As shown in fig. 1, in the present embodiment, the pressure relief cover opening device provided by the present invention includes a cavity, a sealing sleeve 130, and a contact 140. Referring to fig. 2, fig. 2 representatively illustrates a schematic view of a state of use of a pressure relief cover opening device capable of embodying the principles of the present invention, and in particular illustrates a schematic state of a sealing sleeve 130 and contacts 140 of the pressure relief cover opening device during a pressure relief cover opening process. The structure, connection mode and functional relationship of the main components of the pressure relief cover opening device provided by the utility model will be described in detail below with reference to the attached drawings.

As shown in fig. 1 and 2, in the present embodiment, the inner cavity of the chamber is provided with an adsorbent 111, and the top wall and the bottom wall of the chamber are respectively provided with a hole communicating the inner cavity with the outside. The sealing sleeve 130 has one end connected to the bottom wall of the chamber, and the other end contacting the container 200 and surrounding the pressing elastic cap 210. In the pressure-releasing cap-opening process, the pressure-releasing cap-opening device can contact the container 200 through the other end of the sealing sleeve 130, so that the sealing sleeve 130 can form a seal between the cavity and the pressing elastic cap 210. The contact 140 is disposed on the bottom wall of the cavity and located in the sealing sleeve 130, and the contact 140 can trigger to press the elastic cap 210 in the process of opening the cap by pressure relief. Through the structural design, the elastic cover 210 can be triggered and pressed, meanwhile, the sealing sleeve 130 is used for ensuring the sealing of the part for pressing the elastic cover 210, so that air can only flow through the adsorbent 111 through the gap of the cavity in the pressure relief process, and the adsorbent 111 is used for adsorbing moisture in the air, so that the moisture in the air is prevented from entering the container 200 in the cover opening process, and the pollution of products in the container 200 is avoided.

Optionally, as shown in fig. 1, in the present embodiment, the cavity may include a body 110 and a cover 120. Specifically, the body 110 has a substantially barrel-shaped structure, and a barrel bottom portion of the barrel-shaped structure can define a bottom wall of the cavity. The cover 120 is detachably disposed on the bung portion of the body 110, the cover 120 can define a top wall of the cavity, and the cover 120 and the body 110 can form an inner cavity of the cavity when the cover is closed on the body 110. On the basis, the bottom wall of the cavity (i.e. the bottom portion of the body 110) is provided with a hole 112, and the top wall of the cavity (i.e. the cover 120) is provided with a hole 121, and the hole 112 and the hole 121 can communicate the inner cavity of the cavity with the outside, so that air can flow through the cavity via the inner cavity provided with the adsorbent 111. With the above-described configuration, the present invention can replace the adsorbent 111 (and the filter membrane 150 described below) in the chamber by attaching and detaching the lid 120.

Further, the body 110 and the cover 120 may be screwed in the present embodiment based on the structural design that the cover 120 is detachably provided on the body 110. For example, the cover 120 may be provided with an internal thread, and the body 110 may be provided with an external thread, and the cover 120 and the body 110 may be detachably connected by screw-fitting the internal thread and the external thread. In other embodiments, the body 110 and the cover 120 may be detachably connected by other methods, such as clamping, bonding, etc., and the present embodiment is not limited thereto.

Further, based on the structural design of the cavity containing the body 110, in the present embodiment, the body 110 may be made of a transparent material.

Further, as shown in fig. 1, based on the structural design that the cavity includes the cover 120, in the present embodiment, a handle may be disposed outside the cover 120. Through the structural design, the utility model can be used for pressing the cavity by applying force by operating the handle by a user, so that the contact 140 is pressed downwards to trigger the pressing of the elastic cover 210.

Alternatively, as shown in fig. 1, in the present embodiment, the sealing sleeve 130 may be a sealing rubber ring. Wherein, the sealing rubber ring is approximately in a corrugated pipe structure. Through the structural design, the elastic deformation and elastic recovery of the sealing sleeve 130 can be realized by using rubber materials, and the sealing sleeve 130 can be guided by using a corrugated pipe-shaped structure to keep right opposite to the pressing elastic cover 210 in the elastic deformation process, so that the accurate triggering of the contact 140 is ensured. In other embodiments, the sealing sleeve 130 may be made of other elastic materials, and is not limited to this embodiment.

Further, based on the design that the material of the sealing sleeve 130 includes an elastic material, in the present embodiment, the length of the sealing sleeve 130 in the fully released state is greater than the length of the contact 140. Through the structural design, when the other end of the sealing sleeve 130 contacts the surface of the container 200, the sealing sleeve 130 is not pressed and keeps longer than the contact 140, so that the contact 140 cannot trigger the pressing of the elastic cover 210 when a user does not press the contact, and the controllability of the pressure relief cover opening device is further optimized.

Further, when the pressing elastic cap 210 protrudes from the surface of the container 200, that is, the pressing elastic cap 210 has a protruding thickness protruding from the surface of the container 200, the length of the sealing sleeve 130 in the fully released state may be further greater than the sum of the length of the contact 140 and the protruding thickness. Through the structural design, the utility model can ensure that the contact 140 cannot trigger the pressing elastic cover 210 when a user does not apply pressure in the application scene that the pressing elastic cover 210 protrudes out of the surface of the container 200, thereby further optimizing the controllability of the pressure relief cover opening device.

Alternatively, in the present embodiment, the adsorbent 111 may be a regenerable and reusable adsorbent material.

Optionally, as shown in fig. 1, in this embodiment, the pressure-relief cover-opening device provided by the present invention may further include a filter membrane 150. The filter membrane 150 is disposed within the cavity. Through the structural design, the air filter can filter particles in the air by using the filter membrane 150, and the particles in the air are prevented from entering the container 200 to pollute products.

Based on the above detailed description of an exemplary embodiment of the pressure-relief cover-opening device according to the present invention, a method of using the pressure-relief cover-opening device will be described below.

As shown in fig. 1 and 2, when it is necessary to release the cap of the container 200, the rubber packing sleeve 130 is brought into contact with the container 200 and surrounds the pressed elastic cap 210. Pressing the handle (or directly pressing down the cavity) brings the contact 140 into contact with the pressing elastic cap 210, and applying a force by pressing the handle (or directly pressing down the cavity) triggers the pressing of the elastic cap 210. Under the effect of the negative pressure environment in the container 200, the outside air enters the inner cavity of the cavity through the pores on the top wall of the cavity, and enters the sealing sleeve 130 through the pores on the bottom wall of the cavity after being adsorbed and filtered by the adsorbent 111 and the filtering membrane 150, and the dried and purified air finally enters the container 200 through the pressing elastic cover 210 after being triggered and opened, so that the pressure relief of the container 200 and the opening of the pressing elastic cover 210 are completed. Therefore, the pressure relief cover opening device provided by the utility model can remove moisture and particulate matters in the air on the premise of ensuring that products such as lubricating oil are not polluted, and can realize adsorption, filtration and pressure relief at the same time. When the pressure inside and outside the container 200 reaches the equilibrium, the device is stopped to be used, and the environment polluting the product does not exist, thereby ensuring the sampling accuracy and the safety of the product use.

It should be noted herein that the pressure relief cover release devices shown in the drawings and described in this specification are only a few examples of the many types of pressure relief cover release devices that can employ the principles of the present invention. It should be clearly understood that the principles of the present invention are in no way limited to any details or any components of the pressure relief door opener arrangement shown in the drawings or described in the present specification.

In summary, the pressure relief cover opening device provided by the utility model comprises a cavity, a sealing sleeve and a contact. The inner cavity of the cavity is provided with an adsorbent, and the top wall and the bottom wall of the cavity are respectively provided with a hole for communicating the inner cavity with the outside. One end of the sealing sleeve is connected with the bottom wall of the cavity, and the other end of the sealing sleeve is used for contacting the container and surrounding the pressing elastic cover so as to form sealing between the cavity and the pressing elastic cover; the contact is arranged on the bottom wall of the cavity and positioned in the sealing sleeve to trigger and press the elastic cover. Through the structural design, the elastic cover can be triggered and pressed, meanwhile, the sealing of the part of the elastic cover is guaranteed by the sealing sleeve, so that air can only flow through the adsorbent through the gap of the cavity in the pressure relief process, and the adsorbent is used for adsorbing moisture in the air, so that the moisture in the air is prevented from entering the container in the cover opening process, and the pollution of products in the container is avoided.
