[0033] The embodiment relates to a light sound mixer with heat dissipation and noise reduction. Figures 1-9 , comprising a main machine 10 and a cup body 20 which can be detachably connected, the cup body 20 is located above the main machine 10, the main machine 10 and the cup body 20 are formed with a first chamber 101 and a second chamber 201 respectively, a motor 30 and a heat dissipation blade 301 connected with an output shaft of the motor 30 are arranged in the second chamber 201, the light sound mixer is also provided with a first noise reduction air duct and a second noise reduction air duct which respectively communicate with the first chamber 101 and the second chamber 201, the air outlet surface of the heat dissipation blade 301 faces the second noise reduction air duct, the first noise reduction air duct is used for guiding the cold air outside to the motor 30 in the second chamber 201 from the first chamber 101, so that the motor 30 is heat dissipated, and the second noise reduction air duct is used for guiding the hot air generated by the motor 30 in the second chamber 201 to the first chamber 101 and then discharging.

[0034] It should be noted that the motor 30 in the embodiment is a double-shaft motor 30, one of the output shafts is connected to the knife assembly structure of the mixer upward, and the other output shaft is connected to the heat dissipation blade 301 downward, so that the heat dissipation can be carried out synchronously during stirring when the food materials are stirred.

[0035] When working, the motor 30 drives the heat dissipation blade 301 to rotate, so that the negative pressure is generated in the first noise reduction air duct, thereby the cold air outside is sucked into the first chamber 101 and then enters the motor 30 through the first noise reduction air duct and heat dissipates the motor 30, at this time, the heat dissipation blade 301 blows the hot air generated by the motor 30 into the second noise reduction air duct, and the hot air enters the first chamber 101 under the guidance of the second noise reduction air duct and then is discharged, so that the heat dissipation function of the motor 30 is realized, meanwhile, the noise generated by the motor 30 is eliminated in the first noise reduction air duct and the second noise reduction air duct, and it is difficult to spread to the outside, so that the effect of noise reduction is realized, so that the mixer has better heat dissipation and noise reduction performance, and the user experience is improved.

[0036] Further, referring to Figure 1 and Figure 3 , the host 10 includes a host shell 11 and a bottom cover 12 arranged at the bottom of the host shell 11, the cup body 20 includes a cup body 21 and a cup seat 22 arranged at the bottom of the cup body 21, the motor 30 is located in the cup seat 22, and the cup seat 22 is further provided with a fan cover 23 for accommodating the motor 30. The host shell 11 and the bottom cover 12 cooperate to form the first chamber 101, and the inner wall of the cup seat 22 and the fan cover 23 form the second chamber 201.

[0037] The host shell 11 and the bottom cover 12 cooperate to form the first chamber 101, and the inner wall of the cup seat 22 and the fan cover 23 form the second chamber 201, so that when the motor 30 is working, the cold air from the outside is sucked into the first chamber 101 and flows upward to the second chamber 201, then enters the fan cover 23 to cool the motor 30, and then the hot air generated by the fan is blown to the first chamber 101 below and discharged, forming a complete air circulation path, thereby realizing stable cooling of the motor 30.

[0038] Further, the first noise reduction air duct includes a bottom cover air inlet 41 opened on the bottom cover 12, a host shell air inlet 42 opened on the host shell 11, a cup seat air inlet 43 opened on the bottom of the cup seat 22, and a fan cover air inlet 44 opened on the upper part of the fan cover 23. The bottom cover air inlet 41 is used to communicate the first chamber 101 with the outside atmosphere, so that the cold air from the outside can enter the first chamber 101, and the host shell air inlet 42 and the cup seat air inlet 43 are arranged opposite to each other, so that the air in the first chamber 101 can quickly enter the second chamber 201 through the cup seat air inlet 43 after passing through the host shell air inlet 42.

[0039] It can be understood that by adopting the above arrangement, when working, the cold air from the outside enters the fan cover 23 to cool the motor 30 after passing through the bottom cover air inlet 41, the host shell air inlet 42, the cup seat air inlet 43 and the fan cover air inlet 44 in turn. The air flow path is clear, the air pressure in the first chamber 101 and the second chamber 201 is stable, and the situation that the air flows randomly or the airflow in the first chamber 101 and the second chamber 201 is turbulent to affect the cooling efficiency of the motor 30 is avoided.

[0040] Further, referring to Fig Figure 4 , Figure 5 and Figure 6The number of the bottom cover air inlets 41, the main machine shell air inlets 42, the cup seat air inlets 43 and the air cover air inlets 44 is several, and the several bottom cover air inlets 41, the main machine shell air inlets 42, the cup seat air inlets 43 and the air cover air inlets 44 are evenly distributed on the side wall of the bottom cover 12, the outer side edge of the bottom of the main machine shell 11, the outer side edge of the bottom of the cup seat 22 and the side wall of the air cover 23, and the main machine shell air inlets 42, the cup seat air inlets 43 and the air cover air inlets 44 are located on the same vertical straight line.

[0041] The setting of the several bottom cover air inlets 41, the several main machine shell air inlets 42, the several cup seat air inlets 43 and the several air cover air inlets 44 enables the air to pass more smoothly, and the bottom cover air inlets 41, the main machine shell air inlets 42, the cup seat air inlets 43 and the air cover air inlets 44 are respectively arranged on the outer side of the bottom cover 12, the outer side of the main machine shell 11, the outer side of the cup seat 22 and the outer side of the air cover 23 and located on the same vertical straight line, so that when the motor 30 drives the heat dissipation blades 301 to work, the negative pressure generated by the heat dissipation blades 301 can make the cold air outside quickly enter the air cover 23 through the bottom cover air inlets 41, the main machine shell air inlets 42, the cup seat air inlets 43 and the air cover air inlets 44, thereby improving the heat dissipation efficiency.

[0042] In addition, referring to Figure 7 and Figure 8 , it should be noted that in the utility model, the air cover air inlets 44 are two different shape slot holes, one is a round hole air inlet 441, and the other is a slot air inlet 442, and the round hole air inlet 441 and the slot air inlet 442 are small size slot holes, so as to prevent the noise generated by the motor 30 from being transmitted from the round hole air inlet 441 and the slot air inlet 442, thereby achieving the effect of noise reduction.

[0043] Further, the second noise reduction air duct comprises the air cover air outlet 51 arranged at the bottom of the air cover 23, the cup seat air outlet 52 arranged at the bottom of the cup seat 22, the main machine shell air outlet 53 arranged at the bottom of the main machine shell 11 and the bottom cover air outlet 54 arranged on the bottom cover 12, and the air outlet surface of the heat dissipation blades 301 faces the air cover air outlet 51, so that the hot air generated when the motor 30 works can be quickly blown into the first cavity 101 through the air cover air outlet 51, the cup seat air outlet 52 and the main machine shell air outlet 53.

[0044] It can be understood that the second noise reduction channel is formed by the cooperation of the air cover air outlet 51, the cup seat air outlet 52, the main machine shell air outlet 53 and the bottom cover air outlet 54, so that the heat generated by the motor 30 can be quickly discharged, and the inside of the air cover 23 can be kept at a lower temperature, thereby avoiding the damage of the motor 30 caused by the high temperature inside the air cover 23.

[0045] Further, referring to Figure 4 ,Figure 5 and Figure 6 The number of the air outlet of the shroud 51, the air outlet of the cup seat 52, the air outlet of the main shell 53 and the air outlet of the bottom cover 54 is several. The several air outlets of the shroud 51, the cup seat 52 and the bottom cover 54 are evenly distributed on the inner side of the bottom of the shroud 23, the inner side of the bottom of the cup seat 22, the inner side of the bottom of the main shell 11 and the sidewall of the bottom cover 12.

[0046] Through the above setting, when the motor 30 works, the cold air outside is transported into the shroud 23 through the air inlet of the main shell 42, the air inlet of the cup seat 43 and the air inlet of the shroud 44 arranged on the outer side of the main shell 11, the cup seat 22 and the shroud 23, so as to realize the heat dissipation of the motor 30. The hot air generated by the motor 30 is blown back into the first chamber 101 through the air outlet of the main shell 53, the air outlet of the cup seat 52 and the air outlet of the shroud 51 arranged on the inner side of the main shell 11, the cup seat 22 and the shroud 23, that is, the heat dissipation and noise reduction scheme of "outer side air inlet and inner side air outlet" is realized. The air inlet and air outlet paths do not interfere with each other, the structure is reasonable and reliable, and stable heat dissipation of the motor 30 is realized.

[0047] Further, the side of the main shell 11 facing the cup seat 22 is provided with a protruding part 111, and the air outlets of the main shell 53 are evenly distributed on the protruding part 111. The cup seat 22 is provided with a recessed part 221 corresponding to the position of the protruding part 111, and the air outlets of the cup seat 52 are evenly distributed on the recessed part 221, and the protruding part 111 and the recessed part 221 are closely matched.

[0048] Through the setting of the protruding part 111 and the recessed part 221, the bottom of the cup seat 22 is closely abutted with the bottom surface of the main shell 11, that is, the bottom of the cup seat 22 "sinks" to the bottom surface of the main shell 11, so that the noise generated by the motor 30 is difficult to be transmitted through the gap between the cup seat 22 and the main shell 11, and the noise reduction effect is further improved.

[0049] Further, referring to Figure 9 and Figure 10 A separation air guide structure for separating the air entering the first chamber 101 from the air outlet of the bottom cover 41 and the hot air entering and exiting the first chamber 101 from the air outlet of the main shell 53 is arranged in the first chamber 101. Through the arrangement of the separation air guide structure, the cold air outside blown into the first chamber 101 through the air inlet of the bottom cover 41 will not contact the hot air blown into the first chamber 101 from the air outlet of the main shell 53, so as to ensure the smoothness of the air inlet and the air outlet, and improve the heat dissipation efficiency.

[0050] Specifically, the separation air guide structure includes a vortex air duct 60 fixedly arranged on the bottom of the main shell 11. The top of the vortex air duct 60 is fixedly connected with the side of the main shell 11 facing the bottom cover 12, and the vortex air duct 60 extends vertically towards the bottom cover 12.

[0051] Further, the host shell air outlet 53 is located at one end of the vortex air duct 60, and the vortex air duct 60 spirally extends to the air outlet of the bottom cover 12 at the other end, so as to guide the hot air blown from the host shell air outlet 53 into the first chamber 101 to the bottom cover air outlet 54 for discharge.

[0052] It can be understood that, through the setting of the vortex air duct 60, the external cold air entering the first chamber 101 from the bottom cover air inlet 41 will not contact the hot air blown from the host shell air outlet 53, avoiding the turbulence and unstable air pressure of the first chamber 101, and realizing stable air intake and stable air outlet. At the same time, through the setting of the vortex air duct 60, the noise generated by the motor 30 working is further eliminated after entering the first chamber 101 through the air cover air outlet 51, the cup seat air outlet 52 and the host shell air outlet 53 and impacting on the inner wall of the vortex air duct 60, thereby improving the noise reduction effect.

[0053] In addition, the mixer provided by the utility model further comprises an electrical control mechanism 70, and the electrical control mechanism 70 is at least partially arranged on the host shell 11, for example, the host shell 11 with a control panel or a control knob. In order to realize electrical communication between the host shell 11 and the cup seat 22, the side of the host shell 11 facing the cup seat 22 is further provided with an electrical connection male seat 112 electrically connected with the electrical control mechanism 70, and the cup seat 22 is provided with an electrical connection female seat 222 matched with the electrical connection male seat 112 at the position corresponding to the electrical connection male seat 112, and the electrical connection female seat 222 is electrically connected with the motor 30, so that the electrical connection between the electrical control mechanism 70 and the motor 30 is realized, and the electrical control mechanism 70 can control the operation of the motor 30.

[0054] The working principle of the utility model is roughly as follows: when the motor 30 works, the heat dissipation blade 301 is driven to work, so that negative pressure is generated in the air cover 23, at this time, the external cold air is sucked into the air cover 23 of the second chamber 201 from the first chamber 101 from bottom to top through the first noise reduction air duct to heat the motor 30, and the heat generated by the motor 30 is blown into the first chamber 101 from top to bottom through the second noise reduction air duct and then discharged, so that stable heat dissipation of the motor 30 is realized, and the noise generated by the motor 30 is eliminated under the action of the first noise reduction air duct and the second noise reduction air duct, so that the mixer has better heat dissipation and noise reduction performance.

[0055] The above is only used to illustrate the technical scheme of the utility model and is not limited, and other modifications or equivalent replacements of the technical scheme of the utility model made by the ordinary skilled in the art should be covered in the claim range of the utility model.
