[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-6As shown, the utility model provides an exhaust structure for a mixer, comprising a lower cover shell 10 , an upper cover shell 11 , an isolation plate 12 and a motor assembly 13 .

[0024] The upper cover shell 11 is disposed on the lower cover shell 10 , wherein a receiving cavity is formed in the upper cover shell 11 and the lower cover shell 10 , wherein the motor assembly 13 is disposed in the receiving cavity through a motor bracket.

[0025] The isolation plate 12 is arranged in the receiving cavity to divide the receiving cavity into a first receiving cavity 121 and a second receiving cavity 122 that are not connected, wherein the second receiving cavity 122 is above the first receiving cavity 121, and a flow hole 120 is arranged in the isolation plate 12 to connect the first receiving cavity 121 and the second receiving cavity 122.

[0026] Preferably, the bottom of the motor assembly 13 corresponds to the circulation hole 120 , so that the wind flowing in from the circulation hole 120 blows into the motor assembly 13 .

[0027] In this embodiment, the side wall of the lower cover shell 10 is provided with a first air inlet 101 connected to the first containment cavity 121. Furthermore, the side wall of the upper cover shell 11 is provided with an air outlet 111 connected to the second containment cavity 122, so that the outside wind flows from the first air inlet 101 to the first containment cavity 121, and then flows into the second containment cavity 122 through the circulation hole 120 to dissipate the heat of the motor assembly 13, and then the wind after the heat is dissipated in the second containment cavity 122 is discharged from the air outlet 111.

[0028] Preferably, a first baffle corresponding to the first air inlet 101 is provided in the first containing cavity 121, so that the wind entering from the first air inlet 101 is blocked by the first baffle, and a second baffle corresponding to the air outlet 111 is provided in the second containing cavity 122, so that the wind in the second containing cavity 122 will not be directly discharged from the air outlet 111, but will be blocked by the second baffle, thereby further guiding the airflow, buffering and changing the direction of the airflow to be discharged, and reducing the noise when the gas flows out.

[0029] In this embodiment, the first baffle includes a first sub-baffle 141 , a second sub-baffle 142 and a third sub-baffle 143 , wherein the second sub-baffle 142 and the third sub-baffle 143 are respectively vertically disposed at two ends of the first sub-baffle 141 .

[0030] Preferably, the first baffle plate 141 and the side wall of the lower cover outer shell 10 form a first air duct 1401, the second baffle plate 142 and the outer wall of the lower cover outer shell 10 form a second air duct 1402, and the third baffle plate 143 and the outer wall of the lower cover outer shell 10 form a third air duct 1403, wherein the first air inlet 101 is connected to the first air duct 1401, and the first baffle plate 141, the second baffle plate 142 and the third baffle plate 143 form a first receiving space corresponding to the circulation hole 120, so that the wind enters the first air duct 1401 from the first air inlet 101, and then flows to the second air duct 1402 and the third air duct 1403, and finally flows into the first receiving space, and finally enters the circulation hole 120.

[0031] Furthermore, the bottom wall of the lower cover shell 10 is also provided with a second air inlet 102 connected to the first air duct 1401 , so that wind can also enter the first air duct 1401 through the second air inlet 102 .

[0032] Further, a filter screen is provided at the first air inlet 101 and / or the second air inlet 102. It should be understood that the filter screen can increase wind resistance to prevent water from entering, ensure dry noise in the air duct and increase the service life of the motor.

[0033] Preferably, the first baffle plate 141, the second baffle plate 142 and the third baffle plate 143 are all rectangular in shape, and the heights of the first baffle plate 141, the second baffle plate 142 and the third baffle plate 143 are the same, and the height of the first baffle plate 141 is equal to the depth of the first receiving cavity 121, so that the wind entering from the first air inlet 101 and the second air inlet 102 can only enter the second air duct 1402 and the third air duct 1403 along the first air duct 1401, and then enter the first receiving space from the second air duct 1402 and the third air duct 1403.

[0034] In this embodiment, the second baffle includes a fourth sub-baffle 151 , a fifth sub-baffle 152 and a sixth sub-baffle 153 , wherein the fifth sub-baffle 152 and the sixth sub-baffle 153 are respectively vertically disposed at two ends of the fourth sub-baffle 151 .

[0035] Preferably, the fourth baffle plate 151 and the side wall of the upper cover shell 11 form a fourth air duct 1501, the fifth baffle plate 152 and the outer wall of the upper cover shell 11 form a fifth air duct 1502, and the sixth baffle plate 153 and the outer wall of the upper cover shell 11 form a sixth air duct 1503, wherein the air outlet 111 is connected to the fourth air duct 1501, and the fourth baffle plate 151, the fifth baffle plate 152 and the sixth baffle plate 153 form a second receiving space for accommodating the motor assembly 13 and corresponding to the circulation hole 120, so that the wind input from the circulation hole 120 enters the second receiving space to dissipate the heat of the motor assembly 13, and the wind after heat dissipation enters the fifth air duct 1502 and the sixth air duct 1503 from the second receiving space, and finally enters the fourth air duct 1501 and is discharged from the air outlet 111.

[0036] That is to say, a second baffle is provided in the second receiving cavity 122 so as to buffer and change the direction of the airflow to be discharged, so that the airflow can be reversed multiple times inside, which can improve the heat dissipation effect on the one hand and reduce the noise when the gas flows out on the other hand.

[0037] Preferably, the fourth baffle plate 151, the fifth baffle plate 152 and the sixth baffle plate 153 are all rectangular in shape, and the heights of the fourth baffle plate 151, the fifth baffle plate 152 and the sixth baffle plate 153 are the same, and the height of the fourth baffle plate 151 is equal to the depth of the second receiving cavity 122, so that the wind entering from the circulation hole 120 can only enter the fifth air duct 1502 and the sixth air duct 1503 along the second receiving space, and then enter the fourth air duct 1501 from the fifth air duct 1502 and the sixth air duct 1503, and finally be discharged from the air outlet 111.

[0038] Furthermore, the bottom of the motor assembly 13 is provided with a fan blade 131 fixedly connected to the rotating shaft and located in the second receiving space, so that when the motor assembly 13 is working, the fan blade 131 is driven to rotate, so that the wind is sucked into the second receiving space, thereby causing the wind from the first air inlet 101 and the second air inlet 102 to be sucked in, reducing the internal motor temperature, and avoiding the motor from temporarily stopping working due to overheating protection. In other words, this embodiment fully utilizes the space inside the upper and lower cover shells by installing the fan blade 131 at the bottom of the motor and accelerating the airflow movement by the rotation of the fan blade 131, without adding additional structures, thereby improving the use efficiency.
