Description

Technical Field

[0001] The utility model relates to a stepless temperature-adjusting purified water output device. Background Art

[0002] At present, users of household water purifiers often use a set of purified water output devices in conjunction with the water purifier for the convenience of water collection. Such purified water output devices are generally composed of a faucet and a hot tank. The purified water output by the water purifier will be input into the faucet and the hot tank respectively, and the hot purified water heated by the hot tank will also be input into the faucet. The faucet mixes different proportions of normal temperature purified water and hot purified water according to the user's operation, so that the purified water output from the faucet can achieve stepless temperature adjustment for user convenience.

[0003] Since the purified water output of household water purifiers has the characteristics of high pressure and low flow, in order to prevent the hot tank from being subjected to the water outlet pressure at all times, this type of output device often needs to install an electric control valve at the water inlet of the hot tank to limit the water flow and protect the hot tank. In the case where an electric control valve needs to be installed in front of the hot tank, in order to achieve stepless temperature control of the purified water output, it is also necessary to set electric control valves that can control the opening at the normal temperature water inlet and the hot water inlet of the faucet. Therefore, the knob / handle on the faucet of this type of output device often does not directly control the opening of each water inlet. The knob / handle is actually an electronic knob. The voltage / current changes caused by the rotation of the knob / handle. The control circuit controls the valve opening at the two water inlets according to the change in voltage / current, thereby mixing different proportions of normal temperature purified water and hot purified water to achieve stepless temperature control of purified water output.

[0004] However, the above-mentioned stepless temperature control technical solution requires the use of electronically controlled valves capable of adjusting the opening at both water inlets of the faucet, and the faucet knob / handle also needs to be an electronic knob, so the cost is extremely high. In addition, the structure of the faucet will become more complicated due to the need to design and arrange the control circuit.

[0005] Therefore, how to overcome the above-mentioned defects has become an important issue to be solved urgently by those skilled in the art. Utility Model Content

[0026] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0027] like Figures 1 to 5 As shown, a stepless temperature-controlled purified water output device comprises a faucet 1, the faucet 1 is provided with a first water inlet 2 for connecting a water purifier to purified water at room temperature and a second water inlet 3 for hot purified water, the second water inlet 3 is connected with a hot tank 4, the hot tank 4 is used to store and heat purified water, the water inlet of the hot tank 4 is also connected to the water purifier for easy access to purified water, a solenoid valve 5 for controlling water inlet is provided at the water inlet of the hot tank 4, a valve core 6 for controlling the opening of the first water inlet 2 and the second water inlet 3 is provided in the faucet 1, a knob 7 connected to the rotating core of the valve core 6 and rotating synchronously is provided on the faucet 1, a control switch 8 for controlling the opening and closing of the solenoid valve 5 is provided in the faucet 1, and a trigger structure for synchronously rotating and triggering the control switch 8 is fixed on the rotating core of the valve core 6 or the knob 7.

[0028] The purified water output device in this case directly controls the opening of the first water inlet 2 and the second water inlet 3 through the cooperation of the knob 7 and the valve core 6, thereby achieving the mixing of normal temperature purified water and hot purified water. The switch of the solenoid valve 5 is controlled by the cooperation of the control switch 8 and the trigger structure. When the rotating core of the valve core 6 and the knob 7 rotate to the specified position range, that is, when the opening of the first water inlet 2 and the second water inlet 3 reaches the specified situation, the trigger structure will also rotate to the specified position and then trigger the control switch 8, so that the solenoid valve 5 can be controlled to open so that the normal temperature purified water can enter the hot tank 4, and the hot purified water in the hot tank 4 will be delivered to the faucet.

[0029] As described above, the purified water output device of this case can control the solenoid valve 5 by setting a trigger structure on the rotating core or knob 7 of the valve core 6 in conjunction with the control switch 8, and then control whether to input purified water into the hot tank 4 for heating and storage. The valve core 6 and the knob 7 can cooperate to achieve the input mixing of different proportions of normal temperature purified water and hot purified water, thereby achieving stepless temperature control. This case does not require the use of expensive electrically controlled valves that can control the opening, nor does it require the knob / handle of the faucet to be converted into an electronic knob, and there is no need to set up a complex control circuit. Only by setting a trigger structure and a control switch 8 in conjunction with a traditional faucet structure can the purified water output with stepless temperature control be achieved. In this way, the technical solution of this case can save parts costs to a great extent compared to the prior art, and can also simplify the product structure, which can effectively improve the competitiveness of the product.

[0030] like Figures 2 to 3 As shown, preferably, the trigger structure includes a rotating member 9 fixed on the rotating core or knob 7 of the valve core 6 and rotating synchronously.

[0031] like Figures 2 to 3As shown, preferably, the control switch 8 is a contact switch, and the side surface of the rotating member 9 is in a cam shape 91.

[0032] As described above, the control switch 8 can be a contact switch. When the contact switch is used, the side of the rotating member 9 is correspondingly set to a cam shape 91. In this way, when the rotating member 9 rotates with the rotating core or knob 7, the contact switch can be triggered at a specified position through the cam structure to achieve control of the solenoid valve 5.

[0033] Preferably, the control switch 8 may also be a Hall switch, and magnets are circumferentially arranged on the side of the rotating member 9.

[0034] As mentioned above, the control switch 8 can also be a Hall switch. When the Hall switch is used, a magnet is correspondingly arranged circumferentially on the side of the rotating part 9. In this way, when the rotating part 9 rotates to a specified position along with the rotating core or the knob 7, the Hall switch can be triggered by the magnet on the side of the rotating part 9 to realize the control of the solenoid valve 5.

[0035] like Figures 2 to 4 As shown, preferably, the faucet 1 is provided with a first temperature sensor 10 for detecting the outlet water temperature, and the faucet 1 is also provided with a display module 11 for displaying the outlet water temperature. In this way, the outlet water temperature of the faucet is detected by the first temperature sensor 10 and displayed by the display module 11, so that the user can intuitively and accurately know the outlet water temperature of the faucet, thereby avoiding the user from being scalded by overheated water without knowing the outlet water temperature or the outlet water temperature not meeting the user's requirements.

[0036] like Figure 5 to Figure 6 As shown, preferably, the hot tank 4 includes a tank body 41, the wall surface of the tank body 41 is provided with an insulating layer 42 for heat insulation and heat preservation, the tank body 41 is provided with a heating pipe 43 for heating purified water, the tank body 41 is provided with a second mechanical thermostat 44 for preventing dry burning, and the tank body 41 is also provided with a third mechanical thermostat 45 or a fourth temperature sensor 48 for water temperature control.

[0037] As described above, the clean water input through the solenoid valve 5 will enter the tank body 41, and the clean water in the tank body 41 can be heated by the heating tube 43. The third mechanical thermostat 45 or the fourth temperature sensor 48 can more effectively control the start and stop of the heating tube 43 according to the clean water temperature of the tank body 41, and the insulation layer 42 can prevent the rapid loss of heat in the tank body 41, which causes the heating tube 43 to work frequently and increase energy consumption. In addition, the second mechanical thermostat 44 can timely control the heating tube 43 to stop working when dry burning occurs in the tank body 41.

[0038] like Figure 5 to Figure 6As shown, preferably, the heat insulation layer 42 is filled with heat insulation material or the heat insulation layer 42 is a vacuum layer.

[0039] like Figure 5 to Figure 6 As shown, preferably, the heating tube 43 and the second mechanical thermostat 44 are both arranged at the bottom of the tank body 41. In this way, when the amount of water in the tank body 41 is small and the heating tube 43 starts to dry-burn, the heat generated by the heating tube 43 can be quickly transferred to the second mechanical thermostat 44, thereby triggering the second mechanical thermostat 44 to stop the heating tube 43 from working.

[0040] like Figure 5 As shown, preferably, the height position of the fourth temperature sensor 48 in the tank body 41 is consistent with the water alarm water level of the tank body 41.

[0041] As described above, when the water in the tank body 41 gradually decreases due to heating and exceeds the alarm water level, the temperature detected by the fourth temperature sensor 48 will change suddenly, which is specifically manifested as a sudden drop in temperature. In this way, it is possible to determine whether the clean water in the tank body 41 is too little and lower than the alarm water level based on the temperature change detected by the fourth temperature sensor 48. In this way, the fourth temperature sensor 48 in this case also plays the role of water level detection.

[0042] like Figure 1 , Figure 5 As shown, preferably, an exhaust pipe 46 is provided on the top of the tank body 41 , and a pressure relief valve 47 is provided in the exhaust pipe 46 .

[0043] like Figure 5 As shown, preferably, the exhaust pipe 46 is a branch of the water circuit between the water outlet of the tank body 41 and the second water inlet 3 .

[0044] As described above, when the heating tube 43 heats the clean water in the tank body 41, the air pressure in the tank body 41 will also increase. By setting an exhaust pipe 46 or an exhaust branch 48 in conjunction with a pressure relief valve 47, water vapor can be discharged through the pressure relief valve 47 when the pressure is too high, thereby preventing the tank body 41 from being damaged by excessive air pressure.

[0045] like Figures 2 to 4As shown, preferably, a fixed connection seat 12 is provided in the faucet 1, and the fixed connection seat 12 is provided with a accommodating cavity 121 with an opening facing upward for the valve core 6 to be inserted therein, and two first through holes 122 are provided at the bottom of the accommodating cavity 121 for exposing the water inlet of the valve core 6 to form a first water inlet 2 and a second water inlet 3, and a side wall of the accommodating cavity 121 is provided with a water outlet channel 123 connected to the water outlet of the faucet 1, and a plug 124 is threadedly connected to the mouth of the accommodating cavity 121 for sealing the valve core 6 in the accommodating cavity 121, and the rotating core of the valve core 6 passes through the plug 124 to be exposed to the outside and connected to the knob 7 to rotate synchronously, and the control switch 8 is fixedly arranged on the fixed connection seat 12.

[0046] As described above, the fixed connection seat 12 of the present case can fix the valve core 6 through the accommodating cavity 121 and the plug 124, and at the same time realize the communication between the first water inlet 2, the second water inlet 3 and the water outlet of the faucet 1. In addition, the control switch 8 is also fixedly arranged on the fixed connection seat 12, so that the control switch 8 can be fixed at a position close to the rotating core of the valve core 6 and the knob 7, which can not only facilitate the trigger structure to trigger the control switch 8, but also make the structure inside the faucet 1 more compact.

[0047] like Figures 2 to 4 As shown, preferably, the first temperature sensor 10 is arranged at the water outlet channel 123 , so that the first temperature sensor 10 can accurately detect the outlet water temperature of the faucet 1 .

[0048] As mentioned above, this case protects a water purification output device with stepless temperature control. All technical solutions that are the same or similar to this case should be deemed to fall within the scope of protection of this case.
