Abstract
Description
Technical Field
[0001] This utility model relates to the field of aerosol bottle processing technology, specifically to a pressure testing device for aerosol bottles. Background Technology
[0002] The spray bottle press test device is a professional device used to test the press function and performance of spray bottles. Its core function is to simulate manual pressing to test the smoothness of pressing, spray effect (mist type, range), sealing (whether there is leakage) and durability (lifespan of repeated pressing). It usually includes a fixing fixture, a press drive mechanism and a data monitoring module. It is mostly used for production quality inspection and R&D testing to ensure the reliability of spray bottle use.
[0003] In the existing technology, the spray bottle press test device cannot collect the spray head water during repeated testing. The test liquid (such as water or simulated medicine) needs to be discharged directly after a single use. Long-term and large-scale testing will cause serious waste of water resources or special test liquids, and increase the cost of purchasing test liquids for enterprises. If the test liquid contains trace additives, direct discharge may also cause slight pollution to the environment. Utility Model Content
[0004] The purpose of this invention is to provide a press-test device for spray bottles, in order to solve the problems mentioned in the background art, such as the inability of existing spray bottle press-test devices to collect nozzle water during repeated testing, the need to directly discharge test liquids (clean water, simulated medicine, etc.) after a single use, the serious waste of water resources or special test liquids and the increase of enterprise procurement costs due to long-term and large-scale testing, and the potential for slight environmental pollution if the test liquid contains trace additives.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a press test device for a spray bottle, including a housing, and a back plate connected to the top rear side of the housing. A recycling port is opened on the top side of the housing near the back plate, and a recycling trough is opened inside the housing, which is connected to the recycling port. A water immersion sensor is connected to the front end of the back plate, and an indicator light is connected to the left end of the back plate. The indicator light is electrically connected to the water immersion sensor. A piston is connected to the rear end of the back plate, and a connecting plate is connected to the output end of the piston. The connecting plate is L-shaped, and a scraper is connected to the rear end of the connecting plate. The scraper is movably connected to the back plate. A button is connected to the front end of the housing, which is electrically connected to the piston. The nozzle sprays water from inside the recycling trough onto the back plate. After the back plate detects the water source, it activates the piston through an external controller. The piston drives the connecting plate to scrape the scraper downwards onto the back plate, scraping the water on the back plate into the recycling port, and then recycling it into the recycling trough through the recycling port.
[0006] Based on the preferred embodiment of this technical solution, an observation window is provided at the left end of the housing, and a lifting frame is connected to the right end of the housing.
[0007] In the preferred embodiment of this technical solution, the lifting frame is internally connected to a lead screw, and a motor is connected to the bottom of the lifting frame, with the output end of the motor connected to the lead screw.
[0008] Based on the preferred embodiment of this technical solution, an adjusting plate is threadedly connected to the outer end of the lead screw, and a pressing plate is connected to the end of the adjusting plate away from the lead screw.
[0009] In the preferred embodiment of this technical solution, a rubber plate is connected to the bottom of the pressing plate, and a placement opening is connected to the top of the housing.
[0010] In the preferred embodiment of this technical solution, the placement port is connected to the recycling tank, a battery is connected to the front end of the housing, the battery is electrically connected to the water immersion sensor, and the battery is electrically connected to the piston and the motor.
[0011] In a preferred embodiment of this technical solution, the front end of the battery is provided with a charging port, which is electrically connected to an external power supply line.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The device connects to the internal recycling tank via the top recycling port of the housing, which can efficiently collect test liquids such as clean water and simulated reagents dripping from the nozzle during testing. This completely avoids the waste caused by direct liquid discharge, creating conditions for subsequent recycling of test liquids, significantly reducing the cost of testing consumables for enterprises, and avoiding the potential environmental pollution caused by direct discharge of test liquids containing additives. With the water immersion sensor at the front of the back panel, the indicator light on the left end, and the scraper, the water sprayed from the nozzle can be recycled into the recycling tank through the scraper, achieving the effect of recycling test liquids.

Detailed Implementation
[0015] 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.
[0016] Please see Figure 1-5 This utility model provides an embodiment of a spray bottle pressing test device, including a housing 1, and a back plate 21 connected to the top rear side of the housing 1. A recycling port 22 is opened on the top side of the housing 1 near the back plate 21. A recycling groove 23 is opened inside the housing 1, and the recycling groove 23 is connected to the recycling port 22. A water immersion sensor 24 is connected to the front end of the back plate 21, and an indicator light 25 is connected to the left end of the back plate 21. The indicator light 25 is electrically connected to the water immersion sensor 24. A piston 26 is connected to the rear end of the back plate 21. A connecting plate 27 is connected to the output end of the piston 26. The connecting plate 27 is L-shaped, and a scraper 28 is connected to the rear end of the connecting plate 27. The scraper 28 is movably connected to the back plate 21. A button 29 is connected to the front end of the housing 1, and the button 29 is connected to the piston. The 26-way electrical connection connects the test liquid (clean water, simulated reagent, etc.) dripping from the nozzle during testing via the recycling port 22 at the top of the housing 1, which is connected to the internal recycling tank 23. This allows for direct collection of the test liquid. This avoids waste caused by direct discharge of the liquid. The design is equipped with a water immersion sensor 24 at the front of the back plate 21 and an indicator light 25 at the left end. When the water immersion sensor 24 detects moisture, the indicator light 25 will light up. At the same time, pressing the button 29 at the front of the housing 1 will activate the piston 26 at the rear of the back plate 21. The piston 26 drives the L-shaped connecting plate 27 and the scraper 28 to move along the back plate 21, which can quickly clean the water on the back plate 21 and recycle it into the recycling tank 23. This design achieves centralized recycling of the test liquid, effectively solving the problems of test liquid waste, high cost, and environmental pollution in traditional devices, and also reduces the difficulty of manual maintenance.
[0017] Please see Figure 2-5 A further solution based on this embodiment is as follows: an observation window 31 is provided at the left end of the housing 1, and a lifting frame 32 is connected to the right end of the housing 1. The observation window 31 allows for a direct view of the liquid level of the test liquid in the recovery tank 23 and whether there is any accumulation of impurities. The internal situation can be understood without disassembling the housing 1, reducing maintenance operation steps. The lifting frame 32 provides a stable mounting carrier for the subsequent height adjustment of the pressing structure, avoiding the shaking of the adjustment parts from affecting the pressing test accuracy, and laying a structural foundation for adapting to different specifications of spray bottles.
[0018] Please see Figure 1-5A further solution based on this embodiment is as follows: a lead screw 33 is rotatably connected inside the lifting frame 32, and a motor 34 is connected to the bottom of the lifting frame 32. The output end of the motor 34 is connected to the lead screw 33. The motor 34 can precisely drive the lead screw 33 to rotate. Compared with manual adjustment, the rotation amplitude of the lead screw 33 can be controlled by the speed of the motor 34, providing a stable and controllable power source for pressing height adjustment, avoiding adjustment deviation caused by uneven force during manual adjustment, and improving the accuracy of pressing position control.
[0019] Please see Figure 1-5 A further solution based on this embodiment is as follows: an adjusting plate 35 is threadedly connected to the outer end of the lead screw 33, and a pressing plate 36 is connected to the end of the adjusting plate 35 away from the lead screw 33. The adjusting plate 35 is driven to move up and down through the threaded transmission, thereby driving the pressing plate 36 to adjust its height synchronously. This can be flexibly adapted to the height of the spray bottle pressing head, ensuring that the pressing plate 36 can accurately align with the pressing parts of different specifications of spray bottles, avoiding inaccurate test data due to pressing position deviation, and improving the adaptability of the device to different spray bottles.
[0020] Please see Figure 1-5 A further solution based on this embodiment is as follows: a rubber plate 37 is connected to the bottom of the button plate 36, and a placement port 38 is connected to the top of the housing 1. The rubber plate 37 is soft and can prevent damage to the pressing head caused by hard contact between the button plate 36 and the spray bottle pressing head. At the same time, it increases the friction during pressing and prevents the button plate 36 from slipping. The placement port 38 can position the spray bottle to ensure that the pressing head and the button plate 36 are accurately aligned after the spray bottle is placed. It also works with the recycling tank 23 to achieve directional collection of test liquid and reduce liquid leakage and waste.
[0021] Please see Figure 1-5 A further solution based on this embodiment is as follows: the placement port 38 is connected to the recycling tank 23, the front end of the housing 1 is connected to the battery 39, the battery 39 is electrically connected to the water immersion sensor 24, the battery 39 is electrofused to the piston 26 and the motor 34, and the placement port 38 is connected to the recycling tank 23, which can guide the liquid dripping during the press test of the spray bottle to flow directly into the recycling tank 23, further improving the test liquid recycling path and reducing liquid residue; the battery 39 provides independent power supply for the water immersion sensor 24, piston 26 and motor 34, eliminating the device's dependence on external power cords, improving the flexibility of the device's use (such as being able to conduct temporary tests in scenarios without external power supply), and ensuring the stable operation of each electrical component.
[0022] Please see Figure 1-5A further solution based on this embodiment is as follows: a charging port 310 is provided at the front end of the battery 39. The charging port 310 is electrically connected to an external power cord. The charging port 310 can be conveniently connected to an external power cord to replenish the battery 39, preventing the device from stopping after the battery 39 is depleted and extending the continuous working time of the device. The device can be recharged without replacing the battery 39, reducing the operation cost and time cost of replacing the battery 39 and improving the convenience and continuity of the device.
[0023] Working Principle: First, a basic power supply is ensured. The battery 39 at the front of the housing 1 provides independent power support for the water immersion sensor 24, piston 26, and motor 34, freeing them from the constraints of an external power cord and adapting to temporary testing scenarios without an external power source. When the battery 39 is low on power, it can be replenished by connecting an external power cord through the front charging port 310, ensuring continuous and stable operation of the device. Next, the pressing head is placed into the placement opening 38 at the top of the housing 1. The placement opening 38 quickly positions the pressing head, ensuring that the pressing head is aligned with the pressing plate 36. The motor 34 is then started, and the output end of the motor 34 drives the lead screw 33 inside the lifting frame 32 to rotate. The lead screw 33 drives the adjusting plate 35 to move up and down through the threaded transmission. The adjusting plate 35 simultaneously drives the pressing plate 36 connected to one end to adjust its height until the rubber plate 37 at the bottom of the pressing plate 36 is in contact with the pressing head. This avoids hard contact that could damage the pressing head and increases friction to prevent slippage during pressing, preparing for precise pressing tests. Then, the pressing plate 36 is pressed. During the press-head test, some of the test liquid (clean water, simulated medicine, etc.) dripping from the nozzle flows directly into the recycling tank 23 connected to it through the placement port 38, while the other part drips onto the back plate 21. At the same time, the recycling port 22 on the top of the housing 1 also guides the scattered test liquid into the recycling tank 23, realizing centralized collection of test liquid and avoiding waste and pollution. The water immersion sensor 24 at the front end of the back plate 21 monitors the moisture status of the back plate 21 in real time. If water accumulation is detected, the indicator light 25 on the left end of the back plate 21 is immediately triggered to remind the staff to start the button 29. The button 29 activates the piston 26 at the rear end of the back plate 21. The piston 26 drives the L-shaped connecting plate 27 and the scraper 28 to move along the back plate 21, quickly cleaning the residual liquid on the back plate 21 and guiding the liquid into the recycling tank 23. The staff can also directly view the test liquid level and impurities in the recycling tank 23 through the observation window 31 on the left end of the housing 1. The internal status can be grasped without disassembling the housing 1, reducing the difficulty of maintenance.
[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
