Description

Effectual broken wall machine falls

Technical Field

The application relates to the field of food processing, in particular to a wall breaking machine with a complete double-layer structure and a noise reduction effect.

Background

The existing food processing machine, in particular to a wall breaking machine, generally relies on driving a crushing cutter to rotate at a high speed to realize cutting and crushing of food materials, and the wall breaking machine is easy to generate larger noise due to the processing conditions. The cup body part of the existing wall breaking machine is generally made of single-layer glass, and has the thickness of about 6mm and large weight. The weight of the cup body is increased after the cup body is filled with food materials, which is not beneficial to users to take the cup body and pour the food materials; when the glass cup body is used for processing hot drinks, the temperature of the cup wall rises along with the temperature of the slurry, and the risk of scalding a user exists when the user directly takes the glass cup body.

The existing solution is to set up the silence cover to come the lid with broken wall host computer or cup subassembly and close, forms inside confined cavity, and the noise that produces in the broken wall machining process seals in the sound-proof housing unable outside transmission, reaches the purpose of making an uproar falls. However, such a scheme needs to set up the silence cover that can cover the broken wall machine completely, and makes the volume of silence cover too big to silence cover and cup subassembly need be controlled alone respectively, have taken up too big space, still bring and control inconvenience.

In addition, some food processors are arranged, the cup body part adopts a double-layer cup body, and the double-layer cup body adopts a combination mode of a stainless steel inner cup body and a plastic cup body shell, so that the weight of the cup body can be reduced, high-temperature scalding is prevented, but the visual effect of food materials cannot be achieved, and the food or food materials with monitoring requirements on the processing process cannot be focused on in real time and dynamically. There are also some schemes of double-deck cup, directly set up seal structure in the position that cup rim of a cup or bottom of cup link to each other of cup and outer cup, seal structure is lasting to receive the influence of soaking of processing food material easily, still can receive the influence of heating in-process steam, and receive the influence of expend with heat and contract with cold between interior cup, outer cup, the sealing washer itself, especially when the shrink proportion is inconsistent, very easily make steam get into between the interior and exterior cup by seal position, influence the visual effect of cup, and seal structure receives the influence of expend with heat and contract with cold for a long time will accelerate its inefficacy.

In an earlier patent application, such as CN202121024698.2, a sealing-enabled food processor is disclosed, in which an interlayer is formed between the side wall of the inner cup and the side wall of the outer shell, and a sealing ring for sealing the interlayer is inserted into the interlayer from the exposed section after the inner cup is fitted and fixed. However, in such a scheme, the sealing ring is inserted into the sealing hole, so that the sealing installation position of the upper section of the inner cup and the outer shell cannot be provided with enough strength, otherwise, the sealing ring cannot be inserted better. The fixing between the inner cup and the outer shell depends more on the bottom fixed connection of the inner cup and the outer shell, so that the connection reliability of the inner cup and the outer shell is affected. Moreover, the insertion mounting mode cannot form a closed inner cavity better between the interlayers, and when the interlayers are heated and expanded, the sealing ring is applied with outward thrust, so that the sealing ring is easy to separate and lose efficacy; meanwhile, the bottom between the outer shell and the inner cup is in an open state, when the transparent cup is used, water or steam can enter the interlayer from the bottoms of the outer shell and the inner cup, and at the moment, water or steam residues exist on the inner wall of the interlayer of the transparent outer cup and the transparent inner cup, so that the appearance of the cup body is affected.

In other earlier patent applications, CN202221310280.2, for example, discloses a wall breaking machine with noise reduction, wherein the inner cup and the outer cup are sealed at the upper end by a sealing member, and when the stirring cup is mounted on the stand, the outer cup is in sealing connection with the stand and forms a closed cavity. However, in the scheme, the stirring cup is completely sealed by the machine base, so that the positioning and mounting precision between the stirring cup and the machine base is improved; and, the outer cup only wraps up the inner cup, although can be partly wrap up the outside noise parcel of transmission of inner cup, still have a large amount of noise to outwards transmit by unwrapped part, especially normally the outer cup can not wrap up the partial complete parcel below the inner cup rim of a cup completely, and can have local changeover portion, so, the changeover portion is when bearing vibrations and inside noise impact, can play the effect of local amplification for the stirring cup gathers transmission noise through the changeover portion, influences final noise reduction effect.

Of course, in other fields such as thermos cups, there are also products in which a completely double-layered cup is provided, and the cup is completely closed by a cup cover, so that the inside of the cup is completely isolated from the outside. But products such as thermos cups and the like mainly realize the aim of isolating heat conduction from the inside and the outside to realize heat preservation, are in a completely closed state no matter in the cup body or an interlayer of the cup body, and can not generate working states such as stirring processing and the like in the heat preservation process, and the internal environment is relatively stable. In the processing process of the food processor, the food materials are gradually heated, and the internal pressure of the stirring cup is gradually increased along with the temperature rise; meanwhile, in the crushing processing process, the food material is subjected to the action of the crushing knife to generate impact force, and the space and pressure change in the cup body assembly can be brought; furthermore, the food material can also generate foam and the like in the heating and boiling process, and the internal pressure can also change, so that the cup body component of the food processing machine is used for processing the food material, cannot be simply used as an appliance such as a vacuum cup and the like, and is arranged into a fully-closed double-layer cavity.

By adopting the technical scheme, the invention has the following beneficial effects:

1. according to the wall breaking machine, the cup body component adopts the double-layer cup, and compared with the existing single-layer glass, the thickness of the glass inner cup is reduced, so that the weight reduction of the cup body component is facilitated; due to the arrangement of the cup body shell, a user can be prevented from directly touching the glass inner cup, and the user can be prevented from being scalded easily when the glass inner cup is high in temperature; the upper segment of the glass inner cup is provided with a reducing part, the glass inner cup is divided into an upper segment cup body and a lower segment cup body through the reducing part, wherein the inner diameter of the upper segment cup body is larger than that of the lower segment cup body, so that the glass inner cup generates obvious inner diameter change at the reducing part, an installation step is formed on the outer side wall of the glass cup body, the upper end of the cup body shell is abutted to the installation step, an isolation interlayer is formed between the cup body shell and the glass inner cup, a sound insulation cavity can be formed by the isolation interlayer, noise transmitted by a smashing cutter set of the glass inner cup can be reduced, and working noise of a cooking machine is reduced. And the mounting step is directly formed by the outer side wall of the glass inner cup, so that the axial limit of the outer shell of the glass body can be realized, an additional limit structure can be omitted, and the mounting convenience and efficiency of the inner cup and the outer cup are improved. Utilize the bowl cover subassembly to stretch into upper segment cup for form the bowl cover intermediate layer between portion of stretching into and the glass in, so, after bowl cover subassembly and bowl cover subassembly are installed in place, both utilized the double-deck cup part that forms between glass in and the cup shell, still made between the upper segment cup of single-deck part and the bowl cover subassembly form the double-deck part that is located crushing space, guaranteed the continuation of the double-deck part of cup subassembly, and then guaranteed the whole noise reduction effect of cup subassembly. The visual cup body assembly of visual cup body shell and glass inner cup assembly can satisfy the visual demand of user to processing food material in the cup. Compared with the original internal steel and external plastic double-layer cup scheme, the closed space improves the noise reduction function, and the perspective cup body is easier to observe and control and is convenient to clean. Of course, compared with the existing glass, the noise reduction effect is improved on the premise that the inner glass can be guaranteed.

Furthermore, the inner diameter change generated by the reducing part is utilized to enable the extending part and the reducing part to form an isolation space, and the isolation space is also positioned in the crushing space and is formed by the cup body component and the cup cover component during assembly, so that the structure is simple. When the stirring cup is in the processing process, no matter in the crushing process or in the heating process, when the airflow in the crushing space moves upwards along the inner wall of the glass inner cup, the inner diameter is suddenly changed when the airflow reaches the position of the diameter-changing part, but most of the airflow still flows upwards along the original path under the self inertia effect and further flows to the extending part, and then flows back into the crushing space through the extending part, so that complete circulation is formed; a small part of air flow can flow into the isolation space to form local small circulation in the isolation space, the air pressure in the isolation space is higher than that of other parts, after the small circulation of the relative circulation is formed in the isolation space, a relatively closed space is formed in the crushing space to prevent other parts in the crushing space of the cup body assembly from exchanging with the isolation space, and then the isolation space is compared with other parts in the crushing space to form an isolation layer similar to a double-layer cup. Thus, the lower section part of the whole cup body component forms an isolation interlayer by the glass inner cup and the cup body shell, the upper section part forms a cup cover interlayer by the glass inner cup and the cup cover component, and the upper section part is connected between the isolation interlayer and the cup cover interlayer, so that a double-layer effect is formed by the isolation space, and the whole cup body component forms a finished double-layer effect. The cup body assembly has the advantages that the inner cup body and the outer cup body are not required to be provided with complete double-layer parts, and a sealing structure is not required to be arranged between the inner cup body and the outer cup body, particularly at the position of the crushing space part, so that the structure and the sealing requirement for the cup body assembly are simplified, and the whole double-layer effect of the cup body assembly can be achieved.

Furthermore, the reducing part generates space mutation in the crushing space, particularly local diameter mutation formed by the isolation space, and when noise is transmitted to the isolation space, noise energy is rapidly lost due to space mutation, so that the noise reduction effect is rapidly realized; the small circulation in the isolation space further drives the noise to continuously impact the loss in the small circulation, and further realizes noise reduction; in addition, the isolation space forms a relatively closed space, and the outward transmission of noise can be effectively reduced, so that multiple noise reduction effects are realized, and the aim of further noise reduction is fulfilled.

2. The reducing part comprises a transition section with gradually enlarged inner diameter from bottom to top, a continuous arc or curve transition is formed between the lower section cup body and the upper section cup body, the isolation space forms a same continuous transition surface along the inner wall of the transition section, when the airflow flows upwards along the inner wall of the glass inner cup, the airflow can smoothly flow upwards and form stable small circulation in the isolation space, and the small circulation is conveniently and rapidly formed and effectively isolated from the inside of the crushing space. Through the difference of the extending depth of the extending part of the cup cover assembly, for example, when the extending part is only positioned in the upper-section cup body and does not exceed the lower end of the upper-section cup body, the isolation space can be formed by the extending part, the inner wall of the upper-section cup body and the diameter-changing part in a surrounding manner; when the extending part reaches the lower end of the upper section cup body and even exceeds the lower end of the upper section cup body to be abutted against the transition section, the isolation space can be formed by the extending part and the inner wall of the filtering section in a matched mode. So set up, can all easily form to cup subassembly and bowl cover subassembly of difference to do not need bowl cover subassembly and cup subassembly to set up the cooperation size of enough accuracy, simple structure is easy.

3. Correspondingly, the reducing part can also be directly arranged into a step, the reducing part forms an inner cup step at the joint of the upper-section cup body and the lower-section cup body, and the length of the extending part is preferably smaller than that of the upper-section cup body, so that the bottom of the extending part and the inner walls of the inner cup step and the upper-section cup body jointly encircle to form an isolation space. The isolation space formed in this way is more outstanding in inner diameter change, and the influence on the noise reduction effect is correspondingly larger.

4. The sealing piece is further arranged between the outer side wall of the extending part and the glass inner cup, so that the effect of the cup cover interlayer can be ensured, the isolation effect between the isolation space and the cup cover interlayer can be ensured, and the isolation noise reduction effect can be effectively achieved.

5. The inner diameter of the inner cavity of the extending part is not larger than the inner diameter of the lower section cup body, so that the airflow flows upwards through the inner wall of the inner glass cup, gradually contracts upwards after reaching the cup cover cavity of the extending part through the isolation space, and does not continuously diffuse outwards, and finally flows back into the crushing space under the guiding action of the cup cover assembly to form a large circulation in the crushing space, so that the airflow and noise in the crushing space can be concentrated in the crushing space and consumed internally, and the airflow and noise cannot diffuse outwards.

6. A transverse section is further arranged at the bottom of the extending part, and the transverse section covers the inner wall of the lower section cup body in the radial direction. It is simply understood that, from the top view of the wall breaking machine, the projection of the inner wall at the connection part of the lower-stage cup body and the reducing part is different from the projection of the transverse stage. Therefore, when the air flow flows upwards along the lower section cup body, the air flow can actively impact with the transverse section, so that the air flow can be actively split, the energy flowing to each part is lost, the impact of the air flow on other parts is reduced, and the noise in the air flow is effectively reduced. The pressure of the small circulating air flow in the isolation space can be properly increased, stronger reaction force is generated on the air flow, and finally, the small circulation of the isolation space with larger pressure intensity is formed, so that the air flow in the crushing space is pushed to flow into the inner cavity of the cup cover more, and the large circulation in the crushing space is formed. Through adjusting and setting up the relation of the internal diameter of bowl cover inner chamber and hypomere cup internal diameter to the size relation of adjusting isolation space and the pressure value that is located isolation space's air current microcirculatory, with the demand of the cup subassembly that satisfies different space sizes and different effects, it is convenient and efficient to implement.

Preferably, the ratio of the radial dimension L1 to the radial dimension L2 is set to be 0.1 less than or equal to L1/L2 less than or equal to 1, if the ratio is too small, the influence of the transverse section on the airflow is too weak, the airflow flowing to the isolation air is relatively weak, the pressure of the small circulation of the airflow in the isolation space is reduced, and the noise reduction effect of the isolation space is reduced. If the proportional relation is set to be too large, too much airflow flows to the isolation space, although the pressure of the isolation space can be improved, the noise reduction effect of the isolation space is properly improved, the impact force received by the transverse section and the cup cover assembly is increased, meanwhile, the airflow distributed to the inner cavity of the cup cover is reduced, the noise reduction effect of the noise reduction part is reduced, and the large circulation effect in the crushing space is also influenced.

7. The height ratio of the upper section cup body to the lower section cup body ranges from 1/10 to 1/3. Because the reducing part and the isolation space are formed by virtue of air flow in the crushing space, if the height ratio is too small, the sizes of the isolation space and the cup cover interlayer are also influenced, and on the premise that the complete double-layer isolation of the cup body component cannot be realized, the noise reduction effect of the isolation space and the cup cover interlayer is also influenced; if the height ratio is too large, the food material may reach the position of the reducing part, or the upper cup occupies too much crushing space volume, and normal processing of the cup assembly is not utilized.

8. Utilize bowl cover and lower bowl cover to further surround at bowl cover part and form the bowl cover and keep apart the chamber for the top opening of cup subassembly is under the isolation effect of bowl cover subassembly, also can form the effect of double-deck cavity, further has crushing processing function's crushing space with the broken wall machine and keeps apart double-deck, and then optimizes the double-deck isolation noise reduction effect that promotes the broken wall machine.

9. Still further set up into isolation chamber and exhaust chamber with throwing the material lid, the exhaust chamber can guarantee the normal exhaust demand of smashing space and outside, and isolation chamber can guarantee to throw the material lid and keep apart to the bilayer of the material hole position of throwing of bowl cover, so set up for smash the space in the contact transition part with outside, all be in at least bilayer isolation state, the effect of making an uproar falls in the broken wall machine bilayer reaches extremely.

The bottom end of the extending portion 421 is provided with a transverse section 422, and the transverse section 422 is formed by extending outwards along the bottom end of the extending portion 421. The bottom outer side wall of the extending portion 421 is further provided with a sealing ring groove 423, and the cup cover assembly 103 further includes a sealing ring 44 disposed in the sealing ring groove 423.

When the cup cover assembly 103 is mounted on the cup body assembly 102, the extending portion 421 extends into the upper stage cup body 21, at this time, an isolation interlayer 30 is formed between the extending portion 421 and the inner wall of the upper stage cup body 21, preferably, the isolation interlayer 30 and the crushing space 107 are isolated from each other by the sealing ring 44, so that air flow and noise in the crushing space 107 are not transmitted outwards through the isolation interlayer 30.

Preferably, the extending length of the extending portion 421 in the axial direction is smaller than the length of the upper cup 21, so that an isolation space is formed between the lower end of the extending portion 421 and the inner wall of the upper cup 21, and the transition section 221 of the reducing section 22, and it should be noted that the isolation space is in a state in which the inner wall is completely open-communicated with the pulverizing space 107. Further, the inner diameter of the cup cover inner cavity 45 of the extending portion 421 is smaller than the inner diameter of the lower-stage cup 23, and in the radial direction (or the axial projection direction), the transverse section 422 covers the inner wall of the lower-stage cup 23 (refers to the inner wall at the connection between the lower-stage cup 23 and the reducing section 22, and not refers to the inner wall of all parts of the lower-stage cup 23).

As shown in fig. 4, when the wall breaking machine works normally, the gas and the steam generated by heating the food material in the breaking space 107 flow upward along the inner wall of the glass inner cup 2, when the gas flows through the lower cup 23 and passes through the reducing section 22, although the gas flow is not limited by the inner wall of the glass inner cup 2, the gas flow still extends upward along the original path under the action of inertia, and a small part of the gas diffuses outward into the isolation space, but because the isolation space is connected with the breaking space and the other parts are all closed surfaces, the gas flow continuously flows between the surfaces in the isolation space and finally forms local small circulation, when the ascending gas flow is continuously supplemented into the isolation space, the pressure in the isolation space is gradually increased, and the ascending gas flow is reversely pushed to prevent the gas flow from further increasing into the isolation space, and finally, a relatively stable small circulation gas flow is formed in the isolation space, so that a relatively independent isolation space capable of isolating the breaking space from the outside of the cup assembly is formed in the isolation space. In this way, although part of the outer part of the upper-stage cup body 21 is not wrapped by the cup body housing 3, the upper-stage cup body 21 forms the isolation interlayer 210 and the isolation space 220 inside respectively, so that an interlayer assembly connected with the external isolation interlayer is finally formed, and the whole cup body assembly 102 forms a double-layer effect. Moreover, the isolation interlayer 210 and the isolation space 220 are formed by combining the glass inner cup 2 and the cup cover assembly 103, when the cup cover assembly 103 is installed in place, a corresponding space is formed, and when the wall breaking machine does not work, after the cup cover assembly 103 is taken off, the corresponding isolation interlayer and the isolation space disappear, the cup body assembly is not required to be arranged, especially the structure is not required to be arranged, especially in the prior art, the sealing structure is required to be arranged at the joint of the top ends of the inner cup and the outer cup to realize sealing, and the sealing structure is close to the crushing space or is positioned in the crushing space, so that steam and water are easy to enter between the inner cup and the outer cup through the sealing structure, thereby influencing the normal work of the cup body assembly, and reducing the noise reduction effect of the double-layer cup.

The radial dimension (the distance between the inner wall of the protruding portion 421 and the inner wall of the lower cup 23 (which may be understood as the projection of both in the axial direction) is L1, and the radial dimension (the same as the L1 measurement method) of the lower cup 23 and the upper cup 21 is L2, preferably, 0.1+.l1/l2+.1. If the proportion relation is too small, the influence of the transverse section on the air flow is too weak, the air flow flowing to the isolation air is relatively weak, the pressure of the small circulation of the air flow in the isolation space is reduced, and the noise reduction effect of the isolation space is reduced. If the proportional relation is set to be too large, too much airflow flows to the isolation space, although the pressure of the isolation space can be improved, the noise reduction effect of the isolation space is properly improved, the impact force received by the transverse section and the cup cover assembly is increased, meanwhile, the airflow distributed to the inner cavity of the cup cover is reduced, the noise reduction effect of the noise reduction part is reduced, and the large circulation effect in the crushing space is also influenced.

The height of the upper cup 21 of the inner glass 2 is H1, and the height of the lower cup 23 is H2 (it should be noted that, because the variable diameter portion is smoothly connected with the inner walls of the upper cup and the lower cup, in actual products, the connection portion between the upper cup and the variable diameter portion, and the connection portion between the lower cup and the variable diameter portion may not be accurately determined, so that H1 and H2 cannot be accurately measured, at this time, only a position with obvious radial change between the two needs to be visually determined as the connection portion, and no accurate determination of the connection portion is necessary), preferably, 1/10 is less than or equal to H1/H2 is less than or equal to 1/3. Because the reducing part and the isolation space are formed by virtue of air flow in the crushing space, if the height ratio is too small, the sizes of the isolation space and the cup cover interlayer are also influenced, and on the premise that the complete double-layer isolation of the cup body component cannot be realized, the noise reduction effect of the isolation space and the cup cover interlayer is also influenced; if the height ratio is too large, the food material may reach the position of the reducing part, or the upper cup occupies too much crushing space volume, and normal processing of the cup assembly is not utilized.

The upper cup 41 and the lower cup cover 42 are fixedly connected in a sealing manner, and a cup cover isolation cavity 43 is formed in the cup cover assembly 103. When the cup cover assembly 103 is installed in place, the cup cover assembly shields the upper opening of the cup body assembly 102, and the cup cover isolation cavity 43 can isolate the upper end of the crushing space 107 in a double-layer manner.

The cup cover assembly 103 is provided with a feeding hole 46, a feeding cover 104 is arranged at the feeding cover 46, the feeding cover 104 comprises a feeding upper cover 51 and a feeding lower cover 52 which are mutually buckled, the feeding lower cover 52 comprises a first section 521 and a second section 522, and the inner diameter of a cavity of the second section 522 is larger than that of the first section 521. The interior of the first section 521 forms the exhaust chamber 54 and the interior of the second section 522 forms the isolation chamber 53. The bottom of the first section 521 is provided with a lower cover bottom plate 523, and a portion of the lower cover bottom plate 523 located outside is provided with a lower exhaust hole 524. The bottom surface of the feeding upper cover 51 is provided with a gas discharge ring 511, and the feeding upper cover 51 is provided with a gas outlet 512 in the gas discharge ring 511. After the feeding upper cover 51 and the feeding lower cover 52 are buckled, the exhaust ring 511 passes through the isolation cavity 53 and extends into the exhaust cavity 54. The exhaust ring 511 has an exhaust passage 55 formed therein.

As shown in fig. 7, when the wall breaking machine is in operation, the air flow in the breaking space enters the feeding cover from the lower air outlet 524, flows into the air outlet cavity 54, rises in the air outlet cavity 54, reaches the isolation cavity 53, and continuously gathers in the isolation cavity 53 due to the closed state of the isolation cavity 53, the pressure is increased, and the air flow is reversely pushed and prevented from flowing into the isolation cavity, so that the subsequent air flow returns to flow into the air outlet channel 55 after flowing into the air outlet cavity 54, and finally is discharged out of the breaking space through the air outlet 512. So set up, can form simultaneously and carry out the isolation chamber of space isolation to smashing the space in throwing material lid position, the bowl cover that combines the bowl cover again keeps apart the chamber to and the double-deck cavity structure of cup subassembly, realize wholly keeping apart the packing to whole processing cup module especially smashing the space, still have the technical problem that vibrations and noise transfer come out when avoiding the double-deck parcel of part. Meanwhile, the double-layer cavity structure utilizes the flowing of the gas to realize double-layer isolation and noise reduction effects, compared with a fixed sealing cavity, the flowing gas can play the role of an air curtain (the air curtain is arranged in the normal flowing direction of the gas and is used for blocking the flowing of the normal flowing air and noise transmission, and particularly the air curtain can generate crossed air vibration, so that the noise can be energy and the noise reduction effect is realized, and the air curtain is generally provided with a faster flow rate, can quickly decompose the normal air and can realize the noise reduction purpose), so that the active noise reduction purpose is realized by using the air flow, and the better noise reduction effect is realized.

In summary, the present application provides for the provision of a cup assembly comprising an inner glass and an outer cup shell, wherein the inner glass and the outer cup shell form an insulating interlayer; then, the cup cover interlayer is formed in the crushing space by utilizing the extending part and the glass inner cup; the extending part and the reducing part are further utilized to form an isolation space, so that double-layer isolation of the cup body assembly is realized on the premise that the cup body outer shell is not required to completely wrap the glass inner cup; particularly, the interlayer and the isolation space of the cup cover are formed by utilizing the space structure in the crushing space, so that the noise in the crushing space can be directly transmitted, and the aim and the effect of better noise reduction are realized; particularly, the isolation space is isolated by utilizing a structure to form local communicated space, so that an air curtain effect is formed, and a better isolation effect is formed by means of flowing air flow; the connecting sealing structure of the cup body shell and the glass inner cup is located on the outer side wall of the glass inner cup and is not located at the cup mouth, the situation that the sealing structure is arranged at the connecting end when the cup body shell completely wraps the glass inner cup is avoided, and the structure is more reliable.
