Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to an electronic switch, particularly a high-temperature hot water type intelligent electronic switch. Background Art

[0002] Traditional water pump electronic switches employ a tank-type design with no drop between the inlet and outlet. While this allows for a large outlet diameter, it limits the inlet diameter, significantly impacting overall water performance. Flow detection is crucial in water pump pressure control systems. While industrial-grade flow sensors offer accurate detection, their high cost and large size restrict their use in small pressure control electronic switches. Therefore, current electronic pressure switches primarily rely on reed switch induction and Hall effect sensor induction for flow detection. However, ordinary electronic switches generally lack buffer structures, making them susceptible to water hammer effects in pipelines, which can shorten pipeline lifespan and compromise reliability and stability. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a high-temperature hot water type intelligent electronic switch that can eliminate water hammer effects and operate reliably and stably.

[0004] The objective of this utility model can be achieved through the following technical solution: a high-temperature hot water type intelligent electronic switch, comprising a housing with a cavity in the middle, a water inlet at the lower end of the housing, a water outlet at the upper end of the housing, a check valve that can move up and down provided on the inner side of the water inlet, a magnet fixedly connected to the check valve, a circuit board provided on the housing, a reed switch connected to the circuit board and the reed switch capable of sensing the magnet, characterized in that an elastic diaphragm is provided inside the housing, the elastic diaphragm dividing the cavity of the housing into a pressure chamber and a buffer chamber, the water inlet and the water outlet being connected to the pressure chamber.

[0005] This high-temperature hot water intelligent electronic switch is installed on the pipeline. During operation, the circuit board adjusts the output frequency of the controller in real time through logic calculations based on the signals from the check valve and pressure sensor. This adjusts the operating speed of the water pump motor, ensuring that the water pressure inside the housing remains the same as the set value, thus achieving constant pressure water supply. When water flows through the inlet and pushes open the check valve to enter the cavity, the diaphragm deforms under water pressure, compressing the spring and displacing the push rod. This creates a buffer cavity within the head, eliminating water hammer and providing reliable and stable operation.

[0006] In the aforementioned high-temperature hot water type intelligent electronic switch, a cover is provided on the outside of the buffer cavity. The cover is fixedly connected to the housing. A spring is provided inside the cover, with one end of the spring abutting against the cover and the other end abutting against the elastic diaphragm. By setting the spring, the restoring effect of the elastic diaphragm is improved, thereby enhancing the buffering effect.

[0007] In the aforementioned high-temperature hot water type intelligent electronic switch, a pressure sensor is fixedly connected to the inner end of the water outlet, and the pressure sensor can sense the pressure inside the pressure chamber. By setting up the aforementioned pressure sensor to sense the pressure in the pressure chamber, the safety and reliability of use are improved.

[0008] In the aforementioned high-temperature hot water type intelligent electronic switch, a force seat is fixedly connected to the middle of the elastic diaphragm, a positioning protrusion is provided on the outer side of the force seat, a connecting post is fixedly connected to the inner end face of the cover, and both ends of the spring are sleeved on the positioning protrusion and the connecting post. The placement of the spring's two ends on the positioning protrusion and the connecting post provides good positioning for the spring and prevents spring misalignment.

[0009] In the aforementioned high-temperature hot water type intelligent electronic switch, a metal heat sink is fixedly connected to one side of the housing, and a sealing ring is provided between the metal heat sink and the housing. By setting up the metal heat sink and the sealing ring, the heat dissipation effect is improved, while preventing water leakage and extending the service life.

[0010] In the aforementioned high-temperature hot water type intelligent electronic switch, a second metal heat sink is provided on the outer side of the first metal heat sink, and a boss is provided on the outer side of the second metal heat sink. A heat dissipation hole is provided in the middle of the second metal heat sink, and the heat dissipation hole matches the boss, with the boss passing through the heat dissipation hole. By embedding the boss into the heat dissipation hole, the first and second metal heat sinks are positioned, resulting in advantages such as simple structure, good positioning effect, and good heat dissipation effect.

[0011] In the aforementioned high-temperature hot water type intelligent electronic switch, a control box is provided on the other side of the housing, and the circuit board is located inside the control box. The circuit board being housed within the control box offers advantages such as good protection, reliable structure, and convenient assembly.

[0012] In the aforementioned high-temperature hot water type intelligent electronic switch, the check valve is equipped with a guide post, one end of which is fixedly connected to the check valve, and the other end of which is inserted into the water inlet. By setting the guide post, the rise and fall of the check valve has a better guiding effect, while also increasing the weight of the check valve and improving the check valve's check efficiency.

[0013] Compared with existing technologies, this high-temperature hot water type intelligent electronic switch has the following advantages:

[0014] 1. When water flows through the inlet and pushes open the check valve to enter the cavity, the diaphragm deforms and squeezes the spring under the action of water pressure when water flows through the shell, and the push rod is displaced, so that a buffer cavity is formed in the head body, which can eliminate the water hammer effect and has the advantages of reliable and stable operation.

[0015] 2. A spring is installed inside the cover. One end of the spring abuts against the cover and the other end abuts against the elastic diaphragm, which improves the restoring effect of the elastic diaphragm and thus improves the buffering effect.

[0016] 3. By setting up a metal heat sink and sealing ring, the heat dissipation effect is improved, while preventing water leakage and extending service life;

[0017] 4. The circuit board is located inside the control box, which provides good protection for the circuit board and has the advantages of reliable structure and convenient assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figure 1 and 2As shown, a high-temperature hot water type intelligent electronic switch includes a housing 1 with a cavity in the middle. The lower end of the housing 1 is a water inlet 1a, and the upper end of the housing 1 is a water outlet 1b. A check valve 2 that can move up and down is provided inside the water inlet 1a. A magnet 3 is fixedly connected to the check valve 2. A circuit board 4 is provided on the housing 1. The circuit board 4 is connected to a reed switch, and the reed switch can sense the magnet 3. The key feature is that an elastic diaphragm 5 is provided inside the housing 1, which divides the cavity of the housing 1 into a pressure chamber 1c and a buffer chamber 1d. The water inlet 1a and the water outlet 1b are connected to the pressure chamber 1c. A cover 6 is provided on the outside of the buffer chamber 1d, and the cover 6 is fixedly connected to the housing 1. A spring 7 is provided inside the cover 6, with one end of the spring 7 abutting against the cover 6 and the other end of the spring 7 abutting against the elastic diaphragm 5. A pressure sensor 8 is fixedly connected to the inner end of the water outlet 1b, and the pressure sensor 8 can sense the pressure in the pressure chamber 1c.

[0023] The elastic diaphragm 5 is fixedly connected to the center of the force seat 9, and the outer side of the force seat 9 has a positioning protrusion 9a. The inner end face of the cover 6 is fixedly connected to the connecting post 6a. The two ends of the spring 7 are sleeved on the positioning protrusion 9a and the connecting post 6a, which has a good positioning effect on the spring 7 and avoids the spring 7 from shifting.

[0024] A metal heat sink 10 is fixedly connected to one side of the housing 1, and a sealing ring is provided between the metal heat sink 10 and the housing 1. This improves the heat dissipation effect, prevents water leakage, and extends the service life. A second metal heat sink 11 is provided on the outer side of the metal heat sink 10, and a boss 10a is provided on the outer side of the second metal heat sink 11. A heat dissipation hole 11a is provided in the middle of the second metal heat sink 11, and the heat dissipation hole 11a matches the boss 10a. The boss 10a passes through the heat dissipation hole 11a, so that the metal heat sink 10 and the second metal heat sink 11 are positioned. This has the advantages of simple structure, good positioning effect, and good heat dissipation effect.

[0025] On the other side of the housing 1, there is a control box 12, and the circuit board 4 is located inside the control box 12. The control box 12 has the advantages of good protection for the circuit board 4, reliable structure, and convenient assembly.

[0026] The check valve 2 is equipped with a guide post 13, one end of which is fixed to the check valve 2, and the other end of which is inserted into the inlet end 1a. This gives the check valve 2 a better guiding effect when it rises and falls, while also increasing the weight of the check valve 2 and improving the check valve effect.

[0027] During operation, circuit board 4 adjusts the output frequency of the controller in real time through logic operations based on the signals fed back from check valve 2 and pressure sensor 8, thereby adjusting the operating speed of the water pump motor to maintain the water pressure inside housing 1 at the same set value, thus achieving constant pressure water supply. When the user stops using water, check valve 2 returns to its original position, and its internal magnet 3 also returns to its original position. At the same time, circuit board 4 stops outputting based on the signal fed back from magnet 3, and the water pump stops working. When the faucet is opened, the pressure inside housing 1 decreases and drops to the set start-up pressure. Circuit board 4, based on the signal fed back from pressure sensor 8, causes the controller to resume output, and the water pump restarts. When there is a lack of water in housing 1, check valve 2 returns to its original position, and its internal magnet 3 also returns to its original position. At the same time, circuit board 4, based on the signals fed back from magnet 3 and pressure sensor 8, causes the controller to stop outputting, the water pump stops working, and the controller re-enters the water shortage protection state. When water flows through the water inlet end 1a and pushes open the check valve 2 to enter the cavity, when water flows into the shell 1, under the action of water pressure, the diaphragm deforms and squeezes the spring 7, and the push rod is displaced, so that a cavity with a buffering effect is formed in the head body, which can eliminate the water hammer effect and has the advantages of reliable and stable operation.

[0028] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.

[0029] Although this document frequently uses terms such as housing 1, inlet end 1a, outlet end 1b, pressure chamber 1c, buffer chamber 1d, check valve 2, magnet 3, circuit board 4, elastic diaphragm 5, cover 6, connecting post 6a, spring 7, pressure sensor 8, force seat 9, positioning protrusion 9a, metal heat sink 10, boss 10a, metal heat sink 11, heat dissipation hole 11a, control box 12, guide post 13, etc., the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
