Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of drinking water machine, especially relates to a double switch direct drinking water machine. BACKGROUND

[0002] With the improvement of people's life quality, the requirement of drinking water safety and convenience is increasing. The traditional drinking water distributor has obvious disadvantages in the use process: when the water is transferred from the sealed bottle to the water storage device, the contact with the surrounding air creates conditions for the growth of bacteria, and the bacteria will reproduce rapidly. After a period of storage, the water body will appear turbidity, which not only affects the appearance, but also causes the taste to be poor, greatly reducing the quality of drinking water.

[0003] To solve the problem of bacterial reproduction, the prior art usually uses hot water to clean the water storage device or drains and dries it regularly. However, these operations have many defects: on the one hand, the operation process is relatively complicated, and the user needs to spend a certain amount of time and energy; on the other hand, frequent cleaning or draining and drying will cause a lot of bottled water to be wasted, increasing the use cost, which is not economically reasonable. INVENTION CONTENTS

[0008] A bottle body is inverted with the neck opening downward and inserted into the container through the inlet of the drinking water machine, and the bottle body is used to contain drinking water.

[0009] A plurality of water outlet pipes are arranged through the drinking water machine body and in communication with the bottom of the container, and the water outlet pipes are respectively a water outlet pipe a, a water outlet pipe b and a water outlet pipe c.

[0010] A distribution faucet is arranged on the water outlet pipe and used to distribute drinking water.

[0011] An ozone injection structure is used to inject air containing disinfecting ozone into the drinking water in the container, and the ozone injection structure comprises a small ozone generator, a blower and a feed pipe for supplying ozone-containing air, and the feed pipe is in communication with the bottom of the container.

[0012] A control unit for controlling the activation and deactivation of the ozone injection structure, the control unit comprising a real-time module and a timer.

[0013] In the above technical solution, further, the feed pipe is provided with a one-way valve to prevent backflow.

[0014] In any of the above technical solutions, further, the small ozone generator comprises a ceramic panel and a high-voltage power supply, the ceramic panel being accommodated in a small chamber formed at an intermediate position of the small ozone generator supplied with air by the air blower.

[0015] In any of the above technical solutions, further, the amount of ozone generated by the ozone generator can be adjusted by a variable resistor connected to the high-voltage power supply.

[0016] In any of the above technical solutions, further, the base end of the water outlet pipe b is provided with a heater.

[0017] In any of the above technical solutions, further, the base end of the water outlet pipe c is provided with an evaporator, the evaporator being connected in series with the compressor and the condenser.

[0018] The beneficial effects of the present application are:

[0020] 2. The real-time module in the control unit can obtain time information, and the timer can set the time. In the period without dispensing drinking water from the water dispenser body (such as at night), the control unit automatically activates the ozone injection structure. After the predetermined time period, the control unit automatically stops the ozone injection structure, which can ensure appropriate ozone injection, ensure the disinfection effect, and fully dissolve the remaining ozone before the next use, without the need to treat the reserve water, avoiding the trouble of cleaning operation and the waste of bottled water.

It should be noted that similar reference numerals and letters in the following drawings denote similar items, and therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0028] Example 1:

[0029] As Figure 1 shown, the embodiment provides a double-switch direct drinking water machine, comprising:

[0030] A water dispenser body 1, in which a container 11 is accommodated, the container 11 being used for receiving and storing drinking water;

[0031] An inlet 12 is opened on the water dispenser body 1, and the inlet 12 is in communication with the container 11;

[0032] A bottle body 13, the bottle neck of the bottle body 13 is inverted downward and inserted into the container 11 through the water dispenser inlet 12, and the bottle body 13 is used for containing drinking water;

[0033] A plurality of water outlet pipes 14 penetrate through the water dispenser body 1 and are in communication with the bottom of the container 11, and the water outlet pipes 14 are respectively a water outlet pipe a 141, a water outlet pipe b 142 and a water outlet pipe c 143;

[0034] A dispensing faucet 15 is arranged on the water outlet pipe 14 and is used for dispensing drinking water;

[0035] An ozone injection structure 2 is used for injecting air containing disinfecting ozone into the drinking water in the container 11; the ozone injection structure 2 comprises a small ozone generator 21, a blower 22 and a feed pipe 23 for supplying ozone-containing air, and the feed pipe 23 is in communication with the bottom of the container 11;

[0036] A control unit 4 is used for controlling the start and stop of the ozone injection structure 2, and the control unit 4 comprises a real-time module 41 and a timer 42.

[0037] In the technical solution, the bottle body 13 containing drinking water is inverted with the bottle neck opening downward, and the container 11 is inserted through the inlet 12 on the water dispenser body 1. The drinking water in the bottle flows into the container 11 for temporary storage by relying on the balance of gravity and pressure in the bottle and the atmospheric pressure in the container 11. The bottom of the container 11 is connected with a plurality of water outlet pipes 14 (water outlet pipe a 141, water outlet pipe b 142 and water outlet pipe c 143), and each water outlet pipe 14 is provided with a distribution faucet 15. When drinking water is needed, the drinking water can flow out of the water outlet pipe 14 by opening the corresponding distribution faucet 15, thereby meeting different use requirements. The small ozone generator 21 in the ozone injection structure 2 generates ozone under the action of the high-voltage power supply 212 through the ceramic panel 211, and the air blower 22 sends air into the ozone generator, part of the air is converted into ozone-containing air, and the ozone-containing air is injected into the drinking water from the bottom of the container 11 through the feed pipe 23. The ozone uses its strong oxidizing property to destroy the bacterial cell structure, disinfects the drinking water, inhibits bacterial reproduction, and prevents the water from becoming turbid and the taste from becoming bad due to bacterial growth. The real-time module 41 in the control unit 4 can obtain time information, and the timer 42 can set the time. In the period without dispensing drinking water from the water dispenser body 1 (such as at night), the control unit 4 automatically starts the ozone injection structure 2. At the same time, the control unit 4 will check whether the water level in the container 11 exceeds the predetermined water level before starting, and if not, it will not start. After the predetermined time period, the control unit 4 automatically stops the ozone injection structure 2. In this way, the appropriate amount of ozone is injected, the disinfection effect is guaranteed, the remaining ozone is fully dissolved before the next use, there is no need to treat the reserved water, and the troublesome cleaning operation and the waste of bottled water are avoided. The double-switch direct drinking water dispenser solves the problems existing in the traditional drinking water dispenser. After the water is transferred from the bottle body 13 to the container 11, bacteria are easy to multiply in large quantities due to contact with air, resulting in turbid water and bad taste. The ozone injection structure 2 and the control unit 4 are arranged in the utility model, the disinfection of the drinking water in the container 11 is realized, the bacterial reproduction is inhibited, the water quality is clear and the taste is good, the troublesome cleaning operation and the waste of bottled water are avoided, and safe, convenient and economical drinking water is provided for users.

[0038] As Figure 1 shown, in the embodiment, the feed pipe 23 is provided with a one-way valve 5 to prevent backflow.

[0039] In the technical solution, ozone is injected into the drinking water in the container 11 through the feed pipe 23 during the operation of the double-switch direct drinking water machine to achieve disinfection. The one-way valve 5 is arranged to prevent the drinking water from flowing back to the feed pipe 23. If backflow occurs, on the one hand, it will dilute the ozone concentration in the feed pipe 23, resulting in insufficient ozone injection into the subsequent water, affecting the disinfection effect, failing to effectively inhibit bacterial reproduction, and thus making the water turbid and taste bad due to bacterial growth. On the other hand, the backflow of water may damage the ozone generation environment of the ozone generator, interfere with its normal operation, and further weaken the disinfection function. The backflow of drinking water may carry impurities, microorganisms, etc. in the container 11 into the feed pipe 23, and even may damage the components of the ozone injection structure 2 such as the air blower 22, affecting the service life and normal operation of the equipment. The one-way valve 5 can prevent this from happening, ensure the cleanliness and safety of the ozone injection structure 2, maintain the stable operation of the equipment, and reduce the maintenance cost and inconvenience caused by equipment failure.

[0040] Working principle: The one-way valve 5 is installed on the feed pipe 23, and its structure design makes it have a specific flow direction. When the ozone-containing air generated by the ozone generator is injected into the drinking water in the container 11 through the feed pipe 23 under the action of the air blower 22, the pressure generated by the gas pushes the valve flap of the one-way valve 5 to open, and the ozone-containing air smoothly passes through the one-way valve 5 into the drinking water. When the drinking water in the container 11 may flow back due to pressure changes or other reasons, the water exerts a reverse pressure on the valve flap of the one-way valve 5, causing the valve flap to close tightly and preventing water from flowing back into the feed pipe 23, thereby achieving the function of preventing backflow and ensuring the stable operation of the entire ozone injection system and the safety of the equipment.

[0041] As shown in Figure 1 In this embodiment, the optimized small ozone generator 21 includes a ceramic panel 211 and a high-voltage power supply 212, and the ceramic panel 211 is accommodated in a small chamber 213 formed at the middle position of the small ozone generator 21 supplied with air by the air blower 22.

[0042] In the technical solution, by placing the ceramic panel 211 at the middle position of the small chamber 213 supplied with air by the air blower 22 and matching with the high-voltage power supply 212, ozone can be efficiently generated. This design ensures sufficient ozone generation to meet the disinfection needs of a large amount of drinking water in the container 11 of the direct drinking water machine, effectively inhibits bacterial reproduction, avoids turbidity and taste deterioration of water due to bacterial growth, and guarantees the quality and safety of drinking water. The air blower 22 continuously supplies air to create a good dynamic environment for ozone generation. The flow of air helps to timely remove the heat generated during the ozone generation process, preventing local overheating from affecting the performance of the ceramic panel 211 and the high-voltage power supply 212, and prolonging the service life of the equipment. At the same time, the continuous replenishment of fresh air can ensure sufficient gas for the reaction to generate ozone, maintaining stable ozone generation efficiency.

[0043] Working principle: The high-voltage power supply 212 provides high potential for the ceramic panel 211. When the air blower 22 sends air into the small chamber 213 of the small ozone generator 21, the air flows in the small chamber 213. Under the action of high potential, the air molecules around the ceramic panel 211 are ionized. During the ionization process of the oxygen molecules in the air, part of the oxygen atoms are separated out. These oxygen atoms are extremely unstable and will quickly combine with the surrounding oxygen molecules to form ozone molecules. Since the ceramic panel 211 is located at the middle position of the small chamber 213, the flowing air is uniformly distributed around it, so that the ionization reaction can be stably carried out in a larger range, thereby efficiently generating ozone. The generated ozone flows with the air and is injected into the container 11 of the direct drinking water machine through the feed pipe 23 to disinfect the drinking water.

[0044] As shown in Figure 1 In this embodiment, the amount of ozone generated by the ozone generator is adjusted by a variable resistor connected to the high-voltage power supply 212.

[0045] In this technical solution, different sources of drinking water have different initial bacterial content and water quality. At the same time, the direct drinking water machine has different requirements for disinfection degree under different use environments and frequencies. By adjusting the amount of ozone generated by the ozone generator through the variable resistor, the disinfection intensity can be flexibly adjusted according to the actual situation. For example, when the water quality is good and the bacterial content is low, the ozone generation amount can be appropriately reduced to meet the disinfection demand and avoid excessive ozone residue; in the case of poor water quality or high use frequency, the water in the container 11 is not updated in time, and the ozone generation amount is increased to ensure sufficient disinfection, inhibit bacterial reproduction, maintain good quality of drinking water, and avoid problems such as turbidity and poor taste of the water.

[0046] Although ozone has strong disinfection ability, excessive ozone may have adverse effects on human health and the equipment itself. Reasonable adjustment of the amount of ozone can control it within a safe range, ensuring disinfection effect and not causing potential threat to user health due to excessive ozone residue, while avoiding corrosion of high-concentration ozone on internal components of the direct drinking water machine, prolonging the service life of the equipment. Providing the function of adjustable ozone amount for users enhances the intelligence and individualization of the direct drinking water machine. Users can adjust the ozone generation amount according to their own preferences for drinking water quality and actual use experience, improve the use experience, and meet the diversified needs of different users.

[0047] Working principle: The variable resistor is connected to the high-voltage power supply 212, and its working principle is based on Ohm's law. When the resistance of the variable resistor changes, the current in the circuit also changes accordingly. The high-voltage power supply 212 provides high potential for the ceramic panel 211 of the ozone generator to generate ozone, and the change of current directly affects the power obtained by the ceramic panel 211. Because the power is proportional to the square of the current, the change of current will change the ability of the ceramic panel 211 to generate ozone. When it is necessary to increase the amount of ozone generated, the resistance of the variable resistor is reduced, the current in the circuit is increased, the power obtained by the ceramic panel 211 is increased, and more ozone is generated; on the contrary, the resistance of the variable resistor is increased, the current is reduced, the power of the ceramic panel 211 is reduced, and the amount of ozone generated is reduced. In this way, the amount of ozone generated by the ozone generator is accurately adjusted to adapt to different use conditions and needs.

[0048] Embodiment 2:

[0049] This embodiment provides a double-switch direct drinking water machine, which has the following technical features in addition to the technical solutions of the above embodiments.

[0050] As shown in Figure 1 In this embodiment, the base end of the water outlet pipe b142 is provided with a heater 6.

[0051] In this technical solution, in daily life, users have various temperature requirements for drinking water. The base end of the water outlet pipe b142 is provided with a heater 6, which can provide hot water for users. Whether it is used for brewing coffee, tea and other beverages, or meets the demand for drinking hot water in cold weather, or performs some simple cooking operations that require hot water, the water outlet pipe b142 can obtain hot water with appropriate temperature, greatly enriching the functions of the direct drinking water machine and improving the user's convenience and experience. The addition of the heating function enables the direct drinking water machine to adapt to more use scenarios, and compared with ordinary drinking water machines that can only provide normal temperature water or cold water, it has higher practicality.

[0052] Working principle: The heater 6 is installed at the base end of the water outlet pipe b142, and its working principle is based on the conversion of electrical energy into heat energy. When the heater 6 is connected to the power supply, the current passes through the internal heating element (such as resistance wire, etc.). According to Joule's law, heat is generated when current passes through resistance, and the temperature of the heating element rises rapidly. When the water in the water outlet pipe b142 flows through the heater 6, heat transfer occurs between the high-temperature heating element and the water. Heat is transferred from the heating element to the water, causing the water temperature to gradually rise. By reasonably designing the power and heating time of the heater 6, and controlling the water flow rate, the water can be heated to the appropriate temperature for user use. For example, when the user opens the dispensing faucet 15 of the water outlet pipe b142, the water flows through the heater 6, and the heater 6 heats according to the preset power to ensure that the water flowing out reaches the user's desired hot water temperature.

[0053] As Figure 1 shown in the embodiment, the base end of the water outlet pipe c143 is provided with an evaporator 7, and the evaporator 7 is connected in series with a compressor 8 and a condenser 9.

[0054] In the technical solution, when it is hot weather or the user prefers cold drinks, the base end of the water outlet pipe c143 is provided with an evaporator 7 and related refrigeration structure, which can cool the drinking water flowing through the water outlet pipe c143, and provide the user with cool drinking water. The user's demand for drinking water of different temperatures is met, the function of the direct drinking water machine is enriched, and the user's experience in summer or high-temperature environment is improved. A suitable low-temperature environment helps to slow down the reproduction speed of microorganisms in water, prolongs the shelf life of drinking water, and through the cooling function, the drinking water is maintained at a lower temperature, which can inhibit the breeding of bacteria to a certain extent, maintain the clarity and taste of the water, ensure the quality and safety of the drinking water, and avoid the deterioration of the water and the deterioration of the taste due to the excessive temperature of the water.

[0055] Working principle: the compressor 8 driven by the engine starts to work, and the gaseous refrigerant in the evaporator 7 is extracted. At this time, the pressure in the evaporator 7 is reduced, so that the heat of the drinking water flowing through the base end of the water outlet pipe c143 evaporator 7 is absorbed, and the water temperature is reduced. This is because the pressure in the evaporator 7 is reduced, the boiling point of the refrigerant is lowered, the refrigerant is rapidly vaporized at low temperature, and the heat of the surrounding environment (i.e. drinking water) is absorbed, realizing the cooling of the water. The compressor 8 compresses the extracted gaseous refrigerant, so that its pressure and temperature are increased, and it becomes high-pressure gaseous refrigerant. Subsequently, the high-pressure gaseous refrigerant is pressed into the condenser 9. The high-pressure gaseous refrigerant exchanges heat with the external environment in the condenser 9. The condenser 9 usually adopts structures such as heat dissipation fins or fans to increase the contact area with the external air. The refrigerant releases heat in the condenser 9, and the temperature is reduced and gradually liquefied. This part of the released heat is dissipated to the surrounding environment, realizing the heat transfer of the refrigeration system. The liquefied refrigerant flows back to the evaporator 7 to start the next round of refrigeration cycle. Such circulation continues to cool the drinking water in the water outlet pipe c143, so that the user can obtain cool drinking water when opening the dispensing faucet 15 of the water outlet pipe c143.

[0056] The embodiments of the present application are described above in combination with the drawings, and the embodiments and features in the embodiments of the present application can be combined with each other without conflict, and the present application is not limited to the above-mentioned specific embodiments. The above-mentioned specific embodiments are only illustrative, not limiting, and those skilled in the art can make many forms under the inspiration of the present application without departing from the scope of the present application and the protection scope of the claims.
