Description

Technical Field

[0001] The present invention relates to the technical field of dust particle counters, and particularly to a probe-separable dust particle counter for the production of light therapy pads. Background Art

[0002] In today's refined production field of light therapy pads, the cleanliness of the production environment is like a cornerstone, playing a decisive role in product quality. As a product that directly acts on the human body and uses specific light for treatment and health care, the stability and reliability of the performance and quality of light therapy pads are crucial. If dust particles are mixed into the production process, they are very likely to adhere to the key components or optical elements of the light therapy pads. This will not only interfere with the transmission and emission of light, resulting in a significant reduction in the light therapy effect, but also may cause surface defects on the product, reducing the durability and safety of the product, and seriously affecting the user experience and health of consumers. Therefore, accurately detecting the number and size of dust particles in the production environment has become the core link to ensure the high-quality production of light therapy pads;

[0003] However, when traditional dust particle counters are applied to the production of light therapy pads, their probes are in a production environment with a high density of dust particles for a long time, constantly contacting dust particles of various particle sizes. Over time, a large number of particulate matters inevitably accumulate on the surface of the probes, making the probes less sensitive to dust particles. In principle, dust particle counters usually detect the number and size of particles through light scattering, laser counting, etc. The particulate matters accumulated on the probes will interfere with the normal propagation and reflection of light, resulting in distorted detection signals, and thus seriously affecting the detection accuracy. More seriously, when the particulate matters accumulate to a certain extent, they may completely block the detection channels of the probes or cause the detection elements to fail, resulting in the inability to carry out the detection work normally. At this time, in order to restore the normal function of the counter, it is necessary to frequently clean and maintain the probes. This process not only requires professional personnel to operate, consuming a lot of time and energy, but also means that the production process is forced to interrupt, increasing the additional time cost. Moreover, during the maintenance period, due to the inability to accurately detect the dust particle situation in the production environment, the product quality control is out of control, and it is very likely to produce unqualified products, bringing huge economic losses to the enterprise;

[0004] In addition, existing dust particle counters generally lack an effective self-cleaning mechanism, which is particularly fatal in scenarios such as the production of phototherapy pads that require long-term and continuous detection. In the production workshop of phototherapy pads, the production line often runs day and night, and the dust particle counter also needs to work around the clock. Under such a high-intensity working state for a long time, the amount of dust adhering to the probe surface increases exponentially. However, existing counters do not have an effective mechanism to clean the probe in a timely and effective manner without stopping the detection work and disturbing the normal production process. As the usage time increases, the detection performance of the probe continues to decline, making it difficult to meet the stringent requirements of high-precision and continuous detection in the production of phototherapy pads. Therefore, it is urgent to develop a dust particle counter that can effectively solve the above problems, which has important practical significance for improving the production quality of phototherapy pads, increasing production efficiency, and enhancing the competitiveness of enterprises. Summary of the Invention

[0005] The purpose of the present invention is to provide a probe-separable dust particle counter for the production of phototherapy pads, so as to solve the problems in the above-mentioned background technology that in the application of traditional dust particle counters in the production of phototherapy pads, the probe is prone to accumulate particulate matter, resulting in dull induction, affected detection accuracy, and even detection failure, and there is a lack of an effective self-cleaning mechanism, and the cleaning and maintenance require interrupting the production process.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A probe-separable dust particle counter for the production of phototherapy pads, including a main body. On one outer surface of the main body, a display screen and a control panel are provided, and air outlets are provided on the outer surfaces at both ends of the main body. An air pump is arranged inside the main body. A switching detection mechanism is fixedly arranged on the upper end surface of the main body. By using the method of alternately using separable probes, the accumulation of particulate matter on the probe is avoided, resulting in detection failure.

[0007] The switching detection mechanism includes: a function seat. A first mounting cover and a second mounting cover are fixedly installed on the upper end of the function seat through bolts. The upper end of the second mounting cover is fixedly connected with an air collection cylinder. A convex block is fixedly arranged on the inner surface of the upper end of the air collection cylinder. A thick filter column is fixedly connected to the upper end of the air collection cylinder. A rotating piston plate is installed inside the thick filter column. A piston rod is fixedly arranged on the lower surface of the piston plate. A pressure cylinder is fixedly arranged inside the lower side surface of the air collection cylinder. The inner surface of the lower end of the air collection cylinder is penetrated by a connecting pipe. One end of the connecting pipe located inside the air collection cylinder penetrates the inner surface of the pressure cylinder, and the other end of the connecting pipe penetrates the lower surface of the second mounting cover. The lower surfaces of the first mounting cover and the second mounting cover are fitted with the upper surface of the function seat.

[0008] The switching detection mechanism further includes: an inhalation tube fixedly arranged on the inner surface of the function seat, with one end of the inhalation tube penetrating through the inner surface of the main body, and the end of the inhalation tube inside the main body being connected to the air pump inlet inside the main body. A light source is fixedly arranged on the inner surface of the function seat, and a central motor is fixedly installed in the middle of the inner bottom surface of the function seat. The upper end of the output shaft of the central motor is fixedly connected to a central disc. An installation rod is fixedly arranged on the outer surface of the central disc, and a sliding sliding rod is installed at one end of the installation rod. One end of the sliding rod is fixedly connected to a function block, and a detection probe is threadedly connected to the temporal part of the side surface of the function block. A plug-in socket is fixedly installed on the side surface of the end of the detection probe facing the inside of the function seat. A sliding sliding seat is installed inside the function seat, and a plug connector is fixedly connected to the end of the sliding seat facing the outside of the function seat. A guiding groove is formed on the upper surface of the sliding seat, and a guiding plate is fixedly arranged on the outer surface of the sliding seat. An electric push rod is fixedly installed on the lower surface of the installation rod;

[0009] A cleaning mechanism is arranged on the side surface of the function seat. By brushing the probe when the detection probe is not working, it is ensured that the probe can remain clean and work properly during long-term operation;

[0010] The cleaning mechanism includes: a diversion groove formed inside the side surface of the function seat, and a relief groove is formed on one side surface of the function seat. An impeller that rotates is installed inside the side surface of the function seat, and one end of the rotating shaft of the impeller is fixedly connected to a cleaning disc.

[0011] Preferably, the coarse filter column is designed to be hollow, and holes are evenly formed on the outer surface of the coarse filter column. The lower end of the coarse filter column is communicated with the upper end of the air collection cylinder. The outer surface of the piston plate is in sliding friction connection with the inner surfaces of the air collection cylinder and the convex block, and a spring is connected between the piston plate and the pressure cylinder. The lower end of the piston plate is in sliding friction connection with the pressure cylinder. The lower end surface of the convex block is higher than the upper end surface of the pressure cylinder.

[0012] Adopting the above technical solution, the hollow design of the coarse filter column and the evenly formed holes on the outer side can initially filter larger impurities in the external air, preventing them from entering the air collection cylinder and affecting the detection. The sliding friction connection of the piston plate with the air collection cylinder, the convex block, and the pressure cylinder, as well as the spring connection with the pressure cylinder, enables the piston plate to move flexibly when the air pressure in the air collection cylinder changes, ensuring that the air in the pressure cylinder can be pressed into the connecting pipe.

[0013] Preferably, the upper end of the inhalation tube is arranged directly opposite to the lower end of the air collection cylinder, and the upper end of the inhalation tube is in contact with the lower surface of the second installation cover. One end of the light source is in contact with the outer surface of the middle section of the inhalation tube, and an opening is arranged on the outer surface of the middle section of the inhalation tube facing the light source. An opening is also arranged on the outer surface of the other side of the inhalation tube facing the light source.

[0014] With the above technical solution, the design that the upper end of the suction pipe is directly opposite to the lower end of the air collecting cylinder and fits the lower surface of the second mounting cover can efficiently suck the air in the air collecting cylinder into the main body, ensuring an adequate detection sample. The light source fits the outer surface of the middle section of the suction pipe and an opening is provided at the corresponding position of the suction pipe, enabling light to fully pass through the air in the suction pipe. When there are dust particles in the air, the light is scattered, providing good conditions for the detection probe to accurately detect the number and size of dust particles according to the light scattering situation, and improving the detection accuracy.

[0015] Preferably, a spring is connected between the mounting rod and the sliding rod. The outer surface of the function block fits the inner surface of the function seat, and the outer surface of the function block facing the suction pipe fits the outer surface of the suction pipe.

[0016] With the above technical solution, the spring connection between the mounting rod and the sliding rod enables the sliding rod to slide flexibly within a certain range, facilitating the adjustment of the position of the detection probe; the outer surface of the function block fits the inner surface of the function seat and the outer surface of the suction pipe, which can ensure the stability of the function block during movement, ensuring that the detection probe is always in a suitable detection position and improving the detection reliability.

[0017] Preferably, a spring is connected between the sliding seat and the function seat. The sliding seat is installed by inserting the plug connector into the socket, and the sliding seat is connected to the main body through a wire.

[0018] With the above technical solution, the spring connection between the sliding seat and the function seat enables it to automatically reset when the electric push rod acts, realizing the quick connection and separation of the plug connector and the socket. By inserting the plug connector into the socket and connecting to the main body through a wire, it can ensure the stable connection between the detection probe and the main body during the switching process, timely transmit the detection data, and ensure the continuity of the detection work.

[0019] Preferably, both the guide groove and the guide plate are arc-shaped, and the guide groove and the guide plate are concentrically arranged, and the guide groove and the guide plate are eccentrically arranged with respect to the central disk.

[0020] With the above technical solution, the arc-shaped and concentric arrangement of the guide groove and the guide plate can provide an accurate guiding effect for the lower end of the electric push rod, enabling the sliding seat to slide along a specific trajectory during movement.

[0021] Preferably, the lower end of the electric push rod facing the sliding seat is located inside the guide groove, and the lower end of the electric push rod fits the inner surface of the guide groove.

[0022] With the above technical solution, the lower end of the electric push rod is located inside the guide groove and fits against the inner surface of the guide groove, enabling it to effectively push the sliding seat during the telescopic process, achieving reliable connection and separation between the plug connector and the socket. By controlling the telescopic movement of the electric push rod, the switching action of the detection probe can be accurately controlled, ensuring that the detection probe can be accurately positioned during switching and guaranteeing the normal progress of the detection work.

[0023] Preferably, the upper end of the diversion groove penetrates through the upper surface of the functional seat, and the upper end of the diversion groove is directly opposite to the lower end of the connecting pipe. The diversion groove penetrates through the inner cavity of the side surface of the functional seat where the impeller is located, and one end of the diversion groove penetrates through the inner surface of the relief groove. One end of the cleaning disc is fixedly provided with bristles, and the bristles on the surface of the cleaning disc protrude from the inner surface of the functional seat.

[0024] With the above technical solution, the upper end of the diversion groove is directly opposite to the lower end of the connecting pipe, which can effectively guide the air discharged from the pressure cylinder into the diversion groove, driving the impeller to rotate. The bristles at one end of the cleaning disc protrude from the inner surface of the functional seat. Driven by the impeller, the surface of the non-working detection probe can be comprehensively brushed, timely removing the attached dust particles, keeping the detection probe clean, maintaining its good detection performance. The relief groove provides space for the air in the diversion groove to be discharged, ensuring that the cleaning disc can rotate smoothly to clean the detection probe, reducing the manual cleaning frequency, and extending the service life of the detection probe.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: The separable dust particle counter for the probe used in the production of the phototherapy mat:

[0026] 1. In the present invention, by alternately using separable detection probes, when one detection probe is working, the other detection probe can be in a non-working state, effectively avoiding the continuous accumulation of particulate matter on the detection probe. This ensures that the working detection probe is always in a relatively clean state, making its induction of dust particles sensitive, greatly reducing the problem of detection signal distortion caused by the accumulation of particulate matter on the surface of the detection probe, and thus significantly improving the stability of the detection accuracy of the dust particle counter, ensuring that the number and size of dust particles can be continuously and accurately detected in the production environment of the phototherapy mat.

[0027] 2. Due to the separable design of the detection probe, there is no need to frequently clean and maintain the working detection probe as in traditional counters. When a certain detection probe needs to be cleaned, the central motor can drive the central disc to rotate, cooperating with structures such as the mounting rod and the sliding rod, and directly switch to another detection probe to continue the detection work. This process not only does not require frequent intervention by professionals but also avoids production interruption caused by maintenance, greatly saving maintenance time and effort, reducing the additional costs brought by production interruption, and significantly improving production efficiency.

[0028] 3. The cleaning mechanism endows the counter with self-cleaning ability. When the detection probe is not working, the cleaning mechanism can automatically brush the detection probe. Specifically, the air flow is guided by the diversion groove to drive the impeller to rotate, and then drive the cleaning disc to clean the surface of the detection probe. This self-cleaning mechanism enables the detection probe to maintain a relatively clean state during long-term operation, reduces the frequency of manual cleaning, further ensures the stability of the detection performance of the detection probe, and also extends the service life of the detection probe and reduces the overall maintenance cost of the equipment.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] Please refer to Figures 1 - 10 , the present invention provides a technical solution: a probe separable dust particle counter for the production of phototherapy pads.

An air pump is arranged inside the main body 1, and a switching detection mechanism is fixedly arranged on the upper end surface of the main body 1. By means of the alternative use of separable probes, the detection failure caused by the accumulation of particulate matter on the probes is avoided;

[0044] The switching detection mechanism includes: a function seat 5, a first mounting cover 6 and a second mounting cover 7 are fixedly installed on the upper end of the function seat 5 by bolts, and a collecting cylinder 8 is fixedly connected to the upper end of the second mounting cover 7. A bump 9 is fixedly arranged on the inner surface of the upper end of the collecting cylinder 8, and a coarse filter column 10 is fixedly connected to the upper end of the collecting cylinder 8. A rotating piston plate 11 is installed inside the coarse filter column 10, and a piston rod 12 is fixedly arranged on the lower surface of the piston plate 11. A pressure cylinder 13 is fixedly arranged inside the lower side surface of the collecting cylinder 8. The inner side surface of the lower end of the collecting cylinder 8 is penetrated by a connecting pipe 14, and one end of the connecting pipe 14 located inside the collecting cylinder 8 penetrates the inner side surface of the pressure cylinder 13, and the other end of the connecting pipe 14 penetrates the lower surface of the second mounting cover 7. The lower surfaces of the first mounting cover 6 and the second mounting cover 7 are attached to the upper surface of the function seat 5;

[0045] The coarse filter column 10 is designed to be hollow, and holes are evenly formed on the outer surface of the coarse filter column 10.

[0046] After the air pump inside the main machine 1 is started by controlling through the display screen 2 and the control panel 3 on the outer surface of the main machine 1, a negative pressure environment will be formed inside the air collecting cylinder 8. The outside air enters the air collecting cylinder 8 through the coarse filter column 10. The coarse filter column 10 is designed to be hollow and holes are evenly formed on the outer surface, which can prevent sundries from entering. The piston plate 11 slides between the air collecting cylinder 8 and the pressure cylinder 13.

When the air pressure inside the air collecting cylinder 8 changes, at this time, the piston plate 11 slides downward under the action of pressure until the upper surface of the piston plate 11 is lower than the lower end surface of the convex block 9. At this time, the outside air can be sucked downward from the air collecting cylinder 8 into the main machine 1, and the piston plate 11 drives the piston rod 12 to slide downward, so that the air inside the pressure cylinder 13 is discharged downward through the connecting pipe 14. When the components need to be replaced, the bolts connecting the first mounting cover 6 and the second mounting cover 7 to the functional seat 5 are removed, and the first mounting cover 6 and the second mounting cover 7 can be removed.
