DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] In order to solve the technical problem of insufficient liquid atomization, the utility model provides a gas-assisted atomizer and a cooling and humidifying device, which can perform two atomization operations on the liquid, thereby avoiding the problem of insufficient liquid atomization.

[0025] It should be noted that the gas-assisted atomizer of the present invention is used for but not limited to cooling and humidifying devices, etc. For the convenience of explanation, in the present invention, only the application of the gas-assisted atomizer to a cooling and humidifying device is used as an example for explanation, and the principle of applying the gas-assisted atomizer to other types of equipment is essentially the same as the principle applied to the cooling and humidifying device, which will not be elaborated here.

[0026] See also Figure 1 The gas-assisted atomizer includes a base barrel 100 and a sleeve 200. The base barrel 100 has a first atomizing chamber 110, and is provided with a liquid inlet 120, an injection hole 130 and a first gas delivery hole 140 connected to the first atomizing chamber 110. The first gas delivery hole 140 is used to introduce a high-speed airflow to atomize the liquid in the first atomizing chamber 110.

[0027] The sleeve 200 is sleeved on the outer periphery of the base tube 100 , and has a second atomizing chamber 210 connected to the injection hole 130 in the sleeve 200 , and a second air supply hole 220 connected to the second atomizing chamber 210 is opened in the sleeve 200 , and the second air supply hole 220 is used to introduce a high-speed airflow to atomize the liquid in the second atomizing chamber 210 .

[0028] In this embodiment, liquid is introduced into the first atomizing chamber 110 through the liquid inlet hole 120, and the first gas delivery hole 140 introduces a high-speed airflow into the first atomizing chamber 110, so that the liquid in the first atomizing chamber 110 is initially atomized by the high-speed airflow, and the airflow carrying the liquid mist enters the second atomizing chamber 210 through the injection hole 130, and the second gas delivery hole 220 introduces a high-speed airflow into the second atomizing chamber 210, and then the airflow carrying the liquid mist can be secondary atomized by the high-speed airflow. With the gas-assisted atomizer provided by the utility model, the liquid undergoes two atomization operations, and the problem of insufficient liquid atomization can be avoided.

[0029] In some of the embodiments, a diverter groove 240 surrounding the base barrel 100 is opened on the inner wall of the sleeve 200, and an injection gap 230 is provided between the sleeve 200 and the base barrel 100. The injection gap 230 connects the diverter groove 240 and the second atomization chamber 210, and the second air delivery hole 220 connects the diverter groove 240.

[0030] In this embodiment, the high-speed airflow introduced by the second air delivery hole 220 flows into the diverter slot 240 and is finally sprayed into the second atomization chamber 210 through the spray gap 230, so that the liquid in the second atomization chamber 210 is atomized.

[0031] In some embodiments, the injection gap 230 is annular and surrounds the injection hole 130 .

[0032] In this embodiment, since the injection gap 230 surrounds the injection hole 130, the airflow ejected from the injection gap 230 is conical and surrounds the airflow carrying liquid mist derived from the injection hole 130, so that the high-speed airflow and the liquid are fully in contact, which is beneficial to the full atomization of the liquid.

[0033] In some embodiments, there are multiple second gas delivery holes 220 , and the multiple second gas delivery holes 220 surround the diversion groove 240 .

[0034] It is understandable that, due to the different distances between the second air delivery holes 220 and various locations in the diverter slot 240, the air pressure in various locations in the diverter slot 240 will be different, which will eventually affect the different air flow speeds derived from various locations in the injection gap 230. By using multiple second air delivery holes 220 to surround the diverter slot 240 and simultaneously deliver air to the diverter slot 240, the air pressure distribution in the diverter slot 240 can be made more uniform, and the corresponding air flow speeds derived from various locations in the injection gap 230 can also be more uniform.

[0035] In some embodiments, one end of the first gas delivery hole 140 is connected to the diversion groove 240 , and the other end thereof is connected to the first atomization chamber 110 .

[0036] In this embodiment, since one end of the first air delivery hole 140 is connected to the diverter slot 240 , the high-speed airflow in the diverter slot 240 can directly enter the first atomizing chamber 110 , thereby atomizing the liquid in the first atomizing chamber 110 .

[0037] In some embodiments, there are multiple first gas delivery holes 140 , and the multiple first gas delivery holes 140 surround the first atomization chamber 110 .

[0038] In this embodiment, the plurality of first air delivery holes 140 simultaneously spray high-speed airflow along the circumferential direction, so that the liquid can be fully in contact with the high-speed airflow, thereby making the liquid atomization more efficient.

[0039] In some embodiments, the liquid inlet 120 is connected to one end of the first atomizing chamber 110 , the injection hole 130 is connected to the other end of the first atomizing chamber 110 , and the inner diameter of one end of the first atomizing chamber 110 close to the injection hole 130 is smaller.

[0040] In this embodiment, since the inner diameter of the end of the first atomizing chamber 110 close to the injection hole 130 is smaller, the liquid flow velocity close to the injection hole 130 can be increased, so that the fluid discharged from the injection hole 130 has a faster flow rate.

[0041] In some embodiments, the first gas delivery hole 140 is connected to an end of the atomization chamber close to the injection hole 130 .

[0042] In this embodiment, the liquid flow velocity at the end of the atomization chamber close to the injection hole 130 is faster, and the space available for fluid flow is smaller. The faster the liquid flow velocity, the more intense the collision with the high-speed airflow, making the liquid atomization more complete.

[0043] In addition, a cooling and humidifying device is provided, which includes a mixing box A and the above-mentioned gas-assisted atomizer, and the gas-assisted atomizer introduces air entrained with water mist into the mixing box A.

[0044] In some embodiments, the cooling and humidifying device includes a plurality of gas-assisted atomizers, and the plurality of gas-assisted atomizers introduce air entrained with water mist into the mixing box A simultaneously.

[0045] In this embodiment, multiple gas-assisted atomizers simultaneously introduce air carrying water mist into the mixing box A, which can make the concentration of the water mist mixed inside higher.

[0046] In order to better understand the present invention, the following Figure 1 to Figure 2 The technical solution of the utility model is described in detail:

[0047] Liquid is introduced into the first atomizing chamber 110 through the liquid inlet hole 120. Since the inner diameter of the end of the first atomizing chamber 110 close to the injection hole 130 is smaller, the liquid flow velocity close to the injection hole 130 can be increased. The first gas delivery hole 140 introduces a high-speed airflow into the first atomizing chamber 110, so that the liquid in the first atomizing chamber 110 is initially atomized by the high-speed airflow. The airflow carrying the liquid mist enters the second atomizing chamber 210 through the injection hole 130. The airflow ejected from the injection gap 230 is conical and surrounds the airflow carrying the liquid mist derived from the injection hole 130, so that the high-speed airflow and the liquid are fully in contact, and the high-speed airflow can be used to perform secondary atomization on the airflow carrying the liquid mist. By using the gas-assisted atomizer provided by the utility model, the liquid undergoes two atomization operations, which can avoid the problem of insufficient liquid atomization.

[0048] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
