Description

TECHNICAL FIELD

[0001] The utility model relates to life electric appliance technical field, concretely relates to a kind of intelligent food processor. BACKGROUND

[0002] The existing food processor juicer, stock machine etc. Usually include the host computer of built-in motor and the juicing assembly arranged above the host computer, and the juicing assembly includes screw rod driven by motor and cutting knife arranged above screw rod in turn, and user puts fruit and vegetable food materials into the bunker when using stock machine, and rotates in juicing chamber with motor, and food materials are first pre-cut on cutting knife, and after cutting into small pieces, it moves downward through the dropping hole on the pressing plate, and then realizes extrusion in juicing chamber under the extrusion of screw rod to squeeze out juice. User finds that the juice yield of different types of fruits is quite different at the same speed, such as high-fiber fruits and vegetables such as celery, which need slower speed to realize sufficient juicing, and if the speed is higher, the juice yield will be greatly reduced; for example, grapes, apples and other fruits with rich pulp can achieve sufficient juicing at faster speed, and if the speed is slower, the juicing efficiency will be greatly reduced.

[0003] In order to solve the above problems, the applicant's prior application patent CN201520881529.9 discloses an intelligent juicer, which selects the juicing speed of the material according to the composition of the material, which can maximize the protection of the organization of each juicing material and fully release the nutritional ingredients of each fruit and vegetable material, so that the fruit juice made is not only nutritious, but also has the best taste. But user finds that the discharging speed of fruit and vegetable through the pressing plate mainly depends on the size of the dropping hole on the pressing plate, and the larger the dropping hole, the faster the discharging speed, which causes insufficient juicing of fruit and vegetable; and the smaller the dropping hole, the slower the discharging speed, which greatly reduces the juicing efficiency. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at providing an intelligent food processor, which can improve the juice yield of food materials while ensuring the juicing speed of the food processor.

[0005] In order to achieve the above purpose, the utility model provides an intelligent food processor, which includes the host computer of built-in motor and the juicing assembly arranged above the host computer, the motor is brushless motor, and the brushless motor has multiple speeds, the juicing assembly includes screw rod driven by brushless motor and cutting knife arranged above screw rod in turn, the pressing plate is provided with dropping hole, and the projection area S1 of dropping hole on horizontal plane and the projection area S2 of pressing plate on horizontal plane satisfy: 0.1≤S1 / S2≤0.3.

[0006] The present application sets a brushless motor in the food processor, and by virtue of the characteristics of the brushless motor, the noise of the motor rotation is lower when the user uses the food processor to process food materials, achieving the effect of noise reduction. At the same time, the brushless motor can realize frequency conversion control, so that the food processor can control the brushless motor to output different speeds according to different food materials and processing processes, so that the processing effect of the food materials is better and the processing is more sufficient, the taste of the processed food materials is improved, and the space occupied by the brushless motor is smaller, which helps to improve the compactness of the internal structure of the whole machine, greatly reducing the size of the brushless motor and the cup body in the axial direction.

[0007] At the same time, the pressing plate is provided with a blanking hole, so that after the user places the food materials in the juicing assembly, the whole fruit or large pieces of food materials are first pre-cut by the cutting knife, and the pretreated food materials move downward through the blanking hole and are further cut and pressed by the screw rod, realizing the processing of the food materials. The projection area S1 of the blanking hole on the horizontal plane and the projection area S2 of the pressing plate on the horizontal plane satisfy: 0.1≤S1 / S2≤0.3, which avoids the situation that the projection area of the blanking hole on the horizontal plane and the projection area of the pressing plate on the horizontal plane are less than 0.1, causing the food materials to be unable to move downward through the blanking hole in time, resulting in too small feeding speed, and further causing the juicing time process and low efficiency; at the same time, it avoids the situation that the projection area of the blanking hole on the horizontal plane and the projection area of the pressing plate on the horizontal plane are greater than 0.3, causing the food materials to move downward too fast, causing the screw rod to be unable to juice and causing too much food materials to accumulate near the screw rod, resulting in too much residue after juicing, and further causing the juice yield to be too low. Therefore, by setting the brushless motor and regulating the opening area of the blanking hole, the user can output different speed ranges for different food materials by the stepless speed regulation of the brushless motor, and cooperate with the opening area of the blanking hole to ensure the juicing speed while improving the juice yield of the food materials and improving the user experience.

Meanwhile, the main machine is provided with a control panel electrically connected with the brushless motor, the control panel is used for controlling the brushless motor to switch between the first speed range and the second speed range, realizing the control of the brushless motor, ensuring that the brushless motor can be infinitely switched in different speed ranges, and further ensuring the smooth processing of the food material.

Cooperate with the opening area of the material dropping hole, after the food material recognition module realizes accurate identification of the food material, control the brushless motor to output a specific speed, realize specific speed processing of specific food material, so that different food materials can pass through the material dropping hole at a suitable speed to continue processing, and the speed of the food material dropping through the material dropping hole can be controlled, further ensuring the juice extraction speed while improving the juice extraction rate of the food material.

[0012] In a preferred implementation manner of the intelligent food processor, the juicing assembly further comprises a speed detection module electrically connected with the control panel, the speed detection module is used for detecting the screw speed in real time and transmitting a signal to the control panel, and the control panel controls the brushless motor to switch to the first speed range or the second speed range according to the preset speed and the real-time speed.

[0013] By setting the juicing assembly to further include a rotating speed detection module electrically connected with the control board, when the user processes the food material, the rotating speed detection module can monitor the rotating speed of the screw rod in real time and transmit the monitored rotating speed to the control board in real time, the control board can compare the preset rotating speed with the real-time rotating speed, and then control the brushless motor to switch between the first rotating speed gear and the second rotating speed gear, so as to ensure the adaptability to different food materials, and then improve the juice yield while ensuring the juicing efficiency.

[0014] In a preferred implementation of the intelligent food processor, the main machine is further provided with a control display panel electrically connected with the control board, and the control display panel is provided with a plurality of food material type information units, and the control display panel is used to control the brushless motor to switch to the first rotating speed gear or the second rotating speed gear according to the selected food material type information.

[0015] By further providing the main machine with the control display panel electrically connected with the control board, and the control display panel is provided with a plurality of food material type information units, when the user adds food material into the juicing assembly, the user first selects the food material type information needed to be processed through the control display panel, and then the control display panel transmits the information to the control board, and the control board controls the brushless motor to output the first rotating speed or the second rotating speed according to the preset food material type information.

[0019] By arranging the stall detection module and configuring the stall detection module to detect whether the brushless motor is stalled in the first rotation direction and transmit a signal to the control board, if the food processing machine is stalled during processing of the food materials, the stall detection module can detect the stall information and transmit the information to the control board, and the control board can control the brushless motor to rotate an angle A in the second rotation direction to move the more food materials upward by a certain distance, so that the food materials near the screw are loosened, thereby reducing the resistance to the screw, and then the screw rotates in the first rotation direction to further process the food materials, remove the caked materials, effectively prevent the overall juicing efficiency from being affected due to the caked materials for a long time, and timely remove the caked materials outside to ensure the area of the screw in contact with the food materials, so that the food materials are sufficiently juiced to ensure the juicing rate of the food materials and improve the user experience.

[0020] In a preferred implementation of the intelligent food processing machine, the opening angle B of the material falling hole from the middle of the pressing plate to the outer periphery satisfies 60°≤B≤90°.

[0021] By arranging the opening angle B of the material falling hole from the middle of the pressing plate to the outer periphery to satisfy 60°≤B≤90°, the opening angle of the material falling hole is prevented from being too small or too large, so that the material falling hole is not too long in the radial or circumferential direction, the food materials cannot move downward in time through the material falling hole, the feeding speed is too small, and the juicing time is too long and the efficiency is too low, which helps to ensure the juicing rate of the food materials and improve the juicing efficiency.

[0034] In order to more clearly illustrate the overall concept of the present application, the following will be described in detail in an exemplary manner in conjunction with the accompanying drawings.

[0035] It should be noted that in the following description, many specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, therefore, the scope of protection of the present application is not limited by the specific embodiments disclosed below.

[0036] As shown in Figures 1 to 4 The present application provides an intelligent food processor, which comprises a main machine 1 with a built-in motor and a juicing assembly detachably arranged above the main machine 1, the motor is a brushless motor 2, and the brushless motor 2 has multiple rotational speeds, the juicing assembly comprises a screw 3 driven by the brushless motor 2 and a pressure plate 4 and a cutting knife 5 arranged above the screw 3 in sequence, the pressure plate 4 is provided with a blanking hole 41, and the projection area S1 of the blanking hole 41 on a horizontal plane and the projection area S2 of the pressure plate 4 on the horizontal plane satisfy: 0.1≤S1 / S2≤0.3, preferably, S1 is 1535mm 2 , S2 is 9803mm 2 ; or, S1 is 1798mm 2 , S2 is 12181mm 2More preferably, S1 / S2 = 0.1 or 0.2 or 0.3.

[0037] The present application sets a brushless motor 2 in the food processor, and by virtue of the characteristics of the brushless motor 2, the noise of the motor rotation is lower when the user uses the food processor to process food materials, achieving the effect of noise reduction. At the same time, the brushless motor 2 can realize variable frequency control, so that the food processor can control the brushless motor 2 to output different speeds according to different food materials and processing processes, so that the processing effect of the food materials is better and the processing is more sufficient, the taste of the processed food materials is improved, and the brushless motor 2 occupies less space, which helps to improve the compactness of the internal structure of the whole machine, greatly reducing the size of the brushless motor 2 and the cup body in the axial direction.

[0038] At the same time, the pressing plate 4 is provided with a discharging hole 41, so that after the user places the food materials in the juicing assembly, the whole fruit or large pieces of food materials are first pre-cut by the cutting knife 5, and the pretreated food materials move downward through the discharging hole 41 and are further cut and pressed by the screw rod 3, realizing the processing of the food materials. And the projection area S1 of the discharging hole 41 on the horizontal plane and the projection area S2 of the pressing plate 4 on the horizontal plane satisfy: 0.1≤S1 / S2≤0.3, which avoids the situation that the ratio of the projection area of the discharging hole 41 on the horizontal plane to the projection area of the pressing plate 4 on the horizontal plane is less than 0.1, causing the food materials to be unable to move downward through the discharging hole 41 in time, resulting in too small feeding speed, and further causing too long juicing time and too low efficiency. At the same time, it avoids the situation that the ratio of the projection area of the discharging hole 41 on the horizontal plane to the projection area of the pressing plate 4 on the horizontal plane is greater than 0.3, causing the food materials to move downward too fast, causing the screw rod 3 to be unable to juice in time and causing too much food materials to accumulate near the screw rod 3, resulting in too much residue after juicing, and further causing too low juice yield. Therefore, by setting the brushless motor 2 and standardizing the opening area of the discharging hole 41, the user can output different speed intervals for different food materials through the stepless speed regulation of the brushless motor 2, and cooperate with the opening area of the discharging hole 41 to ensure the juicing speed while improving the juice yield of the food materials, improving the user experience.

[0039] Specifically, the applicant has carried out multiple tests by changing the speed of the brushless motor 2 when the projection area S1 of the discharging hole 41 on the horizontal plane and the projection area S2 of the pressing plate 4 on the horizontal plane satisfy: 0.1≤S1 / S2≤0.3, and the following different figures express the changes of the juice yield and the juicing speed of the corresponding food materials with the speed of the brushless motor 2 under different speeds:

[0040] For example, Figure 5As shown, the juice yield and juicing speed of high-fiber ingredients, represented by celery, at different speeds (horizontal axis: speed of the brushless motor; vertical axis: juice yield of the ingredient on the left; vertical axis: juicing efficiency on the right). The graph shows that the left side has a speed lower than 25 r / min because the speed is too low, resulting in insufficient overall juicing efficiency and failing to meet the product's performance requirements. The right side is not selected because the juice yield decreases significantly, but the improvement in juicing efficiency is not significant. Therefore, only the intersection of the middle boxes is considered: the speed range for celery is set between 25 (±5) and 55 (±5) r / min. When the projected area S1 of the high-fiber ingredient at the discharge hole 41 on the horizontal plane and the projected area S2 of the pressure plate 4 on the horizontal plane satisfy 0.1 ≤ S1 / S2 ≤ 0.3, both high juice yield and high juicing efficiency are achieved.

[0041] like Figure 6 As shown in the figure, the juice yield and juicing speed of a relatively hard food, represented by carrots, at different speeds (horizontal axis: speed of the brushless motor; vertical axis: juice yield of the food on the left; vertical axis: juicing efficiency on the right). It can be seen from the figure that the speed on the left is lower than 25 r / min because the speed is too low, which will cause the overall juicing efficiency to fail to meet the requirements and not meet the performance requirements of the product itself. When the speed on the right is higher than about 50 r / min, the juice yield decreases significantly, but the improvement in juicing efficiency is not obvious. Therefore, considering both juice yield and juicing speed, the speed range of carrots is set between 25 (±5) and 50 (±5) r / min. When the projected area S1 of the material discharge hole 41 on the horizontal plane and the projected area S2 of the pressure plate 4 on the horizontal plane satisfy: 0.1≤S1 / S2≤0.3, both high juice yield and high juicing efficiency are achieved.

[0042] like Figure 7 As shown, the juice yield and juicing speed of juicy foods, represented by oranges, at different speeds (horizontal axis: speed of the brushless motor; vertical axis: juice yield of the food on the left; vertical axis: juicing efficiency on the right). The juice yield is not significantly affected by the speed (all within 3 percentage points). However, as the speed increases, the juicing speed increases linearly. The speed has little impact on the juice yield. Therefore, the speed can be set faster to ensure juicing efficiency. Taking all factors into consideration, the speed range for oranges and grapefruits is set between 65 (±5) and 85 (±5) r / min. When the projected area S1 of the discharge hole 41 on the horizontal plane and the projected area S2 of the pressure plate 4 on the horizontal plane satisfy: 0.1 ≤ S1 / S2 ≤ 0.3, both high juice yield and high juicing efficiency are achieved.

[0043] like Figure 8 , Figure 9The juice yield of the food materials represented by apples and cantaloupes, which are not greatly affected by the rotation speed, and the juicing speed (the horizontal axis represents the rotation speed of the brushless motor; the left vertical axis represents the juice yield of the food materials; and the right vertical axis represents the juicing efficiency) at different rotation speeds are shown in the figure. It can be seen from the figure that the juice yield is not obviously affected by the change in the rotation speed. Considering the juicing speed and the load, the intersection in the middle frame is selected, and the rotation speed range of the apples and cantaloupes is set to 30(±5)ˉ60(±5)r / min. When the projection area S1 of the food materials, which are not greatly affected by the rotation speed, on the horizontal plane of the material falling hole 41 and the projection area S2 of the pressing plate 4 on the horizontal plane satisfy 0.1≤S1 / S2≤0.3, both the juice yield and the juicing efficiency are high.

[0044] In summary, the optimal rotation speed range corresponding to each food material is obtained through experiments on a variety of food materials. When the user places different food materials in the juicing assembly, the brushless motor 2 can process the corresponding food materials according to the preset rotation speed corresponding to the different food materials, and cooperate with the opening area of the material falling hole 41 to ensure the juicing speed while improving the juice yield of the food materials and enhancing the user experience.

[0045] As a preferred embodiment of the present application, the brushless motor 2 has a first rotation speed gear and a second rotation speed gear, and the main machine 1 is provided with a control panel electrically connected with the brushless motor 2, which is used to control the brushless motor 2 to switch between the first rotation speed gear and the second rotation speed gear. It should be noted that the switching mode of the first rotation speed gear and the second rotation speed gear is not limited in the present application. It can be achieved by rotating a knob to different gears to switch between the first rotation speed gear and the second rotation speed gear, or by pressing different keys on the control panel to switch between different gears to control different rotation speeds.

[0046] By setting the brushless motor 2 with a first rotation speed gear and a second rotation speed gear, the brushless motor 2 can output different first rotation speeds and second rotation speeds through the first rotation speed gear and the second rotation speed gear to adapt to the different processing properties of different food materials. Meanwhile, under different rotation speed conditions, the brushless motor 2 cooperates with the opening area of the material falling hole 41 to make the food materials continue to be processed after passing through the material falling hole 41 at a suitable rotation speed, and also controls the speed of the food materials falling through the material falling hole 41 to improve the juice yield of the food materials while meeting the juicing speed. Meanwhile, the main machine 1 is provided with a control panel electrically connected with the brushless motor 2, which is used to control the brushless motor 2 to switch between the first rotation speed gear and the second rotation speed gear to control the brushless motor 2, ensure that the brushless motor 2 can be infinitely switched within different rotation speed ranges, and thus ensure the smooth processing of the food materials.

[0047] It should be noted that the present application does not make specific limitation on the rotation speed corresponding to the first rotation speed gear and the second rotation speed gear, and both of them do not limit to only one rotation speed, and both of them contain multiple rotation speed intervals, for example, the first rotation speed gear includes the aforementioned 25(±5)~55(±5) r / min for processing carrots and celery and the processing rotation speed interval 30(±5)~60(±5) r / min for apples, pears, watermelons and cantaloupes; the second rotation speed gear includes the aforementioned rotation speed interval 55(±5)~70(±5) r / min for processing grapes and the processing rotation speed interval 65(±5)~85(±5) r / min for oranges and pomelos, which will not be described here.

[0048] It should be noted that the present application does not make specific limitation on how the control board realizes the switching of the first rotation speed gear and the second rotation speed gear, which can be any one of the following embodiments:

[0049] Embodiment 1: In this embodiment, the juicing assembly further includes a food material recognition module electrically connected with the control board, the food material recognition module is used for identifying the type of food material and transmitting a signal to the control board, and the control board controls the brushless motor 2 to output the corresponding first rotation speed gear or second rotation speed gear.

[0050] By setting the food material recognition module, and the food material recognition module is used for identifying the type of food material and transmitting a signal to the control board, and the control board controls the brushless motor 2 to output the corresponding first rotation speed gear or second rotation speed gear, that is, after the user places the food material in the juicing assembly, the food material recognition module can identify the type of food material and transmit the food material type signal to the control board, and the control board can match the preset rotation speed interval of different types of food materials, so as to control the brushless motor 2 to output the corresponding first rotation speed or second rotation speed, cooperate with the opening area of the material falling hole 41, after the food material recognition module realizes accurate identification of the food material, the brushless motor 2 outputs a specific rotation speed, realizes specific rotation speed processing of specific food materials, so that different food materials can fall through the material falling hole 41 at their appropriate rotation speed to continue processing, and the speed of the food material falling through the material falling hole 41 can be controlled, further ensuring the juicing speed while improving the juice yield of the food material.

[0051] Specifically, when the food material recognition module identifies that the food material is apples, pears, watermelons, cantaloupes, etc., the control board controls the brushless motor 2 to switch to the first rotation speed gear and output the corresponding rotation speed; when the food material recognition module identifies that the food material is oranges, pomelos, etc., the control board controls the brushless motor 2 to switch to the second rotation speed gear and output the corresponding rotation speed

[0052] In this embodiment, the juicing assembly further comprises a rotation speed detection module electrically connected to the control panel, the rotation speed detection module is used for detecting the rotation speed of the screw rod 3 in real time and transmitting a signal to the control panel, and the control panel controls the brushless motor 2 to switch to the first rotation speed gear or the second rotation speed gear according to the preset rotation speed and the real-time rotation speed.

[0053] By arranging the juicing assembly to further comprise a rotation speed detection module electrically connected to the control panel, the rotation speed detection module can monitor the rotation speed of the screw rod 3 in real time when the user processes the food materials, and transmit the monitored rotation speed to the control panel in real time. The control panel can compare the preset rotation speed with the real-time rotation speed, and then control the brushless motor 2 to switch between the first rotation speed gear and the second rotation speed gear, so as to ensure the adaptability to different food materials, thereby improving the juice yield while ensuring the juicing efficiency.

[0054] Further, the first rotation speed gear is greater than the second rotation speed gear, the preset rotation speed of the brushless motor 2 is the first rotation speed gear, the real-time rotation speed is less than the preset rotation speed, and the control panel controls the brushless motor 2 to switch to the second rotation speed gear.

[0055] The first rotation speed gear is greater than the second rotation speed gear, the preset rotation speed of the brushless motor 2 is the first rotation speed gear, the real-time rotation speed is the preset rotation speed, and the control panel controls the brushless motor 2 to switch to the first rotation speed gear.

[0056] In this embodiment, the host 1 is further provided with a control display panel electrically connected to the control panel, and the control display panel is provided with a plurality of food material type information units. The control display panel is used for controlling the brushless motor 2 to switch to the first rotation speed gear or the second rotation speed gear according to the selected food material type information.

[0057] By arranging the host 1 to further comprise a control display panel electrically connected to the control panel, and arranging the control display panel to be provided with a plurality of food material type information units, the user can first select the food material type information to be processed through the control display panel after adding the food materials into the juicing assembly. Then, the control display panel transmits the information to the control panel, and the control panel controls the brushless motor 2 to output the first rotation speed or the second rotation speed according to the preset food material type information. In combination with the opening area of the material dropping hole 41, the control panel controls the brushless motor 2 to output a specific rotation speed after the user selects the food material to be processed, so as to realize the specific rotation speed processing of the specific food material. Therefore, different food materials can fall through the material dropping hole 41 at their suitable rotation speeds for further processing, and the speed of the food materials falling through the material dropping hole 41 can be controlled, thereby further improving the juicing speed while ensuring the juice yield of the food materials.

[0058] As a preferred embodiment of the present application, the brushless motor 2 comprises a first rotation direction and a second rotation direction, and the main machine 1 is provided with a control panel electrically connected with the brushless motor 2, and the control panel is used for controlling the brushless motor 2 to switch between the first rotation direction and the second rotation direction.

[0059] By setting the brushless motor 2 to comprise a first rotation direction and a second rotation direction, and the control panel is used for controlling the brushless motor 2 to switch between the first rotation direction and the second rotation direction, the brushless motor 2 can drive the screw rod 3 and the cutting knife 5 to realize forward rotation or reverse rotation. For example, when the first rotation direction is blocked, the second rotation direction is switched to unblock the slag, effectively preventing the overall juicing efficiency from being affected by long-term blockage, and the slag is discharged outside in time, ensuring the area of the screw rod 3 in contact with the food materials, so that the food materials are fully squeezed, thereby ensuring the juicing rate of the food materials, and further improving the juicing rate.

[0060] Further, the main machine 1 further comprises a stall detection module electrically connected with the control panel, and the stall detection module is used for detecting whether the brushless motor 2 is stalled in the first rotation direction and transmitting a signal to the control panel. When the brushless motor 2 is stalled, the control panel controls the brushless motor 2 to rotate an angle A in the second rotation direction. Specifically, A is selected from 60°-120°. After rotating the angle A in the second rotation direction, the first rotation direction is rotated again. If the first rotation direction is still blocked, the second rotation direction is rotated again, and the above operation is repeated 4-7 times. If it is still blocked, the food processor alarms to remind the user.

[0061] By setting the stall detection module, and the stall detection module is used for detecting whether the brushless motor 2 is stalled in the first rotation direction and transmitting a signal to the control panel, when the food processor processes the food materials, if the stall occurs, the stall detection module can detect the stall information and transmit the information to the control panel. The control panel can control the brushless motor 2 to rotate an angle A in the second rotation direction to move the more food materials upward by a certain distance, so that the food materials near the screw rod 3 are loose, thereby reducing the resistance to the screw rod 3. Then, the screw rod 3 rotates in the first rotation direction to realize further processing of the food materials, unblock the slag, effectively prevent the overall juicing efficiency from being affected by long-term blockage, and the slag is discharged outside in time, ensuring the area of the screw rod 3 in contact with the food materials, so that the food materials are fully squeezed, thereby ensuring the juicing rate of the food materials, and improving the user experience.

[0062] It should be noted that the structure of the material falling hole 41 is not limited in the present application. As a preferred embodiment of the present application, as shown in Figure 3 、 Figure 4 , the material falling hole 41 is provided with one and extends outward from the middle of the pressing plate 4 in a fan shape.

[0063] Further, as shown in Figure 4 The opening angle B of the blanking hole 41 from the middle of the pressing plate 4 to the outer periphery satisfies: 60°≤B≤90°.

[0064] By setting the opening angle B of the blanking hole 41 from the middle of the pressing plate 4 to the outer periphery to satisfy: 60°≤B≤90°, the opening angle of the blanking hole 41 is avoided to be too small or too large, which causes the blanking hole 41 to be relatively elongated in the radial or circumferential direction, so that the food material cannot pass through the blanking hole 41 downward in time, resulting in that the feeding speed is too small, and further causing that the juicing time process and efficiency are too low. It is helpful to ensure the juice yield of the food material and improve the juicing efficiency.

[0065] The technical scheme of the utility model is not limited to the above-mentioned embodiments, and it should be pointed out that the combination of the technical scheme of any one embodiment and the technical scheme of one or more other embodiments is within the protection scope of the utility model. Although the utility model has been described in detail by general description and specific embodiments in the foregoing, some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, these modifications or improvements made on the basis of not deviating from the spirit of the utility model are within the protection scope of the utility model.
