Description

Technical Field

[0001] The utility model relates to the technical field of faucets, and in particular, to an electric water heater faucet. Background Art

[0002] An electric water heater faucet is a device for heating cold water and directly discharging hot water. Currently, Chinese Patent Publication No.: CN221443515U discloses a new type of electric water heater faucet. When in use, when the handle assembly is toggled to drive the water flow guiding body to conduct, the water pressure of the water flow entering the water flow guiding body can trigger the water pressure switch to enable the electric water heater faucet to enter the heating state. However, when this type of electric water heater faucet is used in winter, if the electric water heater faucet is not in use and the water remaining in the water flow guiding body freezes, since the volume of water will increase after freezing, the frozen water will cause false triggering of the water pressure switch, that is, the electric water heater faucet will have false heating, which will also cause the heating pipe in the electric water heater faucet to dry burn and be damaged. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide an electric water heater faucet that can avoid the dry burning and damage of the electric heating pipe, that is, it realizes the protection of the electric water heater faucet.

[0004] The utility model provides an electric water heater faucet, which includes a housing, a water inlet joint, and a water pressure switch. The water inlet joint is fixed at the lower end of the housing, and the inlet end of the water inlet channel at the bottom of the housing is connected to the outlet end of the water inlet joint through a pipeline. The hot water outflow channel in the housing is communicated with the outlet end of the water inlet channel through a valve core. The water pressure switch is fixed on the inner bottom of the housing, and the detection end of the water pressure switch is communicated with the hot water outflow channel. The water pressure switch is electrically connected to the control circuit board inside the electric water heater faucet. The electric water heater faucet further includes a water flow rotor and a Hall sensor. The water flow rotor is embedded in the water inlet channel, the Hall sensor is fixed to the housing on one side of the water inlet channel, and the Hall sensor is electrically connected to the control circuit board inside the electric water heater faucet. When the water flow passes through the water inlet channel and drives the rotor body in the water flow rotor to rotate, the rotor body in the water flow rotor is used to intermittently trigger the Hall sensor.

[0005] After the present utility model adopts the above structure, when the valve core in the electric water tap is opened so that the tap water from the water inlet joint enters the hot water outlet channel through the water inlet channel, the water pressure switch can be triggered. At this time, the water pressure switch can connect the power supply of the control circuit board inside the electric water tap (after the power supply of the control circuit board inside the electric water tap is connected, the electric heating tube inside the electric water tap does not immediately start heating). In this state, since the water continuously flows through the water inlet channel, the rotor body in the water flow rotor can rotate. When the rotor body in the water flow rotor rotates, it can intermittently trigger the Hall sensor. When the Hall sensor is intermittently triggered, the control circuit board connects the power supply of the electric heating tube inside the electric water tap. At this time, the electric water tap starts to heat the tap water and hot water flows out; when the electric water tap is in an unused state and in winter, when the water remaining in the hot water outlet channel freezes and accidentally triggers the water pressure switch, since the water does not flow through the water flow rotor, that is, the rotor body in the water flow rotor cannot intermittently trigger the Hall sensor, that is, the control circuit board will not connect the power supply of the electric heating tube, thus avoiding the situation of dry burning and damage of the electric heating tube, that is, realizing the protection of the electric water tap.

[0006] In a possible implementation manner, an annular step is provided on the inner side wall of the water inlet channel, and the upper end of the water flow rotor abuts against the annular step, and the outer side wall of the water flow rotor is closely attached and sealed to the inner side wall of the water inlet channel; after adopting this structure, after the water flow rotor is embedded in the water inlet channel, the upper end of the water flow rotor can abut against the annular step, that is, the annular step can play a reliable supporting and limiting role for the water flow rotor, so that the water flow rotor can be reliably installed in the water inlet channel, and since the outer side wall of the water flow rotor is closely attached and sealed to the inner side wall of the water inlet channel, the water flow rotor can be firmly installed in the water inlet channel.

[0007] In a possible implementation manner, a groove is provided on the housing on one side of the water inlet channel, and the Hall sensor is embedded in the groove; after adopting this structure, after the Hall sensor is embedded and fixed in the groove, the Hall sensor can be reliably fixed on the housing on one side of the water inlet channel.

[0008] In a possible implementation manner, the Hall sensor is bonded and fixed to the groove; after adopting this structure, the Hall sensor can be further reliably fixed together with the groove and the housing.

[0009] In a possible implementation manner, a plurality of lugs are provided on the outer side wall of the water pressure switch and are circumferentially spaced apart, and the water pressure switch is fixed to the housing by screws passing through the lugs and threadedly connected to the housing; after adopting this structure, the water pressure switch can be reliably fixed on the inner bottom of the housing.

[0015] The present application will be further described in detail below with reference to the drawings and specific embodiments.

[0016] See Figure 1-2As shown in the figure, an embodiment of the present application discloses an electric water heater faucet, which includes a housing 1, a water inlet joint 2, and a water pressure switch 3. The water inlet joint 2 is fixed to the lower end of the housing 1, and the inlet end of the water inlet channel 11 at the bottom of the housing 1 is connected to the outlet end of the water inlet joint 2 through a pipeline. The hot water outflow channel in the housing 1 is communicated with the outlet end of the water inlet channel 11 through a valve core. The water pressure switch 3 is fixed on the inner bottom of the housing 1, and the detection end of the water pressure switch 3 is communicated with the hot water outflow channel. The water pressure switch 3 is electrically connected to the control circuit board located inside the electric water heater faucet. The electric water heater faucet further includes a water flow rotor and a Hall sensor 4. The water flow rotor is embedded in the water inlet channel 11, the Hall sensor 4 is fixed to the housing 1 on one side of the water inlet channel 11, and the Hall sensor 4 is electrically connected to the control circuit board located inside the electric water heater faucet. When water flows through the water inlet channel 11 and the rotor body in the water flow rotor is driven to rotate by the water flow, the rotor body in the water flow rotor is used to intermittently trigger the Hall sensor 4. The above water pressure switch is an existing device on the current market. For example, the switch assembly disclosed in Chinese Patent Publication No. CN118361856A, that is, it is prior art, so it will not be elaborated here. In addition, the above water flow rotor and Hall sensor are both existing components or parts on the current market, and they are prior art, so they will not be elaborated here.

[0017] When the present utility model is in use, when the valve core in the electric water tap is opened so that tap water from the water inlet joint enters the hot water outflow channel through the water inlet channel, the water pressure switch can be triggered. At this time, the water pressure switch can connect the power supply of the control circuit board inside the electric water tap (after the power supply of the control circuit board inside the electric water tap is connected, the electric heating tube inside the electric water tap does not immediately start heating). In this state, since the water continuously flows through the water inlet channel, the rotor body in the water flow rotor can rotate. When the rotor body in the water flow rotor rotates, it can intermittently trigger the Hall sensor. When the Hall sensor is intermittently triggered, the control circuit board then connects the power supply of the electric heating tube inside the electric water tap. At this time, the electric water tap starts to heat the tap water and hot water flows out. And during the process that the water continuously drives the rotor body in the water flow rotor to rotate, the electric heating tube can continuously be in the state of being powered on, that is, the electric heating tube can always be in the state of heating the tap water, which means the electric water tap can continuously be in the state of discharging hot water. In addition, the control circuit board can control the heating power of the electric heating tube according to the frequency at which the rotor body in the water flow rotor triggers the Hall sensor. That is, when the water flow rate through the water inlet channel is small, the rotation speed of the rotor body in the water flow rotor is slow, the frequency at which the Hall sensor is triggered is low, and the control circuit board controls the heating power of the electric heating tube to be relatively low. When the water flow rate through the water inlet channel is large, the rotation speed of the rotor body in the water flow rotor is fast, the frequency at which the Hall sensor is triggered is high, and the control circuit board controls the heating power of the electric heating tube to be relatively high. That is, the automatic control of the heating power of the electric heating tube is realized.

[0018] An annular step 111 is provided on the inner side wall of the water inlet channel 11. The upper end of the water flow rotor abuts against the annular step 111, and the outer side wall of the water flow rotor is closely attached and sealed with the inner side wall of the water inlet channel 11. After adopting this structure, after the water flow rotor is embedded into the water inlet channel, the upper end of the water flow rotor can abut against the annular step, that is, the annular step can play a reliable supporting and limiting role for the water flow rotor, so that the water flow rotor can be reliably installed in the water inlet channel. And since the outer side wall of the water flow rotor is closely attached and sealed with the inner side wall of the water inlet channel, the water flow rotor can be firmly installed in the water inlet channel.

[0019] A slot 12 is provided on the housing 1 on one side of the water inlet channel 11. The Hall sensor 4 is fixedly embedded in the slot 12. After adopting this structure, after the Hall sensor is fixedly embedded with the slot, the Hall sensor can be reliably fixed on the housing on one side of the water inlet channel.

[0020] The Hall sensor 4 is fixedly bonded to the slot 12. After adopting this structure, the Hall sensor can be further reliably fixed together with the slot and the housing.

[0021] A plurality of lugs 31 are arranged on the outer side wall of the water pressure switch 3 at circumferential intervals, and the water pressure switch 3 is fixed to the housing 1 by screws passing through the lugs 31 and threadedly connected to the housing 1; after adopting this structure, the water pressure switch can be reliably fixed on the inner bottom of the housing.

[0022] As described above, only the specific embodiments of the present application are given, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
