To this end, it is an object of the present invention to provide a sealing structure.

It is another object of the present invention to provide a food processor including the above-described sealing structure.

In order to achieve the above object, an embodiment of a first aspect of the present invention provides a sealing structure, including: the device comprises a base body, a first fixing piece and a second fixing piece, wherein a channel is arranged on the base body, and one end of the channel is opened; the sealing element comprises a mounting column, a sealing rib is arranged on the side wall of the mounting column, the sealing rib comprises a root part and an interference part, one end of the root part is connected with the side wall of the mounting column, the other end of the root part is separated from the mounting column and extends obliquely towards the end part of the first end of the mounting column and the outer side of the mounting column, and the interference part is arranged at one end of the root part, far away from the mounting column, and extends towards the direction far away from the root part along the extending direction of the root part; the sealing element can be inserted into the channel from the second end of the mounting column to the first end of the mounting column through the opening of the channel to seal the channel, when the sealing element seals the channel, the sealing rib is positioned in the channel, the root part extends from the mounting column to the side wall of the channel, and the interference part is tightly attached to the inner side wall of the channel; the mounting post increases in cross-sectional area from the second end of the mounting post to the first end of the mounting post.

According to an embodiment of the present invention, there is provided a seal structure including a base provided with a passage and having an opening at one end thereof, and a seal member for sealing the opening of the passage. When installed, the seal may be inserted into the passage through the opening of the passage from the second end, e.g., the front end, of the seal to the first end, e.g., the rear end, of the seal to effect a seal of the passage. Specifically, the sealing element comprises a mounting column and a sealing rib mounted on the mounting column, wherein the mounting column is used for mounting the sealing rib, and the sealing rib is specifically used for being attached to the inner side wall of the channel so as to seal the opening of the channel in the axial direction. The sealing rib comprises a root part and an interference part, one end of the root part is connected with the mounting column, the other end of the root part is separated from the mounting column and is obliquely and outwards arranged towards the end part of the first end of the mounting column, such as the tail part, namely, the root part is arranged on the mounting post in an inclined, backward and outward extending way, so that the front end of the root part is smaller, the rear end is larger, thereby realizing the guiding installation function through the root part when the installation column is installed in the channel, meanwhile, the smaller front end of the sealing element can also reduce the resistance of the sealing element during installation and disassembly so that the front end of the sealing element can be quickly and smoothly installed in the channel, and then just can improve the dismouting convenience of sealing member, like this at the occasion that the opening of passageway need seal repeatedly or open, just can greatly reduce the operation degree of difficulty to the passageway is sealed, improve the operation convenience that the passageway is sealed, and then can improve user experience. And the rear end of the sealing element is gradually thickened, so that the sealing element is more closely attached to the inner side wall of the channel, and the sealing performance of the product can be improved. And when the erection column was installed in the passageway, the root extended to the lateral wall laminating with the passageway from the erection column, and interfered portion continued extension outwards backward from the root, consequently, interfered portion when the normality, its size is greater than the size of passageway, consequently, when inserting the erection column in the passageway, interfered portion just can be under the extrusion of the inside wall of passageway, warp to the tip direction of the first end of erection column, and interfered portion warp the back backward, just can produce a resilience force, thereby interfered portion just can hug closely on the inside wall of passageway under the effect of this resilience force. Simultaneously, preferably, the sealing member inserts the installation to the passageway in back from the second end to the first end through the opening of passageway, interference portion hugs closely on the inside wall of passageway from the root to the first end of erection column is known deeply, after interference portion warp like this, interference portion can follow the root to the first end straight extension of erection column, interference portion warp the back promptly, can straighten successively and hug closely on the inner wall in the passageway, thereby interference portion warp the back and can also increase the cooperation area between its and the inside wall of passageway, thereby just can increase the sealing performance of sealing member through the deformation of interference portion, and then just can reliably seal the passageway. In addition, through setting up the interference portion, can also compensate the wearing and tearing of sealing member through the deformation of interference portion, this kind of setting is in the in-process that the sealing member was repeatedly pulled out and is installed promptly, and even there is wearing and tearing more just, nevertheless because interference portion itself just is compressed tightly by the lateral wall of passageway, consequently, slight wearing and tearing can not influence sealed the sealed of passageway, this application is through setting up the interference portion promptly, can further improve the life-span of sealing member to make the sealing member after long-time the use, still can have better sealing performance. In addition, the second end of the root of the sealing rib is separated from the side wall of the mounting column, so that a certain buffer space can be provided for the deformation of the sealing element, the deformation capacity of the sealing element can be enhanced, the sealing element can be more conveniently pulled out of or inserted into the channel, and the sealing element is very suitable for the channel which needs to be opened or closed frequently, such as a juice outlet nozzle on a vacuum food processor.

Preferably, the root portion and the interference portion both extend linearly along a linear direction, and of course, the root portion and the interference portion may not extend non-linearly along a linear direction, for example, the root portion and the interference portion extend in an arc line, that is, the edge of the sealing rib may also slightly tilt.

Wherein the cross-sectional area of the mounting post increases, preferably gradually increases, from the second end of the mounting post to the first end of the mounting post, which enables the mounting post to be configured with a gradually increasing configuration from the front to the back, i.e., which enables the first end of the seal to be relatively sharp, thereby facilitating the installation and removal of the seal.

In addition, the sealing structure provided according to the above embodiment of the present invention has the following additional technical features:

in the above technical solution, preferably, the number of the sealing ribs is plural, and the plurality of sealing ribs are arranged at intervals in the axial direction of the mounting column.

In these technical schemes, a plurality of positions of the side wall of the channel can be sealed by arranging a plurality of sealing ribs, so that the sealing performance can be improved. And a plurality of sealed muscle mutual interval sets up and can prevent mutual interference between a plurality of sealed muscle, therefore does benefit to the deformation of sealed muscle. Meanwhile, the number of the sealing ribs is multiple, so that when the sealing element is inserted into the channel from the second end to the first end, two adjacent sealing ribs and the side wall of the channel form a small closed cavity, and when the channel is a vacuum channel, the air pressure in the channel is smaller than the air pressure in the small cavity formed by two adjacent sealing ribs and the side wall of the channel, so that the air in the small cavity can apply a pressure on the interference part in the direction of the side wall of the channel, and the interference part can be further pressed on the side wall of the channel, and the sealing performance of the sealing element can be further improved.

In any of the above technical solutions, preferably, the lengths of the plurality of sealing ribs gradually increase from the second end of the mounting column to the first end of the mounting column.

In these solutions, when the sealing element is installed in the channel, since the first end of the sealing element is located outside the channel, when the sealing element is installed, the force applied to the first end of the sealing element is smaller than the force applied to the second end of the sealing element, and the lengths of the plurality of sealing ribs gradually increase, preferably gradually increase, from the second end of the mounting post to the first end of the mounting post, so that the sealing element can gradually increase from the second end to the first end, i.e. the first end of the sealing element can be made larger, and the first end of the sealing element is larger, so that the resilience thereof is enhanced, and the pressing force between the first end of the sealing element and the channel can be increased, so that the first end of the sealing element can also be tightly fitted with the channel.

In any one of the above technical solutions, preferably, the sealing rib is annularly disposed around a circumference of the mounting column.

In these technical scheme, thereby the sealing rib is the annular setting and can seal the peripheral perisporium of passageway, just so can improve sealing performance. Of course, in the principle of sealing the channel, the sealing rib may not be arranged annularly, in which case the sealing rib is only used for sealing a part of the side wall of the channel, and the other side walls may be sealed by arranging other structures on the mounting post or in other ways.

In any of the above technical solutions, preferably, the mounting column is a hollow column, and the wall thickness of the mounting column is t, wherein t is greater than or equal to 0.5mm and less than or equal to 3.5mm, or t is greater than or equal to 0.8mm and less than or equal to 2.5mm, or t is greater than or equal to 1.0mm and less than or equal to 2.0 mm.

In these technical scheme, the erection column is hollow post, can reduce the material quantity of sealing member on the one hand to reduce cost. On the other hand, the sealing element can be sleeved on other parts through the hollow column, and then the sealing element is installed in the channel through other parts. And when the erection column is hollow, the value range of the wall thickness t of the erection column is preferably more than or equal to 0.5mm and less than or equal to 3.5mm, because the wall thickness of the erection column is reasonable and moderate. Specifically, if the wall thickness of erection column is less than this value scope, can lead to the erection column too thin, and the erection column too thin can lead to the intensity of sealing member to reduce, and the life-span also reduces thereupon, but if the wall thickness of erection column is greater than this value scope, can lead to the erection column too thick, and the erection column too thick easily leads to the sealing member processing to shrink, and the compression effect is poor, when extravagant material, but sealed effect worsens.

Wherein, more preferably, the value range of the wall thickness t of the mounting column is more than or equal to 0.8mm and less than or equal to 2.5 mm.

Wherein, still more preferably, the value range of the wall thickness t of the mounting column is between more than or equal to 1.0mm and less than or equal to 2.0 mm.

In any one of the above aspects, preferably, the thickness of the sealing rib in the axial direction of the mounting post decreases from the root portion to the interference portion.

In these technical schemes, the thickness of the sealing rib is preferably gradually reduced from the root to the interference portion, so that the strength of the sealing rib is gradually weaker from inside to outside, the deformability of the sealing rib is gradually increased from the middle to the edge, the strength of the sealing element can be ensured through the root of the sealing rib, the deformability of the sealing element is ensured through the interference portion of the sealing rib, and the sealing capability of the sealing element can be ensured.

In any of the above technical solutions, preferably, the length of the interference portion in the extending direction of the root portion is a, where a is greater than or equal to 0.1mm and less than or equal to 2.5mm, a is greater than or equal to 0.3mm and less than or equal to 2.0mm, or a is greater than or equal to 0.5mm and less than or equal to 1.5 mm.

In these solutions, a represents the sealing interference amount between the sealing element and the inner sidewall of the channel, i.e. the value of the root portion protruding from the inner sidewall of the channel when the sealing element is in a normal state, i.e. when the sealing element is not deformed, i.e. the difference between the radius of the sealing element at the edge of the root portion and the radius of the channel when the sealing element is not deformed in a normal state. And through setting up a at the scope of more than or equal to 0.1mm less than or equal to 2.5mm for the length of interference portion is more moderate, therefore makes the sealing member can fully contact and compress tightly with the inside wall of passageway promptly, so as to ensure its sealing performance, makes the sealing member have better elasticity again, thereby makes the sealing member can conveniently carry out the dismouting.

Therefore, the value of the thickness b may be preferably selected according to the wall thickness t of the hollow column, for example, preferably greater than 0mm and less than or equal to 1.5 times the thickness of the mounting column, and more preferably, the value of the thickness b may be greater than 0.5 times the wall thickness of the mounting column and less than or equal to 1.0 times the wall thickness of the mounting column.

According to an embodiment of the present invention, there is provided a seal structure including a base 1 provided with a passage 12 and having one end of the passage 12 opened, and a seal member 2 for sealing the opening of the passage 12. When installed, the seal 2 may be inserted into the channel 12 through the opening of the channel 12 from a second end, such as a front end, of the seal 2 to a first end, such as a rear end, of the seal 2 to effect a seal of the channel 12. In particular, the seal 2 comprises a mounting post 22 and a sealing rib 24 mounted on the mounting post 22, wherein the mounting post 22 is adapted to enable mounting of the sealing rib 24, and the sealing rib 24 is adapted to engage with an inner side wall of the channel 12 in particular, to enable sealing of the opening of the channel 12 from the axial direction. The sealing rib 24 includes a root portion 242 and an interference portion 244, one end of the root portion 242 is connected to the mounting post 22, the other end is separated from the mounting post 22, and the root portion 242 is disposed obliquely outward toward the end portion, such as the tail portion, of the first end of the mounting post 22, that is, the root portion 242 is disposed obliquely upward and rearward and outward on the mounting post 22, so that the front end of the root portion 242 is smaller and the rear end is larger, when the mounting post 22 is mounted in the channel 12, the root portion 242 can perform a guiding mounting function, and at the same time, the smaller front end of the sealing member 2 can reduce resistance when the sealing member 2 is mounted and dismounted, so that the front end of the sealing member 2 can be rapidly and smoothly mounted in the channel 12, and further the convenience in dismounting the sealing member 2 can be improved, so that the difficulty in sealing the channel 12 can be greatly reduced when the opening of the channel 12 needs to be repeatedly sealed or opened, the operational convenience of sealing the passage 12 is improved, and thus the user experience can be improved. The rear end of the sealing element 2 is gradually thickened, so that the sealing element 2 is more closely attached to the inner side wall of the channel 12, and the sealing performance of the product can be improved. When the mounting post 22 is installed in the channel 12, the root portion 242 extends from the mounting post 22 to be in contact with the side wall of the channel 12, and the interference portion 244 extends from the root portion 242 to the rear and to the outside, so that the interference portion 244 is larger than the channel 12 in a normal state, and when the mounting post 22 is inserted into the channel 12, the interference portion 244 can be deformed toward the end portion of the first end of the mounting post 22 under the extrusion of the inner side wall of the channel 12, and after the interference portion 244 is deformed rearward, a resilient force can be generated, so that the interference portion 244 can be in contact with the inner side wall of the channel 12 under the resilient force. Meanwhile, after the sealing element 2 is inserted into the channel 12 from the second end to the first end through the opening of the channel 12, preferably, the interference portion 244 is deeply attached to the inner side wall of the channel 12 from the root portion 242 to the first end of the mounting post 22, so that after the interference portion 244 is deformed, the interference portion 244 can extend linearly from the root portion 242 to the first end of the mounting post 22, that is, after the interference portion 244 is deformed, the interference portion can be sequentially and straightly attached to the inner side wall of the channel 12, and therefore, after the interference portion 244 is deformed, the fitting area between the interference portion 244 and the inner side wall of the channel 12 can be increased, the sealing performance of the sealing element 2 can be increased through the deformation of the interference portion 244, and the channel 12 can be reliably sealed. In addition, through setting up interference portion 244, can also compensate the wearing and tearing of sealing member 2 through the deformation of interference portion 244, and this kind of setting is in the process of sealing member 2 repeatedly pulling out and installing, even if this kind of setting has more wearing and tearing sealing member 2, because interference portion 244 itself just is compressed tightly by the lateral wall of passageway 12, consequently, slight wearing and tearing do not influence sealed the sealed of passageway 12, this application is through setting up interference portion 244, can further improve the life-span of sealing member 2 to make sealing member 2 after long-time the use, still can have better sealing performance. Furthermore, the separation of the second end of the root portion 242 of the sealing rib 24 from the side wall of the mounting post 22 provides a certain buffer space for the deformation of the sealing member 2, so that the deformability of the sealing member 2 can be enhanced, so that the sealing member 2 can be more conveniently pulled out of or inserted into the channel 12, and thus is very suitable for the channel 12 which needs to be opened or closed frequently, such as the juice outlet 52 of the vacuum food processor.

It is preferable that the root portion 242 and the interference portion 244 both extend linearly in a linear direction, but the root portion 242 and the interference portion 244 may not extend non-linearly in a linear direction, for example, extend in an arc, that is, the edge of the sealing rib 24 may also be slightly raised.

Wherein the cross-sectional area of the mounting post 22 increases, preferably gradually increases, from the second end of the mounting post 22 to the first end of the mounting post 22, which enables the mounting post 22 to be configured to increase gradually from front to back, i.e., which enables the first end of the sealing member 2 to be relatively sharp, thereby facilitating the installation and removal of the sealing member 2.

In the above embodiment, preferably, as shown in fig. 1 to 3, 6 and 7, the number of the seal ribs 24 is plural, and the plural seal ribs 24 are provided at intervals from each other in the axial direction of the mounting post 22.

In these embodiments, the sealing performance can be improved by providing a plurality of sealing ribs 24 to seal a plurality of positions of the side wall of the passage 12. The plurality of sealing ribs 24 are spaced apart from each other to prevent the plurality of sealing ribs 24 from interfering with each other, thereby facilitating deformation of the sealing ribs 24. Meanwhile, the number of the sealing ribs 24 is plural, so that when the sealing member 2 is inserted into the channel 12 from the second end to the first end, two adjacent sealing ribs 24 can form a closed small cavity with the side wall of the channel 12, so that when the channel 12 is a vacuum channel 12, the air pressure in the channel 12 is smaller than the air pressure in the small cavity formed by two adjacent sealing ribs 24 and the side wall of the channel 12, so that the air in the small cavity can apply a pressure on the interference part 244 in the direction of the side wall of the channel 12, so that the interference part 244 can be further pressed against the side wall of the channel 12, and the sealing performance of the sealing member 2 can be further improved. Of course, as shown in fig. 4 and 5, the number of the sealing ribs 24 may be one.

In any of the above embodiments, preferably, as shown in fig. 1-3, 6 and 7, the length of the plurality of sealing ribs 24 increases from the second end of the mounting post 22 to the first end of the mounting post 22.

In these embodiments, when the sealing member 2 is installed in the channel 12, since the first end of the sealing member 2 is located outside the channel 12, when the sealing member 2 is installed, the force applied to the first end of the sealing member 2 is smaller than the force applied to the second end of the sealing member 2, and the length of the plurality of sealing ribs 24 gradually increases, preferably gradually increases, from the second end of the mounting post 22 to the first end of the mounting post 22, so that the sealing member 2 can gradually increase from the second end to the first end, that is, the first end of the sealing member 2 can be made larger, and the first end of the sealing member 2 is made larger, so that the resilience thereof is enhanced, and therefore, the pressing force between the first end of the sealing member 2 and the channel 12 can be increased, so that the first end of the sealing member 2 can also be tightly fitted with the channel 12.

In any of the above embodiments, preferably, as shown in fig. 1 to 7, the sealing rib 24 is annularly provided around the circumference of the mounting post 22.

In these embodiments, the sealing rib 24 is provided in a ring shape so as to seal the peripheral wall of the passage 12, which improves the sealing performance. Of course, in the principle of sealing the channel 12, the sealing rib 24 may not be disposed annularly, in which case the sealing rib 24 is only used for sealing a portion of the sidewall of the channel 12, and the other sidewall may be sealed by providing other structures or other means on the mounting post 22.

In any of the above embodiments, preferably, as shown in FIGS. 1-7, the mounting post 22 is a hollow post, and the wall thickness of the mounting post 22 is t, wherein t is 0.5mm ≦ 3.5mm, or 0.8mm ≦ t ≦ 2.5mm, or 1.0mm ≦ t ≦ 2.0 mm.

In these embodiments, the mounting post 22 is a hollow post, which can reduce the material usage of the sealing member 2 to reduce the cost. On the other hand, the sealing element 2 can be sleeved on other parts through a hollow column, and then the sealing element 2 is installed in the channel 12 through other parts. When the mounting post 22 is a hollow post, the range of the wall thickness t of the mounting post 22 is preferably greater than or equal to 0.5mm and less than or equal to 3.5mm, because the wall thickness of the mounting post 22 is reasonably moderate. Specifically, if the wall thickness of the mounting post 22 is smaller than the value range, the mounting post 22 is too thin, and the strength of the sealing element 2 is reduced due to the too thin mounting post 22, and the service life is also reduced, but if the wall thickness of the mounting post 22 is larger than the value range, the mounting post 22 is too thick, and the sealing element 2 is easily processed and shrunk due to the too thick mounting post 22, so that the compression effect is poor, the material is wasted, and the sealing effect is poor.

Wherein, more preferably, the range of the wall thickness t of the mounting post 22 is greater than or equal to 0.8mm and less than or equal to 2.5 mm.

Wherein, more preferably, the range of the wall thickness t of the mounting post 22 is greater than or equal to 1.0mm and less than or equal to 2.0 mm.

In any of the above embodiments, preferably, as shown in fig. 1 to 7, the thickness of the seal rib 24 in the axial direction of the mounting post 22 decreases from the root portion 242 to the interference portion 244.
