Abstract
Description
Technical Field
[0001] This application relates to the field of medical and nursing auxiliary equipment technology, and in particular to a fire extinguishing bucket specifically for cupping ignition sticks. Background Technology
[0002] Cupping therapy is an important component of external therapies in Traditional Chinese Medicine. It applies negative pressure to acupoints or specific areas of the body, effectively promoting blood circulation and relieving muscle pain, and is widely used in clinical practice and daily health maintenance. During cupping, a ignition stick is a commonly used tool to quickly burn an alcohol-soaked cotton ball inside the cup to create negative pressure. However, the extinguishing process after using the ignition stick presents significant safety hazards and operational inconveniences, becoming a long-standing pain point in the industry.
[0003] In traditional cupping procedures, medical staff typically use simple containers (such as water cups or metal cans) to extinguish the used ignition rod. These containers generally have the following drawbacks:
[0004] Firstly, the open structure cannot effectively isolate oxygen, which may cause the combustion residue to reignite, especially when the alcohol is not completely extinguished, posing a risk of igniting an open flame.
[0005] Secondly, the operation of a typical closed fire extinguishing container requires frequent opening and closing of the container lid, which not only increases the number of steps but also makes the operation very inconvenient because opening and closing the container lid requires both hands, and the cupping operator usually holds the cup in one hand and the ignition stick in the other.
[0006] In summary, existing cupping ignition rod fire extinguishing devices still have significant shortcomings in terms of safety, ease of operation, and structural reliability. There is an urgent need for a dedicated fire extinguishing device that can achieve rapid one-handed operation and ensure reliable fire extinguishing for cupping ignition rod fire extinguishing. Utility Model Content
[0007] The purpose of this application is to propose a special fire extinguishing bucket for cupping ignition rods, which solves the problem that the operation of general closed fire extinguishing containers requires frequent opening and closing of the container lid, which not only increases the operation steps, but also makes the operation very inconvenient because opening and closing the container lid requires two hands.
[0008] To achieve the above objectives, this application adopts the following technical solution:
[0009] A special fire extinguishing bucket for cupping with an ignition stick includes: a container body having a receiving cavity with an inlet; a cover covering the inlet, the cover having a perforated feeding port communicating with the receiving cavity; a movable cover movably fitted onto the feeding port, the outer periphery of the movable cover fitting with the inner periphery of the feeding port, and a first notch near the outer edge of the movable cover; and a connecting device including a connecting arm, one end of which is hinged to the cover body and the other end to the movable cover, the connecting arm being able to move away from or into the feeding port by swinging it, the axis of hinge between the connecting arm and the movable cover being offset from the first notch.
[0010] Based on the above solution and as a preferred embodiment of the above solution: the connecting arm includes two connecting rods arranged opposite each other, the two connecting rods are respectively located on one side of the movable cover, one end of the two connecting rods is connected to each other through a first rotating shaft, and the other end is connected to each other through a second rotating shaft; the first rotating shaft is rotatably connected to the cover body through a first hinge lug provided on the cover body; the second rotating shaft is rotatably connected to the movable cover through a second hinge lug provided on the movable cover.
[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the first rotating shaft is fixedly connected to both of the two connecting rods and rotates with the first connecting ear; an iron block is fixedly installed on the first rotating shaft; a connecting block is fixedly installed on the cover, and a magnet is installed on the connecting block. After the connecting arm is swung away from the feeding port, the magnet can attract the iron block.
[0012] Based on the above scheme and as a preferred embodiment of the above scheme: the feeding port includes a cut hole and an annular extension extending upward around the cut hole.
[0013] Based on the above scheme and as a preferred embodiment of the above scheme: a second notch is provided on the annular extension body, the second notch being adjacent to the first notch and corresponding to the position of the first notch.
[0014] Based on the above scheme and as a preferred embodiment of the above scheme: the annular extension body is provided with two third notches, the two third notches correspond to the positions of the second rotating shaft, and when the movable cover is inserted into the feeding port, the second rotating shaft is inserted into the third notch and supported by the bottom of the third notch.
[0015] Based on the above scheme and as a preferred embodiment of the above scheme: the feeding port is circular and the movable cover is circular.
[0016] Based on the above scheme and as a preferred embodiment of the above scheme: a counterweight block is provided at the center of the lower side of the movable cover.
[0017] Based on the above scheme and as a preferred embodiment of the above scheme: a limiting block is provided in the feeding port, which is located on the side away from the first notch, and the limiting block is located on the lower side of the movable cover; a counterweight is provided on the lower side of the movable cover, and the counterweight is offset from the axis of hinge between the connecting arm and the movable cover in the direction away from the first notch.
[0018] Based on the above scheme and as a preferred embodiment of the above scheme: the tank body is provided with a U-shaped handle, and the two ends of the U-shaped handle are respectively rotatably connected to the two sides of the tank body.
[0019] To address the problem that the operation of conventional closed fire extinguishing containers requires frequent opening and closing of the container lid, which not only increases the number of steps but also makes the operation inconvenient as it requires both hands, this application offers the following advantages:
[0020] The fire extinguishing bucket for cupping ignition rods in this application is mainly used for fire extinguishing operations after the use of cupping ignition rods.
[0021] This cupping ignition stick fire extinguisher is equipped with a body, a lid, and a movable lid. When using it, hold the end of the ignition stick away from the alcohol cotton ball, align the alcohol cotton ball with the side of the movable lid with the first notch, and then apply downward force. The alcohol cotton ball will push the movable lid to rotate around the axis of the connecting arm and the hinge of the movable lid. When rotating, the side of the movable lid with the first notch will rotate downward and expose part of the feeding port on the lid. Then continue to apply downward force and push the alcohol cotton ball downward so that the alcohol cotton ball passes through the feeding port and enters the receiving cavity. At this point, because the movable cover loses the thrust constraint of the alcohol cotton ball, it begins to rotate and reset under its own weight. Since the hinge point between the movable cover and the connecting arm is located on the upper middle side of the movable cover (i.e., the hinge axis is above the center of gravity of the movable cover), the movable cover rotates and resets until its outer circumference aligns with the inner circumference of the feeding port, creating a relatively sealed state. At this point, through manual control, the extension rod of the ignition rod is positioned precisely within the first notch. Because the alcohol cotton ball in the ignition rod is sealed within the cavity, it will quickly extinguish automatically due to insufficient oxygen supply for combustion.
[0022] The above-mentioned fire extinguishing process with the ignition stick can be completed with just one hand, and there is no need to use your hands specifically to open and close the lid. The operation is very simple and convenient.
[0023] In addition to the purposes, features, and advantages described above, this application has other purposes, features, and advantages. These will be further described in detail below with reference to figures. Attached Figure Description

[0039] See Figure 1-5 This application discloses a special fire extinguisher for cupping ignition rods. This fire extinguisher is mainly used for extinguishing fires after the use of the cupping ignition rod 500. The ignition rod 500 is as follows... Figure 6 As shown, it generally includes a handle 501, an extension rod 502 set on the handle 501, and an alcohol swab 503 set at the end of the extension rod 502 away from the handle 501.
[0040] In the embodiments of this disclosure, such as Figure 1 and Figure 3As shown, the special fire extinguishing bucket for cupping ignition includes a container body 100, a lid 200, and a movable lid 300. The container body 100 is provided with an open-top receiving cavity 101, and the open end of the receiving cavity 101 is the inlet 102. The lid 200 is positioned on top of the tank 100 and covers the inlet 102. Generally, the lid 200 and the tank 100 are detachable. For example, the outer periphery of the lid 200 may have a downward-facing folded edge 201. When the lid 200 covers the inlet 102 of the tank 100, the folded edge 201 fits precisely against the outer periphery of the upper part of the tank 100. The detachable connection is achieved through frictional engagement between the folded edge 201 and the outer periphery of the upper part of the tank 100. The lid 200 has a perforated feeding port 202. After the lid 200 is placed on the tank 100 (completely closed), the feeding port 202 is positioned directly above the receiving cavity 101. A movable cover 300 is movably fitted onto the feeding port 202. The outer periphery of the movable cover 300 fits into the inner periphery of the feeding port 202. A first notch 301 is provided near the outer edge of the movable cover 300. The connecting device 400 includes a connecting arm 401, one end of which is hinged to the cover 200, and the other end is hinged to the upper middle part of the movable cover 300. This allows the center of gravity of the movable cover 300 to be offset downward relative to the axis of hinge between the connecting arm 401 and the movable cover 300, forming a "pendulum" characteristic. This allows the movable cover 300 to maintain a relatively horizontal posture under its own weight. By swinging the connecting arm 401, the connecting arm 401 can be moved away from or inserted into the feeding port 202. After the movable cover 300 is inserted into the feeding port 202, since the movable cover 300 is relatively horizontal in its own state, a relatively "sealed" fit is formed between the movable cover 300 and the feeding port 202. The axis of hinge between the connecting arm 401 and the movable cover 300 is offset from the first notch 301. The first notch 301 is preferably located on the central axis of the movable cover 300, which is perpendicular to the axis of hinge between the connecting arm 401 and the movable cover 300.
[0041] When using this cupping ignition rod 500 to extinguish a fire, the operator holds the handle 501 of the ignition rod 500, aligns the alcohol cotton ball 503 with the side of the movable cover 300 where the first notch 301 is located, and then applies downward force. The alcohol cotton ball 503 pushes the movable cover 300 to rotate around the axis of hinge between the connecting arm 401 and the movable cover 300. During rotation, the side of the movable cover 300 with the first notch 301 rotates downward and exposes part of the feeding port 202 on the cover body 200. Then, the operator continues to apply downward force and pushes the alcohol cotton ball 503 downward, so that the alcohol cotton ball 503 passes through the feeding port 202 and the inlet 102 and enters the receiving cavity 101. At this point, since the movable cover 300 loses the thrust constraint of the alcohol cotton ball 503, it begins to reset and rotate under its own gravity. Because the hinge point between the movable cover 300 and the connecting arm 401 is on the upper side of the middle of the movable cover 300, that is, the axis of hinge between the connecting arm 401 and the movable cover 300 is directly above the center of gravity of the movable cover 300, the movable cover 300 begins to reset and rotate under its own gravity until the outer periphery of the movable cover 300 and the inner periphery of the feeding port 202 are in a relatively sealed state. Figure 5 As shown, at this time, through manual control, the extension rod 502 of the ignition rod 500 is positioned exactly in the first notch 301. Since the alcohol cotton ball 503 of the ignition rod 500 is in a closed state within the receiving cavity 101, it will soon automatically extinguish due to insufficient oxygen supply for combustion.
[0042] The operation of the above-mentioned ignition rod 500 can be completed with just one hand, and there is no need to use your hands to open and close the lid. The operation is very simple and convenient. At the same time, due to its ease of operation, it also avoids the risk of the container tipping over due to accidental contact during the operation of general closed fire extinguishing containers.
[0043] It is important to note that the seal between the movable cover 300 and the cover body 200 and the internal cavity 101 of the tank 100 is a relatively sealed state that allows the alcohol cotton ball 503 to extinguish itself due to lack of oxygen during combustion. A small gap may exist between the movable cover 300 and the feeding port 202, rather than an absolute seal that establishes a vacuum. Extinguishing the alcohol cotton ball 503 by creating a closed space is a standard practice that complies with operational safety regulations.
[0044] Furthermore, in order to facilitate the setting and take into account the coordination requirements between the movable cover 300 and the feeding port 202 during operation, the feeding port 202 is circular, and the movable cover 300 is circular.
[0045] In the embodiments of this disclosure, such as Figure 4As shown, considering the efficiency during the reset rotation of the movable cover 300 and its stability during long-term use, a counterweight 302 is provided at the center of the side of the movable cover 300 facing away from the connecting device 400. By setting the counterweight 302, the center of gravity (weight) is adjusted, thereby improving the constraint force of automatic reset. In this case, the counterweight 302 is preferably located directly below the axis of hinge between the connecting arm 401 and the movable cover 300.
[0046] Furthermore, such as Figure 4 As shown, a limiting block 203 is provided in the feeding port 202, located on the side away from the first notch 301. The limiting block 203 is located on the lower side of the movable cover 300, and a counterweight 302 is provided on the lower side of the movable cover 300. At this time, the counterweight 302 is offset from the axis of hinge between the connecting arm 401 and the movable cover 300 in the direction away from the first notch 301. When the movable cover 300 is pushed to move, the side of the movable cover 300 near the limiting block 203 swings upward. Then, during the reset process of the movable cover 300, the side of the limiting block 203 swings downward and is supported by the limiting block 203 to complete the reset. Due to the offset of the counterweight 302 towards the limiting block 203, the reset process of the movable cover 300 is faster and more stable.
[0047] Furthermore, a stop bar 204 can be provided on the cover 200. The stop bar 204 is located on the lower side of the movable cover 300 to constrain the center of gravity of the movable cover 300 from crossing the axis of hinge between the connecting arm 401 and the movable cover 300 during the opening and moving process. This ensures that the movable cover 300 can stably swing the side away from the first notch 301 toward the direction of the limit block 203 during the automatic reset process each time.
[0048] In the embodiments of this disclosure, such as Figure 1 and Figure 5 As shown, a U-shaped handle 103 is provided on the canister body 100, and the two ends of the U-shaped handle 103 are rotatably connected to the two sides of the canister body 100 respectively. When it is necessary to move this special fire extinguisher for cupping ignition, the U-shaped handle 103 can be held by hand to lift the entire special fire extinguisher for cupping ignition to change its position.
[0049] In this embodiment of the disclosure, to support the operational requirements and reliability of the connection device 400, such as Figure 1-4As shown, the connecting arm 401 includes two parallel connecting rods 402 arranged opposite each other. The two connecting rods 402 are respectively located on one side of the movable cover 300 (i.e., one connecting rod 402 is provided on each side of the movable cover 300). One end of each connecting rod 402 is connected to the other through a first rotating shaft 403 (i.e., the two ends of the first rotating shaft 403 are respectively connected to one end of a connecting rod 402), and the other end is connected to the other through a second rotating shaft 405 (i.e., the two ends of the second rotating shaft 405 are respectively connected to one end of a connecting rod 402). The first rotating shaft 403 is rotatably connected to the cover 200 through a first hinge ear 205 provided on the cover 200, and the second rotating shaft 405 is rotatably connected to the movable cover 300 through a second hinge ear 303 provided on the movable cover 300.
[0050] Furthermore, the first rotating shaft 403 is fixedly connected to both connecting rods 402 and rotatably engages with the first connecting lug; the second rotating shaft 405 can selectively rotatably engage with either the second hinge lug 303 or the connecting rod 402, or simultaneously rotatably engage with both the second hinge lug 303 and the connecting rod 402. An iron block 404 is fixedly mounted on the first rotating shaft 403; a connecting block 206 is fixedly mounted on the cover 200, and a magnet 207 is mounted on the connecting block 206. After swinging the connecting arm 401 to move it away from the feeding port 202, as... Figure 4 As shown, the magnet 207 can attract the iron block 404. After attraction, the magnet 207 can connect the arm 401 to the current posture through the engagement position of the iron block 404, so that the can 100 can remain in the open state.
[0051] Furthermore, the feeding port 202 includes a hollowed-out cut hole 211 and an annular extension 208 extending upward around the cut hole 211. The inner hole of the annular extension 208 and the inner hole of the cut hole 211 together constitute the feeding port 202. The annular extension 208 can form a protective area that extends upward at one end and surrounds the movable cover 300, which can avoid the risk of sparks splashing out during the process of the ignition rod 500 being inserted into the receiving cavity 101, and further reduce the risk of safety hazards to the operator or the surrounding environment.
[0052] Furthermore, such as Figure 5 As shown, the annular extension 208 has a second notch 209, which is adjacent to and corresponds to the first notch 301, meaning the opening direction of the second notch 209 is directly opposite to that of the first notch 301. During the placement of the ignition rod 500, the extension rod 502 can be positioned within the second notch 209. Thus, after the movable cover 300 is reset, the first notch 301 can be precisely engaged with the extension rod 502.
[0053] Furthermore, the annular extension 208 is provided with two third notches 210, which are located on both sides of the annular extension 208. The two third notches 210 correspond to the positions of the second rotating shaft 405. When the movable cover 300 is inserted into the feeding port 202, as... Figure 2 As shown, the second pivot 405 is embedded in the third notch 210 and is supported by the bottom of the third notch 210.
[0054] When it is necessary to remove the extinguished ignition rod 500, simply pull it upwards from the feeding port 202.
[0055] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
