[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] One of the core concepts of the embodiments of the present invention is that those preset frequency signals that may interfere with the target wireless signals received and processed by the external antenna can be blocked in a targeted manner through the radiating array, thereby avoiding the influence of spatial radiation on the sensitivity of the external antenna reception; the present invention only needs to set up the radiating array, which can save the cost of the number of components in space and reduce the mainboard stacking space; the present invention couples and blocks the influence of the wireless signals of the corresponding frequency on the antenna reception sensitivity, thereby solving the problem of decreased antenna sensitivity, improving the antenna communication strength of the vending cabinet product, improving the stability and reliability of the screen display component of the vending cabinet, and ensuring the normal presentation of the display content is not interfered by external clutter.

[0028] Reference Figure 1 , showing a structural block diagram of a vending cabinet 10 provided by the present invention, the vending cabinet may include

[0029] Cabinet 101,

[0030] In the embodiment of the present invention, the cabinet body 101 is the basic frame structure of the entire vending cabinet, which plays the role of accommodating and supporting other components. It defines the appearance and internal space of the vending cabinet, provides a physical carrier for activities such as selling related commodities, and also provides a basic guarantee for the installation and stable operation of other components.

[0031] A screen display component 102 is disposed in the cabinet and is used to obtain wireless signals and display corresponding content according to the wireless signals;

[0032] In the embodiment of the present invention, the screen display component 102 is arranged in the cabinet and is connected to the external antenna 103 through the antenna harness 105. It can perform effective signal transmission interaction with the external antenna and work together to realize related functions.

[0033] The screen display component has the ability to obtain wireless signals and can display corresponding content based on the received wireless signals. For example, it may receive wireless signals such as product information, promotional information, and operation guidance prompts pushed from the background server, and then display this information on the screen in the form of intuitive graphics and texts, etc., to facilitate customers to understand the situation of the goods in the vending machine and make corresponding operation choices, greatly improving the interactivity of the vending machine and the efficiency of information transmission.

[0034] The external antenna 103 is connected to the screen display component via an antenna harness, and the external antenna is used to receive wireless signals and transmit the wireless signals to the screen display component.

[0035] In the embodiment of the present invention, the external antenna 103 is connected to the screen display component 102 through an antenna harness, and is the front-end component of the entire wireless signal receiving link. It is mainly responsible for receiving external wireless signals, such as related signals from surrounding network base stations or specific wireless transmitting devices, and then transmitting the received wireless signals to the screen display component 102, which is equivalent to building an external "bridge" for the screen display component to obtain information, thereby ensuring the smooth implementation of subsequent information display functions.

[0036] The antenna harness plays a key role in transmitting wireless signals in the vending machine. From a physical perspective, wireless signals are essentially electromagnetic waves. When the external antenna 103 receives a wireless signal, an induced current is generated in the conductor of the antenna. This induced current carries the information of the wireless signal and is transmitted through the antenna harness.

[0037] The antenna harness is usually composed of metal wires. The free electrons in the metal wires can move in a directed manner under the action of the electric field. When the induced current generated by the external antenna enters the antenna harness, the electrons will flow along the wire from the antenna end to the screen display component 102 end. This flow of electrons is equivalent to signal transmission, and it is carried out in accordance with the basic laws of electromagnetism.

[0038] During the transmission process, the connection part between the antenna harness and the radiation array 104 involves the electromagnetic coupling phenomenon. When the current carrying the wireless signal passes through the antenna harness, a magnetic field will be generated around the radiation array due to the connection between the radiation array 104 and the antenna harness. According to the law of electromagnetic induction, the changing magnetic field will generate an induced electromotive force in the radiation array.

[0039] For normal signal transmission frequencies, the radiating array will not cause excessive interference to the signal. However, when a wireless signal of a preset frequency appears, the special design of the radiating array will cause it to produce strong electromagnetic induction to the signal of the preset frequency, thereby blocking these signals and preventing them from continuing to be transmitted in the antenna harness.

[0040] After the antenna harness transmits the wireless signal to the screen display component 102, there is a special signal processing circuit inside the screen display component. These circuits usually include amplifiers, filters and other components. The amplifier can enhance the strength of the signal. Because the signal may be attenuated to a certain extent during the transmission process, the filter is used to further filter the signal and remove some clutter that may be mixed in during the transmission process, leaving only useful wireless signal components. Then, the processed signal is converted into an electrical signal format that can be recognized by the screen display component, so as to display the corresponding content according to the wireless signal. For example, the signal is converted into an electrical signal that controls the lighting and extinguishing of pixels to display text, pictures or videos.

[0041] The radiation array 104 is connected to the antenna harness and is used to block wireless signals of a preset frequency.

[0042] In the embodiment of the present invention, the radiating array 104 is also connected to the antenna harness and is in a related link of the entire wireless signal transmission link. Its key function is to block wireless signals of preset frequencies. In actual application scenarios, there may be various wireless signals in the surrounding environment, some of which have specific frequencies and may interfere with the wireless signals received and processed by the vending machine itself. The radiating array 104 can specifically block these interfering wireless signals of preset frequencies, thereby ensuring the accuracy and stability of the wireless signals received by the external antenna and transmitted to the screen display component, which helps to more reliably implement the relevant functions of the vending machine.

[0043] In one embodiment of the present invention, the vending cabinet may further include a pickup cabinet 106 . After the user has paid, the vending cabinet may deliver the goods to the pickup cabinet 106 , where the user may pick up the goods.

[0044] The present invention discloses a vending cabinet, which can specifically block preset frequency signals that may interfere with target wireless signals received and processed by an external antenna through a radiating array, thereby avoiding the influence of space radiation on the sensitivity of the external antenna receiving. The present invention only needs to set up a radiating array, which can save the cost of the number of components in space and reduce the mainboard stacking space. The present invention blocks the influence of wireless signals of corresponding frequencies on the antenna receiving sensitivity through coupling, thereby solving the problem of reduced antenna sensitivity, improving the antenna communication strength of the vending cabinet product, improving the stability and reliability of the screen display component of the vending cabinet, and ensuring the normal presentation of the display content without being interfered by external clutter.

[0045] In an embodiment of the present invention, the radiation array includes a plurality of radiation arrays, the plurality of radiation arrays are respectively connected to the antenna harness, and each of the plurality of radiation arrays is respectively used to block wireless signals of different frequencies.

[0046] In an embodiment of the present invention, when the vending cabinet adopts a design in which multiple radiating arrays are respectively connected to the antenna harness, this structure can provide more sophisticated signal interference protection. Each radiating array can block wireless signals of a specific frequency. This is like setting up multiple different "checkpoints" on the "channel" for wireless signal transmission, and each "checkpoint" (radiating array) is specifically responsible for intercepting "bad signals" of a specific frequency.

[0047] Compared with using only one radiating array, the combination of multiple radiating arrays can cover a wider frequency range. For example, in a complex commercial environment, there may be multiple interference sources at the same time, and the interference signals they emit have different frequencies. By setting up multiple radiating arrays, the vending machine can more effectively deal with such complex interference situations.

[0048] The physical structure and material properties of each radiation array determine its resonant frequency. When the frequency of the wireless signal is close to the resonant frequency of the radiation array, the radiation array will produce a strong electromagnetic response to the signal. This response can be to absorb signal energy or change the direction of signal propagation, thereby blocking wireless signals of specific frequencies.

[0049] In actual scenarios, such as in a large shopping mall, there may be devices using Bluetooth technology (usually operating in the 2.4GHz frequency band), Wi-Fi routers (may operate in the 2.4GHz or 5GHz frequency bands), and some devices using radio frequency identification (RFID) technology (operating at various frequencies such as low frequency, high frequency, and ultra-high frequency) around the vending cabinets. These devices with different frequencies may interfere with the wireless signal transmission of the vending cabinets. By setting up multiple radiation arrays, one of them can block the Bluetooth signal frequency, another can block the Wi-Fi signal frequency that may interfere, and another can block the RFID signal frequency, thereby ensuring the accuracy and stability of the wireless signal transmission of the vending cabinet.

[0050] Multiple radiating arrays work closely with the external antenna and antenna harness. The external antenna is responsible for receiving all wireless signals including interference signals, and the antenna harness transmits these signals. During the transmission process, multiple radiating arrays filter and block interference signals of different frequencies according to their own characteristics. Then, the "purified" wireless signal is transmitted to the screen display component through the antenna harness. This collaborative working mechanism enables the vending cabinet to effectively receive and utilize the required wireless signals in a complex electromagnetic environment, thereby ensuring the normal operation of its functions such as displaying product information and receiving remote control commands.

[0051] In one embodiment of the present invention, the plurality of radiation arrays include a first radiation array and a second radiation array; the first radiation array is used to block wireless signals of a first frequency; and the second radiation array is used to block wireless signals of a second frequency.

[0052] In an embodiment of the present invention, the first radiating array may be designed to block wireless signals of a first frequency. This first frequency is usually determined based on the most common signal frequency in the environment in which the vending machine is located and which has the greatest interference with its own signal transmission. For example, if there is a large number of Bluetooth devices using a specific frequency band around the vending machine, and this frequency band is set to the first frequency, the first radiating array may be optimized for this Bluetooth frequency band, and its physical structure and material selection will cause it to resonate at this first frequency, thereby effectively absorbing or reflecting signals of this frequency and reducing its interference with wireless signals transmitted by the antenna harness.

[0053] The second radiation array and the second frequency signal: Similarly, the second radiation array is used to block the wireless signal of the second frequency, which can be the frequency of another common interference source, such as a frequency band commonly used by surrounding Wi-Fi devices. Its working principle is similar to that of the first radiation array. It is also based on its own physical and material properties to produce specific electromagnetic induction for the second frequency signal to achieve the purpose of blocking the frequency signal. These two radiation arrays are designed for different frequencies respectively, which can more accurately respond to multiple interference sources and improve the anti-interference ability of the vending cabinet in complex electromagnetic environments.

[0054] In an environment where both first-frequency and second-frequency interference signals exist, the first radiation array and the second radiation array work together. They can filter out two interference signals of different frequencies during the transmission of the antenna harness, respectively, so that the wireless signal finally transmitted to the screen display component is purer. For example, in the food court area of ​​a shopping mall, there may be interference from both Bluetooth devices used by customers and Wi-Fi devices of nearby businesses around the vending machine. Through the protection of these two radiation arrays, the quality of receiving and processing wireless signals of the vending machine can be significantly improved.

[0055] This dual-frequency protection helps to enhance the stability of the overall system of the vending cabinet and reduces the impact of the two main interference frequencies on signal transmission. After receiving a stable wireless signal, the screen display component can more reliably display product information, promotional activities and other content. At the same time, other wireless communication functions that the vending cabinet may have, such as remote monitoring or software updates, can also be carried out more smoothly due to the stable signal transmission, reducing the risk of system failure or information errors due to signal interference.

[0056] In actual applications, the settings of the first frequency and the second frequency can be flexibly adjusted according to the specific use environment of the vending cabinet. If the vending cabinet is moved to a new location and the frequency of the surrounding interference sources changes, the first radiation array and the second radiation array can adapt to the new interference frequency by changing their physical dimensions or replacing some materials. This flexibility enables the vending cabinet to better adapt to different electromagnetic environments and extend the effective use period of the equipment.

[0057] Moreover, the combination of the first radiation array and the second radiation array can also be optimized as needed. For example, in some environments, it may be necessary to further strengthen the blocking of the first frequency signal. By adjusting the positions of the two radiation arrays or changing their size ratio, the blocking effect of the first radiation array on the first frequency signal can be more significant.

[0058] In an example, the first radiation array is used to block wireless signals that affect Band 5 wireless signals, and the second radiation array is used to block wireless signals that affect Band 8 wireless signals.

[0059] In one embodiment of the present invention, the wavelength of the first radiation array is 1 / 4 of the wavelength corresponding to the wireless signal of the first frequency.

[0060] In an embodiment of the present invention, the first frequency corresponds to the frequency of Band 5, which is f1=850 Hz. The corresponding wavelength can be calculated according to λ1=V / f1, where V corresponds to the speed of light, and λ1 is the wavelength corresponding to the wireless signal of the first frequency. Therefore, the wavelength of the first radiation array is 1 / 4λ1.

[0061] In one embodiment of the present invention, the wavelength of the second radiation array is 1 / 4 of the wavelength corresponding to the wireless signal of the second frequency.

[0062] In an embodiment of the present invention, the second frequency corresponds to the frequency of Band 8, which is f2=900 Hz. The corresponding wavelength can be calculated according to λ2=V / f2, where V corresponds to the speed of light, and λ2 is the wavelength corresponding to the wireless signal of the second frequency. Therefore, the wavelength of the second radiation array is 1 / 4λ2.

[0063] like Figure 2 , shows a schematic diagram of an external antenna provided by an embodiment of the present invention. It can be seen that the radiating array 104 may include a first radiating array 1041 and a second radiating array 1042, wherein the first radiating array 1041 can be used to block wireless signals that affect Band 5 band wireless signals, and the second radiating array 1042 is used to block wireless signals that affect Band 8 band wireless signals.

[0064] In an embodiment of the present invention, the distance between the first radiation array and the second radiation array is 3 mm.

[0065] In the embodiment of the present invention, in order to avoid mutual interference of electromagnetic fields caused by wavelength differences between the two radiation arrays in the process of blocking signals, as shown in FIG. Figure 2 The distance between the first radiation array 1041 and the second radiation array 1042 can be set to 3 mm. The distance of 3 mm can make the electromagnetic fields of the first radiation array and the second radiation array relatively independent in space, thereby ensuring that they can independently block signals of corresponding frequencies.

[0066] In an embodiment of the present invention, the distance between the radiating element and the external antenna is greater than a first preset distance and less than a second preset distance.

[0067] In an embodiment of the present invention, the first preset distance may be 2.5 cm, the second preset distance may be 3.5 cm, and the distance between the radiating array and the external antenna body may be within a range of 2.5 cm to 3.5 cm. The radiating array can be in a suitable position to effectively perform its function. If the distance is too close, the electromagnetic coupling between the radiating array and the antenna body may be too strong, affecting the normal reception and transmission of signals by the antenna body. If the distance is too far, the blocking effect of the radiating array on the interference signal of the preset frequency may be greatly reduced. In the limited internal space of the vending machine, the distance of 2.5 cm to 3.5 cm can ensure the function of the radiating array while leaving enough space for other components. Moreover, this distance range is also convenient for installation and maintenance. When installing or replacing the radiating array, technicians can operate within this relatively flexible distance range to achieve the best system performance.

[0068] In one embodiment of the present invention, the vending cabinet further includes a control component, which is used to obtain status information of the vending cabinet and send the status information of the vending cabinet to the terminal device via an external antenna.

[0069] In the embodiment of the present invention, Figure 3 , showing a structural block diagram of another vending cabinet 10 provided by an embodiment of the present invention, the vending cabinet also includes a control component 108, and the control component 108 can collect various status information of the vending cabinet in real time. The status information covers multiple aspects, such as the temperature inside the vending cabinet, which is very important for storing some commodities with temperature requirements. By detecting and transmitting data to the control component through the temperature sensor, it can be known whether the internal environment of the vending cabinet is suitable; it also includes the inventory information of the commodities, and the number of remaining commodities can be counted with the help of the internal cargo identification device. In addition, information such as the opening and closing status of the cabinet door and whether the operation of the equipment is normal can also be obtained by the control component.

[0070] After obtaining the status information, the control component 108 can send the status information of these vending cabinets to the terminal device through the external antenna 103. This function realizes the information exchange between the vending cabinet and the external terminal device, so that relevant personnel can remotely monitor the real-time status of the vending cabinet. For example, even if the operating personnel are not at the vending cabinet, they can use the terminal device to promptly understand whether the goods in a certain vending cabinet are about to be sold out, so as to arrange for replenishment; or when they know that the temperature of the vending cabinet is abnormal, they can promptly arrange maintenance personnel to check and handle it, which greatly improves the efficiency and convenience of the operation and management of the vending cabinet.

[0071] As an important component for receiving and sending wireless signals, the external antenna is closely connected to the control component. The control component converts the sorted vending machine status information into a signal format suitable for wireless transmission and transmits it to the external antenna. After receiving these signals, the external antenna transmits them to the surrounding space in the form of electromagnetic waves so that the terminal device can receive them. In addition, the external antenna has certain signal gain and directionality, which can ensure that the signal is transmitted with a strong intensity in the general direction of the target terminal device, thereby ensuring the effectiveness of information transmission.

[0072] The terminal device is at the receiving end. It needs to have a corresponding wireless communication module and supporting software applications to process the received status information of the vending cabinet. For example, the software on the terminal device must be able to parse the received signal, restore it to specific status information such as temperature value and inventory quantity, and display it to the management personnel in an intuitive form. At the same time, the terminal device can also send instructions to the control component of the vending cabinet. After receiving these instructions through the external antenna, the control component will perform the corresponding operations to realize two-way information interaction and remote control functions.

[0073] Through the coordinated work of control components, external antennas and terminal devices, the operation and management of vending cabinets becomes more efficient. Merchants can reduce the frequency of manual on-site inspections and reduce labor costs. At the same time, they can grasp the situation of each vending cabinet more timely and accurately, and quickly respond to needs such as replenishment and maintenance, ensuring that the vending cabinet is always in good operating condition, thereby improving product sales opportunities and customer satisfaction.

[0074] In one embodiment of the present invention, the status information includes operation information, and the control component is further configured to output an alarm message when the operation information is abnormal.

[0075] In an embodiment of the present invention, the operating information of the vending cabinet includes multiple key parts, which may include the power system information of the equipment, such as whether the power supply is normal, whether the battery power is sufficient, etc., and also include the operating parameters of the refrigeration or heating system, such as the working status of the compressor, whether the temperature control system is operating normally, this information is crucial for maintaining a suitable storage temperature of goods in the vending cabinet. In addition, the operation status of the payment system of the vending cabinet is also within the scope of the operating information, including whether the payment module communicates normally, whether it can accurately identify payment instructions, etc.

[0076] These operating information can fully reflect the working status of the vending cabinet. By monitoring this information, it is like giving the vending cabinet a comprehensive "physical examination" and timely discovering potential problems. For example, timely understanding of power system information can prevent the deterioration of goods due to power outages; and monitoring of the temperature control system can ensure that the goods in the vending cabinet are always in the best storage environment, extend the shelf life of the goods, and increase the possibility of customers purchasing. Monitoring the payment system can ensure the smooth progress of transactions and avoid payment failures that affect sales.

[0077] A series of judgment criteria are pre-set inside the control component to determine whether the operating information is abnormal. For the power system, if the voltage is monitored to be out of the normal range or the power supply is frequently interrupted, it will be judged as an abnormality of the power system. For the temperature control system, when the difference between the actual operating temperature of the refrigeration or heating equipment and the set temperature exceeds a certain threshold or the equipment cannot reach the set temperature for a long time, it is considered abnormal. For the payment system, if there are multiple consecutive payment failures or it is impossible to communicate normally with the payment server, it will also be judged as abnormal.

[0078] Once it is determined that the operating information is abnormal, the control component will output alarm information in a variety of ways. A common way is to pop up a striking alarm prompt box on the screen display component of the vending machine itself, displaying the specific abnormal content, such as "Temperature adjustment system failure, please repair in time". At the same time, the control component will also send the alarm information to the terminal device through an external antenna. After the terminal device receives the alarm information, it can remind the management personnel through sound vibration or highlighting the alarm content on the screen with special colors and icons. This ensures that whether on-site or remote, relevant personnel can be informed of abnormal conditions in the vending machine at the first time and take timely measures to deal with them.

[0079] In one embodiment of the present invention, the screen display component also includes a scanning component, which is used to obtain product information selected by a user, identify corresponding barcode information based on the product information, determine location information of the product corresponding to the product information based on the barcode information, and send the location information to the control component, which is used to transport the product to the output port based on the location information.

[0080] In the embodiment of the present invention, Figure 3 The screen display component also includes a scanning component 1021. As a part of the screen display component, the scanning component 1021 plays a key role in the operation of the vending machine. When the user selects the product he wants to buy on the screen, the scanning component will start the corresponding scanning function to obtain the product information. It scans the barcode on the product through optical scanning and other technologies, and reads the coded information contained in the barcode. The barcode contains rich product-related data, such as the product number, category, specifications and other key content. The scanning component relies on the built-in recognition algorithm to accurately parse the corresponding product details based on the read barcode information, and then determine which specific product is selected by the user.

[0081] After identifying the barcode information corresponding to the product, the scanning component will further determine the location information of the product in the vending cabinet based on the information. The interior of the vending cabinet usually has a specific layout and storage location number, and each product is placed in the corresponding area. The scanning component can quickly and accurately find the specific location of the product, such as which layer or column it is on, by associating with the vending cabinet storage system. Then, the scanning component will send this location information to the control component to prepare for the subsequent delivery of the product.

[0082] After receiving the product location information sent by the scanning component, the control component will issue precise operating instructions to the relevant mechanical devices responsible for transporting the products in the vending machine based on its own control logic and algorithm. For example, if the product is located on an upper level inside the vending machine, the control component will first control the corresponding lifting device to move to that level, and then command the conveyor belt or robotic arm to grab the product and move it to the designated output port. It is like the "brain" of the entire product transportation process, coordinating the orderly operation of various transportation components to ensure that the products can be accurately and efficiently transported to the output port for user retrieval.

[0083] In one embodiment of the present invention, the vending cabinet includes a sensor, which is used to detect commodities at various positions in the vending cabinet. When the commodity information at the target position in the vending cabinet is sold out, a restocking reminder message is issued.

[0084] In the embodiment of the present invention, Figure 3The vending cabinet also includes a sensor 109, which is connected to the screen display component 102. The sensors equipped in the vending cabinet can be of various types, and common ones include photoelectric sensors, weight sensors, and infrared sensors. The photoelectric sensor uses the propagation and reflection principles of light to detect the presence of goods. When the light is blocked by the goods or the reflection situation changes, it can be determined that there are goods placed at the corresponding position. The weight sensor determines whether there are goods by sensing the weight of the object placed above it. Different weights of goods will cause the sensor to produce different electrical signal changes, thereby identifying the status of the goods. The infrared sensor relies on the induction of infrared rays on objects. When there are goods in its detection range, the reflection of infrared rays and other conditions change, thereby detecting the presence of goods.

[0085] These sensors are reasonably distributed in various positions of the vending cabinet, so that they can achieve comprehensive detection of goods in different areas and on different shelves in the vending cabinet. For example, corresponding sensors can be installed in different grids of each shelf. No matter whether the goods are beverage bottles, snack bags or other forms, they can be accurately sensed to determine whether they exist in the corresponding positions. In this way, the situation of goods in various positions in the vending cabinet can be grasped in real time, and a relatively complete product inventory monitoring system can be built.

[0086] When the sensor detects that the product information at the target location in the vending cabinet is sold out, that is, when the sensor at the corresponding position can no longer detect the existence of the product, it will trigger the issuance of a restocking reminder message. This process is based on the information interaction between the sensor and the control component of the vending cabinet. The sensor converts the detected missing goods into an electrical signal and transmits it to the control component. The control component then determines whether the conditions for issuing a restocking reminder message are met based on the preset program logic. Once the conditions are met, the corresponding reminder operation is initiated.

[0087] Replenishment reminder information can be presented in a variety of ways. A common method is to pop up a striking prompt box on the screen display component of the sales cabinet, displaying text content such as "A certain product is sold out, please replenish it in time", so that on-site staff can intuitively see the information of the products that need to be replenished; at the same time, the control component can also send the reminder information to the terminal device through an external antenna, such as sending it to the manager's mobile phone management application, and remind the manager to arrange replenishment in time through sound, vibration or message push. In this way, even if the manager is not at the sales cabinet, he can know the replenishment needs at the first time, ensure sufficient supply of products in the sales cabinet, and avoid affecting sales efficiency and customer satisfaction due to out-of-stock products.

[0088] In one embodiment of the present invention, the vending cabinet further includes a radio frequency coaxial connector, which is disposed on the screen display assembly; the antenna harness is connected to the screen display assembly via the radio frequency coaxial connector.

[0089] In the embodiment of the present invention, Figure 2 The vending cabinet may also include an RF coaxial connector SMA, which is arranged on the screen display component; the antenna harness is connected to the screen display component through the RF coaxial connector. In the application scenario of the vending cabinet, the RF coaxial connector SMA is arranged on the screen display component, which builds a reliable connection bridge between the antenna harness and the screen display component. Since wireless signals are often in a higher frequency range, a connection method that can adapt to high-frequency transmission and has stable performance is required. It can accurately transmit the wireless signal received and transmitted by the antenna harness to the screen display component, ensuring the integrity and accuracy of the signal when entering the screen display component, so that the screen display component can normally display the corresponding content according to the received wireless signal. The display of content such as product information and promotional activities depends on this stable signal transmission link.

[0090] The present invention discloses a vending cabinet, which can specifically block preset frequency signals that may interfere with target wireless signals received and processed by an external antenna through a radiating array, thereby avoiding the influence of spatial radiation on the receiving sensitivity of the external antenna; the present invention only needs to set up a radiating array, which can save the number and cost of components in space and reduce the stacking space of the mainboard; the present invention blocks the influence of wireless signals of corresponding frequencies on the receiving sensitivity of the antenna through coupling, thereby solving the problem of reduced antenna sensitivity, improving the antenna communication strength of the vending cabinet product, improving the working stability and reliability of the screen display component of the vending cabinet, and ensuring the normal presentation of the display content without being interfered by external clutter.
