These visual displays allow monitors to more clearly understand the information provided by the ventilator, facilitate a more intuitive understanding of the user, and assist medical staff in making accurate judgments and decisions.

[0003] The prior art publication number is CN215586973U, and its name is a display screen device for a ventilator. The installation of the liquid crystal display screen on the ventilator is fixed by glue. This patent cooperates with the installation cavity and the docking frame. The worker only needs to fill the installation cavity between the second limit frame and the first limit frame with glue, and then insert the docking frame into the installation cavity with glue, and at the same time, the installation frame is inserted into the installation port, and the display screen is installed. The second limit frame and the first limit frame can limit the location of glue application, so that the worker can only apply glue in the installation cavity. The gluing operation is simple, which avoids the situation where the worker is not skilled in gluing and the glue is applied to other positions of the display screen for cleaning and re-applying. The docking frame and the installation frame are easy to install, thereby improving the installation efficiency of the display screen and the front shell of the ventilator.

[0004] However, the above-mentioned display screen equipment for ventilators has the following problems: the LCD screen is fixed by glue, and after long-term use, the glue may fail and the screen may not be firmly installed; in addition, when the screen fails, the glue fixing method will make it difficult to disassemble for maintenance or replacement.

[0028] See also Figures 1 to 5 A ventilator display screen device includes: a display screen 1, a first shell 2 and a second shell 3.

[0029] The first housing 2 has an opening 21 for exposing the display screen 1 and a first recess 22 connected to the opening 21. Bosses 23 are provided on the top and bottom outer sides of the first housing 2, respectively. At least the bottom and top of the first housing 2 are elastic. The second housing 3 has a second recess 32. The first and second recesses 22 and 32 form a confined space for mounting the display screen 1. The top and bottom inner walls of the second housing 3 each have a slot 33 that mates with the boss 23. The boss 23 engages within the slot 33. When the first and second housings 2 and 3 are combined, the display screen 1 is mounted within the confined space. Specifically, the second housing 3 has threaded mounting holes for screw attachment to the ventilator body. The opening 21 is sized to fit the active display portion of the display screen 1, so as not to obstruct the display. The circumferential edge of the first housing 2 is folded toward the second housing 3. A prism 25 is provided along the circumference of the opening 21, dividing the first housing 2 into the first recess 22 and the third recess 26. The first housing 2 is made of plastic, resulting in a flexible bottom and top structure that allows for slight deformation in response to external forces. Preferably, three bosses 23 are respectively provided on the top outer side and the bottom outer side of the first shell 2, and a corresponding number of slots 33 are respectively provided on the top inner wall and the bottom inner wall of the second shell 3. Preferably, the second shell 3 is made of plastic.

[0030] The utility model relates to a display screen device for a ventilator. When assembling, the second shell 3 is first fixedly installed on the main body of the ventilator, the display screen 1 is installed in the second groove 32, and the bottom boss 23 of the first shell 2 is aligned and installed in the bottom card slot 33 of the second shell 3. Since the first shell 2 is elastic, the top boss 23 of the first shell 2 is pressed into the top card slot 33 of the second groove 32 with a certain force. In this way, the display screen 1 is fixedly installed between the first shell 2 and the second shell 3, and in the limited space formed by the first groove 22 and the second groove 32, the display screen 1 can be fixed without applying glue. When disassembling, a flat tool is used to press down and pull outward the top of the first shell 2. Since the first shell 2 is elastic, the top boss 23 is disengaged from the card slot 33. Then, the bottom of the first shell 2 is pulled upward, and the bottom boss 23 is disengaged from the card slot 33. Thus, the first shell 2 is separated from the second shell 3, making it convenient to replace the display screen 1 or other components.

[0031] See also Figure 4 and Figure 5 Furthermore, to facilitate removal or assembly of the first housing 2 from the second housing 3, the cross-section of the boss 23 is a right-angled trapezoid, and the height of the boss 23 is equal to the depth of the slot 33. Specifically, the side length of the upper end surface of the boss 23 is shorter than the side length of the lower end surface, the inclined surface leans toward the second housing 3, and the length between the inner walls of the slot 33 is slightly longer than the length of the boss 23.

[0032] See also Figure 1 and Figure 2 Furthermore, the end surface of the first housing 2 proximate to the second housing 3 is provided with mounting posts 24, and the second housing 3 is provided with mounting holes 34 that mate with the mounting posts 24. The mounting posts 24 are inserted and installed in the mounting holes 34. Specifically, the mounting posts 24 are symmetrically provided on both sides of the end surface of the first housing 2 proximate to the second housing 3. Preferably, there are three mounting posts 24 on each side. The outer diameter of the mounting posts 24 is equal to the inner diameter of the mounting holes 34, and the length of the mounting posts 24 is equal to the depth of the mounting holes 34. The mounting holes 34 are provided with blocking end surfaces 342 to prevent the mounting posts 24 from being excessively inserted into the mounting holes 34. During insertion and installation, the outer walls of the mounting posts 24 rub against the inner walls of the mounting holes 34. The friction prevents the first housing 2 from colliding with the second housing 3 too quickly, thereby protecting the second housing 2 and the display screen 1. With this structure, the mounting holes 34 not only serve as position markers during installation, facilitating the positioning and installation of the first housing 2, but also restrict movement and rotation between the first and second housings 2 and 3 after the first housing 2 is installed on the second housing 3.

[0033] See also Figure 1 and Figure 2Furthermore, a through-hole 341 is provided at the bottom of the mounting post 34. Specifically, a through-hole 341 is provided through the blocking end surface 342. The inner diameter of the mounting post 34 is much larger than the inner diameter of the through-hole 341. During insertion and installation, air remains within the mounting post 34. This air is squeezed out from the large space into the small hole, securing the mounting post 24. The inner diameter of the through-hole 341 is 1 / 5-1 / 2 of the inner diameter of the mounting post 34. Preferably, the inner diameter of the through-hole 341 is 1 / 4 of the inner diameter of the mounting post 34.

[0034] See also Figure 1 and Figure 2 Furthermore, a layer of anti-collision pad is respectively provided on the four inner walls of the first groove 22 and the four inner walls of the second groove 32, and the display screen 1 is installed in the anti-collision pad, and the thickness of the display screen 1 is equal to the sum of the depth of the first groove 22 and the depth of the second groove 32. Preferably, the anti-collision pad has a certain elasticity, and the display screen 1 is installed in the anti-collision pad, and the elasticity of the anti-collision pad is used to clamp the display screen 1, and when the display screen 1 is installed, the inner walls of the first groove 22 and the second groove 32 are prevented from making rigid contact with the display screen. The second groove 32 is provided, which not only serves as a limit mark for the display screen 1 during installation, facilitating the positioning and quick installation of the display screen 1, but also restricts the movement of the display screen 1 with the assistance of the first groove 22 after installation. The first groove 22 and the second groove 32 constitute a limiting space, thereby fixing the display screen 1 in the limiting space, and limiting the circumferential movement of the six end faces of the display screen 1.

[0035] See also Figure 1 and Figure 2 Furthermore, to strengthen the support provided by the second housing 3 on the display screen 1, the second housing 3 includes first reinforcing ribs 35, which are mounted on the end face of the second housing 3 facing away from the first housing 2. To enhance the strength of the first housing 2 and reduce damage to the first housing 2 from external forces, the end face of the first housing 2 facing the second housing 3 is provided with multiple sets of second reinforcing ribs 27. The second reinforcing ribs 27 are spaced apart along both sides of the opening 21, with one end of the second reinforcing ribs 27 connected to the inner wall of the edge of the first housing 2 and the other end connected to the prism 25.

[0036] See also Figure 1 Furthermore, to prevent the display screen 1 from falling during subsequent assembly or disassembly after it is mounted on the second housing 3, double-sided tape 31 is provided on the end surface of the second housing 3 that contacts the display screen 1. The double-sided tape 31 is made of 3M adhesive, which has a small area and only requires pre-fixing the display screen 1, without affecting the difficulty of disassembling the display screen 1.

[0037] The utility model provides a ventilator display screen device, which forms a limiting space by providing a matching first groove 22 and a second groove 32. The second groove 32 not only serves as a limiting mark for the display screen 1 during installation, facilitating the positioning of the display screen 1 and allowing for quick installation, but also, after installation, with the assistance of the first groove 22, restricts its movement from the six end faces of the display screen 1, preventing the display screen 1 from falling off after the glue is ineffective when fixed by glue. Mounting posts 24 and mounting hole posts 34 are provided to limit the movement of the first shell 2 and the second shell 3, ensuring the stability of the display screen 1. During installation, the first shell 2 is subjected to structural resistance, preventing the first shell 2 from colliding with the second shell 3 too quickly, thereby protecting the second shell 2 and the display screen 1. Bosses 23 and slots 33 are provided. When the bosses 23 and slots 33 are engaged, not only the stability between the first shell 2 and the second shell 3 is increased, but also the elastic action of the edge of the first shell 2 facilitates the replacement of the display screen 1 or other components. A first reinforcing rib 35 is provided on the second shell 3, and a second reinforcing rib 27 is provided on the first shell 2, increasing the ability of the display screen 1 to resist external forces.
