[0001] The present application relates to the technical field of indoor ventilation, in particular to a hotel decoration ventilation device. BACKGROUND

[0002] The main pollutants in the air during hotel decoration are formaldehyde, benzene, volatile organic compounds, etc., which need to be gradually reduced by maintaining sufficient ventilation. However, the hotel decoration generally needs to achieve the requirement of rapid occupancy, so it is obviously insufficient to use normal natural ventilation to reduce air pollutants.

[0003] Therefore, there is an urgent need for a ventilation device that can quickly reduce indoor air pollutants to meet the requirement of rapid occupancy after hotel decoration. CONTENT OF THE INVENTION

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] like Figures 1-4 As shown, a hotel renovation ventilation device according to an embodiment of this application includes an air exchange cylinder 1, a connecting cylinder 11 sealed at the top of the air exchange cylinder 1, an exhaust cylinder 12 sealed at the bottom of the air exchange cylinder 1, and a hemispherical cover 13 rotatably fitted at the top of the connecting cylinder 11; an air extraction component is coaxially arranged inside the air exchange cylinder 1.

[0023] The connecting cylinder 11 is sealed at the top of the air exchange cylinder 1, making it easy to disassemble the air exchange cylinder 1 and the connecting cylinder 11. Similarly, the exhaust cylinder 12 is sealed at the bottom of the air exchange cylinder 1, making it easy to disassemble the exhaust cylinder 12 and the air exchange cylinder 1.

[0024] It should be noted that the hemispherical cover 13 at the top of the connecting cylinder 11 can only rotate on the connecting cylinder 11 to prevent accidental contact during use that could cause the hemispherical cover 13 to fall off.

[0025] Specifically, an exhaust pipe 121 is connected to the side wall of the exhaust pipe 12, and an external hose can be connected to the exhaust pipe 121, with the outlet of the external hose placed outdoors, so that the air drawn from the room can be discharged outdoors.

[0026] It should be noted that, as Figure 3 and Figure 4 As shown, a plurality of through-holes 131 are evenly arranged on the hemispherical cover 13 so that when the exhaust pipe 12 generates suction in the direction of the hemispherical cover 13, the air outside the hemispherical cover 13 can be drawn into the exhaust pipe 12 through these holes 131.

[0027] It should be further noted that the spherical design of the hemispherical cover 13 can increase the adsorption area and improve the coverage of the suction without changing the power equipment of the ventilation device, thus enhancing the emission efficiency of indoor air pollutants to a certain extent.

[0028] like Figure 2 and Figure 4 As shown, multiple blades 132 are uniformly fixed to the inner circumference of the hemispherical cover 13, and the blades 132 are inclined in both the axial and radial directions of the air exchange cylinder 1.

[0029] Therefore, it can be understood that the multiple blades 132, which are inclined in both the axial and radial directions, will generate rotational potential energy in the hemispherical cover 13 under the action of the airflow entering the hemispherical cover 13. Ultimately, under the action of this potential energy, the hemispherical cover 13 will rotate. The speed of rotation is related to the magnitude of the suction force (i.e., the speed of the airflow). Thus, it can be further understood that the hemispherical cover 13 will gradually rotate during the process of adsorbing indoor air in the hotel until the equipment stops operating. During this process, the rotating hemispherical cover 13 will form a suction force with virtually no dead angles within its spherical coverage area. This will further enhance the adsorption effect and rate of the ventilation equipment on indoor air pollutants in the hotel.

[0030] The air extraction component mentioned above is power assembly 2, such as... Figure 2 and Figure 3 As shown, the power assembly 2 includes a motor 21 coaxially fixed inside the air exchange cylinder 1, and the output end of the motor 21 is keyed to a fan blade 22.

[0031] It should be noted that the fan blade 22 is designed so that the side that generates suction faces the hemispherical cover 13.

[0032] Among them, a bracket 211 is coaxially fixed to the motor 21, and the bracket 211 is inserted into the air exchange cylinder 1 for limiting.

[0033] like Figure 3 As shown, a limiting ring 14 is coaxially fixed to the upper half of the inner side of the air exchange cylinder 1 to provide circumferential limiting for the bracket 211.

[0034] like Figure 2 and Figure 3 As shown, a dustproof net 23 is provided on the side of the motor 21 away from the fan blade 22, and the dustproof net 23 is inserted into the air exchange cylinder 1 for limiting.

[0035] The dustproof net 23 is set on the side of the air exchange cylinder 1 facing the connecting cylinder 11. This design can filter the debris in the airflow entering the air exchange cylinder 1 to a certain extent, and prevent the debris from interfering with the motor 21 and the fan blade 22.

[0036] like Figure 1 and Figure 2 As shown, a hemispherical interception net 3 is provided on the outer side of the hemispherical cover 13, and a support rod 31 is coaxially fixed to the inner side of the hemispherical interception net 3. The support rod 31 rotates through the hemispherical cover 13 and is coaxially inserted into the dustproof net 23.

[0037] It should be noted that, in the specific embodiments of this application, the mesh size of the hemispherical interceptor net 3 is larger than that of the dustproof net 23. The hemispherical interceptor net 3 can intercept larger debris in the airflow from the outside, preventing larger debris from reaching the outer surface of the hemispherical cover 13 with the airflow and blocking the air vents 131, thus affecting the adsorption range of the hemispherical cover 13 and also affecting the emission effect of the entire ventilation device on pollutants in the hotel indoor air.

[0038] It should be further noted that casters or suction cups can be added to the bottom of the exhaust pipe 12 of the ventilation device to facilitate the placement of the ventilation device in different locations inside the hotel.

[0039] It should be noted that the specific models and specifications of the motor 21, fan blades 22 and dustproof net 23 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0040] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
