A spray tower fan

Abstract

A spray tower fan includes a housing with a receiving cavity inside. At least one impeller assembly is disposed within the receiving cavity. The housing also has an air inlet and an air outlet communicating with the receiving cavity. An atomizer is also disposed within the receiving cavity, and the atomizer has a mist outlet. An airflow regulating component is also disposed at the air outlet. The airflow regulating component includes a regulating housing disposed on the inner housing of the air outlet. An airflow convergence channel is disposed within the regulating housing, and the mist outlet is disposed within the airflow convergence channel. By providing the airflow convergence channel, the airflow carries the atomized water vapor and accelerates its discharge from the airflow convergence channel. This avoids the phenomenon where negative pressure exists in front of the atomizer due to obstruction, causing vortices to easily form on the outer side of the housing of the air outlet, thus causing water vapor to flow back to the housing and accumulate and drip.

Description

Technical Field

[0001] This utility model relates to the technical field of tower fans, and in particular to a spray tower fan. Background Technology

[0002] Existing tower fans often have atomizing devices at their air outlets. These devices atomize the water in the tank and mix it with the air blown out by the tower fan to create a mixed airflow that is then blown into the room, thus achieving a rapid cooling effect. However, due to the obstruction of the atomizing device, the airflow can easily form vortices on the outer casing of the air outlet. These vortices can cause the atomized water vapor to flow back onto the casing, accumulating and dripping. Users must clean the dripping water regularly, which is very inconvenient. Summary of the Invention

[0003] This utility model provides a spray tower fan that solves the problem that existing spray tower fans easily form vortices on the outer shell of the air outlet, causing water vapor to flow back to the shell and accumulate and drip.

[0004] A spray tower fan includes a housing with a receiving cavity inside. At least one impeller assembly is disposed within the receiving cavity. The housing also has an air inlet and an air outlet communicating with the receiving cavity. An atomizer is also disposed within the receiving cavity, and a mist outlet is provided on the atomizer. An airflow regulating component is also disposed at the air outlet. The airflow regulating component includes an regulating housing disposed on the inner housing of the air outlet.

The inner diameter of the air inlet is larger than the inner diameter of the air outlet, and the air inlet, air outlet, and mist outlet are coaxially arranged.

[0006] Furthermore, the wind turbine assembly includes a wind turbine and a drive motor connected to the wind turbine.

[0007] Furthermore, a positioning component is provided inside the airflow convergence channel. The outer diameter of the positioning component is smaller than the inner diameter of the airflow convergence channel. A connection port is provided through the middle of the positioning component.

[0008] Furthermore, there are two wind turbine assemblies. A mounting base is provided inside the storage cavity. The wind turbine assemblies are respectively arranged on the left and right sides of the mounting base. A partition is formed in the middle of the mounting base. The partition is used to isolate the wind turbine assemblies. The air outlet includes a first air outlet and a second air outlet arranged parallel to each other on the front side of the housing. The first air outlet and the second air outlet each correspond to one wind turbine assembly. The front side of the partition is installed on the back side of the housing between the first air outlet and the second air outlet. The air inlet includes a first air inlet arranged on the left side of the housing and a second air inlet arranged on the right side of the housing.

[0012] Furthermore, the adjusting component housing and the casing are integrally formed.

[0013] Furthermore, the positioning component and the adjusting component housing are integrally formed.

[0014] The beneficial effects of this utility model are: 1. By setting up an airflow convergence channel and placing the mist outlet inside the airflow convergence channel, the airflow will carry the atomized water vapor out of the airflow convergence channel at an accelerated speed.

The described embodiments are only some embodiments of this utility model. Other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of this utility model.

If the specific posture changes, the directional indicators will also change accordingly.

[0025] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "fixation," etc., shall be interpreted broadly. For example, they may refer to a fixed connection, a detachable connection, or an integral part; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; they may refer to the internal connection of two components or the interaction between two components. Unless otherwise expressly limited, those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0026] like Figure 1-6 As shown, a spray tower fan includes a housing 1, within which a receiving cavity 11 is provided. At least one impeller assembly 2 is disposed within the receiving cavity 11. The housing 1 also has an air inlet 12 and an air outlet 13 communicating with the receiving cavity 11. The impeller assembly 2 draws outside air into the receiving cavity 11 through the air inlet 12, accelerates it to form an airflow, and then discharges it through the air outlet 13. An atomizer 3 is also disposed within the receiving cavity 11, with a mist outlet 31 on the atomizer 3. An airflow regulating assembly 4 is also disposed at the air outlet 13, comprising an adjusting housing disposed within the housing 1 inside the air outlet 13. 41. An airflow convergence channel 411 is provided inside the housing 41 of the regulating component. The airflow convergence channel 411 connects the receiving cavity 11 with the external space, so that the airflow in the receiving cavity 11 forms a narrow tube effect when passing through, thereby accelerating the discharge. An air inlet 412 and an air outlet 413 are respectively formed on the housing 41 of the regulating component. The air inlet 412 is located inside the receiving cavity 11, and the air outlet 413 is located outside the receiving cavity 11. The inner diameter of the air inlet 412 is larger than the inner diameter of the air outlet 413. The mist outlet 31 is arranged inside the airflow convergence channel 411. The housing 41 of the regulating component and the housing 1 can be integrally formed.

[0027] When the airflow passes through the airflow convergence channel 411, it will be accelerated out of the airflow convergence channel 411 due to the narrow tube effect. The mist outlet 31 is set inside the airflow convergence channel 411. The airflow will carry the atomized water vapor out of the airflow convergence channel 411 together, forming a mixed gas in the external space away from the shell 1, achieving a rapid cooling effect. This avoids the phenomenon that the atomizing device is blocked, resulting in negative pressure on the front of the atomizing device, which makes it easy for vortices to form on the shell outside the air outlet, and thus causing water vapor to flow back to the shell 1.

[0028] The air inlet 412, air outlet 413 and mist outlet 31 are coaxially arranged.

[0029] like Figure 3 As shown, the wind turbine assembly 2 includes a wind turbine 21 and a drive motor 22 connected to the wind turbine 21. The drive motor 22 drives the wind turbine 21 to rotate and form an airflow.

[0030] The atomizer 3 is used to atomize water and discharge it from the mist outlet 31 to form a mixed gas with the airflow, thereby increasing indoor humidity and cooling. The atomizer 3 can be an existing ultrasonic atomizing device, mesh atomizing device, piezoelectric atomizing device, etc.

[0031] The adjusting component housing 41 and the housing 1 can be integrally formed.

[0032] like Figure 4 and 6 As shown, a positioning element 42 is provided inside the airflow convergence channel 411. The outer diameter of the positioning element 42 is smaller than the inner diameter of the airflow convergence channel 411. A connection port 421 is provided through the middle of the positioning element 42. The atomizer 3 is located on the back of the positioning element 42. The mist outlet 31 is connected to the connection port 421. The inner diameter of the connection port 421 is smaller than the inner diameter of the air outlet 413. The water mist discharged from the mist outlet 31 passes through the connection port 421 and enters the airflow in the airflow convergence channel 411. After passing through the gap between the positioning element 42 and the inner wall of the airflow convergence channel 411, the airflow reaches the front of the positioning element 42 and drives the water vapor to be discharged from the airflow convergence channel 411 at an accelerated speed, forming a mixed gas in the external space away from the housing 1. The positioning element 42 and the adjusting housing 41 can be integrally set.

[0033] like Figure 5 As shown, in other embodiments, the number of wind turbine assemblies 2 is two. To avoid mutual interference between the wind turbine assemblies 2 and to concentrate the blown airflow, a mounting base 14 is provided in the receiving cavity 11. The wind turbine assemblies 2 are respectively arranged on the left and right sides of the mounting base 14. A partition 141 is formed in the middle of the mounting base 14. The partition 141 is used to isolate the wind turbine assemblies 2. The air outlet 13 includes a first air outlet 131 and a second air outlet 132 arranged parallel to each other on the front side of the housing 1. The first air outlet 131 and the second air outlet 132 each correspond to one wind turbine assembly 2. The front side of the partition 141 is installed on the back side of the housing 1 between the first air outlet 131 and the second air outlet 132. The air inlet 12 includes a first air inlet 121 arranged on the left side of the housing 1 and a second air inlet 122 arranged on the right side of the housing 1. The first air inlet 121 and the second air inlet 122 each correspond to one wind turbine assembly 2.

[0034] like Figure 6 As shown, the partition 141 is provided with a mounting groove 1411, the position of the mounting groove 1411 corresponds to the positioning member 42, and the atomizer 3 is fixed in the mounting groove 1411.

[0035] like Figure 2 As shown, a water tank 15 is provided at the bottom of the back of the housing 1, and a water tank 5 is provided at the top of the water tank 15. A water pump 6 is also provided inside the housing 1. The water tank 5, the water pump 6 and the atomizer 3 are connected by a pipeline. When in use, the water pump 6 pumps the water in the water tank 5 to the atomizer 3, and the atomizer 3 atomizes it.

[0036] like Figure 2 and 6As shown, a first water return groove 422 is provided on the positioning member 42 on the outer periphery of the front of the connection port 421. A second water return groove 16 is provided on the front of the housing 1 in the vertical direction. The bottom of the first water return groove 422 is connected to the top of the second water return groove 16. A water return channel 1412 is provided in the partition 141. The bottom of the second water return groove 16 is connected to the water return channel 1412. A third water return groove 17 is provided on the back of the housing 1 in the vertical direction. The top of the third water return groove 17 is connected to the water return channel 1412, and its bottom is connected to the water tank 15. When condensation occurs around the mist outlet 31 due to factors such as temperature changes and airflow direction changes, water droplets can flow into the water tank 17 through the provided water return groove and water return channel.

[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
