Background

Along with the improvement of living standard, various juicers continuously emerge, become the new pet of health preserving personage. One type of juice extractor (also called juice extractor) is used for extracting fruit and vegetable juice by adopting a squeezing principle, and the juice extractor comprises a main machine, a juice receiving container, a screw rod, an extrusion barrel assembly and an upper cover, wherein a motor is arranged in the main machine, the juice receiving container is connected to the upper part of the main machine, the screw rod is longitudinally arranged in the juice receiving container, the extrusion barrel assembly is arranged between the screw rod and the juice receiving container, the upper cover is arranged at an opening at the upper part of the juice receiving container, the extrusion barrel assembly is provided with a filtering hole, and the lower part of the juice receiving container is provided with a juice outlet channel and a residue outlet channel. The screw rod includes the screw rod body and screw shaft, is equipped with the spiral on the surface of the screw rod body, and screw shaft and motor shaft transmission are connected, form between screw rod and recipient and hold the space.

When needing to press juice, will press juice earlier materials such as fruit, vegetables cut into the cubic, then put into the extrusion section of thick bamboo subassembly with cubic material, the starter motor to drive the screw rod through the screw shaft and rotate, the spiral on the screw rod is sheared blocky fruit vegetables material into less fragment gradually and gets into and hold in the space. Under the axial propelling action of the screw, the materials gradually move downwards and are extruded, so that the fruit and vegetable materials are extruded to obtain juice, and the residual materials are changed into fruit residues. The squeezed juice enters the juice receiving container after being filtered by the filtering holes on the extruding cylinder component and flows out from the juice outlet channel at the lower part of the juice receiving container, and the residue is discharged out from the residue outlet channel at the lower part of the juice receiving container.

However, the juicer has the defects of overlarge external dimension, inconvenience in carrying and use when the juicer is used outdoors and the like, therefore, a portable juicer is invented, the lower part of the juicer is a juice receiving container for storing juice, the upper part of the juicer is a host with a motor, a screw rod and a juice squeezing barrel are arranged in the juice receiving container, the lower part of the juice squeezing barrel is a residue collecting barrel, a feeding channel communicated with the juice squeezing barrel is eccentrically arranged in the host, and a motor shaft in the host is in transmission connection with the screw rod. When needing to squeeze juice, put into a juice section of thick bamboo with cubic material through throwing the material passageway in, the starter motor drives the screw rod and rotates, and the material receives the shearing breakage and the extrusion of screw rod and produces fruit juice, and the fruit juice of squeezing out gets into and connects the juice container after the filtration of the filtration pore of squeezing a juice section of thick bamboo and stores, and the residue then gets into in the collection sediment bucket of lower part through the hole of slagging tap of a juice section of thick bamboo bottom.

Because the height of the whole machine is equal to the height of the juice receiving container and the host machine, on one hand, the height can be reduced, on the other hand, the juice receiving container plays a role in storing juice at the same time, and the residue collecting barrel for storing the fruit residues is positioned in the juice receiving container, so the overall dimension of the whole machine can be greatly reduced, and the juice receiving cup and the residue receiving cup which are independent do not need to be additionally configured, and the juice receiving cup is convenient to carry and use when going out. The patent with publication number CN209252391U discloses a portable juice machine, the opening of the juice receiving cup is detachably connected with the casing, fig. 4 and fig. 6 of the patent show that the juice receiving cup of the juice machine adopts close fit with the casing, after juice is continuously accumulated and flows upwards, if the user does not find in time, the juice is likely to permeate into the machine base and enter into the motor along the motor shaft, thereby causing the motor damage. Especially for this kind of portable stock machine, the user can usually hold the host computer casing outside and take the complete machine, and this patent discloses that the side at the motor is equipped with rechargeable battery and main control board, and the main control board sets up in motor one side, and the juice liquid level constantly rises and can gush into in the casing and invade the main control board for the short circuit of circuit even leaks electricity, influences user's safety in utilization.

Because of the limitation of the external dimension, the volume of the juice receiving container is not too large, when the juice in the juice receiving container is gradually increased, if the user does not pay attention to the state of the juice receiving container, the juice may spread upwards and enter the motor of the main machine, thereby affecting the safety of the motor, even the use safety of the user; and the squeezing component is arranged in the juice receiving container, so that the sight of a user is shielded, and the user cannot easily find the rising condition of the liquid level of juice, thereby continuously feeding and juicing. On the other hand, when the user stops to squeeze juice and takes off the host computer from receiving the juice container, the fruit juice that receives in the juice container can be followed the opening part and spilled out in a large number rapidly, and the user need handle a large amount of fruit juices that spill out to influence user experience.

Disclosure of Invention

The invention aims to provide a safe and portable juice machine, which can effectively prevent juice from entering a motor of a main machine to influence the safe use of the motor, and can prevent a large amount of juice from overflowing from an opening of a juice receiving container when the main machine is taken down, thereby improving the user experience of the juice machine in the use process.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a safe portable stock machine, including connecing the juice container, connect the host computer that connects juice container opening part and inside to have the motor, the extrusion subassembly is including the crowded juice section of thick bamboo that has the filtration gap, be located crowded juice section of thick bamboo and the surface has spiral screw rod, be equipped with the material passageway of throwing that communicates crowded juice section of thick bamboo on the host computer, the motor shaft is connected with the upper end transmission of screw rod, the below of crowded juice section of thick bamboo is equipped with the album sediment bucket, host computer and connecing the juice container between be equipped with and connect the safe passageway of juice container inner chamber intercommunication, it connects outside the juice container to connect the interior juice accessible safe passageway outflow of juice container.

Firstly, as a portable juice machine, the lower part of the invention is a juice receiving container for storing juice, a main machine with a motor is arranged at the opening of the juice receiving container, and a feeding channel is directly arranged on the main machine. That is to say, the height of the whole machine is that the juice receiving container is added with the main machine, thereby being capable of obviously reducing the height and the overall dimension of the whole machine and being convenient for carrying and using when going out.

In addition, the residue collecting barrel is arranged below the juice squeezing barrel, so that fruit residues squeezed out of juice in the juice squeezing barrel can directly enter the residue collecting barrel, on one hand, the rapid discharge of the fruit residues is facilitated, on the other hand, the residue collecting barrel is arranged in the juice receiving container, therefore, no extra space is occupied, the overall dimension of the whole machine is facilitated to be reduced, and the residue collecting barrel is prevented from being turned over.

Particularly, the safety channel communicated with the inner cavity of the juice receiving container is arranged between the main machine and the juice receiving container, so that the juice can flow out through the safety channel firstly when the juice in the juice receiving container overflows due to the carelessness of a user, and the juice is effectively prevented from entering the motor of the main machine. At this time, the user can clearly see the juice leaking from the safety channel, and then stop the machine rapidly to avoid the juice from leaking continuously. Since the safety channel is at least partially arranged around the main machine, i.e. the safety channel is similar to a ring of 'flood discharge channel' formed at the lower part of the main machine, the fruit juice rising in the juice receiving container can be discharged out rapidly through the safety channel.

It can be understood that, since the juice leaking out through the safety channel mainly plays a role of warning the user, the leakage amount is very small, and particularly, the liquid level of the juice in the juice receiving container is limited by the liquid flow channel, so that when the user takes off the main machine from the juice receiving container, a large amount of juice can not overflow outwards.

It should be noted that the height of the safety channel in the present invention refers to the height difference between the lowest part and the highest part of the liquid flow channel.

Preferably, the ratio of the height of the outlet from which the juice flows out of the safety channel to the height of the juice receiving container is not less than 80%.

It will be appreciated that as the juice in the juice receiving container gradually overflows and overflows through the safety channel, the juice must first flow outwardly through the lowermost outlet of the safety channel, and as the juice level continues to rise, the juice will begin to flow outwardly from the higher outlet of the safety channel. That is, the "opening" of the secure channel becomes larger. Therefore, the ratio of the height of the outlet of the safety channel which flows out to the height of the juice receiving container can be controlled to be not less than 80%, on one hand, the juice can flow out through the safety channel before overflowing upwards and entering the motor, so that the warning effect is achieved for users, the users can be guaranteed to have enough time to shut down the machine, and the like; on the other hand, the juice receiving container has enough available capacity, and the problem of capacity waste of the juice receiving container is avoided. When the ratio of the height of the outlet of the safety channel to the height of the juice receiving container is less than 80%, the actual utilization rate of the capacity of the juice receiving container is reduced, and then the juice is frequently leaked through the safety channel.

Preferably, the opening of the juice receiving container is in sleeved connection with the host, and the safety channel is formed at the sleeved connection position.

The opening of the juice receiving container is connected with the host in a sleeved mode, so that the host and the juice receiving container can be conveniently assembled and used. That is, through simple sleeving connection, the main machine can be quickly connected to the opening of the juice receiving container, and a safe channel can be formed at the same time.

Preferably, the clearance of the safety channel is e, and e is more than or equal to 0 and less than or equal to 0.5 mm.

The clearance e of the safety channel can be controlled within the following range, e is more than or equal to 0 and less than or equal to 0.5mm, so that the safety channel can effectively overflow fruit juice in time, a good warning effect is further achieved for a user, the fruit juice with the liquid level rising is prevented from entering the motor, and meanwhile, the operation table top is effectively prevented from being polluted due to the leakage of excessive fruit juice. When e is more than or equal to 0.5mm, a large amount of juice flows out of the safe channel to pollute the operation table; when e is less than or equal to 0, the gap of the safety channel is too small, the fruit juice in the juice receiving container is difficult to effectively flow out through the safety channel in time, and then the user is slow to warn, and when the fruit juice is not discharged through the safety channel, the liquid level of the fruit juice is easy to rise and enters the motor.

Preferably, the main machine comprises an outer shell and a base connected to the lower portion of the outer shell, the lower end of the base comprises a connecting end, and the main machine is detachably connected with the juice receiving container through the connecting end.

The main machine comprises a base at the lower part of the outer shell, so that the assembly of the main machine, particularly the assembly of the internal motor, is convenient. Especially, the lower extreme of base includes and connects the link of juice container detachable connection to be convenient for form annular connection surrounding edge at the host computer lower extreme, and then form with connecing juice container and cup joint, joint etc. multiple detachable connection structure.

Preferably, the connecting end is inserted into the opening of the juice receiving container; or the connecting end is connected with the opening of the juice receiving container through threads; or the connecting end is connected with the opening of the juice receiving container through a buckle or a rotary buckle.

When the connecting end is inserted into the opening of the juice receiving container, the detachable sleeving connection can be formed between the opening of the juice receiving container and the host machine, so that the structure is simplified, and the disassembly and the assembly are convenient; when the connecting end is connected with the opening of the juice receiving container through threads, firm detachable connection can be formed between the opening of the juice receiving container and the host machine, and positioning in the axial direction and the circumferential direction can be simultaneously formed between the juice receiving container and the host machine; when the connecting end is connected with the opening of the juice receiving container through a buckle or a turn buckle, the quick connection and disassembly between the connecting end and the juice receiving container can be realized, and the axial or circumferential positioning between the connecting end and the juice receiving container can also be realized.

Preferably, a reduced outer step is provided at the outer side of the connection end, and the safety channel comprises a longitudinal gap and an upper transverse gap formed between the outer step and the opening of the juice receiving container; or, an outer expanding inner step is arranged at the inner side of the opening of the juice receiving container, and the safety channel comprises a longitudinal gap and a lower transverse gap which are formed between the inner step and the connecting end; or, an outer step is arranged at the outer side of the connecting end, an inner step is arranged at the inner side of the opening of the juice receiving container, and the safety channel comprises a longitudinal gap, an upper transverse gap and a lower transverse gap which are formed between the inner step and the connecting end.

When the outer side of the connecting end is provided with the reduced outer step, the outer step of the connecting end can be matched in the opening of the juice receiving container, at the moment, a longitudinal gap can be formed between the outer side wall of the outer step and the inner side wall of the opening of the juice receiving container, and an upper transverse gap communicated with the longitudinal gap can be formed between the step at the root of the outer step and the edge of the opening of the juice receiving container. That is, the safety channel is an inverted L-shaped structure including a longitudinal gap through which the juice ascends step by step and an upper transverse gap through which the juice overflows uniformly and rapidly, and the outlet height of the safety channel is substantially the same. It can be understood that the longitudinal gap can limit the flow rate of the juice in the safety channel in unit time, so that the overflow of the juice can be uniformly seen through the opening of the whole juice receiving container while the overflow of the juice is controlled, and a warning effect on a user is ensured.

Similarly, an outward-expanding inner step can be arranged on the inner side of the opening of the juice receiving container, at the moment, a longitudinal gap can be formed between the inner side wall of the inner step and the outer side wall of the connecting end, and a lower transverse gap communicated with the longitudinal gap can be formed between the step at the root of the inner step and the end face of the connecting end. That is, the safety channel is an L-shaped structure including a longitudinal gap and a lower transverse gap, juice enters the longitudinal gap through the lower transverse gap, then gradually rises in the longitudinal gap, and finally rapidly and uniformly overflows outwards through the opening edge of the juice receiving container with basically the same height. It can be understood that the lower transverse gap can limit the flow rate of the juice in the safety channel in unit time, and the longitudinal gap can be properly increased, so that the juice can be ensured to slowly rise in the longitudinal gap and finally uniformly overflow while the overflow amount of the juice is controlled, and a warning effect on a user is ensured.

That is, the secure channel at this point is a zigzag structure including an upper transverse gap, a longitudinal gap, and a lower transverse gap. When the juice in the juice receiving container gradually rises to the opening, the juice firstly enters the longitudinal gap through the lower transverse gap, then gradually rises in the longitudinal gap, and finally uniformly and quickly overflows outwards through the upper transverse gap with basically the same height, so that the flow and the flow rate of the juice in the safety channel in unit time can be accurately controlled, the juice is ensured to slowly rise in the longitudinal gap, the overflow of the juice can be uniformly seen through the opening of the whole juice receiving container as much as possible, and the warning effect on a user is ensured.

Preferably, the surface of the connecting end matched with the opening of the juice receiving container is locally sunken to form the safe channel; or the surface of the opening of the juice receiving container matched with the connecting end is locally sunken to form the safe channel; or the surface of the connecting end is provided with a convex rib matched with the opening of the juice receiving container, and the convex rib enables the connecting end to be separated from the upper end of the side wall of the juice receiving container to form the safe channel; or the upper end of the side wall of the juice receiving container is provided with a convex rib matched with the connecting end, and the convex rib enables the connecting end and the opening of the juice receiving container to be separated to form the safe channel.

When we set local dent on the surface of the connecting end to form the safe channel, the surface of the other part of the connecting end and the opening of the juice receiving container can still keep good matching relationship, and the cross section size of the safe channel can be conveniently controlled by controlling the depth and width of the dent, so as to accurately control the flow speed, flow and other parameters of the juice in the safe channel. In particular, the recess can be arranged on the side facing the user, so that the user can find the leakage of the juice in time and stop the machine, thereby reducing the waste of the juice and the pollution to the operating platform to the maximum extent.

Certainly, we can also set a local recess on the inner surface of the opening of the juice receiving container to form the safety channel, which can keep the connection end and the opening of the juice receiving container in a good matching relationship, and conveniently control the parameters of the flow speed, the flow rate and the like of the juice in the safety channel by controlling the depth and the width of the recess.

Or, we can also set up and connect the juice container opening complex protruding muscle on the surface of link, like the same thing, can also set up and connect the juice container lateral wall upper end with link complex protruding muscle, ensure on the one hand link and connect the open-ended good cooperation of juice container, be favorable to reducing the link simultaneously and connect the open-ended fit area of juice container to avoid the assembly difficulty that causes because of shape, dimensional tolerance as far as possible. In particular, as a positioning requirement, at least 3 ribs are provided, which space the connecting end from the opening of the juice collecting container and form the safety channel between adjacent ribs.

Preferably, a liquid receiving ring is arranged on the outer side of the opening of the juice receiving container, the liquid receiving ring is at least partially arranged around the juice receiving container, and a liquid storage tank is formed by surrounding the liquid receiving ring and the outer side of the juice receiving container.

When fruit juice passes through the outside spill-over of escape way, connect the reservoir that liquid ring encloses to collect the fruit juice that spills over, avoid fruit juice to pollute operation mesa and whole juice container that connects, avoid the waste of fruit juice.

Preferably, the safety channel comprises a radial channel arranged on one side of the feeding channel, which is far away from the motor, and the radial channel penetrates through the outer side wall of the main machine; or the lower end of the feeding channel is locally expanded to form an auxiliary liquid storage cavity capable of containing fruit juice.

Of course, the lower end of the feeding channel can be partially expanded outwards, so that an auxiliary liquid storage cavity capable of containing juice is formed. When the fruit juice rises to the main machine in the juice receiving container, the fruit juice firstly enters the feeding channel with the opened upper end. Along with the continuous rising of juice liquid level, the juice can enter into supplementary stock solution intracavity. Because the horizontal size in supplementary stock solution chamber will throw the material passageway greatly more than, consequently, the fruit juice can rise at throwing the material passageway lower extreme faster, and in case get into supplementary stock solution intracavity, then the speed that the liquid level rises can reduce rapidly to give the user enough warning in back and the time of shut down, avoid getting into the fruit juice of throwing in the material passageway and get into inside the motor.

Therefore, the invention has the following beneficial effects: not only can effectively avoid the fruit juice from entering into the motor of the host computer and influencing the safe use of the motor, but also can avoid the overflow of a large amount of fruit juice from the opening of the juice receiving container when the host computer is taken down, thereby improving the user experience of the original juice machine in the use process.

Detailed Description

The invention is further described with reference to the following detailed description and accompanying drawings.

As shown in figure 1, a safe and portable juicer refers to a household juicer which adopts a physical squeezing mode to produce fruit and vegetable juice. The juice collecting device comprises a juice collecting container 1, a host machine 2 and an extrusion assembly, wherein the lower end of the host machine is connected to an opening in the upper part of the juice collecting container, a motor 22 is arranged in the host machine, and a feeding channel 23 for feeding materials is eccentrically arranged on the host machine. The squeezing assembly comprises a juice squeezing barrel 3 with a filtering gap, a screw rod 4 which is longitudinally arranged in the juice squeezing barrel and is provided with a spiral 41 on the surface, a squeezing gap 31 is arranged between the outer side of the screw rod and the juice squeezing barrel, the lower end of a feeding channel on the main machine is communicated with the juice squeezing barrel, and a motor shaft is in transmission connection with the upper end of the screw rod.

Furthermore, the lower part of the juice squeezing barrel is positioned in the juice receiving container in a suspended way, and a residue collecting barrel 5 for collecting the residue is arranged below the juice squeezing barrel.

When needing to squeeze juice, put into the material of throwing passageway upper end opening earlier with cubic material, the material gets into the upper portion in the extrusion clearance in the juice squeezing barrel, the starter motor, thereby drive the screw rod and rotate in order to cut broken material and tentatively form fruit juice, the screw rod continues to extrude and grinds the material and promote the material and move down, thereby squeeze out fruit juice, the fruit juice filters through filtering the gap after outflow juice squeezing barrel and gets into and connect the juice container in, and the pomace of squeezing out fruit juice then is by screw drive to the bottom in extrusion clearance, then get into in the collection sediment bucket of juice squeezing barrel below.

In addition, a safety channel 6 communicated with the inner cavity of the juice receiving container is arranged between the main machine and the juice receiving container, and the safety channel is at least partially arranged around the main machine, namely the safety channel extends along the circumferential direction of the main machine. In this way, the juice in the juice receiving container can flow out of the juice receiving container through the safe channel.

It can be understood that, when the user continuously feeds the materials without observing the state of the juice in the juice receiving container during the juice extraction, the juice in the juice receiving container overflows, and even the juice enters the inside of the motor of the main machine, which affects the safety of the motor.

The safety channel communicated with the inner cavity of the juice receiving container is arranged between the main machine and the juice receiving container, so that once the juice in the juice receiving container overflows due to the operation and use errors of a user, the juice can flow outwards through the safety channel, and the juice is effectively prevented from entering the motor of the main machine. At this time, the user can clearly see the juice leaking from the safety channel, and then stop the machine rapidly to avoid the juice from leaking continuously. That is to say, the fruit juice that leaks through the escape way can play the warning effect to the user, reminds the user in time to shut down. When the user stops the machine and takes the main machine off the juice receiving container, the situation that a large amount of juice overflows outwards can not happen.

In particular, the safety channel is arranged at least partially around the main body, i.e. the safety channel is similar to a ring of "flood channels" formed in the lower part of the main body, which facilitates the rapid escape of the juice rising in the juice receiving container through the safety channel.

Furthermore, the ratio of the height of the safety channel to the height of the main machine can be controlled between 1/18 and 1/10, so that the overflowing fruit juice can be prevented from leaking out in time through the safety channel, the lower end of the motor can be higher than the highest position of the liquid flow channel, and the overflowing fruit juice can be effectively prevented from entering the motor to affect the safety of the motor. When the ratio of the height of the safety channel to the height of the main machine is less than 1/18, the leakage speed of juice in the safety channel is affected, and the leaked juice may rise into the motor. When the ratio of the height of the safety channel to the height of the main machine is larger than 1/10, the highest position of the liquid flow channel is higher than the lower end of the motor, and at the moment, overflowing fruit juice is easy to overflow outwards through the safety channel and partially enter the interior of the motor at the same time, so that the safety of the motor is affected. In this embodiment, the height of the host is 140mm, and the height of the safe passage is 10 mm.

It should be noted that the height of the safety channel in this embodiment refers to the height difference between the lowest position and the highest position of the liquid flow channel.

It will be appreciated that the safety channel has an outlet for the juice, preferably such that the ratio of the height of the outlet for the juice from the safety channel to the height of the juice receiving container is not less than 80%. On the one hand, before the fruit juice in the fruit juice receiving container overflows upwards and enters the motor, the fruit juice flows outwards through the safety channel, so that a warning effect is achieved for a user, and the user is guaranteed to have enough time to shut down and the like. That is, there is enough time from the juice beginning to overflow through the safety channel to the juice continuing to rise to the lower end position of the motor, thereby ensuring to attract the attention of the user and taking measures such as stopping the machine in time. On the other hand, the juice receiving container has enough available capacity, and the problem of capacity waste of the juice receiving container is avoided.

As a preferred scheme, the opening of the juice receiving container and the host machine can form a sleeving connection, the safety channel is formed at the sleeving connection position, and the sleeving connection can not only enable the host machine to be quickly connected to the opening of the juice receiving container, but also form the safety channel, so that the host machine and the juice receiving container can be conveniently assembled and used.

Preferably, as shown in fig. 2, we can control the clearance e of the safety channel in the following range: e is more than or equal to 0 and less than or equal to 0.5mm, and in the embodiment, e is preferably 0.25mm, so that the safety channel can effectively overflow the juice outwards in time, a good warning effect is further provided for a user, the situation that the juice level rises too fast to enter the motor is avoided, and meanwhile, the situation that the operation table top is polluted due to the leakage of too much juice is effectively avoided.

As another preferred solution, as shown in fig. 1 and 3, the main body includes an outer housing 21 made of plastic and a base 24 connected to a lower portion of the outer housing, so as to facilitate assembly of the main body, especially assembly of the internal motor. The lower extreme of base then includes can with connecing the link 25 that the juice container is connected to be convenient for form annular connection surrounding edge under the host computer, and then form with connecing the juice container and cup joint, joint etc. multiple detachable connection structure, make things convenient for the host computer in the dismouting of connecing on the juice container.

The detachable connection between the connecting end and the juice receiving container can adopt various forms, and particularly, the connecting end can be inserted into an opening of the juice receiving container, so that the structure is simplified, and the disassembly and the assembly are convenient; or the connecting end can be connected with the opening of the juice receiving container through threads, so that the connection reliability between the juice receiving container and the main machine is improved, and the juice receiving container and the main machine can be positioned in the axial direction and the circumferential direction at the same time; certainly, the connecting end and the opening of the juice receiving container can be connected through a buckle or a turn buckle, so that the quick connection and disassembly and assembly between the connecting seat and the juice receiving container can be realized, and the axial or circumferential positioning between the connecting seat and the juice receiving container can also be realized.

Since the screw connection, the snap connection, the turn-buckle connection per se belong to the prior art, a detailed description is not given again.

Further, as shown in fig. 2, a reduced outer step 251 may be provided at the outer side of the connection end, when the main body is mounted at the opening of the juice receiving container, a longitudinal gap 61 may be formed between the outer side wall of the outer step of the connection end and the inner side wall of the opening of the juice receiving container, an upper transverse gap 62 communicated with the longitudinal gap may be formed between the step at the root of the outer step and the edge of the opening of the juice receiving container, the upper transverse gap and the longitudinal gap are connected in an inverted L shape, and the safety channel at this time includes the longitudinal gap and the upper transverse gap.

The juice gradually rising in the juice receiving container firstly gradually rises through the longitudinal gap and then uniformly and rapidly overflows outwards through the upper transverse gap. The longitudinal gap can limit the flow of the juice in the safety channel in unit time, and then the juice overflow amount is controlled, and simultaneously the overflow of the juice can be uniformly seen through the opening of the whole juice receiving container, so that the warning effect on a user is ensured.

Furthermore, as shown in fig. 4, an inner step 11 may be provided inside the opening of the juice receiving container, when the connecting end is connected to the inner step of the opening of the juice receiving container, a longitudinal gap may be formed between the outer side wall of the connecting end and the inner side wall of the inner step of the juice receiving container, a lower transverse gap 63 communicating with the longitudinal gap may be formed between the step of the root of the inner step and the lower end surface of the connecting end, the lower transverse gap and the longitudinal gap are connected in an L-shape, and the safety channel includes the longitudinal gap and the lower transverse gap.

The juice which gradually rises in the juice receiving container firstly enters the longitudinal gap through the lower transverse gap, then gradually rises in the longitudinal gap, and finally uniformly and quickly overflows outwards through the opening edge of the juice receiving container. It can be understood that the lower transverse gap can limit the flow rate of the juice in the safety channel in unit time, and the longitudinal gap can be properly increased, so that the juice can be ensured to slowly rise in the longitudinal gap and finally uniformly overflow while the overflow amount of the juice is controlled, and a warning effect on a user is ensured.

Certainly, as shown in fig. 5, we can also set a reduced outer step outside the connecting end, set an expanded inner step inside the opening of the juice receiving container, at this time, a longitudinal gap is formed between the outer side wall of the outer step and the inner side wall of the inner step, an upper transverse gap communicated with the longitudinal gap can be formed between the step of the outer step root and the edge of the opening of the juice receiving container, a lower transverse gap communicated with the longitudinal gap can be formed between the step of the inner step root and the end surface of the connecting end, the safety channel at this time includes the upper transverse gap, the longitudinal gap and the lower transverse gap, and the upper transverse gap, the longitudinal gap and the lower transverse gap are connected into a zigzag structure. When the fruit juice in the juice receiving container gradually rises to the opening, the fruit juice firstly enters the longitudinal gap through the lower transverse gap, then gradually rises in the longitudinal gap, and finally uniformly and quickly overflows outwards through the upper transverse gap, so that the flow and the flow rate of the fruit juice in the safety channel in unit time can be accurately controlled, the fruit juice is ensured to slowly rise in the longitudinal gap, the overflow of the fruit juice can be uniformly seen through the opening of the whole juice receiving container as much as possible, and the warning effect on a user is ensured.

As an alternative to the above-mentioned safety channel structure, as shown in FIG. 6, we can also form the safety channel by forming a local recess 64 on the surface of the connecting end that is matched with the opening of the juice receiving container. Not only can ensure that the part except the dent on the circumferential surface of the connecting end keeps good matching relation with the opening of the juice receiving container, but also can conveniently control the size of the cross section of the safety channel by controlling the depth and the width of the dent, thereby accurately controlling the parameters of the flow speed, the flow rate and the like of the juice in the safety channel. Preferably, the recess is disposed on the side facing the user, so that the user can find the juice leakage and stop the machine in time, thereby minimizing the waste of juice and the pollution to the operation platform.

Or, as shown in fig. 7, the surface of the opening of the juice receiving container matched with the connecting end is locally recessed to form the safety channel, so that the connecting end and the opening of the juice receiving container can keep a good matching relationship, and parameters such as flow speed, flow rate and the like of the juice in the safety channel can be conveniently controlled by controlling the depth and width of the recess.

As another alternative to the above-mentioned safe channel structure, as shown in FIGS. 8 and 9, we can also provide a rib 65 on the connecting end surface to match with the opening of the juice receiving container; or, a convex rib matched with the connecting end is arranged at the upper end of the side wall of the juice receiving container. That is, the connecting ends are matched with the juice receiving container and positioned mutually through the convex ribs. Preferably, 3 ribs are provided, which are distributed uniformly in the circumferential direction, in order to achieve a good centering between the connecting end and the juice collecting container. The convex ribs can separate the connecting end from the side wall of the juice receiving container, reduce the matching area of the connecting end and the opening of the juice receiving container and avoid the assembly difficulty caused by the shape and the size tolerance as much as possible. On the other hand, the safety channel may be formed between the connection end and the juice receiving container opening.

In order to avoid the contamination of the operation table top by juice leaking out through the safety channel, as shown in fig. 10, a liquid receiving ring 12 may be arranged outside the opening of the juice receiving container, the liquid receiving ring being arranged at least partially around the juice receiving container, so that a liquid storage tank 13 is enclosed between the liquid receiving ring and the outside of the juice receiving container.

When connecing the juice in the juice container excessive and outwards overflowing through the escape way, the reservoir can collect the juice that overflows, prevents that fruit juice from polluting operation mesa and whole juice container that connects, avoids the waste of fruit juice.

Finally, the safety channel may further include a radial channel 66 disposed on a side of the feeding channel away from the motor, the radial channel extending through an outer sidewall of the main machine. When the fruit juice rises gradually to the main frame in connecing the juice container in, can be through keeping away from the direct outside outflow of radial passageway on one side of the motor, avoid inside the fruit juice gets into the motor. That is, the radial channel at this time becomes the final safety guarantee.

Of course, the lower end of the feeding channel can be partially expanded outwards, so that an auxiliary liquid storage cavity capable of containing juice is formed. When the fruit juice rises to the main machine in the juice receiving container, the fruit juice firstly enters the feeding channel with the opened upper end. Along with the continuous rising of juice liquid level, the juice can enter into supplementary stock solution intracavity. Because the horizontal size in supplementary stock solution chamber will throw the material passageway greatly more than, consequently, the fruit juice can rise at throwing the material passageway lower extreme faster, and in case get into supplementary stock solution intracavity, then the speed that the liquid level rises can reduce rapidly to give the user enough warning in back and the time of shut down, avoid getting into the fruit juice of throwing in the material passageway and get into inside the motor.

It should be noted that the motor shaft at the lower end of the motor inside the main machine is in transmission connection with the upper end of the screw rod, that is, the motor is higher than the lowest end of the feeding channel, and the auxiliary liquid storage cavity is lower than the lower end of the motor. To effectively prevent juice from entering the interior of the motor.

Other embodiments of the present invention than the preferred embodiments described above will be apparent to those skilled in the art from the present invention, and various changes and modifications can be made therein without departing from the spirit of the present invention as defined in the appended claims.
