Description

Technical Field

[0001] This application belongs to the field of sports equipment design technology, specifically relating to a multifunctional table tennis table for outdoor use. Background Technology

[0002] With the rapid development of the economy and society and the continuous improvement of comprehensive national strength, people's expectations for a better life are gradually increasing, and more and more people are cultivating and developing hobbies in their spare time. China is one of the world's sporting powers, and table tennis, as China's "national sport," has always been loved by countless enthusiasts. Every morning or evening, enthusiasts, carrying their table tennis bags and equipment, gather around these tables to enjoy the fun that table tennis brings. Table tennis has also brought health benefits to more and more people.

[0003] In recent years, outdoor ping-pong tables have become increasingly common in cities, towns, and rural areas. Compared to professional indoor ping-pong tables, outdoor tables are more frequently used by ordinary ping-pong enthusiasts, including non-professional athletes. Playing at professional indoor courts often requires driving or taking special transportation to a distant court and paying high fees. For ordinary citizens who simply want to play for fun, or students who are not part of a professional team, outdoor tables, which are closer to home, more accessible, cheaper, or even free, are often preferred for playing and recreation. Their purpose is not professional competition, but rather entertainment. This is precisely why outdoor ping-pong tables are widely being built in parks, squares, residential areas, commercial districts, schools, and rural areas, rather than indoor courts.

[0004] The existing outdoor table tennis table technology has problems including, but is not limited to, the following:

[0005] 1. Most existing outdoor table tennis tables do not have storage lockers. Table tennis enthusiasts have no place to put their backpacks, documents, clothing and other items. They usually have to put them on the table or the ground. Putting them on the table will affect the playing experience and take up the area of ​​the ping-pong ball landing surface. Putting them on the ground will make clothes and other personal items dirty. This usually causes people distress and is extremely inconvenient.

[0006] 2. Most existing outdoor table tennis table technologies do not include power generation, energy storage, and charging equipment. On the one hand, outdoor table tennis tables occupy a large area and are exposed to sunlight for extended periods, resulting in a significant amount of energy resources that have not been effectively stored and utilized. On the other hand, smartphones and other smart devices have become almost indispensable items, and table tennis enthusiasts are often forced to shorten their playing time or even cancel their games due to insufficient battery power. Sometimes, they also fail to pay attention to their phone's battery level and are unable to complete tasks such as showing their health code or making payments after the game due to insufficient power, causing them considerable inconvenience. In low-light environments such as at night, players are also forced to pack up and return, making them highly susceptible to environmental factors.

[0007] 3. In most existing outdoor table tennis table technologies, due to the variability and complexity of the application environment of outdoor tables, high fiber density boards made of wood cannot maintain a long lifespan in windy, sandy, rainy and snowy environments. Currently, some outdoor tables use steel plates, which are painted to prevent rust. However, as time goes by, the paint peels off and the resulting metal rust will affect the trajectory of the table tennis ball after it lands on the table, resulting in a poor playing experience.

[0008] 4. Most existing outdoor table tennis table technology lacks cooling or heating equipment. We often see professional athletes sweating profusely in air-conditioned courts during international table tennis competitions, frequently wiping the sweat from their heads, bodies, and hands. Outdoors, there is even less air conditioning or other temperature-regulating equipment. In the hot summer, table tennis enthusiasts often sweat profusely. Stagnant air, dry environment, and hot towels can cause athletes to suffer from unbearable heat and even heatstroke. In the cold winter, table tennis enthusiasts often crave a warm, damp towel to apply to their bodies and wipe themselves before and after playing. It is evident that sports towels are often indispensable for table tennis enthusiasts, but existing technology cannot meet these needs.

[0009] 5. In the hot summer, the surface temperature of most outdoor table tennis tables can sometimes reach very high levels after being exposed to the sun, posing a threat to the structural safety of the table and the health of the players. In the cold winter, the low temperature will cause the surface to freeze, and the expansion and contraction of the temperature will cause plastic deformation of some structures, accelerating aging, making the paint on the table surface easy to peel off, and accelerating oxidation.

[0010] The above only lists some common shortcomings of existing technologies. It is evident that current technologies cannot provide adequate sports services for outdoor table tennis enthusiasts. While science and technology are developing rapidly, with many cutting-edge technologies being widely applied in fields such as communications and smart terminals, some essential infrastructure and sports equipment for daily life remain unaffected by these advancements. For example, the outdoor table tennis tables widely available today are still very similar to those from decades ago, while people's needs for these facilities far exceed the scope of current technology. Improving the quality of life for people related to table tennis and its health requires new inventions and technological solutions for outdoor table tennis tables to address these shortcomings. Summary of the Invention

[0023] A storage battery cabinet, which has a cabinet door located in the longitudinal direction of the base and can be opened and closed from the outside. The inside is used to install the storage battery. Additionally, the storage battery cabinet is located in the center of the base, making two independent areas formed on the two transverse sides of the top surface of the base;

[0024] Four function boxes with the same appearance. The four function boxes are divided into two groups and are respectively located in the two independent areas, and are evenly distributed at the four corners of the base. Additionally, each function box is provided with a box door located in the longitudinal direction of the base and can be opened and closed from the outside.

[0025] Preferably, the storage battery cabinet is divided into four sub - cabinets. The four sub - cabinets are arranged side by side in pairs, and open slots are provided at the four corner positions where the four sub - cabinets contact each other as the wiring slots for each sub - cabinet. Additionally, each sub - cabinet is provided with the cabinet door; and

[0026] Each function box is divided into upper and lower sub - function boxes, and each sub - function box corresponds to a box door. Among them:

And among the plurality of thermocouple pairs on each side surface, the number of P - type semiconductors facing the inner cavity direction is greater than the number of N - type semiconductors, and the P-type semiconductors are arranged in a "艹" shape, and the N - type semiconductors surround the P - type semiconductors.

[0030] Preferably, in each of the functional boxes, the longitudinal width of the upper sub-functional box is smaller than the longitudinal width of the lower sub-functional box, such that the cross-section of each functional box is L-shaped; and

[0031] A gap exists between two functional boxes located within the same independent area on the same side. This gap, defined by the bottom surface of the sealing structure plate and the top surface of the base, forms an air duct. The outlet of the air duct is located at the lateral end face of the base. Simultaneously, each functional box has a cavity formed at its top due to the longitudinal width difference between its upper and lower sub-functional boxes. This cavity, defined by the bottom surface of the sealing structure plate, forms an air inlet. Furthermore, the air inlets formed on both longitudinal sides within the same independent area are connected to the air exhaust duct. The inlet of the air inlet is located at the lateral end face of the base, and the outlet of the air inlet serves as the inlet of the air exhaust duct.

[0032] The multi-functional ping-pong table also includes:

[0033] An intake fan is installed inside the intake duct, and its outlet faces the exhaust duct.

[0034] An exhaust fan is installed inside the exhaust duct, with its outlet facing laterally outward from the base. In addition, both the intake fan and the exhaust fan are connected to the battery via a fourth power controller.

[0035] Preferably, the multi-functional ping-pong table further includes:

[0036] Metal dust screens are respectively installed at the inlet of the air inlet duct and the outlet of the air outlet duct, wherein the outlet of the exhaust fan is directly opposite the metal dust screen at the corresponding position.

[0037] A baffle plate is installed at the outlet of the exhaust duct and is located on top of the metal dustproof mesh at the outlet to form a semi-enclosed space with the exhaust duct for air diversion.

[0038] Preferably, both the intake fan and the exhaust fan are linear fans; and

[0040] Preferably, the surface of the sealed structure plate is further provided with a battery connection box for transmitting the electrical energy generated by the solar panel to the storage battery for storage; and

[0041] The sealed structural plate has four evenly spaced load-bearing frustums at its top corners to support the solar panels located on top of it; and

[0042] A through hole is provided at the center of the sealing structure plate, corresponding to the wiring groove. A seepage-proof shielding plate is vertically arranged around the through hole. The height of the seepage-proof shielding plate is at least greater than the height of the phase change material layer after it has been completely heated, melted, and expanded.

[0043] Preferably, the bottom of the base is provided with a structural steel plate, a rubber shock-absorbing pad and a bottom load-bearing shell in sequence from top to bottom. In addition, two load-bearing bases are provided along the width or length direction at the bottom of the bottom load-bearing shell, and at least one structural reinforcing beam is provided between the load-bearing bases.

[0044] This application has at least the following beneficial technical effects:

[0045] 1) In the multifunctional ping-pong table of this application, the electrochromic glass provides the table with changes in the appearance color and transparency of the table surface. When the table is not in use, it is transparent, and sunlight and other light can pass through the transparent tempered glass cover and the electrochromic glass, shining on the solar panel to complete the photoelectric conversion. When the table is in use, the appearance of the electrochromic glass can be controlled to change to a dark blue frosted state, which can effectively reduce the glare caused to the player by the specular reflection of light and hardly affect the user's playing experience. In addition, the transparent tempered glass cover, as a protective cover for the ping-pong ball contact surface and the underlying structure, can have the characteristics of scratch resistance, explosion resistance, high temperature resistance, corrosion resistance, sturdiness, hardness, non-deformation, and high light transmittance. Furthermore, the solar panel can directly convert solar radiation energy into electrical energy using the photoelectric effect to power the various electrical devices in the ping-pong table or other user needs, without the need for additional power supply, making it more adaptable.

[0046] 2) In the multifunctional ping-pong table of this application, when the outside temperature is higher than the phase change temperature, the phase change material will gradually melt and absorb heat. When the outside temperature is lower than the phase change temperature, the phase change material will gradually solidify. This heat absorption and release process is reversible and can keep the temperature near the phase change temperature. In addition, the heating wire is evenly distributed in the phase change material, which can activate the auxiliary heating function to prevent the surface temperature of the table from getting too low. It can also be turned on at regular intervals in winter to clear the snow and frost on the surface of the table, which helps the solar panel to work stably.

[0047] 3) In the multi-functional ping-pong table of this application, the function box set under the table surface can effectively improve the user experience. In addition, the separate design of the towel temperature control cabinet and the semiconductor constant temperature box helps to maintain the cleanliness of the towels during the cooling or heating process, and also facilitates later maintenance and management. At the same time, since users usually have different temperature requirements for the towel temperature control cabinet and the semiconductor constant temperature box, the separate design can optimize the user experience and save energy to a certain extent, avoiding energy waste.

[0048] 4) In the multi-functional table tennis table of this application, the towel temperature control cabinet is installed on the upper part of the semiconductor constant temperature box, which makes it convenient for users to store and retrieve towels. In addition, this application includes two towel temperature control cabinets and two semiconductor constant temperature boxes, and the installation areas are located on the right side of the player's usual standing position on one side, which conforms to the habits of most table tennis players to take towels to wipe sweat, making it more convenient to use.

[0049] 5) In the multi-functional table tennis table of this application, semiconductor cooling and heating technology is used. The DC power provided by the battery in the energy storage battery cabinet supplies the energy required for the electron flow. On the one hand, it has low thermal inertia and fast cooling and heating time. On the other hand, it does not require any refrigerant, can work continuously, and is pollution-free and environmentally friendly. Furthermore, since there are no rotating parts, there is no rotational effect, and it will not produce vibration like compressor cooling, which will affect the playing experience of table tennis enthusiasts.

[0050] 6) In the multi-functional table tennis table of this application, the power strip cabinet can provide power to the user's electrical appliances, and all the power used comes from solar energy, which is environmentally friendly and zero-carbon, and also provides great help to table tennis enthusiasts.

[0051] 7) In the multi-functional ping-pong table of this application, the air intake and exhaust ducts (forming a T-shaped heat dissipation duct), metal dustproof mesh, wind deflector, and straight fan together constitute a heat dissipation structure, which can achieve efficient heat dissipation of internal components while generating natural wind that prevents direct blowing, promoting air movement around the table and providing users with a refreshing and comfortable user experience, without significantly affecting the trajectory of the ping-pong ball; in addition, the metal dustproof mesh can prevent insects, leaves and other impurities from entering the air duct and effectively reduce dust and grit, and the wind deflector can block part of the airflow located above the fan, preventing the harm caused by this part of the airflow blowing directly on the user;

[0052] 8) In the multi-functional table tennis table of this application, the design of the load-bearing base, bottom load-bearing shell, structural steel plate, load-bearing frustum, and structural reinforcing beam can provide structural support and reinforcement for this application. The rubber shock-absorbing pad can play the role of shock absorption and buffering, protecting the table, and also has the effect of controlling the noise generated by the electrical appliances in the table.

[0053] 9) The multifunctional table tennis table of this application perfectly solves the problems existing in the technology of outdoor table tennis tables. At the same time, it does not require any other external auxiliary installation conditions. It integrates power generation, energy storage and power supply systems. The energy used is clean, environmentally friendly and sustainable. In addition, this application can provide users with multifunctional and thoughtful services. It has a wide range of uses and can greatly enhance the outdoor sports experience of table tennis enthusiasts. It can attract more and more people to love sports and also help promote table tennis.

Detailed Implementation

[0065] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0066] It should be understood that the technical terms that may be involved in the description of this application, such as “center,” “longitudinal,” “lateral,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this application.

[0067] The following is in conjunction with the appendix Figures 1-10 The structure of the multi-functional outdoor ping-pong table of this application is further described in detail.

[0068] This application discloses a multifunctional table tennis table for outdoor use, including a base 1, a table surface 3 fixedly mounted on the base 1, and a net 15 mounted on the table surface 3. The table surface 3 includes a transparent tempered glass cover, an electrochromic glass 2, and a solar panel 25, which have the same outer contour shape and are laid out from top to bottom.

[0069] Specifically, a transparent tempered glass cover is installed on the top of the entire table tennis table, and the electrochromic glass 2 is tightly attached to the bottom of the transparent tempered glass cover. The transparent tempered glass cover has excellent scratch resistance, corrosion resistance, high temperature resistance, explosion resistance, stability, rigidity, and high light transmittance. In this embodiment, the thickness of the transparent tempered glass cover is preferably 8-12mm. If the thickness is too thin, it will be difficult to maintain a long lifespan in complex and changing outdoor environments. If the thickness is too large, on the one hand, light will be reflected through the mirror, causing glare to the player and affecting their playing experience; on the other hand, it will increase the unnecessary cost of the table tennis table. In addition, the transparent tempered glass cover should have sufficient elasticity on its upper surface, so that the rebound height of a ping-pong ball released from a height of 30cm is between 22-27cm. This provides sufficient protection for the electrochromic glass 2 and also provides the user with a stable, reliable, safe, and professional-level playing experience close to that of a major tournament table tennis table.

[0070] Electrochromic glass 2 utilizes the oxidation-reduction reaction of EC thin film material under an electric field, resulting in changes in light transmittance and reflectance. This allows for stable and reversible color changes under an applied electric field: it is transparent when energized, allowing almost uninterrupted sunlight to pass through and generate electricity on the solar panel 25; when de-energized, it exhibits a dark frosted state, significantly enhancing the contrast between the table tennis table and the ball, preventing glare that might obstruct the view of the ball. Furthermore, electrochromic glass 2 is typically manufactured using a laminated glass process. When the transparent tempered glass cover is shattered and the electrochromic glass 2 is impacted, the PVB interlayer in the electrochromic glass 2 firmly holds the glass fragments together, preventing them from scattering or falling, greatly reducing the chance of injury to nearby people.

[0071] Solar panel 25 is used to absorb sunlight passing through the transparent tempered glass cover and electrochromic glass 2, thereby generating photovoltaic power.

[0072] Furthermore, a protective shell for the solar panel 25 is provided around its perimeter. The protective shell is made of metal and is at the same vertical height as the solar panel 25. The two are tightly fitted together in the horizontal direction. This maximizes the area for solar power generation and prevents collisions and wear caused by external vibrations during the translation process of the solar panel 25. It can also reduce or even eliminate the adverse effects of external environment and force on the solar panel 25, such as damage and corrosion. In this embodiment, the protective shell is preferably made of high-strength aluminum alloy with a thickness of about 30mm. On the one hand, aluminum alloy is lightweight and strong, and this thickness provides sufficient protection. On the other hand, this material is not easily oxidized or corroded by the environment, and it is relatively inexpensive and widely available.

[0073] Furthermore, such as Figure 2 As shown, a sealing structure plate 14 is also provided between the base 1 and the solar panel 25. The outline shape of the sealing structure plate 14 is consistent with that of the solar panel 25 (or the solar panel protective shell), and its edge extends vertically upward to form a groove 13. The groove 13 is filled with phase change material (i.e., PCM material), and multiple heating wires are evenly laid inside the phase change material. Furthermore, the heating wires are electrically connected to the battery through a second power controller, thereby controlling the on and off of the heating wires through the second power controller. The sealing structure plate 14 serves to prevent the leakage of molten salt after the phase change material melts, prevent corrosion and damage to the circuit and electrical appliances, prevent short circuits in electrical appliances, and also prevent rainwater, gravel, small insects, etc. from entering the groove 13 and affecting the performance of the phase change material.

[0074] It should be noted that the PCM material can be formulated in various suitable ways. In this embodiment, it preferably contains 75% calcium chloride hexahydrate, 15% sodium chloride, and 10% glycerol by mass. This PCM material undergoes a phase transition at around 28°C. When the ambient temperature is higher than the phase transition temperature, the PCM material gradually melts and absorbs heat within a certain range. When the ambient temperature is lower than the phase transition temperature, the PCM material gradually solidifies. This heat absorption and release process is reversible, maintaining the temperature near the phase transition temperature. Furthermore, the heating wire is designed to be waterproof and corrosion-resistant. During installation, it can be evenly distributed within the PCM material. This allows for the activation of auxiliary heating to prevent the surface temperature of the table from becoming too low. It can also be activated periodically in winter to remove snow and frost from the surface of the table, preventing prolonged snow blockage of sunlight and shortening the power generation time of the solar panel 25, thus contributing to the stable operation of the solar panel 25.

[0075] Furthermore, the multi-functional outdoor ping-pong table of this application also includes a storage battery and a first power controller mounted on the base 1. The storage battery is electrically connected to the solar panel 3. At the same time, the storage battery is also electrically connected to the electrochromic glass 2 through the first power controller, so that the power supply to the electrochromic glass 2 can be controlled by the first power controller to achieve the color change of the electrochromic glass 2.

[0076] Furthermore, such as Figure 3 and Figure 5 As shown, between the bottom surface of the sealed structure plate 14 and the top surface of the base 1, there is also an energy storage battery cabinet 7 and four functional boxes with the same shape.

[0077] Specifically, the energy storage battery cabinet 7 is equipped with a cabinet door located in the longitudinal direction of the base 1 and can be opened and closed from the outside. The cabinet door can be unlocked and opened by the administrator using a key or fingerprint, which facilitates later maintenance, repair and replacement. The energy storage battery cabinet 7 is used to install batteries. In addition, the energy storage battery cabinet 7 is located in the center of the base 1, so that the two sides of the top of the base 1 form two independent areas.

[0078] Furthermore, the energy storage battery cabinet 7 can adopt various suitable structural layouts. In this embodiment, it is preferably divided into four sub-cabinets, each of which can house one battery. The four sub-cabinets are arranged side by side in pairs, and each of the four corners where the four sub-cabinets meet is provided with an opening groove as a wiring groove 17 for each sub-cabinet, so as to facilitate the wiring of the batteries in each sub-cabinet. In addition, each sub-cabinet is provided with a cabinet door to facilitate the replacement of positions, capacity selection, and battery replacement according to usage needs. Furthermore, the layout of the four sub-cabinets is beneficial for providing power to electrical appliances located in the four corners, and at the same time, it facilitates external equipment wiring, functional division, and later maintenance. In addition, a wiring groove 19 for circuit connection is reserved on the wall side of each sub-cabinet near the independent area.

[0079] Further, the four functional boxes are grouped in pairs and located in two independent areas respectively, and are evenly distributed at the four corners of the base 1. Further still, the four functional boxes are symmetrically distributed along the central axis plane where the table tennis net 15 is located; and each functional box is hermetically connected to the adjacent energy storage battery cabinet 7 in the lateral direction to facilitate the formation of corresponding air ducts subsequently; in addition, each functional box is provided with a door located in the longitudinal direction of the base 1 and capable of being opened and closed from the outside.

[0080] Similarly, the four functional boxes can adopt a variety of suitable layouts, and their uses can also be selected according to needs; in this embodiment, it is preferred that each functional box is divided into upper and lower sub-functional boxes, and each sub-functional box corresponds to a door; among the two functional boxes located on one diagonal of the base 1, the lower sub-functional box of each functional box serves as a storage box 11, and the upper sub-functional box serves as a socket power supply cabinet 12; inside the socket power supply cabinet 12, there are power output ports connected to the storage battery. There can be multiple power output ports, for example, it can include mobile device direct charging interfaces such as Type-C, USB-A, Lightning, Micro USB, etc. Further, 220V AC power interfaces and wireless charging areas can be added, etc., to provide power for the access of other electrical appliances and charge devices with wireless charging functions.

[0081] In addition, among the two functional boxes located on the other diagonal of the base 1, the lower sub-functional box of each functional box serves as a semiconductor thermostat box 5, and the upper sub-functional box serves as a towel temperature control cabinet 4, and the functional box containing the semiconductor thermostat box 5 and the towel temperature control cabinet 4 is located on the right side in the lateral direction of the base 1.

[0082] Further, both the towel temperature control cabinet 4 and the semiconductor thermostat box 5 use semiconductor thermoelectric cooling technology. Specifically, a plurality of thermocouple pairs are provided on at least one side of the semiconductor thermostat box 5 and the towel temperature control cabinet 4. Each thermocouple pair is a PN junction composed of a P-type semiconductor and an N-type semiconductor, and is connected to the storage battery through a third power controller. In addition, as Figure 10 shown, for each thermocouple pair, the P-type semiconductor or N-type semiconductor therein faces the inner cavity direction, and among the plurality of thermocouple pairs on each side, the number of P-type semiconductors facing the inner cavity direction is greater than the number of N-type semiconductors, and the P-type semiconductors are arranged in a "艹" shape, and the N-type semiconductors surround the P-type semiconductors.

[0083] The principle of the aforementioned semiconductor cooling and heating technology is as follows: When the user turns on the power through the third power controller, electrons start from the negative electrode, first passing through the P-type semiconductor and absorbing heat, and then releasing heat in the N-type semiconductor. Each time they pass through a PN junction, heat is transferred from one side to the other, creating a temperature difference and forming hot and cold ends. In addition, the hot and cold ends of the P-type and N-type semiconductors are arranged alternately, and they do not work simultaneously, but rather according to the user's needs. When the internal temperature is higher than the set temperature, the P-type semiconductor on the inside starts to work, absorbing heat and releasing heat from the N-type semiconductor on the outside, thus achieving cooling; conversely, the N-type semiconductor on the inside starts to work, absorbing heat from the outside and releasing internal heat, thus achieving heating.

[0084] It should be noted that the reason for using the above arrangement for multiple thermocouple pairs is that P-type semiconductors absorb heat from the surrounding environment, thus achieving a cooling effect, while N-type semiconductors release heat to the surrounding environment, thus achieving a heating effect. Since the heating efficiency of semiconductor cooling / heating elements is greater than their cooling efficiency (usually greater than 1), in order to balance the cooling and heating effects within a limited arrangement space and area, the number of P-type semiconductors facing inwards (i.e., towards the inner cavity) is greater than that of N-type semiconductors (see...). Figure 10 (See the diagram at the top). According to the second law of thermodynamics, where there is heat absorption, there must also be heat release. Therefore, P-type semiconductors and N-type semiconductors must exist in pairs, meaning that the number of N-type semiconductors facing outwards is greater than the number of P-type semiconductors (see...). Figure 10 (The figure at the bottom of the middle section) This arrangement is simple to set up and easy to install. It has been verified by numerical calculation and simulation of temperature physical field. It has good temperature regulation performance in both cooling and heating processes.

[0085] Furthermore, the aforementioned multiple thermocouple pair structure requires no refrigerant, allowing for continuous operation. It is pollution-free and environmentally friendly. The absence of rotating parts prevents rotational effects, unlike compressor-based refrigeration which can cause vibrations that might negatively impact the playing experience of table tennis enthusiasts. It operates quietly, has a long lifespan, is easy to install and replace, and boasts high heating efficiency. Although the power of a single element pair is small, combining them into a stack and using series / parallel connections of similar stacks to form a refrigeration system significantly increases power. The number of semiconductor refrigeration elements can be adjusted according to the climate temperature of the application environment, offering strong operability and adaptability. In addition, the thermocouple pair structure has very low thermal inertia, resulting in rapid cooling and heating. With good heat dissipation at the hot end and no load at the cold end, it only takes a short time after activation to reach the ideal temperature difference and produce a noticeable effect.

[0086] Furthermore, the purpose of the independently separated design of the semiconductor thermostat 5 and the towel temperature control cabinet 4 is that the internal temperature settings of the towel temperature control cabinet 4 and the semiconductor thermostat 5 are usually different. Generally, in the hot summer, table tennis enthusiasts require a lower temperature for the semiconductor thermostat 5 than for the towel temperature control cabinet 4, because sports sweat-absorbing towels do not need to be too low. Usually, a temperature slightly lower than the ambient temperature of 3-6°C is sufficient to provide athletes with a cool and comfortable wiping experience. Too low a temperature can easily cause athletes to catch a cold or cause other harm. On the other hand, the beverages refrigerated in the semiconductor thermostat 5 need to be at an even lower temperature to improve their taste. In the cold winter, table tennis enthusiasts also usually have different temperature requirements for the towel temperature control cabinet 4 and the semiconductor thermostat 5. The separate design can optimize the user experience of the present invention and also save energy to a certain extent, avoiding energy waste.

[0087] In addition, the towel temperature control cabinet 4 is installed on the upper part of the semiconductor constant temperature box 5, which makes it convenient for users to store and retrieve towels and conforms to the normal habits of most people. Furthermore, this embodiment includes two towel temperature control cabinets 4 and two semiconductor constant temperature boxes 5. The installation area is located on the right side of the player's usual standing position, which conforms to the habit of most table tennis players to take towels to wipe sweat.

[0088] Furthermore, in each functional box, the longitudinal width of the upper sub-functional box is preferably smaller than that of the lower sub-functional box, so that the cross-section of each functional box is L-shaped, and the sum of the heights of the upper and lower sub-functional boxes is equal to the height of the energy storage battery cabinet 7. In addition, it is preferable that there is a gap between two functional boxes located in the same independent area on the same side. This gap forms an exhaust duct 201 under the limitation of the bottom surface of the sealing structure plate 14 and the top surface of the base 1. The outlet of the exhaust duct 201 is located at the lateral end face of the base 1. At the same time, at the top of each functional box, a cavity is formed due to the difference in longitudinal width between its upper and lower sub-functional boxes. This cavity forms an air inlet duct 202 under the limitation of the bottom surface of the sealing structure plate 14. Moreover, the air inlet ducts 202 formed on both longitudinal sides in the same independent area are connected to the exhaust duct 201, so that one exhaust duct 201 and two air inlet ducts 202 in the same independent area form a whole in the shape of T. The heat dissipation air duct is of the type; furthermore, the inlet of the air inlet duct 202 is located at the horizontal end face of the base 1, and the outlet of the air inlet duct 202 serves as the inlet of the exhaust duct 201.

[0089] Accordingly, the multi-functional ping-pong table of this application also includes an intake fan 231, an exhaust fan 232, a metal dustproof net 21, and a wind deflector 22.

[0090] The intake fan 231 is installed inside the intake duct 202, and its outlet faces the exhaust duct 201; the exhaust fan 232 is installed inside the exhaust duct 201, and its outlet faces the outer side of the base 1. In addition, both the intake fan 231 and the exhaust fan 232 are connected to the battery through a fourth power controller to control the power supply to the intake fan 231 and the exhaust fan 232.

[0091] Multiple metal dust screens 21 are provided, preferably made of 304 stainless steel with a mesh size of 400. They are respectively installed at the inlet of the air inlet duct 202 and the outlet of the air outlet 201 to prevent insects, leaves and other impurities from entering the T-shaped heat dissipation air duct and effectively reduce the dust and grit inside. In addition, the air outlet of the exhaust fan 232 is directly opposite the metal dust screen 21 at the same location.

[0092] The wind deflector 22, made of metal or acrylic material, is installed at the outlet of the exhaust duct 201 and is located on top of the metal dustproof mesh 21 at the outlet. It forms a semi-enclosed space with the exhaust duct 201 to guide airflow (see [reference needed] for specific airflow direction). Figure 9 (As indicated by the middle arrow), while also preventing the exhaust fan 232 from blowing directly on the operator.

[0093] Furthermore, both the intake fan 231 and the exhaust fan 232 are preferably linear fans. The number of fans and the total power of the exhaust fan 232 are greater than (for example, 1.5 to 1.8 times) the number of intake fans 231 installed on both sides. Preferably, the exhaust fan 232 has a predetermined tilt angle with the horizontal direction. Preferably, the predetermined tilt angle is 13.5°. In conjunction with the baffle plate 22, it can promote natural convection near the table, making the player feel cool and comfortable, while not significantly affecting the trajectory of the table tennis ball, and helping to dissipate heat from the heat-generating equipment or components inside the table.

[0094] Understandably, since the location of the switch (i.e., the power controller) and the wiring layout are relatively mature technologies, and appropriate choices can be made according to needs, they will not be elaborated here.

[0095] Furthermore, a battery connection box 18 is provided on the surface of the sealed structure plate 14 for transmitting the electrical energy generated by the solar panel 25 to the storage battery; and a load-bearing frustum 16 is evenly provided at the four corners of the top of the sealed structure plate 14 for supporting the solar panel 25 located on its top; and a through hole is provided at the center of the sealed structure plate 14 corresponding to the wiring groove 17, and a seepage-proof shielding plate is vertically provided around the through hole. The height of the seepage-proof shielding plate is at least greater than the height of the phase change material layer after it is completely heated, melted and expanded, thereby effectively preventing the melted phase change material from seeping out and avoiding impurities from entering the phase change material and causing oxidation or other chemical reactions with the heating wire layer (i.e., the groove 13).

[0096] Furthermore, to ensure the stability of the overall structure, such as Figure 6 As shown, below the base 1, from top to bottom, there are structural steel plates 10 with consistent outer contours, rubber shock-absorbing pads 9, and a bottom load-bearing shell 8. The installation area of ​​the structural steel plate 10 is located below the semiconductor constant temperature box 5, the energy storage battery cabinet 7, and the storage box 11. Preferably, the area of ​​the structural steel plate 10 is greater than or equal to the total area of ​​the adjacent structures above, which can avoid damage to sharp corners and improve the overall aesthetics. The rubber shock-absorbing pads 9 are made of hard vulcanized rubber, which has good properties such as shock absorption, sun resistance, anti-slip, high elasticity, and wear resistance. Together with the structural steel plate 10, they can achieve stable support and long service life for the table tennis table.

[0097] Finally, as Figure 4 and Figure 8 As shown, the bottom load-bearing shell 8 has two load-bearing bases 6 along its width or length, and at least one structural reinforcing beam 24 connecting the two load-bearing bases 6 to stabilize the overall structure. Specifically, in this embodiment, the bottom corners of the load-bearing bases 6 preferably have rounded surfaces with a certain thickness, and the material used is an alloy material with high static and dynamic stiffness, good vibration resistance, good thermal stability and corrosion resistance, and good safety protection performance. The number of structural reinforcing beams 24 is two and they are vertically fixedly connected to the load-bearing bases 6.

[0098] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
