Description

Technical Field

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

[0002] 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, it is not easy for highly active bacteria to be killed by high temperature, which may cause discomfort to users after eating. In addition, 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, the bacteria will multiply rapidly and cause mold, odor, etc., which brings a lot of inconvenience to the user.

[0003] Ultraviolet lamps are used to achieve sterilization in some existing food processing devices. For example, Chinese patent application number 202210726590.0 discloses a baby food machine, in which the UV lamp is installed under the blade and located in the material cup, so that the UV lamp can be installed completely exposed inside the food cup to disinfect the food cup; for another example, Chinese patent application number 202010389270.1 discloses a milk churn with a disinfection function, in which the UV lamp is installed inside the stirring body and facing the light-transmitting hole, so that the ultraviolet rays of the UV lamp are emitted from the light-transmitting hole to disinfect the parts to be disinfected.

[0004] However, a reduction gearbox is usually installed in the inner cavity of the meat grinder host. The housing of the reduction gearbox and the housing of the host are usually plastic parts. The ultraviolet light from the UV lamp will accelerate the aging of the plastic parts, causing the housing of the reduction gearbox to age and deform, resulting in the transmission of the meshing teeth and the planetary assembly on the inside to become stuck or even fail. When the host falls, the aging housing or the housing of the reduction gearbox may be damaged, greatly shortening its service life.

[0005] Therefore, during further research, the present applicant conceived of shielding the UV lamp for installation. However, if the UV lamp is simply shielded, the sterilization effect will be greatly reduced due to the shielding of the ultraviolet rays, which will cause the overall sterilization efficiency to be reduced and the sterilization to be incomplete.

[0006] Another Chinese patent with application number 202320563865.3 discloses a material storage device and a food processing machine with good sterilization effect. The sterilization device has a first working state of emitting ultraviolet radiation for sterilization into the material holding cavity and a second working state of generating ozone for sterilization into the material holding cavity. The sterilization device achieves dual sterilization effects of ultraviolet sterilization and ozone sterilization to enhance the sterilization effect.

[0007] However, in this solution, the air outlet of the air dispersion channel is located at the top, and the density of ozone is greater than that of air and cannot rise freely. Therefore, the discharge of ozone from the air outlet needs to rely entirely on the air dispersion structure, which makes air discharge difficult. The amount of ozone discharged from the connecting channel to the storage bin is low, and the diffusion rate of ozone in the material chamber is slow, resulting in a long sterilization time.

[0008] Therefore, under the premise of reducing the aging of plastic parts inside the main machine caused by ultraviolet rays, how to further improve the sterilization effect of food processing machines, especially relying on ozone generated by ultraviolet lamps for high-efficiency sterilization needs to be solved urgently. Utility Model Content

[0009] The utility model provides a food processor to solve the problems in the prior art that the ultraviolet lamp is exposed on the circuit board, causing internal parts to be aged and damaged due to direct irradiation, and the generated ozone cannot be concentrated and quickly flowed into the cavity of the mixing cup, resulting in poor sterilization effect.

[0010] The technical solution adopted by the utility model is:

[0011] A food processor comprises a mixing cup, a mixing piece installed in the mixing cup, and a main machine installed above the mixing cup. A motor assembly for driving the mixing piece is arranged in the main machine, and the motor assembly comprises a motor and a reduction box. An ultraviolet lamp and a lampshade installed outside the ultraviolet lamp are also arranged inside the main machine. The ultraviolet lamp generates ozone in the lampshade. An air vent is arranged at the bottom of the lampshade. An air outlet communicated with the air vent is arranged on the bottom wall of the main machine, and the air outlet is communicated with the inner cavity of the mixing cup.

[0012] By arranging a UV lamp inside the main machine and providing a lampshade outside the UV lamp to avoid the UV lamp being exposed, the UV rays can be prevented from directly irradiating the internal components of the main machine during the UV lamp irradiation process, thereby protecting the internal plastic parts and avoiding aging of the reduction box due to UV irradiation, thereby ensuring the meshing accuracy and transmission effect of the gears in the reduction box of the food processing machine, ensuring the service life of the reduction box and the stable operation of the food processing machine.

[0013] In addition, since the ultraviolet lamp will generate ozone when irradiated, a lampshade is provided to cover the ultraviolet lamp to prevent the generated ozone from escaping everywhere. The generated ozone is first concentrated in the lampshade through the lampshade, and then escapes along the air vent to the air outlet connected to the inner cavity of the mixing cup and flows from the air outlet to the inner cavity of the mixing cup. And since the air vent is provided at the bottom of the lampshade, it is conducive to the downward flow of the high-density ozone concentrated in the lampshade, realizing the concentration and flow direction guidance of the ozone, strengthening the sterilization effect in the mixing cup, improving the sterilization efficiency of the ultraviolet lamp, and improving the user experience.

[0014] Preferably, the food processor further comprises a cup cover arranged above the mixing cup, the cup cover is provided with a cup cover hole corresponding to the output shaft of the reduction gearbox, and a ventilation channel is provided between the ventilation port and the cup cover hole.

[0015] By setting up a ventilation channel, ozone will flow through the ventilation port along the ventilation channel, and the ozone will be guided centrally. Since the density of ozone is relatively large, it tends to diffuse downward. The lampshade is located inside the main unit, and the cup cover is covered on the mixing cup. The cup cover is located below the lampshade, which is conducive to the ozone flowing from the ventilation port along the ventilation channel to the cup cover hole, further improving the sterilization efficiency of the ultraviolet lamp, and avoiding opening a through hole in other parts of the cup cover to connect with the ventilation port, thereby avoiding material splashing or overflowing to cause blockage of the ventilation channel, ensuring the connectivity of the ventilation channel, allowing ozone to flow smoothly along the ventilation channel to the mixing cup, and ensuring the stability of the working effect of the ultraviolet lamp. In addition, the cup cover can also seal the mixing cup, which is easy to clean separately and can avoid the material in the mixing cup from splashing into the main unit to generate dirt or bacteria.

[0016] Preferably, the air outlet and the cup cover hole are laterally offset, and the air permeable channel includes a connecting channel arranged between the outer bottom wall of the main body and the upper surface of the cup cover, and the connecting channel connects the air outlet with the cup cover hole.

[0017] By dislocating the air outlet and the cup cover hole in a horizontal manner, the light of the ultraviolet lamp is scattered and refracted by the dislocated air outlet and the cup cover hole, thereby further weakening the ultraviolet rays and improving the protection effect on human eyes. At the same time, the formed connecting channel guides the ozone generated by the ultraviolet lamp to the inner cavity of the mixing cup, thereby achieving the sterilization effect of ozone on the inside of the mixing cup and improving the sterilization efficiency of the ultraviolet lamp.

[0018] Preferably, an upper groove is provided on the lower surface of the bottom wall of the main unit, and the upper groove and the cup cover are combined to form a communication channel;

[0019] Alternatively, a lower groove is provided on the upper surface of the cup cover, and the lower groove and the bottom wall of the main body are enclosed to form a communicating channel.

[0020] By setting an upper groove on the bottom wall of the main machine, the two ends of the upper groove are connected to the air outlet and the cup cover hole respectively, and when the cup cover is set above the stirring cup, a communication channel that bulges upward is formed between the cup cover and the bottom wall of the main machine, and ozone flows through the air vent to the air outlet connected to the air vent, and flows from the air outlet along the upper groove to the cup cover hole and then enters the inner cavity of the stirring cup, realizing the centralized guidance of the ozone flow direction, thereby achieving the sterilization of the inner cavity of the stirring cup and improving the sterilization efficiency. And the upper groove is formed by the bottom wall of the main machine, which is conducive to the circulation of ozone without changing the cup cover structure, and will not affect the internal space of the stirring cup after the cup cover is closed. Alternatively, by setting a lower groove on the upper surface of the cup cover, a downwardly concave communication channel is formed between the cup cover and the bottom wall of the main machine when the cup cover is closed, and the centralized guidance flow of ozone is also realized, accelerating its sterilization effect on the stirring cup. In addition, whether it is the setting of the upper groove or the setting of the lower groove, it is directly formed by the bottom wall of the main machine or the top wall of the cup cover, which can reduce the component connection structure when forming the communication channel and simplify the installation steps.

[0021] Preferably, the air vent is located at one side of the air outlet, and the air passage comprises an air guide passage arranged in the main unit, and the air guide passage extends transversely to connect the air vent with the air outlet.

[0022] By forming an air guide channel inside the main unit, ozone generated by the ultraviolet lamp flows from the air vent along the air guide channel to the air outlet connected to the inner cavity of the blending cup, thereby entering the inner cavity of the blending cup. At the same time, since the air guide channel is formed inside the main unit, the transversely extended air guide channel can prevent the light from the air vent from the direct exposure to the hole in the cup cover, thereby further achieving the effect of weakening the light of the ultraviolet lamp.

[0023] Preferably, the bottom wall of the main machine is provided with an axial hole corresponding to the output shaft of the reduction gearbox, and an air outlet is formed between the output shaft and the axial hole. The food processor also includes a cup cover arranged above the mixing cup, and the cup cover is provided with a cup cover hole corresponding to the output shaft of the reduction gearbox.

[0024] By setting the shaft hole and the cup cover hole corresponding to the output shaft, the air outlet and the cup cover hole are directly connected, and the ozone can flow from the air outlet to the cup cover hole more quickly and then reach the inner cavity of the blending cup, further improving the flow rate of ozone to achieve improved sterilization efficiency of the ultraviolet lamp. At the same time, the air outlet and the cup cover hole are arranged in a corresponding position to avoid setting a through hole on the bottom wall of the main unit to connect with the air vent, thereby reducing the difficulty of processing. When the air vent and the air outlet are arranged in a corresponding position, a part of the light can still irradiate the inner cavity of the blending cup through the air vent, the air outlet and the cup cover hole, thereby achieving the dual sterilization effect of ultraviolet light and ozone.

[0025] Preferably, the main machine comprises a shell and a bottom cover fixed to the bottom end of the shell, the shell comprises a main body and a step portion with an enlarged outer diameter relative to the main body from top to bottom, the reduction box is located in the step portion, the lampshade is located on one side of the reduction box, and the lampshade is fixedly connected to one of the step surface of the step portion, the housing of the reduction box and the bottom cover;

[0026] Alternatively, a cup cover is integrally formed on the bottom wall of the main unit, and the cup cover is fitted onto the stirring cup so that the air outlet is directly connected to the inner cavity of the stirring cup.

[0027] The reduction box and the lampshade are placed in a partitioned manner by setting a step portion. The step portion is formed by the expansion of the shell. The lampshade is set on one side of the reduction box. Since the step portion extends the shell in the horizontal direction and the lampshade is set on the side, it is beneficial to increase the distance from the air vent at the bottom of the lampshade to the air outlet or the cup cover hole at least in the horizontal direction, thereby further weakening the ultraviolet rays. In addition, the lampshade is fixedly connected to the step surface or the housing or bottom cover of the reduction box to enhance the integrity of the internal components of the main machine and enhance the stability of the lampshade during the operation of the food processor, thereby ensuring the realization of the sterilization effect. Alternatively, the cup cover is integrally formed with the main machine, and the cup cover is directly formed by the bottom wall of the main machine, which reduces the difficulty of installation, simplifies the use steps, and facilitates the user to quickly cover the mixing cup.

[0028] Preferably, the ultraviolet lamp includes a lamp tube and a lamp holder fixed at one end of the lamp tube, the lamp holder is connected to a lead, a socket is provided on the top wall of the lampshade, the lamp tube is inserted into the socket from top to bottom, and the lamp holder is located outside the lampshade and fixedly connected to the top wall of the lampshade.

[0029] The lamp holder is set to fix the lamp tube, so as to avoid the lamp tube shaking and position shifting during the operation of the food processing machine. The lamp holder can realize the centralized connection and arrangement of the lead wires, so as to avoid the appearance of messy wires and strengthen the orderliness and compactness of the connection between the lamp tube and the lead wires. The lamp tube is inserted from the top of the lampshade to avoid the opening in the side wall of the lampshade causing the light to be exposed from the side. The lamp holder is fixedly connected to the lampshade to further ensure the overall stability of the ultraviolet lamp and the lampshade, thereby ensuring the stability of the sterilization application of the ultraviolet lamp.

[0030] Preferably, the lampshade comprises a box body and a cover body which are separately arranged, the cover body is fixedly connected to the open end of the box body to enclose the box body to form an installation cavity, and a socket for inserting the ultraviolet lamp into the installation cavity is arranged on the box body.

[0031] By setting up the split molding of the lampshade, the UV lampshade is realized, and the jack and the cover are used to ensure the circumferential sealing effect of the lampshade on the UV lamp after the UV lamp is assembled. The split setting of the box body and the cover body reduces the difficulty of lampshade processing. At the same time, the combination of the box body and the cover body can achieve the circumferential covering effect of the UV lamp, realize the light weakening, and prevent ultraviolet rays from harming human eyes.

[0032] Preferably, the cover body and the box body are locked by a fastener;

[0033] Alternatively, a slide groove and a buckle position in the slide groove are provided at the open end of the box body, and the cover body is clamped in the slide groove through the buckle position.

[0034] The box body and the cover body are connected by fasteners. The fastener connection method is simple, the assembly stability is good, the assembly difficulty is low, the locking effect is good, and it is conducive to the long-term stable connection between the box body and the cover body. The box body and the cover body are connected by providing a slide groove and a buckle position located in the slide groove. This method directly forms the slide groove and the buckle position on the box body, reduces the connection of parts, and realizes simple and convenient assembly and disassembly between the box body and the cover body, and no additional parts are required, further reducing the production cost.

[0035] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0036] By arranging a UV lamp inside the main machine and arranging a lampshade outside the UV lamp to avoid the UV lamp being exposed, the UV lamp is prevented from directly irradiating the internal parts of the main machine during the UV lamp irradiation process, thereby protecting the internal plastic parts and avoiding the aging of the plastic box of the reduction box caused by UV irradiation, thereby ensuring the meshing accuracy and transmission effect of the gears in the reduction box of the food processing machine, ensuring the service life of the reduction box and the stable operation of the food processing machine. In addition, since the UV lamp will generate ozone when irradiating, a lampshade is arranged to cover the UV lamp to prevent the generated ozone from escaping everywhere, and the generated ozone is first concentrated in the lampshade through the lampshade, and then escapes along the air vent to the air outlet connected to the inner cavity of the mixing cup and flows from the air outlet to the inner cavity of the mixing cup. The air vent is at the bottom of the lampshade, which is conducive to the downward flow of the high-density ozone concentrated in the lampshade, realizing the concentration and flow direction guidance of the ozone, strengthening the sterilization effect in the mixing cup, improving the sterilization efficiency of the UV lamp, and improving the user experience.

DETAILED DESCRIPTION

[0051] 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.

[0052] 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.

[0053] like Figures 1 to 11As shown, the present application provides a food processor, including a mixing cup 20, a mixing piece installed in the mixing cup 20, and a main unit 10 installed above the mixing cup 20. A motor 40 assembly for driving the mixing piece is provided in the main unit 10. The motor 40 assembly includes a motor 40 and a reduction gearbox 50. An ultraviolet lamp 60 and a lampshade 70 covered on the outside of the ultraviolet lamp 60 are also provided inside the main unit 10. The ultraviolet lamp 60 generates ozone in the lampshade 70. An air vent 71 is provided at the bottom of the lampshade 70. An air outlet 11 connected to the air vent 71 is provided on the bottom wall 14 of the main unit 10. The air outlet 11 is connected to the inner cavity of the mixing cup 20.

[0054] The present application scheme arranges a UV lamp 60 inside the main unit 10 and arranges a lampshade 70 outside the UV lamp 60 to avoid the UV lamp 60 being exposed, thereby preventing the ultraviolet rays from directly irradiating the components inside the main unit 10 during the irradiation of the UV lamp 60, thereby protecting the internal plastic parts and avoiding aging of the plastic box of the reduction box 50 due to ultraviolet rays, thereby ensuring the meshing accuracy and transmission effect of the gears inside the food processor reduction box 50, ensuring the service life of the reduction box 50 and the stable operation of the food processor.

[0055] In addition, since the ultraviolet lamp 60 generates ozone when irradiated, a lampshade 70 is provided to cover the ultraviolet lamp 60 to prevent the generated ozone from escaping everywhere. The generated ozone is first concentrated in the lampshade 70 through the lampshade 70, and then escapes along the air vent 71 to the air outlet 11 connected to the inner cavity of the blending cup 20 and flows from the air outlet 11 to the inner cavity of the blending cup 20. The air vent 71 is at the bottom of the lampshade 70, which is conducive to the downward flow of high-density ozone concentrated in the lampshade 70, thereby realizing the concentration and flow direction guidance of ozone, enhancing the sterilization effect on the inside of the blending cup 20, improving the sterilization efficiency of the ultraviolet lamp 60, and improving the user experience.

[0056] Preferably, the lampshade 70 is made of solid ABS, which can not only prevent ultraviolet rays from leaking out and causing harm to human eyes, but also prevent other injection-molded parts in the main unit 10 from aging, breaking, or other component failures under the long-term exposure to the ultraviolet lamp 60, thereby further ensuring the stable operation of the food processor.

[0057] It should be noted that there are many ways for the vent 71 to communicate with the inner cavity of the mixing cup 20 through the vent 11, and the details can be referred to the following embodiments:

[0058] like Figures 4 to 6 As shown, the food processor further comprises a cup cover 30 which is arranged on top of the mixing cup 20 . The cup cover 30 is provided with a cup cover hole 31 corresponding to the output shaft of the reduction gearbox 50 , and a ventilation channel is provided between the ventilation port 71 and the cup cover hole 31 .

[0059] By setting up the ventilation channel, ozone will flow through the ventilation port 71 along the ventilation channel, and the ozone will be guided in a centralized manner. Since the density of ozone is relatively large, it tends to diffuse downward. The lampshade 70 is located inside the main unit 10, and the cup cover 30 covers the blending cup 20. The cup cover 30 is located below the lampshade 70, so it is beneficial for ozone to flow from the ventilation port 71 along the ventilation channel to the cup cover hole 31, further improving the sterilization efficiency of the ultraviolet lamp 60, and avoiding opening a through hole in other parts of the cup cover 30 to communicate with the ventilation port 71, thereby avoiding material splashing or overflowing to cause blockage of the ventilation channel, ensuring the connectivity of the ventilation channel, allowing ozone to flow smoothly along the ventilation channel to the blending cup 20, and ensuring the stability of the working effect of the ultraviolet lamp 60. In addition, the cup cover 30 can also seal the blending cup 20, and the cup cover 30 is easy to clean separately, and can avoid the material in the blending cup 20 splashing into the main unit 10 to generate dirt or bacteria.

[0060] It should be noted that there are multiple implementations of the structural arrangement of the air permeable channel, which may be any one of the following implementations:

[0061] Embodiment 1: The air outlet 11 and the cup cover hole 31 are arranged in a transverse offset manner, and the air permeable channel includes a connecting channel 80 arranged between the outer bottom wall 14 of the main body 10 and the upper surface of the cup cover 30 , and the connecting channel 80 connects the air outlet 11 with the cup cover hole 31 .

[0062] In this embodiment, the air outlet 11 and the cup cover hole 31 are arranged in a lateral offset manner, so that the light of the ultraviolet lamp 60 is scattered and refracted due to the offset air outlet 11 and the cup cover hole 31, thereby further weakening the ultraviolet rays and improving the protection effect on human eyes. At the same time, the formed connecting channel 80 guides the ozone generated by the ultraviolet lamp 60 to the inner cavity of the mixing cup 20, thereby achieving the sterilization effect of ozone on the inside of the mixing cup 20 and improving the sterilization efficiency of the ultraviolet lamp 60.

[0063] Furthermore, if Figure 4 As shown, the communication channel 80 is provided: an upper groove 141 is provided on the lower surface of the bottom wall 14 of the main body 10, and the upper groove 141 and the cup cover 30 are enclosed to form the communication channel 80;

[0064] By setting an upper groove 141 on the bottom wall 14 of the main unit 10, the two ends of the upper groove 141 are connected to the air outlet 11 and the cup cover hole 31 respectively, and the shaft hole 143 in the figure is directly connected to the cup cover hole 31. When the cup cover 30 is set on the top of the mixing cup 20, an upwardly raised communication channel 80 is formed between the cup cover 30 and the bottom wall 14 of the main unit 10, and ozone flows through the air vent 71 to the air outlet 11 connected to the air vent 71, and flows from the air outlet 11 along the upper groove 141 to the cup cover hole 31 and then enters the inner cavity of the mixing cup 20, realizing centralized guidance of the ozone flow direction, thereby achieving sterilization of the inner cavity of the mixing cup 20 and improving the sterilization efficiency. In addition, the upper groove 141 is formed by the bottom wall 14 of the main unit 10, which is conducive to the circulation of ozone without changing the structure of the cup cover 30, and will not affect the internal space of the mixing cup 20 after the cup cover 30 is closed.

[0065] Or, if Figure 5 As shown, a lower groove 32 is disposed on the upper surface of the cup cover 30 , and the lower groove 32 and the bottom wall 14 of the main body 10 are enclosed to form a communication channel 80 .

[0066] By providing the lower groove 32 on the upper surface of the cup cover 30, a downwardly recessed communication channel 80 is formed between the cup cover 30 and the bottom wall 14 of the main unit 10 when the cup cover 30 is closed, which also realizes the centralized guidance flow of ozone and accelerates its sterilization effect on the blending cup 20. In addition, whether the upper groove 141 or the lower groove 32 is provided, it is directly formed by the bottom wall 14 of the main unit 10 or the top wall of the cup cover 30, which can reduce the component connection structure when forming the communication channel 80 and simplify the installation steps.

[0067] In the first embodiment, the connecting channel 80 can be used as a ventilation channel. When ozone flows from the ventilation port 71 through the air outlet 11 to the cup cover hole 31, the connecting channel 80 can be used to guide the ozone to flow between the air outlet 11 and the cup cover hole 31, thereby improving the ozone diffusion efficiency.

[0068] Embodiment 2: The air vent 71 is located at one side of the air outlet 11 , and the air passage includes an air guide passage 90 disposed in the main unit 10 . The air guide passage 90 extends transversely to connect the air vent 71 with the air outlet 11 .

[0069] By forming an air guide channel 90 inside the main unit 10, the ozone generated by the ultraviolet lamp 60 flows along the air guide channel 90 from the air vent 71 to the air outlet 11 connected to the inner cavity of the blending cup 20, thereby entering the inner cavity of the blending cup 20. At the same time, since the air guide channel 90 is formed inside the main unit 10, the transversely extended air guide channel 90 can prevent the light from the air vent 71 from directly irradiating the cup cover hole 31, thereby further achieving the effect of weakening the light of the ultraviolet lamp 60.

[0070] Furthermore, if Figure 6As shown, the bottom wall 14 of the main machine 10 is provided with a raised retaining rib 20, and two retaining ribs 20 are provided opposite to each other. At the same time, the bottom wall 14 of the main machine 10 is provided with an axial hole 143 for the motor output shaft to pass through. The retaining rib extends along the bottom wall 14 of the main machine 10 to the axial hole 143, so as to form an air guide channel 90 connected with the axial hole 143 between the two retaining ribs 20. In this embodiment, the axial hole 143 is connected with the air vent 71 as the air outlet 11. Since the retaining rib 20 has a certain height, it can block the diffusion of ozone to both sides, further prevent the ozone from diffusing to other parts, and guide the ozone to the mixing cup 20 along the connecting channel 80.

[0071] In the second embodiment, the guide channel 90 can be used as a ventilation channel. When ozone flows from the ventilation port 71 through the air outlet 11 to the cup cover hole 31, the guide channel 90 can guide the ozone to flow between the ventilation port 71 and the air outlet 11, thereby improving the ozone diffusion efficiency.

[0072] It is understandable that the first embodiment and the second embodiment can be combined, and the connecting channel 80 and the air guide channel 90 are simultaneously provided to form a ventilation channel, so as to further achieve the effect of centralized guiding of ozone circulation.

[0073] Alternatively, a hose (not shown in the figure) is provided inside the main unit, and both ends of the hose are connected to the air vent 71 and the air outlet 11 respectively to form an air guide channel 90 inside the hose, and a connecting channel 80 as in the second embodiment is provided between the air outlet 11 and the cup cover hole 31. The hose and the connecting channel 80 are combined to form an air vent, thereby achieving a centralized guiding effect on the ozone in the process of flowing from the air vent 71 to the cup cover hole 31, so that more ozone can be concentrated and circulated into the stirring cup 20, thereby improving the sterilization efficiency of the ozone.

[0074] like Figure 7 As shown, the bottom wall 14 of the main unit 10 is provided with an axial hole 143 corresponding to the output shaft of the reduction gearbox 50, and an air outlet 11 is formed between the output shaft and the axial hole 143. The food processor also includes a cup cover 30 arranged above the mixing cup 20, and the cup cover 30 is provided with a cup cover hole 31 corresponding to the output shaft of the reduction gearbox 50.

[0075] In this embodiment, by setting the shaft hole 143 and the cup cover hole 31 to correspond to the output shaft, the air outlet 11 and the cup cover hole 31 are directly connected, so that ozone can flow from the air outlet 11 to the cup cover hole 31 more quickly and then reach the inner cavity of the blending cup 20, further improving the flow rate of ozone to achieve the improvement of the sterilization efficiency of the ultraviolet lamp 60. At the same time, the air outlet 11 and the cup cover hole 31 are arranged in a corresponding position and connected, avoiding the need to set a through hole on the bottom wall 14 of the main unit 10 to communicate with the air vent 71, thereby reducing the processing difficulty. When the air vent 71 and the air outlet 11 are arranged in a corresponding position, there is no horizontal channel between the two, and a part of the light can still irradiate the inner cavity of the blending cup 20 through the air vent 71, the air outlet 11 and the cup cover hole 31, thereby achieving the dual sterilization effect of ultraviolet rays and ozone.

[0076] like Figures 8 to 9 As shown, in one embodiment, the host 10 includes a shell and a bottom cover fixed to the bottom end of the shell, the shell includes a main body and a step portion 12 with an enlarged outer diameter relative to the main body from top to bottom, the reduction box 50 is located in the step portion 12, the lampshade 70 is located on one side of the reduction box 50, and the lampshade 70 is fixedly connected to one of the step surface 13 of the step portion 12, the housing of the reduction box 50 and the bottom cover;

[0077] The step portion 12 is provided to realize the partitioning of the reduction box 50 and the lampshade 70. The step portion 12 is formed by the expansion of the shell. The lampshade 70 is arranged on one side of the reduction box 50. Since the step portion 12 extends the shell in the horizontal direction and the lampshade 70 is arranged on the side, it is beneficial to increase the distance from the air vent 71 at the bottom of the lampshade 70 to the air outlet 11 or the cup cover hole 31 at least in the horizontal direction, and further realize the weakening of ultraviolet rays. In addition, the lampshade 70 is fixedly connected to the step surface 13 or the box body or bottom cover of the reduction box 50, so as to strengthen the integrity of the internal components of the main machine 10 and strengthen the stability of the lampshade 70 during the operation of the food processor, thereby ensuring the realization of the sterilization effect.

[0078] Alternatively, a cup cover 30 (not shown) is integrally formed on the bottom wall 14 of the main unit 10 , and the cup cover 30 covers the blending cup 20 , so that the air outlet 11 is directly connected to the inner cavity of the blending cup 20 .

[0079] In this way, the cup cover 30 is integrally formed with the main unit 10 , and the cup cover 30 is directly formed by the bottom wall 14 of the main unit 10 , which reduces the difficulty of installation, simplifies the use steps, and facilitates the user to quickly cover the blending cup 20 .

[0080] like Figure 2 As shown, the lampshade 70 is fixed to the step surface 13 by bolts, or as shown in FIG. Figure 7 As shown, the lamp cover is fixed to the bottom wall 14 of the host 10 by bolts.

[0081] It should be noted that there are many ways to fix the lampshade 70. In addition to fixing it with bolts, other fasteners can also be used to fix it.

[0082] In one embodiment, the ultraviolet lamp 60 includes a lamp tube and a lamp holder fixed at one end of the lamp tube, the lamp holder is connected to a lead, a socket 74 is set on the top wall of the lampshade 70, the lamp tube is inserted into the socket 74 from top to bottom, and the lamp holder is located outside the lampshade 70 and fixedly connected to the top wall of the lampshade.

[0083] In this embodiment, the lamp holder is provided to fix the lamp tube, so as to avoid the lamp tube from shaking and position shifting during the operation of the food processor, and the lamp holder is used to realize the centralized connection and arrangement of the lead wires, so as to avoid the appearance of disordered wires and enhance the orderliness and compactness of the connection between the lamp tube and the lead wires. The lamp tube is inserted from the top of the lampshade 70, so as to avoid the opening of the side wall of the lampshade 70 causing the light to be exposed from the side, and the lamp holder is fixedly connected to the lampshade 70, so as to further ensure the overall stability of the ultraviolet lamp 60 and the lampshade 70, thereby ensuring the stability of the sterilization application of the ultraviolet lamp 60.

[0084] like Figure 10 to Figure 11 As shown, in another embodiment, the lampshade 70 includes a box body 72 and a cover body 73 which are separately arranged. The cover body 73 is fixedly connected to the open end of the box body 72 to enclose the box body 72 to form an installation cavity 75. The box body 72 is provided with a socket 74 for inserting the ultraviolet lamp 60 into the installation cavity 75.

[0085] By setting the lampshade 70 to be formed in a split form, the ultraviolet lamp 60 can be covered, and the jack 74 and the cover 73 can be used to ensure that the lampshade 70 has a circumferential sealing effect on the ultraviolet lamp 60 after the ultraviolet lamp 60 is assembled. The split setting of the box body 72 and the cover body 73 reduces the difficulty of processing the lampshade 70. At the same time, the combination of the box body 72 and the cover body 73 can achieve a circumferential covering effect on the ultraviolet lamp 60, thereby weakening the light and preventing ultraviolet rays from harming human eyes.

[0086] Further, the cover 73 and the box body 72 are locked by fasteners;

[0087] The box body 72 and the cover body 73 are connected by fasteners. The fastener connection method is simple, the assembly stability is good, the assembly difficulty is low, and the locking effect is good, which is conducive to the long-term stable connection between the box body 72 and the cover body 73.

[0088] It should be noted that the fasteners may be screws or other types of fixing connectors, and there is no specific limitation on this.

[0089] Alternatively, the open end of the box body 72 is provided with a slide groove 721 and a buckle position 722 located in the slide groove 721 , and the cover body 73 is clamped in the slide groove 721 through the buckle position 722 .

[0090] The connection between the box body 72 and the cover body 73 is achieved by providing a slide groove 721 and a buckle position 722 located in the slide groove 721. In this way, the slide groove 721 and the buckle position 722 are directly formed on the box body 72, which reduces the connection of parts and realizes simple and convenient assembly and disassembly between the box body 72 and the cover body 73. There is no need to configure additional parts, which further reduces the production cost.

[0091] like Fig.11 As shown, specifically, two slide grooves 721 are provided at the assembly position of the open end of the box body 72 and the cover body 73. During assembly, the cover body 73 is plugged and assembled with the shell through the slide grooves 721. Two protrusions are provided on both sides of the cover body 73, and two buckle positions 722 are provided on both sides of the box body 72 corresponding to the protrusion positions. When the cover body 73 slides to the assembly position through the slide grooves 721, the protrusions are buckled into the buckle positions 722, and the protrusions and the buckle positions 722 are fixed by the interference fit.
