Description

Technical Field

[0001] The utility model belongs to the technical field of food processing, and in particular relates to a multifunctional meat grinder. Background Art

[0002] Traditional meat grinders have dual output mechanisms with different output speeds in the main machine. Users choose one of the output structures and install the corresponding processing parts to process the ingredients, achieving different grinding effects for different ingredients. The dual output mechanisms of this type of meat grinder are integrated in the main machine and cannot operate independently, and the gears are severely worn.

[0003] The patent with application number CN201721363814.7 discloses a new type of meat grinder, including a motor arranged in the main machine and a reduction gearbox detachably placed on the meat grinder cover. When the reduction gearbox is detached, the high-speed rotation of the stirring tool is realized by the high-speed operation of the motor, and the material is crushed at high speed. When the reduction gearbox is installed, the input end of the reduction gearbox is coupled with the output end of the motor, and the transmission output end of the reduction gearbox is connected to the stirring tool in the meat grinder container. At this time, the reduction gearbox cooperates with the motor to realize the slow rotation of the stirring tool.

[0004] In addition, when using an existing meat grinder, users usually place raw ingredients in the cup body for chopping, and then process and heat the chopped ingredients before eating. However, since raw ingredients carry some bacteria, highly active bacteria are not easily killed by high temperatures, which may cause discomfort to users after eating. Moreover, after using the meat grinder, users usually clean the cup body, assemble the main unit with the cup body and the cup lid in place for storage. If the user does not wipe or dry the cup body, bacteria are likely to breed in the cup body. If the air permeability of the cup body is poor, bacteria will multiply rapidly and cause mold and odor, etc., which brings a lot of inconvenience to users.

[0005] Therefore, how to further improve the user experience when using the meat grinder and realize the sterilization function of the meat grinder when the detachable reduction box and the main machine are installed or removed needs further research. Utility Model Content

[0006] The utility model provides a multifunctional meat grinder, which can realize various speed outputs of a main machine and various functions by flexibly disassembling and assembling a reduction box, and solves the problem of bacteria growth in a mixing cup.

[0007] The technical solution adopted by the utility model is:

[0008] A multifunctional meat grinder comprises a stirring cup, a cup cover and a main machine installed above the cup cover, the main machine comprises a main body with a motor installed therein and a reduction gearbox detachably installed at the lower end of the main body, the main machine has a first state in which the main body is independently installed on the cup cover and a second state in which the main body and the reduction gearbox are installed on the cup cover together, a first ultraviolet lamp capable of generating ozone is arranged inside the main body, a first air vent is arranged on the bottom wall of the main body, a second air vent is arranged on the cup cover, a third air vent and a fourth air vent which are connected to each other are arranged on the top wall and the bottom wall of the reduction gearbox respectively, and when the main machine is in the second state, the first air vent is connected to the second air vent through the third air vent and the fourth air vent.

[0009] By arranging a reduction gear box to be detachably mounted on the lower end of the main body, i.e., the output end of the main body, the reduction gear box and the output end of the main body are detachably connected, so that independent output at different speeds can be achieved. In the first state, the main body is independently mounted on the cup cover, and the motor runs at a high speed to realize high-speed crushing of the material by the meat grinder. In the second state, the reduction gear box is mounted on the cup cover together with the main body, and the reduction gear box cooperates with the output end of the main body to process the material slowly. That is, the reduction gear box is installed only when the meat grinder processes the material slowly, and the reduction gear box does not need to run at a high speed with the motor when the food is crushed at a high speed, which is beneficial to reducing the wear of the reduction gear box gears and increasing the service life of the reduction gear box. Moreover, since the reduction gear box is installed above the mixing cup, the reduction gear box is disassembled when the material is quickly crushed, so that the overall center of gravity of the meat grinder is lowered, which is beneficial to the overall stability of the meat grinder when the motor is running at a high speed, further improving the performance of the meat grinder, meeting the versatility and flexibility of use of the meat grinder, and enhancing the user experience.

[0010] By arranging a first ultraviolet lamp that can generate ozone inside the main body, since the density of ozone is relatively large and it tends to diffuse downward, the first ultraviolet lamp is arranged inside the main unit, and the main unit is installed above the cup cover and the blending cup. Then, the ozone generated in the main unit tends to diffuse downward to the blending cup, which is beneficial to achieving the disinfection and sterilization effect in the blending cup. Since the main body of the host has a first state of independent installation and a second state of simultaneous installation with the reduction gearbox, and the reduction gearbox is installed at the lower end of the main body, when the main body is independently installed, the main body is independently installed on the cup cover, and there is no other component blocking the main body and the cup cover, and the ozone generated by the first ultraviolet lamp enters the mixing cup through the first air vent and the second air vent, thereby achieving a sterilization effect on the mixing cup; when the main body is installed on the cup cover together with the reduction gearbox, since the reduction gearbox is located at the lower end of the main body, the diffusion of ozone is blocked, and by setting the third air vent and the fourth air vent, the first air vent is connected to the second air vent through the third air vent and the fourth air vent, then the ozone generated by the first ultraviolet lamp in the main body passes through the first air vent, the third air vent, the fourth air vent and the second air vent in sequence and then flows into the mixing cup, and when the reduction gearbox is installed together with the main body, effective sterilization of the mixing cup is still achieved, and the versatility of the meat grinder is achieved in combination with the detachable reduction gearbox.

[0011] Preferably, when the host is in the second state, the first air vent and the third air vent are laterally offset and connected.

[0012] Since gas has a tendency to diffuse in a direction with a lower pressure, and ozone itself has a high density and tends to flow downward, the first air port and the third air port are connected by a lateral misalignment, so that ozone can be guided from the first air port to the third air port, and ozone can be concentrated from the main body to the reduction box, and then to the cup cover and the mixing cup, so that ozone can sterilize the inside of the mixing cup. At the same time, by arranging the first air port and the third air port in a lateral misalignment, the light of the first ultraviolet lamp is scattered and refracted by the misaligned first air port and the third air port, so that ultraviolet rays are weakened, and the protection effect on human eyes is improved while satisfying the ozone circulation.

[0013] Preferably, an air duct is connected between the third air vent and the fourth air vent.

[0014] Because in the second state, a reduction gearbox is added to the lower end of the main body, which blocks the flow of ozone generated by the first ultraviolet lamp. Compared with the first state, on the one hand, the reduction gearbox itself has a certain structural setting, which will cause the flow path of ozone to become longer. On the other hand, after entering the reduction gearbox, the ozone will circulate and diffuse in the internal space of the reduction gearbox, and then escape into the mixing cup through the fourth air vent, affecting the sterilization efficiency of the ozone inside the mixing cup. By providing an air duct between the third air vent and the fourth air vent, that is, providing an air duct between the top wall and the bottom wall of the reduction gearbox, when the ozone flows from the third air vent to the fourth air vent, the ozone is concentratedly guided and circulated through the air duct, thereby accelerating the circulation speed of the ozone and helping to increase the ozone concentration in the mixing cup, thereby improving the sterilization efficiency of the second ultraviolet lamp on the inside of the mixing cup when the second state is achieved.

[0015] Preferably, the top wall of the reduction box is provided with an upper rib surrounding the third air vent, the bottom wall of the reduction box is provided with a lower rib surrounding the fourth air vent, and the upper rib is butted with the lower rib to form the air guide pipe;

[0016] Alternatively, the airway tube is a flexible tube.

[0017] By connecting the upper and lower surrounding ribs, an air duct is formed inside the reduction box, which improves the utilization rate of the internal space of the reduction box and is conducive to the rapid circulation of ozone between the top wall and the bottom wall of the reduction box, and realizes the centralized guidance of ozone from the third air port to the fourth air port, thereby improving the sterilization efficiency; and the upper and lower surrounding ribs are provided to strengthen the sealing effect around the third and fourth air ports, which is conducive to the circulation of ozone from the third air port to the fourth air port, and strengthens the concentration of ozone flowing into the mixing cup, thereby further improving the sterilization efficiency.

[0018] The air duct is set as a flexible tube, which is convenient for setting the direction of the air duct according to the internal structure of the reduction box and the matching connection structure between the reduction box, the main body and the cup cover, without affecting the original structure of the reduction box, and reasonably utilizing the space to set the air duct.

[0019] Preferably, the reduction gearbox includes an input shaft at the top end plug-fitted with the rotating shaft of the motor and an output shaft at the bottom end plug-fitted with the stirring member, and input holes and output holes corresponding to the input shaft and the output shaft are respectively provided on the top wall and bottom wall of the reduction gearbox, the third air vent is laterally staggered from the input hole, and the fourth air vent is laterally staggered from the output hole.

[0020] By setting the input hole, the input shaft and the output hole and the output shaft, a transmission connection is achieved between the reducer and the motor and the stirring blade in the stirring cup, thereby achieving the speed change effect of the reducer. The third air port is set to be laterally staggered with the input hole, and the transmission of the reducer and the circulation of ozone are realized from different positions respectively, avoiding the transmission interference of the third air port on the input shaft. Similarly, the fourth air port is set to be laterally staggered with the output hole to avoid the transmission interference of the fourth air port on the output shaft, thereby further ensuring the transmission effect of the reducer and improving the functional stability of the meat grinder, and realizing the circulation of ozone in the second state, and realizing the sterilization effect of the first ultraviolet lamp on the stirring cup.

[0021] Preferably, the reduction box includes an input shaft at the top end plugged with the rotating shaft of the motor and an output shaft at the bottom end plugged with the stirring member, and an input hole and an output hole corresponding to the input shaft and the output shaft are respectively provided on the top wall and the bottom wall of the reduction box, and the third air vent is formed between the input shaft and the input hole;

[0022] Alternatively, the reduction gearbox includes an input shaft plugged into the motor shaft and an output shaft cooperating with the input shaft, and an input hole and an output hole corresponding to the input shaft and the output shaft are respectively provided on the top wall and the bottom wall of the reduction gearbox, and the fourth air vent is formed between the output shaft and the output hole.

[0023] By forming a third air vent between the input shaft and the input hole, there is no need to open an additional air vent on the top wall of the reduction box, and the original connection structure is used to achieve the circulation of ozone, reducing the processing difficulty while achieving the sterilization effect of the first ultraviolet lamp.

[0024] By forming a fourth air vent between the output shaft and the output hole, there is no need to open an additional air vent on the bottom wall of the reduction box. The original connection structure is used to achieve the circulation of ozone, reducing the processing difficulty while achieving the sterilization effect of the first ultraviolet lamp.

[0025] Preferably, the bottom wall of the main body and the top wall of the reduction box are combined to form a first channel connecting the first air vent and the third air vent.

[0026] By setting the first channel, ozone flows from the first air vent along the first channel to the third air vent, realizing the centralized guidance and circulation of ozone, which is conducive to accelerating the ozone circulation rate and increasing the ozone concentration in the first channel, and further improving the sterilization efficiency of ozone. In addition, the first channel is formed by the bottom wall of the main body and the bottom wall of the reduction box, avoiding the need to directly set up another component between the main body and the reduction box, which is conducive to the circulation of ozone without affecting the connection between the main body and the reduction box, and does not change the connection structure between the two, thereby reducing the processing difficulty and installation burden.

[0027] Preferably, the fourth air vent is laterally offset from the second air vent, and a second passage connecting the fourth air vent with the second air vent is provided between the bottom wall of the reduction box and the upper surface of the cup cover.

[0028] By setting up the second channel, ozone flows from the fourth air port along the second channel to the second air port, thereby realizing concentrated guidance and circulation of ozone between the fourth air port and the second air port, which is beneficial to speed up the ozone circulation rate between the reduction box and the cup cover, and the ozone flows concentratedly along the second channel to the second air port, which is beneficial for the ozone to continue to flow from the second air port into the mixing cup, thereby enhancing the ozone concentration in the mixing cup and further improving the sterilization efficiency.

[0029] Preferably, a second ultraviolet lamp is provided inside the reduction box, and the second ultraviolet lamp generates ozone in the reduction box and discharges the ozone from the fourth air vent.

[0030] The second ultraviolet lamp is arranged in the reduction box. When the main body and the reduction box are in the second state, the second ultraviolet lamp is arranged to further increase the concentration of the generated ozone, and cooperate with the first ultraviolet lamp to achieve a better sterilization effect. The second ultraviolet lamp is closer to the fourth air vent, which is conducive to the generated ozone reaching the fourth air vent faster and flowing into the mixing cup, thereby improving the sterilization efficiency of the ozone. The ozone generated by the second ultraviolet lamp has a shorter flow path, which can further avoid the diffusion of ozone, so that more ozone flows into the mixing cup, further improving the sterilization efficiency.

[0031] Preferably, an electrical coupling structure is provided between the reduction box and the main body, and the second ultraviolet lamp is connected to the electrical coupling structure;

[0032] Alternatively, a control component is disposed inside the reduction box, the second ultraviolet lamp is connected to the control component, and a control button is installed on the side wall of the reduction box.

[0033] Since the second ultraviolet lamp is located inside the reduction box, an electric coupling structure is provided to facilitate turning on the second ultraviolet lamp in the second state, without having to turn on the second ultraviolet lamp manually, thus reducing the operation steps, simplifying the usage method, and improving the user experience. The control component and control button are provided to start and stop the second ultraviolet lamp, so that the second ultraviolet lamp can be turned on and off according to the usage requirements, meeting the different degrees of sterilization requirements of users and further improving the user experience.

DETAILED DESCRIPTION

[0046] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0047] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below. It should be noted that the embodiments of the present invention and the features in each embodiment may be combined with each other without conflict.

[0048] like Figures 1 to 8 As shown, the utility model provides a multifunctional meat grinder, including a stirring cup 30, a cup cover 20 and a main unit 10 installed above the cup cover 20, the main unit 10 including a main unit 101 with a motor therein and a reduction box 40 detachably installed at the lower end of the main unit 101, the main unit 10 has a first state in which the main unit 101 is independently installed on the cup cover 20 and a second state in which the main unit 101 and the reduction box 40 are installed on the cup cover 20 together, a first ultraviolet lamp 70 capable of generating ozone is provided inside the main unit 101, a first air vent 1011 is provided on the bottom wall of the main unit 101, a second air vent 201 is provided on the cup cover 20, a third air vent 401 and a fourth air vent 402 are respectively provided on the top wall and the bottom wall of the reduction box 40, and when the main unit 10 is in the second state, the first air vent 1011 is connected to the second air vent 201 through the third air vent 401 and the fourth air vent 402.

[0049] In the present solution, by arranging the reduction box 40 to be detachably installed at the lower end of the main body 101, that is, the output end of the main unit 10, the reduction box 40 is detachably connected to the output end of the main unit 10, which can realize independent output at different speeds, reduce gear wear, realize the high-speed meat grinding function and low-speed dough kneading function of the meat grinder, improve the performance of the meat grinder, meet the versatility and flexibility of use of the meat grinder, and enhance the user experience. By setting the reduction box 40 to be detachably mounted on the lower end of the main body 101, that is, the output end of the main body 101, the reduction box 40 and the output end of the main body 101 are detachably connected, so that independent output at different speeds can be achieved. In the first state, the main body 101 is independently mounted on the cup cover 20, and the motor runs at a high speed to realize the high-speed crushing of the material by the meat grinder. In the second state, the reduction box 40 is mounted on the cup cover 20 together with the main body 101, and the reduction box 40 cooperates with the output end of the main body 101 to process the material slowly, that is, the reduction box 40 is installed only when the meat grinder processes the material slowly. When the food is crushed at high speed, the reduction box 40 does not need to run at a high speed with the motor, which is beneficial to reducing the gear wear of the reduction box 40 and increasing the service life of the reduction box 10. Moreover, since the reduction box 10 is mounted above the mixing cup 30, when the material is quickly crushed, the reduction box 40 is disassembled, and the overall center of gravity of the meat grinder is lowered, which is beneficial to the overall stability of the meat grinder when the motor is running at a high speed, further improving the performance of the meat grinder, meeting the versatility and flexibility of use of the meat grinder, and enhancing the user experience. By setting a first ultraviolet lamp 70 that can generate ozone inside the main body 101, since the density of ozone is relatively large and it tends to diffuse downward, the first ultraviolet lamp 70 is set inside the main unit 10, and the main unit 10 is installed above the cup cover 20 and the blending cup 30, the ozone generated in the main unit 10 tends to diffuse downward to the blending cup 30, which is beneficial to achieve the disinfection and sterilization effect on the blending cup 30.Since the main body 101 of the host 10 has a first state of independent installation and a second state of simultaneous installation with the reduction box 40, and the reduction box 40 is installed at the lower end of the main body 101, when the main body 101 is independently installed, the main body 101 is independently installed on the cup cover 20, and there is no other component blocking between the main body 101 and the cup cover 20, the ozone generated by the first ultraviolet lamp 70 enters the blending cup 30 through the first air vent 1011 and the second air vent 201, thereby achieving a sterilization effect on the blending cup 30; when the main body 101 is installed on the cup cover 20 together with the reduction box 40, since the reduction box 40 is located at the lower end of the main body 101, the ozone generated by the first ultraviolet lamp 70 enters the blending cup 30 through the first air vent 1011 and the second air vent 201, thereby achieving a sterilization effect on the blending cup 30; when the main body 101 is installed on the cup cover 20 together with the reduction box 40, the reduction box 40 is located at the lower end of the main body 101, thereby achieving a sterilization effect on the blending cup 30. The diffusion of ozone is blocked by setting the third air port 401 and the fourth air port 402. The first air port 1011 is connected to the second air port 201 through the third air port 401 and the fourth air port 402. The ozone generated by the first ultraviolet lamp 70 in the main body 101 passes through the first air port 1011, the third air port 401, the fourth air port 402 and the second air port 201 in sequence and then flows into the mixing cup 30. When the reduction box 40 is installed together with the main body 101, the effective sterilization of the mixing cup 30 is still achieved, and the versatility of the meat grinder is achieved in cooperation with the detachable reduction box 40.

[0050] It should be noted that there are many ways to arrange the positions of the first air vent 1011 , the second air vent 201 , the third air vent 401 and the fourth air vent 402 .

[0051] like Figure 2 , Figure 3 As shown, in one embodiment, when the host 10 is in the second state, the first ventilation opening 1011 and the third ventilation opening 401 are laterally offset and connected.

[0052] Since gas has a tendency to diffuse in a direction with a lower pressure, and ozone itself has a high density and a tendency to flow downward, the first air vent 1011 and the third air vent 401 are connected in a transversely dislocated manner, so that ozone can be guided from the first air vent 1011 to the third air vent 401, and ozone can be concentrated from the main body 101 to the reduction box 40, and then to the cup cover 20 and the mixing cup 30, so that ozone can sterilize the inside of the mixing cup 30. At the same time, by dislocating the first air vent 1011 and the third air vent 401 in a transversely dislocated manner, the light of the first ultraviolet lamp 70 is scattered and refracted by the dislocated first air vent 1011 and the third air vent 401, so that ultraviolet rays are weakened, and the protection effect on human eyes is improved while satisfying the ozone circulation.

[0053] like Figure 2 As shown, in one embodiment, the bottom wall of the main body 101 and the top wall of the reduction box 40 are combined to form a first channel 50 that connects the first air vent 1011 and the third air vent 401 .

[0054] By setting the first channel 50, ozone flows from the first air vent 1011 along the first channel 50 to the third air vent 401, realizing the centralized guidance and circulation of ozone, which is conducive to accelerating the ozone circulation rate and increasing the ozone concentration in the first channel 50, and further improving the sterilization efficiency of ozone. In addition, the first channel 50 is formed by the bottom wall of the main body 101 and the bottom wall of the reduction box 40, avoiding the need to directly set up another component between the main body 101 and the reduction box 40, which is conducive to the circulation of ozone without affecting the connection between the main body 101 and the reduction box 40, and does not change the connection structure between the two, thereby reducing the processing difficulty and installation burden.

[0055] like Figure 2 As shown, in a preferred embodiment, the first air port 1011 and the third air port 401 are laterally offset so that the first channel 50 is extended laterally, so that the light of the ultraviolet lamp is scattered and refracted due to the offset first air port 1011 and the third air port 401. While ozone flows through the first channel 50, the ultraviolet rays can be weakened, thereby improving the protection effect on the human eyes.

[0056] It should be noted that the first channel 50 can be directly formed between the main body 101 and the reduction box 40 after the main body 101 and the reduction box 40 are assembled, or it can be formed by structurally improving the bottom wall of the main body 101 or the top wall of the reduction box 40. For example, a groove is provided on the bottom wall of the main body 101, or two convex ribs are provided on the top wall of the reduction box 40. When the reduction box 40 is installed, the first channel 50 is formed inside the groove or between the two convex ribs.

[0057] In one embodiment, an air duct 405 is connected between the third air vent 401 and the fourth air vent 402 .

[0058] Since the reduction box 40 is added at the lower end of the main body 101 in the second state, the circulation of the ozone generated by the first ultraviolet lamp 70 is blocked. Compared with the first state, on the one hand, the reduction box 40 itself has a certain structural setting, which will cause the circulation path of the ozone to become longer. On the other hand, after the ozone enters the reduction box 40, it will circulate and diffuse in the internal space of the reduction box 40, and then escape into the mixing cup 20 through the fourth air vent 402, affecting the sterilization efficiency of the ozone inside the mixing cup 20. By setting the air guide 405 between the third air vent 401 and the fourth air vent 402, that is, setting the air guide 405 between the top wall and the bottom wall of the reduction box 40, when the ozone flows from the third air vent 401 to the fourth air vent 402, the ozone is concentratedly guided and circulated through the air guide 405, the circulation speed of the ozone is accelerated, and it is beneficial to increase the ozone concentration in the mixing cup 30, thereby improving the sterilization efficiency of the second ultraviolet lamp 80 inside the mixing cup 30 when the second state is realized.

[0059] like Fig. 9As shown, in one embodiment, the top wall of the reduction box 40 is provided with an upper rib 403 surrounding the third air vent 401, and the bottom wall of the reduction box 40 is provided with a lower rib 404 surrounding the fourth air vent 402, and the upper rib 403 and the lower rib 404 are connected to form an air guide 405;

[0060] By connecting the upper surrounding rib 403 and the lower surrounding rib 404, an air duct 405 is formed inside the reduction box 40, which improves the internal space utilization rate of the reduction box 40 and facilitates the rapid circulation of ozone between the top wall and the bottom wall of the reduction box 40, thereby achieving centralized guidance of ozone from the third air port 401 to the fourth air port 402, and improving the sterilization efficiency; and the upper surrounding rib 403 and the lower surrounding rib 404 are provided to strengthen the sealing effect around the third air port 401 and the fourth air port 402, which is conducive to the circulation of ozone from the third air port 401 to the fourth air port 402, thereby enhancing the concentration of ozone flowing into the mixing cup 30 and further improving the sterilization efficiency.

[0061] It should be noted that the upper rib 403 and the lower rib 404 may be butted against each other in the following manner: Fig. 9 The upper rib 403 and the lower rib 404 are plugged together to form the air guide tube 405. The plugging method is conducive to the docking stability between the upper rib 403 and the lower rib 404, ensuring the stable air guiding effect of the air guide tube 405. In addition, the upper rib 403 and the lower rib 404 can also be abutted to form the air guide tube 405 (this method is not shown in the figure), which is simple in assembly and has lower processing difficulty.

[0062] like Figure 4 As shown, in one embodiment, the reduction box 40 includes an input shaft 406 located at the top end and plugged into the rotating shaft of the motor, and an output shaft 407 located at the bottom end and plugged into the stirring member, and input holes and output holes corresponding to the input shaft 406 and the output shaft 407 are respectively provided on the top wall and the bottom wall of the reduction box 40, the third air vent 401 is laterally staggered from the input hole, and the fourth air vent 402 is laterally staggered from the output hole.

[0063] By setting the input hole, input shaft 406 and the output hole and output shaft 407, a transmission connection is realized between the reducer and the motor and the stirring blade in the stirring cup 30, thereby realizing the speed change effect of the reducer. The third air port 401 is set to be laterally staggered with the input hole, and the transmission of the reducer and the circulation of ozone are realized from different positions respectively, avoiding the transmission interference of the third air port 401 on the input shaft 406. Similarly, the fourth air port 402 is set to be laterally staggered with the output hole to avoid the transmission interference of the fourth air port 402 on the output shaft 407. In this way, the transmission effect of the reducer can be further guaranteed, the functional stability of the meat grinder can be improved, and the circulation of ozone in the second state can be realized, so as to realize the sterilization effect of the first ultraviolet lamp 70 on the stirring cup 30.

[0064] Furthermore, an air duct 405 is provided between the third air port 401 which is laterally offset from the input hole and the fourth air port 402 which is laterally offset from the output hole, so as to avoid transmission interference with the input shaft 406 and the output shaft 407 of the reducer, strengthen the centralized guiding effect of ozone, and improve the sterilization efficiency and effect of the inside of the mixing cup 30.

[0065] like Figure 4 As shown, in another embodiment, the air guide tube 405 is a flexible tube. The air guide tube 405 is set as a flexible tube, which is convenient for setting the direction of the air guide tube 405 according to the internal structure of the reduction box 40 and the matching connection structure between the reduction box 40, the main body 101 and the cup cover 20, without affecting the original structure of the reduction box 40, and reasonably utilizing the space to set the air guide tube 405.

[0066] like Figure 5 As shown, in another embodiment, the reduction box 40 includes an input shaft 406 at the top end plugged with the rotating shaft of the motor and an output shaft 407 at the bottom end plugged with the stirring member, and an input hole and an output hole corresponding to the input shaft 406 and the output shaft 407 are respectively provided on the top wall and the bottom wall of the reduction box 40, and the third air vent 401 is formed between the input shaft 406 and the input hole;

[0067] By forming the third air vent 401 between the input shaft 406 and the input hole, there is no need to open an additional air vent on the top wall of the reduction box 40, and the original connection structure is used to achieve the circulation of ozone, reducing the processing difficulty while achieving the sterilization effect of the first ultraviolet lamp 70.

[0068] Alternatively, the reduction gearbox 40 includes an input shaft 406 plugged into the motor shaft and an output shaft 407 cooperating with the input shaft 406, and an input hole and an output hole corresponding to the input shaft 406 and the output shaft 407 are respectively provided on the top wall and the bottom wall of the reduction gearbox 40, and the fourth air vent 402 is formed between the output shaft 407 and the output hole.

[0069] By forming the fourth air vent 402 between the output shaft 407 and the output hole, it is also unnecessary to open an additional air vent on the bottom wall of the reduction box 40. The original connection structure is used to achieve the circulation of ozone, reducing the processing difficulty while achieving the sterilization effect of the first ultraviolet lamp 70.

[0070] It is understandable that the first air vent 1011, the second air vent 201, the third air vent 401 and the fourth air vent 402 can be arranged to be connected to each other to achieve the shortest path for ozone to flow to the blending cup 30, and while the ozone achieves the sterilization effect, some ultraviolet rays are still directly irradiated into the blending cup 30 for sterilization.

[0071] In addition, the first air vent 1011, the second air vent 201, the third air vent 401 and the fourth air vent 402 may be partially laterally staggered to produce a direction change during the ozone circulation process, thereby preventing direct ultraviolet rays from causing damage to human eyes.

[0072] like Figure 6 As shown, in a preferred embodiment, the fourth air vent 402 is laterally offset from the second air vent 201 , and a second channel 60 is provided between the bottom wall of the reduction box 40 and the upper surface of the cup cover 20 to connect the fourth air vent 402 with the second air vent 201 .

[0073] By setting up the second channel 60, ozone flows from the fourth air port 402 along the second channel 60 to the second air port 201, thereby realizing concentrated guidance and circulation of ozone between the fourth air port 402 and the second air port 201, which is beneficial to speed up the ozone circulation rate between the reduction box 40 and the cup cover 20, and the ozone flows concentratedly along the second channel 60 to the second air port 201, which is beneficial for ozone to continue to flow from the second air port 201 into the inside of the mixing cup 30, thereby enhancing the ozone concentration in the mixing cup 30 and further improving the sterilization efficiency.

[0074] It should be noted that the second channel 60 can be arranged in various forms, for example, Figure 6 As shown, an air guide groove is directly provided on the bottom wall of the reduction box 40 and the upper surface of the cup cover 20, and a raised retaining rib is provided on the bottom wall of the reduction box 40, and two retaining ribs are provided opposite to each other, and an air guide groove is formed between the two retaining ribs. Since the retaining ribs have a certain height, they can block the diffusion of ozone to both sides, further preventing ozone from diffusing to other parts, and concentrating the ozone along the second channel 60 and guiding it into the mixing cup 30.

[0075] Or, if Figure 7 As shown, the bottom wall of the reduction box 40 and the upper surface of the cup cover 20 are correspondingly provided with a step portion 90, and the fourth air vent 402 is opened on the step portion 90 of the bottom wall of the reduction box 40, and the second channel 60 is formed between the two step portions 90. The step portion 90 is used to support the structural strength of the second channel 60, and it is avoided to add other components, thereby reducing the difficulty of installation, achieving the centralized guiding effect of ozone through the second channel 60, and further improving the ozone sterilization efficiency.

[0076] like Figure 8 As shown, in one embodiment, a second ultraviolet lamp 80 is disposed inside the reduction box 40 , and the second ultraviolet lamp 80 generates ozone inside the reduction box 40 and discharges the ozone from the fourth air vent 402 .

[0077] The second ultraviolet lamp 80 is arranged in the reduction box 40. When the main body 101 and the reduction box 40 are in the second state, the second ultraviolet lamp 80 is arranged to further increase the concentration of the generated ozone, and cooperate with the first ultraviolet lamp 70 to achieve a better sterilization effect. In addition, the second ultraviolet lamp 80 is closer to the fourth air vent 402, which is conducive to the generated ozone reaching the fourth air vent 402 faster and flowing into the mixing cup 30, thereby improving the sterilization efficiency of the ozone. In addition, the ozone generated by the second ultraviolet lamp 80 has a shorter flow path, which can further avoid the diffusion of ozone, so that more ozone flows into the mixing cup 30, further improving the sterilization efficiency.

[0078] In one embodiment, an electrical coupling structure is provided between the reduction box 40 and the main body 101, and the second ultraviolet lamp 80 is connected to the electrical coupling structure;

[0079] Since the second ultraviolet lamp 80 is located inside the reduction box 40, an electrical coupling structure is provided to facilitate turning on the second ultraviolet lamp 80 in the second state. There is no need to turn on the second ultraviolet lamp 80 manually, which reduces the operation steps, simplifies the usage method, and improves the user experience.

[0080] Alternatively, in another embodiment, a control component is disposed inside the reduction box 40 , the second ultraviolet lamp 80 is connected to the control component, and a control button is installed on the side wall of the reduction box 40 .

[0081] A control component and a control button are set to start and stop the second ultraviolet lamp 80, and the second ultraviolet lamp 80 is turned on and off separately, so that the second ultraviolet lamp 80 can be turned on and off according to usage requirements, meeting users' sterilization needs to different degrees and further improving the user experience.

[0082] In one embodiment, the cup cover 20 is provided with a mounting groove with an opening facing upward, and when the host 10 is in the first state, the first ultraviolet lamp 70 is at least partially sunk into the mounting groove. In the first state, the bottom of the first ultraviolet lamp 70 is limited by the mounting groove, which enhances the stability of the first ultraviolet lamp 70, helps to ensure a good sterilization effect of the first ultraviolet lamp 70, and facilitates alignment installation through the mounting groove, thereby improving the installation speed and installation accuracy.
