Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, in particular to a human body device with a fan function. Background Art

[0002] In the prior art, there has been a precedent for the structural design of "applying the fan function to a human body device so that when a user uses the human body device, the user can enjoy the wind blown by the fan on it".

[0003] For example, an electric fan chair disclosed in the Chinese utility model patent CN202959602U includes chair legs, a backrest, armrests and a seat; the edges of the armrests and the backrest are integrally wound by a hollow tube, and a plurality of air outlet holes are formed in the tube wall of the hollow tube. A tube-type electric fan and a power plug are arranged under the seat, and the tube-type electric fan and the power plug are connected by a power cord. The tube-type electric fan blows air into the hollow tube body. Although this chair can realize the fan function, it has the following defects:

[0004] On the one hand, it blows air outwards by arranging a plurality of air outlet holes on the tube wall. The blown air is dispersed, not concentrated, not uniform, and cannot be blown far. The wind feeling felt by the human body is not obvious, and the user experience is poor.

[0005] On the other hand, it uses a common tube-type electric fan to blow air into the hollow tube body, and the wind pressure is insufficient. In actual use, it is difficult to effectively pump the external air flow to all parts of the hollow tube integrally wound. It is easy to have a phenomenon that the air volume is large in the part close to the tube-type electric fan, while the air volume is small or even zero in the part far from the tube-type electric fan, resulting in uneven blown air volume and small coverage area. Summary of the Utility Model

As a result, wherever there are strip-shaped narrow air outlet slits on the support member, an air flow with balanced and stable air volume can be ejected outward, thereby increasing the air outlet coverage area.

[0035] The present utility model will be further described in detail below with reference to the embodiments given in the drawings.

[0036] As Figures 1 to 11 shown, a human body device with a fan function provided by the present utility model includes a device body 1 and a fan device 2. The fan device 2 includes an air inlet 21, an air outlet 22, and an impeller 23 and a motor 24 disposed inside the fan device 2. The motor 24 drives the impeller 23 to suck external air from the air inlet 21 and generate an air flow through the air outlet 22.

[0037] The device body 1 can carry a human body, that is, it can be used for a human body to sit, lie, recline, stand, ride, etc. The device body 1 includes a support member 11. The support member 11 can be a support component on the device body 1 that participates in carrying the human body, or a support component on the device body 1 that does not participate in carrying the human body.

[0038] An internal passage 111 for receiving the air flow passing through the air outlet 22 is provided inside the support member 11. The front end of the support member 11 has at least one strip-shaped air outlet slit 112 disposed along the extending direction of the support member 11. A plurality of spaced ribs 1121 are provided in the strip-shaped air outlet slit 112. The plurality of spaced ribs 1121 divide the strip-shaped air outlet slit 112 into several exhaust ports 1122. The air flow received by the internal passage 111 is discharged from each exhaust port 1122 and blown towards the human body carried on the device body 1.

[0039] In a preferred example of the present utility model, at least one strip-shaped air outlet slit 112 is opened at the front end of the support member 11 at an inward inclination angle or an outward inclination angle or an angle orthogonal to the plumb plane. Here, "inward inclination" means inclined towards the inside of the support member 11, "outward inclination" means inclined towards the outside of the support member 11, and "plumb plane" means a plane perpendicular to the horizontal plane. Specifically, when the support member 11 is located at the outer side position of the human body's wind-receiving part, the strip-shaped air outlet slit 112 is preferably opened at the front end of the support member 11 at an inward inclination angle. When the support member 11 is located at the inner position of the human body's wind-receiving part, the strip-shaped air outlet slit 112 is preferably opened at the front end of the support member 11 at an outward inclination angle. When the support member 11 is facing the human body's wind-receiving part, the strip-shaped air outlet slit 112 is preferably opened at the front end of the support member 11 at an angle orthogonal to the plumb plane. In this way, it can ensure that the human body is effectively exposed to the wind.

[0040] In a preferred example of the present utility model, the inner side of the front end of the support member 11 has an inner inclined surface 110, and at least one strip-shaped air outlet slit 112 is vertically opened on the inner inclined surface 110, which can facilitate the inward inclination design of the strip-shaped air outlet slit 112.

[0041] In a preferred example of the present utility model, the impeller 23 is a mixed-flow impeller having a generally conical or truncated conical shape. The small end of the impeller 23 is arranged close to the air inlet 21 side, and the large end is arranged close to the air outlet 22 side. The motor 24 is located downstream of the impeller 23 and is coaxially connected to the impeller 23. The rotational speed of the motor 24 is 4000 - 8000 revolutions per minute. The width of the strip-shaped air outlet narrow slit 112 is 1.0 - 8.0 mm, preferably 2 - 5 mm. In this structure, the impeller 23 rotates at a high speed driven by the motor 24, can generate a relatively high air pressure to suck in external air, and form a strong high-speed flow to be fully and effectively delivered to various parts of the support member 11, and finally is ejected outward at a high speed through the strip-shaped air outlet narrow slit 112 arranged along the extending direction of the support member 11. In this way, not only can the balance and stability of the air volume be ensured, but also the effective air supply distance and air supply area are improved.

[0042] In a preferred example of the present utility model, the support member 11 includes two side segments 11a arranged at intervals left and right and extending in the up and down direction. The front ends of the two side segments 11a respectively have a first strip-shaped air outlet narrow slit 112a arranged along their respective extending directions, and the first strip-shaped air outlet narrow slit 112a is opened at the front ends of the two side segments 11a at a first inward inclination angle. The first inward inclination angle is 10 - 45 degrees, so that the air flow can be ejected toward the front inside of the two side segments 11a, and thus the purpose of effectively supplying air to the human body can be achieved.

[0043] In another preferred example of the present utility model, the support member 11 further includes an upper segment 11b connected to the upper ends of the two side segments 11a and extending in the left and right direction. The internal passage 111 penetrates through the two side segments 11a and the upper segment 11b. The front end of the upper segment 11b has a second strip-shaped air outlet narrow slit 112b arranged along its extending direction, and the second strip-shaped air outlet narrow slit 112b is opened at the front end of the upper segment 11b at a second inward inclination angle. The second inward inclination angle is 5 - 30 degrees, so that the air flow can be ejected toward the front inside of the upper segment 11b, and thus the purpose of effectively supplying air to the human body can be achieved.

[0044] In still another preferred example of the present utility model, the support member 11 further includes two lower segments 11c respectively extending inward from the lower ends of the two side segments 11a. The internal passage 111 also penetrates through the two lower segments 11c, and the front ends of the two lower segments 11c respectively have a third strip-shaped air outlet narrow slit 112c arranged along their respective extending directions, and the third strip-shaped air outlet narrow slit 112c is opened at the front ends of the two lower segments 11c at an angle orthogonal to the plumb plane, so that the air flow can be ejected toward the front of the two lower segments 11c, and thus the purpose of effectively supplying air to the human body can be achieved.

[0045] In a preferred example of the present utility model, an air flow receiving cover 12 is connected between one ends of the two lower segments 11c away from the two side segments 11a. The air flow receiving cover 12 is connected to the air outlet 22, and is used for receiving the air flow passing through the air outlet 22 and dividing it into two parts to send into the two lower segments 11c. At the same time, since the internal channel 111 penetrates through the two lower segments 11c, the two side segments 11a and the upper segment 11b, therefore, the air flow sent into the two lower segments 11c will enter the two side segments 11a and the upper segment 11b along the internal channel.

[0046] In a preferred example of the present utility model, the fan device 2 further includes a cylindrical outer shell 25, an air inlet plate 26, an air outlet plate 27, an impeller housing 28 and a motor upper cover 291.

The impeller housing 28 is installed inside the cylindrical outer shell 25, and the impeller 23 is arranged inside the impeller housing 28. The air outlet plate 27 is detachably installed at the top opening 252 of the cylindrical outer shell 25. A motor lower cover 292 that sinks into the cylindrical outer shell 25 and extends into the inside of the impeller 23 is formed in the center of the air outlet plate 27. The motor upper cover 291 is fixedly connected to the side of the motor lower cover 292 facing away from the impeller 23. The motor 24 is placed in the cavity formed between the motor upper cover 291 and the motor lower cover 292, and the drive shaft of the motor 24 passes through the motor lower cover 292 and is connected to the impeller 23. A plurality of air outlet holes 271 surrounding the motor lower cover 292 are further provided on the air outlet plate 27, and the plurality of air outlet holes 271 form the air outlet 22. The inlet end of the air flow receiving cover 12 covers the air outlet plate 27 and is fixed to the cylindrical outer shell 25 by screws.
