Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pump control of cleaning supplies, in particular to an automatic liquid dispensing multifunctional soap dispenser and a pump body control method applied to the automatic liquid dispensing multifunctional soap dispenser. BACKGROUND

[0002] In daily life, as a common sanitary equipment, soap dispensers are widely used in public places such as families, hotels, hospitals and schools to provide hand sanitizer or soap liquid to facilitate people to clean their hands. With the improvement of people's living standards and the emphasis on sanitary conditions, the performance and requirements of soap dispensers are also constantly improving.

[0003] However, the mainstream soap liquid equipment in the prior art has the following significant defects:

[0004] 1. The traditional soap dispenser is usually configured with a single liquid storage cavity, which cannot simultaneously support the combined application of liquid soap and foam soap. For example, a single liquid soap dispenser cannot meet the user's demand for foam cleaning, and a special foam soap dispenser cannot directly adapt to the use scenario of ordinary liquid soap, resulting in the need for users to purchase multiple devices to cover their needs, causing space occupation and cost increase.

[0005] 2. Liquid soap is prone to precipitation or crystallization at low temperatures, such as calcium and magnesium precipitates formed when water hardness is high, affecting the smoothness of the liquid flow; the foaming stability of foam soap is sensitive to storage temperature, and the mechanical strength of the foam structure decreases in a high-temperature environment, resulting in easy breakage and shortened residence time.

[0006] 3. After long-term use, biological membranes or inorganic scale formed by soap residues at the bottom of the liquid storage cavity, pump body and pipeline, especially the deposition of metal ions in liquid soap, may block the liquid outlet channel and breed bacteria. The traditional solution passively relies on users to manually disassemble and clean regularly, but the complex internal structure results in low maintenance efficiency, and repeated disassembly and assembly can easily cause component wear.

[0007] 4. Commercial soap dispensers mostly use fixed and quantitative mechanical pumps, which cannot flexibly adjust the liquid output according to actual needs. Although some electronic devices introduce infrared sensing control, the functional limitations of a single sensor make it impossible to independently adjust the liquid output parameters for different types of soap, such as liquid soap and foam soap, and lack a self-adaptive compensation mechanism for abnormal working conditions such as dirt blockage. SUMMARY

[0008] The present application aims to at least solve one of the technical problems existing in the prior art. To this end, the present application proposes an automatic liquid outlet multifunctional soap dispenser, which integrates multiple functions in one, can provide liquid soap and foam soap at the same time, accurately control the liquid outlet amount, and also integrates heating to improve the solubility of the soap after automatic descaling, effectively prevent dirt accumulation and soap deterioration, thereby improving the use convenience, prolonging the equipment life, meeting the modern hygiene needs, and having significant market application value.

[0009] The present application also proposes a pump body control method applied to the above-mentioned automatic liquid outlet multifunctional soap dispenser.

[0010] The automatic liquid outlet multifunctional soap dispenser according to the present application comprises:

[0011] A machine base is provided with a first liquid storage cavity for storing liquid soap and a second liquid storage cavity for storing foam soap, a first liquid outlet hole for outputting the liquid soap, a second liquid outlet hole for outputting the foam soap, a pumping device for pumping and outputting the liquid soap and the foam soap respectively, and a first sensor and a second sensor;

[0012] The first sensor is used for detecting the object close to the first liquid outlet hole and controlling the output of the first preset amount of liquid soap, and the second sensor is used for detecting the object close to the second liquid outlet hole and controlling the output of the second preset amount of foam soap;

[0013] A descaling liquid outlet assembly comprises a dirt detection sensor for detecting dirt at the bottom of the first liquid storage cavity and a heating device for heating the liquid soap;

[0014] A control device is arranged in the machine base, and the control device comprises a PCB control board and a control key. The PCB control board integrates control of the pumping device, the first sensor, the second sensor and the descaling liquid outlet assembly. When the detection value of the dirt detection sensor is greater than a preset value, the pumping device is operated to output a third preset amount of liquid soap after the heating device is operated for a preset time. The third preset amount is greater than the first preset amount. The control key is used to control the first preset amount and / or the second preset amount and / or the third preset amount.

[0015] The automatic liquid dispensing multifunctional soap dispenser according to the present invention has at least the following beneficial effects: By independently setting a first and second liquid storage chamber to store liquid soap and foam soap respectively, and equipped with corresponding pumping devices, a first sensor, and a second sensor, it achieves multifunctional integration, meeting the usage needs of users in different situations and with different preferences; simultaneously, through the setting of a dirt detection sensor and a heating device, dirt at the bottom is automatically detected. Heating increases the solubility of scale, dissolving at least part of it, especially for calcium and magnesium salt precipitation caused by water hardness, causing the precipitated solid dirt to redissolve in the liquid soap. Then, a third preset amount of liquid soap is forcibly discharged, greater than the conventional dispensing volume, forming a high-speed fluid that flushes the first liquid storage chamber and the inner wall of the pipe, effectively removing residual scale. This automated, deep-cleaning liquid descaling system effectively maintains the cleanliness and effectiveness of liquid soap solution after prolonged use or standing. It breaks through the cumbersome process of traditional manual disassembly and cleaning. The intelligent "hot dissolution + physical flushing" cleaning logic significantly extends equipment lifespan while ensuring the purity and stability of the soap solution. Furthermore, precise control of the normal and descaling liquid output prevents waste, ensures effective removal of dirt, and improves efficiency. The system is easy to operate, adjust, and highly automated, enhancing the user's cleaning experience. Intelligent control and management extend equipment lifespan and reduce maintenance costs. Suitable for various locations such as homes, hotels, hospitals, and schools, it has significant market value and broad application prospects.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0050] Therefore, such as Figures 1 to 7As shown, the automatic liquid dispensing multifunctional soap dispenser proposed in this invention includes a base 100, a pumping device, a first sensor 110, a second sensor 120, a descaling liquid dispensing assembly 300, and a control device. The top of the base 100 is provided with a first liquid storage chamber 101 for storing liquid soap and a second liquid storage chamber 102 for storing foam soap. The bottom of the base 100 is provided with a first liquid outlet 103 for dispensing liquid soap and a second liquid outlet 104 for dispensing foam soap. Correspondingly, the base 100 is internally equipped with a pumping device for pumping out liquid soap and foam soap respectively. Specifically, the pumping device includes a first soap pump 210 and a second soap pump 220. The first soap pump 210 can pump the liquid soap in the first storage chamber 101 to the first outlet 103, and the second soap pump 220 can pump the foam soap in the second storage chamber 102 to the second outlet 104. In addition, the base 100 is equipped with an air inlet pipe with an air inlet 2201 to enter the air inlet of the second soap pump 220. Then, the air and foam soap are mixed in the second soap pump 220 and foam is generated in the second outlet 104. Specifically, the first sensor 110 is used to detect an object approaching the first liquid outlet 103 and control the output of a first preset amount of liquid soap solution. The second sensor 120 is used to detect an object approaching the second liquid outlet 104 and control the output of a second preset amount of foamed soap solution. Further, the descaling liquid dispensing assembly 300 includes a dirt detection sensor 310 for detecting dirt at the bottom of the first liquid storage chamber 101 and a heating device 320 for heating the liquid soap solution. Additionally, the control device includes a PCB control board 410 and control keys 420. The PCB control board 410 integrates the control of the pumping device, the first sensor 110, the second sensor 120, and the descaling liquid dispensing assembly 300. In some applications, when the detection value of the dirt detection sensor is greater than a preset value, after the heating device 320 has been running for a preset time, the pumping device is activated to output a third preset amount of liquid soap solution, which is greater than the first preset amount. The control keys 420 are used to control the first preset amount and / or the second preset amount and / or the third preset amount. In some applications, the standard dispensing volume of soap solution can be selected as 4.5ml, 3.0ml, and 1.5ml, depending on the soap solution's composition. For example, the first and second preset volumes are both 3.0ml, and the third preset volume is 10.0ml. It should be noted that the independently configured first and second storage chambers 101 and 102 respectively store liquid soap solution and foam soap solution, and are equipped with corresponding pumping devices, a first sensor 110, and a second sensor 120, achieving multi-functional integration and meeting the usage needs of different occasions and users with different preferences.Simultaneously, through the setting of dirt detection sensor 310 and heating device 320, dirt at the bottom is automatically detected. After heating, the solubility of scale can be increased, causing at least part of the scale to dissolve. In particular, for calcium and magnesium salt precipitation caused by water hardness, the precipitated solid dirt is redissolved in liquid soap solution. Then, liquid soap solution is forcibly discharged at a third preset amount greater than the normal discharge volume, forming a high-speed fluid to flush the first liquid storage chamber 101 and the inner wall of the pipe, effectively removing residual scale and realizing automated deep automatic liquid discharge descaling and cleaning. It can effectively maintain the cleanliness and effectiveness of liquid soap solution after long-term use or long-term standing, breaking through the cumbersome process of traditional manual disassembly and cleaning. The intelligent "hot dissolution + physical flushing" cleaning logic can significantly extend the equipment life, while ensuring the purity of soap solution components and the stability of liquid discharge. Furthermore, the precise control of the normal liquid output and descaling liquid output by the control device avoids waste, ensures effective removal of dirt, and improves the efficiency of use. The overall operation is convenient, easy to adjust, and highly automated, which not only enhances the user's cleaning experience but also extends the equipment's lifespan and reduces maintenance costs through intelligent control and management. It is suitable for various places such as homes, hotels, hospitals, and schools, and has significant market application value and broad application prospects. In some settings, when the detection value of the dirt detection sensor 310 exceeds a preset value (threshold), 10ml of liquid soap solution is pumped out after heating for 15 seconds. In other settings, a dynamic weighting algorithm is used. When the detection value of the dirt detection sensor 310 continuously exceeds the threshold, such as after 5 cycles, the third preset amount is automatically increased from the initial value (e.g., 10ml) to 1.5 times (15ml), and the heating time is extended from 15 seconds to 20 seconds to enhance the ability to handle stubborn dirt. In addition, cleaning cycle data can be recorded simultaneously, and the next maintenance time can be predicted through machine learning, with an error margin of ±2 days, achieving preventative maintenance. Tests show that this method allows the equipment to run continuously for 6 months without manual cleaning, improving efficiency by 70% compared to traditional methods.

[0051] In some embodiments, a temperature sensor can be provided to detect the liquid soap solution in the first storage chamber 101. The temperature value detected by the temperature sensor is added to the feasibility condition judgment of the heating device 320 operation in the control algorithm to avoid the liquid soap solution overheating and generating steam that could damage the equipment. It should be noted that in some special cases, manual cleaning is still required. For example, if the equipment has been idle for a long time, the dirt may not be discharged even after heating. In this case, the dirt detection sensor 310 will run once after each liquid replenishment. If the detection value of the dirt detection sensor 310 is determined to continuously exceed the threshold, the heating device 320 will continue to heat, and the user can observe the continuous discharge of liquid soap solution, visually determining the need for manual cleaning and maintenance. Alternatively, the base 100 can be equipped with a sounder. When in this state, the sounder will remind the user to clean in time.

[0052] In other applications, when the dirt detection sensor reading exceeds a preset value, the pumping device outputs a fourth preset amount of foam soap solution. This fourth preset amount is greater than the second preset amount, eliminating the need for separate detection of dirt in the foam soap solution. Employing a follow-up control principle, when it's detected that liquid soap solution should be discharged, the foam soap solution is automatically descaled, improving the overall self-cleaning capability and lifespan of the equipment. In some applications, the second preset amount is set to the normal output volume, and the fourth preset amount is set to 2-3 times the normal output volume. Under high-pressure pumping, turbulent flow with a Reynolds number > 5000 is created. This not only removes dirt from the bottom of the second storage chamber 102 but also shears and peels away gelatinous dirt, such as a mixture of fatty acid salts and skin keratin, at pipe bends, reducing the frequency of manual dry cleaning by 60%. In some applications, the normal output volume of the soap solution can be selected according to its composition, such as 4.5ml, 3.0ml, and 1.5ml.

[0053] In some other embodiments of the invention, such as Figure 6 As shown, the heating device 320 includes a first thermoelectric cooler 321. A jacket 105 is provided between the first liquid storage chamber 101 and the second liquid storage chamber 102. The first thermoelectric cooler 321 is located within the jacket 105, with its heating side facing the first liquid storage chamber 101 and its cooling side facing the second liquid storage chamber 102. By employing the first thermoelectric cooler 321, cooling can be achieved simultaneously with heating, effectively utilizing energy. Furthermore, the jacket 105 design allows for separate temperature control of the liquid soap solution and the foamed soap solution, improving the efficiency and accuracy of temperature control, extending the shelf life of the soap solution, reducing the risk of spoilage, lowering overall energy consumption, and enabling heat recycling, thus improving the operating efficiency and stability of the equipment. It is easy to understand that the heating side of the first thermoelectric cooler 321 heats the liquid soap solution to dissolve scale (such as calcium and magnesium salt deposits), while the cooling side provides low-temperature protection for the foam soap solution chamber, avoiding the temperature crosstalk problem caused by energy conduction in the traditional single-chamber heating mode. For example, heating the liquid soap solution chamber to the optimal solubility temperature of scale (50°C) within 5 minutes, while simultaneously cooling the foam soap solution chamber to below 20°C, can effectively suppress the decay of surfactant activity.

[0054] In other embodiments of the invention, such as Figure 3 and Figure 4As shown, the heating device 320 includes a heating wire 322, which is disposed on the outer side of the first liquid storage chamber 101 away from the second liquid storage chamber 102. The heating wire 322 has a simple structure, is easy to install and maintain, and can effectively heat the liquid soap solution, preventing precipitation or crystallization due to low temperatures, thus ensuring the normal use and cleaning effect of the liquid soap solution. Furthermore, the heating wire 322, disposed on the outer side of the first liquid storage chamber 101, transfers heat to the liquid soap solution by heating the chamber wall of the first liquid storage chamber 101, avoiding direct heating contact with the liquid soap solution and preventing localized overheating that could lead to decomposition of the liquid soap solution, such as glycerin oxidation. This ensures the stability of the liquid soap solution's components. For example, the chamber wall of the first liquid storage chamber 101 is made of an aluminum alloy substrate. Experiments show that, taking 500ml of liquid soap solution as an example, heat conduction through an aluminum alloy substrate with a thermal conductivity ≥200 W / m·K ensures uniform heating of the liquid soap solution. The liquid soap solution can reach a maximum temperature rise rate of 8°C / minute, and the power can be dynamically adjusted via a PID algorithm during heating. Furthermore, the heating wire 322 is positioned on the outside of the first storage chamber 101, away from the second storage chamber 102, to avoid affecting the foamed soap solution in the second storage chamber 102, reducing the risk of foam breakage due to accelerated molecular thermal motion caused by the increased temperature of the foamed soap solution. Moreover, a heat insulation layer 106 is provided between the first and second storage chambers 101 and 102, which reduces heat transfer, improves energy utilization efficiency, ensures the temperature stability of both soap solutions, and prevents mutual interference. Optionally, the heat insulation layer 106 is a nano-aerogel heat insulation layer with a thickness of ≥5mm, which can reduce the thermal conductivity between the first liquid storage chamber 101 and the second liquid storage chamber 102 to below 0.02 W / m·K. Even if the liquid soap chamber is kept at a high temperature such as 55°C in continuous descaling mode, the temperature of the foam soap chamber remains stable between 15°C and 20°C, avoiding foam volume decay caused by high temperature. For the decay rate of >30% under traditional structure, this solution controls it to within 8%. In some other embodiments of the present invention, the base 100 is provided with a first air outlet 107, which is located on the outside of the first liquid storage chamber 101 away from the second liquid storage chamber 102. A first fan 130 and a first partition 140 are connected inside the base 100. The first partition 140 is placed at the front end of the first air outlet 107, and the first fan 130 is located at the rear end of the first air outlet 107 and can blow air towards the first air outlet 107, which can dissipate heat in time, effectively prevent overheating of the first liquid storage chamber 101, ensure the quality of the liquid soap solution, improve the stability and safety of equipment operation, and reduce the failure rate caused by overheating.In addition, the soap dispenser also integrates an air outlet function to dry the user's hands after washing. Specifically, when the heating device 320 is not working, the first air outlet 107 blows out cold air to dry the user's hands; when the heating device 320 is working, the first air outlet 107 blows out hot air to heat and dry the user's hands, thus making full use of the heat generated by the heating device 320 and improving energy efficiency. It should be noted that the first thermoelectric cooler 321 and the heating wire 322 can be used independently without affecting the air outlet function of the first air outlet 107. Or, see reference. Figure 5 The first thermoelectric cooler 321 and the heating wire 322 can be used together. In this case, the insulation layer 106 of the first liquid storage chamber 101 and the second liquid storage chamber 102 is replaced with a thermally conductive interlayer 105. Consequently, the first thermoelectric cooler 321 and the heating wire 322 can heat the relative outer walls of the first liquid storage chamber 101, resulting in more even heating of the liquid soap solution. Optionally, the first fan 130 has an adjustable airflow of 0.5-2.0 m³ / min, which can reduce the risk of burns to users from the outer wall of the base 100. Optionally, the first mesh 140 is honeycomb-shaped with a mesh diameter ≤1mm. While maintaining 60% ventilation efficiency, it intercepts suspended particles with a diameter >5μm, reducing dust accumulation inside the equipment by more than 90%, making it suitable for industrial environments with high dust concentrations.

[0055] Refer to Figure 5 and Figure 6In some embodiments of the present invention, a second thermoelectric cooler 150 is disposed on the outer side of the second liquid storage chamber 102 away from the first liquid storage chamber 101. The cooling side of the second thermoelectric cooler 150 faces the second liquid storage chamber 102, thereby achieving temperature control of the foam soap solution, preventing the foam from dissipating too quickly due to excessive temperature, ensuring the stability and cleaning effect of the foam soap solution, and optimizing the energy consumption performance of the equipment, thus extending the service life of the equipment. In experimental tests, the temperature of the second liquid storage chamber 102 can still be maintained in the range of 12°-18°C at an ambient temperature of 35°C, extending the foam half-life to 1.5 times that under normal conditions, and optimizing the foam diameter distribution dispersion coefficient from 0.25 to 0.15. Furthermore, in some embodiments of the present invention, the base 100 is provided with a second air outlet 108, which is located on the outer side of the second liquid storage chamber 102 away from the first liquid storage chamber 101. A second fan 160 and a second partition 170 are provided inside the base 100. The second partition 170 is positioned at the front end of the second air outlet 108, and the second fan 160 is located at the rear end of the second air outlet 108 and can blow air towards it. On the one hand, this can promptly dissipate the heat generated by the heating side of the second thermoelectric cooler 150. On the other hand, it integrates an air outlet function, which can dry the user's hands after washing. Specifically, when the second thermoelectric cooler 150 is not working, the second air outlet 108 blows out cold air to dry the user's hands; when the second thermoelectric cooler 150 is working, the second air outlet 108 blows out hot air to heat and dry the user's hands. This fully utilizes the heat generated by the second thermoelectric cooler 150 and improves energy efficiency.

[0056] Compared to the conventional opening and replenishing of liquid and frequent opening and cleaning operations, the need to remove the top cover leads to difficulties in manual operation during installation due to the inability to mount it too high, and also prevents the top cover from fitting snugly against the mirror cabinet. This results in the unintentional occupation of unusable top space and prevents a tight fit with other components such as the mirror cabinet. (See also...) Figure 1 , Figure 3 and Figure 5In some embodiments of the present invention, the side wall of the base 100 is provided with a first replenishment hole 109 and a second replenishment hole 1010. The first replenishment hole 109 is connected to the first liquid storage chamber 101 and is used to replenish liquid soap solution, while the second replenishment hole 1010 is connected to the second liquid storage chamber 102 and is used to replenish foam soap solution. This facilitates timely replenishment of both liquid and foam soap solution, ensuring continuous operation of the equipment, reducing maintenance costs and time, and making the replenishment process simple and quick, improving ease of use and avoiding equipment downtime due to insufficient soap solution. Optionally, a color-coded structure, such as blue for liquid soap solution and white for foam soap solution, combined with a non-contact liquid level sensor, can reduce the replenishment error rate to below 1%. In addition, in some applications, the replenishment flow rate is designed to be 200-300 ml / s to avoid the generation of air bubbles caused by high-speed filling, such as ensuring a bubble rate of <0.5%.
