The PCB board 4 is disposed on the fixing bracket 13. In this embodiment, the cooperation between the base shell 1 and the top cover 5 forms a closed mounting cavity 11, which provides good protection for key components such as the internal air pump element 2 and PCB board 4, effectively preventing the intrusion of harmful factors such as external dust and moisture, thereby extending the service life of the overall device. Meanwhile, this enclosed design also enhances the device's anti-interference capabilities, ensuring the accuracy of blood pressure measurement. Regarding the fixing of the air pump element 2, the mechanism innovatively employs a combination of air pump fixing slot 12 and fixing slot 14. The air pump fixing slot 12 provides a precise installation position for the air pump element 2, ensuring the stability of the air pump during operation. The cooperation between the fixing slot 14 and the fixing element 3 further enhances the fixing effect of the air pump element 2, preventing loosening or displacement due to vibration or external forces, thereby ensuring that the air pump can continuously and stably provide the required air pressure, providing reliable power support for blood pressure measurement.

[0026] A mating step 15 is provided on the outer side of the bottom shell 1, which is used for the mating installation of the top cover 5. Specifically, a mating buckle 151 is provided on the mating step 15, and a mating groove 51 is provided on the top cover 5, which is used to engage the mating buckle 151. In this embodiment, the mating step 15 cleverly designed on the outer side of the bottom shell 1 demonstrates its exquisite design and practicality. This mating step 15 not only serves as a structural transition, but more importantly, it provides a solid foundation for the precise mating installation of the top cover 5. Specifically, the carefully designed mating buckle 151 on the mating step 15 perfectly matches the mating groove 51 on the top cover 5. This buckle and groove connection method not only ensures a stable connection between the top cover 5 and the bottom shell 1, but also greatly simplifies the installation process and improves assembly efficiency.

[0027] The mounting cavity 11 is provided with an assembly positioning post 111, and the upper cover 5 is provided with an assembly connecting post 52. The assembly positioning post 111 is provided with a positioning groove 112, which is used to cooperate with the assembly connecting post 52. In this embodiment, the assembly positioning post 111 not only provides a precise reference point for fixing the air pump, but also achieves a stable connection with the assembly connecting post 52 of the upper cover 5 through its structural optimization. This connection method not only enhances the stability of the air pump fixing mechanism, but also effectively avoids loosening or displacement that may occur during use, thereby ensuring the accuracy and reliability of the electronic blood pressure monitor's measurement results. In addition, the design of the positioning groove 112 on the assembly positioning post 111 cleverly matches the shape of the assembly connecting post 52, enabling the two to be quickly and accurately positioned during assembly, greatly improving assembly efficiency. At the same time, the presence of the positioning groove 112 also plays a certain guiding role, making the assembly process smoother and avoiding damage to the air pump fixing mechanism caused by improper assembly.

[0028] A battery compartment 113 is located below the mounting cavity 11 in the bottom shell 1.

[0029] The air pump mounting slot 12 is equipped with a support frame 121, which has a positioning groove 122. The positioning groove 122 is opposite to the fixing element 3 and fixes one end of the air pump element 2. In this embodiment, the carefully arranged positioning groove 122 on the support frame 121 not only forms a precise correspondence with the fixing element 3, but also firmly fixes one end of the air pump element 2 through physical fitting. The cooperation between the positioning groove 122 and the fixing element 3 effectively prevents the air pump from shaking or shifting during operation, thereby ensuring the stability and accuracy of the air pump output. This is crucial for electronic blood pressure monitors, as any slight deviation can affect the accuracy of blood pressure measurement.

[0030] A threaded post 123 is provided on one side of the air pump mounting groove 12 opposite to the mounting slot 14. A fixing buckle 31 is provided on one side of the fixing element 3, and a fixing ring 32 is provided on the other side.

In this embodiment, the threaded post 123 is cleverly designed on the opposite side of the air pump mounting groove 12 and the mounting slot 14. This design not only enhances the stability of the structure but also makes it possible to achieve precise fixing of the air pump element 2. The design of the fixing element 3 is also ingenious. The fixing buckle 31 on one side can be precisely engaged in the mounting slot 14, ensuring the air pump is stable and does not wobble in the horizontal direction. The fixing ring 32 on the other side forms a perfect cooperation mechanism with the threaded post 123. By rotating the fixing ring 32, the air pump element 2 can be tightly locked in the vertical direction, effectively avoiding loosening caused by vibration or long-term use. This fixing mechanism is not only compact and easy to operate, but also significantly improves the fixing effect and stability of the air pump in the electronic blood pressure monitor, providing a strong guarantee for the accurate measurement of blood pressure.

[0031] The fixing bracket 13 is provided with threaded holes 131, and the PCB board 4 is fixed to the threaded holes 131 by screws. The fixing bracket 13 is used to support the PCB board 4. In this embodiment, through the tight fit between the screws and the threaded holes 131, the PCB board 4 can be firmly fixed to the fixing bracket 13, effectively preventing the PCB board 4 from loosening or being damaged due to vibration or impact during the operation of the air pump. Secondly, this structure improves the reliability and stability of the air pump fixing mechanism. As a supporting structure for the PCB board 4, the fixing bracket 13 is reasonably designed and easy to install, ensuring the stable operation of the air pump and its related circuit components, thereby improving the measurement accuracy and service life of the entire electronic blood pressure monitor. In addition, this structure facilitates subsequent maintenance and replacement. When it is necessary to repair or replace the PCB board 4, it can be easily removed by simply loosening the screws, greatly simplifying the operation process and reducing maintenance costs.

[0032] The fixing element 3 is provided with an arc-shaped portion 33, which matches the outer arc of the air pump element 2 to fix the air pump element 2. In this embodiment, the arc-shaped portion 33 is precisely designed so that its curvature perfectly matches the outer arc of the air pump element 2, achieving a stable fixation of the air pump element 2. Specifically, this matching design not only enhances the stability of the air pump element 2 during the fixing process, but also effectively reduces vibration and noise caused by improper fixing. During the operation of the blood pressure monitor, the stable operation of the air pump is crucial, and the matching fixing method of the arc-shaped portion 33 provides a strong guarantee for this. In addition, the design of the arc-shaped portion 33 simplifies the structure of the fixing mechanism and reduces production costs. Through simple arc matching, an efficient and reliable fixing effect can be achieved without additional complex mechanisms and parts.

[0033] The top cover 5 is provided with a screen mounting area 53 and a button mounting area 54. In this embodiment, the screen mounting area 53 allows the electronic display screen to be securely embedded, providing users with a clear reading interface and greatly improving the intuitiveness and convenience of operation. At the same time, the design of this area also considers the protection and fixation of the screen, effectively preventing screen damage or malfunction due to vibration or accidental touch. Secondly, the planning of the button mounting area 54 ensures the precise layout and stable installation of each function button. This not only allows users to easily access and accurately operate the buttons when measuring blood pressure, but also improves the durability and lifespan of the buttons. Through reasonable button partitioning and labeling, users can quickly identify and execute the required functions, further enhancing the practicality and user experience of the electronic blood pressure monitor.

[0034] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
