[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0030] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the present invention.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0032] like Figure 1-7 The pressure-controlled water heater starting device shown includes a pressing assembly 10 and a water flow detector. The pressing assembly 10 includes a mounting seat 11 and a sealing valve. The mounting seat 11 can be installed at the water outlet end 21 of the water outlet pipe.

[0033] Specifically, a mounting cavity 111 is defined within the mounting base 11. The sealing valve includes a valve body 13 and a valve core 14, with the valve body 13 being sealed and inserted into the mounting cavity 111. A sealing cavity 134 is defined within the valve body 13, with the valve core 14 being movably inserted into the sealing cavity 134. An inlet 131 is defined at one end of the sealing cavity 134, while an outlet 132 is defined at the other end. The outer wall of the valve core 14 seals against the inner wall of the sealing cavity 134.

[0034] In addition, one end of the valve core 14 is formed as a pressure-receiving end, and the other end of the valve core 14 is formed as a pressure-applying end; the pressure-receiving end is used to drive the valve core 14 to move close to the outlet 132 when subjected to external force, so that the pressure-applying end applies pressure to the gas in the sealed cavity 134; the gas in the sealed cavity 134 is used to be discharged through the outlet 132 when under pressure and form an airflow, and the airflow enters the water outlet end 21 of the external water outlet pipe through the installation cavity 111 to apply air pressure to the water flow; the water flow detector can be installed in the water outlet pipe 20 to detect the direction of the water flow when the water flow is subjected to air pressure and send a water flow signal.

[0035] Based on the above structure, when using the pressure-controlled water heater starting device of the present invention, taking the application of the pressure-controlled water heater starting device to a water heater as an example, the above-mentioned mounting base 11 can be installed at the water outlet end 21 of the water outlet pipe of the water heater, specifically, it can be set at the connection position between the shower head 30 and the water outlet pipe 20.

[0036] When a user takes a shower, they first activate the water pump start switch on the water heater. The water pump starts to pump water into the water heater. The water flow sensor in the water heater detects the direction of water flow as the water flow signal flowing into the shower head 30. This water flow signal can be fed back to the water heater controller 70, which then issues a gas valve opening and ignition command, causing the water heater to start running and hot water to flow out of the shower head 30. When the user turns off the shower head 30 during a shower, there is no water flow signal in the water outlet pipe 20 to be fed back to the control system. The control system then issues a command to shut off the water pump to prevent damage to the pump.

[0037] When the user needs to start the water heater again, there is no need for the user to go to the water heater control end to start the water pump through other people or by himself / herself. The user only needs to start the water pump through the pressing component 10 integrated at the end of the shower head 30.

[0038] Specific method: First, the valve core 14 in the mounting seat 11 can be pressed, and the external force can be applied to the pressure end of the valve core 14 through the inlet 131 of the sealed cavity 134, and the valve core 14 can move toward the outlet 132 in the sealed cavity 134. The pressure end of the valve core 14 can squeeze the air inside the sealed cavity 134, and the air can be discharged through the outlet 132 to generate air pressure. The positive pressure air is pressed on the water column in the water outlet pipe 20 of the shower head 30 through the outlet 132. The pressurized water column flows in the reverse direction of the water heater. The water flow sensor can detect the reverse water inflow signal at this time. The controller 70 receives and recognizes the reverse water inflow signal and starts the water pump. At this time, the switch at the end of the shower head 30 is turned on, and the water flow begins to flow out along the outlet pipe 20 to the shower head 30. The water flow detector detects the water outlet signal, and the controller 70 can issue a gas valve opening and ignition command, and the water heater starts to run.

[0039] In this way, air pressure can be generated by mechanical pressing, which applies pressure to the water flow, causing the water flow sensor inside the machine to generate a reverse water flow signal, thereby starting the water pump to supply water. The water heater can be started again without operating the switch on the water heater port. It is easy to use, and the switch control is not easily damaged by using mechanical pressing in conjunction with the electronic controller 70.

[0040] Furthermore, the pressing assembly 10 includes an elastic member 15, one end of which abuts against the end wall of the sealed cavity 134 near the outlet 132, while the other end of the elastic member 15 abuts against the pressure-applying end. This allows the elastic member 15 to be compressed when the valve core 14 is driven toward the outlet 132 of the sealed cavity 134. When water flows normally to the showerhead 30, the reverse force provided by the water flow can drive the valve core 14 to reset. The elastic stress provided by the reset of the elastic member 15 can also quickly reset the valve core 14 and reseal it against the inlet 131 of the sealed cavity 134, preventing water leakage.

[0041] More specifically, the above-mentioned valve core 14 also includes a piston plate 141 and a connecting column 142, which connects the piston plate 141 to the sealing chamber 134, and one end of the piston plate 141 is formed as the above-mentioned pressure-bearing end, and the other end of the piston plate 141 is formed as the above-mentioned pressure-applying end. The connecting column 142 is connected to the pressure-applying end and is connected to the elastic component 15, and the end of the connecting column 142 away from the piston plate 141 can be connected to the outlet 132.

[0042] When the water pump is started, pressure is applied to the piston plate 141 of the valve core 14 through the inlet 131. The piston plate 141 then moves along the sealed cavity 134 to the outlet 132, compressing the gas within the sealed cavity 134 and generating positive pressure. At this point, the connecting post 142 connected to the piston plate 141 extends toward the outlet 132, opening the sealed cavity 134. The compressed gas within the sealed cavity 134 is then discharged through the outlet 132 to pressurize the water flow.

[0043] Of course, the connecting column 142 can be connected to the elastic component 15, which can reduce the shaking of the elastic component 15 during the compression process, and the reciprocating motion of the piston plate 141 is more stable.

[0044] It should be noted that the elastic component 15 is a spring, or can be implemented by using a structure such as an elastic rubber block in the prior art.

[0045] Furthermore, the pressing assembly 10 in this embodiment also includes a pressing member 12, and a pressing cavity 121 is provided in the pressing member 12. Specifically, one end of the pressing member 12 can be pressed by an external force to deform the pressing member 12, and the other end of the pressing member 12 is connected to the installation cavity 111 and seals the outer periphery of the external device and the inlet 131, and the above-mentioned pressing cavity 121 is connected to the inlet 131; the pressing cavity 121 can squeeze the internal gas to the inlet 131 when the pressing member 12 is compressed and deformed, so as to apply pressure to the pressed end.

[0046] During mechanical pressing, the pressing member 12 can be pressed, and the pressing member 12 can be deformed when subjected to force, squeezing the pressing cavity 121 in the pressing member 12. The gas in the pressing cavity 121 can be squeezed out after deformation and introduced through the inlet 131 of the sealing cavity 134, applying pressure to the pressure-bearing end of the valve core 14. The valve core 14 can then start to move toward the outlet 132 of the sealing cavity 134, thereby causing the gas squeezed out of the sealing cavity 134 to apply pressure to the water flow through the outlet 132.

[0047] More specifically, the pressing member 12 is made of rubber or silicone material to facilitate deformation during squeezing.

[0048] Furthermore, a plurality of annular grooves 122 may be provided on the outer surface of the pressing member 12. The plurality of annular grooves 122 may form a concave-convex surface on the outer surface of the pressing member 12, which makes it easier for the pressing member 12 to deform when subjected to force, and makes it easier for the gas in the pressing cavity 121 to be squeezed out.

[0049] Furthermore, in order to facilitate the sealing of the valve body 13 and the installation cavity 111, a mounting groove can be provided on the outer surface of the valve body 13, and a sealing ring 133 is provided in the installation groove. The sealing ring 133 is sealed with the inner wall of the installation cavity 111. In this way, a seal can be formed between the valve body 13 and the installation cavity 111 of the mounting seat 11 to prevent water leakage.

[0050] Example 2,

[0051] See also Figure 1-8The illustrated water heater includes a body 50 and the pressure-controlled water heater starting device of Example 1. The body 50 is provided with a water inlet pipe 40, a water outlet pipe 20, and a heat exchange assembly 60. One end of the water inlet pipe 40 forms the water inlet end, and the other end of the water inlet pipe 40 is connected to the water inlet of the heat exchange assembly 60. One end of the water outlet pipe 20 is connected to the water outlet of the heat exchange assembly 60, and the other end of the water outlet pipe 20 forms the water outlet end. A water flow detector is provided in the water outlet pipe 20. The water inlet pipe 40 can be connected to a water supply device. Under the action of a water pump, water from the water supply device can enter the heat exchange assembly 60 through the water inlet pipe 40. The heat exchange assembly 60 can ignite the burner in the burner to heat the water, and then discharge the water through the shower head 30 at the water outlet end 21 of the water outlet pipe.

[0052] Specifically, the pressure-controlled water heater starting device includes a pressing assembly 10 and a water flow detector. The pressing assembly 10 includes a mounting seat 11 and a sealing valve. The mounting seat 11 can be installed at the water outlet end 21 of the water outlet pipe. A mounting cavity 111 is provided in the mounting seat 11. The sealing valve includes a valve body 13 and a valve core 14. The valve body 13 is sealed and connected to the mounting cavity 111. A sealing cavity 134 is provided in the valve body 13. The valve core 14 is movably connected to the sealing cavity 134. An inlet 131 is provided at one end of the sealing cavity 134, and an outlet 132 is provided at the other end of the sealing cavity 134. The outer wall of the valve core 14 is sealed and matched with the inner wall of the sealing cavity 134.

[0053] In addition, one end of the valve core 14 is formed as a pressure-receiving end, and the other end of the valve core 14 is formed as a pressure-applying end; the pressure-receiving end is used to drive the valve core 14 to move close to the outlet 132 when driven by external force, so that the pressure-applying end applies pressure to the gas in the sealed cavity 134; the gas in the sealed cavity 134 is used to be discharged through the outlet 132 when under pressure and form an airflow, and the airflow enters the water outlet end 21 of the external water outlet pipe through the installation cavity 111 to apply air pressure to the water flow; the water flow detector can be installed in the water outlet pipe 20 to detect the direction of the water flow when the water flow is under air pressure and send a water flow signal.

[0054] Furthermore, a controller 70 may be provided in the body 50 , and the controller 70 may receive a water flow signal to control the start and stop of the water pump and the gas valve.

[0055] Based on the above structure, when the water heater is used, the mounting base 11 can be installed at the water outlet end 21 of the water outlet pipe of the water heater, specifically, at the connection position between the shower head 30 and the water outlet pipe 20 .

[0056] When a user takes a shower, they first activate the water pump start switch on the water heater. The water pump starts to pump water into the water heater. The water flow sensor in the water heater detects the direction of water flow as the water flow signal flowing into the shower head 30. This water flow signal can be fed back to the water heater controller 70, which then issues a gas valve opening and ignition command, causing the water heater to start running and hot water to flow out of the shower head 30. When the user turns off the shower head 30 during a shower, there is no water flow signal in the water outlet pipe 20 to be fed back to the control system. The control system then issues a command to shut off the water pump to prevent damage to the pump.

[0057] When the user needs to start the water heater again, there is no need for the user to go to the water heater control end to start the water pump through other people or by himself / herself. The user only needs to start the water pump through the pressing component 10 integrated at the end of the shower head 30.

[0058] Specific method: First, the valve core 14 in the mounting seat 11 can be pressed, and the external force can be applied to the pressure end of the valve core 14 through the inlet 131 of the sealed cavity 134, and the valve core 14 can move toward the outlet 132 in the sealed cavity 134. The pressure end of the valve core 14 can squeeze the air inside the sealed cavity 134, and the air can be discharged through the outlet 132 to generate air pressure. The positive pressure air is pressed on the water column in the water outlet pipe 20 of the shower head 30 through the outlet 132. The pressurized water column flows in the reverse direction of the water heater. The water flow sensor can detect the reverse water inflow signal at this time. The controller 70 receives and recognizes the reverse water inflow signal and starts the water pump. At this time, the switch at the end of the shower head 30 is turned on, and the water flow begins to flow out along the outlet pipe 20 to the shower head 30. The water flow detector detects the water outlet signal, and the controller 70 can issue a gas valve opening and ignition command, and the water heater starts to run.

[0059] In this way, air pressure can be generated by mechanical pressing, which applies pressure to the water flow, causing the water flow sensor inside the machine to generate a reverse water flow signal, thereby starting the water pump to supply water. The water heater can be started again without operating the switch on the water heater port. It is easy to use, and the switch control is not easily damaged by using mechanical pressing in conjunction with the electronic controller 70.
