Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and more specifically, to a sealing structure. Furthermore, this utility model also relates to a capsule cup including the aforementioned sealing structure. Background Technology

[0002] Sealing structures are widely used as common sealing structures. The most common sealing structure is the O-ring structure. However, in components that need to move up and down, such as the pressure chamber of a capsule cup, the traditional O-ring seal structure must have a large initial compression to ensure the seal when pressed down. This results in huge resistance when pulled up. Therefore, the traditional O-ring seal structure does not meet the different requirements of sealing and friction for different directions of movement.

[0003] In summary, how to solve the problem of the different requirements of sealing structure for sealing and friction in different directions of movement is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a sealing structure that produces different deformations when the sealing structure moves in different directions, so as to satisfy its sealing and easy sliding purposes.

[0005] Another objective of this invention is to provide a capsule cup that includes the aforementioned sealing structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A sealing ring sealing structure for achieving a seal between two relatively sliding workpieces, comprising:

[0008] The body comprises a main body and two workpieces. The main body is made of a material with elastic deformation function and has a ring structure. The main body includes at least two contact end faces. One contact end face of the main body is used to fix it to one of the workpieces. The other contact end face of the main body has a non-zero included angle with the sliding contact surface of the other workpiece.

[0009] Furthermore, the main body includes a first contact surface and a second contact surface. The main body is fixed to one of the workpieces via the first contact surface. The second contact surface consists of at least two inclined surfaces with different inclination angles, each of which contacts and seals with the other workpiece at a different angle.

[0010] Furthermore, the second contact surface end face includes a first inclined surface and a second inclined surface, and both the first inclined surface and the second inclined surface are arranged at different preset non-zero included angles with the sliding contact surface of another workpiece.

[0011] Furthermore, in this invention, the angle between the first inclined surface and the sliding contact surface of the other workpiece is smaller than the angle between the second inclined surface and the sliding contact surface of the other workpiece, and the second inclined surface and the sliding contact surface of the other workpiece are not parallel.

[0012] Furthermore, the main body is provided with a buffer groove, which is located at the connection line between the second inclined surface and the main body.

[0013] Furthermore, the buffer groove of this utility model is composed of a first buffer surface and a second buffer surface. The first buffer surface is an arc surface with an opening facing away from the body, and the second buffer surface is a plane and forms a preset angle with the end face of the first contact surface.

[0014] Furthermore, in this invention, the angle between the second buffer surface and the end face of the first contact surface is an acute angle.

[0015] A capsule cup comprising the sealing ring sealing structure described in any one of the preceding claims.

[0016] Furthermore, the present invention also includes two workpieces comprising a pressure chamber and a water holding chamber, wherein the water holding chamber is sleeved outside the pressure chamber;

[0017] The main body is a sealing ring, which is installed in the pressure chamber. The first contact surface end face contacts the outer wall of the pressure chamber, and the second contact surface end face contacts the inner wall of the water holding chamber.

[0018] Furthermore, the present invention provides an installation protrusion on the pressure chamber and an installation groove on the main body. When the installation protrusion is placed in the installation groove, the main body is installed on the pressure chamber.

[0019] The sealing structure provided by this utility model is used by installing the main body onto one of the workpieces. Its elastic deformation function increases the fit with the workpiece. The main body includes at least two end faces. The main body is fixed to the first workpiece via one end face, allowing it to move with the first workpiece to achieve relative sliding between the main body and the second workpiece. The other end face of the main body has a non-zero angle with the sliding contact surface of the second workpiece. When the main body moves with the first workpiece, due to the angle between the end face of the sealing structure and the sliding contact surface of the second workpiece, the friction between the end face of the main body and the sliding contact surface of the second workpiece increases when the main body slides towards the angle. This causes the end face of the main body to deform away from the angle, increasing the area of ​​the sliding contact surface between the sealing structure and the second workpiece. Simultaneously, it compresses the contact force between the sealing structure and the first workpiece, thus achieving a seal between the two workpieces. When moving towards the side away from the angle, the end face of the main body does not undergo compressive deformation, thus reducing the force required to move in this direction.

[0020] This utility model also provides a capsule cup including the above-mentioned sealing structure, which has the above-mentioned beneficial effects. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The core of this utility model is to provide a sealing structure that produces different deformations when the sealing structure moves in different directions, so as to satisfy its sealing and easy sliding purposes.

[0030] Another key aspect of this invention is providing a capsule cup that includes the aforementioned sealing structure.

[0031] Please refer to Figure 4 A sealing structure for achieving a seal between two relatively sliding workpieces includes: a body 1 and two workpieces, wherein the body 1 is an elastically deformable material part, the body 1 includes at least two end faces, one end face of the body 1 is used to fix with one of the workpieces, and the other end face of the body 1 has a non-zero included angle with the sliding contact surface of the other workpiece.

[0032] It should be noted that in the embodiments of this utility model, the main body 1 can be made of commonly used sealing materials such as rubber and silicone, and is manufactured by an integrated molding method.

[0033] Optionally, in some embodiments, the shape of the body 1 is similar to that of the capsule cup, and it may be a ring with a circular, rectangular or polygonal structure.

[0034] Optionally, in some embodiments, at least one of the first end face 4 and the second end face 2 is an inclined surface that is tilted toward the side away from the body 1, so that after the body 1 is installed on the capsule cup, there is a certain angle between its second end face 2 and the installation position, so that when it moves, different compression deformation will occur due to the existence of the tilt angle.

[0035] Optionally, in some embodiments, the tilt angle can be determined according to actual usage requirements, preferably less than 45 degrees.

[0036] In use, the body 1 is installed on one of the workpieces. Its elastic deformation function increases the fit with the workpiece. The body 1 includes at least two end faces. The body 1 is fixed to the first workpiece through one end face, so the body 1 can move with the first workpiece to achieve relative sliding between the body 1 and the second workpiece. The other end face of the body 1 has a non-zero angle with the sliding contact surface of the second workpiece. When the body 1 moves with the first workpiece, since there is an angle between the end face of the sealing structure and the sliding contact surface of the second workpiece, when the body 1 slides in the direction of the angle, the friction between the end face of the body 1 and the sliding contact surface of the second workpiece increases, causing the end face of the body 1 to deform away from the angle. This increases the area of ​​the sliding contact surface between the sealing structure and the second workpiece, and also compresses the contact force between the sealing structure and the first workpiece, thereby achieving a seal between the two workpieces. When moving towards the side away from the angle, the end face of the body 1 will not undergo compression deformation, thus reducing the force required to move in this direction.

[0037] Please refer to Figure 4 In some embodiments, the body 1 includes a first end face 4 and a second end face 2. The body 1 is fixed to one of the workpieces via the first end face 4. The second end face 2 includes at least two inclined surfaces with different inclination angles, both of which are used to contact and seal with the other workpiece. That is, the second end face 2 is used as an inclined surface and is the sliding end face of the capsule cup at the usage position. The second end face 2 is composed of at least two inclined surfaces with different inclination angles. Specifically, the inclined surface is divided into at least two segments, and each segment has a different inclination angle. Therefore, the inclined surface can adapt to more inclined surfaces with different inclination angles, which is beneficial to increasing its sliding sealing performance.

[0038] In the above embodiments, at least one of the inclined surfaces with the same inclination angle as the end face of the capsule cup is inclined at the same angle. This is beneficial to increase the end area of ​​the sealing structure and the end face when in use. At the same time, when it moves to the side away from the inclined direction of the inclined surface, it can increase the effect of the body 1 being squeezed and deformed by the friction between it and the end face, thereby further improving its sealing performance.

[0039] Optionally, in some embodiments, the second end face 2 includes a first inclined surface 201 and a second inclined surface 202. That is, the inclined surface of the second end face 2 of the body 1 is composed of two inclined surfaces, and its cross-section is composed of two edge lines with different inclination angles, as shown in the attached figure. Figure 3 As shown.

[0040] In the above embodiment, the first inclined surface 201 and the second inclined surface 202 are both arranged at a preset angle with the first end face 4. Specifically, the preset angle can be selected according to the position of the capsule cup. The first inclined surface 201 is provided with an angle between it and the end face of the capsule cup, while the second inclined surface 202 is kept parallel to the end face of the capsule cup to increase its end area.

[0041] In the above embodiment, the first inclined surface 201 is located above the second inclined surface 202. When the body 1 slides upward between itself and the end face of the capsule cup, the friction of the first inclined surface 201 is reduced due to its inclined angle. When the body 1 slides downward between itself and the end face of the capsule cup, the friction between the second inclined surface 202 and the end face of the capsule cup causes the first inclined surface 201 to generate an upward bending preload, thereby increasing the compressive force between the body 1 and the end face of the capsule cup, thus improving the sealing performance. At the same time, the inclined surface ensures that the deformation direction of the body 1 is opposite when it slides in two different directions, thereby ensuring that the force required to move in two directions is different, which is convenient for the user.

[0042] In other embodiments, the inclined surface is a conical structure, that is, the outer surface of the body 1 is conical or frustum-shaped, which can also realize that the body 1 requires different forces when moving in two directions, while meeting the sealing requirements.

[0043] In other embodiments, the angle between the first inclined surface 201 and the first end face 4 is greater than the angle between the second inclined surface 202 and the first end face 4. Specifically, the angle between the first inclined surface 201 and the end face of the capsule cup is smaller than the angle between the second inclined surface 202 and the end face of the capsule cup, thereby causing the body 1 to deform in different directions when sliding.

[0044] In the above embodiment, the angle between the second inclined surface 202 and the end face of the capsule cup is an acute angle. Therefore, when the body 1 and the end face of the capsule cup slide downward, the first inclined surface 201 will bend to a certain extent. At this time, the second inclined surface 202 and the end face of the capsule cup are parallel, thereby increasing the front end area of ​​the body 1 and the end face of the capsule cup, which is beneficial to improving its sealing performance.

[0045] Please refer to Figure 4In some embodiments, the body 1 is provided with a buffer groove 3. The buffer groove 3 is located at the bottom of the body 1 and on the side that is inclined away from the sealing surface. That is, the buffer groove 3 is provided at the bottom of the body 1. Specifically, the buffer groove 3 is located on the side where the body 1 moves into the capsule cup. Therefore, when the body 1 moves upward, the first inclined surface will press against the buffer groove 3, thereby reducing the diameter of the body 1 and reducing the friction between the body 1 and the end face of the capsule cup. When the body 1 moves downward, the buffer groove 3 facilitates the deformation of the first inclined surface, further increasing the pre-tightening force between the second end face 2 of the body 1 and the end face of the capsule cup.

[0046] Optionally, in some embodiments, the buffer groove 3 is composed of a first buffer surface 301 and a second buffer surface 302. The first buffer surface 301 is an arc surface with its opening facing away from the body 1. That is, the first buffer surface 301 adopts an arc-shaped groove structure, which further enhances the buffer groove 3's ability to accommodate or support the deformation of the second end face 2 of the body 1.

[0047] Optionally, in some embodiments, the second buffer surface 302 is a plane and forms a preset angle with the first end face 4.

[0048] In the above embodiment, the angle between the second buffer surface 302 and the first end face 4 is less than 90 degrees. At this time, the second buffer surface 302 can further reduce the diameter of the body 1 when the body 1 moves upward, thereby reducing the resistance when moving upward.

[0049] In other embodiments, the angle between the second buffer surface 302 and the first end face 4 is greater than 90 degrees. In this case, when the body 1 moves downward, the second buffer surface 302 can further enhance the support force on the second end face 2 of the body 1 and improve its sealing performance.

[0050] Optionally, in some embodiments, the connection between the first buffer surface 301 and the second buffer surface 302 is rounded.

[0051] A capsule cup comprising the sealing structure described in any of the preceding claims.

[0052] Please refer to Figure 1 In some embodiments, the capsule cup includes a pressure chamber 5 and a water holding chamber 6. The water holding chamber 6 is sleeved outside the pressure chamber 5, and a sealing structure is installed on the pressure chamber 5. The first end face 4 contacts the outer wall of the pressure chamber 5, and the second end face 2 contacts the inner wall of the water holding chamber 6. That is, the body 1 is installed on the pressure chamber 5, and the body 1 is used for sealing between the pressure chamber 5 and the water holding chamber 6.

[0053] Optionally, in some embodiments, the pressure chamber 5 is provided with an installation protrusion 8, and the body 1 is provided with an installation groove 7. When the installation protrusion 8 is placed in the groove, the sealing structure is installed in the pressure chamber 5. That is, the pressure chamber 5 is provided with a protrusion, and the body 1 is provided with a groove that cooperates with the protrusion. Through the elastic deformation function of the body 1, the body 1 is fitted onto the pressure chamber 5 to fix the pressure chamber 5.

[0054] In the above embodiment, the pressure chamber 5 is provided with an annular pressure plate, which is located above the mounting protrusion 8, and the body 1 is in contact with the annular pressure plate. Therefore, when the pressure chamber 5 moves downward, the annular pressure plate can prevent the body 1 from detaching from the pressure chamber 5 or from being displaced, thus further ensuring its sealing effect.

[0055] Optionally, in some embodiments, the top of the water tank 6 is provided with a buckle. After the pressure tank 5 is fully inserted into the water tank 6, the buckle can prevent the pressure tank 5 from moving upward, further ensuring the purpose of sealing the body 1 by squeezing and deforming it.

[0056] In other words, the key point of this utility model is that the body 1 is fixed to one of the workpieces, so the body 1 can move with one of the workpieces to achieve relative sliding between the body 1 and the other workpiece. One end face of the body 1 has a non-zero angle with the sliding end face of the other workpiece. When the body 1 moves with one of the workpieces, since there is an angle between the end face and the sliding contact surface of the workpiece, the body 1 will deform in different directions of movement. When moving towards the side inclined to the end face, the friction between the end face and the sliding contact surface of the workpiece can cause the body 1 to be squeezed and deformed, thereby increasing its sealing performance. When moving towards the side inclined away from the end face, the body 1 will not be squeezed and deformed, thus reducing the force required to move in this direction.

[0057] In addition to the sealing structures disclosed in the above embodiments, this utility model also provides a capsule cup including the above-described sealing structure. For the structure of other parts of the capsule cup, please refer to the prior art, which will not be described in detail here.

[0058] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0059] The sealing structure and capsule cup provided by this utility model have been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
