Technical Field

[0001] This utility model relates to the field of daily necessities technology, and more specifically, to a toothbrush holder with a drying function. Background Technology

[0002] In daily life, cleaning and drying toothbrushes are crucial for maintaining oral hygiene. However, traditional toothbrush holders typically only offer basic storage and cannot effectively address the issue of residual moisture after toothbrush use. A damp environment easily breeds bacteria and mold, affecting the hygiene of the toothbrush and posing a potential threat to the user's health. While some existing toothbrush holders attempt to improve this by adding ventilation or simple drainage designs, the effects are limited, especially in high-humidity environments where rapid drying and effective sterilization are difficult to achieve. Furthermore, current technology lacks devices for effectively sterilizing toothbrushes, resulting in a large number of bacteria remaining on the toothbrush surface. These problems are particularly pronounced when multiple people share a toothbrush holder, easily leading to cross-infection. Existing drying devices often suffer from complex structures, high energy consumption, and low drying efficiency, and most lack temperature control, potentially damaging toothbrush materials due to overheating. Additionally, the installation structure of existing toothbrush holders generally presents difficulties in disassembly and cleaning, hindering daily maintenance. Utility Model Content

Detailed Implementation

[0015] Combination Figures 1 to 3 As shown, this embodiment provides a toothbrush holder with a drying function, including a housing with a placement cavity 3 formed thereon; it also includes a fan assembly 5 disposed within the housing and a toothbrush holder 8 mounted outside the placement cavity 3; wherein, an air duct outlet 6 is formed at the placement cavity 3; an air duct 4 is formed within the housing, connecting the fan assembly 5 and the air duct outlet 6, to guide the air blown by the fan assembly 5 through the air duct outlet 6 to the placement cavity 3. By providing an airflow channel connecting the fan assembly 5 and the air duct outlet 6 inside the housing, the airflow generated by the fan can directly act on the toothbrush surface through a specific path.

[0016] The housing includes a lower shell 1 and an upper shell 2, which are the supporting structures for carrying various functional components. It can be made of injection-molded ABS plastic, with an internal cavity forming the installation space for the equipment. During installation, the upper shell 2 can be fixed below the mirror cabinet, with the lower shell 1 facing downwards to ensure unobstructed airflow. The placement cavity 3 is the area used to accommodate toothbrush heads; its depth can be set greater than the maximum width of the toothbrush head to ensure airflow coverage while providing space for assembling and disassembling the toothbrush holder 8. The fan assembly 5 is the power device that generates forced airflow; a DC centrifugal fan can be selected. The air outlet 6 is the airflow output port located inside or beside the placement cavity 3; it can use a porous grille structure to evenly disperse airflow and prevent flying insects from entering.

[0017] When the fan assembly 5 is activated, outside air enters the housing through the air inlet, is accelerated by the air duct 4, and is then concentrated and ejected from the air duct outlet 6. This directional airflow covers the toothbrush placement area, accelerating the moisture evaporation process. The relative position of the toothbrush holder 8 and the air duct outlet 6 is calculated to ensure that each toothbrush receives uniform airflow coverage. The enclosed air duct 4 in this design isolates external moisture interference, and the airflow drying penetrates deep into the gaps between the toothbrush bristles, allowing for rapid evaporation of moisture from the toothbrush surface, effectively inhibiting microbial growth. Even when multiple toothbrushes are drying simultaneously, each toothbrush maintains independent airflow coverage, preventing cross-contamination.

[0018] In this embodiment, the housing includes a lower shell 1 and an upper shell 2. The upper shell 1 is provided with several air duct outlets 6. The lower shell 1 and the upper shell 2 form an installation space for the fan assembly 5, which is connected to the air duct outlets 6. The lower shell 1 refers to the cover component located at the bottom of the housing, which can be made of injection-molded plastic and is used to support the air duct outlets 6 and form the appearance of the housing. The upper shell 2 refers to the upper housing component that cooperates with the lower shell 1. It can be connected to the lower shell 1 by clips or screws to form a sealed installation space to accommodate the fan assembly 5. The toothbrush holder can be installed as a whole under the mirror cabinet through the upper shell 2. The air duct outlets 6 refer to the airflow channels provided on the lower surface of the upper shell 1. They can be an array of circular holes with a diameter between 2-5 mm, used to evenly guide the airflow generated by the fan to the toothbrush placement area below. The installation space refers to the cavity structure formed after the lower shell 1 and the upper shell 2 are combined. It can be supported by internal ribs to fix the fan assembly 5 and construct the airflow transmission path. The lower shell 1 and upper shell 2 are modularly assembled through a split structure, forming a sealed installation space when closed. An axial fan can be fixed within this space. The airflow generated by the fan during operation flows through the installation space and the air duct outlets 6, exiting from multiple air duct outlets 6 distributed on the surface of the upper shell 1. For example, three rows of air duct outlets 6 can be provided at the bottom of the upper shell 1, each row containing four to six grid-like strip air outlets, allowing the airflow to cover different height areas of the toothbrush holder 8. Preferably, a guide slope is provided inside the installation space to guide the axial airflow generated by the fan to each air duct outlet 6.

[0019] In a preferred embodiment, a heating device 11 is provided at each air duct outlet 6. The heating device 11 is connected to a control circuit, and the control circuit is connected to a temperature sensor to control the heating temperature of the heating device 11.

[0020] The heating device 11 is a device for generating heat, specifically a heating wire or an electrothermal nickel-chromium alloy. Its function is to heat the airflow and output it to the placement chamber 3, thereby accelerating the evaporation of moisture on the toothbrush surface by increasing the air temperature. Preferably, an electrothermal nickel-chromium alloy combined with a control circuit is used to achieve rapid heating. The control circuit is a circuit module used to adjust the output power of the heating device 11, specifically a microcontroller combined with a power adjustment element. Its function is to dynamically adjust the operating state of the heating device 11 based on the feedback signal from the temperature sensor. The temperature sensor is an electronic component used to detect the ambient temperature, specifically a thermistor or an infrared temperature measurement module. Its function is to monitor the airflow temperature at the air duct outlet 6 in real time and transmit the data to the control circuit. In this embodiment, the heating temperature of the heating device 11 is controlled at approximately 60~70℃.

[0021] When the fan assembly 5 is activated, airflow enters the heating element 11 area through the air duct 4 and is heated, then blows from the air duct outlet 6 onto the toothbrush inside the placement cavity 3. A temperature sensor continuously collects temperature data at the outlet. When the detected temperature exceeds a preset threshold, the control circuit automatically reduces the power of the heating element 11; when the temperature is below the threshold, the power is increased to maintain a stable hot air output. This achieves a temperature-controlled drying process, avoiding damage to the toothbrush material from high temperatures while ensuring drying efficiency. It should be noted that the electrothermal nickel-chromium alloy is located on the side of the air duct outlet 6 near the air duct 4 and connected to the control circuit board 13, which in turn connects to the control circuit within the control circuit board 13. Each air duct outlet 6 has one heating element 11. The placement of the electrothermal nickel-chromium alloy on the side of the air duct outlet 6 near the air duct 4 prevents accidental burns from user contact. Combination Figures 4 to 6 As shown, in this embodiment, the toothbrush holder 8 includes an L-shaped plate with a plurality of toothbrush placement slots 81, and the L-shaped plate is detachably mounted on the housing.

[0022] The L-shaped plate refers to an L-shaped support structure, which can be made of injection-molded plastic. Its longitudinal portion supports the toothbrush head, while its transverse portion conforms to the housing to form a support. The toothbrush placement slot 81 refers to a groove structure formed on the L-shaped plate, which can be implemented using an arc-shaped recess design. The depth and curvature of each groove are configured to accommodate toothbrush heads of different sizes. The detachable installation means that the L-shaped plate is connected to the housing via a mechanical structure, which can be achieved using a snap-fit ​​or sliding rail structure, allowing the user to detach the L-shaped plate. Specifically, a mounting member 9 is provided inside the housing, an elastic plate is formed on the mounting member 9, a first protrusion 92 is provided on the elastic plate, and a snap-fit ​​space 10 with an opening is formed between the elastic plate and the housing to expose the placement cavity 3; an L-shaped fastener 82 is formed on the L-shaped plate, the L-shaped fastener 82 has a second protrusion 83, the L-shaped fastener 82 is adapted to be inserted into the snap-fit ​​space 10, and the first protrusion 92 is adapted to be locked at the rear end of the second protrusion 83 to restrict the L-shaped fastener 82 from exiting the snap-fit ​​space 10.

[0023] The mounting component 9 refers to the support structure fixed inside the housing to support the elastic plate and the limiting part 93. Specifically, it can be implemented using a one-piece frame molded from plastic injection molding, providing a stable mounting base for the elastic plate. The elastic plate is a thin-walled structure with deformation capability, achieving a detachable connection with the L-shaped fastener 82 through the elasticity of the material itself. The first protrusion 92 is a raised structure on the surface of the elastic plate, specifically designed as a triangular cross-section protrusion, used to create mechanical interference with the second protrusion 83. The snap-fit ​​space 10 is a cavity formed by the elastic plate and the inner wall of the housing, with its opening direction aligned with the installation path of the toothbrush holder 8, facilitating the insertion and guidance of the L-shaped fastener 82. The L-shaped fastener 82 is a right-angled bend structure on the bottom surface of the horizontal portion of the toothbrush holder 8, specifically injection molded from ABS material, forming the second protrusion 83 to achieve a locking fit with the elastic plate.

[0024] Specifically, when installing the toothbrush holder 8, the operator aligns the vertical section of the L-shaped fastener 82 with the opening of the locking space 10 and pushes it in at an angle. As the L-shaped fastener 82 penetrates deeper into the locking space 10, the front inclined surface of the second protrusion 83 contacts the first protrusion 92 and compresses the elastic plate, causing elastic deformation. After the second protrusion 83 completely passes the first protrusion 92, the elastic plate returns to its original position, causing the first protrusion 92 to abut against the rear end plane of the second protrusion 83, forming a mechanical lock. For disassembly, simply press the exposed part of the elastic plate to disengage the first protrusion 92 from the second protrusion 83, and then pull the L-shaped fastener 82 out in the opposite direction. Through the dynamic cooperation between the elastic plate and the protrusion, reliable locking is ensured while tool-free quick assembly and disassembly are achieved, resolving the contradiction between the stability and ease of maintenance of the toothbrush holder 8. This avoids accidental detachment due to vibration or accidental contact, and simplifies the disassembly process during daily cleaning and maintenance, allowing for convenient deep cleaning of the toothbrush holder while maintaining the normal operation of the drying function module.

[0025] In one embodiment, a limiting part 93 is provided at the other end of the mounting member 9, which is adapted to fasten the circuit board 13 into the housing. The limiting part 93 of the mounting member 9 enables tool-free quick assembly and disassembly of the circuit board 13, while avoiding the risk of aging and failure caused by adhesive bonding. It effectively solves the problem of poor contact caused by vibration inside the housing of the circuit board 13, ensuring a stable power supply to the heating device 11 and the fan assembly 5. The integrated design of the limiting part 93 and the mounting member 9 simplifies the manufacturing process, reduces the number of parts, and provides a reversible assembly and disassembly solution for the maintenance of the circuit board 13, avoiding repair damage caused by traditional fixing methods.

[0026] In a preferred embodiment, an ultraviolet (UV) lamp assembly 12 is provided at the front end of the placement cavity 3. The UV lamp assembly 12 is configured to irradiate the toothbrush placed on the toothbrush holder 8 from front to back. The UV light sterilizes the toothbrush surface. The UV lamp assembly 12 is connected to a control circuit and can be set to start on a timer or triggered by a humidity sensor signal. When the toothbrush is placed on the toothbrush holder 8, the UV lamp assembly 12, once activated, covers the entire toothbrush head and bristle area, destroying microbial structures through UV irradiation. This solution, by using the rearward irradiation method of the front-end UV lamp assembly 12, avoids the problem of UV light escaping from the placement cavity, simultaneously achieving the dual functions of drying and sterilization during toothbrush storage.

[0027] The housing has an air inlet corresponding to the fan assembly 5, and a filter plate 7 is installed at the air inlet. The air inlet is an opening on the surface of the housing for external air to enter, which can be implemented as a circular or rectangular hole, and its position corresponds to the air intake end of the fan assembly 5 to ensure the continuity of the airflow path. The filter plate 7 is a porous structural component installed at the air inlet, which can be implemented by densely arranging air intake holes on the housing, using nylon mesh, or by using a filter plate 7 structure, to prevent dust, hair, and other foreign objects from entering the housing.

[0028] Through the above technical solution, this utility model solves the problems existing in the toothbrush holder and meets users' needs for hygiene and convenience.

[0029] It should be understood that the above are only preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the scope of the present utility model are protected by the present utility model.

[0030] The accompanying drawings used in the above description of the embodiments only show some embodiments of the present invention and should not be regarded as a limitation of the scope.
