Description

Technical Field

[0001] This utility model relates to the technical field of ointment extrusion devices, specifically an ointment extrusion device. Background Technology

[0002] Ointments are widely used viscous semi-solid preparations, commonly found in pharmaceuticals, cosmetics, industrial lubrication, and sealing. They are typically composed of an active ingredient mixed with an excipient matrix (such as petrolatum, waxes, or polymeric gels), and have high viscosity and poor flowability, requiring storage and use in tubular or cylindrical containers.

[0003] Currently, the mainstream methods for extruding ointments include manual direct squeezing and using a simple gear-type extruder. For manual squeezing, the user applies pressure directly to the ointment tube or reservoir by hand, forcing the contents out of the outlet. For more viscous ointments or to save on excess product, mechanical extruders are often used, which typically use a rotating screw or rack and pinion mechanism to push a baffle, thereby squeezing the ointment tube.

[0004] However, the aforementioned existing technologies have significant drawbacks. First, manual squeezing is laborious and makes it difficult to control the extrusion volume and speed, leading to waste or inaccurate dosage; it is particularly unfriendly to users with hard-packed ointments or those lacking sufficient hand strength. Second, while traditional mechanical ointment squeezers can save labor, they generally suffer from inconvenient installation and fixing of ointment tubes, cumbersome replacement, and their propulsion mechanisms often lack precise linear guidance, potentially causing instability in the squeezing process and resulting in inconsistent ointment extrusion. More importantly, most existing devices are single-function and cannot simultaneously meet multiple optimization needs such as quick assembly and disassembly, stable propulsion, and quantitative control, leaving room for improvement in user experience. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing manual extrusion methods, which are laborious and difficult to control in terms of extrusion volume and speed, leading to waste or inaccurate dosage. This is particularly inconvenient for users with hard-packed ointments or insufficient hand strength. The proposed ointment extrusion device features a quick-release mechanism that, through the cooperation of a button, an inclined second slide, and a spring, enables one-handed, quick, and tool-free assembly and disassembly of the storage mechanism, with reliable locking. This significantly improves operational convenience and ointment replacement efficiency. Furthermore, the extrusion mechanism employs a motor-driven gear set and screw transmission, providing stable, uniform, and strong linear thrust under the constraint of a guide rod, effectively overcoming the problems of uneven and laborious manual extrusion.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design an ointment extrusion device, including a support mechanism, a storage mechanism, an extrusion mechanism, and a quick-connect mechanism. The support mechanism includes a first mounting plate. The storage mechanism includes a storage cylinder for storing ointment and a piston movably installed inside the storage cylinder. The extrusion mechanism is disposed on the support mechanism and is used to drive the piston to move inside the storage cylinder to extrude ointment. The quick-connect mechanism is disposed on the support mechanism. The storage mechanism is detachably installed on the top of the support mechanism via the quick-connect mechanism, so that the output end of the extrusion mechanism can act on the piston.

[0007] Furthermore, the quick-installation mechanism includes a mounting base, a locking component, and an unlocking button. The mounting base is fixed to the first mounting plate. The locking component is installed in the mounting base and has a locking state in which it tends to open under the action of an elastic element to lock the material storage mechanism, and an unlocking state in which it contracts to release the material storage mechanism when compressed. The unlocking button is slidably installed on the mounting base and connected to the locking component to drive the locking component from the locking state to the unlocking state.

[0008] Furthermore, the mounting base includes a mounting shell, a connecting piece fixed to the top of the mounting shell, and a second mounting plate fixed to the top of the connecting piece. The locking assembly includes two sets of symmetrically arranged mounting rods. One end of each mounting rod is provided with a locking head. The second mounting plate has a first sliding groove for the mounting rod to slide. The elastic element is a spring, which is disposed inside the connecting piece and connected at both ends to the two sets of mounting rods respectively, so that the two sets of locking heads are normally far apart from each other. The bottom of the storage cylinder of the storage mechanism is fixedly installed with a locking sleeve that cooperates with the locking head.

[0009] Furthermore, the unlocking button includes a third mounting plate and a button fixed to one side thereon. The third mounting plate is slidably mounted on the outer wall of the connecting piece through a third sliding groove opened inside it. The third mounting plate also has two sets of symmetrical second sliding grooves inside it. A sliding rod is fixed on the mounting rod. One end of the sliding rod is slidably mounted in the first sliding groove, and the other end is slidably mounted in the corresponding second sliding groove. The second sliding groove is an inclined sliding groove, which is configured such that when the button is pressed and the third mounting plate is slid downward, the sliding rod forces the two sets of mounting rods to move closer to each other along the first sliding groove, thereby causing the latch to disengage from the locking sleeve.

[0010] Furthermore, the extrusion mechanism includes a mounting bracket fixed to the first mounting plate, a motor mounted on the mounting bracket, a gear set driven by the motor, and a screw threadedly engaged with the gear set, the end of the screw being provided with an extrusion head for pushing the piston.

[0011] Furthermore, the gear set includes a first gear fixedly connected to the output shaft of the motor, and a second gear meshing with the first gear. The second gear has a threaded hole inside, and the screw is threadedly engaged with the threaded hole. At least one guide rod is fixed on the mounting bracket, and the screw has a guide part that cooperates with the guide rod, so that the screw can only move in a straight line when the second gear rotates.

[0012] Furthermore, the support mechanism also includes a handle fixed to the bottom of the first mounting plate, and a control button on the handle for controlling the start and stop of the extrusion mechanism. A fixing head is fixedly installed on one side of the storage cylinder, and an extrusion head or sealing head is threadedly connected to the fixing head.

[0013] The ointment extrusion device proposed in this utility model has the following advantages: The quick-assembly mechanism, through the cooperation of a button, an inclined second slide, and a spring, enables one-handed, quick, and tool-free assembly and disassembly of the material storage mechanism, with reliable locking, greatly improving the convenience of operation and the efficiency of ointment replacement. Secondly, the extrusion mechanism adopts a transmission method of motor-driven gear set and screw, and provides stable, uniform, and strong linear thrust under the constraint of the guide rod, effectively overcoming the problems of uneven and laborious manual extrusion, and realizing quantitative and controllable extrusion of ointment. In addition, the ergonomic handle and control button make operation more comfortable and safe, while the replaceable design of the extrusion head and sealing head enhances the versatility and sealing of the device.

[0020] See Figures 1-4 An ointment extrusion device includes a support mechanism 1, a storage mechanism 2, an extrusion mechanism 3, and a quick-release mechanism 4. The support mechanism 1 includes a first mounting plate 101. The storage mechanism 2 includes a storage cylinder 201 for storing ointment and a piston 202 movably installed in the storage cylinder 201. The extrusion mechanism 3 is disposed on the support mechanism 1 and is used to drive the piston 202 to move in the storage cylinder 201 to extrude ointment. The quick-release mechanism 4 is disposed on the support mechanism 1. The storage mechanism 2 is detachably installed on the top of the support mechanism 1 through the quick-release mechanism 4, so that the output end of the extrusion mechanism 3 can act on the piston 202. The quick-release mechanism 4 includes a mounting base, a locking assembly, and an unlocking button. The mounting base is fixed to the first mounting plate 101. The locking assembly is installed inside the mounting base and has a locked state where it tends to open under the action of an elastic element to lock the material storage mechanism 2, and an unlocked state where it contracts to release the material storage mechanism 2 when compressed. The unlocking button is slidably mounted on the mounting base and connected to the locking assembly, used to drive the locking assembly from the locked state to the unlocked state. The mounting base includes a mounting shell 401, a connecting piece 404 fixed to the top of the mounting shell 401, and a connecting piece 404 fixed to the top of the connecting piece 401. The second mounting plate 402 at the top has a locking assembly including two sets of symmetrically arranged mounting rods 409. One end of each mounting rod 409 has a locking head 410. The second mounting plate 402 has a first sliding groove 403 for the mounting rods 409 to slide. The elastic element is a spring 412, which is located inside the connecting piece 404 and is connected to the two sets of mounting rods 409 at both ends, so that the two sets of locking heads 410 are normally far apart. The bottom of the storage cylinder 201 of the storage mechanism 2 is fixedly installed with a locking sleeve 413 that cooperates with the locking head 410. The unlocking button includes a third mounting plate 405 and a locking sleeve 413 fixed to it. A button 406 is located on one side. The third mounting plate 405 is slidably mounted on the outer wall of the connecting piece 404 via a third sliding groove 408 formed inside it. The third mounting plate 405 also has two sets of symmetrical second sliding grooves 407 inside it. A sliding rod 411 is fixed on the mounting rod 409. One end of the sliding rod 411 is slidably mounted in the first sliding groove 403, and the other end is slidably mounted in the corresponding second sliding groove 407. The second sliding groove 407 is an inclined sliding groove, which is configured such that when the button 406 is pressed and the third mounting plate 405 slides downward, the sliding rod 411 forces the two sets of mounting rods 409 to slide downward. 9. The first slide groove 403 moves closer to each other, so that the clamp 410 disengages from the locking sleeve 413. When the button 406 is pressed, the third mounting plate 405 moves down, and its inclined second slide groove 407 squeezes the slide rod 411, forcing the two sets of mounting rods 409 to overcome the elastic force of the spring 412 and slide towards the center along the first slide groove 403 to unlock. After the button 406 is released, the restoring force of the spring 412 causes the clamp 410 to open outward and automatically engage with the locking sleeve 413 to complete the locking. Its function is to realize the one-handed, quick, tool-free assembly and disassembly of the material storage mechanism 2, and to ensure that the connection is firm and reliable in the working state. The extrusion mechanism 3 includes a mounting bracket 301 fixed to a first mounting plate 101, a motor 302 mounted on the mounting bracket 301, a gear set driven by the motor 302, and a screw 305 threadedly engaged with the gear set. The end of the screw 305 is provided with an extrusion head 306 for pushing the piston 202. The gear set includes a first gear 303 fixedly connected to the output shaft of the motor 302, and a second gear 304 meshing with the first gear 303. The second gear 304 has a threaded hole inside, and the screw 305 is threadedly engaged with the threaded hole. The mounting bracket 301... At least one guide rod is fixed on the screw 305, and a guide part that cooperates with the guide rod is provided on the screw 305, so that the screw 305 can only move in a straight line when the second gear 304 rotates. After the motor 302 reduces speed and increases torque through the gear set, it drives the second gear 304 to rotate. Since the screw 305 is restricted from rotating by the guide rod, it can only move in a straight line in the threaded hole of the second gear 304, thereby pushing the piston 202. Its function is to provide a stable, controllable and powerful thrust to achieve uniform and quantitative extrusion of ointment, and overcome the problems of uneven and laborious manual extrusion. The support mechanism 1 also includes a handle 102 fixed to the bottom of the first mounting plate 101, and a control button 103 on the handle 102 for controlling the start and stop of the extrusion mechanism 3. A fixed head 203 is fixedly installed on one side of the storage cylinder 201, and an extrusion head 204 or a sealing head 205 is threadedly connected to the fixed head 203. The design of the handle 102 and the control button 103 conforms to ergonomics, allowing the operator to comfortably hold it with one hand and accurately control the extrusion action, improving operational convenience and safety. The threaded connection design between the fixed head 203 and the replaceable extrusion head 204 or sealing head 205 realizes the universality and sealing of the outlet, allowing for the replacement of different specifications of the extrusion head 204 as needed, and preventing the ointment from drying or becoming contaminated when not in use. The ointment extrusion device of this utility model features a quick-release mechanism 4 that, through the cooperation of a button 406, an inclined second slide 407, and a spring 412, enables one-handed, quick, and tool-free assembly and disassembly of the material storage mechanism 2, with reliable locking. This greatly improves operational convenience and ointment replacement efficiency. Secondly, the extrusion mechanism 3 employs a transmission method where a motor 302 drives a gear set and a screw 305, providing stable, uniform, and strong linear thrust under the constraint of a guide rod. This effectively overcomes the problems of uneven and laborious manual extrusion, achieving quantitative and controllable extrusion of the ointment. Furthermore, the ergonomically designed handle 102 and control button 103 make operation more comfortable and safer, while the replaceable design of the extrusion head 204 and sealing head 205 enhances the device's versatility and sealing performance. Specifically, first, place the ointment-filled storage mechanism 2 into position. The spring 412 of the quick-release mechanism 4 pushes the mounting rod 409 so that the end clip 410 automatically engages with the locking sleeve 413 at the bottom of the storage cylinder 201 to complete the locking. The operator holds the handle 102 and triggers the control button 103 to start the motor 302. After the motor 302 reduces speed and increases torque through the first gear 303 and the second gear 304, it drives the second gear 304 to rotate. Since the screw 305, which is threaded with the second gear 304, is restricted from rotating by the guide rod, it drives the front extrusion head 306 to move forward in a straight line, pushing the piston 202 to move inside the storage cylinder 201, thereby squeezing the ointment evenly from the extrusion head 204. After use, press the button 406 to unlock and remove the storage mechanism 2 for cleaning or replacement.
