Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of voltage stabilizing, specifically relates to a voltage stabilizing cover. BACKGROUND

[0002] The chemical components contained in traditional Chinese medicines and traditional Chinese medicine decoction pieces are very complex, contain various effective components, ineffective components and toxic components. For traditional Chinese medicines, extracting effective components and further separating and purifying the effective components to obtain effective monomers is an important detection method in the field of traditional Chinese medicine research. Solvent extraction is the most widely used method, which is a method of extracting active components from medicinal material tissues and pieces according to the solubility of various effective components in Chinese herbal medicines and traditional Chinese medicine decoction pieces.

[0003] When analyzing traditional Chinese medicine decoction pieces by a mass spectrometer, organic solvents such as acetonitrile, methanol and ethanol are usually used to extract and analyze effective components. However, some organic solvents are flammable, explosive and toxic, and must be sealed as much as possible and reduced in volatilization during use. If completely sealed, a negative pressure state may be formed during extraction, so that the organic solvents in the sealing device are not easy to extract, affecting the analysis process. In order to balance the air pressure, an air hole is usually arranged on the cover body for storing the organic solvents, for example, an air hole is arranged on the cover of the storage bottle. When the solvents are extracted, external air can enter the storage bottle through the air hole to balance the air pressure. However, part of the solvents may escape from the air hole during use or storage, which may form a local flammable and explosive environment, and is harmful to the body, especially the respiratory tract, and may induce corresponding chronic diseases or occupational diseases.

[0004] To solve the above problems, the existing patent No. CN214107006U discloses a test tube cover, which comprises a top cover made of elastic silica gel and a cylindrical cover body. A cross line opening is arranged at the center of the top cover. Whether liquid is added to the test tube or liquid is taken out, the air pressure inside and outside the test tube can be balanced through the cross line opening to balance the air pressure inside and outside the test tube. In order to smoothly open the channel of the cross line, the thickness of the entire top cover cannot be too thick. However, the cross line opening of the device is a straight line opening. In the case of not adding liquid or not taking out liquid, air may enter the test tube from the cross line opening, and the sealing effect needs to be improved. UTILITY MODEL CONTENTS

[0045] In the embodiment, the elastic film 4 is a film made of latex material, which has good elasticity and good sealing effect when being made into a sealing member with concave-convex structure.

[0046] In the embodiment, the thickness of the elastic film 4 is 1mm.

[0047] After the cover body 1 is connected with the bottle body 8, when the air pressure inside and outside the bottle body 8 is balanced, the concave-convex structures at the contact positions of the adjacent two elastic blocks 5 are in contact with each other, and the first through hole 201 is blocked by the concave-convex structures. When the liquid inside the bottle body 8 is sucked out through the material guide pipe 6, the bottle body 8 is in a negative pressure state. At this time, the atmospheric pressure is greater than the negative pressure in the bottle, the atmospheric pressure extrudes the elastic film 4, the concave-convex structures at the contact positions of the elastic film 4 are disconnected, the elastic film 4 bends towards the inside of the bottle body 8, and the first through hole 201 is opened, so that air enters the inside of the bottle body 8 through the first through hole 201, the air pressure inside and outside the bottle body 8 is balanced, and the transportation of the liquid is smooth.

[0048] The concave-convex structure changes the straight line opening into a zigzag gap, which not only has better sealing effect on the bottle body 8, but also makes the opening and closing of the elastic film 4 more stable during the process of opening and closing the elastic film 4 by the atmospheric pressure.

[0068] In the embodiment, the third through hole is 10 mm in size.

[0069] In the embodiment, the cover 1 and the bottle body 8 are connected through thread connection, which is prior art and will not be described too much.

[0070] The cover 1 and the bottle body 8 are connected through thread connection, the connection mode is simple, the rubber layer 2 is used to achieve a further sealing effect, the sealing effect is good, the first through hole 201 is made of rubber material, the rubber sleeve 3 is connected with the first through hole 201, and the tightness of the connection between the two is improved.

[0074] The specific use method of the utility model is as follows:

[0075] Refer to Figures 1-4When using this device, first connect the cap 1 and the bottle 8 with threads. Initially, the feed tube 6 is directly connected to the cap 1 and can be used directly. Then, connect the rubber sleeve 3 and the first through hole 201 through the first external thread and the first internal thread. The elastic membrane 4 on the rubber sleeve 3 is parallel to the surface of the cap 1. The bottom plate 501 and top plate 502 of each elastic block 5 on the elastic membrane 4 contact the top plate 502 and bottom plate 501 of the adjacent elastic block 5, so that the elastic membrane 4 forms a planar sealing membrane.

[0076] After the connection is prepared, liquid can be fed into or discharged from the bottle 8 through the feed pipe 6. Taking the discharge of liquid to the outside as an example, when discharging liquid from the bottle 8 to the outside, the inside of the bottle 8 will become under negative pressure due to the seal. At this time, the atmospheric pressure outside is greater than the negative pressure inside the bottle, thus the atmospheric pressure exerts pressure on the elastic membrane 4. Under the pressure of atmospheric pressure, the bottom plate 501 and top plate 502 on the interconnected elastic block 5 are disconnected, causing the elastic membrane 4 to bend inwards into the bottle 8, opening the channel on the elastic membrane 4. Air enters the bottle 8 through this channel to balance the air pressure, allowing the liquid inside the bottle 8 to be smoothly discharged to the outside. Conversely, it allows liquid to be stably input into the bottle 8.

[0077] The bottom plate 501 and top plate 502 transform the straight opening into a zigzag-shaped gap, which not only provides a better seal inside the bottle 8, but also makes the opening and closing of the elastic membrane 4 more stable due to the bottom plate 501 and top plate 502. The elastic blocks 5 will not be misaligned, which significantly improves the stability of the device during use.

[0078] Example 2

[0079] This embodiment is basically the same as Embodiment 1, except that: in this embodiment, as shown in the example... Figure 5 As shown, the cover 1 is a rubber stopper 7. The cover 1 includes a top cover and a bottom cover. The size of the bottom cover matches the size of the bottle mouth. When the bottom cover is inserted into the bottle mouth, the top cover abuts against the bottle mouth. The first through hole 201 and the second through hole 202 penetrate the top cover and the bottom cover.

[0080] In this embodiment, the top cover and the bottom cover are integrally formed.

[0081] The cap 1 can be directly connected to the bottle 8 by plugging it in. Because the rubber stopper 7 is elastic, it can seal the bottle 8 with its own elasticity when connected to the bottle 8, resulting in a good sealing effect and simple and convenient operation.
