Description

Technical Field

[0001] This utility model relates to the technical field of coupling agent bottles, and more specifically, it relates to a pollution-proof rotary quantitative extrusion cap for coupling agent bottles. Background Technology

[0002] Coupling agents are substances used to connect different media, enabling the efficient transmission of energy or signals. They have wide applications in medical, industrial, and other fields. There is a difference in acoustic impedance between human tissue and an ultrasound probe. Ultrasonic waves are reflected and refracted at the interface, leading to energy loss and decreased image quality. Medical coupling agents have an acoustic impedance between that of human tissue and the probe, effectively reducing this impedance difference and allowing ultrasound waves to be transmitted more effectively into the body. They also eliminate air between the probe and the skin, reducing ultrasound wave reflection.

[0003] According to the search, coupling agents are packaged in bottles. The coupling agent bottles must meet medical and health standards, be easy to operate with one hand, avoid cross-infection, and have a soft body. The dosage is controlled by squeezing. The deformation of the bottle body is easily changed by the amount of force applied and the bottle material. This makes it impossible to control the coupling agent output at one time and it is easy for it to flow back at the bottle mouth, causing contamination inside the bottle.

[0004] Therefore, a coupling agent bottle anti-contamination rotary quantitative extrusion cap is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a coupling agent bottle anti-pollution rotary quantitative extrusion cap to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coupling agent bottle anti-pollution rotary quantitative extrusion cap, comprising a bottle body, a cap bottom installed on the top of the bottle body, and the inner side of the cap bottom being spiral-shaped; an inner cap installed on the top of the cap bottom; a conveying structure installed on the lower interior of the inner cap; a spiral mechanism installed at the upper edge of the inner cap; an outer cap installed on the top of the spiral mechanism; and the inner cap and the outer cap being spirally connected by the spiral mechanism; an output structure provided on the top of the outer cap; and a sealing air chamber provided on the top of the conveying structure.

[0007] Preferably, a connecting tube is installed at the center of the bottom of the cap, the lower part of the connecting tube extends into the interior of the bottle body, and the end of the connecting tube away from the bottle body extends into the interior of the conveying structure.

[0008] Preferably, the spiral mechanism includes a thread, a washer, a second spring, a push rod, a card, a card block, and a card slot. A push rod is installed on one side of the card slot, and a card is installed above the push rod. The push rod is connected to the second spring on the side away from the card slot, and the push rod passes through the second spring and the outer cover. A washer is installed on one side of the second spring, and the washer is installed on the inner wall of the outer cover. A button is installed on the outer side of one side of the outer cover.

[0009] Preferably, the inner cover and the outer cover are connected by threads on the same side, and the threads are provided with slots between the threads, and the distance between two adjacent slots 507 is the same. A locking block is installed inside the slot, and the slot is located on the outer wall of the inner cover.

[0010] Preferably, the conveying structure includes a support body, a movable air chamber, a movable plate, a sealing plug, a pressure valve, and a conduit. A pressure valve is installed at the center of the movable plate, and a conduit is installed above the pressure valve. The conduit is fixedly connected to the outer cover, and the interior of the movable air chamber is a sealed structure.

[0011] Preferably, the bottom of the inner cover is equipped with two support columns, and a first spring is wound around the outside of each support column. A support body is installed above the first spring, and a movable air chamber is provided above the support body.

[0012] Preferably, the outer cover includes an upper air chamber, a movable block, a lower air chamber, a liquid outlet, and a latex head. The end of the conduit away from the pressure valve extends into the interior of the upper air chamber. The movable block is installed below the upper air chamber, and the lower air chamber is located below the movable block. Multiple air guide pipes are installed below the lower air chamber.

[0013] Preferably, the spatial deformation of the upper air chamber is 1 / 4 to 1 / 3 of the internal spatial deformation of the active air chamber.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] Compared with existing technologies, this anti-contamination rotary quantitative extrusion cap for coupling agent bottles uses external force to drive the outer cap, causing it to rotate along the threaded spiral. Simultaneously, the movable plate moves up and down following the rotation of the outer cap. During the rotation, the height of rotation is determined by a slot, thus ensuring that the vertical movement distance of the movable plate is limited by the position of the slot. By limiting the displacement of the movable plate, the volume of the movable gas chamber is controlled, making the amount of coupling agent contained and output by the output mechanism controllable.

[0016] Compared with existing technologies, this anti-contamination rotary quantitative extrusion cap for coupling agent bottles uses a method where squeezing the bottle body allows the coupling agent to enter the movable air chamber, and squeezing the support body downwards reduces the pressure inside the sealed air chamber. This causes the movable block to move downwards under atmospheric pressure. Simultaneously, the coupling agent flows into the upper air chamber from the output mechanism under pressure. When the force squeezing the bottle body is removed, the bottle body returns to its original shape, and the support body moves upwards under the action of a spring, restoring the pressure inside the sealed air chamber. The movable block then moves upwards, driving the coupling agent out of the upper air chamber and sealing the outlet, ensuring complete isolation between the inside and outside and preventing contamination.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0024] As attached Figures 1 to 5The embodiment shown is a coupling agent bottle anti-contamination rotary quantitative extrusion cap, comprising a bottle body 1, a cap bottom 2 installed on the top of the bottle body 1, the inner side of the cap bottom 2 being spiral-shaped, an inner cap 3 installed on the top of the cap bottom 2, a conveying structure 7 installed on the lower interior of the inner cap 3, a spiral mechanism 5 installed on the upper edge of the inner cap 3, an outer cap 4 installed on the top of the spiral mechanism 5, and the inner cap 3 and the outer cap 4 being spirally connected by the spiral mechanism 5. An output structure 6 is provided above the outer cap 4, and a sealing air chamber 10 is provided above the conveying structure 7. The outer cap 4 rotates around the inner cap 3 under external force and moves vertically under the action of the spiral mechanism 5. At the same time, the vertical movement of the outer cap 4 is controlled by the spiral mechanism 5. The inner cap 3 is connected to the bottle body 1 through the cap bottom 2. Squeezing the bottle body 1 causes the coupling agent to enter the inner cap 3 under pressure.

[0025] A connecting pipe 8 is installed at the center of the bottom cap 2. The lower part of the connecting pipe 8 extends into the interior of the bottle body 1, and the end of the connecting pipe 8 away from the bottle body 1 extends into the interior of the conveying structure 7. By pressing the bottle body 1, the coupling agent passes through the connecting pipe 8 and enters the interior of the conveying mechanism 7 through the connecting pipe 8.

[0026] The spiral mechanism 5 includes a thread 501, a washer 502, a second spring 503, a push rod 504, a card 505, a locking block 506, and a slot 507. The push rod 504 is mounted on one side of the slot 507, and the card 505 is mounted above the push rod 504. The side of the push rod 504 away from the slot 507 is connected to the second spring 503, and the push rod 504 passes through the second spring 503 and the outer cover 4. The washer 502 is mounted on one side of the second spring 503 and is installed on the inner wall of the outer cover 4. A button 508 is mounted on the outer side of one side of the outer wall of the outer cover 4. Before the outer cover 4 moves, press button 508 to store force in the second spring 503. At the same time, the pressure generated by the stored force of the second spring 503 acts on the push rod 504, causing the push rod 504 to press into the groove of the slot 507. When the outer cover 4 rotates under force, the outer cover 4 moves up and down along the spiral direction of the slot 507, and drives the push rod 504 to follow the movement of the outer cover 4. When the push rod 504 rotates to the top of the slot 507, the push rod 504 enters the slot 507 under pressure and is restricted by the locking block 506, thereby restricting the rotational displacement of the outer cover 4 by the slot 507.

[0027] The inner cover 3 and the outer cover 4 are connected by threads 501 on the same side. The threads 501 are connected by slots 507, and the distance between two adjacent slots 507 is the same. A block 506 is installed inside the slot 507. Since the distance between two adjacent slots 507 is the same, the push rod 504 inside the outer cover 4 rotates through the same distance between two adjacent slots 507, thereby limiting the displacement of the outer cover 4 according to the position of the slot 507.

[0028] The conveying structure 7 includes a support body 701, a movable air chamber 702, a movable plate 703, a sealing plug 704, a pressure valve 705, and a conduit 706. The pressure valve 705 is installed at the center of the movable plate 703, and the conduit 706 is installed above the pressure valve 705. The conduit 706 is fixedly connected to the outer cover 4. The interior of the movable air chamber 702 is a sealed structure. Because the outer cover 4 is fixedly connected to the conduit 706, and the conduit 706 is connected to the movable plate 703 via the pressure valve 705, when the outer cover 4 is driven by an external force and moves vertically, the movable plate 703 follows the outer cover 4 in a consistent manner. The movement of the movable plate 703 causes the volume of the sealed movable air chamber 702 to change accordingly, thereby causing the volume of the coupling agent entering the movable air chamber 702 through the connecting pipe 8 to change simultaneously. Since the push rod 504 inside the outer cover 4 rotates through the same distance between two adjacent slots 507, the volume of the movable air chamber 702 corresponding to each slot 507 is fixed, thus controlling the amount of coupling agent filling the movable air chamber 702. When the movable air chamber 702 is filled with coupling agent, the pressure valve 705 opens under the squeezing action of the coupling agent, and the coupling agent enters the conduit 706 through the pressure valve 705.

[0029] The outer cover 4 includes an upper air chamber 401, a movable block 402, a lower air chamber 403, a liquid outlet 404, and a latex head 405. The end of the conduit 706 away from the pressure valve 705 extends into the interior of the upper air chamber 401. The movable block 402 is installed below the upper air chamber 401, and the lower air chamber 403 is located below the movable block 402. Multiple air guide tubes 9 are installed below the lower air chamber 403. When the movable air chamber 702 is filled with coupling agent, the pressure valve 403 opens under pressure, allowing the coupling agent to enter the conduit 404 through the pressure valve 403 and then enter the interior of the upper air chamber 405 through the conduit 404. When the coupling agent fills the interior of the upper air chamber 405, it enters the liquid outlet 408 and is output through the latex head 409 connected to the liquid outlet 408.

[0030] The inner cover 3 has two support pillars 301 installed at its bottom. A first spring 302 is wound around the outer side of each support pillar 301. A support body 701 is installed above the first spring 302, and a movable air chamber 702 is located above the support body 701. When the coupling agent enters through the connecting pipe 8 and fills the movable air chamber 702, the coupling agent compresses the support body 701 below the movable air chamber 702 and the pressure valve 403 above it, causing the support body 701 to move downwards and compress the first spring 302. The movement of the support body 701 is restricted by the support pillars 301 below. Simultaneously, the downward movement of the support body 701 increases the volume of the sealed space inside the sealed air chamber 10. The pressure inside the sealed air chamber 10 decreases as the pressure increases. Since the sealed air chamber 10 is connected to the lower air chamber 403 through the air guide pipe 9, the movable block 406 located above the lower air chamber 403 moves downward under atmospheric pressure. After the bottle body 1 is squeezed, the bottle body 1 returns to its original shape, the coupling agent flows back, and the support body 701 moves upward under the action of the first spring 302. At the same time, the volume of the sealed space inside the sealed air chamber 10 decreases, which leads to an increase in the pressure inside the sealed air chamber 10. This causes the movable block 406 to move upward under the action of the pressure difference and squeeze the residual coupling agent in the upper air chamber 9 to be discharged. At the same time, the coupling agent inside the bottle is isolated to prevent the coupling agent from being contaminated.

[0031] The spatial deformation of the upper air chamber 401 is 1 / 4 to 1 / 3 of the internal spatial deformation of the active air chamber 702. The difference in deformation between the upper air chamber 401 and the active air chamber 702 ensures that the coupling agent flowing out of the active air chamber 702 completely fills the upper air chamber 401, thereby ensuring the smooth discharge of the coupling agent.

[0032] The working process of this utility model is as follows: In use, firstly, the outer cover 4 is driven to rotate along the thread 501, and the second spring 503 is compressed by the control button 508, so that the second spring 503 pushes the push rod 504, so that the push rod 504 generates inward pressure. When the push rod 504 rotates with the outer cover 4, it engages with the slot 507, and the distance between two adjacent slots 507 is the same, so that the outer cover 4 moves the same distance when passing through two adjacent slots 507, thereby controlling the moving distance of the outer cover 4, and then controlling the displacement of the conduit 706 and the movable plate 704 installed below the outer cover 4. At the same time, the moving distance of the movable plate 704 changes the volume inside the movable air chamber 702, making the volume of the movable air chamber 702 controllable, thereby controlling the volume of the coupling agent flowing into the movable air chamber 702, and ensuring that the amount of coupling agent output by the output mechanism 7 is controllable.

[0033] Then, by pressing the bottle body 1, the coupling agent is forced through the connecting tube 8 and into the interior of the active air chamber 702. When the coupling agent fills the interior of the active air chamber 702, it compresses the support body 701 to move downward and compresses the first spring 302. When the support body 701 moves above the support column 301, it stops compressing the first spring 302 and begins to squeeze the pressure valve 403, causing the pressure valve 403 to open. The coupling agent enters the output structure 6 through the pressure valve 403. At the same time, the support body 701 moves downward, increasing the volume inside the sealed air chamber 10 and decreasing the pressure. Under atmospheric pressure, the active block 402 squeezes the lower air chamber 403.

[0034] Secondly, the coupling agent enters the upper air chamber 405 through the conduit 404 and enters the latex head 409 through the liquid outlet 408, thereby discharging the coupling agent.

[0035] Finally, the squeezing ends, the bottle body 1 returns to its original shape, the coupling agent flows back, causing the support body 701 to move upward under the action of the first spring 302. At the same time, the volume inside the sealed air chamber 10 decreases, the pressure increases, and the pressure difference drives the movable block 406 to move upward, squeezing out the residual coupling agent in the upper air chamber 401 and isolating the coupling agent inside the bottle to prevent the coupling agent from being contaminated.
