Description

TECHNICAL FIELD

[0001] The present invention belongs to a kind of fluid regulating valve, water adding mechanism with the valve and kettle containing the mechanism, in particular, mainly relates to a regulating valve combined with water pump for changing water flow direction according to the size of water flow rate, and applied in kettle for removing residual liquid in water adding pipe. BACKGROUND

[0002] Electric kettle is usually provided with water adding mechanism for guiding water into kettle body. At present, pipe is added between kettle base and kettle bottom on the market, which can realize water supply from kettle bottom to kettle body through water adding pipe to realize automatic water adding.

[0003] Generally, water tank is arranged at lower position, water adding pipe and its water outlet are arranged at higher position, and water pump is used to pump water from water tank to water adding pipe water outlet, and water is sent to kettle body through the water outlet.

[0004] In this kind of kettle, water pump inlet system is controlled by control device, which can automatically open or close water pump according to the height of water level in kettle body, so as to realize automatic control of kettle water adding.

[0005] When water is added to kettle body by water pump through water adding pipe, a certain amount of water remains in water adding pipe when water pump is closed. Otherwise, when kettle and kettle base are separated, the remaining water will flow back to the outside of kettle through water adding pipe.

[0006] In the prior art, water adding pipe and water supply pipe are arranged in upper and lower couplers respectively, and valve plate is arranged in water adding pipe of upper coupler. When water adding is not needed or kettle is separated from kettle base, valve plate is used to close water adding pipe to prevent the remaining water from flowing out of water adding pipe.

[0007] However, this structure has the following fatal defects. 1. When water adding pipe and water supply pipe are separated, water supply pipe is full of water which is not guided into kettle body, and water beads can be retained on the top end of water supply pipe. When water adding pipe and water supply pipe are connected again, water beads will penetrate out of the gap between them. To solve this problem, higher precision of parts must be required in manufacturing. 2. Valve plate is subjected to the pressure of cold and hot water for a long time in use, and impurities exist in water, which can easily form scale. Scale is easy to accumulate in valve plate, so that the surface of valve plate cannot be kept flat, and water leakage can easily occur in use. In electric kettle, once water penetrates or leaks in coupler, it is extremely dangerous, which can cause failure and even electric shock. SUMMARY

[0008] The automatic regulating valve of the present application can change the flow direction of water flow according to the flow rate of water flow, and can be applied in the water adding mechanism to control the water adding of the water adding pipe in the kettle and the water discharging in the water adding pipe.

[0009] The automatic regulating valve of the present application is realized by the following scheme:

[0010] The automatic regulating valve comprises a first valve body having a water inlet joint and a water pump water inlet joint and having a cavity in the middle, and a second valve body having a water pump water outlet joint and a water outlet joint and having a cavity in the middle, the first valve body and the second valve body respectively have a first port and a second port which are in abutment with each other, a chamber is formed between the first port and the second port, and the first port and the second port are communicated in the chamber through a first communication port and a second communication port, respectively, and a sealing mechanism is installed in the chamber to seal the first communication port.

[0011] In the above automatic regulating valve scheme, the sealing mechanism can be a valve plate to seal the first communication port, or a piston to seal the first communication port, preferably, springs are sleeved on both ends of the piston to improve the sealing pressure of the piston on the first communication port.

[0012] In this way, when the water pump water inlet joint and the water pump water outlet joint are connected to the water pump, the following effects can be achieved: when the water inlet joint is connected to water and the water pump is started, if the flow rate of water flow reaches or exceeds the threshold value, the sealing mechanism will seal the first communication port of the first valve body, and then water will continuously flow out from the water outlet joint through the water pump; if the flow rate of water flow decreases below the threshold value or the water pump is turned off, the sealing mechanism will no longer seal the first communication port of the first valve body, and then water can flow from the water outlet joint into the chamber through the second communication port of the second valve body, and flow back from the first communication port of the first valve body to the water inlet joint.

[0013] The automatic regulating valve thus obtained can automatically control water. When the water pump is started, water can be pumped from the water inlet joint to the water outlet joint through the water pump; when the water pump is turned off, water can flow back from the water outlet joint to the water inlet joint through the chamber.

[0014] The water adding mechanism of the present application is realized by the following scheme:

[0015] The water adding mechanism comprises a water inlet pipe, a water pump and a water outlet pipe, and is characterized in that it further comprises the above-mentioned automatic regulating valve, the water pump is connected between the water pump water inlet joint and the water pump water outlet joint, the water outlet joint is located at a higher position than the water inlet joint, and the water inlet pipe and the water outlet pipe are connected to the water inlet joint and the water outlet joint, respectively.

[0016] Thus, when the water pump is on, water will be pumped from the inlet pipe to the outlet pipe; when the water pump is off, water will flow back from the outlet pipe to the inlet pipe. In this way, when the water pump is off, no water or only a small amount of water will remain in the outlet pipe.

[0017] The water kettle of the present application is realized by the following scheme:

[0018] A water kettle comprising a kettle body and a kettle base, characterized in that a water filling pipe is installed in the kettle body, the water outlet of the water filling pipe is higher than the highest water level in the kettle body, and the kettle body cooperates with the kettle base to connect the water filling pipe and the water outlet pipe.

[0019] Preferably, in the above water kettle scheme, the other end of the inlet pipe is connected to a water tank.

[0020] Thus, water can be added to the kettle body through the water filling pipe by the water adding mechanism, and when the water adding is stopped, the remaining water in the water filling pipe can flow back to the inlet pipe through the water outlet pipe, and can flow back to the water tank.

[0021] In this way, when the kettle body and the kettle base are separated, there is no water in the water filling pipe, and thus there is no water leakage.

[0022] Ideally, in the above water kettle scheme, high and low water level probes are provided on the water filling pipe, and are used to obtain electrical signals representing the high and low water levels in the kettle body, respectively.

[0023] Preferably, in the above water kettle scheme, the kettle body and the kettle base are respectively provided with upper and lower couplers, a power supply device and a control device are arranged in the kettle base, the control device can send electrical signals to or obtain electrical signals from the high and low water level probes through the upper and lower couplers, respectively, and the control device controls the power supply device to supply power to the water pump according to the electrical signals provided by the high and low water level probes.

[0024] Thus, a water kettle that can automatically control water adding is obtained.

[0025] More preferably, in the above water kettle, an electric heating element is provided in the kettle body, and the control device controls the power supply device to supply power to the electric heating element through the upper and lower couplers according to the electrical signals provided by the high and low water level probes.

[0026] Thus, a water kettle that can automatically control water adding and heating is obtained.

[0027] More preferably, in the above water kettle, the upper and lower couplers are 360° ring couplers, and the water filling pipe passes through and is located at the center position of the upper coupler, and the water outlet pipe also passes through and is located at the center position of the lower coupler.

[0028] Thus, the 360° ring coupler can be used to realize the electrical connection when the kettle and the base are matched at any angle, and the water inlet pipe and the water outlet pipe will not hinder the matching at any angle.

[0029] The kettle obtained in this way can be filled with water from the bottom of the kettle body through the water inlet pipe, and the water flows out of the water outlet of the water inlet pipe and pours into the kettle body. Since the water outlet of the water inlet pipe is higher than the highest water level in the kettle body, the water poured into the kettle body cannot flow out of the kettle body through the water inlet pipe.

[0030] The automatic adjusting valve, the water adding mechanism and the kettle of the present application have two passages in the automatic adjusting valve, and can automatically select different water flow directions according to the water flow rate. Thus, the water can be sent out through the water inlet pipe and the water outlet pipe when water is being filled, and the water in the water outlet pipe can be drained into the water inlet pipe when the water filling is stopped. Therefore, the water pump can be used to pump the water from the water tank to the water outlet pipe through the water inlet pipe, and the water in the water inlet pipe can flow back to the water tank through the water outlet pipe and the automatic adjusting valve when the water pump is stopped. Thus, when the kettle body is separated from the base, there is no water in the water inlet pipe, and the problem of water leakage does not exist.

[0031] The kettle of the present application has no valve disc in the water inlet pipe to close the water when the kettle body is separated from the base. Compared with the prior art, the structure is extremely simple, and the water-proof performance is better. The valve disc is not easily affected by hot and cold water, and is not easily covered with scale, so that the sealing performance of the valve disc does not decrease rapidly, and the service life of the product is prolonged.

[0032] During use of the kettle, the temperature of the water inlet pipe rises when the electric heating element generates heat, and the heat from the electric heating element, the bottom of the kettle body and the hot water. The temperature of the water inlet pipe rises, which is beneficial to keeping the inner wall of the water inlet pipe relatively dry. When the kettle body is separated from the base, the coupler is not affected by water, so that the safety of electricity use is further ensured.

[0033] In addition, the change of the water flow direction of the automatic adjusting valve depends on the water flow rate. When the water pump is closed, the water flow rate becomes small or even 0. At this time, the closing mechanism returns to the original position, and the water flows from the water outlet to the water inlet through the chamber. The change of the water flow direction does not need to be affected by the control device, so that the control of the control device becomes simpler, and only the opening and closing of the water pump needs to be controlled.

[0040] Embodiment one: referring to Figure 1 and Figure 2 The automatic adjusting valve D of the embodiment, comprising a first valve body 1 with a water inlet joint 11 and a water pump water inlet joint 12 and having a cavity in the middle, and a second valve body 2 with a water pump water outlet joint 21 and a water outlet joint 22 and having a cavity in the middle, the first valve body 1 and the second valve body 2 respectively have a first port 13 and a second port 23 which are mutually butted, a cavity a is formed between the first port 13 and the second port 23, and the first port 13 and the second port 23 are communicated in the cavity a through a first communication port 14 and a second communication port 24, a valve piece 3 is installed in the cavity a, and the first communication port 14 can be closed by the valve piece 3.

[0041] Referring to Figure 5 The water adding mechanism of the embodiment, comprising a water inlet pipe A, a water pump B, a water outlet pipe C and an automatic adjusting valve D, the water pump B is connected between the water pump water inlet joint 12 and the water pump water outlet joint 21, the water outlet joint 22 is at a position higher than the water inlet joint 11, and the water inlet pipe A and the water outlet pipe C are connected with the water inlet joint 11 and the water outlet joint 22 respectively.

[0042] Referring to Figure 6 The kettle comprises a kettle body E, a kettle base F and a water tank H and a water adding mechanism, wherein the kettle body E is installed with a water adding pipe G, the water adding pipe G water outlet is higher than the highest water level in the kettle body E, and the kettle body E and the kettle base F are matched through a coupler to realize the communication of the water adding pipe G and the water outlet pipe C.

[0043] Thus, when the water pump B is turned on, water is pumped from the water tank H by the water pump B from the inlet pipe A to the outlet pipe C, if the water flow rate reaches or exceeds the threshold, the valve plate 3 will be subjected to the downward force of the lower air pressure and the downward force of the upper water pressure, and the first communication port 14 of the first valve body will be closed, thus, water will continuously flow out of the outlet pipe C through the water pump, and flow into the inside of the kettle body E through the water filling pipe G, when the water flow rate drops below the threshold or the water pump B is turned off, the valve plate 3 will no longer close the first communication port 14 of the first valve body 1, thus, the remaining water in the water filling pipe G can enter the chamber a through the second communication port 24 of the second valve body 2 from the outlet pipe C, and flow out of the first communication port 14 of the first valve body 1 to the inlet pipe A, and then flow back to the water tank H through the inlet pipe A, thus, there is no remaining water in the water filling pipe G, achieving the purpose of water outlet and drainage.

[0044] The embodiment of closing the first communication port by the valve plate has the characteristic of simpler structure.

[0045] Embodiment two: referring to Figure 3 and Figure 4 The automatic regulating valve D of the embodiment comprises a first valve body 1 having an inlet joint 11 and a water pump inlet joint 12 and having a cavity in the middle, and a second valve body 2 having a water pump outlet joint 21 and an outlet joint 22 and having a cavity in the middle, the first valve body 1 and the second valve body 2 respectively have a first port 13 and a second port 23 which are mutually connected, a chamber a is formed between the first port 13 and the second port 23, and the first port 13 and the second port 23 are connected in the chamber a through a first communication port 14 and a second communication port 24 respectively, a piston 3 is installed in the chamber a, springs 4 and 5 are sleeved on both ends of the piston 3, and the first communication port 14 can be closed by the piston 3.

[0046] Referring to Figure 5 The water adding mechanism of the embodiment comprises an inlet pipe A, a water pump B, an outlet pipe C, and an automatic regulating valve D, the water pump B is connected between the water pump inlet joint 12 and the water pump outlet joint 21, the outlet joint 22 is located at a position higher than the inlet joint 11, and the inlet pipe A and the outlet pipe C are connected with the inlet joint 11 and the outlet joint 22 respectively.

[0047] Referring to Figure 6 The kettle comprises a kettle body E, a kettle seat F, a water tank H, and a water adding mechanism, wherein the kettle body E is installed with a water filling pipe G, the water outlet of the water filling pipe G is higher than the highest water level in the kettle body E, and the kettle body E and the kettle seat F are coupled to realize the communication of the water filling pipe G and the outlet pipe C.

[0048] Thus, when the water pump is on, water is pumped from the water tank H by the water pump B from the inlet pipe A to the outlet pipe C, if the water flow rate reaches or exceeds the threshold, the piston 3 will be subjected to the downward force of the lower air pressure and the downward force of the upper water pressure, and will close the first communication port 14 of the first valve body 1, thus, water will continuously flow out from the outlet pipe C through the water pump, and flow into the inside of the kettle body E through the water filling pipe G, when the water flow rate drops below the threshold or the water pump B is turned off, the valve plate 3 will no longer close the first communication port 14 of the first valve body 1, thus, the remaining water in the water filling pipe G can enter the chamber a through the second communication port 24 of the second valve body 2 from the outlet pipe C, and flow back out from the first communication port 14 of the first valve body 1 to the inlet pipe A, and flow back to the water tank H through the inlet pipe A, thus, there is no longer any remaining water in the water filling pipe G, and the purposes of water outlet and water discharge are achieved.

[0049] The embodiment of closing the first communication port by the piston and the spring not only has a simple structure, but also allows the threshold to be adjusted, i.e. when the spring has a larger elastic coefficient, the water flow needs to be larger in order to be closed by the piston.
