Description

Air supply device Technical Field

[0001] The present invention relates to the technical field of air supply equipment, and in particular to an air supply device. Background Art

[0002] Figure 1 is a perspective view of a conventional air supply device. As shown in Figure 1, Chinese invention patent CN104204543 discloses an air supply device comprising a base and a housing. The housing 1' is equipped with an intake port 2', a high-pressure air generating unit, an outlet 3', an induced air intake port 4', an induced air mixing unit 5', and an induced air outlet 6'. In the induced air mixing unit 5', air drawn in from the multiple induced air intake ports 4' is mixed, and the induced air from the induced air mixing unit 5' is then blown out through the induced air outlet 6'. The induced air mixing unit 5' also includes a discharge electrode unit 7' (i.e., an ion generator) serving as a discharge unit. As a result, various ions and ozone generated by the discharge, which are effective for deodorization and sterilization, can be transported long distances along the induced air, effectively deodorizing and sterilizing large spaces. Furthermore, the housing 1' is spherical, so the air supply device can be used at any angle as long as the outlet 3' is not blocked. This means that the air supply device can effectively reach the airflow regardless of its location. However, when the angle of the housing 1' is adjusted so that the air outlet 3' is placed at an angle of tilted upward or straight upward, the user may accidentally splash liquid such as beverages onto the discharge electrode unit 7' through the induced air mixing portion 5'. The liquid entering the discharge electrode unit 7' may damage the function of the discharge electrode unit 7' and may fail to stably supply ions and ozone.

[0030] In addition, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0031] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0033] The air supply device of the embodiment of the present invention has the functions of air purification and ion release. In addition, the air supply device can not only play any one of the air purification and ion release functions, but also play both functions simultaneously.

[0034] The air supply device 100 includes a base 90 and a housing 10 provided on the base 90 .

[0035] The base 90 includes a chassis 91 and a turntable 92 that is rotatable relative to the chassis 91. The turntable 92 is mounted on the chassis 91. Both the chassis 91 and the turntable 92 are circular discs, with the lower edge of the turntable 92 snapping onto the outer edge of the upper edge of the chassis 91 for stability and reliability. The turntable 92 has an arc-shaped groove, into which the housing 10 is placed, allowing the housing 10 to rest securely on the base 90 and rotate with the turntable 92. The housing 10 houses a main control board that controls the high-pressure air generator 40 (described later) and a Type-C port connected to the main control board. The base 90 houses a base circuit board that controls the rotation of the chassis 91. A data cable extending from the base circuit board is plugged into the Type-C port, enabling communication between the main control board and the base circuit board. For example, the base circuit board activates the base 90's rotation function only when it receives a signal from the main control board indicating that the high-pressure air generator 40 (described later) is operating. This allows the air supply device 100 to rotate and oscillate under the influence of the base 90 only when the air supply is in the air supply state.

[0036] The casing 10 is provided with an inlet 101 , a high-pressure air generating unit 40 , an outlet 102 , a first air passage 103 , an induced air inlet 104 , an induced air mixing unit 80 , an induced air outlet 105 , and a second air passage 106 .

[0037] Here, the shell 10 is spherical, and more specifically, in the present embodiment, the shell 10 is approximately spherical. The so-called approximately spherical shape refers to a shape that appears to be a sphere at first glance. This expression takes into account the unevenness and the like generated on the surface of the shell 10 due to the blow-out port 102, etc., and the imaginary sphere forming the outline of the shell 10 is not a perfect sphere. That is, when the imaginary sphere is not a perfect sphere, the shell 10 is expressed as being approximately spherical. However, it should be noted that the shell 10 is not particularly limited to being approximately spherical. In other embodiments, the shape of the shell 10 may also be a polyhedron (for example, a regular polyhedron and a truncated polyhedron), a cylinder, a polygonal prism, etc.

[0038] The housing 10 comprises an outer shell and a filter cover, which is mounted on the outer shell via elastic clips. The filter cover is provided with multiple elongated openings for air to pass through, forming an inlet 101 for drawing air from outside the housing 10. A filter is located downstream of the filter cover to filter the air. This filter can be either a primary filter for large particles or a high-efficiency filter for fine particles such as PM2.5.

[0039] The high-pressure air generating unit 40 includes an impeller for generating high-pressure air and a motor for driving the impeller.

[0040] The blowout port 102 is an annular opening for blowing out high-pressure air. It should be noted that the annular shape is not limited to a circular ring, but can also be a ring formed by other shapes, for example, a polygonal ring, or a ring shape composed of curves.

[0041] The first air passage 103 is an air passage that guides high-pressure air from the impeller to the air outlet 102. The first air passage 103 is defined by the outer wall 11, the inner wall 12, and the through wall 13.

[0042] Multiple induced air intake ports 104 are provided in the housing and are arranged in a circular pattern. In this embodiment, referring to FIG2 , six induced air intake ports 104 are provided. Air is induced by the high-pressure air blown out of the blowout port 102 and drawn into the induced air intake ports 104. The air drawn into the induced air mixing unit 80 from the multiple induced air intake ports 104 is then mixed to form induced air.

[0043] The induced air blowing port 105 blows out the induced air in the induced air mixing portion 80. The induced air blowing port 105 is formed by being surrounded by the inner wall 12 constituting the inner ring of the blowing port 102.

[0044] Second air passage 106 connects induced air intake port 104, induced air mixing section 80, and induced air outlet 105. Second air passage 106 is defined by inner wall 12 and through-wall 13. Through-wall 13 extends from induced air intake port 104 to induced air mixing section 80. Through-wall 13 forms the perimeter wall of a through-hole, at which second air passage 106 intersects first air passage 103.

[0045] The suction port 101 is centered at a suction position that is farthest from the blowing center of the blowout port 102. Therefore, the suction port 101 is far away from the blowout port 102, preventing the high-pressure air blown out of the blowout port 102 from being sucked back into the suction port 101, and effectively sending the high-pressure air to a distant place.

[0046] According to this structure, the impeller is built into the housing 10 in a manner that is inaccessible from the outside of the air blower 100. Therefore, the user does not have to worry about being injured by contact with the impeller and can use the air blower 100 with confidence.

[0047] The air guided from the plurality of guided air intake ports 104 is mixed in the guided air mixing unit 80. The mixed guided air is then redirected to the guided air outlet 105 and is blown out from the guided air outlet 105.

[0048] A discharge electrode unit housing 30 is provided within the first air passage 103. The discharge electrode unit housing 30 includes a first space 302 surrounding the discharge electrode unit 20 and a second space 303 through which ions flow toward an ion outlet 301. The first space 302 and the second space 303 are connected. Various ions and ozone, which are effective for deodorization and sterilization, are generated by the discharge electrode unit 20 within the first space 302 through discharge. These ions and ozone are then transported from the first space 302 to the second space 303 and then blown out of the ion outlet 301 in the second space 303. After being blown out, they are transported over long distances through the outlet 102 in the direction of the high-pressure air flow, effectively deodorizing and sterilizing a large area. In this embodiment, the first space 302 also includes a muffler 70. The inner wall of the muffler 70 is provided with muffler cotton 71 to absorb the noise generated by the high-voltage discharge, thereby reducing the noise level during operation of the air supply device 100. When high-pressure air is blown from the intake port 101 to the outlet 102, a negative pressure is formed outside the ion external outlet 301, causing the ions and ozone discharged from the ion external outlet 301 to be drawn into the first air passage 103, where they mix with the high-pressure air and are blown out through the outlet 102. In other words, the ions and ozone are blown out of the outlet 102 along with the high-pressure air. Because the ion external outlet 301 is located at the end of the second space 303 near the outlet 102, i.e., the distance between the ion external outlet 301 and the outlet 102 is relatively close, the ions and ozone can be blown out of the outlet 102 more easily. Since the discharge electrode unit case 30 is disposed within the first air passage 103, which is in turn disposed within the housing 10, the risk of liquid contacting the discharge electrode unit 20 can be reduced to a certain extent by the obstruction provided by the housing 10. In addition, the discharge electrode unit 20 is surrounded by the first space 302, and the first space 302 is only connected to the second space 303, forming a similar sealed space. Therefore, the risk of liquid contacting the discharge electrode unit 20 can be further suppressed to a certain extent through the barrier of the discharge electrode unit box 30 itself.

[0049] Furthermore, the ion external exhaust port 301 is staggered from the blowout port 102 and is located closer to the side wall of the housing 10 than the blowout port 102. Thus, when liquid enters the housing 10 through the blowout port 102, it is difficult for the liquid to enter the discharge electrode unit case 30 through the ion external exhaust port 301.

[0050] According to one embodiment of the present application, as shown in Figure 6 , the plane where the ion external outlet 301 is located is perpendicular to the plane where the blowout port 102 is located. Specifically, a line L1 extending from the plane where the ion external outlet 301 is located toward the blowout port 102 is perpendicular to a line L2 extending from the plane where the blowout port 102 is located toward the ion external outlet 301. Because the plane where the ion external outlet 301 is located is perpendicular to the plane where the blowout port 102 is located, when liquid enters the housing 10 through the blowout port 102, it is more difficult for it to enter the discharge electrode unit case 30 through the perpendicular ion external outlet 301.

[0051] Because the housing 10 is roughly spherical, when the discharge electrode unit case 30 is placed within the first air passage 103, the second space 303 is configured to match the spherical shape of the housing 10, forming an arc-shaped curve from upstream to downstream within the first air passage 103, toward the inner circumference of the housing 10. As shown in FIG7A , when the housing 10 is positioned with the ion external discharge port 301 facing downward, liquid is unlikely to enter the ion external discharge port 301. Even if a small amount of liquid does enter the second space 303 of the discharge electrode unit case 30 through the ion external discharge port 301, it will flow out of the discharge electrode unit case 30 along the arc-shaped second space 303 and will not flow upward into the first space 302, thus preventing damage to the discharge electrode unit 20. As shown in Figure 7B, a drain port 306 is provided on the downstream side of the ion internal discharge port 305. When the shell 10 is placed with the ion external discharge port 301 facing upward, even if a small amount of liquid enters the second space 303 of the discharge electrode unit box body 30 through the ion external discharge port 301, it can be discharged to the outside of the discharge electrode unit box body 30 through the drain port 306 before entering the first space 302.

[0052] A first baffle 50 is provided at one end of the ion external outlet 301 near the blowout port 102. The first baffle 50 covers at least a portion of the ion external outlet 301 to prevent liquid from entering the second space 303 through the ion external outlet 301. Specifically, the ion external outlet 301 can be configured as a circle, and the first baffle 50 can be configured as a semicircle, covering the portion of the ion external outlet 301 near the blowout port 102, further preventing liquid from entering the discharge electrode unit case 30 through the ion external outlet 301. In addition, a notch 304 is provided on the periphery of the ion external outlet 301 opposite the first baffle 50. The notch 304 communicates with the ion external outlet 301 and is configured to allow ions and ozone to flow into the first air path 103. The notch 304 allows more ions to flow out, thereby ensuring the outflow of ions.

[0053] A second baffle 60 is located at one end of the drain port 306, near the ion internal discharge port 305. The second baffle 60 extends away from the ion internal discharge port 305 and is inclined toward the inside of the second space 303. Located outside the ion internal discharge port 305, the second baffle 60 prevents liquid from entering the second space 303 from entering the first space 302 while still ensuring that ions can be discharged through the ion internal discharge port 305. It then directs the liquid out of the drain port 306, preventing damage to the discharge electrode unit 20 in the first space 302.

[0054] In addition, as the discharge electrode unit 20, an ozone generating electrode unit or an ion generating electrode unit to which a high voltage is applied may be used.

[0055] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0056] Furthermore, the use of ordinal numbers such as "first," "second," and "third" in the specification and claims to modify corresponding elements does not in itself imply or represent any ordinal number of the element, nor does it represent the order of one element relative to another, or the order in the manufacturing method. The use of such ordinal numbers is only used to clearly distinguish one element with a certain name from another element with the same name.
