[0002] In the production and sale process of range hood, brand range hood is loved by the majority of users due to its high quality, good reputation and brand influence, so that its commercial value is much higher than ordinary similar range hood. Under the temptation of high profit, by the phenomenon of different prices due to different economic levels in each region, different consumer habits, different product sales, goods are dumped to non-jurisdiction, non-target market, called serial goods, serial goods and low-price sales are often linked together, leading to market price chaos, and the normal sales price of dealers is seriously affected. In order to maintain their own sales network, dealers often have to sell at a loss, no profit or at a loss, which undermines the sales enthusiasm of dealers, and dealers lose confidence in the brand and even refuse to sell products, which damages the brand image of the enterprise products and the profits of the manufacturer. Therefore, the behavior of serial goods not only destroys the normal sales channel and sales network of products, but also affects the reputation and profits of brand products, and the interests of consumers cannot be protected.
[0003] In order to effectively prevent the occurrence of serial goods, range hood manufacturers have established a series of prevention mechanisms from the source of product production, for example, a production machine code reading and writing interface is usually reserved on the power board, and then during production, the production machine code is written into the power board through a special coding tool. When the product goes to market, when it is necessary to query whether it is serial goods, the salesperson disassembles the power box and reads the production machine code through a special reading tool connected to the machine code reading interface on the power board. This method needs to reserve a special machine code reading and writing interface on the power board, which requires additional raw material cost and production cost of the power board. In addition, when reading the machine code, the power box of the whole machine needs to be disassembled to read the machine code, which is very inconvenient to operate. UTILITY MODEL CONTENTS

[0024] A kind of anti-serial goods range hood, please refer to Figures 1-3 As shown, it includes a range hood, the range hood is provided with a switch module 100, the switch module 100 is provided or connected with an electronic board, and the electronic board is provided with a first control unit 110;The first infrared receiver head 120, the first infrared emitter tube 130, the display unit 140 and the key unit 150 are provided on the switch module 100, the first infrared receiver head 120, the first infrared emitter tube 130 can be used for model code infrared signal writing and reading, and the model code infrared signal corresponds to model code / electronic barcode, which can provide information to identify the batch, origin and other effective information of the range hood, to prevent serial goods;The range hood is matched with a model code reading and writing tool, and the electronic board is provided in the model code reading and writing tool 200, and the second control unit 210 is also provided on the electronic board, and the model code reading and writing tool 200 is also provided with the second infrared receiver head 220 and the second infrared emitter tube 230 matched with the first infrared receiver head 120 and the first infrared emitter tube 130 of the switch module 100, and the model code infrared signal transmission between the range hood and the model code reading and writing tool 200 can be realized through the cooperation of the first infrared receiver head 120, the first infrared emitter tube 130, the second infrared receiver head 220 and the second infrared emitter tube 230, and the model code infrared signal writing and reading of the switch module 100 is carried out through the model code reading and writing tool 200 when the range hood is produced or sold, the reading and writing process is convenient, and the range hood can be completed without disassembling, reducing the production cost of model code reading and writing.
[0025] The model code reading and writing tool 200 can be an infrared gun with infrared emission and infrared receiving functions, or a remote controller with infrared emission and infrared receiving functions.
[0026] Further, the first infrared receiving head 120 and the second infrared receiving head 220 are used to receive the model code infrared signals, and the first infrared emission tube 130 and the second infrared emission tube 230 are used to emit the model code infrared signals. In this embodiment, the first infrared receiving head 120 and the second infrared receiving head 220 and the first infrared emission tube 130 and the second infrared emission tube 230 on the model code reading and writing tool 200 and the switch module 100 are of the same specification and can realize infrared signal transmission. Alternatively, different specifications can be used in other embodiments, as long as normal infrared signal transmission can be realized.
[0027] The first infrared receiving head 120 and the first infrared emission tube 130 on the range hood are in close proximity to each other and are connected by a connecting line. The close proximity of the two facilitates the pairing and reading and writing of the range hood and the model code reading and writing tool 200, so that the model code infrared signals can be smoothly received and emitted. During the reading and writing process, the model code reading and writing tool 200 only needs to be aligned with the same position of the switch module 100, so as to prevent poor reception or transmission of the model code infrared signals.
[0028] More specifically, the first infrared receiving head 120 and the first infrared emission tube 130 are arranged on the range hood switch module 100. The first infrared receiving head 120 can receive the infrared signals emitted by the second infrared emission tube 230 on the model code reading and writing tool 200. For example, if the model code of the range hood switch module 100 is 1340, the wavelength emitted by each number in this group of numbers is different. For example, the wavelength of 1 is A1, the wavelength of 3 is A3, and so on. Then, the first infrared emission tube 130 sequentially emits infrared rays with wavelengths A1, A3, A4, and A0. After the reading and writing tool receives the infrared signals, the electronic board of the model code reading and writing tool 200 identifies the model code.
[0029] Similarly, in the reverse direction, if the range hood switch module 100 does not have a written model code, the second infrared emission tube 230 of the model code reading and writing tool 200 emits infrared signals with wavelengths A1, A3, A4, and A0. Then, the first infrared receiving head 120 of the range hood switch module 100 receives the infrared signals and transmits them to the electronic board. The electronic board automatically saves the model code 1340. In this way, the reading and writing of the model code is completed.
[0030] In addition, the signal transmission between the infrared receiving and the infrared emission is known to those skilled in the art.
[0031] Further, the key unit 150 is a touch key or a mechanical key; the key unit 150 has keys for controlling the switch of the range hood and / or keys for adjusting the functions and / or keys for switching the model code reading and writing program.
[0032] The switch, the function adjustment, the model code writing program and the model code reading program of the range hood can be controlled by the key unit 150, so that the user can normally operate and use the range hood, and the reading and writing of the model code during the production or sales process can also be switched by the key unit 150, without the need for additional hardware;
[0033] The reading and writing program can be directly controlled by the set reading and writing keys, or can be entered by pressing / touching a key multiple times, or can be entered by simultaneously pressing / touching multiple keys, and can be preferably entered by simultaneously pressing / touching multiple keys, and the specific key combination and the operation of long pressing can prevent the user from switching the program by mistake when using the range hood, wherein the reading and writing program includes the writing program and the reading program;
[0034] The display unit 140 is a liquid crystal display screen, and the display unit 140 can display the general use interface of the range hood and the specific display interface when reading and writing the model code; when the user uses the range hood, the display screen displays the general use interface, and the general use interface displays the parameters such as the wind speed and the wind volume to provide the user with use information, and the specific display interface can be entered by key switching, and the specific display interface can display the specific information or the state of the model code infrared signal, so as to enable the production personnel to judge whether the range hood has entered the state of being readable and writable for the model code; the model code reading and writing tool 200 is provided with the specific information or the state of the model code infrared signal that can be displayed, and the model code reading and writing tool 200 displays the model code through the display unit 140 after receiving the model code infrared signal sent by the switch module 100; when the manufacturer produces the range hood in batches, the model code reading and writing tool 200 can match multiple range hoods to read and write the model code, so as to facilitate the reading and writing of the model code during the production, and to realize that one model code reading and writing tool 200 reads and writes the model code of a large number of range hoods.
[0035] Further, as Figure 1As shown, the process of the range hood writing the model code is as follows: when the range hood is produced, the switch module 100 has been installed, the model code writing program is entered by combining long press key unit 150, the liquid crystal display screen on the switch module 100 displays the specific display interface of writing the model code, indicating that the range hood is in a state of being able to write the model code, the model code reading and writing tool 200 is aligned with the body sensing unit of the switch module 100, the model code reading and writing tool 200 emits the model code infrared signal through the second infrared emitter 230, the first infrared receiver 120 receives the model code infrared signal, the first control unit 110 judges whether the range hood is writing the model code for the first time, if yes, the model code will be written and memorized on the electronic board, after the writing is completed, the interface is exited, and the process is ended; if not, an alarm will be prompted, the user can end the operation, or if it is necessary to write again after the alarm is prompted, the model code can be reset by combining long press key, and the model code reading tool 200 is used to write again. Figure 2 As shown, the model code reading process is as follows: the package of the range hood is disassembled, and the range hood is powered on, the key on the switch module is combined and long pressed to enter the model code reading program, the switch enters the reading program and displays the interface, and emits the model code infrared signal, the model code reading and writing tool 200 is aligned with the range hood, and the model code is read, if the reading is successful, the model code reading and writing tool emits a prompt sound, and displays the model code; if the reading is not successful, the key unit is used to enter the model code reading program again, and the model code reading and writing tool is used to read again.
