Description

Technical Field

[0001] The utility model belongs to the field of gas leak detection equipment, in particular to a vacuum chamber and a gas leak detection equipment. Background Art

[0002] Gas leak detection equipment is an analytical instrument that uses the mass-to-charge ratio of ionized molecules or atoms to determine the composition and structure of a sample. Its operating principle is based on the deflection of charged particles in an electromagnetic field. By separating and detecting atoms, molecules, or molecular fragments based on their mass differences, it analyzes the composition of a substance. With the rapid development of the domestic electrical industry, gas leak detection equipment has been widely used in lithium battery leak detection scenarios.

[0003] In the prior art, lithium battery leakage detection devices typically include a vacuum chamber, which houses the lithium battery under test. Specifically, when testing a lithium battery, the vacuum chamber is opened and the battery is placed inside. After testing is complete, the vacuum chamber is opened again and the battery is removed from the chamber.

[0004] However, the applicant has discovered in practice that, during prolonged use, the sides of some lithium batteries are made of plastic and are relatively smooth. Consequently, when placing or removing the lithium batteries from the vacuum chamber, they can easily slip and fall to the bottom of the chamber. This can lead to damage and deformation of the bottom of the chamber after repeated drops over extended periods of time. Utility Model Content

[0005] The utility model provides a vacuum chamber and a gas leak detection device, which aims to solve the problem that the bottom of the vacuum chamber is damaged due to collision between a lithium battery and the vacuum chamber.

[0006] In order to achieve the above-mentioned object, the utility model provides a vacuum chamber, comprising a chamber body and a buffer mechanism, wherein the buffer mechanism is arranged at the inner bottom of the chamber body;

[0007] The buffer mechanism includes a spring, a guide sleeve and a buffer groove. The buffer groove is located at the inner bottom of the cabin body. The guide sleeve includes an outer cylinder and an inner cylinder. The outer cylinder is sleeved on the inner cylinder. The outer cylinder and the inner cylinder are respectively installed on the bottom of the buffer groove and the inner bottom of the cabin body. The spring is sleeved on the guide sleeve. Both ends of the spring are in contact with the bottom of the buffer groove and the inner bottom of the cabin body respectively.

[0008] In this solution, the lithium battery is contained within a chamber, and a buffer mechanism is provided at the bottom of the chamber. If the lithium battery accidentally falls, the buffer mechanism reduces the impact of the lithium battery on the bottom of the chamber, thus preventing the chamber from being damaged by the lithium battery.

[0009] Preferably, in order to ensure the stability of the buffer groove, the buffer mechanism of this solution includes at least two guide sleeves, each of which is arranged at a different position on the bottom of the cabin; and each of the guide sleeves is equipped with a spring.

[0010] The buffer groove of this solution is supported by a plurality of guide sleeves, so the buffer groove is more stable when subjected to impact.

[0011] Preferably, in order to ensure that multiple positions of the buffer groove are supported, the guide sleeves of this solution are distributed in a ring shape on the inner bottom of the cabin.

[0012] Alternatively, in order to ensure that multiple positions of the buffer groove are supported, the guide sleeves described in this solution are distributed in a cross shape on the inner bottom of the cabin.

[0013] Preferably, in order to facilitate the disassembly of the buffer tank, the inner cylinder and the outer cylinder described in this solution can be detachably connected.

[0014] When the inner and outer cylinders are set to a detachable state, when the buffer tank needs to be replaced or the interior of the cabin needs to be cleaned, it is only necessary to separate the inner and outer cylinders to prevent the inner and outer cylinders from obstructing the disassembly of the buffer tank.

[0015] Preferably, in order to achieve a detachable connection between the inner cylinder and the outer cylinder, the surface of the inner cylinder of this solution is provided with an elastic buckle, and the side wall of the outer cylinder is constructed with a limiting groove; the elastic buckle is embedded in the limiting groove, and the inner cylinder is connected to the outer cylinder; the elastic buckle is disengaged from the limiting groove, and the inner cylinder is separated from the outer cylinder.

[0016] In this solution, when the elastic buckle is embedded in the limiting groove, the inner tube and the outer tube are connected to each other; when the elastic buckle is separated from the limiting groove, the inner tube and the outer tube can be separated.

[0017] Preferably, in order to ensure a more stable connection between the inner tube and the outer tube, the elastic buckles of this solution are provided on both sides of the inner tube, and the limiting grooves are provided on both sides of the outer tube.

[0018] Preferably, in order to facilitate the disengagement of the elastic buckle from the limiting groove, the elastic buckle described in this solution includes an arc-shaped protrusion.

[0019] The second aspect of the present invention discloses a gas leak detection device, comprising the above-mentioned vacuum chamber. By using the above-mentioned vacuum chamber, the problem of the vacuum chamber being damaged by the lithium battery is solved.

[0020] The beneficial effect of the present invention is that the lithium battery is contained within the compartment, and a buffer mechanism is disposed on the inner bottom of the compartment. When the lithium battery accidentally falls, the buffer mechanism reduces the impact of the lithium battery on the bottom of the compartment, thereby preventing the bottom of the compartment from being damaged by the lithium battery.

[0027] To make the objectives, technical solutions, and advantages of the embodiments more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. When the following description refers to the drawings, unless otherwise indicated, identical numbers in different drawings represent identical or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0028] In this disclosure, unless otherwise specified, directional terms such as "inner" and "outer" are defined based on the contours of the corresponding components. Terms such as "first" and "second" are used in this disclosure to distinguish one element from another and do not convey order or importance.

[0029] Example 1

[0030] Basically as attached Figure 1 To the attached Figure 2 As shown, a vacuum chamber is used to store lithium batteries. The vacuum chamber specifically includes a chamber body 1 and a buffer mechanism 3 disposed at the bottom of the chamber body 1. The buffer mechanism 3 protects the bottom of the chamber body 1, preventing damage to the bottom of the vacuum chamber from lithium batteries and extending the service life of the vacuum chamber.

[0031] The chamber body 1 in the embodiment of the present disclosure may be a rectangular chamber body 1, a circular chamber body 1 or an elliptical chamber body 1 or other vacuum chamber bodies 1 in the prior art. Figure 1 and Figure 2As shown, the chamber 1 is equipped with a door 11, which is used to close and open the chamber 1. When the door 11 is open, lithium batteries can be loaded and unloaded from the chamber 1. When the lithium batteries are being tested, the door 11 closes the chamber 1, sealing it. Furthermore, pipes 2 are provided on both sides of the chamber 1, enabling communication with external devices.

[0032] like Figure 3 As shown, in this embodiment, a buffer mechanism 3 is configured at the bottom of the cabin body 1. The buffer mechanism 3 specifically includes a spring 31, a guide sleeve 32 and a buffer groove 33. The buffer mechanism 3 protects the bottom of the cabin body 1.

[0033] In this embodiment, the buffer groove 33 is preferably a metal groove, and the shape of the buffer groove 33 is adapted to the inner bottom of the cabin body 1. That is, when the bottom of the cabin body 1 is circular, the buffer groove 33 is a circular groove; when the bottom of the cabin body 1 is rectangular, the buffer groove 33 is a rectangular groove.

[0034] like Figure 4 and Figure 5 As shown, in this embodiment, the guide sleeve 32 is disposed below the buffer groove 33. The guide sleeve 32 comprises an inner sleeve 321 and an outer sleeve, with the inner sleeve 321 disposed within the outer sleeve. When the inner sleeve 321 is inserted into the outer sleeve, the inner sleeve 321 can slide upward and downward within the outer sleeve. The spring 31 is specifically a compression spring 31, which is sleeved onto the guide sleeve 32. To facilitate removal of the spring 31, both ends of the spring 31 are fixedly connected to the bottom of the cabin 1 and the bottom of the buffer groove 33, maintaining contact therewith.

[0035] For example, if a lithium battery is accidentally dropped, the buffer mechanism 3 on the inner bottom of the housing 1 will cause it to land on the buffer groove 33. The impact force of the lithium battery will pass through the buffer groove 33 and act on the spring 31. The spring 31 is compressed, mitigating the impact force, preventing damage to the inner bottom of the housing 1 and extending the service life of the housing 1.

[0036] like Figure 3 As shown, in this embodiment, a plurality of guide sleeves 32 are disposed at the bottom of the buffer groove 33. The guide sleeves 32 can be arranged in an annular shape, for example, a circular ring shape. Alternatively, the guide sleeves 32 can be arranged in a cross shape. By configuring the plurality of guide sleeves 32 to support the buffer groove 33, the buffer groove 33 is supported at all positions, making the buffer groove 33 more stable. Furthermore, in this embodiment, a spring 31 is preferably mounted on each guide sleeve 32.

[0037] Because the chamber 1 involves the removal and placement of lithium batteries, external impurities can easily enter the interior of the chamber 1. When impurities are present within the chamber 1, the interior of the chamber 1 needs to be cleaned regularly to prevent them from affecting lithium battery testing. During cleaning and maintenance of the interior of the chamber 1, the buffer groove 33 will obviously block impurities, affecting the cleaning and maintenance of the interior of the vacuum chamber. Therefore, in this embodiment, the guide sleeve 32 is configured to be detachably connected. In specific implementation, the inner cylinder 321 is embedded within the outer cylinder, and a limit buckle is provided on the outer surface of the inner cylinder 321. The limit buckle includes a spring and a protrusion. The spring is in the shape of a rectangular sheet and can deform and automatically rebound under the action of external force. The surface of the spring is provided with a protrusion, which is a circular arc-shaped protrusion. At the same time, the surface of the outer cylinder is provided with a limit groove 322a, which is an elongated rectangular groove. When the inner tube 321 is inserted into the outer tube, the protrusion fits into the retaining groove 322a. To separate the inner tube 321 from the outer tube, simply pull the inner tube 321 outward, causing the spring to deform and the protrusion to separate from the retaining groove 322a. Once the protrusion is separated from the retaining groove 322a, it no longer serves as a retaining mechanism, and the inner tube 321 and outer tube can be separated.

[0038] In this embodiment, two elastic buckles 321a are provided, one on each side of the inner tube 321. Furthermore, retaining grooves 322a are also provided on either side of the outer tube. The symmetrically positioned elastic buckles 321a and retaining grooves 322a cooperate with each other. The secure connection achieved by the elastic buckles 321a and retaining grooves 322a provides greater stability for the inner tube 321 and outer tube.

[0039] Because impurities can enter the inner and outer cylinders, in this embodiment, the inner cylinder 321 is removably mounted to the bottom of the buffer tank 33 to facilitate cleaning. To achieve this, a threaded hole is provided at the bottom of the buffer tank 33, and external threads are provided at the end of the inner cylinder 321. The inner cylinder 321 is removably mounted to the inner bottom of the buffer tank 33 via the threaded hole. The outer cylinder can also be removably mounted to the inner bottom of the chamber 1. To achieve this, a vertical screw 34 is provided at the inner bottom of the chamber 1, and internal threads are provided on the inner wall of the bottom end of the outer cylinder. The screw 34 is installed in the threaded hole, allowing the outer cylinder to be removably mounted to the bottom of the chamber 1. Since both the inner and outer cylinders are removably mounted, when cleaning is required, the inner cylinder 321 can be removed from the bottom of the buffer tank 33 and the outer cylinder can be removed from the bottom of the chamber 1 to complete the cleaning process.

[0041] This embodiment provides a gas leak detection device, including the vacuum chamber described in Example 1 and a gas leak detection device body. The relevant structure of the gas leak detection device body can refer to the existing technology.

[0042] In this embodiment, the vacuum chamber is used as the chamber body 1 for placing lithium batteries in the gas leak detection equipment. The buffer mechanism 3 at the bottom of the vacuum chamber can protect the bottom of the vacuum chamber, thereby effectively avoiding the problem of the vacuum chamber being damaged by the falling lithium batteries in the prior art.

[0043] The above is only an embodiment of the present invention, and the commonly known specific structures and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, and these should also be regarded as the scope of protection of the present invention.
