[0002] At present, the market is increasingly using handheld blenders, and the demand for waterproof grade, rotation speed, and high power is also getting higher and higher; the higher the power, the higher the temperature of the motor, so the market is in urgent need of blender products that can reduce the temperature of the motor, the temperature of the casing, and the high temperature inside the stirring rod.

[0003] The Chinese utility model patent with patent announcement number CN212574740U discloses a waterproof heat dissipation device for a food stirring rod, including a spacer assembly and a heat dissipation assembly. The spacer assembly wraps the motor assembly as a whole, the heat dissipation assembly is connected to the motor assembly, and the spacer assembly is installed between the motor assembly and the housing assembly of the stirring rod. The housing assembly is provided with an air inlet and an air outlet, and the two ends of the spacer assembly are provided with vents and air outlet holes. When the prior art is working, air can enter the vent along the air inlet, pass through the motor assembly, and be discharged from the air outlet to the air outlet; however, the air outlet of the prior art does not have an air guide structure used in conjunction with the motor assembly, and the exhaust efficiency is not high. It cannot quickly and effectively reduce the high temperature heat generated by the motor assembly when working, thereby affecting the stirring performance and service life.

[0004] Therefore, there is still room for improvement and development in the existing technology. Utility Model Content

[0005] In response to the problems in the prior art, the utility model provides a blender with fast air outlet and heat dissipation. An air guide cover corresponding to the fan assembly is provided in the air outlet, and a plurality of air outlet slots are distributed around the side wall of the air guide cover. The air exhaust efficiency is higher, and the high-temperature heat generated by the fan assembly when working can be quickly and effectively reduced, thereby ensuring the mixing performance of the blender and the working life of the blender.

[0006] In order to achieve the above purpose, the technical solution applied by the utility model is as follows:

[0007] A blender with fast air outlet and heat dissipation includes a main unit component and a stirring rod component, wherein the main unit component is drivingly connected to the stirring rod component, an air inlet is provided at the first end of the main unit component, an air outlet is provided at the second end of the main unit component, a heat dissipation air duct is formed between the air inlet and the air outlet, and a fan component for forming a heat dissipation airflow is provided in the heat dissipation air duct; an air guide cover is provided in the air outlet, the air guide cover is arranged corresponding to the fan component, and a plurality of air outlet slots are distributed around the side wall of the air guide cover. In this arrangement, by arranging an air guide cover arranged corresponding to the fan component in the air outlet, and distributing a plurality of air outlet slots around the side wall of the air guide cover, the exhaust efficiency is higher, and the high temperature heat generated by the fan component when working can be quickly and effectively reduced, thereby ensuring the mixing performance of the blender and the working life of the blender.

[0008] According to the above scheme, the fan assembly includes a motor, an impeller and a transmission rod, the impeller is fixed on the transmission rod, and the first end of the transmission rod is connected to the output end of the motor; the air guide cover is sleeved on the outside of the impeller, and the impeller is provided with a plurality of blades, and an air guide port is formed between two adjacent blades, and the air guide port is arranged corresponding to the air outlet slot. In this arrangement, when the motor is working, it drives the impeller to rotate at a high speed, and guides the airflow to the air outlet slot through the air guide port. In actual application, the impeller is a centrifugal impeller.

[0009] According to the above scheme, the air guide cover is a circular ring structure, and a plurality of air outlet slots are evenly distributed on the circumference of the side wall of the air guide cover in a circular shape and vertically; the impeller is a circular ring structure, and a plurality of blades are evenly distributed on the inner wall of the impeller in a circular shape and vertically. In this way, the air outlet slots and blades are both vertically arranged in a circular shape, and the whole machine is annularly exhausted, which is highly efficient. More specifically, it can increase the air flow speed when the impeller is working and increase the exhaust speed of the air outlet slot.

[0010] According to the above scheme, the inlet of the air outlet slot is larger than the outlet of the air outlet slot, and the inlet of the air outlet slot is an expanded inclined opening. This arrangement can increase the wind speed of the air outlet and prevent water droplets and agitated debris from entering; more specifically, the end of the air outlet slot close to the fan assembly is the inlet of the air outlet slot.

In this way, when the wind discharged from the air guide port hits the air outlet slot, it will quickly slide into the air outlet slot along the first oblique side of the inclined opening, and be guided to the air outlet end of the air outlet slot under the action of the second oblique side, thereby increasing the exhaust efficiency.

[0012] According to the above scheme, the angle between the blade and the center line of the impeller is 45-60 degrees; when the impeller rotates, the blade in the rotating direction is perpendicular to the inclined opening of the air outlet slot. With this arrangement, when the impeller rotates at a high speed, the blade blows the wind flow toward the outer circumference of the impeller, thereby guiding the wind to the air outlet slot of the air guide cover, and the wind flow directly enters the air outlet slot through the inclined opening and is discharged, thereby accelerating the air outlet efficiency.

[0013] According to the above solution, the distance between the inner wall of the air guide cover and the outer wall of the impeller is 1-4 mm. This arrangement ensures that the air volume has no space for circulation or circling when the impeller fans, and speeds up the air volume efficiency of the fan.

[0014] According to the above scheme, the thickness of the blade is 1.5-2.5mm. This arrangement can make the blades evenly distributed and reasonably utilize the space of the impeller.

This arrangement is convenient for operation, and the heat dissipation duct can also take away the heat generated by the circuit board during operation.

[0025] The technical solution of the utility model is described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figures 1 to 4 As shown, the utility model discloses a mixer with fast air outlet and heat dissipation, comprising a main unit assembly and a stirring rod assembly, wherein the main unit assembly is drivingly connected to the stirring rod assembly, an air inlet 2 is provided at the first end of the main unit assembly, an air outlet 6 is provided at the second end of the main unit assembly, a heat dissipation duct 8 is formed between the air inlet 2 and the air outlet 6, and a fan assembly for forming a heat dissipation airflow is provided in the heat dissipation duct 8; an air guide hood 7 is provided in the air outlet 6, the air guide hood 7 is arranged corresponding to the fan assembly, and a plurality of air outlet slots 71 are distributed around the side wall of the air guide hood 7. In this way, by providing an air guide hood 7 arranged corresponding to the fan assembly in the air outlet 6, and distributing a plurality of air outlet slots 71 around the side wall of the air guide hood 7, the exhaust efficiency is higher, and the high temperature heat generated by the fan assembly when working can be quickly and effectively reduced, thereby ensuring the mixing performance of the mixer and the working life of the mixer.

[0027] In this embodiment, the fan assembly includes a motor 4, an impeller 5 and a transmission rod 10, the impeller 5 is fixed on the transmission rod 10, and the first end of the transmission rod 10 is connected to the output end of the motor 4; the air guide cover 7 is sleeved on the outside of the impeller 5, and a plurality of blades 51 are provided on the impeller 5, and an air guide port 52 is formed between two adjacent blades 51, and the air guide port 52 is arranged corresponding to the air outlet slot 71. In this arrangement, when the motor 4 is working, it drives the impeller 5 to rotate at a high speed, and guides the air flow to the air outlet slot 71 through the air guide port 52. In actual application, the impeller 5 is a centrifugal impeller.

[0028] In this embodiment, the air guide cover 7 is a circular ring structure, and a plurality of air outlet slots 71 are evenly distributed vertically in a circular shape on the circumference of the side wall of the air guide cover 7; the impeller 5 is a circular ring structure, and a plurality of blades 51 are evenly distributed vertically in a circular shape on the inner wall of the impeller 5. In this arrangement, the air outlet slots 71 and the blades 51 are both vertically in a circular shape, and the whole machine is annularly exhausted, which is highly efficient. More specifically, the air flow speed of the impeller 5 when working and the exhaust speed of the air outlet slots 71 can be increased.

[0029] In this embodiment, the inlet of the air outlet slot 71 is larger than the outlet of the air outlet slot 71, and the inlet of the air outlet slot 71 is a flared inclined opening 72. This arrangement can increase the wind speed of the air outlet and prevent water droplets and agitated debris from entering; more specifically, one end of the air outlet slot 71 close to the fan assembly is the inlet of the air outlet slot 71.

[0031] In this embodiment, the angle between the blade 51 and the center line of the impeller 5 is 45-60 degrees; when the impeller 5 rotates, the blade 51 in the rotating direction is perpendicular to the inclined opening 72 of the air outlet slot 71. With this arrangement, when the impeller 5 rotates at a high speed, the blade 51 blows the wind flow toward the outer circumference of the impeller 5, thereby guiding the wind to the air outlet slot 71 of the air guide cover 7, and the wind flow directly enters the air outlet slot 71 through the inclined opening 72 and is discharged, thereby accelerating the air outlet efficiency.

[0032] In this embodiment, the distance between the inner wall of the air guide cover 7 and the outer wall of the impeller 5 is 1-4 mm. This arrangement makes it possible for the impeller 5 to have no space for the air volume to circulate or swirl when the impeller 5 is fanning, and speeds up the air volume efficiency of the fan.

In practical applications, 12 blades 51 are evenly distributed on the impeller 5, and the fanning effect is reasonable.

[0034] In this embodiment, the host assembly includes a body 1, a control panel 9 is provided on the body 1, a circuit board 3 is provided in a heat dissipation duct 8, and the control panel 9 is arranged corresponding to the circuit board 3. Such an arrangement is convenient for operation, and the heat dissipation duct 8 can also take away the heat generated by the circuit board 3 during operation. In actual applications, the circuit board 3 is electrically connected to the fan assembly.

[0035] In this embodiment, the stirring rod assembly includes a blade shaft 13, a stirring head 14, a stirring blade 15 and a body connector 18, wherein the stirring head 14 is fixedly connected to the body connector 18, and the body connector 18 is connected to the main assembly, the first end of the blade shaft 13 is fixedly connected to the stirring blade 15, the second end of the blade shaft 13 passes through the stirring head 14 and is located in the body connector 18, and a bearing assembly 16 is provided between the outer wall of the blade shaft 13 and the inner wall of the stirring head 14; the second end of the blade shaft 13 is coupled and connected to the transmission rod 10 of the fan assembly.

[0037] Working principle of this utility model:

[0038] During operation, the user operates the control panel 9 to start the motor 4, driving the blade shaft 13 and the stirring blade 15 to rotate at a high speed for stirring. At this time, the circuit board 3 and the motor 4 will generate a large amount of heat. While the motor 4 is working, it drives the impeller 5 to rotate to form a siphon effect, and air is sucked into the fuselage 1 from the air inlet 2 on the top of the fuselage 1, and a downward high-speed airflow is formed. The airflow passes through the circuit board 3 and the motor 4 to take away the high-temperature heat generated. Since the impeller 5 is a centrifugal impeller 5, the airflow will turn to the outer circumference of the impeller 5 after being acted upon by the blades 51 of the impeller 5, and blow tangentially to the air outlet slot 71 on the air guide cover 7. Since the two side walls of the air outlet slot 71 are inclined, and the direction of the inclined opening 72 of the air outlet slot 71 is nearly parallel to the wind direction blown out by the impeller 5, the wind blown out by the impeller 5 can be discharged out of the fuselage 1 more smoothly and quickly, so that the heat generated inside the fuselage 1 can be discharged out of the fuselage 1 more quickly, thereby extending the working time of the mixer and improving the service life of the product.
