[0002] Digital tube displays are widely used in home appliances, such as washing machines, microwave ovens, ovens, refrigerators, air conditioners, etc. Digital tube displays are often used to display key information such as temperature, time, and working mode. Their intuitive, easy-to-read features and simple and clear operation methods make them an important part of home appliances. Some digital tube displays are composed of a circuit board and multiple separate digital tubes, which are then installed in home appliances and matched with the housing of the home appliances. Since the circuit on the circuit board needs to match the digital tube, the hole design on the circuit board limits the shape and size of the digital tube, making it impossible to flexibly replace digital tubes of different shapes at the same position on the circuit board, resulting in weaker product customization. The digital tube displays corresponding to different home appliances require redesigned circuit boards, which cannot meet diverse market demands and has high production costs. Utility Model Content

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0020] This application discloses a digital tube display screen for household appliances, such as Figure 1 and Figure 2 As shown, it includes a circuit board 1 and several digital tubes 5 of different shapes. Several jacks are provided on the circuit board 1. Several identical mounting bases 2 are provided on the circuit board 1. Pins 3 matching the jacks are provided at the bottom of the mounting base 2. The pins 3 are inserted into the jacks and supported by conductive material. Several interfaces 4 are provided on the mounting base 2. There are two rows of interfaces 4. Digital tubes 5 of different shapes are installed on the interfaces 4 of the mounting base 2. The pins of the digital tubes 5 are electrically connected to the circuit board 1 through the interfaces 4 and the pins 3. Multiple interfaces 4 are provided on the mounting base 2, so that the pins of digital tubes 5 of different shapes or sizes can be inserted into some interfaces 4 on the mounting base 2, so that the mounting base 2 can adapt to digital tubes 5 of different shapes, so that digital tubes 5 of different shapes or sizes can be replaced at the same position of the circuit board 1, thereby improving the flexibility and convenience of installing the digital tubes 5.

[0021] Specifically, each pin 3 corresponds to an interface 4, and the interface 4 is arranged in a rectangular shape. The length direction of the interface 4 is perpendicular to the arrangement direction of the interface 4. The length of the interface 4 is greater than the pin of the digital tube 5. The setting of the rectangular interface 4 allows the pins of digital tubes 5 of different sizes to be inserted into the interface 4, thereby making the installation of the digital tube 5 more flexible. There are bulging elastic connectors 6 on both sides of the interface 4, and the lower end of the elastic connector 6 is connected to the pin 3. The elastic connector 6 is used to contact the pin of the digital tube 5. The minimum gap between the two elastic connectors 6 is smaller than the size of the pin of the digital tube 5. When the pin of the digital tube 5 is inserted into the interface 4, the elastic connector 6 is stretched open. The setting of the elastic connector 6 makes the contact between the interface 4 and the pin of the digital tube 5 more stable, and makes the electrical connection between the digital tube 5 and the circuit board 1 more stable.

[0022] In addition, a buckle 7 is provided at the bottom of the mounting base 2, and a corresponding slot is provided on the circuit board 1. The buckle 7 faces the outside of the mounting base 2, and the buckle 7 is used to engage with the slot. The mounting base 2 is stably mounted on the circuit board 1 through the buckle 7, and the pin 3 of the mounting base 2 is inserted into the socket on the circuit board 1. The setting of the buckle 7 enables the pin 3 to be stably connected to the socket, making the electrical connection between the mounting base 2 and the circuit board 1 more stable.

[0023] The implementation principle of this embodiment is:

[0024] Digital tubes 5 of different shapes are inserted into different interfaces 4 on the mounting base 2, and the pins of the digital tubes 5 contact the elastic connectors 6 in the interfaces 4. At the same time, the elastic connectors 6 are connected to the pins 3. The pins 3 are inserted into the circuit board 1 to realize the electrical connection between the pins of the digital tubes 5 and the circuit board 1, so that the mounting base 2 can adapt to digital tubes 5 of different shapes, so that digital tubes 5 of different shapes or sizes can be replaced at the same position of the circuit board 1, thereby improving the flexibility and convenience of installing the digital tubes 5.
