[0011] In some embodiments of this utility model, the volute tongue is provided with a plurality of mounting holes, which are spaced apart from each other along the length of the volute tongue. Each accommodating part has a corresponding mounting hole at its bottom to connect the accommodating cavity and the side of the volute tongue away from the transmission wheel. The sweeping blade passes through the mounting hole and is connected to the transmission wheel.

[0012] In some embodiments of this utility model, the receiving portion includes a plurality of arc-shaped protrusions, which are spaced apart around the mounting hole to form the receiving portion having the receiving cavity, and the plurality of arc-shaped protrusions are configured to be spaced apart from each other along the same circumference.

[0013] In some embodiments of this utility model, the transmission wheel includes a transmission wheel body and a transmission rod connected to the transmission wheel body. The transmission rod is disposed at the end of the transmission wheel body away from the volute tongue. The transmission wheel body is disposed in the receiving cavity. The end of the transmission wheel body away from the volute tongue protrudes from the receiving portion so that the transmission rod is spaced apart from the receiving portion. The transmission rod is connected to the drive rod.

[0014] In some embodiments of this utility model, the sweeping blade includes a blade and a connecting shaft connected to one end of the blade. The connecting shaft is configured to switch between a first mode and a second mode under the action of an external force.

[0015] In some embodiments of this utility model, the connecting shaft includes a shaft body and a deformable portion connected to one end of the shaft body. The deformable portion includes a first sub-part and a second sub-part spaced apart from each other, and there is a preset distance between the first sub-part and the second sub-part. When the connecting shaft is in the first form, the first sub-part and the second sub-part maintain the preset distance. When the connecting shaft is in the second form, the first sub-part and the second sub-part are in contact with each other.

[0016] In some embodiments of this utility model, an indoor unit is also provided, which includes the above-described air-sweeping assembly.

[0017] In some embodiments of this utility model, an air conditioner is also provided, which includes the indoor unit described above.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0029] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0030] like Figures 1-5As shown, this utility model provides a sweeping assembly 20, including a volute 100, a drive rod 200, and multiple sweeping blades 300. Multiple transmission components 120 are rotatably connected to one side of the volute 100, and the multiple transmission components 120 are spaced apart from each other along the length of the volute 100. The drive rod 200 is located on the side of the volute 100 with the transmission components 120, and is connected to the multiple transmission components 120. The drive rod 200 is used to drive the transmission components 120 to rotate. The multiple sweeping blades 300 are located on the side of the volute 100 opposite to the transmission components 120, and each sweeping blade 300 passes through the volute 100 and is inserted into one transmission component 120.

[0031] The drive rod 200 is generally configured to reciprocate along the length of the volute tongue 100, thereby driving the transmission component 120 to reciprocate and rotate, which in turn causes the sweeping blades 300 to guide airflow.

[0032] The sweeping blade 300 passes through the volute tongue 100 and is plugged into the transmission component 120, meaning the sweeping blade 300 is detachably connected through the transmission component 120. The detachable connection between the sweeping blade 300 and the transmission component 120 also means that the sweeping blade 300 and the volute tongue 100 are detachably connected.

[0033] It is understood that the sweeping assembly 20 uses a rotatable transmission component 120 on the volute tongue 100 to drive the drive rod 200 to rotate the transmission component 120. The sweeping blades 300 are then connected to the transmission component 120, thereby enabling the drive rod 200 to drive the transmission component 120 to rotate, and the transmission component 120 to drive the sweeping blades 300 to rotate, thus achieving the sweeping function. At the same time, each sweeping blade 300 is connected to one transmission component 120. When a single sweeping blade 300 is damaged, only that single sweeping blade 300 needs to be disassembled and replaced, simplifying the maintenance process, improving maintenance efficiency, and reducing maintenance costs.

[0034] In some embodiments, the transmission component 120 is a swing rod. One end of the swing rod is inserted into the sweeping blade 300, and the other end is connected to the drive rod 200. The drive rod 200 drives the swing rod to rotate reciprocally, thereby driving the sweeping blade 300 to sweep. The swing rod is inserted into the sweeping blade 300 passing through the volute tongue 100 and connected to the drive rod 200, thus being limited between the volute tongue 100 and the drive rod 200. Specifically, one end of the swing rod has a bearing seat, which is inserted into and rotatably connected to the mounting hole 101 on the volute tongue 100, realizing the rotatable connection between the swing rod and the volute tongue 100. The bearing seat is provided with a connecting hole, and the sweeping blade 300 is inserted into the connecting hole, realizing the insertion connection between the sweeping blade 300 and the swing rod.

[0035] In some embodiments, only one drive rod 200 is provided on one side of the volute tongue 100, and the drive rod 200 is connected to all the transmission components 120 on the volute tongue 100.

[0036] In some embodiments, a plurality of drive rods 200 are provided on one side of the volute tongue 100, and each drive rod 200 is connected to N different transmission components 120.

[0037] In some embodiments, the transmission member 120 is a transmission wheel, which is plugged into the worm tongue 100.

[0038] That is, the transmission wheel is inserted into the worm tongue 100 and rotatably connected to the worm tongue 100. Thus, when a single transmission wheel is damaged, only the damaged transmission wheel can be replaced, instead of replacing the entire worm tongue 100. This reduces maintenance costs, simplifies maintenance, and improves maintenance efficiency.

[0039] In some embodiments, the volute tongue 100 is provided with a plurality of receiving portions 110, each receiving portion 110 having a receiving cavity, the plurality of receiving portions 110 being spaced apart from each other along the length direction of the volute tongue 100, and each drive wheel being rotatably disposed in a receiving cavity.

[0040] The drive wheel is inserted into the receiving part 110. Generally, in order to ensure the stability of the connection between the drive wheel and the receiving part 110, the drive wheel and the receiving cavity are interference fit.

[0041] The multiple accommodating parts 110 are spaced apart and equidistant from each other, thereby ensuring that the multiple sweeping blades 300 are also equidistant from each other, thus ensuring the uniformity of airflow.

[0042] In order to ensure that the transmission wheel can rotate smoothly, the transmission wheel generally adopts a disc-shaped structure, and the receiving cavity is also set as a corresponding circular receiving cavity.

[0043] In some embodiments, the volute tongue 100 is provided with a plurality of mounting holes 101, which are spaced apart from each other along the length direction of the volute tongue 100. Each accommodating part 110 has a corresponding mounting hole 101 at its bottom to connect the accommodating cavity and the side of the volute tongue 100 away from the drive wheel. The sweeping blade 300 passes through the mounting hole 101 and is connected to the drive wheel.

[0044] The mounting hole 101 provided on the volute tongue 100 facilitates the connection structure of the sweeping blade 300 to pass through the volute tongue 100 and connect with the drive wheel.

[0045] The spacing between adjacent mounting holes 101 is equal to the spacing between adjacent receiving portions 110.

[0046] In some embodiments, the receiving portion 110 includes a plurality of arcuate protrusions, which are spaced apart around the mounting hole 101 to form a receiving portion 110 having a receiving cavity, and the plurality of arcuate protrusions are configured to be spaced apart from each other along the same circumference.

[0047] Multiple arc-shaped protrusions are spaced apart from each other along the same circumference to form a receiving portion 110 with a circular cavity, so as to achieve a rotatable connection with the transmission wheel.

[0048] Multiple arc-shaped protrusions are spaced apart from each other around the mounting hole 101. The spacing facilitates the deformability of the receiving part 110, that is, it allows the transmission wheel to be inserted into the receiving part 110 by opening the receiving part 110, thereby achieving an interference fit between the transmission wheel and the receiving cavity; that is, it facilitates the insertion and separation of the transmission wheel and the receiving part 110.

[0049] In some embodiments, the transmission wheel includes a transmission wheel body 121 and a transmission rod 122 connected to the transmission wheel body 121. The transmission rod 122 is disposed at one end of the transmission wheel body 121 away from the volute tongue 100. The transmission wheel body 121 is disposed in the receiving cavity. The end of the transmission wheel body 121 away from the volute tongue 100 protrudes from the receiving portion 110 so that the transmission rod 122 and the receiving portion 110 are kept apart. The transmission rod 122 is connected to the drive rod 200.

[0050] The transmission wheel body 121 is generally a disc-shaped structure, which is rotatably disposed in the accommodating cavity.

[0051] The transmission wheel body 121 has one end protruding from the worm tongue 100 into the receiving part 110. That is, the transmission rod 122 is higher than the top of the receiving part 110, so that the transmission rod 122 will not interfere with the receiving part 110 (arc-shaped protrusion) when it rotates, and the transmission wheel can rotate smoothly under the drive of the drive rod 200.

[0052] The transmission rod 122 is generally L-shaped, and includes a first sub-rod and a second sub-rod connected vertically. The first sub-rod is connected between the transmission wheel body 121 and the second sub-rod. The first sub-rod is generally connected to the end of the transmission wheel body 121 and close to its edge, so that even a small reciprocating movement of the drive rod 200 can drive the transmission wheel body 121 to rotate a large angle, thereby enabling the sweeping blades 300 to have a large range of sweeping angles.

[0053] Generally, the first sub-rod and the drive rod 200 are parallel to each other, the second sub-rod and the drive rod 200 are perpendicular to each other, and the second sub-rod and the drive rod 200 are plugged into each other.

[0054] In some embodiments, the sweeping blade 300 includes a blade 310 and a connecting shaft 320 connected to one end of the blade 310. The connecting shaft 320 is configured to switch between a first state and a second state under the action of an external force. When the connecting shaft 320 is in the first state, the connecting shaft 320 is locked connected to the transmission member 120. When the connecting shaft 320 is in the second state, the connecting shaft 320 is separated from the transmission member 120.

[0055] The transmission component 120 is connected to the sweeping blade 300 by a shaft hole. The transmission component 120 has a connecting hole that is connected to the connecting shaft 320 of the sweeping blade 300. The connecting shaft 320 passes through the mounting hole 101 on the volute tongue 100 and connects to the connecting hole on the transmission component 120.

[0056] The connecting shaft 320 is locked to the transmission component 120, that is, the connecting shaft 320 is interference-fitted with the connecting hole. When the connecting shaft 320 is in the first state, the width of the connecting shaft 320 is greater than the width of the connecting hole. When the connecting shaft 320 is in the second state, the width of the connecting shaft 320 is less than the width of the connecting hole. The connecting shaft 320 can be easily pulled out of the connecting hole, thereby separating the connecting shaft 320 from the transmission component 120.

[0057] That is, by switching the connecting shaft 320 between different forms, the connecting hole of the connecting shaft 320 and the transmission component 120 are in different mating states, thereby switching the connection state between the connecting shaft 320 and the transmission component 120.

[0058] In some embodiments, the connecting shaft 320 includes a shaft body portion 321 and a deformable portion 322 connected to one end of the shaft body portion 321. The deformable portion 322 includes a first sub-part 3221 and a second sub-part 3222 spaced apart from each other, with a preset distance between the first sub-part 3221 and the second sub-part 3222. When the connecting shaft 320 is in a first state, the first sub-part 3221 and the second sub-part 3222 maintain the preset distance. When the connecting shaft 320 is in a second state, the first sub-part 3221 and the second sub-part 3222 are in contact with each other.

[0059] The connection between the connecting shaft 320 and the transmission wheel is essentially a connection between the deformable part 322 and the connecting hole of the transmission component 120.

[0060] When the first sub-part 3221 and the second sub-part 3222 maintain a preset distance, the width of the deformable part 322 is at its maximum, which is recorded as the first width. At this time, the deformable part 322 is locked to the transmission member 120, and the deformable part 322 is interference-fitted with the connection hole of the transmission member 120. That is, the connecting shaft 320 is in the first state and locked to the transmission member 120. When the first sub-part 3221 and the second sub-part 3222 are in contact with each other, the width of the deformable part 322 is at its minimum, which is recorded as the second width. It can be separated from the connection hole of the transmission member 120. That is, the connecting shaft 320 is in the second state and separated from the transmission wheel.

[0061] In order to ensure that the connecting shaft 320 can be locked and connected with the transmission member 120 in the first state, the width of the deformable part 322 in the first state is set to be greater than the width of the connecting hole of the transmission member 120; in order to ensure that the connecting shaft 320 can be separated from the transmission member 120 in the second state, the width of the deformable part 322 in the second state is set to be less than the width of the connecting hole of the transmission member 120.

[0062] The connecting shaft 320 and the blade 310 are generally made of plastic. The plastic connecting shaft 320 allows the deformable part 322 to have a certain degree of deformability.

[0063] In some embodiments, an indoor unit is also provided, which includes the above-described air-sweeping assembly 20. Since the air-sweeping assembly 20 includes at least some or all of the above embodiments, the indoor unit has at least the beneficial effects of some or all of the above embodiments, which will not be described in detail here.

[0064] The indoor unit includes a middle frame 10, and the air swing assembly 20 is disposed on the middle frame 10.

[0065] In some embodiments, an air conditioner is also provided, the refrigeration device including the above-described indoor unit. Since the indoor unit includes at least some or all of the embodiments of the above-described air-sweeping assembly 20, the air conditioner has at least the beneficial effects of some or all of the above-described embodiments, which will not be described in detail here.
