Abstract
Description
Technical Field
[0001] This application relates to an air outlet assembly with a push-pull mechanism and a bladeless fan. Background Technology
[0002] Existing air outlet components are designed with hot and cold air channels that can be switched. However, the existing switching structure for hot and cold air channels is relatively complex, making it prone to jamming during switching and resulting in low transmission efficiency. Chinese patent CN120889763A discloses a bladeless fan capable of switching between hot and cold air. It uses a knob to rotate two transmission arms, causing two split-flow cylinders to move outward or inward synchronously, thus achieving hot and cold air switching. However, in this switching structure, the transmission between the knob and the transmission arms is prone to jamming, resulting in incomplete switching between hot and cold air channels and cross-flow of hot and cold air, severely reducing the user experience.

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be arbitrarily combined with each other.
[0035] like Figure 1-2As shown in Figures 7 and 11-12, this application proposes an air outlet assembly with a push-pull mechanism, including a connecting base 3 and a push-pull mechanism and a duct connector disposed on the connecting base 3. The connecting base 3 has a hot air channel and a cold air channel; the duct connector is movably disposed within the connecting base 3 to connect with either the hot air channel or the cold air channel. The push-pull mechanism is movably connected to the duct connector and can be pushed or pulled to connect the duct connector with either the hot air channel or the cold air channel, realizing the switching between the hot and cold air channels. In this application, the push-pull mechanism can be disposed at the upper end of the connecting base 3, making it convenient to push and pull and easier to operate. By pushing the push-pull mechanism, the air outlet assembly proposed in this application can freely switch the duct connector between the hot air channel and the cold air channel, realizing either a hot or cold air operation mode. The structure is simpler, more practical, and easier to operate.
[0036] like Figure 2 , 8 As shown in Figure -12, in some embodiments, the cold air duct may include a first air outlet duct and a second air outlet duct, which are symmetrically arranged on the left and right sides of the connecting seat 3, respectively. Correspondingly, the air duct connectors include a first air duct connector 312 and a second air duct connector 313, which are telescopically mounted within the connecting seat 3. The connecting seat 3 is provided with an air inlet duct 317. For example... Figure 13 As shown, one end of the first air duct connector 312 is provided with a first connecting port 3122, and one end of the second air duct connector 313 is provided with a second connecting port 3132. Figure 11 As shown, the first air duct connector 312 and the second air duct connector 313 can be joined together to seal the hot air passage. At this time, the first air duct connector 312 is connected to the first air outlet passage and to the air inlet passage 317 in the connecting seat 3; the second air duct connector 313 is connected to the second air outlet passage and to the air inlet passage in the connecting seat 3. Specifically, when the first air duct connector 312 and the second air duct connector 313 are joined, the first connecting wall 3121 at one end of the first air duct connector 312 fits against the second connecting wall 3131 at one end of the second air duct connector 313, the first connecting port 3122 is connected to the air inlet passage 317, and the first air duct connector 312 can be connected to the first air outlet passage to achieve the connection of the first air outlet passage; the second connecting port 3132 is connected to the air inlet passage 317, and the second air duct connector 313 can be connected to the second air outlet passage to achieve the connection of the second air outlet passage. It should be noted that the first air duct connector 312 and the second air duct connector 313 can simultaneously connect to both the first and second air outlet channels, enabling air outlet from both sides, which is convenient to operate. Figure 12As shown, the first air duct connector 312 and the second air duct connector 313 can be separated from each other so that the first air duct connector 312 can be sealed to the first air outlet duct, that is, the first connecting wall 3121 of the first air duct connector 312 is sealed to the first air outlet duct, restricting the connection between the first air outlet duct and the air inlet duct 317; at the same time, the second air duct connector 313 can be engaged with the second air outlet duct so that the second connecting wall 3131 of the second air duct connector 313 is sealed to the second air outlet duct, thereby restricting the connection between the second air outlet duct and the air inlet duct 317. At this time, the hot air duct is directly connected to the air inlet duct 317, realizing hot air outlet.
[0037] like Figure 2-4 As shown, in some embodiments, the push-pull mechanism may include a push-pull assembly and a push rod 37. The push-pull assembly is reciprocally mounted on the connecting seat 3, making operation relatively simple. The push rod 37 is rotatably mounted on the push-pull assembly and is rotatably connected to the first air duct connector 312 and the second air duct connector 313, respectively, so as to drive the first air duct connector 312 and the second air duct connector 313 to engage, or simultaneously drive the first air duct connector 312 to seal with the first air outlet channel and the second air duct connector 313 to seal with the second air outlet channel. Specifically, as shown... Figure 15 As shown, push rod 37 includes a first push rod 371 and a second push rod 372, which are symmetrically arranged on the push-pull assembly. One end of the first push rod 371 is rotatably connected to the push-pull assembly through a second hinge hole 3712, and the other end of the first push rod 371 is rotatably connected to the connecting post 320 of the first air duct connector 312 through a first hinge hole 3711, so as to drive the first air duct connector 312 to reciprocate. One end of the second push rod 372 is rotatably connected to the push-pull assembly through a fourth hinge hole 3722, and the other end of the second push rod 372 is rotatably connected to the connecting post 320 of the second air duct connector 313 through a third hinge hole 3721, so as to drive the second air duct connector 313 to reciprocate. By adopting the above scheme, by designing two push rods to drive their respective air duct connectors to reciprocate, the switching of hot air channel and cold air channel is realized.
[0038] like Figure 2-4 As shown, in some embodiments, the push-pull mechanism further includes a torsion spring 38. The torsion spring 38 is disposed on the push-pull assembly and is movably connected to the first air duct connector 312 and the second air duct connector 313, respectively. Specifically, in its natural state, the torsion spring 38 can drive the first air duct connector 312 and the second air duct connector 313 to open at a preset angle. This facilitates pushing the push-pull assembly, causing the first push rod 371 and the second push rod 372 to simultaneously open the first air duct connector 312 and the second air duct connector 313 within the slide groove 323, thereby sealing the first and second air outlet channels respectively. Specifically, as... Figure 16 As shown, the torsion spring 38 includes a first torsion spring wall 382 and a second torsion spring wall 384. A torsion spring sleeve 381 is provided between the first torsion spring wall 382 and the second torsion spring wall 384. The torsion spring sleeve 381 is sleeved on the push-pull assembly. One end of the first torsion spring wall 382 is rotatably connected to the connecting post 320 of the first air duct connector 312 through the first connecting hole 383. One end of the second torsion spring wall 384 is rotatably connected to the connecting post 320 of the second air duct connector 313 through the second connecting hole 385. This allows the first air duct connector 312 and the second air duct connector 313 to be opened naturally, facilitating operation.
[0039] like Figure 2-4 As shown, in some embodiments, the push-pull assembly may include a push-pull button 35, a push-button bracket 36, and a slider 39. The slider 39 is slidably disposed within the connecting seat 3 to support the sliding of the push-pull button 35 and the push-button bracket 36. The push-button bracket 36 is disposed on the slider 39. The push-pull button 35 is disposed on the push-button bracket 36 and protrudes from the outer wall of the connecting seat 3, allowing it to reciprocate on the outer wall of the connecting seat 3. A push rod 37 and a torsion spring 38 are respectively sleeved on the slider 39 to achieve rotational positioning. The push-button bracket 36 can be a cylindrical bracket. To further achieve balanced sliding, a track component 311 is also provided within the connecting seat 3, with a slide rail on the track component 311, allowing the push-button bracket 36 to reciprocate within the slide rail. By designing the track component 311 on the push-button bracket 36 and the slider 39 at the bottom of the push-button bracket 36, the push-pull button 35 and the push-button bracket 36 can be better supported for reciprocating movement on the connecting seat 3, resulting in more stable operation.
[0040] like Figure 2-4 , Figure 14As shown, in some embodiments, the connecting seat 3 is further provided with a limiting member 310, which is used to clamp the push key bracket 36, thereby positioning the pushing position of the push key bracket 36. Specifically, the limiting member 310 includes a first limiting block 3111 and a second limiting block 3112, which are preferably elastic blocks. Springs 3115 are respectively provided on the outer side walls of the first limiting block 3111 and the second limiting block 3112 opposite to each other, so as to support the clamping of the first limiting block 3111 and the second limiting block 3112. A clamping channel is provided between the first limiting block 3111 and the second limiting block 3112, and a first limiting point 3113 is provided at one end of the clamping channel; a second limiting point 3114 is provided at the other end of the clamping channel; the push key bracket 36 can reciprocate within the clamping channel and can be clamped within the first limiting point 3113 and the second limiting point 3114. The first limit point 3113 and the second limit point 3114 represent the two states of cold air and hot air, respectively. This avoids incomplete switching and solves the problems of air leakage and crossflow in the air duct of the connector 3. For details, refer to... Figure 10 As shown, when the push-key bracket 36 is clamped at the first limit position 3113, the first push rod 371 and the second push rod 372 retract, at which point the first air duct connector 312 and the second air duct connector 313 engage. (Reference) Figure 9 As shown, when the push key bracket 36 is clamped at the second limit position 3114, the first push rod 371 and the second push rod 372 are mutually supported. At this time, the first air duct connector 312 is sealed to the first air outlet channel, and the second air duct connector 313 is sealed to the second air outlet channel.
[0041] like Figure 2-4 As shown, in some embodiments, the connecting seat 3 includes a duct housing, which comprises an upper duct housing 33 and a lower duct housing 34, which are joined together. Specifically, the first duct connector 312 and the second duct connector 313 are symmetrically arranged on both sides of the duct housing. Figure 5-6 As shown, the first air duct connector 312 and the second air duct connector 313 are respectively movably mounted within the air duct housing via slide rails. Specifically, taking the structure of the first air duct connector 312 as an example, the lower end of the first air duct connector 312 engages with the air duct housing via the first slide rail 321, and the upper end of the first air duct connector 312 engages with the air duct housing via the second slide rail 322, thereby enabling stable reciprocating movement within the air duct housing. Furthermore, the push-pull assembly of this application, in conjunction with the push rod and torsion spring, only requires a groove 323 on the air duct housing, and the connecting posts 320 on the first air duct connector 312 and the second air duct connector 313 are respectively movably mounted within the groove 323 and connected to the push-pull mechanism to achieve retraction and expansion.
[0042] like Figure 5 , 7 As shown in Figures 11-12, in some embodiments, the connecting base 3 is provided with a hot air outlet 319, which is connected to a hot air channel. A heating component is provided within the hot air channel, comprising a heating element support 314, a heating element 315, and a heating element front cover 316, with the front cover 316 positioned at the hot air outlet 319. The heating element 315 is mounted on the heating element support 314 and can be a PTC heating element. The connecting base 3 also provides an air inlet channel 317, one end of which is connected to a hot air channel or a cold air channel, and the other end of which is connected to an external air duct of the connecting base 3, thereby enabling air intake.
[0043] like Figure 1-2 As shown, in some embodiments, the air outlet assembly further includes an air outlet frame 4, which has an air outlet frame support 411. The air outlet frame 4 is an arc-shaped air outlet frame with multiple cold air outlets 43. Specifically, the air outlet frame support 411 has a flow channel inside; one end of the air outlet frame support 411 is connected to the air outlet frame 4, and its flow channel communicates with the cold air outlets 43 through the connecting channel inside the air outlet frame 4. The other end of the air outlet frame support 411 is connected to the air duct housing inside the connecting seat 3, and its flow channel communicates with the cold air channel. Preferably, the air outlet frame 4 includes a first air outlet frame 41 and a second air outlet frame 42, which are symmetrically arranged on the left and right sides of the connecting seat 3 to achieve circumferential air outlet.
[0044] like Figure 1 As shown, this application also proposes a bladeless fan, including a base assembly 1, a column assembly 2, and an air outlet assembly. The column assembly 2 is disposed on the base assembly 1, and the air outlet assembly is disposed on the column assembly 2, and the air outlet assembly is the aforementioned air outlet assembly. Specifically, the base assembly 1 contains a fan, and the column assembly 2 contains a transmission air duct. The connecting seat 3 of the air outlet assembly is disposed on the column assembly 2, and the other end of the air inlet channel 317 is connected to the transmission air duct in the column assembly 2.
