[0001] The present invention relates to the field of disinfection technology, and in particular to a liquid spraying method, system and device. Background Art

[0002] As people's awareness of environmental hygiene gradually increases, and in order to cope with the spread of various sudden diseases, the use of disinfection to reduce the probability of disease transmission has achieved good results, which is particularly evident in medical institutions.

[0003] However, according to the actual needs of infection control in hospitals, relevant management regulations have put forward the requirement of disinfection for one-person-one-use for frequently used diagnostic and treatment equipment and auxiliary equipment (such as ultrasound probes, stethoscopes, contact thermometers, cupping jars, vacuum jars, oral impressions, models, dentures and technician materials, etc.). For example, taking ultrasound probes as an example, according to the Basic Requirements for Hospital Infection Management in Primary Medical Institutions, ultrasound probes (for ultrasound examinations through the skin, mucous membranes, or through body cavities such as the esophagus, vagina, and rectum) must be disinfected or isolated with a membrane after use by one person.

[0004] Therefore, medical institutions need to disinfect the surface of medical equipment used by each patient. During disinfection, the spraying equipment is required to detect the sprayed object and then spray it. At the same time, it is necessary to ensure that the sprayed disinfectant cannot spread everywhere, and the disinfectant waste liquid flowing from the surface of the sprayed object should be recovered and processed.

[0005] However, the spraying equipment and spraying methods in the prior art generally have problems such as poor spraying effect, low spraying efficiency, high energy consumption, environmental pollution, and complicated operation. The spraying method is also mainly open, and there is no corresponding restriction on the sprayed liquid, resulting in splashing of the sprayed liquid, and the applicability is poor for spraying some liquids that are harmful to the human body.

[0006] The present invention is proposed in view of the above. Summary of the invention

[0015] Furthermore, the method further includes step S3: controlling the driving water pump to spray according to the optimal spraying scheme, and collecting the waste liquid.

[0016] Furthermore, the step S3 also includes: using the information data collected by the gravity sensor to establish a linear relationship with the volume of the waste liquid, and using the linear relationship as reminder data for dumping the waste liquid.

[0037] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] The object of the present invention is to provide a liquid spraying method, system and device, wherein the liquid spraying method comprises the following steps:

[0041] S1. Collect information features of the object to be sprayed, and establish a data model based on the information features;

[0042] S2. Calculate and select the optimal spraying scheme based on the established data model and the initial structural characteristics of the spraying hole 2.

[0043] like Figure 6 As shown, firstly, a data model is established based on the collected information characteristics of the spray object, and the position and shape of the object to be sprayed are calculated. Then, based on the complete match between the position and volume of the object to be sprayed and the position to be covered by the spraying, the optimal spraying scheme is calculated and screened based on the established data model and the initial structural characteristics of the spray hole 2.

[0044] On the basis of the above technical solution, further, the step S1 specifically includes: obtaining the position information and volume information of the object to be sprayed through data analysis of the light collector 3 .

[0045] When disinfecting the object to be sprayed, the placement of the object to be sprayed will cause the light signal to change. The light collector 3 can obtain the relevant position difference. According to the difference changes obtained at different positions, the contour information of the object to be sprayed can be established.

[0046] First, a stable light source environment is created, and light collectors 3 are placed at a certain distance to form a matrix A. Each light collector 3 is a ij express.

[0047] a (ij) 0 means a ij Point initial value, a (ij) 1 means a ij The value after the instrument is placed, △a (ij) Indicates a (ij) The difference.

[0048] △a (ij) =a (ij) 1-a (ij) 0

[0049] △a of the edge of the object to be sprayed (ij) The value will become smaller, and the final area 0 means that no object to be sprayed is found at the inspection position.

[0050] According to △a (ij) Changes in the array determine the location and shape of the objects to be sprayed.

[0051] On the basis of the above technical solution, further preferably, the step S2 specifically includes: formulating multiple spraying positions and spraying amount schemes based on the established data model and the effective spraying range of the spray hole 2, and selecting the optimal spraying scheme.

[0052] like Figure 5 As shown, assuming that the effective spraying range of each spray hole 2 is r=acm, within a fixed area, they are evenly arranged to form a spray matrix A, where the shaded area is a non-sprayable area. According to the position and shape of the object to be sprayed determined in step S1, and then through the known position of the spray hole 2 and the spraying range of a single hole, an artificial intelligence multiple iteration algorithm is used to formulate multiple spray hole 2 position and spray quantity plans, and at the same time, the optimal spraying plan is selected to cover the liquid on the object to be sprayed and control the spraying range.

[0053] On the basis of the above technical solution, more preferably, step S3 is further included: controlling the driving water pump to spray according to the optimal spraying scheme, and collecting the waste liquid.

[0054] After determining the best spraying scheme, the water pump 12 can be controlled to spray the object to be sprayed, and the disinfection completion prompt is given through photoelectric and sound according to the set disinfection completion time. In order to ensure that the disinfectant does not spread or waste, the waste liquid needs to be effectively collected.

[0055] On the basis of the above technical solution, further, step S3 also includes: using the information data collected by the gravity sensor 5 to establish a linear relationship with the volume of the waste liquid, and use it as reminder data for dumping the waste liquid.

[0056] To prevent the sprayed disinfectant from spreading, the disinfectant flowing down the surface of the sprayed object should be recovered and processed. To solve this problem, the present invention uses the information data collected by the gravity sensor 5 to establish a linear relationship with the volume of the waste liquid. When the collected waste liquid exceeds a certain limit, an intelligent algorithm can be used to remind the waste liquid to be dumped.

[0057] Based on the same inventive concept, an embodiment of the present invention also provides a liquid spraying system, which can be used to implement the method described in the above embodiment, as described in the following embodiment. Since the principle of solving the problem by the liquid spraying system is similar to that of a liquid spraying method, the implementation of the spraying system can refer to the implementation of a liquid spraying method, and the repetitions will not be repeated. As used below, the term "unit" or "module" can implement a combination of software and / or hardware of a predetermined function. Although the system described in the following embodiments is preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceived.

[0061] In addition, to further ensure the diffusion of the disinfectant, the liquid spraying system of the present invention also includes a control module for dumping the waste liquid after the spraying is completed, that is, the information data of the gravity sensor 5 is used to establish a linear relationship with the volume of the waste liquid, and the control module completes the dumping of the waste liquid based on the data information comparison of the gravity sensor 5.

[0062] Based on the same inventive concept, the embodiment of the present invention further provides a liquid spraying device, which can be used to implement the method described in the above embodiment, as described in the following embodiment. Since the principle of solving the problem by the liquid spraying device is similar to that of a liquid spraying method, the implementation of the spraying device can refer to the implementation of a liquid spraying method, and the repeated parts will not be repeated.

[0063] like Figure 1-4 As shown, a liquid spraying device of the present invention comprises a spraying cabin 1, wherein the spraying holes 2 and a light collector 3 for collecting information characteristics of the object to be sprayed are arranged in an array inside the spraying cabin 1.

[0064] The liquid spraying device of the present invention is provided with a spraying cabin 1, and the internal array of the spraying cabin 1 is provided with a plurality of spraying holes 2 and a plurality of light collectors 3 for collecting information characteristics of the object to be sprayed, wherein the spraying holes 2 and the light collectors 3 are distributed in a circular array at intervals on the inner surface of the spraying cabin 1, and the plurality of spraying holes 2 arranged at different positions can ensure that the disinfectant fully covers the object to be sprayed, and the plurality of light collectors 3 arranged at different positions can more accurately determine the position, shape and volume of the object to be sprayed.

[0065] On the basis of the above technical solution, further comprising a waste liquid box 4 and a gravity sensor 5;

[0066] The waste liquid box 4 is arranged at the bottom of the spraying cabin 1 and is communicated with the spraying cabin 1;

[0067] The gravity sensor 5 is arranged at the bottom of the waste liquid box 4 , and the collection end of the gravity sensor 5 abuts against the bottom of the waste liquid box 4 .

[0068] In order to prevent the diffusion and waste of disinfectant, the liquid spraying device of the present invention further includes a waste liquid box 4 and a gravity sensor 5, wherein the waste liquid box 4 is arranged at the bottom of the spraying cabin 1 to collect the disinfectant flowing down from the surface of the object to be sprayed. In addition, if the waste liquid in the waste liquid box 4 is not dumped in time, a gravity sensor 5 is arranged at the bottom of the waste liquid box 4, and according to the data information comparison of the gravity sensor 5, a prompt of dumping completion is given through photoelectric and sound.

[0069] The outer surface of the waste liquid box 4 of the liquid spraying device is provided with a liquid level indicating window 9, and the waste liquid in the waste liquid box 4 can also be processed in time by observing the liquid level change of the liquid level indicating window 9.

[0070] To facilitate the operation of the device, a status indicator light 10 and a multi-function key 11 are provided on the upper surface of the device.

[0071] On the basis of the above technical solution, it is further preferred that a loading rack 6 is further included, and the loading rack 6 is slidably arranged outside the spraying cabin 1 .

[0072] The object carrier 6 is slidably arranged outside the spraying cabin 1, and the specific position of the object to be sprayed can be adjusted by moving the object carrier 6 up and down.

[0073] On the basis of the above technical solution, more preferably, the object carrier 6 is provided with a fixing bracket 7 and a limiting protrusion 8 for fixing the object to be sprayed.

[0074] The carrier 6 is provided with a fixing bracket 7 and a limiting protrusion 8 for fixing the object to be sprayed. When in use, the carrier 6 and the fixing bracket 7 can be moved to keep the object to be sprayed and the spraying cabin 1 in a non-contact state.

[0075] The present invention performs data analysis on the sprayed object based on the light collector 3 and the coverage of the spray hole 2, and relies on a reasonable loading algorithm to significantly improve the single disinfectant spray quantity and accuracy, thereby reducing the disinfection cost and improving the operating efficiency. Through data analysis, compared with manual spraying, the intelligent spraying device reduces the single disinfectant usage by 45%, and the waste liquid can be recycled by 95%.

[0076] Taking ultrasound probes as an example, the National Health Commission pointed out in the Basic Requirements for Hospital Infection Management in Primary Medical Institutions that ultrasound probes (ultrasound examinations performed through the skin, mucous membranes, or through the esophagus, vagina, rectum, and other body cavities) must be disinfected or isolated after use by one person. According to the medical institutions' need to disinfect ultrasound probes, the first step is to collect the common sizes of ultrasound probes, design the overall size of the spray cabin 1 and the number and location of the spray holes 2; the second step is to find suitable disinfectant varieties, and set the reminder time for disinfection completion according to the instructions for use of the disinfectant; the third step is to expand the number of smart spraying devices used. Only with more users and usage scenarios can more problems be discovered and the algorithm can be continuously optimized.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
