[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-3 As shown, one aspect of this utility model discloses a wall ventilator, comprising: Air duct 1, air duct 1 is inserted into a pre-drilled hole in the wall, and a fan module 2 for pressing air into the wall is provided at one end of air duct 1 near the wall. A filter module 3 is also provided inside the air duct. Filter module 3 is used to filter pollutants in the air; Fan module 2 is used to deliver clean air filtered by filter module 3 into a confined space; And a signal detection feedback module 4 installed in the duct 1, which is used to detect whether the feedback filtering module 3 and the fan module 2 are operating normally.

[0020] Compared with the prior art, this application has the following advantages: When in use, the fan module 2 works to force air into the wall through the air duct 1, and the air enters the room after being filtered by the filter module 3; at the same time, the signal detection feedback module 4 continuously detects whether the filter module 3 and the fan module 2 are working properly. If the filter module 3 or the fan module 2 is detected to be working malfunctioning, it will promptly send a signal to the control system to remind the operator to check and repair it, thereby avoiding the occurrence of biosecurity problems caused by unfiltered air entering the pig house.

[0021] Following the above embodiments, more specifically, the filter module 3 includes a filter composed of multiple layers of filter materials with different densities. The filter material can be non-woven fabric, which can effectively filter out dust, pollen, pathogenic microorganisms (such as African swine fever virus, PRRS virus, etc. attached to particulate matter), mosquitoes and flies in the air, thereby providing clean and safe air for livestock and poultry in the house and greatly reducing the risk of disease transmission.

[0022] Following the above embodiments, more specifically, the fan module 2 includes a positive pressure air supply device; wherein the positive pressure air supply device includes a centrifugal fan, which draws in air from the outside and generates sufficient pressure to force the air through subsequent filtration and regulation equipment, and finally delivers it into the room. Its power and air pressure are much higher than those of the negative pressure fan, so as to overcome the resistance of subsequent components.

[0023] Following the above embodiments, more specifically, as Figure 2 , Figure 3As shown, the signal detection feedback module includes a wind deflector 5 and a magnetic switch 6. One end of the wind deflector 5 is hinged to one end of the air duct 1, and the other end is suspended near the magnetic switch 6. The magnetic switch 6 is located at the other end of the air duct 1 so that when the air duct 1 is ventilated, the wind deflector 5 is driven to rotate, thereby triggering the magnetic switch 6.

[0024] The magnetic switch 6 can be a reed switch magnetic switch, and a magnet is installed on the baffle plate 5. When the centrifugal fan is not running, the baffle plate 5 will be close to the magnetic switch 6, and the magnetic switch 5 will be turned on. When the centrifugal fan is running, the baffle plate 5 will rotate away from the magnetic switch 6 under the action of the wind, and the magnetic switch 6 will be turned off. Based on this, if the centrifugal fan is running and the magnetic switch 6 is not turned off, it means that there is no air in the air duct 1 or the air force is too weak, which indicates that either the centrifugal fan is malfunctioning or the filter is clogged. It will then send a signal to the control system, which will then alarm to remind the staff.

[0025] Following the above embodiment, more specifically, a rain cap 7 is provided at the end of the duct 1 away from the wall. The rain cap 7 is inserted into the duct 1. Through the design of the rain cap 7, rainwater from the outside is prevented from being blown into the duct 1 by wind or other forces during rainy weather.

[0026] Preferably, a sealing ring is provided between the rain cap 7 and the air duct 1. The design of the sealing ring reduces the air leakage at the connection between the two.

[0027] Another aspect of this application discloses a bathroom, such as Figure 4 As shown, the wall ventilator 8 mentioned above is installed on one side of the shower room to supply air into the shower room. The shower room is a crucial disinfection step before personnel enter the pigsty, so for biosecurity reasons, personnel must shower and change clothes before entering the pigsty. To ensure air quality in the shower room, the aforementioned wall ventilator 8 is used. This positive pressure ventilation system supplies filtered clean air into the shower room and also uses positive pressure to compress air outwards, ensuring that outside air does not enter, thus preventing biosecurity issues caused by outside air entering the shower room.

[0028] Following the above embodiment, more specifically, the bathing room includes a dirty area 9, a shower area 10, and a clean area 11. The entrance of the shower area 10 is connected to the dirty area 9, and the exit of the shower area 10 is connected to the clean area 11. Personnel first enter the dirty area 9 to take off their dirty clothes, then shower in the shower area 10, and finally change into new clothes in the clean area 11 before entering the pigsty. Therefore, by separating dirty and clean areas, the cross-contamination of dirty and new clothes is avoided, effectively improving biosecurity.

[0029] Following the above embodiments, more specifically, wall ventilators 8 are installed in the dirty area 9, the shower area 10 and the clean area 11 respectively, or wall ventilators 8 are installed in one of the dirty area 9, the shower area 10 and the clean area 11, as long as the total ventilation volume and air exchange rate of the bathroom can be met and the overall ventilation of the bathroom can be guaranteed.

[0030] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
