Description

Technical Field

[0001] The utility model relates to the field of microwave detection, and particularly to a microwave device that can be installed on a faucet. Background Art

[0002] Faucets can be divided into induction faucets and non - induction faucets. Among them, induction faucets are usually infrared - induction ones. They can emit infrared rays externally. When a hand enters the induction area, the infrared rays are blocked by the hand and reflected back to the receiving tube of the infrared sensor, thus realizing automatic induction of water outflow. Since infrared - induction faucets need to emit infrared rays, it is necessary to open a window on the faucet, which will, to a certain extent, affect the appearance beauty of the faucet product. Moreover, some materials are not suitable for opening windows. Therefore, infrared sensors are only applicable to faucets of some materials. Also, existing infrared - induction faucets are usually only applicable to places where cold water is supplied and are not applicable to places where both cold and hot water need to be supplied, so their application scope is limited.

[0003] Because induction faucets can sense water outflow without the user touching the faucet, they can reduce contact transmission and are more conducive to health and safety, so they are widely used in public places. Although induction faucets are more conducive to health and safety compared to non - induction faucets, not all water - using occasions are equipped with induction faucets, and non - induction faucets still exist in large numbers in daily life. If the non - induction faucet is removed and reinstalled as an induction faucet, the original faucet will be left idle and wasted, and the new induction faucet will greatly increase the use cost. Therefore, if you want to transform and upgrade a non - induction faucet, you cannot completely adopt the direct replacement method. Summary of the Utility Model

Detailed implementation manners

[0029] The following embodiments are further explanations and supplements to the present utility model and do not constitute any limitation to the present utility model.

[0030] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 shown, the microwave device of the present utility model includes an induction end 10 and a control end 20. Among them, the induction end 10 is used for induction and can be installed at a suitable installation position such as the side or bottom of the washbasin 30 to sense the hand movements of the user through microwaves. The control end 20 is electrically connected to the induction end 10 through the cable 11 and is connected to the water inlet pipeline 50 of the existing faucet 40. It is used to control the automatic water outlet and automatic water shut-off of the existing faucet 40 according to the signal of the induction end 10, so that the existing non-inductive faucet 40 is extended with the function of inductive water outlet.

[0031] For the convenience of installation without changing the structure of the existing faucet 40, the control end 20 is provided with a water inlet 21, a water outlet 22, an electronic valve module 23 and a control module 24. The water inlet 21 and the water outlet 22 are respectively used for connecting with the water inlet pipeline 50 of the existing faucet 40, so as to install the control end 20 in the existing water inlet pipeline 50. The electronic valve module 23 is arranged between the water inlet 21 and the water outlet 22, and it can control the water flow path between the water inlet 21 and the water outlet 22. When the electronic valve module 23 is opened, a water flow path is formed between the water inlet 21 and the water outlet 22. When the electronic valve module 23 is closed, the water flow path between the water inlet 21 and the water outlet 22 is blocked. The electronic valve module 23 is connected to the control module 24, and the control module 24 can receive the signal of the sensing end 10 through the cable 11. Therefore, the control module 24 can control the opening and closing of the electronic valve module 23 according to the signal of the sensing end 10, so as to control the on-off of the water inlet pipeline 50 to realize the induction water outlet control of the faucet 40.

[0032] When the sensing end 10 detects a hand movement in the sensing area, the control module 24 controls the electronic valve module 23 to open according to the signal of the sensing end 10. At this time, a water flow path is formed between the water inlet 21 and the water outlet 22, and the water in the water inlet pipeline 50 can flow through the control end 20 and then flow to the connected faucet 40, so that the faucet 40 realizes the function of induction water outlet.

[0033] When the sensing end 10 detects that the user's hand has left the sensing area, the control module 24 controls the electronic valve module 23 to close according to the signal of the sensing end 10. At this time, the water flow path between the water inlet 21 and the water outlet 22 is blocked, and water cannot flow out of the faucet 40, so that the faucet 40 realizes the function of induction water shut-off.

[0034] When the microwave device of the present utility model is installed in the water inlet pipeline 50 of the existing non-inductive faucet 40, during actual use, the faucet 40 can be placed in the open state. In this way, when the user's hand enters the sensing area of the sensing end 10, the faucet 40 will automatically discharge water, and when the user's hand exits the sensing area, the faucet 40 will automatically shut off the water. If the faucet 40 is always in the closed state, no matter how it is sensed, the faucet 40 cannot discharge water. The specific method for the sensing end 10 to detect the user's hand movement is not limited. For example, it can be monitored by the microwave intensity. When the sensing end 10 detects that the intensity of the microwave signal is greater than the preset threshold, it triggers the electronic valve module 23 to open for induction water outlet; when the sensing end 10 detects that the intensity of the microwave signal changes from exceeding the preset threshold to being lower than the preset threshold within a certain time (such as within 1 second), it triggers the electronic valve module 23 to close for induction water shut-off.

[0035] Furthermore, to avoid water discharge due to false induction, water discharge overtime protection can be set. For example, when the control module 24 continuously determines that there is a hand movement in the induction area, water discharge overtime protection is entered when the continuous water discharge exceeds 1 minute. At this time, the control electronic valve module 23 is forced to close to stop water supply until no hand movement is detected within a certain time (such as within 5S), then the overtime protection is exited. Through the overtime protection, continuous water discharge caused by false induction can be avoided, eliminating potential safety hazards.

[0036] During installation and use, the control end 20 and the induction end 10 can be set at different positions, and their specific installation positions can be determined according to the actual scenario. The induction end 10 uses microwave induction, and since microwaves have penetrability, the induction end 10 can be hidden and installed inside the washbasin 30, distributed on the inner and outer sides of the washbasin 30 with the faucet 40. That is, the induction end 10 is usually hidden and installed on the wall surface of the washbasin 30 inside the cabinet of the washbasin 30.

[0037] For convenience of description, the side of the washbasin 30 facing the faucet 40 is called the outer side, and its corresponding wall surface is called the outer wall surface; the side of the washbasin 30 facing away from the faucet 40 is called the inner side, and its corresponding wall surface is the inner wall surface.

[0038] Normally, users stand in front of the washbasin 30 and use it facing the faucet 40. To improve the induction accuracy of the induction end 10, preferably, the induction end 10 can be installed in the first area S1 or the second area S2 of the washbasin 30. The first area S1 refers to the inner wall surface area of the washbasin 30 where the faucet 40 is located, and the second area S2 refers to the inner wall surface area of the washbasin 30 opposite to the first area S1.

[0039] In addition, to avoid water accumulation in the washbasin 30 affecting microwave induction, the induction end 10 should be installed as much as possible at the high points of the first area S1 and the second area S2. In other words, the induction end 10 should be as close as possible to the top of the washbasin 30 and away from the bottom of the washbasin 30.

[0040] The control end 20 can be installed according to the situation of the water inlet pipe 50 of the faucet 40. It is installed between the water inlet pipes 50 to control the on-off of the water inlet pipes 50, thereby controlling the water discharge and water cut-off of the faucet 40.

[0041] In this application, such as Figure 2 、 Figure 4As shown, the water inlet pipeline 50 indicates the water inlet pipeline outside the wall where the pipe is installed, which includes a first pipe section 51 extending out of the wall and a second pipe section 52 connected to the faucet. The water supply pipeline (such as the water pipe in the wall) can supply water to the faucet through the water inlet pipeline 50. The first pipe section 51 can be a single pipe or multiple pipes connected together. The second pipe section 52 can also be a single pipe or multiple pipes connected together. In the prior art, the first pipe section 51 and the second pipe section 52 are detachably connected. For example, they are usually connected together by threads. In this solution, the control end 20 is used to be connected between the first pipe section 51 and the second pipe section 52, so as to be installed in the existing water inlet pipeline 50 to expand the functions of the faucet. Specifically, the water inlet 21 is used to connect to the first pipe section 51, and the water outlet 22 is used to connect to the second pipe section 52.

[0042] Further, for the convenience of microwave detection, the induction end 10 is provided with a microwave sensor.

[0043] Further, for the convenience of installing the induction end 10 at the place of use, the induction end 10 is provided with a fixing mechanism that can fix the induction end 10 at the place of use.

[0044] Further, since it is usually inconvenient to drill holes in the tabletop, for the convenience of installation, the induction end 10 is fixed to the washbasin 30 by gluing. Specifically, the induction end 10 is provided with a housing 12, the housing 12 can accommodate the microwave sensor, and at least one side of the housing 12 is provided with a joint portion 15 extending along a plane or a curved surface, and the joint portion 15 can be attached to the surface of the tabletop. The joint portion 15 constitutes the fixing mechanism, and it can be attached to the place of use through an adhesive. The adhesive can be a material with adhesiveness such as 3M glue or glass glue. The shape and size of the joint portion 15 can be set as needed. When its area is larger, the attachment ability is stronger, and the induction end 10 is less likely to fall off. In some other embodiments, the induction end 10 can also be fixed to the washbasin 30 by vacuum adsorption. At this time, a suction cup structure can be provided at the corresponding position of the induction end 10.

[0045] Further, in some embodiments, the microwave sensor of the induction end 10 can be arranged on the side surface of the housing 12 facing the joint portion 15. In this way, when the joint portion 15 is attached and installed on the washbasin 30, the microwave sensor is attached to the tabletop, and the induction accuracy can be improved.

[0046] Further, considering the need to adjust the antenna irradiation direction and angle of the microwave sensor, in some embodiments, when installing the joint portion 15, the antenna irradiation direction and angle of the microwave sensor can be adjusted by raising or lowering the joint portion 15. For example, when setting adhesive on the back of the joint portion 15, if the adhesive is thick at one end and thin on one side, the joint portion 15 will be higher at one end and lower at the other end after pasting, thus adjusting the antenna of the microwave sensor to a suitable position; or the joint portion 15 can be designed into a structure with adjustable height, so that the antenna direction of the microwave sensor can be adjusted to a suitable angle.

[0047] Further, in some embodiments, an adjustment mechanism can also be provided in the housing 12. The adjustment mechanism is connected to the microwave sensor, and the antenna irradiation direction and angle of the microwave sensor can be adjusted through the adjustment mechanism. For example, the adjustment mechanism can be set as a universal ball structure that can be stopped at any time. The microwave sensor is fixedly arranged on the universal ball structure. When adjusting the universal ball structure through a structure such as a handle that is convenient for adjustment, the microwave sensor moves accordingly. In this way, the antenna irradiation direction and angle of the microwave sensor can be conveniently adjusted. The specific structure of the adjustment mechanism is not limited. It can refer to known technologies as long as it can drive the microwave sensor to move to adjust the antenna irradiation direction and angle and can fix the finally adjusted state.

[0048] Further, for convenient wiring connection, the sensing end 10 is provided with a fixedly arranged cable 11. One end of the cable 11 is connected to the microwave sensor and fixedly arranged on the sensing end 10, and the other end of the cable 11 is provided with an electrical connection terminal 13. The electrical connection terminal 13 can be a known terminal. Correspondingly, a sensor interface 25 is provided at the control end 20, and the sensor interface 25 is matched with the electrical connection terminal 13. The cable 11 can be detachably connected to the sensor interface 25 through the electrical connection terminal 13.

[0049] Further, in some embodiments, to facilitate the adjustment of the sensitivity of inductive water discharge, a sensitivity adjustment button 14 is provided at the sensing end 10. The sensitivity adjustment button 14 can be set to cycle through preset sensitivity levels by pressing. For example, when the induction device is powered on and working, long pressing the sensitivity adjustment button 14 enters the adjustment mode, and short pressing the sensitivity adjustment button 14 cycles through the sensitivity levels. After releasing the press for a certain period of time, the currently selected sensitivity level takes effect.

[0050] Further, to facilitate the user to view the working condition of the microwave device, an indicator light 16 can be provided on the sensing end 10. The indication form of the indicator light 16 can be set as needed, and this embodiment does not limit it. For example, different sensitivities can be indicated by different colors, and the power level can be indicated by different flashing modes.

[0051] Further, in some embodiments, the control end 20 includes a housing 26, and the shape of the housing 26 is not limited.

[0052] A water inlet pipe member 27 and a water outlet pipe member 28 are installed on the housing 26.

[0053] A part of the water inlet pipe member 27 is exposed outside the housing 26 to form a water inlet 21, and a part of the water inlet pipe member 27 is installed in the housing 26.

[0054] A part of the water outlet pipe member 28 is exposed outside the housing 26 to form the water outlet 22, and a part of the water outlet pipe member 28 is installed in the housing 26.

[0055] The electronic valve module 23 is arranged in the housing 26, and a known solenoid valve or motor is selected. One end of the electronic valve module 23 is connected to the water inlet pipe member 27, and the other end is connected to the water outlet pipe member 28, so as to form a water flow channel inside the housing 26 and control the on-off of the channel. In this embodiment, the electronic valve module 23 preferably uses a solenoid valve. In other embodiments, the electronic valve module 23 can select a motor assembly, and control the movement of a closing member arranged between the water inlet pipe member 27 and the water outlet pipe member 28 by the forward or reverse rotation of the motor, so as to control the on-off of the water flow.

[0056] The control module 24 is arranged inside or on the housing 26, and can be specifically arranged according to needs. Preferably, the control module 24 is arranged inside the housing 26.

[0057] During installation, the water inlet pipe member 27 and the water outlet pipe member 28 are respectively connected to the water inlet pipeline 50 of the faucet 40, so as to install the control end 20 on the water inlet pipeline 50 communicating with the faucet 40. More specifically, as Figure 2 shown, the water inlet pipe member 27 is connected to the first pipe section 51 of the water inlet pipeline 50, and the water outlet pipe member is connected to the second pipe section 52 of the water inlet pipeline 50. In this way, the control end 20 can be installed in the water inlet pipeline 50 to control the on-off of the water inlet pipeline 50, so as to control the water outlet and water cutoff of the faucet 40.

[0058] In some embodiments, the water inlet pipe member 27 and the water outlet pipe member 28 can be respectively set to one. In this case, the water inlet pipe member 27 and the water outlet pipe member 28 are usually connected to the cold water pipe of the water inlet pipeline 50. This embodiment is applicable to faucets that only need to discharge cold water.

[0059] In some embodiments, as Figure 3As shown, the water inlet fitting 27 includes a first water inlet fitting 271 and a second water inlet fitting 272, and the water outlet fitting 28 includes a first water outlet fitting 281 and a second water outlet fitting 282. The first water inlet fitting 271 and the first water outlet fitting 281 are used to connect to the cold water pipe of the water inlet pipeline 50, and the second water inlet fitting 272 and the second water outlet fitting 282 are used to connect to the hot water pipe of the water inlet pipeline 50. Correspondingly, the electronic valve module 23 is connected between the first water inlet fitting 271 and the first water outlet fitting 281, and between the second water inlet fitting 272 and the second water outlet fitting 282.

[0060] Among them, the cold water pipe and the hot water pipe are usually relatively independent pipes, which respectively include a first pipe section 51 and a second pipe section 52. As Figure 4 shown, during installation, the first water inlet fitting 271 is connected to the first pipe section 51 of the cold water pipe, and the first water outlet fitting 281 is connected to the second pipe section 52 of the cold water pipe; the second water inlet fitting 272 is connected to the first pipe section 51 of the hot water pipe, and the second water outlet fitting 282 is connected to the second pipe section 52 of the hot water pipe. In this way, the control end 20 can be installed in the water inlet pipeline 50 with cold water pipe and hot water pipe to control the on-off of the cold water pipe and the hot water pipe, so as to retrofit the faucet with cold and hot water. Through induction, the faucet can be controlled to automatically discharge cold and hot water.

[0061] Furthermore, one or more electronic valve modules 23 can be set as needed. For example, a solenoid valve can be separately set between the first water inlet fitting 271 and the first water outlet fitting 281, and a solenoid valve can be separately set between the second water inlet fitting 272 and the second water outlet fitting 282; or a solenoid valve can be used to simultaneously control the on-off between the first water inlet fitting 271, the first water outlet fitting 281, the second water inlet fitting 272, and the second water outlet fitting 282. When the sensing end 10 senses the user's hand movement, the electronic valve module 23 is opened, and the cold water pipeline and the hot water pipeline are all opened to form a water flow path; when the electronic valve module 23 is closed, the cold water pipeline and the hot water pipeline are blocked to close the water flow path. In this way, the automatic water discharge and water closing of the faucet can be realized through induction.

[0062] When the microwave device of the utility model is applicable to a faucet with cold and hot water functions, the water outlet temperature of the faucet is still controlled by the faucet itself. During use, the mixing ratio of cold and hot water is adjusted by means of the rotation angle of the faucet left and right, etc. to control the water outlet temperature; therefore, the microwave device of the utility model still does not change the existing structure of the faucet, but only expands the functions of inductive water discharge and inductive water closing for the faucet through structural installation.

[0063] Further, in some embodiments, for the convenience of takeover, the water inlet 21 of the water inlet pipe fitting 27 is an external thread interface, and the water outlet 22 of the water outlet pipe fitting 28 is an external thread interface. Usually, the water inlet pipe 50 of the faucet 40 uses a corrugated water pipe. One end of the corrugated water pipe is connected to the faucet 40, and the other end is connected to the water outlet point in the building. The two ends of the corrugated water pipe are usually nut connectors. Therefore, setting the water inlet 21 and the water outlet 22 as external thread interfaces can quickly connect to the existing water inlet pipe 50 of the faucet 40, thereby realizing the installation and transformation.

[0064] Further, for the convenience of power supply to the microwave device, a power supply module is provided at the control end 20.

[0065] In some embodiments, the power supply module can supply power to the electronic valve module 23, the control module 24, and the induction end 10 through dry batteries. For example, 4 AA batteries can be installed to provide 6V DC power supply.

[0066] In some embodiments, the control end 20 is further provided with a power cord. One end of the power cord is connected to the power supply module. The power supply module can supply power to the electronic valve module 23, the control module 24, and the induction end 10 through the mains when the power cord is connected to the mains, and can supply power to the electronic valve module 23, the control module 24, and the induction end 10 through dry batteries when the mains cannot provide power. In this way, AC mains power is preferentially used for power supply when there is electricity, and dry battery power supply is used when there is a power outage, so as to meet the requirements of various scenarios.

[0067] Although the present invention has been disclosed through the above embodiments, the scope of the present invention is not limited thereto. Without departing from the concept of the present invention, the above components can be replaced by similar or equivalent elements known to those skilled in the art.
