Description

Technical Field

[0001] This invention relates to the field of sealing mechanism technology, and in particular to a multifunctional sealing bottle. Background Technology

[0002] A sealed bottle is a container used to store materials and prevent them from evaporating. Existing sealed bottles generally consist of a bottle body and a cap, which are connected to the bottle body by threads. A sealing gasket is placed at the bottle opening to prevent the contents from evaporating.

[0003] Currently, there are two methods for detecting volatile gases: low-concentration detection and high-concentration detection. When using high-concentration detection, the bottle cap can be unscrewed and removed. However, when using low-concentration detection, existing sealed bottles cannot be used. Summary of the Invention

[0004] To overcome the technical shortcomings of existing sealed bottles that are not suitable for low-concentration detection, this invention provides a multifunctional sealed bottle.

[0005] The multifunctional sealing bottle provided by this invention includes:

[0008] The mounting cover includes a stud portion and a cover body portion. The stud portion is screwed into the interior of the main housing and located on the front side of the mounting barrel. The cover body portion is located on the front side of the stud portion. The cover body portion fits against the front end face of the main housing and a first sealing ring is provided at the contact point.

[0009] A sealing element is slidably sleeved inside the rear end of the main housing and located in front of the annular baffle. The rear end face of the sealing element is provided with a second sealing ring. The sealing element has a sealing state in which the second sealing ring abuts against the annular baffle and a ventilated state in which the second sealing ring disengages from the annular baffle.

[0010] A drive component connected to the plugging element and adapted to drive the plugging element to switch between a plugging state and a venting state.

[0011] Optionally, the inner hole of the main housing is a stepped hole with the small diameter hole located behind the large diameter hole. The sealing member is placed in the small diameter hole, and a support cylinder is sleeved in the large diameter hole. The rear end of the support cylinder abuts against the stepped surface of the stepped hole, and the front end abuts against the mounting bucket.

[0012] Optionally, the drive assembly includes a top cap and a spring;

[0013] The rear end of the sealing component is provided with a first connecting shaft, which passes through the annular baffle and is fixedly connected to the top cap.

[0014] The spring is placed inside the support barrel, and the spring is pressed between the sealing member and the mounting barrel.

[0015] Optionally, the drive assembly further includes a linkage component and a locking component;

[0016] The inner wall of the support cylinder is provided with a convex ring at the rear end and several convex strips evenly distributed along the circumference of the convex ring. The convex strips extend forward along the axial direction and the front end is set as an inclined surface. Adjacent convex strips form guide grooves. The guide grooves are divided into two groups with different groove depths and the two groups of guide grooves are alternately distributed. Several guide strips are evenly distributed along the circumference on the outer wall of the linkage. The guide strips are provided with two groups with different thicknesses corresponding to the guide grooves. The guide strips are slidably connected in the corresponding guide grooves. The rear end of the linkage is provided with a second connecting shaft. The second connecting shaft passes through the rear end of the support cylinder and is fixedly connected to the sealing member.

[0017] The locking component includes a guide post and a locking strip. The guide post is inserted into the center of the front end of the linkage component with a gap. The locking strip is located at the front end of the guide post. The locking strip has multiple guide grooves with a corresponding depth. The rear end of the locking strip is set as an inclined surface.

[0018] The spring is pressed between the locking member and the mounting barrel.

[0019] Optionally, the locking member has a baffle at its front end, and the rear end of the spring abuts against the baffle.

[0020] Optionally, the baffle is provided with vent holes, which are staggered from the card strip.

[0021] Optionally, the first connecting shaft is threadedly connected and fixed to the top cap, and the second connecting shaft is threadedly connected and fixed to the sealing component.

[0025] Optionally, the outer wall of the main housing is roughened.

[0026] Optionally, the main housing is made of aluminum alloy.

[0027] The technical solution provided by this invention has the following advantages compared with the prior art:

[0028] The multifunctional sealed bottle provided by this invention includes an installation bucket and an installation cap. The installation bucket has a cavity suitable for containing materials. The installation cap is sealed to the main shell by a first sealing ring. Opening the installation cap exposes the material to the air, enabling rapid high-concentration release to meet the requirements of high-concentration detection. It also includes a sealing element and a driving assembly. The driving assembly switches the sealing element between a sealing state and a venting state. When the sealing element is in the sealing state, the rear end of the main shell is sealed to ensure sealing performance. When the sealing element is in the venting state, a gap is formed between the sealing element and the main shell. The sublimated gas from the material can diffuse out through the vent holes at the bottom of the installation bucket. Because the material is stored at the front end and the gas diffuses out through the vent holes and the gap, a low concentration of volatile gas is formed at the rear end of the main shell to meet the requirements of low-concentration detection. This multifunctional sealed bottle of the present invention can output both high-concentration and low-concentration gases while ensuring the sealed storage of materials. It integrates multiple functions, is highly practical, and easy to operate. Attached Figure Description

[0042] To better understand the above-mentioned objectives, features, and advantages of the present invention, the solutions of the present invention will be further described below. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.

[0043] In this description, it should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. It should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joint" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0044] Many specific details are set forth in the following description in order to provide a full understanding of the invention, but the invention may also be practiced in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the invention, and not all embodiments.

[0045] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0046] Reference Figure 1 and Figure 2 This embodiment provides a multifunctional sealing bottle, including a main shell 1, a mounting bucket 2, a mounting cap 3, a sealing component 4, and a driving assembly 5.

[0047] Main shell 1:

[0048] Reference Figure 3 The main housing 1 has an open front end and an annular baffle 11 at the rear end.

[0049] like Figure 1 As shown, the main housing 1 has a cylindrical shape. In other embodiments, the main housing 1 can also be prismatic, as long as the inner side is a cylindrical cavity.

[0050] like Figure 1 As shown, the annular baffle 11 is integrally formed with the main housing 1. In other embodiments, the annular baffle 11 can also be fixed to the rear end of the main housing 1 by welding or gluing.

[0051] like Figure 1 As shown, the outer wall of the main housing 1 is roughened. The roughened surface increases the friction between the main housing 1 and the user's hand, making it easier to pick up and preventing it from falling.

[0052] In this embodiment, the main housing 1 is made of aluminum alloy, which is easy to process and provides good sealing after assembly. In other embodiments, the main housing 1 may also be made of stainless steel or other commonly used materials.

[0053] Install bucket 2:

[0054] Reference Figure 4 The installation bucket 2 is fixedly sleeved inside the front end of the main housing 1 with its opening facing forward. The installation bucket 2 is provided with a cavity 223 suitable for containing materials, and the bottom of the installation bucket 2 is provided with a vent hole 224 that allows gas to diffuse through.

[0055] As is easy to understand, a "bucket" is a container structure that is open at one end and closed at the other.

[0056] It should be noted that the aperture of the vent 224 should be selected appropriately. If it is too large, the material residue may fall through the vent 224 and into the back of the fixed bucket. If it is too small, the ventilation volume may be too small. Those skilled in the art can determine the appropriate aperture based on the material and the required concentration of volatile gases.

[0057] like Figure 3As shown, the inner hole of the main housing 1 is a stepped hole, with the small-diameter hole located behind the large-diameter hole. The sealing component 4 is placed inside the small-diameter hole, and a support cylinder 6 is sleeved inside the large-diameter hole. The rear end of the support cylinder 6 abuts against the stepped surface 12 of the stepped hole, and the front end abuts against the mounting bucket 2. In use, the front side of the mounting bucket 2 is limited by the stud portion 31 of the mounting cover 3, and the rear side of the mounting bucket 2 is limited by the support cylinder abutting against the stepped surface 12, thus fixing the mounting bucket 2 relative to the main housing 1. This structure eliminates the need for the mounting bucket 2 to be fitted into the inner side of the main housing 1 with a large interference fit, making installation more convenient and facilitating the disassembly of the mounting bucket 2.

[0058] Specifically, such as Figure 4 As shown, the installation bucket 2 includes a bucket shell 21 and a bucket body 22. The bucket shell 21 is open at both ends and fits into the large-diameter hole, abutting against the support cylinder 6 and the spring 52. The bucket body 22 includes a main body 221 and a retaining ring 222 located at the front end of the main body 221. A cavity 223 is provided inside the bucket body 22. The main body 221 fits into the bucket shell 21, and the retaining ring 222 abuts against the front end face of the bucket shell 21. A vent 224 is located at the bottom of the main body 221. The installation bucket 2 in this embodiment adopts a split structure, which has two advantages: First, when disassembling the installation bucket 2 for cleaning, it is not necessary to remove the entire installation bucket 2, only the bucket body 22 needs to be removed. The frictional resistance during the removal process decreases as the contact area decreases, making the operation more convenient. Second, after the bucket body 22 is removed, the main body 221 is still fitted into the main shell 1, so the misalignment or even falling off of the parts abutting against the rear side of the installation bucket 2 can be avoided.

[0059] Mounting cover 3:

[0060] Reference Figure 5 The mounting cover 3 includes a stud portion 31 and a cover portion 32. The stud portion 31 is screwed into the interior of the main housing 1 and is located on the front side of the mounting barrel 2. The cover portion 32 is located on the front side of the stud portion 31. The cover portion 32 is in contact with the front end face of the main housing 1 and a first sealing ring 33 is provided at the contact point.

[0061] like Figure 5 As shown, an annular groove is formed on the end face of the cover portion 32, and the first sealing ring 33 is embedded in the annular groove to prevent the first sealing ring 33 from shifting or falling off.

[0062] Sealing component 4:

[0063] Reference Figure 6 The sealing component 4 is slidably sleeved inside the rear end of the main housing 1 and located in front of the annular baffle 11. The rear end face of the sealing component 4 is provided with a second sealing ring 41. The sealing component 4 has a sealing state in which the second sealing ring 41 abuts against the annular baffle 11 and a ventilated state in which the second sealing ring 41 is disengaged from the annular baffle 11.

[0064] It should be noted that the gas emitted from the vent 224 can diffuse through the gap between the sealing member 4 and the main housing 1. In this embodiment, to ensure the gas passage rate, multiple notches 43 are evenly distributed circumferentially on the sealing member 4, located outside the second sealing ring 41, to facilitate gas passage. In other embodiments, multiple axial holes located outside the second sealing ring 41 can also be formed on the sealing member 4 to achieve the same purpose of facilitating gas passage.

[0065] Driver Component 5:

[0066] The drive assembly 5 is connected to the plugging component 4 and is adapted to drive the plugging component 4 to switch between a plugging state and a ventilated state.

[0067] like Figure 2 As shown, the drive assembly 5 includes a top cap 51 and a spring 52; the rear end of the sealing member 4 is provided with a first connecting shaft 42, which passes through the annular baffle 11 and is fixedly connected to the top cap 51; the spring 52 is placed inside the support barrel and pressed between the sealing member 4 and the mounting barrel 2. External force presses the sealing member 4 through the top cap 51 to switch it to the ventilated state to release low-concentration gas; when the external force is released, the top cap 51 resets under the action of the spring 52, causing the sealing member 4 to switch to the sealing state to complete the sealing of the entire sealed bottle. This drive assembly 5 has a relatively simple structure and is easy to operate. In other embodiments, the drive assembly 5 can also use an electric push rod or other linear power element, as long as it can drive the sealing member 4 to move axially to complete its switching between two states.

[0068] Furthermore, such as Figure 2 , Figures 7 to 9As shown, the drive assembly 5 also includes a linkage 53 and a locking element 54; the inner wall of the support cylinder 6 is provided with a rear-end convex ring 63 and several convex strips 61 evenly distributed around the convex ring 63. The convex strips 61 extend forward axially and have a beveled front end. Adjacent convex strips 61 form guide grooves 62. The guide grooves 62 are divided into two groups with different groove depths, and the two groups of guide grooves 62 are alternately distributed. Several guide strips 531 are evenly distributed around the outer wall of the linkage 53. The guide strips 531 are provided with two groups with different thicknesses corresponding to the guide grooves 62. The guide strips 531 are slidably connected. Within the corresponding guide groove 62, the rear end of the linkage 53 is provided with a second connecting shaft 532. The second connecting shaft 532 passes through the rear end of the support cylinder 6 and is fixedly connected to the sealing member 4. The locking member 54 includes a guide post 541 and a locking strip 542. The guide post 541 is inserted into the center of the front end of the linkage 53. The locking strip 542 is located at the front end of the guide post 541. The locking strip 542 is provided with multiple strips corresponding to a deeper set of guide grooves 62. The rear end of the locking strip 542 is set as an inclined surface. The spring 52 is pressed between the locking member 54 and the mounting cylinder 2. The linkage 53 and locking element 54 form the pressing structure of a ballpoint pen: When the top cap 51 drives the sealing element 4 and the linkage 53 to move forward, the guide bar 531 and the locking bar 542 both move forward along the deeper guide groove 62. When the locking bar 542 slides out of the guide groove 62, because the rear end of the locking bar 542 is set as an inclined surface and the front end is supported by the spring 52, the guide bar 531 continues to move forward and will drive the locking bar 542 to rotate to the adjacent shallower guide groove 62 through the inclined surface. However, because the locking bar 542 is set to correspond to the deeper guide groove 62, its thickness is greater than the groove depth of the shallower guide groove 62, so the locking bar 542 will be stuck in the shallower guide groove. At the opening of groove 62, the retaining strip 542 disengages from the guide strip 531, causing the guide strip 531 to lose its forward pressure. Consequently, the sealing element 4 also loses its forward pressure, ultimately causing the second sealing ring 41 to disengage from the annular baffle 11, creating a gap and switching to a ventilated state, through which gas is released. When the guide strip 531 moves forward and contacts the retaining strip 542 again, causing it to rotate again, the retaining strip 542 re-enters the deeper guide groove 62 and, under the action of the spring 52, pushes the guide strip 531 backward until it reaches the bottom of the guide groove 62. At this point, the second sealing ring 41 adheres tightly to the annular baffle 11 with a certain pressure, switching to a sealing state. This improved structure allows the sealing element 4 to remain in a ventilated state without requiring continuous pressing, making operation more convenient.

[0069] Specifically, such as Figure 9 As shown, the front end of the locking member 54 is provided with a baffle 543, and the rear end of the spring 52 abuts against the baffle 543, making the spring 52 more stable and preventing the spring 52 from bending or twisting.

[0070] Specifically, such as Figure 9As shown, the baffle 543 is provided with a vent 544, which is staggered from the retaining strip 542. When the gas is slowly released, the gas can pass through the vent 544 and thus over the baffle 543, thereby ensuring smooth gas release.

[0071] Specifically, refer to Figure 2 The first connecting shaft 42 is threadedly connected and fixed to the top cap 51, and the second connecting shaft 532 is threadedly connected and fixed to the sealing component 4. The threaded connection is convenient to operate and easy to disassemble. In other embodiments, the first connecting shaft 42 and the top cap 51, and the second connecting shaft 532 and the sealing component 4 can also be fixed by adhesive, welding or other means.

[0072] The working principle of the multifunctional sealing bottle in this embodiment is as follows:

[0073] When a high concentration needs to be released quickly:

[0074] Tighten the mounting cap 3 to remove it from the main housing 1. At this point, the material is exposed to the air and releases a high concentration of volatile gases.

[0075] When slow release of low concentrations is required:

[0076] Pressing the top cap 51 causes the sealing component 4 and the linkage rod to move forward. At the same time, the guide strip 531 and the locking strip 542 slide forward in the guide groove 62 of the support cylinder 6. When the locking strip 542 disengages from the guide groove 62, the guide groove 62 rotates to the corresponding adjacent guide groove 62 because the inclined surface at the rear end of the guide groove 62 contacts the guide strip 531 and the front side is supported by the spring 52. However, the depth of the adjacent guide groove 62 is not enough for the locking strip 542 to slide in, so the locking strip 542 will be supported at the opening of the guide groove 62. At this time, the locking strip 542 disengages from the guide strip 531, and the guide strip 531 loses the pressure in front, which causes the sealing component 4 to also lose the pressure in front. Finally, the second sealing ring 41 disengages from the annular baffle 11 to form a gap, switching to the ventilation state, and the gas is slowly released through the gap.

[0077] When sealed storage is required:

[0078] The mounting cap 3 at the front end of the sealed bottle is screwed onto the main housing 1, so that the first sealing ring 33 abuts against the front end face of the main housing 1 to achieve a seal. When the external force presses the top cap 51, the top cap 51 drives the sealing component 4 and the linkage rod to move forward. When the locking strip 542 disengages from the guide groove 62, since the inclined surface at the rear end of the guide groove 62 contacts the guide strip 531 and the front side is supported by the spring 52, the guide groove 62 will rotate to the corresponding adjacent guide groove 62. The depth of the adjacent guide groove 62 is sufficient for the locking strip 542 to slide in, so the locking strip 542 will slide into the guide groove 62. At this time, the locking strip 542 abuts against the guide strip 531, and the guide strip 531 obtains the pressure in front, so that the sealing component 4 also obtains the pressure in front, and finally the second sealing ring 41 abuts against the annular baffle 11 with a certain pressure, switching to the sealing state. The front and rear ends of the sealed bottle are sealed, thus completing the sealed storage of materials.

[0079] The above are merely specific embodiments of the present invention, enabling those skilled in the art to understand or implement the present invention. Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and they should all be covered within the protection scope of the claims.
