Description

Technical Field

[0001] This utility model relates to the field of suction cup technology, specifically a one-way valve suction cup. Background Technology

[0002] Existing suction cups are widely used in people's daily lives. However, because existing suction cups require air to be expelled from the periphery during use, the air inside the suction cup is not completely expelled, which affects the suction force of the suction cup. To address the above problems, a one-way valve suction cup is needed. Utility Model Content

[0003] The purpose of this invention is to provide a one-way valve suction cup to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A one-way valve suction cup includes a suction cup body, a venting lever on the side wall of the suction cup body, a straight vent hole at the center of the suction cup body, a conical groove at the bottom of the suction cup body corresponding to the straight vent hole, a bean-shaped boss at the end face of the suction cup body corresponding to the straight vent hole, an annular groove at the bottom of the suction cup body, a limiting boss at the bottom of the suction cup body, and venting grooves interlaced on the limiting boss.

[0006] As a preferred embodiment of this utility model, the suction cup body and the venting lever are an integral structure, and multiple sets of positioning holes are provided on the end face of the suction cup body.

[0007] As a preferred embodiment of this utility model, the length of the single-line exhaust hole is generally the same as that between the conical groove and the bean-shaped boss.

[0008] As a preferred embodiment of this utility model, the diameter of the conical groove is consistent with the diameter of the bean-shaped boss.

[0009] As a preferred embodiment of this utility model, an air nozzle connection hole is provided on the end face of the suction cup body and on the outside of the bean-shaped protrusion.

[0010] As a preferred embodiment of this utility model, the ventilation groove is provided with two longitudinal and two transverse sections, with the two ventilation grooves being located on the limiting protrusion.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, a suction cup body, a venting lever, a straight vent hole, a conical groove, a bean-shaped boss, an annular groove, a limiting boss, and a venting groove are provided in the one-way valve suction cup. The interaction between these components allows for efficient air intake. When air is drawn in, the straight vent hole opens to release air. After the air is released, the vacuum space is under negative pressure, causing the straight vent hole to close, achieving a sealed state. The opening and closing of the straight vent hole, due to the structural action of the conical groove and the bean-shaped boss, creates a lever arm. This lever arm is short when air is drawn in and long when sealing, thus facilitating air release while improving the airtightness after sealing. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, and several embodiments of the utility model will be provided. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and complete.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] For an example, please refer to... Figure 1-3 This utility model provides a technical solution:

[0023] A one-way valve suction cup includes a suction cup body 1, a venting lever 2 on the side wall of the suction cup body 1, a straight vent hole 3 at the center of the suction cup body 1, a conical groove 4 at the bottom of the suction cup body 1 corresponding to the straight vent hole 3, a bean-shaped boss 5 at the end face of the suction cup body 1 corresponding to the straight vent hole 3, an annular groove 6 at the bottom of the suction cup body 1, a limiting boss 7 at the bottom of the suction cup body 1, and ventilation grooves 8 interlaced on the limiting boss 7;

[0024] In this embodiment, reference Figure 1 , Figure 2 , Figure 3 and Figure 4 When air is drawn in, the straight exhaust port 3 opens to exhaust air. After exhausting the air, the vacuum space is under negative pressure. At this time, the straight exhaust port 3 closes under the negative pressure to achieve a sealed state. Of course, when the straight exhaust port 3 opens and closes, the structure of the conical groove 4 and the bean-shaped protrusion 5 will generate a lever arm. When air is drawn in, the lever arm is short, and when air is sealed, the lever arm is long, thus improving the airtightness after sealing.

[0025] Furthermore, the suction cup body 1 and the venting lever 2 are integrated into one structure, making the device more convenient to manufacture.

[0026] Furthermore, multiple sets of positioning holes are provided on the end face of the suction cup body 1 to facilitate connection with the connector;

[0027] Furthermore, the length of the straight vent 3 is roughly the same as that of the conical groove 4 and the bean-shaped protrusion 5, which makes it convenient for the straight vent 3 to be opened when the device is in use.

[0028] Furthermore, the diameter of the conical groove 4 is consistent with the diameter of the bean-shaped protrusion 5. When air is drawn in, the opening and closing of the straight exhaust hole 3 causes the conical groove 4 and the bean-shaped protrusion 5 to generate a lever arm. When air is drawn in, this lever arm is short, while when air is sealed, the lever arm is long, thus improving the airtightness after sealing.

[0029] Furthermore, an air nozzle connection hole is provided on the end face of the suction cup body 1 and on the outside of the bean-shaped protrusion 5, which can be quickly connected to the air nozzle of the negative pressure device.

[0030] Furthermore, the ventilation groove 8 is provided with two longitudinal and two transverse sections, with the two ventilation grooves 8 being located on the limiting boss 7, so that air can be discharged through the straight exhaust hole 3.

[0031] The working process of this utility model is as follows: When using the one-way valve suction cup, when air is sucked in, the straight exhaust hole 3 will open to achieve the function of venting. After the air is vented, the vacuum space is in a negative pressure state. At this time, the straight exhaust hole 3 will close under the action of negative pressure to achieve a sealed state. Of course, when the straight exhaust hole 3 opens and closes, the action of the conical groove 4 and the bean-shaped protrusion 5 will generate a lever arm. When air is sucked in, this lever arm is short, and when air is sealed, this lever arm is long, thus improving the airtightness after sealing.

[0032] The hemispherical part on top will better prevent airflow backflow when the vacuum pump is compressing gas.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
