Description

Technical Field

[0001] The utility model belongs to the technical field of food processing devices, and in particular relates to a meat grinder. 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 may carry some bacteria, it is not easy for highly active bacteria or viruses 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, the existing meat grinder products cannot achieve the sterilization function. In addition, in the above food processing devices, although ultraviolet rays can be used for sterilization and disinfection, the UV lamps are mostly exposed or facing the light-transmitting holes, and the cup body of the meat grinder is mostly made of glass. If an ultraviolet lamp is added for sterilization, the ultraviolet light will be projected to the outside during user use, causing discomfort to the user's eyes. Even if the ultraviolet rays of the food processing device do not directly shine into the user's eyes during use, there is a risk of the ultraviolet light directly shining into the user's eyes when the user removes or rotates the host.

[0005] Moreover, for meat grinders, in order to expand their functions, some existing meat grinders can not only grind meat and chop vegetables, but also be used for dough. When users need to make large quantities of meat, they need to operate for a long time in multiple times. When users need to mix dough, the time for a single mixing generally varies from 3 to 10 minutes. During this process, users need to keep pressing the meat grinder and observe the ingredients in the mixing cup. The usage time is relatively long, so it is necessary to consider the eye fatigue and discomfort caused by long-term exposure to ultraviolet light, which will increase the impact on users.

[0006] Therefore, there is an urgent need for a meat grinder that can sterilize and reduce the impact of ultraviolet light on users. Utility Model Content

[0007] The utility model provides a meat grinder, which solves the problem that bacteria are easily bred in a cup body of the meat grinder and that ultraviolet rays irradiate the cup body for a long time to affect the user's eyes when used for a long time.

[0008] To achieve the above-mentioned purpose, the utility model provides a meat grinder, comprising a stirring cup with a built-in stirring piece, a cup cover, and a main unit with a built-in motor assembly, the stirring piece passes through the cup cover and is transmission-connected to the motor assembly, the main unit is a plastic shell, an ultraviolet lamp is also arranged in the main unit, the ultraviolet lamp generates ozone in the main unit, the cup cover is provided with a mounting groove with an opening facing upward for mounting the main unit, an air outlet is arranged on the bottom wall of the main unit, a connecting port is provided on the bottom wall of the mounting groove, the connecting port is connected with the air outlet to allow ozone to enter the stirring cup, after the main unit is installed in place, the air outlet and the horizontal projection of the ultraviolet lamp do not overlap, and the ultraviolet lamp is at least partially sunk into the mounting groove.

[0009] The meat grinder provided by the utility model has an ultraviolet lamp in the main unit. The ultraviolet lamp irradiation will generate ozone in the main unit. The ozone enters the mixing cup through the air outlet on the bottom wall of the main unit and the connecting port of the cup cover in turn, sterilizes and disinfects the inside of the mixing cup, sterilizes the meat grinder, and alleviates the problem of bacteria easily breeding in the mixing cup. In addition, the air outlet and the horizontal projection of the ultraviolet lamp do not overlap, that is, the two are staggered, so that the light of the ultraviolet lamp will not be directly emitted through the air outlet, and the structure inside the main unit directly below the ultraviolet lamp will block the ultraviolet rays, thereby reducing the ultraviolet light projected into the mixing cup. Especially when the user uses the meat grinder for a long time, for example, when using the meat grinder to knead dough, the effect of the ultraviolet light on the user's eyes when the user stares at the mixing cup for a long time is reduced, and the eye fatigue caused by the long-term ultraviolet light exposure is alleviated.

[0010] Moreover, when the main unit and the cup cover are installed in place, at least part of the ultraviolet lamp is sunk into the installation groove, and the side groove walls of the installation groove surround the local periphery of the main unit to prevent the light of the ultraviolet lamp from radiating out laterally. The light of the ultraviolet lamp needs to pass through the plastic shell of the main unit and the groove walls of the installation groove in sequence laterally before it can be projected to the outside. The main unit shell and the groove walls of the installation groove play a double shielding role for the laterally emitted ultraviolet rays, thereby further reducing the impact of ultraviolet rays on users during long-term use.

[0011] In this way, the meat grinder of the utility model can not only block the ultraviolet rays projected downward into the mixing cup by the ultraviolet lamp, but also block the ultraviolet rays projected laterally, thereby greatly reducing the ultraviolet rays irradiating the outside of the meat grinder. This not only enables the ultraviolet lamp to have a better sterilization and disinfection effect on the inside of the mixing cup, but also reduces the impact of ultraviolet rays on the user's eyes when the user uses it for a long time, thereby improving the user experience.

[0012] Preferably, the meat grinder comprises a barrier portion for blocking ultraviolet rays, and the barrier portion is fixed inside the main unit or inside the mounting groove.

[0013] The blocking part can further block the ultraviolet light emitted by the ultraviolet lamp, reducing the ultraviolet light from irradiating into the inside of the blender cup and / or the outside of the main unit housing. In this solution, the blocking part can form a third barrier for the ultraviolet light emitted by the ultraviolet lamp to irradiate laterally outward, and together with the main unit housing and the groove wall of the installation groove, form a triple shielding protection, thereby greatly improving the shielding effect of ultraviolet light.

[0014] Preferably, the barrier part is a lampshade installed outside the ultraviolet lamp, the ultraviolet lamp is completely immersed in the inner cavity of the lampshade, and an air vent is opened on the lampshade; or, the barrier part includes an air collecting channel arranged inside the main unit and a lampshade arranged at the inlet end of the air collecting channel, the lampshade and the air collecting channel enclose a accommodating cavity for accommodating the ultraviolet lamp, and the outlet of the air collecting channel is connected to the air outlet; or, the barrier part is a baffle separating the ultraviolet lamp and the side wall of the main unit; or, the barrier part is an anti-ultraviolet coating coated on the inner wall surface of the main unit or the mounting groove.

[0015] The UV lamp is completely sunken into the inner cavity of the lampshade, so that the lampshade can block the ultraviolet light emitted by the UV lamp at more angles, thereby not only blocking the ultraviolet light irradiating downward and horizontally outward, but also blocking the ultraviolet light irradiating toward the inside of the main unit or irradiating upward, thereby fully surrounding the UV lamp and blocking the ultraviolet light from being exposed in all directions. The setting of the air vent facilitates the discharge of ozone generated in the lampshade, which is connected to the air outlet through the air vent, thereby allowing the ozone to enter the blender cup.

[0016] The wind channel and the lampshade can also fully surround the UV lamp. The UV lamp is located in the accommodating cavity. The channel wall and the lampshade of the wind channel block the UV rays, reducing the UV rays irradiated to the outside of the main unit. At the same time, the setting of the wind channel also improves the guiding effect on ozone, so that ozone flows quickly to the air outlet under the guidance of the wind channel, thereby improving the flow efficiency of ozone, making it flow more quickly and smoothly to the inside of the mixing cup, thereby improving the sterilization efficiency.

[0017] By setting a baffle between the ultraviolet lamp and the side wall of the main unit, or applying an anti-ultraviolet coating on the inner wall of the main unit or the installation groove to form a barrier, compared with the method of completely surrounding the ultraviolet lamp for blocking, the structure and volume of the barrier can be simplified, thereby reducing the space occupied by the barrier, saving the internal space of the main unit, helping to reduce the volume of the main unit and achieve miniaturization.

[0018] Preferably, after the host is installed in place, the ultraviolet lamp is completely sunk into the installation groove.

[0019] After the main unit is installed in place, the UV lamp is completely sunk into the installation groove, and the side groove walls of the installation groove surround the UV lamp in a circumferential direction, so that the side groove walls of the installation groove can completely block the ultraviolet rays emitted laterally by the UV lamp in the height direction, thereby improving the UV shielding effect of the installation groove.

[0020] Preferably, the ultraviolet lamp comprises a lamp tube, which is a straight tube vertically arranged on one side of the motor assembly. After the main unit is installed in place, at least half of the lamp tube in the height direction extends into the installation groove.

[0021] The wall of the installation groove at least blocks half of the lamp tube from bottom to top, and on the basis of having a good shielding effect on the ultraviolet rays emitted by the ultraviolet lamp, the depth of the installation groove can be reduced accordingly, thereby reducing the overall thickness of the cup cover, making the cup cover lighter and more convenient for users to take. At the same time, the thinning of the cup cover also makes the overall appearance of the meat grinder lighter and more beautiful, improving the visual experience of users.

[0022] Preferably, the ultraviolet lamp comprises a lamp tube, which is a curved tube arranged around the outer circumference of the motor assembly.

[0023] The ultraviolet lamp is a curved tube and is arranged around the motor assembly, which rationally utilizes the space between the inner wall of the main unit and the motor assembly, thereby optimizing the structural layout inside the main unit. At the same time, the curved tube structure extending along the circumference of the motor assembly can also increase the length of the ultraviolet lamp and the area covered by the ultraviolet lamp, thereby increasing the amount of ozone produced and improving the sterilization efficiency. In addition, the ultraviolet lamp surrounds the outer periphery of the motor assembly, so that when the ultraviolet lamp is turned on, ozone will be evenly produced around the motor assembly, and then evenly enter the inside of the mixing cup through the air outlet, and evenly distributed around the circumference of the mixing cup, thereby improving the uniformity of ozone distribution in the mixing cup, ensuring the thoroughness of sterilization and disinfection, and avoiding the generation of sterilization dead corners that lead to bacterial residues.

[0024] Preferably, the bottom wall of the main unit is provided with an axial hole through which the output shaft of the power supply motor assembly is exposed, an air outlet is formed between the output shaft and the axial hole, and the connecting port is a through hole for a stirring member to pass through so as to be transmission-connected to the output shaft, or the cup cover is provided with a through hole for a stirring member to pass through so as to be transmission-connected to the motor assembly, and the connecting port and the through hole are staggered.

[0025] The axial hole on the bottom wall of the main unit is used as the outlet of the output shaft and forms an air outlet with the output shaft for discharging ozone in the main unit, so that the transmission connection between the main unit and the stirring member, and the connection between the main unit and the ozone in the stirring cup share an opening, which reduces the number of openings on the bottom wall of the main unit, simplifies the structure of the main unit, and reduces the difficulty of processing. In addition, the through hole is generally provided with an anti-overflow structure for preventing food from overflowing from the stirring cup. The air outlet and the connecting port are aligned up and down, and the anti-overflow structure can also prevent food from overflowing from the connecting port, and there is no need to set an additional anti-overflow structure at the air outlet. In addition, since the axial hole and the connecting port generally correspond to the center of the stirring cup, ozone will enter the inside of the stirring cup from the center of the stirring cup through the air outlet, and then diffuse and flow around, thereby improving the uniformity of ozone distribution in the stirring cup.

[0026] The staggered arrangement of the connecting port and the through hole can flexibly adjust the opening position of the connecting port on the cup cover according to the location of the UV lamp and the spatial layout inside the main unit. This helps to shorten the air path length between the main unit and the blender cup, reduce the kinetic energy loss of ozone flow, allow ozone to enter the blender cup more quickly, and improve sterilization efficiency.

[0027] Preferably, the cup cover is recessed downward to form a mounting groove, the bottom wall of the mounting groove is lower than the cup mouth of the blending cup, and the ultraviolet lamp is at least partially sunk into the cup mouth of the blending cup.

[0028] At least a portion of the ultraviolet lamp is sunken into the mouth of the blending cup, so that the ultraviolet rays irradiated laterally outward by the ultraviolet lamp are not only blocked by the main body shell and the installation groove wall, but also by the wall of the blending cup, thereby forming three shieldings for the laterally irradiated ultraviolet rays, thereby greatly reducing the ultraviolet rays irradiated to the outside of the blending cup, allowing the user to observe the food inside the blending cup more clearly and reducing the impact of ultraviolet rays on the user's eyes.

[0029] Preferably, a light-shielding sleeve is provided on the mixing cup at a position which highly overlaps with the ultraviolet lamp.

[0030] The wall of the blending cup is mostly made of glass or transparent plastic, which has poor light-shielding performance. By installing a light-shielding cover on the part where the blending cup and the ultraviolet lamp are highly overlapped, the part can have better light-shielding performance, thereby achieving a better shielding effect on the ultraviolet rays irradiated outward by the ultraviolet lamp.

[0031] Preferably, the cup cover further comprises an outer cover body extending outwardly from the top end of the side wall of the mounting groove to the mouth of the stirring cup, and the outer cover body comprises an annular wall surrounding the outer side of the mounting groove.

[0032] The annular wall surrounds the outer circumference of the installation groove, serving as the third shielding against the ultraviolet rays irradiated laterally by the ultraviolet lamp. The ultraviolet rays are blocked from the inside to the outside by the main unit casing, the side walls of the installation groove and the annular wall in sequence, and the light intensity gradually decreases, so that the user will not feel the glare from the outside, especially when using the meat grinder for a long time, and can get a better visual experience and usage experience.

[0048] 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.

[0049] In the description of the present invention, it is necessary to understand that the terms "top", "bottom", "inside", "outside", "axial", "circumferential", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0050] In the description of this specification, the description with reference to the terms "implementation mode", "embodiment", "one embodiment", "example" or "specific example" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. The specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0051] like Figure 1 As shown, a meat grinder comprises a stirring cup 1 with a built-in stirring element 11, a cup cover 2, and a main unit 3 with a built-in motor assembly 31. The stirring element 11 passes through the cup cover 2 and is transmission-connected to the motor assembly 31. The main unit 3 is a plastic shell. An ultraviolet lamp 4 is also provided in the main unit 3. The ultraviolet lamp 4 generates ozone in the main unit 3. The cup cover 2 is provided with a mounting groove 21 with an opening facing upward for mounting the main unit 3. An air outlet 32 ​​is provided on the bottom wall of the main unit 3. A connecting port 22 is provided on the bottom wall of the mounting groove 21. The connecting port 22 is connected to the air outlet 32 ​​to allow ozone to enter the stirring cup 1. After the main unit 3 is installed in place, the air outlet 32 ​​does not overlap with the horizontal projection of the ultraviolet lamp 4, and the ultraviolet lamp 4 is at least partially sunk into the mounting groove 21.

[0052] In the utility model, the main unit 3 is a plastic shell. The plastic material is low in cost, which can reduce the manufacturing cost of the main unit 3 and even the entire meat grinder. In addition, the plastic shell is light in weight, making the main unit 3 lighter as a whole, making it easier for users to take the main unit 3, and making the operation more convenient and comfortable.

[0053] The meat grinder provided by the utility model has an ultraviolet lamp 4 disposed in the main unit 3. The ultraviolet lamp 4 irradiates and generates ozone in the main unit 3. The ozone enters the mixing cup 1 through the air outlet 32 ​​on the bottom wall of the main unit 3 and the connecting port 22 of the cup cover 2 in turn, sterilizes and disinfects the inside of the mixing cup 1, sterilizes the meat grinder, and alleviates the problem of bacteria easily growing in the mixing cup 1. In addition, the air outlet 32 ​​and the horizontal projection of the ultraviolet lamp 4 do not overlap, that is, the two are arranged in a staggered manner, so that the light of the ultraviolet lamp 4 will not be directly emitted through the air outlet 32, and the structure inside the main unit 3 located directly below the ultraviolet lamp 4 will block the ultraviolet rays, thereby reducing the ultraviolet rays projected into the mixing cup 1. Especially when the user uses the meat grinder for a long time, for example, when the meat grinder is used for dough processing, the effect of the ultraviolet rays on the user's eyes when the user stares at the mixing cup 1 for a long time is reduced, and the eye fatigue caused by the ultraviolet rays is alleviated.

[0054] Moreover, when the main unit 3 and the cup cover 2 are installed in place, at least part of the ultraviolet lamp 4 is sunk into the mounting groove 21, and the side groove wall of the mounting groove 21 surrounds the local periphery of the main unit 3 to prevent the light of the ultraviolet lamp 4 from irradiating laterally. The light of the ultraviolet lamp 4 needs to pass through the plastic shell of the main unit 3 and the groove wall of the mounting groove 21 in sequence laterally before it can be projected to the outside. The outer shell of the main unit 3 and the groove wall of the mounting groove 21 play a double shielding role for the laterally emitted ultraviolet rays, thereby further reducing the impact of ultraviolet rays on users during long-term use.

[0055] In this way, the meat grinder of the present invention can not only block the ultraviolet rays projected downward by the ultraviolet lamp 4 into the mixing cup 1 to a certain extent, but also block the ultraviolet rays projected laterally to a certain extent, thereby greatly reducing the ultraviolet rays irradiated to the outside of the meat grinder, which not only enables the ultraviolet lamp 4 to have a better sterilization and disinfection effect on the inside of the mixing cup 1, but also can reduce the impact of ultraviolet rays on the user's eyes when the user uses it for a long time, thereby improving the user experience.

[0056] Specifically, the emission spectrum of the ultraviolet lamp 4 includes two regions of 254 nanometers and 185 nanometers, wherein 185 nanometers corresponds to the ozone band ultraviolet rays. The spectrum of the ultraviolet lamp 4 of the utility model includes ultraviolet rays of 185 nanometers, which will produce ozone under appropriate irradiation conditions, such as strong ultraviolet irradiation. Then, by passing the ozone into the mixing cup 1, the inside of the mixing cup 1 is sterilized and disinfected.

[0057] It should be noted that the present invention does not limit the way in which ozone enters the mixing cup 1. In one embodiment, Figure 1As shown, the main unit 3 is located above the blending cup 1, and the ultraviolet lamp 4 is located inside the main unit 3. When the ultraviolet lamp 4 generates ozone inside the main unit 3, since the density of ozone is greater than that of air, it will naturally flow downward, and then enter the blending cup 1 through the air outlet 32 ​​and the connecting port 22. In this embodiment, the characteristic that the density of ozone is greater than that of air is utilized to make the ozone naturally flow downward into the blending cup 1, without the need to set up additional drainage structures and blowing parts, thereby simplifying the internal structure of the main unit 3 and saving costs.

[0058] In another embodiment, a blowing component, such as a fan, may also be provided in the main unit 3 to blow the ozone generated by the ultraviolet lamp 4 downward into the blending cup 1, thereby shortening the time for ozone to enter the blending cup 1, improving the flow efficiency of ozone, and further improving the sterilization efficiency.

[0059] As a preferred embodiment of the present invention, Figure 2 As shown, the meat grinder includes a barrier portion 5 for blocking ultraviolet rays, and the barrier portion 5 is fixed inside the main unit 3 or inside the mounting groove 21.

[0060] The baffle 5 can further block the ultraviolet light emitted by the ultraviolet lamp 4, reducing the ultraviolet light from irradiating the inside of the blender cup 1 and / or the outside of the housing of the main unit 3. In this solution, the baffle 5 can form a third barrier for the ultraviolet light emitted by the ultraviolet lamp 4 to irradiate laterally outward, and together with the housing of the main unit 3 and the wall of the installation groove 21, form a triple shielding protection, thereby greatly improving the shielding effect of ultraviolet light.

[0061] It should be noted that the barrier 5 is used to block ultraviolet rays, but the utility model does not limit the shielding position of the barrier 5 on the ultraviolet lamp 4. For example, the barrier 5 can fully surround the ultraviolet lamp 4 to block the ultraviolet rays emitted from the upper and lower sides and the circumferential direction of the ultraviolet lamp 4, thereby forming an all-round shielding of the ultraviolet lamp 4. For another example, the barrier 5 can also be located at least one position above, below, and in the circumferential direction of the ultraviolet lamp 4 to specifically shield the ultraviolet rays emitted from a certain direction or angle.

[0062] Specifically, the structure of the baffle 5 includes but is not limited to the following embodiments:

[0063] Embodiment 1: In this embodiment, as Figures 3 to 6 As shown, the barrier 5 is a lampshade 51 which is mounted outside the ultraviolet lamp 4 . The ultraviolet lamp 4 is completely immersed in the inner cavity of the lampshade 51 . A vent 511 is provided on the lampshade 51 .

[0064] The ultraviolet lamp 4 is completely sunken into the inner cavity of the lampshade 51, so that the lampshade 51 can block the ultraviolet rays emitted by the ultraviolet lamp 4 at more angles, thereby not only blocking the ultraviolet rays irradiated downward and laterally outward, but also blocking the ultraviolet rays irradiated toward the inside of the main unit 3 or irradiated upward, thereby fully surrounding the ultraviolet lamp 4 and blocking the ultraviolet rays from being exposed in all directions. The provision of the vent 511 facilitates the discharge of ozone generated in the lampshade 51, and the vent 511 is connected to the air outlet 32, thereby allowing ozone to enter the mixing cup 1.

[0065] It should be noted that if Figure 4 , Figure 5 As shown, the ultraviolet lamp 4 includes a lamp tube 41 capable of emitting ultraviolet rays, and a lamp holder 42 for mounting the lamp tube 41 on the host 3, wherein the lamp tube 41 and the lamp holder 42 can be completely immersed in the inner cavity of the lamp cover 51. Figure 5 , Figure 6 As shown, the lamp tube 41 is completely sunken into the inner cavity of the lamp cover 51, and at least a part of the lamp holder 42 is located outside the lamp cover 51 to facilitate the installation, fixing and wiring of the ultraviolet lamp 4. Since the lamp holder 42 does not emit light, even outside the lamp cover 51, no ultraviolet rays will irradiate the outside of the host 3.

[0066] Specifically, Figure 4 As shown, the top of the lampshade 51 has an opening 512 for the lamp tube 41 to extend into the inner cavity, and protruding fixing columns 513 are provided on both sides of the opening 512. The lamp holder 42 is provided with fixing openings corresponding to the fixing columns 513, so that fasteners such as screws pass through the fixing openings and are fastened to the fixing columns 513 to achieve the installation of the ultraviolet lamp 4 and the lampshade 51. Of course, the lamp holder 42 can also be fixedly connected to the lampshade 51 in other ways, such as snap connection, threaded connection, etc., which are not limited here.

[0067] Furthermore, the lampshade 51 may be an integrally formed structure or may be Figure 4 The split-molded structure shown, that is, the lampshade is formed by the cooperation of a bracket and at least one baffle, is not limited here.

[0068] Embodiment 2: In this embodiment, as Figure 7 As shown, the blocking portion 5 includes an air collecting channel 34 arranged inside the main unit 3 and a lampshade 51 arranged at the inlet end of the air collecting channel 34. The lampshade 51 and the air collecting channel 34 enclose a housing cavity 35 for housing the ultraviolet lamp 4. The outlet of the air collecting channel 34 is connected to the air outlet 32.

[0069] The wind collecting channel 34 and the lampshade 51 cooperate to fully surround the ultraviolet lamp 4. The ultraviolet lamp 4 is located in the accommodating cavity 35. The channel wall of the wind collecting channel 34 and the lampshade 51 block the ultraviolet rays, thereby reducing the ultraviolet rays irradiated to the outside of the main unit 3. At the same time, the setting of the wind collecting channel 34 also improves the guiding effect on ozone, so that ozone flows quickly to the air outlet 32 ​​under the guidance of the wind collecting channel 34, thereby improving the flow efficiency of ozone, so that it flows more quickly and smoothly to the inside of the mixing cup 1, thereby improving the sterilization efficiency.

[0070] Specifically, Figure 7 As shown, the lampshade 51 has a top wall and a side wall extending downward, the air collecting channel 34 has a channel wall extending upward, and the lower edge of the side wall is lower than the upper edge of the channel wall, so that the two cooperate to form a accommodating cavity 35 for accommodating the ultraviolet lamp 4 and completely shield the surrounding side of the ultraviolet lamp 4.

[0071] like Figure 7 As shown, the bottom of the air collecting channel 34 is also provided with an air guiding section extending laterally to communicate with the air outlet 32 ​​.

[0072] Embodiment 3: In this embodiment, the blocking portion 5 is a baffle that blocks the ultraviolet lamp 4 and the side wall of the main unit 3.

[0073] The baffle can block the ultraviolet rays emitted laterally by the ultraviolet lamp 4, reducing the probability of ultraviolet rays irradiating to the outside through the housing of the host 3. Preferably, the baffle extends along the circumference of the host 3 to surround the ultraviolet lamp 4 by 360 degrees.

[0074] Embodiment 4: In this embodiment, the barrier portion 5 is an anti-ultraviolet coating coated on the inner wall surface of the main unit 3 or the installation groove 21.

[0075] By applying the coating, the structure and volume of the baffle 5 can be simplified, thereby reducing the space occupied by the baffle 5, saving the internal space of the host 3, and helping to reduce the volume of the host 3 and achieve miniaturization. Specifically, the anti-ultraviolet coating can be applied to the inner wall surface of the host 3, or to the inner wall surface of the installation groove 21, or to both the inner wall surface of the host 3 and the inner wall surface of the installation groove 21, which is not limited here.

[0076] The present invention does not limit the positional relationship between the ultraviolet lamp 4 and the mounting slot 21, which can be one of the following embodiments:

[0077] Implementation method 1: In this implementation method, Figure 1 As shown, after the host 3 is installed in place, the ultraviolet lamp 4 is completely sunk into the installation groove 21.

[0078] After the host 3 is installed in place, the ultraviolet lamp 4 is completely sunk into the installation groove 21, and the side groove walls of the installation groove 21 surround the ultraviolet lamp 4 in a circumferential direction, so that the side groove walls of the installation groove 21 can completely block the ultraviolet rays emitted laterally by the ultraviolet lamp 4 in the height direction, thereby improving the shielding effect of the groove walls of the installation groove 21 on ultraviolet rays.

[0079] Embodiment 2: In this embodiment, the ultraviolet lamp 4 includes a lamp tube, which is a straight tube vertically arranged on one side of the motor assembly 31. After the main unit 3 is installed in place, at least half of the lamp tube in the height direction extends into the installation groove 21.

[0080] The groove wall of the installation groove 21 blocks at least half of the lamp tube from bottom to top, and on the basis of having a good shielding effect on the ultraviolet rays irradiated by the ultraviolet lamp 4, the depth of the installation groove 21 can be reduced accordingly, thereby reducing the overall thickness of the cup cover 2, making the cup cover 2 lighter and more convenient for users to take. At the same time, the thinning of the cup cover 2 also makes the overall appearance of the meat grinder lighter and more beautiful, improving the visual experience of users.

[0081] In another embodiment, the ultraviolet lamp 4 includes a lamp tube, which is a curved tube arranged around the outer periphery of the motor assembly 31 .

[0082] The ultraviolet lamp 4 is a curved tube and is arranged around the motor assembly 31, which reasonably utilizes the space between the inner wall of the main unit 3 and the motor assembly 31, thereby optimizing the structural layout inside the main unit 3. At the same time, the curved tube structure extending circumferentially along the motor assembly 31 can also increase the length of the ultraviolet lamp 4 and the area covered by the ultraviolet lamp 4, thereby increasing the amount of ozone generated and improving the sterilization efficiency. In addition, the ultraviolet lamp 4 surrounds the outer periphery of the motor assembly 31, so that when the ultraviolet lamp 4 is turned on, ozone will be evenly produced on the peripheral side of the motor assembly 31, and then evenly enter the inside of the stirring cup 1 through the air outlet 32, and evenly distributed around the stirring cup 1, thereby improving the uniformity of the distribution of ozone in the stirring cup 1, ensuring the thoroughness of sterilization and disinfection, and avoiding the generation of sterilization dead corners that lead to bacterial residues.

[0083] The present invention does not limit the position of the communication port 22. In one embodiment, Figure 1 , Figure 2 As shown, the bottom wall of the main unit 3 is provided with an axial hole 33 through which the output shaft of the power supply assembly 31 is exposed, an air outlet 32 ​​is formed between the output shaft and the axial hole 33, and the connecting port 22 is a through hole for the stirring member 11 to pass through so as to be transmission-connected with the output shaft.

[0084] The shaft hole 33 on the bottom wall of the main unit 3 is used as the outlet of the output shaft, and forms an air outlet 32 ​​with the output shaft for discharging ozone in the main unit 3, so that the transmission connection between the main unit 3 and the stirring member 11, and the connection between the main unit 3 and the ozone in the stirring cup 1 share one opening, which reduces the number of openings on the bottom wall of the main unit 3, simplifies the structure of the main unit 3, and reduces the difficulty of processing. In addition, an anti-overflow structure for preventing food from overflowing from the stirring cup is provided at the through hole, and the air outlet 32 ​​is aligned with the connecting port 22 up and down. The anti-overflow structure can also prevent food from overflowing from the connecting port 22, and there is no need to set an additional anti-overflow structure at the air outlet 32.

[0085] In addition, since the shaft hole 33 and the connecting port 22 generally correspond to the center of the blending cup 1 , ozone will enter the blending cup 1 from the center of the blending cup 1 through the air outlet 32 ​​and then diffuse and flow around, thereby improving the uniformity of ozone distribution in the blending cup 1 .

[0086] In another embodiment, the cup cover 2 is provided with a through hole for the stirring member 11 to pass through and be transmission-connected to the motor assembly 31 , and the communication port 22 is staggered with the through hole.

[0087] The communication port 22 and the through hole are arranged in a staggered manner, and the opening position of the communication port 22 can be flexibly adjusted on the cup cover 2 according to the setting position of the ultraviolet lamp 4 and the spatial layout inside the main unit 3. This helps to shorten the air path length between the main unit 3 and the blending cup 1, reduce the kinetic energy loss of ozone during flow, and allow ozone to enter the blending cup 1 more quickly, thereby improving the sterilization efficiency.

[0088] As a preferred embodiment of the present invention, the cup cover 2 is recessed downward to form a mounting groove 21 , the bottom wall of the mounting groove 21 is lower than the mouth of the blending cup 1 , and the ultraviolet lamp 4 is at least partially sunk into the mouth of the blending cup 1 .

[0089] At least part of the ultraviolet lamp 4 is sunken into the mouth of the blending cup 1, so that the ultraviolet rays irradiated laterally outward by the ultraviolet lamp 4 are not only blocked by the outer shell of the main unit 3 and the wall of the installation groove 21, but also by the wall of the blending cup 1, thereby forming three shieldings for the laterally irradiated ultraviolet rays, thereby greatly reducing the ultraviolet rays irradiated to the outside of the blending cup 1, allowing the user to observe the food inside the blending cup 1 more clearly and reducing the impact of ultraviolet rays on the user's eyes.

[0090] Furthermore, a light shielding sleeve is provided on the mixing cup 1 at a position highly overlapping with the ultraviolet lamp.

[0091] The wall of the blending cup 1 is mostly made of glass or transparent plastic, which has poor light-shielding performance. By arranging a light-shielding sleeve on the portion where the blending cup 1 and the ultraviolet lamp 4 are highly overlapped, the portion has better light-shielding performance, thereby achieving a better shielding effect on the ultraviolet rays irradiated outward by the ultraviolet lamp 4.

[0092] Specifically, the light shielding cover can be only installed on the part where the blending cup 1 and the ultraviolet lamp 4 are highly overlapped, while the part where the blending cup 1 and the ultraviolet lamp 4 are not highly overlapped is not provided with the light shielding cover, so that the blending cup 1 still retains a part of the visible area, and the user can observe the food processing situation in the blending cup 1 through this area, thereby improving the user experience. In other embodiments, the light shielding cover can also be completely installed on the outside of the blending cup 1, so as to form a full shielding on the circumference of the blending cup 1, thereby improving the shielding effect of ultraviolet rays.

[0093] Preferably, if Figure 1 , Figure 8 As shown, the cup cover 2 further includes an outer cover body 24 extending outward from the top of the side wall of the mounting groove 21 to the mouth of the blending cup 1 , and the outer cover body 24 includes an annular wall 23 surrounding the outer side of the mounting groove 21 .

[0094] The annular wall 23 surrounds the outer circumference of the mounting groove 21, and serves as a third shielding against the ultraviolet rays irradiated laterally by the ultraviolet lamp 4. The ultraviolet rays are shielded from the inside to the outside by the outer shell of the main unit 3, the side wall of the mounting groove 21 and the annular wall 23 in sequence, and the light intensity gradually decreases, so that the user will not feel the glare from the outside, especially when using the meat grinder for a long time, and can obtain a better visual experience and usage experience.

[0095] like Figure 8 As shown, the top of the annular wall 23 and the notch of the mounting groove 21 are transitioned by an inclined surface or an arc surface, so as to make the appearance of the meat grinder more rounded and improve the appearance quality and aesthetics.

[0096] The parts not described in the present invention can be realized by adopting or drawing on the existing technology.

[0097] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0098] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
