Abstract
Description
Technical Field
[0001] This utility model relates to the field of swimming cap technology, and in particular to a luminous swimming cap. Background Technology
[0002] With the popularization of swimming and the increasing demand for water safety protection, luminous swimming caps with warning functions have gradually become a hot topic in market research. Current luminous swimming caps usually have the light-emitting components directly fixed on the surface of the cap body, or the light cover is installed through a simple buckle structure, but there are still many defects in practical applications.
[0003] Firstly, regarding the ease of disassembling and assembling the lampshade, traditional light-up swimming caps often use glue to connect the lampshade to the cap body. This glue-attached structure provides a one-time fixation, meaning that when the light-emitting unit malfunctions or the lampshade ages and breaks, it cannot be disassembled and replaced individually, requiring the entire cap to be scrapped. This not only increases the user's cost but also prevents the replacement with other cartoon-shaped lampshade structures, reducing the fun of wearing the cap. Other caps use a threaded locking structure, requiring tools to tighten, which is inconvenient in wet swimming conditions. Furthermore, the screws at the threaded connection are prone to rust and jamming due to water residue, further reducing disassembly and assembly efficiency.
[0004] Secondly, regarding waterproof sealing performance, the existing products have a relatively simple sealing structure design, mostly relying solely on the contact between the lampshade and the end face of the mounting base to achieve a seal. The sealing surface is prone to gaps due to head shaking and water pressure impact, causing water to seep into the interior, resulting in short circuits in the light-emitting unit and burnout of control components. Although some products have added sealing rings at the connection points, the compatibility between the sealing rings and the assembly structure is poor, and they are prone to aging and falling off after long-term use, failing to form a continuous and stable sealing effect, which seriously affects the service life and safety of the swimming cap. Therefore, the above problems need to be improved and optimized. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a luminous swimming cap.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A luminous swimming cap includes a swimming cap body, a plurality of luminous units disposed on the swimming cap body, and a control unit for controlling the switching of the luminous units, and also includes a lampshade that is detachably connected to the luminous units via a support member.
[0008] Preferably, the support includes a base, on which a ring column is provided, and multiple ribs are provided on the outer side of the ring column.
[0009] Preferably, the annular column is a hollow structure, and the interior is used to house the light-emitting unit, the control unit, and the power supply that provides power to them.
[0010] Preferably, the top of the annular column has multiple slits, and multiple elastic plates are formed between the slits. The multiple elastic plates facilitate the placement of the light-emitting unit, the control unit, and the power supply within the hollow structure of the annular column.
[0011] Preferably, the inner side of the multiple elastic plates is provided with a baffle to prevent the control unit from falling off.
[0012] Preferably, the mounting part connecting the lampshade and the support is interference-fitted with the ring column, the material hardness of the mounting part is not greater than the material hardness of the ring column, and the height of the mounting part is greater than the height of the ring column.
[0013] Preferably, the inner side of the mounting part is provided with multiple raised rings that cooperate with the ribs, and the compression of the multiple raised rings and multiple ribs after installation forms a multi-level waterproof sealing mechanism.
[0014] Preferably, positioning posts are provided on both sides of the ring column on the base, and positioning sleeves adapted to the positioning posts are provided on both sides of the mounting part connecting the lampshade and the support. The hardness of the material of the positioning sleeve is not greater than that of the material of the positioning post.
[0015] Preferably, the swim cap body has an opening, and the ring column on the support passes through the opening and connects to the lampshade on the outside of the swim cap body.
[0016] Preferably, several light-emitting units and control units are electrically connected to the power supply. The light-emitting units are preset with green light, blue light and red light. The control unit includes a circuit board, a capacitor mounted on the circuit board for stabilizing the power supply voltage, a main control chip mounted on the circuit board and a vibration sensing switch mounted on the circuit board. The power supply is installed at the bottom of the circuit board to supply power to the electronic components.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. This utility model, through the interference fit between the support ring column and the lampshade mounting part, the high-coverage design of the mounting part, and the staggered fit between the ring column ribs and the mounting part protruding ring, forms a multi-level waterproof sealing mechanism, which prevents water intrusion in multiple ways. Combined with the flexible sealing characteristics of the silicone lampshade, it can effectively isolate the erosion of pool water and seawater, avoid short circuits of internal electronic components, and ensure the normal operation of the circuit even when the lampshade seal fails, thus greatly improving the reliability of the product in aquatic environments.
[0019] 2. This utility model enhances the structural rigidity of the support component through the outer ribs of the ring column, which are structurally stable and easy to assemble and maintain, preventing deformation caused by water pressure or external forces; the design of the mounting part with a lower hardness than the ring column enables tool-free rapid assembly; the detachable connection structure between the support component and the lampshade facilitates the individual replacement of damaged parts or the repair of the light-emitting unit and control unit, reducing maintenance costs; the dual installation scheme of the hollow structure of the ring column and the lampshade support ring can adapt to different production process requirements and improve design flexibility.
[0020] 3. This utility model uses RGB LED beads in the light-emitting unit, which can switch between green, blue and red colors. The green and blue light can serve as an indicator during daily swimming, reducing the risk of collisions in the water. Combined with the linkage control of the vibration sensor switch and the main control chip, the light automatically switches to a red flashing mode after the swimmer stops (10-30 seconds). The strong visual warning effect can quickly attract the attention of people around, buy time for rescue for drowning victims, and improve swimming safety.
[0021] 4. The lampshade in this utility model is made of soft silicone material, conforming to the contours of the head without any obvious foreign body sensation; the ribs can enhance the structural strength of the ring column, preventing it from deforming under assembly or water pressure, while increasing the contact area between the ring column and the mounting part, improving the tightness and sealing effect of the interference fit; and by using a small-volume button battery as the power source, it has the advantage of being lightweight and easy to wear, without increasing the burden of wearing it, and the capacity can support five minutes of warning flashing, reasonably controlling power consumption; the overall structural design reduces the damage of external impacts to electronic components and extends the product's service life.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0034] See Figures 1 to 9 As shown, the following are features of this utility model:
[0035] Example 1
[0036] Reference Figure 1 , Figures 3 to 8As shown, a luminous swimming cap includes a swimming cap body 1, several luminous units disposed on the swimming cap body 1, and a control unit for controlling the switching of the luminous units. The luminous units and control power supply both utilize existing publicly available technologies. It also includes a lampshade 3 detachably connected to the luminous units via a support member 2. The lampshade 3 can be round, square, or depict various animal, plant, or cartoon character images to enhance its appeal during use. The lampshade 3 is made of silicone, a material with excellent waterproof and corrosion-resistant properties, suitable for swimming pools, seawater, and other aquatic environments. It is also soft and elastic, cushioning impacts and preventing damage to the luminous units from external forces, while fitting snugly against the head without causing any foreign body sensation (TPRTPU / soft polyvinyl chloride can also be used). The support member 2 includes a base 201, on which a ring column 202 is disposed. Multiple ribs 203 are disposed on the outer side of the ring column 202. The ribs 203 enhance the structural strength of the ring column 202, preventing damage during assembly. Or deform during use; the mounting part 301 connecting the lampshade 3 and the support 2 is interference-fitted with the ring column 202. The material hardness of the mounting part 301 is not greater than that of the ring column 202, and the height of the mounting part 301 is greater than that of the ring column 202. The interference fit can achieve a gapless and tight connection. Combined with the height advantage of the mounting part 301, a triple sealing structure is formed, which effectively prevents water from entering the light-emitting unit and avoids short circuit failure. Moreover, the design of structural hardness difference makes the assembly smoother and can be completed without tools. In actual use, the base 201 in the support 2 is bonded to the outside of the swim cap body 1 with waterproof adhesive, and then the lampshade 3 is interference-fitted onto the ring column 202. The waterproof adhesive ensures that the base 201 and the swim cap body 1 are firmly connected and will not easily fall off even if repeatedly pulled in the water. At the same time, it prevents water from seeping at the bonding point. The detachable design makes it convenient to replace the damaged lampshade 3 or repair the light-emitting unit, reducing maintenance costs.
[0037] Reference Figure 9As shown, several light-emitting units and control units are electrically connected to the power supply. The light-emitting units are pre-set with green, blue, and red light (specifically, RGB LED beads). The RGB LED beads can achieve precise switching between multiple colors. Green and blue light meet the marking requirements during normal swimming, while red light is suitable for drowning warning scenarios, balancing practicality and safety. The control unit includes a circuit board, a capacitor mounted on the circuit board to stabilize the power supply voltage, a main control chip mounted on the circuit board, and a vibration sensor switch mounted on the circuit board. The power supply is located at the bottom of the circuit board to power the electronic components. The power supply can be a button battery or other power sources. When using a button battery, taking the CR1220 button battery as an example, the button battery can power the RGB LED beads and other electronic components in the light-emitting units. The capacitor can filter out high-frequency noise in the circuit, buffer voltage fluctuations, ensure stable operation of the main control chip and LED beads, and avoid light flickering or component damage caused by voltage surges. The CR1220 button battery is small in size (diameter 12...). It is 0.5mm thick and 2mm high, lightweight (approximately 0.8g), and easy to replace the power source (CR1220 button battery) when the power supply is unavailable, without adding to the burden of wearing the swim cap. In actual use, one end of the vibration sensor switch's pin is connected to the VCC power supply, and the other end is connected to the trigger signal terminal of the main control chip. When the swimmer wears the swim cap and moves, the head and the cap shake together, causing the ball inside the vibration sensor switch to roll, turning on the switch. The VCC signal is then transmitted to the main control chip, triggering the "green light". The flashing green light mode allows swimmers to be quickly identified in the water, reducing the risk of collisions. If a swimmer loses the ability to move after drowning (10-30 seconds), the ball resets, the switch disconnects, and the main control chip detects a "stationary signal," switching to the "red light flashing for 5 minutes" mode. The 10-30 second delay design avoids misjudging a brief period of stillness (such as breathing) as drowning, improving the accuracy of the warning. The strong visual impact of the flashing red light can quickly attract the attention of people around, buying time for rescue for the drowning victim.
[0038] Example 2
[0039] Reference Figures 2 to 8As shown, a luminous swimming cap includes a swimming cap body 1, several luminous units disposed on the swimming cap body 1, and a control unit for controlling the switching of the luminous units. It also includes a lampshade 3 detachably connected to the luminous units via a support member 2. The lampshade 3 is made of silicone. Silicone material possesses excellent waterproof sealing, flexibility, and weather resistance, preventing water from entering the luminous units and avoiding short-circuit failures. It also conforms to the head contour for comfortable wear and is resistant to the corrosion of pool disinfectants and seawater salt, extending the lampshade's service life. The support member 2 includes a base 201, on which a ring column 202 is disposed. Multiple ribs 203 are disposed on the outer side of the ring column 202. The ribs 203 enhance the structural rigidity of the ring column 202, preventing deformation during assembly or under water pressure. They also increase the contact area between the ring column 202 and the mounting part 301, improving the tightness of the interference fit. Furthermore, by increasing the contact area, they assist in heat dissipation of the luminous units, preventing heat accumulation that could lead to lamp decay.
[0040] Reference Figure 4 and Figure 6 As shown, the mounting part 301 connecting the lampshade 3 and the support 2 is interference-fitted with the annular column 202. The hardness of the material of the mounting part 301 is no greater than that of the material of the annular column 202, and the height of the mounting part 301 is greater than the height of the annular column 202. This hardness difference design allows the mounting part 301 to undergo adaptive deformation during assembly, ensuring the fit of the interference fit and reducing assembly difficulty. The height advantage of the mounting part 301 can form a covering and sealing structure, blocking water from seeping in through the fitting gaps and further improving the overall waterproof performance. An opening is reserved on the swim cap body 1. The size of the opening on the swim cap body 1 is smaller than that of the annular column 202. During installation, the base 201 in the support 2 is placed on the swim cap body 1. On the inner side, the support component 2 adopts an through-hole installation structure with an inner base 201 and an outer ring column 202. The edge of the opening of the swim cap body 1 can be used to form a limit to prevent the support component 2 from shifting or falling off during use, thereby improving connection stability and sealing effect. The ring column 202 on the support component 2 passes through the opening and connects to the lamp cover 3 on the outside of the swim cap body 1. It is further sealed and bonded to the swim cap body 1 with waterproof adhesive. The through-hole connection method combined with the sealing effect of the waterproof adhesive can not only achieve a firm connection between the support component 2 and the swim cap body 1, but also seal the assembly gap at the opening to prevent water seepage. At the same time, the detachable connection structure facilitates the subsequent inspection or replacement of the light-emitting unit, reducing maintenance costs.
[0041] Reference Figure 6As shown, positioning posts 206 are provided on both sides of the ring column 202 on the base 201. Positioning sleeves 302 adapted to the positioning posts 206 are provided on both sides of the mounting part 301 connecting the lampshade 3 and the support 2. The material hardness of the positioning sleeves 302 is not greater than that of the positioning posts 206. The matching structure of the positioning posts 206 and the positioning sleeves 302 can realize the precise pre-positioning of the support and the lampshade, reduce the alignment difficulty during assembly, and improve assembly efficiency. The hardness difference design allows the positioning sleeves 302 to undergo slight deformation during insertion, ensuring the tightness of the positioning connection and preventing loosening. The above structure facilitates... The positioning sleeve 302 and the positioning post 206 are stably inserted, and the two positioning posts 206 pass through the swim cap body 1 to further prevent them from falling off. It can also prevent the support 2 and the lamp cover 3 from rotating after connection, so as to avoid affecting the sealing connection between them. The anti-rotation design can prevent the support 2 and the lamp cover 3 from rotating relative to each other due to water flow impact, head shaking and other factors during use. It prevents the interference fit sealing structure from gapping due to rotation, ensuring the waterproof reliability of long-term use. At the same time, it prevents the light-emitting unit circuit from being pulled and damaged by rotation, and improves the overall stability of the product.
[0042] Example 3
[0043] Reference Figures 2 to 8 As shown, a luminous swimming cap includes a swimming cap body 1, several luminous units disposed on the swimming cap body 1, and a control unit for controlling the switching of the luminous units. It also includes a lampshade 3 detachably connected to the luminous units via a support member 2. The lampshade 3 is made of silicone. The silicone material combines waterproof sealing with flexibility, preventing pool water, seawater, and other water bodies from intruding into the luminous units and control unit, thus avoiding short circuits and damage to electronic components. It also conforms to the head contour, reducing discomfort during wear, and is resistant to the corrosion of disinfectants and salt in water, extending the lifespan of the lampshade 3. The support member 2 includes a base 201, on which a ring column 202 is disposed. Multiple ribs 203 are disposed on the outer side of the ring column 202. The ribs 203 enhance the structural strength of the ring column 202, preventing it from malfunctioning under assembly or water pressure. The mounting part 301, which connects the lampshade 3 and the support 2, is interference-fitted with the ring column 202. The hardness of the material of the mounting part 301 is no greater than that of the ring column 202, and the height of the mounting part 301 is greater than that of the ring column 202. The hardness difference design allows the mounting part 301 to undergo adaptive deformation during assembly, reducing assembly difficulty while ensuring the fit of the interference fit. The structural design of the mounting part 301 being greater than that of the ring column 202 can form a covering and sealing structure, which prevents water from seeping in from the fit gap, further improving the overall waterproof performance and ensuring the stable operation of electronic components.
[0044] Reference Figure 6 As shown, the annular column 202 is a hollow structure, housing the light-emitting unit, control unit, and power supply. The hollow structure allows for integrated storage of electronic components, eliminating the need for additional mounting cavities and simplifying the overall structure. Simultaneously, the annular column 202 provides protection, reducing external impacts on the electronic components and improving structural compactness. Multiple slits are formed at the top of the annular column 202, with multiple elastic plates 204 between them. These elastic plates 204 facilitate the insertion of the light-emitting unit, control unit, and power supply into the hollow structure of the annular column 202. The elastic plates 204 are deformable, opening outwards during assembly to provide space for the electronic components. After insertion, they automatically reset and clamp the components, enabling tool-free rapid assembly and improving production and maintenance efficiency. Inside the multiple elastic plates 204 are baffles 205 to prevent the control unit from detaching. The baffles 205 provide axial restraint for the inserted electronic components. To prevent components from detaching from the ring cylinder 202 due to head movement and water impact during swimming, ensuring the stability of the circuit connection, the light-emitting unit, control unit, and power supply can be installed inside the lampshade 3. A support ring is installed inside the lampshade 3 to fix the circuit board, which can be installed and fixed to the support ring inside the lampshade 3 using sealing screws or movable clips. The support ring provides a stable mounting reference for the circuit board, the sealing screw connection further improves the waterproof rating inside the lampshade 3, and the movable clips allow for quick assembly and disassembly of the circuit board. These two fixing methods adapt to the assembly needs of different scenarios. The above dual installation scheme facilitates the selection and adaptation of the circuit board to two installation methods, which can be flexibly adjusted according to production processes, cost budgets, or product functional requirements, improving the design flexibility and applicability of the product. At the same time, both installation methods effectively protect electronic components, ensuring the stable operation of the luminous swimming cap.
[0045] Example 4
[0046] Reference Figures 1 to 9A luminous swimming cap includes a swimming cap body 1, several luminous units disposed on the swimming cap body 1, and a control unit for controlling the switching of the luminous units. It also includes a lampshade 3 detachably connected to the luminous units via a support member 2. The lampshade 3 is made of silicone. Silicone material possesses excellent waterproof sealing, flexibility, and corrosion resistance, effectively preventing pool water and seawater from intruding into the luminous units, conforming to the head contour to reduce discomfort, and resisting the erosion of disinfectants and salt in water, thus extending the lifespan of the lampshade 3. The support member 2 includes a base 201 with a ring column 202. The mounting part 301 connecting the lampshade 3 to the support member 2 is interference-fitted with the ring column 202. The hardness of the mounting part 301 is no greater than the hardness of the ring column 202, and the height of the mounting part 301 is greater than the height of the ring column 202. This hardness difference design allows the mounting part 301 to undergo adaptive deformation during assembly, reducing assembly difficulty while ensuring a tight fit. The greater height of the mounting part 301... The structural design of the annular column 202 forms a primary sealing barrier, preventing water from seeping in from the mating end face and improving the basic waterproofing capability. Multiple ribs 203 are provided on the outer side of the annular column 202. These ribs 203 enhance the structural rigidity of the annular column 202, preventing deformation under water pressure or during assembly, while also increasing the contact area between the annular column 202 and the mounting part 301, improving the tightness of the interference fit. Multiple protrusions that mate with the ribs 203 are provided on the inner side of the mounting part 301. The ring 303, multiple convex rings 303, and multiple ribs 203, after installation and compression, form a multi-level waterproof sealing mechanism. The staggered fit structure of the ribs 203 and the convex rings 303 can form multiple physical barriers in the fit gap between the mounting part 301 and the ring column 202, so that the infiltrated water cannot enter the interior of the lamp cover 3 after being intercepted by multiple levels. Compared with a single interference fit sealing structure, the waterproof performance is exponentially improved. It can effectively prevent water from entering the lamp cover 3 and improve the sealing and waterproof performance of the internal electronic components.
[0047] Reference Figure 9As shown, several light-emitting units and a control unit are electrically connected to the power supply. The light-emitting units are pre-set with green, blue, and red light (specifically, RGB LED beads). The RGB LED beads enable precise switching between multiple colors. Green and blue light meet the needs of daily swimming for identification and decoration, while red light serves as a drowning warning signal, balancing practicality and safety. The control unit includes a circuit board, a capacitor mounted on the circuit board to stabilize the power supply voltage, a main control chip mounted on the circuit board, and a vibration sensor switch mounted on the circuit board. The power supply is located at the bottom of the circuit board to power the electronic components. The capacitor filters out noise from the circuit. High-frequency interference signals buffer power supply voltage fluctuations, ensuring that the main control chip and LED beads operate in a stable voltage environment, avoiding light flickering, component damage, or malfunction due to voltage surges; the circuit board adopts a waterproof circuit board structure, which will not cause damage to the circuit board and electronic components even if water accidentally enters the lamp cover 3; the waterproof circuit board can isolate moisture through its own waterproof coating or sealing structure, and can still ensure normal circuit operation in the extreme case of lamp cover 3 seal failure, avoiding short circuit and burnout of electronic components, greatly improving the product's fault tolerance and reliability, and reducing after-sales maintenance costs.
