the air duct wall 406. The motor 112 is mounted on the motor bracket 113. The fan blade 111 is mounted on the output shaft of the motor 112. The fan blade 111 is arranged at one end of the motor 112 near the drainage outlet 405 and is arranged corresponding to the drainage outlet 405. It can effectively transport the airflow into the accommodating chamber 404 to dry the bristles. The ventilation area of ​​the drainage outlet 405 is greater than or equal to the circular area defined by the diameter of the fan blade 111, so that the airflow of the fan blade 111 will not be blocked by the drainage outlet 405 and can more fully enter the accommodating chamber 404, thereby improving the air intake efficiency.

[0073] In one embodiment, the motor bracket 113 is provided with an avoidance structure for fluid to flow through. The avoidance structure penetrates the motor bracket 113 along the extension direction of the second axis 3 , and the fluid flows from the fluid inlet 204 to the fluid outlet 402 through the avoidance structure.

[0074] In one embodiment, the motor bracket 113 includes a cylindrical structure and a plurality of connecting arms arranged in the cylindrical structure. The central axis of the cylindrical structure coincides with the second axis 3. The connecting arms are radially distributed around the second axis 3 on the inner wall of the cylindrical structure. The fan 110 is located in the central area of ​​the radial structure formed by the connecting arms and is connected and fixed by the connecting arms.

[0075] Adjacent connecting arms can form a flow channel, which can reduce the flow resistance of motor bracket 113 to the airflow and improve the flow efficiency of the airflow. In one embodiment, one end of the connecting arm can be directly fixed to the air duct wall 406, and the other end can be fixedly connected to the motor 112. The motor bracket 113 can be detachably connected to the air duct wall 406 by means of bolts or other means.

[0076] The motor bracket 113 adopts a cylindrical structure to install the fan 110, and the fan blades of the fan 110 are evenly distributed along the circumference. The annular structure formed by the cylindrical structure and the circumferential balance structure formed by the circumferential uniform distribution of the fan blades 111 can be utilized to ensure that the circumferential mass distribution of the motor bracket 113 and the fan blades 111 is uniform, so that the fan assembly 100 has good dynamic balance performance.

[0077] In one embodiment, fan assembly 100 includes a fan 110 and a motor bracket 113. Fan assembly 100 also includes a fluid channel 114 extending along second axis 3. Motor bracket 113 is disposed on the duct wall of fluid channel 114. The central axis of fan 110 is parallel to or coincides with second axis 3. Fan 110 is provided with a vibration damping sleeve 116 on its outer shell. Fan 110 is mounted within motor bracket 113 via vibration damping sleeve 116, and fan 110 and motor bracket 113 do not contact each other. Motor bracket 113 is mounted to the main structure via screws 117.

[0078] In this embodiment, by disposing a vibration-damping sleeve 116 outside the motor 112 of the fan 110, the vibration-damping sleeve 116 can be used to form a vibration-damping fit between the motor 112 and the motor bracket 113, thereby reducing the transmission of vibration effects during the operation of the motor 112 to the motor bracket 113, thereby effectively reducing the noise of the electronic equipment, especially sharp sounds and noises, so that users can obtain a better user experience.

[0079] In one embodiment, a vibration-damping protrusion 118 is provided on the outer peripheral wall of the vibration-damping sleeve 116 , and the vibration-damping sleeve 116 forms point contact or line contact with the inner wall of the motor bracket 113 through the vibration-damping protrusion 118 .

[0080] In this embodiment, the vibration damping sleeve 116 and the motor bracket 113 do not adopt a full contact structure, but a point contact or line contact structure, which can further block the vibration transmission path of the motor 112 during operation, reduce the vibration transmission from the motor 112 to the motor bracket 113, and achieve a more effective vibration reduction and noise reduction effect.

[0081] In one embodiment, the vibration-damping protrusion 118 includes a plurality of vibration-damping convex points, which are divided into at least two groups. Each group of vibration-damping convex points is arranged at intervals along the circumference of the vibration-damping sleeve 116 , and at least two groups of vibration-damping convex points are arranged at intervals along the axial direction of the vibration-damping sleeve 116 .

[0082] In one embodiment, the vibration-damping protrusion 118 includes a plurality of vibration-damping protrusion rings, which are arranged at intervals along the axial direction of the vibration-damping sleeve 116 .

[0083] At least two sets of vibration-damping protrusions 118 are arranged at intervals along the axial direction of the vibration-damping sleeve 116 , which can improve the stability of the matching structure between the vibration-damping sleeve 116 and the motor bracket 113 , thereby improving the stability and reliability of the installation structure of the motor 112 .

[0084] In one embodiment, the hardness of the vibration-damping sleeve 116 is 25 to 35 degrees Shore hardness. The hardness of the vibration-damping sleeve 116 is also an important factor affecting the noise of the motor, and has a great influence on the transmission of vibration. When the hardness of the vibration-damping sleeve 116 is too large, the vibration-damping effect will be average. This embodiment limits the hardness range of the vibration-damping sleeve 116 to 25 to 35 degrees Shore hardness, which can ensure that the vibration-damping sleeve 116 effectively supports the motor 112 while enabling the motor 112 to obtain a better vibration-damping effect and a better noise reduction effect. In one embodiment, the hardness of the vibration-damping sleeve 116 is 30 degrees Shore hardness.

[0085] In one embodiment, the vibration-damping sleeve 116 and the motor bracket 113 , as well as the vibration-damping sleeve 116 and the fan 110 , are both transition fit or interference fit.

[0086] In this embodiment, each component of the fan assembly 100 adopts a transition fit or an interference fit, which can avoid the use of a clearance fit between these components to cause a wire gap, thereby avoiding noise and murmur caused by vibration.

[0087] In one embodiment, the fan assembly 100 includes a fan 110 and a motor bracket 113. The fan assembly 100 also includes a fluid channel 114 extending along the second axis 3. The motor bracket 113 is arranged on the air duct wall of the fluid channel 114. The central axis of the fan 110 is parallel to or coincides with the second axis 3. The fan 110 and the motor bracket 113 are molded into one piece by glue pouring.

[0088] In this embodiment, the motor 112 and the motor bracket 113 of the fan 110 are formed into one piece by glue pouring, which can ensure the stability and reliability of the matching structure between the motor 112 and the motor bracket 113. At the same time, the motor 112 and the motor bracket 113 are connected by glue pouring, and the glue pouring between the motor 112 and the motor bracket 113 can be used to reduce vibration and noise.

[0089] In one embodiment, in a cross section perpendicular to the first axis 2 , the accommodating cavity 404 is U-shaped, a groove bottom 4041 of the accommodating cavity 404 is disposed close to the first axis 2 , and an opening 4042 of the accommodating cavity 404 is disposed away from the first axis 2 .

[0090] In this embodiment, the cross-section of the accommodating chamber 404 is set to be U-shaped, and the groove bottom 4041 of the U-shaped accommodating chamber 404 is set close to the first axis 2, and the opening is set away from the first axis 2. When the airflow enters the accommodating chamber 404, it can reach the other side of the bristles under the guiding action of the arc-shaped structure of the groove bottom 4041. In this way, after the airflow enters the accommodating chamber 404 from the drainage outlet 405, it will be divided into two parts. One part will blow directly toward the side of the drainage outlet 405 to dry the bristles, and then turn downward and flow out from the fluid outlet 402. The other part will be guided along the arc-shaped structure of the groove bottom 4041 to reach the other side of the bristles to dry the other side of the bristles. This is equivalent to drying the side with the largest bristle area from both sides of the bristles at the same time, which can more effectively improve the drying efficiency of the bristles, and can further reduce the thickness of the bristles that the airflow needs to penetrate during the drying process of the bristles, thereby achieving more thorough drying of the bristles and improving the drying effect of the bristles.

[0091] In one embodiment, the middle cavity 400 includes a fluid channel 114 and a mounting cavity 115 . The fluid channel 114 and the mounting cavity 115 are separated by an air duct wall 406 extending along the second axis 3 . The fluid inlet 204 and the drainage outlet 405 are both connected to the fluid channel 114 .

[0092] In this embodiment, the middle cavity 400 is divided, and the air duct wall 406 is used to isolate the fluid channel 114 from the installation cavity 115, so that the fluid channel 114 forms a closed channel that is completely disconnected from the installation cavity 115. The fluid channel 114 is connected to the accommodating cavity 404 only through the fluid inlet 204 and the drainage outlet 405, so that the airflow cannot enter the installation cavity 115 during the flow along the fluid channel 114, thereby preventing water vapor in the airflow from entering the installation cavity 115 and causing corrosion to the components in the installation cavity 115.

[0093] In this embodiment, the fluid channel 114 serves as both a part of the central cavity 400 and a part of the fan assembly 100 , thereby isolating the components of the fan assembly 100 located in the fluid channel 114 from the components located in the installation cavity 115 .

[0094] In one embodiment, a battery 501 is installed in the installation cavity 115 , and in a cross section perpendicular to the first axis 2 , a length direction of the accommodating cavity 404 is perpendicular to a central axis of the battery 501 .

[0095] In this embodiment, the length direction of the accommodating cavity 404 is perpendicular to the central axis of the battery 501, so that the length extension direction of the accommodating cavity 404 can be perpendicular to the length extension direction of the battery 501. In this way, the length extension direction of the accommodating cavity 404 and the length extension direction of the battery 501 are not on the same straight line, so that the accommodating cavity 404 and the battery 501 can both be set in a position with a larger space in the middle cavity 400. While meeting the setting requirements of the accommodating cavity 404 and the battery 501, the setting positions of the accommodating cavity 404 and the battery 501 are optimized to make full use of the space in the middle cavity 400, reduce the size of the whole machine as much as possible, and realize the miniaturization of the brush head care container.

[0096] Because the length of the accommodating chamber 404 extends perpendicularly to the length of the battery 501, space is created on both sides of the accommodating chamber 404, facilitating the installation of other components. In one embodiment, the fan assembly 100 is disposed on one side of the accommodating chamber 404 and is located within the area enclosed by the accommodating chamber 404 and the battery 501.

[0097] In one embodiment, a PCB board 801 is further disposed in the installation cavity 115 , and the PCB board 801 and the fan 100 are respectively disposed on two opposite sides of the accommodating cavity 404 .

[0098] In one embodiment, a PCB board 801 is further disposed in the mounting cavity 115. The PCB board 801 and the fan assembly 100 are respectively disposed on two opposite sides of the accommodating cavity 404. A contact switch 802 is disposed on the PCB board 801 to facilitate control of the motor 112 and other components.

[0099] In this embodiment, the accommodating cavity 404 is arranged at the middle position corresponding to the length direction of the battery 501, and installation space is formed on both sides of the accommodating cavity 404. The fan assembly 100 is arranged in the installation space on one side of the accommodating cavity 404, and the PCB board 801 is arranged in the installation space on the other side of the accommodating cavity 404, so that the structural layout of the components is more reasonable and the overall structure is more compact.

[0100] The brush head care container further includes a lens assembly, wherein the lens assembly includes a lens 702, a lens cover 701 and a UVC disinfection lamp.

[0101] The lens assembly is installed between the middle shell 401 and the bottom shell 901 , wherein the lens 702 is installed on the lens cover 701 and is installed on the bottom shell 901 through the lens cover 701 . The UVC disinfection lamp disinfects the brush head 601 through the lens 702 .

[0102] In one embodiment, the upper shell 102 is hinged to a side of the side wall 201 away from the opening 403 via a rotating shaft 103 , which can facilitate opening or closing the accommodating cavity 404 so as to place or remove the brush head 601 on or from the brush head holder 301 .

[0103] In one embodiment, a skylight 101 is provided in the middle of the upper shell 102. The upper shell 102 is provided with the skylight 101, wherein the skylight 101 is nested on the upper shell 102.

[0104] In one embodiment, the brush head care container also includes a brush head holder 301, which is detachably mounted on the middle shell 401. The brush head holder 301 is located in the accommodating cavity 404. The brush head holder 301 includes a placement groove 302 for installing the brush head assembly, and the placement groove 302 is arranged corresponding to the opening 403.

[0105] Since the brush head holder 301 is detachable, when cleaning is needed, the brush head holder 301 can be removed from the shell, and then the brush head holder 301 can be cleaned and dried before being installed on the shell. This will not have an adverse effect on the electronic components in the shell, and can ensure that the brush head holder 301 is clean and dry, making it convenient to clean the brush head holder 301, and effectively avoiding problems such as residual toothpaste stains and mold on the brush head holder 301.

[0106] Since the brush head holder 301 can be removed, the cleaning of the accommodating cavity 404 will not be affected by the brush head holder 301, and the operation is simpler and more convenient. It can be cleaned directly by wiping, so that the brush head care container can be kept clean and dry as a whole, improving the problems of the brush head care container being difficult to clean, easy to leave toothpaste stains, water stains, and the resulting mold, thereby improving the usability and comfort of the brush head care container.

[0107] In one embodiment, the brush head holder 301 is snap-fitted to the middle shell 401. This snap-fitting arrangement allows for the brush head holder 301 to be mounted on the middle shell 401, resulting in a simple structure, convenient operation, and quicker installation and removal. This makes cleaning the brush head holder 301 easier, reduces operational difficulty, and improves user convenience.

[0108] The clamping connection between the brush head holder 301 and the middle shell 401 can be achieved directly by utilizing the structures on the brush head holder 301 and the middle shell 401, without the need to set up additional components, so the cost of parts is lower.

[0109] In one embodiment, the detachable connection between the brush head holder 301 and the middle shell 401 may also be a screw connection or a pin connection.

[0110] In one embodiment, a laterally extending hook is provided on the inner side of the main body 1, and a slot 304 is provided at the end of the brush head holder 301 close to the main body 1. The slot 304 is clamped on the hook. The slot 304 extends from the bottom of the brush head holder 301 and extends a preset length along the first axis 2 to form a stop surface at the end of the slot 304 to stop the hook.

[0111] In this embodiment, a hook extends laterally from the main body 1, and the brush head holder 301 can be directly engaged with the hook via a slot 304, thereby achieving the positioning and installation of the brush head holder 301 on the main body 1. The slot 304 extends from the bottom of the brush head holder 301 but does not pass through the top of the brush head holder 301. Therefore, the slot 304 can form a stop surface on the side near the top of the slot. When the slot 304 is engaged with the hook, the brush head holder 301 slides down relative to the hook under the action of the slot 304. When it slides down to the position where the stop surface contacts the hook, the stop surface stops the brush head holder 301 and hangs on the hook and does not slide down further, effectively limiting the downward movement of the brush head holder 301. On the one hand, it accurately defines the hook position of the brush head holder 301 on the hook, and on the other hand, it effectively prevents the brush head holder 301 from sliding off the hook, thereby ensuring the stability and reliability of the clamping structure of the brush head holder 301 on the hook.

[0112] In one embodiment, the brush head support 301 has a support groove 303 facing the first axis 2 . The support groove 303 is located on both sides of the placement groove 302 . The width of the support groove 303 decreases in a direction away from the first axis 2 .

[0113] In one embodiment, the brush head holder 301 is an elastic structure, and the brush head holder 301 and the hook are in interference fit.

[0114] In this embodiment, the brush head holder 301 is designed as an elastic structure, and the brush head holder 301 and the hook are interference fit. The elastic deformation force of the brush head holder 301 can be used to press the hook, so that a stable fit is formed between the brush head holder 301 and the hook, preventing the brush head holder 301 from moving relative to the hook after being installed on the hook, thereby improving the stability and reliability of the installation structure.

[0115] In addition, the brush head holder 301 adopts an elastic structure, and after the brush head 601 is installed on the brush head holder 301, the brush head holder 301 can be used to clamp and fix the brush head 601, so that the brush head 601 can be stably installed on the brush head holder 301.

[0116] In one embodiment, the shell is a wall-mounted structure. When the shell is hung on the wall, the opening 403 is located at the bottom of the shell. The brush head holder 301 also includes a supporting part, which is located at the top of the brush head holder 301. The toothbrush is suspended on the brush head holder 301, and the brush head 601 is supported by the top of the brush head holder 301.

[0117] In this embodiment, the shell is provided with a structure suitable for wall hanging, such as a hook or a hanging hole, so that the brush head care container is in a wall-hanging state when it is in use. At this time, the opening 403 is located at the bottom of the shell, the top of the brush head holder 301 is the side away from the opening 403, and the bottom of the brush head holder 301 is the side close to the opening 403. The top of the brush head holder 301 here refers to the top of the brush head holder 301 when the shell is in a wall-hanging state, which is different from the top and bottom of the placement groove 302 of the brush head holder 301. The top and bottom of the placement groove 302 are relative to the placement groove 302, with the bottom of the placement groove 302 as the bottom and the groove position as the top, not the top and bottom of the brush head holder 301 when it is in use. The references between the two are different, so there is no contradiction.

[0118] In one embodiment, the support portion includes a downwardly recessed support groove 303 , and the width of the support groove 303 decreases from top to bottom.

[0119] In this embodiment, the width of the support groove 303 decreases from top to bottom, and can form a structure that gradually shrinks from top to bottom. When the brush head 601 is installed on the brush head holder 301, the neck of the brush head 601 will be stuck in the support groove 303 and supported by the support groove 303. Since the width of the support groove 303 decreases from top to bottom, the brush head 601 can fall into the support groove 303 under the action of gravity and be limited by the support groove 303, so that the support of the brush head 601 by the support groove 303 is more stable. Since the width of the support groove 303 decreases from top to bottom, it coincides with the change of the neck structure of the brush head 601, so that the two have better adaptability and the matching structure is more stable.

[0120] In one embodiment, the support groove 303 includes multiple different curved surfaces, the curvatures of which decrease from top to bottom, and adjacent curved surfaces are connected by arc-shaped transitions. In this embodiment, to accommodate multiple brush heads 601 so that they can be stably placed on the brush head holder 301, the outer curved surfaces of multiple commonly used brush heads 601 are superimposed and then smoothly combined. Each brush head has a different width due to the outer curved surface, forming a curved surface that gradually narrows. Therefore, when different brush heads 601 are placed on the brush head holder 301, they will contact the curved surface at different heights depending on their width, thus achieving a tight hang without shaking.

[0121] The assembly order of the brush head care container is as follows: the skylight 101 is put on the upper shell 102, and the rotating shaft 103 is inserted into the rotating shaft hole of the upper shell 102; the lens 702 is installed in the lens sleeve 701, and then installed on the middle shell 401; the motor 112 is inserted into the motor bracket 113, and then the fan blade 111 is installed on the motor shaft, and then the entire assembly is screwed to the middle shell 401; then the PCB board 801 and the battery 501 are placed in the reserved position of the middle shell 401, and then the entire middle shell 401 is installed into the side wall 201; then the bottom shell 901 is covered, the screws are tightened, and the cover plate 902 is covered; finally, the brush head bracket 301 is inserted into the middle shell 401, and the dust plug 202 is inserted into the avoidance opening 203 on the side wall 201 to complete the assembly of the whole machine.

[0122] During the use of the brush head care container, the air duct design adopts the form of right air inlet and bottom air outlet; the wind blows in from the right through the fluid channel 114 where the battery holder is located, and blows the side of the bristles from the fluid outlet 402, which is the side with the largest bristle area. At the same time, the wind contacts and rebounds against the U-shaped inner wall to form a downward flow, which can effectively drive the moisture on the bristles to flow out from the fluid outlet 402 downward with gravity; at the same time, in the fluid channel 114, the motor 112 drives the fan blades 111 to rotate to generate a large amount of wind with a certain wind pressure, which penetrates the bristles from the side and forms a circulation around the surface of the bristles, thereby accelerating the rapid evaporation of moisture in the bristles and realizing rapid drying of the bristles. The dry bristles avoid the growth of bacteria.
