[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] Example 1: Figure 1-3 , including a unit shell 100, a ventilation pipe 110 is fixedly installed on the inner wall of the unit shell 100, a vacuum generator 120 is fixedly connected to the outer side of the ventilation pipe 110, a filter screen 140 is installed at the input end of the vacuum generator 120, an air pump support seat 150 is fixedly installed on the outer wall of the front end of the unit shell 100, a high-pressure air pump 160 is fixedly connected to the top of the air pump support seat 150, a quick-connect interface 121 is fixedly installed on the outer wall of the vacuum generator 120, an output end of the high-pressure air pump 160 is fixedly connected to the quick-connect interface 121 through a conduit 161, a temperature adjustment component is fixedly installed at the output end of the ventilation pipe 110, the temperature adjustment component includes an air inlet pipe 200 and a heating ring 242, and a humidifier is provided at the rear end of the heating ring 242.

[0027] The specific use scenario of this embodiment is as follows: the working principle of the vacuum generator 120 is to provide a positive pressure airflow to the quick-connect connector 121 on the outer wall of the vacuum generator 120 by turning on the high-pressure air pump 160. The positive pressure airflow passes through the Laval nozzle inside the vacuum generator 120, then enters the receiving tube, and then discharges the airflow through the air outlet pipe 1225. In this process, a negative pressure is formed in the negative pressure chamber in the vacuum generator 120. When the air supply pressure of the air supply port is higher than a certain value, the nozzle ejects a supersonic jet. Due to the viscosity of the gas, the high-speed jet sucks away the gas in the negative pressure chamber, so that the chamber forms a very low vacuum degree, so that the air in the environment enters the interior of the ventilation pipe 110, so that the high-pressure air pump is installed outdoors, so that the fresh air unit can reduce the noise impact on the room when it is working, and improve the indoor quiet effect. By setting the temperature adjustment component and the humidifier for use, it is convenient to adjust the temperature and humidity of the air entering the room.

[0028] Example 2: Figure 1 and Figure 2 An air outlet pipe 122 is provided on the outer wall of the vacuum generator 120, and a one-way valve is installed on the inner wall of the air outlet pipe 122. The input end of the vacuum generator 120 is fixedly connected to the holder 130. A slot 131 is provided on the inner wall of the holder 130. The filter screen plate 140 is plugged and installed inside the slot 131. Filter holes are provided on the surface of the filter screen plate 140. The outer wall at the top of the filter screen plate 140 is fixedly connected to the handle 141.

[0029] The specific usage scenario of this embodiment is: by providing a detachable and plug-in filter plate 140, the effect of filtering large particles in the air can be improved, thereby saving the loss of the filter element and improving the protection of indoor air. By providing a handle 141, the filter plate 140 can be easily removed for cleaning.

[0030] Example 3: Figure 4 and Figure 5 The air inlet pipe 200 is detachably fixedly connected to the input end of the ventilation pipe 110 by screws, a filter screen 210 is fixedly installed on the inner wall of the air inlet pipe 200, the filter screen 210 is made of metal, a filter element 220 is plugged and installed on the inner wall of the input end of the air inlet pipe 200, and a heating ring positioning frame 240 is fixedly installed on the outer wall of the output end of the air inlet pipe 200. The inner wall of the heating ring positioning frame 240 is evenly provided with card grooves 241, and the inner wall of the card groove 241 cooperates with the plug-in installation of a heating ring 242, and the heating ring 242 is set to be spring-shaped.

[0031] The specific usage scenario of this embodiment is as follows: the heating ring 242 is made of metallic copper, and a resistance wire structure is arranged inside the heating ring 242. By energizing the resistance wire, the heating ring 242 generates heat to heat the passing air, thereby avoiding heating the air when the temperature is too low in winter, thereby regulating the indoor temperature and improving the indoor temperature comfort.

[0032] Example 4: Figure 3 and Figure 4 The humidifier includes a water tank 300, the outer wall of the water tank 300 is fixedly installed on the outer wall of the unit shell 100 through a support frame 350, the top of the water tank 300 is connected to the humidifying tube 250 through a second conduit, the humidifying tube 250 is detachably fixedly connected to the end of the air inlet pipe 200 by screws, the output end of the humidifying tube 250 is plugged and installed with a breathable cover plate 261, a visual window 310 is fixedly installed on the front inner wall of the water tank 300, a filling pipe 320 is fixedly installed on the top outer wall of the water tank 300, a top cover is installed on the top of the filling pipe 320, an operation button 330 is fixedly installed on the top outer wall of the water tank 300, and an ultrasonic vibrator 340 is fixedly installed on the bottom inner wall of the water tank 300.

[0033] The specific usage scenario of this embodiment is: by setting a water tank 300 for holding pure water for humidifying the indoor air, thereby preventing the air from being too dry, by setting an ultrasonic vibrator 340 for high-frequency vibration of the pure water to generate water mist, the air is humidified, and the efficiency of mixing with the air is improved.

[0034] The working principle of the utility model is as follows: when in use, a person skilled in the art installs the unit housing 100 on the inner wall of the indoor window glass, so that the vacuum generator 120, the filter screen 140, and the high-pressure air pump 160 are located on the outside of the window, opens the top cover on the top of the filling pipe 320, and fills a proper amount of pure water into the water tank 300. By turning on the high-pressure air pump 160, the high-pressure air pump 160 delivers a high-pressure airflow to the inside of the vacuum generator 120, so that a negative pressure is formed inside the negative pressure chamber inside the vacuum generator 120, so that the outdoor air is sucked into the inside of the ventilation pipe 110 under the action of the negative pressure, and is filtered when passing through the filter screen 140. The mesh plate 140 filters large particles of impurities in the air, and then the air flow is filtered again through the filter element 220 to remove tiny impurities in the air, and further removes impurities in the air. When the temperature is too low, the heating ring 242 is energized so that the heating ring 242 heats the air to a suitable temperature. When the air is relatively dry, the ultrasonic vibrator 340 is turned on so that the ultrasonic vibrator 340 vibrates at a high frequency, so that the water in the water tank 300 is vibrated and atomized, and a large amount of water vapor enters the humidification tube 250, mixes with the air, and humidifies the air, thereby achieving temperature and humidity regulation of indoor fresh air.

[0035] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
