[0044] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0046] For the convenience of describing the first, second, and third directions in the embodiments of this application, the first direction is the left-right direction in the drawings, the second direction is the front-back direction in the drawings, and the third direction is the up-down direction in the drawings. The x-axis arrow direction is referred to as the "right" direction, the y-axis arrow direction is referred to as the "up" direction, and the z-axis arrow direction is referred to as the "back" direction in the following text. However, in the actual application of this application, this is not limiting.

[0047] like Figure 3-6 As shown, this embodiment provides a ventilation device for hospital infection prevention and control and an outpatient building, which includes a main body 110, an air supply mechanism 120, an air dispersion mechanism 130, and a monitoring mechanism 140. The main body 110 is provided with an air inlet 111 and an air outlet 112. The air supply mechanism 120 is mounted on the main body 110 and is used to increase the air flow rate between the air inlet 111 and the air outlet 112; that is, the air supply mechanism 120 is used to provide blowing air to ensure air flow. The air dispersion mechanism 130 is mounted on the main body 110 and is used to disperse the air generated by the air supply mechanism 120. The monitoring mechanism 140 is used to monitor the air flow rate between the air inlet 111 and the air outlet 112. When the air flow rate at the air inlet 111 and / or the air outlet 112 decreases, the monitoring mechanism 140 controls the air supply mechanism 120 to operate. When the air flow rate at the air inlet 111 and / or the air outlet 112 is normal, the monitoring mechanism 140 stops the air supply mechanism 120. That is, the air flow rate between the air inlet 111 and / or the air outlet 112 is continuously monitored by the monitoring mechanism 140, and then the air supply mechanism 120 is controlled to operate according to the flow rate, and finally the air is dispersed by the air dispersion mechanism 130; using the above method, the air flow rate at the air inlet 111 and / or the air outlet 112 is continuously controlled, and the air flow rate between the air inlet 111 and / or the air outlet 112 is guaranteed, thereby preventing the spread of disease.

[0048] In this embodiment, the air supply mechanism 120 includes a first air supply device 121 and a second air supply device 122. The first air supply device 121 is located at the air inlet 111 and points to the air outlet 112; the second air supply device 122 is located between the air inlet 111 and the air outlet 112 and points to the air outlet 112; when the air flow rate at the air inlet 111 is low, the first air supply device 121 works; when the air flow rate at the air outlet 112 is low, the second air supply device 122 works. The arrangement of the first and second air supply devices, that is, the use of multiple air supply devices, is used. The multiple air supply devices are respectively arranged at corresponding positions between the air inlet 111 and the air outlet 112 to ensure the air flow rate at each position and to ensure that there is no dead corner between the air inlet 111 and the air outlet 112 where air does not flow.

[0049] In this embodiment, the air dispersing mechanism 130 includes a first air dispersing device 131 and a second air dispersing device 132. The first air dispersing device 131 is installed on the side of the first air supply device 121 located at the air outlet 112 to disperse the air generated by the first air supply device 121. The second air dispersing device 132 is installed on the side of the second air supply device 122 located at the air outlet 112 to disperse the air generated by the second air supply device 122. In other words, by installing a air dispersing device at each air supply device and dispersing the air generated by the air supply device through the air dispersing device, the generated air can be effectively dispersed to any location between the air inlet 111 and the air outlet 112, thus preventing the problem of dead angles.

[0050] like Figure 1 As shown, in this embodiment, the first air supply device 121 and the second air supply device 122 each include a support member 12a, fan blades 12b, and a motor 12c. The support member 12a is mounted within the main body 110, and the fan blades 12b and motor 12c are both mounted on the support member 12a. The motor 12c is capable of driving the fan blades 12b to rotate. Using a motor to drive the fan blades for air blowing occupies little space and is convenient to use.

[0051] like Figure 1-2 As shown, in this embodiment, the first air dispersing device 131 and the second air dispersing device 132 each include a first air dispersing member 13a and a second air dispersing member 13b. The first air dispersing member 13a initially disperses the air generated by the air supply mechanism 120. The second air dispersing member 13b is installed on the side of the first air dispersing member 13a away from the air supply mechanism 120 and further disperses the air dispersed by the first air dispersing member 13a. The first air dispersing member 13a disperses the air to the corresponding location, while the second air dispersing member further disperses the air within the first air dispersing member. This ensures a more uniform wind speed between the air inlet 111 and the air outlet 112 while maintaining the same wind speed between the air inlet 111 and the air outlet 112.

[0052] like Figure 1-2 As shown, in this embodiment, the first air dispersing member 13a is composed of multiple pipes; one end of each pipe points toward the air supply mechanism 120, and the other ends of each pipe diverge in all directions, all pointing in the direction of the air outlet. The second air dispersing member 13b is a grille plate, with partitions on the side of the grille plate away from the air supply mechanism 120 tilted in all directions. When air passes through the grille plate, the tilted partitions divert the air in different directions. In other words, the pipes disperse the air blown from the air supply mechanism, and then the grille plate diffuses the air a second time. This secondary diffusion of air is more uniform, preventing the problem of a single air path causing air to directly reach the patient, worsening their condition.

[0053] like Figure 5 As shown, in this embodiment, the number of monitoring mechanisms 140 is the same as the number of air supply mechanisms 120, and each monitoring mechanism 140 is located on the side of a corresponding air dispersion mechanism 130 away from the air supply mechanism 120. When the wind speed decreases, the monitoring mechanism 140 controls the operation of the corresponding air supply mechanism 120. In other words, each monitoring mechanism 140 controls a corresponding air dispersion mechanism 130, ensuring that air flow is maintained at every position between the air inlet 111 and the air outlet 112.

[0054] like Figure 5 As shown, in this embodiment, monitoring mechanism 140 includes an anemometer 141 and a controller 142. Anemometer 141 is used to detect wind speed, and controller 142 can control the speed of motor 12c based on the wind speed detected by anemometer 141. In other words, when wind blows on anemometer 141, anemometer 141 can monitor the wind speed and transmit the measured wind speed to controller 142. Controller 142 can analyze the wind speed. When the wind speed is low, controller 142 controls motor 12c to start, causing fan blades 12b to fan.

[0055] like Figure 3-5 As shown, in this embodiment, the outpatient building comprises a ceiling 11a, patient rooms 11b, and a floor 11c. The patient rooms 11b divide the building into an outpatient lobby, a corridor, a main entrance, a side entrance, and a rear entrance. The main entrance corresponds to the outpatient lobby, and the side entrance corresponds to the corridor. Air inlet 111 is the main entrance, and air outlet 112 is the side and rear entrances. Air flows through the main entrance into the outpatient lobby and corridor, and finally out through the side and rear entrances.

[0056] In summary, the utility model provides a ventilation device and an outpatient building for hospital infection prevention and control, which monitors the air flow rate between the air inlet and / or air outlet through a monitoring mechanism, then controls the air supply mechanism to operate according to the flow rate, and finally disperses the wind through the air dispersion mechanism to prevent the spread of the disease.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
