Description

Technical Field

[0001] The present invention relates to the technical field of pumping control for cleaning supplies, particularly to an automatic liquid-discharging multi-functional soap dispenser and a pump body control method applied to the automatic liquid-discharging multi-functional soap dispenser. Background Art

[0002] In daily life, as a common sanitary device, a soap dispenser is widely used in public places such as homes, hotels, hospitals, schools, etc. to provide hand sanitizer or soap liquid for people to conveniently clean their hands. With the improvement of people's living standards and the emphasis on sanitary conditions, the performance and requirements for soap dispensers are also continuously increasing.

[0003] However, the mainstream soap liquid devices in the prior art generally have the following significant defects: 1. Traditional soap dispensers usually only have a single liquid storage cavity and cannot be compatible with the combined application of liquid soap and foam soap at the same time. For example, a single liquid soap dispenser is difficult to meet the user's demand for foam cleaning, while a dedicated foam soap dispenser cannot directly adapt to the use scenario of ordinary liquid soap, resulting in the user having to purchase multiple devices to cover the demand, causing space occupation and cost increase.

[0004] 2. Liquid soap is prone to precipitation or crystallization at low temperatures, such as the precipitation of calcium and magnesium salts formed when the water hardness is high, which affects the smoothness of liquid discharge; while the foaming stability of foam soap is sensitive to the storage temperature. In a high-temperature environment, the mechanical strength of the foam structure decreases, resulting in easy rupture and shortened residence time.

[0005] 3. After long-term use, the soap residue forms a biofilm or inorganic water scale at the bottom of the liquid storage cavity, in the pump body and in the pipeline. In particular, the deposition of metal ions in liquid soap may block the liquid discharge channel and breed bacteria. The traditional solution depends passively on the user to manually disassemble and clean regularly, but the complex internal structure leads to low maintenance efficiency, and repeated disassembly and assembly easily cause component wear.

[0006] 4. Most commercially available soap dispensers use a fixed-quantity mechanical pump and cannot flexibly adjust the liquid discharge amount according to actual needs. Although some electronic devices introduce infrared induction control, the functional limitations of a single sensor make it impossible to independently adjust the liquid discharge parameters for different types of soap, such as liquid soap and foam soap, and lack an adaptive compensation mechanism for abnormal working conditions, such as dirt blockage. Summary of the Invention

[0007] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides an automatic liquid-discharging multi-functional soap dispenser, which integrates multiple functions, can provide liquid soap and foam soap simultaneously, accurately control the liquid-discharging amount, and also integrates the function of improving the solubility of the soap solution after heating and then automatically removing scale, effectively preventing dirt accumulation and soap solution deterioration, thereby improving the convenience of use, extending the service life of the device, meeting modern hygiene requirements, and having significant market application value.

[0009] According to the automatic liquid-discharging multi-functional soap dispenser of the present invention, it includes: A base, which is provided with an independent first liquid storage cavity for storing liquid soap, a second liquid storage cavity for storing foam soap, a first liquid-discharging hole for outputting the liquid soap, a second liquid-discharging hole for outputting the foam soap, a pumping device for respectively pumping and outputting the liquid soap and the foam soap, as well as a first sensor and a second sensor; The first sensor is used to detect an object approaching the first liquid-discharging hole and control the output of a first preset amount of the liquid soap, and the second sensor is used to detect an object approaching the second liquid-discharging hole and control the output of a second preset amount of the foam soap; A scale-removing liquid-discharging assembly, which includes 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; A control device, which is arranged on the base. The control device includes a PCB control board and control keys. The PCB control board integrally controls the pumping device, the first sensor, the second sensor, and the scale-removing liquid-discharging assembly. When the detection value of the dirt detection sensor is greater than a preset value, after operating the heating device for a preset time, the pumping device is operated to output a third preset amount of the liquid soap, and the third preset amount is greater than the first preset amount. The control keys are used to control the first preset amount and / or the second preset amount and / or the third preset amount.

[0010] The automatic liquid-discharging multifunctional soap dispenser according to the present invention has at least the following beneficial effects: liquid soap and foam soap are stored respectively by independently arranged first liquid storage chamber and second liquid storage chamber, and are equipped with corresponding pumping devices, first sensors and second sensors, so as to realize multifunctional integration and meet the use requirements of users in different occasions and with different preferences; at the same time, through the setting of dirt detection sensor and heating device, the dirt on the bottom is automatically detected, and the solubility of scale can be increased after heating, so that at least part of the scale is dissolved, especially for the precipitation of calcium and magnesium salts caused by water hardness, so that the precipitated solid dirt is caused to be redissolved in the liquid soap, and then the liquid soap is forcibly discharged with a third preset amount greater than the conventional liquid discharge amount, so as to form a high-speed fluid to flush the first liquid storage chamber and the inner wall of the pipeline, effectively remove the residual scale, and realize The current automated deep-level automatic liquid discharge and descaling cleaning can effectively keep the liquid soap clean and effective after long-term use or long-term standing, breaking through the cumbersome process of traditional manual disassembly and cleaning. The intelligent "hot melt + physical flushing" cleaning logic can significantly extend the life of the equipment while ensuring the purity of the soap liquid ingredients and the stability of the liquid discharge; in addition, the control device accurately controls the amount of normal liquid discharge and descaling liquid discharge, avoiding waste, ensuring effective dirt removal, and improving the efficiency of use; the overall operation is convenient, the adjustment is convenient, and the degree of automation is high, which not only improves the user's cleaning experience, but also extends the service life of the equipment through intelligent control and management, and reduces maintenance costs.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0029] For this reason, as Figures 1 to 7As shown in the figure, the present invention provides an automatic liquid-discharging multi-functional soap dispenser, which includes a base 100, a pumping device, a first sensor 110, a second sensor 120, a descaling and liquid-discharging assembly 300, and a control device. Among them, the top of the base 100 is provided with an independent first liquid storage chamber 101 for storing liquid soap and a second liquid storage chamber 102 for storing foam soap. And the bottom of the base 100 is provided with a first liquid outlet hole 103 for outputting liquid soap and a second liquid outlet hole 104 for outputting foam soap. Correspondingly, a pumping device for respectively pumping and outputting liquid soap and foam soap is arranged inside the base 100. 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 liquid storage chamber 101 to the first liquid outlet hole 103, and the second soap pump 220 can pump the foam soap in the second liquid storage chamber 102 to the second liquid outlet hole 104. And the base 100 is equipped with an air inlet pipe, and the air inlet pipe is provided with an air inlet hole 2201 to enter the air inlet end of the second soap pump 220. Then, air and foam soap are mixed in the second soap pump 220, and foam is ejected from the second liquid outlet hole 104. Specifically, the first sensor 110 is used to detect an object approaching the first liquid outlet hole 103 and control the output of a first preset amount of liquid soap, and the second sensor 120 is used to detect an object approaching the second liquid outlet hole 104 and control the output of a second preset amount of foam soap. Further, the descaling and liquid-discharging 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 liquid soap. In addition, the control device includes a PCB control board 410 and control keys 420. The PCB control board 410 integrally controls the pumping device, the first sensor 110, the second sensor 120, and the descaling and liquid-discharging assembly 300. In some applications, when the detection value of the dirt detection sensor is greater than a preset value, after operating the heating device 320 for a preset time, the pumping device is operated to output a third preset amount of liquid soap, and the third preset amount 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 conventional liquid discharge amount of the soap can be selected as 4.5 ml, 3.0 ml, and 1.5 ml according to the composition of the soap. For example, both the first preset amount and the second preset amount are 3.0 ml, and the third preset amount is 10.0 ml. It should be noted that by independently setting the first liquid storage chamber 101 and the second liquid storage chamber 102 to store liquid soap and foam soap respectively, and equipping corresponding pumping devices, the first sensor 110 and the second sensor 120, multi-functional integration is achieved, which can meet the usage requirements of users in different occasions and with different preferences.Meanwhile, through the settings of the dirt detection sensor 310 and the heating device 320, the dirt at the bottom is automatically detected. After heating, the solubility of water scale can be increased, enabling at least part of the water scale to dissolve. Especially for the calcium and magnesium salt precipitation caused by water hardness, it can prompt the precipitated solid dirt to redissolve in the liquid soap solution, and then force the liquid soap solution to be discharged at a third preset volume greater than the conventional liquid discharge volume, forming a high-speed fluid to flush the inner walls of the first liquid storage cavity 101 and the pipeline, effectively removing the residual scale, realizing automatic liquid discharge and scale removal cleaning with high automation depth, and being able to effectively maintain the cleanliness and effectiveness of the liquid soap solution after long-term use or long-term standing. It breaks through the cumbersome process of traditional manual disassembly and cleaning. The intelligent "thermal dissolution + physical flushing and discharging" cleaning logic can significantly extend the service life of the equipment, while ensuring the purity of the soap solution components and the stability of liquid discharge. In addition, through the precise control of the control device for the normal liquid discharge and the scale removal liquid discharge volume, waste is avoided, effective dirt removal is ensured, and the use efficiency is improved; the overall operation is convenient, the adjustment is easy, and the degree of automation is high. It not only improves the user's cleaning experience, but also extends the service life of the equipment through intelligent control and management, reduces the maintenance cost, and is applicable to various places such as families, hotels, hospitals, schools, etc., with significant market application value and broad application prospects. In some settings, when the detection value of the dirt detection sensor 310 is greater than the preset value, i.e., the threshold value, 10 ml of the liquid soap solution is pumped out after heating for 15 seconds. In some settings, the dynamic weight algorithm is adopted. When the detection value of the dirt detection sensor 310 continuously exceeds the threshold value, for example, after 5 cycles, the third preset volume is automatically increased from the initial value, such as 10 ml, to 1.5 times of it, i.e., 15 ml, and the heating time is extended from 15 seconds to 20 seconds to enhance the processing ability for stubborn dirt. In addition, the cleaning cycle data can be recorded simultaneously, and the next maintenance time can be predicted through machine learning, controlled within an error of ±2 days, to achieve preventive maintenance. Tests show that this method enables the equipment to operate continuously for 6 months without manual cleaning, and the efficiency is increased by 70% compared with the traditional method.

[0030] In some embodiments, a temperature detection sensor can be set to detect the liquid soap solution in the first liquid storage cavity 101. The temperature value detected by the temperature detection sensor is added to the feasibility condition judgment of the operation of the heating device 320 in the control algorithm to avoid damage to the equipment caused by steam generated when the liquid soap solution overheats. It should be noted that in some special cases, manual cleaning is still required. For example, when the equipment is idle for a long time and the dirt cannot be discharged even with a large discharge volume after heating. In this regard, after each liquid replenishment, the dirt detection sensor 310 will run once. If it is judged that the detection value of the dirt detection sensor 310 continuously exceeds the threshold value, correspondingly, the heating device 320 will keep heating, and the user can observe that the liquid soap solution is continuously discharged, visually obtaining the treatment method that requires manual cleaning and maintenance. Or, a sound generator is provided on the base 100. When in this state, the sound generator reminds the user to clean in time by making a sound.

[0031] In some other applications, when the detection value of dirt detection sensing is greater than a preset value, the pumping device is operated to output a fourth preset amount of foamed soap solution, and the fourth preset amount is greater than the second preset amount. Without separately detecting the dirt condition of the foamed soap solution, the follow-up control principle is adopted. When it is detected that liquid soap solution should be discharged, it is defaulted that the foamed soap solution should also be descaled, improving the self-cleaning ability and service life of the entire device. In some applications, the second preset amount is set as the conventional liquid output amount, and the fourth preset amount is set as 2-3 times the conventional liquid output amount. Under high-pressure pumping, a turbulent flow with a Reynolds number > 5000 is formed, which can not only remove the dirt at the bottom of the second liquid storage cavity 102, but also generate a shear peeling effect on the colloidal dirt at the corners of the relevant pipelines, such as the mixture of fatty acid salts and skin cutin, reducing the manual dry cleaning frequency by 60%. In some applications, the conventional liquid output amount of the soap solution can be selected as 4.5 ml, 3.0 ml, and 1.5 ml according to the composition of the soap solution.

[0032] In still some other embodiments of the present invention, such as Figure 6 As shown, the heating device 320 includes a first thermoelectric cooler 321. A sandwich layer 105 is provided between the first liquid storage cavity 101 and the second liquid storage cavity 102. The first thermoelectric cooler 321 is located in the sandwich layer 105. The heating side of the first thermoelectric cooler 321 faces the first liquid storage cavity 101, and the cooling side of the first thermoelectric cooler 321 faces the second liquid storage cavity 102. In this regard, by using the first thermoelectric cooler 321, heating can be achieved while cooling is carried out, effectively utilizing energy. And through the design of the sandwich layer 105, the temperatures of the liquid soap solution and the foamed soap solution are respectively regulated, improving the efficiency and accuracy of temperature control, extending the storage period of the soap solution, reducing the risk of deterioration, and reducing the overall energy consumption. Moreover, the recycling of heat is realized, improving the operation efficiency and stability of the device. It is easy to understand that the heating side of the first thermoelectric cooler 321 heats the liquid soap solution to dissolve water scale (such as calcium and magnesium salt deposits), and the cooling side provides low-temperature protection for the foamed soap solution cavity, avoiding the temperature crosstalk problem caused by energy conduction in the traditional single-cavity heating mode. For example, the liquid soap solution cavity can be heated to the optimal solubility temperature of water scale, 50°C, within 5 minutes, while the foamed soap solution cavity is cooled to below 20°C, which can effectively inhibit the attenuation of surfactant activity.

[0033] In some other embodiments of the present invention, such as Figure 3 and Figure 4As shown, the heating device 320 includes a heating wire 322, which is arranged on the outer side of the first liquid storage cavity 101 facing away from the second liquid storage cavity 102. It has a simple structure, is easy to install and maintain, can effectively heat the liquid soap, prevent precipitation or crystallization due to low temperature, and ensure the normal use and cleaning effect of the liquid soap. Moreover, the heating wire 322 arranged on the outer side of the first liquid storage cavity 101 transfers heat to the liquid soap by heating the cavity wall of the first liquid storage cavity 101, avoiding the decomposition of the liquid soap caused by local overheating of the liquid soap due to direct heating contact with the liquid soap, such as the oxidation of glycerol. Thus, the stability of the liquid soap components is ensured. For example, the cavity wall of the first liquid storage cavity 101 is an aluminum alloy substrate. Experiments show that taking 500 ml of liquid soap as an example, heat is conducted through the aluminum alloy substrate with a thermal conductivity ≥ 200 W / m·K to ensure uniform heating of the liquid soap. The maximum temperature rise rate of the liquid soap can reach 8°C / minute, and the power can be dynamically adjusted by the PID algorithm during the heating process. In addition, the heating wire 322 arranged on the outer side of the first liquid storage cavity 101 facing away from the second liquid storage cavity 102 can avoid affecting the foaming soap liquid in the second liquid storage cavity 102 and reduce the risk of foam rupture caused by the accelerated molecular thermal motion of the foaming soap liquid due to the increase in its temperature. Further, a heat insulation layer 106 is provided between the first liquid storage cavity 101 and the second liquid storage cavity 102, which can reduce heat transfer, improve energy utilization efficiency, ensure the stability of the temperatures of the two kinds of soap liquids respectively, and avoid mutual interference. Optionally, the heat insulation layer 106 is a nano-aerogel heat insulation layer 106 with a thickness ≥ 5 mm, which can reduce the heat conduction coefficient between the first liquid storage cavity 101 and the second liquid storage cavity 102 to below 0.02 W / m·K. Even if the liquid soap cavity remains at a high temperature such as 55°C in the continuous descaling mode, the temperature of the foaming soap liquid cavity is still stable between 15°C - 20°C, avoiding the attenuation of the foam volume caused by high temperature. For the traditional structure, the attenuation rate > 30%, and in this solution, it is controlled within 8%. In some other embodiments of the present invention, the machine base 100 is provided with a first air outlet 107, and the first air outlet 107 is located on the outer side of the first liquid storage cavity 101 facing away from the second liquid storage cavity 102. A first fan 130 and a first partition net 140 are connected inside the machine base 100. The first partition net 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 timely discharge heat, effectively prevent overheating of the first liquid storage cavity 101, ensure the quality of the liquid soap, improve the stability and safety of the equipment operation, and reduce the failure rate caused by overheating.In addition, the soap dispenser can also integrate a blowing function to dry the user's hands after washing. Specifically, when the heating device 320 is not working, the first air outlet 107 blows cold air to dry the user's hands; when the heating device 320 is exactly working, the first air outlet 107 blows hot air to heat and dry the user's hands, which can make full use of the heat generated by the heating device 320 and improve the energy utilization rate. It should be noted that the first thermoelectric cooler 321 and the heating wire 322 can be used separately, and neither affects the air outlet function application of the first air outlet 107. Or, refer to. Figure 5 , the first thermoelectric cooler 321 and the heating wire 322 can be used in combination. At this time, the heat insulation layer 106 of the first liquid storage chamber 101 and the second liquid storage chamber 102 changes to a heat-conducting interlayer 105. Furthermore, the first thermoelectric cooler 321 and the heating wire 322 can heat the relative outer wall of the first liquid storage chamber 101, and can heat the liquid soap more evenly. Optionally, the first blower 130 has an adjustable air volume of 0.5 - 2.0 m³ / min, which can reduce the risk of scalding the user on the outer wall of the machine base 100. Optionally, the first partition net 140 is honeycomb-shaped, with a mesh diameter ≤ 1mm. While maintaining a ventilation efficiency of 60%, it intercepts suspended particles with a particle size > 5μm, reducing the internal dust accumulation of the device by more than 90%, and is suitable for industrial sites with a relatively high dust concentration.

[0034] Refer back to Figure 5 and Figure 6, in some embodiments of the present invention, a second thermoelectric cooler 150 is disposed on the outer side of the second liquid storage chamber 102 facing away from the first liquid storage chamber 101. The cooling side of the second thermoelectric cooler 150 faces the second liquid storage chamber 102 to achieve temperature control of the foam soap liquid, prevent the foam from dissipating too quickly due to excessive temperature, ensure the stability and cleaning effect of the foam soap liquid, optimize the energy consumption performance of the device, and extend the service life of the device. In experimental tests, when the ambient temperature is 35 °C, the temperature of the second liquid storage chamber 102 can still be maintained in the range of 12 °C - 18 °C, the foam half-life is extended to 1.5 times that under conventional conditions, and the coefficient of variation of the foam diameter distribution is optimized from 0.25 to 0.15. Further, in some embodiments of the present invention, the machine base 100 is provided with a second air outlet 108. The second air outlet 108 is located on the outer side of the second liquid storage chamber 102 facing away from the first liquid storage chamber 101. A second fan 160 and a second partition net 170 are disposed in the machine base 100. The second partition net 170 is placed 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 toward the second air outlet 108. On the one hand, it can timely dissipate the heat generated by the heating side of the second thermoelectric cooler 150. On the other hand, it integrates the air outlet function and can dry the user's hands after washing hands. Specifically, when the second thermoelectric cooler 150 is not working, the second air outlet 108 blows cold air to dry the user's hands; when the second thermoelectric cooler 150 is just working, the second air outlet 108 blows hot air to heat and dry the user's hands, which can make full use of the heat generated by the second thermoelectric cooler 150 and improve the energy utilization rate.

[0035] Compared with the operations of conventional open-top liquid replenishment and frequent open-top cleaning, it is necessary to remove the top cover, which may lead to difficulties in manual operation if the installation height is too high, and the problem that the top cover cannot fit the mirror cabinet, etc. As a result, it invisibly occupies the unusable space at the top and cannot be tightly combined with other accessories such as the mirror cabinet. Referring again to Figure 1 、 Figure 3 and Figure 5, in some embodiments of the present invention, the side wall of the machine base 100 is provided with a first liquid replenishing hole 109 and a second liquid replenishing hole 1010. The first liquid replenishing hole 109 is communicated with the first liquid storage cavity 101 and is used for replenishing liquid soap, and the second liquid replenishing hole 1010 is communicated with the second liquid storage cavity 102 and is used for replenishing foam soap. Thus, it is convenient to replenish the liquid soap and the foam soap in a timely manner, ensuring the continuous operation of the device, reducing the maintenance cost and time. Moreover, the liquid replenishing process is simple and fast, improving the convenience of use and avoiding the equipment downtime caused by insufficient soap. Optionally, a color marking structure is adopted, such as using blue to identify liquid soap and white to identify foam soap, in combination with a non-contact liquid level sensor, to reduce the misoperation rate of liquid replenishment to less than 1%. Additionally, in some applications, the liquid replenishing flow rate is designed to be 200 - 300 ml / s to avoid the generation of bubbles caused by high-speed filling, such as ensuring that the bubble rate < 0.5%.
